  • Patent number: 6196755
    Abstract: The invention provides a locking device for locking two matching lens cell halves of a lens cell. In particular, the invention resides in clips which are located at the joint where the two cell halves mate. The clips, which are molded as part of each cell half, are each comprised of a male member which is inserted into a female member. The male member includes a flexible tab which is deflected when inserted into the female member. After insertion, it is maintained in a deformed state, that is the tab is maintained by the female member so that it is bent from its original position. As a result, a bending moment is induced and maintained in the tab and that moment pushes the tab against an outer wall of the female member. Consequently, forces are established which lock the male member in place. Additionally, the wall of the female member exerts a force on the tab and that force, which is inwardly directed, serves to lock together the two halves and ensures retention of the lens units within the lens cell.

  • Patent number: 6135669
    Abstract: A cylindrical shape with a open channel running the entire length (7). Opposite of the channel is a rib (5) added for strength and rigidity of the connector. Four openings (1) with a 45 degree angle (2) used for clearance open to four slots (3). Each slot is in line with another forming two groups which allow a flattened end of a rod to be inserted, lowered, and snapped in place. Inserting a rod into both groups creates a simple, economical, and reusable connection. Four tabs (4) protrude into the channel with a center line just above the top of the rod to be inserted allowing the rod to be held firmly in the connector and creating a barrier that doesn't permit the rod to start moving perpendicular to the connector which is how the rod is inserted and taken out. The length and width (6) of the material can vary depending on the weight requirements. A coated or inherently corrosion resistant alloy or a plastic that can resist the eliminates of the outdoors is appropriate.

  • Patent number: 5634733
    Abstract: The coupler has, in several embodiments, a compliant-link having flexible or pivoted fingers that engage a groove in the inside of a lower link in at least three places. The groove appears much like a bearing race. The compliant-link is retained inside of an upper sleeve that is attached to an upward-extending post. The lower (engaging) link is attached to a downward-extending post. The fingers are able to disengage from the groove under spring action and thus a sufficient applied moment will cause disengagement. Disengagement does not cause anything to break. Assembly, or reassembly, of the coupler may be performed without extra parts or tools. In several of the embodiments, the decoupling moment may be manually adjusted using less moment than the resultant decoupling moment. The decoupling moment is essentially independent of azimuth. The coupler is particularly suited to being used with rural type mailboxes, and warehouse buffers and supports.
