Description

Freight container with the door opening height that increases

The present invention relates to a kind of freight container, relate more specifically to a kind of cargo-type container, it has the door opening height that increases, cantilever thickness reduces to some extent on the doorframe, but do not change the outside dimension of rear frame, there is downward gradient on the floor to the doorway direction, thereby increases door opening height, so effective volume and efficiency of loading that freight container can be freighted increase to some extent.

Freight container in order to shipment for land, sea or air transport, being extensive use of on boats and ships, aircraft, truck or train, what require that their make can bear mal-condition in the transportation, and needs to adapt to the international standard size, so that they can be consistent with described transportation means series.Freight container doorway size is the factor of particular importance that influences the efficient of its handling goods.

The freight container of prior art, described in the 5th edition international standard ISO668 of issue on December 15 nineteen ninety-five, have some following shortcomings, thereby be necessary to be improved.

Prior art is introduced in detail with reference to Fig. 1, and it is the transparent view of a conventional freight container.Fig. 2 is the transparent view from the freight container of another angle displayed map 1.Conventional freight container 1 is hexahedron structure, and its front end frame 20 and back-end box 30 are contained in above the bottom construction 10, and are connected with top frame 40 and lower frame 50, and many blocks of plates are arranged on the oblong skeleton of top and side to form top cover 3 and side wall 5 respectively.

Fig. 3 is the decomposition diagram that shows conventional freight container back-end box structure.Fig. 4 is conventional freight container back elevational view, and Fig. 5 then is the scheme drawing that shows the side-looking section of conventional container bottom structure.

The back-end box 30 of conventional freight container 1 comprises a threshold 32, and it is equipped with corner post as the threshold of back on the bottom construction 10 at the two ends of threshold 32.Doorframe is housed at the top of corner post 34 puts the beams in place 36.At corner post 34 and doorframe upper beam 36 and threshold 32 connections case corner fittings 38 is housed.Hinge 65 is connected every fan door 60 respectively with corner post 34, so given end door 60 can forward fixing angle on hinge when 60 open.

As shown in Figure 5, bottom construction 10 comprises many floors support 12, and they are across the width of freight container, and floor 14 also links to each other with threshold 32, and keeps sustained heights with threshold 32.

As above in the freight container 1 of Gou Chenging, above threshold 32, be that door opening height is to be subjected to the put the beams in place influence of 36 thickness of threshold 32 and doorframe to the put the beams in place distance of 36 bottoms of doorframe, if the thickness that threshold 32 and doorframe are put the beams in place 36 increases respectively to some extent, then the doorway aperture will reduce same degree with described increase.

The thickness of top cover 3 puts the beams in place 36 for thin than doorframe on the other hand, and therefore the upper surface from floor 14 is higher than door opening height to the internal height the lower surface of top cover 3.Even therefore the height of the goods of pallet dress can adapt to internal container, but can not pack into by the doorway, because the height on doorway is relatively low.Therefore the pallet cargo that packs into the container is limited by door opening height, waste container top space.

An object of the present invention is to provide a kind of freight container with door opening height of increase, the thickness that its doorframe is put the beams in place reduces to some extent, and the oriented descending slope in the floor of bottom construction is towards the doorway, thereby the efficient of pallet loading pallet cargo and effective volume are all increased to some extent, and outside dimension and structural integrity remain unchanged.

For realizing described target, the present invention is constructed as follows:

Freight container back-end box of the present invention comprises a threshold that is contained in the container bottom structure rear side, be contained in the threshold two ends and stretch to the top corner post, a doorframe is put the beams in place and is contained in the upper end of corner post, across the back-end box width, and the case corner fittings is contained in the place that corner post is connected with threshold and doorframe upper beam, and the Men Zeyong hinge is contained on the corner post.This outer reinforcement then is contained in back-end box corner post and doorframe and puts the beams in place and be connected on the local interior angle.

The bottom construction of freight container comprises the floor, and it supports with threshold and a series of floor and is connected.The floor supports cloth is located at underfloor, and its arrangement is that distance between the adjacent supports is along with their distances to the doorway reduce and shorten.The height that its corresponding floor is supported also correspondence reduces, so that the floor that they are settled above becomes downward ramped shaped to the doorway direction.

Put the beams in place for the big door exterior surface of closed end and threshold, corner post, doorframe in addition, seal liner is equipped with in the slit that forms between the inside faces such as reinforcement on the door limit, and cause on the side of each case corner fittings chamfering with avoid and the door sealing liner between interference.

DETAILED DESCRIPTION OF THE PREFERRED:

The preferred embodiments of the present invention are illustrated referring now to accompanying drawing

Fig. 6 is a decomposition diagram, the structure of the back-end box of expression freight container of the present invention, and it has the doorway of increasing.Fig. 7 then is the sidepiece generalized section, the bottom construction of expression freight container of the present invention.

Threshold 32 is contained in the rear portion of

bottom construction

10, and 34 of corner posts are contained in threshold 32 both sides and stretch to the top, and doorframe is put the beams in place 36 and is in the upper end of corner post 34 across container width, and 38 of case corner fittings are positioned at put the beams in place 36 junction of corner post 34 and threshold 32 and doorframe.

As characteristics of the present invention, the thickness of doorframe upper beam 36 reduces to some extent, and the floor 14 on the bottom construction 10, then to the oriented descending slope of doorway direction, therefore door opening height (measuring to the lower plane of doorframe upper beam 36 from the last plane of threshold 32) will increase to some extent, and the outside dimension of freight container 1 does not change.

The thickness that doorframe is put the beams in place reduces to some extent, thereby door opening height increases to some extent, and its recruitment is doorframe the poor of cantilever thickness on 36 thickness and the conventional doorframe of putting the beams in place among the present invention.The layout of freight container bottom be contained in floor 14 above the bottom construction 10 about half distance that enters freight container to the oriented descending slope of doorway direction, thereby the increase of door opening height is identical to the threshold slippage with the floor.Floor 14 is to support 12 by the floors of many horizontal installations that are positioned at underfloor to be supported, these layouts that support 12 are to make any two adjacent floors support the height that distance between 12 and arbitrary floor supports all to reduce with them and the approaching of threshold 32.The height of floor support 12 reduces with the gradient on floor 14, and its layout is make the floor support following in the same plane.The abated effect of the minimizing of distance between 12 in order to the structural integrity of the thin 12 pairs of freight containers 1 of floor support of compensate for slower supported on adjacent floor.

Fig. 8 is the rear side that a front elevation shows freight container of the present invention.Fig. 9 then is the enlarged drawing at A position among Fig. 8.

In order further to strengthen weakening owing to the thin doorframe upper beam of touching upon previously causes freight container 1 structure of leading, reinforcement 100 is configured in corner post 34 and doorframe upper beam junction.The rectangular triangle of the shape of each reinforcement 100 also is contained in corner post 34 and doorframe and puts the beams in place on 36 angles that form, thus form the right angle reinforcement 100 two limits respectively with doorframe put the beams in place 36 and corner post 34 join.

Reinforcement 100 does not produce restriction to door opening height, but the angle is affected according to the size of reinforcement 100 on the end door 60.Thereby the hypotenuse shape manufacturing of reinforcement 100 is pressed at the last angle of end door 60.

For the outside face of sealed end door 60 and threshold 32, door pillar 34, doorframe put the beams in place 36 and each face of reinforcing member 100 between the slit that forms, on the limit of end door 60, seal liner 70 is housed.In addition, interfere when holding door 60 switches for fear of door sealing liner 70 and case corner fittings 38, make a chamfering 38a at the interior angle place of each case corner fittings 38, the shape of chamfering 38a is that its line of cut is parallel with the hypotenuse of reinforcement 100.

As mentioned above, structure of the present invention is that doorframe 36 thickness of putting the beams in place decrease, and there is the gradient on the floor on chassis 10 14 to the doorway, thereby the internal height of back-end box 30 can increase the freight container outside dimension and then remains unchanged.

On the other hand, because the thickness because of doorframe upper beam 36 of the intensity of top and the bottom, doorway reduces proportional decline, therefore must strengthen, just to satisfy the strength test of ISO1496 to the intensity that weakens.ISO1496 proposes the international standard that many freight containers should satisfy.

Have in the freight container that increases door opening height at such one, the difference of its internal height and door opening height is less than conventional freight container, and therefore the design of the pallet of shipment loading thing becomes and is easy to, and more goods can pack into the container in 1.

As mentioned above, the structure of freight container of the present invention is that the thickness that doorframe is put the beams in place reduces to some extent, and the freight container outside dimension is kept.The floor of bottom construction is to the oriented descending slope in doorway, thereby the increase of the internal height on doorway, thereby has increased freight container effective volume and efficiency of loading thereof.
