Description

[Detailed description of the invention] This invention relates to a shoji running device for a railless sash that does not have a rail on the lower frame, and its purpose is to make it easy to insert and remove the shoji and to open and close it in a stable state. It is.

As is well known, in the case of a sash that has a rail on the lower frame, dust and dirt tend to accumulate between the rail and the upright wall, or between the inner and outer rails, and it is difficult to remove this easily even if you try to remove it with a broom or vacuum cleaner. I couldn't. For this reason, recently a sash has been devised in which the lower frame has no rails and the lower part of the shoji is guided by a guide section provided on the lower frame, but if emphasis is placed on guiding the shoji, it becomes difficult to insert and remove the shoji. However, if emphasis was placed on fitting and removing the shoji, the shoji had the disadvantage of insufficient guidance.

Therefore, this invention devised a traveling device that pivots the wheel box of the door roller so that it can swing freely, and can guide the shoji by the lower frame guide part by floating the car box that swings down from the lower stile of the shoji. However, the drawbacks of conventional railless sashes have been completely improved.

Next, the structure of the shoji running device according to the present invention will be explained with reference to the drawings of the embodiment. 1 is a lower frame constituting the sash frame F, and the shoji insertion part of the lower frame 1 is connected to a smooth runway 1.
0, and a shoji guide part 2 is provided in parallel at the upper part of the indoor side of the runway 10, and the guide part 2 has an upright wall 21 that projects upward from the indoor side of the runway 10, and a wall 21 that extends from the top of the upright wall 21 to the outside side. It consists of a folded wall 22 that hangs down from the
A guide groove 23 that opens downward is formed between the standing wall 21 and the folded wall 22. 7 is Satsushi frame F
In the lower stile of the shoji which is inserted into the shoji, the inner wall 71 of the lower stile 7 is formed in a step shape toward the interior of the room, and an insertion hole 17 is bored in the rear part of the inner wall step part 72. 3 is a door roller attached to the shoji lower stile 7, and the door roller 3 has a flat roller 1 attached to the front of the wheel box 4.
3 is rotatably supported on a shaft, and the rear of the car box 4 is connected to a pin 14.
It is pivoted inside the outer box 6 or inside the shoji lower stile 7, and the car box 4
A guide piece 5 that is inserted from below into the guide groove 23 of the lower frame guide part 2 projects upward from the front part of the indoor side of the vehicle, and the rear part of the car box 4 is directly inserted into the lower frame 7 of the shoji. The guide piece 5 is inserted into the insertion hole 17 made in the inner wall step 72 of the shoji lower stile 7, or in the case of a double box type door roller 3', the guide piece 5 is inserted into the upper wall 61 of the outer box 6. An insertion hole 16 for the guide piece 5 is drilled, and the insertion hole 1
The guide piece 5 protruding from the lower frame inner wall 71 is inserted through the step insertion hole 17 of the lower frame inner wall 71. Reference numeral 15 denotes a protrusion provided at the tip of the guide piece 5. When the car box 4 swings down, the protrusion 15 is secured to the upper part of the upper wall 61 of the outer box 6, or is attached to the inner wall step of the lower stile 7 of the shoji. It is locked to the portion 72 to limit the swinging and lowering of the car box 4. 8 is the protrusion 15 of the guide piece 5
The locking piece 8 protrudes inward from the lower end of the rear of the outer box 7, or projects inward from the lower end of the shoji lower stile 7, and prevents the car box 4 from swinging downward. Restrict. A spring 9 is provided between the car box 4 and the outer box 6, and the spring 9 presses the car box 4 in the downward direction and prevents the car box 4 from falling beyond a certain level.

Since the shoji running device of the present invention has the above-mentioned structure, the runway 10 of the lower frame 1 that assembles the sash frame F is formed smoothly, and the shoji guide part 2 is provided at the upper part of the indoor side of the runway 10. The inner wall 71 of the shoji lower stile 7 to be fitted into this sash frame F is formed so as to form a step on the indoor side, and a door roller 3 is placed on the indoor side of the stepped portion 72 in advance.
An insertion piece 17 for the guide piece 5 provided in the front part of the car box 4 is bored. Insert the car box 4 of the door roller 3 from below into the door roller mounting position of the lower stile 7 that has been processed as described above. A guide piece 5 protruding upward from 4 is inserted and penetrated, and the rear part of the car box 4 is pivotally supported on the lower stile 7 by a pin 14, so that the front part of the car box 4 swings down about the pin 14. To support. In addition, when attaching the double box type door roller 3' to the lower stile 7 of the shoji, insert the double box type door roller 3' from below into the door roller mounting position of the lower stile 7, and insert the guide piece 5 of the car box 4 protruding from the outer box 6. The outer box 6 is fixed to the lower stile 7 with screws so that the front part of the car box 4, which is pivotally supported on the outer box 6, is swung downward. Keep it. In order to fit the shoji S with the door roller 3 attached as described above into the railless sash frame F, first insert the upper part of the shoji S deeply into the upper part of the sash frame F so that the lower part floats up, and then Door wheel 3 attached to stile 7
Since the rear part of the car box 4 is pivotally supported by the pin 14, the front part swings down by its own weight around the pin 14, and protrudes upward from the stepped part 72 of the inner side wall 71 of the lower stile. The guide piece 5 of the car box 4 that was
Or, it descends until it locks on the upper wall 61 of the outer box 6, or until the car box 4 locks on the locking piece 8 of the outer box 6. If the shoji S is moved toward the guide part 2 of the lower frame 7 with the guide piece 5 descending, the guide piece 5 has descended, so the stepped part 72 of the lower stile 7 is moved into the guide groove 23 of the guide part 2. It can be moved downward without any problem. After moving the guide piece 5 to the lower part of the guide groove 23, if the shoji S is lowered toward the runway 10 of the lower frame 1, the flat wheel 13 of the car box 4, which is swinging downward around the pin 14, will be removed. first touches down on the runway 10, so as the shoji S descends, the front part of the car box 4 swings and inserts into the lower stile 7,
As a result of the car box 4 swinging upward around the pin 14, the guide piece 5 provided at the front of the car box 4 protrudes from the car box 4 and passes through the step insertion hole 17 of the inner side wall 71 of the lower frame. Insert it into the guide groove 23 of the guide part 2 and move it to the runway 1.
In addition to guiding the door roller 3 running on the 0 top so that it does not swing inward or outward from the running direction, the stepped part 72 of the lower stile 7 is inserted to the bottom of the guide part 2, and the inner wall 71 of the lower stile 7 is guided.
approaches the lower frame upright wall 21 to improve airtightness between the lower frame 1 and the lower stile 7. When removing the shoji S that has been inserted as described above, when the shoji S is lifted upward and the lower stile 7 floats above the lower stile 1, the front part of the car box 4 whose rear part is pivoted on the lower stile 7 will be moved by its own weight. The guide piece 5 of the car box 4, which has been deeply inserted into the guide groove 23 of the lower frame 1, is moved downwardly by the car box 4, which swings downward as the lower frame 7 rises. As a result, the shoji lower stile 7 can be moved to the outdoor side through the guide part 2, and the shoji S can be removed from the sash frame F.

Therefore, since the shoji running device of the present invention runs the shoji along the smooth runway of the lower frame, rainwater does not collect on the lower frame, and there is little accumulation of dust or dirt. Even if dust etc. accumulates, the runway of the lower frame is formed smoothly and has no rails, so the dust etc. accumulated on the lower frame can be easily swept away and the sash lower frame can be kept clean at all times. In addition, the traveling device of the present invention pivots the rear part of the car box of the door roller, making the front part of the car box swingable, and also forms the inner wall of the lower stile of the shoji in a step-like manner toward the interior of the room. An insertion hole for a guide piece protruding from the front of the car box is provided so that the guide piece can be inserted into the guide groove of the lower frame when the car box is in the raised position, and removed from the guide groove when the car box is in the lowered position. In other words, as the shoji rises, the front part of the car box swings downward, and the guide piece provided at the front part sinks into the car box so that it can be inserted to the bottom of the lower frame guide groove, or While it can be taken out from the guide section,
As the shoji lowers, the front part of the car box swings and inserts into the lower frame, and the guide piece inserts into the guide part of the lower frame, so the shoji cannot be inserted into a sash frame with rails or inserted from the sash frame. The proposed shoji running device is remarkable for the practical use of rail-less sashes, as it can be inserted and inserted using the same means used to remove them, and there is no need to attach or remove guide pieces from the shoji each time the shoji is inserted or removed, unlike conventional rail-less sashes. This has the following effects.
