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 in the normal operating position is cross-divided within the nut section, the two mandrel parts being releasably connected to one another.
  • US Pat. Nos. 503 203 and 565 108 finally describe generic devices in which a cross-split mandrel is provided, the two mandrel parts being screwed together.
  • a screw is provided which extends as a separate component through the one half of the mandrel, and must be screwed into the other half of the mandrel when the button or pusher is removed.
  • additional, relatively complex measures are also required here in order to attach or detach the respective button or pusher or to allow access to the screw head.
  • 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 the mandrel Spring means are assigned and the mandrel is longitudinally displaceable relative to the nut against the force of these spring means, the length of the displacement path being at least equal to the distance of the mandrel division plane from the nut outside, so as to connect or detach the two mandrel parts when the mandrel is displaced by mutual rotation to be able to.
  • the two mandrel parts can thus only be rotated relative to one another and in particular screwed or unscrewed from one another if 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 used 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 then Both mandrel parts are engaged in the opening in the nut of the door lock and are thus secured against twisting.
  • 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 door handle unit to be attached belongs is provided with rather small recesses or holes for the door handles, it is favorable for simple installation if a coil spring is provided as the spring means which surrounds a 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.
  • the one lever handle with the helical spring pushed onto the associated mandrel part is advantageously inserted into the nut from one side, the helical spring having a diameter for example, can be approximately equal to 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 being in contact with the associated door handle or with a flange part connected to it.
  • a strip-shaped leaf spring or a round plate 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 is firmly attached to the door lock with its flange-like bent edge or edges, e.g. screwed or soldered on.
  • 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 face, the other of the two mandrel parts is simply designed with an end threaded stud fitting into the threaded bore hole.
  • FIGS. 1 and 2 an inner door handle 1 and an outer door handle 2 are provided. Below is 'inside' to understand that side, related to the door, that is opposite to the opening direction of the door.
  • Fig. 2 the door leaf of a door is schematically illustrated at 3, the inside with I and the outside with A and also the opening direction with an arrow 4 are indicated. According to the illustration in FIG. 2, the door frame not illustrated in the drawing is to be thought of to the left of the door leaf 3.
  • the inner door handle 1 has a mandrel part 5, which is formed in a conventional manner by a square cross-section, and which is longer than another mandrel part 6, which belongs to the outer door handle 2, and which also has a 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 has an axial threaded pin 9 on the end face, 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 coil spring 11 can be in the region of the shoulder. have a narrowed end turn, so that it sits in a kind of clamp on the square mandrel part 5.
  • FIG. 2 shows this lever handle unit in the state 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 level runs approximately in the middle of the Door lock 12 or 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. 1) on the right side of the door lock 12 in FIG. 2.
  • the shoulder (7 in FIG. 1) of the inner door handle is at a distance from the left side of the door lock 3 in FIG. 2, and the coil spring 11 (FIG. 1) is supported on the side of the door lock 12, whereby it is in the 1 is compressed and thus exerts a force on the inner door handle 1 in the direction away from the door leaf 3.
  • 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, specifically 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 therefore, if the door handle unit is to be removed, this door handle unit can 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 lever handle 2 can be rotated to unscrew it from the 6 thread pin 9 of the inner lever handle 1.
  • the inner door handle 1 with its mandrel part 5 is first inserted into the opening 13 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 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 at least substantially abut one another, and until the two door handles 1, 2 and their mandrel parts S, 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 door handles 1, 2 can be inserted, and which is hidden 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.
  • the door handle unit according to FIG. 3 largely corresponds to that according to FIG. 2, so that a new detailed explanation of this door handle unit may be unnecessary.
  • a plate spring 18 is provided, which, as shown in the side view, is essentially C-shaped and with its flange 19 bent outwards on the flange Door lock 12 bears laterally.
  • 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.
  • the outer door handle 2 carries a mandrel part 6 provided with a threaded pin 9, whereas the mandrel part 5 provided on the inner door handle 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. Type of fastening is attached before the lever handles 1, 2 are inserted, as is schematically illustrated at 21 in FIG. 4.
  • 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 inserted and pushed through in the nut 12a of the door lock 12 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.
  • the plate spring 18 (or also a corresponding leaf spring) can sit on the mandrel part 5 in a clamped fit.
  • the mandrel parts 5, 6 can, as is known per se, be made both in one piece with the pushers 1, 2 and as separate parts which are subsequently connected to the pushers, e.g. poured into them.
