And a wheel frame 4 rotatably supported by a shaft 42 so as to be rotatable about a wheel 41 having a bulged portion 41a formed in the center, which is fitted into the groove 1a of the Kamoi rail 1 and is prevented from coming off. Have been.

The wheel frame 4 is provided on the side plate 3 of the main body case 3.
2 and 32 are pivotally supported by a shaft 34 so as to be able to swing up and down, and are guided in the main body case 3 by the shaft 34 so as to be movable in the width direction.

Numeral 5 is an adjusting screw for moving the wheel frame 4 in the width direction in the main body case 3, and a front plate 31 of the main body case 3
Is inserted through a horizontal elongated hole 31a formed above
It is screwed into the screw hole 61 of the adjusting member 6 having the engaging portion 6a engaged with a part of the wheel frame 4 on the pivot portion side, and is fixed at that position by tightening the adjusting screw 5. The pin 6b implanted in the adjusting member 6 is fitted into a horizontally elongated hole 31d formed in the front plate 31, so that the adjusting member 6 can smoothly slide left and right.

Reference numeral 7 denotes a spring which constantly urges the wheel frame 4 upward to press the wheel 41 against the Kamoi rail 1, and has one end separated from a pivot portion of the wheel frame 4. The other end is suspended on a part of a nut that moves in the front-rear direction by an adjustment screw described later.

Reference numeral 10 denotes a mounting screw for the door lock 2 for the gate.

Next, the specific usage of the device of the present invention will be described.

First, the door door 2 is fitted into a predetermined recess formed in the upper end of the sliding door A, and the mounting screw 10 is inserted through the round hole 31c of the front plate 31 of the main body case. The sliding door A is fixedly fastened to a part of the sliding door A, and the center bulging portion 41a of the wheel 41 of the sliding door 2 of the sliding door A is erected so as to fit into the groove 11 of the Kamoi rail 1. Looking at the degree of inclination of A, if it is inclined, the inclination of sliding door A is corrected by the method described later.

When correcting the inclination of the sliding door A, the wheel 41 is loosened once with a screwdriver because the central bulge 41a is fitted into the groove 11 of the duck rail 1 and its position does not change. To make the wheel frame 4 free in the left-right direction in the main body case 2, push the sliding door A to the vertical state, and when the sliding door A is considered to be in the vertical state, screw the adjusting screw 5 again with the screwdriver Then, the sliding door A is erected vertically.

When the sliding door A is opened and closed, the wheel 41 of the door lock 2 rolls while the central bulging portion 41a is fitted in the groove 11 of the Kamoi rail 1, so that the lateral pressure is applied to the sliding door A. It does not come off even if it hangs.

Since the wheel 41 always tries to protrude to the maximum by the restoring force of the spring 7 for urging the wheel frame 4, unless the gap between the Kamoi rail 1 and the wheel 41 is too large. At the contact surface with the Kamoi rail 1, the wheel 41 is pressed against the Kamoi rail 1 by the restoring force of the spring 7.

The fact that the wheel 41 is pressed against the Kamoi rail 1 means that the rolling of the wheel 41 is braked. It is possible to adjust the sliding degree of the sliding door A, that is, excessive sliding, and that the opening / closing becomes too heavy.

When the sliding door A slides too much, when the adjusting screw 8 is rotated in the right direction, that is, in the direction in which the restoring force of the spring 7 is increased, the adjusting screw 8 can rotate but cannot move in the front-rear direction. Therefore, only the nut 7 screwed to the adjusting screw 8 moves backward, the spring 7 is compressed, the force for pushing the wheel frame 4 upward increases, and the pressing force of the wheel 41 against the Kamoi rail 1 increases. In addition, it can be adjusted to the optimum sliding condition.

When the opening and closing of the sliding door is too heavy, the adjusting screw 6 may be rotated in the opposite direction, that is, in the direction in which the restoring force of the spring 7 becomes weaker.

[0028]

As described above, according to the guide apparatus for a sliding door according to the present invention, the dumbbell rail attached to the dumbbell and the wheel fitted into the groove of the dumbbell rail and prevented from coming off are provided. A door frame for a gate that pivotally supports a rotatably supported wheel frame in a main body case so as to be swingable in a vertical direction. The wheels are operated by operating an adjusting screw inserted from a front plate of the main body case. Since the frame can be moved in the width direction in the main body case, when the sliding door is erected, the wheel can be easily erected simply by pushing the wheel into the main body case once. Even when the door is open, the Kamoi Rail fits inside the Kamoi and is better in appearance than the one in which the Kamoi Rail hangs down as in the prior art.

Further, a spring is provided in the main body case to constantly urge the wheel frame upward, and the spring can change the compression force by rotating an adjusting screw inserted from the front plate of the main body case. Therefore, by operating the adjusting screw, the pressing force of the wheel against the Kamoi rail can be varied, and the sliding degree of the sliding door can be adjusted to an optimum state.

Further, since the door can be used simply by attaching the door door to the left and right upper ends of the sliding door, it is not necessary to form a groove in the upper end of the sliding door over the entire length in the longitudinal direction, and the sliding door is not weakened in strength. Even if the sliding door is made of metal as well as wood, it can be easily installed, and even if the sliding door shrinks or warps due to the aging effect and the distance from the upper end of the sliding door to the threshold changes, the wheel frame automatically moves. In order to respond by swinging, the sliding door never comes off.

In addition, a plurality of vertical rack teeth are formed on the inner surface of the front plate of the case body, and the adjusting member is provided at a portion of the adjusting member facing the inner surface of the front plate of the slider body case. By forming a plurality of rack-tooth-shaped concave grooves that mesh with the ridges of the front plate, the tightening and fixing of the adjusting member, that is, the adjusting screw of the wheel frame, is ensured. It is possible to expect a more stable use state without deviation.
