Description

The invention relates to a window / door handle, with a square pin for secure connection of the window / door handle with a locking mechanism a window or a door. The invention further relates to a square pin system for secure Connection of a window / door handle with a locking mechanism.

It is known for closing and opening actuation of Windows and doors provide rotatable handles. A rotary operation of such a window / door handle is usually by means of a square pin on the closing mechanism of the window or transferred to the door. The length the square pin is dimensioned so that a reliable transmission guaranteed the rotational movement is.

It can prove problematic if the window / door handle should be exchanged, for example to increase the Burglar resistance by an already existing handle Exchange handle with an additional one Replace locking mechanism. For the case that the previous window / door handle with the square pin is firmly connected, namely for the Exchange handle a separate square pin can be provided. Indeed is the free length, around which a square pin protrudes from a window / door handle to enter associated locking mechanism reliable not to be able to intervene set by default. So that the free length of the Square pin of the replacement handle to the installation depth of the existing one Adjusted locking mechanism should be the free length of the replacement handle can be variable.

For this purpose it is for example possible, for the free length of the square pin of the replacement handle a maximum required Length. At the installation site, this square pin is then cut to the actually required and shortened possible length. This However, the procedure requires the use of tools at the installation site.

To the need for use of tools at the installation location of the replacement handle must be avoided it also possible to deliver the replacement handle with different square pins of different lengths, so that the fitter can select the square pin the for the installation depth of the relevant locking mechanism the suitable free Has length.

Alternatively, it is also conceivable to store the square pin longitudinally within the new window / door handle, see above that the square pin can be moved along its longitudinal axis, around the free length or set the depth of penetration into the existing locking mechanism to be able to. Such displaceability, however, carries the risk that already mounted window / door handle the square pin inadvertently continues along its longitudinal axis moved and in extreme cases out of engagement with the locking mechanism the window or the door device.

A similar problem can arise for universal handles result in - for example with additional Bolt mechanisms to increase of burglary security - as Original equipment for different windows or doors should be suitable. Here, too, it should be ensured that for different installation depths the shooting mechanism the square pin is always securely connected to the locking mechanism.

An object of the invention is therefore in a window / door handle and to create a corresponding square pin system that is reliable for secure rotation Connection of the handle with a locking mechanism an adjustment allow different installation depths of the locking mechanism without that several square pins of different lengths are available have to and without the use of special tools on site is.

This task is accomplished with a window / door handle solved the features of claim 1, and in particular by that the square pin has several fastening sections, the along the longitudinal axis of the square pin are arranged distributed, and that at least a securing element is provided, which with the fastening sections of the square pin in a selectable axial position cooperates to determine the free length by which the Square pin from the window / door handle protrudes.

The square pin according to the invention is therefore with provided several fastening sections, which with respect to the longitudinal axis of the square pin are arranged spaced apart. At least one Securing element can with the fastening sections of the square pin cooperate to determine an axial position of the securing element and thereby the depth of penetration of the square pin into the window / door handle determine. The securing element blocks the square pin, for example against unintentional further penetration into the window / door handle. By this securing element optionally with one of the several fastening sections of the square pin, the user can predefine the free length, around which the square pin starts from the relevant window / door handle an assigned locking mechanism intervenes.

The square pin system made of square pin with fastening sections on the one hand and the locking element interacting with it on the other hand has the advantage that a new handle can be adapted to the installation depth of the existing locking mechanism to replace an existing window / door handle without having to choose from several square pins of different lengths have to. Instead, the securing element is attached to the square pin so that the resul The free length of the square pin ensures reliable engagement in the locking mechanism. The securing element prevents the square pin from inadvertently moving along its longitudinal axis even when the replacement handle is used. A special tool is not required.

To be a particularly reliable axial Fixing the square pin relative to the window / door handle can also bring about several securing elements can be provided with different of the several fastening sections of the square pin interact.

Also for a universal window / door handle that as initial equipment for different windows or doors with different installation depth of the locking mechanism should be suitable, the invention allows the required adaptability of the free length of the Square spindle.

Unless related to the invention a window / door handle Referenced is a window handle, a door handle or to understand a combination of window and door handle.

According to an advantageous embodiment the fastening sections of the square pin each at least a recess with which the securing element cooperate capable of the explained Fulfill the fixing function to be able to.

The securing element is preferred provided with at least one engaging portion that engages in such a recess or in another fastening section of the square pin.

In particular, each fastening section have at least one transverse groove into which the securing element can intervene. A transverse groove is to be understood as a groove that transverse, in particular perpendicular to the longitudinal axis of the square pin. Preferably are for each fastening section provided two mutually opposite transverse grooves, making it a particularly reliable fit the securing element guaranteed is. It is also possible, for each Fastening section to provide a single circumferential transverse groove, thus an annular groove of a square or round course.

Alternatively, each attachment section of the square pin a through engagement hole or Have engaging hole of limited depth that is transverse to the longitudinal axis of the square pin. In such an engagement hole, the securing element or an engaging portion of the same engage around the securing element in terms of the longitudinal axis of the square pin.

According to a preferred embodiment the securing element is placed on the square pin on the side. Therefor the securing element can be disc-shaped or cuff-like be formed, with a circumferential recess that the Square pin can grip around a fastening section. The outline of the securing element can in particular be U-shaped, the two legs of the U-shape the square pin on one Grasp the fastening section in order to block the square pin in terms of an unwanted Allow axial movement.

Alternatively, the securing element for example, also designed as a flexible disc with a central opening into which the square pin is inserted so that the washer encircles the square pin like a ring. Because of the flexible training the disc can engage with any of the several Fastening sections of the square pin are brought about, to block the square pin against unwanted axial movement.

Alternatively, the securing element have at least one engagement pin, which in a lateral Place the securing element on the square pin in an engagement hole protrudes. The securing element can also have a T- or E-shaped outline have, the central bar of the T-shape or the central leg the E shape into a selected one Can engage engagement hole of the square pin.

Another way to attach a Securing element on the square pin is that the Fastening sections on the longitudinal edges of the square pin each have a threaded section. The Thread sections together form a thread that runs along the longitudinal axis of the square pin extends. The securing element can in this Case be designed as a threaded nut on the thread in a continuously selectable axial position is screwed. In this embodiment it is advantageous if the window / door handle has a basic element a recess for positive Holds the threaded nut. For example, a hex nut be provided, the recess of the base being complementary hexagonal.

Alternatively or in addition to the illustrated embodiments the securing element can be the securing element or another Securing element permanently attached to the window / door handle be, this securing element having a holding device, on which the square pin can be releasably attached in a selectable axial position can. This holding device can handle the square pin within the final assembled handle to prevent unwanted axial wandering secure, and it secures the square pin at least during the Assembly of the handle against falling out. This makes the Holding device the assembly of the handle because after grasping the square pin through the holding device the square pin and the window / door handle one form a common unit, which is necessary during the following Handling does not unintentionally solve again.

Such a holding device can in particular be fastened within a recess which on the Window / door handle is provided for receiving the square pin. Preferably acts said holding device with at least one of the plurality Fastening sections of the square pin together. For example can the holding device with at least one fastening section to make a stop. For this purpose, the holding device have one or more spring arms, which in a respective recess engage the square pin.

The invention also extends on a square pin system with a square pin and a securing element of the explained Art. Such a square pin system allows for any combination of Window / door handles and locking mechanisms an adjustment of the required free length of the square pin and thus a permanently reliable non-rotating connection between the handle and the locking mechanism.

Further embodiments of the invention are in the subclaims called.

The invention is exemplified below Explained with reference to the drawings; in these show:

1 an exploded view of a window / door handle with a square pin system,

2 a bottom view of this window / door handle,

3 a side view of this window / door handle, and

4 a detailed view of the cross section along the plane IV-IV according to 3 ,

1 shows a square pin 11 Made of metal, the two opposite longitudinal sides almost over its entire length, each with several transverse grooves 13 is provided. The transverse grooves 13 are along the longitudinal axis of the square pin 11 spaced equidistantly from each other, so that a regular grid of transverse grooves 13 on each long side of the square pin 11 is formed.

1 also shows a lock washer 15 made of metal with a rectangular peripheral recess, so that the locking washer 15 has a substantially U-shaped outline. The mutually facing regions of the two legs of this U-shape each form an engagement section 17 , The two engagement sections 17 can each be in a pair of opposite transverse grooves 13 of the square pin 11 intervene positively, as will be explained below.

In addition, in 1 a grip element 19 with a lock recess 21 and a fixation process 23 , also a retaining clip 25 with two spring arms 27 , and a base plate 29 with a receiving opening 31 shown.

2 . 3 and 4 show the grip element 19 , the bracket 25 , the base plate 29 and the square pin 11 in assembled condition.

The window / door handle shown is used in a manner known per se for the rotary actuation of a locking mechanism of a window or a door (not shown in the figures). This is the base plate 29 firmly mounted on the window or door, for example screwed. The grip element 19 is on the base plate 29 rotatably fixed by the fixing process 23 into the receiving opening 31 intervenes. The square pin 11 partially protrudes into a recess 33 with a positive fit (cf. 3 and 4 ). One turn of the handle 19 is accordingly on the square pin 11 transmitted, which thereby rotates about its longitudinal axis. At its free length 35 the square pin protrudes 11 into an associated locking mechanism and is therefore able to transfer the rotary movement to the locking mechanism.

The window / door handle shown can be provided, for example, as an exchange handle for replacing an existing window / door handle. Such an exchange handle can serve, for example, to increase the security against burglary. For this purpose, inside the lock recess 21 a lock cylinder (not shown) accommodates the locking of the handle element by means of an additional locking mechanism 19 enabled in its closed position.

When replacing an existing handle with an exchange handle, the problem arises that a rotary actuation of the handle must still be reliably transmitted to the locking mechanism of the window or door in question. For this it is necessary that the square pin 11 of the replacement handle securely engages in the existing locking mechanism of the window or door, and that the square pin 11 does not inadvertently change its position in the axial direction after installing the replacement handle.

This task is accomplished by the square pin system shown made of square pin 11 , Lock washer 15 and retaining clip 25 Fulfills.

For this, the lock washer is first 15 so laterally on the square pin 11 put on that free length 35 of the square pin 11 the required penetration depth of the square pin 11 corresponds to the locking mechanism. The free length of the square pin of the previously available handle can serve as a simple guide. Due to the installation of the lock washer 15 on the square pin 11 embraces the locking washer 15 the square pin with the two legs of the U-shape 11 , and the two engagement sections 17 the lock washer 15 engage positively in a pair of opposite transverse grooves 13 of the square pin 11 on. The lock washer 15 is thus with respect to the longitudinal axis of the square pin 11 secured.

Then the square pin 11 with attached lock washer 15 so far into the recording well 33 of the grip element 19 introduced until the lock washer 15 on a boundary surface of a recess 37 at the bottom of the base plate 29 strikes. The lock washer 15 thus blocks the square pin 11 against further axial movement in the direction of the handle element 19 (see. 3 ).

In this position the square pin 11 from the bracket 25 in the well 33 of the grip element 19 recorded. The bracket 25 thus serves as a further security element. For this purpose the holding clip is 25 on the closed end of the recess 33 riveted, and the two spring arms 27 form with a transverse groove each 13 of the square pin 11 a rest. This is the square pin 11 during the further assembly of the handle also against unintentional axial escape from the receiving recess 33 secured.

The pre-assembled handle according to 2 . 3 and 4 is now mounted on the relevant window or door, for example by the base plate 29 is screwed to it. The square pin 11 now engages with its free end in the locking mechanism of this window or door. The lock washer 15 is now inside the recess 37 at the bottom of the base plate 29 captured. The lock washer 15 can therefore no longer escape laterally to the square pin 11 to release again in the axial direction. The lock washer also blocks 15 the square pin 11 now also against axial movement in the direction of the locking mechanism, because the locking washer 15 of the final assembled window / door handle rests on the outer surface of the window or door.

Regarding the illustrated embodiment, it should also be noted that the axial securing of the square pin 11 also only by means of the retaining clip 25 or by means of the locking washer 15 can be done. The bracket 25 has the advantage of particularly easy handling of the square pin 11 for the user. The lock washer 15 has the advantage that it additionally provides particularly effective protection against axial penetration of the square pin 11 , for example when trying to break in. In addition, the square pin system is made of square pin 11 and lock washer 15 Universally applicable, also for window / door handles without special structural adjustments. The use of both the bracket 25 as well as the lock washer 15 guaranteed using the same transverse grooves 13 a particularly comfortable and safe function of the square pin 11 ,
