Description

pusher assembly

The present invention relates to a thrust assembly with two fixed to opposite side walls pull-out guides, each rail a stationary guide rail, a movable mounted on the guide rail means and comprise a movable rail mounted on the center rail, wherein a first thrust element on the two rails of the two Pull-out guides is kept, as well as a household appliance and a piece of furniture.

DE 10 201 1 050 523 shows an extension system in which a first push element is movably mounted on a pullout guide, which is connected via a transmission with a second pullout guide on which a second push element is held. As a result, when moving the first pushing element, the second pushing element can also be moved. However, the use of two pullout guides and a gear is comparatively expensive. Especially in household appliances also prevail cramped space conditions that complicate the installation of an extension system with two pullout guides and a transmission.

It is therefore an object of the present invention to provide a thrust assembly which has a compact design and enables effective movement of two pushers. To solve this problem, a thrust assembly with the features of claim 1 is proposed.

According to the invention, two pull-out guides are provided which can be fixed to opposite side walls of a furniture carcass or household appliance, a first push element being held on the two rails of the two pull-out guides and a second push element being held on the two middle rails of the two pull-out guides. As a result, a method of two push elements can be achieved with only two pull-out guides. Due to the relative movement of the running rail to the middle rail, the pusher elements are moved at different speeds and with different travel distances.

Synchronizing means are preferably provided on at least one pull-out guide in order to enable the movement of the running rail to the middle rail synchronize. Preferably, the rails are moved at about twice the speed to the center rails and also lay back twice the distance. For synchronization, in each case a cable pull can be provided on at least one pull-out guide, preferably on both pull-out guides. The cable can be guided over pulleys, which are fixed to the center rail, so that is ensured by a determination of the cable to the running rail and the guide rail, that the movement of the running rail is synchronized to the center rail, thus avoiding slippage between running rail and center rail becomes. Other types of synchronization means, such as toothed gearing or chain transmissions, may also be used.

According to a further embodiment, the first push element on holders on the running rail and / or the second push element on holders of the middle rail can be reversibly fastened, in particular can be suspended or placed on. As a result, the pushers can be easily assembled or disassembled. The first thrust element is preferably arranged under the second thrust element and can for example be hung on holders, in particular angle-shaped holders. The upper second thrust element can be placed on holders, for example on connecting rods, which are provided between the two middle rails. The connecting rods can also synchronize the right and left pullout guide in their movement. The push elements can also be designed so that the first push element can be placed on the holder and the second push element can be hooked into the holder.

Alternatively, the holder may be formed as a peripheral frame, for example, for waste containers, or as a plate to accommodate containers regardless of the outer contour can. The plate could advantageously have adjustable locking elements, which could be flexibly adapted to the respective contour of the container.

Preferably, on the lower first pusher element, an actuator is provided on the front side which projects upwards. The actuating element can be fixed on opposite sides on the running rail and thus controls the movement of the lower pushing element without the user having to bend completely to the lower pushing element. The actuating element can at least partially protrude beyond a front side of the upper second pushing element, so that the actuating element is a gripped and used to move the two pushers. The actuating element may be formed, for example, as a U-shaped bracket, the upper connecting element forms a handle which is disposed over the second thrust element.

For ease of use, the pusher elements can be designed as drawers, for example, as drawers made of plastic, which can be used and removed on the pullout guides. The lower first thrust element is preferably shorter in the longitudinal direction of the drawer guide than the upper second thrust element, in particular by at least 20%, for example by at least 40%. This ensures access even in the rear region of the lower push element, if the push arrangement is not arranged completely in the pulled-out position, which simplifies handling. In addition, due to the shortened design of the space back of the lower thrust element can be used elsewhere.

The two pullout guides are preferably mounted so that the movable track rail is disposed below the stationary guide rail. Angle-shaped holders for holding a pushing element can then be fixed on the running rail.

The invention is preferably used in household appliances, in particular refrigerators, wherein the thrust arrangement, for example, stores the two lower drawers of a refrigerated compartment in a movable manner. Other applications, such as furniture or other household appliances, are possible. It is also possible that the first thrust element above the second

Push element is arranged, for example, in sink or Waschbeckenunterschränken. In this case, the running rail is then arranged above the guide rail. The invention will be explained in more detail with reference to the accompanying drawings. Show it:

FIGS. 6A to 6C show several views of the drawer slide guides in a maximum pull-out position, and FIGS

Figure 7 is a plan view of the thrust assembly of Figure 3 in egg ner maximum extension position. A piece of furniture or household appliance 1 comprises a body 2, for example a body of a refrigerating compartment of a refrigerator or of a refrigerator-freezer combination, which has two side walls 3 on which a pushing arrangement 4 is mounted. The thrust assembly 4 can be mounted directly on the side walls 3 or via other fasteners.

The thrust assembly 4 comprises a lower first thrust element 5 and an upper second thrust element 6, which are each designed as drawers and for the storage of objects, such as food, serve. Provided on the lower push element 5 is an actuating element 7, which is designed as a U-shaped bracket and has two vertical legs 70 and a connecting element 71 which is arranged in the closed position above a front side of the upper push element 6. Thereby, the connecting member 71 can be easily gripped to move the pushing assembly from a closed position to an opening direction.

In Figure 2, the thrust assembly 4 is moved in a partially open position outside of the body 2. For this purpose, in the thrust arrangement 4 at opposite Overlying sides pullout guides 10 provided by means of which the pushers 5 and 6 are moved.

In Figure 3, the thrust assembly is shown in a maximum extension position. The lower first thrust element 5 is now completely in front of the upper second thrust element 6, so that access is ensured from above into the interior of both the lower first thrust element 5 and the upper second thrust element 6. In FIGS. 4A to 4D, the drawer guides 10 of the thrust assembly 4 are shown in detail in the closed position. Each pullout guide 10 comprises a stationary guide rail 1 1, a rail 12 movably mounted on the guide rail 1 1 and a running rail 13 movably mounted on the center rail 12. Rolling bodies or rollers can be provided for movably supporting the center rail 12 and the running rail 13 ,

The guide rail 1 1 is fixed via mounting bracket 14 on the side walls 3 or connected to the side walls 3 components. In order to ensure that the first push element can be moved with the running rail 13, holders 15 are provided on each running rail 13, in particular angle-shaped holders 15, so that the first push element 5 can be attached to the holders 15. Above the holders 15, the middle rails 12 are connected to one another via two holders in the form of connecting rods 16, and the second pushing element 6 can be placed on the two connecting rods 16 and fixed. The connecting rods 16 cause a

Synchronization of the movement of the left pullout guide 10 with the right pullout guide 10th

In order to obtain a synchronized movement of the running rail 13 and the center rail 12, in which the running rail 13 is moved at about twice the speed to the center rail 12, a synchronization means, in the embodiment as a traction means and explicitly designed as a cable 23, is provided. The cable 23 is guided circumferentially on pulleys 21 and 22. The deflection rollers 21 and 22 are rotatably mounted on the central rail 12. The cable 23 is formed interrupted, wherein the one ends of the cable 23 are held on a first connecting element 24 on the running rail 13 and the other ends to a second connecting element 30 which is fixed to the guide rail 10. It can be seen in FIG. 4C that the pull-out guide has a self-closing device 20 in the area of the center rail 12, which biases the push arrangement 4 into a closed position, at least in a region shortly before the closed position. The Selbsteinzugsvorrichtung 20 may also include a damper to decelerate the closing movement of the thrust assembly 4.

In FIG. 4D, the first connecting element 24 is shown in order to fix a first end 26 of the cable pull 23 to a bent-over section 25. Adjacent to the bent portion 25, a second bent portion 27 is provided on the connecting member 24, on which a second end 28 of the cable 23 is held. In a similar manner, two ends of the cable 23 are respectively fixed to the second connecting element 30, so that during a movement of the running rail 13 in the extension direction of the cable 23 is moved over the pulleys 21 and 22 and thereby ensures that the center rail 12 with the half Speed as the track 13 is moved.

In FIGS. 5A to 5C, the pullout guides are in a central pullout position. It can be seen that the guide rail 1 1 remains stationary in the body 2, while the center rail 12 and the running rail 13 are moved out of the body 2. The holder 15 is arranged below the connecting rods 16, while the upper second thrust element 6 is placed on the connecting rods 16, so that the thrust elements 5 and 6 can be moved relative to each other.

In FIGS. 6A to 6C, the pullout guides 10 are arranged in a complete pullout position. The holders 15 on the rails 13 are located with the first push element 5 far in front of the body 2, as shown in Figure 3. Also, the center rail 12 is located largely in front of the body 2, so that access to the upper thrust element 6 is ensured.

If the thrust assembly 4 is now moved back into the closed position, the user pushes only the upwardly projecting actuator 7 in the closing direction, so that the two slide guides 10 run automatically in the closing direction. Before the closing position is reached, the self-closing device 20 then optionally effects a deceleration via an integrated damper and a self-closing mechanism up to the closed position, which is shown in FIG. In Figure 7, the maximum extension position of the thrust assembly is shown in a view from above. The first lower pusher element 5 is located completely in front of the upper second pusher element 6, so that access from above is readily possible. The lower first thrust element 5 is formed shorter than the upper thrust element 6, preferably about half as long as the upper thrust element, so that the space in the body 2 can be used for other purposes, such as the use of a compressor in a refrigerator , The upper thrust element 6 is over 60%, in particular more than 70%, arranged in front of the body 2, so that objects can be removed easily. The first push element 5 has, for the reversible fixation on the holders 15 on both sides, a specially formed edge region 50, which corresponds to the shape of the holder 15. The second pusher 6 is placed on the connecting rods 16, that the projections 60 are shown at the bottom, which are shown here in dashed lines, respectively on both sides of the connecting rods 16, and thus the pusher 6 on the rods against lateral slipping and against secure a tilting movement. In this case, the distances of the projections 60 to each other from the bottom to the top down, so that on the one hand a slight Ineingriffgelangen the projections 60 with the connecting rods 16 is possible and on the other hand in the mounted end position a positive connection between projections 60 and connecting rods 16 is present ,

It is also possible that the holder for at least one of the thrust elements 5, 6 are formed as a peripheral frame or as a plate. Alternatively, the thrust elements 5, 6 could themselves have holding elements, whereby they could be fastened directly to the drawer guides 10. It is also within the scope of the possible that the pushers 5,6 are firmly connected to the pullout guides 10.

In the illustrated embodiment, the thrust assembly 4 is used in a cooling device. It is of course also possible to use the thrust assembly for other purposes, such as furniture or other household appliances such as dishwashers or warm drawers. LIST OF REFERENCE NUMBERS
