Description

The invention relates to a pull-out device for pull-out furniture parts, in particular Drawers, one on both sides of the pull-out furniture cabinet rail that can be fixed to the furniture body with an upper and a lower one Catwalk and a connecting side catwalk, one on the pull-out furniture part lockable pull-out rail with an upper and a lower catwalk and a side bar connecting them and a middle rail with an in the area between the catwalks of the extending rail projecting upper catwalk and has a side web extending downward therefrom, whereby to shift the middle rail relative to the body rail and the Pull-out rail are provided opposite the central rail and the rollers between the upper runway of the middle rail and the runways of the pull-out rail running rollers are held by at least one carriage and are spaced from each other and in the area of the rear end of the central rail a roller is rotatably mounted on its side bridge, with the walkways the body rail interacts, and in a central region of the longitudinal extent a carrier roller rotatable on the center rail on the center rail is mounted on the underside of the lower catwalk of the pull-out rail and rolls on the top of the upper runway of the body rail.

At least for a pull-out piece of furniture, for example a drawer To reach a full extension from the furniture body, telescopic extensions are different Design known, in which the individual rails telescopic are pullable apart. For load transfer between the rails rolling elements in the form of balls or rollers are provided, with excerpts from the rolls are known, on the one hand, in which the rolls are on Axes of the rails are rotatably mounted, on the other hand, such extracts which are arranged between the rails, which run the rollers store and space. Although the vast majority of the pull-out devices either only axially supported or only in rollers shows, some hybrid designs have already become known, in which Transfer the load between two of the rails with axle-mounted castors and rollers mounted in carriages between the other two rails are.

The disadvantage of conventional telescopic pull-outs is that they are pull-out Pull-out rail attached to the furniture part and the middle rail one after the other be pulled out, with the pull-out rail during the pull-out movement hits its end stop. Excerpts have therefore already been developed where additional measures are provided to ensure a simultaneous or to achieve synchronized extension of the rails when pulling out. When pulling out DE 92 19 064 U1 there is, for example, a pulley around guided traction means provided by which the movement of the between the carriage arranged on the individual rails is synchronized. Furthermore, it is known to rotatably mount a driving roller on the central rail, that rolls between the catwalks of the carcass rail and the pull-out rail. Such synchronized telescopic extensions are, for example, from AT 392 883 B and EP 11 90 646 A1. These are extracts the "hanging" design, in which the slide rail is moved Compared to the middle rail serving rollers below that for displacement the middle rail opposite the body rail serving rollers are arranged. The reverse arrangement of the rollers is subsequently called called "standing" type.

A synchronized telescopic extension of the standing type, one on the middle rail has a rotatably mounted driving roller, is from AT 372 830 known. All castors of this pull-out are rotatably mounted on axles that the rails are attached to both the lower and the upper web the middle rail rotates two spaced rollers are stored and in relation to the pull-out direction the pair of rollers above in the front section, the pair of rollers below, however, in the back Section of the corresponding vertical webs of the middle rail. ever depending on the position of the load in the drawer, the roller arrangement of the AT 372 830 cause the inserted rails to tilt slightly against each other, which impair the smoothness of the guide when it is subsequently pulled out can and due to the inclined front panel of the Drawer leads to an unsatisfactory aesthetic sight.

Further telescopic pull-outs of the upright type with axle-mounted castors emerge from AT 349 170 B and DE 24 37 910 A1, with these Pullers no synchronized running of the rails. A synchronous telescopic extension the standing type, in which between all rails Rollers mounted in carriages are provided, is also from the already mentioned DE 92 19 064 U1 known.

EP 0 761 133 A1 describes a synchronized telescopic pull-out known type, in which between the pull-out rail and the middle rail Rolling elements mounted in carriages are arranged and for load transmission between the middle rail and the carcass rail further on the Center rail in a rear area of the same rotatably mounted roller is provided. For load transfer from the one that carries the pull-out furniture part Pull-out rail on the cabinet rail also serves as the one on the middle rail rotatably mounted driving roller, which is on the middle rail by means of an axis or can be axleless. The pull-out rail is in a downward direction attached to the open side wall frame of the drawer. For lateral guidance of the middle rail at least one is preferred at the front end of the body rail arranged glider made of plastic. For fastening the cabinet rail the lower walkway of the cabinet rail is extended on the furniture body and at its end remote from the side bridge with a vertically upward extending fastening web provided. This fastening web extends extends over the height of the middle rail and points in its above the middle rail lying area in the longitudinal direction of the body rail from each other spaced holes through which the puller on the furniture body is screwable. To attach the pull-out device to the furniture body with the drawer removed and the pull-out device pulled out the fastening web is screwed to the furniture body. As a result, the Side wall frames are placed on the pull-out rails and fastened to them.

The object of the invention is to provide an improved pull-out device at the beginning Provide mentioned type, which requires a relatively low cost of materials Rails has a high running culture and simple and inexpensive can be produced. According to the invention, this is achieved with a pull-out device the features of claim 1.

In an advantageous embodiment of the invention it is provided that in the upper Catwalk of the body rail in the area of the front end of the body rail one extending to the rear of the front roller of the body rail Cutout for inserting the rear roller of the center rail into the Area between the two catwalks of the body rail is formed. advantageously, are attached to the furniture body of the two Body rails and when attached to the pull-out furniture part two pull-out rails and in the interconnected state of the middle rails and the pull-out rails insert the middle rails into the body rails or removable from these. This results in a very advantageous mounting option for the pull-out. First, the pull-out rail in the interconnected state of the rails on the pull-out Furniture part, for example the drawer can be attached. In this condition can also the pull-out furniture part with the pull-out device attached to it be transported. The body rails are then used for installation in the furniture body unhooked from the middle rails and the body rails can can be screwed onto the furniture body without this being a hindrance comes through the middle rails. As a result, the middle rails again inserted into the cabinet rails attached to the furniture body.

5 to 9, a panel or side wall frame of the drawer is placed on the pull-out rail. The figures have different scales.

In the embodiment shown in the figures, only those seen from vome rails arranged on the left side of the pull-out furniture part shown, which to be arranged on the other side of the pull-out furniture part Rails are mirror-symmetrical.

The on a furniture body 9, of which a section is shown schematically in Fig. 8 is to be attached body rail 20 has a C-shaped cross section and includes an upper and a lower catwalk 24, 25 and one vertical catwalks 23 connecting these catwalks. The catwalks 24, 25 are each have a stepped design and each have two horizontal staggered heights Sections on. The lower catwalk 25 also has its on the side catwalk opposite end an upward bend 26. The assembly on Furniture body 9, for example a wall unit, takes place in this embodiment with the interposition of several in the longitudinal direction of the body rail 20 spaced apart and fixed on the side web 23 Connecting parts 10. In the side web there are through holes 27 formed, which are aligned with holes in the connecting parts 10. Through this Bores, the body rail 20 is screwed onto the furniture body 9. In the area of the front end 21 of the body rail with respect to the pull-out direction 20 is a roller 1 on the side web 23 on the side of the catwalks 24, 25 rotatably mounted, on an axis attached to the side web 23. In the area of the rear end 22 of the body rail 20 is on the same side of the Side web 23 a stop 28 is arranged.

The pull-out rail 40, whose front end in relation to the pull-out direction with the reference number 41 and its rear end with the reference number 42 have upper and lower catwalks 44, 45, the upper Catwalk wider, in the exemplary embodiment shown about twice as wide as the lower catwalk is 45. The two catwalks are through a vertical side catwalk 43 connected to each other. From the end facing away from the side web 23 upper runway 44 starts a downward vertical web 46. With Except for the opening between the end of the lower runway 45 and the Vertical web 46, the pull-out rail is thus rectangular in cross section, in the shown Embodiment designed approximately square. 5 to 9 is a cover 17 or side wall frame covering the pull-out rail 40 shown a drawer through which the pull-out rail 40 with the extendable Furniture part 16 (see. Fig. 8) is connected. The aperture 17, which is part of the Pull-out device or be considered part of the pull-out furniture part can, is open at the bottom and has pull-out rail 40 on both sides running vertical webs, which are connected to each other via a bridge are. The outer vertical web extends below the side web 43 and thereby at least partially covers the middle rail. The inner one Side web extends to the lower end of the pull-out device and points a laterally projecting support bridge for supporting the pull-out furniture part 16 on.

The middle rail lying between the body rail 20 and the pull-out rail 40 30 has an upper catwalk 34 and a lower catwalk 35. The the upper catwalk 34 extends between the two catwalks 44, 45 the pull-out rail 40 area. On the side bar 43 of the pull-out rail 40 facing away from the upper catwalk 34 goes from this downwardly extending side web 33. The side web 33 is with a Provide gradation so that it is a little closer to the furniture body 9 upper section and a little closer to the pull-out furniture part 16 has lower section. At the lower end of the side web 43 closes an upwardly extending connecting web on this via a bend 36 on, from whose upper end the lower catwalk 35 extends. On his the bottom of the connecting walkway is the lower walkway with one after provided below bend 37.

In the area of the rear end 32 of the central rail in relation to the pull-out direction 30 on the side web 33 is one over the lower end of the side web 33 downwardly projecting roller 2 rotatably mounted on the side web 33, namely via an axis attached to the side web 33. The roller 2 is on the Body rail 20 or the furniture body 9 side of the side web 33 arranged. In a central area of the longitudinal extension of the central rail 30 is on its side web 33 on the same side as the roller 2 one Driving roller 3 rotatably mounted. The driving roller 3 consists at least in an area of a soft elastic adjoining its outer circumference Material 4 (Fig.8), this soft elastic material here from one on a hub 18 made of an inelastic plastic tread is formed. The driving roller 3 is in the embodiment shown with play mounted on an axle 38 fastened to the side web 33. In principle conceivable and Axle-free mounting on the side web 33 would also be possible.

The lower catwalk 35 of the central rail 30 protrudes between the two Catwalks 24, 25 of the body rail area. On the lower catwalk 35 is also a stop 39 to limit the pull-out movement of the center rail 30 provided from the body rail 20. By lifting the middle rail 30, the stop 39 can be attached to the body rail 20 Castor can be lifted.

The load is transferred between the middle rail and the body rail over the rollers 1, 2. The roller 1 of the body rail rolls down in the directed track 11 on the underside of the lower runway 35 of the central rail 30 from, the track 11 laterally from the connecting web 36 and the fold 37 is limited, which causes lateral guidance of the roller 1 becomes. The rear roller 2 of the center rail 30 is in the retracted state and over a part of the extension section on the next upward career 12 at the top of the lower runway 25 of the Body rail 20. The raceway 12 is on the one hand through the fold 26, on the other hand limited by the gradation 29 in the lower catwalk, whereby a groove-shaped depression is formed in the lower catwalk 25, in which the Raceway 12 is arranged so that lateral guidance of the roller 2 causes becomes. A load change takes place in the course of the pull-out movement, followed by the roller 2 on the downward raceway 12 'on the underside of the upper one Catwalk 24 of the body rail is present. Since the game of roller 2 between the two catwalks 24, 25 is only slight, there is lateral guidance of the roller 2 still by the fold 26 and the gradation 29 in the lower Catwalk 25. Furthermore, the upper catwalk 24 also has a step 29 ' on, causing at least one-sided lateral guidance of the roller 2.

For load transfer between the pull-out rail 40 and the central rail 30 there are rollers 5, 6 provided between the upper runway 44 of the pull-out rail and the upper runway 34 of the middle rail and between the lower catwalk 45 of the pull-out rail and the upper catwalk 34 of the central rail roll. These rollers 5, 6 are in a carriage 13 in corresponding Recesses of the carriage floating and from each other spaced. Furthermore, 13 are in corresponding recesses in the carriage in vertical side walls guide rollers 7, 8 floating, the on the one hand between the side web 33 of the middle rail 30 and the side web 43 of the pull-out rail 40 and on the other hand between the side web 33 of the middle rail 30 and the vertical web 46 of the pull-out rail 30 and roll Guide the pull-out rail laterally opposite the central rail 30.

The driving roller 3 runs on the one hand on the underside of the lower catwalk the pull-out rail 40, on the other hand on the upper side of the upper runway 24 the body rail 20 and sets the synchronism of the rails 20, 30, 40th safe when pulling out or pushing in.

On the central rail 30 stops 50, 51 are further attached, which are the displacement limit the carriage 13.

To limit the insertion movement of the pull-out rail 40 there is a provided on the carriage 13 abutting stop 47. In the area of rear end 42 of the pull-out rail 40 is another, not visible in the figures Stop provided to limit the pull-out movement of the pull-out rail, the fully extended state at the rear of the Carriage 13 strikes.

The catwalks 24, 25 of the carcass rail 20 extend from the side catwalk 23 towards the extendable extendable on the pull-out rail Furniture part 16, d. H. The catwalks 25 are thus on the from the furniture body 9 remote side of the side bridge 23 of the body rail 20. The catwalks 44, 45 of the pull-out rail 40 extend from the one connecting the catwalks Side web 43 also in the direction of which can be fixed on the pull-out rail pull-out furniture part 16, d. H. the catwalks 44, 45 are on the side of the side web 43 of the pull-out rail remote from the furniture body 9 40th

The pull-out rail 40 and the middle rail 30 can advantageously already be connected to each other at the factory, while the middle rail 30 into the body rail 20 can be used or removed from this. Here is in the upper Catwalk 24 of the body rail in the area of the front end 21 of the body rail a recess 52 is provided which extends to the rear of the roller 1 of the body rail 20 extends. The distance between the end of the recess 42 and the roller 1 is larger than the diameter of the roller 2. On this, the roller 2 of the center rail 30 in the area between the two catwalks 24, 25 of the body rail 20 are threaded, as shown in Fig. 9 is shown. By lifting the center rail 30, the stop 39 be transferred over the roller 1.
