The plate is made with a bend with a radius of at least 5 cm and a bend connected to the handle.The plate is equipped with holes in the form of notches, the sides of which form sharp spikes on the convex side of the plate facing the body of the fish.This makes it possible to clean fish of any size and with any form of convexity of the body with high productivity due to the fact that the scales do not accumulate under the working surface By the surface of the plate, it is easily removed.The location on the convex side of the sharp spikes facing the body of the fish, formed by the sides of the notches, and the presence of the limb connected to the handle ensures the safety of the fish scaler.

The disadvantages of this fish scaler include an increased level of spraying of scales when cleaning the fish, since the cuttings form sharp and hard spikes.

Closest to the proposed device is a fish scaler (RF patent for utility model No. 85801, published 08/28/2009, IPC: A22C 25/02 (2006.01), A22C 25/14 (2006.01), which is selected as a prototype. The fish scaler includes a plate with spikes and the handle. The plate on the back side is equipped with an annular element, which is closed on the opposite side by a cover, the cover being integral with the handle. The spikes include a working element made in the form of a rectangular parallelepiped, the middle part of the spike is cylindrical in shape and the base of the spike is cylindrical a cone with a rounded bottom is made in the ends of the bases of the studs. Holes are made in the plate, the diameter of which exceeds the gap of the diameter of the middle part of the stud, but less than the diameter of the base of the stud. On the lid from the side of the plate opposite the holes are made of conical protrusions with a rounded top, while the solid angle α of the protrusions of the conical shape is less than the solid angle β of the recesses of the conical shape. The spikes with the middle parts are freely placed in the holes of the plate, and the protrusions of the lid are located inside the recesses at the base of the spikes with the possibility of abutment of the protrusions of the lid in the bottom of the recesses. The centers of the holes in the plate and the spikes placed in them can be located on concentric circles.

The disadvantages of this device include the complexity of the design of the fish scaler.

The technical problem solved by the creation of this invention is to provide high-quality and comfortable cleaning of fish from scales with the lowest level of spraying scales.

The technical result of the invention is to simplify the design of fish scaler, ensuring high-quality and comfortable cleaning of fish from scales with the possibility of ensuring safety when working with fish scaler and reduce the level of spraying scales.

The technical result is achieved by the fact that the fish scaler contains a plate with spikes and a handle. The fish scaler differs from the prototype in that the plate with spikes is made of an elastic material with a modulus of longitudinal elasticity, which makes it possible to provide sufficient resistance to tension and compression during elastic deformation, and having a high coefficient of friction, while the plate is made flat, with spikes in the shape of a truncated cone with a rounded apex located on its lower surface, and with a through hole in the central part, along the perimeter of which there is an inner row of studs installed with an inclination m to the side of the hole at an angle of 30 °, the spikes of the next rows are mounted perpendicular to the bottom plane of the base and are arranged in concentric circles with a staggered offset relative to the spikes of the inner row and the spikes of each subsequent row, while the length of the spikes is proportional to the diameter of their base on the upper surface of the plate there is a handle in the form of a bracket with bends upward, extending beyond the plane of the plate.

The fish scaler plate with spikes can be made of flexible plastic.

The fish scaler plate with spikes can be made of elastomer.

The fish scaler plate with spikes can be made of rubber.

The plate may have, for example, a circular shape in plan.

The invention is illustrated by drawings Fig. 1 - FIG. 3, in which the following species are presented:

FIG. 1 is a sectional view of a fish scaler in front,

FIG. 2 - bottom view of the fish scaler,

Fir. 3 - the location of the spikes during the operation of the fish scaler.

Fish scaler includes the following elements:

1 - plate

2 - spikes,

3 - pen

4 - through hole

5 - bottom surface of the plate,

6 - handle bends,

7 - the upper surface of the plate.

The fish scaler consists of a flat plate 1 with spikes 2 on the lower surface and a handle 3 on the upper surface of the plate, making up a single structure. Moreover, the plate 1 with spikes 2 and the handle 3 are made of an elastic material, for example, plastic compound, elastomer or rubber with a modulus of longitudinal elasticity (Young's modulus) E = (3-6) × 10 ⁶ n / m, which allows providing the possibility of optimal tensile strength and compression under elastic deformation. And also the material for the manufacture of fish scalers should have a coefficient of friction from 0.3 to 0.6. In this case, the plate 1 can have any geometric shape (circle, square, rectangle, polygon).

The spikes 2 can also be different, for example, in the form of a cylinder, cone, prism, pyramid. The most technologically advanced for manufacturing is the shape of a truncated cone with a rounded apex facing the body of the fish during operation. The length of the spikes is proportional to the diameter of their base.

A through hole 4 is made in the central part of the plate 1. An inner row of elastic spikes 2. is installed along the perimeter of the hole 4 on the bottom surface 5 of the plate 1 with a slope inward of the hole 4 at an angle of 30 °. The spikes 2 of the following rows are mounted perpendicular to the bottom surface 5 of the base 1 and are arranged in concentric circles with a staggered offset relative to the spikes 2 of the inner row and subsequent rows.

At the same time, on the upper surface 7 of the plate 1, a handle 3 is made, for example, in the form of a bracket with upward bends 6 extending beyond the plane of the plate 1, which allows fingers to abut against them during fish cleaning in order to reduce the risk of injury.

Work with fish scaler as follows. Conveniently holding the handle 3, located on the upper surface 7 of the plate 1, carry out smooth movements that do not require special effort on the body of the fish lying horizontally in any direction: against the direction of attachment of the scales, in the direction, in circular movements, in any direction. Due to the performance of the plate 1 elastic, working in tension, compression and bending, it always fits snugly against the body of the fish in the place where the spikes 2 come in contact with the scales, allowing the plate 1 to occupy any working position, to glide over the body of fish of any size, while not allowing the scales fly out from under the plate 1. Plate 1 is constantly pressed to the body of the fish at the level of contact of the spikes 2 with the body of the fish and the scales smoothly drain from under the spikes to the edges of the plate 1, while allowing the scales of large fish to pry off perpendicular to the installed spikes 2, and yn small fish is removed through the inner row of studs installed with a slope toward the through hole 4, and is collected in the center hole 4 of the plate 1. scaler during operation periodically immersed in water or placed under running water to wash the collected scales.

In this case, efficient and quick cleaning of fish with any scales is carried out by means of elastic conical spikes 2 located on the lower surface 5 of the plate 1.

Since the fish scaler is made of an elastic material that works under tension, compression and bending, the plate 1 fits snugly against the body of the fish at the point where the spikes 2 come in contact with the scales, allowing the plate 1 to occupy any working position, and not allowing the scales to fly apart. It easily glides over the surface of the fish and completely eliminates hand injuries during work. At the same time, the elastic pins 2 absorb and allow you to quickly and efficiently clean the scales, which practically do not scatter to the sides, but flow smoothly to the edges of the plate 1, falling into the central hole 4, from which the scales can be easily removed as it is filled by a simple rash. The elastic plate 1 eliminates injury to the surface of the fish.

As an example of a specific design, a compact prototype of a fish scaler with a flat plate 1 of a round shape with a diameter of 45 mm from PVC compound with a Young's modulus E = 5 × 10 ⁶ n / m and a friction coefficient of 0.5 was made. A through hole 4 with a diameter of 15 millimeters is made in the central part of the plate 1. On the upper surface 7 of the plate 1, a handle 3 is installed in the form of a bracket with ends 6 bent upwards, which allow fingers to rest against them when cleaning the fish. The spikes 2 are made in the form of a truncated cone with a rounded top, the length of the spikes is proportional to the diameter of their base. On the bottom surface 5 of the plate 1 there are 3 rows of spikes along concentric circles. The inner row of spikes 2 is placed along the contour of the hole 4 with an inclination towards the hole at an angle of 30 °, and the next two rows of spikes 2 are installed perpendicular to the bottom surface 5 of the plate 1 with a staggered offset in each row relative to the inner row of spikes.

Tests of the prototype showed that the proposed design of the fish scaler is simple, convenient to use, providing the ability to carry out high-quality and comfortable cleaning of fish from scales without the risk of injuring hands during work and the lowest level of spraying scales.
