DETAILED DESCRIPTION

[0017] As discussed above, embodiments of the present disclosure relate to a hand tool and more particularly to a screw removal tool as used to improve the efficiency of removal of screws in a damaged condition.

[0018] Generally, the screw removal tool disclosed herein may be used to remove screws without the need for Phillips tip or slotted screw driver. It functions as an improved screw driver driven device with a head which grips around the head of a screw. It removes the screw by fitting around the head of the screw and engages the screw head with teeth so the user does not need a Phillips or a slotted tip screwdriver.

[0019] Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-4, various views of a screw removal tool 100.

[0020] FIG. 1 shows a screw removal tool 100, during an ‘in-use’ condition 50, according to an embodiment of the present disclosure. Here, the screw removal tool 100 may be beneficial for use by a user 40 to remove damaged screws 106. As illustrated, the screw removal tool 100 may include a screw removal tool 100 for removing damaged screws 106; the screw removal tool 100 may provide a screw removal assembly 102 that can include an extension shaft 112 (that may be configured to be insertable into a universal screwdriver 104) for torquing use (may be used with another tool not comprising a driver as well) and a body 114 which can be configured to couple to and remove a damaged screw 106 via engagement of a damaged screw 106 with an internally toothed extraction fitment 108 configured to engage the peripheral surface of a screw head 110 of a damaged screw 106 such that a grip-friction is impartable upon the screw head 110. The extension shaft 112 may be fixed to the body 114 in functional combination. Upon reading this specification, it should be appreciated that, under appropriate circumstances, considering such issues as user preferences, design preference, structural requirements, marketing preferences, cost, available materials, technological advances, etc., other screw removal tool arrangements such as, for example, a one-piece screwdriver of different sizes, internal screw head gripping teeth, arrangements, etc., may be sufficient.

[0021] According to one embodiment, the screw removal tool 100 may be arranged as a kit 105. In particular, the screw removal tool 100 may further include a set of instructions 107. The instructions 107 may detail functional relationships in relation to the structure of the screw removal tool 100 such that the screw removal tool 100 can be used, maintained, or the like, in a preferred manner.

[0022] FIG. 2 shows the screw removal tool 100 of FIG. 1, according to an embodiment of the present disclosure. As above, the screw removal tool 100 may include a screw removal assembly 102 including: an extension shaft 112 which may be configured to be insertable into a universal screwdriver 104 for torquing use. The body 114 can be configured to couple to and remove a damaged screw 106, via engagement of the damaged screw 106 with an internally toothed extraction fitment 108 shown in more detail in FIGS. 3 and 4 configured to engage a peripheral surface of a screw head 110 of a damaged screw 106 such that a grip-friction is impartable upon the screw head 106. The extension shaft 112 may include an ergonomic hand grip 118 that may be affixed to the body 114 in functional combination.

[0023] The extension shaft 112 may be able to move in a ratcheting motion internally of the ergonomic hand grip 118 and the extension shaft 112 may have a magnetized fitment receiver 116 as shown in FIG. 3. The extension shaft 112 may further include a hexagonal interior 128 to receive an internally toothed extraction fitment 108 and may be constructed of a hardened material. Additionally the extension shaft engagement lug 120 and the internally toothed extraction fitment 108 of this embodiment are integral and may be of equal length.

[0024] FIG. 3 is a cross-sectional view of the screw removal tool 100 of FIG. 1, according to an embodiment of the present disclosure. In the preferred embodiment the extension shaft 112 may have a magnetized fitment receiver 116 and the internally toothed extraction fitment 108 may be constructed of a hardened alloy material and wherein the extension shaft 112 may include an ergonomic hand grip 118 as shown in FIG. 2.

[0025] As shown in this embodiment the internally toothed extraction fitment 108 may have an extension shaft engagement lug 120 at its proximal end and a screw engagement opening 122 at its distal end. The extension shaft engagement lug 120 can have a hexagonal exterior 128 configuration approximately ¼ inch in diameter extending approximately half a length of the body 114 and the magnetized fitment receiver 116 should have a hexagonal interior for receiving the extension shaft engagement lug 120 having a hexagonal exterior 128. Also shown in FIG. 3 the screw engagement opening 112 may be slightly larger at the distal end than at the proximal end and the internally toothed extraction fitment 108 may have a wall thickness 132 greater at the proximal end and slightly lesser at its distal end extending approximately half a length of the body 114.

[0026] FIG. 4 is an end view of the screw removal tool 100 of FIG. 1, according to an embodiment of the present disclosure. This figure shows the internal screw head gripping teeth 124 of the screw engagement opening 122 of the screw removal tool 100 and is representative of the preferred embodiment. The screw engagement opening 122 in this embodiment may include a series of internal screw head gripping teeth 124 and it should be noted that the internally toothed extraction fitment 108 can be constructed in various sizes and the internal screw head gripping teeth 124 in FIG. 4 are in vertical alignment with opening walls 126; however, in another embodiment the internal screw head gripping teeth 124 may be constructed in a vortexual alignment with opening walls 126.

[0027] FIG. 5 is a flow diagram illustrating a method for using 500 a screw removal tool 100, according to an embodiment of the present disclosure. In particular, the method 500 for using the screw removal tool 100 may include one or more components or features of the screw removal tool 100 as described above. As illustrated, the method 500 for screw removal tool 100 may include the steps of: step one 501, providing a screw removal tool, for removal of a damaged screw; step two 502, inserting the internally toothed extraction fitment into a universal screwdriver; step three 503, placing internally toothed extraction fitment against damaged screw head; step four 504, torquing screw removal assembly to remove damaged screw; step five 505, removing damaged screw from internally toothed extraction fitment; step six 506, removing internally toothed extraction fitment from universal screwdriver; step seven 507, storing internally toothed extraction fitment.

[0028] It should be noted that step 506 is an optional step and may not be implemented in all cases. Optional steps of method of use 500 are illustrated using dotted lines in FIG. 5 so as to distinguish them from the other steps of method of use 500. It should also be noted that the steps described in the method of use can be carried out in many different orders according to user preference. The use of “step of” should not be interpreted as “step for”, in the claims herein and is not intended to invoke the provisions of 35 U.S.C. §112(f). It should also be noted that, under appropriate circumstances, considering such issues as design preference, user preferences, marketing preferences, cost, structural requirements, available materials, technological advances, etc., other methods of use for the screw removal tool are taught herein.

[0029] The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientist, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
