Definitions

  • This invention relates to an adjustable riveter comprising a head portion, a handle and a fork-like pressure arm.
  • riveting is widely used to fasten two or more pieces of material by passing the shank of a headed pin (rivet) through a hole in each piece and deforming the end of the pin to form a second head.
  • riveters have been developed to meet this need.
  • none of them can be used both in low and high positions. As such, it is necessary for a worker to carry two kinds of riveters for low and high positions respectively, thus causing much inconvenience to the worker.
  • a riveter has been described (EP-A-036210) having a jaw case, the orientation of which is changeable as desired in accordance with the shape of the work to be riveted.
  • This riveter is comprising a turnable jaw case actuating support member disposed within a forward end portion of a frame main body an mounted on a pivot for supporting a lever on the frame main body, coupling means capable of locking the actuating support member in a plurality of positions relative to the lever and displaced from each other through a predetermined angle ⁇ , a jaw case turnable supported by the actuating support member excentrically of the pivot and reciprocally movable straight by a reciprocal turn of the lever through reciprocal turn of the actuating support member connected to the lever, and a jaw case tubular housing turnably supported by the forward end portion of the frame main body and lockable thereto in a plurality of positions angularly spaced from each other by the same angle as the angle of displacement ⁇ .
  • an object of the present invention to provide an adjustable riveter which can be regulated to adapt to low an high working positions, without the help of any tools and without dismantling any component parts thereof.
  • the adjustable riveter comprises a head portion 1 with a vertical through hole 13.
  • a tubular member 11 is integrally formed with the lower part of the head portion 1.
  • the vertical through hole 13 extends downwardly from the top of the head portion 1 to the tubular member 11 forming a space 15.
  • the inclined surface 16 has a recess with threaded holes 161 at four sides and a through hole 17 at the center.
  • a lever 2 is provided in the space 15 by a pin 21 through a stepped hole 18 of the head portion 1 and a through hole 22 thereof and then kept in position by a sleeve 211 and a retainer ring 212. Both ends of the lever 2 has a lug 23 with a fringe 24 adapted to engage with a slot 21 of the sleeve 12 and a neck 31 of a transmission rod 3.
  • Two axial plates 4 and 5, rectangular in shape, are separately fixed on the recess of the inclined surface 16 of the head portion 1 by screws 41 and 51 and a recess 61 in the front portion of a handle 6.
  • the axial plate 4 is further formed with two blind holes 42 for receiving two compressed springs 43 and steel balls 44.
  • the axial plate 5 is also formed with corresponding grooves 52 for confining the compressed springs 43 and steel balls 44.
  • the axial plates 4 and 5 have two center holes 45 and 53 so that a threaded sleeve 7 can be inserted through a hole 62 of the handle 6 and the center holes 45 and 53 of the axial plates 4 and 5 and the center hole 17 of the head portion 1 and then engaged with a nut 71.
  • the transmission rod 3 extends through the above-mentioed parts and connects with a joint 8 at the threaded end 32 thereof. On the lower part of the transmission rod 32 there are two separated fringes 33 and 34 forming a space therebetween.
  • the handle 6 has a front end with an inclination of 45 degrees and a stopper 63 at the other end. On two vertical arms 64 of the handle 6 there is a stepped hole 641.
  • a pin 641 extends through the hole 93 of the front curved portion 921 and out of the vertical plate 64 of the handle 6 to engage with a collar 642 and is kept in position by a retainer ring 643.
  • a pin 941 passes through the hole 94 of the rear curved portion 922 and an elongated slot 81 of the joint 8 thereby enabling the joint 8 to move along the handle 9.
  • the lever when not in use, the lever will urge the sleeve 12 to move to the lower position and the transmission rod is disposed at the upper position.
  • the sleeve carries a rivet
  • press the press arm which will in turn force the transmission rod to move downwards.
  • the lever will be activated to turn upwards via the stepped pin thereby achieveing the purpose of riveting.
