Abstract

A latch link is completed by combining a latch and a hook without any additional parts. The latch and the hook are manufactured by a method which combines the enhanced elasticity of each part formed by processing molding and the elasticity of a metal itself. In a construction method in which pressure tension is induced in the bar connection, and which uses the unchanging elasticity of the arch-shaped central multisection, a hemispherical embossing is formed. The apex of the hemispherical embossing stimulates the latch from the moment of being inserted into the inner diameter of the latch, causing pressure and tension to continue. Accordingly, it is possible to reduce the number of parts by using pressure tension as a locking device for fastening latches and hooks and closing connecting passages. It is possible to maintain the same function even after long-term use by connecting the accessories without using a spring. The latch and hook respond organically to each other, making opening and closing smooth. The friction part is fine, so the same does not deform and maintains unchanged function even after long-term use. The connecting passage is not opened or closed arbitrarily by the latch link or by an external impact.

It will be understood that the present invention is not limited to the following examples, and various modifications may be made by those skilled in the art to which the present invention pertains.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a hook manufactured by the technique of the present invention. Referring to this, an arch-shaped hemispherical embossing 108 and an arcuate central multi-part 110 are located in the center of the plate spring-shaped hook as the body, and the A hook nose 101 and a hook 102 in the form of a ring are formed at the upper end, and a locking jaw 103 caught by a latch is formed at one end of the hook 102, and a locking hole 111 and a connecting passageway ( 100), left and right movement is possible in the latch, and left and right rails 109 and 110 are formed on the left and right sides of the hook body, respectively, and at the bottom of the body, ornamental joint holes 107 for connection with the ends of ornaments. By including the formed O-ring 106, the hook body and the O-ring 106 are narrowly connected to each other, including the twist point 105, the hook itself serves as a leaf spring.

Figure 2 is a front perspective view of a latch made of an oval pipe by applying the technology of the present invention, Figure 3 is a rear perspective view of the latch made by the technology of the present invention Figure 2, Figure 4 is a-a' of FIG. This is a front view of the cut lower surface as viewed from above. Referring to this, it is as follows.

The hook can be inserted in the form of a leaf spring, and the central part is an oval pipe-shaped latch in the form of a front round bending 209 and a rear round bending 215 in an arcuate shape. (210), a stopper 203 through which the hooking jaw 103 of the hook is hooked is formed, and a stop hole 205 to which the hemispherical embossing of the hook is finally coupled when the hook is vertically coupled is formed in the center, and left and right at the bottom thereof An anti-slip embossing 206 in the form of a long groove is formed, and the left and right sides are formed by a left V bending 214 and a right V bending 211, respectively, and an O-ring 106 of a hook is inserted and twisted at the bottom. As the bending 207 formed along the inner diameter along the hole 208 and the edge of the O-ring hole is formed, the latch itself functions as a torsion spring.

To reduce the number of parts and not use a spring, the latch made of an oval pipe is manufactured, and the manufacturing method of the latch is a folding method. The right side was formed by bending the obtuse V (V)-shaped bending 214, 211 with a dull bottom, and was produced only by folding the bolt made of an oval pipe with a complete shape.

The gentle round bendings 209 and 215 of the front and rear of the latch are formed by applying the same principle as a leaf spring, and the obtuse V-shaped bending 214 and 211 of the left and right sides of the bottom is obtuse. molded by applying the principle of The method of maintaining the pressure tension in the latch is in the manufacture of a bar made of an oval pipe without welding the bar, and the manufacture of the bar without welding can be completed with the cover 212 (refer to FIG. 3 ).

Figure 5 shows a state in which the connecting passage is open by the initial coupling of the latch and the hook and the hemispherical embossing is in contact with the semicircle round and the hook is stopped. It is divided into a part that passes through and protrudes out of the latch and a part that is not inserted into the inner diameter 201 permanently residing in the inner diameter 201 . The part that passes through the inner diameter 201 and protrudes out of the latch has an O-ring 106, and the part that resides in the inner diameter 201 is an arcuate central multi-part 110, hemispherical embossing 108, right rail 104, left rail 109, and The part that is not inserted into the inner diameter 201 is the locking hole 111, the locking member 102, the locking jaw 103, and the position of the locking jaw is the right rail among the left and right rails 109 and 104 residing in the inner diameter 201 of the latch. (104) By forming a jaw protruding as much as the thickness of the raw material of the latch on the upper side of the rail, the stopping jaw 103 and the stopping member 102 formed at the top are divided into parts that are not inserted by the inner diameter 201.

The height setting of the arcuate central multipart 110 formed on the hook is based on the width of the inner diameter 201 of the latch, and the apex of the arcuate central multipart 110 is molded to a height that does not touch the front round bending 209 inner diameter 201 wall of the latch. And a hemispherical embossing 108 was molded at the apex of the arcuate central multipart 110 . The degree to which the hemispherical embossing 108 molded at the apex of the arcuate central multi-part 110 within the inner diameter 201 of the bolt is fastened to the stop hole 205 is fastened to the stop hole 205 only above the seven ridge line of the hemispherical embossing 108. Therefore, when the hook is coupled to the latch, the hemispherical embossing 108 stimulates the latch, so that the latch responds as a spring in which the pressure tension is maintained.

The outer diameter of the O-ring 106 was molded to be twice the width of the inner diameter 201 . As for the coupling of the hook and the latch, when the latch is lowered in the same order as specified in the drawing based on the hook in FIG. 1 , the hook nose 101 and the latch nose 210 are directed in the same direction and in the same direction. When inserting from the O-ring 106 of the hook to the inner diameter 201 of the latch, the left and right rails 109 and 104 of the hook touch the inner diameter of the latch inner diameter 201 and left and right V-shaped bending 214, 211 and gently insert As the hemispherical embossing 108 touches the semicircular round 213 of the latch, the hook stops and the connection passage 100 is open, as shown in FIG. 5 (refer to FIG. 5).

6 shows that the connecting passage is closed by the complete combination of the latch and the hook, a locking hole is formed, the hemispherical embossing is fastened to the stop hole within the inner diameter of the latch, the locking jaw is caught on the stop, and the O-ring passes through the inner diameter and protrudes from the end of the O-ring hole As shown, referring to this, it is as follows. The parts in which the hook and the latch function organically include the latch nose 210, the hook nose 101, the O-ring hole 208, the O-ring 106, the stopping hole 205, the hemispherical embossing 108, the stopping jaw 203 and There is a locking jaw 103. In the O-ring hole 208 of the latch, the twist point 105 and the O-ring 106 reciprocate up and down in the O-ring hole 208 by the opening/closing operation of the connecting passage 100. . When the hook stopped at the inner diameter of the latch 201 is lightly pressed with the inner diameter of the latch 201, the hemispherical embossing 108 stopped by touching the semi-circle round 213 passes through the semi-circle round 213 and from the moment it is inserted into the inner diameter of the latch 201 Hook nose 101 is inserted into the inner diameter 201 of the latch nose 210 while the hook and the latch are organically interlocked with each other to maintain the increased pressure and tension in each part molded by the metal's elasticity and molding. As the connection passage 100 is closed, the hook 103 protruding from the upper side of the right rail 104 is caught by the stopper 203 and the hook stops, and the hemispherical embossing 108 stops within the inner diameter 201 of the latch. It is fastened to the hole 205, and all couplings are instantaneously made at the same time, and it becomes a latch link for closing the connection passage 100 as shown in FIG. 6 (refer to FIG. 6).

When combined as shown in FIG. 6 , the connecting passage 100 is closed to form a locking hole 111 , and the O-ring 106 passes the O-ring hole 208 and stops at the entrance of the lower O-ring hole 208 , and the twist point 105 . is stopped at the O-ring hole (208). When the coupling of FIG. 6 is performed, the hook portion protruding out of the latch is shown as the upper part of the latch is the latch 102, the latching hole 111, the latching jaw 103, and the O-ring 105 is the lower part of the latch.

6, the metal itself elasticity of the latch and the hook and the enhanced elasticity of each part molded by molding are gathered in the stop hole 205 of the latch and the hemispherical embossing 108 of the hook, so the fastening is very strong. Thus, the latch and the hook are an immovable latch locking device that closes the connecting passage 100 without moving forward and backward, left and right, up and down, and the connecting passage 100 does not open or close by external impact or arbitrarily with the latch hook.

7 shows the completed latch linkage by changing the angle to the O-ring by twisting the twist point so that only the O-ring is diagonal with the latch and the hook in FIG. 6, and FIG. This is a perspective view showing the opening of the latch connection passage where the hook is stopped by bending toward the inner diameter of the deep hole. Referring to this, it is as follows.

If the angle of the O-ring 106 is changed by twisting the twist point 105 so that only the O-ring 106 becomes a diagonal line with the latch and the hook when the connection passage 100 is closed, the latch connection ring that can be used directly for the ornament of FIG. 7 is completed. do. Only the O-ring 106 becomes diagonal with the latch and the hook, and the O-ring 106 that has passed the inner diameter 201 cannot enter the inner diameter 201 again, and the hook cannot permanently deviate from the inner diameter 201 of the latch. The hook trapped in the inner diameter of the latch 201 is the same as in FIG. 8 where the O-ring 106 is caught on the bending 207 toward the inner diameter of the O-ring hole 208 when the connection passage 100 is opened, and when the connection passage 100 is closed As shown in FIG. 7 where the stopping jaw 103 is caught by the stopping jaw 203, the hook resides in the inner diameter 201 of the latch and can only reciprocate up and down within the inner diameter 201 as much as the connecting passage 100 opens and closes. there will be When the connecting passage 100 opens and closes, the friction between each part molded on the latch and hook is also fine, so the operation of opening and closing is smooth. It is a strong, unshakable latch lock, and the connecting ring does not open or close the connecting passage 100 arbitrarily.

By forming the O-ring hole 208, the length of the hook and the latch can be shortened, so the entire length of the latch connection ring can be reduced and at the same time the connection passage 100 can be opened widely. The cover 212 is the connection passage 100. It also plays a role in controlling the limit of movement of each part molded to the latch when opening/closing. The anti-skid embossing 206 formed on the front and back sides of the round bending 209 and 215 of the latch prevents deformation of the front and rear round bending 209 and 215 of the latch, as well as the metal itself elastic and molded round bending 209 ) is also important for maintaining the elasticity of 215 . Bending 207 toward the inner diameter helps to prevent partial deformation by directly encountering the O-ring 106 when opening the connecting passage 100 and to prevent deformation of the front and rear round bending 209 and 215 and the entire latch. do. In the method of using the latch link, one end of the ornament is bound to the ornamental joint hole 107 and the other end is bound with an A-shaped bar to complete a wearable accessory.

When the hook is inserted into the inner diameter of the latch, the left and right rails are in close contact with the V-shaped bending inner diameter wall of the left and right obtuse angles of the latch, so that the left and right rails are formed to prevent tilting to the left and right.

The method in which the pressure and tension is maintained in the latch connection ring is a method using the constant elasticity of the arcuate central multiple part 110 molded in the center of the hook, and the hemispherical embossing 108 was molded at the apex of the arcuate central multiple part 110, and the hemispherical embossing was performed. From the moment it is inserted into the inner diameter of the latch, the latch reacts in the same way as a spring to continuously maintain pressure and tension on the latch link, and an arcuate central multipart is molded, and a hemispherical embossing is molded at the apex.

Among the parts molded on the hook, the locking jaw 103 is molded to determine the part that passes through the latch and protrudes out of the latch, the part that permanently resides in the inner diameter of the latch, and the part that is not inserted into the latch.

When the hemispherical embossing 108 is fastened to the stop hole at the inner diameter of the latch (see FIG. 6), the angle of the O-ring is changed so that the hook cannot be permanently deviated from the inner diameter of the latch.

The O-ring is manufactured by setting the size of the O-ring outer diameter based on the width of the inner diameter of the latch so that the outer diameter of the O-ring 106 is formed to be more than twice the width of the latch, and the angle of the O-ring is changed so that it cannot deviate from the inner diameter of the latch.

In addition, the height setting of the arcuate central multiple part 110 formed on the hook is molded to set the height at which the apex of the arcuate central multiple part does not touch the inner diameter wall based on the inner diameter width of the latch.

The hemispherical embossing is formed from the apex of the arcuate central multipart toward the stop hole so that the hemispherical embossing formed at the apex of the arcuate central multipart is fastened to the stop hole within the inner diameter of the latch. It is preferable that the degree of fastening in which the hemispherical embossing is fastened to the stop hole is fastened to the stop hole from the apex of the hemispherical embossing to only three parts of the hemisphere.

The embodiments presented above are exemplary, and those of ordinary skill in the art will be able to make various modifications and modifications to the presented embodiments without departing from the technical spirit of the present invention. The scope of the present invention is not limited by these variations and modifications.
