Definitions

  • the invention relates to a caulking gun with a receiving unit for a filled with the product to be dispensed cartridge, with a metering unit for the product to be dispensed and with a handle.
  • Such known caulking guns are used for pressing viscous masses, for. As jointing compounds, used from cartridges.
  • Known caulking guns consist of the receiving unit, the dosing unit and a handle firmly connected to the receiving unit.
  • the metering unit has a displaceably mounted piston rod with a piston which presses against the displaceable bottom of an inserted cartridge, so that the contents of the cartridge metered out of the opening, which is opposite to the displaceable bottom.
  • a movable, generally pivotable control element is connected, which cooperates with the piston rod. By manually pressing on this control element, the piston rod and thus the piston is moved, so that the bottom of the cartridge is pushed towards the metering opening of the cartridge and the contents of the cartridge are pressed through this generally nozzle-like opening to the outside.
  • caulking gun shows the US 6349857 B1 with an elongate receiving unit for receiving a cartridge.
  • a disadvantage of this type of cartridge guns is associated with the design footprint. Through the long stretched. Recording unit for the cartridge requires the well-known pistol, especially when not in use, a lot of space. The increased space requirement leads to increased transport, packaging and storage costs for manufacturers and suppliers. Also, the space required in sales rooms is high. Finally, the user also needs a relatively large space to store the unused cartridge gun. Another disadvantage is also due to the design and the space required when working with conventional caulking guns. In a newly inserted cartridge, the displaceably mounted piston rod with the piston, which presses against the displaceable bottom of the inserted cartridge, is relatively far back from the cartridge gun. This can lead to problems when working with the cartridge gun, for example when applying jointing compounds in bathrooms, since the space required for safe and quick application of the jointing compound to the desired surface is often not available.
  • the international patent application WO 2005/097354 A1 shows a caulking gun into which a cartridge is inserted, without an elongated receiving unit is necessary.
  • the above-mentioned disadvantages show the required space. Even if the cartridge is not inserted, the piston rod, which is essentially as long as a cartridge, requires a relatively large amount of space. When the cartridge is inserted, the user faces the problem of the rearwardly protruding piston rod.
  • the US patent US 6961621 B2 shows a caulking gun, wherein two chains are provided in the cartridge, which communicate with an operating element of the handle and serve to discharge viscous masses from a cartridge.
  • the chains are received by guide tunnels mounted on the side of the gun and extending over the entire length of the cartridge gun.
  • This is in the present design is a completely different active system, because no piston rod is used.
  • the disadvantage of this design is also the increased space required, due to the existing elongated receiving unit, which is absolutely necessary for the lateral recordings of the pairs of chains.
  • the object of the present invention is to provide an improved caulking gun, which requires less space in the use and in the non-use state.
  • the basic idea of the invention is to use a caulking gun with a receiving unit for a product to be dispensed with a dispensing unit for dispensing product and with a handle and a displaceable piston rod, wherein the piston rod at least partially on the output side of the dispensed product The opposite side is designed deflectable, wherein the piston rod consists of at least two piston rod elements and wherein the piston rod elements are held together with at least one elastic component and wherein the piston rod elements are at least partially hollow designed to provide a guide the elastic member.
  • the deflection is preferably carried out in the radial direction to the actuating direction of the piston rod in the delivery of the product.
  • This option proves advantageous for deflection, in particular in the case of newly inserted cartridges which are filled with a product to be dispensed.
  • the piston rod projects far out of the rear of the cartridge gun. This requires an increased space requirement when working with the caulking gun, which is often not available in many applications, such as in the product order in corners or behind components, especially in a Silikonverhegung in the sanitary area.
  • the space required can be significantly reduced. In this way, a safe and easy order of the product to be dispensed on the cartridge gun allows.
  • the user can quickly pull out the piston pushed into the cartridge after the product has been applied or for changing the cartridge.
  • Another advantage is the saving of the required storage space through the deflectable piston rod.
  • craftsmen or other users work with several cartridge guns simultaneously, in each of which a cartridge with different products or the same products of different color or quality are inserted.
  • the piston rod With the cartridge inserted, the piston rod, whether of the material in the cartridge would protrude on the rear side of the cartridge gun and, depending on the amount of remaining material in the cartridge, require an increased storage space.
  • the user can store this by deflection of the piston rod in a tool box or a bucket with much less space. It is necessary, even with inserted and filled with the product to be dispensed cartridge for the storage of the gun an insignificantly larger space than for a cartridge itself.
  • the piston rod of the cartridge gun is elastically deflectable.
  • the elasticity ensures an assumption of the initial shape of the piston rod by a relief after a deflection by means of force, in particular by the user or a package.
  • a piston rod is provided, which is designed on the one hand deflectable, on the other hand automatically returns to discharge in the original shape, so it is during the advancement of the piston rod for dispensing the product to be applied to no interference, for example by tilting the piston rod in the dosing.
  • the user can guide the caulking gun even in hard-to-reach work areas with a small space requirement such that the piston rod is deflected by space-reducing components, such as sanitary facilities.
  • the elasticity of the piston rod returns to its original shape without the user actively intervening.
  • the elasticity is provided by the elastic element, it being advantageous if the surface of the piston rod is substantially smooth and the use of the elastic element does not hinder the propulsion of the piston rod during product application.
