The conventional stiffener as described above is not good because the installation bracket is installed at the window, and in particular, the installation method is difficult and takes a lot of time to install because the box must be opened to install the conventional stiffener on the installation bracket. there was.

The one-touch dynamism (ED) according to an embodiment of the present invention is to overcome the problems of the conventional dynamism, and hereinafter, the one-touch dynamism (ED) according to an embodiment of the present invention is described as'the device' for convenience of explanation. It will be called as.

Referring to FIGS. 1 to 4, the device (one-touch stiffener ED) includes a housing 1, a handle 2, a link member 3, and a mounting arm 4.

First, the housing (1) is installed on the wall (W), the main body 11 including an inlet 111 opened on one side, a cover 12 for opening and closing the inlet 111, and the main body 11 It includes a receiving portion 13 formed by the cover 12.

1 to 4, the upper side of the main body 11 (meaning the upper side with respect to the vertical direction, which refers to the planar side with reference to Fig. 3) is open, a link to be described later accommodated in the receiving portion 13 The upper side of the main body 11 is opened for convenience in order to show the member 3, the mounting arm 4, and the like. In the present apparatus, the main body 11 is preferably closed on all sides except for the inlet 111 so as to form an accommodation space S inside.

1 to 4, the handle 2 is disposed outside the housing 1. More specifically, the body 11 may include a first side surface 112 including a through hole 112a through which the handle 2 passes. The handle 2 may pass through the inside (receiving space S or the receiving part 13) and outside of the housing 1 through the through hole 112a. That is, a part of the handle 2 is disposed outside the housing 1.

Here, the through-hole 112a has a length (length in the left and right direction based on FIG. 3) than the width of the handle 2 (exemplarily, the length in the horizontal direction based on FIG. 3) so that the handle 2 can be moved. It is preferably formed to be large.

5 is a view for explaining a link member.

1 to 5, the link member 3 is installed in the housing 1 and connected to the handle 2 to move the cover 12 to open and close the inlet 111 according to the movement of the handle 2 Let it.

In addition, the mounting arm 4 is connected to the governor 41 and installed in the receiving portion 13, and is connected to the handle 2 and protrudes to the outside of the receiving portion 13 as the handle 2 moves.

More specifically, the link member 3 is connected to the first link 311, the first link 311 and the handle 2 installed inside the main body 11 so as to be parallel to the wall W, and the handle ( 2) It may include a power transmission unit 31 including a second link 312 whose relative position with respect to the first link 311 changes as it moves. In addition, the power transmission unit 31 is rotatable through a joint and the other end of each of the first link 312 and the second link 312 so that the first link 311 and the second link 312 are interconnected. It may include a sixth link 313 to be connected.

At this time, the link member 3 is rotatably intersected with the second link 312, and is rotatably coupled to one end of the first link 311 to rotate as the second link 312 moves. It may include a power conversion unit 32 including 321.

Here, the other end means an end in a direction opposite to the direction from the main body 11 toward the inlet 111, and one end may mean an end in a direction from the main body 11 toward the inlet 111 side. In addition, the fact that each link is rotatably coupled may mean that it is rotatably coupled through a joint, and the same will be applied in the following description.

Exemplarily, the first link 311 is fixed and installed on the inner surface of the side (lower side based on FIG. 3) in contact with the wall W of the main body 11, and the above-described first side 112 is the main body ( In 11), it may be a surface facing the surface on which the first link 311 is installed. As described above, it is said that the handle 2 penetrates the inside and outside of the housing 1 through the through hole 112a of the first side 112, but the second link 312 includes the first link 311 and the handle 2 ) Is disposed between the inner ends of the second link 312 may be fixed to the inner end of the handle (2).

Here, the inner side refers to the direction toward the receiving space (S) or the receiving portion 13 based on the housing (1), and the outer side refers to the outer side of the housing (1), and the same will be applied in the following description. .

At this time, one end of the first link 311 and the second link 312 are rotatably connected (coupled) via a third link 321 and a joint, and as described above, the first link 311 and the second link ( 312) Each other end may be rotatably coupled to the sixth link 313.

Referring to FIG. 3 for example, when the handle 2 moves in a horizontal direction from right to left (a direction parallel to the first link 311), the power is applied to the second link 312 It is transmitted from right to left with respect to the first link 311 by the sixth link 313 and the third link 321 rotatably coupled with each of the second link 312 and the first link 311. have. That is, the second link 312 may perform translational movement with respect to the first link 311 by the sixth link 313 and the third link 321 as the handle 2 moves.

At this time, as the second link 312 moves to the left with respect to the first link 311, the third link 321 has a rotation shaft (link member 3) having one end (left end) of the first link 311 ), the rotation axis of each link is rotated to the left in the height direction of the wall W (which may have a longitudinal direction parallel to the plane-bottom direction based on FIGS. 3 and 5), and the third link ( 321 may serve as a lever for rotating the fourth link 331 serving as a crank in a section 4 link (crank-rocker mechanism) to be described later.

1 to 5, the link member 3 is rotatably coupled at one end (left end toward the inlet 111) of the second link 312, and is coupled to the cover 12 As the fourth link 331 connected to the arm 4 and the third link 321 rotate, both ends of the third link 321 and the third link ( It may include a power output unit 33 including a fifth link 332 coupled to 321 and each rotatably.

Based on the intersection of the third link 321 and the second link 312, the length from the intersection of the third link 321 to the end of the fifth link 332 is the length of the fourth link 331 It is preferably formed to be larger. In addition, it is preferable that the length from the intersection point to the end of the second link 312 coupled to the fourth link 331 is shorter than the length of the fifth link 332.

That is, as described above, the third link 321, which acts as a lever in the section 4 link (crank-rocker mechanism), rotates according to the translational movement of the second link 312 (moving to the left based on FIG. 3). , The fifth link 332 connected to the third link 321 may rotate the fourth link 331 using one end of the second link 312 as a rotation axis. That is, the fourth link 331 may serve as a crank rotating by the third link 321 serving as a lever in the fourth link (crank-rocker mechanism).

At this time, the cover 12 is coupled to the fourth link 331 of the power output unit 33, and as the fourth link 331 rotates using one end of the second link 312 as a rotation axis, the second link ( The inlet 111 of the main body 11 can be opened by rotating with one end (left end) of 312 as a rotation shaft.

In addition, as described above, it was said that the mounting arm 4 is coupled to the cover 12 and connected to the fourth link 331. For example, the mounting arm 4 is the fourth link 331 to the second link 312 It is coupled to the fourth link 331 so as to extend in a direction opposite to the direction toward one end (left end), and one side is coupled to the cover 12, so that the fourth link 331 is one end of the second link 312 As the (left end) is rotated with the rotational shaft, one end (left end) of the second link 312 may be rotated with the rotational axis.

On the other hand, the end of the third link 321 coupled to the first link 311 and the portion to the intersection are parallel to the sixth link 313 and coupled to the sixth link 313 of the second link 312 The end of the first link 311, the sixth link 313, and the first link 311 of the third link 321 so that the end and the portion up to the intersection point are parallel to the first link 311 And it may be preferable that the portion up to the intersection point and the end portion coupled to the sixth link 313 of the second link 312 and the portion up to the intersection point form a parallelogram.

In this way, as the handle 2 moves, the handle 2 and the fixed second link 312 are rotatably coupled to the first link 311 with a fixed position. The first link 311 is translated by the link 313, and at this time, the position of one end (left end) of the first link 311 coupled with the third link 321 is fixed, whereas the second link The third link 321 is rotated using one end of the first link 311 as a rotation axis as the crossing point is moved by translational movement of 312 to serve as a lever of a four-section link (crank-rocker mechanism), and , As the third link 321 rotates like a lever of a crank-rocker mechanism, the fifth link 332 rotates the fourth link 331 to one end (left end) of the second link 312 as a rotation axis. By rotating it, the cover 12 connected to the fourth link 331 is rotated to open the inlet 111 of the body 11 and the mounting arm 4 protrudes from the receiving portion 13.

That is, since the present apparatus includes the link member 3 described above, there is an advantage that the inlet 111 of the main body 11 can be opened and closed by rotating the cover 12 only by a simple translational movement of the handle 2.

In addition, since the mounting arm 4 is also coupled to the cover 12 side and protrudes from the receiving portion 13 as the cover 12 is opened, the device is operated with only one touch of the handle 2 (translational movement). Since the device can be used intuitively, it is easy to install, so there is no need to receive training on a separate installation method, and the installation time is shortened, so that the device can be used quickly.

In particular, when not in use, the mounting arm 4 is accommodated in the receiving portion 13 and the cover 12 closes the inlet 111 of the main body 11, so that the governor 41 is attached to the mounting bracket in the conventional stiffener. There is an advantage in that the aesthetics are improved compared to the installed condition and the installation bracket installed at the window.

FIG. 6 is a view for explaining when the length of the link member of the one-touch stiffener installed on the wall is varied, and FIG. 7 is a view for explaining a link member including a second bent portion and a third bent portion, and FIG. 8 Is a view for explaining the position change of the fourth link according to the movement of the handle in the link member including the second bent portion and the third bent portion, and FIG. 9 is a view in which each of the second bent portion and the third bent portion is bent. It is a diagram for explaining the position change of the second link according to the degree.

1 to 9, the user who uses the device does not move the handle 2 a relatively large distance (length in the left and right direction based on FIG. 3), and the mounting arm 4 is moved from the receiving portion 13 It can be said that the user's convenience increases when protruding. Preferably, the user should be able to use the device even if the user moves the handle 2 by less than 30 cm.

However, when each of the second link 312 and the third link 321 is in a straight line as shown in FIGS. 5 and 6 [A], the fourth link on which the governor 41 is installed even when the handle 2 is moved ( Since 331 is not perpendicular to the length direction of the wall W (the length in the left-right direction based on FIG. 6), it is difficult to use the device.

To compensate for this, if the handle 2 is moved more, the user's convenience is reduced, and in order to move the handle 2 more, the length of the through hole 112a to be described later (the length in the wah direction based on FIG. 6) is also increased. If necessary, the size of the housing 1 may be increased.

At this time, if the length of each of the second link 312 and the third link 321 is increased as shown in [B] of FIG. 6, the length of each of the second link 312 and the third link 321 may not be increased. Compared to the case (see [A] of Fig. 6), the wall (W) and the fourth link 331 are closer to the vertical, but the fourth link 331 and the wall (W) are still not vertical and the fourth link 331 does not sufficiently protrude through a window provided on one side of the wall W (left side with reference to FIG. 6 ).

In order to compensate for this, if the handle 2 is moved further as shown in Fig. 6 [A], the user convenience is similarly reduced. In particular, since the length of each of the second link 312 and the third link 321 is increased, the housing The size of (1) must be increased, and in that case, there is a problem that installation on the wall (W) becomes difficult.

At this time, referring to FIGS. 7 to 9, in the present apparatus, the second link 312 includes a second protrusion 2P connected to the second link 312 based on the intersection point with the third link 321 and It includes a second non-protruding portion (2PN) connected to the sixth link 313, and the third link 321 is a third protruding portion (3P) connected to the fifth link 332 based on the intersection point. ) And a third non-protruding portion (3PN) connected to the first link 311, wherein the second protruding portion (2P) is bent by a predetermined angle so as to be close to the third non-protruding portion (3PN). A second bent part 312a may be included, and the third protruding part 3P may include a third bent part 321a bent by a predetermined angle so as to be close to the second protruding part 2P.

Exemplarily, at least one of the second bent part 312a and the third bent part 321a may be bent at an intersection so that the second bent part 312a may be the second protruding part 2P, and the third bent part ( 321a) may be the third protruding portion 3P.

Preferably, the predetermined angle may be 100ㅀ to 120ㅀ, more preferably 110ㅀ.

If the predetermined angle is less than 100°, the wall (W) and the fourth link 331 are not vertical, and the fourth link 331 is difficult to sufficiently protrude through the window, and when the predetermined angle exceeds 120°, FIG. 9 As shown in [B] of, interference may occur between the fourth link 331 and the wall W.

It is preferable that the predetermined angle is 150ㅀ to 170ㅀ, and it may be more preferable that the predetermined angle is 160ㅀ.

When the predetermined angle is less than 150°, the wall (W) and the fourth link 331 are not vertical, and the fourth link 331 is difficult to sufficiently protrude through the window, and the predetermined angle exceeds 170°. As shown in [B] of 9, interference may occur between the fourth link 331 and the wall W.

As such, the device includes the second bent part 312a and the third bent part 321a, so that the fourth link 331 can be made perpendicular to the wall W with relatively little movement of the handle 2. It has the advantage of being able to protrude through the window.

In particular, since the predetermined angle is 100ㅀ to 120ㅀ, and the predetermined angle is 150ㅀ to 170ㅀ, the fourth link 331 can be made to be perpendicular to the wall (W) even if the handle (2) is moved only about 10cm. It is possible to protrude through (the fourth link 331 is rotated about 180°), and there is an advantage that the separation distance between the wall W and the fourth link 331 can be formed by 40cm or more.

At this time, when the handle 2 is moved by about 10.7cm or more, the fourth link 331 is rotated further, causing inconvenience in use, so that the length of the through hole 112a is increased so that the handle 2 does not move more than 10.7cm. It is preferably formed.

Illustratively, the length of the sixth link 313 may be 90mm to 110mm, the length of the first link 311 may be 190mm to 210mm, the length of the fifth link 332 may be 212mm to 232mm, and , The length of the fourth link 331 may be 117 mm to 137 mm, the length from one end (rotation shaft) of the second link 312 to the intersection point may be 194 mm to 214 mm, and in the third link 321 The length from the end (rotation shaft) coupled to the fifth link 332 to the intersection may be 225 mm to 245 mm.

The length of the sixth link 313 is 100mm, the length of the first link 311 is 200mm, the length of the fifth link 332 is 222mm, the length of the fourth link 331 is 127mm, the second link 312 It is more preferable that the length from one end (rotation shaft) of the crossing point to the intersection point may be 204 mm, and the length from the end (rotation shaft) coupled to the third link 321 to the fifth link 332 to the intersection point is 235 mm. can do.

The link member 3 described above is described as being rotated about 180° by the cover 12 and the mounting arm 4 by the coupling structure of each link, but the cover 12 and the mount by different coupling structures of each link It goes without saying that the angle of rotation of the arm 4 can be changed differently.

10 is a view for explaining a clasp of a handle.

1, 2, 4, and 10, the device is rotatably coupled to the inner surface of the cover 12, the reel 42 for winding or unwinding the rope 43 wound around the governor 41 It may include.

Here, the inner side means a direction toward the receiving portion 13 of the housing 1 as described above.

For example, the reel 42 may be coupled to the inner surface of the cover 12 so as to rotate around the normal direction of the inner surface of the cover 12 as a central axis. Similarly, the governor 41 may also be coupled to the mounting arm 4 so as to rotate in an axis parallel to the rotation axis of the reel 42. The coupling method of the cover 12 and the reel 42 and the coupling (connection) method of the mounting arm 4 and the governor 41 may be a method commonly used in the relevant field.

The rope 43 wound around the governor 41 is in a state in which one of both sides is connected to the belt 44 and the other is wound around the reel 42 based on the governor 41. When the user who uses the device wears the belt 44 on the body while the holding arm 4 protrudes from the receiving part 13 by operating the handle 2 and the belt 44 moves downward The governor 41 acting as a pulley controls the moving speed of the rope 43 moving on the governor 41, and at the same time, the other side of the rope 43 wound around the reel 42 is released.

The governor 41 is commonly used in the relevant field, and a more detailed description thereof will be omitted.

As described above, the device includes the reel 42 coupled to the cover 12 so as to be rotatable, so it is not necessary to throw the reel 42 out of the window like a conventional stiffener, and thus, the reel 42 is thrown out of the window. There is an advantage in that it is possible to prevent a collision accident and the like.

In addition, as described above, it was said that the main body 11 may include a first side surface 112 including a through hole 112a through which the handle 2 passes, and the first side surface 112 is formed in the through hole 112a. It may include an insertion hole (112b) spaced apart along the horizontal direction. Here, the horizontal direction may mean a moving direction of the handle 2.

At this time, the handle 2 is an extension 21 extending along the horizontal direction (the moving direction of the handle 2) (the extension 21 may be disposed on the upper or lower side of the handle 2, and the vertical bar is And the handle 2 moves in the horizontal direction and the inlet 111 is opened and inserted into the insertion hole 112b from the end of the extension 21 to the first side surface 112 It may include a clasp 22 that is bent into.

For example, the clasp 22 may be inserted into the insertion hole 112b while the fourth link 331 is perpendicular to the wall W or is close to the vertical.

Through this, there is an advantage in that an accident caused by the rotation of the mounting arm 4 while the user is moving down by wearing the belt 44 can be prevented.

In addition, since the insertion hole 112b is formed on the first side 112 where the through hole 112a through which the handle 2 passes is formed, the user can more intuitively insert the clasp 22 into the insertion hole 112b. There is an advantage that it can be.

11 is a view for explaining a load applied to a handle, a link member, and a mounting arm.

1 to 11, the mounting arm 4 is preferably formed of a metallic material in order to impart sufficient rigidity, since a large load is applied when the user wears the belt 44 to descend. In addition, since the load transmitted to the mounting arm 4 is also connected to the link member 3 and the handle 2 connected to the mounting arm 4, at least one of the link member 3 and the handle 2 is formed of a metal material. It is desirable to be.

At least one of the mounting arm (4), the handle (2) and the link member (3) is preferably formed of SS275, which is a rolled steel material for general structures, because not only rigidity but also corrosion resistance and excellent workability are required.

In addition, at least one of the mounting arm (4), the handle (2) and the link member (3) generates a large load when descending by the user wearing the belt 44, so it has a large cross-sectional second moment value compared to the mass, and the link shape It is preferable to be formed of a hollow square beam suitable for use as well. That is, at least one of the mounting arm 4, the handle 2, and the link member 3 is formed by processing a hollow square beam made of SS275 material.

In addition, through the program, the maximum stress according to the second-order moment of the cross-section was analyzed as the thickness of the hollow square beam changed for a certain height and width. As a result of the analysis, the height and width were 5 cm, width 3 cm, and thickness 7 mm, which did not exceed the yield strength of the material. It is desirable to have a cross-sectional second moment of 25.0292 cm⁴.

FIG. 11 shows the occurrence of the mounting arm 4, the handle 2, and the link member 3 when a load of 5,000 N is applied to the portion where the governor 41 is connected from the mounting arm 4 through the ABAQUS 6.14 program. It is a figure which shows what analyzed the stress.

This stress analysis fixed the positions of the ends of each of the third link 321 and the sixth link 313, which are coupled to the first link 311, and 5,000 N may occur when the user descends by wearing the belt 44. The load was performed based on the load specified in the Fire Service Act.

As a result of the analysis, a maximum stress of 243.11 MPa occurred in area A of FIG. 11 and a maximum deflection of -5.9004 mm occurred.

Each link (the first link 311 to the sixth link 313) may be connected by a pin joint to interact, but may be connected using spipper bolts.

Stripper bolts are made using SCM435 (stainless steel bolts) and have a tensile strength of 1000N/mmㅂ, and since it is less than the stress generated in the hole where the pin is inserted, it can be tightened by referring to the specification table.

The diameters of the pins are all the same as 16mm, and the heights of the pins are different depending on the fastening parts. Specifically, when three links are fastened, the pins connecting the fourth link 331 may have a height of 150mm and 70mm.

On the other hand, the housing 1 is accommodated in the inner (receiving portion 13) as described above, the link member 3, the mounting arm 4, the reel 42, and the like. It does not hit and may be formed of a metal material having rigidity to protect the link member 3, the mounting arm 4, the reel 42, and the like accommodated inside.

At this time, the process of installing the link member (3), the mounting arm (4), the reel (42), etc. to the housing (1), work at the place where the housing (1) is installed (for example, cleaning the place where the housing (1) is installed) , Paper, tile, moving, etc.), scratches may occur on the outer surface of the housing 1.

In addition, the housing 1 is installed on the wall W on which the window is formed, and as the housing 1 is cleaned, there is a concern that corrosion may occur due to contact with water and the like.

In particular, if scratches are generated on the outer surface of the housing 1 for the above reasons, the corrosion rate may be accelerated by promoting crevice corrosion, and when corrosion occurs on the outer surface of the housing 1, stress is concentrated and stress corrosion cracking occurs. Because of this, problems such as accelerating cracking may occur.

Referring to FIG. 12, the housing 1 may include a coating film G provided on an outer surface as a means for solving the above problem. The coating film (G) is in contact with the outer surface of the housing (1), but is in contact with the adhesive layer (G1) that is softened in the first temperature range, the heating layer (G2) provided on the adhesive layer (G1), and the heating layer (G2). The intermediate layer (G3) that is provided but is softened in a second temperature range higher than the first temperature range, and a protective layer (G4) provided on the intermediate layer (G3) and softened at a third temperature higher than the second temperature range. It may include.

This coating film (G) includes a protective layer (G4), so that the surface is high in hardness and abrasion resistance is excellent, so that scratches and the like in the housing 1 are suppressed, and it has water repellency to prevent corrosion of the housing 1. Can be suppressed. In particular, the coating film (G) includes an adhesive layer (G1) and an intermediate layer (G3) that are softened at a lower temperature in the first temperature range and the second temperature range, respectively, unlike the protective layer G4 on the surface, so that the surface of the coating film (G) While maintaining the physical and chemical properties of the protective layer (G4) provided on the surface, it is possible to more effectively remove the residual stress of the coating film (G) due to external environments such as thermal expansion and bending, thereby suppressing damage such as peeling, thereby reducing the service life. Because it can be extended, the housing 1 can be protected from the external environment for a longer time.

In a specific embodiment, the adhesive layer G1 may include polybutylacrylate (PBA) and polymethyl methacrylate (PMMA). When the thickness of the adhesive layer (G1) is thick, a temperature gradient between the heating layer (G2) and the portion that contacts the outer surface of the housing (1), which will be described later, causes softening of the portion from the adhesive layer (G1) to the outer surface of the housing (1). Since it may not be made smoothly, it is preferable that the thickness is 0.020mm to 0.150mm.

Exemplarily, the adhesive layer G1 may be formed by heat-coating polybutyl acrylate and polymethyl methacrylate. The softening temperature of the adhesive layer G1 is 90°C to 100°C, corresponding to the first temperature range.

In this way, since the adhesive layer G1 in the coating film G is softened in the first temperature range, which is the lowest temperature, peeling is suppressed because of excellent adhesion to the outer surface of XXX.

The heating layer G2 is provided on the adhesive layer G1 and includes polyacetylene and iodine. Polyacetylene does not have a gap through which electrons flow in the conjugated double bond state, but since the gap can be widened by incorporating heterogeneous low molecules such as iodine, electrons flow, and when electricity is applied, heat is generated by electrical resistance.

In this way, by including the heating layer (G2), since there is no need to apply a large voltage to soften the adhesive layer (G1) and the intermediate layer (G3) to be described later, the service life of the coating film (G) is more economically extended. There is an advantage that you can do it.

The intermediate layer G3 may include 100 parts by weight of the cellulose acetate butyrate and 200 parts by weight of the carboxylate acrylic copolymer. If the weight ratio is out of the above, the adhesive strength between the adhesive layer G1 and the protective layer G4 may be insufficient, and thus, there may be a problem that the film peels off during use. The softening temperature of the intermediate layer G3 is 150° C. to 160° C., corresponding to the second temperature range.

The protective layer (G4) may include 50 parts by weight of polymethylphenylsiloxane in toluene, 50 parts by weight of silicon-containing fibers, 50 parts by weight of silicon carbide, 6 parts by weight of manganese oxide, and 18 parts by weight of an organosilicon-titanium compound. have.

When the amount of polymethylphenylsiloxane is less than 50 parts by weight, the softening temperature decreases, the difference from the second temperature range decreases, the hardness decreases, and when it exceeds 50 parts by weight, it is not economical. When the content of the silicone-containing fiber is less than 50 parts by weight, the water repellency is deteriorated, and when it exceeds 50 parts by weight, the water repellency is not significantly improved, so it is not economical. If the amount of silicon carbide is less than 50 parts by weight, the abrasion resistance is reduced, and if it exceeds 50 parts by weight, the abrasion resistance is not significantly improved, so it is not economical. If the organosilicon-titanium compound is less than 18 parts by weight, surface hardness and abrasion resistance are reduced, and if it exceeds 18 parts by weight, the degree of hardening is not clear, which is not economical.

As such, the softening temperature of the protective layer G4 is 650° C. (the third temperature), which maintains hardness even at a temperature lower than the third temperature, which is higher than the second temperature range, to maintain wear resistance and water repellency. The housing 1 can be effectively protected from the external environment.

As described above, the coating film G is provided on the outer surface of the housing 1, and residual stress such as compressive stress and tensile stress is generated due to the difference in the coefficient of thermal expansion from the housing 1, the shape and the bending due to external force. When such residual stress is generated, microincontinence, cracks, hillocks, wrinkles, fractures, etc., called crazing may occur in the coating film G.

Therefore, by applying electricity to the heating layer G2 so that the adhesive layer G1 and the intermediate layer G3 reach the first temperature range and the second temperature range, respectively, residual stress is removed in each of the adhesive layer G1 and the intermediate layer G3. Therefore, it is to suppress the occurrence of fracture or the like due to residual stress.

At this time, it is important that the heating layer G2 generates heat below the third temperature so that the protective layer G4 does not soften, so the adhesive layer G1 and the intermediate layer G3 reach the first temperature range and the second temperature range, respectively. Thus, even during the softening process, the protective layer G4 is not softened, and thus properties such as excellent hardness, abrasion resistance, and water repellency can be maintained.

In particular, when the heating layer G2 generates heat at a temperature adjacent to the first temperature range (e.g., 150°C) in the second temperature range, the softening degree of the intermediate layer G3 is less than that of the adhesive layer G1, and the intermediate layer G3 Since it serves as a buffer between the adhesive layer G1 and the protective layer G4, it can serve as a bridge between the adhesive layer G1 and the protective layer G4.

In other words, since the residual stress of the coating film G can be effectively dispersed and relaxed while maintaining the physical and chemical properties of the protective layer G4, the housing 1 can be continuously protected from external environments such as scratches and corrosion. There is an advantage.
