Abstract

Abstract There is provided by this invention an apparatus that can be placed on a flat surface and used conveniently for exercising the human foot under a variety of conditions. Beneath a support for the foot is positioned an element that affords pivotable relationship between the support and the flat surface, and fixed to the support there is at least one means for receiving an attachment for varying the conditions, such as the weight and the angle of use during the exercising. In other words, the attachments subject the foot during the exercising to such conditions as the amount of force or the amount of tilting that the foot must apply in order to activate the exercising device. The support for the foot can be in the form of a flat plate, generally made of wood or a plastic, underneath of which is positioned a rounded or ball-like member to allow for the said pivotable relationship at different positions. On the plate are receptacles, generally internally threaded which afford means for placing the said attachments, such as weights or levers, on the plate. The attachments may also be of such size and shape that effect tilting of the foot, and different attachments may be simultaneously attached to the apparatus.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 209 words
Adjustable apparatus for placement on a flat surface, such as a floor, to afford exercising of the human foot under a variety of conditions of weight and angles through the use of removable attachments to alter said weight or to change said angles, said apparatus comprising a support for said foot, said support being substantially larger than a human foot of average size and having securing means thereon for removably securing said attachments directly on the bottom, the top, and the side wall of said support, as desired, there being a plurality of differently-shaped foot inclining attachments and a plurality of differently configured supporting attachments, said attachments having means thereon for selective attachment to and removal from said support and for selective attachment to and removal from other attachments thereby affording a plurality of different configurations; at least one said supporting attachment being removably secured to said support beneath it thereby affording pivotable and rotational relationship, as desired, between said support and said surface; and said support securing means being a plurality of receptacles fixed to said support for securing one or more of said attachments to said apparatus, thereby allowing adjustments by combination of attachments to effect said alteration of weights and said changing of angles, as desired.
Claim 2
Dependent Claim 209 words
Adjustable apparatus for placement on a flat surface, such as a floor, to afford exercising of the human foot under a variety of conditions of weight and angles through the use of removable attachments to alter said weight or to change said angles, said apparatus comprising a support for said foot, said support being substantially larger than a human foot of average size and having securing means thereon for removably securing said attachments directly on the bottom, the top, and the side wall of said support, as desired, there being a plurality of differently-shaped foot inclining attachments and a plurality of differently configured supporting attachments, said attachments having means thereon for selective attachment to and removal from said support and for selective attachment to and removal from other attachments thereby affording a plurality of different configurations; at least one said supporting attachment being removably secured to said support beneath it thereby affording pivotable and rotational relationship, as desired, between said support and said surface; and said support securing means being a plurality of receptacles fixed to said support for securing one or more of said attachments to said apparatus, thereby allowing adjustments by combination of attachments to effect said alteration of weights and said changing of angles, as desired.
Claim 3
Dependent Claim 26 words
Apparatus in accordance with claim 1 in which said supporting attachment beneath said support is a rounded element affording a ball-like contact with said flat surface.
Claim 4
Dependent Claim 47 words
Apparatus in accordance with claim 1 in which said supporting attachment beneath said support has a height that places said support from about two inches to about twelve inches from said flat surface when said supporting attachment beneath said support is in contact with said flat surface.
Claim 5
Dependent Claim 14 words
Apparatus in accordance with claim 1 which includes an attachment that is a hook.
