Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to foldable support mechanisms and more particularly to a system for pivotally joining legs to a table or panel above a support surface.

2. Antecedents of the Invention

Jalapeno peppers require a drying and cooking process, in which they are cooked in an upright position over a heat source, such as heated coals, a gas barbecue burner, etc. or left in the sun to dry and cure. Racks have been provided that include apertures into which the elongate peppers are inserted and maintained in substantially upright positions during the drying or cooking process, with the racks being elevated sufficiently above a heat grid, countertop, table or other surface, such that the peppers are maintained in a generally upright position. While legs have been utilized to elevate racks above the heat grid, countertop, table, etc., it has been found desirable to collapse or fold racks to a compact state when not in use, e.g. for home storage, to enable the rack to fit in a dishwasher, for reducing transportation and warehousing costs and to conserve retail shelf space.

Thus, there is a need for providing a jalapeno pepper curing rack having legs which are easily foldable.

SUMMARY OF THE INVENTION

In compendium, a jalapeno pepper rack includes vertical supports for positioning a generally planar panel above a surface. Each support includes a pair of legs pivotally joined to planar flanges extending from the underside of the panel, with a pivot pin seated in a vertical slot of the flange, so that the support is rotatable relative to the panel and the flange about the pin and is capable of vertical translational movement, within a path defined by the height of the flange slot.

The flange includes a first bent tab beneath and in registration with the flange slot and a second bent tab, which extends from a side surface of the flange at an elevation above that of the first tab. Both tabs extend perpendicularly from the plane of the flange toward the support.

An arcuate channel cut into each leg extends from a mouth in a side of the leg to a depending cutout tail, which extends downwardly along a longitudinal axis of the leg. Each support is locked in a support position, with the first tab seated within the tail, to preclude rotation of the support about the pin. Additionally, because the second tab is not registered with the mouth of the arcuate channel and instead abuts a side edge of the leg, an auxiliary restraint against rotation of the leg is provided.

To release the locking engagement and fold, i.e. rotate, the support, the support is pulled downwardly and away from the panel, until the pivot pin is seated at the bottom of the flange slot, whereby the first tab is no longer seated in the tail, but is positioned within the arcuate channel and the second tab is now registered with the arcuate channel. The support legs may then rotate about the pivot toward a folded position. At approximately a midpoint of rotation, a cam formed in the channel contour, engages the first bent tab. Continued rotation results in the cam riding over the tab and causes the leg to move upwardly and the pivot pin to move from the bottom of the slot toward the middle, such that the support cannot be rotated back into the unfolded position without lowering the pivot pin, hence the support, because the channel mouth is no longer registered with the first bent tab.

From the foregoing compendium, it will be appreciated that it is an aspect of the present invention to provide a foldable support system for a table or panel which is not subject to the disadvantages of the antecedents of the invention aforementioned.

A feature of the present invention is to provide a foldable support system for a table or panel of the general character described which is relatively low in cost.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now in detail to the drawings, the reference numeral 10 denotes generally a jalapeno pepper rack which includes a foldable support system 12 constructed in accordance with and embodying the invention.

The rack 10 comprises a generally planar table or panel 14 having a plurality of apertures 16 dimensioned to accommodate jalapeno peppers. It is to be understood, however, that the foldable support system of the present invention should not be construed as being limited to jalapeno pepper racks and may be employed to support any table, panel, work surface, etc., above a base surface, such as a floor, deck, table, counter or bench top or the ground itself.

Pursuant to the invention, the rack 10 is maintained in a generally horizontal position spaced above a base surface, such as a heat grid or barbecue grill, by a pair of supports 18, 20. The supports 18, 20 are of substantially identical configuration, the sole difference being that, as viewed in FIG. 1, they are oriented in opposite directions. Accordingly, the support 20 will hereinafter be described, it being understood that the support 18 is substantially identical thereto. The supports 18, 20 are preferably fabricated sturdy of steel sheet metal, preferably in the order of 16 gauge, by way of a stamping or die cutting process.

The support 20 includes a pair of generally planar legs 22, 24 which extend in parallel vertical planes, with the bottoms of each leg 22, 24 being joined by a stringer 26, to provide a relatively broad surface for engaging a heat cooking grid or barbecue grill formed of spaced parallel rods. It should be appreciated that the entire support 20 is economically formed from a single piece of steel sheet metal having a thickness within the range of 15 to 17 gauge.

It should also be appreciated that the leg 24 comprises a mirror image of the leg 22. A pair of steel sheet metal, e.g. 16 gauge, brackets 28 extend downwardly from the underside of the table 14 at opposite ends thereof. The legs and brackets are of substantially equal width, e.g. 7/8 inch. Each bracket 28 comprises a generally planar flange 30 having a central vertical slot 32 and a first bent tab 34 at its lowermost edge. The first bent tab 34 projects toward the opposite registered bracket. The flange 30 additionally includes a second bent tab 36, which projects in the same direction as the first bent tab 34, extending from a side edge of the flange 30 at an elevation above that of the first tab 34. The legs 22, 24 of the support 20 are nested between the opposed flanges 30.

A pivot pin or rivet 38 is seated in the slot 32 and extends through an aperture formed in the leg 22. A washer 40 may be positioned between the inner face of the flange 30 and the leg 22 as illustrated in FIG. 2 and FIG. 3. Lateral stability for the table is assured with the legs 22, 24 nested between the brackets 28.

An arcuate channel 42 is die cut or stamped into the leg 22 from an open mouth 44, formed in a longitudinal side edge 45 of the leg, toward a depending cut out tail 46, which extends downwardly along a longitudinal axis of the leg. With the foldable support system in an operative position, supporting the table 14, the first tab 34 is seated at the bottom of a receptacle comprising the cut out tail 46 and the second tab 36 is registered with the side edge 45 of the leg 22, adjacent and beneath the mouth 44. The support 20 is thus locked against rotation relative to the bracket 28, by both tabs, 34, 36 as illustrated in FIG. 4.

To fold the support 20, the leg must be unlocked by being moved axially downwardly, away from the table or panel 14, to a position indicated in FIG. 5, wherein the first tab 34 is no longer within the cut out tail 46, but is within the arcuate channel 42 and the second tab 36 is now registered with the channel mouth 44. It should be noted that in such orientation, the pivot 38 is seated at the bottom of the slot 32.

The support 20, comprising both legs 22, 24 and the stringer 26, can then be rotated counterclockwise, as viewed from its FIG. 5 orientation.

From an observation of FIG. 6, it will be noted that when the leg 22 reaches a partially folded position, the upper surface of the first tab contacts a cam 48 formed in the upper surface of the cut out contour of the channel 42. Continued rotation of the leg 22 causes engagement between the cam 48 and the tab 34 to lift the leg 22 upwardly, such that the pivot pin 38 is moved from the bottom of the slot 32 toward the middle, as best seen in FIG. 7.

With reference now to FIG. 7, it should be noted that the distance between the center of the pivot pin 38 and the first tab 34 is greater than the distance between the center of the pivot pin 38 and the side of the leg adjacent the mouth 44. Thus clockwise rotation of the leg will be blocked by contact between the edge of the leg and the first bent tab 34 as illustrated in FIG. 8.

In order to return the support to the unfolded and locked FIG. 4 position, the support is partially rotated counterclockwise from the FIG. 7 position and pulled downwardly, until the pivot pin 38 seats at the bottom of the slot 32, prior to attaining the FIG. 6 angle orientation. The leg can then continue rotation in a clockwise direction until reaching the FIG. 5 orientation. The leg is then urged upwardly or, the table or panel 14 urged downwardly, until the pivot pin 38 seats at the top of the slot 32 and, the first tab 34 seats at the bottom of the cut out tail 46 and the second tab 36 is registered with the side edge 45 of the leg.

Thus it will be seen that there is provided a foldable support system which achieves the various aspects, features and considerations of the present invention and which is well adapted to meet the conditions of practical usage.

As various possible further embodiments might be made of the present invention and as various changes might be made in the illustrative embodiment set forth herein without departing from the spirit of the invention, it is to be understood that all matter herein described or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
