Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
199 words
A coupling of the ball-and-socket joint type 115 between two objects, comprising coupling members adapted to be connected to each said object, wherein one of said coupling members comprises on the one hand a spherical socket and .) on the other hand a ball with a radius smaller than 120 that of the socket, the central axis of the ball coinciding with that of the socket so that a gap exists between the socket and ball with a width corresponding to the difference between the internal radius of the socket and the external 125 radius of the ball; the other said coupling member comprising a spherical shell disposed between said socket and ball and having outer and inner - radii substantially the same as the radii of said socket and ball so that said shell can completely fill the gap between the socket and ball and can be displaced in various directions by sliding in said gap; gripping means being provided to urge said ball and said socket towards one another so that the said shell can be locked in the desired position whereby the two coupling members are locked in the desired position in relation to one another.,
Claim 2
Dependent Claim
199 words
A coupling of the ball-and-socket joint type 115 between two objects, comprising coupling members adapted to be connected to each said object, wherein one of said coupling members comprises on the one hand a spherical socket and .) on the other hand a ball with a radius smaller than 120 that of the socket, the central axis of the ball coinciding with that of the socket so that a gap exists between the socket and ball with a width corresponding to the difference between the internal radius of the socket and the external 125 radius of the ball; the other said coupling member comprising a spherical shell disposed between said socket and ball and having outer and inner - radii substantially the same as the radii of said socket and ball so that said shell can completely fill the gap between the socket and ball and can be displaced in various directions by sliding in said gap; gripping means being provided to urge said ball and said socket towards one another so that the said shell can be locked in the desired position whereby the two coupling members are locked in the desired position in relation to one another.,
Claim 3
Dependent Claim
48 words
A coupling as claimed in claim 1, wherein said gripping means comprise a locking pin which extends between the socket and the ball and which is adapted to be able to press the socket and the ball towards one another with spring force, locking said spherical shell therebetween.
Claim 4
Dependent Claim
52 words
A coupling as claimed in claim 2 wherein the spring force of said gripping means is developed by at least one spring on the side of the socket and/or the ball remote from said gap, said at least one spring being gripped between said side and a stop on the locking pin.
Claim 5
Dependent Claim
24 words
A coupling according to claim 3, wherein said at least one spring comprises a stack of dished washers on the inside of said ball.
Claim 6
Dependent Claim
37 words
A coupling as claimed in claim 1, 2, 3 or 4, and including disengagement means to release the coupling when fresh positions are to be assumed, said disengagement means being a unit independent of said gripping means.
Claim 7
Dependent Claim
69 words
A coupling as claimed in claim 5 when appendant to claim 3 or 4, wherein said disengagement means comprises a tightening element fixed to said socket or said ball against which said at least one spring is gripped, and said tightening element is adapted to be able to compress said at least one spring to a sufficent extent to cancel the gripping force so that the coupling is released.
Claim 8
Dependent Claim
16 words
A coupling as claimed in claim 6, wherein said disengagement means is adapted to be remote-controlled.
Claim 9
Dependent Claim
88 words
A coupling as claimed in claim 2 or in any one of claims 3 to 7 when appendant thereto, wherein the locking pin extends through axial holes in the socket and the ball and through an opening in the spherical shell which opening is larger than the pin and permits displacement of the shell in relation to the socket and the ball without hindering the locking pin, and said at least one spring is disposed in a cavity in the ball on one end of the locking pin.
Claim 10
Dependent Claim
43 words
A coupling as claimed in claim 8, wherein the tightening element is disposed axially in relation to tile locking pin and has a piston rod adapted to bear against the said one end of the locking pin in said cavity in the ball.
Claim 11
Dependent Claim
41 words
A coupling as claimed in any one of claims 1 to 9, wherein a return member is provided to return the said coupling members to a position of symmetry and to damp movements of the coupling when said coupling is disengaged.
Claim 12
Dependent Claim
35 words
A coupling as claimed in claim 10, wherein: said return member comprises one or more flexible elements between the back of the joint ball and a body to which the spherical shell is connected. 4
Claim 13
Dependent Claim
25 words
A coupling of the ball-and-socket type constructed and adapted to operate substantially as hereinbefore described with reference to, and as illustrated in, the accompanying drawings.
Claim 14
Dependent Claim
25 words
A coupling of the ball-and-socket type constructed and adapted to operate substantially as hereinbefore described with reference to, and as illustrated in, the accompanying drawings.
Claim 15
Dependent Claim
42 words
A coupling as claimed in any one of the preceding claims wherein said hemispherical shell GB 2 024 926 A 4 is connected to the body of a vehicle and said ball and socket are connected to a seat of the vehicle.
Claim 16
Dependent Claim
54 words
A coupling as claimed in claim 13, wherein said hemispherical shell is secured to raisable pillar adjustably mounted on the floor of said vehicle.
