BACKGROUND OF THE INVENTION
The present invention relates to a single-action telescopic shutter that is installed and used in an opening of a building.
[0002]
[Prior art and problems to be solved by the invention]
The inventor arranges a plurality of telescopic links in the longitudinal direction between a pair of longitudinal bars to form individually stretchable telescopic unit bodies, and connects adjacent vertical bars of the respective telescopic unit bodies to the indoor side or outdoor side end. And a pair of guides facing each other up and down in which the shutter body is arranged so as to reach the opening surface and the storage portion in the crossing direction through the curved portion. A single-action telescopic horizontal shutter that can be opened and closed in the cross direction by hanging on the rail is proposed. On the other hand, when the shutter body is in the expanded and closed state, the expanded telescopic links of each telescopic unit are mutually reduced. As a result of the hinge connection at the indoor side or outdoor end being slightly rotated by this inquiry, resulting in the opening of the free end on the unconnected side of the vertical beam. According to Japanese Patent Application Laid-Open No. 2001-214676, the adjacent one of the hinge-connected vertical bars projects to the other vertical rail side so as to easily and surely eliminate the gap and ensure the appearance quality of the shutter body. It has been proposed that the shutter main body is provided with, for example, fin-shaped gap blindfold fins, which are superposed on the surfaces of adjacent vertical bars and blindly cover the V-shaped groove-like gaps generated between the vertical bars when closed.
[0003]
Each of the telescopic unit bodies can be individually expanded and contracted, so that the possibility of a hand being caught between vertical bars as in the case of a conventional shutter body that expands and contracts simultaneously can be eliminated. In the case of a fin-like shape with gap blindfold fins that overlap with the vertical bars of adjacent telescopic unit bodies, when the shutter body is closed, the shutter body passes through the curved portions of the pair of guide rails that face each other up and down. When the expansion units are in series with each other on the opening surface, the gap blindfold fins overlap in the crossing direction with the vertical bars of the adjacent expansion unit, and as a result, for example, a hand is inserted into the V-shaped groove. If the shutter main body is closed in this state, there is a possibility that a risk of fracture, finger cutting, etc. may be caused by the cutter action of the gap blindfold fin.
[0004]
Particularly, the shutter body can pass through a curved portion having a radius as small as about 15 cm, for example, by hinge-connecting the indoor side or outdoor side end of the telescopic unit, and in this case, the opening is as large as possible. The shutter body can be stored in a storage section that intersects the opening surface, and a horizontal shutter can be formed in a compact form. On the other hand, in order to place the telescopic unit bodies in series with a curved portion having a small radius. , Since the polymerization speed in the crossing direction of the gap blindfold fins is increased, the possibility of causing the above danger is increased.
[0005]
The present invention has been made in view of such circumstances, and its solution is to superimpose the V-shaped groove of the expansion / contraction unit body in the shape of a fin that conceals the vertical beam of the adjacent expansion / contraction unit body. It is an object of the present invention to provide a single-action telescopic horizontal shutter capable of ensuring a high level of safety by eliminating the above-mentioned danger due to the cutter action during the polymerization caused by installing gap blindfold fins.
[0006]
[Means for Solving the Problems]
In accordance with the above-described problem, in the present invention, the expansion unit is in series with the curved portion of the guide rail from the curved portion to the opening surface. By installing a curved cover so as to cover, the above-mentioned danger is eliminated by preventing the hand from being inserted from outside the shutter into the V-shaped groove-like gap between the vertical bars of the telescopic unit. In other words, the invention according to claim 1 is arranged such that a plurality of telescopic links in the longitudinal direction are arranged between a pair of longitudinal rails to form individually stretchable telescopic unit bodies and adjacent vertical rails of the respective telescopic unit bodies. The telescopic unit bodies can be pivoted by connecting the hinges to each other at the indoor side or the outdoor side end, and the adjacent vertical beam protruding from the adjacent vertical beam to the other vertical beam side. Polymerized on the surface and lived between vertical bars when closed Forming a shutter body provided with gap-folding fins that cover and cover the V-shaped groove-like gap, and the shutter body is arranged so as to reach the opening surface and the storage section in the crossing direction through the curved portion. In a horizontal shutter that can be opened and closed in the cross direction by being suspended on a pair of opposed guide rails, the vertical beam is made of an aluminum extruded material, and the gap blindfold fin that protrudes and projects from one vertical beam is attached to the vertical shutter. By forming a curved surface in the shape of a flat circular arc with a thickness corresponding to the thickness of the extruded aluminum material, the outer surface of the other vertical rail can be overlapped on the inside substantially in the intersecting direction and the guide rail is curved. Cutter action on fingers by crossing the gap blind fins in a crossover direction with a small radius of curvature of about 15 ± 3 cm and covering the outside of the curved part In order to solve the above-mentioned problem, a single-action telescopic horizontal shutter that is provided with a bending portion cover for preventing insertion of fingers is used as a gist of the invention as means for solving the above problems.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
In the following, the present invention will be described in more detail with reference to the drawings. A is a single-action telescopic horizontal shutter made of aluminum in this example, 1 is a shutter body of the shutter A, and 10 is a guide rail. The shutter main body 1 has a plurality of telescopic links 4 in the longitudinal direction between a pair of vertical bars 3 to form individually extendable telescopic unit bodies 2 and adjacent vertical bars 3 of the respective telescopic unit bodies 2 to each other. A hinge 5 is connected at the indoor side or outdoor side end portion so that each telescopic unit can be rotated, and the adjacent vertical beam 3 connected to the hinge 5 protrudes and is adjacent to the other vertical beam 3 side. It is assumed that gap blindfold fins 33 are formed so as to blindly cover the V-shaped groove-like gap generated between the vertical bars 3 when they are superposed on the surface of the vertical bars 3 and closed.
[0008]
The telescopic unit body 2 uses a pair of vertical bars 3 made of an aluminum extruded material, and the pair of vertical bars 3 are arranged in a plurality of longitudinal directions, for example, about 2 to 4 places in the longitudinal direction. The telescopic link 4 is configured to be telescopically connected by the telescopic link 4 at the front and rear intermediate positions of the vertical beam 3. At this time, the telescopic link 4 is used to make the telescopic unit body 2 independently and independently stretchable. The telescopic link 4 of this example is made of an appropriately shaped aluminum such as a straight line or an S-shape, for example, an aluminum extruded material, an aluminum casting link bar or the like in an X-shape. One end is pivotally supported with respect to each of the pair of vertical bars 2, and the other end is slidably engaged in the longitudinal direction. The telescopic unit body 2 is pivotally supported. Are so as to consolidate the pair of vertical bars 3 performs a separate stretch.
[0009]
At this time, the expansion / contraction link 4 of this example is disposed at two longitudinal ends of the expansion / contraction unit 2 in the vicinity of the guide rail 10 and in the middle thereof, thereby stabilizing the expansion / contraction of the shutter body 1 as much as possible. And it is surely done.
[0010]
In this example, the hinge 5 between the adjacent vertical bars 3 is connected to the indoor side or the outdoor side of the telescopic link 4, in this example, at the end of the vertical bar 3 on the indoor side. , Thereby individually and independently expanding and contracting the expansion and contraction unit bodies 2 are connected to each other in the expansion and contraction direction so as to be a single-action expandable and turnable unit. It is designed to be retractable in the direction intersecting the opening.
[0011]
That is, in this example, the hinge 5 is connected by arranging the hinge 5 at the indoor corner portion on the contact side of the vertical beam 3 which is adjacent to each other of the adjacent expansion and contraction unit bodies 2. The hinge 5 is installed in the longitudinal beam 3 with its entire length in the longitudinal direction as one shaft 51 and the other as a bearing 52. By fitting these together, for example, a rotation range of about 1/6 to 1/4 circle. An aluminum full surface hinge formed by an aluminum extruded material shaft and a bearing is used, and bending can be performed toward a substantially right-angled indoor side at each arbitrary hinge 5 portion.
[0012]
The gap blindfold fin 33 projecting from one vertical beam 3 to the other vertical beam 3 is curved into a planar arc shape having a thickness corresponding to the thickness of the aluminum extruded material of the one vertical beam 3. By forming, the front surface outside the other vertical beam 3 can be superposed freely in the crossing direction over the whole, and in this example, the gap blind fins 33 are connected to each other between the adjacent expansion and contraction unit bodies 2. One of the adjacent vertical bars 3, in this example, the length of the vertical bar 3 in the longitudinal direction from the outdoor end of the vertical bar 3 positioned on the door end side of the opening surface 11 to the other vertical beam 3 side is the hinge. The V-shaped groove between the vertical beams 3 is formed by the curved line formed in the plane arc shape so as to superimpose the other vertical beam 3 without hindering the mutual rotation of the vertical beams 3 by 5. The gaps in the shape are blindfolded.
[0013]
That is, the vertical rail 3 of this example has a common configuration in which the receiving groove 32 for rotatably receiving and fixing the end of the telescopic link 4 is provided on the side of the telescopic link 4 of the substrate 31. A pair of vertical rails 3 of the telescopic unit body 2 are made of different extruded aluminum shapes by making the outdoor shape different and providing the gap blind fins 33 on one side and not on the other side. The indoor side and the outdoor side end of the vertical beam 3 provided with the one gap blindfold fin 33 are curved in a plane arc shape, and according to the thickness of the aluminum extruded material so that the arc continues. The gap blindfold fin 33 having a thickness of about 1 to 2 mm is projected by making the thickness thick, and the indoor side of the vertical beam 3 not including the other gap blindfin fin is similarly curved in a planar arc shape. And outdoors Is formed in a flat shape so as to be orthogonal to the substrate 31 and is polymerized so as to enter the inside of the gap blind fins 33 on the outside of the room. Since the height is about 5 to 6 cm, and the indoor end is connected by the hinge 5, when this is extended and closed, for example, the gap of the V-shaped groove having a width of about 8 to 9 mm at the maximum is formed. Although there is a tendency to occur, as a result of the gap blindfold fin 33 covering the gap, the gap is not exposed on the front surface of the stretched and closed shutter body 1 but is blinded.
[0014]
The shutter main body 1 formed in this manner is suspended and mounted on a pair of guide rails 10 that are vertically opposed to each other so as to reach the opening surface 11 and the storage portion 13 in the intersecting direction via the curved portion 12. The pair of guide rails 10 that are vertically opposed to each other are made of an extruded aluminum material, and the curved portion 12 has a small radius of curvature of about 15 ± 3 cm, in this example 15 cm. Thus, the guide rail 10 is curved by a quarter of a circle with the curvature radius so as to have a substantially L-shaped plane.
[0015]
When the shutter body 1 is suspended from the guide rail 10, the upper suspension roller 6, the anti-sway roller, the pin, In this example, a rotatable steady roller 7 is installed, such as a slurry, and the upper suspension roller 6 is placed on the upper guide rail 10 on the upper frame, and the lower guide rail 10 on the lower frame in the steady roller 7. The curved portion 12 having a small radius of curvature of ¼ circle is formed by the upper suspension roller 6 and the steadying roller 7 rotating. A storage portion that is necessary and sufficient to be guided and advanced by the guide rail 10 and that the curved portion 12 is located at the end of the opening surface 11 and intersects the opening surface 11 3 obtained without the opening and closing of the shutter main body 1 smoothly between one as those made compact as a whole lateral pulling shutter A.
[0016]
At this time, a bending portion cover 14 for preventing finger insertion is installed so as to cover the outer side of the bending portion 12 of the pair of opposed guide rails up and down and to eliminate the cutter action on the finger due to the overlapping of the gap blindfold fins 33 The curved portion 12 is prevented from being exposed to the outside.
[0017]
The bending portion cover 14 of the present example is a narrow and vertically long panel body in which a frame such as aluminum, a metal, a resin, a tree, etc. is stretched on the upper, lower, left and right frames. The cover 14 has a height of about 20 cm so that the height of the cover 14 is adjusted to the horizontal shutter A and the curvature radius is 15 cm so as to cover the curved portion 12 of a quarter circle. In this example, the width is 23 cm. The curved portion cover 14 is fixed to one side end of the opening surface 11 on the upper and lower sides thereof by, for example, an anchor 15 with respect to a reinforcing bar of a frame, or is fixed to the guide rail 10 with a bracket 16. For example, by fixing the upper and lower ends of the side to the wall 16 or the column of the partition panel with the bracket 16, the upright installation is performed so as to cover the ceiling and the floor along the opening surface 11. Outside the opposite pair of guide rails 10 below, for example, through which a 2cm about small interval, the bending portion 12 are to be prevented from being exposed at the end position of the rotor surface 11.
[0018]
Therefore, in the shutter A of this example, in order to open the shutter main body 1, for example, the door toe 8 of the shutter main body 1 is pressed in the opening direction, that is, toward the storage section 13 on the indoor side or the outdoor side. When the telescopic link 4 of each telescopic unit body 2 is subjected to a pressing force, each telescopic unit body 2 is sequentially reduced and folded to reach the bending portion 13, and is further pressed to bend the bending portion 12 in the reduced state. In order to close the shutter body 1 while it is sent to the storage unit 13 and stored in the storage unit 13 to complete the reduction opening, the door rod 8 of the shutter body 1 stored in the storage unit 11 is closed. Is pulled out in the closing direction, that is, on the opening surface 11 side on the indoor side, the stretchable link 4 of the preceding stretchable unit body 2 receives a tensile force and sequentially stretches from the preceding stretchable unit body 2, It reaches the bend 12 and is still pulled Thus, in the extended state, it passes through the curved portion 12 and is drawn out to the opening surface 11 to complete the expansion and closing. When the expansion is closed, the expansion unit is extended from the bending portion 12 to the opening surface 11. The body 2 is forced to be in a series state by the guide rail 10, and the gap blindfold fins 33 overlap with the vertical beam 3 of the adjacent expansion / contraction unit 2 between the expansion / contraction unit bodies 2. If a hand or a finger is put between the vertical bars 3 before the polymerization, the gaps are superposed in the crossing direction, and in this example, the gap blindfold fin 33 having a thickness of about 1 to 2 mm and the substrate 31 of the vertical beam 3 on which it overlaps, Although the gap blindfold fin 33 acts like a cutter between the two, there is a possibility of injury, and in some cases, the possibility of cutting the finger, but the bending portion cover 14 outside the bending portion 12 Cover the gap blindfold This prevents the person from inserting the hand 33 between the vertical bars 3 including the mischief of the child's interest, and the like. The gap blindfold fins 33 can eliminate the risk of fractures, finger cuts, and the like due to the cutter action on the fingers during the cross direction polymerization.
[0019]

Characters and figures by links are displayed, or decorative links and vertical bars are colored, or a decorative part is arranged by fixing and arranging members on the vertical bars. Use a shutter body with decoration so that characters and figures are displayed, the curved cover should be made of a transparent mesh material, and the curved cover should be separated from the guide rail. In carrying out the present invention, including installation between the surfaces and installation on the wall surface, a pair of vertical rails, telescopic links, telescopic unit bodies, shutter bodies, guide rails, gap blindfolds Emissions, the specific shape of such curved cover, the material, structure, these relationships, the addition or the like for these, can be of various forms unless contrary to the gist of the invention.
