Generally, the escalator apparatus is provided over the upper floor side and the lower floor side, for example as described in Unexamined-Japanese-Patent No. 4-133993, and rotates the several stairs connected steplessly between the upper and lower lifting floors. have.

The escalator apparatus of the said structure is provided for the use of a general passenger, and the movement to other floors of a carriage, such as a shopping cart, is performed only using the electric road of a gentle slope. However, in the electric road, the inclination angle cannot be large, so there is a problem that a large installation area is required, and there is a problem that the vehicle must be supported in an unstable posture because the stepped surface is continuously inclined.

(Initiation of invention)

One object of the present invention is to provide an escalator apparatus in which a carriage can be mounted.

Another object of the present invention is to provide an escalator device that is easy and safe to get on a carriage.

In order to achieve the above object, the present invention is to provide a frame provided on the upper layer side and the lower layer side, a traveling path consisting of an upper horizontal section, a convex curve section, an inclined section, a concave curved section, a lower horizontal section, In the escalator device formed by circular movement of a plurality of steps connected steplessly along the running path, three or more steps are always configured to run each of the lower horizontal section and the concave curve section.

In the case of using a carriage in an escalator device, problems such as mobility from the horizontal section to the lifting floor, change in the moving direction between the horizontal section and the curved section, etc. are problematic. Since there is always a wide horizontal plane, it is easy to get on the carriage, and the curvature radius of the three-step curvature is always increased. Handling becomes easy, and a carriage can be mounted in an escalator apparatus by this.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 6.

Generally, the escalator apparatus is comprised as follows. That is, the upper raised floor 4 and the lower raised floor 5 are provided at both ends in the longitudinal direction of the main body frame 3 provided over the upper layer 1 and the lower layer 2, and these raised floors 4, 5) The several steps 6 connected by the stepless chain of steps | steps are rotated between them. Each staircase 6 forms the step surface 6S which has a depth dimension of 400 mm front and back normally. These staircases 6 are provided with the front wheel 8 and the rear wheel 9, respectively, so as to be circulated and guided along the paths and the return paths formed by the guide rails 7A and 7B provided in the frame 3, respectively.

The guide rails 7A and 7B have an upper horizontal section A adjacent to the upper elevating floor 4, a convex curved section B connected to the upper horizontal section A, and an inclined section connected to the convex curved section B on the path side. C, a concave curved section D connected to the inclined section C, and a lower horizontal section E connected to the concave curved section D and adjacent to the lower raised floor 5.

Moreover, along the traveling direction of the staircase 6, the handrail panel 10 vertically installed on the frame 3 is located on both sides thereof and moves in synchronization with the staircase 6 along the periphery of the handrail panel 10. The moving handrail 11 to be guided is supported.

In the above-described configuration, in consideration of the mounting of the carriage, in this embodiment, as shown in Fig. 3, the cleats of the stairs 6 are provided at the distal end portions of the elevating ridges 4 and 5. A concave curved surface 12S is formed on the upper surface of the comb-like member 12 having a comb-shaped tooth meshing with 6C). The concave curved surface 12S is formed on the upper surface from the distal end of the comb-shaped tooth to the vicinity of the attachment portion to both the raised floors 4 and 5.

Moreover, a concave curved section D inside the upper horizontal section A from the comb shaped member 12 of the upper raised floor 4 to the convex curved section B and from the comb shaped member 12 of the lower raised floor 5. In the lower horizontal section E up to three stairs 6 are connected to each other so as to form a horizontal plane and to travel. Therefore, a horizontal plane having a depth dimension (length of the scaffold moving direction) of 1200 mm is always present 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 staircases 6 are configured to travel with a step smaller than the step in the inclined section C. .

Next, the operation in the case of moving the shopping cart 14 which is a transportation vehicle from the lower layer 2 to the upper layer 1 by the escalator apparatus of the said structure is demonstrated.

The shopping cart 14 includes an accommodating part 15 for storing a shopping object or a shopping basket, and a front wheel l6 and a rear wheel l7 for supporting the accommodating part 15 and having an interval of about 1000 mm. It consists of a trolley | bogie 18 and the handle part 19, and a user generally determines the advancing direction of the shopping cart 14 by pressing the handle part l9 with the storage part l5 to the front side. Doing. The front wheel 16 and the rear wheel 17 are made of a material wheel which can be easily changed in direction by a user's operation.

When the shopping cart 14 is burned on an escalator device, as shown in FIG. 4, the shopping cart 14 is moved from the lower lifting floor 5 to the step 6 during movement. If the moving speed of the shopping cart 14 at this time is synchronized with the moving speed of the stairs 6, the shopping cart 14 can be stably moved above the stairs 6 without any problem.

When the shopping cart 14 is climbed at a speed slower than the moving speed of the stairs 6, the direction of the front wheel 16 changes 180 degrees as indicated by the two-dot chain line in FIG. The shopping cart 14 is shaken, but the user is not shaken by the shopping cart 14 because it is a momentary work.

When the shopping cart 14 is climbed at a speed faster than the moving speed of the stairs 6, it is possible to climb in the state shown in FIG.

After the front wheel 16 and the rear wheel 17 of the shopping cart 14 have climbed on the stairs 6, the user climbs on the stairs 6 on the lower side in accordance with the moving speed of the stairs 6, It is only necessary to hold the handle part 19 of the shopping cart 14 and stop. In the shopping cart 14, the front wheel 16 enters the concave curved section D at the moment when the passenger climbs and the front is lifted. However, the concave curved section D has three staircases 6 having a depth of 400 mm. Since the radius is 2500-3500 mm and the curvature has a gentle curvature, the forward lifting is performed smoothly, so that the user does not have to collapse the posture.

As the staircase 6 runs, the shopping cart 14 is transported from the concave curved section D to the inclined section C as shown in FIG. 5. In the inclined section C, since the front wheel 16 is lifted higher than the rear wheel 17 in the shopping cart 14, the force that the shopping cart 14 tries to move in the downward direction of the inclination acts, but the force Is weak, and because it is received by the horizontal step surface 6S of the staircase 6, the user can press it without requiring such a great force.

When the run of the stairs 6 advances and the front wheel 16 of the shopping cart 14 enters the convex curve section B, since this convex curve section B also becomes large curvature, the shopping cart 14 is gentle. The attitude is returned to the horizontal position in the upper horizontal section A. The front wheel 16 hits the comb-shaped member 12 at the tip of the upper lifting ridge 4 not far from the upper horizontal section A, but at this time, the comb engaging the cleat 6C of the staircase 6. Since the concave curved surface 12S is formed on the upper surface of the member 12 in the form, the front wheel 16 can be smoothly climbed on the upper lifting floor 4 by the inertia of the shopping cart 14, and the elderly There is no shock when we get on, and it is safe. On the other hand, since the upper surface of the comb-shaped teeth 12S is formed in the convex surface m as shown by the dashed-dotted line of FIG. 6, the conventional comb-shaped member 12 is n compared with the concave curved surface 12S. When the front wheel 16 collides, the repulsive force is transmitted to the user, and the user needs to push the shopping cart 14 with a force higher than the repulsive force, but the repelling force is such that there is no problem for the young housewife.

The above is description of the case where the shopping cart 14 is moved from the lower layer 2 to the upper layer 1, but when the shopping cart 14 is moved from the upper layer 1 to the lower layer 2, the above operation is performed. The shopping cart 14 may be moved in the reverse order.

That is, by pressing the handle portion l9 on the upper lifting floor 4 to the front side to advance the shopping cart 14, the three adjacent stairs that are horizontally arranged in the upper horizontal section A ( The front wheel 16 and the rear wheel 17 are moved on the step surface 6S of 6), and the user also climbs on the staircase 6 on the rear side and stops. If it obeys the operation of the escalator apparatus in this state, the shopping cart 14 will incline gently forward in the convex curve section B, and will enter the inclined section C as it is. Although the state passes through the inclined section C and enters the concave curved section D in this state, as shown in FIG. Since the part 19 also changes smoothly according to the radius of curvature, as shown from the a position to the b position, the user can be relieved. The shopping cart 14 held completely horizontal at the lower lifting floor E hits the front wheel 16 against the toothed end of the comb-shaped member 12 at the tip of the lower lifting floor 5, but at this time, Since the shopping cart 14 has inertia, the shopping cart 14 can be easily moved to the lower lifting floor 5.

As described above, according to the present embodiment, three staircases 6 are configured to always run continuously in the upper horizontal section A, the lower horizontal section E, and the convex curve section B and the concave curve section D connected thereto. Since the shopping cart 14 can easily get on and off the stairs 6 and the radius of curvature of the concave convex curve section is increased, the change of the direction between the upper horizontal section A, the lower horizontal section E and the inclined section C is made. When the shopping cart 14 becomes smooth, a large repulsive force due to a sudden change in direction is not transmitted to the user.

By the way, as shown in FIG. 5, the mutual step hb of the group of stairs 6 of the inclination section C which is the longest stairs running path of the escalator apparatus which concerns on this embodiment is less than l / 2.5 of the stairs depth dimension, Moreover, it is set so that it may become more than the diameter of the front wheel 16 of the shopping cart l4. This step hb becomes 160 mm or less when the depth dimension of the staircase 6 is 400 mm, and becomes almost the same height as the staircase of a normal house (same as the height of the height of the building standard method), and is used in a familiar posture. At the same time, even in the ascending direction, even if the passenger pushes the shopping cart 14 wrongly and strongly, the front wheel 16 serves as a stopper without passing over the step hb.

As shown in Fig. 7, the step generated in the lower horizontal section E and the concave curved section D is considered to correct the attitude of the shopping cart 14 that has descended. That is, the small step ha between the lower horizontal section E and the stairway 6 located adjacent to the concave curved section D is set to, for example, 30 mm or less below the radius of the rear wheel 17 of the shopping cart 14. When the shopping cart 14 that has advanced toward the lower lift floor 5 is oblique to the traveling direction, the rear wheel 17 is pulled out when the shopping cart 14 is pulled backward to fix it. It is easily dimensioned beyond the small step ha. If the size of this small step ha is set to the height dimension of the caution belt colored on the top of the stair riser, as shown in the dashed-dotted line 16 'of FIG. 4, the user who presses the shopping cart 14 and climbs upwards In addition, since the front wheel 16 of the shopping cart 14 can be stopped by hitting a small step ha, the shopping cart 14 can be stopped at the correct lift position, and the slipping accident can be prevented.

Moreover, as shown in FIG. 2, the length L from the tip of the comb-shaped member 12 which is the pull-out dimension to the stepped side of the handrail 10 to the handrail end is the front wheel 16 of the shopping cart 14. On the contrary, when the passenger's posture becomes unstable when the shopping cart 14 is set on the stairway 6 when the shopping cart 14 is set above the interval between the rear wheel 17 and the rear wheel 17, the moving handrail 11 can be lifted. Since the moving handrail 1l can be removed even when descending from the staircase 6 to the raised floors 4 and 5, it also contributes greatly in securing safety.

In addition, as shown in Fig. 8, when the guide rails 7A and 7B of the lower horizontal section E are configured to be inclined at the θ angle, for example, 1 to 5 degrees, to descend to the lower lifting floor 5, three steps A continuous plane inclined downward by (6) is formed, and proceeds toward the inclination of the upward direction with respect to the shopping cart 14 and its user who climb from the lower hoistway 5 to the stairs 6. It is to inform them in advance and to make mental preparations. On the other hand, it is easy for the descending passenger to descend using the heavy moving force toward the comb-shaped member 12 of the shopping cart 14 caused by the inclination angle. Furthermore, by inclining the lower horizontal section E, the movement to the adjacent concave curved section D can be made more gentle.

Each embodiment described above,

a. Horizontal section over 1200mm in length

b. Front and rear wheel gap of shopping cart less than 1000mm

c. 1200mm or more in length of concave convex curve

d. Escalator installation angle around 20 °

e. Radius of curvature of concave convex curve section 2500 ~ 3500mm

Is most preferred and these are based on the verification of the monitor test.

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

An internal escalator device in accordance with the Building Standards Act and an escalator device according to the present embodiment were installed inside the factory.

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

The escalator apparatus according to the present embodiment has an inclination angle of 20 °, three steps of the step surface of the lower horizontal section, and a concave curved section having a radius of curvature of 2500 mm and a length of 872 mm.

In addition, the depth dimension of the step surface of the stairs of both escalator apparatuses was 400 mm, and it tested at the traveling speed of 20 m / min and 30 m / min. As shopping carts used, three shopping carts were used whose front wheel and rear wheel shaft dimensions were about l000 mm and had a storage capacity of 50 l or more. The age configuration of the monitor,

l. 18 housewives in their 20s, 30s and 40s

… 6 people under 155cm tall, 155 ~ 160cm, 160 ~ 165cm

2. 16 elderly housewives aged 60 to 70

… Average age 65.3 years

3. Seven young single women aged 19 to 23

… Average age 2l.8 years

Is,

The loading product of the shopping cart,

l. Housewives in their 20s and 40s. 2 portable market baskets + 10kg rice = 30kg gross weight

2. Elderly housewives, young single women… Only 2 portable shopping baskets as above = Gross weight 20kg

It was made.

As a result of the monitor test in the above-mentioned content, about the same evaluation was acquired about 20 m / min and 30 m / min. However, opinions were divided from the difference in the inclination angles of the two escalator devices at the traveling speed of 20 m / min. This disagreement is shown in Table 1. On the other hand, since the results of the monitor test of young single women and housewives in their 20s, 30s and 40s were almost the same opinion, Table 1 shows that the housewives in their 20s, 30s and 40s were separated from young single women. And elderly housewives.

As can be seen from the results in Table 1, many young single women feel that the speed is slow even though they operate a shopping cart on an escalator device with an inclination angle of 20 °, and there are many opinions that movement is slow even after getting on. There were many opinions that elderly people housewives said that movement after getting on was slow. It is thought that this is because the elderly housewives operate the shopping carts at the time of getting on, so they suffer as in the case of general escalator devices, and because the posture is stable, they are slow. In addition, young single women feel slower at 20 ° at inclination angles of 20 ° and 30 ° even at the same traveling speed.

However, both young single women and elderly housewives showed almost satisfactory results for easy riding. In addition, elderly housewives were satisfied with regard to ease of falling, but young single women were likely to fall regardless of the angle of inclination.

In addition, almost all of the elderly had a favorable result except the discomfort of the riding speed and the moving speed for the housewives.

Based on the above monitor test, some improvements were made. The angle of inclination was 15 ° to 25 °, the driving speed was 15 to 25 m / min, the number of steps in the lower horizontal section was 3 or more, the length of the concave curve section was 1221 mm or more, or The curvature radius of the three or concave curved sections was 2500 to 3500 mm, and it was found that even an elderly person can safely transport a shopping cart with an escalator device.
