Description

[Detailed Description of the Invention] This invention relates to a lift-down window, and its purpose is to allow a screen door to be easily attached to the lift-down window so that it can be opened and closed easily.

Next, an embodiment of this invention will be described based on the drawings.

1 is an upper frame, 2 is a lower frame, 3 and 4 are left and right vertical frames, and these frames constitute a window frame. The upper frame 1 has a groove 5 opening downward in its outdoor side portion, and an intermediate horizontal frame 6 is placed with its longitudinal end abutted against the opposing surfaces of the left and right vertical frames 3 and 4 in their outdoor side portions. connected. The intermediate horizontal frame 6 has a groove 7 that opens upward. A glass plate 8 is mounted in a fitting manner via beads 9 and 10 using the groove 5 of the upper frame and the groove 7 of the intermediate horizontal frame.
Note that the left and right vertical sides of the glass plate 8 are the left and right vertical frames 3,
a stile 13 that is fitted and held by an intermediate protrusion 11 and a locking protrusion 12 on the opposing surface of the outdoor side portion of 4;
The rim 14 fitted into the frame, and the beat 1
It is also fixed to the left and right vertical frames via 5.

A sliding shoji 16 is installed on the indoor side of the window frame relative to the fixed glass 8. A guide rail 17 having a substantially L-shaped cross section is fixed to the indoor side portions of the left and right vertical frames 3 and 4, and a guide groove 1 is formed between the guide rail 17 and the intermediate protrusion 11.
8 and raise and lower shoji 16 in the left and right guide grooves.
The left and right vertical frames 19 are fitted together so as to be vertically movable.
Airtight members 20 and 21 are attached to the vertical stile 19 and come into contact with opposing surfaces of the intermediate protrusion 11 and the guide rail 17.

A rain cover 22 is also erected at the indoor end of the lower frame 2, and an airtight material 24 is attached to the upper end of the rain cover 22, which comes into contact with the lower stile 23 of the sliding shoji in a completely closed state.

25 has protrusions 26 and 27 at the bottom of the guide groove 18.
This is a lock receiving frame fixed by a lock receiving member, and holes 28 that open toward the opening surface of the guide groove are provided at required intervals in the height direction. Then, in conjunction with the operating lever 30 of the locking device 29 attached to the lower stile 23 of the raising/lowering shoji 16, the tip of the latch 31 that protrudes from both left and right sides of the raising/lowering shoji is inserted into the hole 28 of the lock receiving frame. It's now possible to stop. Put your hand on the handle piece 32 of the locking device and push the operating lever 30 to raise and lower the shoji, and when the force is removed from the operating lever at the desired height, the latch 31 will protrude due to the spring built into the locking device. By fitting the shoji into the hole 28, the shoji can be held at any desired height.

Moreover, a raising and lowering screen door 33 is built on the outside of the window frame relative to the fixed glass 8. Guide rails 34 and 35 are provided at the outdoor ends of the left and right vertical frames 3 and 4 and protrude from each other. Concave groove 3 of guide piece 38 installed in 37
9, the screen door 33 is held movably up and down without coming off from the window frame in the left and right direction. Note that when attaching the screen door to a window frame, the screw 40 that fixes at least one guide piece 38 to the vertical stile 36 is inserted into a horizontally long hole provided in the vertical frame. It has been moved to the back of 37 so that the screen door can be easily installed.

A locking protrusion 41 is protruded from the outdoor end of the lower frame 2, and when the screen door 33 is lowered, the lower stile 42 is stopped and supported by the locking protrusion 41. Also,
Since a rising surface 43 is formed at the indoor end of the locking protrusion 41, even if the screen door is exposed to strong winds, the lower stile 4
2 abut against its raised surface 43, thereby preventing the stile from being unduly bent and dislodged from the guide rails 34, 35.

A stopper 44 is attached to the lower surface of the intermediate horizontal frame 6 at approximately the center in the longitudinal direction. As shown in FIG. 3, this stopper 44 is slidably inserted into a case 45 fixed to the lower surface of the intermediate horizontal frame 6 with screws, etc., and into a long hole 46 provided through the lower surface of the case. a locking piece 49 that is slidably fitted into the groove 48 of the case and connected to the operation piece.
When the operation piece 47 is moved in the outdoor direction along the elongated hole 46, the locking piece 49 protrudes from the outdoor side surface of the intermediate horizontal frame 6 toward the outdoor side, and the operation piece When the locking piece 49 is moved toward the room, the locking piece 49 is retracted to almost the same level as the outdoor side surface of the intermediate horizontal frame or even closer to the indoor side.

In this way, after the screen door 33 is raised so as to overlap the fixed glass 8, the operation piece 47 is pushed toward the outdoor side, and the locking piece 4 is moved as shown by the chain line in FIG.
When the screen door 9 is projected, the screen door is held in the open position by the stopper 44 even if the hand is removed from the screen door.
Further, after supporting the lower side of the screen door with a hand and pulling the operation piece 47 toward the indoor side, the user can lower the hand supporting the screen door and close the screen door by its own weight.

As in the above embodiment, guide rails are provided protruding from the left and right vertical frames, and these are fitted to both the left and right vertical frames of the screen door.
When holding the screen door so that it can be raised and lowered, there is no need for the window frame and the screen door to have a complicated structure. However, instead of fitting the guide rail into the screen door vertical frame, the means for holding the screen door in a vertically movable manner may be such that a groove is provided in the vertical frame to fit the screen door vertical frame in a vertically movable manner.

As described above, according to this invention, a raising/lowering screen door can be easily provided on the outdoor side of a raising/lowering window, and a stopper for stopping the screen door in an open state can also be easily attached.
