FIG. 4 is a perspective view of a gate main body mounted on the elevating gate assembly according to the present embodiment.

As shown in the above-described drawings, the elevating gate assembly according to the present embodiment has a mounting plate 10 formed in a rectangular shape, and the mounting plate 10 has a substantially triangular edge member having an arc-shaped side on the upper left (unsigned). ), And a curved member (without reference numeral) having a predetermined interval (separating at a predetermined interval) from the edge member, and a curve draft slot 12 is formed between the edge member and the curve member. . The mounting plate 10 is formed with a mounting portion 102 protruding by press working. The mounting portion 102 has a motor 144, a control portion 142, and a manual / electric switching pin (manual / electric switching means). 146 are provided. Here, the configuration of the drive control means 14 having the manual / electrical switching means 146 and the like is the same as that of a commercially available elevator gate assembly, and a detailed description thereof will be omitted. A winding wheel 22 having teeth 222 is attached to the output end of the drive control means 14, and one rotation shaft 20 is attached to the axis of the winding wheel 22. That is, the winding wheel 22 and the drive control means 14 are provided at one end of the rotating shaft 20. A stopper 26 is provided at a portion of the rotating shaft 20 approaching the winding wheel 22, and a coil spring 24 is provided between the stopper 26 and the winding wheel 22. Further, the other end of the rotating shaft 20 is provided with a mounting plate 10 'corresponding to the portion of the mounting plate 10, a winding wheel 22', a stopper 26 ', and a coil spring 24'. Although omitted in FIG. 1, the mounting plate 10 'is also provided with an edge member and a curve member at positions corresponding to the edge member and the curve member provided on the mounting plate 10, respectively. Therefore, a curve guide slot is also formed.

When the elevator gate assembly according to the present embodiment is actually mounted, as shown in FIG. 2, a horizontal plate 402 and a vertical plate 422 are used at the place where the gate is to be mounted, and The driving structure is attached to the elevating gate installation location by forming a space in which the substantially triangular edge member described in the above can be fitted, and the mounting plate 10 is installed in this space. By adopting such a configuration, when it is desired to replace the elevating gate drive device, it is only necessary to remove it from the space, and this embodiment is more convenient than the conventional one. A guide slot 40 is formed below the horizontal plate 402 near the space and connected to the curve guide slot 12 of the mounting plate 10. A guide slot 42 is formed inside the vertical plate 422.

FIG. 4 shows the shape of the gate main body 30 according to the present embodiment. As shown in FIG. 4, the shape of the gate body 30 according to the present embodiment is such that a plurality of engaging portions 302 that can be engaged with the teeth 222 of each of the winding wheels 22 and 22 ′ are formed. A plurality of abutting members 32 projecting at predetermined intervals are provided at both end edges, and abrupt friction between the edge of the gate body 30 and the wall can be prevented by these abutting members 32. On the surface of the gate main body 30, an elongated blocking member 34 having a function of preventing friction when each part of the gate main body 30 overlaps is provided.

Hereinafter, an operation of the embodiment of the present invention will be described. When raising the gate body 30, the drive control means 14 is driven to rotate the motor 144, thereby rotating the winding wheel 22, and engaging the tooth portion 222 of the winding wheel 22 with the engaging portion 302 of the gate body 30. With this engagement, the gate main body 30 is wound up. When such winding is performed, the coil spring 26 is twisted, and torsion energy is stored. When the gate main body 30 is lowered, the lowering operation of the gate main body 30 is effectively performed using the torsional energy of the coil spring 26 and a predetermined driving force.

[Effect of the invention]

 According to the present invention, the engagement between the teeth of the winding wheel and the engaging portion of the gate body makes it possible to prevent shaking and vibration during winding of the gate body, and abut against the side edges of the gate body. By providing the member, it is possible to reduce the friction between the side edge of the gate body and the wall. In addition, noise can be effectively reduced by providing a blocking member on the gate main body to prevent mutual friction of each part of the gate main body. Furthermore, the installation configuration of the mounting plate of the present invention facilitates the mounting of the elevating gate and the replacement of members.
