BACKGROUND OF THE INVENTION
[0001]It is well recognized by those who are safety conscious that falls in the home, particularly in the bathroom, are a serious problem that impacts many households. Especially are the elderly and physically disadvantaged susceptible; although the physically normal and able-bodied are also vulnerable. The American Disability Act (ADA) mandates the installation and use of grab bars in facilities that serve the physically disadvantaged. However, grab bars are also readily available to the general public for installation in private residences as an assist and fall preventive measure when bathing or showering
[0002]As practical as it is to install fixed grab bars as a deterrent to falls in bathtubs and showers, testing by an independent agency has shown that their effectiveness can be greatly reduced if improperly connected to supporting walls. In a New York State laboratory test performed by the Eastern Paralyzed Veterans Association (EPVA) in April 2002, only two of five types of fixed-end connectors for grab bar installations were able to sustain the minimum loading required by state codes. Although portable grab bars are available, they are really assist bars only for they cannot meet the prescribed minimum safety loadings of state codes.
[0003]Regardless of the present method used to install fixed grab bars on existing walls having face tiles, holes for the fasteners must be drilled through the tiled surface. Special tools and skill are required to achieve a neat, successful installation. Having achieved such an installation, the homeowner will be committed to the location of the bar. To move or remove the grab bar in the future would require replacing or repairing and refurbishing the tiles in order that all signs of the original installation were removed
[0004]There are also circumstances that may require the use of a grab bar for a limited period of time. Such may be the case when an individual experiences an accident or undergoes surgery. During the recovery period, the person may require a means of support in the bathtub or shower. After full recovery has been achieved, the user may then choose to have the bar relocated or removed altogether. The process accompanying this decision can result in a noticeable expense for the limited time the fixed bar was in service.
SUMMARY OF THE INVENTION
[0005]The present invention overcomes these shortcomings and other limitations by providing assist means that do not require mechanical fasteners for installation in shower and tub/shower facilities. Therefore, the assist means are easily installed, removed or transferred from one location to another without involving mechanical fasteners in the process. The grip means part of the invention is a horizontal, rotatable grip bar extending from a first wall of a shower or tub/shower enclosure to a second wall that is opposite and generally parallel to the first wall. The grip bar parallels a third wall of the enclosure. Compressible means having significant gripping power attaches to each end of the horizontal bar and engages the first and second walls when the horizontal grip bar is rotated about its longitudinal axis. This causes the compressible means to experience a compressive axial force substantially clamping the bar between the walls engaging the compressible means. Suction means such as suction cups or vacuum cups attached to brackets encircling the grip bar are mounted perpendicular to the bar and the parallel wall. The suction cups develop tensile forces that secure the grip bar to the wall, thereby providing lateral stability to the bar when the user showers in either a shower enclosure or in a tub/shower facility.
[0006]Where the user has tub/shower accommodations but predominately bathes, the present invention includes vertical supports attached to the horizontal grip bar. The vertical supports strengthen the grip bar permitting the user to pull up from a sitting to a standing position using a lift bar attached to the grip bar and a vertical support. The vertical supports also transform the grip bar into a means capable of withstanding the safety loading prescribed by state codes for ADA compliance. Further, to aid in entering and exiting a bathtub, an entry bar attaches to the horizontal grip bar spanning across the tub and descending vertically to engage the opposite rim of the bathtub by means of a bracket.
[0007]For the user having a free-standing bathtub in an area without adjacent walls; the vertical supports extend from the rim of the bathtub to the ceiling terminating with compressible means. The horizontal grip bar connects to the vertical supports. The user also has the entry bar and the lift bar available as previously described. Thus the present invention provides users of shower and bath facilities secure means of support and assistance on entering and exiting each facility.
[0008]One of the principal objectives of the present invention is to provide assist means that can be easily assembled, installed, and removed without the use of mechanical fasteners.
[0009]Another objective is to provide user lift and support means in a tub/shower facility that meets the load requirements of state codes without the use of mechanical fasteners for attachment to supporting walls.
[0010]Another objective is to provide assist means that can be easily adjusted vertically within the enclosure.
[0011]Another objective is to provide grip means with calibrated means making the installation of the grip means independent of the varying strength of the installers.
[0012]Another objective is to provide assist means that maintain a stable support system under all required conditions.
[0013]These and other objects and advantages of the invention will become apparent after considering the following detailed specification and accompanying drawings which cover a preferred embodiment wherein:

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0027]Referring to the views specifically, FIG. 1 shows grip means 50 constructed according to the present invention for installation in a shower enclosure and tub/shower enclosure having walls defined by numbers 19, 36, and 37 and ceiling 34 of FIG. 2. Included also in FIG. 2 is bathtub 35, with shower head 38, faucet 39, and spout 40. The grip means comprises grip bar 20 rotatively connecting to compressible means 21 shown in FIG. 2 and, more distinctly, in FIGS. 4 and 5. As shown in FIG. 4, grip bar 20 seats insert 21B; said insert having internal threads 21C to engage external threads of stud 21A; said stud being fixedly embedded in compressible means 21. Said compressible means comprises suction cups, disks, covered with or constructed of compressible material, or like means; each capable of expelling air trapped between face of said compressible means and a parallel surface and forcefully gripping said surface under the influence of an externally applied compressive force. FIGS. 1, 2 and 5 show the opposite end of grip bar 20 engaging compressible means 21 through a smooth hole 21F of insert 21E and smooth stud 21G; said inserts 21B and 21E being fixedly attached to the interior of grip bar 20 by welds or other means compatible with the material used.
[0028]In FIG. 1, intermediate between compressible means 21 on grip bar 20, and in FIG. 10; tensile brackets 22D encircle said grip bar and connect tensile means 22 to grip bar 20 by means of internal threads 22B located in said bracket means and threaded stud 22A fixedly embedded in tensile means 22. In FIG.19 tensile means 22 comprise suction means such as suction cups, vacuum cups, or like means capable of expelling air trapped between face of said tensile means and wall surface 19 and forcefully gripping wall surface 19 when said cups are pressed forcibly against said wall.
[0029]In the process of installing grip means 50 of FIG. 1, tensile means 22 of FIG. 10 are positioned and forced to engage said wall surface 19 thereby developing the tensile capacity of said suction cups. Said tensile means are movable along grip bar 20 by means of tensile brackets 22D; said brackets being secured to grip bar 20 by means of fasteners 22E after desired placement.
[0030]Following installation of tensile means 22; grip bar 20 is rotated about its longitudinal axis such that threads 21C of insert 21B in FIG. 4 securely engage said threads of stud 21A; whereas in FIG. 5, hole 21F permits insert 21E to simultaneously rotate freely on stud 21G. The rotational energy applied to grip bar 20 is converted to an axial compressive force by the threaded means of stud 21A and insert 21B; said force traversing the longitudinal axis of grip means 50. Count-indicator 26 in FIGS. 1, 2, 3 and 6, in combination with threaded stud 21A and threaded hole 21C in FIG. 4, cooperate as a mechanism assisting in numbering the revolutions of grip bar 20. The number of revolutions of said bar determines the magnitude of the axial compressive force said bar applies to compressible means 21. The value of said force is essential to forming a rigid and safe support system between said walls 36 and 37 in FIG. 2 and grip bar 20. An established relationship between the number of revolutions of grip bar 20 and the axial force applied to walls 36 and 37 in 50 in FIG. 1 relieves the installer of the responsibility of determining the number of revolutions that will consistently provide a strong and safe installation. Covering means 21D and 22C in FIGS. 4 and 10, each having sealing means 33, are placed over aforesaid compressive and tensile means completing the installation. Said covering means consists of an escutcheon having sealing means in the form of a rubber ring or similar material encircling the periphery of said escutcheon.
[0031]FIG. 2 shows the components of grip means 50 incorporated into assist means 55. Assist means 55 comprises a portion of the invention providing the means whereby a bather sitting in a tub can lift up to a standing position and exit the tub safely using means to be described. Comprising assist means 55 are said grip means 50, lift means having lift bar 32, entry means with entry bar 31, and vertical support means 27, connected through fittings, and engaging tub 35 as shown and hereafter defined.
[0032]Vertical tube 27 connects to grip bar 20 through eye fitting 23 and engages bathtub 35 through retaining means; said retaining means comprising tensile means 28 and retaining cover 29. The upper extremity of vertical tube 27 extends into a vertical section of eye fitting 23; said fitting also having an upper segment encircling the circumference and retaining grip bar 20 as shown in FIG. 7. Tensile means 28, shown generally in FIG. 2 and in greater detail in FIG. 9, being located at the lower extremity of said vertical tube 27 functions similarly to tensile means 22 in FIG. 10 to engage tub 35. Referring to FIG. 9, tensile means 28 of said retaining means engages retaining cover 29 through the external threads of stud 28A mating with internal threads of hole 29A. Tensile means 28 and retaining cover 29 of said retaining means provide vertical and lateral stability to vertical support 27 atop bathtub 35.
[0033]Lift means shown in FIG. 2 comprises lift bar 32 and tee fittings 25; said fittings connect said lift bar to horizontal grip bar 20 and vertical support means 27. As shown in FIG. 8, tee fitting 25 secures buttons 25A, locking lift bar 32 to grip bar 20. The operation of spring 25C in combination with push buttons 25A and retainers 25B releases said lift bar. When buttons 25A are pushed into the cavity of lift bar 32, said lift bar becomes separated from tee fitting 25 and removable from assist means 55. Aforesaid components, buttons 25A, retainers 25B, and spring 25C of FIG. 8 define the release means providing coupling and decoupling means for the preferred embodiment.
[0034]For a user needing assistance entering and exiting bathtub 35; entry means shown in FIGS. 2, 3 and 11, including entry bar 31, tee fitting 25, tensile means 28, and rim bracket 30, comprise a segment of the present invention for that purpose. FIG. 11 shows the horizontal section of entry bar 31 engaging tee fitting 25 and being secured by buttons 25A of release means shown in FIG. 8 and described previously. As shown in FIG. 12 the lower extremity of said bar 31 enters into and bears on rim bracket 30 and tensile means 28; said rim bracket in FIG. 11 grasps the rim of bathtub 35 to provide stability in concert with tensile means 28; said tensile means engaging the rim of tub 35 in the manner of a suction cup thereby providing vertical and longitudinal stability to entry bar 31. Rim bracket 30 connects with tensile means 28 through threaded stud 28A embedded in tensile means 28; external threads of said stud mating with internal threads of hole 30A of rim bracket 30 in FIG. 12. Rim bracket 30 and tensile means 28, in combination, designated as holding means.
[0035]Assist means 60 in FIG. 3 is constructed according to the present invention and configured for vertical support 43 to engage ceiling 34 and bathtub 35. Said bathtub, being free-standing, does not permit grip bar 20 to engage walls as in FIG. 2. Assist means 60 comprises vertical supports 43, having compressible means 21, as in FIGS. 3 and 4, attaching to upper extremity of said members 43 and engaging ceiling 34. FIG. 12 shows the lower extremity of vertical support 43 residing in and bearing on rim bracket 30 and tensile means 28. Said rim bracket engages the rim of bathtub 35, as shown in FIG. 3, to provide lateral stability in conjunction with tensile means 28; said tensile means providing vertical and longitudinal stability to vertical support 43, in particular, and to assist means 60, in general. FIG. 12 shows the relationship between rim bracket 30 and tensile means 28. Said rim bracket connects with tensile means 28 through external threads of stud 28A embedded in said tensile means and engages internal threads of hole 30A of rim bracket 30 as heretofore described.
[0036]FIG. 13 shows the connectivity between grip bar 20 and vertical support 43, by means of tee fitting 25. Said vertical support passes continuously through the vertically open segment of tee fitting 25 while said grip bar terminates in the open horizontal segment of said fitting means. Tee fitting 25 permits decoupling of grip bar 20 and support means 43 through pin assembly components 25A through 25C in FIG. 8, as heretofore described. Grip bar 20, shown in FIGS. 1, 2, and 3 comprises a tubular section formed from metallic or plastic material having structural rigidity and strength.
[0037]During the installation process vertical support 43, having compressive means 21 attaching to its upper extremity, is rotated about its vertical axis such that internal threads 21C of insert 21B, shown in FIG. 4, rotatively engage external threads of stud 21A; whereas FIG. 12 shows the lower extremity of said vertical support simultaneously rotating freely inside the smooth vertical component of rim bracket 30. Count-indicator 26 in FIGS. 1, 2, 3, and 6, threaded stud 21A, and threaded hole 21C in FIG. 4, cooperate to assist in tracking the number of revolutions of vertical support 43. Controlling the number of revolutions assures the proper axial compressive force in vertical support 43. The relationship between the number of revolutions of said vertical support 43 and the axial force developed between tensile means 28 and compressive means 21 relieves the installer from the sole responsibility of determining what is a strong and safe installation. Covering means 21D in FIG. 4 and FIG. 5, having sealing means 33, is placed over compressive means 21 when the installation of assist means 60 is complete.

Description:
BACKGROUND OF THE INVENTION
[0001]It is well recognized by those who are safety conscious that falls in the home, particularly in the bathroom, are a serious problem that impacts many households. Especially are the elderly and physically disadvantaged susceptible; although the physically normal and able-bodied are also vulnerable. The American Disability Act (ADA) mandates the installation and use of grab bars in facilities that serve the physically disadvantaged. However, grab bars are also readily available to the general public for installation in private residences as an assist and fall preventive measure when bathing or showering
[0002]As practical as it is to install fixed grab bars as a deterrent to falls in bathtubs and showers, testing by an independent agency has shown that their effectiveness can be greatly reduced if improperly connected to supporting walls. In a New York State laboratory test performed by the Eastern Paralyzed Veterans Association (EPVA) in April 2002, only two of five types of fixed-end connectors for grab bar installations were able to sustain the minimum loading required by state codes. Although portable grab bars are available, they are really assist bars only for they cannot meet the prescribed minimum safety loadings of state codes.
[0003]Regardless of the present method used to install fixed grab bars on existing walls having face tiles, holes for the fasteners must be drilled through the tiled surface. Special tools and skill are required to achieve a neat, successful installation. Having achieved such an installation, the homeowner will be committed to the location of the bar. To move or remove the grab bar in the future would require replacing or repairing and refurbishing the tiles in order that all signs of the original installation were removed
[0004]There are also circumstances that may require the use of a grab bar for a limited period of time. Such may be the case when an individual experiences an accident or undergoes surgery. During the recovery period, the person may require a means of support in the bathtub or shower. After full recovery has been achieved, the user may then choose to have the bar relocated or removed altogether. The process accompanying this decision can result in a noticeable expense for the limited time the fixed bar was in service.
SUMMARY OF THE INVENTION
[0005]The present invention overcomes these shortcomings and other limitations by providing assist means that do not require mechanical fasteners for installation in shower and tub/shower facilities. Therefore, the assist means are easily installed, removed or transferred from one location to another without involving mechanical fasteners in the process. The grip means part of the invention is a horizontal, rotatable grip bar extending from a first wall of a shower or tub/shower enclosure to a second wall that is opposite and generally parallel to the first wall. The grip bar parallels a third wall of the enclosure. Compressible means having significant gripping power attaches to each end of the horizontal bar and engages the first and second walls when the horizontal grip bar is rotated about its longitudinal axis. This causes the compressible means to experience a compressive axial force substantially clamping the bar between the walls engaging the compressible means. Suction means such as suction cups or vacuum cups attached to brackets encircling the grip bar are mounted perpendicular to the bar and the parallel wall. The suction cups develop tensile forces that secure the grip bar to the wall, thereby providing lateral stability to the bar when the user showers in either a shower enclosure or in a tub/shower facility.
[0006]Where the user has tub/shower accommodations but predominately bathes, the present invention includes vertical supports attached to the horizontal grip bar. The vertical supports strengthen the grip bar permitting the user to pull up from a sitting to a standing position using a lift bar attached to the grip bar and a vertical support. The vertical supports also transform the grip bar into a means capable of withstanding the safety loading prescribed by state codes for ADA compliance. Further, to aid in entering and exiting a bathtub, an entry bar attaches to the horizontal grip bar spanning across the tub and descending vertically to engage the opposite rim of the bathtub by means of a bracket.
[0007]For the user having a free-standing bathtub in an area without adjacent walls; the vertical supports extend from the rim of the bathtub to the ceiling terminating with compressible means. The horizontal grip bar connects to the vertical supports. The user also has the entry bar and the lift bar available as previously described. Thus the present invention provides users of shower and bath facilities secure means of support and assistance on entering and exiting each facility.
[0008]One of the principal objectives of the present invention is to provide assist means that can be easily assembled, installed, and removed without the use of mechanical fasteners.
[0009]Another objective is to provide user lift and support means in a tub/shower facility that meets the load requirements of state codes without the use of mechanical fasteners for attachment to supporting walls.
[0010]Another objective is to provide assist means that can be easily adjusted vertically within the enclosure.
[0011]Another objective is to provide grip means with calibrated means making the installation of the grip means independent of the varying strength of the installers.
[0012]Another objective is to provide assist means that maintain a stable support system under all required conditions.
[0013]These and other objects and advantages of the invention will become apparent after considering the following detailed specification and accompanying drawings which cover a preferred embodiment wherein:

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0027]Referring to the views specifically, FIG. 1 shows grip means 50 constructed according to the present invention for installation in a shower enclosure and tub/shower enclosure having walls defined by numbers 19, 36, and 37 and ceiling 34 of FIG. 2. Included also in FIG. 2 is bathtub 35, with shower head 38, faucet 39, and spout 40. The grip means comprises grip bar 20 rotatively connecting to compressible means 21 shown in FIG. 2 and, more distinctly, in FIGS. 4 and 5. As shown in FIG. 4, grip bar 20 seats insert 21B; said insert having internal threads 21C to engage external threads of stud 21A; said stud being fixedly embedded in compressible means 21. Said compressible means comprises suction cups, disks, covered with or constructed of compressible material, or like means; each capable of expelling air trapped between face of said compressible means and a parallel surface and forcefully gripping said surface under the influence of an externally applied compressive force. FIGS. 1, 2 and 5 show the opposite end of grip bar 20 engaging compressible means 21 through a smooth hole 21F of insert 21E and smooth stud 21G; said inserts 21B and 21E being fixedly attached to the interior of grip bar 20 by welds or other means compatible with the material used.
[0028]In FIG. 1, intermediate between compressible means 21 on grip bar 20, and in FIG. 10; tensile brackets 22D encircle said grip bar and connect tensile means 22 to grip bar 20 by means of internal threads 22B located in said bracket means and threaded stud 22A fixedly embedded in tensile means 22. In FIG.19 tensile means 22 comprise suction means such as suction cups, vacuum cups, or like means capable of expelling air trapped between face of said tensile means and wall surface 19 and forcefully gripping wall surface 19 when said cups are pressed forcibly against said wall.
[0029]In the process of installing grip means 50 of FIG. 1, tensile means 22 of FIG. 10 are positioned and forced to engage said wall surface 19 thereby developing the tensile capacity of said suction cups. Said tensile means are movable along grip bar 20 by means of tensile brackets 22D; said brackets being secured to grip bar 20 by means of fasteners 22E after desired placement.
[0030]Following installation of tensile means 22; grip bar 20 is rotated about its longitudinal axis such that threads 21C of insert 21B in FIG. 4 securely engage said threads of stud 21A; whereas in FIG. 5, hole 21F permits insert 21E to simultaneously rotate freely on stud 21G. The rotational energy applied to grip bar 20 is converted to an axial compressive force by the threaded means of stud 21A and insert 21B; said force traversing the longitudinal axis of grip means 50. Count-indicator 26 in FIGS. 1, 2, 3 and 6, in combination with threaded stud 21A and threaded hole 21C in FIG. 4, cooperate as a mechanism assisting in numbering the revolutions of grip bar 20. The number of revolutions of said bar determines the magnitude of the axial compressive force said bar applies to compressible means 21. The value of said force is essential to forming a rigid and safe support system between said walls 36 and 37 in FIG. 2 and grip bar 20. An established relationship between the number of revolutions of grip bar 20 and the axial force applied to walls 36 and 37 in 50 in FIG. 1 relieves the installer of the responsibility of determining the number of revolutions that will consistently provide a strong and safe installation. Covering means 21D and 22C in FIGS. 4 and 10, each having sealing means 33, are placed over aforesaid compressive and tensile means completing the installation. Said covering means consists of an escutcheon having sealing means in the form of a rubber ring or similar material encircling the periphery of said escutcheon.
[0031]FIG. 2 shows the components of grip means 50 incorporated into assist means 55. Assist means 55 comprises a portion of the invention providing the means whereby a bather sitting in a tub can lift up to a standing position and exit the tub safely using means to be described. Comprising assist means 55 are said grip means 50, lift means having lift bar 32, entry means with entry bar 31, and vertical support means 27, connected through fittings, and engaging tub 35 as shown and hereafter defined.
[0032]Vertical tube 27 connects to grip bar 20 through eye fitting 23 and engages bathtub 35 through retaining means; said retaining means comprising tensile means 28 and retaining cover 29. The upper extremity of vertical tube 27 extends into a vertical section of eye fitting 23; said fitting also having an upper segment encircling the circumference and retaining grip bar 20 as shown in FIG. 7. Tensile means 28, shown generally in FIG. 2 and in greater detail in FIG. 9, being located at the lower extremity of said vertical tube 27 functions similarly to tensile means 22 in FIG. 10 to engage tub 35. Referring to FIG. 9, tensile means 28 of said retaining means engages retaining cover 29 through the external threads of stud 28A mating with internal threads of hole 29A. Tensile means 28 and retaining cover 29 of said retaining means provide vertical and lateral stability to vertical support 27 atop bathtub 35.
[0033]Lift means shown in FIG. 2 comprises lift bar 32 and tee fittings 25; said fittings connect said lift bar to horizontal grip bar 20 and vertical support means 27. As shown in FIG. 8, tee fitting 25 secures buttons 25A, locking lift bar 32 to grip bar 20. The operation of spring 25C in combination with push buttons 25A and retainers 25B releases said lift bar. When buttons 25A are pushed into the cavity of lift bar 32, said lift bar becomes separated from tee fitting 25 and removable from assist means 55. Aforesaid components, buttons 25A, retainers 25B, and spring 25C of FIG. 8 define the release means providing coupling and decoupling means for the preferred embodiment.
[0034]For a user needing assistance entering and exiting bathtub 35; entry means shown in FIGS. 2, 3 and 11, including entry bar 31, tee fitting 25, tensile means 28, and rim bracket 30, comprise a segment of the present invention for that purpose. FIG. 11 shows the horizontal section of entry bar 31 engaging tee fitting 25 and being secured by buttons 25A of release means shown in FIG. 8 and described previously. As shown in FIG. 12 the lower extremity of said bar 31 enters into and bears on rim bracket 30 and tensile means 28; said rim bracket in FIG. 11 grasps the rim of bathtub 35 to provide stability in concert with tensile means 28; said tensile means engaging the rim of tub 35 in the manner of a suction cup thereby providing vertical and longitudinal stability to entry bar 31. Rim bracket 30 connects with tensile means 28 through threaded stud 28A embedded in tensile means 28; external threads of said stud mating with internal threads of hole 30A of rim bracket 30 in FIG. 12. Rim bracket 30 and tensile means 28, in combination, designated as holding means.
[0035]Assist means 60 in FIG. 3 is constructed according to the present invention and configured for vertical support 43 to engage ceiling 34 and bathtub 35. Said bathtub, being free-standing, does not permit grip bar 20 to engage walls as in FIG. 2. Assist means 60 comprises vertical supports 43, having compressible means 21, as in FIGS. 3 and 4, attaching to upper extremity of said members 43 and engaging ceiling 34. FIG. 12 shows the lower extremity of vertical support 43 residing in and bearing on rim bracket 30 and tensile means 28. Said rim bracket engages the rim of bathtub 35, as shown in FIG. 3, to provide lateral stability in conjunction with tensile means 28; said tensile means providing vertical and longitudinal stability to vertical support 43, in particular, and to assist means 60, in general. FIG. 12 shows the relationship between rim bracket 30 and tensile means 28. Said rim bracket connects with tensile means 28 through external threads of stud 28A embedded in said tensile means and engages internal threads of hole 30A of rim bracket 30 as heretofore described.
[0036]FIG. 13 shows the connectivity between grip bar 20 and vertical support 43, by means of tee fitting 25. Said vertical support passes continuously through the vertically open segment of tee fitting 25 while said grip bar terminates in the open horizontal segment of said fitting means. Tee fitting 25 permits decoupling of grip bar 20 and support means 43 through pin assembly components 25A through 25C in FIG. 8, as heretofore described. Grip bar 20, shown in FIGS. 1, 2, and 3 comprises a tubular section formed from metallic or plastic material having structural rigidity and strength.
[0037]During the installation process vertical support 43, having compressive means 21 attaching to its upper extremity, is rotated about its vertical axis such that internal threads 21C of insert 21B, shown in FIG. 4, rotatively engage external threads of stud 21A; whereas FIG. 12 shows the lower extremity of said vertical support simultaneously rotating freely inside the smooth vertical component of rim bracket 30. Count-indicator 26 in FIGS. 1, 2, 3, and 6, threaded stud 21A, and threaded hole 21C in FIG. 4, cooperate to assist in tracking the number of revolutions of vertical support 43. Controlling the number of revolutions assures the proper axial compressive force in vertical support 43. The relationship between the number of revolutions of said vertical support 43 and the axial force developed between tensile means 28 and compressive means 21 relieves the installer from the sole responsibility of determining what is a strong and safe installation. Covering means 21D in FIG. 4 and FIG. 5, having sealing means 33, is placed over compressive means 21 when the installation of assist means 60 is complete. Said sealing means 33, being of flexible composition, seals off the contact surface inside of cover 21D from moisture.
[0038]Entry means having bar 31, and lift means having bar 32, in assist means 60 are identical in construction and performance to said entry means and said lift means heretofore described in assist means 55.
