Exercise machine
An exercise machine has a base housing and a boom that extends from a proximal end to a distal end. The boom is able to pivot between a rowing configuration wherein the boom is generally horizontal, and a skiing configuration wherein the boom is generally vertical. A rowing assembly includes a row handle attached to a row chain which extends into the base housing, to a row recoil device. A ski assembly includes a pair of ski handles, each ski handle being attached to a ski rope which extends into the base housing, to a ski recoil device. A transmission system has a shaft that is operably connected to a resistance device, the shaft having a row sprocket and a pair of ski spools, and the respective cables contact the spools so that movement of one of the cables rotates the respective spool, thereby rotating the shaft.
1. An exercise machine comprising:
a base housing;
a boom having an elongate rigid body that extends from a proximal end of the boom to a distal end of the boom;
a pivot mount which pivotally mounts the proximal end of the boom on the base housing such that the boom is able to pivot with respect to the base housing between a rowing configuration wherein the boom is generally horizontal, and a skiing configuration wherein the boom is generally vertical;
a seat element which is slidably mounted on the boom;
a rowing assembly that includes a row handle attached to a proximal end of a row chain which extends into the base housing;
a ski assembly that includes a pair of ski handles, each ski handle being attached to a proximal end of a ski rope which extends around at least one guide pulley, such that a distal end of the ski rope extends into the base housing;
a resistance device; and
a transmission system within the base housing that connects the ski ropes and the row chain to the resistance device, the transmission system comprising:
a shaft that is operably connected to the resistance device, the shaft having a row sprocket and a pair of ski spools;
wherein each of the ski ropes contacts one of the pair of ski spools so that movement of the ski rope rotates the ski spool, respectively, thereby rotating the shaft; and
wherein the row chain contacts the row sprocket so that movement of the row chain rotates the row sprocket, thereby rotating the shaft.
2. The exercise machine of claim 1 , wherein the row sprocket and the pair of ski spools are respectively mounted upon one-way bearings on the shaft.
3. The exercise machine of claim 2 , wherein the one-way bearing of the row sprocket operates in a same direction as the one-way bearing of each of the pair of ski spools.
4. The exercise machine of claim 1 , wherein each of the pair of ski spools is in the form of a cylinder around which the respective ski rope is wrapped.
5. The exercise machine of claim 1 , wherein the row sprocket is in the form of a sprocket, and the row chain is in the form of a chain that operatively engages the row sprocket, and extends to a row recoil device.
6. The exercise machine of claim 1 , wherein the resistance device is in the form of an air displacement fan.
7. The exercise machine of claim 5 , wherein the row recoil device is in the form of an elastic cord.
8. The exercise machine of claim 1 , wherein the boom further includes a pair of foot engagement structures for receiving feet of a user while the user performs rowing exercises.
9. The exercise machine of claim 1 , wherein a handle receiver is mounted on the base housing to catch and hold the row handle while not in use.
10. The exercise machine of claim 1 , further comprising a computer display for displaying feedback or entertainment.
11. The exercise machine of claim 10 , wherein the computer display is adjustably mounted on an adjustable arm.
12. An exercise machine comprising:
a base housing;
a boom having an elongate rigid body that extends from a proximal end of the boom to a distal end of the boom;
a pivot mount which pivotally mounts the proximal end of the boom on the base housing such that the boom is able to pivot with respect to the base housing between a rowing configuration wherein the boom is generally horizontal, and a skiing configuration wherein the boom is generally vertical;
a seat element which is slidably mounted on the boom;
a rowing assembly that includes a row handle attached to a proximal end of a row chain which extends into the base housing, wherein a distal end of the row chain is operatively engaged with a row recoil device;
a ski assembly that includes a pair of ski handles, each ski handle being attached to a proximal end of a ski rope which extends through a ski handle stop at a distal end of the base housing, around at least one guide pulley, such that a distal end of the ski rope extends into the base housing;
a resistance device; and
a transmission system within the base housing that connects the ski rope and the row chain to the resistance device, the transmission system comprising:
a shaft that is operably connected to the resistance device, the shaft having a row sprocket and a pair of ski spools, wherein the row sprocket and the pair of ski spools are respectively mounted upon one-way bearings on the shaft;
wherein each of the ski ropes contacts one of the pair of ski spools so that movement of the ski rope rotates the ski spool, respectively, thereby rotating the shaft, and wherein the distal end of each of the ski ropes is operatively attached to a ski recoil device; and
wherein the row chain contacts the row sprocket so that movement of the row chain rotates the row sprocket, thereby rotating the shaft.
