Description

  The present invention relates to a heat insulating lighting fixture that covers an opening of a building and performs heat insulation indoors and outdoors and daylighting from the outdoor side.

  Various functions are required for joinery covering an opening of a building in order to maintain a comfortable indoor environment. First, it is required to secure lighting while covering indoors and outdoors with joinery so that visibility from the outdoor side is reduced for privacy protection.

  Moreover, in winter, heat on the indoor side is easily dissipated to the outdoor side through the fittings, which is a major factor for reducing the indoor heating efficiency. Accordingly, the joinery is also required to have high heat insulation itself.

  As one of the fittings that satisfy these requirements, Patent Document 1 describes a double window for indoor use. This double window has two thin surface plates (sheet materials) made of synthetic resin. Since each surface board is transparent or semi-transparent, it is possible to ensure daylighting from the outdoor side while covering the opening of the building.

  In addition, a rib (separator) that connects the two surface plates is provided. This rib can be of various shapes, and a grid-like rib formed by crossing ones extending in different directions has been proposed. The transparent or translucent surface plate itself cannot be expected to have a function of reducing visibility from the outside. However, by providing this lattice-shaped rib between the two surface plates, the light from the outdoor side passes through the inside of the lattice, and the visibility from the outdoor side is reduced without significantly impairing the lighting performance. Can do.

  Further, the rib divides the two surface plates into a plurality of spaces. Since air exists in each of the partitioned spaces, heat transfer from the indoor side to the outdoor side is performed via this air. In Patent Document 1, it is said that the heat transfer is slowed by the air, and the heat insulation of the entire double window can be improved.

  However, if a single double window is configured by two surface plates and ribs having a lattice shape sandwiched between the two surface plates as in the double window described in Patent Document 1, a great deal of labor is required for molding. It was.

  That is, when the ribs are in a lattice shape, the ribs extend in a plurality of directions between the two surface plates, so that it is difficult to integrally form the two surface plates and the ribs by extrusion molding. Therefore, it is necessary to provide a grid-like rib that has been molded separately from the surface plate by bonding or welding between the two surface plates. Therefore, the manufacturing cost of the joinery itself has been increased.

  The present invention has been made in view of such a problem, and an object thereof is to provide a heat insulating lighting fixture which is excellent in heat insulating properties and daylighting properties and can protect privacy while suppressing manufacturing costs. There is to do.

  In order to solve the above problems, a heat insulating daylighting fixture according to the present invention is a heat insulating daylighting fixture that covers an opening of a building and performs heat insulation indoors and outdoors and daylighting outdoors. A face material covering the opening with the other side facing the outdoor side and a frame material that sandwiches a peripheral edge of the face material in the thickness direction, the face material having a plurality of translucency The plurality of panels are configured to overlap each other in the thickness direction, and the plurality of panels include a plurality of facing surface plates and a plurality of the surface plates connected to each other and extending in a direction perpendicular to the thickness direction. Each of the two adjacent panels along the thickness direction, the extending direction of the ribs in the front panel and the extension of the ribs in the rear panel. So that the current direction intersects each other It is characterized by being location.

  In the heat insulating lighting fixture according to the present invention, when two adjacent panels are viewed along the thickness direction, the extending direction of the ribs on the near side panel and the extending direction of the ribs on the far side panel are: Arranged to cross each other. In other words, when the rib of the near panel and the rib of the far panel are projected in the thickness direction, they are arranged so as to overlap and intersect. Therefore, when viewed along the thickness direction of the face material, it seems that a lattice is formed inside the face material due to the intersection of the extending directions of the ribs. This makes it possible to protect privacy by reducing visibility from the outdoor side while securing daylighting.

  As described above, since the extending directions of the ribs of the plurality of panels intersect each other visually to form a lattice shape, the extending direction of the ribs in each panel may be one direction. Therefore, each panel can be integrally formed by extrusion molding of two surface plates and a plurality of ribs. Since many panels that are extrusion molded in this way are inexpensive and versatile, it is possible to construct a face material using this general-purpose panel, thereby reducing manufacturing costs. be able to.

  Further, each of the plurality of panels is partitioned into a plurality of spaces by ribs between the two surface plates. Therefore, a plurality of panels are overlapped to form a face material, and a plurality of surface plates are provided as a boundary surface between the indoor side and the outdoor side, so that the heat insulation is improved and the ribs are partitioned. It is possible to improve the heat insulating property by utilizing the air present in each formed space.

  Moreover, in the heat insulating lighting fixture according to the present invention, the face material includes an indoor side panel that forms the one side surface of the face material, an outdoor side panel that forms the other side surface of the face material, the indoor side panel, and And at least three of the inner panels arranged between the outdoor side panels, and the indoor side panel and the outdoor side panel both have the rib extending in the longitudinal direction of the face material. The inner panel has an extension direction of the ribs of the indoor side panel and the outdoor side panel when viewed along the thickness direction. It is also preferable to arrange so as to intersect with the present direction.

  From the viewpoint of ensuring the rigidity of the panel itself constituting the face material, it is desirable that the ribs between the two surface plates extend in the longitudinal direction of the panel. Most of the above-mentioned general-purpose panel ribs on the market adopt the same configuration.

  Therefore, in this preferred embodiment, both the indoor side panel and the outdoor side panel are arranged such that the extending direction of the ribs is substantially the same as the longitudinal direction of the face material. Thereby, when comprising an indoor side panel and an outdoor side panel using the said general purpose panel, the longitudinal direction is made to correspond with the longitudinal direction of a face material, and each of an indoor side panel and an outdoor side panel is made into one general purpose. It is easy to configure with panels. In other words, it is not necessary to configure each of the indoor side panel and the outdoor side panel by connecting a plurality of general-purpose panels. Accordingly, it is easy to seamlessly form the indoor side panel that forms one side surface in the thickness direction of the face material and the outdoor side panel that forms the other side surface.

  Moreover, the internal panel arrange | positioned between an indoor side panel and an outdoor side panel, when it sees along the thickness direction of a face material, the extension direction of the rib is each rib of an indoor side panel and an outdoor side panel It is arranged so as to intersect the extending direction of About this internal panel, even when it comprises and connects several general purpose panels, since those joints are covered with an indoor side panel and an outdoor side panel, they do not stand out from the outside.

  That is, according to this preferred embodiment, there is no joint of the panel, or even if there is a joint of the panel, it is inconspicuous and has high designability, but visually forms a lattice by the overlap of the ribs, It is possible to improve heat insulation and reduce visibility.

The opening OP is provided with a frame 19 along the periphery thereof. A window sash and a screen door (not shown) are provided on the outdoor side of the frame 19, and the opening OP is covered from the outdoor side by them.

  The heat insulating lighting fixture AL is an inner window provided so as to cover the opening OP from the indoor side, and includes sliding doors 40 and 40. As shown in FIG.1 and FIG.3, the sliding doors 40 and 40 are arrange | positioned so that each may cover the left part and the right part of the opening part OP.

  As shown in FIGS. 1 and 2, the L-shaped angle 10 is fixed above the frame 19 and the window base 16 is fixed below the frame 19 on the indoor side surface of the inner wall W. The L-shaped angle 10 is a metal thin plate bent so as to have a substantially L-shape when viewed from the side, and includes a base portion 12 that is in contact with and fixed to the inner wall W, and an indoor side from the upper end of the base portion 12. The connecting portion 13 extends substantially horizontally, and the engaging portion 14 hangs down from the end of the connecting portion 13.

  The sliding doors 40 and 40 are disposed between the L-shaped angle 10 and the window base 16. The sliding doors 40 and 40 each have a frame member 20 and a face member 30 held by the frame member 20.

  The frame member 20 includes an upper frame 21 and a lower frame 22 (see FIG. 1) and a pair of left and right vertical frames 23 and 23 (see FIGS. 1 and 3) that are spaced apart from each other. The vertical frames 23, 23 extend in the vertical direction so as to connect the left and right ends of the upper frame 21 and the lower frame 22. As shown in FIG. 2, a groove 17 that is recessed downward is formed at the upper ends of the upper frame 21 and the vertical frames 23, 23. A rotatable door wheel 25 is fixed to the lower part of the lower frame 22.

  As shown in FIG. 3, the face material 30 has a plate shape as a whole, and covers the opening OP with one side surface 30a in the thickness direction facing the indoor side and the other side surface 30b facing the outdoor side. Further, as will be described in detail later, the face member 30 is configured by overlapping a plurality of translucent panels in the thickness direction, and the periphery thereof is held by the frame member 20.

  In the sliding doors 40 and 40 configured in this way, the groove 17 formed at the upper end of the frame member 20 and the locking portion 14 of the L-shaped angle 10 are locked, and the door wheel 25 is formed on the upper surface of the window base 16. By being placed in the groove 17 and rotating, the L-shaped angle 10 and the window base 16 can be slid in the horizontal direction. The sliding doors 40, 40 can slide until they come into contact with door stops 18, 18 provided at both ends of the window base 16.

  Next, with reference to FIG.4 and FIG.5, the specific structure of the sliding door 40 is demonstrated in more detail. 4 is a sectional view showing details of the sliding door shown in FIG. 3, and FIG. 5 is an exploded perspective view showing a face material of the heat insulating lighting fixture according to the embodiment of the present invention.

  The face material 30 is formed by superimposing three panels, an indoor side panel 31, an outdoor side panel 32, and an internal panel 33 sandwiched therebetween, in the thickness direction of the face material 30 indicated by an arrow Z in FIG. It consists of

  The indoor side panel 31 has a plate shape as a whole, and is composed of two thin surface plates 31a and 31b facing each other and a thin plate-like rib 31c connecting the surface plates 31a and 31b. A plurality of ribs 31c are provided at predetermined intervals in the short side direction of the indoor side panel 31 (for convenience of explanation, illustration of some of the plurality of ribs 31c is omitted in FIG. 5). The same applies to ribs 32c, 331c, 332c, and 333c described later).

  The plurality of ribs 31 c are parallel to each other and extend in the longitudinal direction of the indoor side panel 31. By setting the extending direction of the rib 31c as the longitudinal direction of the indoor side panel 31, the indoor side panel 31 itself resists a bending moment around the X axis (see FIG. 5) that is an axis perpendicular to the longitudinal direction. Rigidity can be ensured. Most general-purpose panels distributed in the market adopt the same configuration. The space between the surface plates 31a and 31b is partitioned into a plurality of spaces 31d by a plurality of ribs 31c.

  The indoor side panel 31 employs polycarbonate as a material and has high translucency. As described above, since the plurality of ribs 31c are parallel and extend only in the longitudinal direction of the indoor side panel 31, the surface plates 31a and 31b and the plurality of ribs 31c are arranged in the direction of the arrow Y shown in FIG. It can be molded integrally by extrusion molding. Such a panel made of polycarbonate suitable for mass production is inexpensively distributed as a general-purpose building material whose use is not limited, and can be easily procured. This indoor side panel 31 is also constituted by such a general-purpose panel, and is used by cutting one general-purpose panel and adjusting its size.

  The outdoor side panel 32 is a general-purpose panel similar to the indoor side panel 31. And the rib 32 c inside thereof extends only in the longitudinal direction of the outdoor side panel 32.

  The internal panel 33 is a general-purpose panel made of polycarbonate of the same type as the indoor side panel 31 and the outdoor side panel 32, but the three general-purpose panels of the first internal panel 331, the second internal panel 332, and the third internal panel 333 are straightened. It is greatly different in that it is configured by arranging and connecting together. In each of the first inner panel 331, the second inner panel 332, and the third inner panel 333, a rib 331c, a rib 332c, and a rib 333c extend so as to be parallel to each other.

  The face material 30 is configured by overlapping the indoor side panel 31, the outdoor side panel 32, and the internal panel 33 as described above in the thickness direction. Specifically, first, in the indoor side panel 31 and the outdoor side panel 32, the extending direction of the ribs 31 c and 32 c is substantially the same as the longitudinal direction of the face material 30 (the direction of the arrow Y in FIG. 5). Has been placed. That is, the longitudinal direction of the indoor side panel 31 and the outdoor side panel 32 is made to coincide with the longitudinal direction of the face material 30.

  Next, the rib 331c, 332c, 333c of the internal panel 33 extends in the width direction of the face material 30 (the direction of arrow X in FIG. 5), and the thickness direction of the face material 30 (the direction of arrow Z in FIG. 5). ), The extending direction is arranged so as to intersect the extending direction of the ribs 31c and 32c of the indoor side panel 31 and the outdoor side panel 32 substantially at right angles. In other words, when the ribs 31c and 32c of the indoor side panel 31 and the outdoor side panel 32 and the ribs 331c, 332c and 333c of the internal panel 33 are projected in the thickness direction of the face material 30, they overlap and intersect. Placed in.

  The overlapped indoor side panel 31, outdoor side panel 32, and internal panel 33 are sandwiched in the thickness direction of the face material 30 by the indoor side plate 23a and the outdoor side plate 23b of the vertical frame 23, as shown in FIG. It is constructed integrally. A steel channel 26 is sandwiched between the indoor side plate 23a and the outdoor side plate 23b to enhance the rigidity of the vertical frame 23.

  When the indoor side panel 31, the outdoor side panel 32, and the internal panel 33 are overlapped in this way, when viewed along the thickness direction of the face material 30, the face material 30 is caused by the intersection of the extending directions of these ribs. It seems that a rectangular lattice is formed inside the. This makes it possible to protect privacy by reducing visibility from the outdoor side while securing daylighting.

  Furthermore, each of the indoor side panel 31, the outdoor side panel 32, and the internal panel 33 is partitioned into a plurality of spaces by ribs between the two surface plates. Therefore, by constructing the face material 30 by superimposing these panels, the physical boundary surface increases between the indoor side and the outdoor side, and of course, the heat insulation is improved, and the partition is formed by the ribs. The heat insulation can be improved also by the air present in each space.

  In addition, the indoor side panel 31 and the outdoor side panel 32 are both arranged such that the extending direction of the ribs 31 c and 32 c is substantially the same as the longitudinal direction of the face material 30. Thereby, when using the general-purpose panel as the indoor side panel 31 and the outdoor side panel 32, the indoor side panel 31 and the outdoor side panel 32 are respectively connected to each other by making the longitudinal direction coincide with the longitudinal direction of the face material 30. It is easy to configure with a single general-purpose panel. In other words, it is not necessary to configure the indoor side panel 31 and the outdoor side panel 32 by arranging a plurality of general-purpose panels in the longitudinal direction of the face material and connecting them together.

  Here, as for the internal panel 33, a large general-purpose panel having a width dimension equivalent to the longitudinal dimension of the face material 30 is not prepared in the market while the width direction of the face material 30 is set to the extending direction of the rib. As described above, the first inner panel 331, the second inner panel 332, and the third inner panel 333 are linearly arranged and connected. Accordingly, as shown in FIG. 5, a joint P1 appears between the first inner panel 331 and the second inner panel 332, and a joint P2 appears between the second inner panel 332 and the third inner panel 333. .

  However, according to the face material 30 according to the present embodiment, the joints P1 and P2 are covered with the indoor side panel 31 and the outdoor side panel 32 that are both formed of one general-purpose panel and do not have a joint. Therefore, the joints P1 and P2 do not stand out from the outside. That is, according to this embodiment, it is possible to improve the heat insulation and lower the visibility by visually forming a lattice with ribs while improving the design.

  The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to these specific examples. In other words, those specific examples that have been appropriately modified by those skilled in the art are also included in the scope of the present invention as long as they have the characteristics of the present invention. For example, the elements included in each of the specific examples described above and their arrangement, materials, conditions, shapes, sizes, and the like are not limited to those illustrated, but can be changed as appropriate. Moreover, each element with which each embodiment mentioned above is provided can be combined as long as technically possible, and the combination of these is also included in the scope of the present invention as long as it includes the features of the present invention.
