Definitions

  • the invention relates to a lock element with a lock body, a lock element which can be rotated relative to the lock body and an actuation element which can be coupled to the lock element and which can be rotated relative to the lock body.
  • Such lock elements are used, for example, in conventional mortise locks, in which a profile cylinder serves as a lock body and a door handle or door knob as an actuating element.
  • a profile cylinder serves as a lock body and a door handle or door knob as an actuating element.
  • an actuator after installation of the lock body in the door must be retrofitted.
  • an actuating element embodied, for example, as a door knob, so that comparatively little space is available for fastening the actuating element to the lock body.
  • a common solution known from the prior art suggests mounting at least one of the two actuators on a shaft extending through the door lock and by means of a fastener element acting radially on the shaft, e.g. to fix a threaded pin.
  • this solution is optically unsatisfactory because the fastener is visible on the outside of the actuator.
  • a solid shaft is required for a sufficiently stable attachment, which limits the space available for mechanical and electronic components space.
  • assembly and disassembly of an attachable in this way actuator are relatively expensive.
  • a lock element which can be opened from one side of the lock with a key and from the other side of the lock with a rotary handle.
  • the rotary handle is rotatably mounted with a shaft in the associated lock body and axially locked by means of a fixing element.
  • the seated in the lock body fixing protrudes for this purpose in a formed on the shaft circumferential groove.
  • the GB 853 801 A discloses a door handle which is attachable with a hollow shaft portion on a through the lock nut inserted square bar. The fixation takes place via a locking pin mounted in a square bar, which springs in spring into a hole in the door handle.
  • Object of the present invention is to provide a lock element of the type mentioned, in which an actuator in a simple and space-saving manner is releasably fastened.
  • the lock element in this case has a protruding into the lock body cavity, in which the actuating element with a cylindrical attachment portion is releasably fastened.
  • the cylindrical attachment portion of the actuating element has on the outside a circumferential groove which can be latched with a latching element, which is guided radially to the axis of the cylindrical mounting portion slidably in the lock body and acted upon by a spring in the direction of the groove of the actuating element.
  • the actuating element is thus secured by the latching of the groove with the corresponding locking element against axial displacement.
  • both the latching element and the lock body each have a bore, wherein the two bores have at least substantially the same diameter and extend parallel to the axis of the cylindrical attachment portion.
  • the two holes are arranged so that the lock body-side bore extending from the end of the lock body to which the actuator is fastened, up to the bore of the lock body mounted in the lock element, and that the two holes are aligned with each other in a compressed spring and overlap partially with a relaxed spring. With compressed spring are the two So drilling axially behind each other.
  • Such an arrangement allows a release of the locking of the locking element with the actuating element by means of a special eccentric tool.
  • Such a tool resembles a screwdriver with a handle and a round metal rod attached thereto.
  • the tip of this metal rod forms a cylindrical extension whose cross-section is smaller than that of the metal rod, and which is arranged at the front end of the metal rod eccentrically on this.
  • the two holes overlap only partially and an eccentric can be introduced with its cylindrical extension through the lock body side bore in the overlap region of the hole provided in the locking element.
  • the cylindrical attachment portion may have at its protruding into the lock body end a conical taper, which allows a displacement of the locking element against the spring tension during insertion of the actuating element into the cavity of the lock body. If the lock body is already mounted in a door lock, the actuator can thus be easily attached to the lock element.
  • the force applied during insertion force through the inclined surface on the tapered mounting portion in a radially extending force which can compress the spring converted. If the actuating element is inserted far enough into the cavity, its circumferential groove engages with the locking element, wherein this is pressed by the spring in the direction of the groove.
  • the actuator can therefore be attached by simply plugging, without the need for a tool would be necessary, at the same time assembly errors are reliably avoided.
  • the latching element may be guided along a running inside the lock body, in particular linear guideway, wherein its movement is limited in two opposite directions extending radially to the axis of the cylindrical mounting portion directions by means of stop elements.
  • the latching element is thus accommodated in a space-saving manner relative to the interior of the fastening element and the travel by which the latching element is displaceable radially relative to the axis of the cylindrical fastening section is limited by means of the stop elements.
  • stop elements for example, provided in the locking element slot and provided in the lock body pin, which extends through the slot serve.
  • Such a construction is easy to implement and also durable and maintenance-free.
  • the spring which acts on the latching element in the direction of the groove of the fastening section, may be arranged in a recess of the latching element extending radially to the axis of the cylindrical fastening section.
  • the above-mentioned pin which serves as a stop element, can form a supporting element for the spring with an area extending into this recess.
  • the recess in which the spring is arranged may be open on the surface of the lock body, but also a chamber-like closed recess is conceivable.
  • the diameter of the two holes extending parallel to the axis of the cylindrical attachment portion may be between 2 mm and 5 mm, in particular approximately 3 mm. With a relaxed spring, the two holes overlap preferably about half of their diameter. In this way, an optimal force transmission when attaching an eccentric tool for releasing the locking is achieved at a reasonable engagement depth between locking element and groove.
  • the actuator is in the manner explained relatively easily detachable from the lock body, nevertheless, the fact that a special tool is necessary to release the locking, a certain protection against improper removal of the actuator. It is particularly advantageous that the actuator can be mounted and dismantled as often as desired, without the lock element is damaged or without signs of wear occur.
  • the lock element according to the invention can have a shaft rotatably mounted centrally in the cavity of the lock body, which shaft is non-rotatably connected at one end to a second actuation element, whereas the first actuation element has a receptacle for the other end of the shaft.
  • additional coupling elements it is possible due to the existing shaft to produce a frictional connection between the two actuators.
  • the shaft according to the invention is not used for fixing the first actuating element, it can also be designed as a hollow shaft, whereby additional space for electronic components, cables or the like is available.
  • the attachment portion may have at its end projecting into the cavity of the lock body end face a first force transmission element, which is engageable with a corresponding thereto second power transmission element into engagement, which in turn is rotatably coupled to the closing element.
  • a frictional connection between the releasably secured mounting portion and the closing element can be made, so that the closing element rotates upon actuation of the actuating element.
  • a force transmission elements for example, a radially extending groove and at least one corresponding projection are possible.
  • the lock body may for example have the shape of a standard commercial profile cylinder. Such a lock body can, without additional adapters are necessary to be used in conventional door locks with standardized dimensions.
  • Such a molded lock body consists of an upper portion with a cylindrical cross section and a lower portion with an elongated cross section.
  • the guided in the lower portion of the lock body portion of the locking element must be narrower than the lower portion of the lock body in a direction perpendicular to the longitudinal center plane of the lock member direction.
