Abstract

PROBLEM TO BE SOLVED: To enable large-sized objects such as a wheelchair and a large-sized cargo to be loaded by providing a plurality of steps adjacent to upper normal steps in an escalator, for continuously forming a large-sized object loading horizontal surface and an intermediate step to be interposed between a plurality of steps and lower normal steps, and providing exclusive tracks to respective steps. SOLUTION: In an inclined traveling part, lower normal steps 10, 11, an intermediate step 21, an additional step 31, a large-sized object loading normal step 32, and upper normal steps 41, 42 are sequentially provided, and main wheels (step wheels) and driven wheel trailer wheels are provided on respective steps. Tracks (main tracks 71 to 73 and driven tracks 81 to 83) in relation to respective wheels are provided outside a skirt guard panel into a step shape. When the steps enter the inclined traveling section from the horizontal traveling section, they are guided by respective individual tracks so as to automatically constitute a large-sized object loading related part. In this case, a riser on the intermediate step 21 is enlarged, and the inclined angle on the part is increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an articulated conveying device including an escalator having steps capable of mounting large objects such as wheelchairs and large cargo, and is installed in public passages, business establishments, etc. By doing so, it contributes to the improvement of convenience and welfare.

[0002]

2. Description of the Related Art As an escalator capable of mounting a large-sized object such as a wheelchair, a number of methods have been developed and put into practical use. It is equipped with a mechanism that transforms the steps into a wheelchair-mountable body, requires the attendance of an attendant when the mechanism is activated, eliminates ordinary users, and requires a few minutes of travel stoppage, which is inconvenient for general users. It has the drawback of having to endure. Moreover, the structure tends to be complicated and expensive.

[0003]

[Problems to be Solved by the Invention] A complicated mechanism is not used for creating a space for mounting a large-sized object such as a wheelchair, and the space immediately appears automatically, and the wheelchair (passenger We will develop a concatenated transport device that can be loaded (on board) and can be used by wheelchair users to get on and off at short speeds or at extremely low speeds. Of course, it can be conveniently used not only for wheelchairs but also for transporting large cargo.

[0004]

[Means for Solving the Problems] While respecting the shape of the step surface of the step of the conventional escalator as much as possible, the step to be added to form a horizontal tread group for mounting a large object (one or more steps). , And the intermediate additional steps (0 or more) from the normal step to the additional additional step, each of which has a separate track, and which are connected by a connecting element such as a chain or a link. Connected so that all treads are in the same horizontal plane in the horizontal running section, and in the turning section and the backside return section,
The track is configured to have as little space as possible and eliminate play in connecting elements such as chains. However, a safety mechanism will be provided if necessary. If the position where the track is provided is insufficient below the step,
It is also necessary to provide it on the outside of the skirt guard panel, below the moving handrail, and, correspondingly, to provide the support portion of the axle on the extension of the step. The inclination angle of the inclined traveling part is 3
It is also possible to adopt a smaller angle instead of sticking to 0 °, and consider installing the wheelchair laterally by expanding the lateral width of the step instead of sticking to mounting the wheelchair in the front-back direction. . Also keep in mind dimensions that are suitable for walking on escalators. In this way, we try to develop a structure that is as simple as possible and that satisfies the required functions.

[0005]

Operation When the vehicle enters the inclined traveling section from the horizontal traveling section, it is guided to each individual truck, and a large-sized object-related part such as a wheelchair is automatically constructed. At that time, the kick-up of the intermediate step portion is enlarged, so that the inclination angle of the portion is increased. If a car stop mechanism is required for safety, the switch shall be operated so that the mechanism works before the start of travel. It goes without saying that the bollard mechanism should actuate the switch so that it is retracted before the comb. If the wheelchair is exclusively for horizontal loading, the car stop mechanism is not required. Since a special wheelchair-mounting part creation mechanism is not required, no related check mechanism or operation of a staff member is required, and it can be used without a staff member. For the sake of safety, it is not obstructive to leave staff, but it is necessary to check the entry position and the position of buttons for start / stop so that it is not necessary.

[0006]

EXAMPLES The description begins with an example of the invention which is relatively practical. FIG. 1 shows a step in an inclined traveling stroke in the case of one additional step (for mounting a large object) and one intermediate step, (a)
Is a side view, FIG. 2B is a sectional view taken along the line Aa, and FIG. 2 is an overall schematic side view of the same system. In the inclined traveling section, if the order of steps is shown by way of example, from the bottom to the lower normal steps 10, 11, the intermediate step 21, the additional steps 31, the large-sized normal step 32, and the upper normal steps 41. , 42. Each step has a main wheel (step wheel) and a sub-wheel trailer wheel, and each step 5 or 6 is represented by a reference sign of the step, and the same display also indicates its center. For example, it looks like 512,631. The main wheel axles are connected in sequence by connecting elements (chain links, etc.) 7. Assuming that the running inclination angle of the normal step is α, the depth of the tread is A, and the kick-up is H, H = Asinα
There is a relationship. The main wheels do not have to be evenly spaced, but they should have a uniform value D in order to simplify the structure and manufacture. Triangle 531-511-53 with wheel center as vertex
2, the side length and angle are represented as shown, and 2D
Since / sinα = D / sinβ and α ₁ = α + β, α ₁ = α + arcsin (0.5 sinα), and the lift H ₁ before and after the intermediate step is H ₁ = Asin α ₁
Becomes Numerical examples are shown below, where D = A and A = 40
If 0 mm and α = 30 °, H = 200 mm, α ₁ =
44 ° 29 ′, H ₁ = 280.2 mm, but according to the actual example, the maximum allowable rise of public stairs is about 300.
In mm, it is within the allowable limit, and A =
If 400 mm and H = 160 mm, α = 23 ° 3
5 ′, α ₁ = 35 ° 07 ′, H ₁ = 230.10 mm, which are suitable values. 1 and 2 show an example in which this value is adopted. In either case, the tracks for each wheel (main tracks 71, 72, 73, sub-tracks 81, 82, 83
Are provided in a stepped manner on the outside of the skirt guard panel 9 to avoid interference. Wheelchairs are commonly referred to as 00 hereafter regardless of whether they are placed vertically or horizontally.

In the case of one additional step, in order to simplify the structure, A = 400 mm and H = 160 mm, and when the intermediate step is omitted, the result is as shown in FIG. 3, where α ₁ = 2α
= 47 ° 10 ', H ₁ = 293.33 mm, and the kick up is within the allowable limit. In this case, the track is provided under the step, the structure of the step is simplified, and it is advantageous in strength.

In any of the above cases, the small and medium-sized wheelchair is shown in FIG.
As shown in FIGS. 3 to 3, if the toes are directed downward, the car stop 6 is necessary but can be mounted. In order to eliminate the fear of passengers, it is good to expand the width of the tread and mount it sideways. The size limit of a large wheelchair is 700 mm in width and 1200 mm in front-rear length, so there is a margin for the width, and if the lateral width B of the tread is about 1250 mm, it can be sufficiently mounted on the side.

If a large wheelchair is placed in the front-rear direction, it is necessary to increase the front-rear width (depth) A of the tread surface or increase the number of additional steps. As shown in FIG. 4 below, in the case of two additional steps and two intermediate steps, α ₁ =
α + arcsin (2/3 · sin α), H ₁ = Asi
It is represented by nα ₁ . Similar to the case of a normal escalator, if A = 400 mm and α = 30 °, α ₁ = 49 ° 2
7 ', H ₁ = 303.94 mm, and the kick up slightly exceeds the allowable limit. However, in order to avoid the interference of the truck, the positions of the auxiliary wheels are made deeper, or the positions of the auxiliary wheels are moved horizontally as shown in FIG. 4, and the shapes of the additional steps 31, 32 and the intermediate steps 21, 22 are formed. To change.

When the rise of the normal step is reduced to two additional steps and one intermediate step, A = 400 mm, H =
Using 160 mm and α = 23 ° 35 ′, α ₁ = 2α
= 47 ° 10 ′, H ₁ = 293.33 mm, which is within the allowable range, and the positions of the follower wheels and the shape of the steps are slightly changed as shown in FIG. However, the track 83 for the secondary wheel 631
Although the ceiling is omitted, a mating surface (perpendicular to the tread surface) 312 between the tread surfaces 31 and 32 is provided to prevent the step from being released.

When the above configuration is generalized, the number of steps for mounting a large object is m (m = 2, 3, ...) And the number of intermediate steps is n.
If (n = 0, 1, 2, ...), the number of additional steps is m−
1 is (m−1) A / sin β = (n + 1) A / sin
α, H = A sin α, α ₁ = α + β, H ₁ = A s
in α ₁ , and thus the following relationship is obtained. H ₁ = A sin (α + β), α = arcsin (H
/ A), β = arcsin [(m−1) / (n + 1) ·
sin α]

In order to keep the tension of the step chain constant, a large number of steps are arranged in the step row so that a constant number of groups are always maintained in the inclined traveling section (the sum of the groups in the transition section between the horizontal and the inclination). Exist as a group).
FIG. 6 shows a case where there are always two large-sized step groups on the inclined traveling section, and L is the distance between the groups. In order to deal with the deviation of the total length of the step chain and the track that may still occur, the turnback portion 76 at the end of the track has a structure in which the position can be slightly adjusted in the horizontal direction, and a spring 77 is provided as illustrated in FIG. It is desirable to keep the tension of the chain. At that time, a comb-like joint portion 78 is provided so that a gap is not formed in the rail.

[0013] A car stop when mounted on a wheelchair is not necessary when it is placed sideways, but it is necessary for safety when placed vertically, and a crank mechanism or a rack and pinion mechanism (not shown) is suitable for putting in and out. The mechanism may be driven by running from a step, but it is easy to use a dedicated small electric motor, and the automatic operation of pulling out the car stop before mounting and pulling the car stop before departure is easy to use. Can be done using. To get in, just push a button and the closest group of large-sized steps will be stopped by the action of the proximity switch.
If you press the button before or after loading, the car stop will be released if necessary, and when it is confirmed, the car will start moving. When the vehicle comes close to the stop point, it is decelerated by the action of the proximity switch, and further, if necessary, the vehicle is stopped. These operations are performed by the program controller, and can be operated safely without calling in the workers, the required time is short, and it is not necessary to exclude general passengers. If you do not have a wheelchair on, you can drive normally and walk on steps without any difficulty.

What has been described so far is a case in which a group of steps related to mounting a large object is connected in a series of chains, and the existence position of the group is limited in order to keep the chain tension constant. The above limitation is not required if the step group is connected by a side line chain connected to. In this case, the length of the main line chain between both ends of the side line is a value obtained by multiplying A by the number of steps (m + n) for mounting large items. FIG. 8 shows m =
2, n = 1 (corresponding to FIG. 1, α ₂ and β ₂ correspond to α ₁ and β ₁ , respectively, and so on), and FIG.
10 corresponds to FIG. 4, and FIG. 11 corresponds to FIG. If the general formula is shown, the length between the side line chain terminals of the main line chain 7 = (m +
n) A, the length of the horizontal portion 7a of the lateral line chain = (m-1) A, the angle between the inclined main line and the horizontal lateral line = α, the angle between the inclined portion 7b of the lateral line chain and the main chain 7 = β ₂ , The angle between the horizontal side line 7a and the inclined side line 7b = α ₂ , and applying the sine law to the triangle surrounded by the main line chain 7 and the side line chains 7a and 7b, sin α ₂ / (m + n) A = sin β ₂ / ( m-1)
A, α ₂ = α + β ₂ is obtained, and when this is rearranged, tan α ₂ = sin α / [cos α- (m-1) / (m
+ N)] is obtained, and the uniform rise H ₂ in the middle part is H ₂ = Asin
It is represented by α ₂ . Estimating the respective cases, the case of FIG. 8: m = 2, n = 1, α = 30 °, A = 40
0 mm, α ₂ = 43 ° 11 ′, H ₂ = 273.
73 mm; FIG. 9: m = 2, n = 0, α = 30 °, A = 40
0 mm, α ₂ = 53 ° 43 ′, H ₂ = 322.
It was 78 mm, and the kick was too large. Therefore, H = 160
mm, α = 23 ° 35 ′, α ₂ = 46 ° 0
9 _', H 2 = 288.55'mm and turned to enter the permissible range, the case of FIG. 10: m = 3, the case of n = 2, α = 30 °, A
= 400 mm, α ₂ = 47 ° 01 ′, H ₂ =
292.62 mm, which is within the allowable range, and in the case of FIG. 11: m = 3, n = 1, A = 400 mm,
Using H = 160 mm and α = 23 ° 35 ′, α ₂ =
45 ° 02 ′, H ₂ = 287.90 mm, which is within the allowable range.

The horizontal side wire chain 7a may have the same size as the main line chain 7, but the inclined side wire chain 7b needs to be changed in pitch in consideration of the wheel interval. In addition, the structure must be such that the main line chain does not interfere with the axle between the side line terminals.

According to the present invention, each step is simply guided by an existing truck to move, and a large object mounting step group is repeatedly generated and eliminated while moving, and a large object is fixed at regular intervals. Since the mounting surface comes to the entry point, it can be mounted in a short waiting time, the time for forming the mounting surface is not required, the waiting time is short, the safety level is high, there is no need to exclude general passengers, and It is easy to walk on the steps and can be used with wheelchair passengers, so it eliminates bothersome feelings and annoyances. There is no fear that the cost for equipment will be particularly high.
It can be used not only for wheelchairs but also for carrying large-sized luggage to be carried, so it is also suitable for use at airports.
