Definitions

  • the present invention relates to a knife, particularly suitable for skin-diving activities, but usable as well for other activities.
  • Conventional knives for skin-divers comprise, in a thoroughly traditional fashion, two separate members, i.e. a sheath, made usually of plastics material, provided with means for connection to a part of a skin-diver's equipment, and a knife comprising a steel blade and a handle, usually of plastics material, secured to the tang of the blade.
  • the object to the present invention is to provide a knife, particularly suitable for skin-diving activities, comprising only two members, i.e. a blade provided with an integral extension forming a tang having substantially the same length as the blade, and a tubular member inserted over said tang and said blade in such a manner as to be slidable from a first position wherein it covers the blade and acts as a sheath, to a second position wherein it covers said tang and acts as a handle for the blade which is then uncovered.
  • Both the blade and the tubular member are provided with co-operating releasable locking means for firmly holding said tubular member in both said first and second positions.
  • the knife is equipped with means for connection in a quick-releasable manner to an element of a skin-diver's equipment as, for example, to his ballast-belt or harness.
  • numeral 1 denotes the blade of the knife.
  • Said blade 1 is provided with a tang 2 in the form of an integral extension having at least the same length as the blade 1.
  • Said tang 2 is, in turn, provided at the free end thereof with a ring-shaped extension 3 for the purposes which will be described later.
  • the tubular member 4 which is made, preferably, of plastics material, is formed with a tubular passage 104 having a cross sectional shape which is substantially complementary to the cross sectional shape of the tang 2, and provided in proximity of the two ends of the tubular passage 104 with two slots 204, 304.
  • the blade 1 is provided with a notch 102 at the region merging with the tang 2.
  • the blade 1 is provided at said region with a locking member 5 comprising, as best shown in Figure 3, a bracket-like portion 501 comprising a through-hole 502 which co-operates with a pin 103 passed through the blade 1.
  • a resilient tongue 503 Connected to the bracket portion 501 is a resilient tongue 503 provided at one end thereof with a detent 504.
  • Said detent 504 can fit into the slots 204, 304 of the tubular member 4, and it may be released from said slots by depressing its end inwards in the direction of the arrow P of Figure 1 or 2, so as to force it partly into the notch 102.
  • the annular extension 3 of the tang 2 is intended for fastening with a member 6 to be connected to the skin-diver's harness.
  • Said member 6 may be, for example, in the form of a resilient hook-like member 601 to tbe inserted into a complementary member worn by the skin-diver, or it may be in the form of a "velcro" fastening device, or any other suitable device.
  • a simple and particularly suitable device is shown in Figure 4.
  • the tubular member 4 comprises, in the two larger outer faces thereof, two grooves 401,402 extending longitudinally over the entire length thereof.
  • the tang 2 comprises a fork-like extension 201 parallel thereto, the free end of which may be inserted into either one of the two grooves of the tubular member 4, for example, in the illustrated case, the groove 401.
  • the fork-like extension 201 may be easily inserted, due to its resiliency, over a belt 7 forming a part of the skin-diver's equipment, so as to hold the knife. Said extension may be disengaged from the belt 7 as easily, and the knife may be turned into its operative condition by sliding the tang 2 into the tubular member 4 and by simultaneously sliding the extension 201 into the groove 401.
