Abstract
Abstract A miniature lamp holder comprises a first inner sleeve in which a diode lamp of parallelepiped shape is engaged, this sleeve having two small opposite faces in which are provided resilient tongues connected to the wall of the sleeve at the rear end thereof, that is to say at the end opposite to that through which the lamp engages. The thickness of the tongues increases towards their free ends. Hence, when a second outer sleeve is engaged on the first one, it acts on the tongues to press them against the lamp and thus maintain the lamp in place.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
A miniature lamp holder comprising a first inner sleeve having an opening, the cross-sectional shape of which corresponds to that of a lamp to be held, in which sleeve the lamp is engaged, and a second outer sleeve surrounding said first sleeve, in which said first sleeve has a wall and is provided with at least one resiliently deformable small tongue provided in said wall, said tongue being connected to said wall in the neighbourhood of an end of said first sleeve opposite to that end through which the lamp is engaged, the thickness of said tongue increasing from an end thereof connected to said wall towards a free end of the tongue, the arrangement being such that, when said second sleeve is engaged on said first sleeve, it acts on said tongue to press it inwardly against the lamp so as to maintain the lamp in place in the first sleeve.
Claim 2
Dependent Claim
152 words
A miniature lamp holder comprising a first inner sleeve having an opening, the cross-sectional shape of which corresponds to that of a lamp to be held, in which sleeve the lamp is engaged, and a second outer sleeve surrounding said first sleeve, in which said first sleeve has a wall and is provided with at least one resiliently deformable small tongue provided in said wall, said tongue being connected to said wall in the neighbourhood of an end of said first sleeve opposite to that end through which the lamp is engaged, the thickness of said tongue increasing from an end thereof connected to said wall towards a free end of the tongue, the arrangement being such that, when said second sleeve is engaged on said first sleeve, it acts on said tongue to press it inwardly against the lamp so as to maintain the lamp in place in the first sleeve.
Claim 3
Dependent Claim
67 words
A lamp holder as claimed in claim 1, in which both said sleeves are striated transversely with respect to a longitudinal sleeve axis, the first sleeve being striated outwardly and the second sleeve being striated inwardly, so that the striation grooves of one of said sleeves engage the striation grooves of the other one of said sleeves whereby to maintain the assembled condition of said two sleeves.
Claim 4
Dependent Claim
59 words
A lamp holder as claimed in claim 1, for use with a lamp of parallelepiped shape, in which said opening of the first sleeve is of rectangular cross-sectional shape and said first sleeve has two opposed faces, and said resiliently deformable small tongue is one of two such tongues respectively provided in said opposed faces of said first sleeve.
Claim 5
Dependent Claim
42 words
A lamp holder as claimed in claim 1, for a lamp having the shape of a right prism with a triangular base, in which the first sleeve, of corresponding sectional shape, has said small tongue provided in one of its three faces.
Claim 6
Dependent Claim
44 words
A lamp holder as claimed in claim 1, for use with a lamp of circular section, in which the small tongue provided in the wall of the first sleeve, which is cylindrical, is of a section having the shape of a segment of circle.
