The present application relates generally to the field of multi-function tools. Multi-function tools typically include a pair of handles and an implement such as a wrench, pair of scissors, or pliers, along with a number of ancillary tools used to perform any number of tasks. The ancillary tools are typically pivotally attached to one end of one handle of the multi-function tool. Multi-function tools generally utilize a number of configurations intended to provide a stowed position and a deployed position for the implement and ancillary tools. One such configuration involves attaching each of the handles in a pivotal manner to the implement such that the handles may rotate about the implement to either house the implement between the handles or to position the implement in a ready-to-use orientation. Another such configuration involves slidably attaching the implement to a pair of handles such that the implement may slide between stowed and deployed configurations.
Current multi-function tools having slidably attached implements can have an audible and tactile rattle when shaken regardless of whether the implement is stowed or deployed. The implement may rattle due to small gaps between the handle slots and the sliding implement. Typically, such gaps are required due to normal manufacturing tolerances that require the slots to be larger than the sliding implement.
Current multi-function tools further are difficult to deploy in a smooth, low friction manner due to the implement necessarily having a closed position when initially deployed. Current multi-function tool designs typically hold the implement closed throughout the entire transition from the stowed position to the deployed position by having tight up-down tolerances between the implement and the handles at all times.
Current multi-function tools may further have a driver that typically swings out 180 degrees from a stowed position from a handle to an off-center deployed position relative to both handles. Such an off-center driver can make driving screws awkward and requires a user to continually adjust their grip as they make rotations of the handle.
Current multi-function tools may further have handle profiles that are either U-channel shaped or W-channel shaped when viewed as a cross-section. U-channel shaped handles typically have the advantage of storing components in a compact manner, but require a difficult two-handed action for deployment. W-channel shaped handles typically provide easier one-hand deployment of components, but are less compact in storing the components.
One embodiment relates to a multifunction tool that includes a first handle, a second handle, and a jaw assembly. Each of the first and second handles include a non-linear track forming a slot. The jaw assembly is slidably coupled to the non-linear tracks of the first and second handles. The jaw assembly is further configured to slide within the slots of the first and second handles between a stowed position within the handles and a deployed position extending from the handles.
Another embodiment relates to a multi-function tool that includes a first handle, a second handle, and a jaw assembly. Each of the first and second handles include an inner surface and an outer surface. The jaw assembly includes a pair of jaws pivotally coupled together, and each of the jaws include a tang having a wedge configured to interface with the inner surface of either the first or second handle to create an interference that pushes the jaws closed tight when the jaw assembly is slid from a stowed position to a deployed position.
Another embodiment of the invention relates to a multi-function tool that includes a first handle, a second handle, a jaw assembly, and a driver. The first handle and the second handle are pivotable between an open position and a closed position. The jaw assembly is slidably coupled to the first and second handles. The jaw assembly is also configured to slide between a stowed position within the handles and a deployed position extending from the handles. The driver is pivotally coupled to the first handle. The driver is also configured to pivot between a stowed position either within or alongside the first handle and a deployed position extending from the first handle. The driver is further configured to have an on-center position when in the deployed position relative to a combined mass of the first and second handles when the handles are in the closed position.
Another embodiment of the invention relates to a multi-function tool that includes a plurality of tools, a first handle, and a second handle. The plurality of tools each have a stowed position and a deployed position. The first handle has a first channel having a first shape configured to compactly store a tool of the plurality of tools and requiring two hands to deploy the stored tool. The second handle has a second channel having a second shape configured to store a tool of the plurality of tools less compactly than the first handle but requiring only one hand to deploy the stored tool.

According to various embodiments of multi-function tool 100, designs are provided that reduce rattling, including tactile ratting. For example, various embodiments of multi-function tool 100 reduce or eliminate rattling between implement 101 and handles 102, 103. In various embodiments, multi-function tool 100 may have a loose up-down tolerance between implement 101 and handles 102, 103 through a portion of the transition from a stowed to deployed position while still having an implement 101 that is configured to have a closed position when initially deployed. In some embodiments, multi-function tool 100 provides a driver 122 that makes driving screws less awkward than the drivers of traditional multi-function tools. Various embodiments of multi-function tool 100 further provide handles having different channel shapes, thereby providing a user with the benefits of multiple handle designs.
In the embodiments depicted in the Figures, implement 101 is a jaw assembly having a first and second pivotally connected member, each member including a tang disposed rearwardly of the pivotal connection, and a working portion disposed forwardly of the pivotal connection for, for example, gripping or cutting. In some embodiments, the pivotal connection includes a spring 160 biased to open implement 101 when deployed (see
In some embodiments, the pivotal connection of implement 101 may be at least slidably disengageable and separate from the pivotal connection of handles 102, 103. Implement 101 may be suitably made of a corrosion resistant material such as stainless steel. The side surfaces and outer exterior top and bottom of implement 101 may be highly polished to facilitate sliding relative to handles 102, 103, and may be of a weight sufficient to facilitate a forward sliding movement and locking of implement 101 in an extended position in response to inertial force without creating excessive stopping inertia. In some embodiments, multi-function tool 100 may include a spring configured deploy implement 101. The spring-loaded implement 101 may be deployed based on pushing a button, moving a lever, and so on. In some embodiments, the button or lever for releasing implement 101 may include a safety mechanism to prevent unintentional deployment of implement 101.

Second handle 103 of multi-function tool 100 may include any number of ancillary tools, including blade 123, bit holder 121, and driver 122. In some embodiments, any number of ancillary tools may be stowed within or alongside second handle 103. In one embodiment, as shown in
In some embodiments, implement 101 is coupled to first handle 102 and second handle 103 by handle rivet 150. In some embodiments, implement 101 includes first tang 152 and second tang 153, both configured to slidably couple to first handle 102 and second handle 103, respectively. Implement 101 may further include detent button 118 and spring 117, which are both configured to, when engaged, facilitate sliding implement 101 along first and second handles 102, 103. For example, in one embodiment, implement 101 may be configured to lock into place in at least one of a deployed position, stowed position, or intermediate position, and may be further configured to be unlocked by engaging detent button 118.

In some embodiments, implement 101 includes surfaces configured to interface with an inner surface of either first handle 102 or second handle 103 as the implement is slid from a stowed position to a deployed configuration. For example, as shown in
In some embodiments, implement 101 is configured to have a loose up-down tolerance with handles 102, 103 through most of the transition of the implement 101 from a stowed position to a deployed position. In some embodiments, the wedges 154, 155 do not interface with surfaces of the handles 102, 103 until the implement 101 is either fully deployed or substantially fully deployed. In some embodiments, the wedges 154, 155 interface with surfaces of the handles 102, 103 starting mid stroke. In some embodiments, the interference between wedges 154, 155 and handles 102, 103 increases as implement 101 is deployed resulting in a maximum interference once implement 101 is fully deployed. In some embodiments, a maximum interference is reached before implement 101 is fully deployed. In some embodiments, tangs 152, 153 maintain contact with respective surfaces of handles 102, 103 throughout the entire stroke of implement 101 from a stowed position to a deployed position. In some embodiments, wedges 154, 155 of tangs 152, 153 maintain contact with respective surfaces of handles 102, 103 through the entire stroke of implement 101.
In some embodiments, multi-function tool 100 may further include a detent button 118 and spring 117 configured to be engaged by a user of multi-function tool 100 to release implement 101 from a locked position so that implement 101 may slide from a stowed to deployed position or from a deployed to a stowed position. In some embodiments, the detent button 118 may be biased into a locked position along detents provided within the frame of the first and second handles 102, 103. As such, implement 101 may be selectively locked or slid along the handles 102, 103. In some embodiments, implement 101 includes a locking member that interacts with detents such that detent button 118 must be engaged to unlock implement 101 from the frame of at least one of the first and second handles 102, 103.

In some embodiments, the shape of driver 122 is configured such that bit 126 of driver 122 has an on-center position relative to handles 102, 103 when driver 122 is pivoted one-hundred-eighty degrees from the stowed position to the deployed position. In some embodiments, driver 122 pivots less than 180 or greater than 180 degrees from the stowed position to the deployed position to have an on-center position relative to handles 102, 103. In some embodiments, bit 126 of driver 122 is configured to have an on-center position relative to the combined mass of first and second handles 102, 103. In some embodiments, bit 126 of driver 122 is configured to have an on-center position relative to the width of multi-function tool 100 or a combined width of first and second handles 102, 103 without regard to the combined mass of first and second handles 102, 103.
In some embodiments, a working axis of driver 122 has an on-center position relative to components of multi-function tool 100 when driver 122 is in the deployed position. The working axis of driver 122 may be defined by a center axis of bit 126 or a center axis extending along at least a portion of driver 122. When the working axis of driver 122 is on-center relative to components of multi-function tool 100, the working axis may overlay, align with, or intersect a point on or adjacent to a component of driver 100, a midpoint between components of driver 100, or be parallel to a surface of driver 100. The working axis of driver 122 may be on-center relative to first handle 102 and second handle 103. The working axis of driver 122 may be on-center relative to portions of first handle 102 and second handle 103, such as inner surface 162 and an outer surface 172 of first handle 102, and inner surface 163 and an outer surface 173 of second handle 103.
In some embodiments, the working axis of driver 122 has an on-center position relative to outer surfaces 172, 173. In some embodiments, the working axis of driver 122 has an on-center position relative to inner surfaces 162, 163. For example, in one embodiment, the working axis of driver 122 aligns with a midpoint between inner surface 162 and inner surface 163. In another example, the working axis of driver 122 substantially aligns with a midpoint between inner surface 162 and inner surface 163. In another example, the working axis of driver 122 is an on-center position parallel to and offset from a midpoint between inner surface 162 and inner surface 163 (e.g., offset by less than 0.01 inches, less than 0.015 inches, less than 0.025 inches). In some embodiments, the working axis of driver 122 has an on-center position relative to rivet 150. In some embodiments, the working axis of driver 122 has an on-center position relative to axle screw 116 and axle screw 128. Locating the driver 122 and or the bit 126 in one of the on-center positions described above results in a bit driver that is easier for an operator to use than conventional bit drivers found in conventional multi-function tools where the bit driver may be centered relative to a single handle rather than the entire tool. Locating the driver 122 and or the bit 126 in one of the on-center positions described above makes the bit driver easier for the operator to twist and apply torque to a fastener with the multi-function tool 100 than conventional multi-function tools, in which the bit driver centered relative to a single handle may be difficult or uncomfortable for an operator to use because the axis of the bit driver is substantially offset from the axis at which the operator twists the entire multi-function tool.

It will be appreciated that the multi-function tool 100 may have handles having the same channel shape or handles having different channel shapes. In some embodiments, the handle shapes chosen for multi-function tool 100 may depend on the use of multi-function tool 100 or a user's preference. For example, a user that wishes to quickly access ancillary tools or that needs to deploy ancillary tools using only one hand may prefer a multi-function tool 100 having W-shaped channels for both first and second handles 102, 103. A user that wishes to have a multi-function tool 100 that stores ancillary tools very compactly (i.e., for a smaller overall multi-function tool or a multi-function tool including additional tools) may prefer a multi-function tool 100 having U-shaped channels for both first and second handles 102, 103. Some users may wish to enjoy the benefits that both U-shaped and W-shaped channels offer and may accordingly prefer a multi-function tool in which first handle 102 has a U-shaped channel and second handle 103 has a W-shaped channel.
In some embodiments, primary ancillary tools that are used more often (e.g., blade 123, driver 122, etc.) may be stowed within a handle having a W-shaped channel while secondary ancillary tools (e.g., awl 113, prybar 114, file 111, etc.) may be stowed within a handle having a U-shaped channel. Such a configuration may provide a user with quick one-handed access to ancillary tools that the user is more likely to use while a greater number of ancillary tools are stowed in another handle having a more compact W-shaped channel. It will be appreciated that various configurations of handle shape and arrangement of tools within various handle shapes are possible such that the advantages of a particular channel shape may be maximized while the disadvantages of a particular channel shape are minimized based on, for example, a user's preference or purpose of the particular multi-function tool.
It is important to note that the construction and arrangement of the multi-function tool as shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described herein. While the detailed drawings, specific examples, and particular formulations given describe certain exemplary embodiments, they serve the purpose as illustration only. The invention is not limited to the specific forms shown. The configuration of multi-function tool may differ depending on chosen performance characteristics and physical characteristics of the components of the multi-function tool. For example, the implement may take a variety of configurations and perform different functions depending on the needs of the user. Furthermore, other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the exemplary embodiments without departing from the scope of the invention as expressed in the appended claims. Elements shown as integrally formed may be constructed of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the nature or number of discrete elements or positions may be altered or varied. Other substitutions, modifications, changes and omissions may also be made in the design, operating conditions and arrangement of the various exemplary embodiments without departing from the scope of the present invention.
