DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In one embodiment of the present invention, a pump 100, FIGS. 1 and 2, is provided. The pump 100 is designed to create a high volume, low pressure pump that is hand operated, lightweight, very small packing, and that does not require the use of electricity. The pump features an inflatable chamber portion also termed an inner bag 102. The inflatable chamber portion or inner bag 102 includes an upper inflatable portion 104, a lower inflatable portion 106 and an inflatable structure or architecture comprised of a plurality of inflatable support portions 108. The plurality of inflatable support portions 108 serve essentially as a return spring to expand or return the pump to its original shape after its compression and serve to keep the upper inflatable portion 104 and lower inflatable portion 106 connected, but separate from one another and urging air back into the inflatable chamber portion or inner bag 102. The inflatable chamber portion 102 is a singular air chamber that includes the upper inflatable portion 104, which is connected to the lower inflatable portion 106 via the plurality of inflatable support portions 108.
The upper inflatable portion 104 is connected to a top surface 118 at an outer edge 122. The top surface 118 has an upper face 128 and a lower face 130. The lower inflatable portion 106 is connected to a bottom surface 120 at an outer edge 124. The bottom surface 120 has an upper face 132 and a lower face 134. The inflatable support portions 108 our inflated by a user's mouth via an air inlet device 110. The air inlet device 110 can be located anywhere in the inflatable support portions 108 (which are coupled to one another as a single air chamber), and is preferably located on an exterior surface 136 of the inflatable support portions 108. A user can blow air into the air inlet device 110 thereby inflating the inflatable support portions or structure 108. Once the inflatable support portions 108 are inflated, the pump exhibits a semi-rigid shape.
An inner bag 114 is connected to the lower face 130 of the top surface 118 and the upper face 132 of the bottom surface 120. The top surface 118 further features an opening 116, preferably located in the center of the top surface. The opening 116 provides access to an interior 138 of the inner bag 114 allowing a air to enter into the inner bag 114 as shown by arrow 150. The inner bag 114 further features an air outlet device 112. The air outlet device 112 is preferably a one-way valve and may feature connection means 126, such as ribs or teeth that help grasp a nozzle of a device to be inflated (not shown). The air outlet device or valve 112 is preferably welded into a lower portion of the inner bag 114 of the pump 100 but may be located anywhere on the exterior surface of the inner bag.
The pump functions by a user placing their palm at least partially over the opening 116 (thereby preventing air from escaping from the opening 116) and pressing the pump 100 downward, such that the top surface 118 is pressed towards the bottom surface 120 and the plurality of inflatable support portions 108 at least partially compress. As a user presses the pump downward, air located within the interior 138 of the inner bag 114 exits the inner bag 114 through the attachment valve (air outlet) 112 as shown by arrow 125. After the pump is compressed downward, the user raises their hand at least slightly away from the top surface 118 and the plurality of now compressed inflatable support portions 108 of the pump 100 act as return springs, causing the pump 100 to rebound to its starting position while the opening 116 allows air to enter and fill the interior 138 of the inner bag 114 readying the pump 100 for another compression. The one-way valve mechanism 127 of the attachment valve 112 prevents air from traveling back into the pump as the pump rebounds and air refills the pump through opening 116. The pump 100 can be repetitively and rapidly compressed and allowed to return to the starting position in order to inflate an inflatable device (not shown) connected to the attachment valve 112.
The pump 100 is preferably made from a plastic and/or fabric material that is sewn and/or welded, thereby making the pump 100 air and water tight and very lightweight. After a user is finished inflating their inflatable device, the user can open the air inlet device 110 and allow the air held within the inflatable chamber portion 102 to exit. When the air has been removed from the inflatable chamber portion, the pump can be compressed, folded or rolled into a very small size and stored. The packed size of the pump amounts to the size of the inlet device 110 and attachment valve 112 plus the small amount of fabric or plastic film used to make the pump.
Accordingly, the present invention provides a novel lightweight inflatable air pump. Modifications and substitutions by one of ordinary skill in the art are considered to be within the scope of the present invention, which is not to be limited except by the allowed claims and their legal equivalents.
