  • Patent Citation 1 Japanese Laid-Open Patent Publication No. 2002-122114[Patent Citation 2] Japanese Laid-Open Patent Publication No. 2005-61613 Disclosure of Invention Technical Problem
  • the present invention has been made to solve the problems residing in the prior arts described above, and an objective thereof is to provide a fastening device which has neither the need of machining the shaft portion of the bolt to drastically reduce its diameter for the purpose of accommodating the fitting tolerance, nor the need of a large space between two members.
  • the fastening device of the present invention is to tighten a first member and a second member spaced from each other while keeping them spaced at their mutual distance, the fastening device comprising: a nut fixed to said first member; a holder fixed to said first member; an adjuster nut held so as to be unrotatable but movable in an axial direction within said holder; a bolt inserted from said second member toward said first member; and a collar bolt temporarily screwed to a male screw portion of said bolt via torque-transmitting means, said collar bolt being formed with a male screw portion on its outer periphery to be screwed to said adjuster nut, wherein said fastening device has a function of moving said adjuster nut to a position at which it comes into contact with said second member by further rotating said collar bolt after its top end is seated on said first member.
  • all of the screw portions are threads of same direction. It is also preferable that the holder includes clip claws to be engaged with the attachment holes of the first member. Further, it is preferable that the male screw portion of the collar bolt is formed at the head portion close to the second member.
  • a nut is provided to the first member which is one of the members, and the bolt and the collar bolt are fixed on the same axial line as of the nut. Due to this arrangement, even if there is a fitting tolerance, if the through hole of the second member is formed in a size with some extra space, there is no need of machining the shaft portion of the bolt to drastically reduce its diameter for the purpose of accommodating the fitting tolerance, unlike the case of Patent Citation 1.
  • the fastening device of the present invention has a structure in which the adjuster nut is moved toward the head portion of the collar bolt so as to eliminate the gap between the first member and the second member.
  • the fitting length corresponding to the height of the adjuster nut can always be ensured between the adjuster nut and the collar bolt even after the adjuster nut is moved.
  • the collar bolt does not need to have a long axial length, resulting in reduction of the length of the fastening device.
  • a large space is not required between the first and second members.
  • the adjuster nut since the adjuster nut does not have to be a left-handed thread, a thread rolling dice for left-handed thread is not required, and the manufacturing cost can be suppressed.
  • FIG. 1 is a perspective view showing a fastening device according to an embodiment of the present invention in an exploded state.
  • Fig. 2 is a cross-sectional view of a holder holding an adjuster nut.
  • Fig. 3 is a plan view of a holder.
  • Fig. 4 is a cross-sectional view showing an initial state of tightening by means of a fastening device.

  • FIG. 8 is a cross-sectional view for illustrating a prior art.
  • FIG. 9 is a cross-sectional view for illustrating another prior art. Best Mode for Carrying Out the Invention
  • a fastening device of this embodiment comprises a metallic bolt 1, a metallic collar bolt 2, a metallic adjuster nut 3, a resin holder 4, and a metallic nut 5.
  • a member to which the holder 4 and the nut 5 are to be fixed will be referred to as a first member Pl
  • a member into which the bolt 1 is to be inserted will be referred to as a second member P2 (whose illustration is omitted in Fig. 1)
  • the bolt 1 is comprised of a head portion 10 having a large diameter, a circular column-like shaft portion 11, and a male screw portion 12 having a right-handed thread spirally formed at the top end side of the shaft portion 11.
  • a column-like top portion 13 having a diameter smaller than that of the male screw portion 12 is formed to facilitate insertion and screwing to the collar bolt 2 and the nut 5. There is no need of machining the circular column-like shaft portion 11 to drastically reduce its diameter.
  • the collar bolt 2 is formed with a female screw portion 21 on its inner surface, and a male screw portion 22 on its outer surface. Both of these screw portions are right- handed threads.
  • the female screw portion 21 is formed by a several number of pitches at the side of head portion that is close to the second member, and the male screw portion 22 is also formed at the side of head portion close to the second member.
  • the screw portion serves to reduce the number of rotation of the bolt 1 required until the tightening is completed, so as to enhance the workability.
  • the female screw portion 21 of the collar bolt 2 can be screwed to the male screw portion 12 of the bolt 1 via a torque-transmitting means, and can rotate together with the bolt 1 in the initial stage.
  • the torque-transmitting means has a function of permitting the bolt 1 to transmit a torque up to a predetermined value to the collar bolt 2, and when the torque has exceeded a predetermined value, it enables only the bolt 1 to rotate.
  • the torque-transmitting means is an adhesive agent applied to the male screw portion 12 of the bolt 1, or alternatively, a deformed portion formed by crushing a part of the threads so as to impart resistance thereto. Since thus-structured torque-transmitting means fixes and screws the collar bolt 2 to the bolt 1 temporarily, the collar bolt 2 is never detached from the bolt 1 by vibration generated during the transportation.
  • a nut 5 On the back surface of a through hole 52 formed on the first member Pl (i.e. a surface at the side remote from the second member P2), a nut 5 is fixed by, for example, welding. On the front surface (i.e. a surface facing to the second member P2) of the first member Pl, a holder 4 is fixed.
  • the nut 5 is a right-handed threaded nut, and has a female screw portion 51 that is capable of screwing to the male screw portion 12 of the bolt 1.
  • the holder 4 is a resin member including a plurality of clip claws 41 to be engaged with attachment holes 8 of the first member Pl.
  • the holder 4 is in a hexagonal tubular shape, incorporating in it a hexagonal adjuster nut 3 in a manner un- rotatable but movable in the axial direction.
  • the material of the holder may be any other materials such as an aluminum, a cast iron and the like. Due to this arrangement, the adjuster nut 3 never detaches from the holder 4 due to the vibration and the like generated during transportation.
  • the adjuster nut 3 is detached from the holder 4 if a predetermined force is applied, and only the adjuster nut 3 can be moved in the axial direction.
  • the holder 4 and the adjuster nut 3 are not limited only to the hexagonal tubular shape, but may be in any other polygonal tubular shapes such as a triangular tube, a rectangular tube, and the like, or alternatively, may be in a structure which is unrotatable but movable in the axial direction by a locking engagement.
  • the first member Pl is a side plate of an automobile, for example, and the second member P2 is a front pillar of the automobile, for example.
  • the clip claws 41 of the holder 4 are elastically deformed to fit into the attachment holes 8 of the first member Pl, so that the holder 4 is fixed to the first member Pl.
  • the adjuster nut 3 is held within the holder 4. At this time, the bottom surface of the adjuster nut 3 is in a seated state on the first member Pl.
  • the bolt 1, furnished with the collar bolt 2 is inserted into the through hole 9 penetrated through the second member P2.
  • the male screw portion 22 formed on the substantially upper half portion of the collar bolt 2 is screwed to the female screw portion 31 of the adjuster nut 3.
  • the male screw portion 22 of the collar bolt 2 has reached the state in which it is screwed to the female screw portion 31 of the adjuster nut 3 in some pitches.
  • the bolt 1 is further rotated after the top end of the collar bolt 2 has come into contact with the first member Pl. Since the collar bolt 2 cannot advance any more, it will rotate as staying at the same position. Thereby, the adjuster nut 3, screwed to the male screw portion 22 of the collar bolt 2, moves toward the second member P2, so that the upper end of the adjuster nut 3 comes into contact with the second member P2 as shown in Fig. 6. This movement of the adjuster nut 3 also serves to always ensure the fitting length between the adjuster nut 3 and the collar bolt. [0023] When the state as shown in Fig.
  • neither the collar bolt 2 nor the adjuster nut 3 can move any more, and the adjuster nut 3 and the collar bolt 2 together create a state in which the gap between the first member Pl and the second member P2 is fixed.
  • a torque exceeding a predetermined value acts between the collar bolt 2 and the bolt 1.
  • the torque-transmitting means is released and the male screw portion 22 of the bolt 1 will be screwed into the female screw portion 21 of the collar bolt 2.
  • the male screw portion 12 of the bolt 1 comes off from the female screw portion 21 of the collar bolt 2, and in turn, will be inserted and screwed to the female screw portion 51 of the nut 5 of the first member Pl.
  • the head portion 10 of the bolt 1 is brought into contact with the second member P2, so that the first member Pl and the second member P2 will be tightened to each other while being kept spaced at a certain distance as shown in Fig. 7.
  • the through hole 9 of the second member P2 is in a size with some extra space, the bolt 1 and the collar bolt 2 can move freely within the through hole 9 of the second member P2.
  • the centers of the nut 5 of the first member Pl and the through hole 9 of the second member P2 are not precisely aligned to each other.
  • the fastening device of the present invention can fix the first member Pl and the second member P2 to each other while keeping the distance between them. Further, the bolt 1 and the collar bolt 2 are fixed on the same axial line of the nut 5 of the first member Pl.
  • the through hole 9 of the second member P2 is formed in a size with some extra space, there is no need of machining the bolt 1 to drastically reduce its diameter for the purpose of accommodating the fitting tolerance.
  • interference between the shaft portion of the bolt 1 and the female screw 21 needs to be avoided either by slightly reducing the diameter of the bolt 1 or by increasing the inner diameter of the female screw 21.
  • the adjuster nut 3 moves toward the base portion of the collar bolt 2, that is, toward the second member, the fitting length can always be ensured between the adjuster nut 3 and the collar bolt 2, and thus, there is no need for the adjuster nut 3 to have a shape extending longitudinally. Due to this structure, a large space is not needed between the first member Pl and the second member P2. Further, since all of the screws can be formed into a right-handed thread, there is no need of a thread rolling dice for left-handed thread, and the manufacturing cost can be reduced. As described above, many advantages can be obtained.
