PMENTEDBEE18 I973 SHEEY 8 UP 8 WATERPROOF TAIL AND CLEARANCE LIGHT SUMMARY OF THE INVENTION This invention relates to an improved waterproof light fixture of the type generally utilized as a tail or clearance light for boat trailers, trucks. etc. The unique construction of this fixture permits its use in extremely moist environments or in instances where complete submersion may occur.

HISTORICAL BACKGROUND AND OBJECTS When launching a boat from a conventional trailer hitched to an automobile, it is customary practice to back the trailer and boat into the water until the trailer is nearly submerged and the boat is free to float on the surface of the water. Such submersion of the trailer presents a serious problem since the tail and clearance lights of the trailer are necessarily submerged also. It has been found that when vehicle lights have been exposed to an undue amount of moisture or submerged, water may leak inside the housing thereby causing rusting and corrosion or possibly short circuiting of the lamp circuit. Such conditions may easily render the trailer unsafe for towing on public highways.

It is therefore, an object of this invention to provide a tail or clearance light assembly which is waterproof and capable of submersion without the leakage of water to-the interior thereof.

Another object of this invention is to provide a tail or clearance light assembly in which easy access to the lamp assembly may be had. i

It is a further object of this invention to provide a tail or clearance light in which a desiccant is enclosed with the fixture thereby precluding fogging of the lens should a small amount of moisture be present therein.

A still further object of this invention is to provide a tail or clearance light assembly which is simple in design and easy to manufacture.

Still another object of this invention is to provide a tail or clearance light assembly wherein the interior of the fixture is sealed by an O-ring compressed between mating portions of the assembly.

Yet another object of the invention is to provide a tail or clearance light assembly having tapered mating surfaces thereby resulting in uniform 360 compression of the O-ring sea].

A further object of this invention is to provide a tail FIG. 4 is a partially exploded side elevational view in section of a further modification of this invention;

FIG. 4A is a top view of the light assembly shown in FIG. 4 where the lens has been removed;

As shown in the drawings:

FIGS. 1 THROUGH 3 Clearance light C includes a base member 2 which is preferably of one-piece construction and made of a material which can be easily molded such as a suitable plastic or the like. It would not be outside the scope of this invention, however, to usemetal or any other material possessing desirable characteristics. Base 2 cornprises generally a sealing portion 4 and a flange 6. Sealing portion 4 is annular as shown in FIG. 3 and forms a shoulder 8 with flange 6. Sealing portion 4 is further provided with a circumferential step 10 the upper sur face of which may be slightly concave so as to more effectively seat resilient O-ring 12 which is disposed thereon. Both the upper portion 14 of the sealing annulus 4 and that portion 16 which is immediately beneath step 10 tapers slightly inward so as to provide a more effective seal as will be described. later.

Cooperating with base 4 is a cap member 18. Cap member 18 is preferably composed of a moldable plastie and includes a lens portion 20 and a reflector poror clearance light assembly having a lens and reflector combination which is inexpensive to manufacture and easy to assemble.

A further object of the invention is to provide an O- ring sealed lamp assembly in which undue distortion of the O-ring is eliminated.

A still further object of this invention is to provide a tail or clearance light assembly which is easy to attach to the vehicle body.

These and other objects of this invention will be apparent from the following description and claims.

In the accompanying drawings which illustrate by way of example various embodiments of this invention:

FIG. 11 is an elevation in section of one embodiment of this invention;

FIG. 2 is a top view of the light assembly shown in FIG. ll;

FIG. 3 is a top view of the light assembly shown in FIG I where the lens and reflector has been removed;

tion 22 integral therewith. The lens portion 20 should be transparent or translucent and of a color complying with the legal requirements for signal lights on vehicles. Reflector portion 22 may be made of the same material as lens 20 but treated in a manner so that it will effectively reflect visible light; Cap member 18 fits telescopically over base member 4 and the inner wall 24 of lens 20 cooperates with the outer surfaces of portions 14 and 16 of sealing portion 4 so as to compress resilient O-ring I2 therebetween. The inner surface 24 of lens 20 and the outer surfaces of portions 14 and 16 are tapered to insure that O-ring 12 is compressed uniformly about its periphery when the cap member is inserted on the base 2. A further advantage of the tapered structure of sealing portion 4 is that O-ring 12 is engaged by the inner wall 24 of lens 20 for only a short distance of the travel of lens 20 over sealing portion 4 before sufficient compression of O-ring I2 is accomplished and the cap member 18 is properly seated on base 2. In this manner any twisting or distortion of O-ring 12 due to the tangential frictional forces created by inner wall 24 sliding over the outer surface of O-ring 12 is maintained at a minimum. Downward movement of cap member 18 onto base 2 is terminated when reflector 22 and rim 28 abut shoulders 8 and 30, respectively. Cap 18 is retained on base 2 by means of an annular ridge or rib 32 on base 2 cooperating with a recess 34 in cap 18. As an alternative to the single ridge 32 which encompasses base 2 and the corresponding mating recess 34 in cap 18, a plurality of spaced protuberances (not shown) on base member 2 may cooperate with a plurality of spaced indentations (not shown) on cap member 18.

Secured to the inner surface 36 of base member 2 is a standard lamp assembly 38 including a light bulb 40 and leads 42 the latter extending through floor 44 into recess 46. Leads 42 may be potted with epoxy resin or the like to insure a water tight seal between the closed receptacle 48 formed by the cooperation of cap 18 and sealing portion 4 and recess 46. Also secured to the floor 44 is a desiccant 50 which may be made of a sheet-like material and retained by an integral stud boss 52, and a cooperating Tinnerman nut 54. Desiccant 50 serves to eliminate any sweating of the interior walls of lens and sealing portion 4 caused by the presence of a small amount of moisture within receptacle 48. The elimination of such sweating substantially decreases the possibility that the lamp assembly may be shorted out or that lens 20 may fail to transmit sufficient light due to the condensed moisture therein. It should be added that while the use of a sheet-like desiccant is preferred in the type of light assembly shown in FIG. 1, other desiccants such as containerized deactivated clay, CaCl Drynite, etc., may be used.

Clearance light C is secured to vehicle body 56 by means of bolts 58 countersunk in flange 6 and cooperating with nuts 60 on the opposite side of vehicle body 56.

FIGS. 4 THROUGH 7 FIG. 4 illustrates a modified version of the clearance light C shown in FIG. 1. Clearance light C comprises generally a base member 62 including flange 64 and sealing portion 66, and a cap member 68. Sealing portion 66 includes an annular upper portion 70, a circumferential recess 72 and a circumferential ridge 74. Disposed within recess 72 is a resilient O-ring 76 which extends slightly beyond the outer surface 78 of sealing portion 66. The interior 80 of sealing portion 66 is sealed and made water tight by the cooperation of the inner surface 82 of cap member 68 cooperating with the outer surface 78 of sealing portion 66 to compress O-ring 72 therebetween. As was the case in the clearance light shown in FIG. 1, both the outer surface 78 of sealing portion 66 and the inner surface 82 of the cap member 68 are tapered so as to provide a uniform seal and maintain the distortion of O-ring 72 at a minimum. Cap member 68 is secured to sealing portion 66 by means of ridge 74 cooperating with recess 84 in snap acting fashion.

Cap member 68 is preferably made of a plastic having resilient characteristics to permit recess 84 to engage ridge 74. Furthermore, the upper portion 86 of cap member 68 should be translucent so as to permitt the transmission of light of the desired wave length. Portion 86 may further be grooved or shaped so as to refract the light which passes therethrough.

Flange 64 may be manufactured separately from sealing portion 66 and preferably made so that it will reflect visible light.

Disposed within the interior of sealing portion 66 are the lamp assembly 88 and desiccant 90 as described in conjunction with FIG. 1. The clearance light shown in FIG. 4 may be secured to a vehicle body (not shown) by any number of means such as a bolt (not shown) passing from the interior 80 of sealing portion 66 through floor 92 and reflector 64. Index stud 94 may cooperate with an appropriate aperture in the vehicle body (not shown) to properly position clearance light C thereon.

FIG. 5 illustrates a structural modification of the clearance light shown in FIG. 4 whereby the cap member 94 is secured to scaling portion 96 by means of O- ring 98. In this modification, the ridge 74 employed in the embodiment shown in FIG. 4 to retain cap member 68 has been eliminated and cap member 94 has been provided with a recess 100 at a position opposite recess 102 when rim 104 abuts shoulder 106. O-ring 102 is compressed slightly between the surfaces of recesses 100 and 102 to seal the interior 108 of sealing portion 96 from the ambient as in the previous examples. 0- ring 98, however, serves a second purpose in that it frictionally retains cap 94 in sealing position by contact with the surface of recess 100.

In FIG. 6, clearance light C comprises a base member 110 including a flange 112 and a sealing portion 114 extending therefrom and a cap member 116 telescopically fitting over sealing portion 114 and secured to base 110 by means of bolts 118 threadedly engaging the internal threads of bolts 120. Bolts 120 are countersunk in flange 112 and serve to fasten the entire assembly to a vehicle body (not shown).

Sealing portion 14 is annular and the outer surfaces 122 thereof are generally frusto-conical in shape. The outer surface 122 of sealing portion 114 has a circumferential recess 124 therein and a resilient O-ring 126 is positioned in recess 124 and cooperates with the inner surface 126 of cap 116 to seal the closed receptacle 128 from the ambient as previously described.

As was the case with the light assembly shown in the previous figures, the upper portion 130 of cap member 116 should be translucent and is preferably shaped to function as a lens. Lamp assembly 132, leads 134 and desiccant assembly 136 are of the type previously described.

FIG. 7 illustrates another way of sealing closed recep' tacle 138 from the ambient. Base 140 comprises a flange 142 and a circular sealing portion 144 extending therefrom and having a circumferential step 146 therein. Step 146 may have a recess 148 therein to retain O-ring 150. The surface of recess 148 cooperates with surface 152 of cap 154 to compress O-ring therebetween and rim portion 156 of cap 154 abuts shoulder 158.

FIGS. 8 THROUGH 11 The light assembly shown in FIG. 8 is of a design most suitable for use as a tail light. Tail light T comprises a base member 160 including a reflecting receptacle 162 and a sealing portion 164 extending therefrom forming shoulder 166, and a cap member 168 made of translucent material.

Receptacle 162 includes floor 170 to which lamp assembly 172 and desiccant 174 are attached. Electrical leads 1'76 pass through floor 170 into recess 178 and are potted by means of epoxy resin or the like to provide sealing of the interior 180 of receptacle 162. Desiecant 174 is preferably made of sheet-like material and secured to floor 170 by means of studs 182 and Tinner' man nuts 184 as previously described. Receptacle 162 is preferably flared so as to best reflect the light generated by bulb 186 through translucent cap member or lens 16.

Scaling the interior 1180 of receptacle 162 at the capreceptacle joint is achieved in a manner similar to that as described in conjunction with FIG. 1. Sealing por tion 164 has a circumferential step188 therein which supports O-ring 190. The outer surface of sealing portion 164 cooperates with the inner wall 192 of cap member 1614 to compress O-ring 190 therebetween. Both the outer surface of sealing portion 164 and the inner wall 192 of cap 168 are tapered inward slightly so as to assure a good seal. Ridge 194 cooperates with recess 196 in snap-acting fashion to retain cap 168 on base 160. Cap rim 197 cooperates with shoulder 166 to limit the downward motion of cap 168 on sealing portion 164 thereby preventing ridge 194 from breaking should cap 168 sustain undue downward force.

Tail light T may be attached to a vehicle body (not shown) by means of metal base 198 secured to base 160 by means of integral Tinnerman nut 200, formed by stamping or the like, cooperating with stud bosses 202 which may be integral with floor 170. Base 198 may then be secured to the vehicle body (not shown) by means of bolts 204.

FIGS. 12 THRGUGH FIGS. 12 through 15 show various methods for both sealing a tail light assembly of the type shown in FIG. 8 and retaining the cap member to the base member.

In FIG. 12, cap or lens 204 has a recess 206 therein which cooperates with Oring 208 seated in recess 210 to both seal the interior 212 of receptacle 214 and secure cap 204 to scaling portion 216. As previously described, the surfaces of recess 206 and 210 compress and frictionally engage the outer surface of O-ring 208. Rim 218 abuts shoulder 220 thereby limiting downward motion of cap 204 onto receptacle 214.

In FIG. 13, the inner surface 222 of cap 224 cooperates with the outer surface 226 of sealing portion 228 to compress O-ring 230 which is seated in recess 232. Ridge 234 cooperates with recess 236 in snap-acting fashion to retain cap 224 about sealing portion 228. Rim 238 abuts shoulder 240 to limit the downward motion of cap 224 which may cause ridge 234 to break.

FlG. 13A illustrates a design which is essentially the converse of that shown in FIG. 13. Inner surface 242 of receptacle 244 cooperates with the outer surface 246 of sealing portion 248 to compress O-ring 250 which is seated in recess 252. Ridge 254 on sealing portion 248 cooperates in snap-acting fashion with recess 256 in receptacle 244 to retain cap 258 on receptacle 244. Rim 260 cooperates with shoulder 262 to prevent cap 258 from being forced within receptacle 244 should it sustain undue downward force. An obvious modification of the assembly shown in FIG. 13A would be to provide surfaces 242 and 246 with matching recesses as in FIG. 13 thereby eliminating the need for ridge 254.

In FIG. 14, lens or cap 264 is secured to receptacle 266 by means of bolts 268 passing through ears 270 and threadedly engaging receptacle ears 272. O-ring 274, which is seated in recess 276, is compressed between the surfaces of recess 276 and shoulder 278.

The light assembly shown in FIG. 15 is similar to that shown in FIG. 14 with the exception that O-ring 280 is retained in recess 282 on the tapered surface 284 of sealing portion 286. Tapered inner surface 288 of receptacle 290 cooperates with the surface of recess 282 to compress O-ring 280.

It should be noted that the sealing portion outer surfaces and receptacle inner surfaces which cooperate to compress the O ring in the embodiments of FIGS. l2, 13, 13A and 15 are tapered so as to achieve a uniform compression of the O-ring and prevent any unnecessary distortion thereof.

In the embodiments shown in FIGS. 1,4, 5, 6, 8, 12, 13, 13A, 15, 16 and 18, it is preferable that the sealing portion outer surfaces taper more gradually than the corresponding mating portion inner surfaces so that the O-ring does not reach maximum compression until the cap member is fully seated. Such a disparity in taper is illustrated in the appropriate drawings.

FIGS. 16 THROUGH 19 In FIG. 16, tail light T comprises a base 292 including a flange 294 and a frusto-conical sealing portion 296 extending therefrom, and a cap member 298 secured to base 294 by means of bolts 300 passing through ears 302 and threadedly secured to internally threaded studs 304. Sealing portion 296 has a circumferential recess 306 which retains a resilient O-ring 308. The inner surface 310 of annular mating portion 312 cooperates with the surface of recess 306 to compress O-ring 308 therebetween. Both inner surface 310 and the outer surface 314 of sealing portion 296 are preferably tapered with sealing portion 296 tapering more gradually than mating portion 312 so that O-ring 308 reaches maximum compression when rim 316 abuts flange 294 and the cap is properly seated.

The embodiment shown in FIG. 17 is similar to that shown in FIG. 16 except for the interface between mating portion 318 of cap 320 and sealing portion 322 of base 324. In this instance, O-ring 326 is seated in a recess 328 in step 330 and compressed between lower surface 332 of mating portion 318 and the concave surface of recess 328.

FIG. 18 illustrates a tail light assembly basically similar to those shown in F165. 16 and 17 but where cap 334 is secured to base 336 by means of bolts 338 passing through flange 340 and threadedly secured within mating portion 342. The entire assembly T is secured to a vehicle (not shown) by means of double threaded bolts 344. As was the case in the embodiments shown in FIG. 16, O-ring 346 is retained in recess 348 and is compressed by mating portion 342.

The embodiment illustrated in FIG. 19 is basically similar to that shown in FIG. 17 with O-ring 350 retained in recess 352 and compressed between sealing portion 354 and mating portion 357. Double threaded bolts 358 provide means for securing the assembly T to a vehicle body (not shown) as described in conjunction with FIG. 18.
