Description

[Detailed Description of the Invention] [Industrial application] The present invention is applicable to, for example, existing window lattices, handrail lattices, staircase lattices, landing handrail lattices, balconies, balconies, fences, walls, fences, etc. The present invention relates to a surface lattice that is assembled by using a crosspiece composed of a lattice.

[Prior Art] Conventionally, as a surface lattice provided on the outside of a window so that the interior cannot be seen and the ventilation is not impaired, for example,
There are some as shown in Figure 14. 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.

In the surface lattice as described above, in order to match the dimensions of the window frame to be attached, the horizontal frame member 100, the vertical frame members 101, 102 is inserted into each groove 103 formed at a predetermined interval, each blade member 104. It is usual that the rectangular frames are assembled in parallel at regular intervals, and the rectangular frame is fixedly attached to the window frame or the like from the outside of the window with a stopper or the like.

However, in the above area lattice, the horizontal frame member 100 and the vertical frame members 101 and 102 are arranged so as to match the dimensions of the window frame to be attached.
Also, the blade member 104 had to be cut and assembled, and the assembly work including this cutting was troublesome. In addition, when attaching the above-mentioned area lattice to a window that has already been provided with a crime prevention window lattice, etc., it is necessary to remove the existing window lattice etc. and replace it, so if you have to entrust it to a specialized contractor However, there was a problem that the construction cost was high. Therefore, the applicant has fixed a fixture made of synthetic resin having a pair of left and right sandwiching pieces by sandwiching and fixing the existing crosspiece to the crosspiece by elastically sandwiching the existing crosspiece with the sandwiching pieces. We devised a surface lattice having a structure in which a blade member is fitted in a groove formed on the front surface side and a plurality of blade members are attached in parallel at regular intervals.
Such an area grid can be easily used by an amateur even by using an existing crosspiece such as an existing window grid for crime prevention as it is, fixing a fixture to the crosspiece, and fitting a blade member into a groove of the fixture. It can be assembled and installed, there is no need to remove the existing window lattice,
In addition, it is convenient to assemble a plane lattice matching windows of various sizes simply by cutting the blade material according to the size of the window.

[Problems to be Solved by the Invention] However, in the case of elastically sandwiching and fixing the fixture to an existing crosspiece by utilizing the elastic force of the sandwiching piece of the synthetic resin fixture as in the above-mentioned surface lattice. Is that the radiant heat of the sun's rays causes the synthetic resin fixture to creep over time and the elastic force of the sandwiching piece is reduced. There was a risk that the fixture would fall off the crosspiece when such things act.

It is also possible to increase the clamping strength of the fixture to the crosspiece by fixing the fixture to the crosspiece with double-sided adhesive tape, but in this case, it is troublesome to attach the double-sided adhesive tape to the crosspiece. was there. Further, since the pressure-sensitive adhesive tape itself is not so durable, the adhesive strength is lowered over time, and the fixture cannot be attached and fixed to the crosspiece, and there is a possibility that the fixture may fall off from the crosspiece.

The present invention has been made in view of the above, and an object of the present invention is to provide a surface lattice in which the attachment tool can be prevented from falling off while maintaining the advantages of the previously proposed surface lattice.

[Means for Solving the Problems] In order to solve the above problems, in the surface lattice of the present invention, a fixture having a groove formed on the front side is externally fitted to the crosspiece and the crosspieces are formed by the left and right side plates of the fixture. In addition to elastically sandwiching from both sides, the left and right side plates of the metal sandwiching spring material externally fitted to the fixture further elastically sandwich the left and right side plates of the fixture from both sides, and the blade member is fitted into the groove of the fixture. In addition, a plurality of blade members are arranged in parallel at regular intervals.

[Operation] In the surface lattice having the above-mentioned configuration, while using the existing crosspiece such as a window grating for crime prevention as it is, the fixture is externally fitted and the crosspiece is elastically sandwiched from both sides by the left and right side plates of the fixture, A metal sandwiching spring member is externally fitted to the fixture, and the left and right side plates of the spring member are further elastically sandwiched between the left and right side plates of the fixture, and the blade member is fitted in the groove on the front side of the fixture. It can be easily assembled by an amateur just by wearing it, there is no need to remove the existing window grid, and if the blade material is cut according to the window size, it becomes a surface grid that fits any size window. Moreover, since the fixture is attached to the crosspiece by utilizing the elastic holding force of the left and right side plates of the fixture and the elastic holding force of the metal holding spring material, even if the elastic holding force of the fixture side plate decreases due to creep, the spring Since the elastic clamping force of the side plate of the material does not decrease, the fixture can be securely clamped and fixed to the crosspiece.

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

FIG. 1 is an exploded perspective view of a surface lattice according to an embodiment of the present invention in which the blade material is partially omitted, FIG. 2 is a partial perspective view of the blade material used in the embodiment, and FIG. 3 is the same embodiment. FIG. 3 is a perspective view of a fixture and a metal holding spring member used for the above.

The surface lattice shown in the figure is a fixture for two vertical rails 2 on both sides of the plurality of vertical rails 2 of the window lattice 1 provided on the window of the aisle side of an individual house, apartment, condominium or the like, or the adjacent house side. 3 is externally fitted to the left and right side plates to elastically sandwich the vertical bar 2 from both sides, and a metal clamping spring member 6 is externally fitted to the fixture 3 from the rear of the vertical bar 2 By further elastically sandwiching the left and right side plates of the fixture 3 from both sides with the left and right side plates of the blade 3, and by fitting the upper edge portion 51 of the blade member 5 into the respective groove portions 4 formed on the front side of each fixture 3. A plurality of blade members 5 are arranged in parallel at regular intervals and assembled.

The vane member 5 is formed by injection molding or extrusion molding of transparent synthetic resin such as polycarbonate resin, acrylic resin, polyvinyl chloride resin, or the like. As shown in FIG.
It has a bent shape with an inclined portion 53 between a vertical upper edge portion 51 and a lower edge portion 52. Examples of preferable dimensions of the vane material 5 include a thickness of about 1.5 to 3.0 mm, a vertical width H of about 80 to 90 mm, a width h of the upper edge portion 51 and the lower edge portion 52 of about 20 to 25 mm, and an upper edge portion 51. And the step size l between the lower edge 52 and the lower edge 52 is about 27 to 33 mm,
The angle α ₁ of the inclined portion 53 is about 30 to 40 degrees. If the angle α ₁ of the inclined portion 53 is increased, the interval between the upper and lower blade members 5, 5 is increased and ventilation is improved, but the vertical width H of the blade member 5 is shortened and a large number of blade members 5 are required. If the angle α ₁ is reduced, the number of blades 5 can be reduced, but the blades 5,
Since the interval of 5 becomes small and the ventilation is deteriorated, it is appropriate that the angle α ₁ of the inclined portion 53 is about 30 to 40 degrees as described above.

Further, at least one surface of the blade member 5 is roughened with a so-called wrinkled die or a wrinkled roll to provide a semitransparent state in which diffuse light transmittance and total light transmittance are high. Regarding the diffused light transmittance and the total light transmittance of the blade material 5, it is preferable that the former is 70% or more and the latter is 90% or more. If the total light transmittance is lower than 90%, the interior becomes easier to see, and the interior becomes darker. The diffused light transmittance can be adjusted relatively easily by changing the size, depth, density, etc. of the unevenness and mixing transparent resin with different refractive index. If it is formed with a density, the diffused light transmittance becomes high. Further, the total light transmittance can be adjusted relatively easily by changing the mixing amount of the pigment, the dye, or the filler, and if the mixing amount is reduced, the total light transmittance becomes high. The semi-transparent vane material 5 having at least one surface roughened as described above reflects light when mounted with the rough surface as the outdoor side and is not dazzling, but if there is a possibility that dust or the like may accumulate, the unevenness may occur. The rough surface may be attached to the inside of the room. Further, if necessary, an acrylic film having good weather resistance, a fluorine film having good weather resistance, and a staining film having good stain resistance may be laminated on the surface of the blade member 5, or a dye or the like may be contained to obtain various colors. It may be colored.

The fixture 3 to which the blade member 5 is attached is, for example, injection-molded of synthetic resin such as AES resin, hard polyvinyl chloride resin, acrylic resin, etc., and has a lower end opened on the front side as shown in FIG. The pressing portions 30 having the groove portions 4 are provided at three positions at regular intervals, and the upper edge portion of the blade member 5 is provided in each groove portion 4.
51 is to be fitted. The groove width of each groove portion 4 is substantially the same as the plate thickness t of the blade member 5 to be fitted,
When the blade member 5 is not fitted, the opening width g of the lower end opening 4a of the groove portion 4 is formed in a taper shape narrower than the plate thickness of the blade member 5, and when the blade member 5 is attached to the groove portion 4. Further, the lower part of the upper edge portion 51 of the blade member 5 is elastically pressed by the pressing portion 30 so that the blade member 5 can be securely fitted. And the groove 4
The inner surface of the lower end opening 4a is chamfered to facilitate insertion and mounting of the blade member 5. The lower end opening width g of the groove portion 4 is preferably about 40 to 80% of the plate thickness t of the blade member 5,
If it is narrower than this, it will be difficult to insert the upper edge 51 of the blade material,
If it becomes wide, there is a problem that the blade member 5 is likely to fall off. Immediately below the opening lower end 4a of each groove 4, a substantially triangular protrusion 31 having a protrusion angle α ₂ substantially equal to the inclination angle α ₁ of the blade member 5 is provided so as to project. The slanted portion 53 of No. 5 is supported by the projection 31 so as not to fall off from the groove portion 4. The inclination angle α of the blade member 5
_If the projection angles α ₂ of ₁ and the projection 31 are equal, the blade member 5 is only pressed by the pressing portion 30 of the mounting 3, and the groove portion 4 may slide in the vertical direction or the horizontal direction.
Even if the blade member 5 and the protrusion 31 are elastically contacted with each other by making the protrusion angle α ₂ of the blade member 5 slightly larger than the inclination angle α _{1 of} the blade member 5, and the blade member 5 is securely fitted and fixed in the groove portion 4 so as not to slide. Good. The groove portions 4 and the protrusions 31 are formed at three upper and lower positions on the front surface of the fixture 3 with a constant interval L _{1 so} that one blade 3 can be fitted with three blades 5.
Further, it is preferable that the total length L of the fixture 3 is about 230 to 250 mm. With such a length, most of the existing crosspieces 2
It is possible to fit a plurality of fixtures 3 up and down with respect to each other. If the blades cannot be fitted exactly, the blades may be cut on one or two blades 4 to be dimensionally matched. For such cutting work, the fixture 3 is made of synthetic resin. Easy to do

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 α ₃
Are extended in the upper and lower parts in a state of being narrowed inward, respectively, and the ridges 33, 3 with a substantially hemispherical cross section are formed on the upper and lower edges of the rear end.
3 are extended facing each other. The ridges 33, 33 not only serve as guides for attaching the fixture 3 to the crosspiece 2 and facilitate the fitting work, but also act as stoppers for preventing the fixture 3 from coming out of the crosspiece 2. is there.
Regarding the opening width w ₁ and the inner surface width w ₂ between the ridges 33, 33, the opening width w ₁ is 8 to 12 mm and the inner surface width w ₂ is 16 to ₂₀ mm, or the opening width w ₁ is 14 mm. ~18mm, an inner width w ₂ 24~28mm
And set the angle α _{3 of the} side plates 32, 32 in the range of 5 to 15 degrees,
The size is such that most of the existing crosspieces 2 can be clamped.
Further, if the total width W of the fixture 3 is too wide, the balance with the crosspiece 2 to be clamped becomes poor and the appearance is also impaired. Therefore, the total 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 upper edge portion 51 and the lower edge portion 31 of the blade member 5 fitted in the respective groove portions 4 are too large in the overlap portion, the total light transmittance at the overlap portion is lowered and the light becomes dark. If the overlap portion is small, the inside can be easily seen through the gap. Therefore, it is preferable to adjust the interval L ₁ between the groove portions 4 to set the overlap dimension of the blade member 5 to about 5 to 10 mm.

Further, clamping ridges 35, 35 to which the metallic clamping spring member 6 is fitted are provided at substantially central portions of the side plates 32, 32 on the left and right rear sides, respectively. The sandwiching projection 35 is formed by a plurality of projections 34 that stand up substantially vertically at the front and form a slope toward the rear in a substantially sawtooth shape. The clamping projections 35, 35 may be provided so as to project over the entire length of the side plates 32, 32, but they may be provided only at the portion clamped by the clamping spring material 6, and as in the embodiment, they are vertically arranged at the central portion. Length L ₂ is 10
It suffices if it is projected so as to be about 25 mm.
Incidentally, when a plurality of positions of the fixture 3 are clamped by the clamping spring member 6, the clamping projections 35, 35 are made to correspond to the clamping positions.
May be provided at a plurality of locations. Further, as shown in FIG. 4, if the protrusion length T of each protrusion 34 from the side plate 32 is long, it becomes difficult to hold the protrusion 34 by the holding spring material 6, and if the projection length T is short, on the contrary, the holding spring material 6 is used.
The protrusion length T is about 0.8 to 1.2 mm.
Several protrusions with the distance D between each protrusion 34 being about 1.5 to 3.0 mm
It is a ridge 35 for pinching which forms 34.

Clamping protrusions 35, 35 formed on the side plates 32, 32 of the fixture 3
The metal holding spring member 6 fitted on the plate is, for example, a plate thickness t ₁
Is a plate material such as stainless steel of about 0.6 to 1.5 mm bent in a substantially U shape to have spring properties.
Hook-shaped holding pieces 61, 61 are formed at the front end edges of the 2, 62, respectively, and are bent inwardly at an acute angle to form a hook shape. The width w ₃ of the rear clamping spring member 6 20~25mm about in consideration of the overall width W of the fitting 3, or is about 28～35Mm, front width w ₄ is slightly narrower 18 than the width w ₃ of the rear The front sandwiching pieces 61, 61 are spread to be about 23 mm or about 26 to 33 mm to facilitate elastic contact. The elastic force of the sandwiching spring member 6 is determined by the vertical width L ₃ in relation to the plate thickness t _{1. If} the vertical width L ₃ is too long, the elastic force becomes high and it becomes difficult to attach it to the fixture 3, and it is too short. Therefore, it is preferable to set the vertical width L ₃ to about 7 to 20 mm because a sufficient elastic force cannot be obtained and the fixture 3 cannot be reliably held. Further, the inward bending angle α ₄ of the sandwiching pieces 61, 61 is
The sandwiching pieces 61, 61 facilitate the sandwiching of the projections 34 of the sandwiching ridges 35, 35 of the side plates 32, 32 of the fixture 3, respectively, and fold them at about 45 to 60 degrees so that they will not come off once they are sandwiched. It has been tuned.

The surface lattice having the above-described structure is provided with two vertical bars 2 on both sides of the vertical rails 2 of the existing window grid 1 by the side plates 32, 32 of the plurality of sets (two sets in the embodiment) of the fixtures 3, 3. , 2 both sides of which are elastically clamped, and further, the protrusions 34, 34 of the clamping projections 35, 35 of the side plates 32, 32 of each fixture 3 and the front clamping pieces 61, 61 of the clamping spring member 6
And as shown in FIG. 4 so that the left and right side plates 32, 32 of each fixture 3 are further elastically sandwiched from both sides by the sandwiching pieces 61, 61 of the left and right side plates 62, 62 of the spring member 6, and each attachment is performed. The blade member 5 can be assembled simply by inserting the upper end edge 51 of the blade member 5 from the lower end 4a of the opening of the groove portion 4 of the tool 3 and inserting the blade member 5 into the groove portion 4. Since the blade member 5 is made of synthetic resin, it is extremely easy to fit the blade member 5 into the groove 4.
Therefore, it is not necessary to remove the existing window lattice or the like, and even an amateur can easily assemble and construct the surface lattice.

Further, in the blade member 5 fitted in each groove 4 of the fixture 3, the inclined portion 53 of the blade member 5 is supported by the projection 31 of each fixture 3, and the upper edge portion of the blade member 5 is also supported. Since 51 is pressed by the pressing portion 30 of the fixture 3, it does not fall off even if it receives wind pressure or the like. Moreover, since the blade member 5 is a semi-transparent blade member having a high total light transmittance and a high diffuse light transmittance, it is possible to keep the inside of the room bright and to sufficiently prevent the outside from seeing through the room. be able to. Further, by cutting the blade material 5 in accordance with the window size, it is possible to form a plane lattice corresponding to a window of any size, which is versatile.

In the surface lattice of the present invention, the metal sandwiching spring member 6 is fitted behind the fixture 3 holding the crosspiece 2, so that the side plate of the fixture 3 is fitted.
The elastic clamping force of 32, 32 and the elastic clamping force of the side plates 62, 62 of the metallic clamping spring member 6 can securely clamp the fixture 3 on the crosspiece 2. Therefore, even if the elastic holding force of the side plates 32, 32 of the fixture 3 disappears by creeping due to radiant heat of the sun's rays and the like, and disappears, the fixture 3 still retains the side plate of the metal holding spring material 6. The elastic clamping force of 62, 62 maintains the state of being clamped and fixed to the crosspiece 2, and the fixture 3 does not fall off even if wind pressure or the like acts on the blade member 5. Therefore, as shown in FIG. 5, even when the vertical bar 2a having a width larger than the opening width w _{1 of the} fixture 3 and smaller than the inner surface width w ₂ is clamped, the side plates 62, 62 of the metal clamping spring member 6 are clamped. By the elastic clamping force of, the fixture 3 can be reliably clamped and fixed to the crosspiece 2a. Further, as shown in FIG. 6, even if the vertical bar 2b has a rectangular cross section that protrudes from the opening of the fixture 3, the clamping pieces 61, 61 of the metal clamping spring member 6 are clamped by the fixture 3. By simply fitting the projections 35, 35 on the rear side projections 34, 34, the fixture 3 can be securely clamped and fixed so as not to fall off the crosspiece 2b. Even if the fixture 3 is securely clamped and fixed to assemble the surface lattice, the versatility is increased.

The surface lattice of the present invention clamps and fixes the fixture together with the metal clamping spring member on the crosspiece as described above, but the following fixtures and metal clamping spring members should be used. You can also FIG. 7 is a perspective view of a fixture 3a and a metal holding spring member 6a showing another embodiment. This fixture 3a has a rectangular recess 35 in which a plurality of oval recesses 34a are provided on the left and right side plates 32, 32 in place of the clamping projections 35, 35 of the fixture 3.
a and 35a are formed respectively. On the other hand, the metal holding spring member 6a is bent in a substantially U-shape with a vertical width substantially the same as that of the rectangular recesses 35a, 35a of the fixture 3a.
The tongue with the rear side cut and raised inward in the approximate center of the front of the
63 and 63 are formed respectively. The other structure is the same as that of the above-described embodiment, and the same members are designated by the same reference numerals and the description thereof is omitted. With such a fixture 3a and the sandwiching spring material 6a, the side plates 62, 62 of the sandwiching spring material 6a are fitted into the rectangular recesses 35a, 35a of the fixture 3a that sandwiches the crosspiece 2 and the inside of the recesses 35a, 35a are fitted. Tongue pieces 63, 63 protruding inward of the holding spring material 6a in the recesses 34a, 34a
The fittings 3a can be securely clamped and fixed to the crosspiece 2 by fitting the respective fittings.

Further, as shown in FIG. 8, a metal holding spring member 6b can be fitted in front of the fixture 3b. In this fixture 3b, for example, a recess 36 having a substantially U-shape connecting the side plates 32, 32 below the central protrusion 31 and the front plate portion and having a depth substantially equal to the plate thickness of the holding spring member 6b is provided. It is recessed. Both ends on the front side of the recess 36 are formed into curved surfaces, so that the sandwiching spring member 6b can be easily fitted therein. On the other hand, the sandwiching spring member 6b has a substantially U-shape with the rear opening, and the side plates 32, 32 of the fixture 3b.
Are vertically narrowed at an angle α ₃ and are narrowed inward, so the opening width w1 and inner surface width of the fixture 3
or a 6~10mm the rear opening width w ₅ in consideration of w2, or, and 12 to 18 mm, the front overall width W of the fitting 3 the total width w ₆
Is molded to about 20 to 25 mm or about 28 to 35 mm. Further, guide pieces 64, 64 bent outward are formed at the rear end edges of the side plates 63, 63, so that the fitting tool 3b can be fitted into the recess 36 smoothly. Even with such a fixture 3b and the sandwiching spring material 6b, the fixture 3b is used for the rail 2
The side plates 63, 63 of the holding spring material 6b after being clamped to the fixture 3b.
By fitting the fitting 3b into the recess 36 from the front side, the fixture 3b can be securely clamped to the crosspiece 2. Before sandwiching the fixture 3b on the crosspiece 2, the sandwiching spring member 6b is fitted into the recess 36 of the fixture 3b, and the fixture 3b sandwiched by the sandwiching spring member 6b is attached to the crosspiece 2. It can also be sandwiched between. In this way, when the holding spring material 6b is fitted to the fitting 3b before the fitting 3b is fixed to the rail 2, the holding spring 6b is clamped and fixed on the rail 2.
There is an advantage that the work rate is improved as compared with the case of fitting.

Therefore, like the mounting tool 3c shown in FIG. 9, it may be integrally molded in advance with a substantially U-shaped metal holding spring member 6c having an outer shape substantially equal to the outer shape of the mounting tool 3c embedded therein. .
If the holding spring material 6c is embedded in the fixture 3c in advance in this manner, it is not necessary to fit the holding spring material 6c into the fixture 3c, and thus the work of fitting the holding spring material into the fixture is performed. As a result, the area lattice can be assembled without the need for an assembly work.

FIG. 10 is an exploded perspective view of a blade member of another embodiment with a part thereof omitted, and FIG. 11 is a sectional view taken along the line JJ of FIG. The fixture 3d used in this embodiment is the same as the fixture 3 except that no protrusions or recesses for fitting the metal sandwiching spring material 3d to the left and right tensions 32, 32 are formed.
Since they are substantially the same as the above, the same members are denoted by the same reference numerals and the description thereof is omitted here. On the other hand, metal clamping spring material 6d
Has a U-shaped cross section with an open rear,
It has side plates 67, 67 which are slightly longer than the 3d side plates 32, 32, and their rear edges are bent inwardly to form sandwiching pieces 68, 68. The sandwiching pieces 68, 68 are engaged with ridges 33, 33 having a substantially hemispherical cross section formed on the rear end edge of the fixture 3d, and the protruding length thereof is shorter than the ridges 33, 33. Has become.

In this embodiment, after the fixture 3d is clamped on the crosspiece 2, the clamping spring material 6d is fitted from the front of the fixture 3d, and the clamping pieces 68, 68 of the clamping spring material 6d are fitted into the convex portions 33, 33 of the fixture 3d. By engaging 68, the fixture 3d is securely clamped and fixed to the crosspiece 2. Therefore, in this embodiment, since the fixture 3d is securely sandwiched and fixed to the crosspiece 2 by the sandwiching spring member 6d, the fixture 3d is fixed.
Even if the elastic clamping force of the side plates 32, 32 of the blade disappears, the elastic pinching force of the left and right side plates 67, 67 of the clamping spring member 6d maintains the state in which the crosspiece 2 is clamped, and the blade member 5 receives wind pressure or the like. The fixture 3d does not fall off even if is applied.

Furthermore, if the attachment 3d and the holding spring member 6d are used, the 12th
As shown in the drawing, even if the cross-section is a rectangular vertical bar 2b that protrudes from the opening of the fixture 3d, the holding pieces 68, 68 of the holding spring material 6d are used to hold the rear end ridges 33, 33 of the fixture 3d. Thus, the fixture 3d can be securely clamped on the crosspiece 2d by clamping the. Therefore, if the holding spring member 6d is used, if it can be held by the fixture 3d,
The fixture 3d can be reliably clamped and fixed to the crosspieces of various shapes, and the versatility is greatly increased.

Further, in order to more securely sandwich and fix the fixture 3d on the vertical crosspiece 2b protruding from the opening of the fixture 3d, a holding spring member 6d 'shown in FIG. 13 may be used. The holding spring material 6
In d ', the side plates 67', 67 'are extended so as to be slightly longer than the depth of the crosspiece 2b, and the bending length of the holding pieces 68', 68 'at the rear end edge is lengthened to make the holding pieces 68'. The rear end of the crosspiece 2b can be clamped by the tips of 68 '. When such a holding spring member 6d 'is used, as compared with the case where the holding member 6d is held by the holding spring member 6d shown in FIG. 12, the holding member 3d and the rail 2b can be held together as a unit, and the rail 2b can be securely held. The fixture 3d can be clamped and fixed to.

Here, all the blade members 5 of the fixtures 3 ... In the above-mentioned embodiment are shown to be fitted and fixed in the horizontal direction. However, when the crosspieces are provided in the horizontal direction, the fixtures 3 ... Of course, it is also possible to dispose and fix the blade member 5 in the vertical direction by fitting and fixing it on the horizontal rail.

[Effects of the Invention] As is clear from the above description, the surface lattice of the present invention can be easily assembled by an amateur by using the existing crosspiece as it is, and there is no need to remove the existing window lattice.
By cutting the blade material in accordance with the window size, it is possible to easily assemble and install a surface lattice of any size, which is simple, economical, and versatile. Moreover, since the fixture is firmly attached to the crosspiece by the elastic holding force of the left and right side plates and the elastic holding force of the left and right side plates of the metal holding spring material externally fitted to the fixture, the left and right side plates of the fixture are creeped. Even when the elastic clamping force of the spring is reduced, the fixture is maintained in a state of being reliably clamped and fixed to the crosspiece by the elastic clamping force of the left and right side plates of the spring material, and there is a remarkable effect that there is no fear of falling off.
