DETAILED DESCRIPTION

[0022] It is very difficult to perform a proper sit-up without having one's feet held in place. Physical fitness tests, especially in the military and at police academies, for example, require that one's feet be held in place during sit-ups. This requires the individuals to team up with partners, thus losing efficiency. In preparation for such tests and for one's own fitness goals, it is desirable to practice sit-ups in preparation for such a test while having one's feet held in place. Often, another person is not available to hold one's feet in place in the practice setting. Placing feet under heavy furniture is awkward; the furniture may move or feet could slide out from under the furniture. It is desirable to have a device that would allow a person to perform the required sit-ups alone or without the need for switching between foot holder and sit-up performer, thus saving time and guaranteeing a firm grip on the performer's feet.

[0023] The device of the present disclosure provides a solution to the problem of holding one's feet in place during sit-ups. The device holds a user's feet in place in two ways. First, the user's heels abut a heel block to keep the feet from sliding back toward one's body. Next, a strap runs from an outside of one foot, over the top of both feet adjacent to the ankles, and to the outside of the second foot, holding the feet together and down on the device. The strap prevents the feet from moving forward away from the body and from moving upwards away from the surface.

[0024] Refer to FIGS. 1 and 2 where two preferred embodiments of the present disclosure are illustrated. In FIG. 1, the device 10 has a length such that an average sized person's shoulder blades will touch the surface of the device when the person is lying prone on the device so that it can be used for official testing. Preferably, the device will have a length of at least four feet in order to achieve this objective. However, in certain situations and for practicing purposes, the device could be shorter so that only a person's feet and buttocks fit on the board. This option 11 is shown in FIG. 2.

[0025] The sit-up device is preferably made of a lightweight yet strong composite plastic material with an optional metal core for rigidity. The heel block 12 is preferably molded as part of the backboard 10 or 11. The heel block should have a length of about 8 to 10 inches, a width of about 1/4 inch if made from a strong metal to 2 inches if made of a composite or hollow molded material or wood, and a height of 1.5 to 2.5 inches. Attached to the backboard 10 or 11 is a strap 14. Preferably, the strap 14 is treaded down through a first slot 13, underneath the backboard, and up through a second slot 13. FIG. 1 shows the strap 14 in a closed position. FIG. 2 shows the strap an open position. The foot strap 14 must be strong and secure so as to avoid opening during the sit-up repetitions, yet easy enough to get in and out of quickly. Preferably, a cam buckle, such as used for a seatbelt, and a lap belt type strap will be used. It must be easy to strap and unstrap, yet very secure and adjustable for different sized footwear. For example, FIG. 1 shows an automobile-type buckle 15N/15B. FIG. 2 shows an airline-type cam buckle 17A/17B. Any other suitable strap and closure mechanism may be employed.

[0026] A thin, durable, cleanable, flat pad 16 is attached on the entire top side of the backboard 10 or 11 to cushion the lower back and buttocks, or just the buttocks, respectively, during the movement. The pad 16 is equivalent to a gym mat or yoga mat in that it does not enhance or hamper a traditional physical agility test sit-up. Preferably the pad 16 is permanently attached to the top surface of the backboard 10 or 11 with adhesives so that it cannot accidentally come loose during use. A hook and loop attachment option may be viable so that the pad can be replaced if the pad wears out or to offer thicker pad options for certain users' comfort.

[0027] The bottom surface of the backboard 18, shown in FIGS. 5A and 5B, is fitted with a non-slip rubber material 20 so that the unit will not slide on a slick floor as in a gymnasium during the sit-ups. The rubber material may be placed in strips 20 as shown in FIG. 5A, or in other orientations including coverage of the entire bottom surface, as shown in FIG. 5B, if desired.

[0028] The sit-up board of the present disclosure can be stored easily for use in many settings. Police academies, schools, fitness centers, and homeowners would be interested in using this device. It can be slid under a bed, in a closet, behind a couch, etc., in home use when being stored as it will be relatively flat and lightweight. In a school or academy type setting, a specially designed wheeled rack can be used so the units can be stacked together upright or flat and rolled into a storage area.

[0029] FIGS. 3 and 4 illustrate a preferred use of the device of the present disclosure. FIG. 3 illustrates the longer backboard 10 where the user's shoulder blades are supported by the backboard. Strap 14 is shown buckled and tightened over and around the user's feet. The user's heels are abutted to the heel block 12. In FIG. 4, a shorter backboard 11 is provided. Only the user's feet and buttocks are accommodated by the backboard 11. It will be understood that the figures are not drawn to scale.

[0030] FIGS. 6A-6C illustrate a third preferred embodiment of the present disclosure. In a practice setting, it may be desirable to allow a user to achieve a slight incline or decline position. This would be achieved by integrating a short fold down leg system on the top end and bottom end of the backboard. FIG. 6C illustrates the underside 18 of the backboard 10. Legs 32 are shown in a folded position at a top end of the backboard and legs 36 are shown in a folded position at a bottom end of the backboard. Legs 32 and 36 clip into recesses 34 and 38, respectively, in the bottom surface 18 of the backboard.

[0031] As shown in FIG. 6A, for an inclined position, the legs 32 at the top end of the backboard 10 are unfolded and locked into place using bar 40, for example. Preferably, the legs have a height H of between about 8 and 14 inches. FIG. 6B shows bottom legs 36 locked in the unfolded position to form a decline. For stability, the legs should be as wide as the board or close to it. Rubber grips 42 on the bottom of the legs will prevent them from sliding on the smooth surface of a floor. The legs could have several height settings using sets of holes 44 with a locking pin that goes through the holes.

[0032] In a fourth preferred embodiment of the present disclosure, shown in FIGS. 7A and 7B, a fold up model backboard is shown. The backboard has two sections 100A and 100B. As illustrated in FIG. 7A, hinge 102 allows 100B to fold underneath 100A. The backboard can be used in this position, similarly to the short backboard 11 that accommodates the user's feet and buttocks only. If a longer backboard is desired to support the user's shoulder blades, as in backboard 10, as illustrated in FIG. 7B, the underneath section 100B is unfolded and locked into the open position adjacent to section 100A. Comfort pad section 16A abuts section 16B. For example, a thin metal flat bar could be slid into slots on each side of the hinged area, thus not allowing it to fold or unfold until the bar is removed. This backboard option 100A/100B allows for either a short or a long backboard and may be more easily stored in the folded position.

[0033] A handle 104 could be incorporated somewhere on the end for short term transportation. Possibly straps could be fitted onto the backboard so that the user could wear it like a backpack for efficient prolonged transportation.

[0034] The sit-up board of the present disclosure is lightweight, compact, and easy to use to hold a person's feet firmly in place while practicing sit-ups or while taking an official sit-up fitness test.

[0035] Although the preferred embodiment of the present disclosure has been illustrated, and that form has been described in detail, it will be readily understood by those skilled in the art that various modifications may be made therein without departing from the spirit of the disclosure or from the scope of the appended claims.
