The support element is formed as a body rigidly connecting an upper support surface, a lower support surface and another support surface with one another. Each support element is pivotably mounted at a pivot axis at a guide element (3) e.g. groove-like channel, between the locking position and a release position. The support surfaces are arranged outside the guide element. The body is an injection molded plastic body or an integral metal or ceramic body.

Description

The present invention relates to a pull-out locking device for at least two furniture parts which can be pushed into and out of the furniture body, in particular drawers, wherein the pull-out locking device has at least one guide rail and a sequence of support elements displaceably mounted on an elongated guide element of the guide rail in its longitudinal direction, wherein each support element, seen in an operating position of the pull-out device, an upper support surface for abutment with a support member disposed adjacent thereto and a lower support surface for abutment with a support member arranged below below and at least one further support surface for abutment on above or below adjacent support element wherein each support element has a release position for abutment with its upper support surface on the adjacently disposed above support element and for contact with its lower support surface on the adjacently disposed below support member and wherein each support member has a locking position for engagement with its other support surface on above or below adjacent support member.

Pull-out devices are known in a variety of forms in the art. They serve to prevent additional pull-out furniture parts such as drawers can be pulled out of a furniture body, if already other correspondingly extendable furniture parts or drawers are pulled out of this furniture body. The aim is to prevent the furniture body from being accidentally out of balance or falling over when too many pull-out furniture parts or drawers have been pulled out of it. Usually, such Ausziehsperrvorrichtungen already block the withdrawal of other extendable furniture parts, if only a single extendable Furniture part is pulled out of the furniture body. Such Ausziehsperrvorrichtungen are eg from the DE 195 47 049 A1 known. There, the support elements are constructed in several parts. On the one hand, the support elements on rods which are slidably mounted in the guide element of the guide rail. On the rod-like parts of the support elements shown there are arranged on the other tiltable lever. These are also assigned to the support element. In this multi-part construction of the support elements, the lower support surface is located on an additional roller, which is arranged on the rod-shaped part of the support element and thus is also assigned to the respective support element. The upper support surface and the other support surface are located on the pivoting lever.

In the DE 195 47 049 A1 The extension of a support element in the direction parallel to the longitudinal direction of the guide element corresponds to the extension of a drawer in the same direction.

Also in the EP 2 128 364 A1 the respective support elements of the pull-out device are constructed in several parts. Each support element has a so-called monobloc element, which has the upper and the lower support surface. In addition, each support element additionally but also one, opposite the monobloc element pivotable hook, on which there is the further support surface for the blocking position.

The object of the invention is to improve generic Ausziehsperrvorrichtungen in the sense of the simplest possible structure.

This is achieved by forming each support element as one, the upper support surface and the lower support surface and the further support surface in rigidly interconnecting body and that each support member is pivotally mounted about a pivot axis between the locking position and the release position on the guide member and all Support surfaces are arranged outside the guide element.

A basic idea of the invention is thus to use, instead of the previous multi-part construction, supporting elements which, as a rigid body, have at least both the upper support surface and the lower support surface and also the further support surface. These three support surfaces are thus formed rigidly in the form of a body, said body so that the respective support member is pivotally mounted about a pivot axis between the locking position and the release position on the guide member. In terms of the formation of the support elements as a single inherently rigid body, the support elements can also be referred to as pawls or blocking body accordingly. Of course, these inventive, rigid in itself, the support elements forming body can also have more than just support surfaces. The fact that all support surfaces are arranged outside the guide element, makes it possible to provide a relatively large stroke between locking position and release position by correspondingly large training of the support surfaces and correspondingly large distances between the support surfaces.

For clarification it should be mentioned that the guide rail is that component which as such is usually fastened directly in the furniture carcass, and insofar carries the remaining parts of the pull-out device. It includes or contributes in addition to the guide element, for example, also upper and lower stops, as they are mentioned below. In addition, the guide rail usually in addition to the guide element and mounting tabs with which the guide rail can be attached to the furniture body. In addition, on the guide rail also, as shown in the embodiments, a lock may be provided for blocking the entire Ausziehsperrvorrichtung. The guide element, however, is only the part of the guide rail on or in which the support elements are actually slidably mounted. The guide element can be designed, for example, as a corresponding undercut groove, that is to say channel-like. In these embodiments, it is particularly advantageous if each support element has a, preferably T-shaped, guide pin for slidable mounting on, preferably by means of engagement in the guide element of the guide rail. The guide pin is conveniently also a part of the inherently rigid Body, which forms the respective support element. If the guide element is designed as a rod, the support elements according to the invention can have, for example, corresponding guide rings or the like, which surround the guide element annularly.

The guide element is advantageously in the operating position of the pull-out device in the vertical direction extends longitudinally. His longitudinal direction thus runs conveniently parallel to the vertical. The pivot axes about which the respective support elements are pivotable, preferably extend orthogonal to the longitudinal direction of the guide element. But it is also possible that the guide element in the operating position of the pull-out device in the horizontal direction extends longitudinally or extends its longitudinal extent in said operating position at an angle between the vertical and the horizontal.

Particularly preferred forms of the design of the support element as a rigid body provide that each support element is designed as a, the lower support surface and the upper support surface and the other support surface, and preferably also the guide pin, in integrally interconnecting body. Again, more than the three support surfaces mentioned can be integrally integrated in the support element. Integral in this context means in particular that all parts of the support element consist of one and the same material and are fixed together as one piece. For the sake of completeness, it should be noted that the support elements may also be designed as a rigid body, if individual parts of the support element consist of mutually different materials or parts, but these parts are just fixed and rigidly interconnected.

Particularly preferred variants provide that each support element is designed as a one-piece, preferably injection-molded, plastic body or as a one-piece metal or ceramic body.

In order to bring a respective support element from its release position to its blocking position or vice versa, preferred embodiments of the invention provide that the pull-out locking device has release elements with which the support elements can be actuated or pivoted. Conveniently, at least one such triggering element is provided per extendable furniture part. Preferred embodiments of the interaction between the support element and the triggering element provide that each support element has a pivot arm arranged eccentrically with respect to its pivot axis for pivoting the support element about its pivot axis by means of a pivotable on the extendable furniture part, preferably peg-shaped, triggering element. It should be noted that triggering elements do not necessarily have to be pin-shaped, but may also have other shapes. Conveniently, these triggering elements at least cooperate with the eccentrically arranged pivot arms to pivot the respective support element between the release position and the blocking position and / or forth. The pivot arms may have recesses for receiving a particular peg-shaped release element for this purpose. But it is just as possible, to name just another example, that a peg-shaped extension is arranged on the pivot arm, which cooperates with a corresponding recess in the trigger element.

Preferred embodiments of a Ausziehsperrvorrichtung invention further provide that, preferably exactly, an ausziehbaren furniture part can be moved, preferably pin-shaped, trigger element between two adjacently arranged support elements, whereby the trigger element forcing one of the support elements forcibly from its release position into its blocking position or vice versa swings. In particular, in this context, it is advantageous if the upper support surface and the lower support surface in each case have a run-on slope for a, preferably pin-shaped, release element arranged on the extendable furniture part.

Furthermore, it is advantageous if the displaceability of the support elements along the guide element between two stops is limited, with all remaining or other support elements are fixed in position relative to the attacks when or after at least one of the support elements has been arranged in its blocking position , This is especially true when all other extendable furniture parts or drawers should already be blocked when a single pull-out furniture part or a single drawer has moved out of the furniture body. If you want to allow the withdrawal of more than one pull-out furniture part of the furniture body, the fixation of the remaining support elements between the stops only when a corresponding number of support elements are arranged in their locked position. This can be easily established by appropriate arrangements of the attacks in coordination with the dimensioning of the support elements.

In terms of the simplest possible structure, it is advantageous if all supporting elements of the pull-out device have an identical shape. The support elements should give a certain grid. In particular, in preferred embodiments, all support elements in their release position, seen in the longitudinal direction of the guide element, the same distance between their respective upper and lower support surface. The corresponding extension of the associated drawers or extendable furniture parts in the longitudinal direction of the guide element should then be an integer multiple of the mentioned longitudinal extension of a support element arranged in its release position. Preferred embodiments provide true integer multiples, ie integral multiples greater than or equal to 2. The said integer multiple can also be 1.

A first group of Ausziehsperrvorrichtungen provides that only guide elements according to the invention, preferably with mutually identical shape, are arranged on the guide element. On the other hand, other embodiments of the invention provide that between the support elements according to the invention intermediate elements are arranged, which also along the guide element are displaceable. This is particularly useful if the dimensioning of the support elements, a relatively fine grid is given, but in some areas relatively large drawers are available. In order to reduce the number of support elements required in such Ausziehsperrvorrichtungen, some support elements can then be replaced by appropriate intermediate elements. These intermediate elements can then be simpler in their construction. For example, they do not have to be mounted pivotably on the guide element like the support elements about a pivot axis. It may be at the intermediate elements to simple rod-like structures or the like. However, the intermediate element should fit in the predetermined by the dimensioning of the support elements grid. In this sense, preferred embodiments provide that between at least two support elements at least one guide element in the longitudinal direction slidably mounted intermediate member is arranged, wherein the longitudinal extension of the intermediate element, seen in the longitudinal direction of the guide element, a, preferably true, integer multiple of the longitudinal extent of one in his Release position arranged support element is.

Further features and details of preferred embodiments of the invention will be explained with reference to the description of the figures. Show it:

• Fig. 1 to 16 a first embodiment of a Ausziehsperrvorrichtung invention, in which only the support elements according to the invention are slidably mounted on the guide element;
• FIGS. 17 to 32 a second embodiment according to the invention, in which two of the support elements of the first embodiment are replaced by an intermediate element and
• Fig. 33 a side view of a single support member of the two aforementioned embodiments.

For the first embodiment in the Fig. 1 to 16 four different operating states are shown. There are four figures for each operating state. In the Fig. 1 to 4 an operating state is shown in which the not shown here extendable furniture parts or drawers are completely inserted into the furniture body, also not shown. There are thus all support elements 5 still in their release position in which one of the furniture parts, not shown here, can be pulled out of the furniture body. The Fig. 5 to 8 and the Fig. 9 to 12 show two operating states occurring immediately after each other, when in the course of pulling out one of the movable furniture parts, here the upper, has been pivoted from the furniture body of one of the support elements 5 already in its locked position. The Fig. 13 to 16 then still show the situation in which the trigger element 12 is completely pulled out of the array of support members 5 and in the blocking position located support member 5 prevents the withdrawal of the second furniture part. At the pull-out furniture parts or drawers, which are not shown here, at least one trigger element carrier 21 is attached in each case. The direction in which the furniture parts, not shown, are pulled out of the furniture body is indicated by the arrow 28. The re-insertion of the furniture parts or drawers in the furniture carcass takes place in the opposite direction. The illustrated embodiment of a pull-out device 1 is equipped with two trigger element carriers 21 and corresponding trigger elements 12 in the variant shown. In the illustrated variant, the pull-out device thus serves for two pull-out furniture parts or drawers. In accordance with flatter drawers the same Ausziehsperrvorrichtung 1 but also in more such as three drawers, then be used with a corresponding number of trigger elements 12. The drawer heights must ultimately only fit the grid dimension of the support elements 5. The grid dimension is predetermined by the longitudinal extent 19 of the support elements 5 in their release position, in which, in the example shown, the lower support surface 7 of the respective upper support element 5 is arranged on the upper support surface 6 of the respective lower adjacent support element 5.

In the Fig. 3 . 7 . 11 and 15 each of the two cooperating with the upper trigger element 12 supporting elements 5 are drawn out. The Fig. 4 . 8th . 12 and 16 With reference to FIGS Fig. 3 . 7 . 11 and 15 in each case the views from the opposite side, ie from the direction of the guide element. 3

The illustrated pull-out locking device 1 has a guide rail 2. This in turn has a mounting plate 24, with which the Ausziehsperrvorrichtung 1 is attached to the furniture body, not shown here. Furthermore, the guide rail 2, the guide element 3, on which the support elements 5 are slidably mounted in the longitudinal direction 4 of the guide element 3. In the exemplary embodiment shown, the longitudinal direction 4 of the guide element 3 runs parallel to the vertical. The guide element 3 is executed in the embodiment shown as a groove-shaped channel with marginal undercuts. Each support element has a guide pin 10, with which the respective support element 5 is displaceably mounted in the guide element 3 or engages in the guide element 3. Fig. 33 shows a side view of the support member 5 in the well to recognize that the guide pin 10 of this embodiment is each T-head-shaped. The guided directly in the guide member 3 head plate 29 of the guide pin 10 is formed in the embodiment shown so that it limits the pivot angle of the respective support member 5 about its respective pivot axis 9 by corresponding stop in the groove-shaped guide member 3. But this does not necessarily have to be the case.

The support elements 5 used in the first embodiment are all formed identically. In the exemplary embodiment shown, it is an integral body whose parts are rigidly interconnected. In this respect, you can also call the support elements 5 as integral pawls. The support elements 5 are displaceable along the guide element 3 or its longitudinal direction 4, wherein the displaceability is, however, limited by the upper stop 16 and the lower stop 15. It would in principle be conceivable to permanently fix the distance between the upper and lower stops 16 and 15 to a level which corresponds to the longitudinal extension 20 of one of the support elements 5 in the locked position plus the sum of the longitudinal extensions 19 of the remaining support elements 5 in the release position equivalent. This would make it possible that by pulling out a drawer or a pull-out furniture part of the support elements 5 is brought into the blocking position, which is prevented by the stops 15 and 16 then that still another support member 5 is pivoted from the release position to the blocking position can be, which once a drawer or a pull-out furniture part is pulled out, the withdrawal of further pull-out furniture parts is prevented.

In the illustrated embodiment, it is a slightly more expensive construction. The lower stop 15 is fixedly secured to the guide rail 2, while the upper stop 16 itself can be pushed up against a spring, not shown here, a piece far up until it abuts a not shown above lying further stop and thereby one, in This position no longer displaceable stop for the top support member 5 forms. This somewhat more complex variant of the design of the upper stop 16 was chosen here in order to make the shown pull-out locking device 1 lockable. For this purpose, the lock 22 is provided with its rotary latch 23. In the locking position of the lock 22 prevents the trained as an eccentric rotary latch 23 that the stop 16 of the in Fig. 2 shown position can be moved upwards. As a result, all support elements 5 are held in their release position, pivoting in the locked position is not possible in this locked state of the pull-out device 1, which none of the here not shown, but one of the trigger element carrier 21 each assignable extendable furniture parts from the furniture body in this closed position of the castle can be pulled out.

If the rotary latch 23 is rotated by appropriate actuation of the lock 22 in such a way that it releases the upper stop 16, then this can be pushed up a little when one of the support elements 5 is pivoted out of the release position into the blocking position. The upper stop 16 then reaches its end or stop position when said support element 5 is fully pivoted into its blocking position. Then it is in the first embodiment shown no longer possible to pivot more support elements 5 from its release position to its blocking position, which prevents more than one drawer or more than one extendable furniture part can be pulled out of the body. Generally speaking, the distance between the stops 15 and 16 must be matched to the size of the support elements 5 that only the desired maximum number of support elements 5 can be brought into the blocking position before the remaining support elements are blocked in their release position unverschwenkbar and not in the blocking position can be pivoted.

In 3 and 4 are the two herausgegriffen support elements 5 in their release position. The triggering element 12, which is connected via the trigger element carrier 21 to the extendable furniture part, not shown here, is designed as a journal in the embodiment shown and is located in the Fig. 1 to 4 in Ausziehrichtung 28 seen behind the two in the 3 and 4 drawn support elements 5. More precisely, the trigger element 12 is arranged in this position in a receiving recess 25 of the eccentric with respect to the pivot axis 9 on the support member 5 integrally formed pivot arm 11. The upper support member 5 is supported with its lower support surface 7 in this release position on the upper support surface 6 of the underlying support element 5 from. The further support surface 8, which is located in the embodiment shown at the end remote from the respective pivot axis 9 end of the pivot arm 11 is not active in the release position.

A minimal embodiment of support elements 5 according to the invention would provide that each support element has exactly three support surfaces, namely an upper support surface 6, a lower support surface 7 and a further support surface 8. In the embodiment shown, this is realized consuming. Thus, in the illustrated variant on the pivot arm 11 of the support element 5, two further support surfaces 8 and 8 'are provided. The one of the two further support surfaces 8 is supported in the blocking position shown in the following figures on an additional support surface 27 of the other support member 5, while the second further support surface 8 'on the upper support surface 6 of the underlying Supporting element 5 is supported. However, this is of course only an example, which should show that not only exactly three but also more than three support surfaces per support element 5 are possible according to the invention. There are many different embodiments for this purpose. In any case, it is important that the longitudinal extent 20 of the supporting element 5 in the longitudinal direction 4 in the blocking position is greater than the longitudinal extent 19 of the supporting element 5 in the longitudinal direction 4 in its release position.

Another variant, which is executed in the embodiment shown but need not necessarily be provided, is that the trigger element 12 is movably mounted relative to the trigger element carrier 21 and thus to the extendable furniture part, not shown here. In the embodiment shown, this is realized by the guide pin 12 is pivotally mounted in the trigger element carrier 21. Other embodiments would be a displaceable mounting of the trigger element 12 in a corresponding guide groove or the like. The variants with a movable triggering element 12 can be used in order to enable as low a movement as possible movement of the overall system of the pull-out device 1. In simple variants, however, the corresponding triggering elements 12 can also be fastened fixedly to the triggering element carrier 21 or to the extendable furniture part.

The Fig. 1 to 4 show, as I said, the position in which the two furniture parts not shown here are completely inserted into the furniture body, not shown here. In this situation, all support elements 5 are in their release position. The 3 and 4 show the position of the trigger element 12 in the withdrawal direction 28 behind the superimposed upper and lower support surfaces 6 and 7 of the superposed support elements 5. Now one of the two movable furniture parts, here the upper, pulled out in the direction 28 from the furniture body, so meets the trigger element By further pulling out the movable furniture part and thus the trigger element 12 in the direction 28, one of the support elements 5, here the top, from its release position about the pivot axis 9 in the, in the Fig. 5 to 8 illustrated blocking position pivoted. In the locked position, in particular according to the FIGS. 7 and 8 is the upper support member 5 then no longer with its lower support surface 7 on the upper support surface 6 of which is still located in the release position support member 5 on. In the in Fig. 7 shown blocking position is rather the upper support member 5 supported with its further support surface 8 on the additional support surface 27 and with its second further support surface 8 'on the upper support surface 6 of the underlying support element 5. As a result, as already mentioned, the longitudinal extension 20 of the uppermost support element 5 is achieved. The upper stop 16 has been pushed upon pivoting of said support member 5 by the corresponding difference between the longitudinal extensions 20 and 19 upwards into its final position. Thus, it is no longer possible that another support member 5 is pivoted from its release position into the blocking position. As a result, it is prevented in the exemplary embodiment shown that the lower drawer, not shown here, together with the lower trigger element carrier 21 can be moved out of the fully inserted position. To leave the position according to the Fig. 5 to 8 Now, the trigger element 12 to be able to pull out of the receiving recess 25 of the support member 5 is pivoted at a further train on the movable furniture part in the withdrawal 28, the trigger element 12 in the trigger element carrier 21, whereby it is possible, the trigger element 12 on the drive lug 26 over in the pull-28th to move on. This situation is in the Fig. 9 to 12 shown. Subsequently, the trigger element 12 leaves the receiving recess 25 completely. The pull-out furniture part is then as far as desired, so pulled out a maximum to its open end position. Meanwhile, brought into the blocking position support member 5 blocks the displacement of the remaining support elements 5 in the longitudinal direction 4 of the guide element 3 between the stops 15 and 16 so that no further drawer can be pulled out in the pull-out 28 of the pull-out device 1. This is only possible again when the displaceable previously moved furniture part in the insertion direction, ie opposite direction 28 has been pushed back so far that the trigger element 12 by corresponding stop on the pivot arm 11, the support member 5 again in its release position according to Fig. 1 to 4 has panned.

In the FIGS. 17 to 32 Now, a second embodiment according to the invention is shown, in which not only support elements 5 are arranged exclusively on the guide element 3. In this embodiment, a part of the support elements 5 is replaced by an intermediate element 17. Although the intermediate element 17 is displaceable in the longitudinal direction 4 on the guide element 3, but unlike the support elements 5 is not pivotable. Corresponding intermediate elements 17 can be used as a substitute for supporting elements 5 wherever no triggering elements 12 are extended and retracted. It is thus possible to bridge with the intermediate elements 17 corresponding spaces between extendable furniture parts or drawers. At the upper end, the intermediate element 17 has a support surface, which cooperates with the lower support surface 7 of the overlying support element 5 and corresponds in shape with this. At its lower end, the intermediate element 17 has a corresponding lower support surface, which cooperates with the upper support surface 6 of the underlying support element 5 and is formed correspondingly corresponding. The longitudinal extension 18 of the intermediate element 17 should fit into the predetermined by the support elements 5 pitch. It is preferably provided that the longitudinal extension 18 of the intermediate element 17 in the longitudinal direction 4 corresponds to the longitudinal extension 19 of a support element 5 in the same direction, or a true integer multiple, that is an integer multiple greater than or equal to 2.

By replacing in their functionality at this point unnecessary support elements 5 by corresponding intermediate elements 17 changes nothing in the operation of the pull-out device 1. The second embodiment works technically exactly as it has already been described for the first embodiment. In the FIGS. 17 to 32 became the Fig. 1 to 16 corresponding representations used, the situation according to Fig. 17 according to the situation Fig. 1 , according to the situation Fig. 18 according to the situation Fig. 2 etc. corresponds. In general, it is therefore sufficient, apart from the differences between the embodiments described with respect to the technical description of the second embodiment to refer to the technical description of the first embodiment.
