Description

The invention relates to a roller carriage for the movable suspension of a sliding leaf on a running rail, and a sliding wing, which is suspended by means of a roller carriage along a running rail movable. Furthermore, the invention relates to a method for suspending a sliding sash on a roller carriage.

Known clamping connections generally have a sliding shoe clamping the clamping shoe, which is connected via a support pin hanging with a arranged on the clamping shoe, connected in a running rail roller carriage. Basically, attempts are made to dispense with holes or recesses in the sliding sash. For this purpose, there are various solutions to clamp a sliding wing to support and apply the required static friction force by a screw directly or indirectly on the door leaf.

The problem with laminated safety glass (VSG) is that, due to rheological properties, the intermediate film of PVB arranged between the glass panes begins to flow. The clamping force decreases gradually and the door can slip out of the clamp connection in the event of a shock. In order to install additional security here, it is known to provide fittings for laminated safety glass with a safety pin. This means that the door made of laminated safety glass is clamped, but still has a hole in the edge area, through which a bolt is inserted. When the door slumps, the bolt should take over the weight of the door.

This prior art has the disadvantage that the clamping connection fails abruptly during the movement of the door. The production of the holes in the glass takes place at the individual glass panes, ie before the panes are connected with the intermediate foil to VSG. Due to the large tolerances, the holes are offset from each other after the manufacture of laminated safety glass. Since the holes are not congruent one above the other, a non-circular opening remains in the laminated safety glass, in which a bolt or a screw is inserted. A positive connection of the bolt with the holes of both glass panes is thus not possible. Since the weight of the door is transmitted jerkily on the bolt, there is the possibility of glass breakage.

The EP1916370 A1 discloses the features of the preamble of claims 1, 5 and 9.

The DE4340690 discloses a clamping and gluing connection of a hinge to a glass pane.

It is therefore an object of the invention to provide a compact and inexpensive clamping connection for a sliding door, in which the aforementioned disadvantages do not exist.

The invention solves the problem with the teaching of claim 1, 5 and 9.

Further ausgestaltende features of the invention are the subject of the dependent claims.

The roller carriage according to the invention surrounds a front edge of the sliding leaf by clamping, the roller carriage having at least one fastening element for applying the clamping force to the surface of the sliding leaf, which simultaneously penetrates a bore of the sliding leaf. Due to the fact that the fastening element simultaneously produces the frictional connection, but is also part of the positive connection when the clamping connection fails, a very compact roller carriage is created, in which the glass breakage, especially in laminated safety glass, is avoided.

In order to produce the positive securing of the clamping connection, the roller carriage has at least one bore, by means of which a curable liquid can be filled into the bore. The curable liquid fills the remaining space of the hole in the sliding sash and generates after curing together with the fastener the positive connection.

The roller carriage has a carrier with two lateral cheeks, which together form a clamping chamber for receiving the sliding leaf. The fastener is mounted in both side cheeks and thus accessible from both sides.

One end face of the fastening element has a bore for filling the curable liquid, while the other end face is designed as an adjusting device in order to apply the clamping force to the surface of the sliding leaf. For this purpose, the fastening element has a shaft and a projection, wherein the bore exits by means of a channel or a further bore on the peripheral surface of the neck. The shank is configured to press a clamping plate disposed within the clamping chamber against the surface of the sliding sash. This design also contributes to the compact and inexpensive construction.

A further bore for filling the curable liquid may be arranged on a lateral cheek or the carrier, wherein each filling opening also serves for venting. In particular, the holes on the side cheek or on the carrier are also suitable to fill a section with curable liquid, which connects the bore with the front edge of the sliding leaf.

The sliding leaf according to the invention is suspended by means of a roller carriage along a running rail and has at least one arranged in the region of an end edge bore, wherein the sliding leaf is fixed non-positively on the roller carriage and within the bore a positive fastening of the sliding leaf is arranged on the roller carriage. According to the invention, the sliding leaf is mounted redundantly on the carriage, namely first on the clamping connection, and then - in the failure of the clamping connection - via a positive connection, wherein the bore in the sliding leaf is part of the positive connection.

The other part of the positive connection forms a fastener that simultaneously applies the clamping force. The fastener penetrates the bore of the sliding sash. When mounting the roller carriage to the sliding sash, a clamping ring arranged on the fastening element ensures that glass does not rest on steel. For this purpose, the clamping ring made of plastic, hard rubber, etc. is performed. The clamping ring is designed in terms of its dimensions so that a certain positive connection between the fastening element, clamping ring and bore of the sliding leaf is achieved without the subsequent filling with the curable liquid.

The subsequent filling of the remaining space in the bore of the sliding sash ensures a complete positive fastening of the sliding sash on the roller carriage. Another advantage is also that at the same time a backup of the fastener is done, which can not be solved in vibration and vibration.

According to the invention, the bores of the sliding leaf are connected by means of cutouts with the front edge. This allows a pre-assembled roller carriage with pushed through and screwed Fastening elements are plugged onto the sliding sash, which facilitates the installation on site significantly.

To ensure the positive connection, of course, this section is filled with a curable liquid.

The sliding leaf is in a preferred embodiment of laminated safety glass, in which a gradual loss of clamping force due to the embedded intermediate foil is possible.

The method for suspending a sliding leaf on a roller carriage, which is arranged movably along a running rail suspended on a wall or ceiling, comprises a roller carriage, which frictionally carries the sliding leaf in the region of an end edge, and a redundant form-fitting protection of the sliding leaf on the roller carriage.

For this purpose, the sliding leaf has at least one bore which serves for the positive suspension of the sliding leaf on the roller carriage. The counter-element is formed by at least one fastening element, which penetrates the bore of the sliding leaf, wherein the remaining space in the bore is filled up with a curable liquid.

For ease of assembly, the bore is connected by means of a cutout with the front edge of the sliding leaf, so that the roller carriage is pushed with the pre-mounted fasteners on the sliding leaf, by means of the fastening elements, the clamping connection is made and the bore and the neck is filled with a curable liquid.

The invention will be explained in more detail below with reference to a sketch of the prior art and an embodiment of the invention.

It shows:

FIG. 1:

a roller carriage in different views and a part of an associated sliding sash.

A sliding leaf 1 according to this exemplary embodiment consists of laminated safety glass 2 comprising at least one first glass pane 2 a, which is connected by means of an intermediate film 2 b to a second glass pane 2 c. In the region of the upper horizontal end edge of the sliding leaf 1 are spaced from each other two holes 3, 3a incorporated, which are connected via cutouts 4, 4a with the end edge. To suspend the sliding leaf 1 to a roller carriage 5, which is moved on or within a running rail, which is attached to a wall or ceiling, only the holes 3, 3a are necessary. However, the cutouts 4, 4a facilitate the assembly of the roller carriage 5. The sliding panel 1 can be made of any other material in addition to the material laminated safety glass, for example of metal, wood, plastic or a stone such as granite or marble. Furthermore, the sliding panel 1 may consist of a glass pane, which may be coated with a foil, or of multilayer laminated safety glass with, for example, three panes of glass and two intermediate foils. Particularly in the manufacture of laminated safety glass, the holes 3, 3a and cutouts 4, 4a are incorporated into the individual glass panes 2a, 2b prior to assembly, so that the bores 3, 3a and cutouts 4, 4a are offset with each other up to a part of 10 mm are. Due to these tolerances, a form-fitting protection by a bolt is not possible.

The basic structure of the roller carriage 5 is formed by a carrier 7 with two lateral cheeks 8, 9, which together form a clamping chamber 6 open at the bottom. The cross section of the roller carriage 5 is thus U-shaped or C-shaped. Within the clamping chamber 6, a continuous or a plurality of clamping plates 11 is arranged, which presses by at least one fastening element 15, 15 a einklemmenden sliding sash 1 against the lateral cheek 9. The clamping force is applied to the surface of the sliding leaf 1 by the fastening element 15, 15a. In order to avoid damage to the surface of the sliding leaf 1 and at the same time to achieve a higher adhesion, one or more elements are arranged as glass protection 12 within the clamping chamber 6. These elements may for example consist of cardboard, rubber, plastic or metals such as copper, etc.

Outside on the roller carriage 5, a roller block 25 is arranged or integrated, is rotatably arranged on the at least one support roller 26, 26 a. The roller block 25 can be arranged within the basic structure, ie within a lateral cheek 8, so that the lateral cheek 8 has a recess or recess or a feeder for receiving the roller block 25. However, the roller block 25 can also be arranged on the outside on one of the lateral cheeks 8, 9 or on the carrier 7. The roller block 25 further has an adjusting device 27, which allows a vertical adjustment of the suspended sliding leaf 1.

Furthermore, a stop and / or Aushebeschutz 28 is disposed on the roller carriage 5, which can be combined individually or with each other and by means of an adjustment 29 horizontally and / or vertically on the roller carriage 5 are adjustable.

The fastening element 15, 15a has at one end a shaft 19, 19a with an external thread, which leads to a complementary bore with internal thread of the clamping plate 11 fits, and is provided on an associated end face with an adjusting device 20, 20a, for example in the form of a hexagon socket or a slot. Furthermore, the shaft 19, 19a is screwed in the mounted state in a bore 10, 10a of the lateral cheek 8, which may have a gain or thickening for this purpose. The other side or the other end of the fastening element 15, 15a has a projection 18, 18a, which is likewise mounted in a bore 14, 14a of the lateral cheek 9.

On the front side of the projection 18, 18 a is a bore 17, 17 a incorporated, which exits on the peripheral surface of the projection 18, 18 a by means of a channel not shown at least once. In this embodiment, the bore 17, 17a extends along the longitudinal axis of the fastener 15, 15a and meets a transverse bore, which completely penetrates the projection 18, 18a on the peripheral surface. The projection 18 in turn is mounted in a through hole 14, 14 a of the lateral cheek 9. In the area of the mounting of the fastening element 15, 15a, a further bore 13, 13a is likewise arranged in the carrier 7. Each fastening element 15, 15a each has a clamping ring 16, 16a, which should facilitate assembly.

The assembly of the roller carriage 5 with the sliding leaf is carried out according to the following sequence: the roller carriage 5 with the preassembled fastening elements 15, 15a, on which already the clamping rings 16, 16a and the clamping plates 11, 11a sit with the fastening elements 15, 15a through the cutouts 4, 4a pushed into the bore 3, 3a, so that the roller carriage 15 with its lateral cheeks 8, 9 surrounds the sliding panel 1 in the edge region. The clamping rings 16, 16a take over the separation of the sliding leaf 1 of the fastener 15, 15a, so in this embodiment, the separation of the materials glass to metal.

The fastener 15, 15a takes on the side cheeks 8, 9 and the clamping plates 11, 11a, the function of low-voltage pre-fixing the fitting on the sliding leaf 1. The sliding wing 1 is thus held by the clamping force on the roller carriage supporting. Through the bore 17, 17a, a fast-curing liquid, e.g. Adhesive, plastic or sealing material in the fastener 15, 15 a filled, which exits on the inside of the bore 21, 21 a and the entire bore 3, 3a fills. Through the bore 13,13a also a fast-curing liquid is filled into the roller carriage 5, which fills the cutout 4, 4a. Thus, the entire glass cutouts are filled with the hardening liquid, so that large tolerance ranges can be compensated. After curing the liquid, e.g. of the adhesive, this takes over the function of separation metal / glass, since this has a lower modulus of elasticity than glass. Furthermore, the cured adhesive acts as an additional threadlocker, so that vibrations and shock loads can not lead to an independent release of the connection. The bores 13, 13a, 17, 17a and 21, 21 a serve to fill the bores 3, 3a and cutouts 4, 4a, but also to vent during the filling of the adhesive. Thus, the curable liquid does not leak from the bores 13, 13a, 17, 17a and 21, 21 a again, they can be equipped with a check valve.

The invention has the significant advantage that in case of failure of the non-positive clamping connection of the cured adhesive with the fastening element 15, 15a acts together as a positive connection, so that the sliding sash 1 does not sag on the fastener 15, 15a and thereby damaged. After the failure of the non-positive connection thus assumes the positive suspension of the sliding sash 1 on the roller carriage the entire weight of the sliding sash.
