Description

[Detailed Description of the Invention] Technical Field This invention relates to a pleated screen that is attached to the inside of a window to adjust the lighting in a room.

BACKGROUND OF THE INVENTION Since ancient times, shoji screens have been used in Japanese houses as partitions to separate the outside world from the inside, or as partitions between rooms.

This shoji screen, made of translucent Japanese paper, blocks direct sunlight to an appropriate degree, counteracting the harmful effects of sunlight while still maintaining a visually appealing appearance.

In other words, it blocks direct light, but transmits and diffuses about half of that light, and serves as a lighting source for the room.

The light diffused by the shoji illuminates the entire room softly, improving the uniformity of illumination on each side of the room and improving the distribution of illumination compared to cases where only transparent windows such as glass windows are used.

Therefore, it corrects the tendency of glass windows, where the window side is extremely bright and the back of the room is extremely dark, creating a strong contrast. Indoor rugs that block infrared rays, ultraviolet rays, and heat rays contained in
It also has the effect of preventing fading and discoloration of walls, furniture, etc.

In addition, at night, white shoji screens reflect lighting, increasing lighting efficiency and creating a brighter field of view, thereby improving the quality of the lighting environment.

However, although shoji has many advantages as mentioned above, it is difficult to replace the shoji, there are problems with durability due to the use of washi paper, and the pattern of the middle crosspiece is Japanese-style, so it is not suitable for modern Western-style shoji. Its use in residential construction has become rare, and its use was inevitably limited in Western-style rooms that do not have thresholds or lintels.

PurposeThe purpose of this invention is to take advantage of the above-mentioned characteristics of shoji while improving its shortcomings, so that it can be widely used for indoor and outdoor shielding, lighting, partitioning, etc., regardless of whether it is Western or Japanese rooms, and the screen can be easily replaced. It is to provide a pleated screen.

EXAMPLE Below, an example embodying this invention will be explained with reference to the drawings. 1 is a screen formed by pasting two sheets of special synthetic Japanese paper with a synthetic resin adhesive, and the screen is fixed horizontally. It is formed in a zigzag shape with folds 1a provided at intervals, and three rows of through holes 1b are provided in a straight line in the vertical direction in the middle of each fold 1a.

2 has a length corresponding to the width of the screen 1 and is made of synthetic resin and has a lid-shaped cross-section, serving as an upper and lower inner frame as a clamping member; 3 is also made of synthetic resin and corresponds to the width of the screen 1; It is a presser frame as a clamping member formed in the shape of a long flat plate, and on both sides of its inner surface, clamping protrusions 3a are provided which protrude obliquely toward Naoko and have circular tips. ing.

Due to the elasticity of the inner frame 2 and presser frame 3, the clamping protrusion 3a is attached to the clamping portion 2 inside the end of the lid-shaped cross section of the inner frame 2.
a, and as shown in FIG. 2, both upper and lower ends of the screen 1 are sandwiched and supported between the clamping portion 2a and the clamping protrusion 3a.

Reference numeral 4 denotes an outer frame made of resin or aluminum and having a U-shaped cross section, and protrusions of unequal length formed on both edges of the U-shaped cross section to face each other. Article 4
a, 4b are provided, and the inner frame 2 and presser frame 3 are supported by the protrusions 4a, 4b.

As shown in FIGS. 3 and 4, the assembly method is as shown in FIG. It is inserted diagonally into the outer frame 4 from the strip 4a side and fitted so as to be locked to the short protrusion 4b.

Reference numeral 5.6 denotes a main mounting bracket and an auxiliary bracket that can clamp and support the upper outer frame 4 by attaching seven bolts to their base ends, and a rectangular bent portion at the center of the main mounting bracket 5. A support bracket 9 is screwed onto the tip of a bolt 8 extending upward from 5a, and can be hung from a curtain rail 10, as shown in FIG.

Reference numeral 11 denotes three operating strings inserted through the through holes 1b of the screen 1, one end of which is removably attached to the presser frame 3 below the screen 1 with a hook 11a, and the other end of the operating string 11. is the presser frame 3 above the screen 1.
It passes through the inner frame 2 and the presser frame 3, and then passes through the stopper 12 described below.
It has reached this point.

Reference numeral 12 denotes a stopper that is fitted and fixed to the inner frame 2 above the screen 1 and the side edge of the presser frame 3, and inside thereof is a roller 13 rotatably supported by the stopper case 12a and the same stopper case 12a. A gear 14 that can move up and down along a step-like stepped portion 12b formed on the inner surface is provided,
An operating string 11 is inserted between the roller 13 and the gear 14, and is turned from a horizontal direction to a vertical direction by a support shaft 12C that also projects from the stopper case 12a.

When the stopper 12 shown in FIG. 7 is in the operating state and the operating string 11 is pulled downward, the roller 13 is rotated and at the same time the gear 14 is pushed down along the step, as shown in FIG. , the operating string 11 is the roller 13
and the gear 14.

In this state, move the operation string 11 to the inner frame 2 below the screen 1,
The opening degree of the screen 1 can be freely adjusted by moving it downward against the weight of the presser frame 3 and the outer frame 4 or by moving it upward according to the weight.

When fixing the screen 1 after this adjustment, as shown in FIG. 9, after pulling the lower part of the operating string 11 in the direction of arrow A in the figure and bringing it into contact with the gear 14, Move the operating string 11 upward according to the weight of the frame 3 and outer frame 4 (
When the gear 14 is rotated (arrow B), the gear 14 moves upward (arrow D) along the stepped portion 12b while rotating in the direction of arrow C in the figure.
Eventually, as shown in FIG.
3 and gear 14, the screen 1 can be fixed.

Reference numeral 15 denotes an operation knob made of synthetic resin mixed with luminous dye, and inside thereof a pair of locking metal fittings 17, one end of which is rotatably supported by a locking fitting 16, are provided facing each other. As shown in FIG. 10, three operating strings 11 linked to the stopper 12 are tied to one side of the locking fitting 17, and one operating string 11 is tied to the other side. .

The locking fitting 17 prevents the operating string 11 from twisting.

Now, according to the pleated screen constructed in this way, the screen 1 is made of special synthetic Japanese paper, which moderately blocks direct sunlight from outside the window, softly illuminating the entire room, and blocks harmful infrared rays and ultraviolet rays. It absorbs a moderate amount of water and prevents fading and discoloration of indoor rugs, walls, furniture, etc.

Since it can be easily attached to a window curtain rail 10 using the main mounting bracket 5, auxiliary bracket 6, and support bracket 9, it can be installed in a room that does not have a sill, lintel, etc., and has the same lighting effect as a shoji. Therefore, it is possible to obtain effects that cannot be obtained with conventional blinds and curtains made of cloth, resin, metal, etc.

When replacing the screen 1, first loosen the bolts 7, remove the upper outer frame 4 from the main mounting bracket 5 and the auxiliary bracket 6, and remove the operating string 11 from the latch 11a.
Remove the tip and pull out the operating string 11 from the screen 1.

Then, from the upper and lower outer frames 4 to the inner frames 2. The screen 1 can be easily separated by removing the presser frame 3 in the reverse order as described above, and then removing the presser frame 3 from the upper and lower inner frames 2.

On the other hand, to assemble a new screen 1, the same screen 1 can be easily replaced by performing this procedure in reverse.

Therefore, by sandwiching and supporting both the upper and lower ends of the screen 1 with the inner frame 2, presser frame 3, and outer frame 4, this pleated screen eliminates the need to replace the paper unlike conventional shoji screens. 1 can be replaced quickly and inexpensively, and since the screen 1 is formed by bonding two sheets of synthetic Japanese paper together, it has superior durability compared to conventional shoji paper.

Note that this invention is not limited to the above-mentioned embodiments, but can also be implemented in the following embodiments.

(b) As shown in FIG. 14, the main mounting bracket 5 is directly fixed to the ceiling 20 with screws 21, and as shown in FIGS. 15 and 16, it is fixed to the wall 23 with screws 21 using a support bracket 22 to do.

(b) As shown in FIG. 17, an auxiliary frame 24 is provided in the center of the screen 1 that can move up and down independently of the upper and lower outer frames 4,
Divide the same screen 1 into two, vertically.

Thereby, it is possible to alleviate the uneven pitch of the folds 1a due to the weight of the screen 1.

(c) The screen 1 is made of non-woven fabric to obtain the same lighting effect as in the previous embodiment.

Effects As mentioned above, this invention provides a foldable screen 1 by providing horizontal folds 1a in paper or nonwoven fabric.
A plurality of rows of through holes 1b are provided in the center between the same fold lines 1a in the vertical direction on a straight line, respectively, so that the inner frame 2 can be fitted into each other,
The screen 1 is attached to the fitting part of the clamping member made of the presser frame 3.
Both upper and lower ends of the screen 1 are clamped, and the clamping members 2 and 3 are inserted into the outer frame 4, and at the same time, both upper and lower ends of the screen 1 are clamped and supported between the clamping members 2 and 3 and the outer frame 4. , multiple operating strings 1 with one end connected to the presser frame 3 at the bottom of the screen 1
