Definitions

  • the present invention relates to a tool handle, in particular for precision screwdrivers, of the type comprising a body surmounted by a freely rotating head.
  • Screwdrivers having a tool handle of the aforementioned type have the advantage of decoupling the axial force and the rotational movement thanks to the presence of a freely rotating head.
  • none of the known screwdrivers provides a compromise between comfort and handling precision which is satisfactory in the three sockets mentioned above.
  • the invention aims to fill this gap. To this end, it relates to a tool handle of the aforementioned type, characterized in that the body has an intermediate bulge, and in that the head has an enlarged free end forming a bead whose meridian section has an outline rounded, the height of this head being of the same order as its maximum diameter.
  • the invention also relates to a tool, in particular a precision screwdriver, equipped with a tool handle as defined above.
  • the precision screwdriver shown in the drawings consists of a handle 1 of elongated shape, with a general axis XX assumed to be vertical, at the lower end (considering FIG. 1) of which a screwdriver rod 2 is fixed coaxially.
  • 1 itself consists of a body 3 on the upper end of which is mounted a ring 4 surmounted by a freely rotating head 5.
  • the head 5 of the screwdriver is traversed axially right through by a bore 18 which comprises from bottom to top three parts with increasing diameters: a lower part of the same diameter as the pin 14 and whose height is slightly less than that of this pin up to shoulder 16; an intermediate part of the same diameter as the head 15 of the tenon 14 and whose height is slightly greater than that of this head; and an upper part with a diameter slightly greater than the previous one.
  • the meridian half-section of the head 5 is defined by two arcs of a circle: a concave lower arc 19, of relatively large radius, possibly extended downwards by a short straight line parallel to the axis XX, and an arc of a convex upper circle 20, of considerably smaller radius, which is tangentially connected to the previous one and ends at the upper mouth of the bore 18, a little below the upper extreme plane P of the head 5.
  • the head 5 has an enlarged upper end forming a bead with a rounded outline 20.
  • the height of this head is of the same order as its maximum diameter.
  • the head 5 For mounting the head 5, we put everything on first on the ring holder 13 the ring 4, the outside diameter of which is substantially the same as the minimum diameter of the upper part 12 of the body 3. Then the head 5 is forcibly pushed into the tenon 14, until snap-fastening under the shoulder 16. The head 5 is then freely rotatably mounted on the body 3, with little axial and radial play. Finally, the tool is completed with a pad 21 of the same height as the upper part of the bore 18 and which is force fitted into the latter.
  • the last phalanx of the index finds a stable and comfortable seat on the head 5 with a broad and concave top.
  • the thumb and middle finger can rotate the body 3 at different speeds and with different couples, depending on their position along this body. During this rotation, as the pellet 21 is secured to the head 5, no moving part of the tool is in contact with the index finger.
  • the large and concave head 5 is positioned in a stable and comfortable manner.
  • the bulge 9 provides a well-defined position for wedging the thumb, index and middle fingers, and in this position, during the rotation of the body, the latter never rubs against the first phalanx of the index finger or the major, no moving part is in contact with the index recess, and thanks to the curved contour 20, no edge or quasi-edge comes to injure the hand. This remains true if, to modify the torque or the screwing / unscrewing speed, the user moves the thumb, index and middle finger along the body 3.
  • the little or ring finger can grasp the firm and stable head 5, while being housed in the concave rounding 19. Thanks to this rounding, the screwdriver is well wedged against the palm, without contact between the little finger or the ring finger and the movable body 3.
  • the three driving fingers (thumb, index and middle finger) have at their disposal a net rear setting provided by the bulge 9, while being able to be placed in front of or behind it to adjust the speed and the torque of screwing / unscrewing.
  • the shape of the gougezes 7 offers greater handling comfort than hexagon or vivid groove configurations, without significant loss of movement precision.
  • the full tenon 14-through bore 18 combination makes it possible to obtain both good precision in mounting the head 5, with low clearances which are well controlled, and a high tear resistance of the head 5.
  • the pellet 21 by supplementing the asphalting by the pellet 21, one obtains not only the aforementioned advantage of absence of a rotating part at the top of the tool, but also, in addition to better aesthetics, the possibility of providing this pellet with a tool identification code, for example of a color; this is very convenient when a series of tools is stored on a rack which hides the lower part.
  • the ring 4 can fulfill one or more of the following functions: aesthetics, marking, identification of the tool, friction ring for the rotation of the head 5.
