Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device having a guide unit for guiding a movable furniture draw-

The present invention relates to a device according to the preamble of claim 1 and to furniture furnished with such a device.

Pull-out guides for drawable households, especially drawers, shelves, etc., are known, including devices for synchronizing the guides. In this case, for example, a wheel or roller which can be rolled in the section of the guide rail for synchronization is used. The synchronization is provided in a so-called full draw-out, in particular comprising a main rail, a drawer rail and an intermediate rail acting therebetween. In particular, a guide rail is used which is used as an underfloor guide or as a side guide in a special position relating to the assembly or structural features. These guides are constantly in need of special solutions that have not always been completely satisfactory.

An object of the present invention is to improve the synchronization of the draw-out guide with a full draw-out for use as an underfloor guide or side guide.

This object is achieved by the claims 1, 3, 13 and 14. The dependent claims follow a preferred refinement of the invention.

The present invention is based on a device comprising a guide unit for guiding a movable furniture drawer with respect to the main body, in particular with a guide unit arranged in a sidewall area below the base or the furniture drawer, the guide unit comprising a main rail A drawer rail which is mountable on the furniture drawer, and a middle rail which acts between the main rail and the drawer rail, the guide unit comprising a first bearing means for transmitting a load between the intermediate rail and the main rail, And a second bearing means for transferring a load between the rails, wherein each of the bearing means comprises a body and rolling means accommodated in contact with the body or housed in the body for supporting the rails movably relative to each other And there is a synchronization means for synchronization of the guide unit. A first important concept of the invention is that the synchronization means comprise one or more synchronization members which interact with the body of each bearing means.

It is particularly preferred if the synchronizing member penetrates at least one groove of the intermediate rail and interacts with the body of each bearing means at each side of the groove.

Thus, this is particularly preferably possible, in particular, in an underfloor guide which improves the synchronization of the guide unit with respect to the compact structure or the reliability of synchronization. In this case, the present invention takes advantage of the knowledge that it may be sufficient to synchronize the guide units by synchronizing the bodies of the respective bearing means with each other. This is because the synchronized movement of the main rails, the intermediate rails and the drawer rails can also be achieved by synchronizing the bodies of the respective bearing means, which is ultimately the object of the synchronizing device. Synchronization of guide units can be implemented economically or technically preferably by means of the presented device. This is because synchronization of the guide through the body of the bearing means may be preferable to other synchronization solutions for technical reasons. One reason may be that the body between adjacent rails movable relative to each other is arranged to save space in a relatively narrow intermediate region. Thus, in the full draw-out with the first bearing means between the main rail and the middle rail and the second bearing means between the middle rail and the draw-out rail, on both sides of the intermediate rail, which is usually only made of sheet metal, A state in which the main body of the bearing means and the main body of the second bearing means are arranged very close to each other or only in a state in which they are separated from each other only by the thin plate thickness and the narrow gap width of the intermediate rail can be used. Synchronization of the guide through the synchronization of the bearing means, preferably with the groove and the synchronization member located in this groove, can be implemented.

In the known underfloor guide portion, the roller conveying portion between the main rail and the intermediate rail and the roller conveying portion between the intermediate rail and the drawing rail are usually arranged in a space such that there is no direct free space between these roller conveying portions. In particular, these roller carriers can be separated from each other through wall portions of the guide rails or through their cohesive arrangement with respect to each other. Synchronization between the roller carriers is heretofore only implemented by complicating the structure in the side guides. No corresponding solution in the underfloor guide has been known.

It is also not necessary to have a flat free section for rolling the synchronizing member in the body rail and the draw-out rail for the presented device, since it is usually necessary for the rails to have a plurality of structures such as for example a stop, a bend, It is likewise preferred because it comprises the member or molded member to be distributed over its length, and such a plurality of members prevent the synchronization member from rolling over the required rolling length.

The synchronization of the guide portion or the synchronization of the bearing means can be preferably solved by the structure according to the invention, particularly in the underfloor guide portion or the side guide portion. As a bearing means for transferring the load, for example, parts which are slidably arranged to be movable between adjacent rails, for example a body or a slide, may be used, which may include, for example, rolling means such as a rolling contact body And is rotatably supported and accommodated. For example, they can be roller conveyors made of plastic, which in particular can accommodate the rolling means in different ways and, in some cases, can also be received interchangeably. For example, there may be a rolling or rolling contact member, for example one or more rollers, wheels or similar parts, in the carrying part. In most cases, the plurality of rolling members are oriented differently in the conveying portion. One conveyor or a plurality of conveyors may be provided between two adjacent rails.

On the basis of the present invention, the synchronization of the guide unit also includes the case where the synchronization of the guide unit is performed only by the synchronization of the bearing means, for example. However, a plurality of synchronization means or other further synchronization means may also be provided for the synchronization of the guide unit basically, for example including means for implementing synchronization directly between the rails.

A further important concept of the invention includes that the synchronization means comprise one or more synchronization members that can be releasably installed in the section of the intermediate rail. Therefore, in a simple assembling step, the synchronizing member may be mounted on or separated from the guide portion in some cases in the future.

It is preferable that the synchronizing member is formed as a rolling member which is rolled in a relative section of the two bodies when the furniture drawer moves. Thus, for example, the assisted synchronization of the bearing means-body by means of a wheel or roller having elasticity or ductility can be structurally simple. This also results in a solution with a particularly low wear and / or noise. The synchronizing member or the rolling member is rotatably received in the intermediate rail except for a possible bearing clearance with a set position, i.e. not slidably self-fixed to the intermediate rail.

It is also advantageous when the synchronizing member is formed as a toothed wheel that is rolled in the serrated sections of the two bodies as the furniture drawer moves. In this way, the slip of the intermediate rail relative to the body of the bearing means can be prevented. This is because the toothed wheel is engaged with the two toothed sections through the toothed wheel and the toothed portion in the toothed section, that is to say at the top of the toothed wheel-toothed shaft for example the toothed portion of the toothed wheel, Section and is coupled with the serration section of the bearing means body between the intermediate rail and the main rail at the bottom of the toothed wheel-rotation axis. However, if the toothed wheel device, preferably with serrated sections, is structurally or technically more complex than the other rolling members, or only to a lesser extent, it can be operated with a significantly higher reliability than these.

It is further proposed that the synchronization member is rotatably received about a horizontal or vertical axis with the device mounted. The linear sliding movement of the draw-out portion can preferably be synchronized, at least by a horizontal or near-vertical axis, that is, when a small angular deviation can be taken into account or is sometimes required. This is because when the device is mounted, it is usually necessary to implement a horizontal movement or a horizontal movement outwardly of the furniture draw-out portion so that the synchronization member can rotate about a horizontal axis or a vertical axis. Also, assembly can be simplified accordingly.

It is also preferred that the synchronization member is rotatably received about an inclined axis with the device mounted. This may be desirable, for example, for structural reasons, for example where the synchronization member interacts with a section of the beveled state of the body of each bearing means, in particular with a section inclined relative to the vertical or space axis . ≪ / RTI >

It is also advantageous that the synchronizing member is received in a holding part which can be interchangeably mounted on the intermediate rail. Thereby, the synchronization member can be firmly supported or protected and placed in a separate part. Such a holding part may also be better matched to the structural preset part and mounted to the intermediate rail, i.e. it may be fixed, for example, separated from the groove, which may facilitate fixed mounting. Otherwise, the synchronization member will always have to be fixed in the adjacent area of the groove of the intermediate rail, which may be a disadvantage in relation to the strength of the intermediate rail already weakened here by the groove. It is also very difficult to manually mount on the intermediate rail, but when the locking member is housed in a relatively larger holding portion and the holding portion is dimensionally designed to be mountable or detachable by hand or using a tool, A relatively small synchronization member may be used that is well fitted.

In addition, it is preferable that the synchronizing member is supported by the holding portion while being vertically spaced while the device is mounted. For example, the synchronization member may include a cylindrical center hole for receiving through a suitable bearing shafting device within the holding portion. The bearing shaft device of the holding part can be formed such that the shaft section inserted into the cylindrical hole is not particularly precisely cylindrical but rather flat so that the synchronizing member has a clearance in one direction, And has a vertical clearance when the drawer portion is mounted on the main body so as to be usable. By virtue of this vertical clearance, a gap, preferably occurring in relation to the position of the serration section height or in particular in relation to the position of the serration section relative to the intermediate rail or the synchronization member, can be accommodated or compensated.

Also, with a vertical clearance, a sort of minimum clearance with the horizontal orientation of the received synchronization member can not be completely blocked, but is not a problem. Preferably, the vertical clearance is greater than the horizontal clearance. In a fixed configuration, this vertical clearance may be, for example, from about 0.2 mm to 0.4 mm, while the horizontal clearance may be, for example, 0.02 mm.

It is also desirable that a fixing means for mounting the holding part to the intermediate rail in the correct position is provided. The securing means can be formed in different types, and in particular can be made particularly clickable so that the holding part can be removably mounted on the intermediate rail. To this end, in particular, the forming part may be formed in the holding part, for example, a protrusion or recess or groove formed integrally with the holding part may be provided, which can interact with the relative section of the intermediate rail, . In particular, the securing means can additionally be used to precisely align or precisely align the mounting position to secure the holding portion to the intermediate rail.

It is also preferable that the fixing means of the holding part in the state in which the device is mounted acts on the wall section of the intermediate rail located laterally with respect to the wall section through which the synchronization member penetrates. As such, a particularly compact device of synchronization means can be implemented. In this way, the intermediate rail can also be matched to the mounting portion of the holding portion better in terms of rigidity, and in particular, it is possible to generate a lower stress in the holding portion or to apply stress relatively compensated, .

Basically, this holding part may additionally or singly be positioned so as to act on the wall section through which the synchronization member penetrates. The fitting or fixing of the holding part to the intermediate rail suitably can be determined or adjusted, for example, by means of a corresponding mechanical operation.

It is particularly preferred that fixing means for implementing the at least one two-point fixture in the intermediate rail are formed. Particularly preferably, a fixing means for realizing the three-point fixing portion on the intermediate rail is formed. Thus, the holding portion can be sufficiently rigidly mounted to securely accommodate the forces and torques that occur when the device is actuated.

According to a further important concept of the invention there is a synchronization means for the synchronization of the first bearing means and the second bearing means and for the synchronization of the main rail, the intermediate rail and the draw-out rail. In this way, particularly reliable and reliable synchronization of the guide unit can be achieved. In addition to the synchronization of the bearing means body, additionally or concurrently synchronization is effected via corresponding synchronizing members of the three drawer rails. In this case, a synchronization member for the synchronization of the three rails on the one hand and the synchronization of the two bearing means on the other hand can be formed through the same type of synchronization member or similarly different synchronization members. For example, the pinion may be mounted on the intermediate rail and rolled in the section of the main rail and the output rail, or the pinion may act between the opposite friction wheel and each of the bearing means bodies so that the pinion engages sections of the main rail and the draw- The friction wheel is rolled in the section of the body.

The invention also relates to a furniture comprising one of the above-mentioned devices and having a furniture drawer movable relative to the main body. Thus, the above-described advantages for furniture, especially for furniture with drawers or drawers, are implemented.

In the drawings, the same reference numerals are used for corresponding members in different embodiments.

Fig. 2 is a sectional view of the furniture 1 with the drawer 3 (furniture drawer) slidably housed in the main body 2 and a cutout Are shown. In order to slidably guide the drawer 3 to the main body 2, the guide unit 4 is provided as a full draw-out type of an underfloor type. On the side of the furniture 1 which can not be shown in cross-section, the drawer 3 is accommodated so as to be slidably movable in an additional main body section through a further corresponding guide unit. The guide unit 4 includes a main rail 5, a drawer rail 7 (drawer rail) slidable thereto and a movable intermediate rail 6 acting between the main rail 5 and the drawer rail 7 do. A mounting jaw 5a having an opening for mounting to the side wall 2a of the main body 2 through suitable fastening means (not shown) is a part of the main rail 5. Further, the main body 2 includes the base 2b or includes the rear wall 2c at the rear. The drawer 3 has a front panel 3a, a side surface 3b, a rear wall 3c, and a base 3d. On the bottom side of the base 3d, the drawer rail 7 is fixed through fixing means not shown in more detail. In particular, the unillustrated portion of the furniture 1 comprises an additional sidewall 2a of the main body 2 or an additional side 3b of the drawer 3.

A pinion 8 (synchronizing member) rotatably received in the holding part 9 is provided for synchronizing the bearing means (described in more detail below) present in the guide unit 4. [ 2 is shown in order to clearly show the apparatus having the pinion 8 or the holding part 9 inside the guide unit 4. [ Thus, the pinion 8 is fixed to the intermediate rail by the holding portion 9. However, basically, the pinion 8 may be directly rotatably received in the intermediate rail. The pinion 8 is received in a holding portion 9 used as a pinion holding device and the holding portion 9 can be detachably mounted on the intermediate rail 6. [ The pinion 8 engages with the rack 10 of the upper roller carrying portion 12 at the same time when the guide unit 4 is fully assembled with the holding portion 9 installed and at the same time the lower roller carrying portion 13). ≪ / RTI > The relative movement between the intermediate rail 6 and the drawer rail 7 is possible since the upper roller carrying portion 12 acts between the drawer rail 7 and the intermediate rail 6 in bearing form. To this end, a plurality of rolling bodies or rolling contact bodies which transmit loads in the form of, for example, rollers, balls or wheels, may be rotatably received in the upper roller conveying part 12. [ The lower roller conveying part 13 is used as a bearing between the intermediate rail 6 and the main rail 5 and the upper and lower roller conveying parts 12 and 13 are arranged so that when the drawer 3 is slid It is self-moving.

When the drawer 3 is pulled out or pushed against the main body 2 in the mounting state shown in Figs. 1, 2, 5 and 6, when the pinion 8 engaged with the racks 10 and 11 rotates In order to achieve synchronization of the two upper and lower roller conveying parts 12 and 13, the upper or lower roller conveying part 12 or 13, according to the invention, comprises a rack 10 or rack 11 integrally formed here .

The provision of the pinion 8 or the holding portion 9 on the intermediate rail 6 is explained in more detail by FIGS. 3A to 4C. A pinion 8 is rotatably supported on the holding portion 9 and is aligned and positioned in the receiving portion 14 of the holding portion 9. The pinion 8 and the holding portion 9 are particularly preferably made of plastic. An invisible stub shaft for accommodating the pinion 8 is formed in the region of the receiving portion 14 and the stub shaft is fixed to the pinion 8 when the pinion 8 or the holding portion 9 is assembled, Or may be curved so as to be somewhat resilient and fall off from each other to fit the pinion 8 into the holding portion 9. [ The stub shaft in the receiving portion 14 is not particularly accurately formed in a cylindrical shape, whereas a cylindrical hole exists in the center of the pinion 8. Since one side of the stub shafts is slightly flattened, the pinion 8 includes a slight upward and downward clearance in accordance with the double arrow P1 of FIG. 3B in the mounted state. Due to this clearance, a clearance for the position of the racks 10 and 11, which may occur as occasion demands, can be accommodated.

The intermediate rail 6 shows a slotted groove 15 into which the pinion 8 and the receiving portion 14 of the holding portion are inserted when the holding portion 9 is fitted. 3A and 4A, the pinion 8 and the holding portion 9 in the apparatus shown are so arranged that the toothed portion or section of each of the three teeth of the pinion 8 is located above the upper surface 6a of the intermediate rail And is fitted to the intermediate rail 6 so as to protrude. These teeth protrude above the upper surface 6a through the groove 15 until the pinion 8 can securely engage the upper rack 10. [ On the opposite side, the pinion 8 is correspondingly engaged with the lower rack 11.

The holding portion 9 is formed as a flat part extending in the longitudinal direction and a clip 16 having two clip jaws 16a and 16b which are resilient and slightly compressible with respect to each other is supported by the end portion 9 of the holding portion 9 Lt; / RTI > A clip 16 is used to detachably mount the holding portion 9 at the correspondingly mounted position of the intermediate rail 6. [ To this end, an insertion opening 17 is formed to latchably insert the clip jaws 16a and 16b into the intermediate rail 6. The insertion opening 17 is here provided in the wall portion of the intermediate rail 6 arranged at a right angle to the upper surface 6a. The insertion opening 17 and the clip 16 are latched in the insertion opening 17 with the clip jaws 16a and 16b in a state in which the holding portion 9 is inserted into the intermediate rail 6 according to Figures 3a and 4a To match each other. Since the two clip jaws 16a and 16b are only slightly compressed in order to separate the holding part 9 from the intermediate rail 6, the relevant end of the holding part 9 can be separated from the intermediate rail. A nose portion 18 is present in the holding portion 9 for fixing or fixing the holding portion 9 to the intermediate rail 6 in a fixed manner. The nose portion is a middle portion when the holding portion 9 is fitted, Is inserted into the opening (19) in the rail (6). A flat tongue 20 is also provided at the end of the holding portion 9 lying opposite the clip 16, in order to position the holding portion 9 in the correct position on the intermediate rail 6. [ When the holding part 9 is fitted to the intermediate rail, the tongue 20 is pushed down to the stop position beneath the lug 21 protruding from the intermediate rail 6 while being bent.

The rim section of the collar-shaped receiving portion 14 and the groove 15 can likewise be matched to each other to assist in fixing the holding portion 9 to the correct position on the intermediate rail.

Figure 6 shows the upper roller carrying part 12 and the lower roller carrying part 12 by the pinion 8 having the holding part 9 according to the embodiment corresponding to Figures 1 to 5 for the synchronization of the guide unit 4. [ 13, there is shown a further embodiment of a device according to the invention in which not only synchronization means are provided but also synchronization means in the form of rollers 22 are formed between the rails 5, 6 and 7. The roller 22 is present on the intermediate rail 6 so as to be rotatable about a horizontal axis with the guide portion mounted. When the drawer 3 is pulled out, the roller 22 is rolled in the sections of the main rail 5 and the drawer rail 7 with the synchronization by the pinion 8, so that the main rail 5, the middle rail 6, And the drawer rail 7 are realized.

Basically, the roller and pinion with corresponding relative sections in the apparatus according to Fig. 6 may be exchanged with each other, or only two pinions or only two rollers may be used for synchronization in the intermediate rail 6.

Furthermore, it is contemplated that a plurality of pinions or a plurality of rollers may be used in the guide unit, such as, for example, one or more additional pinions according to FIG. 6 and / or one or more additional rollers.

The embodiment shown in Figure 7 comprises a pinion 12 which is rotatably supported on the intermediate rail 6 and meshed with the tooth profile 12a of the upper roller carrying portion 12 and the tooth profile 13a of the lower roller carrying portion 13, (8). The upper roller conveying part 12 is provided with three bearing bodies 23 or rolling contact bodies in the form of rollers of the upper roller conveying part 12 or two bearing bodies 23 Is rotatably accommodated about a vertical rotary shaft or a horizontal rotary shaft when the guide unit is mounted in an available state, for example. The bearing body 23 is in bearing contact with the sections of the main rail 5 and the middle rail 6 or with the sections of the drawer rail 7 and the intermediate rail 6. In the embodiment shown in accordance with FIG. 7, the synchronization of the guide unit 4 is achieved only by synchronizing the upper and lower roller conveying parts 12 and 13 by the pinion 8.
