Abstract
Abstract A hinge for pivotally connecting two components, the hinge being in the form of two pivotally inter-connected leaves and a casing, one leaf being arranged to be secured to one component and the casing being arranged to be secured to the other component. The casing provides a socket having opposed walls between which the other leaf can slide, one of the walls of the casing and the other leaf having complementary formations which interengage with a snap action to hold the other leaf in the socket and the one wall of the casing being arranged to lie between the other leaf and the other component when the hinge is in use.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
110 words
A hinge for pivotally connecting two components, said hinge comprising two pivotally inter-connected leaves and a casing, one leaf being arranged to be secured to one component, the casing being arranged to be secured to the other component and to provide a socket having opposed walls between which the other leaf can slide, one of the walls and said other leaf having complementary formations which interengage with a snap action to hold said other leaf in the socket when said leaf has entered the socket to a predetermined extent, said one wall being arranged to lie between said other leaf and the other component when the hinge is in use.
Claim 2
Dependent Claim
110 words
A hinge for pivotally connecting two components, said hinge comprising two pivotally inter-connected leaves and a casing, one leaf being arranged to be secured to one component, the casing being arranged to be secured to the other component and to provide a socket having opposed walls between which the other leaf can slide, one of the walls and said other leaf having complementary formations which interengage with a snap action to hold said other leaf in the socket when said leaf has entered the socket to a predetermined extent, said one wall being arranged to lie between said other leaf and the other component when the hinge is in use.
Claim 3
Dependent Claim
25 words
A hinge according to claim 1 in which the formations comprise a resilient projection on said one wall and an aperture in said other leaf.
Claim 4
Dependent Claim
31 words
A hinge according to claim 2 in which the resilient projection is arranged to be disengageable from the aperture in order to allow removal of said other leaf from the socket.
Claim 5
Dependent Claim
55 words
A hinge according to claim 3 in which the other wall of the casing is apertured at a position overlying the resilient projection in order to allow a tool to be inserted through the aperture in the other wall to depress the resilient projection to allow disengagement of the aperture in said other leaf member.
Claim 6
Dependent Claim
65 words
A hinge according to claim 4 in which the free end of said other leaf is provided with a slot in alignment with the aperture in the other wall and which extends from the aperture in the other leaf to the free end thereof thus allowing the resilient projection to be depressed by the tool throughout the removal of the other leaf from the socket.
Claim 7
Dependent Claim
47 words
A hinge according to claim 4 in which said other leaf is arranged to be supported by the other wall of the casing against movement away from said other wall in directions substantially perpendicular thereto when said other leaf has entered the socket to said predetermined extent.
Claim 8
Dependent Claim
38 words
A hinge according to claim 6 in which said other leaf is provided with a formation which projects therefrom and is arranged to engage the other wall in order to support said other leaf on the other wall.
Claim 9
Dependent Claim
40 words
A hinge according to claim 6 in which the other wall is provided with a pair of lugs arranged to extend between said other leaf and said one wall in order to support said other leaf on the other wall.
Claim 10
Dependent Claim
63 words
A hinge according to claim 1 in which the casing is arranged to be secured in a recess in the surface of the other component, said casing being arranged to be secured in contact with the bottom of the recess and having an outer face arranged to close the recess by lying substantially in the plane of the surface of the other component.
Claim 11
Dependent Claim
42 words
A hinge according to claim 1 in which the casing is formed from first and second members arranged in a superimposed relationship, said members defining the socket therebetween, the first member providing said one wall and the second member the other wall.
Claim 12
Dependent Claim
56 words
A hinge according to claim 10 in which the first member is made from spring steel, and provides a resilient projection in the form of a tongue portion which projects from the first member and is arranged to engage an aperture in said other leaf, and in which the second member is formed from non-resilient material.
Claim 13
Dependent Claim
39 words
A hinge according to claim 10 in which the first and second members are secured together by at least one eyelet, said eyelet providing an aperture through said casing whereby said casing may be secured to the other component.
