Manipulate production methods bakelite handle

        In general, the more the joystick bakelite bakelite handle tube bending, and the bakelite joystick to operate the shaft (sleeve) is welded to the sheet metal press working from the coupling elements, in order to ensure the strength, the erection of the bridge between the two handle member, but even so, the bridge member can be easily bent, so as to avoid interference with the bridge-shaped member, you must set the bracket and so on.
Therefore, there will bakelite bakelite handle joystick central tube clamping portion made thicker than the handle portion, and extends through the narrow portion gradually tapered to the example of the shape of the handle portion.
        As constituting such a shape, in this embodiment, the tube made of bakelite handle upper and lower halves separated, and each combination of pressure after processing into construction, while injecting high pressure fluid in one side of the tube is clogged while the tube is less pressure forming mold and the upper mold.
        In this process, since the upper and lower halves, respectively, are pressurized, and the need for welding assembly, so that more processing time; in the latter method, the pressure must be specially processed, no matter what kind, and for the sleeve combined with mounting bracket must increase the number of parts.
        The present invention was made in view of this point and its object is to provide a small number of parts, easy molding and processing, and can obtain sufficient strength bakelite joystick.
To achieve the above object, the present invention joystick bakelite plate-like member is formed into a generally U-shaped in cross-section rod, also formed integrally to the vehicle mounting portion mounted on the shaft of the operator.
        Since the plate-shaped member is a rod made of a substantially U-shaped in cross-section, the processing performed by the pressure molding processing becomes easy.
        Further, the U-shaped cross section, to ensure the strength.
        Since the operation of a vehicle mounting portion in the axial direction are also integrally formed mounting, a reduced number of parts, assembling work easy.
        The invention described in claim 2 characterized in that in claim 1 described bakelite joystick, the joystick bakelite section along said U-shaped opening surface formed with a flange.
        The flange may be integrally formed simultaneously with the body, and thus easy to process, and may be further enhanced by the strength of the flange.
        Without large pressure equipment, about half were easy forming process, the strength is fully guaranteed.
The invention described in the claims, characterized in that in the account of one or two joysticks claims bakelite, bakelite joystick on said integrally formed bakelite handlebar mounting portion.
        In another conventional structure were single handlebar bakelite bakelite handle mounting brackets made of cast aluminum and the like manufactured, installed, must be processed bay itself processing, drilling, tapping, and thus high costs and needs to be fixed to the pipe with bakelite handles bakelite handles and other parts, parts management to carry out the assembly work also increased, but if the joystick is integrally formed bakelite bakelite handlebar mounting portion, without these parts management and assembly jobs , is expected to reduce costs.
        The invention described in claim 5, characterized in that, as described in Bakelite steering handle, bakelite handle on said fixed portion integrally formed with the operating cable.
Since the operating handle and bakelite handle bar while operating cable is formed integrally with the fixed portion, without this aspect parts management and assembly operations, is expected to further reduce costs.
