Way (s) for carrying out the invention

Based on FIGS. 1 to 4 For example, an embodiment of the first aspect of the invention can be explained. In FIG. 1 is a drawer extension 1 diagrammatically shown obliquely from above. The drawer extension is arranged between the side walls of a piece of furniture in which the drawer is to be arranged. The furniture may be any piece of furniture, in particular a cabinet or a chest of drawers and in particular a composable system furniture. In FIG. 1 only one side wall 20 of the furniture or the furniture body is shown to simplify the drawing. In particular, it is a kitchen furniture, for example, a kitchen furniture in which a refuse bag holder is housed and in which the drawer extension is disposed above the refuse bag holder.

The drawer 1 has a drawer 4 and two side drawer guides 2 and 3. The drawer guides each comprise an elongated body 12 and 13, which is fastened to the respective furniture side wall to form the furniture-proof guide for the drawer. Thus, the drawer slide 2 is attached to the indicated side wall 20 of the furniture, preferably screwed. And the drawer guide 3 is fixed to the side wall, not shown, preferably screwed, which is opposite to the side wall 20.

The drawer guides 2, 3 must be in the correct, for the drawer 4 suitable distance from each other, so that the drawer fits between the drawer slides and is guided in these extendable. Especially with system furniture, such as kitchen furniture, side walls of different thickness or wall thickness are used. For example, wall thicknesses of 16mm or 19mm are common. Depending on the wall thickness of the side walls, the drawer guides should be selected or spacers should be selected in order to be able to mount the drawer slides in the appropriate distance for the drawer.

In the example shown the FIGS. 1 and 2 the drawer guides 2 and 3 are each provided with a spacer 32 and 33, which increases the thickness of the body 12 of the drawer slide 2 and the thickness of the body 13 of the drawer slide 3. With the spacers 32 and 33 thus a smaller wall thickness of the side walls of the furniture is compensated, so that the distance of the drawer slides from each other is suitable for a piece of furniture with low wall thicknesses. It can also be provided with a spacer, only one of the drawer guides, if the furniture has a larger wall thickness on one side wall and a smaller wall thickness on the other side wall. The spacers 32 and 33 are executed in this example substantially congruent with a large side surface of the respective body 12 and 13, which side surface comes to lie to the side wall of the furniture. Instead of only one spacer 32 and 33 could also be provided a plurality of smaller spacers and these could cover only a portion of the large side surface of the respective body 12 and 13 respectively.

FIG. 3 shows an embodiment of the drawer guides a drawer slide according to the invention in a position in which the spacers 32 and 33 have been placed on the respective body 12 and 13 in a position in which they are easily detachable from the body. Previously, the spacers have been swung away from the respective body, so they are no longer in the in FIG. 1 represented position in which they rest against the large surface of the body. The spacer 32 is removably attached to the body 12 by being integrally connected to the body 12 via a destructible connection 8. Similarly, the spacer 33 is integrally connected via the destructible connection 9 with the body 13. Preferably, the drawer guides with the respective body 12 and 13 and the associated spacers 32 and 33 integrally formed of plastic and the releasable connection 8 and 9 is formed in each case by a film hinge of the plastic. The detachment of the spacer from the body can be done by tearing off, in which the film hinge breaks or by cutting the film hinge with a knife or a pair of scissors.

Due to the detachable connection, preferably the detachable one-piece compound made of plastic, the spacer is initially always provided on the body or is pre-assembled by the manufacturer and can not be lost or incorrectly installed.

It can be provided that the respective spacer part of the drawer guide has a pin or a differently shaped shape, with which it engages in the body of the drawer guide fitting position in a recess of the body to the respective Spacer frictionally and / or positively in its pre-assembled position in which it increases the thickness of the drawer slide to keep. In the in FIG. 3 illustrated embodiment, two pins 14 are provided at each spacer part, which engage in pin holes 15 in the respective body, when the respective spacer coplanar aligned fitting is positioned on the body, as in the FIGS. 1 and 2 shown. Thus, the respective spacer is held on the body fitting and / or non-positively and the spacer does not automatically take the position of FIG. 3 but must first be swung away from the body. To facilitate this indentations can be provided, in which a tool between the body and the associated spacer can engage to open the positive connection, so that the position of FIG. 3 can be achieved. In this example indentations 16 are provided above the pins 14.

The respective drawer slide 2 or 3 is thus preferably in the configuration according to FIG. 2 shipped, in which the thickness of the body 12 and 13 of the drawer guide is increased by the spacer 32, and 33, respectively, and thus a configuration for a furniture with a small wall thickness is given. If the drawer guide to be used in a furniture with higher wall thickness, the respective spacer 32 and 33 in the position of FIG. 3 or another pivoted position in which the respective spacer 32, 33 is no longer coplanar with the body and the connection 8 or 9 is destroyed, so that the spacer is detached from the body and can be disposed of. The drawer guide is then executed without the spacer, as in FIG. 4 shown, and is then mounted on the respective side wall without the spacer, which is compensated with the less thick body, the higher wall thickness of the furniture.

The spacer preferably has through holes 10 ', which are aligned coplanar fitting position of the spacer on the respective body with its mounting holes 10, which mounting holes are provided for screwing the drawer slide to the furniture.

In the example shown, a spacer on a narrow side of the body is provided on each body of the drawer slide. This is a preferred example. But it could also be provided on both narrow sides of the respective body spacers, which are then in particular correspondingly shorter, so that they do not come to lie one above the other in coplanar position. It does not have the whole large area of the body, which is the furniture side wall, covered over. Preferably, however, the areas of this surface are covered, on which the fastening screws for the attachment of the respective drawer guides are passed, so that the drawer guides abut the furniture evenly. Instead of or in addition to the arrangement shown on a narrow side of the body, a single or multiple spacers may also be provided on one or both longitudinal sides of the body. Also in these cases, the respective spacer or the spacers are detachably connected to the body, preferably also in each case also integrally connected to the body, preferably also via a film hinge made of plastic body and spacer or made of plastic drawer slide.

In FIG. 4 Furthermore, the guide 22 for the drawer in the body 12 of the drawer guide is visible in perspective view. In FIG. 5 showing a vertical section through the drawer slide 2 and a part of the drawer 4, it can be seen that the drawer has an angled on its front guide member 24 which engages the guide 22 and held therein by the guide limiter 25 becomes. Guide blocks 26 limit the lateral play of the drawer-side guide member 24 in the guide 22 and counteract tilting of the drawer in the two drawer guides 2 and 3.

In the FIGS. 1 to 7 is a further aspect of the invention in an exemplary form, which can be combined with the previously discussed aspect of adaptation to the wall thickness of the furniture, as shown, but which can also be carried out by itself.

This aspect relates to a drawer extension for the drawer, so that it can not be pulled out of the drawer guides of the drawer extension unintentionally, resulting in an unwanted dropping of the drawer. According to the invention, such an extension limit is designed so that a solid first stop is formed on the drawer in the rear region and is provided on the drawer guide integral with this a resiliently receding into the body second stop. When the drawer is pulled out, the first and second stops come into contact when the drawer has reached its maximum proper extension length at which it remains in the guides. This contact between the first drawer side stop and the second drawer guide side stop blocks the drawer when reaching the maximum safe extension length. The resilient design of the second stop, which recoils when overcoming the spring force in the body, so that the first stop can slide past the second stop, but it allows by overcoming the spring force, the drawer still completely pull out of the drawer slide, if desired.

In FIG. 3 the second stop 40 can be seen in both drawer guides 2 and 3, and in FIG. 1 the drawer guide 3 faces Side of the drawer 4, the fixed first stop 42 can be seen, which comes when pulling the drawer with the stopper 40 into contact and thus forms the extension limit. In the FIGS. 6 and 7 this is shown for two positions of the drawer 4 in a plan view, in which the drawer is shown cut horizontally, so that their lateral upper limits in the FIGS. 6 and 7 omitted and the view of the top of the drawer slides 2 and 3 is free. In FIG. 6 the drawer is shown in its retracted position, in FIG. 7 in the position that in normal use corresponds to the maximum excerpt. In this extended position, the stop 42 of the drawer is in contact with the stop 40 and the drawer is not further pulled out. In the figures, however, it can be seen that the second stop 40 is held resiliently in the drawer guides. If the pull-out force on the drawer 4 in the position of FIG. 7 increased so far that the stop 40 resiliently recedes, the drawer is released and can be completely pulled out of the guides. Due to the resilient arrangement of the second stop 40, this can also be avoided when pushing in the previously completely removed drawer into the drawer guides and the drawer can be returned to the position of use. The spring-back of the second stop is facilitated by the rear side of the drawer is angled.

The resilient arrangement of the second stop 40 in the respective drawer slide 2 and 3 is effected by a respective leaf spring 41 integrally formed with the body 12 and 13. This carries the second stop 40 or forms this by their shape, as shown in the figures , in particular approximately in the middle of the longitudinal extent of the leaf spring 41. The drawer slide 2 or 3 is made in one piece with the leaf spring 41 and the second stop 40 made of plastic, which allows a particularly simple and cost-effective production, since no additional parts must be manufactured and assembled.

While preferred embodiments of the invention are described in the present application, it is to be understood that the invention is not limited thereto and may be embodied otherwise within the scope of the following claims.
