21	Ninety degree turn fastener	US486373	1990-02-28	US5020196A	1991-06-04	Rafael B. Panach; Rafael B. Royo
The present invention relates to a ninety degree turn fastener composed of two parts made of resistant materials, either metal or other, which meet the technical requirements to allow their machining in order that they may fulfill their purpose; once the parts have been machined and by the nature of the functions they perform within the fastener, we shall call them females and male, with the same outline shapes to ensure that they match; the face of the female part in its central area is made up of a raised flat surface with a concave rear side to accommodate the wings of the male part, this being surrounded by another dish-shaped plane, which constitutes the base for attachment of the fastener; the center of the front face has a rectangular opening, with a width appropriate for carrying out its purpose, and approximately three times as long as it is wide. The outer attachment plate has a groove with several holes distributed along it, and a number of clamps for attachment, whether it be by sewing or by any other means; the male part is flat on its rear side; from the center of the face there protrudes a round nucleous measuring the same as the width of the opening in the female part, which opening matches the central nucleous ended in a T shape, whose wings are sufficiently separated from the base plate as to clear the side faces of the female opening when turning through 90 degrees in order to fasten; the length is equal to that of the female opening; the means of attachment of the male part to its corresponding piece of garment are the same as the means of attachment of the female part to its corresponding piece.

A fastening device comprises a base portion and a key portion, the base portion having a socket opening therein with a radial shoulder. At least an axial portion of the socket opening is in the form of a regular polyhedron, preferably 12 or 16 sided. The key portion has a furcated post, axial portions thereof being generally conformed to at least portions of the polyhedral socket. The post has a radial shoulder which snaps behind the shoulder of the socket to retain the key in position. As the key is rotated the post interferes in a periodic manner with the socket wall, thereby precluding the key from being accidentally turned. The device may suitably be molded from a resilient thermoplastic resin. The device may also comprise an eye within which the key is received, the eye comprising opposed washer like members the one having serrated posts upstanding therefrom, the other openings for receiving the posts therein in locked relationship.
30	Clamping device for use in packaging	US577552	1975-05-14	US3990131A	1976-11-09	Kouich Okamura
The invention discloses a three-piece clamping device especially adapted for clamping together an inner packing box and an outer packing box or clamping together the packing boxes. The clamping device comprises a pair of rectangular retaining members similar in construction and a retaining wedge member with a knob or wing. According to one preferred embodiment, each retaining member has a saucer-shaped flat-bottomed barrel portion formed by a drawing operation, and a flange portion extending outwardly from the periphery of the open end of the barrel portion. An elongated-hexagon-shaped slot is formed through the flat bottom of the barrel portion, a projection is extended outwardly from the outer bottom surface and a recess is formed in the outer bottom surface of the barrel portion. The retaining wedge member has a wedge-shaped portion and a wing- or knob-shaped portion joined to the shorter base of the wedge-shaped portion, the longer base of which is slightly shorter than the length of the elongated-hexagon-shaped slot. The barrel portions of the retaining members are fitted into the holes formed through the side walls of the inner and outer packing boxes in such a manner that the outer bottom surfaces of the barrel portions are made into very close contact with each other and the projections are fitted into the mating recesses. Thereafter the retaining wedge member is inserted into the slots and rotated through 90.degree. so that the retaining members are drawn to each other, thereby clamping the inner and outer packing boxes.

The slide locking means is provided with a first engaging portion capable of engaging a first portion of the housing locking means which prevents movement in only a first direction along the length of the housing and a second engaging portion capable of engaging a second portion of the housing locking means which prevents movement in only a second direction along the length of the housing.
39	Quick release fastener	US735561	1991-07-25	US5134757A	1992-08-04	Charles R. Johnson
A fastener having five parts. A flexible material such as canvas is apertured at a point of connection and a first washer having a boss axially receives the apertures so that the material overlies the washer. The material is held in sandwiched relation between the first washer and a second washer, both of which having gripping surfaces that engage the material. The washers are pressed downwardly by a knob. The knob has a depending central post that releasably engages a lock member that is in turn releasably engaged by a base member that is secured to a support surface. The lock member has a boss part with an annular step that supports the first washer. A pair of flanges extend from a bottom end of the lock member and are engaged by overhanging walls formed in the base member when the knob is turned. The flanges are arcuate so that they resist flattening when the knob is pressed downwardly, and the resistance pushes the washer members upwardly against the downward pushing of the knob, thereby tightly squeezing the material captured between the washer members.
