Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing door device with adjustable hanging height, which is an improvement of a hanging type opening/closing door.

Conventionally, when assembling a suspended type door such as an automatic opening/closing door, if an appropriate gap could not be obtained between the opening/closing door, the earth rail, and the lower rail during assembly, the upper rail The fix was to raise the position of the blind mounting member and change the mounting height of the upper rail.

Therefore, it took a long time to make corrections, resulting in a significant loss of time for assembling the opening/closing door device, etc.

The present invention has been made in view of the above-mentioned points, and its purpose is to improve assembly work even when an appropriate gap cannot be obtained between the opening/closing door and the upper and lower rails. To provide an opening/closing door device with a hanging height adjustment that can be easily modified by modifying a door roller and a part of a hanger, does not require a high level of construction accuracy in assembly construction, and can significantly shorten assembly construction time. .

Therefore, in the present invention, a hanger 2 is provided on the upper part of the opening/closing door 1 so as to protrude upward, a shaft support hole 17 is provided at one end of the hanger 2 that opens on the inner and outer surfaces of the hanger 2, and the hanger 2 is provided at a certain distance from the shaft support hole 17. An arcuate long swinging hole 18 is opened in the inner and outer surfaces of the hanger 2 and is elongated in the vertical direction and has the shaft support hole 17 as the center of its radius. 17
The door roller mounting plate 3 is pivoted to the hanger 2 with a mounting screw 10 passed through the swing hole 18, and the other end of the door roller mounting plate 3 is fastened to the hanger 2 with a mounting screw 10 passed through the swinging slot 18, and runs on the upper rail 7. The above object has been achieved by an opening/closing door device with hanging height adjustment, which is characterized in that the door roller 5 is pivotally attached to the door roller mounting plate 3 between the mounting screws 10 and 10 at both ends. will be explained in detail with examples.

A pair of L-shaped hangers 2, 2 are attached to the upper end of the opening/closing door 1 at a constant interval, and a shaft support hole 17° 17 is provided at one end of the vertical piece 2A, 2A of each hanger 2, 2. In addition, a swinging elongated hole 18, 18 is bored downward at a certain distance from the shaft support holes 17, 17.

The swinging elongated hole 18° 18 has a circular arc shape with a constant radius centered around the shaft support holes 17, 17, and one end of the door roller mounting plates 3, 3 is pivotally supported with a mounting screw 10.10, respectively. The other ends of the door roller mounting plates 3, 3 are fixedly fixed to the arcuate swinging slots 18.18 with mounting screws 10.10, as shown in FIG. 3, so as to be able to swing freely.

Door wheels 5, 5 are rotatably inserted into door wheel shafts 4, 4 which are horizontally attached to the door wheel mounting plates 3, 3.

Steady rests 6, 6 are placed at a certain interval on the lower end of the opening/closing door 1.
protrudes downward.

As shown in Figs. 1 and 2, the opening/closing door 1 has door wheels 5, 5 suspended from a plain-like earthen rail 7 in a freely movable manner, and steady rests 6, 6 are slid onto the lower rail 8. It is attached so that it can move freely to prevent the opening/closing door 1 from swinging.

The door rollers 5, 5 have a recessed portion 5A in the center of their circumferential surfaces, as shown in FIG. 4, and are fitted and locked onto the soil rail 7.

The silent earth rail 7 is horizontally attached to a blind mounting member 11, and a motor 14 such as a pulley driven by a motor 12 and a reduction gear 13 is disposed at one end of the upper rail 7. A driven wheel 15 like a pulley is disposed at the other end of the upper rail 7, and a ft belt 16 such as an endless V-belt is rotated on the motive wheel 14 and the driven wheel 15 as shown in FIG. It can be hung freely.

The hangers 2, 2 are connected to a part of the belt 16, and the motive wheel 14 is driven via the motor 12 and the speed reducer 13 to rotate the belt 16, so that the opening/closing door 1 can be freely run on the upper rail 7. , the opening/closing door 1 can be automatically opened and closed via the electric control device 19.

However, when the opening/closing door 1 is suspended between the lower rail 8 and the upper rail 7 so as to be freely movable, the gap between the opening/closing door 1 and the lower rail 8 and the upper rail 7 is large and inappropriate.
Also, when the clearance between the opening/closing door 1, the lower rail 8, and the upper rail 7 is small and not appropriate, the opening/closing door 1, the lower rail 6,
To adjust the height between the upper rails 7, use the long swing holes 18.
Loosen the mounting screw 10.10 on the 18 side and move it upward to raise the door rollers 5, 5 as shown in position a in Fig. 5, and move them downward as shown in position b in Fig. 6. 5.5 is lowered so that the hanging height of the opening/closing door 1 can be adjusted.

Here, by making the door wheel mounting plates 3, 3 lever-shaped, the weight of the opening/closing door 1 can be easily operated using the lever principle, and the door axles 4, 4 are pivoted to the center portions of the door wheel mounting plates 3, 3, respectively. This allows the height of the door wheels 5, 5 to be proportionally reduced and adjusted accurately.

As described above, in the present invention, a shaft support hole that opens on the inner and outer surfaces of the hanger is provided at one end of the hanger, and the shaft support hole is spaced apart from the shaft support hole by a certain distance and is elongated in the vertical direction. A long arc-shaped swinging hole is opened on the inner and outer surfaces of the hanger, and one end of the door roller mounting plate is pivoted to the hanger with a mounting screw passed through the pivot hole, and the other end of the door roller mounting plate is Since the end is fastened to the hanger with a mounting screw that passes through the long swinging hole, the other end of the door roller mounting plate can be adjusted up and down along the swinging long hole with one end as the center. The height of the door roller attached to the door roller mounting plate can be adjusted arbitrarily, and the mounting screws that connect the door roller mounting plate to the hanger are horizontally inserted into the shaft support holes and swing holes that open on the inner and outer surfaces of the hanger. It is inserted and screwed into the door roller mounting body, and the weight of the opening/closing door does not hang in the direction perpendicular to the axial direction of the mounting screw. There is no fear that the screw threads of the mounting screws will be damaged and the hanging height of the door roller will become impossible to adjust if the weight is applied in the axial direction of the mounting screws.

In addition, the weight of the door is applied to the door roller mounting plate via the door roller, but in the present invention, one end of the door roller mounting plate is pivoted to the hanger with a mounting screw passed through the pivot hole, and the door roller is pivoted to the hanger. The other end of the mounting plate is fastened to the hanger with a mounting screw passed through the swinging slot, and the door roller mounting plate is pivoted up and down along the swinging slot around the shaft support hole. Since the height of the door roller attached to the door roller mounting plate is adjusted between the mounting screws at both ends, the door roller mounting plate can be moved using the principle of leverage and can be adjusted by swinging up and down. The door roller mounting plate can be moved with a small force even when the weight of the door is applied, making it easy to adjust the door roller mounting plate.Moreover, the weight of the door is divided and supported by a pair of mounting screws at both ends of the door roller mounting plate. As a result, the door roller mounting plate can be reliably fixed to the hanger without a large weight of the door being applied to the mounting screws passed through the long swinging holes of the hanger.
