ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a base of a foldable baby bed, which an be folded to a smaller size when not in use.
A heretofore known foldable bed base, referring to
FIGS. 9 and 10
, comprises a connecting rod combination
9
, supporting members
10
and movable members
20
as the main parts.
The connecting rod combination
9
consists of straight rods
91
and bent rods
92
. The straight rods
91
are respectively pivoted to the bent rods
92
. The rods
91
and
92
each has an elongated hole
911
,
921
at inner ends thereof. Stationary supports
94
are connected to the rods
91
and
92
for supporting them at the position where the rods
91
and
92
are pivoted to each other. The stationary supports
94
each has a curved recess
941
for the corresponding bent rod
92
to be located thereon, and a through hole
942
for receiving a bolt used to pivot the rods
91
to the coresponding rod
92
. Each of the stationary supports
94
further has a supporting leg
943
.
Each of inner ends of the rods
91
and
92
is connected with a connecting member
93
; the connecting members
93
each has a tube part
931
having a through hole
932
, and a connecting tube
933
having a sloped locating surface
934
and a through hole
935
.
The supporting members
10
each has two opposing gaps
101
, a hole
102
, a supporting leg
105
and a locating trench
106
. The supporting legs
105
are arranged under the transverse rods
104
; holes
107
are provided on the transverse rods
104
into order for a bolt
108
to pass therethrough to pivot one of transverse rods to the other.
The movable members
20
each has a C-shaped gap
201
at one end, and a platform portion
202
at the opposing end; the platform portions
202
each has a supporting leg
203
thereunder.
In combination, the connecting plate parts
933
of the connecting members
93
are passed into and, by means of a bolt, pivoted to a respective one of the gaps
101
of the supporting members
10
. The inner ends of the rods
91
,
92
are each passed into a respective one of the connecting members
93
. A bolt for a pivotal connection pivots the through hole
932
and the elongated hole
921
.
A bolt
108
is passed through the through holes
107
of the transverse rods
104
for pivotally connecting the transverse rods
104
; washers
109
,
100
are used on the holes
107
before the bolt
108
is passed into the holes
107
. Furthermore, the movable members
20
are pivoted to the supporting members
10
by connecting the C-shaped gaps
201
to a respective one of the annular recesses
103
of the supporting members
10
.
However, it can be seen that the base of the foldable bed has too many components, making the structure very complicated, and the assembling relatively labor-costing.
SUMMARY
Therefore, it is a main object of the present invention to provide a base of a foldable baby bed which has relatively few components and can be assembled very easily in order for the manufacturing cost to become lower than the prior art one.
The base of a foldable baby bed of the present invention comprises:
a connecting rod combination consisting of four connecting rods;
a middle member having a supporting pole, two hollows at two sides of the supporting pole, second connecting protrusions at two ends of the middle member, and first connecting protrusions between the hollows and the second connecting protrusions; springs being received in the hollow;
a first pivotal rod having a curved recess at an outer end thereof; the first pivotal rod being pivoted to one of the first connecting protrusions from a middle part thereof; the first pivotal rod further having a locating block at an inner end, passed into the corresponding one of springs in the hollows;
a second pivotal rod having a curved recess at an outer end thereof; the second pivotal rod being pivoted to the other first connecting protrusions from a middle part, and being biased downwards by the other spring of the hollow at an inner end; the inner end of the first pivotal rod being pivoted to the inner end of the second pivotal rod, and connected with a belt such that the inner end of the rods can be lifted to pivot the rods by pulling the belt;
two turning members each having a rod part pivot a respective one of the second connecting protrusions; the connecting rods being pivoted to the turning members; the rod parts each having two stopping elements opposing each other; the upper ones of the stopping elements are located adjacent to a wall of the middle member between the second connecting protrusions to stop the rod parts from turning inwardly; the lower ones of the stopping elements being each located in a respective one of curved recesses on the outer ends of the first and the second rods when the belt is not pulled, stopping the rod parts of the turning members from turning when the foldable bed is stretched to an in-use position.
It can be seen that the base of a foldable bed of the present invention has relatively few components, and can be assembled with less labor than the prior art one.
