Definitions

  • the invention relates to a plier-like device for opening screw caps according to the preamble of claim 1.
  • Screw cap openers are used in practically every household under the term screw cap opener.
  • a very well-known device is described in DE-GM 75 14 833. Only when using the device to open a small bottle screw cap are the two handles ergonomically close enough. In contrast, the ratio deteriorates drastically with large screw lids, such as jam jars. A woman with small hands is practically no longer able to open a glass on her own.
  • the object of the invention is to provide a screw cap opener which can be used for both large and small screw caps with the same grip position and the same force application, which is ergonomically correct and can be used by both left and right-handers and which has a high clamping force on the Can exercise screw cap.
  • the flat pull rod enables stepless adjustment to any screw cap size.
  • the adjustment path of the operating handle is small, so that the ergonomically optimal hand position can always be used. Due to the short adjustment path, it doesn't matter whether the device is operated with the left or right hand.
  • the push handle guided in a guide slot in the handle, makes it particularly easy to adjust the pull rod with a clamp.
  • the spacer nose prevents parts of the device from being bent or destroyed when the device is actuated with the drawbar fully inserted.
  • the U-shaped design of the actuating handle makes handling particularly pleasant.
  • the right-angled arrangement of the clamping claws to the holding claws enables safe clamping of both small and large screw caps. Due to the angular design of the drawbar, a reliable anti-rotation lock is achieved.
  • An operating handle 1 is pivotable about a bearing 2 in the handle 3.
  • the adjustment path 4 of the operating handle 1 is limited by a stop 5 in the operating handle 1.
  • the actuating handle 1 is U-shaped and overlaps the handle 3 when adjusting.
  • the handle 1 While the operating handle 1 consists of a one-piece shell, the handle is composed of a lower part 6 and an upper part 7. The lower part 6 and the upper part 7 are locked by mushroom heads 8. The upper and lower part form a guide channel 10 for a pull rod 11 by means of webs 9. A clamping bracket 13 with rents 14 is fastened to the pull rod 11 at the front end 12. The clamping bracket 13 is designed as a die-cast part. At the other end 15 of the pull rod 11, a push handle 16 is attached. The push handle consists of a holding pin 17 and a thumb plate 18. The handle 7 is provided with a guide groove 19 for the thumb plate 18 and a guide slot 20 for the holding pin 17.
  • a guide wall 22 and a counter wall 23 are formed perpendicularly to the guide channel 10 in the front region 21 of the handle 3.
  • Guide wall 22 and counter wall 23 are of course divided into the lower part 6 and upper part 7 in accordance with the division of the handle 3.
  • On the guide wall 22 is a pull plate 11 penetrated by a spring 25 loaded tension plate 24 flat.
  • the spring 25 is supported on the counter wall 23.
  • the tension plate 24 is extended on one side by an application area 26 which bears against a pressure rib 27 of the actuating handle 1.
  • the pressure rib 27 and the guide wall 22 lie in the same position in the neutral position shown in FIG.
  • the front region 21 of the handle 3 ends in its lower part 6 in a receiving head 28 for holding claws 29.
  • the holding claws 29 consist of a sheet metal part 30 whose ends 31 are bent inwards.
  • the clamping bracket 13 is provided with three clamping claws 32 and 33 arranged approximately in a circle.
  • the corners of the holding claws 29 form an equilateral triangle with the tip of the central clamping claw 33 in the small position shown in FIG.
  • a spacer nose 34 is provided on the clamping bracket 13, which in the small position shown just abuts against the pull plate 24. If the clamp 13 is now pushed in further, the tension plate is pressed inward against the force of the spring 25, so that when the actuating handle 1 is actuated, the pressure rib 27 runs into space.
  • the pressure rib 27 is first used for the Actuation area 26 of the tension plate 24 is slightly inclined against the spring 25 until compensation for the play in the bore 36. As soon as the game is balanced, the tension plate 24 is jammed with the tension rod 11 and moves it in the direction 37. A cover lying between the clamping claws 32, 33 and the holding claws 29 is firmly clamped.
  • the push handle 16 When using larger screw caps, the push handle 16 is moved in the direction 38 until the cover can be easily inserted between the clamping claws 32, 33 and the holding claws 29. The process is then repeated as already described. Due to the position of the operating handle 1, a sensible operation is achieved. Just an attempt to turn is enough to swivel the operating handle in the direction of 35 and thus in the direction of the clamps.
  • a suspension eye 39 is provided on the handle 3 for easy access.
  • a retaining knob 40 is provided on the clamping bracket 13, which snaps behind a cladding area 41 of the actuating handle 1.
  • FIG. 1 A further position of the clamping bracket for a larger screw cap is shown in dash-dot lines in FIG.
