Description

The invention relates to a training device for muscle training. It relates to a training device which is designed to apply a load designed as a compressive force or a tensile force to a person exercising who is using the training device for this purpose. The respective load acts on the shoulders or arms of the exercising person via a dumbbell bar carried on the shoulders or held with the hands, which forms an essential component of the training device. Muscle training for persons undergoing rehabilitation treatment is viewed as a preferred purpose of the training device as claimed and described below, without, however, restricting the invention and / or its use. Rather, the training device according to the invention can be used equally for rehabilitative as well as for athletic muscle training, in particular for fitness goals.

Dumbbell training is a widespread form of training for the aforementioned purposes, i.e. for rehabilitative or athletic muscle training trained. By means of weights, preferably arranged on both sides of a barbell, a pressure force is exerted on a person exercising, carrying the barbell on their shoulders or holding it with their hands, which the person can counteract by stretching their arms and thus lifting the dumbbell weight to train their arm muscles. It is also possible to lift the dumbbell weight from a crouch by stretching the legs or from a bent position by straightening the trunk and thereby training the leg muscles or the trunk and back muscles.

Further possibilities of muscle training using a dumbbell bar are given by imparting a force opposing the exerted tensile force to a person holding the dumbbell bar and exerting a tensile force on it. Here it is known to connect the dumbbell bar on both sides with ropes or belts, via which the aforementioned force, which counteracts the tensile force exerted by the person exercising on the dumbbell bar, is imparted to the dumbbell bar. For this purpose, the ropes or belts connected to the barbell are guided over rollers, with their other ends facing away from the barbell being connected to a weight, a spring or to at least one drive which in turn exerts a tensile force.

Training devices of the aforementioned type are typically used in a stationary operation in which the training person carries out the respective exercises to a certain extent on the spot, that is, without moving in a running / walking manner. In the last-described case of training by exerting a tensile force on the dumbbell, this is usually the result of the typically fixed arrangement of rollers over which the ropes or belts connected to the dumbbell are guided, as well as the fixed arrangement of the corresponding counterforce Middle.

In the case of lifting movements performed using a dumbbell weight, the typically stationary execution of corresponding exercises is determined in particular by safety regulations to avoid accidents. It is common here to take the dumbbell weight at the respective training place from a safety storage holder and to carry out the exercises in the immediate vicinity of this storage holder and to put the bar with weights back into the storage holder upon completion. Due to the safety regulations mentioned, it is also common for the exercises to be secured by an assistant by raising and lowering the weight-loaded barbell several times.

In training and fitness centers, the athletes usually help each other. However, this is usually not possible in the rehabilitation sector, i.e. in the event that several people in rehabilitation are training at the same time. It is rather the case that a therapist, i.e. staff, is required for each person exercising, on the one hand to give instructions for the training and on the other hand to secure the exercises under the safety aspect already mentioned. In view of the fact that a person supervising a corresponding rehab training could easily instruct several training people at the same time, it is desirable, among other things, from the point of view of saving personnel costs, that not every training person has a person who secures the training exercises in compliance with the safety regulations must be set aside.

Some solutions have already become known for solving the problem addressed above. For example, this is done in the DE 39 36 377 A1 a solution is described in which ropes are attached to the dumbbell bar loaded with weights at the ends, which are guided over pulleys arranged on horizontally extending support arms of a vertically rising stand and with their other ends on a slide that can be moved vertically up and down along the stand are attached. Via means that can be operated electrically by the person exercising, a pretensioned bolt can also be released, which slides into a bore of several bores formed in close vertical succession on the stand and thus fixes the dumbbell bar in its current vertical position to end the training.

the DE 40 11 131 A1 discloses an exercise device in which straps are attached near both ends of the weighted barbell. The belts can be rolled up on winding drums which are rotatably mounted on a winding shaft arranged on a frame above the head of the exercising person. By means of an electric drive, a toothed pulley arranged in a torsionally rigid manner in the center of the winding shaft and a toothed belt guided over the drive shaft and the toothed pulley, the belts are always kept taut unnoticed by the person exercising and the weight-loaded dumbbell bar is secured. A similar solution working with hydraulics is provided by the EP 0 678 312 A1 in relation to a weight bench for lying down training.

Also from the WO 2016/126254 A1 a solution has become known, which is supposed to make it unnecessary to provide a person who provides assistance to a person who does dumbbell training. According to the solution described, the dumbbell bar rests in the region of its two ends, but on the inside of the respective weight arranged at the very end, on a strut (cross brace) arranged horizontally and transversely to the dumbbell bar. The dumbbell bar is fixed to the two cross struts via a bearing arrangement formed by a pivot bearing and a sliding bearing. The bearing arrangement makes it possible, on the one hand, to move the dumbbell bar in the horizontal direction along the cross struts and, on the other hand, to perform pivoting movements. The two cross struts carrying the dumbbell bar are in turn fixed at their two ends via a slide bearing on each of a vertical guide rod. The dumbbell bar also has at least one brake that can be actuated with the aid of a lever, so that the dumbbell bar can be safely moved upwards or downwards along the guide rods.

The solutions described above have in common that they increase the safety of a person exercising, so that, if necessary, additional assistance from another person can be dispensed with. However, all of the solutions in the cited publications are training devices on which the respective exercises are carried out in a stationary manner. A person exercising on the equipment can basically not move from the place with the weight-loaded barbell, but rather carries out their exercises in place. The training devices are also designed to train essentially only the arm muscles and muscles of the upper torso that are typically trained when lifting weights, so that they can only be used flexibly to a limited extent with regard to the existing training options.

The object of the invention is to provide a training device which enables a person to perform training exercises using a dumbbell bar imparting a compressive force or a tensile force, without necessarily having to rely on the assistance of another to ensure a high degree of accident safety is only required for people who take care of them. In addition, the corresponding training device should be designed in such a way that each training person has a high degree of freedom of movement when performing the exercises and, if necessary, in addition to the usual training of the arms, including the upper torso area, the simultaneous training of a large number of other muscle groups , such as muscles of the lower and lateral trunk area, the pelvic area and / or the legs, including their lower legs, and in particular a training of the coordination ability with a simultaneous training of the aforementioned muscle groups. In particular, the training person should be able to move largely freely within a training room.

The object is achieved by a training device with the features of claim 1. Advantageous designs and developments of the invention are given by the subclaims.

Essential components of the training device for rehabilitative or athletic muscle training proposed to solve the problem are a device carrier and a dumbbell bar held on this device carrier by means of ropes or belts guided over pulleys. Via the aforementioned ropes or belts, the dumbbell bar is brought into operative connection with at least one means (explanations on the nature of this at least one means will be given later) for the formation of a load acting on a person exercising as a compressive force or a tensile force. With regard to the aforementioned roles, at this point and in the following and in the claims, rope pulleys should always be used, regardless of whether the dumbbell bar is held on the device carrier by ropes or straps.

According to the invention, the device support consists of a base support and a functional support connected to the base support via a pivot bearing or a turntable, wherein the base support can be moved in a horizontal plane along a traverse arranged above the person exercising. The functional carrier, on which the pulleys for the ropes or belts holding the barbell are arranged, can be rotated about a vertical axis relative to the basic carrier due to its connection with the base carrier via the pivot bearing or the slewing ring.

According to a first embodiment of the invention, the at least one means already mentioned, which is brought into operative connection with the dumbbell bar to apply a load to the exercising person, is weight pieces that exert a compressive force and are arranged at the ends of the dumbbell bar on both sides. In the embodiment in question, the training device, more precisely its device carrier (in particular the function carrier) is designed in such a way that when the dumbbell bar is lifted by the exertion of a lifting force exceeding the weight of the dumbbell bar with the weights, the ropes or belts on the function carrier of the Device carrier arranged pulleys are rolled up.

The aforementioned lifting force causing the lifting of the dumbbell bar is of course applied by a training person using the device when the training device is in practical use. The embodiment can also be designed so that the ropes or belts are pretensioned to compensate for the weight caused by the barbell itself, that is, to compensate for the weight force caused by the barbell without weights. As a result, at least the dumbbell bar, as long as no weights are arranged on it, is held in suspension to a certain extent by means of the ropes or belts.

According to a particularly advantageous development of the above-described first embodiment of the training device according to the invention, which is designed to apply a weight force (pressure force) to the exercising person, this is equipped with a fall brake which, when the dumbbell bar moves downwards, in the event that a maximum rolling acceleration is exceeded , the unwinding of at least one of the ropes or belts from the associated pulley is blocked. Such a fall brake can function with regard to the blocking of the unwinding of a rope or belt according to the principle of blocking a seat belt known from automotive engineering. This is a mechanism which, if a maximum rolling acceleration is exceeded and a centrifugal force acting on an element of this mechanism is exceeded, triggers and blocks the rolling process. Both ropes or belts, which are typically present, and the associated pulleys are preferably equipped with a corresponding fall brake.

In a second embodiment of the training device according to the invention, at least one of the pulleys, in this case designed as pulleys, are at least one of the pulleys at the end facing away from the bar to form a load acting as a tensile force on the person exercising guided ropes or belts arranged. According to a variant of this embodiment, this means for generating the tensile force, arranged at the end of at least one rope or belt, is a spring which is anchored to an abutment with its end facing away from the rope or belt. In this case, the tensile force caused by the spring can preferably be varied by changing a preload of the spring.

According to another variant of the second embodiment, the tensile force can be brought about by at least one weight element, preferably detachable and thus replaceable, at the end of at least one rope or belt. By exchanging the weight piece or pieces, a change in the tensile force acting on the barbell is also made possible in this variant. Preferably, it goes without saying that corresponding weight pieces are attached to both ropes or belts arranged on both sides of the barbell and typically have the same weight for a symmetrical load on the person exercising.

A further, third variant of the embodiment of the second embodiment consists in that the tensile force is produced by means comprising (electrical) at least one drive, which act on the end of at least one of the ropes or belts facing away from the dumbbell bar. In this case, too, the tensile force caused in each case can be varied by a corresponding control of the corresponding drive or drives.

According to a particularly advantageous embodiment of the invention, it is designed so that the training device can be converted to switch between the two embodiments described above. In this case, either the entire device carrier or at least its function carrier, which has the roles for the ropes or belts, can be exchanged for conversion to the respective other embodiment. In the course of a corresponding conversion it is achieved that either by a dumbbell bar with weights exerted a compressive force on a person exercising and when the dumbbell bar is lifted the ropes or belts are rolled up by the pulleys of the respective equipment wearer or that the dumbbell bar, by means of ropes or belts guided over pulleys acting as pulleys, with a pulling force Means (spring, weight element or element moved by a drive) is brought into an operative connection.

Due to its design with the device carrier movable along a cross member in a horizontal plane and the rotatability of the functional carrier of this device carrier with respect to its base carrier, the training device according to the invention enables very variable and flexible muscle training. A person using a dumbbell bar to impart a compressive or tensile force for their training can move relatively freely when performing the corresponding exercises, so they do not have to perform the exercises in a stationary position. Due to the rotatability between the basic carrier and the functional carrier of the device carrier, the person concerned can simultaneously rotate their upper body when lifting the barbell or when pulling on the barbell which is subjected to tensile force and can continuously move forwards and backwards and thus also other muscle groups at the same time stress and train your coordination.

Particularly for use in the rehabilitation sector, there is also the additional advantage that the exercising person is always safe without the need for assistance from another person. It is also very advantageous, in particular for use in the rehabilitation area, that the person exercising with the dumbbell can run at the same time when performing appropriate exercises. Depending on the type and degree of impairment of the person concerned, which necessitates the rehabilitation measures, it can also be advantageous if the exercising person is, as it were, gently forced to run at the same time when performing their exercises with the barbell. According to an embodiment of the invention provided in this respect, this can be achieved by the fact that the device carrier cannot only be guided passively in the horizontal direction along the traverse, but additional drives are provided which actively move the device carrier.

The crossbeam along which the equipment rack is moved can be a simple crossbeam, a double crossbeam or a multiple crossbeam, which is either designed as part of a portal structure or is mounted on the ceiling of a respective training room. This can be, for example, a rail system, preferably implemented by means of a double cross-member, in which the base carrier of the device carrier is movably guided due to a mounting by means of ball bearings or slide bearings in the manner of a roller slide.

According to another very advantageous development, the training device can be equipped with an electronic brake with regard to the rollers and the possibility of unrolling the ropes or belts, which only enables unrolling if it is recognized by means of sensors arranged on the barbell that a person exercising is using the barbell has grasped it with both hands or the bar is resting on a part of a person's body.

Finally, the training device can also be equipped with devices for generating a virtual reality to support the achievement of specific training goals.

• 2: die Ausbildungsform gemäß der 1 aus einem anderen Blickwinkel,
• 3: eine Portalvariante der in 1 gezeigten Ausbildungsform des Trainingsgeräts.

In the following, some aspects of the invention will be explained again with reference to drawings in the context of an exemplary embodiment. The drawings show in detail.

• 1 : a first variant of a possible embodiment of the training device according to the invention in an overall view,
• 2 : the form of training according to the 1 from a different point of view,
• 3 : a portal variant of the in 1 Shown form of training of the training device.

the 1 shows a possible embodiment of the training device according to the invention as an overall view in a spatial representation. This is a form of training in which the barbell 1 a compressive force is exerted on an exercising person. Next to the barbell 1 , on which weights on both sides to generate the compressive force 9 , 10 are arranged, make the traverse 2 running along the traverse 2 horizontally movable equipment carrier 3 , 4th that to the functionary 4th des from a basic carrier 3 and said functionary 4th existing equipment carrier 3 , 4th arranged pulleys 5 , 6th and over these pulleys 5 , 6th led, the barbell 1 holding ropes 7th , 8th essential elements of the training device.

In the training device shown as an example, the traverse is 2 designed as a double crossbeam to be attached to the ceiling of a room. One-piece with the crossbeam provided with holes 2 trained investment elements 12 ₁ - 12 _n the double crossbeam is brought to the system on a room ceiling and drilled into the Investment elements 12 ₁ - 12 _n anchored through it to the ceiling by means of screws or similar anchoring elements. With the traverse 2 , i.e. with the double traverse, is the basic carrier designed in the manner of a slide 3 of the device carrier 3 , 4th engaged. The functionary 4th with the pulleys arranged on it 5 , 6th is with the basic carrier 3 connected via a pivot bearing (not visible in the illustration). Due to the connection between the base carrier made via the pivot bearing 3 and functionaries 4th is the functionary 4th around the axis of rotation 13th around opposite the one with the traverse 2 engaged base carrier 3 and thus opposite the traverse 2 rotatable.

For the training, a person, for example a person who is in health rehabilitation training, grabs the barbell 1 with both hands or put it on your shoulders and press the barbell 1 against those by the weights 9 , 10 caused compressive force, under the barbell 1 - if necessary also in a stooped position - standing, upwards. This will be the barbell 1 with the device carrier 3 , 4th connecting ropes 7th , 8th on the pulleys 5 , 6th of the functionary 4th rolled up. Means on the barbell 1 arranged sensors, not shown here, it is preferably ensured that training with the dumbbell bar 1 is only possible if it is gripped by hand on both sides or rests flat on the shoulder and neck area of the person exercising. In any case, there is a downward movement of the barbell 1 beyond a basic or rest position prevents the presence of two hands gripping the dumbbell bar or a flat resting of the dumbbell bar by said sensors 1 is detected on one part of the body (shoulder-neck area). In this basic position, the barbell is 1 held in suspension without touching the sensors by means of a preferably electronic brake, the ropes 7th , 8th are pretensioned in such a way that, even without the aforementioned electronic brake acting, at least the unloaded brake, that is, not yet with weights 9 , 10 equipped barbell 1 keep in suspension.

Provided that an exercising person uses the barbell 1 has grasped both sides or has placed it on her shoulder and neck area, she can do this with the weight pieces arranged on it and dimensioned according to the desired training success 9 , 10 repeatedly against that of the barbell 1 with the weights 9 , 10 (actually only from the weights 9 , 10 - the weight of the barbell 1 itself is made by the pretensioning of the ropes 7th , 8th compensated) and lower it again, allowing lowering beyond a defined vertical basic or resting position.

The great advantage of the training device according to the invention is that the training person can move very freely within the room while performing the above-mentioned exercise. You can do the equipment carrier 3 , 4th and the barbell connected to it by the ropes 1 , including the weights 9 , 10 along the traverse 2 move and thus below the traverse 2 , with the barbell 1 in hand, run forwards and backwards. At the same time, she can also be the functionary 4th towards the base support 1 twist and thus, for example, twist your upper body sideways while performing the exercises and thereby specifically train specific muscle groups on the upper body and trunk as well as the legs in addition to the arm muscles. Depending on the needs and training objective, that is to say in particular depending on the requirements for rehabilitative training of a person, it can also be provided that the device wearer 3 , 4th or its basic carrier 3 by means of drives along the double traverse 2 moves and thus the exercising person is forced to a certain extent (certainly in a gentle way) while performing the exercises with the barbell 1 to run.

A very flexible use of the training device is given by the fact that the functionary 4th detachable with the base support 3 of the device carrier 3 , 4th is connected and thus against another functionary 4th can be exchanged. The function holder shown as an example 4th can thereby, for example, against a functionary 4th be exchanged, which makes it possible to use the barbell 1 a pulling force on the arms of a barbell 1 to exercise poignant person. With such a function carrier, not shown here 4th , would be the pulleys 5 , 6th designed as pulleys and attached to the barbell 1 remote ends of the ropes guided over the pulleys 7th , 8th appropriate means for generating the tensile force are arranged. As already stated earlier, the last-mentioned means can, for example, each be one with a rope 7th , 8th act connected and anchored at its other end to an abutment spring.

the 2 shows the form of training according to 1 again in a different view, namely viewed from a perspective from below the training device according to the invention. The system elements can be seen particularly well in this figure 12 ₁ - 12 _n for fastening the traverse 2 (Double traverse) on a room ceiling as well as details of the traverse 2 engaged equipment carrier 3 , 4th , like in particular the one at the functionary 4th of the device carrier 3 , 4th attached pulleys 5 , 6th . In the case of the 1 and 2 The embodiment of the training device shown is, as already stated, a form of training for imparting a pressure force to a training person via one with weight elements 9 , 10 provided barbell 1 . The one on the functionary 4th arranged roles 5 , 6th serve to make the ropes 7th , 8th over which the barbell 1 with the functionary 4th connected when lifting the barbell 1 on these pulleys 5 , 6th be rolled up.

In addition, the 2 an essential one, on the training device, more precisely on the device carrier 3 , 4th , the intended detail can be seen clearly. It is a part of the functionary 4th trained fall brake 11 . According to the principle of the belt brake known from vehicle technology, this prevents the weight-laden dumbbell bar from falling onto the person or the floor and possibly injuring the person in question in the event that it slips away from a person exercising. As soon as one of the designated elements of the fall brake 11 adjustable maximum unwinding speed on the rope pulleys 5 , 6th occurs, the fall brake is applied 11 triggered and prevents further unwinding of the ropes 7th , 8th from the pulleys 5 , 6th and with it every further downward movement of the barbell 1 with the weights 9 , 10 .

the 3 shows another variant of the 1 Shown embodiment of the training device according to the invention. This is a portal variant of the otherwise essentially the same form of training. This variant also uses the barbell 1 exerted a compressive force on an exercising person. The traverse 2 in this form of training forms the roof of the portal, so to speak. In addition, there are also here, in addition to the barbell 1 with weights 9 , 10 that from the basic carrier 3 and the functionary 4th existing equipment carriers 3 , 4th that to its functionaries 4th attached pulleys 5 , 6th as well as those about these pulleys 5 , 6th led, the barbell 1 load-bearing ropes 7th , 8th essential elements of this variant of the training device. This variant also has a fall brake, which cannot be seen in detail here 11 .

At this point it should be emphasized again that the 1 in a variant for ceiling mounting and in the 3 Form of the training device according to the invention shown as a portal variant essentially by merely changing the functional carrier 4th can be converted into a second basic form of training, in which by means of the barbell 1 a tractive force is imparted to a exercising person or their arms.
