Description

[Detailed Description of the Invention] The Kienori J has a storage section in which a cover member is stored in a non-operating position, and a state in which the moving speed of the cover member from the storage section at both ends of the width direction is equal. For example, covering members for shutters, grinders, projection screens, theatrical curtains, ball nets, insect nets, advertising banners, etc., are equipped with a synchronized feeding mechanism that displaces the covering member to an operating position. Regarding the entrance/exit device.

As for the above-mentioned conventional device, for example, a Kuwait or the like is attached to the lower end of the cover member, and the other end of the rope, whose one end is connected to the lower end of the cover member, is interlocked and connected to a synchronized payout mechanism of the winding and payout type. And displacement to working position? , Kwaito and others were used to make this happen.

However, if the lower end of the covering member comes into contact with another object or otherwise resists its displacement, the rope may become slack and the lower end of the covering member may not be displaced, or one end of the covering member in the width direction may Disadvantages include the amount of displacement being different between one side and the other end, the lower end of the cover member becoming slanted and twisted, causing unexpected damage when trying to forcibly displace it, and requiring time and effort to correct it to the desired position. was there. Furthermore, blinds and the like have the disadvantage that when a strong wind blows, the lower end of the blind may fly up and damage other objects.

In view of the above-mentioned points, it is an object of the present invention to enable the cover member to be reliably moved in and out while maintaining a predetermined posture.

In order to achieve the above-mentioned object, the present invention provides the above-mentioned cover member egress and egress device, which is provided with a guide frame for guiding the handles at both ends of the cover member in the width direction, and a While holding at least both ends of the dogs in the displacement direction,
The present invention is characterized in that it is provided with an extension mechanism that displaces the one-end side holding portion in a manner such that the distance from the other end-side holding portion is equal to each other at both ends in the width direction.

That is, at least both ends in the displacement direction of the cover member in the width direction are held by band-shaped leaf springs, chains, etc., and the leaf springs or chains on both sides are stretched and pushed and pulled in synchronization.

Therefore, even if the end of the (11) member receives resistance due to its displacement due to contact with another object, etc., if the resistance is small, it can be reliably displaced against the resistance, and the other If the resistance is large, it will not be possible to move the member carefully, and the resistance will naturally be eliminated before displacement, ensuring that the end of the now β-shaped member will be slanted due to the resistance. This can be avoided, and the cover member can now be satisfactorily displaced to the working position while reliably maintaining the predetermined position.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.
