Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding door horizontal adjustment and holding device, and in particular, to a sliding door lifting shaft protruding downward from a hanging wheel frame, and to a right vertical stile of a sliding door inserted into the sliding door lifting shaft. Provided guide bearings, sliding door lifting fittings, sliding door horizontal adjustment fittings, thrust bearings, tightening nuts,
The present invention relates to a sliding door horizontal adjustment and holding device which is formed from an adjustment bolt and an adjustment nut, and which supports a sliding door in a freely pivotable manner while fully adjusting and maintaining the horizontal level of the sliding door.

Conventionally, the first door with a turning mechanism, especially in automatic doors, is
As shown in Figures (a) and (b), the upper surface of the sliding door 3 and the locking piece 2 protruding from one end A of the side wall of the hanging wheel frame 1 that moves linearly from side to side using the power of the drive unit. By locking with the locking hole 4 protruding from A of C, the sliding door 6 moves left and right while the sliding door 6 is lifted up, and the sliding door 6 is held in the front direction of the sliding door 6. By pulling the casing, the locking piece 2 and the locking hole 4 are unlatched, and the upper shaft 5A, which is provided upwardly protruding from the other end B of the upper surface part C of the sliding door 6, and the side wall of the hanging wheel frame part 1 are released. The other end B of the lower surface part of the sliding door support part 5 and the sliding door support part 5 consisting of a shaft support part 5B which is protruded from the other iiB and rotatably supports the upper shaft 5Ak
Using the sliding door steady rest part 6 as a fulcrum, it consists of a lower shaft 6A protruding downward from the lower shaft 6A and a shaft rotating part 6B that is suspended from the lower shaft 6A and contacts the inner wall of the lower rail 7 to rotate the lower shaft 6At. There is one in which the sliding door 6 rotates.

In this technique, the sliding door 6 is suspended and supported from the hanging wheel frame 1 by the locking pieces 2 and the locking holes 4 and by the sliding door support portion 5. In other words, when the sliding door 6 moves in a straight line, the hanging wheel frame 1 supports the sliding door 6t by lifting it at two points, the locking piece 2 and the sliding door support part 5, but when the sliding door 3 rotates and engages with the locking piece 2. When the locking with the stop hole 4 is released, the hanging wheel frame 1 suspends and supports the sliding door 6 at one point of the sliding door support section 5. The sliding door steady stop part 6 is used to prevent the shaft rotating part 6B from coming into contact with the inner wall of the lower rail 7 and causing the sliding door 6 to move sideways when the sliding door 6 moves on the @ line, and to prevent the sliding door 6 from moving sideways when the sliding door 6 turns. Rotating part 6
Since B contacts the inner wall of the lower rail 7 and rotates the lower shaft 6A', it can serve as a support point for the sliding door 6. Therefore, the sliding door 6 is cantilevered with the sliding door support part 5 as a fulcrum. The structure is baυ. Since the sliding door support part 5 suspends and supports the sliding door 3 and also rotates the sliding door 3, in order to rotate the sliding door 6, it is natural to drill an elliptical hole in the shaft support 5B and between the upper shaft 5A. Although a gap is required, as mentioned above, since the sliding door 6 has a cantilevered structure, this prior art requires only this gap valve to cover 1 m of the sliding door 6 due to its own weight.
A: There is a problem that the door edge lowers. In this case, since the sliding door support part 5 does not have a mechanism to adjust the horizontal level of the sliding door B, the door tip cannot be raised, and therefore, if the sliding door tip has a steep descent, when the sliding door B is turned back to its original position. There may also be cases where the lower end of the sliding door 6 hits the lower rail 7.

Further, there is also the inconvenience that the sliding door 6 must be lifted in order to lock the locking piece 2 and the locking hole 4 together. Furthermore, there is a problem in that the sliding door support part 5 becomes fatigued due to repeated stress over many years, causing damage.

This invention was made by focusing on the problems of the prior art, and includes a sliding door lifting shaft that projects downward from the hanging wheel frame, and a sliding door right 911JM1 stile that is inserted into the sliding door lifting shaft.
