Definitions

  • the invention relates to a plier can opener according to the preamble of claim 1.
  • Such pliers can openers are very widespread in the household today and are described, for example, in DE-U-76 13 201.
  • a disadvantage of these devices is that after the pliers can opener has been attached to the can to be opened when used as intended, a relatively large force must be constantly applied to the handles in order to keep the cutting wheel or the cutting knife in engagement.
  • DE-C-253 607 a device for the automatic, non-positive coupling of the two pliers elements.
  • This device consists of a horn formed on one pliers element with a sawtooth profile provided on one side and a spring-loaded, one-armed retaining hook which is pivotably mounted on the other pliers element. This eliminates the need for a forceful locking of the two pliers elements during the opening process.
  • a disadvantage of this design is that the individual components are exposed and represent a permanent risk of pinching skin areas when used as intended.
  • the handling is also very awkward. Just when the can is open, that is to say the lid has been cut open, the one-armed lever must be pushed back with the second hand to enable the two pliers elements to be released; at this critical moment the can cannot be held.
  • the object of the invention is to improve the plier can opener known from DE-C-253 607 in such a way that the can is opened without the risk of pinching skin areas and the pliers elements can be released with only one hand.
  • the swiveling holding element at the transition between the handle and work area makes it particularly easy to use.
  • the recessed arrangement of the holding element makes it impossible to pinch areas of skin.
  • the holding element engages automatically due to the appropriate design. After completing the process, it can be opened easily with a thumb movement due to the convenient arrangement.
  • the device looks clean due to the largely recessed arrangement of the holding element and offers only a small contact surface for dirt.
  • FIG. 1 to 3 the pliers can opener is shown fully assembled in three views.
  • An upper tong element 1 and a lower tong element 2 are movably connected to one another via a joint 3.
  • the pliers elements 1, 2 each consist of a work area 4 and a handle area 5.
  • the cutting and drive elements 6 are mounted in the work area 4.
  • the grip areas 5 accommodate the handles 7 and 8.
  • Both pliers elements 1, 2 have in common that they are provided with a stepped shoulder 9 between the working area 4 and the handle area 5, the height 10 of which corresponds to the wall thickness 11 of the handles 7, 8.
  • both pliers elements 1, 2 have in common that they have approximately a U-shaped cross section according to FIG. 10 in the grip area.
  • the upper pliers element 1 is recessed in connection to the work area 4 for receiving a swivel handle holding element 12 to about half the thickness of the handle area.
  • the swivel handle holding element 12 is rotatably mounted on an axle stub 13 and is pressed against the working area 4 by a compression spring 14.
  • the compression spring 14 is held in the pliers element 1 in a spring groove 15 which continues in a bore 16 in the swivel handle holding element 12.
  • the swivel handle holding element ment 12 is provided with a corrugation 17 in the grip area and is axially secured by a stop 18.
  • the swivel handle holding element 12 engages via its holding hook 19 in a receptacle 20 of the lower pliers element 2.
  • the receptacle 20 also halves the cross-sectional thickness of the lower pliers element 2 to approximately half. However, with the lower pliers element, the lower web 21 is retained in full.
  • the receptacle 20 is delimited by an inclined holding web 22. With its one surface, this holding web 22 forms the run-on slope 23 for the holding hook 19 and has the same height as the upper web 24.
  • the spring channel 15 and the receptacle 20 are covered by the handles 7 and 8, which are pushed onto the handle areas 5.
  • the handle 8 is recessed on the side of the swivel handle holding element 12 on the side 25 and in the passage area of the holding hook 19.
  • the handle 7 is recessed only in the passage area of the holding hook.
  • the recess 26 lies only in the region of the passage of the holding hook 19 and ends at the start of the run-on slope 23.
  • the recess 26 has approximately the width 27 of the receptacle 20.
  • the holding hook 19 is therefore tapered relative to the swivel handle area 28.
  • the pivoted handle region 28 is approximately flush with the side wall 29 of the handle 8 in the assembled state.
  • the pliers elements 1, 2 are each provided with an elongated incision 30, 31 for a leg spring 32.
  • the one incision 30 is provided with a smooth insertion bevel 33 and the other incision 31 is provided with a holding shoulder 34 which prevents the leg spring 32 from slipping back.
  • the leg spring 32 exerts a force in the direction of opening the pliers elements 1, 2.
  • the swivel handle holding element 12 is first pivoted in the direction of arrow 35 against the force of the compression spring 14. As a result, the retaining hook 19 is released from the retaining web 22; the two pliers elements 1, 2 are opened by the action of the leg spring 32 according to the arrows 36.
  • the pliers can opener is then placed in a known manner on a can to be opened and the cutting and drive elements 6 are brought into engagement by pressing the handles 7 and 8 together.
  • the holding hook 19 is deflected on the run-up slope 23 and hooked onto the holding web 22, as shown in FIG. 1.
  • the two pliers elements 1, 2 are securely locked.
