DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind-up screen device such as a wind-up insect screen or a blind, the screen of which can be freely opened and closed by rotation of a wind-up shaft.

[0002]

2. Description of the Related Art In general, a movable frame is attached to the end of a screen wound around a winding shaft, and the screen is opened and closed while guiding the movable frame and the left and right ends of the screen to guide rails, respectively. The opening and closing operation of the screen device is performed by a handle protruding and attached to the front side of the movable frame.

[0003] However, when the opening and closing operation is performed by the handle, the movable frame is prevented from tilting in the front-rear direction to prevent both ends of the movable frame from being scooped in the guide rails, and the movable frame is maintained in a normal posture. Since both ends of the movable frame need to be moved in parallel along the guide rails, the opening / closing operation is performed by placing a finger on the base of the mounting portion of the handle, that is, a portion as close as possible to the holding portion of the screen in the movable frame. In many cases, a screen made of a relatively weak material may be worn or deteriorated at a portion where a finger contacts, and the screen may be broken from that portion.

[0004]

SUMMARY OF THE INVENTION The technical problem of the present invention is to prevent a finger from touching the screen at the opening and closing operation of the screen in the movable frame to prevent the finger from coming into contact with the screen. An object of the present invention is to suppress the abrasion and deterioration of the holding portion of the screen.

[0005]

According to the present invention, a movable frame is attached to the end of a screen wound around a winding shaft, and the movable frame and the left and right ends of the screen are respectively mounted on guide rails. In the wind-up screen device wherein the screen is opened and closed while being guided, the movable frame comprises a frame main body, and a cover member for holding a lower end of the screen between the frame main body and the movable frame. A portion for holding the screen between the cover member on the upper surface and a protective wall for preventing fingers from contacting the screen during opening and closing operations of the screen,
It is characterized by being erected along the front surface of the screen.

[0006] In the folding type screen device having the above structure, the protective wall is provided upright along the front surface of the screen at a portion where the screen is sandwiched between the movable frame and the cover member at the upper end of the frame body. In addition, the fingers do not come into contact with the screen during the opening / closing operation of the screen, and the abrasion and deterioration of the screen are suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 3 show the present invention applied to an insect screen which is a kind of a wind-up screen device. An example of the case is shown.

As shown in FIG. 1 and FIG. 2, the insect screen door is provided with a winding box 2 attached along an upper frame member of a building opening, and is rotated around a horizontal axis inside the winding box 2. A take-up shaft 6 freely supported and provided with a rotational force in a take-up direction by using a biasing force of a spring 4 disposed therein as a drive source, and a take-up end wound around the take-up shaft 6 A screen 8 made of an insect-proof net derived from the slit 2a on the lower surface of the box 2;
A movable frame 12 provided with a handle 10 for opening and closing operation on the front side facing the room, and standing vertically downward from both ends of the winding box 2 to open and close the screen 8 It comprises a pair of left and right guide rails 14 for guiding the screen 8 and the left and right end portions of the movable frame 12 during operation.

As shown in FIG. 3, the guide rail 14 is provided with a main rail 16 which opens toward the side of the screen 8 and is held in the main rail 16 so as to be movable in the width direction thereof. The inner rail 18 is provided with a slit 18a that opens toward the side in the longitudinal direction.

[0010] Locking members 22 are respectively attached to the left and right side edges of the screen 8 along the longitudinal direction of the screen 8, and the locking members 22 are locked in the slits 18 a of the inner rail 18. Inserted and locked. The locking member 22 is arranged along one side edge of a main body 22a made of cloth or synthetic resin in a tape shape.
Locking piece 22 slidably locked in the slit 18a
b, the base end side of the main body 22a is connected to the screen 8.

As shown in FIG. 2, the movable frame 12 has a frame main body 24 made of an extruded aluminum material.
And a cover member 26 made of synthetic resin for holding the lower end of the screen 8 between the frame body 24 and the frame body 24. A protective wall 24a is provided along the front surface of the screen 8 at the portion where the screen 8 is sandwiched between the screen 8 and the cover member 26 on the upper surface of the frame main body 24.
This prevents the fingers from touching the screen 8 when the screen is opened and closed. In addition, the said protective wall 24a is the frame main body 2
4 and may be separate.

In the drawings, reference numerals 26a and 26b denote cushion members made of a flexible synthetic resin integrally provided on the upper and lower surfaces of the cover member 26, respectively. When the screen 8 is opened and closed, the movable frame 12 is brought into contact with the lower frame of the opening of the building or the lower surface 2b of the winding box 2 in a buffered manner. In the drawing, reference numeral 28 denotes an engaging portion 2 provided at the lower end of the guide rail 14 at the stretched position of the screen 8 where the movable frame 12 is pulled down to the lowermost position.
0 is an engagement mechanism that removably engages with the engagement mechanism 2.
8, the guide wall 14a on the front side of the guide rail 14 is sandwiched between the projecting piece 30 and the movable frame 12 to guide the movable frame 12 up and down by the guide wall 14a.

In the above-described embodiment, the present invention is applied to a wind-up screen device which is automatically opened and closed by a spring 4 disposed inside a wind-up shaft 6. The present invention is not limited to this, and is applied to a screen device configured to wind an operation cord or the like around a pulley provided at one end of a winding box, and to feed out and wind up the screen with the operation cord or the like. You can also.

In the insect screen door having the above structure, fingers are generally likely to be lost at the base of the handle 10 for smooth operation of the movable frame 12, but the cover member at the upper end of the frame body 24 of the movable frame 12 is generally used. 26, the protection wall 24a is provided upright along the front surface of the screen 8 at the portion where the screen 8 is sandwiched. Therefore, the abrasion and deterioration of the screen 8 can be suppressed.

[0015]

As described in detail above, according to the folding screen device of the present invention, a protective wall is provided at a portion of the movable frame where the screen is sandwiched between the upper surface of the frame body and the cover member. Since it stands along the front of the screen,
Fingers can be prevented from contacting the screen during the opening / closing operation of the screen during the opening / closing operation of the screen, whereby wear and deterioration of the screen holding portion of the movable frame can be suppressed.
