Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a device for attaching a screen to a head box of a lifting screen.

[Prior Art] In a conventional lifting screen mounting device,
As shown in FIGS. 5 and 6, the upper side of the screen 22 was adhered to the front surface of the head box 2 using pressure tape 31, adhesive material, or the like.

[Problems to be Solved by the Invention] In the case of the above device, when sewing or iron-bonding one side of the pressure tape 31 to the screen, sewing is difficult because the tape stretches. Further, the other side of the tape is adhered to the head box 2 with an adhesive or the like, but this work is also troublesome. Tapes with adhesives are also used to save on-site work, but they have the disadvantage that if the adhesive strength decreases over time, the adhesive parts will separate and the screen will fall.

Furthermore, the screen itself is not only elastic, but also expands and contracts during the sewing process, so the screen can be longer or shorter than the head box. If you glue it to the head box as is, it will look like the one shown in Figure 7. If the screen is too long, the ends will protrude outside the head box, and if the screen is too short, the head box ends 34 will be exposed, making it unsightly. When attempting to align the two ends with each other, there was a drawback that wrinkles 36 were formed in the middle, as shown in FIG. In particular, this defect makes the appearance of the front decoration screen extremely poor.

The purpose of the present invention is to eliminate the disadvantages caused by the use of the pressure tape and adhesive material in the front decoration screen.

[Means for Solving the Problems] In order to achieve the above object, the characteristic means of the device of the present invention is a head box housing the lifting mechanism 1, as shown in the embodiments of FIGS. 1 to 3. 2
A rail groove 3 is provided on the front surface of the rail groove 3, and a number of sliders 4 each having a protrusion side 6 of a snap on the front end thereof are fitted into the rail groove 3. Fasten the tapes 13 attached at regular intervals to the concave side 12 of the snap No.
By engaging the concave and convex portions of the snap,
The screen 21 can be lifted up and suspended from the front of the head box 2 which is common to the screen 11.

[Function] To attach the front decoration screen 21 of the present invention to the head box 2, connect the convex side 6 of the snap of each slider 4 fitted in the rail groove 3 to the snap attached to the screen 21 via the tape 13. It is only necessary to fit the parts into the recessed parts 12 in sequence.

If the screen is wide or large and heavy, fold the screen appropriately and engage the concave side of the snaps attached to the tape 13 in sequence with the convex side 6 of the slider 4 gathered on one side of the head box 2. If the head box is moved and slid in the longitudinal direction of the head box, installation can be made extremely easily.

[Example] The apparatus of the present invention will be specifically described based on an example shown in the drawings.

In the first embodiment shown in FIGS. 1 to 3, the head box 2 is divided into two upper and lower chambers in cross section, the upper chamber is equipped with a bracket fixed to the building (not shown), and the lower chamber is equipped with a bracket that is fixed to the building. A lifting mechanism 1 for raising and lowering the screen 11 is inserted. The lifting string wound around the lifting mechanism passes through a ring on the back side of the lifting screen 11 and is fixed to the lower edge. The hoisting screen opens when the hoisting string is hoisted and closes when it is rewound. A rail groove 3 is provided on the upper front side of the head box 2, and the head 5 of the slider 4 is inserted into the rail groove 3 so as to be freely slidable along the groove 3. A snap convex side 6 with a cutout 7 is formed at the front end of the slider 4, and the convex side fits into a snap concave side 12 attached to a tape 13. The tape 13 is fixed to the upper side of the front decoration screen 21.

As shown in FIGS. 2 and 3, the concave side 12 of the snap attached to the tape 13 has a medium-high hole, into which the convex side 6 of the rod-shaped snap with a concave part of the slider 4 is inserted. insert. The convex side 6 of the snap enters deep beyond the medium-high hole in the concave side 12 of the snap by the cut 7, and the two are joined together. The sprung concave side 12 is sewn to the back side of the tape 13 at regular intervals.

Since the front decoration screen 21 is attached to the head box 2 with snaps, it is easier to attach than adhesive tape and will not deteriorate and come off over time like adhesives do. In addition, even if the screen is large, it can be installed sequentially from the end, and even if the screen is long or short, it can be installed at different positions for good appearance.

A front decoration screen 21 is attached to the slider 4, and a roll-up screen main body 11 is adhered to the lower front of the head box 2 using an adhesive tape 31 in a conventional manner. In this example, the lifting screen main body 11 is attached as before, but since the front decoration screen 21 completely covers the upper part of the main body, there is an inconvenience at the adhesive part of the lifting screen as shown in FIG. However, there is no need to show off your appearance.

As shown in the second embodiment of FIG. 4, upper and lower rail grooves 3, 33 are provided on the front surface of the head box 32, and the lifting screen 11 is suspended by the slider 4 fitted in the lower groove 33. The front decoration screen 21 may be suspended by a long slider 34 fitted in the front panel 3.

[Effects of the invention] As mentioned above, the device of the present invention attaches the front decoration screen or the raised screen to the headbox with a snap, so unlike the conventional device that is attached only with adhesive tape, it does not depend on the size of the screen. Regardless, the installation work is extremely easy, and even if there is a difference between the width of the screen and the width of the headbox, an excellent effect can be obtained in that the screen can always be installed in an attractive manner.
