    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.

  • Patent number: 6116804
    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.

  • Patent number: 4977648
    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.
