Abstract

PURPOSE: To enhance the strength of a car frame having entrances in three directions by erecting corner columns in the adjacent corner part of a front side cargo entrance and left/right side entrances, arranging three erect columns in the inside parts of these corner columns and a rear side plate, and mutually connecting them to beam members on the upper/lower sides of a car. CONSTITUTION: Cargo entrances 20a to 20c are arranged in three directions on the front side and the left/right sides of a car room 20, and corner columns 23a, 23b are erected in the mutually adjacent corner parts. Three erect columns 22a to 22c are arranged in the inside part and the outside central part of a car room rear side plate 24 having no entrace, and are mutually connected to upper beam members 21a, 21b and a lower beam member to be formed as a car frame 30. The car frame 30 and the car room 20 are integrally formed. The strength of a car having cargo entrances in three directions can be enhanced by this constitution.

Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention] (Industrial Field of Application) The present invention relates to a car structure for a small elevator for luggage that has luggage entrances and exits in three directions: the front side, the left side, and the right side of the car room.

(Prior Art) In recent years, there have been many requests from customers for small elevators for luggage that can enter and exit luggage from three directions: the front side and both left and right sides of the car. A compact cargo elevator with this structure did not previously exist.

(Problem to be Solved by the Invention) By the way, the hoistway is provided with three-way entrances and exits, and in correspondence with the three-way entrances and exits of the hoistway, baggage entrances are provided in the front side and three directions on both left and right sides of the cab. This can be assumed as an idea, but in this case, baggage entrances with wide entrances (large openings) are provided on three sides of the car compartment for convenience in loading and unloading luggage, so the car is not a box-like structure. The strength was weakened, the structure to ensure strength was difficult, and the problem was that it was difficult to implement.

An object of the present invention is to provide a car structure for a small cargo elevator that has cargo entrances and exits in three directions: the front side and both left and right sides of the cage, and yet has high car strength as a box body. Our goal is to provide the following.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides baggage entrances in three directions: the front side, the left side, and the right side of the car compartment, and the baggage entrances on the front side and the left side and right side. A corner pillar is erected at the corner of the car room adjacent to the baggage entrance, and three corner pillars are installed on the outside of the rear side plate of the car room where there is no baggage entrance and on the inside of the corner pillar.
The present invention is characterized in that the car compartment is supported by a car frame constructed by arranging book pillars and interconnecting the three pillars by an upper beam member and a lower beam member.

(Function) The upstanding pillars, which are constituent members of the car frame, reinforce the corner portion of the car room where the corner pillars are located. In addition, the car frame can be used to strengthen against lateral shaking and temporary overloading that occur when loading and unloading cargo.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
In the hoistway of a small cargo elevator equipped with b and 4c,
A car 2 and a counterweight 3 are provided in the hoistway 1 so as to be raised and lowered along a guide rail 5 in a hanging manner (not shown) by means of a main rope.

The car 2 is composed of a car room 20 and a car frame 30 that supports the car room 20, and three-way entrances and exits 4a and 4b of the hoistway 1 are provided on the front side, left side, and right side of the car room 20.
, 4c, there are three baggage entrances and exits 20a.

20b and 20c are provided, including a front luggage entrance 20a and left and right luggage entrances 20b and 20c.
Corner pillars 23a and 23b made of a shaped material as shown in FIG. 1 are erected at the corner portions of the cage adjacent to each other. There are three vertical pillars 22a, 22b made of channel members on the inner side of the corner pillars 23a, 23b and on the outer central part of the rear side plate 24 of the car room where there is no baggage entrance/exit.
.

22c are arranged as shown in Fig. 1, and these three standing pillars 22a.

Upper beam members 21a and 21b to which 22b and 22e are attached by welding, bolts, nuts, rivets, etc.
and the lower beam members 2[ia and 26b are connected to each other as shown in FIG. 2 to form a car frame 30, and the car frame 3o supports the car chamber 20 and connects the local parts thereof.
The car has a structure in which the car and the car compartment 20 are integrated.

In addition, the said Example is the upper beam member 21a of the car frame 3o.

21b and the lower beam members 26a and 26b are members with an H-shaped cross-section, but they may also be formed with a member with a groove-shaped cross-section, and the vertical columns 22a to 22c may also be formed with a member with an L-shape, a closed-type cross-section, or the like. It may be formed by

〔Effect of the invention〕

The car structure of the small cargo elevator of the present invention has three vertical pillars, which are constituent members of the car frame, arranged at three locations: the inside of the car room corner pillar and the outside of the car room rear side plate. The car compartment is supported by the car frame, which is constructed by interconnecting the book pillars with the upper and lower beam members, so it is structurally strong despite having cargo entrances and exits in three directions. It becomes possible to provide a small elevator for luggage that can be used as a car and has a three-way entrance and exit, which is often requested by customers.
