Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to line drawing for use in playgrounds, etc.

<Prior art> At a sports field, for example, lines for track and field races are constructed by putting so-called lime such as calcium hydroxide or calcium carbonate in a box-shaped member with wheels, and using brushes, stirring blades, etc. attached coaxially to the axle. As the wheels rotated, a small amount fell down through the hole in the bottom of the box-shaped member and was pulled. This lime is usually supplied in a bag, from which it is manually placed into the box-like member.

<Problems to be solved by the invention> Since lime is a white powder, it easily scatters when it is transferred from a bag to a box-shaped member, and there is a risk of staining the surrounding area, hands and clothes, or getting it in the eyes.
Workability was also poor. In addition, since these limes are hygroscopic, the lime left in the bag solidified into blocks, which had to be crushed before being placed in the box-shaped member.

<Means for solving the problem> In order to solve this problem, the present invention includes a pair of wheels fixed to an axle, which are fixed coaxially to the wheels, and discharge lime little by little as the axle rotates. A cart consisting of a lime discharge member, a box-shaped member that surrounds this member and has a lime introduction hole on the top surface and a discharge hole on the bottom surface, and a hand-push member, and a lime discharge device that is detachably fixed to the cart and has a lime discharge hole on the bottom surface. To provide a lime-containing cartridge consisting of a box having a window and a sliding member for freely opening and closing the window.

<Function> As mentioned above, the line drawing system of the present invention is composed of two parts: a cart and a cartridge. A lime discharging member fixed coaxially with the axle of the truck allows lime to be discharged little by little from the discharge hole as the axle rotates.

<Example> Hereinafter, the present invention will be explained with reference to the drawings.

The drawings show an embodiment of the present invention, with FIG. 1 being a perspective view and FIG. 2 being a sectional view.

The line drawing of this invention is trolley 1 and cartridge 2.
It consists of

The trolley 1 includes a hand push member 11, a box-shaped member 12 having a discharge hole B opened on the lower surface, an introduction hole A also opened on the upper surface, an axle 13 provided through the box-shaped member 12, and attached to both ends of the box-shaped member 12. A pair of wheels 14 , a rotating brush 15 that is fixed coaxially with the axle 13 and discharges lime little by little as the axle rotates, and a metal wire 16 that connects the box-shaped member 12 and the push member 11 , and the metal wire 16 . It consists of a fixed cartridge 2 fixing means 17. The rotating brush 15 is a lime discharge member for dropping lime little by little from the discharge hole B by the rotation of the axle 13, and instead of the rotating brush 15, spiral grooves are cut in opposite directions with the center as the boundary. A screw-shaped one or the like may also be used.

Further, the cartridge 2 includes a box 21 containing lime D (the lime D may be placed in an open bag) and having a discharge window C on the bottom surface, and a slide member 22 that closes the window C so as to be openable and closable. It consists of
The slide member 22 consists of a base plate 23 that allows a slide 24 to move in and out. The base plate 23 is provided with a window corresponding to the window C of the box 21.
By moving 4, this window can be opened or closed. Both the box 21 and the slide member 22 are made of cardboard or plastic, but it is preferable to use a moisture-proof material, and the two are integrated at a predetermined position using an adhesive or the like. The box 21 may be provided with a handle 25.

The present invention is as described above, but the lime D is supplied to the consumer while being sealed in the cartridge 2, and after being installed at a predetermined position on the trolley 1, the window C is opened by the slide member 22 and the box is removed. into the shaped member 12.

<Effects> As described above, according to the present invention, Lime D can be used for line drawing without getting the hands dirty while being placed in the cartridge, so it does not stain the surrounding area or get into the eyes. It is easy and simple, and the lime does not absorb moisture, so it can be used for all lines. The amount of lime used can also be controlled by adjusting the opening of the window using a sliding member.
