The present invention relates to an elevator door rail device, and in particular, a door that is opened and closed when a passenger gets on and off a cage of an elevator is suspended so that the shape of the door rail to be guided and changed can be improved and the coupling structure with the pocket can be easily and accurately mounted. An elevator door rail device is provided.

In general, as shown in FIG. 1, a steel plate hanger in which a steel plate door rail 2 is mounted to a fixing bolt 3 and is fixed to an upper end of a door 4 in a package 1 properly bent into a steel plate as shown in FIG. At both ends of the plate 5 a roller 6 is fitted with a shaft 6 'which allows the door 4 to hang smoothly on the door rail 2 and under the door 4 the door 4 The seal 7 is installed so that the movement moves without shaking or change of position.

FIG. 2 is a cross-sectional view showing a conventional elevator door rail device, and FIG. 3 is a perspective view showing a conventional door rail device having several fixing holes 1a at positions corresponding to each other of the pocket 1 and the door rail 2. Perforations 2a are respectively formed, and a collar inserter 2b is formed around the fixing hole 2a of the door rail 2 so that one end of the colter 8 for the gap oil is inserted into the insertion seat 2b. It was located in the door rail 2 and the pocket 1, and it fastened with the bolt 3 and the nut 9 which have a head part.

10 is a derailment prevention roller mounted on the hanger plate 5 and in contact with the lower end of the door rail 2, and the derailment prevention roller 10 may be subjected to an external load on any part of the door 4 by external force. Hanger rollers (6) to prevent derailment.

In the conventional door rail device, the door 4 is opened and closed in an arrow direction by a separate driving device.

However, such a conventional door rail device has a curved surface 2c, a bolt fixing hole 2a, a collar inserter 2b and a bolt head insertion seat 2b having an appropriate radius formed at the upper and lower edges of the door rail 2; ') Should be formed by difficult machining, and the head of the fixing bolt 3 should be machined to prevent the interference between the fixing bolt 3 and the hanger plate 5, so that the productivity is not only reduced, but also the focus (1). ) And the fixing holes (1a) and (2a) of the door rail (2) must match, but there was a problem in assembling due to the processing of rice paddles, and the space keeping caller (8) between the door rail (2) and the pocket (1) ) Is interposed and is fastened by the bolt 3 of the long length, the bolt 3, the collar 8 and the package 1 bends due to the load of the door 4, the door ( 4) is out of position and interferes with surrounding structures, so opening and closing is not smooth. It could point to a problem.

The present invention has been devised to solve such a conventional coupling, the door rail of a unique shape extruded by hard alloy or metal material can be simply assembled to the kit using only bolts and nuts, so that it can be used without deformation. When described in detail by the accompanying drawings as follows.

As shown in FIG. 4 and FIG. 5, the door rail 22 is fixed to the pocket 21 fixed to the cage of an elevator, and the door rail 22 is attached to the hanger plate 24 fixed to the door 23. As shown in FIG. In the door rail device fixed to the hanger roller 25 and the derailment prevention roller 26 fixed to the guide movement in the), the door rail 22 is extrusion molded into a metal material such as hard alloy aluminum, door rail (22) On one side of the body, protrusions 22b and 22b 'each having curved portions 22a and 22a' contacting the hanger roller 25 and the derailment prevention roller 26 at the upper and lower edge portions protrude upward and downward, and An interval holding portion 22c for maintaining the gap between the pocket 21 and the rollers 25 and 26 is integrally formed inside, and the head of the fixing bolt 27 is formed in the middle of the gap holding portion 22c. T-shaped fixing groove 22d into which the 27a is inserted is formed in the longitudinal direction, and the inner end of the body of the door rail 22 is a pokey. The contact surfaces 22e and 22e 'contacting the 21 are extruded to be formed on the same plane on both sides of the fixing groove 22d, so that the head portion 27a is formed in the fixing groove 22d of the door rail 22. ) Is inserted into a plurality of fixing holes (21a) formed in the pocket 21 to the fixing bolt 27 is fastened with a nut (28).

When the door rail 22 is fixed to the pocket 21, the present invention has thus been provided several fixing bolts 27 in the T-shaped fixing groove 22d formed in the gap holding part 22c of the door rail 22. Insert the head portion 27a of each of the fixing bolts 27 into the fixing holes 21a formed at regular intervals in the pockets 21, and fasten the nuts 28 respectively to the door rails 22. After fixing the hanger plate 25 mounted on the hanger plate 24 of the door 23 is suspended on the door rail 22 to guide the movement.

In the door rail device of the present invention, the curved portions 22a and 22a 'contacting the rollers 25 and 26 are formed integrally on both side protrusions 22b and 22b' of the door rail 22. The kit 21 and the gap holding portion 22c for maintaining the gap between the rollers 25 and 26 and the fixing groove 22d into which the head 27a of the fixing bolt 27 is inserted are integrally formed. As such, each element portion, that is, a fixing hole (1a) (2a) for fixing the door rail (2) to the pocket (1), the insertion of the head of the collar 8 and the fixing bolt (2) is inserted as in the prior art It is not necessary to form the seats 2b, 2b 'and the curved surfaces 2c on which the rollers 5 and 10 are in contact with each other by machining, and also does not use a separate caller 8 during assembly. It can be assembled, fit the fixing hole (21a) of the pocket 21 while inserting the head (27a) of the several fixing bolts 27 in the fixing groove (22d) of the door rail (22) while moving left and right freely Can be fastened Because the defects that are cumbersome fastening of the bolt (3) is eliminated if the position is not exact fit of the fixing hole (1a), (2a) as in the prior art.

In addition, since the contact surfaces 22e and 22e 'are formed in the longitudinal direction at the inner end of the door rail 22 to be firmly fixed to the package 21, the door 23 is assembled in the state in which the door 23 is assembled. Even if a load of the load is applied to the door rail 22 by the hanger roller 25, the warp does not occur in the door rail 22 and the pocket 21.

The door rail device of the present invention as described above is formed by extruding the door rail with a metal material so that each element is integrally formed, and thus the manufacturing cost is reduced compared to the steel door rail manufactured by a complicated machining as in the prior art. In addition, the fastening operation is simplified because the fastening work of the pocket is changed while changing the position of the fixing bolt where the head is inserted into the fixing groove without using a caller, and the door rail and the pocket by the load of the door after the door is assembled. Since the deformation of the back is eliminated, there is an advantage that the door opening and closing is performed smoothly.
