The present disclosure relates to an adaptative, multi-functional pliers enhancing tool.
Hand-held pliers include handles that lead to or are connected to jaws that may be used in various applications such as: securing a workpiece (as a vice), turning fasteners or pipes, or cutting various materials. Each particular application may present challenges to the user that can be difficult to overcome such as: insufficient transfer of force from the handles (where force is applied) to the jaws directly engaging a workpiece, unsuitable overall length of the pliers for the application, grip sustainability on the handles, and ergonomic issues or obstructions contributed to by the pliers' handle orientation relative to the user.
Disclosed is a pliers tool arranged to attach as a hosting pliers and may manipulate a separate, principal use pliers. The hosting pliers are provided with a first receiver that is connected to a first ply. The first receiver is configured to receive a handle of a principal use pliers.
Also disclosed is a pliers tool having a hosting pliers provided with a first retainer connected to or as part of a ply or its connective hardware. The first retainer being configured to retain a handle of a principal use pliers to a ply of the hosting pliers.
Further disclosed is a pressure loading box assembly (PLBA). The PLBA is arranged to facilitate the dynamic requirements of both a receiver and a retainer as part of the pliers tool such that this specific arrangement of moving and non-moving parts enables a receiver and an interactive pressure band to be forcefully guided toward each other such that they create a movement-compensating vice/retainer for a prominent protrusion such as a handle of a principal use pliers. PLBA having the capacity to function beneficially in other considerable applications separate from the pliers tool.
These and other advantages and features will become more apparent from the following description taken in conjunction with the drawings.
The subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other features and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
Referring now to the figures, where the invention will be described with reference to specific embodiments, without limiting same,
The principal use pliers (02) may provide a fixed ratio between the force applied by the user's hand(s) and the resulting force at the jaws of the principal use pliers (02) thereby rendering the user of the principal use pliers (02) unable to exert a minimum threshold of force to manipulate materials as desired such as when cutting or gripping stubborn fasteners. Factors contributing to the problem of insufficient force for the task may include the user having reduced physical strength, muscle fatigue, injury, spatial limitations interfering with the user's grip, or other limiting conditions.
The principal use pliers (02) may have a fixed length of a handle, which may reduce the amount of force applied to the jaws. The opposite could also be true in that the point of comfortable grip on the handles of a principal use pliers (02) may be inconveniently farther from the jaws than desirable, thereby producing a greater amount of force at the jaws than desired.
The principal use pliers (02) may have a fixed orientation of the handles to the jaws, which may reduce accessibility of the handle by a user of the principal use pliers (02) during specific work such as when working around a physical obstruction in a confined space or when working overhead.
The principal use pliers (02) may not include a feature to lock the principal use pliers (02) onto a workpiece thereby preventing its user from applying sustained force to achieve tasks such as clamping or propping up a workpiece for bonding or joining operations such as soldering or bead-making, or even suturing or other applications.
The principal use pliers (02) may have a fixed length, which at the handles may provide an insufficient lever arm for torque applications such that its user cannot sufficiently leverage the material in the jaws such as when trying to turn a fastener or bend sheet metal or other materials. Furthermore, a fixed length of the principal use pliers (02) may lead to the principal use pliers (02) being too short or too long for the spatial limitations when held in the user's hand.
The principal use pliers (02) may have a fixed ratio of movement between its handles and the corresponding movement at its jaws. This relationship may prevent the application of force at the jaws that reaches (but does not exceed) a desired threshold in certain applications such as press-fitting or cracking a walnut's shell without damaging the meat.
The principal use pliers (02) may have an uncomfortable, damaged, or non-insulated handle, which may limit its mechanical or safe usefulness.
As shown in
As shown in
Furthermore, the pliers tool (01) may provide solutions to a non-insulated handle of a principal use pliers (02) by possibly insulating the parts of the pliers tool (01) which may directly contact its user. Similarly, various exposed parts of the pliers tool (01) may be insulated to prevent conduction between such parts and their surroundings, which could cause problems such as arcing, and/or damage to electronics.
A pliers tool (01) may be used to control a principal use pliers (02), and some of its methods of use are described in conjunction with

FBLA rear bar raised protrusion (64a) large enough to retain end of FBLA rearward bar (64) within FBLA first ply bar (61) and small/smooth enough to fit and move freely along FBLA slotted tubular section (61a) of FBLA first ply bar (61) as governed by the FBLA adjustment screw (68).
As shown in
FBLA frontward bar (62) as an intermediate section of second frontward ply (24b) having at both ends fixed hinges, one at primary main hinge (22) attaching it to first ply (20), and one at secondary main hinge (25) attaching it to second rearward ply (23b).
As shown in
FBLA rearward bar (64) having a fixed hinge attaching one end to an end of FBLA second ply bar (63) and the other end engaging the end of FBLA adjustment screw (68) within FBLA slotted tubular section (61a) to create the aforementioned FBLA adjustable hinge (66) within FBLA first ply bar (61).
As shown in
FBLA second ply bar (63) and FBLA rearward bar (64) may become parallel under load if the jaws of the pliers tool (01) are being closed against an opposing force and FBLA adjustment screw (68) is positioned to permit parallel sections under load. If these two sections become parallel (making a single, segmented linear section) under load and are then forced to break parallel on the opposite side from where they started, they can become locked into position if their continued movement to the opposite side from where they started is restricted just “over-center” or beyond parallel. At this point, the force of the workpiece once working to separate the jaws of the pliers tool (01) becomes rerouted such that it keeps the jaws of the pliers tool (01) closed. FBLA over-center hinge (65) refers to being “over-center” with respect to secondary main hinge (25) and FBLA adjustment hinge (66). This beyond parallel, over-center condition will be stopped slightly over-center when curved section of FBLA rearward bar (64) presses into frontward end of FBLA release lever (69), and the force against one end of said lever will pop the other side up into the ready position. Once ready, squeezing rearward end of FBLA release lever (69) against its respective handle creates a strong leveraging force to separate the handles and disengage over-center condition and release the locking feature.
Over-center condition could also be released at one or more different release points through various methods (if necessary) or by simply separating the handles forcibly.

First receiver (40a) and first retainer (45a) integral to PLBA (50).
As shown in
PLBA band guide (53) to assist travel of PLBA band (52) may be present within PLBA (50), resting on top of first receiver attaching plate (35a), which uses attaching hardware (33) or bonds (with an adhesive) to PLBA (50). First receiver attaching plate (35a) further attaches to pivot/swivel mounting plate (P/SMP) (37) such that the mating surfaces between first receiver attaching plate (35a) and pivot/swivel mounting plate (37) allow for swiveling motion of PLBA (50) with respect to pliers tool (01) to which it is attached.
As shown in
P/SMP (37) may facilitate secure adjustments in the orientation of a principal use pliers (02) to the pliers tool (01) and its user while being hosted by the pliers tool (01) by allowing the handles of the hosted pliers to swivel at the mating or junction of P/SMP (37) and receiver attaching plate (35) laterally on a rotation axis away from the axis occupied by the handles of the pliers tool (01). Secure aspect of mating may be achieved by means such as having friction-producing knurling or offset ridges and valleys on opposing surfaces positioned in opposition to one another so as to allow for a mating of ridges and valleys in specific positions.
Pivot/swivel mounting plate (P/SMP) (37) hinged attachment to jaw arm (26) allows a handle of a hosted principal use pliers (02) to pivot forward and rearward to the pliers tool (01) on an axis/plane they may share while also allowing the principal use pliers (02) to swivel through the aforementioned rotation axis, separate from the plane capable of being shared by both handle sets.
P/SMP (37) pivoting allowance as the primary facilitators of movement as needed for the normal operation (opening and closing) of the handles of a principal use pliers (02) hosted by the pliers tool (01) by allowing the hosted pliers' handles to be held securely throughout a range of pivoting or teetering in two directions, sharing the axis parallel to its handles with each pivot of each jaw independently accommodating variations as needed.
P/SMP (37) swiveling allowance as secondary movements allowing for greater versatility and functionality of pliers tool (01).
PLBA band guide (53), if necessary, acts as a guide separate from guiding support which may be provided by receiver (40) itself. PLBA band (52) may crown the first receiver attaching plate (35a) within PLBA (50) above the gateway providing entry into the assembly as needed by a handle of the principal use pliers (02) to be hosted by the pliers tool (01).
First receiver attaching plate (35a) as an attachment point, if necessary, to a tool, other assembly or workpiece separate from the pliers tool (01).
PLBA band guide (53) and first receiver attaching plate (35a) may or may not be necessary for some applications outside of the pliers tool (01), or their presence may be integral to PLBA receiver (51).
PLBA spring (55) forces PLBA band (52) towards PLBA receiver (51) so as to retain by pinning a prominent protrusion positioned in between them. PLBA (50) allowing a prominent protrusion (could be anything) to have movement between PLBA receiver (51) and PLBA band (52) within the assembly without the assembly releasing the prominent protrusion as permitted by secure but somewhat loose construction considered in the relationship between PLBA band (52) and the parts acting to guide PLBA band (52), which is either PLBA receiver (51), PLBA band guide (53), or both. The aforementioned loose construction may be facilitator of compensatory capacity of PLBA (50).
As shown in
Other constant pressure exerting means within PLBA (50) could include materials such as permanent magnets, or self-recovering materials like certain foams, rubber, or the like.
PLBA band (52) shape designed to retain (but allow some movement of a prominent protrusion (could be anything) received and retained by PLBA (50).

Each receiver (40) is arranged to support the handles of the principal use pliers (02) and may include the use of: air pressure, pneumatics, hydraulics, an adhesive or similar material, a ball/detent arrangement, a band, a bladder or pressure based mechanism, a bracket, a buckle, a cam mechanism, a channel, a clip, a collapsing shape, a conical shape, a flexible material (such as cloth, foam, plastic, rubber, or metal tie), a groove, a hook, a hook and loop fastener, a lever, a magnet, a malleable material (possibly putty), a nut/bolt arrangement, a pawl/tooth arrangement, a pocket, a post (or other protrusion), a post in hole arrangement, a tie such as rope, a seam, a sleeve, a slot, a snap, a sock, a spring, a sticky substance, a string, a strap, a tab, a textured surface, a threaded post into a tapped hole, a tube, a retaining pin, a variable shape, a vice, or the like as made by synthetic, natural, or combined materials.
Each retainer (45) may be arranged to retain a principal use pliers' (02) handle in its respective jaw with the use of: air pressure, pneumatics, hydraulics, a 4-bar-linkage, an adhesive or similar material, a ball/detent arrangement, a band, a bladder or pressure based mechanism, a bracket, a buckle, a cam mechanism, a channel, a clip, a collapsing shape, a conical shape, a flexible material (such as cloth, foam, plastic, rubber, or metal tie), a groove, a hook, a hook and loop fastener, a lever, a magnet, a malleable material (possibly putty), a nut/bolt arrangement, a pawl/tooth arrangement, a pocket, a post (or other protrusion), a post in hole arrangement, a tie such as rope, a seam, a sleeve, a snap, a slot, a sock, a spring, a sticky substance, a string, a strap, a tab, a textured surface, a threaded post into a tapped hole, a tube, a retaining pin, a variable shape, a vice, or the like as made by synthetic, natural or combined materials.
The pliers tool (01) is arranged to attach to and manipulate a principal use pliers (02) such that the jaws of the pliers tool (01) include receivers (40) that support the handles of many types of pliers commonly used as stand-alone tools/principal use pliers (02), and tools less common (such as in special medical applications).
The hosting pliers/pliers tool (01) having a first ply (20) and a second ply (21) [made up of a rearward ply (23) and a frontward ply (24)] hingedly or otherwise movably connected to each other.
The pliers tool (01) rearward plies (23) comprising handles which may be interconnected by an FBLA rearward bar (64) with hinges [separate from the primary main hinge (22) and secondary main hinge (25)], and other parts and attaching hardware (33) as necessary to facilitate the function of an adjustable (manually) or adjusting (automatically) four bar-linkage assembly (FBLA) (60), the potential for an over-center condition, and the release of said condition.
The jaws/frontward plies (24) of the pliers tool (01) are arranged to hold the handles of other pliers. The jaw arms (26) as part of the frontward plies (24) may be considered non-direct engagement parts (but instead more primarily support or backbone sections) of the two, frontward ply (24) and may extend from a primary main hinge (22) or secondary main hinge (25) of the pliers tool (01) and may be considered parts of the jaws of the pliers tool (01). The jaw arms (26) of the pliers tool (01) may be purposefully shaped, proportioned and orientated to each other in order to allow for a wide-ranging jaw span without unnecessary bulk, thereby making them unimpeded and smoothly permissive of adequate range of motion for a principal use pliers' (02) handles while hosted by the pliers tool (01) such that the handles of the hosted principal use pliers (02) may be operated in a range acceptable for the uses associated with a principal use pliers (02).
The hosting pliers/pliers tool (01) having a first receiver (40a) attached to or as part of a first frontward ply (24a) (first jaw), the first receiver (40a) being configured to receive a handle of a principal use pliers (02).
The hosting pliers/pliers tool (01) having a second receiver (40b) connected to or as part of a second frontward ply (24b) (second jaw). The second receiver (40b) being configured to receive another handle of a principal use pliers (02).
A handle-receiving connection of the pliers tool (01) may be anywhere on the pliers tool (01) or be added to the pliers tool (01) or any other pliers as a separate device. Such parts functioning to enable the utility of the pliers tool (01) may be removable, upgradeable (permitting more than one option) or replaceable.
A first retainer (45a) of the pliers tool (01) which may be connected to or be part of a first frontward ply (24a), the first retainer (45a) being configured to retain a handle of a principal use pliers (02) to the first frontward ply (24a) of the pliers tool (01) such that the first retainer (45a) may be part of the first receiver assembly (401a). A first retainer (45a) which may be part of the disclosed PLBA (50).
A second retainer (45b) of the pliers tool (01) which may be connected to or be part of a second frontward ply (24b), the second retainer (45b) configured to retain another handle of a principal use pliers (02) to the second frontward ply (24b) of the hosting pliers such that the second retainer (45b) may be part of the second receiver (40b).
The pliers tool (01) may include providing a retainer (45) separate from the pliers tool (01) that attaches to the principal use pliers (02) or to either or both ply assemblies of the pliers tool (01) or their hinged or other movable connection(s) to keep a handle of a principal use pliers (02) in its respective receiver (40) during use. Some examples could be a clip that locks onto the end of a handle of a principal use pliers (02) thereby preventing it from falling out of its receiver (40), a long elastic band attaching to both handles of the principal use pliers (02) and then to any point on the tool such as a small hook extending from a primary main hinge (22), or a flexible or rigid wire having a magnet on an end to magnetically retain a handle of a principal use pliers (02), and on the other end having a swiveling attachment to a handle of a principal use pliers (02).
A handle-receiving connection/receiver (40) of the pliers tool (01) [part(s) that may directly contact the handle of a principal use pliers (02)] works in conjunction with (directly or indirectly) a retainer (45) or has a design such that a retainer (45) is part of the receiving connection. A retainer (45) functioning to enable the utility of the pliers tool (01) may be anywhere on the pliers tool (01) or even be added to the pliers tool (01) or any other pliers as a separate device, such as to seat a snug-fitting foam or rubber grommet, gasket, putty or the like retainer (45) onto a handle of a principal use pliers (02) prior to inserting into the pliers tool's (01) receiver (40) and then attaching another, similar functioning retainer (45) on the same handle so as to pin/sandwich the handle on both sides to the receiver (40). A receiver (40) without a fully encompassing handle support could also be used and still support a handle with the aforementioned flexible or tacky materials or the like. A single, somewhat similar functioning retainer (45) could attach to a handle on just one side of the receiver (40) or simply be placed around a handle and then “stuffed” into the receiver (40) to retain a handle of a principal use pliers (02).
The pliers tool's (01) first and second receivers (40) may be: connected to their respective frontward plies (24) by bi-directional pivot/swivel joints as enabled by pivot/swivel mounting plates (37) facilitating a range of motion that a principal use pliers' (02) handles may pass through during use; connected to their respective frontward plies (24) by bi-directional swivel/pivot joints as enabled by pivot/swivel mounting plates (37) allowing the pliers tool (01) to host a principal use pliers (02) in a plurality of orientations to the pliers tool (01) itself and the user; attached by a combination of swivel or hinge points and supportive materials having arrangements or mating surfaces within themselves or their respective plies or jaws that intentionally permit only specific, desired movements while still engaging under load such that they assist in adding to the overall rigidity and/or final locking function (if present) of the pliers tool (01) when in use. These arrangements or mating surfaces can be designed, constructed or machined to be repositionable or even removable (possibly through magnetism) and replaceable in ways so as to limit or restrict certain movements by using concepts such as pin/hole assemblies, ball/detents, or other various friction/non-friction based methods such as having knurling or offset ridges and valleys on opposing surfaces positioned in opposition to one another so as to allow for a mating of ridges and valleys in specific positions.
The pliers tool (01) may include a limiting or lockable pivot/swivel joint functioning similarly to P/SMP (37), or another limiting or lockable compensating/adjustable connection at the interface between receiver (40)/receiver assemblies (401) and jaw arms (26), for example, to temporarily secure (add rigidity to) itself or the combination of itself and a principal use pliers (02) in their desired orientation to each other thereby enhancing or expanding its capabilities before and/or after potentially being locked as by force at the handles into a position by various methods. Methods may include creating a restriction in the movement between the first or second receiver (40) and its respective jaw arm (26) or other location (point or section) of a ply assembly or its hardware by employing the restrictive forces of a magnet, other capable methods, or a combination such as: using a magnet in conjunction with a non-threaded stud (or post) in hole assembly as part of a connection, attaching hardware, or other part of the jaw such that the connection may swivel rotationally or otherwise move across an axis allowing the handles of hosted pliers to deviate laterally or otherwise from the axis occupying the handles of the pliers tool (01). This could include an offset wherein the pliers tool's (01) handles and its jaws may be parallel to one another but no longer sharing the same axis, thereby enabling true multi-axis adjustabilty to the pliers tool (01) when considering this function in conjunction with the dual-axis movement facilitated by P/SMP (50); using a magnet in conjunction with a non-threaded stud (or post) in hole assembly as a part of a receiver (40), hardware or other part of a jaw such that the connection may swivel around to a variety of secondary post in hole arrangements such that all together they allow for a choice among a variety of possible orientations between the pliers tool (01) and the principal use pliers (02) to be quickly and rigidly fixed and then unfixed/repositioned as needed [potentially while hosting a principal use pliers (02)], potentially by forcefully separating a magnetic bond, changing the orientation of the arrangement, and reconnecting the magnetic bond as an example; or the like.
As shown in
The pliers tool (01) may also utilize a sliding and locking (or other) method by which the overall length of the pliers tool (01) may be adjusted (possibly at the handles) to change its size, shape and force-applying capacities in order to accommodate different uses for various principal use pliers (02).
The combination of the pliers tool (01) and a principal use pliers (02) may enable the pliers tool (01) to: increase the force applied to the handles of a principal use pliers (02) through a force multiplying four-bar linkage assembly (FBLA) (60); increase or decrease the potential net squeezing or clamping force at the jaws of a principal use pliers (02) by changing the insertion depth of the handles of a principal use pliers (02) where they are held by the receivers (40) of the pliers tool (01) to vary a total length/lever arm; change the orientation of a principal use pliers (02) to the pliers tool (01) and its user through the bi-directional pivot/swivel joints in the jaws of the pliers tool (01) which allow for dual-axis movements of its hosted pliers' handles thereby offering more diverse capabilities to its user while working in congested or challenging environments; enable their combination to lock into a plurality of positions to manipulate or support a workpiece as facilitated by the over-center condition of a four-bar linkage assembly (FBLA) (60) which may be incorporated into the pliers tool (01); increase or decrease the potential net leveraging force at the jaws of a principal use pliers (02) by changing the insertion depths/attachment points of the handles of the principal use pliers (02) within the receivers (40) of the pliers tool (01); control an overall longer assembly or attach at a point on the handles of the principal use pliers (02) that is inaccessible to reach with a bare hand or too difficult for a bare hand to apply substantial force; deliver greater potential force while remaining more steady and more controllable at the jaws of a principal use pliers (02) by altering the ratio between the amount of movement applied by the user on the handles of the pliers tool (01) and the amount of movement transferred to the handles of the principal use pliers (02) as permitted by a four-bar linkage assembly (FBLA) (60) which may be in the pliers tool (01); allow its user the benefit of manipulating the handles of the pliers tool (01) which may be more comfortable or in better condition than those of the principal use pliers (02); provide solutions to a non-insulated handle of a principal use pliers (02) by possibly insulating the parts of the pliers tool (01) which may directly contact its user; allow its user the possible benefits of the pliers tool (01) being insulated to prevent conduction with any of its parts which could cause problems such as arcing, and/or damage to electronics; provide its user with an opportunity to focus on new or different aspects of challenging tasks otherwise unconsidered or too difficult to manage by offering its user previously non-existent, potential solutions resulting from a greater variety of options (both simple and complex) than those offered by a stand-alone, principal use pliers (02); provide combined user functionality with a simple, lightweight design with various aids for the user such as purposefully designed, bi-directionally moving receivers (40), a purposefully designed, compensating receiver (40)/retainer (45) as part of the disclosed PLBA (50), and potentially incorporating quick and simple, yet sturdy and substantial adjustments in overall jaw capacity by transposing (flipping/transposing) a receiver (40) on the pliers tool (01) or implementing a sliding and locking mechanism along a jaw arm (26) or handles of the pliers tool (01); maintain its rigidity and strength using durable materials like steel, aluminum, carbon fiber or others in the most demanding places while possibly using plastics or other materials in areas where reasonable.
