ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a joint of a foldable bed for babies. The bed can be folded to a smaller size for storage when not in use; the bed is foldable at the joint.
Referring to
FIGS. 8 and 9
, a heretofore known joint of a foldable bed comprises a main body
10
, auxiliary parts
20
, a pressing part
30
and two confining plates
40
as the main parts.
The main body
10
has two side plates
101
and an intermediate portion
104
. The side plates
101
each has an upper and a lower locating holes
102
and
103
. The intermediate portion
104
has an engaging hole
105
having engaging edges
106
protruding downwards therefrom. A spring
107
is connected to the engaging edges
106
.
The auxiliary parts
20
each has holes
201
and a locating hole
203
. Supporting rods of the foldable bed is coupled to the auxiliary parts
20
with locating pins
202
inserted into the supporting rods and the holes
201
. The locating pin
202
, as shown in
FIG. 9
, are also inserted through the upper locating holes
102
of the main body
10
such that the supporting rods and the auxiliary parts
20
can pivot on the main body
10
. The locating holes
203
of the auxiliary parts
20
are each connected with a locating pin
204
.
The pressing part
30
has two guide channels
301
, two recesses
302
, a through hole
303
and a holding hole
304
.
The confining plates
40
each has curved guide portions
401
, hooked portions
402
and a hole
403
. The confining plates
40
are held by the recesses
302
of the pressing part
30
; a fixing pin
404
is inserted into the holes
403
and
303
to fix the confining plates
40
to the pressing part
30
.
The pressing part
30
is movable fitted to the main body
10
with locating pins
108
passed through the guide channels
301
, and the lower locating holes
103
. The holding hole
304
holds a lower end of the spring
107
when the pressing part
30
is fitted to the main body
10
.
Furthermore, each of the locating holes
203
of the auxiliary parts
20
has a locating pin
204
inserted therein.
Whereby, the auxiliary parts
20
can pivot on the main body
10
for the bed to be folded when the pressing part
30
is pressed upwards to disengage the locating pins
204
from the hooked portions
402
of the confining plates
40
.
However, it is found that the joint of the foldable bed has undesirable features as follows.
1. Comprising one main body, two auxiliary parts, one pressing part, two confining plates and several locating pins, the joint has too many parts. So, the assembly process is relatively complicated.
2. In assemblying, the supporting rods have to be coupled to the auxiliary parts, and the confining plates have to be coupled to the pressing parts before same are fitted to the main body, costing relatively much time and labor.
SUMMARY
It is a main object of the present invention to provide a joint for a foldable bed which has relatively uncomplicated structure, and can be assembled easily.
The joint comprises:
a main body having two sides plates and an intermediate curved portion connecting the side plates the intermediate portion having two downwardly extending stopping plates;
a pressing block slidably fitted to the main body between the side plates; the pressing block having a round hole on a top receiving a spring for biasing the pressing block downwards, the pressing block having two engaging trenches on two sides thereof;
two supporting members respectively have a curved portion, an elastic plate, and an engaging protrusion; the supporting members being pivotted to the main body with the elastic plates located between the stopping plates of the main body, the engaging protrusions being capable of engaging a respective one of the engaging trenches for locating the supporting members at a first position; two supporting rods of the foldable bed being pivotted to the main body with inner ends contacting a respective curved portions of the supporting members when the supporting members are located at the first position;
the pressing block being pressed upwards to disengage the engaging trenches from the engaging protrusions for the supporting members to become pivotable on the main body;
Whereby the inner ends of the supporting rods can move away from the curved portions and the supporting rods can pivot on the main body for the bed to be folded.
The joint of a foldable bed of the present invention has only four main components, i.e. the main body, the supporting members and the pressing block, so it can be assembled relatively easily.
