Definitions

  • the present invention relates to crates and, in particular, it concerns a knock-down crate in which the walls can be stored in a recess in the base, and a corresponding method for transporting produce.
  • molded polymer containers are chosen for their light weight, robustness and long usable lifetime.
  • polymer crates are often molded in a single piece. As a result, however, they occupy the same volume when transported empty on a return journey as when full on an outbound journey. This extremely inefficient use of space is very costly.
  • knocic-down crates While offering more efficient use of volume, knocic-down crates generally suffer from a number of disadvantages. Specifically with respect to crates which disassemble into separate elements, the base and the sides once separated are generally much less convenient to handle. Furthermore, the number of individual elements which must be handled is greatly increased, and considerable extra labor may be required for packing individual bases and sides compactly for volume-efficient transportation to the next point of use.
  • DE29703221U discloses a plastic, cube-shaped container having a base structure with a base plate and the side and end walls being connected by toothed bars.
  • a dovetailed teeth widens out towards the container's exterior, and the gaps between the teeth narrow. The teeth and gaps interlock so that they can swivel.
  • the base structure is hinged to the side walls and to the base structure by means of hinges.
  • the side walls are attached to base strips especially.
  • the base strip has a 13-shape recess into which fits a protuberance on the wall and which forms corner uprights.
  • the base structure has pallet feet and fork openings.
  • a two-part cover has facing edges in the form of dovetailed, toothed bars.
  • the present invention is knock-down crate and a corresponding method for transporting produce.
  • a knock-down crate comprising: (a) a base having a length, a breadth, and an upper surface; and (b) a first pair of sides associated with the base and configured to alternate between a first deployment parallel to the length and a storage deployment, and a second pair of sides associated with the base configured to alternate between a first deployment parallel to the breadth and a storage deployment, wherein the upper surface of the base features an elongated recess extending substantially the entirety of the length, the recess being sized for receiving at least one of the first and second pairs of sides, such that, when the first and second pairs of sides are deployed in the first deployment, the base and the sides define a four-sided crate with the recess contributing to an internal volume of the crate, and when the first and second pairs of sides are deployed in the storage deployment, at least one of the first and second pairs of sides is receivable so as to be substantially contained within the recess for compact transportation.
  • association of the first and second pairs of sides with the base includes hinged interconnection of at least one of the first and second pairs of sides with the base such that the at least one of the first and second pairs of sides is rotatable between the first deployment and the storage deployment.
  • both the first and second pairs of sides are hingedly interconnected to the base.
  • one of the first and second pairs of sides is receivable so as to be substantially contained within the recess and the other of the first and second pairs of sides covers the recess.
  • the at least one of the first and second pairs of sides having the hinged interconnection includes at least the first pair of sides, and the first pair of sides is hingedly interconnect so as to allow each side of the pair to move away from an edge of the base when deployed in the recess.
  • the hinged interconnection allows a base region of the each side to descend into a depth of the recess, so as to allow each of the sides of the first pair to lie parallel to the upper surface.
  • At least one of the first and second pairs of sides includes attachment features configured so as to disengagably attach adjacent sides one to another when the first and second pairs of sides are deployed in the first deployment.
  • the pair of sides that covers the recess folds such that each side of the pair folds over no more than half of one of the length and the breadth.
  • the other of the first and second pairs of sides includes a foldable extension portion along a top region of at least one side of the pair of sides.
  • the length is substantially equal to the breadth.
  • the elongated recess is a closed-ended recess terminating at two end walls.
  • each side of one of the first and second pair of sides has a length no greater than a length of the closed-ended recess.
  • association of the first and second pairs of sides with the base is a detachable engagement such that the first and second pairs of sides, when detached from the base, are receivable so as to be substantially contained within the recess to attain the storage deployment.
  • the length is substantially equal to the breadth.
  • first pair of sides and the second pair of sides are interchangeable.
  • the elongated recess is an open-ended recess extending the entirety of the length.
  • At least the second pair of sides each features a downwardly projecting tab configured to substantially close an end of the open-ended recess when the side is engaged with the base.

  • the base and the first and second pairs of sides are all formed primarily from molded plastic material.
  • the base has a pair of elongated channels extending parallel to the length for receiving tines of a forklift mechanism.
  • a major part of the recess lies between the elongated channels.
  • a method for using a knock-down crate to transport produce from a loading location to an unloading location comprising the steps of:
  • upper and lower edges of the sides and upper and lower peripheral regions of the base are formed with complementary alignment projections and recesses
  • the method further comprising: (a) stacking the crate when in the crate configuration with other similar crates such that the alignment projections and recesses on the upper edges of the sides and on the lower peripheral region of the base serve to align the crate with the other similar crates placed above and below the crate; and (b) stacking the crate when in the knock-down configuration with other similar crates such that the alignment projections and recesses on the upper and lower peripheral regions of the base serve to align the crate with the other similar crates placed above and below the crate.
  • the present invention is a knock-down crate in which the walls can be stored in a recess in the base for compact and convenient handling when unloaded, and a corresponding method for transporting produce.
  • knock-down crates The principles and operation of knock-down crates according to the present invention may be better understood with reference to the drawings and the accompanying description.
  • the crate of the present invention includes a base associated with four sides.
  • the principles of the present invention will be discussed herein with regard to three basic embodiments.
  • the first embodiment, in which the base and the sides are hingedly interconnected, will be discussed regarding Figures 1-11E .
  • the second and third embodiments, in which the sides are detachably engageable with the base, will be discussed with regard to Figures 12A-18 and 19-23 , respectively.
  • FIG. 1 shows a first preferred embodiment of a knock-down crate, generally designated 300, constructed and operative according to the teachings of the present invention.
  • crate 300 is formed from a base 312 and two pairs of sides 314 a and 314 b , 316 a and 316 b all four of which are hingedly interconnected to base 312.
  • sides 314 a and 314 b are interconnected to base 312 by a non-limiting example of a double hinge 37O, as will be discussed in detail below the regard to Figures 11A-11E .
  • Sides 316 a and 316 b are hingedly interconnected to base 312 by hinge 350 that, in this non-limiting example, extends for substantially the entire length of each side. It should be noted that substantially any suitable hinge arrangement is within the scope of the present invention.
  • An upper surface 318 of base 312 features an elongated recess 320 extending substantially, the entirety of a length L of base 312 and sized for receiving sides 314 a and 314 b in a storage deployment. Once sides 314 a and 314 b are stored in recess 320, sides 316 a and 316 b are folded inwardly to cover sides 314 a and 314 b , recess 320 and the exposed portions of upper surface 318 of base 312. It should be noted that the word "inwardly” is used herein to refer to movement toward the center of the crate.
  • Figures 2-10 illustrate steps for deploying the two pairs of sides 314 a and 314 b , 316 a and 316 b into their respective storage deployments.
  • any attachment feature that secures one of the sides to an adjacent side is disengaged.
  • the illustration here shows handles 322 configured in sides 314 a and 314 b , however, substantially any disengageable attachment configuration, as discussed below with regard to a second and third preferred embodiments, may be used.
  • side 314 b is folded inwardly, as seen in Figure 3 , until it is received into recess 320, as seen in Figure 4 .
  • Side 314 a is then disengaged from the adjacent sides 316 a and 316 b , and folded inwardly, as seen in Figure 5 , until it is received into recess 320 and resting on side 314 b , as seen in Figure 6 . It should be noted that this sequence may be reversed and side 314 a may be stored away first with 314 b resting on top.
  • side 316 b is folded inwardly, as seen in Figure 7 , until it is resting on the upper surface 318 of the base 312, as seen in Figure 8 .
  • side 316 b is preferably no longer than one-half (1 ⁇ 2L) of the length L of base 312 in order to add not more than one side thickness to the thickness of the base in the overall thickness of the storage configuration of the crate.
  • sides 316 a and 316 b may need to be longer than one-half (1 ⁇ 2L) of the length L of base 312.
  • the present invention provides a foldable extension 352 hingedly attached along the top edge of at least one of sides 316 a and 316 b .
  • the foldable extension 352 is attached by hinges 354, and is folded into the associated side during the folding process of the side.
  • a transverse recess 352 a is preferably provided in the base and/or folded sides to accommodate the foldable extensions without adding significantly to the thickness of the folded configuration.
  • Side 316 a is then folded inwardly, as seen in Figure 9 , until it is resting on the upper surface 318 of the base 312, as seen in Figure 10 .
  • both sides 316 a and 316 b are in the storage deployment, substantially all of the upper surface 318 of the base 312, recess 320, and sides 314 a and 314 b are covered by sides 316 a and 316 b .
  • sides 314 a and 314 b In order for sides 314 a and 314 b to be deployed in recess 320 that is located between channels 326, as discussed below, it is necessary for sides 314 a and 314 b to move away form the edge of base 312, and preferably also to be able to descend at least partially into the depth of recess 320. Further, it is also preferable that the base region of the side, that is the region of the side that abuts base 312, descend into the depth of recess 320, so as to allow each of the side to lay parallel to the upper surface 318.
  • FIGS 11A-11E illustrate a non-limiting preferred hinged configuration for such interconnection of base 312 and sides 314 a and 314 b , and steps for deploying sides 314 a and 314 b into their respective storage deployments.
  • hinge configurations may include, but are not limited to, a slideable hinge, and a hinge pin associated with a slot.
  • hinge bracket 370 provides rotation about two axes of rotation, 360 and 362.
  • rotation about axis 362 allows the bottom edge of side 314 a to move away from the edge of base 312 in order to reach recess 320, as seen in Figure 11 .
  • Rotation about axis 360 allows side 316 a to lay flat when received in recess 320, as seen in figure 11 C .
  • the "L" shape of bracket 370 allows the base region of the side to descend into the depth of recess 320, so as to allow each of the sides 314 a and 314 b to lay parallel to the upper surface 318.
  • Crate 300 is preferably configured for handling by standard pallet handling equipment.
  • base 312 preferably has a pair of elongated channels 326 extending parallel to length L for receiving tines of a forklift mechanism (forklift, pallet carrier etc.).
  • Channels 326 typically extend along the entirety of length L, allowing insertion of tines from either end of the crate.
  • crate 300 may be considered to have a thin base 312 in the region of recess 320, with locally raised regions to provide the volume required for channels 326. It will thus be understood that the usable volume of the inside of the crate is fully maximized by making all volume other than that required for channels 326 available for loading with produce.
  • FIGS 12A-18 show a second preferred embodiment of a knock-down crate, generally designated 10, constructed and operative according to the teachings of the present indention.
  • crate 10 is formed from a base 12 and a set 14 of sides 16 a , 16 b , 16 c and 16 d .
  • An upper surface 18 of base 12 features an elongated recess 20 extending substantially the entirety of a length L of the base and sized for receiving set of sides 14.
  • the sides are configured to be detachably engageable with base 12 with a first pair 16 a and 16 c parallel to the length L of base 12 and a second pair 16 b and 16 d parallel to a breadth or width W of base 12 such that, when sides 16 a , 16 b , 16 c and 16 d are engaged with base 12, the base and the sides define a four-sided crate 10 as shown in Figure 13 with recess 20 contributing to an internal volume of the crate.
  • the set 14 of sides 16 a , 16 b , 16 c and 16 d are received so as to be substantially contained within recess 20 to form the knocked-down configuration of Figure 14 for compact transportation.
  • the crate of the present invention offers profound advantages over conventional knock-down crates. Specifically, in the assembled configuration of Figure 13 , recess 20 contributes significantly to the usable internal volume of the crate, thereby maximizing transport volume. In the knocked-down state of Figure 14 , all parts of the crate are configured in a single compact block which is easily handled and can be efficiently stacked with other similar crates to ensure minimum volume for return transportation or storage of the crate when not in use.
  • the crate is a square crate, i.e., that length L is substantially equal to breadth W. In most preferred cases, all four sides are then made interchangeable such that the user can assemble the crate with each side located arbitrarily along any edge of the base.
  • each of sides 16 a , 16 b , 16 c and 16 d includes attachment features 22, 24 for attachment to two adjacent sides.
  • Figure 15 illustrates two interconnected sides 16 c and 16 d , with their available attachment features clearly visible.
  • the attachment features are shown here schematically as complementary rectangular-section interlocking tabs with through-bores for receiving a bolt element to lock the sides together and to the base.
  • attachment features 22, 24 are further configured such that pairs of the sides are doubly-interlockable to form a unit 14 a with the pair of sides associated in close parallel relation.
  • Figures 16A and 16B show such a unit 14 a prior to and after interconnection.
  • Figure 17 shows a cut-away view of crate 10 partially assembled with one unit 14 a stored in recess 20. Two such units together make up an easily handled set 14 of sides for insertion into recess 20 as shown in Figure 18 .
  • a locking arrangement may be provided to retain set of sides 14 within recess 20 to ensure that the set of sides do not become dislodged during handling.
  • at least one locking element used for interlocking the sides when assembled also functions to selectively lock the set of sides within recess 20 when in the knock-down configuration.
  • base 12 and sides 16 a , 16 b , 16 c and 16 d are all formed primarily from molded plastic material. It should be noted, however, that implementations of the crate structure described using materials other than molded plastics also fall within the broad scope of the present invention.
  • the various components of the crates of the present invention are illustrated here schematically and simplistically for clarity of presentation. The geometrical patterns shown here on the sides of the crates are non-functional and are included merely to facilitate visual differentiation between the inward-facing and outward-facing surfaces. It will be understood by one ordinarily skilled in the art that the various components will typically be implemented with various structures of reinforcing ribs and/or other functional or decorative features which do not per se constitute part of the present invention.
  • the base and walls may be made either solid or with drainage and ventilation openings, as is known in the art.
  • Crate 10 is preferably configured for handling by standard pallet handling equipment.
  • base 12 preferably has a pair of elongated channels 26 extending parallel to length L for receiving tines of a forklift mechanism (forklift, pallet carrier etc.).
  • Channels 26 typically extend along the entirety of length L, allowing insertion of tines from either end of the crate.
  • crate 10 may be considered to have a thin base 12 in the region of recess 20, with locally raised regions to provide the volume required for channels 26.
  • the usable volume of the inside of the crate is fully maximized by making all volume other than that required for channels 26 available for loading with produce. Furthermore, since the sides are stored between the regions of base 12 containing channels 26, nothing overlies the regions of the base 12 containing channels 26 in the collapsed state, making the height of the crate in its collapsed state significantly less than that of "fold-down" crates of similar dimensions.
  • elongated recess 20 is a closed-ended recess terminating at two end walls 28.
  • the length of recess 20 is slightly less than the external length L of base 12.
  • each side preferably includes one corner portion of the assembled crate, with part of the adjacent side or at least engagement features for the adjacent side extending laterally from the corner portion.
  • the length of each side is less than the external length dimension of the assembled crate by the thickness of one corner portion, preferably at least equal to a thickness of the crate side.
  • end walls 28 have a thickness no more than about half the thickness of sides 16 a , 16 b , 16 c and 16 d , the sides can be accommodated within recess 20.
  • FIG. 19A-21 there is shown a third preferred embodiment of a crate, generally designated 100, constructed and operative according to the teachings of the present invention.
  • Crate 100 is structurally and functionally similar to crate 10 described above.
  • features of crate 100 analogous to those of crate 10 are labeled with reference numerals greater by 100 than the numeral used for the analogous feature of crate 10.
  • Crate 100 differs from crate 10 primarily in that recess 120 is here an open-ended recess extending the entirety of length L.
  • recess 120 is here an open-ended recess extending the entirety of length L.
  • at least one pair of sides 116 b and 116 d each features a downwardly projecting tab 130 configured to substantially close an end of recess 120 when the side is engaged with base 112 as shown in Figure 20 .
  • base 112 features an engagement indentation 132 ( Figure 8A) across each end of recess 120 with which downwardly projecting tabs 130 engage when assembled to provide mechanical support to the tabs.
  • the crates of the present invention employ four interchangeable si des, thereby allowing a user to assemble the crate with each side engaged along an arbitrarily chosen edge of the base.
  • interchangeable refers to sides having functionally equivalent features to the extent that inadvertent swapping of two sides does not significantly impact the function of the assembled crate. Interchangeability does not necessarily imply that the sides are identical or indistinguishable.
  • interchangeability of the sides may be achieved by providing a pair of slots 134 extending parallel to length L and configured for receiving downwardly projecting tabs 130 of the sides deployed parallel to length L.
  • the engagement of tabs 130 within slots 134 also adds structural strength to the assembled crate.
  • tabs 130 are most preferably slightly thinner than the main upper portion of the sides and slightly set back from the plane of the outer surface of the side.
  • tabs 130 may have a thickness equal to that of the main upper portion of the sides, the tabs being received in a corresponding external recess formed in the external surfaces of the base parallel to the length L.
  • crate 100 In all other respects, the structure and function of crate 100 will be understood by analogy to that of crate 10 described herein.
  • the sides and base are preferably configured to allow stacking of the crate with other similar crates in both the assembled crate configuration and the knock-down compact configuration.
  • the upper and lower edges of sides 16 a , 16 b , 16 c and 16 d , and upper and lower peripheral regions of base 112 are preferably formed with complementary alignment projections 200 and recesses 202 ( Figure 24A ).
  • Alignment projections 200 and recesses 202 are positioned and configured such that, when the sides are engaged with the base to form the four-sided crate ( Figure 24B ), alignment projections 200 and recesses 202 on the upper edges of the sides and on the lower peripheral region of the base serve to align the four-sided crate with similar crates (not shown) placed above and below the crate, and when the sides are received within recess 20 ( Figure 24C ), alignment projections 200 and recesses 202 on the upper and lower peripheral regions of the base serve to align the base with similar bases (not shown) placed above and below the base.
  • the crate is deployed in its deployed "crate configuration" and loaded with produce at a loading location.
  • the produce lies within the elongated recess 20, thereby contributing to the total volume of produce which can be transported within the crate.
  • the produce is unloaded from the crate and the crate is disassembled and the walls stored in the recess to produce the "knock-down configuration" as shown in Figure 23 .
  • the crate is then compact and conveniently handled, with the four sides located substantially within elongated recess 20, for transport to a next loading location.
  • the crate is stacked with other similar crates when in the crate configuration such that the alignment projections and recesses on the upper edges of the sides and on the lower peripheral region of the base serve to align the crate with the other similar crates placed above and below the crate, and is stacked when in the knock-down configuration with other similar crates such that the alignment projections and recesses on the upper and lower peripheral regions of the base serve to align the crate with the other similar crates placed above and below the crate.
