Abstract

A laundry drying implement includes a casing; a hollow bearing portion protruding in the casing; a drum that is supported on the hollow bearing portion, and rotatable about the hollow bearing portion; a laundry rope that is wound around the drum, and can be unreeled from and reeled onto the drum as the drum rotates; and a rotary damper that is received in the hollow bearing portion, and applies rotational resistance to the drum in a rope-reeling direction.

Claims4

Dependent claims

A laundry drying implement comprising:

a casing having a pull-out port in a front surface of the casing, and being attachable to one of two wall surfaces in indoors of a building with a back surface of the casing opposed to the one of the two wall surfaces;
a hollow, cylindrical bearing portion protruding in the casing such that a center axis of the hollow, cylindrical bearing portion coincides with a front-to-back-surface direction of the casing;
a drum supported on the hollow, cylindrical bearing portion, and rotatable about the hollow, cylindrical bearing portion in normal and reverse directions;
a laundry rope wound around the drum, and configured to be unreeled from and reeled onto the drum as the drum rotates in the normal and reverse directions;
a guide mechanism configured to change an unreeled direction of the laundry rope from the drum such that the laundry rope can be pulled out through the pull-out port of the casing in the front surface of the casing;
an engagement part which is attached to a distal end of the laundry rope, and via which the laundry rope is engageable with the other of the two wall surfaces, with the laundry rope pulled out;
a flat spiral spring biasing the drum in a rope-reeling direction in which the laundry rope is reeled onto the drum;
a rotary damper received in the hollow, cylindrical bearing portion, and configured such that when a braking shaft of the rotary damper rotates in unison with the drum, the rotary damper applies rotational resistance to the drum in the rope-reeling direction;
and
a cylindrical spring case in which the flat spiral spring is stored, and which is configured to rotate in unison with the drum within the casing,
wherein the cylindrical spring case includes a boss portion coupled to the braking shaft of the rotary damper so as to axially pass through the hollow, cylindrical bearing portion on a rotation center axis of the cylindrical spring case.
