Abstract

Abstract Disclosed is a unique assembly of latches to be used in association with a fabric door of a cargo container. A first set of latches of the button and key slot type are presented in spaced relationship with the buttons fixedly attached to a shelf or framework of the cargo container and the key slots fixedly attached to a reinforcing bar traversing the fabric door. By appropriately positioning the reinforcing bar with respect to the buttons all of the button-key slot engagements may be actuated simultaneouly along the entire length of the shelf. The bottom of the fabric door has a bar attached thereto, the bar having a tongue protruding therefrom. A groove is presented in the framework of the cargo container such that a tongue and groove engagement may be made along the base. Latches at each end of the bottom bar engage with the framework of the container so as to maintain the tongue and groove engagement at the base.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 134 words
A latch system for use on a cargo container having a frame work, base, and a fabric door for closing an opening allowing access to the interior thereof, comprising: a first rigid member connected to and horizontally traversing the fabric door and dividing the door into at least two sections; a plurality of first latch assemblies connected to and spaced along the first rigid member; a second rigid member connected to and horizontally traversing the fabric door at the bottom thereof; and a plurality of second and third latch assemblies connected to the second rigid member, the second latch assemblies securing the positioning of the fabric door over the opening and the third latch assemblies, separate and distinct from the second latch assemblies and interposed therebetween, maintaining the engagement of the second latch assemblies.
Claim 2
Dependent Claim 134 words
A latch system for use on a cargo container having a frame work, base, and a fabric door for closing an opening allowing access to the interior thereof, comprising: a first rigid member connected to and horizontally traversing the fabric door and dividing the door into at least two sections; a plurality of first latch assemblies connected to and spaced along the first rigid member; a second rigid member connected to and horizontally traversing the fabric door at the bottom thereof; and a plurality of second and third latch assemblies connected to the second rigid member, the second latch assemblies securing the positioning of the fabric door over the opening and the third latch assemblies, separate and distinct from the second latch assemblies and interposed therebetween, maintaining the engagement of the second latch assemblies.
Claim 3
Dependent Claim 42 words
A latch system as recited in claim 1 wherein the first latch assemblies comprise a plurality of key hole plates fixedly secured to the first rigid member, the fabric door being interposed and secured between the plates and the first rigid member.
Claim 4
Dependent Claim 45 words
A latch system as recited in claim 1 wherein the second latch assemblies are connected to each end of the rigid member, each comprising a tongue engaged with a groove, the groove being within a plate fixedly attached to the base of the cargo container.
Claim 5
Dependent Claim 26 words
A latch system as recited in claim 3 wherein the tongue has attached to the end thereof a roller for making rolling engagement within the groove.
Claim 6
Dependent Claim 37 words
A latch assembly as recited in claim 3 wherein the third latch assemblies comprise slide latch mechanisms positioned between the second latch assemblies and making latching engagement with studs fixedly attached to the framework of the container.
Claim 7
Dependent Claim 40 words
A latch system as recited in claim 3 wherein each of the third latch assemblies comprises an elastic strap connected to the second rigid member and a slide fixedly attached to the elastic strap and having a keyhole slot therein.
Claim 8
Dependent Claim 118 words
A cargo container latch system for use on a cargo container having a base, framework, and fabric door covering an opening to the interior of the container, comprising: a first beam horizontally traversing the fabric door; a plurality of first latches spaced along and connected to the first beam; a second beam connected to and traversing the bottom of the fabric door and making sealing engagement with the base of the cargo container; a tongue and groove latch assembly connected to each end of the second beam and fixing engagement of the second beam with the framework; and slide latch assemblies interposed between the tongue and groove latches and maintaining engagement of the tongue and groove latch assemblies.
Claim 9
Dependent Claim 118 words
A cargo container latch system for use on a cargo container having a base, framework, and fabric door covering an opening to the interior of the container, comprising: a first beam horizontally traversing the fabric door; a plurality of first latches spaced along and connected to the first beam; a second beam connected to and traversing the bottom of the fabric door and making sealing engagement with the base of the cargo container; a tongue and groove latch assembly connected to each end of the second beam and fixing engagement of the second beam with the framework; and slide latch assemblies interposed between the tongue and groove latches and maintaining engagement of the tongue and groove latch assemblies.
Claim 10
Dependent Claim 56 words
The cargo container latch system as recited in claim 7 wherein each slide latch assembly comprises an elastic strap fixed to the second beam and a slide having a keyhole slot therein fixed to the elastic strap, the slide having a handle protruding therefrom for restricting movement of the slide by engagement with the first beam.
Claim 11
Dependent Claim 28 words
The cargo container latch system as recited in claim 7 wherein the tongue and groove latch assemblies include a tongue having a roller connected to the end thereof.
Claim 12
Dependent Claim 62 words
The cargo container latch system as recited in claim 7 wherein the cargo container has a plurality of studs extending flush with the opening in horizontal spaced relationship and wherein the first latches are similarly spaced along the first beam, the first latches being keyhole latches such that actuation of all such keyhole latches with the extending studs may be simultaneously achieved.
