Definitions

  • the invention relates to a device for fastening a door handle unit with two door handles in a door lock, with a mandrel provided for connecting the two door handles, which has a corresponding non-circular cross-section for non-rotatable mounting in a non-circular opening of the door lock nut, and which is in the normal operating position is cross-divided within the nut section, the two mandrel parts being releasably connected to one another.
  • the invention is an object of the invention to provide a device of the type mentioned, with which the installation or removal of the door handle unit is made possible in the simplest way, and which is nevertheless effectively secured in the attached state against loosening of the door handle, furthermore a simple one , inexpensive production should be possible.
  • the inventive device of the type mentioned is characterized in that a spring means is assigned to the mandrel and the mandrel is longitudinally displaceable relative to the nut against the force of this spring means, the length of the displacement path being at least equal to the distance of the mandrel division plane from the nut outside, and so on to be able to connect or detach the two mandrel parts when the mandrel is displaced by mutual rotation.
  • the two mandrel parts can thus only be rotated relative to one another, and in particular in the process screwed or unscrewed from each other when they have been displaced in their longitudinal direction relative to the nut, against the force of a correspondingly dimensioned spring.
  • This spring force should be such that, when the door handle unit is installed, sufficient resistance to displacement of the mandrel with the door handles is opposed when one of the door handles is actuated to open or close the door.
  • the spring must of course allow for a deliberate displacement of the mandrel so that the two mandrel parts can be connected or detached from one another. In tests, it has proven to be particularly advantageous if the spring device has a spring force of approximately 20 to 50 N, possibly up to 70 N or even 100 N.
  • the procedure is accordingly such that one lever handle with the associated mandrel part is pushed into the nut opening and then pressed against the force of the spring with the mandrel part to the opposite side of the door lock, after which the other lever handle is pressed from the other side the other mandrel part is connected to it by twisting, in particular screwed.
  • the door handle unit is then snapped back, so that both mandrel parts are then locked in the opening in the nut of the door lock and are thus secured against rotation.
  • both mandrel parts within the nut are rotatably connected to it, so that in this position twisting and thus loosening of one or the other lever handle is prevented in a simple and effective manner is.
  • the main advantages of the device according to the invention are therefore simple assembly, likewise simple generation and furthermore secure attachment of the handle unit without the possibility of loosening or pulling out of a handle, and it is also favorable that there is no visible lever handle on the door handle or the above fastening or securing device. Furthermore, it is also favorable that retrofitting existing door locks with devices or door handle units designed according to the invention is possible without problems, without changes to the door lock itself.
  • the door leaf in which the door lock is attached, to which the lever handle unit to be attached belongs is provided with rather small recesses or holes for the lever handles.
  • Low-cost for simple assembly if a coil spring is provided as the spring means, which surrounds the one mandrel part and is supported on the one hand on the door handle connected to this mandrel part or on a flange part connected to it and on the other hand on the door lock.
  • one of the door handles with the helical spring pushed onto the associated mandrel part is advantageously inserted into the nut from one side, the diameter of the helical spring being, for example, approximately the same as the diameter of the extension or shaft of the door handle.
  • a sectional or side view of a substantially C-shaped leaf spring or plate spring can advantageously be provided as a spring means for manufacturing reasons, which is supported at the end on the door lock and in The middle section, which is at a distance from the door lock, has an opening through which the one mandrel part extends, the edge surrounding the opening abutting the associated door handle or a flange part connected to it.
  • a strip-shaped leaf spring or a round disc spring can be used.
  • a leaf spring could also be provided in the case of a round recess in the door leaf.
  • the leaf or plate spring with its flange-like outwardly bent edge or edges is firmly attached to the door lock, e.g. B. screwed or soldered.
  • a quick connection in the form of a bayonet lock can be provided to connect the two mandrel parts.
  • it is advantageous to provide a screw connection and if the one of the two mandrel parts has an axial threaded bore opening on the end, the other of the two mandrel parts is simply designed with an end threaded pin that fits into the threaded bore.
  • an inner door handle 1 and an outer door handle 2 are provided.
  • “Inner” means the side with respect to the door that is opposite to the opening direction of the door.
  • the door leaf of a door is schematically illustrated at 3, the inside with I and the outside with A and furthermore the opening direction is indicated by an arrow 4.
  • the door frame is to the left of the door leaf 3.
  • the inner lever handle 1 has a mandrel part 5, which is formed in a conventional manner by a square cross section, and the longer than another mandrel part 6, which belongs to the outer door handle 2, and also by a square, square cross section , is formed.
  • the two mandrel parts 5, 6 each protrude from the respective door handle 1 or 2, forming a shoulder 7 or 8.
  • the mandrel part 5 of the inner door handle 1 carries at the end an axial threaded pin 9 which can be screwed into a threaded bore 10 of the other, outer door handle 2 so that the two door handles can be connected to one another.
  • a coil spring 11 is also arranged, which has approximately the same diameter as the door handle 1 and is supported on the shoulder 7.
  • the helical spring 11 can have a narrowed end turn in the region of the shoulder 7, so that it sits in a kind of clamp fit on the square mandrel part 5.
  • FIG. 2 shows this lever handle unit in the state in which it is fastened in a door or in a door lock 12. It can be seen that the two mandrel parts 5, 6 abut one another with their end faces and thus together form a mandrel divided in the plane of their end faces. The division plane runs approximately in the middle of the door lock 12 or of its nut 12a.
  • the door lock 12 or its nut 12a has an opening corresponding in cross section to the cross section of the mandrel parts 5, 6, as is conventional per se, and in this opening 13 the two mandrel parts 5, 6 are rotatably but axially displaceably mounted.
  • the outer door handle 2 rests with its shoulder (8 in FIG.
  • the door handle unit can be seen relative to the door lock 12 by a certain distance which is greater than the distance of the parting plane of the two mandrel parts 5, 6 from the right side of the door lock 12 in Fig. 2, to the right, as with an arrow 14 is illustrated, namely against the force of the screw spring 11.
  • the shoulder 7 of the inner door handle 1 is at a greater distance from the side of the door lock 12 facing it than the parting plane of the two mandrel parts 5, 6 from the opposite one Side of the door lock 12, and it can therefore, if the door handle unit is to be removed, this door handle unit as a whole be moved to the right until the parting plane between the two mandrel parts 5, 6 lies outside the opening in the nut 12a of the door lock 12, after which the outer door handle 2 can be rotated to unscrew it from the threaded pin 9 of the inner door handle 1.
  • the inner door handle 1 with its mandrel part 5 is first inserted into the opening 1 in the nut of the door lock 12 and pushed so far against the force of the coil spring 11 that the end face of the mandrel part 5 is on the opposite side of the Door lock 12 appears. Then the outer door handle 2 is screwed onto the threaded pin 9 of the inner door handle 1 until the two end faces of the mandrel parts 5, 6 abut at least substantially against one another, and until the two door handles 1, 2 and their mandrel parts 5, 6 are aligned with one another.
  • FIG. 2 conventional key plates 15, 16 are also shown, which are used to mount the door handles 1, 2, as is known per se. Furthermore, a conventional recess 17 in the door leaf 3 is illustrated in FIG. 2, through which the lever handles 1, 2 are turned on can be added, and which is covered by the key plates 15, 16.
  • the thickness of the square mandrel parts was 8.5 mm, and the threaded pin 9 had an M6 thread.
  • the diameter of the door handles 1, 2 at least in the shaft sections adjacent to the mandrel parts was approximately 16 mm, and a coil spring with a spring force of approximately 50 N was provided as the spring.
  • the material thickness of the coil spring made of steel was approximately 1.5 mm.
  • a plate spring 18 ' is provided which, as shown in the side view, is essentially C-shaped and has a flange 19 which is bent outward in the manner of a flange bears laterally on the door lock 12.
  • this plate spring 18 ' In its central section, which is at a distance from the door lock 12, this plate spring 18 'has an opening 20 through which the inner lever handle 1 with its mandrel part 5 is inserted. The edge of this opening 20 is supported on the shoulder 7 of the lever handle 1.
  • the operation of this arrangement according to FIG. 3 is completely identical to that according to FIG. 2, so that it does not need to be repeated.
  • the recess 17 in the door leaf 3 in the case of FIG. 3 is larger in cross section than that according to FIG. 2.
  • FIGS. 4 and 5 Such a configuration is shown in FIGS. 4 and 5, the plane of the drawing in these FIGS. 4 and 5 being rotated by 90 ° in comparison to FIG. 2 or 3, i.e. instead of a horizontal cut, a vertical cut through the door leaf with the handle unit is illustrated.
  • the outer lever handle 2 carries a mandrel part 6 provided with a threaded pin 9, whereas the mandrel part 5 provided on the inner door lever 1 has an associated threaded bore 10. Furthermore, this arrangement differs from the previous one in that an elongated, strip-shaped leaf spring 18 is provided, which rests with its upper end and lower end on the door lock 12 and there, for example by screwing, soldering, gluing or the like the door handle 1, 2 is attached, as schematically illustrated at 21 in FIG.
  • the inner handle 1 with its mandrel part 5 is again through an opening 20 in the central web part of the leaf spring 18 (which can be, for example, 1/2 cm-1 cm wide and made of spring steel) and through a square opening 13 in the nut 12a of the door lock 12 is pushed in and pushed through until the square 5 appears on the opposite, outer side and the outer handle 2 with its mandrel part 5 or its threaded pin 9 can be screwed in.
  • the unit then snaps back according to the force of the leaf spring 18 into the normal operating position shown in FIG. 5, in which the two mandrel parts 5, 6 are secured against mutual expansion by the nut 12a, as has already been explained in detail above.
