Definitions

• the present invention relates to a multi-function hand tool.
• the aim of the present invention is to provide a multi ⁇ function tool which combines a plurality of functions which are currently divided among a plurality of distinct tools.
• an important object is to combine several different tools in a single tool.
• Another important object is to provide a combination of tools which allows to perform the most common and frequent hobbywork or domestic repair operations.
• Still another object is to provide a tool which can be easily used by a scarcely expert person.
• a multi-function hand tool characterized in that it consists of a pair of pliers with two arms which are mutually pivoted in a non-median point and which define two sections, a short one and a long one respectively, the two short sections defining two co-operating grip jaws with adjustable opening, provided with a cutting region, one of said jaws extending and expanding so as to define a hammer ⁇ head opposite to the grip region, said two long sections constituting the handgrip of the pliers and being hollow, divided into two parts and containing other tools such as screwdrivers, files and/or cutting blades.
• figure 1 is a complete view of the tool according to the invention in closed configuration
• figure 2 is a partially sectional view of the front part of the tool, illustrating the hammer-like head
• figure 3 is a perspective view of the tool with the handgrips divided into their component parts and illustrating the tools contained therein
• figure 4 is a detail view of the front part of the tool, with the grip jaws open
• figure 5 is a view of the assembly of one of the tools onto one of the separate sections of the tool handgrip
• figure 6 is an exploded view of the configuration of the hammer-like head.
• the tool according to the invention substantially comprises a pair of pliers generally indicated by the reference numeral 1 and formed by two arms, respectively 2 and 3, which are pivoted at an adjustable fulcrum 4, each of said two arms defining two sections, respectively a longer one and a shorter one.
• the two short parts constitute a pair of grip jaws having a toothed flat front region 7 acting as clamp, a second toothed and curved region 8 acting as pipe wrench and a pair of opposite blades 9 acting as parting tool.
• Said jaw 5 is provided with a flat metallic blade associated with the arm 2 by embedding its end in an internally hollow cylindrical element 10 made of plastic material having a second portion 11 connected to the element 10 by screwing and adapted to constitute the handgrip of tools such as screwdrivers 12 and 13 or cutting blades 14 which are generally contained in .the hollow portion 15 of the element 10.
• the jaw 6 is also metallic and flat and then connects to a cylindrical body 16 having the function of a hammer ⁇ head.
• Said cylindrical body 16 has a cylindrical region with reduced cross section 17 which is contained in a sleeve 18 made of plastic material which constitutes the front end of the arm 3 and extends into a flat region 19 composed of two blades 20 and 21 wherewith the jaw 5 is inserted and which then merge into a second hollow cylindrical element 22 which constitutes the second handgrip of the pliers.
• An end cap 23 is screwed to said second hollow cylindrical element 22, and a tool, such as for example a file 25, can be accommodated in the hollow part 24.
• the adjustable fulcrum 4 derives from the combination of two S-shaped slots 27 provided on the blades 20 and 21, the ends 28 and 29 of said slot 27 being adapted to retain in place a cylindrical pivot 30 rigidly associated with the jaw 5.
• FIG. 1 illustrates the configuration of the S-shaped slot 27 so that it can firmly react during the tightening of the jaws 5 and 6.
• Figure 5 illustrates the association between the cutting blade 14 and the second portion 11 of the cylindrical element 10 so that it constitutes the handgrip of the tool.
• a ring 32 which normally abuts against the handgrip, is screwed onto the threaded tang 31 of the second portion 11.
• Said tang 31 has a recess 33 and a radial notch 34 adapted to accommodate the end 35 of the blade 14, said cavity 33 being also adapted to rigidly couple the handgrip to each screwdriver 12 or 13.
• Said end 35 has, on the side to be inserted in the notch 34, a saw-toothed region 36 shaped exactly like the thread of the tang 31, so that the blade 14 is fixed to the handgrip 11 by moving the ring 32 toward the end of said tang 31.
• the tool as illustrated hereabove is therefore the result of the combination of some metallic parts, i.e. of the jaws 5 and 6 and of the hammer-like head 14, which is monolithic with the jaw 6, and of parts made of plastic material.
• FIG. 15 illustrates a different configuration of the hammer-like head of the invention.
• the cylindrical body 16 can be conveniently screwed onto an inner element 37 having a first threaded portion 38 extending into a nail-removing element 39 which is encapsulated by the cylindrical body 16.
• Said cylindrical body 16 can be conveniently metallic or made of a hard plastic material, assuming the configuration 16a, which is particularly suitable for striking objects which might be damaged by a metallic head.
• the multi-function tool has the function of a pair of pliers, of a pipe wrench for pipes of various diameters, of a parting tool with cutting blades, of a hammer, and has further tools contained in the hollow handgrips.
• the combination may obviously be, as already mentioned, further integrated by tools besides those already mentioned.
• pivoting system between the arms 2 and 3 can be of any suitable type.
• the combination between metallic jaws and handgrips made of plastic material is particularly convenient from the productive point of view.
• the dimensions may be any according to the requirements.
