Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a structure for a grab bar (assist grip) installed at the rear of a motorcycle.

(Prior art) Grab bars (assist grips) in motorcycles have traditionally been installed at the rear end of the seat rail of the vehicle body frame.]
・It is attached by tightening, but in order to improve the appearance decoration, it is known that a side cover that covers the side of the car body is placed on the outermost side so that the bolt tightening part is not visible from the outside. (For example, Japanese Patent Laid-Open No. 18470/1983).

However, in the conventional configuration described above, the left and right grab bars are integrated, and when the grab bar is removed for maintenance or repair work, the left and right side covers must be removed first, which reduces work efficiency. Not good.

In addition, if the lead force bar is mounted on the outside of the sieve and is made relatively large, the lower end of the grab bar passes through both outer sides of the side cover, penetrates a part of the side cover, and connects to the inner seat rail. need to be installed.

In this configuration, since the side cover is interposed between the seat rail and the grab bar attachment, there is a relatively large gap between the two. Therefore, to grab −
When installing a seat rail, a collar or the like is required to correct the above gap length, but if the left and right grab bars are integrated, and a collar is provided on the inner facing part of the lower end of the grab bar, the integrated grab bar Due to its rigidity, the space between the lower ends does not expand, so the grab bar cannot be removed with the side cover fixed. Therefore, when installing the grab bar, it is necessary to use a separate collar, etc., and assemble both the left and right sides in the same process using bolts from the inside where the seat rail is located. This results in poor performance and poor workability.

(Object of the Invention) The present invention has been made in view of the above-mentioned problems of the conventional art, and in the case where a grab bar is attached to a vehicle body frame by penetrating the cover from both outsides of the cover, the grab bar is divided into left and right parts. , the fastening parts such as bolts are not visible from the outside, and the exterior decoration can be improved.In addition, it is possible to improve the workability during maintenance and repair and the flexibility of the assembly process. The purpose of the present invention is to provide a grabber device for two-wheeled vehicles.

(Structure of the Invention) The present invention provides a grab bar device for a motorcycle that includes a grab bar attached to a seat rail of a vehicle body frame and a side cover that covers the side surface of the vehicle body. are located on both outsides of the side cover, and between the opposite inner side surface of the lower end of this grab bar and the seat rail,
゛It is fastened with a bolt inserted through a through hole provided in the side cover.

With this configuration, the grab bar can be removed without removing the left and right side covers during maintenance and repair work, and the left and right grab bars can be assembled in separate steps during assembly, improving work efficiency. .

(Embodiment) FIGS. 5 and 6 show a motorcycle equipped with a grab bar device as an embodiment of the present invention, in which 1 is a vehicle body frame, 2 is a pair of left and right pipe-shaped seat rails serving as the vehicle body frame, and 3 is a motorcycle equipped with a grab bar device. is the passenger seat, 4Q.

4r is a side cover that covers the left and right sides of the middle rest attached to the seat rail 2, and 5 is the side cover 40.4r.
A grab bar (assist grip) is attached to the rear end of the seat rail 2 through the grab bar 5. This grab bar 5 is a handgrip for moving the motorcycle or a hand grip for the passenger in the auxiliary seat when riding with two people. This is the result.

FIG. 1 shows a portion of the grab bar 5 and the side cover 4, FIGS. 2 and 3 show a first portion of the grab bar 5, and FIG. 4 shows a portion of the grab bar 5. The grab bar 5 consists of a left glove par 5Q and a right glove par 5r that are divided into left and right parts, and an intermediate member 51 that connects the two at the upper side. Side cover 4Q.

4r is attached to the seat rail 2 using brackets 6, bolts 7, etc. Above left and right grab bars 5ρ,
Lower end beam id cover 4Q of 5r.

/lr, and a female screw member 8 is fixed to the opposite inner side surface of the lower end. On the other hand, a bracket 1-9 is fixed to the rear end of the seat rail 2, and a bolt 10 is inserted from inside through the bolt hole of this bracket 9, and is inserted through the four through holes 11 of the side covers 4Q and 4r. By screwing into the female screw members 8 of the grab bars 5Q, 5r, the grab bars 5Q, 5r are fastened to the seat rail 2 with the side covers 4g, 4r interposed therebetween. A collar 12 is fitted to the outer periphery of the bolt 9 between the bracket 9 and the female threaded member 8, and a rubber bush 13 is fitted to the through hole 11 of the side cover 4Q, 4r, which the collar 12 comes into contact with. There is.

Further, as shown in FIG. 4, a right-hand thread 14 and a left-hand thread 15 of nt are formed at both ends of an intermediate member 510 interposed between the upper sides of the grab bar 5Q (5r).
A right-hand screw 16 and a left-hand screw (not shown) to which these right-hand screws 14 and left-hand screws 15 are screwed are provided at the upper end of Q (5r). A grab bar 50°5r is connected.

”-Since it is configured as shown, the grab bar 5Q,
5r mounting pole [- and color etc. are side cover 4Q
, 4r will not be placed inwardly and grow from the outside, and the exterior decoration requirements can be satisfied. Also, in the assembly process, the left and right grab bars 5R, 5r can be assembled in separate processes. , process freedom; W, workability is better than t. Furthermore, during maintenance and repair work, in the case of a left and right integrated grab bar as mentioned above, you have to remove the left and right side covers, whereas for a grab bar with a left and right split structure! M! , 5r, the grab bar 50 or 5r on only one side can be removed without removing the left and right side covers, and the work efficiency is improved.

The work of assembling and disassembling the grab bars 5Q and 5r is carried out by tightening or loosening the bolts 10 from inside the middle rest while listening to the seat 1-3.

Regarding the attachment structure of the grab bars 5ρ, 5r to the seat rail 2, in the above embodiment, the grab bars 50.
5r has a female threaded part +A8 fixed thereto, and a bolt 10 is screwed onto this from the inside of the bracket 9. A hole]~ is set upright on the surface, and this bolt is inserted into the exit hole 11. of the side cover 4j2.4r. Various types of fastening methods are possible, such as a configuration in which four bolt holes are passed through the bolt holes of the bracket 9, and the nuts 1- are screwed together on the inside of the bracket 1-9. f
f can be adopted.

(Effects of the Invention) As described above, according to the present invention, the grab bar has a right-side split configuration, and the lower ends of the left and right grab bars are extended to both sides of the side cover, and the opposing inner side surfaces of the lower ends are 1. It is fixed to the seat rail with a bolt inserted through the through hole of the side cover. 1. This prevents the bolts and other fixing members from coming off from the outside, improving the appearance decoration and improving the product quality (1.1 It is possible to increase the value, and it is also possible to remove the left and right side vehicle covers immediately for maintenance.
The grab bars can be removed, but the left and right grab bars can be assembled in separate steps, improving work efficiency.
