United States. Patent 3,177,356 1 RESILIENTLY SUPPORTED LAMP Norbert P. Worden, Detroit, Mich, assignor to C. Hall Lamp Company, Detroit, Mich, a corporation of Michigan Filed June 22, 1961, Ser. No. 118,864 14 Claims. (Cl. 240-415) This invention relates to resiliently supported lamps and more particularly to lamps in which the light unit, such as a sealed beam unit or a bulb assembly, is resiliently supported within a hollow lamp body.
An object of this invention is to improve the resilient mounting of a light unit within a lamp housing.
Another object of this invention is to improve the means for securing a resilient grommet to a lamp body.
Another object of this invention is to improve and re duce the cost of light unit supporting grommets by utilizing extruded grommet material.
Another object of this invention is to improve the establishment of a preselected rotational orientation between a light unit and a lamp body.
Another object of this invention is to secure the two adjacent ends of a discontinuous grommet to a lamp body and to improve the appearance of the exposed disconti unity in the grommet.
The manner of accomplishing the foregoing objects and other objects and features of the invention will be come apparent from the following detailed description of an embodiment of the invention when read with reference to the accompanying drawings in which:
FIGURE 1 is a view in vertical section of a lamp assembly embodying the principles of the present invention;
FIG. 2 is a section taken substantially along the line 2-2 of FIG. 1;
FIG. 3 is an enlarged view of the area 3 on FIG. 2;
FIG. 4 is a fragmentary exploded view of certain of the elements of the structure of FIG. 1;
FIG. 5 is a fragmentary sectional view taken substantially along the line 55 of FIG. 2; and
FIG. 6' is a view of a cly element employed in the structure of FIG. 1.
While the principles of the above invention may be applied to other types of lamp assemblies, they are illustratively embodied in a unit in which a bulb assembly 14), such as a sealed beam unit, is Supported within a lamp body or housing 12 which is relatively non-resiliently mounted upon a vehicle by means including mounting assembly 14.
The lamp body 12 includes a hollow metal shell 15 with a forwardly projecting generally cylindrical flange portion 16, which, in the illustrated embodiment, is actually slightly conical in that it flares outwardly at the forward edge. The diameter of the flange portion 16 is larger than that of the shell portion 15 adjacent thereto and the two parts are interjoined by an angularly disposed portion the outer surface 18 of which forms an exterior circumferential generally rearwardly facing shoulder disposed adjacent and at the rear of the flange portion 16, and the inner surface 21 of which forms an interior generally forwardly facing shoulder portion.
The lamp body 12 supports a bulb assembly 11} including a filament (not shown), a reflector portion 22 and a lens portion 24 all of which are illustratively combined in an integrated assembly in the form of a sealed beam The lens portion 24 (or the lens portion or the reflector portion on a non-integrated unit) is provided 3,177,355 Patented Apr. 6, 1965 with a raised, stepped, circumferential head 26 having a forward circumferential shoulder 28, an intermediate shoulder 29, and a rearward circumferential shoulder 30. In addition, the head is provided with one or more discontinuities such as the boss 32 for rotational keying purposes.
In the illustrated arrangement, the head 26 of the bulb assembly 10 lies within the flange portion 16 of the lamp body 12 and is retained and resiliently supported therewithin by means of a grommet 34. Grommet 34 includes an outer circumferential portion 36 and an inner circumferential portion 38 which are formed integrally with one another, being interjoined at their forward edges. The slot between those portions accepts the flange portion 16, with the inner surface of the outer circumferential portion 36 engaging the outer surface of the flange portion 16, and with the outer surface of the inner circumferential portion 38 engaging the inner surface or" the flange portion 16.
The rear end of the inner circumferential portion 38 of the gasket 34 abuts the interior forwardly facing shoulder portion 20 of the lamp body 12 and the outer circumferential portion 36 is provided at its rear with a lip portion 39 the inner surface of which engages the exterior circumferential rearwardly facing shoulder 18. The former engagement secures the grommet 34 against rearward movement with respect to that lamp body 12, and the latter engagement limits movement of the grommet 34- against forward movement with respect to the lamp body 12. It is contemplated that the rearward movement of the grommet 34 with respect to the lamp body 12 may also or alternatively be restricted by virtue of the engagement of the forward edge of the flange 16 with the base of the groove in the grommet 34.
The inner surface of the inner circumferential portion 38 of grommet 34 is grooved to define a forward, generally annular, radially inwardly directed flange portion 4-0 and a stepped rearward flange portion 42. Flange portion 40 engages the forward circumferential shoulder 28 of the bead 26 and flange portion 42 engages shoulders 29 and 36 of head 26. In this manner, the bulb assembly 10 is secured to the gasket 34 and hence is resiliently held against either forward or rearward of radial movement with respect to the lamp body 12.
As may best be seen in FIGURES 3 and 4, the rearward flange portion 42 of the grommet 34 is provided with a notch, as at 44, to accept the keying boss 32 so as to establish a preselected orientation between the grommet 34- and the bulb assembly 10.
While grommet 34 may be a continuous, molded unit, it is preferred that the grommet be in the form of an extruded strip which is formed into a circle as an incident of the assembly of the grommet to the other elements, with its two ends 48 and 50 (FIG. 5) brought into proximity to one another at one point on the circumference of the bead 26 and flange 16. To locate the grommet 34 in preselected rotational orientation with respect to the lamp body 12, in order to complete the orientation of the bulb assembly 10 with respect to the lamp body 12, a projeca 3 grommet strip be further retained in position by means of a clip 54 (FIG. 6) which is permanently or removably secured to the lamp housing 12 and which engages both the outer and the forward surfaces of the two end portions 48 and 56 of the grommet strip to clamp them in position. In the illustrated arrangement, the shell 15 is provided with ashort transverse slot in which a curved tongue portion 56 of the clip 54 is inserted. Clip 54 is further provided with a resilient forward tongue 56 which is snapped over and into forceful engagementwith the forward surface of the grommet 34, tending to move ends 48 and t) rearwardly. It will be observed that the clip 54 also serves to seal the unit at the channel between the two ends 48 and 5t ofthe grommet and serves to conceal the joint in the grommet.
While it will be apparent objects of the invention, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claims.
