The disclosed technology relates to a building system for children that allows them to construct structures and playsets from hollow foam extrusions or foam logs that are stackable so they can make playsets of their own design or existing designs in which they can hide, play and let their imaginations soar. According to some embodiments, a log is a blown or expanded hollow circular extrusion of plastic. In some embodiments, the log is an elongated hollow cylinder with flattened exterior planar sections or substantially flat planar surfaces.


In some embodiments, the substantially flat planar surfaces are opposite one another. In some embodiments, the logs comprise apertures on two planar surfaces and at least one curved surface. In some embodiments the log comprises apertures at a minimum on the planar surfaces. These logs, in some embodiments, are straight, but by cutting and removing wedge shaped pieces from a log, the log can be easily bent into a predictable angle or curve. In some embodiments, the log is bilaterally symmetrical with two curved surfaces and two planar surfaces. In some embodiments the two flat surfaces have a hinge detail.


In some embodiments, an angled miter guide is used to cut two defined angled saw cuts to form a wedge in a log and then the wedge is removed from the log. In some embodiments, the removed wedge creates a wedge-shaped aperture which allows the log to bend to the same defined angle of the removed wedge. In some embodiments, the logs are bent into curves which allows for construction of toy playsets to be used in the building of a bow of a ship, a tower in a castle, or similar items.


In some embodiments, the construction toy playset may include injection molded fasteners. In some embodiments, the apertures of the log are configured for insertion of one end of the injection molded fasteners. In some embodiments, a string is passed through a portal of the injection molded fastener that protrudes from an outer surface of the log and the string is pulled tight such that the string and injection molded fasteners maintain the log in a predetermined, desired curved position. In some embodiments, adhesives, such as, but not limited to, hot melt, adhesive tape, packing tape or any combination thereof, maintain the log in the predetermined desired curved position. In some embodiments, removing multiple wedge shapes allows angles, curves and even full circles resembling a wheel to be formed with an originally straight log.


With reference now to the drawings, an exemplary angles miter device 30 is shown for cutting wedges at predetermined angle in a log of an exemplary construction toy playset. FIGS. 1 and 2 schematically illustrates the exemplary angled miter device 30 (hereinafter miter). In some embodiments, the exemplary miter 30 comprises at least two miter guides 31, a miter base 33 and guide supports 32. In some embodiments, the miter base 33 is configured to support a log 10 in position for cutting. In some embodiments, each miter guide 31 is U-shaped comprising two ends further comprising a first guide end and a second guide end. In some embodiments, the ends of each of the U-shaped guide are configured to be rotatably attached and adjacent to the miter base 33, and each U-shaped guide arches over the miter base, thus making each U-shaped guide operable to move in a plane between 0 to 90 degrees in relation to the miter base. In some embodiments, a log 10 of the exemplary construction toy playset is placed on the miter base 33 with the, at least two, miter guides 31 positioned such that toy saw blade 20 will cut the log at predetermined angles.


In some embodiments, each miter guide 31 guides a toy saw blade 20 such that the cuts converge from opposing directions assisted by the miter guides. Thus, the cuts of opposing direction form a wedge-shaped piece 15 configured to be removed from the log 10 creating a wedge-shaped aperture 15a. In some embodiments, the miter guides 31 are maintained in a predetermined position by guide supports 32. In some embodiments, an exemplary miter is made of plastic, metal, or any combination thereof.

The design grooves 34 used for support guides 32 may be for example, and not limited to, detents, channels, interference designs or any combination thereof. In some embodiments, the support guides maintain the angle of the meter guides by for example, and not limited to using, indents in the base operable to hold removable pegs, indents in the operable to hold fixed pegs, indents in the base to receive snaps, any method of pivoting, rotating, or sliding protrusions to anchor a miter guide to temporarily fix its position, or any combination thereof. FIGS. 4 through 7 are illustrations of different views for FIG. 3. In some embodiments, the guide supports each having a first guide support end and a second guide support end with the first guide support end configured to removably engage with a plurality of design grooves (not shown) in the miter guide and the second guide support end pivotably attached to the miter base (not shown) to maintain the at least one miter guide in a predetermined position.



FIG. 11 illustrates an exemplary miter 30, that in some embodiments is similar to the exemplary miter of FIG. 3. In some embodiments, the exemplary miter of FIG. 11 comprises support guides 32 that are configured, at a second end, to be pivotably attached to the miter base 33. In some embodiments, detail part 46 is configured to pivotally attach two parallel support guides to miter base 33. In some embodiments, the support guides further comprise a knob 47 extending from a first end of support guides 32. In some embodiments, the knob may be held in predetermined positions on miter guide 31 by engaging in one of a plurality of guide apertures 45 on the miter guide 31, thus supporting the miter guide in a predetermined position. In some embodiments, the knob and guide apertures may be any protrusion on a support guide and any aperture configured to receive that protrusion on the miter guide.



FIG. 8 illustrates an exemplary miter 30 of the current disclosure. In some embodiments, the ends of the miter guides 31 are pivotably connected to the miter base and further the ends of the miter guides comprise protrusion gears 34a that adjustably interconnect the two miter guides. In some embodiments, interference lock 32a is pivotably connected to the miter base and may be configured to lock the miter guides at a predetermined position by pivoting interference lock 32a to engage and stop the protrusion gears 34a from rotating. In some embodiments, cam locks are used to stop the protrusion gears 34a from rotating.



FIGS. 9 and 10, illustrate an exemplary miter 30, with a miter base 33 that comprises two channels 36 and each channel is on each of two lateral sides of the miter base. In some embodiments, the exemplary miter comprises a plurality of V-sections configured to form a V-section array 43 that comprises combination guides 31a and top connectors 41. The combination guides 31a are configured to both support another combination guide and be a guide for a saw thus providing both functions of 31 and 32 in FIG. 3.


In some embodiments, channels 36 receive one end of a plurality of pivot pins 35, 35a, and 38 that are configured to pivotably connect one combination guide to the miter base and/or two combination guides to each other and the miter base. In some embodiments, the pivot pins may be, but are not limited to plastic, metal, or any combination thereof. In some embodiments, the pivot pins are further configured to move laterally in channels 36. In some embodiments, each combination guide 31a is also pivotably attached with pivot pins to another combination guide and top connectors 41 and top connectors 41 are configured to support combination guides 31a that are parallel to each other on each lateral side of the miter base 33. In some embodiments, lockable pivot pins 35a and 38 lock the pivot pins at predetermined positions in the channel 36 and therefore maintain the V-section array in a predetermined position maintaining the angles in relation to the miter base 33. Thus, the V-section array is configured to be adjustable to desired predetermined angles in relation to the miter base 33. In some embodiments, the exemplary miter of FIGS. 9 and 10 further comprises raised indicators 49 configured to support guided placement of pivot pins 35, 35a and 38 in the channel.


In some embodiments, the exemplary construction toy playset, reduces the amount of plastic needed to build a conventional playset by 75 to 90 percent. In some embodiment, the exemplary construction toy playset reduces the amount of plastic needed to build a conventional playset by 85 percent. Using less plastic than conventional playsets is environmentally friendly. In some embodiments, all of the logs, fasteners, saws and miters are totally recyclable. In some embodiments, the construction toy playsets allow for inside, outside and water-play. In some embodiments, the construction toy playset withstands rain, wind and intense sunlight to the same degree as existing rotomolded conventional playsets because the logs are also made of the same polyethylene material that is used in the conventional rotomolded playset products. In some embodiments the construction toy playset allows users (children) to build their own designs with a soft material that can be cut, bent and fastened together to create a wide range of entertaining playsets. These playsets provide children not only excitement during the construction phase, but also a durable, imaginative educational toy to engage with after construction.
