Description

[0001] Training device with pull sled

[0002] Field of the invention

[0003] The present invention relates to an attachment for fitness training. The attachment is typically used together with a frame or post to form a training device for upper body training.

[0004] Background of the invention

[0005] A wide variety of training equipment is available. Some are optimized for use in sports facilities, such as commercial gyms. Other training equipment, which is usually lighter and less expensive but also offers fewer features, is designed for home use.

[0006] US Patent 6,669,607 B2 offers a training device for performing dumbbell training. The dumbbell is not moved freely, but rather is guided by two pull ropes. The pull ropes, in turn, are guided by arms. These arms are movable around vertical axes. Thus, the distance between the arm ends can be adjusted horizontally. The disclosed training device enables modified dumbbell training. However, it does not allow for a great deal of variability in the selection of exercises.

[0007] US patent application 2014 / 0121071 A discloses a training device with a pulley. The exerciser works against movable weights. The pulley is guided over a pulley, which in turn is guided on a curved vertical bar. The training device allows a precisely designed strength exercise to be performed with the pulley. However, it also appears to be optimized for only one type of muscle exercise. While it seems feasible for a gym to set up a variety of such specially optimized training devices, this generally does not seem possible or attractive for home use.

[0008] US Patent 11,369,833 B2 discloses another apparatus in which training is performed by pulling on a rope. The counterweight is provided by round weight plates. Such face plates are also frequently used for dumbbells and are therefore generally available both in gyms and at home. The pull rope, which is used to work against the weights, is guided over a pulley whose height is adjustable. This provides increased, but still not great, variability in training. In particular, it is not intended to train both sides of the body simultaneously, or at least not to do so with two pull ropes. Furthermore, a separate frame is required, which is only useful for this device.

[0009] The present invention aims to provide an improved attachment for a training device and overcome recognized disadvantages of the prior art. This attachment should be suitable for a variety of exercises, while at the same time being available in an inexpensive and space-saving manner. This makes it particularly suitable for home users.

[0010] This object is achieved by an attachment for a fitness device according to claim 1. The corresponding advantages are also provided by a method according to claims 13 to 15.

[0011] Further description

[0012] The present invention relates primarily to an attachment for a fitness device. Such an attachment should be individually producible, individually sold, and individually transportable. The attachment alone does not constitute a fitness device. However, the attachment can be mounted, for example, on a post. Mounted on the post, the attachment forms a training device for fitness training. The attachment should be easily connected to a support element, such as a post. It should also be easily detachable. Preferably, both can be achieved without tools. It may be advantageous to offer the attachment together with a frame, even mounted on such a frame.

[0013] The precise nature of the post or vertical support is irrelevant for the present invention. The terms "support" or "post" refer here to a suitable support element. Such a support element should be suitable for firmly mounting the attachment. As a rule, mounting at approximately chest or shoulder height is appropriate.

[0014] A post is particularly suitable as a vertical support for the attachment. Such posts are often already part of training equipment, marketed as a training rack, fitness rack, or power rack, for example. The attachment can then be mounted to an existing piece of training equipment. For example, weight training racks are often offered with four posts arranged in a rectangle and connected in a suitable manner. Such a post can then be used to mount the attachment.

[0015] It is often practical to assemble two attachments. This results in a piece of fitness equipment in which one attachment can be used for one half of the body and the other for the other half. It is also conceivable to construct a piece of fitness equipment using three, four or more attachments. As a rule, however, two attachments are used, or at least two attachments per user of a piece of fitness equipment. If, perhaps in a gym, a large rack with numerous posts is available, it is quite conceivable to provide a pair of attachments for each user. The attachment should comprise an elongated piece. Such a elongated piece achieves an extension in one direction that is considerably greater (for example, at least ten times greater) than the extension in other directions. The elongated piece can be in the shape of a tube.The direction of the main extension also determines the direction of a longitudinal axis. The longitudinal axis is usually an axis of symmetry. For example, if the long piece is offered in the form of a round tube, the longitudinal axis lies at the center of the circular cross-section.

[0016] The fixture should be designed for mounting on a vertical support. For this purpose, the fixture may include fasteners suitable for connection to such a support. The support should run at least predominantly vertically, i.e., its direction of extension should have a vertical component that is larger than the other components. The fastener should be designed such that the longitudinal axis of the long piece does not run vertically (at least not exclusively or always) or, generally speaking, can take a direction that deviates from the main extension direction of the support.

[0017] A suitable connecting means for connecting the long section to the support is a bracket. This bracket can at least partially enclose the support. The bracket can also be connected to the support by mechanical means, for example, by screwing. A particularly suitable bracket is a sleeve that surrounds the vertical support. The connecting means can comprise a joint.

[0018] The joint can expediently have an axle or a bolt that defines an axis of rotation. The arm can have receptacles for such a bolt, for example two holes with recesses for passage. Overall, it is therefore expedient if the connecting element has a sleeve part for connecting to the support and a joint part for the movable connection of the long piece. It is also important that the long piece can permanently assume various positions in space. The long piece should therefore not only be able to be adjusted, for example, between a vertical and a horizontal position, but also only be able to be fixed in the vertical or horizontal position, but it should also be able to be held in several positions - for example, more than two, three or four. Locking mechanisms are helpful for this purpose; for example, a row of holes with a large number of locking positions can be useful.Bolts can secure the long section in various locking positions. This allows the long section or arm to permanently assume various spatial orientations. This can be a continuum of different positions or a multitude of spaced positions, preferably three, four, five, ten, or more. The long section should be fixable in these positions so that training can take place.

[0019] The long section should include a movable carriage. This carriage should be movable, at least essentially, along the longitudinal axis of the long section. Typically, the carriage is movable in two directions: forward and backward.

[0020] Fitness training is intended to take place by moving the movable sled against a tensile force. Such a tensile force can make movement in only one direction difficult; for example, the sled can be pushed away from the body against a tensile force. Alternatively, the sled can be pulled towards the body against the tensile force. It is also conceivable that the tensile force is effective in both directions during movement. A sled should offer more than one adjustment option for a handle or the like. Therefore, the sled should be easy to move. Easy mobility can be achieved expediently with a sliding or lubricant or with mechanical bearings, for example a ball bearing or a roller bearing.

[0021] To ensure easy movement of the slide, it may be useful to equip the arm with an additional guide rail. Such a rail can be attached, for example, by screwing or, in individual cases, by welding or gluing. Although the slide can also be guided directly on the arm, guiding it on a special rail often involves less resistance. The arm can then be used to provide additional mechanical stability or, for example, to provide a series of locking holes to fix the slide in specific positions if necessary.

[0022] Such a rail can have various shapes. A geometric shape that can be positively connected to the slider in such a way that the slider cannot detach from the rail is preferred. Ideally, the cross-section of the rail and the cross-section of the slider are matched so that only displacement along the longitudinal direction or main extension of the rail is possible.

[0023] A rail which tapers towards the arm in such a way that it is wider in at least one plane parallel to the contact surface with the arm than in the plane of the contact surface is advantageous.

[0024] A rail with two opposing guide grooves is also advantageous. Undercuts are advantageously provided on the rail, preferably in the guide grooves. A slider that encompasses the rail over an angular range of more than 180°, preferably more than 270°, is also advantageous. This allows for a slider that can be moved along the rail but cannot be removed from it.

[0025] A splint that is connected to the arm at more than two points, and preferably over more than 50% to more than 80% of its length, is also advantageous. It can also be connected to the arm over its entire length.

[0026] Such a rail can be easily combined with an arm with a rectangular or square cross-section. It can be mounted on one side of the arm. It advantageously has a flat mounting surface. It is therefore often provided as a separate component and can then be removed from the arm.

[0027] It is advantageous if the tensile force is transmitted by a traction cable. The tensile force can be generated at the other end of the traction cable, for example, by weights. Such weights can be guided vertically, and the downward force can be transmitted in a different direction by the traction cable. In particular, the traction cable can run essentially parallel to the longitudinal axis of the long section and be effective. Tensile force can also be generated in other ways, for example, by spring force or by an electromechanical resistor, or even a combination of these possibilities.

[0028] The long section has an end closest to the support and an end far from the support. This assignment arises when the long section is mounted on a support. It also arises if the long section has means for connecting to the support. It is expedient if a traction cable is guided from the end of the long section closest to the support to the end far from the support. If the long section is a tube, i.e., has an internal hollow space, it may be expedient to guide the traction cable within this hollow space. The traction cable is expediently guided further from the end far from the support to the carriage. A deflection pulley can be used for this purpose. Such a deflection pulley is therefore expediently provided at the end far from the support.

[0029] Alternatively or additionally, a deflection pulley can also be provided at the end closest to the support. In particular, such a deflection pulley can serve to exert a tensile force that pulls the carriage toward the end closest to the support.

[0030] It is useful to provide a detachable connection between the pull rope and the sled. Such a connection could be implemented, for example, using a hook, perhaps a snap hook, and an eyelet. The pull rope could also be used for fitness exercises that do not involve a sled. For example, the pull rope could be connected to a handle using a snap hook. The pulling force provided by the pull rope can then be used for a variety of fitness exercises.

[0031] The carriage can be designed in a variety of ways. It should preferably be easily movable along the long piece. Mobility is expediently restricted to movement along the longitudinal axis. In this direction, the carriage preferably has low resistance to movement. For this purpose, it is advantageous if the carriage has one, two or more - generally a plurality of - rollers with which it moves over the long piece. It can be advantageous to provide two rollers for each surface of the long piece. For example, two rollers can slide along the top side of the long piece. It can also be expedient to provide opposing pairs of rollers. For example, one roller can be in contact with the top side of the long piece and an opposite roller can be in contact with the bottom side of the long piece. In this way, it is possible to use a carriage with four, six, or eight rollers.It may also be useful to design the rollers in such a way that they are hollow and replicate the contour of the long piece.

[0032] A carriage can be conveniently designed by having an upper guide plate and an opposite lower guide plate. The guide plates can be connected by bolts. It is useful if these bolts also provide axles for rollers that guide the carriage along the sides of the long section.

[0033] It's also useful if the sled has a handle. This allows the sled to be gripped for fitness exercises and pulled toward and / or pushed away from the body. Handles with adjustable handle orientation are particularly suitable.

[0034] It can also be useful if the sled has a weight holder. This can be offered in the form of a mandrel onto which weights, such as weight plates with a central hole, can be attached.

[0035] It is advantageous if the connecting element or sleeve for connecting the long section to a support is movable relative to the long section. It is useful if the connecting piece is movable relative to the longitudinal axis about at least one axis of rotation. It is even more advantageous if it can be moved about two mutually perpendicular axes of rotation.

[0036] With such an attachment, it is possible for the longitudinal axis to assume different spatial directions relative to a vertical post. For example, the first rotation axis can be oriented horizontally, allowing the long section to be oriented so that its end furthest from the support points downwards toward the floor or upwards toward the ceiling. If a second rotation axis is provided, it is preferably oriented vertically. By rotating around this axis, the long section can then be moved, for example, from left to right or from right to left.

[0037] The invention also relates to a training device. This training device should have at least one vertical post, which has an attachment of the type described herein. This attachment should be mounted on the vertical post.

[0038] A training device with two parallel vertical posts and two attachments, each attached to a vertical post, is often advantageous. This makes it easy to set up a training device that is well-suited for training both the right and left sides of the body.

[0039] Also of interest is a training device that features two attachments, and thus two long pieces, each with a near-support and a far-support end. In such a training device, the attachments can be oriented so that the near-support ends of the long pieces are closer to each other than the far-support ends.

[0040] The invention also relates to a method which may comprise the following steps:

[0041] Providing a first post (12A) on which a first long piece (20A) having a first longitudinal axis is mounted, on which a first carriage (64A) is mounted which is movable along the first longitudinal axis against a tensile force.

[0042] - Providing a second post (12B) on which a second long piece (20B) having a second longitudinal axis is mounted, on which a second carriage (64B) is mounted, which is movable along the second longitudinal axis against a tensile force, wherein the position of the first long piece (20A) is adjustable relative to the second long piece (20B),

[0043] - Moving the first carriage with the right arm against the pulling force,

[0044] - Move the second carriage with the left arm against the pulling force.

[0045] In particular, a method may be of interest in which the end of the first long piece closest to the post is above the end of the first long piece far from the post, and the end of the second long piece closest to the post is also above the end of the second long piece far from the post. In this method, the ends of the long piece far from the post point downwards. Furthermore, the distance between the ends of the long pieces far from the post can be smaller than the distance between the ends of the long pieces near the post. The slides mounted on the long pieces can then be pulled towards the body from bottom to top. In the process, the slides move apart, initially approximately a hand's width apart and then increasing to shoulder width.

[0046] It is also possible to use the attachment to perform a series of training sessions, each time using the long pieces in different positions. It is particularly useful to use a training bench as part of the method. If the user lies prone on the training bench, the training bench serves to support the chest. Otherwise, the training bench serves to support the back. Both uses of the training bench can be useful within the scope of the present invention.

[0047] Also of interest is a method in which the pulling force is directed so that it pulls the sled(s) toward the end of the long sections farthest from the post, while the sled is pulled by muscle power toward the end of the long sections closest to the post. For this muscle-training method, it is advisable for the trainee to support themselves with their chest on a training bench.

[0048] The method is to be understood as relating to the attachment according to the invention. This means that features of the design of the attachment are to be transferred analogously to the method, and features of the method are to be transferred analogously to features of the attachment.

[0049] Further features, as well as advantages of the invention, will become apparent from the following drawings and the accompanying description. In the figures and the accompanying descriptions, features of the invention are described in combination. However, these features can also be encompassed by a subject matter according to the invention in other combinations. Each disclosed feature is therefore also to be considered as disclosed in technically reasonable combinations with other features. Some of the figures are slightly simplified and schematic.

[0063] Fig. 1 shows a training device that can be equipped with all the features of the present invention, but is not yet equipped in this variant. Two attachments are shown mounted on a training rack in a perspective view. The first attachment 10A is visible on the right, and the attachment 10B on the left. The first attachment 10A is mounted on the first front post 12A, and the second attachment 10B is mounted on the second front post 12B. The posts 12A and 12B, together with the rear posts 14A and 14B, form four posts of a training rack. These posts are connected by upper cross braces 16 and lower cross braces 18. Training racks of this type are widespread and also popular with home users. The first attachment 10A comprises a movable arm 20A. This is mounted on a joint 22A. The joint is mounted on the first post 12A with the sleeve 24A.

[0064] Attachment 10A also features a handle 26A. This handle allows for a variety of physical exercises, but does not need to be mounted. Attachment 10A also features a mandrel 28A. This mandrel can accommodate additional weight plates, but this is not required. Mandrel 28A also does not need to be mounted on arm 20A.

[0065] At the end of the arm 20A is a pulley 30A, which can guide a pulley cable 32A. The pulley cable 32A is guided from the pulley 30A along the training rack to the weights 34A. The pulley cable is not guided to a carriage in this training device, so the invention is not illustrated here. However, a minor modification can produce an attachment and training device according to the invention. Conversely, with an attachment and training device according to the invention, it is often advantageous to detach the pulley cable from the carriage and use it for other muscle exercises.

[0066] The training frame also features lower front outriggers 36A and 36B. These allow for alternative routing of the pull rope. The rope guides 38A and 38B are provided for this purpose. The training frame also features lower upper outriggers 36C and 36D. These allow for even further alternative routing of the pull rope. The rope guides 38C and 38D are provided for this purpose.

[0067] This illustration also clearly shows the routing of the traction cable 32. A traction cable section 32A is connected to the weight block 34A. The traction cable is guided, among other things, over the upper deflection pulley 48. From this deflection pulley, the traction cable is guided to the feed pulley 50, which is located on the sleeve 24 and can guide the traction cable to the movable arm 20A. Another section of the traction cable is guided upwards by the lower deflection pulley 52. ​​This traction cable section is also guided to the sleeve 24. By providing at least one upper deflection pulley 48 and at least one lower deflection pulley 52, it is possible to form a cable loop in which a tensile force of the same magnitude acts upwards from the upper deflection pulley and downwards from the lower deflection pulley 52. ​​By having the same tensile forces acting on the sleeve 24 from above and below, it is possible to move the sleeve up or down along the post 12A against very little resistance.

[0068] Fig. 2 shows in an enlarged view the suspension and guidance of a movable arm, namely, for example, the movable arm 20A, which is guided on the post 12A.

[0069] The sleeve 24 serves to connect the arm 20A to the post 12A. This sleeve has the support plate 40. The support plate 40 supports the side wall 42A and the opposite side wall 42C. These side walls, in turn, support the axis 44, which guides the movable arm 20A. Rows of holes are provided on the side walls 42A and 42C. With a corresponding bolt, the angular movement of the arm around the axis 44 can be slightly limited upwards or downwards.

[0070] The side panels 42A and 42C are held by the base plate 54. The base plate 54 is rotatable relative to the support plate 40 about a (not visible) rotation axis. By rotating the base plate 54, the axis 44 can be moved from the horizontal (about a not visible positioning axis, for example in the form of a bolt). The base plate 54 also has a row of holes 56 to fix the axis 44 in the selected position. The base plate 54 also has the cable guide 58. This allows the traction cable 32 to be guided from the rear to the movable arm 20A and also through the movable arm to the user-side end of the arm.

[0071] The pull rope 32 does not have to be offered as a single piece; it can also be offered in multiple pieces. In particular, it is possible to route only one pull rope through the arm 20A, but to provide the weight load through several pull rope sections and pull rope loops. It is possible to route a rope loop through the arm 20A, but this is not always necessary.

[0072] In this respect, a second rope passage can be provided in addition to the rope passage 58 shown, or two ropes or two ends of a loop can be guided through the rope passage 58.

[0073] The collar 24 of the attachment is formed not only by the support plate 40 but also by the rear plate 60. These plates can enclose the post 12A like a sandwich. The two plates can be connected by connecting bolts to form a collar enclosing the post 12A. The upper outer connecting bolt 62A and the lower outer connecting bolt 62B are visible here. By using such connecting bolts, the distance between the support plate 40 and the rear plate 60 can be easily adjusted to the post dimensions.

[0074] Fig. 3 shows a training device according to the invention. This comprises a frame and in particular the vertical posts 12A, 12B, 14A and 14B (the other frame parts correspond to the illustration in Fig. 1 , although in this variant the outriggers 36 are not used). The training frame has weights 34A and 34B which are connected to the attachments 10A and 10B via various pull cable sections, such as the pull cable sections 32A and 32B. The attachment 10A has an arm 20A in a known manner and the attachment 10B has the arm 20B. These arms are movably connected to the posts 12A and 12B in the manner already shown. In this embodiment, the arm 20A is connected to the carriage 64A and the arm 20B is connected to the carriage 64B. The carriages can move back and forth on the arms. The carriage 64A carries the handle 26A and the mandrel 28A. The carriage 64B carries the handle 26B and the mandrel 28B.The aforementioned mandrels can be used to hold additional weights, but they can also be omitted entirely. In a manner described in more detail later, the sleds are connected with pull rope sections. This allows the pulling force imparted by the pull rope to counteract the movement of the sled. The high mobility of the attachments 10A and 10B relative to the vertical posts and the ability to move the sleds in both directions against a pulling force allow for a wide variety of training options.

[0075] Fig. 4 shows an attachment according to the invention in an enlarged view. Attachment 10A is shown in a perspective view, approximately as it would appear when looking at attachment 10A from the direction of attachment 10B.

[0076] The attachment includes the movable arm 20A, which is movably suspended by the joint 22A. The arm can be secured using the rows of holes in the side panels 42. The movable arm is supported by the sleeve 24A, which allows attachment to the post 12A.

[0077] A section of the traction cable 32 is guided into the arm through a feed roller (not further specified). This traction cable section runs in the inner cavity of the movable arm 20A. It is guided out of the arm at the end of the arm and connected to the carriage 64A. In addition to the mandrel 28A, this carriage again has the handle 26A, with which the carriage 64A can be pulled against the force of the traction cable to the end of the arm 24A near the post, i.e., in the direction of the joint 22A. Not visible, but necessary for the free selection of the position of the arm 20A in space, is another joint that allows movement perpendicular to the axis of the joint 22A.

[0078] The details of the traction cable guide are shown enlarged in Fig. 5. According to the invention, two identically constructed attachments are generally used. The more detailed construction of the carriage is shown by way of example with a perspective view of the attachment 10B from Fig. 3. The structural details correspond entirely to the attachment 10A. The attachment 10B has a movable arm 20B along which the carriage 64B runs. The carriage has an upper guide plate 66 and a lower guide plate 68 arranged opposite. The two guide plates are connected to one another by connecting bolts 70. These bolts themselves carry rollers with which the carriage 68B can travel along the arm 20B. The carriage further comprises a side element 72. The locking bolt 74 is provided on this side element. With the help of this locking bolt, the carriage could be fixed in recesses in the arm 20B.This fixation can be used to connect the carriage to the pull rope or to detach the pull rope from the carriage. During training, locking is obviously not provided. The carriage 64B also has upper rollers 76 and lower rollers 78, with which it is supported on the top and bottom of the arm 20B. The provision of numerous rollers allows for easy and precise guidance of the carriage on the arm, even when considerable forces are applied.

[0079] The handle holder 80 is mounted on the top side of the slide 64B. It serves, in particular, to hold the handle 26B. Furthermore, it carries the mandrel 28B. A locking pin 82 for the handle 26B is also provided on the handle holder 80. This makes it easy to change the position of the handle. Particularly with curved handles, rotating the handle around the central axis of the holding sleeve can be useful. Other adjustment options for the handle can also generally be useful within the scope of the present invention in order to always find an optimal handle position for different positions of the movable arms 20.

[0080] At the end (i.e., at the end remote from the device or near the user) of the movable arm 20B, a headpiece 84 is provided. The headpiece can be fixed to the arm or movable relative to the arm. In particular, the headpiece can be rotatable about the longitudinal axis of the movable arm. The headpiece has a deflection pulley 86. Opposite it also has a guide pulley 88. The pull rope section 90, which forms the end of the pull rope, is guided around the deflection pulley 86. The pull rope is guided through a 180-degree angle.

[0081] At the end of the traction cable section 90, a snap hook is provided, which can be connected to the eyelet 94 provided on the slide 64B. Furthermore, a stop element 96 is provided at the end of the traction cable section 90, which ensures that the traction cable section is not completely pulled into the movable arm.

[0082] Fig. 6 shows an attachment according to the invention in a different configuration. Attachment 10A is again shown. The perspective corresponds to that chosen for Fig. 4. In the already known manner, the movable arm 20A is connected to the joint 22A (and another joint not shown) with the sleeve 24A. This sleeve connects it to a post, here post 12A, of a training device. This training device also features the pull rope 32A.

[0083] The traction cable is guided from the end of the movable arm 20A closest to the post to the end remote from the post. It is expediently guided, as provided in this embodiment, through an internal cavity of the movable arm. At its end, the arm has the headpiece 84, whose guide roller 88 is used to redirect the traction cable. Accordingly, the traction cable section 90 is directed back toward the post 12A. The carabiner 92 provided for the traction cable section 90 is used to connect to a traction cable extension 98. The traction cable extension 98 is guided to the carriage 64A by means of the deflection roller 100. The deflection roller 100 is held by a retaining sleeve 102 that surrounds the movable arm. The deflection roller 100 is thus provided close to the post. By guiding the traction cable in this way, the carriage 64A moves away from the post (i.e. towards the head piece 84) against the tensile force of the traction cable.

[0084] Fig. 7 shows an enlarged view of an alternative embodiment of an attachment. The end of the movable arm 20, which is remote from the device, is visible. The headpiece 84 is located on this end. The traction cable is guided through the arm 20 and guided to the carriage 64 by means of the guide roller 88. For this purpose, a snap hook 92 is provided at the end of the traction cable section 90, which can be connected to the eyelet 94 of the carriage 64.

[0085] The carriage 64 comprises the base plate 110. The mandrel 28 and, opposite it, the handle 26 are conveniently attached to this base plate. An angle adjustment mechanism is provided for the handle 26, which is particularly clearly visible in this enlarged view. For this purpose, the joint 104 is provided on the handle. The handle can be fixed in various positions using the locking pin 106. For this purpose, the locking pin 106 engages the recesses of the locking plate 108.

[0086] Rollers are provided on the upper side of the base plate 110 of the carriage 64. In this case, four rollers are provided symmetrically, three of which are visible: rollers 112A, 112B, and 112C. The rollers are supported on a linear guide 114. This linear guide 114 is provided parallel to the movable arm on its underside and can run essentially over the entire length of the movable arm 20. The linear guide 114 can consist of one, two, or more guide elements. In this case, two parallel guide elements are provided: two round rods 116A and 116B, the ends of which are visible. Such round cross-sections are generally preferred. Hollow or solid rods made of metal, in particular stainless steel, are expedient. The rods are attached to the movable arm 20 by a holder 118 that also runs longitudinally.

[0087] Two rollers are provided on either side of the linear guide 114, so that two rollers are supported on each rod of the linear guide 114. The rollers have a hollow profile with which they essentially move along the outside of the corresponding rods in a form-fitting manner.

[0088] Fig. 8 shows an enlarged view of another embodiment of an attachment. Again, the end of the movable arm 20 remote from the device is shown. This has the head piece 84, whose guide roller 88 guides the traction cable 32 and in particular its cable section 90 to the carriage 64. The carriage in turn has a base plate 110. This base plate runs on the upper side of the movable arm 20. Opposite it is a counter plate 120. The two plates 110 and 120 are connected by four bolts. These bolts also serve as axles for rollers. The two front rollers 112A and 112B are clearly visible. A linear guide is provided for these rollers, which is connected to the movable arm 20. In this case, a first rod profile 122A is provided on the left side of the movable arm 20 and a second rod profile 122B is provided on the right (generally: opposite) side of the movable arm 20.These profiles provide a mount with a roughly triangular cross-section, which can be formed into a single piece semicircular profile (a two-piece design is also possible). The rollers run along the surface of the semicircular profiles in a similar manner to the previous design. For this purpose, the rollers can have a round, hollow shape, allowing them to slide smoothly along the linear guide.

[0089] Fig. 9 shows, in a similarly enlarged view, yet another embodiment of a suitable movable arm. Again, the traction cable 32 is guided through the inner cavity of the movable arm 20. The traction cable then reaches the head piece 84 and is deflected around the guide roller 88, so that the traction cable section 90 is oriented toward the carriage 64. The carriage 64 again has a base plate 110. This base plate is provided with two side cheeks, the left side cheek 124A and the right side cheek 124B. A counter plate can also be expediently provided below the movable arm 20. The side cheeks 124A and 124B here carry both the mandrel 28 and the handle 26. The handle again has a joint 104 and a locking pin 106, which interacts with the locking plate 108.Via the joint 104, the handle 26 can be connected to a rod which is guided in a sleeve of the slide 64 and also supports the mandrel 28.

[0090] In this case, two rod profiles are again provided on the movable arm 20 as the linear guide, namely the rod profile 122A on the left side of the arm and the rod profile 122B on the right side of the arm. In this design, linear slides 124A and 124B are provided. Such linear slides comprise linear guides for contact with the rods (or generally guide or slide rails). The linear guides often use linear ball bearings. The bearing arrangement is essentially in the form of an annular ball bearing, enabling precise and very low-friction guidance. The corresponding guides are also marketed as linear blocks. This design makes it easy to achieve very low-friction guidance of the slide, which can be implemented using proven standard components (namely guide rails and bearing blocks / slides).

[0091] Fig. 10 shows another embodiment, in which a linear guide 114 is also used, which allows the carriage on the arm 20 to be guided particularly well. For this purpose, an additional rail, the rail 128, is mounted on the arm 20. This rail is designed as a double-groove guide rail. The rail can be provided either on the upper side of the arm (i.e., facing the ceiling) or on the underside of the arm (i.e., essentially facing the floor). The arm can also have two rails, which can serve to accommodate a carriage either in parallel or alternatively.

[0092] For this purpose, a slider 130 can be mounted on the rail 128. The slider 130 has a receptacle 132 for this rail. This receptacle has a cross-section adapted to the rail. The slider 130 is typically equipped with ball bearings to enable particularly smooth running on the rail. Opposing arrangements of five or more balls are expedient.

[0093] Such systems are readily available commercially as so-called linear guides. A rail 128 with two opposing grooves, here grooves 134A and 134B, both of which are trapezoidal, is suitable. Rails 128 that have an undercut area 136 as part of a groove are advantageous.

[0094] The rail 128 can be attached to the arm 20 with a plurality of bolts; accordingly, a plurality of receiving holes 138 for connectors and, in particular, bolts are provided on the top of the rail. The particularly smooth running of the slider 130 on the rail 128 enables a pleasant workout, in which the resistance depends largely on the adjustable weight load. For this purpose, the slider 130 is integrated into the carriage 64 and, in particular, carries the handle 26. Fastening elements for connecting to such components can be seen on the top of the slider 130.

[0095] A plurality of recessed openings 136 may be provided along the rail, which can accommodate connecting means, e.g. bolts, to establish the connection to the arm 20.

[0096] Fig. 11 shows a cross-section through the embodiment of Fig. 10, showing the component transverse to the longitudinal direction of the arm 20 and the rail 128. The slider 130 runs on the rail 128. Its receptacle 132 surrounds the rail 128 in a form-fitting manner. It is advantageous to provide undercuts in the rail profile for this purpose. In this case, these are undercuts 136A and 136B. These undercuts prevent the carriage 130 from detaching from the rail 128 and contribute significantly to the form-fitting connection of the carriage to the rail. This is important because high torques are exerted during strength training, including those transverse to the longitudinal axis, which could lead to the separation of the carriage 130 and the rail 128. Such a situation could be quite dangerous for the trainee.

[0097] Fig. 12 shows a cross-sectional view parallel to the cross-sectional view in Figure 11, but taken from a different location. In this case, one can see the attachment of the rail 128 to the arm 20 by means of a bolt 140. Furthermore, it is often advantageous if only one rail such as the rail 128 needs to be provided and if the slider 130 securely grips the rail but is open on one side. An angle of more than 180° but less than 300° is suitable for the gripping. Overall, one can see: With a convenient modification, the training device, which is available with an attachment, can be used for various exercises. The carriage can be moved away from or towards the post of a training device against the force of the pull rope. Until now, a variety of different training devices were required for such exercises.These can easily be provided in a gym, but the present invention offers considerable added value, especially for home users.
