Abstract

The present invention solves the deformation of the expansion and contraction caused by heat by making the outer periphery seat of the fan have elasticity by heating and pressing the fan paper coated with the heat-sealing synthetic resin film on both sides of the synthetic resin fan. It is about a fan with a flexible seat frame adapted to the.

Conventionally, after a combination of thermoplast and fan paper made of a synthetic resin fan and hot-bonded, and cut in the shape of a fan, a sharp cut surface is generated at the end of the outer periphery, or left to stand, or in order to prevent this, each of the fan rods The outer periphery frame connecting the ends of the joints was formed, and the same size of fan paper was matched with each other on both sides and heated and pressed, but they were radial lines distributed vertically in proportion to the shape, length, and volume of the fan rods. And the shrinkage expansion rate of the horizontal line is significantly higher than the shrinkage expansion rate of the fan paper, and the fan paper and the expanded fan rod and the outer frame which are fused by the heat of 140 ° C. or higher applied for 3 to 4 seconds during the adhesive processing are There is a disadvantage in that the shrinkage of the fan and the plate surface of the fan is transformed into a similar dish shape.

In order to solve this drawback, the present invention is to devise a fan to form a safety frame rich in elasticity in the shape of a separate toy pattern for each unit.

Description

Elastic seat frame fan

The present invention combines a fan paper coated with a heat-adhesive synthetic resin film on both sides of a fan meat on both sides of the fan meat and heat-presses it with a heating press to have the shape and elasticity of a beautiful pattern of the outer frame of the fan to be bonded and processed. In order to prevent deformation of the fan due to contraction and expansion that occurs, it relates to a fan that forms a flexible outer perimeter safety frame adapted to the environment.

Fans using conventional synthetic resin fan have a risk of sharp edges on the outer periphery of the fan by hot-bonding fan paper to synthetic fan and then cutting it into the shape of a fan.

Large quantities of waste that are well disposed of and disposed of, raw material loss, manufacturing costs and manufacturing processes are profoundly flawed. In addition, the Japanese Patent Office (JP) Utility Model Publication (Y2) No. 56-11775 (published on March 17, 1981) to solve these defects, as shown in Figure 4, the end of each fan rod radially formed in the rod as shown in FIG. In the synthetic resin fan with the outer frame of the same shape and size of the fan to be completed, a plurality of cross sections connecting the front and rear surfaces of the fan strips are formed to form a gap between the fan strips and the cross sections. It forms a square and rectangular recessed space with a narrow mesh shape, and at the same time, the fault rods and the cross sections are overlapped with each other by the thickness of the fan rods and the cross sections. Using

Even if two sheets of adhesive paper coated with adhesive on one side are joined together at the front and rear sides of the fan, they are bound only on the smooth surface of the fan rods and the cross sections, and the mesh shape is formed between the front and rear fan sheets. It is possible to prevent the plate surface of the fan paper from spreading in a wave shape while being refracted by the surrounding moisture during drying or use of the adhesive during the manufacturing process, by preventing the adhesion of the spaces to be formed. To maximize the life of the fan and the aesthetics of the outsourcing safety frame that is laid out, this is due to the fact that there is a significant difference in the rate of shrinkage expansion and shrinkage that occurs frequently depending on the temperature of the surrounding environment. As it is a state,

Synthetic scaffolds and transverse tubes and high outer rims of shrinkage and expansion at high rates are unsynchronized with fan paper that shrinks and expands at low rates and curvature of outer rims, scaffolds and transverses are shrunk and shortened. It is refracted in the shape of and has a defect that the weak adhesive parts fall or the entire plate surface of the fan is deformed into a dish shape.

Japanese Patent Office (JP) Utility Model Publication (Y2) No. 59-8583 (published on March 3, 16, 1984), which was devised to solve the above problems, is 3 ^m above the fan-shaped specification to be completed as shown in FIG. radially shape fanfolds reduced by ^{/ m} to ^{5m / m} , and form an outer perimeter that connects the ends of them to each other, and inject the fantail into the synthetic resin material to maintain a constant gap between the fanstands until bonding. After molding

A pressure-sensitive adhesive, and fusing or the like a fan paper two sheets coated on one side from the outer circumferential rim that is bonded to each other matches in all the chuck steak, after both surfaces are jeopjak buried between fan paper 3 ^{m / m} to about 5 ^{m / m} outskirts By forming the shape of the fan to be completed by cutting the shape, the attempt is made to solve the problem that deformation occurs due to the mesh shape is created by the shape of the transverse as described above, but this is compared to the above-described design. The extreme deformation of the entire plate is reduced, but the method of contraction and expansion of the outer rims connected in a row and connected with the fan rods buried at the top is overlooked. Not only does the disadvantage remain, but the sharp outer end formed by only the fan tray which is cut and left after adhesion is dangerous to the human body. , There is a disadvantage of a short life debt.

In the Japanese Patent Office (JP) Utility Model Publication (Y2) No. 59-8584 (published on March 3, 16, 1984), which was devised to solve the problem of refractive deformation due to shrinkage expansion as described above, as shown in FIG. To extend the length of the fan rods 5 ^{m / m} to 8 ^{m / m} than the fan shape specifications to complete, to prevent deformation of the fan rods until the bonding operation, and to maintain a constant gap After the injection molding of the scallops with the outer rims connected to each other by synthetic resin material,

A heat-sealable synthetic resin film on one surface coating (coating) hameuroseo a fan media two to the to each other matches in all the chuck steak, after two-sided hot-press with high temperature high pressure during momentary short time of around three seconds the adhesive, 0.03 ^{m /} Heat-sealable synthetic resin coated on fan paper without the influence of heat conduction on fan rods that require a large amount of heat of dissipation because the unit volume is large in proportion to the film of heat-sealed synthetic resin coated with a thickness of less than ^m Melt only the film and glue the fan paper on the front and back to separate the fan rods buried between the fan paper to cut it into the shape of the fan to be completed, and then apply the adhesive to the outer end of the sharply cut fan. Folding a piece of earth to form a frame of debt, in isolation from the fan paper as in Japanese Patent Office Utility Model Publication No. 61-66517. When the buried rods are expanded and contracted by the temperature which varies from time to time depending on the surrounding environment, the extreme deformation of the entire face plate of the fan is reduced, but the fan rods are inflated and the sharply cut ends protrude out of the outer end of the fan paper. It is dangerous and attempts to solve the defects such as the debt papers between the outer and outer ends of the debt, which are broken or damaged. Since the edges of the outer periphery formed by the binding are blocked, the width of the fan rods is gradually enlarged to create the play, but the contraction of the radial rods distributed radially is maintained while maintaining the inclination angle of about 10 °. The surface of the fan to be smooth, not reaching the sequestration space required by expansion. And a rim of a defect of deformation, formed in the outer peripheral land liability also there is a defect can not completely eliminate the wave, galling phenomenon of the fan end.

In addition, the Japanese Patent Office (JP) Utility Model Publication (Y2) Hei 2-32089 (announced on August 30, 1990) shows that the ends of the fan rods have the same size as the shape of the fan to be completed in the injection mold of the fan blade as shown in FIG. After excavating the outer frame to connect, cut the fan paper into the shape of the fan to be completed, insert each into the sculpted surface of the front and rear injection mold, and injection molding the synthetic resin material, without the additional bonding process, etc. Although it is directed to produce a complete fan with a temporary fan, this is forcedly reduced to a state in which the fan joint melt-injected at the melting point of the resinous resin material is contracted with a fan paper having a significantly low expansion shrinkage in the process of cooling and shrinking in the air. There are great disadvantages, such as the sheet being deformed in all directions.

In addition, Korea Patent Application Utility Model Registration No. 098471 (July 30, 1886) is a debt to be completed by forming a line of outer periphery frame formed integrally with the buried protrusion connecting the ends of the synthetic resin fan rods as shown in FIG. Formed into the shape of a plate, two sheets of fan paper coated with a fused synthetic resin film on one side are cut to the same size as the shape of the inner edge of the outer rim, and matched with each other on both sides before and after the heat of the fan, Therefore, the buried frame portion buried between the fan papers is not attached to the fan paper because the heat during the instantaneous thermocompression bonding process does not reach the temperature to melt the buried frame, so it is separated and adhered to the fan paper. Although it is intended to prevent the deformation of the plate, this is because the volume of the outer frame that is integrally connected with the buried frame, Since the entire outer periphery of the fan is formed as a continuous line with no cut parts connected to the ends of the, the length of the outer periphery shortens as the length of the outer periphery decreases, and the deformation is reduced. As well as

Fans that are heated at the same time between the process of fusing and bonding the heat-sealable synthetic resin film coated on fan paper with a high temperature of over 140 ° C and a pressure of 800 ^KG / 500 ^CM2 cannot reach the melting temperature of around 170 ° C. The approximate actual inflation length immediately after heating of each of the longest fan rods of the various resin fan beams that are commonly practiced in the range of about 3 ^{M / M} is 2 ^{M / M} depending on the heating temperature and heating time. At the time of thermocompression bonding, the fan strip is bonded while the fan strips are already inflated. As each fan strip is expanded and contracted, it is contracted and reduced to form a unit with a large outer frame and connected to the fan strips. The buried frame is drawn into the center of the fan plate, and the length of the contraction and the unit volume The buried frame itself, which is formed integrally with the outer rim, is shortened and its circumference is shortened, and the buried frame moved to the center by the diameter of the rim is bonded to the fan paper at the position to be preserved. There is a defect that becomes a factor that deforms the entire plate surface of the fan into a dish shape loses room to move in the cooling shrinkage process.

The present invention forms a flexible safety frame, which is formed for the sake of safety when using a fan, and prolongs aesthetics and aesthetics, in a shape of a flexible ball, and deforms the plane of the fan under the influence of heat shrinkage expansion. While minimizing the phenomenon, it does not artificially restrain the phenomenon of contraction and expansion, which is inevitably caused by the surrounding environment, and conversely, by adapting to it, the elastic safety frame of the fan is frequently deformed, but does not deform the plane of the fan. According to the rate of contraction and expansion, the elastic safety frame divided into the shape of the toy pattern is refracted to the outer periphery of the fan outer periphery, so that a variety of finely deformed patterns are produced.

Referring to the configuration and operation based on the accompanying drawings as follows.

The thickness is the same as the outer periphery of the fan surface to be completed, starting from the left and right sides of the shaft 2 of the handle 1 and connected to each other at the center of the upper end and having a thickness of 0.8 at the outermost top. Since the space between the elastic safety frame (4) of m / m and width 3 m / m and the elastic safety frame (4) formed above is narrowed by laying it below 1m / m from the lower end thereof, the front and rear fan paper ( 8) Form a stretch frame (5) with a diameter of 0.5 m / m, which is buried between fan papers at the outer periphery end, which cannot be bonded to each other, and acts as a stretch mechanism, and lay it below 2m / m from the bottom of it. Fan paper on the front and rear sides by widening the space with the new stretched frame (5) by the heat pressure of the heat-resistant silicone rubber plate of about 30 ° C and 30 degrees of hardness attached to the heat transfer plate of 800 ^KG / 500 ^CM2 pressure Is refractively matched and adhered to the outer periphery Three-wire ball pattern with flexible edges formed by three rows of lines, such as a buried frame (6) with a diameter of 0.6 m / m that is embedded and supports the outer peripheral end of the fan paper ( 2-wire toy pattern with flexible edges that form a simple line or form a stretch frame (5) in two lines. After having formed the outer periphery as a shape-rich, elastic structure, the elastic safety frame (4) formed at the outermost part through the space formed between individual armbands from the slide (2) at the top of the handle (1) and After forming the fan shafts (3) to be connected, and injection molding the fan blades formed with the screen printing section (9) on the shaft (2), and the fan hanger (10) in the center of the top surface of the fan fan formed of synthetic resin material ,

Two sheets of fan paper (8) coated with a film or adhesive coated with heat-bonded synthetic resin are cut to a size smaller than the shape of the stretchable safety frame (4). To bond

As a function of the present invention configured as described above, the fan rod 3 and the fan paper 8 are combined and mounted on a heating pressurizer, and then thermally pressed for 3 to 4 seconds at a high heat of 140 ° C. or higher and 800 ^KG / 500 ^CM2 pressure. During the process of fusing the heat-sealed synthetic resin film coated on the fan paper (8), the fan rods (3), the stretchable safety frame (4), the stretch frame (5), and the buried frame (6) are around 170 ° C. The melt temperature is not reached, but is inflated by 1% to 2% in the direction of formation, depending on the length, unit volume and shape, and then the actual occurrence between the normal operations of the synthetic fan blades of other shapes (up to now implemented). )

In the process of taking out from the gluer and cooling in the air, all the scaffolds (3) have a large volume of the bow (2) to which the lower end is connected, so that the specific gravity of the bending strength is high, so that the contraction is contracted downward to the vertical line and the lower upper part is connected. The elastic safety frame (4) of bending strength is drawn in, and the elastic safety frame (4) of the shape of a toy pattern formed for each unit of an independent shape is a refractive groove ( (7) refraction Since it does not affect the fan paper (8), it does not deform the face plate of the fan because it synchronizes with the shrinkage of the fan rods (3), and the buried frame (6) at this time is buried between the bonded fan paper (8). Although the phenomenon of contraction and expansion cannot be digested by itself, the buried frame (6) and the elastic safety frame (4) are reduced in length due to the phenomenon of contraction and expansion, and the elastic safety frame (4) is changed even if the positions of the left and right ends are changed. The connecting rod 11, which is the shape of the lowest bending strength, with the smallest diameter of 0.5m / m connecting the and the buried frame 6, is flexibly absorbed and absorbed, so that the vertical motion and the elasticity of the scaffolds 3 are Only the refraction movement of the safety frames 4 does not disturb the shape of the original toy pattern or deform the fan surface, and the screen printing unit 9 on the top of the rod 2 allows the fan to be randomly made to meet the demand of the consumer. To print at a low cost, Fan hanger (10) in the center of the top end is to hang the calligraphy of the fan for indoor decoration.

There is no risk of injury to the human body when using the adhesive frame or the elastic safety frame of such a structure, and the fully patterned elastic safety frame of the separate shape by unit allows the flat surface of the fan to bend flexibly. While the air volume is soft, the running feel is soft, and the contraction and expansion of the inevitable shrinkage and the angle of refraction are inevitably changed according to the high and low of the ambient temperature.

The simple shape of the fan outsourcing is a fine but diverse pattern to create a new feeling all the time, the fan hanger at the top to decorate the calligraphy of the fan correctly, and a small amount of demand for the low-season debt using the screen printing unit There is an effect that the screen printing can be done quickly and inexpensively any mutual etc.
