摘要： A multi-functional children's convertible furniture article which can be utilized for a number of different purposes including a bassinet, cradle, bench, desk, rocking bench, high chair, or changing table. The device includes a main frame h shaped member and two supported sides that are rotatable. The furniture article achieves all of its intended uses without disassembly. The main frame component is flat on one edge and curved on the opposite edge allowing for a rocking action in one disposition and stabilization when capsized. The main frame component allows for attachable legs to achieve its high position components. The rotatable sides have been designed to swivel up or down, singly or in unison. All of the furniture articles positions are achieved when combining one or more of the units actions.

摘要： A multi-purpose child support device comprises a frame having a base for placement on a floor surface and a support section positioned above said base. A seat element is configured for receiving a toddler child in a sitting position and is coupled with the support section above the floor surface for forming a high chair. The seat element is displaceably mounted to the frame and is operable for being selectively removed from the support section such that the support section receives an infant child carrier for supporting an infant child carrier above a floor surface.

摘要： A standing structure is formed by a plurality of poles and a holder movable between an open position and a closed position. In the closed position, the holder is dimensioned and configured to grip each of the plurality of poles and hold the poles in a standing structure. The poles form the legs of the structure. The holder is also configured to release the poles when moved to the open position to enable disassembly of the standing structure. A closure mechanism secures the holder in a closed position and a release mechanism releases the closure mechanism and thereby releases the poles from the holder. Accessories may be mounted on the standing structure. For example, with the holder attached to the midsection of the poles, a seat is mounted on the upper ends of the poles to form a stool. With the holder attached to the upper ends of the poles, accessories such as a camera mount, a table top, or a lantern may be attached to the holder to form various useful structures.

摘要： A slip resistant step stool includes a step surface with four legs extending downward. A slip resistant surface is bonded to the step surface. The slip resistant surface may be disposed in a pocket and have a ridge surrounding it. The slip resistant surface can be a thermoplastic elastomer. The stool can be manufactured by inserting the slip resistant surface in a mold adapted to form a step stool, then injecting molten resin into the mold, thereby bonding the resin to the slip resistant step stool.

摘要： A device convertible to present a child's highchair, booster chair, child carrier holder, rocking chair, and/or step stool or child's table has, generally, a chair with a back support, seat, and arms, a chair support assembly coupled to the seat, a tray assembly removably coupled to the chair arms, and a rocking assembly. The tray assembly is removably coupled, in a generally horizontal plane, to and above the chair arms to present a conventional highchair. The tray assembly is removably coupled, in a generally vertical plane, to the chair arms to present a child carrier holder. The tray assembly is removed entirely from the device to present a booster chair. The device may also have a chair support assembly having upper and lower leg assemblies removably coupled to each other, and a tray assembly having an inner tray removably coupled to an outer tray frame. In this way, the device is further convertible to a child's rocking chair by uncoupling the lower leg assemblies from the upper leg assemblies and removably coupling the rocking assembly to the upper leg assemblies, and to a step stool or child's table by removably coupling the lower leg assemblies to the inner tray.

摘要： A lightweight, portable sitting support for infants that provides back and side support for infants that can hold their heads up well and sit up for some amount of time unassisted but that do not yet have the skills to remain in a seated position without back and side support which is structurally sturdy and does not rely for stability on its own mass and weight or on the mass and weight or balance of the individual using it and which also has other applications during the child's infancy and as the child grows including as a lightweight, portable sleeping mat, chair and lounge chair. The base of the invention is a substantially rectangular-shaped, thinly padded base made of strong fabric such as nylon. Extending from the base are four cushions and four flaps with buckles. Two parallelepiped substantially rectangular-shaped cushions of the same width as the base extend horizontally over the base beginning at one of the base's horizontal edges and cover approximately two-thirds of the surface area of the base. At the opposite horizontal edge of the base, two parallelepiped substantially square cushions extend vertically at approximately right angles to the base. The seat of the invention is formed by the uncovered portion of the base lying between the two vertical cushions. Two flaps with buckles extend from the opposing longitudinal sides of the seat portion of the base. Two additional flaps with buckles extend from the opposing longitudinal sides of the base behind the lower of the two substantially rectangular-shaped cushions extending horizontally over the base. The invention also includes two parallelepiped unattached cushions of the same width and length as the seat. By buckling or unbuckling the flaps, changing the position of the invention, and/or placing the unattached cushion(s) in the seat, the invention variously forms the infant sitting support, infant and child sleeping mat, and child chair and lounge chair described.

摘要： Disclosed are a method and a system for predicting precipitation kinetics in precipitation-hardenable alloys, such as the 7000 series aluminum alloys, and for optimizing conditions for thermal treatment thereof. The method includes the steps of measuring a real-time temperature of an alloy component during the thermal treatment process, and using a signal in dependence upon the real-time temperature to predict, using executable code, a current state of the alloy component. The executable code includes a series of rate equations and initial parameters for a particular alloy. Optionally, the initial parameters for the particular alloy are provided after the code is in execution. The thermal treatment process is terminated when a predetermined state of the alloy component is predicted.
