Therefore, the umbrella 2 may be opened and lifted up even in rainy weather, so that the building unit 10 can be hung up. Since the umbrella 2 of the umbrella device 1 can be opened and closed by attaching and detaching the weight member 9, a drive source such as a motor and a cylinder is not required for opening and closing the umbrella 2, so that the structure is simple and the cost is also low. It will be less. The attachment / detachment of the weight member 9 is easy because the tip of the string-like member 39 is simply hooked on or removed from the hook 13 of the weight member 9.

A wheel 59 is attached to the tip of the auxiliary arm 57 of the umbrella 2.
When the umbrella 2 is lowered to the ground when the weight member 9 is attached or detached, the tip of the auxiliary arm 57 landed first is opened by the rotation of the wheel 59, and the tip of the string-like member 39 is lowered accordingly. It is easy to attach and detach the weight member 9. Since the umbrella 2 is opened and the balance is maintained by attaching the weight member 9, even if the umbrella 2 is accidentally contacted with an obstacle or the like during the movement in this state, the impact of the entire umbrella 2 is the contact portion. In addition to moving to the opposite side, the weight member 9 rises and is absorbed, so damage to the umbrella 2 is reduced.

When the umbrella 2 is not used, since the arm members 33 are tied together by the string 40, the respective arm members 33 do not become disjointed, which facilitates management and is safe. The chain 21 passes through the inside of the arm member 33,
Since the building unit 10 and the umbrella 2 are suspended below the same center line of the chain slinger 3, the positional relationship between the umbrella 2 and the building unit 10 does not shift, and thus the building unit 10 can be protected from rain. The auxiliary arm 57 at the tip of the arm member 33 is bent inward. Even if there is an obstacle such as a tree on the adjacent ground, the auxiliary arm 57 bends due to the pressing force of the obstacle when it comes into contact with the obstacle. Can avoid obstacles. Therefore, there is an effect that the umbrella 2 can be opened even if there is an obstacle.

The present invention is not limited to the above-mentioned embodiments, but includes the following modifications as long as the object of the present invention can be achieved. For example, although the chain sling 3 is used as the suspending member in the above embodiment, the present invention is not limited to this, and a wire sling made of a wire may be used.

Further, in the above-described embodiment, the auxiliary arm 57 is provided at the tip of the arm member 33 in order to make the tip of the arm member 33 bendable. Good. By doing this, even if there is an obstacle, if the arm member is made of an air tube if it comes into contact with this obstacle and is pushed by the obstacle, the pushed portion will bend, and if it is removed from the obstacle, the original Return to the state of. Therefore, according to such an embodiment, the same effect as the above embodiment can be obtained, the structure is simplified, and the entire device can be made lightweight.

Further, in the above-mentioned embodiment, the block-shaped iron is used as the weight member 9, but the weight member 9 is not limited to this, and may be a shot-shaped iron, and instead of iron, for example, lead, copper or the like, or concrete. It may be a weight member. In short, the weight member of the present invention may be one that can open and close the umbrella 2 by attaching and detaching it.
