A fixing device (33) fixes the axial relative position between base and counter element. The base and counter elements can be formed as internal and external sleeves (or vice versa) to engage round the pin. The base element can be fixed indirectly on the pin.

Description

The invention relates to a holding device for fixing the axial Location of a square pin relative to a lock nut on the one hand and one Door or window handle on the other hand, according to the preamble of Claim 1.

Such a holding device is used in square pins are not permanently attached or molded on the door or window handle, but instead moved axially between the handle and the lock nut can be. This can be particularly the case with so-called half sets be the case in which the lock nut only with one, at one Side of the door or window arranged handle is connected. In in such a case, the holding device prevents the square pin inadvertently wanders along its longitudinal direction and thereby out Engage with the lock nut or with the door or window handle.

Holding devices are known which have a spiral spring, which surrounds the square pin and between the lock nut and the handle is arranged. These known holding devices can be wrong Dimensioning of the spring undesirably high permanent spring forces exercise the lock nut or the locking mechanism.

GB 194604 describes a device for adaptable fastening Knobs or the like on a square pin known. This The device has a threaded connection between a thread projection a knob on the one hand and a fastening ring that can be screwed to it on the other hand.

US-A-2,947,561 describes a door fitting in which two are also used Door handles by means of a threaded connection at a variable distance from each other can be attached to a square pin.

It is an object of the invention to provide a holding device which secures a square pin against unwanted axial movement and has a simple structure and simple is to use.

This task is performed by a holding device with the features of Claim 1 solved.

The square pin is thus secured in its axial position by the the basic pin attached to the lock nut and with the base element connected to the counter element on the door or window handle or rests on a corresponding rosette, or vice versa. Consequently is the arrangement of basic element and counter element within that Chamber trapped, which is standard for doors in the door profile, for example as a space between a mortise lock having the lock nut and the door surface is provided. The depth of this chamber is usually referred to as the x-dimension of the door profile.

The counter element is attached to the base element at the latest when mounting the square pin on the door or window in such a way that the axial length of the arrangement of the base element and counter element corresponds to the x dimension or is just below it. This one-time setting of the length of the arrangement of basic element and Counter element can take place automatically in an advantageously simple manner, for example by attaching the handle or the rosette the door or the window the counter element on or in the base element is pushed.

The one-time setting of the relative position of the base element and counter element is by the on the base element and / or the counter element provided fixing device permanently set so that a axial play of the assembled square pin is eliminated and no undesirable constant spring pressure forces act on the lock nut.

As a fixing device on the base element and the Interacting locking means provided with counter element, which is the axial length of the basic element and counter element arrangement preferably set and fix in a predetermined locking division. To one unintentional change, especially reduction in axial length to prevent the base element and the counter element locked thereon, can be used for overcoming the locking closure generated by the locking means required axial force between 0.5 kp and Amount to 2 kp.

In a particularly advantageous embodiment of the invention several basic elements and / or counter elements are provided, each can be coupled together. This allows the holding device can be easily adapted to very different x dimensions, namely by if necessary, several basic elements or counter elements coupled together become.

The invention also relates to a square pin with a holding device of the type described. Such a square pin can can be delivered in a preassembled state. In in this case the base element is already attached to the square pin, and the counter element is with the base element, for example, by two or three rest divisions connected.

Figures 1a and 1b each show a half-set in a plan view after complete assembly on a door. One is shown schematically Lock nut 11 of a mortise lock, one engaging in the lock nut 11 Square pin 13, a profile chamber 15 of the door, one attached to the door Rosette 17 and part of a rosette 17 penetrating Door handle 19. The with respect to the direction of extension of the square pin 13 axial depth of the profile chamber 15 is denoted by x. It corresponds to that x dimension already mentioned. The square pin 13 is with a spring plate 21 provided that an advantageous bracing of the square pin 13 within the lock nut 11 causes, but not the subject of the invention is.

Furthermore, in Figures 1a and 1b, in each case only in the left half, a base element 23 and a counter element 25 shown, the together form a holding device according to the invention. The basic element 23 is designed as an inner sleeve, which partially in the axial direction encompassed by the counter element 25 forming an outer sleeve becomes. Both elements 23, 25 encompass the square pin 13.

The base element 23 has a radially outwardly projecting collar 27, which bears against the lock nut 11, and a radial inwardly projecting fastening collar 29, which fits into a round Notch 31 is engaged on the square pin 13.

Figures 2a to 2c show the base element 23 in the unassembled state. It has two mutually opposite on its outer surface External locking areas 33, which are parallel to the circumference of the base element Have 23 extending locking tines. In addition, are on the outer surface of the base element 23 two opposite one another, molded in the axial direction guide webs 35.

FIGS. 3a to 3c show the counter element 25 in the unmounted state. It has two mutually opposite along its inner surface Inner locking areas 37 each with several parallel to the circumference extending locking tines. The counter element 25 also points along its inner circumferential surface two opposite each other, with respect to the Arrangement of the inner locking areas 37 guide grooves 39 offset by 90 ° on. The inner locking areas 37 and the guide grooves 39 extend each along the entire axial length of the counter element 25.

The holding device shown in Figures 1a to 3c is as follows assembled:

First, the base element 23 is placed on the square pin 13 in such a way that the fastening collar 29 engages in the notch 31. To For this purpose, the spring plate 21 at the level of the notch 31 a recess may be provided, which is not shown in FIGS. 1a and 1b is. Thus, the base member 23 is in the axial direction the square pin 13 fixed.

Thereafter, the counter element 25 on the square pin 13 and below pushed over the base element 23 such that the guide webs 35 engage in the guide grooves 39 and the outer locking areas 33 on the one hand and the inner locking areas 37 on the other hand, in the axial direction cover by a few rest divisions. These rest divisions are through the arrangement of the locking teeth of the outer locking areas 33 on the one hand and the arrangement of the locking teeth of the inner locking areas 37 on the other hand defines and can for example be between 0.5 mm and 4 mm, preferably approximately 1 mm.

In this way, the counter element 25 is connected to the base element 23 and secured to it against unintentional axial movement. The mutual interaction of the outer locking areas 33 and Internal locking areas 37 is namely dimensioned so that the relative position of Basic element 23 and counter element 25 only by a sufficiently high Axial force exerted on the counter element 25 can be changed. The thus pre-assembled arrangement of square pin 13, basic element 23 and counter element 25 can be delivered for final assembly.

For this, the square pin 13 is already inserted in the door Lock nut 11 inserted until the stop collar 27 of the basic element 23 bears against the lock nut 11. That locked on the base member 23 Counter element 25 is at this time, for example, by up to 10 mm beyond the door surface.

Then the rosette 17 and the door handle 19 on the rosette 17 is secured axially rotatably, plugged onto the square pin 13. Here, the rosette 17 lies on the facing end of the Counter element 25 and pushes the counter element 25 further over the Basic element 23. For this purpose, in order to overcome the locking closure between the outer locking areas 33 of the base element 23 and the inner locking areas 37 of the counter element 25 briefly a certain axial force be applied, which in turn is chosen to be sufficiently low so that which is ultimately transmitted to the lock nut 11 via the stop collar 27 Axial pressure does not damage the locking mechanism.

To complete the assembly, the rosette 17 is now fixed to the door, for example screwed.

The state thus achieved is shown in FIGS. 1a and 1b, and for different x dimensions of the door in question and thus for different ones axial relative positions of base element 23 and counter element 25. The square pin 13 is now secured in terms of its axial position: An unintentional movement of the square pin continues into the Lock nut 11 is in by the abutment of the stop collar 27 the lock nut 11 prevents. The concern of the counter element 25 on the Rosette 17, however, prevents the square pin 13 from unintentionally moved out of the door. With this play-free storage of the square pin 13 is the base element 23 and the counter element 25 no axial pressure is exerted on the lock nut 11 or the rosette 17.

By the respective on the base element 23 and the counter element 25 Latching prongs only along the outer latching areas 33 or the inner latching areas 37 are provided, can be used to overcome the Locking force required axial force particularly easily within the Predetermine the lower and upper limit explained above. Moreover prevents the provision of the locking tines only in certain areas a wedging of base element 23 and counter element 25 in the axial insertion movement.

The engagement of the guide webs 35 in the guide grooves 39 acts as an anti-rotation device, so that the outside latching areas 33 are not accidentally excepted Engage with the inner locking areas 37.

As an alternative to the area-wise expansion of the locking teeth shown these can also extend along the entire circumference of the basic element 23 or the counter element 25 extend, so that no anti-rotation is required.

Since the base element 23 and the counter element 25 each have a round one have free internal cross-section, these elements 23, 25 at a Rotary movement of the square pin 13 is not necessarily carried. Therefore there is also no undesired operation of the door handle 19 Friction between the base element 23 and the lock nut 11 or the counter element 25 and the rosette 17th

It is also possible, instead of the immediate attachment explained of the base element 23 on the square pin 13 over the mounting collar 29 to provide an indirect attachment. For this a additional fastener may be provided, the one with the Square pin 13 and on the other hand connected to the base element 23 is and can thus serve as an adapter for using the holding device for standard square pins without notch 31. For this purpose can for example also through the base element 23 in the square pin 13 grub screw to be driven.

As can be seen from Figures 1a and 1b, the inventive Holding device due to the axial displacement of the base element 23 and counter element 25 for doors with different x dimensions be used. For even greater differences in the possible x dimension to allow a correspondingly greater axial length of the base element 23 or the counter element 25 may be provided. In particular, can the fitter a selection of different long basic elements 23 and counter elements 25 are provided.

Figures 4a to 6e show an advantageous development of the invention, the also allows adaptation to very different x dimensions. In these figures are the same or similar parts as in Figures 1a to 3c provided with the same reference numerals.

Figures 4a and 4b show the figures corresponding to Figures 1a and 1b view a half-set with a square pin 13. On this one a holding device attached, which consists of a base element 23, a Counter element 25 and a further counter element 25 '.

The basic element 23 according to FIGS. 4a and 4b is like the basic element 23 constructed according to FIGS. 2a to 2c, but with a larger one axial length and a correspondingly larger axial extension of the Outside locking areas 33.

The construction of the counter element 25 according to FIGS. 4a and 4b is shown in FIGS Figures 5a to 5c shown and corresponds to that of the counter element 25 according to Figure 3a to 3c, but three on the front (Figure 5b) Snap wells 41 are provided, each along a Extend part of the outer circumference.

The structure of the additional counter element 25 '(FIGS. 6a to 6e) corresponds that of the counter element 25 with snap depressions 41 according to the figures 5a to 5c. However, additionally on the back (Figures 6b and 6e) three snap webs 43 formed, which are in accordance with the arrangement the snap recesses 41 on parts of the outer circumference of the counter element 25 'extend and protrude in the axial direction.

Around the square pin 13 for a door with a comparatively small x dimension To fix axially, it is sufficient to counter element 25 according to Figures 5a to 5c to lock with the base element 23.

In order to be able to use the holding device for a larger x dimension, the further counter element 25 'is coupled to the counter element 25 by the snap bars 43 engage the snap wells 41 of the Counter element 25 are brought. The areas that can be detected in this way at different x-dimensions is shown in FIGS. 4a (smallest x-dimension) and 4b (largest x dimension).

The dimensioning of the snap bars 43 and the ones interacting therewith Snap wells 41 should be chosen so that the for the loosening of the respective snap connection required force clearly is higher than the force required to overcome the locking between the outer locking areas 33 and the inner locking areas 37 are required becomes. This prevents that when pulling apart Basic element 23 on the one hand and an arrangement of counter element 25 and coupled with further counter element 25 'on the other hand Coupling is unintentionally released.

FIGS. 7a to 11b show a further holding device according to the invention, the same or similar parts as in Figures 1a to 6e the same reference numerals. The in Figures 7a to 11b Basic elements 23, 23 'and counter elements 25, 25' shown each have a corresponding to the outer cross section of a square pin, square free internal cross section.

The basic element 23 shown in FIGS. 7a to 7e each has External locking areas 33 on two opposite outer side surfaces and optional snap recesses 41. At the level of a rounded one to the outside Stop collar 27 protrude four fastening projections 29 'in the interior of the base element 23.

Figures 8a and 8b show a further base element 23 'with axially protruding Snap bars 43 and optional snap wells 41 and without a stop collar and without fastening projections or collars.

Figures 9a to 9d show the basic elements 23, 23 'according to figures 7a to 8b associated counter element 25. This has two inner locking areas 37, which are laterally delimited by two longitudinal slots 45. In addition, there are two optional ones on the outside of the counter element 25 Snap wells 41 are provided.

FIG. 10 shows a shorter version of the counter element 25 according to the figures 9a to 9d, without snap wells.

Figures 11a and 11b show a further counter element 25 ', which like that Counter element 25 according to Figures 9a to 9d is constructed and in addition on the back with the inner locking areas 37 with two Snap webs 43 is provided.

The assembly and operation of those shown in Figures 7a to 11b Basic elements 23, 23 'and counter elements 25, 25' take place as in the context described with FIGS. 1a to 6e:

The basic element 23 according to FIGS. 7a to 7e can be on a square pin are placed, an engagement of the fastening projections 29 ' ensure axial fixation in a notch in the square pin. Thereafter, the counter element 25 according to Figures 9a to 9d or that 10 pushed onto the square pin and on the base element 25 are locked. Since the counter element 25 at its inner locking areas 37 has only three locking tines, is during the deferral movement the same force is constantly required without increasing the required effort comes with increasing deferment depth. Sliding on is also facilitated by the longitudinal slots 45 which generate a spring effect.

The basic element can optionally be adapted to a specific x-dimension 23 according to FIGS. 7a to 7e by coupling the further basic element 23 'according to FIGS. 8a and 8b. Alternatively or in addition, the counter element 25 according to FIGS. 9a to 9d can be coupled of the further counter element 25 'according to FIGS. 11a and 11b be extended. Of course there is also a multiple extension possible. In addition, the further counter element 25 'according to figures 11a and 11b can also be latched directly to the base element 23.

The square counter-elements 25, 25 'can on their inner surface, at the end facing away from the inner latching areas 37, Have stabilizing projections or webs that are a play-free concern ensure the counter element 25, 25 'on the square pin.

• Die Haltevorrichtung 23, 25 liegt enger an dem Vierkantstift 13 an, so daß die in der Tür bzw. dem Fenster benötigte Aufnahmeöffnung kleiner sein kann.
• Aufgrund dieses engeren Anliegens des Gegenelements 25 an dem Vierkantstift 13 liegt das Gegenelement an der Stirnseite des Drückerhalses 19 an, also nicht mehr - wie in den Figuren 1a und 1b gezeigt - an der Rosette 17. Dadurch wird bei einer Drückerbetätigung, bei der die Haltevorrichtung mitgedreht wird, ein unerwünschtes Schleifen des Gegenelements 25 an der Rosette 17 vermieden.
• Da der Vierkantstift 13 von der Haltevorrichtung eng umschlossen wird, ist die Gesamtanordnung insgesamt stabiler.
• Die Führungsstege 35 und die Führungsnuten 39 sind nicht mehr erforderlich, da Grundelement 23, Gegenelement 25 und Vierkantstift 13 nicht gegeneinander verdrehbar sind.

Compared to a round design according to FIGS. 1a to 6e, the square holding device according to FIGS. 7a to 11b has the following additional advantages:

• The holding device 23, 25 lies closer to the square pin 13, so that the receiving opening required in the door or window can be smaller.
• Due to this closer contact of the counter element 25 on the square pin 13, the counter element bears against the end face of the pusher neck 19, and therefore no longer - as shown in FIGS. 1a and 1b - against the rosette 17 is rotated, an undesirable grinding of the counter element 25 on the rosette 17 avoided.
• Since the square pin 13 is closely enclosed by the holding device, the overall arrangement is more stable overall.
• The guide webs 35 and the guide grooves 39 are no longer necessary since the base element 23, counter element 25 and square pin 13 cannot be rotated relative to one another.

The elements 23, 23 ', 25, 25' shown in FIGS. 1a to 11b can as dimensionally stable injection molded parts made of plastic or as die cast parts be made of a zinc alloy. Formation of the basic element 23 made of an elastic plastic is preferred in order to postpone the Fastening collar 29 or the fastening projections 29 'on the To facilitate square pin up to the notch 31. Alternatively, you can the base element 23 have a continuous longitudinal slot in order to allow temporary spreading.
