Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a rack assembly, and more
particularly to a rack assembly having at least one sub-rack that
is detachable from the rack assembly.
2. Description of Related Art
[0002] To display goods to customers in a store or a hypermarket,
rack assemblies are applied. A conventional rack assembly
substantially comprises a rack frame composed of multiple rods and
multiple supporting members mounted securely on the rack frame.
Accordingly, the goods can be put on and supported by the
supporting members for customers to purchase.
[0003] However, the supporting members are securely mounted on the
rack frame, so the supporting members cannot be detached from the
rack frame or the positions of the supporting members cannot be
adjusted relative to the rack frame. In addition, another
conventional rack assembly has at least one sub-rack that is
adjustable in position and in amount. However, to combine the
sub-rack with the conventional rack assembly has to follow a
predetermined direction, so the use of the conventional rack
assembly is still inconvenient.
[0004] To overcome the shortcomings, the present invention tends to
provide a rack assembly to mitigate or obviate the aforementioned
problems.
SUMMARY OF THE INVENTION
[0005] The main objective of the invention is to provide a rack
assembly having sub-rack(s) being adjustable in amount and
position.
[0006] The rack assembly has two side racks, two rails, and at
least one sub-rack.
[0007] The side racks are spaced from each other. The rails are
mounted between and connected with the side racks, are parallel
with each other, are located at a same height, and include a front
rail and a rear rail. Each rail has a U-section to form an opening
in a bottom of the rail. The at least one sub-rack is disposed
between the side racks and is slidable along the rails. Each one of
the at least one sub-rack has a rack frame, a connection rod, and
at least one supporting member. The rack frame is composed of
multiple longitudinal rods including at least one front rod and at
least one rear rod corresponding in position respectively to the
front rail and the rear rail. Each one of the at least one front
rod has an extension rod mounted retractably on a top of the front
rod and having a top and a front wheel mounted rotatably on the top
of the extension rod. The connection rod is connected to the
extension rod of each one of the at least one front rod. The at
least one supporting member is mounted on the rack frame.
[0008] Other objects, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0016] With reference to FIG. 1, a rack assembly in accordance with
the present invention comprises two side racks 10, two rails 20,22
and at least one sub-rack 30. The side racks 10 are spaced from
each other. Each side rack 10 comprises a rack frame 12 composed of
multiple longitudinal rods 122 and at least one supporting member
14 mounted securely on the rack frame 12. Each supporting member 14
may be a plate or a bracket to support objects on the supporting
member 14. The rails 20,22 are mounted between and connected with
the side racks 10, are parallel with each other, are located at a
same height, and include a front rail 20 and a rear rail 22.With
reference further to FIG. 7, each rail 20,22 has a U-section to
form an opening 202,222 in a bottom of the rail 20,22. Each rail
20, 22 comprises a bottom panel 21, an outer panel 212, and an
inner panel 214. The outer panel 212 and the inner panel 214 are
respectively formed on and extend downwardly from two sides of the
bottom panel 21. The inner panels 214 of the two rails 20, 22 face
each other. The inner panel 214 of each rail 20, 22 has a downward
extension length larger than a downward extension length of the
outer panel 212 of the rail 20,22.
[0017] With reference to FIGS. 2 to 4, the at least one sub-rack 30
is disposed between the side racks 10 and is slidable along the
rails 20,22. In the embodiment as shown in FIG. 1, two sub-racks 30
are implemented. Each sub-rack 30 comprises a rack frame 32, a
connection rod 37, and at least one supporting member 31. The rack
frame 32 is composed of multiple longitudinal rods 33,34. The rods
33,34 include at least one front rod 33 and at least one rear rod
34 corresponding in position respectively to the front rail 20 and
the rear rail 22. Preferably, two front rods 33 and two rear rods
34 are implemented. Each front rod 33 has an extension rod 332
mounted retractably on a top of the front rod 33 and having a top
and a front wheel 334 mounted rotatably on the top of the extension
rod 332. Consequently, each front rod 33 has a total length larger
than a total length of each rear rod 34. In addition, each front
rod 33 has a spring 336 mounted in the front rod 33 and abutting a
bottom of the extension rod 332 to push the extension rod 332
upward and to hold the front wheel 334 in the front rail 20.
Furthermore, each rod 33,34 has a bottom and a rotating wheel 36
mounted on the bottom of the rod 33,34.
[0018] The connection rod 37 is connected to the extension rods 332
of the front rods 33. In addition, each sub-rack 30 further
comprises a pulling rod 372 mounted on the connection rod 37 of the
sub-rack 30. Accordingly, the connection rod 37 can be pulled
downward by pulling the pulling rod 372, and the extension rods 332
can be retracted into the front rods 33 and the front wheels 334
will escape from the front rail 20 via the opening 202 in the front
rail 20.
[0019] The at least one supporting member 31 is mounted securely on
the rack frame 32. Each supporting member 31 may be a plate or a
bracket to support objects on the supporting member 31.
[0020] With reference to FIGS. 1, 3, and 4, when in use, front
wheels 334 on the front rod 33 of each sub rack 30 are held in a
channel defined between the front panel 212 and the rear panel 214
of the front rail 20 and rotatably abut the inner surface of the
inner panel 314 of the front rail 20. Accordingly, the sub racks 30
are moveable along the rails 20, 22, and the positions of the
sub-racks 30 are adjustable. Therefore, the rack assembly in
accordance with the present invention is versatile in use.
[0021] With reference to FIGS. 5 to 7, when the connection rod 37
or the pulling rod 372 of one of the sub-racks 30 is pulled
downward, the extension rods 332 of said one of the sub-racks 30
will be retracted into the front rods 33 and the front wheels 334
will escape from the front rail 20 via the opening 202 of the front
rail 20. Accordingly, the sub-rack 30 can be pushed to move forward
relative to the side racks 10 even to leave the position between
the side racks 10. Consequently, the sub-rack 30 can be applied to
support objects individually. Therefore, the amounts and the
positions of the sub-racks 30 between the side racks 10 can be
changed to fit with different user demands, such that the rack
assembly is versatile in use.
[0022] Additionally, because the rails 20, 22 are located at the
same height, and the total length of the front rods 33 of each
sub-rack 30 is larger than the total length of the rear rod 34 of
the sub-rack 30, the sub-racks 30 can be put into a position
between the side racks 10 from the front rail 20 as shown in FIG.
7. The sub-racks 30 may be put into a position between the side
racks 10 from the rear rail 22 as shown in FIG. 8. Therefore, the
sub-racks 30 can be combined with the side racks 10 along different
directions to fit with different use demands Thus, the rack
assembly in accordance with the present invention is versatile in
use.
[0023] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, the disclosure is illustrative only, and changes may be
made in detail, especially in matters of shape, size, and
arrangement of parts within the principles of the invention to the
full extent indicated by the broad general meaning of the terms in
which the appended claims are expressed.
