Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device for switching an object to be operated via a wire, such as an operating/stopping operating device for a swinging mechanism in an electric fan.

The embodiments of the present invention shown in FIGS. 1 to 5 will be described in detail below.

Reference numeral 1 denotes a substrate made of a metal plate, for example, a steel plate, and has a shaft forming hole 2 and retaining holes 3, 3 located opposite to each other with the hole 2 in the center.
A hole 4 for forming a member, a notch 5 for forming a member, and a board mounting hole 6 are formed.

Further, on the upper surface of the substrate 1, a plurality of locking portions 7, 7, for example, two locking portions 7, are formed at appropriate intervals on an arc line drawn around the center of the shaft forming hole 2.

Reference numeral 8 denotes a support shaft integrally molded with synthetic resin on the substrate 1, spanning the shaft molding hole 2 and the retaining hole 3゜3, with the portion located in the shaft molding hole 2 serving as the shaft portion 8a. It has a threaded hole 9 passing through it vertically, and the portion located in the retaining holes 3, 3 becomes the retaining portion 8b of the support shaft 8.

Reference numeral 10 indicates a hole 4 for forming a member and a notch 5 for forming a member in the substrate 1.
The upper surface of the supporting member is integrally molded from synthetic resin and has a fitting groove 11 into which the end of an outer tube (described later) fits, and screw holes 12 located on both sides of the groove 11. 12.

Further, the inner surface of the fitting groove 11 of the support member 10 has a plurality of locking grooves 13.degree. 13 at appropriate intervals in the axial direction.

The support shaft 8 and the support member 10 are molded by placing the substrate 1 at a predetermined position in a mold, and then injecting a synthetic resin solution into the mold and curing it.

Reference numeral 14 designates a lever-shaped operating body that is rotatably fitted to the outer periphery of the shaft portion 8a of the support shaft 8 with its center portion, and an operating knob (not shown) is attached to one end of the lever-like operating body, and a lever-shaped operating knob (not shown) is attached to the other end. is connecting pin 1
5, and a holding hole 16 is bored at a position that can face the locking portion 7.7.

Numeral 17 is a plate spring that overlaps the upper surface of the operating body 14 and is rotatably fitted to the outer periphery of the shaft portion 8a of the support shaft 8.
The steel ball 18 located at is urged toward the substrate 1 side, and the steel ball 18 is engaged with and disengaged from the locking portions 7, 7 by the rotating operation of the operating body 14.

19 is a fixing screw screwed into the screw hole 9 of the shaft portion 8a,
The operating body 14 and the leaf spring 17 are maintained in a fitted state.

20 is a wire that connects one end to the connecting pin 15 of the operating body 14 and the other end to the oscillating mechanism (not shown) of the electric fan, which is the operated body, and connects the end of this outer tube 21 to a support member. 10 fitting grooves 11, and its collar 22 is locked in a suitable one of a plurality of locking grooves 13.13.

A fixing screw 23 is screwed into one of the screw holes 12, 12 of the support member 10 to maintain the fitted state of the outer tube 21.

Note that 24 and 24 are stoppers formed by bending the base plate 1 to restrict the rotation range of the operating body 14, and 25 are screws for attaching the base plate 1 to the inner surface of the base (not shown) of the electric fan.

Then, the operating body 14 is rotated to move the steel ball 18 to the locking portion 7.
, 7, the operating body 14 locks and holds the wire 20 in a tensioned state or a relaxed state, and in each state, the swinging mechanism is stopped or activated via the wire 20. It is used to switch the state.

Note that the regulating pieces 24, 24 are formed by forming a forming hole in advance at a predetermined position on the substrate 1, and then attaching the supporting shaft 8 and the supporting member 1.
0 may be molded integrally with the substrate 1 using a synthetic resin similar to these.

According to this proposal, since the substrate is made of a metal plate, the substrate can sufficiently withstand wear caused by the transfer of steel balls and can be used for a long period of time. Since it is fixed to the board, there is no need to attach a spindle and a support member during the assembly process, which simplifies the assembly process and improves its workability.

In addition, compared to conventional systems in which the support part for fixing the wire outer tube is formed by bending a part of the board, the board can be made into a nearly flat plate, eliminating the need for bending the board. This makes it easy to manufacture and has practical effects such as cost reduction.
