DK179585B1 - Standard container with a double door - Google Patents

Abstract

Containers are usually fitted with double doors, which in use must both be closed and secured securely in order for the retaining bracket mounted on the doors to be used. The invention covers a closing mechanism on asymmetrical and uneven door joints of the container, as well as on symmetrical door closures, thereby creating a central locking function which opens, closes and secures the container doors in a workflow. closing the container doors is minimal and the workflow is reduced to just one movement. This creates new opportunities for improving the personal and transport safety of such containers.

Description

Standard container with a double door

DESCRIPTION

The present invention relates to a standard double-door container, wherein the double-door has a retracting bracket and a locking device adapted to lock the double-door relative to the frame structure of the container in one operation.

The invention is particularly true in that the door sections of the double door are asymmetrical, and the suspension bracket is fixedly mounted on one door section and centrally located on the double door.

The doors for closing the container are made of asymmetric geometry and fitted with locking / closing piles in conical design. These are operated by manpower by a single movement of a handle after closing the door arrangement.

The effect of the design is that the tapered locking posts ensure that the door lock can engage and the door cannot be locked unless the door is locked properly. The central lock means that the top and bottom of the container door are locked simultaneously. In this embodiment, the door lock is self-locking, so that the door cannot inadvertently open, just as the door does not lock itself when the handle is in open position.

The operation requires the handle to be operated and even persons of low strength could operate the container lock.

Containers with retraction brackets in the door section have traditionally been made with central retention brackets mounted pivotally on one of two almost identical, mirrored doors, each of which requires handling when closing, locking and securing before transport. Such a container is known from Danish patent DK 177470 B1.

This invention ensures that the operation is simplified for the crew and that the safety of both the crew and the equipment during handling of the container is improved.

The invention consists of a door assembly with asymmetrical distribution of right and left door sections, so that a sufficient and even oversized suspension bracket can be mounted, and partly by a control handle which via an exchange both locks and secures both door sections by simultaneously activating tapered locking pallets, which ensures that the door can only be locked correctly, and partly in a workflow, it is possible to open, close and secure both doorways.

The operation is as follows:

1. On the basis of the closed container, the controls with (1) marked on the drawings are lifted and the tapered locking pawls (4) release their engagement with the fixed structure on the container front.

2. The door section, with the hook solution on, must be opened first. This is swung this one all the way up to the right side, then the door part is opened on the left side and swung all the way up to the left, now the container is ready for operation.

3. The container front closure is reversed, the door portion on the left is first closed and then the door portion on the right is fully closed and the control lever (1) is moved into the closed position, now the container is ready for lifting and towing.

Claims (4)

patent claims A standard double-door container, wherein the double-door has a retracting bracket (9) and a locking device adapted to lock the double-door in one operation with respect to the frame structure of the container, characterized in that the double-door door sections (2,3) are asymmetrical, and the catch bracket (9) is fixedly mounted on one door portion (2) and centrally located on the double door. The standard container of claim 1, wherein the locking device comprises a manual control handle (1) in contact with tapered locking pawls (4) which can engage locking holes (6) in the frame structure of the container. Standard container according to any one of the preceding claims, wherein the locking device comprises a central lock. The standard container according to any of claims 2-3, wherein the tapered locking pawls (4) are arranged to retract the double door of the container if it is not fully closed when it is attempted to be locked.
