Abstract

According to one embodiment of the present invention, there is provided a buffer cap for an elevator to be placed on an upper surface of a buffer provided below a counterweight for an elevator so as to be opposed to a lower surface of the counterweight, which is configured to restrict lowering of the counterweight, the buffer cap including: a support column; an upper plate provided to an upper end of the support column; and a lower plate provided to a lower end of the support column, wherein the support column is formed of flat plates, and each of the upper plate and the lower plate is formed of a flat plate, and wherein the flat plates for forming the support column, and the flat plates for the support column and the upper plate or the lower plate are fittable and disassemblable.

First claim

The invention claimed is:

1. A buffer cap to be placed on an upper surface of a buffer provided below a counterweight for an elevator so as to be opposed to a lower surface of the counterweight, which is configured to restrict lowering of the counterweight, the buffer cap comprising:
a support column;
an upper plate provided to an upper end of the support column; and
a lower plate provided to a lower end of the support column,
wherein the support column is formed of flat plates, and each of the upper plate and the lower plate is formed of a flat plate,
wherein the flat plates for forming the support column, and the flat plates for the support column and the upper plate or the lower plate are fittable and disassemblable from each other,
wherein the support column is formed of a flat plate having a groove cut out from an upper end to have a predetermined length in a vertical direction and a flat plate having a groove cut out from a lower end to have a predetermined length in the vertical direction, which are arranged so as to cross each other with the grooves being opposed to each other on a cross section, and
wherein tenons are formed at the upper end and the lower end of the support column, whereas mortises to be fitted to the tenons are formed through the upper plate and the lower plate, respectively.

2. The buffer cap according to claim 1 ,
wherein the buffer cap comprises an upper buffer cap and a lower buffer cap,
wherein the buffer caps are arranged so as to be stacked in the vertical direction, and
wherein the tenon formed at the lower end of the support column of the upper buffer cap and the mortise formed through any one or both of the lower plate of the upper buffer cap and the upper plate of the lower buffer cap are fitted to each other in order to assemble the upper cap and the lower buffer cap together.
