Description

DESCRIPTION

The present invention relates to a lift and slide structure in particular a lift and slide door or lift and slide window, according to the preamble of claim 1. A lift and slide structure comprises basically a first frame and at least a second frame. The second frame can be raised initially relative to the first frame by a lift and slide mechanism and then displaced. A carriage sits here by way of example on a track and lifts the frame. After displacement the second frame can be lowered again and is again secured against displacement. A frequent use of such lift and slide structures is by way of example so-called lift and slide doors which can comprise by way of example a wall frame and two sash frames with insulating glass panels. At least one of the sash frames can be housed in the manner outlined above in the wall frame .

Within the scope of an effective break-in safeguard it is desirable to secure the sash frame against unauthorised removal. This is normally achieved by means which are controlled by the lift and slide mechanism mentioned above. The means move out by way of example during lowering of the sash frame and thus restrict the free space between the sash frame and wall frame in the ideal scenario to 0 mm. The wall frame can thus still only be lifted unauthorised with difficulty. The documents DE 10 2004 005 170 Al, EP 1 728 956 Bl, EP 0 152 791 A2 and EP 2 141 314 A1 show known lift and slide doors or lift and slide windows. A break-in safeguard device of this kind with lift and slide structures is complicated and liable to breakdown.

The object of the present invention lies accordingly in an improved lift and slide structure, more particularly a....

According to the invention this is achieved by a lift and slide structure with the characterising features of claim 1. Since a first locking element connected to a frame and a second locking element connected to another frame are provided wherein the locking elements are set up to limit the lifting movement in the closed position of the sash frame, more particularly to a lifting travel between the first lifting position and the second lifting position, a simple cost-effective break-in safeguard device is achieved. As opposed to the known solutions no additional components are required on the lift and slide mechanism, more particularly movable components which are susceptible to breakdown. Rather an additional locking point is proposed, comprising a first and a second locking element, between the sash frame and the frame, which acts accordingly only in a closed position of the sash frame. It is further advantageous that the break-in safeguard device is configured in two parts. It can thus be installed after inserting the sash frame.

Further advantageous configurations of the invention are apparent more particularly from the features of the dependent claims. The features of the claims can fundamentally be combined in any way with one another.

In an advantageous configuration of the invention it can be proposed that the locking elements are configured so as not to limit the lifting movement in a non-closed displacing position. Insofar as the sash frame is located by way of example in an opened displacing position it may be concluded that lifting out the sash frame is to be possible, by way of example for maintenance purposes. It may also be concluded that the break-in safeguard device is rather troublesome for inserting the sash frame so that the break-in safeguard device is then correspondingly only to act when it is also actually required, such as when the sash frame is located in a correspondingly closed displacing position.

In a further advantageous configuration of the invention it can be proposed that the first locking element has a profile, preferably a hollow profile, which is hollow at least in certain sections, with a cutout which is open on one side, in particular with an oblong hole which is open on one side, wherein the second locking element has a shaft with at least two portions wherein the first portion has a smaller radial extent than the second portion. A configuration of the locking elements in this way can be produced economically and extremely sturdily. The so-called mushroom head which arises from the configuration of the shaft is moved into the hollow profile in the closed position of the sash frame and surrounds the mushroom head like a cage. Thus the sash frame can still only be lifted over the length of the shaft and moved towards the opened end of the oblong hole. Both degrees of freedom of movement are required for the functioning of the lift and slide mechanism. Other movements, more particularly a lifting movement beyond the length of the shaft, are however deliberately stopped, whereby the sash frame cannot be levered out in this closed position.

In a further advantageous configuration of the invention it can be proposed that the cutout has a first portion and a second portion, wherein the first portion facing towards the opening has a greater width than the second portion, wherein the first portion preferably has a V-shaped configuration. Through the configuration of the cutout, more particularly the V-shaped configuration, a type of run-in aid is produced with which for example tolerances can be compensated for the position of the locking elements.

In a further advantageous configuration of the invention it can be proposed that the frame has at least one insulating profile wherein one of the locking elements, preferably the first locking element, is connected to the insulating profile. Through this measure it can be ensured by way of example that the locking element, more particularly the first locking element, does not collide with the carriage.

In a further advantageous configuration of the invention it can be proposed that one locking element, preferably the second locking element, is attached to the foot of the sash frame in the panel joint. Since the panel is always secured on the frame side by means of locks, lifting out the panel is not possible here. The weak point of a lift and slide structure is always the region in the panel joint, i.e. in the transition between the first frame and the second frame which lies behind.

Further features and advantages of the present invention will become apparent from the following description of preferred exemplary embodiments with reference to the accompanying drawings. In the drawings:

The following reference numerals are used in the drawings: 1 Frame 2 Sash frame 3 Third frame (sash frame) 4 First locking element 5 Second locking element 6 Connecting plate 7 Insulating profile 8 Track rail 41 Hollow profile 42 Connecting means 43 Cutout/oblong hole 431 First portion 432 Second portion 51 Shaft 52 Connecting means 511 First portion 512 Second portion

Reference is initially made to Fig. 1 A lift and slide structure according to the invention comprises essentially a first frame, a second frame, where applicable a third frame, a lift and slide mechanism (not shown except for the track rails 8) and a break-in safeguard device .

In a configuration of the lift and slide structure of this kind a lift and slide door is produced by way of example as shown in Fig. 1. Further types of use are also conceivable such as by way of example a lift and slide window etc. The following is based by way of example on a lift and slide door.

The first frame is configured by way of example as a wall frame 1 and is connected in a conventional installation situation fixedly to a building (not shown). The second frame is configured by way of example as a sash frame 2 with a flat surface element, by way of example an insulating glass panel from which ultimately a sash door is produced.

The sash frame 2 is received in optionally displaceable or non-displaceable manner inside the wall frame 1. In order to enable or prevent displacement there is a lift and slide mechanism provided. This lift and slide mechanism is mostly controlled by a handle or lever (not shown) on the sash frame 2. In a first position of the lift and slide mechanism the sash frame 2 is housed immovably in the frame 1. Transferred to a lift and slide door this corresponds by way of example to a closed sash door. In a second position the sash frame 2 is lifted by the lift and slide mechanism and is set on rollers which can run in turn on track rails 8 of the frame 1. This is as a rule brought about by actuating the handle or lever. The sash frame 2 can now be displaced inside the frame 1. The sash frame 2 can again be fixed at any position of the frame 1. For this the handle or lever is again turned round and the sash frame 2 is lowered correspondingly. Transferred to a lift and slide door this corresponds by way of example to an opened or partially opened sash door. The finer details of a lift and slide mechanism are sufficiently known to one skilled in the art so that further details need not be provided at this point. A third frame 3, by way of example a sash frame with a flat surface element, by way of example an insulating glass panel, can further be provided which can be connected fixedly, but also movably, to the frame 1.

For the break-in safeguard device it is advantageous if the sash frame 2 cannot be raised unauthorised opposite the wall frame 1, or at least not raised so far that the sash frame 2 can be lifted out and removed from the frame 1. The break-in safeguard device according to the invention can be used for this. It basically comprises a first locking element 4 and a second locking element 5.

The first locking element 4 can be configured by way of example as a profile 41, more particularly a hollow profile, which is hollow in at least some sections and has an oblong hole 43 which is open on one side, and a connecting means 42. Assuming a hollow profile 41 of rectangular cross-section by way of example, the cutout 43 can be arranged by way of example in one side face and the connecting means 42 can be arranged on or in the opposite side face.

The cutout 43 can be opened on one side and has a first portion 431 and a second portion 432. The first portion 431 facing the opening then has a greater width than the second portion 432. The first portion 431 can preferably have a ν'-shaped configuration. The connecting means 42 serve to connect with the respective frame and can be configured by way of example as one side of the hollow profile 41, more particularly with bores and/or plug means. It is also possible however to provide a separate connecting plate 6 to fasten the locking element 4. Fastening the first locking element 4 is preferably onto an insulating profile 7 of the frame 1.

The second locking element 5 can be configured by way of example as a so-called mushroom head. A second locking element 5 basically comprises a connecting means 52 and a shaft 51 with two portions in the longitudinal direction. The first portion 511 facing the connecting means has a smaller diameter or a smaller radial extension that the second portion 512. The shaft 51 can be equipped by way of example with a thread and can be screwed into the connecting means 52. The connecting means 52 can be configured by way of example as a block, more particularly as a plastics block. Fig. 6 shows in an exploded view the break-in safeguard device for a lift and slide structure according to the invention.

Further details of the break-in safeguard device are apparent from a description of the functioning of the lift and slide structure according to the invention.

The first locking element 4 is preferably fastened on the frame 1. The second locking element 5 is preferably fastened on the sash frame 2. A vice-versa arrangement is also conceivable .

The sash frame 2 can occupy at least four positions in relation to the frame 1. On the one hand the first displacing position already mentioned above and second displacing position, which adopting a Cartesian coordinate system corresponds to a first X-position and a second X-position and in terms of function represents a closed and an opened position of the lift and slide door or sash frame 2. The sash frame 2 can furthermore occupy in relation to the frame 1 a first lifting position and a second lifting position which correspond to a first Y-position and a second Y-position.

Fig. 2 shows the sash frame 2 in the first displacing position and the first lifting position. This corresponds to the state of a closed and lowered sash frame 2. The second portion 512 of the second locking element 5, say the mushroom head, is received in the first locking element 4.

Fig. 3 shows the sash frame 2 in the first displacing position and the second lifting position. This corresponds to the state of a closed, but raised sash frame 2. The second portion 512 of the second locking element 5 is received in the first locking element 4. The second portion 512, say the mushroom head, is displaced upwards about the lifting movement, but does not yet or only just abuts the upper side of the first locking element 4. The second portion 512 does not pass through the cutout 41, more particularly not through the second portion 432 of the cutout 43. The maximum lifting travel between the first lifting position and second lifting position is determined correspondingly by the length of the first portion 511 of the shaft 51 of the second locking element 5.

Fig. 4 shows the sash frame 2 in the second displacing position and the second lifting position. This corresponds to the state of an opened but not yet lifted sash frame 2. The second portion 512 of the second locking element 5, say the mushroom head, is no longer received in the first locking element 4.

Fig. 5 shows the sash frame 2 in the second displacing position and the first lifting position. This corresponds to the state of an opened and now lowered sash frame 2. The second portion 512 of the second locking element 5, say the mushroom head, is no longer received in the first locking element 4.

Closing the door and returning the sash frame 2 into its first displacing position and first lifting position is achieved in the correspondingly reversed sequence of the aforementioned steps. The positions indicated above are not conclusive. Obviously intermediate positions are conceivable.

The functioning of the break-in safeguard device is achieved essentially from Figs. 2 and 3 and the positioning of the locking elements 4, 5 illustrated therein. It is apparent that the sash frame 2 can indeed be raised by roughly the length of the first portion 511 of the second locking element 5, but no further and therefore not be lifted out from the frame 1. This provides an effective commercially viable break-in safeguard since the sash frame 2 cannot be lifted unauthorised out from the frame 1.
