Definitions

  • the present invention relates to a lock mechanism and more particularly to a lock mechanism which has a large motion but minimal free-play.
  • locks are required which operate output members having relatively large movements. Often this results in quite large forces needing to be generated or transferred within the lock mechanism.
  • One such instance is the locks which are used for PVC windows and/or doors where the complete lock mechanism fits inside the frame of the window or door.
  • Such mechanisms also often have long bars so as to provide for a plurality of locking points along the length of one of the elements of the door or window.
  • Such mechanisms have a number of constraining features one of which is that the complete mechanism must be located within the thickness of the door or window frame and the other is that it would be advantageous to provide a mechanism which is capable of being adapted to a number of different situations such as a handle on only one side, handles on both sides, or a handle on one side which is not connected to the handle on the other side of the window or door.
  • FIG. 1 shows a mechanism in which the originating force is provided by a rotable lever 10 which is mounted on a square section shaft 11 which in turn is capable of rotation by a user operating a handle or knob.
  • the free end of the lever 10 is linked to an end 12a of an intermediate member 12 by means of a pin and slot arrangement which provides for true reciprocation of the intermediate member 12 as the arm 10 rotates.
  • the other end 12b of the member 12 is linked to an output rod 13 by a specially constructed linkage which will be described in more detail later.
  • the output rod 13 transmits the reciprocal motion of the intermediate member 12 to an output linkage or mechanism which, depending on the use to which the lock is to be put, may amplify the motion of the member 13.
  • the intermediate member 12 is linked to the output rod 13 by means of a controlled linkage.
  • the controlled linkage comprises a pivotally mounted rocker element 15 on the end 12b of the member 12 which engages with the output member 13 at two pivot points 15a and 15b.
  • the main rocker pivot 15c is not in line with the pivot points 15a and 15b.
  • the pivot points 15a and 15b are not fixed to the output member 13. Rather, they constitute additional axis about which the rocker 15 may pivot depending on the constraints placed upon the intermediate member 12. This will now be described in more detail.
  • pivot points 15a and 15b are in fact constituted by circular cross-section pins which are received in arcuate recesses in the ends of a slot 18 in the output member 13. If a force is applied to the main pivot 15c in a direction such that the pins 15a and 15b are held in the recesses, then any linear movement of the intermediate member 12 parallel to the length of the slot in the output member 13 will result in reciprocation of the output member 13. Consequently, it will be apparent that any rotation of the handle or knob attached to the square section shaft 11 will result in reciprocation of the output member 13 in this condition.
  • the pin 15b is provided so as to enable the output shaft to be moved either upwards from the position shown in Fig. 1 or additionally in a downwards direction from the position shown in Fig. 1 .
  • the link 21 is pivotally moveable about a fixed pivot point 25 and the free end of the link 22 is coupled to the intermediate member 12 by means of a pin 28 fixed to the free end of the link 22 and received in a slot 30 in the intermediate member 12.
  • the pin 28 is constrained to move in a direction transverse to the direction of reciprocation of the output member 13 by being received in a transversely directed slot provided in a fixed part associated with the overall lock mechanism.
  • the device 20 is in the form of an piezo ceramic actuator such as the one sold as the AL2 by Servocell Limited which can be electrically controlled to either permit collapsing of the linkage 21,22 or inhibit collapsing of the linkage 21,22 by contacting a suitable part of the linkage.
  • this arrangement is bi-directional as long as one dimensions and positions the slot 30 appropriately and biasing of the mechanism can also be provided in this condition also.
  • the above mechanism is the basis mechanism which can be utilised in situations when a handle need be provided on only one side of the door or window or where it is appropriate to have single solid shaft 11 with handles on both the inside and outside. It is possible to modify the above construction so as to provide for the situation where one wishes to have a handle on the inside which is not rigidly coupled to handle on the outside so as to permit a number of different operational facilities. This is achieved by means of utilising a common output member 13 which has an increased dimension into the thickness of the paper and providing two intermediate members 12 and control linkages 21,22 with associated electrical control, if desired. Each of the intermediate members 12 would be connected to its own shaft 11 and handle or knob.
