Abstract
Abstract A pivotal mounting arrangement, which may be used for mounting a lamp on a vehicle body, comprises a plastics body having an integral boss provided with a hexagonal inwardly tapering recess therein. A socket element formed from a spring steel sheet has a cup-shaped central portion and six arms extending integrally upwardly therefrom. Outwardly projecting portions extend from the arm and the distance between opposed portions is greater than the corresponding dimension of the recess. A ball integral with one end of a screw-threaded rod is engaged in the socket element before the latter is forced fully into the recess. When disposed in position in the recess, the arms of the socket element are deformed inwardly and hold the ball captive while allowing same to rotate relative to the socket element. This arrangement permits the boss to be formed out of a material which can be relatively rigid because the boss itself need not be resilient.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
A pivotal mounting arrangement comprising a member having a recess therein, and a socket element mounted in said recess, said socket element being formed of a resilient material, being adapted to receive and, when mounted in the recess, to hold a ball therein and having at least one outwardly projecting portion which engages against the wall of said recess and opposes withdrawal of said socket element from said recess.
Claim 2
Dependent Claim
69 words
A pivotal mounting arrangement comprising a member having a recess therein, and a socket element mounted in said recess, said socket element being formed of a resilient material, being adapted to receive and, when mounted in the recess, to hold a ball therein and having at least one outwardly projecting portion which engages against the wall of said recess and opposes withdrawal of said socket element from said recess.
Claim 3
Dependent Claim
67 words
The arrangement according to claim 1, wherein said socket element comprises a curved base portion and a plurality of arms which extend integrally away from said curved base portion so that said curved base portion and said arms together define a socket for receiving said ball, said arms having ends thereof remote from said base portion outwardly turned to define a plurality of said outwardly projecting portions.
Claim 4
Dependent Claim
32 words
The arrangement according to claim 2, wherein said recess has a polygonal cross-section and the number of said arms of said socket element corresponds to the number of sides of the polygon.
Claim 5
Dependent Claim
13 words
The arrangement according to claim 3, wherein said recess is of hexagonal cross-section.
Claim 6
Dependent Claim
16 words
The arrangement according to claim 2, wherein each of said arms is linear across its width.
Claim 7
Dependent Claim
48 words
The arrangement according to claim 1, wherein the width of said socket element across mutually opposed outwardly projecting portions is greater than the corresponding dimension of said recess so that said projecting portions have to be deformed inwardly in order to insert said socket element into said recess.
Claim 8
Dependent Claim
60 words
The arrangement according to claim 2, wherein said arms define a substantially non re-entrant socket before said socket element is inserted into said recess and, when said socket element is inserted into said recess, said arms are deformed inwardly by engagement of said outwardly projecting portions with said wall of said recess so as to define a generally part-spherical recess.
Claim 9
Dependent Claim
16 words
The arrangement according to claim 1, including said ball which is mounted in said socket element.
Claim 10
Dependent Claim
16 words
The arrangement according to claim 1, wherein said outwardly projecting portion tapers substantially to a point.
