Definitions

  • This particular invention has reference to a container lock with the purpose to interlock superposed stacked containers for example on another container or on a platform, during transportation, comprising a lock housing in which a vertical shaft is rotatably mounted when in use.
  • This shaft has a top with an upper gear lock located outside the lock housing and a lower end with a lower gear lock located outside the lock housing whereby the gear locks are to be locked to the oval hole in the container as well as to the underlayer.
  • the aim of this particular invention is to eliminate the above disadvantages concerning convential container locks and to produce a new container lock which can automatically lock a container at the underla er when lowering it towards the un**- derlayer .
  • the above mentioned pro ⁇ blems will bo solved by the fact that a carry-over is fixed at this shaft in the lock housing by means of which the shaft may rotate because of the fact that the lock housing further ⁇ more is furnished with a hydraulic unit with a primary piston as well as with a secondary one in order to be able to effect the above mentioned carry-over, to which the primary piston is located so as to be effected by the weight of the container when lowering it towards the underlayer so that the above loc ⁇ king devices through the above mentioned secondary piston and carry-over, will be automatically turned into locking position, Moreover, the inventive idea will produce a container lock which will be reliable in running, demand a slight effort to perform, create a safer working environment and which will gua ⁇ rantee a considerable durability.

  • Fig. 1 and 2 shows the main parts of the lock in accordance with the invention.
  • the lock comprises a lock housing 1 consisting of two parts 15, 16. Furthermore it shows a hydraulic unit 4 partially projecting from the lock housing and two locking devices 2, 3 located outside the lock housing. These lock devices are comparati ⁇ vely angle and are connected to guiding parts 35, 36 of the lock housing 1, which fit in the existing standarized oval loles (ISO) of the container cornes. If the container is to be locked on a different underlayer, a similar oval hole na ⁇ turally has to be made on the underlayer. In this case the angle is 30 . the housing is also furnished with a manoeuvre device 10, which can be handled from the outside of the lock housing.
  • ISO standarized oval loles
  • the mutual angle position of the locking device leads to the fact that one locking device can be fixed to .
  • an oval ho ⁇ le in the container at the same time as the other locking de ⁇ vice can pass through an adjacent oval hole of an underlaying container as well as the underlayer.
  • lock can hang at the underside of the container, see fig. 14 and 15.
  • Fig. 3 and 4 show the cross-section III-III and IV-IV of the figures 4 and 3.
  • the lock comprises a through shaft 9 located outside the lock housing and on the ends of which the two locking devices 2 and 3 are fixed.
  • the locking device 2 can rotate about its own shaft 9, 30 , whereby locking device 2 in one end position will be paral ⁇ lel to locking device 3.
  • Locking device 2 is loaded to the other end position by means of a leaf spring 21, see fig. 6.
  • locking device 2 has an interior recess 22, which allows the spring 21 to be bent when locking device 2 is brought to a position which is parallel to locking device 3.
  • the main part of the hydraulic unit 4 is also installed in the loch housing 1.
  • the unit comprises a primary piston 7 with quite a large sectional area, a secondary piston 8 with quite a small sectional area, which is perpendicular to the primary piston.

  • the height of the guiding part 35 is adapted so that the piston can be engaged with the underlayer when locking device 3 has passed through the oval hole.
  • locking device 3 as well as shaft 9 can be turned.
  • Owing to the heavy weight of the container primary piston 7 will be pressed into hydraulic unit 4 against the force of spring 20 in the course of the continuos lowering.
  • the existing hyd ⁇ raulic fluid of the hydraulic unit will hereby press the se ⁇ condary piston towards carry-out 5. Owing to the different areas between the primary and the secondary pistons a multi ⁇ plier effect will hereby be obtained, i.e. a slight displace ⁇ ment of secondary piston 8.
  • Secondary piston 8 will then turn carry-out 5 and also shaft 9 clockwise against the force of spring 12.

In this way you will obtain a safe, stable and completely automatic locking of the container on the un ⁇ derlayer.
  • the o- perator When the container is to be lifted from the underlayer the o- perator inserts the tool shown in fig.7 into manoeuvre device 10 in all the locks and turns the tap ⁇ driving .slot 14.into po ⁇ sition 19 shown in fig.4, causing bar 17 to disengage from gear lock 31.
  • the influen ⁇ ce of pull back springs 12 and 20 When finally the container is lifted the influen ⁇ ce of pull back springs 12 and 20 will make carry-out 5 and consequently shaft 9 turn back to starting position as the pri ⁇ mary piston is being relieved from the weight of the container.

Abstract

Dispositif de verrouillage automatique servant à verrouiller réciproquement des conteneurs empilés et superposés notamment sur le pont d'un bateau ou sur une plate-forme pendant le transport, comprenant un logement (1, 1') de verrou dans lequel un axe vertical est monté rotatif lorsqu'on l'utilise. L'axe comporte des parties supérieures et inférieures comprenant respectivement des dispositifs de verrouillage supérieur (2, 2') et inférieur (3, 3') qui sont situés à l'extérieur du logement du verrou. Sur l'axe (9, 9') est fixé un actionneur (5, 5') qui permet à l'axe de tourner. En outre, le logement du verrou comprend une unité hydraulique (4, 4') comportant des pistons primaire (7, 7') et secondaire (8, 8') qui sont fixés de manière à mettre en ÷uvre l'actionneur précité. Le piston primaire est donc fixé de manière à être commandé par le poids du conteneur lorsqu'on le descend jusqu'à la couche inférieure de sorte que les dispositifs de verrouillage (2, 2', 3, 3') se déplacent automatiquement en position de verrouillage par l'intermédiaire du piston secondaire et de l'actionneur.
