Description
The present invention relates to an emergency ladder, and more particularly to an emergency ladder for a stacked elevator that can be used by an official in an elevator cage in an emergency situation in an elevator.
Generally, an elevator facility is a moving means for carrying passengers or cargo in a cage along a hoistway formed vertically inside the building structure to carry the interlayer.
Such an elevator moves along a hoistway formed in a rectangular parallelepiped shape. In each floor of the building, an opening communicating with the hoistway is formed, and an elevator pit space is provided at the lowermost end of the hoistway.
The hoistway is provided with a cage on which objects or people ride, a rope which is additionally installed on the hoist for moving the cage, and a guide rail for guiding upward and downward movement of the hoist and the hoist, A door device is installed.
An elevator structure installed inside the elevator pit for installing the elevator has a scaffold in which a plurality of vertical rods and horizontal rods are coupled from the lower part to the upper part of the elevator pit and then the scaffold is joined to the scaffold, An elevator structure is constructed by fastening a steel bar supplied from the outside to an elevator pit with an anchor bolt.
FIG. 1 is a perspective view showing a conventional side wall assembly structure of an elevator cage according to a Korean Utility Model Application No. 20-1997-003703.
1, when a plurality of
The cage is provided with a slat bottom, a control panel is installed on one side of the elevator door, and an emergency ladder is installed on the other side of the cage for fire suppression by the fire brigade .
However, the emergency ladder provided in the cage itself occupies a large volume, which is difficult to store in the cage, and the storage space for storing the emergency ladder takes up a large space according to the volume of the emergency ladder, .
Accordingly, the inventor of the present invention has proposed a technique for solving the above-mentioned problem, and proceeded with a patent application based on the technical content. (Korean Patent Application No. 10-2015-0077031 entitled "Folding emergency ladder provided in the elevator cage")
Such Korean Patent Application No. 10-2015-0077031 solves most of the problems of the conventional emergency ladder for an elevator, but it can be said that it is an early technology, and an improvement has occurred.
The conventional Korean Patent Application No. 10-2015-0077031 has a problem in that it is difficult to produce and assemble the product because of its complicated structure, and thus it takes a high production cost of the product.
In addition, in the conventional Korean patent application No. 10-2015-0077031, a pair of vertical frames can not realize a complete folding state during the folding process, which has a limitation in reducing the volume when the product is stored.
That is, in order to completely collapse the emergency ladder, all of the remaining components must be accommodated in a pair of vertical frames. However, the conventional emergency ladder is structured such that the hinge portion of the stiffening member protrudes outward and is accommodated in the pair of vertical frames I can not.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and its object is to provide an emergency ladder for an elevator that can accommodate other components in a pair of vertical frames during a folding process for storage, The present invention provides a foldable emergency ladder for a stacked type elevator capable of facilitating storage and improving space utilization inside the elevator.
Another object of the present invention is to provide a folding emergency ladder for a stacked type elevator which can minimize the components constituting the emergency ladder, thereby improving the productivity of the product and reducing the production cost of the product.
According to an aspect of the present invention, there is provided a ladder comprising: a plurality of ladder members folded in different directions; And a connecting hole provided on one of the plurality of ladder members for stacking and connecting the ladder members, wherein the ladder member comprises: a pair of vertical frames having receiving grooves therein; A plurality of kneading hinges hinged at regular intervals between the pair of vertical frames; And a detent protrusion formed at a lower end of the descending lever so as to be hinged to the inner wall of the vertical frame so as to be hinged only in one direction when the descending lever is horizontal.
In the present invention, the lifting frame may be configured to be received in a receiving groove formed in the pair of vertical frames during the folding process of the ladder member.
In the present invention, the connector is fixed to the ends of the pair of vertical frames, and is formed in a tubular shape opened to the space between the pair of vertical frames, and a locking protrusion may be provided at the open end.
