Definitions

  • the present invention relates to a manual discharge device for cartridges with a a push rod acting friction brake according to the preamble of claim 1, as well as a brake spring for use as a friction brake in a discharge device for Cartridges.
  • Friction brakes are the primary job after finishing of the feed by relieving the flexible Cartridge-related relief path of the push rod too enable. That means closing the push rod as little as possible hinder, however, during the follow-up stroke by the Feed element caused acting on the push rod To effectively brake towing power. While feeding the push rod or in the case of a two-component cartridge Double push rod due to the engagement of the feed element there is a risk that the Push rod is easily crossed and therefore the clean one No more engagement with the teeth of the feed element is guaranteed.
  • a hand-operated discharge device with Specify friction brake that the above Does not have disadvantages and an inexpensive to produce Contains friction brake, which both the push rod when Follow-up stroke effectively brakes as well as the push rod or in the case of two-component cartridges, the double push rod aligns in such a way that the teeth of the Feed organ perfectly in the toothing of the push rod can intervene.
  • FIGS. 1 and 2 part of the housing 1 shown, which consists essentially of the housing body 2 and the cover 3.
  • the double push rod 4 in the following only push rod named, since it is not essential to the invention whether it is a simple or a double push rod, with the two pusher plates 5 and 6, which are either the same Can have a cross-section or a different one Cross section for cartridges with different volumes or cross-sectional areas.
  • the present Description with "front" the end of the pusher plate and accordingly "rear” means the other end.
  • the push rod 4 shown here has at the rear End a tab 7 to attach it to for replacing the To be able to withdraw the cartridge.
  • the push rod 4 has also a toothing 8, see also Figure 6, in which the a toothing 9 provided pawl 10 of a feed member 11 takes hold.
  • the pivot point 12 can also be seen in FIG. 6 of the feed member and the lever 13 to the feed member to pivot and disengage the teeth and thus allowing the push rod to retract.
  • the spring 20 consists essentially of a loop part 21, which has a radius R, and one thereon subsequent clamping and alignment part, which consists of the two Legs 22 and 23 exist.
  • the one leg 22 is straight, while the other leg 23 is bent or angled, so that the spring as a whole with respect to its longitudinal axis is asymmetrical.
  • the straight leg 22 also has an elongated hole 24 for securing and limiting travel on.
  • This special shape of the spring causes that the push rod, or its web, in the example according to FIG. 1 Bridge 15, always aligned straight and against the two Outer edges 25 and 26 of the rear guide 17 and front guide 19 is pressed.
  • the Shape of the loop part the spring force, apart from Influence of the wall thickness and the material, by the size of radius R precisely.
  • the aligned position according to Figure 1 corresponds to Push rod position of Figure 5A, in which is sketched, that the web 15 of the push rod against the two edges 25 and 26 of the guides 17 and 19 abuts.
  • the spring is on the cover of the housing attached, being on the inside of the Outer wall 27 of the cover rests and between the Inside of the outer wall and one at a distance from it arranged guide web 28 is clamped.
  • the Guide bar is used for the precise alignment of the straight Leg 22 of the brake spring, the two leading edges 25 and 26 and the stop surface facing the outer wall 29 of the guide web lie in one plane.
  • the amount of The guide bar corresponds approximately to the height of paragraph 30 the brake spring, see Figure 3, so that the web 15 under the Guide bar slides through. It goes without saying that the guide web 28 has a slightly smaller thickness than the web 15 to effectively clamp it.
  • Stops for the brake spring which is defined as a free relief route, is denoted by B in Figure 1.
  • B To secure the Brake spring and also to limit the free Relief path is a pin through the outer wall and provided through the elongated hole 24 so that the brake spring secured, but in the longitudinal direction by a certain one Is displaceable.
  • the brake spring according to the invention was based on a Example of a double cartridge described because it is straight there is a particular advantage because the brake spring needs to act only on a web of a push rod to the whole Push rod, d. H. to align the double push rod, it is irrelevant whether the pusher plates of the Push rod cartridges with a ratio of 1: 1 or a different ratio up to a ratio of Squeeze 1:10.
  • the brake spring according to the invention can however also for discharge devices with only one push rod be used.
