Abstract
Abstract The bayonet coupling is provided with a connecting ring having radial pins for engaging in grooves in a hollow member to provide a loose connection. In addition, a screw-threaded ring is threaded into the connecting ring to move against a shoulder on one hollow member in order to compress a resilient seal ring between the hollow members and thus provide a strong seal-tight connection.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
A bayonet coupling comprising a pair of hollow cylindrical members, one of said members having an axial extension received in a corresponding axial recess in the other of said members, said other member having helical grooves in a periphery thereof, each said groove having a closed end extending at a right angle to a longitudinal axis of said other member; a ring seal between said members; a shoulder on one of said members; an axially movable and rotatable connecting ring engaging said shoulder and having a plurality of radially inwardly projecting elements cooperating with said helical grooves in the other of said members to interconnect said members; and clamping means engaging between said connecting ring and one of said members for moving said members having said shoulder towards said other member to compress said ring seal.
Claim 2
Dependent Claim
136 words
A bayonet coupling comprising a pair of hollow cylindrical members, one of said members having an axial extension received in a corresponding axial recess in the other of said members, said other member having helical grooves in a periphery thereof, each said groove having a closed end extending at a right angle to a longitudinal axis of said other member; a ring seal between said members; a shoulder on one of said members; an axially movable and rotatable connecting ring engaging said shoulder and having a plurality of radially inwardly projecting elements cooperating with said helical grooves in the other of said members to interconnect said members; and clamping means engaging between said connecting ring and one of said members for moving said members having said shoulder towards said other member to compress said ring seal.
Claim 3
Dependent Claim
24 words
A bayonet connection as set forth in claim 1 wherein said clamping means engages between said connecting ring and said member having said shoulder.
Claim 4
Dependent Claim
27 words
A bayonet connection as set forth in claim 2 wherein said clamping means includes a screwthreaded ring threaded into said connecting ring and bearing against said shoulder.
Claim 5
Dependent Claim
21 words
A bayonet connection as set forth in claim 3 which further comprises a spring between said shoulder and said screwthreaded ring.
Claim 6
Dependent Claim
123 words
A bayonet coupling for an electrical plug comprising a pair of hollow cylindrical members, one of said members having an axial extension received in a corresponding axial recess in the other of said members; a ring seal between said members; a shoulder on one of said members; a plurality of helical grooves in the other of said members; a connecting ring bridging over said shoulder at one end and having a plurality of inwardly projecting elements at an opposite end slidably received in said grooves to interconnect said members upon rotation of said ring; and a rotatable clamping ring threadably engaged in said connecting ring and engaging said shoulder for moving said one member towards said other member to compress said ring seal.
Claim 7
Dependent Claim
123 words
A bayonet coupling for an electrical plug comprising a pair of hollow cylindrical members, one of said members having an axial extension received in a corresponding axial recess in the other of said members; a ring seal between said members; a shoulder on one of said members; a plurality of helical grooves in the other of said members; a connecting ring bridging over said shoulder at one end and having a plurality of inwardly projecting elements at an opposite end slidably received in said grooves to interconnect said members upon rotation of said ring; and a rotatable clamping ring threadably engaged in said connecting ring and engaging said shoulder for moving said one member towards said other member to compress said ring seal.
Claim 8
Dependent Claim
21 words
A bayonet coupling as set forth in claim 5 which further comprises a spring between said clamping ring and said shoulder.
