Description

  The present invention relates to an elevator apparatus. More specifically, since it is a device that can move in directions other than vertical, it should be an elevator-like device, but it can be said that it is an elevator device field from the viewpoint that the elevator car can also move in the vertical direction.

Elevator equipment is very useful for moving people and goods in environments with different elevations, and as the use of living space becomes multi-layered, it becomes an indispensable means of transport and transportation for daily life and economic activities. ing. In most of the conventional elevator apparatuses, an elevator car moves in the vertical direction and conveys people and things.

Since the direction in which movement or transportation is desired is not limited to the vertical direction, when the vehicle is to be moved in an oblique direction, a skewed elevator in which the moving path of the car is obliquely used is used. This skewed elevator is different from a normal elevator in that the moving path of the elevator car is provided obliquely, but basically there is no significant difference from a normal elevator, and the car is kept in a horizontal position while keeping the floor of the car almost horizontal. It can move with a substantially constant inclination in the vertical direction with a horizontal component.

  However, there are many cases where the requirements cannot be satisfied simply by being easily transported in a vertical or oblique direction, such as moving passengers from one platform to another in a station. Elevator-like devices that can move laterally in addition to direction are desired. In order to satisfy such a requirement, there has been proposed a connecting bridge elevator operating device of Patent Document 1 in which an elevator moving in the vertical direction is combined with a horizontally moving car. In the following text, the term elevator device is used to include an elevator-like device unless there is a particular need for distinction.

The above-mentioned elevator operation system for connecting bridges is a combination of a conventional elevator installed on each platform that can move in the vertical direction and a horizontally moving car, so it can move not only in the vertical direction but also in the horizontal direction on the car. It is groundbreaking in terms of what it can do. However, the elevator operation device for connecting bridges of Patent Document 1 is not capable of reaching the destination point with a single operation like a normal elevator when moving from one platform to another. There is an inconvenience because it is necessary to change the car at a point where the direction of the road changes, and time adjustment and driving operation are necessary for each change, especially those who are said to be elderly or weak who need an elevator for the connecting bridge For us, it was not always easy to use. For elderly people and those with weak legs, wide roads with multiple lanes and railroad crossings with many rails are very dangerous because it takes a long time to cross. It was necessary to ensure safe and smooth traffic for pedestrians.

Or an elevator device.

Since the present invention can move without changing to a direction other than the vertical direction including the vertical direction with a single simple driving operation, the complexity of transfer and the waiting time of the car are unnecessary, so that the target point can be safely and quickly. An elevator device that can be reached is realized. The elevator apparatus according to the present invention can reach a destination via a vertical movement path or a horizontal movement path when the user gets into the car at the starting point and instructs the destination to operate a normal elevator, for example. Is. It is possible to get on and off at an intermediate point by providing a stop point as appropriate between the starting point and the farthest point. In addition, by installing the elevator apparatus of the present invention on a wide road composed of a plurality of lanes or a railway crossing with a large number of rails, a pedestrian can pass safely and smoothly.

The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an elevator apparatus 1 according to the present invention. The figure is a side view of the car 2 in the moving path room, and the moving path room itself is not drawn. On both sides of the figure, there is a vertical movement path 3 in which the car 2 of the elevator apparatus 1 moves vertically, and in the center of the figure is a horizontal movement path 4 in which the car 2 moves in the horizontal direction.

In the elevator apparatus 1 of the present invention, one car 2 is provided for each moving path room. Here, a plurality of cars 2 are described for explaining the movement of the car 2. In addition, when explaining the movement of the elevator apparatus 1, unless otherwise specified in the following sentence, a description will be given on a route where the car 2 reaches the lower left position starting from the lower right position. There is no obstacle. Furthermore, the horizontal cross section of the car 2 may be a complicated shape such as a circle or a polygon, but here it will be described as a square.

As described above, a plurality of cars are shown in the figure, but one car 2 is placed in the moving path room, and each of the outer side surfaces 5 facing each other (the side appearing as the front in the figure and the opposite side). At least three guide rollers 6 are rotatably attached so that each shaft is orthogonal to the outer surface 5 of the car 2. At this time, if the distance between the guide rollers 6 is set as large as possible, the stability of the car 2 moving in the movement path chamber increases. However, in the case of FIG. One guide roller 6 is provided in the vicinity.

On both sides of the figure, there is a vertical movement path 3 in which the car 2 of the elevator apparatus 1 moves vertically, and in the center of the figure is a horizontal movement path 4 in which the car 2 moves in the horizontal direction. A guide way 7 for guiding the guide roller 6 is provided for each guide roller 6 on the inner surface of the movement path chamber. The guide way 7 is attached in the vertical direction in the vertical movement portion and in the horizontal direction in the horizontal movement portion. Where the value changes, a roundness is provided to change it gently. Further, the guide way 7 for each guide roller 6 may be shared in a portion where the trajectory of the guide roller 6 overlaps like the guide way 7 provided in the horizontal movement path 4 in the figure.

In the elevator apparatus 1 of FIG. 1, when the guide way 7 for each guide roller 6 is mounted in the moving path room, two of the lower car guide rollers 6 are moved closer to the car 2 than the guide roller 6 near the upper center of the car 2. To prevent the guideways 7 from interfering with each other. FIG. 17 is a perspective view of the portion 12 where the guideway 7 of FIG. 1 intersects as viewed from the inside of the moving path opposite to FIG. The guide way 7 for the guide roller 6 at the lower part of the car is attached to the car on the inner wall of the moving path, and the guide way 7 for the guide roller 6 at the center of the upper part of the car is attached at a position away from the car 2 on the inner wall of the moving path. At a location 12 where the guide way 7 for the lower car guide roller 6 and the guide way 7 for the upper guide car 6 at the center of the car intersect, the upper car center guide roller 6 that moves as the car 2 moves is the lower guide car roller. 6, the guide way 7 for the car lower guide roller 6 is cut out by a dimension slightly larger than the diameter of the guide roller 6 to provide a notch 13 for the guide roller 6 at the center of the upper part of the car.
