Definitions

  • the invention relates to a device according to the precharacterizing portion of claim 1.
  • the cylinder sector shaped articles are in practice constituted of parts of food products.
  • the food products in question are cylinder shaped and may for example be constituted of cakes, cheese etc.
  • the parts obtain the cylinder sector shape when cut out from the food products since such technique of cutting out in general causes the most rational division of the food products into smaller parts.
  • DE-utility model patent 8 019 402 there is disclosed a cutting and grasping device having gripping members formed by eyes. Such a design of the gripping members falls outside the scope of the precharacterizing portion of claim 1 and makes it very difficult to efficiently operate the device for cutting, in particular when stiffer cakes are in question, since the user has to operate the device with one hand, namely with the thumb in one eye and the index finger or middle finger in the other eye. Also this known device will most certainly have to be supplemented with a conventional cake slice for handling low or soft cakes.
  • the object of the invention is to reduce the above defined draw backs and to achieve a device with a, as far as possible, universal utility for all kinds of cakes or other food products.
  • the device according to the invention can be brought in a position where its both blade parts can function as one single cutting blade at the same time as the gripping members form a single elongated rodlike grip, around which one hand may grasp, the device can on one hand be used in a way similar to a conventional cake slice, and on the other hand for grasping the article in question between the two blade parts.
  • the device can on one hand be used in a way similar to a conventional cake slice, and on the other hand for grasping the article in question between the two blade parts.
  • the device according to the invention will below be described as especially intended for grasping and handling substantially cylinder sector shaped articles in form of pieces of cake.
  • the device comprises two blade parts 1, 2 and a grip located at one end thereof generally denoted with 3.
  • the two blade parts 1 and 2 are pivotally connected to each other by means of a hinge 4 located at that end of the blade parts 1, 2 which is opposite to the grip 3.
  • the grip 3 and the hinge 4 are in the exemplified embodiment located at diametrically opposite ends of the device, which here is illustrated as relatively elongated, but which in practice could be substantially shorter and wider.
  • the blade parts 1 and 2 are pivotable about the hinge 4 in a direction towards each other to a position (fig. 1) where they lie close to each other or against each other in a substantially parallel condition.
  • fig. 1 the intention is that the blade parts 1 and 2 in this position shall form a totally flat and relatively thin disc like structure.
  • the blade parts 1 and 2 comprise bends 5 in the vicinity of the grip but these are intended to be located outwardly of the portions of the blade parts 1, 2 which normally come into contact with pieces of cake.
  • the hinge 4 is intended to form a geometric pivot axis which extends substantially perpendicularly to the longitudinal direction of the device and parallel with the plane of the blade parts 1, 2.
  • Portions 20 which are extending obliquely from the bends 5 in a direction towards the gripping members of the blade parts are located in close vicinity to each other in a parallel condition when the blade parts are pivoted towards each other.
  • the blade parts 1, 2 is designed with a cutting edge 7 along at least one edge (see the edge 6 in fig. 2), said cutting edge may possibly be cogged. It is then meant that the cutting edges 7 on the two blade parts 1 and 2 are so designed that the cutting edges cooperate for forming one single main cutting edge, when the two blade parts 1 and 2 are pivoted towards each other.
  • the device thus can in a conventional way be used for cutting for instance a piece of cake out of a cake.
  • the grip is in the example formed by two gripping members 8, 9, one of which is arranged on the blade part 1 while the other 9 is arranged on the blade part 2.
  • the gripping members 8 and 9 are each separately operable as a grip when the blade parts 1 and 2 are pivoted away from each other (fig. 8).
  • the gripping members 8 and 9 are so designed that they jointly form one single grip 3, which can be grasped by one hand when the blade parts 1, 2 are pivoted towards each other to the position according to fig. 1 and 2.
  • the surfaces 10 of the gripping members 8 and 9, which are facing towards each other can in practice be flat to enable a close application against each other analogically to the way in which the blade parts 1 and 2 are applicable against each other.
  • the device presents means 11 for holding together the blade parts 1 and 2 in their condition pivoted towards each other.
  • Said holding means could be arranged to operate on basis of magnetism.
  • the holding means could be designed to operate by mechanical engagement.
  • Such mechanical holding means could as an example consist of snap locking means releasable by actuation of a certain force in a direction away from each other or locking means releasable by loosening of a form locking connection. It is suitable to arrange the holding means 11 in the area of the grip 3, preferably so that one means is arranged on each of the gripping members 8 and 9 so that these two means enter into a co-operation holding the gripping members together when they are moved towards each other.
  • the blade parts 1 and 2 are lying relatively close to each other in the folded condition according to fig. 1, it is recommendable to design the blade parts 1 and 2 in such a way that they, apart from the area of the hinge 4, not really are deformed during normal use of the device.
  • the flat shape of the blade parts 1 and 2 shall thus as far as possible be maintained.
  • This material portion 12 should then allow pivoting of the blade parts 1 and 2 towards and away from each other by elastic deformation of the material in the portion 12. It is then preferred that the blade parts 1 and 2 are manufactured in one single material piece and that the flexible material piece 12 forms a transition between the blade parts 1 and 2. The material portion 12 will thereby form a diversion of substantially 180 degrees of the material piece which forms the blade parts 1 and 2. The arrangement can then be such that the elasticity of the material portion 12 tends to actuate the blade parts 1 and 2 to pivot in the direction towards each other to the position according to fig. 1.
  • the flexible material portion 12 could instead be arranged to tend to actuate the blade parts 1 and 2 to a position (fig. 3) where they are pivoted away from each other. To obtain the position according to fig. 1 one should thus have to actuate the gripping members 8 and 9 in a direction towards each other by the hand.
  • a material piece forming the blade parts 1 and 2 and the material portion 12 may be constituted of metal as well as plastic.
  • a hinge 4A has not been formed by a flexible material portion but instead by a portion of the one blade part 1, bent to an eye 14, surrounding a portion of the other blade part 2.
  • a hinge 4A has not been formed by a flexible material portion but instead by a portion of the one blade part 1, bent to an eye 14, surrounding a portion of the other blade part 2.
  • an arrangement of one or several spring means in a way known per se is required.
  • the hinge 4B has been formed by means of a piece 15, which connects the blade parts 1 and 2 in that the piece 15 is pivotally connected to each one of the blade parts.
  • the device according to the invention When using the device according to the invention it can in a position according to fig. 1 be used as a conventional cutting device for cutting a cylinder sector shaped piece of cake indicated in fig. 8 with 16 out of a cylindrical cake.
  • the user can by moving the gripping members 8 and 9 apart from each other and grasping one of the gripping members with one hand and the other gripping member with the other hand, apply the device about the piece of cake 16 so that the situation in fig. 8 is obtained.
  • the user has then to see to it that the space between the blade parts 1 and 2 will be of a size corresponding to the piece of cake. Further the blade parts 1 and 2 should of course be brought down in the previously formed cuts at the same time as the hinge should be located at the tip of the piece of cake 16.
  • the device is used in connection with cakes. It is however obvious that the device may be used for grasping and handling and possibly also cutting out other cylinder sector shaped articles than pieces of cake.
  • the device is mainly designed for cylinder sector shaped articles it can also be used for articles with other shapes. However, special advantages occur when the articles have a narrowing shape.
  • the one blade part 2 of the device could be provided with a lip 17 punched downwardly for making the device to operate as a planer for cheese or the like.
  • a hole 18 is obtained in the blade part 2 and a further hole 19 is arranged in the blade part 1, said holes allow passing through of the planed slice.
