Abstract: A toy, namely, an elastic band launcher is presented. The invention includes a launch section, two band bridges, a handle section, a trigger assembly, a bridge section, and an anchor. The launch section includes a first launch surface at a first acute angle with respect to a second launch surface. The band bridges are separately disposed along the first launch surface. The trigger assembly is interposed between and fixed to one end of the launch and handle sections. The bridge section includes a pair of opposed ends separately fixed to another end of the handle and launch sections. The anchor is fixed to the second launch surface. The anchor, launch surfaces, band bridges, and trigger assembly are adapted to receive an elastic band. At least one band bridge constrains separation between the sides of the elastic band. The elastic band disposed between the band bridges defines a main pull vector.

Abstract: An infant playpen includes a plurality of upright legs, and a first and a second upper side rail assembly supported by the upright legs. Each of the first and a second upper side rail assembly includes at least one elongated segment having an outer surface, and a plurality of positioning regions are defined on the outer surfaces of the elongated segments, each of the positioning regions being configured to locate a connection of a removable accessory on the infant playpen. An infant care system is also disclosed, which includes the infant playpen and a removable accessory installed thereon. One selected positioning region of the first upper side rail assembly can be received in a housing of the removable accessory, and a locking part of the removable accessory is displaced to a locked position that retains the selected positioning region in the housing.
