Description

[0001] The present invention relates according to claim 1 to a training device which is designed for detachable attachment to a bar, in particular a training bar. Furthermore, the invention relates according to claim 13 to a set.

[0002] Weight training is one of the most widespread sports and is offered in almost all gyms. There are also sports clubs, recreational facilities, and private training equipment used for weight training. Standard equipment generally used includes dumbbells, barbells, pull-up bars, and horizontal bars.

[0003] The aforementioned exercise equipment has the disadvantage that the movement sequences they enable are very predefined, meaning only a few muscle groups are trained. This is disadvantageous for several reasons. For example, training is very time-consuming if all muscle groups are trained evenly. Furthermore, muscle injuries can result from muscle groups that are trained to different degrees of intensity if a training or life situation arises in which trained and untrained muscle groups are used together. This can overload the untrained muscle groups, which can lead to tears.

[0004] EP0449984A1 discloses an exercise device for attaching weights to a user's hand. The exercise device can be used in water for swimming or on land for jogging or other exercises. A weight is inserted into a pocket on a holder for placement on the back of the user's hand. A strap is attached across the pocket to hold the weight in place. The strap includes a first band with free ends for wrapping around the user's metacarpal bone. An auxiliary band runs at an angle from the first band to and around the inside of the user's wrist. The weight can be removed from the pocket to vary the load according to the desired muscle load. The exercise device may include multiple pockets for inserting multiple weights.

[0005] Furthermore, the following documents are known, some of which concern very different approaches in the field of strength sports: US 2009 / 0 275 448 A1, US 2009 / 0 275 447 A1, US 2019 / 0 009 125 A1, WO 2015 / 148 633 A1, US 9 522 298 B2, CN 1 11 111 093 A, DE 10 2018 128 262 B4, US 2015 / 0 306 443 A1, US 5 152 731 A, US 9 028 377 B2, US 2020 / 0 069 995 A1, US 4 978 122 A, US 2016 / 0 121 159 A1.

[0006] It is therefore the object of the present invention to provide a solution that enables strength athletes to exert a more complex muscle load during training, in particular when using dumbbells, barbells or pull-up bars.

[0007] The aforementioned object is achieved according to the invention by a training device according to claim 1. The training device according to the invention is designed, configured or constructed for detachable attachment to a bar, in particular a training bar, such as a dumbbell bar or a pull-up bar. The training device preferably has a guide-support structure, in particular a housing or a substrate. The guide-support structure has an inner side and an outer side for transmitting forces, wherein the inner side and the outer side are preferably coupled to one another in such a way that forces can be introduced into the guide-support structure via the outer side and transmitted to the inner side and / or wherein forces can be introduced into the guide-support structure via the inner side and transmitted to the outer side.A receiving area for receiving the rod can preferably be delimited or limited at least in sections by the inner side and can be enclosed at least in sections, in particular for the majority of the area, in the circumferential direction. The inner side particularly preferably has one or more movement components for bringing the rod into direct contact, wherein the movement component or the movement components are coupled to the guide-support structure at least indirectly, in particular directly, in a form-fitting, material-fitting, field-fitting and / or force-fitting manner, or wherein the movement component or the movement components are part of the guide-support structure. Particularly preferably, the movement component is designed to effect a rolling movement and / or a sliding movement, or the movement components are each designed to effect a rolling movement and / or a sliding movement.The outer side is particularly preferably designed for at least indirect, in particular direct, contact by a person.

[0008] The term "guiding-supporting structure" is used here according to Albers, A. (cf. "Basic design methodology model for the relationship between design and function of technical systems - The element model "Effective surface pairs & guiding-support structures" for the analysis and synthesis of technical systems." Albers, A.; Matthiesen, S. 2002. Konstruktion, 54 (7-8), 55-60.

[0009] The solution described above is advantageous because the training device can be coupled to bars, in particular training bars, and a relative movement can be generated between the training bar and the training device due to the movement component(s). The fixed arrangement of the hand on the training bar is thus eliminated, whereby the hand can be moved relative to the training bar in a rotational and / or axial direction, in particular displaced and / or pivoted. The present invention thus creates the possibility for the first time of increasing the degrees of freedom of movement during strength training, in particular using dumbbells, barbells or pull-up bars, and thereby enabling more complex movement sequences. These more complex movement sequences then ensure that muscle groups that could not be trained previously or could only be trained using another exercise are also trained.A bar, in particular a training bar, can also be understood as a tube or an elongated solid body, in particular made of metal, wood or plastic.

[0010] This solution is also advantageous because it eliminates the need for the person's hand to directly touch the bar, preventing the transmission of bacteria, viruses, or fungi. The present invention thus also makes a valuable contribution to improving hygiene in strength training.

[0011] Further preferred embodiments are the subject of one or more subclaims and / or the subject of the following parts of the description.

[0012] According to a preferred embodiment of the present invention, the movement components of the guide support structure are designed as movement component assemblies. Each movement component assembly preferably has a rod contact ball for contacting the rod, and each movement component assembly particularly preferably has a plurality of bearing balls for supporting the rod contact ball. The rod contact ball preferably interacts with the rod in the use configuration, contacting it on the one hand, and the rod contact ball preferably interacts with the plurality of bearing balls in the use configuration, contacting it on the other hand. This embodiment is advantageous because it enables a sufficiently smooth and fluid relative movement of the training device with respect to the rod, even under very high forces.

[0013] According to a further preferred embodiment of the present invention, each movement component assembly has an assembly housing. Each assembly housing preferably has wall portions, wherein the wall portions preferably delimit a receiving space at least in sections and particularly preferably for the majority of the wall portions. The bearing balls and the rod contact ball are preferably arranged in the receiving space, wherein preferably at least or exactly one wall portion has an opening, wherein a first rod contact ball portion of the rod contact ball protrudes through the opening out of the receiving space and wherein a second rod contact ball portion of the rod contact ball is arranged in the receiving space. The first rod contact ball portion is preferably smaller in volume than the second rod contact ball portion. Furthermore, the opening is preferably circular.This embodiment is advantageous because the individual assemblies can be manufactured separately and, for example, inserted into provided receiving recesses in the guide-support structure, thereby becoming part of the guide-support structure. Preferably, the individual movement component assemblies can be glued and / or clamped to the guide-support structure, i.e., the individual movement component assemblies and the guide-support structure can be coupled to one another in a materially bonded and / or force-fit manner.

[0014] According to a further preferred embodiment of the present invention, the bearing balls have a bearing ball diameter (Ld) and the rod contact balls have a rod contact ball diameter (Sd), wherein the rod contact ball diameter (Sd) is preferably larger than the bearing ball diameter (Ld).Furthermore, according to a further preferred embodiment of the present invention, at least three bearing balls are provided per movement component assembly, and the bearing ball diameter of the bearing balls preferably has a length that is less than 0.9 times the rod contact ball diameter, or less than 0.8 times the rod contact ball diameter, or less than 0.7 times the rod contact ball diameter, or less than 0.6 times the rod contact ball diameter, or less than 0.6 times the rod contact ball diameter, or less than 0.5 times the rod contact ball diameter, or less than 0.4 times the rod contact ball diameter, or less than 0.3 times the rod contact ball diameter.This design is advantageous because, even at very high forces, a sufficiently smooth and fluid relative movement of the training device relative to the bar is enabled, while still allowing a very low design, which means that the training device can also be used by people with small hands without restrictions.

[0015] According to a further preferred embodiment of the present invention, the first locking device is designed as a locking element that is at least partially rotatable or pivotable about a rotation axis. A front portion of the locking element is preferably formed in front of the rotation axis in the longitudinal direction of the locking element, and a rear portion of the locking element is preferably formed behind the rotation axis in the longitudinal direction of the locking element. The front portion of the locking element preferably has a positive-locking portion for positively coupling with the second locking device, and the rear portion of the locking element preferably has an actuating surface for introducing forces to transfer the locking element from a locked configuration to a non-locked configuration.This design is advantageous because it allows the training device to be safely transferred into a use configuration, and the use configuration can also be easily removed again. This is also possible under the condition of high force application.

[0016] According to a further preferred embodiment of the present invention, the locking element has at least one clamping element on the underside in the front portion, and preferably at least or exactly two clamping elements, to secure the locked configuration. This embodiment is advantageous because a repositioning of the hand or fingers on the training device, which may occur unconsciously during weight training, does not immediately lead to the cancellation of the usage configuration or to the dissolution of an operative connection established between the first locking device and the second locking device.

[0017] According to a further preferred embodiment of the present invention, the second locking device comprises a deformation guide for elastically deforming the clamping element(s). The deformation guide deforms the clamping element(s) in the locked configuration by no deformation, or by less than 80% or less than 50% of the maximum elastic deformation of the clamping element(s) that can be achieved by the deformation guide.

[0019] According to another preferred embodiment of the present invention, the average height of the first topography and the average height of the second topography lie on different planes.

[0077] After all of the above, it can be seen that the present invention thus relates to a training device 1 for detachable attachment to a training bar 3, in particular a barbell bar or pull-up bar.The training device 1 preferably has a guide-support structure 2, wherein the guide-support structure 2 has an inner side 6 and an outer side 8 for transmitting forces, wherein a receiving area 10 for receiving the training bar 3 can be delimited at least in sections by the inner side 6 and can be enclosed at least in sections, in particular mostly, in the circumferential direction U, and wherein the inner side 6 has one or more movement components 12a, 12b for bringing into direct contact with the training bar 3, wherein the movement component 12 or the movement components 12a, 12b are coupled to the guide-support structure 2 at least indirectly, in particular directly, in a form-fitting, material-fitting, field-fitting, and / or force-fitting manner.

The outer side 8 is designed for at least indirect, in particular direct, contact by a person.

[0078] The present invention is therefore preferably a mobile sports device, which particularly preferably consists of or is formed from two training devices or handles 1.

[0079] The two handles 1 function independently of one another and are preferably secured with a closure, in particular a locking device. The two handles are intended to surround a bar, in particular a metal training bar, and are preferably movable along the bar and / or around the bar. By using the handle, the otherwise fixed handle is decoupled from the barbell. The hands can slide freely from the inside to the outside and vice versa during the movement. This free sliding trains a multitude of additional muscles compared to conventional use with a fixed handle on the bar. Since, in contrast to the hip, the human shoulder joints are largely stabilized by a multitude of muscles, this new training supplement offers a significant training advantage.

[0080] The device is designed for mobile use in gyms or at home, as it can be attached to or removed from a barbell in seconds. Thanks to the internally arranged movement components, particularly balls, the handles glide or roll along the bar and can also rotate around themselves.

[0081] There are preferably notches for the fingers around the handles to ensure a comfortable grip. The handle preferably has a base body and a holding area formed thereon. The holding area is preferably made of a different material than the base body. The material of the holding area or areas is preferably softer than the material of the base body or bodies. The material of the holding area is preferably a cushioning material, in particular rubber, natural rubber or foam rubber. This material can preferably be easily wiped down and disinfected. By using the two handles during training, several muscle groups are used simultaneously. The development of various muscle groups that are not otherwise used is promoted and strengthened. The handles help with correct and proper exercise execution. Example bench press:

[0082] When performing a bench press, the two handles are secured around the barbell, and the arms spread apart as the weight is lowered. Thanks to the movement components, especially the balls, this is done very easily and without any particular effort. When the bar and weight are pushed out, the handles are pushed back together. This piece of sports equipment or training equipment can also be taken with you and mounted on an outdoor bar, allowing for several other training exercises, such as pull-ups or push-ups.

[0083] Another important advantage of using it is the hygiene aspect, as everyone has their own handles and therefore no costs for gloves.
