Application led Deeember 11, 191'3. ISerial No. 805,908.y
To all whom t may concern Be it known that I, CHARLEs' A. Knssnen, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and y State of Pennsylvania, have invented 'new and useful Improvements in Folding Shelves, of which the following a. specifil cation.
My invention relates. to folding shelves,
designed especially for 'display stands forfruit or other objects. A
The object lof my invention -is tol provide display, stands or analogous structures with folding or collapsible shelves.
y proved hingesforsuch shelves'or other fold` y 3 looking toward t A further object is to provide for such stands or structures suitable folding supports. i
A still further-object is torprovide iming objects.
Referring to the accompanying drawings, Figure 1 is-a vertical cross-section of a folding stand embodying my invention; Fig. 2, a front view thereof; Fig. 3, fan enlarged side view of one` of the hinges shown on Figs. 1 and 2; Fig. 4, an elevation of Fig.
of a second form of hinge;` Fig. 6, a side lview of a third form of hinge; Fig. 7, a front view of Fig. 6; Fig. 8, a side vie'w of a fourth form of hinge, showing the parts in one'position; Fig. 9, a view of the hinge shown in Fig. 8 with the parts in a different position; and Fig. 10, a side view'of a fifth form of hinge. y
On Figs. 1 and' 2, I' show a vertical rectangular frame having the vertical end members 1 and 2, connected together by the Y horizontal members 3 and 4. To .the front faces of the members 1 and 2 and near the lower ends thereof, I secure the U-shaped brackets 5, between the free ends of which I pivot the horizontal supports or braces 6, so
. that the latter can beswung out at right angles to the frame with their outer ends on the iioor, ground, or other surface on which the frame stands. The braces 6 may be swung so as to lie parallel with the member e left ;"Fig. 5,11 side view i web or ange 12 arranged at right angles tothe base l1 and secured thereto by heading down the lugs 13 projectingfrom the flange 4through holes in the base. The forward edge of the fiange 12 is bent laterally at a rlght angle to the flange so as to form the front guide orI lug 14. The rear edge ofthe flange 12 next to the base 1() is also bent opposite the lug 14 so as to form a rear gulde or lug 115.1 'The lugs 14 and 15 lie on the same side of the web or flange 12. vThe hinge or member 8 comprises an angle piece of iron or steel having the vertical member 16 secured to the bottom thereof. The shelf 7 is secured to the angle piece by the screws 17. The member 16 is a flat piece of iron or Steel arranged parallel and in contact with the ilangesor web 12 andfhaving the vertical slot 18 for the headed pin` 19 which is secured in the web 12, the head of the pin lying over the outer face of the member 16. The lower end of the member 16 lies between the lugs 14 and 15, which guide the same and hold the shelf steady, the lug 15 preventing the member 16 Afrom any tendency to pry the web 12 away from the base 10. By raising the `member 8 and thereby causing the member 16 to travel up on the pin 19 until the lower end nf the slot engages the said pin, the member 8 may be swung downwardly on the pin 19 as a center, the forward edge of the'member finally resting on the top of the lug 14 (dotted lines, Fig. 3), which preferably has its upper end below the pin 19 by a dlstance equal to the distance between the slot 18 and the front edge of the member 16.
On Fig. 5, I show the base flange 12a in one piece. I omit the lug 15 and have the member 16 engage the base directly. In the place of the lug 14, I provide the headed pm 14l secured in the flange' 12a and having -its head overla ping the member 16. The operation will e readily understood as it is the same as in Fig. 3. The member 8 is shown folded in dotted lines.
On Figs. 6 andv 7, the parts are the same as on Fig. 5 except that the headed pin has been replaced by the lug 14", which is practically the same as the lug 14 in Fig. 3.
On Figs. 8 and 9, the base 10 and flange or web 12c'are substantially. as in Fig. 3, but the lug 14 and the pin 19 are replaced by the two pins 20 and 21 arranged one vertically over the other and secured in the v1()a and thel llO flange or web 12l whichhas the two pins 22 and 23 in the slots 24 and 25 in the memberA 16. The slots 24 and 251are drawn from radii having their center between the said pins so thatJ the slot 211 occupies substantially. the upper left quadrant and the slot substantially the lower right quadrant of a circle drawn from the said center. The lower endl of the slot 24 and the upper end of the slot25 have the horizontal' extensions 2G and 27, respectively, both extending forwardly or away' from thebase 10d. Normally the pins 22 and 23 rest in the /extensions 26 and 27. By pulling the member 8 forwardly or to the left,-the` arc-shaped slots 24 and 25 arewbrought into registry with the pins 22, and 23, whereupon the member, 8 may be rotated to the dotted position.
I claim- In a folding stand, a frame, a shelf therefor, and a hinge connecting the frame and the shelf, one member of the hinge being Secured tothe frame and comprisinga base,
a vertical flange thereon extending at a' right angle to the base and provided with two projections at right angles thereto, the second member of the hinge comprising a horizontal portion secured to vthe shelfand a vertical portion secured to the horizontal portion and provided with at leastone slot CHARLES A.
