As seen in Fig. 1C, bottom end wall surfaces 120 and 122 include respective semi-circular cut-out portions 124 and 126 for placement of hinged protective cover assembly 102 over a valve assembly of a gas canister or a fluid container, as described further hereinbelow with reference to Figs. 3A - 3B and 6A - 6B. Elements 112 and 114 are provided with a respective generally cylindrical locking shaft receiving portions 132 and 134, which are arranged to be coaxial when the cover assembly 102 is in its closed operative orientation as shown in Figs. IA - 1C. Elements 112 and 114 are preferably mutually pivotably mounted about an axis 136 by a hinge 138 fixed to top end wall surfaces 116 and 118. The remote monitoring unit 104 and the locking shaft 106, which is fixedly mounted thereto, are commercially available from Hi-G-Tek Ltd. of Israel, and are designated preferably by one of the following model designations: IG-LK-40-433 and IG-LK-40-916. Locking shaft receiving portions 132 and 134 are configured to slidably receive locking shaft 106.
Key-operable locking unit 108 may be any suitable key-operated lock and is preferably a conventional pin lock, which is commercially available from MuI-T- Lock Ltd. of Yavne, Israel.
Locking shaft 106 is configured to extend through locking shaft receiving portions 132 and 134 and through an aperture 139 in key-operable locking unit 108 into lockable engagement with key-operable locking unit 108. Remote monitoring unit 104 is operative such that unlocking of key-operable locking unit 108 from locking shaft 106 or unauthorized disengagement of cover assembly 102, such as in an unauthorized attempt to remove cover assembly 102 from the locking system or otherwise tamper with the locking system, will be monitored and wirelessly notified to a monitoring center (not shown).
Reference is now made to Fig. 2, which is a simplified pictorial illustration of protective cover assembly 102 of lock assembly 100 of Figs. IA - 1C in an open operative orientation, following placement thereof over a valve of a gas canister, and to Figs. 3A and 3B, which are, respectively, a simplified pictorial illustration and a sectional illustration of protective cover assembly 102 of lock assembly 100 of Figs. IA - 1C in a closed operative orientation, following placement thereof over a valve of a gas canister.
The initial engagement of cover assembly 102 with a valve assembly 140 of a gas canister 142 is seen in Fig. 2. Figs 3A and 3B show cover assembly 102 in a closed operative orientation such that semi-circular cut-out portions 124 and 126 of bottom end wall surfaces 120 and 122 engage a neck portion 144 of valve assembly 140 and prevent unauthorized lifting and removal of cover assembly 102 from valve assembly 140.
Preferably, when in a closed orientation as seen in Figs. 3A & 3B, cover assembly 102 is operative to cover a flow control knob 146 and a threaded connection portion 148 of the valve assembly 140 and thus to prevent unauthorized access thereto and removal thereof and to monitor authorized access thereto .
Reference is now made to Fig. 4, which shows lock assembly 100 of Figs. IA - 1C in remotely monitorable locked engagement with valve assembly 140 of gas canister 142. Locking shaft 106 extends through coaxial locking shaft receiving portions 132 and 134, fixed to elements 112 and 114 of cover assembly 102, which are in a closed operative location. Locking unit 108 prevents disengagement of locking shaft 106 from receiving portions 132 and 134 and thus prevents opening of cover assembly 102 and disengagement thereof from the valve assembly 140.
Remote monitoring unit 104 communicates, preferably via a wireless communication link, such as by RP communication or any other suitable communication, with a remote communication device 150, for providing monitorable indications both of tampering and of authorized unlocking of locking unit 108 from locking shaft 106. Remote communication device 150 is preferably operative to communicate with a computer 152 or other remotely located device, typically via a network, such as the Internet.
Reference is now made to Fig. 5, which is a simplified pictorial illustration of protective cover assembly 102 of lock assembly 100 of Figs. IA - 1C in an open operative orientation, following placement thereof over a valve assembly of a fluid container, and to Figs. 6 A and 6B, which are, respectively, a simplified pictorial illustration and a sectional illustration of lock assembly 100 of Figs. IA - 1C in remotely monitorable locked engagement with the valve assembly of the fluid container.
Fig. 5 shows the initial engagement of cover assembly 102 with a valve assembly 160 of a fluid container 162. Figs 6 A and 6B show the cover assembly 102 in a closed and locked operative orientation such that semi-circular cut-out portions 124 and 126 of bottom end wall surfaces 120 and 122 engage a neck portion 164 of valve assembly 160 and prevent unauthorized lifting and removal of cover assembly 102 from valve assembly 160. Preferably, when in a closed orientation as seen in Figs. 6A & 6B, cover assembly 102 is operative to cover a flow control knob 166 and a threaded connection portion 168 of the valve assembly 160 and thus to prevent unauthorized access thereto and removal thereof and to monitor authorized access thereto.
As seen in Fig. 6B, protective cover assembly 102 is operative to cover the entire valve assembly 160 of fluid container 162, to prevent unauthorized removal thereof. Reference is now made to Fig. 7, which shows lock assembly of Figs. IA - 1C in remotely monitorable locked engagement with the valve assembly 160 of the fluid container 162. Locking shaft 106 extends through coaxial locking shaft receiving portions 132 and 134, fixed to elements 112 and 114 of cover assembly 102, which are in a closed operative location. Locking unit 108 prevents disengagement of locking shaft 106 from receiving portions 132 and 134 and thus prevents opening of cover assembly 102 and disengagement thereof from the valve assembly 160.
