Orthotic device for limiting limb notion at a joint

Claim 2

An orthotic device for a limb joint, said device comprising first and second members, said first member being adapted to be attached to that portion of the anatomy to one side of the joint, said second member being formed of plastic sheet material the inner surface of which substantially conforms to that portion of the anatomy to the other side of the joint, a pivotal connection between said first and second members, said pivotal connection having an axis substantially corresponding to an axis of motion of the joint, an abutment carried by said first member, an adjustable stop carried by said second member for limiting pivotal movement between said first and second members, a mounting block carried by said second member, the plastic sheet of said second member being formed closely about said mounting block to hold said block in place, and an adjusting member threadably received in said mounting block and adapted to adjust said stop.

Claim 3

The orthotic device of claim 1 further characterized in that said adjustable stop has oppositely disposed walls, each of said stop walls having a groove therein and the sheet material for said second member is thermoformed closely about said stop walls and into said grooves to provide rails permitting sliding movement of the stop.

Claim 4

The orthotic device of claim 2 further comprising means for connecting said adjusting member to said stop.

Claim 5

The orthotic device of claim 1 further comprising a spring carried in said mounting block and providing a resilient connection between said adjusting member and said stop.

Claim 6

The orthotic device of claim 1 further characterized in that said mounting block has at least one indentation in a surface thereof engageable by the sheet material of said second member, the sheet material of said second member being thermoformed into the indentation in said mounting block for retaining said block on said second member.

Claim 7

An orthotic device for a limb joint, said device comprising first and second members, said first member being thermoformed of plastic sheet material the inner surface of which substantially conforms to that portion of the anatomy to one side of the joint, said second member being thermoformed of plastic sheet material the inner surface of which substantially conforms to that portion of the anatomy to the other side of the joint, a pivotal connection between said first and second members, said pivotal connection having an axis adapted to substantially correspond to an axis of motion of the joint, an abutment carried by said first member, said first member being thermoformed closely about said abutment to hold said abutment in place with its surface substantially flush with adjoining inner surface regions of the first member, an adjustable stop carried by said second member engageable with said abutment for limiting pivotal movement between said first member and said second member, a mounting block carried by said second member, said second member being thermoformed closely about said mounting block to hold said block in place with its inner surface substantially flush with adjoining inner surface regions of said second member, and an adjusting member threadably received in said mounting block and adapted to adjust said stop.

Claim 8

An orthotic device for a limb joint, said device comprising first and second members, said first member being thermoformed of plastic sheet material the inner surface of which substantially conforms to that portion of the anatomy to one side of the joint, said second member being thermoformed of plastic sheet material the inner surface of which substantially conforms to that portion of the anatomy to the other side of the joint, a pivotal connection between said first and second members, said pivotal connection having an axis adapted to substantially correspond to an axis of motion of the joint, an abutment carried by said first member, said first member being thermoformed closely about said abutment to hold said abutment in place with its surface substantially flush with adjoining inner surface regions of the first member, an adjustable stop carried by said second member engageable with said abutment for limiting pivotal movement between said first member and said second member, a mounting block carried by said second member, said second member being thermoformed closely about said mounting block to hold said block in place with its inner surface substantially flush with adjoining inner surface regions of said second member, and an adjusting member threadably received in said mounting block and adapted to adjust said stop.

Claim 9

The orthotic device of claim 6 further characterized in that said adjustable stop has oppositely disposed walls, each of said stop walls having a groove therein and sheet material of said second member is thermoformed closely about said stop walls and into said grooves to provide rails permitting sliding movement of the stop.

Claim 10

The orthotic device of claim 7 further comprising means for connecting said adjusting member to said stop.

Claim 11

The orthotic device of claim 6 further comprising a spring carried in said mounting block and providing a resilient connection between said adjusting member and said stop.

Claim 12

The orthotic device of claim 6 further characterized in that said mounting block has at least one indentation in a surface thereof engageable by the sheet material of said second member, the sheet material of said second member being thermoformed into the indentation in said mounting block for retaining said block on said second member.
