Bernstrom, 1810 Brownsboro Road, Louisville, Ky. 40206, and Robert L. Jones and Dennis H. Jones, both of 10301 Taylorsville Road, Jelersontown, Ky. 40029 Filed Apr. 26, 1965, Ser. No. 450,793 Claims. (Cl. 249-126) ABSTRACT 0F THE DISCLOSURE An ice cube molding assembly having a plurality of trays with ice molding pockets, extending supports formed on the upper side of each tray and mating notched support receivers formed on the lower side of each tray for holding the trays in alignment and separated when stacked, and a hailed pan for suppporting a stack of the trays.

Summary of the invention Many types of home refrigerators are provided with freezing compartments which do not have any means for holding stacks of ice molding trays and, consequently, it is necessary to place one or more trays on the floor of the freezing compartment whereby a substantial area of the compartment will be occupied by the trays, and it is not possible to store packages of frozen food or other items in the space above the ice trays. Conventional ice molding trays do not have any structure for permitting stacking of trays so that there is no means of preventing trays from slipping sideways with respect to one another, and there is no means for spacing trays one above the other for permitting air to circulate between trays or for preventing trays from freezing together. Accordingly, the prior art provides no convenient means for freezing relatively large quantities of ice cubes in many types of conventional home refrigerators.

The principal object of this invention is to provide ice molding trays having means so arranged that a plurality of trays may be stacked one upon the other in spaced relation to one another and in such a manner that the stacked trays will not slip olf of one another.

Another object of this invention is to provide an ice cube molding assembly consisting of a carrying means adapted to support a plurality of stacked ice cube molding trays, each tray having means for retaining it in vertical alignment with trays above and below it.

In accordance with this invention there is provided an ice cube molding assembly comprising a pan member having a plurality of ice cube molding trays stacked thereon, each tray including means for supporting and/ or retaining it in vertical alignment with said pan and with upper and lower trays, and a pair of bails spanning the stack and pivotally attached to the ends of said pan and in spaced relation to one another.

Also, in accordance with this invention there is provided an ice tray comprising a plurality of longitudinal and transverse rows of ice molding pockets separated on the lower side thereof by channels and joined together at their top edges, and tray stacking and aligning means consisting of piloting supports disposed on the upper side of the trays and mating support receiving means disposed in said channels.

The fullnature of the invention will be understood from the accompanying drawings and the following description and claims.

FIG. l is a top plan view of a stack of ice molding trays and carrier as provided in accordance with this invention.

ICC

FIG. 2 is an end view of the stack illustrated in FIG. 1.

FIG. 3 is an enlarged fragmentary perspective view of an ice tray and one of the tray aligning and supporting members illustrated in FIG. l.

FIG. 4 is an enlarged fagmentary perspective view of the bottom of an ice tray illustrating web members which cooperate with the aligning and supporting member illustrated in FIG. 3.

FIG. 5 is an enlarged cross section taken on line 5-5 of FIG. l.

FIG. 6 is a perspective view of the ice tray carrier illustrated in FIGS. l and 2.

Referring to the drawings there is provided in accordance with this invention an ice tray 10 which may be formed of conventional metalic or plastic material to provide a plurality of ice molding pocket members 11 joined together at their upper edges as illustrated at 12 and separated `on the lower side thereof by longitudinal channels 14 and transverse channels 15. As illustrated in the drawings, each tray may consist of 49 pocket members, and4 trays may bestacked one upon the other to form an assembly which will mold 196 ice cu-bes. For supporting the trays 10, as an assembly or as a package, there is provided a pan 17 on which the trays may be stacked. The pan may be formed to have vertical lip members 18 to which bails 19 and 20 are pivotally mounted in spaced relation lto one another. The bail 20 may lbe slightly longer than the bail 19 so that both bails may be depressed to the crossed position illustrated in FIG. 2 when the ice trays are inserted in the freezing compartment of a refrigerator. It will be obvious that the stack of trays may be hand-carried by bring-ing the horizontal portions of the hails together. Thus, there is -provided in accordance with this invention an ice molding assembly for freezing a relatively large number of ice cubes in a minimum amount of space. For supporting the trays one above the other and in spaced relation to one another the trays may be formed to include a plurality of supports 22 extending upwardly from the upper edges of 4 adjacent ice molding pockets as illustrated in FIG. 3. The supports 22 comprise 4 plate members 23 disposed at right angles to one another.

Beneath each of the supports 22 and in vertical alignment therewith are web members 25 extending between the 4 corners of 4 adjacent ice molding pocket members as illustrated in FIG. 4. Each of the web members is notched slightly as indicated at 26 so that one tray may be rested on another with the plate members 23 of each support 22 engaging the notched portions of the webs 25. In this relationship the trays will not slip off one another and stack in alignment with one another. Also, the su-pports 22 space the trays apart from each other so that they cannot freeze together and so that air may circulate between trays to expedite freezing.

The pan 17 is provided with side rails 28 which are so spaced that the webs 25 in the longitudinal channels of the lowermost tray will rest thereon. This rwill prevent the stack of trays from slipping off the pau 17.

From the foregoing description it will be apparent that this invention provides an assembly or package of ice molding trays particularly adapted to be used in home refrigerators for freezing relatively large quantities of ice cubes. This eliminates the inconvenience and expense of purchasing ice cubes when relatively large quantities are required. The tray supporting and aligning means renders the assembly compact and saving of space, prevents the trays from slipping olf one another, permits circulation of air between trays, and prevents trays from freezing to one another.

The carrier structure is self-balancing and can be handled in one hand for convenient placing of the stack within a refrigerator, includes means cooperating with the lowermost tray to prevent slippage of the stack, and the handles are so arranged that they may be folded downwardlyA on to the trays after they are placed in the refrigerator thereby to eliminate excessive space requirements. p f
