Description

  The present invention relates to a roof opening and closing device that can be opened and closed according to the environment or purpose of use, such as season, weather, daytime and nighttime, sports competitions and performances, etc. The present invention relates to an opening / closing device for a roof opening suitable for opening / closing an opening formed in a roof of a large-scale building that also serves as.

  Conventionally, in large buildings such as athletic fields, baseball fields, indoor event venues, etc., those equipped with an opening / closing device that opens and closes the opening formed on the roof according to the season, weather, purpose of use etc. are known As the opening / closing device, for example, a folding opening / closing device as disclosed in Japanese Patent Publication No. 4-54028 (Patent Document 1) or the like is disclosed in Japanese Patent Application Laid-Open No. 8-53956 (Patent Document 2). Such a retractable switchgear is known.

  However, since the opening / closing device used in the conventional large building opens and closes a large opening, a wide opening / closing member is required. To fold or wind up such a wide opening / closing member, the opening / closing member is required. For example, a lightweight material such as a cloth has to be used as the material, and there are problems such as poor durability and weather resistance against wind and rain, especially poor daytime shielding.

  In addition, there is a problem that a space for holding the wound opening and closing member at the opening end formed on the roof is necessary, and when the space is disposed indoors, the aesthetic appearance is not excellent, and maintenance and repair are not easy. is there.

  Thus, as an opening / closing device that can also be used for opening and closing a large roof opening such as a stadium, for example, Japanese Patent Application Laid-Open No. 2004-3298 (Patent Document 3) and Japanese Patent Application Laid-Open No. 5-302393 (Patent Document 4) are presented. Thus, an opening / closing device that opens and closes a roof opening formed in a roof by slidably arranging a plurality of panels in the roof opening so as to expand and converge is proposed.

  Among these switchgears, for example, as shown in FIG. 15, a switchgear 1a for a roof opening described in Patent Document 4 has both ends 21a and 21a of a plurality of panels 2a stacked on each other on a roof 3a. The panel 2a which overlap | superposed by slidingly mounting these panels 2a along the guide rails 5a and 5a so that driving | running | working was fitted to the guide rails 5a and 5a formed in the opening ends 41a and 41a which the formed opening part 4a opposes. Opening and closing the opening 4a formed in the roof 3a by unfolding or converging 2a.

  Such an opening / closing device 1a opens and closes the roof opening 4a by unfolding and converging a plurality of thin-plate-like panels 2a formed of, for example, light metal or synthetic resin stacked in the vertical direction. There is no frictional resistance to open and close the entire opening and closing member as a single unit, such as a method of folding or winding up and opening a single large opening and closing member that covers the entire roof opening, and smooth opening and closing is possible. A large driving device is also unnecessary.

  However, the roof opening and closing device using the conventional panel 2a has a structure in which the shape of the roof is maintained in a state where each panel 2a is installed on the opening end of the roof opening itself, and wind or the like. In order to avoid the influence of the panel, the panel itself needs to be strong. To install it in a large roof opening especially in a large building, the thickness of the panel is increased. This means that there is a need to reinforce the processing of the panel, increase the weight, increase the price, and reinforce it by applying a large load to the roof opening. The problem arises that a large driving device is required.

  As shown in FIG. 16, an open / close device that sequentially connects a plurality of panels 2a in the open / close direction is disclosed in, for example, Japanese Patent Laid-Open No. 7-286485 (Patent Document 5). The panels 2a are not connected to each other in the vertical direction, and each panel 2a requires reinforcing means installed individually, and does not increase the load strength as a whole when the panel 2a is developed.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIGS. 1 to 12 show an embodiment in which the present invention is applied to a large building 1 that can be used for various purposes such as a stadium and various events, and is formed on a roof 11 of the building 1. The pair of opening / closing devices 2A and 2B that open and close from the center of the roof opening 12 to the both ends, these opening / closing devices 2A and 2B are arranged to face each other in the opening / closing direction with the same configuration, Here, it demonstrates in detail below mainly based on one opening-and-closing apparatus 2A.

  The opening / closing device 2A according to the present embodiment is configured such that each panel 3 is long in a state in which a plurality of long panels 3,. A pair of guide rails 4, each having guide rollers 32, 32 provided on the end portions 31, 31 on both sides in the longitudinal direction, arranged along the opening ends 13, 13 extending in the length direction of the roof opening 12 facing each other. 4 is erected on the roof opening 12 in a state of being fitted so as to be able to run.

  The overlapped panels 3 mounted so as to be slidable along the guide rails 4 and 4 are formed such that their lengths are sequentially reduced from the uppermost panel 3 to the lowermost panel 3. The end portions 31, 31 on both sides in the length direction of the panel 3 located at the uppermost position during storage are configured not to protrude from the end portions 31, 31 on both sides in the length direction of the lower panel 3. Therefore, the guide rails 4 and 4 are also advantageous in that the weight of the panel 3 itself can be suppressed without requiring complicated processing just by arranging the grooves 41 for each panel in parallel.

  In this embodiment, each panel has a shape in which the end face in the length direction is curved in a chevron shape by a thin plate-like material such as polycarbonate or light alloy. In addition, rain does not flow down and collect at the end, and strong winds pass through without resistance.

  Each panel 3 can be curved in advance. However, when a material such as polycarbonate having appropriate flexibility and elasticity is employed as in this embodiment, the panel 3 is curved. While bending the flat panel 3 that is longer than the distance between the open ends 13 and 13, the both ends 31 and 31 are bent while being pressed inward and are inserted into the guide rails 4 and 4. Therefore, it is not necessary to bend the panel 3 in advance, and when it is bent by this method, the tension is always applied to the surface of the panel 3, so that the strength is increased.

  More specifically, the stacked panels 3... 3 are expanded and converged by causing the panels 3 to individually travel along the guide rails 4 and 4, thereby converging the roof opening 12. The guide rollers 32 and 32 provided at both ends 31 and 31 of the panel 3 are formed on the guide rails 4 and 4 fixed to the roof opening 12 of the building 1. It is the structure which fits in the some groove | channel 41 arranged by the number of the said panels arranged in parallel, and runs smoothly each separately.

  In the present embodiment, each of the panels 3 has the guide 3 in a state in which the panels 3 adjacent to each other in the vertical direction are always opposed to each other at the upper and lower surfaces 33 and 34 at the end portions in the length direction. A connection structure 7 is provided that is slidably connected to each other along the rail 4 by a predetermined distance.

  In particular, in the present embodiment, the connection structure 7 for slidably connecting the panels 3 and 3 in contact with the vertical direction in the vertical direction is formed in a pair of engagements formed respectively at positions opposed to the panels 3 and 3 in contact with the vertical direction. It is comprised from the stop groove | channel holes 6 and 6 and the connection tool 8 inserted between each said locking groove | channel holes 6 and 6.

  The pair of locking groove holes 6 and 6 are a narrow groove hole 61 opened on the opposing surface side of the upper and lower panels 3 and 3 to be connected, and the width that is provided continuously in the thickness direction of the narrow groove hole 61. A locking groove 6 having a wide groove hole 62 wider than the narrow groove hole 61 and having a narrow groove hole 61 opened on the lower surface 34 of the upper panel 3 is positioned at the lower side with a T-shaped cross section. A locking slot 6 having a narrow slot 61 opened on the upper surface 33 of the panel 3 is formed into a long slot having an inverted T-shaped cross section and extending in the sliding direction of the panels 3 and 3.

  The connecting member 8 has a cylindrical shape having a diameter that can be inserted into the narrow groove hole 61, and has head portions 82 and 82 that have a disk shape that can be inserted into the wide groove portion 62 at both ends of the shaft portion 81. In the narrow groove holes 61, 61 of the pair of locking groove holes 6, 6 communicating with each other between the opposing surfaces of the panels 3, 3 where the shaft portion 81 of the connector 8 is vertically contacted. The heads 82, 82 at both ends of the shaft portion 81 are movably inserted and contacted in the vertical direction by being movably inserted into the wide groove holes 62, 62 of the pair of locking groove holes 6, 6. The panels 3 and 3 are connected to each other so as to be slidable by a predetermined distance.

  In the present embodiment, as described above, the wide groove holes 62 and 62 are opened in the upper surface 33 or the lower surface 34 as the locking groove hole 6 in consideration of the ease of mounting the connecting tool 8 and the like. The locking portion of the panels 3 and 3 in which the connecting portion 8 is easily and surely overlapped by separating the shaft portion 81 and at least one head portion 82 of the connecting portion 8 or making the shaft portion 81 separable. 6 and 6 can be inserted.

  In the present embodiment, since the engaging groove holes 6 and 6 communicating with the opposing panels 3 and 3 are formed as a connecting structure, for example, the panels 3 and 3 are passed through the engaging groove holes 6 and 6 communicating with rain. However, in this embodiment, the locking groove 6 is formed in the bent portion which is the end 31 in the length direction of the panel 3, so that rainwater is difficult to pass through. The panel 3 as a whole is a part and does not cause an overall leak, and if necessary, the depth of the locking grooves 6 and 6 is made deeper than the height of the head 82 of the connector 8. A lid (not shown) may be fitted into the gap formed by adjustment.

  The opening / closing device 2A having the above-described structure has the upper surface 33 and the upper and lower panels 3 and 3 with which the connector 8 comes into contact when the stacked panels 3... 3 are run along the guide rails 4 and 4. When the connecting tool 8 laid between the long groove-like locking grooves 6 and 6 opened on the lower surface 34 slides along the guide rails 4 and 4, it moves up and down at any sliding position. Panels 3 and 3 that are in contact with each other are connected and integrated in the vertical direction, and can be opened and closed in a stable state as well as each panel 3 in an unfolded state. It can be applied to a wide range of roof openings by increasing the overall strength and making individual panels thinner and lighter as a whole. Can cope with It is safe because it does not cause damage due to the fall of an independent panel, and provides a retractable roof that can be used with a simple structure that can be expanded and closed in a stable manner with minimal power, smooth and quiet. it can. In addition, the range of the opening and the opening position can be arbitrarily selected by considering the installation of the driving device.

  In particular, in the present embodiment, since the panels 3 and 3 stacked in the vertical direction are always connected in the vertical direction, the rigidity can be maintained even if the panel is reduced in weight, for example, as shown in FIG. It is needless to say that the thin portion 36 can be formed on the 33, and the thin portion 36 may be similarly formed on the lower surface 34 of the panel.

  In the present embodiment, the connection structure 7 is arranged in the vicinity of the traveling position, which is the both end portions 31 and 31 of each long panel 3, so that a few connection structures 7 are installed so that the panels 3 and 3 overlap each other. Although it is possible to smoothly travel along the guide rails 4 and 4 without hindrance in a state where the three members are securely connected in the vertical direction, the present invention is disposed on the facing surfaces of the panels 3 and 3 stacked on each other. The number of connecting structures 7 and the installation location are not limited, and the optimal position of the joining surface of the panels 3 and 3 in consideration of the material, size, and shape of the panel 3 as well as the installation cost and labor. The optimal number of connecting structures 7 may be installed.

  Further, in the present embodiment, as shown in FIG. 10 (a), the latching groove hole 6 formed on the upper surface 33 of the opposite panels 3 and 3 of the stacked panels 3. The locking groove 6 formed in the lower surface 34 is formed in two steps by alternately shifting in the longitudinal direction of the panel 3. Therefore, as shown in FIG. 10B, the engagement grooves 6 formed on the upper surface 33 of the panel 3 and the engagement formed on the lower surface 34 as in the case where the panels 3 are arranged at the same position in the overlapping direction. Compared with the case where the stop groove hole 6 is formed in the same position in the thickness direction, the thickness of the panel 3 can be halved to reduce the weight.

  As described above, in the present embodiment, the arrangement positions of the locking grooves 6 in the panel 3 are alternated so that the thickness is about the height of the locking grooves 6. However, as described above, Further, since the wide groove hole 62 is exposed as the locking groove hole 6 on the upper surface 33 or the lower surface 34 without forming the dovetail structure, the connecting tool 8 can be easily inserted between the locking groove holes 6 and 6. It is also very easy to repair and replace.

  11 and 12 show an example of driving means for converging and unfolding the stacked panels 3 in the present embodiment, and among the panels 3 stacked on each other, for example, FIG. For example, the rotary drive devices 9 and 9 installed in the roof opening 12 of the building 1 shown in FIGS. 1 to 4 are wound around both ends in the width direction of the panel 3 arranged at the uppermost position. One end of the ropes 91 and 91 is fixed, and the roof opening 12 is opened and closed by converging or unfolding the panels 3... 3 stacked in the vertical direction. The present invention is not limited to this, and other means (not shown) such as means capable of individually driving the panels 3 along the guide rails 4 and 4 by the driving device can be used. In each case, each panel It is also possible to form a desired opening to a desired position is moved to the roof opening 12 in a desired position.

  Moreover, in this Embodiment, since it was set as the structure opened and closed from the center part of the said roof opening part 12 using a pair of opening-and-closing apparatus 2A, 2B which has the same structure which installed the roof opening part 12 on both sides, the wide roof opening part 12 is provided. Even so, it is possible to reduce the size of the device and make the weight uniform by using an opening and closing device that is configured to overlap half the total amount of the panel 3, but one of them can be placed to open and close the entire device. A device that opens and closes by a device, and a combination of two or more switch devices can be easily installed (not shown).

  Furthermore, in this embodiment, the adjacent panels 3 and 3 are arranged by installing a brush member 37 standing downward on at least one of the long sides of the joint surfaces of the panels 3 and 3 stacked in the vertical direction. It is possible to prevent rainwater, dust, wind, etc., from entering through the gap formed between the panels without bringing the three into close contact with each other, and a protective roller in the sliding direction between the stacked panels 3 and 3 It is also possible to arrange 38 or the like to make the slide between the panels 3 and 3 smooth.

  FIG. 13 shows a different embodiment of the present invention, and the overall configuration is substantially the same as that of the previous embodiment, but a connecting structure for slidably connecting the panels 3 and 3 in contact with the vertical direction in the vertical direction. 7 is an engaging groove hole 6 and an engaging through hole 5 formed at opposing positions of the panels 3 and 3 that are in contact with the vertical direction, and a connection that is inserted between the engaging groove hole 6 and the engaging through hole 5. The locking groove hole 6 is composed of a narrow groove hole 61 opened on the opposite surface side of the upper and lower panels 3 and 3 to be connected, and a narrow groove hole provided continuously in the thickness direction of the narrow groove hole 61. A two-stage slot having a T-shaped cross section having a wider slot 62 wider than 61 and formed in a long slot extending in the sliding direction of the panel 3, and the locking through-hole 5 is an opposing surface of the other panel 3. From the small hole part 51 opened to the side and the small hole part 51 connected to the small hole part 51 in the thickness direction It is formed in the two-stage hole consisting of a wide large opening 52.

  Further, the connector 8 has an I-shaped cross section having a shaft portion 81 and heads 82, 82 at both ends thereof, as in the embodiment shown in FIGS. The head formed at one end of the shaft 81 and fitted into the narrow groove 61 of the locking groove 6 and the small hole 52 of the locking through hole 5 communicating with each other between the facing surfaces of the panels 3 and 3 in contact with each other. When the head portion 82 formed at the other end of the shaft portion 81 is inserted into the large hole portion 52 of the locking through hole 5 by inserting the portion 82 into the wide groove hole 62 of the locking groove hole 6, the vertical direction Panels 3 and 3 that are in contact with each other are connected so as to be slidable by a predetermined distance.

  In the above embodiment, the connector 8 is inserted between the locking grooves 6 formed in the opposing panels 3 and 3 so that the panels 3 and 3 slide with each other. Since the tool 8 is inserted into the locking groove hole 6 formed in one panel 3 and the locking through hole 5 formed in the other panel 3, the other panel 3 is fixed to the one panel 3. It is different in that it slides in the state where it is done.

  Further, FIG. 14 shows a further different embodiment of the present invention. Unlike the above-described embodiment, the panel 3 is a triangle instead of a rectangle and is centered on a rotation axis 39 arranged at the apex. Since the panels 3... 3 develop and converge in a circular shape, they can be applied to the circular roof opening 12.
