Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a retractable curtain storage device mainly used as a partition in a factory, an office, a conference room, or a garage.

[Conventional technology and its problems]

Generally, a wind-up curtain of this type has a structure in which a winding drum is rotatably suspended and supported by a base metal member fixed to a required structure, and the curtain body is wound around the winding drum. . Further, in such a winding curtain, the winding drum is rotated in the forward and reverse directions to appropriately partition the space in the required structure.

By the way, while such a conventional wind-up type curtain can easily partition a required space, in particular, when not in use, the curtain body is in a so-called exposed state in which the curtain body is simply wound around the winding drum. The stains on the body itself were conspicuous and very unsightly, and moreover, dust and dust adhered to the stains, making them easily damaged.

In order to solve the problem of the conventional product, a cover body having a U-shaped cross-section with a required length is attached to the base metal, and a winding drum around which a curtain body is wound is rotatably suspended in the cover body. Although it is proposed that the cover is installed and supported, it is not always satisfactory in terms of appearance and stain because the lower surface of the cover body is always open.

The present invention solves all the conventional problems at once, and allows the roll-up curtain to be securely stored and held in the cover body in a concealed state, and the convenient storage that allows the curtain body to be smoothly rolled up and unwound as necessary. It is intended to provide a device.

[Means for solving problems]

That is, according to this invention, a pair of cover members 6 having a required width and length are pivotally mounted on both sides of the support 1 for suspending and supporting the curtain winding drum 2 along the longitudinal direction thereof so as to be swingable. The lower portion of each cover member 6 is bent inward so that the lower end edge 7 of the cover member 6 abuts and closes, and each lower end edge 7 is provided with a guide piece 9 that expands outward. It consists of different configurations.

[Action]

At the time of use, the winding drum 2 is normally rotated to rewind the curtain body 4, and the weight of the weight material 5 attached to the free end of the curtain body 4 causes the cover member 6 to be pushed down and lowered. Further, when storing, the winding drum 2 is reversely operated to wind up the curtain body 4, and the weight member 5 is guided and raised by the guide piece 9 to push up the cover member 6. And the curtain body 4
After being wound up on the winding drum 2, the lower ends of the pair of cover members 6 on both sides are automatically closed to be stored and held in a concealed state.

〔Example〕

An embodiment of the present invention shown in the drawings will be described below.

Reference numeral 1 is a support made of a rectangular pipe that can be attached to a required structure, and 2 is a winding drum of a required length that is suspended from the support 1 via a suspension member 3. Can be rotated forward and backward by a required motor (not shown).
4 is a curtain body which is wound around the winding drum 2 so as to be able to be wound and unwound freely, and 5 is a weight member made of a metal bar attached to a free end portion of the curtain body 4. 6 is the support 1
Is a pair of cover members pivotally attached to both sides of the take-up drum 2 along its longitudinal direction, the cover member 6 having a width and a length for covering the winding drum 2, and a lower portion thereof having a lower end edge 7 Are bent inwardly in a curved shape so as to abut and close each other. Reference numeral 8 is a mounting member for the cover member 6, 9 is a guide piece formed by bending the lower end portion of each mounting member 8 outward along the lower edge 7 of the cover member 6, and 10 is the cover member 6 2 is a cap on which the support 1 is suspended so as to close both ends of the support.

Next, the operation of the storage device configured as described above will be described.

First, at the time of use, the winding drum 2 is normally rotated to rewind the curtain body 4. Then, the weight material 5 of the curtain body 4 gradually descends, contacts the inner surface of the lower end of the cover member 6, and pushes open the lower end edge 7 of the cover member 6 by its own weight,
It escapes from the cover member 6 and descends further. When the weight member 5 escapes, the cover member 6 automatically closes due to its own weight. Then, when the weight member 5 is lowered to a predetermined position, the operation of the winding drum 2 is stopped, and the curtain body 4 is stopped.
To partition the required space.

On the contrary, when the curtain body 4 is to be stored, the winding drum 2 is reversely operated to wind up the curtain body 4. Then, the way material 5 also rises in conjunction with the curtain body 4, and while being guided by the guide piece 9, the lower end edge 7 of the cover member 6 is pushed open by the winding force of the winding drum 2 and stored in the cover member 6. To be done. When the weight member 5 is completely stored in the cover member 6, the lower end edges 7 of the cover member 6 are automatically brought into contact with each other and completely closed (see FIG. 1).

In the above embodiment, the cover members 6 on both sides are pivotally attached to the support body 1, but the present invention is not limited to this, and at least only one of them is pivotally attached. May be. Further, although the guide piece 9 is formed by bending the lower portion of the mounting member 8, it goes without saying that it may be directly provided on the cover members 6 on both sides.

[Effect of device]

According to the present invention, the pair of cover members 6 having the required width and length are oscillated on both sides of the support 1 for suspending and supporting the curtain winding drum 2 along the longitudinal direction. The lower end of each cover member 6 is freely pivoted, is bent inward to close the lower end edge 7 of the cover member 6, and the lower end edge 7 of each cover member 6 is expanded outwardly. Since the curtain bodies 4 are wound around the winding drum 2, the curtain bodies 4 are housed in the pair of cover members 6 on both sides, and the lower end edges 7 of the cover members 6 are brought into contact with each other to automatically It can be closed and kept in a concealed state, has a very good appearance, and is capable of effectively preventing contamination with almost no intrusion of dust or dust. Further, when the curtain body 4 is unwound, the cover member 6 is pushed open by the weight of the weight member 5 itself, and when the curtain member 4 is wound, the weight member 5 is pushed open by the hoisting force while being guided by the guide piece 9. Therefore, the rewinding / winding operation of the curtain body 4 can be performed extremely smoothly.
