Description

The utility model relates to devices for smoking cigars or cigarettes, namely to cigar scissors, and can be used to cut cigars before using them [A24F 13/00, A24F 13/24, A24F 13/26, B26D 1/30].

The prior art CIGA CUTTER FOR TABLE USE [FR 2390115, publ. 12/08/1978], consisting of a flat base on legs, on which the guide columns for the guillotine knife are held; cigars are stored in a coffin-shaped box on the base, and the cigar is placed on a cutting board in front of a support fixed at the bottom of the columns, which is held by a similar support above it; the end of the cigar is cut off by pressing the latch on the side of the column, this releases the raised guillotine knife, and the severed end falls into the basket.

Also known TOWER GUILLOTINE CUTTER FOR CIGARS [US 6049984, publ. 04/18/2000], containing spaced twin towers with an upper crossbar on the base, with a movable knife block and a blade that rises vertically on a rope between the towers. Upon release, the cutting blade and block fall onto the lower block, which has a channel for the blade, thereby cutting off the end of the cigar. The cutting block has adjacent holes in the shape of a semicircle to receive the tip of the cigar. The movable cutting unit when ascending the rope is released when the escapement mechanism on the rope touches the crossbar. A locking device prevents the cutting unit from moving vertically out of the lower unit when not in use.

A common disadvantage of these analogs is the increased complexity of the design, as well as the low resource of the blade due to the use of steel as a material for the manufacture of the blade, which, if the sharpness of the blade edge loses over time, can lead to crumpling and the formation of tatters and tears of the cigar cover sheet.

The closest in technical essence is a GUILLOTINE WITH LEUKOSAPPHIRE BLADE FOR CUTTING CIGARS [RU 138655, publ. 03/20/2013], characterized in that the cutting element is made of leucosapphire, which, due to its hardness, has a sharp cutting edge and a long service life.

The main technical problem of the prototype is the need for additional adjustment of the position of the cigar before cutting in order to accurately set the cut line, which entails additional time and can lead to a loss in the accuracy of cutting the cigar.

The purpose of the utility model is to eliminate the shortcomings of the prototype.

The technical result of the utility model is to increase the accuracy of the cut of the cigar and the resource of the knife blade.

This technical result is achieved due to the fact that the guillotine for cigars, containing a movable part with a knife and a fixed part with a cavity for the knife, in the fixed part there is a hole for the cigar, along which the knife moves inside the cavity, characterized in that the knife is made of sapphire, the edge knife blade is beveled at an acute angle to the vertical, in the moving part in the center above the knife a light source is mounted, the luminous flux from which is directed through the knife blade down to the fixed part, the light source is connected to the power source through an electric key, which turns on the light source when raised and the knife removed from the fixed part and turns off the light source when the knife is lowered inward into the cavity of the fixed part.

In particular, the movable part is movable relative to the fixed part by means of guides mounted to the movable part and moving along holes made in the fixed part.

Brief description of the drawing.

The figure shows a guillotine for cigars in a section, which indicates: 1 - body, 2 - cylindrical holes, 3 - cover, 4 - guides, 5 - knife, 6 - cavity, 7 - cigar hole, 8 - LED, 9 - compartment, α - bevel angle of the edge of the knife blade to the vertical.

The guillotine for cigars contains a fixed part, made in the form of a body 1, inside which in the left and right parts, symmetrically with respect to the vertical axis of symmetry, vertical cylindrical holes 2 are made, as well as a movable part, made in the form of a cover 3, in which symmetrically with respect to the vertical axis of symmetry are mounted vertically downward guides 4, made with the possibility of their reciprocating movements together with the cover 3 inside the said cylindrical holes 2 in the housing 1.

In the lower part of the cover 3, between the guides 4, a knife 5 is fixed, the edge of the blade of which is directed downwards and is beveled at an acute angle α to the vertical.

Inside, along the body 1, a cavity 6 is made with the possibility of placing and moving a knife 5 in it.

In the middle part, across the body 1 and the cavity 6, a round through hole 7 is made, made with the possibility of installing a cigar for trimming.

In the upper part of the cover 3, at least one light source is fixed, made in the form of an LED 8 with the possibility of directing the light flux down to the upper edge of the knife 5 to illuminate the knife blade 5 and through the knife blade 5 forming a cigar cut line (not shown in the figure) .

Inside the case 1, in its lower part, a compartment 9 is made, in which an electric key and a power source (not shown in the figure) of the LED 8 are mounted.

The body 1 is made of metal, for example, bronze or steel.

Guides 4 are made of metal, for example, steel, bronze or chromium.

The guides 4 are mounted to the cover 3 with a detachable or one-piece connection.

The claimed technical solution is used as follows.

To use the guillotine for cigars, the lid 3 is raised as intended, while the knife 5 fixed in the lid 3, moving upwards in the cavity 6, releases the hole for the cigar 7, into which the cigar is placed.

Cylindrical holes 2, made in the body 1 with the possibility of reciprocating movement of the guides 4 inside them, ensure the movement of the cover 3 up and down and exclude displacement in the transverse direction of the body 1 and the cover 3 relative to each other.

When the cover 3 reaches the upper position, the electric key placed in the compartment 9 turns on the LED 8, which is powered from the power source.

The optical properties of sapphire, from which knife 5 is made, are such that the light flux from LED 8, falling on the upper surface of knife 5, passes down through the entire body of knife 5, illuminating its blade, and forms a cut line on the cigar.

Further, applying some force at the moment of contact of the lower edge of the blade of the knife 5 with the cigar, the cover 3 is lowered down, while the knife 5 cuts off the end of the cigar exactly along the line formed by the illumination from the LED 8.

When the knife 5 reaches the lower position, after cutting off the end of the cigar, the LED 8 turns off.

To improve the cutting properties, the edge of the blade of the sapphire knife 5 is beveled at an acute angle α to the vertical. The preferred range is α=45°…58°: at α<45°, the probability of tearing the edge of the wrapping paper of the cigar increases, at α>58°, the required blade pressure force on the cigar increases and the blade resource decreases.

In various embodiments, the sapphire knife 5 can be made mechanically sharpened or additionally thermochemically. In the second variant, a defective layer 5–20 µm thick is etched from the sapphire knife 5, which gives additional sharpness to the blade, and the cutting edge and planes of the sapphire knife 5 become smoother.

The technical result of the utility model - increasing the accuracy of the cigar cut and the life of the knife blade - is achieved through the use of LED 8, the luminous flux from which exactly forms the cut line of the cigar and eliminates the need for additional adjustment of the position of the cigar before cutting in order to accurately set the cut line, as well as due to the use of sapphire for the manufacture of the blade of the knife 5, which, due to its crystalline structure and high hardness, retains its properties for a long time, which ensures that the cut of the cigar is even and prevents crumpling and the formation of tatters and tears of the cover sheet of the cigar.

An additional technical result is an increase in the structural strength of the guillotine due to the execution of the body 1 and guides 4 of hard and durable materials - steel, bronze or chromium, as well as a reduction in size due to the execution of the guillotine in the form of a single block without the use of external parts complicating the design.

In 2021, the author of the utility model manufactured, in accordance with the description, an experimental batch of guillotines for cigars, which were tested using various types of cigars for 6 months.

The bodies of the guillotines from the experimental batch were made of bronze or steel, the guides were made of steel, bronze or chromium. Guides in various implementations were fixed in the grooves of the guillotine cover by means of a pin, threaded or adhesive connection.

Samples were also made in accordance with the descriptions of analogues and the prototype (patents FR 2390115, US 6049984, RU 138655).

The claimed technical solution during comparative tests with the mentioned samples showed clear advantages, which are as follows:

- in comparison with knife blades made of steel, sapphire blades allow to obtain a sharper cutting edge (up to values less than 1 micron), and due to their high hardness, they retain long-term cutting properties, which also facilitates operation;

- the proposed technical solution regarding the use of LED illumination of the knife and the cut line of the cigar made it possible to ensure an even cut without additional adjustment of the position of the cigar and, thus, saving time and facilitating the operation of the guillotine;

- the implementation of the guillotine in a single body without the use of external parts made it possible to achieve compactness and convenience of design, which leads to an improvement in the performance properties of the claimed technical solution during its implementation.
