Definitions

  • the invention is based on an additional handle of the type according to the preamble of claim 1.
  • Known additional handles of this type are constructed with a large number of individual parts and are therefore expensive to manufacture. Functionally, they have the disadvantage that they can only be pushed onto the spindle neck of the drilling machine in different rotational positions and this rotational position can only be corrected by pulling them off and pushing them back on again. This cumbersome handling takes a lot of time. The operator therefore often refrains from looking for the cheapest, most comfortable rotary position for the additional handle. This in turn leads to faster fatigue and can even be harmful to your health.
  • the additional handle according to the invention with the characterizing features of claim 1, in contrast, has the advantage of being easy to manufacture and of being able to be brought into the optimum rotational position relative to the hand drill.
  • a clamping ring By assigning a clamping ring to a spindle neck with longitudinal notches and an annular groove, which has an additional resilient tongue with a detent fitting into the longitudinal notches, the additional handle, once pushed on, can be rotated from longitudinal notch to longitudinal notch until the correct rotary position is found.
  • the latch spring resiliently without great resistance from a not yet suitable longitudinal notch and noticeably in the next.
  • the latch Due to the stop attached to the resilient part of the clamping ring and behind the latch back of the tongue, the latch can be blocked in the rotational position found within the selected longitudinal notch, simply by tightening the clamping ring. With the same spring stroke of the resilient part of the clamping ring, the rib can also engage in the annular groove on the spindle neck. The additional handle is positively secured against rotation as well as against longitudinal displacement by the clamping movement on the clamping ring.
  • FIG. 1 shows a partial view of an additional handle with the complete clamping ring
  • FIG. 2 shows a detail at A in FIG. 1, with the additional handle fixed
  • FIG. 3 shows a side view of a spindle neck of a corresponding hand drill
  • FIG. 4 shows a side view of FIG. 3.
  • An additional handle 2 can be attached to a spindle neck 1 of a hand drill.
  • This spindle neck 1 has longitudinal notches 3 and an annular groove 4.
  • a clamping ring 5 of the additional handle 2 is used for fastening.
  • This has a resilient part 6 and an additional resilient tongue 7 with a locking lug 8.
  • a stop 9 is attached to the resilient part 6. The stop surface of this stop 9 is behind the back of the locking lug 8, at a distance which corresponds approximately to the spring travel of the resilient part 6. This distance arises when the locking lug 8 engages in a longitudinal notch 3, but the clamping ring 5 has not yet been tightened.
  • Both projections 10 and 11 are connected at their outer end via an eyelet 13. Between the locking lug 8 and the projection 11, the resilient part 6 of the clamping ring 5 has a rib 14. This rib 14 is arranged such that it lies outside the spindle neck 1 when the clamping ring 5 is not tensioned, but when tightening it into the annular groove 4 of the spindle neck 1 can intervene.
  • the projection 10 has a guide 15 for a hexagonal rod 16. This guide 15 is open towards the slot 12 and also towards a subsequent recess 17. A resilient tongue 18 is formed in the recess 17, the resilient end of which rests against the surface of the hexagonal rod 16 facing it.
  • the surface of the hexagonal bar 16 facing the slot 12 is provided with teeth 19.
  • Matching teeth 20 on the projection 11 are juxtaposed with the teeth 19.
  • a clamping bolt 23 is inserted through mutually aligned bores 21 and 22 in the projections 10 and 11.
  • One end 24 of this clamping bolt 23 protrudes into a recess 25 behind the projection 10.
  • a washer 26 and a locking washer 27 the clamping bolt is supported on the rear surface of the projection 10.
  • the other end of the clamping bolt 23 protrudes from the rear of the projection 11 and there carries a rotary knob 28 with an axially acting cam track 29.
  • the cam track 29 is opposed to a ring 30 on the projection 11 with a corresponding cam track 31.
  • the clamping bolt 23 is secured in the same way as at the other end by means of a washer 26 and a locking washer 27.
  • the total stroke of the curved tracks 29 and 31 is distributed over an angle of rotation of the rotary knob 28 of approximately 130 ° . It corresponds to the required clamping stroke for tightening the clamping ring 5.
  • the clamping ring 5 is made in one piece with the actual handle 32 of the additional handle 2 from flexible plastic.
  • the state shown in FIG. 1 shows a released clamping ring 5 pushed onto the spindle neck 1 Latch 8 engages in the longitudinal notch 3 under the action of the tongue 7's own spring.
  • the additional handle 2 is still rotatable on the spindle neck 1 from rest to rest. It can also be moved axially.
  • the rotary knob 28 As soon as the rotary knob 28 is turned, its cam track 29 urges the resilient part 6 of the clamping ring 5 into the clamping position.
  • the rib 14 engages in the ring groove 4 and thus secures against axial displacement of the additional handle 2.
  • the stop 9 lies against the back of the locking lug 8 and blocks it in its locking position.
  • the additional handle is also secured against rotation on the spindle neck 1 (FIG. 2).
  • the teeth 19 and 20 interlock so that the hexagonal rod 16 serving as a depth stop is also fixed.
  • the rotary knob 28 is turned back.
  • the slot 12 opens, the rib 14 emerges from the annular groove 4 and the stop 9 from the back of the locking lug 8.
  • the tooth mesh between 19 and 20 is released.
  • the hexagonal rod 16 can be shifted in its guidance and the additional handle 2 can be shifted and / or rotated on the spindle neck 1.
  • a new rotational position or a different stop depth can thus be set or the additional handle 2 can be removed from the spindle neck 1.
  • Optimal use of the additional handle 2 is thus ensured with the least possible expenditure on parts and assembly time.
