Description

{KITCHEN KNIFE WITH PREVENTING ATTACHMENT MEANS}

The present invention relates to a kitchen knife having an anti-sticking means so that foodstuffs that are cut when the food is cut are not attached to the kitchen knife.

Generally, a kitchen knife is a kitchen tool used for cutting food such as vegetables, fruits, meat, fish and the like for cooking. As shown in FIGS. 1 and 2, A knife body 10 having a knife 12 formed thereon and a knob 20 coupled to the rear of the knife body 10.

The blade body 10 of the knife blade is formed of a flat metallic material and is thinner and sharper toward the blade 11. Especially, as shown in FIG. 2, the kinds of vegetables, fruits, tofu and mushrooms among the foodstuffs are attached to the side of the blade body 10 by cutting the foodstuff F while cutting the foodstuff F, This is because the pectin and the water contained in the flat bladder body 10 come into contact with each other so that the sliced vegetables or fruit pieces come into contact with each other and become glued to each other. Therefore, since the food material attached to the blade body 10 must be removed at any time, the speed at which the food material is worn down becomes slow and inconvenient.

In order to solve the problem of attachment of the food material of the kitchen knife according to the related art, there is disclosed in Korean Registered Utility Model No. 20-0472320 (Apr. 04, 2014) a blade member 1 And a knob (2) provided on the rear side of the blade member (1), and is detachably coupled to the knife (2), and has a panel shape extending in the up and down direction and the back and forth direction, (10) formed with a through hole (11) in the longitudinal direction so as to penetrate the blade member (1), and an upper surface of the blade member (1) And a fixing means (20) for allowing the lower end of the panel (10) to be in close contact with the side surface of the blade member (1), wherein when the food material is cut with the knife having the anti - The protective panel 10 And is lifted up by the lower end portion and then dropped by the through hole (11).

However, the conventional anti-sticking device for a kitchen knife has been proposed to prevent food materials (or food ingredients) from adhering to the kitchen knife through the anti-adhesion panel 10, but the lower end of the anti- Only the fixing means 20 fixed to the front and rear ends of the anti-adhesion panel 10 so as to be in close contact with the side surfaces of the blade member 1 may cause insufficient bonding force between the blade member 1 and the anti- There is a problem that the anti-adhesion panel 10 may be pushed upwards or back and forth, or may be detached from the blade member 1. [ That is, when cutting the food material, the lower end front surface of the anti-adhesion panel 10 is continuously impacted by the food material, but only the fixing means 20 ) Is limited to prevent the anti-adhesion panel from being pushed or released from the impact. As the initial contact surface or the lower end surface of the anti-adhesion panel 10 contacting the food material is larger, the impact applied to the anti-adhesion panel 10 is increased, It is not easy to prevent the attachment prevention panel from being pushed or released even if it is formed only by sharpening the blade member 1 in close contact with the blade member 1, There is also a problem.

It is an object of the present invention, which is devised in order to solve the above-mentioned problems, to provide a method of preventing food ingredients from sticking to a knife when slicing a food ingredient and improving bonding force with a knife, So that it is prevented from being pushed or released.

Second, since the contact surface is formed to be uniquely formed so that the contact surface with the sliced food is smaller than that of the conventional art, the sliced food is easily sloped backward while being separated from the contact surface and the crowd can be reduced on the user's wrist while reducing the impact And an anti-sticking means.

The blade body 110 is formed with recesses 113 at the left and right sides thereof. At this time, the protrusion catching grooves 113 of the blade body 110 are formed in the longitudinal direction of the blade body 110 in one or a plurality of directions, The knurled surface 114 may be formed so as to prevent slipping and prevent the locking protrusion 220 from being detached. That is, the protrusion latching recess 113 and the latching protrusion 220 are formed in a state in which the attachment preventing means 200, which is detachably coupled to the knife 100, is in contact with the food material F when cutting the food material F A knurled working surface 114 is formed in the protruding engaging recess 113 to further increase the frictional force between the protruding engaging recess 113 and the engaging protrusion 220 so as to prevent It is possible to prevent the preventing means 200 from being easily separated from the knife 100. The detachment of the attachment preventing means 200 from the knife 100 through the detachable hook 230 included in the attachment preventing means 200 is smoothly performed by the protruding hooking groove 113 and the hooking protrusion 220, And is formed with convex grooves and protrusions so as not to generate gas in the knife 100 in the detaching process. On the other hand, in the field of machining, knurling is a process in which the outer surface of a workpiece having a cylindrical shape is processed in a lattice-like shape in the shape of a rectilinear, a quadratic, or a lattice-like shape in horizontal and vertical directions so as not to slip, Is machined on the convex groove surface of the projection engagement groove 113 so as to increase the frictional force between the knurled surface 113 and the knurled surface 114.

In addition, a graduation line 115 may be displayed on the blade body 110 so that the user can easily check the attachment position of the attachment preventing means 200 to be described later. For example, as shown in FIG. 6, And can be displayed on the blade lamp 112.

The attachment preventing means 200 can be detachably attached to the blade body 110 provided in the knife 100 with an elastic force as shown in FIGS. 4, 5 and 8 to 12 so that the food material F can be removed from the blade body 110 Shaped so as to be fitted into the blade 112 of the blade body 110 and to cover a part of the blade body 110 to prevent the blade body 110 from being attached to the blade body 110. [ At the lower ends of the right and left sides, the contact surface with the food material F is reduced, and the thinned food material F 'is closely attached to the blade body 110 so as to be slanted rearward, 211 and the recessed grooves 212 are mutually connected to form an anti-sticking step 210 arranged at regular intervals. A locking protrusion 220 is formed on an inner surface of the blade body 110 in contact with the blade body 110 to engage with the protrusion receiving groove 113 of the blade body 110, The detachable hook 230 is fixedly coupled. Here, the detachable ring 230 is made of metal or synthetic resin, and has a ring shape in which both ends cut to be detachable to a detachable ring coupling hole 260, which will be described later, can be coupled with each other.

The attachment preventing means 200 has an upper plate 240 whose inner surface is in contact with the blade 112 of the blade body 110 and a lower plate 240 connected to the left and right sides of the upper plate 240, The locking protrusions 220 protrude from the inner surface of the blade body 110 and the attachment prevention protrusions 210 protrude from the inner surface of the blade body 110 at the lower ends thereof. And further includes a pair of elastic plates 250 formed respectively. At this time, the top plate 240 and the elastic plate 250 each have through holes for coupling the detachable hook 230 to the detachable hook 230 so that the bottom of the detachable hook 230 The knife lamp 112 of the knife 100 is brought into close contact with the inner surface of the upper plate 240 to prevent the knife 100 and the attachment preventing means 200 from being protruded from the inside of the elastic plate 250. [ It is possible to further improve the adhesion between them.

The anti-adhesion step 210 is configured such that the contact surface with the food material F becomes smaller and the sliced food material F 'is easily slanted rearward. The protrusion protrusion 211 and the concave groove 212 And the air layer can be formed in the concave groove 212, so that the thinned food material F 'can be guided to be easily separated from the adhesion prevention step 210 by the air layer .

The locking protrusions 220 are formed by punching or injection molding so as to engage with the protrusion engagement grooves 113 of the blade body 100 and to be engaged with the protrusions. That is, the latching protrusion 220 is formed on the inner surface of each of the elastic plates 250. When the elastic plate 250 is made of stainless steel, the latching protrusion 220 is formed by punching. When the elastic plate is made of synthetic resin, . For example, FIGS. 8 and 9 are dotted lines to show that the outer surface of the elastic plate 200 is depressed when the elastic plate 200 is made of stainless steel.

As shown in FIG. 10, the upper plate 240 is bent concavely and concavely to facilitate elastic deformation of the elastic plates 250. When the elastic plate 250 is mounted on the blade body 110, A rubber or silicone anti-slip pad 270 having a knife-inserting hole 271 formed therein is fixedly coupled to an inner surface of the blade body 110, which is in contact with the knife lamp 112, so as not to slide forward and rearward of the blade body 110.

As shown in FIGS. 10 to 12, any one of the pair of elastic plates 250 may be provided on the rear edge of the attachment prevention end 210 so as to be easily engaged with the blade body 110, And a bent portion 280 bent toward the outer side on the right side is formed. That is, although the blade body 110 provided in the knife 100 is shown to be somewhat thick in order to facilitate understanding of the name of each part and the coupling relation, the blade body 112 is made of a flat metallic material so that the food material can be easily cut, The thickness of each of the elastic plates 250 fitted to the cutlery 112 is also very thin because the cutter blade has a shape that is thinner and sharper toward the blade 111. Therefore, 112). Therefore, a bent portion 280 bent in the outward direction on the left or right side at the rear edge of the attachment prevention end 210 is inserted between each elastic plate 250 having a small separation distance so as to facilitate insertion of the blade light 112 A part of the elastic plate 250 on which the bent portion 280 is formed is first inserted into the blade lamp 112 and then the front surface of the upper plate 240 is pressed downward to be easily inserted into the blade body 110 Can be combined. At this time, the bent portion 280 may be formed in the direction of the handle 120 provided on the knife 100 so as not to interfere with the work of writing food ingredients.

Each of the upper plate 240 and the elastic plate 250 may be formed of a stainless steel material or a high strength synthetic resin material so as to have an ∩ 'shape in order to prevent rusting or breakage of the food material containing moisture or rinsing in the washing process. The elastic plate 250 is downwardly bent to have a pointed shape that is inclined to the center as it goes downward so that the sliced food material F 'is sloped backward while being separated from the elastic plate 250, And is integrally formed with the upper plate 240.

Therefore, by pressing the entire contact surface in the longitudinal direction of the front and back sides of the blade body 110 provided in the knife 100 through the upper plate 240 and the elastic plate 250 with the elastic force, It is possible to further increase the bonding force between the blade body 100 and the attachment preventing means 200 as compared with the conventional art in which the front and rear end portions are pressed. Therefore, the attachment preventing means 200 is pushed upward from the blade body 100 Or can be prevented from being detached.

13 and 14, any one of the pair of elastic plates 250 may be provided with a rolled food material F 'sloped rearwardly through the convex protrusions 211 of the attachment prevention end 210, A triangular protrusion 290 having a pointed triangular cross section can be protruded downward on the surface of the convex protrusion 211 of the attachment prevention end 210 so as to be slanted while being separated from the convex protrusion 211 . This is to form a protuberance, which has a triangular cross-section with a pointed downward direction in order to minimize the impact applied while gently contacting with the sliced food material (F '). In other words, in general, the protrusion for preventing the attachment of the food material is protruded in a hemispherical shape. In this case, the food material bumps under the hemispherical protrusion, and the impact applied when the contact is applied is increased. Therefore, the adverse effect There is.

15 and 16 are sectional views respectively showing the separated state and the coupled state between the kitchen knife 100 and the attachment preventing means 200 of the kitchen knife having the anti-sticking means according to the present invention. As described above, the elastic plate 250 The attachment preventive means 200 is inserted into the protruding engagement groove 113 of the blade body 110 and the attachment preventing means 200 of the attachment preventing means 200, 100), and can maintain the joined state. On the contrary, when the attachment preventing means 200 is detached from the knife 100, the user can easily remove the finger by putting his / her finger into the detachable hook 230 and pulling it upward.

17 is a front view showing a state in which food ingredients are cut through a kitchen knife having an anti-sticking means according to the present invention. As shown in FIG. 17, the food material F ' And is positioned correctly. However, if the triangular protrusion 290 is formed on the elastic plate 250 of the anti-adhesion means 200, the contact surface is reduced and the thinned food material F ' It can be quickly released.

Therefore, the kitchen knife having the anti-sticking means according to the present invention is configured such that the first protruding latch groove 113 is recessed, the knife protrusion 220, the elastic plate 250 and the anti-slip pad 270 It is possible to prevent the food material from sticking to the knife 100 when the food material is cut through the attachment preventing means 200 and to prevent the food material from being pushed upward or backward or forward or backward while the food material is being worn There is an effect that can be done.

Secondly, the contact surface with the thinned food material is smaller than that of the prior art through the attachment preventive step 210 including the convex protrusions 211 and the concave grooves 212 and the attachment preventing means 200 including the triangular protrusions 280 The sloped food material is easily slid rearward as it is detached from the contact surface, and there is an effect that the crowd can be reduced on the user's wrist while reducing the impact.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms.
