Description

[0001] The invention relates to a push-up handle, comprising at least: a support plate for placing the push-up handle on a surface, a handle unit for supporting a user on the push-up handle, wherein the handle unit is movably mounted relative to the support plate so that, on the one hand, a rotational movement about an axis of rotation is possible and, on the other hand, the axis of rotation is freely movable about a pivot point within a predetermined spatial angle, a ball joint which is connected on one side to the support plate and on the other side to the handle unit, wherein the ball joint defines the spatial angle in which the free movement of the handle unit is possible, a rolling bearing which enables the rotational movement of the handle unit, wherein the axis of rotation of the handle unit passes through the longitudinal axis of the ball joint and the pivot point of the ball joint, and at least one spring which holds the handle unit in a neutral starting position.Furthermore, the invention relates to a training system for this purpose.

[0002] Handles for push-ups and other strength exercises such as handstands, arm balances, dips or the like are already known in various designs from the prior art.

[0003] In a simple embodiment, these are designed as a handle that is positioned on the floor by means of a stand, so that the user does not support himself with the flat of his hand on the floor, but rather grasps the handle.

[0004] Such push-up handles with grip bars are also available in movable designs, where the grip bar can be tilted sideways, for example, see document US 2016 / 0158597 A1, or rotated around a vertical pivot axis, see document DE 21 2007 000 010 U1.

[0005] Other embodiments of movable push-up handles allow both rotational movement and free movement of the handle within a spatial angle, with these push-up handles being designed as a rod-shaped handle arranged in a type of ball socket of a ball joint, see, for example, US 7,585,262 B1, CN 206660485 U or US 10,946,241 B2. A disadvantage of these push-up handles is that both uncontrolled tipping and uncontrolled movement on the floor are possible; for example, the handles can tip over or slide freely to the side, which poses a risk of injury to the user.

[0006] As a further example of state of the art, reference is made to publication US 2014 / 0329651 A1, which also reveals a push-up handle in which both rotation and tilting of the handle are possible.

[0007] To prevent this uncontrolled movement, the push-up handle design described in US Patent 9,789,359 B2, for example, features an additional recess in which the handlebar is positioned. This recess is, in turn, placed in a holder with a flat bottom for secure footing on the floor. This ensures at least a secure footing, preventing lateral slippage. However, a disadvantage of this push-up handle is that, with maximum lateral deflection, the handlebar can tip uncontrollably out of the recess. Furthermore, the handlebar is not connected to the holder within the recess, which further facilitates the handlebar tipping out of the holder.

[0008] As an alternative handle shape to the usual handle bar, a spherical handle is known from the publication US 9 457 227 B2, which can be slightly raised by means of feet and fixedly positioned on the ground.

[0009] Furthermore, a push-up handle of this type is known from publication US 2014 / 0135189 A1, but in this design, the handle unit is not secured against detachment from the base plate. Moreover, no restoring force is exerted on the handle unit, so it would automatically return to a neutral starting position when not under load. Additionally, the joint is not secured.

[0010] Reference is also made to the subsequently published document DE 10 2021 116 696 A1 as a further example of the state of the art.

[0011] The object of the invention is to provide an improved push-up handle and a training system for it, which prevents the aforementioned disadvantages of the prior art.

[0012] This problem is solved by the features of the independent patent claims. Advantageous embodiments of the invention are the subject of dependent claims.

[0013] The inventor recognized that a push-up handle can, on the one hand, perform a rotational movement around an axis of rotation, and on the other hand, that the axis of rotation can be freely movable around a pivot point within a predetermined spatial angle, with the components of the push-up handle being permanently connected to one another, thus preventing uncontrolled tilting or movement of the push-up handle. Additionally, the push-up handle can return to a neutral starting position when unloaded.

[0014] Furthermore, it is possible to limit the rotation angle during the turning movement of the handle.

[0015] Accordingly, the inventor proposes a push-up handle, comprising at least: a support plate for placing the push-up handle on a surface, a handle unit for supporting a user on the push-up handle, wherein the handle unit is movably mounted relative to the support plate so that, on the one hand, a rotational movement about an axis of rotation is possible and, on the other hand, the axis of rotation is freely movable about a pivot point within a predetermined spatial angle, a ball joint which is connected on one side to the support plate and on the other side to the handle unit, wherein the ball joint defines the spatial angle in which the free movement of the handle unit is possible, a rolling bearing which enables the rotational movement of the handle unit, wherein the axis of rotation of the handle unit passes through the longitudinal axis of the ball joint and the pivot point of the ball joint, and at least one spring which holds the handle unit in a neutral starting position.to improve it by providing a rotation angle limiting device which limits the rotational movement of the handle unit to a specific angular range.

[0016] The push-up handle according to the invention enables shoulder- and wrist-friendly training and the execution of various strength exercises such as push-ups, handstands, arm balances, and the like. An ergonomically shaped handle unit advantageously supports this. The base plate provides the push-up handle with a secure and stable footing on a surface, thus preventing uncontrolled slipping or tipping. The base area of ​​the base plate is advantageously significantly larger than the base area of ​​the handle unit and also larger than the projection area of ​​the handle unit when tilted to its maximum possible angle. In a simple embodiment, only one handle unit is movably mounted and attached to a base plate. Advantageously, this single handle unit is positioned centrally on the base plate.In other embodiments, more than one handle unit, preferably two handle units, are movably mounted and attached to a support plate. The advantage of the first embodiment with one handle unit per support plate is that the support plates can be positioned and spaced apart as desired for training, in order to accommodate the physical characteristics of different users. The support plate is, for example, designed as a flat disc and has a round, rectangular, or polygonal, particularly octagonal, shape.

[0017] According to the invention, the handle unit is movably mounted relative to the support plate. This mounting allows, firstly, the rotational movement of the handle unit about an axis of rotation and, secondly, the free movement of the axis of rotation about a pivot point within a predetermined spatial angle. The ball joint between the support plate and the handle unit defines the spatial angle for the movement of the handle unit. The rolling bearing enables the rotational movement of the handle unit. The axis of rotation of the handle unit, or of the rolling bearing, passes through the longitudinal axis and the pivot point of the ball joint.

[0018] Furthermore, at least one spring is provided to hold the handle unit in a neutral starting position. The handle unit is thus always returned from a deflected position to the neutral starting position by the at least one spring, i.e., without deflection of the ball joint or tilting of the handle unit. For this purpose, the at least one spring is advantageously relaxed and also neutral in the starting position. This positional stabilization greatly simplifies training with the push-up handle according to the invention and makes it suitable even for inexperienced users.

[0019] In a particularly advantageous embodiment, an intermediate plate is provided between the handle unit and the support plate, wherein the rolling bearing is located between the handle unit and the intermediate plate, and the ball joint is located between the intermediate plate and the support plate. The handle unit is thus movably, and in particular rotatably, connected to the intermediate plate. The intermediate plate is movably connected to the support plate by means of the ball joint.

[0020] The rotation angle limiting device according to the invention defines an angular range within which the rotation or rotary movement of the handle can take place, for example 90°, 180°, 270° or 360°. These angular ranges can be selected as desired, and angular ranges other than the aforementioned 90° increments are also possible.

[0021] In a preferred embodiment of the rotation angle limiting device, it comprises an elongated pin or bolt which, during rotation of the handle unit, moves between two stops, the stops defining the maximum possible angle of rotation of the handle unit. An angled section is particularly advantageous, which can be arranged between the handle unit and the intermediate plate. The angled section can be attached to the handle unit, for example by screwing it on, such that the pin is advantageously positioned laterally next to the intermediate plate and, during rotation of the handle unit, moves along the outer contour of the intermediate plate.

[0022] Advantageously, the stops are formed on the intermediate plate. For example, the stops are formed on the screws for fastening the fasteners, which are preferably guided through radial through-holes in the intermediate plate.

[0023] The stops can, for example, be positioned opposite each other on the intermediate plate, allowing for a 180° movement between them. Alternatively, the stops can be offset by 90°, allowing for a 90° or 270° movement, depending on which side of the intermediate plate the pin is positioned.

[0024] If the stops are formed on the screws that secure the fasteners, one embodiment provides that two screws or two stops define the angular range. For example, a 90° angular range is then formed by two stops or screws arranged at 90° intervals on the intermediate plate. During rotation, the pin moves at most from one screw or stop to the other screw or stop.

[0025] Another embodiment provides that only one screw or stop defines the angular range. This is preferably the case when the rotational movement is limited to 360°. In this case, the handle unit can perform a 360° rotation before it hits one stop and can then be rotated back in the opposite direction before it again hits the other side of the screw or stop.

[0026] In a simple embodiment, the rolling bearing is designed as a ball bearing. Advantageously, it exhibits very low rolling resistance, so that hardly any additional force needs to be exerted when rotating the handle unit.

[0027] The ball joint is connected to the intermediate plate on one side and to the support plate on the other, with the ball joint typically comprising a joint cup and a ball head. In a simple embodiment, the ball joint comprises a joint cup connected to the support plate and a ball head connected to the handle unit. A mechanical reversal of this embodiment is also within the scope of the invention. Furthermore, the ball head advantageously has a support rod for connection to the handle unit, wherein the longitudinal axis of the ball joint and the axis of rotation of the handle unit pass through the support rod. The support rod is attached to the ball head at one end, or one end of the support rod is designed as a ball head which sits in the joint cup. The other end of the support rod is rigidly connected to the intermediate plate.Advantageously, the support rod is designed as a threaded rod, at least in the area oriented towards the intermediate plate, so that the thread can be screwed into a bore in the intermediate plate. Consequently, when the handle unit and the intermediate plate are moved, the support rod or the ball joint moves within the joint housing. The base plate remains stationary. The joint housing is advantageously fixed to the base plate. For example, the joint housing also has a support or threaded rod, or is formed integrally with a threaded rod, wherein the threaded rod can be guided through a bore in the base plate and secured from below with a screw. Within the scope of this invention, the relative terms "above" and "below" always refer to the base plate, which is positioned below, i.e., on a surface, and the handle unit, which is located above and thus oriented towards the user.

[0028] As explained above, the at least one spring holds the handle unit in a neutral starting position relative to the support plate. Preferably, the at least one spring is arranged between the support plate and the intermediate plate. Advantageously, at least two springs are provided, arranged at opposite positions next to the ball joint. Furthermore, it is advantageous to arrange several springs symmetrically and at equal intervals around the ball joint to stabilize the starting position as uniformly as possible. When the handle unit is tilted with the intermediate plate, the elastic springs are compressed on one side and extended on the other.

[0029] As soon as no force is applied to the push-up handle, the spring force neutralizes the compression or extension of the springs and returns the handle unit from the tilted position to the starting position.

[0030] Another embodiment provides at least one stiffening element that at least partially prevents the deflection of the at least one spring. The deflection of the springs is thus prevented at least in one end region, i.e., at maximum tilting of the handle unit. The stiffening elements therefore stiffen the springs. Advantageously, there is one stiffening element per spring. The stiffening elements are, for example, designed as a type of pin that is inserted into the hollow cylindrical springs during assembly of the push-up handle. The ends of the springs and the pins are advantageously arranged in recesses in the support plate and the intermediate plate and are held there. Preferably, the projection of a pin beyond the support plate is smaller than the distance between the support plate and the intermediate plate, since otherwise tilting would be virtually impossible.

[0031] Another embodiment provides for at least one fastening element that connects the support plate to the handle unit. Preferably, this fastening element is elastic, for example, a type of tension strap or rubber bungee cord. This fastening element also prevents the handle unit or the intermediate plate from detaching from the support plate. For this purpose, the fastening element advantageously maintains tension in the connection between the support plate and the handle unit and also ensures that the handle unit returns to its starting position as soon as no forces are applied or when the push-up handle is not in use. In the neutral starting position, the fastening element is preferably slightly tensioned.For simplicity, the at least one fastening element is attached to the base plate on one side and to the intermediate plate on the other. Advantageously, the at least one fastening element is detachably attached; for example, the ends are detachably screwed to the intermediate plate and / or the base plate, or the ends can be hooked into the plates, or thickenings are formed at the ends that are inserted into recesses in the plates and thus held in place. For example, more than one fastening element is present, in particular three or four fastening elements, which are arranged at even intervals and distributed around the ball joint. A preferred embodiment provides that four springs with pins and four rubber straps are arranged alternately and at even intervals around the ball joint.

[0032] Another embodiment provides at least one additional locking element for the ball joint, which prevents the ball head from detaching from the joint housing. Advantageously, this locking element prevents the ball head from disengaging from the joint housing even at maximum deflection. For example, the locking element is designed as a wire rope that extends from the intermediate plate under or behind the ball housing through a hole in the support rod, thus preventing the ball head from detaching without restricting its free movement.

[0033] The push-up handle can be operated in different training modes, in which at least the free movement of the handle unit within the specified spatial angle is partially blocked and the handle unit is fixed in different positions. Accordingly, a locking element is advantageously provided that prevents the deflection of the ball joint.

[0034] To implement a first training mode, the locking element is designed in one embodiment such that the handle unit is held in the neutral starting position. This means that in this training mode, only the rotational movement of the handle unit via the ball bearing in the neutral starting position of the ball joint is possible, while the free movement of the axis of rotation within the spatial angle is blocked. For example, the locking element is designed as a flat disc with parallel upper and lower sides, which is inserted almost flush between the support plate and the intermediate plate, so that the handle unit and intermediate plate can no longer be tilted, as the disc prevents this tilting.

[0035] To implement another training mode, the locking element is designed in a different embodiment such that the handle unit is held in a tilted position. This means that in this training mode, only rotational movement of the handle unit via the ball bearing is possible, but the handle unit is held tilted and fixed in this position. For example, the locking element is designed as a more or less pointed wedge or wedge-shaped truncated wedge that is inserted between the support plate and the intermediate plate, so that the handle unit and intermediate plate are necessarily held in a tilted position. Depending on the wedge's design, different deflections or tilt angles can be set.

[0036] The handle unit of the push-up handle according to the invention is advantageously ergonomically designed. In a preferred embodiment, the handle unit is designed as a hemisphere, with the flat side of the hemisphere facing the intermediate plate and the curved side facing the user. Optionally, a further handle element can be provided that can be attached to the handle unit, for example, a cuboid, a rectangular plate, a smaller or larger hemisphere or sphere, or the like.

[0037] To facilitate easy handling of the push-up handle, at least one handle is provided on the support plate. In the simplest embodiment, the handle is designed as a grip-like recess on the edge of the support plate. Other embodiments, such as a bar or a loop on a side edge of the support plate, are also possible. Furthermore, the support plate advantageously has a non-slip material on its underside, for example, as a sticker or a surface coating, to ensure a secure grip. A material such as wood or plastic with a smooth surface is particularly suitable for the support plate, the handle unit, the intermediate plate, and the locking element, thus allowing for easy cleaning for hygienic reasons.

[0038] The invention further relates to a training system, comprising at least two push-up handles designed as described above. Particularly advantageously, a training system comprises two handle units, wherein the handle units are either movably mounted and fastened on a common support plate or on separate support plates.

[0039] The invention is described in more detail below with reference to a preferred embodiment and the figures shown, whereby only the features necessary for understanding the invention are shown.

[0040] They show in detail: Fig. 1: a schematic perspective view of a push-up handle according to the invention, Fig. 2: A schematic projection view onto the underside of the push-up handle according to the Fig. 1, Fig. 3: A first schematic cross-sectional view of the push-up handle according to the Fig. 1, Fig. 4: Another schematic cross-sectional view of the push-up handle according to the Fig. 1, Fig. 5: A schematic projection view of one side of the push-up handle according to the Fig. 1 in a tilted position, Fig. 6: a schematic cross-sectional view through the intermediate plate of a push-up handle in a further embodiment with a rotation angle limiting device, Fig. 7: A bottom view of an angled component of the rotation angle limiting device, Fig. 8: A side view of the angled component of the rotation angle limiting device, Fig. 9: A schematic cross-sectional view of the push-up handle according to the Fig. 6 with the rotation angle limiting device in a first angular position, and Fig. 10: A schematic cross-sectional view of the push-up handle according to the Fig. 6 with the rotation angle limiting device in a second angular position offset by 90°

[0041] The Fig. Figure 1 shows a schematic perspective view of a push-up handle according to the invention.

[0042] The push-up handle 1 has a base plate 2 that ensures a stable and non-slip grip on a surface. In the exemplary embodiment shown here, the base plate 2 is designed as an octagonal, flat wooden disc. A grip unit 3 is positioned centrally on the base plate 2. In this exemplary embodiment, the grip unit 3 is designed as a hemisphere. The user rests their hand on the grip unit 3 during training. The curvature of the hemisphere faces upwards, so that it rests ergonomically in the user's palm.

[0043] An intermediate plate 4 is formed between the handle unit 3 and the support plate 2, wherein the handle unit 3 and the intermediate plate 4 are movably connected to each other. The intermediate plate 4 is designed as a flat circular disk and has a slightly smaller diameter than the hemispherical handle unit 3.

[0044] The handle unit 3 is movably mounted relative to the support plate 2. This mounting allows, firstly, rotational movement about an axis of rotation D, where the axis of rotation D is perpendicular to the center of the support plate 2 and thus runs perpendicularly through the center of the handle unit 3. For this purpose, a rolling bearing designed as a ball bearing 5 is provided between the handle unit 3 and the intermediate plate 4, which enables extremely low-friction rotational movement of the handle unit 3. Secondly, the mounting allows the handle unit 3 to move freely within a predefined spatial angle. For this purpose, a ball joint 6 is provided, which is connected to the support plate 2 on one side and to the handle unit 3 on the other. The ball joint 6 defines the spatial angle within which the handle unit 3 can move freely. The longitudinal axis L of the ball joint 6 runs in line with the axis of rotation D of the handle unit 3 and through the pivot point.

[0045] According to the Fig. In the first position, the handle unit 3 is in its neutral starting position, i.e., it is not tilted. According to the invention, in the embodiment shown here as an example, four springs 7 are provided. The springs are arranged at equal intervals around the center of the support plate 2, i.e., around the axis of rotation D. In the neutral starting position shown here, the springs 7 are not under tension. A pin-shaped stiffening element 8 is arranged in each of the hollow cylindrical springs 7, see figure 1. Fig. 3 to Fig. 4. The pins 8 make it more difficult for the springs 7 to bend and stiffen them, see Fig. 5.

[0046] Furthermore, four fastening elements 9 are provided, designed as elastic rubber strakes 9 and stretched between the intermediate plate 4 and the support plate 2. The rubber strakes 9 maintain tension in the connection between the support plate 2 and the intermediate plate 3, or the handle unit 3, and also ensure a return to the neutral starting position. One end of each rubber strake 9 is firmly connected to the intermediate plate 4. From there, the rubber strakes 9 extend through holes 2b in the support plate 2 and, approaching from below, are hooked into recesses 2a in the support plate 2 by means of a thickening 9a at the other end. In the embodiment shown here as an example, the upper ends of the rubber strakes 9 are fixed to the intermediate plate 4 by means of screws, which are guided from the outside to the inside through radial through-holes 4a.

[0047] The Fig. Figure 2 shows a schematic projection view of the underside of the push-up handle 1 according to the Fig. 1. The octagonal support plate 2 and, centrally, the round projection of the intermediate plate 4, as well as the slightly larger round projection of the handle unit 3, are visible. The ball joint 6 is located in the middle. The four springs 7 are positioned around it. A pin 8 is arranged in each of the springs 7.

[0048] Between the springs 7, the rubber slings 9 are passed through the holes 2b in the support plate 2 and stretched from there to the side edges of the support plate 2, where they are hooked into the recesses 2a of the support plate 2 with end thickenings 9a.

[0049] The Fig. Figure 3 shows a first schematic cross-sectional view of the push-up handle 1 according to the Fig. 1. The cross-section runs along the line in the Fig. The indicated line A-A is shown in Figure 2. The structure of the ball joint 6 is particularly evident in this cross-section. It should be noted that the representation of the ball joint 6, especially the joint cup 6a and the ball head 6b, is highly simplified schematically for clarity. The ball joint 6 comprises a joint cup 6a, which is connected to the support plate 2. A threaded rod 6c is formed on the joint cup 6a for this purpose. This rod sits in a central through-hole in the support plate 2 and is secured from below by a screw (not shown). The threaded rod 6c and the joint cup 6a are formed as a single piece.

[0050] Furthermore, the ball joint 6 comprises a rod end 6b, which is arranged in the joint cup 6a and connected to the intermediate plate 4. For this purpose, a threaded rod 6d is also formed on the rod end 6b, which is screwed into a central bore in the intermediate plate 4. The threaded rod 6d and the rod end 6b are formed as a single unit.

[0051] Furthermore, a safety element in the form of a wire rope 6f is provided, which prevents the ball joint 6b from detaching from the joint cup 6a when the ball joint 6 is at its maximum deflection. The wire rope 6f is attached at both ends to the intermediate plate 4 and passes under the joint cup 6a through a hole 6e in the threaded rod 6c.

[0052] The longitudinal axis L of the ball joint 6 corresponds to the axis of rotation D of the handle unit 3.

[0053] This cross-section also extends through two springs 7 arranged on either side of the ball joint 6, with pins 8 positioned therein. The ends of the springs 7 are each arranged in recesses in the intermediate plate 4 and the support plate 2, respectively. The pins 8 are inserted into the springs 7 from below through through-holes in the support plate 2. The projection of a pin 8 from the through-hole or beyond the support plate 2 is less than the distance from the support plate 2 to the intermediate plate 4. Furthermore, the upper ends of the springs 7 are chamfered. The pins 8 do not completely prevent the deflection of the springs 7, but only partially, see [reference]. Fig. 5.

[0054] Between the intermediate plate 4 and the handle unit 5, the ball bearing 6 is also indicated, which enables the rotational movement of the handle unit 3 around the axis of rotation D.

[0055] The Fig. Figure 4 shows another schematic cross-sectional view of the push-up handle 1 according to the Fig. 1. The cross-section runs along the line in the Fig. The indicated line B-B in Figure 2 shows the path of the rubber bungee cord 9. Each rubber bungee cord 9 has a holder 9b at the end fixed to the intermediate plate 4. This holder is inserted into a recess in the intermediate plate 4 and secured there by screws. The screws are guided through radial through-holes 4a from the outside through the intermediate plate 4. The rubber bungee cord 9 is guided under tension through holes 2b in the support plate 2 and stretched outwards, where its end thickenings 9a engage in recesses 2a at the edge of the support plate 2.

[0056] Furthermore, in this cross-sectional view, the hole 6e in the lower threaded rod 6c of the joint shell 6a can also be seen, through which the wire rope 6f is guided.

[0057] The Fig. Figure 5 shows a schematic projection view of one side of the push-up handle 1 according to the Fig. 1 in a tilted position. The handle unit 3 is tilted here relative to the support plate 2 by an angle of approximately 30°. This means that the axis of rotation D of the handle unit 3 is inclined within the spatial angle defined by the ball joint 6, and the handle unit 3 can be rotated about the inclined axis of rotation D. The pivot point for the inclination of the axis of rotation D is the ball joint 6.

[0058] The tilting of the push-up handle 1 shown here illustrates the maximum possible deflection or tilting, as the pins 8 in the springs 7 prevent further tilting. The upper ends of the pins 8 abut laterally against the intermediate plate 4, preventing it from tilting further. The rubber strap 9 on the right side of the image is under tension, as are the springs 7. Simultaneously, the springs 7 on the left side of the image are compressed, so that if the user releases the force applied to the handle unit 3, it returns to its neutral starting position.

[0059] The following Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. Figure 10 shows the push-up handle 1 in a further embodiment with a rotation angle limiting device 10 for defining the angular range in which the handle unit 3 can be rotated, as well as components of the rotation angle limiting device 10. The following discussion focuses solely on the differences compared to the embodiment shown in the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. Figure 5 describes the embodiment shown and the essential features of the angle limitation. Identical components are marked with the same reference numerals.

[0060] The Fig. Figure 6 shows a schematic cross-sectional view through the intermediate plate 4 of the push-up handle 1 in an embodiment with a rotation angle limiting device 10. The cross-sectional plane runs centrally through the intermediate plate 4, with the viewing direction directed towards the handle unit 3, i.e. upwards.

[0061] The angled part 11 of the rotation angle limiting device 10 is positioned between the intermediate plate 3 and the handle unit 4, with the angled part being screwed to the underside of the handle unit 3.

[0062] As in the Fig. 7 and Fig. As can be seen in Figure 8, the angled part 11 has a flat area which is arranged between the intermediate plate 4 and the handle unit 3 and has three holes 11a for screws for fastening to the underside of the handle unit 3. The angled part 11 is approximately triangular in shape, with one corner area folded and an elongated pin 12 attached there.

[0063] The corner area with the pin 12 extends beyond the edge of the intermediate plate 4, so that the pin 12 is positioned directly on the surface of the intermediate plate 4.

[0064] In the cross-sectional view of the Fig. Figure 6 shows the four fastening screws for the rubber strap 9, which are inserted into radial through-holes 4a. The through-holes 4a are evenly distributed around the circumference of the intermediate plate 4, i.e., at 90° intervals. Longer screws 13 are inserted into two of the four through-holes 4a and protrude from the intermediate plate 4. Round nuts 14 are fitted onto these end sections of the screws 13, serving as stops for the pin 12. In this exemplary embodiment, the two stops are arranged opposite each other on the intermediate plate 4, allowing the pin 12 to move back and forth within a 180° range between the stops. The rotational movement of the handle unit 3 is thus limited to an angle of 180°.

[0065] The Fig. 9 and Fig. Figure 10 shows cross-sectional views of the push-up handle with the rotation angle limiting device 10 at two different angular positions.

[0066] According to the Fig. The cross-sectional plane 9 passes through the pin 12, which is located on the outer surface of the intermediate plate 4. The flat area of ​​the angled part 11 is positioned between the handle unit 3 and the intermediate plate 4 and is fastened to the handle unit 3 with three screws 11b.

[0067] According to the Fig. The cross-sectional plane 10 passes through two opposing through-holes 4a, with a longer screw 13 being inserted in one of the through-holes 4a, protruding from the intermediate plate 4. The round nut 14 on the end of this screw 13 forms a stop for the pin 12.
