Abstract: The device comprises a plate (1) whose top face (10) constitutes a writing surface, said plate being elevated above the support surface (S) on which the device stands by means of an underframe (2). One of the edges of the plate is provided with at least one ring (3) for holding sheets onto the plate, the ring interconnecting the two faces of the plate (1) in such a manner that the sheets can be passed beneath the plate by rotating them through 360.degree. around the ring (3). The device is provided with fastening and retaining means (5) for engaging the sheets (F.sub.2) beneath the plate (1) at a certain distance (K) above the support face (S).

Abstract: A wheeled device for carrying sail boards comprises a support on which the sail board float is set and a fast coupling system for receiving the said board mast. The fast coupling system has two couplers in which the mast is set. Once the sail board mast has been secured to the couplers, the wheeled device is positioned with its front end resting on the ground or in a trailer position on the wheeled device. The axle of the wheels is located far enough back for gravity to jam the mast between the couplers.
