Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door provided with a vertical adjusting mechanism and a horizontal adjusting mechanism for a sliding door.

[0002]

2. Description of the Related Art As this kind of door roller, a door roller shown in FIG. 6 is commercially available, and wheels 40 are supported on an inner frame 41 via a shaft 42 so as to freely rotate. The inner frame 41 can swing up and down around a support shaft 44 fixed to the case 43.
You can slide left and right along the axis of. The vertical adjustment mechanism includes a screw shaft 45 rotatably supported by a case 43 and a screw shaft 4.
5 is displaced along the screw shaft 45, whereby the inner frame 41 can be tilted around the support shaft 44 to be adjusted up and down.

The right and left adjusting mechanism includes an adjusting shaft 48 provided with an eccentric pin 47, a slide block 49 which is slid left and right by the eccentric pin 47, and a rotating engagement with the adjusting shaft 48 to perform a joint engagement at a constant rotation angle. And a click ring 50. The slide block 49 has a groove 51 that engages with the eccentric pin 47. By rotating the adjustment shaft 48,
The slide block 49 is relatively moved to the left or right relative to the case 43 by that amount, and the inner frame 41 can be slid along the support shaft 44 to adjust the left and right.

[0004]

In the above-mentioned door roller, the screw shaft 45 and the adjusting shaft 48 can be easily rotated in a single state. However, when the sliding door panel is built in the door frame, the door weight acts on the inner frame 41 and the wheels 40,
A large force is required to rotate the adjustment shaft 48 with a driver, and it is difficult to perform left-right adjustment. This is because the rotational operation radius when the adjustment shaft 48 is rotated by a driver and the eccentric pin 4
This is because there is no large difference in the operation radius when the slide block 7 slides the slide block 49, and a sufficient boosting effect cannot be obtained. In this regard, in the case of an up-down adjustment mechanism using the screw shaft 45 and the plate nut 46 as adjustment elements, the screw itself exerts a boosting action. Can be rotated without any trouble. For the above reason, when performing the left-right adjustment, one side of the sliding door panel is lifted, and the adjustment shaft 48 is rotated while the door weight acting on the door roller is released, so that the adjustment operation is troublesome.

The eccentric pin 47 is slidably moved at a maximum of 90 degrees before and after the center neutral position to slide the slide block 49. For this reason, a difference occurs in the lateral movement component of the eccentric pin 47 when the adjustment shaft 48 is rotated by a certain angle due to the difference in the rotation position of the adjustment shaft 48. That is, a large lateral movement component is obtained in the vicinity of the neutral position, but the lateral movement component becomes smaller as the distance from the neutral position increases. In addition, the fine adjustment is difficult because the slide block 49 is displaced by the maximum adjustment amount only by rotating the eccentric pin 47 for a quarter of a turn, and the left and right adjustment is performed while the operation of the adjustment shaft 48 and the confirmation of the adjustment result are alternately performed. Considering that it is necessary to perform the adjustment work and the adjustment work must be performed with the sliding door panel being lifted as described above, the left and right adjustment is difficult as a whole, and the adjustment work requires extra labor.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sliding door door that can easily adjust the position of the sliding door even when the weight of the sliding door panel is acting on the sliding door. Another object of the present invention is to allow the adjustment result to be proportional to the operation amount of the adjustment tool, and to make the adjustment amount per unit operation amount of the adjustment tool small, to easily perform minute adjustment, and as a whole of the sliding door panel, An object of the present invention is to provide a door pulley that can easily and quickly perform a left-right adjustment operation.

[0007]

According to the door roller of the present invention, a wheel 4 and a wheel 4 are supported inside a case 3 so as to freely rotate.

The left / right adjustment mechanism includes an outer frame 10 slidably supported by a guide shaft 15 fixed to the case 3, a lateral adjustment screw 12 rotatably supported by the case 3, and an operation plate that is operated back and forth by the lateral adjustment screw 12. 13
And a cam mechanism that is provided between the outer frame 10 and the operation plate 13 and converts a front-rear operation of the operation plate 13 into a left-right operation of the outer frame 10.

The above-mentioned vertical adjustment mechanism is supported by a guide shaft 15 so as to be slidable back and forth and horizontally slidably, and is supported by a case 3 so as to be freely rotatable and horizontally slidable. Vertical adjustment screw 21
And a vertical guide groove 14 of an outer frame 10 for guiding the axle 4a of the wheel 4 so as to be slidable up and down.
a and the inclined groove 22 of the inner frame 20 that is displaced vertically.

More specifically, a chamber 5 which opens downward in the case 3 is provided, and a pair of upper and lower guide shafts 15 traversing the chamber 5 to slide the left and right walls of the outer frame 10 having a U-shaped cross section. To support. The cam mechanism includes a pin 11 fixed to the upper wall of the outer frame 10 and a horizontal cam groove 17 formed of a linear inclined groove provided on the operation plate 13. The lateral guide groove 16 provided on the inner wall of the chamber 5 guides and supports the pin 11 slidably to the left and right. The horizontal adjustment screw 12 screwed with the screw portion 18 provided at one end of the operation plate 13 is disposed between the upper wall of the outer frame 10 and the inner frame 20.

[0010]

The horizontal position of the wheel 4 is adjusted by rotating the lateral adjustment screw 12. By rotating the horizontal adjustment screw 12,
As shown in FIG. 5, the operation plate 13 moves forward or backward. The front-back operation of the operation plate 13 is converted into a left-right operation by a cam mechanism, and the left-right position of the wheels 4 can be changed by moving the outer frame 10 to the left or right. As described above, when the outer frame 10 is operated left and right via the lateral adjustment screw 12 and the operation plate 13, the rotational force applied to the lateral adjustment screw 12 can be amplified and transmitted to the outer frame 10. Even in the state of acting on the door wheel, the left and right trouble of the wheels 4 can be performed without any trouble.

The vertical position of the axle 4 is adjusted by a vertical adjusting screw 21.
Is performed by rotating. When the vertical adjustment screw 21 is rotated, the inner frame 20 moves forward or backward as shown in FIG. 4, and the front and rear positions of the inclined grooves 22 provided in the inner frame 20 change.
The axle 4a of the wheel 4 is provided with a vertical guide groove 14 provided in the outer frame 10.
, The wheel 4 does not move along with the inner frame 20, but moves either up or down by the displacement of the inclined groove 22. Similarly to the horizontal adjustment mechanism, the vertical adjustment mechanism can amplify the rotational force applied to the vertical adjustment screw 21 and transmit it to the wheels 4. The inner frame 20, the vertical adjustment screw 21, and the wheels 4 move right and left along with the left and right movement of the outer frame 10.

The cam mechanism comprises a lateral cam groove 17 and a pin 11 which are relatively moved. When the lateral cam groove 17 is formed as a linear inclined groove, the outer frame 10 can be displaced in proportion to the operation amount of the operation plate 13. Moreover, in order to move the outer frame 10 from the center of the case 3 to the left and right maximum adjustment positions, it is necessary to rotate the horizontal adjustment screw 12 many times.
The outer frame 10 can be moved little by little. Therefore, when the adjustment amount per one rotation of the lateral adjustment screw 12 is fixed and the amount of left / right adjustment of the door wheel is to be estimated, the rotational adjustment of the lateral adjustment screw 12 can be performed by that amount, and the position adjustment can be surely performed. I can do it. Fine adjustment can be easily performed.
