Description

  The present invention relates to a foldable article storage container (folding container), and more particularly to improvement of a handle part (or a gripping part) provided on a side plate constituting the folding container and a peripheral structure thereof. .

  In general, a folding container has an upper frame, a bottom plate, and four side plates that are configured to be foldable between the upper frame and the bottom plate (for example, a pair of folding plates in a facing relationship and a pair of tilting plates in a facing relationship). It has. For example, in the folding container of Patent Document 1, a gripping concave portion is formed at a substantially central portion in the width direction at the end of the upper frame (upper frame) of the tilt plate. The grip recess is formed integrally with the tilt plate main body so as to be concave with respect to the outer surface (front surface) of the tilt plate while being convex with respect to the inner surface (back surface). Also, the amount of the recess for gripping and protruding from the inner surface (back surface) of the plate body is such that when the container is folded (ie when the tilt plate is laid sideways), the grip recess (projection on the back surface) is attached to the upper frame. The cover plate is set so as not to obstruct the closing operation of the cover plate and to be within the height range of the storage space secured inside the upper frame.

Utility Model Registration No. 3008772 (Full paragraph 0027 paragraph and gripping recess 15 shown in FIGS. 2, 3, 5 and 9)

  However, in the container of Patent Document 1, although the amount of protrusion from the inner surface (back surface) of the side plate main body is suppressed, the gripping recess protrudes not less than the inside of the container. When pulling out the article, the article is caught at the corner of the wall part (for example, the right-angled joint between the vertical wall and the horizontal wall) that constitutes the gripping concave part, and this hinders the removal of the article from the container. There is.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to construct a structure that does not hinder the loading and unloading of articles in a handle portion that is recessed in the main body of a folding container. .

In order to achieve the above object, the invention of claim 1 comprises at least a rectangular frame-shaped top frame, a bottom plate, and two side plates facing each other when standing, and an upper end portion of each side plate is provided on the top frame. When the container is folded, the two tilting plates are laid down and stored in the inner space of the upper frame, and the distal ends of the two tilting plates on the side away from the pivoting fulcrum overlap each other. In the folding container in which the upper side of the tilting plate is in an inclined storage posture in which the tip end portion is located above the rotation fulcrum, the tilting plate is disposed at the center of the tilting plate in the vertical and horizontal directions. A flat plate-shaped main body central portion that is parallel to the vertical line when the tilt plate is erected is provided, and is recessed in a concave shape with respect to the outer surface of the main body central portion , and bulges in a convex shape with respect to the inner surface of the main body central portion. The concave handle is The concave handle portion is formed into a body, and includes a heel wall corresponding to the bottom of the heel, an upper wall that provides a substantially horizontal finger allowance when the tilt plate is erected, a lower wall facing the upper wall, and the heel The left side wall and the right side wall located on the left and right sides of the wall are partitioned, and a substantially horizontal front wall portion that protrudes further outward than the outer surface of the central portion of the main body is continuous in front of the upper side wall of the concave handle portion. The integrated front wall portion and the upper side wall form a finger allowance, and the lower side wall of the concave handle portion is parallel to the upper side wall, and the lower side wall and the collar wall are perpendicular to each other. If the connecting portion between the lower side wall and the flange wall is located above the uppermost point of the tip portion of the tilt plate in the tilted storage posture, the concave handle portion The back wall and the lower side wall of the It is inclined to be lowered, characterized in where the coupling portion between the said lower wall 奧壁 was positioned below the uppermost point of the front end portion of the tilt plate of the inclined retracted position.

  According to a second aspect of the present invention, in the folding container according to the first aspect, a joint portion between the upper side wall and the eaves wall constituting the concave handle portion is formed to be curved so as to have an R shape. And

The invention according to claim 3, in the folded container according to claim 1 or 2, close to the upper end position of the tilt plate, the body middle dents concavely with respect extends laterally and the inner surface of the body central portion against the outer surface of the section strip protruding portion that bulges in a convex shape is formed, the upper wall of the strip protruding portion, said front wall to contact the lower end of the lower wall of the concave possession unit The left side wall and the right side wall are protruded from the outer surface of the central part of the main body and are interposed between the front wall part and the upper surface wall of the belt-like bulged part.

According to the first aspect of the present invention, the upper side wall of the concave handle portion provides a substantially horizontal hand allowance on the inner surface of the concave handle portion when the tilting plate stands up (that is, when the container is assembled). The back wall and the lower wall are partitioned in an outwardly inclined shape when the tilting plate stands . Therefore, even when the article contained in the container is pulled out from the inside, even if the article comes into contact with the wall on the back side of the concave handle part, the outer wall and the lower side wall are inclined downward (that is, inwardly inclined). Thus, the article is guided so as to be smoothly lifted, and a situation where the article is caught on the wall portion on the back side of the concave handle portion is avoided. In addition, since the upper side wall of the concave handle part and the substantially horizontal front wall part in front of the concave handle part are integrated, the hand allowance is constructed, resulting in a sufficient allowance or width. It becomes easy to put fingers. In addition, since it is possible to secure the allowance for fingers having a sufficient depth or width, the amount of protrusion of the concave handle portion to the inside of the tilt plate and the amount of projection of the front wall portion to the outside of the tilt plate are the minimum required. It can be kept in. Further, in the present invention, when the container is folded, the tip portions on the side away from the rotation fulcrum of the two tilting plates overlap each other, and the upper tilting plate is inclined so that the tip portion is located above the rotation fulcrum. Become posture. If the lower side wall of the concave handle portion is parallel to the upper side wall and the lower side wall and the eaves wall are connected at a right angle, the connection portion between the lower side wall and the eaves wall is in the tilted storage posture of the tilt plate. In the present invention, the upper wall and the lower side wall of the concave handle portion are inclined so that they are outwardly lowered when the tilt plate is raised, and the lower side wall and the eaves wall are located above the uppermost point of the tip part. And the connecting portion were positioned below the uppermost point of the front end portion of the tilted and stowed tilting plate. As a result, the height of the upper frame that provides the inner space necessary for storing the tilt plate can be made as low as possible, and as a result, the overall height of the container during folding can be made as low as possible.

  According to claim 2, when the article is lowered from the outside (upper) to the middle (lower) of the container by forming the connecting portion between the upper side wall and the eaves wall constituting the concave handle part in a curved shape. In addition, the article is less likely to be caught with respect to the coupling portion. Therefore, even if the back side of the concave handle portion bulges into the container, the article can be easily put in and out of the container due to the synergistic effect with the structure of claim 1.

According to the configuration of the third aspect, the strength of the tilt plate can be increased by the pair of side walls.

  Hereinafter, an embodiment in which the present invention is applied to a folding container will be described. FIG. 1 shows an outline in a state in which a folding container is assembled. As shown in FIG. 1, the container has a planar rectangular and frame-shaped upper frame 1, a bottom plate 2 that forms a planar rectangular shape corresponding to the upper frame 1, and the upper frame 1 and the bottom plate 2 are opposed to each other. A pair of tilt plates (short side plates) 3, a pair of folded plates (long side plates) 5 that are also opposite to each other, and a pair of lids 9 that can be opened and closed with respect to the upper frame 1 are provided. These container components (1, 2, 3, 5 and 9) are made of plastic such as synthetic resin. Each of the tilt plates 3 is rotatably attached to the upper frame 1 by an attachment shaft 3a.

(About folded plates)
Each of the folding plates 5 is configured by connecting two upper and lower plates (the long side upper plate 6 and the long side lower plate 7) so that they can be bent inward at the connecting portion 8. The long side upper plate 6 is rotatably attached to the upper frame 1 by an attachment shaft 6a, and the long side lower plate 7 is rotatably attached to the bottom plate 2 by an attachment shaft 7a. Therefore, if each of the folding plates 5 is erected so that the long side upper plate 6 and the long side lower plate 7 are in a single vertical surface state, the respective vertical plates 3 are vertically erected as shown in FIG. A container is assembled. On the contrary, after each tilting plate 3 is tilted to the inside of the upper frame 1, if each folding plate 5 is folded inward by the connecting portion 8, the container is folded. When folded, the lower end of the side wall of the upper frame 1 comes into contact with the upper end of the side wall of the bottom plate 2, and at that time, an internal space (that is, a storage space for the side plate) is secured between the upper frame 1 and the bottom plate 2 (FIG. 5). In the internal space, two folded plates 5 in a folded state and two tilted plates 3 placed on the folded plate 5 are stored.

  2 and 3 show details of the long-side upper plate 6 and the long-side lower plate 7 constituting the folded plate 5. Each of the long side upper plate 6 and the long side lower plate 7 has a bilaterally symmetric shape with the center dividing line X in between.

  As shown in FIG. 2A, the long-side upper plate 6 is configured as a single plate that is relatively thin and has a horizontally long rectangular shape. The upper end of the long upper plate 6 is provided with a shaft support structure 61 for rotatably mounting the upper plate 6 with respect to the upper frame 1, and the connecting portion is provided at the lower end of the long upper plate 6. 8 is provided.

  As shown in FIGS. 2A and 3A, a distance L (for example, from the upper edge of the long upper plate 6 to the main body outer surface 63 of the long upper plate 6 (the surface that becomes the front side when the container is assembled) is provided. At a position lowered by 10 to 15 mm), a handle rib 64 extending in the lateral direction (horizontal direction) is projected. When the container is assembled, that is, when the folded plate 5 is erected, the handle rib 64 functions as a handle portion or a grip portion, and provides a horizontal finger allowance on its lower surface (abdomen surface). The lateral length of the handle rib 64 is, for example, about 70 to 100 mm, and the protruding amount (or width) h of the handle rib 64 from the outer surface 63 of the upper plate body is, for example, about 5 to 15 mm. As shown in FIG. 4, the protruding amount h of the handle rib 64 is set so as not to exceed the outer dimensions in plan view of the container during assembly defined by the planar dimensions of the upper frame 1 and the bottom plate 2. For this reason, the leading end (protruding end) of the handle rib 64 does not protrude outside the side wall 11 of the upper frame 1, and the handle rib 64 does not become an obstructive protrusion.

  As shown in FIGS. 2 (A) and 3 (A), the outer surface 63 of the long upper plate 6 is positioned directly above the handle rib 64 and the long side lower plate 7 (described later) when the folded plate 5 is folded. A plurality of vertical ribs 65 are formed at positions corresponding to the horizontal ribs 74. Each of the vertical ribs 65 extending in the vertical direction (vertical direction) is connected to the upper surface (back surface) of the handle rib 64 extending in the horizontal direction and has a right-angled connection relationship with the handle rib 64. The rigidity is reinforced on the upper surface side.

  As shown in FIG. 2B, the long side lower plate 7 is configured as a horizontally long rectangular single plate that is relatively thin and matches the long side upper plate 6. A connecting structure 71 for configuring the connecting portion 8 together with the connecting structure 62 of the long side upper plate is provided at the upper end portion of the long side lower plate 7, and the lower plate 7 is provided at the lower end portion of the long side lower plate 7. A pivot support structure 72 is provided for pivotally attaching the base plate 2 to the bottom plate 2.

  As shown in FIG. 2 (B) and FIGS. 3 (B) and 3 (C), the main body outer surface 73 of the long lower plate 7 has a receiving convex portion extending in the lateral direction (horizontal direction) in the vicinity of the lower end portion thereof. The horizontal rib 74 is projected. The horizontal rib 74 extends substantially over the entire length of the long side lower plate 72 in the laterally long direction. At the tip of the horizontal rib 74, projecting piece-like cover portions 74a extending in a substantially vertical direction are provided in some places. .

  When the container is folded, as shown in FIG. 5, the long side upper plate 6 and the long side lower plate 7 are substantially horizontal, and the main body outer surface 63 of the long side upper plate and the main body outer surface 73 of the long side lower plate face each other. The folding plate 5 is folded so as to be in a state of being touched. At this time, the longitudinal ribs of the long upper plate 6 folded back by 180 ° at the connecting portion 8 with respect to the ends (the upper ends in FIG. 5) of the horizontal ribs 74 of the long lower plate 7 laid on the bottom plate 2. The tip of 65 (the lower end in FIG. 5) abuts. Since the tilt plate 3 is placed on the long side upper plate 6 of the folded folded plate 5 in a lying state, the total load of the tilt plate 3 and the long side upper plate 6 is in the vertical contact state in which they are in mutual contact. It is transmitted to the long side lower plate 7 and the bottom plate 2 via the rib 65 and the horizontal rib 74. That is, the vertical load caused by the contents stored in the container (the tilt plate 3 or the like) at the time of folding is reliably transmitted and supported by the vertical rib 65 and the horizontal rib 74.

  The protrusion amount h of the handle rib 64 is suppressed so that the handle rib 64 does not interfere with the long side lower plate 7 when the folding plate 5 is folded as shown in FIG. The application of the handle rib 64 to the upper plate 6 does not hinder the folding operation of the folding plate 5.

  As described above, according to the present embodiment, the long side plates 6 and 7 constituting the folding plate 5 are configured to be relatively thin, and function as a handle portion or a gripping portion when the folding plate 5 stands up. By projecting the handle rib 64 on the main body outer surface 63 of the long upper plate, the container can be lifted and carried by placing the finger on the handle rib 64. Further, the vertical load when the side plate 3 is laid down on the folded plate 5 in the folded state can be reliably transmitted and supported between the vertical rib 65 and the horizontal rib 74, and the folding caused by the vertical load can be performed. The deformation of the plate 5 can be prevented beforehand.

(Example of folding plate change)
As shown in FIG. 6, when the folding plate 5 is folded and the vertical rib 65 of the long upper plate 6 and the horizontal rib 74 of the long lower plate 7 come into contact with each other, the handle ribs 64 cooperate with it. The protruding amount h of the handle rib 64 may be set so that the front end (lower end in FIG. 6) abuts the main body outer surface 73 of the long lower plate. According to this modification, the upper plate vertical rib 65 and the lower plate horizontal rib 74 and the upper plate handle rib 64 and the lower plate outer surface 73 are in a folded state due to the cooperative simultaneous contact. The performance of transmitting and supporting a vertical load when another object (in this case, the tilt plate 3) is placed on the folded plate 5 is further enhanced. Further, in the configuration shown in FIG. 5 or FIG. 6, when the folding plate 5 is folded, not only the longitudinal rib 65 of the long upper plate abuts the horizontal rib 74 of the long lower plate but also the handle rib of the long upper plate. The handle ribs 64 and / or horizontal ribs 74 may be positioned so that 64 can also contact the horizontal ribs 74 of the long lower plate. In this case, the mutual contact between the handle rib 64 and the horizontal rib 74 can prevent, for example, the long upper plate 6 from rattling in the horizontal direction of FIG. 5 or FIG.

(About the tilt plate)
7 and 8 show details of the tilt plate 3. The shape of the tilt plate 3 is symmetric with respect to the center dividing line Y. As shown in FIGS. 7 and 8, the tilt plate 3 is configured as a single plate that is relatively thin and rectangular when viewed from the front. In particular, as shown in FIGS. 7A and 7B, the plate thickness of the tilt plate main body 30 is generally uniform, and the thickness of the central portion 30a of the main body 30a apart from the four upper, lower, left and right end portions is uniform. Moreover, it has a flat plate shape. A shaft support structure 31 for rotatably mounting the tilt plate 3 to the upper frame 1 is provided at the upper end of the tilt plate 3. On the other hand, the lower end portion of the tilt plate 3 is provided with an engagement portion 32 for engaging with a part of the bottom plate 2 during assembly of the container to ensure the upright posture of the tilt plate 3.

  In the vicinity of the upper end portion and the lower end portion of the tilt plate 3, strip-shaped bulging portions 33 extending in the horizontal direction (horizontal direction) are respectively formed so as to project, and in the vicinity of the left and right end portions of the tilt plate 3, the vertical direction (vertical direction) A total of four strip-shaped bulging portions 34A and 34B extending in the direction of the projection are formed. The upper and lower lateral belt-like bulging portions 33 and the left and right vertical belt-like bulging portions 34A surround the main body central portion 30a from four directions. As shown in FIGS. 7B, 8A, and 8B, the upper lateral belt-like bulged portion 33 is parallel to the flat plate-like main body central portion 30a and from the main body central portion 30a. A bulging portion top surface 331 at a position protruding outward, and two connecting surfaces 332 that are above and below the bulging portion top surface 331 and connect the bulging portion top surface 331 to the tilt plate body 30. , 333 in total. As a result, the upper lateral band-shaped bulging portion 33 becomes a convex portion or a ridge protruding outward from the surface of the tilt plate main body 30, but is depressed with respect to the back surface of the tilt plate main body 30. It is a recess or a lateral groove. The basic structure of the other belt-shaped bulging portions (33, 34A and 34B) is the same as that of the upper lateral belt-shaped bulging portion 33.

  As shown in FIG. 1, FIG. 7 and FIG. 8, at the center position in the width direction of the tilt plate main body 30 and between the upper end of the main body and the upper lateral belt-like bulged portion 33, the container is transported. A concave handle 40 is provided as a handle for placing a finger on the handle. The concave handle portion 40 includes a heel wall 41 corresponding to the bottom of the heel, an upper side wall 42 and a lower side wall 43 positioned above and below, and a left side wall 44 and a right side wall 45 positioned on the left and right sides of the heel wall 41. And defined by these five walls 41 to 45. The concave handle 40 has a concave-convex shape that dents in a concave shape with respect to the outer surface (front surface) of the tilt plate main body 30 and bulges in a convex shape with respect to the inner surface (back surface) of the main body. And it is integrally formed with respect to the tilt plate 3 as an uneven shape that does not penetrate the inside and outside of the tilt plate main body 30.

  As shown in FIGS. 8A and 8B, when the tilting plate 3 stands upright, the upper wall 42 of the concave handle portion is substantially horizontal, while the wall 41 is inclined with respect to the vertical line. It is provided so as to be inclined outwardly (that is, upward) by θ1 (θ1 is a minute acute angle). Here, the vertical line means a virtual line perpendicular to the ground or the installation surface, and the tilt plate body 30 at the time of vertical standing is parallel to the vertical line. Further, the lower side wall 43 facing the upper side wall 42 is not only non-parallel to the upper side wall 42 but also falls outwardly by an inclination angle θ2 (θ2 is an acute angle larger than θ1) with respect to the vertical line or the tilt plate main body 30 ( That is, it is provided as an inclined wall inclined inwardly). By setting the inclination angle of the wall 41 and the lower side wall 43, the angle (coupling angle) formed between the wall 41 and the lower side wall 43 is an obtuse angle.

  Further, in the concave handle portion 40, the joint portion between the upper side wall 42 and the eaves wall 41 is curved and formed in an R shape so as not to be angular. Further, a substantially horizontal front wall portion 47 protruding outward (frontward) from the outer surface of the tilt plate main body 30 is continuously formed in front of the upper side wall 42. The forward protrusion amount of the front wall portion 47 corresponds to the protrusion amount of the lateral belt-like bulged portion 33 from the tilt plate body 30 (see FIG. 8B). The upper side wall 42 and the front wall portion 47 construct a substantially horizontal integrated wall portion, and the lower surfaces of the wall portions (42, 47) provide a substantially horizontal finger allowance. The left side wall 44 and the right side wall 45 extending in the vertical direction are respectively positioned on the left and right sides of the integrated wall portions (42, 47), and also serve as reinforcing ribs that reinforce the strength of the integrated wall. Yes.

  According to the tilting plate 3 of the present embodiment, when the tilting plate 3 stands vertically (that is, when the container is assembled), the upper side wall 42 of the concave handle portion 40 and the front wall portion 47 continuously formed therewith are integrated. Since the finger allowance is constructed, it is possible to carry the container by placing the finger there. In addition, the upper wall 42 projecting toward the inner surface side of the tilt plate main body 30 and the front wall portion 47 projecting toward the outer surface side of the tilt plate main body 30 ensure a sufficient allowance for fingers having sufficient depth or width. Therefore, not only is it easy to place fingers, but also the amount of protrusion of the concave handle 40 toward the inner surface of the tilt plate main body and the amount of protrusion of the front wall 47 to the outer surface of the tilt plate main body are kept to the minimum necessary. be able to.

  When the container is assembled, the lower side wall 43 of the concave handle portion 40 partitions the lower end portion of the concave handle portion 40 into a downwardly inclined shape that is not parallel to the upper side wall 42. Therefore, even when the article stored in the container is pulled out from the inside, even if the article comes into contact with the back side wall portion of the concave handle portion 40, the lower side wall 43 has an outer downward inclination (that is, an inner upward inclination). The article is guided so as to facilitate the lifting operation, and is not caught by the back side wall portion of the concave handle portion 40. Moreover, even if the back side of the concave handle portion 40 bulges into the container, the connecting portion of the upper wall 42 and the heel wall 41 constituting the concave handle portion is curved and formed into an R shape. When the article is dropped from the outside (top) to the inside (bottom), it becomes difficult to catch the R-shaped portion. As described above, according to the present embodiment, articles can be smoothly put in and out without being caught by the inner protrusion of the tilting plate 3 in the standing state.

  In the folding container of the present embodiment, due to the dimensional relationship between the overall height of the tilt plate 3 and the lateral length of the folding plate 5, when the container is folded, as shown in FIG. It is necessary to lay the tilt plate 3 in an inclined state while overlapping the lower end portions thereof. In particular, in the case of the left side tilt plate 3 omitted in the middle of FIG. 9 and indicated by a solid line, the lower end portion is laid down on the right side tilt plate 3 (shown by a virtual line) so that the lower end portion is laid down. Lay down in an inclined state that is relatively above the upper end. If the lower side wall 43 constituting the concave handle portion 40 of the tilt plate 3 is provided in parallel to the upper side wall 42, and the lower side wall 43 and the collar wall 41 are coupled at substantially right angles, The assumed joint between the side wall 43 and the heel wall 41 (shown in broken lines in FIG. 9) would have protruded significantly upward. In this respect, in the tilt plate 3 of the present embodiment, the wall 41 is an outwardly inclined wall with an inclination angle θ1 and the lower wall 43 is an outwardly inclined wall with an inclination angle θ2 that is not parallel to the upper wall 42. Thus, the coupling angle between the lower side wall 43 and the eaves wall 41 is obtuse, and the amount or height at which the coupling portion between the lower side wall 43 and the eaves wall 41 protrudes upward is suppressed. Therefore, according to the present embodiment, it is possible to set the height of the upper frame 1 that provides the inner space necessary for storing the laying board 3 laid sideways lower than before, and as a result, when folded. It is possible to reduce the overall height of the container as much as possible.
