DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0023] Hereinafter, preferred embodiments of the present invention
will be described with reference to the accompanying drawings. The
matters defined in the description, such as the detailed
construction and elements, are nothing but specific details
provided to assist those of ordinary skill in the art in a
comprehensive understanding of the invention, and thus the present
invention is not limited thereto.
[0024] FIG. 1 is a perspective view illustrating a sectional shelf
according to a first embodiment of the present invention, and FIG.
2 is an exploded perspective view illustrating the sectional shelf
in FIG. 1.
[0025] The sectional shelf according to this embodiment includes,
as shown in FIGS. 1 and 2, rectangular shelves which are stacked in
four compartments, and four supports which are located at four
corners of the shelves. It would be understood to one skilled in
the art that the shape and number of the assembled shelves and the
number of the supports may be varied, if necessary.
[0026] Referring to FIGS. 1 and 2, the sectional shelf according to
this embodiment includes shelves 10 each having at least two
fastening parts 11 and stacked one by one to form desired
compartments, support members 20 located between the shelves 10 for
supporting the shelves 10, an upper coupling member 30 with one end
inserted into an upper end of each support member 20 and the other
end inserted into a lower end of each support member 20, and a
lower coupling member 40 with one end inserted into a lower end of
each support member 20 and the other end inserted into an upper end
of each support member 20.
[0027] The shelf 10 has an upper portion opened to easily store
articles and a lattice-like lower portion made of horizontal ribs
12 and vertical ribs 13 which are made of corrosion-proof metal,
such as stainless steel.
[0028] Also, the shelf 10 has an upper frame 14 and a lower frame
15 which are disposed on an edge of the shelf 10, and a support
frame 16 interposed between the upper frame 14 and the lower frame
15 for maintaining the whole shape of the shelf 10 and preventing
things from dropping from the shelf.
[0029] The fastening parts 11 installed to front and rear corners
of the shelf 10 is adapted to engage to the support member 20, and
is formed in a pipe with opened upper and lower portions.
[0030] When the shelves 10 are stacked in several shelf
compartments, as shown in FIGS. 1 and 2, the shape of the lowermost
shelf, the middle shelf, or the uppermost shelf may be changed.
[0031] The support member is interposed between the fastening part
of the shelf and the fastening part of a neighbor shelf, and is
made of a hollow pipe.
[0032] The upper coupling member 30 is to couple the support member
with the lower end of the fastening part of each shelf. The upper
coupling member 30 has a stop portion 41 formed on a middle portion
of an outer periphery of the upper coupling member. The stop
portion has a diameter larger than an inner diameter of the support
member 20 and fastening part 11, so as to prevent the upper
coupling member 30 from being fully inserted in the support member
20 and the fastening part 11.
[0033] Specifically, the upper coupling member 30 consists of an
upper coupling part 32 which is inserted in the fastening part 11
of the shelf upwardly positioned and a lower coupling part 33 which
is inserted in the support frame downwardly positioned, on the
basis of the stop portion.
[0034] Preferably, the diameter of the stop portion 31 is equal to
an outer diameter of the support member 20, so that the coupled
portion of the stop portion 31 and the support member 20 has a
smooth appearance even though the stop portion 31 is outwardly
exposed.
[0035] The upper coupling portion 32 is provided on an inner
periphery thereof with a threaded portion 32a which is threadedly
engaged with a threaded portion of the lower coupling member 40 of
the upper shelf.
[0036] The lower coupling member 40 is to couple the support member
20 with the upper end of the fastening part 11 of each shelf 20.
The lower coupling member 40 has an upper engaging portion 42 at an
upper end which is inserted in the support member 20 of the upper
shelf, a lower engaging portion 43 at a lower end which is inserted
in the fastening part 11 of the lower shelf, and a stop portion 41
formed on a middle portion of an outer periphery. The stop portion
has a diameter larger than an inner diameter of the support member
20 and fastening part 11, so as to prevent the lower coupling
member 40 from being fully inserted in the support member 20 and
the fastening part 11. Consequently, when the lower coupling member
40 is inserted between the support member 20 and the adjacent
support member 20, the stop portion 41 is outwardly exposed.
[0037] In this instance, like the stop portion 31 of the upper
coupling member 30, the diameter of the stop portion 41 is equal to
an outer diameter of the support member 20, so that the coupled
portion of the stop portion 41 and the support member 20 has a
smooth appearance when the support members 20 are coupled to each
other.
[0038] The lower engaging portion 43 is provided on a lower end
thereof with a threaded portion 43a which is threadedly engaged
with the threaded portion 32a of the upper coupling member 30 of
the lower shelf.
[0039] An upper end cover 50 is mounted on an upper end of each
fastening part 11 of the uppermost shelf. The upper end cover 50 is
provided on a lower portion thereof with a threaded portion 52
which is threadedly engaged with the threaded portion 32a of the
upper coupling member 30.
[0040] Preferably, the upper end cover 50 has a head 51 of a
diameter larger than the inner diameter of the fastening part 11
and equal to the outer diameter of the fastening part 11, thereby
preventing the upper end cover from being fully inserted in the
fastening part 11.
[0041] A lower end cover 60 is mounted on a lower end of each
fastening part 11 of the lowermost shelf. The lower end cover 60
has an inserting portion 61 which is inserted in the fastening part
11 of the lowermost shelf 10. The inserting portion has a stepped
stop portion 62 of a diameter larger than the inner diameter of the
fastening part 11, thereby preventing the lower end cover 60 from
being fully inserted in the fastening part 11.
[0042] In this instance, the inserting portion 61 and the stop
portion 62 are provided with threaded portions 61a and 62a which
are threadedly engaged with the threaded portion 43a of the lower
coupling member 40 and the threaded portion 72 of a base member
70.
[0043] The base member 70 is mounted on the lower end of the lower
end cover 60. The base member 70 has a body 71 of a diameter larger
than the lower end cover and a threaded portion 72 formed on an
upper end of the body 71.
[0044] The body 71 has a flat bottom surface to stably support the
shelf 10. Preferably, the body 71 is made of a synthetic rubber,
for example, so as to prevent slippage of the base member.
[0045] The threaded portion 72 is threadedly engaged with the
threaded portion 62a formed on the inner periphery of the stop
portion 62 of the lower end cover 60. Consequently, the sectional
shelf of the present invention can be stably positioned on an
uneven ground by rotating the threaded portion 72 of the base
member so as to adjust a height of the sectional shelf.
[0046] A process of assembling the sectional shelf according to
this embodiment of the present invention will now be described with
reference to FIGS. 1 and 2.
[0047] Since the assembling process is identical irrespective of
the number of the shelves to be stacked, the process of assembling
two shelves will now be described.
[0048] The lower end cover 60 is inserted in the lower end of the
fastening part 11 of the lower shelf, and the lower end cover 60 is
inserted in the lower end of the fastening part 11 and threadedly
engaged with the threaded portion 43a of the lower coupling member
40 of the upper shelf.
[0049] Then, the lower end of the support member 20 is inserted in
the upper end of the lower coupling member 40, and the lower end of
the upper coupling member 30 is inserted in the upper end of the
support member 20.
[0050] If the upper coupling member 30 is inserted in the upper end
of the support member 20, the threaded portion 32a of the upper
coupling member 30 is inserted in the fastening part 11 of the
upper shelf.
[0051] The upper end cover 50 is inserted in the upper end of the
fastening part of the upper shelf 11, and then, the threaded
portion 52 is engaged with the threaded portion 32a of the upper
coupling member 30 by rotating the upper end cover 50.
[0052] After the upper coupling member 30 and the lower coupling
member 40 are fixed to upper and lower ends of the support member
20, the support member 20 is fastened to the shelf 10.
[0053] FIGS. 3 and 4 illustrate a sectional shelf according to a
second embodiment of the present invention. The sectional shelf
according to this embodiment includes shelves 10 each having at
least two fastening parts 11 at and edge thereof and stacked one by
one to form desired shelf compartment, and support members 20
located between the shelves 10 for supporting the shelves 10, in
which a lower end of the support member 10 is inserted in an upper
end of the fastening part 11 and an upper end is inserted in a
lower end of the fastening part 11.
[0054] Explaining the sectional shelf shown in FIGS. 3 and 4, parts
which are identical to those shown in FIGS. 1 and 2 are shown by
corresponding reference numerals.
[0055] Since the construction of the shelf 10 in FIGS. 3 and 4 is
substantially similar to that shown in FIGS. 1 and 2, the shelf 10
will not be described herein.
[0056] The support member 20 is made of a hollow pipe, and is
located at four corners of the shelf, respectively, as shown in
FIGS. 1 and 2, but it may be easily modified by those skilled in
the art.
[0057] The support member 20 is provided on an outer periphery
thereof with upper and lower bosses 21 and 22 having a diameter
larger than an inner diameter of the fastening part 11 and spaced
apart from each other at a certain interval. An upper coupling part
23 which is engaged to the lower end of the fastening part 11 of
the shelf 10 is provided on the upper portion of the upper boss 21,
and a lower coupling part 24 which is engaged to the upper end of
the fastening part 11 of the shelf 10 is provided on the lower
portion of the lower boss 22.
[0058] The upper and lower bosses 21 and 22 are formed by
compressing the support member 20 in a longitudinal direction.
Preferably, the bosses 21 and 22 have a diameter equal to an outer
diameter of the fastening part 11.
[0059] The upper boss 22 is caught by the lower end of the
fastening part 11 of the upper shelf, while the lower boss 24 is
caught by the upper end of the fastening part 11 of the lower
shelf.
[0060] An upper end cover 50' is mounted on an upper end of each
fastening part 11 of the uppermost shelf. The upper end cover 50'
has a head 51' of a diameter larger than the inner diameter of the
fastening part 11 and equal to the outer diameter of the fastening
part 11, thereby preventing the upper end cover 50' from being
fully inserted in the fastening part 11.
[0061] The construction of the upper end cover shown in FIGS. 3 and
4 is slightly different from that of the upper end cover shown in
FIGS. 1 and 2, in which a threaded portion is not formed on the
lower portion 52' of the upper end cover 50'.
[0062] A support leg 80 is mounted on a lower end of each fastening
part 11 of the lowermost shelf. The support leg 80 is provided at a
middle portion thereof with an annular boss 81 for catching the
fastening part 11, thereby preventing the support leg 80 from being
fully inserted in the fastening part 11.
[0063] The lower end of the support leg 80 is coupled to a slippage
prevention member 84 made of a synthetic rubber, so as to prevent
slippage of the support leg.
[0064] Reference numerals 82 and 83 indicate an upper engaging part
inserted in the lower end of the fastening part of the lowermost of
the shelf and a lower engaging part inserted in the slippage
prevention member, respectively.
[0065] FIGS. 5 and 6 illustrate a sectional shelf according to a
third embodiment of the present invention. The sectional shelf
according to this embodiment includes shelves 10 each having at
least two fastening parts 11 at an edge thereof and stacked one by
one to form desired shelf compartment, and support members 20
located between the shelves 10 for supporting the shelves 10, in
which a lower end of the support member 10 is inserted in an upper
end of the fastening part 11 and an upper end is inserted in a
lower end of the fastening part 11.
[0066] Explaining the sectional shelf shown in FIGS. 5 and 6, parts
which are identical to those shown in FIGS. 1 to 4 are shown by
corresponding reference numerals.
[0067] Since the construction of the shelf 10 in FIGS. 3 and 4 is
substantially similar to that shown in FIGS. 1 and 2, the shelf 10
will not be described herein.
[0068] The support member 20 is made of a hollow pipe, and is
located at four corners of the shelf, respectively, but it may be
easily modified by those skilled in the art.
[0069] The support member 20 is provided on an outer periphery
thereof with upper and lower bosses 21 and 22 having a diameter
larger than an inner diameter of the fastening part 11 and spaced
apart from each other at a certain interval. The upper and lower
bosses 21 and 22 are formed by compressing the support member 20 in
a longitudinal direction. Preferably, the bosses 21 and 22 have a
diameter equal to an outer diameter of the fastening part 11.
[0070] The upper boss 22 is caught by the lower end of the
fastening part 11 of the upper shelf, while the lower boss 24 is
caught by the upper end of the fastening part 11 of the lower
shelf.
[0071] An upper coupling member 30' is inserted and engaged to the
upper end of each support member 20, and a lower coupling member
40' is inserted and engaged to the lower end of each support member
20.
[0072] The upper coupling member 30' has an engaging portion 31' of
an outer diameter corresponding to the inner diameter of the

threaded portion 31a' on an inner periphery thereof. The engaging
portion 31' is provided on an upper end thereof with a flange 32'
which protrudes outwardly from the periphery thereof at a certain
length, so as to prevent the upper coupling member 30' from being
fully inserted in the support member 20. Preferably, the flange 32'
has a diameter equal to the outer diameter of the support member
20.
[0073] Similarly, the lower coupling member 40' has an engaging
portion 41' of an outer diameter corresponding to the inner
diameter of the support member 20, and the engaging portion 41' is
provided with a threaded portion 41a' on an inner periphery
thereof. The engaging portion 41' is provided on an upper end
thereof with a flange 42' which protrudes outwardly from the

carried out by coupling the support member 20 with the support
members 20 of neighbor shelves.
[0076] Specifically, the upper coupling member 30' engaged to the
upper portion of each support member 20 is threadedly engaged with
the lower coupling member 40' of the support member passing through
the fastening part 11 of the upper shelf 10, while the lower
coupling member 40' engaged to the lower portion of each support
member 20 is threadedly engaged with the upper coupling member 30'
of the support member passing through the fastening part 11 of the
lower shelf 10, thereby assembling the shelves.
[0077] Finally, the assembly of the shelves is completed by
threadedly engaging the upper end cover 50 and the support leg 80
with the fastening parts of the uppermost and lowermost shelves,
respectively.
[0078] FIG. 7 illustrates a sectional shelf according to a fourth
embodiment of the present invention. The sectional shelf according
to this embodiment includes shelves 10 each having at least two
fastening parts 11 at an edge thereof and stacked one by one to
form desired shelf compartments, and support members 20 located
between the shelves 10 for supporting the shelves 10, in which a
lower end of the support member 10 is inserted in an upper end of
the fastening part 11 and an upper end is inserted in a lower end
of the fastening part 11, which is substantially similar to the
first to third embodiments.
[0079] In this embodiment, a lower end cover 60 is engaged to the
fastening part 11 of the lowermost shelf 10, like the first
embodiment, and a caster assembly 90 is coupled to the lower end of
the lower end cover 60.
[0080] The caster assembly 90 includes a caster 91 rotatably
engaged to a caster bracket 92 by a rotation shaft (not shown) and
a threaded part 93 protruding upwardly from the caster bracket 92.
The locking portion 62 of the lower end cover 60 is provided with a
threaded portion 62a which is threadedly engaged with the threaded
part 93 of the caster bracket 92.
[0081] Consequently, a user may selectively mount or dismount the
caster assembly on the lower end cover 80, if necessary.
[0082] Preferably, a stopper 94 for restraining rotation of the
caster 91 is hinged to one portion of the caster bracket 92 so as
to fix the position of the sectional shelf.
[0083] In this instance, the stopper 94 is adapted so that one end
comes into contact with the ground to fix the sectional shelf.
Alternatively, the stopper 94 is adapted so that it directly
contacts the caster 91 to prevent rotation of the caster 91.
[0084] The stopper 94 may be wholly or partially made of a
synthetic rubber, for example, so as to increase a frictional force
between the stopper 94 and the ground.
[0085] Although this embodiment explains the case in that the
caster assembly is coupled to the lower end of the lower end cover
shown in the first or third embodiment, the caster assembly may be
coupled to a threaded groove which is formed on the lower end of
the support leg 80 of the second embodiment.
[0086] With the above description, the sectional shelf of the
present invention can permit easy assembling and disassembling of a
plurality of shelves, and stably maintain the shape of the shelves
assembled by support members and/or coupling members.
[0087] Although preferred embodiments of the present invention have
been described for illustrative purposes, those skilled in the art
will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and
spirit of the invention as disclosed in the accompanying
claims.
