Description

The invention relates to a sliding leaf arrangement comprising a stationary frame and a sliding leaf which can be displaced horizontally relative to the frame.

Such sliding leaf arrangements are known, inter alia, as sliding door or sliding window arrangements and can be part of building glazing, for example. The sliding sash is usually guided in a guide rail arranged on the upper cross member of the frame by means of one or more guide elements, e.g. guide rollers or guide sliders. The sliding panel can be moved manually, for example using a handle, or by motor.

In order to prevent unwanted entry into a building, for example in the course of an attempted break-in, with sliding leaf arrangements of the type mentioned at the outset, it is known to provide an anti-lift device to secure the sliding leaf against being levered out of the frame. For example, from the U.S. 3,714,738 a sliding wing arrangement is known in which wedge-shaped spacers are arranged between an upper cross member of the wing and an upper cross member of the frame in order to limit a lifting movement of the sliding wing in the vertical direction.

The present invention is based on the object of providing a sliding leaf arrangement which can be operated reliably and which provides effective burglary protection in a structurally simple and cost-effective manner. In addition, it is desirable to be able to flexibly adapt the sliding leaf arrangement to different installation situations.

The invention solves this problem with a sliding leaf arrangement having the features of claim 1. The sliding leaf arrangement comprises a stationary frame (fixed frame) and a sliding leaf that can be displaced horizontally relative to the frame. For example, the sliding leaf can be a door leaf (sliding door arrangement) or a window leaf (sliding window arrangement).

In the installed position, the sliding wing is coupled to at least one guide element on its upper wing cross member in relation to the direction of gravity. The sliding wing can preferably be coupled to two, three or more guide elements which are spaced apart from one another along a displacement axis of the sliding wing. The at least one guide element is held on a bolt, which extends in particular vertically. In particular, the bolt is attached to the upper wing cross member. In particular, the bolt comprises a shank section and a bolt head. The bolt head can limit displacement of the guide member in the vertical (axial) direction. The bolt can expediently be designed as a rivet pin.

The sliding leaf is guided in a guide rail arranged on the frame by means of the at least one guide element. For example, it is conceivable that the guide rail has an essentially U-shaped cross-sectional profile (open downwards in the installed position along the direction of gravity), with a base section and two leg sections. Then the at least one guide element can be accommodated between the leg sections. In particular, the at least one guide element can roll or slide off at least one of the leg sections in the course of a displacement movement of the sliding sash.

The sliding sash arrangement also includes an anti-lift device for securing the sliding sash against the sliding sash being levered out of the frame, for example as a result of an attempted break-in. The anti-lift device includes a blocking piece which is placed on a bolt head of the bolt. In this respect, the blocking piece is arranged on the wing side. The locking piece is designed in such a way that when it is placed on the bolt head, a gap in the vertical direction between the bolt head and the guide rail is at least largely bridged by the locking piece. In other words, the air in the vertical direction between the bolt head and the guide rail is bridged by the locking piece in such a way that a lifting movement of the sliding leaf in the vertical direction is limited. A distance between the locking piece and the guide rail is smaller than a distance between the bolt head and the guide rail.

An effective anti-burglary device is thus created with simple structural means, which can be produced inexpensively and can be easily adapted to different circumstances. It was recognized within the scope of the invention that the vertical gap between the bolt head and the guide rail or between the guide element and the guide rail can be different depending on a specific installation situation of the guide rail and the sliding sash and/or depending on a specific design of the guide rail and in the worst case can be so large that the sliding sash can be lifted out of the frame by lifting it vertically. The blocking piece according to the invention now bridges this gap, so that a lifting movement of the sliding sash is limited in the vertical direction. If - for example in the course of an attempted break-in - the sliding sash is lifted in a vertical direction, e.g. levered up with a crowbar, the locking piece is pressed against the guide rail and forms a stop which prevents further lifting movement of the sliding sash upwards.

The anti-lift device thus created can be installed with comparatively little effort, since only the locking piece has to be placed on the bolt head of the bolt. In addition, such an anti-lift device with a locking piece can be flexibly adapted. For example, it is conceivable that a set of locking pieces of different design, in particular different heights, is kept and a suitable locking piece is selected depending on the gap between the bolt head and the guide rail.

The blocking piece can expediently be designed in such a way that an at least slight gap remains between the blocking piece and the guide rail in the vertical direction, so that the blocking piece can be moved with the sliding leaf without contact with the guide rail. The locking piece is only used when the sliding sash is lifted, for example intentionally.

The locking piece can be placed on the bolt head in particular before the sliding sash is installed in the frame. The sliding sash can then be mounted in various ways. For example, it is conceivable that the lower end of the sliding sash is first inserted into the frame or into a running rail arranged on the frame and the upper guide rail is then placed on the sliding sash, in particular on the at least one locking piece. The sliding sash can then be pivoted into the frame in the vertical position and, as soon as the sliding sash with the guide rail is in the correct position in the frame, the guide rail can be fastened to the frame, for example screwed. It is also conceivable that the guide rail is formed in two parts, in particular by two separately formed guide rail segments that are arranged one behind the other along a subsequent displacement direction when installed as intended. A first guide rail segment can then be attached to the frame for the assembly of the sliding leaf. The sliding leaf can then be pivoted into the vertical in the area of the frame in which no guide rail is arranged and then pushed axially into the guide rail segment that has already been installed. The second guide rail segment can then be mounted on the frame.

The at least one guide element can be designed as a guide roller. The guide roller can preferably be mounted on the bolt (bearing bolt), in particular on a shank section of the bolt, such that it can rotate about a vertical axis of rotation. In the course of a displacement movement of the sliding leaf, the guide roller can then roll on at least one of the leg sections of the guide rail.

The at least one guide element can alternatively be designed as a guide slider. The guide slider can have at least one guide surface, in particular two guide surfaces running parallel to one another, by means of which the guide slider can slide off on at least one of the leg sections of the guide rail in the course of a displacement movement of the sliding sash.

Within the framework of an advantageous embodiment, the sliding wing can be coupled to at least one guide device on its lower wing cross member in relation to the direction of gravity. The sliding sash can then be guided by means of the at least one guide device on a lower running rail, arranged in particular on the lower frame cross member. Preferably, the guide device can be a carriage with one or more rollers, in particular one that carries the sliding leaf. In this respect, the sliding sash can be guided in the lower running rail by means of the at least one carriage. In particular, the sliding sash can have two carriages which are spaced apart from one another in a direction of displacement of the sliding sash. In such a configuration with a running rail, the blocking piece can then be dimensioned in such a way, in particular have such a height, that the vertical distance between an upper side of the blocking piece and the region of the guide rail arranged in the vertical direction above the blocking piece (i.e. the air between the blocking piece and the guide rail in vertical direction) is smaller than the distance between a lower edge of the at least one guide device or the at least one carriage and an upper edge of the running rail. In other words, the blocking piece can be dimensioned such that a vertical distance between the blocking piece and the guide rail is smaller than the vertical distance that would have to be overcome to lift the sliding leaf with its guide device out of the running rail. The locking piece is therefore dimensioned such that the at least one guide device or the at least one carriage does not have the barrel rail can be lifted and thus the sash cannot be levered out of the frame.

In principle, the locking piece can only be placed loosely on the bolt. However, in order to provide a certain amount of protection against slipping, it can be advantageous if the locking piece is coupled or connected in a form-fitting manner to the bolt head.

In concrete terms, the locking piece can have a receiving section for receiving the bolt head, in particular in a form-fitting manner. Such a locking piece can be held on the bolt head in a non-slip manner and yet be easy to assemble. In particular, the receiving section can have a negative shape of the bolt head (at least partially complementary configuration).

It can also be advantageous if the locking piece encompasses the bolt head radially. For example, the above-described receiving section can be delimited by a preferably circumferential edge, which radially encompasses the bolt head when installed as intended.

The locking piece can expediently be releasably connected to the bolt head in a non-destructive manner, optionally reversibly. This makes it possible to replace the blocking piece if necessary, e.g. if the gap between the blocking piece and the guide rail has changed, e.g. due to the building "settling", or if it becomes apparent during the installation of the sliding sash that the blocking piece initially selected is not does not fit perfectly. It is therefore possible to readjust the anti-jemmy device if necessary in order to ensure permanent, secure burglary protection.

In concrete terms, the locking piece can be releasably connected to the bolt head, for example via a clip connection. It is also possible for the locking piece to be connected to the bolt head by means of an adhesive connection, in particular so that it can be detached in a non-destructive manner. For example, it is conceivable that the locking piece has an adhesive film, e.g. an adhesive strip, on a contact surface, for example on the receiving section described above.

The locking piece can expediently be composed of several locking piece segments that are provided separately. In this respect, the assembled locking piece segments form the locking piece in their entirety. Such an embodiment makes it possible to set the overall height of the locking piece as required with little structural effort. The locking piece segments can preferably be stacked one on top of the other vertically, in particular along the axis of rotation of the guide roller. It is conceivable for the locking piece segments to have the same or different dimensions, in particular the same or different heights. The locking piece segments can be connected to one another, in particular so that they can be detached in a non-destructive manner. For example, it is conceivable that the locking piece segments each comprise a receiving section for receiving a further locking piece segment and/or a receiving section for receiving the bolt head. It is also possible for a base segment to be placed on the bolt head and for one or more extension segments to be placed on the base segment. For example, it is conceivable that a set of a limited number of locking piece segments with the same or different heights is provided, from which the locking piece can then be assembled as required, e.g. to be able to compensate for different profile shapes of the guide rail.

The locking piece can be cylindrical, in particular in the form of a vertical circular cylinder. Such a blocking piece can be advantageous in particular when the guide element is designed as a guide roller. In concrete terms, the locking piece or the locking piece segments can be designed as a turned part or plastic injection-molded part, which promotes simple and cost-effective production. The blocking piece can also be angular, preferably quadrangular, for example cuboid or cube-shaped.

The locking piece can also be designed as a sleeve. In particular, an inner diameter of the sleeve can correspond to an outer diameter of the bolt head or be dimensioned slightly smaller. Then the locking piece can be clamped to the bolt head. The sleeve can optionally be closed at one end. In this respect, the blocking piece can be designed as a cap.

Expediently, the blocking piece can be arranged at a distance from the guide element. In an embodiment of the guide element as a guide roller, the locking piece cannot be coupled to the guide roller in a rotationally fixed manner. When installed as intended, the locking piece does not rotate with the guide roller, e.g. when the guide roller rolls off the guide rail.

The at least one guide element, the guide rail and the at least one locking piece can advantageously be arranged between an upper frame cross member of the frame and an upper wing cross member of the wing in relation to the direction of gravity. As a result, these are at least one guide element ment, the guide rail and the at least one locking piece from environmental influences such as rain, dust, dirt or the like. Largely protected.

The object mentioned at the outset is also achieved by a locking piece according to claim 12 . The locking piece is designed to be used in a sliding leaf assembly as described above. In this respect, the blocking piece can be further developed, as described above in connection with the sliding leaf arrangement.

In particular, the locking piece can have a receiving section for receiving the bolt head, in particular in a form-fitting manner. The locking piece can optionally have an adhesive film, in particular adhesive strips. The locking piece can be designed as a sleeve. The locking piece can be formed from a plurality of separately provided locking piece segments, which can have the same or different dimensions. The locking piece can be designed as a turned part or a plastic injection molded part. The locking piece can be designed as a sleeve. Optionally, the sleeve can be closed at one end (cap). The locking piece can be cylindrical, cuboid or cube-shaped.

1 FIG. 12 shows a sliding door assembly, designated generally by the reference numeral 10. FIG. The sliding door assembly 10 includes a stationary frame 12 (fixed frame 12, in 1 shown with dashed lines) and a sliding leaf 14 that can be displaced horizontally relative to the frame 12 (cf. double arrow labeled with reference number 13).

The frame 12 has, for example, a fixed field 16, in particular a glazed one, which is marked with a diagonal cross in the drawing. The frame 12 includes a lower frame rail 18, an upper frame rail 20 and two vertical frame rails 22,24.

The sliding sash 14 has a sash frame 26 which delimits a sash panel 28, e.g.

How out 2 B As can be seen, a running rail 38 is arranged on the lower frame cross member 18 . Two carriages 40 spaced apart from one another along the direction of displacement 13 are arranged on the lower cross member 32 of the wing and run with respective rollers 41 in the runner rail 38 . The carriages 40 form a lower guide device 42. The carriages 40 can, for example, in 1 be arranged in the areas of the sliding leaf 14 shown in dashed lines and denoted by reference numeral 40′.

A guide rail 44 is arranged on the upper frame cross member 20 (cf. 2a) . In the example shown, the guide rail 44 has an essentially U-shaped cross section with a base section 46 and two side sections 48, 50 protruding orthogonally therefrom.

The sliding wing 14 is coupled at its upper wing transverse beam 30 to two guide elements 52 which are spaced apart from one another along the direction of displacement 13 and by means of which the sliding wing 14 is guided in the guide rail 44 (cf. also 3 ). The guide elements 52 can, for example, in 1 be arranged in the areas of the sliding leaf 14 shown in dashed lines and denoted by reference numeral 52′. It is also conceivable that the sliding leaf 14 is coupled to three guide elements 52 .

The guide elements 52 are in the in the 2 until 4 examples shown as guide rollers 53 formed. How out 4 As can be seen, the respective guide roller 53 is held by means of a bolt 54 on a fastening part 56, which in turn is on the upper wing cross member 30 is fixed, for example by means of appropriate fastening screws. The guide roller 53 is rotatably mounted on a shank section 58 of the bolt 54 about a vertical axis of rotation 60 . An axial (vertical) sliding movement of the guide roller 53 (in 4 "up or down") is limited on the one hand by a bolt head 62 of the bolt 54 and on the other hand by a contact section 64 of the fastening part 56. The bolt 54 can, for example, be held with a connecting section 66 in a corresponding receptacle 68 of the fastening part 56. By way of example and preferably, the bolt 54 can be designed as a rivet pin 54 .

As in 2a As shown, a gap 70 is formed between the base portion 46 of the guide rail 44 and the bolt head 62 . In order to bridge this gap 70, according to the invention a locking piece 72 is placed on the bolt head 62 of the bolt 54 in the vertical direction. As in the 2a and 4 shown, the blocking piece 72 is dimensioned such that a certain gap 74 remains between the blocking piece 72 and the guide rail 44 in the vertical direction, but this is smaller than the gap 70 without a blocking piece. In this respect, a distance d' _o between the upper side 76 of the locking piece 72 (cf. 5 ) and the base portion 46 of the guide rail 44 is less than a distance d _o between the top of the bolt head 62 and the base portion 46 of the guide rail 44.

The locking piece 72 is also dimensioned such that the distance d' _o between the upper side 76 of the locking piece 72 and the base section 46 of the guide rail 44 is smaller than a distance d _U between a lower edge 78 of the carriage 40, in particular a lower edge 78 of the rollers 41 , and an upper edge 80 of the running rail 38. In this respect, the sliding leaf 14 cannot be lifted out of the running rail 38 by lifting it vertically. In this respect, the locking piece 76 forms an anti-lift device 82 for the sliding sash 14.

In the example shown, the locking piece 72 is cylindrical and has a receiving section 84 for receiving the bolt head 62 (cf. 5 ). How out 5 As can be seen, the receiving section 84 is delimited by a preferably circumferential edge 86 which, when installed as intended, encompasses the bolt head 62 radially (cf. 2a and 4 ). The blocking piece 72 is in particular arranged at a distance from the guide roller 53 so that the blocking piece 72 does not rotate with the guide roller 53 .

The locking piece 72 can only be placed loosely on the bolt head 62 . However, it is also conceivable for an inner diameter 88 of the receiving section 84 to be dimensioned slightly smaller than an outer diameter of the bolt head 62, so that the locking piece 72 can be placed onto the bolt head 62 in a clamping manner.

In the case of configurations that are not shown, it is also possible for the locking piece 72 to be connected to the bolt head 62 by means of an adhesive connection or a clip connection. For example, the locking piece 72 can have an adhesive film, for example an adhesive strip, on its contact surface 90 . The blocking piece 76 can also be designed in several parts, for example composed of the above-mentioned blocking piece segments.

6 shows a further embodiment of the sliding leaf arrangement 10, in which the guide elements 52 are designed as guide slides 92. The guide sliders 92 are held on a bolt 54 and a fastening part 56 in a manner analogous to the guide rollers 53 described above.

How out 6 As can be seen, the guide slider 92 has a first guide surface 94 and a parallel second guide surface 96 . In the course of a displacement movement of the sliding leaf 14, the guide slider 92 can slide off with at least one of the guide surfaces 94, 96 on the guide rail 44.

The locking piece 72 can be analogous to that described above with respect to the 2 until 5 described be trained. In the case of configurations that are not shown, the blocking piece 72 can also be angular, for example cuboidal. The guide slider 92 can, for example, have a receptacle 98 for receiving the locking piece 72 .
