Definitions

  • the present invention relates to a hand-operated discharge device for a double discharge cartridge for two-component compositions, each with a push rod for each cartridge and a feed drive which can be actuated via a hand lever and acts jointly on the push rods.
  • a hand-held device is known from DE-A-3 128 611.
  • the push rods can be actuated by a clamping jaw and a bracket by a hand lever, and a counter bearing is provided for lateral support of the push rods, on which the clamping jaws are pivotally mounted.
  • the feed drive acts directly on each push rod, the clamping jaws act laterally on the push rods with the tendency to bend them, even if counter bearings are provided. With great effort, there is a risk that the feed jams.
  • a manually operated discharge device which has a similar feed mechanism as in DE-A-3 128 611 and additionally discloses a retraction brake for each push rod.
  • the device should be able to use double discharge cartridges of different diameters, even under these conditions, in which different reaction forces occur on the push rods, the push rods should be driven synchronously, so that no change in the volumetric mixing ratios occurs.
  • FIG. 1 shows a first exemplary embodiment of a hand-held device 1 with the handle 2, the trigger 3 and the double cartridge 4, which contains two components in a specific ratio, which are mixed during the discharge process in a so-called upstream static mixer, to which they react chemically and harden or solidify.
  • the two components should be discharged from the cylinders by simultaneously actuating delivery pistons arranged in each cylinder, as a result of which the masses are pressed out through the front-side outlet opening 5 of the static mixer.
  • the double cartridge 4 is not actually the subject of the present invention and is, for example, in EP-A-294 672 of the same applicant has been described in detail.
  • the hand-held device according to the invention is not limited to the operation of such double cartridges, but is particularly suitable for this.
  • the masses to be discharged can be quite viscous, so that relatively high forces have to be exerted in order to discharge them.
  • the ejection pistons 6 located in the cartridges are actuated by the pressure pieces 7 at the ends of the push rods 8. These push rods are driven by the trigger 3 via a lever mechanism and thrust member.
  • the trigger 3 is connected to a rotating piece 9, which is rotatably mounted about axis 10 and is connected to a joint 11, the two parts of which are articulated to one another by an axis 12 and the second joint part 13 of which is connected to a joint piece 15 which can be rotated by pivot pin 14 is.
  • the articulated piece 15 in turn acts via its cut-out end 16 on a bolt 17 which runs freely in the cutout 16 and which is arranged at the lower end of the push lever 19 consisting of two plates 18 in FIGS. 1 and 2.
  • the transmission or reduction ratio can be changed in various ways, for example by changing the trigger, by displacing the axis of the joint 11 or, as recorded in the present example, by continuously changing the distance between the axis 12 of the joint 11 and the Axis 14 of the joint piece, by moving the second joint part 13 in the bore 24 of the joint piece 15 by an adjusting screw 25 which is fastened in a corresponding thread in the joint part 13.
  • This set screw 25 is adjustable through an opening 26 in the housing 27.
  • a combination of the proposed measures makes it possible to adjust the reduction ratio, for example, in a range from 7.5: 1 - 25: 1.
  • the push lever 19 is rotatably mounted about the main axis 28, which is arranged in the two-part housing 27.
  • the main bearing 28 consists of two journals 29 which are embedded in the thrust lever plates 18 and run in the housing parts of the housing 27 and a bearing piece 30 which has a recess 31 at the top for the passage of the thrust member 34 and is extended downwards by screws 32 record that connect the bearing piece with the thrust lever plates 18.
  • the force from the trigger lever via various levers to the joint piece 15 and from there to the bolt 17 of the thrust lever 19 is transmitted to the thrust member 34 via the bolt 33, the bolt 33 being arranged in an incision 35 in the thrust member 34, as shown in the figures 1 and 2 emerges.
  • the pushing element 34 is guided on the cartridge side in a cylindrical sliding guide 56 and in a clamping jaw arrangement 36 (see also FIG. 3) and on the other side in a sliding guide 37, which ensures parallel and shear force-free propulsion of the pushing element.
  • the cylindrical slide guide 37 is arranged in the housing 27.
  • a dosing screw 38 is screwed in, with which it is possible to limit the stroke of the thrust piston, whereby the dosing can be finely adjusted.
  • each pawl 40 is U-shaped, see FIG. 1, the short legs 41 pointing towards the cartridge each having a push tooth 42 on the inside.
  • the legs 41 and the push teeth 42 are pressed against each other by means of a compression spring 43 arranged at the other end of the pawl. The force is transmitted from the trigger lever via the joints and the push lever to the push member 34 and from there via the pawl axes 39 to the pawls 40 and thus to the push teeth 42 and from there to the two push rods 8.
  • the push rods 8 point on both sides, ie in Figure 1 front and rear teeth 44 in which the pusher teeth 42 engage to move the pushrod 8 forward, ie towards the cartridge 4.
  • the push rods 8 are guided on the cartridge side and in the rear of the housing 27 and have a hole 46 on the rear connecting part 45 in order to be able to pull the push rod rearward into the starting position.
  • the pawls, or rather the pusher teeth must disengage, which is done by means of the knurled screw 47, which acts on a rectangular axis 48, which occurs when the same is turned the pawls rotates and the pusher teeth are removed from the pushrod teeth 44.
  • the set screw has a locking mechanism consisting of a ball 49, which is under the pressure of a spring 50, in order to lock the set screw in the clamping or release position.
  • the jaw arrangement 36 has two axes 51, on each of which two compression springs 52 are arranged (see FIG. 3), which are located in a corresponding recess 53 in the two jaws 54 and compress the jaws.
  • the force of the compression springs is selected in such a way that the clamping jaws are only pressed together to such an extent that they are able to hold the push piston while the pawls are being returned.
  • FIGS. 7-10 A second exemplary embodiment is shown in FIGS. 7-10, in which the power transmission takes place according to the same principle, but the pawls are not pushed but pulled.
  • the trigger lever 60 which is under the pressure of a spring 59 and is pivotally and movably connected to a pull tab 63 about the axis 62 attached to the housing 61.
  • This pull tab 63 see FIG. 8, is movably connected to two pull levers 65 via an axis 64.
  • the two pull levers 65 are connected to one another by a pull bolt 66 which engages in the middle part of the thrust member 67 in order to push it towards the cartridges 4.
  • the thrust member 67 is provided with two pawl axes 68, around which a pawl 69 can be rotated and are arranged under the pressure of springs 70.
  • the pusher teeth 71 engage in the teeth 72 of the pushrods 73, these being made much thinner than in the previous embodiment.
  • the pawls are not pushed but pulled because they are located behind the pull lever.
  • the excess or reduction ratio from the path of the trigger to the path of the thrust member can be changed by the choice of the pivot point 74, either as shown in FIG. 7 in the middle hole or in the hole 75 or 76 above or below it.
  • the pivot point is fixed by the two screws 77, see Figure 8.
  • the remaining parts of the hand-held device such as clamping jaws, guides 78 and 79 for the pushing element and the end piece for pulling back the pushing rods, are designed in a manner similar to that in the first exemplary embodiment and in this embodiment.

  • the trigger lever 127 is pivotally and movably connected to the two-part housing 131 attached to the two-part housing 131 with two pull tabs 133, which in turn are connected via an axis 134 to two push levers 135.
  • the push levers are rotatable about the fixed axis 136 embedded in the housing.
  • the two thrust levers 135 are connected below the fixed axis 136 by a bolt 138, which acts on a freely movable, short, two-part joint piece 139, which is provided at its other end with a second bolt 140, which is the two joint part parts connects with each other.
  • the bolt 140 is located in an eye 141, which is arranged on the slide 142.
  • the pushing element 142 essentially consists of two triangular side plates 143, see FIG. 11, which are connected to one another on the cartridge side via an end wall 144 and on the other side via a web 145 in order to give a rigid frame, and an elongated hole 137 for each Have recording of the axis 136.
  • the eye 141 is arranged on the front side 144, see FIG. 12.
  • the two side plates 143 are, according to FIG. 13, in the two housing sides 146 of the housing 131 guided.
  • the guides 147 fastened on the inside of the housing can consist of plastic or bronze, while the side parts of the thrust member can consist of aluminum, for example.
  • a push tooth holder 148 which is under spring pressure, is arranged on both sides of each push rod on the cartridge side 142, on one end of which, facing the push rods, a push tooth 149 is arranged, see FIG. 12. From FIG. 11 it can be seen that the pusher tooth holder 148 is designed as a dovetail spring which runs in a corresponding dovetail groove 150. Each pusher tooth holder 148 has a non-continuous bore 151 in which a compression spring 152 is arranged in order to press the pusher tooth into the teeth 130 of the push rod.
  • the spring is supported on one side at the end of the bore 151 and on the other side on a cover plate 153 which is fastened in the sides 143 of the thrust member by means of a screw 154.
  • the height of the pusher holder is less than the distance between the plate and the end of the pusher tooth to ensure that the pusher tooth holder slides up and down.
  • the pusher tooth holder does not have to be dovetail-shaped and can have any other shape that can be anchored in the pusher element, such as a T-shaped or rounded shape.
  • the hand-held device 155 described in FIGS. 14-17 is a preferred exemplary embodiment of a discharge device which has a simple structure and is economical to manufacture and yet works precisely.

  • the two push rods are connected to one another via a web 161 with an opening 162 for a finger and can expediently be made from a suitable plastic.
  • 14 also shows that the push rod 159a is wider than the push rod 159b.
  • the trigger lever 157 is pivotable about the axis 164 mounted in the two-part housing and has an eye 182 which is movably connected via an axis 165 to two pull tabs 166, which in turn are connected to the thrust member 168 via an axis 167, see FIG. also Fig. 16.
  • the thrust member has two ribs 169 which are guided in corresponding guides 170 in the two housing walls. The ribs and the corresponding guides do not extend over the entire part of the thrust member, but over a certain part at the cartridge-side end of the thrust member and at the rear end of the housing. In this embodiment, the thrust member is pulled from the trigger.
  • the force is alternately transmitted from the trigger to the push rods 159 by two pairs of pawls 171 and 172.
  • 172 are arranged on the thrust member, at one end of which, facing the push rods, a thrust tooth 173 is arranged, see FIG. also Fig. 17.
  • the two jack pairs are in one such a distance from one another that one pusher tooth can engage on the pushrods 159 offset by half a tooth length of the teeth 160.
  • This also means that only one pair of pusher teeth engages on the teeth of the pushrods. This offset arrangement enables an increased fineness in the feed to be achieved.
  • Each pair of pawls is pivotable about an axis 174 and the pawls arranged on both sides of the push rods are connected to one another via a spring 175 in order to engage the push teeth.
  • the release assembly 176 allows the pusher teeth to swing out and thus the pushrods to be retracted.
  • the pusher teeth are connected to each other via a connecting piece 177, the connecting piece projecting beyond the pawl axis in order to be raised by the conical displacement part 178, which can be actuated by means of a push button 180 under spring pressure 179. Since there are two pairs of pawls in the present example, the unlocking arrangement is accordingly configured symmetrically, so that one push button 180 can drive both connector pairs apart.
  • an extension 183 is arranged on the eye 182 of the trigger, which is acted upon by a leaf spring 184, but the path of which must be limited by a stop 185.
  • the leaf spring 184 is stronger than the return leaf spring 158 and causes a clearance a to arise between the edge 181 and the corresponding part of the trigger, which makes it easier to trigger the pusher teeth.
  • cartridge 4a has a larger diameter than cartridge 4b and accordingly the diameter of the pressure piece 7a is larger than that of pressure piece 7b.
  • the power transmission can take place with other transmission means instead of using axles or bolts on incisions and the like.
