Problems solved by technology

[0003] In such a rolling door, when a vehicle or the like bumps into the rolling shutter by mistake during the opening and closing operation of the rolling door, it may cause deformation of the frame (pipe) and damage to the sheet.
Especially in factories and warehouses, vehicles may continue to run during the movement of roller shutters, which implies the possibility of huge shocks

Embodiment Construction

[0028] Embodiments of the present invention will be described below based on the drawings. Fig. 1 is a perspective view with a part of the rolling door device cut away, Fig. 2 is a schematic front view and a schematic side view of the rolling door device, and Fig. 3 is a front view and a side view of the rolling shutter. The rolling door box 1 is installed above an opening in a factory or the like, and a take-up roller 2 is built in the rolling door box 1, and the rolling shutter 3 is wound and mounted on the take-up roller 2 . In addition, the roller blind 3 is unwound from the take-up roller 2 or wound up on the take-up roller 2 as the take-up roller 2 rotates in the forward and reverse direction based on the opening and closing drive of the switch 19 described later. In this way, the opening and closing operation is performed between the fully closed state in which the opening is closed and the fully opened state in which the opening is opened. In addition, guide rails 4 f...

Abstract

The present invention provides a rolling shutter door device. It includes rolling shutter and guideway, in which the described rolling shutter is formed from sheet material main body and several skeleton materials which are respectively arranged in the upper portion and lower portion of said sheet material main body and mutually spaced according to a certain interval. The described guideway can be used for receiving and guiding two ends of said rolling shutter. In the described rolling shutter door device at least more than one skeleton material positioned in the lower end position in several skeleton materials can be formed from skeleton material main body and free separation end portions which are respectively removable placed on the left and right two end positions of said skeleton material main body. Besides, said invention also provides the working principle of said rolling shutter door device and its concrete operation method.

Description

technical field [0001] The present invention relates to a rolling door device for opening or closing openings of buildings such as factories and warehouses by laying a rolling shutter having a flexible sheet on a framework material. Background technique [0002] Generally, in the case of opening or closing large entrances and exits of buildings with frequent access such as factories and warehouses, in the prior art, the roll-up shutter door formed by metal slats is relatively heavy as a whole. Not compatible with fast opening and closing movements. Therefore, using a roller blind formed by laying a flexible sheet between a plurality of frame materials arranged in parallel in the upper and lower sides, it is carried out along the vertical direction of the guide rails vertically installed on the left and right sides of the opening of the building. A sheet rolling door device that moves to open and close the opening of a building. [0003] In such a rolling door, when a vehic...
