PIVOTED REMOVABLE SHELF AND MOUNTING Tl-IEREFOR Nov. 25, 1958 Filed Jan. 14, 1957 INVENTOR If Jaw l I l l.
ATTORNEYS United States Patent PIVOTED REMOVABLE SHELF AND MOUNTING THEREFOR Joseph P. Zaidan, Philadelphia, Pa.
Application January 14, 1957, Serial No. 633,946
6 Claims. (Cl. 312-325) The present invention relates to pivoted removable shelves and mountings therefor, and more particularly to such devices which are adapted to effectively increase the usable shelf space within a cabinet.
The primary object of the invention is to providea pivoted shelf utilizing a moving pivot whereby a maximum of shelf cross-sectional area may be used.
Another object of the invention is to provide a shelf mounting of the class described above wherein the shelf may be vertically adjusted to a plurality of positions.
A further object of the invention is to provide a pivoted shelf and mounting therefor in which the shelf may be readily removed from its mounting to facilitate the transferring of the contents thereof to another position.
, Another object of the invention is to provide a shelf structure and mounting therefor of the class described above which is inexpensive to manufacture, simple to use, and neat in appearance.
Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:
Figure 1 is a fragmentary perspective view of the invention shown installed in a cabinet.
Figure 2 is a top plan view of the mechanism illustrated in Figure 1, shown partly broken away for convenience of illustration.
Figure 3 is a fragmentary enlarged front elevation of the shelf mounting.
Figure 4 is a fragmentary enlarged horizontal crosssection taken along the line 44 of Figure 1, looking in the direction of the arrows.
Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral indicates generally a cabinet in which the invention is mounted.
The cabinet 10 is of conventional construction having opposite side walls 11 and 12, a rear wall 13, a bottom wall 14, a top wall (not shown), and a door (not shown). The top wall and door of the cabinet 10 have not been illustrated since their relationship to the cabinet 10 is obvious. The cabinet 10 is provided with an arcuate filler strip 15 extending vertically across the corner formed by the side wall 11 and rear wall 13, as best seen in Figures 1 and 2.
The filler strip 15 is secured to the side wall 11 and rear wall 13 by any suitable conventional means. A resilient strip 16 is secured to the side wall 11 forwardly of the filler member 15 and parallel to the forward edge thereof. The forward edge of the side wall 12 is rabbeted at 17 from the top to bottom thereof to form a recess therein.
A round shaft 18 extends vertically from the bottom wall 14 of the cabinet 10 to the top wall thereof so as to be partially received within the rabbet 17, as best shown in Figure 4. The shaft 18 is provided with a plurality of vertically spaced circumferential notches 19, the purpose of which will be later described.
A mounting member 20 comprising an elongated cylindrical portion 21 having a bore 22 extending axially therein is provided with a laterally offset upper end portion 23. A second cylindrical member 24, somewhat shorter than the cylindrical member 21, is provided with a bore 25 extending parallel to the bore 22, and the second cylindrical member 24 is integrally joined to the laterally extending offset portion 23 in spaced relation to the cylindrical member 21. The cylindrical member 21 is provided with a latch bar 26 pivotally secured thereto at 27 and having a latch blade 28 secured to the upper end thereof and arranged to extend through the cylindrical member 21 to engage the notch 19 in the shaft 18.
A spring 29 biases the bar 26 into latching position. The latch blade 28 by engaging the notch 19 in the shaft 18, supports the mounting 20 in adjusted vertical position on the shaft 18 for rotary movement thereabout. When it is desired to vertically adjust the mounting 20, the latch bar 26 is pressed inwardly on the end thereof opposite the latch blade 28 so that the latch blade 28 is retracted from its notch 19 engaging position, thus releasing the mounting 20 for movement to another adjusted position.
A shelf, generally indicated at 30, is provided with a horizontal sheet 31 and an integral upstanding flange 32 formed thereon. The panel 31 is provided with a plurality of ventilating openings 33 extending vertically therethrough to permit the ready passage of air through th panel 31. A rod 34 is arranged in a generally rectangular form and is provided with a vertically extending offset end portion 35 which is adapted to be received in the bore 25 of the mounting 20. The rod 34 is positioned in contact with the underside of the panel 31 and is secured thereto by any suitable means,such a's welding or the like.
The shelf 30 has the corner 36 thereof opposite the offset end portion 35 of the rod 34 arcuately truncated, for reasons to be assigned. The corner 37 of the shelf 30 diagonally opposite to the corner 36 is arcuately truncated as at 38 in a concave curvature, for reasons to be assigned.
In the use and operation of the invention, the shelf 30 is moved forwardly in the cabinet 10, and the mounting 20 swinging on the pivot 18 draws the corner 37 toward the shaft 18, while the corner 36 pivots outwardly away from the rear wall 13. As the shelf 30 swings clear of the cabinet 10, it pivots not only on the shaft 18 center but also pivots about the offset end portion 35 of the rod 34 in the socket 25 so that the shelf 30 can swing completely out of the cabinet 10 to facilitate removal of the material stored thereon. After the shelf 30 has been swung out of the cabinet 10 it can be lifted vertically by sliding the offset end portion 35 of the rod 34 axially out of the bore 25.
The corner 36 is arcuately truncated, as best shown in Figure 2, to permit the shelf 30 to swing past the wall 11 on which it would otherwise drag. The filler member 15 is formed to conform to the shape of the truncated corner 36 so that when the shelf 30 is in the position illustrated in Figure 2, no gap exists between the shelf 30 and the cabinet 10. The resilient strip 16 serves to bias the shelf 30 into engagement With the wall 12 as the shelf 30 is swung into its contained position within the cabinet 10. The concave arcuate truncation 38 of the corner 37 permits the shelf 30 to swing past the shaft 18 without bind ing thereagainst.
As illustrated in dotted lines in Figure 4, the shelf 30, in being swung to contained position within the cabinet 10, engages the side 12 which assists in carnming the shelf 30 into its fully contained position within the cabinet 10. When the shelf 30 has been moved inwardly of the cabinet 10 to nearly its final position therein,'a door (not shown) closing across the face of the front edges of the side walls 11 and 12 will push the shelf 30 into its fully contained position within the cabinet 10.
Having thus described the preferred embodiment of the invention, it should be understood thatnumerous structural modifications and adaptations. may; be, resorted to without departing from the scope/of the appended claims.
