Description

Device for covering a sliding sash or sliding lifting / sliding sash of a window or a door

The invention relates to a device for covering a movable in a collision area on a running rail first casement as sliding or sliding sliding sliding wing of a window or a door according to the preamble of claim 1.

Sliding wings as sliding sash or sliding lift-sliding sash of a window or a door are known in various designs and consist in the simplest case of a slidably arranged in an outer frame for opening and closing wings arranged as sliding sash and from a, also arranged in the frame further door or a window element, such as fixed leaf or fixed field.

The closed sliding sash can be locked on its side facing away from the door or window element by pressing a fitting provided in the sash frame on the frame and thus secured against unauthorized opening. Horizontally movable sliding sashes are usually slidably received above or below the sliding sash. When opening, usually with an operating handle lift-slide wings, the sliding sash is raised with the seals, making it easier to run. The opened sliding sash can then be pushed in front of an adjacent inactive leaf. Depending on the version, lift and slide sashes can only be pushed or tilted additionally. When closing the sliding sash is lowered and thus the seals pressed again. The opening and closing is also via electrical, hydraulic or pneumatic

Actuators possible.

A seal in the vertical transition or impact area between sliding sash and fixed field, where the closed sliding sash connects to the other fixed field or door or window element, is generally carried out by means sealing in the closed position sealing or profile strips with seals.

In this joint area sealing or molding strips are known, which are attached to a vertical portion of the sash and the other door or window element, so that when the sliding sash closed the sealing strips overlap in the region of their first profile sections and at the same time reach behind. The closing of gaps between sliding leaf and passive leaf in the vertical area of the sealing strips takes place with regard to measures for Tightness against possible ingress of water due to high wind loads and

Driving rain stress due to lip seals. For closing gaps of a receiving groove also in the joint area at the top and bottom of the vertical

Wing spar of the sliding wing, caused by the inclusion of hardware components, however, is neglected in terms of the prior art, the appearance and assembly. For covering cover elements are used, due to the

Strongly build up the material thickness on the wing spar. Reason for the strong construction of material include the countersunk holes for a Schraubbefestigung the cover to the wing spar of the sliding sash. Consequently, a screw fastening proves to be an optical disadvantage, since the screws, in particular the screw heads, are clearly visible on the wing spar. Furthermore, the cover elements are suitably shaped, but not adapted adapted to today's design trend. In addition, the cover is rigidly screwed in a screw fastening. An assembly and a release of the cover over the fasteners by screwing proves to be expensive and expensive.

Such lift-and-slide wings are known in the art.

DE 20 2008 001 251 U1 discloses a lifting-sliding wing according to the preamble of claim 1.

In this case, a lift-slide door has become known with a lift-slide wing, which is slidably guided with a carriage included in a lower frame part of the sash of the lift-slide wing on a running rail which is mounted on a lower frame part of a frame frame, wherein when the lift-sliding sash is closed in a joint area between the lift-slide sash and a side frame part of the frame, a cover element is provided which is fixed in the joint area on the sash and over which the lift-slide sash in the lowered state rests on the running rail, wherein the cover a base and a fastening part is constructed, wherein the base in the lower region has a recess corresponding to the contour of

Carriage rail is complementary and in which receives a portion of the carriage rail in the lowered state of the lifting sliding sash.

The invention has for its object to provide a functionally reliable and compact device for covering a sliding wing as sliding sash or sliding lift-sliding sash of a window or door, which overcomes the above disadvantages and good optics for the window or the door is inexpensive and can be mounted in a simple, fast, safe and precise manner with little space and adjusted. To solve this problem, a sliding sash or lifting-sliding sash of a window or a door on a covering, which consists of a cover and a

Fixing device consists, which is thin-walled formed on an end face of a vertical wing spar of the sliding leaf.

For this purpose, the cover is preferably arranged with an open sliding sash between an end face of a vertical wing spar of the sash and a laterally vertical Blendrahmenholm of the frame on the sliding sash, which means of

Fixing device on the sliding sash allows a fixed position. The flat surface adapted to the flat surface of the end face of the wing spar or the entire window or the door, the cover member has a cover plate with a flat surface, which on a flat side facing the end face of the vertical wing spar facing the visible

Outside concealed lying a connecting means of the fastening device, which is operatively connected to a mounted on the sliding sash attachment part of the fastening device positively and / or non-positively releasably and also concealed by the cover plate mounted. Furthermore covers the cover plate, the recorded on the upper wing spar in a receiving groove fitting elements and recorded on the lower wing spar in a receiving groove carriage of the sliding wing, due to the low

Material thickness of <2 mm, almost flush with the face of the vertical wing spar.

Preferably, the cover plate and the connecting means are integrally formed. The cover plate extends to an outside over the entire surface visibly resting on the end face of the vertical wing spar of the sliding leaf, the connecting means of the cover completely hidden covered in the receiving groove of the sliding leaf and finally is operatively connected in engagement with the fastening part. The one-piece design of the cover with the connecting means can achieve a secure fit.

In addition, apart from an additional expense in the assembly by other attachments.

Such a covering device ensures a market-oriented visual appearance with the cover plate in the basic form as a cuboid and in a material thickness of <2 mm. The angular design of the cover in adaptation to visible attachments,

for example, to an operating lever and to the window or the door itself, gives the window or door the overall impression of a clear seamless design and completes a design trend.

Particularly advantageous in the manufacture and in the assembly to the window or the door is that the cover device can be mounted with rotation of the cover member about its own axis both to the upper receiving groove and to the lower receiving groove of the sliding leaf is. Even the fastening device, consisting of the connecting means on

Covering element and attached as an attachment to the sliding panel mounting part are formed consistent.

With the formation of a sleeve as a fastening part, which is functionally and visually equivalent to a dowel and the connecting means of the cover as a jack, results in simple means a detachable plug or clip connection of the fastening device. The connecting parts are aligned by positive fit of the connector parts and fixed by spring force non-positively releasably. Easy to handle and quick to install, the sleeve is placed in a prefabricated bore of the vertical wing spar of the

Sliding wing introduced or smashed. In order to achieve a solid permanent seat of the sleeve in the bore, a corrugation or a knurl is incorporated on the outer shell of the sleeve at least for a portion.

Likewise, for fixing a magnetic solution or another variant of a

Clip connection conceivable. The solution according to the invention stands out from the known embodiments that, with a secure hold, there is also an easy-to-produce and cost-effective design, which is also easy to handle.
