Definitions

  • the invention relates to a handle for a hand tool, especially screwdriver handle, according to Preamble of claim 1 as e.g. for various Screwing work is used.
  • screwdriver handles one end face e.g. via a clamping sleeve, different Tool inserts or tool shanks with various active parts, e.g. Support screwdriver, Phillips screwdriver, Hexagon / Allen key is interchangeably attachable.
  • These handles are in connection with known Tool boxes, especially ratchet boxes, the various Contains nuts and bits, cannot be used. moreover can only be used in their classic form as Screwdriver can be used, so for less effort Screwdriving work while for larger torques to a T-handle or in space-limited situations a revolver grip must be avoided. So there are three each for three different work situations to provide different tools.
  • DE-C-36 36 025 is a screwdriver handle known in which a tool accessory, such as an Allen key, Can be attached to the handle in two different settings is in a longitudinal axial position and one too this vertical, central position, which creates a T-handle results.
  • a tool accessory such as an Allen key
  • the tool insert has a head part that is in a corresponding Slit of the handle in different positions is insertable.
  • a normal screwdriver function and a T screwdriver function can be achieved it is also not for other commercially available tool inserts usable as only tool inserts with the special designed for this handle can be used.
  • US-A-3,850,056 shows a screwing tool whose handle body also has an axial bore and has an axial-radial slot into the known, commercially available L-shaped screwing tools, generally under Allen screwdriver known, with the help of on the long legs of the L screwdriver, inserted sleeve becomes.
  • the two leg ends of the L tool protrude axially or radially out of the handle body, so that a combination tool is provided that both as a normal screwdriver and as a T-handle screwdriver can be used.
  • this is known tool only in combination of the empty Handle body can be used with sleeves and L-shaped tools.
  • Commercial tools or inserts, nuts, bits, ratchets etc. cannot be used in combination with this tool or the Handle body of this tool can be used, which its applicability is very limited.
  • the object of the invention is a handle o.g. genus specify that it can be divided into at least two different screwing work positions, at least as a screwdriver and as a T-handle screwdriver use, in quick combination, with commercially available Tools or inserts, nuts, bits, ratchets etc. and which also has the simplest possible structure.
  • the handle of the invention has precautions to attach the various tool inserts to his Handle body at least two polygonal mounting pins, to the well-known tool inserts via their receiving sleeves can be attached attachable.
  • a simple screwdriver as a T and Revolver grip usable multi-grip according to the invention can be used for different torques can be used as required. Also can be done directly or via a small one Adapter plug part a ratchet element, e.g. a freewheel ratchet nut according to DE-U-297 23 472, are used, wherein then the tool inserts to this ratchet if necessary are contagious. So the handle can be in all three Use positions as ratchet handle in connection with a wide variety of tool inserts.
  • the handle can be used together with the corresponding accessories can be assembled into a set, e.g. in one corresponding toolbox that next to the screwdriver handle at least one ratchet element, various Extensions, nuts, bits, etc. may contain.
  • cones are each known Have polygonal profile, such as square or Hexagonal profile with the corresponding square or Hexagon internal profiles of the socket sleeves of the tool inserts or corresponding extensions or adapter parts, interact. It goes without saying that at Arrangement of square mounting pins in a corresponding Tool set at least one square / hex adapter part is provided to tool inserts with the same handle optimal with different receiving sleeves to be able to use.
  • the pins on the handle body can more or less sunk or arranged outstanding. So you can protrude completely from the outer surface of the handle, whereby the each free-standing tenon length is only slightly larger than the depth of the profile socket of the sleeve of the tool inserts should be.
  • the pins can also be fully or partially under control be sunk, one around each of the pins in the body coaxial, cylindrical recess for inserting the Tool holder sleeves are provided. It is special advantageous and inexpensive to handle if all three pins are completely sunk in the handle or at least the both opening into the outer surface of the handle or projecting pins for the T and turret positions. So is particularly classic in the use of the handle Screwdriver handle when turning the handle around its axis, the hand does not stick to the protruding one Hang the pin so that injuries are avoided.
  • the axial pin can also be easily from the Area be partially or completely protruding, since this pin does not move any further when handling the handle is disturbing.
  • the handle can be made in one piece be in the handle body or the pins arranged or arranged and are e.g. right at the manufacturing stage of the handle body with cast or subsequently worked out.
  • the handle body can also be made of plastic, hard rubber, Cast aluminum or other form, injection, casting or sinterable material, the pins made of Steel or cast material made and in the handle material are embedded in a rotationally fixed manner.
  • each a polygon pin end and an anchoring end have, the anchoring end a flat broad-cut or axially dovetailed or cut open and pressed apart form having.
  • the flat broad end or the spread apart Dovetail end finds a good turning and non-slip anchoring of the pin in the body material instead of.
  • each with two pins on one curved, commercially available profile rod provided are, while the third pin on a second profile bar is provided on the first, curved Profile rod is attached by gluing, welding or the like.
  • Profile rod can be provided, the T-pin and the Revolver pin has, while the axially pointing Screwdriver tenon is a single use. So are the more torque-loaded pins, i.e. the T and the turret is optimally anchored in the body, while the less resilient single use in the Screwdriver position is provided, which is a lesser Torque must absorb.
  • the Grip pins each in a manner known per se, locking devices, like spring-loaded ball or radial pin embedded with the corresponding recesses in the Work tool insert sleeves together.
  • the inventive Handle 1 from an elongated handle body 2, on the three receiving pins 3, 4, 5 are arranged.
  • the pins 3, 4, 5 designed as a hexagon pin, which from the outer surfaces of the handle body in different positions to each other and to the handle body. So is the an end face 6 of the handle body 2, coaxial to the longitudinal axis of the body 7, the screwdriver pin 3 arranged while essentially centered to body length and at the same time perpendicular to the body surface as well as the Longitudinal axis 7, the T-pin 4 is arranged.
  • the Revolver pin 5 in the front zone 8 so on the opposite Arranged end to end face 6 and essentially in the same plane with the other two pins 3 and 4, but at an angle of 120 ° to Screwdriver pin 3.
  • the three pins 3, 4, 5 are designed as square pins, which are at least partially embedded in the handle.
  • the pins 3, 4, 5 each with one to the pin concentric, cylindrical recess 9 surround the its depth depends on how far the spigot is sunk in the handle body, i.e. how far the Face of the pin over the corresponding body surface stands out or reset in relation to this is arranged. So here the pin 3 is only half sunk, while the pins 4 and 5 are completely sunk, even slightly deeper than the body surface area, um Injuries, especially when handling the handle as a screwdriver handle to avoid. It is also too recognize that in the embodiment of FIGS. 2 and 3 the turret pin 5 at an angle of 90 ° to the longitudinal axis of the handle is arranged near the end face 8.
  • FIGS. 4 to 6 are the pins 3, 4 arranged in the handle body 2, 5 each in the same angular position (0 °, 90 °, 120 °) Handle longitudinal axis 7 arranged. They each have one Locking device 17 on, in a manner known per se e.g. from a radially recessed, spring-loaded ball consists. All three pins 3, 4, 5 are completely sunk provided and of equal depth, concentric Surround recesses 9. The pins 3, 4, 5 are on one Polygonal insert provided from a long, just to one end bent at a 120 ° angle profile bar 19 Exists, except for the short, bent part the entire length arranged coaxially to the central axis 7 of the handle is. A short profile bar 20, on the one hand has the T-pin 4 is with its other side the long profile bar 19 is essentially welded in the middle, that the three pins 3, 4, 5 in the same center plane of the handle body.
  • a two-peg insert 21 is provided, which consists of a U-shaped bar 22, on its two short 90 ° or 120 ° T legs the pins 4 and 5 are provided. It is also a single assignment 23 coaxially on the front 6 of the handle used the pin 3 and at the other end a flat or broad-cut one Anchoring end 24 has.
  • a short profile bar e.g. a square profile rod piece be used on his one End to the anchoring end 24 one-sided or symmetrical is compressed or beaten on two sides, so that a blade-shaped anchoring part is created.
  • the other End is provided with a locking device 17 and protrudes into the concentric recess 9, here in essentially flush with the end face 6. It it can be seen that the insert 21 via its pins 4, 5 can take on a greater torque than that Single use 23, however, the torque is not so high need to take over, since he only the screwdriver pin 3 wears.
  • FIG. 6 it can be seen from Fig. 6, as in another Version in handle body 2 three individual inserts 25 provided are of a similar structure as the individual insert 23 from FIG. 5 is only different the formation of the anchoring end, which here as dovetail-shaped anchoring end 26 is formed is.
