Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in escalators, motorized roads, and other passenger conveyors that are suitable for use by elderly people, disabled people, and the like.

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, in such a passenger conveyor, even if there is a limited number of steps among the multiple steps, the large steps (700 mm or more) that are deep enough for a wheelchair to get on are reversed at the entrance. The radius of the chain gear device for reversing drive, etc. became large, and the body of the passenger conveyor that housed it became large, resulting in a problem that the installation location was restricted.

The present invention has been made in view of the above points, and has a structure in which the tread of any step can be freely pulled out in the depth direction, and only when used by a physically disabled person, the tread is substantially widened, and a small size large enough for a wheelchair to ride on. The purpose is to provide a man conveyor.

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

Figure 1 is an overall side view of an escalator showing the present invention, where 1 is the escalator body, 2 is a handrail, and 3 is a step for general passengers, and the depth dimension is approximately as described above.
It is 400mm. Reference numeral 4 designates a step for the handicapped, which has a tread that can be freely pulled out in the depth direction, as will be described later. S1 is a stop switch exclusively for handicapped persons, and when a handicapped person wants to use the escalator, if he or she presses this switch S1, the steps for handicapped persons are automatically stopped at the entrance, and then the treadle is pulled forward by a mechanism to be described later. S2 is a handicapped person-specific activation switch that is activated after the handicapped person gets on the escalator, and S3 is a recovery switch for storing the handicapped person step 4 back to its original position.

Figures 2a and 2b are enlarged perspective views of the step 4 for disabled people, and Figure 2a shows the normal state with the footboard 5 stored, and the depth dimension L is about the same as that of the step for general passengers. It is 400mm. Also, the second
Figure b shows the state in which the footboard 5 is pulled out so that it can hang down sufficiently even in a wheelchair when used by a disabled person. A rotatably mounted roller, lever 9, is fixed to one end of a shaft 10 rotatably supported via a bearing on the side of the step 4 for the disabled, and is normally located between the lever 9 and the side of the step. It is pulled toward the rear wheel 7 by a spring 11 provided at the rear wheel 7 and comes into contact with a stopper 12 . 13 An inclined plate that functions as a wheel stopper for a wheelchair, and is fixed to a shaft 13a rotatably provided at the tip of the footboard 5. Denoted at 14 and 14' are fan-shaped guide plates for guiding the wheelchair so that the wheelchair does not lean too close to the skirt panel side, and are rotatably provided on both sides of the step by pins 14a and 14'a (not shown). .

Fig. 3 is an enlarged side view showing the inside of the step 4 for the handicapped; Fig. 3a is the normal case, and Fig. 3b is the upper landing when the tread 5 is pulled out so that the handicapped person can get on.

9 has a link 30 and pins 30a, 30b at the tip.
A closing plate 31 that closes the hole when the footboard 5 is pulled forward is rotatably attached thereto.
Further, the closing plate 31 is rotatably connected to the front end of the footboard 5 via a pin 5a. 32 is a gear fixed to the arm 27 side of the shaft 26; 33 is a gear fixed to one end of a shaft 34 rotatable in the width direction of the step 4 for the disabled; and a chain is connected between the gear 32 and the gear 32; 35 is wrapped around it. Pinions 36 are fixed to both sides of the shaft 34, and mesh with a rack 37 provided on the back surface of the footboard 5 to form a rack and pinion mechanism. 8' is a roller rotatably attached to the lever 9' by a pin 8'a;
The lever 9' is fixed to one end of a shaft 40 which is rotatably supported via a bearing on the side opposite to the side on which the lever 9 of the step 4 for the disabled is provided, and normally, like the lever 9, It is pulled toward the rear wheel by a spring (not shown) provided between the lever 9' and the side surface of the step. Reference numeral 41 denotes a gear fixed to the other end of the shaft 40, and an arm 2 having the same function as the arm 27 described above is provided at the other end of the shaft 40.
7' is also fixed. A gear 42 is fixed to one end of a shaft 43 that is rotatable in the width direction of the handicapped step 4, and a chain 44 is wound between it and the gear 41. 45 is a pinion fixed to both sides of the shaft 43, 46 is a chain gear fixed to a shaft 46a rotatably supported on both sides of the front end of the tread plate 5, and 47 is rotatable on both sides of the rear end of the tread plate 5. A chain gear 46 is fixed via the shaft 13a of the chain gear 46, and a chain 48 is wound around the chain gear 46. A rack 49 is fixed to the chain 48 and meshes with the aforementioned pinion 45 to form a rack and pinion mechanism. 51 in Figure 3 is the front wheel 6
The guide rail 52 is a guide rail for guiding the rear wheel 7, and the reference numeral 53 is a switching guide rail that can be moved up and down by a drive device 60, such as a hydraulic device, in a cutout portion of the guide rail 52.

Next, the operation of the apparatus of the present invention will be explained using the drawings.

During normal operation, the handicapped step 4 is operated by levers 9 and 9', as shown in Figures 2a and 3a.
Since the rollers 8 and 8' provided in the escalator only contact the switching guide rail 53 near the entrances and exits in the upper and lower parts of the escalator,
The external structure and movement are no different from normal steps. Here, a disabled person in a wheelchair
When a person comes to the boarding entrance of the upper floor shown in the figure and presses the handicapped stop switch S1, the step 4 for the handicapped is activated by a well-known detection mechanism that uses a limit switch to detect, for example, a protrusion provided only on the step 4 for the handicapped. When the escalator rotates toward the upper entrance, it detects this and stops the escalator. Next, the switching guide rail 53 is moved upward by a drive device 60 consisting of a hydraulic device or the like, and this operation causes the lever 9 to rotate clockwise about the shaft 10 against the spring pressure of the spring 11. This rotational movement of the lever 9 corresponds to the shaft 10, gear 21, gear 22, shaft 23, gear 24, gear 2 in FIGS.

Chain 44, gear 42, shaft 43 and pinion 4
5. Connect the chain 48 through the rack 49 in Fig. 6a.
In order to move in the direction of the arrow, the inclined plate 13 rotates about 60 degrees counterclockwise about the shaft 13a and stops at the position shown in FIG. 6b, thereby acting as a wheel stop. Thereafter, the escalator starts operating, and when the handicapped step 4 reaches the exit of the lower floor, the escalator is automatically stopped. When the handicapped step 4 stops at a predetermined position at the exit, the switching guide rail (not shown) on the lower floor on the opposite side is moved downward by a drive device (not shown) consisting of a hydraulic device, etc. to rotate the lever 9' together with the shaft 40 in the counterclockwise direction. This rotational action of the lever 9' rotates the guide plate 14' on the opposite side counterclockwise around a pin (not shown) via the shaft 40, arm 27', and link (not shown). , the chain 48 is moved in the direction of the arrow in FIG. Rotate it 60 degrees so that the wheelchair can be dismounted as shown in Figure 6a.

Next, when the disabled person presses the recovery switch S3 after getting off the escalator, the switching guide rail (not shown) on the lower floor is moved downward by a drive device (not shown) consisting of a hydraulic device, etc., and the lever is moved through the roller 8. 9 is rotated counterclockwise together with the shaft 10. The rotational movement of this lever 9 consists of a shaft 10, a gear 21, a shaft 23, a gear 24, a gear 25, a shaft 26,
The guide plate 14 is rotated counterclockwise around the pin 14a via the arm 27 and the link 28, and the blocking plate 31 is pulled into the inside of the step 4 for the disabled via the shaft 26, the arm 29 and the link 30, and the shaft is rotated. 26, gear 32, chain 35, gear 3
3. The step board 5 is pulled back via the shaft 34, pinion 36, and rack 37 to reduce the size to the same size as a normal step.

As explained above, the present invention is such that the tread of at least one of the plurality of steps of the passenger conveyor is configured such that the tread can be freely pulled out in the front and back direction, and the tread of the step can be pulled out only when a disabled person uses the passenger conveyor. Because of this, even a disabled person using a wheelchair can safely ride the conveyor alone, and the sprocket for reversing the steps remains the same size as before, so the body of the passenger conveyor does not become unnecessarily large.
