Definitions

  • the invention relates to an assembly for producing a ready-to use threaded end piece by an end user, comprising a threaded rod and a tool, in which the threaded rod is provided with external screw thread, a threaded rod which is clearly suitable for and intended for such an assembly, as well as a tool which is clearly suitable for and intended for such an assembly.
  • threaded ends are produced by taking pieces from a threaded rod in various known manners or by separating them off by, for example, grinding, cutting by means of a pair of cutting nippers, sawing or another similar technique.
  • the invention provides an assembly according to claim 1.
  • the break-off areas it is possible to produce ready-to-use threaded ends by means of the tool. It is even possible to break the threaded rod in a breaking area by means of nothing more than manual force, although this is not advisable due to the possible risks of injury.
  • the invention furthermore relates to an assembly for producing a ready-to-use threaded end piece by an end user, comprising a threaded rod and a tool, in which the threaded rod is provided with external screw thread and with break-off areas at a regular distance apart, which distances determine a basic threaded end length, and in which the tool comprises an input or a passage through which a part of the threaded rod can be inserted or fed through up to a selected break-off area, and comprises a break-off facility for exerting bending forces on the threaded rod on either side of the selected break-off area for breaking off a threaded end from the threaded rod, which threaded end has a desired number of basic threaded end lengths, preferably on the one hand bending forces acting between the selected break-off area and the subsequent break-off areas and at least one counterforce acting on the selected break-off area.
  • the invention relates to a tool therefor.
  • fig. 1 shows an assembly comprising a threaded rod and tool according to the invention
  • fig. 2a shows a part of a threaded rod according to the invention
  • fig. 2b shows a detail from fig. 2a.
  • Fig. 1 shows an assembly comprising a threaded rod 1 and tool 2 according to the invention, in which the threaded rod 1 is provided with break-off areas 4, which are situated a distance apart and in which the distance apart determines the length of the basic threaded end pieces 3, which form ready-to-use threaded ends after being broken off the threaded rod.
  • break-off areas 4 which are situated a distance apart and in which the distance apart determines the length of the basic threaded end pieces 3, which form ready-to-use threaded ends after being broken off the threaded rod.
  • threaded ends are thus produced which are an integral multiple of the length of a base piece 3.
  • a base piece will have
  • the length of the break-off area will be approximately 3-5 mm. Preferably, this length is approximately around 4 mm.
  • the tool 2 is provided with a slot 7, into which the threaded end can be inserted in a fitting manner, and is provided with a handle 8, which extends substantially radially with respect to the slot 7.
  • the operation is as follows. A user requires a certain length of threaded end. The user then counts the number of base units on the threaded rod which have to be removed from the threaded rod. The user will then insert the threaded rod into the slot 7 of the tool 2 with the end of the tool at the desired break-off surface. Upon moving the handle 8 towards the longitudinal axis of the threaded rod, the threaded rod will break at the breaking element, which is situated closest to the end of the slot 7 of the tool 2. In this case, the end user holds the threaded rod, for example in his hand, with the threaded rod protruding from his hand at the break-off area, where the breakage or fracture is to take place, and will place the tool on the threaded rod above his hand.
  • the threaded rod with two identical tools 2, in which case, for example, the one handle of the tool extends in the one direction and the other handle of the second tool extends in the other direction. Both tools will then be arranged on the threaded rod on either side of the break-off or fracture area, where the break has to be effected. It is also possible to arrange two tool parts or two tools on either side of the break-off area and to move the handles towards one another as a result of which a bending force is exerted on the threaded rod on either side of the break-off area.
  • Fig. 2a shows a threaded rod according to the invention in more detail.
  • the threaded rod comprises basic threaded end pieces, the length of which is denoted by L.
  • An end user or user of a threaded end piece can select the length of the final threaded end he requires by selecting a number of these basic threaded end pieces.
  • Break-off areas 4 are provided on the threaded end 1, at the regular distance apart denoted by the abovementioned L. Along these break-off areas 4, the screw thread has been removed, at least up to the valley, indicated by 10, of the screw thread. Furthermore, the break- off area 4 is divided in two identical parts by weakening 6, in this case a continuous V- shaped groove 6.
  • the weakening in this case has to be such that a break can be achieved with a minimum expenditure of effort, even by hand, but the impact on the (tensile) strength of the threaded rod is reduced to a minimum.
  • the groove may also have a round bottom, be shaped like an hour glass, or have a straight bottom.
  • the weakening is continuous, runs around the rod, preferably a continuous groove.
  • the break-off section 4 is illustrated in more detail in fig. 2b.
  • the peaks 9 and valleys 10 of the screw thread are clearly indicated. It can also clearly be seen in the inset that the screw thread has been removed in the break-off area 4, at least up to the valley 10 of the screw thread. As a result thereof, a nut or another component which is to run along the screw thread is able to pass the break-off area.
  • the weakening results in two areas 5 without screw thread, which are separated by the (in this case) continuous (in this case) V-shaped breaking groove 6 as weakening.
  • a set of threaded rods is provided, in which the length L between the break-off surfaces of the various threaded rods varies.
  • a threaded rod could for example be provided, in which the distance between the break-off surfaces is 2 cm, a threaded rod in which the distance between the break-off areas is 3 cm, and a threaded rod in which this distance between the break-off areas is S cm.
  • the threaded rod is preferably made of metal, such as iron or steel. However, it is also possible to make the threaded rod from a plastic, such as for example nylon.

Abstract

La présente invention concerne un ensemble permettant de produire une pièce à extrémité filetée prête à l'emploi par un utilisateur final, comprenant une tige filetée et un outil. Ladite tige filetée est pourvue d'un filetage de vis externe et de zones de rupture disposées à une distance régulière les unes des autres, ces distances déterminant une longueur d'extrémité filetée de base. Ledit outil comprend un orifice ou un passage à travers lequel une partie de la tige filetée peut être insérée ou introduite jusqu'à une zone de rupture choisie, ainsi qu'un dispositif de rupture destiné à exercer un couple sur une tige filetée de base, une première force du couple étant exercée sur la zone de rupture choisie pour séparer une extrémité filetée de la tige filetée présentant un nombre souhaité de longueurs d'extrémité filetée de base.
