Description

Running parts and furniture accessories for guiding furniture parts in the guiding direction via guide rails

technical field

The invention relates to a running part for guiding furniture parts in a guiding direction via a guide rail, a furniture fitting with the running part, and furniture with the furniture fitting.

Background technique

A furniture part in the form of a sliding partition wall with strips formed on the bottom side is known from DE 43 30 152 A1. Located adjacent to the bar is a hook which engages in a resiliently mounted guide element with sliding grooves. Due to the elastic support of the guide element, the engagement between the hook and the slide groove can be released by lifting the guide element.

A sliding door is known from DE 20216481 U1, which is guided via two running parts in two guide rails of furniture. The first of the two running parts is mounted elastically on the furniture part, while the second running part is mounted adjustably in its position relative to the furniture part. If the second running part is arranged by means of its position relative to the furniture part, the first running part can be automatically adjusted in its position to the furniture part due to the resilient mounting of the first running part.

A furniture part in the form of a sliding door is known from US Pat. No. 5,845,363A, which is guided on guide rails via running elements. The running part is elastically mounted on the furniture part. The spring acts against the load exerted by the furniture part on the running part and presses the running part reliably against the guide rail even in the event of an insufficient load. Thereby effectively preventing the running parts from derailing from the guide rail.

Contents of the invention

The object of the invention is to improve known furniture or furniture parts and to simplify installation.

This object is achieved by the features of the independent claims. Preferred embodiments are the subject of the dependent claims.

According to one aspect of the invention, a running part for guiding a furniture part via a guide rail in a guiding direction comprises a holder which can be rigidly connected to said furniture part to be guided; The position is held displaceably between the mounting position on the holder at an angle to the guiding direction, and the locking bar is guided along the guide rail in the guiding position. The running elements on the furniture part should ensure reliable guidance of the furniture part by the guide rail.

Before being inserted into the corresponding guide rail, the holder can also first be fastened to the furniture part together with another running part. Once another running part has been inserted into its guide rail, the locking bar of the indicated running part can be pushed into its installation position, in which the sliding door can be pivoted, and then the locking bar is inserted into the recess on the guide rail. in the slot. The pre-installed locking strip can be found by touch by the fitter during the installation of the furniture part, which is why it does not need to be arranged in the fitter's field of vision during installation.

Within the scope of the indicated running components, the angular (preferably right-angled) displacement relative to the guiding direction can have any desired curve progression, for example a straight or curved curve progression.

The running part also includes a restoring part, via which the locking strip is pretensioned on the holder in the guide position. The guide position is predetermined in this way as the standard position for the locking strip. The locking bar must then be quickly moved by the fitter during installation from its guiding position to the installation position and automatically moved after installation (after release by the fitter) into the locked position.

The running part also includes a blocking element, by means of which the displacement of the locking strip from the guiding position can be blocked. Inadvertent disassembly is thereby prevented and also movement of the locking bar from the guide position to the installation position in the event of failure of the restoring means is prevented.

The blocking element can act essentially on the basis of any connection principle, such as a friction-lock connection or a material bond connection. The blocking element particularly preferably comprises a first rigid locking element on the locking strip and a second rigid locking element on the holder, the second rigid locking element being arranged in a complementary manner to the first rigid locking element , the rigid locking element is formed to block displacement of the locking bar against the locked position via a positive locking fit. The rigid locking elements arranged on the holder are preferably formed with a special geometry in order to ensure an even better rigid locking fit. This positive locking fit can be opened and closed again at any time, so that, for example, the furniture part can be removed from the guide rail in a simple manner, should the furniture part require repairs.

In the indicated preferred embodiment of the running part, said first rigid locking element and/or said second rigid locking element are movably mounted at an angle, preferably at a right angle, to the direction of displacement of said locking bar, by In this way, any desired opening and closing positive locking fits can be implemented in a particularly simple manner.

In the indicated embodiment of the running part, the positive locking fit acts in the direction of the guiding direction and the locking position. The blocking element thus counteracts not only the movement of the locking strip against the locked position, but also the movement of the blocking element itself. The movement of the blocking element can be caused by a force acting on the blocking element in the guiding direction, for example in the aforementioned vibrations during impact of the furniture part in the form of a sliding door against the boundary. The release of the locking strip is effectively prevented by the aforementioned preventing movement of the blocking element.

In a further embodiment of the indicated running part, said first rigid locking element and said second rigid locking element are arranged as latching elements. The blocking element can thus be actuated without tools.

In an additional embodiment, the indicated running part comprises a guide element for guiding the locking strip in the direction of displacement of the locking strip in the area of contact with the guide rail.

According to a further aspect of the invention, a furniture fitting is provided, in particular for sliding doors, wherein a base body is guided between a first rail and a second rail, wherein a second rail connected to the base body is provided. a running member to guide the substrate on the first rail, and a second rail to guide the substrate on the second rail, the second rail being spaced apart from the first running member and fixed to the base.

In another embodiment, the indicated furniture part comprises a limiting element arranged on said first guide rail to limit the movement of said first running part in said guiding direction, thereby ensuring that the furniture part cannot leave the guide rail guide. The limiting element can be arranged in an at least partially deformable manner, preferably elastically deformable, in order to reduce vibrations in the guiding direction.

According to a further aspect of the invention, a piece of furniture comprises a movable furniture part which is displaceably mounted via a furniture fitting according to the invention.

As seen in displacement direction 22 , a holding element 38 is formed at the upper end of mounting holder 20 , through which holding element adjusting screw 28 can be screwed.

In the present embodiment, the support element 24 is formed by a sheet metal part 40 , the boundary area of which support element 24 is partly reinforced by a bulge 42 . Slots 44 are formed in the sheet metal part 40 . A counter-bearing element 46 is formed at the upper end of the sheet metal part 40 (as seen in the direction of 22 ), against which the adjusting screw 28 rests in order to set the relative position between the mounting holder 20 and the support element 24 . An opening 48 is also formed in the sheet metal part 40 into which a shaft 50 is inserted for mounting the bottom roller 26 . Bottom roller 26 has a diameter 52 .

Finally, a guide plate 54 is arranged on the underside of the support element 24 (as seen in the displacement direction 22 ), onto which a protective cap 56 is inserted.

Reference is made here to FIG. 4 , which shows a perspective partial view of the first running part 12 of FIG. 2 on the bottom rail 8 .

The bottom rail 8 comprises a guide slot 58 which opens towards the inner space 60 of the rail. The bottom rail 8 is shown partially exposed in FIG. 4 to better illustrate the inner space 60 of the rail. As seen in the guide direction 16 , at one end of the guide rail 8 the inner space 60 of the rail is sealed off by a limiting element 62 which forms a limiting stop for the first running part 12 .

The guide plate 54 of the support element 24 , covered in more detail (not shown) by a protective cap 56 , engages via a guide slot 58 in the inner space 60 of the rail and is guided therein as a sliding bearing. An annular protrusion 64 formed on the outer circumference of the bottom roller 26 is inserted into and guided in the guide slot 58 .

The limiting element 62 as shown in FIG. 5 comprises a fastening section 66 and a stop section 68 . The limiting element 62 is fastened to the fastening section 66 in the inner space 60 of the rail by means of screws 70 . The stop section 68 is mounted elastically to a lesser extent on the fastening section 66 via a spring section 72 .

The retaining section 68 includes a receiving channel 74 , which extends in the guiding direction 16 and in which the guide plate 54 covered by the protective cap 56 can be accommodated. Said receiving channel 74 comprises a conical portion 76 transverse to the guiding direction 16 in order to latch the guiding plate 54 covered by the protective cap 56 in the closed position.

FIG. 6 shows the upper rail 10 arranged in a stationary manner relative to the furniture body 6 . The upper rail 10 comprises openings 77 for the screws 18 fixed to the furniture body 6 .

The upper running part 14 includes a holder 78 fixed to the door body 21 of the sliding door 4 via three screws 18 . A locking bar 80 is displaceably held on the holder 78 of the upper running part 14 in the vertical displacement direction 22, wherein an upper roller 82 placed on the upper guide rail 10 is rotatably mounted at one end of said locking bar 80 , so that when the sliding door 4 moves in the guiding direction 16, the upper roller 82 rolls on the upper guide rail 10.

In order to establish and maintain the contact of the upper roller 82 with the upper guide rail 10 , in this embodiment a blocking element 84 is provided which blocks the relative movement between the locking bar 80 of the upper running part 14 and the holder 78 of the upper running part 14 . The locking bar 80 of the upper running part 14 can be displaced in the displacement direction 22 until the upper roller 82 comes into contact with the upper rail 10 . In this state, the relative movement between the locking strip 80 of the upper running part 14 and the holder 78 of the upper running part 14 can be prevented by the blocking element 84 .

Reference is thus made to FIG. 7 , which shows an exploded view of the second running component of FIG. 6 .

The holder 78 of the upper running part 14 comprises three pins 87 on the bottom plate 85 each having a through opening through which the screws 18 can be inserted. The tip of the pin 87 may be located on the door body 21 such that the pin 87 defines a gap between the bottom plate 85 and the door body 21 .

Similar to the support element 24 of the bottom running part 12 , the locking strip 80 of the upper running part 14 is formed from a sheet metal part 89 , the border area of which locking strip 80 is also partly reinforced by raised portions 91 . Similar to the support element 24 of the bottom running part 12, a slot 93 is formed in the sheet metal part 89 of the upper running part 14, into which the pin 87 of the holder 78 of the upper running part 14 is inserted, so that the upper running part The locking bar 80 of 14 is mounted displaceably in the displacement direction 22 relative to the holder 78 of the upper running part 14 .

Similar to the sheet metal part 40 of the bottom run 12 , an opening 95 is provided for supporting the upper roller 82 of the upper run 14 by a sheet metal part 89 into which the shaft 50 is inserted to support the upper roller 82 .

As seen in the displacement direction 22, similar to the sheet metal part 40 of the bottom running part 12, in this embodiment a guide plate 97 is formed on the upper side of the sheet metal part 89 of the upper running part 14, the guide The plates can be inserted into guide slots 58 on the upper rail 10 . The features of the bottom rail 8 as shown in FIG. 4 may alternatively or additionally be transferred to the upper rail 10 .

According to FIG. 7 , the blocking element 84 on the holder 78 of the upper running part 14 is mounted rotatably on a pivot bearing 88 of the holder 78 . The spring element 92 is arranged on one side of the pivot support 88 so that the pin 94 can be inserted into the pivot support 88 and also the pin 94 on the opposite side of the blocking element 84 can be inserted onto the holder 78 in the pivot support. Additionally, the blocking member 84 includes a rotary handle 96 on which the blocking member 84 may be held for rotation. Finally, the blocking element 84 comprises a rib-shaped engagement element 98 that can engage with a rib 100 on the sheet metal part 89 in order to prevent the locking strip 80 of the upper running part 14 from moving against the holder of the upper running part 14 against the displacement direction 22 78 sports. Ribs 100 are preferably formed with pitch angles 128, as shown in particular in FIG. 9d. This ensures a continuous increase in tightening torque during the pivoting of the rotary handle 96 to the closed position and a maximum positive-locking fit between the rib 100 and the engagement element 98 after the pivoting has been completed. In addition, the rib 100 and the engagement element 98 have a special saw-tooth shape, which engage one another during meshing and, in the case of overload, can especially absorb high forces.

For the mechanical support of this positive locking fit, a rest 101 can be formed on the locking bar 80 before turning the handle 96 in the displacement direction 22, which rest can be placed as a limit stop in the closed position of said blocking element 84 On the rotary handle 96 of the upper part, in order to additionally prevent the aforementioned movement of the locking bar 80 relative to the holder 78 against the direction of displacement 22 . At the same time, the rest 101 assumes the function of a height stop for the locking bar 80 during movement of the holder 78 and as an emergency element if the blocking element 84 fails during potential damage.

For the purpose of supporting the pressing of the upper roller 82 against the upper guide rail 10 , the upper running part 14 also comprises a spring 102 pretensioned against the displacement direction 22 and formed as a flat coil spring. The spring 102 can be hooked into a corresponding spring mount 104 on the side of the furniture fitting and can be mounted in a corresponding counter support 106 so that the sheet metal part with the roller 82 89 pre-tensioned. The locking bar 80 of the upper running part 14 can be moved across the handle part 108 against the direction of pretensioning of the spring 102 .

Referring to FIG. 8 , it shows a perspective view of an alternative sliding door 4 comprising an aluminum frame with filler elements instead of board-shaped wood material, the second running part 14 mounted on an alternative Selected sliding door 4 on.

The door body 21 includes an outer frame into which a filling member, for example one made of glass, is inserted. The corner connectors 112 are inserted into the frame bars 114 in the corners of the door body 21 . The fastening between the corner connector 112 and the frame bar 114 can be produced via a receiving bore 116 into which a screw 18 can be screwed.

In this embodiment, a fastening bore 118 is formed in one of the frame bars 114 , on which the guide member 120 can be fastened by another screw 18 via the fastening bore 118 . The locking strip 80 of the upper running part 14 can be guided in a guide gap (not shown) between the guiding part 120 and the frame bar 114 via the guide projection 123 on the sheet metal part 89 of the locking strip 80 of the upper running part 14 .

A partial view of the blocking element 84 on the upper running part 14 of FIG. 6 showing the mounting of the sliding door 9 on the furniture body 6 is shown in FIGS. 9 a to 9 d.

Prior to installation, the bottom run part 12 and the upper run part 14 are fixed to the bottom and upper sides of the door body 21 in the manner shown in FIGS. 2 and 6 .

The bottom running part 12 fixed to the furniture body 21 can then be inserted with its guide plate 54 inserted into the guide slot 58 of the bottom rail 8 so that the sliding door 4 can move in the bottom rail 8 in a guided manner.

Now the blocking element 84 can be opened on the upper running part 14 by rotating the handle 96 (as shown in FIG. 9 a ), the positive locking cooperation between the engagement element 98 on the side of the blocking element and the rib 100 arranged on the locking bar 80 can be released.

In the position shown in FIG. 9 a, the locking bar 80 of the upper running part 14 is in the upper position, in which the upper edge of the guide plate 97 of the upper running part 14 stands on the bottom edge of the upper guide rail 10. At a higher height (as seen in displacement direction 22). Therefore, the guide plate 97 cannot be inserted into the guide slot 58 of the upper rail 10 .

However, as shown in FIG. 9 b , the locking strip 80 of the upper running part 14 can assume a position relative to the holder 78 of the upper running part 14 , which will be referred to below as the mounting position. In the installed position, the locking bar 80 is moved downwards against the force of the spring 102 so that the distance 124 between the locking bar 80 and the sheet metal part 89 changes to a greater distance 126 . In the installed position, the guide plate 97 of the upper running part 14 is now located below the guide slot 58 of the upper guide rail 18 (as viewed in the direction of displacement 22), and thus can be moved by sliding the door 4 relative to the bottom guide rail 8. pivoting to be arranged below the upper rail 10 (as seen in the displacement direction 22). For example, the locking bar 80 can be pulled to the installed position by pulling the handle portion 108 .

Once the guide plate 97 of the upper running part 14 is arranged below the guide slot 58 of the upper guide rail 10, the locking bar 80 of the upper running part 14 can be pushed by the spring 102 in the displacement direction 22, so that the guide plate 97 of the upper running part 14 It can be introduced into the guide slot 58 of the upper rail 10 . Thus, the sliding door is locked in the guide rail 8, 10 (as seen at an angle to the guide direction 16) and no longer falls out of said rail.

The blocking element 84 can then be closed until the rotary handle 96 hits the rest 101 circumferentially. Thus, the positive locking fit between the engaging element 98 and the rib 100 arranged on the locking bar 80 is partially closed. The locking bar 80 can thus be fixed in the locked position.

In FIG. 10 , the engagement element 98 and the rib 100 are shown in detail, which engage during rotation of the blocking element 84 , thereby preventing movement of the sheet metal part 40 relative to the locking strip 80 .

The adjusting screw 28 can be used particularly advantageously to set the height of the sliding door 4 . By pivoting the rotary handle 96 the blocking element 84 is first released on the upper running part 14 . The desired height adjustment of the sliding door 4 can then be carried out via the adjusting screw 28 on the bottom running part 12 . At the same time, the upper running part 14 automatically adjusts itself before the blocking element 84 moves back into the locked position.
