Description

[Detailed Description of the Invention] (1) Field of Industrial Application This invention relates to a sliding shoji window in which the shojis are located on the same plane in the closed position, and one shoji can move freely within the window frame when opened. Specifically, the present invention relates to a shoji moving device for a double-sliding shoji window that moves the other shoji from the closed position and moves the other shoji to a double-sliding position with the one shoji so that it can be moved.

(2) Conventional technology Sliding shoji windows, in which the shoji are flush when closed, differ from regular sliding shoji windows in that they have various features.
Therefore, one shoji is allowed to run freely within the window frame, the other shoji is supported by an arm pivoted to a running body that runs within the window frame, and one shoji is allowed to run freely at the sliding position of the other shoji. The technique of moving the shoji to the closed position flush with one shoji by rotating the arm is disclosed in Japanese Utility Model Application No. 58-75878, Japanese Patent Application Publication No. 59-55975, and Japanese Patent Application Publication No. 59-91281. , Utility Model Application Publication No. 58-75879. In all of these technologies, the shoji is supported by an arm pivoted at one point of the running body, moved to the closed position where it is flush with the shoji, and supported in that state, and the total weight of the shoji is Since the load is almost always borne by the arm, the twisting and bending of the arm and the frictional force at the pivot joint are large, making it difficult to rotate the arm smoothly.

(3) Problems to be solved by the invention (a) During the movement of the shoji to the sliding position and during the return process to the flush position, the load on the shoji that is borne by the pivot part of the arm is minimized, and To smoothly move and run a shoji by reducing the load.

(b) When the shoji is stopped flush, the weight of the shoji should not be concentrated on the pivot point of the arm.

There are two points.

(4) Means for solving the problem The running bodies, each with its own arm pivotally connected, are joined together by a connecting rod, and the door rollers of each running body are pivoted on the base that supports them along the running direction. Two rollers are arranged side by side, and the arm is formed wide enough to ensure contact with each roller on its lower surface even in the rotating position, and the roller rotates as the arm rotates. The base has a cam piece that is pivotally supported so as to be able to protrude and retract from the plane of the lower surface of the arm, and the cam piece is biased so that its top part protrudes from the lower surface of the arm, and the rotation of the arm is caused by the attitude of the cam piece. It is designed to restrain and maintain a constant sliding state. A stop member is provided protruding from the window lower frame surface, and as the traveling body moves, the cam piece hits and rotates and engages with the stop member, and the top of the cam piece descends from the lower surface of the arm, so that the above-mentioned locking of the arm is prevented. Once released, the arm can rotate freely and return to a position flush with the other shoji. The reciprocating rotation of the arm always causes the rollers to rotate, and the load of the shoji is shared by the rollers, and ultimately by the base.

(5) Example To explain the example in detail based on the drawings, Fig. 1 is a front view of the interior when the two shoji are in a flush position, and Fig. 2 is a horizontal sectional view taken along line A-A. and shown in FIG. FIG. 6 is a BB vertical side view of the same. As shown in Fig. 6, the upper and lower window frames 1a,
Cavities 4a and 4d are formed in 1d to accommodate running bodies 5a and 6a and 5d and 6d. Upper running body 5
A, 6a are provided with guide rails 61a, 62a in the upper space 4a, and lower traveling bodies 5d, 6d are provided with guide rails 61d, 62d in the lower space 4d. As shown in FIGS. 3 and 7, while the shoji 2 moves back and forth linearly within the window frame 1, the shoji 3 is supported by upper and lower arms 8a, 9a and 8d, 9d. Main axis 10, 11 in the body
It is pivoted at. As shown in FIGS. 8 to 11, the hollow base 14 of the traveling body is a member having an inverted U-shape in cross section and consisting of front and rear side walls 15 and 16.
Door wheels 8, 20, 22 and 19, 21, 23 are pivotally connected. Respective running bodies 5a, 6a and 5d, 6d
are connected together by a connecting rod 7, and can travel while maintaining a constant distance. Since the pivoting structure of each arm to the traveling body is all the same, the traveling body 6d will be explained. An arm 9d is rotatably attached to the upper surface of the base 14 of the traveling body 6d by a main shaft 11. As shown in FIG. 9, one half of both side walls 15, 16 is cut out in the longitudinal direction to provide an opening 24, in which two rollers 27, 28 are arranged side by side. The rollers 27 and 28 are arranged on opposite walls 2 in the longitudinal direction.
5 and 26, and contacts the lower surface of the arm 9d in a flush state and a rotating state, and the arm 9d
The rotation of the rollers 27 and 28 causes both the rollers 27 and 28 to rotate. The other end of the arm 9d is pivotally attached to the mounting base 36 of the lower stile 3d of the shoji 3 at a pivoting portion 13d. Similarly, the arm 8d of the traveling body 5d is rotatably attached to the main shaft 10. The other end of the arm 8d is connected to the shaft attachment portion 1.
It is pivotally connected to the lower stile 3d by a shaft attachment part 12 with an interval equal to the distance between the main shafts 10 and 11 with respect to the main shaft 3d. Arm 8 pivotally connected to upper traveling bodies 5a, 6a
Similarly, a and 9a are pivotally attached to the upper stile 3a of the shoji 3 at the same interval using pivot attachment portions 12a and 13a. The shoji 3 has these four upper and lower arms 8a, 9a and 8d, 9d.
Supported by Thus, the distances between the arms 8d, 9d and the shafts 10, 11 of each traveling body and between the shaft attachment parts 12, 13 form a parallelogram. A protrusion 30 is provided on the base 14 on the opposite side of the roller group across the main shaft 11. The arm 9d rotates from the shoji flush state and its linear side edge 31 hits this protrusion 30,
It serves as a stopper that does not allow further rotation in the direction C shown in FIGS. 8 and 11. The roller side of the arm 9d forms a notch 35 that comes into contact with a surface of a cam piece 32, which will be described later. As shown in FIGS. 11 and 13, a cam piece 32 is rotatably interposed between the two rollers and is mounted on a shaft 59 to the side walls 15 and 16. The cam piece 32 is formed into an almost inverted L shape, and has a long leg piece 5.
5 and a horizontal head 56, and the shaft 59 is located approximately at the intersection of the two. The head 56 has a flat top 5
6a and inclined portions 56b and 56c on both sides thereof, forming a Mt. Fuji shape, and the tip thereof forms a downward hook-shaped portion 57. The leg piece 55 has an inward protrusion 55a at the lower end and is biased to stand upright by a spring 58.
As shown in Figures 0 and 14, when the leg piece 55 is upright, the flat top part 56a protrudes from the through hole 17 in the base surface.
The arm 9 is locked into the notch 35 of the arm 9d.
d is prevented from rotating in the D direction. As a result, the shape of the parallelogram formed by the main shafts 10, 11 arms 8d, 9d and the shoji lower frame does not deform even when force is applied in the direction of arrow A or B, respectively, as shown in FIG. Upper and lower running bodies 5a, 6a and 8
d and 9d move in the direction of arrow A or B, and the shoji 3 smoothly moves to an arbitrary sliding position. On the other hand, a stop member 60 that can be engaged with the cam piece 32 is provided on the window lower frame 1d surface.
The traveling body 6d is moved from the state shown in FIG.
When traveling in the direction of arrow E, the cam piece 32 hits the slope 60a of the stop member 60 at the position shown in FIG. In the next step, the inward protrusion 5 at the lower end of the cam piece 32 is shown in FIG.
5a is locked to the stop member 60, and the leg piece 55 rotates against the spring 58 using that point as a fulcrum, and the hook-shaped portion 57 at the tip of the head is attached to the slope 60b of the back of the stop member 60.

The inclined part 56b of the head part a is separated from the cutout part 35 of the arm 9d and is on the same plane as the lower surface 29 of the arm 9d, so that the arm 9d can rotate in the D direction. If you push the shoji 3 toward the outdoor side, the lower arm 5
The rollers 27 and 28 of the traveling body which are in contact with the lower surface 29 of d and 6d support the arms 5d and 6d and
The shoji 2 shown in FIGS. 5 and 8 realizes smooth rotation of all arms in the D direction while rotating in the
move to the closed position flush with the When in this position, the arm 9d is in the position shown in FIGS. 12 and 15, and the inclined portion 56b of the cam piece 32 is in contact with the lower surface 29 of the arm 9d, so the cam piece 32 is engaged with the stop member 60. The running body 6d cannot move in either the left or right direction, and even if force is applied to the shoji 3 in the direction A or B, the shoji does not move, ensuring the shoji closed position shown in Fig. 5. do.

(6) Effects of the Invention The present invention has the above-mentioned configuration, in which two running bodies supporting a shoji that moves from a flush position to the rear indoor side by an arm are integrally connected by a connecting rod. Therefore, its operation is reliable, and the weight of the shoji 3 is borne by the upper and lower arms 8a, 9a and 8d, 9d, but most of the load is borne by the lower arms 8d, 9d. Since the arm is required to maintain contact with the rollers arranged in parallel, it is formed in a wide shape, maintains contact with the roller even in the rotating position, and is supported by at least one end of the indoor roller 28. As a result, the load on the arm and therefore on the shafts 10 and 11 is reduced, and rotation by the arm becomes smooth. Since the rollers bear part of the load of the arms 8d and 9d while running, the arms do not twist or twist like conventional arms without roller support.
Inconveniences such as bending can be prevented. Even when the shoji is flush, the base bears the entire weight of the shoji via the arms and rollers, greatly reducing the burden on the main shaft.
