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 conservation. 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.

  What is disclosed in the following Patent Document 1 is for storing articles having protrusions in a plurality of storage portions that are partitioned by storing lattice-like partition portions in a packing box. The size of the storage portion The size is such that an article excluding the protrusion can be stored and an article including the protrusion cannot be stored, and an insertion hole through which the protrusion of the stored article is inserted is formed on the surface of the partition.

Moreover, what is disclosed in the following Patent Document 2 includes a 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. It is made of a corrugated cardboard material, and the folded piece is folded and arranged in the gap between the box and the stored article.
Japanese Patent Laid-Open No. 08-119255 JP 09-315423 A

  The packaging box described in Patent Document 1 is exclusively used for an article having a projection such as a transformer with a plug blade, and is not suitable for packaging an article having no projection. Moreover, since the packaging box of patent document 2 acquires a buffer effect with the elasticity of a bending piece, in the case of a big article, there exists a problem that the buffer effect cannot be anticipated so much. Further, no consideration is given to prevent an article having a stepped portion on the bottom face from being added to the bottom plate due to an uneven load.

  On the other hand, if the article to be packed has a stepped portion whose thickness changes, when placed on the bottom plate, one side (thin side) of the stepped portion does not come into contact with the bottom plate, so the supporting force is reduced and the stepped portion is reduced. Since the force applied to the bottom plate changes abruptly at the boundary portion of the portion, there is a problem that when the impact force is applied, the bottom plate is plastically deformed at this portion and the supporting force is reduced.

  Therefore, an object of the present invention is to provide a support member that can support an article having a stepped portion so that an excessive force is not applied to the bottom plate and can prevent deformation of the bottom plate due to stress concentration.

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 body having a bottom plate and a pair of wall members rising from both sides of the bottom plate;
A pair of side walls attached to both ends of the support member body using notches,
A notch recess that opens upward is formed in the middle of the wall member,
The both sides of the notch recess part piece are separated from the wall member by the cuts made at both edges of the notch recess part and bent onto the bottom plate, and the part piece is bent into a box shape by a plurality of folds, and the bottom plate It is a support member in which the receiving stand which receives the step part of an article | item is formed by mounting on top.

  In the second aspect of the present invention, the cradle is provided with a protrusion inserted into a slit formed in the bottom plate, and the protrusion has a warped portion that engages with the back surface of the bottom plate. It is a support member of the 1st present invention.

  According to the present invention, even an article having a stepped portion on the bottom surface can be supported so that excessive force does not act on the bottom plate, and deformation of the bottom plate can be prevented.

  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. In addition, a window-like hole 13 is formed in a connection portion between the bottom plate 6 and the wall portion 7, and a slit 14 is formed in a front portion of the other wall portion 8. The slit 14 is for fixing a cradle described later, and the hole 13 is for reducing the strength of the bottom plate 6 and obtaining a buffering effect.

  Further, the wall portion 7 is formed with a square-shaped notch recess 15 (hereinafter also referred to as a notch recess that simply opens upward) with the notch opening facing upward when standing up. A similar recess 16 is formed which 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. In the development view of FIG. 2, a folding paper piece S is left inside the notch recess 16. These notch recesses 15 and 16 are for adjusting the strength of the wall portion to increase the buffering capacity (elastic deformation ability). If this is provided, the internal article is impacted by the impact when dropped. When pressed against 7 and 8, the wall portion is elastically deformed, so that a moderate buffering effect (improvement of buffering capacity) is obtained that the shock 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.

  An example of the “partial piece” of the present invention corresponds to the folding paper piece S of the present embodiment.

  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 notch 18 formed from both edge portions to a part of the bottom portion, and only the bottom portion is a wall member. 8 is connected. A broken line 18 in the figure is a crease, and when this piece of paper is folded on the bottom plate along the fold 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.

  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 notches are used for fitting and fixing other paper pieces when the support member 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. Note that the main body 5 of the support member is formed of a single piece of corrugated paper.

  FIG. 3 shows a piece of corrugated paper that forms the left side wall 20, and a bent piece 21 that projects upward is integrally formed on the side wall 20. Further, notches 22 and 23 that open upward are formed near both ends of the side wall 20. A concave portion 25 that opens upward 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 that fits below the notch 23 is formed in an intermediate portion of the concave portion 25. The part opposite to the side where the bent piece 21, the recessed part 25, etc. 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 is a piece of corrugated cardboard serving as a top plate 40 to be placed on an article, and is formed symmetrically in the front-rear and right-and-left directions in the illustrated example, and has trapezoidal concave portions 41 and 42 formed on both sides of the central portion. Yes. 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 where the support members 3 other than the top board 40 are formed by combining these corrugated paper pieces. As can be seen from the figure, this support member 3 is a unitary cardboard paper piece that is joined and integrated by fitting the cuts formed in the cardboard paper piece, so that the assembly is simple and a strong bond strength is obtained. It is done. In addition, the notch recessed part provided in each paper piece is for improving the buffering effect by improving the elastic deformability of this corrugated paper piece by adjusting the size.

  As shown in FIG. 6, 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. 7 (b) and 7 (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.7 (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. . Moreover, FIG.7 (c) is a figure which shows the state which mounted the article P for description in the BB arrow sectional drawing (refer FIG. 11) of support member 3 'of this Embodiment.

  Next, FIG. 7A 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 receptacle formed by folding the corrugated paper piece S into a U-shaped cross section. It is placed on the table 50. For this reason, since the article does not tilt due to the impact at the time of dropping, the impact force is not concentrated on the boundary portion DL between the step portion D and the bottom plate. Therefore, it is possible to avoid a state in which the bottom plate is deformed at the boundary portion DL and does not return to the original shape. In addition, 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.

  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.

  The support member 3 is housed in the box body 2, and the top plate 40 is covered and fixed on the bottom plate 6 of the support member 3 with the article placed thereon. 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 3 and the side walls 20 and 30 on both sides, the article P is firmly held. Further, since the support member 3 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 slightly bent, they come into contact with the inner wall of the box body 2, so that the cushion effect is obtained, and the support member 3 is attached to the box. Supported in a buffered state in the body.

  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 above-described embodiment, the configuration including the top plate 40 in the support member has been described. However, the configuration is not limited thereto, and for example, a configuration not including the top plate may be used.

  Moreover, although the said embodiment demonstrated the case where the depth L of the notch 45 of the top plate 40 was made the same, it is not restricted to this, For example, the depth of notch may differ.

  In the above embodiment, the notch recess 16, which is an example of the “notch recess” of the present invention, also serves to adjust the strength of the wall portion, and the buffering capacity (elasticity of the support member 3 is adjusted by adjusting the strength. The case where the function for improving the deformation capability) is also used has been described. However, the present invention is not limited thereto. For example, the notch recess 16 formed after the folding paper piece S, which is an example of the “part of the notch recess” of the present invention, raises the above-described buffering capacity. It may be a configuration regardless of whether or not to do so.

  Moreover, in the said embodiment, the recessed part (15,16,31,25) which has a function for adjusting the intensity | strength of a wall part and improving an elastic deformation capability is respectively 4 side walls of the space which accommodates articles | goods. However, the present invention is not limited to this. For example, the concave portion having such a function may not be provided, and even if provided, the wall portions 7 and 8, the left side wall 20 and the right side are provided. You may form in any one of the side walls 30, and you may form in any one of several places.

  The support member according to the present invention is effective in the field of support members suitable for storing service parts and consumables used in image forming apparatuses such as copying machines and printers, or articles such as electronic devices in a buffered state. It is possible to provide a support member that can be used and can support an article having a stepped portion so that an excessive force is not applied to the bottom plate, and can prevent deformation of the bottom plate due to stress concentration.
