Description
BACKGROUND OF THE INVENTION
[0001] 1. Fields of the Invention
[0002] The present invention relates to a support member of
foldable travel bed, especially to a support member of a foldable
travel bed that supports the foldable travel bed stably when the
travel bed is extended. The travel bed can be folded into two
halves and then extended in use.
[0003] 2. Descriptions of Related Art
[0004] Refer to Taiwanese Pat. Pub. No. M382780 "double tube
structure of upper frame of travel bed", it reveals an upper frame
of a travel bed. Each side of the travel bed includes a joint on a
center part thereof. By the joints, each side of the upper frame of
the travel bed can be folded for storage.
[0005] Refer to Taiwanese Pat. Pub. No. M345539 "locking member of
travel bed frame", it has structure similar to that of the above
patent. A joint is arranged at each side of an upper frame of a
travel bed. Thus each side of the upper frame of the travel bed can
be folded for storage by the joints.
[0006] In the above patents, while the travel bed being folded, a
lower frame is pulled up and folded from a bottom base first and
then four sides of the upper frame are folded by pulling upper
corner seats toward a center. The upper corner seat is located
between two adjacent sides of the upper frame and a vertical rod.
Thus the travel bed needs joints each of which is arranged at each
of four sides of the upper frame and the upper corner seats each of
which is between two adjacent sides and the vertical rod. The two
adjacent sides are pivoted by the upper corner seat. Such fold and
extend mode is more trouble and inconvenient in use. Moreover, the
upper corner seat has a certain volume for pivoting the two
adjacent sides and fixing the vertical rod. Thus the upper corner
seats at four corners of the travel bed occupy a certain space
after the travel bed being folded. The manufacturing cost is also
increased.
[0007] Thus there is room for improvement and a need to provide a
novel foldable travel bed that can be folded into two halves and
having a good support structure after being extended. Thus the
foldable travel bed is of higher practical value.
SUMMARY OF THE INVENTION
[0008] Therefore it is primary object of the present invention to
provide a support member of a travel bed by which a frame of the
travel bed is folded into two halves for storage and the frame is
supported firmly as well as stably while being extended.
[0009] In order to achieve the above object, a support member of a
travel bed provided by the present invention includes two side
frames and two fastening joints. Through releasing of fastening
state of each fastening joint, a connecting rod and two vertical
rods of one side frame are moved toward to those of the other side
frame. Thus the travel bed is folded into two halves for storage. A
transverse rod, the connecting rod and the vertical rod are
connected by a pivot connector. A stopper assembly is disposed
between the transverse rod and the vertical rod. The stopper
assembly includes a slide sleeve and a link rod. The slide sleeve
is sleeved on the transverse rod while two ends of the link rod are
respectively pivoted to the slide sleeve and the vertical rod.
Thereby the travel bed is extended stably due to the disposition of
the stopper assembly.
[0010] Moreover, a lower frame is arranged at a bottom end of each
vertical rod. The lower frame is formed by a plurality of support
rods. An outer end of each support rod is connected to a bottom end
of the corresponding vertical rod while an inner end of each
support rod is connected by a base seat.
[0011] The bottom end of the vertical rod is further assembled with
a wheel or a support leg.
[0012] The above pivot connector includes two co-axial sleeves at a
first direction and a curved slot along the same axis of the
sleeves at a second direction. The sleeves are arranged parallel to
each other and respectively inserted through by the connecting rod
and the transverse rod. A slot is formed between the two sleeves
and a stopper fixed on the transverse rod is mounted in the slot.
Two side walls of the curved slot are fixed on the vertical
rod.
