Description

The present invention relates to a cabinet drawer with arranged on one side guide means comprising a pull-out element, which by the guide means, consisting of stacked Linear guides which can be fastened to a holding part inserted in a cabinet are guided from an inserted position to a solid one Position and vice versa is displaced, and on which pullout storage slots or the like can be attached.

Such cabinet drawer are e.g. from DE 42 36 182 A known. Often they are in Used cabinets, on which one only has the possibility on one side, the To attach guide means, the available space, for example in cupboards of kitchens, should be used optimally.

In these known cabinet extensions arranged on one side Guiding means, the guide means consist in many cases of ball guides, be designed as simple statements or as telescopic extensions can. The assembly of these ball guides must be very accurate, as the Tolerances are very small. As a result, the assembly effort is relatively large.

The object of the present invention is now a Cabinet drawer with guide means arranged on one side, in which the mounting on a holding part used in a cabinet is simplified. Furthermore, the pullout element should be in a simple manner in the guide means can be used and removed from these again.

According to the invention, the solution of this object is achieved in that a linear guide, which is fastened to the holding part, with holding elements equipped, in which the pull-out element can be suspended and that one Part of the other linear guide with at least one peg-shaped Guide piece is provided in the inserted state of the pull-out element in the linear guides in a slot-shaped recess of the other Part of the other linear guide protrudes. When hanging the pull-out element in the holding elements of a linear guide is the at least a pin-shaped guide piece in the slot-shaped recess of the other Linear guide inserted. Depending on the length of this pin-shaped guide piece and the height of the slot-shaped recess is the tolerance, within which the one linear guide is to be fastened to the holding part, relative big, without the leadership quality suffers.

In order to achieve that the pull-out element completely out of the Cabinet can be pulled out, this is at least one cone-shaped Guide piece on a sliding relative to the holding part of the other Linear guide arranged.

For optimum guidance and a long extension path of the pull-out element To achieve, it is advantageous that two pin-shaped guide pieces are attached to a first profile of the other linear guide, which first profile is displaceable along a second profile, that on the holding part or is attached to the extension element, while a slot-shaped recess containing third profile attached to the extension part or on the holding part is. By this arrangement, a telescopic extension is obtained.

A simple structure of the other linear guide is obtained by that the second profile is attached to the holding part, the first profile longitudinally displaceable held on the second profile and the third profile with an area is provided, which is designed as a U-profile, which is the slot-shaped recess forms and is arranged on the extension element, in which the peg-shaped Protruding guide pieces. The third profile can thus be a component be used of the pull-out element.

To avoid that the peg-shaped guide pieces from the can extend slot-shaped recess is at the end portions respectively a stopper piece is provided, by which the displacement path is limited becomes.

A further advantageous embodiment of the invention is that the holding elements of a linear guide of two headed Bolts are formed on the extendable element of a linear guide are fixed, and that on the pull-out element openings with slots are attached, with which the pull-out element to the headed Bolt can be suspended. This will make a very simple hooking of the Pulling element reaches the one linear guide.

To avoid that the pull-out element in the suspended state in which a linear guide can jump when moving, are Locking means provided with which the hanging is lockable.

A particularly simple construction of the locking means is characterized achieved by each one of the extractable element of the a linear guide attached resilient tab are formed on the sprung End of a web is attached, which in a corresponding recess can be latched on the pull-out element. When inserting the pull-out element These tabs spring back, latches when the correct position is reached the web by the spring action in the recess, to solve this Locking the resilient tabs can be easily pushed back become.

Advantageously, the respective resilient tab with the web and in each case a bolt together via a fastening element on the extendable Element of a linear guide attached. This results in a simplified Manufacturing.

To hang and unhook the pull-out element in To simplify the guides as possible, it is advantageous that the one linear guide with the holding elements above the other linear guide with the slot-shaped recess for the peg-shaped guide pieces on Holding part is attached.

An embodiment of the invention is described below with reference to attached drawing explained in more detail by way of example.

Fig. 7 is a view of the pullout element with the guides, wherein a part of the other linear guide is omitted for clarity.

From Fig. 1, the cabinet drawer 1 can be seen, which consists of a pull-out element 2 is formed, which by an upper linear guide 3 and a lower linear guide 4 is held extendable in a holding part 5. This Holding part 5 may be a side wall of a cabinet element, for example a Kitchen device, be, this holding part 5 can also be a side part of a be in a cabinet element accommodated displaceable component, which are moved transversely to the extension direction of the extension element 2 can, and in particular applies to corner cabinets.

The pull-out element 2 is constructed as a flat frame and sets Comprised of an upper profile 6 and a lower profile 7, over two side profiles 8 and 9 are connected to each other. On these side profiles 8 and 9 hooks 10 are attached to which the storage compartments, not shown, for example, in the form of baskets, hung in a known manner can be.

On the upper linear guide 3 are holding elements 11 and locking means 12 arranged through which the pull-out element 2 at the top Linear guide 3 is held, as will be described later in detail.

In Fig. 2, the cabinet drawer with fully extended pull-out element 2 shown. As can be seen in particular from Fig. 3, in which Presentation the pull-out element 2 is taken away, there is the upper Linear guide 3 of a first rail 13 which is fixed to the holding part 5, a second rail 14, which guided guided displaceably in the first rail is, as well as a third rail 15, which in turn led in the second Rail is slidably mounted. The holding elements 11 and the locking means 12 for holding the pull-out element 2 are at this third Rail 15 is arranged. In a known manner are between the individual Rails 13, 14 and 15 ball guides provided. Of course could be used instead of ball guides and other known guides become.

The lower linear guide 4 has a first profile 16 which is longitudinal a second profile 17 guided slidably mounted, which second profile 17 is attached to the holding part 5. Again, the guides between the first profile 16 and the second profile 17 may be formed as ball guides. Again, instead of the ball guides other known guides be used. As can be seen in particular from Fig. 3, are the first Profile 16 two vertically arranged, peg-shaped guide pieces 20 and 21st attached. These two vertical pin-shaped guide pieces 20 and 21st protrude, as will be described in detail later, into a slot-shaped Recess 18 which is mounted in the lower profile 7 of the pull-out element 2 is, which lower profile 7 thus as a third profile for the lower linear guide. 4 serves, according to the third rail 15 of the upper linear guide. 3

As can be seen from Fig. 4, the lower profile 7 of the extension element 2 an area which is formed as a U-profile 19, which the slit-shaped recess 18 forms. In this slot-shaped recess 18th protrude into the two pin-shaped guide pieces 20 and 21, when the pull-out element 2 is in the inserted state, as shown in Fig. 4 is. These pin-shaped guide pieces 20 and 21 can in a known Be equipped with a role.

The peg-shaped guide pieces 20 and 21 are, as already mentioned, mounted on the first profile 16, with respect to the second profile 17, which is attached to the holding part 5, guided longitudinally displaceable over ball guides is.

In particular, the region of the first profile 16, with the peg-shaped Guide pieces 20 and 21 is provided by a cover covered, which cover as an extension of the one Leg of the U-profile 19 is formed.

From this Fig. 4 is also the upper linear guide 3 with its first Rail 13, the second rail 14 and the third rail 15 can be seen on which third rail 15, the holding elements 11 and the locking means 12th are attached.

The pull-out element 2 can be removed from the linear guides 3 and 4 be solved by the locking means 12, as later will be described, the pull-out element 2 can be raised until the Holding elements 11 are released, as also described later is, the pull-out element 2 is slightly inclined away from the holding part 5 and can from the pin-shaped guide pieces 20 and 21 are extended. The Insertion of the extension element 2 in the linear guides 3 and 4 takes place in reverse order of the previously described steps.

From this it can be seen that the dimensional tolerances, within which in particular, the upper linear guide 3 has to be mounted on the holding part 5, can be relatively large, it must only be ensured that the cone-shaped Guide pieces 20 and 21 deep enough in the slot-shaped recess 18 protrude and thus the leadership is guaranteed.

Of course, it would also be conceivable that the cone-shaped Guide pieces 20, 21 attached to the lower profile 7 of the pull-out element 2 would be, the slot-shaped recess 18 could then be provided on the first profile 16 be, (this profile 16 could be provided with a U-profile, the open at the top), the first profile 16 could be the same with respect to be the second profile 17 to be displaced. Of course, others would be synonymous Guides conceivable as ball guides, such as sliding guides.

As can be seen from FIGS. 5 and 6, there is a respective retaining element 11, which attaches to the third rail 15 of the upper linear guide 3 are provided with heads 22 bolt 23. These bolts 23 are over a Pin 24 connected to the third rail 15 of the upper linear guide 3, for example by riveting. The upper profile 6 of the pull-out element 2 is in the region of these holding elements 11 each with an opening 25 with a provided subsequent slot. The breakthrough 25 is designed so large that the head 22 can be passed while upwards directed slot has a width which is substantially equal to the diameter of the bolt 23 corresponds. To mount the pull-out element 2 in the upper linear guide 3, the heads 22 of the support members 11 through the Openings 25, which are mounted in the side profile 9, introduced, then the pull-out element 2 lowered, the respective slot passes behind the head 22 of the holding element 11 in the region of the bolt 23 and then supported on it.

Together with the bolt 23 of the holding element 11 is a respective Locking means 12 on the third rail 15 of the upper linear guide. 3 attached. This locking means 12 consists of a resilient tab 26, which is directed upward, attached to the resilient end of a web 27 is. This web 27 latches when inserted into the upper linear guide 3 Extracting element in a corresponding recess 28, which on upper profile 6 of the extension element 2 is provided, as this particular in Fig. 5 can be seen. To unhook the pull-out element 2 is the upper Part 29 of the resilient tab 26 pushed back, the web 27 is the recess 28 free, the pull-out element 2 can be raised until the head 22nd of the holding element 11 enters the region of the opening 25, the pull-out element 2 can be removed from the support member 11.

An easy way to manufacture and especially for Assembly of the holding elements 11 and the locking means 12 is characterized achieved that holding member 11 and locking means 12 in one piece be formed from an elastic material. With the one pin 24 can then in a simple manner, both the retaining element 11 as well as the locking means 12 in one pass on the third rail 15 of the upper linear guide 3 are attached.

In the view according to FIG. 7 it can be seen that the slot-shaped Recess 18, through the U-profile 19 in the lower profile 7 of the pull-out element 2 is formed, both sides with a respective stop piece 30 and 31st is provided. This avoids that the peg-shaped guide pieces 20 and 21 when pulling out the pull-out element 2 or during insertion of the extension element 2 extend out of the slot-shaped recess 18 can. This ensures that the guidance is always optimal.

In this embodiment, the pull-out element 2 with the two Linear guides 3 and 4 mounted on the right side on the holding part 5. The same Components can also be used for a left-side mounting on the holding part 5 become. The lower linear guide 4 can be moved unchanged to the left side be, in the upper linear guide, the tabs 26 with Bridge 27 with the pin 23 with heads 22 to the respective pin 24 by 180 ° be rotated in order to be used on the left side. The unchanged Pull-out element 2 can then be rotated and hung on the left side become. As a result, the production and storage is simplified since only one kind of excerpts must be present.

It would also be conceivable to interchange the two linear guides 3 and 4, so that the holding elements 11 and the locking means 12 on the lower linear guide would be attached while the peg-shaped guide pieces 20 would be located in the upper linear guide.

With this inventive arrangement is a simple and stable guidance of a lateral extension element 2 obtained, which is very can be easily mounted on a side holding part 5, and which in easiest way unhooked from the linear guides 3 and 4 and again can be hung.
