A conventional fastening fitting for a glass louver will be explained together with the glass louver with reference to FIGS. 7 to 9.

In FIGS. 7 and 9, reference numeral 1 is a horizontally long rectangular glass plate made of ordinary glass with multiple upper and lower layers, and both left and right ends of these glass plates 1 are held by fastening fittings 2, respectively. has been done.

That is, the fastening fitting 2 is composed of an integrally molded metal plate such as a stainless steel plate or an aluminum plate, and as shown in FIG. A fitting part 2b is formed, an arm 2c extends diagonally inward from the pivoting part 2b into the building, and a connecting part 2d is formed at the tip of the arm 2c, bent at a right angle from the outer edge of the end plate 2a,
An outer plate 2e that supports the outer surface of the glass plate 1, and an inner plate 2f that is divided into upper and lower portions of the pivot portion 2b and bent at right angles from the outer edge of the end plate 2a to face the inner surface of the glass plate 1. .
Upper and lower projecting pieces 2j and 2k are bent at right angles and project from the upper and lower surfaces of the glass plate 1, respectively.

The left and right ends of the glass plate 1 are the end plate 2a of the fastening fitting 2, the outer plate 2e, the inner plates 2f and 2g,
Surrounded by protruding piece 2k, elastic supporting pieces 2h, 2i, and protruding piece 2j
It is elastically supported by the outer plate 2e and the protruding piece 2k. The pivot parts 2b of the fastening fittings 2, which have multiple upper and lower stages, are pivoted to vertically elongated left and right mounting members 3 made of extruded aluminum, etc., by pivots 4, and the glass plate 1 is horizontally opened and closed between them. The connecting portions 2d of the fastening metal fittings 2 are each pivotally connected to the vertically elongated interlocking plate 5 by a connecting shaft 6.

The interlocking plate 5 is arranged in parallel to the mounting member 3 inside the building, and is configured to be raised and lowered by operating a handle. The mounting member 3 is fixed with screws 9 to the opposing surface of a vertical frame 8 of a louver frame 7 provided in a bay window of a building or the like.

This allows ventilation.

[Problem that the invention attempts to solve]

However, in the conventional louver as described above, when the glass plate 1 is open, the fastening fittings 2 have a limited hardness because the glass plate 1 is elastic as described above, and the outside side of the building The projecting pieces 2k, 2j and the holding piece 2h can be bent and raised using a screwdriver or the like, thereby allowing the glass plate 1 to be removed. Therefore, there is a problem that a thief or the like can enter the building from the outside by removing the plurality of glass plates 1. In particular, if the fastening fittings are made of aluminum plates, they can be easily bent, so this problem can be solved as mentioned above. was significant.

The present invention solves the above-mentioned problems, and provides a fixing fitting for a glass louver that makes it extremely difficult to remove the glass plate from the outside of the building, is favorable for crime prevention, and can stably hold the glass plate. The purpose is

[Means for solving problems]

The present invention includes an end plate that supports the end surface of a glass plate;
Inner and outer plates are bent from the end plate and support the inner and outer surfaces of the glass plate, respectively; elastic support pieces extend from the inner plate and separated from the end plate; and upper and lower surfaces of the glass plate. comprising upper and lower projecting pieces that come into contact with the
In the glass louver fastening fitting made of an integrally molded stainless steel plate, the end plate is provided with a pivoting portion to a mounting member, and the upper and lower projecting pieces are bent from the outer plate and the elastic support piece, A protruding piece bent from the end of the end plate is superimposed on at least one of the upper and lower protruding pieces.

[Effect]

The glass louver fastening fitting according to the present invention is
At least one of the upper and lower projecting pieces is a projecting piece that is bent from at least one of the outer plate and the elastic support piece.
Since the bent protrusions are stacked on top of each other from the ends of the end plates, the protrusions form two layers, increasing their strength, and thieves can insert a screwdriver from outside the building and bend the two layers of protrusions at the same time. Even if you do that, the fastening metal fittings are stainless steel plates, which are harder than aluminum plates, and it requires a lot of force, making it almost impossible to bend them. To bend the outer protrusion, the inner protrusion must be bent and raised after the outer protrusion has been bent.If the outer protrusion is not bent sufficiently, the inner protrusion will be bent. Since the glass panels cannot be removed by using the method, it takes more than twice as long as the conventional method to bend and raise a single layer of protruding pieces, making it extremely difficult to remove multiple glass panels from the outside of the building. possible, which is preferable for crime prevention. Furthermore, since the protrusions are made of two layers and have high strength, the holding force of the glass plate is large and stable holding is possible.

〔Example〕

Below, Figures 1 to 3 will be explained for one embodiment of the present invention.
This will be explained with reference to the figures.

In FIGS. 1 to 3, the same reference numerals as in FIGS. 7 to 9 indicate corresponding parts, and in this embodiment, the upper and lower protruding pieces 2 of the stainless steel fastening fitting
The upper and lower protruding pieces 2l and 2m bent at right angles from both the upper and lower ends of the end plate 2a are superimposed on the outer sides of the upper and lower protruding pieces 2j and 2k in the vertical direction, respectively, to form two layers of upper protruding pieces 2j and 2l and lower protruding pieces 2k. , 2m are formed, respectively, so that when the louver is closed, the load of the glass plate 1 is supported by the upper protruding pieces 2k and 2m that come into contact with the lower surface.
The construction and use of this embodiment other than those described above are the same as those of the conventional fastening fitting shown in FIGS. 7 to 9. In addition, upper and lower projecting pieces 2j, 2l, 2k, 2
When the contact surfaces of m are joined by spot welding, caulking, or adhesive, it becomes more difficult to bend with a screwdriver or the like, which will be described later, which is preferable from the viewpoint of crime prevention.

The glass louver fastening fitting according to this example is as follows:
The upper and lower projecting pieces 2j, 2l, 2k, and 2m are both inside,
Since it is formed in two outer layers and has great strength, it is almost impossible to bend the protruding pieces of the two layers at the same time with a screwdriver or the like from outside the building, thereby preventing the glass plate 1 from being removed. In addition, when the louver is closed so that the glass plate 1 is nearly vertical, the load of the glass plate 1 is supported by the two layers of lower protrusions 2k and 2m, so the lower protrusions may bend or break due to the load. This has the effect of being able to withstand a larger load and stably holding the glass plate 1 compared to the conventional one-layer lower protruding piece.

Further, FIGS. 4 to 6 show other embodiments of the present invention.

In FIGS. 4 to 6, the same reference numerals as in FIGS. 7 to 9 indicate corresponding parts, and in this embodiment, the upper and lower projecting pieces 2j and 2k of the fastening fitting 2 are bent at right angles from the tips thereof. In addition to forming the receiving pieces 2n and 2o, similarly to those shown in FIGS. 1 to 3,
Two layers of upper and lower projections 2l and 2m are formed by overlapping upper and lower projections 2j and 2k with upper and lower projections 2l and 2m bent from both the upper and lower ends of the end plate 2a. Then, the upper corner of the glass plate 1 is fitted into the groove surrounded by the upper elastic support piece 2h, the upper protruding piece 2j and the receiving piece 2m, and the outer plate 2e, the lower protruding piece 2k and the receiving piece 2o are fitted.
The lower corner of the glass plate 1 is fitted into the groove formed by the groove, so that both corners are sandwiched. In addition,
The configuration and use of this embodiment other than those described above are described in the seventh section.
This is similar to the conventional fastening metal fittings shown in FIGS. 9 to 9.

The glass louver fastening fitting according to the embodiment shown in FIGS. 4 to 6 has the advantages of the fastening fitting according to the embodiment shown in FIGS. Since the protruding pieces 2n and 2o are bent from the tip, a screwdriver etc. can be inserted into the protruding pieces 2 from the outside of the building.
This has the effect that it is difficult to insert the protruding pieces between the glass plate 1 and the holding pieces 2h and 2k, and it becomes even more difficult to bend and raise the protruding pieces.

In addition, in the present invention, even if the protrusion bent from the end of the end plate is formed only on the top or bottom, it is quite useful in preventing the glass plate from being removed from the outside. It is effective to have two layers, but it is most effective to have two layers of upper and lower protrusions.

In addition, in the description of each of the above embodiments, an acrylic plate or the like may be used instead of the glass plate 1, and the glass plate or acrylic plate may be transparent, semi-transparent,
This includes all types of opaque or colored materials.

[Effect of idea]

As explained above, according to the present invention, by superimposing a protrusion bent from the end of the end plate on at least one of the upper and lower protrusions of the conventional fixing fitting of the glass louver, the upper and lower Since at least one of the lower projecting pieces is made of two layers, the strength is increased, and thieves etc. can insert a screwdriver etc. from the outside of the building.
Even if you try to bend the projecting pieces of the two layers at the same time, the fastening metal fittings are stainless steel plates, which are harder than aluminum plates, so it requires a large amount of force, making it almost impossible to bend them. To bend the projecting pieces one layer at a time using a screwdriver, etc.,
After bending and raising the outer protrusion, the inner protrusion must be bent and raised; in this case, unless the outer protrusion is sufficiently bent and raised, the glass plate cannot be removed by bending and raising the inner protrusion. Therefore, compared to the conventional method of bending and raising a single layer of protruding pieces, it takes more than twice as long to bend and raise the protruding pieces.This makes it extremely difficult to remove a plurality of glass plates from the outside of the building, which is preferable in terms of crime prevention. Furthermore, since the protruding pieces are made of two layers and have high strength, it is possible to provide a fastening fitting that can stably hold a glass plate.
