## Background
RELATED APPLICATION
The present application is a non-provisional patent application and claims priority benefit, with regard to all common subject matter, of earlier-filed U.S. provisional patent application titled “BATTERY HOLDER AND ISOLATION ASSEMBLY”, Ser. No. 61/829,785, filed May 31, 2013, incorporated by reference in its entirety into the present document.


BACKGROUND
Vehicles such as cars and boats typically include one or more batteries for storing and providing electrical power. These batteries often fail or have reduced performance due to excessive vibrations and shocks generated or transmitted by the vehicles. This is especially true for batteries used in boats, personal watercraft, all-terrain vehicles, and other vehicles that operate in rough water or uneven terrain. All types of batteries, and particularly high performance batteries used in marine applications, are expensive, difficult to replace, and difficult to safely dispose. Thus, prolonging their useful lives is highly desired.
Conventional battery holders such as battery cases secure their batteries to the vehicles but do not absorb vibrations and shocks transmitted or generated by the vehicles. Shock absorbing pads have been developed for placement under the batteries, but the batteries are no longer secured to the vehicles. Strapping the batteries to the vehicles or otherwise securing the batteries to the vehicles while they are on the shock absorbing pads results in the shock absorbing pads being ineffective because vibrations and shocks travel through the securing straps to the batteries.
SUMMARY
The present invention solves the above-described problems and provides a distinct advance in the art of battery holders. More particularly, the present invention provides a battery holder and isolation assembly that both secures a battery to a vehicle and mechanically isolates the battery from the vehicle.
A battery holder and isolation assembly constructed in accordance with an embodiment of the invention broadly includes a vehicle mounting plate, a lower battery containment plate, an upper battery containment plate, a number of spacer rods, and a number of shock absorbing elements.
The vehicle mounting plate is a corrosion resistant metal or plastic mounting plate including a number of fastener holes for securing the vehicle mounting plate to a surface of the vehicle and for securing the shock absorbing elements to the vehicle mounting plate.
The lower battery containment plate is a corrosion resistant metal or plastic mounting plate including an upper surface, a vertically extending lip, a number of fastener holes, and a number of spacer rod holes. The upper surface may include a recessed area for receiving a bottom portion of the battery therein. The vertically extending lip extends upward around the recessed area and retains the bottom portion of the battery in the recessed area. The fastener holes receive fasteners of the shock absorbing elements therethrough for securing the lower battery containment plate to the shock absorbing elements. The spacer rod holes of the lower battery containment plate are counterbore through-holes for receiving lower ends of the spacer rods therein.
The upper battery containment plate is a corrosion resistant metal or plastic mounting plate including a lower surface, a vertically extending lip, a number of spacer rod holes, and a number of terminal openings. The lower surface may include a recessed area for receiving a top portion of the battery. The vertically extending lip extends around the recessed area and retains the top portion of the battery in the recessed area. The spacer rod holes of the upper battery containment plate receive upper spacer rod fasteners therethrough for connecting top ends of the spacer rods to the upper battery containment plate.
The spacer rods are elongated metal rods, bolts, straps, or other fasteners. The spacer rods are fastened to the lower battery containment plate and the upper battery containment plate via the spacer rod holes. The spacer rods secure the battery between the lower battery containment plate and the upper battery containment plate.
The shock absorbing elements may be Sorbothane® Stud Mounts, rubber, or other suitable shock-absorbing components. The shock absorbing elements each include a shock absorption portion, a lower fastener, and an upper fastener.

Turning now to the drawing figures, a battery holder 10 constructed in accordance with an embodiment of the present invention is illustrated. The battery holder 10 broadly comprises a vehicle mounting plate 12, a lower battery containment plate 14, an upper battery containment plate 16 or other securement component, a number of spacer rods 18, and a number of shock absorbing elements 20.
The vehicle mounting plate 12 supports the weight of a battery 22 and the other components of the battery holder 10 on a surface or mounting component of the vehicle and may be formed of corrosion resistant billet aluminum, molded plastic, or any other suitable material. The vehicle mounting plate 12 includes a plurality of fastener holes 24 for receiving vehicle mounting fasteners 26 therethrough, as shown in FIGS. 3 and 4. Alternatively, the vehicle mounting plate 12 may be secured to the vehicle via straps, clamps, or other fasteners. The vehicle mounting plate 12 also includes additional fastener holes 28 for receiving shock absorber fasteners therethrough. It will be understood that an alternative configuration of the invention may not use a vehicle mounting plate with the shock absorbing fasteners being secured directly to the vehicle.
The lower battery containment plate 14 supports the weight of the battery 22 on the shock absorbing elements 20 and may be formed of corrosion resistant billet aluminum, molded plastic, or any other suitable material. The lower battery containment plate 14 includes an upper surface 30, a vertically extending lip 32, a plurality of shock absorber fastener holes 34, and a plurality of spacer rod holes 36, as shown in FIGS. 2-4. The upper surface 30 includes a recessed area 38 for positioning a bottom portion of the battery 22 therein. The lip 32 retains the bottom portion of the battery 22 and any leaking battery liquid in the recessed area 38. The lip 32 extends around the recessed area 38 and extends upward from the recessed area approximately 1⁄8th of an inch to 1 inch. The shock absorber fastener holes 34 receive shock absorber fasteners therethrough and are spaced from each other in line with the shock absorbing elements 20. The shock absorber fastener holes 34 may be countersunk or counterbore for preventing battery liquid from leaking therethrough when shock absorber fasteners are secured therein. The spacer rod holes 36 are counterbore through-holes for receiving lower ends of the spacer rods 18 in the wider counterbore portion and for receiving lower spacer rod fasteners 40 through the narrow through-hole portion. The lower spacer rod fasteners 40 are helical-threaded bolts having a male or female hex head, square head, or any other suitable head. The male hex head allows the lower spacer rod fasteners 40 to be tightened via a standard wrench, hex key, or other tool, which reduces the clearance necessary below the spacer rod holes 36. It will be understood that the counterbore feature of the spacer rod holes 36 may be employed in the spacer rod holes of the upper battery containment plate (described below) instead.
The upper battery containment plate 16 covers the top of the battery 22 and may be formed of corrosion resistant billet aluminum, molded plastic, or any other suitable material. The upper battery containment plate 16 includes a lower surface 42, a vertically extending lip 44, a plurality of spacer rod holes 46, and one or more terminal openings 48. The lower surface 42 includes a recessed area 50 for receiving a top portion of the battery 22. The lip 44 retains the battery 22 in the recessed area 50 under the upper battery containment plate 16. The lip 44 extends around the recessed area 50 and extends downward from the recessed area approximately 1⁄8th of an inch to 1 inch. The spacer rod holes 46 receive upper spacer rod fasteners 52 therethrough and are aligned with the spacer rod holes 36 of the lower battery containment plate 14. The spacer rod holes 46 may each be positioned in a recessed area of the upper battery containment plate so that the upper spacer rod fasteners 52 do not extend above an upper surface of the upper battery containment plate 16. The upper spacer rod fasteners 52 are helical-threaded bolts having a male or female hex head, square head, or any other suitable head. The head may also be a round head, flat head, button head, or other smooth head for providing an attractive look to the battery holder 10 and for minimizing the chance of the upper spacer rod fasteners 52 inadvertently becoming loose. The terminal opening 48 provides access to the battery terminals and/or the filler caps of the battery 22 and extends through the recessed area 50 of the lower surface 42. The terminal opening 48 may be a regular shape such as a slot or may be an irregular shape for providing access to terminals and/or filler caps of different sized batteries. As an alternative to the upper battery containment plate 16, a securement component such as a covering, a lid, a case, or one or more straps, cords, ropes, chains, clamps, brackets, U-shaped bolts, side plates, or other elements may be used for securing the battery 22 to the lower battery containment plate 14.
The spacer rods 18 retain the upper battery containment plate 16 over the battery 22 and are elongated metal rods, bolts, or other fasteners. The spacer rods 18 extend from the spacer rod holes 36 of the lower containment plate 14 to the spacer rod holes 46 of the upper containment plate 16. In one embodiment, the battery holder 10 includes two spacer rods 18 with one rod extending near each end of the battery holder 10.
The shock absorbing elements 20 isolate the battery 22 from vibrations and shocks generated or transmitted by the vehicle and may be disc-shaped or any other suitable shape. The shock absorbing elements 20 may be Sorbothane® Stud Mounts, rubber, or other suitable component. The shock absorbing elements 20 are positioned between the vehicle mounting plate 12 and the lower containment plate 14 in line with the fastener holes 24 of the vehicle mounting plate 12 and the fastener holes 34 of the lower battery containment plate 14, as shown in FIG. 5. In one embodiment, the battery holder 10 includes six shock absorbing elements 20 with four elements positioned in a rectangular array and two elements spaced on opposite sides of the rectangular array. The shock absorbing elements 20 include a shock absorption portion 54, a lower shock absorber fastener 56, and an upper shock absorber fastener 58. The shock absorption portion 54 absorbs the vibrations and shocks generated or transmitted by the vehicle and may be formed of Sorbothane® material, rubber, or other suitable material. The lower fastener 56 may be a male or female-type threaded fastener or any other suitable fastener embedded into the bottom of the shock absorption portion 54. The upper fastener 58 may be a female or male-type threaded fastener embedded into the top of the shock absorption portion 54 and extending upwards. The lower fastener 56 and the upper fastener 58 are separated from each other by the shock absorption portion 54 so that vibrations and shocks are not transmitted through the fasteners 56, 58.
The above-described battery holder 10 may be assembled as follows: first, the vehicle mounting plate 12 is positioned on a battery mounting surface or bracket of the vehicle and fastened to the surface or bracket via the vehicle mounting fasteners 26. The shock absorbing elements are then fastened to the vehicle mounting plate 12 via the lower shock absorber fasteners 56. The lower battery containment plate 14 is then fastened to the shock absorbing elements 20 via the upper shock absorber fasteners 58 with the recessed area 38 facing upward and with the lower spacer rod fasteners 40 inserted upward into the narrow portion of the counterbore spacer rod holes 36. In some embodiments, the lower spacer rod fasteners 40 must be inserted into the spacer rod holes 36 before the lower battery containment plate 14 is fastened to the shock absorbing elements 20 because there is not enough clearance between the lower battery containment plate and the vehicle mounting plate 12 when assembled. The battery 22 is then placed in the recessed area 38 of the lower battery containment plate 14. The spacer rods 18 are then fastened to the upper battery containment plate 16 via the upper spacer rod fasteners 52. The upper battery containment plate 16 is then placed over the top of the battery 22 with the spacer rods 18 extending downward and with the recessed area 50 of the upper battery containment plate 16 facing downward so that the upper portion of the battery 22 is received in the recessed area 50. The terminals of the battery will also extend upward through the terminal opening 48. The lower ends of the spacer rods 18 are also inserted into the counterbore portion of the spacer rod holes 36 with the ends of the spacer rods 18 fitting over the ends of the lower spacer rod fasteners 40 that are extending upward through the spacer rod holes. The lower spacer rod fasteners 40 are then turned using a conventional wrench, hex key, or other tool so that the helical threads of the lower spacer rod fasteners 40 draw the lower ends of the spacer rods 18 further into the counterbore portion of the spacer rod holes 36. The lower spacer rod fasteners 40 are tightened until the upper battery containment plate 16 is snug against the top of the battery 22. Depending on the height of the battery 22, the lower ends of the spacer rods 18 may extend only partially into the counterbore portion of the spacer rod holes 36 when the lower spacer rod fasteners 40 are fully tightened.
In one embodiment of the invention, the vehicle mounting plate 12, the lower battery containment plate 14, and the shock absorbing elements 20 are pre-assembled into a shock base 60. The shock base 60 is mounted to the vehicle surface. The battery 22 is then placed on the lower battery containment plate 14 and the upper battery containment plate 16 is attached over the battery 22 via the spacer rods 18 as described above.
In another embodiment of the invention, a securement component is used instead of the upper battery containment plate 16 to secure the battery 22 to the lower battery containment plate 14. For example, a strap could be weaved through two slots in the lower battery containment plate 14 and cinched down over the battery 22. As another example, a case lid could be placed over the battery and screwed or snapped onto the lower battery containment plate 14.
In another embodiment of the invention, the shock absorbing elements 20 may be secured directly to the vehicle without the use of a vehicle mounting plate 12.
When the battery holder 10 is assembled, the lower battery containment plate 14 and the upper battery containment plate 16 (or securement component) secure the battery 22 between them, and the shock absorbing elements 20 mechanically isolate the battery 22 from the vehicle. Because the lower and upper shock absorber fasteners 56, 58 are not connected to each other, the only physical connection between the battery containment plates 14, 16 and the vehicle mounting plate 12 is the shock absorption portion 54. This prevents vibrations and shocks from passing through the fasteners 56, 58 to the battery 22. Specifically, when the shock absorbing elements 20 are subjected to a compressive force, they compress inwardly from the top to bottom and bulge outwardly along their radial sidewalls to absorb and dampen the force. Similarly, when the shock absorbing elements 20 are subjected to a tensional force, they stretch outwardly from top to bottom and compress inwardly along their radial sidewalls to absorb or dampen the force.
The above-described battery holder 10 provides several advantages over conventional battery holders. For example, the battery holder 10 both secures the battery 22 to the vehicle and protects the battery 22 from vibrations and shocks. The terminal opening of the upper battery containment plate 16 allows the terminals and fill caps of batteries of different sizes to be accessed. The counterbore spacer rod holes 36 allow for the spacer rods 18 to be drawn into the counterbore portion of the spacer rod holes 36 to a depth corresponding to the height of the battery 22. This allows for the battery holder 10 to secure batteries of different heights and obviates the need to use different battery holders for different sized batteries.
Although the invention has been described with reference to the embodiments illustrated in the attached drawing figures, it is noted that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the claims.
