Description

The present invention relates to a closing part for a window or a door, comprising a base body and a holding part which can be coupled to the base body, wherein the holding part has at least one receiving opening for receiving a locking element of a wing of the window or the door.

Such locking members serve to selectively lock the movable wing of a window or door relative to the frame so as to prevent inadvertent opening of the window or door. For example, a closing part of the said type is fastened by means of fastening openings on the frame, while the locking element is arranged on a displaceably mounted on the wing drive rod and is linearly displaceable together with this between a release position and a blocking position. In the blocking position, the locking element of the wing - for example, a mushroom-shaped locking pin - held in the receiving opening, so that the window or door can not be opened. The boundary of the receiving opening acts as a retaining edge, which engages behind the locking element optionally. Usually, the closing parts and the associated locking element in a space between the frame and the wing, the so-called seaming air, arranged.

When mounting a closure member of the aforementioned type, problems may occur because the shape and location of the window or door components are subject to certain tolerances and the size of the folded air therefore considerably, specifically by several millimeters, can vary. A particularly pronounced enlargement of the folding air compared to a default value can occur, for example, due to a hollowing of the frame during assembly. In such cases, the function of the locking mechanism may be impaired because the holding part can no longer securely engage behind the locking element.

It is an object of the invention to allow in the assembly of closing parts of windows or doors in a simple manner, a reliable compensation of positional tolerances of the individual components and in particular of variations of the folded air.

The object is achieved by a closing part with the features of claim 1 and in particular in that on the base body at least one toothing and on the holding part at least one hereby meshing counter teeth are provided, which are arranged and aligned such that the teeth and the counter-toothing allow a fixing of the holding part to the base body optionally at different distances between the base body and the holding part. In other words, the height or thickness of the closing part can be adapted to the specific circumstances.

Due to the interaction of the teeth and the counter-toothing, the distance between the base body and the holding part in several discrete stages is adjustable. The distance can therefore be adapted to the respective installation situation, so that even with deviations in the size of the folded air of a default value, a secure operation of the locking mechanism can be ensured. Elaborate adjustment devices such as screws are not required for this purpose. Rather, the provision of gears is associated with no special manufacturing difficulties.

The toothing and the counter toothing each comprise at least one tooth and / or at least one tooth space. In particular, it may be sufficient if a single tooth optionally interacts with one of several possible tooth gaps. The different distance positions are then given by the plurality of tooth spaces.

It is preferred that the holding part is optionally fixable to the main body in at least three, preferably at least five different distances. As a result, a sufficiently accurate adjustment of the distance between the base body and the holding part is ensured in many cases to the existing seaming air.

According to one embodiment of the invention, the toothing of the main body and the counter-toothing of the holding part cooperate in such a way that optionally different toothing areas of the toothing and the counter toothing are engaged with each other.

A further embodiment of the invention provides that the toothing of the main body forms a latching toothing and the counter-toothing of the holding part forms a latching counter-toothing, so that the holding part is fixed to the main body by a latching connection, starting from a maximum distance between the main body and the holding part by exerting a force on the holding part in the direction of the base body, the holding part is temporarily displaceable in the direction of the base body with temporary overcoming of the latching in order to selectively reduce the distance between the base body and the holding part. In other words, the tooth flanks are relative to an axis Angled perpendicular to the main plane of extension of the body. A detent allows a simple change between the different distances and thus a simple adjustment of the distance between the body and the holding part to the respective installation situation.

The holding part may be formed spring-back in a direction perpendicular to a plane formed by the toothing and the counter-toothing, so as to allow a temporary overcoming of the latching.

A special embodiment of the invention provides that the latching is effective both with respect to a displacement of the holding part in the direction of the base body as well as in a direction opposite thereto. As a result, not only a reduction, but also an increase in the distance between the base body and holding part is possible, for example in the context of a subsequent correction. However, in certain applications it may be advantageous to provide unidirectional adjustability of the distance, e.g. by a corresponding shaping of the locking teeth of the toothing and the counter toothing. In particular, the ratchet teeth could be designed as undercuts.

An upper side of the holding part may have at least one bevel which is oriented obliquely such that a force acting transversely on the holding part causes a force component which presses the holding part in the direction of the main body. Under the top here is the side facing away from the body side of the holding part to understand. A force acting on the holding part in the transverse direction can force through a component of the wing, such as by a portion of the Closing member associated locking element, caused during the closing process. Thus, during the first closing of the window or the door, starting from the largest possible distance between the base body and the holding part, an automatic displacement of the holding part in the direction of the main body takes place until the correct distance is reached. That is, the closing part is self-adjusting. A fitter then has to make during installation no annoying and time-consuming manual adjustment, so that a particularly economical installation of windows and doors is possible.

Another embodiment of the invention provides that the toothing of the main body and the counter-toothing of the holding part cooperate in a form-fitting manner, wherein a desired distance between the base body and the holding part by a lateral placement of the holding member is adjustable to the body. Particularly preferred in this case is provided on the base body effective in the direction of Aufsetzbewegung guide for the holding part. In such a positive fit, the teeth of the teeth fill the tooth gaps of the counter teeth at least substantially completely and vice versa. Alternatively or additionally, the tooth flanks of the toothing and the counter toothing can extend at least substantially parallel to the main extension plane of the main body. In such a positive coupling between the base body and the holding part, a subsequent adjustment of the distance is excluded and the holding part is securely held in the once defined position.

It may further be provided that the base body and the holding part are aligned plane-parallel to each other in each of the different distances. As a result, unwanted, the closing function impairing Canting or tilting of the holding part avoided.

Furthermore, it can be provided that the toothing of the main body and the counter-toothing of the holding part parallel to a main extension plane of the base body rectilinear and / or that the teeth of the main body and the counter teeth of the holding part parallel to a longitudinal axis of the body rectilinear, wherein for mounting the closing part the holding part in a direction parallel to the said longitudinal axis can be placed on the base body. In this case, an effective guide for the holding part is preferably provided on the base body in the direction of the placement movement. The holding part can thus be placed laterally on the base body before delivery or during assembly. This is done with snap-coupled components preferably at a distance which corresponds to the largest possible distance between the body and the holding part and therefore the adaptation to a maximum folding air. A reduction of the distance as required can then take place as described above during the first closing of the wing. If the base body and the holding part are positively coupled, the lateral placement can be done from the outset in the - previously determined - correct distance, with subsequent adjustment movements are excluded.

According to a further embodiment of the invention, the toothing of the main body and the counter-toothing of the holding member parallel to a longitudinal axis of the body rectilinear, wherein the closing part has a securing device which secures the holding part against unintentional displacement relative to the base body along said longitudinal axis. As a result, an undesired displacement of the holding part in the longitudinal direction can be prevented. The safety device may be formed integrally with the holding part and / or the base body, for example as a tongue portion which engages in an associated recess. The securing device can also act snap-lock, so that the holding part snaps in a lateral placement on the body in the correct position. In principle, a separate securing element could be provided, for example a screw.

Furthermore, it can be provided that the toothing is provided on two opposite side surfaces of the main body and the counter teeth on two opposite side surfaces of the holding part is provided and / or that the counter teeth are arranged on at least one side surface of the holding part, wherein the counter teeth only in sections the said side surface is provided. That is, there is a mutual clinging between the body and the holding part. The side surfaces may in each case be directed inwards or outwards, i. they can be inside surfaces or outside surfaces. Due to the clasping, the engagement effect can be adjusted in a particularly simple and reliable manner, in particular in a configuration in which the toothing and the counter toothing interlock with one another in a snap fit manner.

Preferably, the toothing is integrally formed on the base body and the counter toothing is integrally formed on the holding part. In other words, the toothing is preferably formed directly on the base body and the counter-toothing is formed directly on the holding part. The production is simplified as a result, since no elaborately constructed toothed components have to be provided and attached.

On the base body and / or on the holding part stops can be provided which define a minimum and a maximum distance between the holding part and the base body. The margin between the minimum distance and the maximum distance can here be matched to the usually occurring fluctuations of the folded air. By such attacks in particular the pre-assembly of the holding part described above in the largest possible distance from the base body is simplified.

It is preferred that the base body is formed as, in particular plate-shaped, die-cast part and / or that the holding part is formed as a sheet metal bent part, in particular made of sheet steel. This allows a particularly simple and inexpensive production. A production of the holding part made of sheet steel allows the use of the closing part for burglar-resistant windows and doors.

As in the Fig. 1-4 a closing element 11 according to the invention for a espagnolette fitting of a window or a door is made in two parts and comprises a formed as a die-cast body 13 and a coupling with this holding part 15. The body 13 has a plurality of mounting holes 17 for attaching the body 13 to a frame, not shown Window or the door open. With the mounting holes 17 aligned through holes 19 of the holding part 15 allow access to the mounting holes 17 when coupled to the base body 13 holding part 15. As in particular in Fig. 4 is recognizable, the base body 13 is formed as an elongated plate and has both a main extension plane H 1 and a longitudinal axis L (see Fig. 1 ) on.

This in Fig. 3 individually shown holding part 15 is designed as a bent sheet metal part and preferably made of sheet steel. A main extension plane H2 of the holding part 15 extends parallel to the main extension plane H1 of the main body 13. In addition to the passage openings 19, the holding part 15 also has two receiving openings 21, which here run U-shaped and form a holding edge 25. This retaining edge 25 serves to a on a drive rod of the wing (not shown) of the Window or the door provided locking element, such as a mushroom-shaped pin, engage behind, so as to fix the wing to the frame. To release the wing, the locking element can be displaced in a generally known manner along the longitudinal axis L by displacing the drive rod until the locking element is located outside the receiving opening 21. In principle, the closing part 11 could also be displaced along the longitudinal axis L in relation to the fixed locking elements by the base body 13 being screwed by means of the fastening openings 17 to a corresponding espagnolette fitting.

The distance D between the main extension plane H 1 of the main body 13 and the main extension plane H2 of the holding part 15 can be adjusted by offsetting the holding part 15 in the direction of the main body 13 or away therefrom, as further described below with additional reference to FIG FIGS. 5 and 6 is explained in more detail.

At the two outer side surfaces 27 of the main body 13 are respective teeth in the form of a single, in the direction of the longitudinal axis L rectilinearly extending latching tooth 29 (FIG. Fig. 5 ) intended. These two locking teeth 29 are engaged with corresponding counter teeth 30 of the holding part 15 in engagement. The counter teeth 30 each have 4 teeth and 5 tooth spaces and are integrally formed on inner side surfaces 31 of the holding part 15, which are formed by bent edge strips 33 of the holding part 15. The locking teeth 29 and the counter teeth 30 allow by their interaction a determination of the holding part 15 on the base body 13 optionally at different distances D.

In the illustrated embodiment, the locking teeth 29 and the counter teeth 30 are formed such that when exercising a sufficient great force on the holding part 15 transversely to the main extension plane H 1 ( Fig. 4 ) with temporary overcoming of the latching connection an increase or decrease in the distance D can be achieved. As in particular from Fig. 3-6 shows the ratchet teeth 29 and the counter teeth 30 do not extend over the entire length of the body 13 and the holding part 15, but only within end-side edge regions 35. In the intermediate central regions 37 is by lateral projections 39 of the base body 13 and this encompassing clip portions 41st the bent edge strip 33 of the holding part 15 a formed in the direction of the longitudinal axis L effective linear guide. At the same time the clip portions 41 act in their interaction with the projections 39 as stops, which set the maximum distance D. A minimum distance D, which is zero here, is determined by the fact that the underside of the holding part 15 abuts against the upper side of the main body 13.

The closing part 11 is in the in Fig. 5 shown delivered state, wherein the holding part 15 is latched in the maximum distance D from the base body 13 with this. Should the seaming air of the associated window or the associated door be smaller than corresponds to this maximum distance D, during the first closing of the wing, a portion of its locking element presses laterally onto the holding part 15, wherein a ramp 43 of the holding part 15 causes a force component which causes the Holding part 15 transversely to its main extension plane H2 ( Fig. 3 ) presses in the direction of the main body 13. In this way, the holding member 15 is as long as in the direction of the main body 13 is offset until the locking element at the first closing of the wing starting from the maximum distance D between the base body 13 and the holding part 15 with temporary overcoming the latching connection between the locking teeth 29 and the counter teeth into the reception openings 21 can reach what the correct distance D - as exemplified in Fig. 6 shown - reached. A co-operating with the run-up slope 43 of the holding part 15 bevel of the locking element or other provided on the wing fitting part can hereby supportive act. The closing member 11 is thus self-adjusting, that is to say when mounting are no manual settings.

According to a non-illustrated embodiment of a closing member according to the invention teeth of the base body 13 and counter teeth of the holding member 15 do not act rastschlüssig, but form-fitting together, so that a subsequent adjustment of the distance D is excluded. The setting of the desired distance D between the base body 13 and the holding part 15 can be effected by a lateral placement of the holding part 15 on the base body 13 and a displacement along the longitudinal axis L.
