초록 ▼

The invention relates to a method of producing an air mattress, which comprises a pump part and a part, which is to be pumped up. A propellant is disposed in the pump part and the wall, which separates the pump part from the part, which is to be pumped up, has a one-way valve and a small opening, through which air can flow back from the part, which is to be pumped up, into the pump part. An inlet opening is disposed in the pump part and an outlet opening is disposed in the part, which is to be pumped up. Pursuant to the invention, a metallic tool is used for welding the pump part wall between the upper and lower covering skins of the air mattress. The tool forms one part of a high-frequency welding machine, having two plates, which lie against the outside of the covering skins. The tool is removed before the edge seals of the air mattress are produced. When the pump part is disposed within the air mattress, a dividable tool is used.

대표청구항 ▼

[ I claim:] [1.] A method of producing an air mattress having a pump and an inflatable part, wherein the pump has an inlet opening, which can be closed off, and the pump is connected to the inflatable part by a one-way outlet valve, the pump has a propellant material for biasing the pump into an expanded state and said inflatable part has an outlet opening for deflation, the method comprising the steps of:forming upper and lower covering skins of the air mattress from thermoplastic material;forming a pump wall of said pump part from thermoplastic material, the pump wall having opposite sides with web lugs extending from an exterior surface of said pump wall;disposing said upper and lower covering skins parallel to one another and between an upper and a lower plate of a high frequency welding machine;providing a metallic sealing die tool having die walls conforming to at least a portion of an outside perimeter of an installed state of said pump wall and extending substantially perpendicularly with respect to said upper and lower covering skins, the sealing die tool being divided into first and second die parts which are connectable together to encircle said pump and having slots for accepting said web lugs, said slots communicating with connectable edges of said first and second die parts;disposing said pump wall over an inside surface of said die walls with upper and lower edges of said pump wall being folded over upper and lower surfaces of said die walls and inserting said web lugs through said slots in the sealing die tool;interposing said sealing die tool with said pump wall disposed thereon between the upper covering skin and the lower covering skin;pressing the upper and lower plates together to clamp said upper and lower edges of said pump wall in contact with said upper and lower covering skins;applying a high frequency power source to said upper and lower plates to weld said upper and lower edges of said pump wall to the upper covering skin and the lower covering skin, respectively;separating said first and second die parts and removing said sealing die tool from between said upper and lower covering skins after the welding process; andjoining said web lugs in diagonal directions to the upper covering skin and to the lower covering skin.
