Description

Description: TECHNICAL FIELD The present invention relates to an escalator device, and more particularly, to an escalator device capable of mounting a carrier such as a shopping cart.

BACKGROUND ART Generally, an escalator device is disclosed in, for example,
As described in Japanese Patent No. 3993, a plurality of steps that are installed straddling the upper floor side and the lower floor side and connected endlessly between the upper and lower floors are rotated.

The escalator device having the above-described configuration is installed for use by general passengers, and the movement of a cart such as a shopping cart to another floor is performed exclusively by using a gently inclined electric road. However, the electric road has a problem that a large installation area is required because the inclination angle cannot be made large, and the transport vehicle must be supported in an unstable posture because the tread is continuously inclined. There was a problem.

DISCLOSURE OF THE INVENTION One of the objects of the present invention is to provide an escalator device on which a carrier can be mounted.

Another object of the present invention is to provide a safe escalator device in which a carrier can easily enter.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a traveling system comprising an upper horizontal section, a convex curved section, an inclined section, a concave curved section, and a lower horizontal section on a frame installed over an upper floor and a lower floor. An escalator device provided with a road and circulating and moving a plurality of steps connected endlessly along the traveling path, wherein: It is configured such that three or more steps always travel in each section.

When a transport vehicle is used with the escalator device, the transition from the horizontal section to the getting on / off floor and the change of the moving direction between the horizontal section and the curved section become problems. Since there is always a horizontal plane with a large depth adjacent to it, it is easy to get in the transport vehicle, and the curved section where the three steps always run has a large radius of curvature. Handling of the vehicle is facilitated, so that the transport vehicle can be mounted on the escalator device.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIG. 1 to FIG.

Generally, an escalator device is configured as follows. That is, an upper getting on / off floor 4 and a lower getting on / off floor 5 are provided at both ends in the longitudinal direction of the frame 3 installed over the upper floor 1 and the lower floor 2, and an endless space is provided between these two getting on / off floors 4,5. A plurality of steps 6 connected by the step chain are rotated. Each step 6 has a tread surface 6 having a depth dimension of about 400 mm.
Form S. These steps 6 are guided by forward and backward paths formed by guide rails 7A and 7B provided in the frame body 3 so that the front wheels 8 and the rear wheels 9 are respectively circulated.
It has.

The guide rails 7A and 7B include an upper horizontal section A adjacent to the upper floor 4 on the outward path, a convex curved section B connected to the upper horizontal section A, and an inclined section C connected to the convex curved section B.
And a concave curve section D connected to the slope section C, and a concave curve section D
And a lower horizontal section E adjacent to the lower floor 5.

Further, a balustrade panel 10 erected on the frame 3 is located on both sides of the step 6 along the traveling direction, and moves in synchronization with the step 6 along the periphery of the balustrade panel 10. The moving handrail 11 is supported by guidance.

In the above configuration, taking into account the mounting of the transport vehicle, in the present embodiment, as shown in FIG. 3, comb teeth provided at the distal end portions of the both floors 4, 5 and meshing with the cleats 6C of the steps 6 are provided. A concave curved surface 12S is formed on the upper surface of the comb body 12 having The concave curved surface 12S is formed on the upper surface from the tip of the comb teeth to the vicinity of the attachment portion to the both floors 4, 5.

Further, from the comb body 12 of the upper floor 4 to the convex curved section B
In the upper horizontal section A and the lower body 5
In the lower horizontal section E from to the concave curve section D, the three steps 6 are arranged so as to continuously form a horizontal plane and travel. Therefore, a horizontal plane having a depth dimension (length in the tread plate moving direction) of 1200 mm always exists in the horizontal sections A and E.

In the convex curve section B and the concave curve section D connected to the upper horizontal section A and the lower horizontal section E, three steps 6 are configured to travel with a step smaller than the step in the slope section C. Have been.

Next, an operation when the shopping cart 14 as a transport vehicle is moved from the lower floor 2 to the upper floor 1 by the escalator device having the above configuration will be described.

The shopping cart 14 has a storage section 15 for storing shopping or a shopping basket, a cart section 18 having a front wheel 16 and a rear wheel 17 supporting the storage section 15 and having a spacing of about 1000 mm, and a handle section 19. The user generally has a storage section
By pushing the handle 19 with the front side 15, the traveling direction of the shopping cart 14 is determined. The front wheel 16 and the rear wheel 17 are free wheels whose directions can be easily changed by a user's operation.

In order to put such a shopping cart 14 on the escalator device, as shown in FIG. 4, the shopping cart 14 is moved from the lower getting on / off floor 5 to the moving step 6. If the moving speed of the shopping cart 14 at this time is synchronized with the moving speed of the steps 6,
The shopping cart 14 can be stably moved on the steps 6 without any problem.

When the shopping cart 14 is loaded at a speed lower than the traveling speed of the steps 6, the direction of the front wheel 16 is changed by 180 degrees as shown by the two-dot chain line in FIG. Although the cart 14 fluctuates, the user is not swung around by the shopping cart 14 because it is a moment.

When the shopping cart 14 is loaded at a speed higher than the moving speed of the steps 6, it can be loaded in the state shown in FIG.

After the front wheel 16 and the rear wheel 17 of the shopping cart 14 get on the step 6, the user gets on the lower step 6 according to the moving speed of the step 6, and the handle 19 of the shopping cart 14
All you have to do is just stand still. Shopping cart 14
The moment the passenger gets in, the front wheel 16 enters the concave curve section D and the front is lifted, but the concave curve section D has a depth dimension of
It has a length of three 400mm steps 6 and a radius of 2
Since it has a gentle curvature of 500 to 3500 mm,
Lifting forward is performed gently, and the user does not lose his posture.

As the step 6 travels, the shopping cart 14 is transported from the concave curve section D to the slope section C as shown in FIG.
In the inclined section C, the shopping cart 14 has a front wheel 16 and a rear wheel 17.
Since the lifting cart is lifted higher, the shopping cart 14 moves in a downward direction on the inclined surface, but the force is small, and the force is received by the horizontal tread surface 6S of the step 6. The user can be suppressed without requiring much power.

When the traveling of the step 6 advances and the front wheel 16 of the shopping cart 14 enters the convex curve section B, the convex curve section B also has a large curvature, so that the shopping cart 14 gradually returns to the posture,
It returns to a horizontal posture in the upper horizontal section A. Shortly after entering the upper horizontal section A, the front wheel 16 has the comb body 12 at the tip of the upper getting on / off floor 4.
At this time, since the concave surface 12S is formed on the upper surface of the comb body 12 meshing with the cleat 6C of the step 6, the front wheel 16 smoothly rides on the upper floor 4 due to the inertia of the shopping cart 14. It is safe for elderly people without shock when riding. In addition, as shown by a two-dot chain line in FIG. 3, the upper surface of the comb teeth of the ordinary comb body 12 is formed with a convex curved surface m, so that the comb teeth 12 are higher in n dimension than the concave curved surface 12S, and the front wheel 16 abuts. The reaction force is transmitted to the user at the time, and the user needs to push up the shopping cart 14 with a force greater than the reaction force, but the reaction force is not enough for the young housewife.

The above description is for the case where the shopping cart 14 is moved from the lower floor 2 to the upper floor 1. However, when the shopping cart 14 is moved from the upper floor 1 to the lower floor 2, the order is reversed. Then, the shopping cart 14 may be moved.

That is, the shopping cart 14 is advanced by pushing the handle portion 19 on the upper getting on / off floor 4 with the storage portion 15 on the front side, and the tread surface 6S of the three adjacent steps 6 horizontally arranged in the upper horizontal section A as it is The front wheel 16 and the rear wheel 17 are moved, and the user stands still on the step 6 on the rear side. If the operation of the escalator device is followed in this state, the shopping cart 14 is gradually turned forward in the convex curve section B and enters the slope section C as it is. In this state, it passes through the slope section C,
As shown in FIG. 7, since the radius of curvature of the concave curve section D is large, the attitude of the shopping cart 14 does not suddenly change, and the handle portion 19 also moves from the position a to the position b as shown in FIG. The user can be relieved because it gradually changes along the radius of curvature. The shopping cart 14 held completely horizontally on the lower getting on and off floor E applies the front wheel 16 to the tip of the comb body 12 at the tip of the lower getting on and off floor 5 at this time.
Since the shopping cart 14 has inertia, the shopping cart 14 can be easily transferred to the lower getting on / off floor 5.

As described above, according to the present embodiment, three steps 6 always run continuously in the upper horizontal section A and the lower horizontal section E, and in the convex curve section B and the concave curve section D connected thereto. , It is easy to get on and off the step 6 of the shopping cart 14, and the radius of curvature of the uneven curve section becomes large, so that the direction between the upper horizontal section A, the lower horizontal section E and the inclined section C is increased. Changes in the shopping cart become slower
A large reaction force due to the 14 sudden changes in direction is not transmitted to the user.

By the way, as shown in FIG. 5, the mutual step hb of the group of steps 6 in the slope section C, which is the longest step running path of the escalator device according to the present embodiment, is 1/1 / the step depth dimension.
It is set to be not more than 2.5 and not less than the diameter of the front wheel 16 of the shopping cart 14. This step hb is 160 mm or less when the depth of the step 6 is 400 mm, and is almost the same height as the stairs of a general house (equivalent to the kick-up height of the Building Standards Law), and can be used in a familiar posture. In addition, even if a passenger accidentally pushes the shopping cart 14 strongly in the upward direction, the front wheel 16 serves as a stopper that does not climb over the step hb.

Further, as shown in FIG. 7, the step generated between the lower horizontal section E and the concave curve section D is caused by the drop of the shopping cart 14 which has come down.
It is considered to be able to correct the posture of the person. That is, the small step ha between the steps 6 located adjacent to the lower horizontal section E and the concave curve section D is smaller than the radius of the rear wheel 17 of the shopping cart 14, for example.
When the shopping cart 14 is set to 30 mm and the shopping cart 14 that has been traveling toward the lower getting on / off floor 5 is inclined with respect to the traveling direction, and the shopping cart 14 is pulled backward to correct it. The rear wheel 17 has such a size that the posture can be easily corrected over the small step ha. If the size of the small step ha is set to the height of the colored caution band at the upper end of the step riser, as shown by the two-dot chain line 16 'in FIG.
A user who pushes the shopping cart 14 and gets in the up direction,
Since the front wheel 16 of the shopping cart 14 can be stopped by hitting the small step ha, the shopping cart 14 can be stopped at the correct riding position to prevent a slipping accident.

Further, as shown in FIG. 2, the length L from the tip of the comb body 12 to the end of the balustrade, which is the dimension of the balustrade 10 projecting toward the floor, is shown.
Is set to be equal to or greater than the distance between the front wheel 16 and the rear wheel 17 of the shopping cart 14, and when the shopping cart 14 is mounted on the steps 6, when the posture of the passenger becomes unstable, the moving handrail 11
On the other hand, and from the step 6
Since the moving handrail 11 can be grasped even when descending to 5, it greatly contributes to ensuring safety.

In addition, as shown in FIG. 8, if the guide rails 7A and 7B of the lower horizontal section E are configured to be inclined at an angle of θ, for example, 1 to 5 °, and descend to the lower getting on / off floor 5, the three steps 6 may be downwardly directed. A continuous inclined plane is formed, and the shopping cart 14 and the user who get on the step 6 from the lower getting on / off floor 5 are foreseen that they will proceed toward the upward slope, and prepare mentally. Things. On the other hand, for passengers going down, the comb body of the shopping cart
It is easy to get off by using the weight movement power toward 12.
Further, by inclining the lower horizontal section E, the movement to the adjacent concave curve section D can be made gentler.

In each of the embodiments described above, a. The length of the horizontal section is 1200 mm or more b. The distance between the front and rear wheels of the shopping cart is 1000 mm or less c. The length of the uneven curve section is 1200 mm or more d. Escalator installation angle of about 20 ° e. Most preferably, the radius of curvature of the curved section is 2500-3500 mm, which is based on verification of a monitor test.

Next, a monitor test using the escalator apparatus according to the present embodiment using a shopping cart will be described.

A general escalator device conforming to the Building Standards Law and the escalator device according to the present embodiment were installed in a factory.

In general, the escalator device has an inclination angle of 30 °, a tread surface of a step in a lower horizontal section is 1.5 sheets, and a concave curve section has a radius of curvature of 1200 mm and a length of 628 mm.

The escalator device according to the present embodiment has a tilt angle
At 20mm, the lower horizontal section has three treads and the concave curve section has a radius of curvature of 2500mm and a length of 872mm.

The depth of the tread of the steps of both escalator devices was 400 mm, and the test was performed at running speeds of 20 m / min and 30 m / min. The shopping carts used were shopping carts of three companies having a front-rear wheel and rear-wheel center dimension of about 1000 mm and a storage capacity of 50 or more. The age structure of the monitor is: 1. 18 housewives in their 20s, 30s, and 40s ... 155cm tall, 155-1
60cm, 160-165cm each 6 2. 16-year-old housewife 60-70 years old ... average age 65.3 years 3. 7 young single women 19-19 years old ... average age 21.8 years old, loading shopping cart The goods are: 1. Housewives in their 20s and 40s ... 2 baskets on hand + 10kg of rice = 30kg gross weight 2. Elderly housewife, young single woman ... 2nd basket on hand
Only for individual = total weight 20kg.

As a result of the above test, the running speed was 20m / min.
And 30m / min, almost the same evaluation was obtained. However, at a traveling speed of 20 m / min, opinions differed based on the difference in the inclination angles of both escalator devices. Table 1 shows the differences in opinion. In addition, since the results of the monitor test of the young single woman and the housewives in their 20s, 30s, and 40s were almost the same opinion,
In Table 1, housewives in their twenties, thirties, and forties were classified as other, together with young single women, and compared with elderly housewives.

As can be seen from the results in Table 1, the young single woman felt that the speed was slow even though he operated the shopping cart on the escalator device with an inclination angle of 20 °, and that even after getting on, the young single woman moved slowly. Many said that elderly housewives were slow to move after getting on. This is because the elderly housewife is operating the shopping cart at the time of boarding, so it is as hard as a general escalator device, and the attitude is stable after getting on, so it is said that it is late. It is thought that it was. A young single woman feels that 20 ° is slower at the same running speed at 20 ° and 30 °.

However, both young single women and elderly housewives were almost satisfied with the ease of boarding. In addition, elderly housewives are satisfied with the ease of getting off, but young single women are easy to get off regardless of the angle of inclination.

In addition, overall results were almost favorable for elderly housewives, excluding dissatisfaction with boarding speed and moving speed.

As a result of partial improvement based on the above monitor test, the inclination angle is 15 to 25 ゜, the traveling speed is 15 to 25m / min, the number of horizontal steps in the lower horizontal section is 3 or more, and the length of the concave curve section is 1221 mm
The radius of curvature of the above or three steps or the concave curve section is
It turned out that the shopping cart can be safely transported with the escalator device even for the elderly, 2500-3500mm.
