Definitions

  • the invention relates to a manual squeezing device for pasty masses, which has a receiving device for a container containing the pasty mass, at least one squeezing piston arranged on a piston rod that is axially displaceable relative to the receiving device, and a handle part equipped with a shifting mechanism, the shifting mechanism comprising a manually operated transport lever, which is pivotable about an axis and is equipped at its end facing a driver for the piston rod with a roller or roller which is in contact with the driver and has an axis of rotation which runs parallel to the pivot axis of the transport lever and at a distance therefrom area of the transport lever projecting beyond the pivot axis.
  • the squeezing devices have a receiving device for a container containing the pasty mass.
  • the container can be, for example, a cartridge with an axially displaceable base, which is inserted into a correspondingly shaped receiving device.
  • the pasty mass can also be present as a sausage-like container in a tubular bag, which is introduced into a tubular receiving cylinder for pressing.
  • the devices are equipped with a squeeze-out piston, which is seated on a piston rod that is axially displaceable relative to the receiving device. When the piston rod is axially displaced, the piston is pressed against the displaceable bottom of the cartridge or against the rear end region of the sausage-like container in the receiving cylinder and the pasty mass is administered through an application opening at the opposite end.
  • the axial displacement of the piston rod takes place, for example, via a driver which is actuated by a transport lever which is pivotably mounted in the handle part of the dispenser.
  • the pressure exerted by the user on the transport lever is transmitted to the driver via the lever area of the transport lever located above the pivot axis.
  • the driver tilts the vertical.
  • the driver tilts on the piston rod that is guided through a bore and takes it with it when it moves forward.
  • the driver aligns itself again vertically, which means that it can slide along the piston rod again without hindrance. With the help of a spring tensioned when advancing the driver, it is moved back into its starting position.
  • DE-U-78 31 594 proposes facing the driver To arrange a roller or roller in the end region of the transport lever which is in contact with the driver and has an axis of rotation which runs parallel to the pivot axis of the transport lever and passes through it at a distance therefrom the region of the transport lever which projects beyond the pivot axis.
  • the roller or roller rolls on the driver during the forward movement of the driver and the piston rod. This reduces the friction and the required squeezing forces are reduced.
  • the masses can have completely different viscosities.
  • a foam to be pressed has a different viscosity than a mortar or a sealing compound.
  • the viscosities of the pasty masses are temperature-dependent. With one and the same mass, completely different extrusion forces are required depending on the ambient temperature. Therefore, while with the known squeezing devices, a certain pasty mass can be squeezed out easily and essentially without great effort at summer temperatures, the same work at lower temperatures, for example in winter, leads to premature fatigue of the user's hand / arm system.
  • the object of the present invention is therefore to improve a manual pressing device to the effect that the effort required when pressing pasty masses can be kept low regardless of their viscosity.
  • a manual squeezing device is to be created which, when used, can minimize the fatigue of the hand / arm system.
  • the invention creates a manual squeezing device for pasty masses, which has a receiving device for a container holding the pasty mass, a squeezing piston arranged on a piston rod axially displaceable relative to the receiving device, and a handle part equipped with a shifting mechanism.
  • the displacement mechanism comprises a manually operable transport lever which is pivotable about an axis and is equipped at its end facing a driver for the piston rod with a roller or roller which is in contact with the driver and has an axis of rotation which is parallel to the pivot axis of the transport lever runs and at a distance from it passes through the region of the transport lever which projects beyond the pivot axis.
  • the distance of the axis of rotation of the roller or roller from the pivot axis of the transport lever can be adjusted with the aid of adjusting means.
  • the force transmission can be increased or decreased depending on the prevailing conditions by the user of the dispenser. Due to the adjustability of the force transmission, the stress on the hand / arm system of the user of the dispenser can be kept low. Depending on the viscosity of the pasty mass to be pressed out, the user can choose a larger or a smaller force transmission.
  • the stroke length for the driver and thus for the piston rod is determined by the distance between the axis of rotation and the pivot axis. Depending on the need, the user can adjust this distance using the adjustment means and thus influence the stroke length.
  • the adjustment means are arranged on the handle. In this way, they are easily accessible to the user and the distance of the axis of rotation of the roller or roller from the pivot axis of the transport lever can be easily adjusted.
  • the adjusting means cooperate with the pivot axis of the transport lever, which is designed as an eccentric.
  • the eccentric By turning the eccentric, the length of the region of the transport lever projecting beyond the swivel axis can be adjusted. The distance of the axis of rotation from the swivel axis and thus the power transmission is also changed.
  • the adjusting means provided on the handle part interact with the axis of rotation of the roller or roller, which is designed as an eccentric.
  • the eccentric By turning the eccentric, the position of the axis of rotation can be adjusted relative to the pivot axis, and the distance between the axis of rotation and the pivot axis is changed.
  • a lever is provided on the outside of the handle part, which lever cooperates with a linkage which is arranged within the handle part.
  • the linkage is connected to the axis of rotation of the roller or roller in such a way that a height adjustment of the linkage results in a distance adjustment of the axis of rotation from the pivot axis.
  • the axis of rotation of the roller or roller at the region of the transport lever projecting beyond the pivot axis is infinitely adjustable in height.
  • the distance between the axis of rotation of the roller or roller and the pivot axis of the transport lever can be changed continuously and thus the power transmission can be adjusted continuously.
  • the extrusion device can be adapted in a particularly advantageous manner to the viscosity of the pasty mass to be pressed out or to the condition of the user's hand / arm system.
  • the axis of rotation of the roller or roller is mounted in a bushing which passes through the region of the transport lever which projects beyond the pivot axis and is height-adjustable by means of an adjusting screw.
  • the adjusting screw interacts via a bevel gear with an adjusting wheel arranged on the handle part.
  • the direction of rotation for larger or smaller force ratios is indicated on the adjustment wheel.
  • the adjusting means comprise a lever arranged on the handle part or an adjusting wheel and a display device for the stroke adjustment. In this way, the user can visually check the set power transmission and thus the set distance between the axis of rotation and the swivel axis.
  • the pressing device 1 comprises a handle part 2 and a receiving device 3 for a container (not shown) containing the pasty mass.
  • the receiving device 3 can be designed as an elongated half-shell, into which, for example, a cartridge can be inserted in such a way that its axially displaceable base bears against an ejection piston 14 which is seated on an axially displaceable piston rod 13.
  • the receiving device 3 can also be designed as a cylindrical tube into which, for example, a sausage-shaped tubular bag with the pasty mass is inserted. The cylindrical tube is open towards the handle part and is designed to receive and guide the squeezing piston 14.
  • the receiving device 3 can also be designed to receive multicomponent masses.
  • two cylindrical tubes can be provided, each of which can hold a tubular bag and each hold and guide an ejection piston.
  • the receiving device can also be designed to receive two or even several cartridges, each of which is assigned an ejection piston. It goes without saying that in this case the axial displacement of the squeezing pistons is coupled.
  • An application nozzle 15 for the pasty mass is provided on the front end 4 of the receiving device 3 facing away from the handle part 2. This can be connected to the cartridge, but it can also be screwed directly onto the front end 4 of the receiving device, in particular in the case of multicomponent compositions.
  • the application nozzle is then a mixing nozzle having a static mixer.
  • the manual squeezing device 1 has a displacement mechanism which is arranged essentially within the handle part 2 and comprises a transport lever 5 articulated on the handle part. The one exerted by the user on the transport lever 5 Pressure is transmitted to the squeezing piston through the components of the displacement mechanism arranged inside the handle part 2.
  • the manual squeezer corresponds to the squeeze-out devices of the applicant, which are described, for example, in the applicant's product catalog "Products and Applications 1995", section 4, pages 52-62 or section 7, page 24.
  • adjusting means 6 are provided on the handle part 2, which allow the stroke length of the squeezing piston to be adjusted.
  • the adjusting means comprise a lever 7 arranged on the outside of the handle part 2.
  • a display device 8 which interacts with the lever 7 allows the user to control the set stroke.
  • FIG. 2 shows a sectional illustration of the handle part 2 with a displacement mechanism of a first exemplary embodiment of the manual squeezing device 1 according to the invention.
  • the transport lever 5 can be pivoted about an axis S which passes through the handle 21 of the handle part 2.
  • the region 51 which projects beyond the pivot axis S of the transport lever has a roller 10 or roller at its end which cooperates with a driver 9 for a piston rod 13 and is in permanent contact with the driver 9.
  • the roller can be rotated about an axis D which runs parallel to the pivot axis S and is arranged at a distance from it in the region 51 of the transport lever 5 which projects beyond the pivot axis S.
  • the distance of the axis of rotation D of the roller 10 from the pivot axis S determines the stroke length of the piston rod 13 axially advanced by the driver 9.
  • the piston rod 13 is guided through a bore 91 in the driver 9.
  • the roller 10 is pressed against the driver, which thereby tilts relative to the vertical orientation.
  • the piston rod 13 is tilted in the bore 91 and is carried along when the driver 9 is moved axially. If the transport lever 5 is released, the spring 11 pushes the driver back into the vertical position.
  • the driver is pushed back into the starting position, whereby it slides freely over the piston rod 13.
  • a stop 12 holds the driver 9 in the starting position.
  • a non-return lock (not shown) for the piston rod 13 is provided in a known manner.
  • the adjusting means 6 comprise an adjusting wheel 7, which is arranged on the outside of the handle 21.
  • an adjusting lever can also be provided.
  • the adjusting wheel 7 is connected to the pivot axis S of the transport lever 5, on which an eccentric 71 is seated. By turning the eccentric 71, the length of the region 51 of the transport lever 5 projecting beyond the pivot axis S and thus the distance a of the axis of rotation D of the roller 10 from the pivot axis S of the transport lever can be adjusted.
  • FIG. 3 shows the eccentric 71 arranged on the pivot axis S in the one end position in which the distance a between the axis of rotation D and the pivot axis S is the smallest.
  • Fig. 4 shows the eccentric in the second end position, in which the distance a is greatest.
  • FIG. 5 of a handle part 2 of the squeezing device 1 largely corresponds to the handle part shown in FIG. 2.
  • the adjusting means 6 interact with the axis of rotation D of the roller 10.
  • the axis of rotation D is connected to an adjusting wheel 7 or adjusting lever provided on the outside of the handle 21 and carries an eccentric 72, by means of which the distance a of the axis of rotation D from the pivot axis S can be adjusted.
  • 6 shows the eccentric 72 in the one end position in which the axis of rotation D has the smallest distance from the pivot axis S;
  • Fig. 7 shows the second end position, in which the distance is greatest.
  • the distance of the axis of rotation D of the roller 10 from the pivot axis of the transport handle 5 can be adjusted by adjusting the height of the axis of rotation D.
  • the transport lever has two axially interrupted stub axles 77, 78 which are mounted in the handle 21.
  • the axle stub 78 on the right in FIGS. 9 and 10 is connected at one end to an adjusting wheel 7 which is arranged on the outside of the handle 21.
  • a bevel gear 74 is located at the other end of the stub axle 78.
  • the bevel gear 74 interacts with a second bevel gear 76, which is arranged at the end of an adjusting screw 75.
  • the height of the adjusting screw 75 is fixed in the upper area 51 of the transport lever 5.
  • a bearing bush 79 is adjustable in height, which in an elongated hole 73 is guided in the upper region 51 of the transport lever 5.
  • the set screw 75 is provided with a thread which interacts, for example, with an internal thread in a vertical bore in the bearing bush 79.
  • the bearing bush 79 receives the axis of rotation D of the roller.
  • the adjusting means comprise an adjusting lever 7 arranged on the transport lever 5, which can be actuated from the outside and is connected to the axis D of the roller 10 via a push rod 80.
  • a bearing block 81 receiving the axis of rotation D slides upwards in an elongated hole 82 recessed in the transport lever 5 and thereby increases the distance a of the axis of rotation D of the roller 10 from the pivot axis S. of the transport lever.
  • the force transmission can be increased or decreased depending on the prevailing conditions by the user of the dispenser. Due to the adjustability of the force transmission, the stress on the hand / arm system of the user of the dispenser can be kept low. Depending on the viscosity of the pasty mass to be pressed out, the user can choose a larger or a smaller force transmission.
  • the stroke length for the driver and thus for the piston rod is determined by the distance between the axis of rotation and the pivot axis. Depending on requirements, the user can therefore adjust this distance by means arranged on the handle part and in this way influence the stroke length.
