JPS5849903Y2 - Lever handle for operating wire - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lever bundle for an operating wire, such as a brake lever bundle for a bicycle, for pulling an operating wire.

The button for this type of lever bundle is made by drawing a single metal plate and continuously forming a gripping part with an arc-shaped cross section and a mounting part with an inverted U-shaped cross-section into an abbreviated shape. At the end, the end is squeezed so as to cover the end to prevent injury, and the lower edge abutting part is processed so that it fits tightly.

In other words, the terminal will face the handle grip side of the bicycle on which this lever bundle is installed, but when or after holding the grip with your fingers, the back of your finger may touch the terminal and cause an unexpected injury. Let's do it.

For this reason, the above-mentioned processing is performed, but this processing is time-consuming, and during plating, the plating solution stays in the grip, making it impossible to achieve uniform plating, which can lead to corrosion. existed.

The present invention has been made to improve this inconvenience, and is formed by a simple drawing process, and the unprocessed part is covered by an insert part attached to this, so that the drawing process is automatically formed. It has been made possible.

To explain this with respect to the embodiments shown in FIGS. 1 to 5, reference numeral 1 indicates a lever bundle, and the lever bundle 1 is formed by drawing a single metal plate to form a grip portion 1a having a substantially C-shaped cross section and a grip portion 1a having a substantially C-shaped cross section. The inverted U-shaped mounting portion 1b is continuously molded into an abbreviated shape, and the gripping portion 1a has a cross-sectional shape of a substantially C-shape with a gap 2 at the lower edge as shown in FIG. At the same time, its terminal is formed at the open end 3.

Therefore, the lever handle 1 can be easily formed using an automatic drawing machine and can be plated uniformly without the plating solution remaining inside the gripping portion 1a.

However, the end opening 3 and the gap 2 at that time are dangerous and unpleasant to the lever bundle, and correspond to an unprocessed part of the bundle. A synthetic resin insert member integrally formed with a spherical part 4 to abut on the end 3, an engaging part 5 to engage in the gap 2, and a clamping part 6 clamped on the inner surface of the mounting part 1b. 7 was fitted.

However, the insert member 7 is provided with a through hole 9 in the clamping part 6 that coincides with the shaft support hole 8 of the nozzle 1, so that the shaft support pin inserted into the through hole 9 is locked to prevent it from coming out. It has become.

In this case, the insert member 7 may be integrated with the bundle 1 using an adhesive instead of using the above-mentioned pivot pin.

The gap 2 at the lower edge of the gripping part 1a is an inverted U-shaped mounting part 1b.
Therefore, the thickness of the insertion member γ is also formed to be approximately the same width as the gap 2, and its insertion also serves to reinforce the continuous portion between the gripping portion 1a and the mounting portion 1b. Further, the outer edge of the insertion part 7 has a flange body 10 that covers the gap,
The engaging portion 5 is formed with an engaging protrusion 5at5b formed between the flange body 10 and the same distance as the thickness of the metal plate.

In the figure, 11 indicates a wire attachment hole.

As described above, according to the present invention, the gripping part 1a of the lever handle 1 has a cross-sectional shape of a substantially C-shape with a gap 2 at the lower edge, and its end is formed into an opening 3. Since this can be formed by a simple drawing process, it is impossible to automate the process, so it is produced in large quantities, and the plating process is easy and inexpensive, and the
The handle 1 is made of synthetic resin and is integrally formed with a spherical part 4 that contacts the open end 3, a retaining part 5 that engages with the gap 2, and a clamping part 6 that is clamped on the inner surface of the mounting part 1b. Since the insert members are fitted together, the unprocessed part due to the drawing process is completely covered, so that it is possible to obtain a lever handle that is pleasant to the touch and is not dangerous.
