This application claims priority to German Patent Application Nos. 10 2009 013 783.1, filed Mar. 18, 2009, and 10 2009 018 658.1, filed Apr. 23, 2009, which are both hereby incorporated by reference.
BACKGROUND AND SUMMARYThe present disclosure relates to a locking device for a lid (also referred to herein as a lid locking device) used, for example, with a transporting container.
A generic locking device for a lid used with a transporting container requires enhancement in that the opened lid of the transporting container may inadvertently close due to an insufficient locking mechanism when loading and unloading the container, which results in a risk of injury.
It is therefore an object underlying the present disclosure to provide a locking device for a lid used with a transporting container that enables a reliable arrest of the opened lid.
The lid locking device of the present disclosure provides a flexible locking spring at the bottom of one of the hinge-joint portions and enables therewith that a bracket member or arm is guided to, and retained at, a locking position corresponding to the opened position of the lid by this locking spring.
Further details, features, and advantages of the present disclosure will be evident from the following description with reference to the drawings, in which:

Accordingly, the locking device for a lid of the present disclosure is thus able to securely lock the lid of a transporting container in an opened position as to prevent the lid from closing inadvertently when loading and unloading the container. When closing the lid of the transporting container, the arrest of the pivoting bracket 4 can be released without any large effort.
Moreover, some embodiments of the present disclosure comprise a locking device for a lid 1 used in a transporting container, comprising a first half-shell 2 and a second half-shell 3, a pivoting bracket 4, a hinge-joint 5 including a first hinge-joint portion 6 at which the first half-shell 2 is attached and a second hinge-joint portion 7 at which the second half-shell 3 is attached, and which pivotally retains the pivoting bracket 4 at the second half-shell 3, wherein a locking spring 8 is arranged at the first hinge-joint portion 6, which spring co-operates with a first bracket arm 9 of the pivoting bracket 4, said first bracket arm being arranged opposite to a second bracket arm 10 retained by the second hinge-joint portion 7.
The second hinge-joint portion 7 located above the second half-shell 3 comprises two recesses 16a and 16b that are located to be offset from the recesses 15a and 15b in the second half-shell 3. Regarding the plane of the hinge-joint portion 7, these recesses 16a and 16b comprise a first wall portion 24 slanting downwardly, a second substantially horizontal wall portion 25 and a third wall portion 26 slanting upwardly, respectively.
The first, second and third wall portion 21, 22 and 23 in the bottom portion 3a of the second half-shell 3 and the first, second and third wall portion 24, 25 and 26 of the recesses 16a and 16b in the second hinge-joint portion 7 form a receiving space 20 in which the second bracket arm 10 of the pivoting bracket 4 is retained stationary and rotatably. The before described configuration of the second half-shell 3 can be combined with the first half-shell 2 described in connection with
It will be appreciated that the embodiment of
