Description

The invention relates to a guiding device with an elongated first guiding element and with an elongated second guiding element arranged in extension thereof to form a guideway, along which a moving element can be moved in a guided manner.

From the WO 2015/132245 A1 a guide device for a sliding door fitting is known, which comprises a rail-shaped first guide element and a rail-shaped second guide element. In the case of relatively long sliding door fittings, it is desirable for logistical reasons (packaging expenditure) to assemble a guide for a sliding door from a plurality of guide elements, preferably of the same length. The generally non-flush butt joint between the first guide element and the second guide element creates a jump edge that can be perceived by a user when the sliding door is moved. In order to avoid such a jump edge, the WO publication provides an elongated insert part that fits into a recess in the first and second Guide element is used. The insert is made of a flexible material so that it does not go beyond the length of the individual guide elements during packaging. A disadvantage of the known guide device, however, is that the material required for the bridging means formed by the insert part is relatively large, since the insert part has to be inserted into the recess over the entire length of the guide elements, so that an undesirable jump edge is avoided. The insert part thus lifts the guideway, since a displacement element, for example designed as a roller, no longer rests on a surface of the guide elements, but on the insert part.

The object of the present invention is to develop a guide device such that the transport of the guide device is simplified due to the division into several guide elements and a homogeneous bridging of a raceway in a transition area between two adjacent guide elements is ensured in a material-saving manner.

To achieve this object, the invention in connection with the preamble of claim 1 is characterized in that a bridging means is provided in a mutually facing end region of the first guide element and / or the second guide element, by means of which the displacement element in the transition region between the first guide element and the second guide element can be moved guided only along a continuous additional path.

The particular advantage of the invention is that a homogeneous bridging between two adjacent guide elements is ensured in a material-saving manner, so that a moving element along the guide elements can be moved homogeneously or without jumps from the first guide element to the second guide element and vice versa. Basic idea of The invention is to design bridging means in such a way that the moving element is guided in the transition region over an additional track and not over the actual guideway, the additional track having no undesired edges. The contact between the moving element and the guideway is thus interrupted in the transition region between the first guiding element and the second guiding element and replaced by the additional path. In order to avoid a jump of the travel element during the transition from the guideway to the additional path or vice versa, the additional path runs at a relatively small acute angle to a plane running parallel to the guideway.

According to a preferred embodiment of the invention, the additional track is formed by an additional guide element which can be fastened to the first guide element and the second guide element and has an ascending section and a descending section with respect to a plane running to the guide track or parallel to the guide track. The rising section is fastened, for example, to the first guide element and the descending section, for example, to the second guide element. For example, a bridge-like additional track can be formed, which in the transition area lifts the moving element with respect to a main running surface of the first and second guide elements forming the guiding track, so that the moving element has no contact with the main running surface. The slope of the ascending or descending section and / or a length thereof is selected such that the distance between the moving element and the main running surface is greater at the abutting edge of the first and second guide elements than an edge that usually arises when the front and second guide elements are connected at the end. Alternatively, the additional track can also run vertically below a plane running to the guide track, so that the additional track does not rise in the direction of the end face of the first and second guide elements, but rather decreases. Such an embodiment is provided if the guide elements have no main running surface in the transition area.

According to a development of the invention, the traversing element is designed as a roller that has a main roller element for coupling to the guideway and an auxiliary roller element for coupling to the additional track. The auxiliary running element thus forms part of the bridging means. The auxiliary barrel element interacts with the additional guide element. The auxiliary running element can advantageously be connected to the main running element in a space-saving manner, preferably in one piece. The auxiliary running element is preferably molded onto the main running element on a side facing a vertical wall of the guide element, so that no additional bulky space is required for the bridging means.

According to a preferred embodiment of the invention, the auxiliary running element is arranged coaxially with the main running element, a radius of the auxiliary running element being larger or smaller than a radius of the main running element. The additional guide element is thus recessed or raised with respect to a main running surface of the first and second guide elements or the guideway thereof. The additional guide element and the auxiliary running element are thus arranged between the main running surface of the first and second guide elements on the one hand and a vertical wall thereof on the other.

According to a development of the invention, the additional guide element is arranged partly in a recess of the first guide element and partly in a recess of the second guide element. The rail-shaped additional guide element can for example be mounted in a form-fitting manner in the recesses. The guide elements advantageously do not require any additional fastening means. Already because of the preferably profiled Shape of the guide elements ensures a secure and firm connection of the additional guide element to the respective guide elements.

According to a further development of the invention, the additional guide element has a grip section, so that the additional guide element can be brought into the mounting position in a simple manner or can be moved into a disengaged position by separating the two guide elements from the mounting position.

According to a further development of the invention, a base section of the additional guide element is designed to follow an end face of the first guide element and / or the second guide element. The base section thus forms a connection between the end faces of the guide elements facing each other.

According to a development of the invention, not only does the feed element protrude from the base section, but also a support element, which is designed to follow a contour of a side web of the first or second guide element. This can advantageously ensure a secure and positive connection between the bridging body on the one hand and the first guide element and second guide element on the other hand.

According to a development of the invention, an angle of inclination of the ascending or descending section of the additional guide element is in the range from 0.5 ° to 5 °. The pitch angle is advantageously so small that there is no perceptible jump in the travel element during the transition from the guideway to the additional path and vice versa.

Further advantages of the invention result from the further subclaims.

An embodiment of the invention is explained below with reference to the drawings.

A guide device according to the invention is preferably used for sliding doors. Alternatively, it can be used for other applications where rail-shaped parts are to be connected to one another at the end and a "seamless" transition of these parts is to be ensured.

How out Figure 1 it can be seen, the guide device can be provided for the linear displacement of sliding doors 40 with respect to a fixed body 41 of a sliding door cabinet 42 (furniture).

The guiding device comprises at least one elongated first guiding element 1 and one elongated second guiding element 2, each of which is preferably profiled and each has a guideway 3, along which a travel element 4 can be guided in the direction of extension E of the two guiding elements 1, 2. In the present exemplary embodiment, the traversing element 4 is designed as a roller that is guided so that it can roll on a running surface. According to an alternative embodiment of the invention, not shown, the travel element 4 can also be designed as a sliding or sliding element, which is guided displaceably along rail-shaped sections of the guide elements.

In the present exemplary embodiment, the first guide element 1 and the second guide element 2 are fastened to the body 41 of the sliding door cabinet 42 in the assembled state. The moving element 4 is coupled, for example, to the sliding door 40, which can thus be brought into a closed or open position of the cabinet 42 along the guide elements 1, 2.

To ensure a homogeneous and smooth transition of the roller 4 during the transition from the first guide element 1 to the second guide element 2 or vice versa, a bridging body 5 is provided as a bridging means, which is mounted in a transition area 6 between the first guide element 1 and the second guide element 2.

The bridging body 5 has a base section 7, which is arranged contiguously to an end face 8 of the first guide element 1 and an end face 10 of the second guide element 2. The base section 7 is strip-shaped and has a width b ₁ by which the guide device is extended in the assembled state. Edges 9 of the base section 7 rest in the assembled state on the end face 8 of the first guide element 1 and on the end face 8 of the first guide element 1 facing the end face 10 of the second guide element 2. A base surface 11, which has the width b ₁ , extends between the edges 9 of the base section 7.

On one side of the base section 7, a grip element 12 projects for the manual actuation of the bridging body 5. On a side of the base section 7 opposite the grip element 12, on the one hand a feed element 13 and on the other hand a support element 14 protrude. The feed element 13 has a substantially greater length l _z than a length l _{A of} the support element 14. The support element 14 follows the contour of a side web 15 of the first guide element 1 and the second guide element 2 formed so that it bears essentially below the side web 15. The feed element 13 is arranged above the side web 15, wherein it extends in a recess 16 which is arranged between a main running surface 17 of the guide elements 1, 2 and a vertical wall 18 of the first guide element 1 and the second guide element 2. The main running surface 17 forms a guideway 3, along which a main running roller 20 of the running roller 4 can be moved in a guided manner outside the transition region 6 as the main running element. On the main roller 20, an auxiliary roller 21 adjoins on a side facing the vertical wall 18, which auxiliary roller is movable in the transition region 6 along an additional track 22 provided by the feed element 13. The main roller 20 and the auxiliary roller 21 are integrally connected to one another. Outside the transition region 6, the main roller 20 is in contact with the inner running surface 20 '(concave-shaped peripheral surface 20') or a part of this inner running surface 20 'with the main running surface 17.

In the present exemplary embodiment, two feed elements 13 and two support elements 14 project from the base section 7 at a distance from one another, since the first guide element 1 and the second guide element 2 each have two vertical profiled guide rails arranged at a distance from one another with corresponding recesses 16 for receiving one each Have roller 4.

How out Figure 6 it can be seen, the auxiliary roller 21 is in contact with an additional tread 23 provided by the feed element 13, while the main roller 20 is arranged at a distance a from the main tread 17. The main track roller 20 is thus "raised" in the transition region 6 by means of the additional track 22 caused by the additional guide element 13, so that the main track roller 20 has neither contact with the main track surface 17 of the the first guide element 1 and the second guide element 2 to the side web 15 of the bridging body 5. A power surge caused by a jump edge between the edge 9 of the side web 15 and the end face 8 of the first guide element 1 or the end face 10 of the second guide element 2 would not be introduced into the roller 4, since the main roller 20 is arranged at a distance from the main tread 17 . The additional running surface 23 bridges the abutting edges 9, 11 at the transition from the first guide element 1 to the bridging body 5 on the one hand and at the transition from the second guide element 2 to the bridging body 5 on the other hand. A length l _{z of} the feed element 13 is substantially greater than a length l _{A of} the side web 15 or the width b _{1 of} the base section 7.

zu einer parallel zur Hauptlauffläche 17 angeordneten Ebene B.The additional guide element 13 is designed in the form of a strip and has two arms 24, 25, which each engage in a recess 16 in the first guide element 1 and the second guide element 2. One arm of the additional guide element 13 is designed as an ascending section 24 and the other arm as a descending section 25, as seen from the boundaries of the transition region 6, at which the auxiliary roller 21 comes into contact with the additional tread 23 or the main roller 20 loses contact with the main tread 17. The ascending section 24 and the descending section 25 of the additional guide element run at an incline

to a plane B arranged parallel to the main running surface 17.

des ansteigenden Abschnitts 24 und des absteigenden Abschnitts 25 in einem kleinen spitzen Winkelbereich, beispielsweise in einem Bereich von 0,5° und 5°. Auf diese Weise schmiegt sich der aufsteigende Abschnitt 24 und der absteigende Abschnitt 25 an seinen freien Enden kontinuierlich an die Ebene B an. Im Bereich von freien Enden 27, 28 des aufsteigenden Abschnitts 24 und des absteigenden Abschnitts 25 erfolgt der Wechsel des Kontakts der Laufrolle 4 von der Führungsbahn 3 auf die Zusatzbahn 22 oder umgekehrt. Die freien Enden 27, 28 der Abschnitte 24, 25 laufen unter einem solchen kleinen Winkel

in die Ebene B zu, dass bei Kontaktierung der Zusatzlaufrolle 23 auf den Abschnitt 24, 25 kein Kraftstoß von der Führungsvorrichtung aufgenommen werden muss. Auch während des Laufens auf den Abschnitten 24, 25 entsteht kein Kraftstoß, da der ansteigende Abschnitt 24 und der absteigende Abschnitt 25 über eine kuppelförmige bzw. bogenförmige Spitze 26 miteinander verbunden sind. Der ansteigende Abschnitt 24 geht somit stetig und/oder differenziell stetig in den absteigenden Abschnitt 25 über. Durch die bogenförmige Formung der Spitze 26 entsteht keine Knickstelle an der Zusatzlaufbahn. Eine mathematische Ableitung der Form der Zusatzlaufbahn 22 ist somit stetig.The ascending section 24 and the descending section 25 converge in a tip 26 which is arranged in the region of the base section 7. How out Figure 7 there is an incline angle

the ascending section 24 and the descending section 25 in a small acute angular range, for example in a range of 0.5 ° and 5 °. To this In this way, the ascending section 24 and the descending section 25 continuously nestle against the plane B at their free ends. In the area of free ends 27, 28 of the ascending section 24 and the descending section 25, the contact of the roller 4 changes from the guide track 3 to the additional track 22 or vice versa. The free ends 27, 28 of the sections 24, 25 run at such a small angle

in the plane B that when the additional roller 23 contacts the sections 24, 25, no force shock has to be absorbed by the guide device. Even when walking on the sections 24, 25 there is no power surge, since the rising section 24 and the descending section 25 are connected to one another via a dome-shaped or arched tip 26. The rising section 24 thus merges continuously and / or differentially continuously into the descending section 25. Due to the arcuate shape of the tip 26, there is no kink on the additional raceway. A mathematical derivation of the shape of the additional career 22 is therefore continuous.

The length of the feed element 13 defines the transition region 6, in which only the auxiliary roller 21 is in contact with the additional running surface 23 provided by the feed element 13, while the main roller 20 is not in contact with the guide track 3 provided by the guide rail. Outside the transition region 6, the main roller 20 is in contact with the guide track 3, while the auxiliary roller 21 is at a distance from the guide rail due to the absence of the feed element 13.

In the present exemplary embodiment, the auxiliary roller 21 is arranged coaxially with the main roller 20 and has a radius r ₂ which is greater than a radius r _{1 of} the main roller 20. The main roller 20 and the auxiliary roller 21 each have concave-shaped peripheral surfaces which are in line with the main roller surface 17 or additional running surface 23 are in contact. After a not shown In an alternative embodiment, the radius r _{2 of} the auxiliary roller 21 can also be smaller than the radius r _{1 of} the main tread 20.

Since the auxiliary roller 21 is arranged on a side of the roller 4 facing the vertical wall 18, the guide device does not require any additional space.

How out Figure 6 As can be seen, the auxiliary roller 21 has contact with the additional running surface 23 at two contact points 35 spaced apart from one another in the axial direction. This results from the fact that the additional running surface 23, which is convex in cross section, has a different radius of curvature than the surface of the auxiliary running roller 21, which is concave in cross section In the present exemplary embodiment, the radius of curvature of the additional contact surface 23 is greater than the radius of curvature of the concave surface of the auxiliary roller 21.

According to an alternative embodiment (not shown), the radius of curvature of the additional running surface 23 can also be made smaller than the radius of curvature of the concave surface of the auxiliary running roller 21. In this case, the contact points 35 would be at a smaller distance from one another with respect to a central plane M of the auxiliary running roller 21 extending transversely to the axis run as in the in Figure 6 solution presented.

According to a further embodiment of the invention (not shown), the auxiliary roller 21 can also be cut off along the central plane M or a plane parallel to this, so that there is contact between such an auxiliary roller element and the additional running surface 23 only at a single point of contact 35.

According to a further embodiment of the invention Figure 9 the difference between the guide device and the guide device shown in FIGS. 1 to 6 is that the roller 4 differs. The roller 4 consists only of a single roller with the concave inner peripheral surface 20 'and the opposite flanks 30. The flank 30 thus has the radius r ₂ , while a groove-like depression 31 of the peripheral surface 20' has the radius r ₁ . The flank 30 of the roller 4 forms an end of the roller 4 in the axial direction. The flank 30 of the roller 4 facing the vertical wall 18 lies on the additional running surface 23 of the additional guide element 13. The flank 30 is, for example, guided in a groove 32 of the feed element 13. Thus, only a single point of contact 35 is formed. The additional tread 23 is linear in this case. According to this embodiment, the main running surface 17 runs in a region between flanks 30 delimiting the roller 4, while the additional running surface 23 runs in the region of one flank 30.

According to an alternative embodiment, not shown, the additional running surface 23 can also be arranged on a side of the roller 4 facing away from the vertical wall 18. In this case, the feed element 13 would also have to be arranged on the side of the main running surface 17 facing away from the vertical wall 18.

According to the embodiment according to Figure 9 The auxiliary running element 21 can thus be designed as a ring, for example as a ring surface or as a ring edge, which is in contact with the linear additional track 22. The additional track 22 adjoins the main running surface 17 in the axial direction. It is essential that in cooperation with the feed element 13 the roller 4 is raised with respect to its main running surface 17 in the transition region 6 or is arranged at a distance from it.

According to an alternative embodiment of the invention, not shown, the additional running surface 23 can also be arranged at a distance from the running roller 4 in the axial direction. The axial offset of the feed element 13 or the auxiliary running element 21 depends, for example, on the predetermined profile of the guide rail.

In the case of point contact (a single point of contact 35) with the auxiliary running element 21, the additional track 22 can also be designed as an additional running line.

According to an alternative embodiment of the invention, not shown, the radius of curvature of the additional running surface 23 can be identical to the radius of curvature of the concave surface of the auxiliary roller 21. In this case, a contact between the auxiliary roller 21 and that of the additional tread 23 is flat.

The bridging body 5 is positively connected to the first guide element 1 and the second guide element 2, the side web 15 of the guide elements 1, 2 being encompassed by the feed elements 13 and the support element 14.

The additional track 22 provided by the feed element 13 is arranged vertically and horizontally offset from the guide track 3.

The bridging body 5 is formed in one piece and consists of an injection molded plastic component.

According to an alternative embodiment, not shown, according to Figure 7 A rising section 24 'and a descending section 25' can be one Additional guide element 13 'converge below the plane B into a depression 29 instead of the converging section 24 and the descending section 25 converging to the tip 26 above the reference plane B, as in the above exemplary embodiment. Instead of raising the career in the transition area 6, the career can thus be lowered. This presupposes that there is no guide track 3 in the transition area, for example in cases where the guide rails are cut off in the end area.

The ascending section 24, 24 'and the descending section 25, 25' are preferably straight or slightly curved.

According to an alternative embodiment of the invention, which is not shown, the bridging body 5 can also be connected to the guide element 1 and the second guide element 2 in a force-locking or material-locking manner.

According to a further alternative embodiment of the invention, the bridging body 5 can only be formed by the rectilinear feed element 13, 13 ', which is connected to the first guide element 1 and the second guide element 2 in a form-fitting and / or non-positive or material manner, for example. For example, the feed element 13 can be locked in place by clipping in the groove 32 of the profiled guide rail of the first guide element 1 and the second guide element 2. In this embodiment, the mutually facing end faces of the first guide element 1 and the second guide element 2 directly abut one another.

According to a further alternative embodiment, the bridging body 5 can only be provided by the feed element 13, 13 'and the support element 14 may be formed, which are integrally connected. A base section 7 and a grip element 12 are not provided here. The attachment to the first guide element 1 and the second guide element 2 takes place essentially by means of a positive and / or non-positive connection.

The main running surface 17 of the first guide element 1 or of the second guide element 2 is contacted essentially with the inner peripheral surface 20 'of the main running roller 20 or the running roller 4. The flank 30 is connected to this inner peripheral surface 20' on both sides in the axial direction at.

The same reference numerals of the exemplary embodiments denote the same components or component functions.
