Abstract

A multi-purpose tool, partly foldable, useful as a hammer/pick, probe/ruler, knife/saw, spade/trowel, and even as a bottle-opener. Various embodiments are characterized by degrees of folding to compact stowed form and of unfolding to particular use configurations.

Claims

1. Multi-purpose hand tool comprising

substantially straight handle means having a haft and a grip portion and having digging means pivotally mounted on the haft portion in deployed position and alternatively in stowed position,

clevis means protruding from the haft portion, flanking the digging means, and carrying a pivot pin pivotally mounting the digging means,

the digging means having a positioning bore transversely therethrough substantially parallel to the pivot pin, and

the clevis means having pairs of aligned bores therethrough parallel to and flanking the pivot pin forward and aft thereof, and a locking pin insertable through either pair of bores,

wherein the digging means is thereby adapted to align with one of the clevis bore pairs in normally deployed position and to align with the other of the clevis bore pairs in alternative stowed position and be locked in the selected position by insertion of the locking pin therethrough.

2. Multi-purpose hand tool according to claim 1, including

a locking pin fitting through the positioning bore and through either of the bores in the clevis means to secure the blade in deployed or stowed position as desired.

3. Multi-purpose hand tool according to claim 1, including

impact means normally protruding substantially perpendicular to the haft portion and comprising

a hammer head protruding in a forward direction, and

a pick head protruding in an aft direction therefrom.

4. Multi-purpose hand tool according to claim 3, wherein

at least one such head is pivotally mounted relative to the handle means and thereby is alternatively foldable from its normally protruding deployed position into a stowed position against and partly overlapping the handle means.

5. Multi-purpose hand tool according to claim 4, including

locking means adapted to lock such pivotal head in its normally deployed position, and

locking means adapted to lock such pivotal head in its alternative stowed position.

6. Multi-purpose folding hand tool comprising handle means at one end thereof digging means including a trowel blade having a base, mounted on the handle means and convertible between deployed and stowed positions, adapted inn stowed position to function as a bottle opener by reason of spacing of the base of the trowel blade from the handle means sufficiently to enable the top of a bottle cap too be engaged by the blade base and the rim of the cap to be engaged by the handle means as a fulcrum, whereby pivoting of the bottle about such fulcrum is effective too pry off the cap.
