This simplifies handling.

Description

Furniture

The present invention relates to a piece of furniture with a furniture body and a first pusher element which is held movably relative to the furniture body and has a front panel, and a second pusher element which is held movably relative to the furniture body and which, in a closed position of the first pusher element in the direction of travel, is at least partially behind the front panel of the first thrust element is arranged, and a coupling mechanism with which the first thrust element can be coupled to the second thrust element at least over a part of the travel path in order to move it in the extension direction.

EP 3 698 093 B1 discloses a device for storing objects in which two push elements can be connected and moved together via a coupling mechanism. Via the coupling mechanism, the second pusher element is moved at the same speed as a middle rail of a pull-out guide for moving the first pusher element. This means that the two thrust elements can be coupled for a common movement, although it is not possible for the user to influence the opening speed of the second thrust element.

It is therefore the object of the present invention to create a piece of furniture in which the handling of the movement of two push elements is designed to be more flexible.

This task is solved with a piece of furniture with the features of claim 1.

In the furniture according to the invention, two thrust elements can be coupled to one another via a coupling mechanism at least over part of their travel path in order to be movable in the extension direction, the coupling mechanism having at least one flexible tension element with which the second thrust element can be driven in the extension direction by the first thrust element , when the first pushing element is at least partially moved in the extension direction. As a result, the user can initially move the first thrust element from the closed position in the opening direction independently of the second thrust element until the second thrust element can be driven in the extension direction by the first thrust element via the flexible tension element. The The second thrust element is therefore not driven in the opening direction over the entire range of movement of the first thrust element, but only from a predetermined opening position of the first thrust element. This means that the user can also use the first thrust element to influence the speed of the second thrust element in the extension direction, depending on how hard the first thrust element is pulled in order to drive the second thrust element, which makes handling more flexible. When opening the first thrust element, the user can influence whether the second thrust element remains in the closed position, is partially moved in the extension direction or is completely extended.

The offset opening of the second thrust element only when the first thrust element is already in an opening position, for example only after an opening path of at least 10cm, leads to the advantage that when opening the first thrust element only the force of a first self-closing for the first thrust element is overcome and only then does the force to pull up a second self-closing mechanism have to be applied to the second thrust element. It can thus be avoided that both self-closing mechanisms have to be wound up at the same time, which requires a lot of effort. The self-closing mechanisms each include a driver which can be moved along a curved guide and is prestressed by an energy accumulator and which can be locked on an end section of the curved guide.

The term “furniture” used here includes furniture for storing objects, for example cupboard furniture or kitchen furniture. However, the furniture can also be designed as household appliances, which thus form furniture with an additional function, for example for heating or cooling objects or food. The term “furniture” should also include such household appliances.

Preferably, the at least one flexible tension element is fixed to the first thrust element and the second thrust element or held along a guide, for example a sliding guide or a roller guide. The at least one flexible tension element can be designed as a rope or band, for example as a wire rope to transmit high forces or as a slightly elastic rope or band to reduce shock loads.

The first push element can preferably hang the at least one flexible tension element downwards when moving in the opening direction. tension the loop-shaped position into a linear shape. In this case, the at least one flexible tension element can be aligned essentially parallel to the direction of travel in the tensioned position in order to avoid transverse forces on the second push element, which can be moved linearly on pull-out guides, for example. Alternatively, the flexible tension element can be wound up pre-stressed in the inserted position on a body, for example a drum, by at least one energy accumulator, in particular a roller spring, from which it is unwound during the movement of the first thrust element until it reaches the tensioned position. Of course, other types of storage are also conceivable that avoid loop-shaped sagging. This storage, in particular rope storage, can be set up on both the first and second furniture part.

Furthermore, the flexible tension element can be fixed in an adjustable length between a first connecting part and a second connecting part, so that the user can set the extension position from which the first pushing element drives the second pushing element.

In a first embodiment, the flexible tension element can be fixed via a first connecting part in the rear region, in particular on a rear wall, of the first thrust element, for example in a central region between two side walls of the thrust element. In addition, the flexible tension element can be fixed via a second connecting part in the rear area, in particular on a rear wall or the bottom of the second push element, with the introduction of force preferably also taking place in the middle. The alignment of the flexible tension element in the tensioned position can be adjusted via the connecting parts, for which purpose the first and/or the second connecting part can be designed to be adjustable in height. Due to the arrangement of the flexible tension element in the rear area of the thrust elements, they are not visible to the user even when opening the thrust elements.

In a second embodiment, the at least one flexible tension element is fixed at opposite ends to the second thrust element and connected to the first thrust element via a sliding guide. Two flexible tension elements can preferably be provided, through which the second thrust element can be driven by the first thrust element. The two tension elements can be arranged, for example, in the area of the side frames of the push elements, and the length of the two tension elements is thus on top of each other coordinated so that the second push element is preferably pulled out of the closed position at the same time by both tension elements. This embodiment has the advantage that the second thrust element can also be driven in the closing direction via the at least one flexible thrust element, without a front panel or another driver component of the first thrust element striking against the second thrust element.

The second push element is preferably designed as an inner drawer. This inner drawer can be arranged behind the front panel of the first pusher element, with the first pusher element being guided either under, above or next to the second pusher element via one or more pull-out guides.

The invention is explained in more detail below using several exemplary embodiments with reference to the accompanying drawings. Show it:

A piece of furniture 1 includes a furniture body 2, in which a first push element 3 is held movably via pull-out guides. The first thrust element 3 has a front panel 4 on one front, which protrudes upwards over the first thrust element 3 and, in the closed position, as shown in Figure 1, covers a second thrust element 5, which is arranged above the first thrust element 3. The first thrust element 3 is connected to the second thrust element 5 via a coupling mechanism with a flexible tension element 6.

In Figure 2, the first thrust element 3 has been moved into an opening position in front of the furniture body 2, so that the first thrust element 3 is accessible, but is not yet in the maximum opening position. The second push element 5 is still in the closed position, and a sliding guide 8 on the first push element 3, which is fixed to a railing 7, was moved along the flexible tension element 6. If the first push element 3 is now moved further in the opening direction, the sliding guide 8 pulls the flexible tension element 6 and thus the second push element 5 in the opening direction. Depending on the use of force, the second thrust element 5 can be moved at different speeds in the extension direction over the first thrust element 3.

3 shows the position of the furniture 1, in which both the first thrust element 3 and the second thrust element 5 are arranged in the maximum opening position. By opening the second push element 5, the sliding guide 8 has been moved again along the pulling element 6 and is now located in a rear area of the flexible pulling element 6. If the first pushing element 3 is now moved again in the closing direction, the sliding guide 8 pulls the flexible pulling element 6 and thus also the second thrust element 5 in the closing direction. Optionally, a movement of the second thrust element 5 can also take place via a stop or driver, with the movement of the second thrust element 5 being effected via the sliding guide 8 to avoid stop noises.

In Figures 4A and 4B, the sliding guide 8 on the first thrust element 3 is shown in detail. The sliding guide 8 is designed as a clamp or guide which is fixed to the railing 7 on a side wall of the first thrust element 3. For this purpose, a clamping device 9 is provided so that the sliding guide 8 is easily adjustable in the longitudinal direction of the railing 7 in order to be able to adjust the position when the first pushing element 5 is pulled in the opening direction or closing direction via the sliding guide 8. The flexible tension element 6, which is designed as a rope, is guided between the sliding guide 8 and the railing 7. Optionally, instead of a sliding surface, a roller or roller can also be provided on the sliding guide to reduce the frictional forces.

5 shows one of the two fixations 10 for fixing the flexible tension element 6 to the second push element 5. Each fixation 10 comprises a first part 11, which is fixed to a bottom of the second push element 5, and a second part 12, so that the flexible tension element 6 can be passed through between the two parts 11 and 12 and can be fixed there in a clamping manner. For this purpose, openings 13 are left in parts 11 and 12, into which fasteners can be screwed. The length of the flexible tension element 6 can be adjusted by the two fixations 10. In addition, the position of the fixation 10 can also be selected so that optimal handling of the coupling mechanism is guaranteed. The fixation 10 can also be made in one piece and fix the flexible tension element 6 directly against the second push element 5 in a clamping manner. 6 shows a modified piece of furniture 1' with a first pusher element 3' and a second pusher element 5', which are held movably in a furniture body (not shown). The first thrust element 3' has a front panel 4' which, viewed in the horizontal direction, covers the second thrust element 5'. A coupling mechanism is provided on a rear side of the two thrust elements 3' and 5', with a first connecting part 15 being fixed on the first thrust element 3' and a second connecting part 14 being fixed on the second thrust element 5'. The connecting parts 14 and 15 are each attached essentially centrally to a rear wall and connected to one another via a flexible tension element 16, for example a rope or band.

In Figure 7, the first push element 3 'is shown in an open position when the flexible tension element 16 is held tensioned between the first connecting part 15 and the second connecting part 14. In the tensioned position, the flexible tension element 16 is aligned essentially parallel to the extension direction of the first thrust element 3 'in order to avoid transverse forces when pulling out the second thrust element 5'. The second thrust element 5' can now be driven in the opening direction via the first thrust element 3 'via a pulling movement. If the second thrust element 5' is in the maximum opening position, the first thrust element 3' can now be used to also move the second thrust element 5' in the closing direction, whereby, unlike the first exemplary embodiment, the front panel 4' or another Driver moves the second thrust element 5 'in the closing direction. In this exemplary embodiment, the second connecting part 14 projects downwards over the second thrust element 5 'and the first connecting part 15 projects upwards over the first thrust element 3'. When the first pushing element 3' is moved in the closing direction, the first connecting part 15 comes into engagement with the second connecting part 14, whereby the second pushing element 5' is also moved in the closing direction. So that the engagement is dampened, the first and/or second connecting part can have a damping element 140, for example an elastomer. Alternatively, a separate driver, preferably damped, can also be arranged on the first thrust element 3 'or on the second thrust element 5', in particular in the area of the rear wall, so that the second thrust element 5' is taken along during a movement in the closing direction of the first thrust element 3' becomes. An example of a separate, height-adjustable driver 150 on the first thrust element 3 'is shown, for example, in Figure 8B. A damping element 140 can also be seen here on the second connecting part 14 engages with the driver 150. Additionally or alternatively, a damping element 140 can also be arranged on the first connecting part 15.

Figure 8A shows the two thrust elements 3' and 5' in the area of the rear walls. The second connecting part 14 protrudes downwards from the rear wall of the second push element 5 'and has a slot 17 in which the flexible tension element 16 is guided. The first connecting part 15 on the first push element 3 'also has a slot into which the flexible tension element 16 is inserted. The flexible tension element 16 can be designed so that it can be attached in a variable length. The user can thus decide from which extension path of the first push element 3 'the second push element 5' is taken along. If the flexible tension element 16 with a shorter length connects the two thrust elements 3 'and 5', the second thrust element is taken along earlier. The adjustability of the flexible tension element 16 can be achieved in that the tension element 16 is designed in such a way that balls or other shaped bodies are attached to the tension element 16 at a certain distance. The tension element 16 can be pushed onto the connecting parts 14 and 15 in the spaces between the balls. If the length is to be changed, the tension element 16 can simply be pulled out of the slot and pushed back in at a different distance.

Figure 9 shows the second connecting part 14 on the second thrust element 5 'in detail. The second connecting part 14 includes a mounting plate 18, which can be fixed to the rear wall of the second thrust element 5 'via fasteners. Several slots 21 and openings 22 for fasteners are left on the mounting plate 18. The second connecting part 14 further comprises a guide part 19, which is U-shaped and has projections 20 on both legs of the U, which can be inserted into the slots 21 on the mounting plate 18. The projections 20 can be inserted into different slots 21 to adjust the height of the guide part 19. In addition, openings 23 are left in the guide part 19 for fasteners. As a result, the guide part 19 can be fixed in different positions on the rear wall of the second thrust element 5 '.

In Figure 10, the first connecting part 15 for fixing to the rear wall of the first thrust element 3 'is shown in detail. The first connecting part 15 comprises a holder 24 which has a downwardly projecting web 25 which can be placed on an inside of the rear wall. A second fastening part 26 is angularly designed and can be inserted with a leg 28 under an angled wall of the rear wall on the first thrust element 3 '. A slot 27 for inserting the flexible tension element 16 is formed on the other leg. Other multi-part or one-piece connecting parts 14 or 15 can also be used to fix the flexible tension element 16 to the push elements 3 'or 5'.

11 shows a third exemplary embodiment of a piece of furniture 31 according to the invention, which has a furniture body 32 on which a first push element 33 with a plate-shaped front panel 34 is movably held. The front panel 34 projects laterally beyond the first thrust element 33 and, viewed in the horizontal direction, covers a further front panel 39 of a second thrust element 35. The thrust elements 33 and 35 are not arranged one below the other, but next to one another. In this exemplary embodiment, in the body on the left side, viewed from the front, there is a push element 33 with two drawers arranged one above the other, which are coupled to one another through the front panel 34. As can be seen in the open position in FIG. 12, each drawer is held movably in the furniture body 32 via pull-out guides 30. Likewise, on the right side, viewed from the front, there is a push element 35 with two drawers arranged one above the other, which are connected to one another by a front panel 39. In this exemplary embodiment, both thrust elements 33, 35 are approximately the same width. But it is also possible for one of the thrust elements 33, 35 to be wider than the other. The thrust elements 33, 35 are arranged in the body 32 in such a way that the front panel 39 corresponds approximately to the width of the thrust elements 35, whereas the width of the front panel 34 approximately corresponds to the body width. Such an arrangement of push elements 33, 35 in a furniture body 32 is particularly useful if the furniture 31 is positioned on a wall in such a way that the push element 33 is only easily accessible from the side on which the push element 35 is arranged in the furniture body 32 . The furniture body 32 can be designed as a base cabinet, upper cabinet or tall cabinet. Of course, the push elements 33, 35 can also be present in the mirrored arrangement in the furniture body 32 if the furniture 31 is arranged on a different disruptive edge.

In Figure 13 the thrust elements 33 and 35 are shown without the furniture body 32. The first push element 33 comprises two drawers arranged one above the other, which are connected to one another via the front panel 34. The Second push element 35 also includes two drawers, which are connected to one another via a further front panel 39. The push elements 33 and 35 can be opened in the manner of a pharmacy cabinet and then have one or more compartments one above the other, whereby more drawers or compartments can also be provided instead of the two drawers or compartments shown.

14 shows a top view of the two push elements 33 and 35 in a closed position, in which the front panel 34 covers an opening on the furniture body 32. In the rear area, a first connecting part 37 is fixed to the first pushing element 33 and a second connecting part 38 is fixed to the second pushing element 35, with a connecting part 37 or 38 preferably being fixed to each drawer of the pushing elements 33 and 35.

If the first push element 33 is moved in the opening direction by pulling on the front panel 34, a flexible tension element 36 is stretched between the first connecting part 37 and the second connecting part 38, as shown in FIG. 15. The second push element 35 is still in the closed position, and the flexible tension element 36 is stretched parallel to the extension direction. In this position, the user can now move the first thrust element 33 further in the opening direction and, by applying force, influence how quickly the second thrust element 35 is moved in the opening direction. In Figure 15 it can be clearly seen that good access to the push element 33 is possible from the right side in this case.

In Figure 16, the first thrust element 33 is shown in the maximum opening position, while the second thrust element 35 is arranged in a middle opening position. The flexible tension element 16 between the first connecting part 37 and the second connecting part 38 is no longer tensioned, but hangs downwards in a loop, which, however, is not visible to the user since this loop is arranged behind the first pushing element 33.

The second thrust element 35 can now be manually moved further in the opening direction until the second thrust element 35 is also arranged in the maximum opening position, as shown in Figure 17. The front panel 34 can be provided on the inside or the front panel 39 on the outside with an elastomer in order to stop the two front panels. dazzle 34, 39 together to dampen. Alternatively or additionally, anti-pinch devices can also be present.

In order to move the thrust elements 33 and 35 again in the closing direction, the first thrust element 33 on the front panel 34 is pressed in the closing direction, for example via a handle element (not shown), in which case the second thrust element 35 is then also moved in the closing direction, either via the contact through the front panel 34 against the front panel 39 and / or the stop of the two connecting parts 37 and 38 against each other.

In this exemplary embodiment in particular, it is advisable to pretension the flexible tension element 36 by at least one energy accumulator, in particular by means of a roller spring, which in the inserted position winds the flexible tension element 36 on a body, for example a drum, from which it is supported during the movement of the The first thrust element can be unwound until it reaches the tensioned position. This makes it possible to avoid the flexible tension element 36, in the loop-shaped state, getting caught on another component if there is a narrow space due to the installation space. This storage, in particular rope storage, can be set up on both the first and second furniture part.

The above exemplary embodiments can be combined with one another as desired. For example, the connecting parts 37 and 38 can be provided with adjustment options in order to change the arrangement and orientation of the flexible tension element 36. In addition, the length of the flexible tension element 36 can be adjusted.

The solution described is particularly suitable for a piece of furniture with an inner drawer with inner panels made of glass or with a glossy look, since the inner panel is not visually affected by a conventional glued or mechanical driver, nor are fingerprints left on the glass when the inner drawer is opened or closed .

Even if the first pusher element cannot be opened completely without the second pusher element being moved in the opening direction, the full contents of the first pusher element are still accessible to the user, since the contents can be accessed diagonally from the front via the front panel. The user can still reach up to the back wall of the first push element, even if the last cm is always from the second push element can be covered if this is arranged above the first thrust element.
