Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of a car of an oblique elevator that ascends and descends in a hoistway whose inclination angle changes.

[Conventional technology]

In order to accommodate the change in the inclination angle of the hoistway in a diagonal elevator, the car floor is made so that the floor surface is always kept horizontal.
It is equipped with the drive device shown in Japanese Patent No. 59-71257, and its structure is as shown in FIGS. 3 and 4. That is, in these figures, 1 is a car floor support, 2 is a car floor rotatably supported around a pin 3 attached to this car floor support 1, and 4 is a car floor that is always in a horizontal state. a drive device such as a piston, 5 is a car panel fixed to the car floor support 1, and a is a drive device such as a piston at both ends of the car floor 2 in the rotating direction and the bottom of the car panel 5. This is the gap between the car floor support 1 and the wall surface, and FIG. 4 shows a state in which the car floor support 1 is inclined.

As mentioned above, skewed elevators go up and down a hoistway where the inclination angle of the hoistway changes mid-way.In response to changes in the inclination angle of the hoistway, it is necessary to keep the floor surface of the car always level. A drive device as described above is provided to allow the car floor 2 to rotate.

Therefore, a considerable gap is provided between both ends of the car floor 2 in the rotating direction and the lower wall surface of the car panel.

[Problem that the invention attempts to solve]

Since the conventional oblique elevator is configured as described above, the gap a between the end of the car floor surface and the lower wall surface of the car room panel when the car floor 2 rotates is the fourth
1a and 2a as shown in the figure, this creates a risk that, for example, a passenger's feet may enter the wide gap, and foreign matter may fall into this gap, causing the car floor 2 to change. There were problems such as a negative effect on rotation. This invention aims to solve the above problems.

[Means for solving problems]

In the case of this invention, the lower wall portion 5 of the car room panel 5
a is bulged outward so as to match the rotational locus of both ends of the car floor 2 in the rotational direction, and a minimum gap b is always maintained between the car floor and the car floor. .

[Effect]

In the case of this device, safety is always ensured in the gap created between both ends of the car floor 2 in the rotation direction and the lower wall 5a of the car room panel 5, regardless of changes in the rotation angle of the car floor. be regulated to a minimum.

〔Example〕

An embodiment of this invention shown in FIGS. 1 and 2 will be described above. That is, the same parts in the figure as those in FIGS. 3 and 4 are indicated by the same reference numerals, but the lower wall part 5a of the car compartment panel 5 in this invention is in the direction of rotation of the rotating car floor 2. bulges outward so as to match the rotation locus at both ends of the car, and the gap b between the car floor and the car floor is set to the minimum necessary size that does not hinder the rotation of the car floor 2. This is a characteristic feature. That is, FIG. 2 shows a state in which the car floor 2 is rotated.

In the above-mentioned configuration, when the car floor support base 1 and the car floor 2 are kept parallel to each other, both ends of the car floor 2 in the rotation direction are in contact with the lower wall portion 5a of the car room panel 5.
However, when the car floor 2 is rotated by the drive unit 4 at a point where the inclination of the elevator shaft changes, both ends of the car floor 2 in the rotation direction move up and down along a rotational trajectory. On the other hand, the lower wall portion 5a of the car room panel 5 is previously caused to bulge outward so as to coincide with the above-mentioned rotational trajectory of the car floor 2, so that the dimension of the gap b between them is always maintained at a desired minimum constant value.

In the above embodiment, the lower wall portion 5 of the car compartment panel 5
a is formed into a bulge on a curved surface with a predetermined radius,
The bulge does not necessarily have to be a curved surface with a constant radius; for example, this portion may be a bulged curved surface divided into multiple stages by laminating baseboards or the like.

[Effect of idea]

Since this device is constructed as described above, even if the car floor is driven horizontally and both ends of the car draw a rotational trajectory, the gap between this and the lower wall of the car panel remains constant. This means that there is no risk of feet getting caught in the gap, and there is little chance of foreign matter getting into the gap, resulting in excellent safety and reliability. This has the effect of not damaging the aesthetic appearance of the bottom of the car room.

[Brief explanation of the drawing]

Figure 1 is a sectional view showing the interior of the cage of this invention.
FIG. 2 is a similar sectional view showing the operating state of the car floor, FIG. 3 is a sectional view showing the interior of the conventional car room, and FIG. 4 is a similar sectional view showing the operating state of the car floor. In the figure, 2 is the car floor, 5 is the car room panel, 5a
indicates the lower wall portion, and b indicates the gap. In other figures, the same reference numerals indicate the same parts.

Claims (1)

[Scope of utility model registration request] In an oblique elevator that moves up and down a hoistway with varying inclination angles, the lower wall of the car panel is moved outward so as to match the rotation locus at both ends of the car floor, which is constantly driven horizontally. A car for a diagonal elevator, characterized in that the car is bulged out and the gap between the car and the car floor is always kept to the minimum necessary.
