Definitions

• the present invention relates to a tool and more specifically to a hand-held tool, in which there is preferably a selection of blades or similar, permitting several different operations, with the aid of which many tasks can be performed in a dextrous manner.
• the general principle of the said known products is implemented using the 'pocket-knife principle'.
• the blades which may be knife blades, or possibly screwdriver blades, or possibly even blades required for removing a bottle cork, are located folded inside protective shells. One problem is then to pull the blade out of its tight location. Another problem is the poor durability of the construction if the task requires a great deal of force.
• the tool When referring made mainly to a tool intended for professional use, one important factor is that the tool must also be sufficiently durable to perform tasks requiring a great deal of force. Another factor will certainly be for the tool to also include means for performing such work demanding more force.
• the invention is intended to create a versatile tool suitable for professional use, with the aid of which many different tasks can be performed, and which is also suitable for performing tasks requiring force.
• FIG 1 shows one well-regarded embodiment of the invention, with part opened
• FIG 2 shows another part of the tool of Figure 1 opened
• Figure 3 shows the tool according to the invention closed in the pocket position.
• Figure 1 shows the tool according to the invention partly opened. In fact, this may be the 'normal' position of the tool according to the invention, if the wrench head shown in the left-hand end were to be fixed in this position.
• the body 2 of the tool 1 is made from a sturdy material, particularly from a metal, such as steel or aluminium.
• various work blades such as the knife blade 4 shown in Figure 2 are pivoted inside the body to be rotatable around a suitable pivot pin, such as that marked with the reference number 3.
• the other conventional work blades are, for example, straight or crosshead screwdriver blades, files, or scissors.
• numerous different applications can be made, in which the number and type of the blades vary.
• an adjustable-wrench-type work blade 6 is located rotatably in the tool according to the invention.
• the adjustable-wrench component 6 can be either fixed relative to the body, or set rotatably.
• the rotatable situation brings its own advantage; in that, in the position that is a straight extension of the body 2, the longest possible torque arm will be obtained for operating the wrench, whereas in the other positions the adjustable wrench can be set in an appropriate position to perform the intended task.
• the adjustable wrench 6 incorporates a fixed jaw 7 and a moving jaw 8, as well as an adjustment screw 9, with the aid of which the moving jaw is moved to the desired position.
• the shape of the jaws 7 and 8 of the adjustable-wrench component 6 of the tool 1 according to the invention also facilitates access to quite difficult locations, as the points of the jaws are very thin. It is obvious that the shape of the jaws also affects their durability, for which reason excessive narrowing is a poor alternative.
• the adjustable-wrench component 6 can be folded on top of the body 2 of the tool 1 , in such a way that the tool can be comfortably held in the hand. All in all, the diameter of the tool according to the invention is clearly greater than that of tools referred to in the description of the prior art, so that it provides a firm grip while durability problems will not arise from a lack of material.
• Figures 1 - 3 also shown a handy way of ensuring that the adjustable-wrench component 6 remains in place. This is because there is a spring-like component 10 on top of the body 2, which holds the adjustable-wrench component in place with a small spring force, by resting on the moving jaw 8 of the adjustable- wrench component 6. The jaw 8 is screwed to a suitable position by using the screw 9, so that the moving jaw 8 will lie under the spring component 10.
• the adjustable-wrench head should be set in a position 90 degrees from the position according to the present invention, as such a position would be clearly easier to implement than the position according to the present invention, in a case in which two sides plates are used according ' to the prior art. In this case, however, it is precisely the operation of the tool and its dextrousness and comfort that have been considered, by locating the adjustable-wrench head in the manner shown.
