Definitions

  • the present invention relates to an indirect fire sealing apparatus as defined by the characteristics of the preamble to the claim 1.
  • Such a device is used for, for example, fixing steel plates on metal or concrete support structures for mounting roofs or floors.
  • a buffer As a buffer, it is generally used a buffer comprising a rod, an end head, with which the counterweight is intended to cooperate, and a centering washer, of the same section as the head, mounted on the rod between the head and its penetration end.
  • the drive of the buffer by the counterweight would cause the attachment of the head or of the pad washer to the rim of the bore of the pad guide downstream of the shuttle and would destroy the pad.
  • the present invention aims to eliminate such a risk.
  • the invention relates to an apparatus of the type mentioned in claim 1.
  • the invention therefore provides, at the end of the action of the means for controlling the means for closing the combustion chamber and means for displacement of the shuttle, to dissociate the displacement of the shuttle from the chamber closed.
  • the invention provides for a displacement stroke additional, or "overtravel", of the shuttle, in which it is therefore never trained, and which compensates for manufacturing tolerances and the play caused by the wear of the parts, thus anticipated.
  • the means of movement of the shuttle include a drive drawer mounted movable in the shuttle against the action of damping return means, the drawer moving in the shuttle as soon as it stops in its firing position, the damping means thus being arranged at the end of a kinematic chain of displacement of the shuttle.
  • damping means could be imagined such as, for example, a shock absorbing spring inside the kinematic chain of moving the shuttle.
  • the apparatus comprises a rear handle 1 and a side handle 2, a combustion chamber 3, with its cover 4, its push-button 9 for opening the hood, its wheel 10 and its slider 5 for adjusting power, a trigger 6, a buffer guide 7, a tube 8 for feeding buffers, a shuttle displacement rod 11.
  • the combustion chamber 3 is provided at the rear of the barrel 60, of the front end of which is attached the buffer guide 7.
  • the barrel 60 is mounted sliding in a gun holder 61 intended to receive, before closing the cover 4, a cartridge disc 62, one of which is intended to be covered by the barrel 60 in firing and closing position of the combustion chamber 3.
  • the gun holder 61, axis 20, carries a finger 63 for controlling the movement a buffer loading shuttle.
  • the finger 63 extends, on the side of the gun holder, parallel to its axis 20.
  • the device is a standing fire device.
  • the sealing pads are inserted into tube 8.
  • the operator by the handles 1, 2, puts the device pressing against the support material intended to receive the tampon and press on the device to lower the barrel holder against the action of springs 61 towards the buffer guide 7.
  • the rear of the barrel comes cover a cartridge and close chamber 3 and finger 63 goes down to actuate the rod 11.
  • the firing is carried out by the trigger 6.
  • the operator takes out the bearing.
  • the buffer guide 7 essentially comprises three bores.
  • a third through bore 26 extends, on the side of the buffer guide, parallel to the central bore 21, 22. It receives the rod 11 of shuttle movement. As this one is itself moved against the action of a compression spring 27, the bore 26 has a portion enlarged 28, for this spring 27, extending between the shoulder formed between the two bore portions 26, 28 and the head 29 of the rod 11.
  • the buffer guide Between the inner end 30 of the tampon guide, through which the central bore portion 22 of narrowed section, and the mouth of the bore transverse 23, the buffer guide has a passage opening for pad around which the end piece 31 of the supply tube 8 is fixed.
  • the shuttle 34 shaped to slide in the bore 23, comprises essentially two sleeves juxtaposed and orthogonal to each other.
  • a first outer sleeve 32 which receives a displacement drawer 33, and the bore 23 are coaxial.
  • a second inner sleeve 35 has a parallel axis to axis 20 of the device.
  • the central bore of the sleeve 32 has a portion outer 36 of enlarged section to receive, between the shoulder between the two bore portions and the head 37 of the drawer 33, a spring compression damper 38.
  • the central bore of the sleeve 35 has a section corresponding to that of the buffers.
  • the pads have a rod 39, with a head 40 and a pointed end 41.
  • a centering washer 42 with the same outside diameter that the head 40 is slid over the rod 39.
  • the shuttle displacement rod 11 carries a lug 43 extending through a light 44 formed in one of the arms 45 of a link 46, with two arms in V 45, 47, pivotally mounted around an axis 48, driven into the buffer guide 7 and orthogonal to the axis 20 of the device and to the axis of the bore of shuttle 23.
  • the link 46 is articulated to another link 49 whose end free carries a displacement lug 50 extending through a light of the outer shuttle sleeve 32 and integral with the drawer 33.
  • the gun holder 61 slides on the barrel 60 to, on the one hand, order the closing of the chamber combustion 3, by covering the barrel by the barrel holder, and, on the other hand, control the movement of the shuttle 34 by sliding the finger 63 which causes the rod 11 to slide, which pivots the link 46 which, at its turn, rotates the articulated end to it of the rod 49 which causes the other end of the connecting rod 49 to slide, bearing the lug 50.
  • the rod 11 By sliding, the rod 11 lowers its lug 43 which is forced to slide in the light 44 of the arm 45 of the link 46, which constrains the link 46 to rotate.
  • the cooperation of the lug 43 with the edges of the light 44 and the relative displacement of the rods can cause a widening of this light and play in the rods which could limit the rotation of the rod 46 and therefore the translation of the shuttle 34 if the invention had not been proposed.
  • the spacing, at rest, between the finger 63 and the rod 11 is determined so that the support entails, in addition to closing the combustion chamber 3, the sliding of the rod 11 over a length which, taking into account the arrangement and dimensions of the rods 46, 49, of the light 44 and the position of the lug 43 on the rod 11, should slide the shuttle 34 beyond its abutment shoulder 25.
  • the shuttle 34 abuts on this shoulder, continuing the descent of the rod 11 continues to actuate the kinematic chain of the rods which, by the lug 50, slides in the shuttle 34 the drawer 33 against the action of the spring 38.
  • the head 37 of the drawer 33 is then retracted inside the bore 36 of the shuttle ( Figure 6).
  • the additional shuttle construction run 34, made impossible by the stop 25, is therefore absorbed by the drawer 33 and its spring 38. This additional stroke, or overtravel, therefore makes it possible to overcome the wear of the parts of the kinematic chain for moving the shuttle 34.
  • this comprises a lateral ramp 71 for raising the buffer.
  • a ball 73 buffer retainer subjected to the action of a spring, not shown, for retain the tampon until it is trained when firing.
