Abstract: A locking device includes a projecting member and a retaining member. The projecting member has a bulbous head which is securely retained by the retaining member which includes a body portion having a passageway or void formed therethrough. An interference defined by at least one embossment is disposed within the passageway to provide a reduced diameter portion which precludes separation of the projecting member from the retainer. Depending on the materials of construction the interlocking relationship between the projecting member and the retainer can be permanent.

Abstract: The rings of a loose leaf ring binder are selectively locked and unlocked by a locking member which travels within a slot on the spine of the ring binder. The leaf springs of the loose leaf ring binder have notches formed below a portion of the slot. Therefore, when a W-shaped locking prong of the locking member is aligned with the notches, the leaf springs can freely flex upwardly and downwardly allowing the rings of the loose leaf ring binder to open and close. However, when the W-shaped locking prong is not aligned with the notches, the W-shaped locking prong is urged against the leaf springs thereby maintaining the leaf springs in a downward position thereby locking the rings of the loose leaf ring binder in a closed position. The locking member further includes a locking tab to maintain the locking member within a locked position within the slot.

Abstract: An arrangement for a snap lock includes a first component having a projecting part that is capable of being introduced into a corresponding cavity in a second component. An indentation in the projecting part is oriented transverse to the direction of introduction into the cavity. A snap device, e.g., a piece of profile strip made of flexible material such as plastic or rubber, is introduced into an undercut groove in the wall of the cavity, wherein a portion of the strip corresponding to the indentation extends into the cavity, thereby producing a snap locking function between the components when introduced one into the other. The components are preferably formed of pieces cut to identical lengths from two extruded profile strips made of rigid material, such as plastic or light metal.

Abstract: A buckle assembly composed of three components, i.e. a socket, a main plug and an auxiliary plug for releasably connecting three straps or belts. The socket includes a cantilevered resilient locking arm interlockingly engageable with a resilient locking tongue of the main plug when the locking tongue is received in a guide chamber in the socket to thereby couple the socket and the main plug. The auxiliary plug is slidably mounted on the main plug and having two resilient, inwardly deformable locking legs snappingly engageable with respective retaining projections of the socket when the locking legs are received in the guide chamber. The auxiliary plug further includes a resilient releasing leg extending parallel to the locking legs and having a releasing cam projection engageable with the resilient locking arm to flex the latter outwardly away from the guide chamber for releasing the locking arm from interlocking engagement with the locking tongue, thereby uncoupling the main plug and the socket.

Abstract: A female member of a snap fastener comprising a holding part to be retained on material and a fitting part provided with a through-hole substantially at its center for closely contacting a fitting head of a male body of the snap fastener. The holding part includes an upper edge inclined to accept the fitting head of the male body and is molded with an elastic synthetic resin in one unit. Since the fitting convex part is inclined in the direction for receiving the fitting head of the male body, it is easy for the fitting head of the male body to slip into the through-hole when inserting the fitting head of the male body, thereby facilitating engagement.

Abstract: An improved clip for clamping papers has a pair of generally T-shaped clamping members each having a clamping portion and two lugs, a pivot pin for interconnecting pivotally the lugs of the clamping members, and a torsion spring mounted on the pivot pin for biasing the clamping portions of the clamping members to abut against each other. The improvement wherein an end of the pivot pin has two axially spaced annular flanges between which the pivot pin passes through a lug of a clamping member and a lug of the other clamping member. The pair of lugs disposed between the flanges are biased by the torsion spring to move in opposite directions and in turn to clamp tightly the pivot pin between the flanges, thereby preventing one of the flanges from outward movement by the obstructing action of the lugs between the flanges.

Abstract: A clutch is disclosed consisting of two parts, the first part being a tubular shell closed at one end, the shell having therein a resilient female clutch member that is held in position by lips on the open end of the shell. A male member is provided which is adapted to be received within the resilient member. The resilient member within the shell is cylindrical of a longitudinal dimension less than the space within the shell and of an outside diameter less than the inside diameter of the shell. The male member is made of a size so that the sum of its diameter plus the wall thickness of the resilient clutch member is greater than the inside diameter of the tubular shell, so as to create an airtight joint when the male member is inserted within the resilient member, but yet permitting air to escape around the outside of the resilient member and retarded ony when disengagement is attempted, at which time the resilient clutch member will seal against the lip of the tubular shell.

Abstract: An apparatus is provided for retaining lamellar material in stacked form. The device includes a sectional rail with a J-shaped cross section, which rail forms the main body of the device. The retaining action of the device is provided by a clamping rail with an L-shaped cross section. In the vicinity of its apex, the L-shaped clamping rail is pivotally mounted at the end of the shorter leg of the J-shaped sectional rail so that the longer legs of the two rails are in opposed, spaced relationship with the shorter leg of the L-shaped rail extending therebetween. An actuating member is coupled to the shorter leg of the L-shaped clamping rail and includes a threaded shaft which extends through a hole in the arcuate or web portion of the J-shaped sectional rail. The threaded shaft is capped with a wing nut which permits adjustment of the device. In operation, the stack of lamellar material is inserted between the longer legs of the two rails and the wing nut is screwed down onto the threaded shaft.
