Definitions

  • the present invention relates to a sealing device according to the preamble of claim 1.
  • This device is intended to anchor fastening elements in hard materials, such as concrete and cement, wood, steel, or materials. analogues.
  • the apparatus of British patent GB-A-834,293 comprises a counterweight arranged to receive a fixing element, the assembly of the counterweight and this element prior to firing constituting a long operation. After firing the device, the separation of the two parts, if at all possible, is even worse. In addition, many weights must be available, as well as fixing elements of different diameters. Finally, we did not have with this device suitable elements for driving nails. Such drawbacks have therefore led to the abandonment of such a device.
  • the apparatus of the German patent DE-B-1 224 218 comprises a counterweight provided with a housing intended to receive the head of a fixing element and therefore to center it using a washer of sufficiently flexible plastic material to slide inside two bores of different diameters.
  • the fastening assembly made with such a device is not so good and in addition one must use a special rod to introduce a fastening element into the device and return the weight to its firing position.
  • the apparatus of British patents GB-A-734,344 and GB-A-901,023 comprises a fixing element with two centering means, the first consisting of the tip guide for guiding a washer mounted on the rod portion of the fixing element according to patent GB-A-734,344, the second centering means being constituted by the head portion of the fixing element, or a cap mounted on it, cooperating with the tip guide, whereas according to GB-A-901 023, the second centering means is constituted by a housing extending in the front end of the counterweight and receiving the head of the fixing element or a projecting portion extending back from the back end of it.
  • the front end of the counterweight before firing is arranged and centered in the tip guide and therefore the length of the stem of the counterweight which slides in the tip guide must be substantially greater than the length of the longest fastener to be anchored by the device. Consequently, these devices are limited in size as regards the length of the fastening elements since long fastening elements would lead to devices of considerable length with a heavy flyweight.
  • the present invention therefore aims to solve the problems which have arisen on the devices of the prior art.
  • the counterweight using its rear portion, can be guided in the bore in which this rear portion slides, while the fixing element introduced into the bore receiving the front portion of the counterweight is centered on its entire length without the need for a long flyweight. Consequently, the invention provides a relatively short device for anchoring long fastening elements with complete centering of these elements during their driving movement.
  • the wall formed at the front end of the rear driven and guided portion of the counterweight and by the wall formed at the rear end of the front drive portion of the counterweight.
  • These walls can be used in conjunction with a damping effect, a power adjustment, a safety effect, the ejection of the fastening elements, etc.
  • the length of one of the bores can be adjustable, while the length of the other remains constant or can also be adjustable.
  • the apparatus of the invention comprises a barrel tube 1 to the interior of which is disposed an elongated element 3 fixed to the tube 1 by means of a screw 2.
  • the elongated element 3 comprises two bores 4 and 5longitudinal and intersecting, the bore 4 being closed at the left end, in the figure, while the bore 5 is closed at the right end in the figure.
  • a sleeve 7 is screwed onto the tube 1 and comprises a bore 6 aligned with the bore 4 of the element 3, the bores 4 and 6 having the same diameter.
  • a bore 8 of smaller diameter than bore 6 is formed behind bore 6 to receive a cartridge support 9 provided with a central bore forming a combustion chamber 10 for a cartridge 11.
  • a counterweight 12 having a rear portion 13 and a front portion 14 is slidably mounted inside the elongated element 3.
  • the rear portion 13 is slidably mounted in the bores 6 and 4 and the front portion is slidably mounted in the bore 5.
  • the rear portion 13, when the appliance is ignited, is driven by the pressure of the combustion gases, while the front portion 14 drives a fixing element, not shown, having been previously introduced into the bore 5, between the front end 18 of the element 3 and the front end 17 of the front portion 14 of the counterweight 12.
  • a wall 15 is provided at the front end of the rear portion 13 of the counterweight 12.
  • the counterweight 12 comprises a rear portion 13, a front portion 14 offset transversely relative to the longitudinal direction of the barrel and shaped to slide respectively in the two bores 4 and 5.
  • the front end of the bore 4 in which slides the rear portion 13 of the counterweight 12 is arranged in front of the rear end of the bore 5 in which the front portion 14 of the counterweight 12 slides.
  • the bore 23 In its front region, as can be seen in fig. 2, the bore 23 has a semi-cylindrical wall extended by two parallel flat walls and spaced apart by a distance equal to the diameter of this cylindrical wall mentioned above. In the region of intersection of the bores 4 and 5, two portions 22 of the cylindrical wall remain, as can be seen in FIG. 3, and the head 20 and the washer 21 of the fixing element 19 bear against these two portions 22 as well as against the inner wall of the element 3.
  • the counterweight 12 has a second rear portion 24 slidably mounted in a bore 25 aligned with the bore 5.
  • the bore 25 may even extend through the handle, not shown, of the device and the portion 24 can be long enough so that part of it is never exposed to the action of the combustion gases.
  • the rear end of the portion 24 may have the shape of a truncated cone arranged to cooperate, when the counterweight is in its rear position, with a corresponding truncated cone formed in a recess in the device.
  • the frictional cooperation of the rear end of the portion 24 of the counterweight 12 and of the housing in the device prevents the counterweight from moving during the handling of the device, and also makes it possible to obtain a ballistic effect in the measurement where the flyweight only starts to move from a predetermined pressure prevailing in the combustion chamber after the ignition of the appliance.
  • the rear portion 24 can also be combined with an adjustable stop so as to vary the volume between the rear end of the rear portion 13 of the counterweight 12 and the cartridge 11.
  • the rear portion 24 may also include means arranged to pull the counterweight 12 after the use of the device. This can be done manually or automatically by opening the device. These means may have the form of an element projecting transversely to the device and provided at the rear end of the portion 24 which, when the device is opened, abuts against a fixed portion of the handle of the 'apparatus. When the barrel 1 slides forward, to the left in the drawings, the counterweight 12 is moved through the bores 4, 5 and 6 in its rear firing position.
  • This projecting element is arranged to bear against a fixed part located, before the propulsion of the counterweight 12, at a distance from this projecting element less than the distance separating the front end, from the bore 4 in which slides the rear portion 13 of the counterweight 12, and the front end of the rear portion 13 of the counterweight 12.
  • This projecting element can be fixed to the portion 24 so detachable. It is also possible to provide that said fixed part is fixed to the device in a detachable manner. Thus, this projecting element is used as a stop for the counterweight when the cartridge has supplied too much energy.
  • This projecting element or this portion fixed to the handle of the device can be arranged to be sheared.
  • spring means can be provided between this projecting element and the portion fixed to the handle of the device.
  • the second rear portion 24 can also serve as a safety device when the device is dropped, or as a retaining means, preventing the counterweight from moving if the cartridge is ignited.
  • a groove can be made on the portion 24 to receive a locking element or a trigger in order to retain the counterweight as long as the trigger has not actuated the trigger to release it from this groove.
  • the bore 25 is open at the rear part of the handle of the apparatus, a rod of suitable size can be introduced into this bore to push the counterweight 12, whether or not it is provided with this portion 24.
  • a fastener which has been wrongly inserted into the device may be ejected.
  • the front wall 15 of the counterweight 12 can advantageously constitute stop means for the counterweight when the energy of the cartridge is too high.
  • This wall can be arranged to receive by screwing a small piston 26 intended to be received in a housing 27, of the same section, formed in the wall 16 of the elongate element 3, thus making it possible to obtain pneumatic damping.
  • the housing 27 can also be filled with an elastic material. The means 26 and 27 can be reversed, the small piston then being fixed to the wall 16.
  • the small piston and its housing can be used as a hammer and anvil for a metal washer disposed in a slot 28 formed in the wall 16.
  • This front portion 16 of the element 3 can also be mounted to slide against the action of elastic means. an external depreciation system.
  • the relative position of the front wall 18 and of the remaining elements of the apparatus can vary so as to control the overpower of the front portion 14 of the counterweight 12.
  • the counterweight 12 can be formed from different assembled parts, damping means being able to be interposed between these parts.
  • the central part of the counterweight 12 can be weakened in an appropriate place, so as to retain inside the barrel of the apparatus, in the event of a fracture, a broken part of this counterweight.
