Abstract: A portable shelter is erectable on a support surface for providing short to long term housing for humans. In general, the shelter includes a foundation, a floor supported by the foundation, and an enclosure. The shelter defines an interior which may be inhabited by a human. The shelter may include front, rear, side, and top walls, all of which may be folded to define inboard and outboard folds which enhance the structural integrity of the walls. The floor of the structure may include indentations corresponding to inboard folds of one or more walls for receiving the inboard folds for enhancing structural integrity of the shelter. The floor may be folded to form upstanding portions adjacent the indentations for securing the inboard folds in the indentations. Moreover, the walls may be folded to define feet which engage the support surface.

Abstract: A lightweight bed assembly kit includes slats and runners adapted for connection to each other at spaced apart locations to form a grid. A U-shaped channel member is adapted for connection to the grid to form a support frame. A covering constructed to form a substantially smooth sleeping surface for an adult human is sized and shaped to be disposed on a top surface of the support frame. A method of assembling a lightweight bed includes arranging runners and slats transversely to each other and connecting the runners and slats together to form a grid. A U-shaped channel member is connected to the grid to form a support frame. A covering constructed to form a substantially smooth sleeping surface is mounted on a top surface of the support frame. A second support frame can be connected to the first support frame by another U-shaped channel member.

Abstract: A telescopic chopstick including an upper section, a lower section and a press member. The upper section is a hollow rod formed with an upper opening and a lower opening. A locating section is formed on an inner side of the upper section. The lower section has an upper end and a lower end. The upper end has a peripheral length larger than a peripheral length of the lower end. The upper end of the lower section has a connecting section for engaging with the lower end of the upper section. The press member is fitted in the upper opening of the upper section and located by the locating section of the upper section. A leaf spring integrally extends from a bottom end of the press member. When the lower section is retracted into the upper section, the leaf spring resiliently abuts against and engages with a lateral wall of the connecting section of the lower section. The lower section can be easily taken out from the upper opening of the upper section for washing.

Abstract: A telescopic chopstick set including pair of chopsticks and a jacket for receiving the chopsticks. Each chopstick has an upper half and a lower half extendably nested in the upper half. An upper end of the upper half has an upper opening, while a lower end of the upper half has a lower opening. The lower half can be fitted into the upper half from the upper opening. A press member is fitted in the upper opening of the upper half. A pair of opposite first protuberances and a pair of opposite second protuberances are formed on inner wall face of the upper half near the upper opening. When the lower half is retracted into the upper half, the first protuberances abut against the lower half. The second protuberances serve to engage with and fix the press member with the upper half. A clip is disposed on outer side of upper section of the jacket for easy carriage of the telescopic chopstick set.
