Summary of the Invention

Problems to be Solved by the Invention

[0005] Although the shutter device described in Patent Document 1 has a curved portion, it does not show an L-shaped state having a corner portion where the middle part becomes substantially right-angled when fully closed.

[0006] Therefore, the corner portion formed by the curved portion is affected by the curvature of the curve and cannot effectively utilize the space.

[0007] Therefore, the problem that the present invention aims to solve is to provide an L-shaped sliding shutter device that, when fully closed, exhibits an L-shaped state with an intermediate section having a nearly right-angle corner, thereby enabling effective use of space. [Means for solving the problem]

[0008] The means for solving the problems of the present invention are as follows.

[0009] Firstly, It has multiple rectangular bodies that can be moved horizontally, each equipped with a roller at its lower end that engages with a guide rail. An L-shaped sliding shutter device characterized by connecting the rectangular bodies with hinges that allow them to be connected in series and in an L-shape. Here, "multiple rectangular bodies" refers to the multiple panels that make up the horizontally sliding shutter device. "Connectable in series" means that two adjacent rectangular objects can be connected in a straight line. "Connectable in an L-shape" means that two adjacent rectangular objects can be connected at a right angle to each other. An L-shaped horizontal shutter device is not limited to having one corner in the middle, but may have two or more corners.

[0010] Secondly, The aforementioned hinge consists of a combination of a U-shaped member and a rotating member. The U-shaped member has horizontal projections at the upper and lower ends of its vertical rear mounting surface, and the lateral length of these horizontal projections extends to the side of the adjacent rectangular body, forming an extended portion. The rotating member consists of an outer casing having a flat portion that can be attached to the side of a rectangular body, and a central shaft that is combined inside the outer casing. The L-shaped horizontal sliding shutter device according to the first description, characterized in that the central shaft of the rotating member is combined with the mounting hole of the central shaft provided in the extension piece.

[0011] Thirdly, The aforementioned hinge consists of a combination of a U-shaped member and a rotating member. The U-shaped member has horizontal projections at the upper and lower ends of its vertical rear mounting surface, and the lateral length of these horizontal projections extends to the side of the adjacent rectangular body, forming an extended portion. The rotating member consists of an outer casing having a flat portion that can be attached to the side of a rectangular body, and a central shaft that is combined inside the outer casing. The central shaft of the rotating member is combined with the mounting hole for the central shaft provided in the extension piece. The L-shaped horizontal sliding shutter device according to the first, characterized in that a notch is formed at the boundary between the horizontal projection piece and the extension piece, and the depth of the extension piece is formed to be smaller than the depth of the horizontal projection piece. [Effects of the Invention]

[0012] According to the present invention, the following effects can be achieved.

[0013] The rectangular panels that make up the horizontal sliding shutter are connected by hinges that allow two adjacent rectangular panels to be connected in series and in an L-shape. As a result, when fully closed, the intermediate section maintains a right angle, creating a corner, which allows for efficient use of space. In addition, when fully closed, the intermediate section maintains a right angle, allowing the L-shape to be stably maintained. Furthermore, even large panels can be connected using hinges that allow for both linear and L-shaped connections, enabling smooth movement along the curved sections of the guide rail.

Mode for Carrying Out the Invention

[0015] Hereinafter, the mode for carrying out the present invention will be specifically described with reference to the drawings. Here, the same members in the attached drawings are denoted by the same reference numerals, and redundant descriptions are omitted. Note that since the description here is one mode in which the present invention is implemented, the present invention is not limited to this mode.

Example

[0016] The L-shaped horizontal draw shutter device of this example is a rectangular body that can move horizontally and has four panels provided with rotatable rollers 2 at the lower end side that combine by contacting the guide rail 1 laid on the ground surface, as shown in FIGS. 1 and 2. The guide rail 1 has a bent portion that is curved in the middle.

[0017] The four panels are extracted for the purpose of explaining this example, and are composed of the first panel 3A, the second panel 3B, the third panel 3C, and the fourth panel 3D in order from the front. In this example, the first panel 3A to the third panel 3C have the same width, and the width of the fourth panel 3D is formed to be large, but all can be formed with the same width, or each can be formed with a different width. Note that when actually installing the L-shaped horizontal draw shutter device of the present invention, the number and size of the panels constituting the rectangular body can be freely determined according to the installation location.

[0018] The panel consists of panel frames 31 arranged on all four sides and a panel body 32 located inside the panel frames 31. Adjacent panels are connected at two locations, top and bottom, by hinges 4 that can connect them in a series and L-shape configuration.

[0019] In Figure 1(b) and Figure 2(b), reference numeral 5 indicates a rack attached to the lower end of each panel, and reference numeral 6 indicates a pinion that engages with the rack 5. The pinion 6 is rotatable in both clockwise and counterclockwise directions by a motor (not shown in the figure). The rotational motion of the motor acts as the means of movement, causing each panel to move. The panels can also be moved manually.

[0020] The hinge 4, which can be connected in a series and L-shape, is a combination of a U-shaped member 41 and a rotating member 42, as shown in (d) in Figure 3 and (d) in Figure 4. The U-shaped member 41 has horizontally protruding pieces 411 at the upper and lower ends of its vertical rear mounting surface 413, and the lateral length of the horizontally protruding pieces 411 extends continuously to the panel frame 31 on the side of the adjacent panel, forming an extension piece 412.

[0021] Here, the horizontal overhang 411 and the extension piece 412 are formed as a single unit, but the notch 43 formed at the boundary portion reduces the depth of the extension piece 412, and as shown in Figure 3(a), it is configured to absorb the thickness of the mounting plate 424, which will be described later. As shown in Figure 3(d), the extension piece 412 is provided with a mounting hole 412a for inserting the central shaft 422, which will be described later.

[0022] As shown in Figure 3(c), the rotating member 42 has an outer casing 421 having a mounting surface with a flat portion 421a that can be attached to the panel frame 31, which is the side of the panel, via a mounting plate 424, and a central shaft 422 that is combined inside the outer casing 421. As shown in Figure 3(b), the exterior body 421 has curved portions 421b on both sides of the flat portion 421a.

[0023] As shown in Figure 3(c), the upper and lower ends of the central shaft 422 are fixed to the extension piece 412 by tightening bolts 423. In other words, as shown in Figure 3(d), the central shaft 422 of the rotating member 42 is combined with the mounting holes 412a of the central shaft 422 provided in the upper and lower extension pieces 412 of the U-shaped member 41.

[0024] As shown in Figure 3(b), the U-shaped member 41 is directly attached to the panel frame 31 by four mounting screws 414 that utilize holes (not shown) formed near the four corners of the rear mounting surface 413. As shown in Figure 3(b), the rotating member 42 is attached to the panel frame 31 by four mounting screws 425 that utilize four holes (not shown) formed near the four corners of the mounting plate 424. Here, as shown in Figure 3(c), the flat portion 421a of the exterior body 421 is fixed to the mounting plate 424 by adhesive, welding, or the like.

[0025] Next, the operation of the L-shaped horizontal sliding shutter device described above will be explained.

[0026] When moving from fully open to fully closed, as shown in Figure 1, the pinion 6 rotates, causing the position of the rack 5 to move, and the first panel 3A, second panel 3B, third panel 3C, and fourth panel 3D advance in series from the end. When the guide rail 1 passes through a curved section, the roller 2 rotates, and the central shaft 422 of the rotating member 42 rotates to accommodate the curve.

[0027] When fully closed, as shown in Figure 2, the connection between the third panel 3C and the fourth panel 3D is bent at a 90° angle. In this case, as shown in Figure 4, the hinge 4 forms an L-shape with the panel frames 31 of adjacent panels, creating a corner and maintaining a stable state. [Explanation of symbols]
