Description

  The present invention relates to a shoji.

  Conventionally, a shoji (inner shoji) is used on the indoor side of the outdoor joinery (see, for example, Patent Document 1).

JP-A-8-151853

  However, in order to enhance the heat insulation effect, the conventional inner shoji uses double-layer vacuum glass or double-layer resin glass, so that (double glass) is very heavy and difficult to handle. Moreover, the multilayer vacuum glass and the multilayer resin glass are expensive, and there is a problem that the manufacturing cost increases.

  In particular, since the conventional inner shingles for remodeling are manufactured by custom-ordering double-glazed glass, there is a problem in that accurate measurement accuracy is required and delivery time. Therefore, in most cases, a single glass having a thickness of 3 mm to 4 mm is used, which is still heavy and has a poor heat insulating effect, and has a high risk of breakage of the glass.

  Resin is generally used as the crosspiece of the inner shoji. For this reason, the vertical rail of the inner shoji requires a certain or more (expected) thickness dimension from the viewpoint of preventing glass breakage due to deflection. However, when installing retrofitted internal shojis other than new constructions, it was necessary to provide additional frames around the frame due to the lack of (expected) thickness dimensions, and there was a problem that costs increased.

  From the environmental point of view, wood is the best material for the plinth of the shoji, but a plastic pouch made of synthetic resin is used to reduce costs, and it was not a suitable material in terms of indoor humidity adjustment.

  Traditionally, paper with shoji paper on both sides of the kumiko has been used as a heat insulating shoji, but the brightness of the room is only half that of single-sided so it can only be used in a bright room. , There was a drawback that if it was torn, the heat insulation was lost. Moreover, since the thickness of the paper was less than 0.3 mm and was thin, the heat insulating effect was poor.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a safe and inexpensive inner pouch that has a high heat insulating effect and is difficult to break.

  The inner shoji according to the present invention includes a rectangular frame, a lattice-like assembly constructed on the inner side of the frame, and two transparent or semi-transparent thin resin sheet bodies attached to the front and back surfaces of the assembly. The resin sheet body is formed slightly smaller than the assembly in consideration of expansion and contraction due to heat, and the insulation air layer is surrounded by the assembly and the two resin sheet bodies. The multilayer body formed as described above is provided.

Further, the assembly has a rectangular turning edge that can be fitted in an annular groove provided on the inner side of the frame body, and the resin sheet body is not pasted on both the front and back surfaces of the assembly. The resin sheet body is slidably held by being overlapped and fitted with the peripheral edge of the resin sheet body together with the turning edge in the annular groove.
Further, the multilayer body includes an opening preventing member for preventing the resin sheet and the assembly from being separated, and the opening preventing member is a rivet type having a head portion and a shaft portion, and A through hole for inserting and locking the shaft portion is formed in the resin sheet body, and the through hole is formed larger than the shaft diameter of the shaft portion so that the shaft portion can be loosely fitted. It is what.
Moreover, the thickness dimension of the said heat insulation air layer formed with the said 2 resin sheet body is set to 8 mm-18 mm.

Further, the assembly has a rectangular turning edge capable of contacting the inner surface of the frame body, and the resin sheet body is overlapped in a non-sticking manner on both the front and back surfaces of the assembly. The inner pressing edge and the outer pressing edge for slidably holding the outer peripheral edge portion of the resin sheet body are fixed to the frame body.
In addition, an appendage is provided on the inner surface of the frame body, and the resin sheet body is superposed in a non-sticking manner on both the assembly and the front and back surfaces of the appendage, and the outer peripheral edge of the resin sheet body The inner pressing edge and the outer pressing edge that hold the part slidably are fixed to the frame body.
In addition, an L-shaped receiving member having an insertion groove for holding the sheet body is attached to the inner side surface of the frame body, and the resin sheet body is stacked in a non-sticking manner on each of the front and back surfaces of the assembly. In addition, the outer peripheral edge portion of the resin sheet body is slidably inserted into and held in the insertion groove of the L-shaped receiving member.

  According to the present invention, it is inexpensive, hardly broken, and very light, bright and excellent in daylighting, and can easily improve heat insulation. The expansion and contraction of the resin sheet body can be absorbed to prevent bending.

It is BB expanded sectional drawing of FIG. It is CC expanded fracture | rupture sectional drawing of FIG. It is a principal part expanded sectional view which showed other embodiment of this invention. It is a principal part expanded sectional view which showed another embodiment of this invention.

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments.
As shown in FIG. 1 and FIG. 2, the inner scabbard of the present invention includes a rectangular frame 2, a grid-like braid 1 constructed inside the frame 2, and a transparent attached to both front and back surfaces of the braid 1. Thru | or two translucent thin resin sheet bodies 3 and 3 are provided.
Referring to FIGS. 3 and 4, the inner sheet of the present invention is such that the resin sheet bodies 3 and 3 are formed slightly smaller than the assembly 1 in consideration of expansion and contraction due to heat. The multilayered body 10 formed by surrounding the heat insulating air layer 11 with the resin sheet bodies 3 and 3 is provided.

  The thickness dimension of the resin sheet body 3 is set to 0.5 mm to 2.0 mm. The resin sheet 3 may be transparent or semi-transparent and hard to break, and is preferably made of a synthetic resin such as polycarbonate. Polycarbonate, in particular, has a thermal conductivity of about 1/4 times that of glass, is excellent in heat insulation, has a high total light transmittance of about 95%, and is optimal from the viewpoint of lighting. In other words, the resin sheet 3 has a thickness dimension required to obtain a heat insulating property equivalent to that of the conventional glass, which is about 1/4 times that of the conventional glass, and its weight is 1 / Since it is about 8 times, it is light and easy to handle. In addition, in consideration of the expansion and contraction due to heat of the resin sheet bodies 3 and 3, the formation is slightly smaller than the assembly 1, taking into account the elasticity and bending of the resin sheet bodies 3 and 3 due to the heat. The width and height are set slightly shorter than the width and height of the brace 1.

The assembly 1 has a rectangular turning edge 14 that can be fitted into an annular groove 20 provided inside the frame body 2, and the resin sheet body 3 is provided on each of the front and back surfaces of the assembly 1. 3 are superposed in a non-sticking manner.
In consideration of the elasticity and bending of the resin sheet bodies 3 and 3 due to the heat of the resin sheet bodies 3 and 3, the inner shoji is not attached to the braid 1 with an adhesive or glue, and the outer peripheral edge portion 30 of the resin sheet body 3. (Both) The turning edge 14 is fitted in the annular groove 20 to hold the resin sheet 3 slidably.
The resin sheet bodies 3, 3 are held so as to be close to and away from each other with a minute gap 9, 9 with respect to the innermost surface 20 </ b> A of the annular groove 20. The gaps 9 and 9 are provided to absorb the expansion and contraction of the resin sheet bodies 3 and 3.

  The frame 2 is formed by assembling left and right vertical bars 21, 21 and an upper horizontal bar 22 and a lower horizontal bar 22 ′ into a rectangular shape (using wood screws or the like). The multilayer body 10 is held by an annular groove 20 provided on the inner surface. The frame body 2 has a clearance (clearance) between the sliding contact surface 20B of the annular groove 20 and the multilayer body 10 (the outer surface of the resin sheet bodies 3 and 3) of about 0.2 mm (set as small as possible). In addition, the circulation of the air in the heat insulating air layer 11 inside the multilayer body 10 is prevented, and the deformation and condensation of the resin sheet body 3 are prevented with respect to the expansion / contraction of the air due to the temperature difference.

As shown in FIGS. 2 and 5, the multilayer body 10 is provided with an opening preventing member 15 for preventing the resin sheet bodies 3 and 3 and the braid 1 from being separated.
The opening stop member 15 is a rivet type having a head portion 15B and a shaft portion 15A. Specifically, it is preferable to use a flat head driving rod or a wood screw.
Further, the resin sheet body 3 is formed with a through hole 16 through which the shaft portion 15A is inserted and locked. Further, the through hole 16 allows the shaft portion 15A to be loosely fitted and has a shaft diameter larger than that of the shaft portion 15A. Is also formed large.
For example, when the thickness dimension of the resin sheet body 3 is 0.5 mm, the through holes 16 are formed at a rate of about one place for every approximately 0.3 square meters of the area of the resin sheet body 3. 15 is inserted into the brace 1 through the shaft portion 15A through the through-hole 16, and the resin sheet body 3 is lightly pressed to prevent the opening. The through-hole 16 is a so-called fool hole that is provided with a size about twice as large as the shaft diameter of the shaft portion 15 </ b> A, and is formed in advance before the stopper member 15 is driven.

The braid 1 is formed in a lattice shape having an insulator 12 and a transverse element 13, and includes a rectangular turning edge 14 surrounding the periphery of the lattice composed of the insulator 12 and the transverse element 13. Kumiko 1, with the thickness T _1, holding the distance between the two resin sheet bodies 3,3. That is, the thickness dimension T ₁ of the heat insulating air layer 11 formed by the two resin sheet bodies 3 and 3 is held equal to the thickness dimension T ₁ of the assembly 1 over the entire multilayer body 10. ing.

The inner sash of the present invention, the thickness dimension _{T 1} of the heat insulating air layer 11 is set to 8Mm～18mm. More preferably, it is good to set to 10 mm-12 mm.
With this configuration, the frame width of the opening for installing the shoji can be set to 37 mm to 43 mm while ensuring the strength of the braid 1, which is suitable for use as a (sluggish) internal shoji. In other words, the heat insulating air layer 11, when the thickness T ₁ is set to be smaller than 8 mm, can not be secured intensity of muntin 1 is sufficiently, and if the thickness T ₁ is set larger than 18 mm, the frame The width becomes large and an additional frame is required, which increases the cost.

The material of the assembly 1 is not limited, but if it is made of wood, it has a low thermal conductivity and is suitable for adjusting the humidity of the heat insulating air layer 11 of the multilayer body 10, so that it is easy to condense. Suitable for installation.
In addition, the resin sheet 3 can be easily cut with a cutter knife, a saw, or the like, and no special processing such as sealing is required. Therefore, the resin sheet 3 can be dimensioned easily and accurately, and the delivery time can be shortened.
Although not shown in the drawings, as an alternative to the braid 1, two resin sheet bodies 3, 3 stacked on each of the front and back surfaces are used by using a separator with a double-sided suction cup, or a liner and a driving rod or a screw. , Fixed at a predetermined interval adapted to the thickness dimension, and around the resin sheet bodies 3 and 3, corresponding to the thickness dimension T ₁ of the heat insulating air layer 11 (the length dimension of the separator or liner) May be incorporated to form the multilayer body 10.

Here, the method for assembling the inner impeller according to the present invention will be described. As shown in FIGS. 3 and 4, the multi-layer body 10 is inserted from the back side into the frame 2 assembled in advance in a rectangular shape. Then, using a 3 mm to 4 mm thick strip plate member 23 made of hard-to-break wood, decorative veneer board or synthetic wood, etc., it is attached to the surface side of the wooden core material 24 to make an L-shaped crosspiece (in cross-sectional view) After the multilayer body 10 is fitted from the back side, a pressing plate member 25 made of a decorative veneer board or synthetic wood having a thickness of about 3 mm is attached to the back side of the wooden core 24 (with a double-sided tape, etc.) Even when the multilayer body 10 is fitted in the annular groove 20 and the frame 2 is integrally held to hold the turning edge 14 of the assembly 1, even if the thickness dimension T ₁ of the assembly ₁ is relatively small. Have enough safety. The frame body 2 is made of a base material processed so as to be L-shaped (in cross section), and a pressing plate member made of a decorative veneer plate or synthetic wood having a thickness of about 2.5 mm to 3 mm is provided on the back side thereof. It may be pasted (not shown).

  Although not shown in the drawings, as another method of assembling the inner impingement element of the present invention, a configuration may be adopted in which a Grechan is attached around the multilayer body 10 and fitted into the annular groove 20. In this case, it is preferable to use a decorative veneer plate having a thickness of about 2.5 mm or synthetic wood as the band plate member 23 and the presser plate member 25.

  Further, as shown in FIG. 4, the portion where the upper horizontal rail 22 of the frame body 2 is fitted into the different duck is fitted with the core material 24 and the airtight packing 24 </ b> A in the cage's ridge, A shoulder portion 26 is formed on the top. The airtight packing 24A is fixed to the upper part of the upper horizontal rail 22 of the frame body 2 (with a double-sided tape or the like). In addition, the edge of the Kamoi will be the minimum frame width if a 3 mm to 4 mm thick hard-to-break wood, or a veneer made of decorative veneer or synthetic timber is used, and the gap between the Kamoi's inner walls (partitions) will be reduced. This facilitates the installation of a semicircular airtight member (not shown) between the central frames.

  The material of the braid 1 and the frame 2 is preferably wood from the Japanese climate and environment, but a synthetic resin molded product may be used, and it can be manufactured at a lower cost, and the multilayer body 10 can be reliably secured. Even when the resin sheet bodies 3 and 3 expand and contract, they are not restrained and can be easily fitted and assembled with good workability.

The inner shoji of the present invention can be applied to an existing (paper) shoji, and as shown in FIG. 6, two resin sheet bodies 3 and 3 are stuck on the front and back surfaces of the existing shoji 1 The multilayer body 10 can also be formed.
In the case where the existing shoji assembly 1 has the turning edge 14, the (rectangular) turning edge 14 abuts the inner surface of the frame 2, and a resin sheet is provided on each of the front and back surfaces of the assembly 1. The bodies 3 and 3 are overlapped in a non-sticking manner, and the inner pressing edge 18A and the outer pressing edge 18B that hold the outer peripheral edge portion 30 of the resin sheet body 3 slidably are fixed to the frame body 2.
The inner pressing edge 18A and the outer pressing edge 18B are fixed to the inner surface of the frame body 2 (with double-sided tape or wood screws) while pressing (lightly) the resin sheet body 3. The resin sheet body 3 is slidably held with respect to the assembly 1, and is allowed to approach and separate from the frame body 2 with a gap 9.

  In addition, when the existing shoji assembly has no turning edge, an appendage 17 is provided on the inner surface of the frame 2, and both the front and back surfaces of the assembly 1 and the appendage 17 are provided. The resin sheet bodies 3 and 3 are overlapped in a non-sticking manner, and the inner pressing edge 18A and the outer pressing edge 18B that slidably hold the outer peripheral edge portion 30 of the resin sheet body 3 are fixed to the frame body 2. The method for attaching the inner pushing edge 18A and the outer pushing edge 18B is the same as described above.

As an alternative method in the case where there is no turning edge in the existing shoji assembly, as shown in FIG. 7, an L-shaped receiving member 19 having an insertion groove 19A for holding the sheet body is attached to the inner surface of the frame body 2. In addition, the resin sheet bodies 3 and 3 are superposed on the front and back surfaces of the assembly 1 in a non-sticking manner, and the outer peripheral edge 30 of the resin sheet body 3 is slidably contacted with the insertion groove 19A of the L-shaped receiving member 19. Insert and hold freely.
The L-shaped receiving member 19 includes a receiving angle 29 and a pressing angle 28 that can be fitted to the receiving angle 29. By fitting the holding angle 28 to the receiving angle 29, the outer peripheral edge portion of the resin sheet body 3. An insertion groove 19 </ b> A that holds the slidable contact 30 is formed. The L-shaped receiving member 19 fixes one side of the receiving angle 29 to the braid 1 while fixing the other side to the inner surface of the frame body 2 (with an adhesive, glue, double-sided tape, etc.). 3 is applied to the inner surface of one side of the angle 29, and is pressed into the other side of the receiving angle 29 while being pressed (lightly) against the resin sheet body 3. .

  In other words, the inner shoji according to the present invention is (mainly) a double double shoji that is provided inside the outdoor joinery, and can be applied to existing paper shoji, and is thin, light, safe, and insulated. It is highly effective. Furthermore, the use of two transparent or translucent thin resin sheet bodies 3 and 3 can make the room brighter, hardly break, and can be easily manufactured at low cost. Moreover, because wood is mainly used, it is suitable for the living environment and has excellent humidity control. By reducing the expected size of the shoji frame so as not to provide an additional frame, the cost can be reduced and the shoji does not protrude on the room side. Furthermore, considering cost reduction, a synthetic resin shoji may be used as long as it does not condense. The multilayer body 10 can use the thin resin sheet bodies 3 and 3 by using the assembly 1.

  As described above, the inner impingement according to the present invention includes a rectangular frame 2, a lattice-shaped braid 1 structured inside the frame 2, and a transparent or translucent attached to both the front and back surfaces of the braid 1. Two thin resin sheet bodies 3, 3 are provided, and the resin sheet bodies 3, 3 are formed slightly smaller than the assembly 1 in consideration of expansion and contraction due to heat. Since the multi-layer body 10 formed by surrounding the heat insulating air layer 11 with the resin sheet bodies 3 and 3 is provided, it is inexpensive, hardly broken, and very light, bright and excellent in daylighting. In addition, the heat insulating air layer 11 of the multilayer body 10 has a remarkable heat insulating property and can improve the sound insulating property. The expansion and contraction of the resin sheet body 3 (which is relatively easy to expand) can be absorbed to prevent bending.

  The assembly 1 has a rectangular turning edge 14 that can be fitted into an annular groove 20 provided inside the frame 2, and the resin sheet body 3 is provided on each of the front and back surfaces of the assembly 1. Since the resin sheet body 3 is slidably held in the annular groove 20, the resin sheet body 3 is slidably held together with the outer peripheral edge 30 of the resin sheet body 3 and the peripheral edge 30 of the resin sheet body 3. Corresponding to the expansion and contraction of the bodies 3 and 3, it is possible to prevent deformation and bending.

  In addition, the multilayer body 10 includes an opening preventing member 15 for preventing the resin sheet bodies 3 and 3 and the assembly 1 from being separated, and the opening preventing member 15 includes a head portion 15B and a shaft portion 15A. The through-hole 16 for inserting and locking the shaft portion 15A is formed in the resin sheet body 3, and the through-hole 16 allows the shaft portion 15A to be loosely fitted. Since it is formed to be larger than the shaft diameter, the resin sheet bodies 3 and 3 can be lightly pressed to be prevented from being separated from the assembly 1 and the expansion and contraction of the resin sheet bodies 3 and 3 can be absorbed.

Further, the heat insulating air layer 11 formed by the two resin sheets 3, 3 a thickness _{T 1,} since the set 8Mm～18mm, can sufficiently secure the strength of the muntin 1, and, The frame width of the joinery can be set to a comparatively small value of 37 mm to 43 mm, which is suitable for use as a retractable nausea.

  Further, the assembly 1 has a rectangular turning edge 14 capable of contacting the inner surface of the frame 2, and the resin sheet bodies 3, 3 are not attached to the front and back surfaces of the assembly 1. Since the inner pressing edge 18A and the outer pressing edge 18B that slidably hold the outer peripheral edge portion 30 of the resin sheet body 3 are fixed to the frame body 2, they are also applicable to an existing kumiko shoji (paper shoji). Therefore, it is possible to improve heat insulation more easily at a lower cost, and it is possible to reliably cope with expansion and contraction of the resin sheet bodies 3 and 3 and prevent deformation and bending.

  In addition, an appendage 17 is provided on the inner surface of the frame body 2, and the resin sheet bodies 3, 3 are overlapped in a non-sticking manner on both the front and back surfaces of the assembly 1 and the appendage 17. Since the inner pushing edge 18A and the outer pushing edge 18B that hold the outer peripheral edge 30 of the slidable member are fixed to the frame 2, the present invention is applicable even when the existing kumoji shoji (paper shoji) has no turning edge. Therefore, it is possible to improve heat insulation more easily at a lower cost, and it is possible to reliably cope with expansion and contraction of the resin sheet bodies 3 and 3 and prevent deformation and bending.

  Further, an L-shaped receiving member 19 having an insertion groove 19A for holding the sheet body is attached to the inner surface of the frame body 2 and the resin sheet bodies 3 and 3 are not pasted on both the front and back surfaces of the assembly 1. Since the outer peripheral edge portion 30 of the resin sheet 3 is slidably inserted into the insertion groove 19A of the L-shaped receiving member 19 and held in the insertion groove 19A, it is turned around an existing kumiko shoji (paper shoji). Even if there is no edge, it can be applied, and it is cheaper and can easily improve the heat insulation property, and it can cope with the expansion and contraction of the resin sheet bodies 3 and 3, and can be deformed and bent. Can be prevented.
