Description

[0001] The invention relates to a clamping bracket for the detachable fastening of objects, in particular training equipment such as pulleys, resistance bands, sling trainers or calisthenics equipment, to a frame leg of a frame, such as a door frame, comprising at least one clamping mechanism with at least two clamping arms, wherein at least one of the clamping arms can be clamped with force against the frame leg to fasten the clamping bracket.

[0002] Furthermore, the invention relates in an inventive manner to a training device, in particular a fitness device for training the human muscles, with a frame, such as a door frame, and at least one tensioning bracket for the detachable fastening of objects in the form of training equipment, such as a pulley, resistance band, sling trainer or calisthenics equipment, to at least one leg of the frame.

[0003] German patent DE 201 16 548 U1 discloses a mobile cable-pull training device in the form of a tension bracket for mobile installation in door frames. The training device comprises a vertically oriented bar that can be clamped vertically in a door frame between a horizontal section of the door jamb and the floor by means of a lever mechanism. The device is attached without additional connecting elements, and the clamping force depends on the weight attached to the cable; that is, the clamping forces of the device increase with increasing load. However, the design is complex, and clamping is only guaranteed when the training device is under load. Furthermore, the training device is not suitable for pulling loads from different directions.

[0004] Home fitness equipment for resistance training with a pulley system is also known; this equipment is attached to the ceiling by drilling a hole. Drilling into the ceiling has the following disadvantages: • Complex installation • Ceiling mounting can be challenging. Suitable fixing points must be found to ensure the ceiling can withstand the weight and tensile forces. Often, expensive tools and expertise are also required, especially with concrete ceilings or ceilings containing cavities. • Visual impairment • A permanently installed pulley system on the ceiling can visually detract from the room, especially in living spaces. It can be perceived as disruptive or out of place when not in use. • Damage to the ceiling • Installation requires drilling holes or inserting fasteners that can damage the ceiling. Later removal of the pulley system will leave holes or other marks that will need to be repaired. • Limited exercise variation • Since the direction of pull only occurs from above, the exercise variation is limited. • Limited suitability for use in rented apartments • In rented properties, installing a ceiling-mounted system can be difficult or even impossible, as many landlords do not allow permanent alterations to the ceilings. This significantly limits the use of such a solution in rented apartments.

[0005] Furthermore, there are known cable-operated devices that are wedged between the door leaf and the door frame when the door is closed. Wedged between the door leaf and the door frame when the door is closed has the following disadvantages: • Inadequate fastening • The pulley may not be securely clamped between the door leaf and the door frame, especially if the pressure varies significantly during training. This could cause the pulley to slip out during training, posing a safety risk. • Severely limited weight capacity • Due to the unstable mounting, very little weight can be used, which reduces the training stimulus. • Damage to the door • Due to the unstable mounting, there is a risk that the door or door frame will be damaged over time by friction. This is especially true if a roller is used for training.

[0006] Finally, wall-mounted lat pulldown stations and cable pulley stations are also available. However, wall-mounted cable pulley stations have the following disadvantages: • Complex installation • Stable wall mounting often requires a complex installation process involving drilling and the use of specialized fasteners, such as heavy-duty anchors. Assembling the bulky components can also be challenging. This can be time-consuming and complicated, especially if the wall structure (e.g., concrete or brick) is not ideal. • Damage to the wall • Wall mounting can leave marks. After installation, holes and damage to the wall may occur, which will need to be repaired if the cable pull station is later removed. • Dependence of the wall structure • Not all walls are suitable for mounting a cable pulley station. Drywall or thin walls may not offer the necessary stability and load-bearing capacity to securely hold the unit, especially under heavy loads. • Limited placement options Wall mounting limits flexibility in where the device can be placed. Once installed, the cable pull station is firmly anchored and cannot be easily moved. This can be problematic if the room's use changes or if multiple people with different needs want to use the room. • Limited suitability for use in rented apartments • In rented properties, it can be difficult or even impossible to mount a cable pulley station on the wall, as many landlords do not allow permanent alterations to the walls. This significantly limits the use of such a solution in rented apartments. • High purchase costs • Wall-mounted cable pull stations are usually expensive. • Takes up space • The station itself, as well as the space required for conducting the exercises, significantly restricts the use of the room. This can be problematic in small rooms or apartments, as it occupies a large area. • Aesthetics in living spaces • A wall-mounted cable management station can negatively impact the aesthetics of a room. Especially in living rooms or stylishly furnished areas, the device can be perceived as disruptive or out of place, as it typically appears large, bulky, and industrial. Even when not in use, the station remains a visible and dominant part of the room.

[0007] The present invention aims to develop and / or further develop a clamping bracket of the type mentioned above in such a way that it enables high mobility, simple and quick assembly and disassembly, and space-saving storage. Furthermore, the clamping bracket should exhibit high stability even under high force in all directions; in particular, longitudinal displacement of a frame leg should be effectively prevented despite simple and quick assembly. Another objective is that the clamping bracket be adaptable to different frame widths. In particular, the invention aims to provide an effective, comfortable, and versatile training device, especially a cable pulley training device, which should enable a new training option for home use.

[0008] The problem is solved according to the invention by the features of at least one of claims 1, 2, 3 and / or 4.

[0009] It is provided that the clamping arms are designed to encompass the frame leg at least partially and that the clamping mechanism is a longitudinal clamping mechanism, wherein the clamping arms can be clamped against the frame leg with a first force, such as longitudinal force, wherein the first force, such as longitudinal force, runs in a plane spanned by the frame or substantially parallel to this plane.

[0010] Alternatively, it is provided that the clamping arms are designed to encompass the frame leg at least section by section and that the clamping mechanism is a transverse clamping mechanism, wherein the clamping arms can be clamped against the frame leg with a second force, such as shear force, wherein the second force, such as shear force, is transverse or substantially transverse to the plane spanned by the frame.

[0011] According to a further preferred alternative, the clamping arms are designed to encompass the frame leg at least section by section, a first clamping mechanism is a longitudinal clamping mechanism, the clamping arms being able to be clamped against the frame leg with a first force, the first force being in a plane spanned by the frame or substantially parallel to that plane, and that a second clamping mechanism is a transverse clamping mechanism, wherein the clamping arms can be clamped against the frame leg by a second force, wherein the second force is transverse or substantially transverse to the plane spanned by the frame.

[0012] It may also be provided that the clamping arms are designed to encompass the frame leg at least section by section, that a first clamping mechanism is a longitudinal clamping mechanism, wherein the clamping arms can be clamped against the frame leg with a first force, wherein the first force lies in a plane spanned by the frame or substantially parallel to this plane, or that a second clamping mechanism is a transverse clamping mechanism, wherein the clamping arms can be clamped against the frame leg with a second force, wherein the second force lies transversely or substantially transversely to the plane spanned by the frame.

[0013] The clamping bracket according to the invention is mobile and enables stable attachment of training equipment to both a horizontal and a vertical frame leg of a frame, such as a door frame, whereby by clamping the clamping arms against the frame leg, displacement, twisting and / or tilting in all directions, in particular in the longitudinal and / or transverse direction, of the frame leg is prevented even under great force, in order to enable safe fitness training.

[0014] According to one embodiment, the clamping fixture can comprise a clamping arm carrier to which at least one of the clamping arms is preferably coupled by force and / or positive locking. Preferably, at least two clamping arms are coupled to the clamping arm carrier by force and / or positive locking.

[0015] The tension arm support can be designed in the form of a rail or a joint.

[0016] The clamping arm support is preferably designed as a component of the longitudinal clamping mechanism and / or the transverse clamping mechanism in order to transmit the first force, such as longitudinal force, in the longitudinal direction and / or the second force, such as transverse force, in the transverse direction to the frame leg and / or the clamping arms.

[0017] A preferred embodiment is characterized in that the clamping arms each have a first leg, wherein the first legs are part of the transverse clamping mechanism and are clamped against the frame leg with force in the operating position and / or are part of the longitudinal clamping mechanism and transmit the longitudinal force in the operating position.

[0018] The first legs can be coupled directly or indirectly to the tension arm support.

[0019] Preferably, the first legs are aligned parallel or substantially parallel to each other and / or transversely or substantially transversely to the clamping arm support.

[0020] Furthermore, it is provided that the clamping arms each have a second leg, wherein the second leg is arranged at an angle, preferably at a right angle, to the first leg, preferably at a first end of the first leg. Preferably, the second legs are aligned within a clamping space defined by the clamping arms or are aligned with each other.

[0021] The design of the clamping arms has the advantage that the clamping arms encompass at least a section of the frame leg, with the first legs preferably being parallel or substantially parallel to an end face of a front or rear frame element of the frame leg, and the second legs preferably being parallel or substantially parallel to a circumferential edge of the front or rear frame element of the frame leg. This creates a large contact surface, which ensures high static friction and thus high stability of the clamping bracket's attachment to the frame leg.

[0022] Furthermore, it is provided that the second legs of the clamping arms are part of the longitudinal clamping mechanism and are clamped against the frame leg by the longitudinal force in the operating position.

[0023] To clamp the clamping bracket to the frame, the longitudinal clamping mechanism is provided to have at least one longitudinal clamping element which is designed to apply the longitudinal force to clamp against the frame leg, preferably clamping the longitudinal clamping element and the second legs against the frame leg.

[0024] The longitudinal clamping element can be coupled to the clamping arm carrier and / or to at least one of the second legs, such as by force-fit and / or form-fit connection.

[0025] The longitudinal clamping element can have a longitudinal pressure element which can be subjected to force against the frame leg, so that preferably the frame leg is clamped in the operating position between the second legs and the longitudinal pressure element.

[0026] The longitudinal pressure element can be coupled to the longitudinal clamping element, preferably by means of a hinge, and preferably aligned or alignable parallel to the second legs of the clamping arms.

[0027] To adapt to different frame thicknesses of the frame leg, at least one of the clamping arms can be arranged to be adjustable relative to each other and / or to the clamping arm support; in particular, at least one of the clamping arms can be positioned in the longitudinal direction along the clamping arm support, preferably continuously adjustable, such as being displaceable.

[0028] Since at least one of the clamping arms is slidably mounted along the clamping arm carrier, it is ensured that the clamping arms can be positioned close to the end face of the frame leg, even with different frame thicknesses. Because the clamping arms lie flat against the end faces in the operating position, the force application points between the clamping arms and the clamping arm carrier are also at their minimum distance, thus enabling optimal force transmission with short lever arms from the clamping arm carrier to the clamping arms.

[0029] Alternatively or in addition to the longitudinal clamping mechanism, the clamping bracket can have a transverse clamping mechanism.

[0030] The transverse clamping mechanism comprises at least one transverse clamping element which is designed to apply the transverse force to clamp against the frame leg, preferably clamping the first leg of the clamping arms with the transverse force against the frame leg.

[0031] Particularly preferably, the transverse clamping mechanism has a counter-holder with which the transverse clamping element is coupled to transmit the transverse force, i.e., connected by force and / or form locking.

[0032] The counter-holder is preferably coupled to the clamping arm support by means of force-fit and / or form-fit for the transmission of the longitudinal and / or transverse force.

[0033] Preferably, the counter-holder is oriented transversely or substantially transversely to the clamping arm carrier and / or preferably parallel or substantially parallel to the first leg of at least one of the clamping arms in order to exert a clamping force in the direction of the clamping arm.

[0034] The transverse clamping element can be subjected to force against at least one of the clamping arms, preferably against the first leg of one of the clamping arms, so that the frame leg is clamped between the first legs in the operating position.

[0035] Furthermore, it may be provided that the transverse clamping mechanism is designed to clamp the frame leg in the operating position with force between the clamping arms, preferably between the first legs of the clamping arms.

[0036] The transverse clamping element can also have a pressure element, which is preferably articulated to the transverse clamping element.

[0037] The transverse clamping element can also have a pressure element which rests against the first leg, preferably in a force-fit manner, and can be clamped.

[0038] An alternative embodiment is characterized in that the transverse clamping element has a pressure element which has a first leg for transmitting longitudinal and transverse forces and a second leg for transmitting longitudinal forces, wherein the pressure element for transmitting the longitudinal and / or transverse forces is coupled to the transverse clamping element, preferably by force and / or form locking, and wherein the transverse clamping element is coupled to the clamping arm carrier via the counter support for transmitting the longitudinal and / or transverse forces.

[0039] To adapt to different frame thicknesses of the frame leg, it is provided that the counter support is arranged to be adjustable relative to the clamping arm support, preferably positionable in the longitudinal direction along the clamping arm support, preferably continuously adjustable, i.e., slidable.

[0040] To ensure optimal force transmission across different frame widths, the clamping arm support and / or the counter support is designed to have one or more openings, such as threads, bores, punched holes and / or a slot, in the longitudinal and / or transverse direction.

[0041] Particularly preferably, the longitudinal clamping element and / or the transverse clamping element is designed as a clamping screw, preferably as a knurled screw.

[0042] A particularly simple and stable design is characterized by the fact that at least one of the openings in the clamping arm carrier is a threaded hole in which the longitudinal clamping element is arranged.

[0043] High flexibility and adaptation to different frame geometries is achieved by having at least one of the openings of the clamping arm carrier be an elongated hole, in which a sliding nut for receiving the longitudinal clamping element, preferably in the form of a clamping screw, is preferably arranged in the elongated hole.

[0044] The clamping screw can therefore be continuously positioned in various locations along the longitudinal axis of the clamping arm support, so that the force can be applied to the inner surface of the frame leg, preferably in the center. For very wide frame legs, several clamping elements can also be used.

[0045] The clamping arm support is preferably made of a flat or profiled material, preferably in the form of a metal element such as a sheet metal strip or profile rail. The flat material forms a mounting surface for arranging holding elements for objects, such as training equipment, in various positions.

[0046] To reduce deflection of the clamping arm support when subjected to force from the longitudinal clamping element and / or the weight, the clamping arm support can be provided with at least one reinforcing element, such as a reinforcing rib, preferably in the longitudinal and / or transverse direction. In particular, the clamping arm support can be designed as a metal element, such as sheet metal or corrugated sheet, with reinforcing ribs.

[0047] The longitudinal clamping element, such as a clamping screw, can also be arranged in various positions both longitudinally and transversely of the clamping arm support to enable optimal force application when mounted on a horizontal or vertical frame leg. In particular, when mounted on a vertical frame leg, the longitudinal clamping element, such as a clamping screw, can be arranged transversely upwards, i.e., offset off-center, to dissipate tensile forces acting in the vertical direction and to prevent the clamping bracket from tilting.

[0048] Alternatively, it is possible not to clamp the longitudinal clamping element firmly against the frame leg, i.e., to deliberately allow tilting in the longitudinal direction of the frame leg, thereby enabling the clamping bracket to be fastened by wedging and / or tilting.

[0049] High stability and a secure hold are also achieved by making the first and second legs of the clamping arms from a flat or profiled material, preferably in the form of a metal element such as sheet metal strips. The flat material forms a contact surface by means of which the first and second legs rest against the end faces and surrounding edges of the frame and are clamped.

[0050] To prevent damage to the frame and / or to achieve additional stability during clamping, making displacement even more difficult, the contact surfaces with the frame, in particular the first and / or second legs of the clamping arms and / or the pressure elements of the longitudinal or transverse clamping mechanism, may have protective, spacer or anti-slip elements, such as rubber elements.

[0051] To enable the clamping bracket to be mounted on frame legs of different sizes and shapes, the first leg of the clamping arms can have a length ranging from 1 cm to 25 cm, preferably 4 cm to 16 cm, and particularly preferably 8 cm to 12 cm, and / or a width ranging from 0.1 cm to 25 cm, preferably 4 cm to 20 cm, and particularly preferably 8 cm to 16 cm. The clamping arms, preferably the first and / or second leg, can also be designed to be variable in length, such as telescopic. This can be achieved, in particular, by dividing the leg into two parts, each with an elongated hole, and by using a clamping screw with a nut to fix the desired length.

[0052] The width of the second leg, i.e., the extension in the longitudinal direction of the frame leg, is of particular importance for the tilting resistance, wherein it is provided that the second leg of the clamping arms has a length in the range of 0.1 cm to 10 cm, preferably 0.5 cm to 5 cm, particularly preferably 1 cm to 2 cm and a width in the range of 0.1 cm to 25 cm, preferably 4 cm to 20 cm, particularly preferably 8 cm to 16 cm.

[0053] To provide sufficient mounting surface and strength, the flat or profile material of the clamping arm support is designed to have a diameter of 0.1 cm to 25 cm, preferably 4 cm to 20 cm, and particularly preferably 8 cm to 16 cm, and a length of 5 cm to 50 cm, preferably 7 cm to 40 cm, and particularly preferably 9 cm to 30 cm.

[0054] Preferably, the first clamping arm with the clamping arm support is designed as a one-piece base element, preferably a C-shaped element, in particular in the form of a C-shaped metal element, such as sheet metal strips or flat rails.

[0055] Particularly preferably, at least one of the clamping arms, preferably the second clamping arm, has a recess adapted to the cross-section of the clamping arm carrier for coupling, preferably by positive locking, with the clamping arm carrier, which is designed to allow at least one of the clamping arms, preferably the second clamping arm, to be moved in the longitudinal direction of the clamping arm carrier.

[0056] Furthermore, it may be provided that the recess is formed in an end on the tension arm support side of the first leg of the tension arm.

[0057] This allows the clamping arm to be slid onto the clamping arm support and moved longitudinally so that the clamping arms, with their contact surfaces, lie flat against the end faces of the frame leg. The recess or opening is designed to be formed in the clamping arm support end of the first leg of the clamping arm. The combination of the C-shaped base element with the slide-on second clamping arm enables simple assembly by just one person with few components.

[0058] This ensures that the clamping arms with their contact surfaces can always lie flat against the end faces of the frame, while the counter-holder can be brought into the optimal position to optimize the force exerted by the transverse clamping element on the second clamping arm.

[0059] Particularly preferred is at least one of the clamping arms, preferably the second clamping arm, designed in an L-shape, in particular in the form of an L-shaped angle element, comprising the first leg and the second leg.

[0060] Preferably, the first leg of one of the clamping arms, preferably that of the second clamping arm, has a recess adapted to the cross-section of the clamping arm carrier, preferably in the form of a slot-shaped cutout, by means of which the second clamping arm is preferably positively coupled to the clamping arm carrier and is displaceable in the longitudinal direction along it.

[0061] It has proven particularly advantageous if the counterholder is I-shaped, especially in the form of a plate-shaped element, such as a metal element, especially a sheet metal strip, wherein the opening, such as a thread or elongated hole, for the transverse clamping element is preferably formed in an upper area of ​​the counterholder.

[0062] Preferably, the counter-holder has a recess adapted to the cross-section of the clamping arm carrier, such as a slot-shaped cutout, by means of which the counter-holder can be adjusted or moved along the clamping arm carrier to a desired position, preferably steplessly.

[0063] The recess can be formed in an end of the counterholder on the tension arm side.

[0064] The recess is preferably adapted to the cross-section of the clamping arm support in such a way that, when force is applied to the transverse clamping element against the frame leg or one of the clamping arms, the counter-support is anchored or tilted in its position on the clamping arm support. The counter-support has a slightly larger cutout relative to the material thickness and width of the clamping arm support, allowing the counter-support to tilt slightly and thus tilt onto the clamping arm support.

[0065] Preferably, the recess or opening in the first leg of the first or second clamping arm is oriented longitudinally such that the length of the first leg of the first or second clamping arm extending between the recess and the second leg corresponds to the length of the leg of the other clamping arm. This ensures that the clamping arm support inserted into the recess or opening is horizontal or substantially horizontal in its operating position.

[0066] The counterholder can also be L-shaped, in particular in the form of an L-shaped angle element, such as a metal angle, especially a sheet metal angle, with a first leg that runs parallel or substantially parallel to one of the clamping arms, in which the opening, such as a thread or elongated hole, for the transverse clamping element is preferably formed, and with a second leg that is angled, preferably perpendicular, to the first leg and can be clamped against the clamping arm support by means of a third clamping element, such as a clamping screw, preferably by force and / or form locking.

[0067] Alternatively, the second clamping arm can be U- or Z-shaped, in particular in the form of a U- or Z-shaped element, such as metal elements, especially sheet metal strips, comprising the first leg and the second leg.

[0068] Preferably, the first leg has a recess adapted to the cross-section of the clamping arm carrier, into which the clamping arm carrier engages, so that the second clamping arm is preferably coupled to the clamping arm carrier by force and / or form locking and is preferably infinitely displaceable in the longitudinal direction along it.

[0069] The U- or Z-shaped clamping arm can also have a third leg that runs parallel to the second leg and that an opening, such as a bore, is arranged in the third leg to accommodate a fourth clamping element, such as a clamping screw, by means of which the third leg can be clamped against the clamping arm support with force.

[0070] According to one embodiment, a spacer element, such as a spacer sleeve, is arranged between the third leg and the clamping arm support. This spacer has a height corresponding to the distance between the lower edge of the clamping arm support and the upper edge of the third leg. This allows the clamping arm to be fixed in position steplessly without exerting any force on the frame leg.

[0071] According to a second embodiment, a gap, i.e., no spacer element, is arranged between the third leg and the tension arm support. Thus, the third leg can be clamped against the tension arm support using the fourth clamping element, so that the first leg is subjected to force against the frame leg.

[0072] The clamping screw is preferably designed as a knurled screw, at the front end of which the pressure element, preferably a rubberized pressure plate, is arranged. The knurled screw is easy to handle and provides sufficient clamping force.

[0073] For attaching training equipment such as pulleys, resistance bands, suspension trainers, or calisthenics equipment, the clamping bracket, in particular the first clamping arm and / or the second clamping arm and / or the clamping arm support, is provided with a fastening element such as a pulley holder or eyelet. The fastening element is preferably arranged centrally in the longitudinal and / or transverse direction of the first clamping arm, the second clamping arm, and / or the clamping arm support.

[0074] The clamping bracket is particularly preferred as a bracket for a horizontal and / or vertical frame leg.

[0075] The tensioning bracket can be a cable pulley bracket, wherein preferably the fastening element can be a first pulley holder for a cable pulley, which is preferably directly connected to the tensioning arm support and / or the first and / or second tensioning arm.

[0076] Alternatively, particularly when the clamping bracket is attached to a vertical frame leg, the clamping bracket can be a cable pulley bracket, wherein preferably the fastening element can be a second pulley holder for the cable pulley arranged on a support arm extending from the clamping arm support and / or first clamping arm and / or second clamping arm, which forms a mounting platform.

[0077] Furthermore, the at least one clamping bracket, which is arranged on a vertical frame leg of the frame, can have a support arm, which is preferably arranged on the clamping arm support and / or first clamping arm and / or second clamping arm, which is designed to span a mounting surface for the items in the form of training equipment, which is preferably located in a plane spanned by the clamping arms or is arranged horizontally or substantially horizontally or at an angle to it.

[0078] The frame can be a door frame, preferably comprising a horizontal frame leg and at least one vertical frame leg, wherein the frame legs have a front frame element, such as rebate cladding, with at least one first end face and at least one first circumferential edge surface, a rear frame element, such as decorative cladding, with at least one second end face and at least one second circumferential edge surface, and an inner frame element, such as lining bed, with at least one inner surface.

[0079] Preferably, the first legs, the second legs and the longitudinal pressure element of the longitudinal clamping element form a clamping space encompassing the frame leg at least partially, wherein the first legs of the clamping arms in the operating position each bear against the first or second end face of the frame leg at least partially, wherein the second legs of the clamping arms each bear against the first or second circumferential edge surface at least partially, and wherein the longitudinal pressure element of the longitudinal clamping element bears against the inner surface at least partially.

[0080] Regarding the attachment of the clamping bracket to the vertical and / or horizontal frame leg, it should be noted that the longitudinal clamping element and / or the transverse clamping element can also be a wedge by means of which the clamping arms can be clamped against the frame leg.

[0081] Alternatively, and in an inventive manner, the clamping bracket for the vertical frame leg can have a further clamping element which is arranged between the support arm and a floor surface, by means of which the clamping bracket can be subjected to a force directed in the longitudinal direction of the frame leg in order to tilt or wedge the clamping bracket against the frame leg.

[0082] Furthermore, it is provided that the clamping arm support is designed to be variable in length, in particular telescopic.

[0083] Furthermore, it is provided that the counter-holder has a length in the range of 1 cm to 25 cm, preferably 4 cm to 16 cm, particularly preferably 8 cm to 12 cm and / or a width in the range of 0.1 cm to 25 cm, preferably 4 cm to 20 cm, particularly preferably 8 cm to 16 cm.

[0084] Furthermore, it is provided that the material, in particular the flat material or profile material, of the clamping arms, the clamping arm support and / or the counter support, is a metal, preferably steel or steel alloy, or contains such material.

[0085] Furthermore, it can be provided that the material preferably has a thickness in the range of 0.5 mm to 8 mm, preferably 2 mm to 5 mm.

[0086] Furthermore, it may be provided that the longitudinal clamping element, such as a clamping screw, is arranged offset in the transverse direction of the clamping arm support when the clamping bracket is mounted on a vertical frame leg, i.e., off-center, in order to dissipate force components acting in the plane of the frame, in particular force components in the direction of the horizontal frame leg, i.e., upwards.

[0087] The tensioning device described above can be used particularly preferably in a training facility, in particular a fitness facility for training human muscles, with a frame, such as a door frame, and at least one tensioning device, preferably according to at least one of the preceding claims, for detachably attaching objects, in particular training equipment, such as a pulley, resistance band, sling trainer or calisthenics equipment, to a frame leg of the frame, such as a door frame.

[0089] It may be provided that at least a first clamping bracket is attached to a horizontal frame leg of the frame and / or at least a second clamping bracket is attached to at least one vertical frame leg of the frame.

[0090] Furthermore, it can be provided that at least one of the clamping brackets comprises at least one clamping mechanism with at least two clamping arms, wherein at least one of the clamping arms can be clamped with force against the frame leg to secure the clamping bracket, wherein the clamping arms are designed to encompass the frame leg at least section by section, and wherein a first clamping mechanism is a longitudinal clamping mechanism, wherein the clamping arms can be clamped with a first force against the frame leg, wherein the first force is in a plane spanned by the frame or substantially parallel to this plane, and / or wherein a second clamping mechanism is a transverse clamping mechanism, wherein the clamping arms can be clamped with a second force against the frame leg, wherein the second force is transverse or substantially transverse to the plane spanned by the frame.

[0122] Further details, advantages and features of the invention will become apparent not only from the claims, the features to be derived therefrom - individually and / or in combination - but also from the following description of embodiments shown in the figures.

[0123] They show: Fig. 1 a perspective view of a door frame with clamping brackets according to the invention for attaching pulleys to a horizontal and a vertical frame leg to form a training device, Fig. 2 a perspective view of a first embodiment of a clamping bracket for attaching a pulley to a horizontal frame leg, Fig. 3 a perspective view of the first embodiment of a clamping bracket with a support element for attaching a pulley to a vertical frame leg, Fig. 4 a perspective view of a second embodiment of a clamping bracket, preferably for attaching a cable pulley to a horizontal or vertical frame leg, Fig. 5 a perspective view of a third embodiment of a clamping bracket for attaching a pulley to a horizontal frame leg, Fig. 6 a perspective view of the third embodiment of a clamping bracket in top view for attaching a pulley to a vertical frame leg, Fig. 7 a perspective view of the third embodiment of a clamping bracket in bottom view for attaching a pulley to a vertical frame leg, Fig. 8 a perspective view of a fourth embodiment of a clamping bracket for attaching a pulley to a horizontal frame leg and Fig. 9 a perspective view of the fourth embodiment of a tensioning bracket in top view for attaching a pulley to a vertical frame leg.

[0124] Fig. Figure 1 shows a frame 10, such as a door frame or door jamb, with a first pulley 12, which is stably attached to a horizontal frame leg 16 of the frame 10 by means of a first tensioning bracket 14 according to the invention. Furthermore, a second pulley 18 is attached to a vertical frame leg 22 of the frame 10 by means of a second tensioning bracket 20 according to the invention. In principle, several tensioning brackets can be attached to the frame 10 to enable even more versatile fitness training with a wider range of exercises. For this purpose, the tensioning bracket 14, which is attached to the horizontal frame leg 16, forms a base, so that there is sufficient height to a floor surface 24 to allow a weight 26 to be moved with a cable 28 over the pulley 12 with sufficient travel and to ensure proper exercise execution.In principle, multiple tension brackets with several and / or independent cables can be attached to frame 10 to enable even more versatile fitness training with a wider range of exercises. The weight 26 can be adjusted in increments of typical weight plates.

[0125] The upper clamping bracket 14 can be arranged in any position along the horizontal frame leg 16, in particular recessed in the middle to avoid collision with the lower clamping bracket 20. The cable pulleys 12, 18 are received in fastening elements 30, 32, which enable automatic angular alignment (not shown) depending on the position of the clamping brackets. Preferably, the fastening elements 30, 32 are pivotally mounted, in particular rotatably and / or tiltably.

[0126] In the illustrated embodiment, the cable 28 is guided over the lower pulley 18, which is attached to the vertical frame leg 22, and deflected in such a way that exercises such as bicep curls or rows can be performed while sitting, standing, and / or lying down. For this purpose, a retaining element, such as a carabiner, is arranged at the end of the cable for attaching a handle 34, such as grips or a triceps rope (not shown). To prevent the cable 28 from being pulled back by the weight 26 when the cable is not in use, a retaining element 36, such as a ball, is arranged at the end of the cable 28.

[0127] Fig. Figure 2 shows a perspective view of a first embodiment of a tensioning bracket 38 for detachably attaching a cable pulley 40 to the horizontal frame leg 16 of the frame 10 spanning an opening, such as a door frame. The tensioning bracket 38 comprises a first tensioning arm 42, a second tensioning arm 44, and a tensioning arm support 46.

[0128] The clamping arms 42, 44 each have a first leg 48, 50, wherein the first legs 48, 50 are positively coupled to the clamping arm carrier 46 and are aligned transversely to it.

[0129] Furthermore, the clamping arms 42, 44 each have a second leg 52, 54, wherein the second legs 52, 54 are aligned with each other and in the longitudinal direction of the clamping arm support 46. The second legs 52, 54 are arranged at a first end of the first leg at an angle, preferably at a right angle, to the first leg and are aligned in a clamping space opened up by the clamping arms.

[0130] The second clamping arm 54 is arranged to be displaceable along the clamping arm support 46 in its longitudinal direction to adapt to different frame thicknesses of the frame leg, so that the first legs 48, 50 can each be placed against a front and rear end face 56, 58 of the frame 10, e.g., end faces of a rebate trim or decorative trim of a door frame, and the second legs 52, 54 can each be placed against a circumferential edge surface 60, 62 of the frame 10, e.g., circumferential edge surface of the rebate trim or decorative trim of a door frame, as shown in Fig. 1 shown.

[0131] According to one aspect of the invention, the clamping bracket 38 has a longitudinal clamping mechanism comprising the clamping arms 42, 44, the clamping arm support 46, and the longitudinal clamping element 64. By means of the longitudinal clamping element 64, the clamping arms 42, 44 can be clamped against the frame leg with a first force LK, wherein the first force LK extends in a plane spanned by the frame or substantially parallel to this plane. The longitudinal clamping element 64 is coupled to the clamping arm support 46 by force-fit and / or positive-fit, so that the second legs 52, 54 can each be clamped against the circumferential edge surface 60, 62 of the frame leg, and the longitudinal clamping element 64 can be clamped from the clamping arm support 46 against an inner surface 66 of the frame leg, such as the lining of a door frame.

[0132] According to a further aspect of the invention, the clamping bracket 38 has a transverse clamping mechanism comprising the clamping arms 42, 44, the clamping arm support 46, a transverse clamping element 68, and a counter support 69. The transverse clamping element 68 is coupled to the counter support 69 by means of a force-fit and / or positive-locking connection for transmitting the second force QK, i.e., transverse force. By means of the transverse clamping element 68, the clamping arms 42, 44 can be clamped against the frame leg with the second force QK, the second force QK acting transversely to the plane spanned by the frame. The transverse clamping mechanism includes the transverse clamping element 68, by means of which the first legs 48, 50 can each be clamped against the end faces 56, 58 of the frame leg.

[0133] The clamping arm support 46 has several threads or bores 70, 72, 74, 76 and / or an elongated hole 78 in the longitudinal and transverse directions for receiving the longitudinal clamping element 64 in the form of a clamping screw 80, such as a knurled screw, with a longitudinal pressure element 82, preferably in the form of a rubberized pressure plate. The clamping screw 80 is coupled to the clamping arm support 46 by force-fit and / or positive-fit and can be clamped transversely to the clamping arm support 46 against the inner surface 66 of the frame leg, so that the second legs 52, 54 are clamped against the circumferential edge surfaces 60, 62.

[0134] A sliding nut 84 for receiving the clamping screw 80 is arranged in the elongated hole 78, so that force transmission takes place when the clamping screw 80 is tightened.

[0135] The clamping arm support 46 is made of a flat or profile material, preferably in the form of a metal element, such as sheet metal strips or profile rails.

[0136] The first and second legs 48, 50, 52, 54 of the clamping arms 42, 44 are made of a flat or profiled material, preferably in the form of a metal element, such as sheet metal strips. This ensures a sufficiently large contact surface on both the end faces 56, 58 and the circumferential edge faces 60, 62 of the frame shackle 16, 22.

[0137] In the illustrated embodiment, the first clamping arm 42 and the clamping arm support 46 are designed as a one-piece, preferably C-shaped base element 86, in particular in the form of a C-shaped metal element, such as sheet metal strips, which also forms the basis for the embodiments described below.

[0138] The second clamping arm 44 has a recess or opening 88 corresponding to a cross-section of the flat material of the clamping arm carrier 46 for positive locking connection with the clamping arm carrier 46 and can be pushed onto the clamping arm carrier 46 and moved in the longitudinal direction.

[0139] In the illustrated embodiment, the second clamping arm 44 is L-shaped, in particular in the form of an L-shaped sheet metal strip, comprising the first leg 50 and the second leg 54, wherein the first leg 50 has the slot-shaped recess or opening 88, by means of which the second clamping arm 44 is positively coupled to the clamping arm carrier 46 and is displaceable in the longitudinal direction along it.

[0140] The transverse clamping element 68 is coupled to the counter support 69 by force and / or form locking, wherein the counter support 69 can be coupled to the clamping arm carrier 46 by force and / or form locking and is displaceable in the longitudinal direction, and wherein an upper section 92 of the counter support 69 runs parallel or substantially parallel to the second clamping arm 44, so that the transverse clamping element 68 can be clamped against the second clamping arm 44 with force QK starting from the counter support 69.

[0141] The transverse clamping element 68 is a clamping screw 96 with transverse pressure element 98, which is received in a thread 94 formed in the counterholder or in a nut (not shown) that interacts with the counterholder in a force-locking and / or form-locking manner.

[0142] Alternatively, a slot can be formed in the longitudinal direction of the counterholder 69 (not shown), in which the clamping screw 96 is arranged to be displaceable in the longitudinal direction, wherein preferably a nut is arranged in the slot as a sliding nut (not shown) to receive the clamping screw 96.

[0143] In the illustrated embodiment, the counterholder 69 is I-shaped, in particular in the form of an I-shaped sheet metal strip, wherein the thread 94 or alternatively an elongated hole (not shown) for the clamping screw 96 with pressure element 98 is provided in the upper section 92 of the counterholder 69.

[0144] In an end 100 on the side of the clamping arm support, a recess or opening 102 corresponding to the cross-section of the clamping arm support 46 is formed in the form of a slot, by means of which the counter support 69 can be moved along the clamping arm support 46 into a desired position and wherein the recess or opening 102 is adapted to the cross-section of the clamping arm support 46 in such a way that the counter support 69 is anchored or wedged in its position when force is applied by means of the clamping screw 96 against the second clamping arm 44 on the clamping arm support 46.

[0145] In the illustrated embodiment, the first clamping arm 42 has a fastening element 104 in the form of an eyelet for receiving further training equipment, such as resistance band, sling trainer or calisthenics equipment.

[0146] The tension arm support 46 forms a mounting platform to which a further fastening element 106, in the form of a roller holder for the cable pulley 40, can be mounted, for example, by screwing it in place. The roller holder can be articulated or arranged in a pivotal manner so that the cable pulley 40 can rotate and / or tilt in different directions. The fastening element 106 is secured with a screw in the bore 70, which is located longitudinally in the center of the tension arm support 46.

[0147] The first legs 48, 50 of the clamping arms 42, 44 preferably have a length in the range of 1 cm to 25 cm, preferably 10 cm, so that they can be adapted to different dimensions of frame legs. The legs preferably have a width in the range of 0.1 cm to 25 cm, preferably 12 cm, so that they extend to the necessary extent in the longitudinal direction of the frame legs to generate sufficient static friction during clamping.

[0148] The second legs 52, 54 of the clamping arms 42, 44 preferably have a length in the range of 0.1 cm to 10 cm, preferably 1.5 cm and a width in the range of 0.1 cm to 25 cm, preferably 12 cm, so that they extend to the required extent in the longitudinal direction of the frame legs in order to generate sufficient static friction when clamping.

[0149] The flat or profile material of the clamping arm support 46 has a width in the range of 0.1 cm to 25 cm, preferably 12 cm, and a length in the range of 5 cm to 50 cm, preferably 28 cm.

[0150] The first and second legs 48, 50, 52, 54 of the clamping arms 42, 44 have contact surfaces on the inside for contacting the frame, wherein protective, spacer or anti-slip elements, such as rubber elements, are preferably arranged permanently or detachably on the contact surfaces, such as by being attached, glued or screwed on (not shown).

[0151] Fig. Figure 3 shows a perspective view of the first embodiment of the clamping bracket 38, with C-shaped base element 86, L-shaped second clamping element 44 and I-shaped counter-holder 69, the structure and function of which are shown in the embodiment according to Fig. 2 corresponds.

[0152] To attach a cable pulley 108 to the vertical frame leg 22 of the frame 10, a support element 110 in the form of an L-shaped support, such as a reinforced angle bracket, is provided, with a short leg 112 that can be connected to the tension arm support 46, e.g., by screwing it on, and a long leg 114 that forms a mounting surface with openings, such as threaded holes 116 or bores 118, on which a pulley holder 120 for the cable pulley 108 can be mounted. The pulley holder 120 is articulated or articulated so that the cable pulley can be automatically aligned in different directions, preferably rotated and / or tilted.

[0153] Fig. Figure 4 shows a perspective view of a second embodiment of a clamping bracket 122 for attaching a cable pulley to the horizontal or vertical frame leg 16, 22. The clamping bracket 122 comprises the C-shaped base element 86 and the L-shaped second clamping arm 44, the structure and function of which are described in the embodiment shown. Fig. 2 corresponds.

[0154] In contrast to the clamping bracket 38, the clamping bracket 122 has a counter-holder 124 which is L-shaped, in particular in the form of an L-shaped angle, such as sheet metal angles.

[0155] The counter-holder 124 comprises a first leg 126, which runs parallel or substantially parallel to the second clamping arm 44. A thread 128 or an elongated hole (not shown) for the clamping screw 68 is formed in the leg 126.

[0156] Furthermore, the counter-holder 124 comprises a second leg 130, which extends at right angles or substantially at right angles to the first leg 126 and can be clamped to the clamping arm support 46 by means of a clamping element 132 in the form of a clamping screw 134, the clamping screw engaging in an opening, such as a threaded bore 136 or a hole, in the second leg 130. The second leg 130 rests on the clamping arm support 46 and can be continuously moved into an optimal position for clamping against the second clamping arm 44. To secure the counter-holder 124 against rotation, the clamping arm support 46 and / or the counter-holder 124 can have guide elements, such as guide rails (not shown).

[0157] As previously described, the tension arm support 46 serves as a mounting surface for the direct attachment of the roller bracket 106 for the cable pulley 40 in a horizontal orientation or for the attachment of the support element 114, on which the roller bracket 120 for the cable pulley 40 can be mounted in a vertical orientation.

[0158] Fig. Figure 5 shows a perspective view of the clamping bracket 14 according to Fig. 1 as a third embodiment for attaching the cable pulley 12 to the horizontal frame leg 16. The clamping bracket 14 comprises the C-shaped base element 86 and the L-shaped counter-holder 124 with transverse clamping element 68, the construction and function of which are described in the embodiment according to Fig. 4 corresponds to.

[0159] The clamping bracket 14 essentially corresponds to the clamping bracket 122 according to Fig. 4, wherein a second clamping arm 140 is Z-shaped, in particular in the form of a Z-shaped sheet metal strip, comprising the first leg 142 and the second leg 144, wherein the first leg 142 has an opening 146, such as a slot, adapted to the cross-section of the first counter-holder 46, by means of which the clamping arm 140 is positively coupled to the first counter-holder 46 and is infinitely displaceable in the longitudinal direction along it.

[0160] Furthermore, the clamping arm 140 has a third leg 148, which runs parallel to the second leg 144 in the opposite direction. The third leg is formed below the opening 146 and has an opening, such as bore 150. A spacer element, such as sleeve 152, is arranged between the third leg 148 and the underside of the clamping arm support 46. A clamping screw 154 passes through the opening, such as bore 150, the spacer element, such as sleeve 152, and the elongated hole 78, and engages in a nut 156 to fix the clamping arm 140.

[0161] The Fig. 6 and Fig. Figure 7 shows a perspective view of the clamping bracket 20. Fig. 1 in top and bottom view for attaching the cable pulley 18 to the vertical frame leg 22 for receiving the cable pull 28.

[0162] To attach the cable pulley 18 to the vertical frame leg 22 of the frame 10, a support element 158 ​​in the form of an L-shaped support, such as a reinforced angle bracket, extends from the tension arm support 46. The angle bracket 158 ​​has a short leg 160, which can be connected to the tension arm support 46, such as by screwing, and a long leg 162, which forms a mounting surface with openings, such as threaded holes 164 or bores 166, on which the pulley holder 32 for the cable pulley 18 can be mounted. The pulley holder 32 is designed to be articulated, such as rotatable and / or tiltable, or is mounted in such a way as to be articulated, such as rotatable and / or tiltable, so that the cable pulley 18 can be automatically aligned in different directions.

[0163] In this design, the clamping screw 64 is received in the thread 72, which is formed off-center in the vertical direction above the elongated hole 78 in order to better prevent the clamping bracket from tilting upwards, i.e. in the direction of the upper cable pulley, under a tensile force with a vertical force component.

[0164] For further stabilization, a reinforcing element 170 is arranged on one underside of the angle piece 158.

[0165] Fig. Figure 8 shows a perspective view of a clamping bracket 172 as a fourth embodiment for attaching the cable pulley 12 preferably to the horizontal frame leg 16.

[0166] The clamping bracket 172 essentially corresponds to the clamping bracket 14 according to Fig. 5, with the difference that the L-shaped counter-support 124 is omitted. The Z-shaped clamping arm 140 is moved along the clamping arm support 46 in the direction of the first clamping arm 42 until the clamping arms 140, 42 abut the end faces 56, 58 of the frame leg 16. In this embodiment, clamping is achieved solely with the clamping screw 64, whereby the second legs 52, 144 are clamped against the circumferential edge 60, 62 of the frame. This embodiment is preferably designed for use on the horizontal frame leg 16, since forces predominantly act in the vertical direction, i.e., transversely to the horizontal frame leg 16.

[0167] Fig. Figure 9 shows a perspective view of a tensioning bracket 176, wherein, for attaching the cable pulley 18 to the vertical frame leg 22 of the frame 10, the support element 158 ​​extends from the tensioning arm support 46 in the form of an L-shaped support, such as a reinforced angle bracket. The angle bracket 158 ​​has a short leg 160, which can be connected to the tensioning arm support 46, such as by screwing, and a long leg 162, which forms a mounting surface with openings, such as threaded holes 164 or bores 166, on which the pulley holder 32 for the cable pulley 18 can be mounted. The pulley holder 32 is, in particular, designed to be articulated, such as rotatable and / or tiltable, or mounted in an articulated manner, such as rotatable and / or tiltable, so that the cable pulley 18 can be automatically aligned in different directions.

[0168] In this version as well, the clamping screw 64 is received in the thread 72, which is formed off-center in the vertical direction above the elongated hole 78 in order to provide optimal support against tilting of the clamping bracket upwards, i.e. in the direction of the upper cable pulley, under a tensile force with a vertical force component.

[0169] In summary, it should be noted that the clamping bracket 14, 20, 38, 39, 122, 172, 176 according to the invention enables a stable fastening of the cable pulley 12, 18 to both a horizontal and a vertical leg of the frame 10, such as a door frame, whereby displacement is prevented even by greater forces by the clamping elements 64, 68 in such a way that safe fitness training is possible.

[0170] The longitudinal clamping element 64 allows the clamping bracket 20, 176 to be clamped against an inner surface of the frame. The longitudinal clamping element 64 is received in a threaded hole 72, which is located vertically above the elongated hole 78, as shown in Fig. Figures 6 to 8 are shown. This ensures that when the tensioning bracket 20, 176 is attached laterally to a door frame 16, it counteracts the upward pulling force exerted by the pulley 18 because the weight is pulled upwards over the pulley 18, preventing the tensioning bracket 20, 176 from tipping upwards.

[0171] In addition, the preferably I-shaped counterholder 69 or the L-shaped counterholder 124 also allows for lateral tightening, since the preferably I-shaped counterholder 69 or the L-shaped counterholder 124 is fixed to the clamping arm carrier 46 by means of a screw and a nut (not shown).

[0172] To ensure that the clamping bracket 14 is horizontally aligned when resting on the door frame, the opening in the form of the cutout 88 of the clamping arm 44 or the cutout 146 of the Z-plate 140 must be precisely aligned with the clamping arm support 46. Horizontal alignment significantly improves stability.

[0173] Stepless adjustment to accommodate different door frame widths is achieved by the elongated hole 78 in the clamping arm carrier 46. This allows the L-shaped counter-holder 124 or the U- or Z-shaped clamping arm to be attached to the clamping arm carrier 46, for example, with a screw and nut (not shown). This is important because otherwise, pressing the clamping arm 44 or the U- or Z-shaped clamping arm 140 against the end face of the door frame would require a knurled screw that is far too long. This would not only be unwieldy but, more importantly, would compromise stability if different door frame widths were to be accommodated simultaneously.

[0174] To ensure sufficient stability when the clamping bracket 14, 20, 38, 39, 122, 172, 176 rests on the door frame 16, 22, the angled projections or legs 52, 54, 144 of the clamping arms 42, 44, 140, which are placed on the edge of the door frame, have a sufficient width so that the overall construction has a sufficient bearing surface and, on the one hand, does not tip over and, on the other hand, has a higher weight distribution over the width of the legs 52, 54, 144, which makes the construction more resistant and allows it to withstand more weight.

[0175] In order to offer the greatest possible stability and weight distribution, it is provided that the cutout 58 of the clamping arm 44 or the cutout 146 of the clamping arm 140 in the form of the Z-shaped sheet metal has the largest possible contact area with the clamping arm carrier.

[0176] To cover different door frame fronts, it is provided that the first tension arm 42 and the second tension arm 44, 140 have a sufficient length so that various typical door frame fronts can be served.

[0177] Preferably, anti-slip rubbers (not shown) are attached to the contact surfaces with the door frame to prevent damage to the door frame and to provide additional stability through the anti-slip properties of the rubber when the overall construction is tightened horizontally and / or vertically.

[0178] The clamping arm support 46 incorporates a variety of different holes and bores. The selection of these holes, bores, and the slot is optimized due to the limited space available for accommodating and securing the necessary components. The holes and bores are designed to ensure that all components can be easily assembled, disassembled, and used.

[0179] For example, the knurled screw with pressure piece for vertical tightening has enough space so that it can be turned by hand without the pulley or tension arm interfering with comfortable rotation of the knurled screw with pressure piece.

[0180] The cable pulleys 12, 18 can be mounted in a pivotable and tiltable manner, so that the cable pulleys 12, 18 can align themselves with each other, thereby ensuring smooth running of the cable pull. QUOTES INCLUDED IN THE DESCRIPTION
