FIELD OF THE INVENTION
The present invention relates generally to bracket and hook accessories configured to be detachably connected to a shelving unit and support a variety of different articles.
BACKGROUND
Storage racks and shelving units are commonly used to store a variety of different articles, such as tools and equipment in a garage (e.g., drills, brooms, shovels, extension cords, etc.), in an organized and readily accessible manner. Typical storage racks include left and right end support units and front and rear cross beams extending between the end support units. Together, corresponding front and rear cross beams extending between the end support units define a frame configured to support a shelf for storing various articles. Typically, each end support unit includes front and rear vertical support members and cross braces, both horizontal and diagonal, interconnecting the front and rear vertical support members.
One common type of storage rack known in the art is a “boltless” rack, in which at least some of the members of the rack are configured to be assembled without the use of permanent mechanical fasteners. In some conventional boltless racks, the members of the end support units are permanently coupled together, such as by welding or riveting, and the cross beams are detachably connected to the vertical support members of the end support units. Typically, the vertical support posts include a series of apertures, such as wedge-shaped slots or keyhole-shaped openings, configured to detachably receive interconnecting members, such as rivets or lances, on opposite ends of the cross beams. Accordingly, boltless racks are configured to permit easy assembly and disassembly of the storage rack or shelving unit without the use of tools, and to permit compact and economical shipment of the unit. An example of a boltless shelving unit is shown and described in U.S. patent application Ser. No. 13/360,543, entitled “Modular Rack Assembly,” the entire contents of which are hereby incorporated by reference.
The storage capacity of such conventional storage racks and shelving units, however, is limited by the number of shelves and their surface area. Practical considerations, such as the size of the user's workspace, may restrict the user from using a storage rack or shelving unit having larger shelves or a greater number of shelves. Additionally, it may be cumbersome to place certain articles (e.g., brooms, shovels, etc.) on a shelf and certain articles may not be readily accessible once stacked on a shelf. Accordingly, the bracket and hook accessories of the present invention are configured to be releasably attached to the frame of existing boltless storage racks and shelving units, thereby increasing the storage capacity of existing storage racks and shelving units. Additionally, the bracket and hook accessories of the present invention are repositionable along the frame of the storage rack and shelving units, thereby accommodating a variety of articles having different shapes and sizes.

DETAILED DESCRIPTION
The present invention relates generally to support bracketry, and more particularly to brackets and hooks configured to be detachably connected to a boltless shelving unit. The brackets and hooks are configured to support a variety of difficult articles, such as brooms, shovels, and other tools. The brackets and hooks of the present invention are configured to provide a system for storing a variety of different articles in an organized and readily accessible manner. The brackets and hooks of the present invention are also configured to increase the storage capacity of existing storage racks and shelving units.
With reference to FIG. 1, a boltless shelving unit 10 is illustrated having several different embodiments of brackets and hooks detachably connected thereto, each of which are described in more detail below. In the illustrated embodiment of FIG. 1, the boltless shelving unit 10 includes left and right end support units 11, 12, respectively, interconnected by front and rear crossbeams 13, 14, respectively. Each end support unit 11, 12 includes front and rear vertical support posts 15, 16, respectively, upper and lower horizontal braces 17, 18, respectively, and a diagonal brace 19. Ends of the upper braces 17 are coupled to upper ends of the vertical support posts 15, 16 and ends of the lower braces 18 are coupled to lower ends of the vertical support posts 15, 16. Ends of the diagonal braces 19 are coupled to intermediate portions of the vertical posts 15, 16 between the upper and lower ends of the vertical support posts 15, 16. In an alternate embodiment, the ends of the diagonal braces 19 may be secured to upper and lower ends of the vertical support posts 15, 16 (e.g., one end of the diagonal brace 19 may be coupled to the upper end of the rear vertical support post 16 and the other end of the diagonal brace 19 may be coupled to the lower end of the front vertical support post 15). The upper, lower, and diagonal braces 17, 18, 19 may be coupled to the vertical support posts 15, 16 by any suitable means, such as mechanical fastening or welding.
With continued reference to the embodiment illustrated in FIG. 1, each of the vertical support posts 15, 16 is a beam having an L-shaped transverse cross-section. It will be appreciated, however, that the vertical support posts 15, 16 may have any other suitable shape, such as a U-shaped or Z-shaped transverse cross-section. Additionally, in the illustrated embodiment, each of the vertical support posts 15, 16 includes a plurality of keyhole-shaped openings 20 arranged in two columns. As used herein, the term “plurality” shall mean two or more. Each of the keyhole-shaped openings 20 includes a relatively larger upper circular opening 21 and a relatively smaller circular opening 22 extending downward from a lower end of the larger opening 21. As described in detail below, embodiments of the brackets and hooks of the present invention are configured to be detachably connected to the keyhole openings 20 in the vertical support posts 15, 16.
Still referring to FIG. 1, opposite ends of the front crossbeams 13 are boltlessly coupled to the front vertical support posts 15 and ends of the rear crossbeams 14 are boltless coupled to the rear vertical support posts 16. It will be appreciated that the shelving unit 10 may include any suitable number of crossbeams 13, 14, such as between two and ten. Additionally, the crossbeams 13, 14 may be positioned at any suitable elevation along the vertical support posts 15, 16 depending upon the locations of the keyhole-shaped openings 20 in the vertical support posts 15, 16. In the illustrated embodiment, the crossbeams 13, 14 have an omega-shaped transverse cross-section. The crossbeams 13, 14 each include a pair of spaced apart upper and lower vertical legs 23, 24, respectively. In the illustrated embodiment, opposite ends of the upper and lower vertical legs 23, 24 of each crossbeam 13, 14 include interlocking members 25 configured to releasably engage the keyhole-shaped openings 20 in the vertical support posts 15, 16. The crossbeams 13, 14 each also include an upper horizontal flange 26 extending inward from a lower end of the upper vertical leg 23, a lower horizontal flange 27 extending inward from an upper end of the lower vertical leg 24, and a vertical flange 28 extending between inner ends of the upper and lower horizontal flanges 26, 27. Together, the inwardly extending upper horizontal flanges 26 on the crossbeams 13, 14 define a frame 29 configured to support a shelf panel 30 or other planar support member. As described in detail below, embodiments of the brackets and hooks of the present invention are configured to be detachably connected to the crossbeams 13, 14 and slidably positionable along the upper legs 23 of the crossbeams 13, 14 into any desired lateral position along the boltless shelving unit 10.
With reference now to FIGS. 2A and 2B, an embodiment of a bracket 35 configured to be detachably connected to the shelving unit 10 is illustrated. The bracket 35 is configured to be positionable along both the vertical support posts 15, 16 and the crossbeams 13, 14 of the shelving unit 10. As will be described in more detail below, the bracket 35 is configured to be coupled to various hooks configured to releasably support one or more articles, such as shovels, brooms, or other tools. In the illustrated embodiment, the bracket 35 includes a body portion 36 having a front surface 37 and a rear surface 38 opposite the front surface 37. The rear surface 38 of the bracket 35 is configured to abut a portion of the boltless shelving unit 10 (e.g., the rear surface 38 of the bracket 35 is configured to abut a portion of the vertical support posts 15, 16, as shown in FIG. 1). In the illustrated embodiment, the body portion 36 of the bracket 35 is generally rectangular, although it will be appreciated that the body portion 36 of the bracket 35 may have any other suitable shape, such as circular or square, and still fall within the scope and spirit of the present invention. The bracket 35 also includes a plurality of narrow ridges 39 projecting forward from the front surface 37 of the bracket 35. In one embodiment, the plurality of narrow ridges 39 includes a first set 40 of spaced apart narrow ridges 39 (e.g., three ridges 39 arranged in a first column) and a second set 41 of spaced apart narrow ridges 39 (e.g., three ridges 39 arranged in a second column), wherein the first set 40 of narrow ridges 39 at least partially overlaps the second set 41 of narrow ridges 39. It will be appreciated, however, that the bracket 35 may have any other suitable orientation and number of narrow ridges 39 and still fall within the scope and spirit of the present invention. The plurality of narrow ridges 39 are configured to increase the structural rigidity and load-bearing capacity of the bracket 35. Additionally, the plurality of narrow ridges 39 are configured to improve the weld securing the bracket 35 to the various hooks described below. Moreover, depending upon the manufacturing method of the bracket 35 (e.g., stamping or pressing), the bracket 35 may also include a plurality of recesses 42 in the rear surface 38 that correspond to the narrow ridges 39 on the front surface 37. In an alternate embodiment, the bracket 35 may be provided without the plurality of narrow ridges 39.
With reference now to FIGS. 2B and 2C, the bracket 35 also includes at least one interlocking member configured to detachably engage the keyhole-shaped openings 20 in the vertical support posts 15, 16 of the shelving unit 10. In the illustrated embodiment, the bracket 35 includes upper and lower interlocking members 43, 44, respectively, although the bracket 35 may include any other suitable number of interlocking members 43, 44, such as between one and four, depending upon the desired load-bearing capacity of the bracket 35 and the article(s) the bracket 35 is configured to support. The spacing between the interlocking members 43, 44 on the bracket 35 corresponds to the spacing between the keyhole-shaped openings 20 in the shelving unit 10 (i.e., the interlocking members 43, 44 on the brackets 35 are spaced to align with the keyhole openings 20 in the shelving unit 10). In the illustrated embodiment, the interlocking members 43, 44 are rivets having a shaft portion 45 projecting rearward from the rear surface 38 of the bracket 35. The shaft portion 45 includes an interconnected end 46 coupled to the rear surface 38 of the bracket 35 and a free end 47 opposite the interconnected end 46. The interlocking members 43, 44 also include a head portion 48 coupled to the free end 47 of the shaft portion 45. In the illustrated embodiment, the head portions 48 of the interlocking members 43, 44 each have an outer diameter larger than the outer diameter of the shaft portion 45. Additionally, it will be appreciated that the outer diameter of the head portions 48 is smaller than the larger circular opening 21 in the keyhole openings 20 in the vertical support posts 15, 16 such that the head portions 48 of the interlocking members 43, 44 may be inserted in the keyhole openings 20. Moreover, the outer diameter of the shaft portion 45 is smaller than the smaller circular opening 22 in the keyhole openings 20 such that the interlocking members 43, 44 can be selectively slid down into small circular openings 22, and the outer diameter of the head portion 48 is larger than the smaller opening portion 22 of the keyhole openings 20 such that the interlocking members 43, 44 are retained in the keyhole openings 20 in the vertical support posts 15, 16.
Still referring to the embodiment depicted in FIGS. 2A-2C, the bracket 35 also includes a tab 50 projecting upward from an upper edge 51 of the rectangular body portion 36. The tab 50 is co-planar with the body portion 36 of the bracket 35 and is also centered along a longitudinal centerline of the body portion 36. In the illustrated embodiment, the tab 50 supports the upper interlocking member 43 (i.e., the shaft portion 45 of the upper interlocking member 43 projects rearward from the rear surface 38 of the tab 50). In the illustrated embodiment, the tab 50 is generally rectangular with rounded upper corners 52, although the tab 50 may have any other suitable shape (e.g., triangular, semi-circular, etc.) and still fall within the scope and spirit of the present invention. The significance of the tab 50 and the position of the upper interlocking member 43 on the tab 50 are described in detail below.
With continued reference to the embodiment illustrated in FIGS. 2A-2B, the bracket 35 also includes a pair of rearwardly turned flanges 53, 54 along the upper edge 51 of the body portion 36 (i.e., the pair of flanges 53, 54 extend rearward and downward from the upper edge 51 of the body portion 36 of the bracket 35). The flanges 53, 54 are configured to detachably connect the bracket 35 to one of the crossbeams 13, 14 of the boltless shelving unit 10. In the illustrated embodiment, the flanges 53, 54 are disposed on opposite sides of the tab 50. Each finger 53, 54 includes an upper arcuate end 55 connected to the upper edge 51 of the body portion 36 and a free lower end 56 extending down along at least a portion of the body portion 36 of the bracket 35. The inwardly turned flanges 53, 54 define inverted U-shaped grooves or channels 57 having open lower ends 58 extending up into the channels 57. As illustrated in FIG. 1, the channels 57 are configured to receive a portion of the upper leg 23 of one of the crossbeams 13, 14 to detachably connect the bracket 35 to the desired crossbeam 13, 14 of the shelving unit 10. When the bracket 35 is detachably connected to the desired crossbeam 13, 14, the flanges 53, 54 overhang at least a portion of the upper leg 23 of the crossbeam 13, 14 to retain the bracket 35 on the crossbeam 13, 14. As illustrated in FIGS. 2D and 2E, the flanges 53, 54 may be configured to attach the bracket 35 to crossbeams 13, 14 having a variety of different cross-sectional shapes, such as C-shaped, Z-shaped, or any other suitable shape. In FIG. 2E, the bracket 35 is illustrated detachably connected to a C-shaped crossbeam 13, 14 having upper and lower horizontal flanges 72, 73, respectively, and a vertical flange 74 extending between front ends of the upper and lower horizontal flanges 72, 73. The flanges 53, 54 are configured to extend over and behind the upper horizontal flange 72 of the crossbeam 13, 14, thereby attaching the bracket 35 to the crossbeam 13, 14. In particular, the flanges 53, 54 illustrated in FIGS. 2D and 2E are spaced farther apart from the body portion 36 of the bracket 35, thereby defining a relatively larger channel 57 configured to receive the upper horizontal flange 72 and a portion of the vertical flange 74 of the crossbeam 13, 14. Additionally, the rear surface 38 of the body portion 36 of the bracket 35 is configured to abut the vertical flange 74 on the crossbeam 13, 14. The abutment between the body portion 36 of the bracket 35 and the vertical flange 74 of the crossbeam 13, 14 is configured to prevent the bracket 35 from rocking back and forth when detachably connected to the crossbeam 13, 14, which might otherwise cause the bracket 35 to inadvertently detach from the crossbeam 13, 14.
Referring again to FIGS. 2A-2C, the tab 50 on the bracket 35 extends sufficiently above the flanges 53, 54 such that at least a portion of the upper interlocking member 43 on the tab 50 is spaced above the upper arcuate ends 55 of the flanges 53, 54. In one embodiment, the upper interlocking member 43 is positioned on the tab 50 such that the head portion 48 of the upper interlocking member 43 is spaced above the upper arcuate ends 55 of the flanges 53, 54. In an alternate embodiment, the upper interlocking member 43 may be positioned on the tab 50 such that a portion of the head portion 48 of the upper interconnecting member 43 extends below the upper arcuate ends 55 of the flanges 53, 54. Positioning a portion of the head portion 48 of the upper interlocking member 43 below the upper arcuate ends 55 of the flanges 53, 54 configures the upper interlocking member 43 to overhang a portion of the upper leg 23 of the crossbeam 13, 14 when the bracket 35 is detachably connected to the crossbeam 13, 14. In this embodiment, the upper interlocking member 43 cooperates with the two flanges 53, 54 to attach the bracket 35 to the crossbeam 13, 14 (i.e., together, the upper interlocking member 43 and the two flanges 53, 54 provide three points of attachment between the bracket 35 and the crossbeam 13, 14). In either embodiment, the upper interlocking member 43 is positioned on the tab 50 such that the shaft portion 45 of the upper interlocking member 43 is spaced above or in line with the upper arcuate ends 55 of the flanges 53, 54. Otherwise, the shaft portion 45 of the upper interlocking member 43 may contact the upper leg 23 of the crossbeam 13, 14 before the upper leg 23 is completely received in the channels 57 of the flanges 53, 54, thereby preventing proper engagement between the flanges 53, 54 and the crossbeam 13, 14 (i.e., the tab 50 is configured to position the upper interlocking member 43 such that the shaft portion 45 of the upper interlocking member 43 does not contact the upper leg 23 of the crossbeam 13, 14 before the upper leg 23 of the crossbeam 13, 14 is fully received in the channels 57 of the flanges 53, 54).
Based upon the foregoing description, it will be appreciated that the bracket 35 is configured to be positionable along both the vertical support posts 15, 16 and the horizontal crossbeams 13, 14 of the boltless shelving unit 10. Specifically, the upper and lower interlocking members 43, 44 are configured to detachably connect the bracket 35 to the keyhole-shaped openings 20 in the vertical support posts 15, 16 of the shelving unit 10 and the flanges 53, 54 are configured to detachably and slidably connect the bracket 35 to the crossbeams 13, 14 of the shelving unit 10.
The bracket 35 may be formed from any suitable process, such as stamping, pressing, machining, molding, or rapid prototyping using additive manufacturing. In one embodiment, the interlocking members 43, 44 are welded to the rear surface 38 of the body portion 36. The bracket 35 may be made of any suitably strong and durable material, such as aluminum alloy, steel, plastic (e.g., polyvinyl chloride (PVC) or polypropylene (PP)), or carbon fiber reinforced plastic.
With reference now to the embodiments illustrated in FIGS. 3-5, the bracket 35 is configured to support a variety of different hooks of the present invention. In the embodiment illustrated in FIG. 3, the bracket 35 is configured to support an S-shaped hook assembly 60. The S-shaped hook assembly 60 includes an S-shaped hook 61 and a bushing 62. The S-shaped hook 61 includes upper and lower horizontal legs 63, 64, respectively, an intermediate horizontal leg 65 disposed between the upper and lower horizontal legs 63, 64, a vertical leg 66 interconnecting the upper and intermediate legs 63, 65, and an arcuate portion 67 interconnecting the intermediate and lower legs 65, 64. The lower horizontal leg 64 is configured to support various article(s), such as tools. In the illustrated embodiment, both the intermediate and lower horizontal legs 65, 64 and the arcuate portion 67 have a larger outer diameter than the vertical leg 66 and upper horizontal leg 63. In one embodiment, the lower and intermediate horizontal legs 64, 65 and the arcuate portion 67 of the S-shaped hook 61 may be made out of a material dissimilar to the material of the vertical and upper horizontal legs 66, 63. For instance, the lower and intermediate legs 64, 65 and the arcuate portion 67 may be made out of plastic and the vertical and upper horizontal legs 66, 63 may be made out of a weldable metal, such as steel. Alternatively, the horizontal legs 63, 64, 65, the vertical leg 66, and the arcuate portion 67 may be made out of similar materials. In one embodiment, the horizontal legs 63, 64, 65, the vertical leg 66, and the arcuate portion 67 of the S-shaped hook 61 are all made of metal, but the lower and intermediate horizontal legs 64, 65 and the arcuate portion 67 are coated with an elastomeric material, such as rubber.
With continued reference to FIG. 3, the bushing 62 is a cylindrical tube having an outer diameter and an inner diameter. The inner diameter of the cylindrical bushing 62 is defined by a smooth bore 68 extending the entire length of the bushing 62. At least a portion of the upper horizontal leg 63 of the S-shaped hook 61 is rotatably received in the smooth bore 68 of the bushing 62 such that the S-shaped hook 61 is configured to rotate (arrow 69) approximately 180° (i.e., the S-shaped hook 61 is configured to rotate approximately 180° between a down position, shown in solid lines in FIG. 3, and an up position, shown in dashed lines in FIG. 3).
The bushing 62 may be coupled to the front surface 37 of the bracket 35 by any suitable means, such as bonding, welding, or mechanical fastening. The S-shaped hook 61 may be coupled to the bushing 62 by any suitable means. In one embodiment, an end portion 70 of the upper horizontal leg 63 of the S-shaped hook 61 extends completely through the bore 68 in the bushing 62.
