Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventional so-called "shutter" opening / closing devices are basically formed of steel (steel material), and ribs are formed to provide strength as a facing material. On the other hand, there is also an opening / closing device having a flat front surface in order to enhance the designability, such as the overhead door of Patent Document 1. The opening / closing body of such an opening / closing device is formed by rotatably connecting a plurality of panel bodies having flat fronts to each other, and each panel body is formed as an aluminum extrusion. According to the aluminum extrusion, since the degree of freedom in molding is high, it is possible to obtain excellent designability by making the front flat, and at the same time, to obtain strength by molding it as a three-dimensional structure having reinforcing members such as ribs. On the other hand, when forming a panel by bending sheet metal (for example, when using steel sheets to improve fire resistance), if the front side is made flat, there is a problem that the strength will be insufficient and dents may occur.

[0005] In view of the above, the present invention aims to provide an opening and closing device that includes a panel body that can obtain the necessary strength and be manufactured efficiently, even when forming a panel body with a flat front side by bending a sheet material.

Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. Note that the following embodiments are one form when embodying the present invention, and do not limit the present invention within its scope.

[0018] <Embodiment 1> FIG. 1 is a view showing an opening / closing device of an embodiment according to the present invention, and is a perspective view seen from the indoor side. The opening / closing device 100 is an opening / closing device that opens and closes an opening formed in a wall surface separating the indoor and outdoor, and more specifically, is an opening / closing device called an overhead door, an oversliding door, or the like. As shown in FIG. 1, the opening / closing device 100 includes an opening / closing body in which a plurality of panel bodies 1 are connected to each other so as to be rotatable by hinges 110 and 120 (the hinge 120 is a hinge that also has a function of holding rollers 130 at both ends in the width direction of the panel body, and the hinge 110 is a hinge provided in the middle in the width direction of the panel body). The hinges 120 at both ends in the width direction of the opening / closing body have hinge shafts made of shaft cylinders, and the shafts of the rollers 130 are held in these shaft cylinders. As a result, multiple rollers 130 are provided in the vertical direction at both ends in the width direction of the opening / closing body. Guide rails 140 are also provided on both sides of the opening to guide the movement of the rollers 130. As a result, the opening / closing body can move along the guide rails 140 between the closed state shown in Figure 1 and the open state in which the opening / closing body is in a nearly horizontal position at the top. The opening / closing device 100 also includes a drive device and its mechanism for driving the opening and closing of the opening / closing body, a control device for controlling the opening and closing operation, etc. (not shown in particular), but since the configuration of these is not directly related to the present invention, further explanation is omitted here.

[0019] Figure 2 is a cross-sectional view (a cross-sectional view taken from a plane perpendicular to the width direction of the panel body) showing the panel body 1 of this embodiment. The panel body 1 of this embodiment is A front member 11 whose front surface is formed in a flat shape, A rear surface member 12 whose rear surface is formed in a flat shape, Multiple vertical reinforcing members 13 are arranged in the width direction of the panel body 1, A pop nut PN is a fastening member that integrally fastens the front member 11, the vertical reinforcing member 13, the rear member 12, and the hinge 110 or hinge 120. It is equipped with.

[0020] Figure 3 shows the front member 11, where Figure 3(a) is a side view (partially omitted in the vertical direction) and Figure 3(b) is a rear view (partially omitted in the vertical and width directions). The front member 11 is formed by bending a steel plate such as steel or stainless steel, and has an upper end folded portion 111 on its upper end side and a lower end folded portion 112 on its lower end side. The upper folded portion 111 has interlocking protrusions 1111 and interlocking recesses 1112, so as to form an interlocking structure with the lower folded portion 112. The upper folded portion 111 also has fastening member mounting holes 111H and a rear surface portion 1113 that serves as a mounting portion for hinges and the like. Similarly, the lower end folded portion 112 has interlocking protrusions 1121 and interlocking recesses 1122 so as to form an interlocking structure with the upper end folded portion 111. It also has a rear surface portion 1123 which has fastening member mounting holes 112H and serves as a mounting portion for hinges and the like.

[0021] Figure 4 shows the rear member 12, where Figure 4(a) is a side view (partially omitted in the vertical direction) and Figure 4(b) is a rear view (partially omitted in the vertical and width directions). The rear member 12 is formed by bending a steel plate such as steel or stainless steel, and its upper and lower ends are bent towards the front at approximately right angles, giving it a roughly U-shape when viewed from the side. On the flat rear surface, fastening member mounting holes 121H are formed at positions corresponding to each fastening member mounting hole 111H of the front member 11, and fastening member mounting holes 122H are formed at positions corresponding to each fastening member mounting hole 112H of the front member 11. While the bent portions at the upper and lower ends of the rear member 12 are not strictly necessary, forming these portions is preferable because it improves the strength of the member. Furthermore, forming these portions is also preferable because it places the cut surface of the member between the joints of the panel body, reducing the risk of the user touching the cut surface (such as cutting their fingers).

[0022] Figure 5 is a perspective view showing the vertical reinforcing member 13. The vertical reinforcing members 13 are reinforcing members arranged in multiple locations in the width direction of the panel body 1. In this embodiment, a total of five vertical reinforcing members 13 are provided, one near each end of the panel body 1 and three in between. The vertical reinforcing member 13 has a basic form that is U-shaped (C-channel) when viewed from above, and on the rear side, fastening member mounting holes 131H are formed on the upper side and fastening member mounting holes 132H are formed on the lower side. Furthermore, a notch 133 is formed on the upper front side, and a notch 134 is formed on the lower front side. As can be seen from Figure 2, these are formed in a shape that follows the interlocking structure of the upper end folded portion 111 of the front member 11. The notch 134 on the lower end side has the same structure (symmetrical shape) as the one on the upper end side, so that the vertical reinforcing member 13 can be used in reverse. This allows the right and left sides of the panel body 1 to be formed at both ends using a common vertical reinforcing member 13. Note that the side parts of the panel body 1 are basically not visible to the public, so the configuration that allows the vertical reinforcing member 13 to be used in reverse is not required (either the notch 134 on the lower end side is not formed, or it is formed in a shape that follows the interlocking structure of the lower end folded portion 112 of the front member 11).

[0023] As shown in Figure 2, the panel body 1 is constructed with vertical reinforcing members 13 positioned inside the front member 11 and the rear member 12, and these three members are fastened together by pop nuts PN. More specifically, the fastening member mounting hole 131H of the vertical reinforcing member 13 is aligned to overlap with the fastening member mounting hole 111H formed in the upper end folded portion 111 of the front member 11 (and the fastening member mounting hole 121H formed in the rear member 12), and the fastening member mounting hole 132H of the vertical reinforcing member 13 is aligned to overlap with the fastening member mounting hole 112H formed in the lower end folded portion 112 of the front member 11 (and the fastening member mounting hole 122H formed in the rear member 12). The three members are then fastened together integrally by crimping pop nuts PN that are inserted through these aligned mounting holes. Furthermore, it is preferable to adhere adhesive or adhesive tape to the front and rear sides of the vertical reinforcing member 13, respectively, to bond the front member 11 to the vertical reinforcing member 13 and the rear member 12 to the vertical reinforcing member 13.

[0024] Figure 6 shows the connection portion of the panel body 1 by the hinge 120. As shown in the figure, the hinge 120 is attached by screwing bolt B into pop nut PN. Note that although the hinge 120 (in which the shaft of roller 130 is held in the shaft cylinder (roller 130 is not shown)) is shown here, the mounting structure of hinge 110 is similar. In other words, the front member 11, the vertical reinforcing member 13, the rear member 12, and the hinge 110 or hinge 120 are integrally fastened together by a set of fastening members, namely the pop nut PN (and the bolt B fastened to it).

[0025] As described above, with the opening and closing device 100 of this embodiment, since the vertical reinforcing member 13, which is a reinforcing member, is provided inside the panel body 1, even when forming a panel body with a flat front side by bending a plate material, it is possible to prevent problems such as insufficient strength causing dents or other damage. Furthermore, since the front member 11, the vertical reinforcing member 13, the rear member 12, and the hinge 110 or hinge 120 are all fastened together by a single set of fastening components, the manufacturing process can be carried out efficiently, and the consolidation and standardization of fastening components also contributes to cost reduction. Furthermore, according to the opening and closing device 100 of this embodiment, vertical reinforcing members 13 are provided at the connection portion of each hinge, and the movable portion is reinforced, thereby stabilizing the bending motion of the panel body. In addition, according to the opening and closing device 100 of this embodiment, not only the front side but also the rear side is formed flat, resulting in superior design aesthetics.

[0026] Furthermore, in order to further improve the strength of the vertical reinforcing members 13 as a frame, horizontal reinforcing members may be provided to connect each vertical reinforcing member 13 to one another. Furthermore, for the same reason, a recess or protrusion extending along the width direction of the panel body may be formed on the rear member, and an engaging portion that engages with this recess or protrusion may be formed on the vertical reinforcing member. Figure 7 shows an example of such a panel (a cross-sectional view taken with a plane perpendicular to the width direction of the panel). In the panel body 1-1 shown in Figure 7, a recess 12-11 extending along the width direction of the panel body is formed in the rear member 12-1, and an engaging portion 31-11 that engages with the recess 12-11 is formed in the vertical reinforcing member 13-1. By engaging the recess 12-11 with the engaging portion 31-11 of each vertical reinforcing member 13-1 (more preferably by bonding), the same effect as if the vertical reinforcing members were interconnected by the horizontal reinforcing members can be obtained.

[0027] <Embodiment 2> Figure 8 is a cross-sectional view (a cross-sectional view taken from a plane perpendicular to the width direction of the panel body) showing the panel body of the opening and closing device of Embodiment 2. The basic configuration of the opening and closing device in this embodiment is the same as in Embodiment 1, and the fact that the opening and closing body is formed by multiple panel bodies being connected to each other so as to be rotatable by hinges is also the same, so a detailed explanation is omitted here. Furthermore, for configurations similar to those in Embodiment 1, the same reference numerals as in Embodiment 1 are used, and their explanations here are omitted or simplified.

[0028] The panel body 1-2 of this embodiment is Front member 11 and Rear member 12 and An upper lateral reinforcing member 14-1 extending in the width direction of the panel body, A lower lateral reinforcing member 14-2 extending in the width direction of the panel body, A plurality of vertical reinforcing members are arranged in the width direction of the panel body, and a vertical reinforcing member 13-2 is joined to an upper horizontal reinforcing member 14-1 and a lower horizontal reinforcing member 14-2, A pop nut PN is a fastening member that integrally fastens the front member 11, the upper lateral reinforcing member 14-1, the rear member 12, and the hinge 110 or hinge 120, or the front member 11, the lower lateral reinforcing member 14-2, the rear member 12, and the hinge 110 or hinge 120. It is equipped with.

[0029] The front member 11 and the rear member 12 have the same configuration as in Embodiment 1, so their description is omitted here.

[0030] The upper lateral reinforcing member 14-1 extends in the width direction of the panel body and is joined to the upper end folded portion 111 of the front member 11. The lower lateral reinforcing member 14-2 extends in the width direction of the panel body and is joined to the lower end folded portion 112 of the front member 11. Furthermore, multiple vertical reinforcing members 13-2 are arranged in the width direction of the panel body, with their upper ends joined to the upper horizontal reinforcing members 14-1 and their lower ends joined to the lower horizontal reinforcing members 14-2. These elements form a lattice-like framework structure.

[0031] Figure 9 is an exploded perspective view showing a portion of the upper lateral reinforcing member 14-1, the lower lateral reinforcing member 14-2, and the vertical reinforcing member 13-2.

[0032] The upper lateral reinforcing member 14-1 is, The rear portion has fastening member mounting holes 14-1H2 formed at positions corresponding to each fastening member mounting hole 111H of the front member 11, The upper surface portion is formed so as to follow the upper surface of the interlocking protrusion 1111 of the upper end folded portion 111, The bottom surface has holes 14-1H1 formed at predetermined intervals in the width direction (at the positions where the vertical reinforcing members are placed) through which screws are inserted to fasten the upper end of the vertical reinforcing member 13-2, It comprises a front section connected to a bottom section.

[0033] The lower lateral reinforcing member 14-2 is, The rear portion has fastening member mounting holes 14-2H2 formed at positions corresponding to each fastening member mounting hole 112H of the front member 11, A bottom surface portion formed to follow the bottom surface of the interlocking projection 1121 of the lower end folded portion 112, The upper surface portion has holes 14-2H1 formed at predetermined intervals in the width direction (at the positions where the vertical reinforcing members are placed) through which screws are inserted to fasten the lower end of the vertical reinforcing member 13-2, It comprises a front section connected to a top section. As can be understood from the above explanation, the upper lateral reinforcing member 14-1 and the lower lateral reinforcing member 14-2 can also be used by reversing the same member. By using the upper lateral reinforcing member 14-1 and the lower lateral reinforcing member 14-2 as common members, it is possible to reduce costs and improve productivity.

[0034] The vertical reinforcing member 13-2 has a structure in which the top and bottom portions are joined to a member (C-channel) that is roughly U-shaped when viewed from above. The top surface has a hole 13-2H1 through which a screw for connecting to the upper lateral reinforcing member 14-1 is inserted, and the bottom surface has a hole 13-2H2 through which a screw for connecting to the lower lateral reinforcing member 14-2 is inserted. Furthermore, the vertical reinforcing member 13-2 may be provided with an additional front section. Alternatively, the front section may be formed without providing any of the side sections (by rotating the vertical reinforcing member 13-2 by 90° to form either the front section, rear section, or side section).

[0035] The assembly of panel body 1-2 begins by connecting the upper horizontal reinforcing member 14-1 and the lower horizontal reinforcing member 14-2 with multiple vertical reinforcing members 13-2 to form a lattice-like framework. In this embodiment, screws (bolts and nuts) are used as an example for connecting each member, but any fixing method such as adhesive or welding may be used. Next, the lattice-shaped frame formed above is fitted onto the front member 11, and then the rear member 12 is placed over it. At this time, the fastening member mounting holes of each member are aligned. More specifically, the fastening member mounting hole 14-1H2 of the upper horizontal reinforcing member 14-1 is aligned to overlap with the fastening member mounting hole 111H formed in the upper folded portion 111 of the front member 11 (and the fastening member mounting hole 121H formed in the rear member 12), and the fastening member mounting hole 14-2H2 of the lower horizontal reinforcing member 14-2 is aligned to overlap with the fastening member mounting hole 112H formed in the lower folded portion 112 of the front member 11 (and the fastening member mounting hole 122H formed in the rear member 12). By inserting the pop nuts PN through these aligned mounting holes and crimping them, each component is fastened together as a single unit. Although it is also possible to fasten each component with rivets instead of pop nuts PN, in this case, separate screw holes for screwing in the hinges would have to be formed, so it is preferable to use pop nuts as in this embodiment. It is preferable to bond the frame to the front member 11 and the rear member 12 (this may involve bonding the entire contact area between the members, or bonding only a portion of each member). The connection of the panel bodies 1-2 by hinges 110 and 120 is the same as described in Embodiment 1, and a set of fastening members integrally fastens the front member 11, the upper lateral reinforcing member 14-1, the rear member 12, and the hinge 110 or hinge 120, or the front member 11, the lower lateral reinforcing member 14-2, the rear member 12, and the hinge 110 or hinge 120.

[0036] As described above, according to this embodiment, the same effects as in Embodiment 1 can be obtained, and since the upper horizontal reinforcing member 14-1 and the lower horizontal reinforcing member 14-2 are connected by the vertical reinforcing member 13-2 to form the aforementioned lattice-like framework, a panel body with higher strength can be made.

[0037] The vertical reinforcing members 13-2 may be provided at the locations where the hinges are connected, as in Embodiment 1, but they may also be provided independently of the hinge positions. For example, in the opening / closing device 100 of the embodiment, five hinges are provided in the width direction, but it may be the case that there are three vertical reinforcing members 13-2.

[0038] In each embodiment, the upper and lower ends of the panel body are shown as an example of a Z-shaped interlocking structure, but the present invention is not limited to this, and any shape is possible in which a portion of the upper and lower panel bodies overlap at the joint. Depending on the difference in shape, the shape of the upper and lower ends of the vertical reinforcing members, and the shapes of the upper and lower horizontal reinforcing members can be made to match.

[0039] In each embodiment, the panel body was shown as having a front and a rear surface, but the present invention is not limited to this, and the rear surface member may be absent. [Explanation of symbols]
