Fluid operated lock

Claim 2

A fluid lock construction, comprising a plurality of ganged board-like elements, each respectively containing a portion of a fluid circuit, said elements forming with the other elements in said ganged construction a connective fluid circuit path, means supported by said elements for altering the continuity of said connective fluid circuit path, and locking means operatively connected to said fluid circuit and responsive to the continuity of the fluid path.

Claim 3

The lock construction of claim 1, whereiN said connective path is a series circuit path.

Claim 4

The lock construction of claim 1, wherein said connective path is a parallel circuit path.

Claim 5

The lock construction of claim 1, wherein said means for altering said fluid circuit path are movable members responsively movable with respect to a position of an inserted key.

Claim 6

The lock construction of claim 4, wherein each board-like element contains at least one movable member, and wherein each of said members is movably responsive to an individual tooth on said key.

Claim 7

The lock construction of claim 4, wherein said movable members each contain a portion of the fluid circuit path, and the movement of said members alters the fluid circuit path within each board-like element, and consequently changes the fluid circuit path for the entire lock construction.

Claim 8

The lock construction of claim 5, wherein said movable members are rotatively movable in response to insertion and turning of said key and the presence of an individual tooth of said key being at an insertable position within said member.

Claim 9

The lock construction of claim 5, wherein said movable members are ganged with other of said members by virtue of being disposed upon said board-like elements, each of said movable members having an insert portion for a key, and being thus ganged said insert portions form with the other insert portions a keyway for said key.

Claim 10

The lock construction of claim 8, wherein there are two movable members for each board-like element.

Claim 11

A fluid lock, comprising: A. structural means defining a fluid path; B. means for supplying fluid to said fluid path; C. means supported by the structural means for altering the continuity of said fluid path; and D. locking means operatively connected to said structural means and being operatively responsive to the continuity of said fluid path.

Claim 12

A fluid lock, comprising: A. structural means defining a fluid path; B. means for supplying fluid to said fluid path; C. means supported by the structural means for altering the continuity of said fluid path; and D. locking means operatively connected to said structural means and being operatively responsive to the continuity of said fluid path.

Claim 13

The fluid lock of claim 10, wherein said means for altering the continuity of said fluid path comprises a plurality of ganged elements having a keyway aperture for receiving a key.

Claim 14

The fluid lock of claim 10, wherein said means for altering the fluid path comprises a plurality of paired rotative switching members, each disposed within, and forming part of said fluid path.

Claim 15

A fluid lock construction, comprising: a first plurality of ganged switches being ganged back-to-back so as to form a keyway for receiving a first insertable key-like element, said first key-like element actuating at least one of said first plurality of switches when inserted therein; a second plurality of ganged switches being ganged back-to-back so as to form a keyway for receiving a second insertable key-like element, said second key-like element actuating at least one of said second plurality of switches when inserted therein; and interconnecting fluid circuit means for interconnecting said first and second plurality of switches to form a fluid circuit path whose continuity is dependent upon the actuation of certain of said first and second switches.

Claim 16

A fluid lock construction, comprising: a first plurality of ganged switches being ganged back-to-back so as to form a keyway for receiving a first insertable key-like element, said first key-like element actuating at least one of said first plurality of switches when inserted therein; a second plurality of ganged switches being ganged back-to-back so as to form a keyway for receiving a second insertable key-like element, said second key-like element actuating at least one of said second plurality of switches when inserted therein; and interconnecting fluid circuit means for interconnecting said first and second plurality of switches to form a fluid circuit path whose continuity is dependent upon the actuation of certain of said first and second switches.

Claim 17

The fluid lock construction of claim 13, wherein said fluid circuit is a series circuit.

Claim 18

The fluid lock construction of claim 13, wherein said fluid circuit is a parallel circuit.
