  In Patent Document 1, since the upper end side of the drive arm is connected to the side surface of the movable frame, the force point and the action point are greatly separated in the direction orthogonal to the displacement direction of the movable frame (horizontal direction in Patent Document 1). It must be a composition.

  For this reason, there is a possibility that a large bending moment or torsional moment acts on a member that connects the force point and the action point (in Patent Document 1, a shaft for a roller). In addition, a power point is a location which exerts a force directly when the drive arm swings. The action point refers to a portion of the movable frame where a force for displacing the movable frame directly acts.

  In view of the above points, the present application discloses an example of a skylight device that can suppress generation of a large bending moment or twisting moment.

  The skylight device is a drive arm (91) for displacing the movable frame (5), and one end side thereof can swing to one of the fixed frame (3) and the movable frame (5). A drive arm (91) connected to the other frame (5) so that the other end side is movable in parallel with the other frame (5), and pressure received from the drive arm (91) when the drive arm (91) swings It is desirable to provide a pressure receiving portion (11) provided on a surface that intersects the displacement direction of the movable frame (5) in the “other frame (5)”.

  And since the pressure receiving part (11) is provided in the surface which cross | intersects the displacement direction of a movable frame (5) among "the other frame (5)", in the direction orthogonal to the displacement direction of a movable frame (5) The distance between the force point and the action point can be smaller than that in Patent Document 1. Therefore, the bending moment or the twisting moment generated due to the separation of the force point and the action point can be reduced.

Hereinafter, the link mechanism 9 according to the present embodiment will be described using the first link mechanism 9 as an example.

  The link mechanism 9 is configured by an X link mechanism having at least a drive arm 91, a guide arm 92, and the like. One end of the drive arm 91 in the longitudinal direction is assembled to the fixed frame 3 so as to be swingable.

  The other end in the longitudinal direction of the drive arm 91 is connected to the movable frame 5 so as to be swingable, and the connecting portion moves in a direction orthogonal to the moving direction of the movable frame 5 (vertical direction in the present embodiment). It is possible.

  In other words, the lower end side of the drive arm 91 is swingably connected to the fixed frame 3 in a state where the connection center position does not move with respect to the fixed frame 3. The upper end side of the drive arm 91 is swingably connected to the movable frame 5 in a state where the connection center is movable in parallel with the movable frame 5.

  The fixed frame 3 is provided with a spring (not shown) that applies an elastic force to the drive arm 91 to swing the drive arm 91. The spring increases in the amount of elastic deformation when the other longitudinal end of the drive arm 91 is swung from the open position side to the closed position side.

  For this reason, the said spring exhibits the elastic force which rock | fluctuates the longitudinal direction other end side of the drive arm 91 to the open position side. Note that the spring according to the present embodiment is a torsion bar that uses torsional deformation of an elastic body formed in a rod shape.

  A wire (not shown) is connected to the drive arm 91. The wire causes the driving arm 91 to exert a force that causes the other end in the longitudinal direction of the driving arm 91 to swing toward the closed position.

  The wire causes the force to act on the drive arm 91 when the wire is wound around a winding drum (not shown) housed in the operation section. When the winding drum lock device (not shown) is released and the winding drum is allowed to rotate, the drive arm 91 swings to the open position side by the elastic force of the spring.

  One end side in the longitudinal direction of the guide arm 92 (in this embodiment, the upper end side) is connected to the movable frame 5 so as to be swingable. The other end side in the longitudinal direction of the guide arm 92 (in this embodiment, the lower end side) is connected to the fixed frame 3 so as to be swingable, and the connecting portion moves in a direction perpendicular to the moving direction of the movable frame 5. It is possible.

  The drive arm 91 and the guide arm 92 are connected to each other so that the middle part in the longitudinal direction can swing. As shown in FIG. 4, the guide arm 92 is disposed outside the drive arm 91. The outside of the drive arm 91 refers to the side opposite to the openings 3A and 5A across the drive arm 91.

The first roller 13 </ b> A and the second roller 13 </ b> B are rolling elements provided on one end side in the longitudinal direction of the drive arm 91, that is, on the upper end side of the drive arm 91.

  The rotation center axis L1 of the first roller 13A coincides with the rotation center axis of the second roller 13B. That is, the first roller 13A and the second roller 13B are provided on the rotation center axis L1.

  The rotation center axis L <b> 1 is parallel to the swing center axis Lo of the drive arm 91. For this reason, the displacement direction of the movable frame 5 is orthogonal to the rotation center axis L1. That is, the first rail surface 11 </ b> A and the second rail surface 11 </ b> B are surfaces orthogonal to the displacement direction of the movable frame 5.

  The second roller 13B is disposed on the opposite side of the first roller 13A across the drive arm 91 in a direction parallel to the rotation center axis L1. Specifically, the first roller 13A and the second roller 13B are the same roller, and the first roller 13A and the second roller 13B are disposed at positions symmetrical with respect to the center line L2 of the drive arm 91. ing.

The surface pressure center line is a position where the area moment of contact surface pressure is balanced.

  The guide arm 92 is located on the same side as the first roller 13A with respect to the drive arm 91 in a direction parallel to the rotation center axis L1. That is, when the direction in which the movable frame 5 is displaced (the vertical direction in the present embodiment) is the displacement direction, the first roller 13A is at a position shifted in the displacement direction with respect to the guide arm 92.

  The pressure receiving portion 11 constituting the guide rail is provided with a first restriction wall 15A and a second restriction wall 15B. The first restriction wall 15A is provided on the opposite side of the drive arm 91 across the first roller 13A in a direction parallel to the rotation center axis L1.
