Description

本発明は、外装すだれに関する。   The present invention relates to exterior blinds.

ビル等の建物の外壁において、遮光用あるいは外観意匠のためにルーバーや、すだれを取り付けたものが知られている（例えば、特許文献１参照）。
特許文献１では、建物外周部に、上横枠、下横枠を配置し、上横枠及び下横枠に渡されるように縦向きに複数のルーバーが配置されている。各ルーバーは、所定の間隔を有して上横枠および下横枠の長手方向に並列状に配置されている。 In the outer wall of a building such as a building, one having a louver or a blind attached for shading or an appearance design is known (see, for example, Patent Document 1).
In Patent Document 1, an upper horizontal frame and a lower horizontal frame are arranged at the outer periphery of a building, and a plurality of louvers are arranged vertically so as to be passed over the upper horizontal frame and the lower horizontal frame. The louvers are arranged in parallel in the longitudinal direction of the upper horizontal frame and the lower horizontal frame with a predetermined interval.

特開２００８−８００５号公報JP 2008-8005 A

前記特許文献１では、ルーバーは、先細の略矩形である外側部材と、外側部材の室内側辺の左右端部から室内側に延在する片と、該片のそれぞれからさらに室内側に延在する片とを備えている。
このように、従来のルーバーは、ルーバー単体で剛性を確保できるように断面サイズを大型化しているため、ルーバーのデザインに制約があった。このため、断面サイズの小さな格子を用いた外装すだれが求められていた。 In the patent document 1, the louver extends from the left and right ends of the indoor side of the outer side member to the indoor side from the outer side member having a tapered substantially rectangular shape, and further to the indoor side from each of the pieces. And a piece to be
As described above, the conventional louver has a large cross-sectional size so that rigidity can be secured by the louver alone, so that the design of the louver is limited. For this reason, an exterior blind using a grid having a small cross-sectional size has been desired.

本発明の目的は、断面サイズの小さな格子を用いた外装すだれを提供することにある。   An object of the present invention is to provide an exterior blind using a grid of small cross-sectional size.

本発明の外装すだれは、建物の外壁の屋外側に配置される外装すだれであって、複数の格子が並設された第一格子列および第二格子列と、前記格子同士を連結する連結材とを備え、前記第二格子列は、前記第一格子列よりも屋外側に配置され、前記第一格子列および前記第二格子列の各格子は、並設方向に交互に配置され、前記連結材は、少なくとも前記第一格子列の格子と、前記第二格子列の格子とを連結することを特徴とする。 The exterior blind according to the present invention is an exterior blind arranged on the outdoor side of an outer wall of a building, and a connecting member for connecting the grids to a first grid row and a second grid row in which a plurality of grids are arranged in parallel. And the second grid row is disposed on the outdoor side relative to the first grid row, and the grids of the first grid row and the second grid row are alternately arranged in the parallel direction, The connecting member connects at least the grid of the first grid row and the grid of the second grid row.

本発明によれば、外装すだれが設置される壁面に沿った方向に、複数の格子を並設することで第一格子列を構成する。また、前記第一格子列よりも屋外側の位置に複数の格子を並設することで第二格子列を構成する。さらに、前記第一格子列および前記第二格子列の各格子は、並設方向（壁面に沿った方向）に交互に配置され、外装すだれを正面から見た際に、第一格子列の格子間に第二格子列の格子が配置され、第二格子列の格子間に第一格子列の格子が配置されるように設定している。そして、前記第一格子列の格子と、前記第二格子列の格子とを連結材で連結している。
このため、格子を壁面に沿った方向に一列に並設した場合に比べて、第一格子列および第二格子列の各格子が立体的に配置されるため、外装すだれの剛性を向上できる。したがって、各格子自体で剛性を高める必要性が低くなり、断面サイズの小さな格子を用いて外装すだれを構成できる。 According to the present invention, the first grid row is configured by arranging a plurality of grids in parallel in the direction along the wall surface where the exterior blinds are installed. Further, a plurality of lattices are arranged in parallel at a position on the outdoor side of the first lattice array to form a second lattice array. Furthermore, the grids of the first grid row and the second grid row are alternately arranged in the juxtaposed direction (the direction along the wall surface), and when the external blind is viewed from the front, the grids of the first grid row The grids of the second grid row are arranged between them, and the grids of the first grid row are set to be arranged between the grids of the second grid row. Then, the grid of the first grid row and the grid of the second grid row are connected by a connecting material.
For this reason, since the grids of the first grid row and the second grid row are three-dimensionally arranged as compared with the case where the grids are juxtaposed in a line in the direction along the wall surface, the rigidity of the outer sheath can be improved. Therefore, the need to increase the rigidity in each grid itself is reduced, and the outer blind can be configured using a grid having a small cross-sectional size.

本発明の外装すだれにおいて、前記格子は、３つの突出片を備えて断面形状が略Ｙ字状に形成され、前記連結材は、３つの連結片を備えて断面形状が略Ｙ字状に形成され、前記連結材の各連結片は、前記第一格子列の格子の突出片と、前記第二格子列の格子の突出片と、前記第一格子列または前記第二格子列のいずれか一方の格子の突出片とに、それぞれ連結されていることが好ましい。   In the sheathing blind of the present invention, the lattice includes three projecting pieces and a cross-sectional shape is formed in a substantially Y-shape, and the connecting member includes three connecting pieces and a cross-sectional shape is formed in a substantially Y-shape And each connecting piece of the connecting member is a protruding piece of the grid of the first grid row, a protruding piece of the grid of the second grid row, and either the first grid row or the second grid row Preferably, they are connected respectively to the projecting pieces of the grid.

格子および連結材がそれぞれ略Ｙ字状に形成されていれば、格子の断面形状と連結材の断面形状とが相似形となり、外装すだれの意匠性を向上できる。
また、各格子には３つの突出片が設けられているので、１つの格子に複数の連結材を連結することができる。連結材は３つの連結片を備えているので、３つの格子に連結することができる。
したがって、例えば第一格子列の隣り合う２つの格子と、第二格子列の１つの格子とを１つの連結材で連結し、この連結構造を各格子の並設方向に繰り返すことで、第一格子列および第二格子列を有する立体的な外装すだれを容易に構成できる。 If the grid and the connecting member are each formed in a substantially Y-shape, the cross-sectional shape of the grid and the cross-sectional shape of the connecting member become similar shapes, and the design of the exterior blind can be improved.
Further, since each projecting grid is provided with three projecting pieces, a plurality of connecting members can be connected to one grid. Since the connecting material comprises three connecting pieces, it can be connected to three grids.
Therefore, for example, two adjacent grids of the first grid row and one grid of the second grid row are connected by one connecting member, and the connection structure is repeated in the direction in which the grids are arranged in parallel. A three-dimensional armored blind having a grid row and a second grid row can be easily configured.

本発明の外装すだれにおいて、前記格子の各突出片は、突出寸法が互いに同一とされ、かつ、各突出片同士の交差角度が１２０度とされ、前記連結材の各連結片は、突出寸法が互いに同一とされ、かつ、各連結片同士の交差角度が１２０度とされていることが好ましい。   In the sheathing blind of the present invention, the projecting pieces of the grid have the same projecting dimension, and the crossing angle between the projecting pieces is 120 degrees, and each connecting piece of the connecting member has a projecting dimension of It is preferable that they be identical to each other, and that an intersection angle between the connection pieces be 120 degrees.

連結材の各連結片の突出寸法が互いに同一であり、かつ、連結片同士の交差角度が１２０度つまり等間隔とされているため、各連結片に連結される各格子を正三角形の頂点位置に配置することができる。このため、１本の格子に加わった荷重を、他の格子に均等に分散して伝達でき、外装すだれの剛性を向上できる。
また、前記格子の各突出片は、突出寸法が互いに同一とされ、かつ、各突出片同士の交差角度が１２０度とされているので、格子の１つの突出片に連結材などを介して力が伝達された際に、その力を他の２つの突出片に均等に分散して伝達できるため、格子自体の剛性も向上できる。
さらに、格子の各突出片と、連結材の各連結片とがそれぞれ１２０度間隔で突出されているので、格子の突出片と、連結材の連結片とを直線状に配置して連結することができ、連結構造をシンプルにできる。 Since the projecting dimensions of the connecting pieces of the connecting member are the same as each other and the crossing angles of the connecting pieces are 120 degrees, that is, equal intervals, each lattice connected to each connecting piece is at the vertex position of an equilateral triangle. Can be placed. For this reason, the load applied to one grid can be evenly distributed and transmitted to the other grids, and the rigidity of the outer blind can be improved.
Further, since each projecting piece of the grid has the same projecting dimension and the crossing angle of each projecting piece is 120 degrees, the force of one projecting piece of the grid through a connecting member etc. Since the force can be equally distributed to the other two projecting pieces when it is transmitted, the rigidity of the lattice itself can also be improved.
Furthermore, since each projecting piece of the grid and each connecting piece of the connecting member are projected at intervals of 120 degrees, the projecting piece of the grid and the connecting piece of the connecting member are linearly arranged and connected. Can make the connection structure simple.

本発明の外装すだれにおいて、前記格子の各突出片の先端には、前記突出片の幅寸法よりも大きな幅寸法とされた断面略円形の膨出部が形成され、前記連結材の各連結片には、前記突出片を挟んでカバーが固定され、前記各連結片およびカバーには、前記膨出部が嵌合する凹部と、前記突出片に当接する当接部とがそれぞれ設けられていることが好ましい。   In the sheathing blind of the present invention, a bulging portion having a substantially circular cross section, which is larger than the width of the projecting piece, is formed at the tip of each projecting piece of the grid, and each connecting piece of the connecting member The cover is fixed on both sides of the projecting piece, and the connection pieces and the cover are respectively provided with a recess in which the bulging portion is fitted and an abutting portion in contact with the projecting piece. Is preferred.

格子の突出片の先端に断面略円形の膨出部が形成されていれば、格子に対して風が吹き付けた際に、風切り音を低減できる。
また、連結片およびカバーで突出片を挟む際に、膨出部が各凹部に嵌合するため、突出片と連結片およびカバーとの接合強度を向上できる。 If a bulging portion having a substantially circular cross section is formed at the tip of the projecting piece of the grid, wind noise can be reduced when the wind is blown to the grid.
In addition, when the projecting piece is sandwiched between the connecting piece and the cover, the bulging portion is fitted in each recess, so that the bonding strength between the projecting piece and the connecting piece and the cover can be improved.

本発明の外装すだれにおいて、前記第一格子列と、前記第二格子列と、前記連結材と、前記第一格子列の各格子の並設方向に配置されて前記第一格子列の格子に連結されたユニット枠材とを備えたすだれユニットで構成されていることが好ましい。   In the sheathing blind of the present invention, the first grid row, the second grid row, the connecting member, and the grids of the first grid row are disposed in parallel to form the grids of the first grid row. It is preferable to be comprised by the interdigital unit provided with the unit frame material connected.

このように構成によれば、すだれユニットを工場で製造して建物の施工現場に輸送でき、施工現場では、建物の躯体側にすだれユニットを設置するだけでよいため、現場での施工作業を軽減できる。   According to this configuration, the blind unit can be manufactured at the factory and transported to the construction site of the building. At the construction site, it is only necessary to install the blind unit on the frame side of the building, so the construction work on the site is reduced. it can.

本発明の外装すだれにおいて、前記各格子の並設方向に複数の前記すだれユニットを配置して構成され、隣接する前記すだれユニット同士は第二連結材で連結され、前記第二連結材は、一方のすだれユニットの前記第一格子列の端部に配置された格子に連結される第１つなぎ材と、他方のすだれユニットの前記第一格子列の端部に配置された格子に連結される第２つなぎ材と、前記第１つなぎ材および前記第２つなぎ材に連結される第３つなぎ材とを備えて断面略Ｙ字状に形成され、前記第３つなぎ材には、各すだれユニットの前記第二格子列の端部の格子間に配置される格子が連結されていることが好ましい。   In the exterior blind of the present invention, a plurality of the plurality of the plurality of the plurality of said plurality of said plurality of said plurality of said plurality of said plurality of said plurality of said plurality of said plurality of said plurality are arranged A first binder connected to the grid disposed at the end of the first grid row of the interdigital unit, and a first tether connected to the grid disposed at the end of the first grid row of the other interdigital unit 2 cross-piece and a third cross-piece connected to the first and second cross-pieces to be formed into a substantially Y-shaped cross section, and the third cross-piece comprises Preferably, the grids arranged between the grids at the end of the second grid row are connected.

このような構成によれば、第二連結材は、第１つなぎ材、第２つなぎ材、第３つなぎ材の３つの部品で構成され、連結時には略Ｙ字状に形成される。また、第１，２つなぎ材は、第一格子列の格子に連結され、第３つなぎ材は第二格子列の格子間に配置される新たな格子に連結されるので、第一連結材による格子の連結構造と同等の見え方および強度を確保できる。したがって、複数のすだれユニットを連結した際に、連結部分が目立ちにくくなり、外装すだれの意匠の連続性を確保できる。   According to such a configuration, the second connecting member is configured by three parts of the first connecting member, the second connecting member, and the third connecting member, and is formed in a substantially Y shape at the time of connection. Also, since the first and second binders are connected to the grid of the first grid row and the third link is connected to a new grid arranged between the grids of the second grid row, The same appearance and strength as the lattice connection structure can be secured. Therefore, when connecting a plurality of blind units, the connecting portion becomes inconspicuous, and the continuity of the design of the external blind can be secured.

本発明によれば、断面サイズの小さな格子を用いて外装すだれを構成できる。   According to the present invention, the exterior blind can be configured using a lattice having a small cross-sectional size.

The upper ends of the upper frame holding portion 162 and the lower frame holding portion 163 have estimated dimensions (dimensions in the indoor and outdoor directions) in accordance with the groove widths of the engaging grooves 12 and 16 of the unit upper frame 11 and unit lower frame 15 described later. It is set.

［すだれユニット］
すだれユニット１０は、ユニット上枠１１と、ユニット下枠１５と、縦格子２０と、連結材３０，４０，５０とを備えて構成されている。
ユニット上枠１１およびユニット下枠１５は、アルミ押出形材で構成され、ユニット支持材６と同じ長さ寸法とされている。
ユニット上枠１１は、上枠保持部１６２に係合する係合溝１２と、格子ブラケット６０が固定される固定部１３とを備えて構成されている。
ユニット下枠１５は、下枠保持部１６３に係合する係合溝１６と、格子ブラケット６０が固定される固定部１７とを備えて構成されている。 [Snow unit]
The interdigital unit 10 includes a unit upper frame 11, a unit lower frame 15, a vertical lattice 20, and connecting members 30, 40, and 50.
The unit upper frame 11 and the unit lower frame 15 are made of an extruded aluminum material, and have the same length as the unit support 6.
The unit upper frame 11 is configured to include an engagement groove 12 engaged with the upper frame holding portion 162 and a fixing portion 13 to which the lattice bracket 60 is fixed.
The unit lower frame 15 is configured to include an engagement groove 16 engaged with the lower frame holding portion 163 and a fixing portion 17 to which the lattice bracket 60 is fixed.

すだれユニット１０は、カーテンウォールと同様に、ユニット上枠１１が上枠保持部１６２に係合することで吊り下げられて支持されている。また、ユニット下枠１５が下枠保持部１６３に係合することで、すだれユニット１０の屋内外方向の移動（揺れ）を規制している。
また、図示を省略するが、上枠保持部１６２の左右方向の中心位置には、ユニット上枠１１の上面を押さえる上がり止め用の押さえ部材がネジ止めされている。この押さえ部材は、アルミ押出形材製のアングル材等で構成され、すだれユニット１０が風圧などで上方に移動することを規制する。
さらに、図示を省略するが、下枠保持部１６３の左右方向の中心位置には、ユニット下枠１５の屋内面に当接する振れ止め用の押圧部材が取り付けられている。この押圧部材は、アルミ角棒等で構成され、固定板部１６１にネジ止めされたボルト等でユニット下枠１５を下枠保持部１６３に押し付け、ユニット下枠１５つまりすだれユニット１０が屋内外方向に振れることを規制する。
また、図３に示すように、ユニット支持材６の一端近傍には、ユニット上枠１１、ユニット下枠１５のそれぞれに嵌合する面内固定材８がネジ止めされている。この面内固定材８は、アルミ押出形材からなるチャンネル材等で構成され、上枠保持部１６２、下枠保持部１６３にそれぞれ配置されている。ユニット上枠１１およびユニット下枠１５には、面内固定材８が嵌合する切欠が形成されており、この切欠に面内固定材８が嵌合することで、ユニット上枠１１およびユニット下枠１５が面内方向つまりユニット支持材６の長手方向に移動することが規制されている。 Like the curtain wall, the interdigital unit 10 is suspended and supported by the unit upper frame 11 engaging with the upper frame holding portion 162. In addition, the unit lower frame 15 engages with the lower frame holding portion 163 to restrict movement (swing) in the indoor / outdoor direction of the interdigital unit 10.
Further, although not shown, at the central position in the left-right direction of the upper frame holding portion 162, a pressing member for preventing rising is pressed by screwing the upper surface of the unit upper frame 11. The pressing member is formed of an angle member or the like made of an extruded aluminum material, and restricts the upward movement of the blind unit 10 by wind pressure or the like.
Furthermore, although illustration is omitted, at the center position of the lower frame holding portion 163 in the left-right direction, a pressing member for anti-vibration that contacts the indoor surface of the unit lower frame 15 is attached. The pressing member is formed of an aluminum square rod or the like, and the unit lower frame 15 is pressed against the lower frame holding portion 163 by a bolt or the like screwed to the fixing plate portion 161, and the unit lower frame 15 or Regulate to shake.
Further, as shown in FIG. 3, an in-plane fixing material 8 fitted to each of the unit upper frame 11 and the unit lower frame 15 is screwed in the vicinity of one end of the unit support 6. The in-plane fixing material 8 is made of a channel material or the like made of an extruded aluminum material, and is disposed in the upper frame holding portion 162 and the lower frame holding portion 163, respectively. The unit upper frame 11 and the unit lower frame 15 are formed with a notch in which the in-plane fixing material 8 is fitted, and the in-plane fixing material 8 is fitted in the notch to form the unit upper frame 11 and the unit lower The movement of the frame 15 in the in-plane direction, that is, in the longitudinal direction of the unit support 6 is restricted.

ユニット下枠１５の係合溝１６の高さ寸法は、ユニット上枠１１の係合溝１２の高さ寸法よりも大きく設定されている。このため、ユニット上枠１１およびユニット下枠１５間の高さ寸法や、上下に配置されるユニット支持材６間の高さ寸法に誤差があっても、係合溝１６と下枠保持部１６３とを確実に係合できる。   The height dimension of the engagement groove 16 of the unit lower frame 15 is set larger than the height dimension of the engagement groove 12 of the unit upper frame 11. Therefore, even if there is an error in the height dimension between the unit upper frame 11 and the unit lower frame 15 or the height dimension between the unit support members 6 arranged vertically, the engagement groove 16 and the lower frame holding portion 163 Can be reliably engaged.

ユニット上枠１１およびユニット下枠１５は、すだれユニット１０の上端近傍および下端近傍に配置されている。具体的には、上下階の各庇２に取り付けられたユニット支持材６のうち、下階のユニット支持材６の下枠保持部１６３に係合可能な高さ位置にユニット下枠１５が配置され、上階のユニット支持材６の上枠保持部１６２に係合可能な高さ位置にユニット上枠１１が配置されている。   The unit upper frame 11 and the unit lower frame 15 are disposed near the upper end and the lower end of the interdigital unit 10. Specifically, the unit lower frame 15 is disposed at a height position that can be engaged with the lower frame holding portion 163 of the lower unit support member 6 among the unit support members 6 attached to the respective ridges 2 of the upper and lower floors. The unit upper frame 11 is disposed at a height position that can be engaged with the upper frame holding portion 162 of the unit support member 6 on the upper floor.

［縦格子の構成］
縦格子２０は、上下方向に沿って配置され、前記ユニット上枠１１およびユニット下枠１５に掛け渡される長さ寸法に形成されている。
各縦格子２０は、図４、５にも示すように、断面形状が略Ｙ字状に形成されたアルミ押出形材で構成されている。すなわち、縦格子２０は、断面中心位置から３方向に突出された突出片２１，２２，２３を備えている。各突出片２１，２２，２３同士の交差角度は１２０度とされている。すなわち、突出片２１，２２，２３は、各突出片２１，２２，２３が互いに連続する部分である縦格子２０の断面中心に対して、１２０度間隔で突出されている。
各突出片２１，２２，２３の先端には、断面略円形の膨出部２１Ａ，２２Ａ，２３Ａが形成されている。膨出部２１Ａ，２２Ａ，２３Ａは、突出片２１，２２，２３の幅寸法よりも大きな幅寸法とされている。
縦格子２０の長手寸法（上下方向の寸法）は、建物の各階の高さ寸法、つまり建物の上下に複数設けられた庇２の上下間隔に応じた長さ寸法とされている。 [Vertical grid configuration]
The vertical grid 20 is disposed along the vertical direction, and is formed to have a length dimension to be spanned by the unit upper frame 11 and the unit lower frame 15.
Each vertical grid 20 is, as shown in FIGS. 4 and 5, formed of an extruded aluminum material having a substantially Y-shaped cross section. That is, the vertical grid 20 is provided with the projecting pieces 21, 22 and 23 which are protruded in three directions from the cross-sectional center position. The crossing angle between the projecting pieces 21, 22, 23 is 120 degrees. That is, the projecting pieces 21, 22, 23 project at intervals of 120 degrees with respect to the cross-sectional center of the vertical grid 20 in which the projecting pieces 21, 22, 23 are continuous with each other.
Bulges 21A, 22A, and 23A having a substantially circular cross section are formed at the ends of the projecting pieces 21, 22, and 23, respectively. The bulging portions 21A, 22A, and 23A have a width that is greater than the width of the protruding pieces 21, 22, and 23.
The longitudinal dimension (dimension in the vertical direction) of the vertical lattice 20 is a height dimension corresponding to the height dimension of each floor of the building, that is, the vertical interval of the plurality of weirs 2 provided above and below the building.

すだれユニット１０において、縦格子２０は、ユニット上枠１１、ユニット下枠１５に沿って配置されて第一格子列１０Ａを構成する縦格子２０Ａと、第一格子列１０Ａの屋外側に沿って配置されて第二格子列１０Ｂを構成する縦格子２０Ｂとを備えている。縦格子２０Ａおよび縦格子２０Ｂは、同一断面形状、同一寸法の格子２０であり、すだれユニット１０における配置位置のみが異なるものである。
第一格子列１０Ａに配置される縦格子２０Ａの配置間隔と、第二格子列１０Ｂに配置される縦格子２０Ｂの配置間隔とは同じ間隔とされている。また、第一格子列１０Ａに配置される各縦格子２０Ａの左右方向の配置位置は、第二格子列１０Ｂに配置される各縦格子２０Ｂ間の中心位置とされている。すなわち、縦格子２０Ａと縦格子２０Ｂとは、格子２０の並設方向、つまり壁面に沿った方向に交互に配置されている。
第一格子列１０Ａと第二格子列１０Ｂとの間隔は、第一格子列１０Ａおよび第二格子列１０Ｂで、左右方向および屋内外方向で互いに隣り合う３つの縦格子２０の断面中心位置を結ぶ線が略正三角形となるように設定されている。
また、各縦格子２０は、突出片２１が屋内側に向き、突出片２２、２３が屋外側の左右斜め方向、つまり屋外方向に対して６０度傾斜する方向に向くように配置されている。 In the interdigital unit 10, the vertical grids 20 are arranged along the unit upper frame 11 and the unit lower frame 15 to constitute the first grid row 10A, and are arranged along the outdoor side of the first grid row 10A. And a vertical grid 20B that constitutes a second grid row 10B. The vertical grids 20A and the vertical grids 20B are grids 20 having the same cross-sectional shape and the same size, and differ only in the arrangement position in the interdigital unit 10.
The arrangement interval of the vertical lattices 20A arranged in the first lattice array 10A and the arrangement interval of the vertical lattices 20B arranged in the second lattice array 10B are the same. In addition, the arrangement position of the vertical lattices 20A arranged in the first lattice row 10A in the left-right direction is taken as the central position between the vertical lattices 20B arranged in the second lattice row 10B. That is, the vertical grids 20A and the vertical grids 20B are alternately arranged in the parallel direction of the grids 20, that is, in the direction along the wall surface.
The distance between the first grid row 10A and the second grid row 10B is the first grid row 10A and the second grid row 10B connecting the cross-sectional center positions of three vertical grids 20 adjacent to each other in the left-right direction and indoor / outdoor direction The lines are set to be substantially equilateral triangles.
The vertical grids 20 are arranged such that the projecting pieces 21 face the indoor side and the projecting pieces 22 and 23 face the left and right diagonal directions on the outdoor side, that is, in the direction inclined 60 degrees with respect to the outdoor direction.

［連結材の構成］
縦格子２０を連結する連結材として、第一連結材３０と、他のすだれユニット１０との連結部用の第二連結材４０と、すだれユニット１０の端部用の第三連結材５０との３種類の連結材が用いられている。 [Composition of connecting material]
The first connecting member 30, the second connecting member 40 for the connecting portion with the other blind unit 10, and the third connecting member 50 for the end of the blind unit 10 are used as a connecting member for connecting the vertical grid 20. Three types of connecting materials are used.

［第一連結材の構成］
第一連結材３０は、図４および図６にも示すように、第一格子列１０Ａの隣り合う２つの縦格子２０Ａと、第二格子列１０Ｂにおいて左右方向の位置が前記２つの縦格子２０Ａ間に配置される縦格子２０Ｂとを連結する連結材である。
第一連結材３０は、断面形状が略Ｙ字状に形成されたアルミ押出形材で構成されている。すなわち、第一連結材３０は、断面中心位置から３方向に突出された連結片３１，３２，３３を備えている。各連結片３１，３２，３３同士の交差角度は１２０度とされている。すなわち、連結片３１，３２，３３は、第一連結材３０の断面中心に対して１２０度間隔で突出されている。
なお、第一連結材３０および後述する第二連結材４０、第三連結材５０は、縦格子２０に比べて短尺のピース材とされており、図１に示すように、縦格子２０の長手方向（上下方向）に沿った複数箇所で、縦格子２０に連結されている。 [Configuration of first connecting material]
As shown also in FIGS. 4 and 6, the first connecting member 30 has two vertical grids 20A adjacent to each other in the first grid row 10A, and the two vertical grids 20A in the second grid row 10B in the left-right direction. It is a connecting material which connects with the vertical lattice 20B arranged between.
The first connecting member 30 is made of an extruded aluminum material having a substantially Y-shaped cross section. That is, the first connection member 30 includes the connection pieces 31, 32, and 33 protruding in three directions from the cross-sectional center position. The crossing angle of each of the connection pieces 31, 32, and 33 is 120 degrees. That is, the connection pieces 31, 32, 33 protrude at an interval of 120 degrees with respect to the cross-sectional center of the first connection member 30.
The first connecting member 30, and the second connecting member 40 and the third connecting member 50, which will be described later, are piece members shorter than the vertical lattice 20, and as shown in FIG. The vertical grid 20 is connected to a plurality of locations along the direction (vertical direction).

第一連結材３０の連結片３１，３２，３３の先端には、挟持部３１１，３２１，３３１が形成されている。挟持部３１１，３２１，３３１にはカバー３５がリベット３６で固定され、挟持部３１１，３２１，３３１およびカバー３５で縦格子２０の突出片２１，２２，２３を挟持している。
挟持部３１１，３２１，３３１は、カバー３５との間に挟まれる縦格子２０の突出片２１，２２，２３が連結片３１，３２，３３の厚さ方向の中心となるように片側にずれて形成されている。この際、第一格子列１０Ａに配置される縦格子２０の突出片２２，２３を挟む挟持部３１１，３２１は、ユニット上枠１１、ユニット下枠１５側、つまりすだれユニット１０の裏面側にずれて形成されている。このため、挟持部３１１，３２１に固定されるカバー３５は、すだれユニット１０の表面側に配置される。挟持部３１１，３２１にカバー３５をリベット３６で固定する際に、すだれユニット１０の表面側から治具を用いてカシメ作業を行うことができる。 Clamping portions 311, 321, 331 are formed at the tips of the connecting pieces 31, 32, 33 of the first connecting member 30. A cover 35 is fixed to the sandwiching portions 311, 321, 331 by rivets 36, and the projecting portions 21, 22, 23 of the vertical grid 20 are clamped by the sandwiching portions 311, 321, 331 and the cover 35.
The holding portions 311, 321, 331 are shifted to one side so that the protruding pieces 21, 22, 23 of the vertical grid 20, which are sandwiched with the cover 35, are the centers in the thickness direction of the connecting pieces 31, 32, 33. It is formed. At this time, the sandwiching portions 311 and 321 sandwiching the projecting pieces 22 and 23 of the vertical grid 20 arranged in the first grid row 10A are shifted to the unit upper frame 11 and the unit lower frame 15 side, that is, the back surface side of the interdigital unit 10 It is formed. For this reason, the cover 35 fixed to the holding parts 311 and 321 is disposed on the front surface side of the interdigital unit 10. When the cover 35 is fixed to the holding portions 311 and 321 with the rivets 36, a caulking operation can be performed using a jig from the surface side of the interdigital unit 10.

挟持部３１１，３２１，３３１およびカバー３５は、縦格子２０の膨出部２１Ａ，２２Ａ，２３Ａが配置される凹部と、突出片２１，２２，２３に当接する当接部とを備えており、前記リベット３６は当接部を貫通して固定されている。前記リベット３６は、図４に示すように、第一連結材３０の各挟持部３１１〜３３１およびカバー３５において、上下方向に２本以上設けられて固定されている。すなわち、挟持部３１１，３２１，３３１およびカバー３５の各当接部には、上下方向に離れて複数の接合穴が形成され、前記突出片２１，２２，２３にも上下方向に離れて複数の接合穴が形成されている。
１つの突出片２１、２２，２３において、それぞれ複数本のリベット３６で固定しており、リベット３６が挿通される接合穴も長穴ではなく、リベット３６の軸に合わせた寸法とされている。このため、縦格子２０と、第一連結材３０およびカバー３５との接合は、いわゆる剛接合と見なすことができる。後述する第二連結材４０や第三連結材５０におけるリベット３６の接合部分も、同様に剛接合と見なすことができる。 The holding portions 311, 321, 331 and the cover 35 are provided with concave portions in which the bulging portions 21A, 22A, 23A of the vertical lattice 20 are disposed, and contact portions in contact with the projecting pieces 21, 22, 23. The rivets 36 are fixed through the abutments. As shown in FIG. 4, two or more rivets 36 are provided and fixed in the vertical direction in each of the holding portions 311 to 331 and the cover 35 of the first connecting member 30. That is, a plurality of bonding holes are formed in the contact portions of the sandwiching portions 311, 321, 331 and the cover 35 so as to be vertically separated from each other, and the plurality of projecting pieces 21, 22, 23 are also vertically separated from each other. Junction holes are formed.
A plurality of rivets 36 are used to fix one projecting piece 21, 22, 23, respectively, and the joint holes into which the rivets 36 are inserted are also sized not to be long holes but to the axes of the rivets 36. Therefore, the connection between the vertical grid 20 and the first connecting member 30 and the cover 35 can be regarded as a so-called rigid connection. The joint portions of the rivets 36 in the second connecting member 40 and the third connecting member 50 to be described later can also be regarded as rigid connections.

挟持部３１１，３２１，３３１およびカバー３５で縦格子２０の突出片２１，２２，２３を挟んだ際に、膨出部２１Ａ，２２Ａ，２３Ａが凹部に嵌合する。このため、挟持部３１１，３２１，３３１およびカバー３５間に挟持された縦格子２０に、突出片２１，２２，２３を引き抜く方向の力が加わっても、前記リベット３６による接合に加えて、膨出部２１Ａ，２２Ａ，２３Ａが凹部に嵌合しているので、前記引き抜く方向の力に耐えることができ、接合強度を向上できる。   When the protruding pieces 21, 22, 23 of the vertical lattice 20 are sandwiched by the holding parts 311, 321, 331 and the cover 35, the bulging parts 21A, 22A, 23A fit in the concave parts. For this reason, even if a force is applied to the vertical grid 20 held between the holding portions 311, 321, 331 and the cover 35 in the direction in which the protruding pieces 21, 22, 23 are pulled out, Since the protrusions 21A, 22A, and 23A are fitted in the recesses, the force in the pulling direction can be resisted, and the bonding strength can be improved.

［第二連結材の構成］
第二連結材４０は、図５および図７に示すように、隣接する２つのすだれユニット１０において、各すだれユニット１０の第一格子列１０Ａの端部に配置された縦格子２０Ａに連結される第１つなぎ材４１、第２つなぎ材４２と、各つなぎ材４１，４２間に挟まれて連結される第３つなぎ材４３との３つの部材で構成されている。
ここで、各つなぎ材４１，４２は、同一形状の部品であり、向きを変えて配置されている。各つなぎ材４１，４２は、連結片４１０，４２０と、連結片４１０，４２０に対して１２０度の交差角度で連続する連結部４１５，４２５とを備えている。連結片４１０，４２０の先端には、縦格子２０の突出片２３、突出片２２をカバー３５とで挟持する挟持部４１１，４２１が形成されている。
第３つなぎ材４３は、つなぎ材４１，４２の連結部４１５、４２５間に挟持されてリベット３６で固定される基端部４３０と、各すだれユニット１０の縦格子２０Ｂ間に配置される縦格子２０の突出片２１をカバー３５とで挟持する挟持部４３１とを備えている。
前記挟持部４１１，４２１，４３１は、前記挟持部３１１，３２１，３３１と同様の構成であるため、説明を省略する。 [Configuration of second connecting material]

For this reason, it is possible to three-dimensionally arrange the vertical grids 20 to improve the rigidity of the outer blind 1, and it is not necessary to increase the cross-sectional size of the vertical grid 20 itself to secure the rigidity. Can be configured.

縦格子２０および第一連結材３０がそれぞれ略Ｙ字状に形成されているので、縦格子２０および第一連結材３０の断面形状が相似形となり、統一感を与えることができるので、外装すだれ１の意匠性を向上できる。
縦格子２０に３つの突出片２１〜２３を設けたので、縦格子２０Ａには、２つの第一連結材３０と、格子ブラケット６０とを連結できる。また、第一連結材３０に３つの連結片３１〜３３を設けたので、第一連結材３０には３つの縦格子２０を連結できる。このため、縦格子２０Ａにユニット上枠１１、ユニット下枠１５を連結でき、かつ、２つの第一連結材３０を用いて左右に配置された他の縦格子２０Ａおよび縦格子２０Ｂとも連結できる。したがって、この連結構造を縦格子２０の並設方向に繰り返して各縦格子２０を連結することで、第一格子列１０Ａおよび第二格子列１０Ｂを有する立体的な外装すだれ１を容易に構成できる。 Since the vertical grid 20 and the first connecting member 30 are each formed in a substantially Y-shape, the cross-sectional shapes of the vertical grid 20 and the first connecting member 30 have a similar shape and can give a feeling of unity. The designability of 1 can be improved.
Since the three projecting pieces 21 to 23 are provided on the vertical grid 20, the two first connecting members 30 and the grid bracket 60 can be connected to the vertical grid 20A. In addition, since the three connection pieces 31 to 33 are provided on the first connection member 30, the three vertical grids 20 can be connected to the first connection member 30. Therefore, the unit upper frame 11 and the unit lower frame 15 can be connected to the vertical grid 20A, and can also be connected to other vertical grids 20A and 20B arranged on the left and right using the two first connecting members 30. Therefore, by repeating this connection structure in the direction in which the vertical grids 20 are arranged, and connecting the vertical grids 20, it is possible to easily construct the three-dimensional sheathed blind 1 having the first grid row 10A and the second grid row 10B. .

さらに、第二連結材４０および第三連結材５０は、第一連結材３０と同様の見え方や強度を確保できるように構成したので、すだれユニット１０の接合部や外装すだれ１の端部においても統一したデザインにでき、意匠性も向上できる。   Furthermore, since the second connecting member 40 and the third connecting member 50 are configured to ensure the same appearance and strength as the first connecting member 30, the joint portion of the interdigital unit 10 and the end portion of the exterior blind 1 are prepared. The design can be unified as well, and the design can be improved.

第一連結材３０の各連結片３１〜３３の突出寸法が互いに同一であり、かつ、連結片３１〜３３同士の交差角度が１２０度つまり等間隔とされているため、各連結片３１〜３３に連結される縦格子２０を正三角形の頂点位置に配置することができる。このため、１本の縦格子２０に加わった荷重を、他の縦格子２０に均等に分散して伝達でき、外装すだれ１の剛性を向上できる。
その上、壁面の左右方向において、縦格子２０Ａの中間位置に縦格子２０Ｂを配置しているので、太陽の向きにかかわらず、日差しを遮る遮光性能をある程度確保できる。また、外部からの視線を程よく遮断でき、内部からの見通しもある程度確保できる。 The projection dimensions of the connection pieces 31 to 33 of the first connection member 30 are the same as each other, and the crossing angles of the connection pieces 31 to 33 are 120 degrees, that is, equal intervals. A vertical grid 20 connected to can be placed at the vertex position of an equilateral triangle. For this reason, the load applied to one vertical grid 20 can be equally distributed to the other vertical grids 20 and transmitted, and the rigidity of the exterior blind 1 can be improved.
In addition, since the vertical grid 20B is disposed at the middle position of the vertical grid 20A in the left-right direction of the wall surface, the light shielding performance for blocking the sunlight can be secured to some extent regardless of the direction of the sun. In addition, the line of sight from the outside can be cut off moderately, and the prospect from inside can be secured to some extent.

縦格子２０の各突出片２１〜２３は、突出寸法が互いに同一とされ、かつ、各突出片２１〜２３同士の交差角度が１２０度とされているので、縦格子２０の１つの突出片２１〜２３に連結材３０などを介して力が伝達された際に、その力を他の２つの突出片２１〜２３に均等に分散して伝達できるため、縦格子２０自体の剛性も向上できる。
縦格子２０の各突出片２１〜２３と、第一連結材３０の各連結片３１〜３３とがそれぞれ１２０度間隔で突出されているので、縦格子２０の突出片２１〜２３と、第一連結材３０の連結片３１〜３３とを直線状に配置して連結することができる。このため、挟持部３１１，３２１，３３１およびカバー３５で突出片２１〜２３を挟持するシンプルな連結構造を採用でき、接合作業性も向上できる。 The projecting pieces 21 to 23 of the longitudinal grid 20 have the same projecting dimension, and the crossing angle between the projecting pieces 21 to 23 is 120 degrees, so one projecting piece 21 of the longitudinal grid 20 When a force is transmitted to 2323 via the connecting member 30 etc., the force can be equally distributed to the other two projecting pieces 21 to 23 and transmitted, so that the rigidity of the vertical lattice 20 itself can also be improved.
Since the respective projecting pieces 21 to 23 of the vertical grid 20 and the connecting pieces 31 to 33 of the first connecting member 30 are projected at intervals of 120 degrees, the projecting pieces 21 to 23 of the vertical grid 20, and the first The connection pieces 31 to 33 of the connection member 30 can be linearly arranged and connected. For this reason, the simple connection structure which clamps the protrusion pieces 21-23 by the clamping parts 311, 321, 331 and the cover 35 can be employ | adopted, and joining workability can also be improved.

縦格子２０の各突出片２１〜２３の先端に断面略円形の膨出部２１Ａ，２２Ａ，２３Ａを形成したので、縦格子２０に対して風が吹き付けた際に、風切り音を低減できる。
また、連結片３１〜３３およびカバー３５で突出片２１〜２３を挟む際に、膨出部２１Ａ，２２Ａ，２３Ａが各凹部に嵌合するため、突出片２１〜２３と連結片３１〜３３およびカバー３５との接合強度を向上できる。 Since the bulging portions 21A, 22A, 23A having a substantially circular cross section are formed at the tips of the projecting pieces 21 to 23 of the vertical lattice 20, wind noise can be reduced when the wind is blown to the vertical lattice 20.
In addition, when the protruding pieces 21 to 23 are sandwiched by the connecting pieces 31 to 33 and the cover 35, the protruding portions 21A, 22A, and 23A fit into the respective recesses, so the protruding pieces 21 to 23 and the connecting pieces 31 to 33 and The bonding strength with the cover 35 can be improved.

外装すだれ１を、すだれユニット１０を並設して構成しているので、現場での施工作業を軽減できる。また、すだれユニット１０は、第一格子列１０Ａ、第二格子列１０Ｂ、第一連結材３０を備えて立体的に構成されるので、すだれユニット１０を輸送する際にも剛性を確保でき、容易に取り扱うことができる。   Since the exterior blind 1 is constructed by arranging the blind units 10 in parallel, the construction work on the site can be reduced. Further, since the interdigital unit 10 is three-dimensionally configured including the first lattice array 10A, the second lattice array 10B, and the first connecting member 30, rigidity can be ensured even when transporting the interdigital unit 10, which is easy It can be handled by

第二連結材４０を、第１つなぎ材４１、第２つなぎ材４２、第３つなぎ材４３の３つの部品で構成し、連結時には略Ｙ字状に構成できるようにしているので、すだれユニット１０の連結部分も第一連結材３０を用いた接合構造と同様の構成にできる。また、第１つなぎ材４１、第２つなぎ材４２は、同一の部品で構成できるので、コストを低減できる。
さらに、第１つなぎ材４１および第２つなぎ材４２を予めすだれユニット１０に取り付けてから、すだれユニット１０を設置することができ、すだれユニット１０の設置後は、第３つなぎ材４３を第１つなぎ材４１、第２つなぎ材４２間に差し込んでリベット３６で固定する作業のみを行えばよいので、現場での施工作業性を向上できる。 The second connecting member 40 is constituted by three parts of the first connecting member 41, the second connecting member 42, and the third connecting member 43, and can be configured in a substantially Y-shape at the time of connection. The connecting portion of the above can also be configured in the same manner as the joint structure using the first connecting member 30. Further, since the first connecting member 41 and the second connecting member 42 can be formed of the same parts, the cost can be reduced.
Furthermore, after the first connecting member 41 and the second connecting member 42 are attached to the interdigital unit 10 in advance, the interdigital unit 10 can be installed, and after the installation of the interdigital unit 10, the third connecting member 43 is used as the first junction Since only the work of inserting between the material 41 and the second connecting material 42 and fixing with the rivet 36 may be performed, the construction workability at the site can be improved.

第三連結材５０も、２つの縦格子２０Ｂと、１つの縦格子２０Ａとを連結している２つの第一連結材３０と重なる形状に構成しているので、すだれユニット１０の端部も第一連結材３０を用いた接合構造と同様の構成にできる。
第三連結材５０は、外装すだれ１の端部に配置されるすだれユニット１０に予め取り付けることができるので、すだれユニット１０を壁面に設置後に第三連結材５０を取り付ける必要が無く、現場での施工作業性を向上できる。 Since the third connecting member 50 is also configured to overlap the two first connecting members 30 connecting the two vertical grids 20B and one vertical grid 20A, the end of the interdigital unit 10 is also A structure similar to that of a bonded structure using one connecting member 30 can be made.
Since the third connecting member 50 can be attached in advance to the blind unit 10 disposed at the end of the exterior blind 1, there is no need to attach the third connecting member 50 after the blind unit 10 is installed on the wall surface. Construction workability can be improved.
