Description

The present invention relates to an elevator that balances the total weight of the cage (the sum of the cage's own weight and boarding load) and the balance weight, and moves up and down manually along a lifting rail.

Conventional elevators are lifted and lowered using a drive device such as an electric motor or a hydraulic pump.

It is difficult for people using wheelchairs or those who have weak legs to move between the upper and lower floors by stairs, and installing elevators is expensive and installing a power device for driving up and down Space is also needed.

Generally, people who need an elevator at home are specified, so that the total weight of the elevator cage (the sum of the weight of the cage and the onboard load) and the weight of the balance weight are almost balanced according to the usage status of the person. The weight of the balance weight is set, which reduces the lifting load of the elevator and eliminates the need for a lifting drive power device by operating manually, thereby solving the above problem by constructing an inexpensive and space-saving elevator. .

The elevator of the present invention is lower in installation cost than conventional ones and can be reduced in installation space, so that it can be easily introduced into ordinary households, and the convenience of movement between the upper and lower floors for wheelchair users and people with weak leg strength is enhanced.

The elevator's lifting load is reduced by making the elevator's total weight of the elevator (the sum of the cage's own weight and the boarding load) and the weight of the balance weight almost equal, and the lifting drive power unit is not required by operating manually.

As shown in FIG. 1, the elevator of the present invention connects a cage 1 and a balance weight 2 with a rope 5 via a pulley 3 and a pulley 4. The balance weight 2 is composed of a base weight and several adjustment weights, and the total weight is substantially balanced with the total weight of the cage (the sum of the weight of the cage 1 and the onboard load).

A driving method will be described. As shown in FIGS. 1 and 2, the handle 9 and the gear 11 are connected by the handle shaft 10, the gear 11 is engaged with the gear 12, and the gear 12 and the gear 13 are connected by the shaft 14. When the handle 9 is turned, the gear 11 rotates through the handle shaft 10, and the rotation of the gear 11 causes the rotation of the gear 12 and the gear 13. As shown in FIG. 11, the gear 13 moves up and down while rotating along the lifting rail 6, so that the cage 1 moves up and down while being guided by the guide rails 7 and 8. The gear 11 is smaller than the gear 12 so that the handle 9 can be rotated with a small force.

A reverse rotation preventing device as shown in FIG. The handle shaft 10 and the reverse rotation prevention gear 15 rotate as a unit. When the handle shaft 10 rotates (rises) in the direction A, the reverse rotation prevention gear 15 also rotates in the direction A. When the rotational force in the B direction is applied, the teeth of the reverse rotation prevention gear 15 hit the lowering prevention pin 17 and prevent reverse rotation (downward movement). When releasing the reverse rotation prevention, the lowering prevention pin 17 is turned to the position of the dotted line so as not to hit the reverse rotation prevention gear 15. In addition, the reverse rotation prevention gear 16 and the rise prevention pin 18 with this set turned upside down are also installed on the handle shaft 10 so that when rotating (lowering) in the B direction, the reverse rotation (upward) in the A direction is performed. Stop. Thereby, it is possible to prevent the reverse rotation even when the vehicle is raised and lowered.

FIG. 4 is a display example in the cage 1 of the reverse rotation prevention device, and the lowering prevention pin 17 and the raising prevention pin 18 are both in the prevention position (solid line circle), and are stopped without being raised or lowered. It is. When releasing the lowering prevention, the lowering prevention pin 17 is turned to the lowering position (dotted circle), and when raising prevention is released, the raising prevention pin 18 is turned to the rising position (dotted circle).

When the cage 1 is stopped on the lower floor 20 or the upper floor 21, the stop tweezers 32, 33 shown in FIG. , 34, 35. As shown in FIG. 5, the stop tweezer includes a stop pin case 22, a stop pin 23 and a spring 24, and a roller / ball 25 is attached to the tip of the stop pin 23. Normally, the stop pin 23 protrudes from the stop pin case 22 by the action of the spring 24.

A stop release device for releasing the stop state (protrusion state) of the stop pin 23 is installed on one surface of the cage 1 and its opposite surface. As shown in FIG. 6, the device raises the lock lever 28 upward (shown by a dotted line), pushes out the left and right unlocking rods 29, pushes the stop pin 23 into the stop pin case 22, and as shown in FIG. unlock. When the lock lever 28 is pushed down (shown by a solid line), the lock release rod 29 is pulled in, so that a space in which the stop pin 23 can be inserted is secured in the cage floor 19 as shown in FIG.

In order to prevent the cage 1 from being obstructed by the stop pin 23 when it is raised, the stop pin release horns 27 as shown in FIG. As the cage 1 rises, the roller / ball 25 rotates while contacting from the surface of the stop pin release horn 27 to the side surface of the cage 1 to make the cage 1 rise smoothly. Similarly, stop pin release horns 26 as shown in FIG. 10 are attached to the bottom of the cage 1 at four locations to allow the cage 1 to pass through when lowered.

A stopper 30 with a cushioning material is installed below the building floor so that the cage 1 does not descend any further under the cage 1 when the cage 1 is in the state shown in FIG. In addition, a stopper 31 with a cushioning material is installed on the ceiling of the building so that the cage 1 does not rise any further at a position above the cage 1 when the cage 1 rises to the upper floor and is in the state of FIG. Keep it.

The operation procedure of the elevator from where it got into the cage 1 on the lower floor is explained. As shown in FIG. 1, the lock lever 28 is installed at two locations facing each other. Stop tweezers are installed at four locations on each floor and operate at the four locations. In this description, the operation status at one location is shown below.

When getting into the cage 1 and raising it, the lock lever 28 shown in FIG. 6 is pulled up to extend the unlocking rod 29, and the stop pin 23 on the lower floor 21 is inserted into the stop pin case 22 as shown in FIG. 8. Push in. Next, the lift prevention pin 18 in the lift prevention position in FIG. 4 is turned to the lift position to release the lift prevention, and the handle 9 is turned upward to lift. When it is slightly lifted, the lock lever 28 is pushed down, and the unlocking rod 29 is retracted as shown in FIG.

When the cage 1 rises and the top reaches the upper floor 21, the stop pin release horn 27 rises while pushing the stop pin 23 against the spring 24 as shown in FIG. The floor 19 approaches the upper floor 21. Since the unlocking rod 29 is retracted when the position shown in FIG. 8 is reached, the stop pin 23 protrudes by the action of the spring 24 and holds the cage 1 as shown in FIG. You will arrive at the upper floor. In this state, for the sake of safety, the ascent prevention pin 18 of FIG.

When descending from the upper floor, the user gets into the cage 1 and pulls up the lock lever 28 of FIG. 6 to extend the unlocking rod 29 and push the stop pin 23 into the stop pin case 22 as shown in FIG. Next, the lowering prevention pin 17 located at the lowering prevention position in FIG. 4 is turned to the lowering position to release the lowering prevention, and the handle 9 is lowered in the lowering direction. When it is slightly lowered, the lock lever 28 is pushed down, and the lock release rod 29 is retracted.

When the cage 1 descends to the lower floor 20, the stop pin release horn 26 at the bottom of the cage 1 further descends while pushing the stop pin 23 against the spring 24 as shown in FIG. 10. When the position shown in FIG. 7 is reached, the stop pin 23 protrudes by the action of the spring 24 and holds the cage 1. This will arrive at the lower floor. In this state, for the sake of safety, the lowering prevention pin 17 is turned to the lowering prevention position, and it is confirmed that the ascent prevention pin 18 is at the ascent prevention position, and then gets off the cage 1.

Since the elevator of the present invention is driven by human power, it does not require a driving power unit and can be installed more easily than the conventional one.
