For example, the blade 30 is perpendicular to the direction in which the first and second truss frames 11 and 12 extend (hereinafter referred to as 'first direction (arrow D1)') with respect to the horizontal plane of the truss 10. It may extend long in a direction (hereinafter referred to as 'second direction (arrow D2)'), and both ends along the second direction (arrow D2) each extend in the first direction (arrow D2) with respect to the axis extending in the second direction (arrow D2). And it can be rotatably coupled to the second truss frames 11 and 12, and a plurality of them can be arranged at predetermined intervals in the first direction (arrow D1).

(See FIG. 5), when the blade 30 is erected, the roof may be open (see FIG. 4), and when the blade 30 is laid down, the roof may be closed or closed (see FIG. 5).

The plurality of blades 30 are interlocked by a predetermined link 40, so that the plurality of blades 30 can be interlocked and rotated as one. The link 40 extends long along a first direction (arrow D1) and can be combined with a plurality of blades 30, and each of the plurality of blades 30 can rotate about an axis in the second direction (arrow D2). can be combined easily.

The actuator 50 operates in conjunction with the cylinder units 51 and 52, the piston rod 54 that moves linearly and reciprocates by the cylinder units 51 and 52, and the piston rod 54 that moves linearly and reciprocates to operate the blade 30. ) may include a connecting rod 55 that connects it so that it can rotate.

The cylinder units 51 and 52 include, for example, a cylinder 51 in which the piston rod 54 is coupled to enable straight movement and receives or releases operating force in the direction of movement of the piston rod 54, and the cylinder 51. It may include a driving unit 52 that drives the operating force to be supplied or released. The operating force of the cylinder units 51 and 52 may be pneumatic, hydraulic, or electric power. The cylinder 51 and the driving unit 52 may be arranged in a line in the direction of movement of the piston rod 54 or may be arranged side by side.

In particular, the cylinder units 51 and 52 may be disposed below the plurality of blades 30 and horizontally with respect to the first direction (arrow D1). That is, the cylinder 51 is disposed long in the first direction (arrow D1), so that the operating force of the cylinder units 51 and 52 can be applied in the first direction (arrow D1). The driving unit 52 disposed in parallel with the cylinder 51 may be disposed on the lower side of the cylinder 51 so as not to structurally interfere with the blade 30 or the like. The piston rod 54 is coupled to the cylinder units 51 and 52, that is, the cylinder 51, in a line along the first direction (arrow D1), and moves in the first direction (by the operating force of the cylinder units 51 and 52). You can move straight and round along arrow D1). One end of the connecting rod 55 is rotatably coupled to the link 40 or at least one blade 30 about an axis in the second direction (arrow D2), and the other end of the connecting rod 55 is connected to the piston rod 54. ) may be rotatably connected to the side about the axis of the second direction (arrow D2).

In addition, the actuator 50 includes a block 56 coupled to one side of the piston rod 54 and extended in a direction perpendicular to the first direction (arrow D1) with respect to the piston rod 54, and the block 56. It may further include a casing 57 that accommodates and defines a guide path 57a extending in the first direction (arrow D1). In particular, the block 56 may have a polygonal shape with multiple sides in the first direction (arrow D1), and may form a guideway 57a corresponding to the polygonal shape of the block 56. For example, but not necessarily limited thereto, the block 56 may have a rectangular shape as shown. A fitting hole 56a is formed in the block 56 into which the piston rod 54 is inserted in the first direction (arrow D1), so that it can be integrally coupled with the piston rod 54. Accordingly, both ends of the piston rod 54 in the first direction (arrow D1) are supported by the cylinder units 51 and 52 and the block 56, and can be moved straight and reciprocated only in the first direction (arrow D1) without shaking. You can. Additionally, with the roof open, the blade 30 can be supported without being rattled by the wind due to the friction between the block 56 and the casing 57.

The block 56 is preferably made of a material that is easy to process and has high wear resistance. The block 56 may be made of synthetic resin, and preferably, may be made of acetal. Acetal is a material that not only has good dimensional stability and is easy to cut, but also has high strength and rigidity. It has a low coefficient of friction, good wear resistance, and low moisture absorption, so it has the advantage that its physical properties are consistently corrected even in a humid environment.

One end of the casing 57 on the cylinder 51 side in the first direction (arrow D1) is connected to the end of the cylinder 51, and can accommodate the piston rod 54 together with the block 56.

The casing 57 is in communication with a guideway 57a on one of the circumferential surfaces in the first direction (arrow D1), and extends long in the first direction (arrow D1) corresponding to the straight-line movement distance of the piston rod 54. An opening 57b may be formed. The other end of the connecting rod 55 is rotatably coupled to the block 56 through the opening 57b about an axis in the second direction (arrow D2), so that the connecting rod 55 is linked with the piston rod 54. It may move straight in the first direction (arrow D1) and rotate about the axis of the second direction (arrow D2) with respect to the piston rod 54. In particular, an opening 57b is formed on one side of the blade 30 among the two surfaces of the casing 57 facing in the second direction (arrow D2), and penetrates the opening 57b in the second direction (arrow D2). The connecting rod 55 may be coupled to the block 56 by an extending hinge pin 58 . Both ends of the opening 57b in the first direction (arrow D1) may have a closed structure. The hinge pin 58 may pass through the through hole 56b formed in the block 56 and be inserted into the fastener 54a of the piston rod 54.

Meanwhile, the connecting rod 55 and the link 40 are based on the rotation center 30a of the blade 30 with respect to the width direction of the blade 30 extending in a direction perpendicular to the second direction (arrow D2). They can be coupled to opposite sides and moved without interfering with each other. In this case, the connecting rod 55 can be coupled with at least one blade 30. In particular, when the blade 30 is erected, the link 40 is coupled to one end of the blade 30 located above the rotation center 30a of the blade 30, and is disposed on the lower side of the blade 30. The connecting rod 55 may be coupled to the other end of the blade 30 located lower than the rotation center 30a of the blade 30.

In addition, the connecting rod 55 is disposed long in the first direction (arrow D1) opposite to the cylinder units 51 and 52 with respect to the piston rod 54, and rotates so that the blade 30 can be erected or laid down. Depending on the operation, it can be laid down or erect with respect to the piston rod 54. That is, when the piston rod 54 moves toward the cylinder units 51 and 52 in the first direction (arrow D1), the connecting rod 55 rotates downward and lies down with respect to the piston rod 54 and the blade 30 is pulled in the direction of movement of the piston rod 54, the blade 30 is erected, and the roof can be opened (see FIG. 4). Alternatively, when the piston rod 54 moves toward the opposite side of the cylinder units 51 and 52 in the first direction (arrow D1), the connecting rod 55 rotates upward with respect to the piston rod 54 and stands erect, thereby forming the blade 30. may be pushed in the direction of movement of the piston rod 54, and the blade 30 is laid down so that the roof is closed (see Figure 5). In this way, in the case of a structure in which the connecting rod 55 is laid down when the blade 30 is in an upright state, the blade 30 and the actuator 50 can be effectively placed close to each other without interfering with each other, and respond to the opening and closing of the roof. A sufficient range of rotational motion of the connecting rod 55 can be secured. In addition, when the connecting rod 55 is laid down with the roof open, it is less affected by the wind passing between the blades 30, and the blades 30 can be supported so that they are not rattled by the wind.

The actuator 50 described above may be supported by a bracket 60. The bracket 60 may be disposed on the inner side of the truss frames 11 and 12 so that the actuator 50 can be hidden and protected by the roof. The bracket 60 extends long in the first direction (arrow D1) corresponding to the actuator 50 that is disposed long in the first direction (arrow D1), so that the actuator 50 can be firmly supported.

One side of the bracket 60 may be provided with a coupling portion 61 that protrudes in the second direction (arrow D2) to which the cylinder units 51 and 52 are coupled. For example, the coupling portion 61 may be formed in the form of a panel, and a fastener penetrating in the first direction (arrow D1) may be formed. At one end of the cylinder 51 opposite to the piston rod 54 side, a nut 51b extends in the first direction (arrow D1) and penetrates the fastener of the coupling part 61, so as not to be separated from the coupling part 61. ) may be provided with a bolt portion (51a) to which the bolt is fastened. The casing 57 of the actuator 50 may be placed and fixed on the other side of the bracket 60 spaced apart from the coupling portion 61 in the first direction (arrow D1). As the actuator 50 is integrally placed on the bracket 60, it can be modularized.

In addition, the casing 57 forms a guide path 57a whose one side facing the bracket 60 is open, and the open side of the guide path 57a can be covered by the bracket 60. An opening 57b may be formed on the other side of the casing 57 opposite to the open side of the guideway 57a in the second direction (arrow D2). In addition, since the connecting rod 55 is laid approximately horizontally when the roof is open, it can be less affected by the wind passing between the blades 30, thereby preventing the blades 30 from shaking due to the wind. can do.

Meanwhile, the truss frames 11 and 12 may be provided with a rainwater gutter 16 disposed lower than the blade 30. In rainy weather, rainwater flowing on the surface of the blade (30) collects in the rainwater catchment (16), and the actuator (50) does not prevent the rainwater from collecting in the rainwater catchment (16) and also collects the rainwater collected in the rainwater catchment (16). To avoid being affected, the bracket 60 may be placed at a predetermined height above the bottom of the rainwater gutter 16. The rainwater catcher 16 has a roughly L-shaped cross-section and can extend long in the longitudinal direction of the truss frames 11 and 12, and forms a groove in which rainwater collects between the trusses frames 11 and 12. You can.

In the case of the above configuration, especially referring to FIG. 4, when the piston rod 54 is moved toward the cylinder units 51 and 52 by the operating force of the cylinder units 51 and 52, the connecting rod 55 moves downward. Rotated, the blade 30 is rotated in one direction and stands approximately horizontally, and the roof can be opened. Or, especially referring to Figure 5, when the piston rod 54 is moved to the opposite side of the cylinder units 51 and 52 by the operating force of the cylinder units 51 and 52, the connecting rod 55 rotates upward, and the blade ( 30) is rotated in the other direction and laid approximately horizontally, and the roof can be closed.
