Description

The present invention relates to a method for mounting a push element and a kit for slidably supporting a push element with a first and a second pull-out guide, which can be mounted on opposite side walls, and a preassembled device for synchronizing the movement of the movable rails of the two pull-out guides with a cable pull . The side walls are preferably the side walls of furniture or household appliances.

The DE 10 2013 113 672 A1 discloses a pull-out system in which two pull-out guides can be mounted on opposite side walls of a piece of furniture, the movable rails of the pull-out guides being coupled to one another via a device for synchronization. The device for synchronization comprises deflection rollers on a central rail of the pull-out guide and holders to fix a cable on the stationary guide rail and the movable running rail. This device for synchronization has proven itself, however, the assembly is relatively complex, since a holder with deflection rollers is mounted in the rear area of the central rail by means of screws. In addition, a locking element must be mounted on a tensioning device for tensioning the cable, which is inserted into grooves on a tensioning sleeve of a housing. The problem here is that insertion of the locking element is only possible when the grooves are aligned, which is difficult especially in poor lighting conditions. In addition, the locking element can be removed from the tensioning device and lost. The assembly of the cable with the individual cable sections is also comparatively complex, since each cable section is installed separately.

It is therefore an object of the present invention to provide a method for assembling a thrust element and a kit for the displaceable mounting of a thrust element, which enable assembly in a simple manner and enable efficient transport.

This object is achieved with a method with the features of claim 1 and a kit with the features of claim 6.

In the method according to the invention, the two pull-out guides are first fixed on opposite sides and then a device for synchronizing the movement of the movable rails of the two pull-out guides is installed. In this case, a holder with at least one deflecting element is attached or snapped onto each pull-out guide and a cable is placed around a deflecting roller that is already pre-assembled on the pull-out guide. Then at least one rail of each pull-out guide is also coupled to the cable pull via a connecting device and the tension of the cable pull is adjusted via a device for adjusting the cable tension. The assembly can thus be carried out in a few steps, in particular without tools, since the holders are attached or snapped on with the at least one deflection element. In addition, the cable pull can also be placed around the deflection roller as a pre-assembled unit and attached or snapped onto the rail via a connecting device. This means that a pull-out system with two pull-out guides can be installed within a short period of time in order to then be able to fix a push element to the pull-out guides.

To adjust the tension of the cable, a slide is preferably provided on at least one deflection element, which is moved from an assembly position into the fixed position. With the slide, two clamping sleeves provided with several receptacles can preferably be fixed in different positions relative to a housing of the holder. This reduces the number of components, since two clamping sleeves can be fixed to the housing at the same time with the slide. For easy assembly, insertion bevels can be provided on the slide and / or the receptacles on the clamping sleeve, which facilitate guiding the slide into the receptacles.

The connecting device is preferably mounted in such a way that a holder is provided which is fixed to the stationary guide rail and to the movable running rail and into which a coupling element connected to two sections of the cable pull can be inserted, in particular by latching or clamping. Two ends of a cable can then be mounted on a rail at the same time via the coupling element.

In the kit according to the invention, the device for synchronizing the movement of the movable rails is mounted on the two pull-out guides without tools. The two brackets with the deflection elements will be according to the invention snapped or snapped onto a rear region of the middle rail. In addition, the rope tension can be adjusted via spring-loaded tensioning sleeves, preferably in one of the two holders. The clamping sleeves are then secured in the set position with a slide which can be inserted into a receptacle of a clamping sleeve in order to fix it to a housing of the holder in the desired position, two clamping sleeves being able to be fixed simultaneously via the slide. The kit can thus consist of three units, namely the two pull-out guides and the device for synchronizing the movement of the movable rails, the device being able to be assembled without tools using only a few assembly steps. The device for synchronization can captively secure a slide on the holder, which can only be moved between an assembly position with a displaceable clamping sleeve and a fixed position with a fixed clamping sleeve. In addition, a stop can be formed on the clamping sleeve in order to captively fix the clamping sleeve to the holder with the deflecting element.

A kit for the displaceable mounting of a push element comprises a first pull-out guide 1, which can be mounted on a first side wall of a furniture body or a household appliance, and a second pull-out guide 1, which can be mounted on an opposite side wall. Each pull-out guide 1 can be fixed on the side wall via mounting brackets 10. In order to synchronize a movement of the pull-out guides, a device 2 is provided which connects the two pull-out guides 1 to one another. The device 2 for synchronizing the movement of the movable rails comprises two holders 3, each with at least one, preferably two deflection elements, in particular two deflection rollers 2, a cable pull 4, which can be made from one or more cable pull sections, and coupling elements 5 around the cable pull 4 to couple to the pull-out guides 1. Between the two holders 3 there are also two sleeve-shaped envelopes 6 which are part of a device for tensioning the cable 4.

The in Figure 1A The kit shown thus consists essentially of three units, namely the two pull-out guides 1 and the device 2 for synchronizing the movement of the movable rails. The facility 2 is in Figure 2B shown in the assembled position, the assembly is done without tools.

In Figure 1B it is shown that the two holders 3 are fixed to a rear region of a central rail 8 of each pull-out guide 1. Each pull-out guide 1 has a stationary guide rail 7 which is fixed to the mounting brackets 10, a middle rail 8 and a running rail 9 on which a drawer element, such as a drawer, can be fixed. On the middle rail 8, a deflection roller 11 is also rotatably mounted in the front region, around which the cable 4 is guided. The cable 4 is coupled via a coupling element 5 to the stationary guide rail 7 and a further coupling element 5 to the running rail 9. The cable 4 is circumferential and is guided by the coupling element 5 from the running rail 9 of a pull-out guide 1 via the two holders 3 to a coupling element 5 on the guide rail 7 of the other pull-out guide 1, from there via the deflection roller 11 to a coupling element 5 to be guided on the running track.

In Figure 1C it is shown that the kit can be arranged in a very space-saving manner for transport and thus a very inexpensive transport can be realized. This arrangement is in the pull-out system DE 10 2013 113 672 A1 not possible because the synchronization device is connected to the pull-out guide at the factory before transport.

In the Figures 2A and 2 B the assembly of a holder 3 is shown, which is mounted on the central rail 8. For this purpose, an abutment web 30 of a housing with two protruding hooks 31 and 32 is positioned at openings 33 and 34 of the central rail 8, the rear hook 32 first being inserted into the opening 34 and then the front hook 31 being inserted into the opening 33. The hooks 31 are designed as locking hooks and thus allow the holder 3 to be swiveled in and locked onto the central rail 8 without tools.

In the Figures 2A and 2 B a driver 12 is also shown, on which a coupling element 5 can be mounted. The driver 12 has a section mounted on the running rail 9 or a guide rail 7, from which two holding webs 13 and two receiving webs 14 protrude.

The driver 12 is in the Figures 3A and 3B shown enlarged. When the cylindrical coupling element 5 is assembled, it is inserted between the two receiving webs 14, so that the coupling element 5 is held between the two receiving webs 14 so that it cannot move in the axial direction. The receiving webs 14 each encompass a cylindrical mounting section 52, by means of which the cable 4 is fixed to the coupling element 5. The cylindrical mounting sections 52 are arranged in the longitudinal direction of the cable 4 between the two retaining webs 13 and thus also secured against movement in the longitudinal direction of the cable 4. The coupling element 5 can be plugged onto the receiving webs 14 from above, since the receiving webs 14 and holding webs 13 together with the driver 12 form a U-shaped receptacle. In the attached position, the receiving webs 14 grip around the cylindrical mounting sections 52, as shown in FIG. 3B.

In the Figures 4A and 4B a coupling element 5 is shown in detail which has a cylindrical sleeve 50 which has a plurality of latching elements 51 formed on both sides. A cylindrical mounting section 52, which is attached to the cable 40, and on which a groove 53 is formed, is inserted into the cylindrical sleeve 50 on both sides. The two mounting sections 52 engage with the groove 53 on the respective locking element 51 of the sleeve 50 in such a way that two sections of the cable 4 are connected to one another.

In Figure 5 the area of a deflection roller 11 is shown, which is arranged adjacent to a driver 12 on the guide rail 7. The pulley 11 is rotatably mounted on the middle rail 8 and deflects the cable 4 by about 180 °.

In Figure 6 the deflection roller 11 is shown in detail. The deflection roller 11 comprises a U-shaped receptacle 15 for the cable 4, wherein a side wall 16 towards the middle rail 8 is higher than an opposite side wall 17. The deflection roller 11 also has a bearing section 18 which is inserted into the middle rail 8.

In the Figures 7A and 7B the holder 3 is shown, on which a device for tensioning the cable 4 is provided. The holder 3 comprises a housing on which the contact web 30 with the two hooks 31 and 32 is integrally formed. Furthermore, a slide 20 is provided on the holder 3, which can be moved back and forth between two positions. The housing also has two sleeves 35 and 36, in each of which a clamping sleeve 40 is arranged, through which the cable 4 is carried out. In Figure 7B a section through the housing of the holder 3 is shown, and it can be seen that the slide 20 is arranged in an assembly position in which a sword 21 of the slide 20 is arranged at a distance from the clamping sleeves 40. The slide 20 comprises arms 22 with latching recesses 23 on opposite sides, each arm 22 having an inwardly projecting stop 24, which ensures that the slide 20 is captively attached to the holder 3.

In order to move the slide 20 from the assembly position with a movable clamping sleeve 40 into a fixed position, it is pushed into the holder 3, as shown in FIGS Figures 8A and 8B is shown. By pushing in, the two arms 22 are first unlocked from the first latching position and then pushed so far into the holder 3 that a second latching recess 23 on the arm 22 engages with a latching projection 38 on the holder 3. The sword 21 is also inserted on the slider 20 between the sleeves 35 and 36, a clamping sleeve 40 being fixed in each of the sleeves 35 and 36 via the sword 21.

In the Figures 9A and 9B a clamping sleeve 40 is shown as it is arranged in the sleeves 35 and 36 of the holder 3. The clamping sleeve 40 comprises an inner cavity in which the cable 4 is carried out and is inserted into an end piece 60 of the casing 6. A plurality of groove-shaped receptacles 41 are formed on the outside of the clamping sleeve 40 and are separated from one another by ribs 42. The recordings 41 are at least in the area of the sword 21 provided, but can also be provided at other circumferential locations. The clamping sleeve 40 is pretensioned away from the holder 3 by means of a spring 61, the maximum clamping path being predetermined by a stop 44 which projects from an arm 43 of the clamping sleeve 40. The stop 44 bears against the sleeve 35, as shown in FIG Figure 9B is shown, so that the clamping sleeve 40 can be pushed further into the holder 3 from this position, but can no longer be pulled out.

The tension of the cable 4 can be adjusted via the position of the clamping sleeve 40. The cable 4 is guided through the sheathing 6, with a movement of one of the two clamping sleeves 40, between which the sheathing 6 is arranged, the distance for the cable 4 in the sheathing 6 remaining constant, since this simply shortens the distance sags more. The cable 4 is tensioned when the clamping sleeve 40 is moved out of the holder 3, and relaxed when the clamping sleeve 40 is inserted into the holder 3 against the force of the spring 61. The tension of the cable 4 can be adjusted by the spring 61, and assembly tolerances can be compensated for.

In Figure 10 the slider 20 and the two clamping sleeves 40 are shown without the housing of the holder 3. The slider 20 encompasses the clamping sleeves 40 in a U-shaped manner with the arms 22, the clamping sleeves 40 being fixed via the central sword 21, which is inserted into a groove-shaped receptacle 41 of the clamping sleeves 40. The position of the two clamping sleeves 40 can thus be fixed with a single slide 20.

In the Figures 11A to 11D it is shown that the sword 21 is inserted into the receptacle 41 through insertion bevels 45 at tips, so that a movement into one of the receptacles 41 takes place regardless of the position of the clamping sleeve 40 relative to the sword 21. The sword 21 can then be inserted between two ribs 42 in the receptacle 41, which is arranged between two adjacent tips. The clamping sleeves 40 can be moved independently of one another in the assembly position, so that after the tension of the cable 4 has been set, the slide 20 is moved into the fixed position in order to fix the two clamping sleeves on the holder 3. During assembly, it is not necessary to ensure that the sword 21 is inserted into a receptacle 41, but rather through the insertion bevels 45 that it catches itself in the corresponding receptacle 41.

In Figure 12 a holder 3 is shown in the fixed position in which the slide 20 is inserted in order to fix the clamping sleeves 40 in the sleeves 35 and 36. In Figure 13A part of the housing of the holder 3 has been omitted, and it can be seen that the slider 20 secures the clamping sleeves 40 in the sleeves 35 and 36 against movement in the longitudinal direction of the cable 4. Furthermore, it can be seen that a deflection roller 37 is rotatably mounted on the holder 3 in order to deflect the cable 4 by approximately 90 °. In this case, two deflection rollers 37 are rotatably mounted within the holder 3, each deflecting a section of the cable 4. The deflection rollers 37 can be rotatable about an axis which is provided on the holder 3.

In Figure 14 A modified embodiment of a holder 3 'is shown, which is mounted on a central rail 8 of a pull-out guide 1. The holder 3 'comprises a mounting section for fixing to hooks 80 and 81 on the central rail 8, which has U-shaped receptacles 132, into each of which a hook 80 or 81 can be inserted. Otherwise, the holder 3 'is designed as in the previous exemplary embodiment and comprises a slide 20 for adjusting the cable tension.

As in the Figures 15A and 15B is shown, the holder 3 'is pushed onto the two hooks 80 and 81 of the middle rail 8, so that the hook 80 engages in the U-shaped receptacle 132 and secures a bottom section 130 between the hook 80 and the middle rail 8. In a similar way, the hook 81 engages in a U-shaped receptacle 133, so that the holder 3 ′ is fixed to the central rail 8 via the two hooks 80 and 81.

In Figure 16A A pull-out guide 1 is shown in each case, which has a central rail 8, each with a front opening 33 and a rear opening 34. The openings 33, 34 are each arranged at different locations on the central rail 8. As a result, the device 2 can be fixed at different positions on the central rail 8 of the pull-out guide, as a result of which an individual adaptation to the depth of the push elements and / or to the existing depth in the installation space, in particular in the household appliance or in the furniture body, can be carried out. In Figure 16B is analogous to a pull-out guide 1 with a front hook 80 and a rear hook 81, the hooks 80, 81 being arranged at different positions on the central rail 8. The positions of the openings 33, 34 or the hooks 80, 81 on the center rail 8 is purely exemplary and can vary. It is also possible the same to provide a plurality of openings 33, 34 or hooks 80, 81 on a central rail 8, which are then only partially occupied during assembly.
