Description

  The present invention relates to a blindfold such as a face lattice fixed to the outside of a window for crime prevention and makeup purposes, and more specifically, a blindfold that can capture external wind well while preventing external see-through, and the same. Concerning face grids and fences.

  For example, the following patent document 1 has been proposed as the blinding of the surface lattice. This is a blindfold that is attached to a plane grid in which a plurality of vertical bars extending in the vertical direction are arranged in parallel. As shown in FIG. This is a structure having a belt-like substrate 103 to be adhesively fixed and a blindfold plate 104 extending from the belt-like substrate 103 in one of the left and right directions. Then, the pair of blindfold plates 104 attached to the adjacent vertical rails 102 and facing each other are bent so that one is located in the thickness direction front and the other in the thickness direction rearward within the thickness of the vertical rail 102. A gap 105 is formed between 104.

  However, the wind flowing in the plane direction in the plane lattice 106 portion is almost the surface because the width w of the gap 105a in the plane direction formed between the pair of blindfold plates 104 is narrow and shallow, as indicated by arrows in FIG. It is difficult to flow into the interior just by flowing through. For this reason, it was difficult to take in the wind through the window.

  Many houses in recent years have high airtightness and high thermal insulation specifications, and ventilation and ventilation through windows are very important. For example, in densely populated areas, the space between neighboring houses is extremely narrow, and wind flows from the front. Cannot be expected.

  Moreover, although the front-end | tips of the blindfold board 104 which opposes are the lengths which overlap, the fluoroscopy from the outside cannot be prevented completely with the overlap length of the grade currently disclosed by patent document 1. FIG. If this is to be completely prevented, the gap 105 between the blindfold plates 104 is further narrowed, and the shape of the air passage passing through the gap 105 is substantially Z-shaped in cross section, which impedes air permeability. Become.

  Therefore, the main object of the present invention is to obtain good air permeability and blindfold, and particularly to efficiently take in the wind flowing in the surface direction through the blindfold.

  Means therefor is a blindfold having a pair of left and right blindfolded surface portions, and a gap is formed between these blindfolded surface portions, and one of the blindfolded surface portions includes an introduction plate protruding forward, The introduction plate is bent toward the other blindfolded surface portion side, and the foremost position of the other blindfolded surface portion is formed at a position retracted from the foremost position of the one blindfolded surface portion. It is a blindfold formed so that the said clearance gap between blindfold surface parts may spread in the front-back direction.

  The one blindfolded surface portion and the other blindfolded surface portion may be formed as separate members, or may be configured as one piece, and the article to be attached is, for example, a surface grid or fence having a vertical rail If so, the vertical rail or the like is appropriately fixed to the object to be attached. Further, the one blindfold surface portion and the other blindfold surface portion may be integrated with the article or a member constituting the article.

  Another means for solving the problem is a surface lattice provided with the blindfold.

  In these configurations, the pair of blindfold plates prevents see-through from the outside, and the gap between them allows air to flow. Further, since the other blindfolded surface portion is in a position retracted from the one blindfolded surface portion, only one blindfolded surface portion protrudes forward, and a plurality of one blindfolded surface portion may be arranged in the left-right direction. Since the width of the gap in the juxtaposed direction between the adjacent one of the blindfolded surfaces can be widened, the wind flowing in the left-right direction in the vicinity of the blindfold hits one of the blindfolded surface portions and is taken into the interior.

  According to the present invention, it is possible to obtain good blindfolding and air permeability, and in particular, it is possible to efficiently take in the wind flowing in the left-right direction particularly in the blindfolded portion.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
1 is a perspective view of a surface lattice 31 to which the blindfold 11 is fixed, FIG. 2 is a plan view thereof, and FIG. 3 is a perspective view of the surface lattice 31 in a state where the blindfold 11 is separated. The illustrated surface lattice 31 is an example, and in this example, the surface lattice 31 is provided with a plurality of vertical bars 33 extending in parallel in the vertical direction on the front surfaces of two upper and lower horizontal bars 32 extending in the left-right direction. This is a so-called vertical lattice.

  As shown in these drawings and the enlarged cross-sectional view of FIG. 4A, the blindfold 11 has a pair of left and right blindfolded surface portions 12 and 13, and a gap 14 is formed between the blindfolded surface portions 12 and 13. Therefore, one of the blindfolded surface portions 12 and 13 includes an introduction plate 12a protruding forward, and the introduction plate 12a is bent toward the other blindfolded surface portion 13 side, and the other blindfolded surface portion. The foremost position of 13 is formed at a position retracted from the foremost position of the one blindfolded surface portion 12, and the gap 14 between the pair of blindfolded surface portions 12, 13 is formed so as to expand in the front-rear direction. Has been.

  More specifically, the blindfold 11 includes two types of blindfold members 22 including an introduction blindfold member 22 having one of the pair of left and right blindfold surface portions 12 and an auxiliary blindfold member 23 having the other 13 of the pair of blindfold surface portions. 23. The introduction blindfold member 22 and the auxiliary blindfold member 23 are fixed to the side surfaces of the two adjacent vertical bars 33 so as to face each other.

  These blind members 22 and 23 are formed of an appropriate material such as a synthetic resin or metal, and in the case of using a synthetic resin, the blind members 22 and 23 may have a light-transmitting property. Here, “having translucency” means a state in which light has a property of transmitting light, but the transmitted light is diffused, so that the shape or the like on the other side of the material cannot be recognized. As a result, blindfolding can be realized while incorporating light.

  The introductory blind member 22 is formed in an elongated shape having a length that fits between the upper and lower two horizontal beams 32 in the vertical beam 33, and the cross-sectional shape thereof is a flat fixed that is fixed to the side surface of the vertical beam 33. It has the board 12c and the introduction plate 12a extending forward from the tip of the fixed plate 12c, and the whole of the fixed plate 12c and the introduction plate 12a is the one blindfolded surface portion 12.

  The introduction plate 12a is shaped to bend in a circular arc so that the leading plate 12a is curved slightly at the tip side of the fixed plate 12c and then curved beyond the leading plate. The leading end 12b of the introduction plate 12a is the foremost position of the one blindfold surface portion 12. In addition, it may be bent to other shapes such as a shape that bends linearly.

  A part of the surface of the fixing plate 12c opposite to the bending direction of the introduction plate 12a is a fixing portion 12d fixed to the vertical rail 33, and the vertical rail 33 is fixed to the vertical rail 33 by a double-sided adhesive tape 25 (see FIG. 3). It is fixed against. In addition to the double-sided adhesive tape 25, for example, it may be fixed by an appropriate means such as a surface fastener, a screw, or a nail (not shown).

  In the illustrated example, the fixing plate 12c is set to have a length that protrudes rearward from the fixing portion 12d, that is, rearward from the rear surface of the vertical bar 33, so that sufficient blinding can be obtained. Depending on the conditions such as the bent shape and length of the introduction plate 12a, the rearward protrusion amount is appropriately set.

  The auxiliary blindfold member 23 is formed in an elongated shape having a length that fits between the upper and lower two horizontal beams 32 in the vertical beam 33, and the cross-sectional shape thereof is a flat fixed that is fixed to the side surface of the vertical beam 33. It has a plate 13c and an auxiliary plate 13a extending laterally from the front end of the fixed plate 13c toward the introduction blind member 22, and the whole of the fixed plate 13b and the auxiliary plate 13a is combined with the other of the blind surface portion. 13. Since the auxiliary plate 13a extends sideways as described above, this auxiliary plate 13a is the foremost position of the other blindfold surface portion 13.

  When the introduction blindfold member 22 and the auxiliary blindfold member 23 are fixed to the side surfaces of the vertical beam 33 facing each other, as shown in FIG. 4A, the tip 13b of the blindfold surface portion 13 is the one blindfold surface portion. An auxiliary plate 13a of the auxiliary blindfold surface portion 23 is formed so as to reach a virtual straight line L connecting the 12 front ends 12b and the rear end 12e. If the vertical bars 33 are manufactured so that the front end 13b of the blind surface portion 13 is in contact with the virtual straight line L (see FIG. 4A) in accordance with the wide pitch P1 of the vertical bars 33, as shown in FIG. As described above, it is possible to cope with the case where the pitch P2 is slightly narrower than that. Moreover, as shown in FIG.4 (c), by changing the fixing direction of the auxiliary blindfold member 23, it becomes possible to fix to the vertical bars 33 having a narrower pitch P3.

  In addition to this, for example, as shown in FIG. 5, it is possible to cope with the fixing to the vertical rail 33 having a narrow pitch by changing the fixing mode of the introduction blind member 22 and the auxiliary blind member 23. That is, the inner side surface of the fixing plate 13c of the auxiliary blind member 23 is fixed to one side surface instead of the both side surfaces of the vertical beam 33, and the fixing plate 12c of the introduction blind member 22 is fixed to the outer surface of the fixing plate 13c.

  Although the tip 13b of the auxiliary plate 13a reaches the virtual straight line L, the gap 14 for ventilation is formed between the auxiliary blind plate 22 and the introduction blindfold member 22.

  The gap 14 is a gap that extends in the front-rear direction between the introduction plate 12a that is bent and protrudes forward, and the auxiliary plate 13a that is located behind this, and the front end 13b of the auxiliary plate 13a and the fixing plate for the introduction blindfold member. It has a substantially L-shaped cross section consisting of a gap with 12c. The wider gap in the front-rear direction between the former introduction plate 12a and the auxiliary plate 13a is better because the wind can be taken in more smoothly. For example, as illustrated in FIG. 4A, the depth may be wider than the vertical bar 33.

  Also in this auxiliary blind member 23, a part of the surface of the fixing plate 13c opposite to the bending direction of the auxiliary plate 13a is a fixing portion 13d fixed to the vertical bar 33, as shown in FIG. It is fixed to the vertical beam 33 by appropriate means such as a double-sided adhesive tape 25.

  As shown in FIGS. 1 and 2, the blindfold 11 having the introduction blindfold member 22 and the auxiliary blindfold member 23 having the above-described configuration has the one blindfold surface portion as a boundary at an intermediate position in the left-right direction of the surface lattice 31. The twelve bending directions are fixed so as to face outward in the left-right direction. That is, the introduction blindfold member 22 is fixed to both side surfaces of the vertical beam 33 at the intermediate position in the left-right direction of the surface lattice 31 so as to be back-to-back, and the auxiliary blindfold member 23 and the introduction blindfold member sequentially in this direction outward from the left-right direction. 22 are fixed alternately.

  When the blindfold 11 is thus fixed, the blindfold 11 achieves the following operational effects.

  First, the blindfold 11 prevents see-through from the outside. That is, as described above, one of the blindfolded surfaces 12, that is, the distal end 13b of the auxiliary blindfold member 23 reaches the imaginary straight line L (see the phantom line in FIG. 4) connecting the distal end 12b of the introduction blindfold member 22 and the rear end 12e. Therefore, even if there is a gap 14 between the introduction blindfold member 22 and the auxiliary blindfold member 23, it is possible to completely prevent the inside from being seen through the gap 14.

  The fixing plates 12c and 13c of the introduction blindfold member 22 and the auxiliary blindfold member 23 are formed so as to protrude rearward, so that the introduction blindfold member 22 is completely prevented from protruding forward of the introduction plate 12a. It is possible to prevent see-through.

  And since it is comprised by two types of blindfold members 22 and 23, it can respond also to the difference in the space | interval of the vertical bar 33. FIG. In addition, transportation and management of the introduction blindfold member 22 and the auxiliary blindfold member 23 can be performed without being bulky.

  In addition, since it is possible to prevent complete see-through as described above, it is possible to suppress the blowing of rain and the entry of foreign matter.

  Next, the blindfold 11 efficiently causes the wind flowing in the surface direction through the surface lattice 31 portion to flow into the interior. That is, only one introduction blind member 22 of the blindfold 11 protrudes from the front surface of the surface lattice 31, that is, the front surface of the vertical rail 33, and spreads in the front-rear direction between the introduction blind member 22 and the auxiliary blind member 23. In addition, the gap 14 having a substantially L-shaped cross section leading to the inside is formed. For this reason, the wind flowing left and right in the plane direction is easily guided into the introduction plate 12a of the introduction blind member 22 and enters the inside.

  Moreover, even when a plurality of blindfolds 11 are arranged side by side, only one introduction blindfold member 22 of the blindfolds 11 fixed to the vertical rail 33 has a structure protruding forward, so that the adjacent introduction blindfold The distance to the member 22 is the same as the distance between the vertical bars 33, and is wider and deeper than when a blindfold that fits in the thickness of the vertical bars is fixed between the vertical bars as in the prior art. For this reason, as indicated by arrows in FIG. 6, the wind F1 flowing in the plane direction near the introduction blind member 22 depends on the speed, but the flow in contact with the introduction plate 12a is reduced in speed and the upper surface of the introduction plate 12a. Therefore, the flow is not uniform in the surface direction, and the flow is greatly undulated as a whole. Moreover, the wave of this flow is larger than that of the conventional one. As a result, not only the boundary layer F2 close to the introduction plate 12a but also the main flow F3 above the boundary layer F2 is likely to enter the gap 14. For this reason, coupled with the fact that the gap 14 has a substantially L-shaped cross section, the wind flowing in the plane direction through the surface lattice 31 can be efficiently taken into the inside through the gap 14.

  Further, since the blindfold 11 is fixed separately on the left and right sides of the surface lattice 31 so that the direction in which the introduction plate 12a bends is on the outside in the left-right direction, it is possible to satisfactorily capture the wind from either the left or right.

  As described above, in addition to obtaining a good blindfold effect, it is possible to efficiently take in the wind flowing in the left-right direction outside the window, and to obtain the surface lattice 31 with good air permeability. For this reason, for example, outside air can be suitably taken in a building or the like where the neighborhood is narrow, and the environment inside the building can be adjusted, thereby contributing to maintenance of the state of the building and human health.

  Hereinafter, other examples will be described. In this description, parts that are the same as or equivalent to those in the previous configuration are given the same reference numerals, and detailed descriptions thereof are omitted.

  As shown in FIG. 7, a blindfold 11 in which a current plate 15 orthogonal to the blindfold surface portion 12 and extending in the front-rear direction is formed at the middle portion of the one blindfold surface portion 12 in the vertical direction may be used. The “intermediate portion” means a portion excluding both ends in the vertical direction.

  The rectifying plate 15 adjusts the flow of air that enters, and suppresses convection in the gap 14 to facilitate air intake.

  In the illustrated example, the rectifying plate 15 is formed on one blindfolded surface portion 12, but even if it is formed on the other blindfolded surface portion 13, it is formed on both the blindfolded surface portions 12 and 13. There may be.

  8 and 9 show an example of the blindfold 11 in which the closing plates 16 extending to the other blindfold surface portion side are formed on the upper and lower ends of the one blindfold surface portion 12.

  That is, the blocking plate 16 has a shape that extends in the front-rear and left-right directions perpendicular to the blindfold surface portion 12 at both ends of the one blindfold surface portion 12 and closes the terminal of the one blindfold surface portion 12.

  The blocking plate 16 prevents the air that has entered between one blindfold surface portion 12 and the other blindfold surface portion 13 from leaking from the terminal to the outside. For this reason, it is possible to reduce wind uptake loss.

  FIG. 10 shows an example of the surface lattice 31 in which the bending direction of the one blindfolded surface portion 12 is set to be the same in the left-right direction, but the bending direction of the one blindfolded surface portion 12 is set to be different in the vertical direction. Indicates.

  That is, the length of the blindfold members 22, 23 is set to be shorter than the length corresponding to the length of the surface lattice 31 as in the above example, and the vertical direction of the surface lattice 31 is divided into four stages, The first and third stages from the top have the same direction, and the second and fourth stages from the top are set in the opposite directions.

  Even with such fixation, wind can be taken from either the left or right direction. Further, if the blindfold members 22 and 23 are appropriately combined, it is possible to cope with the difference in the vertical length of the surface lattice 31.

  In each of the above examples, the blindfold 11 in which one blindfold surface portion 12 and the other blindfold surface portion 13 are configured as separate members is shown. For example, as shown in FIG. You may use the blindfold member 24 which formed the adjacent one blindfold surface part 12 and the other blindfold surface part 13 integrally. In this case, both the fixing plates 12c and 13c may be configured by the fitting portion 17 having a U-shaped cross section so that the fixing plates 12c and 13c can be fitted and fixed to the vertical beam 33. In this case, it is preferable that the fitting portion 17 is made of a soft soft resin, and the introduction plate 12a and the auxiliary plate 13a are made of hard synthetic resin, and are molded by simultaneous extrusion of two kinds of resins. This is because the soft synthetic resin can cope with the difference in the length (W) of the vertical rail in the left-right direction. In FIG. 11 (a), 17a is a cutout portion having a circular arc shape that prevents deformation of the fitting portion 17 from affecting the angles of the introduction plate 12a and the auxiliary plate 13a. It is a locking claw that locks to the edge. Of course, you may fix using a double-sided adhesive tape.

  FIG. 11B and FIG. 11C show the introduction blindfold member 22 and the auxiliary blindfold member 23 that are fixed to the end portions of the surface lattice 31 in the left-right direction, respectively. Thus, by using the introduction blindfold member 22 having only the introduction plate 12a and the auxiliary blindfold member 23 having only the auxiliary plate 13a together with the blindfold member 24 (see FIG. 11A), FIG. A surface lattice in the state shown can be obtained.

  In addition, as shown in FIG.11 (d), many fine unevenness | corrugations 19 arranged in parallel with the insertion direction with respect to the vertical bar 33 instead of the said latching claw are formed in both the inner surfaces of a fitting part. Thus, it becomes possible to cope with the difference in the length D (see FIG. 11A) of the longitudinal rail 33 in the front-rear direction.

  FIG. 12 shows the fence 41 to which the blindfold shown in FIGS. 1 to 3 is fixed. Also in such a fence 41, the effect similar to the above is achieved.

In correspondence between the configuration of the present invention and the configuration of the one aspect,
One blindfold surface portion of the present invention corresponds to the one blindfold portion 12 and the introduction blindfold member 22,
Similarly,
The other blindfold surface portion corresponds to the other blindfold portion 13 and the auxiliary blindfold member 23,
The present invention is not limited to the above-described configuration, and other configurations can be employed.

  For example, the introduction blindfold member and the auxiliary blindfold member facing each other may be configured integrally.

  Moreover, the vertical grid | lattice | lattice or the vertical rail of a fence may integrate one blindfold surface part and an introduction board, and the other blindfold surface part and an auxiliary | assistant board.

  Furthermore, the type of the surface lattice is not limited to the vertical surface lattice, and may be a surface lattice or a fence other than those described above. In this case, in addition to the side surface of the vertical rail, it is fixed as appropriate, directly or using another member, depending on the shape of the surface lattice and the fence.

  Furthermore, the blindfold can also be used for doors and casings of closets and various storage boxes.
