Abstract: An air mattress includes an upper sheet with a tufted top surface, a lower sheet, and front and rear sheets. The front sheet has upper, lower and lateral edges. The upper edge of the front sheet is sealed to a front edge of the upper sheet, is longer than the front edge of the upper sheet, and has excess portions on two sides of the front edge of the upper sheet. The rear sheet has upper edge, lower and lateral edges. The upper edge of the rear sheet is sealed to a rear edge of the upper sheet, is longer than the rear edge of the upper sheet, and has excess portions on two sides of the rear edge of the upper sheet. The lower sheet has a front edge sealed to the lower edge, the lateral edges, and the excess portions of the upper edge of the front sheet. The lower sheet has a rear edge sealed to the lower edge, the lateral edges, and the excess portions of the upper edge of the rear sheet. The lower sheet further has lateral edges sealed to lateral edges of the upper sheet.

Abstract: An air pump comprises a hollow pump body, at least one pulling member, an air inlet and an air outlet. The hollow pump body has air inside and consists of flexible sides and two opposite stiff ends. The air outlet is provided on the pump body to discharge the air in the pump body when the pump body is pressed. The pulling member is attached to one of the stiff ends of the pump body in order to restore the pressed pump body by pulling the pulling member. The air inlet is provided on the pump body to suck outside air into the pump body when the stiff end is pulled by the pulling member to restore the shape of the pressed pump body.

Abstract: An inflatable boat comprises an inflatable body, at least one inflatable wing member and at least one holding device. The inflatable wing member is attached onto the inflatable body, while the holding device is connected to the inflatable wing member. Furthermore, the inflatable wing member has a rowing plate on which at least one check valve is provided. The inflatable boat can go ahead on a surface of water when the inflatable wing member is pulled by the holding device to paddle the water.

Abstract: An inflatable article for a person to rest thereupon and which is capable of generating massage bubbles for the person when the inflatable article is immersed in water. The inflatable article is composed of at least three layers of PVC sheets which include a first layer of PVC sheet, a second layer of PVC sheet, and a third layer of PVC sheet. The first layer and the second layer are heat-sealed together at a plurality of upper joints so as to form at least one inflatable air chambers between the first layer and the second layer, with a plurality of upper and lower vent holes being, respectively, formed in those areas of the heat-bonded first layer and second layer other than the air chamber so as to communicate the water around the inflatable article with the region below the second layer.

Abstract: A floating hammock for a user to rest thereupon on the water of a swimming pool. The floating hammock comprises a sling for the user to lie his/her body thereupon; a headrest for the user to rest his/her head thereupon; a footrest for the user to rest his/her feet thereupon; and a pair of armrests for the user to rest his/her arms and hands thereupon. The headrest, the footrest, and the armrest are either inflatable or made of foam such that the floating hammock is capable of floating above the water. The user resting upon the floating hammock can immerse himself/herself further into the water by adjusting either the length of the armrests or that of the sling.

Abstract: An auxiliary package for a bath-pool, particularly for a sauna bath-pool, comprising a housing having a water inlet for receiving water from the bath-pool, a water exit for sending the water back to the bath-pool and a plurality of partition walls for dividing the interior of the housing into a plurality of chambers and forming a water passage therein, a water pump mounted in one of the chambers for sucking the water from the inlet and circulating the water through the passage to the bath-pool, an electric motor mounted in one of the chambers for driving the water pump capable of transfering the heat generated to the water flowing in the passage, a control box for controlling the electric motor, which is mounted watertight on the housing, and electric plug means adapted for connection to a power system for receiving electrical power.

Abstract: Disclosed is a mounting structure of a propulsion device for an inflatable boat, including a propulsion assembly, which comprises a power device and a driven propeller; a sleeve body, whose internal diameter is larger than the longitudinal length of the propeller of the propulsion assembly so as to allow the easy passage of the propeller of the propulsion device through the sleeve body; a mounting hole securely devised in the hull, the hole being provided near the stern of the inflatable boat in accordance with the habitual practice as well as for convenience sake, and the internal diameter being larger than the external diameter of the sleeve body; a power device supporting element, which is secured to the sleeve body so that when the propeller of the propulsion assembly passes through the sleeve body it can maintain the power device of the propulsion assembly above the flange of the cover of the sleeve body; and a set of direction control levers to turn the propeller of the propulsion assembly so as to cont

Abstract: An air pump for inflating an inflatable article includes a multi-stage centrifugal compressing section for inhaling and compressing primary air and a secondary air inhaling mechanism provided downstream of the multi-stage centrifugal compressing section. At the beginning of the inflation operation, extra secondary air can be rapidly inhaled into the air pump and delivered into the inflatable article mainly by means of the secondary air inhaling mechanism and thereafter, when the inner pressure of the inflatable article gradually increases to exceed the predetermined level, the secondary air inhaling mechanism may be closed so that only the multi-stage centrifugal compressing section for primary air functions to continue the subsequent inflation operation in a higher pressure range. Thus, an ideal and speedy inflation operation may be achieved without reducing the inflation pressure.

Abstract: An inflatable suntanner comprising an upper transparent layer, a middle reflective layer and a bottom layer which are all made of flexible, gas impervious material. The middle layer is bonded to the upper layer at a plurality of upper joints and to the bottom layer at a plurality of lower joints, with the area or size of each upper joint being different from that of each lower joint so as to corrugate those portions of the middle reflective layer interconnecting the upper and lower joints. Accordingly, sunlight passing through the upper transparent layer and incident on the corrugated reflective layer is both evenly and irregularly reflected upon the side not exposed to the sun rays, of a user on the suntainner so as to expedite a homogeneous suntan.
