Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding type mesh door in which a net folded in a bellows shape is openably and closably mounted in a mesh door frame. The present invention relates to improvement of a mechanism for locking an operating frame for operation.

[0002]

2. Description of the Related Art As a screen door whose net can be opened and closed,
Conventionally, a foldable screen door that is folded in a bellows shape and has a retractable net attached to the screen door frame so that it can be freely opened and closed,
Well known.

In such a folding screen door, it is necessary to engage both ends of the net with the screen frame and the operating frame for opening and closing. As a structure for that purpose, a conventional structure is disclosed in, for example, Japanese Unexamined Patent Publication No. 5-179875. As disclosed, a plate-like locking member (support member) is provided at the end of the net.
, And the locking member is inserted into the locking groove provided in the screen frame and the operating frame (slide bar) to be locked. However, since the above-mentioned conventional locking member is composed of a single plate, it is very troublesome to bond a coarse material such as a net to one surface of the plate with an adhesive, and the bonding strength is comparative. Since the size of the net is small, it has a drawback that the net is easily peeled off when a tensile force is applied to the net when the net is opened and closed. Further, when the bellows-shaped net is opened and closed while expanding and contracting, the locking member swings in the locking groove and collides with the groove wall, which easily causes noise.

[0004]

SUMMARY OF THE INVENTION The main object of the present invention is to easily and firmly fix an end of a net in a folding mesh door with an engaging member for engaging the end with a screen frame or an operating frame. To be able to do it. Another object of the present invention is to prevent the locking member from colliding with the locking groove wall and generating noise when the net is opened and closed.

[0005]

In order to solve the above problems, the folding screen door of the present invention is provided with an end portion of a net folded in a bellows shape, and the end portion is used as a screen door frame or an operating frame for opening and closing. A pair of right and left holding parts made of hard synthetic resin and a bending part made of soft synthetic resin for connecting the holding parts to each other are provided with locking members for locking. The holding member is bent into two at the position of the bent portion to allow the end portion of the net to be held between the two holding portion pieces, and the both holding pieces to be connected to each other via the net. It is characterized in that it is fixed to the end of the net by adhering to. According to a specific configuration aspect of the present invention, a locking groove is formed in the screen frame or the operating frame, and the locking member is inserted and locked in the locking groove. In the above case, it is desirable that the bent bent piece of the locking member also serves as a buffer member that causes the locking member to abut on the groove wall of the locking groove in a buffer manner. According to a preferred configuration aspect of the present invention, the bent portion piece of the locking member is formed thinner than the pair of holding portion pieces, and is provided at a position biased to the outer surface side of both holding portion pieces. There is.

[0006]

The above-mentioned locking member is bent in two at the position of the soft bending portion to hold the end portion of the net between both the hard holding portion pieces and to bond the both holding pieces to each other. As a result, since it is fixed to the end portion of the net, the locking member can be easily and firmly fixed even to a net made of coarse material. By inserting the locking member into the locking groove, the end of the net to which the locking member is fixed is
It is locked to the screen frame or the operating frame. Even when the locking member swings in the locking groove due to the expansion and contraction of the bellows-like net during the opening / closing operation of the net, a collision with the groove wall is avoided by the buffering action of the soft bent portion. No noise is generated.
Further, since the bent portion piece of the locking member is formed thinner than the holding portion pieces and is provided at a position biased to the outer surface side of both holding portion pieces, the locking member is bent in two. At some times, the bent piece is bent in a gently curved state, so that a sufficient cushioning function can be achieved.
