Description

[Detailed description of the invention] (Field of industrial application) This invention connects adjacent storm shutters by interposing a connecting device, so that all the shutters can be opened and closed in succession by only opening and closing one end of the shutter. This invention relates to an electric automatic storm door device.

(Prior Art) As a conventional electric storm door device, one is known in which a wire rope is wound around the upper left and right ends of a storm door frame, and the wire rope is rotated by a drive motor to automatically open and close the storm door. Since this type of electric storm door device generally folds and opens and closes multiple storm doors, it requires space to fold and open the shutters, so it is difficult to implement this on storm doors installed in ordinary homes. is difficult in practice. It is no exaggeration to say that this, along with the soaring installation costs, is one of the reasons why it is difficult to install electric storm shutters in ordinary households.

(Purpose of the invention) This invention was made in view of the above circumstances.
Unlike the conventional rope-driven electric storm door system, which folds and opens and closes the shutters, it uses a normal shutter storage format in which the shutters are stacked one after another in a door pocket, but it can be automated and can be adjusted as needed. The objective is to propose a shutter device that can be switched between automatic and manual mode with a single touch from inside the room.

(Structure of the invention) In order to achieve the above object, the present invention is an electric rain door device in which the rain door is opened and closed by a rope rotated by a drive motor, in which the first rain door is suspended above the rain door, and the other rain doors are suspended on the lower frame rain door rail. The vehicles are connected to each other so that the vehicle can travel, and switching between automatic and manual mode in the drive motor is performed by a clutch operating lever that projects from the drive motor side toward the indoor side.

(Example) The present invention will be explained below based on the illustrated example.

First, an overview of the implementation of the present invention will be described. In FIGS. 1 to 4, a plurality of shutters 1 and 2 are attached to a shutter frame 31, and in this example, a pulley P1 is attached to the upper end of the shutter frame 31. P2 is disposed, and a rope R is stretched between the pulleys, and the rope is rotated by a drive motor M to open and close the shutters 1 and 2. As for the shutters, the leading shutter 1 is suspended above, and the other shutters 2, 2 run on the lower frame shutter rail 3. In addition, the front and rear ends of the storm door are formed diagonally, and the door pocket 32 where there is no shutter rail is provided.
The first shutter inside can push the other shutters towards the back. The shutters are connected by a connecting tool 4, and one end 41 of the connecting tool
is pivotally attached to one shutter, and the other end 42 is movably attached to another shutter. Furthermore, in the shutters 1 and 2, the first shutter 1 and the other shutters 2,
Rollers 5 and 5 are attached to the vertical shaft 5 on the upper and lower frames of 2, respectively.
The rollers 5 are rotatably mounted on the frame surface 1, and the peripheral surfaces of these rollers 5 are slightly exposed to the outside from the frame surface. In this way, when the rollers 5 are attached to the horizontal stiles of the shutters 1 and 2 so as to be exposed from the side surfaces of the shutters, the frictional resistance against the shutter frame can be reduced and the shutters can be moved easily. In addition, regarding the above-mentioned pulley, as shown in FIG. 5, by providing an auxiliary pulley P3 near the drive-side pulley P1 and winding the rope R multiple times between these pulleys P1 and P3, It is possible to prevent slips between the pulley and the rope. The drive device 8 that rotationally drives the pulley P1 will be described later.

FIG. 6 is an exploded perspective view of the leading shutter 1, and FIG. 7 is an exploded perspective view of the other shutter 2. Both of these shutters 1 and 2 include upper frames 11, 21, lower frames 12, 22, and left and right vertical frames 13. .
It is provided in the notch.

In the leading shutter 1, door wheels 14, 14 for hanging from above
At the same time, a tension adjustment fitting 15 for the rope R is attached to the upper stile 11. As shown in FIG.
While screwing the adjustment bolt 15c to the fixed piece 15b of a, engaging the movable piece 15e to the notch groove 15d of the metal fitting board 15a, and screwing the adjustment bolt to the movable piece 15e in the same manner as the fixed piece, The ends of the rope R are fixed to these pieces 15b and 15e, and the tension of the rope R is adjusted by moving the movable piece 15e by turning the adjusting bolt 15c. Since the end edge of the rope R is fixed by wrapping the upper and lower screws, it is possible to avoid the rope becoming loose as would normally occur with a single screw. Note that the door roller 14 is equipped with a retaining roller 14.
b is attached so that upward movement of the door roller 14 is restricted by the shutter frame 31.

The shutter device of the present invention is further shown in Figures 9 to 1.
As shown in FIG. 4, a connector 4 is interposed between the shutters 1 and 2. That is, one end 41 of the connector is rotatably attached to the adjacent end of the first shutter 1, and in this example, the guide rail 6 is provided laterally on the back surface of the other shutter 2, and the other end 42 of the connector is attached to the guide rail so that it can run. In the embodiment, the connector has both ends 41 and 42 pivotally connected by a connecting rod 43, and although one end 41 is fixed to the shutter 1, the connector itself can freely rotate.
Further, the other end 42 is equipped with trochanters 42a, 42a, and by fitting the trochanters into the guide rail 6, the other end can run on the guide rail without coming off the guide rail. However, connector 4
Of course, it is not limited to the embodiment described above, and the number of installed shutters,
It goes without saying that the location etc. should be selected as appropriate. In normal cases, a pair of connectors 4 are attached to the upper and lower parts of the shutter. An elongated hole 42b is formed in the other end 42 of the connector 4 to provide some play in the pivot between the other end and the connecting rod 43. Therefore, the door pocket storage of the shutter (second
(See Figure 3), the shutters 1 and 2 can be arranged side by side without being diagonal, so that even when using not only two shutters as in the embodiment but a large number of shutters, they can be arranged neatly as shown in the figure. The shutter can be stored inside the door pocket. In the figure,
One end 41 of the connecting tool has its lower part bent to form a mounting piece 41a with the connecting rod 43, and a hanging piece 41b that serves as a stopper when the connecting rod 43 rotates is formed on one side of the mounting piece. are doing. 44 is a back plate.

In FIG. 7, the trochanter 42 of the other end 42 of the connector
When a, 42a is installed in the guide rail 6, it is inserted through the notch of the guide rail, and the cover member 61 is then attached to the notch. In addition,
23a is a cap for the vertical frame. Further, a cleaner 71 is attached to the lower part of the block 7. This cleaner 71 is Finn 71
The center part of a is cut to correspond to the lower frame shutter rail 3.

As shown in FIGS. 15 to 18, in the drive device 8, the driving force from the drive motor M is transmitted to the worm W1 and the worm gear W2 via a reduction gear, and this is provided integrally with the worm gear shaft 82a. It is linked to pulley P1 via a clutch 82. This clutch 82 connects a worm gear shaft 82a with a pulley P1 attached to the lower end of the worm gear W.
2, and the cutout part 8
2c is formed into a clutch shaft core 82b that is retractably inserted into a worm gear shaft 82a, and rollers 82d, 82d are installed at a location of the worm gear shaft 82a corresponding to the worm gear W2 so that they can retract and retract in the radial direction of the shaft. Normally, the clutch shaft 82b is biased to protrude by the spring 82e, and the roller 82d is brought into pressure contact with the worm gear W2, thereby drivingly connecting the worm gear W2 and the worm gear shaft 82a, while the clutch shaft 82b is pushed against the spring 82e. When the roller 82d is buried in the clutch shaft 82b, the roller 82d is loosely fitted into the notch 82c of the clutch shaft 82b, and the pressure contact between the roller 82d and the worm gear W2 is released, and the transmission of the motor driving force is interrupted.

In the present invention having the above-mentioned drive device 8,
As shown in FIGS. 2 and 19, in order to switch the drive motor M between automatic and manual mode, a clutch operating lever 81 is provided protruding from the drive motor side toward the indoor side. In other words, the clutch shaft center 82b is moved in and out using the clutch operating lever 81. In this example, a protrusion 83 is screwed onto the base of the clutch operating lever 81, and a handle is attached to the tip of the clutch operating lever 81. 84, the protruding piece 83 rotates the clutch axis 82b.
When the handle 84 is pressed and the rotation of the handle 84 is stopped, the clutch axis 8 is moved by the spring 82e and the leaf spring 85 that elastically biases the protrusion 83.
2b protrudes to disconnect and disconnect the clutch 82.

In addition, when automatically opening and closing using the rain door device of the present invention, a limit switch 86 provided integrally with the drive device 8 regulates the opening/closing position of the rain door. This limit switch 86 is provided at the bottom of the drive device 8, and has limit pieces 86a and 86b engaged with the wound rope R at two locations on the front and back, and a limit abutment fitting 86c fixed to the rope R when the shutter runs.
When the limit pieces 86a, 86b come into contact with each other, the shutter stops running.

The drive device 8 is screwed onto the shutter frame 31,
As shown in FIG.
The upper frame auxiliary member 31b is screwed onto the web 31a from below, and then the upper frame auxiliary member 31b is screwed on as shown in FIG. With this configuration, the cover 87 can be removed only when the shutters 1 and 2 are opened, which is effective for crime prevention.

Next, the opening/closing operation of the rain shutters will be explained.
First, when opening the shutters 1 and 2 from the closed state shown in FIG. 4, it is sufficient to simply pull the leading shutter 1 toward the door pocket 32. In other words, the shutter 2 is the rail 3
If it is on top, the shutter is regulated by the rail and pushed into the door pocket. If it is pressed again, the restriction will be lifted and the shutter 2 will open as shown in Figure 21.
The leading part is guided by the doorstop block 32a and moves to the back of the door pocket, and the rear end is pressed against the front end surface of the shutter 1, pushing the rear part of the shutter 2 to the back of the door pocket, and further. When the shutter 1 is pushed into the door pocket as shown in FIG. 22, the other end 42 of the connector starts running along the guide rail 6 of the shutter 2, and when the shutter 1 is completely stored in the door pocket, the other end 42
will move to the terminal end of the guide rail 6 (FIG. 23). In this way, just by towing the first shutter 1, the other shutters 2 are also stored in the door pocket.
When pulling out the shutters 1 and 2 from this state, just pull out the shutter 1 in the same way, and the other shutter 2 is pulled out from the door pocket by the connector 4. In addition, although the case where there are two shutters has been explained in the example, even if there are more shutters, by interposing a connecting device in the same way, it is possible to operate only one end of the shutter (storm shutter 1 in this example). All shutters can be opened and closed in succession.

(Effects of the invention) As explained above, the electric storm door device of the invention has the following features:
Since the leading shutter 1 is suspended above and the other shutters 2 run on the lower frame shutter rail 3, the shutters 1 and 2
The opening and closing operation becomes extremely smooth. In other words, when opening and closing the shutters, whether manual or electric,
Since the full load is applied to the leading shutter 1, the shutter may tilt back and forth and come off the wheels.Also, even if it does not come off the wheels, it will remain tilted and run unstable. If it is hung from above, the balance will be maintained by the shutter's own weight, so
The above-mentioned drawbacks are eliminated, and even if the hanging rail extends into the door pocket, it will not interfere with the storage of other shutters.

Moreover, these shutters 1 and 2 are driven by a drive motor M.
The opening/closing operation is performed by a rope R that rotates at the same time, and switching between automatic and manual mode in the drive motor M is performed by a clutch operating lever 81 that projects from the drive motor side toward the indoor side. Therefore, switching between automatic and manual mode can be performed with a single touch from inside the room as needed.

As described above, the present invention simplifies the switching between automatic and manual operation when opening and closing the shutters, and at the same time, since the shutters are linked to each other, the shutters are stable when closed, and are also useful in preventing theft. It has the following effects.
