TRAY ASSEMBLIES FOR ACID DRIVER BATTERY SEALED AND VEHICLES MOVED BY ENERGY USING SUCH BATTERY TRAY ASSEMBLIES Mr. GORDON C. BECKLEY, of American nationality, with address at 977 Acorn Lane West, City of Chicago, State of Illinois , United States of America, inventor, assigns, sells and transfers to GNB BATTERY COMPANY, a North American company, domiciled at 8229 Par view Boulevard, city of Lombard, State of Illinois, United States of America, all rights in the invention that in The following is described: Field of the Invention This invention relates to lead acid batteries and more particularly, battery tray assemblies for sealed and maintenance-free lead acid batteries used in vehicles that move by electric power. Description of the Prior Art Pallet receptacles are very commonly used in shipping and storage. Such pallet shelters, also referred to by motorized trucks or class 3 trucks, are in essence a pallet lift which is operated by a person walking behind the forklift. The pallet housing typically includes a frame on which the transmission mechanisms and elevators and other operational components are mounted. The operational components are usually enclosed within a sheet metal cover. A steering handle is attached to the frame, and controlled for the operation of the pallet housing components that are typically mounted on that handle. Pallet shelters are usually energized with electricity. In light duty pallet housing, electrical power is most commonly useful supplied by four batteries flooded with lead acid. In this way, the shelters for light work platforms incorporate an assembly for mounting batteries on the pallet housing, as well as a charger which can be used to recharge the batteries. To date assemblies for the assembly of batteries for housings of light work platforms have been relatively complicated and expensive to manufacture and assemble. For example, a very common design is characterized by pivoting battery shelves. These so-called "swing" designs include a lower shelf mounted on the pallet housing. The lower shelf supports two batteries. Two additional shelves are pivotally mounted slightly off center and above the bottom shelf. Each of the upper shelves supports a battery and the upper shelves can be pivoted away from the housing to provide better access to the lower batteries, for example, so that the batteries can be moistened. A charger is screwed on or around the vertical center line between the batteries. Battery shelves typically have flanges to restrict the horizontal movement of batteries, since otherwise, batteries are held in place by their own weight or by plastic straps. A cover or cover is then mounted on the pallet housing on the batteries to avoid accidental contact with or damage to the batteries and the charger. However, there are several disadvantages with outward swing designs. First, they use flooded batteries which must be moistened frequently. If the flooded batteries are not properly maintained, and often are not, the battery may fail prematurely. While outward swing designs can obviously accommodate sealed lead acid batteries that do not require maintenance, the design itself is no more difficult and expensive to build and assemble. For example, outward swing designs incorporate a relatively large number of separate parts, such as shelves, hinges, brackets, circuitry, and the cover or lid. The relatively large number of parts increases the manufacturing cost of swing out designs. In addition, many of these components can be mounted separately. For example, the bottom shelf, the swing out shelves, and the magazine are usually bolted separately to the pallet housing or other components of the battery assembly assembly. The batteries then have to be installed and the battery connections made. Finally the energy packing lid is secured to the pallet housing, usually by means of plates or bolts, on the batteries and the assembly assembly. Even without the "swing out" feature, however, conventional battery assembly assemblies are necessarily complicated. The operations necessary to assemble the battery supports and to install the batteries are typically performed by the EM operator of the pallet housing at a relatively higher assembly cost. In addition, when pallet housing is in service in some designs the charger is accessible only by removing the lid. This is an inconvenience, and as time passes, the lid may be misplaced and the pallet housing used with the batteries may expose the "live" connections. Some covers incorporate a hinged door that allows access to the charger through the lid, but a hinged access door increases the complexity and cost of the lid. In addition, the plastic tapes used to secure the batteries in some designs are often removed or broken during the service life of the batteries. The operation of a pallet housing when its batteries are not adequately secured creates an obvious danger. An objective of the present invention, therefore, is to provide battery tray assemblies in which the batteries and the charger can be safely mounted in a manner that minimizes accidental contact with or damage to the batteries and charger , but also be easier and economically manufactured, assembled and installed. A related and more specific goal is to provide such tray assemblies with a minimum number of parts that require less effort and expense to assemble. Another object of the present invention is to provide such battery tray assemblies for sealed lead acid batteries, thereby eliminating the need for batteries that become wet once the tray assembly is put into service. It is an additional objective to provide such battery tray assemblies that allow easy access to the charger controls and power cord. Still another objective is to provide battery tray assemblies where all the aforementioned advantages are realized, and to provide pallet accommodations that use those battery tray assemblies. These and other objects and advantages of the invention will be apparent to those skilled in the art upon reading the following description and referring to the drawings.

Summary of the Invention The present invention provides a tray assembly for sealed lead acid batteries for electric vehicles. The battery tray assembly comprises a battery tray having a tray base adapted to support one or more sealed lead acid batteries. The battery tray has three protruding tray walls, consisting of two side walls and a front wall which are attached to the base of the tray, a tray top attached to the walls of the protruding tray and one or more dividing walls. The base of the tray, the side walls, the front wall, the upper part of the tray, and the dividing wall define one or more compartments adapted to receive batteries and a compartment adapted to receive a battery charger. The battery tray has a generally open backrest which provides access to charge batteries inside the battery compartments and to charge a charger inside the charger compartment. Otherwise, the battery and charger compartments are substantially enclosed by the battery tray. The battery tray assembly further comprises a battery charger mounted in the battery compartment, and two or more sealed lead acid batteries supported in the battery compartments. The batteries are electrically connected together to provide positive and negative terminals. In this way, the battery assemblies of the present invention incorporate in a single unit, batteries needed to energize electric vehicles and a charger to maintain the charge of those batteries. The novel battery tray assemblies, as they will become apparent from the discussion that follows, are also easier and economically manufactured, assembled and installed. In particular, they can be manufactured and assembled by a battery manufacturer and installed as a unit by the EM operator of the vehicle. The new battery tray assemblies, when installed in a vehicle, require minimal maintenance as opposed to charging the batteries. The batteries are mounted securely there in such a way that throughout their service life, they remain without accidental contact with vehicle operators and are protected from damage caused by battery discharge or other accidental impacts.

Detailed Description of the Invention Figure 1 illustrates a preferred embodiment 10 of the battery tray assemblies of the present invention. As shown there, the battery tray assembly 10 comprises a battery tray 20, a charger 30, and four batteries 40a, 40b 40c, and 40d (collectively 40). The batteries 40 are preferably sealed, valve regulated and lead acid batteries, which require no maintenance, and four such 12-volt batteries will provide sufficient power for light duty pallet trucks. As will be appreciated from the description that follows, however, the battery tray assemblies of the present invention may incorporate more or little more than 4 batteries depending on the power requirements of the vehicle in which the tray assemblies battery will be installed. The batteries 40 are electrically interconnected via suitable connectors 41 and are in turn connected to a power supply cable 42 by means of which energy can be supplied to a motor vehicle. The cables 42 are located centrally in the assembly so that they more easily reach a vehicle power receptacle regardless of the side on which the receptacle is placed. The batteries 40 are also connected to the charger 30 by suitable connections (not shown) so that the batteries 40 can be recharged, and any charger suitable for such purposes can be used in the present invention. The electrical connections between the batteries and the charger can be made using any of the desired connectors appropriate for such purposes. Many suitable connectors are known. The use of various conductor-coated copper cables and connectors are known and have been used. Burning connectors, such as those used with batteries flooded with lead acid, can also be used to interconnect batteries, if desired. Similarly, any appropriate power cable can be used to supply power to the motor vehicle, and many such cables are known. The battery tray assemblies of the present invention, as denoted, include a battery tray. The battery tray is adapted to accommodate and support the charger and batteries in a safe and secure manner, while at the same time allowing the easier and more economical manufacture of the battery assembly tray and the installation of the entire unit. At this end, the battery tray includes a tray base adapted to support one or more sealed lead acid batteries. The battery tray also includes 3 walls of protruding trays attached to the base of the tray, the projecting tray walls consist of 2 side walls and a front wall. An upper part of the tray is attached to the protruding tray walls, and the battery tray is provided with one or more partition walls as well. The base of the tray, the side walls, the front wall, the top of the tray and the dividing walls define one or more compartments for receiving a battery charger. For example, as can best be seen in Figure 2, the battery tray assembly 10 includes a base 21. Two side walls 22a and 22b (collectively 22) and a front wall 23 are attached to the base 21, and a part upper 24 are attached to the side walls 22 and the front wall 23. A vertical divider wall 25 extends between the base of the tray 21 and the roof 24. A horizontal divider wall or shelf 26 extends between the vertical divider wall 25 and the left side wall 22b. It is to be understood that Figure 2 is a perspective view taken from the rear of the battery tray assembly 10. Also the terms "rear", "front", "right", "left", and the like are used by convenience and relate to the orientation of the battery tray assembly 10 when installed, as described below, in a motor vehicle such as a pallet housing for light work. The battery tray 20 defines several compartments adapted to receive and support the charger 30, the batteries 40 and other components of the battery tray assembly 10. More specifically, the base 21, the right side wall 22a, the front wall 23, the upper wall 24, and vertical dividing wall 25 define a compartment in which the magazine can be received. The base 21, the left side wall 22b, the front wall 23, the upper wall 24, the dividing wall 25, and the shelf 26 define two battery compartments in each of which two batteries can be received. The side walls 22 preferably have openings 27 which facilitate the housing and handling of the battery tray assembly 10. One of the protruding tray walls defining the area of the magazine, according to another preferred feature of the present invention, is provided. with an opening through which the controls for the charger can be accessed. For example, the right side wall 22a of the battery tray assembly 10 is provided with an opening 28, as best seen in Figure 1. It will be appreciated that access to the controls of the magazine can be provided by a hinged door. Such doors offer certain advantages, but increase the cost of manufacturing and assembling the battery tray. The right side wall 22a also has a number of ventilation openings 29 by means of which circulation of the air around the charger 30 is facilitated. The precise configuration of the openings 27, 28 and 29, however, are a matter of preference, and any suitable configuration for their respective purposes can be used. The battery assembly can be made of any suitable material. Due to the weight requirements involved, it is desirable to use, for example, sheets of hot rolled steel or commercial grade soft rolled steel having thicknesses of about 0.080 to 0.120 inches. The sheet metal can be bent, stamped and otherwise worked in the desired configuration by conventional metal working machinery. To minimize some corrosion problems in the unlikely event of any leakage or the like, the components may be coated with an epoxy liquid or epoxy powder material. Suitable epoxy materials are well known and have been used in this field for general purposes. It may also be desirable to mold the components of the tray from an appropriate structural polymer, such as polyvinyl chloride or foamed polypropylene. According to another aspect of the preferred embodiment of the present invention, the battery tray uses the minimum number of components which are designed in a way to facilitate the manufacture of the battery tray. In this regard, as can best be seen in Figure 9, the base 21, the front wall 23, and the top 24 are made of a single sheet of metal. The side walls 22 and dividing walls are manufactured separately, for a total of five sheet metal components. These five components are preferably welded together by conventional equipment, but rims, openings and the like can be provided so that the components can be joined by other suitable fasteners such as screws and nuts and bolts. It will be appreciated, therefore, that the battery tray itself, being made of a relatively minimal number of relatively uncomplicated components, is made easier and more economically. In accordance with the present invention, as can be seen in Figures 1-9, the back of the tray is generally open and the generally open back facilitates assembly of the battery tray assembly by providing easy access for charging batteries and chargers in their respective compartments. More specifically, the open back of the battery tray 20 allows the batteries 40 to be easily loaded onto the base 21 and the shelf 26. The distance between the base 21 and the shelf 26 and between the shelf 26 and the top 24 is preferably slightly larger than the height of the batteries 40 to facilitate the charges of the batteries 40 the installation of the connections 41, the connection of the power cord 42 and the assembly of other components as described below. Lead acid batteries, such as batteries 40, are very heavy. In this way, they will not be easily moved by accidental contact with the battery or the tray. Preferably, however, the novel battery tray assemblies are adapted to securely mount the batteries in place once they are charged into the battery compartments. For example, the base of the tray 21 and the assembly 26 preferably have a flange projecting upwards from its trailing edges. The depth of the base of the tray 21 and the shelf 26 is substantially equal to the width of the batteries 40. This is the depth of the base 21 and the shelf 26 is such that the batteries 40 can be placed on them with relative ease. Once the batteries 40 are in place, however, the ridges serve to prevent significant movement of the backs of the batteries back and forth on the base 21 and the shelf 26. It will be appreciated, of course, that the The rim, although shown to be continuous and relatively short in height, may have other configurations or may be replaced by other appropriate restrictor means, such as tabs, brackets, fasteners, and the like. In other preferred aspects, the width of the compartments of the battery is coordinated and other means are provided to optionally restrict the movement of the batteries once they are loaded into the battery tray. For example, the battery tray assembly is provided with bracket 50 and 53, one of each being mounted within each battery compartment. The brackets 50, shown in detail in Figure 10, are L-shaped. A vertical portion 51 of the bracket 50 is welded to the side wall 22b in such a position that a horizontal portion 52 of the brackets 50 rests on or slightly above the batteries 40b, 40d to restrict the upward movement of these, as can be seen in figure 1. Such brackets, however, can be mounted by any suitable means. For example, a bracket 58, shown in detail in Figure 11, which is identical to the bracket 50 except for an opening 49, can be used and mounted on the side wall 22b by screws or nuts and bolts. The brackets 53, shown in detail in Figure 12, are mounted on the divider wall 25. The brackets 53 can be mounted by any suitable means, but as will become apparent in the discussion in the manner in which the loader 30 is preferably mounted, the brackets 53 are preferably mounted, one in each battery compartment, on the partition walls 25 by bolts which extend through suitable openings in a first vertical portion 54 of the brackets 53 and of the divider wall 25. brackets 53 are mounted at a height equal to or slightly greater than the height of the batteries 40a, 40c so that the end of a first horizontal portion 55 of the brackets 53 rests on or slightly above the upper surface of the batteries 40a, 40c for restrict the batteries 40a, 40c of the upward movement in a manner analogous to the brackets 50, as best shown in Figure 13. A second portion vertical 56 of the brackets 53 rests against or is slightly spaced from the side wall of the batteries 40a, 40c so that the batteries 40a, 40c are spaced a short, predetermined distance away from the vertical divider wall 25. A second horizontal portion 57 of the brackets 53 reinforce the separation. The length of the battery compartment is coordinated such that it is substantially equal to the combined length of both batteries 40 and the predetermined distance separating the batteries 40a, 40c and the vertical divider wall 25. Thus, the brackets 53 and the side wall 22b serve to restrict the side-to-side movement of the batteries 40 on the base 21 and the shelf 26. The brackets, such as the brackets 53, They are preferred not only because they help secure the batteries inside the battery tray, but also because they create an air gap between the vertical divider wall and the batteries through which air can circulate. Such air circulation can dissipate the heat generated by both the battery and the charger when the battery is charged. However, it is expected that the battery tray assemblies without such separation will provide satisfactory performance because the metal from which the tray is made also tends to dissipate the heat of the charger and the battery. If no separation is to be provided between the battery and the vertical divider wall, a bracket may be provided which simply restricts the battery from upward movement, such as the bracket 48 shown in Figure 13. The length of the battery compartment could preferably be be substantially equal to the combined length of two batteries 40 so that the vertical divider wall 25 and the side wall 22b serve to restrict the side to side movement of the battery 40. In addition, it will be appreciated that the battery mounting assemblies of the present invention can be adapted to incorporate different sets of brackets mounted in different locations so that a single tray can accommodate batteries having different sizes or configuration of containers. For example, by selectively using brackets 53 with bracket 58, the battery tray assembly 10 can accommodate and secure batteries having containers of different lengths. The same compatibility can be provided by using different sets of brackets 53 that differ in the length of their horizontal portions 55 and 57. Similarly, multiple holes for screws, or an oval-shaped screw hole as incorporated in brackets 43 and 48, can be provided in the brackets or in the tray to allow the mounting of the brackets at different heights so that the tray can accommodate batteries of different heights. There is, therefore, a variety of ways in which the brackets can be configured and various configurations thereof, between which the brackets can be mounted on the battery tray and for which the battery tray must be adapted to accept and Secure batteries that have different sizes. As noted above, the generally open back of the built-in tray within the novel battery tray assemblies also facilitates the mounting of the magazine and the magazine compartment. That is, the magazine can be placed in its place through the open back and mounted in the magazine compartment, for example, by means of bolts and nuts. Preferably as in the battery tray assembly 10 the same bolts and nuts that were used to secure the brackets 53 to the vertical divider wall 25 are used to secure the magazine 30. It will be appreciated, however, that the magazine can be mounted within the Charger compartment by screws, tapes, fasteners, or any other suitable means. According to another preferred feature of the present invention it will be appreciated that the upper portion of the magazine compartment is not occupied by the magazine 30. This portion of the magazine compartment can be used as a storage area for the charging energy cord ( not shown), and the energy cord can be removed or replaced through the opening 28 which is adjacent thereto. In addition, a "dead" male connector 31, that is, a male connector that is not electrically connected, can be mounted on the charger or inside the charger compartment so that the power cord 42, when it is not being used, it can be secured to it. It will be appreciated that the specific functions of the tray used in the present invention is a matter of choice dictated in large part by the dimensions of the batteries to be accommodated and the space limitations imposed by the vehicle on which the tray assembly Battery will be installed. However, in general, the dimensions must be coordinated to allow the batteries that are to be tucked into place through the open back parts interconnected with sufficient ease. At this time, the dimensions of the battery compartments and the configuration and location of the brackets must be coordinated so that the batteries are immobilized, if not completely at least to the point where it is very difficult for the batteries to accidentally fall out of the battery. tray. The battery tray assemblies of the present invention can be used for energized motor vehicles such as a light duty pallet housing 60 shown in FIG. 14. Most importantly, the novel battery tray assemblies can be assembled as a unit by a battery manufacturer and then installed as a unit by the EM operator of the vehicle. This is a more economical method of installation assembly compared to the installation of components separated by the EM operator of the vehicle. The pallet housing 60 includes lifting tabs 61 projecting from the front of the housing and several elevators, impellers, and other operational components (not shown) which are mounted towards their rear under a cover 62. The operational components are controlled by suitable controls mounted on a handle 63 extending from the back of the housing and which can be manipulated by a vehicle operator. The lid of the components 62 substantially encloses the operational components and together with a distribution plate 64 extending around the lower portion of the pallet housing 60 defines a depression 65 within which the battery tray assemblies 10 can be installed. Given the relative depth of the depression 65 and the weight of the battery tray assembly 10, it might not be necessary to otherwise secure the battery tray assembly 10 with the pallet housing 60. However, it is preferable especially when the housing of pallets has a hollow depression or no other support surface, that the battery tray assembly can be secured in some way, for example by bolts and nuts with the vehicle. As can be seen in Figure 14, the battery tray assembly 10 is installed against or closely adjacent to the cover of the components 62. Thus, regardless of the fact that the battery tray 20 has an open back, due to that the battery compartment and the magazine compartment are otherwise substantially enclosed, the battery tray assembly provides both protection for and necessary access to the components of the assembly, ie via the opening 28 of the magazine 30 and its cord of energy are easily accessible. At this time the magazine 30 is enclosed in the magazine compartment by the adjacent face of the cover of the components 62 and protected against damage caused by objects that could otherwise be impacted during service. The batteries 40 are similarly enclosed, thus avoiding damage to the battery and damage to vehicle operators who could otherwise be injured by the exposed batteries. According to another preferred aspect of the invention, it should be noted, especially by reference to FIG. 2, that the depth of the lid of the tray 24 is greater than the depth of the base of the tray 21 and the shelf 26. When the assembly of the battery tray 10 is installed against the cover 62 of components of the pallet housing 60, therefore, the internal opening is created between the cover of the components 62 and the base of the tray 21 and the shelf 26. This opening allows space for the connection of cables 41 and allows the circulation of air through the various compartments. From the foregoing, therefore, it can be seen that the battery tray assemblies of the subject invention offer significant advantages to battery manufacturers, to vehicle EM operators, to vehicle operators. As you can see, the innovative battery trays have relatively fewer parts and those parts have relatively simple designs. Thus, battery trays are easily manufactured. Because the battery trays have the back open, the batteries and charger are easily charged and assembled. However, the same battery tray can be made to accommodate batteries of various sizes by means of the use of appropriate supports. The new battery tray assemblies also offer several advantages over previous designs of the technique which must be assembled by means of the EM operator of the OEM vehicle from various parts. The OE operator of the vehicle can install the parts of the battery tray as a unit with very little effort. Once installed, the parts of the battery tray provide the vehicle with all the components related to the power. Vehicle operators also realize significant advantages of the new battery tray assemblies. For example, soaking the batteries is not necessary. The only periodic maintenance is to charge the batteries, and charging them is easy because the controls and power cables are immediately accessible. At the same time, operators are protected from the risks of exposing battery connections. The trays for batteries, although they have the back open, which facilitates the assembly of the unit, are "enclosed" by means of the cover or cover of vehicle components. The tray does not have to be removed to charge the battery and, in fact, can not be removed without removing the batteries as well. Thus, there is no risk that the vehicle will be operated with batteries in sight. This invention has been disclosed and discussed primarily in terms of specification incorporation. It is not intended, however, to be limited to that. For example, the battery tray could be provided with an additional vertical divider wall such that the magazine compartment is placed in the center of the tray between the battery compartments. Other modifications and incorporations will be evident for the worker in the technique.

The base of the tray, the side walls, the front wall, the top of the tray, and the dividing wall define one or more compartments adapted to receive batteries and a compartment adapted to receive a battery changer. The battery tray generally has an open back which provides access to change batteries inside the battery compartments and to charge a charger inside the charger compartment. Otherwise, the battery and charger compartments are substantially closed by the battery tray. The battery tray assembly further comprises a battery charger mounted in the charger compartment, and two or more sealed lead acid batteries, supported in the battery compartments. The batteries are electrically connected together to provide positive and negative terminals.
