JPS606558Y2 - Watertight device for shutter door - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a shutter door for a building or a ship, and is particularly aimed at preventing rainwater or seawater from entering from both ends of the shutter door.

Conventionally, shutter doors installed in buildings near the coast or on ships have had to be more watertight than shutter doors installed in general buildings, and for this reason, rainwater has been removed around the shutter door, especially on both sides. A more important issue is consideration of water and seawater.

This invention solves the above-mentioned drawbacks, and by providing a tightening device that can maintain watertightness on the side end face of the shutter door, the side face of the shutter door and the inner surface of the guide rail are crimped, thereby achieving complete watertightness. It is designed so that it can be maintained.

Embodiments of the present invention will be described below based on the drawings.

In the drawing, 1 is a shutter door, 2 is a fixed guide rail that guides the shutter door 1, and the guide rail 2 is configured in parallel with a spacing member 3.
The upper end of the shutter door 1 is attached to a winding device 4 provided above , 2 .

5 is a tightening device provided between the side end surface IA of the shutter door 1 and the spacing member 3, and this tightening device 5 has a U-shaped first
The openings of a clamping frame 6 and a second clamping frame 7 are arranged opposite each other, and the first clamping frame 6 is fixed to the spacing member 3 side, and the second clamping frame 7 is fixed to the shutter door 1. It is slidably installed on the side.

A backing 8 made of, for example, neoprene rubber is attached between the side end surface IA of the shutter door 1 and the second clamping frame 7.

Reference numeral 10 denotes a notch provided in the end surface 7C of the second tightening frame 7 on the guide rail inner surface 2B side, and when the shutter door 1 is opened, the guide pin 9 and the notch 10 fit together, and the movable arm 16
It is configured such that one end thereof is lifted up and slidably engaged with the guide pin 9 at the upper end of the guide hole 19.

Reference numeral 11 denotes a connecting rod provided inside the first tightening frame 6. The connecting rod 11 is fixed to the first tightening frame 6 by a fixing plate 12, and is provided with annular joints 13 at multiple locations. .

Further, a moving arm 16 is pierced through the joint portion 13 by a shaft 14 via a collar 15 provided within the first tightening frame 6.

Reference numeral 17 denotes a shaft mounted on the second tightening frame 7, and the movable arm 16 passes through the shaft 17 via collars 18 on both sides, so that one end of the movable arm 16 is rotatable.

The R mark M17 is configured to be at a higher position than the shaft 14 when the shutter door 1 is opened, and the movable arm 16 is mounted inclined toward the connecting rod 11 side.

The moving arm 16 has a guide hole 19 in the center that slides with the guide pin 9. The waist moving arm 16 rotates around the guide pin 9, and the upper end of the moving arm 16 allows the second
The tightening frame body 7 is made movable in the direction of the shutter door 1.

Reference numeral 20 denotes a support fitting protruding from the guide rail 2, which pivotally supports a tightening arm 22 through a shaft 21, and one end of the tightening arm 22 is fixed to the fixing plate 12 through the shaft 22A with a spacing member 12A interposed therebetween. It is attached integrally with the connecting rod 11, and the other end is connected via a spring 23 to a handle 24 whose lower end is hook-shaped, and the handle 24 is locked to a stopper support member 25 via a stopper 26.

Next, the operation of the present invention will be explained.

First, when the handle 24 is manually pulled down to the stopper 26 and held there, the tightening arm 22 is pulled down by the spring 23 and lifts the connecting rod 11 using the shaft 21 as a fulcrum.

At the same time, the movable arm 16 pivotally connected to the connecting rod 11 presses the inner side 7B of the second clamping frame 7 in the direction of arrow R using the guide pin 9 passing through the guide hole 19 as a guide, and shutters the backing 8. It can be brought into close contact with the side end surface IA of the door 1 to maintain watertightness of the connection portion.

As described above, according to the watertight device of the present invention, the first clamping frame and the second clamping frame that maintain watertightness are connected by the movable arm to the side end face of the shutter door inserted into the guide rail. Then, guided by the guide hole and guide pin of the movable arm, the movable arm pushes the inner side of the second clamping frame and presses the backing fixed to the second clamping frame against the end face of the shutter door, thereby tightening the shutter door. It is possible to reliably and completely maintain the watertightness of the sides.

Furthermore, the handle is spring-loaded, making it easy to operate.

As a result of the above, it is possible to completely prevent rainwater and seawater from entering from both end faces of the shutter door, and unlike conventional shutter doors, this door has a remarkable effect on environmental protection of buildings and ships.

In addition, since each moving arm is integrally connected to the connecting rod,
Each moving arm can be operated simultaneously and integrally with the operation of the connecting rod, thereby ensuring reliable sealing.
