Abstract

The closure element (11) comprises a base body (13) and a holder portion (15) mounted on the base body in a vertically adjustable manner. The holder portion comrpises a receiving opening (21) for receiving a locking element of a leaf of the window or the door. A magnetic area (33A,33B,33C) is provided at the holder portion, which comprises a permanent magnet or is ferromagnetically designed. The holding portion is displaceably mounted on the base body, particularly between a retracted position and an extended position. An independent claim is included for a connecting rod fitting of a window or a door.

Description

The present invention relates to a closing part for a driving rod fitting of a window or a door with a base body and a height-adjustable mounted on the base body holding part, 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.

By adjusting the height of the holding part relative to the base body, an adjustment of the height or thickness of the closing part can be made to the folded air. However, such height adjustments that are to be performed individually for all to be mounted closing parts, time-consuming and annoying.

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 by the fact that at least one magnetic region is provided on the holding part, which comprises a permanent magnet and / or which is formed ferromagnetically. The permanent magnet can cause a magnetic attraction force on a ferromagnetic portion of the wing-side fitting when closing the wing and thus move the holding part for height adjustment relative to the main body. Likewise, a permanent magnet of the wing-side fitting attract a ferromagnetic magnetic region of the holding part and thereby move the holding part for height adjustment relative to the main body. By automatically moving the holding part By magnetic force, the closing part is automatically set to the maximum possible height when closing the wing. A retraction of the holding part in the sense of a reduction in height can be done if necessary by a mechanical interaction between the receiving opening and the locking element. As a result, the height or thickness of the closing part adapts automatically to the specific circumstances, that is, the closing part is self-adjusting. An installer must therefore make no annoying and time-consuming manual height adjustment during installation, so that a particularly economical installation of windows and doors is possible.

Due to the magnetic height adjustment of the closing part, a reliable function of the closing mechanism can be ensured even with deviations in the size of the folded air from a default value. Elaborate adjustment devices such as screws are not required for this purpose. Rather, the provision of a magnetically active region on the holding part of the closing part is not associated with any particular production engineering difficulties.

Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.

Preferably, the holding part on the base body, in particular between a retracted position and an extended position, slidably mounted. A sliding bearing can be accomplished by a simple sliding.

It is further preferred that a particularly exposed front surface of the at least one magnetic region is arranged facing away from the main body. In other words, the front surface of the magnetic region Preferably, in the extension direction of the holding part, ie with mounted closure member and closed wing in the direction of a faceplate or a drive rod of the wing, so that the magnetic attraction for the extension movement is particularly large.

An embodiment of the invention provides that the base body comprises a ferromagnetic portion and has a particular exposed back surface of the magnetic region designed as a permanent magnet in the direction of the ferromagnetic portion of the base body or that the base body comprises a permanent magnet and a particular exposed back surface of the ferromagnetic magnetic region in the direction the permanent magnet of the base body has, so that when the holding part is extended by interaction of the permanent magnet and the ferromagnetic portion on the holding part, a magnetic "retraction" acts. That it can be achieved analogous to an automatic extension of the holding part and an automatic retraction of the holding part, when about the wing is opened and the magnetic region of the holding part is no longer attracted to the wing-side fitting. The automatic retraction is advantageous in that at a low clearance air impairment of the locking mechanism is avoided due to a too far extended holding part. In addition, an undesirable hanging down of the holding part with the sash open and the upper frame member horizontally mounted closing part is avoided.

It should be noted that the mentioned retraction force acts even with the wing closed. However, the magnetic force ratios can easily be dimensioned such that the magnetic extension force is greater when the wing is closed than the - always the same - magnetic retraction force.

In particular, the magnetic axis of the permanent magnet can run parallel to an adjustment direction of the holding part in order to maximize the magnetic force in the extension direction. The permanent magnet can be tightened in the simplest case by a made of sheet steel and thus ferromagnetic cuff rail of the wing-side fitting. In the case of an already made of sheet steel espagnolette fitting thus no modifications to the wing-side fitting parts are required.

Furthermore, the at least one magnetic region can be formed by a permanent magnet or by a ferromagnetic component which is arranged in a recess of the holding part. This allows a particularly space-saving design. In particular, the recess may be completely filled by the permanent magnet or the ferromagnetic component.

According to a special embodiment, the permanent magnet or the ferromagnetic component is arranged in a passage of the holding part, which runs parallel to an adjustment direction of the holding part. The permanent magnet or the ferromagnetic component then has both an exposed front surface and an exposed rear surface, which can interact optimally with corresponding opposing magnetic regions of the wing-side fitting or the base body.

On the base body and / or on the holding part stops may be provided which define a minimum and / or maximum adjustment of the holding part relative to the main body. The span between the minimum adjustment and the maximum adjustment can be here be tuned to the usually occurring fluctuations of the seaming air. By such stops the Ausfahrweg as well as the Einfahrweg is limited to an appropriate level.

A further embodiment of the invention provides that the at least one magnetic region is arranged centrally relative to a longitudinal axis of the closing part. This tilting or tilting of the holding member relative to the body can be avoided due to the magnetic force.

Advantageously, a plurality of magnetic regions spaced from one another along a longitudinal axis of the closing part may be provided on the holding part. The magnetic force for height adjustment can be enhanced. In principle, certain magnetic areas can be provided exclusively for extension and the remaining magnetic areas exclusively for retraction.

The invention also relates to an espagnolette fitting for a window or door, comprising a closure member to be attached to the frame of the window or door, which is constructed as described above, and an espagnolette assembly to be attached to the sash of the window or door, which at least one in the receptacle opening comprises the retaining part of the closing part recordable locking element.

According to the invention, a counter-magnet area is provided on the drive rod arrangement in the region of the locking element. The counter-magnetic area may be a ferromagnetic section if the magnetic area of the holding part is designed as a permanent magnet. Likewise, the counter-magnetic region may be a permanent magnet if the magnetic region of the holding part is ferromagnetic. In principle, the magnet area of the holding part and the counter-magnet area of the drive rod arrangement could both also be designed as permanent magnets, which face each other with opposite poles. The fact that the counter-magnetic region is placed directly on or at least in the immediate vicinity of the locking element, a cooperation with the magnetic region of the holding part is ensured, since this must cooperate with the locking element in the assembled state of the espagnolette.

It can therefore be provided in particular that in the assembled state and with the wing closed, the at least one magnetic region and the counter-magnetic region are opposite each other and attract each other.

The invention further relates to a drive rod fitting for a window or a door, with a to be attached to the frame of the window or the door closing part, which is designed as described above, and to be attached to the wing of the window or the door drive rod, which at least one in the Receiving opening of the holding part of the closing part receivable locking element comprises.

According to the invention, the locking element can be movable transversely to the drive rod for an adjustment of the distance between the locking element and the drive rod and have an at least one magnetic region of the holding part attracting counter-magnetic region, which comprises a permanent magnet and / or at least partially formed of a ferromagnetic material. Due to the attraction between the magnetic region of the holding part and the counter-magnetic region, the locking element is - in addition to the holding part - moved to an extended position, so that even with large clearance air a reliable retraction of the locking element in the receiving opening the holding part is ensured and thus an impairment of the locking mechanism is reliably avoided.

According to one embodiment of the invention, the at least one magnetic region of the holding part is arranged so that it is opposite to the locking element when the wing is closed and the drive rod is in an open position. Thus, the locking element is set to maximum distance from the drive rod before insertion into the receiving opening of the holding part.

As in Fig. 1 and 2 shown is an inventive closing part 11 for a drive rod fitting of a window or a door made in two parts and includes a formed as a die-cast body 13 and a height adjustable on this support member 15, which is preferably made of sheet steel. The main body 13 has a plurality of fastening openings 17 for fastening the base body 13 by means of screws to a frame, not shown, of the window or the door. As shown, the closing part 11 is elongated, that is, it has a longitudinal axis L (see Fig. 2 ) on.

The holding part 15 also has two receiving openings 21, which here run U-shaped and form a holding edge 25. How out Fig. 3 it can be seen, this holding edge 25 serves to engage behind a respective of two on a drive rod 27 of the wing (not shown) of the window or the door locking elements 29, here in the form of mushroom-shaped pin, so as to define the wing on the frame. To release the wing can be moved by moving the drive rod 27, the relevant locking element 29 in a basically known manner as long along the longitudinal axis L until the locking element 29 is 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 holding member 15 is guided for height adjustment between a retracted position and an extended position in and against a transverse to the longitudinal axis L extending adjustment direction linearly displaceable on the base body 13, wherein the Fig. 1-4 show the holding part 15 in the retracted position. The retracted position and the extended position are determined by corresponding stops, not shown, of the main body 13 and the holding part 15.

In the holding part 15 three along the longitudinal axis L spaced-apart bushings 31 are provided, in which a central permanent magnet 33A and two outer permanent magnets 33B, 33C are used. The permanent magnets 33A, 33B, 33C form magnetic regions which cooperate with the drive rod 27, as will be explained in more detail below.

How out Fig. 1-4 shows, the exposed front surfaces 35 of the permanent magnets 33A, 33B, 33C are formed flush with the edges of the passages 31 and point in the adjustment direction V. Furthermore, the magnetic axes extend M ( Fig. 4 ) of the permanent magnets 33A, 33B, 33C parallel to the adjustment direction V of the holding part 15th

In a region located below the holding part 15, the main body 13 has ferromagnetic portions not shown, which are attracted by the permanent magnets 33A, 33B, 33C, so that the holding part 15 without the influence of other external forces in Fig. 1-4 shown retracted position occupies.

Now, if the wing of the window or the door is closed and the drive rod 27, optionally including the drive rod 27th leading faceplate, one of the closing part 11 laterally spaced position as in Fig. 3 represented in a position located above the closing part 11 as in FIG Fig. 5-7 is moved, the central permanent magnet 33A exerts an attractive force on a ferromagnetic portion 37 of the drive rod 27 and / or the associated faceplate, so that the holding part 15 moves in the extended position. The ferromagnetic section 37 located between the two locking elements 29 spaced apart along the longitudinal axis L thus forms a counter-magnet area for the central permanent magnet 33A which, when the wing is closed, faces the central permanent magnet 33A. It is understood that in a complete ferromagnetic embodiment of the drive rod 27 or the faceplate also such a ferromagnetic portion 37 is present.

From a comparison of Fig. 3 and 4 with the Fig. 5 and 6 shows that the locking elements 29 are movable transversely to the drive rod 27, that is adjustable in length. Moreover, being made of a ferromagnetic material, they form counter-magnetic portions attracted by the outer permanent magnets 33B, 33C of the holding member 15, so that they are stretched to a greater length by the magnetic attraction force.

Starting from the in Fig. 5-7 Finally, a position of the locking elements 29 is inserted into the corresponding receiving opening 21 of the holding part 15. The stretching of the locking elements 29 ensures this together with the extension of the holding part 15 a reliable closing function of the espagnolette fitting. Due to the magnetic self-adjustment manual height adjustment of the holding member 15 is unnecessary. Depending on the size of the folded air can the extension of the holding part 15 either by appropriate limit stops on the holding part 15 or by abutment on the wing, in particular on the drive rod 27 or on a covering this cover plate be limited.

It should be noted that as an alternative to the illustrated embodiment, it would also be possible to provide permanent magnets on the drive rod or on the faceplate, which act on ferromagnetic components in the passages 31 of the holding part 15. Likewise, the base body 13 may have corresponding permanent magnets for retracting the holding part by means of the ferromagnetic components.
