Description

[Detailed explanation of the idea] The present invention relates to a height-adjustable screen door.

This will now be described with reference to the accompanying drawings, in which one embodiment is shown.

The height adjustment in this invention is achieved by installing a movable column 1 inside the lower stile as shown in Fig. 2A for a screen door consisting of a lower stile 2, an upper stile 3, and left and right short roots 5 shown in Fig. 1. By inserting the movable column 4 into the upper stile and moving it up and down, or by inserting the movable column 4 into the upper stile and moving it up and down as shown in the same side opening.
It is also possible to use both of them together, but the principle is the same except that the explanatory words are more complicated.
A case in which an operating portion is provided in part A of FIG. 1 will be explained.

The vertical operation of the movable column as described above is performed by operating the operation box 6 including the operation rod 11 shown in FIGS. 2 to 4. In these figures, the horizontal wall 2a of the lower stile 2
An operating box 6 is fixed on the top, and an operating rod 11 housed in the iron surface is slidably passed through the horizontal wall 2a in the vertical direction and is provided at the bottom of the rod. It is fixed to the horizontal wall 1a of the movable column 1 slidably inserted into the lower stile 2 by a hook 12.

Although not shown, this movable column is usually attached to a door roller so that the screen door can be moved onto the lower frame.

The upper part of the operating rod 11 is located inside the box 6, and a knob 10, which is integrally attached to the operating rod, is exposed to an operating hole 6a provided in the operating box by means of a spout 15.

Further, the upper end of the operating rod has a pawl 14, which engages with saw teeth or notches 13 provided in the operating hole 6a.

In other words, when a person pinches the knob 10 with the tips of his fingers and pushes it inward, the engagement between the claw 14 and the notch 13 is released, and the rod 11 can freely move up and down within the vertical allowable range of the operating hole 6a. .

Since the movable column 1 is fixed to the lower end of the rod 11, the movable column 1 can also be moved up and down at the same time, which means that the height of the screen door can be adjusted.

When the desired height is adjusted and the fingertip is released from the knob 10, the claw 14 is re-tightened by the restoring force of the spring 15.
, so unless this guarantee is canceled, the
In other words, it is adjusted and the height does not change.

In the figure, the rod 11 is shown as a flat plate made of metal, for example, and the upper part thereof is vertically divided into two parts, one of which is used as a spring 15, and one of which is provided with a knob 10 and a pawl 14. It may be in the shape of a rod instead of a flat plate, and the spring 15 may be made as a separate body.

The crosspiece 1 and the rod 11 may be fixed by welding or the like instead of using the hook 12.

The material of the rod itself is not limited to stainless steel or steel, but may also be made of plastic.

Next, an example of fixing the operating box 6 including the operating rod 11 as described above to a screen door will be described with reference to FIG.

That is, the horizontal wall 2a of the lower stile has a through hole 16 for the rod 11, and the horizontal wall of the movable column inserted into the lower stile also has the rod 11.
A mounting hole 17 is provided.

Move frame 1 to frame 2 so that these 16 and 17 are aligned vertically.
In the screen door assembled with the short roots 5, the groove 18 provided in the operation box 6 and the rib 23 provided in the short roots 5 are fitted, and the box 6 is pressed downward.

When the tip of the rod 11 passes through the through hole 16 and is pushed into the mounting hole 17, the hook 12 bites into the horizontal wall 1a, and the lower end of the rod 11 is fixed thereto.

Note that the fitting between the groove 18 and the rib 23 alone is unstable, so if the lower surface shape 19-20 of the operating box 6 matches the upper shape 21-22 of the lower frame 2, the operating box will be more stable. It is fixed on the lower stile.

Although the lower stile was illustrated above, the movable column 4 of the lower stile 3
A diagram obtained by interpolating is shown at the beginning of Figure 2.

In this case, it is sufficient to read the upper and lower parts of the operating box and operating lever as opposites.

Of course, the crosspiece 4 will probably be equipped with a stopper 9 instead of the door roller.

In Fig. 2, the symbol 8 is an insect-proof packing made of rubber or plastic, which has a cross-sectional shape that expands outward from the frame, and which is attached to the frame surface or the sash. By placing it in close contact with the outer stile, it covers the gaps that occur between the stile and the frame, thereby preventing insects from entering.

In another embodiment, if only the bottom operation box is provided due to price restrictions, screws 7 indicated by 7 may be installed at the top.
Therefore, if the movable pillar 4 installed inside the upper stile 3 is used in a fixed manner, the purpose can be achieved.

[Brief explanation of the drawing]

The attached drawings show one embodiment of the screen door of the present invention, in which Fig. 1 is a front view thereof, Fig. 2 is an enlarged perspective view of part A in Fig. 1, and Fig. 3 is an operating box equipped with an operating rod. Exterior perspective view, 4th
The figure is a sectional view taken along the line AB in FIG. 3 including the lower rail, and FIG. 5 is a perspective view for explaining the installation of the operation box. In the figure, 1 and 4 are movable columns, 2 is a lower stile, 3 is an upper stile, 5 is a short root, 6 is an operating box, 10 is a knob, 11 is an operating lever, 13 is a notch, 14 is a pawl, and 15 is a spring. .
