Description

[Technical Field]

[0001] The present invention relates to a surface material mounting structure and a surface material mounting method for mounting a surface material using moldings that are attached to openings provided in a plate-like member from both sides of the plate-like member. [Background technology]

[0002] A surface material mounting structure has been known in the past in which a panel (surface material) is clamped and fixed between a pair of frame materials (moldings) and attached to an opening surrounded by the frame members of a frame door (see, for example, Patent Document 1). In this surface material mounting structure, the pair of frame materials that clamp the panel are bonded together with an adhesive at their opposing surfaces. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-55386 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described conventional surface material mounting structure, the opening surrounded by the frame member is wider than the pair of frame members surrounding the panel, so that the panel and pair of frame members can be easily fitted into the opening surrounded by the frame member. Therefore, the pair of frame members move slightly within the opening before being fixed. Because the pair of frame members to which the panel is attached are bonded with adhesive on their opposing surfaces, if the opposing frame members do not align more precisely, the opposing surface area of ​​the pair of frame members that move slightly within the opening will become smaller, resulting in a risk of a reduced adhesive surface area and insufficient adhesive strength. Therefore, the opposing frame members must be positioned more precisely to be bonded, resulting in poor manufacturability.

[0005] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a surface material mounting structure and a surface material mounting method that are easy to manufacture. [Means for solving the problem]

[0006] The main invention for achieving this object is a panel mounting structure in which a panel is mounted by surrounding the peripheral edge of the panel with a first molding attached to one side of the panel and a second molding attached to the other side of an opening provided in the panel, wherein the first molding has a protrusion, the second molding has a recess into which the protrusion is fitted, the panel is engaged with the protrusion and the recess, and one of the first and second moldings is attached by adhesive to the other of the first and second moldings or to the panel. Other features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a surface material mounting structure and a surface material mounting method that are excellent in manufacturability. [Brief explanation of the drawings]

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A surface material mounting structure according to one embodiment of the present invention will be described below with reference to the drawings. As an example of a surface material mounting structure according to this embodiment, a door 3 having a glass plate 2 as a surface material mounted in an opening 1a provided in a door body 1 as a plate-like member as shown in Fig. 1 will be taken as an example, and the surface material mounting structure and a surface material mounting method for mounting the glass plate 2 to the opening 1a (Fig. 3) will be described. Here, the plate-like member is a plate-like member having a substantially flat front and back surfaces, and includes door bodies such as shoji screens and doors, and interior wall materials such as plywood panels.

[0010] 1 and 2, in the surface material mounting structure of this embodiment, a rectangular glass plate 2 is mounted in a rectangular opening 1a provided in a door body 1 by a first molding 4 attached from one side of the door body 1 and a second molding 5 attached from the other side. In the following explanation, for convenience of explanation, the side to which the first molding 4 is attached will be referred to as the front side, and the side to which the second molding 5 is attached will be referred to as the back side, but the first molding 4 and the second molding 5 may be attached to either side of the door body 1. Also, while FIG. 2 shows a cross-sectional view of the portion of the door 3 where the glass plate 2 is attached to the door body 1, the vertical cross-section is similar.

[0011] The first molding 4 and the second molding 5 are formed by first molding members 40 or second molding members 50, each made of an extruded material, cut to an appropriate length and joined together into a rectangular frame. For example, both longitudinal ends of four first molding members 40 or four second molding members 50 are cut at a 45-degree angle, and the cut ends are butted together. A U-shaped pin (not shown) is inserted between the two butted first molding members 40 or second molding members 50 to join them. The mounting structure for the glass plate 2 in the door 3 is line-symmetrical on the left and right sides, so the following explanation will focus on the left side as an example and omit the right side.

[0012] First Embodiment 3, the first molding member 40 in the surface material mounting structure of the first embodiment has a first molding main body portion 40a and a protruding portion 40b protruding from the first molding main body portion 40a to the back surface side. The first molding main body portion 40a has a first inner peripheral surface facing portion 40c facing the inner peripheral surface 1b forming the opening 1a of the door main body 1, a front surface facing portion 40d connected to the first inner peripheral surface facing portion 40c and facing the front surface 1c of the door main body 1, an inclined surface portion 40e connected to the front surface facing portion 40d and inclined so that the distance between the inner peripheral surface 1b and the front surface 1b increases toward the back surface side, and a first glass plate facing portion 40f provided on the opposite side of the door main body 1 from the protruding portion 40b and facing the front surface of the glass plate 2.

[0013] The protruding portion 40b protrudes toward the rear surface side from between the inclined surface portion 40e and the first glass plate facing portion 40f. The protruding portion 40b has a base end protruding portion 40g connected to the first molding main body portion 40a, a tip end protruding portion 40h connected to the base end protruding portion 40g and protruding toward the rear surface side, and a substantially circular fitting portion 40i provided at the tip of the tip end protruding portion 40h.

[0014] The tip-side protrusion 40h has a narrower width in the in-plane direction of the glass plate 2 (hereinafter referred to as the in-plane direction) than the base-end protrusion 40g, and protrudes toward the back surface at a position farther from the inner circumferential surface 1b than the base-end protrusion 40g. The diameter of the substantially circular fitting portion 40i is larger than the width of the tip-side protrusion 40h in the in-plane direction. Furthermore, the fitting portion 40i has a slit 40j, which is open on the back surface side and extends in the out-of-plane direction of the glass plate 2 (hereinafter referred to as the out-of-plane direction), approximately at the center in the in-plane direction.

[0015] The second molding material 50 has a second inner peripheral surface facing portion 50a facing the inner peripheral surface 1b forming the opening 1a of the door body 1, a back surface facing portion 50b connected to the second inner peripheral surface facing portion 50a and facing the back surface 1d of the door body 1, a second glass plate facing portion 50c facing the back surface side of the glass plate 2, and a recess 50d provided between the second inner peripheral surface facing portion 50a and the second glass plate facing portion 50c and recessed into the back surface side.

[0016] The recess 50d has an arc shape that is open on the front surface side, and its diameter is approximately the same as or slightly larger than the diameter of the fitting portion 40i of the first molding material 40, and the width of the open portion of the recess 50d facing the front surface side is formed narrower than the diameter of the arc. In addition, the recess 50d is located on the rear surface side of the second glass plate facing portion 50c, and a first molding facing portion 50e that faces the tip side protrusion 40h of the first molding material 40 is provided between the recess 50d and the second glass plate facing portion 50c.

[0017] In the surface material mounting structure of the first embodiment, the first molding 4 and the second molding 5 are attached to the door body 1 from the front and back sides, respectively, the glass plate 2 is clamped between the first glass plate facing portion 40f and the second glass plate facing portion 50c, and the fitting portion 40i is fitted into and adhered to the recess 50d.

[0018] When the first molding 4 and the second molding 5 are attached to the door body 1, the glass plate 2 is sandwiched at its peripheral edge between the first molding 4 and the second molding 5, the first inner surface facing portion 40c and the second inner surface facing portion 50a are bonded opposite the inner surface 1b, the front surface facing portion 40d faces the front surface 1c of the door body 1, and the back surface facing portion 50b faces the back surface 1d of the door body 1.

[0019] Furthermore, the first molding 4 and the second molding 5 are fixed by driving in a needle 7 as a fastener that enters the door main body 1 from the first molding 4 and second molding 5 side. At this time, the needle 7 driven in from the second molding 5 side penetrates the extension portion 40b that is connected to the fitting portion 40i that is fitted in the recess 50d and enters the door main body 1. The fastener is not limited to a needle, and any fastener such as a nail or a screw may be used as long as it enters the door main body 1 from the first molding 4 and second molding 5 side and connects the first molding 4, second molding 5 and door main body 1.

[0020] 4(a), in the method for attaching the surface material of the first embodiment, first, the first molding 4 is placed on an assembly workbench T or the like with the protruding portion 40b facing upward, and the door body 1 is placed on the first molding 4 so that the first molding 4 is positioned in the opening 1a (first molding placing step). At this time, the first inner peripheral surface facing portion 40c faces the inner peripheral surface 1b, and the surface facing portion 40d abuts against the surface 1c of the door body 1.

[0021] Next, as shown in FIG. 4(b), the glass plate 2 is placed on the first molding 4 with the peripheral edge of the glass plate 2 abutting against the first glass-plate-facing portion 40f of the first molding 4 (face material placement step).

[0022] Next, as shown in FIG. 4(c), the second molding 5, to which adhesive 6 has been applied, is attached from above, and the fitting portion 40i is fitted into the recess 50d (adhesive application and face material holding step). At this time, as the fitting portion 40i enters the recess 50d, the fitting portion 40i elastically deforms to narrow the slit 40j. After entering the recess 50d, the fitting portion 40i recovers its elastic deformation and fits into the recess 50d, as shown in FIG. 4(d). At this time, some of the adhesive 6 applied to the recess 50d is extruded from the recess 50d and flows toward the inner circumferential surface 1b, remaining between the inner circumferential surface 1b and the first and second moldings 4 and 5. This bonds not only the fitting portion 40i and the recess 50d but also the first and second moldings 4 and 5 to the inner circumferential surface 1b.

[0023] Next, as shown in Fig. 4(e), needles 7 are driven obliquely with respect to the in-plane direction from the first molding 4 and the second molding 5 side toward the door body 1 using a stapler or the like. At this time, the needles 7 driven from the second molding 5 side penetrate the protruding portions 40b with the fitting portions 40i fitted in the recesses 50d, and are driven into the door body 1 from the inner peripheral surface 1b. By driving the needles 7, the movement of the first molding 4 and the second molding 5 in the in-plane direction and the out-of-plane direction is restricted.

[0024] According to the surface material mounting structure of the first embodiment, the first molding 4 and the second molding 5, which surround the peripheral edge of the glass plate 2 and are attached to the opening 1a of the door body 1, are attached from the front side of the door body 1 and the second molding 5 from the back side. The first molding 4 is attached from the front side of the door body 1, and the second molding 5 is attached from the back side. The first molding 4 and the second molding 5 are attached by engaging and locking the fitting portion 40i of the first molding 4 with the recessed portion 50d of the second molding 5. This allows the first molding 4 and the second molding 5 to be attached with their positions aligned to a predetermined position. Therefore, simply by engaging and locking the fitting portion 40i of the first molding 4 with the recessed portion 50d of the second molding 5, the first molding 4 and the second molding 5 can be aligned and the glass plate can be easily attached. This provides excellent manufacturability.

[0025] At this time, the fitting portion 40i of the first molding 4 and the recess 50d of the second molding 5 fit together, allowing the worker to recognize that the first molding 4 and the second molding 5 are aligned and securely joined, and that the glass plate 2 is held in place.

[0026] Furthermore, since the first molding 4 and the second molding 5 are attached by bonding with the adhesive 6, the glass plate 2 can be more reliably joined while being held by the first molding 4 and the second molding 5.

[0027] Furthermore, because the adhesive 6 is applied to the recess 50d of the second molding 5 into which the mating portion 40i of the first molding 4 is fitted, it is possible to more reliably join the first molding 4 and the second molding 5. Furthermore, because the portion to which the adhesive 6 is applied is the recess 50d, the application position of the adhesive 6 is clear, and the adhesive 6 can be reliably retained in the recess 50d before mating. This results in greater manufacturability.

[0028] Furthermore, since the first molding 4 and the second molding 5 are joined by the needles 7 that penetrate into the door body 1, the first molding 4 and the second molding 5 can be reliably joined to the door body 1 not only by adhesion but also by the needles 7. Furthermore, it is possible to restrict the movement of the first molding 4 and the second molding 5 that hold the glass plate 2 relative to the door body 1 in both in-plane and out-of-plane directions.

[0029] Furthermore, the needle 7 that enters the door body 1 enters through the second molding 5 and penetrates the protruding portion 40b of the first molding 4, so that the first molding 4 and the second molding 5 are reliably joined together and the first molding 4 and the second molding 5 can be more reliably attached to the door body 1.

[0030] Furthermore, according to the surface material attachment method of the first embodiment, the adhesive 6 is applied to the recess 50d of the second molding 5, so the application position of the adhesive 6 is clear and workability is good. Furthermore, because the adhesive 6 is applied to the recess 50d, the adhesive 6 remains within the recess 50d, allowing for more reliable adhesion to the mating portion 40i that is subsequently fitted. Therefore, simply by applying the adhesive 6 to the recess 50d and fitting the mating portion 40i into the recess 50d, the first molding 4 and the second molding 5 can be easily and reliably joined and the glass plate 2 can be attached. This provides better manufacturability.

[0031] In the above embodiment, an example was described in which the inner peripheral surface of the recess 50d into which the fitting portion 40i enters is simply arc-shaped. However, for example, as shown in FIG. 5, a protrusion 50f that enters the slit 40j may be provided at a portion of the recess 50d facing the slit 40j of the fitting portion 40i into which it enters. In this case, when the fitting portion 40i engages with the recess 50d, the protrusion 50f enters the slit 40j. Therefore, in the engaged state, the fitting portion 40i does not elastically deform so as to narrow the slit 40j. This more reliably maintains the engaged state. This makes it possible to hold the glass plate 2 more reliably.

[0032] In the above embodiment, an example has been described in which the first molding 4 and the second molding 5 are bonded with adhesive 6, but this is not limiting and they may also be bonded with, for example, double-sided tape 8. In the following description, first moldings or second moldings that are different from those in the above embodiment will be assigned numbers different from those in the above embodiment, and parts that are equivalent to those in the above embodiment will be assigned the same alphabet and will not be described again.

[0033] As shown in Figure 6, even in the modified example in which adhesion is achieved using double-sided tape 8, the first molding material 41 constituting the first molding 4 has, like the first molding material 40, a first molding main body portion 41a and a protrusion portion 41b protruding from the first molding main body portion 41a to the back side.

[0034] The first molding body 41a has a first inner peripheral surface facing portion 41c, a surface facing portion 41d, an inclined surface portion 41e, and a first glass plate facing portion 41f, similar to the first molding member 40. The protruding portion 41b also has a base end protruding portion 41g, a tip end protruding portion 41h, and a fitting portion 41i, similar to the first molding member 40.

[0035] The first molding material 41 differs from the first molding material 40 of the above embodiment in that the protruding portion 41b has a flat surface on the side opposite the inner circumferential surface that connects the tip-side protruding portion 41h and the mating portion 41i, and in that no slit is provided in the mating portion 41i.

[0036] Similar to the second molding material 50, the second molding material 51 has a second inner peripheral surface facing portion 51a, a back surface facing portion 51b, a second glass plate facing portion 51c facing the back surface side of the glass plate 2, and a recess 51d.

[0037] The second glass plate facing portion 51c has a recessed portion 51e formed on the inner circumferential surface 1b side and recessed toward the back surface side, and double-sided tape 8 is attached to the recessed portion 51e. Because the recessed amount of the recessed portion 51e is smaller than the thickness of the attached double-sided tape 8, the double-sided tape 8 attached to the recessed portion 51e protrudes toward the front surface side beyond the portion of the second glass plate facing portion 51c excluding the recessed portion 51e. Furthermore, the end of the recessed portion 51e on the inner circumferential surface 1b side is connected to the recessed portion 51d in a flat plane, and the width of the open portion of the recessed portion 51d facing toward the front surface side is formed narrower than the maximum width of the recessed portion 51d.

[0038] 7(e), in the surface material mounting structure in the modified example of the first embodiment, the first molding 4 and the second molding 5 are attached to the door body 1 from the front and back sides, respectively, the fitting portion 41i is fitted into the recess 51d, and the glass plate 2 is sandwiched between the first glass plate facing portion 41f and the second glass plate facing portion 51c. In addition, the peripheral edge of the glass plate 2 is adhered to the second molding 5 with double-sided tape 8.

[0039] When the first molding 4 and the second molding 5 are attached to the door body 1, the glass plate 2 is sandwiched at its peripheral edge between the first molding 4 and the second molding 5, with the first inner surface facing portion 41c and the second inner surface facing portion 51b facing the inner surface 1b, the front surface facing portion 41d facing the front surface 1c of the door body 1, and the back surface facing portion 51b facing the back surface 1d of the door body 1.

[0040] Furthermore, the needle 7 is driven into and fixed in the door body 1 from the first molding 4 and second molding 5 side. At this time, the needle 7 driven from the second molding 5 side penetrates the front end side protrusion 41h connected to the fitting portion 41i fitted into the recess 51d and enters the door body 1.

[0041] 7(a), in the method of attaching the surface material in the modified example of the first embodiment, first, the first molding 4 is placed on an assembly workbench T or the like with the protruding portion 41b facing upward, and the door body 1 is placed on the first molding 4 so that the first molding 4 is positioned in the opening 1a (molding placement step). At this time, the first inner peripheral surface facing portion 41c faces the inner peripheral surface 1b, and the surface facing portion 41d abuts against the surface 1c of the door body 1.

[0042] Next, as shown in FIG. 7(b), the glass plate 2 is placed on the first molding 4 with the peripheral edge of the glass plate 2 abutting against the first glass-plate-facing portion 41f of the first molding 4 (face material placement step).

[0043] Next, as shown in Fig. 7(c), the second molding 5 with the double-sided tape 8 attached to the recessed portion 51e is attached from above, and the fitting portion 41i is fitted into the recessed portion 51d (double-sided tape attachment and surface material holding step). At this time, as shown in Fig. 7(d), the double-sided tape 8 abuts against the peripheral edge of the glass plate 2, and the second molding 5 and the glass plate 2 are bonded together.

[0044] Next, as shown in Fig. 7(e), needles 7 are driven obliquely with a tacker or the like from the first molding 4 and second molding 5 sides toward the door body 1. At this time, the needles 7 driven from the second molding 5 side penetrate the protruding parts 41b and are driven into the door body 1 from the inner peripheral surface 1b with the fitting parts 41i fitted into the recesses 51d.

[0045] According to the surface material mounting structure and surface material mounting method in the modified example of the first embodiment, the second molding 5 has a recessed portion 51e where the double-sided tape 8 is attached in a position facing the glass plate 2, so the position where the double-sided tape 8 is attached is clear and the double-sided tape 8 can be easily attached. Furthermore, unlike adhesives that harden over time after application, the double-sided tape 8 can be attached in advance, making installation easy.

[0046] Second Embodiment The first molding material 42 in the surface material mounting structure of the second embodiment, like the first molding material 40, has a first molding main body portion 42a and a protrusion portion 42b protruding from the first molding main body portion 42a to the back side, as shown in Figures 8 and 9.

[0047] Similar to the first molding member 40, the first molding main body 42a has a first inner peripheral surface facing portion 42c, a surface facing portion 42d, an inclined surface portion 42e, and a first glass plate facing portion 42f. Similar to the first molding member 40, the protruding portion 42b has a base end protruding portion 42g, a tip end protruding portion 42h, and a fitting portion 42i. The first molding member 42 has a facing piece 42k that protrudes from the protruding portion 42b opposite the inner peripheral surface 1b and faces the first glass plate facing portion 42f with a gap in the out-of-plane direction, and the space between the first glass plate facing portion 42f and the facing piece 42k forms a peripheral end housing portion 42l that houses the peripheral end of the glass plate 2.

[0048] Similar to the second molding material 50, the second molding material 52 has a second inner peripheral surface facing portion 52a, a back surface facing portion 52b, a second glass plate facing portion 52c facing the back surface of the glass plate 2, and a recess 52d. The second glass plate facing portion 52c has a facing piece accommodating portion 52e formed on the inner peripheral surface 1b side and recessed on the back surface side, in which the facing piece 42k is arranged between the second molding material 52 and the glass plate 2.

[0049] In the surface material mounting structure of the second embodiment, the peripheral edge of the glass plate 2 is accommodated in the peripheral edge accommodating portion 42l of the first molding 4 and combined to form a single unit, and the first molding 4 and the second molding 5 are attached to the door body 1 from the front and back sides, respectively, and the fitting portion 42i is fitted into the recess 52d and bonded with adhesive 6.

[0050] When the first molding 4 and the second molding 5 are attached to the door body 1, the first inner surface facing portion 42c and the second inner surface facing portion 52a are adhered opposite the inner surface 1b, the front surface facing portion 42d faces the front surface 1c of the door body 1, and the back surface facing portion 52b faces the back surface 1d of the door body 1.

[0051] Furthermore, the needle 7 is driven into and fixed in the door body 1 from the first molding 4 and second molding 5 side. At this time, the needle 7 driven from the second molding 5 side penetrates the front end side protrusion 42h connected to the fitting portion 42i fitted into the recess 52d and enters the door body 1.

[0052] The method of attaching the surface material in a modified example of the second embodiment involves first attaching a first molding material 42 to each of the four sides of the peripheral edge of the glass plate 2, accommodating the peripheral edge of the glass plate 2 in the peripheral edge accommodating portion 42l of each first molding material 42, and joining adjacent first molding materials 42 together with a U-shaped pin (not shown).

[0053] 10(a), the first molding 4 is placed on an assembly workbench T or the like with the protruding portion 42b facing upward, and the door body 1 is placed on the first molding 4 so that the first molding 4 is positioned at the opening 1a. At this time, the first inner peripheral surface facing portion 42c faces the inner peripheral surface 1b, and the surface facing portion 42d abuts against the surface 1c of the door body 1.

[0054] Next, as shown in Fig. 10(b), the second molding 5 with adhesive 6 applied to the recess 52d is attached from above, and as shown in Fig. 10(c), the fitting portion 42i is fitted into the recess 52d. At this time, the facing piece 42k is accommodated in the facing piece accommodating portion 52e, and the adhesive 6 bonds the fitting portion 42i to the recess 52d and the first molding 4, second molding 5 and inner circumferential surface 1b.

[0055] 10(d), needles 7 are driven obliquely with a tacker or the like from the first molding 4 and second molding 5 sides toward the door body 1. At this time, the needles 7 driven from the second molding 5 side penetrate the protruding parts 42b and are driven into the door body 1 from the inner peripheral surface 1b with the fitting parts 42i fitted into the recesses 52d.

[0056] According to the surface material mounting structure and surface material mounting method of the second embodiment, the first molding 4 has a peripheral edge housing portion 42l that houses the peripheral edge of the glass plate 2. By housing the peripheral edge of the glass plate 2 in the peripheral edge housing portion 42l and combining it with the first molding 4 to form an integrated unit, it is no longer necessary to position the first molding 4 and the glass plate 2. The glass plate 2 can be mounted to the door body 1 simply by fitting the first molding 4 with the glass plate 2 and the second molding 5 together. This further improves manufacturability. Furthermore, since the peripheral edge of the glass plate 2 is housed in the first molding 4 when the glass plate 2 is moved during the mounting operation, it is possible to prevent damage to the peripheral edge of the glass plate 2.

[0057] In the second embodiment described above, an example has been described in which the first molding 4 and the second molding 5 are bonded with the adhesive 6, but this is not limiting, and as shown in Fig. 11, for example, they may be bonded with double-sided tape 8, as in the modified example of the first embodiment. Even in the modified example of the second embodiment in which they are bonded with double-sided tape 8, the first molding material 43 constituting the first molding 4 has, like the first molding material 41, a first molding main body 43a and a protrusion 43b that protrudes from the first molding main body 43a to the rear surface side.

[0058] The first molding main body 43a has a first inner peripheral surface facing portion 43c, a surface facing portion 43d, an inclined surface portion 43e, and a first glass plate facing portion 43f, similar to the first molding member 41. The protruding portion 43b also has a base end protruding portion 43g, a tip end protruding portion 43h, and a fitting portion 43i, similar to the first molding member 41. The first molding member 43 has a facing piece 43k that protrudes from the protruding portion 43b opposite the inner peripheral surface 1b and faces the first glass plate facing portion 43f with a gap in the out-of-plane direction, and the portion between the first glass plate facing portion 43f and the facing piece 43k forms a peripheral end housing portion 43l that houses the peripheral end of the glass plate 2.

[0059] Similar to the second molding material 51, the second molding material 53 has a second inner peripheral surface facing portion 53a, a back surface facing portion 53b, a second glass plate facing portion 53c facing the back surface side of the glass plate 2, and a recess 53d.

[0060] Second glass plate facing portion 53c has recessed portion 53e formed on the inner circumferential surface 1b side and recessed toward the back surface, recessed portion 53e facing facing piece 43k, and double-sided tape 8 is attached to recessed portion 53e. The recessed amount of recessed portion 53e is smaller than the combined thickness of the attached double-sided tape 8 and the facing piece 43k. Therefore, when fitting portion 43i and recess 53d fit together and recessed portion 53e faces facing piece 43k, double-sided tape 8 abuts against and is adhered to facing piece 43k. Furthermore, the end of recessed portion 53e on the inner circumferential surface 1b side is connected to recess 53d at a flat surface, and the width of the open portion of recess 53d facing the front surface side is formed narrower than the maximum width within recess 53d.

[0061] In the surface material mounting structure in the modified example of the second embodiment, as shown in Figure 12(d), the peripheral edge of the glass plate 2 is accommodated in the peripheral edge accommodating portion 43l of the first molding 4 and combined to form a single unit, the first molding 4 and the second molding 5 are attached to the door body 1 from the front and back sides, respectively, the fitting portion 43i is fitted into the recess 53d, and the second molding 5 is adhered to the opposing piece portion 43k of the first molding 4 with double-sided tape 8.

[0062] When the first molding 4 and the second molding 5 are attached to the door body 1, the first inner surface facing portion 43c and the second inner surface facing portion 53a face the inner surface 1b, the front surface facing portion 43d faces the front surface 1c of the door body 1, and the back surface facing portion 53b faces the back surface 1d of the door body 1.

[0063] Furthermore, the needle 7 is driven into and fixed in the door body 1 from the first molding 4 and second molding 5 side. At this time, the needle 7 driven from the second molding 5 side penetrates the front end side protrusion 43h connected to the fitting portion 43i fitted into the recess 53d and enters the door body 1.

[0064] The method of attaching the surface material in a modified example of the second embodiment is to first attach the first molding material 43 to each of the four sides of the peripheral edge of the glass plate 2, accommodate the peripheral edge of the glass plate 2 in the peripheral edge accommodation portion 43l of each first molding material 43, and then join adjacent first molding materials 43 together with U-shaped pins (not shown).

[0065] 12(a), the first molding 4 is placed on an assembly workbench T or the like with the protruding portion 43b facing upward, and the door body 1 is placed on the first molding 4 so that the first molding 4 is positioned at the opening 1a. At this time, the first inner peripheral surface facing portion 43c faces the inner peripheral surface 1b, and the surface facing portion 43d abuts against the surface 1c of the door body 1.

[0066] Next, as shown in Fig. 12(b), the second molding 5 with the double-sided tape 8 attached to the recessed portion 53e is attached from above, and as shown in Fig. 12(c), the fitting portion 43i is fitted into the recessed portion 53d. At this time, the double-sided tape 8 comes into contact with the facing piece 43k of the first molding 4, and the first molding 4 and the second molding 5 are adhered together.

[0067] 12(d), needles 7 are driven obliquely with a tacker or the like from the first molding 4 and second molding 5 sides toward the door body 1. At this time, the needles 7 driven from the second molding 5 side penetrate the protruding parts 43b and are driven into the door body 1 from the inner peripheral surface 1b with the fitting parts 43i fitted into the recesses 53d.

[0068] According to the surface material mounting structure and surface material mounting method in the modified example of the second embodiment, the second molding 5 has a recessed portion 53e for attaching the double-sided tape 8 at a position facing the facing piece 43k, so the position for attaching the double-sided tape 8 is clear and the double-sided tape 8 can be easily attached. Furthermore, unlike adhesives that harden over time after application, the double-sided tape 8 can be applied in advance, making the installation work easier. Furthermore, during the installation work of the glass plate 2, the peripheral edge of the glass plate 2 is housed in the first molding 4 when the glass plate 2 is moved, so it is possible to prevent damage to the peripheral edge of the glass plate 2.

[0069] In the above embodiment, an example was described in which the end accommodating portions 42l, 43l that accommodate the peripheral end portions of the glass plate 2 are provided in the first molding material 42, 43, but they may also be provided in the second molding material in the second embodiment.

[0070] In the above embodiment, the configuration has been described in which the pins 7 that enter the door body 1 from the first molding 4 and second molding 5 side are driven and fixed, but the pins 7 do not necessarily have to be driven in. Also, a configuration in which only the pins 7 that enter the door body 1 from the second molding 5 side are driven and fixed may be used.

[0071] In the above embodiment, a glass plate 2 was used as an example of a surface material, but this is not limited to this. For example, any surface material that can be attached with a molding to an opening provided in a plate-shaped member, such as a synthetic resin plate, a wooden plate, or a decorative plate, can be used.

[0072] The above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof. The present embodiment includes at least the following inventions.

[0073] Aspect 1: A panel mounting structure in which a panel is mounted by surrounding the peripheral edge of the panel with a first molding attached to one side of the panel and a second molding attached to the other side of an opening provided in the panel, wherein the first molding has a protrusion and the second molding has a recess into which the protrusion is fitted, the panel is engaged with the protrusion and the recess, and one of the first and second moldings is attached by adhesive to the other of the first and second moldings or to the panel.

[0074] According to the surface material mounting structure of aspect 1, the first and second moldings, which surround the peripheral edge of the surface material and are mounted to the opening of the plate-like member, are mounted such that the first molding is mounted from one side of the plate-like member and the second molding is mounted from the other side, and the protrusion of the first molding fits into and locks into the recess of the second molding, so that the first and second moldings can be mounted with their positions aligned to a predetermined position. Therefore, the surface material can be easily mounted by simply fitting and locking the protrusion of the first molding into the recess of the second molding, which results in excellent manufacturability.

[0075] At this time, the protrusion of the first molding fits into the recess of the second molding, allowing the worker to recognize that the first molding and the second molding have been aligned and attached.

[0076] Furthermore, since one of the first and second moldings is attached by being glued to the other of the first and second moldings or to the surface material, the adhesive area between the first and second moldings positioned in a predetermined position, or between the first or second molding and the surface material, can be secured, making it possible to securely attach the surface material.

[0077] Aspect 2: The surface material mounting structure according to Aspect 1, characterized in that an adhesive is applied to the recess.

[0078] According to the surface material mounting structure of aspect 2, adhesive is applied to the recessed portion of the second molding into which the protruding portion of the first molding fits, which allows the first molding and the second molding to be joined more reliably. Also, because the portion to which adhesive is applied is the recessed portion, the application position of the adhesive is clear and the adhesive can be positioned reliably. This results in superior manufacturability.

[0079] Aspect 3: A surface material mounting structure as described in Aspect 1, characterized in that the one molding is adhered to the other molding or the surface material with double-sided tape, and has a recessed portion for attaching the double-sided tape at a position opposite the other molding or the surface material.

[0080] According to the face material mounting structure of the third aspect, one molding has a recess for attaching double-sided tape at a position facing the other molding or face material, so the position for attaching the double-sided tape is clear and the double-sided tape can be easily attached, which makes it easier to manufacture.

[0081] Aspect 4: A surface material mounting structure as described in any one of Aspects 1 to 3, characterized in that at least one of the first molding and the second molding is joined by a fixing device that penetrates into the plate-like member.

[0082] According to the surface material mounting structure of aspect 4, at least one of the first molding and the second molding is joined by a fastener that penetrates into the plate-like member, making it possible to reliably join the first molding and the second molding to the plate-like member.

[0083] Aspect 5: The surface material mounting structure according to Aspect 4, wherein the fastener enters from the second molding and penetrates the protrusion.

[0084] According to the surface material mounting structure of aspect 5, the fastener that enters the plate-like member enters through the second molding and penetrates the protruding portion of the first molding, making it possible to more reliably join the first molding and the second molding.

[0085] Aspect 6: A surface material mounting structure according to any one of Aspects 1 to 5, characterized in that the first molding or the second molding has a peripheral end accommodating portion that accommodates the peripheral end of the surface material.

[0086] According to the panel mounting structure of aspect 6, the first molding or the second molding has a peripheral end accommodating portion that accommodates the peripheral end of the panel, and by accommodating the peripheral end of the panel in the peripheral end accommodating portion and combining it with the first molding or the second molding to form an integrated unit, manufacturability is further improved.

[0087] Aspect 7: A method for mounting a surface material to the surface material mounting structure described in Aspect 2, characterized by comprising the steps of: placing the first molding in the opening of the plate-like member; placing the peripheral edge of the surface material on the first molding; and applying adhesive to the second molding, so that the protrusion and the recess fit together to attach the second molding to the opening and hold the surface material.

[0088] According to the face material mounting method of aspect 7, the protrusion of the first molding and the recess of the second molding are fitted and locked together for mounting, making it possible to align the first molding and the second molding with each other in a predetermined position. Therefore, simply by fitting and locking the protrusion of the first molding and the recess of the second molding, the first molding and the second molding can be aligned and the face material can be easily mounted. Furthermore, because the protrusion and the recess are fitted together to lock the first molding and the second molding together, the worker can recognize that the first molding and the second molding are securely joined and the face material is held in place. This provides excellent manufacturability.

[0089] Aspect 8: A method for mounting a surface material for the surface material mounting structure described in Aspect 3, characterized by comprising the steps of: placing one of the moldings in the opening of the plate-like member; placing the peripheral edge of the surface material on the one of the moldings; and adhering the double-sided tape to the recess of the other molding, so that the protrusion and the recess fit together to adhere the other molding to the one of the moldings or the surface material and attach it to the opening to hold the surface material.

[0090] According to the face material mounting method of aspect 8, double-sided tape is applied to the recessed portion of the other of the first and second moldings, so the position where the double-sided tape is applied is clear and workability is good. Because the adhesive is used for bonding, there is no need to worry about hardening over time after application, as with adhesives, and handling is easy. Therefore, manufacturability is excellent.
