A foldable support frame assembly includes a row of support units arranged along a first direction. Each of the support units includes two support frames. Each of the support frames includes two parallel braces, a top rail connected fixedly between upper end portions of the linking rods, and a bottom rail connected fixedly between lower end portions of the braces. The braces of each of the support units constitute two first scissor-linkages spaced apart from each other along a second direction perpendicular to the first direction. The foldable support frame assembly further includes a plurality of second scissor-linkages arranged alternately with the support units along the first direction, and a positioning mechanism for maintaining each of the first and second scissor-linkages in an unfolded state.

A foldable supporting device includes parallel supporting frames and foldable units, each of which interconnects an adjacent pair of the supporting frames and includes a pair of crossing members that cross and that are pivoted to each other, and a joint mechanism having a pair of first joints and a pair of second joints that are connected respectively to the adjacent pair of the supporting frames. Each of the crossing members interconnects a respective one of two diagonally aligned pairs of the first and second joints. At least one of the pair of the first joints and the pair of the second joints interconnect upper and lower parts of the adjacent pair of the supporting frames, respectively.

An inflatable product includes an inflatable body having an exterior wall defining at least one air chamber therein, at least one electrical air pump unit, an electrical switch connected electrically to the electrical air pump unit, and at least one controller. The controller is operable manually to activate the electrical air pump unit so as to perform a selected one of inflation, full deflation, and partial deflation of the air chamber in the inflatable body.

An inflatable bed includes a bedstead assembly, a mattress assembly, and an electrical air pump unit. The mattress assembly is disposed on and above the bedstead assembly, and includes a top sheet, a bottom sheet disposed under the top sheet, and a plurality of surrounding sheets interconnecting the top and bottom sheets to form a plurality of air chambers, which are not in fluid communication with each other. Each of the air chambers is defined among the top sheet, the bottom sheet, and a respective one of the surrounding sheets. The electrical air pump unit is disposed on the bedstead assembly, and is operable to inflate the air chambers individually so that air pressures in the air chambers may be different.

Inflatable bed having air chambers inflatable individually by an electric air pump unit

An inflatable bed includes a bedstead assembly, a mattress assembly having at least one air chamber, and an electric air pump unit disposed on the bedstead assembly. The air pump unit includes a centrifugal pump device for performing initial inflation of the air chamber, a diaphragm pump device for performing subsequent inflation of the air chamber, and a control valve operable to allow for and interrupt fluid communication between the centrifugal pump device and the air chamber.

A bedstead assembly includes a support frame and a top plate unit disposed on the support frame. The support frame includes a rectangular foldable frame member convertible between unfolded and folded states. The foldable frame member includes a plurality of parallel non-foldable plates and a plurality of pairs of foldable plates. Any two adjacent non-foldable plates interconnect pivotally one corresponding pair of foldable plates to define a void space when the foldable frame member is in the unfolded state. The void spaces in the foldable frame member are arranged along a direction parallel to the foldable plates. Pivotable plate portions of the foldable plates are perpendicular to the non-foldable plates when the foldable frame member is in the unfolded state, and are parallel to the non-foldable plates when the foldable frame member is in the folded state.

A self-inflating mattress which comprises a first chamber, a second chamber, a foam and a check valve, wherein, the foam is disposed inside the first chamber. The check valve is provided between the first chamber and the second chamber, and air is allowed to flow only from the first chamber to the second chamber.

Self-inflating mattress

An air pump having a minimum number of parts. The air pump is built in the inflatable body of an inflatable product. The air pump consists essentially of a pump body, an air inlet provided on the pump body for introducing air outside the inflatable body into the pump body, and an air outlet also provided on the pump body for introducing the air from the pump body into the inflatable body.

Air pump having minimum number of parts

An air pump includes a first sheet, a second sheet, an inflation valve and a check valve. The second sheet is directly connected to the first sheet so as to form a chamber. The inflation valve is provided on the chamber to lead air into the chamber when the chamber is extended. The check valve is also provided on the chamber to discharge the air in the chamber when the chamber is compressed. The air pump can be built in an inflatable product.

Air pump of simple structure

By means of the interlocking methods skillful applying on the combination of the blanks, the supporting structures of the inflation products are easily constructed by these complementary blanks, and the same features of these products can be achieved by the economical usage of the sheet bars. Also, the strength of these products can be increased by the multiple supporting area of the interlocked blanks. This interlocking methods can be not only satisfied the all purposes of the inflation products but also met the standards of the environmental requirements because of its less scraps.

Interlocking method for manufacturing the inflation products

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.
