Description

PATENT docket no. 025493-609900 Electronic Torque Wrench with Interchangeable Battery Technical Field of the Invention The present invention relates generally to electronic torque wrenches. More particularly, the present invention relates to electronic torque wrenches with a battery receptacle adapted to receive a unitary battery pack or a battery tray that can hold conventional dry cell-type batteries. Background of the Invention Electronic torque wrenches are a common tool used with, for example, automotive repair. Electronic torque wrenches measure various parameters of torque applied by the tool to work pieces, such as bolts or nuts, to ensure a proper torqueing operation is performed. For example, an electronic torque wrench can measure the amount of torque or the angle of rotation applied by the tool to a bolt. Some electronic torque wrenches can provide a visual or tactile indication to the user that the proper torqueing operation has been performed when, for example, a predetermined amount of torque or angular rotation has been applied to a work piece. Conventional electronic torque wrenches are typically battery powered. Some electronic torque wrenches require a unitary battery pack that is specially designed for either the model of electronic torque wrench or for multiple power tools manufactured by the same manufacturer, thus limiting their operability with other types of tools. Other electronic torque wrenches that .. directly receive conventional batteries, such as AA, AAA, or 9 V batteries. Summary of the Invention The present invention broadly comprises an electronic torque wrench with a battery receptacle adapted to receive either (1) a unitary battery pack; or (2) a battery tray containing separate batteries inside. The batteries received by the battery tray can be conventional dry cell- 1 Date recue/Date Received 2020-08-28 type batteries such as AA, AAA, or 9 V batteries, for example. The battery tray and unitary battery can be constructed of a similar geometry to fit within the battery receptacle. For example, the battery tray and unitary pack can include an outwardly-extending protrusion that is received within a groove of the battery receptacle to permit only the specially- designed battery tray and pack to releasably couple with the receptacle. In particular, the present invention broadly comprises a tool including a head extending from a handle, and a base coupled to the head and dimensioned to receive either a battery tray or a unitary battery pack. The battery tray includes receiving areas dimensioned to receive conventional batteries within the receiving areas, a tray interface that releasably couples with the base, and tray terminals that electrically connect the battery tray to the base. The unitary battery pack includes a dedicated battery, a battery interface that releasably couples with the base, and battery pack terminals that electrically connect the battery pack to the base. The present invention further broadly comprises a tool including a drive that applies torque to work pieces, and a base coupled to the drive and receiving a battery. The battery is interchangeable between a battery tray and a unitary battery. The battery tray includes a receiving area dimensioned to receive conventional batteries therein, a tray interface that releasably couples with the base, and tray terminals that electrically connect the battery tray to the base. The unitary battery pack including a dedicated battery, a battery interface that releasably couples with the base, and battery pack terminals that electrically connect the battery pack to the base.

Detailed Description of the Embodiments While this invention is susceptible of embodiments in many different forms, there is shown in the drawings, and will herein be described in detail, a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an 3 Date recue/Date Received 2020-08-28 exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to embodiments illustrated. As used herein, the term "present invention" is not intended to limit the scope of the claimed invention and is instead a term used to discuss exemplary embodiments of the invention for explanatory purposes only. The present invention broadly comprises an electronic torque wrench with a battery receptacle capable of receiving either a unitary battery pack or a battery tray containing separate batteries inside. The battery tray can receive conventional batteries, such as, for example, one or more AA, AAA, C, D or 9-volt sized batteries. Further, the battery tray and unitary battery can have a similar geometry to fit within the same battery receptacle. In some embodiments, the battery tray and unitary pack can include an outwardly-extending protrusion that is received within a groove of the battery receptacle to permit only the specially- designed battery tray and pack to couple with the receptacle. Referring to FIGs. 1-4, a tool 100, such as an electronic torque wrench, can include a head 105 extending from a handle 110 and a drive 115 to couple with a socket (not shown) to apply torque to a work piece. The handle 110 can include a display 120 and keypad 125 to receive input from the user of the tool 100 and display outputs to the user. For example, the user can input a desired torqueing parameter to be reached by the tool 100 by using the keypad 125 and, when the desired torque or other parameter is reached, the display 120 can notify the user. In an embodiment, a separate indicator can be located on the tool 100 in any location to provide a tactile or visual indication when the tool 100 reaches the desired torqueing parameter. The tool 100 can further include a base 130 releasably coupled to a battery pack 135 via an interface 140. The battery pack 135 can include a tower 143 that inserts into a corresponding cavity within the base 130, and one or more latches 146 that are spring-biased to a closed 4 Date recue/Date Received 2020-08-28 position. When the battery pack 135 is inserted into the base 130, the latch 146 can be pushed open and then close under the bias of the spring to couple with the anchor 147, thereby removably coupling the battery pack 135 to the tool 100. When the user desires to remove the battery pack 135, for example to charge the battery pack 135, the user can push inwardly on the latch 146 to remove the bias force applied against the anchor 147 and pull the battery pack 135 axially outwardly. As shown, the battery pack 135 is a unitary battery pack, meaning it includes a dedicated battery and does not require insertion of additional batteries, such as required by the battery tray, discussed below in more detail. FIGs. 5-6 illustrate a battery tray 535 inserted into the base 130, and FIGs. 7-8 illustrate .. the battery tray 535 itself. As shown, the battery tray 535 can include a tower 543 and latches 546 that couple with an anchor 147, similar to the embodiment of FIGs. 1-4. The battery tray 535 can include one or more receiving areas 549 that receive conventional batteries such as, for example, AA, AAA, C, D or 9-volt sized batteries. In this manner, the battery tray 535 can receive conventional batteries and releasably couple with and power the tool 100 in the same manner that the battery pack 135 of FIGs. 1-4 releasably couples with and powers the tool 100. As shown in FIGs. 7-8, the battery tray 535 can have generally the same geometry as the battery pack 135 and can therefore be insertable into the base 130 of the tool 100 in the same mechanical and electrical manner as the battery pack 135. For example, the battery tray 535 can include terminals 552 that electrically couple to a power circuit of the tool 100, and a protrusion 556 that cooperatively engages a corresponding groove 559 within the tool 100. For example, the protrusion 556 can extend axially along the battery tray 535 and insert into a corresponding axially-extending groove 559 within the base 130 of the tool 100. In this manner, the battery 5 Date recue/Date Received 2020-08-28 pack 135 and the battery tray 535 can be shaped to interface with the tool 100 in an exchangeable manner. The present invention allows the versatility of using conventional batteries such as, AA, AAA, C, D and/or 9-volt sized batteries, within a battery tray while also allowing the tray to power the tool 100. For example, the battery tray 535 can receive the same type of battery (e.g., AA), or a mixture of different sized batteries (e.g., AA and AAA), and by coupling to a power circuit on the battery tray 535, can provide the necessary output to power the tool 100. The present invention also allows the tool 100 to be provided with a unitary battery such as those often seen with conventional power tools. As used herein, the term "coupled" and its functional equivalents are not intended to necessarily be limited to direct, mechanical coupling of two or more components. Instead, the term "coupled" and its functional equivalents are intended to mean any direct or indirect mechanical, electrical, or chemical connection between two or more objects, features, work pieces, and/or environmental matter. "Coupled" is also intended to mean, in some examples, one object being integral with another object. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of the inventors' contribution. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art. 6 Date recue/Date Received 2020-08-28
