Description

Detailed description of the invention

[Technical field to which the invention belongs]
According to the present invention, a film-stretching hole in which a thermoplastic polyurethane film is coated by heat-sealing is provided on a single plate for a frame, and the double-sided frame is composed of an outer wall and an inner wall which are easily assembled and spaced. The present invention relates to a shock-absorbing support frame adapted for packing heavy goods and large-sized products, or easily damaged electronic equipment and precision equipment.

[Conventional technology]
Conventionally, as shown in FIG. 8, a cushioning support frame for packing a product formed by folding a cardboard material is provided with a film stretching hole 3 in a central portion, and the outer wall 1 is formed by bending the four surroundings around the hole. An inner wall 2 is formed inside the outer wall 1 at an interval, and the film extending hole 3 is covered with a thermoplastic resin film 4.

  At the corners of the overlapping frames, the overlapped corner connecting piece 16 cut out and provided at the end of the outer wall 1 is fitted into the fitting recess 8 provided at the end of the inner wall 1 to fit the outer wall. Were connected and fixed.

  With regard to the connection between the outer wall and the inner wall, which is a subject of the present invention, the outer wall 1 and the inner wall are formed by folding the inner wall connecting piece 15 provided by cutting the outer wall 1 and fitting into the fitting recess 8 provided by cutting the inner wall 2. The two were connected with a space between them.

  However, since the inner wall connecting piece 15 has a trapezoidal shape whose end on the inner wall side expands as shown in an enlarged view in FIG. 9, the inner wall 2 is prevented from moving in the distal end direction after being fitted into the fitting recess 8, 2 can be prevented, but as indicated by the arrow, it can move freely to the outer wall 1 side, so the set interval between the outer wall 1 and the inner wall 2 cannot be maintained, and it is difficult to maintain a predetermined frame strength. In particular, there is a problem in that there is a danger in supporting the packing of heavy or large objects, easily damaged electronic devices and precision devices.

[Problems to be solved by the invention]
The conventional cushioning support frame for packing has poor strength because the outer wall and inner wall, which are important for strength, are not fixed and maintained at a fixed interval, and there is a risk of damaging the package storage article. It is structurally unsuitable for use as a supporting frame for packing electronic equipment, precision equipment, and the like, which are easily damaged.

[Means for solving the problem]
In order to solve the conventional problem, the present invention is to fix the outer wall and the inner wall by firmly connecting the outer wall and the inner wall by fitting a grooved connecting piece provided on the outer wall into a fitting recess provided on the inner wall, In addition, the corners are moved by folding the bent corner supporting piece continuous to the outer wall toward the bottom side, and inserting the protruding insertion protruding piece into the fitting recess at the edge of the folded bottom surface continuous to the orthogonal outer wall. Above all, it has a structure in which the strength of the frame is remarkably improved by always keeping a constant interval, and the assembly and disassembly are simple.

  In the present invention, the film extension hole formed in the center of the square is bonded by heat fusion, covered with a thermoplastic polyurethane film, and the outer peripheral side of the film extension hole is bent to form four outer walls. In the cushioning support frame, a part of the outer wall is cut to provide a grooved connecting piece 5 having fitting cut grooves on both sides, and the outer edge of the film extending hole is bent to form four inner walls. Then, a part of the inner wall is cut, and the fitting cut groove is fitted into both ends of the inner wall at the cut portion, and a fitting concave portion is formed in which the grooved connecting piece is fitted.

  Also, at both ends of the outer wall portion, a folding corner portion support piece having an insertion protrusion is continuously provided, and the insertion protrusion is inserted into a bottom edge portion connected to the outer wall at a position orthogonal to the outer wall. Drill a bottom insertion hole.

A part of the outer wall 1 is cut, and a grooved connecting piece 5 having a fitting cut groove 6 is provided on both sides of a position spaced from the bent portion, and the outer edge of the film extending hole 3 is bent. The inner walls 2 and 2 ′ are bent so as to be parallel to the outer wall 1.

  A cut is made in a part of the inner wall 2 to form a bent fitting piece 7 to be bent. When the grooved connecting piece 5 is bent, the fitting cut groove 6 of the grooved connecting piece 5 is formed in the inner wall 2. A fitting recess 8 is formed so as to fit into both ends of the cut portion and to fit the grooved connecting piece 5.

By bending the grooved connecting piece 5 of the outer wall 1 inward, fitting it into the fitting recess 8 of the inner wall 2 and fitting the fitting cut groove 6 into the cut end of the inner wall 2, And the inner wall 2 are firmly connected and fixed.

  Also, at both end sides of the outer wall 1 portion, a folding corner portion support piece 9 having an insertion protruding piece 10 is continuously provided, and a bottom edge 11 continuously provided to an outer wall 1 ′ at a position orthogonal to the outer wall 1 is provided. A bottom insertion hole 12 into which the insertion protruding piece 10 is inserted is formed, and the corner of the frame is firmly fixed by inserting the insertion protruding piece 10 into the bottom insertion hole 12.
