Abstract

PURPOSE:To provide a bar handle having large rigidity, simple constitution, and no need of complicate construction for fitting members on a body side. CONSTITUTION:The clamp part 15 of a handle pipe 11 is made thicker than a grip part 14, and it is gradually changed the form to the grip part 14 through a contract part 16 tapering off. The clamp part 15 itself has large strength against force in any direction. Further, it can do without separately providing a reinforcing member such as a bridge, interference due to the bridge generated in case of a customary one can be eliminated, and hence there is no need to forcedly adopt complicate construction for fitting members on a body side.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to motorcycles, A
The present invention relates to a bar handle used for vehicles such as a TV (saddle-type off-road vehicle), a snowmobile, or a jet ski (water vehicle).

2. Description of the Related Art Conventionally, there are bar handles shown in FIGS. 11 to 13 as examples of bar handles used for motorcycles and the like. In these figures, 1 is a handle pipe with both ends bent in the same direction with respect to the center,
Both ends constitute a grip part 2, and a throttle grip 3, a brake lever 4, etc. are attached to this grip part 2. Further, the central portion constitutes a clamp portion 5 that is attached to the vehicle body side. The handle pipe 1 is supported on the vehicle body side by tightening the clamp portion 5 with a clamp 7, a bolt 8, and a washer 9 on an upper bracket 6 fixed to the vehicle body side. Note that the handle pipe 1 has a bridge 10 that bridges the clamp portion 5.
is fixed at both ends by welding, brazing, or screwing, reinforcing the handle pipe 1.

[Problems to be Solved by the Invention] However, in the handle pipe 1 described above, the bridge 10 is easily bent, and
By providing the bridge 10, there is a problem in that the upper bracket 6 must be constructed so as not to interfere with the bridge 10, and the upper bracket 6 is forced to have a complicated structure. Also, bridge 1
0 and the clamp part 5 are lined up (vertical direction in FIG. 11), but the force in the orthogonal direction (FIG. 11
Its strength was low against forces (in the front and back directions), and it was easy to bend when subjected to forces in this direction.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a bar handle that has great rigidity, has a simple structure, and does not require a complicated structure for the mounting member on the vehicle body side. purpose.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a bar handle in which grip portions are provided at both ends of the handle pipe and a clamp portion is provided in the center portion, and the clamp portion of the handle pipe is provided. It is characterized in that the clamp part is made thicker than the grip part, and the clamp part gradually becomes thinner so as to be connected to the grip part.

[0006]

[Operation] Since the present invention is constructed as described above, the clamp portion itself has great strength regardless of the direction of the applied force. Further, by making the clamp part itself strong, it becomes unnecessary to separately provide a reinforcing member such as a bridge.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 7 and 10. In the figure, 11 is an upper member 12 and a lower member 1 obtained as described below.
This is a handle pipe made of steel or aluminum alloy. This handle pipe 11 is provided with grip portions 14 of a predetermined diameter at both ends thereof, and is provided with a clamp portion 15 thicker than the grip portion 14 in the center via a reduced portion 16 which is gradually tapered. The handle pipe 11 is fixed to the vehicle body by attaching the clamp portion 15 to an upper bracket 19, which is fixed to the vehicle body (not shown) via bolts 17 and washers 18, using bolts 20 and washers 21. Further, a throttle blip 22, a brake lever 23, etc. are attached to the grip portion 14.

[0008] The upper member 12 and the lower member 13
is obtained by press working, and as shown in FIG. 3, the handle pipe 11 in the shape of an irregular pipe is obtained by welding them together in a mona-naka manner (so-called mona-ka structure).

Note that the handle pipe insertion hole 24 formed in the handle pipe 11 and the upper bracket 19
The size of is set as follows. That is, Figure 5
As shown in FIG. 4, the width W of the clamp portion 15 from the end of the clamp portion 15 is set within a circle 25 having a diameter corresponding to the diameter of the handle pipe insertion hole 24, as shown in FIG. ing. By setting the dimensions in this way,
Handle pipe insertion hole 24 of upper bracket 19
The handle pipe 11 can be passed through the handle pipe 11 from the side, which eliminates the need to separately provide the clamp 7 on the upper bracket 19 (separate type) when attaching the handle pipe 11, as shown in FIG. 13 mentioned above. will disappear.

In the bar handle constructed as described above, the clamp portion 15 of the handle pipe 11 is formed through the tapered portion 16 and has a larger diameter than the grip portion 14, so that the bar handle is more effective than the conventional one. It has great strength regardless of the direction of the force, and will not bend easily even if it is subjected to force from various directions. Also,
Compared to those shown in FIGS. 11 to 13, no bridge is provided, and since there is no interference caused by this, the upper bracket 19 is not forced to have a complicated structure.

[0011] In place of the above-mentioned handle pipe 11 having a so-called monochrome structure, a handle pipe formed by a hydraulic press as shown in Figs. 8 and 9 may be used. This product is made by injecting high-pressure liquid into a pipe 27 made of steel or aluminum alloy with one side blind 26, press-forming the pipe 27 with a lower mold 28 and an upper mold 29, and molding the pipe 27 as needed. It is obtained by subjecting it to heat treatment, surface treatment, etc. Note that, like the handle pipe 11 described above, this pipe also has grip parts 30 of a predetermined diameter at both ends, and a clamp part (with a diameter larger than the grip part 30) in the center part.
(not shown) is provided through a tapered part (not shown), so that it does not easily bend even if it receives forces from various directions.

0012

[Effects of the Invention] In the present invention, the clamp part of the handle pipe is formed through a tapered part and is made thicker than the grip part, so it has great rigidity and can easily handle forces from various directions. There is no bending. Even greater rigidity is achieved with a simple structure, eliminating the interference caused by the bridge that occurs with conventional ones, and thereby eliminating the need for a complex structure for the mounting member on the vehicle body side.
