In view of the above-mentioned disadvantages, the object of this invention is to provide a shutter-type storm door that ensures security measures.

[Disclosure of invention]

In order to achieve the above object, the shutter-type storm door according to the present invention is a shutter-type storm door in which a shutter body consisting of a large number of slats is opened and closed along slat guides fixedly installed on both sides of the shutter body. It is equipped with a locking mechanism that locks the movement of the shutter body when an artificial opening operation is applied from the outside to the shutter body. A lock interlocking piece is inserted into the shutter body and is configured to move in the direction of opening the shutter body by the above-mentioned manual opening operation. a locking member supported by a partial slat, the locking member and the lock interlocking piece are engaged through a guide pin and a guide groove, and the movement of the locking interlocking piece in the opening direction The locking member rotates and presses into engagement with the slat guide to stop the movement of the shutter body, and the locking member moves in the opposite direction to the rotation by the lock interlocking piece moving in the opening direction and returning in the opposite direction. It is characterized by the fact that it rotates and separates from the slat guide to release the lock.

This invention will be explained in detail below with reference to the drawings showing the embodiments thereof.

FIG. 1 shows an example of a shutter-type storm door according to this invention, and as shown in FIG. 2, this shutter-type storm door is configured to be attached to a three-sided bay window 1 of a house. This bay window 1 is equipped with four slat guides 2 including those not shown in the figure, a lower frame 3 connecting the lower ends of the slat guides 2, and a roof 5 with an outdoor inspection plate 4. A sliding front window 6 is provided, and fixed side windows 7 are fitted on both sides. As shown in Fig. 1, the slat guide 2 has a U-shaped groove.
A shutter type rain door 8 is incorporated so that it can be moved up and down by these slat guides 2. This shutter 8 is arranged so that the front and both sides can be opened and closed, respectively. As shown in FIG. 2, each shutter 8 has winding cores 9 provided on the front and both sides of the roof 5.
It is becoming more and more involved. This winding onto the winding core 9 may be done electrically or manually. Of course, these types may also be used in combination. The shutter 8 has a large number of slats 10.
The main part is a shutter body with a series of . The slat 10 of the shutter main body is
As shown in Fig. 4, a wing-shaped main body made of aluminum is filled with a soundproofing and heat insulating material 11 made of urethane foam material with high soundproofing and heat insulating effects, and the upper end thereof is The J-shaped connecting protrusion 12 has a connecting recess 13 formed at its lower end. The connecting protrusion 12 is engaged with the connecting recess 13 of the adjacent slat 10, so that the slat 10 is connected to the connecting protrusion 12. The connecting protrusion 12
slits 14 are arranged in the slits 14, and these slits 14 are exposed only when the shutter 8 is pulled and the slats 10 are separated, thereby communicating the indoor side and the outdoor side. It is designed to allow sunlight and ventilation. An end slat 15 is connected to the lower end of the shutter 8. The end slat 15 is formed by a U-shaped frame with a connecting protrusion 12 at the upper end, and a locking slip 16 protrudes from the lower end so as to face each other. A slit-shaped through hole 17 is provided. The end slats 15 are connected by engaging the connecting protrusion 12 at the upper end with the connecting recess 13 of the lowermost slat 10, and are provided so as to be guided by the slat guide 2 and moved up and down. There is. At both horizontal ends of the end slat 15, as shown in FIGS. 1 and 3, there are mounting brackets 1, one on the indoor side and one on the outdoor side.
8 are fixed and these mounting brackets 18
A plate-shaped locking member 20 that rotates around the rotational support shaft 19 is attached. This locking member 20 is located on both end slats 15. The lock member 20 is provided with a guide pin 21 at one end thereof, and the guide pin 21 is slidably fitted into an elongated guide groove 23 provided in the lock interlocking piece 22. Lock interlocking piece 22
is equipped with a rectangular fitting frame portion 24 and an inverted T-shaped push-up receiving portion 25. As shown in FIG. 4, the fitting frame 24 is inserted into the end slat 15 so as to be able to move up and down, and is normally pushed back down by a return spring 26 on its upper side. It's summery. The push-up receiving portion 25 projects downward from the end slat 15 through the through hole 17, and the plate portion at the lower end extends into the slat guide 2, as shown in FIG. This is to prevent the hand from reaching the end slat 15 and pushing it up directly. On the other hand, a spherical lock portion 27 is provided at the other end of the lock member 20, and this lock portion 27 may be fixed in a recess 28 of the lock member 20 or may be rotatable. Furthermore, the lock portion 27 may be formed in a cylindrical (or cylindrical) shape. In the shutter-type shutter of the above configuration, the lock interlocking piece 2
2 is pushed upward against the return spring 26, the guide groove 23 pushes the guide pin 21 upward, as shown in FIG. , rotate in a counterclockwise direction. This results in
The lock portion 27 at the tip is pressed against the bottom wall of the groove of the slat guide 2 so that it does not open at all even if the shutter body of the shutter 8 is lifted up any further. Normally, the lock interlocking piece 22 is pushed back downward as shown in the figure by the return spring 26, and the lock part 27 is rotated clockwise and returned.
is separated from the slat guide 2, so that the shutter body of the shutter 8 can be freely moved up and down.

Because of this structure, even if an intruder attempts to open the shutter body of the shutter 8 by lifting the shutter body of the shutter 8 when the shutter 8 cannot be locked, the locking device is automatically activated and the shutter cannot be opened any further. , crime prevention is ensured. Of course, even when the shutter body of the shutter 8 is in a fully closed state, the locking device is designed to work as long as an artificial opening operation is applied from the outside.

Note that the lower end of the push-up receiving portion 25 and the end slat 15
If there is a small gap between the lower ends of the frame so that a finger cannot fit therein, an intruder will definitely try to lift it up via the push-up receiving part 25. Push-up receiver 25
If a front cover 29 extending to the front wall of the end slat 15 is provided at the outdoor end of the slat 15 as shown in FIG. 4, the same effect can be obtained even without the above-mentioned small gap. In this case, the gap can also be made larger. Said slat 10
is equipped with a slit 14 and is operated to open and close the slit 14, but the slit 10 does not have the slit 14 and is connected so that the slats 10 are always close to each other. This idea can also be applied.

[Effect of idea]

As we have seen above, the shutter-type storm door according to this invention has a structure in which the movement of the shutter body is locked in response to an artificial opening operation applied from the outside to the shutter body, which is made up of a number of slats arranged in series. Since the area is well-established, crime prevention measures will definitely be taken.

In particular, in this invention, the locking mechanism is inserted into the end slat on the open side of the shutter body with a portion protruding outside, and is moved in the direction of opening the shutter body when the manual opening operation is performed. The lock member is supported on an end slat so as to be rotatable in conjunction with the lock interlocking piece only by mechanical means, and the lock member and the lock interlocking piece are connected to each other. are engaged by the guide pin and guide groove,
As the lock interlocking piece moves in the opening direction, the locking member rotates and presses into engagement with the slat guide to stop the movement of the shutter body, and the movement of the locking piece in the opening direction causes the locking member to rotate and press into engagement with the slat guide to stop the movement of the shutter body. Due to the return, the lock member rotates in the opposite direction to the rotation and moves away from the slat guide to release the lock. Therefore, a motor, brake, or other electrical means is required to operate the lock mechanism. Since there is no intervention at all, even if the power supply wiring is cut off or the electrical circuit is manipulated,
There is no need to worry about the lock mechanism being released.

This is because when a thief or the like attempts to break into a residence, it is common for a thief to cut off the power supply wiring in order to disable an alarm device or the like. in this case,
Shutter-type storm doors equipped with conventional electrical locking mechanisms are completely useless and can easily be unlocked and the shutters opened.

However, if the locking mechanism is operated only by mechanical means without using any electrical means, as in this invention, the locking mechanism can be released even if the electrical system, such as the power wiring, is manipulated. It is impossible to do so, and it is extremely effective as a crime prevention measure.
