Definitions
- the invention relates to a tool holder with at least one tool as an accessory to a power-operated device that fulfills a work function, into which the tool holder must be inserted during commissioning or use of the device, and from which it can be removed for use of the tool.
- a power-operated device is understood to mean any power-operated device, for example a simple work device operated by muscle power, in particular motor-driven or pressure-medium-operated devices.
- Various tools are required for the maintenance, cleaning or modification or attachment of an additional device.
- the tool screwdriver, wrench, spark plug wrench in fuel-operated devices, etc.
- the placement of one or more tools on the device entails the risk of loss, since the tool does not perform any function there.
- the brush cutter can also be used when the tool holder is removed. there is no compelling reason to return it to the storage location after using the tool.
- Work function includes only the area of actual work execution with a facility following the preparatory work to perform a job. This includes starting or switching on an engine of the facility, furthermore holding or guiding the facility during the work process, that is to say those minimum activities which are absolutely necessary even for the simplest execution of a facility to carry out the work.
- the object of the invention is to provide a tool holder with tools as an accessory to a power-operated device, without which, in its second type of use, even with the simplest design of a device, the work to be performed cannot be carried out.
- this object is achieved in that the removable tool holder is designed as an operating part to be used in the device for its commissioning or use, a component of the device which is absolutely necessary for the exclusive exercise of the work function.
- tools are therefore inseparable from an operating part which is absolutely necessary even in the simplest version.
- Assigned part of the facility The design of the facility itself remains essentially or completely unchanged. The training of separate recordings and additional elements after the State of the art does not apply.
- the tool holder in addition to the actual tool holder function, the tool holder, as a second function, therefore also fulfills the active function of a necessary operating part for mere commissioning or use, replacing the usual operating part. Design changes to the device are at most necessary to be able to easily assemble and disassemble the operating part formed by the tool carrier.
- the loss of the tool or tools is of course practically not possible, since after a repair with the tool that occurs during work or operation, the work can only be carried out again after the operating part has returned to the power-operated one Device has been installed.
- the tool or tools are designed so that they do not impair the usual basic shape of the operating part, so that there is no change in the handling and usability of the device.
- Tools for the continuous use of which tools are required, are called simple cutting or sawing tools, such as scythes, sickles, pull saws, hand saws or the like. With such tools, it is repeatedly necessary to sharpen the cutting edges or teeth.
- the or a handle without which the implement cannot be used, can therefore be designed to be removable according to the invention and as a tool holder be designed for a grindstone, one or more files, etc.
- the tool carrier can represent a part of a starter of the motor-driven device that can be actuated by muscle power.
- the equipment is fuel-operated, such as chainsaws, lawn mowers, small boats with an external engine, etc., which very often have starter cables
- the operating part that acts as a tool holder can be the starter handle required at the free end of the starter cable.
- the tool carrier can be integrated, for example, in the kick start lever.
- electrically operated or electrically started devices it can also be formed by the control handle of the electric motor. It is also conceivable to design an operating lever of a pressure medium-operated device as a tool holder.
- the operating parts may also be absolutely necessary for the use of the power-operated devices.
- the handles of simple tools mentioned but such operating parts which are absolutely necessary for the application are usually also present in motor-operated devices in the form of carrying, holding or guide handles, pedals etc. Is it about portable devices that have a bracket or the like. have, for example around a chainsaw, it can therefore also be provided that the tool carrier is formed by a part of the bracket.
- each operating part can represent a tool holder, so that a larger range of tools is available.
- a preferred embodiment of such a tool carrier provides, according to the invention, that the tool carrier has at least one receiving part which is approximately U-shaped in cross section, with at least one end of the receiving part having a pivot axis mounted in the two side webs, on which at least one tool is pivotally mounted. Similar to pocket knives, several tools specific to the device, i.e. a tool set, can be accommodated in the U-shaped receiving part according to this embodiment. A doubling of the tools to be accommodated can be achieved if the tool carrier has two receiving parts which are approximately U-shaped in cross section, the bottoms of which are formed by a common central web.
- the tools arranged in the tool holder are, for example, basic tools, such as several sizes of simple screwdrivers, Phillips screwdrivers, Allen keys and device-specific tools.
- this can be an electrode distance measuring gauge, a wire brush, in the case of a chain saw, a file for sharpening the chain teeth, etc., a plier-like cutting tool, a stripping device, etc. for electrically operated devices.
- at least one end section of the tool carrier is shaped as a socket wrench.
- a two-armed lever is mounted on the pivot axis, the arm projecting into the receiving part rests on each tool and the arm protruding from the receiving part as a pivot lever for the folded tool or tools.
- the inner lever arm presses the tools at least so far from the U-shaped receiving part that they can be gripped comfortably, the tools not required being folded in again.
- the connection between each fastening section of the tool carrier as an operating part and the associated part of the functional element of the power-operated device can be designed in a preferred embodiment as a bayonet lock, which is optionally acted upon by an elastic element in order to avoid the unwanted rotation.
- the tool holder which acts as an operating part, can be made of any suitable material.
- any desired shape and low weight can be achieved by injection molding particularly fiber-reinforced, high-strength thermoplastics, such as glass or carbon fiber reinforced polyamides.
