(54) IMPROVEMENTS IN OR RELATING TO A SERIES OF
MUTUALLY COMPATIBLE CRATES
(71) I, PIERRE ALFRED DAVID, a citizen of the French Republic, of 18, rue
Jacquot Defrance, 54520 LAXOU, France, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement::
There is disclosed in French Patent
Registration No 72 26 351, Publication No 2 192 947, a rectangular crate characterised in that it comprises between a flat bottom and a girdle defining its upper part, lateral walls which are each perpendicular to the bottom and are formed by a plurality of oblique arms which are inclined alternately in one direction and then the other and are interconnected to the neighbouring arms by their upper and lower ends and thereby consitute upright or inverted V-shaped structures, the bases of which are fixed to the inside of the girdle, said arms and V-shaped structures of each wall being a mirror image of, or an inverted mirror image of, the corresponding arms and V-shaped structures of the opposite wall, said crate being capable of sliding and fitting into another identical empty crate which has the same orientation or capable of being superimposed on said other crate when the latter has been placed in an opposite orientation after rotation through 1800 about a vertical axis.
An object of the present invention is to provide an improved crate of the aforementioned type.
According to this invention, a rectangular openwork crate having four sides and a bottom comprises, on each of the sides thereof, arms which are inclined alternately in one direction and the other in vertical planes and are fixed in the lower part thereof outside the bottom and in the upper part thereof to the interior of a girdle surrounding the crate, said arms forming an uneven number of V-shaped structures around the crate, the V-shaped structures of two opposite sides being mirror image of each other and the V-shaped structures of the other two opposite sides being inverted mirror images of each other, and all the V-shaped structures of each side having a constant pitch measured in a direction along that side and the pitches of the V-shaped structures of two adjacent sides of the crate being different from each other.
Some examples of crates in accordance with the invention will now be described with reference to the accompanying drawings; in which:
Figure 1 is a vertical longitudinal section view in the plane AA of Figure 2 of a stack comprising two identical crates which are separated from each other by two compatible crates having a length equal to one half of that of first-mentioned crates;
Figure 2 is a vertical cross-sectional view of the same stack in plane BB of Figure 1;
Figures 3 and 4 are vertical sectional views in plane CC of Figure 4 and plane DD of Figure 3 respectively of the interior of a stack comprising a crate on which there are placed three crates which are identical to each other and are compatible with the first-mentioned crate and have a length equal to one third of that of the latter;;
Figures 5 and 6 are vertical sectional views in plane EE of Figure 6 and plane FF of Figure 5 respectively, of the interior of an assembly comprising a crate in which there are fitted two crates which are identical to each other and are compatible with the first-mentioned crate and have a length equal to one half of the latter;
Figures 7 and 8 are vertical sectional views in plane GG of Figure 8 and plane
HH of Figure 7 respectively of a crate having an uneven number of arms forming
V-shaped structures on its longer sides and on which there are stacked two crates which are compatible with the first-mentioned crate and each have a length equal to one half of that of the latter.
In the embodiment shown in Figs. 1 and 2, the lower crate 1 has a flat bottom 2 and a girdle 3 which is closed onto itself without interruption outside the four vertical side walls of the crate. These walls are formed by twenty-two arms 4 which are inclined alternately in one direction and the other and form a succession of eleven V-shaped struc tures which are arranged in the proportion of seven arms, that is to say three and a half
V-shaped structures, on the longer sides 5 of the crate and four arms, that is to say two
V-shaped structures, on the shorter sides 6.
The arms 4 are welded near their lower ends at 7, to the edge of the bottom 2 outside which the arms are arranged. The arms are also welded at their tops at 8 to the inside of the girdle 3. The girdle has an upper portion 9 which is higher than the tops 10 of the arms forming the V-shaped structures, the inner surface 11 of said upper portion being outwardly inclined.
According to a first feature of the invention, the pitch p of the arms forming
V-shaped structures has a constant value on the sides 5 of the crate and the overall length I of the crate, measured outside the girdle 3 in a direction parallel to the longer sides thereof, is a multiple of p. Also, the distances a and b between respectively, in horizontal projection, the bottom end 12 and the top end 13 of the end arms of the
V-shaped structures and the overall extremities of the sides of the crate have, when added together, a total value equal to the pitch p.Thus, if the pitch of the crate 1 has a value of 50 mm and the distances a and b are both equal to 25 mm, the overall length I of the crate 1 is as follows:
I = a + 7p + b = 25 + (7 x 50) +25 = 400
mm
On the shorter sides 14 thereof (Fig. 2), the crate 1 has an arrangement similar to that of the longer sides except that the walls 15 only have four arms 16 forming
V-shaped structures. According to a particularly advantageous arrangement of the invention, the pitch q of these arms is 60 mm and the distances between the bottom end of one end arm and the top end of the other end arm of the V-shaped structures and the transverse overall width of the crate, namely c and d, are both equal to 30 mm.
The overall width t of the crate is therefore: t = C + 4q + d = 30 + (4 x 60) + 30 = 300 mm
It must be stressed that this crate size is particularly advantageous since it may be installed with little loss of space both within the perimeter of handling pallets of 1 m x 1.2 m and within that of pallets of 0.8 m x 1.2 m, both of which are the most commonly employed pallets.
Stacked in side-by-side relation on the crate 1 are two identical crates 17 which have, on the longer sides 18 thereof (Fig. 2), four arms 19a forming V-shaped structures having the same pitch q and having the same overall size as the small sides of the crate 1 and, on the small sides thereof, three arms 19b having the same pitch p as on the large sides of the crate 1 and an overall width m equal to one half of the overall length 1 of the crate 1.
Stacked on crates 17 is a crate 20 which is identical to the crate 1 and has the same orientation. The arms 21 thereof bear on the arms 19b (Fig. 1) and 19a (Fig. 2) of the crates 17. The passage of the median arms 22 is made possible by the outward inclination of the upper portion 11 of the inner faces 23 of the girdle 24 of the crates 17.
The crates 1, 17 and 20 may of course be stacked on each other in a different order and, as they have an uneven number of
V-shaped structures, namely eleven for the crates 1 and 20 and seven for the crates 17, they can also be fitted one inside the other when they are empty and, if they are of different sizes, the smaller crates rest in the larger crates after rotation through 1800 about a vertical axis of the upper crates relative to those which received them in the stacked position.
Consequently, the invention may provide mutually compatible crates of different sizes which may be stacked or fitted one inside the other, the larger and smaller crates being capable of being stacked on each other, or in a manner to straddle each other, in any order, these different crates also being capable, whey they are empty, of being fitted one inside the other, the larger crates receiving the smaller crates on the sole condition that these different crates have on one of their sides an identical disposition of the arms and overal size.
This advantage of compatibility is essential in the practice of handling, storing and dispatch of commercial products, and in the return and re-use of the empty crates.
Indeed, the objects to be placed in each crate do not always have the same volume or the same distribution. Moreover, different users of the crates do not always have the same activities. The arrangement of crates of different but mutually compatible sizes greatly facilitates this double adaptation to the product and to the user.
It must be understood that the invention is not intended to be limited to the coexistence of only two crate sizes, one being double the other.
Thus, in the example shown in Figs. 3 and 4, a crate 25 having on the longer sides thereof eleven arms 26 forming five and a half V-shaped structures (Fig. 3) and on the shorter sides thereof six arms 27 forming three V-shaped structures (Fig. 4), receives in stacked positioned three identical crates 28, 29, 30 each having, on the small sides thereof (Fig 3), three arms 31 forming one and a half V-shaped structures and superimposed on the arms 26 of the crate 25, and, on the large sides thereof ig. 4), six arms 32 which are superimposed on the arms 27 of the crate 25 and form three
V-shaped structures.
Note that the middle crate 29 only bears on the crate 25 by the small sides thereof, the large sides thereof within the crate 25 being unsupported. This support is also lacking in respect of that one of the large sides of the crates 28 and 30 which is adjacent to the crate 29. But the triangulated assembly constituted in each crate by the bottom, the girdle and the V-shaped structures, provides sufficient strength and this arrangement presents no inconvenience in practice.
According to this example, the crate 25 may, for example, have an overall length of 600 mm., and an overall width of 400 mm and the arms may be arranged with a pitch of 50 mm, the bottom end of one end arm and the top end of the other end arm being located at 25 mm from the overall extremities of the crate in the larger dimension thereof, whereas in the width thereof the other arms 27 may be arranged with a pitch of 57 mm, the ends of the end arms being located at 29 mm from the overall extremities of the crate.
Correspondingly, the crates 28, 29 and 30 have in this embodiment an overall size of 400 mm in length and 300 mm in width.
pitch of the arms thereof being respectively 57 and 50 mm and the distances between the end bases or tops and the overall perimeter of each one thereof being respectitively 29 and 25 mm.
The modification of the invention shown in Figs. 5 and 6 differs from the preceding modification only in that the lower crate 33, which is identical to the crate 25 receives two identical crates 34 and 35 which are fitted inside the crate 33 and differ from the crates 28, 29 and 30 only in that they have on the small sides thereof five arms forming two and a half V-shaped structures. For example, the crate 33 has an overall size of 600 mm in length and 400 mm in width and the crates 34 and 35 have an overall size of 400 mm in length oand 300 mm in width.
Thus a preferred arrangement in accordance with the invention provides crates which may be employed together and have several sizes which differ from each other in the number of their arms arranged with the same pitch along their two pairs of opposite sides.
The example shown in Figs. 7 and 8 relates to a crate 36 of larger length and two crates 37 and 38 which are of a length which is one half of the latter length and in which the distance between the end base and the end top of the arms and the respective overall extremities thereof is equal to the pitch S of the arms.
This arrangement is advantageous when, owing to the heavy loads that they must support, the crates must have reinforced arms and a reinforced girdle the total thickness of which exceeds half a pitch of the arms.
This arrangement is also necessary when, in accordance with the embodiment shown in Figs. 7 and 8, the small sides of the crate 36 and the large sides of the crates 37 and 38 have an uneven number of arms (Fig. 8) and consequently the large sides of the crate 36 and the small sides of the crates 37 and 38 necessarily have an even number of arms (Fig. 7).
The invention is in no way intended to be limited to the illustrated and described embodiments. It is applicable to crates which are of any size and are made from a plastics material, metal, wood, or any other material. It permits the joint utilization of crates of different heights which may be stacked on each other in any order and are also capable of being fitted one inside the other when empty.
The upper portion of the girdle may be internally outwardly set back or cut away throughout the perimeter thereof or recessed only at the ends of two of the small sides thereof to permit the passage of the end arms of another crate which is stacked to straddle two lower crates.
The distance h (Fig. 1) between the bottom of the arms 4 and the bottom 2 of the crate is at least equal to the height k between the top of the upper portion 9 of the girdle and the tops of the arms 4 so that the crate 20 may straddle the crates 17 in the stacked position.
WHAT I CLAIM IS:
1. A rectangular openwork crate having four sides and a bottom, and comprising, on each of the sides thereof, arms which are inclined alternately in one direction and the other in vertical planes and are fixed in the lower part thereof outside the bottom and in the upper part thereof to the interior of a girdle surrounding the crate, said arms forming an uneven number of V-shaped structures around the crate, the V-shaped structures of two opposite sides being mirror images of each other and the V-shaped structures of the other two opposite sides being inverted mirror images of each other, and all the V-shaped structures of each side having a constant pitch measured in a direction along that side and the pitches of the
V-shaped structures of two adjacent sides of the crate being different from each other.
2. A crate according to claim 1, wherein the sum of the distances, measured in a direction along one side of the crate, between the ends of the end arms of that side of the crate and the overall extremities of that side of the crate is equal to the pitch of the
V-shaped structures in that side.

**WARNING** start of CLMS field may overlap end of DESC **. Note that the middle crate 29 only bears on the crate 25 by the small sides thereof, the large sides thereof within the crate 25 being unsupported. This support is also lacking in respect of that one of the large sides of the crates 28 and 30 which is adjacent to the crate 29. But the triangulated assembly constituted in each crate by the bottom, the girdle and the V-shaped structures, provides sufficient strength and this arrangement presents no inconvenience in practice. According to this example, the crate 25 may, for example, have an overall length of 600 mm., and an overall width of 400 mm and the arms may be arranged with a pitch of 50 mm, the bottom end of one end arm and the top end of the other end arm being located at 25 mm from the overall extremities of the crate in the larger dimension thereof, whereas in the width thereof the other arms 27 may be arranged with a pitch of 57 mm, the ends of the end arms being located at 29 mm from the overall extremities of the crate. Correspondingly, the crates 28, 29 and 30 have in this embodiment an overall size of 400 mm in length and 300 mm in width. pitch of the arms thereof being respectively 57 and 50 mm and the distances between the end bases or tops and the overall perimeter of each one thereof being respectitively 29 and 25 mm. The modification of the invention shown in Figs. 5 and 6 differs from the preceding modification only in that the lower crate 33, which is identical to the crate 25 receives two identical crates 34 and 35 which are fitted inside the crate 33 and differ from the crates 28, 29 and 30 only in that they have on the small sides thereof five arms forming two and a half V-shaped structures. For example, the crate 33 has an overall size of 600 mm in length and 400 mm in width and the crates 34 and 35 have an overall size of 400 mm in length oand 300 mm in width. Thus a preferred arrangement in accordance with the invention provides crates which may be employed together and have several sizes which differ from each other in the number of their arms arranged with the same pitch along their two pairs of opposite sides. The example shown in Figs. 7 and 8 relates to a crate 36 of larger length and two crates 37 and 38 which are of a length which is one half of the latter length and in which the distance between the end base and the end top of the arms and the respective overall extremities thereof is equal to the pitch S of the arms. This arrangement is advantageous when, owing to the heavy loads that they must support, the crates must have reinforced arms and a reinforced girdle the total thickness of which exceeds half a pitch of the arms. This arrangement is also necessary when, in accordance with the embodiment shown in Figs. 7 and 8, the small sides of the crate 36 and the large sides of the crates 37 and 38 have an uneven number of arms (Fig. 8) and consequently the large sides of the crate 36 and the small sides of the crates 37 and 38 necessarily have an even number of arms (Fig. 7). The invention is in no way intended to be limited to the illustrated and described embodiments. It is applicable to crates which are of any size and are made from a plastics material, metal, wood, or any other material. It permits the joint utilization of crates of different heights which may be stacked on each other in any order and are also capable of being fitted one inside the other when empty.
