The frame assembly includes at least one frame having a first frame opening and a second frame opening. The support structure assembly includes at least one support structure supported by the at least one frame. The at least one support structure includes a mounting portion; a slide engagement member supported by the mounting portion configured to engage the first frame opening; and, at least one snap engagement member supported by the mounting portion configured to engage the second frame opening. The slide engagement member and the at least one snap engagement member are integrally formed with the mounting portion. In another embodiment the orthotic device includes a latch mechanism including a lever assembly, a draw bar, a chafe, a catch, and a first snap fit ledge. ## Claims ### Claim 1 An orthotic device, comprising: a latch mechanism, said latch mechanism, including: a) a lever assembly, comprising: i. a lever; ii. a lever axle depending from said lever at a first end thereof, for securing the lever to a support structure of the orthotic device; and, iii. a first snap fit hook projecting from said lever; b) a draw bar pivotably attached to said lever wherein said draw bar defines a major axis along a length thereof and a minor axis along a width thereof; c) a D-ring chafe pivotably attached to said draw bar around a pivot axis substantially perpendicular to said major axis and said minor axis; d) a catch extending from the support structure to receive said lever axle; and, e) a first snap fit ledge depending from the support structure to engage and hold said first snap fit hook; wherein said catch is configured to stand substantially above a nominal height of the support structure such that the lever axle is easily received by said catch for fastening by the user. ### Claim 2 (depends on 1) The orthotic device of claim 1, wherein said lever assembly comprises a second snap fit hook spaced from said first snap fit hook projecting from said lever. ### Claim 3 (depends on 1) The orthotic device of claim 1, further including a strap attachable to said chafe. ### Claim 4 (depends on 1) The orthotic device of claim 1, wherein said lever and said snap fit hook are integral. ### Claim 5 (depends on 1) The orthotic device of claim 1, wherein said snap fit hook is engaged or released from said snap fit ledge by pulling up on said lever. ### Claim 6 (depends on 1) The orthotic device of claim 1, wherein said lever comprises a push button that functions to engage or release said snap fit hook from said snap fit ledge. ### Claim 7 (depends on 1) The orthotic device of claim 1, wherein said lever comprises a pinch configuration that functions to engage or release said snap fit hook from said snap fit ledge. ### Claim 8 An orthotic device, comprising: a) a frame assembly comprising at least one frame having a first frame opening and a second frame opening; b) a support structure assembly comprising at least one support structure supported by the at least one frame, said at least one support structure including: i. a mounting portion; ii. a slide engagement member supported by said mounting portion configured to engage said first frame opening; and, iii. at least one snap engagement member supported by said mounting portion configured to engage said second frame opening, c) a latch mechanism for securing a strap to the support structure, comprising: i. a lever assembly, comprising: a lever; a lever axle depending from said lever at a first end thereof, for securing the lever to a support structure of the orthotic device; and first snap fit hook projecting from said lever; ii. a draw bar pivotably attached to said lever wherein said draw bar defines a major axis along a length thereof and a minor axis along a width thereof; iii. a D-ring chafe pivotably attached to said draw bar around a pivot axis substantially perpendicular to said major axis and said minor axis; iv. a catch extending from the support structure to receive said lever axle; and v. a first snap fit ledge depending from the support structure to engage and hold said first snap fit hook. ### Claim 9 An orthotic device, comprising: a latch mechanism, said latch mechanism, including: a) a lever assembly, comprising: i. a lever; ii. a lever axle depending from said lever at a first end thereof, for securing the lever to a support structure of the orthotic device; and, iii. a first snap fit hook projecting from said lever; b) a draw bar pivotably attached to said lever wherein said draw bar defines a major axis along a length thereof and a minor axis along a width thereof; c) a D-ring chafe pivotably attached to said draw bar around a pivot axis substantially perpendicular to said major axis and said minor axis; d) a catch extending from the support structure to receive said lever axle; and, e) a first snap fit ledge depending from the support structure to engage and hold said first snap fit hook; wherein said lever axle is received by said catch for fastening by the user. ### Claim 10 (depends on 9) The orthotic device of claim 9, wherein said lever assembly comprises a second snap fit hook spaced from said first snap fit hook projecting from said lever. ### Claim 11 (depends on 9) The orthotic device of claim 9, wherein said lever and said snap fit hook are integral. ### Claim 12 (depends on 9) The orthotic device of claim 9, wherein said snap fit hook is engaged or released from said snap fit ledge by pulling up on said lever. ### Claim 13 (depends on 9) The orthotic device of claim 9, wherein said lever comprises a push button that functions to engage or release said snap fit hook from said snap fit ledge. ### Claim 14 (depends on 9) The orthotic device of claim 9, wherein said lever comprises a pinch configuration that functions to engage or release said snap fit hook from said snap fit ledge.
