Abstract: A chair, including a flat seat bottom, having a surface area for accommodating a user; a base member having at least one protrusion, the protrusion being designed for traversing a perforation on the seat bottom, thereby joining the base member to the bottom of the seat bottom, and the base member being designed for supporting the weight of the seat bottom and the user; and a back support member, designed for being joined to the section of the protrusion located above the seat bottom, and for being leaned upon by the user. The base member is made of a single sheet, and is designed for being set into a predefined weight bearing configuration suitable for supporting the weight of the user. The base member is designed for being unfolded into a single layer sheet or folded into a multi layer sheet, following a disassembling of the chair. The chair is repeatedly assemblable and disassemblable.

Abstract: A hiking stick including a first section, which includes: a first shaft and a male joining piece attached to the shaft, and extending away from the shaft. The male joining piece has an uncut portion and a beveled portion. The bevel is formed by a plane cut at the end of the joining piece at an angle with a long the axis of the hiking stick. A second section includes a second shaft having a hollow end configured for receiving the male joining piece, such that an inner wall of the end of the second shaft has a radial cross section which is narrower than a radial cross section of the widest portion of the male joining piece. The male joining piece is configured for being inserted into the end of the second section, and for being radially compressed by the end of the second section.

Abstract: A convertible support apparatus for supporting an object over a ground surface is convertible between an operating configuration and a storage configuration. The support apparatus may comprise side members, a support area configured to connect to the side members, and a bow truss configured to bow. When the device is assembled in the operating configuration, both the support area and the bow truss are connected between the side members and the bow truss is configured to bow and place the support area under tension. The bow truss may comprise a bow tube connected between two foot fixtures. In one embodiment, when the apparatus is supporting a sufficiently heavy object, the bow tube will bow and contact the ground surface and provide additional support to the apparatus.
