Abstract
Abstract An exercise device for simulating cross-country skiing includes a plurality of longitudinally extending channel members mounted on cross frame members so as to define elongated slots in which trolleys for foot supporting members and hand engaging members can reciprocate. A control system interconnecting the foot supporting members and hand engaging members includes a main drive pulley interconnecting the foot supporting members for coordinated reciprocal movement and a secondary belt interconnecting the foot supporting members and hand engaging members so that each hand engaging member will reciprocate in an opposite direction to its associated foot supporting member and at a speed of twice that of the foot supporting member. A resistance structure is provided for resisting movement of the trolleys to provide a selected level of exercise.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
229 words
An exercise apparatus comprising in combination: a frame, a pair of foot supporting members, slidably mounted on said frame for linear reciprocating movement, each foot supporting member having a first idler pulley thereon, a pair of hand engaging members slidably mounted on said frame for linear reciprocating movement in parallel relationship with the movement of said foot supporting members, and a control system operably interconnecting said foot supporting members and said hand engaging members, said control system including a drive pulley mounted on said frame for reciprocal pivotal movement and a drive belt extending around said drive pulley, said drive belt having opposite ends fixed to said foot supporting members whereby movement of one foot supporting member in a first direction will cause the other foot supporting member to move simultaneously in a second opposite direction, a secondary belt having opposite ends anchored to said frame, said secondary belt being fixed to said hand engaging members for unitary movement therewith and being operably connected to said foot supporting members by frictionally passing around said first idler pulleys on the foot supporting members, and a group of second idler pulleys mounted on said framework around which said secondary belt extends whereby linear reciprocating movement of said foot supporting members causes said hand engaging members to reciprocate at a linear speed of approximately twice the speed of said foot supporting members.
Claim 2
Dependent Claim
229 words
An exercise apparatus comprising in combination: a frame, a pair of foot supporting members, slidably mounted on said frame for linear reciprocating movement, each foot supporting member having a first idler pulley thereon, a pair of hand engaging members slidably mounted on said frame for linear reciprocating movement in parallel relationship with the movement of said foot supporting members, and a control system operably interconnecting said foot supporting members and said hand engaging members, said control system including a drive pulley mounted on said frame for reciprocal pivotal movement and a drive belt extending around said drive pulley, said drive belt having opposite ends fixed to said foot supporting members whereby movement of one foot supporting member in a first direction will cause the other foot supporting member to move simultaneously in a second opposite direction, a secondary belt having opposite ends anchored to said frame, said secondary belt being fixed to said hand engaging members for unitary movement therewith and being operably connected to said foot supporting members by frictionally passing around said first idler pulleys on the foot supporting members, and a group of second idler pulleys mounted on said framework around which said secondary belt extends whereby linear reciprocating movement of said foot supporting members causes said hand engaging members to reciprocate at a linear speed of approximately twice the speed of said foot supporting members.
Claim 3
Dependent Claim
53 words
The exercise apparatus of claim 1 further including a flywheel mounted on said frame, a mechanical rectifier mounted on said frame and being operably interconnected with said drive pulley, and a flywheel belt interconnecting said rectifier with the flywheel whereby pivotal reciprocal movement of said drive pulley causes unidirectional rotation of said flywheel.
Claim 4
Dependent Claim
74 words
The exercise apparatus of claim 1 further including a resistance pulley rotatably mounted on said frame, adjustment means for selectively and variably restricting the rotation of said resistance pulley, a mechanical rectifier mounted on said frame and being operably interconnected with said drive pulley, and a resistance belt interconnecting said rectifier with the resistance pulley whereby a varied resistance to rotation can be imparted to said drive pulley by selectively varying the adjustment means.
Claim 5
Dependent Claim
74 words
The exercise apparatus of claim 2 further including a resistance pulley rotatably mounted on said frame, adjustment means for selectively and variably restricting the rotation of said resistance pulley, a mechanical rectifier mounted on said frame and being operably interconnected with said drive pulley, and a resistance belt interconnecting said rectifier with the resistance pulley whereby a varied resistance to rotation can be imparted to said drive pulley by selectively varying the adjustment means.
Claim 6
Dependent Claim
15 words
The exercise apparatus of claim 3 wherein said adjustment means is a variable electronic brake.
Claim 7
Dependent Claim
100 words
The exercise apparatus of claim 1 wherein said frame is of generally rectangular configuration defining a first end and a second end, said drive pulley being disposed adjacent to said first end and wherein said group of second idler pulleys includes a pulley on either side of said drive pulley at said first end in alignment with the linear movement of said hand engaging members, a pair of pulleys at said second end in alignment with the linear movement of said hand engaging members and a pair of pulleys at said second end in alignment with said foot supporting members.
Claim 8
Dependent Claim
33 words
The exercise apparatus of claim 6 wherein said ends of the secondary belt are anchored to the frame at a location between said second end of the frame and said foot supporting members.
Claim 9
Dependent Claim
42 words
The exercise apparatus of claim 7 wherein said frame includes a plurality of longitudinally extending channel members defining slots therebetween and being interconnected by a plurality of cross frame members, said channel members supporting said foot supporting members and hand engaging members.
Claim 10
Dependent Claim
28 words
The exercise apparatus of claim 8 wherein said foot supporting members and hand engaging members include wheels adapted to roll in and be guided by said channel members.
Claim 11
Dependent Claim
44 words
The exercise apparatus of claim 4 further including rotative movement detecting means associated with said resistance pulley, said detecting means being adapted to sense and display information relative to the speed at which the foot supporting members and hand engaging members are being moved.

The exercise apparatus of claim 10 wherein said detecting means is electronic.
Claim 13
Dependent Claim
132 words
An exercise apparatus comprising in combination: a frame, a pair of foot-supporting members slidably mounted on said frame for linear reciprocating movement, a pair of hand-engaging members slidably mounted on said frame for linear reciprocating movement in parallel relationship with the movement of said foot-supporting members, and a control system operably interconnecting said foot supporting members and said hand-engaging members, aid control system including a drive belt having opposite ends fixed to said foot supporting members whereby movement of one foot-supporting member in a first direction will cause the other foot-supporting member in a first direction will cause the other foot-supporting member to move simultaneously in a second opposite direction, and a secondary belt having opposite ends anchored to said frame and being fixed to said hand-engaging members for unitary movement therewith.
