Description
CROSS-REFERENCE TO RELATED APPLICATION

This application is a 35 U.S.C. § 371 national stage application of and which claims priority to PCT Application Ser. No. PCT/CN2017/106523, filed on Oct. 17, 2017, which is hereby incorporated by reference in its entirety.


TECHNICAL FIELD

The present subject matter relates to inflatable beds, and more particularly, to a manually operable pump for filling inflatable beds with air.


BACKGROUND

Often times, inflatable consumer goods, such as pool toys, inflatable mattresses, etc., require that a consumer use lung-power to inflate the product. Alternatively, some inflatables are compatible with a pump. Suitable pumps may be separate from the inflatable or integrated therein. Regardless, pumps take up space, add weight, and require a power source, such as batteries and/or an electrical connection. A separate pump is stored with and/or transported with the inflatable for use therewith, while lung-powered inflatables often require the mouth of the user to be placed on the product. Pumps fill the inflatable quickly and with relative ease for the user, and lung-powered inflation may be slow and tiring for the consumer. A conveniently transportable inflation mechanism that is easily operated by the user represents an improvement in the art.


SUMMARY

According to an aspect of the disclosure, an inflatable air mattress system comprises an inflatable air mattress defining an air chamber and including an inlet passageway, an inflation valve mounted to the inflatable air mattress, and a connector. The valve defines a passageway that includes a lip and a valve member. Further in accordance with this aspect, the valve member includes a seal movable between a closed position wherein the valve member is at least partially covering the lip. When in an open position, inflation air can pass through the passageway and into the air chamber of the mattress. Still further, the inflatable air mattress system includes an inflating bladder including an interior portion defined by at least one wall of flexible fabric having a first end and a second end. The first end includes a wide opening by a closing spring, while the second end includes an outlet adapted to connect to the connector. The inflating bladder is configurable to force a quantity of air from the interior of the inflating bladder, through the connector, and into the air mattress to inflate the mattress.


According to another aspect of the disclosure, a method of inflation includes the steps of coupling a first end of an inflating bladder to an inflatable with a valve connector, opening the second end of the inflating bladder, closing the second end of the inflating bladder to capture air within the inflating bladder, and folding the second end of the inflating bladder towards the valve connector to force air through the valve connector and into the inflatable.


According to yet another aspect of the disclosure, an inflation system includes an inflatable having an interior air chamber and an inflating bladder with first and second ends. Further in accordance with this aspect, the first end of the inflating bladder is detachably coupled with the inflatable, and the second end has an opening for taking air into the inflating bladder. Still further, the system has a closing spring for capturing air within the inflating bladder such that movement of the second end of the inflating bladder towards the first end of the inflating bladder forces air from the inflating bladder into the inflatable.


Further according to aspects of the disclosure, an inflation system includes an inflatable with an air chamber inside same, and an inflation valve mounted to the inflatable. In accordance with this aspect, the valve defines a passageway through which air can pass into the air chamber of the air mattress, and an inflating bladder further includes an interior portion defined by at least one wall of flexible fabric having a first end and a second end. Still further, the inflating bladder has a wide opening at the first end thereof securable by a closing spring, while the second end of the inflating bladder includes an outlet having a connecting tube insertable through the inflation valve of the inflatable so as to open the passageway. Additionally, the inflating bladder is configurable to force a quantity of air from the interior of the inflating bladder, through the inflating bladder connecting tube, and into the air chamber of the inflatable.


Other aspects and advantages of the present invention will become apparent upon consideration of the following detailed description and the attached drawings wherein like numerals designate like structures throughout the specification.

DETAILED DESCRIPTION

The detailed description set forth below is intended as a description of various implementations and is not intended to represent the only implementations in which the subject technology may be practiced. As those skilled in the art would realize, the described implementations may be modified in various different ways, all without departing from the scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive.


Referring now to FIG. 1A, a system 100 for inflating an inflatable 102, such as an inflatable mattress, with an inflating bladder 104 is depicted. In this example embodiment, male and female connecting portions 106, 108 of a connector 118 are disposed on the inflation bladder 104 and the inflatable 102, respectively. As illustrated in FIGS. 1-3, the female connecting portion 108 is disposed on a side end 112 of the inflatable 102, while the male portion 106 is disposed on an air outlet end 114 of the inflating bladder 104. An air intake end 116 of the inflating bladder 104 is arranged opposite the air outlet end 114. It should be understood that it is within the scope of the present disclosure that the male and female connecting portions 106, 108 may be disposed on the opposite component as compared with the illustrated embodiments, i.e. the male connecting portion 106 may be disposed on the inflatable 102, while the female connecting portion 108 may be disposed on the inflating bladder 104. FIG. 1B depicts the inflating bladder 104 configured as a storage compartment 166 for housing the inflatable 102 during storage and/or transport thereof.


Referring now to FIGS. 2 and 3A, the connector 118 is shown in detail. The male portion and female portions 106, 108 are shaped so as to fixedly couple the inflating bladder 104 and the inflatable 102 during inflation thereof. The male connecting portion 106 has first, second, and third concentric ridges 120a-c arranged about a passageway 122 through which air passes upon operation of the inflating bladder 104. The female connecting portion 108 has a resilient flange 124 disposed therein. As illustrated in FIG. 3A, the resilient flange 124 flexes to fit behind the first concentric ridge 120a thereby attaching and sealing the male and female connecting portions 106, 108. Furthermore, attachment of the male and female connecting portions 106, 108 operatively couples the inflating bladder 104 with the inflatable 102. The resilient flange 124 presses against the first concentric ridge 120a to create a seal between the inflating bladder 104 and the inflatable 102 so that air does not escape through the connection of the male and female connection portions 106, 108. One or more rubber O-rings may be disposed within and/or along the first concentric ridge 120a and/or the resilient flange 124.


Example embodiments include threading disposed on the male portion 106 of the connector 118. Complementary threading may be disposed within the female connecting portion 108 such that the male portion 106 may be screwed into the female portion 108 couple the male and female portions 106, 108 of the connector 118. Additionally, one or more rubber washers or seals may be disposed within and/or about the male and female connecting portions 106, 108, together or separated from the threading, so as to aid creation of a seal therebetween and to decrease the amount of air leaked through the connector 118 during the inflation operation described hereinbelow with reference to FIGS. 4 and 5. Alternatively, the male and female connecting portions 106, 108 may be attached to one another by a set of bayonet pins disposed on one of the connecting portions 106, 108 while complementary hole are disposed on the opposite one of the connecting portions 106, 108 for insertion therein. In an example embodiment, a pair of bayonet pins may be disposed on the male connecting portion 106 such that same extend through associate holes in the female connecting portion when the two portions 106, 108 are snapped together. The male and female connecting portions 106, 108 may be formed from relatively hard plastic and/or metal components. The hardened plastic of the connector 118 lends structural integrity and reliability to the inflating system 100. Constructing such components from relatively strong material may provide reliability and durability to the connector 118, even helping to ensure successful operation of the valve system 110 during repeated and heavy usage.


In example embodiments, a one-way inflation valve 126 is configured within the female connecting portion 108. The one way inflation valve 126 may include a valve stem and a spring associated therewith. During operation of the inflating bladder 104 air pressure may cause compression of the spring allowing passage of air through a passageway 156 formed within the inflation valve 126. When air pressure is not present from the exterior of the inflation valve 126, a seal of the inflation valve 126 may occlude the passageway 156 therethrough. However, once air pressure is greater outside the inflatable 102 as compared to within an interior chamber 160 of the inflatable 102, the seal may open the passageway 156 allowing air to pass therethrough and into the interior chamber 160 of the inflatable 102. The valve 126 may be configured as a ball check valve, a tilting disc check valve, a lift-check valve, an in-line check valve, a duckbill valve, a pneumatic non-return valve, or any other suitable valve structure. Also, in the alternative, a valve stem and spring may be depressed to open the valve 126, or the seal may be deformed or pushed away from the passageway 156, via a protrusion extending from the connector 118 of the inflating bladder 104 or by another manual depression technique. For example, a protrusion on the inflating bladder 104 or on a valve stem or any other part of the valve 126 may cause opening of the valve 126 upon connection between the inflating bladder 104 and the inflatable 102. An additional valve 170 may be disposed to block air from escaping the interior chamber 160.


In an example embodiment depicted in FIG. 3B, the one-way valve may be a tilting disc valve 142 and a tube 144 may be inserted through the tilting disc valve 142 to hold open a disc 146 that otherwise is closed against an interior side 148 of the valve 142 by spring power, pressure, or another suitable mechanism or combination of mechanisms. The tube 144 may be integral with the male connecting portion 106 of the inflating bladder 104 or the tube 144 may be a separate component. The tube 144 extends between the inflating bladder 104 and the inflatable 102 providing a passageway 150 for moving air therebetween.


Referring now to FIGS. 4 and 5, operation of the inflating bladder 104 is illustrated. A spring and/or closing mechanism 132 opens and closes the air intake end 116. When the air intake end 116 is open, air enters the inflating bladder 104. Then the closing mechanism 132 operates to seal the air intake end 116 thereby capturing air within the inflating bladder 104. The spring and/or closing mechanism 132 may be a magnet, reusable adhesive, leaf spring, taper spring, torsion spring, flat spring, elastic material, or any other suitable mechanism for holding together the material of the inflating bladder 104 at the air intake end 116. In the example embodiment illustrated in FIG. 4, first and second magnetic strips 134a, 134b are disposed along first and second edges 136a, 136b of the air intake end 116 of the inflating bladder 104. The first and second magnetic strips 134a, 134b are of opposite polarization and have a moderate magnetic attraction to one another. The magnetic attraction snaps the strips together and in alignment thereby bringing together the first and second edges 136a, 136b. Thus, the first and second magnetic strips 134a, 134b hold the first and second edges 136a, 136b together loosely sealing the air intake end 116 and, thus, capturing air within an interior compartment 138 of the inflating bladder 104. Further, the resilience of the spring and/or closing mechanism 132 may be varied in order to increase the seal created thereby or increase ease of use, as desirable.


In alternative example embodiments, the closing mechanism 132 may be a spring 162 (FIG. 1) or other suitably resilient component. The spring 162 may be of one or more pieces disposed on or within the first and second edges 136a, 136b of the air intake end 116 of the inflating bladder. The first and second edges 136a, 136b may also be a single continuous edge with an elongate spring disposed therealong. The spring 162 may have a first, natural position corresponding to a closed configuration of the air intake end 116 of the inflating bladder 104. In this example embodiment, the spring 162 may be opened to allow air to enter the inflating bladder 104, subsequently snapping back to the first, natural position, closing the air intake end 116, and capturing air within the inflating bladder 104. In example embodiments, the resiliency of the spring 162.


As shown in FIG. 4, magnetic strips 134a, 134b do not need to create an airtight or strong seal, although the magnetic strips 134a, 134b may produce such a seal, between the first and second edges 136a, 136b. Instead, a user 140 performs a rolling and/or folding maneuver on material of the inflating bladder 104 beginning at the air intake end 116. During the rolling and/or folding maneuver, for example, the user 140 may use a twisting motion to fold and/or wrap the material of the inflating bladder 104 about the held together and aligned first and second magnetic strips 134a, 134b. The rolling and/folding of the material creates a seal that is substantially art tight. Consequently, the seal created does not need to prevent all leakage of air to be effective and so air-tightness is not required of said seal. Instead, the rolling and/or folding maneuver creates a seal sufficient to force air through the air passageway 122 of the connector 118 and further through the one-way inflation valve 126. To continue forcing air out of the inflating bladder 104, the user 140 may continue to fold and/or roll the fabric of the inflating bladder 104 or the user 140 may perform other motions in addition to rolling and/or folding including, but not limited to, smashing, pushing, stepping on, and/or squeezing in order to force additional air out of the inflating bladder 104 and into the inflatable 102. Further, once an amount of the flexible fabric of the inflating bladder 104 is rolled/folded over the magnetic strips 134a, 134b and/or spring 162, the folded material forms a handle 164. The handle 164 may aids the user 140 in performing a pumping motion with the inflating bladder 104 by grasping the handling and pushing the inflating bladder 104 towards the air-exiting end 114 of the inflating bladder 104.


Upon forcing an amount of air from the inflating bladder 104, the user 140 may unroll and/or unfold the inflating bladder 104. Then the user 140 separates the first and second magnetic strips 134a, 134b thereby opening the relatively large air intake end 116 and allowing air to fill the inflating bladder 104 once again. Next, the user 140 may reseal the air intake end 116 by bringing the first and second magnetic strips 134a, 134b into proximity with one another to re-seal the inflating bladder 104. The user 140 may repeat the opening, filling, sealing, and rolling/folding steps as necessary to adequately fill the inflatable 102.


In example embodiments of the system 100 described hereinabove, the inflating bladder 104 may also serve as a bag for carrying the inflatable 102. For example, it may be possible to fold up an inflatable mattress for insertion into the inflating bladder 104 for storage and transport thereof. (See FIG. 1B). Further, the inflating bladder 104 may have an alternative use as a pillow. Following inflation of the inflatable 102 in accordance with the above description, the inflating bladder 104 may be filled with air and sealed. Then the magnetic strips 134a, 134b of the inflating bladder 104 may be folded over once or more before first and second clips 152a, 152b attached to first and second nylon straps 154a, 154b are clipped together holding the folded portion of the inflating bladder 104 in the sealed position. The inflated bladder 104 may then be used as a pillow in conjunction with the inflatable 102. To facilitate use of the inflating bladder 104 as a pillow, a cap may be applied to the male portion 106 of the connector 118, thereby sealing the inflating bladder 104 on the air outlet end 114 thereof, rather than allowing air to be push through the passageway 122 of the male connecting portion 106, as is the case during the inflation operation described hereinabove. In another example embodiment, the inflatable 102 may further include a dump valve disposed separately from or alongside the inflation valve 126. The dump valve allows for rapid release of air during deflation of the inflatable 102, such as for storage or transport thereof.


INDUSTRIAL APPLICABILITY

The above disclosure may represent an improvement in the art because it allows for use of the inflatable without a pump and without the laborious task of lung-powered inflation. Further, this disclosure provides the user with improved storage and transport of the inflatable within the inflating bladder while doing away with the storage and transport of pumps and/or associated power sources. Still further, the disclosure improves the art by supplying an alternative use for the inflating bladder as a pillow.
