Description

guiding device

The present invention relates to a guide device for a Schubele element, with a pull-out guide having at least two rails, where the rails are held movable relative to one another, in particular via rolling elements, and a pull-in device or pull-out device fixed on a first rail, which with a on a second rail fixed actuator can be coupled in order to retract the pull-out guide in a range of motion into a closed position or to pull it out and hold it in an open position, the pull-in device or pull-out device having a driver biased by an energy accumulator which along a guide path between a pull-in position or Pull-out position and a parking position with tensioned energy storage is movable. In the case of a pull-out device, the second rail is moved automatically, preferably damped, relative to the first rail into a maximum opening position.

EP 2 445 376 B1 discloses a self-closing device which is mounted on a pull-out guide. The self-retracting device comprises a housing on which a track for a driver is formed, which can be moved from a retracted position to a parking position with a tensioned energy store. From the park position, an activator on a movable rail can engage the driver to release it, so that the movable rail is moved with the activator into the closed position or open position. Such self-retracting devices are often installed in furniture that is already installed, although other building activities are taking place in the rooms. The construction work usually creates a lot of dust, which also deposits on the furniture and fittings of the furniture. If the dust reaches the guideway for the driver of the self-retracting device or self-pulling device, there may be increased friction and squeaking noises.

Even when using a corresponding pull-out guide in a household appliance, for example in a dishwasher, the guide track for the driver of the self-retracting or self-pulling device can be contaminated by food residues or detergent residues, which can also lead to increased friction and squeaking noises. It is therefore an object of the present invention to provide a guide device for a thrust element which provides improved protection against contamination.

This object is achieved with a guide device with the features of claim 1.

In the guide device according to the invention, the pull-in device or pull-out device has a housing within which the guide track is arranged in a protected manner for the driver. As a result, the dust can settle on the outside of the housing of the feed device or pull-out device, but the guideway is protected by the housing and can therefore also ensure smooth movement of the driver if the housing is contaminated on the outside. Although a slight gap between the rails of the pull-out guide and the housing is necessary due to the coupling of the driver with the activator, the dust input is nevertheless reduced by the fact that the housing surrounds the guideway, and in particular the area above the guideway is covered by the housing is.

The guideway is preferably arranged so that it is not visible from the outside, at least in a closed position of the pull-out guide. The guideway is located in an interior of the housing, which is covered by the housing. The guideway can be surrounded by the housing on at least three sides, in particular also on four or five sides, the pull-out guide covering the interior of the housing on one side.

As a result, the guideway can be protected particularly effectively against contamination.

The guideway is preferably formed on at least one web projecting into the interior of the housing. The web can be designed in the form of strips, the driver engaging behind the web or a guide bar spaced apart from the web and thus being secured against lifting off. Preferably, a wall portion on which the guide track is formed is aligned vertically. On such a vertical wall section bad contaminants settle. The driver can also be pivoted in a vertical direction along the guideway shortly before reaching the closing position or opening position, so that the Movement of the driver takes place in a vertical plane, which reduces the susceptibility to contamination.

For easy assembly, the driver can have two pins which are slidably held on the guideway. In addition, a web can be formed on the driver, which engages behind a guide web on the housing in order to be able to preassemble the driver on the housing.

The housing of the pull-in device or pull-out device is fixed on the stationary rail vorzugswei se, while the activator is fixed on a moveable rail. As a result, the housing can be arranged inside a Möbelkor pus, which improves protection against contamination even when opening the pull-out guide. Alternatively, the housing can also be arranged on a movable rail and, accordingly, the activator on the fixed rail.

For simple assembly and disassembly, the housing can be clipped onto a rail of the pull-out guide using a snap-in connection. For this purpose, two hook-shaped webs can be formed on the pull-out guide, for example, on which the housing can be inserted or pivoted. There may also be more than two webs or further fastening interfaces. For example, a web or a projection for holding the housing can be present in the middle between the two hook-shaped webs. The activator can also be clipped on to the other rail without tools. The activator is preferably made of plastic.

In the method according to the invention, a pull-out guide with at least two rails which can be moved relative to one another is first provided, two hook-shaped webs being provided on one rail. Then one end of a housing of the retraction device or Auszugvorrich device is inserted in the longitudinal direction of the rail on a first hook-shaped curved web, in order to then pivot the housing of the retraction device or pull-out device about an axis of rotation formed by the first hook-shaped curved web and thereby a wall section of the Ge housing on the second hook-shaped web to insert up to a stop in order to fix the housing by clamping or latching on the rail. The invention is explained below using an exemplary embodiment with reference to the accompanying drawings. Show it:

A guide device 1 comprises a pull-out guide 2, which has a stationary rail 3, which can be fixed to a furniture body or a household appliance via angular holders 4. As can be seen in particular in FIG. 1B, the stationary rail 3 is connected to the angular holders 4 at joints 40 by means of clinching. There is no material on the joints 40 on a surface 41 on the underside of the holder 4, which prevents the pull-out guide 2 from tipping during transport and storage. On the stationary rail 3, a middle rail 5 is held movable over rolling elements, and on the central rail 5 a movable rail 6 be held movable over rolling elements. A push element, such as a drawer or a food support, can be attached to the movable rail 6.

In order to be able to move the pull-out guide 2 in the closing direction before reaching a closed position, a pull-in device 10 is provided which has a housing 11 which is fixed to the stationary rail 3. It would also be possible to attach the housing 1 1 of the feed device 10 to the movable Fix rail 6. The housing 1 1 is fixed to two hook-shaped webs NEN 12 of the rail 3 by a snap connection. In addition, the housing 1 1 has two locking webs 1 1 1, which snap into recesses 301 on the stationary rail 3.

In Figure 2, the pull-out guide 2 is shown without a feed device 10. It can be seen that two openings 30 are formed on the movable rail 6 and are used to mount an activator 31. The activator 31 is formed by two projections which protrude from a plate 32. The plate 32 is placed on the movable rail 6, and holding webs 33 or pins are formed on the side opposite the activator 31, which ensure that the activator 31 is fixed in a clamped or latching manner on the movable rail 6.

The mounting of the activator 31 on the movable rail 6 is shown in FIGS. 3A to 3C. The activator 31 is inserted with the retaining webs 33 in the openings 30 and then pivoted in order to fix the activator 31 on the rail 6.

In Figure 4, the assembly of the housing 1 1 on the stationary rail 3 shows ge. The stationary rail 3 comprises two hook-shaped webs 12, the tips of the webs facing one another. On the first hook-shaped web 12, the housing 11 is pushed in, while on the second hook-shaped web 12, the housing 11 is pivoted about a horizontal axis which is formed by the first hook-shaped web 12. For this purpose, the housing 1 1 has a receptacle 1 12 at one end and only one latching edge 1 13 at the other end, which arrives at the second hook-shaped web 12 from above. Here, a wall section of the housing 11 on the second web 12 is inserted between a wall of the rail 3 and the projecting hook-shaped web 12 until it stops. The housing 1 1 can be fixed in a clamped or latching manner on the stationary rail 3. In the middle between the two hook-shaped webs 12, there is an additional hook-shaped web 121 on the rail 3 for holding the housing 11 in the assembled state.

In FIGS. 5A and 5B, the feed device 10 is shown without the pull-out guide 2. The housing 1 1 is substantially strip-shaped ausgebil det and has on a side facing an interior a guide track 13 which is formed on a vertical wall portion of the housing 1 1 is. The guideway 13 has an angled end section 14, on which a driver 15 can be held in a parking position. The driver 15 is tensioned in the closing direction before by an energy accumulator 16 in the form of a spring. The energy accumulator 16 is arranged in a first receptacle of the housing 1 1, and parallel to the receptacle, a second receptacle with a linear damper is provided, which has a damper housing 17 and a displaceable piston rod, which has a connecting element 18 with the driver 15 is coupled. A closing movement of the driver 15 can thereby be braked.

Spaced from the guideway 13, a guide web 25 is formed next to a guide slot 26 in the housing 11, in which a guide element 22 of the driver 15 engages to secure the driver 15 against lifting from the housing 11. The guideway 13 is groove-shaped with a bottom so that no contamination by dust can get into the guideway 13. The narrow guide slot 26 is of fen formed so that it can be penetrated by the guide element 22, the guide slot 26 having a widening at the end to enable pivoting of the driver 15 in the region of the angled Endab section 14. It is also possible to also close the guide slot 26 and to provide security against lifting the driver 15 by means of a hook-shaped guide web.

The driver 15 is shown in detail in FIGS. 6A and 6B. With the participant 15 comprises two pins 21 which are slidably arranged in the guideway 13. A guide element 22 is formed at a distance from the pins 21, which extends through the guide slot 26 and engages behind the guide web 25 so that the driver 15 is secured against being lifted off the guide track 13.

Furthermore, a receptacle 19 for coupling to the Li near damper and a further receptacle 20 for connection to the Kraftspei cher are provided on the driver 15. In addition, there is a receptacle 23 for coupling to the actuator 31 on the driver 15.

In the assembled position, the guideway 13 is arranged by the housing 11 protects ge, the guideway 13 facing an interior, which is covered on five sides by the housing 1 1. The pull-out guide 2 with the rails 3, 5 is in the assembled position on the sixth side and 6 are provided for covering, so that contamination can still occur due to small gaps, but the contamination is significantly lower compared to an unprotected arrangement of the guideway. At least the area above the guideway 13 is covered by the housing 1 1 and prevents the accumulation of dust on the guideway.
