Abstract

The sliding window or sliding door (10) has a window frame (20) enclosing surface, two wings (30,40), where one wing is designed as sliding wing and is adjustably held in the window frame and a key lock, which has two segments (51,55). Two segments of the key lock are arranged in the wings.

Description

The present invention relates to a sliding window or a sliding door, which or a frame, at least two wings and a closing device having at least two segments, wherein at least one wing is formed as a sliding sash and slidably held in the frame.

A sliding window or a sliding door with such a locking device is basically known from the building technology. The locking device should serve to prevent a burglary, unauthorized opening of the sliding window or the sliding door. Usually this is the sliding window sash or sliding sash opposite the fixed sash secured by a bolt against displacement. Such a bolt usually consists of two segments, one segment of which is arranged in the frame profile of the fixed window sash and a segment in the frame profile of the sliding window sash. In the closed state of the window or the door those portions of the frame profiles in which the respective segments of the bolt are arranged, aligned with each other, as a result, the two segments of the bolt can be brought into operative engagement by locking. In other words, the two segments of the bolt are usually designed such that after locking the two locking segments relative to a displacement of the sliding sash the fixed window sash is no longer possible. By known from the prior art locking devices with a bolt of two segments, it is not necessary to attach two separate bars symmetrically on the outside of the window frame. Rather, a single bolt consisting of two segments is used, wherein a parallel displacement of the two window sash against each other is prevented by the two segments of the bolt connect the two sashes in the closed state of the window or the door. In other words, in the known solution, the bolt blocks the sliding path of one wing past the other.

However, in the event of burglary, if a lever, e.g. a crowbar, attached centrally between the frame profiles of the two window sash and exerted a force perpendicular to the window surface, the two frame profiles can be easily deformed, so that they are then spaced apart so far that the two segments of the bolt are no longer engaged , It is then possible to move the sliding window and open the window.

On the basis of this problem, the present invention has the object, a sliding window or a sliding door of the type mentioned in such a way that the burglary is increased, without the need for the frame construction consuming and difficult to do.

This object is achieved with a sliding window or a sliding door of the type mentioned above in that a closing device is provided which has at least two segments, wherein the at least two segments of the closing device are each arranged in the wings such that the segments of the closing device in the closed State of the sliding window or the sliding door are in operative engagement with each other, wherein the closing device is designed to receive forces of the sliding window or the sliding door in the closed state, which act on the wings perpendicular to a surface enclosed by the frame and in the sliding direction of the sliding leaf.

The solution according to the invention has a number of advantages over the known sliding windows or sliding doors. In particular, the segments prevent the closing device in the closed state of the sliding window or the sliding door that the sashes are moved against each other. At the same time, however, the closing device absorbs forces that are exerted perpendicular to the surface enclosed by the frame. In the described case of a break-in is prevented by the fact that the two segments of the closing device can move apart under the force of the lever and lose the engagement with each other. Therefore, it is not necessary to additionally stiffen the construction of the wings.

Advantageous developments of the invention are specified in the subclaims.

For example, it is provided that the at least two segments of the closing device are arranged rotatable relative to one another about an axis perpendicular to the surface enclosed by the frame. Furthermore, it is provided that the at least two segments of the closing device can be brought into two different states by rotation relative to the orientation of the sliding window or the sliding door, wherein the two segments are in operative engagement with each other in a closing state of the closing device and in an opening state of the closing device are mutually displaceable. It is therefore particularly easy to unlock or lock the window by rotation of the locking device.

In addition, the at least two segments of the closing device on two engagement surfaces, which can be brought in the opening state of the closure device by closing the at least one sliding leaf with each other in positive operative engagement, so that the two segments can absorb a tensile force perpendicular to the window surface. In this way, when closing the sliding window by moving simultaneously the two engagement surfaces of the two segments of the locking device brought into operative engagement with each other, without further additional operations.

Furthermore, the at least two segments of the closing device preferably have two engagement surfaces which, in the closed state of the closing device, are in a form-locking operative engagement with one another, which means that the two are displaced Segments against each other in the sliding direction of the sliding window prevented. As already described above, the two segments of the closing device can be brought by rotation relative to the sliding window in a closed state in which the displacement direction of the sliding window no longer coincides with the orientation of the direction of displacement of the two segments of the closing device to each other. It is therefore no longer possible, by exerting a tensile force on the sliding leaf to move these two segments against each other or to separate from each other. Characterized the window is secured against forces perpendicular to the window surface as well as against opening by moving simultaneously with a simple rotation of the closing device.

Furthermore, it is advantageous if the wings have receptacles in which the at least two segments of the closing device are rotatably mounted. Recordings, which are carried out for example by drilling, are easy to provide and allow actuation of the closing direction by simply turning.

In a further realization of the solution according to the invention, it is provided that the segments of the closing device have reinforcing means at ends facing away from one another. Thus, the transition of compressive forces exerted on the sliding sash and the fixed sash by, for example, a lever fitted between the window profiles, is improved on the closing device and reduces the risk of the material of the sash first yielding at this point.

For example, the aforementioned reinforcing means can be realized by reinforcing rings which are arranged between the respective wing and the respective segment of the closing device. These distribute the force over a larger area of the wings, are at the same time easy to manufacture and assemble and require no structural changes to the wing, so that the wing can be made for example of a profile, which is manufactured by continuous casting.

Furthermore, it is advantageous if the locking device is designed to be actuated by means of a key. The operation with a key is usually connected with a rotation, so that when using a key already the intended rotation of the segments of the closing device takes place. At the same time a key ensures that the locking device can not be done accidentally or in the event of burglary, for example, after destruction of the glass from the inside. In addition, the key also allows to provide an opportunity to operate the locking device on the outside of the window without this can be opened without authorization.

According to a further embodiment of the sliding window or sliding doors according to the invention, the closing device is designed such that it can be actuated with the aid of the key from the outside and inside of the sliding window or the sliding door. By a closing device which is operable from the outside and inside, it is possible that the window or the door can be closed from both sides, which of course proves to be useful especially in the case of a sliding door. Preferably, the segments are provided with identical keyholes to operate each of the at least two segments with the same key can.

In a further development of the sliding windows and sliding doors according to the invention, it is provided that the at least two segments can each be inserted in a bore through the wings. In this way, it is very easy to attach the at least two segments of the locking device to the wings of the sliding window or the sliding door. In addition, the at least two segments can be exchanged easily and quickly. This can be especially advantageous in case of loss of a key or malfunction of the locking device. Furthermore, it is not necessary to exchange the at least two segments at the same time; on the contrary, it is also conceivable to replace only one of the at least two segments.

In this context, it should be noted that the at least two segments may be formed symmetrically to each other according to a further embodiment. Due to the symmetrical design of the at least two segments, the production of these is substantially simplified. This results in a reduction of the production costs as well as the quality and reproducibility of the individual segments.

In the following, a preferred embodiment of the sliding window or sliding door according to the invention will be explained in more detail with reference to the accompanying drawings.

Fig. 1 shows as an exemplary embodiment of the invention, a sliding window 10 with a closing device in a schematic representation. The sliding window 10 has a frame 20, which is usually anchored in the outer wall of a building. This frame 20 encloses a through the sliding window 10 to be closed surface. In the sliding frame are two wings 30, 40, each having a window surface 31, 41, usually made of glass. The window area is surrounded by a profile frame. At least the wing 40, also referred to as "sliding wing", is mounted relative to the frame 20 vertically displaceable in the sliding direction 11. For this purpose, for example, there may be a profile on the inner peripheral edge of the window frame 20, in which the sliding window 10 is guided in the sliding direction. The other wing 30 may be firmly connected to the frame 20. Profiles of the wings arranged transversely to the sliding direction in the window frame 20 are also referred to as "transverse webs".

In the closed state of the sliding window 10 are two transverse webs 32, 42 of the profile frame of the wings 30, 40 facing each other and partially overlapping in the direction perpendicular to the area enclosed by the frame 20 surface one above the other. In this overlapping region two segments 51, 52 of the locking device 50 are mounted in a central position. However, it is also possible to arrange the segments 51, 52 of the closing device 50 non-centrally, for example in a position adjacent to the frame 20, on the transverse webs 32, 42.

Fig. 2 shows the locking device 50 and its attachment in the transverse webs 32, 42 in detail. The locking device 50 has the two segments 51, 55. The segments 51, 55 are rotationally symmetrical to an axis perpendicular to the area enclosed by the frame 20 surface at its peripheral surface. This facilitates the assembly in the transverse webs 32, 42, since only one bore in a central arrangement in the direction perpendicular to the area enclosed by the frame 20 surface by the transverse webs 32, 42 is provided. At the same time the locking device 50 is rotatably mounted in the transverse webs 32, 42 in this way.

In another embodiment, the transverse webs 32, 42 can be provided with rotatable bearings with a square opening into which, for example, a closing device 50 with a square cross-section could be inserted.

At the mutually facing ends of the segments 51, 55 are the engagement surfaces 52, 56, with which the segments 51, 55 engage each other when closing the window. At the opposite ends of the segments 51, 55 are the reinforcements 60 in the form of annular, radially extending collar. The reinforcements 60 distribute, for example, a force occurring by force, with which the transverse webs are to be spaced from each other in the direction perpendicular to the area enclosed by the frame 20 surface, on a larger contact surface between transverse webs 32, 42 and locking device 50, which is intended to absorb the force. In this way, it is possible to use an unreinforced profile for the transverse webs 32, 42, without reducing the strength of the system consisting of locking device 50 and transverse webs 32, 42.

It is possible to make the reinforcement (s) 60 integral with the segments 51, 55 of the locking device 50. The reinforcement 60 could also be screwed onto threads on the outwardly facing ends of the segments 51, 55. Alternatively, however, it is also possible to carry out the outwardly facing ends of the segments 51, 55 radially outwardly extending collars only with a slightly larger radius than the body of the segment. An additional, disc-shaped reinforcing ring could then be mounted between the collar and the transverse web 32, 42, respectively.

In the in Fig. 2 shown partial section of the window 10, this is in a closed state, so that the two segments 51, 55 are exactly opposite and the axes of rotation of both segments 51, 55 coincide. In this state, the engagement surfaces 52, 56 of the segments 51, 55 are in operative engagement.

Fig. 3 shows the engagement surfaces 52, 56 in detail. Both engagement surfaces 52, 56 are identical in the preferred embodiment. At the same time, if they like in Fig. 3 placed opposite each other, a point symmetry. However, it is also possible in alternative embodiments to form mutually complementary engagement surfaces which are not identical and do not have this symmetry.

Because of the symmetry, only the in Fig. 3 visible engagement surface 52 described. It has on the one hand at least two surfaces which are aligned perpendicular to the axis of rotation of the locking device 50 and parallel to the sliding direction 11. Between the surfaces of a labyrinth 54 is arranged, whose edges are aligned parallel to the sliding direction 11 in the open state. Furthermore, the engagement surface 52 has a stop 53. This stop 53 is perpendicular to the sliding direction 11 in the open state.

Consequently, when the closing device 50 is in an opened state, the surfaces and the edges of the labyrinth 54 can slide past one another in the sliding direction 11 when the sliding leaf 40 is closed, until the stop 53 of the segment 51 comes into contact with the corresponding stop of the segment 55.

Fig. 4 shows a state of the closure device 50, in which both the surfaces and the stops and the labyrinths 54 of the engagement surfaces 52, 56 are in surface contact with each other. At the same time, it can be seen that the labyrinths 54 are in a form-locking operative engagement by their overhanging edges and surfaces, so that forces can be transmitted over these surfaces which prevent the segments 51, 55 from pulling apart along the axis of rotation.

Also shows Fig. 4 in that the axes of rotation of the segments 51, 53 coincide when the stops are in contact with each other. This makes it possible, the entire locking device 50 by an actuating element, for example by a key 70 to rotate about the axis of rotation. If this is done and the surfaces and edges of the mazes 54 are no longer aligned parallel to the sliding direction 11, it is no longer possible to move the segments 51, 55 of the locking device 50 against each other, because a simultaneously required in this case movement component transverse to the sliding direction 11th is prevented by the frame 10. In a preferred closed position, the surfaces and edges of the labyrinth 54 are rotated transversely to the sliding direction 11 by 90 ° relative to the open position and oriented perpendicular to a force in the sliding direction 11, so that such a force can exert no transverse component or torque on the locking device 50 which could rotate and open the latch 50 to the open position.

The invention is not limited to the embodiment shown in the drawings, but results from a synopsis of the features disclosed herein.
