The claimed invention relates generally to the field of liquid dispensing systems and more particularly, but not by way of limitation, to an apparatus for transferring water to a bottled water dispenser.
Bottled water dispensers are employed in commercial and residential settings to provide a convenient source of potable water. Such dispensers often employ a base unit with one or more spigots to dispense the water from an internal reservoir. The base unit is often further configured to receivingly support an inverted water bottle above the reservoir. In this way, water empties from the bottle into the reservoir as water is correspondingly drawn from the reservoir through the spigot(s).
While operable, there are a number of limitations associated with this type of dispenser. The first limitation is the need to physically lift and place the water bottle onto the base unit. Such water bottles are usually relatively large and cumbersome; a full, standard five (5) gallon plastic bottle of water can weigh in excess of forty (40) pounds. The effort required to lift or carry a full water bottle can be strenuous for an adult male, and may be prohibitive for many women, children, elderly or handicapped persons.
Depending on the configuration of the bottle, water can be spilled through the neck opening of the bottle during the placement process. A water bottle can also crack open if inadvertently dropped, resulting in the flow of several gallons of water onto the floor. In situations where the volume of consumed water is relatively high, there is also the need to stockpile multiple full water bottles in a central storage location, and then to carry each full water bottle from this location to the base unit as needed.
Thus, as water dispensing units continue to enjoy widespread popularity, there remains a continual need for improvements to address these and other limitations of the prior art.
Preferred embodiments of the present invention are generally directed to an apparatus for transferring water to a bottled water dispenser.
In accordance with some preferred embodiments, a wand assembly is configured to engage a neck of a non-inverted water bottle to draw water therefrom. The wand assembly preferably comprises a housing with respective inlet and outlet ports. A bent, rigid first conduit is coupled to the outlet port and extends from the housing into an interior of the water bottle. The first conduit comprises a first segment extending in a first direction and a second segment extending from the first segment in a second direction non-parallel to the first direction. A second conduit is coupled to the inlet port and extends from the housing into the interior of the water bottle.
In this way, a flow of pressurized water from the water bottle passes along the first conduit and to the outlet port in response to a flow of pressurized air from a pressurized air source through the inlet port and the second conduit. Preferably, the first and second conduits are aligned so that the second conduit surrounds the first segment of the first conduit.
Preferably, the water bottle comprises a resealable stopper assembly with a central aperture passing therethrough to the interior of the water bottle. The first and second conduits are preferably adapted to sealingly pass through this central aperture. The stopper assembly further preferably comprises an interior removeable plug. The second segment of the first conduit comprises a distal end configured to engage said plug so that, as the first conduit is inserted into the bottle, the plug is removed from the stopper assembly and, as the first conduit is subsequently removed from the bottle, the plug is replaced onto the stopper assembly.
In further preferred embodiments, a water bottle transport assembly is adapted to transport a water bottle in a substantially non-inverted orientation. The transport assembly preferably comprises a rigid frame supporting at least one wheel and comprising a user handle, and a cradle supported by and rotatable with respect to the frame. The cradle comprises first and second support arms configured to contactingly support opposing first and second exterior sides of the bottle. The first and second support arms are further configured to pass adjacent to the respective first and second exterior sides of the bottle to engage said sides without lifting or tilting said bottle.
The cradle further preferably comprises a central support surface configured to contactingly support a third exterior side of the bottle between the first and second exterior sides. In this way, the bottle is tilted into a supported orientation in the cradle and the third exterior side of the bottle contactingly abuts the central support surface of the cradle.
In further preferred embodiments, a cover assembly is provided to sealingly cover an inlet aperture of the water dispenser unit, with the aperture being nominally configured to receive the water bottle in an inverted orientation to pass water from the bottle to an underlying reservoir.
The cover assembly preferably comprises an air pump coupled to a flexible third conduit to pass said flow of pressurized air to the inlet port. A flexible fourth conduit passes from the outlet port and through the cover assembly. Thus, upon operation of the air pump, said flow of pressurized air is directed along the third conduit and a return flow of said pressurized water is directed along the fourth conduit and into the reservoir.
These and various other features and advantages which characterize the claimed invention will become apparent upon reading the following detailed description and upon reviewing the associated drawings.
The water transfer system 100 preferably comprises three primary components: a wand assembly 108, a cover assembly 110, and a water bottle transport assembly 112. As explained in greater detail below, the wand assembly 108 is inserted into the water bottle 102 during operation, as depicted in the views of
The wand assembly 108 is retracted from the water bottle 102 when not in use (such as during a water bottle changing operation), as depicted in the views of
The cover assembly 110 is adapted to be supported over the interior reservoir in the dispenser unit 104. The cover assembly 110 provides a supply of pressurized air to the wand assembly 108 to pressurize the water bottle 102. This pressurized air is provided along a first flexible conduit 116, and results in the movement of water along a second flexible conduit 118 from the bottle 102 to the interior reservoir. Electrical power is provided to the cover assembly via cord 120.
The transport assembly 112 is preferably characterized as a modified “hand truck,” and facilitates movement of the water bottle 102 to a position adjacent the dispenser unit 104. The transport assembly 112 further preferably supports the water bottle 102 at a suitable, non-inverted angle (best viewed in
The housing 124 supports an air pump 130 which can take any number of suitable forms, such as a conventional aquarium pump. The pump 130 is coupled to the first flexible conduit 116 via outlet port 132 to supply the aforementioned supply of pressurized air thereto. A resulting flow of water from the second flexible conduit 118 flows through inlet port 134 and into the reservoir 122 as shown.
A level sensor 136 projects from the housing 124 toward the reservoir 122, and is electrically connected in series with the pump 130. The sensor 136 is preferably characterized as a magnetic reed switch with a float 138 that rises and lowers in relation to the level of water in the reservoir 122. The switch 136 opens when the water reaches line 140, and closes when the water falls below this level. In this way, the sensor 136 continuously regulates the amount of water present in the reservoir 122.
A user-activated on-off switch 142 is connected in series with the pump 130 and is located for easy access on top of the housing 124. A filtered vent aperture 144 permits inlet air to flow into the housing 124 to replenish that air pumped by the pump 130 along conduit 116.
The conduit 162, herein also referred to as a “first conduit,” preferably comprises a rigid, bent member having a first segment 164 which extends into the bottle 102 in a first direction (preferably along a central axis of the bottle 102). A second segment 166 extends from the first segment 164 in a second direction non-parallel to the first direction. Preferably, the second segment 166 terminates at a tip assembly 167 adjacent a junction between a base 168 and a sidewall 170 of the water bottle 102, as shown.
The transport assembly 112 preferably maintains the bottle 102 at a suitable non-inverted angle, such as about 20 degrees from horizontal. The respective lengths and angles of the rigid first and second segments 164, 166 can vary as desired, but are preferably selected to permit unrestricted insertion and retraction of the wand assembly 108 into the bottle 102, as well as to permit the tip assembly 167 to substantially reach the lowest extent of the bottle 102, as depicted in
The conduit 160, herein also referred to as a “second conduit,” preferably comprises an annular member which surrounds the first conduit 162. Unlike the first conduit 162, the second conduit 160 does not extend significantly into the interior of the bottle 102, but instead terminates in the vicinity of a neck portion 172 of the bottle 102. The neck portion 172 includes a sidewall 174 that forms a central opening for the bottle 162, and the second conduit 160 is preferably sized to form a compression seal against the sidewall 174 when the wand assembly 108 is inserted into the bottle 102 (best viewed in
The pressurized air from the pump 130 of the cover assembly 110 (
The pressurized vapor space 176 forces the water 178 from the water bottle 102 to flow up through the tip assembly 167, along the second segment 166 and then the first segment 164 of the first conduit 160, along interior channel 158, through port 154, along flexible conduit 118, through inlet port 134 (
As shown in
The transport assembly 112 comprises a rigid frame 184 which supports at least one rotatable wheel 186 (and preferably two as shown). The frame 184 includes a user handle 188 (best viewed in
The cradle 190 preferably comprises first and second support arms 192, 194 which are configured to slide under the opposing sides of the water bottle 102, as indicated by
While the support arms 192, 194 preferably engage the bottom of the bottle 102 (i.e., at the radiused junction between base 168 and sidewall 170), the arms 192, 194 can be alternatively configured to engage other opposing surfaces of the bottle, such as at a suitable point along the sidewall 170, as desired. A central support surface 196 further preferably engages another side of the bottle 102 to halt further sliding movement of the arms 192, 194 adjacent the bottle 102.
Once so engaged, the user applies a pivotal downward force upon the handle 188 to rotate the transport assembly 112 and the bottle 102 to the position shown in
Continued user rotation of the handle 188, however, ultimately shifts the center of gravity of the water bottle 102 to a sufficient point to induce rotation of the water bottle 102 and the cradle 190 with respect to the frame 184, as shown in
This rotation of the cradle 190 is preferably facilitated as follows. The cradle 190 is provided with opposing side walls 198, 200 with respective flanges 202, 204. The flanges 202, 204 extend adjacent the wheels 186 and are each provided with a central aperture through which a wheel axis 206 passes (the wheel axis also supports the wheels 186).
Elongated slots (one shown at 208) are provisioned in each of the sidewalls 198, 200, each terminating with a detent portion 210. Fixed pins (one shown at 212) project from the frame 184 and are captured in the respective slots 208.
Thus, as the transport assembly 112 is rotated from the position shown in
Once the transport assembly 112 is moved to the final destination (e.g., adjacent the dispenser unit 104), the user rotates the handle 188 back to the original, upright position as shown in
Once the contents of the water bottle 102 have been emptied into the reservoir 122 as explained above, the empty water bottle can be readily lifted out of the cradle 190 by the user. The cradle 190 can be reset to the original upright position of
While the preferred embodiments presented thus far have utilized a wand assembly 108 with a water drawing (first) conduit 162 with only two segments 164, 166, such is not necessarily limiting. For example,
As desired, the tip assembly 167 can be provisioned with a radiused engagement member 217 as shown in
As shown in
From the foregoing discussion it will be apparent that preferred embodiments of the present invention present several advantages over the prior art. The system 100 advantageously eliminates the need to lift, carry and invert the water bottle 102 in order to place the water from the bottle into the dispenser unit 104. The unique orientation of the wand assembly 108 ensures that practically all of the water from the bottle 102 is moved to the reservoir 122. The transport assembly 112 further advantageously eliminates the need to pick up or move by hand a water bottle, which can be particularly helpful in situations where multiple bottles are stored in a remote location and moved one at a time for use by the dispenser unit 104, or whenever users have limited physical strength or mobility, or to reduce the risk of back injury in otherwise healthy persons.
Accordingly, preferred embodiments of the present invention are generally directed to an apparatus for transferring water to a bottled water dispenser (such as 104).
In accordance with some preferred embodiments, a wand assembly (such as 108) is configured to engage a neck (such as 172) of a non-inverted water bottle (such as 102) to draw water therefrom. The wand assembly preferably comprises a housing (such as 148) with respective inlet and outlet ports (such as 152, 154); a bent, rigid first conduit (such as 162) coupled to the outlet port and extending from the housing into an interior of the water bottle, the first conduit comprising a first segment (such as 164, 214) extending in a first direction and a second segment (such as 166) extending from the first segment in a second direction non-parallel to the first direction; and a second conduit (such as 160) coupled to the inlet port and extending from the housing into the interior of the water bottle.
In this way, a flow of pressurized water (such as 178) from the water bottle passes along the first conduit and to the outlet port in response to a flow of pressurized air from a pressurized air source through the inlet port and the second conduit. Preferably, the first and second conduits are aligned so that the second conduit surrounds the first segment of the first conduit (as in
Preferably, the water bottle comprises a resealable stopper assembly (such as at 174) with a central aperture passing therethrough to the interior of the water bottle, wherein the first and second conduits are adapted to sealingly pass through said central aperture. The stopper assembly further preferably comprises an interior removeable plug (such as 180), and wherein the second segment of the first conduit comprises a distal end (such as 167, 218) configured to engage said plug so that, as the first conduit is inserted into the bottle, the plug is removed from the stopper assembly and, as the first conduit is subsequently removed from the bottle, the plug is replaced onto the stopper assembly.
In further preferred embodiments, a water bottle transport assembly (such as 112) is adapted to transport a water bottle in a substantially non-inverted orientation. The transport assembly preferably comprises a rigid frame (such as 184) supporting at least one wheel (such as 186) and comprising a user handle (such as 188), and a cradle (such as 190) supported by and rotatable with respect to the frame, the cradle comprising first and second support arms (such as 192, 194) configured to contactingly support opposing first and second exterior sides of the bottle, wherein the first and second support arms are further configured to pass adjacent to the respective first and second exterior sides of the bottle to engage said sides without lifting or tilting said bottle.
The cradle further preferably comprises a central support surface (such as 196) configured to contactingly support a third exterior side of the bottle between the first and second exterior sides, wherein upon engagement of said first and second exterior sides of the bottle by the first and second arms and downward pivotal movement of the handle, the bottle is tilted into a supported orientation in the cradle and the third exterior side of the bottle contactingly abuts the central support surface of the cradle (such as in
In further preferred embodiments, a cover assembly (such as 110) is provided to sealingly cover an inlet aperture (such as 128) of the water dispenser unit with the aperture being nominally configured to receive the water bottle in an inverted orientation to pass water from the bottle to an underlying reservoir (such as 122).
The cover assembly preferably comprises an air pump (such as 130) coupled to a flexible third conduit (such as 116) to pass said flow of pressurized air to the inlet port, and wherein a flexible fourth conduit (such as 118) passes from the outlet port and through the cover assembly so that upon operation of the air pump, said flow of pressurized air is directed along the third conduit and a return flow of said pressurized water is directed along the fourth conduit and into the reservoir.
For purposes of the appended claims, it will be understood that the recited “first means” corresponds to at least the disclosed wand assembly 108 and the cover assembly 110. The recited “second means” will be understood to correspond to at least the disclosed water bottle transport assembly 112.
It is to be understood that even though numerous characteristics and advantages of various embodiments of the present invention have been set forth in the foregoing description, together with details of the structure and function of various embodiments of the invention, this detailed description is illustrative only, and changes may be made in detail, especially in matters of structure and arrangements of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. For example, the particular elements may vary depending on the particular environment without departing from the spirit and scope of the present invention.
