摘要 | An apparatus for supporting a user comprising a platform extending between first and second edges each having two corners, a frame having four substantially parallel uprights located proximate to each of the first and second edges of the platform, each of said uprights slidably locating said platform proximate to a corner of said platform and an elastic support member extending between each of the first and second edges of the platform and the frame so as suspend the platform from the frame. The platform is biased from a first position located proximate to a ground surface to a second position vertically spaced above the first position by the elastic support members, wherein said first and second positions are substantially parallel to each other. | ||||||

说明书全文 | 1. Field of Invention The present invention relates to support devices in general and in particular to a method and apparatus for supporting and assisting a user to get into and out of a kneeling position. 2. Description of Related Art Kneeling is a position which is frequently difficult or uncomfortable for many people. Many people have difficulty with the act of getting into and staying in a kneeling position. In particular, many people find remaining in a kneeling position to be hard on the outer surface of their knees. This is particularly the case where the person is kneeling on rough or hard surfaces. A further difficulty many people experience is the act of lowering themselves into a kneeling position from a standing position. It will also be appreciated that the movement of returning to standing from a kneeling position is likewise similarly difficult for such people. Such movements may be difficult for people either due to reduced muscular strength or due to injury or weakness within their knees themselves. For other people, the movement into and out of a kneeling position places a painful level of strain on their back. Previous attempts have been made to provide knee supports for a user so as to reduce the difficulty required to get into and out of as well as remain in a kneeling position. Some attempts have been made to provide a padded surface on which the user may kneel. Such devices have located such surface at a fixed position which does not however aided the user in getting into and out of the kneeling position. Examples of such devices may be found in U.S. Pat. No. 4,763,756 issued Aug. 16, 1988 to Horan. According to a first embodiment of the present invention there is disclosed an apparatus for supporting a user comprising a platform extending between first and second edges each having two corners, a frame having four substantially parallel uprights located proximate to each of the first and second edges of the platform, each of said uprights slidably locating said platform proximate to a corner of said platform and an elastic support member extending between each of the first and second edges of the platform and the frame so as suspend the platform from the frame. The platform is biased from a first position located proximate to a ground surface to a second position vertically spaced above the first position by the elastic support members, wherein said first and second positions are substantially parallel to each other. The platform may be substantially rectangular. The platform may have two corners defining each of the first and second edges. The platform may include padded sections. The elastic support members may extend between the two corners defining the first and second edges over the frame. The elastic support members may provide an upward biasing force to the platform of between 10 and 200 pounds force. The frame may comprise a pair of spaced apart inverted loops with the platform therebetween. The corners of the platform may be slidably supported by the frame. The elastic support members are contained within hollow sections of the frame. Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures. In drawings which illustrate embodiments of the invention wherein similar characters of reference denote corresponding parts in each view, Referring to The platform 12 extends between first and second side edges, 16 and 18, respectively and front and rear edges 20 and 22, respectively. The platform 12 may optionally include padded portions 24 on the top surface 14 thereof sized and positioned to receive the knees of a user thereon which may comprise a portion or the entire top surface of the platform. The platform 12 may be substantially rectangular as illustrated or any other suitable outline, such as, by way of non-limiting example, square, oval, circular, octagonal, hexagonal or irregular. The platform may be formed of any suitable material, such as, by way of non-limiting example wood, metal, plastic or composite materials and may have a thickness sufficient to support the weight of the user thereon. The platform 12 will further have a size selected to be able to receive a user thereon while permitting such a user to grasp the top portions of the frame for support. In practice, it has been found that a width of between 6 and 12 inches (152 and 305 mm) and a length of between 18 and 30 inches (457 and 762 mm) has been useful although it will be appreciated that other dimensions for the platform may be useful as well. The platform 12 may be angularly oriented, by an angle, generally indicated at 25 such that the front edge 20 is higher than the rear edge 22. The angle 25 assists in providing a more comfortable position for the user and may be selected to be any angle between 0 and 30 degrees. The frame 30 comprises a pair of parallel space spaced apart inverted u-shaped members 32 each comprising front and rear uprights, 34 and 36, respectively with a top connecting portion 38 between the top ends thereof. As illustrated in Each slot 42 includes a support sleeve 50 associated therewith for supporting a corner of the platform 12. With reference to With reference to In operation, a user approaches the apparatus from the rear and places their knees 6 upon the pads 24. The user then permits their weight to press the platform downward to the position illustrated in With reference to With reference to While specific embodiments of the invention have been described and illustrated, such embodiments should be considered illustrative of the invention only and not as limiting the invention as construed in accordance with the accompanying claims. |
