Description

The present invention relates to a pull-out guide for a furniture part that can be moved relative to a furniture body, in particular for a drawer, with a body rail to be connected to the furniture body, a drawer rail movably mounted on the body rail, which can be connected to the movable furniture part and has a longitudinal axis, wherein the drawer rail is movable along the longitudinal axis in the opening and closing direction of the movable furniture part, a drive device for moving the drawer rail and the movable furniture part connectable thereto at least in a partial area of the movement path between a closed position and an open position and a depth adjustment device for adjusting the closed position of the drawer rail relatively to the body rail, wherein the depth adjustment device has a carrier, a stop element movable relative to the carrier along the longitudinal axis and a depth adjustment wheel rotatably mounted on the carrier about an axis of rotation for moving the stop element along the longitudinal axis. In addition, the present invention relates to a piece of furniture with a furniture body, a movable furniture part and such a pull-out guide.

When it comes to pull-out runners and furniture in general, it is important that when installed, the individual components have as uniform a design as possible and are arranged regularly. Above all, the furniture fronts should create a uniform appearance. This means that all furniture fronts of drawers arranged next to one another or one above the other should be in the respective one Closed position lie in the same (vertical) plane. In order to be able to accomplish this on furniture with built-in pull-out guides, so-called depth adjustment devices are provided, with which the relative position between the body rail and the drawer rail (in the horizontal direction) given in the closed position can be changed and adjusted.

The AT 512 748 B1 shows an adjusting device for adjusting a position of a drawer relative to a drawer pull-out guide with a stop that can be moved by an adjusting wheel to rest on the drawer pull-out guide. This means that it is not the relative position between the drawer rail and the cabinet rail that is set in the closed position, but rather the relative position of the drawer to the drawer rail. No ejection device is described. In addition, the adjustment wheel rotates about an axis of rotation which is aligned transversely to the longitudinal axis of the shutter rail.

A very similar device comes from the EP 2 661 194 B1 in this prior art, the adjusting wheel can be rotated about an axis of rotation which is aligned parallel to the longitudinal axis of the drawer rail.

In contrast, an example of a piece of furniture with a depth adjustment option for adjusting the relative position between the drawer rail and the cabinet rail is shown in the DE 10 2016 120 586 A1 out. The ejection device described has a force-applied drive element. The position of this drive element relative to a driver can be adjusted using a knurled nut can be adjusted to adjust the closing position of the movable furniture part. In the furniture fitting described, the ejection device including the drive element and knurled nut is either completely fixed to the furniture body or fixed to the movable furniture part. An example is shown with ejectors attached to the bottom of the drawer on both sides. The disadvantage of the variant fixed to the furniture body is, among other things, that the knurled nut in the depth of the furniture body is very difficult or difficult to reach by hand. The disadvantage of the variant fixed to the furniture body is, among other things, that the ejection device takes up a relatively large amount of space on the drawer and that the entire furniture fitting (pull-out guide including ejection device) therefore has to be relatively wide.

In a very similar way, the ejection device according to EP 2 654 507 B1 educated. In order to be able to adjust the gap between the front panel and the furniture body, an adjustment mechanism for the ejection stop is provided on the carriage, which has an adjustment path. By turning the nut, the ejection stop can be moved in the closing or opening direction. The adjustment of the panel gap can be carried out either with the thrust element open or closed, with better access to the nut on the underside of the drawer when the thrust element is open. Here too, the disadvantage is that the entire furniture fitting takes up a lot of space and is relatively wide.

A similar embodiment variant is shown in the DE 20 2015 104 436 U1 shown embodiment, in which the ejector unit and the adjustment arrangement attached to this ejector unit are attached to the underside of a drawer. Only in the description is a variant mentioned, according to which the device can also be attached to guide means of the furniture part and/or to the furniture body. Regarding the adjustment arrangement, it is also stated that this can be designed independently of other elements, such as an ejector or a trigger of the energy accumulator of the device on the furniture and/or on the movable furniture part and/or on guide means of the furniture part. It is not stated that the adjustment arrangement is designed or arranged independently of the entire ejector unit.

The EP 1 996 046 B1 shows a device for influencing the movement of furniture parts that can move towards one another. Adjustment means are provided for adjusting the position of a positioning element on the movement rail, on which a pull-pressure element acts to apply the drive effect to the furniture part. The adjusting element is fixed to an attachment element, this attachment element in turn being attached to the drawer rail. In contrast, the displacement rod of the pull-compression element is attached to the base rail part (corresponds to the body rail) via a guide profile. The adjusting element is therefore assigned to the drawer rail, while the pull-push element including the displacement rod (corresponds to the ejection device) is assigned to the body rail. What is complicated with this state of the art is that the sliding rod must be fixed to the adjusting element. This is done, for example, by a fixing screw screwed onto an end face of the pin which prevents the sliding rod from being pulled out of the adjusting ring. The pin can also be pressed, welded, glued, squeezed, pinned or similar in the insertion opening. This means that the sliding rod must always follow the entire movement path of the drawer rail relative to the base rail part (carcase rail). As a result, the displacement rod has to be very long, which is relatively complex and complicated. Another disadvantage of this state of the art is that the adjustment element is difficult to access. In particular, adjustment can only be made using a suitable tool (e.g. a screwdriver with a Phillips head).

The object of the present invention is to create an alternative pull-out guide to the known prior art. In particular, the disadvantages of the prior art should be eliminated or avoided as far as possible.

This is solved by a pull-out guide with the features of claim 1.

In the pull-out guide according to the invention it is provided that the axis of rotation of the depth adjustment wheel is aligned parallel to the longitudinal axis. This allows the depth adjustment wheel to be operated in a simple manner.

Furthermore, according to the invention it is provided that the drive device is mounted on the body rail. As a result, the drive device can remain assigned to the furniture body and does not have to be moved with the movable furniture part when opening and closing According to the invention it is also provided that the carrier of the depth adjustment device is mounted on the drawer rail. This means that the depth adjustment device can be easily accessed. The depth adjustment device can be easily and quickly reached by hand, especially when the movable furniture part is open. The depth adjustment device is therefore not “hidden” somewhere inaccessible in the depths of the furniture body.

In addition, it is provided according to the invention that the stop element rests against a stop counterpart of the drive device in the closed position and can be detached from the stop counterpart during the movement path from the closed position to an open position. The stop element therefore does not have to be in constant contact with the stop counterpart. The stop element does not have to follow the entire opening and closing path of the shutter rail. In other words, the stop element is detachably connected to the stop counterpart. Specifically, this configuration ensures that the stop element is spaced from the stop counterpart of the drive device once a certain open position has been reached. The stop element therefore only moves with the stop counterpart over a partial area of the opening and closing path.

Preferred embodiments of the present invention are defined in more detail in the dependent claims.

For a simple design of the depth adjustment device, it is provided that the stop element has a driver and has a motion transmission area connected to the depth adjustment wheel.

The driver can be designed as a simple, flat stop surface. However, it is preferably provided that the driver is bolt-shaped.

It is preferably provided that the bolt-shaped driver extends at right angles to the longitudinal axis and - when installed in the furniture body - in the vertical direction.

In order to enable movement conversion, it is preferably provided that the movement transmission area is designed as an external thread wound around the axis of rotation.

According to a preferred exemplary embodiment, it is provided that the depth adjustment wheel is at least partially sleeve-shaped around the axis of rotation.

It is particularly preferably provided that the depth adjustment wheel has an internal thread wound around the axis of rotation, this internal thread corresponding to the external thread of the motion transmission area.

Furthermore, it is preferably provided that the internal thread is formed on an inner surface of the depth adjustment wheel which occupies an angle of a maximum of 180 ° about the axis of rotation and that the depth adjustment wheel has a recess in that area which is radially opposite the said inner surface. Expressed differently The depth adjustment wheel has an exemption (recess or opening) in the area radially opposite the internal thread. This exemption ensures that the depth adjustment wheel and its thread do not have to be laboriously turned out during production in an injection molding tool. This makes demoulding the depth adjustment wheel much easier.

It is particularly preferably provided that the depth adjustment wheel has an actuation area which is formed by the lateral surface of the depth adjustment wheel formed around the axis of rotation. This actuation area is therefore not formed on an end face of the depth adjustment wheel, but on its lateral surface. This means that the depth adjustment wheel can be turned and operated manually without tools.

According to a preferred exemplary embodiment, it is provided that the depth adjustment wheel has a knurl on its outside, preferably on its lateral surface, preferably aligned along the longitudinal axis. This makes it easier to grip and operate the depth adjustment wheel with your fingers.

It is preferably provided that the depth adjustment device has a latching knob and latching recesses corresponding to the latching knob, preferably arranged at regular intervals around the longitudinal axis. This can create a “rattling” feeling when actuated. The operator can therefore better estimate how far the depth adjustment wheel has already been turned. Each snap into another snap recess corresponds to one further change in depth by a certain distance (e.g. 0.1 mm to 0.5 mm).

In order to prevent the stop element from rotating when the depth adjustment wheel is rotated, it is provided that the depth adjustment device has an anti-rotation mechanism for the stop element in the carrier.

The drive device can be designed as a retraction device for retracting the movable furniture part from an open position into a closed position.

Preferably, the pull-in device can have a carrier attached to the body rail, a pull-in slide that is movable relative to the carrier, and a pull-in force accumulator connected to the carrier and the pull-in slide.

The retraction device can also have a damper to dampen the retraction movement, ensuring gentle and smooth closing.

As an alternative (or in addition) to the ejection device, it can be provided that the drive device is designed as an ejection device for ejecting the drawer rail from the closed position into an open position.

It is preferably provided that the ejection device has a carrier attached to the body rail, an ejection carriage that is movable relative to the carrier and an ejection force accumulator connected to the carrier and the ejection carriage.

It is also preferably provided that the ejection device has a locking device for locking the ejection carriage in a locking position. By over-pressing the movable furniture part into an over-pressing position behind the closed position, the locking device is unlocked and the ejection force store ejects the ejection carriage together with the movable furniture part in the opening direction. The locking device can have a heart-shaped locking track and a locking pin that can be moved in this locking track. However, other locking variants are also possible, for example in the form of the ballpoint pen principle.

Furthermore, it is preferably provided that in the closed position the ejection carriage of the ejection device rests on the stop element of the depth adjustment device via the stop counterpart formed on the ejection carriage. If the ejection carriage is in the closed position at a certain relative position to the drawer rail (and thus to the furniture body), the relative position of the drawer rail to the cabinet rail can be changed by adjusting the stop element along the longitudinal axis. This in turn causes the depth position of the movable furniture part and its front panel to be adjusted relative to the furniture body and can be adjusted accordingly.

In order to ensure safe movement of the driver with the ejection carriage both in the opening direction and in the closing direction, it is preferably provided that the ejection carriage has a stop counterpart has co-forming catch lever, which in the closed position engages around the driver of the stop element and holds it in a form-fitting manner. When a certain open position is reached (e.g. after an opening distance of approx. 30 mm to 120 mm), the detachable connection between the catch lever and the driver is released again.

Protection is also provided for a piece of furniture with a furniture body, a movable furniture part and a pull-out guide according to the invention.

Particularly preferably, it is provided that the movable furniture part is movably mounted on the furniture body via two pull-out guides mounted on opposite sides of the furniture body and preferably designed mirror-symmetrically to one another.

In Fig. 1 In general, a piece of furniture 8 is shown with a furniture body 3 and a total of four movable furniture parts 2 in the form of drawers. Each drawer consists of at least one drawer 10 and a front panel 11. The drawers have a (drawer) pull-out guide 1, consisting of a drawer rail 5 and a body rail 4 (and possibly a middle rail, not shown) attached to the furniture body 3.

A drive device 6 is shown schematically in the top drawer. The drive device 6 has a carrier 62. In this case, this carrier 62 is attached to the drawer rail 5. According to the invention, the drive device 6 is - in contrast to Fig. 1 - attached to the body rail 4. In this case, the drive device 6 is designed as an ejection device 61, with the ejection carriage 63 and the ejection force accumulator 65 of this ejection device 6 being shown schematically. The locking device 66 has a guide track 67 formed in the carrier 62 and the locking pin 68 guided in the (in this case heart-shaped) guide track 67. A driver 74 is arranged on the body rail 4 (or on the furniture body 3 itself), with which the ejection device 61 engages at least in sections. According to the invention, the arrangement is reversed: That is, the drive device 6 is assigned to the body rail 4, while the driver 74 is assigned to the movable furniture part 2. This top drawer is in the open position OS.

When the drawer is moved from this open position OS in the closing direction SR, the locking pin 68 moves in a closing section of the guide track 67. The ejection force accumulator 65 is tensioned by a relative movement between the ejection carriage 63 and the carrier 62.

In the closed position SS (third drawer from the top), the ejection force accumulator 65 is fully tensioned. This closed position SS can be achieved by a purely manual closing movement. Alternatively, the drawer - if present - can be moved or retracted into the closed position SS by the retraction device 69, which is only shown schematically and is integrated into the pull-out guide 1.

Starting from this closed position SS, the drawer moves into the push-over position ÜS (bottom drawer in.) by pressing on the drawer Fig. 1 ). This results in the unlocking of the locking device 66. After the overpressing carried out in the closing direction SR - as soon as the user no longer presses on the drawer - the drawer is ejected by the drive device 6 in the opening direction OR. This brings the drawer into the open position OS according to the second drawer from above. In this position the drawer can e.g. B. can be gripped over the front panel 11 and moved further by hand into the position according to the first drawer from above.

In Fig. 2 A drawer (movable furniture part 2) with a drawer 10 and a front panel 11 is shown in perspective. In addition, an arrangement of two pull-out guides 1, each with two drawer rails 5 and two body rails 4, is shown, with one drawer rail 5 and one body rail 4 of the pull-out guide 1 being provided on both sides of the drawer. Further shows Fig. 2 a drive device 6. The drive device 6 is attached to the body rail 4.

This drive device 6 (or its carrier 62) extends in the closing direction SR of the drawer. This closing direction also corresponds to the longitudinal axis L of the drawer rail 5 or the entire pull-out guide 1. Especially in the case of smaller or narrower drawers 2, it is sufficient if only one drive device 6 is assigned to the drawer. This can (as shown) be assigned to the right-hand pull-out guide 1 (but also to the left-hand pull-out guide 1).

In Fig. 3 A movable furniture part 2 including drawer rail 5 and body rail 4 is shown in perspective. The circle shown shows the depth adjustment device 7, which is mounted on the drawer rail 5.

Fig. 4 shows that in Fig. 3 Detail shown in a circle in an enlarged form. The essential components of the depth adjustment device 7 can therefore be seen. This depth adjustment device 7 is composed of the carrier 71, the stop element 72 and the depth adjustment wheel 73. The carrier 71 is firmly connected to the drawer rail 5. The stop element 72 is mounted in the carrier so as to be displaceable along the longitudinal axis L. The depth adjustment wheel 73 can in turn be rotated about the axis of rotation D. As can be seen, the axis of rotation D and the longitudinal axis L are aligned parallel to one another.

In the Fig. 5 to 10 the movable furniture part 2 with the pull-out guide 1 is shown from above and in the closed position SS, with the differently adjusted depth adjustment device 7 generating a different dimension for the front panel gap F. Generally in the said Fig. 5 to 10 the movable furniture part 2 is partially hidden, so that a view in the direction of the depth adjustment device 7 and the drive device 6 is given.

In Fig. 5 and in detail Fig. 6 It can be seen that the stop element 72 is extended relatively far relative to the carrier 71. Since the stop element 72 rests on the stop counterpart 60 (not visible in detail here) of the drive device, there is a relatively large front panel gap F.

If the depth adjustment device 7 is actuated via the depth adjustment wheel 73, the stop element 72 is moved linearly relative to the carrier 71. In Fig. 7 and the associated detail 8, this results in a smaller front panel gap F in the closed position SS.

If the depth adjustment wheel 73 is turned further in the same direction, a position as in will soon result Fig. 9 and according to the associated detail Fig. 10 . The stop element 72 is almost completely retracted into the carrier 71. A front panel gap F is practically no longer present.

From a comparison of the Fig. 5 , 7 and 9 It also results that in the closed position SS there is a different relative position between the body rail 4 and the drawer rail 5.

In Fig. 11 and according to the associated detail Fig. 12 the pull-out guide 1 is shown in perspective. The Drive device 6 is located between the drawer rail 5 and the body rail 4. As a result, the furniture fitting is relatively narrow overall. The furniture fitting is therefore limited laterally by the two rails 4 and 5, the drive device 6 does not protrude laterally.

In Fig. 13 and according to the associated detail Fig. 14 the pull-out guide 1 is shown as a (vertical) section. It can be seen that the body rail 4 and the drawer rail 4 are each designed as curved metal profiles. The drawer rail 5 is movably mounted on the body rail 4 via rollers 9. In Fig. 14 Above all, the carrier 71 and its attachment to the drawer rail 5 as well as the stop element 72 can be seen.

The Fig. 15 to 18 show in perspective and in detail a further embodiment variant of the pull-out guide 1. This embodiment variant differs from the previous one in the design of the drive device 6. In this case, the drive device 6 is designed as a pull-in device 69, whereas in Fig. 11 the drive device 6 is designed as an ejection device 61.

It can also be provided that the drive device 6 combines both functions and functions both as an ejection device 61 and as a retraction device 69.

In Fig. 15 the pull-out guide 1 is in the closed position SS, whereas in Fig. 17 the pull-out guide is shown in an open position OS. In the closed position SS, the stop element 72 lies on the stop counterpart 60 of the drive device 6. On the other hand, is in Fig. 17 the stop element 72 is spaced from the stop counterpart 60 and thus released.

Said stop counterpart 60 can be formed on a catch lever. In the closed position SS, the catch lever engages around the driver 74 of the stop element 72 and holds it in a form-fitting manner. When moving in the opening direction OR, the positive connection is canceled by pivoting the catch lever.

In the Fig. 15 to 18 the so-called drawer rail 12 is shown in each case. This serves as a connecting device for connecting the drawer container 10 to the drawer rail 5.

The Fig. 19 to 38 show a first exemplary embodiment of a depth adjustment device 7 in different representations, perspectives, (partial) sections and details.

In Fig. 19 the components of the depth adjustment device 7 can be seen in an exploded view.

The carrier 71 is designed as a, preferably metallic, curved bracket. This carrier 71 has a base region 711 and two holding tabs 712, which protrude essentially at right angles from the base region 711, each with guide openings 713 formed therein. In addition, an opening 714 for the locking element 7c is formed in the carrier 71.

The stop element 72 is mounted in the guide openings 713 so as to be displaceable along the longitudinal axis L. The stop element 72 has a bolt-shaped driver 74 and a movement transmission area 75. The movement transmission area 75 is designed as an external thread 76 wound around the axis of rotation D.

Between the driver 74 and this external thread 76, the stop element 72 has lateral projections 721. These projections 721, together with corresponding recesses in the area of the guide opening 713, form an anti-rotation mechanism for the stop element 72 in the carrier 71, so that the stop element 72 does not turn over the axis of rotation D can rotate.

The depth adjustment wheel 73 is at least partially sleeve-shaped around the axis of rotation D and has an elongated opening with an internal thread 77 wound around the axis of rotation D. This internal thread 77 corresponds to the external thread 76 of the motion transmission area 75 of the stop element 72. On its outside - in particular on its lateral surface - the depth adjustment wheel has a knurl 79. This knurling 79 is lamellar or rib-shaped, with the lamellar or ribs extending along the longitudinal axis L.

Locking recesses 7b are formed on the depth adjustment wheel 73 (these correspond to the “slat valleys”). These locking recesses 7b correspond to the locking knob 7a of the locking element 7c. When turning the depth adjustment wheel 73, a “ratcheting feeling” is created via this latching knob 7a. In addition, the depth adjustment wheel is 72 held in its position by the locking element 7c, so that it cannot rotate around the stop element 72 when vibrations occur and would thereby undesirably adjust the depth position or the front panel gap F.

In Fig. 20 The depth adjustment device is shown in an assembled state. The stop element 72 is guided through the two guide openings 713 and the depth adjustment wheel 73 is rotatably mounted on the stop element 72, with movement of the depth adjustment wheel 73 along the longitudinal axis L being prevented by the retaining tabs 712 of the carrier 71.

Fig. 21 shows again the same representation as Fig. 20 .

In Fig. 22 a better view of the depth adjustment wheel 73 is given. It can be seen that the depth adjustment wheel 73 has a recess 78. This is advantageous for the production of the depth adjustment wheel 73 and its internal thread 77 in a plastic injection molding process.

Fig. 23 shows a view through this recess 78 of the depth adjustment wheel 23, with a small part of the internal thread 77 and a larger area of the external thread 76 being visible. The knurling 79 on the lateral surface of the depth adjustment wheel 23 is also clearly visible.

The detail according to Fig. 23 comes from the perspective view of the depth adjustment device 7 from Fig. 24 .

The Fig. 25 and 26 show the depth adjustment device 7 cut off in the middle from different perspectives.

In Fig. 27 It can be seen that the stop element 72 is flattened on one side in the area of the external thread 76. This makes the rotation of the depth adjustment wheel 73 on the external thread 76 smoother because there is less friction.

Fig. 28 shows a to Fig. 29 relevant detail of the depth adjustment device 7.

In the Fig. 30 to 34 the depth adjustment wheel 73 is shown in different perspectives. In the front view according to Fig. 32 It can be seen that the thread elevations of the internal thread 77 stand out from the remaining inner surface of the depth adjustment wheel 73 in the direction of the axis of rotation D. This enables a relatively smooth rotational movement. In the 33 and 34 It can be seen that the internal thread 77 is not formed on the full circumference, but only on half the circumference of the inner surface of the depth adjustment wheel 73. The recess 78 is located radially opposite this internal thread 77.

In Fig. 35 a section through the depth adjustment device 7 is shown, which is shown in Fig. 36 is shown. The internal thread 77 as well as the corresponding external thread 76 are clearly visible. The locking element 7c with its locking knob 7a, the bolt-shaped driver 74 and the carrier 71 can also be seen.

By rotating the adjusting wheel 73 about the axis of rotation D, the depth adjusting device 7 reaches the position according to 37 and 38 .

Fig. 39 shows a further exemplary embodiment of a depth adjustment device 7. The stop element 72 including the driver 74 and movement transmission area 75 is designed practically identically to the previous exemplary embodiment. There are differences in the depth adjustment wheel 73, which has fewer lamellar knurls 79. However, this depth adjustment wheel 73 has more, specifically three, recesses 78.

In Fig. 40 is the depth adjustment device 7 according to Fig. 39 shown in assembled condition.

In the Fig. 41 to 43 the depth adjustment wheel 73 is shown in different perspectives. In Fig. 41 the recesses 78 are clearly visible.

Fig. 42 shows a top view of a half-cut depth adjustment wheel 73. This provides a clear view of the three separate internal threads 77, which are each arranged radially opposite a recess 78.

On average according to Fig. 43 In this case, the locking knob 7a formed directly on the depth adjustment wheel 73 can be seen.

The in Fig. 44 marked cut is in Fig. 45 shown. The three half-shell-shaped internal threads 77 are each opposite the recesses 78 arranged and correspond to the external thread 76 of the stop element 72.

The Fig. 46 to 49 show a third exemplary embodiment of the depth adjustment device 7. In contrast to the previous exemplary embodiments, an expanding element 722 is arranged at the end of the stop element 72 remote from the driver. This prevents the stop element 72 from being able to be completely unscrewed from the carrier 71 and the depth adjustment wheel 73.

In Fig. 48 the different design of the locking element 7c can be seen. According to the details Fig. 49 the locking knob 7a is held between the lamellar knurls 79 on the lateral surface of the depth adjustment wheel 73.
