Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel, which is used for a top plate of a desk, a partition wall, or the like, and is provided with a frame member provided along an outer edge portion for reinforcement and the like, and a method for manufacturing the panel.

[0002]

2. Description of the Related Art As a panel used for a top plate or a partition of a desk, there is known a panel constituted by attaching face materials such as steel plates to the upper and lower surfaces of a core material.
This type is characterized in that it is lighter and has higher rigidity than a top plate using a particle board.

On the other hand, in such a structure, a frame member is arranged along the side edge portion for reinforcement. If the panel has a deformed edge portion composed of straight lines or curved lines, conventionally, the frame material is formed along the deformed edge portion. Was there. Furthermore, if the shape of this irregular edge becomes complicated, it will not be possible to deal with it by bending.Therefore, for the irregular edge, use a machined wood core instead of a frame material, or use an irregular edge. A frame material having a conforming shape has been manufactured in advance by drawing or the like.

[0004]

However, in any of the above cases, there is a problem that the processing equipment becomes large and the manufacturing cost and the manufacturing process increase. Specifically, for example, when a frame material is bent, a bending die and a manufacturing process required for bending are required. Further, in the case of carving out a wood core material, the wood core material is relatively expensive and a separate equipment for woodworking is required. Further, in the case of drawing, large-scale processing equipment and mold are required. As a result, although this type of panel in which the core material is sandwiched by face materials such as steel plates has the characteristics of being lightweight and highly rigid, there have been cases where irregular shaped edges cannot be formed from the viewpoint of cost. .

Moreover, since the above-mentioned processing equipment and mold are required for each panel having a different shape, it is difficult to standardize the production, and it is not possible to flexibly respond to the change of the outer shape of the panel, and the change of the panel shape is required. Each time, there was a problem that the mold and equipment had to be updated.

[0006]

[Means for Solving the Problems] In view of these problems,
INDUSTRIAL APPLICABILITY The present invention is one in which slits are continuously formed in a frame material of a channel-shaped panel and the frame material is bendable while maintaining sufficient strength, and the frame material can be easily arranged. It is an object of the present invention to provide an inexpensive panel that can flexibly cope with a change in the shape of a face material and a suitable manufacturing method thereof.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION That is, according to the present invention, a frame member curvedly arranged along at least a deformed edge portion, and face members provided above and below the frame member so as to sandwich the frame member, An edge member attached to the frame member, wherein the deformed edge portion forms a use edge portion, and the frame member is bent from a face plate portion and both side edges of the face plate portion. It is formed by including a bent piece and provided with the slits
Is formed by sheet metal processing of a thin metal plate.
Ri, and the state in which the slit width expanded or is reduced in bending piece at the curved portion of the profiled edge, together with being disposed along said profiled edges of said use edges with a curved, front
Make sure that the tip of the slit extends to the side edge of the face plate.
It is characterized by doing .

[0008] With such a structure, since the frame material can be curved along the irregular edge portion and the shape thereof can be determined, a bending die for bending the frame material and a processing facility are unnecessary. It is possible to manufacture easily and at low cost. Therefore, it is practically possible to form a deformed edge portion having a complicated shape in a panel of this type having structural strength. Further, since it is possible to flexibly deal with panels of various shapes and to change the shape, and the same frame material can be used, it is not necessary to manufacture a frame material for each panel as in the conventional case, and standardization of parts can be achieved. Further, even if such a frame member is curved, the dimension of the panel in the thickness direction does not change, and the dimensional accuracy of the irregular edge portion in the thickness direction of the panel can be easily improved.

As a concrete embodiment of the frame member, the frame member comprises an upright plate which is a face plate portion, and an upper piece and a lower piece which are bent pieces bent and extended from respective side edges thereof. However, a metal thin plate in the shape of a channel having an opening on its side can be used. In such a case, as a frame material that can be suitably applied to a flat panel typified by a desk top plate or the like, one in which slits are provided in the upper piece and the lower piece in phase with each other is used. Can be mentioned.

As an embodiment capable of coping with the deformed edge portion curved up and down, the frame member includes an upright plate and upper and lower pieces bent and extended from respective side edges thereof. However , it is made of a thin metal plate in the shape of a channel having an opening on the side, and is either the upper piece or the lower piece.
When a slit is provided across the standing plate from one side
Both, the other of the upper piece or the lower piece in the curved portion
Is equivalent to the face plate portion .

The panel is three-dimensionally curved,
In order to accommodate the profiled edges that are curved so as to twist, it is desirable to provide the upper and lower pieces with slits that are out of phase with each other. In particular, in order to achieve the purpose of reducing the amount of use of the edge member when the edge member is poured and molded, it is preferable that the opening is opened inward.

To improve the mounting strength of the edge member,
For those that have the opening of the frame material opened to the outside, or for the frame material,
It is preferable to provide an engaging claw that engages with the edge member. In order to be able to bend any part and to flexibly cope with panels of various shapes, it is preferable that the slits be continuously provided between both ends of the frame member. On the other hand, in order to shorten the manufacturing time and the process as much as possible, it is preferable that the slits are provided only in a portion corresponding to the curved portion of the deformed edge portion.

In still another embodiment, the frame member is in the shape of a square pipe, and one of the curved portions has a face plate portion and the other three surfaces have bent pieces. As a method of manufacturing the above-described panel for simultaneously performing molding and mounting of the edge member to reduce the manufacturing process and improve the appearance of the panel, after disposing the frame member between the face materials, at least the frame member is removed. An example is one in which the edge forming mold is arranged at a predetermined distance, and resin is injected into the gap formed between the frame material and the edge forming mold to form the edge member.

In order to improve the attachment strength of the edge member and simplify the structure of the frame member, it is desirable that the edge member be formed of a resin material having adhesiveness. As a preferable configuration for using the driven-in type edge member, the edge member includes an edge body and a locking ridge protruding in the longitudinal direction from an attachment surface of the edge body to the frame material. It is a thing, on the standing plate that constitutes the frame material,
An example is one that has an edge member mounting groove extending along its longitudinal direction and capable of engaging with the locking ridge, and having groove slits on both side plates and bottom plate constituting the edge member mounting groove. .

In this case, in order to prevent the edge member driven into the frame member from slipping off, the width dimension of the edge member mounting groove may be set so as to increase toward the bottom. In order to reduce the number of members and to facilitate the manufacture, it is preferable that the side plates and the bottom plate that form the edge member mounting groove be formed integrally with the upright plate by bending.

In order to easily and more firmly attach the edge member to the frame member by devising the shape of the edge member, the locking ridges constituting the edge member have saw teeth on both sides thereof. It is preferable that it is provided with a locking portion. In order to absorb the mounting position error of the frame material with respect to the face material so as not to impair the appearance, the edge body that constitutes the edge member is the attachment surface to the frame material, and It is desirable that the splicing protrusions that are spliced to the edge be integrally provided.

As a preferable material for the edge member, a resin material which can be slightly elastically deformed may be used.

[0018]

The core material 2 is a paper-made plate member having a honeycomb structure, for example. Each of the upper and lower steel plates 31, 32 is made of a thin steel plate having a plate thickness of about 0.6 mm, for example, and is set to a size slightly larger than the core member 2 in plan view. As shown in FIGS. 5 and 6, the left and right edges and the non-use edge are integrally provided with a laterally bent portion 3a and a rear bent portion 3b which are bent inward. It is designed to exert a predetermined strength against bending.

The rear edge base 8 is made of a channel-shaped thin metal plate with the opening portion facing inward, and a ridge 8a extends outward from the erected portion along the longitudinal direction. Has been formed. The ridges 8a are for engaging and attaching a rear edge member 5B described later. Frame material 4
In particular, as shown in FIG. 7 and FIG. 8 (this figure is a developed view), the standing plate 4c, which is a face plate portion having substantially the same width dimension as the thickness dimension of the core material 2, and both side edges 4c1 thereof. A thin metal plate such as steel having a channel shape composed of an upper piece 4a and a lower piece 4b, which are bent pieces integrally with each other, and is formed by sheet metal working from the expanded state shown in FIG. 8, for example. Is. Thus, the upper piece 4a and the lower piece 4b are provided with slits 6 in phase with each other. The slit 6 has a triangular shape that is opened at the tips of the upper piece 4a and the lower piece 4b, and has a width narrowing toward the base end. It is provided. The tip 6a of each slit 6 extends to the side edge portion 4c1 of the standing plate 4c, and the standing plate 4c bends along a virtual bending line L connecting the tips 6a of the upper and lower slits 6 having the same phase. However, the frame member 4 can be freely curved so as to form a polygon in plan view as a whole. In this embodiment, as shown in FIG. 9, two types of frame members 4 (A) and 4 (B) having different lengths are prepared, and one frame member 4 (A) is curved to be used edge portion 1c. The second frame member 4 (B) is arranged along the straight edge B while remaining linear in plan view. The opening 4d of the frame member 4 is arranged so as to open inward.

To specifically dispose the frame members 4 (A) and 4 (B), for example, the following process is performed. First, the lower steel plate 32
Stick the core material 2 on the upper surface of the. Simultaneously with or before or after this, the frame member 4 (A) with the opening 4d thereof facing inward, and the tips of the upper and lower pieces 4a, 4b of the core member 2
The surface is abutted on the side surface 2a on the use end side, that is, along the deformed edge A, and is appropriately curved, and is attached to the upper surface of the lower steel plate 32. Similarly to this, the frame member 4
(B) is also adhered along the straight edge B. Then, the upper steel plate 3 from above the core material 2 and the frame materials 4 (A) and 4 (B)
Paste 1 and press. In the present embodiment, as shown in FIG. 4, the upper and lower steel plates 31,
The distance dimension 3t of the portion of the protruding portion 32 from the core material 2 is set to be substantially equal to the length dimension 4t of the upper piece 4a and the lower piece 4b of the frame member 4.

In this way, the frame member 4 is formed on the outer surface of the standing plate 4c and the steel plate 3 without using a positioning jig, a bending die, or the like.
The used edges of 1, 32 can be attached along the profiled edge A. As shown in FIG. 9, in this state, in the curved portions P1 and P2 of the deformed edge portion A, each slit 6 has its width 6t enlarged, and in the curved portion P3, its width 6t is reduced. ing.

To attach each edge member 5, 5A, 5B to the panel body 1 thus constructed, refer to FIGS.
As schematically shown in FIG. First, the front edge member 5 is attached to the panel body 1T. To this end, as shown in FIG. 10, first, a wood material or the like is carved out, and a master mold MK having the same shape as the state in which the front edge member 5 is attached to the panel body 1 is created. At that time, an unillustrated grain film is attached to the surface of the front edge portion MK5 of the master mold MK. And a wooden frame K having the same depth as the thickness of the master mold MK5
The master mold MK is put in K, and a lid KK1 having a urethane inlet UR is attached to the master mold MK in a wooden frame KK.

Then, as shown in FIG. 11, liquid urethane is injected from the urethane injection port UR. At this time, in order to prevent air bubbles from entering, it is preferable to perform urethane injection while discharging air from an air hole (not shown) provided above the wooden frame KK with the injection port UR side facing down. After the injected liquid urethane has hardened, the lid KK is removed and the master mold M
Take out K. As shown in FIG. 12, the remaining urethane becomes the edge forming mold EK.

Next, a mold release agent is applied to the edge forming frame EK, and as shown in FIGS.
The above-mentioned panel body 1T is arranged in K with a gap AR corresponding to the width of the front edge member 5. Then, the panel body 1T is sealed in the edge forming frame EK with a lid (not shown), and liquid urethane is injected into the gap AR from an inlet (not shown).
Inject.

After the injected urethane is cured and the front edge member 5 is formed, the lateral edge member 5A and the rear edge member 5B, which have been manufactured in advance, are taken out by opening the lid, and the like. The panel 1 is completed by affixing to the left and right edges 1b and the non-use end edge 1a, respectively. According to the panel 1 according to the present embodiment configured as described above, since the frame member 4 is freely curved, the frame member 4 can be arranged directly along the deformed edge portion A.
Therefore, processing equipment such as a bending die can be dispensed with, the manufacturing cost can be kept low, and the manufacturing can be simplified. Furthermore, since it is possible to flexibly respond to panels of various shapes and shape changes, and since the same frame material can be used, it is not necessary to manufacture a frame material for each panel with a different shape as in the past, and parts and production Standardization of equipment can be achieved. As a result, the steel plates 31, 3 are formed on the upper and lower surfaces of the core material 2 as in the present embodiment.
In the panel 1 of the type in which 2 is attached, it is practically possible to form the irregular edge portion A from the viewpoint of cost and the like.

As for the front edge member 5, since the injection-integrated molding is performed in which the mounting to the panel body 1T is performed at the same time as the molding, the manufacturing process can be reduced. Moreover, since the step between the decorative plate 33 and the front edge member 5 can be eliminated, the appearance can be made very good. Moreover, since the material thereof is urethane resin having adhesiveness, the front edge member 5 can be adhered to the decorative plate 33 and the mounting strength thereof can be improved. Since there is no gap between the plate 33 and the plate 33, the appearance can be improved. further,
The front edge member 5 is arranged so as to cover the frame member 4, and
Since it is completely hidden, even if there is some error in the attachment of the frame member 4, the assembly can be simplified.

Particularly in this embodiment, since the frame member 4 is arranged with the opening 4d thereof being opened inward, urethane is provided as compared with the case where the opening 4d is arranged outward. The amount of resin used can be reduced. Also, each slit 6
Since the portion formed with is up to the side edge portion 4c1 of the standing plate 4c, leakage of the liquid resin from the slit 6 to the inside which occurs when the edge member 5 is formed by the injection method as in the above embodiment. It can be prevented as much as possible.

The present invention is not limited to the above-mentioned embodiment, but various modifications can be made. However, in the following, members corresponding to those in the above-described embodiment are designated by the same reference numerals. For example, referring to the frame member 4, although two types are used in the present embodiment, one frame member that can be disposed in the entire use edge portion 1c may be used. Further, as shown in FIG.
To the curved portion P1, P2 of the irregular edge A,
You may provide only in the part corresponding to P3. In this case, although it is not possible to deal with a panel having a completely different edge shape, the number of slits 6 can be reduced, so that the manufacturing time and the process can be shortened.

Further, as shown in FIG. 17, a slit 6 may be provided across the standing plate 4c from either the upper piece 4a or the lower piece 4b of the frame member. In this case, the other of the upper piece 4a or the lower piece 4b in the curved portion corresponds to the face plate portion, and either one of the upper piece 4a or the lower piece 4b and the standing plate 4c correspond to the bent piece. However, in the case of such a structure, as shown in FIG.
It is possible to correspond to the panel 100 having a vertically curved shape. Further, as shown in FIG. 16, the phases of the slits 6 provided on the upper piece 4a and the lower piece 4b may be shifted. With such a configuration, the virtual bending line L connecting the tips 6a of the corresponding slits 6 has an angle inclined with respect to the longitudinal direction of the frame member 4, so that the frame member 4 is moved along the virtual bending line L1. When bent, the frame member 4 is three-dimensionally twisted and curved as a whole. Therefore, it is possible to deal with the deformed edge portion A1 that is three-dimensionally twisted.

Of course, in addition to this, it is needless to say that a configuration in which the intervals and positions of the slits 6 are changed so as to be optimal for various irregular edge shapes can be considered. Further, as shown in FIG. 19, the frame member 4 is arranged with the opening 4d facing outward, and the edge member 5 is held so as to enter the inside of the opening 4d. Is also good. With such a structure, the mounting strength is further increased.

Further, in the above-described embodiment, only the front edge member 5 is molded by injection, but all the parts including the lateral edge member 5A and the rear edge member 5B may be molded by injection. Furthermore, the material of the resin is not limited to the urethane type. For example, an olefin-based material such as polypropylene or TPO (thermo plastic olefin) or an ethylene-based material such as PET resin or polyethylene may be used. However, in the case of a material having no adhesiveness such as an olefin-based material or an ethylene-based material, it is necessary to devise a method for holding the edge member. To this end, as shown in FIG. 20, an edge member 5 (not shown in the figure) formed of TPO or the like is engaged with the opening edge of the opening 4d of the frame members 4 (A) and 4 (B). In order to be able to hold it, the opening 4d is arranged outward, and the engagement claws 92 for retaining are extended from the tips of the upper piece 4a and the lower piece 4b of the frame member 4 toward each other. It is possible to send it out. In this case, it is preferable that the frame member 4 (B) along the straight edge portion be provided with the engaging claws 92 intermittently. This is because, for example, when the engaging claws 92 are continuously provided, the edge member 5 is easily elastically deformed downward when a load is applied to the edge member 5 from above, and the edge member 5 and the upper edge of the edge member 5 are easily deformed. This is because a gap is formed between the outer edge of the decorative plate 33 (not shown in the figure), which is not desirable in appearance. For the same purpose as this, for example, as shown in FIG. 21, the frame member 4 is disposed with its opening 4d facing inward and the standing plate 4c is projected outward. The compound nail 93 may be provided.

Further, as shown in FIG. 22, the bottom raising material PP may be attached to the standing plate 4c of the frame member 4, and the edge member 5 may be formed around this. By doing so, the amount of resin used to form the edge member 5 can be reduced. For the same purpose, as shown in FIG. 23, the outer end 4G of the frame member 4 opened toward the inside is the upper and lower steel plates 3
You may make it located outside the outer ends 31G and 32G of 1 and 32. With this, the attachment strength of the edge member 5 can be improved.

Further, as shown in FIG. 24, a frame member 304
In the shape of a square pipe, and the three sides 30
4a, 304b, 304d and slit 306
Alternatively, the other surface 304c may be refracted. With such a structure, the strength of the frame member 304 can be reasonably improved. Further, the surface 304d serves as an engaging claw, which also serves to prevent the edge member from coming off. In addition,
In this case, the one surface 304c in the curved portion corresponds to the face plate portion, and the three surfaces 304a, 304b, 304d.
Corresponds to a bent piece.

On the other hand, in order to utilize the driving type edge member 5, the following modified examples are conceivable as shown in FIGS. That is, in this panel, the edge member 5 extends over the entire length from the attachment surface of the edge body 51 attached to the frame material 4 along the longitudinal direction, to the edge body 51 that forms an edge by contacting with the outer surface of the frame material 4. It is made of a soft resin that is elastically deformable to some extent and integrally includes a locking projection 52 that is projected. Then, the opening 4d of the frame member 4
The standing plate 4c, which is a face plate portion, is arranged along the edges of the upper and lower steel plates 31, 32 and the decorative plate 33 so as to open inwardly, while the standing plate 4c is provided near the center in the vertical direction. , A bottomed edge member mounting groove 7 extending along the entire length along the length thereof is integrally provided by bending.
The edge protrusion 5 is driven into the edge member mounting groove 7 and engaged therewith, so that the edge member 5 is attached to the frame member 4. The frame member 4 is provided with an upright plate 4c which is a face plate portion and upper and lower pieces 4a and 4b which are bent pieces bent and extended from respective side edges 4c1 thereof, as in the above embodiment. The upper piece 4a and the lower piece 4b are provided with slits 6 which are opened at the front end and whose width becomes narrower toward the base end, at the same intervals in phase.

In this modification, the upper and lower side plates 71 and 72 and the bottom plate 73 forming the edge member mounting groove 7 are
The groove slit MS is provided so as to have the same phase as the slit 6 provided on the upper and lower pieces 4a and 4b. Each groove slit MS has a standing plate side edge 7 on one side plate 71, as is clear from the partial development view of the frame member 4 shown in FIG. 32 in particular.
1a to the standing plate side end edge 72a of the other side plate 72
And is provided orthogonally to the longitudinal direction of the frame member 4 so as to straddle the bottom plate 73, and the width of each side plate 71, 72.
Is the smallest at the edges 71a, 72a on the standing plate side of
It is set to be the largest in the center of the bottom plate 73. In addition, the upper and lower side plates 71, 72 are arranged so that the width dimension of the edge member mounting groove 7 increases toward the bottom.
Is tilted.

On the other hand, the locking projection 5 which constitutes the edge member 5
2 is a locking portion 5 having a sawtooth-shaped cross section on both upper and lower surfaces thereof.
2a is integrally provided, and the width dimension thereof, that is, the distance dimension from the tip of the locking portion 52a provided on one side surface to the tip of the locking portion 52a provided on the other side surface is It is set to be slightly larger than the opening width dimension of the edge member mounting groove 7. Therefore, the locking projection 52 is driven into the edge member mounting groove 7 while the locking portion 52a is slightly elastically deformed. Also,
The edge body 51 that constitutes the edge member 5 has a pair of splicing protrusions 51a that are splice surfaces to the frame member 4 and that are spliced from the upper and lower edges of the upper and lower steel plates 31, 32 and the decorative plate 33. Each of them is integrally projected.

According to the structure of this modification, even if the edge member mounting groove 7 is formed in the frame member 4 in order to use the driven-in type edge member 5, the bottom plate 73 and both side plates 71, 7 thereof are formed.
By providing the groove slit MS in the frame 2, the frame member 4 can be freely curved, and the same effect as that of the above-described embodiment can be obtained. The edge member mounting groove 7 is
Since the width dimension thereof widens toward the bottom, it is possible to prevent the driven edge member 5 from coming off easily, and the frame member 4 can firmly hold the edge member 5. In addition to this, in this modified example, since the locking projections 52 which form the edge member 5 are provided with the serrated locking portions 52a on both side surfaces thereof, not only is it easy to drive and engage, but also the locking projections are temporarily engaged. Fitting locking ridge 52
, The engaging portion 52a is elastically deformed a little and the elastic return force makes close contact with the edge member attachment groove 7, so that the edge member 5 is extremely firmly attached to the frame member 4 together with the shape of the edge member attachment groove 7. It will be possible to install. further,
The splicing protrusions 51a are used for the upper and lower steel plates 31, 32 and the decorative plate 33.
Therefore, even if the mounting position of the frame member 4 with respect to the upper and lower steel plates 31 and 32 is displaced in the projecting direction, if the mounting protrusion 51a is within the projecting dimension, the mounting error is caused by the edge. By mounting the member 5, it is possible to prevent absorption and deterioration of the appearance.

Furthermore, in the above-mentioned embodiments and modifications, the panel used for a top plate such as a desk has been described. However, even if a similar panel is applied to a partition wall or the like, similar operational effects can be obtained. it can. In addition, the present invention is not limited to the illustrated examples described above, and various modifications can be made without departing from the spirit of the present invention.

However, if the slits are provided in the upper piece and the lower piece so as to be out of phase with each other, the panel is curved three-dimensionally and the deformed edges are curved so as to be twisted accordingly. Can correspond to. Further, if the opening is opened inward, it is possible to reduce the usage amount of the edge member when the edge member is injected and molded. Further, if the opening is opened to the outside, or if the engaging claw that engages with the edge member is provided on at least one of the upper piece and the lower piece of the frame material, the attachment strength of the edge member is increased. Can be improved.

If slits are continuously provided between both ends of the frame member, the panel can be flexibly adapted to any shape, and its length can be adjusted by cutting. Can contribute more. If the slits are provided only in the portion corresponding to the curved portion of the deformed edge portion, the number of slits is reduced, so that the manufacturing time and the process can be shortened.

If the frame member is in the shape of a square pipe and one of the curved portions is a face plate portion and the other three surfaces are bent pieces, the strength of the frame member is reasonably improved. be able to. Further, of the other three surfaces, the surface facing the face plate portion prevents the edge member from coming off, and the mounting strength of the edge member can be improved.
Further, after arranging the frame member between the face members, the edge forming mold is arranged at least a predetermined distance from the frame member, and the resin is provided in the gap formed between the frame member and the edge forming mold. By adopting the manufacturing method that forms the edge member by injecting, it is possible not only to simplify the manufacturing process by molding and mounting the edge member at the same time, but also to reduce the step generated on the mounting end face of the edge member. Therefore, the appearance of the panel can be improved. In this case, if the edge member is made of a resin material having adhesiveness, the attachment strength can be made sufficient without the above-mentioned device for improving the attachment strength of the frame material.

The edge member is provided with an edge main body and a locking ridge protruding in the longitudinal direction from the attachment surface of the edge main body to the frame material, and the standing plate constituting the frame material. The edge member mounting groove that extends along the longitudinal direction and that can engage with the locking projection, and the groove slits are provided on both side plates and the bottom plate that form the edge member mounting groove. By expanding and contracting the width of the groove slit, the frame material can be freely curved, and the driving-type edge member can be preferably used.

In this case, if the width dimension of the edge member mounting groove is set so as to increase toward the bottom, the edge member driven into the edge member mounting groove can be prevented from coming off easily, and the edge member can be attached to the frame member. Can be firmly held.
If both side plates and the bottom plate forming the edge member mounting groove are formed by bending integrally with the standing plate, it is possible to contribute to the reduction of members and the simplification of manufacturing.

If the locking projections forming the edge member are provided with serrated locking portions on both side surfaces thereof, not only can the driving engagement be facilitated, but the locking portions once engaged are less likely to come off. In addition to the shape of the edge member mounting groove, the edge member can be mounted extremely firmly to the frame member. If the edge body constituting the edge member is a surface to be attached to the frame member and integrally formed with a splicing ridge that splices from the upper and lower edges of the edge member to the edge of the face material, Even if the frame member protrudes with respect to the face member, the mounting position error can be absorbed and the external appearance can be prevented from being impaired as long as it is within the protrusion dimension distance of the splicing protrusion.

If the edge member is made of a resin capable of being slightly elastically deformed, the elastic deformation can be utilized, so that the mounted state can be further improved.
