Descripción
    FIELD OF THE INVENTION
  • [0001]
    The invention relates generally to devices or apparatus, which provide various methods and means to hang or store a cane or walking stick, when not in use for walking or support.
  • BACKGROUND OF THE INVENTION
  • [0002]
    Historically canes and walking sticks when not in use for walking or support are laid on floors, across chairs, benches and car seats, on tables, stood in corners, and leaned against a wall or a piece of furniture, and often times must be hand held when not in use for walking or support. Canes having a crook for a handgrip are sometimes hung on the backs of chairs and coat racks, but this method usually ends up with the cane on the floor or out of easy reach of the user.
  • [0003]
    Various tabletop cane holders are known and have been in use, however most such devices such as U.S. Pat. No. 4,895,330 by Richard F. Anstead, Jan. 23, 1990 refer only to a cane holder for attaching and detaching a cane from a table top or other generally planar surface. In examination of this patent it is apparent that the device is rather bulky, and may have sharp edges making it risky to carry always attached to a cane. This means that the cane holder must be carried separately to the point of use, or be installed and carried on a cane or installed on a tabletop or other planar surface to be available for use.
  • [0004]
    Another cane holder being marketed by several retail stores, namely The American Drug Supply Store, The Vermont Country Store, and CaneMart, which are on the Internet, is another source of prior art. The cane holder described is for canes up to ⅞ in. diameter, attaches to the cane by means of compressive spring tension, and then the cane holder is placed on the edge of a table, desk, or other generally planar surface, which allows the cane to balance from the edge of the aforementioned surfaces.
  • [0005]
    One may also use the cane holder under the table: placing the cane tip on the ground, then pushing the cane holder up the shaft of the cane, until it meets the bottom of the table, thereby creating tension between the floor and the table, which enables the cane to remain in an upright position under the table. The patent status or number for this “cane holder” has not been able to be determined at this time. These and other prior art on the subject matter are generally restricted to a single method or purpose of hanging a cane from: planar surfaces like a tabletop or countertop.
  • SUMMARY OF PRESENT INVENTION
  • [0006]
    The novelty of the present invention is that it provides a plurality of means and methods to perform the single purpose of hanging or storing a cane or walking stick, when its not in use for walking or support, from a plurality of objects and surfaces. The invention is comprised of five members: members one and two are removably attached to the cane or walking stick. Member three, the magnetic mount, is stored and carried on member two the moveable collar. Member four, the suction cup mount, is stored and carried on the vertical platform of member one a large inverted hook. Member five is a formed ferric metal plate that can be attached to vertical surfaces upon which member three, the magnetic mount, can be placed. This represents the most compact and readably accessible configuration of the present invention. The present invention provides two different methods and the means to hang or store a cane or walking stick from generally horizontal surfaces, rods, or rails such as: the back of a chair or wheelchair, a walker, clothes rod, coat rack, or handrail. This is accomplished by utilizing the inverted hooks of members one or two to engage and hang the cane or walking stick from the aforementioned objects. The invention also provides two different methods and the means to hang or store a cane or walking stick from a generally planar surface of varying thicknesses and textures such as: a conventional table, a wood grained or concrete picnic table, or a shelf or ledge. This is accomplished by utilizing the inverted hooks of members one or two of the invention to hang the cane or walking stick from the edge of said planar surface, or by using members one and two to capture said planar surface between members one and two. The present invention finally provides two methods and the means to hang or store a cane or walking stick from generally fixed vertical objects (ferric or non-ferric) such as: a wall, desk, stove, refrigerator, or motor vehicle. This is accomplished by means of utilizing the slotted portion of the inverted hook of member one to engage the head of a screw, nail, other suitably sized protrusions from said vertical objects, or the molded button portion of member three of the invention. Which is a removably attached magnetic member that can be placed on member five, a formed ferric metal plate, or independently of the ferric metal plate on any other ferric metal object.
