Definitions

  • the invention relates to a rosette for the rotatable mounting of a handle for actuating at least one locking mechanism of a window or a door, with two fastening bores arranged on both sides of a tubular neck and a non-rotatable metal reinforcement plate, the central bore of which is penetrated by the neck of the rosette.
  • Rosettes of this type are usually made of plastic and they get their increased rigidity through the use of a reinforcement plate.
  • sheet metal is to be understood in the broadest sense here because this component does not necessarily have to be completely flat, as is the case with sheet metal.
  • it is usually made of sheet steel, which has a high level of strength from a material point of view. This can, for example, by expressions and the like. still be increased.
  • a unit is made from a rosette, reinforcement plate and at least one actuating handle for the window or door fitting, which is rotatably mounted thereon, the rosette with the reinforcement plate is first combined to form a subunit. Then the further assembly takes place. Otherwise, this rosette or the structural unit is attached to the vertical bar of the window frame or the door, usually screwed on with the help of two screws.
  • the disadvantage is a difficult mounting of the reinforcement plate on the neck of the rosette.
  • Pressing the reinforcement plate onto the thickened neck can also result in the rosette neck being somewhat resiliently narrowed in the event of an unfavorable tolerance position, and this then leads to the stiffness of the coaxially received actuating handle.
  • a particularly preferred variant results from the fact that at least one radially projecting latching element on the neck of the rosette in the latched position engages over the edge of the bore in the reinforcing plate.
  • At least one radially protruding locking element is attached to the neck of the rosette, in particular molded in one piece, which in the locked position of the Reinforcement plate whose hole edge overlaps from above.
  • the locking takes place resiliently and nevertheless a pushing back against the mounting direction cannot take place under the usual loads.
  • the most important thing is a ramp or the like. thought.
  • not only a radially protruding locking element is provided, but preferably at least two locking elements offset by 180 ° on the neck are used.
  • a kinematically reversed solution which consists in that the central bore of the reinforcing plate or the like has at least one radially inwardly projecting nose. has that slides during assembly along the resilient neck of the rosette and jumps into the latter when an undercut or circumferential groove is reached.
  • the locking element is designed as a wedge-shaped nose protruding over the outer jacket of the neck.
  • a nose automatically forms the above-mentioned bevel, over which the reinforcement plate is pushed during assembly. In the final assembly position, it engages under this nose with comparatively little axial play.
  • the dimensioning of the nose is to be chosen in relation to the bore of the reinforcement plate so that the reinforcement plate is always held securely even when the tolerance is unfavorable and when Tolerances come together unfavorably in another sense, the sheet can still be turned by the neck.
  • the wall thickness of the neck is reduced in the region of the latching element on the inside of the wall of the neck.
  • the reduction in wall thickness can be, for example, about 50% of the normal constant wall thickness of the neck. This improves the problem-free radial compression of the nose when the reinforcement plate is pushed onto the neck.
  • a particularly preferred embodiment of the invention provides that the reduction in wall thickness extends over a circumferential angle which corresponds approximately to three times the circumferential angle of the latching element. This improves the elastic behavior in this area when mounting the reinforcement plate. Seen in the longitudinal direction of the neck, the reduction in wall thickness can extend somewhat further than the nose over the area of the nose in the direction of the free edge of the neck.
  • each latching element there is a radial opening at the transition from the neck to the rosette body on the neck in the area of each latching element, which extends circumferentially over the reduction in wall thickness and in the axial direction from the latching element to the side facing away from the spar Area of the rosette body.
  • FIGS. 1 and 2 Essential elements of the handle fitting of FIGS. 1 and 2 are the handle 1 with the non-rotatably connected square mandrel 2 as well as a rosette 3 and a cover 4. It is essential that the handle 1 is rotatably mounted about the geometric axis 5 and axially immovable on the rosette 3 is.
  • a device shown in the drawing, but not explained in more detail below, can possibly have rotary locking positions define, for example, starting from the position shown in Figure 1, one or two successive further 45 ° or 90 ° rotary locking positions.
  • the square mandrel 2 acts on the window or door fitting in the sense of locking and unlocking, but possibly also for carrying out further adjustment movements of a fitting.
  • the rosette 3 has two peg-like projections 6 and 7 which engage in corresponding drill holes on the closing-side, preferably vertical, spar of a window or door leaf. This results in a good fixation and alignment of the rosette 3 and thus the entire handle fitting against the wing.
  • the pin-like lugs 6 and 7 each have a through hole 8 and 9 for a fastening screw, not shown. So that its head is not visible, the cover 4 is located above the rosette 3 as seen from the frame. Its size corresponds to that of the rosette, but it is lower. It consists of a very thin-walled material, preferably plastic. As a result, it is resiliently bendable in the direction of arrows 10 and 11.
  • the circumferential recess 18 of the rosette 3 is designed in the manner of an approximately rectangular fillet, which is dimensioned such that the circumferential edge 13 of the cover 4 is accommodated therein and the cover 4, as shown in FIG. 2, is flush with the rosette 3.
  • the rosette 3 is equipped with a tubular neck 19, which is optionally covered by the nozzle 14 of the cover 4 with little play.
  • the spigot 14 of the cover 4 then engages in the recess 20 at the front foot end of the handle 1 with sufficient play, as shown in FIG.
  • a reinforcing plate 21 is held captively on the rosette 3. Both form the subunit mentioned at the outset, on which the actuating handle 1 and possibly further fitting elements are later mounted.
  • the reinforcing plate 21 has a central bore 22 (FIG. 4), the diameter of which corresponds to the outer diameter of the neck 19 of the rosette 3, taking into account a customary sliding fit.
  • the locking of the reinforcing plate 21 on the neck 19 of the rosette 3 in the sense of the arrow 23 in FIG. 4 is achieved with the aid of two locking elements 24. They are attached to the outside of the neck 19, in particular integrally formed and lie opposite one another. They are preferably also at an acute angle to the transverse central axis 25 (FIG. 3). It can be seen from FIGS. 3 and 4 that, when the reinforcement plate 21 is fully installed, the locking elements 24 overlap the edge of the bore 22.
  • the reinforcing plate 21 in the receptacle 26 of the rosette 3 formed by the ribs 17 is secured against lifting and, due to the shape, also held against rotation, since the outer surface of the reinforcing plate 21 runs approximately flush with the free edge of the rib 17.
  • the latching elements 24 in the exemplary embodiment have the shape of a nose which protrudes radially beyond the outer surface 27 of the tubular neck 19 and is approximately triangular in shape and constant in thickness, as a result of which, in the direction of the arrow 28, that is to say the push-on direction of the reinforcing plate 21 , a run-up slope is formed.
  • the latching elements 24 spring back radially inward in the direction of the arrow 29.
  • the wall thickness of the neck 19 in the region of each latching element 24 is reduced by approximately 50% (FIG. 5).
  • This reduction in wall thickness is achieved by providing a recess 31 on the inside 30 of the tubular neck 19.
  • This recess 31 extends according to FIG. 6 over an angular range which is approximately three times as large as the angular range over which the latching element 24 extends.
  • the depression extends somewhat further upwards than the latching element 24. Furthermore, it is carried out downwards to the mouth plane 33 of the bore 32 of the neck 19.
  • each opening 35 is made on the neck 19 in the region of each latching element 24 (FIGS. 4 and 5). This further improves the elastic behavior of the latching elements 24. It extends in the circumferential direction of the reduction in wall thickness or depression 31 over an angle which corresponds to that of the depression 31. Viewed in the axial direction, each opening 35 extends approximately from the lower edge of the associated latching element 24 to the surface 36 of the rosette body 34 facing away from the spar. Furthermore, on the rosette body 34 there is a radially outward alignment with each latching element 24 and in the center to the opening 35 or the depression 31 Groove 37 available.
  • Two central hole enlargements 38 and 39 which extend in the radial direction and open in the form of open edges, open into the central bore 22 of the reinforcement plate 21.
  • the slot width corresponds approximately to the diameter of the screw passage holes 40 and 41 of the reinforcement plate 21, which are in extension.
  • Each of the two passage holes 40 and 41 is located, as shown in FIG. 2, on a funnel-shaped protuberance 42, which is shaped into a conical shape Recess 43 of the rosette body 34 engages.
  • the slot width of the central hole enlargements 38 and 39 corresponds at least to the diameter of a locking bolt 44 of a lock 45 inserted into the rotary handle 1.
