DETAILED DESCRIPTION

The description of the preferred embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description. The drawing figures are not necessarily to scale and certain features may be shown exaggerated in scale or in somewhat schematic form in the interest of clarity and conciseness. In this description, relative terms such as “horizontal,” “vertical,” “up,” “down,” “top,” “bottom,” as well as derivatives thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing figure under discussion. These relative terms are for convenience of description and normally are not intended to require a particular orientation. Terms including “inwardly” versus “outwardly,” “longitudinal” versus “lateral” and the like are to be interpreted relative to one another or relative to an axis of elongation, or an axis or center of rotation, as appropriate. Terms concerning attachments, coupling and the like, such as “connected” and “interconnected,” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both moveable or rigid attachments or relationships, unless expressly described otherwise. The term “operatively coupled” is such an attachment, coupling, or connection that allows the pertinent structures to operate as intended by virtue of that relationship.

When values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. As used herein, “about X” (where X is a numerical value) preferably refers to ±10% of the recited value, inclusive. For example, the phrase “about 8” preferably refers to a value of 7.2 to 8.8, inclusive; as another example, the phrase “about 8%” preferably (but not always) refers to a value of 7.2% to 8.8%, inclusive. Where present, all ranges are inclusive and combinable. For example, when a range of “1 to 5” is recited, the recited range should be construed as including ranges “1 to 4”, “1 to 3”, “1-2”, “1-2 & 4-5”, “1-3 & 5”, “2-5”, and the like. In addition, when a list of alternatives is positively provided, such listing can be interpreted to mean that any of the alternatives may be excluded, e.g., by a negative limitation in the claims. For example, when a range of “1 to 5” is recited, the recited range may be construed as including situations whereby any of 1, 2, 3, 4, or 5 are negatively excluded; thus, a recitation of “1 to 5” may be construed as “1 and 3-5, but not 2”, or simply “wherein 2 is not included.”

Various embodiments are described herein. Similar features of the various embodiments are referenced by incrementing alphabetic characters, for example, “110”, “110a”, “110b”, “110c.” Each of these features may not be described with reference to each of the depicted embodiments, but one of skill in the art would understand that the features can be similar between the embodiments. In addition, features shown in, or described with reference to, one embodiment can also be provided in other embodiments, whether or not shown or described.

The multi-tools described herein can be used as a personal escape tool (PET) in emergency escape applications as well as in various other applications. The multi-tool enables the operator to insert fingers into a plurality of openings of a planar surface in order to control a variety of tools formed in, or attached to, the multi-tool. The multi-tools described herein provide for ergonomic, compact use in a variety of situations and include various tools configured to perform a variety of functions.

As shown in FIGS. 1A and 1B, according to a first embodiment, a multi-tool 100 is provided including a body 102 having a top face 104 opposing a bottom face 106. A perimeter face 108 connects the top 104 and bottom 106 faces. The body 102 can be a monolithic body. Alternatively, the top 104 and bottom 106 faces can be portions of separate components that are affixed to one another using a fastener, adhesive, snap-arms, or any other appropriate means. Although a generally circular body 102 is depicted in the figures, any suitable shape may be used.

As shown in FIGS. 3A and 3B, the multi-tool 100 is configured to fit in the palm of a hand “H”. Returning to FIG. 1, the body 102 includes a first opening 110 and a second opening 112 configured to receive fingers of the user's hand. The body 102 is designed to be comfortable and ergonomic when resting in the palm of the user's hand. In some embodiments, the perimeter face 108 of the body 102 includes a convex portion 114 spaced from the first 110 and second 112 openings in a first direction. The convex portion 114 is configured to receive and/or contact a portion of the user's palm. The perimeter face 108 of the body 102 also includes a concave portion 116 adjacent to the convex portion 114. The concave portion 116 is configured to receive a thumb of the hand when fingers are inserted into the openings 110, 112 (as shown in FIG. 3A). In some embodiments, the at least two openings 110, 112 are further configured to receive fingers of a gloved hand. In at least one embodiment, the convex portion 114 can be used as a hammer. In such embodiments, the convex portion 114 can include knurls to increase the effectiveness of the hammer. FIG. 3B shows another position in which the multi-tool 100 can be held in which the user's thumb wraps around the convex portion 114.

In one embodiment, the perimeter face 108 also includes a second concave portion 117. The second concave portion 117 is spaced from the first 110 and second 112 openings in a second direction that is transverse to the first direction. The second concave portion 117 is configured to receive additional fingers of the user, such as the ring finger, as shown in FIGS. 3A and 3B. The arrangement of the convex portion 114, the concave portion 116, and the second concave portion 117 provides an ergonomic shape and allows a user to comfortably operate the various implements of the multi-tool 100. The multi-tool 100 can be held comfortably in various positions and orientations, with either side facing the inside of the user's hand.

In various embodiments, the multi-tool 100 is approximately three inches in diameter or between peripheral edges. In another embodiment, the multi-tool 100 is between about two inches and about four inches in diameter or between peripheral edges. In other embodiments, the multi-tool 100 may be of various sizes to accommodate a variety of hand sizes as would be understood by one of ordinary skill in the art.

The body 102 can be constructed of any appropriate material. For example, the body 102 can be constructed from aluminum, steel, stainless steel, titanium, polymer, or any other appropriate material.

According to various embodiments of the present disclosure and as depicted in the figures, the multi-tool 100 is configured to allow an operator to manipulate, while applying force, various tools formed in, or attached to, the body 102. In one embodiment, the tools include features that are essential to vehicular escape.

For example, the multi-tool 100 can include a recessed blade 122 at the perimeter face 108 of the body 102. The blade 122 is configured for cutting the strap of a seatbelt, strap, or other member. In various embodiments, the recessed blade 122 may also be configured to cut string. In other embodiments, the recessed blade 122 may also be configured to act as a box cutter. In one embodiment, the blade 122 is integrally formed with the body 102. In other embodiments, the blade 122 is a separate component that is affixed to the body 102 using fasteners, adhesive, or other means, such as sandwiching the blade between the top face 104 and the bottom face 106. In one embodiment, the body 102 forms a shroud 124 that shields the blade 122 to prevent inadvertent contact and injury.

In some embodiments, body 102 includes a plurality of teeth 126 along the perimeter face 108 and configured to act as a saw blade. The teeth 126 can be integrally formed with the body 102 or, alternatively, can be a portion of an insert or accessory that is affixed or attached to the body 102. When a user grasps the multi-tool 100 with their fingers inserted into the first opening 110 and the second opening 112, force may be applied to saw or cut objects using the plurality of teeth 126.

One or more of the teeth 126 can be used as a glass breaker. By grasping the body 102 as shown, for example, in FIGS. 3A or 3B the user can impact glass with the teeth 126. As shown in FIG. 1C, one or more of the teeth 126 can be formed from a driving bit 190. This provides storage for the driving bit 190 while at the same time providing a hardened point to allow for a large amount of force to be applied to the glass. The opposite end of the driving bit (shown disposed within the body 102) can be in the form of any appropriate driving bit, such as, for example, a Phillips driver, a slotted driver, a Torx driver, a hex driver, or any other appropriate shape. In at least one embodiment, the driving bit 190 can be inserted into the body 102 in either orientation, such that in one orientation the driving end of the bit extends from the body and can be used to tighten or loosen a screw.

In some embodiments, the body 102 includes a pry bar 128. The pry bar 128 can include a thin edge that allows the pry bar 128 to be inserted beneath an object. By applying force to the body 102, the user can apply a prying force to the object to move or dislodge the object.

The body 102 can also include a screw driver 130 extending from the perimeter face 108. The pry bar 128 and the screw driver 130 can extend from the perimeter face 108 at an incline, such that the they converge from a greater thickness to a lesser thickness at their operative end. The pry bar 128 and the screw driver 130 can be adjacent to one another and spaced to form a recess 132 configured to engage the head of a nail for nail removal. The nail can be positioned in the recess 132 and a force applied to the body 102 to remove or loosen the nail.

In addition, one or more tools can be positioned interior to the perimeter face 108 of the body 102. For example, a wrench opening 134 configured to impart torsion force on hexagonal head screws extends between the top 104 and bottom 106 faces and extends to the perimeter face 108. In another embodiment, the wrench opening 134 is closed at the perimeter face 108. The wrench opening 134 is formed by an upper jaw 136 and a lower jaw 138. The upper jaw 136 and the lower jaw 138 diverge at an angle such that the distance between the upper jaw 136 and the lower jaw 138 is larger at the perimeter face 108 than near the center of the body 102. In one embodiment, the upper jaw 136 is substantially smooth and the lower jaw 138 includes a plurality of valleys. Each of the plurality of valleys is configured to engage a different size hex head screw. In another embodiment, the upper jaw 136 includes a plurality of valleys and the lower jaw 138 is substantially smooth. In another embodiment, both the upper jaw 136 and the lower jaw 138 include valleys. In some embodiments, the upper jaw 136 and/or lower jaw 138 are textured to grip a screw or bit disposed therein. In other embodiments, separate wrench openings are provided for various size screws, bolts, or nuts. The wrench openings 134 can be used for hex head screws, oxygen tank valves, gas-cut off valves or any other appropriate member.

The body 102 can also include a bottle opener 140 along the perimeter face 108. The bottle opener 140 is configured to engage a bottle cap for opening bottle.

As shown in FIGS. 1A and 2, the tool 10 can also include a driving bit 250 having a first driving end 252 and a second driving end 254. The first driving end 252 includes a first shoulder 252a and the second driving end 254 includes a second shoulder 254a. As shown best in FIG. 2, the driving bit 250 is configured to be received in a cavity of the body, for example the wrench opening 134, such that the first shoulder 252a contacts the top face 104 and the second shoulder 254a contacts the bottom face 106. As a result, the first driving end 252 extends away from the mid-plane ‘A’ of the body 102 in a first direction and the second driving end 254 extends away from the mid-plane in an opposite second direction.

Engagement of the driving bit 250 with the multi-tool 100 allows the driving bit 250 to be used to tighten or loosen screws. Additionally, because both the first driving end 252 and the second driving end 254 extend from the body 102, the body 102 can be turned over to quickly switch from using the first driving end 252 to the second driving end 254. For example, the first driving end 252 can be in the form of a Philips-head driver and the second driving end 254 can be in the form of a slotted-head driver. As a result, the driving bit 250 can be used to tighten and loosen multiple types of screws quickly.

In some embodiments (not shown), the multi-tool 100 includes other tools including a high torque socket (driver slot), carbineer clip, LED light, and/or a compass. The multi-tool 100 can also include various other tools as would be understood by one of ordinary skill in the art.

In another embodiment, shown in FIGS. 4A and 4B, the multi-tool 100a can include a deployable knife 178a. In the collapsed position, the blade 179a of the deployable knife 178a is disposed within the shroud 124a of the body 102a. As a result, the blade 179a can be used to cut a seat belt, strap, or other member. In the deployed position, as shown in FIG. 4B, the deployable knife 178a can be used as a traditional knife. The knife 178a is pivotable about an axis that is substantially perpendicular to the mid-plane ‘A’.

In addition, the multi-tool 100a can include a bit holder 150a. The bit holder 150a can be fixedly or removably secured to the body 102a. For example, the body 102a can include a recess into which the bit holder 150a can snap into. The bit holder 150a can be configured to retain a single ended bit (as shown in FIGS. 4A and 4B) or a double-ended bit (as shown in FIG. 1A).

In another embodiment, shown in FIGS. 5A-5C, a multi-tool 100b includes a movable lower jaw 138b. The movable lower jaw 138b is movable in a plane that is parallel to the midplane of the body 102b. The movable lower jaw 138b is configured such that the distance between the upper jaw 136b and the lower jaw 138b can be varied. The lower jaw 138b includes a valley configured to engage the head of a hex head screw. Translation of the lower jaw 138b allows the multi-tool 100b to accommodate a variety of sizes of hex head screws. While FIGS. 5A-5C illustrate the lower jaw 138b being the movable jaw, it is contemplated that either the upper jaw 136b or the lower jaw 138b may be movable. In addition, in one embodiment, both the upper jaw 136b and the lower jaw 138b are movable.

Any appropriate design can be used to allow for the translation of the lower jaw 138b. For example, in the embodiment illustrated in FIG. 5A, the lower jaw 138b is mounted to a lead screw 154b. Rotation of the lead screw 154b causes translation of the lower jaw 138b.

In addition, the body 102b can include a protrusion 118b extending from the perimeter face 108b. The protrusion 118b includes a pointed tip 120b configured to be used to break glass. In one embodiment, the protrusion 118b is assembled or joined to the body 102b using adhesive, screws, or any other appropriate means. In one embodiment, a portion of the protrusion 118b is disposed between one or more portions of the body 102b (e.g., between the top 104b and bottom 106b faces). In another embodiment, the protrusion 118b is integrally formed with the body 102b. The protrusion 118b can have any appropriate geometry. For example, the protrusion 118b can be conical, frustoconical, pyramidal, or any other appropriate shape. In various embodiments, the protrusion 118b and the plurality of teeth 126 (shown in FIG. 1) are provided on the same body and are spaced along the perimeter face such that the plurality of teeth 126 may engage an object in a saw-like motion without interference from the protrusion 118b.

The protrusion 118b can be constructed of any appropriate material. For example, the protrusion 118b can be constructed from aluminum, steel, stainless steel, titanium, polymer, or any other appropriate material.

In addition, in various embodiments, the first opening 110b and the second opening 112b are configured to receive fingers of a hand such that the multi-tool 100b may be used to provide impact force for the protrusion 118b to break a pane of glass.

The body 102b also includes a bit driver recess 146b. The bit driver recess 146b is a generally rectangular recess extending between the top face 104b and the bottom face 106b and includes an open end 148b at the perimeter face 108b. The bit driver recess 146b is configured to receive a bit therein such as a screw driving bit. The bit driver recess 146b is configured to receive the proximal end of the bit such that the distal, or operative, end of the bit extends from the perimeter face 108b. This allows the multi-tool 100b to interface with a screw having any head type, including a Phillips head, a slotted head, a Torx head, a hex head or any other appropriate type.

As shown best in FIG. 5B, the multi-tool 100b also includes a deployable whistle 155b. The whistle 155b is pivotably mounted to the body 102b such that the whistle 155b can be in a collapsed configuration, shown in FIG. 5A, or an extended configuration, shown in FIG. 5B. The whistle 155b can be used to signal for emergency assistance. In the collapsed configuration, the longitudinal axis ‘B’ of the whistle 155b is substantially parallel to the mid-plane ‘A’ (shown in FIG. 2). of the body 102b. In the extended configuration, the longitudinal axis ‘B’ of the whistle 155b is substantially perpendicular to the mid-plane of the body 102b.

As shown in FIG. 5C, the multi-tool 100b can also include a knife 156b and a saw 158b. The knife 156b and saw 158b can each be pivotably mounted to the body 102b such that they can be in a collapsed configuration, shown in FIG. 5A, or an extended configuration, shown in FIG. 5C. In the collapsed configuration, the respective blades of the knife 156b and saw 158b are housed within the body 102b to prevent inadvertent contact. The knife 156b and saw 158b are mounted such that they can be individually deployed to the extended configuration. The knife 156b and saw 158b pivot about an axis that extends substantially perpendicular to the mid-plane ‘A’ of the body 102b. The body 102b includes a finger recess 160b to allow a user to more easily engage and deploy the knife 156b or saw 158b.
