Description

  The present invention relates to a cardboard box for a bicycle that is stored and transported in a folded state and is used for storing and transporting a bicycle in an assembled state. More particularly, the present invention relates to a bicycle cardboard box used for storing and transporting a bicycle, particularly a bicycle in a state of being disassembled into a wheel and a frame component which is a component other than the wheel.

  In recent years, road races such as Tour de France, bicycle races such as track races, mountain bike races, and BMX have become popular. The competition bicycles used in these competitions are boxed in a disassembled state, transported to the competition venue by means of courier, etc., and used for competitions. For this transportation, a bicycle packing box (also called “wheel-carrying box” or “wheel-carrying box”) for packing and transporting the bicycle in a state of being disassembled into wheels and parts other than the wheels is used. Has been.

  As such a bicycle packing box, for example, the inventor includes a box body whose upper surface is opened, a lid that covers the opening of the box body, and an insole for reinforcing the bottom of the box body. A cardboard bicycle transport box has been proposed (see Patent Documents 1 and 2).

  Since the box described in Patent Documents 1 and 2 does not have a flap as a lid around the opening of the box body like a normal cardboard box, the storage and removal of the bicycle may be hindered by the flap. Therefore, the storing and taking out operations can be performed very smoothly. Moreover, since the insole is provided at the bottom of the box body, a heavy bicycle can be stored without any problem. Furthermore, since it is made of cardboard, it is easy to fold and assemble, and can be stored in a folded state and assembled and used only when the bicycle is transported.

  A bicycle packaging box for transporting a bicycle in a state where it is disassembled into a wheel and a frame part which is a part other than the wheel, wherein the wheel and the frame part are wrapped at least from the left and right side surfaces. A bundling material for bundling the packing material by winding the material, the wheel and the frame part wrapped around the packing material so as to pass at least both side surfaces and the bottom surface side, and a top surface Proposed bicycle packaging box having a substantially rectangular parallelepiped shape with an internal space in which the package can be stored, and a fitting top lid that closes the top opening of the packaging box body (See Patent Document 3).

  The bicycle packing box described in Patent Document 3 can complete the work of storing and taking out the bicycle in one time, and exhibits the effect of effectively preventing scratches and breakage of wheels and frame parts during transportation. is there.

  Each of the bicycle packaging boxes described in Patent Documents 1 to 3 has the above-mentioned advantages, but generally, a cardboard box used for a conventional bicycle packaging box is generally in a state in which one cardboard sheet is folded in half. It is the smallest size, and in order to store and transport bicycles, the corrugated cardboard sheet must be large, so it can be saved in space and cost reduced when folded (stored and transported). It was disadvantageous in terms of improving portability. In order to achieve downsizing during folding, for example, it is necessary to increase the number of folding parts, and maintain the strength and flexibility before the folding parts are increased during assembly (storage and transportation). It was difficult.

  The present invention has been made in order to solve the above-described problems of the prior art, and is space-saving, cost-reduced, and portable based on a reduction in size (volume) during folding (storage / transport). It is an object of the present invention to provide a cardboard box for a bicycle capable of achieving both improvement and maintenance of strength and flexibility during assembly (when storing and transporting a bicycle).

  As a result of intensive studies to achieve the above object, the inventor has found that the above object can be achieved by devising a folding structure and appropriately selecting a corrugated cardboard sheet as a material.

In one embodiment of the cardboard box for a bicycle according to the present invention, when it is composed of two cardboard sheets, it is a developed view schematically showing one of the cardboard sheets before folding. In one embodiment of the cardboard box for bicycle according to the present invention, among the folds formed on the two wall surfaces facing each other, the folds facing each other are formed in a shifted positional relationship without facing each other. It is explanatory drawing which shows having shown typically.

  Hereinafter, an embodiment of a bicycle cardboard box according to the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1-7, the bicycle cardboard box 10 of the present embodiment is stored and transported in the folded state shown in FIG. 7, and stores and transports the bicycle in the assembled state shown in FIG. It is a cardboard box for bicycles used for.

  In the assembled state, it has a large rectangular parallelepiped box shape composed of two wall surfaces 1 and 2 facing each other, two side surfaces 3 and 4 facing each other, a top surface 5 and a bottom surface 6 facing the top surface 5. doing.

  The two wall surfaces 1 and 2 facing each other have two folds WL1 and WL2 (two folds WL3 and WL4 on the wall surface 2 formed so as to extend in parallel at a predetermined interval in the height direction). , See FIG. 9).

  The top surface 5 and the bottom surface 6 facing each other extend continuously from the wall surfaces 1, 2 and the side surfaces 3, 4, and the folds FL 1, FL 2 are two folds of the wall surface 1 on the top surface 5 side. As shown in FIG. 9, the creases WL <b> 3, FL <b> 4 are formed continuously with the two folds WL <b> 3, WL <b> 4 of the wall surface 2 so as to be formed continuously with the folds WL <b> 1, WL <b> 2. The fold lines FL5 to FL8 are formed continuously with the fold lines WL3 and WL4 (see FIG. 9), and the double structure (the flap F1 and the flap F2, and the flap F5 and the flap F6 (see FIG. 2) are substantially omitted during assembly). Each of the four flaps F1 to F4 is formed so as to constitute a completely overlapping structure (see FIG. 2 for the four flaps F5 to F8 on the bottom surface side).

  Further, the bicycle cardboard box 10 of the present embodiment can be folded into a small book shape by using a plurality of folds (see FIG. 7), while maintaining strength and flexibility. Bicycles can be stored and transported.

  As shown in FIG. 1, the cardboard box 10 for a bicycle according to the present embodiment is a hand for an operator to insert a hand to facilitate carrying work when storing and transporting the bicycle in an assembled state. Two insertion cuts 8 are formed on each of the two wall surfaces 1 and 2 (two hand insertion cuts 8 on the wall surface 2 are not shown).

  As described above, the cardboard box for a bicycle according to the present invention is suitably used when storing and transporting a bicycle, particularly a bicycle in a state of being disassembled into a wheel and a frame component that is a component other than the wheel.

  Here, “bicycle” means a two-wheeled vehicle driven by human power, and includes a bicycle for practical use and daily life such as a city cycle. However, in the present invention, the present invention can be particularly preferably used for a competition bicycle such as a road racer, a track racer, a mountain bike, and a BMX bike that are frequently transported to a competition venue.

  Further, the “frame component” means the entire remaining component obtained by removing the wheel from the bicycle. Specifically, in addition to a frame (including a front fork), a pedal, a saddle, a handle, a crank, a chain, a front derailleur, a rear derailleur, a brake, and the like are included.

  Further, the “decomposed state into wheels and frame parts” is sufficient as long as at least the wheels are removed from the bicycle, and the frame parts may be further disassembled. However, from the viewpoint of reducing the number of parts and facilitating packaging, it is preferable that the vehicle is disassembled into wheels and frame parts and is not further disassembled.

  The size of the cardboard box 10 for a bicycle according to the present embodiment varies depending on the type and size of the bicycle to be stored. In the case of a road racer, the range is 1000 to 1400 mm in width, 200 to 600 mm in depth, and 600 to 1000 mm in height. Preferably, the width is 1100 to 1300 mm, the depth is 300 to 500 mm, and the height is 700 to 900 mm.

  In the cardboard box 10 for a bicycle according to the present embodiment, as described above, the bicycle can be folded into a small book shape, and the bicycle is folded while maintaining strength and flexibility, and is stored and transported. It is possible. This is because the folding structure is devised and the corrugated cardboard sheet as a material is appropriately selected.

  With respect to the folding structure, two cardboard sheets 7 shown in FIG. 8 are connected and the steps shown in FIGS. 2 to 6 are performed, whereby the book can be folded into a small book shape shown in FIG.

  That is, first, two sheets of corrugated cardboard sheet 7 formed with fold lines WL1 and WL2 shown in FIG. In this case, you may connect by an adhesive tape etc., without using the glue allowance 71. FIG.

  Next, the two cardboard sheets 7 are folded so that the flaps F1 to F8 constituting the top surface and the bottom surface are opened as shown in FIG. 2 (second form). In addition, this 2nd form respond | corresponds to the form which each opened the flaps F1-F8 in the case of disassembly (folding) from the form (1st form) at the time of the assembly completion shown in FIG.

  Next, as shown in FIG. 3, the flaps F <b> 1 to F <b> 8 that constitute the top surface and the bottom surface are each reversed (third configuration).

  Next, as shown in FIG. 4, in one corner C <b> 1, one side surface 3 and a part up to the crease WL <b> 2 of one wall surface 1 continuous therewith are reversed and recessed inward ( (4th form).

  Next, as shown in FIG. 5, at the other corner C2, the other side surface 4 and the other wall surface 2 (the wall surface 2 on the side opposite to the wall surface 1 shown in FIG. 4) up to the fold line WL1. The part is folded in reverse so that it is recessed inward (fifth form).

  Next, as shown in FIG. 6, after the two corners C1 and C2 are sufficiently indented, the folds WL1 and WL3 (not shown) respectively located at the approximate centers of the opposing wall surfaces 1 and 2 are provided. It is made the form (6th form) just before folding along.

  Next, as shown in FIG. 7, a book shape is formed along the fold lines WL1 and WL3 (see FIG. 6; the fold line WL3 is not shown in FIG. 6) positioned at the approximate center of the opposing wall surfaces 1 and 2, respectively. A fully folded form (form when folding is completed) (seventh form).

  Further, as shown in FIG. 9, in the bicycle cardboard box 10 of the present embodiment, among the folds WL1 to WL4 formed on the two wall surfaces 1 and 2 facing each other, the folds facing each other (FIG. 9). In this case, it is preferable that the fold line WL1 and the fold line WL4, and the fold line WL2 and the fold line WL3) are formed in a shifted positional relationship without facing each other. With this configuration, it is possible to achieve both reduction in size (volume) during folding (storage / transport) and maintenance of strength during assembly (storage / transportation of the bicycle). When facing the folds facing each other, it is easy to apply the load in the same direction to the two folds at the same time. However, if the positional relationship is shifted from each other, the load in the same direction is prevented from being applied to the two folds at the same time. In addition, it is possible to prevent and maintain the strength during assembly (when storing and transporting the bicycle) due to the formation of a plurality of folds.

  Regarding the selection of corrugated cardboard sheets, the material used is the strength at the time of assembly (storage and transport of the bicycle) (specifically, rigidity, strength against external vibration and impact, prevention of breakthrough due to the sharp part of the bicycle, etc.) In addition, it is required to have adequate flexibility and shape following ability to prevent damage, deformation, etc. of the bicycle, and space saving based on downsizing of the dimensions (volume) during folding (storage / transport) Therefore, it is required to be inexpensive, lightweight, and easy to dispose and recycle. From this point of view, the bicycle corrugated cardboard box 10 of the present embodiment is composed of K7 front and back liners and a corrugated cardboard sheet using a 160g center core having a mountain density of B flute (mountain height of 3 mm). It is preferable that In addition to this, for example, a front / back liner of K6, a front / back liner of K5, or a combination of front and back of K7 / K6 / K5 may be used separately, and a 120 g center core may be used as the center core. Furthermore, although the density of the mountain is somewhat difficult to fold, an A flute (mountain height of 5 mm) of 160 g or 120 g may be used.

  Hereinafter, the present invention will be described more specifically with reference to examples. However, the present invention is not limited in any way by the following embodiments.

Example 1
A cardboard box for bicycles of Example 1 (width 1240 mm, depth 370 mm, height 760 mm) was produced. Specifically, two corrugated cardboard sheets 7 shown in the developed view shown in FIG. 8 are connected to each other at the glue margin 71 portion, and assembled into the shape of the cardboard box 10 for a bicycle shown in FIG. The bicycle cardboard box 10 is changed from the form shown in FIG. 1 (first form) to the form shown in FIG. 7 through the form (second form to sixth form) shown in FIGS. It is possible to make it the form (seventh form) folded in the book type shown.

  In this case, as shown in FIG. 9, the distance X between the side L1 of the wall surface 1 and the fold WL1 is equal to the distance Y between the fold WL1 and the fold WL2, and the fold WL2 and the side L2 of the wall 1 It was set larger than the distance Z between the two. That is, it was set to have a relationship of X = Y> Z. The opposing wall surfaces 2 were also formed so that the distances between the creases from the right side in FIG. 9 had the same relationship, and the creases opposing the two wall surfaces did not face each other. Specifically, as shown in FIG. 8, X = Y = 435 mm and Z = 370 mm were set.

  The bicycle cardboard box of Example 1 is assumed to store and transport a road racer. The height (radius) of the axle of this road racer wheel was 330 mm. This road racer has only a rear derailleur and does not have a front derailleur. In this road racer, the rear derailleur was disposed at a height of 600 mm in a state where the top and bottom of the frame member was reversed.
