DESCRIPTION

(8) Referring to FIG. 1 the pocket tool shown comprises an elongate handle portion 1, an elongate tool carrier plate 2, and snap-fit or screwed metal bushing assembly parts 3, 4 which fit through apertures 7 and 8 in tool carrier plate 2 and handle portion 1 respectively. In this manner the handle portion and tool carrier plate are pivotally connected for rotation about axis X.

(9) The tool is provided with a detent mechanism comprising two diametrically opposite miniature spring-loaded ball plungers 22 on the upper face of handle portion 1 which engage respective detent recesses 20 (FIG. 2) disposed in a circular array in the underside of tool carrier plate 2. The detent mechanism defines eight indexed angular positions of the tool carrier plate on the handle portion, with an interval of 45 between them.

(10) The tool carrier plate 2 is generally rectangular and has a rectangular array of tool heads at its corners, namely three screwdrivers heads 13A (small Phillips), 13B (flat-bladed) and 13C (medium Phillips) and a fingernail-cleaning tool 14, and also a wire stripper 15 cut-out portion formed in one of its shorter sides. These tools are labelled with indicia as shown.

(11) The elongate handle portion 1 includes a carabiner clip portion 5 and has opposed stepped spanner faces 6 of successively smaller spacing at the inner end of the internal periphery of the clip, terminating in a thread cutter/wire stripper blade 12 (labelled CUT on the handle portion 1 in FIG. 1). Thread cutter/wire stripper blade 12 is located in a square recess and its cutting edge projects slightly over the edge of the recess. When the tool carrier plate 2 is transverse to handle portion 1 (e.g., as shown in FIG. 5 or FIG. 6) the cutting edge is exposed and can be used to cut thread or the like. When the tool carrier plate is aligned with the handle portion 1 as shown in FIG. 3, semicircular cut-out portion 15 overlies the cutting edge of the blade 12 and the end of an insulated wire can be placed in the cut-out portion and rotated about its axis to make a cut in its insulation near its end. The cut length of insulation can then be pulled off. In this manner the blade 12, in conjunction with cut-out 15, functions as a wire-stripper.

(12) It will be noted that the cutting edge of thread cutter/wire stripper blade 12, being located at the interior periphery of the tool, is not liable to cut a user's finger or a pocket in which the tool is kept. Cut-out 15 is too small for a finger. Furthermore, by rotating the tool plate 2 by 180 from the orientation shown in FIG. 3, the opposite end of the tool plate will completely cover the cutting edge.

(13) In a variant the positions of the blade 12 and cut-out 15 can be interchanged, i.e., blade 12 can be located in a recess in tool carrier plate 2 and cut-out 15 can be formed in handle portion 1.

(14) The handle portion 1 has a pry bar cut-out 11 formed in its forward (distal) end and a spoke spanner cut-out 11 formed at the forward end of its right-hand lateral side S1. The remainder of this side has a straight edge and corresponding ruler markings. The forward end of the left-hand lateral side S2 has a serrated box-cutting edge 21 formed therein. Finally, the handle portion 1 has hexagonal spanner apertures 9 formed at its forward end.

(15) The stowed configuration of the tool is shown in FIG. 3, and it will be seen that the rectangular array of tool heads 13A-13C, 14 is longitudinally aligned with respect to the longitudinal axis L of handle portion 1. In this configuration, none of the tool heads protrude beyond the lateral sides of the handle portion 1.

(16) Furthermore, the forward end and rear end of the handle portion 1 (to the left and right respectively in FIG. 3) both extend longitudinally beyond the boundary of said peripheral array of tool heads in the stowed configuration shown in this figure.

(17) Furthermore, it will be noted that the axes of the forward tool heads 13A and 13B are disposed at 45 to and intersect longitudinal axis L at a point forward of rotary axis X and that the axes of rear tool heads 13C, 14 similarly intersect this axis L at points rearward of rotary axis X. This non-radial alignment of the tool head axes enables the tool heads to be deployed orthogonally with respect to the lateral sides S1 and S2 of handle portion 1 with an anticlockwise rotation of the tool carrier plate 2 of 45, as shown in FIG. 4.

(18) In the first deployed configuration shown in FIG. 4, the screwdriver heads 13B and 13C are deployed orthogonally from lateral sides S1 and S2 respectively.

(19) As shown in FIG. 5, a further anticlockwise rotation of tool carrier plate 2 by 45 deploys all four tool heads from lateral sides S1 and S2, tool heads 13B and 14 projecting forwardly and tool heads 13A and 13C projecting rearwardly.

(20) Finally, as shown in FIG. 6, a further anticlockwise rotation of tool carrier plate 2 by 45 deploys a tool head 13A orthogonally from lateral side S1 and deploys tool head 14 substantially orthogonally from lateral side S2.

(21) Thus all four tool heads can be deployed singly or in combination, at an angle of either 45 or (approximately) 90 to lateral sides S1 and S2 of handle portion 1. The tool carrier plate 2, having a major surface exposed on handle portion 1, can easily be operated by the thumb of one hand while the fingers of that hand grasp the handle portion. Thus the tool is suited to a single-handed operation.
