The wordings “comprising”, “containing” and “including” used in the specification indicate the presence of the claimed features, but do not repel the presence of one or more other features. The wording “and/or” as used in the specification includes any and all combinations of one or more of the relevant items listed. The phases “between X and Y” and “between about X and V” as used in the specification should be construed as including X and Y. The phrase “between about X and Y” as used in the present specification means “between about X and about Y”, and the phrase “from about X to V” as used in the present specification means “from about X to about Y”.

(12) In the specification, when one element is referred to as being “on” another element, “attached to” another element, “connected to” another element, “coupled to” another element, or “in contact with” another element, the element may be directly located on another element, attached to another element, connected to another element, coupled to another element, or in contact with another element, or there may be present with an intermediate element. By contrast, where one element is referred to as being “directly” on another element, “directly attached to” another element, “directly connected to” another element, “directly coupled to” another element, or “in direct contact with” another element, there will not be present with an intermediate element. In the specification, where one feature is arranged to be “adjacent” to another feature, it may mean that one feature has a portion that overlaps with an adjacent feature or a portion that is located above or below an adjacent feature.

(13) In the specification, the spatial relation wordings such as “up”, “down”, “left”, “right”, “forth”, “back”, “high”, “low” and the like may describe a relation of one feature with another feature in the drawings. It should be understood that, the spatial relation wordings also contain different orientations of the apparatus in use or operation, in addition to containing the orientations shown in the drawings. For example, when the apparatus in the drawings is overturned, the features previously described as “below” other features may be described to be “above” other features at this time. The apparatus may also be otherwisely oriented (rotated 90 degrees or at other orientations). At this time, the relative spatial relations will be explained correspondingly.

(14) The shelf support described herein may be employed in any type of furniture, including but not limited to book cases, cabinets (including china cabinets, curio cabinets, hutches, display cabinets, etc.) and the like. The furniture may be free-standing furniture, as well as installed, custom-made, or wall-mounted furniture such as kitchen cabinets, custom closet assemblies and wall units, etc.

(15) The shelf support described herein may be conveniently formed as a single unitary or monolithic piece or part of a suitable resilient synthetic organic polymer material such as acrylonitrile butadiene styrene (ABS) or polycarbonate. The part may be formed by any suitable process, typically by injection molding. As used herein, “unitary” or “monolithic” means an object that is a single, unitary piece formed or composed of a material without joints or seams.

(16) A shelf support according to embodiments of the invention is designated broadly at 20 and is illustrated in FIGS. 1-5. The shelf support 20 comprises a main body 21 that is substantially rectangular in shape and generally planar and has a front face 25 and a rear face 26. A shelf flange 27 is mounted to and extends from a lower location on the front face 25, and a dowel 28 is mounted to and extends from a lower location on the rear face 26. Two gussets 29 with slightly concave long edges 29a support the shelf flange 27 from underneath. The upper edges of the gussets 29 may extend between about 40 and 70 percent of the length of the flange 27. The dowel 28, which is inserted into a hole in the cabinet wall, may be fluted as shown, may be round, may be a “split dowel”, or may take other shapes known to those of skill in this art.

(17) The main body 21 has a lower opening 30 and an upper opening 31 that are divided by a cross-beam 32. A substantially flat capturing finger 35 is connected to the top edge portion of the upper opening 31. The capturing finger 35 extends forwardly and downwardly in front of the upper opening 31 at an oblique angle α to the main body 21 (typically the angle α is between about 10 and 20 degrees, with an angle α of between 13 and 17 degrees in some embodiments). The lower end 36 of the capturing finger 35 typically extends between about 0.1 and 0.3 inches in front of the front face 25 of the main body 21. The lower end 36 of the capturing finger 35 is spaced from the upper surface of the flange 27; the distance T that separates the lower end 36 and the flange 27 determines thickness (within a range) of a shelf that is mounted therebetween. As shown herein, the capturing finger 35 includes a rib 37 that extends over most of its length. The capturing finger 35 is dimensioned to be collapsibly received within the upper opening 31 when the capturing finger 35 deflects relative to the main body 21.

(18) A centering finger 40 is mounted on and extends forwardly and downwardly away from the cross-beam 32 in front of the lower opening 30. A notch 41 is present in the cross-beam 32 rearwardly of the fixed end of the centering finger 40. The centering finger 40 extends at an oblique angle β relative to the main body 21 (typically the angle β is between about 10 and 20 degrees, with the angle β being between about 14 and 18 degrees in some embodiments). The lower end of the centering finger 40 extends between about 0.005 and 0.188 inches (typically about 0.05 and 0.1 inches) in front of the front face 25 of the main body 21.

(19) FIGS. 6 and 7 show a pair of shelf supports 20 supporting a shelf 10. As shown in FIG. 6, each shelf support 20 is positioned to support the edge portion 11 of the shelf 10 on one wall 12 of a pair of opposing walls in a cabinet or the like, as described above. The wall has at least one, and more typically a series, of holes or openings 13 formed therein to receive and hold the shelf support 20, as described below. In a typical embodiment, four shelf supports 20 would be used to support a shelf, with two such supports supporting opposite ends of each shelf edge portion.

(20) During installation, shelf supports 20 (typically four two on each opposing wall of the cabinet) are mounted to the walk 12 of the cabinet by inserting each dowel 28 into a respective hole 13 in one of the cabinet walls 12. The shelf supports 20 are all mounted at the same elevation. A shelf 10 is then lowered onto the shelf supports 20, As the shelf 10 descends, the side edges 11 of the shelf 10 contact the forward surfaces of the capturing fingers 35, causing the capturing fingers 35 to deflect rearwardly toward (and in some instances into) the upper openings 31. Once the upper surface of the shelf 10 passes the lower end 36 of the capturing fingers 35, the deflected fingers 35 recover toward their original positions. The lower surface of the shelf 10 rests on the flanges 27. The lower end 36 of each capturing finger 35 is positioned above the shelf 10, either in engagement with the shelf 10 or just above it. Thus, the capturing fingers 35 can maintain the shelf 10 in position and prevent the shelf 10 from being dislodged via upward movement.

(21) It should be noted that the presence of the rib 37 on the capturing finger 35 can assist in the installation of the shelf 10. More specifically, the rib 37 increases the stiffness of the capturing finger 35. As a result, when the shelf 10 contacts the capturing 35, not only is there some deflection of the capturing finger 35 relative to the main body 21, there is also deflection of the upper portion of the main body 21 away from the cabinet wall 12, which further causes the lower end 36 of the capturing finger 35 to travel toward the main body 21. These combined actions can make it easier to slide the shelf 10 past the lower end 36 of the capturing finger 35. However, once the shelf 10 clears the lower end 36 of the capturing finger 35 and the capturing finger 35 recovers to its original, relaxed position, the additional stiffness provided by the rib 37 can help to retain the shelf 10 in place.

(22) Moreover, the presence and/or location of the concave edge 29a of the gussets 29 of the shelf support 20 can improve the ergonomics of installation of the shelf support 20 into (and removal from) a respective hole 13 in a cabinet wall 12, The concave shape of the long edges 29a can provide a relatively comfortable surface for the installer's fingers or thumbs to squeeze against, which can improve speed and consistency of installation and/or removal of the shelf support 20.

(23) In addition, once the shelf 10 passes below the lower end of the capturing finger 35, it may contact the centering finger 40 with its side edge 11 and deflect the centering finger 40 toward the lower opening 30. As the centering finger 40 deflects, it exerts a force against the shelf 10 toward the opposite wall 12 of the cabinet. The forces exerted by the centering fingers 40 on opposite sides of the cabinet tend to force the shelf 10 into a centered position between the walls 12 of the cabinet.

(24) While shelf supports of the present invention are intended to be used in pairs, and particularly two pairs for each shelf, it will be appreciated that a shelf support of the invention could be used on one side of a shelf and a different type of support could be used on the other side, particularly where sufficient locking is obtained with a single locking-type shelf support. It will also be appreciated the some, all, or none of the supports may include a side abutment portion, depending upon whether the cabinet has a solid back, front edge portions, or the like

(25) The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. The invention is defined by the following claims, with equivalents of the claims to be included therein.
