Description

Austrian Patent Office AT 11 009 U1 2010-03-15

Description: The invention relates to a device according to the preamble of claim 1 and to a piece of furniture with such a device.

STATE OF THE ART

To support a closing operation with a retraction in a defined end position of a movable furniture part, which is movably mounted on a furniture body, various arrangements are known. For example, can be used for this purpose, a retracting or closing automatic for pulling, tilting or pivoting furniture parts. For example, guide devices for drawers or extracts are provided with a so-called automatic retraction, which also often has a damping device for damping or deceleration of the retraction movements. As movable furniture parts come in addition to drawers, for example, extracts, rotary, swivel or sliding doors or front doors in question.

OBJECT AND ADVANTAGES OF THE INVENTION

Object of the present invention is to provide a device of the type described or a piece of furniture, whereby the ease of use of a piece of furniture, which is provided with such a device is improved.

This object is solved by the claims 1 and 12. In the subclaims advantageous embodiments of the subject invention are shown.

The invention is first of a device for drawing a relative to a furniture body via a guide unit movable furniture part, wherein the guide unit has a carcass rail on the furniture body and a displaceable to the carcass rail pull-out on the movable furniture part comprising a force storage device for providing a pulling force to retract the movable furniture part in a closed position on the furniture body, a damper for damping the retraction movement of the movable furniture part and a slider which is movable back and forth under the action of the force accumulator and the damper and with a releasable coupling between the furniture body and the movable furniture part is possible, wherein in the coupled state by moving out of the movable furniture part from the closed position of the power storage is rechargeable. An essential aspect of the invention is that transmission means are provided, through which in the mounted state of the device a force to be applied for moving the movable furniture part from the closed position to an open position is less than that provided by the energy storage device on the slider in the drawing direction of the movable furniture part Force. Advantageously, so that the force required to move out or opening the movable furniture part, despite effective Einziehmechanik be comparatively low, compared to the force provided by the power storage force for pulling the movable furniture part. This can take into account the fact that in almost all cases, a comparatively high force for retracting the movable furniture part should be effective to safely and completely move, for example, movable furniture parts with larger dimensions or high weight or higher loads , Relatively high loads can occur, for example, in drawers or drawers in the kitchen area, for example when they are filled with a plurality of heavy kitchen utensils or dishes, for example in a stacked arrangement. On the other hand, the applied force when opening the movable furniture part should be comparatively small or only as large as absolutely necessary, especially if the opening is done by a person or essentially only by muscle power.

In previous systems with Einziehunterstützung it is disadvantageous that to open the movable furniture part from the closed position, the necessary force is spent to a not insignificant proportion for the acting counterforce of the energy storage to 1/14 Austrian Patent Office AT 11 009 U1 2010 -03-15 overcome. So far, this share of force when opening in the order of magnitude of the force acting in the pull-in force when retracted by the energy storage force. In most cases, the force component to be applied for this is almost the same as the force with which the energy accumulator pulls it in the direction in which the movable furniture part is pulled in. By contrast, the transfer means according to the invention can now be used in particular from outside e.g. be applied by a person applied force to open or remove the furniture part significantly. In this way, a relatively heavily loaded furniture part or a drawer or a particularly difficult to move furniture part without further opening. As a result, even weaker, elderly or disabled persons or children with a correspondingly lower force can open the movable furniture part, even if a strong pull-in device is present.

Preferably, the transmission means are designed such that with the movement of the movable furniture part in an open position simultaneously acting on the slider in the drawing-in direction of the movable furniture part force of the force accumulator acts. In this way it can be ensured that within a defined first part of a pull-out from the closed position, at any time the movable furniture part can be brought in the open position just achieved with the desired comparatively high pull-in force by the energy storage in a closed position. In this way, it can be avoided that a partially open or slightly open movable furniture part remains in a slightly extended position, which, for example, a resulting risk of injury, e.g. can be excluded for children.

So far, a compromise with regard to the effective forces between modes with different objectives was always necessary in known systems. Either the power provided by the power storage was lower to choose so that you could still open the movable furniture part comparatively easy or it was a relatively large pull-in force provided by the energy storage to safely move, for example, even heavily loaded extracts, but it is difficult or uncomfortable and with increased effort was possible to open the drawer or the drawer. In individual cases now drawers or extracts of a person, for example, a child or a disabled person can be opened, which could not be opened by these people without arrangement according to the invention. In addition, automatic retraction systems can now be used for furniture in which it was previously not possible to provide an automatic retraction mechanism from the mentioned disadvantages when opening.

Preferably, the transmission means are designed so that the charging of the energy storage takes place by moving out of the movable furniture part from the closed position. In this way, an ideal combination of the use according to the use of the movable furniture part with the activation of the energy storage can be achieved. After the closing operation, the energy accumulator is usually in an uncharged or a comparatively weakly charged state, for example a tension element or tension element which is not stretched or only slightly tensioned. In principle, the energy storage device must be brought from this state before the next Einziehvorgang back into a charged state. Ideally, the charging of the energy accumulator can be linked to the movement of the movable furniture part when pulling out.

In principle, the opening can be done except by muscle power alone, alternatively completely motor or by combination of muscle and motor power. As a result, a corresponding charge of the energy accumulator is conceivable, for example, motor assisted. However, this is relatively complex and expensive compared to the charging of the energy storage by moving out of the movable furniture part from the closed position by hand or by muscle power.

It is further proposed that the transmission means are designed such that the force to be applied for moving the movable furniture part from the closed position to an open position is approximately half as large as the force memory on the slider ready 2/14 Austrian Patent Office AT 11 009 U1 2010-03-15 adjusted opposing traction. In this way, the necessary force to pull out or move the movable furniture part from the closed position on a particularly easy for a person still reach level, which makes it possible for almost every person to open the movable furniture part or from the closed position bring to. In addition, can be compared to the opening high forces to implement the moving furniture part.

In an advantageous embodiment of the subject invention, two rolling profiles are provided, on which a slider fixed rotatable rolling element abrol-len can len. With such an arrangement, the slider can be moved in a mechanically simple manner and to save space.

It is particularly advantageous if the rolling profiles comprise a roll-off profile fixedly attached to the pull-in device and a roll-off profile which is displaceable relative to the pull-in device. Thus, with simple means and small footprint, the movement of the slider can be realized. In particular, forces can be transmitted safely between the slider and the rolling profiles.

Preferably, the rolling element comprises a pinion, which can roll in two opposing tooth profiles. With the comparatively simple mechanical components of a pinion or two opposing tooth profiles, the overall arrangement can be easily or even inexpensively produced. In particular, larger forces can be transmitted between the pinion and the counter-tooth profile in both directions of rotation of the pinion, in particular without fear of undesired slippage or uneven rolling of the interlocking components.

It is also preferred that a coupling element is configured, by means of which the withdrawal movement of the movable furniture part with the movement of the slider can be coupled. This makes it possible, at least temporarily, a coupling of the movable furniture part or the associated pull-out rail with the slider or the coupling can be canceled again. The coupling or decoupling can in particular be automated or automatic, e.g. depending on the current position of the moving furniture part. Basically, for example, a movable arrangement of the coupling element and / or a cooperating with this counterpart is conceivable. In particular, when the movable furniture part is pulled out of the closed position, a corresponding coupling can take place on a first section of the opening movement path of the movable furniture part or a decoupling on reaching the end of the first section. The decoupling is done in particular when the energy storage is again loaded or stretched to meet the desired power storage function at the next retraction of the movable furniture part can.

Preferably, the coupling element is pivotally articulated to the sliding Abrollprofil. With this arrangement, the slider can be moved via the coupling element on the rolling profile and the rolling element cooperating therewith. In particular, a reduction ratio can be realized by which the force for charging the energy store is about half as large as the force of the force accumulator acting on the slider. In this case, the movable furniture part and thus the coupling element is moved with the sliding Abrollprofil in a time unit by twice the distance, as the slider with the rolling element in the same direction. In this way, the force ratios according to the invention are realized with the reduction.

It is further proposed that a pivotable ausgestaltetes catch element is provided, with which a coupling between the slider and the movable furniture part takes place when pulling the movable furniture part. When retracting or moving, the movable furniture part or, e.g. the pull-out rail connected to the slide in the direction of the closed position under particular full force of the energy storage is realized when pulling the coupling between the slider or the furniture body and the movable furniture part or attached thereto arrangement via a catch element which is articulated on the slider. As a rule, the pull-in movement is effected via the force accumulator acting directly or indirectly on the slide, in particular.

The invention also relates to a piece of furniture, in particular with a drawer slidably received in a furniture carcass by means of a carcass rail and a pull-out rail, and optionally a center rail, as a movable furniture part, which has one of the above-mentioned devices. In this way, the advantages listed for the appropriately equipped furniture can be realized.

FIG. 1 shows a guide unit 1 with a carcass rail 2, a pull-out rail 3 and a pull-in automatic system 4, wherein the pull-out rail 3 is slidably received in relation to the carcass rail 2 according to the arrows P1 and P2. The guide unit 1 can be used, for example, for movably guiding a drawer (not shown) as a movable furniture part on a furniture carcass, wherein a guide unit is present on both sides of the drawer. To realize a full extension may optionally be additionally provided a displaceable between the carcass rail 2 and the pull-3 3 middle rail.

The carcass rail 2 comprises an attachment section 2a, in which in two subregions 5 round openings for fixed attachment, for example on a carcass wall, are formed. At an approximately perpendicular to the attachment portion 2a angled leg portion 2b of the rail 2. (see also Figure 10), the automatic retraction 4 is attached, for example, clipped or screwed. The Ausziehschiene 3 is not shown arrangements, such as a roller carriage with bearing bodies on the carcass rail 2 movable, ie. slidably guided and limited by cooperating stops on the rails 2, 3 in the path of movement. The carcass rail 2 and the pull-out rail 3 are in particular made of bent sheet metal material, wherein the pull-out rail 3 in cross section is substantially U-shaped with folded-over edges (see FIG. 10).

For a better representation of the automatic retraction 4, the pull-out rail 3 is omitted in Figure 2, which is shown in Figure 1 in a fully retracted position relative to the carcass rail 2. The automatic retraction 4 has a damper 6, e.g. a fluid damper, and a Öffnungskraftreduktion 7. The individual parts of the automatic retraction 4 are shown in particular in Figures 3 to 7. Accordingly, the fluid damper 6 comprises a damping cylinder 8, in which a Dämpffluid housed and in which a piston with a piston rod 9 arranged thereon is longitudinally displaceably movable. The automatic retraction 4 has a holding plate 10, which in particular can be detachably fastened to the carcass rail 2. Attached to the front end of the piston rod 9 or an end piece 9a located thereon is a displacement piece 11 which is coupled and reciprocally movable with the piston rod 9 and guided relative to the holding plate 10. On the sliding piece 11 engages to apply a pulling force when closing, e.g. a drawer to a tension element, for example, a coil spring 12 which is guided around an obliquely to the leg portion 2b aligned deflecting wheel 13 in the rear region of the automatic retraction 4 fitting. The coil spring 12 is in each case fixed to the end of the holding plate 10 and the sliding piece 11. In Figures 3 to 6, the piston rod 9 is shown with the sliding piece 11 in the extended position, which results in a pull-in stand-by position when e.g. a drawer attached to the pull-out rail 3 is in an open position. In this case, the spring 12 is tensioned with the application of a bias on the sliding piece 11. On the sliding piece 11, a pinion 14 is also rotatably received. The pinion 14 engages with its teeth in two oppositely formed parallel tooth profiles, which are precisely matched to the teeth of the pinion 14 for a suitable mesh. One of the tooth profiles is formed by a tooth profile rod 15 movable in the longitudinal direction of the automatic retraction 4. Opposite, a further toothed profile 17, which is designed to be stationary on a housing section 16 of the automatic retraction mechanism 4, is provided. The tooth profiles 16 and 17 are approximately the same length and are formed or positioned such that the pinion 14 in the tooth profiles 16, 17 can roll over the entire in both directions according to P1 and P2 considered displacement distance of the sliding piece 11 engaging. In Figure 4, the housing portion 16 is omitted with the tooth profile 17 for better representation of the sliding piece 11.

At the toothed profile bar 15, a coupling lever 18 is pivotally attached via a pivot point 19. When opening e.g. a drawer or when moving the pull-out rail 3 from the position e.g. According to FIG. 1 or 9 in the direction P1, the toothed profile bar 15 and thus the displacement piece 11 are coupled with the movement of the pull-out rail 3 with the aid of the coupling lever 18. Here comes on the pull-out rail 3 (see Figure 9) projecting Ausziehmitnehmer 20 in contact with the coupling lever 18 and is moved with this in the direction of arrow P1. With the pull-out movement, the toothed profile bar 15 also moves in the direction of P1 and via the cooperation with the pinion 14 and the sliding piece 11 is moved at half withdrawal speed in the direction P1. By realized with the pinion 14 and the tooth profiles 15, 17 reduction the sliding piece per unit time is only moved by half the distance in the direction P1, as the pull-out rail 3 and the associated toothed profile bar 15. Thus, only half the force on the coupling lever 18 necessary to move this together with the tooth profile rod 15 in the direction of P1, whereby a Öffnungskraftreduktion example is provided for the drawer to be opened. The length or the position in particular of the toothed profile bar 15 with respect to the pinion 14 is chosen so that the pull-out rail 3 over a part of its displacement path or the Öffnungswe- one of them arranged furniture part brings the energy storage or the spring 12 in its desired bias position. The biasing position may coincide with a spring tension which provides a spring force which can be safely and completely drawn into a closing position of the pull-out rail 3 or the e.g. arranged drawer is necessary.

Has the sliding piece 11 reaches the position shown in Figure 3 to 6 by the pull-out of the pull-3, the Ausziehmitnehmer 20 comes out of contact with the coupling lever 18, because this pivots about the pivot point 19 slightly backwards in the direction of the mounting portion 2a, so that the Ausziehmitnehmer 20 is released from the coupling lever 18 and can move past it in the direction P1. The pull-out rail 3 or a drawer correspondingly arranged thereon can thus be brought into a further open position, the pull-out rail 3 being decoupled from the pull-in automatic mechanism 4. So that the sliding piece 11 is held in the extended position as described achieved under biased spring 12, the coupling lever 18 is guided via a trained thereon underside guide pin 18a by means of a guide 21 in the housing portion 16 and held in the extended position of the sliding piece 11 in a locking position , The guide 21 is, as is clear in particular from FIG. 9, designed substantially in the direction of the pull-out direction of the pull-out rail 3 as, for example, a straight link guide and bent in its end section lying in the pull-out direction P1, so that in this end position the coupling lever 18 moves around the pivot point 19 can fold behind and under the spring force of the spring 12 and the sliding piece 11 is fixed in the position thus reached.

In this locking position, the toothed profile bar 15 is in the position according to FIGS. 3 to 6.

If, in a closing operation, e.g. moves the drawer with the puller 3 in the direction of P2 (see Figure 1 and Figure 9), a Einziehmitnehmer 22 (see Figure 9) on the puller 3 in abutment against the sliding piece 11. The Einziehmitnehmer 22 is the Ausziehmitnehmer 20 in the direction P1 or slightly spaced in the direction of withdrawal. For the interaction of the Einziehmitnehmer 22 with the sliding piece 11, a catch element 23 is pivotally mounted on the underside of the sliding piece 11 and guided via a slotted guide 24 in the holding plate 10 in the retraction or extension movement of the pull-3. The slide guide 24 can be seen in particular in the figure 6, 7. Here, at the bottom of the catch element 23, a guide pin 25 engaging in the slotted guide 24 is formed. The Einziehvorgang or the interaction of the pull-3 with the automatic retraction 4 will be explained in more detail below.

Starting from the position shown in Figures 3 to 6, the catch element 23 is according to the gate 24 in a zurückgeschwenkten position, which is defined by a curved end portion of the slotted guide 24, wherein the guide pin 25 is retracted in this curved end portion (see FIG. 6). By the effective direction of the tensile force generated by the spring 12 on the sliding piece 11, the guide pin 25 can not escape from the bent end portion of the slotted guide 24 and the sliding piece 11 is locked in the corresponding pull-out position. In addition, the sliding piece is as described above on the locked tooth profile rod 15 also blocked in the extended position, whereby a kind of double-locking the locking of the sliding piece 11 is realized. If the pull-out rail 3 is now moved in the closing direction P2, the pull-out driver 20 first moves past the pivoted-on coupling lever 18 until the pull-in driver 22, which is formed somewhat vertically spaced from the coupling lever 18, abuts against a catch nose 23a on the catch element 23, thereby moving the pull-out rail further 3, the catch element 23 is pivoted forward in accordance with the slide guide 24 so that the pull-in driver 22 is carried along by a further catch nose 23b of the catch element 23. With the abutment of the Einziehmitnehmers 22 at the first catch nose 23a and the coupling lever 18 is released from its locking position in the guide 21 and pivoted forward, so that a retraction movement of the displacement element 11 in the direction P2 under the effect of ange¬ 6/14 Austrian Patent Office AT 11 009 U1 2010-03-15 tensioned spring 12 can take place. When retracting the pull-3, the catch nose 23b is applied to Einziehmitnehmer 22 and brings this with the pull-3 in the direction P2. This retraction movement is also damped by the retraction movement of the piston rod 9 of the fluid damper 6. The pull-3 is therefore brought damped under the force of the spring 21 in a retracted position. In the fully retracted position of the pull-out rail 3 or the drawer positioned thereon, the automatic retraction 4 with damping and opening force reduction 7 is in the position according to FIG. 1 or FIG. 7. In principle, the slide guide 24 can be designed such that the end of the Pulling the catch element 23 back into a zurückschwwenkte position shown in Figure 3 to Figure 6 and not as shown in Figure 7 remains in the retraction position and until the subsequent retraction of the sliding piece 11 at the end of the slide guide 24 pivots backwards.

As a result of the described reduction, the coupling lever 18 overtakes, during its displacement movement, the catch element 23, which likewise moves, in the respective direction P1 or P2.

A further embodiment of an automatic retraction mechanism 26 is explained in more detail with reference to FIGS. 11 to 15b, which is comparable in basic construction to the retractable automatic mechanism 4 according to FIGS. 1 to 10. FIGS. 11 and 12 show a rear area of the automatic retraction mechanism 26 with a retaining plate 27, on which a spring 28 is guided around a deflection wheel 29 adjacent. In FIGS. 11 and 13, the spring 28 is not shown for better illustration of the automatic retraction mechanism 26.

Figure 11 and Figure 12 show a detail of the arrangement in which the spring 28 is less tensioned or a force acting on the spring 28 sliding piece is retracted. The figures 13 and 14, however, show the stronger tensioned spring 28 with extended and latched sliding piece (not shown).

The rotatably mounted guide wheel 29 is provided with a sliding seat and attached here to a slidably received on the support plate 27 sliding plate 30. The sliding plate 30 is designed as an angled sheet metal element (see Figures 15a and 15b), with a shorter leg 30b (see Figure 15a) to which a pin 31 is attached, and a longer leg 30a, in which the guide wheel 29 is received. To realize a sprung sliding seat a spiral spring 32 is fitted encompassingly on the sliding plate 30 on the pin 31, which is plugged with its other end portion on a further pin 33 which is fixed in position on the retaining plate 27 is present.

The sliding plate 30 is reciprocally guided on the holding plate 27 by means of a provided on an underside of the holding plate 27 oblong hole 34 and forth. When comparatively more tensioned spring 28, when the sliding piece, not shown, is kept extended, by the wrap of the spring 28 on the outer circumference of the guide wheel 29, the slide plate 30, starting from the position shown in Figures 11 and 12 in the according to the figures 13 and 14 shown position along the slot 34 in the direction of the arrow P1 (see Figure 12) against the spring force of the coil spring 32 urged. This can be done cushioned, which is gentle on components and low noise.

In less tensioned spring 28 and retracted sliding piece is in interaction with the coil spring 32 through this pushed the sliding plate 30 in the direction of the arrow P2 (see Figure 14), wherein the sliding plate 30 with a section not shown in detail in the slot 34 may abut against an end wall of the elongated hole 34 or is slightly spaced therefrom. The displacement distance of the deflecting wheel 29 in the slot 34 can correspond to a maximum of one distance a (see FIGS. 12 and 13), for example, amount to a few millimeters up to more than 10 millimeters.

With the spring-guided movable receptacle of the sliding plate 30 and thus of the deflecting wheel 29, jerky or short-term force or voltage changes of the prestressed spring 28 can be picked up by the sliding plate 30 via the deflecting wheel 29 7/14 Austrian Patent Office AT 11 009 U1 2010-03-15 men. In particular, mechanically occurring load peaks on components of the automatic retraction mechanism 26 are damped or attenuated.

Optionally, this can also be an undesirable noise, especially during a Einziehbewegung, a movable with the automatic retraction 26 furniture part or, for. avoid a drawer or at least significantly reduce it.
