The present disclosure relates to shelf assemblies, and more particularly, to shelves and support posts for shelf assemblies.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Modular shelving systems include a plurality of shelves vertically stacked and interconnected via vertical support posts. Typically, each shelf includes an opening at each corner configured to receive an end of a support post thereby allowing successive shelves to be stacked by inserting support posts in the openings of adjacent shelves. The number of shelves and height may be influenced by what the shelves are being used for and the amount of space available where the shelf system is placed.
Undesirably, when a shelf is heavily loaded, the shelf may deflect or sag wherein the shelf is no longer a substantially flat surface and thereby reducing the structural integrity of not only the shelf, but the entire shelving system. This can lead to the items placed on the shelf system to shift, tip over, and/or fall causing damage to the items and anything else surrounding the shelving system. Heavy loads can also cause the support posts to bow in such a way that further reduces the structural integrity resulting in the shelving system itself tipping over and possibly causing damage to the items on the shelf, the shelfing system and anything else in the vicinity of the shelving system.

In a particular embodiment, a modular shelf system having a plurality of shelf assemblies vertically stacked in alignment with one another is shown. The shelf assemblies are stacked one over the other. A plurality of support posts extend between each shelf assembly. In one example, the shelf system includes five shelf assemblies and five support post extending between each shelf assembly configured to interconnect and stabilize the shelf assemblies.
In a non-limiting example, the shelf system may be formed from a lightweight plastic material such as a polypropylene plastic material, by a molding process such as injection molding. However, it should be understood that the shelf system may be formed from any suitable material, including other thermoplastic materials such as polyethylene, and non-thermoplastic materials such as foam or metal. Nonetheless, one skilled in the art may employ any suitable process for forming the shelf system, as desired.
Each shelf assembly includes a shelf body having a first end and a second end, and a shelf end cap connected to each one of the first end and the second end. The shelf end cap is configured to provide additional stability to the shelf system. In a non-limiting example, the shelf assemblies may be substantially rectangular, however, it should be understood that one skilled in the art may employ other shapes, as desired.
Each shelf body further includes a top side, a bottom side, and a plurality of receiving holes extending between the top side and bottom side of the shelf body. Each shelf body includes five receiving holes, wherein four of the five receiving holes are located at corresponding corners of the shelf body and the fifth receiving hole is centrally located at a rear portion of the shelf body. More specifically, the shelf body includes a first receiving hole at a front right corner, a second receiving hole at a front left corner, a third receiving hole at a rear right corner, a fourth receiving hole at a rear left corner, and a fifth receiving hole between the third and fourth receiving holes. The third receiving hole, fourth receiving hole, and fifth receiving hole may be equally spaced along the rear portion of the shelf body.
Each receiving hole includes an upper opening on the top side of the shelf body and a lower opening on the bottom side of the shelf body. The upper and lower openings are configured to facilitate stacking of the shelf assemblies. It should be appreciated that one skilled in the art may employ any number the receiving holes or the location of the receiving holes depending on the overall shape of the shelf body.
Each support post includes a top portion and a bottom portion. The top portion of the support post is configured for sliding engagement with the lower opening of the receiving hole. The bottom portion of the support post is configured for sliding engagement with the upper opening of the receiving hole. As such, the upper opening and lower opening of each receiving hole is geometrically shaped to correspond with a shape of the top portion and bottom portion of the support posts, respectively. For example, the lower opening of the receiving hole is square shaped to correspond with a support post defining a square shape.
The top portion of the support post may define a width less than a width of the lower opening of the shelf body to facilitate fitting of the top portion into the lower opening. The bottom portion of the support post may define a width less than a width of the upper opening of the shelf body to facilitate fitting of the bottom portion into the upper opening.
The shelf system may further include a top cap configured to be disposed through the upper opening of each receiving hole on the upper most shelf assembly. The top cap includes a cap body defining a width that is smaller than a width of the upper opening of the shelf body to facilitate fitting of the cap body into the upper opening.
The shelf end cap includes at least two arms configured to be inserted into arm openings on the first and second ends of each shelf body. Each arm is shaped such that an interference fit is established between each arm and the corresponding arm opening. Each arm of the shelf end cap further defines an aperture having a geographic shape corresponding to the shape of the support post and receiving holes. Each aperture is square shaped to correspond to the square shaped support posts and receiving holes.
In operation, the two arms of the shelf end cap are inserted into arm openings in the ends of the shelf body. Once the shelf end cap is installed, the aperture of the shelf end cap is aligned with the receiving hole of the shelf body. Next, the top cap is inserted into the upper opening on the top side of the shelf body. When the top cap is pushed into place, the cap body is in mating contact with inner walls of the aperture of the shelf end cap and an inner wall of the receiving hole establishing an interference fit.
In certain embodiments, each shelf end cap may have a plurality of interlocking apertures formed on an outer wall, a first side wall, and a second side wall of each shelf end cap. In a non-limiting example, there may be two interlocking apertures formed in the outer wall, and a single interlocking aperture formed in each side wall. The interlocking apertures may be configured to receive an interlocking component. The interlocking component may have a symmetrical shape, which permits the interlocking component to be received by different interlocking apertures of the same shape.
In one embodiment, the interlocking component is generally H-shaped. In this embodiment, for example, the interlocking apertures are generally T-shaped to receive a portion of the H-shaped interlocking component. In particular, a T-shaped portion of the at least one interlocking component is configured to be received by the T-shaped interlocking aperture. However, one of ordinary skill in the art may select other suitable shapes for the interlocking aperture and the interlocking component, as desired. Advantageously, the interlocking apertures and the interlocking component are used to connect multiple shelf assemblies. For example, a first connecting portion of the interlocking component is disposed in each shelf end cap of a first shelf assembly, and a second connecting portion of the interlocking component is disposed on the shelf end cap of a second shelf assembly.
The upper most (top) shelf assembly has a top cap installed in the upper opening of each one of the five receiving holes.
The shelf system may include an adjustable foot and an adjustor adapted to reinforce the shelf system. The adjustable foot may be disposed within the lower opening of the receiving holes of the bottom most shelf assembly of the shelf system. The adjustable foot is configured to alter the height of the shelf system. The adjustable foot may have an externally threaded portion and the adjustor may have an internally threaded portion, whereby the height of the adjustable foot is adjusted by rotating the adjustable foot clockwise or counterclockwise. For example, the adjustor may lower the height of the adjustable foot by rotating clockwise and raise the height of the adjustable foot by rotating counterclockwise.
The shelf system may include a wall anchor configured to secure the shelf system to an adjacent wall thereby inhibiting the shelf system from tipping over. The wall anchor includes a front wall and opposing side walls configured to engage a support post adjacent the wall. Each opposing side wall includes an outwardly extending protrusion defining a through hole for receiving an attachment feature, such as a nail or screw, for attaching the wall anchor to the wall. When the wall anchor is installed, the front wall, opposing side walls, and the wall enclose the support post thereby securing the shelf system to the wall. One skilled in the art may employ two or any number of wall anchors, as desired.
The shelf system may include a plurality of shelf assemblies, where the shelf assemblies are vertically stacked one over the other in alignment with one another. A plurality of support posts extend between each shelf assembly and are configured to interconnect and stabilize the shelf assemblies. Each shelf assembly includes a shelf body, a shelf end cap attached to ends of the shelf body, a plurality of receiving holes, and a plurality of top caps disposed in a corresponding receiving hole. The plurality of receiving holes are disposed at each corner of the shelf body. In a non-limiting example, a fifth receiving hole is centrally located at the rear portion of the shelf body. The difference between this shelf system and other embodiments is that each receiving hole defines an octagonal shape, as opposed to a square shape.
The octagonal receiving holes are configured to receive an octagonal support post to facilitate stacking of the shelf assemblies. The support post and receiving hole connection further provides stability and support to the shelf system. It has been advantageously found that providing a fifth support post, centrally located between opposing corners, inhibits the center of the shelf body from sinking when the shelf is heavily loaded thereby increasing the structural integrity of the shelf system.
It should be understood that the plurality of top caps define a shape that corresponds to the shape of the receiving hole.
A modular shelf system according to another embodiment of the present disclosure includes that each receiving hole of this shelf system defines a circular shape instead of square or octagon shapes. Each circular receiving hole is configured to receive a circular support post. Furthermore, the shelf system may include a plurality of top caps defining a shape corresponding to the shape of the receiving hole.
It has been advantageously found that providing a fifth support post, centrally located between opposing corners, inhibits the center of the shelf body from sinking when the shelf is heavily loaded thereby increasing the structural integrity of the shelf system.
