Japanese Unexamined Patent Publication No. 2015-0593778

However, the width dimension of the commercially available decorative sheet is limited to several ways, and even if the maximum width decorative sheet is used, depending on the depth and / or thickness dimension of the shelf board, one decorative sheet can be used for the surface. It may not be possible to cover from the front to the back of the wood. In this case, two decorative sheets are used so that the seam is located on the back surface of the shelf board in a relatively inconspicuous place, that is, on the back surface side of the shelf board provided at a particularly high position. However, the seams are visible, and the colors and patterns of the two decorative sheets do not match at the seams, which greatly impairs the design.

Therefore, the problem to be solved by the present invention is to provide a shelf board which gives high designability and has sufficient strength while using two decorative sheets.

In order to solve this problem, the invention according to claim 1 of the present application is a plywood or single plate laminated material in which single plates are laminated in a direction orthogonal to the thickness direction of the shelf plate, and a front of the plywood or single plate laminated material. From the surface of the shelf board body to the front wood end surface formed by the core material having the front wood mouth material adjacent to the front wood mouth material and the front surface material and the back surface material attached to the front and back of the core material. In a shelf board in which a decorative sheet is attached to the back surface through the above, (1) at the position where the plywood or single plate laminated material exists, the back surface material is penetrated from the back surface side of the shelf board body to the plywood or single plate laminated material. A concave groove is formed in the width direction of the shelf board body having a depth of penetration , and (2) the decorative sheet is composed of two decorative sheets, a front side decorative sheet and a back side decorative sheet, and the front side decorative sheet. Wraps from the front surface of the shelf board body through the front end surface to the back surface, reaches the concave groove position, is attached to the front surface, the front end surface, and the front end side area of the back surface, and the tip portion is folded into the concave groove. The back side decorative sheet is attached to the back end rear end side region that reaches the concave groove from the rear end of the shelf board main body, and the tip portion thereof is folded into the concave groove, and (3) folded into the concave groove. It is characterized in that the joint material is fitted into the concave groove so as to push the tip portion of the front side decorative sheet and the back surface side decorative sheet.

The invention according to claim 2 of the present application is characterized in that, in the shelf board according to claim 1, the front wood end material , the front surface material, and the back surface material are all formed of a wood fiber board .

In the invention according to claim 3 of the present application, in the shelf board according to claim 1 or 2 , the surface of the joint material fitted in the concave groove is the lower surface of the front surface side decorative sheet and the back surface side decorative sheet. It is characterized by having a thickness that is located higher and is buried in the concave groove .

According to the invention of claim 1, two decorative sheets, a front side decorative sheet and a back side decorative sheet, are used as the decorative sheets to be attached from the front surface of the shelf board body to the back surface through the front end surface. Even if it is not possible to cover them with one decorative sheet, makeup can be applied to the front surface of these with a decorative sheet. Further, since the end portion that becomes the joint of the two decorative sheets is folded into the concave groove formed on the back surface side of the shelf board body and the joint material is fitted from above, the joint between the decorative sheets can be formed. It is inconspicuous and can prevent the decorative sheet from peeling off.

Further, since a concave groove is formed on the back surface side of the shelf board body at a position where a plywood or a single board laminated material in which the single board is laminated in a direction orthogonal to the thickness direction of the shelf board exists, the shelf is formed by forming the concave groove. Sufficient strength can be ensured by minimizing the decrease in strength of the plate body.

According to the invention of claim 2 , since both the front wood mouth material and the front and back materials are formed of a wood fiber board having excellent workability, the front and back corners of the front wood mouth surface of the shelf board are chamfered into a curved surface. It is easy to do.

According to the invention of claim 3, when the shelf board installed substantially horizontally is viewed from diagonally below, the joint material is buried in the concave groove, so that it is difficult to expose the shelf board, and the back surface side decorative sheet has a back surface. It is possible to give an appearance as if the side decorative sheets are continuous, and further improve the design .

It is a side view sectional view of the shelf board by one Embodiment (Example 1) of this invention. It is an enlarged view of part A in FIG. It is a process diagram which shows an example of the manufacturing process of this shelf board (the detailed structure of a shelf board main body is not shown). It is a side view sectional view of the shelf board by another embodiment (Example 2) of this invention.

Hereinafter, the present invention will be described in detail with reference to examples.

A shelf board according to an embodiment of the present invention (Example 1) will be described with reference to FIGS. 1 and 2. The main body 11 of the shelf board 10 is a paper core 12 such as a honeycomb core, a single plate laminated body 13 adjacent to the front of the paper core 12, and a front of the shelf board main body 11 adjacent to the front of the single plate laminated body 13. A core material 16 having a front wood end material 14 for providing a wood end surface 11b and a rear core material 15 adjacent to the rear of the paper core 12 and a core material 16 are attached so as to cover the front surface and the back surface of the core material 16, respectively. It is composed of a front surface material 17 and a back surface material 18. The single plate laminated body 13 is a plywood or a single plate laminated material (LVL), and is arranged so that the laminated direction of the single plates substantially coincides with the direction orthogonal to the thickness direction of the shelf plate 10.

The front wood end material 14 is formed of a wood fiber board such as MDF. The back core material 15 plays a role of stopping the movement of the paper core 12 in the depth direction inside the shelf plate 10, and a plywood or a single plate laminated material is preferably used as the material thereof. In this embodiment, the front and back corners 11c and 11d of the front end surface 11b of the shelf board main body 11 are formed in a curved surface.

In this embodiment, the front surface material 17 and the back surface material 18 are assumed to have a length that projects further rearward from the rear end of the core material 16, and a recess 19 is formed between them. The recess 19 provides a space for inserting a shelf support (not shown) installed substantially horizontally on the wall surface (not shown), and a shelf board 10 held by hand at substantially the same height as the shelf support is placed on the wall surface. The shelf support is accommodated in the recess 19 and fixed by a fixing means (not shown) such as an adhesive.

At the position where the single plate laminated body 13 exists, the concave groove 20 having a depth that penetrates the back surface material 17 and enters the single plate laminated body 13 from the back surface 11c side of the shelf plate main body 11 is in the width direction of the shelf plate main body 11. It is formed over.

A decorative sheet is attached to the front surface 11a (the surface of the surface material 17), the front end surface 11b (the front surface of the front end material 14) and the back surface 11c (the front surface of the back surface material 18) of the shelf board main body 11. Although it is necessary to apply makeup, in this embodiment, two decorative sheets, that is, two decorative sheets, a front side decorative sheet 21 and a back side decorative sheet 22, are used.

The front surface side decorative sheet 21 wraps around from the front surface 11a of the shelf board main body 11 to the back surface 11c via the front end surface 11b and reaches the concave groove 20, and reaches the front end side portions of the front surface 11a, the front end surface 11b and the back surface 11c. It is attached, and its tip portion 21a is folded into the concave groove 20. The back surface side decorative sheet 22 reaches the concave groove 20 from the rear end of the shelf board main body 11 and is attached to the rear end side portion of the back surface 11c, and the front end portion 21a is folded into the concave groove 20. ..

Then, the joint material 23 is fitted into the concave groove 20 so as to push the end portions 21a, 22a of the front side decorative sheet 21 and the back surface side decorative sheet 22 folded into the concave groove 20 toward the back of the concave groove 20. It has been. The joint material 23 has a width dimension substantially the same as the groove width of the concave groove 20, and is an optional material such as synthetic resin as a long material extending substantially the same width as the shelf board main body 11 like the concave groove 20. It is formed. The thickness of the joint material 23 is arbitrary, but as shown in the illustrated embodiment, when the joint material 23 is pushed close to the groove bottom 20a of the concave groove 20, the front surface thereof is the front surface side decorative sheet 21 and the back surface side decorative sheet. It is preferable that the thickness is such that it is located above the lower surface of 22 and is buried in the concave groove. As a result, when the shelf board 10 installed substantially horizontally is viewed from diagonally below, the joint material 23 is buried in the concave groove 20 to make it difficult to expose, and the back side decorative sheet 22 is attached to the front side decorative sheet 21. Since it gives an appearance as if it is continuous, the design can be further improved.

An example of the manufacturing process of the shelf board 10 will be described with reference to FIG. As described above, a plate-shaped shelf in which the front surface material 17 and the back surface material 18 are attached to the front and back surfaces of the core material 16 composed of the paper core 12, the single plate laminate 13, the front wood end material 14 and the rear core material 15. A plate body 11 is prepared ((a) in the figure), and the front and back corner portions 11d and 11e of the front end surface 11b are chamfered to form a curved surface, and at a position where the single plate laminate 13 exists. From the back surface 11c side, a concave groove 20 having a depth that penetrates the back surface material 18 and enters the single plate laminate 13 is formed over the width direction (FIG. 3B). Since the front wood end surface 11b is formed of the front wood end material 14 made of a wood fiber board such as MDF, which is easy to process, the front and back corner portions 11d and 11e can be easily chamfered.

Next, the shelf board main body 11 is turned upside down so that the back surface 11c faces upward, and the back surface side decorative sheet 22 is attached to the region reaching the concave groove 20 from the rear end of the back surface 11c, and the tip end portion 22a is attached. Fold it into the recess 20 (Fig. 3C). Alternatively, the tip portion 22a may simply be projected into the opening of the concave groove 20. Since the back surface material 18 is made of a wood fiber material such as MDF having a smooth surface, the back surface side decorative sheet 22 can be attached without peeling off.

In this way, the shelf board main body 11 to which the back side decorative sheet 21 is attached is turned upside down again so that the front surface 11a faces upward, and the concave portion of the back surface 11c passes from the rear end of the front surface 11a through the front end surface 11b. The front surface side decorative sheet 21 is attached to the region reaching the groove 20, and the tip portion 21a thereof is folded into the concave groove 20 (FIG. (D)). Alternatively, the tip portion 21a may simply be projected into the opening of the concave groove 20. Since the surface material 17 is made of a wood fiber material such as MDF having a smooth surface, the surface side decorative sheet 21 can be attached without peeling off.

In this way, the shelf board main body 11 to which the front surface side decorative sheet 21 and the back surface side decorative sheet 22 are attached is turned upside down again so that the back surface 11c faces upward, and the adhesive is applied into the groove 20. By fitting the joint material 23 later, the tip portions 21a and 22a of the decorative sheets 21 and 22 are folded into the concave groove 20 to manufacture the shelf board 10 shown in FIGS. 1 and 2. At the stage where the decorative sheets 21 and 22 are attached ((c) and (d) in the figure), these tip portions 21a and 22a are in a state of merely protruding toward the opening of the concave groove 20. Further, by fitting the joint material 23 into the concave groove 20, the decorative sheet tip portions 21a and 22a are pressed against the groove walls on both sides of the concave groove 20 (see FIG. 2), so that the decorative sheet tip portions 21a and 22a are pressed. It is firmly held in the groove 20 and does not peel off or loosen.

The length L1 of the front surface side decorative sheet 21 used in this embodiment is La for the depth dimension of the shelf board main body 11 (length of the front surface plate 17 / back plate 18), Lb for the thickness dimension of the shelf board main body 11, and the shelf. When the distance from the front end surface 11b of the plate body 11 to the concave groove 20 is Lc, and the length of the tip portion 21a folded into the concave groove 20 (or projecting into the opening of the concave groove 20) is α, L1 = It is La + Lb + Lc + α, and the length L2 of the back surface side decorative sheet 22 is the distance from the rear end of the shelf board main body 11 (the rear end of the front surface plate 17 / back surface plate 18, the end abutted against the wall surface) to the concave groove 20. L2 = Ld + β, where β is the length of the tip portion 22a folded into the recessed groove 20. Since the concave groove 20 is formed at the position where the single plate laminated body 13 exists, the distance Lc from the front end surface 11b of the shelf board main body 11 to the concave groove 20 is the front end of the shelf plate main body 11. Although it depends on the thickness of the material 14, it is 20 mm in this embodiment, and the length α of the tip portion 21a folded into the concave groove 20 is sufficient to be about several mm, so that one decorative sheet is sufficient. Compared to the length (La × 2 + Lb) required for covering from the front surface of the shelf board body to the back surface through the front end surface, the length is almost half. Further, the back surface side decorative sheet 22 is always shorter than the front surface side decorative sheet 21 (L2 <L1). Therefore, even when the depth dimension La and the thickness Lb of the shelf board main body 11 are large, it is possible to apply makeup with a good appearance using a commercially available decorative sheet. Further, since the tip portions 21a and 22a of the decorative sheets 21 and 22 are firmly held by the joint material 23 in a state of being folded into the concave groove 20, the joint portions between the decorative sheets 21 and 22 are not exposed. Moreover, it is possible to maintain a stable decorative sheet attachment state for a long period of time without causing peeling or slack.

A shelf board according to another embodiment of the present invention (Example 2) is shown in FIG. Unlike the shelf board main body 11 according to the first embodiment, the shelf board main body 11A of the shelf board 10A does not have a honeycomb structure, mainly consists of a single plate laminated body 13, and is adjacent to the front of the single plate laminated body 13. It has a structure in which 14 is provided, and a concave groove 20 is formed in a range in which the single plate laminated body 13 exists. Since other configurations, operations, manufacturing methods, etc. are the same as those in the first embodiment, description thereof will be omitted.

In this embodiment, since the single plate laminate 13 occupies most of the shelf board main body 11, the formation position of the concave groove 20 is not particularly limited as long as it is within that range, but the concave groove 20 is compared with the shelf board main body 11A. By forming it in front of the target, the length L1 of the front surface side decorative sheet 21 can be shortened, which is a preferable embodiment. However, it is also possible to form the groove 20 further rearward as long as it is permissible in relation to the width dimension of the decorative sheet used.

Although the present invention has been described in detail with reference to examples, the present invention can be variously modified or modified within the scope of the invention defined in the claims.
