Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is suitable for shaking high-speed door rails in three-panel horizontal sliding doors such as elevators. This relates to a locking device.

0002

[Conventional technology]

Conventionally, three-panel horizontal sliding doors for elevators, etc. have three-panel horizontal sliding doors, as shown in Figures 5 and 6. Through a hanger 3 with a hanger roller 2 that engages the fixed high-speed door rail 1 where books are arranged in parallel, The high-speed door 4 is moved through a hanger 7 with a hanger roller 6 that engages with the medium-speed door rail 5. A hanger 11 with a hanger roller 10 that engages the medium speed door 8 with the low speed door rail 9. The cord sheave base is attached to the hanger 11. Attach the end side of the cord sheave base 13, and also attach a coaxial large diameter shaft to both ends of the cord sheave base 13. The sheave 14 and the small diameter sheave 15 are provided in parallel, and the large diameter sheave 14 and 14 are endless. An endless roller chain 17 is inserted between the small-diameter sheaves 15 and 15. The high-speed door 4 is connected to the roller chain 16, and the roller chain 17 is connected to the roller chain 16. On one parallel side, there is a medium speed door 8, and on the other side there is a fixed part such as a hanger case. material 18 is engaged, and the speed of the high speed door, medium speed door, and low speed door is set to 3:2: It is designed to open and close at a rate of 1. In addition, the above-mentioned high-speed door rail 1, medium-speed door rail 5, and low-speed door rail 9 are It is supported via a fixture 19.

0003

[Problem that the idea aims to solve]

When configured as above, the high-speed door rail support fixtures have large (medium) spacing. (does not obstruct the running of the hanger for the high-speed door rail), so the high-speed door rail can swing sideways. . For this reason, it is necessary to increase the thickness of the reinforcement or rail, and also to increase the thickness of the reinforcement or rail. The problem is that even if the rail thickness is increased, it is not possible to completely stop the rail from swinging sideways. there were.

0004 Therefore, the challenge of this idea was to create a high-speed door without reinforcing or increasing the thickness of the rail. It is an object of the present invention to provide a device designed to stop the swinging of a rail.

[0005]

[Means to solve the problem]

In order to solve the above problems, this invention consists of three parallel fixed high-speed door rails. , hanger with hanger rollers that engage with medium-speed door rail and low-speed door rail, respectively. Supports high speed door, medium speed door, low speed door through, and also on the hanger of said low speed door Cord sheave base supported at the end and placed parallel to the low-speed door rail An endless high-speed running body and a low-speed running body are provided between both ends of the The above-mentioned high-speed door is attached to the medium-speed door on one parallel side of the low-speed traveling body, and the other side is fixed in place. In the case of a three-panel horizontal sliding door that is respectively fixed to a fixed member, the above-mentioned Place the auxiliary hanger roller provided on the hanger of the high-speed door onto the high-speed door rail. Adopts a configuration in which the auxiliary hanger rollers provided on the hanger of the medium-speed door are engaged with each other. This is what I did.

[0006]

[Effect]

The auxiliary hanger roller installed on the hanger of a high-speed door can be used as a medium-speed door rail. Engage the auxiliary hanger rollers provided on the hanger in A with the high-speed door rails, respectively. Stops swinging of high-speed door rails.

[0007]

【Example】

Embodiments of this invention will be described below with reference to the accompanying drawings. As shown in Figures 1 and 2, three parallel high-speed door rails 21, medium-speed door rails 21, A high speed door rail 22 and a low speed door rail 23 are provided, and the high speed door rail 21 is provided with an engaging door rail 22 and a low speed door rail 23. The high-speed door 26 is connected to the medium-speed door rail 2 via a hanger 25 with a hanger roller 24. 2, a medium-speed door 29 is connected to a low-speed door via a hanger 28 with a hanger roller 27 that engages A low-speed door is attached to the door rail 23 via a hanger 31 with a hanger roller 30 that engages with the door rail 23. 32 are supported respectively.

[0008] 33 is attached to the end side of the hanger 31 and placed parallel to the low speed door rail 23 With the code sheave base 33, the end of the code sheave base 33 and the high speed door 26 A large-diameter sheave 34 and a small-diameter sheave 35 coaxial with each other are arranged parallel to each other. In addition, an endless high-speed roller chain is installed between the left and right large-diameter sheaves 34, 34. An endless low-speed roller chain 3 is installed between the left and right small-diameter sheaves 35 and 35. 7 is across.

[0009] Also, it is located on the tip side of the cord sheave base 33 parallel to the lower side of the roller chain 36. The part to which the The lower middle part is connected to the hanger 28 via the mounting bracket 39 in parallel with the roller chain 37. The distal end portion of the upper cord sheave base 33 is attached to a fixing member 41 via a mounting bracket 40. (in the case shown, to the hanger case).

0010 With the above configuration, the vane provided on the car door and the high speed door It opens and closes synchronously by engaging with a certain receiving metal fitting (not shown). The speed of the high-speed door 26, medium-speed door 29, and low-speed door 32 due to the above opening and closing. The ratio is 3:2:1.

[0011] In addition, the medium-speed door rail 22 has an auxiliary support provided on the hanger 25 of the high-speed door 26. A hanger roller 42 is installed on the hanger 28 of the medium-speed door 29 on the high-speed door rail 21. The auxiliary hanger rollers 43 provided therein are engaged with each other.

0012 With the above configuration, the auxiliary hanger roller engaged with the medium speed door rail 22 42 and an auxiliary hanger roller 43 engaged with the high-speed door rail 21. Stops the lateral swing of the rail.

[0013] 44 in the figure indicates the high-speed door rail 21, medium-speed door rail 22, and low-speed door rail 23. It is a fixture.

[0014]

【effect】

As described above, according to the three-panel horizontal sliding door according to this invention, the medium-speed door rail can be Attach the auxiliary hanger roller provided on the hanger of the high-speed door to the high-speed door rail of the medium-speed door. Engage the auxiliary hanger rollers provided on the hanger and move them to the side of the high-speed door rail. In order to stop vibration, there are no inconveniences such as having to reinforce or increase the thickness of the rail. It is possible to eliminate the misalignment.
