Multi-purpose tool system

Abstract

A handle section has an interior tube slidably received in an exterior tube. A locking mechanism is secured to the exterior tube and includes a cylindrical finger reciprocable between an unlocking position and a locking position to allow for lengthening and shortening. A head is coupled to the interior tube. The head has a central tube formed as an extension of the interior tube. The head has a first wing with a first upper edge extending horizontally across the first wing. The first wing has a first outer edge extending vertically from the first wing parallel with and spaced from the central tube. The first wing has a first lower edge extending in a major arc between the first outer edge and the central tube.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(12) With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved multi-purpose tool system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

(13) The present invention, the multi-purpose tool system 10 is comprised of a plurality of components. Such components in their broadest context include a handle, a locking system, and a head. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

(14) First provided is a handle section 14. The handle section has an interior tube 16. The interior tube has a closed proximal end 18. The interior tube has an open distal end 20. The interior tube has a hollow chamber. The hollow chamber is provided between the closed end and the open distal end. The interior tube in a square cross sectional configuration. The interior tube has one lateral face. The lateral face has a plurality of axially spaced apertures 22.

(15) The handle section 14 also has an exterior tube 26. The exterior tube has a closed proximal end 28. The exterior tube has an open distal end 30. A hollow chamber is provided is between the closed end and the open distal end. The exterior tube has a square cross sectional configuration interiorly. The exterior tube has knurled circular cross sectional configuration exteriorly. The interior tube is slidably received in the chamber of the exterior tube.

(16) A locking mechanism 34 is provided. The locking mechanism is secured to the open distal end of the exterior tube. The locking mechanism has a cylindrical finger 36. The cylindrical finger is radially reciprocable between an unlocking position remote from the interior tube and a locking position within a preselected aperture. In this manner the handle section may be lengthened and shortened. The locking mechanism includes a rocker 38. The rocker has an upper end. The rocker has a lower end. The rocker has a pivot point 40. The pivotal point is provided between the upper end and the lower end. The upper end is operatively coupled to the cylindrical finger. More specifically as shown in FIGS. 5 and 6, the cylindrical finger 36 includes a groove 36A. The upper end of the rocker 38 continuously engages within the groove 36A and displaces the cylindrical finger 36 during reciprocating between the unlocking position and the locking position. In this manner the locking mechanism may be moved between the locking and unlocking positions. The lower end is adapted to be manipulated by a user. In this manner the cylindrical finger may be moved. The locking further includes a coil spring 42. The coil spring urges the rocker to the locking position. As shown in FIGS. 5 and 6, the locking mechanism 34 further includes a channel 34A having an upper arcuate wall portion 34B. The cylindrical finger 36 slides within the channel 34A. The cylindrical finger 36 engages with the rocker 38. The channel and the rocker 38 guide the cylindrical finger 36 reciprocating between the unlocking position and the locking position.

(17) Provided next is a head 46. The head is coupled to the open distal end of the interior tube. The head has a central tube 48. The central tube is formed as an extension of the interior tube. The central tube has a first wing 50. The central tube has a similarly configured second wing 52. The head has an upper edge 54. The upper edge extends horizontally across the first wing and the second wing. The head has a first outer edge 56. The lower edge extends vertically. The first wing is parallel with and spaced from the central tube. The head has a second outer edge 58. The second outer edge extends vertically from the second wing. The second outer edge is parallel with and spaced from the central tube. The head has a first lower edge 60. The first lower edge extends in a major arc between the first outer edge and the central tube. The head has a second lower edge 62. The second lower edge extends in a major arc between the second outer edge and the central tube. The first wing and the second wing each have a plurality of triangular cut outs 64, 66. In this manner weight and cost are reduced. Further in this manner movement of the head in water is facilitated.

(18) Further provided is a plurality upper notches 70. The upper notches are provided in the upper edge. In this manner securing contact with brake wheels and other wheels in the railroad industry is facilitated. A plurality lower notches 74 is also provided. The lower notches are provided in the lower edge. In this manner secure contact with ropes in the barge and maritime industry are facilitated. The upper and lower notches all have a radius of curvature of 0.125 inches, plus or minus 20 percent.

(19) An alternate embodiment of the present invention 100 is shown in FIG. 9 which illustrates the handle 106, the head 104, and the wing which, in this embodiment, is a single wing 108.

(20) As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

(21) With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(22) Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
