BACKGROUND OF THE INVENTION
The present invention relates to a single-action telescopic horizontal shutter that is installed and used in an opening of a building.
[0002]
[Prior art and problems to be solved by the invention]
As this kind of single-action telescopic horizontal shutter, the present inventor has proposed, for example, Japanese Patent Application No. 11-243149. According to this, a plurality of telescopic links in the longitudinal direction are arranged between a pair of vertical rails. The telescopic unit bodies that can be individually expanded and contracted are formed, and the adjacent vertical bars of the respective elastic unit bodies are hinged at the indoor side or the outdoor side end portion to form a shutter body that can freely rotate the respective elastic unit bodies. The shutter body can be freely opened and closed in the cross direction by being suspended from a pair of opposed guide rails arranged vertically so as to reach the opening surface and the storage portion in the cross direction through the direction changing curved portion. At this time, the curved portion for changing the direction of the guide rail is configured to have a radius of curvature as small as possible to form a circular arc of a flat quarter circle, while the expansion width of the expansion / contraction unit body is set to be For direction change By setting the width wider than the length of the string connecting the ends of the curved portions, the shutter main body is configured to expand and contract at the opening surface, and the expansion and contraction unit is allowed to pass through the curved portion in a contracted state. The shutter body is opened so as to be housed in the housing portion, and the shutter body is closed so that the expansion unit can be passed through the curved portion in the contracted state and extended on the opening surface, so that the shutter body can be opened and closed. In particular, when the drawer unit is pulled out from the storage unit, the retractable unit is stretched so that the smooth passage of the curved unit is not hindered. For this purpose, a pressing means, for example, a biasing means using a spring, is installed between the storage portion and the shutter body.
[0003]
[Problems to be solved by the invention]
In this case, the shutter main body can be stored in a storage portion intersecting the opening surface through a curved portion having a circular arc of a flat quarter with a radius of curvature as small as possible, and the opening surface can be fully opened. In addition, even if the curved portion has a radius of curvature as small as possible and forms a circular arc of a quarter circle, the shutter body can pass smoothly, and the expansion / contraction unit individually expands / contracts, so that the shutter body Although it is possible to obtain advantages such as being able to be opened and closed lightly, on the other hand, it is generally necessary to install a pressing means between the storage portion and the shutter body, so that the structure as a horizontal shutter tends to be complicated. When this is used as the spring biasing means, the spring will be expanded and contracted every time the shutter body is opened and closed, so maintenance such as replacement is necessary. Leaving the potential to be in.
[0004]
The present invention has been made in view of such circumstances, and the problem to be solved is to maintain the merit realized by the horizontal shutter as it is and eliminate the need for the pressing means, and to make a simple structure and smooth opening and closing. The object is to provide a single-action telescopic horizontal shutter that can be secured.
[0005]
[Means for Solving the Problems]
In accordance with the above problems, the present invention pays attention to the relationship between the bending portion and the expansion width of the expansion / contraction unit body of the shutter body (referred to as the internal width of expansion / contraction unit when the expansion / contraction link is expanded). By setting the extension width of the telescopic unit to a narrow width relative to the length of the string connecting the ends of the parts, the shutter body can be reduced by simply hanging the shutter body on the guide rail. Opening of the state and closing of the individually extended state of the expansion and contraction unit body were conducted with the knowledge that smooth bending portion passage and opening and closing are possible without installing the pressing means, etc. According to a first aspect of the present invention, a plurality of telescopic links in the longitudinal direction are arranged between a pair of vertical rails to form individually extendable telescopic unit bodies, and adjacent vertical rails of the respective telescopic unit bodies are arranged on the indoor side. Or at the outdoor end The upper and lower sides of the shutter body, which are connected to each other to form a shutter body in which each telescopic unit body is rotatable, are arranged so as to reach the opening surface and the storage portion in the crossing direction through the curved portion for changing direction. In a horizontal shutter that can be opened and closed in the cross direction by mounting it on a pair of opposed guide rails, the above-mentioned suspension mounting is installed at the indoor and outdoor center positions of one of the pair of telescopic units. Then, it is performed by the upper suspension roller placed on the upper guide rail and the steadying roller engaged with the lower guide rail, and the curved portion for changing the direction of the guide rail is made as small as possible with a radius of curvature of a plane 1/4 circle. And the expansion width of the expansion / contraction unit is set to be narrower than the length of the string connecting the ends of the direction-changing curved portion, The expansion / contraction unit body is reduced at the opening surface when the pressure is opened and the bending of the contracted main body of the shutter body is extended. This is a single-acting telescopic horizontal shutter characterized by being able to pass through the part freely.
[0006]
In addition to the above, the invention according to the second aspect of the present invention reduces the dead space on the side of the opening surface by installing a horizontal shutter by setting the curved portion as small as possible to a radius of curvature, and reduces the expansion width of the expansion unit. As a width suitable for crime prevention to prevent passage, it is preferable that both the radius of curvature and the extension width are compatible. The single-action telescopic horizontal shutter according to claim 1, wherein the body has an extension width of about 20 cm or less.
[0007]
The present invention uses each of these as the gist of the invention as means for solving the above problems.
[0008]
[Action]
In the present invention, the expansion / contraction unit of the shutter main body is individually reduced when, for example, the door toe is pressed, and is individually extended by pulling the door toe. If the shutter body is opened and closed by being electrically operated, when the opening is opened, the expansion unit is sequentially reduced from the side of the door toe, for example, and the shutter body is in a reduced state and curved. When the shutter main body stored in the storage portion is closed, the retractable unit body, for example, on the side of the door toe is applied. The leading portion of the bending portion is guided by the upper and lower guide rails of the bending portion, and the expansion / contraction unit narrower than the string connecting the both ends of the bending portion is extended in the bending portion and further receives the attraction force to bend the bending portion. Pass through each extension By repeating this unit body successively acts as closure of the individual expanded state of the telescopic unit of the shutter body is made.
[0009]
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. The telescopic unit bodies are rotatable by connecting the hinges 5 at the indoor side or outdoor side end.
[0010]
That is, in this example, the shutter main body 1 is provided with a door-end rod 6 on the door-end side, and a number of expansion / contraction unit bodies 2 are subsequently arranged. The expansion / contraction unit body 2 is made of aluminum, for example, A pair of vertical bars 3 made of aluminum extruded material is used, and the pair of vertical bars 3 are arranged in a plurality of longitudinal directions, for example, about 2 to 4 in the longitudinal direction. In this case, the telescopic link 4 is configured to be individually stretchable by using the telescoping unit body 2 that can be stretched independently and independently. The telescopic link 4 of this example is made of a suitably shaped aluminum link bar such as a straight line or an S-shape, for example, an aluminum extruded material, an aluminum casting link bar or the like arranged in an X-shape, and a pair of vertical bars. One end pivotable with respect to 2 The other end of the telescopic unit 2 is individually expanded and contracted by slidably engaging the other end in the longitudinal direction and pivotally supporting each other at the X-shaped intersection as required. A pair of vertical bars 3 are connected.
[0011]
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.
[0012]
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.
[0013]
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.
[0014]
In this example, one of the adjacent vertical bars 3 of the telescopic unit 2 connected to the hinge 5 protrudes to the side of the other vertical bar 3 and superposes on the surface of the adjacent vertical bar 3 when closed. In this example, the gap blindfold fin 33 is formed by arranging the gap blind fin 33 for blindly covering the V-shaped groove formed between the vertical bars 3. One vertical beam 3 adjacent to each other, and in this example, the hinge 5 is set to the full length in the longitudinal direction of the vertical beam 3 from the outdoor end of the vertical beam 3 on the door end side of the opening surface toward the other vertical beam 3 side. As a result of the cross-curved lines in the shape of a plane arc that crosses and superimposes the front surface of the other vertical beam 3 substantially entirely without obstructing the mutual rotation of the vertical beams 3 by The V-shaped groove-like gap between the vertical bars 3 is concealed.
[0015]
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 inside of the vertical beam 3 provided with the one gap blindfold fin 33 and the outside end of the vertical beam 3 are curved into a plane arc shape, and the gap blind fin 33 is projected so as to continue the arc. The interior side of the vertical beam 3 not provided with the other gap blindfold fin is similarly curved in a plane arc shape, and the exterior side is made flat so as to be orthogonal to the substrate 31. Eye The pair of vertical bars 3 in this example has a longitudinal length of, for example, about 5 to 6 cm, and the hinge 5 at the indoor side end thereof. Therefore, when this is stretched and closed, for example, there is a tendency to generate a gap in the V-shaped groove having a width of about 8 to 9 mm at the maximum. However, as a result of the gap blindfold fin 33 covering the gap, A gap is not exposed on the front surface of the extended shutter body 1 but is hidden.
[0016]
The shutter body 1 formed in this way is placed on a pair of guide rails 10 which are vertically opposed to each other so as to reach the opening surface 11 and the storage portion 13 in the crossing direction through the curved portion 12 for direction change. In the present embodiment, the shutter body 1 can be attached to the guide rail 10 by hanging it up and down, and this is attached to one of the vertical bars 3 of the pair of the extension unit 2. It is carried out by an upper suspension roller 7 installed on the upper guide rail 10 and installed on the upper and lower guide rails 10 and an anti-swing roller 8 engaged with the lower guide rail 10, respectively. The steady rest roller 8 is a guide rail by being rotatably installed at the indoor / outdoor central position of one of the vertical bars 3 of the pair of the door toe 6 and the telescopic unit 2. 0 are to perform the opening and closing guide by.
[0017]
At this time, the bending portion 12 for changing the direction of the guide rail is configured to have a radius of curvature as small as possible to form a circular arc of a flat quarter circle, and the expansion width of the expansion / contraction unit body 2 is increased. The width is set to be narrower than the length of the string connecting the ends of the bending portion 12 for turning direction. In this example, the curvature radius of the bending portion 12 for turning direction is 15 ± 3 cm. The expansion width of the expansion / contraction unit 2 is about 20 cm or less.
[0018]
That is, in this example, the radius of curvature of the curved portion 12 forming the circular arc of the flat quarter circle is set to 15 ± 3 cm. By making this as small as possible, the opening surface 11 by installing the horizontal shutter A is used. The occurrence of dead space on the side is reduced, and if it exceeds 18 cm, the occurrence of dead space tends to increase. On the other hand, if it is less than 12 cm, the opening and closing guide by the guide rail 10 may not be smooth. In addition, the reason why the extension width is set to about 20 cm or less is that an adult can enter the interior from between the vertical bars 3 other than the telescopic link 4 when the extension width is exceeded, preferably about 17 cm or less. , It is preferable to prevent children from entering.
[0019]
In this example, the radius of curvature is, for example, 15 cm, and the extension width of the expansion / contraction unit 2 is about 15 cm, which is narrower than the length of the chord of about 21 cm at the radius of curvature of 15 cm, and the radius of curvature is 15 cm. Thus, in the suspension of the shutter body, the upper suspension roller 7 and the steadying roller 8 can be guided very smoothly by the guide rail 10 while rotating, and the extension width of the telescopic unit 2 is 15 cm or less. In particular, by setting it to about 14 cm, the possibility of intrusion of people, including children, between the vertical beams 3 of the telescopic unit 2 is eliminated, and the security performance when the shutter body 1 is closed is improved by using an auxiliary beam, etc. Highly secured by setting the interval of the vertical beam 3 without using it.
[0020]
Reference numeral 14 in the figure indicates that the expansion / contraction unit 2 is provided with the gap blindfold fin 33 in the present example, so that when the expansion / contraction unit 2 passes through the bending portion 12 and becomes in series with the opening surface 11, the gap blindfold is shown. In order to prevent the danger caused by the exposure of the curved portion 12 in this example, the upper and lower sides of the fins 33 may be dangerous. The curved portion cover 14 is installed on the outer side of the curved portion 12 of the pair of opposed guide rails so as to cover the curved portion 12, and the curved portion cover 14 of this example is provided with upper, lower, left and right frames, and a metal such as aluminum, for example, For example, about 2 cm at a position near the end of the opening surface 11 so as to cover the curved portion 12 from a position near the end of the opening surface of the guide rail 10. There as being placed in proximity to the guide rail 10 via a gap. Similarly, reference numerals 15 and 16 denote anchors and brackets for fixing the bending portion cover 14.
[0021]
With the configuration as described above, in the horizontal shutter A of the present example, the shutter main body 1 is configured to reduce the expansion / contraction unit body 2 at the opening surface at the time of the pressing opening and pass through the curved portion of the shutter main body 1 in the reduced state. The extension unit 2 can be extended at the bending portion when the shutter main body 1 is closed and closed, and the extension unit 2 can be passed through the bending portion in the extended state. That is, the expansion / contraction unit body 2 of the shutter body 1 is individually reduced when, for example, the door toe 6 is pressed, and is individually extended when the door toe 6 is pulled. If the shutter body 1 is opened and closed by performing the above, when the opening is made, a pressing force is applied. For example, the telescopic unit 2 is sequentially reduced from the door end 6 side, and the shutter body 1 is reduced. Then, when the shutter body 1 housed in the housing part 13 is closed, the door is retracted and passed through the curved part 12 and opened in its reduced state and housed in the housing part 13. The leading portion of the expansion / contraction unit 2 on the tip 6 side is guided by the upper and lower guide rails 10 of the bending portion 12, and the expansion / contraction unit 2 narrower than the string connecting the ends of the bending portion 12 extends at the bending portion 12. As it becomes To pass through the bending portion 12 receives the attracting force by the stretching unit body 2 is repeated successively this, so closing of the individual expanded state of the telescopic unit body 2 of the shutter main body 1 is made.
[0022]
And in this case, while maintaining the merits such that the opening surface 11 can be fully opened, the shutter body 1 can smoothly pass through the curved portion 12, and the shutter body 1 can be opened and closed lightly. Installation of the pressing means and the like is not required, and a simple structure can be provided to ensure smooth opening and closing.
[0023]
Although the illustrated example is as described above, the above-mentioned elastic link is installed at both upper and lower ends of the elastic unit body, and the decorative link is arranged at an intermediate position between the elastic links of the single or plural elastic unit bodies. 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. In implementing the present invention, including displaying characters and figures and using a shutter body with decoration, etc., the shutter body, telescopic unit, vertical bar, telescopic link, guide rail, curved Each specific shape, material, structure, dimension, relationship between them, addition to these, etc. of the parts, storage parts, etc. can be in various forms as long as they do not contradict the gist of the invention.
