Abstract
Abstract An arrangement consisting of coupling elements allowing both pitch and yaw pivotal motion between two coupled modules or coaches, is disclosed. A transverse rod located at the end portion of one module is rigidly secured to a pair of arms and is supported thereby. These arms are rigidly connected to a king-post located in a casing. The king-post is adapted to pivot about its vertical axis. The end portion of the other module is provided with a pair of longitudinally-oriented shafts, each having an outer end provided with a pair of jaw members. The latter can open and close to effect coupling of the modules and are adapted to pivotally grip jaw-receiving portions on the transverse rod.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
219 words
An articulated coupling means for a first elongated and a second elongated coach adapted to be linked together; said articulated coupling means comprising a first assembly of coupling elements, carried by one end of said first coach, a complementary second assembly of coupling elements carried by one end of said second coach; said first assembly including an upright king-post rotatably mounted in a rigid casing secured to said one end of said first coach; bearing means provided in said casing to allow said king-post pivotal movement about its vertical axis; a transverse substantially horizontal rod rigidly secured to the upper portion of said king-post and extending on each side of said post; two jaw-receiving sleeves surrounding said rod on opposite sides of said king-post; said second assembly including a pair of parallel, spaced-apart and longitudinally-oriented rigid shafts mounted on said one end of said second coach, each shaft having an outer end, each said outer end being provided with a pair of articulated jaw members which, when closed, define a transverse circular opening, actuating means to open and close each said pair of jaw members, the latter being adapted to grasp said jaw-receiving sleeves; and a second bearing means between said jaw-receiving sleeves and said rod thereby allowing pitch movement between the said first and second assembly of elements.
Claim 2
Dependent Claim
219 words
An articulated coupling means for a first elongated and a second elongated coach adapted to be linked together; said articulated coupling means comprising a first assembly of coupling elements, carried by one end of said first coach, a complementary second assembly of coupling elements carried by one end of said second coach; said first assembly including an upright king-post rotatably mounted in a rigid casing secured to said one end of said first coach; bearing means provided in said casing to allow said king-post pivotal movement about its vertical axis; a transverse substantially horizontal rod rigidly secured to the upper portion of said king-post and extending on each side of said post; two jaw-receiving sleeves surrounding said rod on opposite sides of said king-post; said second assembly including a pair of parallel, spaced-apart and longitudinally-oriented rigid shafts mounted on said one end of said second coach, each shaft having an outer end, each said outer end being provided with a pair of articulated jaw members which, when closed, define a transverse circular opening, actuating means to open and close each said pair of jaw members, the latter being adapted to grasp said jaw-receiving sleeves; and a second bearing means between said jaw-receiving sleeves and said rod thereby allowing pitch movement between the said first and second assembly of elements.
Claim 3
Dependent Claim
42 words
An articulated coupling means as claimed in claim 1, wherein said rod is secured to said king-post forwardly of the latter by a pair of elbow-shaped arms secured to said king-post at one end and to said rod at its other end.
Claim 4
Dependent Claim
29 words
An articulated coupling means as claimed in claim 1, wherein each said jaw member consists of an upper jaw and a lower jaw, each having a mutually-facing semi-circular recess.
Claim 5
Dependent Claim
84 words
An articulated coupling means as claimed in claim 1 or 2 wherein said first and second coaches both have at their ends upper and lower lateral wall edges and a roof portion edge, said lower lateral wall edges downwardly and inwardly extending relative to said upper lateral wall edges, and further including an inverted U-shaped concertina vestibule secured to said roof portion edge and to said upper lateral wall edges, and an inflatable flexible gusset-shaped wall member secured to each lower lateral wall edge.
