Polyurethane. polystyrene. Vinyl chloride resin. Vinyl acetate resin. It can be obtained by using a resin foam such as polyester and cutting it into a predetermined shape. As this foam, it is preferable to use a plate-shaped one. Further, it is preferable that a thin plate made of vinyl chloride resin or acrylic resin having a predetermined thickness is attached to the upper surface and the lower surface of the decorative portion. The thin plate can reinforce the decorative portion (for example, prevent expansion and contraction) and improve its aesthetic appearance.

The slits formed on the side peripheral surface of the decorative portion along the side peripheral surface in the second step have a certain depth on the side peripheral surface by using, for example, a cutter knife or other cutting tools. It is obtained by cutting in a straight line with. It is not necessary to form the groove. The cut depth of the slit can be variously set according to the length of the locking portion of the decorative tape.

The decorative tape used in the third step is made of a resin material such as vinyl chloride resin or acrylic resin, and has a constant cross section provided with the main body portion, the head portion and the locking portion. It has the flexibility of being extruded into a tape shape. The main body is in the shape of a strip, and one side surface of both side surfaces abuts and covers the side peripheral surface of the decorative portion, and the other side surface opposite the one side surface is exposed to the outside to decorate the decorative portion. To form a design surface. As one side surface of the main body portion, for example, one having an adhesive layer that abuts and joins the side peripheral surface when the side peripheral surface of the decorative portion is covered can be used.

Further, the main body portion is set in advance in the width direction (thickness direction of the decorative portion) to a value suitable for the thickest decorative portion among several kinds of decorative portions having different thicknesses. The length can be adjusted to be short so as to have a shape suitable for other decorated portions having a small thickness. For example, the main body part has one side surface that covers the side peripheral surface of the decorative part and has a notch that can be separated by a predetermined length in the width direction. It can be used by forming a strip and separating it by a predetermined length in the width direction corresponding to several kinds of decorative portions having different thicknesses. The thickness of the main body can be variously set according to the purpose.

The head is formed integrally with the upper end of the main body and is wider than the thickness of the main body. When the decorative tape is attached to the decorative section, the head is attached to the decorative section. A protruding edge is formed by protruding in the upper surface direction. This decorative edge makes it possible to obtain a decorative body having a good appearance on the upper surface and having an improved design effect. The cross-sectional shape of the head may be a substantially circular shape, a semicircular shape, a substantially elliptical shape, a substantially quadrangular shape, a substantially rectangular shape, a substantially triangular shape, or the like. The size of the head can be variously set as needed.

The locking portion is integrally formed on one side surface of the main body portion, protrudes substantially vertically from the one side surface of the main body portion, and extends along the longitudinal direction of the one side surface. The locking portion is pushed into a slit formed along the side peripheral surface of the decorative body, and is clamped by the reaction from the decorative portion body when pushed, whereby the entire decorative tape is formed. Is held in a fixed position in the decorative portion. The length, thickness and cross-sectional shape of the locking portion can be variously set according to the purpose. The cross-sectional shape of the locking portion can be, for example, a tapered triangle. Further, as the locking portion, for example, one having a projection portion having a shape capable of obtaining an anchoring effect when pushed into the slit of the decoration portion at the tip of the tapered triangle can be used.

In the third step, by pushing the locking portion of the decorative tape into the slit of the decorative portion, the slit is opened and the locking portion is further pushed, and the reaction thereof causes the locking portion to move in the thickness direction. Tightened, the decorative tape is securely fixed and held.

The process, the second process, and the third process are sequentially performed. Then, in the first step, a decorative portion having a predetermined thickness and having shapes such as characters, symbols and figures is obtained.

In the second step, a slit is formed along the side peripheral surface of the decorative portion obtained in the first step. In the third step, a decorative tape is prepared in advance. This decorative tape is a strip-shaped main body that covers the side peripheral surface of the decorative portion,
A head that is integrally formed on the upper end of the main body and protrudes toward the upper surface of the decorative portion and is wider than the main body, and is integrally formed on one side surface of the main body along the side peripheral surface of the decorative portion. It is a tape shape having a constant cross section, which includes a locking portion that is pressed by the formed slit.

And, the decorative tape has its locking portion,
It is pushed into the slit of the decorative portion and is wound and joined along the side peripheral surface of the decorative portion. That is, in the decorative tape, when the entire locking portion is pushed into the slit by the pushing operation, one side surface of the main body portion abuts and covers the side peripheral surface of the decorative portion. Then, both sides of the locking portion that has completed the pushing operation are clamped by the reaction of the decorative portion when pushing into the slit.

Since the decorative portion is made of resin foam, the locking portion is pushed into the slit,
The wall surface portion of the decoration portion forming the slit is compressed and absorbs the volume of the pushed-in engagement portion. For this reason, it is not necessary to form a groove having a width like a groove for a mortise, and a mere slit is sufficient.
Further, the locking portion is tightened by the compressed reaction force, so that the locking portion is firmly held.

As described above, in the third step, the decorative tape is securely wound around the side peripheral surface of the decorative portion by merely pushing the locking portion of the decorative tape into the slit of the decorative portion. Since they can be joined and can be mounted, the mounting work becomes easier. Further, when the decorative tape is attached to the decorative portion and the decorative body is formed by the third step, the head is wider than the thickness of the main body and the upper surface of the decorative portion is higher than the upper end of the main body. Protruding in the direction to form a decorative edge portion. The decorative edge portion is provided with an accent on the decorative portion, has a good appearance on the upper surface, and can be finished as a decorative body having an enhanced design effect.
On the other hand, in the main body portion of the decorative tape, one side surface thereof covers the side peripheral surface of the decorative portion in a band shape, and the other side surface opposite to the one side surface is exposed as a design surface to the outside, and the side peripheral portion. It has a good appearance and can be finished as a decorative body with an enhanced design effect.

Further, since the decorative tape is in the shape of a tape having a constant cross section, the above-described effects can be obtained even if the decorative tape is used by cutting out the required length at any portion in the longitudinal direction. The decorative body obtained by completing each of the steps by the method for manufacturing a decorative body of the present invention is, for example, a signboard, a wall surface of a building, a display tower, or a three-dimensional display by being attached to another mounting surface. And is useful for advertising, promotion, indicators, etc. Also, the decoration table
The colors are even more vivid and the range of correspondence is expanded by arranging many colors.
