Description

Access device

technical field

The present invention relates to an entrance/exit device arranged on an elevator car or an elevator hall side of a building.

Background technique

In general, an elevator doorway device is configured to open and close a doorway by moving an elevator door called a hall door in a lateral direction along a sill located below. The guide shoe protrudingly provided on the lower part of the hall door is fitted into the sill groove provided on the sill to suppress the hall door from shaking in the front-rear direction. The entrance and exit devices arranged on the elevator car that ascends and descends up and down and the entrance and exit devices arranged on the building both have the above structure, so that the elevator doors can be opened and closed in a linked manner. According to the regulations of the law, in the above-mentioned entrance and exit device, the gap between the hall door and the threshold should be set at 6mm or less.

When a strong earthquake occurs, the opening of the building where the entrance and exit device is provided temporarily deforms in the vertical direction, and the hall door and the threshold interfere. As a result, the hall door may come out of the sill groove, or the hall door may be bent and deformed. A warped hall door often comes out of the sill groove. When the above situation occurs, the hall door may not be able to be opened or closed. At this time, it is necessary for emergency personnel to cut off or destroy the hall door to rescue the passengers in the elevator car, and the rescue activities need to take a long time.

On the other hand, Patent Document 1 discloses a structure in which door feet (equivalent to the above-mentioned guide shoes) are provided at the lower part of the car door body so as to be inserted into the sill groove, When the door main body is displaced in the vertical direction, the door legs are also displaced in the vertical direction relative to the car door main body. According to this configuration, it is possible to prevent the door leg from slipping out of the sill groove.

Detailed ways

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing the entire elevator installation according to the present embodiment.

In this elevator equipment, the elevator car 3 ascending and descending in the hoistway, the main sling 2 connected to the elevator car 3 at one end and wound on the hoist 1 in the middle, and the balancer connected to the other end of the main sling 2 Heavy 4 is linked under the drive of hoisting machine 1. Furthermore, the elevator car 3 is connected below with the counterweight 4 via compensating ropes 5 (or chains or cables).

At the bottom of the hoistway, there is provided an elevator buffer 6 for buffering the elevator car 3 if it falls due to an abnormality. In the elevator buffer 6, a hydraulic shock absorber, a coil spring shock absorber, or the like is used as a shock absorber.

In addition, in the elevator installation, an access device 7 is provided at the elevator car 3 or at the elevator entrance and exit of each floor. The entrance and exit device 7 has a hall door 8 and a threshold 14 , and the hall door 8 opens and closes along the threshold 14 . In FIG. 1 , only the entrance and exit device 7 provided in the elevator lobby is shown, and the structure of the entrance and exit device 7 of the elevator car 3 is also substantially the same.

Fig. 2 is a schematic view of the structure around the entrance and exit device 7 viewed from the elevator hall of each floor.

A door guide rail 11 is provided in the upper frame body 10, and the hall door 8 is suspended on the door guide rail 11 by a door suspension member 9, and is opened and closed by a door driver not shown. In addition, the upper end portion and the left and right side end portions of the hall door 8 are covered by a door frame 17 .

A sill 14 having a sill groove (not shown) extending in the longitudinal direction is provided below the hall door 8 .

In addition, the hall door 8 is configured such that the upper member and the lower member of the main body of the hall door 8 are connected so as to be relatively displaceable in the vertical direction, and a guide shoe (not shown) is provided on the lower portion of the main body. The hall door 8 opens and closes along the sill 14 with the guide shoe fitted into the sill groove. In addition, when the hall door 8 is stressed in the vertical direction, the upper member and the lower member are relatively displaced in the vertical direction, so that the height of the hall door 8 is reduced.

According to this structure of the present embodiment, when the hall door 8 interferes with the sill 14, bending deformation does not easily occur.

FIG. 3 is a structural diagram showing an example of the structure around the hall door 8 and the sill 14 .

In the entrance/exit device 7 , the hall door 8 adopts a structure in which an upper member 13 and a lower member 18 are connected to each other, and a guide shoe 15 is installed on the lower part of the hall door 8 via a bracket 19 . In the example of FIG. 3 , the upper member 13 forms the main body of the hall door 8 and the lower member 18 forms the cover. The bracket 19 is attached to the lower portion of the upper member 13 forming the main body of the hall door 8 and penetrates the lower member 18 forming the cover. The above structure is merely an example, and the bracket 19 may also be attached to the lower portion of the lower member 18 . In this case, the length of the bracket 19 can be set very short. In addition, the guide shoe 15 may be directly attached to the lower portion of the lower member 18 without using the bracket 19 . In addition, an elastic body (such as a spring) 16 is arranged between the upper member 13 and the lower member 18. When receiving a force in the vertical direction, the upper member 13 and the lower member 18 utilize the elasticity of the elastic body 16 to perform relative displacement in the vertical direction. The height of hall door 8 is reduced.

Since the structure shown in Fig. 3 is adopted, when an earthquake that vibrates mainly in the up and down direction occurs, when the ceiling and the floor of the building are displaced in the direction approaching each other due to the shaking of the building, due to the Since the height of the door 8 decreases as it vibrates up and down, the interference between the hall door 8 and the sill 14 can be alleviated, thereby preventing the hall door 8 from being unable to open and close due to deformation such as bending.

In addition, as shown in Figure 3, since the elastic body 16 is provided between the upper member 13 and the lower member 18, the hall door 8 can expand and contract when it interferes with the threshold 14, and can return to its original length after the interference disappears. , so that it can quickly return to the open and close state.

In addition, as shown in FIG. 3, since the length of the guide shoe 15 including the bracket 19 is lengthened, and the depth of the sill groove is deepened, the hall door 8 is more difficult to escape from the sill groove. The depth of the portion of the guide shoe 15 embedded in the sill groove is preferably set to a depth that does not come out due to a relative displacement that may occur between the sill 14 and the hall door 8 . For example, the length of the bracket 19 to which the guide shoe 15 is attached and the depth of the sill groove of the sill 14 can be set to about twice the normal ones. In addition, it is preferable to leave a space between the guide shoe 15 and the bottom of the sill groove of the sill 14 , which is large enough to avoid interference when an earthquake or the like occurs.

In addition, in this structural example, the connecting portion of the upper member 13 and the lower member 18 is provided at the lower portion of the hall door 8 . For example, the height of the lower member 18 is set to about several centimeters. Thereby, the connection part of the upper member 13 and the lower member 18 is less conspicuous.

FIG. 4 shows a configuration diagram of another configuration example around the hall door 8 and the sill 14 .

In the structural example of FIG. 4 , unlike the case of FIG. 3 , the upper member 13 forms the cover of the hall door 8 , and the lower member 18 forms the main body of the hall door 8 . Furthermore, a bracket 19 is mounted on the lower portion of the lower member 18 . In addition, as in the case of FIG. 3 , an elastic body 16 is provided between the upper member 13 and the lower member 18. When receiving a force in the vertical direction, the upper member 13 and the lower member 18 utilize the elasticity of the elastic body 16 to move upward and downward. Relative displacement makes the height of hall door 8 dwindle.

In this structural example, the connecting portion of the upper member 13 and the lower member 18 is located on the upper part of the hall door 8 , specifically in the upper frame body 10 or the door frame 17 . Therefore, the connection part is hidden in the upper frame body 10 or the door frame 17, and the connection part cannot be seen from the outside.

In this structural example, the guide shoe 15 is attached to the lower member 18 via the bracket 19, and the guide shoe 15 is displaced in the vertical direction as the length of the hall door 8 changes. Therefore, the guide shoe 15 does not interfere with the bottom of the sill groove of the sill 14 to be deformed or damaged.

In addition, in this configuration example, since the guide shoe 15 is displaced as the hall door 8 expands and contracts, the distance between the guide shoe 15 and the bottom of the sill groove of the sill 14 can be further reduced compared to the case of FIG. 3 . Thereby, the length of the guide shoe 15 including the bracket 19 and the depth of the sill groove can be set to substantially the same size.

FIG. 5 shows a configuration diagram of still another configuration example around the hall door 8 and the threshold 14 .

The structural example of FIG. 5 is the same as the structural example of FIG. 4 in that the cover of the hall door 8 is formed by the upper member 13 and the main body of the hall door 8 is formed by the lower member 18 .

In the structural example of FIG. 5 , no elastic body is formed between the upper member 13 and the lower member 18 , and the connection method between the upper member 13 and the lower member 18 is different from the structural example of FIG. 4 .

FIG. 6 is an explanatory diagram of a connection method in the configuration example of FIG. 5 .

As can be seen from FIGS. 5 and 6 , an elongated hole 21 extending in the up-and-down direction is formed on the upper member 13 , and the bolt 22 is screwed into the lower member 18 through the elongated hole 21 , thereby fixing the upper member 13 on the lower member 18 . At this time, when the hall door 8 is subjected to a certain force in the vertical direction, the bolt 22 moves in the slot 21, and the upper member 13 and the lower member 18 are relatively displaced, so that the height of the hall door 8 is reduced.

According to this structure, since the height of the hall door 8 decreases when it interferes with the sill 14 , the hall door 8 does not easily bend or deform due to interference with the sill 14 . When this structure is adopted, the structure can be simplified and the cost can be reduced, but since the elastic body 16 is not provided, the length of the hall door 8 will not return to the original length. However, since no bending or deformation occurs, the original state can be easily restored by repositioning the relative positions of the upper member 13 and the lower member 18 .

The above-mentioned embodiments of the present invention are examples for describing the present invention, and the scope of the present invention is not limited to the above-mentioned various embodiments. The present invention can be implemented in various other ways without departing from the gist of the present invention.
