Definitions

• the invention relates to a cartridge gun with an elongated receiving unit for a cartridge filled with the product to be dispensed, with a metering unit for the product to be dispensed and with a handle which extends in the operating position transversely or obliquely to the elongated receiving unit to the outside.
• Such known cartridge pistols are used for pressing out viscous masses, e.g. B. jointing compounds used from cartridges.
• Known cartridge 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 are dispensed in a metered manner from the opening which lies opposite the displaceable bottom.
• a movable, generally pivotable operating element is connected to the handle and cooperates with the piston rod. By manually pressing this operating element, the piston rod and thus the piston are 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 outwards through this generally nozzle-like opening.
• a disadvantage of the known cartridge guns is the space required. Although the piston rod can be inserted into the receiving unit, the handle, which extends transversely or obliquely to the elongated receiving unit, requires a relatively large amount of space. The space requirement leads to increased transport, packaging and storage costs for the manufacturer and supplier. The space requirement in the sales room is also high. Finally, the user also needs a relatively large space for storing the unused cartridge gun.
• the invention is therefore based on the object of significantly reducing the space required for an unused cartridge gun of the type mentioned.
• the handle In the rest position, the handle therefore requires considerably less space than in the operating position, so that the cartridge pistol requires considerably less space during transport, packaging and storage, as well as during presentation in the sales room.
• the handle is detachably connected to the remaining parts of the cartridge gun. So that loss of individual parts of the cartridge gun is avoided and the user-friendliness is increased, it is proposed, however, that the handle be pivotally connected to the receiving and / or dosing unit. If the metering unit has a displaceable piston, it is also proposed that the handle be pivotable about a pivot axis running transversely to the stroke direction of the piston.
• the handle can be locked in a further advantageous embodiment of the invention, at least in the operating position. If the receiving unit has a holder for receiving the dosing unit, it is furthermore advantageous if the handle has snap connection parts which interact with the holder, so that the handle can be locked and unlocked in a simple manner.
• the snap connection parts have two articulated arms. These articulated arms are preferably located on the handle in the region of the pivot axis.
• the handle can be locked both in the operating position and in the rest position.
• the cartridge pistol can also be handled particularly easily in the rest position of the handle.
• the holder has snap-in connection parts which interact with the free end of the handle. These can be provided, for example, in the form of a projecting tab, behind which the end of the handle can snap into place. In this way, no additional parts on the handle are required for the snap connection.
• the metering unit has a braking device which interacts with the piston, so that a cartridge gun with good metering properties that is simple from a design point of view is obtained.
• the braking device essentially holds the piston rod in position during the pressing-out process when the operating lever is released in order to press again. Process to begin.
• the brake device allows the piston rod to retreat slightly when the work is interrupted, in order to relieve the pressure on the cartridge piston and in this way prevent it from running on.
• the known complicated locking mechanisms can therefore be dispensed with, since the pistol automatically relaxes when work is interrupted.
• the braking device preferably consists of a part of the holder which at least partially closely surrounds the piston rod.
• FIG. 1 shows a partially broken perspective view of a cartridge pistol according to the invention with the handle in the rest position
• FIG. 2 shows the cartridge gun according to FIG. 1 with the handle in the extended operating position
• FIG. 3 shows the connection between the handle and the other parts of the
• FIG. 4 shows a section along the line IV-IV in FIG. 3,
• FIG. 5 shows a section along the line V-V in FIG. 3,
• FIG. 6 shows a partially broken perspective view of the cartridge pistol in a sales packaging, the handle being in the rest position, together with a cartridge
• FIG. 7 shows a packaged cartridge pistol according to FIG. 6, but without a packaged cartridge
• FIG. 8 shows a longitudinal section through a further embodiment.
• the cartridge gun 1 shown in the figures has a receiving unit 2 for receiving a cartridge, a dosing unit 3 and a handle 4 connected to the receiving unit 2 and the dosing unit 3, which can be folded from the rest position in FIG. 1 into the operating position according to FIG. 2 .
• the product to be dispensed e.g. B. the joint sealant is located in a cylindrical cartridge 10 with a movable bottom, which is opposite the cartridge opening ( Figure 6).
• the receiving unit 2 has a holder 5 with an annular front 6, two carriers 7 and a housing 8 on the rear for receiving the dosing unit 3.
• the holder 5 encloses a space 9 for receiving the cartridge 10.
• the metering unit 3 has a piston 11 which is attached to the end of a piston rod 12 which is displaceably mounted in the housing 8.
• a driving disk 13 which can be tilted in a manner known per se (FIG. 5), through the opening 14 of which the piston rod 12 projects.
• the opening 14 is slightly larger than the diameter of the piston rod 12, so that the drive plate 13 is freely displaceable along the piston rod 12.
• the drive plate 13 is pressed backwards by a compression spring 15.
• the handle 4 has an operating element 16, which acts on the underside of the drive plate 13.
• This operating element 16 is part of an operating lever 17 which can be pivoted about an axis 18 and which is actuated by a torsion spring 19 is held in a rest position.
• the drive plate 13 By actuating the operating lever 17 and the forward movement of the operating element 16, the drive plate 13 is initially tilted forward until it presses against the piston rod 12 and is tilted there, and then pushed further forward against the biasing force of the compression spring 15, thereby moving the piston rod 12 with the piston 11 moved forward.
• a braking device 20 in the housing 8 which consists of a the piston rod 12 seated clamping plate and has an opening 21, the diameter of which corresponds to the diameter of the piston rod 12.
• the braking device 20 thereby exerts a frictional force on the piston rod 12 at all times.
• the frictional force is so low that it can be overcome without difficulty when the operating lever 17 is actuated and the piston rod 12 is pushed forward.
• the frictional force is at least as great as the force exerted on the piston 11 by the movable cartridge base, so that the piston 11 with the piston rod 12 does not move backwards when the operating lever 17 is released.
• the cartridge pistol can be packaged and stored in a simple and problem-free manner, since the handle 4 can be moved between a rest position and an operating position.
• the handle 4 can be folded.
• the handle 4 can be pivoted about the same axis 18 as the operating lever 17.
• the pivot axis 18, which runs transversely to the stroke direction of the piston 11, is mounted in downwardly extending extensions 22 of the housing 8 (FIG. 5).
• the handle 4 In the rest position ( Figure 1), the handle 4 is therefore arranged next to and parallel to the elongated bracket 5.
• the handle 4 can be locked both in the rest position and in the operating position.
• a locking tab 23 on the underside of the holder 5 (FIGS. 1 and 3) is used for locking in the rest position, the free end 24 of the handle 4 engaging behind this tab 23.
• snap connection parts are used, which are located on the top of the handle 4 (FIGS. 3 and 4).
• the snap connection parts consist of two articulated arms 25, the ends 26 of which are hook-shaped.
• the articulated arms 25 are made in one piece with the handle 4 from an elastic and flexible material, so that they are "articulated".
• the hook-shaped ends 26 protrude through openings 27 in the rear wall of the housing 8, where they hook behind cams 28.
• the free ends 29 of the articulated arms 25 are pressed together in the direction of arrow P (FIGS. 3 and 4), so that the hook-shaped ends 26 move apart and thereby detach from the cams 28.
• FIG. 7 shows a schematic representation of some further advantageous details of a further embodiment of the cartridge gun according to the invention. For the sake of clarity, some parts such as the compression spring 15 and the drive plate 13 are omitted in this drawing.
• the clamping ring 20 is arranged further forward. It not only serves as a braking device, but in operation also wipes off the abrasion caused by the notching of the drive plate 13 in the piston rod 12.
• an oil-soaked ring 33 is provided on the piston rod 12, which ensures a thin oil film on the piston rod 12 during operation.
• the piston rod 12 is cleaned in this way. On the other hand, it is protected against corrosion during storage or operation in a damp environment. Due to the constant notching of the driving disk 13 in the piston rod 12, which is usually made of iron / steel, the latter is very susceptible to corrosion or oxidation in a moist environment.
• an opening 34 is provided on the upper side of the housing 8, into which an unused closure cap 35 of the cartridge or an unused outlet nozzle of the cartridge can be inserted so that the user does not lose it.
• the handle could not only be pivoted, but also be movably connected to the holder in another way.
• the handle could also be pivotable in a different direction than in the previous example.
• the handle could even be detachably connected to the rest of the cartridge gun.
