Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structure for holding a net on a frame material in a mesh door formed by stretching a mesh on a mesh door frame in which the frame material is framed in a rectangular shape.

[Conventional technology]

As shown in Japanese Utility Model Publication No. 55-26474, a structure in which a long mesh member is press-fitted together with a mesh into the recessed portion of the frame material to hold the mesh on the frame.

As shown in Japanese Utility Model Publication No. 49-3477, a flexible shielding tape is attached to the peripheral portion of the mesh in the longitudinal direction, and the shielding tape is pushed into the opening of the frame material to make the mesh elastic by the shielding tape. The structure that holds the frame material.

[Problems to be solved by the device]

With the former holding structure, when the mesh stopper is pressed in together with the mesh, strong tension may act on the mesh, or the mesh may be pressed against the edge portion of the recessed portion of the frame material and the mesh may break. Alternatively, it is necessary to press the net stop member into the recessed portion in a state where the net is tensioned and tensioned so that the net is uniformly tensioned without sagging, and the work of attaching the net to the frame material It is very troublesome and requires a lot of skill, and it takes a considerable amount of time to stretch the net on the screen frame, and sometimes the net is not evenly tensioned and wrinkles may occur on the net.

In the latter holding structure, by pushing the shielding tape into the opening of the frame material, the elasticity of the shielding tape gives tension to the net and allows the net to be attached to the screen door frame in a tense state, compared to the former holding structure. Although the work of attaching the net becomes easier, the shielding tape is continuous in the longitudinal direction, so a large force is required to deform the shielding tape, and the end of the net is large in the opening of the frame material. The work must be pushed in with force, and the work is difficult to do.Besides, the shielding tape is directly connected to the net by the tacks, and the tension of the net acts on the tacks intensively, so the net can be frayed or cut. Not only that, the tension of the mesh is strong at the connecting portion with the shielding tape and weak between the adjacent connecting portions, so that the mesh cannot be evenly tensioned and wrinkles may occur.

Therefore, an object of the present invention is to provide a mesh holding structure in a mesh door that can solve the above-mentioned problems.

[Means and Actions for Solving the Problems]

On the frame member 2 of the screen door frame 1, a net mounting recess 13 having a receiving piece 14 on the opening side is formed, and a tape member 4 is fixed to the peripheral edge of the net 3 in the longitudinal direction. A plurality of engaging elements 5 provided with elastic pieces 8 are attached at intervals in the longitudinal direction such that the elastic pieces 8 are separated from the surface of the tape member 4 and face the net 3 side, and the tape member 4 and the engaging elements 5 are attached. A net holding structure in which the net 3 is held in the frame member 2 by the elastic force of the elastic piece 8 by facing the inside of the net mounting concave portion 13 of the frame member 2 to contact the elastic piece 8 with the receiving piece 14.

As a result, the elastic piece 8 can be elastically deformed with a small force by holding the tape member 4 and pushed into the net mounting concave portion 13 of the frame member 2, and the tension by the elastic piece 8 can be applied.
The mesh 3 can be evenly transmitted to the mesh 3 through the so that the mesh 3 can be tensioned evenly without wrinkling.

〔Example〕

As shown in FIG. 5, a screen door frame 1 is formed by vertically and horizontally framing a frame member 2, and a screen 3 is stretched over the screen door frame 1.

As shown in FIGS. 2 and 3, one end of the tape member 4 in the width direction is fixed to the periphery of the mesh 3 by welding at a high frequency over the longitudinal direction, and the engaging member 5 is attached to the tape member 4 by the thread 6. The engaging member 5 is sewn, and includes a U-shaped mounting portion 7 and an elastic piece 8. The mounting portion 7 is sewn to the other end in the width direction of the tape member 4 so that the elastic piece 8 is a tape member. It faces away from the surface of No. 4 and faces the net 3 side.

The engaging element 5 is formed by bending a linear member 9 made of a monofilament such as polyester, nylon or the like, or a metal wire material such as stainless, and the adjacent engaging elements 5 are continuously defined by the linear member 9 and the intervals are uniquely determined. Since the plurality of engaging elements 5 can be simultaneously set and sewn on the other end of the tape member 4 in the width direction, the sewing operation can be facilitated.

The tape member 4 is made of cloth, nylon-coated cloth, or the like.

As shown in FIG. 1, the frame member 2 integrally has one side plate 10 and the other side plate 11 connected by a connecting plate 12 and has a net mounting recessed portion 13.
Hook-shaped receiving pieces 14, 14 are integrally formed on the opening end side of the net mounting concave portion 13 of the one side plate 10 and the other side plate 11 in the longitudinal direction, and an opening 15 is formed between the receiving pieces 14, 14. The opening width of the opening 15 is slightly larger than that of the mounting portion 7 of the engaging member 5, and the elastic member 8 is received by the elastic member 8 by pushing the engaging member 5 together with the tape member 4 into the mesh mounting recess 13 from the opening 15. The net 3 is pressed against 14, and the elastic force of the elastic piece 8 pulls the net 3 in the direction of the arrow A to move it in the longitudinal direction of the frame member 2 for fine adjustment to hold the net 3 on the frame member 2, and as shown in FIG. 3 is stretched over the screen frame 1.

FIGS. 6 (a) and 6 (b) show a modified example of the frame member 2, in which the frame member main body 20 and the ridge 21 form the frame member 2, and the ridge 21 is detachable from the frame member main body 20 and the receiving piece. 22 is provided and is shown in FIG. 6 (a).
By pressing the receiving piece 22 of the ridge 21 against the elastic piece 8 of the engaging element 5 as shown in FIG.
As shown in FIG. 2B, the mesh 3 is held on the frame member 2 by the elastic force of the engaging element 5.

As a result, the opening width of the opening 15 can be reduced and the gap B with the tape member 4 can be reduced, so that insects and the like can be prevented from entering the net mounting recess 13.

Since the tape member 4 protrudes from the opening 15 to the outside, when the net 3 is bent by wind or the like, the net 3 is opened in the opening of the frame member 2.
Since it does not touch 15, the net 3 will not be damaged even if the opening width of the opening 15 is reduced as described above.

FIG. 7 shows a first modified example of the engaging element 5, in which a pair of elastic pieces 8 are provided in the mounting portion 7 so as to project to both front and back sides of the tape member 4, and the pair of elastic pieces 8 and 8 are used as a pair of receiving pieces. They are pressed against 14 and 14, respectively.

By doing so, the force for pulling the net 3 can be increased and the net 3 can be tensioned with a strong force.

In FIG. 7, the tape member 4 has a width that does not protrude from the opening 15, and since the tape member 4 is not seen from the front side of the screen door, it has a neat design and a good appearance.

FIG. 8 shows a second modified example of the engaging element 5, which is formed by bending the linear member 9 and has a mounting portion 7 and an elastic piece 8.

FIG. 9 shows a third modified example of the engaging element 5, which is formed by bending a highly elastic plate material 23 such as a leaf spring into a shape having a U-shaped attachment portion 7 and an elastic piece 8, and the attachment portion 7 is a tape. Member 4
It is attached by fitting it into the other widthwise end of the and tightening it.

FIG. 10 shows a fourth modified example of the engaging element 5, which is a plate-shaped attachment portion 7 and a tongue-shaped elastic piece 8 which are made of a highly elastic plate material 24 such as a leaf spring.
And the mounting portion 7 is mounted on the surface of the tape member 4 by high frequency welding or adhesive.

FIG. 11 shows a fifth modified example of the engaging element 5, in which the elastic piece 8 is bent in a direction parallel to the surface of the tape member 4, whereby a sufficient elastic force is obtained, and the elastic piece 8 is Since the size can be reduced, the frame member 2 can be downsized.

Further, the engaging element 5 may be a shape memory alloy which is stretched and deformed at a high temperature and is reduced to its original state at a low temperature.

By doing so, the elastic piece 8 can be stretched because the temperature is high in the summer when the screen door is used, and strong tension can be applied to the net 3, and the elastic piece 8 can be reduced because the temperature is low in the winter when the screen is not used. Net 3
Since a weak tension is applied to the screen, the screen can be made to last for a long time without deterioration of the screen.

[Effect of device]

Since the net 3 is held by the frame member 2 by the elastic force of the elastic piece 8 of the engaging element 5, it is not necessary to pull the net 3 when the net 3 is stretched, and a large tension is applied to the net 3. It suffices to push the engaging member 5 together with the tape member 4 into the mesh mounting concave portion 13 of the frame member 2 without being pressed against the edge portion of the frame member, and to engage the tape member 4 fixed to the peripheral edge of the mesh member 3. Since a plurality of mating elements 5 are provided at intervals in the longitudinal direction, the engaging elements 5 become short and the elastic piece 8 can be elastically deformed by a small force, and moreover, the engaging element 5 of the frame member 2 is held by the tape member 4. Since it can be pushed into the net mounting recessed portion 13, the two work together to facilitate the work of holding the net 3 on the frame member 2,
Further, the tension of the elastic piece 8 of the engaging element 5 is transmitted to the net 3 through the tape member 4, and the tension of the net 3 becomes substantially uniform in the longitudinal direction, so that the net 3 may be partially frayed or cut. In addition to the absence of wrinkles, the net 3 can be stretched uniformly without wrinkling.

Therefore, together with them, the net tensioning work is facilitated, and the screen door can be quickly assembled without requiring skill.
