Abstract

PURPOSE:To eliminate the occurrence of the gap or stage difference between a cage and ride-station by providing the fack for integratedly moving a cage floor and cage chamber to a ride-station direction. CONSTITUTION:The gap and stage difference between a cage and ride-station is eliminated with a cage floor 3 and cage chamber 4 integratedly moved in the ride-station direction by the action of the jack 7 interposedly provided between a cage floor supporting frame 2 and the chamber 4. The error between cage and ride-station floors is absorbed and the sinking of the floor 3 prevented by moreover the mutual engagement between the taper-state projected part 9 formed at one side and the recessed part 11 formed at the another side of the cage sill 8 positioned at the end of the floor 3 and the ride-station sill 10 positioned at the end of the ride-station.

Description

[Detailed description of the invention] [Industrial application field]

This invention relates to a device that eliminates the gap that exists between the landings and four cabins of passenger cars, etc., when passengers get on and off.

[Conventional technology]

An elevator or dumbwaiter is a car that moves up and down along guide rails in a hoistway provided in a building. The driving force for raising and lowering the car is provided by a hoist that winds up the rope that hangs the car, or by a hydraulic device that pushes the car up. In order to ascend and descend, a gap necessarily exists between the cage and the hoistway wall. This gap also exists when the car lands on the landing. That is, as shown in FIG. 3, when the car room 4 landed on the landing 12, a gap existed between the car sill 8 and the landing sill 10. Recently, we have been trying to make this gap as small as possible, and even 0.
There is a demand for This is to prevent vibrations from occurring when a product that is sensitive to vibrations is transported and approaches this gap, or to prevent the cart carrying food from shaking and spilling the food. . Conventionally, in order to fill this gap, a device (Utility Model Publication No. 62-157
874 Fig. 3), ■ A device for passing the spanning board between the landing sill and the car sill on both sides of the gap, ■ A shape-memory alloy provided on the side of the car compartment that is heated by a heater to change its shape. A device that fills gaps using
874 (Fig. 1) etc. were proposed.

[Problem to be solved by the invention]

However, all of the above conventional devices are designed to fill the gap by moving moving members made of metal pieces, gang plates, and shape memory alloys from the car side to the landing side. There was a problem that a new gap was created between the sides, and a step was created between the spanning board and the 4 sides that housed the spanning board. (2) Furthermore, when there is a landing error in the vertical direction when the fourth chamber lands on the floor, there is also the problem that this landing error is not resolved in the conventional device and remains as it is. This problem (2) is especially problematic when the heel drive adjustment device is a hydraulic device and the heel floor sinks when the heel is on the floor for a long time. The invention of Party B was made to solve the above problems, and aims to provide a device that eliminates gaps and steps between the car and the landing, and at the same time does not cause vertical landing errors. do.

[Means to solve the problem]

This invention provides the following advantages:
A car floor support frame that is driven in the lifting direction in the hoistway, a car floor that is placed on this car floor support frame, and a car floor that is installed integrally with the car floor or installed on the car floor support frame or the car floor. , a roller that supports the car floor, and is arranged between the car floor support frame and the car compartment, one end of which is pin-coupled to the car floor support frame, and the other end pin-coupled to the back of the car floor, so that the car floor and the four compartments are connected in the direction of the landing. The jack is fitted into a tapered convex portion formed on either one of the car sill located at the end of the car floor and the landing sill located at the end of the landing, and the convex portion formed on the other. This is a car floor movable device equipped with a recessed portion. =3-

[For production]

Instead of simply moving the movable member to fill the gap as in the past, the car floor and the car room are moved together in the direction of the landing, so no new gap is created after the movable member moves. Also, there is no difference in level that occurs with conventional equipment that uses a spanning board. Furthermore, landing errors are absorbed by the function of the tapered convex part and the concave part that fits into the convex part, and even if the elevating drive device is a hydraulic device, because the convex part and the concave part fit together, it is possible to absorb landing errors. This prevents the floor from sinking.

【Example】

An embodiment of the invention of B will be explained with reference to FIGS. 1 and 2. FIG. 1 is a side view showing a state in which the elevator of this embodiment has landed on the floor. FIG. 2 is an enlarged view of the vicinity of the threshold in FIG. 1. In this elevator, a car frame 1 is suspended by a rope (not shown), and a car floor support frame 2 is provided horizontally at the lower side of the frame. Thereby, the car floor support frame 2 can be driven in the up-and-down direction within the hoistway. A car floor 3 is placed on the car floor support frame 2 of B. The side walls and ceiling of the car room 4 are integrally provided with the car floor 3. On the back side of the car floor 3, rollers 5 for supporting the car rest 3 are provided. The roller 5 (moves smoothly on the rail 6 provided on the car floor support frame 2). A protruding strip having a letter-shaped cross section is provided in the horizontal movement direction of the car floor.A groove having a T-shaped cross section for storing the protruding strip B is provided in the corresponding car floor 3 or car floor support frame 2. This stabilizes the car floor 3 with respect to the car floor support frame 2. Furthermore, a hydraulic jack 7 is arranged between the car floor 3 and the car floor support frame 2. One end of the hydraulic jack 7 Kato floor 3
Pin 3a is connected to the other end, and pin 2a is connected to the car floor support frame 2 at the other end.
be combined. The arrangement direction of the hydraulic jack 7 is the horizontal movement direction of the car floor, similar to the above-mentioned protrusion. A tapered convex portion 9 is formed in the car pavilion 8 located at the left end of the car floor 3 in the drawing toward the landing direction. A recess 1 having a shape that fits into the projection is formed in the landing sill 10 at a position corresponding to the projection 9. The shapes of the convex portion 9 and the concave portion 11 are for absorbing landing errors. The operation of this embodiment will now be explained. After the elevator car has landed on the floor, the passenger operates an operation box (not shown) as necessary (7, activates the hydraulic jack 7. Through this operation, the car floor 3 and the car room 4 move together towards the landing. After the movement, the protrusion 9 of the car sill 8 fits into the recess 11 of the landing sill 10, and the gap that existed between the car 4 and the landing 12 disappears.The entire floor 3 moves again. Therefore, no new gaps or steps are created as in the conventional case.Furthermore, since the convex part 9 and the concave part 11 have a tapered shape, even if the landing error is Even if it is present, the landing error will not be absorbed during fitting due to the pressing force of the hydraulic jack 7.Furthermore, since the convex portion and the recessed portion are tightly fitted, heavy objects will not be loaded after landing. Or, even if you remain on the floor for a long time, the floor will not sink like in the conventional case.In addition, the above embodiment describes an elevator of the type that is suspended and driven by a rope. In other embodiments, it is possible to carry out the invention of B on the filter machine driven by a hydraulic system.In the above embodiments, the rollers 5 are provided on the side of the car body 3, but in other embodiments A roller may be provided on the side of the car support frame 2. [Effects of the Invention] As described above, according to the car floor moving device of the present invention, the car floor and the room can be integrally moved toward the landing side. Since the gap is eliminated, there is no need to create a new gap or step like in the conventional method.Furthermore, by fitting the tapered convex part and the concave part provided on the sill, it is possible to absorb and eliminate landing errors. .
