Description

  The present invention relates to a laminated panel containing a reinforcing material.

  As a prior art document filed by the present applicant, there is a document disclosed for a resin panel in which a reinforcing material is accommodated in a foam as a core material (for example, Patent Document 1: Japanese Patent Laid-Open No. 2006-334801).

  In the resin panel of Patent Document 1, a housing part is formed in a foam as a core material, and a reinforcing material is fitted into the housing part to hold the reinforcing material. As a result, the positioning of the reinforcing material can be performed accurately, and the deformation due to the backlash prevention and molding shrinkage is prevented.

  In addition, there is a document that discloses a core material that contains a reinforcing material (for example, Patent Document 2: WO2009 / 136489).

  In the above-mentioned patent document 2, the end of the core material is press-fitted into the engaging groove of the reinforcing material to constitute one interior material in which the core material and the reinforcing material are integrated.

JP 2006-334801 A WO2009 / 136589

  Since the resin panel of the above-mentioned Patent Document 1 simply holds and holds the reinforcing material in the core material, the reinforcing material may come off the core material.

  On the other hand, since the interior material of the above-mentioned patent document 2 press-fits the end of the core material into the engagement groove of the reinforcing material, the reinforcing material is difficult to come off from the core material. However, in Patent Document 2, it is necessary to previously form an end surface shape corresponding to the reinforcing material on the core material, and after the end surface shape is formed on the core material, it is difficult to deform the end surface shape. .

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a laminated panel in which a reinforcing material is hardly detached from a core material even when an arbitrary reinforcing plate is accommodated in the core material.

  In order to achieve this object, the present invention has the following features.

Note that the storage forming portion 43 and the hinge forming portion 42 are preferably provided in the split mold 41 in the same direction as the parison P, as shown in FIG. Thereby, generation | occurrence | production of bent meat can be reduced. However, the storage forming portion 43 and the hinge forming portion 42 can also be provided in the split mold 41 in a direction orthogonal to the parison P.

  Next, as shown in FIG. 7, the split mold 41 is moved from the closed position to the open position, the two split molds 41 are opened, and the molded core material 5 is taken out between the split molds 41. . Thereby, the core material 5 having the storage part 10 and the hinge part 7a can be formed.

  Next, as shown in FIG. 4 (a), a notch 52 is formed at the end of the storage portion 10 in the longitudinal direction by manual operation to form a claw portion 51. In this case, the claw portion 51 is cut out in a flat state. And as shown in FIG.4 (b), the nail | claw part 51 is once stood up by manual operation.

  Next, the parison P is pressed against the cavity 62 of the split mold 61 by vacuum or compressed air, and then the core material 5 holding the reinforcing material 9 is brought into contact with the inner surface of the sheet-like parison P in one cavity 62B. The mold is clamped by placing the parisons P in the cavities 62 so that the welded part is formed on the entire circumference of the peripheral wall 4 of the laminated panel 1 by the pinch-off part of the split mold 61. The inner surface of the melted parison P and the outer surface of the core material 5 are welded to form the laminated panel 1 in which the core material 5 holding the reinforcing material 9 is embedded with the front wall 2 and the back wall 3. Thereby, the laminated panel 1 in which both surfaces of the core material 5 are covered with the resin sheet P can be obtained.

  The laminated panel 1 described above can also be molded by a mode in which a pair of preformed resin sheets is blow-molded.

  Moreover, in the said manufacturing method, it decided to shape | mold the core material 5 using the cylindrical parison P of a molten state. However, the resin for forming the core material 5 is not limited to the cylindrical parison P, and can be molded using a molten tubular or sheet-like parison P alone.

  Further, in the above manufacturing method, the front wall 2 and the back wall 3 were formed using a single layer parison P in a molten state. However, it is also possible to form the front wall 2 and the back wall 3 using a multi-layer parison P.

  Further, in the above manufacturing method, the notch 52 is formed on the longitudinal end portion of the storage portion 10 by manual operation to form the claw portion 51. However, it is also possible to form the claw portion 51 by making the cut 52 with the split mold 41. In this case, as shown in FIG. 9, the pinch-off portions of the respective divided dies 41 are brought into contact with each other to form parting lines around the core material 5 and formed on the core material 5 by the storage forming portion 43.

The core material 5 with the reinforcing material 9 locked thereon is formed. Next, the core material 5 in which the reinforcing member 9 is locked by the claw portion 51 and the resin sheet P are clamped by the split mold 61 to form the laminated panel 1. Thereby, even when an arbitrary reinforcing plate 9 is housed in the core material 5, it is possible to provide the laminated panel 1 in which the reinforcing material 9 is unlikely to be detached from the core material 5.

(Second Embodiment)
Next, a second embodiment will be described.

  In the first embodiment, as shown in FIG. 3 (b), the core member 5 is cut 52 to form a claw portion 51, and the reinforcing member 9 is locked by the claw portion 51.

  In the second embodiment, as shown in FIG. 10B, a part of the core material 5 is crushed to form a protruding portion 81, and the reinforcing member 9 is locked by the protruding portion 81. As a result, even when an arbitrary reinforcing plate 9 is accommodated in the core material 5, the laminated panel 1 in which the reinforcing material 9 is unlikely to be detached from the core material 5 can be provided as in the first embodiment. Hereinafter, the second embodiment will be described with reference to FIG.

As shown in FIG. 10 (a), the portion where the protrusion 81 is formed has a hollow portion 82, and after the reinforcing material 9 is fitted into the core material 5, as shown in FIG. 10 (a). By crushing the hollow portion 82 from above the hollow portion 82, as shown in FIG. 10 (b), a protruding portion 81 is formed, and the protruding portion 81 is inserted into the opening 91 of the reinforcing member 9, and the The reinforcing member 9 is locked by the protruding portion 81 inserted into the opening 91. In addition, since the core material 5 of the present embodiment crushes the hollow portion 82 to form the protruding portion 81, it is preferable to cut the side wall 80 constituting the hollow portion 82. Thereby, the hollow part 82 can be crushed and the protrusion part 81 can be formed easily. Further, since the hollow portion 82 is bent starting from the cut portion of the side wall 80 to form the protruding portion 81, the shape of the protruding portion 81 formed by crushing the hollow portion 82 can be a specific shape. In addition, the protrusion 81 can be easily inserted into the opening 91 of the reinforcing member 9. For example, in the case where the side wall 80 is not cut, it is difficult to specify the shape of the protrusion 81 because the hollow portion 82 is not bent from which part of the side wall 80, and the protrusion 81 is provided in the opening 91 of the reinforcing member 9. It becomes difficult to insert. On the other hand, when the side wall 80 is cut, the hollow portion 82 is bent starting from the cut portion, so that the shape of the protruding portion 81 can be easily specified, and the protruding portion 81 is formed in the opening 91 of the reinforcing member 9. Can be easily inserted. For this reason, it is preferable to make a cut in the side wall 80 constituting the hollow portion 82.

A laminated panel 1 in which both surfaces of the material 5 are covered with the resin sheet P can be obtained.

<Operation / Effect of Laminated Panel 1 of this Embodiment>
Thus, in the laminated panel 1 of this embodiment, a part of the core material 5 is crushed to form the protruding portion 81, and the reinforcing member 9 is locked by the protruding portion 81. As a result, even when an arbitrary reinforcing plate 9 is accommodated in the core material 5, the laminated panel 1 in which the reinforcing material 9 is unlikely to be detached from the core material 5 can be provided as in the first embodiment.

  In the above embodiment, as shown in FIG. 10A, the hollow portion 82 is crushed to form the protruding portion 81 shown in FIG. 10B. However, as shown in FIG. 11A, the solid portion 83 can be crushed to form the protruding portion 84 shown in FIG. Also in this case, the protruding portion 84 is inserted into the opening 91 of the reinforcing member 9, and the reinforcing member 9 is locked by the protruding portion 84 inserted into the opening 91. Also in the case of the configuration shown in FIG. 11, it is preferable to cut the side wall 85 of the solid portion 83. Thereby, the solid portion 83 is bent starting from the cut portion of the side wall 85, and the protruding portion 84 can be easily formed. Further, since the solid portion 83 is bent starting from the cut portion of the side wall 85 to form the protruding portion 84, the shape of the protruding portion 84 formed by crushing the solid portion 83 can be made a specific shape. In addition, the protrusion 84 can be easily inserted into the opening 91 of the reinforcing member 9. It is also possible to make a plurality of through holes in the side wall 85 instead of the notches so that the solid portion 83 is easily crushed. That is, as long as the solid portion 83 can be crushed and the protruding portion 84 can be easily formed, any treatment can be performed on the solid portion 83 in advance.

  However, as shown in FIG. 11, the solid portion 83 is crushed to form the protruding portion 84, as shown in FIG. 10, more than the hollow portion 82 is crushed to form the protruding portion 81. Power is needed. For this reason, as shown in FIG. 10, it is preferable to form the hollow part 82 and crush the hollow part 82 to form the protruding part 81.

(Third embodiment)

As shown in FIG. 12 (a), the portion where the opening 89 is formed has a hollow portion 86, and a cut 88 is provided at one end of the side wall 87 constituting the hollow portion 86, and the side wall 87 is opened. Thus, the opening 89 can be formed. Then, the end of the reinforcing material 9 is inserted into the opening 89, and the reinforcing material 9 is locked.

  In the laminated panel 1 of the present embodiment, the core material 5 in which the reinforcing material 9 is locked by the opening 89 is arranged as the core material 5 shown in FIG. A broken laminated panel 1 can be obtained.

  In the configuration of FIG. 12, the side wall 87 is cut at one end and the side wall 87 is left in the opening 89. As a result, when the end of the reinforcing material 9 is inserted into the opening 89, the side wall 87 exhibits a function of filling the gap between the reinforcing material 9 and the opening 89 and a function as a cushioning material. Can do. However, the side wall 87 can be removed by making cuts 88 at both ends of the side wall 87 without leaving the side wall 87 in the opening 89. In this case, since there is no side wall 87, the end of the reinforcing member 9 can be easily inserted into the opening 89.

<Operation / Effect of Laminated Panel 1 of this Embodiment>
As described above, in the laminated panel 1 of the present embodiment, a part of the core material 5 is opened to form the opening 89, the end of the reinforcing material 9 is inserted into the opening 89, and the opening 89 reinforces it. Lock the material 9. As a result, even when an arbitrary reinforcing plate 9 is accommodated in the core material 5, the laminated panel 1 in which the reinforcing material 9 is unlikely to be detached from the core material 5 can be provided as in the first embodiment.

  The above-described embodiment is a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiment alone, and various modifications are made without departing from the gist of the present invention. Implementation is possible.

  For example, in the above embodiment, the decorative member 6 is attached to the upper surface of the front wall 2 as the laminated panel 1. However, the decorative member 6 may be omitted, and the upper surface of the front wall 2 may be exposed as it is.

  In the above embodiment, the core material 5 has been described by taking a solid configuration as an example. However, the core material 5 can also be provided with a plurality of depressions in the core material 5 as shown in FIG. 4 of Patent Document 2 (WO2009 / 136489), for example. Further, as shown in FIG. 5 of Patent Document 2, it is possible to provide a through hole in the core material 5. That is, the configuration of the core material 5 is not limited to a solid configuration, and a part of the core material 5 can be made hollow or a part of the core material 5 can be made solid. A hollow part and a solid part can be appropriately provided in the core member 5 according to the shape and arrangement position of the hinge part 7a and the accommodating part 10. In addition, since the core material 5 of this embodiment forms the hinge part 7a and the accommodating part 10, it is preferable to provide holes, such as a hollow part, in the circumference | surroundings. Thereby, even if the hinge part 7a and the storage part 10 are formed using the parison P, it is possible to ensure a resin escape space in the formed part, and thus it is possible to prevent the occurrence of resin accumulation.
