Definitions

  • the invention relates to an assembly tool with a nut turning tool, which is connected via a one-way clutch to a hand lever-like grip part, and hammer-like striking surfaces are formed in the outer region of the mounting of the nut turning tool.
  • Such an assembly tool is known, for example, from DE-U-1 723 997.
  • the fitter When assembling and disassembling a variety of steel structures, especially scaffolding, screws have to be tightened or loosened, wedges have to be tightened or loosened, and other components have to be moved into a fitting position by impact forces.
  • the fitter mostly uses a wrench, usually called an idle clutch, freewheel or ratchet or ratchet, and a hammer. Due to the annoying handling of two tools, the fitters usually use the ratchet wrench to hit instead of a hammer at the same time. For this he has no suitable areas with a correspondingly stable environment. The housing of the freewheel clutch is often damaged and the freewheel function may be impaired.
  • DE-A-26 39 988 shows at one end a hammer head and at the other end a ratchet with a polygonal pin for holding nuts.
  • a tool is difficult to transport and difficult to handle.
  • This known combination tool has a nut turning tool, but no nut plug tube, which would be connected directly to a hand lever-like handle part via a one-way clutch.
  • SU-A-13 08 456 shows a hexagonal tool with a handle and a special head design, which, however, has not been used in practice and, as can be seen from the drawings, is also not specially designed for use as a hammer.
  • DE-U-17 23 997 also shows a ratchet wrench for tubular frame couplings, in which the head part of the ratchet wrench surrounding the plug-in sleeve with the ratchet toothed ring and the associated pawls is provided on the circumference with reinforcements, preferably in the form of hammer-like projections, which also use the ratchet wrench as Allow striking tool.
  • the head part which is firmly connected to the handle and which receives the movable parts, is provided with hammer-like reinforcements on the circumference. It is not specified and also not apparent that the head and handle should be made of different materials. Despite the fact that this proposal has been known for a long time, it has not found its way into practice. This is probably due to the poor choice of materials and inappropriate weight distribution.
  • the invention has for its object to provide an assembly tool for screw heads and nuts with training for tightening and striking wedges by arranging hammer-like approaches such that inexpensive structure design and choice of material with the greatest possible suitability for hitting without injury to the Tooth and pawl arrangement low weight and particularly advantageous weight distribution and inexpensive manufacturing options can be achieved.
  • the elongated handle part is formed with a long handling part and an upper ring and guide part made of light metal and that a freewheel cover part designed as a separately manufactured component is provided with two reinforcing features which are arranged on the outside and opposite one another and have the hammer-like striking surfaces , which also have overlapping the ring and guide part of the handle part, partially nose-like edge shapes and wherein the freewheel cover part is designed as a steel forged part.
  • Ring part of the freewheel cover part has formed the striking surfaces so directly that they grip around the ring part of the light metal grip part projecting beyond the part plane with inner part cylinder surfaces.
  • the ratchet wrench is a tool with a very uneven weight distribution, it is particularly suitable for hammer-like training in the area of the already heavy ratchet and the nut plug-in tube.
  • the high weight of the nut tool or head tool is also used as part of the hammer head for a large weight of the same.
  • the assembly tool according to the invention can advantageously be designed such that it is a ratchet wrench that can be used in both directions of rotation and has a continuous hexagon tube as a nut plug-in tube. Furthermore, it can be provided that the reinforcement features have a width that is approximately the same as the bearing diameter of the nut plug-in tube and that the length of the reinforcement features is about 5: 7 to the width thereof. It is expedient if the inner contour of the reinforcement forms part-cylindrical in the vicinity of the cylindrical outer wall of the ring and guide part.
  • the new assembly tool 10 is designed as a combination tool and has a handle part 11 and a freewheel cover part 12. Both have ring holders for the nut plug-in tube 14 which is designed with an hexagon socket. This has an external toothing 15. The detent pawl which can be displaced in an inclined groove engages in the external toothing 16, which is pressed into the holding position by the spring 17.
  • the handle part 11 has a long handling part 18 and an upper ring and guide part 19. They are designed here as a one-piece light metal molded part, in particular a die-cast part.
  • the nut plug-in tube 14 is held by a freewheel cover part 12 which is customarily designed in its storage area and with regard to the attachment.
  • Both components are equipped with mating surfaces 20, by means of which they lie on one another. Rivets, screws or other connecting means 21 extend through these.
  • the freewheel cover part 12 has two reinforcing features 22 on the outside. These extend laterally over the round ring area of the ring and guide part 19 and are designed there like a nose. You have outer Striking surfaces 24 with a width of 26 and a length of 25. The width 26 is chosen in such a way that the head dimensions allow for the material distribution during manufacture and make the use of a hammer appear expedient. The length 25 is chosen so that the entire thickness of the holding part of the tool, so that the ends of the nut tube 14 protrude in the usual way.
  • the handle part 11 is made of light metal die-casting
  • the freewheel cover part 12 is made of steel as forgings.
  • the design for using a powerful hammer can be easily and advantageously realized without additional components only by changing the shape of the one tool housing part. It is a very useful, very easy to handle and unnecessary fiddling with individual tools, light and highly stable combination tool.
  • the handle part (11) is made of light metal and the freewheel cover part (12) having the reinforcing features (22) with the striking surfaces (24) is a steel forged part.
