Description

The invention relates to a holding system with a support element.A holding system of this type for shelves as a holding element is known from DE 20 2012 101 828 U1. In this holding system, shelves are pushed as holding elements laterally into a stand which forms the supporting element. On a complete longitudinal side of the shelves, an upwardly directed strip is arranged, which serves as a blocking element. The shelves can be pushed with the strip laterally into two support elements arranged next to one another, and the strip prevents the shelves from being pulled out of the support elements to the front as a blocking element. This results in a simple construction of a holding system consisting of support elements and holding elements.This already known holding system, however, has the disadvantage that the shelves serving as holding element must be very carefully inserted into the L-shaped groove of the supporting element in order not to tilt there. In particular, in the case of two support elements arranged side by side, it is difficult to insert the support element into both support elements. Furthermore, a variable design of the shelves is difficult, since they always have a ledge on the entire holding side.A similar construction is shown by the fastening element for cladding elements described in DE 92 10 602 U1.The object of the invention is therefore to further develop such a holding system in such a way that it can be mounted and disassembled more easily.This object is achieved in a generic holding system in that it has the features of claim 1. Advantageous refinements are the subject matter of the dependent claims.This makes it possible to make the blocking element smaller, so that the holding element with the blocking element can be inserted into the supporting element particularly easily. When the holding element is inserted in a positionally accurate manner, it can be pulled slightly forwards in the x direction with the locking element, wherein the locking element slides into the recess in which it is secured against lateral slipping on both sides in the z direction by the contact surfaces. The guide in the support element for the holding element can be designed to be so large that the holding element can be very easily inserted laterally into the support element. The loosely inserted holding element is only stabilized in that it slips somewhat out of the supporting element in the x-direction by pulling or by a load on the holding element until the blocking element lies in the recess in such a way that it is fixed on both sides in the z-direction and in the x-direction by contact surfaces.The specially formed recess for receiving the blocking element thus makes it possible to dimension the support element so small that it can easily be inserted into the guide in the holding element. The play of the retaining element in the support element is subsequently eliminated by loading the support element or by advancing the support element, since the blocking element of the retaining element slides into the recess and stabilizes the retaining system.For the function according to the invention, the blocking element can protrude upward or downward or upward and downward from the holding element in the y-direction. However, it is advantageous if the blocking element protrudes at least upward and the recess is arranged above the support element in the y direction, since a load then leads to a movement of the blocking element in the x direction.The support element has a groove for inserting the retaining element. This groove extends in the z-direction only as far as the recess in the support element. As a result, the stability of the supporting element is weakened to a lesser extent by the groove.A particularly large clearance between the support element and the holding element is achieved in that the partial region of the holding element is arranged in the support element such that there is a gap between the holding element and the support element in the x direction. This gap facilitates the insertion of the holding element into the supporting element and is preferably at least two millimeters wide in the x direction and preferably at least four millimeters wide. If the locking element is in its end position as a result of dislocation in the x direction, a free space corresponding to the dislocation of the locking element is produced between the supporting element and the holding element behind the holding element.A splint is arranged in the free space, which fills and can be removed from the free space. Such a splint can be arranged on one side or also on both sides of the holding element in the z-direction and extend into the free space. The splint prevents a rearward movement of the locking element out of the recess.In order to prevent the blocking element from slipping out and thus the possibility of removing the supporting element, the free space which arises between the supporting element and the wall and corresponds to the dislocation of the blocking element can be closed by a strip. This embodiment also prevents the removal of the support element from the holding element.A special embodiment of this strip provides that it is L-shaped. This ensures that the strip does not dissociate in the free space. The strip can also serve to close the entire free space behind the holding element as far as the supporting element.Preferably, the locking element is only a smaller element which prevents the retaining element from sliding out forwards. It is therefore proposed that the blocking element is narrower in the z direction than the holding element and preferably also narrower than the supporting element.An advantageous embodiment provides that the locking element is a pin. This pin can preferably be round or square in cross section and, for example, square or trapezoidal.Further uses are evident if the pin has a thread. This makes it possible to lengthen the pin and to lead it out of the supporting element in order then to be able to attach further elements, for example. The pin can also be mounted at any desired holding elements by means of a screw or plug connection at a defined position, which only have to have an extent in the y direction which is smaller than the insertion slot present on the supporting element.A simple construction of the support element is achieved in that the support element has an inner part over which a cover is placed in the y direction. An L-shaped slot in the tube then makes it possible to insert the retaining element into the supporting element. The cover in turn is then the limitation of the dislocation of the blocking element in the x direction.The described holding system can be reduced in the simplest form to a very narrow support element in the y-direction, into which support element the holding element with locking element is introduced laterally.Depending on the embodiment, the support element can have one or more insertion grooves for the holding element, so that one or more holding elements can be mounted. It is also advantageous if a holding element is introduced simultaneously into two supporting elements if multiple anchoring is desired.The object on which the invention is based is also achieved by a method having the features of patent claim 13.Different embodiments provide that the holding element is either pushed laterally straight (in the z direction) into the tag element or pivoted laterally into the supporting element in an arc line in the plane of the x direction and the z direction.Advantageous embodiments are illustrated in the drawing and are explained in more detail below. It shows:, FIG. 1 shows a perspective view of a supporting element and a holding element inserted therein, FIG. 2 shows a section through the support element and the retaining element along the line AA in FIG. 1, FIG. 3 shows a section through the support element and the retaining element along the line BB in FIG. 1, FIG. 4 shows a section in the plane of the section of FIG. 2 with a rectangular support element made of an inner part over which a cover is placed, FIG. 5 shows a perspective view of a support element and a retaining element inserted therein, similar to FIG. 1, with a splint between support element and retaining element, FIG. 6 shows a section similar to FIG. 2 with a round holding element, FIG. 7 shows a section through the support element and the retaining element in FIG. 5 in the plane of the blocking element and the splint, and FIG. 8 shows a perspective view of a 1-shaped strip in the free space.The holding system shown in FIG. 1 consists of a support element 1 which is perpendicular in the y-axis and a holding element 2 which extends in the x- and z-axes. Since the holding element 2 has an upwardly projecting blocking element 3, the holding element cannot be inserted from the front in the x direction, but only laterally in the z direction. For this purpose, the groove is L-shaped so that the locking element 3 can be inserted into the support element.In the figures, functionally similar parts are denoted by the same reference numerals for simplicity.In the exemplary embodiments, an enlargement of the groove in the x direction is provided approximately in the middle of the support element 1 above the holding element 2, said groove forming a recess which has a contact surface on both sides in the z direction and makes it possible to accommodate the blocking element 3. It is therefore possible to insert the holding element into the groove of the supporting element in the z-direction and then to slightly pull the holding element in the x-direction, so that the locking element lies in the recess.If an attempt is now made to displace the retaining element in the z direction, the blocking element abuts one of the abutment surfaces which prevent displacement of the retaining element in the z direction.However, the holding element 2 can still be removed from the support element 1 by moving the holding element somewhat back into the groove of the support element in the x direction, wherein the blocking element 3 is pushed out of the recess and is displaceable again in the z direction in order to pull the holding element 2 out of the support element 1 in the z direction.The holding element 2 can thus be slid laterally into the supporting element and the blocking element 3 secures the holding element 2 against being pulled out of the groove of the supporting element 1. a pressure from above on the holding element 2 when the holding element 2 is loaded leads to a tilting of the partial region of the holding element 2 inserted into the groove of the supporting element and stabilizes the holding system.FIGS. 2 and 3 show different views of the locking element accommodated in the recess. This locking element is shown as an upwardly projecting element. It can also project downward in a corresponding manner and slide into a recess arranged below the retaining element in the supporting element.FIG. 4 shows a further exemplary embodiment, in which the support element 1 has an inner part over which a cover 5 is placed. The groove in the support element 1 is provided in the inner part, so that the support element 2 can be pushed in laterally in the z direction and the blocking element, when the support element 2 is pulled in the x direction, strikes the cover and, when the movement in the z direction is attempted, strikes contact surfaces on the inner part of the support element 1.As long as removal of the holding element from the supporting element is not intended, a splint 4 can be pushed between the holding element 2 and the supporting element 1 in order to prevent displacement of the holding element 2, in particular in the x direction, after the holding element 2 has been inserted into the supporting element 1. This splint 4 can be loosely inserted in order to prevent the locking element 3 from sliding out of the recess. However, it can also be tilted in the groove in such a way that it no longer has any play and prevents any movement of the retaining element relative to the supporting element.The function of such a splint is shown in FIGS. 5, 6 to 7. FIG. 5 shows a very simple embodiment of a short rod of square cross section as splint 4. FIG. 6 shows, using the example of a round holding element 2 and a round supporting element 1, a longer splint 4 which reaches into the region of the recess, wherein this embodiment allows a rotation of holding element 2 and locking element 3. FIG. 7 shows a section through the exemplary embodiments shown in FIGS. 5 and 6.A displacement of the holding element in the x direction can also be prevented by a strip 6 preventing the holding element from being able to move back into the free space in the z direction. An embodiment of a strip of L-shaped cross-section is shown in FIG. 8.Moreover, the groove in the support element does not have to extend from one side to the opposite side of the support element, as shown in the figures. For inserting the holding element with the blocking element 3, it is sufficient if the groove extends so far into the supporting element that the blocking element can slide into the recess.
