Description

How to Assemble the Grill and Seal

The present invention relates to a method of assembling a gasket and a gasket, and more particularly, the structure is simple and easy to manufacture and assemble the grate, wire tension maintaining means for tensioning the grate wire, such as a spring to the outside The present invention relates to a seal and a method of assembling the lock, which is convenient for use due to no exposure.

The grill is installed on the top of the grill and used to grill meat. The grill is usually formed in the form of a mesh woven orthogonal to the metal wire. By the way, such grill grille of the mesh type not only has a problem that can not prevent the meat sticking in the roasting process, but also has a problem that it is difficult to wash the pressed meat. Thus, grills in the form of meshes have been used primarily for single use.

These drawbacks of mesh grills can be significantly improved by grills formed by joining a number of wires side by side without crossing the grille. However, if the thickness of the wire is thick, the meat sticks. Is difficult. This problem can be solved by the sills formed of wire having a thickness of about 0.1 to 2 mm.

However, since the thread is thin in the thickness of the wire, there is a problem in that when the heat is applied to the wire in the roasting process, the wire is stretched to reduce the tensile force of the wire. That is, there was a problem that the wire of the silt sag down when heat is applied. Various locks have been proposed to solve this problem of locks.

Patent Registration No. 10-1359204 (registered on January 28, 2014) discloses a lock. The disclosed sills are formed by combining a ring member having a plurality of fastening holes and a plurality of wires having rings formed at both ends thereof. The wire is formed with a tension holding part such as a spring for maintaining the elasticity of the wire itself. The hook of the wire is fitted into the fastening hole of the ring member to engage. The tension holding part formed on the wire itself in such a silt prevents the wire from sagging by adjusting the tension force of the wire.

By the way, this patent key has a merit that it is easy to manufacture and assemble the key by a simple structure and can prevent the wire from sagging, but the tension holding part such as a spring formed integrally with the wire is exposed from the key. Since there is a structure that the foreign material is caught in the spring during the use of the actual grill can cause a difficulty in cleaning, so the grilling area of the grill is narrowed as much as the spring is arranged.

Korean Patent Publication No. 10-2014-0069675 (June 10, 2014) discloses a grill using thin wire. The grill is disclosed comprising two pairs of outer frame portions, inner frame portions and a plurality of wire rods.

The wire rod is fitted into the through hole, and the elastic member is inserted into the wire rod and then coupled to the pair of inner frame portions by the first bushing and the second bushing. After the wire rod is fixed to the inner frame part, the coupling is completed by sliding the inner frame part to the insertion part of the outer frame part.

However, the grille is simple in its components, but it is not easy to fix the wire rod to the inner frame part by the first bushing and the second bushing, and the matching between the inner frame parts and the consistency between the inner frame part and the outer frame part are not easy.

Looking at the process of assembling the gasket of the present invention. The sills 10 of the present invention have a through hole provided in the inner surface 114 of the first coupling portion 110 of the grill frame 100 in a state where the ring 230 is formed at the second end of the wire 200. Cannot pass (116). Therefore, in the method of assembling the sills of the present invention, the ring 230 of the wire 200 is not formed in advance before assembling the sills, but finally, the rings 230 are secondly coupled to the grill frame 100. It is formed when fitting in the fastening hole 125 provided in).

Specifically, the grille frame 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. Wire hull 210 of the wire 200 is provided on the outer surface 113 of the first coupling portion 110 of the grill frame 100 through the wire tension holding means through hole 115 and the first coupling of the grill frame 100 It penetrates through the hull through hole 116 provided in the inner side surface 113 of the part 110 in order.

Thereafter, the hull 210 is bent at the second end of the hull 210 to form a ring 230. The ring 230 formed at the second end of the hull 210 is inserted into the fastening hole 125 formed in the upper surface 121 of the second coupling portion 120 of the grill frame 100. Then, the second end of the wire 200 is coupled to the second coupling portion 120 of the grill frame 100. In addition, when the ring 230 at the second end of the hull 210 is fitted into the fastening hole 125 so that the second end of the wire 200 engages with the second coupling portion 120 of the grill frame 100. , The hull 210 is pulled toward the second end, and then the wire tension maintaining means 220 formed at the first end of the wire 200 is the inner surface of the first coupling portion 110 of the grill frame 100 ( The first end of the wire 200 is also coupled to the first coupling portion 110 of the grill 100 by being in a compressed state in close contact with the 114. Therefore, the position at which the ring 230 is formed at the second end of the hull 210 should be set appropriately to satisfy this result.

In order to accurately identify and implement the position where the operator forms the ring 230 at the second end of the hull 210 in the assembly process of the sills of the present invention, the position where the ring 230 should be formed is displayed in advance. If the wire 200 is manufactured in advance, it is more convenient to assemble. For example, the operator should form the ring 230 by marking the bent line with indelible ink or the like, which indicates that the ring 230 should be bent at the second end of the hull 210. The location can be easily identified. In addition, some bending may be formed in advance at a position where the ring 230 is to be formed at the second end of the hull 210. For example, the straight hull 210 may be bent at an angle of 10 degrees or less. Then, such a small angle bent portion can be usefully used to recognize the position where the operator should bend to form the ring 230 without making it difficult to penetrate the wire hull 210 through the wire hull through-hole 116. Can be.

Although the number of wires 200 and the spacing between them are widely shown in the sills 10 of FIG. 1, this is merely for convenience of drawing, and in practice, a much larger number of wires 200 are grilled ( 100). Thus, the spacing between the wires 200 is very narrow so that the meat placed on the sills 10 does not escape between the wires 200.

In addition, FIG. 1 illustrates a thread grate 10 in which a plurality of wires 200 are arranged side by side only between the first coupling part and the

second coupling part

110 and 120 of the grill frame 100. According to the structure in which a plurality of wires 200 are arranged between the first and

second support portions

130 and 140 in order to ensure that the meat placed on the lock 10 to escape between the wires 200 It is also possible to configure 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 coupling portion and the

second coupling portion

110 and 120, respectively, and thus may be referred to as the third coupling portion and the fourth coupling portion. have.

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

The slipper according to the second embodiment of the present invention differs from that of the first embodiment described above only in the configuration at the first end of the wire 200. Therefore, only other parts will be described below.

In the sills according to the second embodiment of the present invention, the wire tension maintaining means 220 is preferably a coil spring formed separately from the hull 210 of the wire 200. The wire tension maintaining means 220 is fitted to the first end of the wire 200. In order to prevent the wire tension maintaining means 220 from the first end from the first end of the wire 200 to the hull 210 at the first end of the wire 200 at the first end of the wire 200 is wire tension maintaining means release prevention 240 ) Is inserted. The wire tension maintaining means release prevention tool 240 may be configured in various forms, for example, may be composed of a cylindrical metal piece having a through hole through which the hull 210 penetrates in the center. The wire tension maintaining means release prevention device 240 composed of a cylindrical metal piece is formed in a cylindrical shape having a diameter larger than the inner diameter of the spring to prevent the wire tension maintaining means 220 from being separated from the hull 210. Should be. The wire tension maintaining means release prevention unit 240 is preferably a cylindrical shape having a diameter that matches the outer diameter of the spring which is the wire tension maintaining means 220, but it is not necessary to match the diameter.

In addition, the first end portion of the hull 210 to have a shape larger than the diameter of the hull 210 in order to prevent the wire tension maintaining means release preventing device 240 is separated from the hull 210 after being fitted to the hull 210. Can be. One example in which the first end of the hull 210 has a shape larger than the diameter of the hull 210 is to press the first end of the hull 210 to flatten it, and thus the first end of the hull 210 is formed by the stretching property of the metal. The end portion has a thickness smaller than the diameter of the hull 210 and the width is larger than the diameter of the hull 210 to form the hull end width extension 260. Then, the wire tension maintaining means release prevention unit 240 is prevented from being separated from the hull 210 by the first wide end of the hull, that is, by the hull end width expansion 260.

In the silb according to the second embodiment of the present invention having such a configuration, the wire 200 and the grille frame 100 are coupled to each other in a manner similar to that described above.

In addition, the wire tension maintaining means 220 is disposed in a compressed state by being condensed on the inner surface 113 of the first coupling portion 110 of the grill frame 100, so that the first end of the wire 200 is grilled 100. It is coupled with the first coupling portion 110 of the.

On the other hand, the wire tension maintaining means 220 is in contact with the inner surface 114 of the first coupling portion 110 of the grill frame 100 and compressed, there is a risk that the wire tension maintaining means 220 is damaged in this process have. In this case, a wire tension maintaining means protector (not shown) having the same shape as the wire tension maintaining means release preventing device 240 may be fitted to the hull 210 before the wire tension maintaining means 220. Then, the wire tension maintaining means 220 is located between the wire tension maintaining means escape prevention device 240 and the wire tension maintaining means protector. As a result, damage to the wire tension maintaining means 220 can be prevented.

Next, with reference to FIGS. 4-6, the 3rd aspect of this invention is demonstrated.

One example of such a wire locking means 250 is to be 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. Instead of the cylindrical metal piece, a metal or plastic rod having a length longer than the diameter of the wire tension maintaining means through-hole 115 may be used to be hung in the radial direction of the wire tension maintaining means through-hole 115.

The assembling process for the sills according to the second to fifth embodiments of the present invention is similar to the assembling process for the sills according to the first embodiment of the present invention. Therefore, those skilled in the art will be able to easily perform such assembly of the grating with reference to the above description of the present specification, and thus the detailed description thereof will be omitted.

Meanwhile, the ring 230 formed at the second end of the wire 200 in FIGS. 1 to 6 is illustrated by bending the hull 210 only once. In general, the wire 200 is stably coupled to the second coupling portion 120 of the grill frame 100 by being fitted into the fastening hole 125 even in the form of such a simple ring 230, but the wire ( In the case where the 200 is concerned to fall out of the fastening hole 125, a ring 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 a Z letter shape as a whole. This ring shape is as disclosed in Patent Registration No. 10-1525378.
