Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rear stay that is provided so as to surround the rear of the seat from the left and right side surfaces of the lower part of the seat of a motorcycle.

In general, motorcycles are provided with grab bars that extend rearward from both left and right sides of the lower portion of the seat and surround the rear of the seat. The above-mentioned grab bar is held by two people riding together, or when the vehicle is stopped, when it is placed on a stand, or when the vehicle is pulled around.

Conventionally, the grab bars mentioned above have been made of pipe material or cast aluminum material bent into an almost U-shape.The model can be changed by changing the seat shape, or a common model with only the seat shape is sold. In this case, it is necessary to design the shape of each grab bar, which has the disadvantage of making manufacturing complicated and increasing costs.

The present invention has been made based on the above-mentioned circumstances, and it is an object of the present invention to provide a grab bar for a motorcycle that has a high degree of freedom in shape selection and is inexpensive to manufacture.

In order to achieve the above object, the present invention provides a motorcycle in which a grab bar is attached to the vehicle body so as to surround the upper left and right sides of the lower part of the seat and the upper part of the rear part of the seat. It is characterized in that the left and right side parts are fixed to the vehicle body, and both ends of the rear part are detachably connected to the left and right side parts.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

In FIG. 1, reference numeral 1 designates a pair of left and right seat rails (only one of which is shown) constituting the body of a motorcycle, and 2 designates a backstay that also comprises a left and right pair (only one of which is shown). A seat 3 is mounted on the seat rail 1. A rear fender 4 is provided below the seat 3 and located between the left and right seat rails 1. Note that the rear end of the seat rail 1 is flattened to form a fixed part 5,
Further, a bracket 6 is welded to the joint between the seat rail 1 and the backstay 2.

However, 7 is a grab bar, and the above seat 3
It is formed to extend rearward from the left and right side surfaces of the lower portion and to surround the upper part of the rear portion of the seat 3. As shown in FIGS. 2 and below, the grab bar 7 is divided into three parts: left and right side parts 8, 8, and a rear part 9.

The left and right side parts 8, 8 of the grab bar 7 are symmetrical to each other, and are press-formed from a carbon steel plate or rolled steel plate to have a substantially C-shaped cross section as shown in FIG. The surface is chrome plated. A fixed seat part 10 is formed at one end of the left and right side parts 8, and a notched connecting hole 11 is formed in this fixed seat part 10. Note that a reinforcing plate 12 is welded to the inside of the fixed seat portion 10. Further, a connecting bracket 13 is welded to the middle of the left and right side parts 8, and a fixing hole 14 is bored in this bracket 13. A fixing plate 15 is welded to the inside of the other ends of the left and right side parts 8,
Insertion holes 16 as shown in FIG. 7 are formed between this plate 15 and the left and right side portions 8. As shown in FIG. Bolt insertion holes 17 and 18 are formed in the fixing plate 15, and one of the insertion holes 18 is a long hole.

The rear part 9 of the grab bar 7 is also press-formed from carbon steel or rolled steel plate, and has a cross section that is approximately U-shaped as shown in FIG. material 20 and this core material 2
0 and a covering material 21 covering the 0. The covering material 21 is made of an elastic material such as vinyl chloride foam, and the core material 20 is molded therein. Both ends of the core material 20 protrude from the covering material 21, and these protruding parts are adapted to be inserted into the insertion holes 16 of the left and right side parts 8, 8. Connecting holes 22, 22 are bored in the protruding portion of the core material 20, and nuts 23, 23 are provided on the inner surface of the connecting holes 22, 22.
is welded. Therefore, both ends of the core material 20 are inserted into the insertion holes 16 of the left and right side parts 8, 8, and the bolts 24, 24 are inserted into the insertion holes 17, 18, 2.
By screwing into nuts 23, 23 through 2, 22, it is removably connected to the left and right side parts 8, 8, whereby the rear part 9 and the left and right side parts 8, 8 are integrally connected. In this case, the edges of the left and right side parts 8, 8 are fitted into entry holes 25 formed in the end faces of the covering material 21, as shown in FIG. 7, so that the end faces are hidden.

The grab bar 7, in which the rear part 9 and the left and right side parts 8, 8 are integrally connected in this way, has its connecting hole 11 at one end implanted into the bracket 6 on the vehicle body side, as shown in FIG. It is attached to the vehicle body by engaging a bolt, fixing with a nut 26, and fixing the fixing hole 14 of the connecting bracket 13 to the fixing part 5 of the seat rail 1 with another bolt 27.

In the configuration of the embodiment described above, the grab bar 7
The core material 20 of the left and right side parts 8, 8 and the rear part 9 is made of pressed sheet metal, and is formed into a C-shape and a U-shape in cross section, respectively, so it is hollow and lightweight, yet strong. is a large one. In addition, press processing is excellent in mass production, and materials can be obtained at low prices, so manufacturing costs are low. Such press-formed products have a large degree of freedom in selecting the cross-sectional shape.

Further, the rear part 9 of the grab bar 7 is formed with a covering material 21 of the core bar 20, and since this covering material 21 is made of an elastic material such as vinyl chloride foam, it is soft and feels good when gripped. Not easy to slip. In particular, the covering material 21 is not restricted by the shape of the core bar 20, is thick, and has a cross section that can be freely selected, making it easy to grip. Moreover, the appearance of the covering material 21 can be improved by coloring it.

In addition, although the case where the rear part 9 of the grab bar 7 was comprised by the core metal 20 and the covering material 21 in the above case was demonstrated, this invention is not restricted to this. That is, for example, FIG. 8 shows another embodiment of the present invention, and the rear part 80 of the grab bar in FIG. , 82 are welded together, and the horizontal rod 81 is curved into a substantially U-shape and has a chrome-plated surface. The connectors 82, 82 have the same structure as the protruding portion of the core bar 20 in the embodiment shown in FIG. This product is easy to manufacture because all parts are made of sheet metal, and the cost is low.

In the case of the configuration shown in FIG. 8, it is also possible to cover the rear portion 80 of the grab bar with an anti-slip tube made of synthetic resin or the like.

In addition, in the case of the configuration shown in FIG. 8, it is also possible to select an embodiment in which only the horizontal rod 81 of the rear part 80 of the grab bar has a different cross-sectional shape from the left and right side parts 8, 8, and this shape is selected to be easy to grip. becomes.

As described in detail above, the present invention provides a motorcycle in which a grab bar is attached to the vehicle body so as to surround the upper part of the rear part of the seat from the right and left side surfaces of the lower part of the seat, in which the grab bar is divided into left and right side parts and a rear part. It is characterized in that the side parts are fixed to the vehicle body, and both ends of the rear part are detachably connected to the left and right side parts. Therefore, since the grab bar is divided into three parts, it is not only easy to process these parts, but also the shape of the rear part of the grab bar can be freely selected to suit the shape of the seat without changing the left and right sides. It has the effect of being easy to do.
