Abstract

A detachable supporting leg for a baby playpen is disclosed. The supporting leg comprises a leg body and a coupling block releasably coupled with each other. The leg body has an upper coupling portion and a lower supporting portion integrally connected by a horizontal supporting wall. The coupling block is releasably coupled with the coupling portion of the leg body so as to be supported on the supporting wall. The coupling block is adapted to fixedly connect thereto an end portion of a vertical rod of the baby playpen and to pivotally connect thereto an end portion of a horizontal base rod of the baby playpen.

A supporting leg for a baby playpen, comprising:

a leg body having an upper coupling portion and a lower supporting portion integrally connected by a horizontal supporting wall, said coupling portion including a substantially U-shaped vertical wall extending upwards from said supporting wall, said vertical wall having a first wall portion, a second wall portion parallel to said first wall portion, an end wall portion integrally connected between said first wall portion and said second wall portion and an inwardly extending flange integrally formed along an upper edge of said vertical wall;
and
a coupling block inserted between said flange and said supporting wall so as to be releasably coupled with said coupling portion and supported on said supporting wall, said coupling block being adapted to fixedly connect thereto an end portion of a vertical rod of said baby playpen and to pivotally connect thereto an end portion of a horizontal base rod of said baby playpen, said coupling block comprising:
a bottom surface abutting on an upper surface of said supporting wall;
a first side surface abutting against an inner surface of said first wall portion;
a second side surface abutting against an inner surface of said second wall portion;
a first end surface abutting against an inner surface of said end wall portion;
a second end surface exposed between free end surfaces of said first wall portion and said second wall portion;
and
a top surface including a surface portion abutting against a lower surface of said flange and an exposed surface portion;
wherein a vertical hole is defined in said exposed surface portion of said top surface near said first end surface;
a first countersunk hole is defined in said first side surface so as to communicate with said vertical hole;
and a second countersunk hole is defined in said second side surface so as to communicate with said vertical hole;
whereby said end portion of said vertical rod of said baby playpen is inserted into said vertical hole so as to be fixedly connected to said coupling block;
and
wherein a horizontal slot is defined in said exposed surface portion of said top surface and extending from said second end surface to a vicinity of said vertical hole;
a third countersunk hole is defined in said first side surface so as to communicate with said slot;
and a fourth countersunk hole is defined in said second side surface so as to communicate with said slot;
whereby said end portion of said horizontal base rod of said baby playpen is received in said slot so as to be pivotally connected to said coupling block.
