Description

April 16, 1968 R. E. FITZGERALD PANEL-MOUNTED LAMP SOCKET Filed Feb. 13, 1967 INVENTOR: ERT E. HTZGERAL R B D, BY MM ATT'Y.
United States Patent 3,378,812 PANEL-MOUNTED LAMP SOCKET Robert E. FitzGerald, Quincy, Mass., assignor to United- Carr Incorporated, Boston, Mass., a corporation of Delaware Filed Feb. 13, 1967, Ser. No. 615,564 Claims. (Cl. 339-127) ABSTRACT OF THE DISCLOSURE This invention relates to a lamp socket mounting having a prong ring fastening device with means for making locking engagement to an apertured support. Locking engagement is made by a V-shaped flexing arm engaged against a V-shaped extension formed on the wall of the aperture.
Background of the invention For many years plug button type fastening devices have been used to provide a means for engaging a lamp socket to an apertured support. The engagement with the support is usually not strong enough to resist accidental impact and may also be upset by prolonged vibration. The risk of having the engagement broken is particularly great in locations where there is a great deal of movement of objects such as the trunk of an automobile, for example.
Summary of the invention -T his is a prong ring fastening device having a series of resilient mounting prongs, one with locking arm, general 1y U-shaped in configuration having a free terminal end with a V-formed portion for engagement with a matching element formed on the Wall of a support. An opposing leg may be utilized which will engage over the opposite side of the aperture from that of the V-shaped portion on rotation of the fastening device or the device to which it is attached. A permanent locking variation can be made by having the arm bent at an angle to the axis of the fastener without the use of the V-shaped portion so that it snaps by a V-portion of the wall of the aperture locking it in position.
Descriplion of the drawing FIG. 1 is a top plan view of the prong ring;
FIG. 2 is a section taken on the line 22 of FIG- URE 1;
FIG. 3 is a top plan view of the prong ring attached to a socket and engaged with an apertured support prior to location;
FIG. 4 is a top plan view similar to that of FIGURE 3 showing the prong ring rotated into locking position;
FIG. 5 is a side elevation of a socket having the prong ring of FIGURE 1 attached thereto.
FIG. 6 is a plan view of a variation of the socket shown in FIGURES 3 and 4.
Description of the preferred embodiments In the drawing, there is shown an annular ring numbered 10, comprising a ring-like base portion 12, having an outer peripheral edge. The outer peripheral edge has a series of resilient-support engaging spring fingers or prongs 14, spaced around the circumference thereof and extending therefrom and a series of extensions 16, protruding from the outer peripheral edge of the plane of the base portion 12.
A number of the spring fingers 14 are formed to provide an inverted U-shaped configuration. One arm 18 of the spring finger 14 is in spaced relation to a support portion 20, which is bent to provide an outwardly exlCe tending knuckle and which is integral with the bight portion of the spring finger 14, as is the arm 18. One of the spring fingers 14 is formed to provide a locking finger which has a support portion 20 connected to a resilient locking portion 24, by a bight portion. The locking portion 24 has a right angle bend formed in it to provide a shoulder 26, and has a flexible supportengaging finger portion which is bent on a lateral plane and which is in angular relationship to the plane of the base portion 12 to form an arced or V-shaped engagement portion 28. The locking portion 28 is extended inwardly toward the axis of a central aperture 30 formed in the base portion 12.
A locking finger 32 is formed extending from the opposite side of the base portion 12, from. that of the locking finger 14 and in opposed relationship therewith. The locking finger 32 comprises a support portion 20 connected by a bight portion to a locking member 34. The locking member 34 is simply one of the spring fingers 14, which is cut short proximate the shallow knuckle. The locking member 34 extends outwardly away from the axis of the central aperture 30, as shown in FIGURE 2.
The annular ring member 10, is shown as embodied in a lamp socket which is formed from a conductive material and comprises a tubular casing 38, having an open end 40, to receive an electric lamp base and another open end which is provided for the passage of leads. Pressed out slots or keyways 42, are formed in the tubular casing 38, which provides locking cooperation with pins or projections on a lamp base. Of course, the improved annular ring member 10 may be used with wedge base bulbs and a different means of engaging the bulb wellknown in the art would be used rather than the slots 42. The open end 40 is provided with an outwardly extending circumferential flange 44, the peripheral edge is bent over and clinched on top of the extensions 16, of the annular ring member 10, whose axis forms a continuation of the axis of the tubular casing 38.
A support 46, which may be the interior of the trunk or a motor vehicle includes an engagement aperture 48, which has a locking tab 50, extending from the edge of the engagement aperture inwardly. The locking tab 50 has an arced camming portion '52, which terminates in a Vshaped slot 54. On the opposite side of the engagement aperture 48, from the locking tab '50, a rectangular notch 56 is formed for a purpose to be explained hereinafter.
To engage the lamp socket with the engagement aperture 48, the spring fingers 14 are pressed against the inner wall of the engagement aperture 48, flexing them inwardly with the locking finger 32 within the rectangular notch 56, and the locking finger 14 in close proximity to the locking tab 50. Subsequent rotation of the lamp socket positions the locking fingers in confronting relationship with the support and causes the V-shaped engagement portion 28 of locking finger 14 to be received in the V- shaped slot 54 of locking tab 50, thus securing the socket in position.
A variation of the locking finger 14 is shown in FIG- URE 6, wherein the engagement portion 28 is formed having a flat surface which is not arced or V-shaped as in the engagement portion 28, but rather is formed to lie on a plane which is parallel in relation to the axis of the annular ring member 10 and inclined to a radius extending normal to the axis. If the variation is engaged with an apertured support similar to the apertured support 46, then as rotation occurred the engagement portion 28 would flex inwardly over the camrning portion 52 and would snap behind the 'camming portion 52, within the V-slot 54, thereby locking it permanently in position.
With reference to the foregoing description it is to be understood that what has been disclosed herein represents only two embodiments of the invention and is to be construed as illustrative rather than restrictive in nature and that the invention is best described by the following claims.
I claim:
