Device for installing within a panel opening for supporting an electrical component or the like

Claim 2

In a device adapted to be installed within an opening in a panel for supporting an electrical component or the like, said device including a hollow housing adapted to extend through the opening, said housing having an annular forward end portion projecting forwardly of the panel and an annular rearward end portion projecting rearwardly from the panel, means defining a peripherally extending external groove within said housing between said forward and rearward end portions for receiving the panel, means defining a slot within said housing and extending rearwardly through said forward end portion and interrupting said groove, said slot providing for partially collapsing said forward end portion of said housing or inserting said housing into the opening until the panel seats within said groove, the improvement comprising a retaining member mounted on said forward end portion of said housing and including an annular portion surrounding said forward end portion and covering said slot, a rib projecting inwardly from said annular portion of said retaining member into said slot, and said rib is effective to prevent collapsing of said forward end portion of said housing after said groove receives the panel and to effect a positive locking of said housing to the panel.

Claim 3

A device as defined in claim 1 wherein said rib projects radially inwardly from said annular portion of said housing.

Claim 4

A device as defined in claim 2 wherein said retaining member includes a lip portion projecting inwardly from said annular portion, said retaining member includes a plurality of said circumferentially spaced said ribs projecting inwardly in axially spaced relation to said lip portion, a cover element including a peripheral flange portion seated between said ribs and said lip portion, and said housing includes a corresponding plurality of said slots for receiving said ribs.

Claim 5

A device as defined in claim 1 and including a lens element secured to said annular portion of said retaining member.

Claim 6

A device as defined in claim 1 wherein said housing comprises a generally frusto-conical hollow portion extending from said groove rearwardly, and a generally cylindrical tubular end portion extending rearwardly from said frusto-conical portion of said housing.

Claim 7

A device as defined in claim 5 wherein said tubular end portion of said housing includes a plurality of generally axially extending internal ribs, and an electrically actuated component is disposed within said tubular end portion firmly engaging said internal ribs.

Claim 8

A device as defined in claim 1 wherein a plurality of peripherally spaced and axially extending said slots interrupt said groove, and a plurality of peripherally spaced said ribs project inwardly from said annular portion of said retaining member into the corresponding said slots.

Claim 9

A device as defined in claim 1 wherein said slot and said rib include mating interfitting teeth for locking said retaining member onto said housing.

Claim 10

In a device adapted to be installed within an opening in a panel for supporting an electrical component or the like, said device including a hollow housing of molded plastics material and adapted to extend through the opening, said housing having a generally cylindrical forward end portion projecting forwardly of the panel and an annular rearward end portion projecting rearwardly from the panel, means defining a peripherally extending external groove within said housing between said forward and rearward end portions for receiving the panel, means defining a plurality of peripherally spaced slots within said housing and extending rearwardly through said forward end portion and interrupting said groove, said slots providing for partially collapsing said forward end portion of said housing for inserting said housing into the opening until the panel seats within said groove, the improvement comprising a retaining member mounted on said forward end portion of said housing and including an annular portion surrounding said forward end portion and covering said slots, said retaining member including a corresponding plurality of peripherally spaced ribs projecting inwardly from said annular portion into said slots, and said ribs being effective to press into said slots to prevent collapsing of said forward end portion of said housing after said groove receives the panel and to effect a positive locking of said housing to the panel.

Claim 11

In a device adapted to be installed within an opening in a panel for supporting an electrical component or the like, said device including a hollow housing of molded plastics material and adapted to extend through the opening, said housing having a generally cylindrical forward end portion projecting forwardly of the panel and an annular rearward end portion projecting rearwardly from the panel, means defining a peripherally extending external groove within said housing between said forward and rearward end portions for receiving the panel, means defining a plurality of peripherally spaced slots within said housing and extending rearwardly through said forward end portion and interrupting said groove, said slots providing for partially collapsing said forward end portion of said housing for inserting said housing into the opening until the panel seats within said groove, the improvement comprising a retaining member mounted on said forward end portion of said housing and including an annular portion surrounding said forward end portion and covering said slots, said retaining member including a corresponding plurality of peripherally spaced ribs projecting inwardly from said annular portion into said slots, and said ribs being effective to press into said slots to prevent collapsing of said forward end portion of said housing after said groove receives the panel and to effect a positive locking of said housing to the panel.

Claim 12

A device as defined in claim 9 wherein said retaining member includes an inwardly projecting annular lip spaced in front of said ribs, and a cover member having an outwardly projecting peripheral flange disposed between said lip and said ribs.

Claim 13

A device as defined in claim 10 wherein said cover member comprises a lens of light transmitting material.

Claim 14

A device as defined in claim 9 wherein said rearward end portion of said housing includes a substantially cylindrical tubular portion having a diameter smaller than the diameter of said forward end portion, and an electrical lamp socket is press-fitted within said tubular portion.

Claim 15

A device as defined in claim 9 wherein said rearward end portion of said housing encloses an electrical lamp socket, said housing having means firmly engaging said lamp socket, and a light transmitting lens secured to said retaining member.
