WE CLAIM:
[Claim 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, 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.
[Claim 2] The buffer cap according to claim 1,
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 an upper end and a lower end of the support column, whereas mortises to be fitted to the tenons
23

are formed through the upper plate and the lower plate, respectively.
[Claim 3] The buffer cap according to claim 1,
wherein the support column has a prismatic shape, and a first tenon protruding in a horizontal direction and a tenon groove to be fitted to the first tenon are formed alternately on both sides of a side surface portion in a vertical direction, for each of the flat plates for forming the side surfaces of the support column, and
wherein the first tenon and the tenon groove arranged adjacent to each other when viewed from above are fitted to each other, and a second tenon is formed at each of an upper end and a lower end of each of the flat plates for forming the side surfaces of the support column, whereas mortises to be fitted to the second tenons are formed through the upper plate and the lower plate, respectively.
[Claim 4] The buffer cap according to claim 1,
wherein the support column has a prismatic shape, and a hinge is provided on both sides of a side surface portion in a vertical direction for each of the flat plates for forming the side surfaces of the support column, and
wherein the flat plates for forming the side surfaces of the support column are coupled to each other with the hinges except at least at one position, and a tenon is formed at each of an upper end and a lower end of each of the flat plates for forming the side
24

surfaces of the support column, whereas mortises to be fitted to the tenons are formed through the upper plate and the lower plate, respectively.
[Claim 5] The buffer cap according to any one of claims 2 to 4, 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 buffer cap arranged on an upper side and the mortise formed through any one or both of the lower plate of the buffer cap arranged on the upper side and the upper plate of the buffer cap arranged on a lower side are fitted to each other to fit the buffer cap arranged on the upper side and the buffer cap arranged on the lower side to each other.
