Description

Modular Multitool System with Interchangeable Components Field of the Invention

[0001] The present disclosure relates generally to portable hand tools. More particularly, the disclosure relates to a modular multitool system comprising a core and a plurality of interchangeable components connectable via a common mechanical interface standard, enabling selective reconfiguration to provide different tool functions.Background of the Invention

[0002] Portable hand tools are widely used in a variety of technical, domestic, and industrial contexts to perform tasks such as manipulation, fastening, cutting, marking, and inspection. Many such tools are designed to be compact and convenient to carry, while also providing sufficient functionality for practical use. Designers of portable tools often face competing considerations relating to size, durability, usability, and the range of tasks that can be supported by a single device.

[0003] Some tools are produced with multiple functional elements integrated into a single body. While this approach can reduce the number of tools a user must carry, it can also result in compromises in ergonomics, accessibility of individual functions, or suitability for particular tasks. In other cases, tools may include removable or replaceable parts intended to extend functionality or facilitate maintenance, although such parts are often designed for limited interchangeability or are specific to a particular tool configuration.

[0004] There have also been efforts to provide tool systems comprising multiple components intended to be assembled or disassembled. However, existing approaches may involve specialised or inconsistent interfaces, may require dedicated components for different uses, or may not readily support reuse of components across different assemblies. In some instances, the structure of the tool system can limit adaptability or complicate reconfiguration by the user.

[0005] Accordingly, there remains a need in tool architectures that can support versatility and adaptability while maintaining mechanical simplicity, structuralintegrity, and ease of use. Improvements in this area may provide users with greater flexibility in how tools are assembled, used, and adapted for different tasks or environments.

[0006] The present invention seeks to provide a modular multitool system which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative.

[0007] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.Summary of the Disclosure

[0008] The present disclosure provides a modular multitool system comprising a core and a plurality of interchangeable components configured to be selectively coupled via a common mechanical interface standard. The interchangeable components include terminal modules, interface modules, functional modules, and tool tips, each being configured for direct or indirect coupling to the core or to another interchangeable component using the same interface standard.

[0009] The modular multitool system is configurable in a plurality of assembled configurations using the same set of components. In one configuration, one or more interchangeable components are coupled together to form a standalone tool assembly without the core. In another configuration, the core is incorporated and acts as a primary handle, with one or more interchangeable components assembled in series with the core along a common longitudinal axis to form a handle-based tool.

[0010] By employing a common mechanical interface standard across multiple component families, the disclosed system enables reuse of components across different configurations without modification. This architecture allows working elements, including tool tips and driver bits, to be selectively mounted to the interchangeable components to provide different tool functions, while maintaining mechanical compatibility and structural continuity.

[0011] The disclosed arrangement supports selective variation in tool length, leverage, and functional capability through reconfiguration of components, withoutrequiring dedicated components for each configuration. The modular architecture further enables integration of additional components or functions while preserving interoperability with existing components.

[0012] In some embodiments, the common mechanical interface standard may comprise one or more threaded interfaces, non-rotational keyed interfaces, or a combination thereof. Such interfaces may be configured to transmit axial loads, bending loads, and / or rotational torque between adjacent components, thereby enabling the assembled tool to withstand operational forces while remaining selectively reconfigurable.

[0013] In certain embodiments, the terminal modules may be configured as end components adapted to define terminal characteristics of an assembled tool. By way of example, a terminal module may provide a finished end surface, a stabilising surface, or an anchoring function. In some arrangements, terminal modules may include flat, domed, conical, magnetic, or illumination-providing embodiments, each sharing a common interface geometry such that different terminal characteristics may be selected without altering the remainder of the assembly.

[0014] In some embodiments, terminal modules may further include attachment features enabling temporary coupling to external items. Such features may allow a terminal module to function as a retention or attachment point while remaining interchangeable with other terminal module embodiments, thereby allowing the same component family to serve different roles depending on the assembled configuration.

[0015] Preferably, the core comprises a primary body having an exterior geometry selected to facilitate grip and torque transmission. In some embodiments, the core may define opposed flat faces, such as a hexagonal profile, which can improve rotational control during use. The core may additionally include indicia or graduations formed thereon, enabling the core to provide auxiliary functionality without requiring additional components.

[0016] In some embodiments, the core may be configured primarily for driving operations and may define an interface optimised for direct torque transfer to a working element. In other embodiments, the core may be shaped or proportioned tosupport writing or marking operations. Still further embodiments may include cores incorporating ratcheting or articulating functionality, allowing selective directional torque transmission or angular access, without requiring the surrounding components to be modified.

[0017] In certain embodiments, interface modules may be provided to enable selective spacing, alignment, or compatibility between adjacent components. Such interface modules may include spacer modules of different axial lengths, allowing the relative positions of components to be adjusted to suit a particular task. This can facilitate changes in reach, leverage, or ergonomic balance while preserving component interoperability.

[0018] In some arrangements, interface modules may comprise coupling or adaptor components configured to connect components having different interface formats or to introduce an offset or angular relationship between adjacent components. These interface modules may thereby enable access to confined spaces or compatibility with different working elements, without altering the fundamental architecture of the system.

[0019] In various embodiments, functional modules may be incorporated to provide task-specific functionality. For example, a functional module may comprise a driver module defining a socket for receiving a driver bit, thereby enabling rotational driving tasks. Other functional modules may provide illumination, level indication, measuring capability, or other active functions, with internal construction described at a high level so as not to limit implementation.

[0020] In some embodiments, functional modules may be positioned at different locations within an assembled configuration depending on the intended use. For instance, a functional module may be placed adjacent a working element for direct interaction, or spaced from a primary gripping region using one or more interface modules to improve visibility or control.

[0021] In certain embodiments, tool tips may be provided as interchangeable working elements grouped by functional category. Such categories may include cutting, scraping, opening, marking, manipulation, or specialty functions. Grouping tips in thismanner enables a wide range of tasks to be supported using a consistent mounting arrangement, without elevating any individual tip geometry to a defining feature of the system.

[0022] In some arrangements, tool tips may be mounted directly to a tool carrier, a functional module, or an interface module, depending on the configuration. This flexibility allows working elements to be repositioned within the assembly to suit different force transmission or accessibility requirements.

[0023] In various embodiments, the system may be configured to accept replaceable working elements in the form of driver bits, including commonly available bit formats. Such bits may include different profiles, lengths, or end configurations, and may be mounted directly or via adaptor components. Treating such bits as compatible working elements allows the system to leverage existing standards while preserving the modular architecture.

[0024] In some embodiments, working elements may be exchanged without disassembling the remainder of the tool, thereby enabling rapid transition between different functions while retaining a selected component arrangement. This can reduce the need for duplicate components and support efficient adaptation during use.

[0025] In one embodiment, the interface modules comprise a hex core driver which can be selectively connectable to the core or used in the stand-alone configuration. The hex core driver may be arranged to engage the core in a sliding, non-rotational manner such that rotational torque applied to the core is transmitted through the hex core driver. The hex core driver may be releasably retained relative to the core by a detent or similar retention feature, while remaining removable for reconfiguration or replacement. The hex core driver may include a proximal socket for receiving a driver bit and a distal threaded portion configured to engage a corresponding internal thread of a tool carrier or interface module.

[0026] In another aspect, the disclosure provides a method of configuring a modular multitool system by selectively coupling interchangeable components using acommon mechanical interface to produce either a standalone tool or a handle-based in-line configuration.

[0027] In one exemplary method, the configuration includes slidably engaging a non-rotational exterior profile of a hex core driver with a corresponding internal non-rotational profile of a core to enable torque transmission.

[0028] In a further method embodiment, the hex core driver is retained relative to the core by a releasable retention feature while allowing intentional separation of the hex core driver from the core. In some methods, a driver bit is mounted in a socket formed at a proximal end of the hex core driver and torque is transmitted from the core to the driver bit through the hex core driver.

[0029] In yet another method embodiment, assembly of the multitool includes threading a distal male interface of the hex core driver into a corresponding female thread of a tool carrier or interface module to configure the system for a selected tool function. Taken together, these embodiments allow the modular multitool system to implement varying component selections, arrangements, and functional capabilities, while maintaining a consistent interface architecture and enabling reuse of components across different assembled configurations.

[0030] Other aspects of the invention are also disclosed.Brief Description of the Drawings

[0045] Referring primarily to Figure 1, there is shown a modular multitool system 100 configured as a reconfigurable ecosystem of interoperable components. The modular multitool system 100 comprises a core 130 defining a primary body configured to be gripped by a user, together with a plurality of interchangeable components selectively connectable to the core 130 and / or to one another via a common mechanical interface standard.

[0046] The interchangeable components include functional modules 140, which are configured to provide primary end-user functionality such as illumination, driving, measuring or levelling (for example, an illumination module shown in Figure 1); terminal modules 110, which define end characteristics of an assembled configuration and may provide structural, ergonomic or auxiliary functions, such as keychain attachment in embodiments; interface modules 120, which serve to connect, space, adapt or align adjacent components while preserving mechanical compatibility; tool carriers 150, which are configured to retain, support or store one or more working elements; and tool tips 160, which define interchangeable working implements configured to perform specific tasks when mounted to a tool carrier or functional module, as described in further detail below.

[0047] The common mechanical interface standard enables the interchangeable components to be directly or indirectly coupled to one another in a repeatable and mechanically secure manner. In the illustrated embodiments, the interface standard may include threaded interfaces, keyed non-rotational interfaces, or combinations thereof, although other mechanically compatible engagement arrangements may also be used. Importantly, the interface standard is shared across the component families, such that a given interchangeable component is not dedicated to a single tool format or configuration.

[0048] As a result of this architecture, the modular multitool system 100 is configurable in a plurality of different assembled configurations using the same set of components. In particular, the interchangeable components are reusable acrossconfigurations that either omit the core 130 or incorporate the core 130, without requiring modification of the components themselves.

[0049] In a standalone configuration, one or more interchangeable components are coupled together using the common mechanical interface standard to form a self-contained tool without the core 130. An example of such a standalone configuration is shown in Figure 12, in which a terminal module 110 and a tool carrier 150 are coupled via an interface module 120 to form a compact, independently operable tool. In this configuration, the assembled components collectively define a usable tool body, notwithstanding the absence of the core 130. Such standalone configurations may be particularly suited to compact carry, keychain use, or fine manipulation tasks, while still utilising the same interface standard as the larger system.

[0050] In an in-line configuration, the core 130 is incorporated and acts as the primary handle of the modular multitool system 100. One or more interchangeable components are assembled in series with the core 130 along a common longitudinal axis to define a handle-based tool. An exploded example of such an in-line configuration is illustrated in Figure 11, in which an illumination functional module 140 is positioned at one end of the assembly, a terminal module 110 is positioned at an opposing end, interface modules 120 and tool carriers 150 are arranged between components as required, and the core 130 provides a central gripping body for user interaction. The inclusion of the core 130 in this configuration enables increased leverage, reach, and torque transmission relative to the standalone configuration.

[0051] Advantageously, the modular multitool system 100 does not require a distinction between components intended for standalone use and components intended for handle-based use. The same terminal modules 110, interface modules 120, functional modules 140, tool carriers 150, and tool tips 160 may be selectively arranged either with or without the core 130, depending on the desired configuration. This reuse of components across configurations simplifies the system architecture and enables a high degree of configurability while maintaining mechanical compatibility.

[0052] As will be described in the following sections, the various component families are defined primarily by their functional role within the modular multitool system 100, rather than by rigid structural constraints. This allows individual embodiments to vary in geometry, size, or detailed construction while remaining interoperable within the overall ecosystem defined by the common mechanical interface standard.

[0053] Referring to Figures 1, 9 and 10, the modular multitool system 100 comprises one or more terminal modules 110 configured to define terminal components positioned at an end of an assembled configuration. The terminal modules 110 function primarily as anchors or end components and may serve structural, functional, or ergonomic roles depending on the embodiment. In all cases, the terminal modules 110 are interchangeable components configured to couple to other components of the system 100 via the common mechanical interface standard.

[0054] The terminal modules 110 may be selectively attached to the core 130, to an interface module 120, to a functional module 140, or directly to a tool carrier 150, depending on the assembled configuration. In this manner, the terminal modules 110 may be used both in standalone configurations that omit the core 130 and in in-line configurations in which the core 130 acts as a primary handle.

[0055] In one class of embodiments, the terminal modules 110 comprise proximal terminal modules 110a configured to define a terminal end located at an upper or distal end of an assembled tool. As illustrated in Figure 1, a proximal terminal module 110a may be positioned at an end of an in-line configuration opposite a distal terminal module 110b. The proximal terminal module 110a may provide a finished end surface, an ergonomic contact surface, or a functional interface depending on the embodiment. In some embodiments, the proximal terminal module 110a may comprise a flat end as shown in Figure 10, a domed end, or an ergonomically contoured end configured to improve comfort during use. The proximal terminal module 110a may comprise an aperture for a swivel shackle for a keychain lanyard.

[0056] In further embodiments, the proximal terminal module 110a may define a functional terminal, such as a driver-type terminal (Figure 11 , shows that the proximal terminal module 110a may enclose a driver bit 170f) , an offset or extension terminal,or a hinged or articulated terminal. Such embodiments may facilitate access to confined spaces, angular engagement, or extended reach, while still conforming to the common mechanical interface standard. Where provided, any hinge, offset, or extension functionality is preferably described at a functional level, without limiting the internal mechanism by which such movement is achieved.

[0057] In another class of embodiments, the terminal modules 110 comprise distal terminal modules 110b configured to define a terminal end located at a lower or proximal end of an assembled configuration. Figure 9 illustrates several example embodiments of distal terminal modules 110b. In these embodiments, the distal terminal module 110b may be configured to provide stabilisation, surface engagement, or secondary functionality at the end of the tool opposite a working element.

[0058] For example, a distal terminal module 110b may comprise a flat base configured to rest against a surface, a conical base configured for centring or locating engagement, or a magnetic base configured to retain the tool against a ferromagnetic surface. In other embodiments, the distal terminal module 110b may incorporate an illumination function, such as a light-emitting module, enabling the terminal end to provide directional lighting when the modular multitool system 100 is oriented toward a work area.

[0059] In a further class of embodiments, the terminal modules 110 comprise keychain terminal modules 110c, as illustrated in Figure 10. The keychain terminal modules 110c are configured to facilitate attachment of a standalone configuration or subassembly to a keychain, lanyard, loop, or similar carry accessory. Such embodiments may include a through-opening, shackle, or attachment feature formed integrally with or coupled to the terminal module 110c. The keychain terminal modules 110c may be provided in short or long variants, and in male or female interface variants, while remaining mechanically compatible with the remainder of the system 100.

[0060] Advantageously, the terminal modules 110 are not limited to use at a single end of the modular multitool system 100, nor are they restricted to a single configuration. The same terminal module 110 may be repositioned, substituted, oromitted entirely depending on the desired assembly. This flexibility allows the user to tailor the end characteristics of the tool for different tasks, environments, or carry preferences without altering the remainder of the system.

[0061] It will be appreciated that the specific forms illustrated in Figures 1, 9 and 10 are exemplary only, and that additional terminal module embodiments may be provided without departing from the modular architecture described herein, provided such embodiments remain compatible with the common mechanical interface standard.

[0062] Referring primarily to Figures 1 and 11, the modular multitool system 100 comprises at least one core 130 defining a primary body configured to be gripped by a user. The core 130 functions as the principal handle in core-inclusive, in-line configurations of the modular multitool system 100 and provides a structural backbone to which other interchangeable components are assembled in series along a common longitudinal axis.

[0063] The core 130 may be configured to interface with the terminal modules 110, interface modules 120, functional modules 140, and tool carriers 150 via the common mechanical interface standard. As with the other interchangeable components, the core 130 is not permanently fixed to any particular configuration and may be selectively included or omitted depending on the desired assembly. In this manner, the core 130 enables handle-based operation while remaining fully interoperable with standalone configurations formed without the core 130.

[0064] In one embodiment, the interface modules 120 comprises a hex core driver 120f, as illustrated in Figure 1. The hex core driver 120f may define a hexagonal exterior profile at its proximal end configured to non-rotatably engage a corresponding distal internal hexagonal profile of the core 130 in a sliding engagement, and may be retained in position by a detent or similar retention feature. This arrangement facilitates efficient transmission of torque when the modular multitool system 100 is used in rotational tasks. The proximal end of the hex core driver 120f may further comprise a diminutive socket within the confines of the hexagonal exterior profile within which a custom driver bit 170b may be retained asis shown in Figure 11. A distal end of the hex core driver 120f may define a male threaded interface configured to engage a corresponding internal female thread of the tool carriers 150 and / or interface modules 120.

[0065] The core 130 may further comprise ruler graduations formed along an exterior surface thereof, enabling the core 130 to function as a measuring aid during use. In some embodiments, the core 130 may additionally comprise a pocket clip attached thereto, allowing the modular multitool system 100 to be retained in a pocket or on a belt when not in use.

[0066] The distal end of the core 130 may retain tool tips 160 such as a stylus tip 160f as shown in Figure 11. In such embodiments, the stylus tip 160f may define an elongated, ergonomically shaped body optimised for writing or marking tasks.

[0067] Additional core embodiments may include a ratcheting driver core or a hinged driver core. In these embodiments, the core 130 may incorporate a mechanism configured to permit ratcheting rotation or angular articulation between portions of the core 130 and adjacent components. Such mechanisms may allow selective directional torque transmission or angled access to a working element. Preferably, the ratcheting or hinged functionality is described at a functional level, and the internal mechanical details by which such functionality is achieved are not limiting, provided that the core 130 remains compatible with the common mechanical interface standard.

[0068] Advantageously, the provision of multiple core embodiments allows the modular multitool system 100 to be adapted for a wide range of use cases, including high-torque driving, fine manipulation, writing, or compact carry, without altering the fundamental component ecosystem. The ability to interchange cores 130 while retaining the same terminal modules 110, interface modules 120, functional modules 140, tool carriers 150, and tool tips 160 contributes to the flexibility and reusability of the system architecture.

[0069] It will be appreciated that the specific core embodiments illustrated in Figures 1 and 11 are exemplary only, and that other core geometries, lengths, or surfacefeatures may be employed without departing from the modular principles described herein.

[0070] Referring to Figures 1, 2, 3, 6 and 8, the modular multitool system 100 further comprises one or more interface modules 120 configured to enable selective stacking, spacing, alignment, and compatibility between adjacent components of the system. The interface modules 120 function primarily as connective or intermediary components and are distinguished from functional modules 140 in that they do not, in themselves, perform a primary end-user task such as cutting, driving, or illumination.

[0071] Each interface module 120 is configured to couple to other interchangeable components using the common mechanical interface standard. As a result, interface modules 120 may be positioned between any combination of terminal modules 110, cores 130, functional modules 140, tool carriers 150, or tool tips 160, depending on the desired configuration. The interface modules 120 may be used both in standalone configurations that omit the core 130 and in in-line configurations incorporating the core 130.

[0072] In one class of embodiments, the interface modules 120 comprise spacer modules configured to adjust the axial spacing between adjacent components. As illustrated in Figure 3, spacer modules may be provided in different axial lengths, such as a long spacer 120c, a medium spacer 120d, and a short spacer 120e. The spacer modules may be used, for example, to extend the reach of a working element, to reposition a functional module 140 relative to the core 130, or to provide ergonomic spacing for grip or manipulation. In some embodiments, a short spacer 120e may be dimensioned for use with stylus-type or marking-type working elements, while longer spacers may be used to increase leverage or clearance.

[0073] In another class of embodiments, the interface modules 120 comprise coupling modules configured to connect adjacent components in a non-coaxial or offset arrangement. For example, interface modules may define an offset coupling or connector configured to laterally or angularly offset one component relative to another. Such coupling modules may facilitate access to confined spaces, clearancearound obstructions, or alternative working angles, while maintaining compatibility with the remainder of the system 100.

[0074] In further embodiments, the interface modules 120 comprise adaptor modules configured to enable compatibility between different interface formats. As illustrated in Figure 11, a hex core driver 120f may function as a thread conversion adaptor or interface conversion adaptor, allowing components having different thread forms, sizes, or interface geometries to be coupled together.

[0075] Figure 6 illustrates an interface module 120f comprising a shallow hex insert or hex carrier. In such embodiments, the interface module 120f may define a non-rotational interface configured to receive or retain a working element or tool carrier 150 in a compact arrangement. This type of interface module may be particularly suited to low-profile or compact configurations where axial length is to be minimised while still providing torque transmission.

[0076] Advantageously, the interface modules 120 enable a high degree of configurability within the modular multitool system 100. By providing spacing, alignment, and compatibility functions, the interface modules 120 allow the same terminal modules 110, cores 130, functional modules 140, tool carriers 150, and tool tips 160 to be selectively arranged in different orders and orientations, supporting both compact standalone configurations and extended in-line configurations.

[0077] It will be appreciated that the interface module embodiments illustrated in Figures 2, 3, 6 and 8 are exemplary only, and that additional spacer, coupling, adaptor, or interface components may be provided without departing from the modular architecture described herein, provided such components remain compatible with the common mechanical interface standard.

[0078] Referring to Figures 1, 8 and 11, the modular multitool system 100 further comprises one or more functional modules 140 configured to perform a primary enduser function beyond connection, spacing, or compatibility. The functional modules 140 are interchangeable components that actively contribute a task-specific capability to the system, while remaining mechanically compatible with the terminal modules110, interface modules 120, cores 130, and tool carriers 150 via the common mechanical interface standard.

[0079] Each functional module 140 is configured to be selectively incorporated into either a standalone configuration formed without the core 130 or an in-line configuration incorporating the core 130. In this manner, functional capability may be provided in both compact and handle-based tool assemblies using the same functional module 140.

[0080] In one embodiment, the functional module 140 comprise an illumination module 140a configured to provide light for illuminating a work area. As illustrated in Figure 11, the illumination module 140a may include a light source, such as a lightemitting diode, together with internal electrical and mechanical components including contacts, mounting structures, and an internal power supply.

[0081] In further embodiments, the functional modules 140 comprise a level module configured to provide a visual indication of level or alignment. Such a level module may include a spirit level or vial housed within a module body, and may be provided in different sizes or formats, such as a compact level module or an elongated level module. End plugs or retaining features may be provided to secure the level element within the module body. The level module may be incorporated into an in-line configuration or used as part of a standalone configuration, depending on the arrangement of components.

[0082] Additional functional module embodiments may include a tape-measure module, a reel module, or a fire-lighting module. In these embodiments, the functional module 140 may incorporate a retractable tape, a spool or reel element, or a firestarting element respectively. As with other functional modules, such embodiments are preferably described functionally, without limiting the internal mechanisms by which the function is achieved, provided that the module remains compatible with the interface standard of the system 100.

[0083] Advantageously, the functional modules 140 enable the modular multitool system 100 to provide a wide range of active tool functions while maintaining a consistent interface architecture. The ability to selectively include, omit, or repositionfunctional modules 140 within an assembled configuration allows the user to tailor the tool to a specific task without requiring a dedicated, monolithic tool body.

[0084] Referring primarily to Figure 8, the modular multitool system 100 further comprises one or more tool tips 160 configured as interchangeable working elements mountable to other interchangeable components of the system via the common mechanical interface standard. The tool tips 160 are configured to be selectively attached to an interface module 120, preferably via screw-in interface.

[0085] Each tool tip 160 is configured to be removable and replaceable, allowing the functional output of the modular multitool system 100 to be changed without altering the surrounding components. The tool tips 160 may be used in both standalone configurations formed without the core 130 and in in-line configurations incorporating the core 130, and may be positioned at any terminal or working end of an assembled configuration.

[0086] In one group of embodiments, the tool tips 160 comprise cutting-type tips. Such cutting-type tips may include, for example, an angled blade tip 160c, a chisel-type tip 160r, or other sharpened or profiled cutting implements. These cutting-type tips are configured to perform cutting, scoring, or severing operations on materials such as packaging, cordage, plastics, thin sheet materials, or similar substrates. The cuttingtype tips may vary in edge geometry, thickness, and angle while remaining compatible with the common interface standard.

[0087] In another group of embodiments, the tool tips 160 comprise scraping-type tips. Such scraping-type tips may include, for example, an angled scraper tip 160d configured to remove residue, coatings, labels, or surface material from a workpiece. The scraping-type tips may include flat, angled, or profiled scraping surfaces depending on the intended application, while remaining mechanically compatible with the system architecture.

[0088] In a further group of embodiments, the tool tips 160 comprise opening-type tips. These may include a bottle opener tip 160g, a can opener tip 160h, or similar prying or levering implements configured to engage lids, caps, pull-tabs, or closures.Opening-type tips may be used in standalone configurations or in conjunction with the core 130 to provide additional leverage during operation.

[0089] In another group of embodiments, the tool tips 160 comprise marking-type tips. Such tips may include a screw-in punch or marker 160a, a screwless punch or marker 160b, a stylus tip 160f , or similar marking implements configured to mark, score, indent, or indicate a position on a workpiece. The stylus tip 160f may define a stem which fits into thread adapter 161. The stem may be hollow in embodiments so that it can retain the 4 mm custom bit 170b as illustrated in Figure 11.

[0090] In further embodiments, the tool tips 160 comprise manipulation-type tips. These may include fine punch-type tips, probe-type tips, or other small-form implements configured to manipulate small components, align parts, engage recesses, or perform fine mechanical tasks. Such manipulation-type tips may be particularly suited to compact configurations or applications requiring precise control.

[0091] In additional embodiments, the tool tips 160 comprise specialty-type tips. Such tips may include, for example, a T-shaped tip 160i configured to provide transverse engagement, leverage, or torque application for specialised tasks, as well as other task-specific implements. These specialty-type tips are described as optional embodiments illustrating the extensibility of the modular multitool system 100 and are not intended to be limiting.

[0092] It will be appreciated that the tool tips 160 illustrated in Figure 8 are exemplary only, and that additional tool tip embodiments may be provided without departing from the modular principles described herein, provided that such tips remain compatible with the common mechanical interface standard.

[0093] Referring to Figures 4 and 5, the modular multitool system 100 is configured to selectively accept a range of replaceable working elements in the form of driver bits 170 and related accessories. These working elements are compatible components of the system ecosystem and are not required to form part of the structural architecture of the modular multitool system 100 itself.

[0094] In the illustrated embodiments, the driver bits 170 may comprise 1 / 4-inch driver bits 170c, 170d, 170e and 4 mm precision bits 170a, 170b. The driver bits 170 areconfigured to be received by the core 130, or terminal module 110 configured for bit reception. The driver bits 170 may be single-ended or double-ended and may include a variety of working profiles, including but not limited to slotted, Phillips, Torx, hex, or proprietary profiles.

[0095] In some embodiments, the driver bits 170 may be provided in custom lengths, including shortened formats for compact configurations and extended formats for increased reach. As illustrated in Figure 4, 4 mm precision bits 170a, 170b may be formed with different axial lengths while retaining compatibility with the same receiving interface. This enables the modular multitool system 100 to be adapted for fine manipulation tasks, recessed fasteners, or clearance-limited environments without altering the surrounding components.

[0096] In further embodiments, adaptor components may be provided to enable compatibility between different bit formats. For example, an adaptor module 120 may be configured to allow a 4 mm precision bit to be used within a 1 / 4-inch driver interface, or vice versa. Such adaptor components are preferably described functionally and are not limited to a specific dimensional standard, provided that they permit mechanical engagement and torque transmission between the driver bit 170 and adjacent components of the system 100.

[0097] The driver bits 170 may be mounted in both standalone configurations formed without the core 130 as shown in Figure 12 and in in-line configurations incorporating the core 130 as shown in Figure 11. In compact standalone configurations, a driver bit 170 may be carried within a tool carrier 150 to form a small, independently operable tool. In in-line configurations, the driver bit 170 may be positioned at an end of an assembly incorporating the core 130 to provide increased leverage and torque.

[0098] It will be appreciated that the driver bit embodiments illustrated in Figures 4 and 5 are exemplary only, and that additional bit formats, lengths, or profiles may be used with the modular multitool system 100 without departing from the principles described herein.

[0099] Referring to Figures 11, 12 and 13, the modular multitool system 100 is capable of being assembled into a wide range of configurations using the same setof interchangeable components, depending on the desired function, form factor, and operating context. These figures illustrate representative examples of both core-inclusive and core-omitting configurations, and demonstrate how the modular architecture enables reuse of components across different tool formats.

[0100] Figure 11 illustrates an exploded in-line configuration of the modular multitool system 100 incorporating the core 130. In this embodiment, an functional illumination module 140a is positioned at a distal end of the assembly, the functional illumination module 140a incorporating an internal light source and associated power components, and being configured to couple to adjacent components via the common mechanical interface standard.

[0101] An interface module 120a is positioned adjacent the functional illumination module 140a. Below the interface module 120a, a tool carrier 150a retains a tool tip 160a comprising a pointed or marking-type tip, and a further tool carrier 150b retains a tool tip 160c comprising an angled wedge or blade. The 4 mm precision bit 170b is retained in a proximal socket formed in the hex core driver 120f, with one or more spacer interface modules and a screw-in tool tip (such as the stylus tip 160f) being assembled over the exposed end of the retained bit 170b, the spacer interface modules and screw-in tool tips being selectively interchangeable to vary axial length and functional output at that position. The hex core driver 120f may also retain a larger Phillips driver bit 170d at its distal end.

[0102] The core 130 is positioned centrally within the assembly and acts as a primary handle configured to be gripped by the user and may comprises ruler graduations and a pocket clip. A spade-type driver bit 170c is mounted in a proximal terminal module 110b which screws into interior thread at a proximal end of the core 130 to define an end component of the in-line configuration. The hex core driver 120f thereby acts as torque-transmitting component between the core 131 at its proximal side and the other interchangeable components at opposite side.

[0103] Figure 12 illustrates a compact standalone configuration formed without the core 130. In this embodiment, a terminal module 110, such as a keychain terminal module 110c-3, is coupled to interior thread of tool carrier 150. A driver bit 170c ismounted to the tool carrier 150 to define a working element and selectively enclosed within the interior of a distal terminal module 110c. The resulting assembly is operable as a self-contained tool notwithstanding the absence of the core 130. This configuration demonstrates that the same interchangeable components used in the in-line configuration of Figure 11 may be reused in a reduced component assembly to provide a compact tool suitable for keychain carry, pocket storage, or fine manipulation tasks.

[0104] Figure 13 illustrates a plurality of assembled configurations 100a-100j, each formed using different combinations and arrangements of the same component families. In some configurations, the core 130 is present and functions as a central handle, while in other configurations the core 130 is omitted and the assembly relies on a reduced set of components. Terminal modules 110 are positioned at one or both ends of the assemblies to define end characteristics, interface modules 120 are interposed where spacing, alignment, or compatibility is required, functional modules 140 are included to provide active tool functions, and tool carriers 150 support tool tips 160 or driver bits 170 at working ends.

[0105] These examples illustrate that the modular multitool system 100 is not limited to a single fixed arrangement or sequence of components. Rather, the order, presence, and selection of terminal modules 110, interface modules 120, functional modules 140, tool carriers 150, and working elements may be varied to suit a particular task or preference, while remaining mechanically compatible through the common mechanical interface standard.

[0106] Advantageously, the ability to transition between compact standalone configurations and extended in-line configurations using the same components allows the modular multitool system 100 to adapt to different operating conditions without requiring separate dedicated tools. The illustrated configurations further demonstrate that components are not locked to a single role or position, but may be repositioned or reused across assemblies as required.

[0107] In use, the modular multitool system 100 allows a user to selectively configure and reconfigure a tool assembly from a common set of interchangeable componentsto suit a desired task, operating environment, or form factor. The method described below is exemplary only and is intended to illustrate representative modes of use of the system 100 rather than to define a required sequence of steps.

[0108] In a first exemplary mode of use, the modular multitool system 100 is configured as a standalone configuration formed without the core 130. In this mode, the user selects one or more interchangeable components, such as a terminal module 110, an interface module 120, and a tool carrier 150, and couples them together using the common mechanical interface standard. A tool tip 160 or a driver bit 170 is mounted to the tool carrier 150 to define a working element. For example, a tool tip 160 configured for cutting, scraping, or manipulation may be mounted to a tool carrier 150, with a keychain terminal module 110c attached at an opposing end. The resulting assembly forms a compact, self-contained tool that may be operated independently of the core 130 for fine manipulation, light-duty tasks, or situations where minimal size and weight are preferred. One or more interface modules 120, such as a short spacer or adaptor module, may be interposed to adjust spacing or compatibility. This standalone configuration allows the user to perform driving tasks using commonly available 1 / 4-inch or 4 mm precision bits while maintaining a reduced overall tool length.

[0109] In a further exemplary mode of use, the modular multitool system 100 is configured as an in-line configuration incorporating the core 130. In this mode, the user positions the core 130 centrally within the assembly to act as a primary handle. One or more interchangeable components are then assembled in series with the core 130 along a common longitudinal axis. For example, a functional module 140, such as a driver module or illumination module, may be coupled to the core 130 via an interface module 120, a tool carrier 150 with a tool tip 160 or driver bit 170 and the hex core driver 120f . A terminal module 110 may be positioned at an opposing end of the core 130 to define a base, anchor, or ergonomic end surface enclosing a driver bit 170.

[0110] In this in-line configuration, the inclusion of the core 130 enables the user to apply increased leverage and torque relative to the standalone configuration. Forinstance, when performing a driving task, the user may grip the core 130 and transmit rotational force through the assembled components to the driver bit 170. When performing cutting or scraping tasks, the core 130 provides a stable gripping surface that improves control and reduces user fatigue.

[0111] The modular multitool system 100 further allows the user to transition between different tool functions by replacing only the working element while retaining the remainder of the assembly. For example, a tool tip 160 configured for cutting may be removed and replaced with a tool tip 160 configured for marking or manipulation, or a driver bit 170 may be exchanged for another bit having a different profile or length. Such replacement may be performed without disassembling the core 130 or other components, depending on the configuration.

[0112] Advantageously, the same interchangeable components may be reused across both standalone and in-line configurations during a single use session. For example, a tool tip 160 and tool carrier 150 may be removed from a standalone configuration and incorporated into an in-line configuration with the core 130 to perform a higher-torque or longer-reach task. Conversely, components may be removed from an inline configuration and reassembled into a compact standalone tool for storage or carry.

[0113] The foregoing exemplary methods of use demonstrate that the modular multitool system 100 enables a user to dynamically adapt the form and function of the tool by selective assembly and reassembly of interchangeable components using a common mechanical interface standard. The described methods are illustrative only, and additional modes of use, configurations, and sequences of assembly will be apparent to a person skilled in the art in view of the foregoing description.

[0114] The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the invention. However, it will be apparent to one skilled in the art that specific details are not required in order to practise the invention. Thus, the foregoing descriptions of specific embodiments of the invention are presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed asobviously many modifications and variations are possible in view of the above teachings.
