Description

Sliding element with anti-slip device suspended and moved on a rail by means of supporting rollers

Technical Field

The invention relates to a sliding element which is suspended and displaced on the upper side of a rail by means of supporting rollers or runners, wherein the rail is connected to a substructure or the like by means of rail holders which engage the rail from below, and wherein the sliding element further comprises a locking device which is located below the rail and which is arranged on the sliding element or on a mounting thereof.

Background

Between the slide element and the lower edge of the rail there is usually a free space through which the entire slide element including the support rollers of the rail can be removed. Said free space may lead to an unintentional detachment of the sliding element under normal operating conditions. In order to avoid this, a plurality of anti-slip devices are arranged on the sliding element or its mounting, the outer contour of which facing the rail is at a very small distance from the outer periphery of the rail, so that the sliding element can only be removed after removal of the anti-slip devices. With such anti-slip means, the sliding element can pass over the shoe holder supporting the shoe, which can create difficulties if the shoe holder is located on the lower portion of the shoe.

US-PS4905345 discloses a slide element which is suspended for movement in a guide rail by an attachment plate disposed between the slide element and a support roller. The guide rail is inserted into a U-shaped support profile which is open at the top and, like the support profile, is formed from several sectional parts. The sectional pieces of the support profile are supported in the region of the interface by an angular bracket, the horizontal flange of which engages under the bottom edge of the support profile. In which there is not provided an anti-slip means for preventing the sliding member from being accidentally dropped.

The known sliding element suspended from the connecting plate has a plurality of anti-slip devices which are rigidly connected to the connecting plate and engage with a portion of its outer contour with clearance around or below the outer contour of the slide rail. Here, on the one hand, it is ensured that the necessary play is passed over the rail holder; on the other hand, the anti-dropping effect is also required to be ensured.

Disclosure of Invention

The object of the invention is to propose a solution according to which the anti-slip device engages the rail from below with little play during the movement of the sliding element, possibly without any play, and engages the rail and the rail holder from below when passing over the rail holder, such that the sliding element is locked against slipping.

To this end, the invention provides a sliding element which is suspended and moved on the upper side of a rail by means of supporting rollers or runners, wherein the rail is connected to a substructure or the like by means of rail holders which engage the rail from below, and wherein the sliding element further comprises a retaining device which is located below the rail and which is arranged on the sliding element or on a mounting thereof, characterized in that: the locking device has a locking member which is elastically adjustable relative to the rail and which is deflected when the rail-holder is moved over, said locking member being mounted so as to be pivotable about an axis extending in the direction of travel of the sliding element at right angles to the direction of travel of the sliding element.

According to the invention, the anti-slip device has a blocking element which is elastically adjustable relative to the rail and can be deflected when the rail-holder is passed over. The solution according to the invention ensures that the blocking element runs on the rail continuously against the rail or with a small clearance in such a way that the sliding element cannot fall out of the rail. On the other hand, due to the elastic adjustability of the blocking element relative to the rail, the blocking element, although moving back when passing over the rail holder, can nevertheless retain the features of the anti-slip device.

According to a particularly preferred embodiment of the invention, the locking device has a blocking element which projects from its support facing the rail and is spring-loaded adjustable relative to the rail and prevents the sliding element from falling out, said blocking element being biased into the support of the locking device against the force of a spring when the blocking element is released when the rail holder is passed over. According to the above feature, the locking element inserted into an, for example, groove-shaped receptacle of the anti-slip device holder is inserted into the holder in such a way that the locking element is locked into the holder against a counter pressure during the travel of the locking element along the rail, in order to achieve the anti-slip effect. In contrast, when a rail holder engaging the rail from below is passed over, the blocking element is deflected against the spring force by being sunk into the holder of the anti-slip device so far that the part of the rail holder engaging the rail from below can be driven over, while the anti-slip effect is maintained. The anti-falling device can continuously keep in contact with the sliding rail and the sliding rail fixer.

The locking element is preferably inserted into a groove of the anti-slip device holder at right angles to the direction of travel of the sliding element, so as to be pivotable about an axis extending in the direction of travel of the sliding element, wherein the pivoting path of the locking element is delimited in both directions of rotation by bearing surfaces provided on the locking element.

When the slide rail is passed over, the pivoting path of the locking element is defined in a position preventing the sliding element from falling out, in that a locking lug of the locking element is arranged outside the central longitudinal axis of the slide rail on the side of the slide rail facing the substructure and adjacent to the outer periphery of the slide rail. In contrast, when the slide rail holder is passed over, the pivoting path of the locking member which occurs in the opposite direction is defined in such a way that the locking lug of the locking member abuts against the slide rail holder with a sufficient pivoting path play.

In accordance with the above features, a locking device is provided in a sliding element of the type mentioned at the outset, which locking device has a resiliently resettable locking member, the resetting capability of which can be locked into the locking device holder when the sliding element is moved over a rail, and the resetting capability of which is released only when the sliding element is moved over a rail holder.

The spring-loaded positioning of the blocking element in the anti-slip device holder is preferably achieved in that the anti-slip device holder and the blocking element have concentric bores into which the blocking element can be rotatably inserted by means of a pin which passes through the concentric bores.

In order to achieve a low noise and no impact when the blocking element passes over the rail holder, a guide ramp is provided on the surface of the blocking element facing the rail and/or the rail holder, and the pivoting movement of the blocking element relative to the carrier is guided through the guide ramp.

In principle, the retaining device can be fixed to a connecting plate supporting the sliding element in any desired manner, preferably by means of an insertion tongue, a dovetail joint or the like provided on the retaining device.

Detailed Description

In fig. 1, a glass wall is denoted by 1, which in this exemplary embodiment is formed by two sliding elements 2 guided on a rail 5, which are movable in the direction of the arrow L. The sliding element 2 is guided on the upper side 6 of the rail 5 by means of the web 3 and the support rollers 4. The slide 5 is fixed to a substructure 10 by means of slide holders 7 (see fig. 2 and 3).

As shown in fig. 2 and 3, the connecting plate 3 is connected to the sliding element 2 by means of a point holder 8, wherein, in this embodiment, a housing 9 is provided between the connecting plate 3 and the sliding element 2, which housing abuts against the connecting plate 3. A locking device 11 is connected to the connecting plate 3 and the housing 9 by means of a screw connection 29, the part of the carrier 13 of the locking device 11 being configured on its upper side in a manner not shown as a box-shaped recess, so that a locking element 12 can be inserted into the box-shaped recess. The locking member 12 is prestressed in the direction of the arrow B by means of a spring 14, as shown in fig. 5, and assumes the position shown in fig. 2 when passing over the slide rail 5. Wherein the locking lug 20 of the blocking member 12, which is adjacent to or abuts the outer periphery 22 of the sliding rail 5, is located at a distance marked x from the central longitudinal axis 21 of the sliding rail 5 and locks the sliding element 2 in a fall-proof manner. A pivoting path of the locking element 12, which is marked in the direction of arrow B, is blocked in this position, so that the locking element 12 cannot rotate further about its axis 17.

When the slide holder 7 is passed over, the locking element 12 is deflected in the direction of the arrow C by rotation about the axis 17 in the manner to be explained below and can be moved over the part of the slide holder 7 that engages under the slide 5, while the locking lug 20 engages with the part of the slide holder 7 that engages under. The pivoting path in the direction of the arrow C is determined such that the blocking element 12 can be fully inserted into a groove, not shown, of the carrier 13.

Fig. 4 to 7 show that a guide ramp 26 is provided on the side 25 of the locking element 12 facing the sliding rail 5 and the sliding rail holder 7, which guide ramp facilitates the pivoting of the locking element 12 from the position shown in fig. 2 into the position shown in fig. 3 and enables a shock-free passage over the sliding rail holder 7.

In the side view of the locking element 12 according to fig. 5, a spring 14 is arranged, the leg 15 of which is supported on the bottom of a not shown groove of the support 13 and the leg 16 of which is supported on the locking element. The through hole 24 in the locking member 12 is concentric with the corresponding hole 23 in the bracket 13, so that a pin, not shown, can be inserted into the holes 23 and 24. Fig. 5 further shows that the blocking element 12 has bearing surfaces 18 and 19, wherein the bearing surface 19 together with a bearing surface, not shown, of a not shown groove of the carrier 13 forms the pivot limit of the position shown in fig. 2, and the bearing surface 18 forms the final pivot limit of the position shown in fig. 3.

FIG. 6 shows the latch member as viewed from the substructure (arrow direction A); fig. 7 is a top view of fig. 6.

In the embodiment of fig. 8, the bracket 13 of the anti-disengagement means 11 has a tongue 27 insertable in a corresponding groove of the connection plate 3; in the embodiment of fig. 9, the securing means is configured as a dovetail joint 28.
