Description

There is the crate of continuous stiffened members

Background technology

Embodiments of the invention relate to a kind of crate (crate in order to hold product, crate) or container, more particularly, embodiments of the invention relate to a kind of plastics crate, this plastics crate is provided such as, in order to hold and/or to transport food, fruit, vegetables, meat and analogue.

Crate in order to deposit and to transport product (such as fruits and vegetables) is widely used in market.These crates are both light and stable, and make them be applicable to these results products are delivered to client by field band.Such as, with regard to tropical fruit (tree) such as banana, normally gather in these products when it is not yet ripe, and be packaged in these crates for follow-up shipment and conveying.In this route, these fruit are ripe if having time.In addition, other fruit is as apple or analogue, or vegetables are as lettuce or analogue, and meat or egg etc. also can be placed in these crates at the person of producing place, and uses these crates to transport.

Before shipment, these crates filled are gone up push-down stack mutually and each other and come on two supporting plates, then these supporting plates can be transferred into respective load transfer device together usually.Usually, a specific Cross-Stack technology can be used, such as a kind of " five fall configuration (5-downconfiguration) ".Five fall in configuration at this, five crates can by one-tenth one rectangular array disposed adjacent one another, and make wherein two alongst shape is in a row, and other three are in a row along Width shape.It is when carrying out these crates of storehouse in this way that this kind is furnished with a problem, and three crates that broad ways shape is in a row can with their the longer sidewall abutting against two crates in a row of shape along its length compared with short end wall.Therefore, the power acted on the sidewall of the crate arranged along its length can be higher, especially at the middle section place of the sidewall of the crate arranged along this length direction.This may cause the damage of these crates when transport or storehouse.

Above-mentioned crate can be plastics crate, and it comprises the opposite end walls and opposing sidewalls of stretching out from the bottom with overall rectangular shape.These crates also can be formed by other material, as timber, cardboard or analogue.These crates are also referred to as folding crate, and this means these end walls and sidewall can be folded down to direction bottom this.This allows that these sky crates are transported with their folded state, such as, to field place, also can directly be put into respective crate this place crop by results.This tolerable uses minimum transmission capacity to transport the folding crate of big figure, and in a kind of mode of economy, folding crate band is delivered to required place.Also have the crate of differing heights, namely some crate have by bottom this with multiple walls that the first distance extends, and other wall upwards can extend with the second distance being greater than this first distance.The height of these crates, when folding, determines according to the product that will be received wherein also transport.There is the structure of the crate of these foldable wall, may make these sidewalls can be overlapping when to be folded down to bottom this.In the case, for obtaining a minimum possibility height, traditional crate needs the particular order of its each wall portion folding.Such as, first, Liang Ge end wall branch is folded on bottom this, and then first meeting of these two sidewalls is folded downwardly to adhere on the end wall of these lower foldings, and then second of these sidewalls can be folded downwardly again.These each sidewalls can be obtained and can extend beyond this highly without any part by the minimum constructive height of the crate that is configured to make this folding in such manner.

But, the method is not good enough, because it needs the user of crate to know, how folded this crate is, namely, this each wall portion must be come to fold in the correct way, otherwise can not obtain this minimum constructive height, again and, the element of these wall portion may extend beyond this minimum constructive height, and hinders these to amount to the appropriate storehouse of crate.That edge bottom this provides a protrusion upwards to extend by bottom this with a preset distance to a solution of this problem, guarantee the independence of these two folded modes of sidewall thus, even if at " the worst ", these sidewalls do not have any portion can stretch out above the top of this protrusion yet.Although this can solve the problem of the height extending beyond this folding crate about some part, it can increase again the height of this folding crate at the same time, and thus will limit can by the overall number of the folding crate of storehouse and transport.Although when only seeing single crate, this is a seemingly very little problem, but people must consider following situation: there are these a large amount of crates folded, and be placed on respective supporting plate and be transported, and the height that this protrusion has increase is described above, may cause the loss of the transport capacity of about 15%.

Above-mentioned crate is folding, comprises a lockout mechanism further, and this lockout mechanism can guarantee these sidewalls and end wall being fixedly connected with when the non-folded state of this crate.Meanwhile, a maneuverable mechanism must be provided, so that when all products have been removed and this crate will be transported back supplier place (such as cleaning) and need this crate folding, in order to discharge this breech lock (latch).The crate therefore with foldable wall comprises releasing mechanism, this release mechanism acts on latch component for this breech lock of release, and thus tolerable each sidewall folding downwards.Such as, these sidewalls can comprise the respective holder being formed in its lateral margin place, and a lateral margin is adjacent to these end walls.In these end walls, moveable bolt lock mechanism can be provided, such as, when by each cornice to its stand up position time, have a clasp (hook) can be biased in one downward to and engage with the holder in this sidewall.Such as, when a sidewall is moved to this stand up position by base portion position, this clasp can the element of this sidewall by time raise, then, due to this biased downward, this clasp can be contained in this holder.When utilizing this releasing mechanism to discharge this breech lock, this clasp can be raised, and these latch components can be released off, and this sidewall can be folded down to the direction bottom this once again.

These mechanisms provide a kind of maneuverable mode to come for untiing the folding of this crate, but generally speaking, these mechanisms are configured to make it all can activated (actuated) in any time of this crate in non-folded state.This is disadvantageous, and because it also can work as multiple crate by storehouse, such as, time on a supporting plate, tolerable activates this releasing mechanism.In the case, due to vibrations or the operation of mistake, the bolt lock mechanism stacking one or more crate in (stack) at this may activated, and the wall elements that release is corresponding, causes this entirety to stack to become unstable.In the worst case, this may cause this avalanche stacked, because stack one or more crate interior and possibly cannot reoffer required stability at this and carry out the crate of support stack on its top.

As mentioned above, these crates can be used to transport food, as veterinary antibiotics and meat or analogue.These products may need cooling, therefore preferably can provide refrigerant fluid in the inside of this crate, as frozen water or analogue, to guarantee that these goods keep fresh and/or are in proper temperature.Although these crates, generally speaking, opening is had to allow wind circulation at sidewall and bottom, but it is inner that these openings may be not enough to allow sufficient refrigerant fluid flow into this crate, such as, when using frozen water, ice particulate may be had in this liquid stream, these particulates will not established by these hole supplying air circulation, and in fact may keep off these holes of plug, and hinder this liquid to reach the inside of this crate.

Therefore, though the hardening structure on the sidewall of this crate shown in Fig. 2 (a) is well available, when these crates layout parallel to each other, if these crates 100a-100c is disadvantageous under the deployment scenarios of crate as shown in Figure 3.

Therefore, according to the embodiment of the present invention about first aspect, a stiffened members revised can be provided.Fig. 4 illustrates an embodiment of this stiffened members revised.Fig. 4 illustrates that this sidewall 108a has the stiffened members 126 of this correction.Similarly, this stiffened members 126 have parallel and be adjacent to this first lateral margin 118 extend Part I 126a.One Part II 126b of the stiffened members 126 of this correction parallel and be adjacent to this second lateral margin extend.The stiffened members 126 of this correction is also a continuous print stiffened members, understands by the corner, lower-left of this sidewall 108a along this lateral margin 118, and along this upper limb towards the second lateral margin, then extend continuously down to the lower right corner of this sidewall 108a.The stiffened members 126 of this correction comprises a U-shaped portion further at a middle section of this sidewall 108a and divides 128.This U-shaped portion divides 128 to comprise two vertical stiffened members part 126c and 126d, and it is substantially parallel to aforesaid part 126a and 126b.Further, some 126e is set as and is adjacent to this lower edge 124.The left side outside the middle body of this sidewall 108a and right-hand component, the stiffened members 126 of this correction comprises two part 126f and 126g, and these two parts are disposed adjacent in this upper limb 122.As previously mentioned, the stiffened members 126 of this correction is a continuous member, and namely all each several part 126a-136e connect each other, and form this continuous member in a mode as shown in Figure 4.These air extractor vents 110 are arranged on the left side and the right-hand component of this sidewall, and this stiffened members is arranged on these air extractor vents and lateral margin 118 and 120, between this middle section and this upper limb 122 respectively.In this middle section, these air extractor vents are provided with a stiffened members between this left side and right-hand component and this lower edge 124.

The layout of Fig. 4 can be the hardness that this sidewall 108a and this middle body provide increase, avoids damaging thus when such as above-mentioned when multiple crate is fallen with five shown in Fig. 3 configuration carrys out storehouse.

The embodiment of this first aspect is not limited to the configuration shown in Fig. 4, and other different configuration of the stiffened members 126 of this correction also can be provided.Now with reference to Fig. 5 (a) to (c), these embodiments are described.Each figure schematically illustrates this sidewall 108a, and also illustrates for the stiffened members 126 revised with reference to Fig. 4.In the embodiment shown in Fig. 5 (a), the U-shaped portion that this sidewall comprises the stiffened members of two these corrections is divided, and they all can extend omnidistance towards this lower edge.Fig. 5 (b) illustrates the schematic diagram of a different embodiment, and according to this example, the U-shaped portion of this stiffened members is divided only downwardly can extend the half height of this sidewall 108a by this lower edge.Fig. 5 (c) illustrates the schematic diagram of another embodiment, and it uses three U-shaped stiffened members parts with difference " degree of depth ", and namely they can extend towards the lower edge of this sidewall with different amounts.

Although the above embodiments point out that U-shaped stiffened members part extends towards this lower edge, please note that the present invention is not limited to these embodiments.Such as, and according to other embodiment, to leave in the region of these lateral margins the stiffened members part extended bottom towards this at one of this sidewall and also can be different, this part can be V-arrangement, or if necessary, also can have an asymmetric shape.

Second aspect-" moveable hinge "

Below, the embodiment of the present invention according to second aspect will be described.This second aspect relates to the folding of the sidewall of this crate, its when by under roll over and go up bottom this time can overlap each other.As previously mentioned, the order of rolling under the sidewall according to traditional crate must be observed, and could correctly fold this crate to obtain the remaining volume of a minimum folding crate.

Fig. 6 illustrates the cross sectional drawing of a crate, a middle position of what wherein this cross sectional drawing adopted is such as crate as shown in Figure 1.Crate 100 shown in Fig. 6 to comprise bottom this 102 and sidewall 108a and 108b.Bottom this, 102 comprise by 102 protrusion 102a and 102b protruded upward bottom this.These protrusions 102a and 102b is positioned at the outer edge of bottom this 102, and can with this bottom 102 formed one.This first protrusion 102a comprises one first hinge 150a, and this first hinge is shown schematically in Fig. 6.This first hinge 150a can provide the connection between this protrusion 102a and the first side wall 108a in such manner, and makes this sidewall can by rotate just like the direction shown in arrow 152a.From traditional crate, some device can be provided to allow that the movement of this sidewall 108a can only to be rolled over bottom this on 102 from a position, and upwards to one vertical position as shown in FIG. 6, and it is adjacent or at a upper surface place of this protrusion 102a that a lower surface 154a on this sidewall 100a can be arranged to.In a similar manner, one second hinge 150b is arranged in one second protrusion 102b, but as found out by Fig. 4, these hinges 150a and 150b is relative to 102 being arranged on different At The Heights bottom this.This hinge 150b is connected to this sidewall 100b with a pipe link 156, and can with the direction of arrow 152b towards 102 rotating bottom this.

Have the crate of structure as shown in Figure 6 according to one, it must carry out lower folding sidewall 108a and 108b with correct order, just can guarantee that this folding crate has a minimum volume.Fig. 7 illustrates that one of the crate shown in Fig. 6 is correct and an off-square is folding.According to the crate shown in Fig. 6, when will correctly be folded, must first lower folding sidewall 108b, and make it smoothly be adjacent to bottom this 102.Then this second wall 108a can by lower folding.When observing this correct order, the outside face of this sidewall 108a will leave in fact the identical At The Height of bottom this 102 at upper surface 158a with 158b as this protrusion 102a with 102b.These sidewalls 108a and 108b is arranged to make their lower surface 154a and 154b can be adjacent to the madial wall of these protrusions 102a and 102b.As found out by Fig. 7 (a), can form in accordance with this correct fold sequence the folding crate that has minimum volume.

But, when not being observed about the fold sequence described in Fig. 7 (a), can be reached just like the result shown in Fig. 7 (b).As found out, lower folding sidewall 108(a in the ban) time, will be arranged to only have its anterior or upper adjacent bottom this 102, and this second surface 108b can post in such manner on first surface 108a, make the outer wall at least partially of this second sidewall 108b can exceed the level of upper surface 158a and 158b of these protrusions 102a and 102b.

Therefore, these folding crates of storehouse to be impossible, stack because whole and will become unstable.Therefore, make these protrusions 102a and 102b have a height to one of this problem traditional solution, this highly make to have nothing to do in these sidewalls 108a and 108b fold sequence and the over water of these lower folding sidewalls is put down in fact corresponding to the height of the upper surface of protrusion 102a and 102b.Although this can solve the problem of the potentially unstable storehouse of folding crate, simultaneously, it can reduce can by the number of the folding crate of storehouse, because minimum volumes of these lower folding crates can increase.

According to the investigation of the present inventor, found that the increase of this minimum volume may make the total amount of the crate that can transport on an ordinary pallet reduce and may be up to 15%, and caused the shipment and delivery cost increased, this is less desirable.

Therefore, according to embodiments of the invention, the hinge arrangement of this crate can by with just like be described in more detail in after mode revise.Fig. 8 illustrates a cross sectional drawing being similar to Fig. 6, but, the hinge arrangement of this correction is shown.Again, 102 to be illustrated with protrusion 102a and 102b and sidewall 108a and 108b bottom this.In these protrusions 102a and 102b, these hinges 150a and 150b can be provided, but this each hinge is movably disposed within the groove in these protrusions 102a and 102b, and be connected to respective sidewall 108a and 108b with respective bar 160a, 160b.In the state shown in Fig. 8, these sidewalls are by upper folding and be in vertical position, and make their lower surface be adjacent to the upper surface of these protrusions.The position of this hinge 150b is same as in fact the position of the hinge in Fig. 6, but, the position of this hinge 150a be with hinge 150b phase same level place, and these two hinges are at varying level place in figure 6.

When crate as shown in Figure 8 will be folded, have nothing to do in it and whether first will roll under sidewall 108a and then roll under sidewall 108b, or carry out on the contrary.Fig. 9 illustrates that it sidewall 108b first can be rolled over or sidewall 108a first rolls over when the crate of Fig. 8 is by situation during lower folding.Can find out in Fig. 9 (a), this second sidewall 108b is first rolled over, and therefore it to be arranged to be adjacent to bottom this 102.In the case, this hinge 150b can be retained in as the position shown in Fig. 8 in fact, and a gap between the lower surface and the madial wall of this protrusion 102b of this sidewall 108b is decided by the length of this bar 160b.On the other hand, hinge 150a can move to a upwards position from the position shown in Fig. 8, and allow that this first side wall 108a posts on the second sidewall 108b, make the level of the outside face of this sidewall 108a correspond in fact the upper surface of these protrusions 102a and 102b.

Fig. 9 (b) illustrates a similar arrangement, but this first side wall 108a is rolled over by first lower, and a hinge 150a is retained in as the position in Fig. 8.As the explanation about Fig. 7 (a), in this example, the hinge 150b of this second sidewall 108b is allowed to move up, and therefore in this example, the outside face of this sidewall 108b is positioned at the level place that corresponds in fact a upper surface of protrusion 102a and 102b.By allowing that each hinge can be moved, then as the situation in Fig. 7 (b) can be avoided, as from Fig. 9 (b).Therefore, according to embodiments of the invention, do not need the height increasing these protrusions, and the arrangement of foundation embodiments of the invention, the upper level of these lower folding sidewalls is in fact always identical with the upper surface of these protrusions 102a with 102b, no matter and be that this first side wall 108a or the second sidewall 108b is by first lower folding.By avoiding the height of these protrusions to increase, therefore the overall number of the folding crate that simultaneously can be transported on a supporting plate can increase, and therefore the transport of these lower folding crates can than more efficient with traditional practice.

In Fig. 6 to 9, the cross sectional drawing of this crate is illustrated not containing end wall.But please note that these end walls also foldedly must could obtain the crate rolled over, and according to embodiment, these end walls are by first lower folding, and therefore these sidewalls can be adjacent to bottom this after by lower folding, but post at least in part on the end wall rolled in these lower.Also other embodiment can be had, only just can by lower folding after these sidewalls are by lower folding according to their these end walls, and in the case, the principle of embodiments of the invention, described in this second aspect relevant, content is also applicable.

The third aspect-" breech lock/latch release mechanism "

Below, the embodiment of the present invention according to the third aspect will be described.The bolt lock mechanism that traditional folding crate is not respective, it can provide a latch operations they to be fixed together at these end walls and sidewall when their vertical position.One example of this bolt lock mechanism is in the end wall of a collapsible crate, provide a pair moveable breech lock, and it is when this vertical position, can engage the corresponding breech lock bearer element be arranged in adjacent wall.Certainly, respectively other breech lock and breech lock bearer element also can otherwise provide, that is, these breech locks can be arranged in sidewall, and these breech lock bearer element can be arranged in end wall.

Figure 10 illustrates the first case of conventional latching mechanisms.In Figure 10 (a), this crate 100 illustrates this first side wall 106a with multiple vent openings 110.By end wall hinge 170a and 170b, end wall 106a to be rotatably installed in bottom this 102, and allows that this end wall 106a is when by can towards this lower rotation during lower folding.Further, these sidewalls 108a and 108b is also illustrated.In the part that this grasps above the 112a of hole, the top 172 of this sidewall 106a, shown with being reinforced, makes can guarantee enough rigidity and intensity when band gives during this crate, and this breaking of top grasped above the 112a of hole can be avoided.Further, two bolt lock mechanism 174a and 174b are arranged in this end wall.Figure 10 (b) illustrates an example of this bolt lock mechanism 174a with an enlarged drawing.In this instance, a breech lock 176 is installed in the groove 178 in this end wall 106a.This breech lock 176 can by a spring member 180 be also located in this groove 178 be biased in one outward to.In this sidewall 108a, there is a groove 182 to be established supply to accept this breech lock 176, realize the breech lock between this sidewall and end wall in this way.For discharging this bolt lock mechanism, one suitable actuation element can be arranged in this bolt lock mechanism 174a, this breech lock 176 of its tolerable moves inward, and namely enters the direction that leaves this sidewall 108a, and make this breech lock 176 and a breech lock be located in this groove 182 is accepted or to support element 184 release off.After a breech lock is released, this end wall can be folded down on bottom this, and then this sidewall also can by lower folding.

Figure 11 illustrates another example of traditional bolt lock mechanism.In Figure 11 (a), one is similar to the arrangement shown in Figure 10 (a) and is illustrated, only except this bolt lock mechanism is differently implemented.This bolt lock mechanism comprises a lifting arm 186, and this lifting arm can by (vertically vertically) moves, as shown in arrow 188 vertically.Figure 11 (b) illustrates that one according to the enlarged drawing of the bolt lock mechanism of this example.As found out, the outer end of this lifting arm 186 is provided with clasp 190 or a breech lock, and it is contained in this sidewall 108(a) groove 182 in, and engage this breech lock to support element 184.This lifting arm 186 by with one downward to bias voltage, therefore when these sidewalls and end wall are in this vertical position, this clasp is forced to be butted in this element 184, pins these sidewalls and end wall securely thus.When discharging these sidewalls and end wall, this lifting arm can upwards be improved, and this clasp and this element 184 are released off, and allows that this end wall 106a can be moved downward or rotate on bottom this.

Although approximately this bolt lock mechanism energy smooth operation, and each wall portion in a vertical state time one can be provided firmly to lock, its have a shortcoming to be these bolt lock mechanisms may be discharged when push-down stack by mutually at multiple crate.This can cause aforesaid problem.Such as, when by storehouse on a supporting plate time due to the vibrations of these crates or improper operation, then the bolt lock mechanism of these crates one or more may discharge, such as, because vibrations cause these latch components to move along its release direction.This may cause a kind of situation, wherein one or more stack one in crate have the wall do not locked, and the structure integrity making this entirety stack is on the verge of dangerous situation, because of these crates possibility avalanches one or more, so also will be dropped by storehouse other crate on its top.

For avoiding these situations, the embodiment of the present invention's foundation third aspect provides a kind of bolt lock mechanism of novelty, is described hereinafter with reference to Figure 12.Figure 12 illustrates the lockout mechanism according to one embodiment of the invention.Mechanism is in fig. 12 similar to the mechanism shown in Figure 11 (a), only except this lifting arm 186 is set as, when discharging this breech lock or locking, have at least a part of 186a and 186b to be moved, make its elevation-over of stretching out this crate or the upper limb higher than this crate.In this example, bolt lock mechanism as shown in figure 12 can be similar to the mechanism shown in Figure 11 (b), only except it is set as the upper limb being adjacent to this end wall 106a and sidewall 108a.Figure 12 (a) illustrates that this crate and this lifting arm 186 are in unlocked position, and as found out, these part 186a and 186b extend above the upper limb one of this crate apart from d.This allows the simple locking/release of these crates.But this bolt lock mechanism must be moved the height exceeding this crate and just can be released.This can be avoided the problem when the multiple crate of mutual upper push-down stack.

Figure 13 illustrates the lateral plan of crate with the novel bolt lock mechanism according to another embodiment of the present invention.Figure 13 (a) illustrates that this crate has this bolt lock mechanism and can stop that this sidewall shifts to this end wall, and Figure 13 (b) illustrates that this bolt lock mechanism is in this releasing position.More specifically, according to the embodiment of Figure 13, as in other embodiments, this crate comprise one bottom 102 and this end wall 106a.Please note that relative end wall 106b also has the structure identical with the end wall shown in Figure 13 (a).Further, these two sidewall 108a and 108b are also illustrated.At the corner parts of this crate, each sidewall 108a and 108b includes protrusion 190a and 190b, and the thickness of this protrusion corresponds to the thickness of this end wall 106a.These protrusions 190a and 190b can comprise multiple gap 192, and they are provided to hold the protrusion on the front being located at this sidewall 106a, in order to increase the connective stability between this sidewall and end wall.This lift system 186 formed by an arch-shaped elements, and it has end 186a and 186b, and this end flushes with a upper limb of this crate when latched position.This lift system 186 comprises two pin 194a and 194b, sells for these two and extends through with a vertical direction extension and slotted eye 196a and 196b be arranged in this end wall 106a towards the inside of this crate.Via these pin and slotted eye 194 and 196, this lift system 186 can be reached along one of a vertical direction limited movement, and along a horizontal side to undesirably mobile understand be avoided.In addition, this lift system comprises spring element 198a and 198b, and this spring element has one end to be connected to this mechanism 106, and the other end abut against this antetheca or sidewall 106a one on the lower surface of bar 199.These spring elements 198 abut against bar 199 on this, and need not be fixed in it, but in an embodiment, are connected also can be provided with one of bar on this 199.These elements 198 formed by the material identical with crate with this lifting arm, such as plastic material.The embodiment of change also can use other spring element formed by different materials (such as metal or analogue).This lifting arm 196 can be biased into the position as shown in Figure 13 (a) by these elements 198.

Figure 13 (b) illustrates that this lift system 186 is in its releasing position.As found out, the biasing force that this lifting arm 108 can resist these spring elements 190a and 190b moves to a position, this position than the latched position shown in Figure 13 (a) closer to bar on this 199.Move with this direction the skew that this mechanism 186 can cause these elements 198, make when discharging this lift system 186, it can be pushed rearward the position pushed back shown in Figure 13 (a).As found out by Figure 13 (b), the rising of this element 186 can make end 186a and 186b promote, and corresponding lock pin 187a and 187b of element 186a and 186b from the upper surface being located at these protrusions 192a and 192b is discharged, they are engaged by the respective openings in these elements 186a and 186b or groove, in order to this end wall and these sidewalls to be locked mutually.

In the position shown in Figure 13 (b), this lockout mechanism is released and this end wall of tolerable is folded down on bottom this, and then these sidewalls can be rolled over down bottom this.

As found out by Figure 13 (b), as about the embodiment described in Figure 12, also move to above the upper limb of this crate in this these element 186a and 186b, therefore when have other crate one or more by storehouse on the crate top shown in Figure 13 (b) time, this mechanism 186 can not activated and enter the position shown in Figure 13 (b).

Another advantage for the solution described in the embodiment of the present invention about this lockout mechanism is to provide the material of a costliness to form these elastic elements 198a and 198b, and according to these embodiments, same material in order to make this whole crate also can be used, such as, identical plastic material.Traditional method can be limited by an inferior position, and namely identical material is used to form this crate and these elastic elements, such as plastic material.At the life period of this crate, this spring member (its material is the material forming this crate) may lose all or part of its elastic nature.In in the case, will lose or reduce in order to the strength of this lift system of maintenance/bias voltage in position Figure 13 (a) Suo Shi.This can increase the danger of this breech lock of release, even if only have less power to put on this crate.Can be avoided according to these problems of embodiments of the invention, if because of this crate be set as one stack and the crate having other atop (if general fashion is that the crate filled can be transported), then this lifting arm is remained on this latched position not only can to reach by this biasing force led down of mat, and also could discharge this breech lock because this structure needs this lifting arm to stretch out higher than this upper limb.

Therefore, even if this elastic component may lose its elastic nature, but opening improperly of this mechanism can be avoided, because this lifting arm can not be moved into above the upper limb of this crate in this stacks, so opening of this lockout mechanism can not be allowed.

Figure 14 illustrates an example, wherein has two crates 100 and 100 ' to be gone up push-down stack mutually.As can be seen from Figure 14, due to storehouse, then the movement of the lifting arm 106 in this crate 100 will be no longer possible, because another crate 100 ' is disposed in above this crate 100.Therefore, crate 100 can not be unlocked, and above-mentioned problem can be avoided.

Although Figure 12-14 describes the embodiment that the present invention uses lifting arm, please note that the present invention is not limited to these embodiments.And other latch component or locking member also can be used, it allows breech lock and breech lock releasing off support part, and these respective element can be set as hypothesis when a unlocked position by structure, and the movement at least partially of this mechanism must be made to exceed this height.Such as, replace and use lifting arm, rotatable element can be arranged on the two ends of this end wall, it is one by the state rotated when this latched position, but when discharging this breech lock, then these elements must be extended over the upper limb of this crate at least partially by upwards rotating to make it, make to reach foregoing same effect during the multiple crate of push-down stack on mutually.Although Figure 12-14 describes this bolt lock mechanism or lockout mechanism is provided on end wall, but please note that the present invention is not limited to these embodiments, and this lifting arm or other movable latch component also can be arranged in these sidewalls, and these end walls can be provided respective breech lock to support part.
