Description
Background of the Invention
The present invention relates to a rear structure for motorcycles.
In a rear structure for a motorcycle, there are provided a rear trunk, a backrest mounted on a front side of the rear trunk, and a headrest (if desired). In such a structure it is general that even if the backrest is mounted independently, the backrest is not higher than an top surface of the rear trunk. If the headrest is provided or instead thereof the height of the backrest is increased for the purpose of enhancing a touring feel, the rear space defined by the headrest or the backrest should be effectively utilized.
On the other hand, the rear trunk of the motorcycle is generally utilized for receiving therein various sized articles and tools together. In particular, there is a demand that a utility box for small articles such as a vanity set be provided in the rear structure for female riders.

Detailed Description of the Preferred Embodiments
The present invention will now be described with reference to the accompanying drawings. In FIGS. 1 and 2, there is shown a rear structure for a motorcycle 1. A rear seat 3 is provided on the rear side of a front or driver's seat 2. A backrest 5a is provided at a rear side of the rear seat 3 for the sake of ensuring good riding feel and safety. The backrest 5a is secured to a front surface of a rear trunk 5 fixed to a motorcycle body frame 4. A pair of armrests 6, 6 are provided on both sides of a backrest 5a. The armrests 6, 6 are constructed so that elbows of the rear rider (indicated by dot-and-dash lines in FIG. 1) may be kept in a natural form. The armrests 6, 6, are preferably formed in a detachable fashion to be described. Various detachable structures of the armrests per se well known in the art are applicable. For example, the armrest structure may include a hinge mechanism (not shown) by which the armrests 6, 6 may be rotated, as desired, with respect to the frame 4, and the armrests may be turned back when the armrests are not used.
An open type armrest structure according to the invention will be described with reference to FIG. 3A. In FIG. 3A, the box 7a for receiving therein articles is fixed to the rear trunk by screws 7d, 7e. However, it is also possible to integrally form the box with rear trunk. Bearing seats 7a', 7b' are formed on the box 7a. As shown in FIG. 3A, support pins 7b', 7b' of an openable lid or cover 7b are carried on the bearing seat 7a', 7a'. Thus, the openable cover 7b is upwardly swingable. Furthermore, a fastening plate 7c for supporting the openable cover 7b and the box 7a are fixed together by screws 7e whereby the armrest 7 as a whole is fixed.
FIG. 3B shows a modification of the armrest structure shown in FIG. 3A. The structure shown in FIG. 3B including a hook engagement structure having a groove 7d and a projection 7e formed in the box 7a and an associated structure having a groove 5b and a projection 5b formed in the trunk 5. On the other hand, a screw-and-nut structure having a screw 7f and a nut 5d for fastening the armrest 7 to the trunk 5 is provided at a top portion of the trunk 5. With such a construction, the attachment/detachment of the armrest 7 may readily be carried out.
In another type armrest structure according to the present invention shown in FIGS. 4A and B, a pair of armrests 6, 6 are provided on both sides of the backrest 5a. As shown in FIGS. 4A and B, an upwardly opened box-shaped case 6a is formed integrally with the rear trunk 5. A box 6b is slidingly moved, as indicated by the arrows, on the box-shaped case 6a like a drawer. An armrest portion 6c which has cushion material such as sponge or rubber on its upper side is provided on the upper surface of the case 6a. Also, to prevent the box 6b from falling appart from the case 6a, a stop member 6d such as a leaf spring is secured on the case 6a side. A spring stop 6e fixed to the box 6b is engaged with and disengaged from a hole 6a' formed in the bottom surface of the case 6a whereby the receiving position is determined.
Referring now to FIG. 5, a rear trunk structure according to the invention will be described in detail. The rear trunk structure 5 comprises a box 11 fixed through damper members 105 to a mounting seat 104 of the motorcycle body frame 4 and an openable cover 112 hinged at a location 106 about the box 111. A backrest 113 which is higher in level than a top surface of the cover 112 is provided on the front side of the openable cover 112 and is rotatable together with the cover 112. An article receiving portion 114 is formed in a space corresponding to a height, of the backrest, exceeding the top surface of the cover 112. The article receiving portion 112 is formed in a triangular shape in cross section as shown. However, the portion 114 is not limited thereto. The openable cover 112 is integrally formed with the backrest 113 and the article receiving portion 114.
On the article receiving portion 114, there is provided a partitioning member 114a for partitioning the article receiving portion 114 from the cover 112. The partitioning member 114a is rotatably mounted at a hinge 114d. On the outer surface of the partitioning member 114a, there is further provided a smaller lid 114b which is also rotatably mounted on the partitioning member 114a. A mirror 114c a size of which is substantially the same as that of the openable lid 114b is built in the partitioning member 114a. The mirror is usefull for dressing. When the openable cover 112 is opened as indicated by a solid line in FIG. 5, the partitioning member 114a is exposed. Then, the partitioning member 114a is opened for taking a necessary particle and is again closed. When the lid 114b is opened, it is possible to see the mirror 114c from a direction as indicated by the arrow A. Incidentally, as another use of the structure, instead of the mirror 114c, a reflector such as a stop mark at night may be used.
Such a structure allows the following additional arrangement. Since the rear trunk 5 may be enlarged in size, as shown in FIG. 2, electric means such as stop lamps 107 and reflectors 107a may be mounted in a unit fashion on a rear lower portion of the rear trunk 5. Thus, a double row arrangement may be attained together with a conventional arrangement composed of electric means such as stop lamps 107 and turn signal lamps 109 and reflectors 107a disposed therebetween. As shown in FIG. 6, since the stop lamps 107 and the tail lamps and the like are arranged at the rear side of the rear trunk 5, a visible ability of a vehicle running after the motorcycle is much more enhanced.
Also, conventionally, when a rider's helmet is out of use, it is suspended from a suitable position on one side of the motorcycle body. In such a structure, when a plurality of motorcycles are arranged in parallel for parking, the parking space much wider than expected is required. To obviate such a defect, according to the present invention, helmet locks 110 are located at the rear side of the rear trunk as showing in FIG. 6.
