Description

  The present invention relates to a shutter that opens and closes an opening by rolling up and lowering a shutter curtain.

As a conventional shutter, the shutter curtain can be moved up and down along a guide rail provided on the frame body, and the shutter curtain is wound up by a winding shaft provided above the frame body and lowered to open the opening of the frame body. A shutter that opens and closes is known.
In the shutter described above, when the shutter curtain is rolled up, the shutter curtain may be overwhelmed and come off the guide rail, that is, the winding shaft may wind up the shutter curtain.
In general, the above-described prevention of winding when the shutter curtain is rolled up is directly performed by a seat plate connected to the lowermost slat of the shutter curtain, but the seat plate may not prevent the winding.
In this way, in the case of a shutter that cannot be prevented from being caught by the seat plate, as disclosed in Patent Document 1, a stopper is attached to the seat plate, and the catch is prevented by this stopper.

Japanese Utility Model Publication No. 6-5510

Since the conventional shutter described above has a stopper attached to the outdoor side surface of the seat plate, the stopper can be seen from the outside, and the appearance of the shutter is poor.
Therefore, the present applicant can prevent the rolling-in when the shutter slat is rolled up, and attach the stopper so as to protrude from the indoor side of the seat plate to the indoor side in order to obtain a shutter having a good appearance. It was proposed to prevent entrainment by contacting the upper frame of the frame.
However, in the case of the shutter as described above, when the shutter curtain is shockedly opened (that is, when the shutter is shockedly lifted), a large force is exerted on the seat plate (shutter slat) toward the outdoor side. The outer fin on the outdoor side of the guide rail is deformed toward the outdoor side, the seat plate moves toward the outdoor side by the amount of deformation of the outer fin, the stopper does not contact the upper frame, and the seat plate is Since it may be involved, it may not be possible to prevent the entrainment.

  An object of the present invention is to provide a shutter that can prevent entrainment when winding up a shutter slat, has a good appearance, and can reliably prevent entrainment even when a large force acts on the seat plate toward the outdoor side. It is to be.

The present invention is a shutter that winds up and rolls out a shutter curtain that is movable up and down along the outer vertical piece and the inner vertical piece of the guide rail provided in the frame body, and opens and closes the opening of the frame body,
The shutter curtain connects a plurality of slats up and down, and a stopper for preventing entrainment having a mounting portion and a stopper portion on a seat plate connected to the lowermost slat so that the stopper portion faces the indoor side. attachment,
When the shutter curtain is rolled up, the stopper portion abuts against the upper frame of the frame body so as to prevent further winding of the seat plate,
The shutter is characterized in that the stopper portion is opposed to the indoor side surface of the inner vertical piece of the guide rail in the indoor / outdoor direction.

In the present invention, the seat plate has a vertical portion connected to the lowermost slat, and a horizontal portion facing the lower frame of the frame body toward the indoor side from the vertical portion,
The stopper can be a shutter that is attached to the longitudinal portion of the seat plate, and that the stopper portion is connected to the lateral portion of the seat plate so as not to move in the indoor exterior direction.
In this way, the force in the interior and exterior direction acting on the stopper portion is supported by the lateral portion of the seat plate, so that even if the stopper portion is pressed against the inner vertical piece of the guide rail with a strong force, the stopper portion is damaged. There is nothing.

In the present invention, a notch portion into which the inner vertical piece of the guide rail enters is formed at both longitudinal ends of the lateral portion,
The stoppers are respectively attached to both ends in the longitudinal direction of the seat plate, and each stopper portion is formed with a notch portion into which the inner vertical piece of the guide rail enters,
On the lower surface of each stopper, a recess is formed in which a protruding portion closer to the indoor side than the notched portion of the lateral portion is fitted, and the respective stopper portions and the lateral portion are connected so as not to move in the indoor outer direction. It can be.
In this way, the overhanging portion closer to the indoor side than the notch portion of the stopper portion contacts the indoor side surface of the inner vertical piece of the guide rail, and the overhanging portion closer to the indoor side and the lateral portion of the seat plate are outside the indoor side. Since it is connected so as not to move in the direction, the stopper portion will not be damaged even if it is pressed against the indoor side surface of the inner vertical piece of the guide rail with a strong force.

According to the present invention, the stopper portion of the stopper abuts against the upper frame, so that it can be prevented from being caught when the shutter slat is rolled up, and the appearance is good because the stopper is not visible from the outside of the shutter slat.
In addition, the stopper portion of the stopper abuts against the indoor side surface of the inner vertical piece of the guide rail, and supports the outward force acting on the seat plate also on the inner vertical piece of the guide rail. Even if force is applied, the outer vertical piece of the guide rail is not greatly deformed, the seat plate moves greatly toward the outdoor side, and the stopper portion is not closer to the outdoor side than the upper frame.
Therefore, even when a large force toward the outdoor side acts on the seat plate, the entrainment can be reliably prevented.

Stoppers 30 for preventing entrainment are attached to both ends of the seat plate 4 in the longitudinal direction.
The stopper 30 includes a mounting portion 30a and a stopper portion 30b. The stopper portion 30b faces the indoor side so that the stopper 30 cannot be seen when the shutter is viewed from the outside.
When the shutter curtain 3 is rolled up to open the opening, the stopper 30b of the stopper 30 contacts the upper frame 10 as shown by the solid line in FIG. When the shutter curtain 3 is lowered to close the opening, the seat plate 4 contacts the lower frame 11 as indicated by a virtual line in FIG.

As shown in FIG. 4, the stopper portion 30 b of the stopper 30 faces the indoor side surface 21 a of the inner vertical piece 21 of the guide rail 2 in the indoor / outdoor direction.
As a result, when a force toward the outdoor side acts on the seat plate 4, a longitudinal portion of the seat plate 4 described later contacts the outer vertical piece 20 of the guide rail 2, and the stopper portion 30 b contacts the inner vertical piece 21. The deformation allowance of the outer vertical piece 20 and the inner vertical piece 21 due to the aforementioned force toward the outdoor side is small, and even when a large force acting on the outdoor side acts on the seat plate 4, the movement allowance of the seat plate 4 toward the outdoor side is small. Since the stopper portion 30b is small and contacts the upper frame 10, it is possible to reliably prevent the seat plate 4 from being caught.

Details of the mounting portion of the stopper 30 will be described with reference to FIGS.
As shown in FIGS. 5 and 6, the seat plate 4 includes a longitudinal portion 40, a lateral portion 41 provided below the indoor side surface 40 a of the longitudinal portion 40, and an outdoor side surface 40 b of the longitudinal portion 40. A downward portion 42 provided at the lower portion is provided.
The laterally-oriented portion 41 has notches 43 that are notched at both longitudinal ends of the laterally-oriented portion 41 and are open on the longitudinal end surfaces, and the longitudinal ends are bowl-shaped.
Both ends in the longitudinal direction of the downward portion 42 are cut and removed, and the longitudinal end surface 42 a is closer to the longitudinal center than the longitudinal end surface 40 c of the longitudinal portion 40. That is, the vertical portion 40 is longer than the downward portion 42.
As a result, as shown in FIGS. 4 and 5, both longitudinal ends of the longitudinal portion 40 enter between the outer longitudinal piece 20 and the inner longitudinal piece 21 (inward recess 23) of the guide rail 2, and the notch The inner vertical piece 21 enters the portion 43, and the projecting portion 41 a closer to the indoor side than the notch 43 at the longitudinal end of the lateral portion 41 faces the indoor side surface 21 a of the inner vertical piece 21 of the guide rail 2 in the indoor and outdoor direction. And overlap in the indoor and outdoor direction.

The vertical portion 40 has a hollow portion 44 and a connecting hook 45, and has locking holes 46 at both ends in the longitudinal direction of the indoor vertical piece 44 a forming the hollow portion 44. ing. A hook 45 is connected to the lowermost slat 3a, and a seat plate 4 is connected to the slat 3a.
