Mode for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing an example of a vehicle window glass with a holder according to an embodiment. As shown in FIG. 1, the vehicle window glass 1 with a holder according to the present embodiment includes a vehicle window glass 101 and holders (vehicle window glass holders) 100_1 and 100_2 that hold the vehicle window glass 101. In FIG. 1, a configuration example in which two holders 100_1 and 100_2 are attached to the vehicle window glass 101 is shown. However, the number of holders 100 attached to the vehicle window glass 101 may be one or more, and can be arbitrarily determined by the user. In this specification, the holders 100_1 and 100_2 may also be collectively referred to as the holder 100.

[0013] In the present embodiment, the vehicle window glass 101 may be a single-pane glass or a laminated glass. In the case of laminated glass, for example, it can be configured by sandwiching an interlayer film between two glass plates. For the interlayer film, for example, polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), or the like can be used.

[0014] In this embodiment, a vehicle window glass 101 is held by holders 100_1 and 100_2, and these holders 100_1 and 100_2 are fixed to a lifting device (not shown). The vehicle window glass 101 moves in the vertical direction by the driving force of the lifting device (not shown).

[0015] Next, the holder according to the present embodiment will be described. Fig. 2 is an exploded perspective view showing an example of the holder according to the present embodiment. Fig. 3 is a perspective view showing an example of the holder according to the present embodiment. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is a plan view showing an example of the holder according to the present embodiment.

[0016] As shown in FIG. 2, the holder 100 according to the present embodiment includes a main body 10 and a buffer section 20. The main body 10 includes a bottom 11, a first side wall 12 extending from one side (negative side in the y-axis direction) of the bottom 11 toward the upper side (positive side in the z-axis direction), and a second side wall 13 extending from the other side (positive side in the y-axis direction) of the bottom 11 toward the upper side (positive side in the z-axis direction). That is, the main body 10 has a groove 14 having a substantially U-shaped cross section as viewed from the x-axis direction. Typically, the main body 10 is made of a metal material. By making the main body 10 of a metal material, the rigidity of the holder 100 can be increased. The main body 10 may be made by assembling a plurality of parts (for example, the bottom 11, the first side wall 12, and the second side wall 13). The main body 10 may also be integrally formed by casting or the like. The metal material constituting the main body 10 may be, for example, stainless steel, aluminum, iron, or the like. The bottom 11 extends to the negative z-axis direction, and the plate-like portion of the bottom 11 on the negative z-axis direction side is fixed to a lifting device (not shown). Note that the approximate U-shape in this specification may have an arc-shaped or linear bottom, and may have a corner at the boundary between the bottom and the side wall.

[0017] The buffer section 20 includes a first buffer member 21 provided at one end side (positive side in the x-axis direction) in the direction in which the groove 14 of the main body section 10 extends, and a second buffer member 22 provided at the other end side (negative side in the x-axis direction). The first buffer member 21 and the second buffer member 22 abut against the first and second side wall sections 12 and 13 of the main body section 10, respectively, and have a substantially U-shaped cross section as viewed from the x-axis direction. Specifically, the first buffer member 21 and the second buffer member 22 each include a bottom section extending in the y-axis direction, and two side wall sections extending from both sides of the bottom section in the y-axis direction to the positive side in the z-axis direction.

[0018] The buffer section 20 further includes a first connecting member 23 that connects the first buffer member 21 and the second buffer member 22 on the first side wall section 12 side, and a second connecting member 24 that connects the first buffer member 21 and the second buffer member 22 on the second side wall section 13. The gap section 25 is provided in a region sandwiched between the first buffer member 21 and the second buffer member 22. The gap section 25 is a region that can be filled with an adhesive member 80 that bonds the vehicle window glass 101 to the first and second side wall sections 12, 13.

[0019] The buffer section 20 is made of a resin material. Examples of the resin material that can be used include thermoplastic elastomer resins such as ethylene propylene diene rubber (EPDM), silicone rubber, olefin-based thermoplastic elastomer (TPO), ABS resin, polyethylene (PE) resin, and polypropylene (PP) resin. The buffer section 20 can be integrally formed by injection molding using these materials.

[0020] 3, the buffer part 20 is attached to the groove 14 of the main body part 10 (i.e., inside the first and second side wall parts 12, 13). The first and second buffer members 21, 22 are provided so as to abut against the first and second side wall parts 12, 13 of the main body part 10, respectively. When the vehicle window glass 101 is placed in the holder 100, the first and second side wall parts 12, 13 of the main body part 10 hold the vehicle window glass 101 via the first and second buffer members 21, 22.

[0021] 4 and 5, a part of the buffer section 20 is provided with gaps 25_1 and 25_2 that can be filled with an adhesive member 80 that bonds the vehicle window glass 101 to the first and second side wall sections 12 and 13. That is, the gap 25_1 on the first side wall section 12 side is formed in an area surrounded by the first side wall section 12, the first buffer member 21, the second buffer member 22, the first connecting member 23, and the vehicle window glass 101. Similarly, the gap 25_2 on the second side wall section 13 side is formed in an area surrounded by the second side wall section 13, the first buffer member 21, the second buffer member 22, the second connecting member 24, and the vehicle window glass 101.

[0022] The adhesive member 80 is filled in the gap 25_1 on the first side wall portion 12 side and the gap 25_2 on the second side wall portion 13 side. As a result, the first side wall portion 12 and the vehicle window glass 101 are bonded via the adhesive member 80. Also, the second side wall portion 13 and the vehicle window glass 101 are bonded via the adhesive member 80. Furthermore, in this embodiment, as shown in FIG. 4, the adhesive member 80 can be filled on the bottom surface of the vehicle window glass 101. As a result, the bottom 11 of the main body portion 10 and the bottom surface of the vehicle window glass 101 are bonded via the adhesive member 80. Also, as shown in FIG. 5, when the adhesive member 80 is filled so as to contact the first and second buffer members 21 and 22, the buffer portion 20 is fixed to the vehicle window glass 101. For example, an epoxy-based or urethane-based adhesive is used as the adhesive member 80. In addition, Figures 4 and 5 show a configuration example in which some voids 25 remain after filling with adhesive material 80, but in this embodiment, adhesive material 80 may be filled in such a way that no voids 25 remain.

[0023] As described above, in this embodiment, a part of the buffer section 20 is provided with the gap section 25 into which the adhesive member 80 for bonding the vehicle window glass 101 to the first and second side wall sections 12, 13 can be filled. Therefore, the adhesive member can be sufficiently filled between the vehicle window glass 101 and the holder 100, so that the vehicle window glass 101 and the holder 100 can be firmly fixed to each other.

[0024] FIG. 22 and FIG. 23 are an exploded perspective view and a side view showing a holder according to the related art, respectively. As shown in FIG. 22, a holder 200 according to the related art includes a main body portion 210 and a buffer portion 220. The main body portion 210 includes a bottom portion 211, a first side wall portion 212 extending upward (in the positive z-axis direction) from one side (the negative y-axis direction side) of the bottom portion 211, and a second side wall portion 213 extending upward (in the positive z-axis direction) from the other side (the positive y-axis direction side) of the bottom portion 211. That is, the main body portion 210 has a groove 214 having a substantially U-shaped cross-sectional shape when viewed from the x-axis direction.

[0025] The buffer portion 220 has a substantially U-shaped cross-sectional shape. As shown in FIG. 23, by disposing the buffer portion 220 in the groove 214 of the main body portion 210, the buffer portion 220 is attached to the main body portion 210. When a vehicle window glass 201 is disposed on the holder 200, the first and second side wall portions 212 and 213 of the main body portion 210 hold the vehicle window glass 201 via the buffer portion 220.

[0026] However, in the holder 200 according to the related art, the entire inner side surface of the buffer portion 220 is configured to be in contact with the vehicle window glass 201. For this reason, an adhesive member cannot be sufficiently filled between the vehicle window glass 201 and the holder 200, and there may be a case where the vehicle window glass 201 and the holder 200 cannot be firmly fixed.

[0027] On the other hand, in the present embodiment, as shown in FIGS. 4 and 5, a void portion 25 capable of filling an adhesive member 80 for adhering the vehicle window glass 101 to the first and second side wall portions 12 and 13 is provided in a part of the buffer portion 20. Therefore, since the adhesive member can be sufficiently filled between the vehicle window glass 101 and the holder 100, the vehicle window glass 101 and the holder 100 can be firmly fixed.

[0028] In addition, in this embodiment, the main body 10 is made of a metal material. This increases the rigidity of the holder 100. For example, if the entire holder is made of a resin material, it is not necessary to provide the buffer section 20 as in this embodiment, but the rigidity of the entire holder decreases. This causes a problem of a decrease in the force supporting the vehicle window glass. In contrast, in this embodiment, the main body 10 is made of a metal material, and the buffer section 20 made of a resin material is attached to the groove 14 of the main body 10. This increases the rigidity of the entire holder 100 while properly holding the vehicle window glass 101, thereby increasing the force supporting the vehicle window glass (glass support rigidity).

[0029] Next, another configuration example of the holder according to the present embodiment will be described.

[0030] FIG. 6 is a perspective view showing another example of the holder according to the present embodiment. The holder 100a shown in FIG. 6 includes a main body 10a and a buffer 20a. In the configuration example shown in FIG. 6, a fitting portion 15 is provided on the outer side surface of each of the first and second sidewalls 12 and 13 of the main body 10a. In addition, the first and second buffer members 21 and 22 each include a protrusion 26 that passes through the substantially U-shaped top surface of the main body 10a and fits into each of the fitting portions 15 of the first and second sidewalls 12 and 13. In this way, the protrusion 26 of the buffer 20a is configured to fit into each of the fitting portions 15 of the first and second sidewalls 12 and 13, so that the buffer 20a can be fixed to the main body 10a.

[0031] 6, the first buffer member 21 includes a first contact portion 27 that contacts the outer side surface (side surface on the positive x-axis direction) of the main body portion 10a at one end (x-axis direction positive side) in the direction in which the groove 14 of the main body portion 10a extends. Similarly, the second buffer member 22 includes a second contact portion (not shown in FIG. 6) that contacts the outer side surface (side surface on the negative x-axis direction) of the main body portion 10a at the other end (x-axis direction negative side) in the direction in which the groove 14 of the main body portion 10a extends. In this way, by providing the first and second contact portions 27 to the buffer portion 20a, it is possible to limit the displacement of the buffer portion 20a in the x-axis direction relative to the main body portion 10a.

[0032] Fig. 7 is a perspective view showing another example of the buffer part included in the holder according to the present embodiment. Fig. 8 is a side view showing another example of the holder according to the present embodiment. The holder 100b shown in Fig. 8 includes a main body part 10b and a buffer part 20b.

[0033] 7 and 8, the first and second cushioning members 21, 22 have protrusions 28 that protrude from the surfaces of the first and second cushioning members 21, 22 toward the first and second side wall portions 12, 13, respectively. Also, as shown in Fig. 8, the main body portion 10b has recesses 16 on the inner side surfaces of the first and second side wall portions 12, 13. In the configuration example shown in Figs. 7 and 8, the protrusions 28 of the first and second cushioning members 21, 22 fit into the recesses 16 of the first and second side wall portions 12, 13, thereby positioning the first and second cushioning members 21, 22 in the main body portion 10a.

[0034] 7 and 8, similarly to the configuration example shown in Fig. 6, the buffer part 20b includes the first and second contact parts 27. Therefore, it is possible to limit the displacement of the buffer part 20b in the x-axis direction relative to the main body part 10b.

[0035] 9 to 11 are an exploded perspective view, a perspective view, and a side view, respectively, showing another example of the holder according to the present embodiment. The holder 100c shown in FIGS. 9 to 11 includes a main body 10c and a buffer section 20c. In the configuration example shown in FIGS. 9 to 11, fitting sections 17 are provided on the outer side surfaces of the first and second sidewall sections 12, 13 of the main body 10c. The buffer section 20c includes a member 33 that covers the substantially U-shaped top surface of the main body 10c, and an outer member 34 that extends from the member 33 to the negative side in the z-axis direction. A protrusion 30 is provided at the end of the outer member 34 on the negative side in the z-axis direction.

[0036] Each of the protrusions 30 of the first and second buffer members 21, 22 is configured to fit into the fitting portion 17 of each of the first and second sidewall portions 12, 13. In this manner, the protrusions 30 of the buffer portion 20c are configured to fit into the fitting portions 17 of the first and second sidewall portions 12, 13, so that the buffer portion 20c can be fixed to the main body portion 10c. In addition, in the configuration example shown in Figs. 9 to 11, the outer member 34 of the buffer portion 20c is configured to cover the outer side surfaces of the first and second sidewall portions 12, 13 of the main body portion 10c. Therefore, the first and second sidewall portions 12, 13 of the main body portion 10c can be protected using the outer member 34 of the buffer portion 20c, so that the first and second sidewall portions 12, 13 can be prevented from being corroded or the like.

[0037] 9 to 11, similarly to the configuration example shown in Fig. 6, the buffer part 20c includes the first and second contact parts 27. This makes it possible to limit the displacement of the buffer part 20c in the x-axis direction relative to the main body part 10c.

[0038] Fig. 12 is a cross-sectional view showing another example of the holder according to the present embodiment. A holder 100d shown in Fig. 12 includes a main body portion 10d and a buffer portion 20d.

[0039] In the configuration example shown in FIG. 12, the first and second buffer members 21, 22 each have a hollow portion 31 therein. By providing the hollow portion 31 in the first and second buffer members 21, 22 in this way, when the holder 100d holds the vehicle window glass 101, the variation in the plate thickness of the vehicle window glass 101 can be absorbed. That is, by providing the hollow portion 31 in the first and second buffer members 21, 22, the displacement amount of the first and second buffer members 21, 22 in the y-axis direction can be increased. Therefore, even if the plate thickness of the held vehicle window glass 101 varies, the first and second buffer members 21, 22 are displaced in the y-axis direction, and this variation can be absorbed. In addition, since the displacement amount of the first and second buffer members 21, 22 in the y-axis direction can be increased, the stress acting on the vehicle window glass 101 can be further alleviated. Furthermore, the holder 100d can appropriately hold the vehicle window glass 101 by the elastic force generated by the displacement of the first and second cushioning members 21, 22 in the y-axis direction.

[0040] In the configuration example shown in FIG. 12, a curvature portion 29 having a predetermined curvature radius is provided at the end portion on the z-axis direction positive side of the first and second buffer members 21, 22 of the buffer portion 20d. When the curvature portion 29 is provided in this manner, interference between the holder 100d and the vehicle window glass 101 can be suppressed when the vehicle window glass 101 is attached to the holder 100d. Therefore, the vehicle window glass 101 can be smoothly attached to the holder 100d. The other configurations are the same as those shown in FIGS. 9 to 11. The curvature portion 29 may also be provided in the other configuration examples. The curvature portion 29 is formed, for example, by chamfering the end portion on the z-axis direction positive side of the first and second buffer members 21, 22 of the buffer portion 20d.

[0041] Fig. 13 is a cross-sectional view showing another example of the holder according to the present embodiment. Fig. 14 is a cross-sectional view showing a state in which a vehicle window glass is attached to the holder shown in Fig. 13. The holder 100e shown in Fig. 13 includes a main body portion 10e and a buffer portion 20e.

[0042] 13, the first and second side wall portions 12, 13 of the main body portion 10e each include a portion 18 where the inner walls of the first and second side wall portions 12, 13 are scraped away. When the first and second side wall portions 12, 13 each have a portion 18 where the inner walls of the first and second side wall portions 12, 13 are scraped away in this manner, gaps are formed between the first and second side wall portions 12, 13 and the first and second buffer members 21, 22, respectively, when the buffer portion 20e is attached to the main body portion 10e.

[0043] As shown in Fig. 14, when the vehicle window glass 101 is placed in the holder 100e, the first and second cushioning members 21, 22 are displaced toward the portion 18 where the inner wall has been cut. In other words, the first and second cushioning members 21, 22 expand in the y-axis direction, thereby absorbing variations in the plate thickness of the vehicle window glass 101. In addition, the amount of displacement of the first and second cushioning members 21, 22 in the y-axis direction can be increased, thereby further reducing the stress acting on the vehicle window glass 101. Other configurations are the same as those shown in Figs. 9 to 11.

[0044] Fig. 15 is a perspective view showing another example of the buffer part included in the holder according to the present embodiment. Fig. 16 is a perspective view showing a state in which the buffer part shown in Fig. 15 is attached to a vehicle window glass. Fig. 17 is a perspective view showing a state in which the holder according to the embodiment is attached to a vehicle window glass. Fig. 18 is a perspective view showing another example of the holder according to the embodiment.

[0045] In this embodiment, a member having a shape as shown in Fig. 15 may be used as the cushioning member 41. That is, the cushioning member 41 is a plate-like member 51 having a shape in which a central portion 54 can be bent. The cushioning member 41 is made of a resin material. An adhesive 52 is provided on one side of the central portion 54 of the plate-like member 51, and an adhesive 53 is provided on the other side. As the adhesives 52 and 53, for example, double-sided tape is used.

[0046] As shown in Fig. 16, when attaching the buffer member 41 to the vehicle window glass 101, the central portion 54 of the buffer member 41 is bent into a valley fold, and the buffer member 41 is attached to the vehicle window glass 101 using the adhesive materials 52 and 53. In the configuration example shown in Fig. 16, a state where two buffer members, that is, the first buffer member 41_1 and the second buffer member 41_2 are attached to the vehicle window glass 101 is shown.

[0047] Thereafter, as shown in Fig. 17, the main body portion 10f is attached to the vehicle window glass 101 to which the first and second buffer members 41_1 and 41_2 are attached. Then, by pouring an adhesive member (not shown) into the gap portion 25 formed between the first buffer member 41_1 and the second buffer member 41_2, the main body portion 10f can be fixed to the vehicle window glass 101. In the configuration example shown in Fig. 17, the first buffer member 41_1 and the second buffer member 41_2 constitute the buffer portion 20f. In the holder 100f shown in Fig. 17, the first and second side wall portions 12 and 13 of the main body portion 10f hold the vehicle window glass 101 via the first and second buffer members 41_1 and 41_2.

[0048] As shown in Fig. 18, the buffer portion 20f includes a first buffer member 41_1 provided on one end side (the plus side in the x-axis direction) in the direction in which the groove 14 of the main body portion 10f extends, and a second buffer member 41_2 provided on the other end side (the minus side in the x-axis direction). The first buffer member 41_1 and the second buffer member 41_2 each have a substantially U-shaped cross-sectional shape when viewed from the x-axis direction.

[0049] As shown in Figs. 17 and 18, a gap portion 25 is formed between the first buffer member 41_1 and the second buffer member 41_2. Specifically, the gap portion 25 on the first side wall portion 12 side is formed in a region surrounded by the first side wall portion 12, the first buffer member 41_1, the second buffer member 41_2, and the vehicle window glass 101. Similarly, the gap portion 25 on the second side wall portion 13 side is formed in a region surrounded by the second side wall portion 13, the first buffer member 41_1, the second buffer member 41_2, and the vehicle window glass 101.

[0050] An adhesive member (not shown) is filled into the gap 25 on the first side wall portion 12 side and the gap 25 on the second side wall portion 13 side. This causes the first side wall portion 12 and the vehicle window glass 101 to be bonded together via the adhesive member. Also, the second side wall portion 13 and the vehicle window glass 101 are bonded together via the adhesive member.

[0051] The configuration shown in Figs. 16 to 18 corresponds to a configuration in which the first connecting member 23 and the second connecting member 24 are omitted from the holder 100 shown in Figs.

[0052] 19 to 21 are cross-sectional views showing examples of the configuration of a vehicle window glass held by a holder according to the present embodiment. FIG. 19 to FIG. 21 show examples of the configuration of laminated glass. A vehicle window glass 101a shown in FIG. 19 includes two glass plates 110a, 111a and an intermediate film 112, and the two glass plates 110a, 111a are bonded to each other using the intermediate film 112. In the present embodiment, when the vehicle window glass 101a is placed in a vehicle, the glass plate 110a is the vehicle exterior glass plate, and the glass plate 111a is the vehicle interior glass plate. For example, polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) can be used for the intermediate film 112. The intermediate film 112 may have either a single layer structure or a multiple layer structure.

[0053] The two glass plates 110a, 111a are inorganic glass. Examples of inorganic glass include soda lime glass and aluminosilicate glass. The inorganic glass may be either unstrengthened glass or tempered glass. Unstrengthened glass is made by forming molten glass into a plate shape and slowly cooling it. Tempered glass is made by forming a compressive stress layer on the surface of unstrengthened glass. The tempered glass may be either physically strengthened glass (for example, air-cooled tempered glass) or chemically strengthened glass.

[0054] Although not shown, the two glass sheets 110a, 111a are formed to be convex toward the outside of the vehicle. Gravity forming, press forming, or the like is used for bending the glass sheets. In bending, the uniformly heated glass sheet may be rapidly cooled from a temperature near its softening point, and compressive stress may be generated on the glass surface due to the temperature difference between the glass surface and the inside of the glass, thereby physically strengthening the glass surface. After bending, the glass surface may be chemically strengthened by generating compressive stress on the glass surface by an ion exchange method or the like.

[0055] The thickness of the vehicle window glass 101a is preferably 2.8 mm to 10 mm, and more preferably 3.0 mm to 8.0 mm. When the thickness of the vehicle window glass 101a is 2.8 mm to 10 mm, it is possible to ensure sufficient transmittance as a vehicle window glass and sufficient rigidity. Here, if the vehicle window glass 101a having a thickness of 6.0 mm or less is used as glass for a frameless door, there is a risk that the window glass will bend when the door is opened or closed, for example. In contrast, the vehicle window glass with holder according to the present embodiment has a high glass supporting rigidity of the holder and can suppress bending of the window glass, so it is suitable for glass for a frameless door having a thickness of 6.0 mm or less.

[0056] The thickness of the glass plate 110a is preferably 1.1 mm to 3.6 mm, and more preferably 1.8 mm to 3.0 mm. When the thickness of the glass plate 110a is 1.1 mm to 3.6 mm, the weight of the vehicle window glass can be reduced and sufficient strength can be ensured. The thickness of the glass plate 111a is preferably 0.5 mm to 2.7 mm, and more preferably 0.5 mm to 2.3 mm. When the thickness of the glass plate 111a is 0.5 mm to 2.7 mm, the weight of the vehicle window glass can be reduced and the handleability of the glass plate 111a can be maintained good.

[0057] The thickness of the interlayer 112 is preferably 0.5 mm to 3.0 mm, and more preferably 0.5 mm to 2.8 mm. When the thickness of the interlayer 112 is 0.5 mm to 3.0 mm, it is possible to reduce the weight of the vehicle window glass and ensure sufficient impact resistance.

[0058] The vehicle window glass with holder, which includes the vehicle window glass 101a and a holder for holding the vehicle window glass 101a, is suitable for use as glass for frameless doors because the holder has high glass supporting rigidity, and therefore the window glass is less likely to bend when the door is opened or closed.

[0059] As shown in Fig. 20 and Fig. 21, in this embodiment, the vehicle window glass may have a shape in which the portion held by the holder bulges toward at least one of the first side wall portion 12 and the second side wall portion 13. That is, as in the vehicle window glass 101b shown in Fig. 20, the lower side of the glass plate 110b may be configured to bulge toward the negative side in the y-axis direction and the positive side in the y-axis direction. Also, as in the vehicle window glass 101c shown in Fig. 21, the lower side of one of the two glass plates 110c, 111c, bulges toward the negative side in the y-axis direction. Note that the lower side of the intermediate film 112 may be configured to bulge in the y-axis direction, similar to the lower sides of the glass plates 110b, 111b, and 110c.

[0060] By forming at least one of the two glass plates constituting the vehicle window glass in such a way that it bulges outward, the glass supporting rigidity when the vehicle window glass is held by the holder can be increased.

[0061] The present invention is not limited to the above embodiment, and can be modified as appropriate without departing from the spirit of the present invention. In the above embodiment, for example, the buffer unit 20 includes two buffer members (the first buffer member 21 and the second buffer member 22). However, in this embodiment, the number of buffer members included in the buffer unit 20 may be three or more.

[0062] 2 shows a configuration example in which the first connecting member 23 and the second connecting member 24 are provided at the upper ends of the first buffer member 21 and the second buffer member 22. However, in this embodiment, the first connecting member 23 and the second connecting member 24 may be provided at the lower ends or central parts of the first buffer member 21 and the second buffer member 22. Also, the number of each of the first connecting members 23 and the second connecting members 24 may be two or more.

[0063] Although the present invention has been described above in accordance with the above-described embodiment, the present invention is not limited to the configuration of the above-described embodiment, and naturally includes various modifications, alterations, or combinations that a person skilled in the art could make within the scope of the invention of the claims of the present application.
