Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a roll screen device. More specifically, the present invention provides an automatic wind-up type roll screen device that utilizes the elastic force of a torsion coil spring, which covers the opening of a window frame without any gaps, effectively shielding, soundproofing, and insect-proofing. The present invention relates to a roll screen device capable of smoothly performing drawer extension and winding and storing of a screen member without rattling.

(Prior art) Conventionally, various screen members such as curtains, blinds, lightweight shutters, and projection screens have been manufactured by utilizing the elastic force of a torsion coil spring built into a winding roll, applying and accumulating the elastic force, and then releasing and restoring the elastic force. An automatic winding type roll screen device is known that pulls out a roll from a winding roll, and then winds up and stores the screen.

In this conventional roll screen device, one end of a torsion coil spring is fixed inside a take-up roll to which a screen member is attached, and the other end is connected to a rotating cylinder that rotates together with the take-up roll. When the screen member is pulled out and stretched, elastic force is accumulated in this torsion coil spring, and by releasing this elastic force, the screen member is wound onto a take-up roll. Further, the winding roll can be stopped at an appropriate position.

The pulling out and extension of the screen member, the winding up and storage, and the stopping at an appropriate position are realized by a clutch mechanism provided in the roll screen device.

Further, roll screen devices using various winding mechanisms in which various modifications have been made to such mechanisms are also known.

However, in conventional roll screen devices, a gap exists between the window frame opening and the screen member, and due to the existence of this gap, the shielding effect, soundproofing, and insectproofing effects of the roll screen device are incomplete. Moreover, there is also a problem in that the screen member tends to wobble when the screen member is pulled out, extended and rolled up and stored.

In order to solve this problem, the inventors of the present invention arranged guide members on both side edges of the screen member,
A roll screen device with a guide has also been proposed in which the guide members are slidably fitted into the guide grooves of the guide groove members provided on both sides of the screen member. For example, a fastener analog is used as the guide member.

(Problems to be Solved by the Invention) However, the reality is that even with the guided roll screen devices that have been proposed so far, there remain problems that need to be solved.

That is, when the guide member is installed, the flexibility of the screen member's side edges is lost, which not only makes it difficult to pull out the screen member and roll it up and store it smoothly, but also causes the screen member's side edges to expand when it is rolled up and stored. Inevitable. For this reason, there was a drawback that the size and shape of the device could not be shared with a roll screen device that does not have a guide.

The present invention was made in view of the above circumstances, and it eliminates the drawbacks of the conventional guide-equipped roll screen device, makes it possible to smoothly pull out and extend the screen member, and also makes it possible to smoothly pull out and extend the screen member. The object is to provide an improved roll screen device that can be manufactured easily.

(Means for Solving the Problems) The present invention solves the above problems by fixing one end portion inside a take-up roll to which a screen member is attached, and rotating the other end together with the take-up roll. A torsion coil spring connected to a rotating tube is provided, and when the screen member is pulled out and stretched, an elastic force is accumulated in this torsion coil spring, and this is released to wind and store the screen member on a take-up roll. This type of roll screen device consists of a pair of guide groove members with guide grooves facing each other on both sides of the screen member, and bead connectors arranged on both side edges of the screen member, and the bead connectors are connected to the guide grooves. A roll screen device is provided which is slidably fitted into a guide groove of a member.

(Function) In the roll screen device of the present invention, the bead connectors disposed on both side edges of the screen member are slid into the opposing guide grooves provided in the pair of guide groove members on both sides of the screen member. By freely fitting the screen member, the operations of pulling out and expanding the screen member and winding it up can be performed extremely smoothly.

(Example) Next, an example will be shown along with the drawings, and the roll screen device of the present invention will be explained in more detail.

As shown in FIG. 1, the roll screen device of the present invention utilizes the elastic force of a torsion coil spring built into the take-up roll (1) to apply and accumulate and release and restore various types of screens. The member (2) is pulled out and rolled up and stored.

A screen member (2) is attached to this winding roll (1), and bead connected bodies (3) are arranged on both side edges of this screen member (2). Furthermore, a pair of guide groove members (4) with opposing guide grooves are provided on both sides of the screen member (2). The bead connectors (3) provided on both side edges of the screen member (2) are
The guide groove member (4) is slidably fitted into the guide groove portion of the guide groove member (4).

Screen members (2) are installed at both ends of the take-up roll (1).
A recess (5) is also provided for winding up the bead linkage (3). As the screen member (2), a screen member made of any material such as cloth, vinyl sheet, wire mesh, etc. can be used. Also, take-up roll (1)
An appropriate winding mechanism can also be adopted for operating the winding mechanism.

As shown in FIG. 2, the beads (6) of the bead connector (3) attached to both side edges of the screen member (2) are
A packing (8) provided in the guide groove (7) prevents it from coming out of the guide groove (7).

Structure of bead linkage (3) and screen member (2)
There are no particular restrictions on attachment to both side edges. As the bead connection body (3), for example, beads (6) made of metal, ceramics, or resin and having a diameter of about 2 to 3 mm can be connected by a filament.

Since the sliding movement of the bead connector (3) is performed by spherical bodies called beads (6), the sliding contact with the packing (8) is smooth, and the screen member (2) can be pulled out and rolled up very smoothly. Enables storage operations. Its sliding is much smoother than with conventional fastener analogs.

The bead linkage (3) and the screen member (2), for example, as illustrated in FIG.
9), and can be sewn between the beads (6) on both side edges of the screen member (2) with threads (IO), or the sewn parts can be further fixed and attached with adhesive. . In addition, as illustrated in FIG. 4, the weft thread (1
1), the filamentous body (9) may be woven into the screen member (2), or as shown in FIG. It may be welded and integrally formed.

By adjusting the combination of beads (6) and filament (9), the spacing of beads (6) and attachment to screen member (2) can be adjusted as appropriate.

Of course, the invention is not limited to the above examples. Various embodiments are possible in detail.

(Effects of the Invention) As explained in detail above, the present invention provides a roll screen device with a guide that allows for extremely smooth sliding of the screen member by connecting beads and improves the operability of the drawer extension and winding storage. be done. Covers the window frame opening without any gaps, ensuring shielding, soundproofing, and insect proofing.
