Definitions
- the specification discloses a drainboard whose face panel includes inverted triangular shaped apertures for receiving removable pegs.
- the pegs have a shoulder, an arm extending outwardly from the front of the shoulder, a neck extending rearwardly from the shoulder and having an inverted triangular shaped cross section, and an enlarged head on the neck which can be inserted through the aperture in the panel until the shoulder engages the panel. The peg is then slid downwardly to thereby lock the peg onto the panel and prevent rotation thereof.
- the drainboard of the present invention includes pegs having a neck extending rearwardly from the peg shoulder and having a head positioned on the neck at a point spaced from the shoulder. The head is larger in lateral cross section than the neck, and the shoulder is larger in lateral cross section than both the neck and the head.
- the aperture in the pegboard panel for receiving the peg is at least as large as the head but is smaller than the peg shoulder.
- the head is inserted through the aperture and the peg is slid downwardly until it engages the lower portion of the aperture.
- the marginal portions of the head which extend away from the neck, engage the rear surface of the panel.
- the peg is thus easily locked in place on the panel by inserting it through the aperture and sliding it downwardly. Similarly, it can readily be removed to facilitate cleaning of the panel by sliding the peg upwardly and then pulling it out of the aperture.
- the lower portion of the aperture is non-circular in configuration and the neck is similarly non-circular in lateral cross-section such that when the neck engages the edge of the lower portion of the aperture, the peg cannot be rotated.
- the arm which extends upwardly from the shoulder will always be locked in its upwardly extending position.
- FIG. 1 is a perspective view of the drainboard
- FIG. 2 is a fragmentary view of a portion of the drainboard panel showing the inverted, triangular shaped aperture therein;
- FIG. 3 is a rear elevational view of a peg employed on the drainboard
- FIG. 4 is a front elevational view of the peg
- FIG. 5 is a side elevational view of the peg
- FIG. 6 is a cross-sectional view taken generally along plane VIVI of FIG. 1 but with the peg left intact.
- the drainboard l of the present invention comprises a sheet-like panel 10 having a plurality of inverted, triangular shaped apertures 20 therein for receiving the removably mounted pegs 30 (FIG. 1).
- Each peg 30 is preferably molded of a plastic material such as polyethylene.
- Peg 30 includes a shoulder 31 (FIGS. 3, 4, and 5) having a front face from which extends an upwardly slanting arm 32.
- a short, stubby neck 33 extends rearwardly from the rear surface of shoulder 31 (FIG. 5)
- Both head 34 and neck 33 are of an inverted triangular configuration in lateral cross-section (see FIG. 3 in which neck 33 is shown by hidden lines).
- the base of the triangle defined by the cross-section of neck 33 is located at the top thereof and the apex of the triangle is located at the bottom thereof. The same is true with respect to head 34. Further, the bases of the two triangles are flush with one another.
- Head 34 is larger in lateral cross-section that neck 33 so that head 34 includes marginal portions 34a which extend beyond the edges of the sides of neck 33 (FIG. 3).
- neck 33 from shoulder 31 to head 34 is approximately equal to the thickness of the sheet-like panel 10 of drainboard l.
- Shoulder 31 itself is larger in lateral cross-section than both neck 33 and head 34.
- Shoulder 31 is also generally triangular in configuration, but it constitutes an upright triangle so that when liquid drains down the face of panel 10, it drains downwardly over and off of the sloping sides 31a and 31b of the triangle defined by the margin of shoulder 31 (FIG. 3 and 4).
- each inverted triangular shaped aperture 20 in panel 10 is approximately the same in shape and dimension, or possibly slightly larger than, head 34.
- each aperture 20 is smaller than the lateral cross-section area of shoulder 31. This allows head 34 to be inserted through an opening 20, but prevents shoulder 31 from being inserted through opening 20.
- each triangle defined by aperture 20 is the same as the angle of the apex of the triangle defined by the cross-section of neck 33.
- the sidesof neck 33 and the apex of the triangle defined by the cross-section of neck 33 come snugly into engagement with the apex and lower edge portions of the sides I provide a means for locking peg 30'against rotation on panel when it is slipped downwardly so that the lower sides of neck 33 come into engagement with the lower edge portions of aperture 20.
- Panel 10 itself is comprised of a relatively, thin, sheet like material such as sheet stainless steel. It is important that the sheet like material be relatively thin so that neck 33 does not have to be exceptionally long. If neck 33 were too long, it would comprise a rather delicate extension, subject more readily to bending forces, which could have a greater tendency to fracture than will the shorter neck 33. Panel 10 is bent over at its edges to definea margin 11 and an outwardly protruding bottomdrain lip 12, these features being more fully set forth in my prior U.S. Pat. No. 3,779,392, which is specifically incorporated herein by reference. Similarly, the means for hanging drainboard 1 are more fully disclosed in the aforesaid Pat. No. 3,779,392.
- each peg 30 is readily mounted onto panel 10 by inserting its head 34 through an aperture and then sliding peg 30 in a downward direction until neck 33 comes into engagement with the lower edge portions of aperture 20. In this position, the extending marginal portions 34a of head 34 are in engagement with the rear surface of panel 10 as can be seen by reference to FIG. 6. In this manner, peg 30 is held inplace on panel 10. Similarly, due to the noncircular configuration of neck 33 and aperture 20, peg
- each peg 30 can readily be removed by sliding the peg 30 upwardly and then pulling it directly outwardly. Because the upper portions of neck 33 and head 34 are flush (i.e., the bases of the triangles defined thereby), one can simply slide peg '30 upwardly until neck 33 engages the top edge of aperture 20 and then one can simply pull peg 30 outwardly Without fear of hooking an upper portion of head 34 behind panel 10 adjacent to the upper edge of aperture 20. Panel 10 can then be wiped clean, as can the rear surface of shoulder 31 on peg 30. Peg 30 can then readily be reinstalled in the manner outlined above.
- a drainboard, display or the like comprising: a sheet panel defining the face of said board; atleast one aperture in said panel for mounting a peg, said aperture being an inverted triangle in configuration with the base of the triangle being positioned at the top thereof and the apex of the triangle being positioned at the bottom thereof; at least one removable peg including a shoulder with front and rear surfaces, an arm extending outwardly and sloping upwardly from said front of said shoulder, a neck extending outwardly from said rear of said shoulder, and a head on said neck at a point spaced from said shoulder; said head being larger in lateral cross-section than said neck whereby said head includes marginal portions extending laterally at least downwardly from said neck; said neck having a length from said shoulder to said head which is approximately equal to the thickness of said panel; said neck also defining an inverted triangle in lateral cross-section configuration with' the base of the triangle at the top thereof and the apex of the triangle at the bottom thereof, the triangle defined by the lateral cross-section
- drainboard of claim 1 in which: there are a plurality of said apertures and a plurality of said pegs.
