Description

The present invention relates to a pullout guide, with a fixable guide rail and a movably mounted track, between which a middle rail is optionally arranged, wherein at least one latching device is provided for releasably fixing the track to the guide rail and the latching device comprises a spring element and an engagement element.

From the WO 2010/060724 a pull-out guide is known in which one or more spring elements are provided as latching means. The spring elements act together with a profiling or recess on the rail. Although these spring elements can provide a locking function, but lie in the inside or in the inner region of the pullout guide when it is in a collapsed position. As a result, they are difficult to access. In addition, the spring elements are designed as filigree components due to the limited space, which can be damaged in continuous operation.

It is therefore an object of the present invention to provide a pullout guide, which comprises an easily accessible latching device to lock the running rail on the guide rail in at least one position.

This object is achieved with a pullout guide with the features of claim 1.

According to the invention, the at least one latching device of the drawer guide with the spring element and the engagement element is arranged on an outer side of the drawer guide in the moved-together position. As a result, the spring element and the engagement element are easily accessible from the outside and can be easily mounted and replaced in case of damage, provided that the connection point is reversible. In addition, larger components can be mounted on the outside, which are also suitable for continuous operation.

According to the invention, the spring element is bendable and the engagement element is dimensionally stable. The spring element can, for example, bent as a V-shaped Be formed strip. Also, a training as a vertical web, which is pivoted outwards or inwards, is possible.

In one embodiment, the at least one latching device is arranged on an inner side in relation to the installed position of the pullout guide. A drawer slide is usually installed in a furniture carcass or a household appliance and therefore fixed to a side wall, a side rail or fasteners. The sidewall facing side of the pullout guide forms the outside, while the interior facing side, which is directed to a drawer or a food support, forms the inside. The mounting of the locking device on the inside leads to the advantage that the accessibility is given even in the installed position.

Furthermore, the spring element is bendable by the engagement element in a direction perpendicular to the direction of movement of the track rail. In this case, the spring element can be bent inwards or outwards in order to achieve a latching. The latching can act only in one direction, so complicate movement of the running rail in one direction, or act on both sides to prevent movement of the running rail at a certain locking position or over a certain locking area addition.

For the formation of a latching device with few components, the engagement element is formed integrally with the running rail or the guide rail. For this purpose, the engagement element may be formed, for example, as a V-shaped web. This leads to the advantage that the cogging forces can be adjusted by adjusting the angle of inclination of the legs of the V-shaped web. Likewise over the height or the passage depth of the V-shaped web, the detent forces can be varied.

According to one embodiment, a middle rail is provided, which is accommodated in the retracted position in an inner space between the guide rail and the running rail. The guide rail and the running rail are formed by angular or U-shaped profiles which form a cavity between them, so that the middle rail is arranged protected.

For example, the spring element and / or the engagement element are at least partially coated with a lubricant. This can be for the permanent use of the locking device a smooth locking be guaranteed. Suitable lubricants are lubricant compositions with an organic silicon compound, boron nitride, graphite, silicone oil or other lubricants.

Alternatively, the spring element and / or the engagement element can be provided with a sliding element of a heat-resistant material with good sliding properties, for example of PEEK or LCP.

The spring element and / or the engagement element are fixed to the running rail or the guide rail non-positively, positively or materially, preferably welded, and thus fixed inextricably. There are also other joining methods for fixing the spring element and / or the engagement element conceivable, for example, screws, rivets or clips. The attachment points for fixing the spring element and / or the engagement element can also be generated by laser welding.

In the pullout guide two locking positions can be provided, a detent position in a closed position and a detent position in an extended position of the pullout guide. For this purpose, two spring elements can interact with one engagement element or two engagement elements with a spring element.

On the entire travel of the pullout guide arbitrarily defined locking positions can be generated by the interaction of spring elements and / or engagement elements according to the invention.

According to a further embodiment, the spring element is fixed to the running rail and protrudes in the longitudinal direction of the running rail over the running rail. As a result, the drawer guide can be designed as an overdraw, in which the running rail is arranged in a fully extended position in the longitudinal direction spaced from the guide rail. About the protruding spring element can still take place a locking in the open position. Alternatively, the spring element can also be arranged in the region of the running rail.

In a further embodiment, the spring element is formed as an angular plate with a bendable spring bar and a holding portion, wherein the holding portion is fixed to the running rail or the guide rail. In this case, the holding portion may extend in the longitudinal direction of the guide rail or the running rail and be fixed only in the region on the side facing away from the bendable spring bar part on the guide rail or the running rail. This makes it possible to realize a particularly smooth locking, since the spring element can bend not only in the region of the bendable spring bar, but at least partially also in the region of the holding section. By shifting the fixing position (for example welding position) on the elongated spring part in the longitudinal direction, the spring rate can thus be increased or reduced.

In order to increase the holding forces in a latched position, preferably at least two locking devices are provided to lock the running rail in a predetermined position on the guide rail, for example in an extended pull-out position. The locking devices can be arranged on opposite sides of the running rail and / or the guide rail. This leads to the advantage that when locking no or only very small torsional forces act on the running rail, so that a rotation of the rail is largely avoided. This reduces wear and increases smooth running when moving the running rail. The locking devices can be set both with their spring elements both on the running rail or the guide rail, but also a determination each only one spring element on the running rail and a spring element on the guide rail is possible.

In one embodiment, the spring elements of the two locking devices are arranged offset in the longitudinal direction of the running rail, but are latched substantially simultaneously. By these offset spring elements designed the installation width of the pullout guide is substantially reduced and requires little space.

The pull-out guide according to the invention is preferably used in a household appliance, such as an oven, wherein at least one pullout guide is arranged on opposite sides of the baking oven muffle.

A pullout guide 1 comprises a movably mounted running rail 2 and a fixable stationary guide rail 4, between which a cavity is formed, in which a middle rail 3 is arranged, which is arranged largely concealed in a contracted position. On the guide rail 4, a front bracket 5 and a rear bracket 6 are fixed in the lower region, which are fixed to a side rail for an oven. The pullout guide 1 can also be used for other household appliances or furniture, so that instead of the brackets 5 and 6 other fastening means for fixing the guide rail 4 are used.

On the running rail 2, a plate-shaped stopper 7 is fixed to the front, while the rear side an upwardly projecting pin 8 is arranged. By over the running rail 2 upwardly projecting plate 7 and the pin 8 food support or other components can be positioned defined on the running rail 2.

To move the pullout guide in the collapsed position ( FIG. 1 ) and in an extended opening position ( FIG. 5 ) releasably fix each, locking devices are provided. A first latching device comprises a spring element 10, which is fixed with a flat web 11 on the guide rail 4, for example by welding or gluing. The spring element 10 comprises a v-shaped or U-shaped protruding from the running rail 4 bendable portion 12 which cooperates with an engagement member 20. The engagement member 20 is formed as a metallic plate which is fixed with a flat vertical portion on the running rail 2. The engagement member 20 includes an outwardly projecting step 21, projecting from the two downwardly directed pins 22, between which the arcuate portion 12 of the spring element 10 can be inserted. In the latched position (Figure 2), the running rail 2 is releasably fixed on the spring element 10 via the engagement element 20, wherein the spring element 10 must be pressed in a direction perpendicular to the direction of movement of the running rail 2 to the guide rail 4 both in the opening direction and in the closing direction to release the engagement member 20.

The running rail 2 can then be moved after unlocking in an open position, in which case the middle rail 3 between the running rail 2 and the guide rail 4 is visible. In an opening position, the engagement element 20 engages with the downwardly directed pins 22 on a second spring element 30, which is fixed to a front region of the guide rail 4. The spring element 30 comprises a strip-shaped section 31, which is fixed to the guide rail 4 in a force, form or material fit, for example by welding or gluing, and a bent inwardly projecting portion 32. The arcuate portion 32, as in the spring element 10 between the two pins 22 are moved for the latched position. In the spring member 30, a stop 33 protruding inward from the guide rail 4 is further formed, which prevents the engagement member 20 from being moved beyond the opening position. As a result, the running rail 2 can be moved out of the latched opening position only in the closing direction. Such a stop 33 can also be provided in the spring element 10, so that stops on the guide rail 4, the middle rail 3 and the running rail 2 can be omitted. By manual depression of the spring element 30, the stop can be overcome to pull out the pullout guide, if desired, even further.

In the description of the following embodiments, the same reference numerals as in the FIGS. 1 to 6 used for identical or functionally identical components.

In the in the FIGS. 7 and 8th As shown embodiment, a pullout guide 1 is shown, in which on the running rail 2 and the guide rail 4, a central portion is not shown, so that the rolling elements 15 are visible, which are held on a Wälzkörperkäfig. The running rail 2, the center rail 3 and the guide rail 4 are each mounted on rolling elements 15 movable relative to each other. In the retracted state, the Wälzkörperkäfige with the rolling elements 15 are far away from the locking position and may require to compensate for radial movement tolerances a different locking height than in the extended detent position.

At the in FIG. 7 and 8th Shown embodiments are also provided latching devices on the outside of the pullout guide 1, wherein the latching device comprises a spring element 40 which is fixed to the running rail 2 and comprises a bendable vertical web 41, the engagement elements 50 is latched. The engagement elements are formed by V-shaped curved webs which protrude on the inside of the guide rail 4. In this case, an engagement member 40 is effective in the closed position, while the other, arranged in the front region, the engagement member 40 is effective in the open position. The engagement elements 50 allow latching only in one direction, so that the stops for limiting the opening movement of the running rail 2 and stops for limiting the closing movement of the running rail 2 on the running rail 2, the middle rail 3 and / or the guide rail 4 are arranged. As in FIG. 8 is shown, the rolling elements 15 are in the extended position of the pullout guide 1 directly in the region of the spring element 40 and the engaging member 50 so that the locking in this area can be done with particular accuracy, since the adjacent rolling elements 15 for an exact positioning of the track 2, the center rail 3 and the guide rail 4 in this area provide.

In the FIGS. 9 to 11 is the one in the FIGS. 7 and 8th shown locking device shown in a slightly modified design. The spring element 40 comprises the vertically downward bendable web 41, as already in the FIGS. 7 and 8th is shown. In addition, the spring element 40 comprises an upper horizontal portion 42 and a stop 43 projecting upwardly from the running rail 2, which cooperates with a component which is placed on the running rail 2, for example a baking sheet. As a result, the spring element 40 has several functions on the running rail. The spring element 40 can be produced in a simple manner by punching and bending a metal sheet.

For locking on the engagement member 50, this is punched and bent integrally with the guide rail 4, wherein the engagement member 50 is formed as a V-shaped web with a tip 51 and two legs 52. When closing and opening the pullout guide 1, the spring element 40 with the bendable web 41 along the legs 52 on the tip 51 for locking proceed.

In the Figures 12 and 13 is one to the FIGS. 9 to 11 shown modified latching device, wherein the spring element 40 is formed identical to the vertical web 41. Only the engagement element 50 'is modified, since the legs 52', which are connected to one another at a point 51 ', are aligned at a different angle relative to the longitudinal direction of the guide rail 4 are. The angle α between the longitudinal direction of the guide rail 4 and the legs 52 'is greater than in the preceding embodiment, so that the latching forces are greater when passing over the engagement elements 50' by the spring element 40, that is, there is a stronger locking in the opening or closed position. Both in the embodiment of FIGS. 9 to 11 as well as at the Figures 12 and 13 is the engagement member 50 and 50 'formed symmetrically to a through the tip 51 and 51' running center plane, that is, the legs 52 and 52 'are aligned at the same angle to the guide rail 4.

In the in the Figures 14 and 15 In the embodiment shown, an engagement member 50 "is shown that includes a tip 51" that connects a flatter leg 52 "to a steeper leg 53". The engagement member 50 "is integrally formed with the guide rail 4 with the leg 52" oriented at an angle β to the longitudinal axis of the guide rail 4 and the leg 53 "at an angle δ. The angle β is in a range of, for example, 20 ° to 50 °, while the angle δ is larger and is in a range of 35 ° to 75 ° .Thus, the latching forces when passing over the spring element 40 of the engagement element 50 "can be made different in size. For example, the overrunning of the leg 53 "will be made heavier than the flatter leg 52", so that the holding forces are different when opening and closing the track rail.

In the Figures 16 and 17 A further embodiment of an engagement element 50 "'is shown, which is formed as a strip-shaped web integral with the guide rail 4. Also in this embodiment, a flatter leg 52"' is provided which extends at an angle between 15 ° to 30 ° to the longitudinal axis of Guide rail 4 extends, while an opposite leg 53 "'is steeper and extends at an angle between 20 ° and 35 ° to the longitudinal axis of the guide rail 4. The legs 52"' and 53 "'are in the abutting region at a tip 51st "' connected with each other.

In FIG. 18 another embodiment of a spring element 60 is shown, which comprises a bendable web 61 which is vertically aligned in the installed position. The bendable web 61 is connected via a step portion 62 to a vertical holding web 63, which is connected via a bent portion 64 with a sleeve 65. The sleeve 65 is optionally on the Fixed top of the slide rail 2 and forms a stop, as the stop 8 in the running rail 2 of FIG. 1 , Alternatively, the sleeve 65 can be plugged onto such a stop pin 8 for mounting the spring element 60.

In the FIGS. 19 to 21 a further embodiment of a spring element 70 or an engagement element is shown, in which a flat strip-shaped portion 71 on a running rail 2 or a guide rail 4 can be fixed. From this flat portion 71, a bent portion 72 extends to a receiving portion 73, which is connected via a step 74 with the portion 72. On the receiving portion 73, a cover 75 is mounted, which is made of a material having a low coefficient of friction. The cover 75 comprises a pin 76 which is inserted into an opening 77 on the bent receiving portion 73 of the spring element 70. The spring element 70 forms part of a latching device, in which on the cover 75, a sliding surface for the interaction of the spring element 70 is formed with an engagement element.

In the FIGS. 22 and 23 a further embodiment of a pullout guide is shown, in which a spring element 80 is fixed to the running rail 2. The spring element 80 cooperates with two engagement elements 50, which are formed as angular projections integral with the guide rail 4. The spring element 80 is mounted on the running rail 2 so that it protrudes in the longitudinal direction of the running rail 2 back. As a result, in a complete pull-out position, the running rail 2 can be arranged spaced apart from the guide rail 4 in the longitudinal direction, wherein latching is nevertheless enabled via the spring element 80. The engagement elements 50 can according to the FIGS. 9 to 17 be educated.

In FIG. 24 the spring element 80 is shown in detail. The spring element 80 is formed as an angular plate with a downwardly projecting spring bar 81 and a longitudinally extending strip-shaped holding portion 82. The length L of the holding portion 82 may be substantially greater than the height H of the spring bar 81. For adjusting the latching forces, it is possible for the spring bar 81 a determination of the holding portion 82 on the running rail 2 spaced from the spring bar 81 make, for example, only on the As a result, as a lever length for bending the spring bar 81, half the length of the holding section 82 would be available. The determination of the holding section 82 on the running rail 2, by force, form or material connection, for example by gluing or welding, can be selected according to the setting of the desired locking force.

In FIG. 25 a modified embodiment of a pullout guide is shown, in which the spring element 80 described above is fixed in the region of the running rail 2, that does not protrude to the rear. This arrangement of the spring element 80 has the advantage that the center rail 3 is even better protected by the running rail 2 and a more appealing appearance is given and the spring is protected by unintentional bending. The extension of the running rail in the rear wall of the open muffle facing region is advantageously carried out by the amount of the supernatant of the holding portion 82 in the direction of the rear wall of the open muffle facing region.

In the FIGS. 26 to 31 a further embodiment of a pull-out guide according to the invention is shown in which the same reference numerals are used for the same components. The pullout guide comprises a guide rail 4 which can be fixed to a side rail of a pullout guide or another element, a middle rail 3 and a movable running rail 2, which can be latched in an extension position by two latching devices. In the retraction position, no locking device is provided, but of course one or two locking devices can also lock the running rail 2 in the retracted position.

Each latching device has a spring element 80, which accordingly FIG. 24 is formed and has a substantially L-shaped contour. In this case, an elongate holding portion 82 and an angularly projecting spring bar 81 are formed, wherein the spring bar 81 can be latched with an engagement element 50. The engagement element 50 is formed as a V-shaped web, which is preferably stamped and stamped from a side wall of the running rail 2 or the guide rail 4. The holding portion 82 is fixed via attachment points 84, in this embodiment as welding points, to the running rail 2 and the guide rail 4, wherein the attachment points 84 determine the length of the lever travel with respect to the movement of the spring bar 81 and the non-fixed holding portion 82 and thus pretend the locking forces when driving over the engagement element 50.

In the in the FIGS. 26 to 31 shown embodiment, a latching device is arranged on opposite sides, wherein a first Locking device comprises a spring element 80 which is fixed to the running rail 2, while on the opposite side, a spring element 80 is fixed to the guide rail 4. The spring elements 80 are arranged offset in the longitudinal direction of the running rail 2 to each other and thereby ensure a reduced installation width of the pullout guide. Of course, it is also possible to fix the spring elements 80 both on the running rail 2 or the guide rail 4.

By means of the latching devices on opposite sides of the track rail 2, a substantially symmetrical introduction of force takes place, which largely avoids a rotational movement about an axis parallel to the track rail 2.

As in the Figures 29 and 31 is shown, the running rail 2 and the guide rail 4 have a substantially U-shaped cross section, wherein a leg of the U is formed longer and forms an inwardly angled end portion. In this case, three raceways for sets of spherical rolling elements 15 are provided, which are held along a Wälzkörperkäfigs 16. The center rail 3 has in cross-section substantially the shape of an "8", which has in order to form raceways for the spherical rolling elements 15 inwardly rounded portions.

As in the Figures 29 and 31 is shown, when passing over the V-shaped outwardly projecting engagement elements 50 with the obliquely to a tip 51 protruding legs 52, the spring bars 81 outwardly, ie away from the running rail 2 or the guide rail 4, bent. In this case, the spring webs 81 are arranged at an angle W to an adjacent surface of the running rail 2 or the guide rail 4, on which the outwardly projecting engagement element 50 is formed. The angle W is preferably in a range between 1 ° and 10 ° and provides for a defined sliding surface of the spring bar 81 on the tip 51 of the engaging member 50. The contact forces of the spring bar 81 against the engaging member 50 may not be so high that a premature Wear occurs and on the other hand not be so low that too low cogging forces are present.

In order to allow the angled arrangement of the spring bar 81, an outwardly protruding bulge 83 is formed between the holding section 82 and the spring bar 81, which ensures that the spring bar 81 is arranged adjacent to the holding section 82 farther out than at the protruding end.

The guide rail 4 is preferably fixed to a side rail, which is mounted in an oven. The side rails can be welded to the guide rail 4. Preferably, the welding takes place in such a way that at the same time the holding section 82 with the attachment points 84 is fixed to the guide rail 4.

In the illustrated embodiment, the spring elements and the engagement elements may be provided at least in contact areas with a coating, in particular a lubricant or a lubricant, to allow a smooth locking. The locking devices can be designed so that they are resistant to heat and survive temperatures of up to 250 ° without affecting the locking function. For the pyrolysis operation of a baking oven, the pull-out guides can also be designed up to 500 ° C. The pull-out guide according to the invention is determined in particular on a side rail of a baking oven, wherein other uses are possible, for example for furniture or other household appliances.
