Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
205 words
A lamp socket having a body comprising: at least one fixing member mounted on said body having groove means for receiving the base pins of a lamp with said base pins each having a longitudinal axis; at least one pushing member having at least one lever arm and an end portion inserted in said groove means, said pushing member being pivotally mounted, adjacent to said fixing member, about an axis which extends substantially prependicular to the longitudinal axis of the base pins, spring means mounted on said fixing member, said spring means normally biasing said pushing member against the base pins of a lamp inserted in said groove means to thereby bias the base pins against said fixing member with said spring means applying a force to said pushing member in a generally longitudinal direction relative to the axes of the base pins, said pushing member being releasable from biasing the base pins against said fixing member when said pushing member is displaced a predetermined distance against the applied force of said spring means to thereby permit a substantially resistance free insertion of the base pins within the said groove means in a substantially resistance free removal of the base pins from said groove means.
Claim 2
Dependent Claim
205 words
A lamp socket having a body comprising: at least one fixing member mounted on said body having groove means for receiving the base pins of a lamp with said base pins each having a longitudinal axis; at least one pushing member having at least one lever arm and an end portion inserted in said groove means, said pushing member being pivotally mounted, adjacent to said fixing member, about an axis which extends substantially prependicular to the longitudinal axis of the base pins, spring means mounted on said fixing member, said spring means normally biasing said pushing member against the base pins of a lamp inserted in said groove means to thereby bias the base pins against said fixing member with said spring means applying a force to said pushing member in a generally longitudinal direction relative to the axes of the base pins, said pushing member being releasable from biasing the base pins against said fixing member when said pushing member is displaced a predetermined distance against the applied force of said spring means to thereby permit a substantially resistance free insertion of the base pins within the said groove means in a substantially resistance free removal of the base pins from said groove means.
Claim 3
Dependent Claim
196 words
A lamp socket having a body comprising: at least one fixing member mounted on said body having aperture means for receiving base pins of a lamp, said fixing member also having at least one guide hole; at least one pushing member slidably disposed within said guide hole of said fixing member, said pushing member having spring means and wedge hole means for holding the base pins, said wedge hole means having at least one side portion thereof formed as a surface inclined with respect to the moving direction of said pushing member, said spring means normally biasing said pushing member against base pins of a lamp inserted in said aperture means to thereby bias the base pins against said fixing member, said spring means applying a force to said pushing member in a predetermined direction, said pushing member being releasable from biasing the base pins against said fixing member when said pushing member is displaced a predetermined distance against the applied force of said spring means to thereby permit a substantially resistance free insertion of the base pins within said aperture means and a substantially resistance free removal of the base pins from said aperture means.
