Description

The invention relates to a sports arrangement.

Such a sports arrangement comprises a box body, a box body holder, a holding arrangement for holding the box body holder. The holding arrangement and the box body receptacle are set up in such a way that they hold the box body in a basic position. During the intended use, the box body is elastically displaced from the basic position by the action of a boxing blow and is then returned to the basic position. Such an arrangement can be formed in particular by a punching ball arrangement, a punching bag arrangement or a double end ball arrangement. Such a sports arrangement is in the German patent application 10 2019 002 702.7 and the PCT / EP2021/060474 described.

It is the object of the present invention to further develop the aforementioned arrangement. This is solved by a sports arrangement according to claim 1; Configurations are the subject of the dependent claims and the description.

The sports arrangement according to the invention comprises in particular: a box body, a tensioning cable, a first, in particular upper, attachment, a second, in particular lower, attachment, the tensioning cable being clamped between the two attachments. The tightening cable interacts with the box body in such a way that the box body is held in a basic position and that the box body can be displaced, in particular elastically, from the basic position by the action of a boxing blow and then returned to the basic position. The sports arrangement is set up for selectively adjusting a tension of the tensioning cable and/or the position of the box body on the tensioning cable. Furthermore, the sports arrangement can include a tension measuring device for detecting the cable tension of the tensioning cable. The box body is held in particular on a first rope section.

The sports arrangement according to the invention enables adaptation to the individual requirements of the user, in particular with regard to the sporting ambitions and the physical requirements of the user.

Proper rope tension is an important prerequisite for proper and successful use of the sports arrangement. It has been found that the intuitive adjustment of the rope tension by a user often leads to an adjustment that is not optimal from a sporting point of view. Using a tension measuring device, the cable tension can always be set precisely to an optimal default value, which can differ significantly from an intuitive setting by the user.

In one embodiment, the tension measuring device can be selectively coupled to a first cable section and selectively decoupled, so that the tension is passed through from the first cable section to the tension measuring device. The result of this is that the tension measuring device is only subjected to the tension of the tensioning cable when the tension is actually desired to be queried. In the normal operating mode, the tension measuring device can be decoupled from the first cable section, in particular decoupled from the tension of the first cable section, which supports its longevity. This avoids the sometimes sensitive components being exposed to a constant alternating load, which is generated by the constant vibrations of the tension cable.

Tension is the mechanical tension of the tensioning cable.

In one embodiment, the tensioning cable has at least a first cable section on which the box body is held. A cable clamp arrangement is arranged between the tension measuring device and the first cable section, the tension measuring device being decoupled from the cable tension of the first cable section in a clamping state of the cable clamping arrangement and the tension measuring device being coupled to the cable tension of the first cable section in a release state.

In one embodiment, the tensioning cable has a second cable section, with the cable clamping arrangement being arranged between the first cable section and the second cable section. The second cable section is connected to the tension measuring device via a connector. Consequently, the tension measuring device can be temporarily coupled to the second cable section with the tension on the first cable section.

In one embodiment, the connector is a rope clamp that can be moved freely with respect to the lower attachment and can be arranged at different positions on the tensioning rope. The cable clamp is set up to transfer a cable force from the tensioning cable to the tension measuring device. In particular, by moving the cable clamp along the tensioning cable, the length of the first cable section and thus the cable tension can be changed.

However, the connector only serves to transfer the cable tension to the tension measuring device during the release state of the cable clamp. The rope clamp can be designed to be self-locking, in particular such that the rope clamp exerts a first clamping force on the tensioning rope, with the first clamping force counteracting a slipping of the rope in the direction of the first rope section.

• - einen Griff, insbesondere einen Drehgriff,
• - ein Klemmstück,
• - sowie ein Gegenstück.

The cable clamp arrangement has in particular:

• - a handle, in particular a rotary handle,
• - a clamp,
• - as well as a counterpart.

By actuating the handle by a user, the clamping piece can be selectively transferred between the clamping state and the release state, with the tensioning cable being clamped between the clamping piece and the counterpart in the clamping state.

In one embodiment, the handle is a rotary handle and has a slotted guide. The clamping piece includes a guide projection which is in engagement with the guide link. The guide link interacts with the guide projection in such a way that rotating the rotary handle in a first direction of rotation causes the clamping piece to be transferred from the released state to the clamped state, and that rotating the rotary handle in a second direction of rotation causes the clamping piece to be transferred from the clamped state to the released state . The rotary handle enables a space-saving design of the cable clamp arrangement, with a transmission gear to increase the actuating force of a user being able to be accommodated in a space-saving manner. In this case, the transmission gear is the arrangement of guide link and guide projection.

In one embodiment, the box body includes an outer body and a base body. The base body is received in a receiving space formed by the outer body. At least one radially protruding securing projection is provided, in particular on the base body, which engages with a securing groove, in particular on the outer body, and is in particular set up to bring about a positive connection between the base body and the outer body. The form-fitting connection is in particular designed in such a way as to counteract a displacement of the outer body in relation to the basic housing.

In one configuration, the outer body has a surface with a wavy structure. In particular, the wavy structure causes improved adhesion when hitting and can thus counteract slipping of the hitting hand or boxing glove when hitting. The invention can also relate to a use of the sports arrangement.

In one embodiment, the adjustment means are means for tool-free loosening and fixing of the tensioning cable relative to the box body and/or relative to the upper attachment or relative to the lower attachment.

The 1 shows a sports arrangement 1, which is based on the patent applications mentioned above. This includes a box body 2 which is held by a tensioning cable 3 . The tension cable 3 is clamped between a first upper attachment 4 and a second lower attachment 5 . The sports arrangement 1 also includes an electronic terminal 8 for operation. The electronic terminal 8 can be a mobile phone or a tablet PC. The box body can by a Boxing punch, represented here stylized by a boxing glove.

The upper attachment can be screwed to a ceiling, a beam or other static element. Alternatively, the upper attachment can be glued to the ceiling, etc. The structure of the upper attachment can correspond to that in the patent applications described in the opening paragraph.

The 2 until 6 are described together and show an embodiment of the lower attachment 5 or parts thereof. The cable tension of the tensioning cable 3 can be adjusted using the second attachment 5 .

The second attachment 5 includes a base 51 with a correspondingly large weight of about 3-3.5 kg, which can provide the required stability. As an alternative to the base 51, the second attachment 5 can also be attached firmly to the floor or to a frame.

A clamp housing 52 is attached to the stand 51 . The tension cable 3 is passed through the clamp housing 52 and using a cable clamp arrangement 53 ( 3 ) attached. The rope clamping arrangement 53 comprises a movable clamping piece 53H, here in the form of a pivotable lever, and a counterpart 53G. The tension cable 3 can be clamped between the clamping piece 53H and the counterpart 53G and thereby fixed. The cable clamp arrangement 53 also includes a rotatable handle 53D, which at the same time as a cover closes the clamp housing 52 at the top. The tether 3 is threaded through an opening 530 in the handle 53D (shown in FIG 7 ) passed through.

The cable clamp arrangement 53 divides the tensioning cable 3 into two cable sections 31, 32. A first rope portion 31 is interposed between the box body 2 and the clamp piece 53H. A second cable section 22 is arranged on the other side of the clamping piece 53H. The second rope section 32 is gripped by a user. The user then pulls on the second rope section 32 and can put the first rope section 31 under tension. The clamping piece 53H is loosened for this purpose. Once the desired tension has been reached, the clamping piece 53H is brought into a clamping state and the rope tension is permanently set on the first rope section 31. Now the user can let go of the second rope section 32 and the tension on the second rope section 32 is eliminated. The second rope section 32 can then be wrapped around a winding section 54 . A shield 55 prevents the second rope section 32 from unwinding undesirably. The free end of the second rope section 32 can be clamped on the shield 55 .

When the clamping piece 53H ( 3 ) the cable tension of the tensioning cable 3 is determined using a tension measuring arrangement 56 . The tension measuring arrangement 56 comprises a tension measuring device 561. The tension measuring device can have a deformable element which is deformed depending on the rope tension. The deformation can be recorded electronically, which is the basis for calculating the cable tension using a computing unit. A tension connector 562 connects the second rope section 32 to the tension gauge 561. The tension connector 562 is a rope clamp 562 which can be placed on the tension gauge 561.

The strain gauge 561 is attached to a sensor housing 612 ( 6 ). A circuit board 613 with electronic components (not shown in detail) is arranged in an interior of the sensor housing 612 . The interior is closed with a cover 614 . At the same time, the cover serves as a battery housing and has a battery compartment into which a battery 615 for supplying energy to the voltage measuring arrangement is inserted. A seal 616 and another cover 617 close the battery compartment.

The rope clamp 562 is designed in relation to the tensioning rope 3 in such a way that it is held stationary on the tensioning rope 3 due to a clamping force. The cable clamp 561 is in contact with the tension measuring device 56 on the side of the second cable section 32 . For this purpose, an opening is formed on the tension measuring device 561 in such a way that the tensioning cable 3 can be fed through the opening, but the connector cannot be fed through. A cable force corresponding to the cable tension is thus transmitted from the tensioning cable to the tension measuring device 561 via the cable clamp 562 .

To change the cable tension, the position of the cable clamp 562 on the tension cable must first be changed. This can be done manually by the user.

In the event that the rope tension is to be reduced, the user pulls on the first rope section 31 . As long as the user is pulling on the first rope section 31 , the tensioning rope 3 slips through the rope clamp 562 until the user stops pulling on the first rope section 31 .

The cable clamp 562 is designed to be self-locking in the direction of the first cable section 31 , so that the tensioning cable is fundamentally prevented from escaping upwards in the direction of the first cable section 31 . However, the clamping force is limited and can - as explained above - be overcome by the corresponding tensile force of the user.

In the event that the rope tension is to be increased, the user pulls on the second rope section 32. The user must apply a force that overcomes the existing rope tension. The rope clamp 562 is not designed to be self-locking in the direction of the second rope section 32 . As soon as the user has overcome the cable tension, the cable clamp 562 first moves away from the tension measuring device 561. The user can then move the cable clamp 562 in the direction of the first cable section 31. By reducing the pulling force of the user on the second rope section 32, the rope clamp comes into contact with the tension measuring device 562 again.

The cable tension determined by the tension measuring arrangement can be displayed on the end device. As soon as the correct cable tension has been set, the tension cable 3 is fixed via the cable clamp arrangement 53 .

By locking the cable clamp arrangement 53, the tension measuring arrangement 56 is decoupled from the permanently tensioned first cable section 31 ( 4 ). Thus, in continuous operation, the voltage measuring arrangement is not subjected to the vibrations, which considerably reduces its susceptibility to wear.

The terminal housing 52 is designed in several parts and protrudes through a central opening of a base 51 . The base 51 is held in a form-fitting manner between an upper part 520 and a lower part 52U of the terminal housing 52 . For the connection, the upper part 520 is screwed to the lower part 52U. The upper part 520 and the lower part 82U each have an integrally formed thread; screwing is achieved by twisting the upper part relative to the lower part. The clamp housing 52 also has two lateral guide parts 52S, through which the second cable section 32 is guided outwards from the cable clamp arrangement 53 .

The clamping piece 53H is movably mounted. The clamping piece 53H can be pivoted from a released state ( 3 ) into a clamped state ( 4 ) and vice versa.

The clamp 235 is operated by the handle 53D. The handle 53D is rotatably supported with respect to the clamp case 52. As shown in FIG. On an inside, the handle 53D has a guide link 53F ( 7 ).

The guide link 53F acts with a guide projection 53V ( 3 and 4 ) on the clamping piece 53H together in such a way that a rotation of the guide link 53F causes a displacement of the guide projection 53V from radially inside to radially outside or vice versa. Viewed in a circumferential direction U, the guide link 53F widens radially. If the handle 53D is rotated along this circumferential direction U, the guide projection 53V is acted upon in the radially inward direction on the tensioning cable 3, as a result of which the clamping is effected. By turning the handle 53D counter to this circumferential direction U, the guide projection 53V can deviate radially outwards, as a result of which the clamping force is reduced or eliminated.

The strain gauge 561 includes an elastic force absorbing element, not shown in detail, which is connected to the strain connector 562 . The force absorbing element has a plurality of sensors which are suitable for detecting bending moments on the force absorbing element, from which the tensile force introduced can be derived. The force receiving element is attached to the sensor housing 612 .

The 8th shows the box body 2, which is designed in several parts, in an exploded view. The box body 2 comprises an outer body 21 which, in particular, forms the largest part of an outer surface 201 of the box body 2 . The outer body 21 is designed in such a way that the user experiences the desired haptic counter-reaction when executing a boxing punch. For this purpose, the outer body 21 has a certain ball-like flexibility. The outer body 21 can in particular be formed from a foamed material with a suitable surface finish.

The surface of the outer body has a wavy structure, which is a visual recognition feature. The wavy structure reduces the risk of slipping or slipping when the punching fist or boxing glove makes contact with the outer body, thus promoting a more precise punch.

The outer body 21 has a first accommodation space 211 . The first accommodating space 21 extends through the entire outer body 21 along a central axis M in the vertical direction. The central axis M is aligned coaxially with the tensioning cable 3 . The tension cable 3 is guided through the first accommodation space 211 .

Further components of the box body 2 are arranged in the first receiving space 211, in particular electronic components and components for adjusting the height of the box body.

A base housing 22 is accommodated in the first accommodation space 211 . The main housing 22 can essentially have a cylindrical shape, which can taper slightly from the axial bottom to the axial top. The basic housing 22 is formed from a solid plastic and can be connected to the outer body 21 in a material-to-material and/or form-fitting manner, for example.

In order for the basic housing 22 to be securely accommodated in the outer body 21, the basic housing 22 can have radially projecting securing projections 223 on an outer circumference, which together with the outer body 21 constitute a form-fitting safeguard against relative movement in the direction of the central axis M. The securing projections 223 are designed, for example, as circumferential securing ribs. Internal securing grooves 213 are provided on the outer body 21 and are positively engaged with the securing projections 223 .

For assembly, the outer body 21 is slipped onto the base body 22 from above until the securing projections 223 are securely in engagement 213 with the securing grooves 213 . These securing grooves 213 can be provided with a sloping contact surface which, on the one hand, makes it easier to remove the ball from a foaming tool and, on the other hand, makes it easier to mount the outer body on the basic housing. In addition to a positive connection, the ball can be glued to the housing.

Alternatively, the outer body 21 can be foamed around the base housing 22 .

The base housing 22 has a second receiving space 221 which extends through the base housing 22 along the central axis M and through which the tensioning cable 3 is passed. An insert housing 23 is inserted in the second receiving space 221 . The insert case 23 is detachably and movably arranged on the base case 22 .

The box body 2 includes an interaction element 29 which is arranged on an outer surface of the box body so that a user has access to the interaction element 29 .

The interaction element can support different MMI functions. In one embodiment, the interaction element 29 is a button with which a touch command can be transmitted to the electronic components in the receiving space. For this purpose, the interaction element is displaceable, in particular mounted in a displaceable manner. Even if the sports arrangement is operated largely wirelessly via the electronic terminal device, direct interaction may still be necessary, for example to start a pairing process or to switch the power supply on or off.

In one embodiment, which can also be combined with the previous embodiment, the interaction element 29 is designed as a light-guiding element. A light signal can in particular indicate the functionality of the sports arrangement 1 or the presence of the pairing process and/or provide information about a coupling status of the Bluetooth components or the battery status. The interaction element itself can comprise or be an LED.

An insert case 23 is disposed and fixed in a lower portion of the second accommodating space 221 . In the assembled state, the insert housing 23 closes the second receiving space 221. The insert housing 23 has a clamping guide 232 which is aligned along the central axis M. The tensioning cable 3 is passed through the clamping guide 232 .

A clamping lever 235 is movably mounted on the insert housing 23 . The clamping lever 235 can be pivoted from a release state ( 9a) into a stuck state ( 9b) and vice versa. In the clamping state, the clamping lever 235 clamps the cable guided in the clamping guide 232 and thus fixes the relative position of the insertion housing with respect to the tensioning cable.

When clamped, the box body can be fixed at a desired height on the tensioning cable. An adjustment of the height is possible in the release state, e.g. to adapt to the specific body size of different users.

The clamping lever 235 is actuated by an actuator. In the present example, the actuator is a lower cover 28. The actuator 28 is held on the insert housing 23 such that it can rotate. The actuator has a guide link 281 on an inner side. The guide link 281 interacts with a guide projection 236 on the actuator in such a way that a rotation of the guide link 281 causes a displacement of the clamping lever 235 between its clamping state and its release state. 10a shows the relative alignment of the actuator to the clamping lever 235 during the release state, 10b shows the relative orientation of the actuator 28 to the clamping lever 235 during the clamping condition. On an outside, the actuator 282 has a handle 282, in particular with two recessed grips, on which a user can twist the actuator. To open or close the handle is rotated by 90°, for example.

The actuator 28 also represents a housing cover on the underside of the base body and is arranged somewhat countersunk in the box body in order to avoid injuring the striking hand on any hard plastic edges. An edge of the outer body 21 protruding beyond the actuator and the base body serves as protection at this point.

Viewed in a circumferential direction U, the guide link 281 widens radially. If the actuator is rotated along this circumferential direction U, the guide projection 236 is acted upon radially inwardly on the tensioning cable 2, as a result of which the jamming is effected. For this purpose, the clamping lever has teeth on a surface that interacts with the tensioning cable, which increases the friction between the tensioning cable and the clamping lever. By turning the actuator counter to this circumferential direction U, the guide projection 236 and thus the clamping lever 235 can deviate radially, as a result of which the clamping force is reduced or eliminated.

An electronics mount 210 on which electronic components are arranged is also accommodated in the second accommodation space 221 .

8th FIG. 12 shows a battery 242 housed in a battery accommodating space 241. FIG. The battery accommodating space 241 is sealed by means of a seal, not shown. The battery receiving space 241 is formed by a removable battery case 241 .

The outer body 21 is formed in particular from a PUR foam. The remaining housing parts are made in particular from ABS plastic.

For assembly, the tension cable is hooked into the upper attachment 4. The upper attachment 4 is attached to the ceiling, for example. The tension cable 3 now hangs from the ceiling. The tensioning cable 3 is passed through the box body 2 . The rope clamping guide of the box body 2 is transferred to the clamped state, so that the box body 2 is now fixed to the tensioning rope 3 .

The clamp housing 52 is attached to the base 51 at the lower attachment 4 . The tension cable is passed through the cable clamp arrangement so that the second cable section 32 is led out again from the side parts 52S. The cable clamp arrangement 53 is in the release position. Now, from the second cable section 32, the cable clamp cable tensioner 562 is pulled onto the tension cable. The tensioning cable 3 is stretched over and then the cable clamp 562 is brought into contact with the tension measuring device 561 . The cable tension can now be determined using the tension measuring arrangement and displayed on the terminal device 8 . If the cable tension is too high, the user pulls the first cable section 31 manually, so that the second cable section 32 slips a little through the cable clamp 562 . If the cable tension is low, the user first pulls on the second cable section 31 and then pushes the cable clamp 562 a little further along the tension cable towards the tension measuring device 561 .

After the correct cable tension has been set, the cable clamp arrangement is transferred to the clamped state, as a result of which the cable tension is permanently fixed. The actuator is rotated by about 90°. The cable clamp 562 has no essential function for the sports arrangement from this moment on. The second rope end protruding from the side parts 52S is wound around the winding section and, if necessary, clamped on the shield.
