Strength training device

Technical area

The invention relates to a strength training device such as that used to strengthen the muscles in the upper body area and / or the leg or trunk muscles

Used by exercisers. The strength training device can be used in sports studios as well as, for example, in the home or other environments.

State of the art

From WO 2018/010839 A1, in connection with a device body for a strength training device, a strength training device has become known which is characterized in that it can be used for different purposes by an optional arrangement of axes within the device body, i.e. for training different body muscle groups, can be used. For example, such strength training devices are used to strengthen the chest or

Shoulder muscles and are designed in the form of a so-called chest press or a so-called shoulder press. For example, a strength training device in the form of a chest press under the designation “M5” has become known through the company eGym, which has the features of the preamble of claim 1 (https://egym.com/de/fitnessgeraete/brustpresse/).

Such strength training devices known from the prior art are characterized in that they are essentially only designed or suitable for training a specific muscle group. If several muscle groups are to be trained, a separate strength training device is required for each muscle group. Disclosure of the invention

The strength training device according to the invention with the features of claim 1 has the advantage that it is suitable at least for the selective training of at least two different muscle groups. It is therefore not necessary to use a separate strength training device for each of the muscle groups. In particular, it is intended by means of the inventive

Strength training device to replace two training devices that are designed in the sense of a chest press or shoulder press.

The invention is based on the idea of being able to use a lever mechanism that has been modified compared to the prior art, optionally for training different muscle groups. It has been found that the modification required for this is relatively simple

can be designed so that the costs or the constructive (additional)

Effort for the strength training device according to the invention compared to a

Strength training device, which is only used to train a single muscle group, are relatively small.

Against this background, it proposes the teaching of the invention according to

Claim 1 proposes to modify a strength training device known from the prior art in that the at least one second articulated lever of the lever mechanism is connected to the second axis via a coupling member, and that the two axes can each be individually locked and in operative connection with the at least one , the resistance to the movement of the axis generating unit can be connected. In other words, this means that by locking one or the other axis, the operating or grip element that can be manually operated by the trainee can be moved differently, whereby the different muscle groups can be trained in the desired manner.

Advantageous further developments of the strength training device according to the invention are listed in the subclaims. In order to achieve a particularly compact design of the lever mechanism

enable, it is in a structurally preferred embodiment of the

Strength training device provided that the at least two articulated levers are arranged on the same side of a rod of the operating element (i.e. for example in the direction of a stand side of the strength training device).

As already mentioned above, by alternately locking one or the other axis of the lever mechanism, it is possible to train different muscle groups. Typically it is used for training

different muscle groups required to move the control or grip element by the trainee in different ways. A further embodiment of the invention therefore proposes that when the first axis is blocked, the handle element is arranged pivotably about the second joint, and that when the second axis is blocked, the handle element is arranged to be approximately linearly movable. Through these two

Different types of movement of the grip element can be used to train the corresponding muscle groups separately, as in a chest press or shoulder press.

In connection with the structural arrangement of the individual elements of the joint mechanism, it is provided that, when the first axis is blocked, the coupling element is optionally on the side facing away from or facing the first axis, and when the second axis is blocked, the coupling element on the side facing the first axis Side is arranged. As a result, on the one hand the pivoting movement of the grip element and on the other hand its linear movement can be realized in a particularly simple manner.

In order to initiate or transfer the corresponding resistances to the movement of the trainee in the respectively unlocked axle, a first structural embodiment provides that the two axles are each connected to a separate unit (as a resistance source). Such a constructive training has the advantage that none

Coupling device or similar elements must be present in order, if a single unit is present, this with the two

to be able to bring different axes into operative connection alternately. In a design alternative to this proposal, it can be provided that the two axes are connected to a common unit (as a resistance source), which can be coupled to the first or the second axis via a coupling device.

In order to be able to use the strength training device described so far for training more than two different muscle groups, a further advantageous embodiment of the invention provides that at least one in

Operational connection is provided with a resistance-generating additional unit connected axis, which is connected to an additional control element via additional articulated levers, and that a neutral position of the axis is adjustable in at least two different angular positions of the additional articulated lever. Such a configuration of the

Weight training machine, for example, allows both the

To be able to train the thigh muscles as well as the abdominal muscles or back muscles according to the different neutral positions of the joint levers.

For example, to be able to put the strength training device in a corner of a room and still be able to use the strength training device

To be able to train muscle groups, it is provided in a further embodiment of the strength training device that the resistance or

Aggregates coupled axes run parallel to each other.

For training the shoulder or chest muscles mentioned as an example, as well as the back or abdominal muscles, different seating or positions of the person exercising are typically required. In a further preferred embodiment of the strength training device, which even enables the strength training device to be used by two different exercisers at the same time, as is typically conceivable in a sports studio, it is provided that the control element and the additional control element are arranged parallel and laterally offset to one another are.

Finally, a preferred embodiment of the strength training device has a

Housing in which at least the units generating the resistances are arranged within the housing, and wherein the operating element is aligned outside the housing with a plane of symmetry of the housing. As a result, tilting moments etc. on the strength training device when introducing forces or moments into the controls is minimized.

Further advantages, features and details of the invention emerge from the following description of preferred exemplary embodiments and with reference to the drawings.

Embodiments of the invention

The same elements or elements with the same function are provided with the same reference numbers in the figures.

1 shows a multifunctional strength training device 10 which is designed to be able to perform different exercises for training different muscle groups of a trainee 1. The

Strength training device 10 comprises a housing 12 with a plane of symmetry 14 which runs parallel to the two side walls 16 of the housing 12.

According to the illustration in FIGS. 1 to 5, the strength training device 10 has a lever mechanism 20 which serves to strengthen chest muscles as well as shoulder muscles and upper back muscles of a trainee 1 shown symbolically only in FIGS. 4 to 9. For this purpose, the lever mechanism 20 comprises a first axis 21 and a second axis 22, which are arranged parallel to one another, with the first axis 21 (somewhat) above the second axis 22 on the basis of the illustration in FIG

Housing 12 is arranged.

On both sides outside the housing 12 and symmetrically to the plane of symmetry 14, the first axis 22 is connected to a first articulated lever 25, the connection between the first articulated lever 25 and the first axis 21 being non-rotatable or rigid. On the side of the first articulated lever 25 facing away from the first axis 21 are the first two

Articulated lever 25 coupled to a first joint 26 in each case. The two first joints 26 are also coupled to two rods 28 of an operating element 30 that are arranged parallel to one another. As a result, the rods 28 are each arranged in the region of the first joint 26 so that they can pivot relative to the first joint lever 25. On the side of the rods 28 facing away from the first joint 26, these are connected to a common element 31 which runs transversely to the direction of the two rods 28 and which serves as a grip element 32 via which the Exercisee 1 can move the lever mechanism 20. The operating element 30 can alternatively be designed with two or more separate handle elements 32.

In an area between the first joint 26 and the grip element 32, a second joint 35 is arranged in the area of the two rods 28, via which a second joint lever 36 is pivotably attached. On the side of the second articulated lever 36 facing away from the second articulation 35, an exemplary rod-shaped coupling member 38 can be pivoted on the one hand to the second articulated lever 36, and on the other hand to the second axis 22, via a third articulation 37.

The two axes 21, 22 of the strength training device 10 are alternately either movable or rotatable or lockable or rigid, as an alternative to the lockable or rigid arrangement, pivotable through a small angle. With a view to FIG. 2, in a first embodiment it is explained that the first axle 21 is arranged or connected in operative connection with a first unit 41 and the second axle 22 in operative connection with a second unit 42. The two units 41, 42 are as

electromotive components, for example in the form of a

permanent magnet synchronous motor, and serve to counteract a rotation of the axis 21, 22 by a movement of the lever mechanism 20 by the trainee 1, against which the trainee 1 has to apply a force or torque to rotate the first axis 21 or second axis 22 to effect. Furthermore, the two axes 21, 22 are each connected to a locking device 43, 44, which, however, instead of acting as a lock, possibly also allows a rotation by a small angle, for example an angle of maximum 30 ° of the corresponding axis 21, 22.

In Fig. 3, on the other hand, the case is shown that the two axes 21,

22 with a common unit 39 via alternately switchable

Coupling devices 40 is connected.

The control of both the units 39, 41, 42 and both

Locking devices 43, 44 take place purely by way of example via a common Control device 50. The control device 50 is again connected by way of example to an input unit 52, which is only shown in FIGS. 2 and 3, and to a display 54. Via the input unit 52, from the

1 different programs or resistances of the two axes 21, 22 or the units 39, 41, 42 can be selected. The settings can be displayed, for example, on the display 54, as well as the correct execution of the movements of the trainee 1. For this purpose, it is also provided that the units 39, 41, 42 or the two axes 21,

22 with appropriate sensor devices for detecting the

Angular velocity or rotation or position are connected.

It is essential in the embodiment according to FIG. 2 that in a

Activation of the first unit 41 or the first axle 21, at the same time, the second axle 22 is locked by means of the corresponding locking device 44. Conversely, when the second axle 22 or the second unit 42 is activated, the first axle 21 is blocked by activating the blocking device 43.

Based on the sequence of figures 4a to 4c, the functioning of the

Lever mechanism 20 for training different muscle groups explained using a so-called chest press, which is used to strengthen the chest muscles of the trainee 1. Here the trainee 1 sits on one

In particular, the height-adjustable seat 2. Starting from FIG. 4a, the trainee 1 extends his arms 3 away from him from a position near his chest in such a way that they are at least approximately in the extended state according to FIG. 4c. The trainee 1 grasps the grip element 32 of the first with his hands

Lever mechanism 20. Based on the sequence of figures in FIGS. 4a to 4c, it can be seen that the second axis 22 is locked, while the first axis 21 opposes the movement of the trainee 1 via the first unit 41 with a resistance that is counterclockwise in the direction of the arrow 55 runs. It can also be seen that the two rods 28 or the grip element 32 move at least approximately in a horizontal direction according to the arrow 56 during exercise. In addition, it is mentioned that FIG. 4d shows the state in which the exercising person 1 executes a rowing movement in which the grip element 32 is pulled towards himself from a position remote from the exercising person 1. In this case, the correspondingly adjustable seat 2 or its seat back 4 serves in particular to support the chest of the person exercising 1. Furthermore, the first unit 41 acts on the first axle 21

Resistance against the direction of arrow 56, i.e. counterclockwise, generated.

5a to 5d, the strength training device 10 is used to train the shoulder muscles of the trainee 1. For this purpose, the first axle 21 is blocked via the locking device 43, while the second axle 22 is arranged in operative connection with the second unit 42. In FIGS. 5a to 5c, the case is shown in which the trainee 1 pushes the grip element 32 upwards from a position approximately at shoulder height. The two rods 28 move around the first joint 26 in the direction of the arrow 58. Via the second unit 42 or the second axis 22 there is a clockwise resistance in the direction of the arrow 57, against which the trainee 1 when his arms 3 are raised must exert a force.

In FIG. 5d, the case is shown in which the trainee 1 has to pull down the operating element 30 from a pivoted or raised position in the direction of arrow 59 in order to strengthen his upper back muscles. For this purpose, for example, the thigh area of the trainee 1 can be fixed by means of a support element 60 in the form of a support roller. In this case, too, the first axle 21 is locked and the second axle 22 is operatively connected to the second unit 42, the second unit 42 generating a counterclockwise resistance to the lowering of the operating element 30 by the trainee 1 in the direction of the arrow 61 .

Furthermore, the strength training device 10 optionally has a third axis 63 and a fourth axis 64, which run parallel to the two axes 21, 22 and which are arranged below the two axes 21, 22 on the housing 12 as shown in FIG. 1. The two axles 63, 64 arranged at a distance from one another protrude from the same one side wall 16 of the housing 12 out and are connected to a third articulated lever 65 and a fourth articulated lever 66, respectively, in a rotating manner. Parallel to the axes 63, 64, the articulated levers 65, 66 are connected on the side facing away from the axis 63, 64 to a respective pressure roller 68, 69 which acts as an operating element and which extends over the entire width of a further seat 5. The further seat 5, like the seat 2, is at least adjustable in height and is located laterally on the housing 12 and laterally offset from the seat 2.

According to FIGS. 2 and 3, the two axles 63, 64 are coupled, for example, to a separate third and fourth unit 71, 72 (analogous to units 41, 42) and a locking device 73, 74. The

Units 71, 72 and the blocking devices 73, 74 can also be controlled by the control device 50, purely by way of example. There are also correspondingly available measuring devices for detecting the position and / or

Angular speed of rotation of the third and fourth axes 63, 64 provided (not shown).

As shown in FIGS. 6 and 7, the third unit 71 or the pressure roller 68 of a first angular position of the third articulated lever 65 in conjunction with an adapted position of a further seat 5 can serve to strengthen the thigh muscles of the exerciser 1. 6 shows the case in which the trainee 1 is in contact with the pressure roller 68 with his feet, in such a way that he moves the third articulated lever 65 from a neutral position around the third axis 63 counterclockwise according to the direction of the Arrow 75 must move, against this direction of movement the third unit 71 applies a resistance. The fourth unit 72 is inactive and the pressure roller 69 is in a position that does not hinder the trainee 1 in moving the pressure roller 65.

In contrast, FIG. 7 shows the case in which the trainee 1 has to move the third articulated lever 65 or the pressure roller 68 with his feet or legs from a neutral position clockwise in the direction of the arrow 76, the third unit 71 also creates a resistance against this movement. If necessary, the pressure roller 69 can be locked in a position in this exercise that the

Prevent the thighs of trainee 1 from lifting off the seat 5. Finally, in FIGS. 8 and 9, exercises to strengthen the abdominal or

The back muscles of the exerciser 1 are shown. Here is the fourth

Unit 72 activated and the third unit 71 in a passive or

locked state in order to support the legs or feet of the

To serve trainee 1. In Fig. 8, the trainee 1 must

Move counterclockwise according to arrow 77. On the other hand, the trainer 1 in FIG. 9 must hold the pressure roller 69 with his back

Move clockwise in the direction of arrow 78.

In addition, it is mentioned that the laterally offset arrangement of the two seats 2 and 5 also makes it possible for two exercisers 1 to do the

Can use strength training device 10 at the same time. To this end, appropriately modified control devices 50 or input units 52 and displays 54 may be required.

Because the upper body workout and the lower body workout are not at the same time

must take place, it is also possible to use the same units / drives

41, 42, which are used for the axes 21, 22, also for the axes 63, 64 to be used. For this purpose, the units 41, 42 can be combined with special gear designs, which then couple the axes 63, 64 with the mechanical resistance generated by the units 41, 42. For example, a so-called Maltese cross gear (geneva drive) or a star wheel mechanism (star wheel mechanism) can be used as the gear design. The resistance (the braking torque) is transmitted from the units 41, 42 optionally to the axes 21, 22 and / or to the axes 63, 64. Thus, in particular up to four axes 21, 22, 63, 64 can be coupled with a single unit 41 or with a total of exactly two units 41, 42 for the transmission of a mechanical resistance or a braking torque.

The strength training device 10 described so far can be modified or modified in many ways without departing from the concept of the invention

to deviate.
