Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a screen door device with a double-raised and lowered sash.

Conventional technology For example, as described in Japanese Utility Model Application Publication No. 140700/1983,
A screen door guide groove is provided on the outdoor side of the vertical frame, and a screen door shoji is vertically movably engaged with the screen door guide groove, and when this screen door shoji is raised and positioned near the upper frame of the window frame, There is a structure in which a locking piece for receiving a screen door shoji is provided on a middle crosspiece that forms a fitting part so as to be able to protrude freely.

Problems to be Solved by the Invention In the conventional example, when the insect-proofing effect of the screen door shoji is expected, the screen door shoji is lowered and used, and when this is not needed, it is raised and overlapped with the fitted part. Because of this, the opening of the shoji is limited to one location, and due to the positional relationship of the locking pieces, it can only be used for one-sided up/down sashes.

Items that can be used for raising and lowering both sides include:
There is a method described in Japanese Utility Model Application Publication No. 58-37397, but since the method described in this publication has a pair of inner and outer screen door shoji configured in a so-called sliding type, a corresponding width is required. First, even if it is possible to increase the ventilation effect by providing shoji openings at two locations above and below the window frame, the inside and outside screen shoji overlap each other in the indoor-outdoor direction, which is not desirable in terms of lighting.

The present invention has been devised for the purpose of providing a screen door device with both raising and lowering sashes that eliminates the drawbacks of the conventional example.

Means for Solving the Problem In a double-raised and lowered sash constructed by assembling a pair of inner and outer shoji on a window frame, a screen door guide groove is provided on the outdoor side of the inner and outer shoji of the vertical frame, and a screen door guide groove is provided in the screen door guide groove. An upper screen door and a lower screen door that overlap each other along the screen are engaged so as to be vertically movable, and each stile of the upper and lower screen doors is provided with a locking piece that can freely protrude in the direction of the screen door guide groove, corresponding to each locking piece. The receiving piece is provided at the inner end of the screen door guide groove when the upper and lower screen doors are brought into contact with each other and raised toward the upper frame of the window frame.

Embodiment The drawing shows an embodiment of a screen door device with double-raised and lowered sashes according to the present invention.

In the diagram, 1 is the inner shoji, 2 is the outer shoji, and the inner and outer shoji 1,
2 are of the same size and can be placed at appropriate positions in the vertical direction of the window frame A by means of a balancer device 4 housed in the vertical frame 3 of the window frame A.

Reference numerals 5 and 5' denote a pair of upper and lower screen doors of the same size, and an L-shaped elastic piece 8 fixed to the upper stile 9b of the lower screen door 5' with a screw 7 is inserted into a groove 10 provided in the lower stile 6a of the upper screen door 5. The screen doors 5 and 5' are press-fitted into each other so that they can be releasably joined to each other, and the screen doors 5 and 5' are press-fitted into each other so that they can be separated from each other.
5' is made to be the same size as the inner and outer shoji 1 and 2.

11 is a locking piece provided on the lower stile 6a of the upper screen door 5;
The locking pieces 11 are accommodated in both ends of the lower stile 6a with their tips protruding freely in the direction of the vertical frame 3, and the pieces 11' are made to protrude outside through long holes 16 provided in the lower stile 6a. Entering and exiting operations are performed by operating the . Moreover, this locking piece 11 is attached to the upper stile 9 of the screen door 5'.
They are also provided at both ends of b in the same manner as described above.

Reference numeral 12 denotes a receiving piece fixed with a screw 14 to the inner end of the screen door guide groove 13 formed in the vertical frame 3;
The above-mentioned locking pieces 1 provided on the upper screen door lower stile 6a and the lower screen door upper stile 9b, respectively, when both the screen doors 5, 5' are brought into contact and joined and raised toward the upper frame 14.
They are arranged at positions corresponding to numbers 1 and 11.

Therefore, in the embodiment, both the screen doors 5, 5' are raised toward the upper frame of the window frame in the joined state, and the locking pieces 11, 11 are made to protrude and are received by the receiving pieces 12, 12. Then, the screen doors 5, 5' close the upper opening when the inner and outer shoji 1, 2 are lowered toward the lower frame 15 (FIG. 5b).

In addition, when the inner and outer shoji 1 and 2 are arranged in the middle position of the window frame A, the upper screen door 5 is locked with the receiving piece 12 in the above-mentioned state, and the lower screen door 5' is separated from the upper screen door 5. By lowering it toward the lower frame 15,
The insect-proofing effect can be obtained by closing the openings formed on the upper and lower sides of the inner and outer shoji 1 and 2 with the upper and lower screen doors 5 and 5'.
Alternatively, the ventilation effect can be increased.

The lower stile 6a of the upper screen door 5 and the lower stile 6b of the lower screen door 5',
The locking pieces 11 are arranged on the upper stile 9a of the upper screen door 5 and the upper stile 9b of the lower screen door 5', and on the upper stile 9a of the upper screen door 5 and the upper stile 9b of the lower screen door 5', respectively. The guide groove 13 may be provided with receiving pieces 12 corresponding to each of these patterns.

In addition, there are various other possibilities that can be considered when implementing the present invention, and even if the size of the screen door is different from each other, or the size of the inner and outer shoji is different, the screen door can be set at any position. be.

Effects of the invention Since the present invention has the above-mentioned configuration, the screen door can be set arbitrarily. Therefore, by setting the shoji and the screen door in an appropriate size relationship, window openings can be freely set in the summer. You can choose the position.

In addition, since the upper and lower screen doors are arranged so as to overlap each other along the screen guide groove, the expected width does not become particularly wide, and the screen doors do not overlap in the indoor/outdoor direction, which improves lighting. The disadvantages of can be prevented.
