DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(15) A wide variety of tables could be constructed in accordance with the invention as defined by the claims. Hence, while the preferred embodiments of the invention will now be described with reference to a portable battery charging table, it should be understood that the invention is in no way so limited.
(16)
(17) Referring now to
(18) Referring again to
(19) In one embodiment of the invention, the tabletop 20 is made of a substrate laminated material, such as high density particle board covered with high pressure laminate for strength and durability. Tabletop 20 may further include a reinforced edge 21, such as polyurea coating, urethane edging, or aluminum edging, for additional durability and comfort. The reinforced edge 21 helps to resist moisture, debris, and tampering, while also being impact and puncture resistant.
(20) Still referring to
(21) The base 16 may be supported on the ground by a plurality of wheels 36, such as caster wheels, which allow for improved mobility of the table 10. The wheels 36 may be peripherally disposed on the prongs of a spider base defined by generally horizontally extending prongs 35. The spider base may comprise of 4-prongs (e.g., arranged in a cross formation, as shown) or as a 3-prong or 2-prong spider base, as understood in the art. Alternatively, the wheels 36 may support a round or rectangular base with the wheels 36 arranged underneath and along the perimeter of the base in a symmetric and balanced manner. In this regard, the table 10 may be easily moved to public meeting places, such as a schools, conference centers, or airports. In an alternative embodiment, the base may rest upon the ground without any wheels 36.
(22) In one embodiment of the invention, the base 16 or a portion of the base 16 is made of commercial-grade cast iron, steel (e.g., 12 gauge steel or 14-gauge steel), stainless steel, or aluminum. If the tabletop 20 is to be used while the user is standing, the base 16 height may be approximately 40 inches, and if the tabletop 20 is to be used while the user is sitting, the base 16 height is approximately 28 inches to allow for chair(s) to fit underneath the tabletop 20.
(23) The charging hub 22 has a plurality of ports 38, such as USB ports, easily accessible from the first surface 26 of the tabletop 20, and electrical connectors stored below the first surface 26 and hidden out of sight. The ports 38 could comprise USB ports and/or any combination of specialized ports configured for coupling to then-popular portable electronic devices 12. It is contemplated that different ports 38 may be available on the charging hub 22, such as standard 110 or 120 volt outlets or other desirable charging outlets.
(24)
(25) The battery compartment 18 is mounted on an upper end of the base 16 and supports the tabletop 20. The battery compartment 18 comprises a body 42 and a lid 40 coupled to the body 42 by a hinge assembly 44. The lid 40 is affixed to or recessed in the second surface 28 of the tabletop 20 to, in effect, pivotally connect the tabletop 20 to the base 16. In one embodiment, as seen in
(26) The body 42 has front 50, back 52, left 54 and right 56 sidewalls enclosed at a lower edge by a bottom wall 58 defining the battery compartment floor. The top edges of the front 50, back 52, left 54 and right 56 sidewalls define the compartment opening 60. The battery compartment 18 is shown with a generally rectangular construction; however, it is contemplated that the battery compartment 18 may be any number of shapes and sizes, depending on the size and shape of the battery 24 or batteries to be housed therein. As shown, the battery compartment 18 is slightly tapered from its upper end to its lower end so as to provide a greater surface area at the compartment opening 60 compared to a smaller surface area at the compartment floor 58. The compartment opening 60 has a surface area smaller than the surface area of the second surface 28 of the tabletop 20 so that the tabletop 20 overlaps and overhangs past the compartment opening 60. As seen in
(27) Referring to
(28) As understood in the art, the battery 24 may include an electrical connector 68 for delivering electrical current to the desired destination. In one embodiment, the electrical connector 68 of the battery 24 may couple with the charging hub 22 via a cord or cable 70. The cable or cord 70 may extend through the opening 48 of the tabletop 20 and the compartment lid 40.

(35) In use, the charging table 10 is transported to a desired location by pushing it on its wheels 36. The charging table assembly 10 is easy to store and transport when the tabletop 20 is in the second, flipped up position because the tabletop 20 extends generally vertically and does not take as much breadth as it does when it is in its flipped down position However, it is understood that the table assembly 10 may be transported with the tabletop 20 in either the flipped down or flipped up positions.
(36) Once in the desired location, the tabletop 20 is moved, or maintained at, the first, flipped down position. As seen by the resulting operative position in
(37) The charging hub 22 may include a visual indicator, e.g., a strip of LED lights, showing that the battery 24 is sufficiently charged or is below a certain power level and will need to be recharged soon. For example, a first colored indicator, such as a blue light, may show that the battery 24 has adequate power on reserve, and a second colored indicator, such as a red light, may indicate that the battery 24 is below a certain designated power level, e.g., less than 20% battery charging power remaining. Alternatively, a lower battery power condition may be indicated by blinking lights or other visual indicators. A low power condition also could be indicated audibly, such as by an intermitted beep.
(38) When it is desired to service the electrical components within the battery compartment 18 or recharge the battery 24, the tabletop 20 is moved to the second, flipped up position. As seen by the resultant open position in
(39) As seen in
(40) When the user is done servicing the battery 24 and/or electrical components, the tabletop 20 may return to the first, flipped down position for operative use. The user may transport the table assembly 10 to storage when the table assembly 10 is no longer needed. The tabletop 20 may be moved to the flipped up position in storage to take up relatively less storage area.
(41) With reference now to
(42) Also as in the first embodiment, the tabletop 120 is attached to a lid 140 of the battery compartment 118 which, in turn, is pivotally mounted to a body 142 of the battery compartment 118 by a hinge assembly 144 as described above in connection with the first embodiment. The tabletop 120 can be held closed by a latch assembly 174 including a latch 180 that selectively engages an opening 196 in the front sidewall 150 of the battery compartment 118. The latch 180 is spring-biased into its closed position and can be retracted from the opening 196 by manual operation of a handle 189, which translates an arm 187 to retract the latch 180. The latch 180 can be locked in its engaged position by a bolt 194 of a lock 192.
(43) As mentioned briefly above, the table 110 of this embodiment has an integrated battery charger 200 that is incorporated into the table 110 so that the battery 124 can be charged without removing it from the table 110 and without having to access the interior of the battery compartment 160. In this case, the table 110 is provided with a power cord 202 having a plug 204 for connecting the integrated battery charger 200 to a source of power. In this case, the tabletop 120 would only need to be moved out of its deployed position for battery service or end-of-life replacement. However, relatively frequent tabletop 120 movement may nevertheless be desired for transport or storage.
(44) As seen in
(45) It should be noted that, since the battery 124 of this embodiment need not be removed frequently, the tabletop 120 could be secured in its flipped-down position in a semi-permanent manner. As such, the latch assembly 174 could be replaced by or supplemented with a fastener arrangement connecting the battery compartment lid 140 to the body 142. The fasteners could, for example, comprise screws (not shown) passing through tangs 181 extending downwardly from the front end of the lid 140.
(46) Many other changes and modifications could be made to the invention without departing from the spirit thereof.
(47) For example, the tabletop 20, 106 need not be pivotally supported on the base 16, 102 so long as it is selectively movable relative to the base 16, 102 so as to expose an access opening 60, 144 for the battery compartment 18, 104.
(48) The scope of these changes and modifications will become apparent from the appended claims.
