Description

The invention relates to a mounting plate in particular for fixing handles on doors, windows and the like according to the preamble of claim 1.

Mounting handles on doors or windows is often problematic because of the handle is already axially fixed rotatably connected to a mounting plate at the factory; for example by means of crimping, riveting or with a locking ring. Especially with rosette trimmings, however, is the handle when determining the Fastening plate on the door or window sash mostly in front of those to be fixed Screws that can only be reached if you pull the handle during the Screwing down holds or if the corresponding tool is placed at an angle becomes. The attachment is therefore cumbersome and cumbersome. Another Difficulty arises if the mounting plate of the rosette with a cover cap is provided, so that this in addition to the handle in front of the to be fixed Screws.

Another disadvantage is that the pre-assembled handles take up a lot of space during packaging, which also has an adverse effect on shipping and warehousing. The latter is especially if the door or door is different for different rosettes Window handles are provided. Since a handle is not retrospectively with any Rosettes or door signs can be provided, the desired combinations be stocked accordingly.

In order to avoid the disadvantages described, it is known to handle and Mounting plate (if necessary with a separate rosette or Shield cover) separately and one between the components mentioned To provide latching device, the on-site assembly of the handle with the mounting plate allows. This is first fixed to the door or without the handle screwed to the window. Then you insert the end with a circumferential Grip groove of the handle into the mounting plate, so that an axially fixed-rotatable connection is created.

DE-U1-298 01 858 uses radially elastically extendable support flange sections as a latching device, which are spaced around the circumference of a passage opening in the Fastening plate are distributed. The individual locking sections are when inserting of the handle neck radially spread and then snap due to their inherent elasticity into the circumferential locking groove of the handle neck. Due to the distances between the locking sections however, there is only a partial locking, so that the handle only withstands low tensile forces. The permanent resilience that is important for many areas of application is accordingly low.

The same applies to a locking device known from EP-B1-0 628 680. This consists in essentially from a guide bush, which is non-positively and positively in a through hole a mounting plate is inserted and in one of the mounting plate protruding part carries a leg spring. The latter uses the invisible Attach the handle to the mounting plate after inserting two parallel spring legs tangentially into the circumferential locking groove of the Handle neck, which can hardly offer sufficient security.

With a fitting according to FR-A1-2 650 321, a bearing body is attached to a support plate axially fixed by a clamping ring. The handle neck is in the bearing body of an open bow spring held in an inner ring groove and through Inserting the neck into a bore of a bearing body to the bottom of an outer, corresponding annular groove is pressed down. In one design, the groove contains even before assembly a spring, the average diameter of which is relaxed is about the size of the hole diameter so that it is chamfered from the Front edge of the inserted neck is spread towards the bottom of the groove. The fitting can only be disassembled from the door as a whole by using the Clamping ring is released. In any case, the latched handle can be removed from the assembled Do not pull out the bearing body without great risk of damage.

In EP-A1-0 408 785 a window or door fitting is described, the handle with a neck part rotatably sits in a bearing sleeve as soon as a grooved shaft part axially is fixed by a retaining collar, especially by a spring-loaded retaining slide, the one with an auxiliary tool, a wire bracket, applied transversely to the axis of rotation the locking position can be pushed out by a linear movement. The detent sets an open form of the collar ahead, at most a semicircle boundary, so that the shaft part can only be locked in half in the groove.

From GB-A-329 937 a button fitting emerges that conically from one shoulder has a tapered handle neck with an annular groove. A pre-assembled unit is achieved by brought a stop plate on the handle neck up to the shoulder and on it is fixed by means of a snap ring, after which the whole thing can be screwed onto a door surface is. A toric ring groove is provided for the latching, into which during assembly Although a snap ring partially engages, the axial locking is limited in the essentially on a one-sided linear contact on a groove edge, so that in use sooner or later loosening or loosening of the handle will occur. A The handle can only be removed by removing the unit from the door surface and placed in a holder that allows the snap ring to be opened.

The object of the invention is to overcome the disadvantages of the prior art Technology to create a mounting plate for storing a handle that with simple components can be prefabricated inexpensively, which can be attached to a door leaf is and the locking means for the axially fixed-rotatable mounting of the insertable handle has, the locking means to withstand high tensile and shear forces. The aim fast assembly on site and great durability of the on-site handle, which should be easy to remove if necessary.

The mounting plate generally designated 10 in Fig. 1 serves the axially fixed-rotatable Fixing a door handle 40 on a door leaf (not shown). The door handle 40 consists essentially of a handle main part 41 and one of these over a shoulder 42 of a recessed handle neck 44, above a slightly conical one Handle end 45 provided with an outwardly open, circumferential locking groove 46 is. On the face side, a square bore 48 is made in the handle neck 44, in which a (not shown) square pin can be used.

The mounting plate 10 has a flat, preferably made of steel base plate 12, by means of screws (also not shown) guided in stop cams 14 is fixed to the door and with a rear stop level 16 flat on the Door leaf rests. The disk 12 carries a polygon-like shape over its outer circumference curved spring wire 20, for releasably attaching a cover cap 30, for example a round escutcheon, is designed as a locking device and on protrudes at least two opposite points over the edge 22 of the disc 12. The spring wire 20 is clamped or supported behind holding tongues 24. These are made at regular intervals within circumferential recesses 25 the steel disc 12 bent out. The rosette plate 30 is in its side Provide edge 32 with corresponding locking recesses 34 (see FIG. 2).

The steel disc 12 with a through hole is perpendicular to the stop plane 16 18 provided, in which a bushing 60 is inserted centrally. The latter supports itself a collar 61 on the back of the disc 12 and is in a corresponding (Not shown) bored hole in the door leaf to which the stop cam 14 is screwed become.

As shown in FIG. 2, the bush 60 extends through the base plate 12 of the fastening plate 10 and is on the opposite side with a predetermined axial dimension having spacer ring 70 pressed non-positively and positively. One on the outside The circumferential edge of the bushing 60 is formed with an insertion bevel 62 which facilitates the joining process, while a circumferential corrugation 63 on the outside of the bush 60 ensures a good press fit. Spacer ring 70 and socket 60 close flush from each other and form a flat bearing surface 72 for a sliding sleeve 74, the is inserted precisely into the socket 60 at the top and has a peripheral edge 76 supported flat on the bushing 60 or the spacer ring 70. To accommodate the sliding sleeve 74, the inner wall of the socket 60 is stepped.

At the level of the stop plane 16 of the steel disk 12, the bush 60 is on its inner circumference 64 with an inwardly open, circumferential guide groove 66 into which a snap ring 50 is rotatably inserted with minimal axial play. For this purpose, the latter has an angular cross section and a narrow expansion opening 51 with obliquely inwardly extending end edges 52. It can be seen in Fig. 2 that the Snap ring 50 acts as a locking element, which when the handle 40 is inserted the lined with the sliding sleeve 74 socket 60 with the circumferential locking groove 46 in Handle neck 44 engages and the handle 40 axially fixed-rotatable in the mounting plate 10 and thus at the door.

The dimensions of the snap ring 50, in particular its inner diameter, and the extent and depth of the cylindrical contact surface 47 in the locking groove 46 of the handle neck 44, are matched to one another in such a way that the snap ring 50 has the handle neck 44 in the locking groove 46 non-positively and - except for the expansion opening 51 - encloses without gaps. Furthermore, the axial distance between the locking groove 46 and the shoulder 42 of the handle 40 to the axial height of the spacer ring 70 and the sliding sleeve 74 adjusted so that the handle 40 overall with minimal radial and axial Movement play in the mounting plate 10 is rotatably mounted. Because the in the guide groove 66 pre-assembled snap ring 50 the handle neck 44 of the handle 40 always firmly encloses, it withstands even extreme shear and tensile forces.

When assembling a handle set, those without handles 40 are first separated available mounting plates 10 on both sides with the required holes provided door leaf firmly screwed and provided with a desired cover cap 30. This is simply clipped onto the steel plate 12 with its peripheral edge 32, a circumferential nose 26 serves as an alignment aid for the cap 30, the is provided with a corresponding (not visible) recess, in which at a removal tool can be inserted if necessary disassembly.

Then you simply put the handle 40 with its handle neck 44 through the in the cap 30 provided (not specified) opening into the Slide sleeve 74 and thus into the socket 60 of the mounting plate 10 until the in Guide groove 66 mounted snap ring 50 with the locking groove 46 of the handle 40 in engagement arrives and sets this axially fixed-rotatable in the mounting plate 10. Since that Handle end 45 is slightly conical, the snap ring 50 when inserting the Handle 40 automatically expanded, which makes assembly easier and accelerated. The square previously inserted between the handles 40 couples the Handles with the door locking mechanism.

In order to be able to detach the handle 40 from the mounting plate 10 again, the Provide bushing 60 with an engagement opening 68 above guide groove 66. This is used to hold a tool (not shown), e.g. a pair of spreading pliers attack the obliquely inward end edges 52 of the expansion opening 51 can.

The invention is not restricted to one of the above-described embodiments, but can be modified in many ways. So instead of a snap ring 50 use a closed rubber or plastic ring that is elastic in the Locking groove 46 of the handle 40 engages. There is also the possibility of the socket 60 and form the steel disc 12 in one piece.

It can be seen that a mounting plate 10 in particular for axially fixed-rotatable Inclusion of handles a stop level 16 for fixing the mounting plate 10 on doors, windows and the like, one in a pane 12, strip or the like. provided

Through hole 18 or bushing for the rotatable mounting of one end circumferential locking groove 46 provided neck portion 44 of a handle 40 and at least one locking element 50, which when inserting the neck portion 44 of the Handle 40 in the through hole 18 or bushing with the circumferential locking groove 46 engages and the handle 40 axially in the through hole 18 or socket defines. To the resilience of the handle 40 in the mounting plate 10 and improve their manageability, a snap ring 50 is captive in the through hole 18 or a bushing 60 inserted therein with minimal Axial play rotatably supported, after inserting the handle 40 into the mounting plate 10 a cylindrical contact surface 47 within the locking groove 46 of the handle 40 is spanned by the snap ring 50 in a substantially non-rotatable manner.
