An electric air pump (60) is preferably included which may be activated by a remote control (64), so that the bed (100) is self-expanding.
Description




TECHNICAL FIELD




The present invention relates generally to collapsible furniture, and more particularly to bedding which may be used for temporary purposes such as for overnight guests.




BACKGROUND ART




Temporary beds have been used for many years and come in many forms, from a simple futon or air mattress to more complex “hide-a-bed” style devices. Such temporary beds are most often used when guests, either expected or otherwise, stay overnight. In such cases, it is desirable that the temporary bed be quick and easy to assemble, comfortable, and collapse to a small configuration which can be easily and conveniently stored in a closet or storage cabinet. An air mattress has the advantage of deflating to a very compact size when the internal air pressure is released, and can be set up in a relatively short amount of time. The air pressure in the mattress gives good support to body members and the air can redistribute within the mattress slightly in response to greater weight loads in certain areas. It can thus conform to the user's body, is lightweight, and is generally easily portable, even when inflated.




However, air mattresses which are pitched on the floor of a dwelling, may be perceived as being less gracious than beds which are elevated from the floor. Elevated beds may have less intimate contact with floor dirt and grime, thus be more suitable for those with allergies or aversions to dirt. Furthermore, an elevated bed may be easier to get into and out of for those who may have trouble squatting on the floor, or for those with stiff joints or arthritis.




Additionally, those who go camping out of trailers, etc. may wish to sleep out-of-doors, but may wish to isolate themselves from insects, snakes and other forest denizens which may roam the forest floor. For such purposes, an elevated bed, which is easily collapsible and portable, may be very useful. It also may be useful in rocky terrain, or in areas of thorns or burrs, which would otherwise contact the air mattress and possibly puncture it.




Generally, the less effort involved in constructing the bed, the more desirable the typical user would consider the bed to be. People who are contemplating retiring to bed are often already in a state of fatigue or unsteadiness in which the construction of a bed from a collapsed configuration to an expanded configuration may seem a daunting prospect. Therefore, a bed structure which requires minimal involvement by the user in its construction, or, even better, is largely self-erecting, would be very desirable in a variety of situations.




Thus there is a need for a collapsible bed which is elevated from contact with the ground or floor, and which is both very portable and comfortable for the user. There is also a need for a bed which requires minimal involvement by the user in its construction, or, even better, is largely self-erecting.




DISCLOSURE OF INVENTION




Accordingly, it is an object of the present invention to provide a bed that is collapsible and portable.




Another object of the invention is to provide a bed which stores in a very small space.




And another object of the invention is to provide a bed which uses an air mattress which is elevated up off the floor.




A further object of the invention is to provide a bed which requires a minimum of human effort to construct from a collapsed configuration to an expanded one.




An additional object of the invention is to provide a self-expanding bed in which the self-erecting mechanism is operated by remote control.




Briefly, one preferred embodiment of the present invention is a collapsible bed having an air mattress and a support frame. The frame includes a number of frame members, which are joined by pivot assemblies, such that the support frame as a whole expands outwardly from a central area, when a portion of the frame is pulled outwardly.




A second preferred embodiment is a self-expanding bed having an air mattress and an articulated support frame. The frame includes a number of frame members, which are joined by pivot assemblies, such that the support frame as a whole expands outwardly from a central area. The air mattress is attached to the support frame at a number of points, so that when the air mattress is inflated and expands outwardly, the support frame also expands outwardly. An electric air pump may also be included, which may be activated by a remote control, so that the bed is self-expanding.




An advantage of the present invention is that it uses an external frame and independent air mattress.




Another advantage of the invention is that the air mattress can be replaced if damaged, without replacing the whole bed.




And another advantage of the invention is that the frame is constructed with permanently joined members connected with pivot joints so that the frame collapses and expands as a unit, and requires very little construction or hunting for lost pieces.




An additional advantage of the invention is that it contains an air-pump which can be activated by a remote control to cause the pump to fill the mattress. The force of the air in the mattress as it expands causes the frame structure to expand and move from its collapsed to its expanded configuration, with minimal, or no manual effort by the user.




These and other objects and advantages of the present invention will become clear to those skilled in the art in view of the description of the best presently known mode of carrying out the invention and the industrial applicability of the preferred embodiment as described herein and as illustrated in the several figures of the drawings.

BEST MODE FOR CARRYING OUT THE INVENTION




A preferred embodiment of the present invention is an air bed with a support structure. As illustrated in the various drawings herein, and particularly in the view of

FIG. 1

, a form of this preferred embodiment of the inventive device is depicted by the general reference character


10


.





FIGS. 1-3

illustrates an air bed with an elevated support structure


10


, having generally an air bed


12


which includes an air mattress


14


(not visible in

FIG. 1

) and a fabric covering


16


, and a support frame


18


. The fabric covering


16


includes generally a bag enclosure


20


having an entry mouth


22


which is sealed with a closure fastener


24


, which is preferably a zipper


26


, but which is also possibly any conventional device such as Velcro, hook-and-eye fasteners, etc. The fabric covering


16


can be plastic, cloth, leather, etc. and encloses at least a portion of the air mattress


14


, shown in

FIG. 2

, which is inserted into the entry mouth


22


, either before or after inflation. The zipper


26


is then closed to complete the installation of the air mattress


14


. The air mattress


14


can also be removed as desired through the same entry mouth


22


, again, either before or after the air mattress


14


is deflated. The air mattress


14


preferably has a number of cells


28


and at least one inflation port


30


through which air is introduced to inflate the air mattress


14


. The fabric covering


16


need not completely enclose the entire air mattress, but may enclose only a portion or portions such as the ends or sides of the air mattress


14


.





FIG. 3

shows the articulated support frame


18


which includes a number of frame members


32


which are attached to each other at pivots


34


, some of which are positioned at the midpoints of the frame members


32


, and some of which are included in pivot assemblies


36


in the feet


38


and upper connector assemblies


40


. These pivot assemblies


36


and pivots


34


connect all the frame members


32


to each other, so there are no loose pieces to be gathered and assembled. The frame can be thought of as an extended scissors-frame assembly


33


since the tops and bottoms of each pair of frame members


32


scissor together or apart. These scissor pairs


35


are then joined in an extended assembly where the ends of multiple pairs


35


are joined at the pivot assemblies


36


. They also allow the frame


18


as a whole to be collapsed or expanded in a very easy and efficient manner. Force directed at any one of the comers causes movement in all the other comers, so that there is movement of the whole frame in either an inward or outward direction, relative to a central area. The pivots


34


allow the frame structure


18


to move towards a central area


42


from all sides as a unit when the frame


18


is to be collapsed, and to move away from this central area


42


when expanding.




This configuration will be spoken of as “expanding outwardly from a central area”, although it is to be understood that one of the feet may actually remain in fixed position, while the remainder of the feet move outward. In other words, the central reference area from which the feet move, may itself move laterally. One example of this occurs when the collapsed support frame is placed in the comer of a room, where, say, the left rear foot of the frame is in the left rear comer of the room, and thus is constrained from movement in a further leftward or rearward direction. When the frame expands, all the other, non-constrained feet will expand outwardly from a central area to the right, or forward, or both, even as the central area itself will move to the right and forward, relative to the immobile left rear foot.




It should also be understood that all the lines of direction of the movement of the feet are not expected to intersect at a precise point. The central area


42


is thus a relatively small region from which the feet


38


move outwardly, but there should be no inference that all feet must move in a specific lines, such as radially from a single specific center point. To one skilled in the art, it will be apparent that if such precise directionality were attempted, manufacturing errors would inevitably introduce variations. Thus, the expansion is considered to move outwardly from a central area or region, and should not be construed to imply any particular lines of direction, other than generally outward from this central area. The direction arrows and central area


42


shown in

FIG. 3

, and later in

FIGS. 12 and 13

below, are therefore not provided to show specific lines of movement which must be followed, but merely a general direction of movement towards, or away from, a general central area


42


.




The articulated frame


18


also optionally includes support webbing


44


, which may have hooks (not shown) which anchor the support webbing to the frame members


32


and/or the upper connector assemblies


40


, and may also have attachment points (not shown) for securing the fabric covering


16


to the webbing


44


and thus to the frame


18


.





FIGS. 4 and 5

show closer views of the assembled air bed


10


in which several of the pivot assemblies


36


are selected for detail views in detail circles A-F. The pivot assemblies


36


of the feet


38


and the upper connector assemblies


40


in this embodiment are made to receive


4


connections and thus will be called four-pivot connectors


46


. These are preferably reversible, so that the same four-pivot connector


46


can be used as a foot


38


and as an upper connector assembly


40


, thus making for uniformity, and ease of manufacturing. The frame members


32


too are preferably interchangeable and of uniform length, with the exception of the comer uprights


48


, which are positioned in each of the four comers. These are composed of two or more comer members


50


, which may slide within each other in order to extend or contract in length. This is desirable because when the frame


18


is in collapsed position, the comer uprights


48


must be of greater length than when the frame


18


is expanded. In the expanded position therefore, one of the comer members will preferably slide within the other, as shown in

FIGS. 6 and 10

below.





FIG. 6

illustrates a foot


38


, a type of four-pivot connector


46


, which is seen in detail circle A of FIG.


4


. Frame members


32


, pivots


34


, and comer upright


48


and its included comer members


50


are shown.





FIG. 7

shows a foot


38


, a type of four-pivot connector


46


, which is seen in detail circle B of FIG.


4


. Frame members


32


, and pivots


34


are also shown.





FIG. 8

illustrates a foot


38


, a type of four-pivot connector


46


, which is seen in detail circle C of FIG.


4


. Frame members


32


, and pivots


34


are shown.





FIG. 9

shows an upper connector assembly


40


, a type of four-pivot connector


46


, which is seen in detail circle D of FIG.


5


. Frame members


32


, comer upright


48


and its included comer member


50


are also shown.





FIG. 10

illustrates a foot


38


, a type of four-pivot connector


46


, which is seen in detail circle E of FIG.


5


. Frame members


32


, comer upright


48


, pivots


34


and its included comer members


50


are shown.





FIG. 11

shows an upper connector assembly


40


, a type of four-pivot connector


46


, which is seen in detail circle F of FIG.


5


. Frame members


32


, and pivots


34


are also shown. Referring now also to

FIGS. 1 and 2

, thus the assembly sequence allows for the support frame


18


to be placed upright, expanded, the fabric covering


16


attached to the frame


18


and the air mattress


14


inserted into the entry mouth


22


of the bag enclosure


20


, and the fastener


24


closed, and the bed is ready to receive bed clothes, or be otherwise used.




A useful variation on this invention is an air-bed with a self-expanding support structure. This is shown in

FIG. 12

as element


100


. The structure and elements are much the same, and when elements correspond to those used previously, the same element numbers will be used.




The air-bed


12


with air mattress


14


is attached to a support frame


18


, either directly, or preferably through a bag enclosure


20


. The attachment may be permanent or removable, by such conventional means as buttons, snaps, Velcro®, etc., but it is important that the air mattress


14


, as it expands, is attached at multiple points to the frame


18


, so that the frame


18


is urged to move with the expansion of the air mattress


14


, as discussed below. There is a fabric covering


16


as described previously, which may also be the bag enclosure


20


, which protects the air mattress


14


from damage at points where it is rubbed against the frame structure


18


while inflating or deflating.




An air pump


60


is connected to an inflation port


30


. The air pump


60


is electrically operated, and can be powered either by wall current or by batteries. If batteries are used, they may be included in a battery pack (not shown). The air pump


60


preferably includes a sensor


62


, which can be operated by a beam


66


or communicating means from a remote control


64


. The beam


66


or communicating means is preferably cordless, such as radio or infra-red diode laser beam, etc. The remote control


64


preferably has an on-off button


68


, which activates and deactivates the electric pump


60


. This remote control


64


is by no means a necessity, and the air pump


60


will preferably have a manual on-off switch


70


for back-up operation if the remote


64


is misplaced or the remote's batteries are low, or if the bed


100


is designed not to be operated by remote control at all.




In operation, the bed


100


will be assumed to start in a collapsed configuration


72


, as in FIG.


12


. The mattress


14


is squeezed together and is generally surrounded by the support frame


18


, the frame


18


previously having been drawn together towards the central area


42


, discussed above. The frame


18


is set upon its feet


38


, and the air pump


60


is activated, either by operation of a manual on-off switch, or by pressing the button


68


on a remote control


64


. The air pump


60


begins filling the air mattress


14


which then begins to expand generally out from the central area


42


, as indicated by the direction arrows


76


in FIG.


13


. As the mattress


14


expands it presses on the members of the frame


18


, which pushes them also in the direction away from the central area


42


. The feet


38


may be optionally fitted with low friction pads which can thus slide across floor surfaces, or may also be fitted with wheels to allow the frame


18


to expand easily and without hindrance.




The air pump


60


may be permanently attached to the mattress


14


, or it may be removable in order to allow access to the inflation port


30


by either a hand pump or by mouth in case electrical power is unavailable for the electrical pump


60


, or if it breaks down.





FIG. 14

shows an isometric view of an air mattress


14


and air pump


60


which has been attached to the inflation port


30


of the air mattress


14


.

FIG. 15

shows a detail view of the inflation port


30


from which the air pump


60


has been removed. Referring to both

FIGS. 14 and 15

, the air mattress


14


preferably has a recess area


78


into which the inflation port


30


has been seated. This recess area


78


allows the air pump


60


to fit smoothly without extending far beyond the perimeter of the mattress


14


, thus protecting it from being bumped or knocked away from its position at the inflation port


30


. Thus, the air pump


60


can be maintained in position after the inflation is complete. Of course, the use of a recess area is optional and should not be considered as a limitation. Also, the air pump


60


may be made to be routinely removed after operation. In this case a self-sealing valve (not shown) is provided for the air mattress


14


. A manual on-off switch


70


is also shown, which is preferably included even when the pump


60


is expected to be operated by remote control.




Another optional feature is a secondary inflation port


80


, which may be used for attachment of a manual air pump or for inflation by lung power. This may be a conventional air valve as generally used in air mattresses. It may also be used as a venting port


82


for allowing air pressure out of the mattress


14


if the air pump


60


is to be maintained in position, perhaps permanently.




The preferred embodiment


100


of this invention uses an air pump


60


which is removable. The air pump


60


and inflation port


30


are preferably fitting with a friction lock (not visible) similar to those used to attach lens to cameras, and which forms an airtight seal between the two parts.




The pump


60


also preferably contains a pressure sensor or self-regulator (not visible) which detects or acts when the air pressure in the mattress


14


has reached a predetermined level, and which then shuts off the air pump


60


. This is also not a required feature and should not be construed as a limitation.




As mentioned above, the electrical air pump


60


may be operated from batteries, perhaps from a battery pack. The bed


100


is thus usable in the outdoors or in a cabin which is not equipped with power lines.




While various embodiments have been described above, it should be understood that they have been presented by way of example only, and not limitation. Thus, the breadth and scope of a preferred embodiment should not be limited by any of the above described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.




INDUSTRIAL APPLICABILITY




The embodiments of the present invention


10


,


100


present an easy and attractive way of providing bedding for overnight guests or visitors. The articulated support frame


18


which includes a number of frame members


32


which are attached to each other at pivots


34


, which are positioned at the midpoints of the frame members


32


and at pivot assemblies


36


in the feet


38


and upper connector assemblies


40


. These pivot assemblies


36


and pivots


34


connect all the frame members


32


to each other, so there are no loose pieces to be gathered and assembled. They also allow the frame


18


as a whole to be collapsed or expanded in a very easy and efficient manner. Force directed at any one of the corners causes movement in all the other corners, so that there is movement of the whole frame in either an inward or outward direction, relative to a central area


42


. The pivots


34


allow the frame structure


18


to move towards a central area


42


from all sides as a unit when the frame


18


is to be collapsed, and to move away from this central area


42


when expanding.




In operation, the bed


10


,


100


will be assumed to start in a collapsed configuration


72


. The mattress


14


is squeezed together and is generally surrounded by the support frame


18


, the frame


18


previously having been drawn together towards the central area


42


, discussed above. The air mattress


14


is preferably attached to the frame


18


at multiple points, either directly, or by being at least partially enclosed by a fabric covering


16


which is, in turn, attached at multiple points to the frame


18


. The frame


18


is set upon its feet


38


, and inflated, either by the user's lung power or by activation of an electric pump


60


. If the preferred air pump


60


is used, it is activated, either by operation of a manual on-off switch, or by pressing the button


68


on a remote control


64


. The air pump


60


begins filling the air mattress


14


which then begins to expand generally out from the central area


42


. As the mattress


14


expands it presses laterally on the members of the frame


18


, which pushes them also in the direction away from the central area


42


. The feet


38


may be optionally fitted with low friction pads which can thus slide across floor surfaces, or may also be fitted with wheels to allow the frame


18


to expand easily and without hindrance.




The present invention


10


,


100


will find much application in user's homes, in commercial travel lodges, such as hotels, etc. where an extra bed may be needed, and may also find use in business offices to replace the occasional folding cot presently used by workaholics.




For the above, and other, reasons, it is expected that the air bed with elevated and self-expanding support structure


10


,


100


of the present invention will have widespread industrial applicability. Therefore, it is expected that the commercial utility of the present invention will be extensive and long lasting.
