DETAILED DESCRIPTION OF THE INVENTION
(18) FIG. 1 shows a piece of furniture 1 with a schematic representation of a furniture body 2, on which a pushing element 3 in the form of a drawer is movably mounted. The pushing element comprises a front panel 4, which is arranged outside or inside the furniture body 2. In FIG. 2, the pushing element 3 is shown without front panel 4, and it comprises a base 5 on which side frames 6 are provided on opposite sides. In the area of the base 5, a rail 10 of a pull-out guide 8 is also shown, which is connected to the pushing element 3. This pushing element 3 is an underfloor system drawer system.
(19) As shown in FIG. 3, two adjacent latch receivers 11 and 12 are formed on rail 10, which are arranged next to each other in a longitudinal direction of rail 10. The latch receivers 11 and 12, which are designed as openings, are of different sizes, wherein a first latch receiver 12 in a longitudinal direction of rail 10 is shorter than a second latch receiver 11. However, both latch receivers 11, 12 can also be of the same length, or the first latch receiver 12 can be longer than the second latch receiver 11. In the second latch receiver 11 there is a latching projection 22, which limits movement of the rail 10 relative to an adapter 20.
(20) The adapter 20 is designed as a frame adapter and accommodates at least one profile of a side frame 6, which can be designed in one or more parts. The side frame 6 can have several adapters 20, wherein the adapter 20 facing the front panel 4 carries the latching projection 22.
(21) The adapter 20 can also be designed as a continuous adapter 20, so that the adapter 20 corresponds approximately to the length of the side frame 6. The front adapter 20 may have one or more receptacles for mounting the front panel 4. Further functional elements may be provided on the adapter 20, e.g. devices for attaching the base 5 or elements for sliding or latching a side frame wall.
(22) In FIG. 4, the rail 10 has been omitted and it can be seen that the adapter 20 forms a contact surface 21 against which the rail 10 rests with one surface, wherein a latching projection 22 projects from the contact surface 21, which is separated from the adapter 20 by a slot 23 transverse to the longitudinal direction and two slots 24 in the longitudinal direction of the rail 10, wherein a spring web 25 is formed between the two slots 24, which is formed integrally with the adapter 20. The slots 23 and 24 embrace the latching projection 22 in a Li-shape and thus ensure that the latching projection 22 can move perpendicularly to the contact surface 21. The adapter 20 is a component of the side frame 6 and forms the connecting means.
(23) The strip-shaped adapter 20 is connected at the end to a holder 30, which has a receptacle for inserting one end of the adapter 20, and an arm 31 embraces this end. The holder 30 is designed as an additional component, as shown in the exploded view in FIG. 5. The holder 30 comprises a slot-shaped receptacle 32 for insertion of one end of the adapter 20 and one end of the rail 10. The slot-shaped receptacle 32 is surrounded on one side by the arm 31 and on the opposite side by a block 33. On the block 33, a counterholder 34 is provided, which supports the spring web 25 with a support section 35, so that the holder 30 supports the latching projection 22 when the latter is pivoted out of the plane of the contact surface 21. A wall section 36 is also formed on the holder 30, which can be inserted into an opening in a side frame 6 of the pushing element 3. For mounting, the wall section 36 is inserted until one end of the strip-shaped adapter 20 engages in the slot-shaped receptacle 32 of the holder 30. As shown in FIGS. 6 and 7, the rail 10 also has a front web-shaped end 13 which can be inserted into the slot-shaped receptacle 32 together with the end section of the adapter 20. The web-shaped end 13 of rail 10 is open at the top so that the arm 31 is not hindered by any part of rail 10 when the pushing element 3 is lifted. The holder 30 also has an optionally provided, upwardly protruding projection 37 on the block 33, which can be inserted into a recess 27 on the adapter 20. Optionally, the holder 30 can also be fixed to the adapter 20 by means of an attaching means which is inserted into an opening 39 on a web 38.
(24) In the illustrated exemplary embodiment, the adapter 20 is also used to attach the base 5 of the pushing element. To attach the base 5, the adapter 20 has a groove-shaped receptacle 26 into which an edge section of the base 5 can be inserted.
(25) In order to be able to release the pushing element 3 after mounting it on the rail 10 of the pull-out guide 8, the pushing element 3 is first moved into an opening position. Then the pushing element 3 can be lifted in the region of the front panel 4 as shown in FIG. 8. When raised, the latching projection 22 slides over the latch receiver 11 on the rail 10 and can thus cause unlocking between the pushing element 3 and rail 10.
(26) In FIGS. 1 to 8 the pushing element 3 is fastened via the latch receiver 11, which is designed as an opening and in which the latching projection 22 engages in the mounted position. Thus, the frame adapter 20 with its latching projection 22 represents a first connection interface, in this exemplary embodiment, the connection between rail 10 and pushing element 3 is made on the outside of the rail 10, looking at the pushing element 3 from the front when assembled. The latch receiver 11 is thus a first attaching means for attaching a pushing element, which in this exemplary embodiment has a hollow side frame 6 on which one or more adapters 20 are provided in the longitudinal direction of the rail 10. On the rail, on the side opposite the latch receiver 11 in this example, a latching projection 90 is formed, which forms a second attaching means to which a further pushing element can be attached, for example a drawer with a side wall made of a solid material such as wood. This latching projection 90 has no function in FIGS. 1 to 8, as only the latch receiver 11 is in engagement with the adapter 20. However, the latching projection 90 can be used for a further pushing element, as explained below. Several latching projections or one or more latch receivers may also be formed on the opposite side.
(27) FIGS. 9 to 11 show a further exemplary embodiment of a device for attaching a pushing element 3, in which, in contrast to the previous exemplary embodiment, rail 10 is not held directly on holder 30, but a plug 15 is provided as an attachment part which is mounted on rail 10. The plug 15 comprises a strip-shaped section 16 which can be inserted into the curved rail 10. The strip-shaped section 16 has a latching projection 17 which can be inserted into an opening in the rail 10. The latching projection 17 can be located on the top of the section as shown. A web 18 is formed on a head section of the plug 15 projecting from the rail 10, which engages in the slot-shaped receptacle 32 of the holder 30. The area of the web 18 on the plug 15 is designed to be open at the top so that the arm 31 is not obstructed by a part of the rail 10 or the plug when the pushing element 3 is lifted off.
(28) As can be seen from the enlarged illustration in FIG. 10, a spring element 19 can be provided on the web 18, which is supported at one front end of the slot-shaped holder 32 and thus pretensions the holder 30 away from the rail 10 in the longitudinal direction of the rail 10.
(29) The plug 15 can also be equipped with the latch receivers 11,12 to attach the adapter 20 to the plug 15 via the latching projection 22. In addition or alternatively, the plug 15 could also have at least one latching projection 90 on the side opposite to the web 18 or the latch receivers 11,12 for the possibility of connection to a pushing element with another connection interface, for example a coupling device which can be retrofitted to the pushing element.
(30) In the mounted position shown in FIG. 11, the web 18 is inserted together with an end section of the adapter 20 into the slot-shaped receptacle 32, and the projection 37 is inserted into the recess 27 on the adapter 20. Otherwise, the latching projection 22 engages in the latch receiver 11 as in the first exemplary embodiment. In this exemplary embodiment, too, the latching projection 90 has no function when rail 10 is used with this pushing element 3 and has no connection to pushing element 3.
(31) FIG. 12 shows a piece of furniture 50 which has a furniture body 51 on which several pushing elements 52 are held in a displaceable manner. For this purpose, pull-out guides 8 are provided on opposite sides of a pushing element 52, on which the pushing element 52 is movably held. The pushing element 52 is designed as a drawer which comprises a front panel 53, side walls 54, a base 55 and a rear wall 56. The side walls 54 and the rear wall 56 are provided with a schematic grain as shown in the diagram in order to illustrate the formation of the side walls 54 and the rear wall 56 from a solid material, in particular from a wood-based material. This pushing element 52 is an underfloor drawer system.
(32) FIGS. 13A and 13B show a pull-out guide 8, which has a guide rail 9 and can be attached to a furniture body 51. Relative to the guide rail 9, the rail 10 can be moved and serves to hold the pushing element 52. The rail 10 includes an optional hook 14 on the rear side by means of which the pushing element 52 can be fixed to the rear wall 56, for example through an opening in the rear wall 56.
(33) The pull-out guide 8 also includes a self-closing mechanism 45, which has a guide element 46 for a driver 47 that can be coupled to an activator 48 that is fixed to the rail 10. The driver 47 can be preloaded to a retracted position by means of an energy storage device in a cartridge 49 in order to hold the pushing element 52 in a closed position via the coupling with the activator 48. The self-closing mechanism 45 can also have a damper to brake the pushing element 52 during a closing movement. Optionally, another or an additional drive mechanism can be provided on the pull-out guide 8, for example an ejecting device.
(34) At a front end of rail 10, a plug 60 is provided as an add-on part, which has a laterally protruding latching projection 61. In the assembled position, the latching projection 61 protrudes towards an interior space on the furniture body 51.
(35) The attachment of the pushing element 52 to the rail 10 of the pull-out guide 8 is explained below with reference to FIGS. 14 to 16. The element 52 is placed with the base 55 on the rails 10, with connecting means 62 being provided underneath base 55 for attaching pushing element 52 to rail 10. Each connecting means 62 comprises a housing mounted on the base 55 and/or the front panel 53, on which a spring web 63 with a guide bevel 64 is formed. On the spring web 63, a first latch receiver 65 and an adjacent latch receiver 66 are provided. The connecting means 62 is a so-called coupling unit, which is manufactured separately and is only connected to the pushing element 52 after it has been assembled, preferably detachably, e.g. by means of screws. The connection interface or the connecting means of the pushing element 52 is different from the connection interface or the connecting means of the pushing element 3 of the first two exemplary embodiments according to FIGS. 1 to 11. In the exemplary embodiment according to FIGS. 12 to 16, the connection between rail 10 and pushing element 52 is made in the assembled state on the inside of rail 10 looking at the pushing element 52 from the front.
(36) The pushing element 52 is placed on the two rails 10 in such a way that the end plug 60 is positioned at a distance from the front panel 53. Then the pushing element 52 can be moved in the closing direction on the rails 10 as shown in FIG. 15. When the pushing element 52 is moved, the plug 60 with the latching projection 61 comes into contact with the guide bevel 64 of the spring web 63 and pushes it inwards until the latching projection 61 engages with the first latch receiver 65.
(37) For complete assembly, the pushing element 52 is then pushed in further in the closing direction, optionally also after a previous pull-out movement, in order to engage the latching projection 61 in the second latch receiver 66, as shown in FIG. 16. The pushing element 52 is now in the assembled position, in which pulling on the front panel 53 transmits a force to the latching projection 61 and thus to the rail 10. On the housing of the connecting means 62, adjusting means 70 can also be provided to adjust the position of the front panel 53 in the height direction and/or in the lateral direction and/or in the depth. Such adjusting means 70 can therefore move the pushing element 52 relative to the rail 10 in at least one spatial direction.
(38) FIGS. 14 to 16 describe how to attach the pushing element 52 via the latching projection 61, which is formed on the plug 60. If the plug 60 is omitted, the pushing element 52 can also be attached via the latching projection 90, which is shown in FIG. 13. On the “inside” of rail 10 there are therefore two attaching means in the form of latching projections 61 or 90, and the pushing element 52 can be attached either to the integrally formed attaching means in the form of the latching projection 90 or to the attaching means on the plug 60.
(39) In FIGS. 17A and 17B, rail 10 is shown in two views. Rail 10 is made of a metal sheet and comprises two legs on opposite sides, wherein one leg is provided with the two latch receivers 11 and 12 and the other with a further latch receiver 80 in the form of a recess on the opposite side, which can be used as an alternative for attaching a second pushing element with a different connection interface to the first pushing element. The latch receiver 11 forms a first attaching means for attaching a first pushing element, while the latch receiver 80 is a second attaching means for attaching a second pushing element. Several latch receivers 80 can also be present. Instead of a latch receiver 80, a latching projection 90 can also be formed on the rail 10, as described above. In the front area, rail 10 has a channel 100, which is U-shaped with two vertical legs and an upper opening, and which, when mounted, allows the pushing element to be removed without tools by lifting it upwards. In order to prevent this lifting upwards from occurring unintentionally, at least one vertical leg, preferably both vertical legs, of the channel 100 can have an edge at the upper end which is directed into the channel as an undercut, which causes a certain resistance to lifting upwards, which must first be overcome when the channel is lifted intentionally. In the assembled state, for example, the web 67 of connecting means 62 shown in FIG. 14 engages with channel 100.
(40) In FIGS. 18A to 18C, an end section of rail 10 is shown in several views. Rail 10 is fitted with a plug 60 at the end, with a latching projection 61 protruding from the side. On the opposite side to the latching projection 61, two latch receivers 71 and 72 are formed on the plug 60, which are similar in shape to the latch receivers 11 and 12 explained in FIGS. 1 to 8. A pushing element 3 can also be attached via the latching projection 22 and the latch receivers 11 and 12 on the plug 60, on which corresponding latch receivers 71 and 72 are formed. The plug 60 is provided with a channel 75, which is U-shaped with two vertical legs and an upper opening. This allows the pushing element 3 to be lifted upwards for disassembly, as shown in FIG. 8. In order to prevent this upward lifting from occurring unintentionally, an edge 76 directed into the channel 75 can be formed as an undercut on at least one vertical leg, preferably on both vertical legs, of the channel 75 at the upper end, which represents a certain resistance against upward lifting which needs to be overcome in the case of intended lifting. In the assembled state, for example, the web 67 of connecting means 62 shown in FIG. 14 engages with channel 75. An edge 76 as an undercut is shown in FIG. 18D.
(41) A slightly modified design of plug 60 is shown in FIG. 18E. In addition, plug 60 has a guide bevel 77 on at least one wall of channel 75, preferably on the two opposite walls. The guide bevel 77 widens towards the rear when viewed from the front so that it provides a guiding aid when a drawer is fitted. The plug 60 can be fixed in place via the latch receivers 11 and 12.
(42) The plug 60 thus forms first and second attaching means to attach either the pushing element 3 or the pushing element 52, in this way, a single pull-out guide 8 with a rail 10 and the plug 60 can be used to fix different pushing elements. If the plug 60 is omitted, the first and second attaching means can also be formed integrally with the rail 10, for example in the form of latch receivers 11 and 12 or a latching projection 90. The first attaching means can also be arranged on the plug 60 and the second attaching means on the rail 10 or vice versa.
(43) The first and second attaching means can be either the same or different in design and are used to mount either a first pushing element or a second pushing element to the rail 10, preferably without tools, without having to make any modifications to the rail 10.
