Definitions

  • the invention relates to a ratchet with a working head articulated on the handle and with a securing device for the selected handle bend while working with the ratchet.
  • Ratchets are widely used as screwdriving tools and are mainly offered in conjunction with socket wrench sets in which a large number of interchangeable socket wrench heads are assigned to the square head of the ratchet.
  • the working heads are rigidly connected to the handle of the ratchet.
  • the invention has for its object to improve the generic ratchet in such a way that there is reliable protection against slipping and the associated risk of hand injuries.
  • the securing device consists of an axially adjustable, axially manually adjustable pin-shaped bolt and consists of at least one deep locking opening arranged on the other ratchet part with two parallel locking walls enclosing the bolt on the side and that the bolt is assigned a separate, manually operated adjusting member.
  • the invention now provides an almost rigid connection between the working head and the handle, in which an unwanted change in the angle between the working head and the handle is no longer possible, but such a change can only be made by deliberately actuating a separate adjusting member.
  • the ratchet according to the invention can be used without the risk of the ratchet handle slipping or knocking out, even in those cases where the greatest force has to be exerted on the ratchet handle.
  • the invention can be implemented constructively in various ways.
  • the bolt protrudes axially from the fork base and against the force of a spring accommodated in the handle handle by means of a slide guided in a slot of the handle handle can be retracted behind the fork base.
  • the slider and its associated receiving slot penetrate the grip part diametrically and that the slider is provided with gripping surfaces at two diametrically opposite ends, so that the slider between the thumb and index finger of one hand can be gripped at the same time.
  • the extension of the working head is in any case provided with a blind hole in its longitudinal axis for rigid locking of the ratchet in the extended position.
  • This makes it possible to work with the straight ratchet as with a rigid ratchet, but at the same time there is still the possibility to bend the working head after lifting the lock and to place the locking pin on, for example, toothed grooves of the extension piece - analogous to the locking ball so far - and to work with an angled ratchet.
  • the extension piece is provided with a ring of deep locking openings, so that all angled ratchet positions are reliably secured against slipping or knocking out of the ratchet handle.
  • the invention can also provide that a locking pin which can be advanced from the end of the handle against the force of a return spring is arranged in the handle, which in the advanced locking position is seated on counterstops of the handle, and can also be removed from the counterstops by hand Stop piece is held.
  • This adjustment arrangement for the locking pen corresponds to the adjustment of the pen common with ballpoint pens.
  • the ratchet shown in FIGS. 1 to 4 consists of a handle handle 1 with a handle 2, a working head 3 with a square piece 4 mounted as a ratchet, which are pivoted to one another via an articulated axis 5.
  • the handle 1 is designed at one end as a bearing fork 6, which has a hole for the hinge axis 5 provided attachment 7 of the working head 3.
  • a pin-shaped bolt 8 projects axially, see also FIG. 3, which can be retracted against the force of a return spring 9 accommodated in the handle 1 by means of a slide 10.
  • the slider 10 is guided in a slot 11 of the handle 1 and provided at its outer, widened end with a roughened grip surface 12 so that the bolt 8 can be withdrawn, for example, with a thumb pressed onto the grip surface 12.
  • the working head 3 is provided in the center on the side of its attachment 7 facing away from it with a locking blind hole 13 which is intended for receiving the locking pin 8 when the working head 3 and handle handle 1 are in a straight orientation.
  • the ratchet is rigidly locked in the extended position. After pulling back the bolt 8, the ratchet can be angled approximately in the manner shown in FIG. 1, and after releasing the slide 12, the bolt 8 then sits with its head in one of the tooth gaps 14, 15, 16, which is laterally next to the Locking hole 13 are provided on the attachment 7.
  • the extension piece 1 7 of the working head is provided with a ring of locking openings 18, 19, 20, 21, which are each suitably dimensioned for receiving the pin-shaped bolt 8 and each have two parallel boundary walls 22, 23 for a rotationally secure border of the bolt 8.
  • a groove-shaped locking opening 19 could also be provided instead of a cylindrical locking hole 13 as in the exemplary embodiment according to FIG. 5.
  • a slide 24 which penetrates the handle 1 diametrically and an associated guide slot 25 are provided.
  • the slide 24 is provided on its two diametrically opposite outer sides each with roughened grip surfaces 26, 27 which are gripped between the thumb and index finger of one hand. Because of the risk of canting avoided in the exemplary embodiment according to FIG. 6, the slide 24 can be withdrawn particularly smoothly.
  • the locking device is constructed in a kinematic reversal to the previously described exemplary embodiments.
  • the end faces of the two front ones Fork ends 28, 29 of the handle 1 each provided with a ring of locking holes 30, 31, 32 and a pin-shaped bolt 34, 35 with slide 36 and 37 and return spring 38, 39 are arranged in the opposite corner regions of the working head 33.
  • the working head is designed as in FIG. 5.
  • the handle 40 is here provided with a continuous axial bore 41 in which a long locking pin 42 is axially displaceably mounted.
  • the locking pin 42 is enclosed by a compression spring 43, which is clamped between a rear stop shoulder 44 of the locking pin 42 and a front, inner shoulder 45 on the handle side and thus loads the locking pin in the direction of being drawn into the handle part.
  • the locking pin is seated at its rear end on a stop piece 46 which, in the position shown, rests on counter stops 47 distributed over the circumference of the housing.
  • the stop piece 46 By pressing a plunger member 48 protruding from the rear of the handle, the stop piece 46 can be lifted off from the counter stops 47, after which it is pushed back up past the counter stops 47 under the influence of the spring 43 until the locking mechanism pin 42 is disengaged from the working head. By pressing the plunger 48 again, the stop piece 46 can be placed on the counter stops 47 again.
  • the stop piece 46 and the counter stops 47 are designed as is customary in ballpoint pens and are therefore no longer illustrated in detail here.
  • Fig. 10 shows the preferred embodiment of the ratchet, in which the extension 7 projecting at right angles with respect to the plug-on direction of the square piece 4 at its free end lying laterally next to the square piece 4 with locking holes 49 arranged on a circular arc for the articulated fork 6 of the handle part 1 stored bolt 8 are arranged.
  • the holes 49 designed as blind bores are directed radially onto the hinge axis 5.
  • the bolt 8 seated on the slide 24 is easily retractable with the hand holding the ratchet, that is to say with only one-hand actuation, since the diametrically opposed grip surfaces 26, 27 can be gripped between the thumb and index finger.
