  The present invention relates to an opening / closing body device that winds and stores opening / closing body means for partitioning a space, and more particularly to an opening / closing body device that prevents the winding means from being bent by winding of the opening / closing body means.

  FIG. 1 is a schematic view showing a configuration of a conventional awning apparatus. As shown in FIG. 1, for example, the awning device is attached to an outer wall of a building such as a store or a residential house via an attachment bracket 101. In FIG. 1, only the left side of the awning device is shown as a perspective view, and the configuration of only the left side shown will be described, but it is needless to say that a similar configuration exists on the right side. Omitted. The mounting bracket 101 has an E shape in which the upper side is long and the middle side and the lower side have the same length. A prismatic arm support frame 103 is fastened and fixed by bolts and nuts between the middle side and the lower side of the E-shaped mounting bracket 101. Link-type joint arms 105 and 106 having two degrees of freedom are attached via arm brackets 107 near the left and right ends of the arm support frame 103 and inside the mounting bracket 101. One end of the joint arm 105 and one end of the joint arm 106 are rotatably coupled via a joint member.

  The other end of the joint arm 105 is coupled to the arm bracket 107 via a joint member, and the other end of the joint arm 106 is rotatably coupled to the canvas support front frame 108 via the joint portion. Although not shown, the joint arms 105 and 106 have elastic bodies such as a tension coil spring that applies an urging force to extend the joint arms 105 and 106. Accordingly, the canvas support front frame 108 is always applied with an urging force to extend forward by the joint arms attached to the left and right. The canvas support front frame 108 is attached to one end side of a canvas 109 made of a synthetic fiber cloth that serves as a sunshade or rain cover. The other end side of the canvas 109 is wound around the winding pipe 110. The winding pipe 110 is rotatably supported by end brackets 111 attached to both ends of the arm support frame 103.

  The winding pipe 110 has a hollow pipe shape. When the awning device is electrically opened and closed, a rotary motor as a drive source is provided at either end of the winding pipe 110. The rotary motor is not shown because it is in the winding pipe 110. The outer side of the main body of the rotary motor and the inner side of the take-up pipe 110 are fixed, and the output shaft of the rotary motor is fixed to the end bracket 111 with bolts or the like. Accordingly, when the rotation motor rotates in the forward direction, the canvas 109 operates so as to be fed out, and when rotated in the reverse direction, the canvas 109 operates so as to be wound up. That is, the opening / closing operation of the canvas 109, which is an opening / closing body, is controlled by rotating the rotary motor in the forward and reverse directions.

The cover plate includes an upper cover 112 and left and right side covers 113 and 114. The upper cover 112 is composed of a plate material made of a curved aluminum alloy or the like whose front edge is curved downward and whose cross-sectional shape is substantially J-shaped, and the lower surface near both ends is attached to the mounting bracket 101 (on the right side). Are attached to the upper end of the cover plate but are not shown in the figure, and cover the take-up pipe 110 and the canvas 109 wound around it from above, and the side covers 113 and 114. Covers the left and right outer surfaces. Since the upper cover 112 is long in the left-right width direction, a substantially L-shaped support bracket is provided at a substantially intermediate position to prevent the deflection thereof so as to support the upper cover 112. Yes. The support bracket is not shown. As such an awning device, there are devices described in Patent Documents 1 and 2.
Japanese Utility Model Publication No. 03-092234 Japanese Utility Model Publication No. 03-092235

  The ones described in Patent Documents 1 and 2 are always extended forward by an elastic body such as a tension coil spring provided in the joint arms 105 and 106 attached to the left and right as described above. An urging force is applied to the canvas support front frame 108, and a rotary motor provided on the take-up pipe 110 is rotated in the forward and reverse directions so that the canvas 109 is taken up and unwound around the take-up pipe 110. The opening / closing operation of the canvas 109 is controlled.

  In this case, since the canvas 109 such as a synthetic fiber cloth is wound around the winding pipe 110 when the canvas is stored, the weight of the canvas 109 is applied to the winding pipe 110, and the winding pipe 110. If the length of the canvas 109 is large, the take-up pipe 110 bends due to the weight of the wound canvas 109, and the canvas 109 may become defective when the canvas 109 is wound or unwound. There was a possibility that a winding wrinkle would occur during the take-up.

  The present invention has been made in view of the above-described points. When the opening / closing member means for partitioning the space is wound and stored in the winding means, the winding means is bent by the winding of the opening / closing member means. An object of the present invention is to provide an opening / closing body device that can be prevented.

A first feature of the opening / closing body device according to the present invention is that the opening / closing body device includes an opening / closing body means for partitioning a predetermined space, and a winding means for winding or unwinding the opening / closing body means. The rotating shaft of the winding means slides in accordance with a change in the winding diameter of the opening / closing body means wound around the winding means by contacting the outer periphery of the opening / closing body means wound around the means. And supporting means for supporting the weight of the winding means.
Normally, when the opening / closing body device uses an opening / closing body means such as a sheet-like curtain to partition the opening of a building / house, factory, etc. The open / close state of the open / close body means is controlled by winding or rewinding. When the opening / closing body means is wound around the winding means, and the winding amount is increased, the weight of the winding means and the opening / closing body means wound around the winding means is increased, and the winding means is bent by the weight. Therefore, in the present invention, the support means for supporting the weight of the winding means wound around the opening / closing body means is provided while sliding the rotating shaft of the winding means. Since the support means is provided so as to come into contact with the outer peripheral portion of the opening / closing body means wound around the winding means, the support means supports the weight of the winding means wound around the opening / closing body means and is wound up. When the winding diameter of the opening / closing body means changes, the rotating shaft of the winding means is slid. Thereby, even if the weight of the wound opening / closing body means increases, it is possible to prevent the winding means from being bent by the weight.

A second feature of the opening / closing member device of the present invention is that, in the first feature, the support means has a substantially quarter-circular shape along the outer periphery of the opening / closing member means wound around the winding means. And a contact portion for smoothly guiding the opening / closing body means.
In this configuration, the support means is formed into a substantially circular shape so that the rotating shaft of the winding means can be easily slid and the weight of the winding means can be more effectively supported.

  According to the present invention, when the opening / closing body means for partitioning the space is wound around and stored in the winding means, there is an effect that the winding means can be prevented from being bent by the winding of the opening / closing body means.

  Hereinafter, preferred embodiments of an opening and closing body device according to the present invention will be described with reference to the accompanying drawings. In this embodiment, an opening / closing body device provided with a guide rail incorporating a gas spring will be described as an example.

  FIG. 2 is a perspective view showing an outline of the appearance of the opening / closing body device according to the present invention, and shows a state in which the canvas is stored. FIG. 3 is a view in which the upper cover is omitted from FIG. FIG. 4 is a diagram illustrating a state where the canvas is stretched. In FIG. 4, the upper cover is also omitted. FIG. 5 is a perspective view of FIG. 2 viewed from below. 6 is a view of the opening / closing body device of FIG. 2 as viewed from above. FIG. 7 is a side view of FIG. A new point adopted in the opening / closing body device according to the present invention is that a gas spring is built in the guide rail, and an urging force is applied to the canvas using the expansion and contraction action of the gas spring.

  As shown in FIGS. 2 to 7, the opening / closing body device is attached to a frame such as a terrace of a building such as a store or a residential house. The mounting bracket 201 has an elongated shape as a whole, and a central portion thereof is provided with a T-shaped projection, and the end brackets 202 and 203, the winding supports 204 to 206, Cover support frames 207 to 212 are fastened and fixed by bolts and nuts. In the vicinity of both left and right ends and the center of the mounting bracket 201, guide rails 301 to 303 having gas springs are attached to a frame such as a terrace. Caps 304 to 306 are provided at the distal ends of the guide rails 301 to 303, and the other ends are coupled to the mounting bracket 201.

  The canvas support front frame 401 is attached so as to move along the upper surfaces of the guide rails 301 to 303. Although not shown in FIGS. 2 to 7, moving frame bodies 402 to 404 that slide along the guide rails 301 to 303 are provided on the upper surfaces of the guide rails 301 to 303. Gas springs for applying an urging force for extending the canvas 200 to the moving frame bodies 402 to 404 are incorporated in the guide rails 301 to 303. The urging force that always tries to extend the moving frame bodies 402 to 404 that slide and move on the upper surfaces of the guide rails 301 to 303 attached to the left and right and the center of the mounting bracket 201, that is, the canvas supporting front frame 401, always forwards. It is added by a gas spring. Details of the gas spring will be described later.

  The canvas support front frame 401 is attached to one end side of a canvas 200 made of a synthetic fiber cloth that serves as a sunshade or rain cover. The other end side of the canvas 200 is wound around a winding pipe 213. The winding pipe 213 is rotatably supported by end brackets 202 and 203 attached to both ends of the mounting bracket 201.

  The winding pipe 213 has a hollow pipe shape. When the opening / closing body device is electrically opened / closed, a rotary motor as a drive source is provided at either end of the winding pipe 213. The rotary motor is not shown because it is in the take-up pipe 213. In the figure, the outer side of the main body of the rotary motor and the inner side of the take-up pipe 213 are fixed, and the output shaft of the rotary motor is fixed with bolts or the like so as not to rotate to the end bracket 202. Accordingly, when the rotation motor rotates in the forward direction, the canvas 200 operates so as to be fed out, and when rotated in the reverse direction, the canvas 200 operates so as to be wound up. That is, the opening / closing operation of the canvas 200 as the opening / closing body is controlled by rotating the rotary motor in the forward and reverse directions. As a drive source for rotating the winding pipe 213 which is a winding means, an electric system using the above-described motor or the like, or a manual system via other mechanisms may be used.

  The cover plate includes an upper cover 501 and side covers 502 and 503 at both left and right ends. The upper cover 501 is divided into a rear cover 501a and an upper cover 501b, and each is fastened and fixed by bolts and nuts. Similarly, the rear side cover 501a is fastened and fixed to the cover support frames 207 to 212 by bolts and nuts. The side covers 502 and 503 are fastened and fixed to the rear cover 501a by bolts and nuts. Therefore, the upper cover 501 covers the take-up pipe 213 and the canvas 200 wound around the upper cover 501 from above, and covers the left and right outer side surfaces with the side covers 502 and 503 at both left and right ends. Since the upper cover 501 is long in the left-right width direction, a plurality of cover support frames 207 to 212 are provided at substantially intermediate positions to support the rear side cover 501a. It is like that.

  FIG. 8 is a diagram showing a detailed configuration of a guide rail with a built-in gas spring, FIG. 8 (A) is a top view of the guide rail with a built-in gas spring, and FIG. 8 (B) is a side view thereof. FIG. FIG. 9 is a diagram showing a detailed configuration of the gas spring. FIG. 10 is an enlarged view showing the vicinity of the end of FIG. FIG. 8 shows a state in which the canvas support front frame 401 is extended to the distal ends of the guide rails 301 to 303 as shown in FIG. In the figure, the gas spring 800 is indicated by a solid line, and the configuration of the guide rails 301 to 303 and the like other than this is indicated by a dotted line. The guide rails 301 to 303 are attached to a frame such as a terrace of a building such as a store or a residential house.

  The gas spring 800 has a mechanism in which high pressure gas and oil are sealed in a sealed cylinder tube 801 and a load is generated by pushing a piston rod 802 protruding from one end thereof. In this embodiment, guide rollers 901 to 904 for guiding the wire 900 are provided at the ends of the cylinder tube 801 and the piston rod 802 of the gas spring 800, respectively. The guide rollers 901 and 903 are provided at the end of the cylinder tube 801, and the guide rollers 902 and 904 are provided at the end of the piston rod 802, respectively. One end of the wire 900 is wound and connected to the rod portion of the connection member 905. The connection member 905 and the moving frame bodies 402 to 404 are coupled with bolts and nuts via slits provided on the side surfaces of the guide rails 301 to 303.

  The wire 900 connected to the connection member 905 is reversely guided as a wire 900 a that goes to the guide roller 902 via the guide roller 901. In the guide roller 902, the wire 900 a is reversely guided as a wire 900 b toward the guide roller 903. In the guide roller 903, the wire 900 b is reversely guided as a wire 900 c directed to the guide roller 904. In the guide roller 904, the wire 900 c is reversely guided as a wire 900 d toward the wire holding unit 906. That is, the wire 900 is sequentially reversed and guided by the guide rollers 901 to 904 and connected to the wire holding unit 906. Therefore, when the canvas 200 is wound around the winding pipe 213 by the rotation motor, the canvas supporting front frame 401, that is, the connecting member 905 moves from the guide roller 901 toward the guide rollers 902 and 904. As the wire 900 is pulled along with this movement, the piston rod 802 of the gas spring 800 is pushed into the cylinder tube 801. The amount pushed in at this time is a length corresponding to about one-fourth of the moving amount of the connecting member 905. Accordingly, as shown in the figure, if the amount of the gas spring 800 to be pushed is about one third of the length of the guide rails 301 to 303, the canvas 200 is sufficiently moved along the guide rails 301 to 303. be able to.

  FIG. 11 is an enlarged view showing the relationship between the canvas support front frame, the moving frame, and the guide rail. FIG. 11A is an enlarged view of a part of FIG. 8A, and FIG. 11B is an enlarged view of a part of FIG. 8B. 11A and 11B, the cover 401a and the moving frame body 402 provided on the left and right of the canvas support front frame 401 are indicated by dotted lines, and in FIG. 11A, the moving frame body 402 is indicated by dotted lines. . The canvas support front frame 401 is composed of one piece having a first cavity 401c and a second cavity 401d. The moving frame body 402 is coupled to the connection member 905 with bolts and nuts via slits provided on the side surfaces of the guide rails 301 to 303. On the canvas side of the canvas support front frame 401, a holding portion 434 that holds the canvas 200 by inserting the end portion 200a of the canvas 200 is provided. As a result, the connecting member 905 moves in accordance with the movement of the canvas support front frame 401.

  When the canvas support front frame 401 moves along the guide rails 301 to 303, the installation interval and the installation angle of the guide rails 301 to 303 may not be constant. In such a case, the entire canvas supporting front frame 401 is slid along the moving frame bodies 402 to 404 in a direction substantially perpendicular to the guide rails 301 to 303. That is, the slide rod 402 a is attached to the moving frame body 402. Since the canvas support front frame 401 is provided with a cylindrical portion that can be fitted and slid by the slide rod 402a over the entire length, the installation interval and the installation angle of the guide rails 301 to 303 are constant. Even if it is not, the slide rod 402a moves in the cylindrical portion, so that it is possible to absorb the fluctuation error of the installation interval and the installation angle. A bolt rod 402b is embedded in the slide rod 402a, and the bolt rod 402b is fixed to the moving frame body 402 with a bolt 402c.

  FIG. 12 is a diagram showing a detailed configuration of the winding supports 204 to 206 attached to the attachment bracket 201. The winding supports 204 to 206 cooperate with end brackets 202 and 203 provided on both sides of the mounting bracket 201 to realize a stable winding operation of the canvas 200. 12A is a diagram showing the relationship between the winding pipe 213 and the end bracket 202, and FIG. 12B is a diagram showing the relationship between the winding supports 204 to 206 and the winding pipe 213. FIG. 12C is a diagram showing the relationship between the winding pipe 213 and the end bracket 203. 12A to 12C are views of the end bracket 203 side as viewed from the end bracket 202 side.

  As shown in FIG. 12A, the end bracket 202 is provided with a moving body 202a that slides in the horizontal direction. The end bracket 202 includes a rectangular opening 202b whose both ends are semicircular. The moving body 202a has a similar shape to the opening 202b that can slide in the opening 202b. The output shaft of the rotary motor is fixed to the moving body 202a with two bolts or the like so as not to rotate. On the other hand, as shown in FIG. 12C, the end bracket 203 is provided with an elliptical opening 203b on which the rotary shaft 213c of the winding pipe 213 can slide. In FIG. 12, a state in which the canvas 200 is wound around the winding pipe 213 is shown as a solid line as a canvas 213a, and a state in which the canvas 200 is expanded is shown as a dotted line as a canvas 213b.

  Accordingly, as shown in FIG. 12B, the winding diameter of the winding pipe 213 changes when the canvas 200 is wound around the winding pipe 213 or is rewound. At this time, since the urging force in the extending direction is always applied to the canvas 200, the winding supports 204 to 206 and the canvases 213a and 213b are always in contact with each other as shown in FIG. . For example, in the rolled-up canvas 213a, the moving body 202a and the rotating shaft 213c are in positions as shown by solid lines, but in the stretched canvas 213b, the moving body 202a and the rotating shaft 213c are in positions shown in dotted lines. Moving. This is because the winding support 204 and the outer circumferences of the canvases 213a and 213b are always in contact at the same position. Since the weight of the winding pipe 213 with the canvas 200 wound up like the canvas 213a becomes relatively large, the winding pipe 213 itself may be bent by the weight of the canvas 213a. However, as in this embodiment, the rotary shaft 213c of the take-up pipe 213 is slidable so that the outer circumferences of the canvases 213a and 213b are always in contact with the take-up support 204, as in the canvas 213a. Even when the weight of the take-up pipe 213 increases, the take-up support 204 supports the weight of the take-up pipe 213, so that the take-up pipe 213 can be prevented from bending.

  As shown in FIG. 12, the winding supports 204 to 206 have a substantially quarter circle shape along the outer periphery of the canvas 213a. The winding supports 204 to 206 include a plurality of roller members at the contact portion with the canvas 213a. The roller member rotates in contact with the canvas 213a. Thus, by making the winding supports 204 to 206 into a substantially circular shape, the rotary shaft 213c of the winding pipe 213 slides laterally as shown in FIG. 12 and the weight of the winding pipe 213 is increased. Can be more effectively supported. In addition, you may make it use a smooth sliding member for the contact part with the canvas 213a of the winding support 204-206, without providing a roller member.

  In the above-described embodiment, the case where a screen-like member such as a canvas is used as the opening / closing member means has been described. However, a net-like member or a drooping member may be used. Further, in the above-described embodiment, the case where the opening / closing body device is attached to a frame body such as a terrace of a building such as a store or a house has been described as an example. The present invention can be similarly applied to a device that uses an opening / closing body means such as a sheet-like curtain to divide the opening, or a device that includes an opening / closing body means that stretches like a conventional awning device. In the above-described embodiment, the case where the guide rollers 901 to 904 are provided at both ends of the gas spring 800 has been described, but the number of guide rollers may be appropriately determined according to the length of the guide rail. In place of the gas spring, expansion / contraction means having the same function may be used. Although the case where the gas spring is incorporated in the guide rail has been described, the gas spring may be externally attached to the guide rail instead of being incorporated. In the above-described embodiment, the case where there are three guide rails has been described. However, the number of guide rails may be one, two, or more, and can be appropriately changed according to the size of the canvas. In the above-described embodiment, the expansion / contraction means is contracted by winding up the canvas, but conversely, the expansion / contraction means may be extended when winding up the canvas. In the above-described embodiment, the case where the moving body 202a and the rotating shaft 213c move in the horizontal direction by the winding support 204 has been described. However, the moving direction of the moving body 202a and the rotating shaft 213c may be oblique or vertical. . That is, since the degree of supporting the weight varies depending on the angle at which the winding support 204 contacts the canvas 213a, the moving direction of the moving body 202a and the rotating shaft 213c is changed according to the oblique direction or the vertical direction accordingly.
