Definitions

  • the cylinder housing has a first bore portion extending from its first axial end and terminating in a second, second bore portion, reduced in cross-section with the first bore portion, which is guided to the second axial end of the cylinder housing.
  • the cylinder core has a portion received in the first bore portion and carrying a coupling lug extending through the second bore portion and axially projecting beyond the second axial end of the cylinder housing.
  • a solid guide member is attached, in which an adapter is mounted, which is rotatably connected to the coupling approach.
  • the adapter may carry, for example, a locking bolt, closing lever, locking hook or the like.
  • a spring rod in the form of a round wire, which is repeatedly bent to form a clamping end, a starting end and an intermediate region. With the clamping end it is fixed to the cylinder housing. Its starting end can be acted upon by a tool, so that the intermediate region of the spring rod is movable out of engagement with an annular groove in the coupling approach. The cylinder core can then be pulled out and replaced by another one.
  • the spring bar is between held the guide member and the cylinder housing in a recess.
  • the disadvantage is that due to the guide member that completely absorbs the adapter, the lock cylinder builds a long total.
  • the starting end of the spring bar is located in a recess of the cylinder housing, which is accessible from the Zuhaltekanal via an insertion and a center hole through a wire-shaped tool.
  • the wire-shaped tool is inserted axially therein, and by exerting an axial force on it, the end of the thin wire-shaped tool acts on and deflects the inclined starting end of the spring rod laterally to move the intermediate portion out of the annular groove in the coupling projection.
  • Unfavorable is the applied high axial force. Furthermore, even smaller tolerance deviations have a negative effect on the effect of the tool.
  • the invention has for its object to provide a lock cylinder, which builds short, which nevertheless provides a secure guidance of the adapter and in which the operation for the release of the cylinder core is made easier and safer.
  • the special storage of the adapter leads to a short-lasting lock cylinder and a particularly favorable operation for the change process.
  • the adapter is rotatably fixed in the third bore stage by a retaining element which is fastened to the cylinder housing.
  • this may have a resilient approach, which is intended to engage with a recess in the adapter to set the cylinder core in a unique position.
  • the holding element is represented by a sheet metal part.
  • this can additionally have holding leg, which can be used to the cylinder housing on a thin-walled component, for example, on the front panel of a drawer or on a door, which are made of sheet metal set.
  • the holding element is provided with stops that work together with stops on the adapter. It is additionally possible to make the retaining element so that it can be fixed in different rotational positions to the cylinder housing about the longitudinal axis. This makes it possible to make a simple adaptation to different applications of the lock cylinder.
  • the spring bar is preferably made of a round wire.
  • the guide channel extends in a plane which contains the longitudinal axis.
  • the closer design of the cylinder housing 1 can be seen, which has the longitudinal axis 2.
  • the cylinder housing 1 has a first axial end 3 and a second axial end 4.
  • a flange plate 5 for fastening the cylinder housing 1 to a piece of furniture is shown on the cylinder housing 1.
  • the cylinder housing 1 has a first bore section 6, which starts from the first axial end 3. This ends in a first step surface 7. From this first step surface 7 is a reduced in cross section to the first bore portion 6 second bore portion 8 from. This ends in a second step surface 10, which is formed by a third bore portion 9, which extends from the second axial end 4 of the cylinder housing 1 and has a cross section which is enlarged in relation to that of the second bore portion 8.
  • the step surface between the third bore portion 9 and the second bore portion 8 carries the position mark 10.
  • In the first bore portion 6 extend a plurality of circumferentially distributed, but at least two Zuhaltekanäle, one of which is denoted by 11 and extending parallel to the longitudinal axis 2.
  • first step surface 7 and the second step surface 10 extends in the circumferential direction about the longitudinal axis 2 to the retaining channel 11 aligned a curved opening 12.
  • This has the shape of a curved slot whose walls or boundary surfaces are arranged concentrically to the longitudinal axis 2.
  • a recess 13 is incorporated, which is bounded by two standing at an angle boundary surface 14 and communicates with the opening 12.
  • the opening 12 approximately diametrically opposite to the recess 13 is followed by a recess 16.
  • a marking 17 is attached to the cylinder housing 1, which will be explained later and which can be seen from FIG.
  • a bent spring bar 18 made of a round wire is fixed with its one end 19 in the recess 16.
  • the other end 20 projects into the region of the opening 12, wherein this end can be bent and extends into the aperture 12.
  • the spring bar 18 may be arranged crossing the opening. In the intermediate region between the two ends 19, 20 of the spring bar 18 is angled. In the locking position according to Figure 2 are thereby the angled portions at a distance from the boundary surfaces 14, 15 of the recess 13. From the second axial end 4 of the cylinder housing 1 are axially four pins 21 before.
  • the cylinder core 22 accommodated in the cylinder housing 1 will be described in more detail below, the design of which can be seen in particular from FIGS. 1 to 3, 5 and 7 and 8.
  • the cylinder core 22 includes a core portion 23 and a coupling lug 26 and a collar 24 at the end remote from the coupling lug 26.
  • In the direction of the coupling projection 26 of the cylinder core 22 has a circumferential about the longitudinal axis 2 annular groove 27 for engagement of the spring rod 18.
  • a keyway 25 for insertion of a key is present. This communicates with apertures which are open to the outer surface of the core portion 23.
  • a guide channel 28 is arranged in the outer contour of the core portion 23 and through the collar 24, which has a first channel portion 28a in the region of the collar 24 and a channel portion 28b at the end remote therefrom.
  • the channel portion 28a is used for insertion of the wire-shaped tool 29.
  • the cylinder core 22 can, as shown in Figure 7, are pulled out of the cylinder housing 1.
  • the spring bar 18 is held by a, in particular from Figures 1 and 5 and 6 apparent adapter 30 which has a recess 31 in its periphery.
  • the adapter 30 is mounted with its guide portion 32 in the third bore portion 9 and receives through this due to a relatively large diameter, a stable leadership.
  • the adapter 30 has a bore 37 which is adapted to the shape of the coupling projection 26, so that it is non-rotatably connected to the coupling projection 26 and is likewise swiveled by a key when the cylinder core 22 is pivoted accordingly.
  • the adapter 30 further has a connecting portion 33 to which, for example, a closing lever, locking hook or the like locking element can be connected.
  • the adapter 30 is held securely in its seat in the third hole stage 9 by a relatively thin and thus short-lasting holding element 34, which is a sheet-metal shaped part.
  • the holding member 34 has bores which are formed corresponding to the pin 21 at the second axial end 4 of the cylinder housing 1 and is defined by the pin 21 after deformation.
  • the holding element 34 has a resilient projection 35, which cooperates with the recess 31 in the adapter 30 and serves to fix the rotational position of the cylinder core 22.
  • this and the holding element 34 are provided with stops 38, 39.
  • the rotational position of the cylinder core 22 can be adapted to different arrangement positions of the lock cylinder.
  • the force required for the actuation of the spring bar 18 to bring it into the unlocked position substantially reduced, whereby the handling is improved.
  • the selected arrangement is less sensitive to manufacturing tolerances, as in the direction of rotation a sufficiently large way can be made available to achieve a safe disengagement of the spring rod 18.
  • FIG. 9 shows a further possible embodiment for a lock cylinder, which is particularly suitable for use with furniture made of sheet metal, the difference to the embodiment according to FIGS. 1 to 8 being merely that the flange plate is omitted and the cylinder housing 101 is omitted a corresponding collar is provided, which rests against the front surface of the furniture.
  • the axial securing is taken over by the retaining element 134 which is provided with retaining legs 36 which extend in the direction of the first axial end and which are resilient and bear against the rear surface of the furniture part to which the lock cylinder is assigned.
