Definitions

  • the invention relates to a tool holder with at least one tool as an accessory to a motor-operated device having a starting element, into which the tool holder must be inserted for commissioning, and from which it can be removed for the use of the tool.
  • a motor-operated device is understood to mean any device that is operated by a motor or pressure medium and is put into operation by means of a starting element to be actuated.
  • 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.
  • Simply placing one or more tools on the device entails the risk of loss if the tool does not perform any function there.
  • the object of the invention is to create a tool holder with tools as accessories and as a component of the motor-driven device necessary for commissioning, a special adaptation of the device for receiving the tool holder being unnecessary.
  • this object is achieved in that the removable tool carrier is designed as an operating part of the starting element which can be actuated by muscle power.
  • tools are therefore arranged inseparably on an operating part of the starting element.
  • the design of the facility itself remains essentially or completely unchanged.
  • the formation of separate receptacles and additional elements according to the prior art is omitted.
  • the tool holder as a second function therefore also fulfills the active function of a necessary operating part for commissioning.
  • Design changes to the device are at most necessary to be able to easily assemble and disassemble the operating part of the starting element 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 device has been installed.
  • the tool or tools are designed so that they do not affect the usual basic shape of the operating part, so that there is no change in the handling and usability of the device.
  • the operating part that acts as a tool holder can be the starter handle required at the free end of the starter rope.
  • the tool carrier can, for example be integrated into the kick start lever.
  • electrically operated or electrically startable 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 carrier.
  • the removal of the tool holder from the device also serves as protection against unauthorized commissioning. It happens that facilities stay in place overnight when work is interrupted, for example, it is almost common in forestry to leave chainsaws in the forest. If the starter handle is removed in the evening, commissioning is only possible after reassembly. The same applies, for example, to boats that may remain unattended on the shore for a few hours.
  • 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 swivel axis mounted in the two side webs, on which at least one tool is pivotally mounted.
  • 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 swivel axis mounted in the two side webs, on which at least one tool is pivotally mounted.
  • a tool set 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., for electrically operated devices, a plier-like cutting tool, a stripping device, etc.
  • at least one end section of the tool carrier is shaped as a socket wrench.
  • a two-armed lever is mounted on the swivel axis, the arm protruding into the receiving part rests on each tool and the arm protruding from the receiving part as a pivot lever for the tool or tools is used.
  • the inner lever arm presses the tools at least so far out of the U-shaped receiving part that they can be gripped comfortably, the tools not required being folded back in again.
  • connection between each fastening section of the tool carrier and the associated connecting part to the starting element of the motor-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 functions as an operating part, can be made from any suitable material.
  • any desired shape and low weight can be achieved by injection molding processing, in particular fiber-reinforced, high-strength thermoplastics, such as glass or carbon fiber reinforced polyamides.
  • a chainsaw is shown as a general explanation as an example of a device 1 according to the invention.
  • This device has a starting element 2 in the form of a starter and carrying or holding handles 3.
  • an extendable starter cable 36 is provided with a starter handle 5, which can be removed from a connecting part 35 fastened to the end of the starter cable 3, 6 (FIG. 8).
  • the starter handle 5 is designed as a tool carrier 4, which carries tools that cannot be removed under normal conditions. If one of these device-specific tools is required, the tool carrier becomes. 4 removed. Since with the factory approved Tool holder 4 of the device 1 of the operating part of the starting element 2 is missing, it cannot be put into operation without mounting the tool holder 4. Since at least one functional test is generally carried out after a repair or maintenance, the tool is thereby stowed almost captively.
  • the tool carrier 4 is therefore approximately T-shaped and has two receiving parts 10 of approximately U-shaped cross section, which are connected by a common central web 15 and form the crosspiece of the T-shape.
  • the two ends of each receiving part 10 are designated by 11 and 12, with an axis 14 being arranged in the two side webs 13 of the receiving part 10 in the end 11.
  • At least one tool 20, 21, 22 is pivotally mounted on each axis 14.
  • the axis 14 is subdivided into two partial axes 14 ', the second end of each partial axis 14' engaging in a tab 33 which is parallel to the side web 13 and is provided only in the region of the end 11 of the receiving part 10.
  • a resilient locking element 29 is provided for each tool, which fixes the tool in the folded position, wherein it snaps into a recess 30 of the tool 20, 21, 22.
  • recesses 34 are formed on the inside of the side web.
  • a further recess 32 is arranged on the tools 20, 21, which are two different sizes of screwdrivers, into which a cam 31 engages, which projects out of the tab 33.
  • the two receiving parts 10 are adjoined on both sides by an end section 27 which is designed as a socket wrench 24, that is to say as a further tool.
  • the center piece 46 of the T-shape of the tool holder 4 forms a fastening section 19 for the detachable connection of the tool holder 4 to the connecting part 35 of the starting element 3, which, as mentioned, is shown in FIG. 8 as a receiving piece of the starting cable 36.
  • the fastening section 19 is provided with two retaining projections 28 of a bayonet lock, which have a curved locking surface. Retaining protrusions 28 with the same curvature are formed on the insertion section of the connecting part 35.
  • the bayonet catch 25 In order to avoid the independent release of the bayonet catch 25, it is acted upon by an elastic element 26 which is inserted into the center piece 46 of the tool carrier at the edge of the receiving opening for the part 35 and is formed, for example, by a foam or foam rubber part. If a through bore is provided in the middle piece 46 as a receiving opening for the part 35, the end section into which the elastic element 26 is inserted can also form a socket wrench.
  • the free end section 27 of the middle piece 46 is also shaped as a socket wrench 24, wherein in the exemplary embodiment shown it is suitable as a spark plug wrench for loosening or fastening a spark plug 44.
  • At least one of the screwdrivers shown can at the same time form an electrode distance measuring gauge, in that its rotary section has the thickness corresponding to the usual electrode distance.
  • a hexagon key is arranged as the tool 22, which, due to its outer edges, latches on the locking element 29 without a recess.
  • its swivel angle is limited to approximately 90 ° by a stop on the largest socket wrench 24, while the smaller socket wrench 24 on the other end section 27 serves as a 180 ° stop.
  • further tools can be inserted, which are not shown, particularly for reasons of clarity.
  • a wire brush in addition to the illustrated chain saw, a file for sharpening the chain teeth, etc. can be provided, in particular as a supplement to fuel-operated devices, since three to four tools can be conveniently accommodated per receiving part.
  • FIGS. 9 and 10 show a further exemplary embodiment in which the tool carrier 4 is formed by a switch handle 8 of an electrically operated device, in which the operating part, that is to say the tool carrier 4, can be removed from a switch 7.
  • the exemplary embodiment is somewhat simplified, so that the tool carrier 4 is provided with a single U-shaped receiving part 10.
  • the end section 27 of the tool carrier 4 is also designed as a socket wrench 24 in this embodiment.
  • three tools 20-22 for example two screwdrivers 20, 21 and a hexagon key 22 are rotatably mounted on the axis 14 arranged in the side webs 13.
  • the tools 20-22 are arranged in the rest position in the cross-sectionally U-shaped receiving part 10, from which they can be folded out.
  • a two-armed lever 16 is likewise rotatably mounted on the axle inserted into the side webs 13, the inner arm 17 of which projects into the U-shaped receiving part 10 and bears against the folded tools 20-22.
  • the outer arm 18 of the lever 16 protrudes slightly from the end 11 and can therefore be operated.
  • the range of motion of the two-armed lever 16 is chosen so that the actuation of its outer arm 18 lifts the tools 20-22 so far out of the receiving part 10 that the ends thereof can be grasped comfortably by hand.
  • the desired tool can be gripped and completely unfolded, while all others can be pushed back into the receiving part 10.
  • the passage opening 37 is designed as a hexagonal opening, so that it can also form a socket wrench for smaller screw nuts.
  • the tool combination can be changed or supplemented, for example the arrangement of a plier-like cutting tool is favorable for electrically operated devices.
  • FIG. 11 shows a tool carrier 4, which forms an operating part in the form of a handle lever and can be provided, for example, for controlling a pressure medium-operated device 1.
  • the tool holder 4 therefore has only one fastening section 19, which for connection has, for example, a fastening bolt 39, which optionally also serves as a pivot axis for the handle lever and is secured by a split pin, and is attached to the starting element, for example, a control valve 9 of the device.
  • the fastening section 19, which at the same time forms the end section 27 of the tool carrier 4, is in turn shaped into a socket wrench 24.
  • the axis 14 with tools 20 to 23 is arranged in its side webs 13, which are only indicated by dashed lines and can be opened by 180 °.
  • the type of motor-operated device 1 is not defined, since each operating part of a starting element can act as a tool carrier.
