Problems solved by technology

However, since the lock pawl protrudes toward the guide groove in this structure, when the gate curtain is swung by strong wind and subjected to surface pressure, there is a bad situation in which the lock pawl engages with the buckle during the switch of the rolling gate and cannot be switched. , if the gate curtain is not processed, there is a disadvantage that the lifting of the locked gate cannot be prevented, and the prevention effect cannot be ensured.

Embodiment 1

[0097] Embodiments of the present invention will be described in detail based on the drawings. figure 1 Among them, 1 is a rolling shutter device installed at the opening of the building. The rolling shutter device 1 is structured as follows. On a reel (not shown) in the shutter box 2 provided at the upper part of the opening, the rolling shutter device is wound in the vertical direction. The gate curtain 4 formed by flexibly connecting a plurality of slats 3a, 3a... and 3b, 3b... is separated from and opposite to the guide rails 5, 5 erected on the left and right sides of the opening of the building. The two ends of the gate curtain 4 are embedded in the guide groove 8 formed on the front 7, 7 to switch the opening of the building. When the seat plate 6 at the bottom of the gate curtain 4 touches the floor in the fully closed position, The lower limit switch not shown in the figure is switched to the blocking action, thus, the repeated rotation of the reel is stopped. All th...

Embodiment 2

[0106] Next, in the above-mentioned Embodiment 1, the cover body 11 is formed from an elastically deformable metal plate such that the front end surface 11d of the front end side excess length portion 11c is in contact with the inner surface of the roof inner sheet 5b provided on the guide rail 5. The detection switch 12 is contacted to detect the lifting of the seat plate 6, but it can also be the following structure, as shown in Figure 7 (a), by bending the plastically deformed metal plate into the same shape as the above-mentioned embodiment 1, the cover body 11 is formed ', the detection part 12' is arranged inside it, as shown in figure (b), when the above-mentioned cover body 11' is pressed against the interlocking part 3b' of the slat 3b located directly above the seat plate 6, the cover body is used 11' presses and deforms the detection part 12' toward the plastic deformation of the inner side B of the house, and detects the lifting of the seat plate 6 of the gate curta...

Embodiment 3

[0109] refer to Figure 8 Example 3 will be described. Figure 8 The left picture of image 3 correspond, Figure 8 The right picture of Figure 6 Correspondingly, the same reference numerals are used for the same constituent elements, and the above description can be referred to for the constituent elements with the same reference numerals. Figure 8 The figure on the left is a figure showing the lower end of the shutter curtain with the opening fully closed. A guide groove 8 of the guide rail 5 is formed between the roof outer surface 7 a and the roof inner surface 7 b constituting the front surface of the guide rail 5 .

[0110] On the inner side surface 7b, an inner side notch recess 90 is formed upward from a portion located on the upper end side of the seat plate 6 of the shutter curtain 4 in a fully closed state, and the horizontal upper end edge 900 of the inner side notch recess 90 constitutes snap part. In the fully closed state, the lower end edge 901 of the i...

Abstract

A shutter curtain lifting prevention structure capable of securing a crime prevention effect by preventing a shutter curtain keeping a fully closed state from being raised even if the shutter curtain is attempted to be forcibly raised from the lower side of a seat plate by using a tool such as a bar. A cutout recessed part (9) is integrally formed in the guide groove (8) of a guide rail (5) by horizontally cutting the indoor side-face part (7b) of a front surface (7) positioned near a floor surface (10) in the vertical direction. Thus, when the seat plate (6) of the shutter curtain (4) keeping the fully closed state is raised, an interlock part (3b) positioned just above the seat plate (6) and bent is locked to the cutout recessed part (9).

Description

technical field [0001] The present invention relates to a mechanism for preventing the lifting of the curtain of a gate. Specifically, it relates to a mechanism for preventing the lifting of a rolling gate. For a rolling gate in a locked state, even if a tool is used to forcibly lift the gate curtain from the gap between the floor and the seat plate from the outside, the lifting of the rolling gate The prevention mechanism can also prevent the opening of the shutter curtain, so the preventive effect of the rolling shutter can be ensured. Background technique [0002] Among such rolling shutters, there is a distinction between a heavy rolling shutter and a lightweight rolling shutter. In addition, it is divided into an electric rolling shutter and a manual rolling shutter according to the presence or absence of a driving device. However, the biggest mission of the rolling gate is to keep the locked state and ensure the preventive effect. [0003] Therefore, the proposal has ...
