Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a floor suction tool for a vacuum cleaner, and particularly to a brush body energizing mechanism.

Conventional technology In the past, in this type of floor suction tool, the brush body was biased in one direction by a spring interposed between the brush body and the lower member (
Utility Model Publication No. 48-9537, Utility Model Number 49-32450
-! Public bulletin).

Problems to be Solved by the Invention However, with this configuration, the spring must be held when the brush body is assembled, which is very troublesome.

That is, since the floor suction device was assembled with the upper member facing down and the lower member covered, the spring would fall if left as is.

It is also conceivable to form a protrusion for holding the spring on the lower member, but since the lower member is made of metal, it is difficult to make it, and the height cannot be made very high.

Therefore, the spring retention function cannot be expected very much,
There were problems such as shifting.

The present invention eliminates these conventional drawbacks and simplifies assembly.

Means for Solving the Problems In order to solve these conventional problems, the present invention includes an upper member having a pipe connected to a vacuum cleaner, a dust suction port, and a dust suction port extending in both directions from the dust suction port as a base point. A suction device main body is constituted by a lower member having a ventilation recess, and a brush body that protrudes and retracts from the lower member by the operation of a cam body and a biasing mechanism that biases this brush body in one direction are provided in the suction device main body. established,
The biasing mechanism is composed of a rotatable lever having one end connected to the brush body, and a spring attached to a spring receiver of the upper member and connected to the other end of the lever.

Function: According to such a configuration, a biasing mechanism including a spring can be incorporated using the upper member as a base.

In addition, the lever mechanism allows the brush body to operate reliably.

Example Examples thereof will be described below with reference to the accompanying drawings.

In Figures 1 to 4, the main body 1 of the suction device includes an upper member 3 made of synthetic resin on which a pipe 2 connected to the suction side of the vacuum cleaner is rotatably attached, a dust suction port 4 in the center, and a dust suction port 4 in the center. Mouth 4
The dust suction port 4 is connected to the pipe 2 of the upper member 3 via an intermediate duct 7.

Inside the suction tool main body 1 is a cam body 8;
A brush body 10 that moves in and out through the cutout groove 9 of the lower member 6 in conjunction with the lower member 6 is provided.

That is, as shown in FIGS. 2 and 4, the cam body 8 is an arcuate member 11.1 protruding from the upper member 3 and the intermediate duct 7.
The center portion thereof is pivotally supported by the brush body 2, and a cam body 13 having an inclined surface is formed symmetrically at the portions sandwiching the brush bodies 10 on both sides.

Therefore, if the cam body 8 is rotated in one direction, the cam portion 1
The brush body 10 protrudes along the inclined surface 3 as shown in FIG. 4, and retracts when rotated in the opposite direction.

Reference numeral 14 denotes a rib integrally protruding from the upper member 3 to hold the brush body 10, and 15 and 16 refer to pedals for reversing and rotating the cam body 8. When one is standing on the upper member 3, the other is a fallen tree.

Now, reference numeral 17 denotes an urging mechanism for urging the brush body 10 in the backward direction, and is provided on both sides of the brush body 10.

Further, in detail with reference to FIGS. 1, 5 and 6, 18 is a contact point A of the ventilation recess 5 formed in the lower member 6 with the soil surface of the bottom wall.
It is a lever that rotates using the fulcrum as a fulcrum.
It has a notch 19 that engages with the upper member 3, and the other end is connected to a compression coil type spring 21 held in a spring receiver 20 integrally projecting from the upper member 3.

Reference numeral 22 denotes guide ribs for holding the levers 18, and a plurality of these levers 18 are integrally protruded from the upper member 3 between them.

In the above configuration, when the brush body 10 protrudes by operating the cam body 8, the lever 18 rotates clockwise against the spring 21, as shown in FIG. , the lever 1 is moved by the spring 21.
8 is rotated counterclockwise to move the brush body 10 backward.

Further, during assembly, after setting the brush body 10 on the upper member 3, the spring 21 and lever 18 can be assembled, and then the lower member 6 can be connected so as to cover it.

Effects of the invention As described above, according to the invention, the brush body and the energizing mechanism can be assembled independently regardless of the lower member. Therefore, it is much easier to assemble than the conventional one, and the cost is lower than that. It is possible to promote the reduction in the cost of
Furthermore, the presence of the lever allows for smooth movement of the brush body, resulting in excellent effects.
