Description

[Detailed description of the invention] <Industrial application field> The present invention is a horizontally pulling shutter door equipped with a suspension wheel for hanging from a rail and a guide wheel that rotates along the guide. This invention relates to a winding shaft device for a horizontally pulling shutter door, which is electrically operated to quickly and smoothly store shutter doors in a shutter storage section arranged in a spiral shape.

<Prior Art> Conventionally, the accommodating portion of the horizontal shutter door used in the past has generally been a type in which the horizontal shutter door installed at the front of the building is guided to the side of the building and left as is.

In this case, the horizontal shutter door was manually or electrically driven, suspended from a rail, and guided to the side of the building, changing direction 90 degrees along the way.

In this type of model, in order to prevent the side-pull shutter door from swinging, a guide wheel is attached above the slats of the side-pull shutter door, and the guide wheel runs within the lower guide that faces the upper rail. , ensuring stable running.

In general, shutters with mutually connected slats have low manufacturing precision, so for example, if the width of the slats is 6 cm and 30 of these are installed in a row to manufacture a shutter door with a width of 180 cm, The directional wobble was usually quite large. In the case of both horizontal and vertical shutter doors, this rattling becomes a hindrance when opening, closing, or locking the shutter, so the applicant created the slats shown in Figures 4 and 5 by drawing out aluminum. Manufactured.

FIGS. 4 and 5 show the case where this slat is applied to a horizontally pulling shutter door.

To explain the outline of the structure according to the drawing, 1 is a slat with a substantially rectangular cross section formed by drawing aluminum, and a protrusion 2 for connecting the slat 1 is provided on the right side of the figure, and a protrusion 2 is provided on the left side of the figure. A recess 3 is provided in which the protrusion 2 of the adjacent slat 1 to be connected is fitted. The protrusion 2 and the recess 3 are provided over the entire length of the slat 1 in the longitudinal direction. (See Figure 5) Reference numeral 4 denotes a suspension wheel that rotates parallel to the longitudinal surface of the slat 1 (vertical direction of the horizontal shutter door), and is rotatably supported by the slat 1.
In the figure, the slat 1 is placed on a rail R installed above the horizontal shutter door, and the slat 1 is suspended from the rail R.

Reference numeral 5 denotes a guide wheel that rotates in a direction perpendicular to the longitudinal surface of the slat 1, and is rotatably supported below the slat 1, and is installed below the side-pull shutter door in Fig. 5. Groove-shaped guide G
The lower end of the slat 1 suspended from the rail R by the suspension wheel 4 is guided.

If the rail R and the guide G are maintained in parallel and in an appropriate positional relationship with each other, the slat 1 is suspended by the suspension wheel 4, the lower end is guided by the guide wheel 5, and the slat 1 can freely move on the rail R. I can do it.

The horizontally drawn shutter doors formed in this manner have extremely less rattling between the slats 1, compared to conventional shutter doors, even when they are installed in series. Therefore, it can be easily operated electrically, and the direction of the side-pull shutter door can be changed within a small radius.

As a result, the spiral-shaped guide and the corresponding rail R (not shown), as shown in FIG. 6, have made it possible to roll the horizontal shutter door into a small-diameter shutter accommodating portion. in this case,
The horizontally pulling shutter door is electrically pulled out from or stored in the shutter accommodating portion.

When such a spiral guide G is used, the diameter of the spiral necessary to accommodate a horizontally drawn shutter door with a total length of 3600 cm is 50 cm or less.

When a horizontally pulling shutter door is driven electrically, a rack is attached to the top of each slat of the shutter door, and a pinion that meshes with these racks is driven by an electric motor to open and close the horizontally pulling shutter door.

In such a type, the electric motor is generally buried at an appropriate location along the line of movement of the horizontal shutter door.

<Problems to be solved by the invention> When a horizontal sliding shutter door is operated electrically and is housed in or pulled out from a housing section in which a rail R and a guide G are installed in a spiral shape, the electric motor is operated as described above. The electric motor is buried at an appropriate location along the movement line of the horizontal shutter door, but this location is generally in the ceiling along the roof of the building, and therefore the installation work of the electric motor requires a great deal of time and expense. There were many examples.

The present invention was devised to solve the problem of installing the drive motor for the horizontally pulling shutter door, and the spiral rail R and guide G prevent the horizontally pulling shutter door from being rolled up. This was devised in consideration of the fact that the more it is rolled up, the smaller the diameter of the roll becomes.

<Means for solving the problem> In the case of a type in which the horizontal shutter door is guided by the rail R and guide G arranged in a spiral shape inside the shutter housing, the winding shaft is installed approximately at the center of the shutter housing. Then, by placing the winding shaft under the influence of an electric motor, the winding shaft is driven, thereby making it possible to easily handle the operation of the horizontal shutter door in a smaller volume.

In this case, the winding shaft itself does not need to wind the horizontal shutter door, and the continuous arm connected to the slat 1 at the end of the horizontal shutter door is connected to the winding shaft through a plurality of connecting plates. The winding shaft is driven by an electric motor to operate the horizontal shutter door.
A hinge is interposed between the continuous arm and each connecting plate, and when the horizontal pulling shutter door is extended and retracted, the winding diameter of the horizontal pulling shutter door that moves along the spiral rail R and guide G is adjusted. It is designed to respond to change.

The plurality of connection plates are mutually hinged with hinges, and the driving force of the electric motor is appropriately transmitted to the side-pull shutter door by pins and links protruding at necessary locations.

<Function> According to the present invention, the operation of storing the horizontally pulling shutter door in a spiral shape is easily and quickly performed by the action of the electric motor.

<Example> (Figures 1 to 3) Embodiments of the present invention will be described according to the drawings.

In Fig. 1, reference numeral 10 denotes a rotatable winding shaft, which is installed vertically at approximately the center of the plane of the spiral-shaped guide G shown in Fig. 6, and one end of which is attached to the shutter housing part at its upper end. A fixed electric motor 11 is attached,
A suitable bearing 12 is installed at the lower end.

Reference numeral 13 denotes a protrusion protruding from the winding shaft 10, and a first connecting plate 15 is hinged to the tip of the protrusion via a first hinge 14. A second connecting plate 17 is hinged to the other end of the first connecting plate 15 via a second hinge 16 .

A connecting arm 19 is hinged to the other end of the second connecting plate 17 via a third hinge 18, and a connecting arm 19 is hinged to the other end of the connecting arm 19 via a connecting hinge 20 (see FIGS. 2 and 3). A slat 1 at the innermost end of the horizontally pulling shutter door is successively provided.

Code 21 appearing in Figures 2 and 3
and 22 indicate a guide roller pivotally connected to the downwardly extending connecting arm 19.

Reference numeral 23 in FIG. 1 is a shaft pin protruding from the first connection plate 15, by which the link 24 is pivotally supported.

Reference numeral 25 denotes a pressing pin protruding from the second connecting arm 17, which is inserted into the elongated hole 26 bored in the link 24.
has fallen into.

FIGS. 2 and 3 are conceptual diagrams of a state in which the horizontally pulling shutter door is completely pulled out from the shutter accommodating portion and a state in which it is completely retracted.

When retracting, the electric motor 11 is driven to rotate the winding shaft 10 in a counterclockwise direction as indicated by arrow A in FIG. In this case, the elongated hole 2 of the link 24
6 is the second hinge 1 interposed between the first connecting plate 15 and the second connecting plate 17 in order to pull the pressing pin 25 of the second connecting plate 17 recessed therein as shown by arrow B.
6 points outward from the spiral of guide G and arrow C
Move like this. By this movement, the blocking at the time of initial movement of each connection plate is easily released.

When the winding shaft 10 is continuously rotated by the electric motor 11, each slat 1 of the horizontal shutter door is sequentially drawn into the shutter accommodating portion along the spiral winding of the guide G, and finally, as shown in FIG. reach the state.

Although FIG. 3 shows the state in which the retraction is completed, the connecting arm 19, the second connecting plate 17, and the first connecting plate 15 are bent at the third hinge 18, second hinge 16, and first hinge 14, It is accommodated in a space even smaller than the minimum winding diameter of the horizontal shutter door. (See the chain line circle in Figure 3.) To feed the horizontal shutter door from the state shown in Figure 3, drive the electric motor 11 and rotate the winding shaft 10 clockwise in the direction of arrow D in Figure 3. .

As a result, the elongated hole 26 of the link 24 supported by the shaft pin 23 protruding from the first connecting plate 15 presses the pressing pin 25 protruding from the second connecting plate 17 as shown by arrow E. , since the second connecting arm 17 is pushed out as indicated by the arrow F in the figure, the blocking at the time of initial movement is easily canceled as in the case described above.

If this link 24 is not attached,
The rotation of the winding shaft 10 in the direction of arrow D is caused by the rotation of the first hinge 14 interposed between the protruding piece 13 and the first connecting plate 15.
This appears as a movement in the direction of arrow H in the figure, so that each connecting plate and the connected arm cannot properly send out the horizontally pulling shutter door.

<Effects of the invention> According to the invention, all necessary equipment can be installed in a small volume at the center of the shutter accommodating part, and even though the structure has multiple connection plates, it is easy to Blocking was reliably removed.
This has the effect of making it possible to obtain a winding device with stable operation.
