ABSTRACT:
A method of rigidly fixing an end portion of an elongated column member within a cavity in a body member. A quantity of hardenable adhesive material is placed into the cavity such that when the column member end portion is inserted into the cavity, the resulting displacement of a portion of the adhesive material causes the adhesive material substantially exactly to fill the cavity. The column member end portion is then inserted into the cavity, and the adhesive material is allowed to harden. The angular position of the column member relative to the body member can be adjusted as desired prior to hardening of the adhesive material. Preferably, the method is automated, including injecting a measured amount of adhesive material into the cavity and holding the column member and the body member in a jig while the adhesive material hardens. The adhesive material can be an epoxy resin, and if desired, the hardening can be accomplished by heat curing. The body member might be formed of nylon, and the column member might be formed of steel. The method is particularly suited for forming shoe supports such as shoe heel structures, each including an upper support member, a lower support member, and a plurality of elongated column members. Two or more column members may be fastened within a single cavity, if desired.
