Description

[Detailed description of the invention] [Industrial application field] This invention consists of several shojis arranged in the same plane in a frame, and at least one of each shoji closed on the same plane. This type of sliding shoji is opened in a sliding manner along rails after being moved in parallel toward the indoor side, and relates to a device for moving the sliding shoji indoors.

[Conventional technology]

This type of conventional shoji moving device has operating rods arranged around the frame of the shoji all around, and by turning a handle provided on the shoji, the operating rods move linearly, and this linear movement is converted into rotational movement. This mechanism moves the shoji in parallel to the indoor side. However, as the handle rotates, the conversion mechanism releases the locking means for the frame of the shoji in the initial section and moves the shoji in the second half of the rotation. It is necessary to move the shoji to a position where it can be slid without being interfered with by other shojis, and it is necessary to apply a large amount of force. Consideration is given to reducing resistance. The conversion mechanism also needs to be designed to have little sliding resistance and to keep the shoji immobile while the shoji is unlocked.

[Problem that the invention attempts to solve]

By the way, as mentioned above, in order to reduce the sliding resistance of the operating rods, etc., the engagement of each member is loosely formed, but loose engagement causes backlash, and when the shoji is unlocked. the conversion mechanism is activated;
This causes the defect that the shoji shoji shakes.

In order to solve the above-mentioned problems, this invention provides a sliding shoji moving device that reduces sliding resistance, prevents the shoji from swinging, and enables reliable locking and unlocking. It is in.

[Means for solving problems]

The solution based on this invention consists of an operating rod that is provided around the shoji that runs along the rails of the frame body and moves linearly back and forth; a link that is movably engaged in the running direction of the shoji through rollers; In a sliding shoji moving device that engages with a guide hole consisting of a folded hole portion continuous with a long hole portion and bent toward the pivot axis, a protruding strip is provided on the operating rod to form a link when the shoji is in a closed state. A guide pin is protruded from the link so as to be parallel to the elongated hole of the guide hole, and a guide pin that comes into contact with the indoor side surface of the protruding strip is protruded from the link. This is because it is formed to a length that makes contact with the.

[Effect]

According to the above structure, the engagement of the operating rod into the stile is formed loosely, and the engagement of the operating pin with the link guide hole is formed loosely, so that even if the operating rod is moved from the closed state of the shoji, the link Since the guide pin moves along the protrusion of the operating rod, swinging of the operating rod and link is prevented and the lock is reliably released.

〔Example〕

Figure 3 is a front view of the sliding sash seen from the indoor side, and on the left side of the frame 1 in the figure is a shoji 2 that is opened and closed in a sliding manner after moving in parallel to the indoor side.
The shoji 3 fixed on the right side are housed in parallel to each other, and the movable shoji 2 has a handle 4 on the door stop stile 2a, and an operating rod 5 is installed in the stile around the four sides as shown schematically by dotted lines. Rotation of the handle 4 causes an operating rod 5 to move linearly and reciprocally, and this movement sequentially links the locking and moving operations of the shoji 2 with respect to the frame 1.

Figures 4 and 5 show the state in which the moving shoji 2 is closed within the frame 1 and the state in which it has moved.
The main structures of the frame 1 and the shoji 2 related to the device of the present invention will be explained. A guide groove 6 having a downward opening is provided over the entire length on the indoor side (right side in the figure) of the upper frame 1a. A rail 7 running on the shoji 2 is provided on the indoor side of the lower frame 1b. Further, support grooves 8 and 9 are provided along the entire length of the upper and lower stile 2c and 2d of the shoji 2 on opposite sides of the frame 1, and the left and right vertical stile 2a and 2b also have support grooves 8 and 9, although not shown. Grooves are provided, and the operating rod 5 is slidably fitted into each of these bearing grooves 8 and 9. Moreover, the shoji 2 has a door roller 10 that runs on the rail 7, and the door roller 10 has one casing 10.
A is equipped with two wheels.

Therefore, the sliding shoji moving device according to the present invention is shown in FIGS.
A bypass portion 5a that escapes from the support groove 8 and detours toward the indoor side is provided in the middle portion of the upper frame 2c, and a bearing 11 is fixed to the upper surface of the upper stile 2c.
A link 12 that overlaps parallel to the upper frame is rotatably mounted on a horizontal plane by a pivot 13, and the link 12 is a roughly triangular plate, and a roller 14 that stands up from the tip of the link 12 is attached to the upper frame 1a. It protrudes into the guide groove 6. Further, a guide pin 16 and a regulating pin 17 are provided extending toward the center from an end of the link 12 that is different from the end where the pivot shaft 13 and roller 14 are provided. The guide hole 15 is inserted into the shoji 2 as shown in FIG.
In the closed state, a guide hole 15 extending in the longitudinal direction of the bypass section 5a is bored, and a pivot shaft 13 is formed following the straight elongated hole section 15a parallel to the bypass section 5a.
A folded hole portion 15b is provided which bends toward.
On the other hand, an operating pin 18 that loosely fits into the guide hole 15 with a diameter smaller than the width of the guide hole 15 is provided in the bypass portion 5a.
The bypass section 5a is provided with a protruding strip 19 that contacts the guide pin 16 of the link 12, so that when the shoji 2 is moved from the closed state shown in FIG. During the forward movement, the guide pin 16 comes into contact with the indoor side surface of the convex strip 19, and this abutting side surface is inclined so as to gradually protrude toward the indoor side in the direction of the arrow 20. Since the abutment surface is formed into the above-mentioned sloping surface, the shoji is reliably pushed toward the outside of the room, so locking and unlocking can be performed reliably. Further, as the actuating rod 5 moves in the direction of the arrow 20, the actuating pin 18 and the protrusion 19 also move in the direction of the arrow 20, but the actuating pin 1
8 reaches the end of the elongated hole portion 15a, the protrusion 19 is disengaged from the guide pin 16.

While the actuating pin 18 reaches the end of the elongated hole 15a, the guide pin 16 is restricted along the protrusion 19, so the actuating pin 18 moves straight and the link 12
The link 12 remains stationary without applying any operating force to the frame 1 of the shoji 2.
A lock (not shown) is released. When the actuating pin 18 advances further, it comes into pressure contact with the inner wall of the perforated portion 15b, and a torque is applied to rotate the tip of the link 12, which is provided with a roller 14 about the pivot 13, toward the outdoor side. However, since the roller 14 is engaged with the guide groove 6 of the upper frame 1a, the reaction of the torque causes the shoji 2 to move toward the indoor side by a parallel movement action, but when it moves, the link 12 is The regulating pin 17 comes into contact with a part of the upper stile 1c to regulate the amount by which the shoji 2 moves.

A shoji moving device similar to that described above is provided between the lower stile 2d and the lower stile 1b of the shoji 2, and the roller 14 of the link 12 is connected to the door roller casing 10.
It is pivotally supported between the two wheels of wheel A, and the other structures are similar.

According to the above embodiment, by rotating the handle 4 from the closed state of the shoji shown in FIG. 1, the operating rod 5 moves forward in the direction of the arrow 20, and as shown in FIG. When the end is reached, the guide pin 16 is positioned away from the protrusion 19, and during this time the link 12 remains stationary and the shoji 2 is unlocked. When the operating rod 5 moves further forward, the link 12 is rotated toward the indoor side around the roller 14, as shown in FIG. 7, and the shoji 2 is moved toward the indoor side. Further, by turning the handle 4 in the opposite direction to that described above, the shoji 2 is first housed in the frame 1 from the moved position, and then the shoji 2 is locked.

[Effect of idea]

The sliding shoji moving device based on this invention has an operating rod provided on the frame and a link pivotally supported on the shoji and frame, superimposed in parallel, and the operating pin provided on the operating rod is engaged with the guide hole of the link. In the combined sliding shoji moving device, the guide pin protruding from the link is in contact with the indoor side surface of the convex strip provided on the operating lever, so for example, the engagement relationship with the supporting groove of the operating lever,
Even if the engagement relationship for sliding of each member is formed loosely, such as the engagement relationship of the actuation pin with the guide hole or the engagement relationship of the roller with the link with the frame, the operation pin Since the links are not swayed while the shoji moves through the long hole part of the guide hole to unlock the shoji, the shoji is held immovably and the shoji can be locked and unlocked reliably.
