Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a sunshade device, and mainly relates to a roll-up type sunshade sheet with a movable front descending sheet attached to the front part.

(Prior Art) Conventionally, as this type of sunshade device, for example, the structure described in Japanese Utility Model Application Publication No. 59-71825 is known. In this structure, both ends of the front downward sheet winding shaft are rotatably mounted on bearing bodies in the front frame fixed to the unwinding end of the sunshade sheet, and one end of the front downward sheet winding shaft A gear is fixed to the front frame, and an output shaft having a worm gear meshed with the gear is rotatably mounted on one end of the front frame via a bearing.

(Problems to be solved by the invention) According to the conventional structure described above, both ends of the front downward sheet winding shaft are supported by bearing bodies provided at both ends of the front frame. The winding shaft may bend so that the shaft center moves up and down due to changes in the amount of winding of the front sheet wound on it, making the winding and unwinding of the front sheet unsmooth. Also, if the front downward sheet winding shaft is bent, the meshing interlock between this gear and the worm gear of the output shaft that interlocks this gear may be impaired. Since the gear on the shaft and the worm gear on the output shaft are attached at different locations, there is a problem that it is not easy to position the gears for meshing with each other.

Therefore, the present invention was developed in view of these points, and is designed to prevent the front descending sheet winding shaft from being bent due to changes in the winding amount of the front descending sheet, and to prevent the winding of the front descending sheet from being bent. It is an object of the present invention to enable smooth rewinding and rewinding at all times, and to easily set and interlock the front downward sheet winding shaft.

Then, the front descending sheet 19 is rewound from the guide port 16 of the front frame 10 and lowered by a predetermined amount with respect to the front frame 10, so that the front descending sheet 19 can be easily adjusted to descend to a length according to the sunlight. be done.

In addition, when raising the front descending seat 19, when the operating section 36 of the front descending seat adjustment device 28 is rotated in the opposite direction to the above case, the output shaft 33 and the rotation shaft 30 are rotated, and the front descending seat 19 is rotated. Sheet winding shaft 18
is rotated in the direction opposite to the above case, in which the front descending sheet 19 is wound. Then, the front descending sheet 19 is wound through the guide port 16 of the front frame 10 and raised by a predetermined amount with respect to the front frame 10, so that the front descending sheet 19 can be easily adjusted upward to the length according to the sunlight. Ru.

When adjusting the elevation of the front descending sheet 19, the front descending sheet winding shaft 18 is rotatably provided within the front frame 10 without using a bearing to support the front descending sheet. Winding shaft 1
8, its entire length is the front frame 1 through the front descending seat 19.
The front descending sheet 19 is rotated in the winding direction or the unwinding direction while being supported at zero, so that the front descending sheet winding shaft 18 is rotationally supported without being bent. Furthermore, when the front descending seat 19 is moved up and down with respect to the front frame 10, the front descending seat 19 can be moved up and down by the weight bar 21 being attached to the lower end of the front descending seat 19. It is reliably and smoothly wound or unwound around the shaft 18 and raised and lowered.

[Effect of idea]

According to the present invention, the front descending sheet winding shaft is rotatably provided without being mounted on a bearing within the front frame provided at the unwinding end of the sunshade sheet. There is no bending due to changes in the winding amount of the front descending sheet, and as a result, winding and unwinding of the front descending sheet can always be performed smoothly and reliably, and at least one end of the front descending sheet winding shaft By connecting the rotating shaft of the front descending sheet adjusting device to the connecting portion of the front descending sheet adjustment device, it is possible to easily interlock this with the front descending sheet winding shaft without having to position the device to connect them. It is possible to provide an easy-to-handle sunshading device in which the front descending seat adjustment device can be easily set, and the front descending seat, which is raised and lowered depending on the sunlight, can be easily adjusted in elevation. .
