Description

[Detailed Description of the Invention] [Industrial field of application] The present invention applies to existing window grids, handrail grids, staircase grids, landing railing grids, balconies, balconies, fences, walls,
The present invention relates to a surface lattice that can be assembled by directly using a crosspiece constituted by a vertical lattice or a horizontal lattice such as a drill.

[Prior Art] Conventionally, as a surface lattice provided on the outside of a window so that the room cannot be seen and the ventilation is not impaired, for example, there is one as shown in FIG. This surface lattice forms a rectangular frame with the upper and lower horizontal frame members 100, 100 and the left and right vertical frame members 101, 102, and the ends of each of the bent plural blade members 104 are arranged at predetermined intervals inside the vertical frame members 101, 102. The blade members 104 are inserted into the grooves 103 formed in 1. and are arranged in parallel at regular intervals for assembly. Such a surface lattice is attached by fixing its rectangular frame to the window frame or the like from the outside of the window with a stopper or the like.

[Problems to be Solved by the Invention] However, in the above surface lattice, the horizontal frame member 100, the vertical frame members 101 and 102, and the blade member 104 must be cut and assembled so as to match the size of the window to be attached. No, the assembly including this cutting work is very troublesome. In addition, in the window where the window lattice for crime prevention has already been installed,
When installing the above-mentioned surface lattice, the existing window lattice must be removed and replaced, so the construction becomes difficult, and in many cases it has to be entrusted to a specialized contractor,
There was a problem that the construction cost increased. Further, the blade member 104 used for this surface lattice is generally made of metal such as aluminum and cannot illuminate at all, and there is a problem that the room becomes dark.

[Means for Solving the Problems] In order to solve the above problems, the surface grating of the present invention is a long synthetic resin plate having a total light transmittance of 90% or more and a diffuse light transmittance of 70% or more. , The both edges in the width direction constitute upper and lower edges which are surfaces substantially parallel to each other, and the inclination between the upper and lower edges has a surface inclined at an angle of 30 ° to 40 ° with respect to the upper and lower edges. And a groove portion for fitting a part of the upper edge portion of the blade material is formed on the front surface side, and inwardly facing each other in the rear direction from the left and right sides on the rear surface side. It is characterized in that the side plates inclined in the range of ° to 15 ° each consist of a fitting made of synthetic resin and extended.

[Operation] In the surface lattice having the above-described configuration, the existing crosspiece such as a window lattice for crime prevention is used as it is, and is clamped and fixed to the crosspiece by the side plate of the fixture, and the blade member is fitted into the groove on the front side of the fixture. It is possible to assemble and install by itself, there is no need to remove the existing window lattice, and by cutting the blade material according to the window size, you can assemble a surface lattice that matches any size window You can Furthermore, by limiting the total light transmittance and diffused light transmittance of the blade material, it provides appropriate lighting and difficulty in peeping, and by limiting the angle of the inclined part of this blade material, appropriate ventilation is achieved. It is possible to secure the sex.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially cutaway perspective view showing an embodiment of a surface lattice of the present invention, FIG. 2 is a perspective view of a blade member used in this embodiment, and FIG. 3 is a blade member fitted therein. Figure 3 shows a perspective view of a mounting tool.

In the plane lattice shown in the figure, the fittings 3 are fitted to the outer two of the plurality of vertical bars 2 of the window lattice 1 provided on the aisle side of an individual house, apartment, condominium or the like, or the adjacent house side. The vertical bar
By sandwiching 2, 2 and fitting the upper edge portion 51 of the blade member 5 into the groove portion 4 provided on the front side of each fixture 3, a plurality of blade members 5 are arranged in parallel at regular intervals. It was assembled.

As shown in FIG. 2, the blade member 5 is, for example, injection-molded or extrusion-molded from a transparent synthetic resin such as a polycarbonate resin, an acrylic resin, or a nibiyl chloride resin. The thickness of the blade member 5 is about 1.5 to 3.0 mm, the width 1 of the upper edge portion 51 and the lower edge portion 52 is about 27 to 33 mm, and the total length H between the upper and lower edge portions 51 and 52 is about 80 to 90 mm. , Upper and lower edges 5
The inclined portion 53 sandwiched between the 1,52 is inclined at an angle α1. At this time, if the angle α1 of the inclined portion 53 with respect to the upper and lower edges 51, 52 becomes too large, the interval between the upper and lower blade members 5, 5 becomes large and ventilation is improved, but the overall length H of the blade member 5 becomes short and many blades are formed. Material 5 is required and angle α
If 1 is too small, the feather material 5 can be small, but
The gap between the blades 5, 5 is reduced, and ventilation is poor. This angle α1 is in the range of 30 to 40 degrees. Further, a rough surface is formed on the surface of the blade member 5 on the outdoor side by a so-called textured mold, textured roll, etc., and is semitransparent with high diffused light transmittance and high total light transmittance. It is in a state. If the roughened surface is placed outside the room, it reflects light and is not dazzling. The diffuse light transmittance can be easily adjusted by changing the size, depth, depth, etc. of the unevenness, or mixing transparent resin with different refractive index, and the total light transmittance is pigment, dye or filler. However, if the total light transmittance is too low, the room will be dark, and if the diffuse light transmittance is too low, the room will be easily visible from the outside. It is semi-transparent with a light transmittance of 70% or more. At this time, in order to increase the diffused light transmittance, it is possible to make it fine and have a rough uneven surface, or to make both the front and back surfaces of the blade member 5 rough.
Also, as a semi-transparent blade material, a surface of the blade material 5 may be laminated with an acrylic film having good weather resistance, a fluorine film or a coloring film having good weather resistance and stain resistance, or may be colored by containing a dye or the like. Good.

The fixture 3 for attaching the blade member 5 is injection-molded from synthetic resin such as AES resin, hard polyvinyl chloride resin or acrylic resin. As shown in FIG. A holding portion 30 having a groove portion 4 whose lower end is opened so that the blade material 5 can be arranged is formed at three positions at regular intervals, and the upper edge portion 51 of the blade material 5 is fitted into each groove portion 4. It is like this. The groove width of each groove portion 4 is approximately the same as the plate thickness t of the blade member 5 to be fitted, but in the state where the blade member 5 is not fitted, the opening width g of the lower end opening 4a of the groove portion 4 is The blade member 5 is formed into a taper shape that is narrower than the plate thickness of the blade member 5, and when the blade member 5 is attached to the groove portion 4, the lower portion of the upper edge portion 51 of the blade member 5 is elastically pressed by the pressing portion 30 to surely. It can be fitted. The inner surface of the lower end opening 4a of the groove portion 4 is chamfered to facilitate insertion and attachment of the blade material.
Further, if the opening width g of the lower end opening is too narrow, the blade member 5
It becomes difficult to mount the upper edge portion 51 of the blade member 5, and if the blade member 5 is too wide, the blade member 5 is likely to fall off. Therefore, the opening width g is about 40 of the plate thickness t of the blade member 5.
About 80% is preferable. Furthermore, the lower end 4a of the opening of each groove 4
Immediately below each of the blades, there are provided protrusions 31 each having a substantially triangular shape and having a protrusion angle α2 that is substantially the same as the inclination angle α1 of the blade member 5, so that the inclined portion 53 of the blade member 5 that is fitted can be securely attached. It supports and prevents the groove 4 from falling off. Here, if the inclination angle α1 of the blade member 5 is equal to the protrusion angle α2 of the protrusion 31, the blade member 5 can only be pressed by the holding portion 30 of the fixture 3, and the groove portion 4 can be slid vertically or laterally. Therefore, the protrusion angle α2 of the protrusion 31 is made larger than the inclination angle α1 of the blade member 5 so that the blade member 5 and the protrusion 31 are elastically contacted with each other to be securely fitted and fixed in the groove portion 4 and the blade member 5 is detached. May be prevented. The groove 4 and the protrusion 31 are connected to each other at three positions at a fixed interval L1 and the total length L is 230.
The length is about 250 mm, and when the fixtures 3 are attached to the existing rails 2, the length is such that a plurality of sets of the fixtures 3 can be fitted vertically to most of the existing rails 2.
If a plurality of sets of fittings 3 are not attached exactly, it is easy to cut and respond on the groove portion 4 for one blade material or for two blades because it is a resin fitting. .

On the other hand, the side plates 32, 32 are provided on the left and right rear sides of the fixture 3 at an angle α3.
Are vertically narrowed inward, and substantially hemispherical ridges 33, 33 are provided on the upper and lower edges of the rear end so as to face the inner surface. The ridges 33, 33 act as stoppers that prevent the fixture 3 from slipping out of the crosspiece. The opening width w1 and the inner surface width w2 between the ridges 33, 33 are set such that the opening width w1 is 8 to 12 mm and the inner surface width w2 is 16 to 20 mm, or the opening width w1 is 14 to 18 mm and the inner surface width is w2 is 24 to 28 mm, the angle α3 of the side plates 32, 32 is set to the range of 5 to 15 degrees,
The size is such that most of the existing crosspieces 2 can be clamped.
Further, if the overall width W of the fixture 3 is too wide, the balance with the crosspieces 2 to be clamped becomes poor, and the appearance is also impaired. Therefore, the overall width W is preferably about 20 to 25 mm, or about 28 to 35 mm. If the side plates 32 and 32 are present, the thickness of the side plates 32 and 32 is sufficient, and when the vertical bar 2 is sandwiched between the side plates 32 and 32, problems such as cracks are unlikely to occur.

Further, if the overlapping portion S of the upper edge portion 51 and the lower edge portion 52 of the blade member 5 fitted in each groove portion 4 on the plane is too large, the total light transmittance at the overlapping portion is lowered and it becomes dark. On the contrary, if the overlapping portion is small, the inside can be easily seen. Therefore, the interval L1 between the groove portions 4 is adjusted to overlap the overlapping portion S of the blade member 5.
Is preferably about 5 to 10 mm.

As shown in FIG. 4, in the surface lattice having the above-described structure, first, the upper edge portion 51 of the blade member 5 is inserted obliquely from below to the opening lower end 4a of each corresponding groove portion 4 of the set of fixtures 3, and the pressing portion is provided. Three blade members 5 are fitted into the groove portions 4 by 30, respectively. This feather material 5
Since the blade member 5 is made of synthetic resin, it is extremely easy to fit into the groove portion 4 due to its elasticity. Further, the inclination angle α1 of the inclined portion 53 of the blade member 5 and the protrusion of the mounting portion 3
Since the protrusion angle α2 of the blade 31 is substantially the same, the protrusion 31 surely supports the inclined portion 53 of the blade member 5, and the pressing portion 30 of the groove portion 4 presses the upper edge portion 51 of the blade member 5 so that the blade member 5 is pressed. 5 is surely prevented from falling off.

After the three blades 5 are fitted to the pair of fixtures 3 at regular intervals, the rear side plates 32, 32 of the fixture 3 are pressed against the existing vertical bars 2 to press the vertical bars 2 to the side plates. It is clamped by 32 and 32, and the fixture 3 is clamped and fixed to the vertical rail 2. Hereinafter, three blades 5 are provided for each of the plurality of sets of fixtures 3 according to the length of the vertical bar 2.
Are fitted at regular intervals, and the rear side plate 3 of the fixture 3 is mounted in the same manner as above.
It can be clamped and fixed to the vertical rail 2 with 2,32. Therefore, without removing the existing vertical rail 2, the vertical rail 2 can be used as it is to easily assemble the surface lattice.

Further, in the fixture 3 used for the surface lattice of the present invention, since the semicircular protrusions 33, 33 are formed at the tips of the side plates 32, 32 for sandwiching the vertical bar 2, the fitting to the vertical bar 2 is performed. Wearing is smooth and at the same time it can be prevented from coming off. Further, as the vertical bar 2 which can be elastically clamped, the size from the vertical bar 2'shown in FIG. 5 to the vertical bar 2 "shown in FIG. 6 is firmly fitted by the ridge 33 of the side plate 32. However, as shown in Fig. 7, a rectangular crosspiece 2 having a width smaller than the inner surface width w2 can of course be fitted and used, so that it can be clamped and fixed to most vertical crosspieces 2 ... Will be high.

Further, since the blade member 5 has a high total light transmittance and a high diffused light transmittance as described above, it becomes a surface grating which is sufficiently bright on the indoor side and does not allow the inside of the room to be seen through.

Here, all the blade members 5 of the fixture 3 of the above-described embodiment are fitted and fixed in the horizontal direction. However, when the crosspiece is provided in the horizontal direction, the fixture 3 is fitted and fixed in the horizontal crosspiece. By doing so, it is of course possible to dispose and fix the blade member 5 in the vertical direction.

[Effect of the Invention] As is clear from the above description, in the area lattice of the present invention,
The existing rail can be used as it is and clamped and fixed by the side plate of the fixture, eliminating the waste of removing the existing rail as in the past and improving the workability and changing the cutting dimension of the blade material. By doing so, an area lattice of any size can be easily assembled, which is advantageous in that it is economical and versatile.
Further, by fitting the blade member in the groove portion of the fixture, it is possible to provide appropriate lighting and difficulty in peeping, and also to obtain appropriate ventilation.
