A need exists in the automotive industry for newly simplified and improved illumination and mounting means for use on motor vehicles including structures such as dome lamps, parking lamps, truck lamps, back-up lamps, marker lamps and other applications where lighting might be desired. In some instances, an illumination and lampmounting assembly can include integral switching means and views of FIGURES 1 and 2 illustrate improvements in such an assembly. FIGURES 1 and 2 include a showing of a lampmounting and switch assembly generally indicated by numeral 20 having an elongated base portion 21 of insulating material with a substantially rectangular elongated cavity 22 to be covered by a snap on-otf lens 23 of translucent and flexible plastic material. The lens 23 includes at least a pair of opposite barb-like projections 24 integral therewith and adapted to engage an undercut bezel-like flange portion 25 integral with the base portion 21 and substantially surrounding the cavity 22. Integral adjacent to one end of the base portion 21 there is an extension 26 slotted or apertured to receive a switch button or cam-like actuator 27 engaged by a resilient end or hook-like contact portion 28 displaceable by the button or actuator 27 to be in and out of engagement with a sheet metal mounting member or panel 29 of a motor vehicle. This panel or mounting member 29 can be grounded electrically relative to a battery B which is provided to energize a lampbulb or illumination means as will be de scribed in further detail in the following paragraphs.
The end 28 which is resiliently displaceable for establishing electrical energization relative to the battery B can be an integral part or extension of a terminal means generally indicated by numeral 30 in FIGURE 2 and including a longitudinally extending floor portion which interconnects the end 28 to a lampbulb engaging contact portion 32 extending angularly to one side thereof so as to form a substantially L-shaped configuration. The contact engaging end portion 32 projects through a slot S in the base portion 21 and extends transversely with respect to the elongated cavity 22. A laterally bent tang 33 integral at one end with the contact portion 32 and having a free end abutting against a shoulder 34 can lock the terminal means 30 against inadvertent removal from the base portion 21. Flexibility of the end 28 is enhanced by length of the floor portion 31 of the termi- 3 nal means 30 and fitting of the contact portion 32 to project through the slot S permits the contact portion 32 of the terminal means 30 to abut resiliently against a contact 36 extending axially from a lampbulb generally indicated by numeral 37 and including a cylindrical or substantially annular metal base portion 38 having substantially diametrically opposite lug-like bayonet projections 39 provided laterally therewith. Suitable insulation I can separate contact 36 from the metal sleeve 38 such that opposite ends of a filament (not shown) inside the lampbulb 37 can be electrically attached for energization between the contact 36 and metal sleeve 38. The contact portion 32 of terminal means 30 can provide both electrical engagement for energization as determined by button or actuator movement as well as axial biasing of the lampbulb 37 to have the bulb urged into interlocking engagement with a further terminal means generally indicated by numeral 40 in FIGURE 2.
This terminal means 40 includes a wire crimping portion 41 adapted for direct attachment to a conductor or wire W energized from battery B with the wire W coming directly from an electrical wiring harness and the like to avoid necessity for additional terminal blocks, studs, terminals, blades and other attachments. The crimp portion 41 is integral with a base 42 of a U-shaped portion including a pair of integral contact legs 43 which are adapted to embrace the sleeve-like metal base 38 of the lampbulb 37. Laterally outwardly extending tang means 44 are provided integrally with each of the legs 43 and these tangs 44 are adapted to abut and engage one side of the base portion 21 in locations adjacent to substantially parallel cutouts through which the legs 43 project. The floor-like base 42 integral with both the crimp portion 41 and legs 43 can engage an opposite side of the base portion 21.
The lug-like projections 39 of the bayonet-type lampbulb 37 can engage one of a pair of diametrically oppositely located notch-like recesses 46 under resilient urging of the contact portion 32 of the other terminal means 30 thus establishing electrical interconnection as well as interlocking of the lampbulb and terminal means 40.
FIGURES 3, 4 and of the drawings illustrate in further detail illumination and terminal mounting means similar in structure to that of FIG'URES 1 and 2. In place of terminal means 30 for use in conjunction with a switch portion immediately adjacent to and integral with the lamp-mounting base portion there is provided a modified base portion 48 of insulating material having an elongated cavity 49 therewith and adapted for mounting of a terminal means generally indicated by numeral 50. The terminal means 50 includes a wavy-contact end portion 51 axially and resiliently engageable with a lampbulb means such as 37. Also the terminal means 50 includes a crimp portion 52 angularly disposed with respect to the wavy contact portion 51 and integral therewith. The crimp portion 52 engages one side of the mounting base portion 48 and laterally grooved slots similar to the slot S in base portion 21 can be provided to accommodate the terminal means 50 as well as combination clip and terminal means 40 which are alike for the embodiments of FIGURES 2 and 3.
FIGURE 4 represents an end view taken in the direc tion of arrow 4 in FIGURE 3 to show more clearly how the terminal means 40 provided with legs 43 having notch-like recesses 46 can assure polarized mounting and interlock of the lampbulb means 3'7 thereto. There is a polarized positioning of the lampbulb 37 having the laterally outwardly projecting lugs 39 engageable in the cutout recesses or notches 46 and the contact portion of the secondary terminal means such as represented by numerals 30 and 50 can effect resilient biasing and electrical engagement of the lampbulb means in such polarized positioning.
FIGURE 5 illustrates an end view of structure in the direction of arrow 5 in FIGURE 3. It is to be noted that a tang T assures locking of terminal means 50 relative to the base portion 48 and this tang T can be seen extending integrally from the contact portion 51 in FIGURES 3 and 5. It is to be noted that the interlock and interconnection electrically of the terminal and bayonet-type lampbulb means as resiliently maintained by axial pressure of resilient contact portions can permit horizontal as well as vertical mounting of the lampbulb means depending upon angular positioning of base portions such as 21 and 48.
FIGURES 6 and 7 illustrate side and end views, respectively, of a cartridge-like lamp and terminal mounting means similar to that shown in FIGURES 6, 7 and 8 of US. Patent 3,125,299-Woofter et al. issued March 17, 1964. A lampbulb means generally indicated by numeral 74 includes a central cylindrical glass envelope as well as a pair of opposite metal sleeve-like end portions 75 adapted to fit between arcuate legs 77 of combination clip and terminal means generally indicated by numeral 78. Each of these combination clip and terminal means 78 can have a crimp portion 79 integral therewith as well as laterally outwardly projecting tangs 88 adapted to abut against a mounting panel or base portion 81 having suitable passages or slots therein through which the arcuate legs 77 can be fitted. It is to be noted that the terminal means 78 is difierent than the terminal means 60 which includes the limit projections 63 as well as the stabilizing projection P visible in FIG URES 10 and 11 of US. Patent 3,125,299Woofter et al. issued March 17, 1964.
FIGURE 8 illustrates a base portion generally indicated by numeral 84 providing a cavity 85 extending longitudinally thereof and including provision for mounting two lampbulb means such as generally indicated by numeral 37 as noted for the structure of FIGURE 2. The base portion 84 is made of moldable insulating material and terminal means generally indicated by numeral 48 can be fitted thereto as previously described. Each of the legs or arms 43 of terminal means 40 can be provided with a cutout or notch-like recess 46 in which a bayonet lug or lateral projection 39 of the bulb can be fitted for polarizing engagement therewith. A pair of combination clip and terminal means 40 having such notches can be provided and only a single common ground connection can be provided by use of a terminal means generally indicated by numeral 86 having a generally U-shaped configuration including a midportion 87 which can be provided with an integral crimping or wire attaching portion as well as a pair of resilient legs 88 each provided with wavy end portions 89 which can bias the two lampbulb means 37 in opposite directions axially away from each other though assuring interlocking of the bayonet lugs 39 relative to the notch-like recesses 46 for polarization relative to the terminal means 40. Suitable tangs can be provided on opposite sides and extending integrally from the legs 88 for holding the terminal means 86 in position relative to the base portion 84. It is to be understood that a suitable lens of translucent plastic or glasslike material can be fitted to the base portion 84.
FIGURE 9 provides a side view of a further lamp mounting assembly generally indicated by numeral 90 and including a base portion 91 as well as a lens 92 having integral hook-like projections 93 adapted to snap fit along an underside of a flange 94 of the base portion 91. The base portion 91 can be provided further with a pair of projections 95 and 96 adapted to fit in a mounting panel aperture on a motor vehicle such that a barb or lateral projection 97 integral with the projection or member 96 can establish locked engagement with the aperture having a peripheral edge adapted to be engaged by this barb 97. The lens 92 can be removed from the base portion by rotating the lens in either direction. The lens locking barbs or projections 93 cooperate with ramps 98 adjacent to the flange portion 94. Three or more lens locking barbs or projections 93 can be provided on an annular lens, for example, such that threee slots or openings adjacent to ramps 98 can be provided in the plastic base portion 91. Thus, when the lens is rotated in either direction the angle of the ramps 98 which in effect are edges defining openings adjacent thereto permit the lens locking barbs or projections 93 to conduct the ramps. Continued rotation of the lens causes the lens locking barbs to move inwardly and once the barbs or projections 93 have cleared the opening the lens is released to be removable from the base portion 91. The lens can be easily reassembled to the base portion by aligning the lens locking barbs with the openings or slots provided adjacent to the ramps 98 and the lens can be resiliently snapped into place for locking engagement with the base portion 91.
It is to be understood that base portions such as 21 and 48 can be provided with screw holes for mounting or with integrally molded on springing nibs or projections such as 95-96-97 shown in FIGURE 9. It is to be noted that the illumination and terminal mounting means in accordance with the present invention can be made chiefly of insulating materials including moldable plastic and the like which can be precolored to blend or contrast with interior decorations and upholstery of a motor vehicle. Differing terminal means connected directly to wiring can permit a saving in additional connections and assembly time can be appreciably reduced with a minimum of parts and effort. In view of polarized fit of bayonet projections on a lampbulb means relative to notches with respect to terminal means 40 it is believed that such illumination and mounting means in accordance with the present invention can provide more advantageous and economical assembly and disassembly of components on a motor vehicle.
While the embodiments of the present invention as herein disclosed constitute preferred forms, it is to be understood that other forms might be adopted.
