EP0774557A1 - Additional fitting for windows, doors or the like - Google Patents

Abstract

The accessory fitting is applied to doors or windows, and has two parts which can each be attached to a frame or casement. One part is a hook component (1) with at least one hook projection (2), and the other part is a component (3) with one or more openings (4) in which the hook projection can engage. The projection is directed away from the other component, and the position of engagement results from a relative movement of the components in a plane which is parallel to that of the window. The fitting may have a position in which the hook projection grips from above, and may also have a support (5) for the engagement opening, in both the engaged and not-engaged positions.

Description

The invention relates to an additional fitting consisting of two fitting parts for doors, windows or the like, in particular for tilt and turn windows.

Such an additional fitting is known on the market. The known fitting has a hook part, which has hook extensions and can be mounted on the window sash. The hook extensions protrude laterally beyond the wing into hook engagement openings which are assigned to a hook engagement part which can be mounted on the frame of the window. In the known fitting, the hook engagement openings are assigned to a bar which can be pivoted about an axis and which can be pivoted into the hook engagement opening.

From GB-PS 20 98 271 an additional fitting is known, in which also a hook part with hook extensions in hook engagement connection occurs to a hook engagement part.

The invention has for its object to improve a generic fitting security.

The object is achieved by the invention specified in the claims.

As a result of the development according to the invention, the hook extension is directed away from the hook engagement part. The engagement position is achieved in that the hook extension and the hook engagement opening are displaced relative to one another parallel to the window plane. There is a carrier, which the hook engagement openings are assigned, and the hook continuation preferably in an overlapping position, which overlapping position is retained both in the engaged position and in the disengaged position. When the fitting is moved from the engaged position to the disengaged position, the overlap can be increased. Either the hook extension or the hook engagement opening is preferably assigned to a slide which is displaceable in the window plane. In particular, the hook engagement opening carrier is designed as a slide. The hook engagement openings can be formed from an angled portion of this slide. The slide can be displaceable from a rotary handle, which in particular has an eccentric section. A preferred embodiment of the invention provides that the hook engagement part can be struck on the wing and the hook part on the frame. The slide can also be fixed in its locked position by means of a pressure cylinder. The pressure cylinder can either block the slide or the operability of the rotary handle. The hook part can be U-shaped, one U-leg forming a fastening section or a fastening plate and the other U-leg one or more mutually parallel hook extensions, each of which includes hook engagement openings of a cross-movable carrier. The drive gear for the slide is designed so that the slide is locked in its two end positions against pushing back. In particular, the slider should be locked against pushing back in the hook engagement position. If, for example, during a break-in attempt, a lever tool is placed between the frame and the sash in order to release the connection between the frame and the sash, then according to the design of the fitting according to the invention the hook part is removed from the Hook engagement part spaced, due to the hook projections directed away from the hook engagement part, however, the latter engage deeper into the hook engagement openings and thus increase safety, since the hook engagement runs in the opposite direction to the expected violent opening direction. The fitting is preferably attached to the hinge side of a tilt and turn window. The hook extensions engage with play in the hook engagement openings, so that a pivot opening of the window is possible in the engaged position of the fitting, the angled portion of the hook engagement carrier having the hook engagement openings swivels over the hook extensions in a position in which there is no hook engagement position when the window is opened. When the window is closed, the hook engagement openings move again on a swivel path over the hook extensions in such a way that a hook engagement position is present when the window is closed. In order to enable the window to be tilted, the slider is to be displaced such that the hook engagement openings are displaced in the direction away from the wing, so that the hook extensions protrude from the associated openings and the window can be freely tilted. Fastening screws for the hook engagement part are only accessible in the disengaged position. In the engaged position, the openings of the fastening screws are covered by sections of the slide.

The fitting shown in the drawings consists of two fitting parts, namely the hook part 1 which can be screwed onto the frame with a fastening plate 8 and which can be screwed directly adjacent to a wing that strikes the frame on the wall side of the window. Adjacent to the hook part 1, a hook engagement part 3 can be screwed onto the wing, which carries the hook engagement openings 4 which overlap the hook extensions 2.

The hook engagement openings 4 are associated with a bend 7 of a hook engagement opening carrier 5, which is designed as a slide 6 and can be brought from the hook engagement position shown in FIG. 3 into the disengaged position shown in FIG. 7 by means of a rotary handle 9.

The hook part 1 is essentially U-shaped, with a total of three U-shaped hook angles arranged one behind the other, so that one leg of this U-hook angle forms the hook extension 2 and the other leg forms the common screw-on plate 8 with which the hook part 1 is attached Frame is to be attached.

The hook engagement part has a total of three superimposed metal plates 6, 12, 13. A base plate 12 is screwed to the rear of the wing via fastening screws which can be pushed through openings 14. The base plate 12 is screwed to the cover plate 13 by means of screws 19. Between the base plate 12 and the cover plate 13, the slide plate 6 is transversely displaceable. The slide plate 6 covers the openings 14 in the engaged position, so that the fastening screws are only accessible in the disengaged position. For this purpose, the slide has a recess 18 or a passage opening 15 which, in the disengaged position, is displaced via the openings for the fastening screws.

A rotary handle 9, the diameter of which corresponds essentially to the width of the fitting, lies on the outer surface of the cover plate 13, projects through the cover plate with a cylindrical extension 10 and projects into an elongated hole opening 17 of the slide with an eccentric extension 11. The eccentric section 11 is circular in cross section. To assemble the fitting, the cover plate 13 has an opening adapted to the eccentric section 11, through which the eccentric section 11 can be inserted during assembly, so that the eccentric section 11 lies in the mounted position in the plane of the slide 6.

By turning the rotary handle 9 by 180 °, the slider, which has the hook entry openings 4 at its angled position, can be displaced transversely, so that the hook entry openings 4 can be brought to the hook extensions 2 in the disengaged position. The rotary handle rotates about a pin 16, in particular screwed into the extension 10, 11, which lies in a circular opening in the base plate 12 which is adapted to the diameter of the pin 16.

Both in the setting shown in Fig. 2, as well as in the disengaged position shown in Fig. 6, the eccentric portion 11 is in a dead center position to the longitudinal opening 17 of the slide 6, so that a backward lock is effected.

It is considered an advantage of the invention that the bend 5 extends over the hook extensions 2 and must be displaced in the direction away from the wing in order to achieve the disengaged position. The shift takes place in the plane of the wing and is a linear shift. It is also conceivable that the hook engagement openings are attached to the frame and that hooks are assigned to the slide. Even then the arrangement is such that the relative displacement from the hook entry opening to the hook extension to reach the hook engagement position is the same direction as the expected relative displacement direction from the hook part to the hook engagement part when the window is opened by force.

It is also envisaged that the fitting can be arranged on the lock side of the window. Then the disengaged position must be reached in both the rotary and the tilt opening.

The screws 19 connecting the base plate 12 to the cover plate 13 pass through elongated holes in the slide plate 6, so that the slide plate 6 is thereby guided. The slide plate 6 essentially fills the entire narrow space between the cover plate 13 and the base plate 12, which gives the entire fitting a very flat design.

All the features disclosed are essential to the invention. The disclosure content of the associated / attached priority documents (copy of the prior application) is hereby also included in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
