Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the invention
[0002] The present invention relates to a joining structure of an
upper corner piece and rod parts of a baby mesh bed, more
particularly one, which prevents the joints between the upper
corner piece and the rod parts from being exposed, and allows the
rod parts to be easily separated from the upper corner piece for
maintenance, repair and replacement of cloth and mesh members and
the joints of the mesh bed.
[0003] 2. Brief Description of the Prior Art
[0004] FIG. 10 is an exploded perspective view of a traditional
joining structure of an upper corner piece 91 and upright and
transverse rod parts 93 and 92 of a baby mesh bed. The upper corner
piece 91 comprises single part, and is angled to have an angle
portion. The upper corner piece 91 has a receiving section 911
inside the angle portion, and holding rooms on two sides of the
angle portion. The upright rod part 93 is inserted in and securely
joined to the receiving section 911 of the upper corner piece 91.
The transverse rod parts 92 are each held in a corresponding said
holding room at a first end with a pivotal hole, and pivoted on a
pivotal element 921 passed through the pivotal hole thereof as well
as connecting holes of the upper corner piece 91. Therefore, the
transverse rod parts 92 can be angularly displaced relative to the
upper corner piece 91.
[0005] The above structure has the following drawbacks: the pivotal
elements 921 stick out from two sides of the upper corner pieces at
two ends thereof to spoil the appearance of the upper corner piece.
And, in assembly, it will take some much time to adjust position of
the transverse rod parts 92 in order for the pivotal holes of the
transverse rod parts 92 to face corresponding connecting holes on
the upper corner piece 91 to allow the pivotal elements 921 to pass
through. Therefore, the above structure is relatively slow to
assemble.
SUMMARY OF THE INVENTION
[0006] It is a main object of the present invention to provide an
improvement on a joining structure of an upper corner piece and rod
parts of a baby mesh bed to overcome the above problems.
[0007] A mesh bed according to an embodiment of the present
invention; the upper corner piece includes an upper corner piece,
and rod parts. The upper corner piece comprises an inner and an
outer wall portions at each of two end portions thereof, internal
rooms between the inner and the outer wall portions, and an
internal sleeve portion securely disposed between the internal
rooms. The rod parts include two transverse rod parts; the
transverse rod parts are each pivoted to one coupling piece, which
is held in one said internal room of the upper corner piece, and
securely joined to the sleeve portion of the upper corner piece by
means of fixing elements. The rod parts include an upright rod
part, which is also securely joined to the sleeve portion of the
upper corner piece at an upper end by means of the fixing
elements.
[0008] Therefore, the joints between the upper corner piece and the
rod parts of the mesh bed are covered with the upper corner piece
instead of being exposed, without spoiling the appearance of the
upper corner piece. And, after the fixing elements have been
loosened, the upright rod part and the coupling pieces with the
transverse rod parts can be separated from the upper corner piece
in order for cloth and mesh members and the joints of the mesh bed
to be repaired, maintained, and replaced.

propped against the propping portion 143 of the sleeve portion 14
of the upper corner piece 1 at lower ends thereof to help to hold
the coupling pieces 3 and the transverse rod parts 4. Therefore,
the transverse rod parts 4 pivot on the upper corner piece 1.
[0025] Therefore, after the fixing elements 35 have been loosened
by means of a tool, the upright rod part 2 and the coupling pieces
3 with the transverse rod parts 4 can be easily separated from the
upper corner piece 1 in order for cloth and mesh members and the
joints of the baby mesh bed to be repaired, maintained, and
replaced with a new one.
[0026] Shown in FIG. 6 is a second preferred embodiment of a baby
mesh bed of the present invention. The mesh bed includes an upper
corner piece 5, an upright rod part 6, and two transverse rod parts
8.
[0027] The upper corner piece 5 comprises single part, and is
angled. The upper corner piece 5 includes inner and outer wall
portions 51 and 52, and an internal room 53, which intervenes
between the inner and the outer wall portions 51 and 52, and
extends to two ends of the upper corner piece 5. The upper corner
piece 5 includes a sleeve portion 54 in an intermediate angle
portion of the internal room 53 thereof. The sleeve portion 54 has
a bottom opening, and two grooves 541 thereon, which each face one
of said two open ends of the internal room 53 of the upper corner
piece 5. The sleeve portion 54 further has a fixing hole 542 on
each of the grooves 541 thereof. The sleeve portion 54 further has
a fitting groove 543, which intervenes between the grooves 541 on
an upper portion thereof, and has a curved surface.
[0028] The upright rod part 6 is positioned around the sleeve
portion 54 of the upper corner piece 5 at an upper end thereof. The
upright rod part 6 has two through holes 61, which each face a
corresponding said fixing hole 542 of the sleeve portion 54. The
upright rod part 6 further has a fitting portion 62 on an inner
side of a corner thereof, which is inserted in the fitting groove
543 of the sleeve portion 541 of the upper corner piece 5.
[0029] Each of the transverse rod parts 8 has a pivotal hole (not
numbered) at a first end thereof, and is pivoted to a coupling
piece 7; each coupling piece 7 has an upright end wall portion 71,
two connecting wall portions 72 projecting from two sides of the
end wall portion 71, and a pivotal hole 721 on each of the
connecting wall portions 72, as shown in FIG. 6; each coupling
piece 7 further has a protruding portion 74 sticking rearwards from
a rear side of the upright end wall portion 71 thereof, which
protruding portion 74 is in the shape of a "T", and which has a
through connecting hole 741 thereon. Each of the transverse rod
parts 8 is pivoted to a respective said coupling piece 7, with the
first end thereof being received between the connecting wall
portions 72 of the coupling piece 7, and with a pivotal element 73
being passed through the pivotal holes 721 as well as the pivotal
hole of the transverse rod part 8.
[0030] In assembly, referring to FIGS. 7, 8, and 9, each of the
coupling pieces 7 with a corresponding said transverse rod part 8
is positioned in one of two end portions of the internal room 53,
with the protruding portion 74 being inserted in a corresponding
said groove 541 of the sleeve portion 54 of the upper corner piece
5. Next, the upright rod part 6 is positioned around the sleeve
portion 54 of the upper corner piece 5 at the upper end thereof,
with the fitting portion 62 thereof being inserted in the fitting
groove 543 of the sleeve portion 541. And, fixing elements 75 are
passed through the through holes 61 of the upright rod part 6, the
through connecting holes 741 of the coupling pieces 74, and the
fixing holes 542 of the sleeve portion 54 of the upper corner piece
5 so as to secure the coupling pieces 7 to the sleeve portion 54 as
well as the upright rod part 6. Therefore, the transverse rod parts
8 pivot on the upper corner piece 5.
[0031] Therefore, after the fixing elements 75 have been loosened
by means of a tool, the upright rod part 6 and the coupling pieces
7 with the transverse rod parts 8 can be easily separated from the
upper corner piece 5 in order for cloth and mesh members and the
joints of the mesh bed to be repaired, maintained, and replaced
with a new one.
[0032] From the above description, it can be seen that the present
invention has the following advantages:
[0033] 1. The joint between the upper corner piece and each of the
rod parts is covered with the upper corner piece instead of being
exposed. Therefore, the appearance of the whole upper corner piece
isn't spoiled.
[0034] 2. The upper corner piece and the transverse rod parts of
the first preferred embodiment are coupled together by means of the
coupling pieces, which are securely joined to the sleeve portion of
the upper corner piece with the hooking portions being hooked over
the hooking holes of the sleeve portion and with the fixing
elements being passed through the coupling pieces and the sleeve
portion. Therefore, after the fixing elements have been loosened,
the upright rod part and the coupling pieces with the transverse
rod parts can be separated from the upper corner piece in order for
cloth and mesh members and the joints of the mesh bed to be
repaired, maintained, and replaced.
[0035] 3. Furthermore, according to the first embodiment, the
fixing elements can be easily passed through the connecting holes
of the coupling pieces and the fixing holes of the sleeve portion
of the upper corner piece because the connecting holes will face
corresponding said fixing holes automatically when the hooking
portions of the coupling pieces are hooked over the hooking holes
of the sleeve portion.
[0036] 4. According to the second preferred embodiment, the upper
corner piece has the internal sleeve portion, and is coupled to the
transverse rod parts by means of the coupling pieces, which are
securely joined to the sleeve portion of the upper corner piece
with the fixing elements being passed through the coupling pieces
and the sleeve portion. And, the upright rod part is also securely
joined to the internal sleeve portion by means of the fixing
elements. Therefore, after the fixing elements have been loosened,
the upright rod part and the coupling pieces with the transverse
rod parts can be separated from the upper corner piece.
