Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a manually openable shutter.

[0002]

[Prior Art]

 Conventionally, in a general manual opening / closing shutter, a plurality of slats extending in the width direction are connected vertically, and both sides of these slats are guided by a pair of rails so that they can be raised and lowered, and a seat plate is attached to the lower end of the slats. It has a structure that is connected. The seat plate is formed in an inverted T-shape in cross section, contacts the floor surface when fully closed, and hits the ceiling when fully opened to function as a stopper. A case with a built-in winding mechanism is installed at the upper end of the rail, and when fully opened, the slats are wound around the shaft of the winding mechanism to accommodate it. The hoisting mechanism uses the hoisting torque of the hoisting spring to urge the slat to withstand its weight load in order to facilitate the door opening operation.

By the way, when a shutter of this type is closed, the seat plate is located on the ceiling at the fully open position and cannot be closed because it cannot be reached. Therefore, in the past, the shutter was pulled down using a hook bar with a hook-shaped tip to close the door. In other words, insert the end of the hook rod into the hole of the seat plate, lower the seat plate to a height that you can reach, then remove the end of the hook rod from the seat plate and push down the seat plate by hand to complete the door closing work. is doing. Also, when opening the shutter, it is sufficient to lift the seat plate from the floor and push it up all the way until it reaches the ceiling, but it stops at an intermediate position (front of Amai) where the seat plate cannot reach. In this case, the tip of the hook bar is applied to the bottom surface of the seat plate and pushed up to the door open end position (ceiling).

[0004]

[Problems to be solved by the device]

 As described above, the hook rod is indispensable for opening and closing the shutter in the related art, but since the hook rod is a separate part from the shutter, it is easy to lose it, and therefore an appropriate storage place must be secured. Also, the work of inserting the tip of the hook rod into the hole of the seat plate is troublesome, and the position of the hole of the seat plate cannot be determined, especially in the darkness at night, and the insertion work is extremely difficult. Therefore, an object of the present invention is to provide a manually openable shutter that does not require a storage space for hook bars, eliminates the troublesome insertion work at night, and saves the trouble of opening and closing work.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the first invention is to connect a plurality of slats extending in the width direction up and down, guide both side parts of these slats so that they can be moved up and down by a pair of rails, and at the lower end of the slats. In a manually-openable shutter that connects a seat plate, one end of a lifting operation rod is pivotally supported at a side end of the seat plate, and the lifting operation rod is at least in a hanging position perpendicular to the seat plate and the seat plate. It is characterized in that it can be rocked to and from a horizontal position. In the second invention, a plurality of slats extending in the width direction are vertically connected, and both side portions of these slats are vertically guided by a pair of rails, and a seat plate is connected to a lower end portion of the slat. In the opening / closing shutter, a pivot member for pivotally supporting one end of the lifting operation rod is provided on the seat plate so as to be movable horizontally along the seat plate, and the lifting operation rod is at least vertical to the seat plate. It is characterized in that it can swing between a simple hanging position and a horizontal position along the seat plate. In addition, in the present invention, the slat includes a plate member and a pipe member.

[0006]

[Action]

 According to the first invention, when the shutter is opened, the seat plate is pulled up partway and the elevating operation rod is swung to the suspension position. Here, when the lifting operation rod is pushed up, one end of the lifting operation rod and the seat plate are connected, so the seat plate can be pushed up to the fully open position (ceiling). Since the raising / lowering operation rod swings at the side end position of the seat plate, the raising / lowering operation rod is hung and supported by the side end portion of the shutter when the shutter is fully opened, which interferes with the raising / lowering operation rod. Never.

When the raising / lowering operation rod is pivotally supported on the side end portion of the seat plate as in the first invention, the shutter (slat, seat plate) tilts when the raising / lowering operation rod is pushed up or pushed down, so that the lifting / lowering rod is smoothly moved up and down. There are times when you don't. This is particularly noticeable in the case of a shutter having a long width. Therefore, in the second invention, the raising / lowering operation rod is pivotally supported by the pivot member which is movable along the seat plate. With this, the lift operation rod is hung on the side edge of the seat plate so that it does not get in the way when it is fully opened, and when opening and closing, move the lift operation rod to the center of the seat plate and push down or push up the center part of the seat plate. As a result, the shutter can be prevented from tilting and can be smoothly moved up and down.

In the case of the first and second inventions, unless the elevating operation rod is oscillated to a horizontal position along the seat plate, the elevating operation rod always hangs downward due to gravity. However, if the raising / lowering operation rod hangs downward when closing the shutter, there is a problem that the tip of the raising / lowering operation rod collides with the floor surface and a large impact force acts on the shutter. Therefore, it is desirable to provide a holding means for holding the lifting operation rod at the horizontal position with respect to the seat plate. As the holding means, for example, a spring piece can be used. If it is possible to hold the lifting operation rod in the horizontal position in this way, by holding the lifting operation rod on the holding means with the shutter pulled down to the intermediate position, it is possible to prevent the lifting operation rod from colliding with the floor surface. it can.

In the first and second inventions, the lifting operation rod may be attached to the outer surface of the seat plate, but this is an obstacle because the lifting operation rod is exposed to the outside when not in use. Therefore, it is desirable to form a housing portion that is opened downward in the seat plate and that can be stored in a state where the lifting operation rod is swung to the horizontal position. In this case, the elevating operation rod can be housed inside the seat plate, so that the elevating operation rod does not get in the way and the appearance is good.

【Example】

 1 to 6 show a first embodiment of a manually opened / closed shutter according to the present invention, in which a plurality of plate-like slats 1 extending in the width direction are vertically connected, and both side portions of these slats 1 are paired with a pair of rails 2. , 2 to guide the slat 1 so that it can be moved up and down, and a seat plate 3 having substantially the same length as the slat 1 is connected to the lower end of the slat 1. A storage case 4 having a built-in winding mechanism 5 is provided at the upper end of the rail 2, and the winding torque of the winding mechanism 5 causes the slat 1 to be wound up against its weight load to facilitate the door opening operation.

As shown in FIG. 5, the seat plate 3 has a substantially L-shaped cross section, and one end portion of the lifting operation rod 6 is provided on the back surface side of one end portion of the seat plate 3 with the pin 7 and the bracket 8 interposed therebetween. Are pivotally supported. Therefore, the elevating operation rod 6 can be swung between a hanging position vertical to the seat plate 3 and a horizontal position along the seat plate 3. A grip portion 6a is provided at the other end of the lifting operation rod 6. As shown in FIG. 6, a holding piece 9 made of a spring piece is fixed to the back surface of the seat plate 3 corresponding to the vicinity of the grip 6a when the lifting operation rod 6 is swung to a horizontal position. When the raising / lowering operation rod 6 is swung to the horizontal position, the outer peripheral portion thereof elastically engages with the holding piece 9 so that the raising / lowering operation rod 6 can be held in the horizontal position. The holding of the lifting operation rod 6 can be easily released by forcibly pulling down the lifting operation rod 6 against the holding force of the holding piece 9. The length of the lifting operation rod 6 is, of course, shorter than the entire length of the seat plate 3, but when the seat plate 3 is pushed up to the fully open position (ceiling), the lifting operation rod 6 that is in a standing position hangs down. It is necessary to have a length such that the hand can reach the grip portion 6a. It should be noted that it is desirable that the elevating operation rod 6 is formed of a metal pipe in order to secure a bending strength of a certain level or more and to reduce the weight as much as possible.

In order to open the shutter in the fully closed state (see FIG. 1) in the shutter of the above embodiment, the seat plate 3 is lifted to a certain height, the lifting operation rod 6 is detached from the holding piece 9, and shaken downward. Move it to the suspended position. Here, when the elevating operation rod 6 is pushed up, the shutter can be easily opened to the fully open position (see FIG. 3), that is, the position where the seat plate 3 contacts the ceiling. In the fully open position, the lifting operation rod 6 is suspended from the side end of the shutter, so that the lifting operation rod 6 does not become an obstacle. On the other hand, in order to close the shutter in the fully open state, first, the lifting operation rod 6 suspended at the side end is pulled downward, and the seat plate 3 is pulled down to a position where it can be reached. Here, the elevating operation rod 6 is horizontally swung to engage the holding piece 9, and the elevating operation rod 6 is held at a position along the back surface side of the seat plate 3. The seat plate 3 can be lowered to the fully closed position (floor surface) by holding the seat plate 3 and pulling it down further.

7 to 11 show a second embodiment of the manually openable / closeable shutter according to the present invention, and the configurations of the slurry 1, the rail 2 and the case 4 are the same as those of the first embodiment. In this embodiment, the seat plate 10 is formed into a substantially rectangular tube shape in cross section, and a continuous accommodating portion 11 having an open lower portion is formed inside. A pair of rail grooves 12 are formed on the front and rear sides of the housing 11 over the entire length. A pair of rollers 14, 14 are rotatably supported in the rail groove 12, and the rollers 14 are rotatably connected by a U-shaped connecting fitting 15 to form a pivot support member 13. .. One end of an elevating operation rod 16 made of a metal pipe is fixed to the inner surface of the connecting fitting 15 by a knock pin 17, and the elevating operation rod 16 has a roller 14 as a fulcrum and extends downward along the seat plate 10. It is swingably supported with respect to the horizontal position. Particularly, when the raising / lowering operation rod 16 is swung to the horizontal position, the raising / lowering operation rod 16 is completely accommodated in the accommodation portion 11 of the seat plate 10. A grip portion 16a made of a flexible material such as rubber is attached to the other end of the lifting operation rod 16.

A holding piece 18 made of a spring piece having an opening on the lower surface is fixed on the inner surface of the housing portion 11 and at a substantially central position of the seat plate 10. The holding piece 18 is an outer peripheral portion of the lifting operation rod 16. Can be elastically held in a horizontal position. The free end 18a of the holding piece 18 projects downward from the lower surface of the seat plate 10, and when the shutter is fully closed, the free end 18a of the holding piece 18 contacts the floor surface before the seat plate 10. .. Therefore, when the free end 18a hits the floor surface of the seat plate 10, the holding piece 18 is deformed in the opening direction, and the holding of the lifting operation rod 16 is released. In this manner, the holding piece 18 releases the holding of the lifting operation rod 16 in the fully closed state and can swing downward. Therefore, when the shutter is opened, the lifting / lowering operation rod 16 automatically hangs downward, and the problem that the seat plate 10 of the shutter is erroneously pushed up to an unreachable position while holding the lifting / lowering operation rod 16 is eliminated. it can.

Further, a front-back rib 19 projecting downward is formed on the ceiling surface of the housing portion 11 which is separated from the holding piece 18 by a predetermined distance. The ribs 19 prevent the rollers 14 from rolling on the ceiling surface of the accommodating portion 11 when the lifting operation rod 16 is moved to the center position of the seat plate 10 and the seat plate 10 is pushed up. The height of the rib 19 is set to be smaller than the difference between the distance from the ceiling surface of the housing portion 11 to the rail groove 12 and the diameter of the roller 14.

In the shutter of the above embodiment, when the shutter is fully closed (see FIG. 7), the raising / lowering operation rod 16 is swung to the horizontal position and housed in the housing portion 11 of the seat plate 10. As a result, the lifting operation rod 16 is stored inside the seat plate 10 and is not exposed to the outside. Now, when the seat plate 10 is lifted up to a predetermined height to open the shutter, the lifting operation rod 16 is disengaged from the holding piece 18, so the lifting operation rod 16 automatically swings downward and is suspended. And Here, the pivot member 13 is moved toward the central portion of the seat plate 10, and is moved to a position where the elevating operation rod 16 abuts the holding piece 18, that is, the central position of the seat plate 10. When the elevating operation rod 16 is pushed up at this position, the roller 14 hits the ceiling surface of the housing portion 11 and pushes up the central portion of the seat plate 10. Therefore, the force in the tilt direction is not applied to the shutter, and the shutter rises smoothly. At this time, since the rolling of the roller 14 is restricted by the rib 19, the position of the elevating and lowering operation rod 16 is stabilized, and the pushing-up operation becomes easy. When the seat plate 10 reaches the ceiling and reaches the fully open position (see FIG. 8), the lifting operation rod 16 may be moved to the side end portion of the seat plate 10 and suspended at a position where it does not interfere. On the other hand, to close the shutter, the raising / lowering operation rod 16 located at the side end is moved to the center position where it comes into contact with the holding piece 18, and the raising / lowering operation rod 16 is pulled down at this position. Then, the seat plate 10 is pulled down via the roller 14, and the shutter is lowered. Also in this case, since the central portion of the seat plate 10 is pulled down, the force in the tilt direction does not act on the shutter, and the shutter smoothly descends. After lowering the seat plate 10 to a position where it can be reached, the raising / lowering operation rod 16 is moved to the side end side, and the raising / lowering operation rod 16 is further swung horizontally to be locked to the holding piece 18. Then, the seat plate 10 is fully closed by lowering it to a position where it comes into contact with the floor surface.

Although the pivot member 13 is composed of the roller 14 rolling in the rail groove 12 of the seat plate 10 and the connecting member 15 in the above embodiment, the present invention is not limited to this, and the roller 14 may be omitted. It may be slidable along the inner surface of the seat plate 10. In this case, the structure of the seat plate 10 can be downsized.

[0016]

[Effect of the device]

 As is clear from the above description, according to the first invention, one end of the lifting operation rod is pivotally supported on the side end of the seat plate so that it can be lost like a conventional hook rod. There is no need to secure a storage place, and the troublesome work of inserting the tip of the hook rod into the hole of the seat plate can be eliminated. Also, in the fully open position of the shutter, the lifting operation rod is suspended and supported by the side end of the seat plate, and in the fully closed position, the lifting operation rod swings to the horizontal position along the seat plate. Does not get in the way. Further, according to the second invention, since the lifting operation rod is pivotally supported through the pivot member that can move along the seat plate, the side end portion of the seat plate does not interfere with the lifting operation rod when fully opened. It can be hung at the bottom of the seat and the opening / closing rod can be moved to the center of the seat when opening and closing to push down or push up the center of the seat. Therefore, the shutter can be prevented from tilting and can be smoothly moved up and down.
