Abstract

According to the invention, fitness machines are provided with the following: two pivotable levers, one of which can be moved with the chest and the other by the legs; a coupler for both levers, and a seat which is moved when the levers move by means of a coupling thereto.

Description

Fitness machine

The invention relates to a machine in which two levers against the resistance of weights are simultaneously moved by the athlete or patient.

One lever of both levers is pivoted with the upper body against the resistance of movable weights. This is usually done by providing this lever with a backrest and with extensions that have handles at the ends. The athlete or patient sits on a seat, leans against the backrest and moves the lever by gripping the pivoting lever with his hands overhead and moving / pivoting the upper body.

The other lever of the two levers is moved with the legs. This lever movement also takes place against the resistance of weights.

Both levers are linked together. The coupling causes both levers to move simultaneously. The coupling coordinates the upper body movement and the leg movement. It is known to effect coupling via a movement linkage. With some designs, it is sufficient to connect the pivotable levers with a rod in an articulated manner.

The coupling also has structural advantages: common weights can be used for both levers. The weights are usually arranged such that they can be raised and lowered in an upright guide. The athlete or patient lifts the weights under load. He pulls the weights with the levers. The lever movement is transmitted to the weights by chains or ropes or bands. The traction devices can be deflected in any direction via rollers. After reaching the end position (maximum lever deflection in each case), the weights bring the levers back to their original position.

The exercise that can be carried out in this way is referred to as a folding knife. The exercise not only strengthens the abdominal muscles but also other muscles. The coupling coordinates the upper body movement and the leg movement.

During the folding knife exercise, the body halves are moved against each other against the resistance of the weights. The athlete or patient pulls on the handles described above. The legs grip a corresponding extension of the lever.

Alternatively, the body can be stretched, even against the resistance of the weights. When you stretch your body, other muscle groups are strengthened. When stretching the body, the athlete or patient presses with one shoulder and one foot with the other lever.

Modern machines have adjustable levers and also an adjustable seat. Adjustment allows adaptation to the different body sizes of athletes and patients.

The known machines have proven themselves. Nevertheless, the invention has set itself the task of improving these machines. The invention is based on the knowledge that the load on the vertebrae associated with the exercises can be reduced. According to the invention, this is achieved by a relief movement. The relief movement is achieved according to the invention by means of a movement of the seat. The movement of the seat requires the mobility of the seat. The moveable arrangement is not new. A movable arrangement for adjusting the seat height is known. Likewise, the use of seat springs is known. However, neither is comparable to the relief movement according to the invention.

A stroke movement is performed when the body is stretched and a lowering movement is carried out with the seat during the folding knife movement. Surprisingly, the lifting movement and the lowering movement are completely different and advantageous Movement feeling than with the conventional body stretching or with the conventional folding knife movement.

The sitting movement preferably supports the stretching of the body. Preferably there is at least one full extension (upper body and legs are aligned) and a maximum of overextension (upper body and legs form an angle that is less than 180 degrees and opens downwards) of 30 degrees. With the hyperextension of 30 degrees, the described included angle is greater than or equal to 150 degrees. The hyperextension of a minimum of 5 degrees and a maximum of 15 degrees is even more preferred. The included angle is then minimally less than or equal to 175 degrees and greater than or equal to 165 degrees.

The seat movement according to the invention takes place depending on the lever movement, e.g. proportional to the lever movement. The seat movement can also be accelerated or decelerated at any point.

By moving the seat, the athletes or patients in the highly stressed areas of the resulting backbone curvature can be relieved. The highly stressed areas can be tested with the athletes or patients under low loads by checking the condition in every position. With the seat movement, the highly stressed areas can be passed through particularly quickly or particularly slowly, as desired.

The seat movement can be generated in different ways. Motion drives come into consideration, e.g. electric, pneumatic or hydraulic drives. A mechanical drive preferably takes place with a movement linkage and the movement linkage is coupled to the levers described above or to their movement linkage. If the linkage connecting the two levers

The seat movement can also be adjusted to the body size.

Among other things, this is possible in the case of the coupled movement linkage by changing the length of the lever arms occurring in the movement linkage. The connecting linkage is then optionally made telescopic in one part and can be gradually adjusted and locked. The locking can be done by bolts that are pushed through. Spring-loaded bolts that unlock against the spring force are an advantage pulled and released to lock. Different holes in the extendable connecting rod correspond to the bolts.

A coupling with the movement linkage for the seat movement preferably takes place in that a two-armed lever is mounted in the machine frame, one arm slidably engages under the seat and the other arm slidably abuts a lever arm of the connecting linkage. As a result, a movement of the connecting linkage causes a movement of the double-armed lever arm and a seat movement above it. At the same time, the sliding gripping under or sliding concerns allows a shift at the points of contact. This includes robust and inexpensive technology.

In the sense of the invention, the seat is also reached under when the double-armed lever arm engages under the guide rail of the seat with a lever. In addition, within the meaning of the invention, such levers also belong to the movement linkage, which sit together and firmly on an axis with the lever pivoted during stretching by pressing the feet together and form the sliding contact with the double-armed lever.

In the sense of the invention there is still a sliding contact if the friction is reduced by the fact that the connecting rod runs with a roller on a running surface of the double-armed lever arm or vice versa.

It is also advantageous to provide the pivotable levers with a pivot lever setting. With the swivel lever setting, the desired starting position of the swivel lever can be set without having to exert any other influence. For the

Various solutions are known for pivot lever adjustment.

One solution is based on the fact that a shaft is rotatably arranged in the machine frame. There is a disc on the shaft. On a protruding through the pane

A hollow shaft with another disk is rotatably seated. Both disks are arranged next to each other and can be coupled or uncoupled for adjustment.

The lever sits on the hollow shaft end facing away from the disk.

A driver for the traction means described above is seated on the shaft, which is rotatably mounted in the machine frame, at the end facing away from the disk. In modern machines, the driver is an eccentric, with which influence is exerted on the lever length and, moreover, on the force required to move the weights. A releasable clamp connection or a releasable plug connection is provided between the two disks. Spring-loaded bolts are again favorable for the plug connection, so that the connection can be released by pulling the bolts against the spring force and can be restored by releasing the bolts. There are corresponding holes in the washers for the bolts. One hole is sufficient in one disc. A large number of holes are provided in the other disk. The holes in one disc have the same center distance from the center of the disc as the holes in the other disc.

By connecting the discs, the torque of the swivel lever generated by the athlete or patient is transmitted to the eccentric via the shaft.

The pivot lever setting described above is preferably applied to the pivot lever that supports the backrest and the handles.

A different swivel lever setting is preferably provided for the other pivotable, foot pressure-loaded lever: a) a telescopic linkage as described above b) an articulated connection of the telescopic linkage with the described linkage c) an articulated connection of the telescopic linkage with the foot pressure-loaded pivot lever d) an otherwise freely rotatable, pressure-loaded swivel lever in its swivel bearing

The telescopic linkage is advantageously arranged in such a way that the associated adjustment bolt can be comfortably reached by the athlete or patient on the seat. It is advantageous if the adjusting bolt is gripped with one hand and the lever under pressure from the foot is held with the other hand. This prevents the lever from knocking out. The reason for the deflection is the lever weight and the off-center center of gravity. A handle on the lever is advantageous for holding the lever.

The lever described above, which carries the backrest, largely prevents the lever from swinging out when the lever is adjusted by providing the lever with a weight compensation so that the center of gravity lies in the region of the pivot axis. In addition, this lever can be prevented from swinging out using the handles described.

The weight balance can also be applied to the other lever under pressure from the foot.

Advantages also result from an articulated to the associated lever

Foot plate of the lever under pressure from the foot. Due to the flexibility of the footplate, the

The feet of the athlete or patient take the position that is most comfortable for the person.

At the same time, slipping off the footplate is prevented by the footplate being set back in the direction of the foot pressure with respect to its pivot axis. The foot pressure then automatically stabilizes the footplate. One can be sufficient

Be one centimeter away. A larger distance of 2 to 5 cm is preferably selected.

In addition, the freedom of movement of the footplate can be limited by stops.

The entry of the athlete or patient into the device is made easier by a step plate between the two swiveling levers. The tread plate can be held on the connecting linkage of both levers.

The above-mentioned lifting and lowering weights are optionally offset so that the plane of movement of the weights is at an angle to the plane of movement of the levers. On the way, advantageous designs for the machine frame / frame can be achieved. The advantageous designs include an approximately triangular, pyramid-shaped machine tower. Such a machine tower can also be realized if a belt or chain is provided as the traction means. According to the invention, the use of belts and chains as a traction device is possible if a multiple deflection, preferably with pivotable deflection rollers / wheels, is provided. Due to this design, the low lateral freedom of movement of the belts and chains is optimal exploited. In addition to the swiveling roller arrangement, the tower height can also have an influence.

In the drawing, an embodiment of the invention is shown.

1 and 2 show a machine frame which has inclined upright struts 1 and 3. The struts 1 and 4 are connected at the top by a common plate 3 and at the bottom by a 2 and 5.

Weights can be raised and lowered between the struts 1. The guide is formed by rods, not shown. The weights are so-called plug-in weights. They have a plate-like shape with two spaced holes that allow you to run on the guide rods. In addition, a central through opening for a rod and side openings are provided. The rod engages through the central through opening and is provided with a large number of plug-in holes for a bolt. The bolt is inserted into the rod at a desired weight through the side opening. If the bar is then pulled over a band 18, the “inserted” weight and all other weights positioned above this weight are raised.

The band 18 is attached to an eccentric 11. Turning the eccentric causes the weights to be lifted.

The eccentric 11 is seated on a shaft 9. The shaft 9 is rotatably arranged in the strut 4 and protrudes from the strut 4 on both sides (with both ends). The eccentric 11 is seated on one shaft end, and a releasable plug-in coupling 12 with a spring-loaded plug pin 13 is seated on the other shaft end. The plug-in coupling consists of two disks, of which one disk encompasses the other on the outer edge with a collar. The spring-loaded socket pin sits on the collar and, when connected to the other disk, engages through the collar in the outer edge of the other disk. There is a large number of evenly distributed corresponding plug holes. The plug holes have an opening width adapted to the bolt.

The other disc sits firmly on a hollow shaft, the hollow shaft in turn sits on the corresponding shaft end, which is rotatably mounted in the strut 4. At the end facing away from the plug-in coupling, the hollow shaft carries a lever 14. The lever 14 is a pivot lever with a backrest 16 and handles 17 at one end and with a balance weight 15 at the other end.

In addition to the lever 14, there is another swivel lever. The other pivot lever is formed by a pivotable frame 37. The pivotable frame 37 is held by steel cheeks 20. The pivotable frame 37 is seated on a shaft 22. The shaft 22 is held in a hub 21 which is welded to the side cheeks 20. The side cheeks 20 are in turn attached to a foot 6, 1 of the mesh frame, welded.

The hub 21 is fixed. A frame 26 with a step surface is also seated on the shaft 22. The frame 26 is pivotable. The movement is explained below.

The pivotable frame 37 carries at the free, upwardly projecting end a base plate 40 made of sheet metal, the ends of which are folded over for stiffening.

The base plate 40 is pivotally held on an extension 38 of the frame 37. The freedom of movement of the base plate 40 is limited by stops, of which the stop 39 is shown. In the exemplary embodiment, the tread surface of the foot plate 40 is at a distance of 3 cm from the center of the pivotable mounting.

The two levers described above are coupled to each other by a movable linkage. The linkage is formed by a) a lever 10 on the shaft 9 b) a rod 23 articulated to the lever 10 c) a telescopic rod 24

The connection between one end of the rod 23 and the lever 10 is by a

Joint formed.

At its other end, the rod 23 is articulated to the frame 26. The

In principle, frame 26 forms a further rod.

A hinge pin belongs to the joint between the rods 23 and 26. On the

The telescopic further rod 24 is also located in the hinge pin. The telescopic rod 24 forms a triangular, fixed, but adjustable construction with the pivotable frame 37 and the frame 26. The rod 24 forms a first rod therein, the pivotable frame 37 a second rod and the frame 26 a third

Rod.

The connecting rod 23 is articulated to this triangular construction.

The frame 26 and the connecting rod 23 and the rod 24 have a common one

Hinge that is also moved when the lever is pivoted. The frame 26 and the

Frame 24 sit on a common fixed pivot axis.

The rod 23 has a special position in relation to the lever 14 and the pivotable frame 37. The articulation points of the rod 23 with these systems describe circular arcs during the system movement. The rod 23 forms with the longitudinal axis approximately the tangent in the hinge points of these arcs. Roughly means that the deviation from the tangent deviates no more than 30 degrees, preferably no more than 10 degrees, from the exactly tangential position.

In this situation, there is only a minimal need for freedom at the articulation points, so that normal joints with normal play, possibly with a somewhat larger movement play, can be used. This includes an economically particularly favorable construction.

The telescopic rod 24 consists of two tubes which can be pushed or pulled apart. The pipes can be secured in their respective positions by means of plug pins. Corresponding openings are provided in the tubes for the plug pins. In the exemplary embodiment, a plurality of openings of the same width and the same center distance are provided in one tube. The socket pin is spring-loaded in the outer tube, so that this socket pin has the same function as the socket pin which is provided on the coupling explained above. By

Telescoping (change in length) of the rod 24, the position of the pivotable frame 38 is changed.

The rod 23 is articulated to the frame 37 at the other end, so that a movement of the lever 14 is transmitted to the pivotable frame 37 via the linkage and vice versa. A support 8 is located on the foot 6, 7 of the machine frame. A seat 33 is held on the support 8 so that it can be raised and lowered. The associated guide is formed by two sleeves and two guide rods 32.

A double-armed lever 29, which is pivotably mounted at 30, serves as the movement mechanism for lifting and lowering the seat 33. One end of the lever 29 engages under the guide rod 32. A lever with a roller 27 bears on the other end of the lever 29. The lever with the roller 27 is fixedly connected to the pivotable frame 37. For better interaction of the roller 27 with the lever 29, a tread 28 is provided on the corresponding lever arm. At the other end of the lever, a sliding surface 31 is provided, which forms the contact surface with the guide rod 32.

In the application, an athlete sits on the seat 33. Then he sets the correct starting position of the pivot lever 14 on the coupling 12, furthermore the correct starting position of the pivoting frame 37 and the desired load, which depends on the number moving plug weights results.

The athlete leans on the backrest, grips the handles 17 and braces his feet against the footplate 40, which, due to its special arrangement, assumes a stable position despite pivoting mobility.

With further effort, the athlete leads his body into a stretched position. The lever 14 and the pivotable frame 37 are pivoted. At the same time, the seat 33 rises as a result of the lever pivoting.

The dimensions of the levers are chosen so that the athlete experiences hyperextension when fully extended. The upper body and the legs form an angle between them downwards, which in the exemplary embodiment is 170 degrees.
