Description

[Detailed description of the invention] The present invention relates to a movable louver door (hereinafter referred to as a movable louver door, including shutters with a structure in which the louver blades rotate to open and close, grids, casement windows, etc.; also commonly referred to as a movable louver). The object of the present invention is to provide a movable louver door whose louver blades can be opened and closed easily and reliably by manual operation.

A conventional louver door is disclosed in Japanese Patent Application Laid-Open No. 121545/1983. This louver door has louver blades attached to both vertical frames, a vertical frame between them, and a horizontal frame at the top and bottom, and a connecting rod that moves up and down inside the vertical frame.The connecting lever has an operating handle on the bottom. is installed, and the connecting rod moves up and down by rotating the handle.
In conjunction with this, the louver blades are opened and closed via a cam.

However, in the above structure, the mechanism by which the rotational force of the operating handle is converted into the vertical motion force of the connecting rod is unclear, and even if the rotational force of the operating handle is transmitted to the connecting rod, there is a limit to the rotational force of the handle. Yes, if there are many louver blades and they are heavy,
In other words, it cannot be said that it is suitable for large louver doors, or when the wind is strong and the wind pressure is acting on the blades, a considerable amount of force is required to open and close the louver blades.

The present invention provides a louver door that does not cause such problems and allows the louver blades to be opened and closed very easily and reliably.

The characteristic of this is that there are louver blades inside the surrounding frame, which consists of left and right vertical frames, an upper frame, and a lower frame.
The louver blades are rotatably supported on support rods provided on the vertical frame at both ends, and are connected to an operating rod opposite to the support rod, and the lower end of the operating rod is connected to the longitudinal direction of the lower frame. It is provided along the direction and is provided so as to be rotatable up and down about a support shaft in the intermediate portion. A connector of a predetermined length is connected to one end of the connector, and an operating body provided at the middle of the longitudinal direction of the lower frame is connected to the other end of the connector. By moving left and right along the direction, the connecting tool is rotated about the support shaft, and one end of the connecting tool is actuated up and down, and at the same time, the operating rod is actuated in the up and down direction to rotate the louver blade. can be opened and closed. In this way, the present invention, which makes good use of the lever action, has a compact design and can be operated very easily and reliably at hand, making it effective even when opening and closing large louver blades.

Examples of the present invention will be described below. Fig. 1 shows a partially exploded perspective view of the essential parts of the louver door of the present invention assembled as a storm door, with support rods 1, 1 provided at both ends of the louver blades 2, and shaft holes 3 of the support rods. The louver blades 2 are rotatably supported via pins 4. The required number of louver blades 2 are arranged in the vertical direction as in the conventional case. Reference numeral 5 denotes an operating rod that is opposed to one of the support rods 1. The operating rod is configured to operate in the vertical direction, and the operating rod has a shaft hole 3 at a position above the shaft hole 3.
Correspondingly, elongated holes 6 are formed as shown in the drawings, and pin-shaped engagement protrusions 7 fixed to the louver blades 2 are loosely fitted into the elongated holes and are linked to each other. Therefore, when the operating rod 5 is moved up and down, the louver blades 2 rotate about the pins 4 as a support shaft, that is, a rotation axis. When the operating rod 5 is pushed downward, all of the louver blades 2 are opened, and when the operating rod 5 is pushed upward, all of the louver blades 2 are closed. The degree of opening of the louver blades changes depending on the degree of vertical movement of the operating rod by a method described later.

Reference numeral 8 denotes a connecting tool connected to the operating rod 5. The connecting tool has a predetermined length and is provided along the longitudinal direction of the lower frame, and one end thereof is an L-shaped connector attached to the lower end of the operating rod. It is connected to the metal fitting 5a.

Reference numeral 9 denotes an operating body connected to the other end of the connector, which is rotatably supported by the lower frame. Then, by rotating the operating body, that is, moving the grip side to side along the longitudinal direction of the lower frame, the connecting tool is attached to the intermediate support shaft (the support shaft is rotatably supported by the lower frame). ), thereby causing the one end of the connector to operate in the vertical direction, and at the same time, the operating rod also operates and the louver blades also rotate. 10 to 13 are the surrounding side frames (frames), 10 and 11 are the left and right vertical frames, 1
2 is a lower frame, and 13 is an upper frame. 14 is a drop lock.

FIG. 2 is an enlarged exploded perspective view of the main parts of each member that moves up and down the operating rod 5 shown in FIG. 1, FIG. 3 is a diagram showing how it is attached to the lower frame, and FIG. A cutout groove 5b is formed in the L-shaped fitting 5a of the operating rod 5. The connecting tool 8 has a support shaft 8b in the middle portion and engaging pins 8c and 8d at both ends, and the connecting tool 8 is rotatably supported by the support shaft 8b in the shaft hole 12a of the lower frame 12.
The engagement pin 8c engages with the notch groove 5b, and the engagement pin 8d engages with the arc-shaped engagement hole 9a of the rotating operating body 9. The engagement hole 9a is formed such that the distance between its both ends and the support shaft 9b is different, and b>a in the drawing. The operating body 9 is rotatably formed by supporting a support shaft 9b in a shaft hole 12b of the lower frame. 9c is a grip portion of the operating body, 9d is a recessed portion, and 9e is a convex portion.

FIG. 3 shows a state in which the operating rod is moving upward, that is, a state in which the louver blades are closed, and FIG. 4 shows a state in which the operating rod is moving downward, that is, a state in which the louver blades are open. In FIG. 3, the connecting device 8 is held horizontally, and in FIG. 4, the connecting device 8 is held obliquely. In this case, the rotational position of the operating body is also different between FIGS. 3 and 4. The front view shows it turning to the left, and the back view shows it turning to the right. Reference numeral 14 indicates a drop lock, and the vertical movement mechanism of the lock rod 14a has the same structure as a conventionally known one. That is, in FIG. 3, it is mounted on the lower frame. A state in which the sliding plate 14b in the lock base (not shown) is moved to the left by operation of the handle 14f is shown, and in this case, the engaging protrusion 14c is moved so as to fit into the recessed part 9d of the operating body 9. are doing. 1
4d indicates a diagonal hole, and the lock lever 14a has its engagement pin 1.
4e moves up and down along the diagonal hole, and can freely protrude and retract from the lower end of the lower frame 12.

Figure 4 shows the locking lever 1 by moving the sliding plate 14b to the right.
4a is shown dropped below the lower frame of the shutter, that is, inserted into the lock hole of the lower rail (not shown) and locked. Thus, the engagement protrusion is disposed opposite to the protrusion 9e of the operating body, and the sliding plate cannot be moved to the left because it is blocked by the protrusion 9e. In other words, if the louver blades are open, they will be locked and the shutters will not move. Reference numeral 15 denotes a stopper base 16 having an uneven shape attached to the side of the lower frame, which is a stopper pin that engages at an appropriate position in a recessed portion of the base, and is formed on the grip portion 9c. The rotational position of the operating body 9 can be adjusted by the engagement position of the stopper pin, and thus the degree to which the louver blades are opened can be adjusted.

Figures 5 and 6 show other embodiments of the mechanism for moving the operating rod up and down. Figure 5 shows the operating rod in the upper position and the louver blades are closed, and Figure 6 shows the operating rod in the lower position. It is shown moving and the louver blades are open. In this embodiment, a connecting tool 17, an operating body 1

One end 17e of the connecting tool 17 is bent into a dogleg shape, and the bent portion is formed so as to protrude more toward the lock than the operating body 18. 17b is the support shaft;
17c and 17d are engagement pins, 18a is an engagement hole, 1
8b is a support shaft, and 18c is a gripping portion. When the operating rod is in the upper position, that is, the louver blade is closed, the sliding plate moves to the left (the position indicated by the dotted line), and the notch 19c fits into the end 17e (as shown in the fifth figure). Further, when the operating rod moves downward and the louver blades are opened as shown in Figure 6, the sliding plate of the lock is obstructed by the end 17e of the connector and cannot be moved to the left. Therefore, the lock rod 19a does not move upward and remains locked. 19d is a diagonal hole,
19e is an engagement pin, and 19f is a handle.
