Definitions

• the invention relates to a handle for a hand tool, in particular screwdriver handle, according to the preamble of claim 1, as e.g. used for various screwdriving jobs.
• screwdriver handles on one end face of which 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 can be attached interchangeably.
• These handles cannot be used in conjunction with tool boxes known per se, in particular ratchet boxes which contain different nuts and bits.
• they can only be used in their classic form as screwdrivers, ie for less forceful screwing work, while for larger torques a T-handle or, in space-limited situations, a revolver grip must be avoided. Three different tools must therefore be provided for three different work situations.
• a screwdriver handle is known in which a tool accessory, such as Allen key, can be fastened to the handle part in two different settings, namely in a longitudinally axial position and in a central position perpendicular to this, resulting in a T-handle.
• the tool insert has a head part which can be pushed and inserted in different positions in a corresponding slot in the handle.
• a normal screwdriver function and a T-screwdriver function can be achieved with this known handle, it is also not usable for other commercially available tool inserts, since only tool inserts with the special head designed for this handle can be used.
• the object of the invention is a handle o.g. Specify a genus that makes it possible to use it in three different screwing work positions, i.e. as a screwdriver, T-handle, revolver handle, in a quick combination, with commercially available tools or inserts, nuts, bits, ratchets, etc., and also one - Has the best possible structure.
• the handle of the invention has provisions for attaching the various tool inserts to it Handle body on at least two polygonal mounting pins on which the known tool inserts can be attached by means of their mounting sleeves.
• a first pin is outstandingly arranged coaxially in the longitudinal direction on an end face of the tool body, while at least one further pin, which is oriented at an angle to the first pin and is spaced apart from it, is provided.
• a second pin being arranged perpendicular to the longitudinal axis and thus to the first pin and at the same time centrally to the longitudinal extension of the handle, in addition to the first, axially projecting pin.
• a third pin is arranged in the zone of the end face of the handle opposite the first pin, specifically at an angle of 90 to 120 ° to the orientation of the first pin or to the longitudinal axis of the handle, whereby a revolver handle can be provided.
• the 120 ° position, in which the pin essentially opens at the front edge is particularly advantageous, as a result of which an oblique turret grip with particularly good functioning is present.
• the multi-handle according to the invention which can thus be used as a simple screwdriver, as a T-grip and as a revolver grip, can be used as required due to the different possible uses for different torques.
• a ratchet element for example a freewheel ratchet nut according to DE 297 23 472 UI, can also be used directly or via a small adapter plug part, in which case the tool inserts can then be plugged onto this ratchet as required.
• the handle can be used in all three positions as a ratchet handle in connection with a wide variety of tool inserts.
• the handle can thus be put together with corresponding accessories to form a set, for example in a corresponding tool box, which in addition to the screwdriver handle can contain at least one ratchet element, various extensions, nuts, bits, etc.
• the pins each have a polygonal profile known per se, such as a square or hexagonal profile, which interact with the corresponding square or hexagonal inner profiles of the receiving sleeves of the tool inserts or corresponding extensions or adapter parts. It is understood that, in arrangement of square drive pin in a respective tool set "adapter part hexagon is provided at least one square /, to optimally use with the same handle tool inserts with different receiving sleeves.
• the pins on the handle body can be more or less recessed or arranged in an outstanding manner. This means that they can protrude completely from the outer surface of the handle, whereby the free-standing pin length should only be slightly greater than the depth of the profile receptacle of the socket of the tool inserts.
• the pins can also be completely or partially recessed in the handle, a coaxial, cylindrical recess being provided around the pins in the body for inserting the tool holder sleeves. It is particularly advantageous and inexpensive to handle if all three pins are completely sunk in the handle or at least the two pins opening or projecting into the outer surface of the handle for the T and turret positions. So especially when using the handle as a classic screwdriver handle, when turning the handle around its axis, the hand does not hang onto the protruding pin, so that injuries are avoided.
• the axial spigot can also be arranged partially or completely protruding from the surface, since this spigot does not interfere with the handling of the handle.
• the handle can be made in one piece overall, that is to say the pins are arranged or arranged in or on the handle body and are cast, for example, at the same time as the handle body is manufactured or subsequently worked out.
• the handle body can also be made of plastic, hard rubber, cast aluminum or other form, injection, pourable or sinterable material, the pins being made of steel or cast material and embedded in the handle material in a rotationally fixed manner.
• pins produced from commercially available polygonal profiles such as square or hexagonal profiles, are embedded in the handle body in the form of polygonal inserts having at least two pins and / or as individual polygonal inserts.
• three individual peg inserts can be provided, each having a polygonal peg end and an anchoring end, the anchoring end having a flat, broad-cut or axially dovetail-shaped or cut open and pressed apart shape.
• the flat, wide end or the spread-apart dovetail end ensures that the pin is firmly anchored in the body material so that it cannot rotate and slide.
• a single, one-piece pin insert with three pins, two pins being provided on a correspondingly curved, commercially available profile bar in the steel profile version, while the third pin is provided on a second profile bar which is attached to the first, bent profile rod is fixed by gluing, welding or the like.
• the long part ie the profile rod carrying the axial pin and the 90 ° or 120 "pin located at the opposite end
• the central T-pin is a short rod that is welded to the long rod
• a transverse groove can be worked into the long profile rod at the level of the T-spigot, into which the inner end of the short profile rod engages in a form-fitting manner and creates a welded connection from the rear by spot welding
• a shorter profile rod bent at both ends, can be provided, which has the T-pin and the turret pin, while the axially pointing screwdriver pin is a single insert.
• the more torque-loaded pins i.e. the T and turret pins, are anchored in the body in a load-bearing manner, while the less resilient single insert is provided in the screwdriver position, which has to absorb less torque.
• locking devices such as spring-loaded balls or bolts, which cooperate with corresponding recesses in the tool insert sleeves, are radially let into the handle pins in a manner known per se.
• FIG. 1 a perspective view of a handle according to the invention in the first embodiment, with hexagon pins projecting completely from the handle body,
• FIG. 2 a perspective view as in FIG. 1, on a handle in the second embodiment, with square pins embedded in the handle body,
• FIG. 3 a top view of the handle from FIG. 2, with insert tools indicated in the insert position
• FIG. 4 a section IV-IV in FIG. 2, an embodiment with a one-piece, welded profiled insert with three pins
• Fig. 5 a section as in Fig. 4, through an embodiment with a short profile insert with two pins for the T and the turret position and a single insert pin for the axial screwdriver position
• Fig. 5 a section as in Fig. 4
• a short profile insert with two pins for the T and the turret position and a single insert pin for the axial screwdriver position
• Fig. 6 a section as in Fig. 4 through an embodiment with three individual pin inserts.
• the handle 1 consists of an elongated handle body 2, on which three receiving pins 3, 4, 5 are arranged.
• the pins 3, 4, 5 are designed as hexagonal pins which protrude from the outer surfaces of the handle body in different positions relative to one another and to the handle body.
• the screwdriver pin 3 is arranged on one end face 6 of the grip body 2, coaxially to the longitudinal axis 7 of the body, while the T-pin 4 is arranged essentially centrally to the length of the body and at the same time perpendicular to the lateral surface of the body and the longitudinal axis 7.
• the turret pin 5 is arranged in the end zone 8, that is to say at the opposite end to the end face 6, and essentially in the same plane as the other two pins 3 and 4, but at an angle of 120 ° to the screwdriver pin 3.
• Figs. 2 and 3 are the three pins 3, 4, 5 formed as square pins, which are at least partially embedded in the handle.
• the pins 3, 4, 5 are each surrounded by a cylindrical recess 9 which is concentric with the pins and whose depth depends on how far the pin is countersunk in the handle body, that is, how far the end face of the pin is over the corresponding one Body surface protrudes or is set back in relation to this. So the pin 3 is only half recessed, while the pins 4 and 5 are completely recessed, even slightly lower than the body surface to avoid injuries, especially when handling the handle as a screwdriver handle. It can also be seen that in the exemplary embodiment according to FIGS. 2 and 3, the turret pin 5 is arranged at an angle of 90 ° to the longitudinal axis of the handle, near the end face 8.
• tool inserts 10, 11, 12 are also at least indicated in the coaxial direction of use for the respective spigot and it can be seen that this each has a receiving sleeve 13 which has an inner profile corresponding to the respective spigot profile, the sleeves Profile depth 14 and the pin profile height 15 are approximately the same.
• the ratchet element 11 to be placed on the pin 4 via its sleeve 13 in FIG. 3 also has a receiving pin 16 on the opposite end face, to which, for example, tool inserts 10, 12 can be fastened, so that a T-ratchet screwdriver provided.
• the pins 3, 4, 5 arranged in the handle body 2 are each arranged in the same angular position (0 °, 90 °, 120 °) to the longitudinal axis 7 of the handle. They each have a locking device 17, which consists, for example, of a radially recessed, spring-loaded ball in a manner known per se. All three pins 3, 4, 5 are provided completely recessed and surrounded by the same depth, concentric recesses 9.
• the pins 3, 4, 5 are provided on a polygonal insert, which consists of a long, only at one end at a 120 "angle bent profile rod 19 which is coaxial to almost the entire length except for the bent, short part
• the central axis 7 of the handle is aligned, and a short profile bar 20, which on the one hand has the T-pin 4, is welded with its other side to the long profile bar 19 so that the three pins 3, 4, 5 are in the same center plane of the handle body.
• a two-pin insert 21 is provided, which consists of a U-shaped bar 22, on the two short 90 ° or 120 ° T legs of which pins 4 and 5 are provided.
• a single insert 23 is inserted coaxially on the end face 6 of the handle, which has the pin 3 at one end and a flat or wide-anchored anchoring end 24 at its other end.
• a short profile bar for example a square profile bar piece, can be used to manufacture this single insert End to the anchoring end 24 is compressed or beaten on one side or symmetrically on both sides, so that a shovel-shaped anchoring part is formed.
• the other end is provided with a locking device 17 and projects into the concentric recess 9, here essentially flush with the end face 6. It can be seen that the insert 21 can take on a greater torque via its pins 4, 5 than the single insert 23, which, however, does not have to take on such a high torque, since it only carries the screwdriver pin 3.
• FIG. 6 it can be seen how in a further embodiment three individual inserts 25 are provided in the handle body 2, which have a similar construction to the single insert 23 from FIG. 5.
• the anchoring end is designed here as a dovetail-shaped anchoring end 26.
• the anchoring end 26 has two arms pointing apart.
• three or more arms can also be provided, so that the anchoring end then has a plurality of anchoring prongs or looks star-shaped.
• These serrations can lie in the same plane, but can also be bent diagonally opposite, for example by cross-cutting.
• the anchoring part can have grooves which are turned in at least on one side and prevent the insert from being torn out unintentionally. LIST OF REFERENCE NUMBERS
