Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage device for evacuation equipment, and in particular, it is stored inside the handrail of a building's veeranda, and when in use, it is supported outside the upper part of the handrail and stored in the veeranda on the lower floor. This invention relates to a storage device that allows evacuation equipment to be extended and installed.

First, as a storage device of this type, a storage case for storing foldable or extendable evacuation equipment is stored inside the handrail of the Veeranda in an upright position approximately parallel to the handrail when not in use, and the storage case is removed when in use. The distal end of the storage case is supported by an arm pivotally attached to the base of the Veeranda, and the proximal end is locked to the handrail, and the storage case is supported in a substantially horizontal position to serve as an evacuation device. We proposed something that would extend toward the Veeranda on the lower floor.

However, in such conventional storage devices, the storage case does not always move in a constant trajectory when the storage case is lifted out from the top of the handrail, and the storage case is attached to the proximal end of the storage case. It was necessary to carefully operate the hook to ensure that it was secured to the handrail.

For this reason, in case of an emergency, evacuees who are upset and in a hurry should carry this storage case outside above the handrail.
The operation of locking the proximal end to the handrail was a heavy burden and could be a time-consuming operation. In view of the problems with the conventional storage device, the present invention has been developed so that the storage case is always kept at a constant level. In addition to drawing a trajectory so that the storage case is carried out above the handrail, when the storage case is carried out above the handrail, the upper and lower lids of the storage case are automatically opened and the evacuation equipment is set up. The present invention provides a storage device for evacuation equipment.
