Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a screen door, and more specifically, a technology that avoids replacing the entire screen door in case of partial damage, increases strength, and improves workability. Regarding.

[Background technology] Conventional screen doors are made by combining wire rods, but they can be easily torn by sharp knives or benches, creating security problems. I had to replace it.

In addition, there are screens that are made by forming holes in a single flat panel, but these are easily deformed or damaged when subjected to external forces, and some parts are damaged. If it got dirty or dirty, I had to replace it all. To solve this problem, the Utility Model No. 47 shown in Fig. 5 is used.
As in Publication No. 3542, a unit member 2 having a small hole 1'
It is also possible to construct a screen door by connecting the unit members 2' in the vertical direction, but the shape is different in that the top and bottom and the front and back are reversed, and the top and bottom and front and back are specified, and the screen door made by connecting these unit members 2' in the top and bottom and front and back is different. There was a problem that it could not be installed by flipping it over, and although it was constructed using unitary materials, it was difficult to install. [Object of the invention] The present invention has been made in view of these problems,
The purpose of this is to use unit materials to avoid having to replace the whole thing in the event of partial damage, and to increase the strength of the screen door by connecting the unit materials in series. Another object of the present invention is to provide a screen door that can be easily installed by eliminating the front and back sides.

[Disclosure of the Invention] The present invention provides an elongated unit surface material having a large number of small holes in a wavy shape in which the peaks and valleys are continuous on the side pieces, and in the longitudinal direction along the peaks and valleys of the wavy shape. A downwardly inclined part is formed at one end in the right angle direction, a locking part is formed on the upper surface of this downwardly inclined part, and an upwardly sloped part whose slope is roughly similar to the slope of the downwardly inclined part is formed at the other end. A locked part is provided on the lower surface of the part, and a plurality of unit panels are connected by the locked part and the locked part. This has been achieved.

The present invention will be explained in detail below with reference to Examples. In the figure, reference numeral 2 denotes an elongated unit plate formed by extrusion molding of metal or synthetic resin, and is provided with a large number of small holes 1 for ventilation. This unit plate has a wavy cross section, and the embodiment shown in Fig. 2 shows an example in which it is bent into a trapezoidal wave shape.
It may also have a wavy shape with a different shape. In the figure, 5 is a mountain forming a wavy shape, 6 is a valley, and 7 is a side piece, and the crest 5 and the valley 6 are connected by an inclined side piece 7, and the wavy shape of the crest 5 of the unit surface village 2 is Side pieces 7 are located at one end and the other end in a direction perpendicular to the longitudinal direction of the valley 6. Here, the upper side piece 7 and the lower side piece 7 protrude in opposite directions. One side piece 7 is sloped downward, and a locking part 3 is formed on the upper surface of this downward slope. The side piece 7 at the other end is an upwardly sloped part with a slope substantially equal to the slope of the downwardly sloped part, and a locked part 4 is provided on the lower surface of this upwardly sloped part. Locked part 4
A plurality of unit panels 2 are connected by locking them. A screen door is formed by attaching the cage 8 to the outer periphery of a panel made by connecting a plurality of unit panels 2 as described above. In the embodiment shown in FIG. 2, the locking part 3 has a convex shape with the protruding base narrower than the protruding part, and the locked part 4 has a concave groove shape with the opening □ narrower than the inside. . Further, in the embodiment shown in FIG. 4, a tapping hole 9 is provided in one of the locking part 3 and the locked part 4.
The face material is attached to the paddle 8 using tapping screws 101. Note that the unit panel material 2 may be elongated in the vertical direction as shown in FIG. 3, or may be elongated in the horizontal direction as shown in FIG. [Effects of the Invention] In short, the present invention provides a wavy shape in which an elongated unit surface village having a large number of small holes is continuous on the side pieces, and a longitudinal direction along the crests and troughs of the wavy shape. A downward slope is formed at one end in the perpendicular direction, a locking part is formed on the upper surface of the downward slope, and an upward slope is formed at the other end with a slope substantially equal to the slope of the downward slope, A locking part is provided on the lower surface of this upward slope, and a plurality of unit panels are connected by the locking part and the locked part, so there is no chance that some of the panels will be damaged or dirty. By taking advantage of the advantage of using a unit material, which means that you only need to replace some of the unit materials and not all of them, it is possible to create a sharp knife by combining wire rods with silk. It is hard to tear on benches or benches, improving the crime prevention effect, and its wavy shape makes it strong and resistant to deformation or damage even when subjected to external force.

Moreover, since the locked part on the lower surface of the up-sloping part is locked to the locking part on the upper surface of the down-sloping part, the connection point of the unit plate with the locked part locked to the locking part can be connected to the up-sloping part. In a screen door that can be hidden on the bottom surface and in which unit panels are connected continuously, the front and back shapes can be made equal, and the upside-down shape can also be made to be the same, and as a result,
There is no need to specify the top and bottom, as well as the front and back, of the screen door that connects the unit panels in a continuous manner, which has the advantage of improving ease of construction.
