JPH0517091A - Three-side frame fixing device for elevator - Google Patents

Abstract

PURPOSE:To improve the positioning workability of a three-side frame by permitting execution of the connection between a doorsill and a three-side frame without using bolts by inserting the cut part of a longitudinal frame from the above into the cut part of a sidesill metal fitting installed on a doorsill and engaging both when door the longitudinal frame is fixed on the doorsill. CONSTITUTION:When longitudinal frames 1 and 2 are fixed on a doorsill 11, the cut parts of the longitudinal frames 1 and 2 are inserted from the above into the cut part of a doorsill metal fitting installed on the doorsill 11 and engaged. If the doorsill metal fitting is installed on the doorsill 11 when forward from a factory, the use of bolts in the three-side frame positioning work at a site is omitted. Accordingly, the positioning workability of the longitudinal frame of the three-side frame can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator three-way frame fixing device capable of easily connecting a sill and a three-way frame.

[0002]

2. Description of the Prior Art The closest known example of the present invention is SAIkai 49-13.
This is 9840.

A conventional fixing device for an elevator three-way frame will be described with reference to FIGS. 1, 4, 5, and 6. FIG. 4 is a view of the entrance / exit of the elevator from the landing side. 1 is a right vertical frame, 2 is a left vertical frame, 3 is an upper frame, 4 and 5 are doors on the side of the landing, and 6 is a hall car call device. 1 is a view of the entrance of the elevator as seen from the hoistway side. In the figure, 7 is a door hanger for suspending the doors 4 and 5, and a door rail 9 assembled in a pocket 8.
Open and close the doors 4 and 5 along. The pocket 8 is fixed to the hoistway wall by a bracket 10. The sill 11 is fixed to the hoistway wall by a bracket 12, and the doors 4 and 5 are opened and closed along a door guide groove 11a provided in the sill 11. The vertical frames 1 and 2 and the sill 11 are fixed to each other by the sill 11
The sill metal fitting 14 attached to the building 13 and the reinforcement 15 attached to the lower portions of the vertical frames 1 and 2 by welding are performed by connecting the frame bracket 16 with bolts 17 and 18.

In the conventional three-way frame and sill thus constructed, the sill metal fitting 14 is attached to the sill 11 with screws 13 after the sill 11 is attached to the floor, while the vertical reinforcements 15 are attached to the vertical frames 1 and 2. The frame bracket 16 was fixed with bolts 17 in the end, and finally the frame bracket 16 and the sill bracket 14 were connected with bolts 18 to align the three-way frame. The alignment of the three-way frame is to ensure the position of the left and right vertical frames with respect to the entrance / exit core and the position of the vertical frame with respect to the door surface that secures an expected clearance dimension with the door when the door is suspended.

[0005]

In the above-mentioned conventional example, the three-way frame and the sill are bolted together. Therefore, (1) the hole of the sill metal fitting 14 needs to be larger than the diameter of the bolt 17, and the vertical frame position. Fine adjustment is necessary for centering.

(2) A large amount of time is required for the bolt tightening work.

There is a problem in assembling such as.

It is an object of the present invention to improve the efficiency of the three-way frame alignment work by simplifying the method of connecting the three-way frame and the threshold.

[0009]

[Means for Solving the Problems] The above object is to connect the metal fittings attached to the sill and the three-sided frame without bolts.
This is achieved by engaging the metal fitting attached to the sill and the three-sided frame as the connecting means with the notched portions facing each other.

[0010]

[Operation] By making notches in the parts facing the metal fittings attached to the sill and the three-way frame, and engaging the notches to align the three-way frame, the work time for aligning the three-way frame is greatly reduced. To be done. When the notch of the metal fitting attached to the sill and the notch provided in the three-way frame are engaged, the width direction of the entrance and exit and the direction of entrance and exit of the three-way frame are restricted, so that the lower part of the three-way frame can be fixed and aligned at the same time.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 shows an embodiment of the three-way frame fixing device of the present invention and is equivalent to FIG. A sill metal fitting 14 having a notch 14a and a mounting hole 14b as shown in FIG. 7 is attached to the sill 11 by means of a screw 13, while a cut 14a of the sill metal fitting 14 is attached to the lower portion of the vertical frame 2 of the three-way frame. A notch 2a is provided at a position facing each other.

In the fixing device of the three-sided frame constructed as described above, in order to fix the vertical frames 1 and 2 to the sill 11, the vertical frames 1 and 2 are cut into the notches 14a of the sill metal fitting 14 attached to the sill 11. It suffices to insert 1a (not shown) and 2a by inserting them from above. At this time, if the sill metal fitting 14 is attached to the sill 11 at the time of shipment from the factory, it is not necessary to use bolts in the three-way frame alignment work on site.

Another embodiment of the present invention is shown in FIGS. The reinforcement 15 attached to the lower portion of the vertical frame 2 is provided with a cut 15a corresponding to the cut 2a shown in FIG. 3 to obtain the same effect.

[0015]

According to the present invention, since the sill and the vertical frame of the three-way frame can be connected without using bolts, the workability of aligning the three-way frame is greatly improved.
