Description

CROSS-REFERENCES TO RELATED APPLICATIONS

The present application claims the benefit of U.S. Provisional Application No. 61/882,155, filed on Sep. 25, 2013, the full disclosure of which is incorporated herein by reference.

BACKGROUND

Inflatable mattresses or “airbeds” as they are often called, are commonly used to provide a temporary resting surface while camping or to provide additional sleeping accommodations for guests. One drawback to inflatable mattresses is the amount of time it takes to inflate the mattress. Similarly, inflatable pool toys, floats and the like also take time to inflate—the goal for the user again being a short inflation time. Most such inflatable mattresses and inflatable water recreation items are inflated using battery-operated or electric hand-held air pumps, although some use manual air pumps. The inflation nozzle of the air pump is inserted into the open valve on the product to be inflated and the pump is activated, resulting in inflation to the inflatable bladder of the product being inflated. It would be beneficial to have a device that is attachable to an existing air pump that would increase the rate of inflation of the air pump being utilized that is easy to use, easy to store and light-weight to carry.

BRIEF SUMMARY

The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.
An embodiment for a device for accelerating the inflation rate of an air pump includes an elongated tube having a sidewall, opposed open first and second ends, and a plurality of air inlets spaced around the exterior of the tube between the open ends, the first open end having a nozzle connectable to the valve of a product to be inflated and the second open end having an adaptor connectable to an inflator outlet, the acceleration device using the venture principle to increase air flow into the product to be inflated.
In embodiments described herein, the acceleration device has a closure mechanism that operates to disrupt the air flow into the air inlets when a certain pressure within the product to be inflated is attained.
For a fuller understanding of the nature and advantages of the present invention, reference should be made to the ensuing detailed description and accompanying drawings.

DETAILED DESCRIPTION

In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. It will also be apparent to one skilled in the art, however, that the present invention may be practiced without the specific details.
Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.
Referring now to the drawings, in which like reference numerals represent like parts throughout the several views, FIG. 1 shows an air inflation accelerator device 10 of an embodiment of the present invention. The air inflation accelerator device 10 comprises base 12, nozzle 14, air intake inlets 18, and adaptor 26.
Base 12 is a cylindrical tube having opposed open ends 13, 15. Nozzle 14 and nozzle stop 16 are located at a first open end 13. Nozzle 14 is shaped and sized to fit into the valve 32 of the product 34 to be inflated, as shown in FIGS. 3 and 4. Nozzle 14 comprises nozzle stop 16 which forms a collar around the perimeter of nozzle 14 located most opposite to open end 13 to provide a physical barrier to prevent over-insertion of the nozzle 14 into the valve 32 and also to provide a stop for the inlet closure 20. Although it is preferred for use with a double-lock type valve, nozzle 14 can be shaped and sized to fit any valve in the industry. It is also within the scope of the present invention to provide a separate nozzle adaptor (not shown) to accommodate different types and shapes of valves as such nozzle adaptor are known in the industry.
Adaptor 26 is located at a second open end 15. Adaptor 26 comprises locking notch 24 which is a slot located in the sidewall of the base 12 near the edge of open end 15. Locking notch 24 is shaped and sized with a channel 25 for receipt of a locking pin 28 that is located on the inflator outlet 30. As shown in FIGS. 3 and 4, locking pin 28 is inserted into channel 25 and base 12 is rotated so that locking pin 28 locks into place in locking notch 24. As shown in the figures, there are two locking notches 24 preferably located on opposite sides of base 12. It is certainly within the scope of the present invention, however, for only one locking notch 24 to be present or for the shape of locking notch 24 to be other than a slot having an open channel. Other attachment and retaining means known in the industry can be used to ensure that the inflator outlet 30 is securely connected to adaptor 26. Adaptor 26 is comprised of natural or man-made materials and is shaped and sized to interface with the existing inflator outlet 30.
The base portion located between open ends 13 and 15 comprises a plurality of air intake inlets 18 spaced around base 12 which each extend entirely through the side wall of the base 12. Air intake inlets 18 are preferably round for ease of manufacture, but other shapes could also be utilized. Device 10 further includes inlet closure 20 which is shaped and sized to fit over base 12 from open end 15 in a sliding engagement. Collar 22 of inlet closure 20 provides an easy grip for a user to grasp inlet closure 20 and move it to the desired position and also assists in preventing inlet closure 20 from being moved too far onto inflator outlet 30.
Inlet closure 20 is movable from a first position (shown in FIG. 3) allowing air intake inlets 18 to function by permitting air to flow from the atmosphere through intake inlets 18 and into base 12, flowing into product 34 through valve 32 to a second position (shown in FIG. 4) blocking exposure of intake inlets 18 from the atmosphere. Intake inlets 18 increase the air intake volume to accelerate the rate of inflation of the inflator (not shown), using the venturi principle. Intake inlets 18 will increase the rate of inflation to a point where the internal pressure of the product 34 being inflated reaches atmospheric pressure. Once atmospheric pressure has been reached, inlet closure 20 is moved from the open first position to the closed second position so that the inflator can complete inflation of the product to the desired pressure above room pressure. Although the figures depict a manual inlet closure 20, it is also within the scope of the present invention for inlet closure 20 to be connected to a sensor and an actuator which moves inlet closure 20 into the closed second position once atmospheric pressure within the product 34 has been reached.
It is also within the scope of the present invention to include audible and/or visual alerts to signal when the inflatable bladder pressure reaches atmospheric pressure. An audible alert such as a whistle or other easily identifiable sound will activate when atmospheric pressure within the inflatable bladder is reached such that air begins to exit through the intake inlets. This alert will signal the user to move the inlet closure 20 over the intake inlets 18 or to activate an automatic inlet closure. Similarly, a visual alert such as a flashing light or a specific color of light will activate when atmospheric pressure within the inflatable bladder is reached such that aire begins to exit through the intake inlets. This alert will signal the user to move the inlet closure 20 over the intake inlets 18 or to activate an automatic inlet closure.
While the figures depict intake inlets 18 arranged in 2 rows around the circumference of base 12, it is within the scope of the present invention to have more or fewer rows and to have any number and size of holes within each row. The accelerated inflation enhancement feature of the present invention can be used with any existing or newly designed electric, battery, manual, built-in, handheld or foot inflator pump used to inflate inflatable products including air mattresses, pool floats and other recreational items.
While the present invention is shown and described as being connected to an inflator outlet 30, which could be a pump interface or a pump hose, it is also within the scope of the present invention for the device 10 to form an integrated and manufactured part of the inflator itself. It is further contemplated that the device 10 can form an integrated and manufactured part of the inflator even for built-in pumps which are integrated into the product being inflated.
Other variations are within the spirit of the present invention. Thus, while the invention is susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in the drawings and have been described above in detail. It should be understood, however, that there is no intention to limit the invention to the specific form or forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention, as defined in the appended claims.
