Description

  The present invention relates to a flash structure used for a door body such as a door of a building, a sliding door, a fence door, a partition, a furniture board, a table top board, and the like.

  Flush structures that are made by attaching face materials to the front and back of a frame made of birch and crosspieces are well known, doors such as building doors, sliding doors, coffin doors, partitions, furniture plates, table tops Widely used in An example of the framework of this flash structure is shown in FIG. 7, and is divided into three equal parts in the vertical (height) direction in a four-round frame made up of left and right vertical rods A1, A2 and upper and lower rods B1, B2. Two horizontal bars C1 and C2 are arranged, and lattice-shaped core members D1 to D3 each including two vertical members and one horizontal member are arranged in three sections divided by the horizontal bars C1 and C2. The frame E is arranged.

  In the flash structure, the face materials on the front and back sides are joined to the frame frames and crosspieces in a small area, and if the space of the frame is too large, the face material will be used when the face material is pushed in the space position. It becomes easy to produce a dent and a crack and becomes inferior in intensity | strength. For example, in FIG. 7, only two horizontal beams C1 and C2 that are equally divided into three in the vertical (height) direction are arranged in a four-sided fence made of left and right vertical fences A1 and A2 and vertical fences B1 and B2. When the frame is made, the area of each section divided by these horizontal rails C1, C2 is large, and when the face material is pushed near the center of this section, the face material is likely to be dented or cracked, In addition, since the adhesive strength of the face material becomes insufficient, a lattice-shaped core material D1 to D3 is arranged in the section to give the frame the required strength as the framework E.

  However, since the core members D1 to D3 are formed by assembling two vertical members and one cross member in a lattice shape, strict dimensional accuracy is provided for the section divided by the cross rails C1 and C2. Required. Moreover, when the dimensions of the doors and the sizes of the compartments are different, the grid-like core material D having dimensions corresponding to them must be prepared, which is not versatile and results in an increase in cost.

  Therefore, the problem to be solved by the present invention is large in dimensional tolerance, versatile enough to be used for doors and compartments of different dimensions if a core material of a predetermined dimension (length) is prepared. To provide a flash structure having a novel structure excellent in strength.

In order to solve the above-mentioned problems, the present invention according to claim 1 forms a framework by arbitrarily partitioning the inside of a four-sided fence made of left and right vertical fences and upper and lower vertical fences with vertical and / or horizontal crosspieces, In the flash structure formed by attaching face materials to the front and back of this frame, in the rectangular section in plan view partitioned between the frame material and the crosspieces or between the crosspieces, the frame thickness is substantially the same. A long strip-shaped core material having a width dimension is fixed at both ends at the diagonal position of the section, passes through the intersection of the two diagonal lines of the section, and divides the area of the section into approximately two equal parts. characterized in that it is arranged in a curved shape.

  According to a second aspect of the present invention, in the flash structure according to the first aspect, the core member has a length dimension larger than a diagonal length of the rectangular section in plan view, and the rectangular section in each plan view section has a length dimension. It is fixed at a substantially diagonal position.

  According to a third aspect of the present invention, in the flash structure according to the first or second aspect, the core material is arranged line-symmetrically in the rectangular section in plan view adjacent vertically and / or laterally. Features.

  According to a fourth aspect of the present invention, in the flash structure according to the first or second aspect, the two core members are arranged in each rectangular section in a plan view in a crossed state.

  According to the first aspect of the present invention, in the frame of the flash structure, the width dimension is substantially the same as the frame thickness in the rectangular section in plan view partitioned between the frame material and the frame material or between the frame materials. A long strip-shaped core material having a rectangular shape is fixed at a diagonal position that bisects the area of the section, and is arranged in a curved shape so as to pass through the intersection of the two diagonal lines of the section. Therefore, as in the prior art (FIG. 7), the area where the core material arranged in the compartment comes into contact with the face material is increased, and when the face material is pressed, the occurrence of dents and cracks is suppressed. , Increase the adhesive strength of the face material. In addition, since the core material is arranged in a curved shape, the dimensional tolerance is large, and if a core material having a predetermined size (length) is prepared, it can be used for doors and compartments having different dimensions. . In addition, the flash structure is manufactured by attaching the front and back materials after assembling the frame, but both ends of the core are fixed, so when transporting the assembled frame to the front and back material attaching process In addition, the core material does not fall off and is easy to handle.

  According to the invention according to claim 2, in the flash structure according to claim 1, since the core material longer than the diagonal line of the rectangular section in plan view is fixed at a substantially diagonal position of each rectangular section in plan view, The adhesion area to the face material is further increased, and the effect of suppressing the formation of a dent or crack when the face material is pressed is further increased.

  According to a third aspect of the invention, in the flash structure according to the first or second aspect, the curved core members arranged symmetrically in a rectangular section in plan view adjacent to the top and bottom and / or the left and right are to return to a straight line. Since the stress to be canceled out between the upper, lower, left and right rectangular sections, the deformation of the frame can be effectively prevented.

  According to the invention according to claim 4, in the flash structure according to claim 1 or 2, the two curved core members are arranged in each rectangular section in a plan view in a crossed state. Due to the stress that the curved core member returns to a straight line, an effect of holding each section in a rectangular shape is obtained, and the deformation of the frame is more effectively prevented.
