Definitions

  • the present invention relates to a letter opener according to the preamble of claim 1.
  • a wide variety of letter openers are known from the literature, who open an envelope to create a waste strip.
  • Such openers generate waste that has to be disposed of is.
  • the contents of the letter can also be cut be cut up.
  • the opening process is also said to be without that in many known letter openers mostly tedious alignment of the letter to the cutting edge or the tricky insertion of the letter edge into an insertion slot can be started.
  • An object of the invention is also operate the letter opener by hand only can.
  • this preload can be constructively simple and safe working way e.g. by means of spring-loaded Pressure rollers, which act on a shoulder on the circular knife, will be realized. That e.g. with a handle Knife housing can be used without any significant effort move along the rails, the letter to be opened just on the lower rail, which e.g. at the same time as a stop serves, can be freely created from above.
  • the knife carriage can e.g.
  • the letter opener essentially consists of a stationary one Part with the letter support surface 1 and a movable Knife housing (handle) 2.
  • An inclined surface 1 of the opener serves as a support for a letter. This is opened in the simplest way by hand the face 1 placed and slightly down in the direction of arrow A. pressed until its longitudinal edge abuts the stop 4. This stop 4 simultaneously forms a guide rail, on which the round knife 3 with its molded Shoulder 4A can roll along the letter. The guide rail 4 protrudes into the area of the shoulder of the knife molded groove and thus ensures a lateral guidance of the Knife.
  • a second, also connected to the stationary part Guide rail 40 is located opposite surface 1 raised area.
  • the roll on this second rail 40 two pressure rollers 5 from. These two roles 5 are about theirs extended axes of rotation connected with springs 7 on train.
  • the Axes of the rollers 5 are also one in the slots Knife axis receiving component 8 out.
  • the rollers 5 through the upper guide rail 40 on the periphery of the shoulder 4A against the spring action pushed apart, i.e. the two roles are under Preload by the spring 7. In this way Manufacturing tolerances especially in the distance between the two rails 4 and 40 compensated.
  • the lower rail securely into the groove on the shoulder of the Knife pushed in.
  • the cutting edge of the knife is 1-10 Is a hundredth of a millimeter from the contact surface 1, only cuts the knife 3 drawn over the envelope the top paper layer of the envelope. Since the Rail 4 rests on the groove base, the knife can never touch the letter pad.
  • the Knife edge in front of any hard objects in the envelope can have a second one on the side of the knife facing the envelope Shoulder with a slightly smaller diameter than the cutting edge be molded on. Protruding letter content elements (e.g. Paper clips) so raise the other shoulder and with it the Knife edge. Because the knife is in its pre-tensioned Spring back towards the upper rail, In this way, the cutting edge becomes a non-negligible one Part spared.
  • the knife housing move along the rails using handle 2.
  • the handle 2 is hook-shaped Bracket 9 connected to the component 8.
  • FIG. 2 shows, only two elements are visible from the outside: the letter edition and the movable knife housing.
