Description

Method for assembling a push element and kit for the displaceable mounting of a push element, furniture and household appliance

The present invention relates to a method for assembling a push element and a kit for sliding support of a push element with a first and a second pull-out guide, which are mounted on opposite side walls, and a pre-assembled device for synchronizing the movement of the movable rails of the two pullout guides with a cable , The side walls are preferably the side walls of Möbelkorpen or household appliances.

DE 10 2013 1 13 672 A1 discloses a pull-out system in which two pull-out guides can be mounted on opposite side walls of a piece of furniture, wherein the movable rails of the pull-out guides are coupled to one another via a device for synchronization. The means for synchronization comprises deflection rollers on a middle rail of the pullout guide and holders to fix a cable to the stationary guide rail and the movable running rail. This device for synchronization has proven itself, but the installation is relatively complex, since a holder with pulleys in the rear of the center rail is mounted by means of screws. In addition, a locking element must be mounted on a clamping device for clamping the cable, which is inserted into grooves on a clamping sleeve of a housing. Here there is the problem that insertion of the locking element is only possible if the grooves are aligned, which is difficult especially in low light conditions. In addition, the locking element can be removed from the clamping device and lost. The assembly of the cable with the individual Seilzugabschnitten is also relatively complicated, since each Seilzugabschnitt is mounted separately.

It is therefore an object of the present invention to provide a method for mounting a thrust element and a kit for displaceable mounting of a thrust element, which allow easy installation and allow efficient transport.

This object is achieved by a method having the features of claim 1 and a kit having 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 mounted. In this case, a holder with at least one deflecting element is plugged or snapped on each pullout guide and placed a cable to a pulley already pre-assembled on the pullout guide. Then at least one rail of each pullout guide is coupled via a connecting device to the cable and the voltage of the cable is adjusted via a device for adjusting the cable tension. The assembly can thus take place in a few steps, in particular tool-free, since the holders are plugged or snapped with the at least one deflecting element. In addition, the cable can be placed as a preassembled unit to the pulley and attached to the rail via a connecting device or snapped. As a result, a pull-out system with two pull-out guides can be mounted within a short time in order to be able to fix a push element to the pull-out guides.

To adjust the tension of the cable, a slider is preferably provided on at least one deflecting element, which is moved from a mounting position to the fixed position. With the slider, two clamping sleeves provided with a plurality of receptacles can preferably be fixed in different positions relative to a housing of the holder. This reduces the number of components by simultaneously two clamping sleeves can be fixed to the housing with the slider. For easy mounting can be provided on the slide and / or the receptacles on the clamping sleeve insertion bevels, which facilitate a guide of the slide in the recordings. The connecting device is preferably mounted so that a fixed to the stationary guide rail and the movable track rail holder is provided, in each of which a coupling element connected to two sections of the cable is inserted, in particular by latching or clamping. Two ends of a cable pull can then be mounted on a rail simultaneously via the coupling element.

In the kit according to the invention, the installation of the device for synchronizing the movement of the movable rails without tools takes place at the two pull-out guides. The two holders with the deflection elements are preferably at a rear region of a rail, in particular the middle rail, plugged or snapped. In addition, adjustment of the cable tension via spring-loaded clamping sleeves can preferably be effected 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 to fix it to a housing of the holder in the desired position, wherein two clamping sleeves can be fixed simultaneously on the slide. The kit can thus consist of three units, namely the two pullout guides and the means for synchronizing the movement of the movable rails, the device can be mounted tool-free by only a few assembly steps. The device for synchronization can secure a slider captive on the holder, which is movable only between a mounting position with sliding clamping sleeve and a fixed position with a fixed clamping sleeve. In addition, a stop may be formed on the clamping sleeve to fix the clamping sleeve captive on the holder with the deflecting element.

The invention will be explained in more detail below with reference to an embodiment with reference to the accompanying drawings. Show it:

A kit for the displaceable mounting of a push element comprises a first pullout guide 1, which is mountable on a first side wall of a furniture body or a household appliance, and a second pullout guide 1, which is mountable on an opposite side wall. Each drawer slide 1 can be fixed on the side wall via mounting bracket 1 0. In order to synchronize a movement of the pullout guides, a device 2 is provided, which connects the two pullout guides 1 together. The device 2 for synchronizing the movement of the movable rails comprises two holders 3 each having at least one, preferably two deflecting elements, in particular two guide rollers 2, a cable 4, which may be made of one or more Seilzugabschnitten, and coupling elements 5 to the cable. 4 to couple to the pullout guides 1. Intermediate see the two holders 3 are still two sleeve-shaped sheaths 6 are arranged, which are part of a device for tensioning the cable 4.

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

In FIG. 1B, it is shown that the two holders 3 are fixed to a rear region of a middle rail 8 of each pull-out guide 1. Each pullout guide 1 in this case has a stationary guide rail 7, which is fixed to the mounting brackets 10, a middle rail 8 and a running rail 9 to which a push element, such as a drawer, can be fixed. On the center rail 8, a guide roller 1 1 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 with the stationary guide rail 7 and a further coupling element 5 with the running rail 9. The cable 4 is formed circumferentially and is guided by the coupling element 5 from the running rail 9 of a pullout guide 1 via the two holders 3 to a coupling element 5 on the guide rail 7 of the other pullout guide 1, from there over the pulley 1 1 again a coupling element 5 to be guided on the running rail.

In FIG. 1C, it is shown that the kit for transport can be arranged in a very space-saving manner and, as a result, a very cost-effective transport can be realized. This arrangement is not possible with the pull-out system of DE 1 0 2013 1 13372 A1, since the device for synchronization is already connected to the pullout guide at the factory prior to transport. FIGS. 2A and 2B show the mounting of a holder 3, which is mounted on the center rail 8. For this purpose, a contact bar 30 of a housing with two protruding hooks 31 and 32 is positioned at openings 33 and 34 of the center rail 8, wherein first the rear hook 32 is inserted into the opening 34 and then the front hook 31 in the opening 33. The hooks 31 are designed as latching hooks and thus enable a pivoting and locking of the holder 3 to the middle rail 8 without tools.

In Figures 2A and 2B, a driver 1 2 is further shown, on which a coupling element 5 can be mounted. The driver 1 2 has a mounted on the running rail 9 or a guide rail 7 section from which two holding webs 1 3 and two receiving webs 14 protrude.

The driver 12 is shown enlarged in Figures 3A and 3B. When mounting the cylindrical coupling element 5, this is inserted between the two receiving webs 14, so that the coupling element 5 is held immovably in the axial direction between the two receiving webs 14. The receiving webs 14 each encompass a cylindrical mounting portion 52, by means of which the cable 4 is fixed to the coupling element 5. The cylindrical mounting portions 52 are arranged in the longitudinal direction of the cable 4 between the two retaining webs 1 3 and thus also secured against movement in the longitudinal direction of the cable 4. The coupling element 5 can be plugged from above onto the receiving webs 14, since the receiving webs 14 and retaining webs 1 3 together with the driver 1 2 form a U-shaped receptacle. In the mounted position, the receiving webs 14 surround the cylindrical mounting portions 52, as shown in Figure 3B.

In FIGS. 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. In the cylindrical sleeve 50, a cylindrical mounting portion 52, which is fixed to the cable 40, inserted on both sides in each case, on which a groove 53 is formed. The two mounting portions 52 engage with the groove 53 on the respective latching element 51 of the sleeve 50 so that two portions of the cable 4 are interconnected.

FIG. 5 shows the region of a deflection roller 1 1, which is arranged adjacent to a driver 1 2 on the guide rail 7. The pulley 1 1 is rotatably mounted on the center rail 8 and deflects the cable 4 by about 1 80 °.

In Figure 6, the guide roller 1 1 is shown in detail. The deflection roller 1 1 comprises a U-shaped receptacle 1 5 for the cable 4, wherein a side wall 1 6 to the middle rail 8 towards higher than an opposite side wall 1 7. The deflection roller 1 1 further comprises a bearing portion 1 8, which is inserted in 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 abutment web 30 with the two hooks 31 and 32 is integrally formed. Further, a slider 20 is provided on the holder 3, which is movable back and forth between two positions. The housing further has two sleeves 35 and 36, in each of which a clamping sleeve 40 is arranged, through which the cable 4 is performed. In FIG. 7B, a section through the housing of the holder 3 is shown, and it can be seen that the slider 20 is arranged in a mounting position in which a blade 21 of the slider 20 is arranged at a distance from the clamping sleeves 40. The slider 20 comprises on opposite sides arms 22 with latching recesses 23, each arm 22 having an inwardly projecting stop 24, which ensures that the slider 20 is fixed captive on the holder 3.

In order to move the slider 20 from the mounting position with movable clamping sleeve 40 in a fixed position, it is inserted into the holder 3, as shown in Figures 8A and 8B. By inserting the two arms 22 are first unlocked from the first detent position and then pushed so far into the holder 3 that a second detent recess 23 on the arm 22 engages with a locking projection 38 on the holder 3. In this case, the sword 21 is inserted on the slider 20 between the sleeves 35 and 36, wherein via the sword 21 each have a clamping sleeve 40 is fixed in the sleeves 35 and 36.

FIGS. 9A and 9B show a clamping sleeve 40, 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 performed, and is inserted into an end piece 60 of the enclosure 6. On the outside of the clamping sleeve 40 a plurality of groove-shaped receptacles 41 are formed, which are separated by ribs 42 from each other. The recordings 41 are at least in the range of the sword 21 provided, but can also be provided at other circumferential locations. The clamping sleeve 40 is biased by a spring 61 away from the holder 3, wherein the maximum clamping path is determined by a stop 44 which protrudes on an arm 43 of the clamping sleeve 40. The stop 44 abuts against the sleeve 35, as shown in Figure 9 B, so that the

Although clamping sleeve 40 from this position can be further inserted into the holder 3, but not further pulled out.

The tension of the cable 4 can be adjusted via the position of the clamping sleeve 40. The cable 4 is guided by the sheath 6, wherein during a movement of the two clamping sleeves 40, between which the sheath 6 is arranged, the distance for the cable 4 in the casing 6 remains constant, as this simply a shortening of 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. By the spring 61, the tension of the cable 4 can be adjusted, and it can be compensated mounting tolerances. In Figure 10, the slider 20 and the two clamping sleeves 40 without the housing of the holder 3 are shown. The slider 20 engages with the arms 22, the clamping sleeves 40 U-shaped, with a fixation of the clamping sleeves 40 via the central sword 21, which is inserted into a groove-shaped receptacle 41 of the clamping sleeves 40. With a single slider 20 thus the position of the two clamping sleeves 40 can be fixed.

In FIGS. 11A to 11D, it is shown that the blade 21, when inserted into the receptacle 41, is guided by insertion bevels 45 at points, so that, irrespective of the position of the clamping sleeve 40 relative to the blade 21, a movement in FIG one of the recordings 41 takes place. The sword 21 can then be inserted between two ribs 42 in the receptacle 41, which is arranged between two adjacent peaks. The clamping sleeves 40 can be moved independently of each other in the mounting position, so that after adjusting the tension of the cable 4, the slider 20 is moved to the fixed position to fix the two clamping sleeves on the holder 3. During assembly, care must not be taken to ensure that the sword 21 is inserted into a receptacle 41, but by the insertion bevels 45 it catches itself in the corresponding receptacle 41. In Figure 1 2, a holder 3 is shown in the fixed position in which the slider 20 is inserted to fix the clamping sleeves 40 in the sleeves 35 and 36. In Figure 1 3A, a portion 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 on the holder 3, a guide roller 37 is rotatably mounted to deflect the cable 4 by about 90 °. In this case, two guide rollers 37 are rotatably mounted within the holder 3, each deflecting a portion of the cable 4. The deflection rollers 37 may be rotatable about an axis which is provided on the holder 3.

FIG. 14 shows a modified exemplary embodiment of a holder 3 'which is mounted on a middle rail 8 of a pull-out guide 1. The holder 3 'comprises a mounting portion for fixing to hooks 80 and 81 on the middle rail 8, the U-shaped receptacles 1 32 has, in each of which a hook 80 or 81 can be inserted. Incidentally, the holder 3 'is formed as in the previous embodiment and includes a slider 20 for adjusting the cable tension. As shown in Figures 15A and 15B, the holder 3 'is pushed onto the two hooks 80 and 81 of the center rail 8, so that the hook 80 engages in the U-shaped receptacle 1 32 and a bottom portion 1 30 between the hook 80th and the middle rail 8 secures. Similarly, the hook 81 engages in a U-shaped receptacle 133, so that the holder 3 'is fixed to the middle rail 8 via the two hooks 80 and 81.

In FIG. 16A, a pull-out guide 1 is shown, which has a middle rail 8, each having a front opening 33 and a rear opening 34. The openings 33, 34 are each arranged at different locations on the middle rail 8. Thereby, the device 2 can be fixed at different positions on the middle rail 8 of the pullout guide, whereby an individual adaptation to the depth of the pushers and / or to the existing depth in the installation space, in particular in the household appliance or furniture body can be made. In FIG. 16B, a pull-out guide 1 with a front hook 80 and a rear hook 81 is analogously arranged, the hooks 80, 81 being arranged at different positions on the middle rail 8. The positions of the openings 33, 34 and the hooks 80, 81 on the center rail 8 are purely exemplary and may vary. It is also possible the same to provide a plurality of openings 33, 34 and hooks 80, 81 on a middle rail 8, which are then only partially occupied during assembly.
