CURLING STONE AND MANUFACTURING METHOD THEREOF [0002]

The present invention relates to a curling stone and a method of manufacturing the same, and more particularly, to a curling stone and a method of manufacturing the same. More particularly, the present invention can be applied not only to ice plates but also to curling stadiums made of materials other than ice plates, The present invention relates to a curling stone and a method for manufacturing the curling stone.

In general, curling refers to a game in which an ice sheet slides a flat stone [boulder] into a broom (comb), and puts it into the target to compete for scoring.

The birthplace of the game was Scotland, and it was said to have been active around the 16th century.

The earliest stone was a large stone with a hole to hold it with a finger, but iron was used instead of stone in the 1800s. At one time, more than 100 lb (45.4 kg) was used and is done. In 1838, the Grand (currently the Royal) Caledonian Curling Club was founded in Scotland and became the foundation upon which it was merged into an international curling club.

Canada was an early adopter of curling, and in 1807 formed the Royal Montreal Club.

The 1927 Canadian Championships began, and the World Championships are held annually since 1959. Canada, North America, Europe, and New Zealand.

The curling method is composed of two teams of four teams each. In the link of 42.1m in length and 4.3m in width, two stones are alternately slid on the target in the circle called the house, Compete for points depending on whether you went.

The stone is 20kg or less in weight, 91.4cm or less in circumference, and 11.4cm in height. Sixteen rounds are used as one end, and 10 or 12 rounds are used as one game, and the game is blocked depending on the score somewhat.

However, unlike Canada, which is an origin of curling, Scotland, which is an early adopter of curling, there is not a long winter, and there are few indoor arenas with ice rinks.

To this end, an air curling unit (Utility Model Registration No. 20-0436642) has been registered in which curling can be popularly enjoyed.

However, such an air curling unit is difficult to realize the shape of a real curling stone, and when it is the same as an actual curling stone, it becomes difficult to obtain a floating strength, so that the fun of the game is reduced and the practical sense can not be learned.

In addition, in the past, curling stones are not only expensive but also difficult to purchase, so that the curling game can not be easily spread.

The conventional curling stone can be used on an ice sheet or on a sheet other than an ice sheet as in the Utility Model Registration No. 20-04366, and can not be used simultaneously in an ice sheet and a plain sheet.

The curling stone according to the present invention comprises a curling stone body 10, a first running plate 20, a second running plate 30, and a handle 40.

The curling stone body 10 has a lower mounting groove 13 formed at a lower portion including a portion in contact with the bottom surface when the curling stone body 10 is placed on a floor surface and a through hole 15 formed at a center thereof in a height direction. An upper mounting groove 11 having the same size and shape as the lower mounting groove 13 may be further provided on the curling stone body 10.

At this time, it is preferable that the upper mounting groove 11 has a size that can be shielded by the handle 40. Here, since the upper mounting groove 11 is the same size and shape as the lower mounting groove 13, it is natural that the lower mounting groove 13 can be shielded by the grip 40 as well.

The curling stone body 10 is made of a synthetic resin material and is made of an acrylic resin, an epoxy resin, an urethane resin, an MMA resin, a rubber, a plastic, an unsaturated resin, UHMWPE (Ultra High Molecular Weight Poly Ethylene) It is made in one. However, the synthetic resin material is not limited thereto, and a variety of materials for children and curling stones having relatively low strength by weight reduction can be applied.

The curling stone body 10 may be formed by mixing at least one material selected from pearl, stone powder, silica sand, calcium carbonate, and phosphorescent material in the synthetic resin. In addition, in order to increase the weight of the curling stone body 10, the curling stone body 10 may be formed by mixing heavy materials such as steel making slag, metal body, and aggregate with the synthetic resin.

The first running plate 20 is disposed in any one of the upper mounting groove 11 and the lower mounting groove 13 and a first fastening hole 21 penetrating through the center in the height direction is formed. The first running plate 20 is made of stone, and it may be manufactured by processing a stone or mixing a stone piece or a stone powder with a synthetic resin.

The second running plate 30 is made of a synthetic resin material and is preferably made of an epoxy resin or Ultra High Molecular Weight Poly Ethylene (UHMWPE) to facilitate slippery operation.

As shown in FIG. 3, the friction reducing portion may include a projection 33, a bearing (not shown), or the like.

The handle 40 has a handle 41 at the upper end and a nut member 45 at the lower end. The bolts 43 inserted through the fastening holes 21 or 31 of the first running plate 20 and the second running plate 30 mounted on the lower mounting groove 13 are engaged with the washers 44 The through hole 15 of the curling stone body 10 and the other one of the first traveling plate 20 and the second traveling plate 30 mounted on the upper mounting groove 11, Is fastened to a nut member (45) formed at the lower end of the handle (40) through the fastening holes (21 or 31) and mounted on the first travel plate (20) or the second travel plate (30).

When the curling stone according to the present invention is used in an ice plate, the first running plate 20 made of stone is attached to the lower mounting groove 13, and the same as the curling stone made of actual granite (See FIG. 4). When the curling stone according to the present invention is used in a curling arena (for example, a film or sheet of a synthetic resin material) made of other material than an ice plate, The second running plate 30 provided with the friction reducing portion can be attached to the lower mounting groove 13 so that the running characteristics of the curling stone can be exerted on such a film or sheet similarly to the ice plate.

In addition, when the curling stone body 10 is manufactured, it is possible to exhibit an external effect according to each material by mixing pearl, stone powder, silica sand, calcium carbonate, and phosphorescent material, Aggregates and the like can be mixed to produce a curling stone having a desired weight, so that the curling game can be enjoyed according to the physique and taste of the user.

Next, a method of manufacturing a curling stone according to the present invention will be described.

FIG. 5 is a flow chart showing a method of manufacturing a curling stone according to the present invention, FIG. 6 is a view showing a configuration of an outer frame according to the present invention, FIG. 7 is a view showing a configuration of an outer frame and an inner frame according to the present invention Fig.

As shown in the drawings, the present invention is characterized in that a first running plate 20 made of a stone used for producing an actual curling stone, a second running plate 30 made of a synthetic resin material and having a friction reducing portion formed on the bottom surface thereof, The first driving plate 20 or the second driving plate 30 is attached to the upper and lower mounting grooves 11 and 13 of the stone body 10 in accordance with the bottom condition of the curling stadium, The present invention relates to a method of manufacturing a curling stone capable of performing a curling game by being mounted on a mounting groove (13).

The manufacturing method of the curling stone includes a step (S10) of manufacturing the curling stone body 10, a step (S20) of manufacturing the first traveling plate 20 and the second traveling plate 30, (S30) of arranging the second running plate on the curling stone body (10), and integrating the curling stone body (10) with one of the first running plate (20) and the second running plate (30) (Step S40).

The curling stone body 10 is formed with a lower mounting groove 13 at a lower portion including a portion in contact with the floor surface when the curling stone body 10 is placed on the floor surface, Through holes 15 are formed in the direction of the arrows.

At this time, the curling stone body may be manufactured such that an upper mounting groove 11 having the same size and shape as the lower mounting groove is further formed on the curling stone body. In this case, it is preferable that the upper mounting groove 11 has a size that can be shielded by the handle 40.

When the upper mounting groove 11 is formed and one of the first running plate 20 and the second running plate 30 is mounted to the lower mounting groove 13, (11), and can be shielded by the grip portion (40), so that it is easy to store an unused travel plate.

This curling stone body 10 starts from the step of manufacturing the outer frame 50 larger than the diameter and height of the curling stone. The outer frame 50 is divided into two parts so that two pieces of the outer frame 50 are formed. 6 and 7, the outer frame 50 includes an upper frame 51 and a lower frame 53.

An upper groove 51a for forming the upper mounting groove 11 is formed in the upper frame 51 in a predetermined size and shape and the lower mounting groove 13 is formed in the lower frame 53 in a predetermined size and shape. A lower trench 53a is formed. Here, the constant size and shape mean a size and a shape including a portion in contact with the bottom surface when the curling stone body 10 is placed on the floor, and the upper mounting groove 11 and the lower mounting groove 13, The size and shape of the upper groove 51a and the lower groove 53a are the same (S11).

The upper frame 51 and the lower frame 53 are formed with fixing portions 51b and 53b for fixing and fixing the inner frame 60 to be described later. The fixing portion also functions to form a through hole 15 in the curling stone body 10.

The inner frame 60 formed to be smaller than the curling stone body 10 is fixed by the fixing portions 51b and 53b inside the outer frame 50 so that the curling stone body 10 has a predetermined thickness or more And an air layer 17 may be formed on the inside thereof.

In addition, at least one iron ball (not shown) may be incorporated in the air layer 17 so that the curling stone is biased to the right or left according to the direction in which the iron ball moves in the air layer 17 (S12) .

Next, in the step of inserting the synthetic resin, synthetic resin is injected and cured in a state where the inner frame 60 is mounted on the upper frame 51 of the outer frame 50, The synthetic resin is put in the state that the inner frame (60) is mounted and hardened. That is, when the primary body 10 'is produced, the upper body 10'a constituting the upper body and the lower body 10'b constituting the lower body are individually manufactured and joined to form the primary body 10' ').

This is because when the synthetic resin is injected in a state in which the upper frame and the lower frame are coupled to each other, a space in which the synthetic resin is not filled due to the upper mounting grooves and the lower mounting grooves may be generated. Therefore, the synthetic resin is separately supplied to the upper frame and the lower frame, will be. However, this embodiment is merely one example in which the upper mounting groove and the lower mounting groove can be filled with synthetic resin, and it is a matter of course that other methods other than the above-described method can be applied.

Such a synthetic resin may be composed of one of acrylic, epoxy, urethane, MMA (plastic resin raw material), rubber, plastic, unsaturated resin, UHMWPE (Ultra High Molecular Weight Poly Ethylene) However, the synthetic resin material is not limited thereto, and various materials for the idler and the female curling stone, which are relatively weak in strength, can be applied by reducing the weight, and the steel making slag, the metal body, , The weight of the curling stone is increased in such a manner that the weight increasing material mixed with one or more of the silica sand is mixed with the synthetic resin and inserted.

Further, other materials may be added to the synthetic resin for various appearance and performance of the curling stone body 10. More specifically, additives such as pearl, stone powder, silica sand, calcium carbonate, and phosphorescent material may be added to the synthetic resin, and the amount of the additive incorporated is determined in consideration of the intended weight and the unit weight of the synthetic resin to be incorporated (S13).

Next, when the synthetic resin is hardened in the outer frame 50, the outer frame 50 is disassembled to produce a basic body larger than the diameter and height of the actual curling stone. At this time, as shown in FIG. 7 (a), the synthetic resin is injected and cured to form the upper body 10'a while the inner frame 60 is installed in the upper frame 51 of the outer frame, 7 (b), a synthetic resin is injected and cured to form a lower body 10'b in a state where the inner frame 60 is installed in the lower frame 53 of the outer frame, The upper body and the lower body are coupled to each other to produce the basic body 10 'as shown in (c) of FIG.

The curling stone body 10 is fabricated by polishing the outer surface of the main body to form an outer shape of the curling stone. At this time, silk printing, embossing and embossing may be applied to the curling stone body 10 to exhibit an advertisement effect. The appearance of the curling stone body 10 may be a size used for an official curling game. However, The appearance may be changed (S14).

As shown in Fig. 2, a through-hole 15 penetrating through the center of the curling stone body 10 in a height direction is formed in the curling stone body 10 manufactured as described above. The through hole 15 is used for mounting the handle 40 on the curling stone body 10 together with the first and second running plates 20 and 30 to be described below.

The first running plate 20 is provided with a first fastening hole 21 penetrating through the center in a height direction and is formed in a size and shape conforming to the upper mounting groove 11 and the lower mounting groove 13 do. The first running plate 20 is made of stone, and may be manufactured by processing the raw stones into shapes and sizes, or may be manufactured by mixing stone pieces or stone powder with synthetic resin.

 The second running plate 30 is provided with a second fastening hole 31 penetrating through the center in a height direction and is formed in a size and shape conforming to the upper mounting groove 11 and the lower mounting groove 13. [ At this time, a projection 33 is formed on the bottom surface of the second running plate 30 as a friction reducing portion for reducing friction with the bottom surface.

The second running plate 30 is made of a synthetic resin material and is preferably made of epoxy resin or Ultra High Molecular Weight Polyethylene (UHMWPE) to facilitate slip (S20).

The first travel plate 20 and the second travel plate 30 are disposed in the upper mounting groove 11 or the lower mounting groove 13 of the curling stone body 10. [ That is, when the first running plate 20 is disposed in the upper mounting groove 11, the second running plate 30 is disposed in the lower mounting groove 13, and vice versa. When the curling stone according to the present invention is used in an ice plate, a first running plate 20 made of stone is formed in a lower mounting groove (not shown) so as to exhibit running characteristics for an ice plate, 4). When the curling stone according to the present invention is used in a curling arena (for example, a film or sheet of a synthetic resin material) made of a material other than an ice sheet, The second running plate 30 provided with the friction reducing portion such as the protrusion 33 or the like can be mounted to the lower mounting groove 13 in order to exhibit the running characteristics of the curling stone similarly to the ice plate (See Fig. 3, S30).

The curling stone body 10, the first running plate 20 and the second running plate 30 manufactured in this way are combined with each other to form a bolt 43 and a nut Coupling is used. That is, the bolts 43 inserted through the fastening holes of the first running plate 20 and the second running plate 30 mounted in the lower mounting groove 13 with the washer 44 inserted therebetween, Passes through the through hole 15 of the curling stone body 10 and the fastening hole of the other one of the first traveling plate 20 and the second traveling plate 30 mounted on the upper mounting groove 11 The handle 40 is fastened to the nut member 45 formed at the lower end of the handle 40 and the handle 40 is mounted on the first drive plate 20 or the second drive plate 30 at step S40.

According to the method of manufacturing a curling stone according to the present invention as described above, a traveling plate suitable for the characteristics of the curling field is installed at the lower part of the curling stadium made of an ice plate and the curling field made of other materials, So that a curling game can be performed.

In addition, when the curling stone body 10 is manufactured, it is possible to exhibit an external effect according to each material by mixing pearl, stone powder, silica sand, calcium carbonate, and phosphorescent material, Aggregates and the like can be mixed to produce a curling stone having a desired weight, so that the curling game can be enjoyed according to the physique and taste of the user.
