摘要:
An apparatus and method for securing fiber optic cable to a connector, comprising providing a cable, said cable having an outer surface, an end section, a cable jacket, and a strengthening material; positioning a strain relief boot on said outer surface of said cable, said strain relief boot having an inner surface, wherein said inner surface has a first geometric pattern; providing a connector assembly, said connector assembly having a connector assembly part, a plug end, a cable end, and an exterior surface, wherein said exterior surface has a second geometric pattern which cooperates with said first geometric pattern on said inner surface of said strain relief boot, said connector part being located on said cable end; positioning said end section of said cable in a manner such that said cable jacket and said strengthening material touch, and cover said outer surface of said connector part; and using a simple tool to slide said strain relief boot toward said connector, and over said connector part, thereby exerting pressure and causing said cable jacket and said strengthening material to be captured in a hazardous path between said first geometric pattern on inner surface of said strain relief boot, and said second geometric pattern on said exterior surface of said connector assembly part.

A new and unique connector adapter shutter door assembly retrofitable to many existing connector adapters or receptacles which becomes a part of the same by connectedly fitting or snapping into place. The shutter door assembly can be used as a safety device to prevent laser light from escaping when a connector is removed from an adapter or receptacle. Because of the ease with which the shutter door assembly can be retrofitted to existing adapters, it is possible to selectively install the shutter door assembly only when a safety hazard is present. Also the shutter door assembly can be used to shield a connector end to prevent foreign matter, such as dust and dirt, from entering the connector. The shutter door assembly is a molded one-piece structure and has inwardly hinged doors permitting one hand connector insertion and withdrawal. The streamline design of the shutter door assembly takes very little space when in use making it desirable for typical space constrained applications.

A riding toy for children includes safety shields and end plates to prevent access to a set of longitudinal springs that provides a restoring force when the toy is "ridden." Also, the use of wide vertical struts that rotate about axes passing there-through near to a side thereof causes contact to occur between a strut corner and the base of the toy at the lower end thereof, and between a strut corner and the bottom of the riding structure at the top thereof, thus to provide a natural limit to the degree to which the riding structure can be thrust forward or backward, and thereby serving to prevent tipping the toy entirely over. Such a limitation of motion can also be obtained by contact of upper and lower corners of the safety shields and the riding structure or base, respectively, or between mutually facing sides of the struts on either or both sides of the riding toy. The structure thus provides a "ride" in which the seat upon which a child is placed remains horizontal at all times, no contact can be made between the child and the springs that provide the restoring force to the toy, and natural limits to the range of motion are provided that are approached smoothly, against the force of the springs, whereby the child can enjoy any pre-selected range of motion, in accordance with pre-selected dimensions of the toy components that may be implemented within a particular embodiment of the toy, without danger of being jolted off from the toy.
