Description

[Detailed Description of the Invention] The present invention relates to a seat plate structure for a building shutter such as a window shutter installed in a building.

Generally, a seat plate is installed at the bottom end of the shutter curtain that constitutes this type of building shutter, but conventionally, the seat plate was a blind one piece, so it was not possible to let in light or ventilate. . Therefore, some shutter curtains are equipped with slats with windows so that the window can be opened or closed depending on the amount that the shutter curtain is lowered. This will block the window on the seat board side, and for example, if you try to ventilate it, the natural convection of air that tries to bring in fresh outdoor air from the bottom side of the opening will be blocked. There is a drawback. Therefore, it was devised to attach a movable seat plate with a window to a fixed seat plate so that it can move up and down.In this case, it is recommended to provide a stopper on the fixed seat plate that comes into contact with the magnifying part when the shutter curtain is rolled up. In order to prevent the movable seat plate from hanging down from the fixed seat plate during the above-mentioned shutter curtain winding, which would result in an unstable situation, it was necessary to use a special method with a large swallowing width in order to hide the drooping movable seat plate. There is a new drawback that it has to be made into a magsa part, which poses a problem.

The present invention was devised in view of the above-mentioned circumstances with the purpose of providing a seat plate structure for a building shutter that can eliminate these drawbacks. Therefore, the present invention is a seat plate provided at the lowermost end of a shutter curtain, and the seat plate is
A fixed seat plate is connected to the shutter curtain and is provided with a stopper that comes into contact with the magnet when the shutter curtain is rolled up, and a window is opened, which overlaps the fixed seat plate with a lowered position that allows ventilation and lighting from the window. A movable seat plate is provided that is movable up and down with respect to a fixed seat plate so that the window can change into an upward moving position where the window is closed, and a movable seat plate is provided between the fixed seat plate and the movable seat plate. This device is characterized by being provided with a locking mechanism that can lock the seat plate in the upward movement position.

With this structure, even if the seat board is composed of a fixed seat board and a movable seat board with a window to allow natural lighting and ventilation, it is possible to move the seat board when winding up the shutter curtain. The seat plate can be wound up in a state where it overlaps the fixed seat plate, and unstable drooping of the movable seat plate can be prevented.

Next, embodiments of the present invention will be described based on the drawings. In the drawing, the shutter curtain S is configured to be opened and closed vertically by being guided by guide rails 1 at both ends. The shutter curtain S in the open state is wound up and stored within a shutter case 2 which also serves as an upper eave. 3 is a window sash, and 4 is a draining board, both of which are constructed in the conventional manner.

Reference numeral 5 denotes a fixed seat plate, and the upper end of the fixed seat plate 5 is connected to the slat at the lowermost end of the shutter curtain S in a continuous manner by an interlock connection. A movable seat plate 6 disposed on the indoor side is provided on the fixed seat plate 5 so as to be movable by sliding up and down, as will be described later. Reference numeral 7 indicates a fitting groove for the lock lever a provided on the back surface of the upper part of the fixed seat plate 5, and reference numeral 8 indicates an upward facing groove provided on the fixed seat plate so as to engage the downward engaging groove 9 provided on the upper part of the movable seat plate 6. This is an engagement groove. Further, the movable seat plate 6 has a plurality of windows 10 formed in the shape of small holes in its body, and a bottom portion 11 that comes into contact with the drain plate 4 is provided at the lower end. 1
Reference numeral 2 denotes a hook, and the hook 12 is attached to the lock lever a, and is removable from a protrusion 12a fixed to the movable seat plate 6. When this hook is removed, the movable seat plate 6 is attached to the fixed seat plate 5. The locking mechanism is configured to be able to slide vertically against the locking mechanism of the present invention. Here, when the lock lever a is shifted laterally to lock the lock, the hook 12 moves laterally, but is set so as not to come off the protrusion 12a.

When the hook 12 is removed from the protrusion 12a,
The movable seat plate 6 is configured to be able to slide up and down in the following manner. That is, vertical elongated holes 15 are bored at both ends of the movable seat plate 6, and elongated bolts 14 are slidably passed through the elongated holes 15. This long bolt 14 is installed so as to pass through the fixed seat plate, and the long bolt 14 that has passed through is provided with a stopper for steadying on the outdoor side, which is located in a position close to the guide rail 1. 13 is integrally supported and fixed, and by interfering with the guide rail 1, this stopper 13 prevents the shutter curtain S from moving in the lateral direction, and when the shutter curtain S is rolled up. By colliding with the magnifying portion of the shutter case, the shutter curtain S is prevented from being caught abnormally. When the hook 12 is disengaged from the protrusion 12a, the movable seat plate 6 will fall under its own weight with respect to the fixed seat plate 5, and in this state, the shutter curtain S will be moved from the movable seat plate 6. When the movable seat plate 6 is stopped at the position where it just contacts the draining plate 4 in the lowered state, the seat plate is closed in a state allowing ventilation and sunlight. When the shutter curtain S is further lowered from this state to the lowest position, the movable seat plate 6 moves upward relative to the fixed seat plate 5, and both seat plates 5,
6 is a window 10 provided in the movable seat plate 6 in a superimposed state.
is closed, and the hook 12 automatically engages with the protrusion 12a. Note that the guide rail 1 has a latch that is locked by a locking lever a, corresponding to the state in which the movable seat plate 6 is lowered relative to the fixed seat plate 5, and the state in which both seat plates 5 and 6 are overlapped. A hook (not shown) is provided so that the lock can be locked in any of the above cases.

In the embodiment of the present invention configured as described above, when the hook 12 is engaged with the protrusion 12a, the movable seat plate 6 is in a state overlapping the fixed seat plate 5, and the window 10 of the movable seat plate 6 However, if the hook 12 is removed from the protrusion 12a and the movable seat plate 6 is lowered by its own weight, ventilation and light can be obtained from the window 10 even when the shutter curtain S is fully closed. become.

In this way, in the present invention, even if the shutter curtain S is in the fully closed state, when the movable seat plate 6 is lowered relative to the fixed seat plate 5, the window 10 provided on the movable seat plate 6 cannot be opened. This will allow for ventilation and lighting. In this case, since the ventilation and lighting is from the bottom of the opening, fresh outside air enters indoors as a natural convection, and effective ventilation and lighting can be achieved even if the opening area is small. Become.

On the other hand, when winding up the shutter curtain,
The stopper 13 that comes into contact with the magsa part is the movable seat plate 6
It is integrally fixed to the fixed seat plate 5 on the outdoor side opposite to the above. Therefore, the stopper 13 is connected to the movable seat plate 6.
In addition to not interfering with the vertical movement of the stopper 13 in any way, it has a strong fixing structure, and even if the stopper 13 collides with the magnification part, it will be reliably stopped and held without becoming unstable at all. Furthermore, in this case, if the movable seat plate 6 is locked in the upward movement position by the lock mechanism, the movable seat plate 6 will be swallowed by the magsa part together with the fixed seat plate 5. , there is no need to use a special product that increases the amount of swallowing at the magsa part to hide this problem, and a general-purpose product can be used as is. .

Furthermore, the locking mechanism of the embodiment has an automatic locking structure in which the hook 12 automatically engages with the protrusion 12a as the shutter curtain S moves, thereby locking the movable seat plate 5 in the upward movement position. When locking the movable seat plate 5 in the downward motion position to the upward motion position, there is no need to raise the movable seat plate 5 each time to lock the movable seat plate 5, and operability can be greatly improved, which is convenient. good.

In the embodiment, the long bolt 14 for attaching the stopper 13 is also used as a guide for the movable seat plate 6. Therefore, in order to make effective use of the parts, the long bolt 14 for attaching the stopper 13 is used to guide the movable seat plate 6 up and down. There is no need for additional members, and the structure can be simplified and the number of parts can be reduced at the same time.

7 to 9 show a second embodiment, in which the stopper 13 is integrally fixed to the fixed seat plate 5 by a rivet 17 while penetrating the spacer 16. However, in this case as well, the stopper 13 and the movable seat plate 6 are arranged at different positions on the inside and outside with the fixed seat plate 5 interposed therebetween, and the same effects as in the first embodiment are achieved. Moreover, in this device, the movable seat plate 6 is held in a guide groove 16a formed in a spacer 16, which serves as a fixing member for the stopper 13, so as to be movable up and down. It can be configured to serve as a guide for the movable seat plate. Furthermore, as shown in FIG. 10, when the movable seat plate 6 is brought into sliding contact with the sound deadening member 23 provided on the guide rail 1, excellent airtightness is achieved even with the movable seat plate 6. It will be secured.

In summary, since the present invention is constructed as described above, when the shutter curtain is closed with the movable seat plate lowered relative to the fixed seat plate, ventilation is provided through the window provided in the movable seat plate. Natural light is allowed to enter the room, and natural air convection occurs in the room where fresh outside air enters from the bottom of the opening, ensuring a comfortable living experience. Moreover, this item has a stopper that comes into contact with the magnifying part when winding up the shutter curtain.
Since it is installed on a fixed seat plate rather than a movable seat plate, the stopper is stabilized even though it is a seat plate that allows you to choose whether or not to provide ventilation and lighting, and is able to withstand collisions with the magsa part when winding up the shutter curtain. Become something. Furthermore, the movable seat plate can be locked in the upward movement position by a locking mechanism. Therefore, if the movable seat plate is kept in this upward movement lock state, the movable seat plate will swing around and become unstable when the shutter curtain is wound up. Even if it is a general-purpose magsa with a small amount of swallowing, the movable seat plate can be swallowed by the magsa part and hidden, so that the movable seat plate does not sag. It is possible to reliably eliminate the problems that occur when winding up the shutter curtain due to the use of the shutter curtain.
