Description

[0001] The invention relates to a gymnastic and sports apparatus designed as a wall bar, which is configured to be fixed in a door or wall opening, with two lateral cheeks which are configured to be vertically aligned and clamped in the door or wall opening between a floor and an upper edge that limits the top of the door or wall opening, and which have mutually facing inner surfaces, wherein the inner surfaces each have several recesses which are arranged at different heights and opposite each other, and with at least one rung which is configured to be held in use with its two ends in two recesses of the same height in the two cheeks, wherein each cheek has two upper and lower parts arranged one above the other, the upper part of which is designed as a clamping element which is height-adjustable relative to the lower part.Because multiple mounting points are arranged one above the other, a correspondingly large number of rungs can be incorporated into the gymnastic and sports equipment, allowing it to be described as a wall bar. Alternatively, a smaller number of rungs, or even just a single rung, can be mounted, with the multiple mounting points arranged one above the other allowing the height of the rung to be adjusted to different gymnastic exercises or body sizes.

[0002] A gymnastic and sports device of this type is known from US Patent 4,657,242 A. The clamping piece has a downward-projecting pin that extends into a recess opening into the top of the lower part. Two horizontally running clamping screws arranged side by side serve to fix the clamping piece at the selected height.

[0003] The invention is based on the objective of improving a generic gymnastic and sports apparatus in such a way that the clamping piece can be adjusted in height as easily as possible and fixed at the respective set height, so that firstly, the gymnastic and sports apparatus is fixed as securely as possible in the door or wall opening and secondly, the gymnastic and sports apparatus can be easily removed from the door or wall opening.

[0004] Features according to the invention are specified in claim 1. Embodiments are the subject of the dependent claims.

[0005] The invention thus proposes that the clamping element and the lower part overlap in the upper region of the lower part, and that the clamping element is height-adjustable relative to the lower part by means of a single clamping screw, is movable along a predetermined path relative to the lower part by means of a cam guide, and can be fixed to the lower part by means of at least one clamping screw. The cam guide can be created in the area of ​​overlap so that the clamping element is height-movable along the path predetermined by the cam guide, for example, along a curve or, particularly simply, along a straight line, e.g., a vertical path. Undesired tilting or canting of the clamping element relative to the lower part is prevented by the cam guide. Since the height adjustment of the clamping element is effected by means of a single clamping screw, the height adjustment is quick and easy.

[0006] Furthermore, the thread of the clamping screw typically provides a self-locking mechanism, for example, if the clamping screw is equipped with a metric ISO thread M6, M8, or M10. This self-locking effect means that the clamping piece is not freely movable vertically when axial forces act on the clamping screw; rather, the clamping piece retains the height set by the clamping screw. This is advantageous when the cheek is to be clamped vertically within the door or wall opening and the clamping piece is adjusted upwards for this purpose until it rests against the upper edge of the door or wall opening with the desired contact pressure.Even after the clamping screw is released, the clamping element retains its position and thus the desired clamping pressure despite the vertically acting clamping forces; to adjust the clamping screw, it must instead be rotated around its longitudinal axis. This allows the gymnastic and sports equipment to be mounted and held particularly reliably and securely within the door or wall opening, absorbing the forces that occur during use.

[0007] The additional clamping screw serves to secure the clamping piece to the lower part of the cheek at the height initially set using the clamping screw, reliably preventing accidental loosening or adjustment of the clamping piece. Compared to using multiple clamping screws, the use of a single clamping screw allows for particularly easy height adjustment of the clamping piece, as it eliminates the need to operate and balance several clamping screws sequentially to ensure the clamping piece maintains its desired orientation, e.g., a perfectly horizontal top surface. This straightforward and therefore quick handling facilitates both the installation of the gymnastic and sports equipment in a doorway or wall opening and its subsequent disassembly.

[0008] In one embodiment, the gymnastic and sports equipment is characterized by the fact that a nut is associated with the clamping screw, with which it interacts. The clamping screw does not interact directly with the material of the lower part or the clamping element by means of a thread cut into the lower part or the clamping element, but rather, regardless of the material used, a separate nut is provided that supplies the internal thread with which the clamping screw interacts. In this way, high clamping forces can be ensured, irrespective of the material used for the clamping element or the lower part, e.g., wood or plastic, while the nut can be made of a material subjected to higher stress, such as steel.

[0009] For example, the nut can be a threaded sleeve that is slidably guided in a groove in the lower part and transmits the required clamping forces to the lower part by means of a T-shaped cross-section. In this case, the clamping screw can, for example, be fixed to the clamping piece and move vertically relative to the lower part along with the clamping piece and the threaded sleeve. According to another example, the nut can be a T-nut that is fixed in place, e.g., on the lower part, and a groove can run through the vertically movable clamping piece through which the clamping screw extends into the nut, so that the clamping screw maintains its position while the clamping piece is adjusted vertically.

[0010] In one embodiment, the gymnastic and sports apparatus is characterized by a guide rail designed as a track running longitudinally along the cheek, guiding the clamping element along the same length. Compared to a curved or inclined guide rail, this design allows for vertical movement of the clamping element when the cheek is vertically oriented in the door or wall opening. This ensures that the clamping element's height can be adjusted as directly and immediately as possible by operating the clamping screw. Consequently, the clamping element's height adjustment is not hindered by forces that might otherwise act on it in a direction deviating from the vertical.

[0011] In one embodiment, the gymnastic and sports equipment is characterized by the fact that the clamping screw interacts with a transverse nut bolt located in the lower part of the cheek. The design of the nut as a transverse nut bolt advantageously results in a large-area transmission of the clamping forces to the component receiving the transverse nut bolt, for example, the lower part of the cheek. Accordingly, high clamping forces can be applied, ensuring a secure hold of the gymnastic and sports equipment in the door or wall opening without the risk of undesirable settling movements within the cheek that would lead to an undesirable reduction in clamping forces.

[0012] A captive mounting of the clamping piece to the base can be achieved, for example, by crimping a few threads of the vertical clamping screw, so that the clamping piece is vertically movable relative to the base, but cannot be completely detached from it. In one embodiment of the gymnastic and sports equipment, the clamping piece is characterized by being interchangeably connected to the base. Foregoing the aforementioned captive mounting allows the clamping piece to be deliberately detached from the base, so that it can, for example, be replaced with a different clamping piece.

[0013] The different designs of the clamping pieces can relate, for example, to the contact surface with which the clamping piece is applied to the upper edge of the door or masonry opening from below: for instance, this contact surface can have a high coefficient of friction, i.e., be designed to be slip-resistant. Or it can be provided with an adhesive layer, which, depending on the strength of the adhesive effect, can be referred to as a bonding layer or adhesive layer. Or the contact surface can have a U-shaped contour that forms a positive fit around the upper edge of the door or masonry opening, so that the jamb is particularly reliably secured against acting horizontal transverse forces. Furthermore, the different designs of the clamping pieces can relate, for example, to the height of the respective clamping piece, e.g., to adapt to the specific height of the door or masonry opening.

[0014] In one embodiment, the gymnastic and sports equipment is characterized by the fact that the lower parts of the cheeks each have two or more sections arranged one above the other below the clamping element, wherein the sections are optionally detachable from one another or connectable to one another. The multi-part construction of the lower part can also serve to adapt to door or masonry openings of varying heights, particularly when sections of different heights are provided and can be combined in different ways. The multi-part construction of the lower part is particularly advantageous for transport reasons, as the gymnastic and sports equipment can be transported by the customer themselves or shipped with advantageously small packaging dimensions.

[0015] In one embodiment, the gymnastic and sports equipment is characterized by the fact that the cheeks each have two adjacent strips, one of which, an inner strip, forms the inside of the cheek and is equipped with the receptacles. For example, the strips can be made of wood or plastic. The strips can be glued and / or screwed together. The construction of the lower part from two strips makes it easy and economical to create the receptacles in the so-called inner strip, which forms the inside of the cheek. For this purpose, the inner strip can, for example, be provided with recesses that extend through its entire thickness, so that no complicated pockets need to be created in the cheek that only cover a certain proportion of the material thickness of the component being worked on.Rather, such pockets can be created by connecting the inner strip with the recesses to the outer strip, which faces the door frame or the masonry surrounding the opening. The outer strip protects the door frame or the masonry from damage that could otherwise be caused by a rung of the gymnastic or sports equipment inserted into the recesses, if this rung comes into contact with the door frame or the masonry.

[0016] The modular design of the cheek with two strips also offers the possibility of designing each of the two strips in different variations, for example with different colors, different layer thicknesses or made of different materials, so that the cheek can be configured differently with comparatively little effort, depending on static requirements or customer wishes.

[0017] In one embodiment, the gymnastic and sports equipment is characterized by the fact that in the areas where the lower part and the clamping piece of a cheek overlap, the cheeks each have two adjacent strips, and the contacting surfaces of these two strips form the cam track. The two contact surfaces of the two strips are easily accessible for machining, allowing the desired cam track to be created in a structurally simple manner. For example, a groove can run through one contact surface, and the other contact surface can have a projection or an elongated rib that is longitudinally displaceable within the groove.

[0018] In one embodiment, the gymnastic and sports equipment is characterized by the fact that the cheeks have a layer of anti-slip material at their upper and / or lower ends. For example, the layer can consist of a rubber-like elastomer material. In addition to the choice of material used, the surface of the layer, which is intended to contact the floor or the top edge of the door or masonry opening, can have a roughness that increases the frictional resistance of this anti-slip layer.

[0019] Because compressive forces act on the cheeks from both above and below along their length, they are subjected to buckling and tend to bulge in their central area. Since the cheeks rest against the side edge of the door or masonry opening with their respective outer surfaces, this bulging can only develop in the direction of the opposite cheek. The bulging of the cheeks is disadvantageous because it reduces the distance between the two cheeks, making it difficult or even impossible to insert a muntin in the bulged area. Alternatively, it can cause a muntin already in place to be wedged so tightly between the two cheeks that it can only be removed with significantly increased force, or not at all, or at least not without damage.Secondly, the design of the belly reduces the distance between the upper and lower contact surfaces of the cheek, thus diminishing the original tension forces that were intended to reliably clamp and secure the cheek in the door or masonry opening. This significantly increases the risk of the gymnastic or sports equipment unintentionally detaching from the door or masonry opening due to the forces acting on the cheeks during use, thereby posing a risk of injury to the user and potentially to anyone nearby.

[0020] Therefore, in one embodiment, the gymnastic and sports equipment is characterized in that each side panel has a contact surface designed to rest against the floor or the upper edge of the door or masonry opening. This contact surface is inclined at an angle of between 1° and 10° relative to the longitudinal axis of the side panel and to the opposite side panel in such a way that, when the side panel is clamped between the floor and the upper edge of the door or masonry opening, it automatically rests flush against the side edge of the door or masonry opening. The angle of inclination encourages the side panel to tilt, preventing it from tilting inwards towards the center of the door or masonry opening and thus towards the opposite side panel, but rather outwards where it rests against the side edge of the door or masonry opening.

[0021] The tendency to develop a bulge due to the pressure forces acting from above and below is therefore counteracted by a particularly firm fit of the cheek against the side edge of the door or masonry opening, and this side edge prevents the cheek from bulging. The disadvantages associated with bulges are thus avoided, and the safety of the gymnastic and sports equipment is significantly improved. Due to the angle of inclination, which can also be described as a slanted cut of the contact surface, the cheek self-fits to the door frame under its own force. The flush fit is achieved without additional cover strips, profiles, or trim – i.e., without additional components that would need to be manufactured, installed, and potentially adapted on-site to the existing conditions. The flush fit of the cheek ensures an even distribution of force along the door frame.The angled contact surface creates a higher contact force between the cheek and the vertical side edge of the door or masonry opening, resulting in higher frictional forces when forces act on the gymnastic or sports equipment perpendicular to the plane of the door or masonry opening, thus ensuring a particularly secure hold of the gymnastic or sports equipment in the door or masonry opening.

[0022] The cheek can have an obliquely cut contact surface at its upper or lower end. In one embodiment, the gymnastic and sports equipment is characterized in that both the clamping piece and the lower part have an obliquely running contact surface, i.e., both the upper and lower ends of the cheek have an obliquely cut contact surface.

[0023] In one embodiment, the gymnastic and sports equipment is characterized by the fact that the angle of inclination of the contact surface is between 1° and 5°. This relatively small angle of inclination ensures that the contact surface rests against the corresponding floor or the upper edge of the door or masonry opening not only with a relatively narrow, strip-like area due to its angled cut, but rather with as much of its surface contact as possible. Particularly when the contact surface is designed to be slip-resistant, slightly adhesive, or even highly adhesive, this near-full-surface contact promotes the most secure possible fixation of the gymnastic and sports equipment in the door or masonry opening.

[0024] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the purely schematic drawings. These show: Fig. 1 A perspective view of a gymnastic and sports apparatus, Fig. 2 one cheek of the gymnastic and sports equipment of Fig. 1 in expanded view, Fig. 3 a section of the cheek of Fig. 2 in expanded view, Fig. 4 a perspective view of the inside of a clamping piece of the cheek of Fig. 2, Fig. 5 a perspective view of the outside of the clamping piece of Fig. 4, and Fig. 6 the lower area of ​​a cheek with an obliquely cut contact surface.

[0025] Fig. Figure 1 shows a gymnastic and sports apparatus 1, which is designed to be set up and secured within a doorway or masonry opening. The gymnastic and sports apparatus 1 has two side panels 2 and is equipped, purely by way of example, with two rungs 3, which in the illustrated embodiment are designed as tubes made of an extruded aluminum profile and which have a profile in the form of several grooves on part of their circumference.

[0026] The cheeks 2 each have an inner side facing the opposite cheek 2, and an outer side facing the side edge of the opening that accommodates the gymnastic and sports equipment 1. Each cheek 2 has an upper clamping element 4 and below it a lower section 5, which comprises most of the cheek's height. The lower sections 5 do not extend in one piece over their entire height, but consist of several superimposed sections 6; in the illustrated embodiment, there are two such sections 6, each connected by a connecting tab 7. Similarly, the cheeks 2 do not extend in one piece over their entire thickness, but consist of two adjacent strips: an outer strip 8 and an inner strip 9. This applies to both the clamping elements 4 and the lower sections 5.

[0027] In the illustrated embodiment, all connections are made by screws, with each screw being received in a threaded sleeve: this applies to the connection of the clamping piece 4 to the lower part 5, as well as the connection of the individual sections 6 to the connecting tab 7, and also the connection of the outer strips 8 to the inner strips 9. Both the screws and the threaded sleeves each have a T-shaped cross-section with a shank and a circumferential collar, so that components can be clamped between the two collars and held securely together when the screw connection is tightened. Stepped bores have been provided in the outer strips 8 of the cheeks 2, so that the collars of the screw connections located there can be received flush in the outer strips 8 and do not form an obstructive, outwardly projecting protrusion that could damage a door frame or masonry.

[0028] The inner strips 9 of a cheek 2 have several superimposed, approximately L-shaped, downwardly angled recesses, each forming a receptacle 10 into which a rung 3 can be selectively inserted and securely held, or from which a rung 3 can selectively be removed. The rung 3 is secured in the receptacles 10 against downward forces. The lowest receptacle 10 of each cheek 2 also offers this possibility. However, unlike the other receptacles 10, it is designed to be approximately Y-shaped, so that a rung 3 can also be received and secured against upward forces where the otherwise approximately L-shaped course of the receptacle 10 has its angle. To securely hold a rung 3 in this upper area of ​​the lowest, Y-shaped receptacle 10, an approximately L-shaped insert 11 is inserted into the lowest receptacle 10.It is held magnetically in this position and can be removed without tools if necessary and reinstalled there after inserting rung 3.

[0029] Fig. Figure 2 shows a cheek 2 in an expanded view. Of the screw connections shown, screws 12 are arranged in the inner strips 9 and threaded sleeves 13 in the outer strips 8. The lower edge of the lower section 6 and the upper edge of the clamping piece 4 form the lower and upper contact surfaces 14 of the cheek 2, and in the illustrated embodiment, the contact surfaces 14 are provided with a layer 15 of anti-slip material. In the illustrated embodiment, a mass is not applied to the respective contact surface 14 for this purpose, but the layer 15 consists of a flat section of material, for example, a piece of material punched out from a rubber sheet several millimeters thick or from an elastomer film.

[0030] Furthermore, it shows Fig. 2 a clamping screw 16 which interacts with a transverse nut bolt 17. A receiving bore 18 in the upper area of ​​the upper section 6 of the lower part 5 serves to receive the transverse nut bolt 17 and hold it in a height-fixed position, so that actuation of the clamping screw 16, which is held in the clamping piece 4, causes a height adjustment of the clamping piece 4.

[0031] In Fig. In Figure 2, four square-arranged bores for receiving clamping screws 21 are visible near the receiving bore 18, while the associated threaded sleeves 13 extend through elongated holes 19 that penetrate the outer strip 8 of the clamping piece 4. This creates a cam guide that ensures the clamping piece 4 can only move up and down along a predetermined path, in the illustrated embodiment in the longitudinal direction of the cheek 2 and thus in the vertical direction when the cheek 2 is arranged vertically in the door or masonry opening. A central elongated hole is located between the two elongated holes 19 and serves to receive the transverse nut bolt 17 and, despite its fixed mounting in the inner strip 9 of the lower part 5, to allow vertical movement of the clamping piece 4 relative to the lower part 5.

[0032] The clamping screws 21 are designed in the same way as the screws 12. However, while the other screws 12 serve to firmly connect two components, the clamping screws 21 serve to first allow the relative movement of two components that are movable relative to each other - clamping piece 4 and lower part 5 - and then, when the clamping piece 4 has been brought to its desired height and the cheek 2 has been clamped in the door or masonry opening, to fix these two components in their relative position to each other.

[0033] Fig. Figure 3 shows the upper section 6 of a lower part 5, with the receiving bore 18 for the transverse nut bolt 17. The receiving bore 18 is located in a groove into which the clamping screw 16 engages. Furthermore, it is made of Fig. Figure 3 shows that stepped bores 20 are arranged in the outer strip 8, so that the collars of the threaded sleeves 13 can be received flush within the outer strip 8. In the lower area of ​​the inner strip 9, two through holes are visible, and since the inner strip 9 projects further downwards than the outer strip 8, two screws 12, which serve to secure a connecting tab 7, can be passed through these through holes.

[0034] Fig. Figure 4 shows a clamping element 4 with a view of its inner side. The lower edge of the inner strip 9 of the clamping element 4 rests on the screw head of the clamping screw 16, so that by turning the clamping screw 16 the clamping element 4 can be raised or, with the aid of gravity, lowered. The outer strip 8 of the clamping element 4 slides along the transverse nut 17, which is arranged at a fixed height, via the central elongated hole, while the two outer elongated holes 19 form part of the aforementioned cam guide, which ensures exclusively vertical movement of the clamping element 4 and helps to prevent tilting or misalignment of the clamping element 4 relative to the lower part 5 of the cheek 2.

[0035] Fig. Figure 5 shows the clamping piece 4 from its outer side. It can be seen that the elongated holes 19, similar to the stepped bores 20, form a receiving space for the collars of the threaded sleeves 13.

[0036] Fig. Figure 6 shows the lower area of ​​a lower section 6 of a lower part 5, and thus the lower contact surface 14 of the respective cheek 2. Here too, it is evident that the contact surface 14 is provided with a layer 15 of anti-slip material. Due to the larger scale compared to the other drawings, in Fig. Figure 6 clearly shows that the lower contact surface 14 of the cheek 2 runs at an angle of inclination α. ​​This angle of inclination, relative to the cross-section of the cheek 2, does not run longitudinally, but perpendicular to it, namely towards the opposite cheek 2 and thus in the direction in which, for example, a wall extending which contains the door or masonry opening, extends. Due to the angle of inclination α, the contact surface 14 is designed such that it rises outwards and slopes downwards inwards, towards the opposite cheek 2.

[0037] Assuming that the inclination angle α is not produced in a primary forming process, e.g. in a casting process or an additive manufacturing process, during the production of the cheek 2, but rather by a post-processing of the cheek 2 or the lower part 5 or the lower section 6 or the lower outer strip 8 and the lower inner strip 9, namely by a machining process, this design of the lower contact surface 14 is also referred to as an obliquely cut contact surface 14.

[0038] Fig.Figure 6 shows the lower contact surface 14 of a cheek 2. The upper contact surface 14 of the cheek 2 can also be cut at an angle, so that alternatively either the lower or the upper, or both contact surfaces 14 can be cut at an angle. The angle of inclination α of the upper contact surface 14 is symmetrical to that of the lower contact surface 14, i.e., it slopes downwards towards the outside and increases inwards towards the opposite cheek 2.

[0039] When the cheek 2 is clamped between a floor and the upper edge of the door or masonry opening by adjusting the clamping piece 4 upwards relative to the lower part 5 using the clamping screw 16, compressive forces act on the cheek 2 from above and below in the longitudinal direction. Beyond a certain magnitude of compressive forces, the cheek 2 tends to yield to these forces by forming a bulge, with the bulge pointing inwards, namely towards the opposite cheek 2. The angled contact surface 14 causes the cheek to tilt outwards as the compressive forces build up, thus counteracting the formation of a bulge and automatically pressing the cheek 2 firmly against the vertical side edge of the door or masonry opening.

[0040] The invention is not limited to one of the embodiments described above, but can be modified in a variety of ways. All features and advantages arising from the claims, the description, and the drawings, including design details, spatial arrangements, and process steps, can be essential to the invention both individually and in various combinations.
