Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a movable louver door with a drop lock that can be used as a storm door.

(Prior art) Movable louvers have conventionally been used in ventilation louvers for ventilation fans and elevators, but movable louver doors with locks have not been sufficiently developed.

(Problem to be solved by the invention) In a sliding door type storm door equipped with movable louver blades, if the storm door is accidentally stored in a door bag with the louver blades open, there is a risk that the louver blades will come into contact with the door bag and be damaged. Even if the blades are heated or stored, there is a risk that the blades will be damaged due to polymerization in the door bag, so it is necessary to solve this problem.

The present invention facilitates and reliably opens and closes the louver blades, and also solves the above problems.

(Means for Solving the Problems) The movable louver door of the present invention rotatably supports the louver blades on support rods provided at both ends thereof, and is linked to an operating rod opposite to the support rod. , and the lower end of the operating rod is connected to one end of a connecting device of a predetermined length provided along the longitudinal direction of the frame, and the operating body provided in the middle of the frame is connected to the other end of the connecting device. By moving the gripping part of the operating body left and right along the longitudinal direction of the frame, the connecting tool is rotated about the support shaft in the intermediate part, thereby operating one end side of the connecting tool, and at the same time The operating rod is operated in the vertical direction to enable the louver blades to be opened and closed, and furthermore, a drop lock is provided in the middle of the frame adjacent to the operating body or adjacent to the other end of the connector. It is characterized in that the drop lock remains locked when the louver blade is open.

(Example) Fig. 1 shows a partially exploded perspective view of the essential parts of the louver door of the present invention which is used as a rain door. Louver blades 2 are rotatably supported in holes 3 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, the rotation axis, and when the operating rod 5 is pushed downward, the louver blades 2... are all opened and activated. It is formed so that it can all be closed by pushing the rod 5 upward. 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. 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 surrounding side frames, 10 and 11 are left and right vertical frames, 12 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 the operating rod 5 up and down shown in Fig. 1, Fig. 3 is a diagram showing how it is attached to the lower frame, and Fig. 4 is a similar diagram showing the operation. A cutout groove 5b is formed in the L-shaped metal fitting 5a of the rod 5. The connecting tool 8 has a support shaft 8b in the middle portion and engagement 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, 9b 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, which is attached to the lower frame adjacent to the operating body. Lock rod 14a
The vertical movement mechanism has the same structure as a conventionally known mechanism. In other words, FIG. 3 shows a state in which the sliding plate 14b in the lock base (not shown) mounted on the lower frame is moved to the left by operating the handle 14f, and in this case, the engaging protrusion 14c is It moves so as to fit into the recessed part 9d of the operating body 9. Reference numeral 14d indicates a diagonal hole, and the lock rod 14a has an engaging pin 14e that moves vertically along the diagonal hole so that it can 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 14c 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.

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.
