Description

[Detailed description of the invention] This invention relates to a double window shoji that can be easily installed and removed at home.

Recently, windows have been made to have a double layer structure to prevent cold air from entering through the windows and preventing warm air from escaping. However, double glass and double sash shoji screens are expensive, are a financial burden, and are not easy to install, making it impossible to attach them to existing windows as needed.

Therefore, the present invention utilizes the screen rails installed on existing windows to easily fit a large number of miniaturized auxiliary shoji to create a double structure window, and after the winter season, the auxiliary shoji can be removed. It is intended to replace the original window shoji. That is, the double window shoji of the present invention has the following four types (a) to (d) on the screen rail of the window frame, the width of which is less than half of the width of the existing single window shoji. It was fitted using auxiliary shoji.

(a) A plurality of auxiliary shojis having grooves formed on one end surface and protrusions that fit into the grooves on the other end surface.

(b) A concave groove identical to the auxiliary shoji in (a) above is bored on the left end surface, a protrusion is extended on the end surface along the outdoor side surface on the right side, and a locking hook is rotated on the indoor side surface. One auxiliary shoji that is movably attached.

(c) A groove similar to that of the auxiliary shoji in (a) above is bored on the right side end surface, a protrusion is extended on the left side along the outdoor side surface, and a locking hook is rotated on the indoor side surface. One auxiliary shoji that is movably attached.

(d) The auxiliary shoji is divided into upper and lower members, a protruding strip is provided on one of the divided surfaces, a groove is provided on the other, and they fit removably, and the above (b) is attached to both the outdoor side surfaces of both the upper and lower members. and (c), forming a stepped part that engages with the protrusion of the auxiliary shoji, and providing pins on both indoor side surfaces that engage with the locking hooks of the auxiliary shoji of (b) and (c) above.
Auxiliary shoji.

Next, the operation of the present invention will be explained based on the embodiments shown in the drawings. Fig. 1 is a view from the indoor side showing a state in which the auxiliary shoji of the present invention are connected, and four types of auxiliary shoji are combined. The width of each type of auxiliary shoji is smaller than 1/2 of the width of the existing window shoji, and rail engagement grooves are bored in the upper and lower end surfaces.

Reference numeral 1 denotes an auxiliary shoji having a groove 2 formed in the vertical direction on one end face, and a protrusion 3 extending in the vertical direction that fits into the groove 2 on the other end face.

4 is provided with the groove 2 on the left end surface, and on the right side is provided with a protrusion 5 extending along the outdoor surface and on the end surface, and locking hooks 6, 6 are mounted on the indoor side surface. This is a movable auxiliary shoji.

Reference numeral 7 designates an auxiliary shoji which has the groove 2 formed on its right side end face, and has a protrusion 5 similar to the auxiliary shoji 4 and locking hooks 6 on its left side.

8 is an auxiliary shoji consisting of an upper member 9 and a lower member 10, and the joint surfaces of both members have grooves 1 that engage with each other.
1 and a protrusion 12, it can be attached and detached freely.

Further, step portions 13 that engage with the projecting edge 5 are formed on both end surfaces of the members 9 and 10 on the outdoor side, and pins 14 and 14 that lock the hooks 6 and 6 are provided on both side surfaces of the indoor side. ing. Note that gaskets 15, 15 are attached to the bottoms of the grooves 2, 11.

Thus, a plurality of auxiliary shoji (in the example, two shoji) as described in 1 above. A second shoji is formed on the existing screen door rail using one each of 4, 7, and 8 auxiliary shoji.

First, fit the auxiliary shoji 1 into the screen door rails 16, 16 in the same way as a regular shoji fits into the rails, drill the groove 2 and move it to the side (left), then the groove 2 and the screen door will fit together. It fits into the left side protrusion provided on the vertical stile on the same vertical plane as the window rail to prevent gaps from forming with the window frame. Next, the concave grooves 2 of the next auxiliary shoji 1' are fitted into the convex strips 3 of the auxiliary shoji 1, and the shoji 1 is fitted into the screen door rails 16, 16. And an auxiliary shoji 4 having a groove 2 that fits into the convex strip of the auxiliary shoji 1'
Then, the auxiliary shoji 7 having the groove 2 that fits into the right side protrusion of the vertical stile is inserted into the screen door rails 16, 16, respectively.

Furthermore, when the lower member 10 of the auxiliary shoji 8 is fitted into the spaces of the auxiliary shojis 4 and 7 and the hooks 6 and 6 are rotated to engage the pins 14 and 14, the outdoor side is connected to the protruding edges and bottom of the auxiliary shojis 4 and 7. Since the step portion 13 of the member 10 is engaged, the lower member 10 and both the auxiliary shojis 4 and 7 come into contact with each other without any gap. In the same manner, the upper member 9 is fitted between both the auxiliary shojis 4 and 7, and both upper and lower members 9 and 10 are fitted.
Since the second shoji is connected by the concave groove 11 and the protruding strip 12, the second shoji is formed as a whole by being completely fitted to the screen rail of the window frame, forming a double window shoji.

As mentioned above, each auxiliary shoji that makes up the proposed double window shoji is less than half the width of the existing shoji,
It is lightweight and easy to handle, and even if it is a two-panel shoji, the auxiliary shoji can be easily installed and removed from the indoor side in a space with one shoji open, and the auxiliary shoji can be installed outside. This makes it convenient to work in high places, especially on the second floor or higher.

Since the existing screen door rails are used, no special construction work is required, and auxiliary shoji or screen doors can be attached as needed.

Since each joint part is fitted with a concave groove and a convex strip, it is possible to prevent a gap from occurring and the connection is strong.

In addition, since the auxiliary shoji 8 to be installed last engages with the protruding edges 5 of the auxiliary shoji on both sides through the step portions provided on both sides of the outdoor side, it is possible to create a shoji that fits completely without creating a gap. Furthermore, by dividing the shoji 8 into two upper and lower members and fitting the lower member first, the fitting gap can be secured and fixed, so the upper member can be easily fitted and the work will not be difficult. .

By fixing the shoji with hooks, the entire auxiliary shoji becomes as strong as one piece.
