Abstract: A buckle for use with infant seats and the like having a release button slideably mounted within a hollow buckle housing for simultaneously releasing a pair of male buckle members latched in the housing. A bottom bar is slideably mounted into the housing and provided with locking hooks received within openings provided in the housing for permanently locking the bottom bar to the housing. The bottom bar and male projection members are provided with openings for webbing belts. The housing has integral guide ribs for guiding the male members and bottom bar when inserted into the housing to ensure proper insertion and alignment in the housing. All of the members of the buckle assembly are preferably molded of a suitable plastic material.

Abstract: A swing drive mechanism for a swing having a swing seat, at least one hanger arm supporting the swing seat, and a pivot shaft providing reciprocal motion to the swing seat via the at least one hanger arm is described. The drive mechanism may include a gear, an eccentric element coupled to the gear and a motor mechanism configured to drive the gear. The drive mechanism may also include a substantially elongated drive link having a proximal end and a distal end, the proximal end coupled to the gear via the eccentric element, and a spring coupled to, and configured to being driven by, the distal end of the drive link. The spring being configured to directly drive the pivot shaft in a reciprocal fashion. A swing drive assembly including a blade and pivot shaft is also described.
