Description

  The present invention relates to a support member suitable for storing service parts and consumable parts used in an image forming apparatus such as a copying machine and a printer, or an article such as an electronic device in a buffered state.

  Conventionally, in packing various parts used in an image forming apparatus, a foamed polystyrene block or the like is packed in a packing box for buffer support. However, polystyrene foam has problems such as the generation of harmful gases during incineration, and is not preferred for use from the standpoint of environmental protection. Therefore, even if the polystyrene foam is not used or the amount used is minimized, the article is well buffered. There is a high demand for possible packaging methods.

  For this reason, various structures for obtaining a buffering effect by using corrugated cardboard as a packaging material have been proposed. Examples thereof are shown in the following patent documents.

Further, the packaging box disclosed in the following Patent Document 1 also includes a corrugated cardboard box and a partition member for separating the stored article, and the partition member is a bent piece that can be bent elastically with respect to the stored article. The folded piece is folded and arranged in the gap between the box and the stored article. In addition, in order to securely and stably hold the stored article, the partition member reliably surrounds the periphery of the article according to the height of the article to be stored, and is cut out at the upper end to maintain the strength. Etc. are not formed.

  However, the partition member used in the conventional packaging box has been focused on how to ensure the strength of the partition member itself by preventing deformation as much as possible in order to protect the article from impact.

  Therefore, in the balance with the articles to be stored, there is a problem that the strength of the partition member is too strong, the impact at the time of dropping is directly applied to the stored articles, and the stored articles are damaged.

  An object of this invention is to provide the supporting member which can relieve | moderate the impact added to a stored article in view of such a subject of the member used for the said conventional packaging box.

In order to solve the above problems, the first aspect of the present invention is a support member that is housed inside a box body and supports an article,
The support member is
A support member main body having a bottom plate and a pair of wall members rising from both sides of the bottom plate;
A pair of side walls which are attached to both ends of the support member main body using notches;
A top plate that covers the top of the article placed on the bottom plate,
At least one of the pair of wall members and the pair of side walls surrounding the article is formed with a cutout recess cut out toward the top plate ,
The both edges of the top plate are formed with a plurality of cuts into which both edge portions rising toward the top plate of the notch recess are fitted, and the depth of the cut is the same. It is a member.

  Further, according to a second aspect of the present invention, the notch recess is formed so as to face each of the pair of wall members, and the position or width of the notch recess in each of the wall members is different. The support member according to the first aspect of the present invention.

  The present invention has an effect that it is possible to provide a support member that can further reduce the impact applied to the stored article.

  Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 shows a structure of a support member according to the present invention and an article packaging box 1 (hereinafter sometimes abbreviated as “packing box”).

  As shown in the figure, the packaging box 1 includes a box body 2 and a support member 3. The box body 2 is a cardboard box that is normally used, and the support member 3 is assembled by bending a plurality of elastic cardboard paper pieces.

  2 to 5 show development views of the corrugated paper pieces constituting the support member 3, and FIG. 2 shows the main body 5 of the support member 3. The main body 5 is integrally formed at both end portions of the bottom plate 6 so that wall portions 7 and 8 serving as side walls in the vertical direction can be folded (valley folded in the figure). Further, a horizontally extending extension 9 is integrally formed on the left side of the bottom plate 6, and an outer edge portion 10 is integrally formed in a T shape at an end thereof. Both end portions of the outer edge portion 10 are connected to the wall portions 7 and 8, and are folded up and raised up like the wall portions 7 and 8.

  An extension portion 11 extending horizontally is integrally formed on the right side of the bottom plate 6 of the main body 5, and the end portion of the extension portion 11 is a free end portion separated from other portions. Further, a window-like hole 13 is formed in the connecting portion of the bottom plate 6 with the wall portion 7, and the hole 13 is for adjusting the strength of the bottom plate 6 and obtaining a buffering effect.

  Furthermore, the wall portion 7 is formed with a square-shaped notch recess 15 (hereinafter also referred to as a notch recess that opens upward) with the notch opening facing upward when standing, and the other wall portion. 8 is formed with a similar recess 16 that is slightly smaller than the notch recess 15. Therefore, the interval A between the two edge portions 15 a and 15 b of the notch recess 15 is larger than the interval B between the both edge portions 16 a and 16 b of the other notch recess 16. These recesses 15 and 16 are intended to increase the elastic deformation capacity by adjusting the strength of the wall portion in consideration of the impact applied to the stored articles. When pressed against the wall portions 7 and 8 by impact, the wall portion is elastically deformed, so that a moderate buffering effect (improvement of buffering capacity) is obtained that the impact is not easily transmitted to the stored article. In addition, the recessed parts 25 and 31 (refer FIG.3, 4) which are opened upwards mentioned later are also the notch parts for adjustment for improving buffer capacity.

  On one end of the wall portions 7 and 8, cuts 7a and 8a that open upward are formed. Further, notches 7b and 8b are formed at the other ends of the wall portions 7 and 8 so as to open downward when standing. These cuts are used for fitting and fixing other paper pieces when the support member 3 is assembled. Further, leg portions 7c, 7c, 8c, and 8c are integrally formed on the lower portions of the wall portions 7 and 8 when they stand. The main body 5 of the support member 3 is formed of a single piece of corrugated paper.

  FIG. 3 shows a corrugated paper piece forming the left side wall 20 of the support member 3 shown in FIG. 1, and a bent piece 21 protruding upward is integrally formed on the side wall 20. Further, notches 22 and 23 that open upward are formed in the vicinity of both ends of the side wall 20. A concave portion 25 is formed in a portion of the side wall 20 that is biased to one side from the center in the width direction. A small concave portion 26 in a right angle direction is formed in the middle portion of the concave portion 25 and fits below the notch 23. The part opposite to the side where the bent piece 21, the recessed part 25 and the like are formed becomes the leg part 27.

  FIG. 4 shows a corrugated paper piece forming the right side wall 30, and a concave portion 31 that opens upward is formed in the central portion of the upper side portion of the side wall 30 when the side wall 30 stands up. A square recess 32 is formed at the center. The left and right side portions of the recess 32 are leg portions 33 and 34, and the leg portions 33 and 34 are formed with cuts 33a and 34a that open downward, respectively. The cuts 7a and 8a formed near the end portions of the wall members 7 and 8 are engaged with the cuts 33a and 34a, respectively.

  FIG. 5 shows a corrugated paper piece that becomes a top board 40 to be placed on the article. The corrugated paper piece is formed symmetrically in the front-rear and left-right directions, and trapezoidal concave portions 41 and 42 are formed on both sides of the central portion. ing. The enlarged diameter portions 43 and 44 are formed on both sides of the concave portions, and the enlarged diameter portions 43 and 44 are respectively formed with cuts 45 cut from the outside toward the center portion. These cuts 45 have the same depth L. Further, bent pieces 43c and 44c are integrally formed at the distal end portions of the enlarged diameter portions 43 and 44, respectively.

  FIG. 6 shows a state in which the support members 3 other than the top board 40 are assembled by combining these corrugated paper pieces. As can be seen from the figure, the support member 3 is simple to assemble because the corrugated paper pieces are joined and integrated by fitting the cuts formed in the corrugated paper pieces. can get. In addition, the notch recessed part provided in each paper piece is for improving the buffering effect by improving the elastic deformation capability of this corrugated paper piece by adjusting the size.

  Next, FIG. 7A shows a state in which the article P is placed on the support member 3. This article P is a substantially square article. The periphery of the article is surrounded in a state of being substantially in contact with the surfaces of the wall portions 7 and 8 and the side walls 20 and 30.

  FIG. 8 shows a state in which the top plate 40 is placed on the article P supported by the support member 3 as described above. As shown in FIG. 9, the top plate 40 has bent pieces 43c and 44c at both ends bent upward. The notch 45 on one side of the top plate 40 is fitted with both edges 16a and 16b of the notch recess 16 of the wall portion 8 on one side as fitting pieces, and the notch 45 on the other side is fitted into the notch 45 on the other side. The both edge portions 15a and 15b of the notch recess 15 of the wall portion 7 on the other side are fitted as fitting pieces, respectively.

  As described above, the packaging box 1 houses the support member 3 in the box body 2 and covers the top plate 40 with the article placed on the bottom plate 6 of the support member 3 so as to fix it. And packing is completed by filling packing materials, such as a polystyrene foam, as needed (it does not need to be filled), and closing the opening of the box main body 2. FIG. In this case, since the article P is surrounded and supported by the wall portions 7 and 8 of the support member and the side walls 20 and 30 on both sides, the article P is firmly held. Further, since the support member is made of elastic corrugated paper, the buffering effect is also excellent. Further, since the bent piece 21 of the support member and the bent pieces 43c and 44c of the top plate 40 are bent, they contact with the inner surface of the lid of the box body 2 along the inner wall of the box body, thereby also providing a cushioning effect. And the impact on the stored article can be reduced.

  Next, the reason why all the depths L of the cuts 45 of the top plate 40 of the present embodiment are set to be the same will be further described.

  As described above, the size and position of the notch recesses 15 and 16 provided in the support member main body 5 can be different from each other in order to adjust the buffering capacity. Therefore, the widths of the allowances A1, A2, B1, and B2 inside the wall portions 7 and 8 of the main body 5 for partitioning the storage space for the article P are all different (see FIG. 8).

  Therefore, unlike the above-described embodiment, the notch 45 of the top plate 40 can be formed in accordance with the allowances A1, A2, B1, and B2 having different widths.

  However, when using a top plate that has cuts with different depths that match the dimensions of each fitting in this way, it must be assembled in consideration of the orientation of the top plate during actual packaging work, so work efficiency Is troublesome and takes time.

  Therefore, according to the configuration of the support member of the present embodiment, it is possible to improve the buffering capacity of the article and easily assemble without considering the direction in which the top plate is inserted. Demonstrate.

  As described above, the support member according to the present invention supports the article placed on the bottom plate of the support member housed in the box body by surrounding it with the pair of wall members and the pair of side walls, and the top of the article. Since the plate is covered and protected, the article is surely supported. The top plate is formed with a plurality of cuts, and the top plate is fixed by fitting both edge portions of the notch recesses formed on the support member side to the plurality of cuts, so that the top plate is excellent in strength. . The notch recess is for improving the buffering capacity by increasing the elastic deformation capacity of the wall member due to the impact, and for effectively buffering and supporting the article. Since both edge portions of the recess are used as fitting pieces for cutting the top plate, there is no need to form separate fitting pieces and the structure is simple. Further, since the plurality of cuts on the top plate are all formed with sufficient depth and the same depth, the same top plate can be shared even when the size of the fitting piece changes, and assembly is also possible. Sometimes it can be fitted without worrying about the direction of the top plate, so there is no need to pay extra attention during the actual packing operation, and the packing operation can be performed efficiently and easily.

  In the said embodiment, it did not mention in particular about the relationship between the shape of the baseplate 6 and the shape of the bottom face of the articles | goods to accommodate. Then, next, the structure of the support member when the thin step D is formed on the side edge of the bottom surface of the article to be stored will be further described with reference to the drawings.

  FIG. 10 is a development view of the support member main body 5 ′ used in the support member of the present embodiment, and is a modification of the support member main body 5 shown in FIG. 2.

  In the developed view of FIG. 10, a folding paper piece S is left inside the notch recess 16.

  Here, the folding paper piece S is a paper piece for forming a cradle 50, which will be described later, and is separated from the wall member 8 by a cut 18 formed from both edges to a part of the bottom, and only the bottom is a wall. It is connected to the member 8. A broken line 18 in FIG. 10 is a crease, and if this piece of paper is bent on the bottom plate along the crease 18 at the bottom, a notch recess 16 is formed. Further, the paper piece S can be formed on the box-shaped cradle 50 by bending the paper piece S along the crease 18 into a U-shaped cross section. A portion indicated by 51 of the paper piece S is a protrusion, and a portion indicated by 52 is a warped portion. Further, the bottom portion of the cradle indicated by 53 is a remaining portion obtained by cutting out the protrusion 51, and is folded back in parallel with the bottom plate 6 and placed on the bottom plate 6.

  FIG. 11 is a perspective view of the support member 3 ′ provided with the cradle 50.

  As shown in the figure, a box-shaped cradle formed by bending the corrugated paper piece S into a U-shaped cross section at one edge of the bottom plate 6, that is, a portion adjacent to the notch recess of the wall member 8. 50 is provided in a state of being placed on the bottom plate 6. As shown in FIGS. 12 (b) and 12 (c), this cradle 50 is integrally provided with a protrusion 51 protruding downward, and this protrusion 51 is inserted into the slit 14 formed in the bottom plate 6. Has been. A warped portion 52 is formed in the vicinity of the tip portion of the protrusion 51. The warped portion 52 is slightly deformed and is forcedly inserted into the slit 14, but after insertion, the warped portion 52 is engaged with the back surface (lower surface) of the bottom plate 6. Therefore, the bottom plate 6 is supported in a state of being suspended by the protrusions 51. For this reason, the bottom plate is difficult to be deformed downward. Here, FIG.12 (b) is a figure which shows the state which mounted the article P for description in AA arrow sectional drawing (refer FIG. 11) of support member 3 'of this Embodiment. .

  Next, FIG. 12A is a perspective view showing the article P placed on the support member 3. This article P is a service part used in an image forming apparatus having a substantially square shape, and a triangular notch K is formed in the vicinity of one corner. Further, a thin step D is formed on one side edge of the article. This article P is placed on the bottom plate 6 with the step D formed downward, and the step D is a box-shaped receiver formed by folding the cardboard paper piece S into a U-shaped cross section. It is placed on the table 50.

  Therefore, if the structure is provided with the cradle 50, the article will not be inclined due to the impact at the time of dropping, so that the impact force is not concentrated on the boundary portion DL between the step portion D and the bottom plate. . Therefore, the bottom plate is deformed at the boundary portion DL, and it is possible to avoid the state where the original shape is not restored. The periphery of the article P is surrounded in a state of being substantially in contact with the surfaces of the wall portions 7 and 8 and the side walls 20 and 30.
