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 ArtTo 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.
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.
To overcome the shortcomings, the present invention tends to provide a rack assembly to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTIONThe main objective of the invention is to provide a rack assembly having sub-rack(s) being adjustable in amount and position.
The rack assembly has two side racks, two rails, and at least one sub-rack.
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.
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.

With reference to
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.
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.
With reference to
With reference to
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
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.
Claims
