Description

The hookup location

Technical field

The present invention relates to a kind of hookup (coupling device), be used to be connected at least one first corner component (comer fitting) on the freight container, described hookup comprises at least one first mate, wherein said first mate can be inserted in the described corner component at least partly, and be used to make it to be meshed with described corner component with a bearing state (holding condition), so that help described hookup is remained in the described corner component, and it can be broken away from from described corner component.

Further, the present invention also relates to fix use and a kind of method that is used for hookup is inserted into a corner component of container with a hookup.

Background technology

When shipping goods, for example on freighter, cargo-carrying train and automobile, the use of part load (goods), cargo hold and thermal container is very widely.Because the size and the strong design of standard can allow a series of adjacent freight containers to pile up mutually, therefore this freight container is easy to handle in the process of loading and unloading.Piling up in the storage that occurs in goods in the freight container too of freight container.This design of freight container is commonly referred to as the ISO freight container, and the goods that betransported is well protected in transportation and in the process of loading and unloading.

The freight container of the above-mentioned type is normally rectangular, has base plate, top board, two sidewalls and two end walls.End wall is made up of an opening portion usually, and this opening usually is made up of two fan doors, and wherein each fan in the two fan doors all is to be hinged on the opposite edges of above-mentioned end wall.Corner component is set at the corner of freight container usually, in order to the connection between the support set vanning and fixing.

In order to connect and to fix two or more freight containers, need to use a hookup, it can be inserted in the opening on the corner component that is arranged on an ISO freight container.Such hookup has a lockout mechanism usually, is used for hookup is locked in securely the corner component of freight container.

There are several hookups at present.First kind of hookup is so-called " full automaticity " hookup, and this is a kind ofly to be designed to insert in first corner component, can insert from second corner component of freight container thereafter and/or shifts out the hookup that does not need manual locking or unblank in this process.The different structure of " full automaticity " hookup exists, for example, when freight container is separated from each other, for " full automaticity " hookup is broken when connecting from least one of two freight containers that stack adjacent one another are, have to be rotated slightly at freight container, rotate, twisting or bevelled is local embodies.

Second kind of hookup is so-called " S. A. " hookup, and this is a kind of hookup that may not need manual locking in being inserted into the process of corner component.But " S. A. " hookup need be before it be moved out of corner component, and in the mate at least one manually unblanked.The handling device that is used for manually unblanking is the zone between two mates normally.In the use, therefore this zone, has produced the space between two freight containers normally between two freight containers that stack.

The lockable hookup of the sort of type above-mentioned for example can provide one or two lock portion that is designed to the screw cone of spring load, and it is suitable for being moved with rotation and is connected with the corner component locking of ISO freight container.Two screw cones are normally by a rotatable shaft phase-splitting bonded assembly that is placed in the housing.This hookup is commonly referred to as " reversing lock ", can be " full automaticity " or " S. A. ".Another kind of hookup above-mentioned is that in a kind of mate one or two all is the hookup of rotating element not.The shape of mate can be an outshot then, and for example a protruding nose (nose) or is linked up with (catch), and it can be fixed, and also can be movably.In use, outshot can enter corner component, with the inner abutment of the end wall of corner component.This hookup also can be " full automaticity " or " S. A. ".

In present transport systems, comprise the freighter that for example can hold thousands of freight containers, in order to use existing volume of compartment effectively, freight container all stacks up and down.In order to guarantee that this stowage is safe, each freight container all passes through for example above-mentioned lockable hookup in transportation, links to each other with the freight container or the transportation device of at least one adjacency.

For the ease of operation, the size of freight container is standard normally, and wherein a lot of sizes all are acceptables.Two kinds of sizes commonly used are 20 and 40 feet freight containers.Load two 20 inches freight containers 40 inches above the freight container or below also be possible.But, because limited space between freight container, when load two press close to each other 20 inches freight containers the time, hookup is inserted in the corner component of another freight container of adjacency and manual locking is difficult to, also danger close.If for example a porter is in order to be fixed on hookup in the corner component, and must put in arm between the freight container time, he or she may be sandwiched in two freight containers.This potential safety hazard does not occur over just when loading 20 inches freight containers.Because the weight of freight container and on the deck limited operational space for example on freighter the time, no matter how many sizes of freight container is, the danger of being correlated with all exists.

In order to obtain freight container safety and firm connection each other, will be very important in the hookup insertion corner component separately in the expection mode that has an expection location.

A common freight container is fixed by four hookups, one of each corner.Do not come the loading or unloading freight container when all having M/C at each mate, just during " full automaticity " hookup, it is vital correctly locating.Because when handling the place that freight container twists, tilts or rotates, hookup must be with the direction work of an expection.Concerning the design of some hookups, if one or more hookup by location of mistake, this is to being vital with container loading on another the time.Even further, if a freight container has the hookup of one or several location of mistake, and can overlay on another adjacent freight container, when attempting to unload them, it is impossible dividing defection to become in freight container, or bothers at least very much.And, the loading that promptly allows to finish freight container with separate, the hookup of location of mistake also may be damaged, or causes the damage of corner component or freight container in operating process, this can cause unsafe operation and increase expense.

For " S. A. " hookup, also there are the needs that require the correct location of hookup, because for instance, the porter must be able to enter in the executive component in order to unclamp at least one mate.If executive component is not the outside that is positioned at freight container, just be difficult to enter wherein, so the unloading of freight container will become pretty troublesome.

Patent US5 has proposed to attempt to solve orientation problem above-mentioned among 560,088 the embodiment, wherein joining part provides two lock flange.The shape of these lock flange is such, and they can stretch out in the vertical long hole by corner component.Therefore, when joining part only is in specific relevant position, just can be locked in the corner component.The major defect of this solution is that lock flange is stretched out by vertical long hole, is positioned at outside the exterior boundary of freight container.This can cause and the conflicting of other object, and for example is loaded in the freight container on next door or is positioned at the apparatus of loading area.If this conflict strengthens, cause to lock flange to apply application force that will produce the danger that hookup is forced to break away from the latched position of expection, the result is that hookup no longer keeps container fixing together.In addition, in order to insert hookup, an operator must make two lock flange enter corner component through the processing of complexity, and this is pretty troublesome and more time-consuming.

Another kind of selectable method attempts to solve the orientation problem of proposition in DE202004013463U1, and the connection outshot that wherein will be inserted into the hookup in the corner component has a plug screw.This plug screw has produced a kind of asymmetric, and this is used to produce a kind of influence, and promptly connecting outshot can only insert in the corner component with a kind of location.This solution makes the connection outshot just can enter corner component through the processing of complexity, and this is pretty troublesome to an operator, and is therefore more time-consuming.In addition, in this solution, when connecting outshot insertion corner component, can not determine that whether hookup is by correctly still location of mistake.This connection outshot also provides manual locking device, and the operator must operate in the insertion process that connects outshot.

Therefore, we need a kind of hookup, and it can insert in the described corner component with the location of expection.

Also there are the needs that the hookup that need not manual locking is provided in we.

In addition, we want to provide a hookup, and it can not produce conflict with other equipment in loading area.

We also want to provide a class to be easy to insert lockable hookup in the corner component as described above.

Summary of the invention

An object of the present invention is to provide a hookup, it is the problem of mentioning at above-mentioned, and is convenient to it is inserted in the corner component with location expection with an expection.Further purpose provides one and can not produce the hookup of conflicting with other device in the loading area.

A further object of the present invention provides a kind ofly inserts and is connected method in the corner component with hookup with the location of an expection.

Further purpose provides a hookup, when freight container stacks up and down, can optionally need not leave the space in the middle of them.

Further purpose is still and introduces a hookup, and it does not need can enter corner component through complicated processing.

At least a portion purpose above-mentioned is to reach according to hookup in the claim 1 and the method in the claim 25.Preferred embodiment embodies by dependent claims.

According to a first aspect of the invention, provide a hookup that can be connected with first corner component of freight container at least, described hookup comprises at least one first mate, wherein said first mate can insert in the described corner component at least in part, and be used for a bearing state and the engagement of described corner component, in order to help described hookup is bearing in the described corner component, and can from described corner component, break away from, wherein said first mate can move between at least two different states, one the first outstanding state (protruded condition) with respect to described hookup main body, with second an indentation state (retracted condition) with respect to described hookup main body, wherein said hookup also comprises sensor, whether it is to be provided for surveying described hookup to be inserted in the described corner component with a location of expecting, wherein said sensor is to be configured to detect a undesirable location when it, described sensor and one prevents the device mating reaction that the state of described first mate changes, like this, when a undesirable location was detected by described sensor, described mate was prevented from a bearing state and the engagement of described corner component.

The hookup that is provided with in said method has been realized the intended purposes to small part.Because sensor may detect any undesirable location, hookup inserted corner component with undesirable location and/or the risk that is arranged in the corner component with bearing state just has been lowered.

Preferably, described sensor can insert in the described corner component at least in part.

Wherein sensor can be inserted corner component to be arranged on the protection hookup aspect that can not be inserted into undesirable location be useful.In order to measure the location that has reached expection still is undesirable location, and sensor then can cooperate with corner component, and therefore, we can obtain safer detection.

In addition, because sensor can insert in the described corner component at least in part, the present invention means do not need sensor between freight container.Therefore, hookup can not produce the space between freight container, so stacking between the freight container can be tightr.

Preferably, the described first engaging piece branch that is in described outstanding state forms a border, it prevents to produce described hookup is in described bearing state in described corner component passage, and the described first engaging piece branch that wherein is in described indentation state allows to produce described hookup is in described bearing state in described corner component passage.

The mate of She Zhiing will help to realize purpose above-mentioned after this manner.According to an embodiment, if first mate is in its indentation state when inserting corner component, and sensor detects a undesirable location, and mate will be blocked its motion to an outstanding state.If connecting device does not arrive an outstanding state, hookup just can not arrive bearing state, therefore can not remain in the corner component.According to another embodiment, be in its outstanding state if become when hookup inserts corner component first mate, and sensor detects a undesirable location, mate will be blocked its motion to an indentation state.Because first mate will remain on its outstanding state, the outer rim of hookup (outline) can be such, so that hookup can not be inserted in the corner component.Because hookup will can not insert corner component, it also just can not keep the engagement of a bearing state and corner component.

Aptly, described sensor is set to prevent that described first mate is from the change of an outstanding state to an indentation state.

At this moment, first mate will can not be inserted in the corner component with a undesirable location.If hookup does not insert in the corner component when mal is located, can confirm more reliably like this, and be easier to operate hookup.Because hookup is not to insert completely, the operator will obtain a response immediately then, therefore no longer lose time wrong first insertion of whole hookup, and it is removed, and insert once more with different location then.The hookup of some previously knowns must be handled through intricately and enter corner component, must shift out corner component through the intricately processing again if insert mistake thereafter, compares with them, and the time saving effect of the present invention is fine.

According to an embodiment, described sensor is set to a location member (orientation memer), and wherein said align member can move between two states at least, i.e. an outstanding state and an indentation state with respect to described hookup main body.

Preferably, described align member is so arranged, and when the motion of described align member between described indentation state and described outstanding state was blocked, it can prevent the change of the described first mate state.

Preferably, when align member can not be moved into an outstanding state, therefore the detection of correct/error location set up by sensor.

Preferably, described align member and described first mate and adjacent part (abutmentportion) cooperating, when detecting the undesirable location of described hookup, adjacent part just is set to and they adjacency.

With first mate and the corresponding adjacent part of align member be the actv. mechanical solution that realizes expection about the block function of the motion of first mate.Except efficient, its structure is also uncomplicated, we can say, it has a reliable structure that problem may can not take place in mechanism.

If because adjacent part is in from an outstanding state to the mobile route of the expection of an indentation state, the adjacent part of align member will be blocked the motion of first mate, therefore can realize its function.So, be in when first mate under its outstanding fully state, do not need between adjacent part to be in contact with one another, as long as the adjacent part of align member is in this position, make that when detecting undesirable location, it can block the mobile route of first mate expection.

Aptly, when described align member was in described indentation state, described adjacent part will be set to be close to mutually.

Therefore, when each adjacent part is close to mutually, will obtain the blocking-up of the state variation of first mate.

Preferably, when described first mate is in its described outstanding state, described adjacent part will be set to be close to mutually or interlock.

By this set, first mate can not arrive the bearing state in corner component.Preferably, first mate can not become an indentation state from an outstanding state, and therefore, if when align member is in the indentation state, mate just can not be inserted in the corner component.

Preferably, when described hookup was expected the location in corner component, described hookup can be set to allow described align member to change state, promptly becomes described outstanding state from described indentation state.

If when being positioned at the location of expection, align member can change to outstanding state from the indentation state, and first mate promptly can be connected with corner component by a bearing state.But when if align member or sensor detect a undesirable location, align member will remain in its indentation state.Preferably, the adjacent part on first mate and align member will be close to mutually, and first mate then will be blocked it from the motion of an outstanding state to an indentation state, thereby realize the function of expection.

Preferably, when described hookup inserted in the described corner component with the location of an expection, described align member stretched out a side mouth of described corner component.

Because the design of most of common corner component, it may be preferred allowing align member to stretch out from the described side mouth of corner component.If align member stretches out this side mouth, it has been in its outstanding state, therefore allows first mate to change to a bearing state and corner component ingear state.And, at this moment being in the location of expection, the operator will obtain the clear signal that hookup is properly oriented.

Most of common corner component have three openings that are positioned on the adjacent wall usually, and above-mentioned sidewall to be configured to relative to each other be mutually perpendicular.All openings point to the outside of freight container.First opening is usually located at the lower surface or the upper surface of corner component, and this depends on that corner component is positioned at the lower surface or the upper surface of freight container.Other then opening lays respectively on the end wall and a sidewall of freight container.When with the freight container of upper and lower settings fixedly the time, respectively, the opening on the upper and lower becomes the engagement opening, and each opening on the sidewall becomes side mouth.The side mouth that align member can therefrom stretch out relies on the shape and the structure of hookup.But also may be that the freight container that is arranged side by side is fixed.Any one opening on container side wall or end wall all will become the engagement opening, and the opening that is positioned at corner component top or bottom will become side mouth, and align member can therefrom stretch out.

Preferably, when described hookup was arranged in described corner component, in order at least temporarily to empty near the entrance area side mouth of corner component, described align member was provided with movably.

When hookup is inserted in the corner component, may between the wall portion of hookup and corner component, there be a zone, just one in corner component in-to-in zone.When a hookup is arranged in corner component, can utilize the side mouth of corner component to insert in the corner component sometimes by devices such as for example swivel nut, bundle and similar components.Normally, hookup is in its bearing state in this case.Swivel nut, bundle and similar component can be after inserting side mouth, with the sidewall engagement of side mouth corner component on every side.Therefore, can all work with the mesh regional place that is used for swivel nut and bundle at entrance area in this zone.To insert device and enter this zone in order to allow, have the needs of removing this zone, so that at least in special time period, do not have the part of hookup to be positioned at herein.Therefore, corner component cavity place one restricted part can be thought in this zone.

Hookup is being inserted corner component, so that first mate reaches after the bearing state, align member can be in different positions with respect to entrance area.For example, align member can be arranged in entrance area at least in part.When for example attempting to insert a bundle or a swivel nut, we wish to remove align member in this case.For example we can finish moving of align member by align member being become the indentation state.Align member can at least temporarily be eliminated or remove then, thereby is producing a space or a zone that is used to insert a bundle or a swivel nut with the corner component adjacent.

In addition, sensor/align member can not be arranged in mesh regional, just should be eliminated in the zone.For example may be this situation,, when hookup is positioned at corner component with bearing state, not stretch out at least that it has not just been conflicted with the mesh regional that occurs if align member does not stretch out from hookup.

Another advantage of this embodiment of the present invention is, an if object, for example another freight container or machine contact with the align member of giving prominence to, align member will be just moves along the direction of its indentation state, and hookup is because this contact and contingent by dislocation or dangerously therefore can reducing of coming off from member parts.

If the described main body of described hookup also comprises a housing, described first mate and described sensor all are coated over the inside, and it may also have further advantage.

Preferably, described housing can insert in the described corner component at least in part, and wherein said housing constitutes guide piece, in order to described hookup is led in the into described corner component.

The partial action of housing is as guide piece, and this is very favorable because it can further help the operator when inserting hookup in the corner component with its correct location.

Preferably, at least when described first mate is blocked at described outstanding state by align member, the outside of the extended described housing of described first mate prevents that described hookup from inserting the outer rim of described corner component so that described hookup has one.

Aptly, described align member keeps described outstanding state with spring load.

Preferably, be accompanied by described freight container by the contact between parameatal surface of the engagement of described corner component and the described positioning element, the application force that is applied on the described align member can become described indentation state from described outstanding state with the state of described align member.

The structure hookup is so that it can be easy to the person of being operated operation, and this is a high efficiency mode, because operator's processing that need not add during insertion, align member just will reach its indentation state.In addition, by this layout, align member does not need just can enter corner component by the operator through the processing of complexity.

Aptly, described first mate keeps described outstanding state with spring load.

Preferably, described hookup is being inserted in the process of described corner component, be accompanied by described freight container by the contact between parameatal surface of the engagement of described corner component and described first mate, when detecting the location of an expection, the application force that is applied on described first mate can become described indentation state from described outstanding state with the state of described first mate.

In the insertion process of hookup, because the operator does not need to bear additional step, this also can increase the convenience of operation.In addition, by this layout, first mate does not need just can enter corner component by the operator through the processing of complexity.

So arrange first mate, so that its at least a portion can be between the outside of housing and inside moved by a groove, doing further advantage like this is can reach one to empty effect.When first mate passed through from groove, the dust or the dirt that contact and be attached on first mate can be wiped off by the sidewall of housing.The effect that allows first mate keep emptying is the running time that possible increase hookup.By in its outstanding state and the conversion between the indentation state, align member also will obtain same benefit.

Advantageously, described hookup further comprises one second mate, and it can insert in second corner component of second freight container at least in part.

Can recognize that the shape of second mate and structure are to take a lot of selectable design-calculateds.In any case its main purpose is can insert in the corner component of second freight container, so that together with two container fixing.

In a preferred embodiment, described second mate of described hookup that is arranged in second corner component of second freight container is to reverse lock, just reverses lock according to " S. A. " in the content described above or " full automaticity ".

No matter be " full automaticity ", still the lock that reverses of " S. A. " all is the hookup that can obtain added advantage in the hookup of describing from here.

Preferably, described first mate links to each other with described second mate, and the state of wherein said first mate can assign to handle by handling described second engaging piece.

Therefore by handling described second mate, the change of described first mate between outstanding and indentation state is possible.When attempting hookup shifted out from corner component, this operability is favourable.By handling second mate, therefore first link is become the indentation state from outstanding state, thereby to break away from from its bearing state be possible to first mate.When attempting to break away from first mate, from above-described type, determine the structure of hookup, thereby can no longer need extra operating control that this is an effectively mode.

Preferably, described first and described second mate be positioned on the complete relative end of a wheel shaft that extends between described first and second mates.This wheel shaft preferably has a length dimension that extends between first and second mates.The motion of first mate is preferably vertical substantially with respect to the rotation of wheel shaft.

In the process that described second mate is inserted and shifts out with respect to corner component, first mate can not shifted to its indentation state from its outstanding state.Therefore, second mate can only rotate in an angular range of being scheduled to, so that first mate can not be affected, just it can not be positioned at the indentation state, therefore can not become and shift out from its bearing state.

Advantageously, in described first corner component lower corner fittings that is the ISO-freight container.

Therefore, second mate preferably is used for being meshed with the upper corner fittings of second freight container.

According to the hookup in the preferred embodiment is preferably to be used to fixedly two ISO freight containers of arbitrary dimension.

According to a second aspect of the invention, a kind of method that hookup is provided in the corner component of freight container has been proposed, wherein said hookup comprises at least one first mate, it can move between two states with respect to the main body of described hookup at least, promptly first give prominence to the state and the second indentation state, and one and described first mate sensor that can be operatively connected, said method comprising the steps of:

-by an engagement opening of described corner component, will comprise that the part of the described hookup of described sensor is inserted in the described corner component;

-by described sensor, detect whether described hookup inserts in the described corner component with a undesirable location;

One remains on described outstanding state with described first mate, further inserts in the described corner component so that described first mate can prevent hookup.

It in corner component, provides a hookup in above-described mode, can realize part purpose of the present invention at least, because can cause hookup can not be positioned at the inside of corner component in any undesirable mode.

Before hookup was fully inserted into corner component, because the operator can receive hookup by the feedback of location of mistake, therefore the above-mentioned method that provides was an actv..This particularly compares with the hookup of some previously knowns just for the operator has reduced time and trouble, and they are before recognizing that hookup is by location of mistake, and the operator must just can make hookup insert in the corner component through complicated processing.In addition, do not insert in the corner component because hookup can not become, hookup is become in corner component suspend in midair insecurely, the danger that just is in a location of mistake and/or non-bearing state will be reduced.

The method of the hookup that provides aptly, further comprises following steps:

-when the location is in a undesirable mode, described hookup is shifted out from described engagement opening;

-reorientate described hookup;

-by an engagement opening of described corner component, will comprise that the part of the described hookup of described sensor is inserted in the described corner component;

-by described sensor, detect whether described hookup inserts in the described corner component with a location of wishing;

-described hookup is moved further in the into described corner component, so that described mate can contact with the part of the parameatal described freight container of described engagement that is positioned at described corner component;

-described hookup is moved further in the into described corner component, so that described mate applies application force with contacting to described first mate between the parameatal described surface of described engagement, with so that described first mate becomes described indentation state from described outstanding state;

-move described first mate to enter in the described corner component.

According to said method, the insertion of hookup can bring following result, and promptly hookup is inserted into the location of expection.In addition, the operator needn't just can insert first mate in the corner component through the processing of complexity, because by the contact between the freight container and first mate, the first engaging piece branch is in its indentation state.

Aptly, described first mate is that spring load is to described outstanding state, wherein when described first mate is moved into the part that surpasses the parameatal described freight container of described engagement that is positioned at described corner component, described first mate will be biased into described outstanding state, therefore helps described hookup is bearing in the described corner component.

Like this, do not need the operator to operate any catch gear, hookup can become the bearing state that is in it.Therefore can eliminate the danger that the operator forgets locking or changes the bearing state of hookup.

Preferably, described sensor comprises certain position member, and the step of wherein inserting described align member comprises that when it was inserted in the described corner component with a location of expecting, described align member can stretch out from a side mouth of described corner component.

Because the most whether the design of common corner component about how sensor/align member is set is properly oriented to detect hookup, this is an effective and efficient manner.In addition, it can provide one about being easily understood and visual indication that hookup is correctly inserted.

If it can be very favorable that described method further comprises a step, that is, described align member is at least temporarily removed to empty described entrance area near the entrance area the side mouth of described corner component.

Other device in order to ensure for example bundle and swivel nut etc. inserts in the side mouth of corner component, and the method that hookup is inserted in the corner component comprises that also it is favourable that across corner accessory in-to-in inlet or mesh regional carry out temporary transient at least emptying.

The shape of housing 4 can be different.In a side of housing 4, preferably the relative side of that side that is run through when its outstanding state with first mate 2 is provided with an antelabium 20.Shown in Fig. 1-2 e, antelabium 20 can extend along a side of housing 4.Antelabium 20 is to be used for centering on together the bottom phase interlock of the corner component 6 that meshes opening 8, thereby helps hookup 1 is bearing in the corner component 6.

When two container fixing together the time, will be utilized four hookups 1 usually, respectively there is one in each corner of freight container 7,12.Can know from following description and to find out,, just two freight containers 7,12 can be coupled together that also for it being separated from freight container 7,12, hookup 1 accurately location is vital in order to play predictive role.

At the operation that two freight containers 7,12 are fixed together, hookup 1 is described in more detail now.Hookup 1 has been shown in Fig. 2 a, and wherein mate 2,5 does not all insert in the corner component 6,11 of an ISO freight container 7,12.But hookup 1 has been in a suitable position, and promptly the upper part of housing 4 is inserted in the corner component 6, and will reach the marginal portion 21 contacted degree of align member 3 and corner component.Although hookup 1 still is in a state that does not touch, first mate 2 and align member 3 all are in outstanding state separately.At this state, the adjacent part 15 of align member 3 does not mesh with recess 14, or is adjacent, so that block the mobile route of first mate 2.

The size of housing 4 is suitable for the engagement opening 8 of corner component 6.So, housing 4 has constituted the guide of slotted hole 8.Therefore housing 4 can only be inserted in the corner component with the two location of selecting one, and one is the location of expection, and one is undesirable with overturn 180 ° location of housing 4.But not under the shake-up state, the align member 3 and first mate 2 all protrude in outside the housing 4 in the present embodiment, so produced the outer rim of the hookup 1 of the engagement opening 8 that is not suitable for corner component 6 at hookup 1.Therefore, for hookup 1 being inserted in the corner component 6, by engagement opening 8 time, the both must be in indentation state separately at least for first mate 2 and align member 3.

Shown in Fig. 2 a, align member 3 has a upper surface in slight downward slope on away from the direction of housing 4.When hookup 1 further was inserted in the corner component 6, shown in Fig. 2 b, freight container 7 applied an application force with the meeting that contacts between the align member 3 to align member.Because contacting between the marginal portion 21 of align member 3 bevelled upper surfaces and corner component, when hookup 1 moves up when entering corner component 6, align member 3 can be pressed in the housing 4 of hookup 1.The application force that is applied on the align member 3 must be enough big, is enough to overcome the elastic force on the outstanding state that is biased in align member 3.

Along with align member 3 is pressed in the housing 4, adjacent part 14,15 now is positioned at a kind of like this mode, so that first mate 2 can be avoided moving to its indentation state.

Hookup 1 has been shown in Fig. 2 c further to be inserted in the corner component 6.Align member 3 has passed through the marginal portion 21 of corner component 6 this moment, and is positioned at the inside of corner component 6.Spring 19 forces align member 3 outwards to move with respect to housing 4 as can be seen, but it can only move as much as possible because the further motion that the sidewall of corner component 6 23 can blocking-up align members 3.In this position, the adjacent part 15 of align member 3 is still blocked first mate 2 from outstanding state moving to the indentation state.Therefore, first mate 2 is still kept its outstanding state.

Hookup 1 even further be inserted in the corner component 6 in Fig. 2 d (comprising 2d (I) and 2d (II)), and first mate 2 contacts with marginal portion 21 around the engagement opening 8 of corner component 6.The location of the expection of hookup 1 has been shown, and Fig. 2 d (II) shows undesirable location in Fig. 2 d (I), just from the expection position rotating 180 ° location.Even hookup 1 has illustrated its correct positioning by Fig. 2 a-2c, but for purpose clearly, we also will be to these two kinds of positions, and promptly correct is described with the off-square location.

The location of expection has been described in Fig. 2 d (I).When hookup 1 continues to insert corner component 6, align member 3 will be positioned at before the side mouth 9 of corner component 6.Because spring 19 can make it to an outstanding state to align member 3 biasings, so when not having sidewall to block its motion, align member 3 will be biased to its outstanding completely state.Can find out from Fig. 2 d (I) that align member 3 may be in a such position, promptly it stretches out side mouth 9 at least in part.Braking element 22 in the housing 4 can stop the outside motion of align member 3, so that align member can not dropped out from housing 4.Can find out that from Fig. 2 d (I) align member also has an inclined surface on its lower sides.This inclined surface helps align member is brought into or is with to side mouth 9.

When align member 3 was in its outstanding state, adjacent part 15 had left the recess 14 of first mate 2.Therefore, no longer block of the motion of first mate 2 to its indentation state.

As mentioned above, when align member 3 is in outstanding state, and to first mate 2 apply one sizable, be enough to overcome and can force first mate 2 outwards during the application force of the elastic force of the springs 18 of motion, first mate 2 can optionally move to an indentation state.Similar when inserting corner component 6 with align member 3, provide an application force by contacting between the surface 21, marginal portion around the first engagement opening 9 and first mate 2.With align member 3 also be similarly, first mate 2 has one along being directed downwards the bevelled upper surface away from housing 4.When inclined surface contacts with container surface around the engagement opening 9, and hookup 1 handled and entered in the corner component, and during for example by an operator, first mate 2 will be forced in the housing 4 of hookup 1.When first mate 2 had been pressed into or has pressed to housing 4, hookup 1 has one can run through the outer rim that meshes opening 9.

Situation when Fig. 2 d (II) shows hookup 1 location of mistake.With regard to the location, whether no matter carried out wrong or correct positioning, hookup 1 all will work in the same way.Now, because the corner component of a common ISO freight container has only two side mouth 9 that are positioned on the adjacent wall, so the position of side mouth is perpendicular to one another, and when in location of mistake, align member 3 does not have the side mouth that can allow it stretch out.When this location of mistake, align member 3 therefore will be in Fig. 2 c in identical position, so it will be blocked by the sidewall 25 of corner component 6.Can detect the undesirable location of hookup 1 by sensor/align member 3.Correspondingly, adjacent part 15 will be blocked first mate 2 from the motion of its outstanding state to an indentation state.

Since first mate 2 can not reach the indentation state, and according to the shape of housing 4, under this location hookup 1 guiding to be entered corner component 6 be impossible or be difficult at least.

The bearing state of hookup 1 in corner component 6 has been shown in Fig. 2 e.First mate 2 has passed through the lower surface of corner component 6, because do not have pressure to act on first mate 2 in this position, it is biased in outstanding state by spring 18, and this helps hookup 1 is bearing in the corner component 6.

Since first mate has been positioned at its bearing state now, the position of align member 3 will no longer influence the effect of first mate 2.For example for swivel nut, bundle or similar component are fixed in the side mouth 9 of corner component, and apply application force and bearing state that it is changed into the indentation state and do not influence first mate 2 from outstanding state is possible to align member 3.Be an indentation state by the state that changes align member 3, just may in side mouth 9, produce the space to fix a bundle, swivel nut or similar component.

The antelabium 20 of housing 4 preferably leans against on the bottom of corner component 6, thereby helps hookup 1 is bearing in the corner component 6.Because the design of antelabium 20, housing 4 may not can directly be inserted in the corner component 6.The operator who inserts hookup 1 may have to housing 4 is tilted a little, so that allow antelabium 20 by engagement opening 8.When antelabium 20 had been arranged in corner component 6, the operator can make hookup 1 lean on backward to a vertical substantially location, the wherein inner edge portion phase-splitting interlock around the engagement opening 8 of antelabium 20 and corner component 6.

In case when first mate 2 of hookup 1 had reached bearing state in corner component 6, second mate 5 can be fixed in second corner component 11 of second freight container 12, shown in Fig. 2 e.Fixing being present in usually under this situation between the freight container, promptly first mate 2 of four hookups 1 is fixed in each lower corner fittings 6 of first freight container 7.Thereafter by a for example hoisting crane, this freight container 7 is lowered with moving downward of an appointment with respect to second freight container 12.

In the embodiment shown in Fig. 1 to 2e, second mate 5 is one so-called " full-automatic twisted twist lock (fully automatic twis-tlock) ", and wherein second mate 5 all is being rotated hookup 1 from corner component 11 interlocks of second freight container 7 and the process of unclamping.Second mate 5 when released to compare opposite direction rotation when being inserted into corner component 11.For second mate 5 that makes four hookups 1 is inserted in the corner component 11 of second freight container, all hookups 1 must be properly oriented, because the work of must working in coordination that rotatablely moves of each second mate 5.Otherwise rotatablely moving that insertion process needs can not occur in all four hookups 1.In any case, hookup 1 should so design, to such an extent as to second mate 5, and the wheel shaft 13 that can influence first mate 2 can rotate fully so that second mate 5 with corner component 11 interlocks with unclamp, and does not force first mate 2 to leave its bearing state.

Be accompanied by mate 2,5 and all be fixed in separately the corner component 6,11, first and second freight containers 7,12 are fixed together now.

When unclamping freight container 7,12, second mate 5 will be to compare opposite direction rotation when being inserted into.But this rotation will can not force first mate 2 to leave its bearing state.

When freight container 7,12 is separated,, also be vital with hookup 1 correct location for second mate 5 can be worked in coordination with rotation.Otherwise rotatablely moving of second mate, 5 different directions will hinder the separation of first and second freight containers 7,12.

When freight container 7,12 was separated from one another, first mate 2 will still be arranged in first corner component 6 with bearing state.As mentioned above, first and second mates 2,5 can be set at or be positioned at wheel shaft 13 fully oppositely end near.For with hookup 1 from corner component 6 separately, mate 2 have to from the bearing state of corner component break away from, so mate 2 must be changed into the indentation state from outstanding state.According to an embodiment, rotate or rotate second mate 5 and can realize this variation.As shown in Figure 1, should provide on the wheel shaft 13 on a convex shoulder 27, the first mates recess 26 should be provided.When second mate 5 being rotated to an abundant degree, convex shoulder 27 by being further rotated of second mate 5, forces first mate 2 to reach its indentation state interlock recess 26.

When first mate 2 had entered the indentation state, it was possible that hookup 1 is fallen from corner component 6 at least in part.When hookup 1 has been fallen certain distance, align member 3 will lean against on the end portion of corner component 6.Yet as mentioned above, align member 3 has an inclined surface on its lower surface.This inclined surface is similar to the inclined surface effect that is positioned at align member 3 tops.Therefore, when for example a porter takes away hookup 1 from corner component, inclined surface will lean against on the end portion of corner component, if and the application force that is applied on the align member 3 surpasses when making its outside elastic force when being biased in align member 3, inclined surface will make align member 3 arrive housings 4.When indentation state when motion of align member 3, can allow hookup 1 by engagement opening 8 to it.To similar when housing 4 is inserted corner component 6, an operator may have to housing 4 is tilted, so that guide lip 20 is away from corner component 6.

Fig. 3 shows the present invention's one alternate embodiments.First mate 2, align member 3, housing 4, spring 18,19, adjacent part 14,15, wheel shaft 13 and spring 10 about layout with use all with the foregoing description in identical.But second mate 5 is one " S. A. reverses lock (semi automatic twist-lock) " in the present embodiment." S. A. reverses lock " can be connected in the corner component 11 under the situation that does not need manual-lock.Yet it need carry out manual unlocking by release gear 24.When freight container 7,12 was fixed together, release gear 24 was usually located between first and second freight containers 7,12.Concerning present embodiment, it equally also is very important that hookup 1 is arranged in corner component 6,11 with correct positioning.We wish that release gear 24 is positioned at the position of leaving 7,12 1 in freight container, because an operator must be near release gear 24 so that unclamp second mate 5 from corner component 11.If release gear 24 is so positioned, so that they are positioned at the position that two freight containers 7,12 stack each other, the operator may be difficult near release gear 24, so the trouble that becomes more of the branch defection between freight container.

Fig. 4 still shows another embodiment of the present invention, and wherein second mate 5 is one not rotate mate.Not rotating mate may for example be a protruding nose of fixing or the hook of a spring load.This does not rotate mate and can play a part identical with " full automaticity " or " S. A. reverses lock ".Typically, fixing protruding nose can play same function with " full-automatic twisted twist lock ", and the hook of spring load can play same function with " S. A. reverses lock ".First mate 2 in this example, align member 3, spring 18,19, adjacent part 14,15 and housing 4 are also all identical with the content described in the foregoing description.When second mate 5 in the present embodiment is inserted in the process of corner component 11, do not rotate motion.Second mate 5, if it is set to a fixing protruding nose, just identical with " full-automatic twisted twist lock " effect that comprises non-manual unlocking, it enters or shifts out corner component 11 by the relative motion of appointment between the freight container 7,12 so.The shape of protruding nose can be such, and when casing with convenient fixed set, top freight container 7 is placed on the following freight container 12 with bevelled motion.Further, protruding nose is like this by device, if so that freight container is tilted in relation to each other, if ship is because sea wind and wave and when at sea rocking for instance, hookup 1 will can be not released from corner component.For freight container 7,12 is separated, they must be lifted, and four all turnings are for example raised simultaneously with parallel and moved simultaneously along predetermined path.This predetermined motion is known to those skilled in the art, does not need further elaboration at this.

Fig. 5 has schematically described another embodiment.First mate 2 and housing 4 are not illustrated, but have and identical structure and the effect of content described in the embodiment of Fig. 1-2 e.Yet in the embodiment show in figure 5, align member 3 is biased to an indentation state. Adjacent part 14,15 also with the different mode of the embodiment shown in Fig. 1-2 e by device.Can be as seen from Figure 5, the adjacent part 14 of first mate 2 is configured to angled side, and the adjacent part 15 of it and align member 3 is adjacent.In addition, can know from following description and to find out that no matter which kind of state first mate 2 and align member 3 are in, adjacent part 14,15 all will adjoin each other.

When the state of first mate 2 was changed into indentation from giving prominence to, the adjacent part 15 of align member 3 slided along adjacent part 14 angled surfaces.Therefore, when first mate 2 when housing 4 moves, align member 3 will be extruded from housing 4.

In the use, under unaffected state, align member 3 can outwards not stretch from the circumference of housing 4, therefore in that hookup 1 is inserted in the process of corner component 6, does not need align member 3 is pressed into housing 4.But, be pressed into or press to housing 4 in order to make first mate 2, in order to obtain the passage that hookup 1 inserts corner component 6, align member 3 must be so positioned, so that it can utilize first mate 2 and be forced out housing 4 with a sufficient degree.In order not block the motion of first mate 2, the distance that align member 3 must be able to stretch out housing 4 is such, and promptly it only need reach the condition of side mouth 9 of align member 3 extended corner component 6 of allowing.Therefore, if the direction of hookup 1 is determined mistake, it can not make the distance that align member 3 stretches out to be needed, and therefore first mate 2 will be blocked it from outstanding motion to the indentation state.If first mate 2 can not arrive its indentation state, and is consistent with previous embodiment, just mate 2 can not be inserted in the corner component 6.At this embodiment, be pushed to place in order to prevent align member 3 away from housing 4, a stops 22 also is provided.

Hookup among this embodiment can be one " full-automatic twisted twist lock ", but it may to be one " S. A. reverses lock " or do not rotate mate yet.

Though the present invention describes in conjunction with its some specific embodiments, should be understood that under the situation that does not deviate from spirit and scope of the invention, those skilled in the art can make various distortion, change and modification.

Sensor 3 is described to a mechanical positioning member in embodiment with reference to the accompanying drawings.But sensor also can be set to detector for example electronics or optics.

The fixation procedure of freight container when embodiment has with reference to the accompanying drawings shown between the freight container of self direction setting fixedly.On the other hand, it is possible using creative hookup to fix the freight container that is arranged side by side each other.In the case, the engagement opening that is used to insert hookup will become an opening that is positioned on the corner component sidewall.Thereby, should " side mouth " promptly be equivalent to the opening on the corner component bottom in the above-mentioned example.

Some corner component have different distances between the center of corner component and sidewall, this is possible.In this case, when being positioned at correct location, just do not need align member 3 is stretched out the side mouth 9 of corner component 6.

First mate 2 is illustrated by the use of second mate 5 from the process that bearing state discharges.Yet it is possible that a separation device that first mate 2 is changed into the indentation state from outstanding state is set.

Providing an antelabium 20 on the housing 4, also is possible but be to use some other the engagement means that help housing 4 is bearing in the corner component 6.One alternative is to use the dual mate similar to first mate 2, stretches out from a wherein side of housing 4.

The structure of hookup is that align member is set to relative to each other vertical substantially state with first mate among the embodiment with reference to the accompanying drawings.But, because the design of most of common corner component, promptly have two side mouth that are arranged on adjacent wall portion, just have two and be configured to vertical side mouth fully, therefore first mate and align member are arranged on two relative sidewalls of housing, and still playing the function of wanting, this also is possible.

Shown the hookup 1 of the housing that has a type above.But this is not a kind of necessary design, and housing also can be taked other alternative shape.Even can not need housing, because first mate 2 can be provided with in identical but relevant with the main body of hookup mode with align member 3.If there is not housing, first mate and align member can form their outstanding and indentation states separately with respect to main body, and do not need to be arranged at least in part a housing.
