Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to elevators for private residences that require space saving and low cost, and particularly relates to safety elevators related to landing doors, car doors, inner walls of hoistways, etc. Regarding structures suitable for sex.

[Conventional technology]

In conventional passenger elevators, Utility Model 60-170380
No., JP-A-51-93041, JP-A-52-1065
As stated in Publication No. 40, the vertical surfaces of the back surfaces of the landing door and the car door are set back from the front end surfaces of the sills that guide the doors, and the back surface of the first landing door protrudes from the inner wall of the hoistway. The elevator, landing door rail, and door lock device are installed so as to protrude from the inner wall surface of the hoistway.

Furthermore, both the landing door and the car door are often two or more sliding doors, and most of them are opened and closed by a door opening/closing device using an electric motor or the like.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, due to the emphasis on public service, the time required to open and close the car door and landing door is generally shortened as much as possible, and quiet operation is required, so door opening/closing devices using electric motors etc. Since the car door and the landing door are opened and closed at the same time, it is usually difficult to arbitrarily change the time period for opening and closing the door at any time, and there is a risk that people or other objects entering and exiting the car may come into contact with or get caught in the door. There is.

In addition, the gap between the landing door and the car door, and the area from the car doorway to the inner wall of the hoistway, have the structure of the prior art, and
If these dimensions are applied, the space will be quite large, and there is a risk that pets and other small animals may enter.

An object of the present invention is to reduce this risk rationally and economically, and to provide a safe and highly reliable elevator.

[Means to solve the problem]

The above purpose is to use manual opening/closing for the landing door and the car door, to use flush doors with flat front and back surfaces for both doors, and to make the back surface of both the shutters almost flush with the edge of each sill (floor). This is achieved by using a single door, making the back surface of the first landing door and the inner wall of the hoistway substantially the same plane, and incorporating the landing door rail and door lock device into the hoistway wall.

(Function) Manually opening and closing the landing door and car door eliminates the need for a door opening/closing device using an electric motor, which saves space and reduces costs; however, the door opening/closing system that occurs when using a door opening/closing device There is no time limit and the door can be opened and closed freely, reducing the risk of people or other objects coming in and out of the car touching or getting caught in the door. Both are flat flush doors, making it difficult for solid objects to be drawn in or scratched if they come into contact with the door.

If the back surfaces of both shutters are moved forward until they are almost flush with the edge of each sill (floor), the distance between the two doors becomes smaller, making it difficult for solid objects such as small animals to enter.

No matter how many car doors there are, if there is only one landing door (sliding door), the space between the car door and the landing door will be narrower than if there are multiple doors. This makes it difficult for solid objects such as small animals inside the car to enter when the car door is opened while the landing door is closed.

When the back surface of the landing door and the inner wall surface of the hoistway are made almost on the same plane, the distance from the car entrance/exit part to the inner wall surface of the hoistway becomes small, making it difficult for solid objects such as small animals to enter.

When the landing door rail and the door lock device are built into the hoistway wall, the distance from the entrance/exit part of the first car to the inner wall of the hoistway becomes smaller, making it difficult for solid objects such as small animals to enter.

As a result, elevator safety is improved.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 5.

The building 1 has a hoistway 2, and the hoistway 2 includes a landing door 3, a hoistway wall 4, a building floor 5, a steel tower 6, and the like.

There is a drive device 7 at the top of the steel tower 6, and a ride lever 9 is attached to one end of a hanging cable 8 wrapped around the drive device 7.
A counterweight 10 is attached to the other end, and the ride weight 9 and counterweight 10 are raised and lowered by a drive device E7.

The car 9 includes a car door 11, a first car door 12, a second car door 13, and the like.

The landing door 3 is a flat flush door on both the front surface 3' and the back surface 31, and the back surface 3# is the building floor end 14 and the hoistway inner wall surface 1.
It is formed into a single sliding door located almost on the same plane as 5.

With the invention that comprehensively combines not only the back surface 3'' of the landing door 3, but also the building floor end 14 and the hoistway inner wall surface 15, the two surfaces are almost on the same surface.

The basic configuration such as the cross-sectional shape of the car door 12 and the car door 13 and the properties of the front and back surfaces are the same as the landing door 3.

A back surface 12' of the car door 12 is formed to be substantially flush with the car floor end 16.

The landing door 3 and the car door 12, 13 are configured to be opened and closed manually without using a door opening/closing device using an electric motor or the like.

The landing door 3 is provided with a hanging roller 17 and a door hook 18, and the hoistway wall 4 above the landing door 3 has a landing door rail 19.
A door hook 18 is provided at the closed end of the first landing door 3.
A hook 20 and a switch 21 are attached to the hoistway wall 4 at the same height as
, a door lock device equipped with an engagement roller 22, an arm 23, etc.! 24 are provided.

The landing door 3 is suspended from the hanging roller 17, and the landing door rail 19
, the door hook 18 engages with the hook 20 of the door lock device 24 and activates the switch 21, and the engagement piece 25 provided on the door handle 9 rotates the engagement roller 22 clockwise. When pressed, the switch 21 is shut off, the hook 20 is released from the door hook 18, and the landing door 3 is opened.

Here, the engagement roller 22 that engages with the engagement piece 25 provided on the ride 9 that ascends and descends within the hoistway 2, and a portion of the arm 23 protrude into the hoistway 2, but the hook 20, Most of the door lock device 24 including the switch 21 and the landing door rail 19 are built into the hoistway wall 4.

Further, the planar positions of the engagement roller 22 and the arm 23 in the hoistway 2 are outside the car outline on the closed end side of the door, and
The car contour line along the entrance/exit direction is moved closer to the hoistway wall, so there is no problem in bringing the car 9 closer to the landing door 3.

According to this embodiment, the opening/closing times of the landing door 31, the car door 12, and the car door 13 can be freely selected, so that one person or other solid objects entering and exiting the car door 9 may come into contact with or get caught in the three types of doors. Furthermore, by making the front and back surfaces of the three types of doors flat flush doors, even if solid objects come into contact with the doors, they are less likely to be drawn in or get scratched.

Furthermore, the car 9 is inserted into the gap between the building floor end 14 and the car floor end 16.
If the dimensions are calculated by adding a slight margin to the swaying during lifting and lowering of the car and the dimensional differences in the manufacturing of the equipment, then the gap between the two floors, the landing door 3, the car door, and the car door. Since the gaps between the hoistway inner wall surface 15 and the car door 12, the car door 13, and the car door 9 become smaller, it becomes difficult for solid objects such as small animals to enter these gaps.

If the landing door 3 is a single sliding door, the space between the landing door and the car door will be narrower than if it is made up of multiple doors. This makes it difficult for solid objects such as small animals inside the car to enter when the door is opened.

According to this embodiment, the car door is a two-piece sliding door system consisting of the car door 12 and the car door 13, but the car door 3
Similarly, since the same inventive effect can be obtained using a single sliding door, it is also included in the scope of the present invention.

[Effects of the Invention] According to the present invention, the safety of the elevator is improved because it is possible to prevent entry and falling by reducing the gap around the elevator entrance and exit, and to reduce the chance of being caught or touched by the door by freely selecting the door opening/closing time. will improve.
