Abstract

A punching type sliding folding door is provided in an entrance for ventilating (cold air) with the entrance door slightly opened.
In this shutter, each slat is independent and slides sideways so that the folding width can be reduced. Taking advantage of this feature, even if it is installed in the entrance, it is a sliding door that does not interfere with people coming and going. Further, punching was performed for each slat so that ventilation (cold air) could enter even when locked. This makes it possible to safely open the front door, which has been a problem in crime prevention. A net was put on the punched hole so that insects could not enter.

Description

The present invention relates to a blind shutter, and more particularly, to a punching blind door that opens or closes by a bending-extending link.

In summer, especially when the front door is slightly opened, cold air flows into the room and there is no need for a cooler. However, there was a problem in crime prevention when the front door was opened.

As a means for solving such a problem, there is a punching type sliding folding door.
This punching type sliding folding door is constructed by suspending a plurality of plate-like slats communicated by bending and extending links from an upper sash so as to be movable along the upper and lower sashes.
When the folding door link is extended along the sash, the plurality of slats face the front of the plate and the folding door closes, while the slat surface is ventilated by providing many holes. It can be carried out.
Moreover, since this punching type sliding folding door is folded when it is opened or closed, it can be opened or closed with a slight force.

As such a punching type sliding door, a blind type resin shutter disclosed in Patent Document 1 has been proposed. In the blind type resin shutter disclosed in Patent Document 1, a plurality of slats are inclined at a predetermined angle from the front of the shutter and are parallel to each other, and the slats are opened with the shutter closed. Thus, a certain amount of light shielding and ventilation can be performed while the door is closed. In addition, the blind type resin shutter is easily attached to a house by reducing the weight of the mounting member and simplifying the mounting method using an adhesive tape or the like.

(Punching type sliding folding door)
FIG. 1 is a vertical cross-sectional view of a punching type sliding folding door in the embodiment of the present invention when the door is opened.
Moreover, FIG. 2 is a cross-sectional view when the door is opened in the present embodiment, and shows a cross section taken along the line AA of FIG.
The punching type sliding folding door is made of, for example, a resin, and a large number of holes 100 are formed through the surface thereof.

In addition, it is preferable that this hole part is a circle | round | yen, a square, etc. whose diameter is about 10-20 mm. This is because if the diameter of the hole 100 is formed extremely large, the effect of daylighting and ventilation is enhanced, but the inside of the door 19 can be visually recognized from the outside, and further, the effect of the crime prevention surface is also reduced. It is.
In addition, the number of formed holes 100 per unit area and the forming sensation can be appropriately changed according to the purpose and application.

FIG. 3 is a diagram showing the surface side of the aforementioned folding door guide frame 20.
As shown in the figure, the folding door guide frame 20 is formed in a quadrilateral shape with respect to the opening 2.
Further, the folding door guide frame 20 has an upper frame 21 that constitutes the upper side of the quadrilateral, a lower frame 22 that constitutes the lower side, and a pair of left and right vertical frames 23 that constitute the side. Configured.

FIG. 4 is a front view of the punching type sliding folding door 19. FIG. 6 is an enlarged perspective view of the punching type sliding folding door 19.
As shown in the figure, the blind folding door 19 guides a plurality of slats 38 formed in a strip shape, a telescopic ledge 41 that connects the upper and lower ends of each slat 38, and the upper ledge 41. A guide roller 42 that is rotatably supported in the rail 39 via a guide hole 40, and a guide that movably engages the lower ledge tong 41 in the guide rail 39 of the lower frame 22 via the guide hole 40. And a pin 43.

The slat 38 is constituted by an elongated plate body, and the ledge tong 41 is attached to the upper and lower ends.
The slat 38 has a locking edge 44 that is bent in opposite directions at both side end portions, and a concave groove 45 is formed in the locking edge 44 along the vertical direction. An elongated sealing member 46 (for example, a rubber material) is fixed to the concave groove 45 to improve water tightness when the locking edges 44 of the slats 38 are in close contact with each other.

In addition, the ledge tong 41 is configured to expand and contract in an expander manner by hinge-joining a plurality of sets of two types of links 47a and 47b having different shapes that are axially attached at the center and rotatably combined in an X shape. .
The link 47a constituting the ledge tong 41 is constituted by a plate (one of which the bending angle is gently set) in which one of the links 47a is bent in a circular cross section.
The link 47b is formed of a plate that is bent in an L-shaped cross section. The upper and lower ends of the slat 38 are fixed to the link 47b.

Problems that the device tries to solve

Ventilation (cold air) enters when you open the entrance, but it becomes completely visible from the common hallway and there is a problem in crime prevention.

Means for solving the problem

The present invention is safe because the slat can be ventilated for punching even if the door is closed while locked.

Effect of device

The effects of the present invention are as follows: (1) Ventilation (cold air) passes (2) The room is difficult to see from the outside.
(3) It is safe because it is locked. ▲ 4 ▼ Because the screen door is covered, insects do not enter.
