Loading cage for bulk goods

Claim 2

A container for receiving and carrying heavy bulk goods dropped into the container without suffering damage, the container comprising in combination: a substantially rigid supporting framework including means defining a base for the container and first and second opposite, generally parallel side members extending upwardly from the base; a sheet of an elastomeric material extending over the length of the container and having longitudinal edges disposed adjacent the side members, the sheet between its longitudinal edges defining at least a floor of a receptacle for the bulk goods and being further dimensioned so that such portions are at all times spaced apart from the framework; a plurality of generally parallel, flexible carrying means extending between the sides of the framework and in contact with an underside of the sheet so as to support the sheet over its length transversely to the carrying means; and means anchoring the carrying means to the sides; whereby bulk goods dropped into the receptacle are received by the elastomeric sheet without contacting and thereby damaging the rigid framework while the framework, in conjunction with the sheet and the carrying means supports the weight of the bulk goods.

Claim 3

Apparatus according to claim 1 wherein the carrying means comprises a cable means supporting the underside of the sheet at spaced, longitudinally arranged intervals.

Claim 4

A container according to claim 2 wherein at least pairs of cable means are defined by endless cable means loops, and wherein the anchoring means comprises holders attached to the opposite sides of the framework.

Claim 5

A container according to claim 3 wherein the endless cable loops each define two generally parallel cable strands, and wherein the holders comprise members secured to the sides of the framework, projecting towards each other and each having upwardly open, generally semi-circular grooves, and wherein portions of the loops are disposed within said grooves.

Claim 6

A container according to claim 2 wherein the cable means comprises a plurality of generally parallel ropes constructed of a material having a higher tensile strength and a lower elastic ductility than the elastomeric material of the sheet.

Claim 7

A container according to claim 5 wherein the higher tensile strength material comprises a polyester material.

Claim 8

A container according to claim 5 wherein the higher tensile strength material comprises rayon.

Claim 9

A container according to claim 2 wherein the framework includes girders defining portions of the framework, and wherein at least one section of the sheet in the vicinity of such girders has an enlarged thickness so as to define a cushion as a protection for the frame against high impact percussions from bulk goods dropped into the container.

Claim 10

A container according to claim 8 including a plurality of recesses formed in the enlarged thickness sections of the sheet and positioned and dimensioned so as to receive the cable means therein.

Claim 11

A container according to claim 3 wherein the sheet includes suspension strips along its longitudinal edges, the suspension strips being defined by portions of the sheet having an increased thickness and engaging oppositely arranged protrusions carried by the sides of the framework.

Claim 12

A container according to claim 10 wherein the protrusions are defined by the holders for the cable loops.

Claim 13

A container according to claim 10 including clamping plates arranged along at least a portion of the longitudinal edges of the elastomeric sheet, and means biasing the clamping means against the sheet in the vicinity of the longitudinal edges thereof so as to bias and clamp the elastomeric sheet against the protrusions.

Claim 14

A container for receiving and carrying heavy bulk goods dropped into it, the container comprising: a substantially rigid supporting framework including means defining a base for the container, first and second, opposite, generally parallel, longitudinally extending beams disposed above the base, and a plurality of oppositely positioned cable holders mounted to and arranged at spaced intervals over the lengths of the beams, the holders including upwardly open recessed grooves; a plurality of endless cable loops placed into the grooves of opposing cable holders, the cables having a length so that cable strands between the holders are freely suspended and do not contact any portion of the framework; a sheet of an elastomeric material extending over a substantial portion of the length of the beams, having longitudinal edges proximate the beams and an underside facing towards the base which is engaged and carried by the cable strands so as to define a generally concave receptacle for the bulk goods which is spaced apart from the framework; whereby hard, heavyweight bulk goods dropped into the receptacle are received therein and resulting impact forces are absorbed by the sheet and by the underlying cable loops without causing damage to the framework.

Claim 15

A container for receiving and carrying heavy bulk goods dropped into it, the container comprising: a substantially rigid supporting framework including means defining a base for the container, first and second, opposite, generally parallel, longitudinally extending beams disposed above the base, and a plurality of oppositely positioned cable holders mounted to and arranged at spaced intervals over the lengths of the beams, the holders including upwardly open recessed grooves; a plurality of endless cable loops placed into the grooves of opposing cable holders, the cables having a length so that cable strands between the holders are freely suspended and do not contact any portion of the framework; a sheet of an elastomeric material extending over a substantial portion of the length of the beams, having longitudinal edges proximate the beams and an underside facing towards the base which is engaged and carried by the cable strands so as to define a generally concave receptacle for the bulk goods which is spaced apart from the framework; whereby hard, heavyweight bulk goods dropped into the receptacle are received therein and resulting impact forces are absorbed by the sheet and by the underlying cable loops without causing damage to the framework.

Claim 16

A container according to claim 13 wherein the sheet includes suspension strips along its longitudinal edges, the suspension strips being defined by portions of the sheet having an increased thickness and engaging the oppositely protruding holders for the cable loops, clamping plates arranged along at least a portion of the longitudinal edges of the elastomeric sheet, and means biasing the clamping means against the sheet in the vicinity of the longitudinal edges thereof so as to bias and clamp the sheet against the holders.
