Definitions

  • the present invention relates to a system of binding or assembling by means of a double-threaded bolt.
  • This bolt is coupled to a respective nut which incorporates concentric male and female threads.
  • This nut which makes installation of the dual threaded bolt easier, acts as a threaded insert once installed, facilitating final operation of said bolt.
  • a double-threaded bolt is a bolt where the head has been replaced by a threaded stud having a different thread pitch to the body of the bolt. So, in this bolt's function; screwing in a first direction, the parts of the union are drawn together, whereas if screwing in the opposite direction, the parts are forced apart. The displacement we get per turn is the result of the difference between the two corresponding pitches. It is therefore applicable to any bolted union in which we want either closing and opening, or to maintain a defined distance between the parts.
  • double-threaded bolts is also particularly appropriate to prevent fatigue cracks in pieces where conventional bolt's heads would place concentrated clamping forces on the clamped element's bolt head clamping face. So in pieces where the reduction in weight or volume, is taken to the limit, their use can be very convenient.
  • These bolts can be mounted to join two pieces or even in one piece, giving control of the degree of closure or opening of a slot, acting as a clamp.
  • the difficulty of mounting lies in that the final position of the bolt must be appropriate: as the bolt is varying its position while screwed, so the installation will have to be well controlled, to ensure that at the end of the installation the bolt has been placed in the working position, which depends on the bolts' relative position to the two parts of the assembly. This is even more complicated if this union between pieces uses more than one bolt, because to achieve correct clamping in this case each individual bolt has to start threading into both receptacle threads simultaneously and be threaded in simultaneously as the receptacle threads approach one another as not to cause binding of the bolts.
  • mounting also requires elastic deformation of the receptacle object to reach the position where the bolt, coming from outside, engages both receptacle threads simultaneously. Then as the screw advances toward its working position, the slot in the receptacle object will recover its original position.
  • male and female threads can either have the same pitch, corresponding to one of the double-threaded bolt, or two different pitches which correspond with both threads of the bolt.
  • FIG.1 shows a double-threaded bolt (1) and its corresponding nut with concentric external and internal threads with same pitch (2).
  • FIG. 2 shows a cross section of the bolt-nut set.
  • FIG. 3 shows a bicycle crank arm (3) with clamp closure, which makes use of the previous bolt-nut set.
  • FIG. 4 shows a cross section of that crank, practiced at the closure.
  • FIG. 5 shows an alternative setting for a double threaded bolt and corresponding nut assembly having been assembled: the nut has two concentric threads but different pitches from each other, being equal to the two pitches of the bolt.
  • FIG. 6 shows a cross section of the previous assembly.
  • FIG. 7 shows a set of bolt and nut, corresponding to a second alternative configuration : access to the bolt is placed at the same end to the nut.
  • a closing bracket in this case applied to a bicycle crank arm (3), for anchoring to a spindle.
  • a effective thread pitch of 0.5 mm equivalent to the difference between pitches of the two threads of the bolt, since that pitch is relatively small to achieve a strong clamping without applying a large torque on the screw; and relatively large for the slot opening and closing the clamp, the screw does not move too far from its position bulging through the sides of the crank.
  • the bolt is first introduced into the crank, threading down to what will be its final position, after which the nut will be threaded into the crank arm until it contacts the tip of the bolt, at which point the bolt is turned gently as to allow both the nut's outer and inner threads to engage the crank's and bolt's threads simultaneously, being then threaded effortlessly until the end of the nut's thread.

Abstract

La présente invention concerne un système de liaison ou d'assemblage au moyen d'un boulon à double filetage (1), couplé à un écrou respectif (2) incorporant des filets concentriques mâles et femelles. Cet écrou (2), qui facilite l'installation du boulon à double filetage (1), agit comme une douille rapportée, une fois installé. Ceci permet une amélioration significative du boulon à double filetage (1), en facilitant son installation et en augmentant les possibilités d'application.
