Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
323 words
A trailer apparatus adapted for connection with a towing vehicle to effect desired movement of a cargo or load positioned on the trailer apparatus, including: a. an axle housing rotatably mounting a pair of spaced wheels for supporting said axle housing; b. a support frame mounted with said axle housing for supporting the load on said axle housing; c. a drawbar assembly connected with said support frame including: 1. a first substantially vertical member having a first lower end connected with said support frame; and 2. a second substantially vertical member laterally spaced from said first substantially vertical member with each of said vertical members having a first lower end connected with said support frame; 3. a first gooseneck forming member having a substantially horizontal first position connected with said substantially vertical member at a location spaced from the connection of said substantially vertical member with said frame and extending from said substantially vertical member to a second portion of said gooseneck forming member which angles downwardly from said substantially horizontal first portion at an angle greaTer than 30* and less than 40* to said hitch means; 4. a second gooseneck forming member laterally spaced from said first gooseneck forming member and having a substantially horizontal first portion connected with said second substantially vertical member at a location spaced from the connection with said support frame and extending from said second substantially vertical member to a second portion of said second gooseneck forming member which angles downwardly from said substantially horizontal first portion of said second gooseneck forming member at an angle greater than 30* and less than 40* to said hitch means whereby operator visibility, usable cargo space, and overall length is enhanced; and d. hitch means mounted on said drawbar assembly at a location spaced from said support frame for releasably connecting said drawbar with the towing vehicle wherein towing force is imparted to said trailer apparatus for effecting movement thereof.
Claim 2
Dependent Claim
323 words
A trailer apparatus adapted for connection with a towing vehicle to effect desired movement of a cargo or load positioned on the trailer apparatus, including: a. an axle housing rotatably mounting a pair of spaced wheels for supporting said axle housing; b. a support frame mounted with said axle housing for supporting the load on said axle housing; c. a drawbar assembly connected with said support frame including: 1. a first substantially vertical member having a first lower end connected with said support frame; and 2. a second substantially vertical member laterally spaced from said first substantially vertical member with each of said vertical members having a first lower end connected with said support frame; 3. a first gooseneck forming member having a substantially horizontal first position connected with said substantially vertical member at a location spaced from the connection of said substantially vertical member with said frame and extending from said substantially vertical member to a second portion of said gooseneck forming member which angles downwardly from said substantially horizontal first portion at an angle greaTer than 30* and less than 40* to said hitch means; 4. a second gooseneck forming member laterally spaced from said first gooseneck forming member and having a substantially horizontal first portion connected with said second substantially vertical member at a location spaced from the connection with said support frame and extending from said second substantially vertical member to a second portion of said second gooseneck forming member which angles downwardly from said substantially horizontal first portion of said second gooseneck forming member at an angle greater than 30* and less than 40* to said hitch means whereby operator visibility, usable cargo space, and overall length is enhanced; and d. hitch means mounted on said drawbar assembly at a location spaced from said support frame for releasably connecting said drawbar with the towing vehicle wherein towing force is imparted to said trailer apparatus for effecting movement thereof.
Claim 3
Dependent Claim
29 words
a second substantially vertical member laterally spaced from said first substantially vertical member with each of said vertical members having a first lower end connected with said support frame;
Claim 4
Dependent Claim
29 words
a second substantially vertical member laterally spaced from said first substantially vertical member with each of said vertical members having a first lower end connected with said support frame;
Claim 5
Dependent Claim
37 words
The structure as set forth in claim 1, wherein: the connection of each of said substantially horizontal first portion of each of said gooseneck forming member with the respective substantially vertical member substantially forms a right angle.
Claim 6
Dependent Claim
77 words
The structure as set forth in claim 1, including: a first and second reinforcing member with said first reinforcing member having a first end secured with said first substantially vertical member and a second end secured with said substantially horizontal portion of said first gooseneck member, said second reinforcing member connected to said second substantially vertical member at a first end and connected at a second end with said substantially horizontal portion of said second gooseneck member.
Claim 7
Dependent Claim
71 words
a first gooseneck forming member having a substantially horizontal first position connected with said substantially vertical member at a location spaced from the connection of said substantially vertical member with said frame and extending from said substantially vertical member to a second portion of said gooseneck forming member which angles downwardly from said substantially horizontal first portion at an angle greaTer than 30* and less than 40* to said hitch means;
Claim 8
Dependent Claim
71 words
a first gooseneck forming member having a substantially horizontal first position connected with said substantially vertical member at a location spaced from the connection of said substantially vertical member with said frame and extending from said substantially vertical member to a second portion of said gooseneck forming member which angles downwardly from said substantially horizontal first portion at an angle greaTer than 30* and less than 40* to said hitch means;
Claim 9
Dependent Claim
50 words
The structure as set forth in claim 3, wherein: each of said reinforcing members is a plate for connection with said substantially vertical member along a first edge of said plate and with a second edge of said plate connecting with said substantially horizontal portion of said gooseneck forming member.
Claim 10
Dependent Claim
135 words
a second gooseneck forming member laterally spaced from said first gooseneck forming member and having a substantially horizontal first portion connected with said second substantially vertical member at a location spaced from the connection with said support frame and extending from said second substantially vertical member to a second portion of said second gooseneck forming member which angles downwardly from said substantially horizontal first portion of said second gooseneck forming member at an angle greater than 30* and less than 40* to said hitch means whereby operator visibility, usable cargo space, and overall length is enhanced; and d. hitch means mounted on said drawbar assembly at a location spaced from said support frame for releasably connecting said drawbar with the towing vehicle wherein towing force is imparted to said trailer apparatus for effecting movement thereof.
Claim 11
Dependent Claim
