13 Claims. I
The present invention relates to ice tray grids and more particularly to ice tray grids which are removable from an ice tray, and which may be readily operated to secure the release of the .ice cubes therefrom.
. The problem of-freeing ice cubes from a tray in which they are frozen in a conventional type of mechanical refrigerator is one which has been long resent in this art. The attempts to solve the problem have generally taken one of two directions. First, the provision of a grid formed of a resilient material, such for example as rubber or the like, which may be distorted to break the bond between the grid and the cubes, and thus to free the cubes from the grid. Second, the provision of a grid having rigid partitioning members, certain of which are movable relative to the others for the purpose of breaking the adhesion between the ice. cubes and the rigid elements of the grid construction.
In both general forms of the prior grids the grid'mechanism and the ice when frozen presents a rigid mass in which the grid, whether resiliently flexible or whether mechanically united for movement of one rigid section relative to the other is held immobile in the ice block. In both types of grids there is a mechanical connection which imparts structural rigidity to the grid member and this rigidity is further increased when the ice is frozen therein. In the case of the resilient types of grids, the resiliency of the material is much impaired and frequently lost at the low temperatures necessary for the freezing of the ice. The adhesion of the ice to the various portions of the rigid grid members in the type utilizing rigid members which are movable relative to one another, renders these grids immobile to the extent that they are for all practical purposes a .rigid grid structure at the beginning of the ice In order to satisfactorily.
removing operation. break such grids from the ice cubes, it is necessary to apply a force thereto of sufficient magnitude to move oneof the gridmembers relative to the other grid members, and having thus initiated the ice-freeing movement, to then fol- .low it with the progressive movement of other of the grid members. to inthis art as a progressive flow of power".
This is frequently referred As distinguished from previously known types wof'gridathe grid of the present invention l 00mposed of a plurality of separate elements freely joined together in such a manner that a sudden force applied to any grid member is transmitted throughout the frozen grid and i-cetblock to provide an instantaneous releaseof all ofthe ice cubes from the grid.

It is a further object of the present invention to provide an ice tray grid constructed of a plurality of separate rigid grid elements flexibly united for relative movement of any part relative to every other part in all directions, the crosspins and the longitudinal members having substantially complete freedom of movement in any direction within predetermined limits whereby a shock transmitted to the grid while frozen in lrissiormins apart of th1speciflcation wherein arate members forming an articulated longitudinal divider partition, separate members forming articulated transverse members of the grid, and an elongated assembly pin loosely connected with each of said separate members.
