Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an operating lever used for a brake lever for a motorcycle, etc.

(Prior Art) As a brake lever for a two-wheeled vehicle, it is composed of a cored bar and a synthetic resin cover, and a base part having a shaft supporting part and a grip part are integrally formed in a substantially L-shape on the cored bar. Is integrally formed with a pair of holding portions that hold the base portion from both sides and a cylindrical portion that is capped on the grip portion, and a pivot pin for pivotally supporting the handle-side bracket is attached to the support portion and the pair of holding portions. Japanese Patent Laid-Open Publication No. Sho 56-31502 has already provided a structure in which a core metal and a synthetic resin cover are inserted into a holding portion so as to be prevented from coming off.

(Problems to be solved by the invention) In this case, since the core metal and the cover are manufactured separately, and the cover is capped on the core metal, they are retained by the shaft support pin, so both are retained by the brake lever. Is carried out at the time of pivotally supporting on the bracket of the handle, and therefore, there is a drawback that the cored bar and the cover cannot be handled as an integrated complete product before the assembling work.

(Means for Solving the Problem) The present invention provides an operation lever in which a cored bar and a synthetic resin cover can be combined and retained in advance, and the structure is simple and the manufacturing is easy. Is something that
As a specific means therefor, a cored bar (15) and a synthetic resin cover (16) are provided, and the cored bar (15) includes a base (19) having a shaft support (18) and a grip (20). Is provided in a substantially L shape, and the synthetic resin cover (16) has a pair of holding portions (22) for holding the cylindrical portion (21) capped with the gripping portion (20) and the base portion (19) from both sides. ) (23) and the operating lever provided with, the one of the holding portion (22) formed along one side surface of the shaft support (18), the shaft support (18)
The washer (26) along the other side is integrally provided via the bendable portion (25), and the washer (26) is fitted and locked in the shaft hole (17) of the shaft support (18). The fitting portion (27) is provided integrally.

(Function) After manufacturing the core metal (15) and the synthetic resin cover (16), the core metal (15)
Cover the cover (16) with the cover (16), bend the one bent portion (22) to the holding portion (22), and attach the washer (26) to the shaft support (18) of the cored bar (15).
Along with the other side of the washer (26)
The 7) is fitted and locked in the shaft hole (17) of the shaft support (18). This is the core
The (15) and the cover (16) can be securely retained and can be handled as one complete product.

(Embodiment) The present invention will be described in detail below with reference to the illustrated embodiment.
In the figure, (1) is the handle of the bicycle and (2) is its grip. Reference numeral (3) is a hollow bracket, which is attached to the handle (1) via a fastener (4). Reference numeral (5) is a brake lever, which is pivotally supported by a pivot pin (7) inserted through a pair of side walls (6) of the bracket (3), and the brake lever (5) has an inner ( 9) are connected via a connector (10) and a pin (11). The outer (12) of the Bowden wire (8) is attached to the bracket (3) via the metal fitting (13).
It is fixed to. (14) is a stopper for the brake lever (5).

The brake lever (5) is composed of a core metal (15) made of sheet metal or the like and a cover (16) made of synthetic resin. As shown in FIG. 2, a base (19) having a shaft support (18) with a shaft hole (17) and a grip (20) are integrally formed in the core metal (15) in a substantially L-shape. There is. Further, the cover (16) is, as shown in FIG.
A tubular part (21) to be capped on (20) and a pair of holding parts (22) and (23) for holding the base part (19) from both sides are integrally formed. One of the holding parts (22) (23), the holding part (22)
One washer part (24) along one side of the shaft support part (18)
Are integrally formed with each other, and the other washer portion (26) is integrally formed with the washer portion (24) through the bent portion (25). Bend (2
5) is formed in a flexible belt shape. The other washer (2
6) is for fitting along the other side surface of the shaft support part (18), and this has a tubular fitting part (27 ) Is formed.

With such a structure, by fitting and locking the fitting portion (27) of the washer portion (26) in the shaft hole (17) with the cover (16) covered with the core metal (15), Both can be retained. That is, as shown in FIG. 4, the grip portion (20) of the core metal (15) is connected to the cylindrical portion (2) of the cover (16).
1), and with one washer part (24) along one side of the shaft support (18), bend the bent part (25) to bend the other washer part (2).
6) is aligned with the other side surface of the shaft support (18), and the fitting portion (27) is fitted and locked in the shaft hole (17). As a result, as shown in FIG.
Since the (15) and the cover (16) are in a state of being prevented from coming off, it can be handled as an integrated complete product before or without the connecting tool (10).

When attaching the brake lever (5) to the bracket (3),
As shown in FIG. 6, the washer portions (24) and (26) on both sides of the shaft support portion (18) are positioned between the pair of side walls (6), and the shaft support pin (7) is inserted therethrough. In this case, since the washers (24) (26) are integrated,
It is not necessary to install it separately, it is easy to assemble, and the fitting part
(27) also functions as a bush.

The fitting portion (27) is provided on the washer portion (26) side, and as shown in FIGS. 7 and 8, the fitting portions (27a) (27a) (27a) (27a) (27) are formed on both washer portions (24) (26).
b) is integrally formed, and when fitted in the shaft hole (17) of the shaft support (18), both fitting parts (27a) (27b) become cylindrical in the shaft hole (17). You can also do it.

It goes without saying that this lever can also be used for something other than the brake lever (5).

(Effect of the Invention) In the present invention, the fitting portion (27) of the washer portion (26) integrally formed on the one holding portion (22) via the bent portion (25) is provided with the shaft hole of the shaft support portion (18).
Since it is designed to fit and lock with (17),
It is possible to prevent the 5) and the cover (16) from coming off, and the subsequent handling is easy. Further, since the washer portion (26) and the fitting portion (27) are integrated with the holding portion (22) through the bent portion (25), these can be formed at the same time when the cover (16) is formed,
The structure is simple and easy to make. Furthermore, since the washer part (26) is integrated, a separate washer is not required and the bracket
(3) Easy to install.
