Description
FIELD OF THE INVENTION
[0001] The present invention relates to a highchair, in particular
to a highchair that latches latch bumps into embedding holes and
engages a link axle with a latch groove to couple a seat with a leg
portion.
BACKGROUND OF THE INVENTION
[0002] As the society is developed rapidly in a diversified manner,
various different convenient products are developed and a safe and
convenient highchair provided for babies and children is one of
these products. However, most highchairs available in the market
come with a seat and a leg portion integrally formed with each
other, such that the use of the highchair or the utility of space
has limitations. Therefore, the inventor of the present invention
developed a highly secured and easily assembled/unassembled
highchair to overcome the foregoing problem.
SUMMARY OF THE INVENTION
[0003] It is a primary objective of the present invention to
provide a highchair, characterized in that latch bumps are latched
into embedding holes respectively and a link axle is engaged with a
latch groove to couple a seat with a leg portion.
[0004] To achieve the aforementioned objective, the present
invention provides a highchair comprising a seat and a leg portion,
wherein two embedding holes are formed on both sides of the seat
respectively, and a latch groove is formed at an end of the seat.
In addition, the leg portion includes two latch bumps and a link
axle, and the two latch bumps correspond to the two embedding holes
respectively, and the link axle corresponds to the latch groove,
such that the latch bumps can be latched into the embedding holes
respectively and the link axle is engaged with the latch groove to
couple the seat with the leg portion.
[0005] The highchair of the invention further comprises a footrest
coupled to the link axle and can be turned by using the link axle
as a main shaft. In addition, the highchair of the present
invention further comprises a tray mounted onto two handles of the
seat, such that a baby sitting on the highchair can eat while
sitting on the highchair. Further, a sitting portion of the seat
further comprises a flange provided for preventing the baby from
sliding down from the highchair. Obviously, the footrest and the
flange can provide a dual protection mechanism to prevent the baby
from sliding down from the highchair.
[0006] In summation, the seat and the leg portion of the highchair
of the present invention are coupled by the aforementioned latching
and engaging methods, not only providing a convenient way of
assembling and disassembling the seat and the leg portion of the
highchair, but also achieving the effect of securely coupling the
seat with the leg portion in directions of different axes. In other
words, a stable and reliable connection between the seat and the
leg portion in different degrees of freedom can be achieved.
Therefore, users simply need to separate the link axle and the
latch bumps from the latch groove and the embedding holes
respectively in a reverse sequence to disassemble the highchair
easily after the use of the highchair.
[0007] As described above, the highchair of the present invention
has the following advantages:
[0008] (1) In the highchair of the present invention, the seat and
the leg portion can be coupled securely and reliably in different
degrees of freedom.
[0009] (2) In the highchair of the present invention, users simply
need to separate the link axle and the latch bumps from the latch
groove and the embedding holes respectively in a reverse sequence
to achieve the effect of disassembling the highchair easily.
[0010] (3) In the highchair of the present invention, the footrest
and the flange constitute a dual protection mechanism for
preventing a baby from sliding down from the highchair.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 is a schematic view of an unassembled highchair of
the present invention;
[0012] FIG. 2 is a front view of an assembled highchair of the
present invention; and
[0013] FIG. 3 is a rear view of an assembled highchair of the
present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] The technical characteristics and contents of the present
invention will become apparent with the following detailed
description and related drawings. It is noteworthy to point out
that same numerals are used for representing respective same
elements in the drawings.
[0015] With reference to FIG. 1 for a schematic view of an
unassembled highchair of the present invention, the highchair
comprises a seat 10 and a leg portion 20, wherein two embedding
holes 101 are formed on both sides of the seat 10 respectively, and
a latch groove 102 is formed at an end of the seat 10. In addition,
the leg portion 20 includes two latch bumps 201 and a link axle
202, and the two latch bumps 201 correspond to the two embedding
holes 101 respectively, and the link axle 202 corresponds to the
latch groove 102. The latch bumps 201 can be latched into the
embedding holes 101 respectively and the link axle 202 can be
engaged with the latch groove 102 to couple the seat 10 with the
leg portion 20.
[0016] More specifically, the embedding holes 101 are in a circular
shape, and the latch bumps 201 are in a circular cylindrical shape,
so that users can simply couple the seat 10 to the leg portion 20
and latch the latch bumps 201 of the leg portion 20 into the
embedding holes 101 of the seat 10 respectively to complete the
first step of coupling the seat 10 with the leg portion 20. In the
process of coupling the seat 10 with the leg portion 20 by coupling
the embedding holes 101 with the latch bumps 201, the link axle 202
of the leg portion 20 is latched into the latch groove 102 of the
seat 10 to complete the second step of coupling the seat 10 with
the leg portion 20. Specifically, the sequence of the first and
second steps of coupling the seat 10 with the leg portion 20 is not
important, but either one of the steps can be carried out first, or
both steps can be carried out simultaneously.
[0017] The highchair of the present invention further comprises a
footrest 30 coupled to the link axle 202 and can be turned by using
the link axle 202 as a main shaft. In practical applications, the
footrest 30 and the link axle 202 are connected tightly with each
other. In other words, the footrest 30 can be turned and adjusted
slightly to fit the size of the baby who sits on the highchair,
such that the baby can step on the footrest 30 to prevent a
possible accident of sliding down from the highchair.
[0018] With reference to FIGS. 2 and 3 for a front view and a rear
view of an assembled highchair of the present invention
respectively, the seat 10 and the leg portion 20 of the highchair
are coupled by means of a latching or engaging method, not only
providing a convenient way of assembling and disassembly the seat
10 and the leg portion 20, but also achieving the effect of
coupling the seat 10 with the leg portion 20 in directions of
different axes. In other words, when the seat 10 and the leg
portion 20 are coupled, the seat 10 can be fixed to the footrest 30
and a support portion 203 of the leg portion 20 in a direction of
the X-axis. When the link axle 202 is latched into the latch groove
102 and the latch bumps 201 are latched into the embedding holes
101 respectively, the seat 10 is limited to a certain extent by the
leg portion 20 in the directions of Y-axis and Z-axis. In other
words, the seat 10 and the leg portion 20 can be coupled stably and
reliably in different degrees of freedom.
[0019] Therefore, users simply need to separate the latch groove
102 and the embedding holes 101 from the link axle 202 and latch
bumps 201 respectively in a reverse sequence to disassemble the
highchair easily after the use of the highchair.
[0020] In addition, the highchair of the present invention further
comprises a tray 40 mounted onto at two handles 103 of the seat 10,
such that the baby sitting on the highchair can eat while sitting
on the highchair. In addition, a sitting portion of the seat 10
further comprises a flange 104 for preventing the baby from sliding
down from the highchair, and thus the footrest 30 and the flange
104 constitute a dual protection mechanism for preventing the baby
from sliding from the highchair.
[0021] In the aforementioned structure and implementation method,
the highchair of the present invention can be assembled and
disassembled easily and provide a convenient carry or
transportation. In addition, the seat 10 and the leg portion 20 can
be coupled more securely to enhance the safety of the
highchair.
