Abstract: Inflatable articles of clothing are disclosed. Using in many cases multiple plies of material impervious to air, inflatable pockets are created. Valves may also be included to facilitate introducing air into the pockets and, if necessary, to permit their deflation.

Abstract: Disclosed is an inflatable sofa which can be quickly inflated for use or deflated for convenient storage and transporting. At least one recess is formed in a seat portion of the inflatable sofa for accommodating heat-absorbing material to make the sofa more comfortable for sitting. Containers with accordion bodies for holding cups or cans are connected to armrest portions of the inflatable sofa by radio heating and form an integral part of the inflatable sofa.

Abstract: Disclosed is an inflatable leisure chair which can be quickly inflated to serve as a comfortable sofa for use indoors and/or outdoors. A plurality of I-shaped supporting beams made of plastic material of high tensile strength are radio heated to and between inner surfaces of a seat and a bottom of the inflatable chair to reinforce the space in the inflatable chair below the seat. The inflatable leisure chair can be quickly inflated for use and deflated for convenient storage and carrying.

Abstract: Open pool forming a reservoir for liquid, especially swimming pool, of the out-of-ground type with a flexible wall (2) and an inflatable tubular chamber (3) constituting a floating ring which defines the opening of the pool, characterized in that, in the service position of the pool (1), the upper peripheral region (5) of the flexible wall (2) adjoining the tubular chamber (3) is inclined, relative to the remaining underlying part of the wall, towards the inside of the pool, by virtue of which the upper peripheral region (5) forms a frustoconical reentrant rim underlying the tubular chamber (3) and capable of holding the tubular chamber (3) up when the latter is subjected to a downwards force.

Abstract: A valve for controlling the flow of a fluid, in particular a liquid, said valve comprising a closure member (1) of compact shape which is resiliently deformable, at least superficially, and which is suitable for closing or exposing a fluid flow orifice (2) which opens out at a surface (3) of the valve body (4), the surface (3) of the valve body (4) is generally plane and the closure member (1) is mounted to rotate freely about an axis (5), on support means (6) which are constructed so that, when the valve is closed, the closure member (1) approaches the orifice (2) with zero or a relatively small incidence with respect to the plane surface (3) so that, at least at the end of the approach, the closure member (1) rolls on the plane surface (3) and is resiliently compressed against that surface until it covers the orifice (2) which it then closes sealingly, the support means also being constructed so that, when the valve is open, the closure member (1) is held away from the orifice (2) and is not compressed agai

Abstract: Disclosed is an inflatable water toy, which includes an elongate tubular body. An aperture is provided through a first end of the tubular body, and the aperture is dimensioned to slidably receive the second end of the tubular body therethrough. Advancing the second end of the tubular body through the aperture forms a continuous loop, which may be continuously adjusted such as by cinching to adjust the loop to any of a wide variety of loop diameters, such as for positioning about the waist of a user.

Abstract: A submersible swimming pool cleaner including a wheeled housing into which an intake fitting for the intake of pressurized water is disposed, and an angularly disposed manifold member inside of the housing containing a plurality of apertures through which the pressurized water is directed at an angle against the pool bottom. A pair of wheel members are positioned at a front of the housing to facilitate transport of the apparatus across the pool bottom and to provide a clearance between the leading edge of the housing and the pool bottom through which debris may enter into a cavity of the housing. The housing further includes a wiper blade secured to the housing rearwardly of the manifold and positioned to seal and direct water along the pool bottom when the apparatus is in operation and thereby further loosen debris from the pool bottom. A debris collection bag is fixed over an exhaust aperture in the rear of the housing for collecting debris.

Abstract: This annular inflatable element comprises two ring-shaped elements interconnected by an inner closed belt and an outer closed belt. All these elements are welded together, and all the welds are of the sleeve coupling type without requiring any complementary or additional welding operation. The last sleeve-coupling weld is formed by placing the outer belt against the inner surface of the annular electrode, and the belt lips are folded firstly outwardly and then inwardly between the electrode and registering contra-electrodes. Paper welding barrier are interposed between the first and second folded portions of the belt lips, and the lips of the ring-shaped elements are placed against the contra-electrodes, respectively, so that the last two sleeve-coupling welds can be accomplished simultaneously. This invention is applicable notably to the manufacture of rubber dinghies.

Abstract: This inflatable boat comprising at least one hull consisting of at least first and second elements disposed side by side, inflatable separately, and one or a plurality of additional elements inflatable separately and adapted to support one or a plurality of relatively heavy members to be secured to the hull, in case the first inflatable element becomes inoperative. Preferably, the additional element is included in the volume of the first element and in the upper portion thereof, in the vicinity of the wall of the second element, so that when the first element becomes inoperative the second element can support the additional inflatable element and the heavy member is kept in a fixed position. This heavy member may consist for example of an outboard motor or a sail mast supporting structure.

Abstract: A rowlock fitting for inflatable boats made as a unitary whole having a sole with a peripheral flange for adherence to the boat. Two upstanding, rigid, reinforcing ribs centrally located on a same side of the sole and integral therewith and made of a same material reinforce the central portion of the rowlock fitting and preclude transfer of twisting forces to the boat by the oars when in use. The ribs intersect substantially normal to each other. A rigid socket for an oarlock is disposed at a region of intersection of the ribs and is encircled by this region. The rigid ribs extend radially from the socket.

Abstract: This sail mast supporting brace structure of Y or T configuration is intended for a single-hull boat and comprises three arms adapted to be secured one to the bow and the other two to the lateral portions of an inflatable hull; the side arms are adapted to cooperate with telesopic elements engaging the holes of rowlocks carried by said lateral portions. The arrangement is such that the boat can easily be operated with or without sails, without having to deflate the hull.
