Abstract

The 'Safe-Accurate-Secure' cutter is a cutting tool designed to cut through layers of shrink-wrapping protecting and binding parcels and boxes. It is a safe, accurate and secure alternative to knives and other cutting implements. Cutting blade E is encapsulated in a two section casing, C and D. Section C, (not shown), is similar to section D but without the castings which house the cutting blade and spare blades. The two casing sections are locked together to form the tool. Only the well protected cutting areas L and M of the cutting blade are left exposed. Motorised blades, powered by a rechargeable battery, are disclosed.

Description

2363750 The S A S (Safe-Accurate-Secure) Cutter This invention relates to

a tool for cutting.

This invention relates to a cutting tool primarily designed to cut through layers of shrink-wrap- ping protecting and holding together parcels, boxes, goods and other materials, in stacks, on pallets.

This invention relates to a cutting tool aiming to replace knives and other cutting implements in its range of uses.

Knives and most other cutting tools can easily penetrate beyond the material intended for cut- ting and can damage goods therein or injure hands and fingers.

Knives and most cutting implements if incorrectly handled, or by accident, can injure the user, or a bystander and can be used as weapons to cause injury.

This invention relates to a cutting tool designed to offer the purchaser and user the maximum in safety, accuracy and security both in use and in storage.

This invention will enable the user to lift and cut materials intended for cutting; off the materi- als protected or secured, thus ensuring the protected goods or materials sustain no damage from cutting.

The design of this invention will also enable the user to cut fast, safely and securely through materials other than shrinkwrapping, such as: string, tape straps (non metal) cloth, flexible plas- tic (U P V C) wrappings and many other tensioned flexible materials.

This invention will enable the user to cut by pull or push action and in any direction See the drawings provided, which illustrate pull and push action cutting (figure 2 and figure 3) in this case shrinkwrapping protecting parcels on a pallet is being cut.

Referring to the drawings (figure 1) the S A S cutter comprises a two section casing "C" (not on the drawing) and "D" "D" section of the casing houses a single blade "E" which has two curved cutting areas "L" and "M" one at each end of the blade Section "D" also has a compart- ment to house spare blades ("F' on the drawing of figure 1).

The two casing sections "C" (not on the drawing) and "D" are secured together by bolts G 1, G 2 and G 3 which are driven through holes in section "C" into threaded corresponding holes in section "D", assuming Both sections of the casing or at least casing section "D" is made of metal or alloy If softer material is used for the casings then steel nuts can be embedded in the ap- propriate position in the outer face of casing section "D" "G 1 " bolt, which will also hold cover 7 " in position, will be a hand-tied bolt so as to allow the cover to be opened or closed by hand.

Section "Y" of cover "Z" will slide into incision "V" of the casing when in the open position.

The cover may also be of a different construction, unattached, shaped to fit and lock over the cutting area of the tool by clip on action.

The casings ideally should be made of cast alloy, metal or good quality plastic.

Two shallow compartments will be cast in the inner part of section "D" of the casing.

One (compartment "F') will house the spare blades and the other (compartment "E") will house the cutting blade, see drawing in figure 1.

The compartment "E" casting in section "D" of the casing will be in the exact shape of the (cut- ting) blade and will allow no movement of the blade when the blade is in position.

The position of casting "E" is such that when the two casing sections are locked together, the cutting blade installed in casting "E" is totally covered with the exception of the cutting areas "L" and "M" of the blade, which are left exposed.

Importantly please note that the corners (or edges) of the cutting areas on the blade, must also be covered by the casing.

The two casing sections ("C" and "D") can also be cast as "male" and "female", partially or totally interlocking, thus requiring just one bolt to hold them tight together.

The perimeter of the casing is circular with the exception of the base which is flat, see "I" and "F in the drawing in figure 1 The circular part will have a grooved rounded edge Flat base "re is formed by the combined thickness of the two casing sections when these are locked to- gether.

The single (and only) opening "K" leads to the two cutting areas "L" and "M" "L" cutting area is for inward or downward cutting, by pull action "M" cutting area is for outward or upward cutting, by push action.

Features such as point "A" and "B" of the casing are designed so as to enable the user to follow a line of cut with a degree of accuracy This is possible by using point "A" as guideline when cutting inwards-downwards and point "B" as guideline when cutting outwards-upwards, see drawings in figure 2 and figure 3.

A specific embodiment of this invention is described by way of example with reference to the accompanying drawings in which: figure 1 shows in perspective section "D" of the casing with the main features of the tool Casing section "C, (not on the drawing) is identical to casing sec- tion "D" in shape, but without compartments "F' and "E" and faces in the opposite direction to casing section "D".

Figure 2 shows in perspective the tool (S A S Cutter) in position lifting and cutting through layers of shrinkwrapping, which is protecting and holding together parcels stacked on a pallet.

In this instance the cutting is done outwards or upwards, by push action, using point "B" as guideline for accuracy.

Figure 3 shows in perspective the tool lifting and cutting as in figure 2, but inwards or down- wards by pull action, using point "A" as guideline for accuracy.

Figure 4 shows in perspective the tool with cover "Z" in the open position (straight lines) and closed position (dotted lines).

Figure 5 shows in perspective the tool with cover 'ZX" in the open position (straight lines) and in the closed position (dotted lines).

Caution Children should not use the S A S Cutter, even in a mini version, unless supervised by an adult.

Amendments to the claims have been filed as follows CLAIMS 1) The S A S Cutter can cut two ways, forwards and backwards, safely and with accuracy by guiding its line of cut, as it moves along a premarked route, using points "A" and "B" as a guide.

2) This invention can cut two ways, as in claim 1, facing in the same direction and in the same position in the user's hand.

3) Visibility towards the line of cut and guidance is not obstructed whether the tool is used for forward or backward cutting.

4) The S A S Cutter is a tool ideal for workplaces where safety and security is of pri- mary concern It cannot be used as a weapon, in the way of a knife and it will be of little or no use for cutting tasks other than those it is intended for.

5) Once protective materials, such a shrink-wrapping, is lifted into a cutting area of the tool, the base of the tool can be lowered to a flat position over the protected ma- terial or it can be tilted to lift the opening to the cutting area and points "A" and "B" away from the surface of the protected materials thus eliminating the possibil- ity of such materials sustaining damage during the cutting process.

6) The anti-clog design of the S A S Cutter will ensure that materials being cut in ei- ther of the two cutting areas will not clog inside such area of the tool whether it is flat on its base or tilted and however irregular or incorrect the movement of the hand is while using the tool.

This feature will ensure flexibility of movement both for the tool in use and the hand using it.

7) The tool's opening to the cutting area is in an ideal position to allow the base of the tool to glide over the surface of materials under protection without damaging these while it cuts through protective materials.

This feature will provide stability and ease of direction for the tool.

8) The S A S Cutter with or without the use of an attachment will have a longer reach cutting high up, low down or at distance from any of its competitors.

This feature is based on the tool's ability to transfer or hook and cut materials in reverse.

Example: Lets assume the last distant item to be cut is a loose strap.

9) The exposed parts of the cutting blade are well protected This will help prolong the "life" and sharpness of the cutting blade 10) The design of the handle and its position ensures good grip, better vision, ease of direction and better guidance towards the line of cut.
