Definitions

  • the invention relates to a manually operated, electromotive-driven can opener for separating a lid from a can with a knife which can be pivoted about an axis of rotation and which, when disconnected, interacts with a transport wheel rotating about a shaft, with a housing on which a work surface is formed which both the knife and the transport wheel protrude, the axis of rotation of the knife and the axis of rotation of the transport wheel running parallel to one another and an electric motor arranged in the interior of the housing driving the shaft of the transport wheel via a gear.
  • Such a manually operated, electric motor-driven can opener is already known from US Pat. No. 2,883,745.
  • the electric motor runs in the longitudinal direction of the housing (FIG. 3).
  • the alignment of the electric motor in the longitudinal direction of the housing leads to a compact, small-dimensioned hand-held opener.
  • this handheld can opener it is to be regarded as less advantageous that the position of the electric motor relative to the position of the transport wheel necessitates an angular gear, which considerably deteriorates the efficiency of the can opener.
  • This is particularly disadvantageous when the can opener is operated with batteries, for example; because due to the higher energy consumption due to the angular gear, the batteries are discharged in a much shorter period of time. Moving the entire drive unit to the front area of the can opener - i.e. away from the handle - also leads to an uneven weight distribution and thus to an increased holding force of the can opener during the cutting process.
  • the object of the invention is therefore to provide a manually operated, electric motor-driven can opener which has an optimal efficiency compared to comparable hand can openers, which is also user-friendly, small in size and low in manufacturing costs.
  • the transmission is designed as a spur gear, that the drive shaft of the electric motor, the axes of the spur gears of the gear and the shaft of the transport wheel run parallel to each other and that the longitudinal axis of the housing, along which the electric motor, the spur gear and the shaft is arranged, forms an angle (a) with the shaft of the transport wheel which is less than 90 °.
  • the inclination of the drive unit with respect to the longitudinal axis of the can opener essentially depends on the dimensioning of the transmission from the shortest distance (b) between the central axis of the electric motor and the central axis of the shaft of the transport wheel.
  • the dimension (b) is about 65 mm, while the dimension (c) extending in the longitudinal direction of the electric motor, which lies between the end of the electric motor facing away from the transmission and the end of the gear wheel fastened to the shaft of the transport wheel, is about 60 mm .
  • the angle (a) between the longitudinal axis of the housing and the shaft of the transport wheel can be optimally adapted to the housing, depending on the shape of the housing of the hand can opener, and so that the focus falls into the hand area of a user during use of the can opener, it is in one Further development of the invention provides that in the working position of the can opener, the longitudinal axis of the housing parallel to the lid of the can runs and that the housing surrounding the spur gear and the electric motor simultaneously forms the handle of the can opener.
  • the can opener according to the invention can nevertheless be designed to be relatively long without being disruptive to the hand from the can opener Tilting moments must be compensated by this.
  • the housing surrounding the drive unit simultaneously forms the handle of the can opener, elaborate, additionally formed on the housing and therefore costly handles are avoided, so that a particularly easy to manufacture housing shape is created.
  • the housing is cylindrical, preferably circular cylindrical, and when the working surface is formed on the end face of the can opener.
  • the circular cylindrical shape results in particularly simple tools for shaping the housing.
  • the circular-cylindrical design of the housing makes it much easier to handle the can opener, since the outer surface of the housing that comes into contact with the hand is just large enough for good force distribution and therefore good handling of the can opener.
  • cans can be opened particularly user-friendly, since the front of the housing forms the work surface.
  • one side of the bearing of the axles and the shaft of the pinion gear is mounted on a support plate provided with bearing shells
  • the other side of the bearing of the axles and the shaft of the transport wheel is mounted on bearing shells formed on the housing
  • the carrier plate is fastened to the housing in such a way that the corresponding bearing shells are aligned with one another.
  • the carrier plate also prevents bearing points from being required on both housing shells for mounting the drive unit. This means that there is no considerable effort for centering the two housing parts with respect to the drive unit if the drive unit is only stored directly between the two housing shells. Even when the can opener is dismantled, the carrier plate ensures that all the gears remain centered on it and do not fall out of the housing. This is particularly noticeable when not a part of the drive unit, but a completely different one, has to be connected to the drive unit during a repair. component that is not in connection must be replaced.
  • the housing consist of two housing shells divided in the longitudinal direction of the can opener and that the carrier plate be clamped between the two assembled housing shells and is held stationary in this position.
  • a particularly stable and vibration-free fastening and a simple centering of the electric motor on the carrier plate is achieved in that the electric motor is centered on the carrier plate by means of a sleeve encompassing the motor and molded onto the carrier plate and fastened to the carrier plate by means of fastening means.
  • the sleeve can be fastened by means of latching elements formed at its free end to recesses correspondingly formed in the housing shell.
  • the carrier plate also has a connection to the housing to avoid vibrations.
  • the can opener 1 which is guided by hand, consists of an essentially cylindrical housing 2, which consists of two assembled housing shells 3, 4.
  • the two housing shells 3, 4 each form a half shell, which are assembled at their dividing lines 5, 6 (FIG. 2) and which run in the longitudinal direction Z of the can opener 1.
  • 2 runs parallel to the center lines 7, 8 and parallel to the lateral surface 9 of the two housing shells 3, 4.
  • the two housing shells 3, 4 forming a tube and running from bottom to top in FIGS. 1 and 2 are sealed at their lower end in FIGS. 1 and 2 by a cover 10, for example by welding, screwing, clipping or gluing.
  • the cylindrical housing 2 is chamfered in the upper area on the end face.
  • This bevel forms the working surface 11 of the can opener 1.
  • the working surface 11 forms an angle d of 30 ° with the center line 7.
  • the working surface 11 begins approximately according to 2/3 to 3/4 length of the can opener 1 on the outer surface 9 of the housing 2 and extends up to approximately the middle of the cover plate 12 which delimits the can opener 1 from above and runs horizontally according to FIG the flat, oblique section through the cylindrical housing 2, the curve of the outer contour 82 of the working surface 11 describes a parabola.
  • the cover plate 12 is connected in one piece to the work surface 11 and the housing shell 4.
  • a stepped bore 13 formed in the cover plate 12 according to FIG. 2 serves to fasten the two housing shells 3, 4 in the upper region by means of a screw 14 which is screwed into a base 15 connected to the housing shell 3.
  • the cutting device formed by a knife 16 and a transport wheel 17 protrudes from the working surface 11. Furthermore, according to FIG. 1, on the work surface 11, a stop 19 extends parallel to the center line 8 and, when the can lid 88 is opened, gives a can 77 (shown in dashed lines) a guidance so that the can 77 always maintains a predetermined angle to the knife 16 in order to keep the cutting work as low as possible.
  • the stop 18 lies on the axis of rotation 20 of the transport wheel 17 which runs vertically according to FIG. 1 and serves to ensure that when a can 77 is being put on, it can only be attached to the transport wheel 17 in such a way that the can 77 is transported properly.
  • Saw teeth 21 are evenly distributed on the outer circumference of the transport wheel 17, as shown in FIG. 1, which engage in the lower flanged rim 89 of the can 77 during the cutting process and thus enable the can 77 to rotate in the direction U.
  • the knife 16 is rotatably supported in the direction L about its axis of rotation 22 toward the transport wheel 17 or away from the transport wheel 17. 1, approximately the center line 8 represents the area in which the can lid 88 of a can 77 is located during the cutting process, the can lid 88 then running essentially parallel to the center line 8 and perpendicularly from the imaging plane according to FIG. 1 (the inclined position the can of 19 or 18 was neglected).
  • the knife 16 has a piercing tip 23 and a cutting edge 24 which adjoins at an angle upwards.
  • a third stop 25 formed on the knife 16 ensures that during the cutting process the knife 16 is supported on the flanged edge 89 of a can 77 and therefore not deeper into the can lid 88 penetrates than is absolutely necessary.
  • the third stop 25 also serves to transmit the pressing force directed onto a can 77 during the cutting process via the flanged edge 89 to the transport wheel 17 in order to achieve a rotation of the can 77 - which should also be uniform.
  • a fourth stop 26 formed in the form of a pin protrudes on the working surface 11, which prevents the can 77 from getting stuck - And cutting process around the contact point 27 formed between the can 77 and the transport wheel 17 according to FIG. 1 rotates counterclockwise.
  • the fourth stop 26 is firmly connected to the cover plate 12.
  • an actuating button 29 provided with an arrow 28 is formed below the stop 26, which, when actuated in the direction of the arrow 28, enables the knife 16 to be removed from the can opener 1 perpendicular to the work surface 11 from the plane of the drawing, so that the knife 16 For example, it can be replaced by another, sharper knife or, if it is contaminated by food, it can be cleaned.
  • a resilient engagement element is formed on the actuating button 29, which engages radially from the outside in a groove of the axis of rotation 22, which is also not shown, and thus secures the knife 16 against falling out.
  • a switching button 31 protrudes radially from an opening 30 formed on the housing shell 3 and is connected to the knife 16 via a lever mechanism (not shown in the drawing), that when the switch button 31 is actuated in the direction F, the knife 16 is pivoted about the axis of rotation 22 to the transport wheel 17 until the piercing tip 23 rests on the surface of the can lid 88 of a can 77.
  • an elastic spring element (not shown) formed in the transmission path between the switch button 31 and the axis of rotation 22 ensures that the switch button 31 can still be moved without further rotation of the knife 16, to increase the pressure of the piercing tip 23 on the can lid 88 and to actuate an electrical switch (not shown) located in the housing 2, which then switches on the electric motor 32 and thus via the gear 33 (FIG. 3) the transport wheel 17 in rotation U offset.
  • the knife 16 automatically sticks into the can lid 88 and swivels due to the frictional force which results between the can lid 88 and the piercing tip 23 and which is generated by the rotation of the can lid 88 now until the stop 25 rests on the flanged edge 89 from above.
  • a recess 34 is formed on the housing shell 4 in the left area between the work surface 11 and the cover 10, the outer surface 35 of which also extends concentrically with the center line 8.
  • a holder 36 is mounted in the upper region above the knife 16 on the lateral surface 9 of the housing shell 3, on the end of which closer to the working surface 11 a ball 38 is suspended in a spherical cap 37 on which a rotatable sleeve 39 is attached, which connects to the end of the bracket 36 and in the free space of which a magnet 40 is attached.
  • the pivoting direction of the holder 36 is concentric to in FIG Center line 8 of the housing 2 and can be pivoted in the circumferential direction of the housing 2 at least to the center line 8 so that after the can lid 88 has been separated from a can 77, the can lid 77 is held by the magnet 40.
  • the holder 36 prevents the can lid 88 from being immersed in the foodstuff in the can 77 so that the impurities possibly present on the top of the can lid 88 do not come into contact with the food of the can 77.
  • the can opener 1 is also held in a horizontal position by an operator when a can 77 is opened. It is clear that the work surface 11 is perpendicular to the plane of the drawing and that it includes an angle d with the center line 7, which in the embodiment according to FIGS. 1 to 4 is approximately 30 °. This ensures that a long, flat tin, such as a fish tin, which protrudes downward beyond the work surface 11 in accordance with FIG. 2, cannot touch a hand (not shown) which grips the can opener 1.
  • FIG. 4 The longitudinal section shown in FIG. 4 through the can opener 1 according to the cut III-III according to FIG. 3, like FIG. 3, shows the drive unit fastened in the housing 2, which is fastened on a carrier plate 41 and which essentially consists of an electric motor 32 and there is a transmission 33, the transport wheel 17 shown in FIGS. 1 and 2 and 4 being fastened to its output-side shaft 42 by means of a left-handed thread 43.
