  • the controller 60 has a signal receiver and decoding microprocessor that is adapted to receive an external signal carrying an external access code, to compare it to a programmed access code, and to actuate the solenoid 62.
  • the electronic controller has a microphone 66 for receiving an external coded vibration signal transmitted by an electronic key with impact impeller head, of a kind described in US 6,411,195 to the same inventor, the content of which is incorporated herein by reference.

  • Solenoid 62 has an anchor 72 connected to the latch 70 so as to move the latter, engaging or releasing the clutch pin 40.
  • the mounting member 4 is, in this embodiment, a disc-shaped plate, with a generally rectangular central opening 80 and is constructed out of two parts 82 and 84 connected by screws 86. As is seen in the view of Fig. 6A, the mounting member plate 4 is tightly mounted on a standard gas filling port 89 and is arrested from detachment by the wider opening 90. Opening 90 can be sealed by closure cap 92.
  • the mounting member 4 as can be seen in Figs. 6A and 6B, which may be made of metal or plastic, has three openings 102, each comprising a wider bore 104 and angularly oriented narrower channel 106.
  • Bore 104 has a diameter that permits pin head 18 to pass through.
  • the width of channel 106 is such so as to allow stem 20 to pass therethrough but not the pin head 18.
  • the distal end of the channel 106 has a stepped recess 108 (see Fig. 6B) of the same diameter of bore 104 and is thus adapted to receive the pin head 18, which once in the recess 108 is arrested from axial movement in the direction toward the protective cover unit 2 by shoulders 110.
  • the protective co ⁇ er unit 2 and the mounting member plate 4 constitute a bayonet lock which can be locked by axial insertion of the pins 16 into bores 104 of the mounting member 4, then turning the protective cover unit 2 by about 20°, the stems 20 of the pins 16 thus sliding in channels 106.

  • FIGs. 3A and 3B the bayonet lock between the protective cover unit 2 and the mounting member plate 4 is shown in the closed and locked state, with the bolt head 18 sunken in the recess 108, resting against the recess's shoulders 110.
  • axial rotation of the protective cover unit with respect to the mounting member is impaired (see also Fig.S).

  • the head 46 of pin 40 abuts the sliding cover 14, the skirt portion 15 of which bears on mounting member plate 4, the housing 10 ⁇ vith pins 16 cannot be axially displaced.
  • trie controller 60 Upon receiving a correct access code, trie controller 60 actuates the solenoid 62 to push the latch 70 and disengage the groove 42, as seen in Figs. 2 A and 2B. As long as not receiving another actuating signal, the bi-stable solenoid remains in this position. Once disengaged as aforementioned, the housing 10 can now be pushed in the direction of the mounting member plate 4, and since skirt 15 of inner cover 14 continues to bear against mounting member 4, this axial displacement, represented by the downwards arrow in Fig. 2B, causes the head 18 to pop out of the recess 108. The protective cover unit 2 can now be turned so that the pins 16 slide towards the bores 104 and once there the protective cover unit 2 can be detached axially from the mounting member 4. The gas port can now be freely accessed.
  • the protective cover unit 2 is brought into engagement with the mounting member plate 4 with pins 16 aligned with the bores 104, pushed axially and turned.
  • the springs 32 push against the sliding cover 14, the skirt portion 15 of which bears against mounting member 4, whereby the protective cover unit with the pins is pushed away from the mounting member plate 4 and the bolt heads IS sink into the recesses 108.
  • a locking coded signal received by the controller 26 will actuate the solenoid 62 to pull the latch 70 back and engage the annular groove 42 of clutch pin 40, thereby locking the gas valve lock.
  • the skirt 11 of protective cover unit 10 extends over the mounting member thus blocking access to screws 86 (not seen in this figure).
  • the controller receiver and the signal transmission may be implemented in a number of other ways known in the art, for example by radio waves, infrared or visible light.
  • the bayonet lock may be implemented in different ways, for example with radial lugs or lugs fixed to the mounting plate while profiled cuts (bores) may be in the protective cover unit.
  • valve lock assembly of the invention is relatively easy for mounting, relatively compact, and yet very robust and resistant to tempering.
  • gas valve lock may be used with slight modifications for locking any valved container for liquids, gases, powders or other flowable materials.
