Description

The invention relates to a fitting for a sliding leaf of a door, a window or the like.

A fitting of the type mentioned is known. It is inserted with its housing in an opening of the sliding leaf, wherein a fastening member is placed in a rear handle to the inner edge of the opening and the other fastening member is displaced against the spring force when pressing the fitting into the opening and springs back in the fully inserted state, also a rear handle to create the corresponding inner edge of the opening. In the mounted state, the cover plate lies with its rear side on the associated side of the sliding leaf, thereby covering the opening. For disassembly of the known fitting, it is necessary to lever the cover plate by means of a suitable tool to overcome the spring force of the elastic fastening member. From all this it is clear that the fitting can be removed by simple, prudent levering back the opening so that security requirements are not met with regard to the locking of the sliding sash.

From the EP-A-1 039 070 a fitting for a sliding leaf is known, which is inserted into an opening of the sliding leaf and can be fixed by means of rotary bolts or spring-loaded sliding latch.

The invention is therefore an object of the invention to provide a fitting of the type mentioned above, which is securely fixed to the sliding sash with a simple design and ease of assembly and thus meets normal safety requirements, even those that are specified by insurance.

This object is achieved in a fitting for a sliding leaf of a door, a window or the like in that a housing and that two fastening members are provided, wherein the fastening members are located on opposite sides of the housing and together with the housing in an opening of the Sliding wings are used and each having means which come into engagement with the associated inner edge of the opening, and with a cover plate associated with the housing, which can be applied to one side of the sliding leaf and thereby covers the opening, wherein at least one of the fastening elements as one of the Rear side of the fitting ago manually operable, displaceable in a blocking position or unlock position rear handle element is formed, the rear handle element is a sliding latch, wherein at least one screw acts on the sliding bolt for bolt displacement and derar the longitudinal axis of the screw t obliquely inclined to the longitudinal extent of the housing extends, that its front end is closer to the cover plate than its rear, an actuating end forming end. Due to the possible only from the back of the locking fitting her operability of the movable rear handle element results in a high level of security, as from the front of the fitting ago no accessibility to remove or open the fitting. The fitting looks visually appealing, since the front has no visible fastener. Since the cover plate the opening in the sliding sash there is no possibility to gain access to the fitting from the visible side, so that optical and safety requirements are met. When installing the fitting, the housing is first introduced with the two fastening members from the front of the sliding leaf forth in the opening of the sliding sash. Preferably, one of the fastening elements is designed as a rigid rear grip element and arranged stationary. This is brought to the inner edge of the opening when inserted into the rear grip position. Subsequently, the other fastening member is manually displaced from the rear side of the sliding leaf and thereby brought into the locking position, in which there is a rear grip to the corresponding inner edge of the opening. In the assembled state, the cover plate of the fitting is supported on the front side of the sliding sash. The accessibility to the rear of the fitting is given by the fact that the sliding sash usually has a through opening, that is, it extends from the front of the sash to the back, so that the back of the fitting is achieved by lying on the back of the opening area. The rear grip element is a sliding latch. This is operated by the back of the fitting and can thus be spent in the locked position or unlock position. The blocking position is secured by means of a suitable securing element from the rear side, so that the sliding bolt can not be moved unintentionally to its unlocked position. It is envisaged that at least one screw acts on the sliding latch for latch displacement. The screw thus forms an actuating element and the above-mentioned securing element. Accordingly, there are two elements, namely the screw, which is preferably only one screw Alternatively, however, may also be provided a plurality of screws, and the sliding bolt, wherein the sliding bolt is displaced by actuation of the screw, so that it makes or reverses the rear handle to the inner edge of the opening. It is inventively provided that the longitudinal axis of the screw extends obliquely inclined to the longitudinal extent of the housing, that its front end is closer to the cover plate than its rear, an actuating end forming end. It is further provided that the longitudinal axis of the screw encloses an angle α with the longitudinal extent of the longitudinal guide of the sliding latch. Accordingly, the slide bar is biased by the screw. This has the advantage that the sliding bolt can be displaced in the longitudinal extent of the housing and thereby has a positive connection to the opening edge in the blocking position, wherein the obliquely extending screw is more accessible due to the inclination, since a screwdriver does not have to be fed in the longitudinal direction, but in an inclined position, that is, in a direction pointing from the back to the front of the sliding sash and accordingly obliquely through the opening passing through the sliding sash. The mentioned angle α is preferably an acute angle.

The screw can be designed in particular as a grub screw. It is preferably screwed into a threaded bore of the housing, wherein the threaded bore extends in such a way that by deeper screwing the screw their front end causes the locking position and that loosening the screw, without that it must be unscrewed completely out of the threaded hole, that the front end of the screw assumes a position which leads to the unlocking of the fitting.

Preferably, the fitting is associated with a sliding leaf of a door, a window or the like, wherein the airfoil as a hollow profile, for example, plastic hollow profile or aluminum profile is formed, wherein opposing Hohlprofilwandungen each having an opening for forming the opening on the front and to form the on having the rear side opening. In the rebate area, the profile optionally has a further opening to install a bolt there.

In particular, the sliding latch is displaceably mounted in a longitudinal guide of the housing. The longitudinal guide preferably extends in the direction of the longitudinal extension of the housing. This longitudinal extent coincides with the longitudinal extent of the cover plate. In the installed state of the fitting in a vertical rail of a sliding door or the like, the longitudinal extent extends in the vertical direction.

It is advantageous if the longitudinal axis of the screw crosses or intersects the longitudinal axis of the housing. In the case of crossing, the two axes form an angle <180 ° to each other, but do not intersect, and in the case of cutting both axes are such that they lie at the intersection in the same plane and therefore meet.

As already mentioned, the other attachment member may be a rigid Hintergrifforgan that can not be relocated. Alternatively, it is of course also possible that both fastening organs manually are operable to relocate them in a locked position or unlocked position from the back of the fitting ago.

The housing preferably has a recessed grip, so that the fitting can be referred to as a handle fitting. It is possible to provide him with a bolt or even make a design that has no latch.

In particular, it can be provided that a bearing block arrangement for the screw and the sliding bolt are formed adjacent to the recessed grip.

As already explained, it is provided that the rear grip element is arranged in such a way that it is accessible from the opening area facing the rear side of the fitting through the opening passing through the sliding wing.

The invention further relates to a fitting system with a fitting, in particular handle fitting, which - as described above - is formed, wherein it is insertable into one end of the sliding wing passing through opening. Further, the fitting system has a lock fitting for insertion into the other end of the opening, the lock fitting having a lock fitting housing and a latch for locking the sliding leaf, and wherein two lock fitting fasteners are disposed on opposite sides of the lock fitting housing and into the other together with the lock fitting housing End of the opening of the sliding leaf can be used and each having means that come into engagement with the associated inner edge of the opening. Here is a the locking fitting housing associated locking fitting cover plate provided, which can be applied to the associated side of the sliding leaf while covering the corresponding end of the opening, wherein at least one of the Verriegelungsbeschlagsbefestigungsorgane stored and / or is such that it can yield elastically in the direction of the center of the housing. The fitting system is therefore on the one hand to a fitting which is installed in one end of the opening of the sliding leaf and has on its back a displaceable in blocking position or unlocking rear engagement element. This fitting is installed first because its backside is accessible from the other end of the opening passing through the sliding panel only as long as there is nothing installed in the other end of the opening. By accessibility, the rear handle element can be spent in the locked position. The fitting can not be removed from the front of the sliding sash. Then the locking fitting is installed on the back of the sliding sash in the area of the opening located there. This is done by overcoming the restoring force of the elastically evasive locking fitting attachment member, preferably only one locking fitting attachment member is elastic and the other rigid. Of course, it can also be provided that both locking fitting fixing members are elastically displaceable by spring force or the like or even have an inherent elasticity. Then the bolt is installed. This is introduced into a rabbet opening of the sliding leaf and fastened from the outside of the locking fitting. For this purpose, the locking fitting on a corresponding exposable opening, for example, to be able to introduce a screwdriver, with a fixing screw a bolt receptacle can be tightened, whereby the bolt is fixed. The fitting, which is provided with a manually manipulatable rear grip element only from its rear side, is assigned in particular to the outside of a sliding leaf of a door, a window or the like, while the locking fitting is assigned to the inside. In order to disassemble the locking fitting, it is only necessary to lever it out of the opening, whereby the restoring force of the corresponding locking fitting fastening member is overcome by its elastic deflection.

Furthermore, the invention relates to a sliding leaf of a door, a window or the like with a fitting or fitting system, each in an embodiment as described above.

The FIG. 1 shows a fitting 1, which is designed as a handle fitting 2, that is, it represents a handle with which the sliding sash can be opened and closed. In the following, the handle fitting 2 is discussed in more detail. According to another embodiment, not shown, the fitting 1 may also be designed as a locking fitting, that is, it not only has an opportunity to attack, but also an element to actuate a bolt with which the sliding sash can be locked.

The fitting 1 of FIGS. 1 to 6 has a housing 3 which lies on its rear side 4. The front side 5 of the fitting 1 is essentially embossed by a cover plate 6, which rests flat in the installed state on the front of a sliding panel not shown and covering an opening of the sliding leaf, in which the fitting 1 is installed with its housing 3.

The housing 3 includes a recessed grip 7, which is accessible from the front side 5 ago. In longitudinal extension (double arrow 8) of the housing 3 and the fitting 1 ( FIG. 3 ) is disposed adjacent to the rear recessed grip 7 and adjacent to the housing 3, a first fastening member 9. On the opposite side of the housing 3 is a second fastening member 10. The two fastening members 9, 10 have a clamping distance 11 from each other. Both attachment organs 9 and 10 are located on the back 4 of the fitting 1 and are accessible only from the back 4, when the fitting 1 is installed in an opening of a sliding sash. The first fastening member 9 is associated with a bearing block assembly 12, which has a pointing away from the back 4 bearing projection 13 and a bolt guide 14. The bearing projection 13 is located between the bolt guide 14 and the recessed grip 7 (FIG. FIG. 3 ). The bearing block assembly 12, according to the FIG. 5 in its bearing projection 13, a threaded bore 15, the longitudinal axis 16 with the longitudinal extent 17 of the bolt guide 14 forms an angle α of 30 °. The longitudinal extent 17 corresponds to the direction of the double arrow 8. The bolt guide 14 forms a longitudinal guide 17, which allows a straight-line displacement of a sliding bolt 19. The sliding bolt 19 is in perspective view in the FIG. 6 shown. The FIG. 5 shows the bearing block assembly 12 without insertable sliding bolt 19. In the threaded bore 15 of the bearing block assembly 12 is - according to FIG. 3 - Screwed a screw 20, which is designed as a threaded screw, preferably as a grub screw 21. Preferably, only a single screw 20 is provided with the - according to FIG. 3 - The sliding bolt 19 can be acted upon to its displacement along the longitudinal guide 18. In the FIG. 5 the bearing block assembly 12 is shown without grub screw 21. The bearing projection 13 has an upper side 22 'which encloses an obtuse angle β with the plane of the cover plate 6 of 120 ° ( FIG. 5 ).

The sliding bolt 19 has - according to FIG. 6 - A locking body 22 which has a locking lug 23 on its front side. To the locking lug 23 opposite are located on the bolt body two Side projections 24, which protrude from the sides 25 of the latch body 22.

The bolt guide 14 has a guide channel 26 which is open to the lower end 27 of the longitudinal guide 18. Further, the guide channel 26 is accessible from above by means of an access slot 28 which lies between the bottom 29 of the bearing projection 13 and the front end of a front wall 30 of the longitudinal guide 18. Through the access slot 28, the sliding bolt 19 can be inserted into the bolt guide 14.

The second fastening member 10 has a rigid, stationary, in the outwardly facing direction of the double arrow 8 oriented rear grip projection 31, so that between the back of the cover plate 6 and the rear handle projection 31, a receiving pocket 32 is formed. Furthermore, a receiving pocket 33 is formed between the locking lug 23 of the fastening element 9 and the rear side of the cover plate 6 ( FIG. 3 ).

According to FIG. 3 is the sliding bolt 19 in the bolt guide 14, such that it along the guide channel 26 in the direction of the double arrow 8, ie in the longitudinal extent of the housing 4 or longitudinal extent of the fitting 1, is displaced. As a result, he can assume a blocking position or an unlocked position. The displacement takes place by means of screwed into the threaded hole 15 screw 20, in particular grub screw 21. In the delivered condition of the fitting 1, the grub screw 21 is only so deep screwed into the threaded hole 15, that the locking lug 23 does not or only slightly protrudes from the bolt guide 14 ,

This results in the following function: It is assumed that the fitting 1 is to be installed in an opening 34 of a sliding leaf 35 of a sliding door or the like ( FIG. 3 ). Of the sliding wing 35 having hollow sections, only a front hollow profile wall 36 is shown having the opening 34, wherein the opening 34 extends through the entire hollow profile, that extends to the back of the sliding leaf 35, so that the opening 34 has a through opening 34, wherein the fitting 1 is now to be installed in the one end of the opening 34. For this purpose, the fitter pushes the fitting 1 with its housing 3 and the two fastening members 9 and 10 in the opening 34, so that the back of the cover plate 6 flat on the front of the hollow profile wall 36 sets. The upper edge of the opening 34 is engaged behind by the rear grip projection 31 of the fastening member 10. Now the fitter takes a screwdriver and leads him from the other end of the opening 34, ie from the back of the sliding leaf 35 forth, the back 4 of the fitting 1 and thus rotates the grub screw 21 deeper into the bearing projection 13 so that its front end 37th placed on the top 38 of the latch body 22 and thereby the sliding latch 19 displaced in the outwardly facing direction of the double arrow 8, so that the locking lug 23 so far exits the latch guide 14, that the inner edge of the opening 34 is engaged behind by the locking lug 23. The corresponding edge region of the opening 34 is therefore in the receiving pocket 33, so that the fitting 1 is fixed from the back 4 ago and can not be dismantled from the front 5. Disassembly is only possible in turn only from the back 4 ago, namely by loosening the grub screw 21, whereby the sliding bolt 19 recede accordingly can and removal of the fitting 1 from the opening 34 is possible.

From all of this it is clear that the fitting 1, which can be used as an outer fitting, that is on the outside of doors, windows and the like, is not removable from the outside, so that the relevant safety requirements are met. Since it is preferably fixed only with a single screw, which is operable only from the inside, wherein the screw forms a fastener or together with a sliding latch forms a fastener, a very simple structure with only a few parts is given. At the same time there is an aesthetic design, since no fastener is visible from the front of the fitting.
