Abstract: A foldable portable chair provides users with two side-by-side seats. The supporting framework of the chair includes four support members. The first and second support members are hingeably attached to each other at their upper ends to forman inverted V-shape. The third and fourth support members are hingeably attached to each other at their lower ends to form a V-shape. The first and third support members and the second and fourth support members are then pivotally attached to each other so as to fold in a scissors fashion. A first seat member extends between the first support member and the third support member. A second seat member extends between the second support member and the fourth support member. In the preferred embodiment, the support members are U-shaped, and a storage compartment is suspended between the two seat members.

Abstract: A method and apparatus are disclosed for assembling spring frame hinges that utilize a pin having a tapered self-aligning section, a stepped midsection and a raised diameter stopping element. By harvesting the offsetting tension created by the hinge tang and curls the pin is easily inserted, lockingly held securely in place without the use of any additional fastening technique and yet can be non-destructively disassembled with little difficulty. In preferred embodiments of the invention audio confirmation that the pin has been properly inserted is achieved and a locking flush pin is disclosed.
