Description

drawer pull guide

technical field

The invention relates to a drawer pulling guiding device, which comprises:

- body rails to be fastened to the body of the furniture,

- A drawer rail to be fastened to the drawer, the drawer rail being movably supported relative to the main body rail between a closed position and an open position.

Background technique

Such adjustment devices for drawer extension guides are known in the prior art and are proposed, for example, in document WO 2008/131466 A1. Adjusting devices of the type mentioned at the beginning serve a variety of purposes. Firstly, they serve as stops for panel or furniture doors; moreover, these adjusting devices have elastic elements in order to be able to dampen the closing movement, for example in the closed position of a drawer or door. Furthermore, for example to increase operating comfort, furniture is often provided with ejection devices by means of which movable furniture parts can be ejected from their closed end position/closed position in or on the furniture body. Especially in the case of handleless, movable furniture parts, these ejection devices are often constructed in such a way that they are actuatable by pressing the movable furniture parts such as drawers beyond the closed position and make them automatically move towards the open position direction to move. A certain amount of play must be allowed for the movable furniture part in its closed position for this triggering, which can be achieved by means of elastic elements located in the adjusting device. These adjusting devices are often fastened directly to the furniture body or to the movable furniture part. However, this involves additional work steps when assembling the furniture, which should be saved if the adjusting device is located directly on the drawer extension guide.

The adjusting device forms an adjustable stop for a movable furniture part, for example a drawer, which stop is preloaded by a spring. If the stop is adjusted inwards or outwards in the adjusting devices shown in the published prior art, the spring force of the spring element located therein is also adjusted at the same time. In other words: the more the stop is turned inward, the higher the spring force of the spring element behind it. The more the stop is turned outward, the less spring force it will have. If the adjusting device is fastened on the left and right sides of the furniture body containing the drawers, then after installation both stops must be adjusted to the position of the closed position of the drawers. If the adjustment device on the right is now screwed in more than the adjustment device on the opposite side, for example, in the direction of the furniture body, the spring pretension on the right is higher than that on the opposite left. This can cause uneven seam appearance between the individual drawers, or uneven gap size between the drawers and the body of the furniture. Furthermore, due to the different spring forces of the clamping in the drawer, damage can also result in the longer term.

Contents of the invention

The object of the present invention is to avoid the aforementioned disadvantages and to provide an improved drawer extension guide with an installed adjusting device compared to the prior art.

According to the invention, this object is achieved in that an adjustment device is provided on the drawer extension guide, preferably on the body rail, by means of which adjustment device the position of the closed position of the drawer rail relative to the body rail can be variably adjusted. .

It should be possible to be able to adjust the position of the closed position of a movable furniture part, such as a drawer, without at the same time changing the pretension of the elastic element in the adjustment device. Furthermore, steps such as additional drilling of the furniture body or marking fastening points on the furniture body should be avoided by fastening the adjusting device directly to the rail system of the drawer extension guide.

The stop for the movable furniture part is already present after installation of the guides required for this without further work steps and can be put into use after adjustment.

If, for example, at least two adjusting devices are used for a movable furniture part, the spring force of the spring elements in each adjusting device should be equally high. Only the position of the stop should be changed, not the spring force.

If the adjusting device is provided on the adapter, which is preferably connected to the body rail via at least one releasable fastening device, then the adjusting device for the movable furniture part does not require further steps after the installation of the drawer pull-out guide The case already exists and can be put into service after adjustment. In the case of an already existing drawer system, the adjusting device can be retrofitted on the rail system via an adapter, since the adapter provided for this has a fastening device which can be mounted on the rail system.

If, for example, at least two adjusting devices are used for a movable furniture part, the spring force of the spring elements in each adjusting device is equally high. Only the position of the stop is changed, not the spring force. In other words, it has proven to be advantageous if the spring force of the spring element on the unloaded slide is independent of the adjustment between the sleeve and the main body.

Further details and advantages of the invention emerge from the dependent claims.

detailed description

FIG. 1 shows a drawer pulling guide device 10 , which includes a main body rail 11 and a drawer rail 12 . The drawer extension guide 10 is fastened to the furniture body 20 via a fastening region on the body rail, which is not visible in FIG. 1 . In the completely assembled state of the furniture, a panel 23 , which is omitted in FIG. 1 for better illustration, is placed on the front region of the drawer extension guide 10 . Located on the body rail 11 is an adapter 13 on which the adjustment device 1 is positioned.

FIG. 2 shows a detail of the drawer extension 10 shown in FIG. 1 . The adjustment device 1 is mounted on an adapter 13 which in turn is connected to the main body rail 11 of the drawer extension guide 10 . The adjusting device 1 comprises a base body 3 which contains a slide 6 . The slider 6 , which is formed as an elongated circular body, is mounted in the base body 3 so that it can rotate about the axis of rotation Z .

FIG. 3 a shows an arrangement comprising a drawer 21 , a furniture body 20 , a panel 23 and an adjustment device 1 . The adjustment device 1 is mounted on an adapter plate 13 which is connected to the body rail 11 via at least one fastening device 14 . The panel 23 of the drawer 21 is in the closed position. This closed position is delimited by a stop formed by the end face of the slide 6 . In other words, the adjusting device 1 has an adjustable stop, which is preferably acted upon by at least one spring element 5 . The location of the closed position of the movable furniture part, for example the drawer 21, is defined by this adjustable stop. It can be seen in FIG. 3 a that the distance X between the panel 23 and the front edge of the adapter 13 results. If the front edge of the panel 23 is viewed in relation to the front edge of the furniture body 20 , it can be seen that the panel protrudes beyond the furniture body.

FIG. 3 b shows how the panel 23 is adjusted relative to the furniture body 20 . The distance marked as distance X1 between the front panel 23 and the adapter plate 13 is now smaller than the distance X shown in FIG. 3 a . This is achieved in that the drawer 21 has a front panel 23 , in which the slide 6 of the adjusting device 1 forms a stop on the end face, which abuts against the side of the front panel 23 in the closed position of the drawer rail 12 . On the back side, wherein the closed position of the drawer 21 can be adjusted relative to the furniture body 20 by rotating the slider 6 .

FIG. 4 shows a converter 13 which preferably has at least one releasable fastening device 14 with which the adapter 13 can be connected to the main rail 11 . This can be achieved, for example, via a screw connection or a plug-in connection or a groove and tenon. The base body 3 is located on the adapter 13 . This basic body 3 contains a thread 8 which corresponds to the thread of the sleeve 4 . The elastic element 5 is inserted into the sleeve 4 . Since the slide 6 is inserted into the sleeve 4 , the spring is pretensioned by the shaping of the sleeve 4 or slide 6 . Receptacles 9 for tools, preferably slots or cross-recesses, are formed on the end faces of the slide 6 .

FIG. 5 shows a detailed exploded view of the adjustment device 1 . This adjusting device comprises a base body 3 with a thread 8 and a sleeve 4 with a corresponding mating thread 8 which is then screwed into the base body 3 . The rotation stop 15a is located inside the sleeve, in this case configured as a groove. The twist stoppers 15b of the slider 6 fit into these grooves. The cooperation of the torsion locks 15 a , 15 b ensures that the slide 6 is mounted axially movable along its axis of rotation Z in the sleeve 4 against rotation. The limiting device 16 prevents the slide 6 from slipping out of the sleeve 4 in the installed state of the slide 6 in the sleeve 4 .

FIG. 6 a shows the adjustment device 1 in a state of maximum outward adjustment. The slide 6 can be rotated about the axis of rotation Z at the receptacle 9 of the slide 6 by means of a suitable tool, such as a screwdriver or an Allen key. As an alternative, it is also possible for the slide 6 to have at least one protrusion or groove on its housing for manual twisting without tools. It can be seen that the spring receptacle 7 placed on the rear bottom of the sleeve 4 holds the spring element 5 in position. A slide 6 which is movable linearly in the adjusting device 1 is located on the opposite side. It can also be seen here that the slide 6 is prestressed along the axis of rotation Z by at least one spring element 5 situated between the slide 6 and the sleeve 4 and protrudes at least partially from the sleeve 4 and the base body 3 . A possible slipping of the slider 6 out of the sleeve 4 , which may be caused by the elastic element 5 , is prevented by at least one limiting device 16 . As shown in FIG. 6 a or can also be seen in FIG. 5 , this limiting device can be designed, for example, as a snap-in device. The snap-in devices have the advantage that they considerably simplify the assembly of the adjusting device 1 . The snap-in devices shown in FIG. 6 a , which are designed as hooks on the slider 6 , engage in corresponding surfaces on the sleeve 4 and thus prevent the spring element 5 from being fully unloaded. The slide 6 is thus permanently pretensioned by the spring element 5 .

FIG. 6 b shows a sectional view of the adjusting device 1 , which has been adjusted in an intermediate region. By rotation about the axis of rotation Z, the sleeve 4 is screwed into the base body 3 via the thread 8 either by means of a tool or manually. The torsion lock 15 , which is not visible in FIG. 6 b but is shown in FIG. 5 , prevents the slider 6 from being able to rotate in the sleeve 4 . Every rotational movement exerted on the slide 6 is thus transmitted to the sleeve 4 . The distance between the spring receptacle 7 and the slide 6 does not change here. As a result, the elastic force of the elastic element 5 also remains constant when the slider 6 is adjusted relative to the base body 3. The adjustment between cartridge 4 and base body 3 is irrelevant.

FIG. 6 c shows the adjusting device 1 , which is now screwed in as far as it will go. The sleeve 4 now sits flush on the end side with the end face of the base body 3 . Only the slider 6 protrudes from the configuration of the individual fittings of the adjusting device 1 . If the superimposed illustrations of FIGS. 6 a , 6 b and 6 c are now compared, the adjustment range Y can be seen. The adjustment range Y enables depth adjustment of the drawer 21 in the furniture body 20 . This makes it possible to calibrate the drawers 21 relative to each other or to the furniture body 20 . In order to be able to carry out this depth adjustment of the drawer 21 , the drawer 21 must be opened and the adjusting device 1 must then be accessible on the underside of the drawer 21 . As can be seen in FIG. 3 b , the distance X1 , or in other words the position of the closed position, is adjusted by manual or tool adjustment. The adjustment here takes place from the front in an accessible area on the furniture body 20 . The drawer 21 does not have to be disassembled for adjustment.

FIG. 7 a shows the adjusting device 1 , in which the end face of the slide 6 now lies flush with the end face of the sleeve 4 . This shows the maximum compression depth of the elastic element 5 when eg the panel 23 is pressed against the stop of the slider 6 and the pressure exceeds the spring force of the elastic element 5 .

Figure 7b shows the arrangement comprising the elastic element 5 and the slide 6 in the unloaded state. No external influences act on the adjusting device 1 , for example via the front panel 23 of the drawer 21 . The elastic element 5 thus springs outwards to a maximum extent and is limited only by the corresponding surface of the delimiting device 16 a attached to the slider 6 or the delimiting device 16 b attached to the sleeve 4 . If one compares FIGS. 7 a and 7 b , the spring travel F can be seen. This spring travel F is used, for example, in an ejection device (not visible in the drawing). To increase operating comfort or in the case of drawers without handles it is provided that the drawer 21 has an ejection device acting in the direction of the open position, which can be triggered by overpressing the spring travel F of the elastic element 5 on the slide 6 .

Furthermore, the drawer 21 can have a spring-loaded pull-in device (not visible in the drawing) acting in the direction of the closed position. This pull-in device assists in pulling the drawer 21 into the closed position. This spring-loaded pull-in device must not have a spring force greater than the spring force of the spring element 5 of the adjusting device 1 in the region immediately before reaching the closed position. A defined location of the closed position then occurs only when the spring force of the spring element 5 counteracts the spring force of the spring-loaded retracting device. If the spring force of the spring element 5 is too weak, the spring-loaded pull-in device will pull the drawer inwards past the just-adjusted closed position, and thus the closed position cannot be adjusted.
