Description

FIELD OF THE INVENTION

The present invention relates to modular shelving systems. These systems can include modular shelving systems having improved shelf support, stability, and assembly.

BACKGROUND

Various systems of modular shelving have been proposed. Generally, such systems include upright supports, shelf supports or brackets, and shelves that are supported by the brackets. Previous systems may be undesirable due to stability, installation, and/or assembly issues. For example, many systems may be unstable, such as when moved or unintentionally pushed from the front or sides. Many systems may also require the upright supports to be mounted to a wall, requiring permanent alteration to the shelf location and often requiring various tools for assembly. In configurations using cantilever brackets attached to the front of the supports, the shelves may be unsteady such as when the bracket is unintentionally moved. In some cases, additional support is given to the shelf unit by providing bases or other supports at the bottom of the upright supports. This may be undesirable, since it may prevent one unit from being placed adjacent to another, increasing the amount of space required for multiple units.

SUMMARY OF THE INVENTION

The present invention provides a shelf system having stable shelf supports and a reduced profile when installed. The invention also allows various configurations to be achieved without the need of tools.
A modular shelf unit according to an embodiment of the invention includes upright supports. In an embodiment, the supports are angled so that the top of each support may be placed against a wall. Similarly, the bottom of each support may be angled away from the wall, providing additional support and resistance to front-to-back movement.
Support brackets may be configured to attach to the back portion of each upright support. The support bracket may include a connector, sleeve or other surface to mimic the outer surface of the upright support, which may provide a stable and secure connection between the brackets and the upright support. Each support bracket may comprise a support beam extending from behind the upright support to the front, and configured to receive and support a shelf. The top edge of each support bracket may be angled slightly downward or upward from back to front, providing additional stability to the shelf. The support brackets may also comprise a clip, opening, or other structure configured to support or connect to an additional component, such as a garment rod. For example, two brackets connected to adjacent upright supports at the same height may have openings allowing opposite ends of a garment rod to be inserted.
Shelves may be disposed between the upright supports and on the top surface of the support brackets. The shelves may include openings at either end configured to receive the upright supports. Thus, a shelf may partially surround the upright supports at either end, providing stability and reducing the likelihood of shifting if a horizontal force is exerted on the shelf. Various lengths and depths of shelves may be used, allowing for customization of the shelving unit or system. For example, deep shelf may be disposed at a height appropriate for use as a desk surface, and narrower shelves may be disposed at various heights above the desk surface for storage. Other configurations including some or all of these features may be used.
The upright supports may be attached to or comprise a base at the bottom end. The base may provide additional front-to-back and/or side-to-side support. It is preferred that the base be narrow enough that two upright supports may be placed roughly adjacent. In some
A plurality of shelves 120 may be placed on the shelf support brackets and between the upright supports 110. The shelves preferably have an opening 125 at each end, allowing the shelves to partially surround a region of each upright support 110. This may be preferable to provide increased stability to the shelves and reduce unintentional movement of the shelves, such as when positioning items on the shelves. The shelves may be the same dimensions, or various dimensions may be used. In an embodiment, each shelf has the same width and depth, providing uniform storage surfaces. In another embodiment, each shelf has the same width, but one or more shelves have various depths. For example, a shelf disposed at a height appropriate for use as a desk or table may have a greater depth than the other shelves in the unit, allowing the shelf to be used as a desk. Other configurations of shelf dimensions may be used.
Each upright support 110 may have a base 140 disposed at the bottom of the support. It is preferred that the base 140 be sufficiently narrow that one unit 100 may be placed adjacent to another unit 100, with a minimum of space between two shelves placed at equal heights on the two units. Thus, the base 140 may be configured such that it does not extend in the direction of the outer edge of the unit more than a distance equal to the amount by which the shelves extend past the upright support. For example, if the openings 125 at either end of the shelves 120 allow the shelves to extend past the upright support by 5 cm, it is preferable that the base not be wider than about 5 cm when measured from the center of the base to the outer edge of the unit. The base may also comprise a rubber or other polymer material in order to increase the amount of static friction between the shelving system and the floor that it is resting on. By increasing the amount of friction, the likelihood that the system will slip away from a wall is reduced.
In an embodiment, a horizontal member 150 may be disposed between the upright supports 110. The horizontal member 150 generally may be any shape. For example, it may be rod-shaped or arched to provide various appearances or support to the shelf unit. The horizontal member may be configured to rest against a wall and provide additional support when the shelf unit is placed near a wall.
In another embodiment, a garment rod 130 may be connected to two shelf supports placed at equal heights on the upright supports. Specific configurations of the garment rod 130 are discussed below.
In another embodiment, the various component of the shelf unit 100 may be assembled without the use of tools. For example, the portions of the upright support 110 above the upper bend 115 and below the lower bend 116 may be attached to the central portion of the upright support 110 by means of a hand-threaded bolt or other connector. The shelf support brackets and shelves may also be attachable by hand. This configuration may allow for more rapid and less error-prone assembly.
FIG. 2A shows a perspective view of a shelf support bracket 200 according to an embodiment of the invention. The bracket comprises a connector 210 with an inner surface configured to rest approximately flush against the back surface of an upright support. For example, if the upright supports 110 described with respect to FIG. 1 are cylindrical, the inner surface of the connector 210 may be semi-cylindrical. One or more connection hooks 215 may be disposed on the inner surface of the connector, allowing the connector to be secured to one of the upright supports. The connection hooks 215 are preferably configured to prevent the support bracket 200 from being unintentionally disconnected from the upright support. A shelf support beam 220 extends from the connector 210. The shelf support beam 220 extends from the connector 210 toward the front of a shelf unit when the support bracket 200 is attached to an upright support. It is preferred that the support beam be configured perpendicular to the long axis of a shelf when connected to an upright support. In an embodiment, the support beam 220 may be angled slightly downward from back to front when the support bracket 200 is attached to an upright support. The configuration and positioning of the support bracket 200 is further described with reference to FIGS. 3A, 3B, and 4.
The shelf support bracket 200 may include one or more protrusions 225 extending from the shelf-supporting surface of the support beam. The protrusions 225 may be inserted into openings on the bottom of a shelf to be supported by the bracket 200, which may prevent unintentional movement of the shelf on the support brackets. For example, the protrusions may reduce side-to-side movement of a shelf placed on the support brackets.
The shelf support bracket 200 may further include an extension and/or opening 230 to receive an additional storage component, such as a garment rod. The opening 230 may be disposed within an extension of the support beam as shown in FIG. 2A, or it may be disposed within the support beam 220. For example, two shelf support brackets 200 may be attached to adjacent upright supports as described with respect to FIG. 1, where each support bracket includes an opening 230. A garment rod may then be disposed between the two support brackets, with one end disposed within the opening 230 of one of the support brackets, and the other end disposed within an opening 230 on the other support bracket. Additional clips or pins as are known in the art may be attached to each of the garment rod to prevent the garment rod from being unintentionally removed.
The connector portion of the support bracket 200 may be configured to exactly mimic the outer perimeter of the uprights. Thus, if the outer perimeter of the uprights is in the form of a pentagon, the connector 210 may also itself form three wall of the pentagon. Likewise, if the upright is it the shape of a hexagon, the connector 210 may have three sides that mimic the dimensions of the upright.
FIG. 2B shows an extension clip 250 that may be attached to a shelf support bracket. The clip includes a securing portion 251 configured to slide onto a shelf support bracket and an extension connector 252. The securing portion 251 may be made of a semi-flexible material. In such a configuration, the securing portion is preferably flexible enough to allow the securing portion to be easily placed over a shelf support bracket, but rigid enough to grip the support bracket tightly. The extension connector may be configured, for example, to fit within the inner diameter of a hollow or partially-hollow garment rod. One extension clip 250 may be attached to each of two support brackets connected to upright supports, allowing a garment rod or other item to be secured between them. Other extension clip configurations may be used, for example having a hook or loop allowing other items to be connected.
FIGS. 3A-3B show perspective views of a support bracket 200 disposed near an upright support 110. Each upright support 110 may have a plurality of openings 111 disposed in a line on the rear surface of the upright support, allowing the support bracket to be connected at multiple locations on the upright support. When the support bracket 200 is connected to the upright support, the connection hooks 215 are disposed within corresponding openings 111. Preferably, the connection hooks are configured to have a locked position to prevent separation of the support bracket 200 from the upright support 110. For example, the support bracket 200 shown in FIGS. 3A-3B has connection hooks that are roughly L-shaped. When the support bracket 200 is positioned against an upright support 110 such that the connection hooks 215 are disposed within openings 111, the support bracket may be moved downward. Each connection hooks 215 may then extend below the bottom of the opening 111 within which it is disposed, preventing the support bracket 200 from being removed from the upright support without repositioning the support bracket.
FIGS. 3C-3D show top and side views, respectively, of a support bracket 200. The connection hooks 215 may be disposed within the connector 210. A shelf support beam 220 extends from the connector 210. The shelf support beam may be configured such the connector 210 does not intersect a plane defined by the shelf support surface. Protrusions 225 extending from the shelf support beam may be used to secure a shelf to the shelf support surface.
FIG. 4 shows a shelf unit according to another embodiment of the invention. An arched horizontal member 150 is connected to the upright supports 110. A garment rod 130 is connected to and supported by opposing shelf support brackets 200. Various shelves 120 are disposed between the upright supports 110 and supported by opposing shelf support brackets (not shown). Thus, various shelves and bars can be alternated or switched randomly in the shelving system of the present invention.
FIG. 5 shows a shelf unit according to an embodiment of the invention placed near a wall 500. The top of each upright support 110 contacts the wall 500. In an embodiment, the back edge of one or more of the shelves 120 may also contact the wall to provide additional support to each shelf and/or the unit. Hence, the upper bend 115 of the upright connectors may be configured to match the amount of each shelf 120 that extends beyond the back of the upright supports 110. The bottom portion of each upright support 110 may be disposed toward the front of the unit due to lower bend 116 as previously described.
FIG. 6 shows a modular shelf unit according to another embodiment of the present invention. Each shelf unit 610, 620 is a modular shelf unit similar to the unit 100 described with respect to FIG. 1. The units 610, 620 may have shelves of various sizes as previously described. Each unit 610, 620 may be in a similar configuration, i.e., shelves of the same size and location, or each unit may be configured individually. A connecting shelf 630 may be disposed between the units 610, 620 and supported by shelf support brackets connected to one upright support of each unit. Shelves of various lengths and depths may be disposed between the units 610, 620, and multiple shelves may be used. Similarly, multiple units may be connected via additional shelves.
FIG. 7 is an embodiment of the present invention where four uprights are used. As can be seen in FIG. 7, there are two inner uprights and two outer uprights with the inner uprights being spaced less than a shelve width apart and the outer uprights being spaced two shelve widths apart. This figure shows that numerous configurations of the present invention are plausible.
FIG. 8 shows a top view of an end of a shelf in a shelving system of the present invention. Visible in the figure are a support 810, a support shelf bracket 830, and a shelf 820. As can be seen the shelf 820 has an opening 825 that allows the end of the shelf to extend beyond the support 810 and the bracket 830. As can also be seen, the support has a hexagonal cross-section and the end 835 of the support bracket 830 having the connection hooks 815 is configured to mimic the outside perimeter of the hexagonal support 810. Also evident in this figure is that the support 810 is cantilevered on a single side of the support 810.
FIG. 9 shows a side view of the support system shown in FIG. 8. As can be seen in this figure the shelf 820 rests on top of the bracket 830 and the end 835 of the bracket does not extend up over a plane defined by the top of the shelf 820. As can also be seen, the top of the bracket 830 is shown perpendicular to the support 810.
