Description

[0001] The present invention relates to a method for assembling a drawer element, as well as a kit for the movable mounting of a drawer element with a first and a second pull-out guide that 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 bodies or household appliances.

[0002] 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 synchronization device. The synchronization device comprises deflection rollers on a center rail of the pull-out guide and brackets for securing a cable pull to the stationary guide rail and the movable running rail. This synchronization device has proven itself to be effective, but installation is relatively complex, as a bracket with deflection rollers is mounted in the rear area of ​​the center rail using screws. In addition, to tension the cable pull, a locking element must be mounted on a tensioning device, which is inserted into grooves on a clamping sleeve of a housing.The problem here is that the locking element can only be inserted if the grooves are aligned, which is particularly difficult in poor lighting conditions. Furthermore, the locking element can be removed from the tensioning device and lost. Installing the cable pull with the individual cable pull sections is also comparatively complex, as each cable pull section is mounted separately.

[0003] It is therefore an object of the present invention to provide a method for assembling a sliding element and a kit for displaceably mounting a sliding element, which enable assembly in a simple manner and enable efficient transport.

[0004] This object is achieved by a method having the features of claim 1 and a kit having the features of claim 5.

[0005] In the method according to the invention, the two pull-out guides are first secured on opposite sides, and then a device for synchronizing the movement of the movable rails of the two pull-out guides is mounted. A holder with at least one deflection element is plugged or snapped onto each pull-out guide, and a cable is placed around a pulley pre-mounted on the pull-out guide. Then, at least one rail of each pull-out guide is coupled to the cable via a connecting device, and the tension of the cable is adjusted via a device for adjusting the cable tension. Assembly can thus be completed in just a few steps, particularly without the need for tools, since the holders with the at least one deflection element are plugged or snapped onto the guide.In addition, the cable pull can be placed around the pulley as a pre-assembled unit and attached or snapped onto the rail via a connecting device. This allows a pull-out system with two pull-out guides to be assembled quickly, allowing a drawer element to be secured to the pull-out guides.

[0006] To adjust the tension of the cable pull, the invention provides a slider on at least one deflection element, which slider is moved from an installation position to the fixed position. The slider can preferably be used to fix two clamping sleeves, each provided with multiple receptacles, in different positions relative to a housing of the holder. This reduces the number of components because the slider can be used to fix two clamping sleeves to the housing simultaneously. For easy installation, guide bevels can be provided on the slider and / or the receptacles on the clamping sleeve, which facilitate guiding the slider into the receptacles.

[0007] The connecting device is preferably mounted in such a way that a holder is provided, fixed to the stationary guide rail and to the movable guide rail, into which a coupling element connected to two sections of the cable pull can be inserted, in particular by locking or clamping. Two ends of a cable pull can then be mounted to a rail simultaneously via the coupling element.

[0008] With 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 the need for tools. The two holders with the deflection elements are preferably plugged or snapped onto a rear area of ​​a rail, in particular the center rail. Furthermore, the cable tension can be adjusted via spring-loaded clamping sleeves, preferably in one of the two holders. The clamping sleeves are then secured in the adjusted position with a slider that can be inserted into a clamping sleeve receptacle to fix it in the desired position on a housing of the holder. Two clamping sleeves can be fixed simultaneously via the slider.The kit can thus consist of three units: the two drawer slides and the device for synchronizing the movement of the movable rails. The device can be installed tool-free in just a few steps. The synchronization device secures the slider captively to the holder, which can only be moved between a mounting position with a movable clamping sleeve and a fixed position with a fixed clamping sleeve. In addition, a stop can be formed on the clamping sleeve to permanently fix the clamping sleeve to the holder with the deflection element.

[0010] A kit for the movable mounting of a drawer 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 secured to the side wall via mounting brackets 10. To synchronize the 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 pulleys 2, a cable pull 4, which can be made from one or more cable pull sections, and coupling elements 5 for coupling the cable pull 4 to the pull-out guides 1.Furthermore, two sleeve-shaped sheaths 6 are arranged between the two holders 3, which are part of a device for tensioning the cable pull 4.

[0011] The Fig. The kit shown in Figure 1A essentially consists of three units, namely the two drawer guides 1 and the device 2 for synchronizing the movement of the movable rails. The device 2 is Fig. 2B is shown in the assembled position, with assembly being carried out without tools.

[0012] In Fig. 1B shows that the two holders 3 are fixed to a rear area of ​​a center rail 8 of each drawer guide 1. Each drawer guide 1 has a stationary guide rail 7, which is fixed to the mounting brackets 10, a center rail 8, and a running rail 9, to which a sliding element, such as a drawer, can be fixed. Furthermore, a deflection pulley 11, around which the cable pull 4 is guided, is rotatably mounted on the center rail 8 in the front area. The cable pull 4 is coupled to the stationary guide rail 7 via a coupling element 5 and to the running rail 9 via another coupling element 5. The cable pull 4 is designed to be circumferential and is guided by the coupling element 5 from the guide rail 9 of one 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, in order to be guided from there via the deflection roller 11 back to a coupling element 5 on the guide rail.

[0013] In Fig. Figure 1C shows that the kit can be arranged in a very space-saving manner for transport, thus enabling very cost-effective transport. This arrangement is not possible with the pull-out system described in DE 10 2013 113 672 A1, as the synchronization device is already connected to the pull-out guide at the factory prior to transport.

[0014] In the Fig. 2A and Fig. Figure 2B shows the assembly of a holder 3, which is mounted on the center rail 8. For this purpose, a support web 30 of a housing with two protruding hooks 31 and 32 is positioned at openings 33 and 34 of the center rail 8, with 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 enable the holder 3 to be pivoted and locked onto the center rail 8 without tools.

[0015] In the Fig. 2A and Fig. 2B further shows a driver 12 to 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 retaining webs 13 and two receiving webs 14 protrude.

[0016] The driver 12 is in the Fig. 3A and Fig. 3B is shown enlarged. During assembly, the cylindrical coupling element 5 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 section 52, by means of which the cable pull 4 is fixed to the coupling element 5. The cylindrical mounting sections 52 are arranged in the longitudinal direction of the cable pull 4 between the two holding webs 13 and are thus also secured against movement in the longitudinal direction of the cable pull 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 plugged-on position, the receiving webs 14 encompass the cylindrical mounting sections 52, as shown in Fig. 3B is shown.

[0017] In the Fig. 4A and Fig. 4B shows a coupling element 5 in detail, comprising a cylindrical sleeve 50 with a plurality of locking elements 51 formed on both sides. A cylindrical mounting section 52, which is attached to the cable pull 40, is inserted into the cylindrical sleeve 50 on each side and has a groove 53 formed thereon. The two mounting sections 52 engage with the groove 53 on the respective locking element 51 of the sleeve 50, so that two sections of the cable pull 4 are connected to one another.

[0018] In Fig. Figure 5 shows the area of ​​a deflection pulley 11, which is arranged adjacent to a driver 12 on the guide rail 7. The deflection pulley 11 is rotatably mounted on the center rail 8 and deflects the cable pull 4 by approximately 180°.

[0019] In Fig. Figure 6 shows the deflection pulley 11 in detail. The deflection pulley 11 comprises a U-shaped receptacle 15 for the cable pulley 4, with one side wall 16 toward the center rail 8 being higher than an opposite side wall 17. The deflection pulley 11 also has a bearing section 18 that is inserted into the center rail 8.

[0020] In the Fig. 7A and Fig. 7B shows the holder 3, on which a device for tensioning the cable pull 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 slider 20 is provided on the holder 3, which is movable back and forth between two positions. The housing further comprises two sleeves 35 and 36, each of which houses a tensioning sleeve 40 through which the cable pull 4 is passed. Fig. 7B shows a section through the housing of the holder 3, and it can be seen that the slide 20 is arranged in an assembly position in which a blade 21 of the slide 20 is arranged at a distance from the clamping sleeves 40. The slide 20 comprises arms 22 with locking recesses 23 on opposite sides, each arm 22 having an inwardly projecting stop 24, which ensures that the slide 20 is captively secured to the holder 3.

[0021] In order to move the slider 20 from the mounting position with movable clamping sleeve 40 into a fixed position, it is inserted into the holder 3, as shown in the Fig. 8A and Fig. 8B. By inserting, the two arms 22 are first unlocked from the first locking position and then pushed into the holder 3 until a second locking recess 23 on the arm 22 engages with a locking projection 38 on the holder 3. In the process, the blade 21 on the slide 20 is also inserted between the sleeves 35 and 36, with a clamping sleeve 40 being fixed in each of the sleeves 35 and 36 via the blade 21.

[0022] In the Fig. 9A and Fig. 9B shows a clamping sleeve 40 arranged in the sleeves 35 and 36 of the holder 3. The clamping sleeve 40 comprises an inner cavity through which the cable 4 is guided and is inserted into an end piece 60 of the casing 6. On the outside of the clamping sleeve 40, several groove-shaped receptacles 41 are formed, which are separated from one another by ribs 42. The receptacles 41 are provided at least in the area of ​​the blade 21, but can also be provided at other circumferential locations. The clamping sleeve 40 is preloaded away from the holder 3 by a spring 61, wherein the maximum clamping travel is predetermined by a stop 44 that protrudes on an arm 43 of the clamping sleeve 40. The stop 44 bears against the sleeve 35, as shown in Fig. 9 B, so that the clamping sleeve 40 can be pushed further into the holder 3 from this position, but can no longer be pulled out any further.

[0023] The tension of the cable pull 4 can be adjusted via the position of the clamping sleeve 40. The cable pull 4 is guided through the casing 6, whereby upon movement of one of the two clamping sleeves 40, between which the casing 6 is arranged, the travel distance for the cable pull 4 in the casing 6 remains constant, since the casing simply sags somewhat more when the travel distance is shortened. The cable pull 4 is tensioned when the clamping sleeve 40 is moved out of the holder 3, and relaxed when the clamping sleeve 40 is pushed into the holder 3 against the force of the spring 61. The spring 61 allows the tension of the cable pull 4 to be adjusted, and assembly tolerances can be compensated.

[0024] In Fig. 10, the slider 20 and the two clamping sleeves 40 are shown without the housing of the holder 3. The slider 20 engages the clamping sleeves 40 with the arms 22 in a U-shape, with the clamping sleeves 40 being secured via the central blade 21, which is inserted into a groove-shaped receptacle 41 of the clamping sleeves 40. Thus, the position of the two clamping sleeves 40 can be fixed with a single slider 20.

[0025] In the Fig. 11A to 11D show that the blade 21 is guided by insertion bevels 45 on the tips when inserted into the receptacle 41, so that movement into one of the receptacles 41 occurs regardless of the position of the clamping sleeve 40 relative to the blade 21. The blade 21 can then be inserted between two ribs 42 into 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 adjusting the tension of the cable 4, the slider 20 is moved into the fixed position to fix the two clamping sleeves to the holder 3. During assembly, it is not necessary to pay close attention to ensuring that the blade 21 is inserted into a receptacle 41; instead, the insertion bevels 45 allow it to catch itself in the corresponding receptacle 41.

[0026] In Fig. 12, 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 Fig. 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 pulley 37 is rotatably mounted on the holder 3 in order to deflect the cable 4 by approximately 90°. Two deflection pulleys 37 are rotatably mounted within the holder 3, each deflecting a section of the cable 4. The deflection pulleys 37 can be rotatable about an axis provided on the holder 3.

[0027] In Fig. Figure 14 shows a modified embodiment of a holder 3' that is mounted on a center rail 8 of a drawer slide 1. The holder 3' comprises a mounting section for attachment to hooks 80 and 81 on the center rail 8, which has U-shaped receptacles 132 into which a hook 80 or 81 can be inserted. Otherwise, the holder 3' is designed as in the previous embodiment and includes a slider 20 for adjusting the cable tension.

[0028] As in the Fig. 15A and Fig. 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 132 and secures a bottom portion 130 between the hook 80 and the center rail 8. Similarly, the hook 81 engages in a U-shaped receptacle 133, so that the holder 3' is fixed to the center rail 8 via the two hooks 80 and 81.

[0029] In Fig. 16A shows a pull-out guide 1, which has a center rail 8, each with a front opening 33 and a rear opening 34. The openings 33, 34 are arranged at different locations on the center rail 8. This allows the device 2 to be fixed at different positions on the center rail 8 of the pull-out guide, allowing individual adjustment to the depth of the drawer elements and / or to the existing depth in the installation space, in particular in the household appliance or in the furniture body. Fig.16B is a similar illustration of a drawer guide 1 with a front hook 80 and a rear hook 81, with the hooks 80, 81 arranged at different positions on the center rail 8. The positions of the openings 33, 34 or the hooks 80, 81 on the center rail 8 are purely exemplary and may vary. It is also possible to provide several openings 33, 34 or hooks 80, 81 on a center rail 8, which are then only partially occupied during assembly.
