Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in passenger conveyors such as escalators, motorized roads, etc., which are suitable for use not only by the general public but also by the elderly and the disabled.

[Problems to be solved by conventional technology and invention]

The depth of current escalator steps is approximately 400 mm, which is sufficient for general passengers to use, but when used by a physically disabled person who uses a wheelchair, etc. The downside was that it was too big to use the escalator.

On the other hand, when a disabled person or the like gets on an escalator, especially if he/she is in a wheelchair, the escalator needs to be stopped once, and when getting off, the escalator needs to be stopped once so that the person can get on and off safely.

For this reason, one or more large steps with a depth that is deep enough for a wheelchair to get on are installed in advance, and a passenger conveyor start/stop switch for disabled people is installed at the entrance. The operation ensures that this large step stops at the boarding entrance, and after a wheelchair passenger gets on board, the passenger conveyor is activated by pressing a dedicated start switch, and after a certain period of time, the large step is stopped at the destination floor. Recently, a passenger conveyor has been proposed that can be stopped again with the user's mouth and can be easily used by people with disabilities.

However, such passenger conveyors are always equipped with large steps with a depth (700 mm or more) that is deep enough for a wheelchair to ride on, even if the number of steps is limited among the multiple steps. It is necessary to increase the radius of the chain gear device, etc. for the reversing drive, and the body of the passenger conveyor that houses this inevitably becomes large, which poses a problem in that the installation space is restricted.

Furthermore, as in Japanese Patent Application Laid-Open No. 59-7685, a lifting function is separately provided to push up the tread of a certain step to the position of the tread of an adjacent upper step.
A device has been proposed that substantially increases the area of the tread, but since it does not have a wheel stopper, there is a high risk of wheels falling off or falling due to vibrations when the passenger conveyor is operating, and a person with a disability must use the passenger conveyor alone. Can not do it. Furthermore, even when only the general public uses this passenger conveyor, the mechanism that pushes up the treadle is activated, so when passengers run up the steps from below, they can trip on the protruding treadles and get injured. This can be dangerous.

The present invention has been made in view of the above points, and an object of the present invention is to provide a passenger conveyor that can be used safely and securely not only by the general public but also by a single handicapped person.

[Means for solving problems]

According to the present invention, the treadboards of any two adjacent steps of a plurality of steps constituting a passenger conveyor are configured to be movable in the vertical direction with respect to the respective steps, and the upper step of the two steps has a A first elevating mechanism is provided for moving the tread of the upper step to a position where there is no step difference of more than a predetermined distance from the tread of the upper step adjacent to the upper step; It is equipped with a second elevating mechanism that moves the tread of the lower step so as to maintain it at the same height as the tread of the upper step, and a movable inclined plate is provided at the rear end of the tread of the lower step. be.

[Effect]

With the above configuration, when a wheelchair user uses a passenger conveyor, it is possible to secure not only a space for the wheelchair to ride, but also a space for the treads without fear of falling.

(not shown) is provided.

Reference numerals 41 and 42 denote drive devices that move the switching guide rails 39 and 40 in the vertical direction, and a similar drive device (not shown) is also provided on the switching guide rail that guides the roller 19. Similarly, switching guide rails and drive devices are provided in the upper layer as well.

Next, the operation of the apparatus of the present invention will be explained using the drawings. During normal operation, the lower step 4 for disabled persons
As shown in FIGS. 2a and 4a, the upper step 4' for disabled persons is mounted on rollers 10, 20 and 10' as shown in FIGS. 3a and 4a. Since the steps 9, 19 and 9' only contact the switching guide rails 39 and 40 near the entrances and exits in the lower and upper parts of the escalator, the external structure and movement are no different from normal steps. Here, when a disabled person in a wheelchair comes to the boarding entrance of the lower level shown in Fig. 1 and presses the stop switch S1 for disabled people, for example, a protrusion provided only on the step 4 for disabled people on the lower level is activated. A well-known detection mechanism detects when the step 4 for disabled persons on the lower level rotates to the entrance of the lower level and stops the escalator.

Next, when the handicapped step 4 stops at the entrance, the switching guide rails 39 and 40 are moved upwardly by the drive devices 41 and 42, which are hydraulic devices, etc., as shown in FIGS. 4a to 4b. This action causes the levers 10, 10' to
The rollers 9, 9' provided on the levers 10, 10' are rotated clockwise around the pins 11, 11' against the spring pressure of the levers 43', and the rollers 9, 9' provided on the levers 10, 10' are in a state of running on the guide rail 44.

Next, when the wheelchair gets on the steps 4 and 4' for disabled people and presses the activation switch S2 for disabled people,
This time, the switching guide rail (not shown) provided near the switching guide rail 39 of the lower handicapped step 4 is moved upward by a drive device (not shown) consisting of a similar hydraulic device, etc., and this operation causes the lever 20 to move upwardly. rotates clockwise around pin 21. This rotational movement of the lever 20 is caused by the chain gear 22,
24, 24', 26, 26', 28 and chains 23, 25, 27 wound around these chain gears, the pin 28a is rotated clockwise.
Gear 28' fixed to 8a, gear 30, pin 1
6b, the chain gear 29, the chain 31, and the chain gear 32 to rotate the shaft 12a counterclockwise.
The inclined plate 12 fixed to 2a is stopped at the position shown in FIG. 4b to act as a car stop. After that, the escalator starts operating, and the levers 10 and 10' rotate clockwise (counterclockwise near the upper exit) in response to changes in the inclination angle of the guide rail 44. Roller 3 according to
3 and 36 are guided by the notches 10a and 10'a provided in the levers 10 and 10', respectively, and their positions change, and this change is transmitted through the link mechanism to the tread plates 5 and 5' of the steps 4 and 4' for disabled persons. As shown in FIG. In addition, the tread 5 of the lower step 4 for disabled persons is raised to the same level as the tread 5' of the upper step 4' for disabled persons, as shown in Figures 1 and 4c. Raise it to keep it at the same height.

Next, when the steps 4, 4' for the disabled reach the exit of the upper floor, the escalator is automatically stopped. is moved downward by a drive device such as a hydraulic device, and in FIG. 4B, the lever 20 is rotated counterclockwise around the pin 21 via the roller 19. The rotational movement of this lever 20 is controlled by a chain gear 22,
24, 24', 26, 26', 28 and the chains 23, 25, 27 wound around these chain gears, the pin 28a is rotated counterclockwise, and the gear 28' fixed to the pin 28a is rotated. Gear 30, pin 16b, chain gear 29, chain 31, chain gear 32
The shaft 12a is rotated clockwise through the shaft 1
The inclined plate 12 fixed to 2a is returned to the state shown in FIG. 4a. (This state is the same as the state in which the wheelchair can get off when the wheelchair stops on the lower floor during descending operation.) Next, after the disabled person gets off the escalator, when the recovery switch S3 is pressed, the disabled person on the upper and lower floors of the upper floor The switching guide rails (not shown) of the switching steps 4', 4 are moved downward by a drive device (not shown) consisting of a hydraulic device or the like, and in FIG. , the springs 43, 43' rotate counterclockwise about the pins 11, 11' and return to the state shown in FIG. 4a, which is no different from a normal step.

In the above description, a case has been described in which a handicapped person gets on an escalator from a lower floor and gets off at an upper floor. However, the present invention can be carried out essentially the same even when a person gets off at a lower floor.

〔Effect of the invention〕

As described above, according to the present invention, only when a handicapped person uses a passenger conveyor, the height difference between the treads of two adjacent steps of a plurality of steps of the passenger conveyor and the step above the step does not exceed a predetermined value. In addition, since the wheelchair can be moved vertically at the same height, there is enough space for even large wheelchairs to ride forward, and the sloping plate installed at the rear end of the tread can be moved to act as a wheel stop. Therefore, even if there is only one person with a physical disability, they can ride the passenger conveyor safely. or,
Normally, the steps are exactly the same size as a general passenger conveyor, so the sprocket for reversing the steps is the same size as the sprocket of a conventional passenger conveyor, and the overall size of the passenger conveyor does not become unnecessarily large. .
