Description

Field of invention

The present invention relates to a training device for supporting physical training. Essentially, it concerns fitness and muscle building. More specifically, it relates to an attachment for an existing training device or a support element with which a training device with the desired function can be created.

Background of the invention

The US patent application 2017/0106230 A1 This reveals a training device that assists in the execution of squats. A movable element with shoulder support is guided along vertical bars. This allows for a controlled and precise movement of the shoulders and upper body. The movable part can be weighted.

A potential drawback is that this is a relatively complex and inevitably expensive piece of equipment that seems to only allow for one exercise. While such an option might be acceptable for gyms, it will generally not be attractive in situations where effort needs to be limited, such as when training at home.

The present invention aims to provide an attachment for a training device. In this way, effective training should be possible without the need to purchase an expensive and complex device.

This problem is solved by an attachment according to claim 1. Advantageous further developments are specified in the dependent claims. The corresponding advantages are found in the methods according to claims 10 to 12.

More detailed description

The present invention relates to an attachment for body training, which, together with a support part, can form a training device. The attachment is intended to be individually transportable and tradable. A potential user who purchases such an attachment is generally not primarily interested in the attachment itself, but rather in using a training device. However, it will often be the case that the user does not need to purchase a separate support part to use the attachment, but can use it with an existing support part.

A suitable support component typically offers a first and a second mounting element. The attachment can be connected to these mounting elements. This connection creates a training device.

The support element can take various forms. It may suffice to provide suitable mounting points at an appropriate height on a wall. Alternatively, mounting points could be provided on a wall bar, for example. Another viable option is to attach suitable mounting points to a door frame. Often, users will utilize a training rack or exercise frame as a support element. Such racks typically feature vertical posts, for example, four vertical posts arranged in a rectangle. These posts usually have numerous holes arranged vertically in rows, which can themselves serve as mounting points or provide a convenient attachment point for additional mounting elements.

The first and second mounting elements are advantageously positioned at a user's shoulder height. This is because the attachment typically includes an upper frame designed to provide support for the user's shoulder and is therefore expediently mounted at shoulder height. The term "shoulder height" serves here as a rough guideline and is not intended to be overly restrictive. Firstly, a user's shoulder height can vary considerably; secondly, even with a known shoulder height, mounting the attachment slightly above or below shoulder height may be advantageous. Therefore, in the context of the present invention, the term "shoulder height" will typically describe a height of 1.00 m to 2.20 m.

The attachment should generally include an upper frame (preferably circumferential). This upper frame should comprise a left shoulder lever and a right shoulder lever. Both shoulder levers are usually long pieces that exhibit high resistance to stretching, meaning they are essentially non-stretchable and, as a rule, advantageously also non-compressible and non-bendable. The terms stretchability, compressibility, and bendability in this context refer to typical forces encountered during use.

The left and right shoulder levers are complemented by a shoulder crossbar. This shoulder crossbar typically also serves as the primary connection between the left and right shoulder levers. The levers ensure that the upper frame runs around the shoulder levers via the shoulder crossbar. In this context, the left and right shoulder levers are also referred to as the first left lever and second left lever, respectively, and the shoulder crossbar is also referred to as the first crossbar.

The shoulder crossbar should generally provide a support surface for the user's shoulder. This support surface can be a section of the crossbar itself. Alternatively, the support surface may be anatomically shaped for optimal support, and may also include padding. The shoulder crossbar, or first crossbar, should therefore be able to guide a part of the user's body (typically the shoulder area or upper back) directly or indirectly during a training movement. Indirect guidance occurs when the shoulder crossbar is equipped with additional components, such as a support surface or padding, that establish contact with the body.

The shoulder levers should each have a support-side end and a body-side end. The support-side end is generally oriented towards the support element, and the body-side end is generally oriented towards the user's body, more specifically towards the user's shoulder area. The support-side end should be connected to the support element.

The training device is designed to enable a guided up-and-down movement of at least one part of the user's body, specifically a guided up-and-down movement of the shoulders. Naturally, this usually results in a supported up-and-down movement of the user's upper body. During the downward movement, the knees bend; during the upward movement, they straighten. The up-and-down movement is therefore generally similar to performing squats. However, it is a guided movement in which the user's shoulders cannot move freely. The left and right shoulder levers create a fixed distance between the user's shoulders and the support end of the levers, and thus between the support elements and the lifting mechanism.

The present invention aims to enable the adjustment of the distance between the support-side end of the first left lever and the support-side end of the first right lever. This adjustment often allows for optimal connection to various types of support elements. For example, it facilitates easy connection to posts at different or slightly varying distances. Such posts can be provided by a training rack. It is often advantageous to be able to adjust not only the distance between the support-side ends of the levers, but also the distance between the body-side ends of the levers and the overall distance between the levers.

To achieve this change in spacing, suitable mounting elements for the levers must be selected. In particular, suitable connecting elements for the levers to the first cross member must be chosen. The levers can be connected to the cross member directly or indirectly. A direct connection is often practical. One way to change the spacing is with connecting elements that can be moved along the cross member. Various mechanical connecting elements can be used for this purpose. If the cross member is essentially tubular, it is advantageous to use connecting elements where the ends of the levers grip the cross member. For example, the levers can have round sleeves or recesses and slide along the cross member over these. The round shape also allows movement of the levers around the longitudinal axis of the cross member.

Besides allowing for a better connection to a support element by varying the lever distance, this feature is also advantageous for better stowing the attachment when not in use. The attachment can thus be moved into a suitable ready position.

In another embodiment, the training device alternatively or additionally supports a guided up-and-down leg movement similar to a leg press. Positioning an upper frame at the approximate shoulder height described is also advantageous when used as a leg press.

The upper frame should be movable. Ideally, the shoulder crossbar should be movable along a circular path. For this to be possible, it is advantageous if the left and right shoulder levers are each movable along a circular path. It is particularly advantageous if the left and right shoulder levers are movable around a single horizontal axis. This will generally be a geometric axis, which need not be implemented as a physical component.

A training device that includes both an upper and a lower frame is particularly useful. Accordingly, an attachment that also incorporates a surrounding lower frame is advantageous. This frame is ideally comprised of a left hip lever, a right hip lever, and a hip crossbar. formed. In this diagram, the left hip lever and the right hip lever are also referred to as the second left lever and the second right lever, and the hip crossbar is also referred to as the second crossbar.

The hip crossbar advantageously features a support surface for the user's hip. This support surface can itself be a section of the hip crossbar; it is advantageously anatomically shaped and may also include padding. The hip crossbar connects the left hip lever to the right hip lever. Each hip lever has a support-side end and a body-side end. They are connected to the support element at their support-side end.

The support element typically also has a third and a fourth receiving element, with the third receiving element accommodating the left hip lever and the fourth receiving element accommodating the right hip lever. Advantageously, the left and right hip levers are also rotatable, with rotation about a (geometric) axis being particularly beneficial.

It is also beneficial if the shoulder crossbar and the hip crossbar are connected by a connecting element. This connection allows the shoulder and hip crossbars to move together at a predetermined distance. Consequently, the upper and lower surrounding frames also move together. This connection therefore provides even better guidance, as the user can then perform guided movements in both the shoulder and hip areas.

The connecting element is conveniently designed as a back support. This back support can provide support in the shoulder area, serving as a support surface for the shoulder, and it can also provide support in the hip area, serving as a support surface for the hip.

It is advantageous if the second levers or hip levers, like the first levers or shoulder levers, are movable relative to the second crossbar. It is particularly beneficial if the distance between the support-side end of the second left lever and the support-side end of the second right lever can also be adjusted. This also advantageously applies to the corresponding body-side ends or to the levers as a whole. However, it may suffice if, in the case of an attachment, the distance can only be adjusted for either the first levers or only the second levers. The ability to also adjust the distance of the second levers can, in turn, be advantageous for attaching the attachment to various types of support structures.

Furthermore, the relative displacement of the first left lever relative to the second left lever generally allows both left levers to be moved into a convenient ready position. This position is one in which the levers can be moved into a crossed position. The levers will then form a cross in a plane perpendicular to their direction of rotation—and thus usually also perpendicular to the path of at least the first or second crossbar. The exact geometric shape of the cross is not of great importance. What is important is that an overlap can be achieved in this plane. Similarly, the right levers (and any further pairs of levers) should also be able to be moved into a ready position. In this ready position, they each assume a crossed position. This generally requires a relative displacement of the levers.

It is also advantageous if locking devices are offered to hold the attachment in the ready position. For example, the two left levers could be connected to each other by a locking pin. The same applies, of course, to the right levers.

It is also advantageous if the attachment can be moved across the floor on casters when in its ready position. Since the attachment is intended to support heavy loads, it must be robust and therefore relatively heavy. It is conceivable that a caster be attached to the end of the first left lever and the first right lever (preferably at the support-side ends). In the ready position, the ends, particularly the support-side ends, can be oriented towards the floor so that the casters allow the attachment to be supported. It is advisable to supplement two such casters with a third.

This third roller can be provided on a connecting element between the crossbeams. For example, it can be located on or in extension of the back support. It can also be provided on an attachment to the connecting element. In particular, it is advantageous if a support is provided on the connecting element and this roller is mounted on this support. The support can then assume a supporting position, and in this position, it braces the attachment against the ground during use. The support can then also assume a transport position and, in this transport position, use the roller to also support the attachment against the ground.

It has been shown that it is advantageous for the attachment to assume a position in its ready position where the connecting part (often a back support) is relatively upright. This allows for safer and more comfortable movement of the attachment. It is beneficial if the support surface of the connecting part/back support forms a small angle with the vertical, that is, an angle of less than 30° or even less than 20°.

It is also advantageous if the connecting piece allows the distance between the shoulder crossbar and the hip crossbar to be varied. It is possible to adjust the distance between the shoulder and hip crossbars so that it corresponds to the distance between the mounting elements for the upper and lower frames. If the shoulder levers move around a first horizontal axis and the hip levers around a lower horizontal axis, the distance between the shoulder and hip crossbars can be exactly the same as the distance between these horizontal axes. However, a different distance may be preferable.

During movement, in a side view, a shoulder lever, a hip lever positioned below it, the connecting piece, and an imaginary line between the upper horizontal axis of rotation and the lower horizontal axis of rotation form a parallelogram. This parallelogram shape is maintained throughout the movement.

It can also be advantageous to create a larger or smaller distance between the shoulder and hip crossbars using the connecting element. A slightly smaller distance has proven particularly useful. This results in a shoulder lever and a corresponding hip lever converging towards the body of the trainee. The imaginary extensions of these levers then intersect at a point far behind the trainee. This leads to a movement that is not quite circular, which has proven beneficial.

It is advantageous if the attachment is equipped with at least one weight holder (this can be located, for example, on the upper or lower frame). Adding weight using the weight holder intensifies the workout. In particular, the upward movement must then be performed against a downward pull. It is especially practical to provide one or two weight holders, ideally in the form of one or two prongs. These prongs can accommodate weight plates (with a central hole). Since many users already have such weight plates readily available, the attachment makes it easy to intensify training without having to purchase expensive additional equipment.

Weight can also be applied to the attachment using cables. These cables can be routed to the attachment in various suitable ways. They can exert either an upward or downward pull. The tensile force on a cable or cable is typically generated by a weight block.

It is also advantageous if the attachment can be supported by a stand on the ground. Especially when the attachment is weighted, it doesn't need to be held close to the ground by the user or supported in a low position, but can be supported at a convenient height above ground level. Such a stand can have two legs. Ideally, the legs can be rotated to bring them into contact with the ground. The stand typically has a position where it is not in contact with the ground, for example, by positioning its legs in a virtually horizontal position. For this, it is helpful if the stand can be rotated.

It is also advantageous if the attachment can be supplemented by a pressure plate oriented towards the ground. Such a plate can be designed to be removable. The attachment can then be used with or without such a plate. Various mechanical connections can make this possible.

This floor-oriented pressure plate can be used for leg training exercises, in which a user lies on the floor and supports their legs from below against the pressure plate.

The pressure plate can therefore be designed in various shapes; a flat plate is possible, as is an anatomically shaped design. The crucial point is that a user can exert upward pressure with their feet.

The exact orientation of the press plate is not crucial. In principle, an orientation of the press plate that is essentially parallel to the upper frame 12 or to the lower frame 22. A slight inclination relative to the plane defined by the lower frame 22 is also possible; a slope of plus to minus 30° is expediently chosen.

Overall, the invention relates to an attachment 10 for body training, which, together with a support part 20, can form a training device that offers at least one articulated quadrilateral for guided body movement. This quadrilateral consists of a section of the support part, an upper arm (e.g., the right or left shoulder lever), a lower arm (e.g., the right or left hip lever), and a connecting element between the upper and lower arms (e.g., a back support). The body movement is intended to take place against a selectable force.

• - das Anbauteil 10 mindestens einen ersten linken Hebel 14 und einen zweiten linken Hebel 24 umfasst, wobei der erste linke Hebel 14 um eine erste Achse und der zweite linke Hebel 24 um eine im Wesentlichen parallele zweite Achse drehbar sind

The present invention also relates to a device for connecting an attachment part to a support part 20, wherein

• - the attachment 10 comprises at least a first left lever 14 and a second left lever 24, wherein the first left lever 14 is rotatable about a first axis and the second left lever 24 is rotatable about a substantially parallel second axis

• - the first left lever 14 and the second left lever 24 can be moved from a crossed to a non-crossed position by rotation around the first and/or the second axis
• - the attachment part 10 is connected to the support part 20

Of particular interest is a method in which the attachment includes rollers and is moved to the training rack on these rollers before being connected to the training rack.

Furthermore, a method is appropriate in which the attachment has a back support and this assumes an angle of inclination to the vertical of no more than 30° when the attachment is moved on rollers.

1 Figure 1 shows an attachment 10 according to the present invention. The attachment 10 comprises an upper frame 12. This upper frame 12 consists of a left shoulder lever 14 and a right shoulder lever 16. The two shoulder levers (one could also speak of levers or arms) are connected by a shoulder crossbar 18.

The attachment 10 is mounted on a support part 20. For clarity, the support part 20 is only partially shown.

The attachment 10 further comprises a lower frame 22, which consists of the left hip lever 24, the right hip lever 26 and the connecting hip crossbar 28.

The upper frame 12 and the lower frame 22 are connected to each other by the back support 30. More precisely, the back support 30 connects the shoulder crossbar 18 and the hip crossbar 28. The upper frame 12 and the lower frame 22 are therefore only movable simultaneously.

The back support is supplemented by a left shoulder strap 32 and a right shoulder strap 32. Bridge 34. In this way, the shoulders are also well guided. In particular, it is easy to use the shoulders to move the shoulder straps and thus the attachment 10 upwards.

At the level of the shoulder crossbar, a left prong 36 and a right prong 38 are provided. These are positioned as an extension of the shoulder crossbar 18 and can conveniently also form a common component with the shoulder crossbar 18. The prongs are suitable for holding weight plates with a central hole. The weight plates are usually secured by clips attached to each prong. Other weight mounting methods would also be suitable. The prongs allow the use of standard round weight plates and easy adjustment of the weight load. Adding weight to the attachment enables effective training, particularly of the leg muscles. The basic movement is similar to performing squats, but because the body is guided by the back support 30 and the shoulder supports 32 and 34, the training is safer and more effective.

The downward movement of the attachment can be limited by the stand 40. The attachment 10 can rest on the floor using the stand 40. This allows a trainee to more easily assume the correct training position, as the stand 40 ensures that the shoulder straps 32 and 34 are at approximately the correct height. The stand 40 has a left leg 42 and a right leg 44. It also has an operating lever 46. The bracket 48 of the stand 40 is designed as a sleeve that encloses the hip crossbar 28. In this way, the stand 40 can be rotated about the axis of the hip crossbar 28. This allows for the simple construction of a robust stand 40. By pulling the operating lever 46, the legs 42 and 44 can be moved into a position away from the floor. It is practical and aesthetically advantageous if the legs 42 and 44 run essentially parallel to the hip levers 24 and 26.

The attachment is advantageously combined with a footrest 50. The footrest has a support surface 52 for placing the feet. This support surface 52 is held by a frame 54. The angle of the support surface 52 can be adjusted relative to the frame 54.

The support element 20 includes, in particular, the left support post 56 and the right support post 58. The attachment part 10 can be connected to these support posts. The support posts have receiving elements for this purpose. The left shoulder lever 14 is attached to the first receiving element 60, and the right shoulder lever 16 is attached to the second receiving element 62. The receiving elements are at the same height, so that both shoulder levers can rotate about a horizontal axis. Similarly, the third receiving element 64 is provided for the left hip lever 24, and the fourth receiving element 66 for the right hip lever 26. The support element 20 also includes further support elements 68, in particular cross braces, which are only partially shown here for the sake of simplicity. The support posts rest on feet 70.

2 Figure 1 shows a perspective view of the attachment together with a support element 20. The support element 20 corresponds to the one in Figure 20. 1 However, in this view four support posts can be seen, arranged in a square and connected by cross braces.

The support element comprises, in particular, the vertical posts 56 and 58 already shown. These two support posts facing the attachment are complemented by corresponding rear support posts, namely support posts 56A and 58A. The posts are connected by cross braces. Cross brace 68A is provided at the top, and cross brace 68B is located opposite it. Support posts 56A and 58A are connected by cross brace 68C. Support posts 56 and 58 are connected by cross brace 68D. Cross braces are also provided in the lower section of the support posts, namely cross braces 68E, 68F, and 68G. In this way, a support element can be provided that can also serve as a training frame for various other fitness exercises.

In this case, the attachment is mounted only to the front support posts, namely the left support post 56 and the right support post 58. For this purpose, the upper frame 12 is attached to the first mounting element 60 and the opposite second mounting element 62. The lower frame 22 is held by the third mounting element 64 and the fourth mounting element 66. The upper and lower frames are connected by the back section 30. A footrest, which provides a support surface 52, can be placed loosely on the ground or connected to the support section 20.

3 Figure 1 shows a top view of the attachment 10, which is mounted on a support part 20. For clarity, only the essential elements are labelled. The left shoulder lever 14 and the right shoulder lever 16 are clearly visible; together with the shoulder crossbar 18, they form the upper frame 22. The left hip lever 24 and the right hip lever 26 are also clearly visible. The lever 26, connected by the hip crossbar 28, forms the lower frame 32. In this illustration, it is clearly visible that the left pin 36 and the right pin 38 represent an extension of the axis of the shoulder crossbar 18. This allows the pins to be mechanically connected to the upper frame with particular strength, for example, by using a common component, such as a tube, to manufacture the shoulder crossbar 18 and the left pin 36 and the right pin 38.

It is also clearly visible that the left leg 42 and the right leg 44 are each supported on the floor near the hip levers. A wide support surface 52 is provided on the footrest for the trainee's feet. The back support 30 is positioned centrally between the shoulder levers and the hip levers.

4 shows a cutaway side view of the attachment part 10 according to the invention. 3 and a corresponding support element 20. The support element 20 provides, in particular, the right support post 58. The right shoulder lever 16 is mounted on the second receiving element 62 of this support post, and the right hip lever 26 is mounted on the fourth receiving element 66. The levers are rotatable about axes of rotation that pass through the receiving elements. This is generally desired within the scope of the present invention, although, depending on the design of the receiving element, the axes of rotation may only be located near the receiving elements.

The shoulder lever 16 is connected to and supports the shoulder crossbar 18. The hip lever 26 is connected to and supports the hip crossbar 28. Both crossbars are connected by the back support, which also supports the shoulder strap 34. The hip crossbar 28 is connected to the stand 40, the right leg 44 of which is visible. The footrest 50 is also positioned in the area of the support post 58. The use of a footrest is not required, but is generally advantageous. In general, the footrest can be connected to the support part or used without being connected to the support part, as described in the present invention.

The right shoulder lever 16 runs along axis A1 _, which passes through the lever's pivot point, i.e., through the second mounting element 62. The hip lever 26 runs along axis _A2 , which passes through its pivot point, i.e., through the fourth mounting element 66. In the illustrated configuration of the attachment 10, both axes move parallel to each other about the aforementioned pivot points. This results in a movement of the back support 30 towards and away from the floor, during which it remains at a constant angle, measured, for example, to a vertical line. Essentially, a parallelogram movement takes place, with the parallelogram being formed by a section of the post 58, the shoulder lever 16, a substantial part of the back support 30, and the hip lever 26.

Within the scope of the present invention, it is generally possible to vary the height of the receiving elements on the support part. For example, the receiving elements can comprise holes in the support part or even a row of holes. The shoulder levers and hip levers can then be received at the height of each hole. Accordingly, it would also be possible to mount the right hip lever 26 higher on the support post 58. In that case, the axis _A2 would not run parallel to the axis _A1 , but the axes would converge (and would meet in an area to the left of the support post 58, outside the area shown in the drawing).

This arrangement results in an alternative movement. In this alternative movement of the attachment 10, the lower part of the back support 30 would move downwards towards the support post 58. This would combine the up-and-down movement with a slight translational movement (especially of the trainee's pelvis) towards the support post 58. This training has proven to be particularly efficient.

Therefore, attaching the shoulder levers and/or the hip levers to pivot points at different heights is highly desirable within the scope of the present invention. Generally, within the scope of the present invention, a four-part articulation can be sensibly formed using one shoulder lever and corresponding hip lever, a section of the support element, and a connection between the body-side ends of the levers.

5 Figure 1 shows an enlarged view of the stand 40. The stand 40 comprises, in particular, a left leg 42 and a right leg 44. These legs can support the lower frame and thus the entire attachment from below. The legs 42 and 44 generally rest on the same ground level as the support element 20, which may also be supported by its feet 70. The two legs 42 and 44 are connected to each other by the bracket 48. This bracket is designed as a sleeve through which the hip crossbar 28 runs. In this way, the legs can effectively support the hip crossbar 28. Furthermore, this makes it easy to provide a rotatable stand 40. The axis along which the hip crossbar 28 runs serves as the axis of rotation around which the legs 42 and 44 can rotate. The extension of the stand 40 can be guided by the operating lever 46. Advantageously, locking mechanisms are provided in the lower position (support position) and in an upper position. An ideal upper position is achieved when the legs 42 and 44 run essentially parallel to the hip levers 24 and 26.

The stand 40 also supports the upper frame 12 via the connection between hip crossbar 28 and shoulder crossbar 18, which is achieved by the back support 30, so that, for example, the shoulder straps 32 and 34 can be held at a height convenient for getting in.

6 Figure 1 shows an enlarged representation of a generally advantageous connection between the levers of the attachment and the support part, as defined by the invention. The connection of the left shoulder lever 14 to the left support post 56 is shown. The support post 56 has a row of holes on the side where contact with the shoulder lever 14 is to be made, including, for example, hole 72. The shoulder lever 14 also has a plurality of holes, including, for example, hole 74. By connecting two matching holes, the shoulder lever can be connected to the support post. A threaded bolt 76, secured with the wing nut 78, can be used for this purpose. By providing a plurality of alternatively usable holes, the position of the shoulder levers, as well as the hip levers, can be easily adjusted, particularly with regard to the height of the pivot points. Since training frames, which already have posts with rows of holes, are suitable as support elements, a variable connection in this manner is possible without much effort.

7 Figure 1 shows a side view, looking at the left side of the attachment, of another attachment 10 according to the invention. This attachment is in turn mounted on the support part 20, which essentially has the shape of a conventional training rack. In particular, it provides the left support post 56. The left shoulder lever 14 is attached to this support post by means of the receiving element 60. Similarly, the left hip lever 24 is attached to the support post 56 by means of the receiving element 64. The back support 30 is provided at the user-side end of both levers. This is located between the crossbars, i.e., the shoulder crossbar and the hip crossbar, which are not clearly visible in this view. The left shoulder strap 32 is also provided adjacent to the back support.

In contrast to the other embodiment shown, a central weight receptacle 82 is provided here. This comprises an upwardly directed pin which is held by a crossbar that runs essentially perpendicular to the back support. A central weight receptacle is often just as effective as two lateral weight receptacles.

In this embodiment, only one central stand/support 80 is provided. This is located essentially centrally between the hip levers.

8 shows in a perspective view the alternative embodiment of an attachment according to the invention, as already shown in 7 was depicted. 7 However, the attachment 10 was shown in its functional position. 8 The attachment is now shown in a ready position, meaning it is not connected to any support and therefore cannot be used directly for training purposes. On the left side, the attachment comprises the left shoulder lever 14 (also called the first left lever) and the left hip lever 24 (also called the second left lever). On the right side, it includes the right shoulder lever 16 (also called the first right lever) and the right hip lever 26 (also called the second right lever). The shoulder crossbar 18 (or first crossbar) and the hip crossbar 28 (or second crossbar) are also visible. The left shoulder lever 14, together with the shoulder crossbar 18 and the right shoulder lever 16, can form the upper frame 12. The left hip lever 24, together with the hip crossbar 28 and the right hip lever 26, can form the lower frame 22.

In the operating position of the attachment 10, the corresponding shoulder and hip levers can assume an essentially parallel position. As in 7 As shown, the left hip lever 14 can essentially run parallel to the left hip lever 24. The same applies to the right levers. It can be useful and even very advantageous to choose a less than perfectly parallel position for the levers, for example by varying the distance between the receiving element 60 and the receiving element 64. However, the levers do not cross in the operating position.

The situation is different in the depicted ready position. In this ready position, the left shoulder lever assumes a crossed position relative to the left hip lever 24. Similarly, the right shoulder lever 16 assumes a crossed position relative to the right hip lever 26. This crossed position is already clearly visible in the perspective view; it becomes particularly apparent when the levers are viewed from the direction of their axes of rotation, that is, here from the direction of, for example, the longitudinal axis of the shoulder crossbar 18. The levers describe Essentially an X-shape. The exact shape is not crucial, but it is practical and advantageous if the levers cross.

The levers can best – and often only – assume this crossed position when they are movable relative to each other in the direction of their axes of rotation. In the illustrated embodiment, the direction of the axis of rotation coincides with the longitudinal axis of the shoulder crossbar 18 (and also with the longitudinal axis of the hip crossbar 28).

Connecting elements are visible at the support-side ends of the levers. These connecting elements are used to join the ends of the levers to a section of the support part. Here, the connecting elements are designed as sleeves that can accommodate a pin, which in turn creates a connection with the support element, for example, a mounting hole in a support post.

The connecting element 84A is provided at the end of the right hip lever 26, the connecting element 84B is provided at the end of the right shoulder lever 16, the connecting element 84C is provided at the end of the left shoulder lever 14 and the connecting element 84D is provided at the end of the left hip lever 24.

Connections to the struts are provided at the opposite ends of the levers. The connecting element 86 of the left hip lever 24 with the hip cross strut 28 is clearly visible – and therefore highlighted as an example. This element is designed so that the left hip lever 24 can rotate freely around the hip cross strut 28, whose longitudinal axis also forms the axis of rotation of the right hip lever 26.

The connection of the right shoulder lever 16 to the shoulder crossbar 18 is effected by the connecting element 88. This element also allows the right shoulder lever 16 to rotate about an axis of rotation that coincides with the longitudinal axis of the shoulder crossbar 18. The connecting element 88 additionally allows the right shoulder lever 16 to be displaced along this longitudinal axis of the shoulder crossbar 18. The shoulder crossbar 18 is designed as a round tube. Accordingly, the connecting element 88 can comprise a round sleeve that surrounds the tube. This sleeve allows both rotation about the longitudinal axis of the tube and displacement along this longitudinal axis. In this way, a connecting element that allows both rotation and displacement simultaneously can easily be manufactured. Therefore, providing a sleeve or round recess as a connecting element for a lever is generally of interest within the scope of the present invention.

Within the scope of this invention, it is generally conceivable that only the shoulder levers or first levers, or only the hip levers or second levers, are displaceable along the corresponding crossbars. It is also conceivable that both levers are displaceable. Relative displacement is advantageous; therefore, it suffices if only the shoulder levers or the hip levers are displaceable. As a result of this relative displacement, it is possible for one hip lever and one shoulder lever to assume a crossed position. This crossed position allows the attachment 10 to be moved into a compact ready position.

To fix the attachment 10 in this ready position, locking pins 92 can be used. The locking pin 92A is guided through corresponding openings in the left shoulder lever 14 and the left hip lever 24. Similarly, the locking pin 92B is guided through corresponding receptacles in the right shoulder lever 16 and the right hip lever 26.

In this compact and preferably secured ready position, the attachment is easily transportable. It is even easier to transport if casters are appropriately provided. In the illustrated embodiment, casters are provided at the support-side ends of the shoulder levers. This is advantageous because the shoulder levers are somewhat longer than the hip levers. In principle and generally, however, casters can also be provided at the hip levers within the scope of the present invention. Caster 94A is provided at the support-side end of the left shoulder lever 14. Caster 94B is provided at the support-side end of the right shoulder lever 16.

In this embodiment of the invention, a third roller is added to these two rollers. To achieve a very convenient ready position, the central support 80 can be folded down relative to the back support 30. Using the locking mechanism 96, the support 80 can be moved into a position extending the back support. In this position, the support 80 is ideal for bracing the attachment 10 against the ground. This position is in 7 The locking mechanism 96 also allows the central support 80 to be moved into a position where it is approximately perpendicular to the back support 30. The exact angle to the back support 30 is not relevant, but it is useful that the central support 80 can be positioned in a flat orientation. The release mechanism extends away from the back support. The locking mechanism 96 allows the back support 80 to be fixed in this position as well. In this way, the back support 80 can be used effectively to attach the roller 98. The roller 98 then forms an approximately equilateral triangle together with the rollers 94A and 94B.

Since the attachment is designed to allow training with heavy weights, such as 100 kg or more, it must be robustly constructed and is therefore generally not easily portable. However, the inclusion of wheels allows the attachment to be moved easily. This way, a training rack can be used sometimes with and sometimes without the attachment.

It can be seen that in the ready position of the attachment, the backrest is relatively upright. Here, the backrest forms an angle of less than 30° with the vertical.

Overall, it can be seen how a sophisticated training device can be created using very simple means and by utilizing an existing support component.
