UNIVERSAL TOOL DEVICECROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of U.S. provisional patent application No. 63 / 719,339, filed on November 12, 2024, and of U.S. patent application No. 19 / 177,756 filed on April 14, 2025, and published under publication No. US 2025 / 0332749 A1 on October 30, 2025.TECHNICAL FIELD OF THE INVENTION
[0002] The present disclosure relates to tool devices, and more specifically, to a universal and adjustable tool device with a pair of handles for working out an object.BACKGROUND OF THE INVENTION
[0003] Traditional handheld tools, such as scissors, shears, trimmers, snips, pliers, or specialized tools (for use in dentistry or the like) and the like, used for working out an object, are typically made for either right-handed users or lefthanded users, but not for both. Additionally, typical hand working tools are made with a single format for a single type of use, such as conventional scissors that are made for cutting materials (plastic sheets, paper, carboard, etc.) or the ones that are angled for better cutting of tissues, liners, etc. laid on a horizontal surface.
[0004] Furthermore, some specialized tools which are made with a specific shape for a predetermined use, such as in pliers in dentistry, or the like for medical / surgical purpose, would sometimes need to be modified for use in a different use or simply to reach a different object, and in such cases different tools are therefore used (as the original ones are not adaptable).
[0005] Accordingly, there is a need for an improved universal tool device for working out an object.SUMMARY OF THE INVENTION

[0046] Referring to Figures 1 to 10, there is shown an embodiment of a universal, and typically adjustable, tool device 10 in accordance with the present invention. The tool device 10, defining a longitudinal axis 12, is used for working out an object (not shown), and comprises a pair of or first and second working (tool) members 20 (such as scissors - shown in Figs. 1-2 and 4-10, shears, trimmers, snips, pliers 120 - shown in Fig. 3, or field specialized (dentistry or medical field) and the like) pivotally connecting to one another about a main axis 22 between fully open (when positioning the device relative to the object) and closed (when working the object therebetween) configurations, and any intermediate open configuration there between. The first 20a, 120a and second 20b, 120b working members 20, 120, with respectively the first 21a and second 21b working tool section themselves, are adapted to simultaneously work the object therebetween. First 30a and second 30b handle members 30, with respectively the first 31 a and second 31b handle section themselves, pivotally connect to one another about a handle axis 32 intersecting the main axis 22 least at an intersection point P between the first and second working members 20. The first and second handle members 30 typically removably connect to the first and second working members 20, respectively, via a connecting member 40. As best seen in Figure 1 , the connecting member 40 allows a selective angular, defined as main angle M, positioning about the main axis 22 between the first and second handle members 30 and the respective first and second working members 20, for example, with the pair of working members 20’ being angularly moved upward (or counter-clockwise - also represented with the long-dash-line hexagon in Fig. 5) by main angle M of about 15°, or with the pair of working members 20”being angularly moved downward (or clockwise - also represented with the shortdash-line hexagon in Fig. 5) by main angle MBof about 30° relative to the pair of handle members 30. The connecting member 40 allows the pair of working members 20 to be typically interchangeable with another pair, while keeping the same pair of handle members 30. A retaining member 50 selectively retains the first 20a and second 20b handle members 30 and the respective first 30a and second 30b working members 20 connected to one another along the main axis 22.
[0047] As illustrated more specifically in Figures 1-3, 5, 7 and 10, the handle axis 32 is typically colinear with the main axis 22, and the first and second working members 20 are typically removably connected to one another.
[0048] Typically, the first and second working members 20 include a guide mechanism 60 allowing the first and second working members 20 to typically slidably pivot relative to one another about the main axis 22 between the open, in which the tool portion of the first and second working members 20 are spaced apart from one another (no abutment or touching) and adapted to receive or position the object therebetween, and closed, in which the tool portion of the first and second working members 20 abut to one another with no object therebetween, configurations, respectively.
[0049] Typically, the connecting member 40 includes a pin part 42 extending from each said first and second handle members 30 toward the other one said first and second handle members 30 to engage a corresponding hole part 44 extending into each said first and second working members 20. Each pin part 42 axially extends along the handle axis 32 and each hole part 44 axially extends along the main axis 22.
[0050] Each pin part 42 preferably has a generally axial elongated body (polygonal prism) with a transversal section area of a polygonal shape (preferably square, as illustrated by pin part 142 of Figure 5, or hexagonal shape 42, 42’, 42”), and each hole part 44 preferably has a corresponding generally axial elongated recess (polygonal prism) with a corresponding transversal section area of the polygonal shape to tightly removably receive the pin part 42 therein. Thepolygonal shape is typically one of a triangular (3), a square (4), an hexagonal (6), an heptagonal (7), an octagonal (8), a nonagonal (9), a decagonal (10), an hendecagonal (11), a dodecagonal (12), an hexadecagonal (16), an icosagonal (20), and a icositetragonal (24) shape, and preferably a icositetragonal shape as illustrated in the figures. As best seen in Figure 5, the hexagonal-shape pin part 42 is inserted into the corresponding icositetragonal-shape hole part 44, with the hexagonal-shape pin part 42, 42’, 42” shown either in solid lines, short-stippled lines, or long-stippled lines with the working members 20, 20’, 20” extending “inline” (horizontal), or angularly upward, or angularly downward relative to the handle members 30, respectively, in the positions shown in Figure 1.
[0051] Obviously, although not specifically illustrated herein, a person skilled in the art would readily understand that many other types of connecting member 40 or other shapes and / or combination of shapes are possible without departing from the scope of the present invention. For example, the pin part 42 could have a square shape while the hole part 44 could have a dodecagonal shape. Also, the pin part 42 could have a relatively flat plate shape (as a flat shape screwdriver), or diametrically spaced apart pins, while the hole part 44 could have a star shape with an even number of multiple corresponding star points or pin holes.
[0052] Although a person skilled in the art would readily understand that many types of different retaining members 50 are possible without departing from the scope of the present invention, as best seen in Figures 1 and 7-9, the retaining member 50 of the illustrated embodiment 10 typically includes a rod 52 extending along the handle axis 32 from the second handle member 30b toward and into a rod receiving hole 54 of the first handle member 30a. The rod 52 typically extends through respective holes 56 of the first and second working members 20 to retain the working members 20 between the handle members 30. The retaining member 50 also typically includes a lock 60 that releasably locks the handle members 30 to each other, Although the lock 60 can take many forms or shapes (such as, for example a snap fastener or the like), the illustrated lock 60 typically takes the form of a circumferential slot 62 extending radially inwardly at the free end of the rod 52 and adapted to be at least partially engageable by a locking tab 64 movably mounted on the first handle member 30a, the locking tab 64 havingan opening 66 extending therethrough and sized to selectively clear the diameter of the rod 52, and being slidably movable between a rod releasing position (when slid in the lower position - see Figure 8A) and a rod retaining position (when slid in the upper position - see Figure 8B), as schematically illustrated in Figures 8A and 8B, respectively.
[0053] In the embodiment 10, as best seen in Figures 4, 6, and 7, the illustrated guide mechanism 70 includes a typically symmetrical pin 72 and slot 74 arrangement with a slot portion 74 being arcuate about the main axis 22 that slidably receives a respective corresponding pin portion 72 there along between the fully open and closed configurations.
[0054] Preferably, the device 10 further includes a securing mechanism 80 axially securing the first 20a and second 20b working members 20 to one another along the main axis 22 while allowing the first and second working members 20 to pivot relative to one another about the main axis 22.
[0055] In the embodiment 10, again as best seen in Figures 4, 6, and 7, the illustrated securing mechanism 80 preferably includes a tab member 82 radially protruding inwardly from the respective pin portion 72 for engaging a corresponding recess member 84 radially extending inwardly from the respective slot portion 74. Typically, the securing mechanism 80 further enables the first and second working members 20 to unsecure or disconnect from one another, such as when the fully open configuration in which the tab member 82 is freed from being at least partially engaged within and retained by the recess member 84.
[0056] In another embodiment 10’ illustrated in Figures 11 to 15, the main axis 22 is angularly spaced relative to the handle axis 32, thereby defining a lateral (shift - transversal) angle L therebetween, and the intersection point P is a midpoint between the first 20a’ and second 20b’ working members 20’. As best seen in Figure 11, the connecting member 40’, and retaining member 50’, allows a selective lateral angular, defined as main angle L, positioning of the main axis 22 relative to the handle axis 32, for example, with the pair of working members 20r’ being angularly moved rearward (or counter-clockwise - seen as upward inFig. 11 - also represented with the long-dash-line hole part 44r’ in Fig. 12) by lateral angle LYof about 36°, or with the pair of working members 20f’ being angularly moved frontward (or clockwise - seen as downward in Fig. 11 - also represented with the short-dash-line hole part 44f’ in Fig. 12) by lateral angle Lzof about 18° relative to the pair of handle members 30’. This selective lateral angular positioning of the working members 20’ relative to the handle members 30’ makes the interface therebetween being at least partially hemi-spherical (three additional lateral positions, both for front and rear displacements, are schematically illustrated in Figures 12 and 13, with approximately 18° between two adjacent positions).
[0057] In this embodiment 10’, the connecting member 40’ typically allows for translational and / or rotational displacement between the first 30a’ and second 30b’ handle members 30’ and the respective first 20a’ and second 20b’ working members 20 connected thereto. Accordingly, as more specifically illustrated in Figures 12 and 14, each through-hole 56’, 56r’, 56f’ (and also each hole part 44’, 44r’, 44f’) typically tapers down in a direction extending toward the intersection point P (as best seen in Fig. 12), to allow for the lateral (“out-of-plane”) relative displacement there between, and this is why the lateral angle L typically should remain relatively small, such as 40° or less. The preferably uniform diameter of the rod (not shown) (and also the pin part 42’) is sized to fit the small diameter of the through-hole 56’, 56r’, 56f’ at the intersection point P (and also the small diameter size of the hole part 44’, 44r’, 44f’).
[0058] Because of the lateral shift of the working members 20’ relative to the handle members 30’, any move of the working members 20’ from the closed configuration to an open configuration will induce a slight variation of the position of the working members 20’ between the handle members 30’ along the handle axis 32, and this slight variation has to be accounted for, especially by the tapering of the through-hole 56’, 56r’, 56f’ and the hole part 44’, 44r’, 44f’ as well as the proper sizing thereof. Similarly, the retaining member 50, and especially the lock 60 might also need to be slightly modified or adjusted to account for the lateral angular displacements.
[0059] Although the second embodiment 10’ allows the selective lateral (front and rear) positioning of working members 20’ relative to the handle members 30’, it also allows, for each one of the selected lateral position, for the selective up and down positioning, as the first embodiment 10, but a person skilled in the art would readily understand that it could also not be the case, without departing from the scope of the present invention.
[0060] The various features described herein can be combined in a variety of ways within the context of the present disclosure so as to provide still other embodiments. As such, the embodiments are not mutually exclusive. Moreover, the embodiments discussed herein need not include all of the features and elements illustrated and / or described and thus partial combinations of features can also be contemplated. Furthermore, embodiments with less features than those described can also be contemplated. It is to be understood that the present disclosure is not limited in its application to the details of construction and parts illustrated in the accompanying drawings and described hereinabove. The disclosure is capable of other embodiments and of being practiced in various ways. It is also to be understood that the phraseology or terminology used herein is for the purpose of description and not limitation. Hence, although the present disclosure has been provided hereinabove by way of non-restrictive illustrative embodiments thereof, it can be modified, without departing from the scope and nature thereof and of the appended claims.
