Description

[Detailed Description of the Invention] This invention relates to a folding screen door that can be easily attached to a door with a door check used for openings such as back doors and entrances without any trouble.

Conventionally, curtains or folding screens installed at openings such as entrances, back doors, etc., have devices such as door checks or door stoppers attached to the pan surface of the door. Because it causes trouble in the use of
The rails that guide the curtains and screen door cannot be attached, and if they are forced to attach, part of the folding screen door will have to be removed.
Therefore, there were problems in that it was very unsightly and the insect-proof blindfold effect was extremely incomplete.

Therefore, in order to solve these conventional drawbacks, this invention was developed by attaching a hanging wheel at the upper part of the folding screen door at a predetermined interval.A guide rail for suspending the hanging wheel is provided at the upper part of the door opening. The guide rail is constructed of corresponding rails consisting of a straight portion and a curved portion, and each straight portion of the rail is inserted and contracted directly or via a straight rail. It was characterized by the fact that

Therefore, a door or the like equipped with a door check of an automatic opening/closing device or the like can be installed with good appearance without causing any hindrance, and the insect-proofing effect and the blinding effect can be sufficiently closely related.

Furthermore, since it is extendable, the width can be freely adjusted, and the left and right curved parts allow the device to be used in either the left or right mounting position of the door check.

Next, one embodiment of this invention will be explained with reference to the drawings.
The folding screen door 1 has hanging wheels 17, 17 provided at a predetermined interval on the upper part.
The guide rail 2 is folded and opened/closed by .

The guide rail 2 is composed of large and small rails 3 and 4 each having a straight portion 5 and a curved portion 6.

The straight portions 5.5 of the rails 3 and 4 are fitted in a telescopic manner.

Reference numeral 7 denotes a shielding plate made of wood or the like, on the lower surface of which the guide rail 2 is attached, and which also serves as a canopy that covers the upper surface of the guide rail 2.

Next, sliding grooves 8, 8 are provided in the straight portion 5 of the rail 3, and a locking protrusion 9 that engages with the sliding grooves 8, 8 is forced onto the straight portion 5 on the opposite side.

Reference numeral 10 indicates a door equipped with a door check 11, 12 is a stud for attaching the end of the folding screen door 1, and 13 is a fixture for fixing the shielding plate 7 to the stud 12.

14 is a guide frame when opening and closing the folding screen door 1;
1 is a gap prevention material that prevents gaps and serves as an insect repellent, and 16 is a straight rail interposed between each rail 3, 4.

This device has the above-mentioned configuration, and to explain how to use this device now, the shielding plate 7, which serves as a canopy, is fixed to the studs 12, 12, etc. using fixtures 13, 13.

The guide rail 2 is attached to the shielding plate 7 by expanding and contracting to fit the width of the opening.

As shown in FIG. 2, even if the door check 11 is installed on the door 10, the arm of the door check 11 can open and close without contacting the folding screen door 1.

According to this invention, the guide rails are expandable and retractable, so the dimensions between the columns can be adjusted freely, and both ends of the opposing rails are formed into curved parts, so the effect of not getting in the way of door checking and the relative relationship between the rails. Since the straight parts facing each other are telescopically inserted and contracted, there is no need to cut the rail, which simplifies the work.

Furthermore, since the guide rail is composed of a plurality of rails each having a straight portion and a curved portion, the guide rail is strong against bending, and the curved portions located on the left and right sides make it possible to adjust the left and right hand positions of the door check. It has the excellent effect of being able to be freely attached to any object.

In addition, the shielding plate located on the top of the guide rail facilitates the installation of the guide rail, reliably prevents insects from entering, prevents dust from falling from the ceiling, and prevents light items from falling. It has a great effect of being able to be mounted.
