Abstract
Description
- The invention relates generally to fuel filler apparatus connecting a fueling port and a tubular fuel filler pipe in a motor vehicle. More particularly, the invention relates to an improved collar which provides protection for the fuel filler pipe assembly housed in the fuel door recessed compartment of the motor vehicle and further provides support for the rubber boot surrounding the fuel filler pipe.
- In the manufacture of automobiles, the end of the fuel filler pipe leading to the fuel tank is generally closed by a threaded cap or a cap having a bayonet-type connection. The cap may be locked and unlocked by the use of a key. The end of the fuel filler pipe is securely mounted in a recessed fuel filler compartment located on one side of the vehicle body. Generally, the fuel filler cavity further includes a hinged fuel filler door which may contain a locking mechanism.
- The end of the fuel filler pipe is characterized as having a cup-shape provided with an annular flange around its perimeter. The annular flange is seated around an opening in the fuel filler cavity which leads to the interior of the fuel filler pipe by placing resilient material between the annular flange of the fuel filler pipe and the edge of the opening in the fuel filler cavity. Typically, the fuel filler pipe is provided with a second annular flange which defines a seat or throat area between the vehicle body and the second annular flange for accommodating a suitable retaining member by means of which the fuel filler terminal can be mounted in the fuel filler seat. Such assembly is described in U.S. Pat. No. 4,027,910 to Farelli.
- In the assembly of the fuel pipe to the automobile body, a rigid collar is commonly employed as a protecting member for the fuel filler pipe and also as a support for a rubber boot surrounding the fuel assembly to allow escape of fresh air.
- A rigid collar commonly used in the industry comprises three individual lightweight plastic sections which are difficult to assemble and require at least two separate actions involving at least two different directional motions in order to lock the three individual plastic parts together in a sub-assembly while connecting the fuel pipe to the vehicle. In a first action, two halves of the collar are aligned and fitted together and, in a second action, a third annular collar is placed around the two halves to hold them together. Accordingly, there is a need to provide a more simple collar assembly which comprises fewer separate parts, is easier and faster to assemble, and uses a more straight forward approach to lock the part together.
- It is an object of the present invention to provide a fuel filler collar which is designed to overcome the above drawbacks of known fuel filler collars, and more specifically to provide a tubular collar which comprises no more than two separate parts which mate in a simple, single, straight forward push-in action to securely lock the two parts together. According to the present invention, the tubular collar for sealing a fuel filler assembly in a motor vehicle comprises two separate longitudinally semicircular shaped or C-shaped parts which interlock together to form a tubular collar around the fuel filler assembly at the upper end of the fuel filler pipe. Each end of the semicircular parts contains a male and a female locking surface aligned to mate with corresponding female and male locking surfaces on a similar end of an opposing semicircular shaped part. More specifically, when the ends of the two semicircular shaped parts face each other, the male elements on the ends of the semicircular shaped part readily interlock with the female elements on the facing ends of the opposing semicircular shaped part. The positional alignment of the male and female surfaces are preferably reversed in the opposite end of the same semicircular shaped part. In a preferred aspect of the invention, the male and female locking surfaces on one end of each semicircular shaped part are of a different size or other configuration to allow the semicircular shaped parts to be coupled together only in the desired alignment as discussed in further detail below.
- In accordance with the invention, the two longitudinal semicircular shaped parts are easily locked together using a simple, single push-in motion to lock the two semicircular shaped parts securely together and form a collar around the fuel filler assembly.

Associated with thelower notches 28 b, there are also included outwardly extendingarm members arm members - At each of the
ends ends 58 a′ and 58 b′ of the second semicircular shaped structure to provide the collar of the invention. Preferably, the coupling member is a male/female connection as shown in FIGS. 2 through 5 and more fully described below. - FIG. 2 also illustrates a second semicircular
shaped structure 34 similar to the first semicircularshaped structure 24. The second semicircularshaped structure 24 includes a plurality of notches in the upper and lower regions ofouter surface 56′ equivalent to those shown in the first semicircularshaped structure 24; however, only one of the notches, 28 a′ is visible in the second semicircular shaped structure shown in FIG. 2. Theupper notches 28 a′ and thelower notches 28 b′ (FIG. 4) further extend into the uppertapered surface 26 a and the lowertapered surface 26 b, respectively. - At each of the
ends 58 a′ and 58 b′ of the second semicircularshaped structure 34, there is formed a plurality of coupling members designed to cooperate with a similar plurality of corresponding coupling members formed on each of theends shaped structure 24 to provide the collar of the invention. As with the coupling members of the first semicircular shapedstructure 24, the coupling members of the second semicircularshaped structure 34 are preferably a male/female connection. - At both the
upper edge 52 a′ and thelower edge 52 b′ of the second semicircularshaped structure 34, thestructure 34 tapers inwardly, respectively to form an upper taperedarcuate surface 26 a′ and a lower taperedarcuate surface 26 b′. Uppertapered surface 26 a′ terminates in anupper shoulder 50 a′ forming anarcuate rim 54 a′, and lowertapered surface 26 b′ terminates inlower shoulder 50 b′ forming a lowerarcuate rim 54 b. Bothshoulders 50 a′ and 50 b′ extend inwardly perpendicularly to the longitudinal axis of the fuelfiller collar structure 10. - Turning now to FIGS. 4 and 5 which illustrate the
fuel collar 10 of the invention wherein the first semicircular shaped structure and the second semicircular shaped structure are securely locked together, there is illustrated anovel collar 10 and connecting means for protecting a fuel assembly in a fueling port of an automobile. Thecollar 10 consists of two halves locked together. Each half of thecollar 10 comprises a semicircular shaped structure, 24 and 34 which are similar, but not identical, to each other with respect to their structures. - FIG. 5 illustrates one of the plurality of male/female coupling members useful for locking the
ends ends 58 a′ and 58 b′, respectively, of the second semicircular shaped structure in a manner which provides the fuel filler collar of the invention. As shown in FIG. 5, atabular member 30 protrudes from theend 58 b of the first semicircular shaped structure and includes acatch 38 which, upon being inserted into the opening 36′, is resiliently deformed until the catch passes theend 62 oflocking member 60′, whereupon thecatch 38 grasps theend 62′ oflocking member 60′. It is to be understood that the other coupling members cooperate in a similar manner to complete the locking process. - FIG. 6 illustrates a
