Description

Twistlock

The purpose of the present invention is a kind of twistlock, and it is used for two container combinations for stacking on the other side one Rise or for by container combination to fixing point in its lower section, the twistlock include main body, for container upper pivoting latch part with And the lower pivoting latch part of the counterpart for lower container or for erecting bed, the upper and lower locking piece is for example by means of axle rigidity Be connected to each other, and operation lines be arranged into the twistlock for rotate locking piece.

The present invention thus relates to be intended for staying in the coiling machine of the twistlock that the container transported on freighter is locked together The operation of structure.Certainly the container of bottommost is also locked to its erecting bed for example on the top of hatch board using twistlock. Although preventing the movement of the operation lines for being fixed to locking piece on the direction of rotation for discussing, spring mechanism allows twistlock Locking piece (swivel bolt) rotation in one direction.

Can be wherein manual, semi or fully automatic on its basic function using twistlock of the invention.

The intention usage of operation lines is the lock-out state for changing twistlock, for example, twistlock is arranged into release position, and is entered One step separates container with corner casting.If between operation lines and locking piece do not exist flexibility, then for example due to by , there is the danger of the rupture of operation lines in impact and the rotation due to locking piece in the wrong direction that container causes.

It is known in the art German Utility Model and discloses DE202012101261U1.Below, we more specifically join According to disclosed Fig. 6 and Fig. 9 for discussing.Additionally, label means the label used in Germany is open herein.In figure 6, on peace Sliding part (47) in the main body (25) of twistlock prevents the movement of operation lines (39) (as shown in accompanying drawing, in locking piece (37) when rotating counterclockwise).Be maintained at sliding part (47) in its external position by spring (50), because the spring force of spring (50) The spring force of the spring (42) than acting in backward direction is bigger.

Turn counterclockwise as the result (for example, when being locked between the two containers in twistlock) of external force in locking piece (37) When dynamic, sliding part (47) is drawn in its interior location while spring (50) is pressed by the operation lines (39) for being fixed to locking piece (37) Contracting.When the effect of the external force on locking piece (37) terminates, sliding part (47) is returned to its external position by spring (50), While locking piece (37) is drawn in its initial position by operation lines (39).

The shortcoming of the spring mechanism of the twistlock described above is, slide construction takes up room and increases the main body of twistlock Length.Additionally, sliding part is single " extra " part.It is also possible to sliding part obstruction or damages, in this case, turns round The operation multilated of lock.

It is an object of the present invention to realize not adding a kind of creative twistlock of aforementioned shortcoming.According to the present invention Spring mechanism be characterised by, in their longitudinal direction at least one flexible element spiral to operation lines, to be to operate Line with interface that is flexible or being slidably connected on the axle of locking piece, and be interface by flexible member each other or The half part of one flexible member is separated from one another.

Twist lock feature according to a preferred embodiment of the present invention is the presence of two flexible members, and one in connection On the both sides of point.

Twist lock feature according to the second, preferred embodiment of the present invention is, flexible member be on the top of operation lines from By the spiral spring for sliding.

The another preferred embodiment of twistlock of the invention is characterised by that flexible member is rubber components or other elasticity Part.

The one of the advantages of the present invention that can be mentioned is that construction very simple, operation are reliable and cheap.Additionally, of the invention Offer makes simpler, the smaller and lighter chance of the agent structure of twistlock.

Hereinafter, the present invention is more fully described by means of some preferred embodiments with reference to the accompanying drawings, wherein：

Fig. 1 show specifically the twistlock of the invention in release position.

Fig. 2 shows identical but viewed from abovely with Fig. 1.

Fig. 3 is identical with Fig. 1 but is shown with section view.

Fig. 4 show specifically in wherein it is received impact and the rotated position of locking piece according to this The twistlock of invention.

Fig. 5 shows identical but viewed from abovely with Fig. 4.

Fig. 6 is identical with Fig. 4 but is shown with section view.

Fig. 7 shows the exploded view of twistlock of the invention.

Fig. 8 shows twistlock to the installation in the corner casting of upper and lower container.

Thus, Fig. 1 shows twistlock, and the twistlock is intended to two container corners on the other side of locking, should Two containers are stacked on top of the other for one relative to each other, or the bottom comers of minimum container are locked in erecting bed On counterpart.The main body label 1 of twistlock is marked.Pivoting latch part 2 is in the top of main body 1 of twistlock, and pivoting latch part 3 exists Main body lower section.Combined each other on these stiff shafts 4 shown in Fig. 3 and Fig. 6.Twistlock of the invention be intended for The twistlock identical purpose shown in open DE202012101261U1, its thus have it is shown with the disclosure for discussing Identical is intended to usage.Upper locking member 2 is locked into the corner casting of the bottom comers of upper container, and accordingly, lower locking Part 3 is locked into the corner casting of the top corners of container with per se known manner in the art below, or is locked into peace Fill the counterpart of platform.

Operation lines 6 are connected to the interface 5 on axle 4, by pulling the operation lines, axle 4 and thus locking piece 2,3 also close Rotated in main body 1.By means of operation lines, thus the locking of container part can be opened.Pull-button 7 is fastened to the end of operation lines 6, leads to Cross pull operation line 6, and thus pull the axle 4, locking piece 2,3 can be moved from the pull-button.In this embodiment, will be for for example Two flexible members of helical spring 8 and 9 are installed around operation lines.Operation lines 6 also include end pieces 10, and it prevents the spiral shell against it Rotation spring 9 slips the end of operation lines 6.Additionally, operation lines 6 include compression axle bush 11, it is by means of the convergent part in main body 12 limitation movements of the operation lines towards the inside of main body 1.The convergent part 12 of main body also prevents helical spring 8 from departing from main body.

Have to be noted that instead of two flexible members 8,9, also there may be the flexible member of another quantity, such as spiral bullet Spring.If only in the presence of a flexible member, then interface 5 is separated from one another by the half part of flexible member.Flexible member Half part can have to spring force different from each other in this case.Similarly, it is possible to, in flexible member 8,9 two Person or one by their longitudinal direction for flexible one or more elements are constituted, such as helical spring.Thus can generation For a long helix spring, for example multiple continuous helical springs are used.

Interface 5 on the axle 4 of locking piece 2,3 can be groove, hole or corresponding part, and operation lines can pass through it Slide but on the other hand which limit the movement of helical spring 8,9.

Typically, spring force of the spring force of helical spring 9 than the entopic helical spring 8 of determination locking piece 2,3 It is bigger.By pull operation line 6, helical spring 8 first is compressed while locking piece 2,3 is on body rotation.

Under normal circumstances, as it is observed from fig. 2 that, helical spring 8 widdershins promotes locking piece 2,3, until operation lines 6 Compression axle bush 11 run into the convergent part 12 of main body.

Widdershins rotate farther than normal condition when the locking piece wherein due to external force is met with the control of container Situation when, helical spring 9 compresses (Fig. 4,5 and 6).There is no helical spring 9, the mobile of discussion will be impossible, but Operation lines will rupture.In removed external force, helical spring 9 is by locking piece to pushing back into normal position.

Fig. 7 shows the exploded view of twistlock of the invention, is become more apparent upon from the decomposition graph structure.Main body 1 is by two and half Part is constituted, and spring mechanism is configured inside it.The half part of main body for example using two screw and nuts showing in the figure 7 Mode be combined together.

Fig. 8 shows that wherein twistlock has been attached to the bottom comers casting 13 of container and it is dropped in this embodiment The sketch of the situation as little as on the top of counterpart 14, the counterpart 14 is arranged on such as hatch board, in this case, twistlock Lower locking piece 3 travel across counterpart top surface hole, and be locked into per se known manner in the art The hole.If container is reduced on the top of lower container, then counterpart 14 can also be the top corners casting of lower container.

It will be apparent for a person skilled in the art that the invention is not restricted to embodiment described above, but it can Change in the range of the claim being shown below.

Mechanism of the invention for example can also be performed in following this mode：Replaced with rubber components or other elastomeric elements One or two spring changed in spring.

Further, it is possible to perform spring mechanism of the invention in following this mode：Operation lines are connected to sleeve, its Then be arranged on locking piece in this mode that sleeve can slide into limited degree on locking piece (or to the axle of locking piece On).In that case, it is possible to not carry out the movement of locking piece using the movement of operation lines.Sleeve can be spring-loaded, or The hardness of spring can be selected in following this mode：Used as the result of spring force, sleeve stops the expectation position into relative locking piece Put (perfect condition).
