[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration control device for a high-speed door rail in a three-door horizontal door such as an elevator.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 5 and 6, a three-door horizontal door such as an elevator is a high-speed door through a hanger 3 with a hanger roller 2 that engages with three parallel stationary high-speed door rails 1. 4 through a hanger 7 with a hanger roller 6 engaging a medium speed door rail 5, and a hanger 11 with a hanger roller 10 engaging a medium speed door 8 with a low speed door rail 9.
Each of the low speed doors 12 is supported via the cord sheave 11, the end of the cord sheave base 13 is attached to the hanger 11, and the large diameter sheave 14 and the small diameter sheave 15 coaxial with each other are provided in parallel at both ends of the cord sheave base 13. An endless roller chain 16 is passed between the large diameter sheaves 14 and 14, and an endless roller chain 17 is passed between the small diameter sheaves 15 and 15. The high speed door 4 and the roller chain 17 are attached to the roller chain 16. The medium speed door 8 is engaged with one side in parallel, and the fixing member 18 such as a hanger case is engaged with the other side, and the speeds of the high speed door, the medium speed door, and the low speed door are
It is designed to open and close at a ratio of 3: 2: 1. The high-speed door rail 1, the medium-speed door rail 5, and the low-speed door rail 9 described above are supported via a fixture 19.

[0003]

With the above construction, the high-speed door rail swings sideways because the support fixtures of the high-speed door rail have a large space (which does not hinder the running of the hanger for medium-speed door rail). For this reason, there has been a problem that the reinforcement or the rail must be thick, and even if the reinforcement or the rail is thick, the lateral runout of the rail cannot be completely stopped.

Therefore, an object of the present invention is to provide a device for stopping the runout of a high-speed door rail without reinforcing or thickening the rail.

[0005]

In order to solve the above-mentioned problems, the present invention proposes three fixed high-speed door rails in parallel,
Supports high-speed doors, medium-speed doors, and low-speed doors through hangers with hanger rollers that engage with medium-speed door rails and low-speed door rails respectively. An endless high-speed traveling body and a low-speed traveling body are provided between both ends of the arranged cord sheave base.Furthermore, the high-speed traveling body is provided with the high-speed door, one side of the low-speed traveling body is a medium-speed door, and the other is the other side. An auxiliary hanger roller provided on the medium-speed door rail on the hanger of the high-speed door and an auxiliary hanger provided on the hanger of the medium-speed door on the high-speed door rail in the three-door horizontal doors that are respectively locked to the fixed fixing members. This is a structure in which hanger rollers are engaged with each other.

[0006]

The auxiliary hanger roller provided on the hanger of the high speed door is engaged with the medium speed door rail, and the auxiliary hanger roller provided on the hanger of the medium speed door is engaged with the high speed door rail.
Stop the swing of the high speed door rail.

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1 and FIG. 2, three parallel high-speed door rails 21, medium-speed door rails 22, and low-speed door rails 23 are provided, and the high-speed door rails 21 are provided with high-speed doors via a hanger 25 with engaging hanger rollers 24. 26, the medium speed door rail 22 is supported by a medium speed door 29 via a hanger 28 with an engaging hanger roller 27, and the low speed door rail 23 is supported by a low speed door 32 via a hanger 31 with an engaging hanger roller 30. I am allowed.

Reference numeral 33 denotes a cord sheave base which is attached to the hanger 31 at its distal end so as to be parallel to the low speed door rail 23. The large diameter sheave 34 is coaxial with the end of the cord sheave base 33 and the tip end in the direction of the high speed door 26. And a small diameter sheave 35 are supported in parallel, and an endless high speed roller chain 36 is provided between the left and right large diameter sheaves 34, 34 and an endless low speed roller chain 36 is provided between the left and right small diameter sheaves 35, 35. A roller chain 37 for use is extended.

The portion of the cord sheave base 33 located below the roller chain 36 in parallel is located on the hanger 25 via the fitting 38, and the middle portion of the roller chain 37 located below parallel is the fitting. Hanger 28 through 39
In addition, the end portion of the cord sheave base 33 parallel to the upper side of the roller chain 37 is fixed by a fixing member 41 via a mounting member 40.
(In the case shown, to the hanger case).

With the above construction, the vanes provided on the car door and the receiving fittings (not shown) provided on the high-speed door are synchronized to open and close. With the opening and closing, the speed of the high speed door 26, the medium speed door 29, and the low speed door 32 becomes a ratio of 3: 2: 1.

Further, the medium speed door rail 22 has an auxiliary hanger roller 42 provided on the hanger 25 of the high speed door 26.
However, the high-speed door rail 21 has a hanger 2 for the medium-speed door 29.
Auxiliary hanger rollers 43 provided in No. 8 are engaged with each other.

With the above construction, the lateral swing of the high speed door rail is stopped by the auxiliary hanger roller 42 engaged with the medium speed door rail 22 and the auxiliary hanger roller 43 engaged with the high speed door rail 21.

Reference numeral 44 in the figure denotes a fixture for the high speed door rail 21, the medium speed door rail 22, and the low speed door rail 23.

[0014]

As described above, according to the three-door horizontal door according to the present invention, the auxiliary hanger roller provided on the medium speed door rail on the high speed door hanger and the auxiliary hanger roller provided on the high speed door rail on the medium speed door hanger. Since the hanger rollers are engaged with each other to prevent the lateral vibration of the high-speed door rail, it is possible to eliminate the inconvenience of having to reinforce or thicken the rail.
