Problems solved by technology

[0015] For example, some latches may require relatively low resistance to actuating the latch, but relatively high resistance to holding
The prior art does not show that a latching device is capable of effectively exhibiting a variable latching resistance as the spring moves away from its relaxed position

Embodiment Construction

[0069] Referring now in particular to the drawings, the present invention provides a latch arrangement or assembly 10 for releasably securing a cargo container (not specifically shown) to a support surface (indicated at 25). The latch arrangement comprises a housing 11, a latch member 12, a pin 13, a first compression spring 14 and two side screws (designated 15 and 37). A side screw 15 and 37 is on one side of the housing 11 . The housing 11 includes the upper part of the container passing through the housing (indicated at 44) and the interior of the coil receiving cavity (indicated at 42). Housing 44 is receivable by latch drive opening 46 and defines a flared latch receiving cavity (indicated at 47 ).

[0070] figure 1 An assembled front view of the latch device 10 is shown in figure 2 An assembled side view of the latch device 10 is shown. The housing 11 also includes a base bottom 16 that interfaces with a deck or vehicle or similar flat surface (indicated as surface...

Abstract

A latch device releasably secures a container to a support surface. The device comprises a housing, a latch, interchangeable spring sets, and a pin. The housing comprises an upper shell and an inner coil-receiving cavity. The shell defines a latch-receiving cavity. The latch comprises an upper latch end and a coil-engaging portion. The coil-engaging portion comprises coil-aligning structure. At least one compression coil is received within the coil-receiving cavity and placed into engagement with the coil-engaging portion so as to bias the upper latch end exterior to shell via the latch-receiving cavity. The coil-aligning structure enhances axial alignment of each coil during coil compression. The pin pivotally connects the latch to the housing for enabling pivotal movement of the latch under selectively varied spring resistance for targeted applications. The coil(s) thus enable the user to vary latching forces during latching securement and release depending to the targeted loads and conditions.

Description

technical field [0001] The present invention relates to container securing devices and, in particular, to improvements in cargo container securing devices which provide automatic securing and release of cargo containers. Background technique [0002] Container loading has become very popular due to several advantages such as labor savings due to reduced cargo handling. Modular or standard containers can be shipped point-to-point using a variety of different carriers including railcars, trucks and ships. Such cargo containers are often provided with corner castings which include locking openings for securing the container to various types of vehicles on which the container is loaded. [0003] One type of container securing device used in the past is the container pedestal, which consists of a base portion on which the corners of the container rest and vertically extending walls on which the corners of the container are captured. intramural. A latch pivotable about a horizo...
