7 a plan view of the Kraftumlenkgetriebe after the engagement of the pinion in a right of the pinion arranged rack.

In 1 is a training device 10 with its essential components shown in perspective with removed panels and upholstery. The training device 10 has a weight tower 12 and a floor frame 14 who in 1 is illustrated with removed bottom plate. On the floor frame 14 is on a crossbeam 16 a column 18 fixed on which a seat 20 is arranged. The seat 20 is shown without padding and serves as a training person to sit, with the right side of the training person to the weight tower 12 has.

In 1 one recognizes furthermore a two-part body support 22 , without the still applied padding. The body support 22 is just like a two-piece handle part 24 on a carrier piece 26 fixed vertically and horizontally with two adjustment devices 28 . 30 is adjustable. The carrier part 26 is at one end of a swing arm 32 arranged, its second end with a training arm 34 connected is.

That from the swivel arm 32 groundbreaking end of the training arm 34 is rotatable on the cross member 16 stored and with a first sprocket 36 rotatably connected.

When the on the seat 20 sitting training person by twisting her torso through the swivel arm 32 and training arm 34 formed rotator 38 as an actuating element of the training device 10 deflects or pivots, follows the first sprocket 36 the rotational movement of the rotator 38 and transmits this rotation of the first sprocket 36 on a cable arrangement 40 , The cable arrangement 40 is in the range of the first sprocket 36 designed as a chain or toothed belt to a slip-free transmission of the rotational movement of the first sprocket 36 even under heavy load.

The cable arrangement 40 is via two lower pulleys 42 in the weight tower 12 in 1 turned 90 degrees upwards. At the in 1 upper end of the weight tower 12 there is a deflection of the cable 40 with the help of two upper pulleys 44 180 degrees down. The cable arrangement 40 is with a second sprocket 46 a Kraftumlenkgetriebes 48 engaged. The power deflection gear 48 has a sled 50 caused by rotation of the rotator 38 over the Kraftumlenkgetriebe 48 in two guide rails 52 vertically movable up and down. The guide rails 52 are with two cross members 53 connected in turn to the frame 55 of the weight tower 12 are attached.

When the force deflection gear 48 with the help of a switching handle 54 for a reversal of direction is in the engaged state, the carriage moves 50 according to the direction of the deflection of the rotator 38 in 1 up or down. The sled 50 is with a holding bar 56 coupled, through a series of training weights 58 extends. Depending on which of the side holes of the training weights a mounting pin 60 is inserted, the above the mounting pin 60 located training weights 58 according to the movement of the support rod 56 moved up and down. This movement of training weights 58 takes place under the leadership of two guide rods 62 ,

2 shows another training device 11 with its essential components without covers and with only a single training weight 58 , On the floor frame 14 of the training device 11 is on a pillar 18 a seat 20 attached, on which a training person can take place and with their extremities, for example their arms, as body supports 64 trained actuators can take this to each other or away from each other by the training weight 58 to move generated power. The body supports 64 are with two support arms 66 connected.

The two support arms 66 are each rotatable with an in 3 shown sprocket pair 68 connected. The sprocket pair 68 is similar to the first sprocket 36 of in 1 illustrated training device 10 with a cable arrangement 40 connected. The cable arrangement 40 is in the range of the sprocket pair 68 designed as a chain or toothed belt to the transmission of high tensile forces on the cable arrangement 40 on the training weights 58 to allow.

How to get in the 3 seen from below, the cable arrangement 40 over two pulleys 42 90 degrees in the longitudinal direction of the weight tower 12 diverted. In 3 you can still recognize deflection sprockets 70 indicating the course of the cable arrangement 40 favorably influence.

According to the in 1 illustrated exercise device 10 is the cable arrangement 40 at the in 2 illustrated exercise device 11 designed so that movements of the sprocket pair 68 on the second sprocket 46 be transmitted. Depending on the switching position of the Kraftumlenkgetriebes 48 then takes place when squeezing the body supports 64 lowering or raising the support rod 56 and the training weights 58 ,

At the in 4 illustrated center position of the Kraftumlenkgetriebes 48 there is no movement of the retaining rod 56 when the support arms 66 be moved back and forth by the training person.

How to get into the 4 and 5 recognizes, is the second sprocket 46 with a pinion 72 trained drive wheel coupled. The second sprocket 46 and the pinion 72 are one in the weight tower 12 fixed axis 74 rotatable, the rotation depending on the direction of movement of the cable arrangement 40 clockwise or counterclockwise. The cable arrangement 40 is along the area with the second sprocket 46 cooperates, formed as a chain.

The cable arrangement 40 may also consist entirely or partially of a toothed belt or have a continuous rope when the sprockets are suitably replaced by rollers to the the cable arrangement 40 is wrapped several times to produce a good frictional engagement.

The sled 50 of Kraftumlenkgetriebes 48 is in the weight tower 12 with the help of the two guide rails 52 attached vertically displaceable. When moving the carriage 50 along the guide rails 52 the one with the sled 50 connected holding staff 56 also moved vertically, so that according to the movement of the carriage 50 the training weights 58 be moved up or down.

At the in 4 configuration shown is the carriage 50 because of the training weights 58 generated force at the bottom of the guide rails 52 , The pinion 72 can be in Kraftumlenkgetriebe 48 rotate freely without the sled 50 to move. This remains the case as long as the person exercising the handle 54 in the in 4 illustrated middle position leaves.

The switching handle 54 is on a trapezoid frame coupling plate 78 attached to the the handle 54 opposite edge by means of a connecting element 80 as pivot axis is rotatably connected to the carriage. Near the handle 54 is in the sledge 50 a slot 82 provided in the one on the coupling plate 78 attached guide pin 88 protrudes and so the swivel angle of the clutch plate 78 limited.

The handle 54 are three detent holes 86 assigned. The switching handle 54 can be against a spring force away from the clutch plate 78 to be pulled. This is a locking pin 84 from the middle detent hole 86 pulled out so that the coupling plate guided by the guide pin 88 from the in 4 shown positioning is pivoted to the left or to the right.

If starting from the in 4 shown positioning after pulling the handle 54 the locking pin 84 disengages and pivoting the coupling plate 78 counterclockwise and the handle 54 finally with its locking pin 84 in the 4 rightmost illustrated Rastungsloch 86 comes to rest, results in the 5 illustrated configuration in which the pinion 72 with one left of the pinion 72 arranged left rack 90 engages.

The coupling plate 78 is with a trapezoidal recess 92 provided on the left side of the left rack 90 and on the right side of the right rack 94 is limited. The racks 90 . 94 form coupling elements that allow the weight of the training weights 58 optionally in a left-handed or right-handed torque on the cable arrangement 40 implement. The longitudinal axes of the racks 90 . 94 make a sharp angle.

The sled 50 has an opening 96 that allows the sled 50 opposite the pinion 72 in the weight tower 12 is fixed to move.

When the training person of the training device 10 or the training device 11 will perform the intended exercises, the control handle 54 first in the in 4 shown middle position pivoted and locked. Since now no coupling of Kraftumlenkgetriebes 48 with the training weights 58 is present, the training person without effort the training arm 34 of the training device 10 or the support arms 66 of the training device 11 bring into any starting position, from which a force-claiming movement is to take place.

Once the exercising person on the seat 20 Has taken place, it can handle the handle in one-handed operation in comfortable operating height 54 grab and get out of the exerciser 10 . 11 get out of or leave the position out of their training position if they choose the shift handle 54 to the left or to the right from the in 4 illustrated neutral position for the simple Entry and exit swiveled.

Will the shift handle 54 pulled and after pivoting the coupling plate 78 counterclockwise in the right detent hole 86 engages, there is a engagement of the pinion 72 in the upper area of the left rack 90 , From this point on it is possible for the training person to turn the pinion 72 clockwise and thereby over the retaining bar 56 the training weights 58 to lift.

When the exerciser after the Kraftumlenkgetriebs 48 performs a movement, rotates at a corresponding direction of movement of the training person, the pinion 72 in a clockwise direction, allowing the slide 50 to the in 6 shown upper end position can be moved while doing the training weights 58 be raised. The required force depends on the existing gear ratios, which are constructive and allow optimal weight gradations.

When the training person the shift handle 54 , as in 7 shown, pivoted in the clockwise direction and can engage, comes the pinion 72 with the right rack 94 engaged. Because the right rack 94 on the left rack 90 opposite side with the pinion 72 it is for lifting the training weights 58 and moving the carriage 50 against the gravity of the training weights 58 necessary to reverse the direction of exercise movement.

This means for the exercising person that they are moving, depending on which direction of the training arm 34 or the support arms 66 to be done under load, in a simple way, the left or right pivot position of the handle 54 chooses.

After the end of training, the exerciser can use the control handle 54 from comfortable operating height and out of their training position, without getting out of the training device or leaving their position, bring them back into the middle neutral position. It is then possible, the swivel arm 32 of the training device 10 or the body supports 64 of the training device 11 without any effort to move so that a simple exit from the training device 10 or 11 is possible.
