The shelf comprises a plate guided in a frame on a beam (13). When secured, it interacts with a lift stop (14). The shelf can have a closed slide slit (15) which determines the path of movement between the secure position and rest position. The projection can engage in a forked recess (18) in the bearing part.

Description

The invention relates to a fitting for doors or window, with a fuse that can be attached in the rebate area Securing the door or window sash against lifting, which is a locking tab has that with a closed part with a bearing part is in backup engagement.

A fitting with the aforementioned features is from the DE-A-29 29 382 known. The locking tab is an angled Cuff rail edge, which when closing the wing grips under the bearing part, which is firmly attached to the frame struck striker sits. In an attempt to When the sash is lifted out, the securing projection hits the bearing part and the wing is prevented from being lifted out. Indeed it is necessary that the well-known safety projection and the known bearing part does not interact in a tight fit. Otherwise you could get the one you want with this fitting Disrupt the toggle lock function. The security intervention is therefore such that manipulations on the wing to the extent of Play between the locking tab and the bearing part possible are.

The invention is therefore based on the object of the security intervention to improve that in the event of a backup the least tolerance-tolerant intervention of the safety projection and can produce bearing part.

This object is achieved in that the bearing part when closing the wing with the safety projection in the Secure position is shifted and this when opening the Leaves automatically.

For the invention, the use of a mobile Bearing part in the area of anti-lift protection of importance. With With the help of this movable bearing part, a very precise, low-tolerance engagement between the securing projection and reach the bearing part, so that the securing position both are precisely defined accordingly. Other fittings cannot influence the safety position take or the fitting can also be completely independent of about further existing fittings of the door or window sash be used. It is therefore also advantageous for Suitable for retrofitting, so it can also be used on older windows a reliable in the context of its strength and attachment To secure against lifting. The one for the function the required mobility of the bearing part reach themselves with simple means so that the fitting also constructively with comparatively little effort is.

To simplify the design of the fitting, the fitting is designed so that the bearing part a plate guided in the rebate on a frame spar which cooperates with a lifting stop in the securing position. Such a plate is in all directions Plate level is sufficiently stable and has the appropriate training sufficient strength values also perpendicular to the board plane on. It is to be mass-produced, e.g. by punching, and can adhere to the shape the lifting stop can be adjusted in a simple manner.

It is advantageous to design the fitting so that the Bearing part has a closed slot that the Path of movement between the safe position and the rest position of the bearing part determined. With the help of the backdrop slot the bearing part must be fastened captively. The The shape of the slot allows the movement path to be adjusted of the bearing part in different positions of the Locking tab and the lifting stop.

The fitting can be designed so that it is a Has collar screw, on the collar of the bearing part with the slot slot is led. This will guide the bearing part improved on the collar screw.

Another improvement in the management of the bearing part can be achieved in that the fitting is designed is that it influences the path of movement of the bearing part Has guide bar.

A design of the fitting in the sense of an expedient Design of the form fit between the safety projection and bearing part is achieved in that the bearing part has a fork-like recess into which the securing projection retracts when closing the wing. The fork-like Recess of the bearing part clings to the securing projection, which can be supported on the bearing part during lifting attempts.

A further improvement of the form fit in the security intervention results from the fact that the bearing part the lifting stop in the locked position with another fork-like Clasped recess. Since the lifting stop and the securing projection is spaced apart are, the bearing part at two points apart positively applied and thereby achieves a corresponding Security against lifting in opposite directions Directions.

The security against lifting is further increased by that the safety projection and / or the lifting stop are mushroom-shaped, the mushroom head the Bearing part overlaps. As a result, it is not possible Wing in the longitudinal direction of the securing projection and / or the Lifting stroke to lift because their mushroom heads the bearing part hold down accordingly.

As a further development of the fitting, it can be equipped in this way be that the bearing part has a fixed axis for a Closing of the wing sliding swivel movement having. With the help of the fixed axis, the sliding swivel movement can of the bearing part to coordinate well that the wing moves perpendicular to the frame plane performs a while to achieve the securing position both across and in the latter frame level Movement of the bearing part carried out at frame level must become. The fixed axis avoids further movement of the bearing part serving guide elements and serves in the securing position of a securing device against lifting.

An education that is narrow perpendicular to the frame level of the fitting is achieved in that the securing projection, the bearing part with its fixed axis and the lifting stop with the sash closed one in the longitudinal direction of the bar Take up stretched position. The stretched position is in particular also favorable in the sense of securing against lifting in the longitudinal direction of the bar.

To the fitting in the sense of securing against lifting advantageous to train across the frame level, it is useful if the fixed axis of the bearing part when closed Wing approximately in the middle between the safety projection and the Lifting stop is arranged. When lifting attempts across Frame level, the fixed axis can be a large part of the removed Take on the load and the safety lead and the Lifting stop are in due to the same sized lever arms loaded to the same extent, so that an even load distribution takes place, which is in the sense of an optimal backup.

In particular, against lifting attempts across the frame level it is advantageous to design the fitting so that the bearing part one the guide bar and / or another holding projection has engaging retaining hooks. The retaining hook holds the bearing part on the guide rail or on one other retaining projection and can also be secured in Serve longitudinal bar direction.

The fitting can be designed so that the lifting stop fixed on the bearing part side or on the safety projection side is. If the lifting stop is attached to the bearing part, So fixed when the bearing part on the fixed Frame is struck, an anti-lift device is installed due to the effect of the lifting stroke especially in Direction of the frame spar. If the lifting stop is on the safety projection side attached when fastening the bearing part the lifting stop acts on the window frame on the casement only against lifting to frame level, if the bearing part is not otherwise prevented from being lifted in the direction of the frame rail is supported.

1 to 3 corresponding representations with a different design of the fitting parts. 1 and 4 show views of the end faces of the casement.

On the wing 10 shown in Figure 1 is a fitting part 22 attached, for example with not shown, through mounting holes 23 in the wing 10 or fastening screws screwed into its casement. The fitting plate is provided with a locking projection 11, the in the rebate space between the wing and the fixed Frame protrudes. This head start 11 is integral with the fitting part 22 and, for example made by injection molding. The locking tab 11 is mushroom-shaped, so it has a mushroom head.

On the fixed frame, only a section of which of a vertical frame spar 13 is shown in the area of the rebate, a support plate 25 is attached, for example, not shown, through the mounting holes 23 screwed fastening screws. The mounting plate 25 is used to support a bearing part 12, which is designed as a plate. The bearing part 12 is therefore flat and can therefore be manufactured as a stamped part. The bearing part 12 is limited to the support plate 25 sliding swivel. It has a slot slot 15, through which a collar screw 16 into the support plate 25 is screwed in, which is designed as a cylinder section Bund the leadership of the bearing part 12 through the slot slot causes, the head of the collar screw of the holder of the Bearing part 12 on the support plate 25 is used without the mobility to affect the bearing part 12. The collar screw 16 forms a fixed axis 20 for the bearing part 12, which itself in when the wing 10 is open due to its gravity the position shown in Fig.2.

The bearing part is fork-like at its lower end Recess 18 provided on the design the locking projection 11 is coordinated. The fork ends limit a part-circular concave contour with the Radius of the locking projection 11. At the opposite end of the bearing part 12 there is a fork-like recess 19, which can cooperate with a lifting stop 14. The lifting stop 14 is attached to the support plate 25 and trained in the same way as the locking projection 11. Accordingly, the fork-like recess 19 with provided a part-circular contour on the lifting stop 14 is matched.

The arrangement of the locking projection 11, the fixed Axis 20 or the collar screw 16 and the lifting stop 14 is such that all three elements are with the wing closed 10 are in the extended position, namely or preferably on one aligned line in the longitudinal direction of the frame spar 13. In this arrangement shown in Figure 3 is the Bearing part in an orientation that is parallel to the frame spar 13 runs. So that the required sliding swivel movement not exclusively with the cooperation of the collar screw 16 and the bearing part 12 takes place, the support plate 25 with a Guide bar 17 provided vertically from the support plate 25 protrudes into the rebate space, the protrusion approximately the thickness of the bearing part 12 designed as a plate corresponds. As a result, the bearing part 12 at its Movement from the rest position in Fig.2 in its safety engagement 3 are guided by the guide bar 17. For this purpose, the guide bar 17 is in relation to the bearing part 12 concave and their curvature corresponds to the curvature the corresponding outer circumference of the bearing part 12.

At the lower end of the bearing part 12 in FIG Retaining hook 21 is provided, which cooperate with the guide bar 17 can. The retaining hook 21 encompasses that in Fig.3 lower end of the guide bar 17 when the bearing part 12 in Security intervention has been postponed. He then saves against Lift the wing across the spar in the display plane 13.

4 to 6 differs in the fitting Design between the fitting part 22 and the support plate 25 by the arrangement of the lifting stop 14. This is on attached to the fitting part 22 and jumps parallel to the locking projection 11 before. As a result, he has no powers to transfer to the frame spar 13, however, serves to secure the position of the bearing part 12 when this engages in the fuse is adjusted and thus supports the wing Lift off across the frame level.

The fitting works as follows: With the window sash open the bearing part 12 is arranged according to FIG. 2 or 5. As a result its gravity hangs within the slot 15 on the collar screw 16 and is based on the Guide bar 17 from. Spring force support is possible. If the wing 10 is closed, the locking projection runs 11 according to arrow 26 in the fork-shaped recess 18 of the bearing part 12 and presses with further movement of the Wing 10 transverse to the frame level on the bearing part 12. This is due to its leadership by the collar screw 16 and through the guide bar 17 with a sliding pivoting movement acted upon it in that shown in Figure 3 or in Figure 6 Position leads. Clasped at the end of this movement the fork-like recess 19 the lifting stop 14, so that the positive engagement described occurs.

When the lifting stop 14 is fastened to the fitting part 22 the wing 10 is raised by the bearing part 12, if the fitting is attached to a vertical frame spar is and the wing is not the design predetermined Altitude. In this case, the fitting can Serve lifting the window sash and for example one otherwise replace the headstock.
