Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a holding structure for insect-proof nets, etc., in which the edges of insect-proof nets, sheets, etc. are fixed to the lip grooves of the crosspieces of fittings such as screen doors, etc., using press-fasteners. In addition to making it possible to properly attach insect repellent nets, etc., the attachment work is easy.
Moreover, it has been improved so that it does not come off easily after it is fixed.

[Conventional technology]

Conventional holding devices such as insect nets have two legs projecting symmetrically from one side of a band-shaped base, and short locking protrusions are provided on the outside of each of these two legs. This was common.

[Problem that the invention attempts to solve]

In the above-mentioned conventional example, an insect repellent net, etc. is placed on the lip groove of the crosspiece, and the band-shaped base is parallel to the insect repellent net and pressed from above to secure it. Since the net may be swallowed by insects, it is necessary to loosen the insect net slightly to secure it. Therefore, in the case of an accordion-style screen door as in this example, if the insect screen is slackened when attached, the insect screen will remain sagging when the screen door is closed, resulting in an unsightly appearance. However, there was a problem that if the amount of slack was reduced, it would become impossible to close the door. Also, if the locking protrusion on the leg is long, you will have to hit it with a wooden hammer or press with a lot of force, making it difficult to lock, and if it is short, it will be easier to lock, but it will easily come off after it has been locked. There was a problem with this.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a structure for holding down insect nets, etc., in which the edge of the insect screen, etc. is fixed to the crosspiece B with a holding device A, in which the crosspiece B has a One engagement protrusion 10 and second engagement protrusion 11
are arranged oppositely to form a lip groove 12, and the lip groove 1
2, the presser stopper A is provided with two legs 2 and 4 protruding from one side of a substantially band-shaped base 1, and
is provided with a locking protrusion 3 that protrudes outward, and the leg portion 4 is provided with an insertion protrusion 5 that also protrudes outward,
The insertion protrusion 5 is configured to engage deeply with the second engagement protrusion 11, and the locking protrusion 3 is configured to engage shallowly with the first engagement protrusion 10. 12 and engaged with the second engagement protrusion 11, the locking protrusion 3 can be elastically locked and fixed to the first engagement protrusion 10.

【Example】

Next, an embodiment of the present invention (in this embodiment, an accordion-type insect screen door) will be described based on the drawings. The insect-proof screen door N is made up of a movable crosspiece 13, middle crosspieces 14 and 15, and a fixed-side crosspiece B with an insect-proof screen 16 stretched thereon. The insect screen 16 includes a movable crosspiece 13 and middle crosspieces 14 and 15.
It is fixed in advance, so when installing it on the building,
One end of the insect screen 16 is fixed to the crosspiece B with a holding device A in accordance with the width of the opening of the building. The retaining structure of the present invention is composed of a retaining member A and a crosspiece B on the fixed side of the insect-proof screen door N. The holding stopper A has two legs 2 and 4 protruding from one side of a substantially band-shaped base 1 at a predetermined interval, and a rather short locking protrusion 3 facing outward on the leg 2. The leg portion 4 is also provided with a slightly longer insertion protrusion 5 facing outward. Base 1 on leg 2 side
Although a protrusion 6 for removal connected to is provided, this protrusion 6 is not always necessary. The crosspiece B has side walls 8 and 9 protruding from both ends of the bottom wall 7, and a slightly long first engagement protrusion 10 at the tip of the side wall 8.
A second engagement protrusion 11, which is also slightly longer, is provided at the tip of the side wall 9 to face inward, and a lip groove 12 is formed. In this embodiment, only the locking protrusion 3 is formed shorter than the insertion protrusion 5, the second engagement protrusion 11, and the first engagement protrusion 10. The one shown in FIG. 5 is another embodiment of the present invention, in which both the locking protrusion 3 of the holding stopper A and the first engaging protrusion 10 of the crosspiece B are slightly shorter. , the locking protrusion 3 and the first engagement protrusion 10 are formed shorter than the insertion protrusion 5 and the second engagement protrusion 11. The one shown in FIG. 6 is also another embodiment of the present invention, in which the locking protrusion 3 of the holding stopper A is inserted into the insertion protrusion 5.
The first engaging protrusion 10 of the crosspiece B is made slightly shorter, and only the first engaging protrusion 10 is longer than the insertion protrusion 5 and the second engaging protrusion 11. and is formed shorter than the locking protrusion 3. In short, both the insertion protrusion 5 and the second engagement protrusion 11 are formed long so that both are in a deep engagement state, and either or both of the locking protrusion 3 and the first engagement protrusion 10 are formed long. is formed short, and after the insertion protrusion 5 deeply engages with the second engagement protrusion 11, the locking protrusion 3 elastically locks with the first engagement protrusion 10, and both are in a shallow locking state. It is designed to be. Although the present embodiment has been described using an accordion-type insect screen door, it is of course possible to use a regular insect screen door, and it is also possible to attach a sheet or the like to the screen.

[Effect]

Next, the fastening method of the present invention will be explained. First, as shown in FIG. 4, the insertion protrusion 5 of the presser stopper A is inserted into the second engagement protrusion 11 side from the lip groove 12 of the crosspiece B and engaged deeply. At this time, since the insect screen 16 is swallowed from the stretched side (the right side in FIG. 4), the width of the insect screen door N hardly changes. Next, when the leg portion 2 side of the holding stopper A is pressed, one or both of the locking protrusion 3 and the first engagement protrusion 10 are formed short (in the embodiment shown in FIG. 4). Since only the locking protrusion 3 is formed short, the locking protrusion 3 is easily elastically locked to the first engagement protrusion 10, and the insect screen 16 is stretched. At this time, since the insertion protrusion 5 and the second engagement protrusion 11 are engaged, the insect screen 16 will not be swallowed from the stretched side (the right side in FIG. 4), so the width dimension of the insect screen door N remains almost unchanged. The process is completed by cutting off the remaining insect screen 16 at the end. The engagement state between the insertion protrusion 5 and the second engagement protrusion 11 is as follows:
The depth becomes deeper than the locked state between the locking protrusion 3 and the first engagement protrusion 10. The insect screen 16 is pulled on the side where the insertion protrusion 5 and the second engagement protrusion 11 are engaged, that is, the side that is deeply engaged, so it is difficult to come off, and
Since the insertion protrusion 5 can be inserted into the second engagement protrusion 11 side and this deep engagement can be performed first, fastening can also be done easily.

[Effect of the idea]

As described above, according to the present invention, there is almost no change in the width dimension when installing an insect screen, etc., so the effect is that any number of people can perform the installation work without requiring skill. There is. Furthermore, after deeply inserting the slightly long insertion protrusion of the holding stopper into the crosspiece and engaging the second engagement protrusion,
Since the locking protrusion is elastically locked, it is easy to fasten without using any tools, and once fastened, it will not come off easily during normal use, and there is no need to remove the insect screen etc. after fastening. If there is a problem, if the holding stopper is removed from the locking protrusion side (lower side in FIG. 3), the locking state between the two is shallow, so it can be easily removed, which is an excellent effect.
