Abstract
Abstract An angle joint or swivel joint, consisting principally of a ball and socket wherein the ball socket is constructed preferably of a tough plastic. The ball socket has a body which is bifurcated by a central slot, thereby permitting elastic yielding of the two constituent jaws when the spherical end of the ball pin is emplaced in the ball socket. In order to prevent subsequent relative movement of the two parts of the ball socket, the body of the ball socket has a transverse profiled channel which receives a mating locking bolt having the same profile. When the locking bolt has been driven home, the two previously yielding jaws are prevented from further relative motion, thereby imprisoning the ball in the socket. A cut-out in one of the jaws permits preassembly without locking and a protrusion of the locking bolt makes possible subsequent removal and disassembly.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
An angle joint including a ball socket and a ball pin, the ball of said ball pin residing in the ball socket, said ball socket having a body which is bifurcated by a central slot, thereby defining two elastically yielding jaws, and further including a locking device for preventing relative motion of said jaws after emplacement of said ball in said ball socket, and wherein, according to the invention, said ball socket is provided with a transverse channel extending normally with respect to said central slot, said transverse channel having respective channel portions which lie in said jaws and defining a cross section profile and wherein there is provided a locking bolt being received in said transverse channel to thereby lock together said jaws and wherein there is provided in one of said channel portions a cut-out portion which opens from said one channel portion to said central slot.
Claim 2
Dependent Claim
149 words
An angle joint including a ball socket and a ball pin, the ball of said ball pin residing in the ball socket, said ball socket having a body which is bifurcated by a central slot, thereby defining two elastically yielding jaws, and further including a locking device for preventing relative motion of said jaws after emplacement of said ball in said ball socket, and wherein, according to the invention, said ball socket is provided with a transverse channel extending normally with respect to said central slot, said transverse channel having respective channel portions which lie in said jaws and defining a cross section profile and wherein there is provided a locking bolt being received in said transverse channel to thereby lock together said jaws and wherein there is provided in one of said channel portions a cut-out portion which opens from said one channel portion to said central slot.
Claim 3
Dependent Claim
20 words
An angle joint according to claim 1, wherein said cross-sectional profile is substantially similar to a pair of opposing T's.
Claim 4
Dependent Claim
23 words
An angle joint according to claim 1, wherein said locking bolt has a protrusion substantially corresponding to the shape of said cut-out portion.
Claim 5
Dependent Claim
22 words
An angle joint according to claim 1, wherein said locking bolt has an extended nose overlapping a portion of said central slot.
Claim 6
Dependent Claim
19 words
An angle joint according to claim 1, wherein the cross-sectional profile of said slot is constant over its length.
Claim 7
Dependent Claim
32 words
An angle joint according to claim 1, wherein the cross-sectional profile of said locking bolt is reduced in size over its length, thereby imparting a slightly conical configuration to said locking bolt.
Claim 8
Dependent Claim
17 words
An angle joint according to claim 1, wherein the blind end of said central slot is rounded.
Claim 9
Dependent Claim
20 words
An angle joint according to claim 1, wherein said ball socket is constructed of a tough elastic injection moldable plastic.
