Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a screen door frame that is stretched around an insect screen that prevents the intrusion of insects and dust and does not impair ventilation between indoors and outdoors.

Conventionally, as this type of screen door frame, there is one in which two locking plates that can be joined are extended from the tip of a plate-like base to form a screen attachment part with a roughly Y-shaped cross section (Utility Model No. 51-1999) 76947).

This screen door frame can be used by bending it from the joint part and bending it into an L-shape, etc., other than keeping it parallel to the plate-like board and the screen attachment part, but when used in this way, Since the locking plates are bent in one direction, the open ends of the locking plates are forced to return to their original shape, making it difficult to securely hold the insect screen for a long period of time.

Furthermore, as shown in FIGS. 12A and 12B, the guide rail 31 is inserted into the upper root 30A or lower root 30B forming the metal frame 30 made of aluminum or the like so as to be able to move up and down, but the slide adjustment is difficult. It is difficult to adjust to a wide range of dimensions due to the limited size, and gaps may appear depending on the fittings or the installation location, making it impossible to achieve a sufficient insect repellent effect as an insect repellent net.

In addition, this type of insect-proof screen door is made by assembling frame materials, so
The cost of materials was high, and the screens were thick, making it difficult to take up storage space. The present invention includes two flat plate-shaped locking pieces, one of which extends continuously and integrally to the flat base on the tip of the flat base to be fixed to a mounting portion such as a window frame, and , the other one is integrally provided with a weakened portion on the base side, formed to be bendable, and similarly extended integrally, so that one locking piece has a weakened portion on one side and the other locking piece is approximately parallel to the other locking piece. The two locking pieces are closely attached to hold the peripheral edge of the insect screen, and one of these two locking pieces has a locking pin protruding from the other, and the insect screen is inserted through the locking piece and engaged with the engagement hole formed in the other side. It is characterized by being fixed in place, and can be installed as a screen door frame not only in a parallel position but also by being bent at any angle, and one of the two locking pieces has a weak part on its base side. Therefore, even if the screen door frame is installed at an arbitrary angle, the screen door frame can maintain the necessary rigidity without becoming partially weakened, and its engagement can be facilitated to simplify assembly work. The object is to be able to firmly connect the screen door frame and the insect screen for a long period of time. The structure of the present invention will be explained based on the embodiments shown in the attached drawings. 1 is a main body of a screen door frame which is fixed to the periphery of an insect screen 2 made by weaving warp and weft threads, and a release paper (not shown) is attached to the mounting surface side. ) Two flat plate-shaped locking pieces 6a and 6b are integrally formed at the tip of the flat base 4 made of a hard material having a pressure-sensitive adhesive layer 3 stuck thereon. The locking piece 6b extends continuously and integrally with the flat base 4, and the other locking piece 6b has a flexible weak portion 5 made of foamed material or the like on its base side in the longitudinal direction. The two locking pieces 6a and 6b form an open holding portion 6, which is bendable and extends integrally with the locking piece 6a.

Further, a locking pin 7a having a bulging tip is provided on the inner surface side of the locking piece 6b having the weakened portion 5, and the front end of the locking pin 7a is inserted into the opposing locking piece 6a. An engaging hole 7b is formed to hold the holding portion 6 between the two locking pieces 6a and 6b.
After inserting the peripheral edge of the insect screen 2 into the
B is bent by the weak portion 5 so that it is parallel to the locking piece 6a on the saw side and tightly clamped, and the locking pin 7a protruding from the locking piece 6b is secured against insects. The tip of the peripheral edge of the net 2 is inserted through and fixed by being coupled to the engagement hole 7b of the locking piece 6a (FIG. 2).

In addition, the two locking pieces 6a and 6b are either one of them. By interposing an adhesive tape on one side, the peripheral edge of the insect screen 2 can be held more effectively, and the engagement of the locking pin 7a can be further enhanced.

In this way, the screen door is assembled by sequentially attaching the screen frame main bodies 1 to the vertical sides, upper and lower peripheries of the insect screen 2, as shown in FIG.

The main body 1 of the screen door frame is made of a hard synthetic resin such as vinyl chloride resin or ABS resin, and is formed into a long shape and cut into suitable dimensions in advance for the upper and lower frames and the vertical frame as shown in FIG. . In addition, a screen door formed by fixing a screen frame main body 1 to an insect screen 2 has a flat base 4 attached to a mounting part 8 of a fitting frame of a window, door, etc. or a wall surface, etc., as shown in FIGS. 4 and 5. The adhesive layer 3 is adhesively fixed by peeling off the release paper.
When installing the insect screen door assembled in this way, as shown in FIG.
In addition to fixing the flat base 4 and the holding part 6 in a horizontal state, as shown in FIG. Attachment part 8
If there is a step or the like, one side should be installed horizontally or the other side should be installed in an L-shape.

As explained in the above embodiment, the locking pin 7a and the engagement hole 7b are formed by forming the locking pin 7a on the bendable locking piece 6b having the weak portion 5 and engaging the locking piece 6a. In addition to fixing by forming the hole 7b, even if the locking piece 6a is provided with the locking pin 7a, the locking pin 10a and the locking hole 10b
It is also possible to alternately provide insect screens 2 through the peripheral edge of the insect screen 2 from both sides and engage and fix them (Fig. 8).
A screen door frame can be formed in which the insect screen 2 and the screen door frame main body 1 can be easily removed and stored.

At this time, the flat base 4 of the screen door frame main body 1 fixed to the mounting part 8 is also provided with elongated holes 13 having enlarged holes at one end at appropriate intervals, as shown in FIGS. 9A and 9B. In addition, a sheet-like mounting plate 15 having locking hooks 14 provided at suitable intervals is similarly secured to the mounting portion 8 by appropriate means, making it removable and easier to store. As shown in Figure 11B, attach the frame of the opposing window to the mounting part 8.
A mounting plate 15 is fixed to each of the window doors, and the locking hook 14 of the mounting plate 15 of the screen door frame body 1 to which the insect screen 2 is stretched is hooked to the elongated hole 13 only when the window door is opened. However, when the window is normally closed, the insect screen 2 is removed and stored together with the screen main body 1.

Furthermore, as shown in FIG. 10, this mounting plate 15 is mounted by providing an elastic packing layer 16 of elastic synthetic resin foam layer, cloth, rubber, mohair, etc. on the contact surface with the mounting portion 8. It is possible to absorb the unevenness of the portion 8, to almost completely seal the periphery of the insect screen door, and to shut off the inside and outside.

The present invention has the above-mentioned configuration, in which two flat locking pieces are provided at the tip of the flat base, one of which extends continuously from the flat base, and the other of which extends continuously from the flat base. A holding part is formed to be bendable by providing a flexible weakened part on its base side, and similarly extends integrally, and engages and fixes the peripheral edge of the insect screen between the two locking pieces. By forming this, the holding part for fixing the insect screen can be positioned not only horizontally with respect to the flat base but also bent at any angle,
In this case, since one of the two locking pieces forming one of the holding parts is provided with a weak part and is formed to be bendable, the joint between the holding part and the base becomes weak when in use. This allows the insect screen to be easily and firmly engaged while maintaining the rigidity required for the screen door frame.

Furthermore, when the insect screen is engaged and fixed, the locking piece having the weak portion is formed to be bendable and is closely attached to the other locking pieces in parallel, and the locking piece is protruded from one of the locking pieces. The locking pin is inserted into the locking piece on the opposite side, and also through the peripheral edge of the insect screen inserted into these holding parts at a substantially right angle, so that the locking pin is inserted into the locking hole of the other locking piece. It is possible to easily perform the engagement work, and it is possible to fix the insect screen while maintaining its tension. The locking piece is firmly connected to the other locking piece, thereby making it possible to obtain an insect-proof screen door that can be used for a long period of time.
