Description

  Embodiments of the present invention relate to a moving walkway.

  In various facilities such as airports and stations, moving walkways are used as one of the facilities for transporting users. These moving sidewalks are often driven at a moving speed of 30 to 40 m / min, and there is a problem that it takes time to carry the user at this moving speed.

  However, if the moving speed of the moving sidewalk is simply increased, a situation may occur in which the user loses balance and falls when the user gets on the moving sidewalk or gets off the moving sidewalk.

  Therefore, a variable-speed moving sidewalk has been proposed in which driving at a low speed on the entrance side and the exit side and driving at a high speed between the entrance side and the exit side (Patent Document 1, below). 2).

  The moving sidewalk described in Patent Document 1 has a low-speed moving sidewalk that moves at a low speed on the entrance side and the exit side, and a high speed that moves at a high speed between the entrance side and the exit side. There is a moving sidewalk. A user of a moving sidewalk gets on a moving sidewalk for low speed on the entrance side, transfers to a moving sidewalk for high speed on the way, and changes to a moving sidewalk for low speed on the exit side.

  The moving sidewalk described in Patent Document 2 is provided by placing a forward path and a return path adjacent to each other in the same horizontal plane, and overlapping the steps (pallets) positioned on the front and rear sides on the entrance side and the exit side. The movement speed between the mouth side and the exit side is made low, and the movement speed between the entrance side and the exit side where the steps do not overlap is made high.

Japanese Patent No. 3555753 Japanese Patent No. 4239382

  However, in the moving sidewalk described in Patent Document 1, it is necessary for the user to transfer from the moving sidewalk for low speed to the moving sidewalk for high speed, and from the moving sidewalk for high speed to the moving sidewalk for low speed. This is a burden on the user.

  In the moving sidewalk described in Patent Document 2, since the forward path and the return path are located side by side in adjacent positions in the horizontal plane, a large installation space is required to install this moving sidewalk. There are great restrictions on possible locations. Moreover, it is unsuitable for a place where the user wants to transport the user only in one direction.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a moving sidewalk that can safely convey a user at high speed without placing a burden on the user.

According to the embodiment, the moving sidewalk has a plurality of steps that circulate between the entrance side and the exit side in the same vertical plane, and the steps are formed in different shapes and follow the moving direction. The first step and the second step are alternately arranged such that the front end side and the rear end side are in contact with each other, and at least one of the first step and the second step is a direction along the moving direction of the step. The width dimension of the first step is different between the upper surface portion and the lower surface portion, and at least one of the first step and the second step is provided to be displaceable in the vertical direction between the entrance side and the exit side. The distance between the first step and the second step adjacent to each other is increased by relatively displacing the second step and the second step.

It is a perspective view which shows the 1st step and the 2nd step which are located in the entrance side. It is a side view which shows the state from which the space | interval of a 1st step and a 2nd step became wide between the entrance side and the exit side. The rear view which shows the positional relationship of the 1st step, the 2nd step, and a guide rail in case the upper surface part of a 1st step and the upper surface part of a 2nd step are located in the same height in the entrance side and the exit side. It is. The positional relationship between the first step, the second step, and the guide rail when there is a step between the upper surface of the first step and the upper surface of the second step between the entrance side and the exit side. FIG. It is a side view which shows the biasing body which connects 1st steps located on both sides of a 2nd step. It is a side view which shows the 1st step and 2nd step of other embodiment.

  An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the moving sidewalk includes a plurality of steps (a plurality of first steps) arranged so as to circulate between the entrance 1 side and the exit (not shown) side in the same vertical plane. 2a and a plurality of second steps 2b), a drive mechanism 3 for circulating and moving the steps 2a and 2b, and three types of six guide rails (first guide rail 4a and second guide) for guiding the circulating steps 2a and 2b. Guide rails 4b and 4c). The steps 2a and 2b are moving in the direction indicated by the arrow X from the entrance 1 side toward the exit side.

  On the entrance 1 side, there is provided a boarding board 5 that covers the drive mechanism 3 and the steps 2a, 2b where the moving direction is reversed, and is formed at the top of the board 2 at the top of the steps 2a, 2b. A comb 7 is provided for meshing with a cleat (not shown). The exit side is substantially the same as the entrance 1 side.

  As shown in FIG. 2, the first step 2a differs in the width dimension in the direction along the moving direction (arrow X direction) of the steps 2a and 2b between the upper surface portion 8 and the lower surface portion 9, and the width dimension of the upper surface portion 8. A side view shape with “A” being smaller than the width dimension “B” of the lower surface portion 9 is formed in a trapezoidal shape. The second step 2b also has a direction along the moving direction of the steps 2a and 2b, as shown in FIG. The width dimension is different between the upper surface part 10 and the lower surface part 11, and the side view shape in which the width dimension “C” of the upper surface part 10 is larger than the width dimension “D” of the lower surface part 11 is formed in a trapezoidal shape. The width dimension “A” of the upper surface portion 8 of the step 2a and the width dimension “D” of the lower surface portion 11 of the second step 2b may be the same or different, and the width dimension of the lower surface portion 9 of the first step 2a. “B” and the width dimension “C” of the upper surface portion 10 of the second step 2b may be the same as or different from each other. The upper surface portion 8 and the upper surface portion 10 of the second step 2b are portions on which a user transports his / her feet from the entrance 1 side toward the exit side, and the upper surface portion on the entrance 1 side and the exit side. 8 and the upper surface part 10 are located at the same height.

The first step 2a and the second step 2b are alternately arranged along the movement direction (arrow X direction), and the front end side along the movement direction and the rear end side along the movement direction are in contact with each other. Move while being maintained. Further, the front side surface portion 12 and the rear side surface portion 13 in the moving direction of the steps 2a and 2b are in surface contact with each other without a gap when the steps 2a and 2b are moving between the entrance side 1 and the exit side. It is an inclined surface.

  The drive mechanism 3 includes a motor 14, a drive wheel 16 that is rotationally driven by being connected to the motor 14 via a drive chain 15, and a drive gear 17 that is connected to the drive wheel 16 and rotates together with the drive wheel 16. I have. An engaging portion 18 is provided on the lower surface portion 9 of the first step 2a, and the driving force from the motor 14 is transmitted to the step 2a when the rotating drive gear 17 and the engaging portion 18 mesh with each other.

  The first guide rails 4a are a pair of guide rails for guiding the first step 2a, and are installed in a horizontal state between the entrance 1 side and the exit side as shown in FIG. Moreover, as shown in FIG. 4, a pair of 1st guide rail 4a is installed in parallel to the direction orthogonal to the moving direction of the 1st step 2a.

  A pair of front rollers 19 and rear rollers 20 are attached to the lower surface portion 9 of the first step 2a in the front-rear direction along the moving direction of the first step 2a. By rotating around the first guide rail 4a, the first step 2a moves on the first guide rail 4a. In addition, since the 1st step 2a moves on the 1st guide rail 4a installed in the horizontal state between the entrance 1 side and the exit side, between the entrance 1 side and the exit side It moves in the horizontal direction without being displaced in the vertical direction.

  The second guide rails 4b and 4c are two pairs of guide rails for guiding the second step 2b. As shown in FIGS. 3 and 4, the first guide rail is on the entrance 1 side (and the exit side). 4a and the height position in the vertical direction are the same, but between the entrance 1 side and the exit side, the first step 2a and the second step 2b are relatively relative to each other in the vertical direction as will be described later. In the displaced region, the second guide rails 4b and 4c are positioned below the first guide rail 4a.

  A pair of front rollers 21 and rear rollers 22 are attached to the lower surface portion 11 of the second step 2b in the front-rear direction along the moving direction of the second step 2b. The front roller 21 rotates with the second guide rail 4b interposed therebetween, and the rear roller 22 rotates with the second guide rail 4c interposed therebetween, whereby the second step 2b moves on the second guide rails 4b and 4c. Since the second step 2b moves on the second guide rails 4b and 4c located below the first guide rail 4a between the entrance 1 side and the exit side, the second step 2b Between the entrance 1 side and the exit side, the upper surface portion 10 moves in a state of being displaced to a position below the upper surface portion 8 of the first step 2a.

  Further, the second guide rail 4b and the second guide rail 4c are vertically moved in a partial section (section indicated by an arrow Y in FIG. 3) immediately after passing the entrance 1 side (and immediately before entering the exit). There is a step in the direction. This step is caused when the second step 2b is displaced downward after passing through the entrance 1 and when the second step 2b is displaced upward near the exit, the front roller 21 and the rear roller 22 are It is for maintaining the upper surface part 10 in a horizontal state by maintaining the same height position.

  A cutout portion 23 is formed at a location on both ends of the second step 2b in the direction orthogonal to the moving direction of the second step 2b and above the first guide rail 4a. Since the notch 23 is formed, as shown in FIG. 5, when the second step 2b is displaced to the lower position, the first guide rail 4a is located at the notch 23, and the second step 2b The step 2b is prevented from interfering with the first guide rail 4a.

As shown in FIG. 6, a biasing body 24 such as a tension spring that biases the first steps 2 a toward each other is connected between the first steps 2 a located between the second steps 2 b. ing. The urging body 24 is disposed at the notch 23 of the second step 2b so as not to interfere with the second step 2b when the second step 2b is displaced downward.

  FIG. 6A shows the steps 2a, 2b and the biasing body 24 located on the entrance 1 side (or the exit side), and the interval between the pair of first steps 2a is narrow, and the biasing body. 24 is in a contracted state. FIG. 6 (b) shows the steps 2a, 2b and the biasing body 24, which are located between the entrance 1 side and the exit side and are relatively displaced in the vertical direction. Since the interval between the steps 2a is wide, the urging body 24 is extended.

  In such a configuration, when driving on a moving sidewalk, the driving force from the motor 14 is transmitted to the first step 2 a positioned around the driving gear 17 via the driving gear 17. The second step 2b and the other first step 2a are sequentially pushed by the first step 2a to which the driving force is transmitted, and the steps 2a, 2b circulate on the guide rails 4a, 4b, 4c.

  Since the first guide rail 4a is installed horizontally from the entrance 1 side to the exit side, the first step 2a moving on the first guide rail 4a is from the entrance 1 side to the exit side. Move horizontally. On the other hand, since the second guide rails 4b and 4c are disposed below the first guide rail 4a between the entrance 1 side and the exit side, the second guide rails 4b and 4c move on the second guide rails 4b and 4c. The second step 2b moves downward after passing through the entrance 1 as shown in FIG. 3, and the first step 2a and the second step 2b are relatively displaced in the vertical direction.

  When the second step 2b is displaced downward, the first step 2a is pushed forward in the moving direction by the second step 2b, and the distance between the adjacent first step 2a and the second step 2b (adjacent to each other). The distance from the front end of the first step 2a to the rear end of the second step 2b is increased. Thereby, the moving speed of the moving sidewalk becomes faster than the entrance 1 side. On the exit side, the second step 2b that has been displaced downward is displaced upward, and the distance between the first step 2a and the second step 2b that are adjacent to each other is reduced, so that the moving speed of the moving sidewalk is reduced. Is slowed down.

  Therefore, it is possible to slow down the moving speed of the moving sidewalk at the entrance 1 side and the exit side, so that the user can get on and off safely, while the moving sidewalk moves between the entrance 1 side and the exit side. The user can be transported promptly by increasing the speed. In addition, since the acceleration and deceleration of the moving sidewalk are automatically performed, there is no burden on the user.

  Since the first step 2a and the second step 2b are formed in a trapezoidal shape when viewed from the side, when the first step 2a and the second step 2b are relatively displaced in the vertical direction, they become inclined surfaces. Slip occurs between the front side surface portion 12 and the rear side surface portion 13 that are present, and the distance between the first step 2a and the second step 2b is widened, and the moving speed of the moving sidewalk can be increased.

  In the portion where the moving speed of the sidewalk that moves between the entrance 1 side and the exit side is high, as shown in FIGS. 3 and 6 (b), the first step 2a and the second step 2b Steps are generated between them, and the user of the moving sidewalk can visually recognize the rear side surface portion 13 of the first step 2a located above the upper surface portion 10 of the second step 2b. Therefore, the rear side surface portion 13 of the first step 2a can be used as a medium for various advertisements, or the rear side surface portion 13 of the first step 2a is colored with a color that is easy to call attention (for example, yellow). By this, it is possible to alert the user to prevent tripping.

The first steps 2a located across the second step 2b are connected by an urging body 24 and are urged in a direction to attract each other. For this reason, the first step 2a and the second step 2b can always be kept in contact with the front end portion and the rear end portion in the moving direction by the biasing force of the biasing body 24, and the driving force from the motor 14 can be maintained. Even if it is the structure which transmits only to some 1st steps 2a located in the entrance 1 side, the movement of all the steps 2a and 2b can be performed smoothly.

  In the present embodiment, the case where the first step 2a and the second step 2b are trapezoidal in side view has been described as an example, but the shape of the first step 2a and the second step 2b is this shape. It is not limited to. For example, as shown in FIG. 7, the first step 31 a may be formed in a trapezoidal shape in a side view, and the second step 31 b may be formed in a T shape in a side view. In this case, if the second step 31b is displaced downward, the distance between the first step 31a and the second step 31b increases, and the moving speed of the moving sidewalk is increased between the entrance side and the exit side. Can be.

  In the present embodiment, the case where the moving speed of the moving sidewalk is increased by moving the second step 2b downward between the entrance 1 side and the exit side has been described as an example. The distance between the first step 2a and the second step 2b may be increased by moving the first step 2a upward, and the moving speed of the moving sidewalk may be increased.

  Moreover, regarding the attachment of the urging body 24, the second steps 2b positioned with the first step 2a interposed therebetween may be connected.

  According to the embodiment described above, the first step 2a and the second step 2b that are alternately arranged are relatively displaced in the vertical direction between the entrance 1 side and the exit side, and are positioned adjacent to each other. By widening the distance between the first step 2a and the second step 2b, the moving speed of the moving sidewalk is lowered at the entrance 1 side and the exit side, and between the entrance 1 side and the exit side The moving speed of the moving sidewalk can be increased. Thereby, it is possible to safely get on and off the moving sidewalk and to quickly transport the user.

  This embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
