Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a shutter curtain fixing device that fixes building shutters in a closed state. It is related to.

0002

[Conventional technology]

An example of a shutter curtain fixing device for building shutters is shown in Figure 5. There is. FIG. 5 is a view from the indoor side with the shutter curtain 16 closed. , 17 are guide rails provided on both sides of the entrance.

0003 Slide bars 18, 18 are provided symmetrically on the indoor side of the shutter curtain 16. , the central ends of both slide bars 18, 18 are attached to both ends of the lock lever 19, respectively. pivot. By rotating the lock lever 19, both the slide bars 18, 18 slides horizontally and engages and disengages from the guide rail 17.

0004 Thus, with the slide bars 18, 18 engaged with the guide rail 17, the shaft is The curtain 16 is fixed, and the slide bars 18, 18 are moved from the guide rail 17. In the detached state, the shutter curtain 16 can move up and down.

[0005]

[Problem that the idea aims to solve]

As mentioned above, conventional shutter curtain fixing devices require guide rails. In addition, the shutter curtain itself supports mechanisms such as slide bars and lock levers. It must have the strength and rigidity to hold it.

[0006] However, in recent years, with emphasis on the design of buildings, buildings without guide rails or In response to diversifying customer requests, we have changed the shutter curtain material to mesh material. , canvas, etc. are being used. In this way, the material of the shutter curtain Mesh or canvas, etc., are non-rigid and weak against local loads. In this case, the above-mentioned mechanisms such as slide bars and lock levers cannot be installed. do not have. Therefore, the conventional shutter curtain fixing device described above is This product cannot be used for objects that are not rigid or whose shutter curtains are made of flexible materials. There was a problem that there was no.

[0007] This invention was developed in view of the above circumstances, and was developed in the case where there is no guide rail or the shutter curtain is bent. We provide a shutter curtain fixing device that can be fixed without any problem even if the material is flexible. This is what we are trying to provide.

[0008]

[Means to solve the problem]

This invention has hook metal fittings installed on the seat plate unit installed at the lower end of the shutter curtain. Then, bury the key case in the floor in the position corresponding to the hook metal fitting, and it can be inserted into and removed from the key case. The hook metal fitting is capable of being engaged with a functional key plate. .

[0009]

[Effect]

To secure the shutter curtain in the closed position, pull it down and With the seat plate unit grounded, insert and engage the key plate into the key case. , the seat plate unit engages the hook fitting of the seat plate unit with the key plate; It is fixed to the floor via a key plate. When the shutter curtain is open, Remove the rate from the key case.

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0011] In FIGS. 1 to 3, 1 is a mesh material shutter curtain, and 2 is the shutter curtain. The seat plate unit is shown attached to the lower end of the unit. At the required location of the seat plate unit 2 A U-shaped hook fitting 3 is provided so as to be able to rise and fall freely, and can be engaged with each hook fitting 3. A key plate 6 is provided.

0012 A key case 5 is buried in the floor 4. The key case 5 has a flat shape into which the key plate 6 is inserted. The gap 7 has a boot-like shape, and the gap 7 is perpendicular to the shutter curtain 1. It is formed in-plane, and the length of the upper end opening is sufficiently longer than the protrusion length of the protrusion 8 at the bottom of the gap. It's lengthened.

[0013] A foot portion 9 is formed at the lower part of the key plate 6 and engages with the protrusion 8. A hook portion 10 that protrudes toward the shutter curtain is formed on the top of the key plate 6. A recess 11 into which the hook fitting 3 is fitted from above is formed in the portion 10.

[0014] Further, in FIG. 2, reference numeral 12 denotes a lock that restrains the movement of the key plate 6 within the key case 5. It is a cup plate.

[0015] When fixing the lower end of the shutter curtain 1, the following procedure may be used.

[0016] First, the shutter curtain 1 is lowered and the seat plate unit 2 is grounded to the floor. . While pulling up the hook fitting 3, inserting the key plate 6 into the key case 5, After inserting it, slide it to the shutter curtain 1 side. The foot portion 9 of the key plate 6 While engaging with the protrusion 8, a gap is created on the opposite side of the shutter curtain 1 of the key plate 6. . By fitting the lock plate 12 into the gap, the key plate 6 is fixed. be done.

[0017] Next, if the hook metal fitting 3 is lowered and fitted into the recess 11, the shutter cover The lower end of the marten 1 is horizontally moved upward and downward by the engagement between the hook fitting 3 and the recess 11. The direction is restricted by the hook part 10 of the key plate 6, and the lower end of the shutter curtain 1 is Fixed to the floor.

[0018] Note that a leaf spring or the like is provided along the recess 11, and the hook fitting 3 is fitted into the recess 11. If it slides into contact with the leaf spring, the frictional force between the plate spring and the recess 11 The fitted state with the hook metal fitting 3 becomes more stable.

[0019] In addition, when the shutter curtain is open, the key plate 6 and the lock plate 12 is in a state of escape. The gap into which the key plate 6 and lock plate 12 are inserted is a blank space. Since it is in the form of a slit, there is no practical problem even if it is left as it is, as shown in Figure 4. A dummy plate 13 of various types may be fitted. In addition, at the corner of the dummy plate 13, A hook portion 14 is formed to facilitate removal.

[0020] In the above example, the material of the shutter curtain was mesh, but the material of the shutter curtain was mesh. Can also be applied to general shutter curtains made of canvas or metal slats. Of course, it is possible.

[0021]

[Effect of the idea]

As described above, according to the present invention, even without a guide rail, rigidity and strength can be improved. Even shutter curtains made of non-flexible material can be securely fixed to the building side. Ru.
