Abstract

(57) [Abstract] [Purpose] To provide an open state holding device for an elevator hall door with a simple structure and good operability. A key hook 5A is attached to one of the surface of the hall door 1 on the hoistway side and the sill 4, and an engaging pin 5B engaging with the key hook 5A is attached to the other.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for holding an open state of an elevator hall door.

[0002]

[Prior art]

 Conventionally, as a device for holding an elevator landing door in an open state, as described in Japanese Patent Application Laid-Open No. 61-127589, a pair of pressing pieces fitted in a sill groove and pressing an inner wall surface of the groove. The so-called Benri-Simari, which consists of butterfly bolts that move one of these pressing pieces, has been proposed. If you want to keep the landing doors open using the Beni Resimilar, while keeping the landing doors open, insert the pressure piece of the Beni Resimilar into the threshold groove and rotate the butterfly bolts to move the pressure pieces and press both sides. By pressing the both side walls of the sill groove with one piece, the Benri summary is fixed on the sill, and the landing door is prevented from closing. In other words, it keeps the landing door open.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional device can be mounted at any position and the opening degree of the landing door can be arbitrarily selected, but on the other hand, the butterfly bolt must be turned while maintaining the landing door open state, and the operability is not good. .

An object of the present invention is to provide an apparatus for holding an open state of a landing door, which has a simple structure and is excellent in operability.

[0005]

[Means for Solving the Problems]

 In order to achieve the above purpose, a hall door is provided at the boundary between the elevator hoistway and the halls on each floor, and an elevator equipped with a sill with a groove below the door to guide the travel of the door is provided. In a device for holding an open state of a landing door, a key hook is attached to one of the hoistway side surface of the landing door and the sill, and a locking pin that engages with the key hook is attached to the other, and the door is opened to open the key hook. The door is held in the open state by engaging with the locking pin.

[0006]

[Action]

 As described above, the structure is simple because it consists of the key hook and the locking pin, and when maintaining the open state of the landing door, the key hook may be engaged with the locking pin. To engage the key hook, all that is required is to rotate the key hook toward the locking pin, and therefore the operability is extremely good.

【Example】

 An embodiment in which the present invention is mounted on a central opening type landing door will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a front view showing an embodiment of a device for holding an open state of an elevator hall door as seen from inside the hoistway, and FIG. 2 is a plan view of the device for holding an open state.

In the figure, 1 is a hall door provided at the boundary between the hoistway 2 and each hall 3, and 4 is a sill provided at a position below the hall door 1 and having a groove 4 A for guiding traveling of the hall door 1. Reference numeral 5 denotes an open state holding device, and the hall door 1 is fully opened by the key hook 5A rotatably attached to the hoistway side surface of the hall door 1 and the side surface (or upper surface) of the sill 4. The lock pin 5B is attached at a position where it can be engaged with the key hook 5A.

When the hall door 1 is held in an open state, the door lock device (not shown, a device for preventing the hall door from being opened from the hall side) provided on the hall door 1 is pressed by a key. The landing door 1 is fully unlocked and the key hook 5A attached to the landing door 1 is rotated from the dotted line position to the solid line position in FIG. 1 to engage with the locking pin 5B. As a result, the landing door 1 is held in the open state.

When it is desired to release the holding of the opened state, the hall door 1 may be pressed and the key hook 5A may be turned in the opposite direction from the solid line position to the dotted line position.

[0012]

[Effect of device]

 As described above, according to the present invention, it is possible to improve workability with a simple structure and extremely excellent operability.
