JP 2000-108774 A

  The seal member described in Patent Document 1 is made of a soft material and is not intended to improve the rigidity of the entire partition wall. However, for example, the entire partition wall may be lifted by an urging means such as a gas cylinder, and the rigidity of the partition wall is preferably high.

  Moreover, the sealing member of Patent Document 1 is fixed to the panel using a tape, and is not based on the assumption that the sealing member is attached or detached.

  Therefore, an object of the present invention is to provide an end protection structure that can increase the rigidity of the entire partition wall and that can be attached and detached, and a partition wall having the end protection structure.

(1) In order to achieve the above object, an end protection structure according to the present invention is an end protection structure used for a panel made of a synthetic resin material that partitions the inside of a vehicle cargo box, and is provided at an end of the panel. A channel member attached to the channel member, the channel member including two support portions for sandwiching the panel; and a substrate portion connecting the two support portions; and a cover member attached to the channel member. And both end portions of the cover material are attached to the two support portions, and further includes a cushion material disposed inside the cover material, and both end portions of the cover material are It is attached to the two support parts by being sandwiched between one support part and the panel.

  In this configuration, the channel member includes two support portions and a substrate portion. That is, the channel member is formed so as to have a U-shaped portion (groove portion) when the front surface is viewed along the longitudinal direction. Therefore, the rigidity of the whole partition wall becomes high by attaching a channel member to a panel. Moreover, since the channel member has such a shape, the channel member can be attached to and detached from the panel. As described above, an end protection structure that can increase the rigidity of the entire partition wall and that can be detached is obtained.

  Note that the end protection structure may be attached over the entire periphery of the panel, or may be attached to a part of the periphery of the panel (for example, only the bottom and side portions). In the end protection structure, the channel member may be exposed, or the channel member may be covered with a cover material.

  The material of the channel member is preferably light and hard, and for example, hard plastic (general thermosetting resin, styrene resin, acrylic resin, polypropylene, polyvinyl chloride, etc.), metal, and FRP can be used.

  When using the edge protection structure with the channel member exposed, (i) the edge of the panel is protected by using synthetic resin as the material of the channel member. Further, (ii) since the partition wall becomes slippery, the partition wall can be easily moved.

Further, by using a flexible material as a cushion material inside the cover material, even if there is irregularity in the packing box, the space between the inner surface of the packing box and the partition wall is surely sealed. Further, the channel member functions as a member for attaching the cushion material to the panel.

In addition, as a material of a cushion material, flexible materials, such as foaming urethane (urethane sponge), foaming polyethylene, foaming EVA, are mentioned. Moreover, you may use an air tube as a cushioning material. Further, the channel member only needs to be formed so as to have a U-shaped portion (groove portion) when the front surface is seen along the longitudinal direction, and the channel member has its front surface along the longitudinal direction. The shape when viewed may be U-shaped, H-shaped, or the like.
Further, the cover material can be attached to the channel member by a simple method of winding the cover material between the panel and the channel member. In this case, regarding the coupling of the channel member and the cover material, other coupling means such as a hook-and-loop fastener, a double-sided tape, and screwing may be used, or such a coupling means may not be used. Good.
In addition, as a material of the cover material, a knit cloth, a tarpaulin made of polyvinyl chloride, a polyurethane film, or the like may be used alone or in combination. If a knit cloth that can be expanded and contracted in the vertical direction and the horizontal direction is used as the cover material, the flexibility of the end protection structure is secured, and the space between the inner surface of the packing box and the partition wall is reliably sealed.

( 2 ) Moreover, the edge part protection structure which concerns on this invention WHEREIN: The said cushion material has a 1st cushion material and a 2nd cushion material, and the said 1st cushion material is harder than a said 2nd cushion material. The first cushion material and the second cushion material may be arranged in this order from the side closer to the panel.

  In this configuration, since the cushion material has two kinds of hardness, the end protection structure has appropriate flexibility and appropriate rigidity. Therefore, according to this configuration, a more reliable sealing function can be obtained.

  Note that “the first cushion material is harder than the second cushion material” means that the first cushion material is less likely to be deformed than the second cushion material when the same force is applied. .

  As a combination of the first cushion material and the second cushion material, for example, the first cushion material: foamed polyethylene, the second cushion material: foamed urethane (urethane sponge), or the first cushion material: foamed EVA, second cushion material : A combination such as urethane foam may be used.

( 3 ) Moreover, in order to achieve the said objective, the partition wall which concerns on this invention has the panel which consists of a synthetic resin material which partitions off the inside of a vehicle cargo box, and said one edge part protection structure.

  According to this structure, the rigidity of the whole partition wall can be made high. Further, the end protection structure can be detached.

( 4 ) Moreover, in order to achieve the said objective, the partition wall which concerns on this invention has two panels which consist of a synthetic resin material which partitions off the inside of a vehicle cargo box, and an edge part protection structure, The end protection structure includes two channel members attached to the end portions of the two panels and two cover members attached to the two channel members, and each of the channel members includes the panel. Two support portions for sandwiching and a substrate portion for connecting the two support portions are provided, and the two cover members are detachably connected at a boundary portion between the two panels.

  According to this structure, the rigidity of the whole partition wall can be made high. Further, the end protection structure can be detached. Further, in this configuration, the two panels can be integrated or separated by connecting or separating the two cover materials.

  As the partition wall is moved, the end protection structure is worn by contact between the two cover members or by contact between the inner surface of the cargo box and the end protection structure. Therefore, by making the two channel members and the two cover members detachable, maintenance such as replacement and repair of the end protection structure (cover member and channel member) is facilitated.

  For example, by using a hook-and-loop fastener and a wire fastener for the two cover members, the two cover members can be easily attached and detached.

( 5 ) Moreover, in order to achieve the said objective, the partition wall which concerns on this invention has two panels which consist of a synthetic resin material which partitions off the inside of a vehicle cargo box, and an edge part protection structure, The end protection structure includes two channel members attached to the end portions of the two panels and a cover material, each of the channel members having two support portions for sandwiching the panel, A substrate portion connecting the two support portions, and the cover member is attached to the two channel members at a boundary portion on one surface side of the two panels.

  According to this structure, the rigidity of the whole partition wall can be made high. Further, the end protection structure can be detached. Further, in this configuration, two panels can be integrated with a simple configuration. Further, the cover material functions as a hinge member for the two panels.

The end protection structure 30 includes a resin channel 33, a urethane sponge 31, a foamed polyethylene 32, and a knit cloth 30t.

  The resin channel (channel member) 33 is formed of a synthetic resin material (polyvinyl chloride), and includes a substrate portion 33b and two support portions 33c. The two support portions 33c are for sandwiching the heat insulating panel 10, and the two support portions 33c are connected by the substrate portion 33b. The resin channel 33 is attached to the end of the heat insulating panel 10. The material of the channel member may be hard plastic (general thermosetting resin, styrene resin, acrylic resin, polypropylene, etc.), metal, or FRP.

  The urethane sponge 31 and the foamed polyethylene 32 are cushion materials arranged inside the knitted cloth 30t. The foamed polyethylene (first cushion material) 32 is affixed to the resin channel 33 using a double-sided tape or the like. The urethane sponge (second cushion material) 31 is affixed to the foamed polyethylene 32 using a double-sided tape or the like. The foamed polyethylene 32 is harder than the urethane sponge 31.

Panel reinforcing member 11a and two panel reinforcing members 11b) are attached (see FIG. 2). In addition, "the height direction of the heat insulation panel 10 in a state where the interior 2 is partitioned by the heat insulation panel 10" is a vertical direction in a state where the interior 2 is partitioned by the heat insulation panel 10.

  As shown in FIGS. 2 and 3, each of the panel reinforcing members 11 (panel reinforcing member 11 a and panel reinforcing member 11 b) of the present embodiment is substantially the same as the heat insulating panel 10 along the vertical direction of the heat insulating panel 10. It is a long reinforcing material attached to the surface of the heat insulating panel 10 from the upper end (upper part) to the lower end (lower part). Further, the longitudinal direction of the panel reinforcing member 11 is the vertical direction of FIG. Moreover, the shape of the cross section orthogonal to the longitudinal direction of the panel reinforcing member 11 (11a, 11b) is a shape having ridges (protruding portions; raised portions) on both sides in the width direction, whereby the panel reinforcing member The section modulus of 11 is increased and the strength is improved (see FIG. 3). Moreover, the center part pinched | interposed into the peak part of the panel reinforcement member 11 is a flat shape so that the screw, rivet, etc. for fixing to the heat insulation panel 10 can be arrange | positioned. That is, the central portion of the panel reinforcing member 11 is formed in a groove shape. Each panel reinforcing member 11 is an extruded material of an aluminum alloy.

The suspension member 18 is supported by the left rail 19a and the right rail 19b via the wheel 20 (see FIGS. 1 and 2). Further, as described above, the left rail 19a and the right rail 19b are provided along the upper ends of the side walls 4 on both sides (both sides in the width direction) of the interior 2. Thereby, the suspending member 18 which suspended and supported the heat insulation panel 10 can be smoothly moved in the store | warehouse | chamber 2, and, as a result, the heat insulation panel 10 suspended and supported by the suspending member 18 is stored in the store 2 Can be moved smoothly. Therefore, the position of the partition can be easily changed.

  The suspension member 18 includes components arranged along the width direction (left-right direction; direction orthogonal to the front-rear direction) of the interior 2 (see FIG. 3). Hereinafter, the constituent members arranged along the width direction are referred to as “width direction constituent members”.

(Biasing member)
The partition device 3 includes an urging member 13. The urging member 13 urges the heat insulating panel 10 via the panel reinforcing member 11 so that the heat insulating panel 10 rotates (rotates) in the vertical direction.

In the present embodiment, the partition wall in the interior 2 includes an end protection structure, a heat insulating panel 10, a plurality of panel reinforcing members 11, and two hinge members 12. And this partition wall is attached to the inside 2 so that it can rotate, and is urged | biased by the biasing member 13 in the rotation direction (direction of rotation of the heat insulation panel 10). . In addition, the partition wall may be comprised only from the heat insulation panel and the edge part protection structure (a panel reinforcement member and a hinge member may not be included in a partition wall).

(Panel operation: during storage operation)
Next, operation | movement of the heat insulation panel 10 of the partition device 3 is demonstrated. The state of FIGS. 1 and 6 shows a state in which the interior 2 is partitioned by the heat insulating panel 10. Initially, operation which stores the heat insulation panel 10 in the ceiling 8 part of the store | chamber 2 from this state is demonstrated.

  First, the operator removes the two lashing belts 7 from the connecting portions 6 of the four lashing rails 5.

  Next, with the panel rotation shaft 25 loosely inserted into the hinge member 12 as a fulcrum, the heat insulation panel 10 is rotated toward the ceiling 8 and in the direction where the urging member 13 is located. In the case of FIG. 1, the operation is performed so as to pull up to the near side. The movement of the heat insulation panel 10 at this time is shown in FIG.

  A biasing member 13 is attached to the heat insulating panel 10 (via the panel reinforcing member 11a and the hinge member 12). Therefore, when the thermal insulation panel 10 is lifted (rotated) by a certain rotation angle, the urging force by the urging member 13 is then stored in the direction in which the thermal insulation panel 10 is stored in the ceiling 8 (the rotation of the panel). Direction). As a result, the urging force of the urging member 13 assists the operator's pulling work, so that the force required for the pulling work is reduced. The “panel rotation direction” includes not only the pulling direction but also the operation (described later) for partitioning the interior 2 from the state in which the heat insulation panel 10 is stored in the ceiling 8 with the heat insulation panel 10. The direction in which the lens rotates (the pulling-down direction) is also included.

  When the heat insulation panel 10 is pulled up to a position that is substantially parallel to the surface of the ceiling 8, the latch 16 attached to the heat insulation panel 10 (via the latch bracket 22) is attached to the suspension member 18 as shown in FIG. The latch 16 and the hook 24 are engaged with each other (ie, the connection of the latch 16 and the hook 24 is completed). In the state of FIG. 8, since the latch 16 and the hook 24 are engaged, even if the operator removes his / her hand from the heat insulation panel 10, the heat insulation panel 10 is maintained in a state parallel to the ceiling 8 surface. It doesn't hang down.

  Next, the heat insulation panel 10 is fixed to the ceiling 8 using the panel fixing belt 23 shown in FIG. Thus, the operation for storing the heat insulating panel 10 in the ceiling 8 is completed.

(Panel operation: during partition operation)
Next, an operation of pulling down the heat insulation panel 10 from the state in which the heat insulation panel 10 is stored in the ceiling 8 and partitioning the interior 2 with the heat insulation panel 10 will be described.

  First, the operator removes the panel fixing belt 23 fixed to the ceiling 8 from the ceiling 8.

  Next, the end of the latch release belt 17 shown in FIG. 2 is pulled to release the engagement between the latch 16 and the hook 24. Thereby, although the heat insulation panel 10 tends to hang down by its own weight, since the heat insulation panel 10 is urged | biased by the urging | biasing member 13 at the ceiling 8 side, so that the heat insulation panel 10 may fall from the ceiling 8, It does not droop drastically.

  Next, the heat insulation panel 10 is rotated in the direction of the floor 9 position with the panel rotation shaft 25 loosely inserted into the hinge member 12 as a fulcrum. The movement of the heat insulation panel 10 at this time is shown in FIG. And after rotating the heat insulation panel 10 to a predetermined position, the two lashing belts 7 are connected with the connection part 6 of the four lashing rails 5. FIG. Thus, the operation of partitioning the interior 2 with the heat insulating panel 10 is completed.

(effect)
Next, effects of the end protection structure 30 and the partition wall according to the present embodiment will be described. The end protection structure 30 is used for the heat insulating panel 10 made of a synthetic resin material that partitions the inside of the vehicle cargo box, and has a resin channel (channel member) 33 attached to the end of the heat insulating panel 10. The channel 33 includes two support portions 33c for sandwiching the heat insulating panel 10, and a substrate portion 33b for connecting the two support portions 33c.

  In this configuration, the resin channel 33 includes two support portions 33c and a substrate portion 33b. That is, the resin channel 33 is formed to be U-shaped when the front surface is viewed along the longitudinal direction. Therefore, the rigidity of the whole partition wall becomes high by attaching the resin channel 33 to the heat insulation panel 10. Further, since the resin channel 33 has such a shape, the resin channel 33 can be attached to and detached from the heat insulating panel 10. As described above, an end protection structure that can increase the rigidity of the entire partition wall and that can be detached is obtained.

  The end protection structure 30 further includes a knit cloth (cover material) 30t attached to the resin channel 33, and both ends of the knit cloth 30t are attached to the two support portions 33c. It further has a cushion material (urethane sponge 31 and foamed polyethylene 32) disposed inside the knit cloth 30t.

  In this configuration, by using a flexible material as a cushioning material inside the knit cloth 30t, even if there are irregularities in the packing box, the space between the inner surface of the packing box and the partition wall is reliably sealed. . The resin channel 33 functions as a member for attaching the cushion material to the heat insulating panel 10. The resin channel 33 serves as a base (base) for the cushion material, and the knit cloth 30 t and the cushion material are attached to the resin channel 33.

  Moreover, in the edge part protection structure 30, a cushion material has a 1st cushion material (foamed polyethylene 32) and a 2nd cushion material (urethane sponge 31), and a 1st cushion material is rather than a 2nd cushion material. The first cushion material and the second cushion material are arranged in this order from the side closer to the heat insulation panel 10.

  In this configuration, since the cushion material has two kinds of hardness, the end protection structure has appropriate flexibility and appropriate rigidity. Therefore, according to this configuration, a more reliable sealing function can be obtained.

  In the end protection structure 30, both end portions of the knit cloth 30 t are attached to the two support portions 33 c by being sandwiched between the two support portions 33 c and the heat insulating panel 10.

  According to this configuration, the knit cloth 30 t can be attached to the resin channel 33 by a simple method of winding the knit cloth 30 t between the heat insulating panel 10 and the resin channel 33.

  In addition, the partition wall according to the present embodiment includes a heat insulating panel 10 made of a synthetic resin material and an end protection structure 30 that partitions the inside of the vehicle cargo box. According to this structure, the rigidity of the whole partition wall can be made high. Further, the end protection structure can be detached.

  Next, FIG. 9 will be described. FIG. 9 is a side view for explaining the positional relationship between the biasing member 13 and the hinge member 12 when the heat insulation panel 10 is rotated. As shown in FIG. 9, in a state where the interior 2 is partitioned by the heat insulating panel 10 (panel use state), the urging direction X by the urging member 13 is lower than the rotation center C of the heat insulating panel 10. It becomes the direction to go. On the other hand, in the state where the heat insulation panel 10 is stored in the ceiling 8 part of the interior 2, the urging direction Y by the urging member 13 is a direction upward from the rotation center C. Thereby, not only when the heat insulation panel 10 is stored in the ceiling 8 part of the interior 2 but also when the heat insulation panel 10 is rotated to partition the interior 2, the urging force by the urging member 13 can be used. Therefore, the partitioning operation using the heat insulating panel 10 and the fixing operation of the heat insulating panel 10 to the side walls 4 on both sides of the interior 2 in that state can be easily and reliably performed.

(First modification)
A first modification of the above embodiment will be described with reference to FIG. FIG. 12 is a diagram illustrating a first modification of the heat insulating panel 10. As shown in FIG. 12, the heat insulating panel may be divided into left and right parts, each including a heat insulating panel 10 a and a heat insulating panel 10 b. Thereby, a heat insulation panel can be stored in the ceiling 8 part with a smaller operation force.

  In the above embodiment, the suspension member 18 has a frame shape, but the shape of the suspension member 118 in this modification is different from that of the suspension member 18 described above. Specifically, the suspension member 118 has two width direction constituent members 118w and two front and rear direction constituent members 118h. The front-rear direction constituent member 118 h is a constituent member disposed along the front-rear direction of the interior 2. And the two front-back direction structural members 118h have connected the intermediate position of the two width direction structural members 118w (refer Fig.13 (a)). In addition, unlike the suspension member 18, the suspension member 118 is not provided with a component member that connects the ends of the two width direction component members 118w.

  Further, four clamp members 118c are provided at both end portions of the rear side width direction constituting member 118w. Each clamp member 118c is attached to the width direction component member 118w via the clamp bracket 118b. The suspension member may be configured in this way.

FIG. 14 is a front view of the partition wall according to the third modification. FIG. 15 is a rear view of the partition wall according to the third modification. FIGS. 16A and 16B are cross-sectional views for explaining an end protection structure according to a third modification. FIG. 16A is a cross-sectional view taken along the line DD in FIG. 14, and FIG. . Further, in FIGS. 14 to 16, the portions denoted by reference numerals 210, 210g, 210h, 211c, 216, 222, 231, 232, 233, 233b, and 233c are denoted by reference numerals 10, 10g, 10h, 11c, 16, 22, 31, 32, 33, 33b, and 33c are equivalent to the parts.

  In the above embodiment, the plurality of panel reinforcing members 11 are attached only to one surface of the heat insulating panel 10. On the other hand, in this modified example, a plurality of panel reinforcing members 211 are attached to both surfaces of the heat insulating panel 210. Specifically, four panel reinforcing members 211 (four panel reinforcing members 211a) are arranged on one surface (front surface) 210s of the heat insulating panel 210 (see FIG. 14), and on the other surface (back surface) 210r. Also, four panel reinforcing members 211 (two panel reinforcing members 211d and two panel reinforcing members 211e) are arranged (see FIG. 15). The panel reinforcing member may be arranged in this way with respect to the heat insulating panel.

  Further, around the heat insulating panel 210, an end protection structure 230b, an end protection structure 230c, and an end protection structure 230d are attached (see FIGS. 14 and 15). The end protection structure 230 c shown in FIG. 16A is attached to the bottom of the heat insulation panel 210. The end protection structure 230c includes a resin channel 233, a foamed polyethylene 232, and a knit cloth 230t. Both end portions of the knitted cloth 230t are sandwiched between the two support portions 233c and the heat insulating panel 210, whereby both end portions of the knitted cloth 230t are attached to the resin channel 233.

  Further, in the end protection structure 230 c, the interval between the two support portions 233 c of the resin channel 233 is set to be equal to or less than the thickness of the heat insulation panel 210 before being attached to the heat insulation panel 210. . For this reason, no screws or the like are used in the end protection structure 230 c, but the resin channel 233 attached to the heat insulation panel 210 is difficult to come off from the heat insulation panel 210. Further, the knit cloth 230 t is also difficult to come off between the resin channel 233 and the heat insulating panel 210.

  End protection structure 230d shown in FIG. 16B is attached to the upper end of heat insulation panel 210. The structure of the end protection structure 230d is the same as that of the end protection structure 30 in FIG. Note that the structure of the end protection structure 230b is the same as that of the end protection structure 230d, and the BB cross-sectional view of FIG. 14 is represented in the same way as FIG. Omitted.

  In the present modification, the knit cloth 230t is sandwiched between the resin channel 233 and the heat insulating panel 210, so that the knit cloth 230t can be attached to the resin channel 233 without screwing.

(Fourth modification)
Next, with reference to FIGS. 17 and 18, a fourth modification of the above embodiment will be described with a focus on differences from the above embodiment. In addition, about the part similar to said embodiment, the same code | symbol is attached | subjected to a figure and the description is abbreviate | omitted.

In this manner, the hinge member 912 connects the suspension member 918 and the heat insulation panel 10. Moreover, each hinge member 912 is attached to the panel reinforcement member 911a (or heat insulation panel 10) in the state which the heat insulation panel 10 can rotate. Further, in the partition device 903, a panel reinforcing member 911 d is attached to the heat insulating panel 10 along the width direction. The partition device may be configured in this way.

  In this modification, all the hinge members 912 may be attached to the panel reinforcing member 911a, or all the hinge members 912 may be directly attached to the heat insulating panel 10.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention.

  When the panel is divided, it is not limited to the left and right divisions. For example, the panel may be divided into three in the left and right direction, or may be divided into two in the vertical direction. Moreover, as a heat insulation panel used for this invention, various things, such as what was described in Unexamined-Japanese-Patent No. 2000-108774 and Unexamined-Japanese-Patent No. 2004-144470, can be utilized, for example.

  Further, the end protection structure may be composed only of a resin channel and urethane sponge (or foamed polyethylene). In this case, the urethane sponge (or foamed polyethylene) is attached to the resin channel with a double-sided tape or the like.

  In addition, the resin channel is not limited to one having a uniform cross section at all positions in the longitudinal direction, and may have a shape as shown in FIG. That is, the channel member only needs to be configured such that each support portion 33C and the substrate portion 33B form a right angle. As a result, the channel member 33W in FIG. 26 has a U-shape when viewed from the front along the longitudinal direction (see the arrow L direction in the figure).

  Moreover, in the partition wall of said embodiment, the biasing member 13 is attached to the heat insulation panel 10 via the panel reinforcement member 11a. However, the configuration of the partition wall is not limited to this, and the urging member may be attached to the heat insulating panel at a position different from the panel reinforcing member in the partition wall.
