Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the Invention (Industrial Field of Application) The present invention is a method for adjusting the spacing between light shielding members such as blinds and curtains to uniform or non-uniform pitches. This invention relates to a pitch control tool.

(Prior art) In general horizontal blinds, a plurality of slats are supported by a ladder cord formed in the shape of a ladder, but the ladder cord also has the function of uniformly controlling the pitch between each slab. are doing.

Further, in vertical blinds, pitch control is performed by attaching a metal fitting to a cord extending in the horizontal direction and fixing the slab L to this metal fitting.

Under such backwarming conditions, the present applicant has proposed a pleat which is: formed from a pleat-like material in which horizontally elongated trailing light members and non-light blocking members are arranged alternately in the vertical direction. We have previously filed a patent application for this type of curtain (Japanese Patent Application No. 268885-1985).

In this curtain, if the connecting portion between the light blocking member and the non-light blocking member is strong, the light blocking member etc. will not fall even if the ladder cord as described above is not used, and the pitch can be maintained to a certain extent. be controlled.

(Problems to be solved by the invention) However, even in the pleated type curtain,
When the light shielding member becomes larger or lff1 increases,
Due to its own weight, the pitch between the light shielding members in the upper part becomes wider than that in the lower part, so it becomes necessary to perform pitch control.

As a means of controlling the pitch, there are two methods: ■ Sewing thread or tape to each light shielding member so that the distance between each light shielding member is equal, or ■ Making a cut in the tape and attaching a thin composite material to each light shielding member in this cut. Although means such as inserting a resin piece may be considered, either method has the problem that it is not easy to assemble the pitch control tool to the light shielding member.

Structure of the Invention (Means for Solving the Problems) Therefore, in order to solve the above-mentioned problems, the present invention provides a light shielding device that is inserted into a plurality of light shielding members provided in a light shielding tool and adjusts the pitch between the light shielding members. A technical measure was taken in which the control tool consisted of an elongated body and a locking protrusion formed in the middle of the elongated body.

(Function) Since the pitch control tool of the present invention consists of an elongated body and a locking protrusion formed in the middle thereof, an insertion tool such as a needle is attached to one end of the pitch control tool.
The pitch control tool can be easily accommodated in the light shielding member by simply threading it through the light shielding member.

The light shielding member into which the pitch control tool is inserted is locked by the locking protrusions, and arranged at a pitch corresponding to the pitch of the formation positions of the locking protrusions.

(Example) Hereinafter, an example embodying the present invention will be described based on FIGS. 1 to 9.

As shown in FIGS. 2 and 3, the light shielding tool 1 of this embodiment consists of a pleated member P in which horizontally long light shielding members 2 and similarly horizontally long non-light shielding members 3 are alternately connected in the vertical direction. It is formed. The pleat-like object P has a nearly trapezoidal front surface, and its shape is such that two parallel rod-shaped support bars 4 are placed at a predetermined interval on the light-shielding member 2 and the non-light-shielding member 3. It is maintained by inserting it through the center of the vertical width.

The upper and lower ends of each support bar 4 are
An upper support plate 5a and a lower support plate 5b are respectively attached to maintain the interval between the pleats P.
is designed to prevent it from bending laterally.

Then, by locking a locking member (not shown) attached to the upper part of the light shield 1 to the upper support plate 5a and lowering the lower part of the light shield 1, the light shield 1 is expanded. By removing the locking member, the light shielding tool 1 can be folded toward the lower support plate 5b. The two support plates 5a and 5b can be attached to and removed from the support bar 4, and the support bar 4 can also be removed from the light shielding device 1.

Between the two support bars 4, two pitch control tools 6 are inserted through the light shielding member 2 and the non-light shielding member 3 at a predetermined interval.

As shown in FIGS. 1, 4, and 9, the pitch control tool 6 is composed of a long body 7 made of polyamide monofilament and a locking protrusion 8 formed in the middle thereof. Parts of the light shielding member 2 are locked to the locking protrusions 8 at a predetermined pitch.

The locking protrusion 8 is made of a sheet piece or molded body that is flexible enough not to damage the light shielding member 2, and the pitch control tool 6 can be inserted into the light shielding member 2 in one direction, but not in the other direction. It has a crooked shape that makes it impossible to insert it. Further, the locking projection 8 is provided with a widening portion 8a that can be elastically deformed in the direction of the arrow X with respect to the center side of the elongated body 7 (see FIG. 9).

This pitch control tool 6 is manufactured, for example, as follows. First, as shown in FIG. 5, the elongated bodies 7 are stretched substantially parallel to the grooves 10 formed in the opposing members of the bottomed frame member 9 at predetermined intervals.

Next, as shown in FIG. 6, an ultraviolet curing resin R1, such as an epoxy acrylate resin, is injected and cast onto the bottom member 12 of the frame member 9 to a thickness equal to the diameter of the elongated body 7. Then, as shown in FIG. 7, the elongated body 7 is covered with a black mask 14, and the groove portion 10
A presser jig 11 is placed inside the frame member 9 in which the frame member 9 is formed.

Then, as shown in FIG. 8, the elongated body 7 sinks into the ultraviolet curing resin R, and the mask 14 is superimposed on the surface of the ultraviolet curing resin R. In addition, the mask 14 has a parallel plate at the same interval as the elongated body 7,
Further, V-shaped ultraviolet transmitting portions 13 are formed at the same intervals as the pitch of the light shielding member 2.

When the UV curable resin R thus masked is irradiated with UV rays, the UV rays pass through the UV transmitting portion 13 and hit the UV curable resin R. Then, the ultraviolet curable resin R is exposed to light and cured, and at the same time, the cured portion is fixed to the elongated body 7.

As a result, as shown in FIG. 9, a pitch control tool 6 is obtained in which locking protrusions 8 are fixed to the elongated body 7 at predetermined intervals in a creeping manner.

Next, regarding the function and effect of this embodiment) When the pitch control tool 6 is hoisted, a needle (not shown) is passed through the tip of the pitch control tool 6, and the pitch control tool 6 is moved into the structure shown in FIGS. 2 and 3. It is inserted into the light shielding member 2 of the light shielding tool 1 so as to pass through the center of its vertical width. Then, the upper part of the pitch control tool 6 is fixed to the upper support plate 5a so that the light shielding member 2 is caught on the locking protrusion 8.

The number of pitch control tools 6 to be inserted into the light shielding member 2 may be at least one, and the insertion point is at the center of the width of the light shielding member 1, but in this embodiment, two pitch control tools 6 are inserted into the light shielding member 2. It is inserted through the light shielding member 2 and the non-light shielding member 3 at intervals.

Then, the light shielding tool 1 in which the pitch control tool 6 is inserted through the light shielding member 2 is obtained (see FIGS. 2 and 4).

In this light shielding tool 1, even if the light shielding members 2 are large or relatively heavy, the pitch between the upper light shielding members 2 will not be wider than that of the lower part due to their own weight. do not have. Therefore, if the light shielding member 2 is exposed to direct sunlight and the non-shading member 3 is not exposed to direct sunlight, if both are arranged in a diagonal shape and tilted as necessary when installed near a window, the light shielding member 1 will block direct sunlight. .

Further, by simply forming an insertion hole (not shown) that is slightly larger than the elongated body 7 in the light shielding member 2 of the light shielding tool 1, the pitch control tool 6 can be inserted into the light shielding member 2 and the light shielding tool 1 can be easily inserted into the light shielding tool 1. It can be tackled. Incidentally, when the light shielding member 2 is made of a fiber fabric or a woven material, it is not necessary to form the insertion hole in the light shielding member 2.

The light shielding tool 1 with the pitch control tool 6 assembled is installed near a window where light shielding is required.The light shielding tool 1 of this embodiment has a pleated structure in which horizontally long light shielding members 2 and non-light shielding members 3 are alternately connected in the vertical direction. Since it is composed of a shaped object P, especially when attached to the rear window of a car,
Demonstrates a unique effect.

That is, the light-shielding member 2 prevents direct sunlight from entering the interior of the vehicle, and the non-light-shielding member 3 allows the outside of the vehicle to be seen through from inside the vehicle and makes it difficult to see the interior of the vehicle from outside the vehicle. Therefore, the light shielding member 2 of this embodiment is not only opaque enough to completely block light, but also transparent or transparent to the extent that the outside of the vehicle can be seen from inside the vehicle after blocking light to some extent. It's better to go.

The present invention is not limited to the above-mentioned embodiments, and can also be implemented, for example, in the following embodiments.
