DESCRIPTION:
BRIEF SUMMARY
The invention relates to a tool or set of tools, arranged upon a tool-carrier, for use with power-operated devices.
In this connection, the expression power-operated device is intended to encompass any device driven by power, for example by an engine or a pressure-medium. In devices of this kind, sundry tools are required for maintenance, cleaning conversion and fitting of accessory units. However, it is always a difficult problem to keep the tool (a screwdriver, wrench, spark-plug wrench etc. in the case of fuel-driven devices) handy, so that, on the one hand, it does not go astray and, on the other hand, it is within easy reach and does not interfere with the operation of the unit or with the operator. For instance, the accommodation of one or more tools is a closable container on the device, which is common in a very wide variety of vehicles, involves a risk of losing the tools, since they may not be returned to the container, the container may not be closed, etc. Tools may also be lost if carried by the operator and this has other disadvantages, in that the weight and the amount of room they take up may be troublesome and may also lead to injury.
Also known are pocket-knives comprising a whole series of folding out tools such as corkscrews, screwdrivers, bottle-openers etc., but such tools are intended for general use, not for special appliances. Apart from this, a loose pocket-knife can always be lost since, after it has been used as a tool, it need not be used any further. Similar criteria apply to other multi-purpose tools, such as handles with interchangeable tool-inserts etc.
Now it is the purpose of the invention to provide a tool or set of tools intended for use on power-operated appliances, whereby the danger of loss is practically eliminated.
According to the invention this problem is solved in that the tool carrier is formed by an operating part essential to the starting-up or use of the power-operated device, said operating part being arranged detachably upon a functional element of the said device. As used herein, the term `working function` shall refer to a function absolutely essential to the starting up or use of the particular power operated device and, which further must be provided for such a power operated device, in general, to operate, e.g. delivering electric current to an electric motor.
According to the concept of the invention, therefore, the tools are inseparably associated with an essential, removable operating part of the device. Loss of the tool or tools is practically impossible, since in the event that a repair is carried out while the device is in use or in operation, such use or operation can be continued only after the operating part has been incorporated into the power-operated device again. In this connection, the tool or tools are designed in such a manner as not to interfere with the basic configuration of the operating part and not to alter the method of operation.
The operating part serving as the tool-carrier depends upon the type of power-operated device. In the case of devices operated entirely by muscle-power, the operating part will be a handle or a pedal. Examples of simple implements requiring a tool for continuous use are simple cutting or sawing tools such as scythes, sickles, felling saws, hand-saws, or the like requiring repeated sharpening of the cutting edges or teeth. Thus the, or a, handle, without which the implement cannot be used, may, according to the invention, be made detachable and may be designed as a tool-carrier for a whetstone or one or more files, etc.
In the case of engine-driven devices, the tool-carrier may be a manually actuated part of the starter. For fuel-driven devices such as chain-saws, lawn-mowers, small boats with outboard-engines, which frequently have starter-cables, the operating part acting as the tool-carrier may be the starter-handle fitted to the free end of the starter-cable. Othe fuel-operated devices may have the tool-carrier built into the kick-starter lever, for example. In the case of electrically driven, or ele
