DETAILED DESCRIPTION OF EMBODIMENTS Attention is first directed to Figs. 1 to 4A of the drawings, directed to a collapsible crate according to an example of the present disclosure, said crate generally designated 10. The crate 10 has a rectangle shape and its components are made of molded plastic material. The crate 10 comprises a base member 12 with four side walls articulated thereto and upwardly extending therefrom at an erect position, namely, a first (right) side wall 14, a second (left) side wall 16, a back wall 18 and a front wall 20. 30 - 9 - Integrally extending at a back edge of the base member 12 there is a raised back segment 24 of height Sb, and integrally extending at a front edge of the base member 12there is a raised front segment 26, wherein the raised back segment 24 is higher than the raised front segment 26 of height Sf (Sb > Sf), as will be discussed hereinafter. As can be seen, best in Figs. 2C and 2E, the side walls 14, 16 are pivotally articulated with base member 12 along a side edge of the base member 12, through hinge portions 28 integral with a bottom edge of the side walls 14 and 16, and hinge portions integral with side edges of the base member 12, thus omitting an axle type hinge, though other hinging arrangements are possible (not shown). Likewise, and as best seen in Figs. 2D and 2F, the back wall 18 is pivotally articulated along a top edge of the raised back segment 24 through hinge portions 34 integral with a bottom edge of the back wall,and hinge portions 35 integral with side edges of the raised back segment 24. The front wall 20 (not seen in Figs. 2D and 2F) is pivotally articulated along a top edge of the raised back segment 26 through hinge portions 36. The embracing hinge portions 28 and 34 are open, whereby the respective walls 14, 16, 18 and 20 can be detached from the base member 12.As can further be seen in Figs. 2D and 2F, the hinge arrangement of the back wall and the front wall 20 is such that at the erect position a bottom, outside facing inverted L-shape portion 40 of the back/front wall 18, 20 bears over an upright shoulder portion extending from the raised back segment 24. This arrangement supports the walls 28 and 20 at an upright position and prevents their pivotal displacement over 90°. It is noted that the side walls 14 and 16 are of equal length, and the front wall is shorter than the back wall 18, however wherein at an erect position the four walls extend to the same height, with an equally leveled, coextending, continuous top edge 19. Accordingly, and as can be seen in Fig. 2B, the height difference between the height hb of back wall 18 and height hf of the front wall 20 is equal to the difference between height Sb of the raised back segment 24 and height Sf of the raised front segment 26 (hb-hf=Sb-Sf). Each of the four walls is configured with an opening 33, serving as a carrying handle for transporting the crate. Furthermore, Attention is now directed to Figs. 4A, 6A, 6D, 8A, illustrating an interconnecting arrangement between the side edges 45 of the two side walls 14 and 16, and the respective - 10 - neighboring side edges 47 of the back wall 18 and front wall 20. Accordingly, the side edges 45 are configured with lateral L-shaped projections 48, outwardly facing, and configured for arresting within respective openings 50 disposed along side edges 47 upon displacing the respective side wall into an erect position, as will be discussed hereinafter.Also noted (best Figs. 6A, 6C, 6D and 7B), side edges 47 of the back wall 18 and the front wall 20 are configured with a longitudinal laterally projecting edge 54, wherein at the erect position said edge 54 bears over an edge portion 45 of the neighboring side wall.As mentioned hereinabove, the four walls 14, 16, 18 and 20 are pivotally articulated to respective portions of the base member 12, wherein said walls are displaceable between an erect position (Figs. 1 to 4A and 10A to 10C), and a fully collapsed position (Figs. 9A to 9E and 11F). For retaining the crate 10 at an erect, stable position, there is configured a locking mechanism configured for arresting engagement side edges of a side wall and neighboring side edges of the front wall and back wall, respectively. Accordingly there is provided a locking bar 60 (seen isolated in Figs. 5AS and 5B) comprising cylindrical portions snapingly received within a locking bar receiving groove 65 disposed across a top portion of each of the side walls 14 and 16. The locking bar 60 comprises at each end thereof a radially projecting locking tab 66, extending beyond a side edge portion 45 of the side wall 14, 16, and a handle-shaped locking bar manipulation portion 68 for rotatably manipulating the locking bar about a longitudinal axis thereof, between a locked position and an unlocked position. The locking tab 66 has a first axis X1 and a second axis X2(Figs. 5A, 5B, 6C and 7B) intersecting said first axis X1, wherein the first axis is longer than the second axis (X1 > X2). The locking bar 60 is rotatable over the longitudinal axis about at least 90° between a locked position, and an unlocked position, as will be discussed hereinafter.Respectively configured at a top side edge portion 47 of each of the back wall and the front wall 20 there is a locking tab arresting portion 70 configured with locking tab path (along arow 72) and a locking tab obstruction arrangement, namely a top wall obstruction 76 and a bottom ridge 78, with gliding surfaces 82 to facilitate smooth displacement of the locking tab 66 into the locking tab arresting portion 70. The distance - 11 - D at the locking tab path between the obstruction members 76 and 78 is greater than the length of X2, though lesser than the length of axis X1 (X2 >D> X1).The arrangement is such that at an erect position an opening of the locking tab path 72 extends opposite the locking tab 66 and wherein at the unlocked position (Figs. 7A and 7B) the locking tab 66 is disposed horizontally, i.e., the first axis X1 is disposed horizontally, wherein the locking tab 66 is free to displace along the locking path 72through the opening and into the locking tab arresting portion 70. However, at the locked position (Figs. 6B and 6C) said first axis X1 of the locking tab 66 intersects the locking tab path 72, wherein once received within the locking tab arresting portion 70 the locking tab 66 is prevented from displacement away as it is obstructed by the obstruction members 76 and 78.Furthermore, the locking bar 60 can be arrested at the locked position by a snap-lock arrangement comprising ridges 83, 85 (at the manipulation handle portion 68) and 87, snapingly arrestable by corresponding ridges at the side wall for distinct displacement of the locking bar 60, and wherein the ridge 85 is arrested within the opening 33 (carrying handle) by lip 89 thereof (Fig. 3), for arresting the locking bar 60 at the locked position. Noticeably, at the locked position the manipulation handle portion 68 of locking bar 60merges within the opening 33 of the side wall, such that it constitutes part of the carrying handle when the crate is displaced.Figs. 9A to 9E illustrate the crate 10 according to the present disclosure at a collapsed position, wherein the first side wall 14 and the second side wall 16 are disposed coplanar and flush over a top face 13 of base member 12, the front wall 20 resting flat and flush over the side walls 14 and 16, and the back wall 18 resting flat and flush over a portion of the front wall 20, wherein the walls 14, 16, 18 and 20 and the base 12 are partially disposed. If, however, the height of front wall plus the height of back wall would be equalto or less than the width of the side walls (not shown) than the front wall and back wall could extend coplanar over the side walls 14 and 16, at the collapsed position. It is seen that thickness of the base member 12 plus thickness of a side wall 14, plus the thickness of the back wall 18 plus thickness of the front wall 20 is equal to the height Sb of raised back segment 24, and the thickness of base member 12 plus the - 12 - thickness of a side wall 14, 16 plus thickness of the front wall 20 is equal to height Sf of the raised front segment 26.Figs. 10 and 11 exemplify consecutive steps for erecting/collapsing the crate 10of the present disclosure. Taking for example that the crate 10 is at its erect, locked position (Figs.10A and 11A), a first step is unlocking the locking mechanism by pivotal/swinging displacing the locking bar manipulation portion 68 outwards, in direction of arrow 90 (Figs. 10B and 10C), overcoming the snaping ridge 78. By doing so, the locking tab 66 displaces into the unlocked position (Figs. 7A and 7B) facilitating collapsing the side walls 14 and 16 towards one another in direction of arrow 94 (Figs. 11B to 11C) until they rest coplanar, flush over the base member 12 (Fig. 11D). Then, front wall 20 is pivotally collapsed in direction of arrow 96 (Fig. 11E) until it comes to rest flush over the side walls 14 and 16, followed by pivotally collapsing of the back wall in direction of arrow 98 (Fig. 11E) until it comes to rest flush over the front wall 20, wherein the crate assumes flat, compact position (Fig. 11F).Erecting the crate 10 takes place in a reverse sequence of operations. 15
