Abstract
Abstract A lamp removal arrangement for a panel mounted illuminated device having a tubular housing in which a wedge base lamp is supported and further having a light transmitting closure which includes resilient fingers that pass over the tubular position of the lamp during assembly of the closure to the housing and that rigidly engage the portion of the lamp located between the tubular portion and the base portion upon removal of the closure from the housing so as to thereby cause the lamp to be removed therewith.

Claim 1
Independent Claim
226 words
A lamp removal arrangement for a panel mounted illuminated device comprising: a. a tubular housing having a cavity terminating as an opening at one extremity; b. a detentably secured, selectively removable closure including a light transmitting means arranged to cover said opening; and c. socket means for a wedge base lamp supported within the cavity of said housing and located so that insertion and removal of said lamp take place along an axis co-extensive with the longitudinal axis of said housing; d. said closure including oppositely disposed side members depending from said light transmitting means which are arranged to straddle said lamp when both are in place in said housing; e. at least one of said side members having a resilient element arranged to be displaced from its normal position and against its inherent bias by and to completely pass over the tubular portion of said lamp upon forward movement and assembly of said closure into said housing; f. said resilient element thereupon moving toward its normal position and rigidly engaging the connecting portion located Between the tubular portion and the base portion of said lamp upon outward movement and selective removal of said closure from said housing, such removal and engagement and the resulting engagement between said lamp and the other of said side members causing said lamp to be removed from said socket means.

Claim 3
Dependent Claim
44 words
The arrangement of claim 1 wherein each of said side members includes a resilient element which completely passes over the tubular portion of said lamp during assembly and rigidly engages the connecting portion of said lamp upon removal of said closure from said housing.
Claim 4
Dependent Claim
34 words
The arrangement of claim 2 wherein said resilient elements are in the form of fingers extending toward each other and the longitudinal axis of said closure and further extending toward said light transmitting means.
Claim 5
Dependent Claim
18 words
The arrangement of claim 3 wherein said resilient fingers are integrally formed and struck from said side member.
Claim 6
Dependent Claim
49 words
The arrangement of claim 4 wherein said closure member is substantially tubular in form with an opening opposite said viewing surface and wherein said lamp can be loosely retained therein by the walls thereof and said resilient fingers upon removal of said closure and said lamp from said housing.
Claim 7
Dependent Claim
40 words
The arrangement of claim 5 wherein an opening is provided in a side wall of said closure of such a size as to allow passage of said lamp therethrough upon removal of said closure and said lamp from said housing.
