STOP WALL STRUCTURE FOR REMOVABLY MOUNTING TO A METAL-WIRE SHELF
A stop wall structure includes a front stop wall and two side stop walls for removably mounting to a front edge and two lateral edges of a metal-wire shelf for a sectional rack. The front stop wall is formed along a lower edge with a tongue portion and a plurality of clamping member spaced behind the tongue portion, so that a retaining space is formed between the tongue portion and the clamping members for engaging with a transverse front metal-bar set of the metal-wire shelf therein. The side stop walls each are provided along a lower edge with a plurality of C-shaped clamping members for each receiving and holding a transverse metal bar of the metal-wire shelf therein.

The present invention relates to a stop wall structure for removably mounting to a front and two lateral sides of a metal-wire shelf for, for example, a sectional rack, so that articles positioned on the metal-wire shelf are protected against undesirable falling therefrom.
BACKGROUND OF THE INVENTIONIn a sectional metal rack, metal-wire shelves are often used to hold different articles thereon. As can be seen from
The metal-shelf 10 is formed by welding a plurality of longitudinally extended metal wires 11 to a plurality of transversely extended intermediate metal bars 12, a front metal-bar set 13, and a rear metal-bar set 14, so that the metal wires 11 and the metal bars 12, 13, 14 intersect at a right angle. The front metal-bar set 13 includes an upper front and a lower front metal bar 131, 132, and the rear metal-bar set 14 includes an upper rear and a lower rear metal bar 141, 142. The metal-wire shelf 10 has four completely open sides, and articles positioned thereon are subject to undesirable falling therefrom. As can be seen in
If metal wires and metal bars are used to directly form upright stop walls (not shown) at four sides of the metal-wire shelf 10, these stop walls would inevitably increase the manufacturing cost and the overall weight of the metal-wire shelf to thereby reduce the competing ability of the metal rack in the market. Further, the metal-wire shelf 10 with the upright stop walls formed with the metal wires and bars thereof tends to have a large volume that causes difficulty in packing the metal-wire shelf and increases the warehousing and transporting costs thereof to further reduce the competing ability of the sectional rack using such metal-wire shelf.
It is therefore tried by the inventor to develop an improved stop wall structure for removably mounting to a metal-wire shelf, so that articles positioned on the metal-wire shelf are protected against undesirable falling therefrom, and the metal-wire shelf can have wider applications.
SUMMARY OF THE INVENTIONA primary object of the present invention is to provide a stop wall structure for mounting to a front and two lateral edges of a metal-wire shelf for a sectional rack, for example, so that articles positioned on the metal-wire shelf are protected against falling therefrom.
Another object of the present invention is to provide a stop wall structure for removably mounting to a metal-wire shelf, so that the stop wall structure does not increase the packing, warehousing and transporting costs of a sectional rack using the metal-wire shelf.
To achieve the above and other objects, the stop wall structure according to the present invention includes a front stop wall and two side stop walls for removably mounting to a front edge and two lateral edges, respectively, of a metal-wire shelf for a sectional rack, for example.
The front stop wall is formed along a lower edge thereof with a tongue portion and a plurality of clamping member inward and downward extended from a rear side of the tongue portion, so that a retaining space is formed between the tongue portion and the clamping members for firmly engaging with a transverse front metal-bar set of the metal-wire shelf. Each of the clamping members is provided at a left side with a leftward open slot for receiving a longitudinal metal wire of the metal-wire shelf therein.
The side stop walls each are provided along a lower edge with a plurality of C-shaped clamping members for each receiving and holding a transverse metal bar of the metal-wire shelf therein, so that the side stop walls are assembled to two lateral edges of the metal-wire shelf.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
Please refer to
The metal-wire shelf 10 is supported on the sectional rack via two supporting brackets 40 that are separately hooked to two spaced vertical posts 50 of the sectional rack. The vertical posts 50 are provided on respective front faces with two vertical rows of hanging holes 51, and the two supporting brackets 40 are inserted into and thereby hooked to two selected corresponding hanging holes 51 on the two vertical posts 50. Since the supporting of metal-wire shelf 10 on the vertical posts 50 via the supporting brackets 40 and the hanging holes 51 is a known skill, it is not discussed in details herein.

Each of the first and second C-shaped clamping members 31, 32 is provided at a lower portion with a downward open slot 311, 321, which is sized to engage with one longitudinal metal wire 11 of the metal-wire shelf 10. To mount the side stop wall 30 to the lateral edge of the metal-wire shelf 10, first align the open slots 311, 321 on the first and second C-shaped clamping members 31, 32 with one of the longitudinal metal wires 11 on the metal-wire shelf 10, so that the metal wire 11 can be guided into the open slots 311, 321. Then, move the side stop wall 30 toward the front edge of the metal-wire shelf 10 to align the first and the second clamping members 31, 32 with the front metal-bar set 13 and the intermediate metal bars 12, respectively, allowing the front metal-bar set 13 and the intermediate metal bars 12 to correspondingly move into and be held in the first and second C-shaped clamping members 31, 32. At this point, the side stop wall 30 is bound by the longitudinal metal wire 11 and can no longer move sidewardly relative to the metal-wire shelf 10.
As having been mentioned above, the front metal-bar set 13 includes an upper front metal bar 131 and a lower front metal bar 132; and front ends of the longitudinal metal wires 11 are welded to and between the upper and lower front metal bars 131, 132. The first C-shaped clamping member 31 located at a most lower front end of the side stop wall 30 is used to clamp the upper front metal bar 131 therein. Since the upper front metal bar 131 is located higher than the intermediate metal bars 12, the first C-shaped clamping member 31 is provided at a position higher than the second C-shaped clamping members 32.
The side stop wall 30 is further provided on a front end face near an upper end thereof with a recess 33. And, as can be seen in

With the front stop wall 20 being formed from two detachably connected half-plates 20a, the front stop wall 20 provides more flexibility in the application thereof. For example, the metal-wire shelf 10 can have only one of the half-plates 20a mounted to the front edge thereof while the two side stop walls 30 are separately mounted on the metal-wire shelf 10 to connect to two lateral edges of the half-plate 20a, as shown in
The stop wall structure of the present invention can be mounted to selected positions on a metal-wire shelf 10, so that the metal-wire shelf 10 has walls to provide better function for holding things thereon. Since the stop wall structure is removably mounted to the metal-wire shelf 10, it would not increase the overall volume and accordingly the warehousing and transporting costs of the sectional rack using the metal-wire shelf with the stop wall structure of the present invention. Therefore, the stop wall structure for metal-wire shelf according to the present invention is convenient and practical for use and will no doubt meet consumers' demands.
