Description

[0001] The invention relates to a gymnastic and sports apparatus for fastening in a door or wall opening, with two support struts to be arranged vertically between the floor and the door or wall opening, which have receptacles on their inner sides for at least one gymnastic bar to be positioned in a transverse direction to the support struts.

[0002] Such gymnastic and sports equipment is primarily intended for installation in doorways or wall openings of private rooms, such as children's bedrooms, and is known from, among others, DE 199 13 044 A1, US 4657141 A, and US 4772011 A. US 4657242 A and DE 102011110181 B4 also describe similar gymnastic and sports equipment that can be installed in doorways or wall openings and secured there by clamping or tensioning. Thanks to its integration into these doorways or wall openings, the equipment offers the advantages of an exercise or fitness device with a certain degree of stability, without taking up significant space. No frame is required; instead, such an inner frame, consisting of support struts, is detachably attached to the existing door frame or jamb. After installing a gymnastic bar in the lateral support struts, exercises such as pull-ups can then be performed on the bar.Installing a swing set is also remarkably simple. The main disadvantage of existing solutions is that their fastening is inadequate to withstand the lateral forces that occur during use. With increased stress in this direction, there is a risk that parts of the swing set, and consequently the entire swing set, could break free from its fixings. This can lead to significant health problems for users, especially if the structure suddenly collapses.

[0003] The present invention therefore aims to create a gymnastic or sports device that can be safely installed in a door or wall opening with minimal effort and offers a variety of possibilities for installing crossbars or pull-up bars.

[0004] This problem is solved by the technical features of claim 1.

[0005] This ensures a reliable and secure connection between the gymnastic and sports equipment, specifically the support struts forming an inner frame, and the door or wall opening, while also protecting the door frame. Furthermore, any type of gymnastic bar can be securely inserted into the recesses provided on the inside of the support struts. These recesses, such as angled and circular ones, are located at regular intervals within the support struts. Crossbars, such as round or oval wooden rungs or standard pull-up bars with screw threads, can be inserted into these recesses.

[0006] Because the support struts are equipped at their upper end with a clamping block for adjusting them between the floor and the door or wall opening, the component for adjusting the height of the support strut is located at the upper end of the support struts in the form of the clamping block when installing the device according to the invention. This simplifies installation, as only the comparatively lightweight clamping blocks need to be adjusted in height, instead of the entire support struts. To do this, the clamping block is adjusted in height until its upper surface rests firmly and securely against the underside of the door or wall opening.

[0007] Specifically, this works as follows: the clamping block is fixed to the upper end of the corresponding support strut via a pair of threaded mounting rods, and the height of the clamping block is adjustable by turning a nut that interacts with each threaded rod. Installation and disassembly are thus further simplified because only the threaded rods need to be adjusted via a nut, the turning of which simultaneously and inevitably adjusts the height of the clamping block.

[0008] Previously known gymnastic and sports equipment of this type typically features round receptacles for a gymnastic bar installed transversely to the support struts. The present invention takes this a significant step further by providing the receptacles with a guide track featuring at least one angle for inserting the gymnastic or pull-up bar, which offers several advantages. For example, it prevents children from using the device according to the invention without first ensuring the rungs are securely inserted into the designated receptacles. Thanks to the guide track, the gymnastic bar, inserted transversely into the support struts, automatically assumes its position and remains permanently fixed there.The gymnastic apparatus according to the invention forms a substructure in such a way that no direct, force-fit tensioning between the crossbar or pull-up bar, which is adjustable in length, and the door frame is necessary.

[0009] A fixed and rotatable rung provides an additional level of safety. Furthermore, it allows for exercises that would be impossible with a potentially rotating bar. Therefore, the use of a pull-up or gymnastic bar with an oval cross-section is recommended, where the width of the guide rail and the smallest diameter of the bar are precisely matched. The corresponding design of the bar and guide rail ensures that the bar can only be inserted in the correct position. The guide rail thus prevents the pull-up bar from rotating.

[0010] Ultimately, any guide track with a securely fixed final position for the rung is suitable. A particularly suitable guide track is created when the guide track extends initially perpendicular to the longitudinal axis of the support strut and, after bending, downwards in the direction of the support strut's longitudinal axis. In this track, the bar, after rotating approximately 90° at the bend, essentially assumes its correct position automatically. Such a guide track thus has two chambers arranged in succession: a first into which the bar is inserted and a second, offset by approximately 90°, in which it can assume its final position. That is, after inserting the bar into the first chamber, it essentially slides down by itself into the second chamber, which is preferably arranged at a right angle to the first. There, thanks to its oval cross-section, the bar is held firmly and securely against rotation.

[0011] A particularly advantageous embodiment of the invention is realized when a clamping position for the gymnastic bar is provided in the transition between the two chambers, i.e., in the area of ​​the bend, in which it is held between the inner and outer flanks of the guide track. In addition to the aforementioned lower position, in which the rung sits in the rear chamber, a clamping position is conceivable in which the bar is wedged, making it particularly suitable for gymnastic exercises such as sit-ups.

[0012] Specifically, this means that a recess is provided in the angled section, in which the gymnastic bar is held in a clamping position rotated at least approximately 45° counterclockwise. The recess has a round profile with a diameter matched to the largest diameter of the gymnastic bar. In addition to the recess on the inner flank of the guide rail, there is also a suitable rounding on its outer flank, allowing the rung to be rotated 45° counterclockwise into the clamping position.

[0013] Further applications for the gymnastic and sports equipment according to the invention are conceivable if fixings are anchored in the support elements, which protrude from the profile of the support bar on their inner side or encompass a component protruding from the profile. The construction thus features a locking element, for which threaded bushings are located at regular intervals on the back of the support elements. From the front, brackets and similar components can then be inserted into the threaded bushing through a screw-in opening. This offers several application possibilities. For example, the wooden rungs can be secured against jumping out of the guide by means of a rubber ring that is placed around the rung and the aforementioned bracket. Furthermore, adapters or extensions that allow for additional gripping or holding options can be installed there.For example, a support bracket could be designed so that a crossbar can be fixed in front of the door frame instead of inside it. Furthermore, brackets for the crossbars can be attached there.

[0014] If the top of the tension block has a covering that improves the frictional connection to the door or wall opening, additional stability is ensured. Such a covering, for example made of rubber, can be fixed to the top of the block with an adhesive. Besides this additional protection against slippage, the covering ensures that the support struts can be removed from the door frame without damage.

[0015] Another advantageous embodiment of the invention provides that the support strut has a stop corresponding to the door or wall opening, which serves to support the support strut in a transverse direction to the longitudinal axis of the support strut and preferably extends over the length of the support strut. Such a stop serves as an additional installation aid and, moreover, provides additional stability during subsequent operation. for the support struts and thus the entire gymnastic and sports equipment. With the stop, the support strut sits, so to speak, in front of the door frame, thus ensuring that the entire construction is sufficiently stable even under comparatively high lateral forces.

[0016] As an additional bracing measure for the gymnastic and sports equipment according to the invention, the support strut is provided with a clamping bracket, which serves to brace the support strut in a transverse direction to the longitudinal axis of the support strut. Such a clamping or adjusting bracket can rest in the frame rebate, on the frame lining, or on the masonry and serve to additionally absorb and transmit a unilaterally directed transverse force, which counteracts the transverse force that the stop is designed to absorb.

[0017] This installation can be significantly improved by having the clamping angle on the side of the support strut opposite the stop have a web that is longer than the depth of the support strut and is connected to the support strut by an additional fastening device.

[0018] The invention is particularly distinguished by the fact that it provides a gymnastic and sports apparatus for mounting in a door or wall opening, which is easy and secure to install and also allows for safe operation with additional athletic exercises. A guide track in the opposing support struts proves advantageous for inserting gymnastic bars (rungs), especially when this guide track corresponds to the smallest diameter of a door bar with an oval cross-section. The gymnastic apparatus thus forms a substructure without the need for a direct, force-fit connection between the cross strut and the door frame.

[0019] This door rod has two insertion positions in the guide rail: a first in a rear, lower chamber of the guide rail, which extends downwards parallel to the support struts, and a second in which the rod can be wedged in the transition area between the two chambers of the guide rail. Installation of the support struts is also significantly simplified if a clamping block, connected to the top of the support strut, is clamped to the underside of the frame. In addition, the support strut has a stop for contact with the door or wall opening, which preferably extends over the entire length of the support strut and provides the overall structure with additional lateral support. A clamping bracket can perform this function in the opposite direction.

[0020] Further details and advantages of the invention will become apparent from the following description of the accompanying drawing, in which a preferred embodiment is shown with the necessary details and components. The drawing shows: Fig. 1 a piece of gymnastic and sports equipment installed in a doorway, Fig. 2 a leadership backdrop, Fig. 3 a guide backdrop with inserted gymnastic bar, Fig. 4 a support strut with fixing, Fig. 5 a support strut with tension block, Fig. 6 an installed support strut in cross-section, Fig. 7 the support strut to Fig. 6 with an additional bracket and Fig. 8 an installed gymnastic bar with additional support.

[0021] Fig. Figure 1 shows a gymnastic and sports apparatus 1 in the form of support struts 2, 3 with the tensioning blocks 23 and 24 at the upper ends 25, 26 of the support struts 2, 3. On the inside 4 of the support strut 2 are four exemplary receptacles labeled with reference numbers 5 - 8, two receptacles 5, 7 with a cam and two round receptacles 6, 8. A gymnastic bar 9 is inserted into the cam 5.

[0022] The management framework 11 is of particular concern to the Fig. 2 and Fig. 3. The guide track 11 initially extends in the area of ​​a first, front, upper chamber 36, into which the gymnastic bar 9 is inserted transversely to the longitudinal axis 15 of the support strut 2, as shown. Fig. Figure 2 illustrates this. The guide track 11 includes a second, rear, lower chamber 37, into which the rung 9 then slides parallel to the longitudinal axis 15 of the support strut 2. Reference numeral 14 indicates an angle, which may deviate from a right angle. Additionally, the bulge on the inner flank 17 of the guide track 11 is designated 16. Above this guide track 11 is the receptacle 6, and above that, a threaded bushing 27 as part of a bracket not shown here.

[0023] Fig. Figure 3a illustrates the possibilities for inserting the gymnastic bar 9 into the guide track 11, for which a gymnastic bar 9 is shown in two positions. First, the rung 9 is inserted into the front chamber 36 before, after a slight rotation in the direction of arrow 38, it slides into the lower position marked 9' in the rear chamber 37, where it is held securely against rotation. This is also due to the fact that the width of the guide track 11, i.e., the distance between the inner flank 17 and the outer flank 13 of the guide track 11, corresponds to the smaller diameter of the gymnastic bar 9 with its oval cross-section, which otherwise could not be inserted into the guide track 11 at all.

[0024] In an intermediate or clamping position in the area of ​​the transition between the two chambers 36 and 37 of the guide cam 11, Fig. 3b the gymnastic bar 9. This was fixed, in the area of ​​the bend 14, by a rotation of approximately 45° counterclockwise between the bulge 16 on the inner flank 17 on the one hand and the outer flank 13 on the other, symbolized by arrows 39 and 40. The gymnastic bar (rung) 9 is thus wedged there in a rotation-proof manner.

[0025] Fig. Figure 4 shows a cross-section of a support strut 2 with the stop 30. Particular attention in this illustration is paid to the fixing 18 with the threaded insert 59 on the outer side 60 of the support profile 2. The components are fixed in the threaded bushing 34 from the inner side 19 of the support profile 2 by means of a hand-operated screw 58 through a through-hole in the profile. Various fastening options can then be implemented in the area of ​​the handle 20 on the inner side 19 of the support strut 2.

[0026] Fig. Figure 5 illustrates in particular the function of a clamping block 23, which serves for the detachable fastening, height adjustment, and precise positioning of the support strut 2 in the wall or door opening. A pair of fastening rods 21, 22 are used to adjust the clamping block 23 at the upper end 25 of the support strut 2. These are securely screwed in place by means of threaded inserts 51, 52. Corresponding to the threaded rods 49, 50 are guide shafts 53, 54, which are provided in the support element 2. The guide shafts 53, 54 are slightly larger than the outer diameter of the threaded rods 49, 50. To adjust the height of the clamping block 23, adjusting nuts 47, 48 positioned between the clamping block 23 and the upper end 25 of the support element 2 are used. On the top 29 of the clamping block 23 there is a self-adhesive covering 28 with a rough surface 61, which provides additional frictional contact with the wall or door opening.The coating 28, in the form of a rubber underlay, is applied over the entire surface in order to increase its anti-slip effect and also to prevent abrasion damage to door frames.

[0027] The stop, which should extend as far as possible over the entire length of a support strut 2 and project at right angles, is in Fig. Figure 6 illustrates how this serves to absorb and transmit shear forces, as illustrated by arrow 43. In the installed state, this stop 30 runs parallel to the door or wall opening and is located according to the diagram. Fig. 6 in the frame rebate 42 or possibly also on the frame cladding 44.

[0028] A clamping or adjusting angle 31, fixed by a screw connection, is at the center of Fig. 7. Thanks to the elongated hole 35, this is easily adaptable to the given conditions and serves to receive and transmit a unilaterally directed transverse force, symbolized by the arrow 46, from the direction of the door or wall opening, in addition to the stop 30. The elongated hole 35 allows almost any desired distance to be bridged, thus enabling highly variable fastening. This is shown in Fig. 7 A clamping angle 31 with two webs 33, 62 of different lengths. The shorter web 33 on the side 32 of the support strut 2 opposite the stop 30 is longer than the depth of the support strut 2 and rests directly on the frame cladding 56, which, together with the frame body 55 and frame cladding 44, forms the frame for the wall 45. In the case of a lateral shear force acting from one side from the direction of the door or wall opening, symbolized by the arrow 46, this force is absorbed by the short web 33 and transferred either directly or via the door frame 55 to the masonry 45.

[0029] Finally, it shows Fig. 8 an additional form of fastening, here formed by a band 41 for connecting the gymnastic bar 9 to the fixing 18 in the receptacle 7. The band 41 additionally serves to prevent the gymnastic bar 9 from slipping out of the receptacle.
