JP2015209754A - Window screen re-covering ruler - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the problem of so far requiring a skilled technology for coping with a window screen of various sizes, similarly to a new product in its case, though pushing in and stretching a net so as not to loosen and bend in a groove of a window screen body by pushing-in rubber, by using a window screen roller in re-covering work of the window screen.SOLUTION: A skilled technology such as re-covering without bending and straining, becomes unnecessary from the present invention, by tracing by a fluorescent pen, after being confirmed-adjusted, since a strain and a flow of a mesh of a net becomes easily confirmable, by providing a part of a square hole in a ruler.

Description

  The present invention relates to a screen door replacement work.

  The screen door was reworked by using a screen roller and pressing the rubber into the screen door groove so that it did not sag and bent, and pushed in.

  In the present invention, when the screen door is replaced, the net does not bend like a new product, and there is no distortion, and it is necessary to have skill to adapt them to various sizes. The present invention is intended to be replaced without the need for such a technique.

  A long hole is provided symmetrically with respect to the center of the rectangular base.

  Conventionally, the screen doors that have been required to be skillful can be replaced by the present invention, and can be replaced according to various sizes without bending and without being bent.

Perspective view of the present invention Side view of the present invention FIG. 3 is a state diagram in which the ruler body (1) is placed on the net (7) and it is confirmed that the mesh seen from the square hole (2) is not bent. The state figure which is pulling the highlighter pen (8) while imagining the place to push in the mesh seen from the square hole (2) with the rubber (9). Remove the ruler body (1), place a net on the screen door body (12), place the highlighter mark (10) on the left side (13) of the rubber groove, and push it in with the screen roller (11). The state figure which is pushed in. FIG. 6 is a state diagram in which the work of pushing in the push-in rubber (9) on the left (13) of the rubber groove vertical part in FIG. 5 is completed and the work of the rubber groove upper part (14) is performed in the same procedure as in FIGS. The pushing operation of the rubber groove upper part (14) in FIG. 6 is completed, and the net (7) around the remaining rubber groove vertical part right (15) and the rubber groove lower part (16) is directed outward of the screen door body (12). The state figure which is pushing in pushing rubber (9) with a screen door roller (11), pulling. The completed figure after cutting off the surplus part of a net | network (7) and the surplus part of an indentation rubber | gum (9) with a cutter knife (17).

Embodiments of the present invention will be described below.
(A) As shown in FIG. 1, the ruler body (1) is provided with a square hole (2) having a thickness of about 5 mm to 20 mm, for example.
(B) As shown in FIG. 2, anti-slip (3) is provided on the back of both side portions.
(C) For screen door rubber (9) with a diameter of about 2mm to 8mm and a spacing of 0.2mm to 1mm, matched to the screen door rubber (9) sold on both sides or one side of the ruler body (1) A measuring hole (4) is provided. When it is desired to replace the small rubber (4) due to deterioration of the push-in rubber (9) or the like, the diameter can be easily measured by passing the existing push-in rubber (9) through the small hole (4).
(D) The scale (5) is provided with scales (6) at intervals of 1 mm or more at the upper bottom (18) and the lower bottom (19). At this time, it is desirable to provide a scale (6) in the center of the ruler body (1).
The present invention has the above structure.

The usage method of this invention is demonstrated along FIGS.
As shown in FIG. 3, the position of the mesh is adjusted and installed in the square hole (2) portion of the ruler body (1) so that the mesh of the mesh (7) is not distorted straight.
As shown in FIG. 4, the square pen (2) of the ruler body (1) is traced with the fluorescent pen (8) to confirm that the fluorescent pen (8) is attached to the mesh.
As shown in FIG. 5, the ruler main body (1) is removed and the push-in rubber (9) of the screen door main body (12) is pushed in, and the highlighter mark (10) is superimposed on the left side (13) of the rubber groove, and the push-in rubber (9) is put on. Push in with screen door roller (11).
As shown in FIG. 6, the rubber groove upper portion (14) is subjected to the steps shown in FIGS. 3, 4 and 5 in the same manner, and is pushed by the screen roller (11) and pushed into the rubber (9).
As shown in FIG. 7, the rubber groove vertical part left (13) and the rubber groove upper part (14) one side, a total of two sides, the rubber (9) was pushed into the L-shape, so the remaining two sides and the L-shaped part Push in rubber (9) while pulling lightly outward of the screen door body (12).
The completed drawing which cut off the surplus pushing rubber (9) and cut off the surplus net (7) with a cutter knife as shown in FIG.

1 ruler body, 2 square holes, 3 slip stoppers, 4 small holes, 5 scales, 6 scales, 7 meshes, 8 light pens, 9 push-in rubber, 10 highlighter marks, 11 screen door rollers, 12 screen door bodies, 13 rubber groove vertical parts Left, 14 rubber groove upper part, 15 rubber groove vertical part right, 16 rubber groove lower part, 17 cutter knife, 18 body upper bottom, 19 body lower bottom
