Definitions

  • the invention relates to a product and process as per the preamble of the independent claims.
  • a hand tool is any tool that is not a power tool - that is, one powered by hand (manual labour) rather than by an engine.
  • multitool or “multi-tool” refers to any one of a range of portable, versatile hand tools that combines several individual functions in a single unit.
  • US 4741059 A (PAN YAU ZUNG ) 03.05.1988 discloses a combined tool unit constructed to be disassembled and reorganized into various independent tools.
  • the tool unit includes a cylindrical hammer portion which can be received between a pair of hand grips of a tongs portion in the storage position of the tool unit.
  • the hammer portion can be fixedly mounted on the closed jaws of the tongs portion to form an independent hammer.
  • a saw blade can be removed from one of the hand grips of the tongs portion and locked into one end of the hammer portion to form an independent saw.
  • a screwdriver bit can be removed from another end of the hammer portion and locked into the same end of the hammer portion where the saw blade can be locked, to form an independent screwdriver.
  • the tongs when disassembled from the hammer portion can be used as a conventional pair of pincers.
  • the hammer portion when disassembled from the tongs portion can be used as a knife by sliding a knife blade, which normally resides in a groove of the hammer portion, outwardly therefrom to thereby form an independent knife.
  • the technical problem is to seek an alternative to the known product and process which provides the same or similar effects or is more cost-effective.
  • a preferred embodiment of the invention includes a screwdriver, pliers, and hammer.
  • the screwdriver and hammer may be employed separately without having to reconfigure the multitool.
  • the screwdriver handle and hammerhead may be optimized independently in view of their respective purposes - such as by combining a heavy-duty claw hammer with a cabinetmaker's screwdriver possessing a light wooden or rubber handle for improved grip and comfort. This contrasts with the background art, where the hammerhead essentially doubles as a screwdriver handle.
  • the pliers receiving the screwdriver shaft With the pliers receiving the screwdriver shaft, the latter may remain protruding from the handle when the multitool is assembled for storage or transport, instantly ready for use once the screwdriver is detached from the pliers.
  • the length of the shaft is by no means limited to the size of the handle or hammerhead, greatly increasing the resulting screwdriver's range of applications. Since the hammerhead may take the form of a massive body, it may be safely and easily attached to the pliers by means of an orthogonal setscrew rather than the multipiece arrangement known from the prior art, which incurs the risk of small parts getting lost.
  • the multitool even while fully assembled, may serve as a long-handled hammer.
  • the invention provides for a multitool that is ergonomic, sleek, and highly stable, all while retaining the functionality and performance of the individual tools it encompasses.
  • Figure 1 illustrates the basic components of a multitool: a screwdriver shank or shaft (11), handle (15), hammerhead (21), and pliers (12).
  • the shaft (11) has lengthwise opposing ends formed into a flat blade (13) and a double blade (14), respectively.
  • Figure 2 illustrates the assembly of a screwdriver.
  • the handle (15) has a coaxial bore for receiving the shaft (11), the bore and shaft (11) having complementary hexagonal cross-sections.
  • the shaft (11) may thus be inserted coaxially into the bore in either orientation such that either the flat blade (13) or double blade (14) protrudes from the orifice (16 - Figure 1 ).
  • the shaft (11) and handle (15) will interlock against relative rotation such that the screwdriver may be employed without further fastening means.
  • the hammerhead (21) has an eye (22) for receiving the engaged jaws (18) of the pliers (12) such that the latter may serve as a helve or grip.
  • the joined levers (17) that constitute the pliers (12) need simply be pivoted such that their jaws (18) mutually engage and can be inserted into the eye (22), resulting in the hammer of Figure 3 .
  • the hammerhead (21) further has a setscrew with a head (23) adapted to be driven, as depicted, by the flat blade (13) of the shaft (11). To allow it to sit flush with or below the surface of the hammerhead (21), said screw head (23) is countersunk into the hammerhead (21).
  • FIG 4 shows the resulting screwdriver and hammer, each assembled.
  • the levers (17 - Figures 1 and 2 ) jointly bear an outer thread (19) across from their jaws (18) that, in the configuration depicted, mates with an inner thread (20) of the bore orifice (16 - Figure 1 ).
  • the screwdriver may thus be attached to the hammer by screwing the handle (15) onto that outer thread (19), finally resulting in the multitool (10) of Figure 5 .
  • the screwdriver shaft (11) is received between the pliers (12) which, to accommodate the shaft (11), are grooved complementary to it.
  • the invention may be applied, inter alia, throughout the tooling industry.
