Description

  The present invention relates to a hanging method and a hanging tool for coating a metal cage when the metal cage is coated with a synthetic resin.

  Conventionally, a metal bowl used for tableware storage is coated with a synthetic resin to prevent a metal mark from adhering to the tableware to be stored and to prevent rusting. For example, if stainless steel is used as the metal, rusting can be prevented, but the metal mark cannot be prevented from adhering to the tableware. Therefore, a synthetic resin is coated to prevent the metal mark from adhering.

  Further, when a synthetic resin is coated on a conventional metal cage, the lower end of the suspension wire is welded to the bottom or side wire by making the metal cage downward or sideways.

Utility Model Registration No. 3077228 Japanese Patent No. 4157970

  Conventionally, a tableware bowl is made of metal and is coated with a synthetic resin in order to prevent the metal mark from adhering to the tableware. To coat a metal cage with a synthetic resin, the synthetic resin is attached to the metal wire constituting the metal cage, and when the cage is molded using this metal wire, a metal cage is made with the metal wire, and this metal wire However, since the former cannot weld each wire of the metal rod, most of the rods must first make a metal rod and then coat this with a synthetic resin. It has become normal. In order to support the metal cage during the synthetic resin coating, as shown in FIG. 3, a metal wire for suspension (hereinafter referred to as “suspending wire”) 10 is applied to the central portion of the metal wire 1 a at the bottom of the metal cage 1. The lower end of this is fixed by welding (FIG. 3B). When the coating is finished, the suspension line 10 is cut at B immediately above the welded portion 10a. However, the cut portion is exposed and there is a risk of injury if the hand is touched by mistake. Therefore, if the synthetic resin is applied to the cut surface, the risk is reduced. However, since the cut surface is sharp, the synthetic resin application is easy to tear and the section of the suspension line is easily exposed (synthetic Insufficient resin deposition) or the synthetic resin is peeled off, so that there is a risk of injury and rusting.

  This invention solves the above-mentioned problem by binding one end of the heat-resistant fiber to the metal wire at the bottom of the metal cage to be coated with the synthetic resin, and hooking the other end of the heat-resistant fiber to the hanging wire. It succeeded in doing. That is, even if the heat-resistant fiber is cut and the cut surface is exposed, there is no risk of injury or rusting when a finger or the like comes into contact with the portion.

  The fiber used in the above is required to have heat resistance to high temperatures (for example, 300 ° C. or more) and to have a strength capable of withstanding a hanging load. The material of the heat resistant fiber is a heat resistant synthetic resin “for example, poly (paraphenylene benzobisoxazole)” or carbon fiber of 300 ° C. or higher. For example, the fiber is 8th and needs to have a tensile strength of 10 kg or more, and is preferably made of a material that does not lose its tension even at high temperatures (300 ° C. to 400 ° C.).

  One end portions of the two heat-resistant fibers are bound at intervals of 2 cm to 4 cm, and the other end portion is hooked to both end hook portions of a single fine metal wire (for example, a diameter of 0.1 mm). The central portion of the thin metal wire is hung on a hook portion of a suspension line (diameter: 1 mm to 2 mm).

  The number of heat resistant fibers in the above may be one if they are 8th, but two are preferable because two are more stable. There is no need to use three. Further, it is conceivable to omit the fine metal wire and directly hook one end of the heat-resistant fiber to the hook portion of the hanging wire. However, in this case, the stability is likely to deteriorate, so it is preferable to interpose the fine metal wire. .

  The method for coating the metal cage as described above is to suspend and move the metal cage, spray a coating solution during the movement, or raise the metal cage to a high temperature (for example, 200 ° C. to 300 ° C.) and apply a heat resistant coating material thereto. Known methods such as spraying polyester (eg, polyester, polypropylene, zenitylene chloride, polycarbonate, or heat-resistant nylon resin) or dipping a metal cage in a heat-resistant coating solution are used, but in any case, the metal cage is suspended. And you have to move this.

  In the above, the heat-resistant coating material is often used as a metal bowl as a tableware bowl, but in this case, it is often in contact with hot air of 100 ° C. or more for a long time when washing and drying the dish. Since it sometimes exceeds 150 ° C., it must be made of a material that does not change (soften or dissolve) the coating material even when exposed to 100 ° C. to 200 ° C. for a long time.

  The first object of the present invention is to prevent a part of the used hanging tool from remaining on the side of the metal cage after coating the metal cage in a suspended state. Is the biggest purpose. Therefore, a material that does not cause any trouble even if it remains is obtained. Although there are relatively many heat-resistant fibers that can withstand 200 ° C., it has been found that there are many cases where they are exposed to a high temperature of 200 ° C. or more and nearly 300 ° C. depending on the use of the metal cage. In some cases, heat-resistant fibers that exhibit sufficient strength (tensile strength) are required.

  In the present invention, one end of a string made of heat-resistant fiber is fixed to the bottom line of the metal rod at two, three or four points at predetermined intervals, and the other end of the string is attached to the lower end of the hanging line of the metal rod. A method for suspending a metal cage characterized by being hooked, wherein one end of each of two cords made of heat-resistant fibers is fixed to a wire at the bottom of the metal cage at a predetermined interval, and the two cords The metal rod hanging method is characterized in that the other end of the metal wire is hooked to both ends of the metal thin wire, and the center portion of the metal thin wire and the lower end portion of the hanging wire of the metal rod are hooked. .

  3. The method of suspending a metal cage according to claim 2, wherein hooks are formed at both ends of the thin metal wire, and the other ends of the two strings are respectively hooked on the hooks. 3. The method of suspending a metal cage according to claim 1 or 2, wherein the formed string is linear or ring-shaped, and the heat resistant fiber is polyparaphenylene benzobisoxazole or carbon fiber. The method of suspending a metal cage according to claim 1 or 2.

  Furthermore, the heat-resistant fiber is a string of a predetermined length or a ring-shaped string, the metal rod hanging method according to claim 1, wherein one end is fixed to the metal rod, The hanging tool for use in the method according to claim 1, characterized in that it comprises a hanging line for hooking the other end of the string, and one end is fixed to the bottom line of the metal rod at a predetermined interval and the other end is made of metal. 3. A hanger for use in a method according to claim 2, wherein two cords made of heat-resistant fibers respectively hooked at both ends of the thin wire, and the metal thin wire and a hanging wire for hanging the metal thin wire are combined. It is.

  As described above, the gist of the present invention is that a heat-resistant string is interposed between the metal cage and the suspension line. Conventionally, the hanging wire was welded to the metal wire at the bottom of the metal rod, so that when the hanging wire was cut after coating, the cut end was sharp and there was a risk of injury when the finger touched. Further, even if the cut surface is coated, it may be easily peeled off and rusting may occur, and there is a risk that a finger may be injured by a part of the cut edge even if the cut surface is not peeled off. Various countermeasures have been taken for the conventional problems, but none of them are perfect.

  However, the use of heat-resistant fibers or their strings has eliminated the sharp edges and succeeded in preventing injury.

  In the above, the presence of the fine metal wire improves the stability when suspended and moved. In the above, the object can be achieved only by the string and the suspension line, but in this case, the string becomes long and easily becomes unstable. Therefore, a thin metal wire was interposed between the suspension line and the string, and the string was shortened to ensure stability.

  According to the present invention, since the heat-resistant fiber or the heat-resistant string is interposed between the hanging wire and the metal rod, there is no danger when the hanging tool is removed after coating the metal rod, and the appearance is damaged. There is an effect without fear (for example, by rusting).

  In addition, since the fine metal wire is interposed between the suspension line and the heat-resistant string, the length of the heat-resistant string becomes as short as possible, and there is an effect that the stability is good and the control is easy.

  By the method of the present invention, it is possible to prevent the danger that has been a drawback of the conventional coating wrinkles.

  The string is very easy to attach and cut and has good workability.

(A) The perspective view which shows an example of the use condition of the conventional metal rod and a hanging line, (b) The cross-sectional enlarged view which similarly shows the welding state of a hanging line.

  In the present invention, one end of each of two heat-resistant cords is tied to the center of a line (for example, the bracing line 1a in FIG. 1) that forms the bottom of a metal cage to be coated with a synthetic resin. Hang the other end of the tie to the hooks on both ends of the convex fine metal wire, and hook the hook provided at the lower end of the suspension wire to the center of the fine metal wire. Be suspended. In the above, the string is made as short as possible (for example, 10 mm to 30 mm). In the above description, the reason for shortening the string is to reduce the degree of freedom of movement of the metal cage (the same applies to the shaking). The reason why the metal thin wire (with shape retaining property) is interposed is to facilitate the control of the posture of the metal rod (to reduce the degree of freedom).

  The first object of the present invention is to suspend a metal cage safely, reduce the fluctuation during movement, and achieve the purpose of suspending without trouble. Moreover, it is for preventing the harm by cutting a suspension line. In addition, as long as there is little harm due to the cutting of the suspending line, it is easy to control the posture of the metal rod as in the conventional welding of the lower end of the suspending line. Therefore, what remains in the metal cage is a heat-resistant fiber or a string made of the fiber. In this case, if the string is removed, the resin coating of the string binding part is peeled off, so that the string binding part is left as it is, but since the string material is heat-resistant fiber, even if a part of the string remains, there is no danger. There is no risk of it occurring. However, in the case of a string, the degree of freedom of movement of the metal cage increases. Therefore, in order to shorten the length of the string as much as possible, it is preferable to interpose a fine metal wire. Even when the string is hooked directly on the hanging line, it can be adopted if the hanging part of the hanging line is improved and can be hooked directly with a short string (for example, 3 cm to 5 cm).

  An embodiment of the present invention will be described with reference to FIGS. A string 2 which is a ring with one end tied to the bracing line 1a at the bottom of the metal rod 1 is bound. In this case, the endless side (U-shaped portion 2a) of the two cords 2 is wound around the bracing line 1a, the knot 2b side of the cord 2 is passed through the U-shaped portion 2a, and the knot 2b is indicated by the arrow 7 By pulling in this way, the U-shaped portion 2a of the string 2 can be tied to the bracing line 1a.

  Next, the thin metal wire 3 formed in a triangular convex shape is inserted, and the knot 2b of the string 2 and the hook portion 3a of the fine metal wire 3 are hooked. Although the metal thin wire 3 has a diameter of 0.1 mm to 0.2 mm, the metal wire 3 has high rigidity, so that the convex shape can be maintained even when the metal rod 1 is suspended. A hook portion 5 a of a metal suspension wire 5 is hooked on the central portion 3 b of the thin metal wire 3.

  If the metal rod 1 is suspended in a normal manner and coated with synthetic resin, the binding portion between the bracing line 1a and the string 2 is also covered with the synthetic resin layer 9 (FIG. 1 (c)). Therefore, when the cord 2 is cut at the point A, the cut surface of the cord is flush with the synthetic resin layer 9.

  Even if the cut surface of the string is exposed, there is no risk of damaging a finger or the like, which is safe. Moreover, since the string is hardly conspicuous in appearance, there is no possibility of deteriorating the quality of the metal cage. Moreover, a synthetic resin may be attached to the cut surface of the string just in case.

  As shown in FIGS. 2 (a) and 2 (b), the string used in the above is endless (FIG. 2 (b)), a ring having a binding portion (FIG. 2 (a)), or a U-shape (FIG. 2 (2)). c)). FIG.2 (d) in the above is explanatory drawing when a string is tied to the bracing line 1a.

  In the above embodiment, the string 2, the fine metal wire 3 and the hanging wire 5 can be mass-produced in advance, and the hooking of the string 2 and the fine metal wire 3 is very simple and can be attached in a short time. (Human power) There is no risk of hindrance.

  Although the said Example demonstrated the string 2, a fiber can be cut | disconnected to predetermined length and can also be used as it is. Although there are various methods for manufacturing the string 2, for example, a plurality of fibers can be welded to form a single string. If both ends of one fiber are welded, an endless ring-shaped string can be formed.

  FIG. 2E, in which both ends of a single string are tied to the bracing line 1a at a predetermined interval, is an embodiment in which the string 2 is directly hooked on the suspension line 3. Also in this embodiment, it is possible to eliminate the problem of exposing the cut portion of the metal wire as in the prior art. However, in the case of this embodiment, since the string is hooked directly on the suspension line, the string is inevitably long, the swing of the suspended metal fence is slightly increased, or the control accuracy of the attitude control of the metal fence is high. There is a problem such as lowering, but there is no problem when the attitude control of the metal rod is not required.

  Another embodiment of the suspension method of the present invention will be described with reference to FIGS. 2 (f) and 2 (g). FIG. 2 (f) shows a case in which one end of one string 4 is fixed to the wire 1a and 1b of the metal cage, and one end of one string 2 is fixed to the line 1a (by winding or binding). The central part of the string 4 is hooked to the hook 5a of the suspension line 5, the other end of the other string 2 is hooked to the hook 5a, and the metal hook is attached to the two strings 2, 4 It is suspended. According to the embodiment, since the heel is supported at three points, the stability is better than that at the two-point support.

  Next, another embodiment will be described with reference to FIG. The ends of the two cords 2 and 4 are tied to the line 1a at a predetermined interval, and the other ends of the cords 2 and 4 are tied to the line 1b at a predetermined interval. It is hooked on the hook 5a of the suspension line 5. In this case, the metal cage is supported at four points and has good stability and easy posture control.

  In the case of the three-point support and the four-point support in the above embodiment, the fine metal wires are not interposed, but the fine metal wires can be interposed between the hook 5a and each string. That is, the object can be achieved by hooking each string to the hook of the fine metal wire and hooking the central portion of the fine metal wire to the hook of the hanging wire.

  As described above, there are two-point support, three-point support, and four-point support for the method of hanging the metal cage, and each is selected and used according to the conditions of the metal cage (size, shape or weight of the metal cage). Since there is no need for point support, two to four point support is practically used.
