A piece of inflatable sports equipment, preferably for water sports, is provided with a board (1) which can be inflated with a gaseous medium, preferably air, by means of a pump unit (6) having a compressor (7). The pump unit (6) is integrated together with the compressor (7) in the board (1) and preferably comprises assemblies (8, 9, 11) which drive the compressor and are installed together in a housing (12) which can be removed from and inserted into the board (1) and fastened therein. Inflation of the board can therefore be carried out anywhere and at any time during use of the board, since the means necessary for this are installed in the board itself.

The present invention is a connector for an inflatable member. A portion of the connector extends within an internal volume of the inflatable member to define a recess for accepting a structural connection. The connector has an air-impermeable surface that is configured to maintain integrity of the inflatable member to allow the internal volume to be pressurized when the connector is bonded to an opening in a surface of the inflatable member. The connector can optionally pass through the opposing surface or otherwise engage the opposing surface to enhance its structural properties.

The invention relates to a method for manufacturing volume element (10) which is inflatable with a gas, the method comprising the steps of: providing at least one first tube element (12) which comprises at least one first tube (1, 4) which is inflatable with the gas and is formed by at least two layers which are arranged one above the other, are formed from a per se limp material, and are connected with each other along at least one first seam (16d, 36); and providing at least one second tube element (14, 15) which comprises at least one second tube (5, 8) which is inflatable with the gas and is formed by at least two layers which are arranged one above the other, are formed from a per se limp material, and are connected with each other along at least one second seam (18d, 38), wherein the tube elements (12, 14) are provided in such a way that the seams (16d, 18d, 36, 38) are arranged on mutually facing sides of the tube elements (12, 14) and have, at least in respective length portions (40), curvatures that are different from each other.

Pressurized air apparatuses and associated methods are described. According to one aspect, a pressurized air apparatus includes an air input configured to receive pressurized air, a pressure sensor configured to receive the pressurized air from the air input, measure a plurality of different pressures of the pressurized air at a plurality of moments in time, and generate a plurality of signals that are indicative of the different pressures of the pressurized air, processing circuitry configured to receive the signals from the pressure sensor, and process the signals to select one of the signals and disregard others of the signals, and a user interface configured to communicate a value indicative of the pressure of the pressurized air that corresponds to the selected one of the signals to an operator of the pressurized air apparatus.

An inflatable product is provided, including a first wall, a second wall, and a plurality of internal tensioning members connecting the first and second walls. Each internal tensioning member includes a first fixing strip and a second fixing strip respectively coupled to the first wall and the second wall. The inflatable product further includes a thread helically wound around the first fixing strip and the second fixing strip. First parts the thread are fixed between the first fixing strip and the first wall, and second parts of the thread are fixed between the second fixing strip and the second wall. An apparatus set and method for manufacturing the inflatable product are also provided.

An inflatable flotation chamber comprising a seamlessly constructed flexible tube, sealed ends, and a valve for inflation and deflation. Said chamber characterized in that it can be inflated to a relatively high pressure, giving functional shape and independent structural rigidness to the chamber.

A watercraft characterized by one or a multitude of such inflatable flotation chambers. A method of constructing such an inflatable flotation chamber.

A stand-up paddleboard (SUP) may be configured with a non-retentive binding system to secure a user's foot positioning. In one example, the binding system may include pockets formed from panels extending continuously along edges of the paddleboard, and straps to provide tension on the pockets, to reduce a likelihood of undesired sliding of the user's feet. The pockets of the binding system may allow the user to reposition the user's feet to multiple secured footholds within the binding system, thereby allowing the user's stance and balance to be maintained.

An inflatable stand up board, comprising: a top layer having a first perimeter; a bottom layer having a second perimeter; a drop stitch layer disposed between the top layer and the bottom layer; a first sealing sheet coupled in an airtight configuration to the first perimeter and the second perimeter; a second sealing sheet disposed at least at one of a front end or a tail end of the inflatable stand up board. The second sealing sheet is coupled in an airtight configuration to the first and second perimeters, and overlaps at least part of the first sealing sheet. The top layer, the bottom layer and the first sealing sheet define an inflatable chamber of the inflatable stand up board. The side of the inflatable stand up board is not easily broken and a double sealing effect is achieved, preventing air leakage.

A double-chamber inflatable paddle board with detachable function includes an outer chamber, an inner chamber and a fixing connector strip. The outer and inner chambers are independent chambers. A middle portion of the outer chamber includes an opening with an accommodating cavity that matches the inner chamber. One side of the fixing connector strip is fixedly connected to one of an inner edge of the outer chamber and an outer edge of the inner chamber, and the other side is suspended. In an inflated state, the other side of the fixing connector strip is engaged on one of the outer edge of the inner chamber and the inner edge of the outer chamber, to cooperate with the connected chamber to form an inflatable paddle board product with flat surface. The inner and outer chambers are detachably connected into one piece through the fixing connector strip.
