[0040] Referring to FIG. 2, the offset drive assembly 100 comprises a housing 110 configured in an upper enclosure portion 112 and a lower enclosure portion 114 adapted to enclose the a gear assembly 130 spaced apart by a plurality of support pins 119. The upper and lower enclosure portions 112, 114 are configured with a bearing recess 119 and generally formed of a shape of minimum dimensions and sufficient to enclose the gear assembly 120. The housing 110 further includes a plurality of openings formed in the upper enclosure portion 112 and, similarly, formed in the lower enclosure portion 114. For example, the upper enclosure portion 112 is configured with an opening 111 of suitable dimensions for the input care 132 and an opening 115 of suitable dimensions for the output gear 114. Similarly, the lower enclosure portion 114 configured with an opening 113 of suitable dimensions for the input care 132 and an opening 117 of suitable dimensions for the output gear 114. The housing 110 may be held in spaced apart relationship by a plurality of pins 116 that are configured to be received in pin mounts 118 formed in the housing 110 such as, for example, the plurality of support pins 116 may be received in openings formed in the upper and lower enclosure portions 112, 114, respectively, and affixed, welded or otherwise secured therein. The housing 110 may further be configured with a bearing recess 119 formed in the upper enclosure portion 112 and the lower enclosure portion 114 that is located adjacent each of the openings 111, 113, 115 and 117.

[0041] Referring to FIGS. 1-6, 7A-7B, the upper and lower enclosure portions 112, 114, respectively, are configured to provide sufficient space for the gear assembly 130 to operate via a drive 104 upon a fastener 102. The space relationship is maintained by the plurality of spacer pins 116 and these pins 116 are utilized to provide structure to the housing 110. For example, the plurality of pins 116 provide and support the upper enclosure portion 112 in a spaced apart relationship with the lower enclosure portion 114 functioning so as not to have the upper or lower enclosure portions 112, 114 impede the operation of the input gear 132, the output gear 138, or the overall operation of the gear assembly 130 and the offset drive assembly and system 100. The ring bearings 121 and 122 associated with the gear assembly 130 also maintain the spaced apart relationship and function to reduce friction of the gears in rotational operation. The bearings 121, 122 may be formed as a combined bearing and seal 127 and made from suitable material functioning to reduce friction and to prevent external contaminants from entering the sealed housing 110 when torqueing a fastener in an opening offset from a channel, fasteners in inaccessible locations, and a fastener in difficult confined areas. The housing 110 may be scalable in size and dimension and it should be appreciated is a non-limiting dimension, for example, the housing is formed compact in an opening offset from a channel or other fasteners in inaccessible locations, as shown in FIG. 3, or dimensioned larger based on the socket fastener adapter portion such as, for example, sized for the cupped-fastener aperture 150 efficiently and effectively torque a fastener along lengths of an elongated threaded rod. Similarly, the housing 110 may be scalable, as appropriate, as the spline drive system 160 utilizes the components of the offset torque drive assembly 100 and modifies the socket fastener aperture 141 with a spline drive 170 formed on the inner surface 140 of the concentric ring 139 of the output gear 138 to receive the insert socket 180 that may be scalable to include standard, e.g. SAE and metric, and non-standard fastener shapes and sizes which is a non-limiting dimension, for example, the socket fastener aperture be formed in fastener socket size of , , , , , 1 and metric socket sizes of 2 mm, 3 mm, 4 mm, 5, mm, 6 mm, 7 mm, 8 mm, 30 mm. Similarly the tool adapter portion may be scalable to include standard, e.g. SAE and metric, and non-standard drive shaft sizes that may include a ball bearing and spring type interconnection whereby such drive socket sizes are a non-limiting dimension, for example, tool adapter portion be formed in drive shaft socket size dimensions of , and .

[0042] Referring to FIG. 2, the gear assembly 130 is configured with a suitable gear ratio 131 sufficient to provide torque to rotate the fastener 102, thereby tightening and loosening the fastener 102 as desired. The gear assembly 130 comprises an input gear 132 and an output gear 138. The input gear 132 may be configured from a generally concentrically ring 133 having an inner surface 134 with a tool adapter portion 135 dimensioned in a shape to accept and join to the shaft 106 of the drive 104 so as to impart rotational force to the input gear 132 by the drive 104. The input gear 132 further may be configured with an outer surface 136 having a plurality of gear teeth 137 arranged concentrically around outer surface 136. The tool adapter portion 135 may be scalable to include standard, e.g. SAE and metric, and non-standard drive shaft sizes that may include a ball bearing and spring type interconnection whereby such drive socket sizes are a non-limiting dimension, for example, tool adapter portion be formed in drive shaft socket size dimensions of , and .

[0043] Similarly, output gear 138 may be configured from a generally concentrically ring 139 generally of a larger dimension that the input gear ring 133 based on the desired gear ratio 131. The output gear 138 is configured with an inner surface 140 dimensioned in a tool aperture 141 to join the operative surface of the fastener 102 so as to tighten and/or loosen drive 104 to impart rotational force thereto. The output gear 138 also may be configured with an outer surface 142 having a plurality of gear teeth 143 arranged concentrically around outer surface 142 of a suitable dimension to interface with the gear teeth 137 disposed on the outer surface 136 of the input gear 132 thereby operably connecting the gear teeth 137, 143 when imparting rotational force thereto.

[0044] In operation, the input gear 132, also sometimes referred to as a drive gear, is configured to convert torque applied thereto to the larger output gear 138 so as to move (e.g. tightening or loosening) the fastener 102. The drive 104 provides power and torque input through a shaft 106 inserted in a tool adapter portion 135. The input gear 132 and output gear 138 are operably connected by rotation of the input gear 132 whereby gear teeth 137 operably coupled to the gear teeth 143 cause the output gear 138 to rotate forwardly (e.g. clockwise) and apply torque to the fastener 102. The rotation of the input gear 132 will be opposite the rotation of the output gear 138, whereby a desired rotation of the fastener is achieved the input to the drive shaft 106 so that the output gear 138 rotates in the desired direction. For example, the input gear 132 and output gear 138 are operably connected by rotation of the input gear 132 whereby gear teeth 137 cause the output gear 138 to rotate rearward (e.g. counter-clockwise) to apply torque to the fastener 102 by the rotational torque provided by the drive 104 applied through the drive shaft 106 in the opposite direction, as shown in orientation illustrated in FIGS. 3 and 4. In this manner, the fastener 102 may be tightened or loosened depending on the rotational force and/or torque applied through the drive shaft 106 to the assembly 100. It is also appreciated by one skilled in the art that different gear ratios 131 will vary the force and torque ultimately applied to the fastener 102 by increasing or decreasing the gear ratio 131 between the input gear 132 and the output gear 138.

[0045] Referring to FIG. 2, a bearing 121 may be formed to be received and seated on a bearing surface 125 of the input drive gear 132. Similarly a bearing 122 may be received and seated on a bearing surface 126 of the output drive gear 138. For example, to ring bearings 121, designated as ring bearing 121a and 121b for ease of illustration, are configured to be received and seated on an upper and lower bearing surface 125 on either side of the input gear 132. When the upper enclosure portion 112 and lower enclosure portion 114 is closed upon the gear assembly 130, the ring bearing 121a is received in the bearing recess 123a in the upper enclosure portion 112 providing access to the tool adapter portion 135 through the opening 111. Similarly, the ring bearing 121b is received in the bearing recess 123b in the lower enclosure portion 114 providing access to the tool adapter portion 135 through the opening 113 on the reverse side of the offset drive assembly 100. Additionally, the ring bearing 122a is received in the bearing recess 124a providing access to the socket adapter portion 141 through the opening 115 in the upper enclosure portion 112. Similarly, the ring bearing 122b is received in the bearing recess 124b in the lower enclosure portion 114 providing access to the tool adapter portion 141 through the opening 117 in the lower enclosure portion, e.g. on the reverse side of the offset drive assembly 100. The bearings 121 and 122 provide support to the associated with the gear assembly 130 reducing friction of the input and output gears 132, 138 during rotational operation as well as maintain the spaced apart relationship of the upper and lower enclosure portions 112, 114 of the housing 110. The bearings 121, 122 may be formed as a combined bearing and seal 127 and made from suitable material functioning to reduce friction and to prevent external contaminants from entering the sealed housing 110 when torqueing a fastener in an opening offset from a channel, fasteners in inaccessible locations, and a fastener in difficult confined areas.

[0046] The plurality of pins 116 providing support between the upper enclosure portion 112 and lower enclosure portion 114 as well as housing the input gear 132 and the output gear 138. The plurality of pins 116 is received in the corresponding pin mount 118 aligned between the upper enclosure portion 112 and lower enclosure portion 114, as is shown in FIG. 2. The plurality of pins 116 may be joined in the pin mount 118 of the upper enclosure portion 112 and lower enclosure portion 114 by welding, adhesive, and other securing means. The plurality of pins 116 may be made from suitable materials such as, for example, metals, hardened steel, plastic, carbon fiber, nylon, and other suitable materials of sufficient strength and durability functioning to provide support between the two halves of the upper and lower enclosure portions 112, 114 of the housing 110 as well as to function to support the input gear 132 and the output gear 138 between the associated bearings 121, 122.

[0047] The housing 110 may be made from suitable materials such as, for example, metals, hardened steel, plastic, carbon fiber, nylon, and other suitable materials of sufficient strength and durability functioning to the gears and aligned fashion during rotation, to provide sufficient strength so that upon torqueing the input and output gears 132, 138, respectively that the housing 110 maintains structural integrity. The housing 110 may also be formed by sea computer numeric controlled (CNC) manufacturing, injection molding or other manufacturing techniques. Alternatively, according to another embodiment of the present invention, the housing 110 may be formed as one unit through manufacturing techniques that would eliminate the upper enclosure portion and lower enclosure portion combining these into an integral, sealed one-piece housing 110.

[0048] According to an embodiment of the present invention, for example, the gear assembly 130 includes the input gear 132 and output gear 138, as is shown in FIGS. 1 and 2. The input gear 132 is generally formed to torque the output gear 138 according to a desired gear ratio 131. The input gear 132 comprises a ring 133, of a generally concentric shape, having an inner surface 134 with a tool adapter portion 135 and an outer surface 136 with a plurality of gear teeth 137 formed thereon. The input gear 132 further comprises a bearing surface 125 located on the ring 133, on an upper and lower portion adapted to receive the bearing 121a and 121b, respectively, as is illustrated in FIG. 2. Similarly the output gear 138 comprises a ring 139, of a generally concentric shape, having an inner surface 140 with a socket fastener aperture 141 and an outer surface 142 with a plurality of gear teeth 143 formed thereon. The socket fastener aperture may be scalable to include standard, e.g. SAE and metric, and non-standard socket sizes and should be appreciated is a non-limiting dimension, for example, the socket fastener adapter be formed in socket dimensions of , , , , , 1 and metric socket sizes of 2 mm, 3 mm, 4 mm, 5, mm, 6 mm, 7 mm, 8 mm, 30 mm. The output gear 138 further comprises a bearing surface 126 located on the ring 139, on an upper and lower portion adapted to receive the bearing 122a and 122b thereon, respectively, as is illustrated in FIG. 2. Each of the input and output gears 132, 138, respectively, may be formed from suitable materials such as, for example, metals, hardened steel, plastic, carbon fiber, nylon, and other suitable materials of sufficient strength and durability functioning to the gears.

[0049] In an alternative embodiment of the present invention, as is illustrated in FIGS. 5, 6 and 7A-7B, the offset torque drive assembly 100 may be configured with a thru (through) hex-drive socket fastener aperture 141, a closed-end, or capped-bottom hex-drive socket fastener aperture 150, and a spline drive system 160 each providing the advantages of the present invention. It should be appreciated that the socket fastener aperture 141 may be made in any desired shape to cooperate with the fastener 102, for example, square, Philips-head, hexagon, star, and other fastener shapes without departing from the spirit and scope of the invention. For example, the thru hex-drive socket fastener aperture 141 may be utilized in applications and functions of a confined space, as shown in FIG. 3, and in applications of quickly moving a nut 101 along a threaded rod 103 as is shown in FIGS. 4A and 4B, whereby the offset torque drive assembly 100 may be formed with a socket fastener aperture 141 configured with a cupped-bottom socket or cupped-bottom fastener aperture 150, as shown in FIG. 6, that may be utilized in applications and functions of quickly moving a nut 101 along a threaded rod 103 when a positive engagement feel is desired, and other applications that will be apparent to the user.

[0050] According to an embodiment of the present invention, as is illustrated in FIG. 3, the offset torque drive assembly 100 has an application in confined spaces. Offset torque drive assembly 100 advantageously provides access to a fastener 102 secured an object 105 that is located in an opening 107 adjacent a channel 108 of the object 105. The fastener 102 may be accessed by the user placing the shaft 106 into the tool adapter portion 135, moving the offset drive assembly 100 in the channel 108 to the location of the opening 107 remaining attached to the shaft 106, rotating the shaft 106 to locate the socket fastener aperture 141 adjacent and then secured around the fastener 102, and then the user uses the drive 104 (i.e. the other end of the shaft 106 may be inserted into a chuck of the drive, ratchet, impact gun, drill, or other drive means) to turn the input gear 132 thereby driving the output gear 137 and turning fastener 102. The offset torque drive assembly 100 advantageously allows a user too quickly and easily access bolts, nuts, etc. that typically would not be able to be accessed without other removing other parts, or using inferior tools and methods perform the same task.

[0051] According to another embodiment of the present invention, the offset torque drive assembly 100 has an application in the construction industry to quickly run a nut 101 on a threaded rod 103 for hangers and the like. Conventional drives and extensions currently do not address problems in threading fasteners (e.g. nuts, spacers, brackets, platforms) on elongated threaded rods fixed in an object, which involves time-consuming assembly and ratcheting of the nut. For example, a hanger system for information technology (IT) cabling sets multiple parallel elongated threaded rods in a concrete ceiling for creating platforms or hangers for cabling, trays, ductwork and the like. The assembly of the hanger system involves joining a bracket between two adjacent parallel threaded rods at a predetermined height and threading nuts supporting the bracket to establish the predetermined height (e.g. nine feet (9)), and repeating for example at additional predetermined heights (e.g. 8, 7, etc.). Establishing the platform base by securing the bracket with nut at predetermined heights is repeated between adjacent parallel threaded rods to create a cabling channel supported from the ceiling at the established predetermined height. Conventional sockets are not configured to slide along an elongated length as the drive socket blocks passage through of the threaded rod. Additionally, wrenches slip off of the nut and two hands may be often required to maintain positive connection with the fastener while threading up the elongated rod. As a result, there is a need for an assembly and system to efficiently and effectively torque a fastener along lengths of an elongated threaded rod, which is currently performed by hand and has these assembly and time-consumption problems.

[0052] As a result, the time required to move the nut 101 on a threaded rod 103 can be reduced and improved, as is illustrated in FIGS. 4A-4B and 6, whereby a user locating the offset torque and drive assembly 100 on the threaded rod 103, inserting the shaft 106 of a drive 104 in the tool adapter portion 135 (i.e. the other end of the shaft 106 may be inserted into a chuck of the drive, ratchet, impact gun, drill, or other drive means), locating the cupped-fastener aperture 150 (socket fastener aperture 141) around the nut 101, and then energizing the drive 104 (e.g. a drill, ratchet, impact gun, drill, or other drive means), as shown in FIG. 3. In this manner, the drive 104 transfers torque power into the input gear 132 so as to turn the output gear 138 rotating the nut 101, which is supported in positive engagement by the cupped-fastener aperture 150, thereby threading or otherwise moving the nut 101 upwardly, or downwardly by the rotational force applied by the drive 104 through the drive shaft 104 to the offset torque drive assembly 100 as desired, on the threaded rod 103 quickly and efficiently. In accomplishing this purpose, the offset torque drive assembly 100 has a small, compact design that is easily transportable and used at the location of the construction to perform a multitude of tasks and different purpose in multiple fields of use advantageously making the offset torque drive assembly more versatile than conventional extensions and drive designs as well as overcoming the inherent problems thereof.

[0053] As is illustrated in FIGS. 7A-7B, the offset torque drive assembly 100 may be configured as a spline drive system 160. The spline drive system 160 utilizes the components of the offset torque drive assembly 100 and modifies the socket fastener aperture 141 with a spline drive 170 formed on the inner surface 140 of the concentric ring 139 of the output gear 138. One or more splines 171 may be formed in the inner surface 140 of the concentric ring 139 support of the output gear 138, as shown in FIG. 7A. As shown in FIG. 7B, a spline insert 180 comprises a concentric ring 181 having an inner surface 182 with a socket fastener aperture 141 and an outer surface 183 with a plurality of insert splines 184. The spline drive 170 is configured to receive slidably the spline insert 180 therein. The spline drive 170 and the splines 184 of the spline insert 180 are slidably received by the splines 171 of the spline drive 170 may further be magnetized so as to securely join when the spline insert 180 is slidably received by the drive 170. The spline insert 170 may be formed as the cupped-bottom fastener aperture 150 so that the spline drive 170 may operate and function to efficiently and effectively torque a fastener along lengths of an elongated threaded rod. Advantageously, the spline insert 180 may be formed in numerous designs and sold as a kit in order to provide the user with multiple options and may be formed in any desired shape to cooperate with the fastener 102, for example, square, Philips-head, hexagon, star, and other fastener shapes without departing from the spirit and scope of the invention. Advantageously, the offset torque drive system 100 has an output gear 138 with splines 171 to receive a spline insert 180 functioning to provide the user with the ability to connect to numerous variations of fastener heads and shapes allowing the offset torque drive 100 to accurately torque to a fastener 102 in an opening 107 offset from a channel 108, fasteners in inaccessible locations, and a fastener in difficult confined areas as well as to easily change to a cupped-socket fastener portion 150 configured to efficiently and effectively torque a nut 101 or other types of fasteners along lengths of an elongated threaded rod 103
