482075000 | Elevated walking device (e.g., stilts, etc.) | 9 |
20090203504 | Extension system for mechanical stilts - An extension is provided for a standard mechanical stilt that is interfitted or telescoped between upper frame members and lower frame members of the standard mechanical stilt to thereby greatly increase the desired working length of the mechanical stilt. The extension consists of the same cross-sectional profiles as the standard stilt. The extension member may be interlocked with the standard stilt at any desired length. The extension frame has shock absorbing springs incorporated therein. | 08-13-2009 |
20090215590 | PORTABLE ATTACHMENT DEVICE AND METHOD FOR COMFORT AND SUPPORT - The present invention provides a system and a method for a portable attachment device. The portable attachment device includes a narrow attachment end, a wide wrap end, a fastening means on the narrow attachment end, a fastening means on the wide wrap end, and padding located within the wide wrap end. The portable attachment device is attachable to a first item by wrapping the narrow attachment end around a portion of the first item and attaching the narrow attachment end to a portion of the wide wrap end, securing the portable attachment device to the item. The first item is then attachable to a second item by wrapping the wide wrap end of the attachment device around the second item. In one embodiment the portable attachment device is used to secure the leg and calf of a wearer to a construction stilt, securely and comfortably holding the leg in place. | 08-27-2009 |
20100048361 | VERTICALLY ADJUSTABLE STILTS - A height adjustable stilt comprises a base and an extensible leg having a lower end secured to the base and an upper end. A foot support extends laterally from the extensible leg and is supported by the extensible leg. The foot support is height adjustable relative to the base as the extensible leg is extended or retracted. A height adjuster is configured to selectively extend the foot support relative to the base and configured to selectively fix the position of the foot support relative to the base. | 02-25-2010 |
20100093501 | Walking Stilts with Separate Heel and Toe Sections - A walking stilt includes a shoe platform and a floor platform connected by a support. The floor platform includes a heel section pivotally attached to the support and a separate and independently pivotable toe section pivotally attached to the support. The construction mimics an ankle joint and toe joints to provide a smooth rolling action while walking. | 04-15-2010 |
20110275490 | Stilt system - An industrial stilt generally includes a floor-engaging member having a heel portion and a toe portion, a load-bearing riser pivotally coupled with the heel portion of the floor-engaging member, a biasing assembly pivotally coupled with and between the toe portion of the floor-engaging member and the load-bearing riser, a foot-engaging member, a leg support assembly, and a leg cuff assembly. The biasing assembly assists in preventing excessive forward or backward leans and maintains the load-bearing riser and the user in a substantially vertical, upright position. The position of the leg cuff assembly on the user's leg and the user's elevation may be easily and safely adjusted using bracket and load-bearing riser adjustment and locking assemblies. Foot-engaging member is provided with multiple securing straps and ratchet buckle assemblies to permit secure and adjustable attachment of the stilt to the user's foot, and leg cuff assembly is provided with a strap, ratchet assembly, and cuff pad to enhance adjustment and user comfort. | 11-10-2011 |
20120004078 | STILTS WITH NON-CIRCULAR SUPPORT POLE AND METHOD OF IMPROVING SAFETY - Stilts for supporting a worker for doing elevated work, such as drywall installation, and methods of improving the safety of stilts, reducing the weight of stilts, and obtaining and providing stilts. Stilts each include a base member, a shoe plate, at least one (e.g., two) column(s), a leg-attachment mechanism, a support pole having a non-circular feature, and a guide that engages the non-circular feature to better resist twisting. In some embodiments, the non-circular feature is that the support pole has a non-circular cross section, such as an oval cross section. Inner and outer portions may telescopically engage to provide for height adjustment. | 01-05-2012 |
20160023050 | LIFT LID - A device for elevating height of a user comprising a pair of lids having a flat platform for receiving a footwear of the user, a pair of lifts attached to the pair of lids for elevating the pair of lids above a surface, an ankle strap attached to each of the pair of lids for securing ankle and heel of the footwear to the flat platform, the ankle strap having a y-shaped plastic structure, a first Velcro strip and a first adjustable strap, and a toe strap attached to each of the pair of lids for securing toe of the footwear to the flat platform, the toe strap having a pair of plastic strips, a second Velcro strip and a second adjustable strap. The pair of lifts may be replaced to adjust height of the device while allowing for mobility and continuity of task. | 01-28-2016 |
482076000 | Stilt having specific step | 2 |
20100062910 | Hand-Held Walking Stilts - A hand-held walking stilt comprising a base that contacts a walking surface, where the base has a foot stand to support a user's foot a set distance above the walking surface, where the foot stand defines an opening for a pole. The base also has at least one base flange extending into the opening. There is also a pole adapted to extend through the opening in the foot stand, and to extend above the base away from the walking surface, with the pole having at least one pole flange that interconnects with the base flange to hold the base and the pole together. | 03-11-2010 |
20110130251 | STILT DEVICES WITH COMMON LEG SUPPORT ASSEMBLIES - A stilt device having a front extendible strut and a cooperating rear extendible strut pivotally connected to a base member and a shoe plate, the front and rear extendible struts being disposed in a parallelogram relationship. The rear extendible strut has a rear member and a rear extendible member. A leg support pole is supported at one end by the rear extendible member and extends for its other end to be connected to a workman's leg to provide stability and to thereby enable the replacement of height determining extendible members, the distance from the shoe plate being a common vertical difference that is unchanged the extension of the extendible struts or by components thereof. For stilts of increased height the springs of the damping assemblies are selectively stiffened. | 06-02-2011 |
