Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic opening/closing storage device for continuous rain shutters used in buildings such as houses.

[Problems to be solved by the prior art and the invention] In general, in this type of continuous storm door, when adjacent shutters stored in the door pocket in front and back parallel positions are pulled out onto the storm door rail facing left and right, the storm door goes first. Although the following shutters are connected to each other so that they are successively pulled out following the preceding shutters that are pulled out, it is proposed that a drive mechanism for opening and closing the shutters be provided to automatically open and close these consecutive shutters. . By the way, in this case, the shutter needs to be moved in the front-back direction, which is orthogonal to the direction of movement of the shutter rail, so the driving force in the left-right direction from the shutter opening/closing drive mechanism cannot move the shutter smoothly back and forth. There is a problem in that it is impossible to move and it becomes unreasonable.

Conventionally, there has been known a device for actively moving the shutter inside the door pocket in the front-back direction, as shown in, for example, Japanese Utility Model Application No. 56-71880. However, this system is equipped with a conveyor that transports the shutters in the door bag in the front and back direction, and is only capable of automatically transporting them in the front and back direction. In addition to having to drive in the reverse direction, when operating this device in the forward and reverse directions, the relationship with the shutter opening/closing drive mechanism must be taken into account, making the operation cumbersome and complicated. This has become a problem as it has disadvantages such as poor workability.

[Means for solving the problem] The present invention was created in view of the above-mentioned circumstances with the aim of providing an automatic opening/closing storage device for continuous rain shutters that can eliminate these drawbacks. When adjacent shutters stored in a door pocket in a front-back parallel position are pulled out to the shutter rails facing left and right, the shutters are connected so that they follow the shutters that have been pulled out in advance and are pulled out continuously, and In a continuous shutter equipped with a shutter opening/closing drive mechanism for automatically pulling out the shutter to the shutter rail side and storing it in the door pocket side, each of the shutters is provided in the door pocket in the front and back directions substantially orthogonal to the shutter rail. A front-rear moving body that is movable and capable of forward-rearwardly transporting a shutter in a door pocket; a front-rear movement detection mechanism that detects forward-back movement of the shutter; and a left-right movement detection mechanism that detects left-right movement of the shutter. In addition, a drive mechanism for storing the shutter and the drive mechanism for opening and closing the shutter, which are provided for forcibly transporting the front-back transport body in the front-back direction, are connected via a front-back and left-right movement detection mechanism, The structure is characterized in that the shutters are moved back and forth and moved left and right alternately at the same timing.

With this configuration, the present invention is capable of automatically pulling out and storing the storm door in a natural and smooth manner.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a door pocket installed on the side of the opening of a building, and the top plate 1a and the bottom plate 1b of the door pocket 1 have an approximately L-shaped front and rear wall whose middle part is curved in an arc shape. One side of the feed rails 2 and 3 is moved laterally so that the ends of the other side face each other.
That is, as will be described later, it is attached in the front-rear direction that is perpendicular to the left-right direction for opening and closing the shutter D.

Reference numeral 4 denotes an upper transfer body provided so as to be freely movable in the front-rear direction along the upper back-and-forth feed rail 2, and 5 is a lower transfer body provided so as to be freely movable in the back-and-forth direction along the lower back and forth feed rail 3. These transfer bodies 4 and 5 are connected in series by interlocking the transfer slats 4a and 5a, respectively, and have movable bodies 6 and 7 at their inner ends.
are integrally connected.

Reference numeral 8 denotes a drive motor for storing the rain door, which constitutes the drive mechanism for storing the rain door of the present invention.
This storage drive motor 8 is arranged on the indoor inner surface of the door pocket 1, and has a drive shaft 8a extending vertically,
8b is carved with a spiral groove in the opposite direction. The movable bodies 6 and 7 are screwed onto the drive shafts 8a and 8b, respectively, and as will be described later, the movable bodies 6 and 7 are moved in opposite directions by forward and reverse driving of the storage drive motor 8. By moving to
The front and rear transport bodies 4 and 5 are set to be able to move back and forth in the same direction and at the same pitch on the horizontal portions of the feed rails 2 and 3. As shown in FIG. 1, at the position where both the upper and lower transfer bodies 4 and 5 have moved the farthest from the end plate 9, the upper transfer body 4 connects the protrusion 4b provided on the most distal transfer slat 4a with the adjacent upper transfer body. The protrusion 4b of the slat 4a forms a guide groove that substantially coincides with the guide groove of the lintel on the building side (not shown), and in the lower transfer body 5, the protrusion 5b provided on the lower transfer slat 5a on the leading edge side It is set to match the threshold guide 10 on the building side.

On the other hand, reference numeral 11 denotes a drive motor for opening and closing the rain door, which constitutes the drive mechanism for opening and closing the rain door of the present invention. This driven sprocket 13a is arranged on the exit side of the door pocket 1. A receiving roller 15 is provided opposite to the operating roller 13 which is coaxial with the driven sprocket 13a, and the rotation of the operating roller 13 as the shutter opening/closing drive motor 11 is driven in the forward and reverse directions.
As will be described later, the shutter D can be opened and closed by being held between the operating roller 13 and the receiving roller 15 from both sides and forcibly moved in the width direction.

Next, the driving relationship between the storage drive motor 8 and the opening/closing drive motor 11 will be described. 7th, 8th
The figure shows the closed and opened states when there are four shutters, but when closing the shutters,
When you turn on the closing switch (not shown),
As the opening/closing drive motor 11 rotates and the operating roller 13 connected thereto rotates, the shutter D ₁ held between the operating roller 13 and the receiving roller 15 moves left and right in the closing direction. Moving.
When the shutter D ₁ comes out of the door pocket, the closing limit switch pad P ₁ attached to the rear of the shutter D ₁ pushes the shutter limit switch L ₁ to stop the shutter, and the opening/closing drive motor 11 is stopped. After a few seconds according to the timer, the storage drive motor 8 will rotate, both the upper and lower transfer bodies 4 and 5 will move, and the shutter D in the door pocket will move back and forth to the side opposite to the mirror plate 9. At this time, the connecting portions 16 formed on the vertical frames of the shutter D mesh with each other, and the preceding shutter D ₁ and the succeeding shutter D ₂ are connected. When the shutter _D2 reaches a horizontal position where it is exactly in series with the shutter _D1 , the limit switch _L2 for stopping the forward and backward movement of the closing shutter is opened, and the storage drive motor 8 is stopped. After this stop, the opening/closing drive motor 11 resumes rotation, and the shutter _D2 is sent to the closing side. In this way, shutter D
was pulled out of the door pocket and the opening was closed.
When the full-close switch stopper P ₃ attached to the vertical stile of the last shutter D ₄ hits the full-close stop limit switch L ₃ , the full-close circuit is cut off. At this time, as shown in FIG. 7C, a part of the shutter _D4 is
3 and the receiving roller 15, and is fully closed in this state.

On the other hand, when opening the shutter, when the opening switch (not shown) is turned on, the opening/closing drive motor 11 rotates in the opposite direction to that when closing, and the operating roller 13 connected thereto also rotates in the opposite direction. Move shutter _D4 to the door pocket side. Here, each shutter D has a connection part 1
Since they are all connected at 6, at this time all shutters move to the door pocket side. Then, when the shutter D ₄ fits into the door pocket and the shutter D ₃ reaches a state where it is sandwiched between the operating roller 13 and the receiving roller 15, the shutter D ₃
The opening switch stopper P ₄ attached to 3 presses the limit switch L ₄ for stopping the opening shutter feed, and the opening/closing drive motor 11 is stopped. At this time, the connecting part 16 of the vertical stile of the shutter _D4 hits, the limit switch _L5 for starting the forward and backward movement of the shutter for opening closes, and the storage drive motor 8 starts rotating in the opposite direction to that when closing, and moves up and down. The front and rear transport bodies 4 and 5 move back and forth, sending the shutter _D4 toward the mirror plate side. When the shutter is moved back and forth by the estimated thickness of the shutter, that is, one transfer slat 4a, 5a, the limit switch _L6 for stopping the forward and backward movement for opening is closed, and the storage drive motor 8 is closed.
stops. Next, the opening/closing drive motor 11 is rotated several seconds later by the timer, and the succeeding shutter _D3 is sent into the door pocket. In this way, the shutters are stored in the door pocket 1 one after another, but when the shutter D ₁ is sent into the door pocket, the full-open stop limit switch L ₇ is activated.
, the vertical stile of shutter D ₁ hits directly, cutting off all circuits. At this time, as shown in FIG. 8C, a part of the shutter D ₁ remains sandwiched between the operating roller 13 and the receiving roller 15 and is fully opened in this state. The storage drive motor 8 and the opening/closing drive motor 11 are connected via a longitudinal movement detection mechanism and a lateral movement detection mechanism consisting of the above-mentioned limit switches, which respectively detect the longitudinal movement and lateral movement of the shutter D, and the shutter D in the door pocket is It is constructed so that the back and forth movement of D and the left and right movement are performed alternately at the same timing, and can be completely automated.

In the embodiment of the present invention constructed as described above, the opening/closing and storage operations of the storm door D are all performed automatically, but the transport bodies 4 and 5 that move the storm door D back and forth are driven by a drive motor for storage. 8 is provided on the side, and the movable bodies 6 and 7 are moved in the same direction in the horizontal direction by the forward and reverse driving of the motor 8, and the movable bodies 6 and 7 are moved in the same direction. The vertical dimensions are extremely compact, unlike conventional conveyor systems, where there is no need for pulleys and height, and the front and rear feeders 4 and 5 only need to slide in the horizontal direction. It can be made into a vertically fitting size that is substantially the same as a conventional manual type without a forward/backward feeding mechanism.

In the present invention, when the shutter D is opened, closed, and stored, the forward and backward movement and the left and right movement of the rain door D are connected to the storage drive motor 8 and the opening and closing drive motor, which are linked via the movement detection mechanisms in the front and back and left and right directions. 11, it is convenient that the shutter D can be opened, closed and retracted completely automatically.

Furthermore, since the opening/closing movement of the shutters is carried out in a sandwiched manner between the operating roller 13 and the receiving roller 15, the operating roller 13 will idle if an obstacle is encountered, thus ensuring high safety. be. In this case, a load is applied to the opening/closing drive motor 11 as the operating roller 13 idles, but this load is detected and the drive of the motor 11 is stopped, and an alarm such as a buzzer is sounded. This will further improve safety and convenience.

[Operations and Effects] In summary, the present invention is constructed as described above, and includes a drive mechanism for storing the shutters for moving a front-rear moving body capable of transporting the shutters stored in the door pocket in the front-rear direction, and a drive mechanism for moving the shutters from side to side. The shutter opening/closing drive mechanism, which can be moved in the direction and pulled out from the door pocket, is linked via the front/back and left/right movement detection mechanisms of the storm door, and each drive mechanism is controlled by the front/back and left/right movement of the storm door. The drive can be controlled in a correspondingly alternating manner, so that the shutter can be automatically opened, closed, and retracted in a completely automated manner, effortlessly, reliably, and smoothly.
