in the drawings , the reference sign 1 refers to a guide rail and the reference sign 2 refers a grid side part , or grid - like side part . the side part 2 includes several horizontally extending bars 3 that are each provided with bent end regions 3 a and 3 b . the bent end regions 3 a are , for example , at each front end , and the end regions 3 b are , for example , at each rear end of the bars 3 . the underside of the guide rail 1 is provided with a quick fastening device . the quick fastening device includes two mounting elements 4 and 5 that are fixed in the bent end regions 3 a , 3 b of the guide rail 1 . the mounting element 4 is located at the front end of the guide rail 1 and the mounting element 5 is located at the rear end . the front mounting element 4 , as shown in fig6 and 7 , is provided with two bracket - like mounting sections 4 a and 4 b . these mounting sections 4 a and 4 b are at an angle to each other , which corresponds to the number of degrees of the angle of the front , end region 3 a relative to horizontal bar 3 . to this extent , the bracket - like mounting sections 4 a and 4 b can , for example , be perpendicular to each other . however , it is within the scope of the present disclosure for the mounting sections 4 a and 4 b to be arranged at an angle of more than 90 ° to each other . in the assembled state , the mounting section 4 a grips bar 3 in its longitudinally extending region and the mounting section 4 b grips the bent , front end 3 a of a bar 3 , so that the mounting element 4 can , for example , be fastened in a tilt - proof manner relative to only one bar 3 . the fixing of the guide rail 1 in the pull - out direction takes place at a front vertical bar 6 of the grid - like side part 2 by a stop 400 that engages behind the vertical bar 6 . the stop 400 is arranged adjacent to the mounting section 4 b at an upper leg 41 . due to the adjacent arrangement of the stop 400 and the mounting section 4 b , the fixing of the guide rail 1 takes place in the pull - out direction and also in a direction contrary to the pull - out direction without having to take into account , in this regard , the spacing tolerances to a rear vertical bar 7 . the mounting section 4 a is limited on its underside by a lower leg 40 and an upper leg 41 . a distance between these two legs 40 and 41 relative to each other corresponds , for example , to a diameter of bar 3 . at the lower leg 40 , which engages bar 3 from below in an assembled state , there is a resilient catch lug 42 that extends in an upward direction towards the upper leg 41 and protrudes with its upper , free end 43 into an aperture 44 of the upper leg 41 , as shown in fig7 and 9 . fig9 represents a situation when the guide rail 1 is mounted to the bar 3 , for example , mounting element 4 is slid onto the bar 3 until it reaches its intended position of use . fig9 illustrates how the resilient catch lug 42 engages behind the bar 3 , so that it is only then possible to release the mounting element 4 from the bar 3 when , to begin with , the catch lug 42 is pressed down manually in the direction of the arrow a , as shown in fig9 , which is possible without further ado by pressing an operating section 45 . if the force that is directed downwards and onto the operation section 45 is removed again , the resilient catch lug 42 moves back into its position in accordance with that shown in fig6 , 7 and 9 . when the mounting element 4 is slid onto bar 3 , the catch lug 42 , via a lead - in chamfer 46 , is automatically pushed under and across the bar 3 until the catch lug 42 can again move freely upwards due to the resilient restoring forces . in the assembled state as shown in fig9 , it is shown that the side edge 47 of the catch lug 42 facing the bar 3 extends upwards and is inclined towards the bar 3 . it has already been mentioned that the free end 43 of the catch lug 42 protrudes into an aperture 44 of the upper leg 41 . fig9 shows again that the upper , front side free end 43 of the catch lug 42 is formed in a rounded fashion and with this rounded portion it lies against the underside of the guide rail 1 when corresponding high restoring forces are provided . the catch lug 42 is then pushed up if the mounting element 4 is inadvertently moved in a horizontal direction away from the bar 3 , because then the upwardly extending and inclined towards the bar 3 side edge 47 of the catch lug 42 lies against the bar 3 and the corresponding horizontal forces effect a raising of the catch lug 42 . a deflection of the catch lug 42 in a horizontal direction is additionally prevented by the safeguard of the end 43 form - fitting in the aperture 44 . in addition , in order to assist the form - fitting safeguard , the side of the end 43 facing away from the bar 3 can , for example , be steeper or even vertical ( see , for example , fig9 ). an inadvertent release is , according to the present disclosure , therefore , safely prevented also when high forces are applied . as shown in fig6 and 7 , the upper leg 41 has a bead 48 embossed downwards towards the bar 3 . the embossing of this bead 48 and its position are thus selected so that sliding the mounting element 4 onto the bar 3 requires a certain amount of force in order to slide the bead 48 over and away from the bar 3 during a simultaneous slight lowering of the upper leg 41 until the bead 48 engages in a position behind the bar 3 . this bead 48 indicates to the user during a potential assembly , that the mounting element 4 has assumed its designated position . that is because the user is sensitive to the different exertion forces involved . in addition , and aided by the springing back of the lower leg 40 into a relaxed position , the “ jumping over ” of the bead 48 over the bar 3 emits a sound that the user hears and can consider it to be a further indication of proper assembly . in order to facilitate the placement of the mounting element 4 , for the purpose of sliding it sideways onto a bar 3 , the upper leg 41 is provided with a bulge 49 extending in the direction of the bar 3 . the bulge 49 gives the user an easy orientation for the correct placement of the mounting element 4 in respect to the bar 3 to be engaged . the orientation guidance for the location and for mounting position of mounting element 4 relative to bar 3 , as described above in association with the bead 48 , for placing the mounting element 4 onto a bar 3 , can within the scope of the present disclosure , be implemented by a mounting element 4 ′, according to an embodiment of the present disclosure , as depicted in fig1 . the bead 48 is replaced by an open embossed feature 48 a directed downwards and into whose opening area the upper , front end 43 of the catch lug 42 can , for example , engage and whose outer margin area , like the bead 48 , must be pushed over and away from bar 4 in order to be able to bring the mounting element 4 ′ into its designated mounting position . also , a movement over the embossed feature 48 a results in the user receiving the previously noted orientation guidance for the proper location and / or mounting position of the mounting element 4 relative to the bar 3 . furthermore , with a low material thickness of the leg 41 , the form - fitted safeguard of the end 43 in the embossed feature 48 a is improved . the rear mounting element 5 , as can be seen in fig3 and 4 , is provided with a bracket - like mounting section 5 a that , in the assembled state , engages around bar 3 in its longitudinally extending area . this bracket - like mounting section 5 a is limited by a lower leg 50 and an upper leg 51 , wherein the distance of these two legs 50 and 51 between each other corresponds , in turn , to the thickness of the bar 3 . in addition , at the rear end region of the guide rail 1 , the mounting element 5 is equipped with a support lug 52 that , in the assembled state as depicted in fig3 , engages beneath the rear , bent end region 3 b of bar 3 . this support lug 52 is bent or angled downwards from the area of the upper leg 51 of the mounting element 5 and is located on the same plane as the lower leg 50 of the bracket - like mounting section 5 a . as the support lug 52 only engages beneath the end region 3 b , the distance tolerances between the vertical bars 6 and 7 are balanced out . in angled areas of the upper leg 51 , an adjoining downwardly directed web 53 , and the support lug 52 adjoined thereto , beads 54 are embossed that lead to a stiffening of the mounting element 5 in those angled areas . the installation of guide rail 1 , with the mounting elements 4 and 5 comprising the quick fastening device , to bar 3 of side grid 2 and starting from a position according to fig2 , is carried out as follows . to start with , the rear mounting element 5 is set sideways at bar 3 and then , for the moment , is pushed so far to the rear until the web 53 of the rear mounting element 5 strikes the rear , bent end 3 b of bar 3 . after that , the guide rail 1 with the front mounting element 4 is pivoted in a horizontal movement onto bar 3 from a starting position , as follows from fig8 . in the course of this pivoting , the front mounting element 4 , in a manner as specified above , is likewise pushed onto the longitudinally extending region of the bar 3 in the same way as onto the front , bent end 3 a of the same bar 3 . self - locking then takes place , as was described above . in the case of a required disassembly , the catch lug 42 is , to start with , pivoted away and downwards from the plane of the bar 3 . then , first , the guide rail 1 is pulled off the bar 3 in a horizontal pivoting movement , resulting in a position according to fig8 . the , second , the guide rail 1 can be removed completely from the bar 3 by pulling in the pull - out direction , and then taken away , for example , for cleaning purposes . the mounting elements 4 and 5 , may , according to the present disclosure , be formed in one piece and may , according the present disclosure , be made either of metal or of plastic material . although the present disclosure has been described and illustrated in detail , it is to be clearly understood that this is done by way of illustration and example only and is not to be taken by way of limitation . the scope of the present disclosure is to be limited only by the terms of the appended claims .
