Application September 11, 1945, Serial No. 615,557
. 1 This invention relates to a foldable supporting structure or stand including two pairs of crosslegs and a shelf pivotally attached to the crossle sg'and has for its object the provision of an improved device of this character. The invention is especially concerned with infants .bathing devices having the foldable cross-legs at the ends of thesupporting structure and arranged to fold into substantial parallelism, and has for its prin cipal object the provision of a shelf foldably interconnected to the supporting structure at the point of pivotal connection of the cross-legs and, to this end, provides a special engaging means for pivotally connecting the ends of the shelf to pins which pivotally connect the cross-legs together.
In one of its advantageous embodiments, the invention provides a slotted bracket on each end of the shelf for attaching the shelf to pins having means for cooperating with a self-locking spring clip to hold the shelf in secured pivotal connection with the cross-legs. In a preferred and advantageous embodiment, the invention provides a slotted bracket having an annular depression concentric with a hole for receiving a headed pin and a self-locking spring clip which fits into the annular depression and has spring means for effecting a lockin engagement with the head of the pin.
These and other novel features of the invention will be better understood after considering the following discussion taken in conjunction with the accompanying drawings, in which:
Fig. 1 is a perspective view of a bathing device embodying the invention;
Figs. 2 and 3 are fragmentary views, partly in section, taken along vertical planes intersecting the connecting points of the cross-legs I, 2, showing two different positions of the parts;
Fig. 4 is a fragmentary enlarged side view of a part of the apparatus of Fig. 1 taken at the intersection of the cross-legs showing the shelf connected;
Fig. 5 is a plan view of Fig. 4, and
Fig. 6 is a view similar to Fig. 4 showing the shelf prior to connection.
The improved infant's bathing device illustrated in the drawings comprises a supporting structure including a pair of foldable cross-legs I and 2 at one end of the bathing device and a pair of similar cross-legs 3 and 4 at the other end of the bathing device. The cross-legs I and 4 are connected at the top by longitudinal rail 5 and at the bottom by longitudinal rail 6. Crosslegs 2 and 3 are connected at the top by longitudinal rail I and at the bottom by longitudinal rail 2 Claims. (Cl. 248-166) 2 8. The cross-legs I and 2 and cross-legs 3 and i are pivotally connected together by the pins I0, and the upper rails 5 and I support the collapsible fabric tub 12. The bathing device is preferably provided withthe usual dressing table and screen guard (not shown) and may include any of the other accessories usually provided.
The means for pivotally attaching the shelf II to the cross-legs are the same on both ends and I shall, accordingly, identify those elements with the same characters. As shown in Figs. 2 and 3, the legs I and 2 are connected together with a pin I0 having a large flat head I2 on the outside and a small head I3 formed by the annular cut I4. Normally, the legs I and 2 are held in the spaced positions shown in Fig. 2 by reason of the relative differences in length between the short rails I and 8 with respect to the longer rails 5 and t. The cross-legs may be squeezed together to the closed position shown in Fig. 3. The shelf I I has a sheet metal bracket I6 permanently attached to each end, as by screws or rivets II. The projecting end has an annular depression I8 (Fig. 3) embracing the end of the slot I9 which provides an opening concentric with the depression in which the pin I0 operates in pivotal connection with the bracket (Figs. 2 and 4) when the slot is slid over the pin, as shown in Figs. 3 and 6. The spring clip 2| is punched out of spring steel and has a number of radial slits leaving petals surrounding a central hole 23 which is smaller in diameter than the head I3 and about the diameter of the cut I4.
In assembling the shelf, the legs are squeezed together from the position shown in Fig. 2 to the position shown in Fig. 3. This causes the headend I3 of the .pin to extend from leg 2. The spring clip 2| may have been placed in the position of Fig. 3 or not, as desired, prior to slipping the slot I9 over the pin It. After the bracket is in the position of Figs. 2 and 4 and the spring clip in the position of Fig. 3, the legs are released and permitted to spring outwardly to the spread position of Fig. 2. Since the spring clip is permanently connected to the pin and the exterior diameter of the spring clip is slightly smaller than the interior diameter of the depression I8, the pressure exerted by the legs maintains the spring clip in the depression and thereby secures the shelf to the pin. In a Very simple operation, the shelf may be removed by squeezing the legs together to free the spring clip from the depression and raising the shelf upwardly.
The shelf is held in its operative horizontal position by the end braces 24 which are pivoted to the shelf on screws 25. The braces have end slots 26 which are, as shown in Figs. 4 and 6, slipped over pins 21. By raising the front edge {of the shelf, the notches are removed from engagement with the screws and the shelf may be pivoted on pins [0 to a position in parallelism with legs I and 3. In this manner, the shelf may be folded along with the folding of the cross-legs.
I claim:
1. In a foldable supporting stand including two pairs of foldable cross-legs, the improvement 'which comprises a shelf for the stand, a pin pivotally connecting each pair of cross-legs together, a spring clip, means on one end of each pin for engaging the spring clip, a bracket at each end of the shelf arranged to be supported on one of the pins, means on the bracket for engaging the spring clip to secure the bracket to the pin, said pairs of cross-legs being set with a space therebetween whereby the legs may be pressed together to detach the means on the bracket from the spring clip in the removal of the shelf, and means for bracing the shelf in its horizontal operative position, said shelf being pivotal on the pins whereby it may be swung to assume an inoperative position in parallelism with the legs.
2. In a foldable supporting stand including two pairs of foldable cross-legs, the improvement which comprises a shelf for the stand, a pin pivotally connecting each pair of cross-legs together with a head on one end and a coupling means [on the other end, one set of two rails connecting two of the legs top and bottom, a second set of two rails connecting the other two legs top and bottom, the first-mentioned two rails being shorter than the second set of rails whereby the legs of each pair of cross-legs are spaced apart but may be pressed together to slide over the pin, a bracket at each end of the shelf with means for engaging a pin and the coupling means, whereby the normal spaced position of the legs holds the bracket in engagement with the coupling means, but when the legs are pressed together the brackets may be disconnected from the coupling means to remove the shelf.
