Abstract

The present invention solves the deformation of shrinkage expansion caused by heat by making the outer perimeter safety frame of the fan that is bonded by heating and press bonding the fan paper coated with the heat-adhesive synthetic resin film on both sides of the synthetic resin fan. The present invention relates to a fan with a flexible seat frame adapted to the environment. Conventionally, after a combination of hot and synthetic adhesive fan fan and fan paper, the cutting edge in the shape of the fan by cutting the shape of the fan is generated and left to stand, or to prevent it, each of the fan rods in the shape of the fan to be completed They formed outer perimeters connecting the ends of them and bonded them by heating and pressing the same sized fan paper on both sides, but they were vertical lines proportional to the shape, length, and volume of radially distributed fan rods. ) And the horizontal expansion rate of the horizontal line is significantly higher than that 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 at the time of bonding processing. There is a disadvantage in that the cooling shrinkage in the fan plate is deformed like a plate shape.

The present invention is to solve the drawbacks, to devise a fan to form a safety belt rich in elasticity of the shape of the individual ball pattern for each unit.

Description

Elastic seat frame fan

The present invention combines the fan paper coated with the melt-bonded synthetic resin film on both sides of the fan meat by heat-pressing with a heat pressurizer to have the shape and elasticity of the pattern of the beautiful outer frame of the fan to be glued and processed by heat, In order to prevent deformation of the fan due to shrinkage and expansion that occurs, the present invention relates to a fan forming a flexible outer peripheral frame adapted to the environment.

Fans using conventional synthetic fan blades have a risk of generating a sharp cutting surface at the outer periphery of the fan by hot-bonding fan paper to synthetic fan blades, cutting them into the shape of a fan, and waste that is cut and disposed of. Large quantities of raw materials, loss of raw materials, manufacturing costs and manufacturing processes are profoundly flawed. In addition, the Japanese Patent Office (JP) Utility Model Publication (Y2) No. 56-11775 (announced on March 31, 1981) to solve these defects, as shown in Figure 4, the end of each fan rod radially formed in the rod A gap between the fan rods and the rail rods is formed by forming a plurality of cross sections connecting the front and rear surfaces of the fan rods on the synthetic resin fan rods having the same outer frame as the shape and size of the fan to be completed. The narrow square and rectangular recessed spaces are formed, and at the same time, the cross sections are formed by the thickness of the cross sections and the cross sections between the cross sections and the cross sections. Using a single layer, even if two sheets of adhesive paper coated with an adhesive on one side are bonded together at the front and rear sides of the fan blade, the flatness of the fan rods and the cross sections is applied. It binds only to the active surface and prevents contact with each other by forming net-shaped spaces between the front and rear fan papers. By preventing the deformation of the surface into a wave shape, it is to maximize the advantages of the outer perimeter safety frame, which is formed for long-term fan life and aesthetics. Since the fan blade and the fan paper of the synthetic resin which have a significant difference in the ratio are bound to each other, the fan strips and the transverse tubes and the outer frame of the synthetic resin that contract and expand at a high rate, The outer frame, fan rods, and transverse sections, which cannot be tuned and are shrunk and shortened, are curved. There is a defect that the refraction and weak adhesive parts fall or the entire plate surface of the fan is deformed into a dish shape.

In Japanese Patent Office (JP) Utility Model Publication (Y2) No. 59-8583 (published on March 13, 1984), which was devised to solve the above problems, it is 3 ^{m / m} than the standard of the fan shape to be completed as shown in FIG. Radially shape the fan rods reduced by 5 ^{m / m} , and form the outer frame connecting the ends of them to each other, and injection molding the fan blades with a synthetic resin material to maintain a constant interval of the fan rods until the bonding operation. After that, two sheets of fan paper coated with one side of the adhesive and the adhesive, etc. are bonded to each other on both sides of the front and rear sides of the fan meat and bonded together, and 3 ^{m / m} to 5 ^m from the outer periphery bonded between the fan papers. ^{/ m} hameuroseo forming the shape of the fan to be completed by cutting the outside, is a mesh size (網目) shape created by hyeongseol the lateral span, as described above. However attempts to solve the problem of deformation is generated, the Compared to the above-described design, the extreme deformation occurring in the entire surface of the fan is reduced, but the method of contraction and expansion of the outer periphery frame connected with the fan rods attached to the uppermost part and overlooked is also overlooked. Not only the disadvantage that the outer periphery of the wave is refracted to remain, but the sharp outer end formed of the buoyancy that is cut and left after adhesion has the disadvantages to the human body and short life of the fan. In the Japanese Patent Office (JP) Utility Model Publication (Y2) No. 59-8584 (announced on March 16, 1984), which was devised to solve the problem of refractive deformation caused by shrinkage expansion as described above, ^{3m / m} to 5 ^{m / m} of fan rods are extended from the fan-shaped standard to prevent the deformation of the fan rods until the bonding operation, and the outer periphery connecting the ends of the fan rods to each other to maintain a constant gap. After the injection molding of the fan-shape with the synthetic resin material, two fan papers coated (coated) with one or more non-adhesive synthetic resin films were put together on both sides before and after the fan-shape and were heated at high pressure under 3 seconds. Part that requires a lot of heat of fusion due to the large unit volume in proportion to the film of heat-sealing synthetic resin coated with a thickness of less than 0.03 ^{m / m} by hot pressure bonding for a short time. The shape of the fan to be completed by melting only the heat sink synthetic film coated on the fan paper and bonding the fan paper on the front and the back to isolate the fan rods embedded between the fan paper without affecting the heat conduction. After cutting to form the edge of the fan by gluing the earth with the adhesive applied to the outer circumferential end of the sharply cut fan, and the fan paper as in Japanese Patent Office Utility Model Publication No. 61-66517 If the insulated bubbling rods are inflated due to temperature fluctuating from time to time depending on the surrounding environment, the extreme deformation of the entire face plate of the fan is reduced, but the ends of the fan rods are expanded and sharply cut out of the outer edge of the fan paper. The parts are protruding and dangerous, and the debt paper between the outer and outer ends of the fan is broken and damaged. However, this is because the edges of the outer periphery formed by binding the fan paper and the land block the expansion path of the ends where the radially shaped fan rods expand and protrude, so the width of the fan rods is gradually expanded. There is a defect that deforms the flat surface of the fan to be smooth, but maintains the angle of inclination of around 10 ° each other and does not reach the isolation space required by the contraction expansion of radially distributed fan rods. In addition, the edge of the debt outer periphery formed by the land has a drawback that does not completely solve the wave and wear and tear at the end of the debt.

In addition, JP Utility Model Publication (Y2) Hei 2-32089 (August 30, 1990) states 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 and forming the outer frame to be connected, the fan paper is cut out and inserted into the carved surface of the front and rear injection mold, and the injection molding of the synthetic resin material is carried out. Although it is directed to produce a complete fan with a temporary fan, this is forcedly reduced to a state in which it is forced to shrink with the fan paper which has a significantly low expansion and shrinkage rate in the process of cooling and shrinking the fan blade melt-injected at 170 ° C of the synthetic resin material. There are great disadvantages, such as the refractive deformation in all directions.

Also, Utility Model Registration No. 098471 (July 30, 1886) of Korea Patent Office completed the construction of a fan formed by forming a line in the form of a line of outer periphery formed integrally with the buried protrusions connecting the ends of the synthetic resin fan rods as shown in FIG. Forming the shape of the plate and cutting two sheets of fan paper coated with fused synthetic resin film on one side to the same size as the shape of the inner edge of the outer frame, and matching them on both sides before and after the fan blades Therefore, the buried frame portion buried between the fan paper is heat-bonded during the instantaneous thermocompression bonding process so that it does not reach the temperature to melt the buried frame and is not adhered to the fan paper. While it is intended to prevent the deformation of the debt surface, this is because the volume of the outsourcing frame that is integrally connected with the buried frame is large. 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. In addition, the heat sinks that are heated simultaneously between the processes of fusion bonding and bonding the heat-sealing synthetic resin film coated on the fan paper with a high temperature of 140 ° C. and a pressure of 800 ^KG / 500 ^CM2 do not reach the melting temperature of around 170 ° C. However, the approximate actual inflation length immediately after the heating of each of the longest fan rods of the various synthetic fan rods of the various synthetic fan rods, which have been widely distributed so far, is about 1.53 ^{m / m} depending on the heating temperature and heating time. from 2 ^{m / m} is exceeded, and so, at the time of hot-press bonding chuck steak teenagers are already expanded state in relation to which fan the paper is adhesive, As each of the fan beams that have been inflated are contracted and reduced, the unit frame is formed integrally with the large outer frame and draws the buried frame connected to the fan beams to the center of the fan plate. Due to the contraction of the buried frame itself formed integrally with the large outer frame, the buried frame moved to the center by the diameter that is shortened due to its shrinking diameter is bonded to the fan paper at the position to be preserved, not bonded for fixing. There is a defect that causes the entire plate surface of the fan to be deformed into a dish shape, losing room to move in the process of being taken out and cooled and shrunk.

The present invention forms a flexible safety frame formed in the shape of a flexible, soft-ball pattern for long life and aesthetics when using a fan, and deforms the plane of the fan under the influence of heat shrinkage expansion. On the other hand, it does not artificially restrain the phenomenon of contraction and expansion that is inevitably caused by the surrounding environment, and conversely, it adapts to the contraction of the fan and the contraction without deforming the plane of the fan According to the ratio of expansion, the elastic safety frame divided into a toy pattern is refracted to the outer periphery of the fan outer per unit, 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 circumference of the fan plate 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 top. The front and rear fan paper (8) has a narrow gap between the flexible safety frame (4) of m / m and width 3m / m and the flexible safety frame (4) formed above by forming below 1m / m from the lower end thereof. ) The elastic frame (5) having a diameter of 0.5m / m, which is embedded between the fan papers at the outer circumference end of which is not bonded to each other, serves as a stretch mechanism, and is formed below 2m / m from the lower end thereof and stretched above. Widening the space with the frame (5), the front and rear fan paper (8) bends due to the high temperature of about 140 ℃ and the heat pressure of heat-resistant sealing silicone rubber around 30 degrees of hardness attached to the heat transfer plate at 800 ^NG / 500 ^CM2 pressure. To the outer periphery of the mating 3 is seonsin balls pattern of the flexible edge is laid, such as Te (6) with a diameter of 0.6m / m for supporting the outer circumferential end portion of the paper fan (8), formed by the three line-line ( 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 unit 90 on the shaft (2) and the fan hanger (10) in the center of the top surface of the fan fan, made of synthetic resin material, Two sheets of fan paper (8) coated with heat-sealable synthetic resin film or adhesive on one side are cut to a size smaller than the shape of the stretchable safety frame (4). As a function of the present invention constituted as described above, the fan rod 3 and the fan paper 8 are combined to be mounted on a heating pressurizer, and then heated at 140 ° C. or higher and 800 ^NG / ^CM2 pressure for 3 seconds to 4 seconds. Hot pressing for seconds to coat fan paper (8) During the period of fusion of the heat-sealing synthetic resin film, the fan rods (3), the elastic safety frame (4), the elastic frame (5), and the buried frame (6) do not reach the melting temperature of around 170 ° C, respectively. After expansion by 1% to 2% in the direction formed according to the length, the unit volume and the shape of the resin (the actual occurrence between the general operations of the other types of synthetic resin fan blades that have been executed so far), it is taken out from the gluer and cooled in the air. In the process, all the scaffolds (3) have a large volume of bending strength (2) is connected to the lower end of the bending strength is high, so the downward shrinkage to the vertical line (縱 線) while the lower elastic strength elastic safety frame ( 4) cut off, and the elastic safety frame (4) in the shape of a toy pattern formed by the unit of the independent shape is a refractive groove (1m / m in width, 1.5 m / m in length from the outer end) (7) refraction And does not deform the face plate of the fan because it synchronizes with the shrinkage of the fan rods 3 without affecting the fan paper 8, and the buried frame 6 is buried between the bonded fan paper 8 Although the phenomenon of shrinkage expansion is not 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 frame 4 does not disturb the shape of the original ball pattern or the flat surface of the fan, and the screen printing unit 90 on the top of the shaft 2 quickly and inexpensively prints the randomness of the demand of the consumer on the fan. You want to print Debt hook end of the old Central (10) would wish to call correctly documented in the upholstery debt.

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 toy-shaped elastic safety frame of the shape separated by unit makes the flat surface of the fan flexible. It has a lot of airflow, feels smooth to the touch, inevitably shrinks and expands according to the high and low ambient temperature, and uses the characteristic of the elastic seat frame, which changes the angle of refraction. The fine and diverse patterns are created to make you feel new all the time, and there is a fan hanger at the top to decorate the calligraphy of the fan correctly. There is an effect that screen printing can be done quickly and inexpensively.
