Definitions

  • the present invention relates to a key arrangement and in particular to a key arrangement of a kind which is intended to turn a component forming part of a screwed joint as stated in the preamble of claim 1.
  • a key arrangement designed to turn a component forming part of a screwed joint designated as an impact key
  • said key arrangement being intended to be capable of releasing and to a certain extent also of tightening the screwed joint, for which purpose it exhibits a main shaft, the end of which is provided with a screw-driven blade actuated by a so-called striking arm. Its function derives from the striking arm being caused to move in the desired direction of force, when its kinetic energy will be absorbed by end stops, so that the torque will be transmitted in the form of short but intensive torque pulses which is used to release or to tighten one part of the screwed joint.
  • the present invention relates to a key arrangement of the kind mentioned above and shall exhibit the features stated in the characterizing part of claim 1.
  • the key arrangement consists of a small number of component parts which are able easily to interact with each other so that they may be caused to interact with each other in order to influence the component parts of the screwed joint, but where said components are capable, when not in use, of being combined together into a compact unit for storage.
  • Figure 1 thus shows a perspective view of a key arrangement 1 designed to turn a component forming part of a screwed joint.
  • the component part of the screwed joint is not shown in Figure 1, although said component part is intended to interact with a sleeve 2, a pin or a similar organ.
  • the key arrangement also exhibits a rod-shaped organ 3 capable of interacting with the sleeve 2, a striking arm 4 capable of rotating in conjunction with the organ 3 and a handle 5 designed for a hand holding the key arrangement 1.
  • the striking arm 4 consists of a main part 4a together with mass concentrations 4b executed at one end, or preferably at both ends in accordance with the embodiment shown in Figure 1.
  • the main part 4a is attached by means of a hole 4c to the rod-shaped organ 3 in such a way as to be free to rotate so that the striking arm 4 can be turned between a number of stop positions so that, by coming to a halt in a particular stop position, it is able to transfer kinetic energy associated with the turning motion as shock torque to the rod-shaped organ 3 and to the component 2.
  • At least one stop position is executed as a support 6 arranged adjacent to the striking arm, securely connected to the rod-shaped organ 3 and able to absorb impact forces from the striking arm 4.
  • the centre line 3a of the rod-shaped organ 3 must also be arranged on or adjacent to a centre line 5a of the handle.
  • the handle 5 and the rod-shaped organ 3 be connected together by the expedient of one of them exhibiting a pin 5b and the other exhibiting a recess 3b corresponding to the pin.
  • a part 6a formed between the handle 5 and the organ 3 shall also be so arranged as to serve as a bearing area for the striking arm 4 during its turning motion.
  • the present invention proposes that the support 6 be executed from legs 6' formed on a 'U'-shaped component 6.
  • the component 6 is attached to the rod-shaped organ 3 in such a way as to be free to rotate via a welded joint not shown in the Figure.
  • Figure 1 shows the handle 5 to have been executed with a pin 5b, whereas the rod-shaped organ 3 is shown to have been executed with a recess 3b, whereby the handle 5 and the rod-shaped organ can be brought into interaction with each other and whereby the pin 5b serves as a bearing surface for the arm 4. It may be appropriate to provide a locking arrangement not shown in the Figure in order to lock the handle 5 in its engaged position with the rod-shaped organ 3.
  • Figure 2 illustrates the manner in which a handle 5 has been formed with an internal recess 5c and in which the rod-shaped organ 3 has been formed with a pin 3b', said pin being intended to interact with the recess 5c. In this case, too, it may be appropriate to provide a locking arrangement not shown in detail in the Figure between the pin 3b' and the recess 5c.
  • Figure 2 also shows the manner in which the arm 4 is supported on the pin 3b' so as to be free to rotate and the manner in which the organ 6 has been executed with two legs 6'.
  • the handle 5 be so arranged that it is free to rotate in relation to the rod-shaped organ 3 and the striking arm 4, thereby enabling the striking arm 4 and the organ 3 to rotate without corresponding rotation of the handle 5.
  • the rod-shaped organ 3 may also be executed with a part 3' to which or about which the handle 5 is so arranged that it is free to rotate.
  • Figure 1 shows the rod-shaped organ 3 to have been executed with a tubular part 3' into which a bar 5b which is securely attached to the handle 5 may be introduced.
  • the sleeve 2 or, in the event of the sleeve 2 having been replaced by a pin or similar, the latter may be attached in a previously disclosed manner to the rod-shaped organ in such a way that it is capable of being removed.
  • Figure 2 shows more usual dimensioning of the support 6 in relation to the width of the arm 4, from which it will be appreciated that the distance between the legs 6' should exceed the width of the arm 4 by a factor of between 1.5 and 4.0, although the most practical value is of the order of 3.0.
  • the present invention proposes that the length of the rod-shaped unit 3 together with the sleeve 2 and the support 6 be so dimensioned as to be less than the distance between the opposing surfaces of the mass concentrations 4b, and that the handle 5 and any bar 5b which may be attached to it be similarly dimensioned so as to be capable of being stored directly adjacent to the striking arm 4 between opposing end parts of the mass concentrations 4b.
  • This will produce the advantage that the support 6 will lie next to one of the mass concentrations 4b whilst the sleeve 2 will lie next to the other mass concentration 4b.
