Abstract
Abstract Calf-exercising apparatus including a unit for each leg, with each unit including a foot-engaging platform for supporting the weight of the user. The elevational and lateral angles of each platform are independently adjustable, so that the attitude of each platform can be varied and controlled, and thereby provide a wide range of settings whereby the user can selectively choose the degree of difficulty and amount of stress that is required to perform the exercises. The foot-engaging platforms are provided on separate units that are pivotally connected to one another, and the structures are collapsible to a relative compact form for convenience of storage.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
261 words
Calf exercising and developing apparatus comprising: platform means provided by a pair of units positioned alongside one another, each unit having an independent foot-engaging surface for supporting the weight of the user of the apparatus and for distributing the weight of the user over both of the units; connecting means securing said units to one another, said connecting means including a first member extending from one of said units toward the other of said units and a second member extending from the other of said units toward said one unit, and pivot means securing said members to one another for movement about a vertical axis, whereby the foot-engaging surfaces of said units can be moved from a position disposed in parallelism with one another to positions where said foot-engaging surfaces are disposed at different lateral angles with respect to one another; brace means engageable with the floor for stabilizing said platform means; separate means associated with each unit for independently adjusting the elevational angle of the plAtform means of each unit relative to said brace means, so that each of said platform means can be moved between an initial collapsed position and a selected inclined position, whereby the slope of said foot-engaging surfaces can be varied as desired; and separate means associated with each unit for positively, yet releasably, retaining each of the platform means in the selected inclined position to provide a stable structure upon which exercises can be performed, said separate retaining means allowing the foot-engaging surfaces of said units to be positioned at different elevational angles, if desired.
Claim 2
Dependent Claim
261 words
Calf exercising and developing apparatus comprising: platform means provided by a pair of units positioned alongside one another, each unit having an independent foot-engaging surface for supporting the weight of the user of the apparatus and for distributing the weight of the user over both of the units; connecting means securing said units to one another, said connecting means including a first member extending from one of said units toward the other of said units and a second member extending from the other of said units toward said one unit, and pivot means securing said members to one another for movement about a vertical axis, whereby the foot-engaging surfaces of said units can be moved from a position disposed in parallelism with one another to positions where said foot-engaging surfaces are disposed at different lateral angles with respect to one another; brace means engageable with the floor for stabilizing said platform means; separate means associated with each unit for independently adjusting the elevational angle of the plAtform means of each unit relative to said brace means, so that each of said platform means can be moved between an initial collapsed position and a selected inclined position, whereby the slope of said foot-engaging surfaces can be varied as desired; and separate means associated with each unit for positively, yet releasably, retaining each of the platform means in the selected inclined position to provide a stable structure upon which exercises can be performed, said separate retaining means allowing the foot-engaging surfaces of said units to be positioned at different elevational angles, if desired.
Claim 3
Dependent Claim
29 words
Apparatus as set forth in claim 1 including means extending upwardly from said units providing a handgrip whereby the user of the apparatus can stabilize himself on said units.
Claim 4
Dependent Claim
45 words
Apparatus as set forth in claim 1 including means pivotally connecting said platform means to said brace means, so that said platform means and brace means can be folded relative to one another into internested relationship, whereby a compact structure is provided for storage purposes.
Claim 5
Dependent Claim
101 words
Apparatus as set forth in claim 3 in which said platform means includes a wall at each side thereof that extends downwardly from said foot-engaging surface, said brace means being defined by a U-shaped member having a central floor-engaging bight portion and spaced legs extending perpendicularly with respect to said central portion, each leg being pivotally connected to a wall of said platform means intermediate the length of the wall and each leg having a length adapted to position the central portion adjacent the end of the platform means when said platform means and brace means are folded into internested relationship.
Claim 6
Dependent Claim
85 words
Apparatus as set forth in claim 4 in which said adjusting means includes an opening in each sidewall of the platform means, a plurality of spaced openings in each leg of the brace means, each opening in one of the legs being aligned with a corresponding opening in the other of the legs, and means for impaling the openings in said legs and sidewalls when they are placed in registry, said retaining means cooperating with said impaling means to retain said impaling means in position.
Claim 7
Dependent Claim
86 words
Apparatus as set forth in claim 3 in which said platform means includes a wall at each side thereof that extends downwardly from said foot-engaging surface, said base means includes spaced-upright walls having said sidewalls pivotally connected thereto, and wherein said adjusting means includes slot means in at least one of said walls and a follower movable in said slot means to engage and support said platform means, said retaining means cooperating with said follower to return said follower at a selected position in said slot.
Claim 8
Dependent Claim
29 words
Apparatus as set forth in claim 6 wherein said retaining means includes a plurality of spaced detent surfaces in said slot means for positively locating and holding said follower.
Claim 9
Dependent Claim
22 words
Apparatus as set forth in claim 6 wherein said slot means is defined by an internal slot in at least one wall.
Claim 10
Dependent Claim
22 words
Apparatus as set fourth in claim 6 wherein said slot means is defined by aligned, identically shaped slots in said upright walls.
