Description

The present invention relates to a sliding member for guiding a sliding or Abstellschiebetür or the like and a guide for sliding or Abstellschiebetüren or the like with such a sliding element.

Such a sliding element is for example from the DE 20 2005 015 034 known. The sliding element is received in an undercut shaped and provided on the frame of the door groove and slidably guided in the longitudinal direction. It has a passage opening which is designed for receiving a journal. The journal is rotatably mounted in the through hole and connected to a stay. This is connected at its end opposite the journal end with a door leaf or the like.

The journal has a groove extending in the circumferential direction and is secured in the passage opening by means of a spiral spring against falling out. The spiral spring is in turn firmly connected to the sliding element. Upon insertion of the journal in the passage opening the bending spring is bent by its located in front of the circumferential groove part and engages in the recess of the circumferential groove, as soon as the bearing pin is in the desired position in the through hole.

When disassembling the spiral spring is bent again with a specially provided for this purpose tool until it releases the journals and this can be removed. Whether the bearing pin is in the desired position in the through hole and is secured by the engaging in its circumferential groove bending spring is not readily apparent to a viewer from the outside.

The EP 1 555 368 B1 discloses a fitting for a tilting and tilting movement of a wing with guide elements, which are arranged displaceably on a guide on the frame. On the guide element, a bearing is formed, on which a pivot pin of a Ausstellarmes can be locked. Such locking takes place via an eccentric, which moves a locking slide.

Based on the above-described prior art, the present invention seeks to provide a sliding element for guiding a sliding or Abstellschiebetüre or the like and such a guide, the bearing pin and thus the entire guide mechanism can be easily and safely mounted, a Possibility for a visual check is given whether the bearing pin is secured in the desired manner and the assembly can be performed easily and quickly without the aid of a tool.

According to the invention, this object is achieved by a sliding element for guiding a sliding or Abstellschiebetür or the like having the features of claim 1. The sliding element comprises at least one sliding body and a securing element, wherein the sliding body has a guide for a bearing journal, the sliding body and the securing element mutually displaceable in a locking position and a release position and the securing element locks the bearing pin in the guide in the locked position and releases it in the release position.

Movable in the sense of the present invention means that the sliding body and the securing element can be positioned relative to one another in a different position, that is to say that they are translationally displaceable relative to one another and / or are rotatable. Preferably, sliding body and securing element can be positioned relative to one another in two different end positions, namely the locking position on the one hand and the release position on the other hand. In the locking position of the bearing pin is locked by means of the securing element in the guide. In the release position, the securing element releases the bearing journal. From the outside it is expedient for a watcher to see clearly whether the securing element is in the locking position or the release position. It is created as a visual control option for the locking state of the journal.

An actuation of the securing element in order to displace this relative to the sliding body, in particular during assembly of the journal in the guide advantageously without the use of tools possible. The disassembly is preferably possible without the use of specially provided for this purpose tools, possibly even without the use of a tool. For this purpose, a handle or the like is formed on the securing element, for example a tab or the like, on which it can be grasped and moved by an operator.

The securing of the journal in the guide is preferably carried out by a positive connection with the fuse element. The bearing pin is usually provided with an undercut behind which the securing element can engage. The undercut may be formed, for example, as a circumferential groove. Other forms are conceivable for this purpose. The fuse element according to one embodiment of the invention has a keyhole-shaped passage opening. In the area of large diameter of the bearing pin is inserted. The through hole and the bearing pin are coordinated so that located in front of the undercut areas of the journal through the area of Through hole with large diameter fit while the portion of the passage opening with a small width is formed so that it can accommodate the undercut, the remaining portions of the journal but not pass through. In the release position, the area of large diameter is preferably congruent over the guide. In the locked position, the area of small width is above the guide.

Preferably, the slider and the securing element are parallel to the guide direction in the guide displaced relative to each other. As a result, a displacement of the securing element relative to the sliding body can be carried out without problems even within the limited space in a guide rail. The securing element can be displaceably guided, inter alia, by latching projections on the sliding body.

In order to avoid unintentional release of the locking of the journal, is further proposed with the invention that the securing element is biased relative to the slider in the locking position. This bias is generated in an advantageous manner by means of a spiral spring. Furthermore, the securing element can be locked relative to the sliding body. For this purpose, the securing element or the sliding body preferably has a resilient locking element, which fixes the securing element relative to the sliding body in the release position. This locking element is biased due to its resilient properties in a first position in which it engages in a structure of the securing element or the slider or cooperates with such. As long as the securing element is not in the release position, the locking element is supported on the slider or the securing element so that, in principle, a relative movability of these to one another is possible. As soon as the securing element reaches the release position, the locking element springs by its bias in the direction of its rest position and locks the securing element in the release position.

The locking element is preferably brought by the introduced in the leadership of the sliding bearing pin from its locking element locking position in a releasing this position. In this, the securing element relative to the slider is displaceable. In a particularly advantageous manner, the unlocking is achieved by the insertion of the journal into the guide during its assembly, without the need for a separate operation and in particular a use of a tool is necessary. The assembly is therefore particularly simple and can be carried out by a person without problems by hand. According to a further embodiment, the sliding body is locked in the locking position relative to the securing element. Preferably, for this purpose, the sliding body or the securing element has a latching nose, which fixes the securing element relative to the sliding body in the locking position. This is achieved for example by the locking lug engages in the locking position in a through hole or the like of the securing element or the slider. As a result, the whereabouts of the securing element is secured in the locked position. Preferably, the locking lug is elastic. In order to enable a change from the locking position to the release position, the locking achieved by the locking lug is possibly releasable using a tool. In particular, the tool can be guided from the outside through the passage opening and used to push the locking lug out of the passage opening under elastic deformation. Due to its elastic properties, the locking lug will engage again in the passage opening at a renewed reaching the locking position.

According to a further proposal of the invention, the sliding body made of plastic or at least partially made of plastic. It is then designed, for example, as an injection-molded component. Preferably, the slider has a U-shaped cross-section with a bottom wall and arranged on this side walls. In one embodiment of the invention, a cover element is arranged on a side wall, which in turn carries the locking element. In addition to this cover element lid elements can be further provided. Locking lug and locking element are arranged on one or more of the cover elements. Particularly simple is the cover element or the cover elements are connected to a living hinge hinged to the side wall. By pivoting about the film hinge of the bottom wall opposite side of the slider is closed. The cover element is fixed in position in this position with a latching connection to the slider. The latching connection is formed for example by provided on the cover element and the side wall locking projections or depressions, which interlock with each other.

Side walls, bottom wall and cover element form a cavity in which the securing element is arranged. The walls and the cover or the elements can serve as guides for the securing element. The securing element is preferably a stamped and optionally bent metal sheet. It is advantageously shaped such that it protrudes in the release position over one end of the slider.

That in the Fig. 1 Slider 50 shown has a slider 1, a fuse element 2 and a coil spring 7. As Fig. 2 can be seen, the slider 50 is slidably received in a guide 60 in the longitudinal direction. The guide 60 is in turn arranged on a frame for a Abstellschiebetür. On a stay 19, a bearing pin 4 is arranged. This is substantially cylindrical and has an undercut 4a with a relation to the other areas of the journal 4 reduced diameter. The extension arm 19 is articulated with its the bearing journal 4 opposite end to the wing of the Abstellschiebetür.

The slider 1 is an elongated plastic injection molded part. It has a bottom wall 12, on whose elongated sides side walls 13,14 are arranged.

The bottom wall 12 is centrally provided with a passage opening whose side walls form a guide 3. On both sides of the guide 3 more substantially rectangular recesses 21 and 22 are provided in the bottom wall 12. At the opposite end of the guide 3 faces of the recesses 21,22 is in each case arranged a spring receptacle 23, for example in the form of a cylindrical pin whose function will be described later. End of the bottom wall 12 is in each case a recess 18,18 '. This has a substantially T-shaped configuration with a widened end portion and an approximately semi-circular recess. The slider 1 is formed symmetrically to a line 24 extending through the middle of the guide 3 transversely to its longitudinal direction. This creates the advantage that when installing the slider in the guide does not have to be paid to its orientation.

At the bottom wall 12 opposite side of the side wall 14, two cover elements 15,15 'in each case by means of a film hinge 16, 16' pivoted. The film hinges 16,16 'are formed by thin wall portions of the plastic material, which are slightly elastically deformable due to its material properties and the thin wall thickness. At the film hinge 16,16 'opposite side, each cover member 15 15' each have a locking elements 17,17 'on. Both cover elements 15, 15 'have a central region 25, 25' of increased wall thickness, which protrudes in the direction of the bottom wall 12 when the cover element 15, 15 'is closed and forms a guide surface for the securing element 2. In the middle region 25, 25 ', in each case one latching lug 9, 9' is formed in a recess. This projects in the closed lid member 15,15 'in the direction of the bottom wall 12 and has resilient properties.

On the cover element 15, a locking element 8 is arranged. This is elongated and resilient due to its shape and material properties. At its end a cam 26 is formed.

On the side wall 13 latching elements 27,27 'are arranged, which cooperate with the lid element closed with the latching elements 17,17' and lock the lid members 15,15 'with the side wall 13. In this state, the bottom wall 12, the side walls 13, 14 and the cover elements 15, 15 'form a cavity in which the securing element 2 is arranged.

The securing element 2 is an elongated metal element produced by stamping and embossing. It has on a short end side of a bent over 90 degrees tab 28. From the fuse element 2 recesses are punched out. These are an end locking recess 10, an end recess 29, a keyhole-shaped through hole 5 with a large diameter passage 5a and a small diameter recess 5b, and a spring recess 30. The spring recess 30 is formed by punching a U-shaped Area and then bending the remaining web 31 formed by 90 degrees. The web 31 is provided with a spring receptacle 32.

The interaction of the individual elements of the slider 50 is best in the FIGS. 3 to 5 recognizable. The Fig. 3 shows the slider 50 and the extension arm 19 of the guide during a first time in the assembly, while the Fig. 4 these during a subsequent time in the assembly and the Fig. 5 this shows during disassembly. The securing element 2 is arranged in the cavity surrounded by the bottom wall 12, the side walls 13, 14 and the cover elements 15, 15 ', wherein the tab 28 and the web 31 are oriented in the direction of the bottom wall. In this position, the securing element is guided, inter alia, by resilient latching projections 11. The arrangement of the securing element 2 on the slider 1 is carried out by the in the FIGS. 3 to 5 the Ausstellarm 19 opposite side of the slider 1 in the direction of the bottom wall 12. In this case, the securing element 2 is guided past the locking projections 11, which dodge due to their resilient properties of the fuse element 2 and spring back after its passing back to its original position, so the train previously mentioned leadership.

In the recess 21, the coil spring 7 is arranged. In this case, the pin 23 and the spring receptacle 32 engage in the end-side openings of the coil spring 7 and center and guide them in the recess 21. Due to the symmetrical shape of the slider 1, the coil spring 7 can be arranged in the same manner in the recess 22. The coil spring 7 is in the in Fig. 3 shown position pressure-loaded and biases the securing element 2 against the slider 1 before. The diameter of the guide 3 and the bearing pin 4 are coordinated so that the bearing pin 4 is guided in the guide. In this case, a displacement of the bearing pin 4 in the direction of its longitudinal axis and a rotation around it is possible. The diameter of the passage 5a is selected so that the bearing pin 4 can be pushed therethrough. The width of the recess 5b is smaller than the diameter of the journal 4, but so selected that the undercut 4a of the journal 4 can be accommodated in this.

In the Fig. 3 is the fuse element 2 in the release position. It protrudes on the side of the tab 28 clearly above the end of the slider 1. The coil spring 7 is compressed and urges the fuse element 2 in the flap 28 opposite direction, ie in the Fig. 3 to the right. The cam 26 of the locking element 8, which is biased in the direction of the bottom wall 12 because of its spring properties, engages in the recess 5b of the passage opening 5 on. As a result, a displacement of the securing element 2 in the flap 28 opposite direction is prevented. The locking lug 9 is supported on the securing element 2 in the region between the locking recess 10 and the spring recess 30. In the release position, the passage 5a with a large diameter of the passage opening 5 is congruent with the guide 3.

To that in the Fig. 3 shown time, the bearing pin 4 - as indicated by the arrow - inserted into the guide 3. Since the guide 3 and the passage 5a are here congruent to each other, a pushing through of the bearing pin 4 through the guide 3 and the passage opening 5 is possible. By the advance of the bearing pin 4 in the direction of the arrow this abuts the spring arm of the locking element 8. By a further feed thereby the locking element 8 is displaced in the direction of the feed, whereby the cam 26 moves out of the recess 5b of the through hole 5 and the securing element 2 releases. At the time of release of the bearing pin 4 is inserted so far into the guide that the undercut 4a is in the plane of the fuse element 2.

Due to the bias of the coil spring 7, the fuse element 2 moves now in the in the Fig. 3 right direction. In this case, the indentation 5b slides into the undercut 4a of the journal 4. The movement of the securing element 2 ends when this in the in Fig. 4 is shown locked position. In this, the tab 28 no longer protrudes beyond the end of the sliding body 1, but is received in the widened end portion of the recess 18. The tab 28 is now no longer visible to a viewer from the outside, whereby the achievement of the locking position is displayed. In the locking position of the bearing pin 4 is locked by the engagement of the recess 5 b in the undercut 4 a in the guide 3.

An inadvertent release of the securing element 2 from the locking position is prevented in that - as in the Fig. 4 can be seen - the latch 9 engages in the locking recess 10. The cam 26 is supported between the passage opening 5 and the spring recess 30 on the securing element 2.

For the purpose of disassembly, the securing element 2 must first be brought from the locking position to the release position. How this is accomplished is in the Fig. 5 shown. The detent 9 is pushed out by the use of any tool from the locking recess 10.

As a tool is in the Fig. 5 an Allen wrench shown, but it is any pen-like object that fits through the semicircular recess of the recess 18 therethrough, such as a screwdriver or the like. When the locking recess 10 is released from the locking lug 9, the tool in the direction of the tab 28 - that is shifted to the left in the figure - whereby the securing element 2 is brought against the tension of the coil spring 7 from the locking position to the release position.
