## Abstract

Hinges for multipurpose golf training aids, and more particularly, long-wearing, durable low-profile hinges for multipurpose golf training aids, and methods for manufacturing such hinges are disclosed.

## Claims

### Claim 1

A method of manufacturing a golf training aid hinge assembly, the method comprising:
providing at least one friction plate having an arm;
providing at least one frictional brake pad disposed in contact with the at least one friction plate, the at least one frictional brake pad having an arm;
providing a force distribution device for holding the at least one friction plate in contact with the at least one frictional brake pad; and
providing a first hinge body element and a second hinge body element; and
positioning the arm of the friction plate such that it extends into the first hinge body element; and
positioning the arm of the frictional brake pad such that it extends into the second hinge body element.

### Claim 2 (depends on 1)

The method of manufacturing a golf training aid hinge assembly of claim 1, the method comprising:
providing an attachment member, wherein the attachment member includes a threaded member for enabling adjustment of a pressure applied by the force distribution device.

### Claim 3 (depends on 2)

The method of manufacturing a golf training aid hinge assembly of claim 2, wherein the at least one frictional brake pad comprises copper-reinforced aramid.

### Claim 4

A method of manufacturing a golf training aid hinge assembly, the method comprising:
providing a first friction plate and a second friction plate, each of the first friction plate and second friction plate having an arm;
positioning a first frictional brake pad in contact with the first friction plate and second friction plate, the first frictional brake pad having an arm;
providing an attachment member and a biasing member for holding the first friction plate and second friction plate in contact with the first frictional brake pad;
providing a first hinge body element and a second hinge body element; and
positioning the arm of the first friction plate such that it extends into one of the first hinge body element and the second hinge body element; and
positioning the arm of the first frictional brake pad such that it extends into one of the first hinge body element and the second hinge body element.
