Description

[Detailed Description of the Invention] The present invention relates to a handlebar for a bicycle, and more particularly, to a handlebar having a brake operating tool mounted near a grip portion to be grasped during steering operation.

Conventionally, bicycle handles have been provided with handlebars that have a center part that extends in a substantially horizontal direction, and on both sides thereof, which extend upward in a vertical direction via upwardly curved parts, and whose upper part spreads outward.
It is known that a pair of upright parts are arranged in series, and an object such as a shopping basket is attached to the space between the central part and the compatible upper part.

However, according to the handle configured as described above, if a brake operating tool is attached near the grip part that is continuous to the above-mentioned upper part, and an operating cable attached to the brake operating tool is stretched along the above-mentioned upright part. However, there is a problem in that the operation cable becomes a hindrance when the attachment part is attached.

By the way, in the case of a normal flat bar type handle, when the operating cable is stretched along the handle, the insertion opening for the operating cable is placed near the grip part, and the insertion opening for the operating cable is placed near the attachment part of the handle to the handle stem. It is known that a handle is provided with an outlet for the operating cable, the operating cable is inserted into the handle through the insertion opening, and is pulled out from the outlet.

However, the insertion port and the outlet provided in the handle pass through one side of the handle, and the outlet cannot be seen from the insertion port, so the operation cable inserted into the handle cannot be seen from the outlet. There was a problem in that it was very difficult to draw out and required a lot of effort.

The present invention was devised in view of the above-mentioned problems, and consists of a pipe having a circular inner circumferential surface as described above, with the handle extending upward in the vertical direction through the central part extending in the horizontal direction and the curved part. In a U-shaped handle with an extending upright part, the insertion port is provided near the grip part, and when the operating cable is inserted from the insertion port toward the central part,
Due to the bending of the operating cable tip due to interference with the inner surface of the curved portion and the curved shape of the inner surface of the curved portion, slipping occurs at the interference portion between the operating cable and the inner surface of the curved portion, and the interference position is displaced and draws a predetermined trajectory. By focusing on the fact that the handle is curved, and by providing the outlet at a position that intersects the insertion locus of the operating cable, the operating cable inserted into the handle can be easily and quickly pulled out to the outside. The point is to make it possible.

Therefore, the structure of the present invention consists of a pipe with a circular inner peripheral surface, a central part extending in a substantially horizontal direction, and an upper part extending vertically upward from both sides of the central part via curved parts. A bicycle handle comprising a pair of raised parts extending outward and a grip part continuous to the upper part of the raised parts, and a brake operating tool is attached near the grip parts, wherein the brake operating tool is attached. An insertion port for an operation cable to be attached to the brake operating tool is formed near the part, and the cable is inserted through the insertion port in the tangential direction of the widthwise center of the upper side curved inner surface of the curved part. located in front, and
By providing an outlet for the cable at the center in the width direction of the lower circular inner circumferential surface in the central portion, by inserting the operation cable into the insertion opening, the interference position of the operation cable with the curved inner surface can be adjusted. The operating cable can be pulled out from the outlet while being displaced toward the outlet.

An embodiment of the handle of the present invention will be described below based on the drawings.

The illustrated handle has a central portion 1 extending in a substantially horizontal direction, and a pair of raised portions extending vertically upward from both sides of the central portion 1 via upwardly curved portions 2, 2, the upper portions of which extend outward. 3, 3 and the upper portions of the raised portions 3, 3 are provided with grip portions 5, 5 which are continuous via rearwardly curved portions 4, 4, and the grip portions 5, 5 and the rearwardly curved portion 4 are provided. , 4, the brake operating tools B, B are attached to the straight rod portion between the brake levers B and B. The handle constructed as described above is formed by using a pipe with a circular cross section and by bending this pipe.

In the handle configured as described above, this invention forms insertion ports 6, 6 for the operating cables K, K to be attached to the brake operating tools B, B near the mounting portions of the brake operating tools B, B, and
the cable K inserted from the front insertion ports 6, 6;
K is located forward in the tangential direction (direction of arrow z in FIG. 3) of the widthwise center portion 2b of the upper curved inner surface 2a, 2a of the upwardly curved portions 2, 2 in the insertion locus of K, and
The outlet ports 7, 7 for the cables K, K are provided in the widthwise central portion 1b of the lower circular inner circumferential surface 1a of the central portion 1.

In the above configuration, the insertion ports 6, 6 are located on the rear walls 3a, 3a at the upper part of the upright parts 3, 3.
It is formed by penetrating the Further, the insertion ports 6, 6 are inclined from the upper side to the lower side in the vertical direction with respect to the axis of the upright parts 3, 3.
Alternatively, it may be formed in a direction perpendicular to the axis. Note that the insertion ports 6, 6 may be provided in the rearwardly curved portions 4, 4.

Further, the outlet ports 7, 7 are inclined downwardly in the vertical direction from the axially outer side toward the inner side with respect to the axis of the central portion 1, but they may also be formed in a direction perpendicular to the axis. You may. As shown in the figure, protrusions 1c, 1c are provided at the inner opening ends of the outlet ports 7, 7 to prevent the operating cables K, K from passing over the outlet ports.

As shown in Fig. 1, the handle constructed as described above is constructed by attaching the central portion 1 at the longitudinally central position to the bar holder A provided at the top of the handle stem, and directing the upright portions 3 upward in the vertical direction. It is possible to attach an object c such as a shopping cart to the space between the central part 1 and the upright parts 3, 3, and a brake operating tool B near the grip parts 5, 5. , B, and connect the operating cables K, K to be attached to the brake operating tools B, B to the upright parts 3,
From the insertion openings 6, 6 provided at the top of 3 to the rising parts 3, 3
Outlet ports 7, 7 inserted into the central portion 1 and provided in the central portion 1;
It is pulled out from the outside.

Therefore, when the operating cables K, K are pulled out from the outlet ports 7, 7, the operating cables K, K inserted into the insertion ports 6, 6 have their tips bent downwardly into the upwardly curved portions 2, 2. , 2c, and due to the curved shape of the inner surface of the curved portion, slipping occurs between the operating cables K, K and the inner surface of the curved portion, and the interference position of the operating cables K, K is located at the outlet 7, 2c.
7, and due to this displacement, one side of the tip side of the operating cables K comes into contact with the widthwise center portions 2b, 2b of the upper curved inner surfaces 2a, 2a of the curved portions 2, 2. While the operating cables K, K are bent around this contact position, the interference position of the tip of the operating cable is aligned with the outlet 7, 7.
The operating cables K, K are displaced to the widthwise center portion 2 of the upper curved inner surface 2a, 2a.
It curves along a predetermined trajectory around the contact position with b, 2b, fits into the outlet 7, 7, and exits to the outside. Therefore, the operating cables K, K inserted into the insertion openings 6, 6 can be pulled out from the extraction openings 7, 7.

As described above, the present invention consists of a pipe with a circular inner circumferential surface, a central part that extends in a substantially horizontal direction, and a pipe that extends vertically upward from both sides of the central part via curved parts, and has an upper part that extends outward. The brake operating tool is installed near the attachment point of the brake lever on the handle, which includes a pair of raised parts that extend across the handle and a grip part continuous to the upper part of the raised parts, and the brake operating tool is mounted near the grip parts. forms an insertion opening for an operation cable to be attached to the insertion opening, and is located tangentially forward of the center in the width direction of the upper side curved inner surface of the curved part, and Since the cable outlet is provided at the center in the width direction of the lower circular inner circumferential surface of the section, by applying an insertion force to the operating cable inserted into the insertion port, the operating cable is pulled out by the curved inner surface of the curved section. The interference position with the curved inner surface is displaced in a direction approaching the outlet, and one side of the middle part of the operating cable comes into contact with the widthwise center part of the upper curved inner surface in the curved part, and this contact position is The interference position is displaced to the outlet position while being bent around the center, and the tip of the operating cable is fitted into the outlet. Therefore, the operation cable can be pulled out from the outlet by simply applying an insertion force to the operation cable inserted into the insertion opening, and the operation cable can be pulled out easily and quickly. It is.

Moreover, since the tip of the operating cable inserted into the insertion port can be guided naturally to the outlet, the diameter of the outlet can be made small, for example, to be slightly larger than the outer diameter of the operating cable, and therefore the handle can be easily pulled. This makes it possible to reduce the decrease in strength due to the exit.
