Published practical application No. 3-18219 Published practical application No. 56-96118 JP 2010-77641 A

Conventionally, a broom or the like is used to remove dust on the line. In that case, the user moves the broom in the direction in which the line extends to brush off the dust, while turning the user's body sideways parallel to the line. I had to move, which was a hassle.
In addition, since the line brush of the above patent document only rotates in the same direction on the line, there are cases where dust is left behind. Furthermore, since the brush is pressed against the line to sweep, it tends to be a large or heavy cleaning tool. For this reason, it required space for storage, and was heavy and difficult to move.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a cleaning tool that is lightweight and compact and that can sweep out dust on the line.

(1) The line cleaning tool of the present invention comprises a frame, a rotating shaft rotatably provided on the frame, a roll brush rotating with the rotating shaft to clean dust on the line, and a roll brush provided on the frame. and includes a guide member having an inclination for elastically deforming the tufts of the roll brush inward toward the bottom, and a tire connected to the rotating shaft, the bristle tufts being guided inward by the guide member. is characterized by sweeping out the dust on the line by recovering due to its elasticity.

(2) Such a line cleaning implement preferably has a handle arm on said frame.

(3) Further, it is preferable that the tire and the roll brush are provided on both sides of the axle.

[1. Outline]
<First Embodiment>
The outline of the line cleaning tool will be described with reference to FIG.
The line cleaning tool 1 shown in FIG. 1 includes a frame 2, a rotating shaft 3 rotatably provided on the frame 2, and a line 1a (see FIG. 3) that rotates together with the rotating shaft 3 to remove dust (see FIG. 3) on the line 1a (see FIG. 3). a roll brush 4 to be cleaned, a guide member 5 (see FIG. 2) provided on the frame 2 and having an inclination that elastically deforms the bristles 3a of the roll brush 4 inward toward the bottom (see FIG. 2), and a rotating shaft 3. and a tire 6 connected to the The tufts elastically guided inwardly by the guide member 5 are restored, thereby sweeping out dust on the line 1a.

The line cleaning tool 1 also has a frame 2 with a handle arm 2a.

Further, the line cleaning tool 1 is provided with tires 6 and roll brushes 4 on both sides of the rotating shaft 3, respectively.

[2. Each configuration]
(Frame 2)
The frame 2 of this embodiment has a shape that serves to support the rotating shaft 3 and the guide member 5, respectively. In this embodiment, a bearing for supporting the rotary shaft 3 is provided approximately at the center of the lower member 2b of the frame 2, and a guide member 5 (see FIG. 2) having the same bearing is provided inside.

(rotating shaft 3, tire 6)
The rotary shaft 3 is rotatably provided on the frame 2 and is a member that connects the roll brush 4 and the tire 6 members. The rotating shaft 3 of the present embodiment mainly uses the tire 6 as a power source, and when the tire 6 rotates, the rotating shaft 3 and the roll brush 4 rotate.

(roll brush 4)
The roll brush 4 consists of a base portion 1b having a plurality of bristles 3a.

(Base portion 1b)
The base portion 1b is a columnar member connected to the rotating shaft 3, and hairs 3a grow from the side end surface 1c.

(hair 3a)
The bristles 3a have elasticity and are curved outward toward the tips of the bristles.
(hair material)
For example, a material having elasticity such as polypropylene or plastic is used. In addition, it may be made of a known elastic material.

(Guiding member 5)
As shown in FIG. 2a, the guide member 5 has a guide surface 5a for guiding the bristles 3a inwards. The edge portion of the guide surface 5a protrudes inward as it goes downward. For example, as shown in FIG. 2b, the edges of the guide member 5 are arranged in the order of the AO line section (see FIG. 2c), the BO line section (see FIG. 2d), and the CO line section (see FIG. 2e). The amount of inward protrusion of the part gradually increases. As shown in the CO line cross section (see FIG. 2e), the edge portion of the guide member 5 protrudes inward to the maximum at this cross section position. This maximum amount of projection is such that the vicinity of the tip of the bristles 3a reaches a position approximately half the width of the line (see S3 in FIG. 3).

(line 1a)
In the case of tennis, the line 1a has a width of 25 mm to 100 mm, is made of plastic, and is fixed to the ground with nails in the clay court.

[3. how to use]
(how to use)
Next, with reference to FIG. 3, how the line cleaning tool 1 works will be explained. FIG. 3 is a schematic view corresponding to the guide member of FIG. 2b and showing the positions S1-S5. FIG. 3b is a schematic diagram showing the cross-sectional shape and bristles of the guide member 5 at the position shown in FIG. 3a. The roll brush 4 rotates in directions S1 to S5.

(Step S1)
As shown in Figures 3a and 3b, the bristles 3a at position S1 are curved outwards. Therefore, it never touches the line.

(Step S2)
From this position, the inward protrusion amount of the edge portion of the guide member 5 increases, and along with this, the bristles 3a also begin to face inward.

(Step S3)
The vicinity of the tip of the bristles 3a comes into contact with the line 1a and can catch dust on the line. At this position, the edge portion of the guide member 5 protrudes inward to the maximum.

(Step S4)
Since the protruding amount of the edge portion of the guide member 5 is reduced, the bristles 3a return to the outside due to the elastic force. This allows dust to be swept out.

(Step S5)
Since the amount of projection of the guide member 5 disappears, the bristles 3a also return to the outwardly curved state.

[4. Other embodiments]
Another embodiment of the frame 2 is described in FIG. Since the frame shown in the figure has many parts in common with the above-described frame 2, explanations of the same parts are omitted and different parts are explained.
The frame 7 shown in FIG. 4 has an inverted Y shape. Both ends of the rotating shaft 3 are rotatably supported by the bifurcated portions 7a, 7a of an inverted Y shape.

[5. summary]
(1) The line cleaning tool 1 of the present invention includes a frame 2, a rotating shaft 3 rotatably provided on the frame, a roll brush 4 that rotates together with the rotating shaft 3 to clean dust on the line 1a, The guide member 5 is provided on the frame 2 and has a slope that elastically deforms the bristles 3a of the roll brush 4 toward the bottom, and a tire 6 connected to the rotating shaft 3. The bristles 3a guided inwardly by are restored by their elasticity, thereby sweeping out dust on the line 1a.
Instead of pressing the bristles against the ground to sweep them out as in the conventional method, the bristles elastically deformed inside and the vicinity of the tips of the bristles are arranged on the line, and the bristles 3a are elastically deformed to restore the line 1a to the outside. You can sweep out the dust from the inside to the outside. Therefore, the weight and size required for pressing can be reduced, and the weight and size can be reduced.

(2) Such a line cleaning tool 1 has a handle arm on the frame 2 and is easy to use.

(3) Further, since the tire and the roll brush are provided on both sides of the rotating shaft, the left and right bristles are curved inward, and each bristles elastically restores outward on the line. Therefore, almost the same sweeping force acts on the left and right sides, so that the cleaning can be performed stably along the line and the cleaning can be easily performed.
