ADAPTER FOR MARKER LIGHT BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to marker light mounting arrangement for vehicles and particularly relates to an adapter arrangement for mounting any type of marker light to the vehicle provided with recessed electrical conductor means. The invention has particular use to the mounting of marker lights to the upper quarter panel of a highway trailer.

2. Description of the Prior Art The prior art, as, for instance, U. S. Pat. No. 3,087,051, provides for the mounting of such marker lights over the recessed electrical cable or hot wire mounted in a groove in the upper quarter panel of the trailer vehicle. However, there are many different types of marker lights which can be purchased and mounted on the vehicle where the quarter panel is not provided with a recessed cable which carries the electrical conductor for lighting the light. It is, therefore, desirable to provide for adapting structure in which any type of marker light may be used on a quarter panel with a recessed cable and it is to this end that the invention is committed.

SUMMARY It is, therefore, a general object of this invention to provide for an adapter arrangement which permits the use of any type of marker light on a vehicle using a recessed type of cable or hot wire for lighting a series of marker lights strung along the upper quarter panel of the vehicle or trailer. The invention provides for a receptacle or housing for carrying the lead wire from the mounted marker light and which further holds the guide or leader bushing carrying the piercing screw firmly against and over-the insulation cable or hot wire recessed in the quarter panel. The receptacle mounting face is designed to be held'for flushness and watertightness against the vehicle side and in order to maximize adherence force the contact area of the mounting face is reduced to a minumum by being ribbed. The bottom part of the adherence or mounting surface is undercut to a drain area to provide for drainage of condensation or any water seepage from the adapter and an adapter retainer provided with a center ring to hold the leader bushing and with an outer ring to assure water-tightness of the assembly. The top of the adapter is provided with a self-sealing slit through which the bit of a screwdriver can be pushed in order to operate the piercing screw.

These and other advantages and objects of the invention will become apparent from reference to the following description, attached drawings and appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 6 is a sectional view taken along line 6-6 of FIG. 5;

FIG. 7 is an end elevational view of the adapter receptacle;

FIG. 8 is a cross sectional view of the adapter mounted on the quarter panel of a trailer vehicle; and

FIG. 9 is a longitudinal sectional view of the adapter mounted on the side or quarter panel of the trailer.

DESCRIPTION OF THE PREFERRED EMBODIMENT The invention will be described [herein with particular reference to the installation of the marker light and its adapter in the upper quarter panel of a semi-trailertype roadway vehicle. The upper quarter panel is that structural section which extends along the upper edge corner of the cargo body.

As shown in FIGS. 1 and 2, the cargo body 2 for a semi-trailer 4, or the like, has an upper quarter panel 6 on which marker lights 8 and marker light adapters 10 are mounted. In the embodiment shown, the marker lights each have a light bulb 12 which is on socket and vehicle mounting device 14 which is secured to the quarter panel by ground screws 16.

With reference now to FIGS. 3-9, extending from each marker light is a marker light electrical lead or wire 18 which extends into the tubular opening 20 of the adapter receptacle 22 of its associated adapter 10. The wire 18 has its marker light connector 24 coupling with the adapter connector 26 which at its innerend has an apertured flange 28 through which extends the piercing screw 30. The screw 30 is threadedly secured in the nylon leader bushing or guide 32 that is surrounded by the very soft or rubber-like plastic adapter receptacle 22. The opening 20 permits plugging of the marker light connector 24 into the connector 26 with the tubular opening 20 tightly encasing-the connector 18 to provide for water-tight connection. The top 34 is provided with a self-sealing slit 36 through which the bitof a screwdriver can be pushed in order to operate the piercing screw 30. The receptacle is provided with a cavity 38 in which resides the bushing 32. The cavity 38 has a counter-bore portion 40 (see FIGS. 8 and 9) to provide an annular shoulder portion 42 to entrap the annular flange portion 44 of the bushing 32 which has a reduced stern portion 46 which receives the head 48 of the piercing screw 30 and the flange 28 of the connector 26. The bushing is provided with a lower tapered bottom portion 47 (see FIG. 8) underneath the central flange portion 44 that projects laterally outwardly of the bottom 47 and the top reduced stem portion 46. The cavity 38 is also provided with an upper vertical bore 39 (see FIG. 9) which joins with the counter-bore 40 and has in its roof 41 the slit 36. The cavity 38 is further defined by the tubular passageway or opening 20. The exterior upper part 45 of the receptacle 22 is generally cylindrical in shape except for the extension 21 that projects out from it and in which is formed passage 23 to receive the wire of the marker light. The passage 23 communicates with the flexible.

opening 20 of the end portion 19 of the extension 21.

The counter-bore 40 which defines the annular shoulder 42 of the receptacle 22 defines an outwardly extending central ring portion 50 of the receptacle 22 and extending radially outwardly from and below this ring section 50 is an outer flat ring portion 52 of the receptacle 22. The raised inner ring section 50 and the lower outer ring portion 52 form a stepped rim.

The outer ring portion 52 is provided with a cutout or annular drainway 54 (see FIG. which communicates with a lower discharge passage or undercut 56 for draining any moisture or condensation outwardly of the receptacle. The outer flange or ring 52 of the receptacle that is provided with the drain passage 54 defines a series of four downwardly extending receptacle leg portions 58, 60, 62 and 64 each of which is provided with, in its outer surface, a grooved or cutout portion 66 which allows for the bottom of the receptacle to partially encase the insulated conductor or cable or hot wire 68 that is stored in the longitudinally extending quarter panel groove 70. The bushing 32 is also provided in its bottom with a groove 33 (see FIG. 9) to cooperate with the grooves 66 in receiving the electrical conductor 68. The arcuate cutouts 66 in the legs 58, 60, 62 and 64 of the receptacle 22 and arcuate cutout of the bushing 32 are pressed about the cable by the clamp retainer 72 which is in the shape of an annular ringed stepped rim structure having a central opening or bore 74 and an upper inner ring portion 76 and a lower or recessed outer ring portion 78 having an outer upturned annular flange 80. The inner ring 76 rests on the inner shoulder or central ring portion 50 and the outer ring 78 seats on the outer ring portion 52 of the receptacle. The screws 82 and 84 extending through the openings 87 (see FIG. 8) in the retainer 72 and the openings 86 and 88 (see FIG. 5) in the receptacle provide for clamping of the more rigid or stiff retainer against the more flexible receptacle 22. The center ring 76 of the retainer 72 provides the holding force for the leader bushing 32 and the outer ring 78 of the retainer 72 assures water-tightness of the assembly.

With reference to FIGS. 5-7, it will be seen that the rings or mounting faces 90 and 92 which define drain area 54 (see FIG. 5) depend from the underside 91 of the receptacle 22 on either side of the drain passage 54. The outer mounting face 90 surrounds the receptacle outer periphery and the inner mounting face area 92 surrounds the counter-bore 40. These mountings faces 90 and 92 are ribbed, as are the annular flanges 94 and 96 (that depend from the receptacle underside 91) that define the openings 88 and 86 due to the formation of ribs or projections 98 because of cutouts 100 formed therebetween. This combination of ribs 98 and cutouts 100 provide for a mounting face area that is designed for water-tightness and at the same time, maximize the adherence force, because the contact area is reduced to a minimum while the undercut 56 at the bottom 102 (see FIG. 5) allows for drainage.

This adapter is designed to enable one to install any type of marker clearance light on the quarter panel 6 which is provided with a groove 104 (see FIG. 8) in which sits the bottom 47 of the bushing 32. The quarter panel 6 is further provided with an annular or circular groove 106 which carries the cable 68 and communicates by passage 108 with the panel groove 104. At the time of light installation without using an adapter, the cable or wire on the quarter panel is pierced by screwing in the piercing screw of the marker light, which screw punctures the insulation 110 of the electrical conductor 68 and penetrates into the strands of the electrical current conducting wire 112. In order to install a different marker light, as exemplified in FIG. 2 by marker light 8, the adapter 10 with its own piercing screw 30 is used as a means of connection between the marker light 8 and the recessed wire 112. The body of the van 4 acts as an electrical ground and completes the circuit to the battery 114 shown schematically (see FIG. 1). The adapter connector 26 provides a socket for a common bullet-type plug at the end of the marker light electrical connector 18. This connector 26 then becomes rigidly fastened to the adapter receptacle by tightening the piercing screw 30 in the bushing 32. At the same time, the screw 30 becomes the natural conductor between the pierced wire 112 and the bullettype plug of the electrical connector 18. The adapter 10 may be placed at the front or at the rear of a marker light 8. For mounting on the trailer, the adapter is delivered as a unit which is assembled as shown in FIG. 9. The piercing screw 30 should be unscrewed to the point that the tip of it will not touch the quarter panel wire 112. Orientate the adapter assembly 10 so that the undercut 56 is downward or at the bottom which provides for drainage of moisture or leakage. The adapter is mounted with the two screws 82 and 84, one at the bottom and one at the top. A screwdriver is inserted through the slit 36 and the piercing screw 30 is tightened such that the wire 112 is pierced by the tip of the screw and the connector of the adapter is rigidly fastened in place. In completing the wiring, the marker light connector is plugged into the receptacle 22.
