Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blinding member that is attached to a mounting base of a screen door or the like to block strong sunlight during the day and see-through from the outside.

Conventionally, this type of blindfolding member has been made by clamping and fixing the blades together with a net using a U-shaped jacket, connecting each blade with a string, and changing the angle by pulling the string. A screen door with a similar structure has been proposed.

However, if the blades attached directly to the net are moved up and down, there is a problem in that the net is likely to be pulled and damaged due to the movement of the blades.

In addition, as a technique of this type, a cylindrical portion is formed by protruding semicircular plate portions from both ends of both side plates constituting the wind control blade, and rubber is inserted into the cylindrical portion, and the rubber inside the cylindrical portion is There is a technology for a variable wind direction louver in which the cylindrical part is fitted into a bearing part so as to press the wind control blade, so that the wind control blade is kept stationary at an arbitrary inclination angle (Japanese Utility Model Publication No. 49-44756).

However, since blinding members attached to screen doors, etc. need to be removed from the window frame and stored together with the screen door etc. when not in use, they must be made as thin as possible so that they can be stored. It becomes necessary to support it in a cantilevered manner.

For this reason, it is difficult to keep the blades of the blindfold main body stationary at a desired angle of inclination simply by increasing the frictional resistance between the rotating shaft and its bearing, so it is difficult to keep the blades of the blindfold main body stationary at an arbitrary inclination angle. I couldn't.

In view of this, the present invention comprises an angle adjustment mechanism for preventing the free rotation of the blades of the blindfold body from a tightening rod having a threaded portion and a screw hole into which the threaded portion is screwed, To provide an angle-adjustable blindfold member that allows a mechanism to act between a receiver attached to a mounting base of a screen door or the like and an end of a blindfold body, thereby solving the above-mentioned problems. It is.

Hereinafter, the content of the present invention will be described in detail based on embodiments shown in the accompanying drawings.

The blinding member attached to the mounting base of the screen surface of screen door A is formed into a flat plate using a synthetic resin plate such as vinyl chloride or a light metal plate such as aluminum. a blindfold main body 1 having a wing portion 2 that protrudes from the outside and blocks strong sunlight during the day and visibility from the outside;
It is comprised of a catch 6 for attaching the blindfold main body 1 to the mounting base of the screen door A.

A cylindrical support part 3 is integrally formed on the root side of the blindfold main body 1 over the entire length in the longitudinal direction, and a cylindrical support part 3 is integrally formed on the base side of the blindfold main body 1, and a cylindrical support part 3 is formed at both ends thereof in opposite directions on the axis of the support part 3. A protruding rotating shaft 4 is provided in a protruding manner.

Further, the catch 5 for attaching the blindfold main body 1 to the mounting base of the screen door A is made of synthetic resin, metal, etc. and has an oval shape in cross section, and one side wall of the fixture 5 is attached to the screen door A by means of fastening means such as pins. The other side wall serves as a bearing portion 6 through which the rotating shaft 4 rotatably passes.

The angle adjustment mechanism B, which allows the blade part 2 of the blindfold main body 1 to stand still at an arbitrary inclination angle, is connected to the rotating shaft 4, which has a threaded part 8 carved on its surface and has a function as a fastening rod 7. The nut 10 is screwed onto the distal end side of the rotating shaft 4 that passes through the bearing part 6 of the stopper 5. By tightening the nut 10 with the bearing part 6 interposed between the bearing part 6 and the end face of the blindfold body 1, free rotation of the blade part 2 of the blindfold main body 1 is prevented, and the blade part 2 is kept stationary at an arbitrary inclination angle.

FIG. 4 shows a modification of the first embodiment, in which screw holes 9 for an angle adjustment mechanism B are provided at both ends of the support portion 3 of the blindfold main body 1, and The tightening rod 7 of the angle adjustment mechanism B is composed of a bolt 11 that also functions as the rotating shaft 4 when its threaded portion 8 is partially screwed into the screw hole 9, and this modified example In this case, the blindfold main body 1 can be easily removed from the catch 5 by removing the bolts 11, which is extremely convenient for storing and cleaning the screen door A and the blindfold member.

Next, in the blinding member of the second embodiment shown in FIGS. 5 and 6, unlike the case of the first embodiment, the bearing part 6 of the catch 5 is formed in a cylindrical shape, and the peripheral wall thereof A screw hole 9 constituting the angle adjustment mechanism B is bored on the surface side, and the threaded portion 8 of the tightening rod 7 of the angle adjustment mechanism B, which is composed of a bolt 11, is screwed into the screw hole 9. When tightened, the tip of the tightening rod 7 rotates around the rotating shaft 4 which rotatably passes through the bearing section 6.
is pressed to prevent its rotation, thereby keeping the blade portion 2 stationary at an arbitrary inclination angle.

7 and 8 show a modification of the second embodiment, in which the bearing portion 6 is formed into a cylindrical shape with a split end, and the rotary shaft 4 is rotatably inserted into the bearing portion 6 from the end thereof. A threaded portion 8 is carved on the outer peripheral surface of the base side of this bearing portion 6, and has a function as a tightening rod 7 of the angle adjustment mechanism B, and also has a screw hole of the angle adjustment mechanism B. 9 is the threaded part 8 of the bearing part 6
It consists of a long nut 12 that is screwed into the rotary shaft 4 to tighten the rotating shaft 4.

Furthermore, the blinding member of the third embodiment shown in FIGS. 9 to 11 differs from the above embodiments in that the bearing part 6 of the catch 5 has an inclined guide hole 13. Form each catch 5
A support rod 14 that supports the blade portion 2 of the blindfold main body 1 on its lower surface side is disposed between the bearing portions 6, and an angle adjustment mechanism B is configured at both ends of the support rod 14 in the axial direction thereof. A screw hole 9 is bored, a bolt 11 is used as the fastening rod 7 that slides through the guide elongated hole 13, and its threaded portion 8 is screwed into the screw hole 9, and the bearing portion 6 is inserted between the bolts 11. By tightening the bolts 11, the support rod 14 is fixed at an arbitrary position, thereby supporting the blade portion 2 at an angle of inclination.

12 and 13 show a modification of the third embodiment, in which a screw hole 9 is formed below the bearing portion 6 of the stopper 5 and extends vertically. The tip of the threaded portion 8 of the tightening rod 7 passing through the screw hole 9 is placed against the lower surface side of the blade portion 2 of the blindfold main body 1, and by rotating this tightening rod 7, the tension of the blade portion 2 is adjusted. It is used to adjust the

As described above, the blindfold member of the present invention has a fastening rod having a threaded portion between the receiver and the end of the blindfold main body, and a screw hole into which the threaded portion of the fastening rod is screwed. An angle adjustment mechanism is provided, and this angle adjustment mechanism allows the blades of the blindfold body to remain stationary at any desired inclination angle.By loosening the screw connection of the angle adjustment mechanism, the blades can be rotated easily. The blade can be rotated extremely smoothly without applying much force to the mounting base such as the screen surface of a screen door, and if the screw connection of the angle adjustment mechanism is tightened at a predetermined angle Even when the blindfold main body is mounted in a cantilevered manner to a mounting base of a screen door or the like using a retainer, the blade portion is reliably held at the inclination angle.

For this reason, when changing the inclination angle of the blades of the blindfold body, there is no need to apply excessive force to the mounting base of the screen door and damage the screen surface. Since it can be kept stationary, it is possible to freely adjust the amount of light and airflow, and it is also possible to effectively prevent viewing from outside depending on the surrounding environment.

In addition, since the angle adjustment mechanism is constituted by a screw connection between a tightening rod and a screw hole, the structure of the catch can be simplified, and the blinding member can be manufactured at low cost.
