Description

[Detailed explanation of the idea] This invention relates to improvements to elevator doors.

First, a conventional elevator door will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is an entrance, and 2 is a sill forming the lower edge of the entrance 1, which is provided with a guide groove 2a.

Reference numeral 3 denotes the main body of the sliding door whose upper portion is appropriately suspended to open and close the entrance/exit 1, and 3a is a front plate made of a thin steel plate, both ends of which are formed in the shape of a groove.

Reference numeral 3b indicates a reinforcement fixed to the lower end of the top plate 3a, and 4 is a guide piece for the door. A sliding member 4b made of synthetic resin such as nylon is fixed to the lower end of a core metal 4a made of steel plate, and the upper end is fixed to the lower end. It is fixed to the reinforcement 3b with fasteners 5 made of bolts.

That is, when the door is opened and closed, noise and vibration are generated due to sliding and collision between the guide groove 2a and the sliding member 4b, and this is transmitted from the metal parts of the core bar 4a and reinforcement 3b to the top plate 3a, causing the top plate 3a to become larger. There was a problem that caused the aircraft to vibrate, creating harsh noise for passengers.

This invention is intended to solve the above-mentioned drawbacks and to provide an elevator door guiding device that allows quiet door opening/closing operations.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

In the figure, the same reference numerals as in FIGS. 1 and 2 indicate the same parts, and 4C is an elongated hole in the vertical direction provided in the core bar 4a, the width of which is one size larger than the diameter of the fastener 5.

6.7 is an elastic body made of a non-metallic elastic material such as rubber, and has protrusions 6 a and 7 a on the negative side that fit into the elongated hole 4C, and an insertion hole for the fastener 5 in the center thereof. 6b.

7b is provided.

A metal seat plate 8 prevents local compression of the elastic seat 6.7 by the fastener 5, and is provided with an insertion hole 8a for the fastener 5.

That is, since the guide piece 4 is attached to the main body 1 as shown in FIG. 3, it is completely elastically supported by the main body 1.

Therefore, all the noise and vibrations generated between the guide groove 2a and the sliding member 4b are absorbed and blocked by the elastic body 6°7 and are not transmitted to the top plate 3a.

Therefore, quiet opening and closing operations can be achieved without causing the top plate 3a to vibrate.

In addition, since the core bar 4a is provided with a long hole 4C in the vertical direction, if the elastic bodies 6 and 7 are melted due to a fire, the core bar 4a will move downward within the range of the long hole 4C, and the alignment dimension with the guide groove 2a will be reduced. Since this increases, there is no risk that the main body 1 will be thermally deformed and its lower end will no longer be held.

As explained above, this invention prevents noise and vibration generated between the guide groove and the sliding member from being transmitted to the door by interposing elastic bodies between the door body and the guide piece, and between the guide piece and the fastener. This allows for quiet door opening and closing operations.
