Definitions

  • the invention relates to a torch comprising an elongated hollow body forming a handle, a gripping or gripping zone extending over a fraction of its length is intended to be surrounded by the hand of a user, an elongated nozzle extending the body. at a front end thereof and adapted to emit a flame from its free end, and two operating members for controlling the supply of combustible gas, mounted on the body, namely a first clean operating member to cause the opening of a supply circuit under the pressure of the hand which surrounds the gripping area, and the closing of the circuit by the release of this pressure, and a second operating member located in front of the outlet, to ensure adjustment of the gas flow rate.
  • the actuator for adjusting the gas flow allows, by controlling the power of the flame produced, to perform the different types of work that these installations involve: soft soldering and strong soldering of pipes of different diameters, softening of materials plastics, etc ..., without the need for different torches.
  • the object of the invention is to respond to a large extent to the above requirements.
  • the adjustment operating member comprises a drive element which can move along the wall of the body, and arranged so as to be driven by at minus one finger of the hand surrounding the grip area.
  • a torch can be operated by the only hand which holds the handle, at least one finger of this hand ensuring the adjustment of the gas flow rate, if necessary at the same time as the tightening of the hand keeps the circuit open.
  • the first operating member is located on a ventral side of the body, and the drive element of the second operating member is arranged on the dorsal side of the body so as to be driven by the thumb. Fingers other than the thumb can then rest on the first operating member, leaving the free thumb to drive the second operating member.
  • the adjustment operating member is moves in a rotational movement around an axis passing through the body longitudinally.
  • Such a movement is convenient to carry out using the thumb placed on the dorsal side of the body, and further allows a configuration of the torch giving it other favorable characteristics of use, as will be seen below.
  • the drive element of the adjusting actuator has, for example, the form of a radial projection, which can be formed from an internal element of the actuator having a surface area of revolution, and passing through a lumen formed in the back wall of the body, which is at least partially closed by said internal element.
  • the closing operating member is elongated in the longitudinal direction of the body and articulated at one of its ends relative to the latter.
  • the invention provides for the latter a locking element in the closed position, this locking element can not be easily released using one of the fingers of the hand surrounding the gripping area when this hand is in a position such that the nozzle is directed opposite the body of the user. This is a safety provision to prevent an inexperienced manipulator from inadvertently lighting the torch by directing the nozzle towards it.
  • the locking element may in particular be an elastic tab formed in one piece with the closing operation, at the front end thereof.
  • the torch comprises a gas injector capable of producing a jet of combustible gas and a mixing tube, one upstream end of which is arranged so as to receive said jet and air entrained by that -ci and whose opposite end opens into the nozzle, the injector and the upstream end of the mixing tube being placed inside the body gripping area.
  • the arrangement of the upstream end of the mixing tube inside the grip zone, and therefore behind the adjusting actuator, makes it possible to reconcile a small longitudinal space requirement of the torch and a sufficient length of the mixing tube. to ensure a homogeneous mixture of fuel gas and primary air.
  • the injector and the upstream end of the mixing tube are arranged at a distance from each other in the direction of injection and define between them, in the extension of the wall of the tube, an uninterrupted annular opening for the entry of primary air into it.
  • This arrangement increases the maximum possible primary air flow and therefore the maximum power of the torch.
  • the optimal configuration of the torch according to the invention further comprises the following characteristics: - The jet of gas is oriented along an axis distinct from the axis of rotation of the adjusting actuator and substantially parallel thereto; - the mixing tube passes through the rotary adjustment operating member; - The mixing tube passes through the adjusting actuating member between the axis of rotation thereof and the back wall of the body.
  • the closing operating member has a housing receiving a piezoelectric igniter comprising an elongated housing and an elastic return push-button located at one end of the housing, so that the latter is oriented substantially in the dorso-ventral direction of the body, the closing operating member and the mixing tube constituting longitudinal stops for the igniter.
  • the igniter is actuated directly by compression between the fixed mixing tube and the closing operating member which moves towards the interior of the body.
  • the housing of the igniter in the closing operating member dispenses with the need for retaining means for the igniter in the body.
  • the bottom of the igniter box which is electrically conductive and constitutes one of the electric poles of the igniter, comes into direct contact with the mixing tube, also conductive, the opposite pole being constituted by an electrode mounted in isolation in an opening in the wall of the mixing tube, a short distance downstream from its contact area with the bottom of the housing, and inside the body.
  • the ignition circuit is particularly short, which increases the power and therefore the efficiency of the spark produced.
  • the electrode is mechanically protected by its position inside the body.
  • the adjustment operating member is connected to a tap flow control located inside the body, near the rear end thereof, via a transmission element.
  • the arrangement of the regulating valve at the rear of the body allows the injector to be placed in the intake zone, as indicated above, without complicating the gas circuit.
  • the transmission element then makes it possible to transmit the movement of the operating member located at the front of the body to the tap located at the rear.
  • This transmission element is advantageously a transmission shaft rotating around the axis of rotation of the adjusting actuator, and may be secured to a screw whose screwing pushes a shutter in the direction of a valve seat for reduce the gas flow.
  • This arrangement provides very simple conversion of the rotational movement of the operating member into the conventional translational movement of the shutter.
  • the regulating valve forms part of a compact block disposed internally at the rear of the body and further comprising a gas stop valve controlled by the closing operating member, an element of clean gas inlet to be connected to a supply pipe, and the gas injector.
  • the compact unit can also comprise a gas pressure adapter such as a pressure reducer placed immediately at the inlet.
  • a gas pressure adapter such as a pressure reducer placed immediately at the inlet.
  • the function of such a pressure adapter is to lower the pressure of the gas arriving at the inlet element when it is too high, and in particular makes it possible to supply the torch indifferently from propane, butane or butane-propane mixtures liquefied at different temperatures, without affecting or only slightly affecting the characteristics of use of the torch.
  • a pressure adapter incorporated in the compact block is only useful if the gas tank is not itself equipped with a regulator.
  • the compact block comprises a single piece in which are formed different bores for housing the gas inlet element and the injector and for defining the seats of the regulating valve and of the shut-off valve, as well as to allow gas circulation between these elements.

  • the rear end of the tube 73 is spaced from the injector 34 in the longitudinal direction and is centered by internal projections 71 of the body 1, which is spaced radially from the injector. In this way an uninterrupted annular opening 70 is present between the injector and the end of the tube, which allows unimpeded entry of primary air.
  • the tube 73 bends downward to engage coaxially in the nozzle 2 where it extends beyond the front end 3 of the handle.
  • the front end 74 of the tube 73 is flared to the inside diameter of the nozzle so as to ensure the centering of the latter which is cantilevered at the end of the handle.

  • One of the poles of the igniter consists of an electrode 83 mounted by an insulating bushing in the wall of the tube 73 and extending inside thereof, in its part oriented along the axis 4 of the nozzle and inside the body 1.
  • the other pole is constituted by the metal bottom of the housing 81, which is in direct contact with the mixing tube in a zone distant from the electrode 83 about 40 mm depending on the length of the tube. Given the length of the wire connecting the electrode 83 to the igniter housing, the total length of the ignition circuit is limited to approximately 100 mm.
  • An elastic tab 72 formed in one piece with the lever 75 and depending forwards from the front wall of the housing 79 projects downward relative to the body 1, in the low position of the lever, and cooperates with the body to lock it in this position. To be able to raise the lever towards the inside of the handle, it must be unlocked by pushing the projecting end of the tab 72 backwards to flex the latter elastically.
  • This movement can be carried out conveniently by the index finger of the hand holding the handle, when the nozzle is turned away from the body of the manipulator. If on the contrary the nozzle is turned towards the user, the flexion of the wrist necessary to obtain this orientation causes a displacement of the fingers relative to the lever which makes this unlocking movement difficult, if not impossible.

  • a front panel 89, located in front of the walls of the housing 79 of the lever 75, has a stud 90 directed forward and guided in rotation around the axis 41 in a bearing 91 of the handle.
  • a rear wall 92 located behind the walls 78 of the housing 79, is integral with a sleeve 93 having along the axis 41 a bore of hexagonal section in which the front end 94, also of hexagonal section, d 'a transmission shaft 95 extending along the axis 41 and secured to the screw 48 by its rear end which is tightened by a transverse screw 96 ( Figure 4) in a blind axial bore 97 of the screw 48.
  • the sails 89 and 92 have arc-shaped openings 98 for the passage of the tube 73.
  • buttons 84 From the cylindrical portion 85 of the button 84 depends, at one of its circumferential ends, an elastic tab 99 whose free end 100 cooperates with notches 101 formed on the internal wall of the corresponding half-shell 1a of the handle 1 to define a multiplicity of stable button positions.
  • each of the two half-shells 1a and 1b has two projections 102 located respectively on the dorsal side and on the ventral side, extending substantially up to the same distance from the plane of symmetry P, which distance is greater than half the size of the torch in the direction perpendicular to this plane, at its rear end.
  • the torch whose center of gravity is located behind the feet 102 thanks in particular to the position of the compact block 5, can thus be placed stably on a horizontal surface by resting there by the two projections 102 of one of its sides and by its rear end, the plane P, which contains the axis 4 of the nozzle, deviating from the rear support surface in front of the torch so that the nozzle is kept spaced from this surface.
  • FIG. 3 shows a stamped metal part 103 which contributes to the mutual connection of the half-shells 1a and 1b and to the centering of the block 5 in the body, and further immobilizes the bush 12 in rotation.
  • the piece 103 has ears 104 extending parallel to the plane of symmetry P and penetrating, from the inside of the body 1, into orifices formed in the thickness of the half-shells 1a and 1b respectively, thus ensuring their joining mutual.
  • Exhibit 103 presents moreover, a twelve-sided opening 105 in which a hexagonal part of the sleeve 12 adjusts adjacent to the rear face 9 of the one-piece part 6, thus ensuring the centering and the braking in rotation of the sleeve.
  • the positioning of the block 5 in the body 1 is completed by appropriate internal projections provided on the half-shells 1a and 1b. Furthermore the recess 11 of the part 5 allows the passage of one of the assembly screws 1c of these half-shells.

  • the sleeve 12 and the elements 19 to 26 associated with it constitute a pressure reducer which, when a pressurized combustible gas arrives inside the sleeve, routes it into the annular space 14 under a desired pressure.
  • the adjustment of the gas flow rate using the button 84 can be carried out either when the torch is off or on.
  • the rotation of the button over an amplitude of approximately 60 °, causes a corresponding rotation of the screw 48, which is screwed and unscrewed in the part 42 of the bore 40 over a length of approximately 0.17 mm.
  • the seal 46 is crushed against the crevices of the frustoconical seat 44 and reduces the gas flow rate without, however, canceling it out.
  • the screw is unscrewed, the elasticity of the seal pushes the piston 47 forward and the flow rate increases. During this movement, the part 94 of the rod 95 slides in the sleeve 93 of the adjustment button.
  • the block 5 ′ shown in FIG. 5 differs from the block 5 in FIG. 4 only in that the shape of the bore 7 ′ of the one-piece part 6 ′ is modified with respect to at the bore 7 of the part 6, and in that the seal 19, the ball 20, the springs 21 and 26, the piston 24 and the O-ring associated therewith are eliminated. All the other elements, which are common to the two blocks, will not be described again.
  • the particular shape of the bore of the sleeve 12, described in relation to FIG. 4, is unnecessary here, but its use dispenses with having to provide a different sleeve for this variant of the block.
  • the bore 7 ′ is similar to the bore 7 in the rear part thereof which houses the sleeve 12, but the front part, which houses the piston 24 and the spring 26 and opens laterally into the recess 11, is deleted.
  • the bore 7 ′ is therefore blind.
  • Block 5 ′ works in the same way as block 5, except that the expansion function is eliminated, the gas arriving without reducing pressure in the space 14 ′ surrounding the front part of the socket 12 and at the inlet bore 49.
  • This block is intended to be used with a gas tank, the outlet of which is equipped with a regulator. Parts 6 and 6 ′ can be obtained from the same molding blank.
  • the relative arrangement of the various elements of the torch according to the invention makes it a light, compact tool, well in hand, easy to use and requiring no precautions. It is particularly suitable for sanitary installers, whose various operations can be carried out by the simple operation of the adjustment button. To this end, the latter and the handle 1 may have means, not shown, for the visual identification of different predetermined positions of the button corresponding to the most common operations, for example: hard soldering and soft soldering of pipes of different diameters; softens plastics.
  • the first operating member can be in a position other than ventral, for example dorsal, in which case it would be actuated by the pressure of the palm.
  • the drive element of the second operating member can be in a ventral position, to be actuated by the index finger of the hand, or lateral, to be actuated either by the index finger or by the thumb. It is even possible to provide two drive elements placed respectively on the left and right sides to allow the operation to be chosen using the thumb and / or the index finger of the same hand, or to allow the use of the torch in the same conditions using the right hand or the left hand.
  • Means can also be provided to limit the entry of primary air to low gas flow rates so as to facilitate the ignition of the flame.
  • Such means can be constituted by a shutter integral with the adjusting screw 48 and partially closing off the annular air inlet passage 70.
