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.

(Prior Art) Conventionally, as this type of sunshade device, for example, the structure described in Japanese Utility Model Application Publication No. 59-71827 is known. In this structure, a support arm that supports a sunshade sheet is rotatably attached to a horizontally suspended support member via a joint pipe, and the tip of a threaded rod that is screwed into the joint pipe so that it can move forward and backward is attached to the support arm that supports the sunshade sheet. Engaged with the stopper of the member, the joint pipe is rotated relative to the support member by the forward and backward movement of the rotation operation of this threaded rod, and the inclination angle of the sunshade sheet is adjusted via the support arm attached to the joint pipe. It has a structure that allows

(Problem to be solved by the invention) According to the structure described in the above publication, the inclination angle of the sunshade sheet is maintained by the screwing amount of the threaded rod and the own weight of the sunshade sheet. Therefore, the rotation of the support arm of this sunshade sheet is locked from below by a threaded rod and a stopper, but it is not locked from above, so the sunshade sheet is protected from strong winds from below. There is a problem in that there is a risk that it will rotate upward if it is received, making it unstable, and that the stopper and the threaded rod attachment part may be damaged due to the upward and downward stirring motion.

Therefore, the present invention was developed in view of these points, and it allows the sunshade sheet to be held stably at a set inclination angle, and also sufficiently responds to the fanning action caused by the wind. It is an object of the present invention to provide a sunshade device in which the inclination angle of a seat can be easily adjusted.

[Effect of idea]

According to the present invention, a movable horizontal rod having a support arm for tensioning and supporting a sunshade sheet is rotatably suspended between left and right brackets, and the movable horizontal rod is rotatably operated by a seat adjustment device. Because of this, the sunshade sheet can be easily set to the desired inclination angle, and after installation, the sunshade sheet can be held stably and securely at the set inclination angle, and the sunshade sheet can be easily set to the desired inclination angle. Even in the event that the sunshade sheet is moved and stirred, the movable horizontal rod is held securely by the seat adjustment device, and the sunshade sheet does not rotate, so it can reliably and adequately respond to the shaking motion. , and the holding portion will not be damaged. Furthermore, by operating the seat adjustment device, the inclination angle of the sunshade seat can be easily variably adjusted depending on the sunlight. Therefore, it is possible to provide a highly practical sunshade device that has excellent operability and can easily adjust the inclination angle of the sunshade sheet after installation.
