Description

The present invention relates to a pull-out guide according to the preamble of claim 1.

Pull-out guides of the above-mentioned type are known in a multitude of embodiments in the prior art. They serve to mount furniture parts, such as e.g. drawers, pull-out larders, other push-in and pull-out units, in a furniture body in such a manner that they are able to be pulled out from the furniture body and pushed therein again. Upon pushing in and pulling out of the furniture parts, the rails of the pull-out guide are pushed into one another and pulled out of one another respectively. The retraction mechanism usually serves to automatically pull the furniture part fully into the furniture body at the end of the push-in motion, in order to ensure that the furniture parts reliably reach their fully pushed-in position. Examples of such pull-out guides with retraction mechanism are e.g. shown in EP 2 174 570 Bl. In the prior art, the retraction mechanism is attached to the body rail, above and/or below the latter. This is also provided in such a manner in the embodiments of EP 2 174 570 Bl.

The use of pull-out guides of the mentioned type known in the above-mentioned prior art becomes problematic when very shallow furniture parts or drawers are to be arranged in the furniture body. The arrangement, provided in the prior art, of the retraction mechanism on the body rail limits the desired shallow type of construction.

Prior art of the type in question, having at least two tilt slides, is known from WO 2010/143352 Al.

It is the object of the invention to make available an alternative variant of a pull-out guide of the above-mentioned type.

For this, it is proposed within the scope of the invention that the pull-out guide be constructed according to claim 1.

It is consequently not obligatory that the additional tilt slide according to the invention has to be part of the retraction mechanism. Rather it is provided according to the invention that the additional tilt slide is mounted in an additional guide so as to be displaceable and tiltable, wherein this additional guide is secured to a different rail of the pull-out guide than the body rail, e.g. to the central rail. The mounting on the central rail is of course only possible for the embodiments in which the pull-out guide has at least one central rail, wherein the drawer rail is mounted in the central rail so as to be displaceable in the retraction direction and counter to the retraction direction and the central rail together with the drawer rail is mounted in the body rail so as to be displaceable in the retraction direction and counter to the retraction direction. It is also possible with such embodiments that the retraction mechanism is arranged on a first side of a wall portion, extended vertically in an operating position of the pull-out guide, of the body rail and the drawer rail and also the central rail are arranged on a second side, opposite the first side, of this wall portion of the body rail.

Through the additional tilt slide, it is no longer obligatory for the tilt slide and the retraction mechanism to be arranged above or below the body rail. It hereby becomes possible for the pull-out guide, viewed in its operating position, to be constructed substantially smaller in its vertical extension, so that the pullout guide is also suitable for furniture parts which are correspondingly shallow in construction and which are able to be pulled out from the furniture body and pushed therein again. In other words, through the invention there is consequently a reduction in the installation space required for the pullout guide in a vertical direction. The furniture parts able to be pushed into the furniture body and pulled therefrom can, as known in the prior art, e.g. be drawers, pull-out larders however other push-in or pullout units too.

The retraction mechanism is preferably secured to the body rail and/or borne by the body rail. A particularly shallow design of the pull-out guide is possible when the retraction mechanism is arranged on a first side of the wall portion, extended vertically in an operating position of the pull-out guide, of the body rail and the drawer rail is arranged on a second side, opposite the first side, of this wall portion of the body rail. In other words, the retraction mechanism is preferably arranged on the body-rail side opposite the other rails of the pull-out guide.

Pull-out guides according to the invention can be in the form of what are known as standard extensions. With these only one body rail and a drawer rail displaceably mounted therein or thereon are present per pull-out guide. In this case, the drawer rail is directly mounted in the body rail in a displaceable manner. However it is preferably provided to construct pull-out guides according to the invention as what are known as full extensions. In these embodiments, the drawer rail is indirectly mounted in the body rail in a displaceable manner in that the central rail already mentioned above is additionally present between drawer rail and body rail. In other words, in such embodiments of the invention it is provided that the pull-out guide has at least one central rail, wherein the drawer rail is mounted in the central rail so as to be displaceable in the retraction direction and counter to the retraction direction and the central rail together with the drawer rail is mounted in the body rail so as to be displaceable in the retraction and counter to the retraction direction. In the case of such full extensions, the motion of the central rail and the drawer rail can be synchronized by synchronization devices known per se. For this purpose, one can revert to technologies of the prior art. The same applies to the question as to how the drawer rail is displaceably mounted in the body rail or in the central rail and how the central rail which may be present is displaceably mounted in the body rail. The most varied mounting styles known in the prior art can also be used for this purpose. For example rollers or ball bearings are conceivable. Simple plain bearings can be realized too, as in the prior art. However particularly preferably the pull-out guide is what is known as a roller extension, with which the individual rails are displaceably mounted against one another by means of rollers.

The body rail can be a component which is at first separate from the furniture body, which component is then secured in the furniture body using means known in the prior art. Equally however the body rail can also already be integrated in a furniture body or a part thereof. This too is covered by the concept of securing of the body rail to the furniture body. The same applies to the drawer rail. This too can be a rail which is separate at first and which is then secured to the furniture part. The drawer rail can however also be already integrated in the furniture part, such as e.g. the drawer, and consequently secured thereto.

The additional tilt slide can be displaceably and tiltably mounted in or on at least one elongate guideway of the or an additional guide, which guideway is bent or angular in at least one end region and is preferably slot-shaped or groove-shaped.

The tilt slide and the additional tilt slide can releasably engage one another in various ways. How this engagement takes place or is actually implemented can differ greatly. One could in general also refer to a fastening to one another or release from one another. It can be a mechanical, preferably friction-locked or form-locked, engagement. Equally one can however also use other connecting forces, such as e.g. a magnetic fastening to one another or an electrostatic fastening to one another or the like. The engagement term is therefore to be understood correspondingly broadly. However particularly preferably it is provided that the additional tilt slide has a first claw for releasable engagement with a claw of the tilt slide of the retraction mechanism and at least one second claw for releasable engagement with a contact element at one of the rails of the pull-out guide, preferably at the drawer rail. Here too the claw term or releasable engagement term are to be understood generally in accordance with the preceding explanations. A claw can actually be a fork-like embodiment which is provided for form-locked engagement with another claw or with the contact element at one of the rails. However other form-locked or friction-locked connections or connections based on other connection forces are also possible here too, such as e.g. also the electrostatic or magnetic releasable fastening to one another already mentioned above. In this context the claw term could therefore also be replaced generally speaking by a securing element and is thus to be understood generally.

With preferred embodiments of the additional tilt slide it is provided that the first claw and the second claw are arranged on facing sides of a pivot axis about which the additional tilt slide is pivotable. This pivot axis can be a pin or the like which is actually present physically, however also a notional pivot axis. With pull-out guides with tilt slide and additional tilt slide there are preferably different operating states. A first operating state can e.g. consist in the first claw of the additional tilt slide engaging the claw of the tilt slide of the retraction mechanism and the second claw of the additional tilt slide engaging the contact element at one of the rails of the pull-out guides. This operating state is preferably realised at the end of a retraction motion or at the start of a pulling out motion of the furniture part into or from the furniture body. In a second operating state it can then be provided that, preferably through tilting or pivoting of the claw of the tilt slide, the first claw of the additional tilt slide releases the claw of the tilt slide, while the second claw of the additional tilt slide however still engages the contact element at one of the rails of the pull-out guide. Upon pulling out of the furniture part from the furniture body, this second operating state preferably follows the first operating state. Vice versa, the two tilt slides are preferably located in the second operating state before the first operating state upon pushing in of the furniture part into the furniture body. In a third operating state it is then advantageously provided that both the first claw of the additional tilt slide is released from the claw of the tilt slide of the retraction mechanism and the second claw of the additional tilt slide is released from the contact element at one of the rails. This third operating state advantageously follows the second operating state upon pulling out of the furniture part from the furniture body. Upon pushing in of the furniture part into the furniture body from the fully pulled-out position, the tilt slides are vice-versa preferably located first of all in the third operating state, then in the second operating state and then in the first operating state.

With preferred embodiments it is provided that the tilt slide of the retraction mechanism reaches through a slit in the body rail. This slit is preferably arranged in a wall portion, extended vertically in an operating position of the pull-out guide, of the body rail. With a vertically extended wall portion of the body rail, the vertical extension of this wall portion is clearly greater than the thickness or material thickness of this wall portion. It is different with horizontally extended wall portions. There the horizontal extension is clearly greater than the thickness or material thickness of this wall portion.

The slit in the vertically extended wall portion of the body rail is advantageously extended longitudinally parallel to the retraction direction. In preferred embodiments, the tilt slide is mounted so as to be displaceable along this slit. However it must be pointed out with regard to the term slit that this is to be understood generally. One could also generally speak of a cut-out. This cut-out or the slit can have the most varied embodiments. In preferred embodiments the slit in the vertically extended wall portion of the body rail is however formed as a slot closed on both sides at its longitudinal ends.

In the event of a full extension it can, as mentioned, be provided that the retraction mechanism is arranged on a side or the first side of the wall portion, extended vertically in an operating position of the pull-out guide, of the body rail and the central rail is arranged on a second side, opposite the first side, of this wall portion of the body rail. In these embodiments with a central rail it is particularly preferably provided that an additional slit is arranged in a wall portion, extended vertically in an operating position of the pull-out guide, of the central rail and the tilt slide reaches through the additional slit. With the vertically extended wall portion of the central rail it is again thus that the vertical extension of this wall portion of the central rail is clearly greater than the thickness or material thickness of this wall portion.

It must also be mentioned with regard to the additional slit that the slit is generally a cut-out which can be designed and formed in different ways. Here too the slit term is therefore to be understood very generally in the sense of a cut-out. In preferred embodiments, the additional slit can be formed as a slot closed on both sides at its longitudinal ends. However it is equally conceivable that the additional slit is in the form of a slot closed on one side at one of its longitudinal ends and open at the opposite longitudinal end. The additional slit too is preferably extended longitudinally parallel to the retraction direction. The tilt slide can be mounted so as be displaceable along the additional slit. The tilt slide and the additional tilt slide can releasably engage with one another through the slit in the body rail and optionally also through the additional slit in the central rail.

To form the retraction mechanism per se one can in the basic construction substantially revert to different proposals from the prior art. The retraction mechanism preferably has at least one retraction spring for executing a retraction motion of the tilt slide and/or at least one damper for damping a or the retraction motion of the tilt slide. As known per se in the prior art, the tilt slide of the retraction mechanism can be displaceably and tiltably mounted in or on at least one elongate guideway of the retraction mechanism, which guideway is bent or angular in at least one end region. This at least one guideway can e.g. be slot-shaped or groove-shaped. However the guideway can also be in the form of guide rails or the like. Here too one can revert to all embodiments known in the prior art.

Further features and details of preferred embodiments of the invention are explained by way of example with reference to the description of the figures.

Figs. 1 to 18 show representations relating to an embodiment according to the invention in the form of a full extension.

In Figs. 1 and 2, the embodiment of the invention is shown in a state in which the drawer rail 3 of the pull-out guide 1 together with the central rail 11 is completely pushed or pulled into the body rail 2 in retraction direction 6. In Fig. 3, the drawer rail 3 and the central rail 11 are completely pulled out from the body rail 2 counter to the retraction direction 6. Fig. 4 shows the drawer rail 3 detached from the other rails and shows the contact element 23 which is here arranged at the drawer rail 3. Figs. 5 to 8 show different representations of the body rail 2 together with the retraction mechanism 4 without the other rails. Figs. 9 and 10 show the central rail 11 in two different views. Figs. 11 to 16 serve to show the manner of operation of the tilt slide 5 and of the additional tilt slide 19 in different operating states. The representations are partially sectioned in each case in order to be able to better show the tilt slides 5 and 19. Figs. 17 and 18 show the component parts of the retraction mechanism 4 in an exploded representation and additionally the additional guide 25 with the additional tilt slide 19 detached from the rails 2, 3 and 11 of the pull-out guide 1.

For the sake of completeness, reference is made to the fact that the figures show neither the furniture body nor the furniture part able to be pushed into the furniture body and pulled out therefrom by means of the pull-out guide 1. The arrangement and fastening of the pull-out guide 1 with its rails 2, 3 and 11 between furniture body and furniture part can be carried out as known per se. Customarily a pull-out guide 1 is arranged in each case on facing sides of the furniture part. Only one of these two pullout guides 1, which together appropriately mount a furniture part in the furniture body, is shown in each case in the figures shown here.

In the embodiment shown here it is a case of what is known as a roller pull-out guide 1, with which the rails 2, 3 and 11 are displaceably guided into one another by means of rollers 28. The drawer rail 3 is displaceably mounted in the central rail 11 and the central rail 11 is together with the drawer rail 3 displaceably mounted in the body rail 2. The pushing in and retraction takes place in retraction direction 6, the pulling out of the furniture part from the furniture body takes place in the direction counter to the retraction direction 6. The synchronization roller 33, visible particularly clearly in Fig. 9, together with the roller 28 arranged thereabove ensures the synchronization of the pull-out motion between drawer rail 3 and central rail 11, as is known per se and does not have to be explained in more detail. Solely for completeness, reference is made to the fact that pull-out guides 1 according to the invention do not of course necessarily have to be roller-based. Instead of the rollers 28 use can also be made of e.g. ball bearings or simple plain bearings, to name just a few examples. The synchronization of drawer rail 3 and central rail 11 can also be designed differently or be entirely absent.

The retraction mechanism 4 is secured to the body rail 2 and is thereby borne by the latter. As can be seen particularly well by means of figures 5 and 6, the retraction mechanism 4 is arranged on a first side 9 of the wall portion 8, vertically extended in the operating position of the pull-out guide 1, of the body rail 2. The drawer rail 3, as well as the central rail 11 in this embodiment, are located on a second side 10, opposite the first side 9, of this wall portion 8 of the body rail 2. The slit 7 is arranged in the wall portion 8, extended vertically in the operating position of the pull-out guide 1, of the body rail 2. In the shown embodiment the slit 7 is extended longitudinally parallel to the retraction direction 6. The tilt slide 5 of the retraction mechanism 4 reaches through the slit 7 in the body rail 2, as can be seen particularly clearly in figs. 5 and 7. It also emerges clearly from the comparison of these two figures that the tilt slide 5 is mounted so as to displaceable along the slit 7. The function of the claw 21 of the tilt slide 5 of the retraction mechanism 4 is explained in detail below. In the shown embodiment, the slit 7 is in the form of a slot bounded by the longitudinal ends 44.

The retraction mechanism 4 actuating the tilt slide 5 can differ greatly in design. The most varying variants are known for this in the prior art. In particular with reference to figs. 17 and 18, the retraction mechanism 4 used here has a first slide part 29 and a second slide part 30 displaceably mounted thereon in a direction parallel to the retraction direction 6. The first slide part 29 is secured or fixed to the first side 9 of the vertical wall portion 8 and thereby to the body rail 2. Pins 31 are arranged on the first slide part 29 and engage the guide grooves 32 of the second slide part 30. The displaceable mounting of the second slide part 30 on the first slide part 29 takes place via these guides by means of pins 31 and guide grooves 32. Displaceable mountings of a different design can of course be realised at this site.

The tilt slide 5 is pivotably secured to the second slide part 30 by means of the pins 42, so that on the one hand it can be pivoted about the pins 42 and on the other hand it is forcibly displaced with the second slide part 30 relative to the first slide part 29 and thereby also relative to the body rail 2. Like the second pins 43 of the tilt slide 5, the pins 42 engage the guideways 18, here in the form of slots, at the first slide part 29. The end regions 17 of the guideways 18 are, as known per se, angular or bent. If the pins 43 of the tilt slide 5 enter the end regions 17 upon a relative displacement of the second slide part 30 relative to the first slide part 29 and thereby to the body rail, this automatically leads to a tilting or pivoting of the tilt slide 5 about the pins 42 or the pivot axis defined by the latter.

The retraction spring 15 impelling the retraction mechanism 4 has the ends 37 and 38. The retraction spring 15 is secured by means of the end 37 at the mounting point 39 and thereby at the second slide part 30. The opposite end 38 of the retraction spring 15 is mounted at the mounting point 41 of the first slide part 29, so that the two slide parts 29 and 30 can be tensioned in relation to one another by means of the retraction spring 15. In addition to the retraction spring 15, the retraction mechanism 4 realised here also has, as known per se, a damper 16. In the shown embodiment, it is a linear damper with which the piston rod 36 and the cylinder 35 are moved relative to one another in a longitudinal direction. Suitable dampers are known in the furniture industry and do not need to be explained further here. In other embodiments, the linear damper 16 shown here could also be replaced by a rotary damper or other dampers.

The piston rod 36 of the damper 16 is secured to the second slide part 30 at the mounting point 40, while the cylinder 35 is fixed in an appropriate receiver 45 of the first slide part 29. As a consequence the damper 16 deploys its damping effect upon a relative motion between the first slide part 29 and second slide part 30.

In addition to the tilt slide 5, the pull-out guide 1 shown here also has the additional tilt slide 19. This is guided and mounted in the additional guide 25 in this embodiment. The additional guide 25 is fixed to the vertically extended wall portion 13 of the central rail 11. The guiding and mounting of the additional tilt slide 19 takes place via an engagement of the pins 34 fixed to the additional tilt slide 19 with the guideways 27, here likewise groove-shaped, having end regions 26 which are angular or arranged in a bent manner. The additional tilt slide 19 is guided in the additional guide 25 in a linearly displaceable manner wall as long as all pins 34 are located outside of the end region 26. If the pins 34 provided for this purpose enter the angular or bent end regions 26, then tilting or pivoting of the additional tilt slide 19 about its pivot axis 24 shown in figs. 11 to 16 takes place. The additional tilt slide 19 has a first claw 20 for releasable engagement with the claw 21 of the tilt slide 5 of the retraction mechanism 4 and a second claw 22 for releasable engagement with the contact element 23 at one of the rails, here the drawer rail 3.

In order that the first claw 20 of the additional tilt slide 19 can engage the claw 21 of the tilt slide 5, an additional slit 12 is provided in the vertically running wall portion 13 of the central rail 11, which slit 12 is in this first embodiment bounded by the longitudinal ends 14 in the form of a slot closed on both sides. The additional slit 12 too is extended longitudinally parallel to the retraction direction 6. The additional tilt slide 19 is mounted therein so as to be displaceable parallel to the retraction direction 6.

Reference is made to figs. 11 to 16 with regard to the manner of operation of the retraction mechanism 4 and its cooperation with the additional tilt slide 19. The different operating states are now explained with reference to these figures. Figs. 11 and 12 show the first operating state in which the claw 21 of the tilt slide 5 engages the first claw 20 of the additional tilt slide 19 and the second claw 22 of the additional tilt slide 19 engages the contact element 23. In Figs 11 and 12, the drawer rail 3 and the central rail 11 are fully retracted in the retraction direction 6 into the body rail 2. If starting from this situation according to Fig. 11 and 12, the furniture part together with the drawer rail 3 and also together with the central rail 11 via the synchronization by means of the synchronization roller 33 is pulled out a bit, then the first operating state is maintained first of all in that the tilt slide 5 is moved along the linear portion of the guideways 18 with the additional tilt slide 19 which is definitely secured to the central rail 11. Upon this motion of the tilt slide 5, the second slide part 30 is also forcibly displaced against the first slide part 29 in a manner parallel to the retraction direction 6, whereby the retraction spring 15 clamped therebetween is tensioned. When the pins 43 enter the angular or bent end regions 17 of the guideways 18 upon this pulling out motion, the tilt slide 5 is hereby on the one hand forcibly pivoted about the first pins 42 and on the other hand via the engagement of the pins 43 with the end regions 17 fixed in this pivoted position. The claw 21 of the tilt slide 5 thereby releases the first claw 20 of the additional tilt slide 19, whereby the first operating state ends.

The second operating state follows, shown in figs. 13 and 14. In this state, the first claw 20 of the additional tilt slide 19 and the claw 21 of the tilt slide 5 of the retraction mechanism 4 are no longer engaged. The second claw 22 of the additional tilt slide 19 is however located still engaged with the contact element 23 and thereby with the drawer rail 3. In this operating state, upon further pulling out of the drawer rail 3 counter to the retraction direction 6 there is also movement of the additional tilt slide 19 first of all along the linear region of the guideways 27 in the additional guide 25. If now the front pins 34 of the additional tilt slide 19 reach the angular or bent end regions 26 of the guideways 27, then the additional tilt slide 19 is also forcibly pivoted about its pivot axis 24. The second claw 22 of the additional tilt slide 19 hereby releases the contact element 23, whereby the third operating state according to figs. 15 and 16 is reached. Through the engagement of the front pins 34 of the additional tilt slide 19, the additional tilt slide 19 remains in the position shown in figs. 15 and 16, while the drawer rail 3 and the central rail 11 are pulled out further counter to the retraction direction 6. The additional tilt slide 19 remains in the third operating state according to figs. 15 and 16 until the contact element 23 strikes the second claw 22 of the additional tilt slide 19 upon pushing of the drawer rail 3 and the central rail 11 into the body rail 2 in the retraction direction 6. Through this collision, the front pins 34 of the additional tilt slide 19 are pulled from the angular or bent end regions 26 of the guideways 17 in that the additional tilt slide 19 is pivoted about the pivot axis 24. There then ensues the situation as shown in figs. 13 and 14. Accordingly further pushing in of the drawer rail 3 and the central rail 11 then subsequently leads to collision of the first claw 20 of the additional tilt slide 19 with the claw 21 of the tilt slide 5 of the retraction mechanism 4. The tilt slide 5 is hereby pivoted back. Its pins 43 are hereby pivoted out of the bent or angular end regions 17 of the guideways 18, whereby the tilt slide 5 is released. In this state, the pretensioned retraction spring 15 pulls the tilt slide 5 together with the second slide part 30 in retraction direction 6 into the initial position shown in figs. 11 and 12. There hereby takes place an automatic retraction of the drawer rail 3 and the central rail 11 into the fully retracted position according to figs. 11 and 12.
