Definitions

  • the present invention is directed to a knife, and more particularly to a replaceable blade for a knife, and to a tape measure.
  • a workman In order to cut plaster or other boards to a desired width, a workman will often use a knife of the type having a replaceable blade together with a tape measure of the type which is extendable and lockable and which has a hooked portion at its free end, instead of marking the board for cutting.
  • the hooked part of the tape is either placed over the upper edge of the blade and held in position by the workman placing his thumb on top of the tape or simply abuts the face of the blade and is held in that position by the workman.
  • the other hand is used to grasp the tape measure housing and then both hands are drawn down the plasterboard or the like, applying pressure on the blade so as to cut into the board. This is a very quick method, since it obviates the need for drawing the line of cut beforehand.
  • US-A-4255856 discloses an attachment for a utility knife which is fitted into the handle of the knife adjacent the blade, the attachment having a slot for receiving a tape measure.
  • GB-A-2153283 discloses a "survival" knife which has an orifice in its blade to which can be fixed various tools, for example hooks to form a harpoon.
  • a blade for a knife, characterised in that the blade has a pair of adjacent slots for receiving the hooked part of the free end of a tape measure adapted to be received in the slots.
  • a knife of the type having a replaceable blade comprising a handle and a blade, characterised in that the blade has a pair of adjacent slots for receiving the hooked part of the free end of a tape measure adapted to be received in the slots.
  • the hooked end of the tape measure may be located in the slots in the blade, and does not need holding in place by the workman during cutting of the board.
  • the slots are preferably elongate apertures in the blade, and may be parallel to the edge of the body of the knife adjacent to the blade. Alternatively, the slots may be provided at some other angle, for example, parallel to the upper and/or lower edges of the blade.
  • a replaceable blade for a knife and a tape measure provided with a hook end part characterised in that the blade has a pair of adjacent slots and in that the hooked end part of the tape measure is adapted to be received in the slots.
  • the invention further includes a tape measure comprising a tape having an end part with a hook on one side only, characterised in that the hook is bifurcated to form a pair of hook portions on either side of a slit extending the full length of the hook portions, whereby the hook end part is receivable by a blade having a pair of adjacent slots.
  • the tape is more securely held in position when the hooked part is passed through the blade, travel of the blade along the tape in use being inhibited.
  • FIG. 1 A first example of a knife 1 of the type having a replaceable blade 2 is shown in Figures 1 and 2.
  • the blade 2 has a pair of adjacent slots 31,32 which are parallel to the edge 4 of the handle 5 of the knife 1 adjacent to the blade 2.
  • a double hook end part 44 of a tape measure 7 is provided with two hooks 45,46 adapted to pass through the slots 31,32.
  • the workman passes the two hooks 45,46 of the tape measure 7 through the respective slots 31,32 of the blade 2, and draws the tape out to the required length.
  • the tape is then usually locked at that length by means of a locking device commonly provided on the body of such tape measures.
  • the workman is then free to apply full pressure to the plasterboard or the like to be cut, since he is not required actively to hold the hooked end part 44 of the tape measure 7 in position on the blade 2.
  • Using his other hand to hold the tape box (not shown) so that some tension is present in the tape 7, an accurate cut is quickly and easily achieved.
  • the bridge portion 47 between the slots 31, 32 prevents the blade 2 from being able to move along the length of the tape during cutting, and so secure locking is ensured.
  • the provision of the two small slots 31,32 also serves to reduce weakening of the blade to a minimum.
  • the slots 31,32 may be positioned at other angles. Examples of such other orientations are shown in Figures 3, 4 and 5.
  • the slots 31,32 are provided in the blade 2 such that the slots 31,32 are parallel to the upper edge 8 of the blade 2.
  • slots 31,32 are provided at a non-zero angle to the edge 9 of the body of the knife adjacent to the blade 2. With the slots 31,32 in this position, in use, the tape is able to be used by the workman so as to check the accuracy during cutting whilst preventing the sharp edge of the tape itself from cutting into the plasterboard. In addition, the likelihood of the blade snapping is kept to a minimum.
  • Figure 5 shows a blade 2 wherein slots 31,32 are again provided at a non-zero angle to the edge 9 of the body of the knife adjacent to the blade 2, but in a different orientation to the slots 31,32 shown in Figure 4.
  • the hook end part 44 of the tape measure should protrude somewhat from the end of the tape so as to leave a substantially rectangular gap 48 between the hooks 45, 46 and the square end 49 of the tape.
  • the hook end part 44 has a cut-out 50 which accommodates the bridge portion 47 of the blade. This cut-out 50 preferably extends beyond the free end 49 of the tape so that the blade can be tilted relative to the tape, ensuring that the hooks 45,46 can be easily inserted into the slots 31,32.
  • a reinforcing member (not shown) may be clipped to the upper edge of the blade so as to provide increased strength and rigidity.
  • This member is elongate and is provided with a channel along its length which accepts the blade in use.
  • the reinforcing member may be formed integrally with the blade.
