Description

Technical Field [0001] The present invention relates to a method of assembling a grill and a grill,

More particularly, the present invention relates to a method of assembling a wire rope and a wire rope, and more particularly, to a wire rope pulling device which is simple in structure and easy to manufacture and assemble a grill, And to a method of assembling a hollow grill and a grill for convenience of use.

The grill is installed on the top of the grill and is used to bake meat. The grill is usually formed in the form of a netted wire of orthogonal metal wire. However, such a net-shaped grill has a problem that it can not prevent the meat from being pressed during the grilling process, and it is also difficult to wash the pressed meat. Therefore, a net-shaped grill has been mainly used for disposable use.

Such disadvantages of the net shape grill can be greatly improved by the grill formed by arranging and connecting a plurality of wires in a lattice frame in a side-by-side manner without crossing each other, but when the thickness of the wire is thick, Is difficult. Such a problem can be solved by a wire rod formed of thin wire having a thickness of about 0.1 to 2 mm.

However, since the thickness of the wire is small, when the wire is heated in the grinding process, the wire is stretched and the tensile force of the wire is reduced. In other words, the wires of the wire rope have a problem of falling down when the heat is applied. To solve these problems, a variety of grills have been proposed.

Patent Registration No. 10-1359204 (registered on Apr. 28, 2014) discloses a real grill. The disclosed thread grill is formed by a combination of a ring member formed with a plurality of fastening holes and a plurality of wires formed with rings at both ends. The wire is provided with a tension holding portion such as a spring for holding the elasticity of the wire itself. The ring of the wire is engaged with the fastening hole of the ring member. In such a wire rope, the tension holding portion formed on the wire itself adjusts the tension of the wire to prevent the wire from sagging.

In this patent, however, there is a merit that the wire rods can be easily fabricated and assembled and the wire can be prevented from sagging by a simple structure. However, the tension holding portion such as a spring formed integrally with the wire is exposed It is difficult to clean the foreign matter when the foreign matter is caught in the spring, and the grill area of the grill is narrowed by the area where the spring is disposed.

Japanese Patent Application Laid-Open No. 10-2014-0069675 (published Apr. 10, 2014) discloses a grill using thin wire rods. The disclosed grill includes two pairs of outer frame portions, an inner frame portion and a plurality of wire rods. A pair of opposed inner frame portions is provided with a through hole through which the wire rod penetrates. The through hole is formed with a groove in which the first bush and the elastic member are seated, and a groove in which the second bush is seated. The wire rod is inserted into the through hole, and after the elastic member is inserted into the wire rod, it is coupled to the pair of inner frame portions by the first and second bushes. After the wire member is fixed to the inner frame portion, the inner frame portion is inserted into the insertion portion of the outer frame portion in a sliding manner to complete the connection.

However, it is not easy to fix the wire to the inner frame part by the first bushing and the second bushing, and the consistency between the inner frame parts and the matching between the inner frame part and the outer frame part It is not easy to achieve and it is difficult to be practically used.

Patent Registration No. 10-1525378 (registered May 05, 26, 2015) discloses a wire and a grill having the same. The disclosed wire includes a hull, a spring formed by bending from one end of the hull of the wire to the center of the hull, a first bend bent from the other end of the hull, and a second bend bent from the first bend. These wires are fitted to a fixing table composed of a first fixing table and a second fixing table to form a grille. At this time, the spring of the wire is interposed in the space defined by the inner side fixing portion side and the outer side fixing portion side of the first fixing base, and the first bent portion and the second bent portion of the wire are fitted into the hole formed in the second fixing base. The first fixing table is covered by the lid to prevent the spring of the wire from being exposed.

However, since this grill has a plurality of cut-out grooves for inserting the wire into the inner side of the inner side fixing plate, it is not easy to fabricate the first fixing base, and the lid for covering the first fixing base must also have a similar structure. It is not easy to fabricate the semiconductor device.

In addition to the above-described conventional techniques, many structures have been proposed for preventing wire sagging by employing a means for retaining the tension of the wire in a grill. Such a structure is disclosed in Patent Registration No. 10-1114771 (registered on Feb. 02, 2012), Patent Registration No. 10-1262962 (registered on March 31, 2013), Patent Registration No. 10-1426244 (Registration), Patent Publication No. 10-2014-0136108 (Published on April 28, 2014), Utility Model Registration No. 20-0471645 (Registered on April 28, 2014), Utility Model Registration No. 20-0462712 Registration of Utility Model No. 20-0474844 (Registered on October 10, 2014), Registered Utility Model No. 20-474845 (Registered on October 10, 2014), Registered Utility Model No. 20 -0474846 (Registered on October 10, 2014) and Utility Model Registration No. 20-0477525 (Registered on May 12, 2015).

The grill frame 100 is formed in the shape of a rectangular frame as shown in FIG. Of course, if necessary, it may be formed in a frame shape of another polygonal shape, or it may be formed in a circular shape or an elliptical shape. The grill mold 100 is preferably formed in a hollow pipe shape including an upper surface, a lower surface, an outer surface, and an inner surface. The grill frame 100 includes a first engaging portion 110 and a second engaging portion 120 which are disposed at positions opposed to each other and engage with the wire 200. The first engaging portion 110 and the second engaging portion 120 are disposed opposite to each other, And first and second supporting portions 130 and 140 which are coupled to and support the second coupling portion 120 so that the grill mold 100 has a rectangular shape as a whole. At this time, it is preferable that the first coupling part 110, the second coupling part 120, and the first and second supporting parts 130 and 140 are integrally formed. As an example of means for integrally forming, welding is typically used. It is, of course, possible to be combined with a structure which can be separated by screwing.

1 and 2, a portion of the first engaging portion 110 of the grill frame 100 having the upper surface 111, the lower surface 112, the outer surface 113 and the inner surface 114 A plurality of wire tensile force holding means through holes 115 are formed in the outer side surface 113 and a plurality of hull through holes 116 are formed in the inner side surface 114. The wire tension maintaining means through hole 115 is formed literally to penetrate the wire tension maintaining means 220 of the wire 200 and the hull penetration hole 116 literally forms the hull 210 of the wire 200 . The hull 210 of the wire 200 passes through the hull penetration hole 116 but does not pass through the wire tension holding means 220.

Among the portions of the second engaging portion 120 of the grill stove 100 having the upper surface 121, the lower surface 122, the outer side surface 123 and the inner side surface 124, A hole 125 is formed.

The wire tensile force holding means 220 of the wire 200 penetrates the wire tension retaining means through hole 115 so that the outer side surface 113 and the inner side surface 114 of the first engaging portion 110 of the grill mold 100, And the hull 210 of the wire 200 penetrates the hull through hole 116 and is disposed in the space portion 117 formed between the first coupling portion 110 and the second coupling portion 120, respectively. The first end of the wire 200 is coupled to the first coupling portion 110 of the grill mold 100 and the ring 230 of the wire 200 is coupled to the second coupling portion 120 of the grill mold 100. [ The second end portion of the wire 200 engages with the second engaging portion 120 of the grill frame 100. As a result,

2, the wire tensile force holding means 220 includes a wire tensile force holding means (not shown) provided on the outer side surface 113 of the first engaging portion 110 of the grill mold 100, The hull penetration hole 116 provided in the inner side surface 114 of the first coupling portion 110 of the grill frame 100 does not penetrate and the hull 210 of the wire 200 penetrates through the through hole 115, Penetrates the hull through-hole 116. [ The wire tension holding means 220 is disposed in a compressed state by being hooked on the inner side surface 113 of the first engaging portion 110 of the grill stove 100 so that the first end of the wire 200 is held by the grill stall 100, The first engaging portion 110 of the first engaging portion 110 is engaged.

According to this structure, even when the hull 210 of the wire 200 is stretched by heating when using the wire rope 10, the wire tension holding means 220, which is in a compressed state, is restored as much as it is heated, 200 to pull the hull 210 to maintain the tensile force of the wire 200.

Therefore, the grill of the present invention is simple in structure and easy to manufacture and assemble. In addition, the wire rope of the present invention does not expose the wire tension maintaining means such as a spring to the outside, thereby improving the convenience of washing and use.

A process of assembling the grill of the present invention will be described below. The grill 10 of the present invention is characterized in that the grill body 100 is provided with a hull through hole provided in the inner side surface 114 of the first engaging portion 110 of the grill stall 100 in a state where the hook 230 is formed at the second end of the wire 200, (116). Therefore, in the method of assembling the grill of the present invention, the ring 230 of the wire 200 is not formed in advance before the grill is assembled, but the ring 230 is finally attached to the second engaging portion 120 (Not shown).

Specifically, the grill mold 100 described above is prepared. The same wire 200 as described above is prepared except that the ring 230 is not formed at the second end of the wire 200. The hull 210 of the wire 200 is connected to the wire tensioning means through hole 115 provided on the outer side surface 113 of the first engaging portion 110 of the grill mold 100 and the first coupling Through hole 116 provided on the inner side surface 113 of the lower portion 110. In this way, Further, the wire tension holding means 220 of the wire 200 is passed through the wire tension holding means through hole 115. The wire tension holding means 220 is disposed in the space portion 117 formed between the outer side surface 113 and the inner side surface 114 of the first engaging portion 110 of the grill mold 100. [ The hull 210 is then bent at the second end of the hull 210 to form a ring 230. The hook 230 formed at the second end of the hull 210 is inserted into the coupling hole 125 formed in the upper surface 121 of the second coupling portion 120 of the grill frame 100. The second end of the wire 200 then engages with the second engagement portion 120 of the grill mold 100. When the hook 230 at the second end of the hull 210 is fitted into the clamp hole 125 and the second end of the wire 200 is engaged with the second engaging portion 120 of the grill frame 100 The wire tensioning means 220 formed at the first end of the wire 200 is pulled toward the inner side of the first engaging portion 110 of the grill mold 100 The first end portion of the wire 200 is also engaged with the first engaging portion 110 of the grill frame 100. As a result, Therefore, the position at which the ring 230 is formed at the second end of the hull 210 should be appropriately set to satisfy this result.

In order to precisely grasp and form the position where the operator forms the hook 230 at the second end of the hull 210 during the assembly process of the present invention, If the wire 200 is manufactured in advance, it is more convenient to assemble. For example, in the second end of the hull 210, a folding line indicating that the hook 230 should be formed at a position where the hook 230 is to be formed is marked with an indelible ink or the like so that the operator must form the hook 230 The position can be easily grasped. In addition, a slight bend can be formed in advance at the position where the ring 230 is to be formed at the second end of the hull 210. For example, it can be bent at an angle of 10 degrees or less with respect to a straight line hull 210. Such a small angled bent portion is useful for recognizing the bent portion of the wire hull 210 as a position at which the operator should further bend the hook 230 without making the wire hull penetrating through the wire hull penetrating hole 116 difficult .

Although the number of the wires 200 is small and the spacing therebetween is large in the wire rods 10 of FIG. 1, this is only for convenience of drawing, and actually, a much larger number of the wires 200 are provided in the grill frame 100). Therefore, the distance between the wires 200 is so narrow that meat put on the grill 10 can not escape through the wires 200.

1, a plurality of wires 200 are arranged in parallel to each other between the first and second coupling portions 110 and 120 of the grill mold 100, A plurality of wires 200 are arranged between the first and second supporting portions 130 and 140 to reliably prevent meat put on the grill 10 from escaping through the wires 200 It is also possible to constitute the actual grill 10. In this case, the first and second support portions 130 and 140 are formed in the same structure as the first and second engagement portions 110 and 120, respectively, so that they can be named as a third engagement portion and a fourth engagement portion have.

Next, a second embodiment of the present invention will be described with reference to Fig.

The wire rope according to the second embodiment of the present invention is different from that of the first embodiment described above only at the first end portion of the wire 200. [ Therefore, only the other portions will be described below.

The wire tension holding means 220 in the wire rope according to the second embodiment of the present invention is preferably a coil spring formed separately from the wire 210 of the wire 200. This wire tension holding means 220 is fitted to the first end of the wire 200. To prevent wire tension retention means 220 from detaching from the first end of the wire 200 at the first end of the wire 200 to the hull 210 at the first end of the wire 200, . The wire tensile force holding means releasing section 240 may be formed in various forms, for example, a cylindrical metal piece having a through hole through which the hull 210 passes, in the center. The wire pulling force retaining means releasing section 240 composed of a cylindrical metal piece is formed into a cylindrical shape having a diameter larger than the inner diameter of the spring 210 in order to prevent the wire pulling force holding means 220 from separating from the hull 210 . It is preferable that the wire pulling force retaining means releasing region 240 has a cylindrical shape having a diameter corresponding to the outer diameter of the spring as the wire pulling force holding means 220. However,

 The first end of the hull 210 may have a shape larger than the diameter of the hull 210 so as to prevent the wire tension holding means releasing portion 240 from being detached from the hull 210 after being inserted into the hull 210 . One example of the first end of the hull 210 having a shape larger than the diameter of the hull 210 is to press the first end of the hull 210 to flatten the first end of the hull 210, The thickness of the end portion becomes smaller than the diameter of the hull 210 and the width becomes larger than the diameter of the hull 210 so that the marine vessel width expanding portion 260 is formed. The wire tension maintaining means releasing region 240 is thereby prevented from being detached from the hull 210 by the first hull having a wider width, that is, by the hull extending portion 260.

The wire grill according to the second embodiment of the present invention having such a structure is combined with the wire 200 and the grill frame 100 similarly to the above-described method.

3, the wire pulling force holding means 220 and the wire pulling force holding means releasing section 240 are disposed on the same side of the first engaging portion 110 of the grill mold 100 as shown in FIG. The hull through hole 116 provided on the inner side surface 114 of the first coupling portion 110 of the grill frame 100 does not penetrate through the wire tension maintaining means through hole 115 provided on the outer side surface 113 , And the hull 210 of the wire 200 penetrates the hull through-hole 116. The wire tensile force holding means 220 is disposed in a compressed state on the inner surface 113 of the first engaging portion 110 of the grill stove 100 so that the first end of the wire 200 is fixed to the grill stove 100, The first engaging portion 110 of the first engaging portion 110 is engaged.

According to the above-described structure of the wire rope of the present invention, the wire 200 is inserted at the second end into the fastening hole 125 provided in the second engaging portion 120 of the grill frame 100 at the ring 230 And the wire tension holding means 220 at the first end is engaged with the inner side surface 114 of the first engaging portion 110 of the grill mold 100 and held in a compressed state, (200) is coupled to the grill frame (100). According to this structure, even when the hull 210 of the wire 200 is stretched by heating when using the wire rope 10, the wire tension holding means 220, which is in a compressed state, is restored as much as it is heated, 200 to pull the hull 210 to maintain the tensile force of the wire 200.

On the other hand, the wire tensile force holding means 220 contacts and compresses the inner side surface 114 of the first engaging portion 110 of the grill mold 100. In this process, there is a fear that the wire tension holding means 220 may be damaged have. In this case, a wire tensile force retaining means (not shown) having the same shape as that of the wire tension retaining means releasing section 240 can be further inserted into the hull 210 before the wire tension retaining means 220. The wire tension retention means 220 is then positioned between the wire tension retention means release zone 240 and the wire tension retention means protector. Thereby preventing the wire tension holding means 220 from being damaged.

Next, a third embodiment of the present invention will be described with reference to Figs. 4 to 6. Fig. The grill according to the third aspect of the present invention differs from the embodiments described above only in the configuration at the first end of the wire 200. Therefore, only the other portions will be described below.

In the wire rope according to the third aspect of the present invention, the wire tension holding means 220 is preferably a coil spring integrally formed with the hull 210 of the wire 200. The wire tension holding means 220 is formed by being bent from the first end of the hull 210 toward the outside of the hull 210. The wire (200) further includes wire clamping means (250) formed in series with the wire tension holding means (220).

In such a wire rope, the wire tension holding means 220 penetrates the wire tension maintaining means through hole 115, but the hull penetration hole 116 does not penetrate, the hull 210 passes through the hull penetration hole 116, The wire tensile force holding means 220 is disposed in the space portion 117 is the same as that described above. On the other hand, the actual grill according to the third aspect of the present invention is different from the grill of the first and second embodiments described above as follows.

In the wire rope according to the third aspect of the present invention, the wire tension holding means 220 is not arranged in a compressed state but arranged in a tensioned state. The wire tension holding means 220 is hooked on the inner side surface 114 of the first engaging portion 110 of the grill mold 100 so that the first end of the wire 200 is engaged with the first engaging portion 110 of the grill mold 100, The first end of the wire 200 is not engaged with the first engaging portion 110 of the grill mold 100 by the wire engaging means 250 being engaged with the first engaging portion 110 of the grill mold 100, (110).

One example of such wire fastening means 250 is formed of a cylindrical metal piece having a diameter larger than the diameter of the wire tension maintaining means through hole 115, as shown in Fig. A metal or plastic rod having a length longer than the diameter of the wire tension retaining means through hole 115 may be used instead of the cylindrical metal piece in the radial direction of the wire tension retaining means through hole 115.

The assembly process of the grill according to the second to fifth embodiments of the present invention is similar to the assembly process of the grill according to the first embodiment of the present invention. Accordingly, those of ordinary skill in the art will be able to easily carry out the assembly of such a grill with reference to the above description of the present specification, so that a detailed description thereof will be omitted here.

1 to 6, the ring 230 formed at the second end of the wire 200 is formed by bending the hull 210 only once. The wire 200 can be stably engaged with the second engaging portion 120 of the grill frame 100 by being fitted into the fastening hole 125 even in the form of the ring 230 having such a simple shape, 200 may be pulled out of the fastening hole 125, an annular shape as shown in Fig. 7 may be employed.

The ring 230 shown in FIG. 7 has a first bent portion 231 bent at an acute angle from the hull 210 and a second bent portion 232 bent at an acute angle from the first bent portion 231. Therefore, the ring 230 has an alphabet Z character as a whole. Such a ring shape is as disclosed in Patent Registration No. 10-1525378.
