Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door type louver for opening and closing a building installation port.

[0002]

2. Description of the Related Art Movable louvers in the form of a door, which are widely used for opening and closing building openings such as doors for doors of buildings, gates and windows for home use, garage doors, etc.
Are connected to each other in the height direction or the frontage direction in the vertical direction, or are assembled in a grid pattern.The angle of those blades is adjusted to block rain or sunlight, or the light source is covered to adjust the lighting. It is also used for security doors in some cases. In the case of a conventional movable louver, most of its structure is such that the rotating shafts that have passed through the entire width of each wing plate in the lateral length direction are connected by an open / close transmission member such as a rod member or a cord member such as a wire. By applying a vertical power to the, a large number of arranged blades are integrally linked in the opening and closing direction. The rotary shaft is a member that rotates the wing plate, and at the same time has the meaning of strengthening the rigidity of the wing plate against flexure in the lateral longitudinal direction. Not only increases the number of members and complicates the structure, but also increases the weight of the entire louver, and in the structure in which the opening / closing transmission member is electrically operated, a large load is imposed on the drive mechanism including a motor. It will be.

[0003]

Originally, if the wing plate has a required rigidity with respect to its structure and shape in terms of bending, it is necessary to provide a rotary shaft, which is a rotary shaft, over the entire length of the wing plate in order to reduce the rigidity. Instead, the shaft can be supported only at both ends in the longitudinal direction of the blade. It is an object of the present invention to provide a movable louver in which a wing plate has required rigidity and is lightweight, and which can be rotatably supported only at both ends in the longitudinal direction.

[0004]

In the movable louver according to the present invention, a plurality of elongated blades are rotatably supported at both longitudinal ends thereof in a height direction or a frontage direction of a building opening. The building installation port is opened and closed by applying linear power to the connecting rod that connects the blades and connects the blades to each other, and the blades are elongated hollow panel shapes. The reinforcing member is formed at both ends in the longitudinal direction, the supporting shaft pin is projected from the reinforcing member, and the supporting member is connected through the supporting shaft pin in the direction of opening and closing the building opening.

[0005]

Since the blade is formed in the shape of an elongated hollow panel, it can be provided with a required rigidity against bending and the like. Such rigidity eliminates the need for a member such as a rotating shaft over the entire length in the longitudinal direction. As a member that replaces the rotary shaft, it is sufficient to provide reinforcing portions at both ends in the longitudinal direction of the wing plate and project the support shaft pins from the reinforcing portions.

[0006]

Embodiments of the movable louver according to the present invention will be described below with reference to FIGS. As shown in Figure 1,
The movable louver 1 is configured by connecting a large number of wing plates 10 shown in FIGS. 2 and 3 in the height direction in the vertical direction so that they can be simultaneously opened and closed. Feather board 10 is front board 1 as seen from the outside
1 and the rear plate 12 are joined together in the front-rear direction to form a horizontally long internally hollow panel having a width B, and both ends of the panel length W (see FIG. 5) are reinforced side plates (reinforcement part). ) 1
It is closed at 3 and 13. Also, the panel width B of the blade 10
At the center of the shaft, the support pin 14 is inserted in the reinforcing side plate 13.
Are provided so as to project outward, and can be swung like a seesaw in the opening and closing direction with a pair of spindle pins 14, 14 projecting from both ends of the panel length as fulcrums. In other words, the opening and closing swing of the blade 10 can be performed by pivotally supporting the support shaft pins 14 at both ends on the louver support frame 2 forming the building opening.

Further, in order to support the wing plate 10 having the panel length W by the support shaft pins 14 and 14 at both ends, the reinforcing portions are formed together with the reinforcing side plates 13 and 13 at both ends, for example, reinforcement by a U-shaped cross section. The members 15 and 15 are joined together to further strengthen them. Therefore, the support shaft pin 14 is supported at two points in the longitudinal direction by the reinforcing side plate 13 and the reinforcing member 15.

Also, the front plate 11 and the rear plate 12 which are formed with the panel width B of the wing plate 10 and which form a hollow panel are bent at one end and the other end of the wing plate 10 by overlapping the ends. It has been formed (hereinafter, the end portions of the lap bending process are simply referred to as the mating end portions 17 and 18), and the spindle pin 14
By swinging in the opening / closing direction with the fulcrum as a fulcrum, one mating end 17 of the other wing plate 10 adjacent to the other mating end 18
It is designed to be able to approach and separate from each other.

In the mechanism for simultaneously opening and closing a large number of blades 10 connected by such a shape, a connecting pin 19 is provided in the vicinity of the one mating end 17 on the indoor side, for example, to connect the blades 10 together. The pins 17 are connected by one long connecting rod 3. That is, when a pushing-up force and a pushing-down force are applied to the connecting rod 3 in the vertical direction in the figure, a large number of blades 10 connected in the height direction are simultaneously swung in the opening direction and the closing direction. There is.
In the embodiment of the present invention, as shown in FIG. 4 which is a side view of a partial cross section of the device and FIG. 5 which is a rear view of the entire louver as viewed from the indoor side, a hydraulic power cylinder device is used as power for moving the connecting rod 3 up and down. 4 is used to connect the expanding and contracting piston rod 5 to the lower end of the connecting rod 3. As the power cylinder device, in addition to the hydraulic type, any type such as an air type or an electric type can be used.

With the above construction, the movable louver 1 of the embodiment operates as follows. In FIG. 4 and FIG. 5, the louver open state is indicated by reference symbol A in the upper range of the figure, and the louver closed state is indicated by reference symbol B in the lower range of the figure. For example, as indicated by reference numeral B, one mating end portion 17 of the blade 10 is
When the switch is turned on from a state in which it is in close contact with the other mating end portion 18 of the other blade 10 and is closed, the opening / closing piston rod 5 is extended obliquely upward by the operation of the power cylinder device 4, and the connecting rod 3 is drawn. Push upwards. The blades 10 connected to each other by the connecting pins 19 via the connecting rods 3 have the mating end portions 17 raised to a predetermined angle with the support shaft pins 14 as fulcrums, and the blades 10 are marked with A. To open.

When a large number of blades 10 connected in this manner are simultaneously opened and closed, each blade 10 has a hollow panel shape of the front plate 11 and the rear plate 12. There is no bending, and the support shaft pins 14 and 1 at both ends.
Since 4 is stably supported by the reinforcement by the reinforcing side plate 13 and the reinforcing member 15, it is pushed up by the connecting rod 3,
The operation of opening and closing by being pushed down is also performed smoothly.
