DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
The following descriptions of various embodiments are merely exemplary in nature and are in no way intended to limit the invention, its application, or uses.
Aspects of the present invention generally relate to a vertical support standard and track system for supporting shelving brackets, such that the standard is able to receive greater loading capacity and can be moved prior to final positioning, if desired, to various positions across a wall through use of a track. In various embodiments, the horizontally mounted track provides added support to increase the loading that can be placed on the standard and also provides the ability for such standard to be moved to various positions along the track's length. Illustratively, one embodiment of the invention generally includes a shelving apparatus containing a vertical support standard and a track. Embodiments of the invention can also include a shelf and shelving bracket mounted to the standard. The standard may be constructed like a typical wall mounted standard having front and back sides. The front side of the standard may contain a plurality of slots so as to be able to receive tabs or other mounting means of a shelving bracket. The standard can contain one or more columns of slots so as to accept one or more shelving brackets or multi-sided shelving brackets. The back side of the standard, preferably near a top portion, defines an opening having upper and lower surfaces. This opening should preferably be constructed in such a way that it can receive a support portion of a track. The standard may also be able to be moved horizontally along a wall mounted track without becoming detached from the track.
Another component in embodiments of the invention is a track which can be mounted to a wall by any typical mounting means. The track comprises a body which is able to accept a standard. In order to keep such a standard mounted to the track, various embodiments include a track having a lip that extends downwardly and overlaps a front surface of the top portion of the standard so as to prevent the standard from disengaging from the track. The track can also include a support portion having upper and lower surfaces that is adapted to be inserted into the opening on the back of the standard. The opening on the standard and the support portion of the track are preferably aligned so that the front lip of the track is able to engage a front portion of the standard.
The top portion of the standard that engages the lip of the track, and the upper surface of the opening that engages the upper surface of the support portion of the track, provide support for downward loading placed on the standard and keep the standard locked into the track. The lower surface of the opening prevents the standard from being pushed up and disjointed from the track by engaging the lower surface of the support portion of the track. When mounted on the track, the standard is preferably able to move horizontally along the support portion so as to be placed in a desired position by the consumer prior to first mounting of the standard to a wall. In this way, a shelf bracket and shelving system can be mounted to the standard in a location preferable to the consumer while providing maximum support and accepting greater amount of loading such as by an attached bracket and shelf.
According to another aspect of the invention, an exemplary shelving apparatus generally includes a track and a standard. The track includes a support portion having an upper support surface and an extension extending generally outwardly from the support portion. The standard includes a back surface having an opening. When the support portion is within the opening, an upper surface of the opening contacts the upper support surface of the support portion, and the extension is engagingly received within a portion of the opening. This engagement of the extension within the portion of the opening can inhibit disengagement of the standard from the track.
According to another aspect, the present invention methods of supporting standards with a track. In one particular implementation, the track includes a support portion having an upper support surface and an extension extending generally outwardly from the upper support surface. The standard includes a back surface having an opening configured to engagingly receive the support portion. The method generally includes positioning the standard relative to the track such that a portion of the opening engages the extension, the opening engages the support portion of the track, and the upper support surface of the support portion contacts an upper surface of the opening.
According to another aspect, an exemplary shelving apparatus includes a standard and a track. The standard includes a back surface having an opening. The track includes means for supporting the standard. The track also includes means for retaining the standard within the track. When the standard is engaged with the track, an upper surface of the opening contacts the means for supporting, and the means for retaining contacts a portion of the opening.
Any of the aspects of the present invention can be used individually or in combination with any one or more of the other aspects of the present invention.
In FIG. 1, there is shown a cross-sectional side view of a shelving apparatus according to one exemplary embodiment of the invention. As shown, the shelving apparatus comprises a standard 10 and a track 100. The embodiment of the standard 10 shown comprises a front surface 50, a back surface 55, and a top portion 60. The front surface 50 defines slots 70 (as shown in FIG. 3), which in other embodiments can be of any size and shape such that a shelving bracket may be mounted thereto. Alternatively, instead of slots, any other means of mounting a bracket, such as protrusions, may be used on front surface 50.
As shown in FIG. 1, the back portion 55 of the standard 10 defines an opening 20 for supporting the standard 10 on the track 100. The opening 20 defines an upper surface 30 and a lower surface 40. The opening 20 is preferably shaped such that the upper and lower surfaces 30 and 40 are generally horizontal in orientation. The opening 20, however, can be of any shape such that it can receive and be supported by an opposing supporting member and is preferably slidable along that member. The opening 20 can be located on any portion of the standard such that it is supported by engaging with a track.
Also shown in FIGS. 1 and 3 is a track 100, which can be mounted on a wall or other surface, preferably horizontally. Track 100 may be constructed of any material suitable for standards or brackets, such as steel or aluminum. Track 100 also has a length such that standard 10 can preferably slide horizontally along the length of the track 100.
As shown in FIG. 1, the cross-section of an embodiment of track 100 is preferably generally shaped like a backward S. The track 100 also defines a front lip 110 that is designed to abut the front surface 50 of the standard 10 such that the standard 10 is held within track 100. Lip 110 preferably extends some distance over the top portion 60 of standard 10 and comes into contact with the front surface 50 such that when jarred or otherwise moved, the standard 10 is not released from the track 100. Any means, however, such as a latch or other mechanism can also be used in place of the lip 110, as long as the standard 10 remains held within track 100.
Track 100 also defines a support portion 120 that, when engaged with the opening 20, supports the standard 10 and prevents (or at least inhibits) the standard 10 from being pushed upward and separated from track 100. In one embodiment of track 100, support portion 120 (as shown in cross section in FIG. 1) is generally U-shaped and is adapted to extend into opening 20 on standard 10.
With continued reference to FIG. 1, support portion 120 includes upper surface 140 and bottom surface 150. Upper surface 140 supports standard 10, such as when a shelf and shelving bracket and the contents of the shelf are connected to the standard 10. Bottom surface 150 prevents (or at least inhibits) standard 10 from being disengaged from track 100 if the standard 10 is pushed or jarred in an upward direction by engaging with lower surface 40 of opening 20.
Support portion 120 may also be designed to allow standard 10 to slide horizontally along the track if desired, as shown in FIG. 3. Once in a desired position, the portion of the standard 10 not engaged with the track 100 may thereafter be secured to a wall to prevent (or at least inhibit) any further movement of the standard 100 from its desired position.
Alternative embodiments of support portion 120 may also be used. In such alternative configurations, the support portion need only provide an upper and bottom surface adapted to engage opening 20, or other means to support the standard 10 while preferably allowing the standard to slide if desired. Additionally, support portion 120 is not required to be at the bottom of track 100, but can be located at any place on the track 100 such that the support portion 120 can engage with an opening on the back surface of a wall standard and preferably provide one or more of the benefits as described herein. Preferably, however, support portion 120 is located in a position that when inserted into opening 20, lip 110 will be engaged with front surface 50 of standard 10. Thus, as shown in FIG. 1, distance y (the distance between the top 60 of the standard and bottom of the lip 110) is preferably greater than distance x (the spaced distance between the lower surface 40 and bottom surface 150 when the upper surface 140 of the track 100 is in contact with the upper surface 30 of the standard's opening 20). Also, track 100 may be of any cross-sectional design, and such alternative cross-sectional design can provide one or more of the benefits described herein.
In an alternative embodiment as shown in FIG. 4, lip 110 may be eliminated altogether by support portion 120 both providing support and keeping the standard 10 connected to the track. For example, support portion 120 can comprise not only upper and bottom surfaces 140 and 150, but can comprise extension 160 that provides the same function as did the lip 110. In one such embodiment (as shown in FIG. 4), extension 160 prevents the standard 10 from disengaging from the track 100 by engaging a notch or hole 72 in opening 20. The notch 72 and extension 160 may be located on the opening 20 and support member 120 respectively (or vice versa) in any position such that they can engage each other and prevent the standard 10 from disengaging from track 100. The standard 10 is also preferably slidable along the track 100 in this embodiment.
A method of mounting the standard 10 to track 100 is also disclosed herein. Track 100 is first secured to a wall or other surface, preferably in a substantially horizontal manner. A top portion of the standard 10 is then inserted under lip 110 and standard 10 rotated such that the opening 20 on the back 55 of the standard 10 engages the support portion 120 of the track 100. The standard 10 may then be slid along track 100 until it is in a desired position and then attached to the wall to prevent further movement along the track 100.
As shown in FIGS. 2 and 3, standard 10 and track 100 may be used in combination with a shelf 200 and/or shelving bracket 250. Such bracket and shelf can be of any type ordinarily used with vertical wall standards. As described above, standard 10 in combination with track 100 not only preferably allows standard 10 to be horizontally moved so that bracket 250 and shelf 200 can be supported in a position desired by the consumer, but also provides additional support and increased loading capacity for the shelf and bracket.
