Abstract
Abstract A folding vehicle structure includes a frame having a plurality of members. A first member intersects a second member at a first pivot point. A third member, spaced from the first and second members, intersects a fourth member, which is also spaced from the first and second members, at a second pivot point. The frame includes a first cross-member extending between the first and second intersection points. The frame is collapsible.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
164 words
A folding vehicle structure comprising: a frame having a first member, a second member intersecting the first member at a first pivot point, a third member spaced from the first and second members, and a fourth member spaced from the first and second members, wherein the fourth member intersects the third member at a second pivot point, wherein the frame includes a first cross-member extending between the first and second pivot points, wherein the frame includes a second cross-member and a third cross-member, each extending between at least one of the first member and the second member and at least one of the third member and the fourth member; and a latching mechanism disposed on the frame and at least partially extending between the second cross-member and the third cross-member and configured to prevent the frame from collapsing when the latching mechanism is engaged with the frame, wherein the latching mechanism further includes a cable extending from the third cross-member to the second cross-member.
Claim 2
Dependent Claim
164 words
A folding vehicle structure comprising: a frame having a first member, a second member intersecting the first member at a first pivot point, a third member spaced from the first and second members, and a fourth member spaced from the first and second members, wherein the fourth member intersects the third member at a second pivot point, wherein the frame includes a first cross-member extending between the first and second pivot points, wherein the frame includes a second cross-member and a third cross-member, each extending between at least one of the first member and the second member and at least one of the third member and the fourth member; and a latching mechanism disposed on the frame and at least partially extending between the second cross-member and the third cross-member and configured to prevent the frame from collapsing when the latching mechanism is engaged with the frame, wherein the latching mechanism further includes a cable extending from the third cross-member to the second cross-member.
Claim 3
Dependent Claim
83 words
The folding vehicle structure of claim 1 , wherein the first member and the second member are configured to rotate about the first pivot point and the third member and the fourth member are configured to rotate about the second pivot point to collapse or expand the frame, wherein the latching mechanism is configured to prevent rotation of the first member and the second member about the first pivot point and the third member and the fourth member about the second pivot point.
Claim 4
Dependent Claim
22 words
