Description

[0001]January 14, 2025 Back trainer The invention relates to a training device for training the human body, in particular the back. BACKGROUND OF THE INVENTION Various training devices for training the back muscles are known from the prior art. Such devices are also referred to as "back trainers." Back trainers, to which reference is made below, comprise a frame with a hip support and calf supports and enable a user to lean forward and, from this position, to move the upper body up and down. The user's hips rest on the hip support, and the legs are anchored to the calf supports. While such back trainers allow training of the back muscles, they do not offer any further training functions and, in particular, do not allow stretching the back or relieving strain on the spine.Training devices known from the prior art for training the back muscles are disclosed, for example, in DE 209912429 U1, DE 102015113113 A1, WO 2015 / 107458 A1, JP 3174189 U and DE 602004007396 T2. OBJECT OF THE INVENTION It is an object of the present invention to create a back trainer that allows the user, in addition to training the back muscles, to also stretch and relieve the back. This object is achieved according to the invention by the features specified in independent claims 1 and 12. Further embodiments of the invention emerge from the subclaims. The following describes two models of back trainers with a cantilever arm, which have the same basic structure but differ in the type of their cantilever arm.Model 1 According to the invention, a training device for training the human body and in particular the back muscles is proposed, comprising: • a frame with feet; • a hip support mounted on the frame and • calf supports mounted on the frame, wherein the hip support and the calf supports are arranged such that a user can bring themselves into a forward-leaning position with their stomach downwards, in which the hips rest on the hip support and the calves are hooked onto the calf supports, and the user can bend or stretch their upper body downwards from this position. The upper body of the user preferably projects freely forwards over the hip support and is not supported by the device. The training device according to the invention also has a boom arm which is pivotally mounted on the frame and preferably has at least one handle.The boom arm is designed such that it projects forwards lengthwise from the frame and is mounted on the frame so that it can pivot relative to the hip support. The user holds the boom arm while performing an exercise and it pivots along with them when they move their upper body up and down. The boom arm moves along a circular path. This introduces forces into the user's upper body which stretch the back. In a preferred embodiment of the invention, the boom arm has at least one, in particular at least two handles which the user holds on to while they swing the boom arm up and down. In another embodiment, the boom arm is rod-shaped and dimensioned so that it can be grasped with the hands. In this case, the user can pull themselves forwards along the boom arm with their hands and stretch their back at the same time. A scale, e.g.B. in the form of markings, which indicate the extent of the stretch. The pivot axis of the cantilever arm is preferably a horizontal axis that runs transversely of the back trainer. The cantilever arm is preferably mounted on the frame so that it can pivot freely. When the cantilever arm is operated, the user essentially only feels the force of gravity of the cantilever arm. The at least one handle is preferably arranged in the region of the head or longitudinally in front of the user's head. The cantilever arm preferably comprises a rod-shaped element to which the handle(s) are firmly mounted. In a preferred embodiment of the invention, a chest rest is arranged on the cantilever arm. The handle is preferably arranged further away from the pivot axis of the cantilever arm than the chest rest. The cantilever arm preferably extends below the upper body or next to the upper body of a user in the longitudinal direction of the back trainer.In a special embodiment, the cantilever arm can have arm pads for supporting the upper arms and / or forearms. According to a preferred embodiment of the invention, the cantilever arm is mounted on the frame in the area of ​​the hip support. The mounting point or pivot axis of the cantilever arm is preferably located at a height of 50 cm to 110 cm above the floor. In a further variant of the back trainer, the cantilever arm is designed to be height adjustable. The position of the hip support is preferably also adjustable. Two separate adjustment mechanisms can be provided for adjusting the height of the cantilever arm and the hip support. In a preferred embodiment of the invention, only a single adjustment mechanism is provided for both parts. The cantilever arm can, for example, be mounted on the adjustment mechanism of the hip support so that both elements can be height adjusted together.The length of the entire extension arm, including any parts mounted thereon, is preferably at least 50 cm and in particular between 70 cm and 150 cm. The extension arm is preferably designed to be length-adjustable. For this purpose, a conventional telescopic mechanism can be provided, for example. According to a preferred embodiment of the invention, the distance of the chest support and / or the distance of the handle is adjustable relative to the pivot axis of the extension arm. For this purpose, the back trainer can again comprise separate adjustment mechanisms or a common adjustment mechanism for both elements.Model 2 The present invention also relates to a training device for training the human body, in particular the back muscles, comprising: • a frame (2) with feet (3); • a hip support (4) mounted on the frame (2) and • calf supports (6) mounted on the frame (2), wherein the hip support (4) and the calf supports (6) are arranged such that a user can bring themselves into a forward-leaning position with their stomach facing downwards, in which the hips rest on the hip support (4) and the calves are hooked onto the calf supports (6), and the user can bend or stretch their upper body downwards from this position. The upper body of the user preferably projects freely forwards over the hip support and is not supported by the device. The user can therefore train against the full force of gravity of their upper body. The training device according to the invention also comprises a boom arm mounted on the frame, which projects forwards from the frame.In a preferred embodiment of the invention, the cantilever arm has a plurality of handles which are arranged at different distances from the frame. Some of the handles can be arranged further forward in the longitudinal direction and others further back. The handles are preferably located longitudinally in front of the user's head and preferably so far forward that the user can only reach them with essentially outstretched arms. In another embodiment, the cantilever arm is rod-shaped and dimensioned so that it can be grasped with the hands. In this case, the user can pull themselves forward with their hands along the cantilever arm and stretch their back in the process. A scale, e.g. in the form of markings, which indicates the degree of stretching can be attached to the cantilever arm. The cantilever arm can be rigidly connected to the frame. However, it can also be movable relative to the frame orbe mounted so as to be pivotable relative to the hip support. In the case of the pivoting version, the boom arm moves along a circular path. In the second model of the back trainer described here, the boom arm is preferably mounted on the frame in the area of ​​the feet, just above the floor. The mounting point or the pivot axis is preferably located at a height of 0 cm to 50 cm above the floor. According to a preferred embodiment of the invention, the handles are arranged in pairs on the boom arm, with a first pair of handles being arranged further forward in the longitudinal direction and a second pair of handles further back. A first pair of handles can also be arranged higher above the floor in the vertical direction than a second pair of handles.According to a preferred embodiment of the invention, the higher first pair of handles is preferably arranged further forward (further away from the user) and the lower second pair of handles is preferably arranged further back (closer to the user). Technical features of the two models can be combined at any time, provided this is technically feasible. This means that technical features described in connection with one of the models can be adopted in the other model at any time. The length of the extension arm can be telescopically adjusted in both models.

They show: Fig. 1 a perspective view of a back trainer with a extension arm according to a first model, wherein the extension arm is in a lower position; Fig. 2 a perspective view of the back trainer from Fig.1, with the boom arm in a middle position; Fig. 3 is a perspective view of the back trainer of Fig. 1, with the boom arm in an upper position; Fig. 4 is a perspective view of a back trainer with a boom arm according to a second model, with the boom arm in a lower position; Fig. 5 is a perspective view of the back trainer of Fig. 3, with the boom arm in a middle position; and Fig. 6 is a perspective view of the back trainer of Fig. 3, with the boom arm in an upper position. EMBODIMENTS OF THE INVENTION Fig. 1 shows a perspective view of a back trainer 1 according to a first embodiment of the invention, which allows a user to bring themselves into a forward-leaning position and to bend and stretch their upper body from this position.The back trainer 1 comprises, in a known manner, a frame 2 with feet 3, a hip support 4, and calf supports 6. Furthermore, the back trainer 1 comprises a cantilever arm 10 pivotably mounted on the frame 2. The cantilever arm 10 is designed such that it extends beneath the user's upper body in the longitudinal direction C of the back trainer 1 and is held by the user while pivoting in the direction of arrows A while performing back exercises. This applies forces to the user's upper body that stretch or extend the back. The cantilever arm 10 comprises a chest support 11 for supporting the upper body, as well as several handles 14 located approximately in the area of ​​the head or, in the longitudinal direction C, just in front of the user's head. The handles 14 are arranged further away in the longitudinal direction C than the chest support 11 with respect to a pivot axis 17 of the cantilever arm 10.The extension arm 10 further comprises several arm pads 13 for supporting the upper arms and arm pads 14 for supporting the forearms. A hinge 9 is provided on the frame 2, on which the extension arm 10 is pivotally mounted. The pivot axis 17 runs horizontally in the transverse direction of the back trainer 1. In the first model of a back trainer 1 shown in Figures 1-3, the extension arm 10 is mounted on the frame 2 in the area of ​​the hip support 11. The mounting point or pivot axis 17 of the extension arm 10 is located at a height of 50 cm to 110 cm above the floor. The extension arm 10 and hip support can be adjusted in height together, whereby only a single adjustment mechanism is provided for this purpose, which in the illustrated embodiment comprises a telescopic arm 8 and a locking screw 7. The boom arm 10 and the hip support 11 are attached to the telescopic arm 8 so that both elements can be adjusted together.The length L of the entire extension arm 10, including any parts mounted thereon, is preferably at least 50 cm and in particular between 70 cm and 150 cm. In this embodiment, the extension arm 10 is designed to be length-adjustable. For this purpose, a conventional telescopic mechanism is provided, by means of which the distance of the chest support 11 and, at the same time, the distance of the handles 14 from the mounting point or pivot axis 17 of the extension arm 10 can be adjusted simultaneously. In the view of Fig. 1, the extension arm 10 is in a lower position. Fig. 2 shows the back trainer 1 from Fig. 1 with the extension arm 10 in a middle position, and Fig. 3 shows the back trainer 1 from Fig. 1 with the extension arm 10 in an upper position. Fig. 4 shows a second model of a back trainer 1 in a perspective view.The basic function of the second model is identical to the first model and allows a user to lean forward and, from this position, to bend and stretch their upper body. The second model differs, however, in the design of its extension arm 10. The back trainer 1 shown in Fig. 4 comprises a frame 2 with feet 3, a hip support 4 and calf supports 6. In addition, an extension arm 10 with handles 14 is provided, which extends forward in the longitudinal direction C. The handles 14 are arranged at different distances from the frame 2. They are located so far forward that the user can only reach them with essentially outstretched arms. The extension arm 10 can be rigidly connected to the frame 2. In a second variant, the extension arm 10 can also be pivoted about a horizontal pivot axis 17.The extension arm 10 is mounted on the frame 2 in the area of ​​the feet 3, a few cm above the ground. The mounting point or the pivot axis 17 can, for example, be located at a height of 0 cm to 50 cm above the ground. As can be seen in Fig. 4, the handles 14 are arranged in pairs on the extension arm 10, with a first pair of handles 14 arranged further forward in the longitudinal direction and a second pair of handles 14 further back. The first pair of handles arranged further forward is also arranged higher above the ground in the vertical direction than the second pair of handles 14 arranged further back. In the view of Fig. 4, the extension arm 10 is in a lower position. Fig. 5 shows the back trainer 1 from Fig. 4 with the extension arm 10 in a middle position, and Fig. 6 shows the back trainer 1 from Fig. 4 with the extension arm 10 in an upper position.
