Abstract

A goal frame for soccer or similar games comprising hollow bar and post sections, mitered at the corners and rigidly joined to each other by internally located corner pieces. Joined to each corner piece is a supporting tube which projects horizontally from the bar and post toward the back of the goal. The supporting tube is braced against the bar and post sections by braces. The backside of the goal frame has a continuous slot which retains a profiled strip with hooks and eyes for supporting the net. The post sections are supported in ground sockets having annular constrictions.

Description

The invention relates to a goal frame composed of light metal profiles for foot or handball games, in which the slatted profile and post profiles are formed by miter-cut hollow profiles, which are arranged in their cavities in the area of the miters and are held together by corner angles formed from double-T profiles are connected and in which holding devices for supporting the network are fastened in the corner region of the superimposed profiles, and in which a continuous groove is also let in in the longitudinal direction of the walls of the profiles facing the back of the gate, in which hooks are arranged at a distance from one another for fastening the network , and in which the ends of the post profiles can be inserted into ground sleeves made of the same material.

Goal frames of the type mentioned are known, e.g. DE-U-8 024109; DE-U-7 914 391. Here, the corner brackets are connected to the posts and the slat after insertion into their cavities by means of several hexagon socket screws. For this purpose, the lath and post profiles have countersunk holes and the corner bracket has threaded holes. However, it has been shown that attaching the screws takes a lot of time and effort, since the threaded holes are no longer visible after the profile corners have been pushed together and must be sought. In addition, the screws can also be easily lost. In addition, the stability of the corner connection fixed in the known manner is not very great.

In the known constructions, a net bracket with a strut is used as the holding device for the net, the assembly of which is also very complex since these have to be fastened to the main profiles by means of several screws and washers in a specially designed guide rail.

In the known goal frames, a continuous C-groove is embedded in the slat and post profiles as a guide rail, which serves to accommodate locknuts into which individual hooks are screwed to hold the net. In addition to the fact that this groove weakens the goal frame profiles, since this must be very deep, the attachment of the individual net hooks is very time-consuming and complicated. Approx. 70-80 hooks and sliding blocks must be installed and evenly distributed over the entire circumference of the goal frame. In addition, the hooks can only be arranged at a distance of approx. 300 mm, which causes the net to sag in many places.

In the known constructions, the hook openings are also in different directions after screwing them down, which is disadvantageous when the net is suspended and requires additional effort.

A further disadvantage is that the net hooks fastened in this way project beyond the contour of the profile frame. This can easily cause injury to the player.

For the purpose of setting up the gates, the post ends are inserted into sleeves, which are anchored in concrete foundations, so that the gates can be removed from the ground sleeves and removed at any time, especially in winter. However, it has been shown here that grains of sand and small stones or the like quickly settle between the walls of the inserted post ends and the inner walls of the sleeves, which block a lifting out again. This is because the post ends are received very tightly in the sleeves so that the frame is held securely in the upright position. This slight play also has the disadvantage that the two post ends must always be moved evenly and vertically when setting up or dismantling the goal in order to prevent them from jamming in the sleeves, which is, however, extremely difficult to achieve. After the gate has been set up, it is usually hardly possible to take it out later.

The object of the invention is to provide a goal frame that is easy to assemble and disassemble. The goal frame should also have a particularly high stability and should be designed so that any risk of accidents is excluded.

This object is achieved according to the invention in that, at right angles to the web surface of the double-T profiles cut to miter and welded to one another, the corner brackets, in each case on the miter center thereof, a support tube for supporting the network or a short pipe socket is welded, which or which by one of the Lath and post profiles are pushed through after opening on the corner bracket, so that it protrudes towards the back of the gate and the free end of which is supported by pairs of struts in the form of tubular hollow profiles on the lath and post profiles, whereby the struts are screwed to the end at one end by means of a screw bolt arranged transversely to the support tube or pipe socket, while at their other end they have ends bent at right angles to the slat and post profiles, which ends in mutually corresponding openings in the slat or Post profile and Ec kwinkel inserted and held in the direction of the mitres of the slat and post profile in the exercise of clamping forces.

The corner connection of the door frame with support tube or pipe socket and struts designed according to the invention considerably simplifies and accelerates the assembly and disassembly of the same. To secure the corner connection, only a single screw is required, namely that for connecting the a strut end with the support tube or the pipe socket. This screw is easy to assemble. In addition, the support tube advantageously also provides support for the network.

Furthermore, the corner connection according to the invention has the advantage that not only is the support tube or the pipe socket securely supported on all sides, the angularity of the same to the goal frame and the stability of the corner connection is maintained, but moreover causes a particularly good stiffening of the entire goal frame . Furthermore, the leverage effect of the stiffening struts means that the lath and post profiles are held together with great force at the miter edges in such a way that no joints gap.

It is also advantageous that the support tube according to the invention is also suitable for attaching a further long, downwardly bent and support bracket which is supported on the ground, in such a way that a goal for Bundesliga games can be produced in a simple and effortless manner.

In a further advantageous embodiment of the invention, a groove running through the entire length of the slat and post profiles is embedded in the walls facing the back of the gate, which is covered by a profile strip which is convex to the outside and into which hooks and eyes are punched to hold the net edge , such that they are integrated into the outer wall of the profile strip.

The profile strip designed according to the invention with the integrated hooks is inserted and locked in the factory in the circumferential groove on the slat and post profile, as a result of which assembly work when assembling the door is no longer necessary.

There is no need to thread a large number of locknuts with net hooks into the groove on the goal frame, which took a lot of time and effort. The elimination of the lock nuts also has the advantage of simplifying the profile cross section of the receiving groove integrated in the wall of the goal frame profiles (elimination of the C profile of the groove by elimination of the C profile of the same and the lower groove depth), which leads to greater stability of the Contributes profiles.

The hooks integrated into the outer contour of the goal frame according to the invention mean that The advantage is that there is no risk of injury because there are no more hooks protruding from the groove in the goal frame, as was previously the case.

In a further advantageous embodiment of the invention, the struts are provided at one end with holding shells which lie opposite one another on the support tube or pipe socket, and holes are arranged correspondingly to one another in the walls of the holding shells and support pipe or pipe socket, through which the screw bolt is inserted in each case is.

This ensures that the support tube or the pipe socket is securely supported and held in all directions, only a single screw bolt being required for fastening.

It is also advantageous that the struts at their ends bent at right angles to the slat or post profile each have locking bolts arranged in the strut transverse direction with ends protruding over the outer tube walls of the struts, which ends after insertion through correspondingly shaped recesses in the respective corner angle leg and rotation by 90 ° in End position are held on the web walls of the same.

According to a further advantageous embodiment of the invention, the struts can each have a transverse notch in the area of their penetration points through the corner angle legs, on their outer wall areas facing the corners of the goal frame, which hooks on the wall of the associated corner angle leg after inserting and mounting the struts.

Through this Both alternative measures advantageously prevent the struts from being lifted out.

According to a further advantageous embodiment of the invention, the struts which support the short pipe socket are shaped such that they each run parallel to the slat or post profiles. This alternative enables the advantageous corner connection according to the invention to be used in door designs without a device for supporting the network.

Advantageously, the profile strip for net suspension, seen in cross-section, has short legs bent at an angle inwards on its longitudinal edges, which engage in groove-shaped recesses formed by strips on the edges of the grooves after the profile strip has been inserted.

In this way, a secure hold of the profile strip in the receiving groove and its integration into the outer contour of the main profile is achieved without the need for complex profiling of the receiving groove. Both the bent legs of the profile strip and the groove-shaped recesses in the groove need only be of small dimensions, so that weakening of the profile is avoided.

It is also advantageous that the hooks are punched out in the transverse direction of the profile bar, each directed alternately in opposite directions, and that all hook eyelets are also arranged on the central axis of the profile bar.

The fact that the hooks point alternately in the opposite direction makes it more difficult for the net holding rope to be unhooked automatically.

The hook parts are easily accessible due to the fact that the profile strip, together with the hook and eye parts, is arched in a roof shape and the surface contour of the slat and post profiles is adapted Lich, which makes hanging the net much easier and eliminates the risk of accidents. It is also advantageous that, in the construction according to the invention, the hooks always point in one direction, namely in the transverse direction of the profile strip, so that the openings no longer have to be searched for when the net is attached.

The hooks are advantageously bent slightly at their ends towards the inside of the profile strip. This reliably prevents the net-holding rope from being unhooked automatically and at the same time further reduces the risk of accidents.

According to another embodiment of the invention, the hooks can be equipped at their ends with two mutually opposite retaining lugs pointing in the longitudinal direction of the profile strip. In this way, too, automatic unhooking of the net tether can be avoided.

Because all hook eyelets are arranged in the direction of the central longitudinal axis of the bar, the hanging cord for the net always runs in one direction, which also makes it very easy to hang up.

As a result of the advantageous embodiment of the profile strip according to the invention, the hooks are at a mutual distance of approximately 60 mm. This ensures that a good and exact fit of the net without sagging is guaranteed at every point of the goal frame.

According to a further advantageous embodiment of the invention, the base sleeves for receiving the ends of the post profiles are each closed at the bottom with a base plate and two mutually parallel, annular constrictions, namely just below the opening and just above the base plate, which follow on the outer wall of the post profile Insert tightly into the floor sleeves such that annular spaces are formed between the inner wall of the floor sleeves and the outer wall of the post profiles.

This configuration increases the clear opening dimension of the base sleeve in such a way that an annular space which is only interrupted by the constrictions is formed between the inside wall of the base sleeve and the outside wall of the inserted post end of the frame profile. This has the advantage that lifting of the post ends cannot be hindered by dirt particles, grains of sand or the like, since there is always sufficient play. Nevertheless, the linear support of the post ends by means of the constrictions ensures that the inserted goal frame fits well.

The constrictions spaced apart from one another furthermore provide the advantage of good guidance when inserting the post end. On the other hand, an easier removal of the same is guaranteed when the gate is dismantled. Due to the line-by-line mounting and the short protrusion of the post ends in the sleeve, based on the lower constriction, the post end has greater freedom of movement when being pulled out, so that this does not necessarily have to be uniform and vertical, as is required in the known sleeve designs.

The embodiment of the invention shown schematically in the drawings with the aid of a soccer goal consists of a goal frame composed of slat profile 1 and post profiles 2. Light metal hollow profiles of the same cross section are used as profiles, which are mitred at the corners and connected by corner brackets 3 arranged and held in their cavities in the form of miter cut and welded double-T profiles. Hollow box sections can also be used as corner brackets.

A support tube 4 is welded onto the miter center in the web area of the corner angles 3 formed from double-T profiles at right angles to the web surface. In the embodiment, not shown in the drawings, with corner angles formed from box hollow profiles, the end of the support tube 4 penetrates both walls of the profile and is welded to it at these points. In this way, a particularly great stability of the connection between the support tube and the corner bracket is achieved.

In the miter-cut slat and post profiles 1, 2, opposite recesses are arranged in the walls facing the back of the gate, also in the area of the miter center, which leave an opening 5 with the diameter of the support tube 4 after connecting the profiles. After inserting the corner bracket 3 with the welded support tube 4 into the cavities of the lath and post profile 1, 2 and plugging together, the support tube 4 protrudes from the opening 5 in a horizontal direction to the rear of the gate above.

The support tubes 4 are each supported by means of pairs of struts 6 in the form of hollow tube profiles on the lath profile 1 or the post profiles 2. The respective one ends 7 of the struts 6 are bent at an angle to the goal frame and are inserted through openings 8, 9 which correspond to one another in the slat and post profile walls and in the corner brackets 3 and are held at the corner bracket 3 by means of a locking bolt 10. The locking pin 10, which penetrates the struts 6 in the transverse direction, has short ends 11 projecting beyond the outer wall of the strut 6, which ends during assembly by corresponding, mutually corresponding openings 8, 9 in the slat or post profile 1, 2 and Corner angle 3 arranged recesses 12 are inserted. After rotating the struts 6 in the end position, the locking bolts 10 are held by the wall of the corner bracket 3.

Instead of a locking bolt 10, a notch not shown in the drawings can be arranged to hold the struts 6 in the region of the penetration point through the corner angle leg on the respective miter-facing tube outer wall of the strut 6, which notch is shown in the drawings and which can be assembled with the corner angle after mounting the strut 6 hooked.

The other ends of the struts 6 are provided with holding shells 13, which are arranged and shaped in such a way that, after the struts 6 have been mounted, they engage tightly around the end of the support tube 4. Corresponding bores 14 and 15 are arranged in the walls of the holding shells 13 and the support tube 4, through which a screw bolt 16 can be inserted transversely to the support tube 4, such that the whole is combined with the lock nut 17 to form a stable connection. In this way, the support tubes 4 serve once to support the network, but at the same time also to secure the corner connection of the goal frame according to the invention.

In the event that no support tube 4 is required for a network support, a short pipe socket 18 can be provided instead according to another embodiment of the invention (see FIG. 10), in which the struts 19 are shaped such that they are not inclined, but run parallel to the support or slat profile 2 or 1. The attachment takes place in the same way as with the struts 6.

In the walls of the slat and post profiles 1, 2 directed towards the rear of the goal frame, a groove 20 is inserted which extends over the entire length thereof and is covered by a profile strip 21 which is convexly curved outwards, into the hooks 22 and eyelets 23 for holding the Mesh edge are worked in by punching out the profile wall.

The profile strip 21 has, seen in cross section, short, bent legs 24 on its longitudinal edges, which, after the profile strip 21 has been inserted, engage in groove-shaped recesses 26 formed by strips 25 on the edges of the groove 20.

The hooks 22 of the profile strip 21 are arranged such that they point alternately in opposite directions in the transverse direction thereof. At the ends of the hooks 22 can be arranged in the longitudinal direction of the profile bar 21, oppositely directed retaining lugs 27 (Fig. 9). Or the hooks 22 have no retaining lugs and are slightly bent at their ends 33 towards the inside of the profile strip 21 (FIG. 7). The hooks 22 and eyes 23 are provided over the entire length of the profile strip 21 in the insertion grid of approximately 60 mm. In an advantageous further embodiment of the invention, the ends of the hooks 22 together with the retaining lugs 27 can also be bent inwards.

The entire goal frame is set up by inserting the ends of the two post profiles 2 into ground sleeves 28 anchored in the ground. Due to the particularly advantageous embodiment of the same, it is possible to remove the goal frame from the ground sleeves 28 again simply by lifting its post ends, even if the sleeves are contaminated by small stones or grains of sand.

Each base sleeve 28 has a base plate 29 and two annular constrictions 30 arranged parallel to one another, namely just below the opening 31 and just above the base plate 29. These rest on the post profile 2 and support it. In this way, two annular spaces of relatively large width are formed between the inner wall of the base sleeve 28 and the outer wall of the post profile, so that blocking by sand or small stones cannot occur when the post profile 2 is lifted out.

All of the individual and combinations disclosed in the description and / or the drawings Features are considered essential to the invention.
