However, in the above-mentioned frame door, when the lattice body is not sandwiched between the glass plates and only the lattice body is incorporated into the frame body, in the conventional joint structure in which the outer frame material of the lattice body is simply inserted into the mounting groove, the crosspiece of the lattice body is used. When an external force acts on the frame material, the crosspiece may rotate with respect to the frame material and the lattice body may be distorted.

The present invention has been made in view of this point, and an object of the present invention is to prevent the lattice body from being distorted when an external force is applied to the frame structure in which the lattice body is incorporated.

In order to achieve the above object, in the present invention, not only the frame material of the lattice body but also the ends of a plurality of crosspieces are fitted into the fitting grooves of the pair of frame members facing each other of the frame assembly. ..

Specifically, in the first invention, a pair of frame members extending in parallel and the pair of frame members are bridged in a frame body in which four frame members are joined in a rectangular shape, and the respective frame members are bridged. It is a frame assembly incorporating a lattice body having a plurality of cross-sections having a rectangular cross section extending perpendicularly to the frame, and the inner end faces of the pair of frame members facing each other of the frame body are among the pair of frame members. A fitting groove having a rectangular cross section into which the corresponding frame material is fitted is formed, and in each of the fitting grooves, the corresponding frame material and the plurality of crosspieces fixed to the frame material in the longitudinal direction are formed. It is characterized in that the end is fitted.

In the first invention, the longitudinal ends of the plurality of crosspieces of the lattice body are fitted into the fitting grooves of the pair of stile members facing each other together with the frame member. Each fitting groove is formed in a rectangular cross section into which the frame material is fitted. In this way, by fitting the end portion of the cross section having a rectangular cross section into the fitting groove having a rectangular cross section, the end portion of the cross section is sandwiched by the side wall of the fitting groove of the stile member. Therefore, according to the above-mentioned frame assembly, even if an external force acts on the crosspiece, the crosspiece does not rotate with respect to the frame material, and the lattice body is not likely to be distorted. Therefore, according to the first invention, in the frame structure in which the lattice body is incorporated, it is possible to suppress the lattice body from being distorted when an external force is applied.

Further, according to the first invention, the joint portion between the frame material of the lattice body and the crosspiece is arranged in the fitting groove. Therefore, even if there is a gap between the frame material and the crosspiece, the gap can be hidden. Therefore, the design of the frame assembly can be improved.

In the second invention, in the first invention, at least the front surface and the rear surface of the frame member are covered with a thin plate-shaped or sheet-shaped decorative material, and the side surfaces of the fitting grooves are covered with the decorative material. It is characterized by being present.

In the second invention, the side surface of each fitting groove is covered with the same decorative material as the decorative material covering the front surface and the rear surface of the stile member. As described above, in the configuration in which not only the frame material but also the end portion of the crosspiece is fitted into the fitting groove of the frame member, the side surface of the fitting groove is exposed at the place where the crosspiece is not arranged in the fitting groove. Therefore, as described above, by covering the side surface of each fitting groove with the decorative material, the background of the core material of the stile member is not exposed. Therefore, the design of the frame assembly can be improved.

In the third invention, in the second invention, each of the stile members has a core material, a thin plate-shaped base material, and the decorative material attached to one surface of the base material, and the decorative material. In the pair of stile members having a surface material covering at least the front surface and the rear surface of the core material so as to be exposed and having the fitting groove formed therein, the two surfaces covering the front surface and the rear surface of the core material, respectively. Each of the materials has a folded portion that is folded back so that the decorative material is exposed inside the inner end surface of the core material, and the fitting groove is the pair of stile members in which the fitting groove is formed. In the above, the two folded portions and the core material form a section between the two folded portions.

In the third invention, each stile member includes a core material and a surface material covering at least the front surface and the rear surface of the core material, and the front surface and the rear surface are covered with a decorative material of the surface material. Further, in the above-mentioned frame assembly, two surface materials covering the front surface and the rear surface of the core material of the pair of frame members in which the fitting grooves are formed are extended to the inside of the inner end surface of the core material to form the core material. By folding back so that the decorative material is exposed inside the inner end surface, a folded-back portion that serves as a groove side wall of the fitting groove is formed. That is, a fitting groove is formed by the two folded portions obtained by folding the inner ends of the two surface materials and the core material. Further, by forming each folded portion by folding the inner end portion of each surface material so that the decorative material is exposed, the groove side surface of the fitting groove formed as a partition between the two folded portions is decorative. It will be covered with lumber. With such a configuration, a fitting groove in which the side surface of the groove is covered with the decorative material can be easily formed as compared with the case where the core material is cut out to form the fitting groove and the decorative material is attached to the side surface of the groove. Can be done.

In the fourth invention, in the third invention, each of the frame materials includes a frame core material made of square lumber, a thin plate-shaped base material, and the decorative material attached to one surface of the base material. However, it is characterized in that it is provided with an inner end surface of the frame core material and a frame surface material that integrally covers the front surface and the rear surface adjacent to the inner end surface so that the decorative material is exposed. ..

In the fourth invention, the frame material is a frame core material made of square lumber, the front surface, the inner end surface and the rear surface of the frame core material, and the base material and the decorative material as well as the surface material of each frame member. It is configured to be integrally covered with the surface material for the frame. With such a configuration, the portion of the inner end surface of each frame material where the crosspiece is not arranged is exposed in the fitting groove, but with the above configuration, the inner end surface of each frame material is rearward from the front end corner portion by the decorative material. Since it is covered seamlessly over the corners, the background of the frame core material is not exposed. Therefore, the design of the frame assembly can be improved by a simple configuration.

A fifth aspect of the present invention is, in any one of the first to fourth inventions, the lattice body is sandwiched between any two of the plurality of crosspieces adjacent to each other. It is characterized by having a plurality of pieces fixed to the crosspiece.

In the fifth invention, the lattice body is composed of a pair of frame members, a plurality of crosspieces, and a plurality of pieces. In such a grid body, as compared with a grid body having a plurality of vertical rails and a plurality of horizontal rails that are crossed and joined, the crosspieces are only joined to the frame member and the piece, so that an external force acts on the crosspieces. At that time, the crosspiece is easily rotated and the lattice body is easily distorted. However, according to the fifth invention, the rotation of the crosspiece can be suppressed by the above-mentioned configuration in which the end portion in the longitudinal direction of the crosspiece is fitted into the fitting groove, so that the lattice body can be suppressed from being distorted. ..

The sixth invention is characterized in that, in any one of the first to fifth inventions, the fitting groove is formed in a pair of stile members facing each other in the vertical direction of the frame body. be.

In the sixth invention, the crosspiece extends in the vertical direction, the crosspiece becomes longer than the structure extending in the left-right direction, and the strain of the lattice body due to the rotation of the crosspiece becomes large. However, according to the sixth invention, the rotation of the crosspiece can be suppressed by the above-mentioned configuration in which the end portion in the longitudinal direction of the crosspiece is fitted into the fitting groove, so that the lattice body can be suppressed from being greatly distorted. can.
