Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cleaning brush, and more particularly to a brush used for cleaning the walls, windows, sunroofs and the like of vehicles and buildings.

[Prior Art] As shown in FIGS. 7 to 8, a conventional cleaning brush has a brush head (a) fixedly provided at its tip and a brush serving as a cleaning agent container. It is composed of a handle (f).

Scraper (d) and sponge (e) as cleaning tools
Inserts them between the brush mounting head (a) and the brush retainer (c) and inserts a screw (c4) into the screw hole (c3) to attach them to the respective mounting portions (c1) and (c2). It is installed.

The cleaning agent spray pump (b2) is attached near the other end of the brush head (b) (the side connected to the brush handle (f)) so that the spray nozzle (b3) can be seen through the notch (b3). To be On the other hand, on the outer peripheral surface (f1) of the tip of the brush handle (f) (on the side connected to the brush head (b)), unevenness (both members (b),
(It becomes a pull-out resistance of (f)) is formed, and after applying an adhesive to this surface, both members (b) and (f) are fixed to each other by fitting into the brush head (b). Be connected.

Further, a lid (not shown) is provided at the other end of the brush handle (f) (on the side not connected to the brush head (b)), and the lid must be removed to replace or replenish the cleaning agent. Done by.

[Problems to be Solved by the Invention] When the cleaning brush is used for cleaning a window (generally a vertical surface except for special ones), the cleaning person first positions the cleaning brush in parallel with the surface to be cleaned. After spraying the cleaning agent on the window,
The cleaning brush is pressed against the surface to be cleaned while maintaining a certain angle (hereinafter referred to as the corner) to perform the cleaning operation. On the other hand, when cleaning an object to be cleaned such as a sunroof or a light harvester (generally a part of the ceiling, it is a horizontal surface or a curved surface that extends in the horizontal direction) Since it is not possible to position it in the upper part of the body, it is necessary to bend the upper part of the body and bend the wrist to maintain the corner.

Further, since the scraper (d) and the sponge (e) are mounted by the one brush pressing member (c), if one of them is replaced, the other one is also dropped at the same time. At that time, since the scraper (d) is made of a slightly hardened rubber, for example, by forming a groove corresponding to the shape of the scraper (d) in the mounting portion (c1), the mounting is not so difficult. Although not felt, since the sponge (e) is soft and easily deformed, some technique is required to set the brush pressing member (c) while holding the sponge (e) in the mounting portion (c2).

Further, since the cleaning agent storage tank is fixed to the brush,
It is necessary to replace or replenish the cleaning agent at the cleaning agent storage location or to prepare a preliminary cleaning agent at the work location. When the worker and the surface to be cleaned are separated from each other, a scaffold or the like should be provided to allow the worker to approach the surface to be cleaned.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and enables cleaning work to be performed in a comfortable posture, replacement of cleaning members such as scrapers and sponges, and replacement / replenishment of cleaning agents. The purpose is to make it possible for anyone to easily perform, and to expand the washable range as much as possible without moving the work place.

You may make it the structure equipped with the upper end surface.

The configuration of the present invention will be described in detail based on an embodiment.

As shown in FIG. 1, the brush of the present invention is broadly divided into a brush head 10, a brush handle 30, and a connecting member 20 connecting both of them. Incidentally, FIG. 2 is an exploded perspective view of FIG.

Scraper mounting parts on both sides of the brush head 10 are structured so that the scraper 2 and the sponge 3 can be easily replaced.
11 and the sponge sandwiching member mounting portion 12 are arranged so that the brush head 10 can be rotated at its lower portion via a rotating mechanism 23 about an axis orthogonal to the axis of the brush handle 30 at the brush head side end of the connecting member 20. Brackets 13 are provided respectively.

The state in which the scraper 2 and the sponge 3 are mounted on the brush head 10 is shown in FIG. 3, and the scraper 2 is slid at its end into a longitudinal groove formed in the scraper mounting portion 11 whose shape is traced. By inserting, the sponge 3 is formed at the tip of the sponge sandwiching member mounting portion 12 while sandwiching the end of the sponge sandwiching member 122 (see FIG. 4) with the sponge sandwiching member mounting guide groove 1221 of the member as a guide. It is mounted by inserting the member 122 while sliding on the boss 12111. Here, the member 122 is provided with locking claws 123 that alternately face each other on the inner surface in the vicinity of the released long side of the opposite surface thereof, and the member 122 can be mounted on the member mounting portion 12. Inevitably, the nail 123 bites into the sponge 3, and the sponge 3 moves to the brush head 10.
Firmly attached to. On the contrary, due to such a structure, the scraper 2 and the sponge 3 can be easily replaced by pulling out the scraper 3 and the sponge sandwiching member 122 from the respective mounting portions 11 and 12 in the longitudinal direction.
Although a combination of a scraper and a sponge is illustrated as the cleaning member, they may be used alone or a bristles of brushes or the like may be used as one of them depending on the purpose of cleaning.

Next, the rotating mechanism will be described (see FIGS. 5A and 5B).

The rotating mechanism 23 includes the interlocking unit 232, the spring 233, the pushing member 234, the rod 235, and the bracket 13 of the brush head 10.
U-shaped connecting piece 131 and hollow cylindrical connecting member 2 formed on
The bracket plate 2311 is formed on the bracket support 231 of 0. Here, each member is a connecting member
1 in the order of pushing member 234 → spring 233 → bracket plate 2311 → U-shaped connecting piece 131 → interlocking unit 232 (see FIG. 2) symmetrically from the outer side to the inner side about the axis of 20. The pushing members 234 are arranged one by one.
And the interlocking unit 232 are the axial rods 2341, 2321 that are fitted in the ring-shaped notches 2351 of the axial rod 235 so that the ring-shaped projections 2322 of the interlocking unit 232 come into close contact with each other.
5 are integrally attached so as to move in the axial direction thereof (here, both members are abutted by the abutting portion 2342 of the pushing member 234). In addition, the inner peripheral surfaces of the bracket plate 2311 and the U-shaped connecting piece 131 (the inner tooth forming portion 231
2 and 132) are engraved with tooth profiles of the same diameter, while
On the outer side of the interlocking unit 232, a gear (called an outer tooth forming portion 2323) formed coaxially and integrally therewith and having the same diameter as the inner teeth is formed. A state in which both interlocking units 232 are maximally separated from each other by the extension force of the spring 233 (see FIG. 5 (a)), that is, this is a normal state. Brush head 10
Is restricted in its rotation. On the other hand, a force is applied to the pushing member 234 in the direction in which they approach each other with a finger (the direction of the arrow in FIG. 5B) (the spring 233 is compressed).
And the internal teeth of the bracket plate 2311 and the interlocking unit 23
Since the gear of 2 is disengaged, brush head 1
Rotation of 0 is possible (the rotation angle can be up to 180 degrees) (see FIG. 5 (b)).

Further, a connection mode between the connection member 20 and the brush handle 30 will be described (see FIGS. 6 (a) and 6 (b)).

After a brush handle mounting member 31 having an internal thread formed on an inner surface thereof (referred to as a female screw forming portion 313) is screwed onto an end portion (male screw forming portion 311) of the brush handle 30, the mounting member 31 is connected to the connecting member 31.
While inserting the boss 315 having a width slightly narrower than the width of the L-shaped notch 22 of 20 into the notch 22 until the tip of the boss comes into contact with the contact surface (p) of the notch 22 (see FIG. )reference),
Then, by rotating the handle 30 in the clockwise direction, the boss 315 is locked in the inner part of the notch 22 (see FIG. 6 (b)) to complete the connection. Here, since the boss 315 goes over the protrusion 221 formed in the notch 22 in its rotational movement, the protrusion 221 acts as a resistance against the reverse rotation of the handle 30. become. (The unexplained reference numeral 312 is a fixing grip, and 314 is an unevenness forming portion for smoothly transmitting the force to the mounting member 31 when the mounting member 31 is screwed into or removed from the handle 30. ).

In this embodiment, the connecting member 20 and the brush handle 30 are connected via the mounting member 31, but this is a mode in which the handle 30 is used as a container for the cleaning agent and a spray pump is attached to the upper end portion thereof. (The notch 21 shown in FIG. 1 and FIG. 2 is for the spray nozzle of the pump and for spraying work (pressing with a finger)), the pump is detachably attached to the brush handle 30. Attaching it (the cleaning agent can be replaced / supplemented by unscrewing the attachment member 31 and the handle 30), and the pump can be attached to the brush handle 30 from the connecting member 20. It is designed to be removable (it can be accompanied with the brush handle 30 with the pump preliminarily filled with the cleaning agent at the cleaning work place), and as in the prior art, the handle ( When attaching a lid to the lower end of f) to replace and replenish the cleaning agent The pump to the handle (f)
