Description

[Detailed explanation of the idea] Industrial applications This idea concerns screen doors.

Prior Art A device described in Japanese Utility Model Application Publication No. 54-89041 is known as a conventional screen door with a decorative material placed adjacent to the screen material to improve the appearance and increase the strength. .

In this invention, a groove for attaching a netting material and a groove for attaching a decorative material are formed in the frame, and a locking piece is formed in the groove for attaching the decorative material to protrude into the groove from the tip of the side wall. A notch is provided at the end of the decorative material, and the four circumferential ends are fitted into the grooves for attaching the decorative material of each square frame, and the locking pieces are engaged with the notches of the decorative material. It must be stopped and assembled.

Problems to be solved by this invention The problem with the above-mentioned screen door is that there is inevitably a clearance between the locking piece of the groove for attaching the decorative material and the notch, and there is a gap between the frame and the decorative material. There were cases where the fittings became loose and the luxurious feel of the fittings was lost.

In addition, when the tension of the net material is applied to the stile, the net material becomes a string and acts as a force that bends the stile into an arched shape. If there is a clearance between them, the stile will deform and will not be able to be properly installed on the upper and lower screen door rails, making smooth opening and closing impossible.

Further, dirt tends to accumulate in the groove for attaching the decorative material.

The purpose of the screen door according to this invention is to solve the above problems, and to provide a screen door that does not rattle, does not impair the sense of luxury, does not bend under the tension of the screen material, and does not accumulate dust. .

Means for Solving the Problems The screen door according to this invention is constructed by assembling upper and lower horizontal stiles and left and right stiles in a rectangular shape, and stretching a net material on the inner circumferential side of each of the stiles assembled in a rectangular shape. A continuous welding protrusion is provided in the longitudinal direction, and the ends of decorative materials stacked on the front and back are placed in contact with the welding protrusions between the frames, and the contact points between the decorative materials, the decorative material, and each frame are It is assembled by welding the contact point with the welding protrusion.

Embodiment Hereinafter, this invention will be explained in detail based on an embodiment shown in the drawings.

In the figure, numerals 1 and 1 are upper and lower horizontal stiles, which are assembled into a rectangular shape with left and right stiles 2, 2. The upper and lower horizontal frames 1, 1 each have a hollow portion 6 having a substantially rectangular cross section formed by an inner circumferential side wall 3, an outer circumferential side wall 4, and indoor/outside walls 5, 5. A projecting piece 7 that is flush with the indoor side wall 5 of the hollow part 6 and has a hook-shaped tip bent toward the outdoor side is provided between the projecting piece 7 and the inner circumferential side wall 3. A net material attachment groove 8 is opened. Also, on the inner circumferential side of the square frames 1 and 2 of this projecting piece 7, there is a welded projection 9 whose tip has a circular cross section.
are continuously protruded in the longitudinal direction. In the case of the upper and lower side frames 1, 1, a welding protrusion 9 is provided to protrude toward the outside side in the width direction.

Although not shown in the left and right frames 2, 2, a net material attachment groove 8 that opens toward the outdoor side is formed, and a welding protrusion 9 is provided to protrude toward the indoor side in the width direction.

In the figure, reference numeral 10 denotes a decorative material, in which a plurality of front decoration materials 10a disposed on the indoor side and a plurality of back decoration materials 10b disposed on the outdoor side are overlapped in a grid pattern. The surface decoration material 10a is arranged vertically,
The upper and lower ends are in contact with the interior side surfaces of the welding protrusions 9, 9 of the upper and lower side frames 1, 1, the back decoration material 10b is arranged horizontally, and the left and right ends are in contact with the welding protrusions of the left and right frames 2, 2. It is in contact with the outdoor side surfaces of the parts 9,9.

The contact points between the front and back decorative materials 10a, 10b, the ends of the decorative materials 10a, 10b, and each frame 1,
The contact point with the welding protrusion 9 of No. 2 is welded and fixed by spot welding. Welding protrusion 9 of horizontal stile 1 and vertical stile 2
The contact point with the welding protrusion 9 is also fixed by welding.

After being welded and fixed as described above, the mesh retainer 11 is fitted into the mesh material mounting groove 8 of each frame 1, 2 which has been alumite treated or coated with a coating material, and the four peripheral ends of the mesh material 12 are attached to each frame 1. , 2, and a net material 12 is stretched.

The decorative material 10 disposed within each frame 1, 2 is integrated by welding so that there is no rattling, and the frames 1, 2 are reinforced to prevent deformation of the frames 1, 2 due to the tension of the mesh material 12.

This invention has the above-mentioned configuration, but the other thing shown in FIG.
is provided so as to protrude flush with the indoor wall 4, and its tip is formed to have a substantially semicircular cross section. In this case, the front decoration material 10a is arranged horizontally and the back decoration material 10b is vertically arranged, and the upper and lower ends of the back decoration material 10b are placed outside the welding protrusions 9, 9 of the upper and lower horizontal frames 1, 1. It may also touch the side.

In addition, as shown in FIG. 4, front and back decorative materials 10a, 1
0b may be made diagonally and intersect instead of in the form of a grid. At this time, the front and back decorative materials 10a and 10b are bent at their ends in directions away from each other, and brought into contact with the front and back surfaces of the protrusions 9 of the frames 1 and 2 to be welded.

FIG. 5 shows a case where the present invention is applied to a folding screen door.

Effects of the invention The screen door according to this invention has the above-mentioned configuration, and each stile is assembled in a rectangular shape, with continuous welded protrusions protruding in the longitudinal direction on the inner circumference side, and decorations overlapped on the front and back sides. It is assembled by placing the end of the material in contact with the welding protrusion between the frames, and by welding the contact points between the decorative materials and the contact points between the decorative material and the welding protrusion of each stile.

Therefore, the frame and the decorative material are integrated by welding and fixing, and the screen door does not rattle when opened or closed, and the luxurious feel is not impaired.

Furthermore, since the decorative material is placed between the frames and fixed by welding, it serves as reinforcement, and the frames do not deform even under the tension of the screen door, so there is no problem in opening and closing the screen door.

Furthermore, since there are no grooves for attaching decorative materials, dirt does not accumulate and it is sanitary.

Decorative materials can be used in place of latticework, and if you attach a lock to the screen door, the screen door will serve as a security feature even if the shoji screen is opened.
