Description

The invention relates to a side guide for an extendable from a furniture body high cabinet part, with a first, to be connected to the ceiling inside of the furniture body rail having at least one rotatably mounted about a vertical axis guide roller, and with a second, to be determined on the extendable cupboard part rail, wherein the at least one guide roller rotatably mounted about the vertical axis engages in a space between the vertical webs of the second rail and on one of the vertical webs a stop unit for limiting the extension of the second rail from the first rail is mounted, which comprises a stop member arranged in the space between the vertical legs, a holding arm for connecting the stop unit with the vertical web and a connecting part connecting the stop member with the holding arm comprises, which passes through an extending in the longitudinal direction of the second rail slot recess in the vertical web.

Side guides for pull-out high-ceiling parts are used to keep the pull-out tall unit in an upright position. These side guides may consist of two or more rails, in the latter case, the side guide may be formed telescopically or differentially.

To accommodate the weight of the pull-out cupboard part is a specified at the bottom of the furniture body pull-out. Although such a pull-out guide is equipped with stops that limit the extension, it is expedient to provide a stop device also in the top side guide arranged, which limits the extension.

A side guide of the type mentioned is from the AT 3 164 U known. In one embodiment, the support arm is slidably connected to the vertical web of the second rail in this side guide. In the fully rearward shifted position, the stop member engages over the rear edge of a Langlochausnehmung hook-like. When the holding arm is pushed forward relative to the second rail, the abutment part can be swung out of the intermediate space between the vertical webs by the slot recess, whereby the guide rollers can be moved into the intermediate space between the vertical webs of the second rail during assembly and disassembly of the extendable high-cabinet part . Are moved out of the gap. In another embodiment the holding arm fixedly attached to the vertical web of the second rail and the stop member can be swung out under elastic curvature of the support arm through an opening of the vertical web from the intermediate space to retract the guide rollers during assembly or extend during disassembly.

A problem with conventional extension restrictions for the side guide of a pull-out cupboard part is that the pull-out rail of the pull-out guide, on which the pull-out cupboard part is mounted, in the extended state of the pull-out cupboard part depending on the weight and loading of the pull-out cupboard part at its front end more or less lowers a lot. This results in a more or less strong tilting of the extendable cupboard part to a horizontal, perpendicular to the withdrawal direction axis. This can have the consequence that at a high weight on the lower pull-out weight, the pull-out limiter for the side guide already takes effect when the end stops for the lower pull-out guide are not yet reached. This results in a high load on the upper side guide, which can even lead to a bend of the rearmost, cooperating with the stop member guide roller of the first rail. But if the extension limit for the upper side guide is adjusted so that even with a high weight on the lower pull-out weight, the pull-out limit for the side guide does not take effect before the pull-out limit for the lower pull-out guide, this will result in a low load on the lower pull-out guide Weight to an unfavorable effect. In this case, that is, the lower pull-out guide runs against its end stops when the upper side guide has not yet reached its pull-out limit. In a somewhat sweeping undressing of the pull-out furniture part, it then comes to a perceived by users as disturbing whip-like pre-swing of the upper end of the pull-out cupboard part when the pull-out of the lower pull-out guide is effective.

The object of the invention is to provide an improved side guide of the type mentioned, in which the problem described can be at least reduced. According to the invention, this is achieved by a side guide of the type mentioned.

The inventive design, the extension limit of the side guide to the intended weight and the intended payload of the extendable cupboard part is adjustable. Even with the assembly of the side guide, greater tolerances can be allowed for the attachment of the first rail on the ceiling inside of the furniture body in view of the adjustment of the stop unit, which facilitates the assembly.

In an advantageous embodiment of the invention, the holding arm of the stop unit and the vertical web of the second rail can be positively connected via intermeshable toothings. It can be provided by a fine adjustment for the position of the stop member.

Preferably, to release the connection of the holding arm with the vertical web of the second rail, the at least one connecting element of the holding arm can be lifted in the direction transverse to the longitudinal direction of the second rail from the at least one connecting element of the vertical web of the second rail.

An advantageous embodiment of the invention provides that at a force lying above a predetermined limit, which acts in the longitudinal direction of the second rail on the connecting elements of the stop unit and the second rail, these connecting elements are overcoming the positive connection in the longitudinal direction of the second rail against each other , It can thereby be reliably prevented in an incorrect setting of the extension limit of the upper side guide damage to the cooperating with the stop member guide roller.

If in the context of this document "front" and "rear" is mentioned, this is related to the pull-out direction of the pull-out cupboard part from the furniture body, i. a further forward part of the side guide is closer to the pull-out end of the side guide as a further back lying part.

In the embodiment shown in the figures, the extendable cupboard part 1 is designed in the form of a Ausziehrahmens. A front mounted on Ausziehrahmen aperture is omitted in Fig. 1 for the sake of simplicity as well as on Ausziehrahmen to be mounted shelves or compartments. From the furniture body 2 parts of the bottom 5 and the ceiling are shown only with dashed lines. At the bottom 5 a pull-out guide 3 is fixed, which carries the pull-out cupboard part 1 and relative to the furniture body 2 between its inserted and displaceable in its extended position. Such extension guides 3 are known in different embodiments.

To guide the upper end of the extendable cupboard part 1 against tilting at right angles to the withdrawal direction 7 is a side guide 4. This includes a first rail 8, which is connected in the illustrated embodiment via a carcass rail 9 of the side guide 4 with the inside of the ceiling 6 of the furniture body 2 , wherein the carcass rail 9 is fixed to the ceiling 6 and the first rail 8 relative to the carcass rail 9 between a retracted end position and an extended end position is displaceable. For displaceably guiding the first rail 8 relative to the carcass rail 9 along the pull-out direction 7, rolling elements rotatably mounted, for example, arranged between the rails 8, 9 can be provided in a cage. The displacement of the first rail 8 relative to the carcass rail 9 in the pull-7 is limited by stops.

The first rail 8 has a plurality of longitudinally spaced apart from the first rail 8 about vertical axes 10 rotatably mounted guide rollers 11. Here, 8 axle journals 13 are attached to a web 12 of the first rail, which project from the web 12 down and at its free ends, the guide rollers 11 rotatably support.

The side guide 4 further includes a second rail 14. This has spaced-apart vertical webs 15, 16, between which there is a gap 17, in which the guide rollers 11 engage in the assembled state of the side guide 4.

The vertical webs 15, 16 are from a connecting web 18 upwards, wherein the second rail 14 is formed in the embodiment shown a total of U-shaped.

In the embodiment shown in the figures, the second rail 14 connects vertical frame legs 19, 20 of the extendable cupboard part 1 at their upper ends together. At their lower ends, the vertical frame legs 19, 20 are interconnected by a horizontal frame leg 21. The second rail 14 thus represents an integral part of the Ausziehrahmens the pull-out cupboard part 1.

The previously described parts of the side guide are known and customary.

On one of the vertical webs 15, 16 of the second rail 14, a stop unit 22 is mounted, which limits the extension of the second rail 14 from the first rail 8. The stop unit 22 comprises a cooperating with the rearmost guide roller 11 of the first rail 8 stop member 23 which is arranged in the intermediate space 17 between the vertical webs. The stop member 23 is connected via an intermediate piece 24 with an elongated, in the longitudinal direction of the second rail 14 extending support arm 25 which is located on the outside of the vertical web 15 on which the stop unit 22 is mounted. The intermediate piece 24 passes through a slot recess 26 of the vertical web 15, which extends in the longitudinal direction of the second rail 14. The intermediate piece 24 is here in the slot recess 26 slidably mounted, ie its measured width in the vertical direction is slightly smaller than the width B measured in this direction Langlochausnehmung 26. The measured in the vertical direction width b of the stop member 23, however, is greater than the width B of the slot recess 26 refer to this latitude to an adjusting portion 27 of the slot recess 26th

In order to fix the stop unit 22 in different displacement positions relative to the second rail 14 on the second rail 14, the holding arm 25 has a connecting element 28, which is fixed in relation to the second rail 14 state of the stop unit 22 with a connecting element 29 of the vertical web 15 of the second Rail 14 interacts. The connecting element 28 of the support arm 25 is formed in the embodiment shown by a piece piece-like elevation 30 of the support arm 25 on the vertical web 15 facing side of the support arm 25. The upper and lower edges of the elevation 30, which extend in the longitudinal direction of the second rail 14, are provided with teeth 31. The connecting element 29 of the vertical web 15 is formed by a longitudinal recess of the second rail 14 extending slot opening 32, the upper and lower extending in the longitudinal direction of the second rail 14 edges are provided with teeth 33. The measured in the longitudinal direction of the second rail 14 length of the elevation 30 is shorter than the length of the slot recess 32, wherein the teeth 31, 33 in different displacement positions of the support arm 25 to the second rail 14 are engageable with each other by the survey 30 in the Langlochausnehmung 32 is introduced. In the interlocking state of the connecting elements 28, 29, these are thus in a relation to the longitudinal direction of the second rail 14 positive engagement.

The slot recess 26 has in the region of one of its ends, for example in the region of its rear end, a widening 34 whose measured width in the vertical direction is greater than the width B of the stop member 23. This widening 34 is located outside of the adjustment section 27 of the oblong hole 26th

Preferably, the stop member 23 is located in the region of one longitudinal end of the support arm 25 and the connecting element 28 of the support arm 25 is arranged in the region of the other longitudinal end of the support arm 25.

In the illustrated embodiment, a holding part 35 is further attached to the support arm 25 in the area between the connecting element 28 and the stop member 23 on the side facing the vertical web 15, which includes a neck portion 36 and a contrast broadened head portion 37, the remote from the support arm 25 end the neck portion 36 is arranged. The neck portion 36 passes through a slot 38 in the vertical web 15 of the second rail 14, which extends in the longitudinal direction of the second rail 14. The measured width in the vertical direction of the head portion 37 is, at least over an adjustment of this slot, greater than the width of the slot 38. At one end, for example at the front end of the slot 38 has a widening 39, the measured width in the vertical direction greater as the width of the head section measured in this direction 37 is. This widening 39 is located outside the adjustment section 40 of the slot 38.

On the side facing away from the vertical web 15 side of the support arm 25 is a handle 41 from.

The stop unit 22 is preferably formed in one piece, in particular in the form of an injection molded part.

The stop unit 22 limits the displacement of the second rail 14 relative to the first rail 8 in the pull-7, by the rearmost guide roller 11 starts at the located in the space 17 stop member 23.

If the position of the abutment member 23 is to be adjusted relative to the second rail 14 in the longitudinal direction of the second rail 14, the connecting elements 28, 29 of the support arm 25 and the vertical web 15 are disengaged. The holding arm 25 is pulled away in the region of the connecting element 28 from the vertical web 15, wherein it bends accordingly. For this purpose, the holding arm 25 consists of a sufficiently elastic material, preferably of a plastic material. When the connecting elements 28, 29 are disengaged, the intermediate piece 24 can be displaced in the adjustment section 27 of the slot recess 26 to a desired position and the connecting elements 28, 29 can be in or near this desired position of the intermediate part 24 and the stop member 23rd be engaged again.

In this way, the stop member 23 can be adjusted over an adjustment. The farthest back and furthest forward settings of the stop member 23 are shown in Figs. 2 and 3.

During the displacement of the intermediate piece 24 in the adjustment section 27, the neck portion 36 of the preferably present holding part 35 shifts in the adjustment section 40 of the slot 38. Thus, an additional guide for the stop unit 22 is formed by the holding part 35 cooperating with the slot 38. Furthermore, an additional security against unintentional pulling out of the connecting element 28 from the connecting element 29 is thereby provided.

For mounting the stop unit 22 on the second rail 14, the stop member 23 is first introduced by the broadening 34 of the elongated recess 26. As a result, the intermediate piece 24 is displaced to the other end portion of the slot recess 26. In this position, the head portion 37 of the holding part 35 can be inserted through the widening 39, whereupon the neck portion 36 and the intermediate piece 24 are displaced into the adjusting portions 40, 27 and the connecting members 28, 29 are connected together in a suitable position of the stop unit 22. Also, the reverse assembly process, ie first the insertion of the holding part 35 by the widening 39 and after appropriate displacement of the stopper unit 22, the insertion of the stop member 23 by the broadening 34 is possible. In a modified embodiment, it would also be conceivable and possible for the spacers 34 and 39 to be arranged such that the holding part 35 and the stop part 23 can be introduced simultaneously through the corresponding spacers 39, 34 in a specific position of the stop unit 22.

If, in already mounted stop unit 22, the guide rollers 11 of the first rail 8 to be retracted or extended out of the intermediate space 17 between the vertical webs 15, 16, the holding member 35 may remain in engagement with the vertical web 15 and only the stop member 23 through the Broadening 34 of the slot recess 26 are pulled out, wherein the stop unit 22 has been moved at the open connection of the connecting elements 28, 29 to the appropriate location (see Fig .. 4).

In an advantageous embodiment of the invention can be provided that the positive connection between the connecting elements 28, 29 at a predetermined limit exceeding force, which is directed toward the rear end of the second rail 14 and acts on the stop unit 22, "slip" can. This is achieved by a corresponding adaptation of the shapes of the teeth 31, 33, the mutual depths of engagement and the elasticity of the material of the connecting element 28 of the support arm 25. In the illustrated embodiment, the teeth 31, 33 are formed like a sawtooth, wherein in a direction towards the rear end of the second rail 14 acting force the inclined flanks of the teeth are pressed against each other.

When "slipping" of the connecting element 28 relative to the connecting element 29, there is no destruction of these connecting elements 28, 29. In this way, an "overload protection" is provided, which is effective when the extension limit for the side guide 4 before the extension limit of the pull-out 3 to Wearing comes, this statement limit for the side guide 4 is thus not set correctly. The maximum force acting on the rear guide roller 11 cooperating with the stop member 23 is thereby limited.

It is preferably provided that there is a slippage of the positive connection between the stop unit 22 and the second rail 14, if at a total weight of the extendable furniture part (including load) of 120 kg, the starting speed of the second rail 14 to the stop member 23 a value of 0.6 m / sec.

Various modifications of the embodiment shown are conceivable and possible without departing from the scope of the invention. For example, the connecting elements 28, 29 could be formed in another way. In principle, it would also be conceivable and possible to provide on the holding arm 24 a pin projecting in the direction of the vertical web 15, which pin can be inserted into one of a plurality of separate bores in the vertical web 15.
