Description

POWER TOOL WITH PO ERED AND MANUAL OPERATING MODESCROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to and the benefit of U.S. Provisional App. No. 63 / 788,551, filed April 14 2025, and entitled “POWER TOOL WITH POWERED AND MANUAL OPERATING MODES,” the entire contents of which is herein incorporated by reference.TECHNICAL FIELD

[0002] One or more embodiments of the present disclosure relate generally to a power tool, such as a powered ratchet, that is operable in a powered mode and a manual mode that generates aural or tactile feedback when a desired torque value setting has been achieved.BACKGROUND

[0003] The process of tightening a fastener to a specified torque value often necessitates the use of two distinct tools to perform two separate operations. A powered driver or ratchet may be used to initially tighten the fastener to a snug condition, followed by the application of a manual torque wrench to achieve a final torque value setting. This two-tool approach is inherently inefficient and timeconsuming, leading to reduced productivity and increased labor costs. The inefficiency arises from the need to switch between tools and the manual intervention required to ensure precise torque application.

[0004] Some existing solutions have attempted to address this issue by integrating powered drivers and ratchets with torque value setting capabilities into a single tool. These combination tools generally incorporate digital torque sensing technology to monitor and control the torque applied during the tightening process. These integrated tools, however, are often expensive and less durable due to the complexity and fragility of their digital components. The reliance on digital torque sensing also introduces potential measurement inaccuracies and points of failure,Page 1 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Psuch as sensor malfunctions or calibration issues, which can compromise the accuracy and reliability of torque value settings.

[0005] Furthermore, the integration of digital torque sensing technology in these combination tools often results in increased tool size and weight, making them less suitable for use in confined spaces or for extended periods. The additional complexity also complicates maintenance and repair, further contributing to higher operational costs. Despite these advancements, the fundamental challenge of efficiently and accurately tightening fasteners to a specified torque value setting remains unresolved, necessitating continued exploration of alternative approaches to improve the overall process.SUMMARY

[0006] The present application discloses a powered cordless power tool (e.g., a powered ratchet) having an integrated manual torque feedback mechanism (e.g., a click-over or tilt-block mechanism) configured to provide feedback indicating that a torque level has been achieved.

[0007] The disclosed powered cordless power tool with an integrated manual torque feedback (e.g., tilt-block) mechanism offers several advantages over existing solutions.

This design allows the manual torque feedback (e.g., tilt-block) mechanism to be positioned outside of the rotating driveline, maintaining its functionality without compromising the integrity of the power tool. Additionally, in at least one example embodiment, the motor controller and handle are located behind the manual torque feedback (e.g., tilt-block) mechanism, optimizing the tool's ergonomic design and ease of use.

[0084] FIGS. 1 through 12 illustrate a plurality of example embodiments of a power tool. Although the illustrated example embodiments show implementation of a power tool comprising a ratchet wrench, embodiments are not limited thereto. This disclosure contemplates the power tool being implemented as any suitable power tool that falls within the spirit and scope of the principles of this disclosure.

[0085] In a general sense, each example embodiment of the power tool may comprise one or more operational elements. Some of the possible operational elements of the power tool are illustrated in the figures and will now be described. As will be understood, incorporation of all of the elements illustrated in the figures and / or described herein is not necessary for any given embodiment of the power tool. The power tool may include any combination of the various elements Page 12 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pillustrated herein. Moreover, the power tool may include additional operational elements beyond those illustrated in the figures.

[0086] In a first example embodiment illustrated in FIGS. 1 through 7, a power tool 100 is a torque wrench that has a wrench head 101 with an anvil 118 which is configured to receive an accessory, such as a socket. The wrench head 101 is coupled to one end of a housing 102 that also contains a motor 103 and a motor controller 104. A battery interface 109 is coupled to the housing 102 and is configured to receive a battery pack for supplying electric power to the motor 103. A manual torque adjustment mechanism 110, which allows a user to select a desired torque level, is also coupled to the housing 102. The anvil 118 is operatively coupled to, and can be driven by, the motor 103 via a transmission and a ratchet mechanism (not shown).

[0087] The housing 102 extends longitudinally from the wrench head 101 to a handle 119 for manipulation by a user during operation of the power tool 100 to drive a fastener into or out of a workpiece. In some embodiments, the wrench head 101 includes a ratchet mechanism (not shown) that allows the anvil 118 to only rotate in a user-selected direction (e.g., only clockwise or only counter-clockwise). By way of example, a suitable closed-head ratchet mechanism is disclosed in U.S. Patent No. 9,067,309, and a suitable open-head ratchet mechanism is disclosed in U.S. Patent No. 11 ,691 ,253, the disclosures of which are incorporated herein by reference. In other embodiments, the wrench head 101 may include a direct drive mechanism or an impact mechanism for driving the anvil 118.

[0088] The handle 119 includes a manual torque feedback mechanism 120 for alerting the user when a selected torque level has been achieved on the fastener when operating the power tool 100 in a manually-driven operating mode. The alert may include at least one of aural, visual, and tactile feedback. In this example embodiment, the torque feedback mechanism 120 is a tilt-block mechanism, the particulars of which are discussed in further detail below. In some other embodiments, the torque feedback mechanism 120 may be an over-center mechanism or any other suitable type of mechanism that provides an alert to the user when the selected torque level is achieved.Page 13 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627P

[0089] The power tool 100 is operable in a power-driven operating mode and a manually-driven operating mode to rotate a fastener with respect to a workpiece. In the power-driven operating mode, the anvil 118 is driven by the motor 103 by way of the transmission. According to one aspect of the present disclosure, in the power-driven operating mode, the power tool 100 is configured to tighten a fastener to an intermediate torque level that is less a selected torque level. In some embodiments, tightening to the intermediate torque level is determined by sensing that an amount of current drawn by the motor 103 has reached a threshold value, to help ensure that the anvil 118 does not apply a torque to the fastener that is greater than the selected second torque level. In some embodiments, the motor 103 and motor controller 104 are configured to only drive the fastener to an intermediate torque level that is lower than a minimum selected torque level that a user can select with the torque adjustment mechanism 110. In some other embodiments, the motor controller 104 is configured to adjust the intermediate torque level that the fastener can be driven to when the power tool 100 is in the power-driven operating mode based on the selected torque level. In other words, if the selected torque level increases, then the intermediate torque level in the power-driven operating mode increases to a level that remains below the selected torque level, and if the selected torque level decreases, then the intermediate torque level in the power-driven operating mode decreases commensurately.

[0090] After the fastener has been driven to the intermediate torque value by the power tool 100 operating in the power-driven operating mode, the user can change the operating mode to the manually-driven operating mode to further increase the torque applied to the fastener until the torque feedback mechanism 120 alerts the user that the selected torque level has been achieved. Thus, the user can quickly drive the fastener to the intermediate torqued condition using the power-driven operating mode and then precisely tighten the fastener to the selected torque level using the manually-driven operating mode.

[0091] The housing 102 has an interior cavity within which the motor 103, the manual torque adjustment mechanism 110, and the torque feedback Page 14 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pmechanism 120 are partially or fully received. A handle 119 at the end of the housing 102 includes a gripping surface that enables a user to maintain a grip on the power tool 100 while performing a particular tool function or task, such as driving the fastener when the power tool 100 is in either the power-driven operating mode or the manually-driven operating mode. In some embodiments, the torque feedback mechanism 120 may cause the handle 119 of the housing 102 to deflect, thereby indicating that the selected torque level has been reached.

[0092] The motor 103 includes a drive shaft 105 that is operable to drive rotation of the anvil 118 when the power tool 100 is operating in the power-driven operating mode to apply torque to the fastener. The motor 103 may be embodied as any type of motor operable to convert energy to rotational movement. In some embodiments, a motor 103 comprises an electric motor (alternating current or direct current) that receives power, for example, from a source such as the battery connected to the battery interface 109, an external electrical source, a cordless power electrical power source, or the like. Embodiments, however, are not limited thereto. When embodied as an electric motor, the motor 103 may comprise a brushless motor; however, embodiments are not limited thereto. This disclosure contemplates the motor 103 comprising a brushed motor or any other suitable motor that falls within the spirit and scope of the principles of this disclosure. Moreover, this disclosure contemplates the motor 103 being supplied with power from any suitable power source that falls within the spirit and scope of this disclosure. For example, the motor 103 may be air driven or may comprise a pneumatic motor that is powered by compressed air introduced from an external compressed air source.

[0093] The motor controller 104 is operable to transmit one or more drive signals to the motor 103 to control the motor 103, including, for example, the rotational speed of the motor 103 and / or the torque output of the motor 103. The motor controller 104 includes, but is not limited to, one or more processors and a non-transitory memory operatively coupled to the one or more processors. The non-transitory memory comprises a set of instructions of computer-executable program code that, when executed by the one or more processors, causes the one Page 15 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Por more processors to perform operations including transmitting one or more drive signals to the motor 103 to control at least one operational feature of the motor 103.

[0094] In the first example embodiment, the electric wiring 122 that electronically couples the motor 103 to the motor controller 104 is arranged so that it does not adversely impact the manual torque adjustment mechanism 110 or the torque feedback mechanism 120 within the elongated housing 102. In particular, the motor 103 and the associated transmission are arranged or otherwise positioned in the housing 102 at a fore / front region of the housing 102 adjacent the head 101 , and the motor controller 104 and the battery interface 109 are arranged or otherwise positioned in the housing 102 downstream, in a longitudinal direction, of the motor 103 at an aft / rear region of the housing 102 near the handle 119. The manual torque adjustment mechanism 110 and the torque feedback mechanism 120 are arranged or otherwise positioned in the housing 102 at an intermediate region between the motor controller 104 and the battery interface 109. The housing 102 may include a wireway or conduit that defines a path that guides the wiring 122, which electrically couples the motor 103 to the motor controller 104 and / or the battery interface 109, around or generally parallel to the manual torque adjustment mechanism 110 and the torque feedback mechanism 120 in order to prevent interference with operation of these mechanisms. Due to such an arrangement of components in the housing 102, the motor 103, the manual torque adjustment mechanism 110, and the torque feedback mechanism 120 can operate at least generally independently of each other.

[0095] As illustrated in FIGS. 3 through 7, the manual torque adjustment mechanism 110 is operable to allow the user to set the selected torque level at which the torque feedback mechanism 120 produces the aural, visual, and / or tactile feedback. The manual torque adjustment mechanism 110 may comprise one or more bias members that are operable to apply a bias force to the torque feedback mechanism 120. In the illustrated embodiment, the bias members comprise a compression spring 111 that is arranged in the interior cavity of the housing 102. An aft end of the compression spring 111 is coupled to a spring Page 16 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pmounting plate 123. A fore end of the compression spring 111 is coupled to a pusher 117 or an actuator member. In this embodiment, the pusher 117 has a generally T-shaped cross-section that includes a stem region 126 that terminates at a head region 127. The stem region extends at least partially into the compression spring 111. The head region defines a spring seat for supporting the adjacent end of the compression spring 111 and transferring the bias force from the compression spring 111 to the torque feedback mechanism 120 during operation of the power tool 100 in the manually-driven operating mode.

[0096] A biasing force that the pusher 117 applies to the torque feedback mechanism 120 can be adjusted by adjusting the compression of the compression spring 111 with the manual torque adjustment mechanism 110. In the example embodiment, the manual torque adjustment mechanism 110 includes a collar 112 that surrounds a portion of the housing 102 and that is operable to selectively adjust the length of the compression spring 111, and thus, the bias force that is applied by the compression spring 111 against the pusher 117. The collar 112 is rotatably coupled to the housing 102 and is configured to be selectively rotated by the user to selectively adjust the length and the bias force of the compression spring 111. Rotation of the collar 112 by the user in a first direction causes increased compression of the compression spring 111, thereby increasing the bias force applied to the torque feedback mechanism 120 and correspondingly increasing the selected torque level. Rotation of the collar 112 in an opposite second direction relieves compression of the compression spring 111, thereby decreasing the bias force applied to the torque feedback mechanism 120 and correspondingly decreasing the selected torque level. Thus, the user can choose their selected torque level by simply rotating the collar 112 about the housing 102. In the illustrated embodiment, rotation of the collar 112 does not result in translation of the collar 112 in the linear direction.

[0097] In some embodiments, adjustment of the selected torque level may be operable to transmit an electrical input signal to the motor controller 104. The motor controller 104 may use this signal to reduce or stop the speed and / or the power of the motor 103 when a first torque threshold is reached, to help prevent Page 17 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pover-torquing of the fastener prior to operating in the manually-driven operating mode of the power tool 100. In other words, adjusting the selected torque level may result in an adjustment in an intermediate maximum torque level that the motor 103 can apply to the anvil 118 when the power tool 100 is operated in the power-driven operating mode to ensure that this intermediate maximum torque level is below the selected torque level. For example, in some embodiments, the motor controller 104 may reduce or cut off current supplied to the motor 103 when a lower preload or estimated torque threshold is detected that is below the manually adjustable torque range associated with the torque feedback mechanism 120.

[0098] In the first example embodiment, the collar 112 is arranged at an aft end of the housing 102, forward of the motor controller 104 and rearward of the motor 103. The collar 112 includes an internal wall that defines a cavity. An internal ring gear 114 is coupled to the internal wall and carries one or more internal ring gears 113 that are caused to rotate via selective rotation of the collar 112. A threaded screw 115 has a fore end that is coupled to the one or more internal ring gears 113 and an aft end that receives a threaded nut 116 thereon. The threaded screw 115 is caused to rotate via rotation of the internal ring gears 113, which in turn causes the threaded nut 116 to advance in a linear direction along the threaded screw 115. The threaded nut 116 has a flange that contacts the spring mounting plate 123 such that linear movement of the threaded nut 116 induces linear movement of the spring mounting plate 123, thereby selectively adjusting the length of the compression spring 111 by compressing or decompressing the compression spring 111 and correspondingly adjusting the bias force imparted by the compression spring 111 on the pusher 117.

[0099] In the manually-driven operating mode of the power tool 100, the user sets the selected torque level by rotating the collar 112. Rotation of the collar 112 in a first direction, for example, a clockwise direction, rotates the gear assembly, thereby causing the compression spring 111 to be compressed. As the applied bias force increases, the selected torque level at which the torque feedback mechanism 120 produces aural, visual, and / or tactile feedback also Page 18 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pincreases. Rotation of the collar 112 in an opposite direction relieves compression of the compression spring 111, thereby reducing the applied bias force and lowering the selected torque level.

[0100] A torque indicator member 107 may be provided on the housing 102 and may be operable to provide visual feedback to the user that indicates the selected torque level. The housing 102 may further be provided with indicia indicating what the selected torque level is set at based on the location of the torque indicator member 107. In an example embodiment, the torque indicator member 107 is coupled to the compression spring 111 and moves in a linear direction within in a guide slot 108 of the housing 102 in response to compression or relaxation of the compression spring 111.

[0101] Components of the torque feedback mechanism 120 are at least partially received in the housing 102. The torque feedback mechanism 120 includes an arm 124, a tilt-block 121, a tilt block plate 125, and the pusher 117. The arm 124 is pivotably coupled to the housing 102, and the tilt-block 121 is positioned between the arm 124 and the pusher 117 with the bias force from the compression spring 111 urging the pusher 117 against the tilt-block 121. The tiltblock 121 is configured to rotate and engage an interior wall of the housing 102 to generate at least one of aural, visual, and tactile feedback to a user in response to the torque being applied to a fastener via the anvil 118 reaching the selected torque level, and the torque required to cause the tilt-block 121 to rotate is adjustable by adjusting the biasing force being applied by the pusher 117 against the tilt-block 117. Rotation of the tilt block 121 causes the housing 102 to deflect relative to the wrench head 101. In this context, the torque feedback mechanism 120 may be regarded as a click-style torque mechanism, and the tilt-block 121 is an example of a spring-loaded member that is configured to tilt, rotate, or pivot about a pivot axis when the desired torque value setting has been achieved.

[0102] T urning now to FIGS. 8-10, a second embodiment of the power tool 200 is illustrated, with like numerals, separated by a prefix of “2,” identifying components that are generally similar to corresponding components with the first embodiment described above. For example, the power tool 200 comprises a Page 19 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pwrench head 201 that is operatively coupled to a housing 202, a motor 203, a motor controller 204, a battery interface 209 for supplying electric power to the motor 203, a manual torque adjustment mechanism 210, and a torque feedback mechanism 220. Unless otherwise noted, elements of the second embodiment that share a common last two digits with elements of the first embodiment may generally be considered similar in structure and / or function.

[0103] The internal layout of the second embodiment differs from the first embodiment in that the torque feedback mechanism 220, which is also a tilt-block mechanism in this embodiment, is arranged or otherwise positioned in the housing 202 at a fore / front region adjacent the wrench head 201. The motor 203 and associated transmission, the motor controller 204, and the battery interface 209 are all arranged or otherwise positioned in the housing 202 at an intermediate region closer to the handle 219 than to the wrench head 201. The manual torque adjustment mechanism 210 is arranged further downstream, in a longitudinal direction, of the associated transmission, the motor 203, the motor controller 204, and the battery interface 209 at an aft / rear region of the housing 202. The drive shaft 205 extends through the compression spring 211 and through the torque feedback mechanism 220. More specifically, the drive shaft 205 extends within the coils of the compression spring 205 and between two spaced apart arms 224 of the torque feedback mechanism 220. A pair of tilt-blocks 221 are disposed between the arms 224 and the pusher 217. The two spaced apart arms 224 are coupled with the housing 202 via a pivot 206, which allows the housing 202 to deflect relative to the wrench head 201 in response to the torque load at the anvil 218 reaching the selected torque level such that the tilt-blocks 221 rotate out of their respective resting conditions. FIG. 11 depicts the torque feedback mechanism 220 in a condition where the torque load at the wrench head 201 exceeds the selected torque level. The click or break-over movement from the condition of FIG.10 to the condition of FIG. 11 generates at least one of tactile and aural feedback to indicate to the user that the selected torque level has been achieved. Although the illustrated arrangement employs a tilt-block mechanism, other click-style torque mechanisms, such as over-center mechanisms, may be used.Page 20 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627P

[0104] During operation in the power-driven operating mode, the motor 203 drives the drive shaft 205 and the associated ratcheting mechanism in the power-driven operating mode to rotate the anvil 218 of the wrench head 201. The torque feedback mechanism 220 is positioned between the motor 203 and the wrench head 201 so that, during manual operation, the torque feedback mechanism 220 is loaded when a user applies torque through the handle 219 while the wrench head 201 engages a fastener.

[0105] The manual torque adjustment mechanism 210 in the second embodiment is supported in the aft region of the housing 202 and also includes a single compression spring 211 and a pusher 217. However, because the motor 203 and the associated drive train are located between the manual torque adjustment mechanism 210 and the torque feedback mechanism 220, the second embodiment employs a linkage in the form of a forked bar mechanism 222 to transmit movement of the nut 216 that is attached to the threaded screw 215 to the spring mounting plate 223. More specifically, the forked bar mechanism 222 bypasses the motor 203 in order to transmit adjustment force to the spring mounting plate 223 and the compression spring 211. The forked bar mechanism 218 functions as a linkage that extends around or alongside the motor 203 so that rotation of the adjustment member 212 (analogous to the above-discussed collar 112) at the rear of the housing 202 is translated into linear compression of the one or more compression springs 211 located forward of the motor 203. Such engagement of the forked bar mechanism 218 with the compression spring 211 causes selective adjustment of the length and the bias force of the compression spring 211, thereby setting the selected torque level at which the torque feedback mechanism 220 produces tactile and aural feedback.

[0106] Turning now to FIG. 11, a third example embodiment of the power tool 300 is shown with like numerals, separated by a prefix of “3,” identifying similar components with the above-described embodiments. For example, the power tool 300 comprises a tool head 301 operatively coupled to a housing 302, a motor 303, a motor controller 304, a battery interface 309 for supplying electric power to the motor 303, a manual torque adjustment mechanism 310, and a torque feedback Page 21 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pmechanism 320. Unless otherwise noted, elements of the third embodiment that share a common last two digits with elements of the first embodiment may generally be considered similar in structure and / or function.

[0107] In the third example embodiment, the torque feedback mechanism 320 is arranged or otherwise positioned in the housing 302 at a fore / front region adjacent the wrench head 301, in a manner generally similar to the second embodiment. The motor 303 and associated transmission, the motor controller 304, and the battery interface 309 are arranged or otherwise positioned in the housing 302 at an intermediate region. The manual torque adjustment mechanism 310 is arranged downstream, in a longitudinal direction, of the motor 303 and associated transmission, the motor controller 304, and the battery interface 309 at an aft / rear region of the housing 302. As in the second embodiment, the motor 303 and associated drive train are located between the aft manual torque adjustment mechanism 310 and the forward torque feedback mechanism 320, and the third embodiment therefore employs a linkage that bypasses the motor 303 in order to transmit adjustment force forward.

[0108] The third embodiment differs from the second embodiment primarily in the configuration of the spring arrangement and the associated linkage used to transmit adjustment force from the aft manual torque adjustment mechanism 310 to the forward torque feedback mechanism 320. As illustrated in FIG. 11, the manual torque adjustment mechanism 310 includes a pair of compression springs 311 that are arranged in parallel on opposite sides of the centrally located drive shaft 305. In other words, the drive shaft 305 is positioned between two parallel compression springs 311. The forked linkage 331 is provided to apply load from the manual torque adjustment mechanism 310 to the compression springs 311 and ultimately to the torque feedback mechanism 320. The forked linkage 331 extends around or alongside the motor 303 and applies force to opposite sides of the spring arrangement so that force from an adjustment member 312 at the rear of the housing 302 bypasses the motor 303 and is transmitted to the compression springs 311 and, in turn, to the torque adjustment mechanism 320. Thus, whereas the second embodiment employs a single spring arrangement, the third embodiment Page 22 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pemploys parallel springs 311 on opposite sides of the central drive shaft 305. In the illustrated configuration, the click-style torque mechanism of the third embodiment may also be implemented in a split arrangement on opposite sides of the central drive path so that the mechanism remains balanced about the central drive path.

[0109] As with the second embodiment, the power tool 300 may be operated in a power-driven operating mode and a manually-driven operating mode generally as described above in connection with the first embodiment. In the power-driven operating mode, the motor 303 drives the associated drive shaft 305 and ratcheting mechanism to rotate an anvil of the wrench head 301 and thereby run down a fastener to an under-torqued operating condition, for example to an estimated lower torque or preload threshold that is below the manually adjustable torque range of the manual torque adjustment mechanism 310. In the manually-driven operating mode, the user applies torque through the handle 319 while the wrench head 301 engages the fastener. When the torque applied through the handle reaches the selected torque level established by the manual torque adjustment mechanism 310, the torque feedback mechanism 320, which may be implemented as a click-style torque mechanism and, in the illustrated embodiment, as a tilt-block mechanism including one or more tilt-block members 321, clicks over or breaks over to permit limited relative movement between the wrench head 301 and the housing 302, thereby generating at least one of tactile and aural feedback to indicate that the desired torque value setting has been achieved.

[0110] FIGS. 12A-12E illustrate examples of alternate embodiments of torque feedback mechanisms. Each of these embodiments is shown in both a resting condition and in a condition where a torque level has exceeded a selected torque level. More specifically, FIG. 12A illustrates a triggering cam mechanism, FIG. 12B illustrates an over-center mechanism, FIG. 12C illustrates a triggering cam with a flexible element mechanism, FIG. 12D illustrates a tilt-block mechanism, and FIG. 12E illustrates a slipper wrench mechanism. Any of these embodiments can be of the torque feedback mechanism can be implemented into any of the above-discussed embodiments of the power tool in order to generate at Page 23 of 35Attorney Docket No. P-US-TN-2023-0505-PR_9004-7627Pleast one of audible and tactile feedback to the user to indicate that the selected torque level has been achieved.
