The present device generally relates to a support member for use in a shelving system. In particular, the support member includes ends thereof that are reinforced for retaining the support member in the related system without the use of welding.
Rack-type shelving systems are used in heavy-duty storage scenarios. These types of shelving systems typically use elongated metal components that are assembled together to give the resultant shelving units their shape, mechanical support, and to position the associated shelves. Typically, these components are assembled at 90° angles that extend relative to each other in various directions, depending on the particular component. Variations of this shelving include components that can be assembled together without separate fasteners or tools by use of interlocking tabs, slots, and the like. Further, the components of these types of shelving are often fabricated from bent sheet material or various extrusions, to give the desired strength at a reduced weight and cost compared to solid or cast materials.
Because of the structure of the assembled shelving units, in which various components are relied upon in the assembly for providing strength along the various axes, relatively thin materials can be used with profiles that generally resist bending along the lengths of the components. However, in the areas where the components are assembled together, such thin material may not be able to withstand the loads imparted thereon due to shelf loading or the like. Accordingly, coupling ends of these components, particularly longer shelving support members or beams, are often made of thicker material that is welded onto the ends of the component. The additional material and components associated with this construction can add to manufacturing time and overall cost. Accordingly, further advances may be desired.
SUMMARYAccording to an aspect of the present disclosure, a shelving support member includes a unitary member of a bent sheet material and defining a support portion extending along an axis to a first end and a retention portion disposed at the first end of the support portion. The retention portion defines a base extending congruently with the support portion along the axis to a first fold in the member. A reinforcement portion extends from the first fold toward the first end of the support portion in contact with the base. A first punched area is defined in an aligned manner through both the base and the reinforcement portion of the retention portion.
According to another aspect of the present disclosure, a shelving system includes a first vertical member and a shelf support beam. The shelf support beam includes a unitary member defining a support portion including sheet material extending along an axis from a first end and a retention portion disposed at the end of the support portion. The retention portion defines a base extending congruently with the support portion along the axis to a first fold in the member. A reinforcement portion extends oppositely from the base along the axis in contact with the base. A first punched area is defined in an aligned manner through both the base and the reinforcement member of the retention portion. The shelf support beam is coupleable with the first vertical member at the retention portion thereof such that the shelf support beam extends perpendicularly from the first vertical member.
According to another aspect of the present disclosure, a method for making a shelving support member includes bending an extension tab extending from a support portion along an axis to a first end. The extension tab initially extends along the axis beyond the first end of the support portion and is bent to form a first fold separating the extension tab into a base extending congruently with the support portion and a reinforcement portion extending oppositely from the base along the axis in contact with the base. The method further includes forming a first punched area in an aligned manner through both the base and the reinforcement member.
These and other features, advantages, and objects of the present device will be further understood and appreciated by those skilled in the art upon studying the following specification, claims, and appended drawings.

As discussed above, support member 10 comprises a bent or otherwise formed structure of metal (such as steel, for example) sheet material. Accordingly, in a method of fabricating support member 10, a blank of sheet material of metal having appropriate properties, and of appropriate size for the particular support member 10 being fabricated, can be cut into a shape that can be bent and folded in the form shown in
Subsequently, the material can be bent to form upper flange 50 and lower flange 52 of support portion 14, including by bending the designated area corresponding thereto with respect to vertical portion 48 such that upper flange 50 and lower flange 52 extend inwardly away therefrom at the desired angle (e.g., 90°). Additionally, if desired, shelf recess 54 can be bent into upper flange 50. Subsequently, retention portion 20 can be formed by bending the cut material along the desired area of first fold 24 to define base 22 and reinforcement portion 26. Subsequently, the above-described punched area 28 can be formed through retention portion 20 by stamping or punching of base 22 and reinforcement portion 26 in a single operation, according to the various techniques described above. Coupling tab 78 can be defined within punched area 28 by forming folded edge 80 between cut edge 74 and 76 by bending, stamping, or the like, with coupling tab 78 being further shaped by bending or folding. In one embodiment, punched area 28 and coupling tab 78 can be simultaneously formed by a combined punching and stamping operation in which a single tool and die arrangement is used to form cut edges 72, 74, and 76 in a single operation in which the portion of retention portion 20 defined within cut edges 72, 74, and 76 is then bent to define folded edge 80 and the desired shape of coupling tab 78. Support members 11 can be fabricated in a similar manner, with an additional fold 25a being incorporated between respective portions 23a and 23b.

Support member 110 can be fabricated in a manner generally similar to that used in fabricating support member 10, described above with respect to
After the desired forming of the sheet material has been completed to form the unitary support member 110, first and second punched areas 128 and 138 can be formed through retention portion 120, including by stamping or punching holes or the like through both base 122 and reinforcement portion 126, simultaneously. Alternatively, punched areas 128 can be formed by cutting holes through retention portion 120 and reinforcement portion 26, including by laser cutting or the like. Subsequently, first rivet 130 and second rivet 140 can be coupled, respectively, with first punched area 128 and second punched area 138. Variations of support member 110 including additional or fewer rivets 130 can be fabricated by a similar process with the desired number of punched areas and rivets being formed in and assembled with support member 110.

Tab slot 268 can be similarly configured with the respective upper 268a and lower 268b portions receiving retention tab 266 therethrough during movement of support member 210 in a horizontal direction toward vertical member 232. Further, lower portion 168b can be narrower such that a portion of vertical member 232 is captured between respective portions of retention tabs 266a and 266b and reinforcement portion 226 after movement of support member 210 in the vertical direction 270. In this arrangement, the narrower lower portion 268b can be horizontally offset with respect to the upper portion, as opposed to being centered in the case of slot 136, discussed above.
A method for fabricating support member can be generally similar to the above-described method of fabricating support member 10 and support member 110. However, retention tabs 266a and 266b can be coupled with retention portion 220 as a separate element with the use of mechanical fasteners, adhesives, welding, or the like. Alternatively, first and second punched areas 228 and 238 can be formed using a three-sided punch or cut through both base 222 and reinforcement portion 226 with retention tabs 266a and 266b being bent from respective portions of base 222 and reinforcement portion 226 and being defined within punched areas 228 and 238 in a similar manner to that which is discussed above with respect to coupling tab 78.
