Definitions

  • the invention relates to a universal key, for example a control cabinet key, with a plurality of key arms extending from a central middle part, on which tool heads and / or receiving devices for attaching separate tool heads are arranged.
  • a cross key DE 20 2009 005 858 U1
  • which at the ends of the key arms revolver-like rotatable elements having tool heads of different types and sizes at their opposite ends.
  • a cross key is relatively expensive.
  • the invention has for its object to provide a universal key that allows a multiplication of the type and size of different tool heads with little technical effort.
  • the additional tool heads are displaceable and not rotatable in the inner profile of a stationary tool head and are mounted displaceably and non-rotatably on the outer profile of a stationary tool head.
  • each key arm namely firstly the stationary tool head itself, secondly the outer displaceable tool head and thirdly the displaceable inner auxiliary tool head.
  • the inner and outer auxiliary tool heads are preferably biased toward their active positions by means of a compression spring so that they always assume their operating positions. If, for example, the stationary tool head is in demand, the additional tool heads automatically slide back when they are inserted onto the element to be actuated.
  • the respective pressure spring is expediently abutted against its inner end side.
  • the respective compression spring is appropriate against the seated on the sliding sleeve pin of the pin-slot guide.
  • the pins of the pin-slot guides are preferably designed as dowel pins, on the one hand sit in a bore of the respective additional tool head and on the other hand engage in an arranged in the respective stationary tool head, axially extending longitudinal slot, wherein the slot length limits the displacement path of the respective additional tool head.
  • the inner profile of the stationary tool head can be an internal tappet, a square socket, a hexagon socket or the like.
  • an external striking, an external square, an external hexagon, a double-bit profile or the like may be provided.
  • the inner profile of the sitting on the stationary tool head sliding sleeve is adapted to the outer profile of the stationary tool head.
  • the additional tool heads can have a wide variety of profiles.
  • the outer sliding sleeve can be provided at its active, serving as an additional tool head end with two offset by 90 ° to each other êtvierkantprofile different sizes, whereby the number of possible variations is still increased.
  • a cross-key 1 is shown, are provided on the four outgoing from a central part 2 key arms 3, 4, 5, 6.
  • Each of the four key arms carries at its outer end a stationary tool head, which has the appropriate features for the intended application.
  • the key arm 3 which is provided with an internal tongue 7, carries an inner additional tool head in the form of a triangular sliding sleeve 11, which fits positively into the internal detacher 7 of the key arm 3 and is guided in this longitudinally displaceable. Due to their triangular formation, the sliding sleeve 11 is fixed simultaneously in the direction of rotation.
  • the displacement path of the triangular sliding sleeve 11 is limited between two extreme positions, between an inactive position in which it is displaced into the internal quick-change 7, and an active position in which it protrudes outwards beyond the internal tip 7.
  • a pin-slot guide To limit the displacement of the triangular sliding sleeve 11 is a pin-slot guide.
  • a slot 12 is provided in the key arm 3 on opposite sides, while the triangular sliding sleeve 11 has a continuous transverse bore 13.
  • a clamping pin 14 is inserted, which can slide in the slot 12 in the longitudinal direction of the key arm 3 and thereby the triangular sliding sleeve in the internal striking between the two extreme positions leads.
  • a compression spring 15 is provided between the middle part 2 and the inner end face of the triangular sliding sleeve 11, which presses the triangular sliding sleeve 11 permanently in its active position in which it protrudes from the internal tip 7 of the key arm 3. In this position is serving as an additional tool head triangular sliding sleeve 11 ready. If, on the other hand, the inner trimmer 7 is to be used as a tool head, the key arm 3 is placed on the corresponding workpiece, as a result of which the triangular sliding sleeve 11 automatically shifts against the pressure of the spring 15 inwards into its inactive position.
  • the key arm 4 which is formed with a stationary tool head in the form of a double-bit profile 8, is combined with an outer sliding sleeve 16.
  • the sliding sleeve 16 is mounted longitudinally displaceable on the key arm 4 and secured against rotation due to the double-bit profile 8. Also, the sliding sleeve 16 is back and forth between two extreme positions, the limitation of the sliding path by means provided in the key arm 4 longitudinal slots 17, in which a clamping pin 18 is guided, is effected.
  • the clamping pin 18 extends through a provided in the outer sliding sleeve 16 transverse bore 19 and in the longitudinal slots 17 therethrough.
  • a compression spring 15a is provided, which always holds the outer sliding sleeve 16 in its active position.
  • Fig. 2 shows, the sliding sleeve 16 at its working end an inner profile 20, which has two mutually offset by 90 ° réellevierkantprofile different sizes.
  • a longitudinally displaceable inner part 21 is provided in a similar manner as in the key arm 3, the stroke limitation by means provided in the key arm 5 on opposite sides longitudinal slots 22nd and a through this and a provided in the inner part 21 transverse bore 24 extending clamping pin 23 is effected.
  • the inner part 21 is loaded by a compression spring 25 in this embodiment, which is supported against the bottom of the inner part 21 and this always presses in its active position.
  • the sliding sleeve 26 can be pressed by means of a compression spring, not shown in the drawing into its working position, wherein the compression spring between the middle part 2 and the clamping pin 28 may be arranged.
  • the key arm 6, the stationary tool head according to the drawing is an internal clockwise, is used in the illustrated embodiment for receiving an adapter 30, in which a bit with any working end, such as a screwdriver bit can be inserted into a corresponding receiving opening 31.
  • the universal key can have twelve different tool heads to unify.
