Description

Guide device and guide system

The present invention relates to a guide device which, for example, is used in a guide system as part of an armrest device. In particular, the guide device can be used in a vehicle, for example in a motor vehicle as part of a center armrest. Furthermore, use can be advantageous wherever a defined displacement force is desired and / or required.

Guide devices are known, for example, as drawer guides in order to be able to pull out a pull-out easily and comfortably from a body and to insert it into the same. In stationary applications, especially furniture, a particularly smooth design of the guide device is preferable. In dynamic applications, in particular when used in vehicles, however, an overly smooth guidance device can, for example, cause an armrest of a center armrest to change its position in an undesired manner during braking or acceleration processes.

The present invention is therefore based on the object to provide a guide device which is simple in construction and enables a stable and haptically appealing shifting function.

This object is achieved by a guide device according to claim 1.

The guide device is particularly suitable for use in a guide system.

Such a guide system comprises in particular one, two or more than two guide devices, in particular guide devices according to the invention, for the movable connection of two components.

In particular, a movable armrest position of a center armrest can be realized by means of a guide system.

Embodiment of a coupling device, in which sections of a counterpart of the coupling device are arranged in different positions parallel to a pressing direction.

Identical or functionally equivalent elements are provided with the same reference symbols in all figures. A device shown in FIG. 1, designated as a whole by 100, is, for example, part of an armrest device 102 on which a person can be supported. The armrest device 102 is in particular a component of a center armrest of a motor vehicle. The guide device 100 is provided, for example, in single or double manufacture. In particular, two guide devices 100 are provided, which together form a guide system 104 of the armrest device 102.

The guide devices 100 are aligned parallel to one another.

In the embodiment of the guide device 100 shown in FIG. 1, it comprises in particular a first guide rail 106 and a second guide rail 108, the first guide rail 106 and the second guide rail 108 being movable relative to one another by means of a bearing device 110.

The bearing device 110 comprises in particular a plurality of rolling elements 112 which are positioned relative to one another by means of a rolling element cage 114 and roll on rolling element raceways 116 of the guide rails 106, 108.

Each guide rail 106, 108 comprises a rail back 118, which binds two legs 120 of each guide rail 106, 108 together.

The legs 120 in particular have the rolling element raceways 116.

In the embodiment of the armrest device 102 shown in FIG. 1, a cover plate 122 is provided, by means of which the two second guide rails 108 of the guide devices 100 are firmly coupled to one another. The two first guide rails 106 of the guide devices 100 are fixed, for example, to an armrest receptacle (not shown) and are thus firmly connected to one another.

The two guide devices 100 can thus only be actuated together in the embodiment shown in FIG. 1 of the armrest device 102, in particular can be moved back and forth between two end positions of the guide devices 100.

The cover plate 122 is in particular fixed on the rail back 118 of the second guide rails 108 of the guide devices 100.

As can be seen in FIG. 1, the second guide rail 108 of each guide device 100 is designed to be shorter than the first guide rail 106.

In particular, the second guide rail 108 has a length along a direction of movement 124 of the guide device 100 which corresponds at most to approximately 60%, for example at most approximately 50%, to a length of the first guide rail 106.

The bearing device 110, in particular the rolling bodies 112 and the rolling body cage 114, is preferably designed, arranged and dimensioned such that the second guide rail 108 is at least approximately uniform over its entire length at all conceivable positions along the entire movement path between two end positions over its entire length is mounted on the first guide rail 106 by means of roller bodies 112. In particular, the second guide rail 108 does not protrude beyond the bearing device 110 and / or the first guide rail 106 along the direction of movement 124. This enables a particularly stable configuration of the guiding device 100 to be achieved. It may be advantageous if the rolling element cage 114 is longer than the second guide rail 108 in a direction running parallel to the movement path of the second guide rail 108. The guide device 100 is then in particular a rotor guide.

An alternative embodiment of a guide device 100 shown in FIG. 2 differs from the embodiment shown in FIG. 1 essentially in that the guide rails 106, 108 have at least approximately the same length along the direction of movement 124.

The guide rails 106, 108 can thus be arranged, for example, in an overlapping position according to FIG. 2 or also in an extended position (not shown), in which the second guide rail 108 via the first guide rail 106 or the first guide rail 106 via the second guide rail 108 protrudes along the direction of movement 124.

2 also shows assembly elements 126, by means of which the guide device 100 can be fixed.

Otherwise, the alternative embodiment of the guide device 100 shown in FIG. 2 corresponds in structure and function to the embodiment shown in FIG. 1, so that the previous one is shown

Description so far.

FIG. 3 shows a schematic longitudinal section through a guide device 100, which essentially corresponds to one of the guide devices 100 shown in FIG. 1, but whose internal structure can also be provided, for example, in the guide device 100 shown in FIG. 2.

As can be seen in FIG. 3, the guide device 100 preferably comprises a coupling device 128, which in particular in an intermediate the guide rails 106, 108 formed space 130 of the guide device 100 is arranged.

The coupling device 128 in particular comprises a coupling element 132.

The coupling element 132 enables, in particular, a mechanical coupling of the first guide rail 106 to the second guide rail 108, this coupling being different from the coupling achieved by the bearing device 110.

The coupling device 128 is in particular a device that is different and / or spatially separate from the storage device 110.

The coupling element 132 preferably comprises a spring part 134, which comprises a fastening section 136, a connecting section 138 and a receiving section 140. In particular, a positive and / or integral connection, for example a riveted connection and / or welded connection, is provided for fixing the fastening section 136 of the spring part 134 to a rail back 118 of one of the guide rails 106, 108.

The spring part 134 is fixed to one of the guide rails 106, 108 by means of the fastening section 136. In particular, the spring part 134 is fixed to a rail back 118 of one of the guide rails 106, 108 by means of the fastening section 136.

The receiving section 140 of the spring part 134 serves to receive a contact part 142, which will be described in more detail below.

The connecting section 138 of the spring part 134 connects the fastening section 136 to the receiving section 140. The fastening section 136, the connecting section 138 and the receiving section 140 of the spring part 134 are produced in particular by stamping and / or bending or other shaping from a metal sheet or as a component from sheet metal and / or plastic. In particular that is

Spring part 134 is a metal sheet component. The geometrical details relevant for optimizing the function of the spring part 134 will be discussed in more detail.

The contact part 142 forms in particular a friction element 144 and / or a locking element 146.

By means of the spring part 134 and the contact part 142 can thus be achieved in particular a friction effect and a locking or other locking between the two guide rails 106, 108.

For this purpose, the contact part 142 in particular comprises one or more friction surfaces 148 and one or more locking projections 150. As an alternative to one or more locking projections 150, locking depressions (not shown) can also be provided.

The spring part 134, in particular the connecting section 138 of the spring part 134, preferably extends obliquely through the intermediate space 130, for example at an angle of less than 20 °, preferably less than 15 °, relative to the direction of movement 124.

In particular, a main direction of extent 152 of the connecting section 138 of the spring part 134 with the direction of movement 124 includes an angle of at most approximately 20 °, for example at most approximately 15 °.

By suitably shaping the coupling element 132, in particular the spring part 134, a predetermined contact pressure can preferably be achieved, by means of which the contact part 142 can be attached to one of the guide rails 106, 108, in particular on a rail back 118 of one of the guide rails 106, 108, is pressed.

To generate and / or to set this pressing action more precisely, the guide device 100 preferably comprises an actuating element 154 which is accommodated by means of an actuating element receptacle 156 and in particular can be fixed in different positions in the actuating element receptacle 156.

The actuating element receptacle 156 is, in particular, a passage opening 158 in a rail back 118 of one of the guide rails 106, 108.

The passage opening 158 is seen in particular with an internal thread 160 ver.

The actuating element receptacle 156 preferably has a collar 162 fixed to the rail back 118, molded thereon or molded out of the rail back 118, whereby a length of an internal thread 160 in the passage opening 158 can preferably be increased, in particular in comparison to a length of an internal thread 160, if this would only extend beyond the material thickness of the rail back 118.

Alternatively or in addition to one from the rail back 118

The collar 162 formed out can be provided, for example, with a press-in nut or some other additional component in the rail back 118 for producing an internal thread 160 in the passage opening 158.

The adjusting element 154 is designed in particular as a grub screw or another screw element.

The actuating element 154 can be arranged, in particular fixed, in the actuating element receptacle 156 in different screw-in depths, and thereby projects different distances into the space 130 between the guide rails 106, 108.

In particular, the actuating element 154 projects up to the coupling element 132 into the intermediate space 130 and acts, for example, on the connecting portion 138 of the spring part 134.

A spring action of the spring part 134 and / or a pressure action of the contact part 142 can thus preferably be generated and / or set by means of the adjusting element 154.

3, the coupling element 132 does not extend in a direct way from one of the guide rails 106, 108 to the other.

Rather, the coupling element 132 extends along the

Direction of movement 124 such that an offset V along the

Direction of movement 124 between a center point of the fastening portion 136 and a center point of the contact part 142 results.

The offset V is in particular at least approximately 20%, in particular at least approximately 50%, of a maximum movement path of the guide rails 106, 108 relative to one another. As a result, a long leverage effect of the coupling element 132 and / or an exact one can be achieved

Adjustment of the contact pressure can be achieved.

4 to 8 are further details of the coupling element 132 Darge provides.

The spring part 134 is produced in particular as a sheet metal component in a stamping and / or bending process. The contact part 142 is in particular a plastic component, for example made of polyoxymethylene (POM).

The contact part 142 is in particular injection molded onto the spring part 134 or fixed to it by locking. As can be seen in particular in FIG. 6, the connecting section 138 of the spring part 134 has a smaller width B in a transverse direction 164 running perpendicular to the direction of movement 124 than the fastening section 136 of the spring part 134. In particular, the width B of the connecting section 138 is at most approximately 90 %, preferably at most about 85%, of a width B of the fastening section 136.

The contact part 142 is preferably in the transverse direction 164 beyond the connecting portion 138 in addition. In particular, the contact part 142 preferably surrounds the receiving section 140 on at least four sides, preferably five sides.

The contact part 142 forms in particular an end cap 166 for the spring part 134.

5, the contact part 142 comprises two friction surfaces 148 and a locking surface 168 formed by the locking projection 150.

The friction surfaces 148 are formed in particular by two along the direction of movement 124 extending friction rails 170.

The friction rails 170 extend in particular essentially perpendicular to the locking projection 150, which extends in particular in a web-like manner between the friction rails 170.

The locking projection 150 is preferably set back relative to the friction rails 170 with respect to a pressing direction 172 running perpendicular to a surface of the rail back 118, so that the latching surface 168 is set back in particular with respect to the friction surfaces 148. The latching surface 168 thus does not come into contact with this guide rail 106, 108 when achieving a friction effect on one of the guide rails 106, 108 by means of the friction surfaces 148. Rather, the locking projection 150 and thus also the locking surface 168 formed thereby, for example, only with a further locking projection 150, which is formed on one of the guide rails 106, 108, in order to ultimately lock the guide rails 106, 108 relative to one another, for example to snap.

Such a locking projection 150 of a guide rail 106, 108 is shown in particular in Fig. 3 in particular.

The locking projection 150 is in particular designed such that the friction rails 170 forming the friction surfaces 148 can be moved laterally past the locking projection 150 of the guide rail 106, 108 in the transverse direction 164, without coming into contact with the locking projection 150 or in any other way.

As can be seen in particular in FIG. 8, the locking projection 150 of the contact part 142 is essentially rounded. In particular, successive, at least approximately identical radii are provided for forming the locking projection 150. For example, a concave radius is followed by a convex radius and then again by a concave radius in order to form the locking projection 150.

The friction surfaces 148 can be formed, for example, parallel to the surface of a rail back 118 of one of the guide rails 106, 108.

However, it can be advantageous if the friction surfaces 148 along the

Direction of movement 124 and / or along the transverse direction 164 are formed from curved. In this way, an optimized friction effect can preferably be achieved and / or undesired tilting of the contact part 142 can be prevented. Furthermore, this can preferably result in undesired scraping or other removal of a lubricant can be avoided or reduced.

An alternative embodiment of the contact part 142 of the coupling element 132 shown in FIG. 9 differs from the embodiment shown in FIG. 8 essentially in that two locking projections 150 are provided for locking, which in particular have a locking projection 150 on a counterpart 174, for example on the Rail back 118 can accommodate between them. In particular, an intermediate or central detent between two end positions of the

Guide rails 106, 108 can be realized relative to each other.

The locking projections 150 of the contact part 142 can, for example, have identical heights in order to achieve identical unlocking forces in both directions of movement parallel or antiparallel to an extension direction (parallel to the path of movement).

As an alternative to this, however, it can also be provided that the locking projections 150 of the contact part 142 are dimensioned differently, in particular have different heights along the pressing direction 174. In this way, different unlatching forces can be achieved for unlatching in different directions.

Otherwise, the alternative embodiment shown in FIG. 9 corresponds to that of the contact part 142 in terms of structure and function with the embodiment shown in FIG. 8, so that reference is made to the above description thereof.

Due to the fact that the guide device 100 comprises a coupling device 128, which comprises a coupling element 132 with a contact part 142, a comfortable and haptically appealing actuation of the guide device 100 and thus also of the device can preferably

Armrest device 102 can be achieved. In addition, for example the use of a contact part 142 forming a friction element 144 prevents an automatic shifting of an armrest of the armrest device 102, which is undesirable when a vehicle is in operation.

Through the use of the described spring part 134 and / or the additional union adjusting element 154, a particularly uniform and / or long-term stable friction and / or locking action can also be ensured.

An alternative embodiment of a coupling device 128 shown in FIG. 10 differs from those described above

Embodiments essentially in that the contact part 142 of the coupling element 132 interacts with a counterpart 174 which has, for example, differently positioned sections 176.

The counterpart 174 is in particular a rail back 118, for example the rail back 118 of the first guide rail 106. In particular, the counterpart 174 is molded into the rail back 118 or formed by shaping the rail back 118.

However, it can also be provided that the counterpart 174 is an additional component which is arranged in particular on a rail back 118, for example on the rail back 118 of the first guide rail 106.

The counterpart 174 preferably comprises a plurality of sections 176 which, for example, each extend along a movement path of the second guide rail 108 and / or parallel thereto and / or along a contact path of the contact part 142 and / or parallel thereto.

Each section 176 preferably forms a plateau on or along which or parallel to which the contact part 142 is displaceable.

Two or more than two sections 176 are arranged in mutually different positions parallel to the pressing direction 172. In particular, they are two or the more than two sections 176 are arranged at different heights or depth levels.

The coupling device 132 thus acts locally differently along the direction of movement 124 on the relative movement of the guide rails 106, 108, in particular due to a locally different deflection of the spring part 134 (not shown in FIG. 10).

It can be provided that the contact part 142 comes into contact or can be brought into contact with only one, only two or more than two sections 176, in particular when the guide rails 106, 108 move relative to one another from one end position to another end position.

In particular, it can be provided that the contact part 142 does not come into contact or cannot be brought into contact with one or more sections 176, in particular when the guide rails 106, 108 move relative to one another from one end position to another end position.

For example, it can be provided that the contact part 142 only comes into contact or cannot be brought into contact with a section 176e which is arranged in an end region of a movement path of the guide rails 106, 108. As a result, the guide rails 106, 108 can in particular be locked relative to one another by friction between the contact part 142 and said section 176.

As an alternative or in addition to this, one or more locally raised sections 176a can be provided, each of which is positioned further along the pressing direction 172 in the direction of the contact part 142 than two arranged on both sides of the respective locally raised section 176a

Sections 176. This allows a between two end positions of the

Guide rails 106, 108 arranged intermediate locking or at least an area with increased movement resistance can be achieved. Incidentally, the alternative embodiment shown in FIG. 10 corresponds to that of the coupling device 132 in terms of structure and function as desired with each of the above-described embodiments, so that reference is made to the above description in this regard.

Alternatively or in addition, in particular for local variation of the

Action of the coupling device 132 on the relative movement of the

Guide rails 106, 108 can be provided that the counterpart 174 comprises a plurality of sections 176, which differ from one another in terms of material and / or in terms of their shape or surface structure.

In particular, a plurality of sections 176 are provided, which have different coefficients of friction from one another, so that different contact friction forces and / or occur upon contact with the contact part 142

Result in sliding friction forces.

Two or more than two of these sections 176 can, for example, be arranged in different positions parallel to the pressing direction 172. Alternatively or in addition, one or more, in particular all, of these sections 176, which have mutually different coefficients of friction, can also be arranged in a common plane.

The plane is in particular perpendicular to the pressing direction 172

aligned.
