DETAILED DESCRIPTION OF THE INVENTION
[0014] Fig. 1a and Fig. 1 b are perspective views of a hand-actuated pump 100 in an extended position. The hand-actuated pump 100 includes a cylinder 105 and a piston 107 configured to be fully inserted into the cylinder 105, as shown in Fig. 2 The repetitive insertion and removal of the piston 107 enables the inflation of an inflatable object, such as a flexible inflatable support. The cylinder 105 and piston 107 are generally cylindrical in shape and define an inner chamber. However, other geometries may be utilized. The cylinder 105 and piston 107 may comprise any material suitable to enable pumping operations, such as plastic, metal, or a different material. [0015] The distal end 107a of the piston 107 defines a handle 125 that enables pulling the piston 107 out of the cylinder 105. A pair of valves 400 enabling air to be drawn into the pump 100 are positioned at the distal end 107a of the piston 107. The number of valves 400 may be increased or decreased depending on the amount of air flow desired. The valves 400 are described in more detail below.
[0016] The inside diameter of the cylinder 105 and the outside diameter of the piston 107 are sized to allow the piston 107 to slide inside the cylinder 105 and to form a substantially air tight seal between the piston 107 and the cylinder 105. In some implementations, the piston 107 may define a raised annular ridge, hereinafter referred to as a ring 310, on the outside surface towards the proximal end of the piston, as shown in Fig. 3a. The ring 310 may further improve the seal between the piston 107 and cylinder 105.
[0017] Returning to Fig. 1 , the cylinder 105 may define one or more raised annular ridges, hereinafter referred to as rumble strips 112, at the distal end 105b. The rumble strips 112 are configured to engage the ring 310 (Fig. 3) defined on the piston 107. The rumble strips 112 and ring 310 cooperate to produce noise when the ring 310 is drawn across the rumble strips 112. The noise in turn warns an operator that the piston 107 is near the end of its operative position. The number of rumble strips 112 may be increased or decreased to increase or decrease the intensity of the warning provided to the operator.
[0018] The cylinder 105 may define a raised annular ridge 114 at the distal end 105b with an interior surface (not shown) configured to engage the ring 310 and generally prevent the piston 107 from being completely removed from the cylinder 105 during pumping operations.
[0019] The proximal end 105a of the cylinder 105 defines an exhaust port 115. The exhaust port 115 enables attachment of the hand-actuated pump to an inflatable object such as an air mattress. The exhaust port 115 is utilized to communicate air to the inflatable object and may be integrally formed with the cylinder 105 or may be removably attached. For example, the exhaust port 115 may be glued, welded, or screwed to the cylinder 105.
[0020] Figs. 3a and 3b are cross-sectional views of the exhaust port 115 (Fig. 1 b). The exhaust port 115 includes a coupler 300 and a cover 315. In some implementations, the coupler is generally cylindrical and is configured to move within an opening defined in the proximal end 105a of the cylinder 105.
[0021] The coupler 300 may include locking members 305 that enable removable attachment of the hand-actuated pump 100 to an inflatable support. For example, the hand-actuated pump 100 may be locked to the inflatable object by sliding the coupler inside a complementary port (not shown) on the inflatable object. The coupler 300 may then be rotated so that the locking members 305 engage complementary locking members (not shown) on the inflatable object. The hand-actuated pump 100 may be removed by reversing the direction of rotation of the coupler 300. Locking the hand-actuated pump 100 to the inflatable object enables an operator to concentrate his efforts on filling the inflatable object with air rather than trying to forcibly keep the hand-actuated pump 100 and inflatable object together.
[0022] The cover 315 is configured to be inserted into an opening of the coupler and may prevent objects from entering the hand-actuated pump when not in use. The cover 315 includes a tail 315a configured to be inserted into the retention tab 320 located on the proximal end 105a of the cylinder 105. The retention tab 320 defines an opening for receiving the tail 315a of the cover 315.
[0023] Fig. 4a and Fig. 4b are front and back views, respectively, of the valves 400. The valves 400 enable unidirectional flow of air into the piston during pumping operations. When the piston and cylinder are pulled apart, the valves 400 allow air to enter the inner chamber defined by the piston 107 and cylinder 105. When the piston 107 and cylinder 105 are pushed together, the valves 400 close. This forces air through the exhaust port 115. In one implementation, two valves are utilized. However, the number of valves may be increased to increase air flow into the chamber or decreased to save space and reduce costs. Placement of the valves on the distal end of the piston provides for the decreased resistance of air flowing into the hand-actuated pump when the piston is drawn out of the cylinder. This in turn leads to reduced fatigue on the part of the operator.
[0024] Each valve 400 includes a valve membrane 405, a bridge support 410, and a valve grill 415. The bridge support 410 is utilized to secure the valve membrane 405 over an opening in the distal end 107a of the piston 107. In some implementations, the valve membrane 405 is circular and has a diameter that is approximately the same size as the diameter of the opening. However, the shape of the valve membrane 405 may be adapted to cover a valve opening with a different shape. The valve membrane 405 may comprise any material suitably flexible, yet impermeable to air flow, such as rubber, to allow unidirectional flow of air.
[0025] The valve grill 415 is configured to prevent objects that may obstruct air flow and/or damage the chamber defined by the cylinder 105 and piston 107 from entering through the valve. In some implementations, the valve grill includes tabs or snaps 415a which enable removable attachment of the grill to the distal end 107a of the piston 107.
[0026] Fig. 5a and Fig. 5b show an unpacking operation of the hand-actuated pump 100. An inflatable object 500 may be stored in the hand-actuated pump 100. To remove the inflatable object 500, the operator may remove the piston 107 from the cylinder 105 as shown in Fig. 5b. The inflatable object 500 may then be removed from the piston 107.
[0027] Fig. 6a - Fig. 6c illustrate a pumping operation of the hand-actuated pump 100. In Fig. 6a, the operator may attach the coupler 300 (Fig. 3b) at the exhaust port 115 (Fig. 1 ) of the hand-actuated pump to a complementary coupler (not shown) on the inflatable object 500. The operator may then lock the hand- actuated pump 100 to the inflatable object 500 by rotating the coupler 300 until the locking members 305 (Fig. 3) engage a set of complementary locking members (not shown) on the coupler of the inflatable object 500. [0028] As shown in Fig. 6b, the operator may then place his hand through the handle 125 and initiate pumping operations to inflate the inflatable object 500. During pumping, should the ring on the piston engage the rumble strips on the cylinder, a rumble may be heard and felt by the operator. This in turn indicates to the operator that the piston is near the end of its operative pumping range.
[0029] After the inflatable object 500 is inflated, the operator may remove the hand-actuated pump 100 by performing the reverse of the operations described above and then closing the valve on the inflatable object 500, as shown in Fig. 6c.
[0030] While the method and system has been described with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope. For example, the exhaust cover may be attached to the piston, and the valve cover may be attached to the cylinder. A strap and/or handle may or may not be utilized. The number of valves may be greater or fewer than two.
[0031] In addition, many modifications may be made to adapt a particular situation or material to the teachings without departing from its scope. Therefore, it is intended that the present method and system not be limited to the particular embodiment disclosed, but that the method and system include all embodiments falling within the scope of the appended claims.
