Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor side of a fitting and killing portion of a window frame having an upper portion as a fitting and killing portion and a lower portion as an opening.
The present invention relates to a screen door device of a raising and lowering sash in which a shoji for opening and closing an opening is vertically movable.

2. Description of the Related Art A guide rail composed of vertical frame pieces is provided on a blind side of a blind-fitting outdoor side, and a guide rail composed of vertical frame pieces is provided, and a screen door is attached to the guide rail. I have to.

[0003]

According to the conventional example, since the guide rail is specially provided, the prospective width of the window frame is inevitably widened, which is even more promising in the case of the double glazing system ups and downsashes. As a result of the wider width, it may be difficult to install in relation to the building and the screen door may have to be omitted.

The present invention has been made in view of such a conventional example, and was devised for the purpose of providing a screen door device which does not require a particularly wide prospective width of the window frame in order to install the screen door.

[Means for Solving the Problems] A raising and lowering sash in which a sliding door for opening and closing an opening is vertically movable on the indoor side of the fitting and killing portion of a window frame having an upper fitting portion and a lower opening portion. Provided at the outdoor end of the vertical frame that constitutes the fitting and killing portion of the frame and the opening portion, a protruding piece that protrudes inward of the window frame is provided, and upper and lower locking pieces that slidably contact the indoor side surface of the protruding piece are provided on the screen door. The structure is such that it projects in the direction of the indoor side.

1 is a longitudinal sectional view, FIG. 2 is a partially enlarged transverse sectional view, and FIG. 3 is a sectional view taken along the line aa in FIG. FIG. 4 is a partially enlarged front view in which a window frame is omitted, FIG. 5 is a sectional view taken along line bb of FIG. 4, FIG. 6 is a front view of a screen door, and FIG. 7 is a perspective view of a lower locking piece.

In the lifting and lowering sash of the embodiment, the shoji B for opening and closing the opening A2 is vertically movable on the indoor side of the fitting and killing part A1 of the window frame A having the upper part as the fitting and killing part A1 and the lower part as the opening A2. It is configured as a device.

The screen door C is arranged on the outdoor side of the window frame A so as to correspond to the shoji B, and the upper locking pieces 2 and 2 and the vertical frame provided at the middle portion of the upper frame 1 of the screen door C in the left-right direction. Lower locking pieces 4 and 4 provided on the lower side of 3 are provided on the outdoor ends of the vertical frames 5 and 5 of the window frame A, and on the indoor side surfaces of the projecting piece pieces 6 and 6 that project inward of the window frame. The screen door device according to the embodiment is assembled by being brought into sliding contact with each other.

The upper locking piece 2 is formed by projecting a locking piece 8 having an L-shaped cross section on the indoor side of the mounting piece 7, and the mounting piece 7 is superposed on the upper frame 1 and screwed. 9 is fastened and attached to the upper frame 1 of the screen door C as described above, and the engaging portion piece 8 of the upper engaging piece 2 is hooked on the fitting killing portion 6a of the protruding portion piece 6 of the vertical frame 5. As described above, it is in sliding contact with the indoor side surface of the fit-and-kill portion 6a.

The lower locking piece 4 is composed of a slightly L-shaped body when viewed from the front, and the lateral piece is the locking piece 10 and the vertical piece is the gripping piece 11. , 11 are rotatably pivotally attached to the vertical frame 3 by screws 12 and the locking piece 10
Is slidably contacted with the indoor side surface of the opening side portion 6b so as to be hooked on the opening side portion 6b of the protruding portion piece 6 of the vertical frame 5.

The lower locking piece 4 is locked by the protrusion 13 provided on the outdoor side surface of the handle portion piece 11 to be locked in the locking groove 14 formed on the indoor side surface of the vertical frame 3 so that the lower locking piece 4 can rotate. It is regulated.

Then, the screw 12 is loosened, the ridge 13 is disengaged from the locking groove 14, and the lower locking piece 4 is rotated to remove the locking portion piece 10 from the opening side portion 6b of the protruding portion piece 6. The screen door C can be removed from the window frame A by rotating the whole in the finding direction, and the assembling may be performed in the reverse order.

Further, the screen door C can be arranged at a desired height position by the upper and lower engaging pieces 2 and 4 contacting the indoor side surface of the projecting piece 6.

The lower locking piece 4 is pivotally attached to the vertical frame 3 with a screw 12, but a rivet may be used instead of the screw 12, and the rivet is used to tighten the lower locking piece 4 like the screw 12. Eliminates the need for tightening and removing

Reference numeral 15 shows a stopper.
