PROBLEM TO BE SOLVED: To provide a sunshade device simply structured, excellent in operability, and easily switchable to various use modes for forming a cover state outside a window, a completely shaded state, and a prescribed space between a screen and a wall (window) in the completely shaded state.SOLUTION: A screen winder controlled in winding and winding-off a screen is provided in the outside upper portion of a window, and two vertical arms are provided on the left and right sides of the window, respectively, each of which rotates around its lower end side as a fulcrum in a vertical direction and is outward turned and energized at its upper end side. The lower end side of the screen is connected to upper end parts of the vertical arms. Screen delivery position movement means enables the passing position of the screen wound off from the screen winder at the upper part of the window to be outward moved from the window in a horizontal direction.

PROBLEM TO BE SOLVED: To provide a combined structural member capable of combining two members having extending directions different from each other to each other without performing welding.SOLUTION: A first frame 11 is made of aluminum or aluminum alloy and is cylindrically formed to have a pair of opposed side wall parts 11a, 11b and is extended in one direction. A fitting hole 16 and an attachment hole 17 are respectively formed on the side wall parts 11a, 11b. A second frame 13 is extended in the other direction intersecting the extending direction of the first frame 11. A joint 14 includes a body wall part 21 abutting against an outer wall surface of the side wall part 11a, a projection part 22 which is projected on the body wall part 21, is fit through the fitting hole 16 and abuts against an inner wall surface of the side wall part 11b on the circumferential part of the attachment hole 17 and a fitting part 23 which is connected with the top end part 13a in an engagement relationship of insertion and of being inserted with respect to the top end part 13a of the second frame 13. A first bolt 31 fastens the side wall part 11b and the projection part 22 and a second bolt 32 fastens the top end part 13a and the fitting part 23.
Abstract:
PROBLEM TO BE SOLVED: To provide a slope device which has excellent dispersibility of the load applied to a slope surface and is effective for reducing weight in the case in which the slope surface formed by oblique bridging is composed of a plurality of floor members.SOLUTION: The purpose of the slope device is to form the slope surface inclined from an upper step part toward a lower step part having a difference in the level in the vertical direction. The slope device has right and left side rails, which form right and left edge parts of the slope along the inclined direction of the slope surface, and a floor panel, which couples the part between the right and left side rails and forms the slope surface. The floor panel is composed of a plurality of floor members divided in the direction orthogonal to the right and left side rails. Overlapping parts mutually overlapped in the direction vertically orthogonal to the slope surface are provided between the mutually adjacent floor members. The overlapping part is formed across approximately the full length of the floor member in the right/left direction, and an elastic material is sandwiched by the overlapping parts.
