Description

[Detailed Description of the Invention] The present invention relates to an improvement of a movable louver door, and its purpose is to provide a movable louver door whose louver blades can be opened and closed easily and reliably.

Examples of the present invention will be described below. Fig. 1 shows a perspective view of the main parts of the louver door of the present invention assembled as a storm door, and 1, 1 is a support rod provided at both ends of the louver blade 2, and a pin 4 is inserted into the shaft hole 3 of the support rod. The louver blades 2... are rotatably supported via....... 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 a long hole 6 is formed in the operating rod at a position above the shaft hole 3 to correspond to the shaft hole 3, as shown in the figure. 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... are rotated using the pins 4... as a support shaft, that is, a rotation axis.
If you push the operating rod 5 downward, the louver blade 2...
are formed so that they all open and close when the operating rod 5 is pushed 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, and one end side of the connecting tool is connected to a substantially L-shaped metal fitting 5a attached to the lower end of the operating rod.

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, the connecting tool is moved to the intermediate support shaft 8a.
(The support shaft 8a is rotatably supported by the lower frame.)
As a result, the one end side of the connecting tool operates in the vertical direction, and at the same time, the operating rod also operates in the vertical direction and the louver blade also rotates. 11,10
is a compression spring attached to the upper end of the operating rod 5 and the approximately L-shaped fitting 5a. The spring 11 is compressed between the upper frame 12 and the operating rod 5, and is biased to press the operating rod downward. Further, the spring 10 is compressed between the bottom of the metal fitting 5a and the cover body 13, and is biased so as to press the operating rod downward. In other words, when the operating rod is pushed down via the connector by the rotation of the operating body, spring pressure acts on the spring in a direction that pushes the operating rod downward. With this configuration, when the operating rod is pressed downward, the spring pressure is directed downward, so that the operating rod does not rise by itself.

In particular, when the louver blades are open, it is natural that external forces such as the weight of the louver blades and wind pressure applied to the blades act on the operating rod via the engagement protrusion.
Needless to say, the acting force is in the direction of pushing up the operating rod. When the operating rod is pushed down, the louver blades remain open because the spring pressure is acting downward as described above. In addition, pushing down the operating rod, that is, opening the louver blades, is done by rotating the operating body, but the force to push down the operating rod is assisted by the spring pressure, so the rotating operation of the operating body is easy. It can be done smoothly. 14,15
16 is the left and right vertical frames, 16 is the lower frame, and 13a is a notch hole in the cover body. 17 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 substantially L-shaped fitting 5a of the operating rod 5 has a cutout groove 5b formed therein. A spring 10 is attached to the bottom portion 5c. The connector 8 has a support shaft 8a in the middle and engagement pins 8 on both ends.
b, 8c, and the support shaft 8a is inserted into the shaft hole 16 of the lower frame 16.
A connecting tool 8 is rotatably supported on the shaft. The engagement pin 8b engages with the notch groove 5b, and the engagement pin 8c engages with the arc-shaped engagement hole 9a of the rotating operating body 9. Engagement hole 9
A 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 16b of the lower frame. 9c is a grip portion exposed from the notch hole 13a of the cover body 13, 9d is a recessed portion, and 9e is a convex portion.

FIG. 3 shows the position where the operating rod is moving upward, that is, the louver blade is closed. FIG. 4 shows a state in which the operating rod is moving downward, that is, a state in which the louver blades are open, and in this state, the spring 10 is compressed between the bottom portion 5c and the cover body 13,
A biasing force is applied to the bottom portion 5c. 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. Reference numeral 17 indicates a drop lock, and the vertical movable groove of the lock rod 17a has the same structure as a conventionally known one. In other words, FIG. 3 shows a state in which the sliding plate 17b in the lock base (not shown) mounted on the lower frame has been moved to the left; It has been moved so that it fits in 9d. Reference numeral 17d indicates a needle hole, and the lock rod 17a has an engaging pin 17e that moves vertically along the diagonal hole so that it can protrude and retract from the lower end of the lower frame 16.

Figure 4 shows the sliding plate 17b moved to the right and the lock lever 1
7a is shown dropped below the lower frame of the shutter, that is, inserted into the lock hole of the lower rail (shown below) and locked. Thus, the engagement protrusion 17c 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. 17f is a handle. Reference numeral 18 denotes a stopper base body having an uneven shape attached to the side of the lower frame, and 19 denotes a stopper pin that engages at a suitable position in a recessed portion of the base body, 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 20, an operating body 2
1. The shape of the sliding plate 22b of the lock 22 and the operating structure thereof are different from those of the previous embodiment.
One end 20d of the connecting tool 20 is bent into a dogleg shape, and the bent portion is formed so as to protrude more toward the lock than the operating body 21. 20a is the support shaft,
20b, 20c are engagement pins, 21a is an engagement hole, 2
1b is a support shaft, and 21c 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 22c fits into the end 20d (as shown in Figure 5). 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 20d of the connector and cannot be moved to the left. Therefore, the lock rod 22a does not move upward and remains locked. 22d is a diagonal hole,
22e is an engagement pin, and 22f is a handle.

FIG. 7 shows another embodiment in which a connecting tool 20, a rotating operating body 21, and a lock 22 are attached to a U-shaped mounting frame 2.
I attached it to 3 and made it into a unit. 23a,2
3b is a fixing hole for inserting the unit into the lower frame of the shutter.

FIG. 8 shows still another embodiment, the feature of which is that the operating body 24 has a diagonal hole 24a, and the engaging pin 20c of the connector is engaged with the diagonal hole, so that the operating body 24 can be moved left and right (in the direction of the arrow). ) to rotate the connecting tool. Further, the operating rod 5 has an engaging pin 20b engaged with a long hole 5b provided at the bottom of the operating rod 5 without using an L-shaped metal fitting. 25 is a spring;
It is installed between the lower end of the operating rod and the bottom frame, and when the louver blade is open, that is, when the operating rod is moving downward, the spring is biased in the direction of pulling the operating rod downward. There is. Others are the same as above.

As mentioned above, in the movable louver door of the present invention, one end of the connecting tool for moving the operating rod 5 up and down is connected to the operating rod 5, and the other end is connected to the operating body so that the door can be operated by the operating body. Because of this structure, the connecting tool can be provided long to the desired length, and the operating body can be operated from the center of the shutter, for example, to easily and reliably move the operating rod up and down, and by extension, to control the louver blades. Can be opened and closed. Furthermore, when the operating rod is pushed downward, the spring pressure is acting downward, so the operating rod does not rise by itself. In particular, when the louver blades are open, it is natural that external forces such as the weight of the louver blades and wind pressure applied to the blades act on the operating rod via the engagement protrusion, and the acting force is in the direction of pushing up the operating rod. Needless to say, there is.
When the operating rod is pushed down, the louver blades remain open because the spring pressure is acting downward as described above. In addition, pushing down the operating rod, that is, opening the louver blades, is done by rotating the operating body, but the force to push down the operating rod is assisted by the spring pressure, so the rotating operation of the operating body is easy. It can be done smoothly.

Furthermore, if a drop lock is provided as in the embodiment, the locked state will be maintained when the louver blades are open, so there is no fear that the storm door will be stored in the door pocket with the louver blades open, which will lead to damage to the louver blades. There is no.

Although the above embodiment has a configuration in which the louver blade opens when the operating rod is moved downward, it is also possible to adopt a configuration in which the louver blade opens when the operating rod is moved upward. The mounting position of the spring is also not limited to the drawings of the embodiment. In short, the spring may be biased so that when the operating rod is pushed to hold the louver blades in the open state, the spring pressure acts in the direction of pushing the operating rod.

As explained above, the louver door of the present invention is highly practical.
