Damper For Elevator And Elevator

Abstract: Provided are a damper for elevator, and an elevator, that enable reduction of the maximum deceleration of a lifting/lowering body by suppressing deformation of a foamed body for absorbing impact. The damper for elevator (10) includes: urethane foam (11) having a collision surface (lla) with which a lifting/lowering body is to collide; and an outer peripheral member (12) attached to the outer side of the side-part surface of the urethane foam (11) and having an inner.., side surface (12a) bowed outward, wherein impact by collision of the lifting/lowering body is buffered by deformations of the urethane foam (11) and the outer peripheral member (12).

Specification

[ 1] A damper for elevator comprising:
a foamed body having, at an upper part, a collision surface with which a lifting/lowering body is to collide; and
an outer peripheral member which is attached to an outer side of a side-part surface of the foamed body and of which a side facing the side-part surface is bowed outward, wherein
impact by collision of the lifting/lowering body is buffered by deformations of the foamed body and the outer peripheral member.
[ 2] The damper for elevator according to claim 1, wherein
a height of the outer peripheral member is not less than 50% of a height of the foamed body.
[3] The damper for elevator according to claim 1 or 2, wherein
a height of the outer peripheral member is not greater than a height of the foamed body.
[ 4] The damper for elevator according to claim 3, wherein
an upper end surface of the outer peripheral member

is covered by the foamed body.
[5] The damper for elevator according to any one of
claims 1 to 4, wherein
a thickness of the outer peripheral member is not greater than 50% of a height of the foamed body that is maximally compressed.
[6] The damper for elevator according to any one of
claims 1 to 5, wherein
a thickness of the outer peripheral member is
uniform.
[7] The damper for elevator according to any one of
claims 1 to 6, wherein
the outer peripheral member has a hollow
cylindrical shape.
[8] The damper for elevator according to any one of
claims 1 to 6, wherein
the outer peripheral member is composed of a plurality of plate-shaped members arranged so as to be spaced from each other.
[9] The damper for elevator according to any one of

claims 1 to 6, wherein
the outer peripheral member is composed of a plurality of columnar members arranged so as to be spaced from each other.
[10] An elevator comprising:
a lifting/lowering body capable of being lifted/lowered in a hoistway; and
the damper for elevator according to any one of claims 1 to 9, the damper for elevator being provided at a lower end part of the hoistway and located under the lifting/lowering body.
