Abstract: A holding structure and a vehicle sunshade used thereof includes a seat and a bonding member. The seat includes a body, a clamp portion connected to the body and an extended portion connected to the body and extended in a direction remote from the clamp portion. The body has a first connection plane faced the extended portion. The extended portion has a second connection plane faced the body. The bonding member is bonded to the first connection plane and the second connection plane, and includes a first bonding surface corresponding to the first connection plane and a second bonding surface corresponding to the second connection plane. The invention can hold the vehicle sunshade on a vehicle window frame and provide firmer bonding of the vehicle sunshade to the vehicle window frame through the two bonding surfaces.

Abstract: A tensioning device is described for a carrying net (6), in particular between the hulls (1) of a catamaran, the carrying net (6) being fastened in a tensile-resistant manner to two mutually opposing legs of a tensioning frame. In order to attain advantageous tensioning conditions, it is proposed that one of the two legs be mounted, as the tensioning leg (5), in the tensioning frame so as to be rotatable about a pivot shaft (10) which is parallel to its longitudinal axis, the pivot shaft extending, when the carrying net (6) is tensioned, on the net side at a distance from the run-off line (13) of the carrying net (6) from the tensioning leg (5), and that an interlocking means (15) be provided for the tensioning position of the tensioning leg (5).

Abstract: A simple, lightweight, manually-controlled device for stabilizing and increasing the performance of small, sail-assisted watercraft, containing a single moving part and comprising a curved spar or iako (1) joining a main hull and a single outrigger hull or ama, a tubular shaft (2) with a handle (7) at one end and an “L” shaped hydrofoil (5 and 6) at the other end. The tubular shaft (2) is joined to the iako (1) by two or more struts (3) that are fixed to the iako (1) at their upper ends and have machine screws (8) or sleeves (4) at their lower ends by means of which the tubular shaft (2) is permitted to rotate around its longitudinal axis and is prevented from moving horizontally in relation to the curved iako (1), thereby making the entire assembly a truss or girder that resists vertical distortion or flexion.
