The support rail is secured to the holder part along the axial direction of the support rail using a releasable locking mechanism. An Independent claim is included for a drawer.

Description

The invention relates to a pull-out guide set according to the preamble of the claim 1. Such a pull-out guide set is usually used for fastening of a drawer or moving floor on a side wall of a fixed one Furniture body used.

It is during the life of a piece of furniture with a pull-out guide often required to disassemble the piece of furniture by weight and their size are portable to the individual parts in another place to build together. Especially when one piece of furniture has multiple pull-out guide sets it is expedient if the disassembly into individual parts is as effective as possible can be carried out without the stability by the simple disassembly of the reassembled piece of furniture suffers.

From the generic DE 83 33 251 U1 is a pull-out guide for Drawers known, in which the drawer in the pull-out rails in the furniture body mounted pull-out guide set can be hooked in and removed again. To make it easier to hang and remove the drawer is on everyone Pull-out guide set provided a locking device by means of which the pull-out rail can be held on the mounting rail. Here is the mounting rail firmly screwed to the furniture body, while the one that can be moved on the mounting rail Pull-out rail detachable in the front and rear area with a drawer connected is. The locking device consists of a mounted on the pull-out rail Pawl that snap down into a recess in the mounting rail can. Thus, the drawer can be removed from the furniture body while the pull-out guide set remains in the furniture body.

The known pull-out guide set is not free from disadvantages. On the one hand, remains the heavy pull-out guide set, usually made of sheet metal Furniture body that is very heavy compared to the drawer. The disassembly of the Furniture in individual parts therefore results in an extremely uneven weight distribution of the individual parts. On the other hand, the previously known locking device from Security aspect poor, since the pivoted jack is not sufficient is secured and can easily be operated unintentionally. If the jack accidentally is pulled out, the pull-out rail can freely from the furniture body slide out and injure people or damage objects. If takes into account that the furniture body in particular is bulky and heavy, can Transport of the furniture body such an unintentional unlocking of the locking device enter easily.

DE 42 42 717 shows a pull-out guide set for drawers, in which the Pull-out guide has a pull-out rail, a mounting rail and a central rail. The mounting rails are mounted on mounting brackets, which are mounted on the furniture body are. Hooks are formed on the mounting brackets, into which the mounting rails can be inserted are. Furthermore, the mounting rails are held on spring-loaded locking parts, wherein the locking parts are pressed in and then to release the mounting rail the mounting rails can be removed. A fixation of the pull-out rail and the Middle rail is not provided.

US 5 292 198 shows a release mechanism for a pull-out guide in the a support bracket a hook is arranged in a recess of a mounting rail intervenes. To release the mounting rail, the hook is pushed in and the drawer with the pull-out guide can be removed. Another way of locking a pull-out guide is shown in US 4,465,324, which is only a pull-out rail and includes a mounting rail. The mounting rail is on a mounting bracket detachably fixed by stops. With such a definition, one can not completely avoid certain game.

It is therefore an object of the present invention to a pull-out guide set create that is easy to assemble and disassemble a piece of furniture in just a few Individual components with even weight distribution possible. Furthermore, the pull-out guide set should protect against incorrect operation and be inexpensive producible components can be assembled.

This task is performed with a pull-out guide set with the features of the claim 1 solved. According to the invention, a pull-out guide set is provided, especially for attaching a drawer or moving floor to one

Side wall of a fixed furniture body, with a mounting rail that with a is firmly connectable with a furniture body holding part, and at least a track that is slidably mounted to the mounting rail, and that with a Push floor or other push part. is connectable, the mounting rail by means of a releasable locking mechanism on the holding part in the direction the axis of the mounting rail can be locked. This training enables easy Assembly and disassembly of the pull-out guide set, during disassembly only the holding part firmly attached to the furniture body remains, while the pull-out guide set together with the moving floor, drawer or the like can be removed. The weight of a piece of furniture becomes like this evenly distributed on the individual parts, the rails of the pull-out guide set on the moving floor etc. because of the smaller size and the simpler Manageability pose a lower security risk.

According to a preferred embodiment of the invention, the locking mechanism the mounting rail on the holding part perpendicular in a first direction lockable to the axis of the mounting rail. This training ensures you The pull-out guide set holds securely even in one load direction. The mounting rail on the holding part is preferably additionally in a second direction lockable, the second direction being inclined to the first direction and extends perpendicular to the axis of the mounting rail. This will make the Push floor or drawer in all possible horizontal and vertical directions kept safe.

Receives a locking mechanism that is simple and inexpensive to manufacture one, if this has a sliding locking element that with the Holding part cooperates. The locking element can advantageously be a means for locking the holding part in the first and second directions.

According to the invention is the unlocked state of the locking mechanism at least one running rail is held essentially fixed on the mounting rail, so that when you remove the pull-out guide from the furniture body Movement of the running rail or running rails is essentially prevented. A slight movement of the running rails up to about 4 cm means in this context still "essentially fixed" because of a movement of this magnitude is still relatively harmless from a security perspective. However, is preferred a maximum play of the running rail (s) of less than 1 cm is desired.

In an advantageous embodiment of the invention is a locking element provided that has a latching device with a on a moving floor or drawer attachable locking element cooperates and the locking element is movable into a released position by the latching element. This Training ensures that the locking element is not actuated unintentionally is, but is only adjustable by targeted actuation of a locking element.

The locking element is preferably designed to be movable and arrives in one first position not in engagement with the locking element and locked in one second position with the locking element. This will be an assembly aid provided that the locking element is slidably received on a guide member and can be locked in the first and second positions. This can the fitter hear and feel whether the desired position of the locking element has been reached is.

An easy-to-produce pull-out guide set is obtained when the locking element by means of a guide element attached to the mounting rail is slidably mounted between the mounting rail and the guide element. It can the guide element can be plugged onto the mounting rail and by means of a locking device be held on the mounting rail. The manufacture of the pull-out guide set can also be automated over long distances.

If the above locking element has at least two locking tongues has, which at least partially encompass the holding part in the locked state, can be achieved by simply moving the locking element Interlocking in several. Get direction. A simple guide to the Locking element is obtained when this is along one on the mounting rail formed recess is slidably disposed.

The pull-out guide set according to the invention can be produced inexpensively, if the mounting rail and the intended running rail (s) are made of metal are and the components of the locking mechanism made of plastic are.

According to the invention, a drawer is also provided, with a sliding floor, which is held on both sides by a pull-out guide, a front panel, Side walls and a rear wall, the drawer two according to the invention Pull-out guide sets.

The pull-out guide set shown in Fig. 1 is used to attach a moving floor 1 of a drawer on a furniture body, not shown. Therefor are on both sides of the moving floor 1 partially made of metal connecting elements 3 each attached to a slide rail 40 of a pull-out guide. A mounting rail 9 of the pull-out guide is made of metal with a holding part 2 connected, which is screwed into a side wall of a furniture body. By doing illustrated embodiment, two rails 39 and 40 are provided, so that the sliding floor 1 can be pulled over the front surface of the furniture body can. It is also possible to provide only one running rail 39 if the displacement path can be reduced.

The push floor 1 is held on each side on three connecting elements 3, which partially reach under the moving floor 1. On the fasteners 3, side wall elements 4 are attached by means of latching or other holding devices, which lie on the inside of the sliding floor 1. At the back of the moving floor 1, a rear wall 8 is provided which is connected to the moving floor 1 is screwed and locked on both sides with a connecting element 3 is. At the front of the moving floor 1 is one not shown in Fig. 1 Front panel 38 attached to two front connectors 3.

On the underside of the moving floor 1, a guide part 5 is screwed into the moving floor and engages in corresponding openings with pins provided on two ends of the moving floor 1. The guide member 5 has a curved shape and has a central section bent towards the center of the moving floor 1. A It is not possible to mount the middle section facing outwards, otherwise the middle section would abut the holding part 2. In the middle section of the Guide part 5, a slot 7 is provided in which a guide head 25 of a locking element 6 is included.

A mounting rail 9 is detachably fastened in the holding part 2. In the rear part of the holding part 2 a protruding nose 14 is formed for this purpose, into which the rear end the mounting rail 9 can be inserted (Fig. 5). Through the bottom of the Holding part 2 and the nose 14 is the mounting rail 9 in the rear area both after supported above and below. So that the mounting rail 9 when inserted in the holding part 2 is brought into the correct position are embossments on the holding part and projections are provided which the support rail 9 in the lateral direction to lead. Furthermore, a stop is embossed in the holding part 2, which the insertion path limited. The holding part 2 faces towards the moving floor with a slant provided with an upward curved edge on which there is also an inclined edge Edge of the five-sided mounting rail 9 rests.

17 is the pull-out guide with the running rails 39 and 40 and the mounting rail 9 shown in cross section. There are three between each of the rails cylindrical rolling elements 41, so that the rails 39 and 40 on the mounting rail 9 are movably guided and are supported perpendicular to the direction of movement. On the running rail 40 is the section of the connecting element made of metal 3 attached to X.

A locking mechanism is provided in the front area of the holding part 2, with which the mounting rail 9 can be fixed to the holding part 2. The locking mechanism comprises a locking element 10 which is slidable on the Support rail 9 is mounted. For this purpose, a guide element 31 is provided, which on the mounting rail 9 is attached and with the mounting rail 9 a guide channel formed.

The locking element 10 is shown in FIGS. 6A to 6D. A central web 17 connects two end sections of the locking element 10. The central web is with an expansion 22 provided with the guide channel on the guide element 31 interacts and for easy locking or a certain stiffness the shift provides. The one facing the front of the moving floor 1 Section has a locking projection 19 which has an inclined surface and is held on the central web 17 with a certain elasticity. On this Side is also a retaining lug 23, which is integrally formed on an end portion 20 which also has a rib-shaped stop 21. Between Mittelsteg 17 and retaining lug 23 is a gap which is dimensioned so that a part the end edge of the holding part 2 can be inserted into the gap. The introduction is facilitated by the beveled shape of the retaining lug 23 on the front.

A guide foot 18 is provided on the opposite side of the central web 17, the provided in the installed state along a in the mounting rail 9 Recess is slidable, the mounting rail 9 in the approximately V-shaped Area engages on the guide foot 18. At the outer lower end of the guide foot is a projection in the locked position of the locking element 10 the support rail 9, which supports the locking element 10 (Fig. 2). Furthermore, a locking tongue 11 is formed on the central web 17, which by a in the support rail 9 formed opening 15 engages and in a recess of the holding part 2 can partially encompass this. The locking tongue 11 has a stepped Shape, since the opening 15 and the recess of the holding part 2 in plan view easily are staggered. The recess and the opening 15 are there each on the obliquely upward edge of the holding part 2 or the mounting rail 9 formed so that the locking tongue 11, the mounting rail 9 and the holding part 2 engages around the respective edges and in a direction perpendicular to the Sloping surface locked. The holding lug 23, however, engages on the horizontal surface an embossing on the holding part 2, so that a locking in vertical direction is guaranteed.

7A to 7E, several views of the locking element 6 are shown. The locking element is essentially T-shaped and has at the bottom of the T a downwardly protruding grip element 24, which has a lateral projection having. The latching element 6 can be located in the guide element on the grip element 24 5 move by hand. At a central section of the locking element 6 a guide head 25 is provided which, in the manner of a latching element, into the slot 7 of the guide element 5 can engage. The guide head 25 and the slot 7 are arranged offset to the central axis of the locking element 6, so that the installation the locking element can only take place in the correctly aligned position. Next a slot 26 and a projection 27 are arranged on the guide head 25. By the slot 26, the projection 27 is held elastically in the lateral direction, so that the locking element 6 in a displacement in the guide element 5 in two end positions can be locked, which is why in the guide element 5 a recess for the projection 27 is formed.

The locking element 6 also has a left locking projection 28 and a right one Locking projection 30. The two locking projections 28 and 30 are symmetrical, so that the locking element on both the right and left side of the moving floor 1 can be used. The locking projections 28 and 30 each have locking bevels, which are designed in shape and inclination so that they with the locking projections 19 can cooperate on the locking element 10. Furthermore, on the Detent element 6 is formed a second handle element 29.

Various views of the guide element 31 are shown in FIGS. 8A to 8D. The guide element 31 has a central guide channel 32, in which the middle web 17 of the locking element 10 slidably received can be. Ribs projecting inwards on the guide channel 32 provided so that the locking element at least in the assembled state is partially encompassed from all sides. On both sides of the guide channel 32 recordings 33 and 34 are provided, in each of which one end of an inclined Edge of the mounting rail 9 is receivable. There is a projection in the receptacle 34 36 formed in a corresponding recess on the mounting rail 9 can intervene to lock the guide element 31 on the mounting rail 9. Furthermore, stops 37 are formed on the guide element 31, which make a movement limit the locking element 6 in a locking process described below.

The locking mechanism is described below. In the shown in Fig. 3 Position, the mounting rail 9 is firmly locked with the holding part 2. Therefor engage the locking tongue 11 and the retaining lug 23 on the outside of the holding part 2 and clamp the mounting rail 9 against the holding part 2. As the locking tongue 11 and attack the retaining lug 23 on differently inclined surfaces is the Support rail 9 secured perpendicular to its rail axis in several directions. In In the direction of the rail axis there is an upwardly projecting stop on the Holding part 2 embossed with the movement of the mounting rail 9 in the longitudinal direction limited to a minimal game.

To open the locking mechanism, the locking element 6 is opened Drawer with the locking projections 28 and 30 to the locking element 10 moves until an inclined surface of a locking projection 28 or 30 in the following Close the drawer on the inclined surface of the locking projection 19 slides along the locking element 10 and upwards due to the elasticity is pushed away. Then the locking projection 28 or 30 snaps behind Locking projection 19 on the locking element 10. The locking element 6 is now firmly connected to the locking element 10. In the course of the snapping described the locking projection 28 or 30 has the locking element 10 over the Pulling projection 19 is pulled outward by an amount and thus releases the locking mechanism (Fig. 4). In this position, the retaining tab 23 and the locking tongue 11 no longer the holding part 2, so that the mounting rail 9 is raised can and can be removed to the front via the stop on the holding part 2 is.

Below are the individual steps for removing and inserting the Drawer described in more detail.

The drawer with the moving floor 1 is in the installed state in the position shown in Fig. 9. The front panel 38 is located on the stop 21 of the Locking element 10 on and the locking element 6 is in the guide element 5th picked up and hanging freely on the underside of the moving floor.

For the removal of the drawer, the drawer is initially not shown in FIG. 10 furniture cabinet shown pulled out. 10 is the pull-out guide with the rails 39 and 40 only shown schematically on the right side. The However, rails 39 and 40 are always on both sides next to the Sliding floor 1, even if this is due to the better clarity in FIG. 9 to 16 is not shown.

To release the locking mechanism, will be brief as above described the two locking elements 6 on the underside of the sliding floor 1 after moved outside until they lock in their outer position. The locking projections 28 and 30 are in the pull-out direction to the right and left locking element 10 (Fig. 11).

The drawer is then pushed in again until the locking projections 28 and 30 each with a locking projection 19 on a locking element 10 lock (Fig. 12), whereby an audible locking noise is generated for the fitter. in the In the course of the engagement, the locking element 10 has a displacement in the longitudinal direction experience and the locking between the holding part 2 and the mounting rail 9 released, so that the mounting rail 9 is no longer on the holding part 2 by the locking element 10 is locked. Then the drawer with the runners 39 and 40 raised a little way and over the stop on the holding part 2 removed to the outside.

The rails 39 and 40 and the mounting rail 9 are through the locking mechanism fixed to each other and cannot be moved towards each other. there stabilizes a friction roller, not shown, mounted on the running rail 39 Fixation, which otherwise only for a smooth movement of the rails 39th and 40 cares. When removing the drawer, it may be that the slide rail 39 or 40 protrudes over the rear wall 8 of the drawer to the rear. To avoid this, the length and position of the rails 39 and 40 can be so be chosen that this when the locking mechanism is in the locked position close with the rear wall 8 of the drawer.

The drawer is inserted in the reverse order. First of all the unit consisting of drawer and pull-out guide is inserted into the furniture body and inserted until the mounting rail 9 comes under the nose 14 and on the rear stop of the holding part 2 comes to rest while the mounting rail 9 sets off on the holding part 2 and by the front stop on the Holding part 2 is blocked in the pull-out direction.

The drawer is then pulled vigorously outwards so that the locking connection between the elastic locking projections 28 and 30 with the respective elastic Latching projections 19 of the two locking elements 10 are released (Fig. 14).

Then the locking elements 6 are moved inwards on both sides of the sliding floor, until they lock in their inner position (Fig. 15).

Then the drawer with the front panel 38 in the furniture body inserted, the inside of the front panel 38 against the stops 21 of the two locking elements 10 bumps (Fig. 16). The locking elements 10 pressed inward and moved to the locked position so that the Locking tongue 11 and the holding lug 23 encompass the holding part 2 and the mounting rail 9, so that the mounting rail 9 is firmly locked on the holding part 2.

Alternatively, the locking mechanism can be in the position shown in FIG. 13 can also be solved in that the locking elements 6 manually to the center of the drawer be moved there. Then the drawer can simply be closed, the front panel 38 on the stops 21 of the two locking elements 10 abuts and the locking elements 10 in the locked position shifts.
