Description

[Detailed Description of the Invention] The present invention relates to an electric wiping device that has a brush, mop, etc. that performs wiping action using the electric power of a motor, and is suitable for use in wiping, washing, polishing, etc.

Conventionally, so-called electric wipers used for wiping, cleaning, polishing, etc. the exterior surfaces of bathrooms, automobiles, etc. have one end of a tubular handle connected to one side of the body of the wiper, which performs the wiping operation using electric power. Most of them have a structure in which the cord is introduced from the other end of the handle.During manufacturing, the handle is equipped with a cord inside and a switch pre-attached to the cord is inserted through the handle. Since the assembly process involves fitting the switch button into the provided switch mounting hole from the inside to expose the switch button to the outside, and fixing the cord with a fixture at the other end of the handle, the length of the handle may be longer. ,
This has disadvantages in that the assembly work is difficult and the wiper has to be the size of a handgrip at most, which limits the effectiveness of the wiper.

The present invention was made to eliminate the drawbacks of conventional products such as Narukami, to provide an electric wiper that allows the length of the handle to be lengthened according to the use of the wiper, and that is easy to assemble. It is something.

Next, one embodiment of the present invention will be described in detail with reference to the drawings.

In Figures 1 to 3, reference numeral 1 denotes a head that is equipped with a drive unit mainly consisting of a motor, and has an outer shape in which the upper part of a conical body is twisted laterally and crowned diagonally. ,
A rotary brush 2 serving as a wiping tool is attached to the bottom, and a joint 4 having an annular cap 3 is attached to the top.
are connected, and the head 1 is rotatable with respect to the joint part 4, thus forming a wiping tool body 5.

Reference numeral 6 denotes a tubular handle whose one end is connected to the wiping tool body 5 by the annular cap 3 of the wiping tool body 5, and a cord 8 having an insertion plug 7 is introduced from the other end of the handle 6.

A switch mounting hole 9 is provided through the handle 6, and a fixed wall 10 is provided on the inner wall of the other end.

Reference numeral 11 designates a support base made of polyolefin synthetic resin as shown in FIG. 3, and has a switch mounting portion 12 at one end.
is provided, and a switch 14 is attached using the screw hole 13, and the switch 14 is attached to the switch mounting part 1.
The switch button is pivotally attached to the grip lever 6 using a screw hole 15 protruding from the upper surface of the switch 2 so that the switch button protrudes from the switch mounting hole 9 with a screw 16.

17 is a waterproof cap.

A block-shaped cord fixing device 18 is provided at the other end of the support base 11, and a male screw 19 is provided protruding from the tip thereof, and a cord insertion hole 20 is provided in the center, and an extension portion of the cord 8 is provided. is arranged inside the handle 6.

The cord fixing tool 1B is inserted through an elastic packing 21, its male screw 19 passes through the mounting hole 22 of the fixing wall 10, and is attached to the cap nut 2 from the outside of the other end of the gripping lever 6 via the elastic packing 23.
4 is screwed on.

Further, the center portion of the support stand 11 is bent into a V-shape, and the bend line portion forms a hinge structure 25, making it freely expandable and retractable.

In addition, as a means for making the support stand expandable and retractable, for example, as shown in FIG. A sliding groove (not shown) provided on the circumferential surface of a sliding protrusion 29 provided at the tip of the other plate 27 may be inserted into both sides of the elongated hole 28 to allow free sliding.

30 is an O-ring fitted into the annular groove 31.

To assemble an electric wiper configured like Narukami,
The switch 14 is attached to the switch mounting part 12 of the support base 11, the cord 8 is inserted into the cord fixing tool 18, and the grip rod 6 is arranged along the support base 11 in FIG.
from the left end, pass the plug 7 and part of the cord 8 through the mounting hole 22 of the fixed wall 10 at the right end, and tighten the cap nut 24.
The cord fixture 18 is screwed and fixed to the fixed wall 10 at.

Next, the switch 14 is attached to the switch mounting hole 9, and at that time, the hinge structure 25 is used as appropriate to support the support base 1.
After connecting the terminal 32 of the cord 8 to the terminal (not shown) of the annular cap 3, the grip rod 6 thus formed is attached to the inner circumferential wall of the annular cap 3 (also not shown). The annular groove 31 may be fitted into a fitting groove provided in the fitting groove.

In the present invention, the switch and the cord fixing device are attached to the support stand, so even if the gripping rod is long, it is easy to assemble it to the gripping rod, and it is easy to assemble it to the gripping rod as appropriate depending on the use of the wiper. The grip size can be changed to improve the function of the wiper.

Further, since the support base is extendable and retractable, when attaching the switch and the cord fixing device to the gripping rod, dimensional errors in the parts themselves and compression allowance of the elastic backing are sufficiently absorbed, and positioning is easy.
