Abstract

A method for connecting at least two structural parts of an orthopedic component, wherein the structural parts are retained in an orienting device while oriented in relation to each other, and an intermediate space thus being formed between the structural parts. The orienting device and the structural parts together form a cavity, which has a flow connection to at least one feed connection, via which an adhesive for adhesively bonding the structural parts is introduced into the cavity.

First claim

The invention claimed is:

1. An orthopedic component, comprising:
first and second structural parts; and
an orienting device configured to orient the structural parts relative to each other,
the orienting device comprising:
a hollow space defined by interior surfaces of the orienting device; and
an opening along a top surface of the orienting device, the opening being covered by the first structural part, the hollow space comprises a closed end and at least one insertion opening to receive the second structural part extending into the hollow space, the orienting device being adhesively bonded to the structural parts with adhesive received in the hollow space.

2. The orthopedic component of claim 1 , wherein the interior surfaces of the orienting device that define the hollow space have a shape that corresponds to contoured surfaces of the structural parts.

3. The orthopedic component of claim 1 , wherein the structural parts comprise leaf springs.

4. The orthopedic component claim of 1 , wherein at least one of the structural parts is surrounded on a plurality of sides by the adhesive.

5. The orthopedic component claim of 1 , wherein the orthopedic component is a prosthetic foot or an orthotic component.

6. The orthopedic component claim of 1 , wherein the orienting device bears against or surrounds at least one of the structural parts on at least three sides.

7. The orthopedic component claim of 1 , wherein the structural parts comprise fiber-reinforced plastic components.

8. The orthopedic component claim of 1 , wherein the orienting device comprises a functional component.

9. The orthopedic component claim of 1 , wherein the adhesive comprises a resilient material.

10. The orthopedic component claim of 1 , wherein the orienting device includes spacers to space apart the structural parts from each other.

11. The orthopedic component claim of 1 , wherein the adhesive completely fills the hollow space.

12. The orthopedic component of claim 1 , wherein the closed end is a closed distal end, and at the least one insertion opening is at a proximal end to receive the second structural part.
