Abstract

PROBLEM TO BE SOLVED: To constantly hold pressing force against the traveling rail of a brake when a cable is disconnected or loosened by providing a push rod for pressing an outside cotter toward an elevating passage at the higher direction by spring force evolved by releasing a stopper. SOLUTION: A disconnected or loosened cable strikes a striker 21 to release a stopper 17 from the collar 18a of a push rod 18. Then, the push rod 18 jumps by the spring force of a compressed coil spring 18c. Its tip end simultaneously pushes an inside cotter 10 by the projected part 9a of the outside cotter 9. The pushed outside cotter 9 and the pushed inside cotter 10 move the brake shoes 13 of a pushing-receiving seat 12 to a traveling rail 2 side by the action of the slope face 8 of a brake body 7 at its bottom face 7a. The brake shoe 13 of the pushing-receiving seat 12 is pushed against the traveling rail 2. Where, a bellevile spring 14 acts as a cushioning material to stop a traveling carriage with pushing force constantly retained.

In the above-mentioned embodiment, a pair of brakes having the same structure are provided so as to face each other with the traveling rail interposed therebetween. However, one brake has the same structure as the above-mentioned embodiment, and the other brake has the above-mentioned structure. Instead of the structure of the embodiment, a simple structure in which the outer cotter and the inner cotter of the above embodiment are removed may be used as shown in FIGS. 6 and 7. The brake main body 26 is formed in a box shape whose side facing the traveling rail 2 is open, and the bottom surface 26 a has the hoistway 1.
The inclined surface 27 has an inclination angle such that it approaches the traveling rail 2 side in the high direction. Reference numeral 28 denotes a pressing seat that is fitted and inserted in the brake body 26, and has a brake shoe 29 fixed to the inner end. By adopting such a structure, the cost of the brake as a whole is low, and it is effective in the case where there is a limitation on the installation location of the brake. The operation of the pressing seat 28 is substantially the same as the operation of the above-described embodiment, and the description thereof will be omitted because it overlaps.

Further, in the above embodiment, the pair of brakes are provided so as to face each other with the traveling rail interposed therebetween, but as shown in FIG. 8, the traveling rail is replaced with a traveling rail. May be provided with another fixed rail 30, and a brake may be provided with the fixed rail 30 sandwiched therebetween.

The present invention is not limited to the above-described embodiment. For example, two vehicles may be provided in front of and behind the traveling vehicle, and even if there is only one cable, the wheels have the same structure on the left and right. Needless to say, various modifications are possible without departing from the spirit of the present invention.

[0024]

As described above, according to the present invention,
The cable car has an outer cotter having an inclination angle that quickly presses the gap between the traveling rail and the brake shoe, and an inner cotter having an inclination angle that is gentler than the inclination angle of the outer cotter that gently presses the brake shoe onto the traveling rail. Even if the vehicle suddenly stops, the impact at the time of stopping can be minimized, and it is possible to achieve an excellent effect such as a safe and sure stop.
