DETAILED DESCRIPTION OF THE INVENTION
(19) A construction kit for the displaceable mounting of a drawer element comprises a first pullout guide 1, which is installable on a first side wall of a furniture body or a household appliance, and a second pullout guide 1, which is installable on an opposing side wall. In this case, each pullout guide 1 is fixable via installation angles 10 on the side wall. To synchronize a movement of the pullout guides, a device 2 is provided, which connects the two pullout guides 1 to one another. The device 2 for synchronizing the movement of the movable rails comprises two holders 3 having in each case at least one, preferably two deflection elements, in particular two deflection rollers, a cable pull 4, which can be produced from one or multiple cable pull sections, and coupling elements 5, to couple the cable pull 4 on the pullout guides 1. Furthermore, two sleeve-shaped jackets 6, which are part of a device for tensioning the cable pull 4, are arranged between the two holders 3.
(20) The construction kit shown in FIG. 1A thus substantially consists 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 the installed position in FIG. 2B, wherein the installation is performed without tools.
(21) FIG. 1B shows that the two holders 3 are fixed on a rear region of a middle rail 8 of each pullout guide 1. Each pullout guide 1 has a stationary guide rail 7 in this case, which is fixed on the installation angles 10, the middle rail 8, and a slide rail 9, which can be fixed on a drawer element, such as a drawer. Furthermore, a deflection roller 11, around which the cable pull 4 is guided, is mounted so it is rotatable on the middle rail 8 in the front region. The cable pull 4 is coupled in this case via a coupling element 5 to the stationary guide rail 7 and a further coupling element 5 to the slide rail 9. The cable pull 4 is designed to circulate and is guided by the coupling element 5 from the slide rail 9 of one pullout guide 1 via the two holders 3 to a coupling element 5 on the guide rail 7 of the other pullout guide 1, to be guided from there via the deflection roller 11 back to a coupling element 5 on the slide rail.
(22) FIG. 1C shows that the construction kit can be arranged in a very space-saving manner for transportation and a very cost-effective transportation is thus implementable. This arrangement is not possible in the pullout guide of DE 10 2013 113 672 A1, since the device for synchronization is already connected to the pullout guide at the factory before the transportation.
(23) FIGS. 2A and 2B show the installation of a holder 3, which is installed on the middle rail 8. For this purpose, a contact web 30 of a housing having two protruding hooks 31 and 32 is positioned at openings 33 and 34 of the middle rail 8, wherein firstly the rear hook 32 is inserted into the opening 34 and then the front hook 31 is inserted into the opening 33. The hooks 31 are formed as catch hooks in this case and thus enable pivoting in and latching of the holder 3 on the middle rail 8 without tools.
(24) Furthermore, a driver 12 is shown in FIGS. 2A and 2B, on which a coupling element 5 can be installed. The driver 12 has a section installed on the slide rail 9 or a guide rail 7, from which two holding webs 13 and two receptacle webs 14 protrude.
(25) The driver 12 is shown enlarged in FIGS. 3A and 3B. During the installation of the cylindrical coupling element 5, it is inserted between the two receptacle webs 14, so that the coupling element 5 can be held immovably in the axial direction between the two receptacle webs 14. The receptacle webs 14 each enclose one cylindrical installation section 52 in this case, by means of which the cable pull 4 is fixed on the coupling element 5. The cylindrical installation 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 a movement in the longitudinal direction of the cable pull 4. The coupling element 5 can be plugged from above onto the receptacle webs 14, since the receptacle webs 14 and holding webs 13 form a U-shaped receptacle together with the driver 12. In the plugged-on position, the receptacle webs 14 enclose the cylindrical installation sections 52, as shown in FIG. 3B.
(26) A coupling element 5 is shown in detail in FIGS. 4A and 4B, which has a cylindrical sleeve 50, which has multiple catch elements 51 formed on both sides. A cylindrical installation section 52, which is fastened on the cable pull 4, and on which a groove 53 is formed, is plugged into the cylindrical sleeve 50 on each of the two sides. The two installation sections 52 latch with the groove 53 on the respective catch element 51 of the sleeve 50 such that two sections of the cable pull 4 are connected to one another.
(27) The region of a deflection roller 11, which is arranged adjacent to a driver 12 on the guide rail 7, is shown in FIG. 5. The deflection roller 11 is mounted so it is rotatable on the middle rail 8 in this case and deflects the cable pull 4 by approximately 180.
(28) The deflection roller 11 is shown in detail in FIG. 6. The deflection roller 11 comprises a U-shaped receptacle 15 for the cable pull 4, wherein one side wall 16 is formed higher toward the middle rail 8 than an opposing side wall 17. The deflection roller 11 furthermore has a bearing section 18, which is plugged into the middle rail 8.
(29) The holder 3, on which a device for tensioning the cable 4 is provided, is shown in FIGS. 7A and 7B. The holder 3 comprises a housing, on which the contact web 30 having the two hooks 31 and 32 is integrally formed. Furthermore, a slide 20 is provided on the holder 3, which is movable back and forth between two positions. The housing furthermore has two sleeves 35 and 36, in each of which a tensioning sleeve 40 is arranged, through which the cable pull 4 is guided. A section through the housing of the holder 3 is shown in FIG. 7B in this case, and it is recognizable that the slide 20 is arranged in an installation position, in which a sword 21 of the slide 20 is arranged spaced apart from the tensioning sleeves 40. The slide 20 comprises arms 22 having catch recesses 23 on opposing sides, wherein each arm 22 has an inwardly protruding stop 24, which ensures that the slide 20 is fixed captively on the holder 3.
(30) To move the slide 20 from the installation position having movable tensioning sleeve 40 into a fixed position, it is pushed into the holder 3, as shown in FIGS. 8A and 8B. By way of the pushing in, firstly the two arms 22 are unlocked from the first catch position and then pushed far enough into the holder 3 that a second catch recess 23 on the arm 22 engages with a catch projection 38 on the holder 3. In this case, the sword 21 on the slide 20 is also inserted between the sleeves 35 and 36, wherein one tensioning sleeve 40 is fixed in each of the sleeves 35 and 36 via the sword 21.
(31) A tensioning sleeve 40, as is arranged in the sleeves 35 and 36 of the holder 3, is shown in FIGS. 9A and 9B. The tensioning sleeve 40 comprises an inner cavity, in which the cable pull 4 is guided through, and is pushed into an end piece 60 of the jacket 6. Multiple grooved receptacles 41, which are separated from one another via ribs 42, are formed on the outer side of the tensioning sleeve 40. The receptacles 41 are provided at least in the region of the sword 21, but can also be provided on other peripheral points. The tensioning sleeve 40 is pre-tensioned away from the holder 3 via a spring 61, wherein the maximum tensioning distance is predefined by a stop 44, which protrudes on an arm 43 of the tensioning sleeve 40. The stop 44 bears on the sleeve 35, as shown in FIG. 9B, so that the tensioning sleeve 40 can be pushed farther into the holder 3 from this position, but cannot be pulled farther out.
(32) The tension of the cable pull 4 can be set via the position of the tensioning sleeve 40. The cable pull 4 is guided through the jacket 6, wherein in the event of a movement of one of the two tensioning sleeves 40, between which the jacket 6 is arranged, the route for the cable pull 4 in the jacket 6 remains constant, since it simply sags somewhat more strongly in the event of a shortening of the route. The cable pull 4 is tensioned when the tensioning sleeve 40 is moved out of the holder 3, and relaxed when the tensioning sleeve 40 is pushed into the holder 3 against the force of the spring 61. The tension of the cable pull 4 may be set by the spring 61, and installation tolerances can be compensated for.
(33) In FIG. 10, the slide 20 and the two tensioning sleeves 40 are shown without the housing of the holder 3. The slide 20 encloses the tensioning sleeves 40 in a U shape with the arms 22, wherein fixing of the tensioning sleeves 40 is performed via the middle sword 21, which is inserted into a grooved receptacle 41 of the tensioning sleeves 40. Therefore, the position of the two tensioning sleeves 40 can be fixed using a single slide 20.
(34) FIGS. 11A to 11D show that the sword 21 is guided at tips by insertion bevels 45 upon insertion into the receptacle 41, so that independently of the position of the tensioning sleeve 40 in relation to the sword 21, a movement occurs into one of the receptacles 41. The sword 21 can then be inserted between two ribs 42 into the receptacle 41, which is arranged between two adjacent tips. The tensioning sleeves 40 can be moved independently of one another into the installation position in this case, so that after the setting of the tension of the cable pull 4, the slide 20 is moved into the fixed position in order to fix the two tensioning sleeves on the holder 3. During the installation, it does not have to be ensured exactly that the sword 21 is inserted into a receptacle 41, but rather it catches on its own in the corresponding receptacle 41 due to the insertion bevels 45.
(35) A holder 3 is shown in the fixed position in FIG. 12, in which the slide 20 is pushed in in order to fix the tensioning sleeves 40 in the sleeves 35 and 36. In FIG. 13A, a part of the housing of the holder 3 was omitted, and it is recognizable that the slide 20 secures the tensioning sleeves 40 in the sleeves 35 and 36 against a movement in the longitudinal direction of the cable pull 4. Furthermore, it can be seen that a deflection roller 37 is mounted so it is rotatable on the holder 3, to deflect the cable pull 4 by approximately 90. In this case, two deflection rollers 37 are mounted so they are rotatable inside the holder 3, each of which deflects one section of the cable pull 4. The deflection roller 37 can be rotatable in this case about an axis which is provided on the holder 3.
(36) FIG. 14 shows a modified exemplary embodiment of a holder 3, which is installed on a middle rail 8 of a pullout guide 1. The holder 3 comprises an installation section for fixing at hooks 80 and 81 on the middle rail 8, which has U-shaped receptacles 132, into each of which a hook 80 or 81 is insertable. The holder 3 is otherwise designed as in the preceding exemplary embodiment and comprises a slide 20 for setting the cable tension.
(37) As shown in FIGS. 15A and 15B, 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 manner, the hook 81 engages in a U-shaped receptacle 133, so that the holder 3 is fixed via the two hooks 80 and 81 on the middle rail 8.
(38) FIG. 16A shows a pullout guide 1, which has a middle rail 8 having a front opening 33 and a rear opening 34. The openings 33, 34 are each arranged at different points on the middle rail 8.
(39) The device 2 can thus be fixed at different positions on the middle rail 8 of the pullout guide, whereby an individual adaptation to the depth of the drawer element and/or the existing depth in installation space, in particular in the household appliance or in the furniture body, can be performed. In FIG. 16B, a pullout guide 1 similarly having a front hook 80 and a rear hook 81 is shown, wherein the hooks 80, 81 are arranged at different positions on the middle rail 8. The positions of the openings 33, 34 and/or the hooks 80, 81 on the middle rail 8 is solely by way of example and can vary. It is also possible to provide multiple openings 33, 34 and/or hooks 80, 81 at the same time on a middle rail 8, which are then only partially occupied during the installation.
