The sheet wrapping product according to the prior art described in Patent Document 1 is assumed to be used as a flooring (paragraph 0024), but such a sheet wrapping product is used for a wide variety of building materials. For example, considering the case where it is used for a step board or a counter of a staircase, the corners of the front side surface and the lateral side surface that appear on the front surface in the construction state are easily noticeable by humans and are easily touched by human bodies and objects. Therefore, when a joint of a decorative sheet appears at the corner as in Patent Document 1, the decorative pattern of the decorative sheet is cut off at the joint, and the appearance of the decorative sheet is deteriorated. The sheet is easily peeled off.

In addition, the above-mentioned stair treads and counters improve the design and make the front side and side surfaces of the circuit board less susceptible to injury or damage when hit by a human body or object. The corners may be chamfered, but the conventional technology described in Patent Document 1 assumes use as a flooring material, so that a decorative sheet is wrapped on such a chamfered base material. There is no consideration for. When the joint of the decorative sheet is formed in the area of the chamfered portion, the disadvantages such as the above-described deterioration in appearance and peeling of the decorative sheet become more remarkable.

Therefore, the problem to be solved by the present invention is to provide a sheet wrapping product that has a good appearance and is difficult to peel off even after many years of use.

In order to solve this problem, the invention according to claim 1 of the present application includes a plate-like substrate having a shape in which at least one of the front side surface and the lateral side surface that appears on the front surface in the construction state is chamfered, A sheet wrapping product comprising at least one decorative sheet that is continuously pasted from the front side surface to the chamfered lateral side surface, the decorative sheet comprising at least a surface covering portion that covers the surface of the plate-like substrate; , over a portion formed to extend laterally from the portion and partial from the surface covering portion is extended and formed on the front covers the front side of the plate-shaped base material from the chamfered portion of the plate-shaped substrates of the lateral sides of the longitudinal the cover and the first side surface covering portions comprising a portion covering, the lateral sides are extended from the surface covering portion laterally not covered by the first side surface covering portion of the plate-shaped substrates of the remainder of the length direction Having two side covering parts, The first side surface covering portion and the chamfered in the longitudinal direction of the lateral sides of the second side distal ends of the covering portion is formed in agreement with the plate-shaped substrates thickness direction appears seam plate-shaped substrates of the粧sheet It is located behind the part.

The invention according to claim 2 of the present application is the sheet wrapping product according to claim 1, wherein the decorative sheet is further extended to the rear of the surface covering portion to cover the rear side surface of the plate-like substrate. And the seam between the second side surface covering portion and the third side surface covering portion of the decorative sheet appears along the corners of the lateral side surface and the rear side surface of the plate-like substrate.

Thus, a decorative sheet that can be suitably used for sticking a single decorative sheet over the lateral surface to obtain a sheet wrapping product can be provided.

It is a perspective view (a)-(c) which shows a sheet wrapping product by the present invention. It is a top view (a)-(c) which shows the shape of the decorative sheet used for each sheet wrapping product (a)-(c) shown in FIG. It is a top view (a)-(c) which shows arrangement | positioning and a cut part of a decorative sheet (only two continuous sheets are shown in figure) at the time of manufacturing the sheet wrapping product of FIG. 1 (a)-(c) continuously. .

FIG. 1 is a perspective view showing several embodiments of a sheet wrapping product according to the present invention. The sheet wrapping product 10 of FIG. 1A is provided with curved chamfered portions 12 and 12 at both ends of a front side surface. The sheet wrapping product 10 in FIG. 1 (b) has a beveled chamfered portion 13 at both ends of the front side surface. The sheet wrapping product 10 in FIG. 1 (c) is attached only to one end (left end) of the front side surface. The sheet wrapping product 10 in FIG. The surface and the four side surfaces of the base material on which the curved chamfered portion 12 is applied are adhered so as to be covered with a single decorative sheet 11. The joint 14 of the decorative sheet 11 is located behind the chamfered portions 12 and 13 of the base material on the lateral side surface of the sheet wrapping product 10.

In the sheet wrapping product 10 shown in FIGS. 1A to 1C, a decorative sheet 11 cut as shown in FIGS. 2A to 2C is used. That is, the decorative sheet 11 used in the sheet wrapping product 10 of FIG. 1 (a) has a surface covering portion 11a and a first side surface covering a part of the lateral side surface from the front side surface of the base material through the left and right chamfered portions 12, 12. It has the coating | coated part 11b, the 2nd side surface coating parts 11c and 11c which cover the remainder of a base material side surface, and the 3rd side surface coating part 11d which covers a base material back side surface. The surface covering portion 11a has substantially the same shape and the same dimensions as the substrate surface. The first side surface covering portion 11b has laterally extending portions 11e and 11e that protrude forward from the surface covering portion 11a with a width that is substantially the same as the base material side surface height (base material thickness) and that protrude to the left and right sides. . The length of each laterally extending portion 11e is set larger than the length along the curved surface of the chamfered portion 12. Each second side surface covering portion 11c protrudes from the surface covering portion 11a in the left-right direction with a width substantially the same as the base material side surface height (base material thickness), and its length is chamfered from the rear corner portion 15 of the base material. The length of the first side surface covering portion 11c is extended from the front side surface of the base material through the chamfered portion 12 to the lateral side surface and pasted to the side surface, and the second side surface covering portion 11c is disposed on the side of the base material. These tips are set to form a seam 14 when attached to the side. The third side surface covering portion 11d protrudes rearward from the surface covering portion 11a with a width that is substantially the same as the base material side surface height (base material thickness), but there are no protruding portions on the left and right sides. The surface covering portion 11a of the decorative sheet 11 is adhered to the substrate surface, and the first side surface covering portion 11b, the second side surface covering portions 11c and 11c, and the third side surface covering portion 11d are adhered to the four side surfaces of the substrate. By doing so, the sheet wrapping product 10 of FIG. 1A is obtained.

The same applies to the decorative sheet 11 (FIG. 2B) used in the sheet wrapping product 10 of FIG. The decorative sheet 11 (FIG. 2 (c)) used in the sheet wrapping product 10 of FIG. 2 (c) is substantially the same, but in this example, a curved chamfer is formed only at one end (right end) of the front side surface of the substrate. Since the portion 12 (or the beveled chamfered portion 13) is formed, the second side surface covering portion 11c has only a laterally extending portion 11d extending to the chamfering side, and the non-chamfered side 11f is a surface covering. It is on the extension of the left short side of the part 11a. Further, both ends of the second side surface covering portion 11c 'on the non-chamfered side are on an extension line of the long side of the surface covering portion 11a and are formed to have the same length as the short side.

The manufacturing process of the sheet wrapping product 10 shown in FIGS. 1A to 1C will be described with reference to FIGS. 3A to 3C. A plurality of plate-like substrates are sequentially conveyed at predetermined intervals. While transporting at a predetermined speed by the apparatus, the surface covering portion 11a of the long continuous decorative sheet sent out from the roller at a speed synchronized with the transport speed of the base material is adhered to the surface of the base material and disposed on both sides in the transport direction. The roller attaches the central portion of the first side surface covering portion 11b to the front surface of the base material and also attaches the third side surface covering portion 11d to the rear surface of the base material. Next, the decorative sheet is cut at a predetermined position between the plate-like substrates (indicated by an arrow 16 in FIGS. 3A to 3C), and unnecessary portions (in FIG. 3A to 3C are hatched portions). Is cut with a laser to obtain a decorative sheet 11 having the shape shown in FIGS. Thereafter, the base material having the decorative sheet 11 attached to the front surface, the front side surface, and the rear side surface is lowered from the conveying device, and the laterally extending portions 11e and 11e of the first side surface covering portion 11b of the decorative sheet 11 are chamfered on the substrate. The sheet wrapping product 10 shown in FIGS. 1 (a) to 1 (c) is manufactured by passing it through 12 and 12 and pasting it to a part of the left and right lateral sides by hand. Instead of manual work, the base material with the decorative sheet 11 attached to the front surface, front side surface and rear side surface is transferred to another transport device, and the decorative sheet for the left and right side surfaces of the substrate is provided with rollers arranged on both sides of the transport direction. A pasting operation may be performed. When it is necessary to attach a decorative sheet to the back surface of a tread board for an open staircase, a step of attaching another decorative sheet to the back surface of the substrate is added before or after the above step.

In the above description, the sheet wrapping product 10 in which the front surface and the four side surfaces (or the back surface) of the plate-like base material are coated with the decorative sheet 11 has been described, but the present invention is not limited to this. Further, a sheet wrapping product in which the surface of the plate-like substrate, the front side surface, and the left and right side surfaces are covered with the decorative sheet 11 from which the third side surface covering portion 11d is omitted may be used. If the third side surface covering portion 11d of the decorative sheet 11 is omitted, the decorative sheet is not attached to the rear side surface of the plate-like base material, and the base material is exposed, but the base rear side surface is pushed against a wall surface or the like. Since there is no need to apply makeup to the rear side surface of the base material for sheet wrapping products (stair treads, counters, etc.) applied in a contact state, such an embodiment is also within the scope of the present invention. According to this embodiment, since the area of the decorative sheet 11 can be reduced by the amount omitted from the third side surface covering portion 11d, the cost associated with the decorative sheet can be reduced while maintaining the appearance in the construction state.

Further, in the case where the chamfered portions 12 and 13 are provided only on one of the front corners of the front side surface of the base material (for example, FIG. 1C), not only the third side surface covering portion 11d is omitted, but also The decorative sheet 11 in which the laterally extending portion 11e on the non-chamfered side of the first side surface covering portion 11b and the second side surface covering portion 11c on the non-chamfered side are also omitted is the surface of the plate-like substrate, the front side surface, and the lateral surface on the chamfered side. It is good also as the sheet wrapping product which coat | covered the side surface. If the third side surface covering portion 11d of the decorative sheet 11 and the non-chamfered side laterally extending portion 11e of the first side surface covering portion 11b and the second side surface covering portion 11c on the non-chamfered side are omitted, the rear side surface and the non-side surface of the plate-shaped substrate are omitted. Sheet wrapping product (staircase) constructed with the decorative sheet not attached to the side surface of the chamfered side and the base material exposed, but with the rear side surface of the base material and the side surface abutted against the wall surface, etc. Such an embodiment is also within the scope of the present invention because it is not necessary to apply makeup to these surfaces of the base material in the case of a tread board or a counter). According to this embodiment, in addition to the cost reduction effect due to the small area of the decorative sheet as described above, unnecessary portions when cutting the decorative sheet (shaded portions in FIGS. 3A to 3C) ) Becomes smaller, the cost associated with the decorative sheet can be greatly reduced while maintaining a good appearance in the construction state.

In addition, although it is essential that the seam 14 between the laterally extending portion 11e of the first side surface covering portion 11b and the second side surface covering portion 11c of the decorative sheet 11 is located behind the chamfered portions 12 and 13, The position is not limited as long as it is satisfied, and the lengths of the laterally extending portion 11e and the second side surface covering portion 11c of the first side surface covering portion 11b are set according to the position of the joint 14. In any case, the former length is a dimension that completely covers the chamfered portions 12 and 13 but the end is located in front of the rear corner portion 15, and the latter length is from the rear corner portion 15 to the chamfered portion 12. , 13 is the dimension in which the front end is located, and the total of these lengths is obtained by adding the length of the side surface of the base material (the flat portion not chamfered) to the surface length of the chamfered portions 12, 13. Set to be equal to the dimension.

In the illustrated embodiment, the tip end position of the laterally extending portion 11e of the first side surface covering portion 11b is aligned with the outer long side of the second side surface covering portion 11c. 3 (a) to 3 (c) has a merit that can be minimized, but is not necessarily limited to this, and the laterally extending portion 11e of the first side surface covering portion 11b is chamfered. 12 and 13 can be set as appropriate in consideration of the work efficiency when adhering to the side surface of the substrate and the design effect by the joint position. For example, when the length of the laterally extending portion 11e of the first side surface covering portion 11b is made relatively large and the extension length of the second side surface covering portion is made relatively short, the joint of the decorative sheet becomes the rear side surface of the base material. The position is close to the corner, and it is located behind (back side) that is difficult to see and touch in the construction state, so that the appearance is maintained well and the effect of preventing the decorative sheet from peeling off is further improved. To do. It is also possible to consider that the seam 14 is formed at a position where the pattern of the decorative sheet appears to be continuous.
