Description

Field of the invention

[0001] The present invention relates to a holder for a pull rope arm. It thus relates to the field of training equipment, since a pull rope arm according to the invention is generally intended for physical training. Strength training can be achieved by pulling on a rope end that is guided through the pull rope arm. Strength training in which the arm itself is moved is also conceivable. However, the pull rope arm can also be used for other purposes. Background of the invention

[0002] A wide variety of training methods and equipment are available. Some are optimized for use in sports facilities, such as commercial gyms. Other training devices, which are usually lighter and less expensive but also offer fewer features, are designed for home use.

[0003] 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.

[0004] 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.

[0005] 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.

[0006] The present invention aims to provide an efficient holder with which an attractive training device can be produced, which is also particularly suitable for home users.

[0007] This object is achieved by a holder according to claim 1. Advantageous further developments are specified in the subclaims. Further description

[0008] The invention relates to a mount for a pull rope arm. The pull rope arm is typically used as part of a training device. It can then be used for muscle training, for example, by pulling on the end of the rope against a weight. The mount can also be used for a pull rope arm that is moved during the training itself.

[0009] The bracket should be able to connect the traction cable arm to a suitable support. Typically, the traction cable arm is mounted to a post using the bracket according to the invention. Such a post can have a round or square cross-section; rectangular or square posts are frequently used, or more precisely, posts whose cross-section perpendicular to the main extension length is rectangular or square.

[0010] It is useful if the bracket can be attached to a support in various positions, i.e., at least in a first position or a second position. For example, the bracket can be attached to a post at different heights. Many posts commonly used in training areas have rows of holes; the bracket can be attached to these rows of holes using a pin that engages these holes, making it easy to select a variety of positions on the post at different heights.

[0011] Within the scope of the invention, a pull cable section is to be guided to the bracket. This section originates from a pull point. From this pull point, a pull is exerted. This can be achieved, for example, by weights. It is also possible to provide elastic elements to apply the pull. It is possible and often expedient to guide a pull cable in one piece from such weights to the pull cable arm and also to the end of the pull cable arm. However, it is also possible to provide multiple pull cable sections. The term "pulley cable section" can therefore also refer to a single-piece, complete pull cable.

[0012] The bracket should have a holding part and a guide part. It is often practical to design these as separate components, for example as separate components that can be connected and separated. The holding part of the bracket should fully or partially enclose the support or rest against it. As a rule, it is necessary for the bracket to touch the support at least tangentially. In the case of a support with a rectangular cross-section, the bracket will usually rest on at least one side. However, it is often also practical for the bracket to rest positively on two or more sides of the support. In particular, it can be useful to enclose a support (particularly one with a rectangular cross-section) on all four sides. In this case, the bracket forms a kind of sleeve for the support.

[0013] The support member can be equipped with fasteners to conveniently connect the bracket to the support. These fasteners can include screws, for example, to secure the bracket to a wall. Other fasteners include pins that can engage with recesses in a post.

[0014] Within the scope of the invention, the guide part should be provided next to the support. For example, to the right or left of the support, or in front of or behind it.

[0015] When a bracket is mounted on a support, the bracket defines the front of the support. It is often then appropriate to position the guide part to the side, i.e., to the right or left of the support. In individual cases, it may also be appropriate to position the guide part in front of the support, so that from a perspective, it is positioned between the support and the pull cable arm.

[0016] It is advisable to attach the pull rope arm to the guide part. This allows the support part to be optimized for connection to a support, and the guide part to be optimized for supporting the pull rope arm, in addition to passing through the pull rope section or pull rope.

[0017] It has proven useful for the pull rope arm to be rotatable about an axis. In particular, a horizontal axis is considered. Preferably, the pull rope arm can also be rotated 360 degrees about this axis.

[0018] Particularly useful is an arrangement in which a pull rope passage is provided on the guide part and the rotation axis of the pull rope arm runs within the pull rope passage. If the pull rope passage is designed as a tube, it is particularly useful to arrange the rotation axis on the central axis of this tube. However, it can also be offset from this axis. The rotation axis of the pull rope arm is usually determined and identifiable by the type of support; in cases of doubt, it can also be more clearly identified by mounting the pull rope arm without the pull rope arm being part of the support in question.

[0019] The guide section has a user-proximal end and a user-remote end. The pull rope lead-through usually has a user-proximal end and a user-remote end, respectively. The user-proximal end is oriented toward the user and thus usually also toward the pull rope arm. The user-remote end is opposite the arm. It is advisable to provide a feed roller at the user-remote end of the guide section (and usually the pull rope lead-through). This allows for low-friction and precisely defined guidance of the pull rope from the pull point to the bracket.

[0020] It is also useful for controlled and low-friction guidance of the traction cable if a pulley for the traction cable or a section of the traction cable is provided at the end closest to the user. Such a pulley allows the low-friction and controlled feeding of the traction cable section to the pull arm.

[0021] It is advisable to select the diameter of the pulley so that the traction cable is guided through the pulley arm at the same distance from at least two opposite walls, i.e., centrally. It is particularly useful to select the radius of the pulley so that it corresponds to half the width of the arm perpendicular to the pulley axis.

[0022] A particularly secure pulley guide is achieved by using a second pulley in addition to the first. The pulley axes are preferably parallel. Especially when the arm is rotatable and the pulley arm is to be used in a variety of positions, the provision of a second pulley ensures secure pulley guide in all positions.

[0023] It is also useful to provide a sleeve in the pull-rope bushing, and this sleeve can rotate within the pull-rope bushing, i.e., be pivotally mounted. When the arm rotates around the pull-rope bushing, it is desirable that no significant frictional forces occur in the pull-rope bushing. This can be achieved by using such a sleeve. The sleeve can be suitably mounted for this purpose, for example, with ball bearings.

[0024] It is often expedient to offer and / or deliver the mount not alone, but together with a pull rope arm, or at least to use it as a standalone unit. In this respect, a mount with a pull rope arm is also the subject of the present invention. The pull rope arm can also have an end closest to the user and an end farther from the user. It is expedient to also provide a guide roller at the end of the pull rope arm closest to the user. For example, during pulling exercises, the pull rope can be safely guided out of the end of the arm closest to the user.

[0025] It is not only expedient to use the holder according to the invention together with a pull rope arm, it is also expedient to offer and / or deliver it together with a support, or in any case to use it naturally. The combination of pull rope arm holder and support results in a training device. An even more versatile training device is obtained if two pull rope arms are used, for example, one pull rope arm for training the left side of the body and one pull rope arm for training the right side of the body. Very often, the arms are trained with pull rope arms, so that a left pull rope arm can be offered for training the left arm and a right pull rope arm for training the right arm.

[0026] It is expedient to offer the bracket together with a support in the form of a substantially vertical rectangular post. The rectangular cross-section is obtained in a horizontal plane. Such a post has a front, a back, an inner side, and an outer side. The front is oriented towards the pull cable arm. The inner and outer sides form the left and right sides of the post. If two posts are used for two pull cable arms in the manner described, the inner sides of the posts are oriented towards each other. The outer sides of the posts, however, are oriented away from each other.

[0027] It has proven particularly useful if the guide part is arranged on the outside of a post.

[0028] It is useful if the holder with the pull rope arm is height adjustable, i.e. if the end of the arm can be mounted at different heights on the post and / or can be moved up or down on the post when mounted. Preferably, the pulling force on the pulling rope is applied in such a way that it does not counteract any change in height. In this respect, a holder with the pull rope arm and also a training device are of interest where the pulling force does not have to be worked against when adjusting the height of the arm. This can be achieved in a variety of technical ways. In particular, by supplying the pulling force from two opposite directions, e.g. by guiding the pulling force partly via a first pull rope section from above to the end of the arm and the pulling force partly via a second pull rope section from below to the end of the arm.The pulling force can be split 50:50. The portion of the pulling force applied from above should ideally be between 40% and 70% of the total pulling force applied to the mount. Applying more than 50% of the pulling force from above, for example, 60%, can further facilitate the height adjustment of the mount.

[0029] For this purpose, it has also proven useful within the scope of the present invention to guide the traction rope in a loop to the arm. One end of the loop is guided over an upper pulley and one end of the loop is guided over a lower pulley. The rope can be guided into the arm through pulleys. The loop can also be guided all the way to the user's end of the arm. A connecting element, such as a handle, can also be provided on the loop. Designing the traction rope as a loop, which is guided partly at the top and partly at the bottom, means that a pulley on the arm moves along the loop without any weight force being exerted. The traction rope can be made up of several pieces, and a loop can be connected using simple rope sections.

[0030] If the pull rope were guided downwards only and the pull rope was subjected to a corresponding weight load, an upward adjustment of the arm would only be possible against the force of gravity. In practice, the weights would then usually be removed from a weight holder before adjusting the arm, provided that one is provided in the system.

[0031] 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 may also be encompassed by an inventive subject matter in other combinations. Each disclosed feature is therefore also to be considered as disclosed in technically expedient combinations with other features. Some of the figures are slightly simplified and schematic. Fig. 1 shows a perspective view of two brackets according to the invention with which pull rope arms are mounted to a training rack Fig. 2 shows the same training device formed with two brackets in a frontal view Fig. 3 shows this training device in a side view Fig. 4 shows the training device in a first usage position Fig. 5 shows the training device in a second usage position Fig. 6 shows a plan view of a holder according to the invention for a pull rope arm, which is mounted on a post Fig. Figure 7 shows a front view of a bracket according to the invention for a pull rope arm mounted on a post Fig. 8 shows the same bracket in a rear view Fig. 9 shows the same bracket in a side view, showing the inside of the bracket Fig. 10 shows the same bracket in a sectioned side view, looking at the outside of the bracket

[0032] Fig. Figure 1 shows two brackets according to the invention in a perspective view. These support pull rope arms and, together with these, form attachments mounted on a training rack. 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.

[0033] The first attachment 10A comprises a pull-rope arm or movable arm 20A. This is mounted on a joint 22A. The joint is mounted on the first post 12A with the bracket in the form of the sleeve 24A.

[0034] 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.

[0035] At the end of 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.

[0036] 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.

[0037] Fig. Figure 2 shows the training device from the front. The view shows the right front post 12A and the left front post 12B. An upper cross brace 16 and a lower cross brace 18 are visible. Attachment 10A, which provides the movable arm 20A, is mounted on the right front post 12A. Attachment 10B, which provides the movable arm 20B, is mounted on the left front post 12B. The attachments are each mounted on support plates, plates 40A and 40B. Side panels are used for assembly, namely the outer side panel 42A and the inner side panel 42C for the movable arm 20A. Similarly, the outer side panel 42B and the inner side panel 42D are used for the movable arm 20B.

[0038] Fig. Figure 3 shows a side view of the training device. The view is of the right front post 12A and the right rear post 14A. The structure, consisting of these posts and unspecified cross braces, is extended forward by the lower boom 36A and the corresponding upper boom 36C. These booms each carry cable guides: the lower one carries the cable guide 38A and the upper one carries the cable guide 38C. The movable arm 20A of the attachment 10A is held by the horizontally extending axis 44. The arm 20A can move in a vertical plane around this axis. The post 12A also lies (at least partially) in this plane.

[0039] The holder in the form of the sleeve 24, which connects the attachment 10A to the post 12A, is height-adjustable on this post. It can be secured by connecting it to various recesses in the post 12A. For this purpose, the locking pin 46 is connected to the sleeve 24. Further height adjustment is provided by the row of holes in the side panel 42A. This row of holes allows the arm to be fixed in a specific angular position. The arm then drops down to the specified position and can be raised from this position. Alternatively, the upward angular movement of the arm can also be limited. Using the row of holes in the side panel 42A, the upper angular position of the arm can also be fixed. The arm can then be moved downward from this position for appropriate muscle exercises.

[0040] 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 (not visible as a component in this side view, but recognizable by its function). 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 applying equal tensile forces to the cuff 24 from above and below, it is possible to move the cuff up or down along the post 12A against very little resistance.

[0041] Fig. Figure 4 shows a perspective view of a training device. Only the essential elements of the device are provided with reference numerals. The posts 12A, 12B, 14A, and 14B provide a frame. Two attachments according to the invention are mounted to this frame: attachment 10A on the right and attachment 10B on the left. The movable arms 20A and 20B extend from the sleeves 24A and 24B, respectively. At the end of the arms, the handle 64A and the handle 64B are connected to the pull rope. The weight 34A is pulled upwards against a tensile force using the handle 64A, and the weight 34B is pulled upwards using the handle 64B.

[0042] Both arms are movable in a vertical plane. They can be moved parallel to each other. The movement axes of arms 44A and 44B are accordingly oriented horizontally. These movement axes 44A and 44B are mounted approximately at chest height. The arms extend upward from these axes, so that the handles 64A and 64B are approximately at head height or above. Both arms can be fixed in this orientation (for this purpose, the described perforated plates of the side panels and corresponding bolts are used).

[0043] This setup is suitable for muscle exercises in which the shoulder area in particular is trained through pulling movements from top to bottom.

[0044] Fig. Figure 5 shows a training device with holders according to the invention in a different configuration. The movable arms 20A and 20B are mounted on holders in the form of cuffs 24A and 24B. The cuffs and the axes 44A and 44B provided on the cuffs are again mounted approximately at chest height. This time, however, the axes are not aligned horizontally. Accordingly, the arms 20A and 20B are moved out of the vertical planes. More precisely, the arm 20A is tilted outward from the vertical plane marked by the posts 12A and 14A. In this case, outward means to the right, i.e., such that the distance of the user-side arm end relative to the other arm 20B is increased. The arm 20B is tilted accordingly, i.e., to the left. Like the arms, the axes can be fixed in this position. For this purpose, rows of holes with engaging bolts are provided.

[0045] The arms are also oriented upwards, accordingly the handles 64A and 64B are located above the cuffs and approximately at head or shoulder height.

[0046] In this configuration, the pull rope arms mounted on the supports allow for a different muscle workout. Again, the handles are pulled toward the body, but the direction of pull is not only from top to bottom, but also from outside to inside. Inside refers to locations approximately mid-plane between the left vertical plane, marked by posts 12B and 14B, and the right vertical plane, marked by posts 12A and 14A. Accordingly, different muscles are engaged and efficiently trained.

[0047] Fig. Figure 6 shows a top view of a mounting according to the invention. The mounting comprises a guide part and a holding part, the holding part being offered in the form of the sleeve 24A. The mounting essentially corresponds to the one used on the right post, post 12A, in Fig. 5. The position of the pull cable arm 20A also corresponds to the position of the arm shown there. In detail, the bracket 10 of the Fig. 6 a slightly different design than the bracket in Fig. 5. However, the basic elements correspond to each other.

[0048] In addition to the holding part in the form of the sleeve 24A, a guide part is provided on the holder. The pull cable 32 is fed to this guide part. The guide part itself is concealed in this view by the fixing disc 56. This fixing disc offers a plurality of holes into which the locking pin 58 can engage. In this way, the position of the arm 20A can be fixed relative to a rotation axis protruding from the plane of the paper. The passage 60 is provided in the area of ​​this rotation axis. The cable 32 (or a cable section) is guided through this passage to the arm 20A. The cable is guided to the end of the arm so that one end of the cable 62 protrudes from the end of the arm closest to the user.

[0049] Fig. 7 shows the Fig. 6, a top view of the bracket shown. It is mounted on the post 12A and supports the arm 20A. In this illustration, this arm 20A is directed vertically downwards so that it runs parallel to the post 12A. The arm is in turn held by the bracket 10 and in particular by the sleeve 24A, which serves as a holding part. The view again turns to the fixing disc 56. Corresponding to the different position of the arm 20A, the position of the locking bolt 58 has also changed. The cable 32 is guided through the clearly visible passage 60 into the open end of the arm 20A, remote from the user.

[0050] The cuff 24A consists of a large number of individual parts, of which the front plate 64 is visible here.

[0051] Fig. 8 shows one of the Fig. 7 shows a corresponding view from the opposite direction. Accordingly, one sees the rear side of the bracket 10, which includes the sleeve 24A as a holding part and additional parts located to the left of the post 12A as guide parts. The view is directed to the rear plate 66 of the sleeve 24A.

[0052] On the left side of the back plate 66, an annular support member 68 is provided for the cable guide 70. This support member 68 can also support the pivot axis for the arm 20A. It thus forms an essential part of the guide portion of the bracket 10.

[0053] Fig. Figure 9 shows a further top view of the holder according to the invention in the already known assembled configuration. The view is towards the inside, that is, the side which in the situation of Fig. 5 faces a corresponding arm 20A.

[0054] Clearly visible in this side view are the connecting bolts 72 that connect the front plate 64 and the rear plate 66. In this way, a holding part for a bracket can easily be formed from two plates and a number of bolts. Also shown is the locking bolt 74, which can engage in recesses in the post 12A to achieve easy height adjustment of the sleeve 24A.

[0055] The fixing cheek 76 is also clearly visible in this view. When the arm is rotated about the horizontal axis 44, it can be fixed using the fixing cheek 76, or more precisely, the holes and corresponding bolts provided therein.

[0056] This view also clearly shows the guidance of the traction cable 32 by means of the feed roller 50. The cable is fed largely vertically from above and then deflected by 90 degrees by means of the feed roller 50 and fed to the bushing 70.

[0057] Fig. 10 shows a side view from the opposite side, i.e., from the outside. However, this view is a sectional view, which allows the precise cable routing to be seen more clearly. The cable 32 is guided over the feed roller 50 to the feedthrough 70. It then runs through a channel in which a sleeve 78 is provided on the inside. From there, the cable is guided to a first deflection roller 80. To make the cable guidance even more precise, a second deflection roller 82 is provided opposite. From there, the pull cable section 84 is guided centrally in the arm 20A. It exits centrally from the end of the arm closest to the user, where a first guide roller 86 and a second guide roller 88 are provided for further guidance. In this way, the cable end is easily grasped.

[0058] Overall, it is clear how a practical device suitable for mass production can be produced inexpensively and universally applicable.
