Description

  The present invention relates to a container having an open door pivotally supported by a hinge mechanism.

  A container that accommodates various kinds of luggage usually has a substantially rectangular parallelepiped hollow structure, and a door (hereinafter referred to as “open door”) for loading and unloading goods on at least one of a pair of wife faces and a pair of side faces. Is also provided.). Such a container is provided with corner pillars at each of the four corners in plan view, and a position where a wife face not provided with a door and a side face provided with a door intersect among these four corner pillars. For example, the vicinity of the corner post arranged in FIG. 8 has a structure as shown in FIG. That is, the corner pillar 100 having the outer member 102 and the inner member 104 is provided with a hinge mechanism 110, and the opening door 20 provided on the side surface of the container is attached to the corner pillar 100 through the hinge mechanism 110 so as to be freely opened and closed. It has been. A waterproof rubber 74 having a fin portion 76 and an inner fin portion 78 is attached to the edge of the open door 20, and the fin portion 76 and the inner fin portion 78 are in close contact with the inner member 104, so Airtightness is maintained. On the other hand, Patent Document 1 discloses a container whose capacity has been expanded without exceeding the loading limit by devising the upper beam located at the upper part of the side surface.

  Here, the container is desired to further expand the capacity and the opening, and as one method for realizing it, for example, the thickness of the corner post 100 shown in FIG. 8 is reduced. The method of doing is mentioned. Specifically, the amount of protrusion of the inner member 104 toward the indoor side (right side in the figure) may be reduced within a range that maintains the strength required for the corner post 100. However, if the protruding amount of the inner member 104 is reduced, the opening door 20 also needs to shift to the wife surface side (left side in the figure) accordingly, so the radius of the rotation locus of the waterproof rubber 74 when the opening door 20 is opened and closed is increased. There is a possibility that the open door 20 may be closed in a state where the tip of the fin portion 76 becomes small and is wound inside the inner member 104 (right side in the drawing). In such a state, the waterproof rubber 74 cannot play its original role.

  This invention is made | formed in view of the said subject, The place made into the objective is to prevent the entrapment of the waterproof rubber of an opening door at the time of enlarging the opening part of a container.

(Aspect of the Invention)
The following aspects of the present invention exemplify the configuration of the present invention, and will be described separately for easy understanding of various configurations of the present invention. Each section does not limit the technical scope of the present invention, and some of the components of each section are replaced, deleted, or further while referring to the best mode for carrying out the invention. Those to which the above components are added can also be included in the technical scope of the present invention.

  (1) An opening door pivotally supported by a hinge mechanism provided on the corner pillar is provided on at least one surface, and the corner pillar in the closed state of the opening door is provided at an edge portion along the corner pillar of the opening door. A waterproof rubber having a fin portion that is in close contact with the side surface of the container, wherein the hinge mechanism is a cylindrical or columnar rotating portion that is rotatably attached to the corner post; and A rotation part and a connection part that connects the door, and the rotation trajectory of the tip of the waterproof rubber fin when the door is opened and closed intersects with the side of the corner pillar. Corresponding to the width, the rotating portion has an outer diameter that is as small as possible, and is disposed so that its rotating shaft is as close as possible to the end face side (Claim 1).

  The container described in this section is provided with an open door for loading and unloading luggage on at least one surface, and the open door is pivotally supported by a hinge mechanism provided on a corner post. In addition, a waterproof rubber having a fin portion is fixed to an edge portion along the corner column of the door, and the fin portion of the waterproof rubber is a container with respect to the corner column in a state where the door is closed. Close contact from the side of the. That is, the open door here is provided on the side of the container, and the waterproof rubber fin fixed to the edge of the open door is in the state where the open door is closed and the front of the open door. It adheres to the corner pillar from the side.

  And the hinge mechanism which pivotally supports the above opening doors is provided with the rotation part and the connection part. The rotating portion has a cylindrical shape or a columnar shape, and is rotatably attached to the corner column so that the rotation axis thereof is parallel to the extending direction (vertical direction) of the corner column. The connecting portion connects the opening door to the rotating portion, and is fixed to the rotating portion by a fixing method such as welding. As a result, the opening door opens and closes with the rotation of the rotating part. In addition, the rotating portion of the hinge mechanism has an outer diameter size and an arrangement of the rotation shaft corresponding to the width of the side surface of the corner column provided with the hinge mechanism (the width in the direction orthogonal to the end face of the container). Is set.

  Specifically, the size of the outer diameter and the arrangement of the rotation shaft are set so that the rotation locus of the tip of the waterproof rubber fin portion intersects the side surface of the corner post when the door is opened and closed. At this time, the outer diameter of the rotating part is set to the smallest possible size within a range that maintains the strength with which the door can be rotatably supported, for example, and the rotating shaft of the rotating part is, for example, the rotating part. As long as the peripheral part of the container does not protrude from the corner post to the end face side, it is arranged at a position as close as possible to the end face side of the container. Thereby, according to the width of the side surface of the corner post, the opening that is pivotally supported via the rotating part and the connecting part in a state where the radius of the rotation locus at the tip of the fin part is kept as large as possible. Is shifted to the end face of the container. Therefore, even if the width of the side surface of the corner post is smaller than the conventional one, the waterproof rubber and the corner post such that the rotation locus of the tip of the waterproof rubber fin fixed to the door intersects the side of the corner post. The positional relationship is maintained. For this reason, even if the opening of the container is enlarged by reducing the width of the corner pillar, the waterproof rubber entanglement caused by the tip of the waterproof rubber fin being difficult to contact the side face of the corner pillar is prevented. It is.

A hinge pin, and a hinge pin fixed to each of the through holes in a state in which an upper end and a lower end are inserted through the through holes of the pair of hinge lugs, and the rotating portion has a cylindrical shape and has a central hole When the hinge pin is inserted into the hinge pin, the hinge pin is rotatably attached to the hinge pin, and the pair of hinge lugs are in a cross-sectional view perpendicular to the vertical direction. A container in which the through-hole is provided at a position where the rotation axis of the rotating part is as close to the end face as possible, as long as it does not protrude into the surface (Claim 2).

  In the container described in this section, the hinge mechanism further includes a pair of hinge lugs and a hinge pin, and the pair of hinge lugs is fixed to a notch provided in the corner post. This notch is provided at the end of the corner post on the side of the container so as to extend in the vertical direction, and a pair of hinge lugs are fixed to the upper and lower ends of such a notch. Each of the pair of hinge lugs is provided with a circular through hole, and the through holes are arranged to face each other while being fixed to the notch portion of the corner post. Then, the upper and lower ends of the hinge pins are inserted into the through holes of the pair of hinge lugs, and the hinge pins are fixed to the through holes in this state.

  On the other hand, the rotating part of the hinge mechanism has a cylindrical shape, and is rotatably attached to the hinge pin by inserting the hinge pin through the center hole thereof. For this reason, prior to fixing to the hinge lug, the hinge pin is inserted through the central hole of the rotating portion in advance, and is fixed to the pair of hinge lugs in this state. In the hinge mechanism having such a configuration, the position of the central axis of the rotating portion is determined by the positions of the through holes provided in the pair of hinge lugs. Therefore, in the container described in this section, the rotation axis of the rotating portion is as close to the wife surface as possible in a range in which the rotating portion does not protrude from the end of the hinge lug to the wife surface in a cross-sectional view orthogonal to the vertical direction. A through hole of a pair of hinge lugs is provided at such a position. As a result, even if the width of the corner post is reduced, the rotation axis of the rotary unit is disposed at an appropriate position in consideration of the width of the corner post and the outer diameter of the rotary unit. Rubber entrainment is more reliably prevented.

  (3) In the above paragraphs (1) and (2), the corner pillar includes an outer member fixed so that the lining plate and the outer plate are installed on the indoor side and the opposite side of the wife surface, and the vertical direction An inner member fixed to the outer member from the inside of the room, and two outer portions corresponding to the tips of the two U-shaped leg portions; At least one hinge mechanism provided on the member, and the inner member is fixed to the outer member on the interior side surface of the flat portion located between the two U-shaped legs. A container having a size that is as close as possible to a plane defined by a surface on the indoor side of the lining plate in a state (Claim 3).

  In the container described in this section, the corner post includes an outer member and an inner member, and at least one hinge mechanism referred to in the above items (1) and (2) is provided in the outer member. A lining plate and an outer plate are fixed to the outer member so as to be installed on the indoor side and the opposite side of the end face of the container. At this time, the outer plate is fixed to the portion where the inner plate is fixed in a state where the inner plate is overlapped on the indoor side, and the outer plate is connected to the indoor portion at the portion where the outer plate of the outer member is fixed. It is fixed in a state of being stacked on the opposite side. Further, the inner member has a U-shaped cross section perpendicular to the vertical direction, and two portions corresponding to the tips of the two U-shaped leg portions are connected from the indoor side to the outer member. Fixed. At this time, the inner member is fixed so that the plane portion located between the two U-shaped leg portions is parallel to the end face of the container.

  Furthermore, the inner member is fixed to the outer member, and the indoor side surface of the flat portion described above is fixed to the outer member, with respect to the plane defined by the indoor side surface of the lining plate. The size is as close as possible. The size of the inner member in this case is the length of the portion corresponding to the U-shaped leg portion that defines the position of the planar portion of the inner member when the inner member is fixed to the outer member. Is shown. Further, the expression “approach as close as possible” indicates that the approach is as close as possible within the range that maintains the strength required for the corner post. As a result, the corner column of the container described in this section has a smaller amount of protrusion to the indoor side than the corner column of the conventional container, so the width of the opening of the opening door provided on the container side surface Both the capacity of the container will be expanded. Furthermore, while the width of the opening on the side surface of the container is increased in this way, the waterproof rubber and the corner column are arranged such that the rotation locus of the tip of the waterproof rubber fin fixed to the open door intersects the side surface of the corner column. Since the positional relationship is maintained, waterproof rubber is prevented from being caught.

Is arranged.

  Next, the hinge mechanism 62 provided on the corner post 32 will be described in detail with reference to FIGS. FIG. 5 is an enlarged view of one of the hinge mechanisms 62 shown in FIG. 3B. The hinge mechanism 62 includes a rotating portion 64, a connecting portion 66, and a cylindrical portion in this embodiment. A pair of hinge lugs 68 and a cylindrical hinge pin 70 are provided. The pair of hinge lugs 68 are welded and fixed to the upper end and the lower end of the notch 58 formed in the corner post 32. More specifically, as shown in FIG. 6, the notch portion 58 is formed from a part of the outer portion 40 of the outer member 34 to the overhang portion 48, and each of the hinge lugs 68 includes the notch portion 58. It is fixed by welding to both the formed outer portion 40 and the overhang portion 48. Each of the hinge lugs 68 includes a circular through hole 68a. As shown in FIG. 5, the upper end side of the hinge pin 70 is inserted into the through hole 68a of the upper hinge lug 68 in the figure, and the lower side in the figure. The lower end side of the hinge pin 70 is inserted into the through hole 68a of the hinge lug 68. The hinge pin 70 is welded to both the pair of hinge lugs 68.

  The rotating portion 64 is held so as to be rotatable about the rotation axis c with respect to the hinge pin 70 in a state where the hinge pin 70 is inserted into the center hole 64a. A washer 72 is installed between the lower end of the rotating portion 64 and the hinge lug 68 disposed on the lower side in the drawing. Further, referring to FIG. 7A, the connecting portion 66 has a bent plate shape in this embodiment, and the left end portion in FIGS. 5 and 7A is a peripheral portion of the rotating portion 64. 64b is fixed by welding. And as shown to Fig.7 (a), the open door 20 installed in the side surface 18 (refer FIG. 1) of the container 10 is weld-fixed by the connection part 66. As shown in FIG. A waterproof rubber 74 is fixed to the left end of the open door 20 in the drawing, and the waterproof rubber 74 has a fin portion 76 and an inner fin portion 78. In the closed state of the open door 20 shown in FIG. 7A, the tip of the fin portion 76 is in close contact with the side surface 56 of the corner column 32, and the tip of the inner fin portion 78 is in close contact with the indoor side surface 54 a of the corner column 32. .

  Here, in FIG. 7B, when the open door 20 is opened and closed, the rotation locus t drawn before the tip of the fin portion 76 of the waterproof rubber 74 comes into close contact with the side surface 56 or after leaving the side surface 56 is virtually illustrated. It is shown in the figure. As shown in the figure, the rotation trajectory t is centered on the rotation axis c of the rotating unit 64 that rotates with respect to the hinge pin 70. In this embodiment, the position of the through hole 68a provided in the hinge lug 68 and the outer diameter d of the rotating portion 64 are set so that the rotating shaft c is arranged as far as possible on the left side in FIG. . In other words, the through hole 68a of the hinge lug 68 that defines the position of the hinge pin 70 with which the rotating portion 64 rotates relatively is shown in the drawing in which the peripheral portion 64b of the rotating portion 64 is more than the hinge lug 68 in a sectional view in FIG. As long as it does not protrude to the left side, it is provided on the left side in the figure as much as possible.

  At this time, in order to move the central axis c to the left side in the figure, it is advantageous that the outer diameter d of the rotating portion 64 is smaller. For this reason, the outer diameter d of the rotating part 64 and the outer diameter of the hinge pin 70 on which the rotating part 64 relatively rotates are as small as possible within a range of strength that can pivotally open and close the door 20. Yes. And the rotation locus t centering on the rotation axis c arranged as described above intersects with the side surface 56 of the corner pillar 32 having the inner member 50 having the size as shown in FIG. Yes. 7 shows the structure in the vicinity of one corner pillar 32A of the two corner pillars 32A and 32B shown in FIG. 2B, but the vicinity of the other corner pillar 32B is also shown. 7 has an equivalent structure that is upside down.

  Now, according to the embodiment of the present invention configured as described above, the following operational effects can be obtained. That is, in the container 10 according to the embodiment of the present invention, as shown in FIG. 1 and FIG. 2, the open door 20 for taking in and out the luggage is composed of one wife face 14 and both side faces 16 and 18. The open door 20 is pivotally supported by a hinge mechanism 62 provided on the corner post 32. Further, a waterproof rubber 74 (see FIG. 7) having a fin portion 76 is fixed to an edge portion along the corner pillar 32 of the door 20, and the fin portion 76 of the waterproof rubber 74 is connected to the door 20. In the closed state (the state shown in FIG. 7A), the corner column 32 is in close contact with the side surface 18 of the container 10. That is, the open door 20 here indicates the open door 20 provided on the side surface 18 (or the side surface 16) of the container 10, and a fin portion 76 of the waterproof rubber 74 fixed to the edge of the open door 20. However, the door 20 is in close contact with the corner post 32 from the front side (the lower side in FIG. 7A) of the door 20 with the door 20 closed.

  And the hinge mechanism 62 which pivotally supports the above opening doors 20 is provided with the rotation part 64 and the connection part 66, as shown in FIG.5 and FIG.7. The rotating portion 64 has a cylindrical shape in the illustrated example, and is rotatable with respect to the corner column 32 so that the rotation axis c thereof is parallel to the extending direction of the corner column 32 (vertical direction in FIG. 5). It is attached. The connecting portion 66 connects the opening door 20 to the rotating portion 64 and is fixed to the rotating portion 64 by a fixing method such as welding. As a result, the opening door 20 opens and closes with the rotation of the rotating unit 64. Further, the rotating portion 64 of the hinge mechanism 62 corresponds to the width of the side surface 56 of the corner post 32 provided with the hinge mechanism 62 (the width in the left-right direction in FIG. 7) and the rotation axis of the outer diameter d. The arrangement of c is set.

  Specifically, the rotation portion 64 has a size of the outer diameter d and a rotation axis so that the rotation trajectory t of the tip of the fin portion 76 of the waterproof rubber 74 intersects the side surface 56 of the corner post 32 when the door 20 is opened and closed. The arrangement of c is set. At this time, the outer diameter d of the rotating part 64 is set as small as possible within a range that maintains the strength with which the opening door 20 can be rotatably supported, and the rotating shaft c of the rotating part 64 is The peripheral portion 64b of the rotating portion 64 is disposed at a position as close as possible to the end surface 12 side of the container 10 within a range that does not protrude from the corner post 32 to the end surface 12 side (left side in FIG. 7). Thereby, according to the width | variety of the side surface 56 of the corner pillar 32, sufficient radius was ensured in the connection part 66 for the radius of the rotational locus t of the fin part 76 mentioned above to be kept as large as possible. In the state, the position of the opening door 20 that is pivotally supported via the rotating portion 64 and the connecting portion 66 is shifted to the end surface 12 side of the container 10. Therefore, even if the width of the side surface 56 of the corner post 32 is smaller than the conventional width, the rotation locus t of the tip of the fin portion 76 of the waterproof rubber 74 fixed to the opening door 20 intersects with the side surface 56 of the corner post 32. In addition, the positional relationship between the waterproof rubber 74 and the corner post 32 can be maintained. For this reason, even if the opening of the container 10 is enlarged by reducing the width of the corner pillar 32, the waterproof rubber 74 is caused by the tip of the fin portion 76 of the waterproof rubber 74 being difficult to contact the side surface 56 of the corner pillar 32. Can be prevented.

  In the container 10 according to the embodiment of the present invention, as shown in FIGS. 5 and 6, the hinge mechanism 62 further includes a pair of hinge lugs 68 and a hinge pin 70. It is fixed to a notch 58 provided in the corner post 32. The notch 58 is provided at the end of the corner column 32 on the side surface 18 side (lower side in FIG. 6) of the container 10 so as to extend in the vertical direction. A pair of hinge lugs 68 are fixed to the lower ends. Each of the pair of hinge lugs 68 is provided with a circular through hole 68a, and the through holes 68a face each other while being fixed to the notch 58 of the corner post 32. The upper and lower ends of the hinge pins 70 are inserted into the through holes 68a of the pair of hinge lugs 68, and the hinge pins 70 are fixed to the respective through holes 68a in this state.

  On the other hand, the rotating portion 64 of the hinge mechanism 62 has a cylindrical shape, and is rotatably attached to the hinge pin 70 by inserting the hinge pin 70 through the center hole 64a. For this reason, prior to fixing to the hinge lug 68, the hinge pin 70 is inserted through the center hole 64a of the rotating portion 64 in advance, and is fixed to the pair of hinge lugs 68 in this state. In the hinge mechanism 62 having such a configuration, the position of the central axis c of the rotating portion 64 is determined by the position of the through hole 68 a provided in the pair of hinge lugs 68. Therefore, the container 10 according to the embodiment of the present invention is as far as possible of the rotating portion 64 as long as the rotating portion 64 does not protrude from the end of the hinge lug 68 to the left side in the drawing in the sectional view of FIG. A through hole 68a of a pair of hinge lugs 68 is provided at a position where the rotation axis c approaches the left side in the figure. Thereby, even if the width of the corner column 32 is reduced, the rotation axis c of the rotation unit 64 can be arranged at an appropriate position in consideration of the width of the corner column 32 and the size of the outer diameter d of the rotation unit 64. Therefore, it becomes possible to more reliably prevent the waterproof rubber 74 from being caught.

  Further, in the container 10 according to the embodiment of the present invention, as shown in FIGS. 3 and 4, the corner column 32 includes the outer member 34 and the inner member 50, and in the illustrated example, the three hinge mechanisms 62 include the outer member. 34 is provided. A lining plate 84 and an outer plate 88 are fixed to the outer member 34 so as to be installed on the indoor side of the end surface 12 of the container 10 and on the opposite side. At this time, the lining plate 84 is fixed to the lining plate receiving portion 36 of the outer member 34 to which the lining plate 84 is fixed in a state where the lining plate 84 is overlapped on the indoor side (upper side in FIG. 4), and the outer plate 88 is fixed. The outer plate 88 is fixed to the outer plate fixing portion 44 of the outer member 34 to be fixed in a state where the outer plate 88 is overlapped on the opposite side to the room (the lower side in FIG. 4). Further, the inner member 50 has a U-shaped cross section as shown in FIG. 4, and the tips of the portions 52A and 52B corresponding to the two U-shaped leg portions extend from the indoor side to the outer member. 34 is fixed. At this time, the inner member 50 is fixed so that the flat surface portion 54 located between the portions 52 </ b> A and 52 </ b> B corresponding to the two U-shaped leg portions is parallel to the wife surface 12 of the container 10. .

  Further, the inner side member 50 is fixed to the outer side member 34, and the indoor side surface 54a of the flat portion 54 described above is defined by the indoor side surface 84a of the lining plate 84 in a state fixed to the outer side member 34. The size of the plane P is as close as possible. In other words, in the portions 52A and 52B of the inner member 50, the interior side surface 54a of the flat portion 54 is defined by the interior side surface 84a of the lining plate 84 within a range that maintains the strength required for the corner post 32. It has a length that is as close as possible to the plane P. As a result, the corner column 32 of the container 10 according to the embodiment of the present invention has a smaller amount of protrusion to the indoor side than the corner column 100 of the conventional container shown in FIG. Both the width of the opening of the open door 20 provided on the side surface 18 and the capacity of the container 10 can be enlarged. Furthermore, while expanding the width of the opening portion of the side surface 18 of the container 10 as described above, as shown in FIG. 7, the rotation trajectory t at the tip of the fin portion 76 of the waterproof rubber 74 fixed to the open door 20 is a corner pillar. Since the positional relationship between the waterproof rubber 74 and the corner post 32 that crosses the side surface 56 of the 32 is maintained, the waterproof rubber 74 can be prevented from being caught.

  Further, as described above, the container 10 according to the embodiment of the present invention reduces the weight of the hinge mechanism 62 by reducing the diameter d of the rotating portion 64. As can be confirmed, in the present embodiment, the weight of the container 10 as a whole in which the hinge mechanisms 62 are provided at six locations can be reduced. Furthermore, although the container 10 according to the embodiment of the present invention includes the hinge mechanism 62 and the corner post 32 as described above, it affects the thickness and the like of the open door 20 provided on the side surfaces 16 and 18. It is not something to receive. For this reason, for example, by providing the side doors 16 and 18 with the open doors 20 with louvers as employed in conventional containers, it is possible to easily cope with ventilation of the container 10.

  In addition, the container 10 which concerns on embodiment of this invention is not limited to the Example mentioned above, For example, the structure different from the container 10 shown in FIG.1 and FIG.2 may be sufficient. That is, a container in which the opening door 20 is provided on the two surfaces of the side surfaces 16 and 18, a container in which the opening door 20 is provided on the two surfaces of the end surface 14 and the side surface 18, or the opening door 20 only in the side surface 16 It may be a container or the like provided with. Among these, in the case of a container in which the opening door 20 is provided on the two surfaces 16 and 18, the corner column 32 and the hinge mechanism 62 as shown in FIGS. You may have. Furthermore, the structure of the corner column 32 shown in FIGS. 3 to 7 is applied to only one corner column 32 of the two corner columns 32A and 32B depending on the presence or absence of the open door 20 on the side surfaces 16 and 18. You may have. Further, the configuration of the hinge mechanism 62 is not limited to the configuration shown in FIG. 5. For example, the rotating portion 64 has a columnar shape, and the upper and lower ends of the rotating portion 64 are the through holes 68 a of the pair of hinge lugs 68. The rotating portion 64 may rotate with respect to the pair of hinge lugs 68 by being inserted into the pair. Moreover, the fixing method which connects between each member is not limited to the welding or screwing mentioned above, A suitable fixing method can be used between each member.
