Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims priority under 35 U.S.C. 119, based on Japanese patent application No. 2002-266074, filed Sep. 11, 2002.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a fuel inlet structure for a personal watercraft. More particularly, the present invention relates to a fuel inlet structure including a fuel fill tube, with a fuel filler cap restrained by of a chain interconnecting the fuel filler cap and the fuel fill tube, to prevent loss of the fuel filler cap or damage to the personal watercraft during fuel filling service.
[0004] 2. Description of the Background Art
[0005] One fuel inlet structure for a personal watercraft is known wherein a chain is attached to a fuel fill tube, and connects the fill tube to a cap provided for closing up an open end of the fuel fill tube. For example, Japanese Laid-Open Patent No. 2000-53091 has this type of connection.
[0006]
FIG. 9 of the present application is copied from FIG. 1 of the official gazette of Japanese Patent Laid-Open No. 2000-53091, for purposes of explanation of this published reference.
[0007] According to the conventional prior art fuel filler structure 100 for a personal watercraft illustrated in FIG. 9, an opening 102 is perforated in a deck 101 to receive fuel and direct it to the appropriate storage receptacle on the watercraft. A fuel fill tube 105 having a fuel filler neck 104 fits into the opening 102, with a gasket 103 interposed therebetween. A fill cap 107 is also provided for closing up the top of the fuel filler neck 104, and another gasket 108 forms a seal between the fill cap 107 and the filler neck 104.
[0008] A chain 106 extends from the fuel fill tube 105, as shown, and the chain can be attached to the fill cap 107. The known fuel filler structure 100 for a personal watercraft shown in FIG. 9 prevents of the fill cap 107 from dropping into water upon fueling, since the fill cap 107 is physically connected to the fill tube 105 by the chain 106.
[0009] With the known fuel filler structure for a personal watercraft described above, when the fill cap is suspended on the fuel fill tube by the chain, the chain sometimes impacts on the fuel fill tube or on a member around the deck and damages the fuel filler or the deck.
[0010] Further, when the chain impacts on the fuel filler or a member around the deck, the chain itself may be damaged, which shortens the life of the chain.
[0011] Although the known filler structures are useful for their intended purposes, a need still exists in the art a fuel filler structure for a personal watercraft in which the fuel filler structure can prevent damage to a fuel fill tube or a deck, and can minimize the risk that a chain will cause damage to a fill tube or to the deck of the watercraft.
SUMMARY OF THE INVENTION
[0012] In order to achieve the object described above, a fuel filler structure according to a first illustrative embodiment of the present invention is provided for a personal watercraft having a craft body including a deck, a fuel fill tube installed on the deck, and a fuel tank disposed in the craft body with a fuel hose extending from the fuel tank and having an end thereof connected to the fuel fill tube on the deck.
[0013] In the first embodiment hereof, a chain is provided for interconnecting the fuel fill tube and a filler cap or the watercraft. One end of the chain is fastened to the inside of the fuel fill tube member, and the other end of the chain is fastened to a fill cap. The fill cap is provided to sealably close up a fuel fill tube of the fuel fill tube member. Also in the first embodiment hereof, the chain includes a protective tube at a location thereof which contacts with the fuel fill tube when the fill cap is removed.
[0014] By providing a protective tube around the portion of the chain attached to the fuel filler tube, the risk of the chain causing damage to either fuel filler or a deck can be reduced, and damage to the chain itself can be minimized or prevented.
[0015] Therefore, the chain includes the protective tube at the location thereof where the chain contacts the fuel filler when the fill cap is removed, so that damage to the fuel filler or the deck is substantially prevented and the chain itself also protected. As a result, fuel can be supplied without paying unnecessarily high attention to the fuel filler or to the deck, and improvement in workability of the fueling operation can be anticipated.
[0016] According a second illustrative embodiment of the present invention, the chain includes a stopper thereon, for stopping movement of the protective tube up the chain.
[0017] Since the stopper for stopping movement of the protective tube is provided on the chain, the protective tube is retained at a necessary location on the chain. As a result, the protective tube can be partially attached to a location on the chain for which protection is required, and the effectiveness of protective tube can be maximized.
[0018] Optionally, the stopper may be provided in the form of a bead integrally provided on the chain. Where the stopper is a bead integrally provided on the chain, correct placement of the protective tube on the chain can be attained, for example, by simply sliding the protective tube onto the chain and attaching the fill cap to the end of the chain. As a result, improvement in installing the protective tube can be realized.
[0019] Alternatively, the stopper may be provided in the form of a slit washer which can be attached to the chain subsequent to initial assembly. Where the stopper is formed as a slit washer which can be attached to the chain subsequent to initial assembly, it is possible, for example, to slide a plurality of protective tubes onto the chain, and attach the protective tubes at an arbitrary position of the chain with a slit washer later. As a result, expansion of the utility of the protective tube can be realized.

[0056] The fuel filler structure 60 for a personal watercraft includes the tubular routing structure 69 provided in the fuel fill neck 62. The routing structure 60 has the fuel filler 69a (refer to FIG. 4) formed at one end thereof, and has the hose connecting portion 69b formed at the other end thereof. Further, the projections 69c for positioning the end of the fueling nozzle N1 (refer to FIG. 4) for supplying fuel therethrough are formed intermediately in the passage within the routing structure 69. Therefore, the fueling nozzle N1 can be prevented from unnecessarily entering the fuel supply hose 63 or the fuel tank 13 (refer to FIG. 3).
[0057] As a result, the fueling nozzle N1 can be prevented from hitting the fuel supply hose 63 or the fuel tank 13. Further, it is shown that the projections 69c may include three projections projecting from the routing structure 69.
[0058] Action of the fuel filler structure 60 for a personal watercraft described above is explained below.
[0059] FIGS. 6(a)-(c) show a series of sequential sectional views of the fuel filler structure of FIGS. 2-3, illustrating use thereof during a filing operation.
[0060] In FIG. 6(a), the fill cap 65 is removed from the fuel filler 69a as indicated by an arrow mark (1)↑.
[0061] In FIG. 6(b), since the fill cap 65 can be suspended as indicated by an arrow mark (2)↑ by the chain 68, there is no possibility that the fill cap 65 may drop into water. Thereafter, the fueling nozzle N1 is inserted into the fuel filler 69a as indicated by an arrow mark (3)↑.
[0062] In FIG. 6(c), the end of the fueling nozzle N1 is brought into abutment with the projections 69c of the routing structure 69 as indicated by an arrow mark (4)↑. In other words, the fueling nozzle N1 can be prevented from unnecessarily entering the fuel supply hose 63 or the fuel tank 13 (refer to FIG. 3).
[0063] Further, since one end 68a of the chain 68 is connected to the fuel fill neck 62 at a position lower than the projections 69c, the fueling nozzle N1 does not hit the end 68a of the chain 68. As a result, interference with the fastening portion 69d of the fuel fill neck 62, to which the end 68a of the chain 68 is connected, can be prevented.
[0064]
FIG. 7 is a front elevation sectional view of a fuel filler structure 80 for a personal watercraft according to a second embodiment of the present invention. Parts of the structure 80 which are substantially identical to those used in the first embodiment of a fuel filler structure 60 for a personal watercraft (refer to FIG. 3) are denoted by like reference characters, and detailed description thereof is omitted. It will be understood that components of the structure 80 which are not specifically described as being different from the structure 60 are substantially identical to those described in connection with the first embodiment.
[0065] The fuel filler structure 80 for a personal watercraft, according to the second embodiment, is configured such that in a fuel filler structure for a small size craft of the type wherein a fuel tank 13 is disposed in a craft body 11 (FIG. 1) and a fuel supply hose 81 extends from the fuel tank 13 with an end thereof connected to a fuel filler member 82 on a deck 20 while one end of a chain 83 is fastened to the inside of the fuel filler member 82 and the other end of the chain 83 is connected to a fill cap 84, the chain 83 includes a protective tube 86 as a sleeve surrounding the chain 83, at a location where the chain 83 contacts the fuel filler 85 when the fill cap 84 is removed.
[0066] In FIG. 7, reference numeral 87 denotes a bead attached to an intermediate portion of the chain 83. The bead 87 serves as a stopper for stopping movement of the protective tube 86. A washer 88 is attached to an end of the chain 83, for connecting the chain to a fastening portion 89 formed on the fill tube.
[0067] Also in the embodiment of FIG. 7, a projection 91 is formed on the inside of the fuel filler member 82 for limiting the entry distance of the fueling nozzle Ni, and a hose band 94 is provided for clamping the supply hose 81 to the lower end of the fuel filler member 82. The projection 91 provides a stop member, disposed within the tubular routing structure, for limiting the extent to which a fuel nozzle can be inserted therein.
[0068] It is preferable if, for example, damage to a fuel filler or a deck can be prevented and a chain itself can be prevented from causing damage thereto.
[0069] Therefore, the chain 83 includes the protective tube 86 at the location thereof at which the chain 83 is to contact the fuel filler 85 when the fill cap 84 is removed, so that damage to the fuel filler 85 or the deck 20 is prevented, and the chain 83 itself is prevented from causing damage thereto. As a result, fuel can be supplied without paying unnecessarily high attention to the fuel filler 85 or the deck 20, and improvement in workability of the fueling operation can be anticipated.
[0070] Further, the fuel filler structure 80 for a personal watercraft is characterized in that the chain 83 includes a stopper for stopping movement of the protective tube 86.
[0071] Since the stopper (bead) 87 for stopping movement of the protective tube 86 is provided on the chain 83, the protective tube 86 can be retained at a necessary location of the chain 83. As a result, the protective tube 86 can be partially attached to a location of the chain 83 for which protection is required, and achievement of effective utilization of the protective tube 86 can be anticipated.
[0072] Furthermore, where the stopper 87 is a bead integrally provided on the chain, movement of the protective tube 86 on the chain 83 can be stopped, for example, only by threading the protective tube 86 onto the chain 83 and attaching the fill cap 84 to the chain 83. As a result, improvement in assembling property of the protective tube 86 can be anticipated.
[0073] FIGS. 8(a) and (b) are different form schematic views of the chain of a fuel filler structure for a personal watercraft of the second embodiment according to the present invention. (a) of FIG. 8 shows the front of a chain 93 of the different form, and (b) of FIG. 8 shows the front of a stopper 97.
[0074] Referring to of FIGS. 8(a) and (b), the chain 93 includes a slit washer as the stopper 97 and allows a protective tube 96 to be fastened to the chain 93 later. In (a) and (b) of FIG. 8, reference numeral 98 denotes a washer attached to an end of the chain 93, and 99 a slit portion of the stopper 97.
[0075] Where the stopper 97 is formed as a slit washer that can be attached to the chain 93 later, it is possible, for example, to thread a plurality of protective tubes onto the chain 93 and attach the protective tubes 96 at an arbitrary position of the chain 93 with a slit washer later. As a result, expansion of the utility of the protective tube 96 can be anticipated.
[0076] It is to be noted that, in the embodiment, the projections 69c are three projections projecting from the routing structure 69 as shown in FIG. 6. However, the arrangement of the projections 69c is not limited to this, and any number of projections of any shape may be used. For example, the projections may alternatively be pins or bars that extend diametrically in the path.
[0077] Further, in the embodiment, the single protective tube 86 is fitted on the chain 83 as shown in FIG. 7. However, the arrangement is not limited to this, and the number of stoppers may be increased to fit a plurality of protective tubes on the chain.
[0078] The present invention exhibits the following effects due to the configuration described above.
[0079] According to claim 1, the chain includes the protective tube at the location thereof at which the chain is to contact with the fuel filler when the fill cap is removed. Consequently, damage to the fuel filler or the deck can be prevented and the chain itself can be prevented from causing damage thereto. As a result, fuel can be supplied without paying unnecessarily high attention to the fuel filler or the deck, and improvement in workability of the fueling operation can be anticipated.
[0080] According to claim 2, since the stopper for stopping movement of the protective tube is provided on the chain, the protective tube is retained at a necessary location of the chain. As a result, the protective tube can be partially attached to a location of the chain for which protection is required, and achievement of effective utilization of the protective tube can be anticipated.
[0081] According to claim 3, since the stopper is a bead integrally provided on the chain, movement of the protective tube on the chain can be stopped, for example, only by threading the protective tube onto the chain and attaching the fill cap to the chain. As a result, improvement in assembling property of the protective tube can be anticipated.
[0082] According to claim 4, since the stopper is formed as a slit washer that can be attached to the chain later, it is possible, for example, to thread a plurality of protective tubes onto the chain and attach the protective tubes at an arbitrary position of the chain with a slit washer later. As a result, expansion of the utility of the protective tube can be anticipated.
[0083] Although the present invention has been described herein with respect to a limited number of presently preferred embodiments, the foregoing description is intended to be illustrative, and not restrictive. Those skilled in the art will realize that many modifications of the preferred embodiment could be made which would be operable. All such modifications, which are within the scope of the claims, are intended to be within the scope and spirit of the present invention.
