Systems and kits for assembling and/or modifying a blanket-based structure are disclosed. An exemplary system includes an enclosure element having one or more attachment mechanisms fixedly attached to the enclosure element and configured to detachably associate with one or more environmental structures. The exemplary system additionally includes a plurality of connection features, a plurality of complementary connection, and a plurality of eyelets disposed along the perimeter of the enclosure element. The exemplary system additionally includes one or more weights selectively attachable to the enclosure element at one or more of: the attachment mechanisms, the plurality of connection features, the plurality of complementary connection features, the plurality of eyelets, or combinations thereof.

A prefabricated interlocking building block is used in the construction of structures. The block is composed of a material comprising polyvinyl chloride and is substantially hollow, with a density of not more than 10 lbs. per cubic foot.

Paper-based elongate structures suitable for use as lumber substitutes, articles of manufacture made thereof, kits of materials including such structures, and machines and methods for making the same. Elongate structures according to the invention include a hollow outer portion formed of corrugated fiberboard sheet material and an accordion-folded inner support formed of corrugated fiberboard sheet material. The hollow outer portion has four outer surfaces that define a rectangle when viewed in cross-section transverse to a longitudinal axis of the elongate structure. The accordion-folded inner support is enclosed within the hollow outer portion. The inner support includes a plurality of first spaced-apart peaks that contact a first inner surface of the hollow outer portion and a plurality of second spaced-apart peaks that contact an opposing second inner surface of the hollow outer portion. The accordion-folded inner support structure improves the beam strength, crush resistance and lateral strength of the elongate structure.

Provided are a play activity tracking system and a play activity tracking method. When a child walks around each of a plurality of sensory play spaces and performs a play activity excitingly while wearing a beacon device, individual play patterns are monitored and collected through beacon devices, and the collected data is analyzed in real time according to various indicators to print out a comprehensive play result on a report result sheet. The play activity tracking system includes: at least one beacon device worn on a body of a user who walks around a plurality of play spaces and performs a play activity; a user registration device for registering the user; at least one beacon scanner disposed at each of the play spaces; a data collection and analysis device for collecting data of the beacon scanner; and a play report device communicating with the data collection and analysis device.

The present invention relates to a unit block having a coupling portion and an insertion portion provided in special structure and shape such that, instead of providing an assembly-type toy that makes a user build an assembly-type completed product according to the manual, the user is enabled to implement various articles by exercising creativity without feeling bored. The present invention provides a unit block, which has integrally provided coupling and insertion portions, and provides, as a means for using the same when a desired object is to be implemented.

A play mat assembly includes a mat with a first major surface and an opposing second major surface and a plurality of extension coupling points on the first major surface. An extension having a proximal end is removably coupled with one of the plurality of extension coupling points. The extension extends away from the proximal end at the first major surface of the mat to a distal play piece connection point. A play piece is removably coupled with the play piece connection point.
