Description

[Technical Field]

[0001] The present invention relates to a carrier that enables a wide variety of items to be carried on the back, and more particularly to a so-called backpack carrier. [Background technology]

[0002] Patent Documents 1 to 3 disclose carriers capable of safely and stably carrying an object (such as an emergency medical device) to be carried. These carriers are equipped with a pair of shoulder belts that are placed over the shoulders of the carrier, a back support portion to which the pair of shoulder belts are attached and which contacts the carrier's back, and a support portion that supports the object from below. The carrier places the object on the support portion of the carrier and secures it with a belt or the like, and then puts the pair of shoulder belts over both shoulders and carries the object on their back, thereby enabling the object to be carried stably. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 06-070624 [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-104377 [Patent Document 3] Patent Publication No. 2021-178084 Summary of the Invention [Problem to be solved by the invention]

[0004] These carriers have a frame that is bent into a substantially L-shape in side view in order to integrally form the back support portion and the support portion. Generally, this L-shaped frame is made of a highly rigid metal to support the transported item. Therefore, conventional carriers increase the burden during transport due to the weight of the metal. This has led to the problem of the carrier becoming easily fatigued, especially when transporting the transported item for a long period of time. The present invention has been made in view of such problems, and has as its object to provide a carrier that can reduce the burden during transportation. [Means for solving the problem]

[0005] The object of the present invention is to A transport device for transporting an object, A pair of shoulder straps that are worn on both shoulders of the carrier, a substantially plate-shaped back support plate portion to which the pair of left and right shoulder belts are attached and whose front surface abuts against the back of the carrier; A substantially plate-shaped bottom plate portion is arranged to extend substantially rearward from the vicinity of the lower end of the back support plate portion and supports the transported object from below; a pair of generally plate-shaped left and right side plate portions that stand upright near the left and right ends of the bottom plate portion and press the transported object from both the left and right sides; a first connecting means for connecting a lower portion of the back support plate portion and a front portion of the bottom plate portion; second connecting means for connecting the bottom plate portion to lower portions of the pair of left and right side plate portions; a first belt member attached to the back support plate portion and configured to be able to be wound around the rear side while passing through the left and right sides of the transported object supported by the bottom plate portion and engaging with the pair of left and right side plate portions; The object is achieved by a carrier in which the back support plate portion, the bottom plate portion, and the pair of left and right side plate portions are each formed from a resin material.

[0006] According to the present invention, the back support plate that contacts the carrier's back, the bottom plate that supports the transported item from below, and the pair of left and right side plates that hold the transported item from both sides are all made of resin material, which makes the carrier significantly lighter than if it were made of metal, reducing the burden on the carrier during transport and, as a result, reducing fatigue on the carrier.

[0007] Furthermore, according to the present invention, the first belt member attached to the back support plate portion is configured to engage with the left and right side plate portions, and to be able to pass around the left and right sides of the transported item supported by the bottom plate portion and wrap around the rear side.

[0008] In a preferred embodiment of the present invention, The pair of left and right side plate portions each have an insertion portion formed therein through which the first belt member can be inserted and engaged in a substantially front-rear direction, The insertion portion has a first insertion portion and a second insertion portion that are positioned differently in the vertical direction, and is configured so that the first belt member can be inserted and engaged twice through the pair of left and right side plate portions.

[0009] According to this preferred embodiment of the present invention, each of the left and right side plate portions has an insertion portion formed therein through which the first belt member is inserted twice, and in each insertion portion, the first insertion point (first insertion portion) and the second insertion point (second insertion portion) are located in different vertical positions, so that each of the left and right side plate portions can be firmly held in an upright position (= erect position, standing position), thereby effectively preventing the left and right side plate portions from being pushed sideways by the transported goods.

[0010] In a further preferred embodiment of the present invention, The second connecting means includes a distance adjustment mechanism that can adjust the distance between the bottom plate portion and the pair of left and right side plate portions.

[0011] According to this preferred embodiment of the present invention, the distance between the bottom plate and the pair of left and right side plate portions can be adjusted, so that the carrier can change the left-right position of each side plate portion to accommodate items of various left-right dimensions.

[0012] In addition, the carrier can widen the gap between the bottom plate and the pair of left and right side plates, allowing the back plate, bottom plate, and pair of left and right side plates to be folded compactly so that they overlap each other.

[0013] In a further preferred embodiment of the present invention, The first connecting means includes a distance adjustment mechanism that adjusts the distance between the bottom plate portion and the back support plate portion, The first belt member is provided with a first length adjustment mechanism for adjusting the length thereof.

[0014] According to this preferred embodiment of the present invention, the distance between the bottom plate portion and the back support plate portion can be adjusted, and the first belt member is configured to be able to be inserted in approximately the front-to-back direction through the insertion portions formed in each of the left and right side plate portions.Therefore, the carrier can change the front-to-back position of the bottom plate portion to match the position of the center of gravity of the item being transported in the front-to-back direction, slide the pair of left and right side plate portions back and forth along the first belt member, and further adjust the length of the first belt member, thereby accommodating items with various front-to-back dimensions (= depth dimensions).

[0015] In a further preferred embodiment of the present invention, A second belt member is provided which passes above and behind the article supported by the bottom plate portion and is configured to be able to connect the upper part of the back support plate portion and the rear part of the bottom plate portion, The second belt member is provided with a second length adjustment mechanism for adjusting the length thereof.

[0016] According to this preferred embodiment of the present invention, the second belt member, which passes above and behind the transported item and connects the upper part of the back support plate portion and the rear part of the bottom plate portion, is equipped with a second length adjustment mechanism, so that the second belt member can be shortened (=squeezed) after the transporter places the transported item on the bottom plate portion, preventing the transported item from tilting backward.

[0017] In a further preferred embodiment of the present invention, The pair of left and right side plate portions are formed so that the upper edges of the rear portions are inclined downward toward the rear.

[0018] According to this preferred embodiment of the present invention, the rear upper edges of the pair of left and right side panels are formed to slope downward toward the rear, so that when transporting an object with a lid on top, such as a general insulated container (cooler box), the rear upper edges of the pair of left and right side panels are less likely to interfere with (i.e., come into contact with) the lid when the lid is opened or closed, thereby enabling the lid of the object to be opened and closed smoothly. [Effects of the Invention]

[0019] According to the present invention, a carrier that can reduce the burden during transportation can be provided. [Brief explanation of the drawings]

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0022] Fig. 1 is a schematic perspective view of a carrier 1 according to a first embodiment of the present invention, and Fig. 2 is a schematic perspective view showing a state in which an object C is supported by the carrier 1 shown in Fig. 1. Fig. 3 is an exploded view of the carrier 1 shown in Fig. 1. Fig. 3 shows the front surface of the back support plate 3, the outer surfaces of a pair of side plates 5b, and the underside of the bottom plate 5a, which will be described in detail later.

[0023] The carrier 1 includes a plate-shaped back support plate 3 whose front surface contacts the carrier's back, a pair of shoulder straps 2 attached to the back support plate 3, a support portion 5 connected to the back support plate 3 and supporting the object C, a first belt member 6 that secures the object C while supported by the support portion 5, and a second belt member 7 that prevents the object C from tilting backward. Hereinafter, the back of the carrier relative to the back support plate 3 will be referred to as the "front," and the side of the object C will be referred to as the "rear." Furthermore, the left side when facing forward will be referred to as the "left," and the opposite side will be referred to as the "right." Note that Figures 1 and 2 show the carrier 1 as viewed from above and rear-right. In Figure 1, the second belt member 7 is drawn with a two-dot chain line to clearly show the support portion 5, the first belt member 6, and other components located behind the second belt member 7 are also drawn without obscuring them.

[0024] The carrier can carry the object C by putting the pair of shoulder straps 2 on both shoulders and walking with the carrier 1 on their back, just like a regular backpack. The object C can be a variety of objects such as an insulated container, cardboard box, styrofoam box, rack, etc., but the following explanation will be given assuming that the object C is an insulated container.

[0025] The back support plate 3 is formed from a flexible resin (more specifically, polyethylene) plate, and its edges are trimmed with nylon material. In addition, the upper part of the back support plate 3 is also covered with nylon material. Note that in addition to polyethylene, other resins such as polypropylene can also be used as the material for the back support plate 3. A pad member made of a cushion material that is elastic and flexible is provided on the front of the back support plate 3, which comes into contact with the carrier's back, so that the carrier's back is less likely to hurt even when carrying an angular-shaped object C.

[0026] The support portion 5 includes a substantially plate-shaped bottom plate 5a that supports the load C from below, and a pair of substantially plate-shaped side plates 5b that are connected to the bottom plate 5a and press down on the load C from both sides. The support portion 5 is configured symmetrically (see FIG. 4). The bottom plate 5a and the pair of side plates 5b are each formed of a resin (more specifically, polyethylene) plate, with their edges trimmed with nylon. The bottom plate 5a and the pair of side plates 5b can be made of any resin material, including polyethylene and other resins such as polypropylene. By forming the support portion 5 that supports the load C and the back support plate 3 from a resin material, the weight of the carrier 1 can be significantly reduced compared to the conventional carriers described in Patent Documents 1 to 3 that are made of metal or the like.

[0027] The bottom plate portion 5a is connected to the lower end of the back support plate portion 3 by hook-and-loop fasteners 8a, 8b (see Figures 3 and 5), which will be described in detail later, and is positioned so as to extend approximately rearward from near the lower end of the back support plate portion 3.

[0028] The pair of left and right side plates 5b are arranged to stand (i.e., stand upright) near both left and right ends of the bottom plate 5a (more specifically, beside the left and right ends). Each side plate 5b includes a main side plate 5b1 that holds the transported item C from the side and a secondary side plate 5b2 sewn to the outer surface (i.e., the outer side surface in the left-right direction) of the main side plate 5b1. The upper and lower portions of the secondary side plate 5b2 are sewn to the main side plate 5b1 at perforations indicated by dashed lines 5b5 in FIG. 1, while the approximate center of the secondary side plate 5b2 in the up-down direction is not sewn to the main side plate 5b1. Therefore, an insertion portion 5b3 formed as a gap is formed between the approximate center of the secondary side plate 5b2 in the up-down direction and a portion of the main side plate 5b1 located to the side thereof. The first belt member 6 is inserted into the left and right insertion portions 5b3 in the approximately front-rear direction, thereby engaging (sliding) the side plate 5b in the front-rear direction. That is, the insertion portion 5b3 is configured to allow the first belt member 6 to be inserted therethrough. As a result, the pair of left and right side plate portions 5b are supported by the first belt member 6 (more specifically, the support belt 6a described later), and therefore the pair of left and right side plate portions 5b can be prevented from being pushed by the transported object C during transport and falling to the left and right.

[0029] One end of a connecting belt 9a for connecting to the bottom plate 5a is fixed to the lower part of the main side plate 5b1 of each of the left and right side plate portions 5b. The other free end of this connecting belt 9a is passed through D-shaped pipes 9b (9b1 to 9b4, see Figures 3 and 4) provided on the underside of the bottom plate 5a, two on each side, thereby connecting the pair of left and right side plate portions 5b and the bottom plate portion 5a. Note that Figure 3 shows the connecting belts 9a detached from the D-shaped pipes 9b.

[0030] 3, the first belt member 6 includes a pair of left and right support belts 6a that support the pair of left and right side plate portions 5b in an upright position, a left belt 6b connected to the left support belt 6a, and a right belt 6c connected to the right support belt 6a. One end of the left belt 6b and the right belt 6c are each connected to approximately the center of the support belt 6a in the longitudinal direction via a belt loop 6d (a so-called single loop).

[0031] The left belt 6b has a female buckle 6b1 configured as a side release buckle at the other end, and the right belt 6c has a male buckle 6c1 at the other end that can be connected to the female buckle 6b1. The male buckle 6c1 has an adjuster mechanism (corresponding to the "first length adjustment mechanism") that adjusts the length of the right belt 6c.

[0032] Therefore, with the article C placed on the bottom plate 5a, the left support belt 6a and the left belt 6b are wrapped around the left side of the article C and around the rear side, and the right support belt 6a and the right belt 6c are wrapped around the right side of the article C and around the rear side. After the buckles 6b1 and 6c1 are connected to each other at the rear side of the article C, the length of the right belt 6c is shortened (adjusted to be shorter) using the male buckle 6c1, thereby firmly securing the article C to the support portion 5. Therefore, the article C can be stably transported while reducing the weight of the carrier 1. Note that in this embodiment, when the first belt member 6 is wrapped around the article C in this manner, the buckles 6b1 and 6c1 are configured to be located behind the article C. However, the buckles 6b1 and 6c1 may be configured to be connected at a position closer to the back support plate 3.

[0033] Meanwhile, the left and right support belts 6a are configured similarly and each pass through the insertion portions 5b3 of the left and right side plates 5b twice. More specifically, the other end of the left support belt 6a, one end of which is attached to the upper left part of the back support plate 3, passes through the insertion portion 5b3 of the left side plate 5b to the front, then passes through the left belt loop 6d and is folded back to the rear. It then passes through the same insertion portion 5b3 again to the rear and is attached to the lower left part of the back support plate 3. Similarly, the other end of the right support belt 6a, one end of which is attached to the upper right part of the back support plate 3, passes through the insertion portion 5b3 of the right side plate 5b to the front, then passes through the right belt loop 6d and is folded back to the rear. It then passes through the same insertion portion 5b3 again to the rear and is attached to the lower right part of the back support plate 3.

[0034] Here, when each of the left and right support belts 6a is folded back at the belt loops 6d, it is folded back at an angle so that the left and right sides of the belt do not overlap when viewed from the side (see Figures 1 to 5, etc.). Therefore, the first insertion point I1 (corresponding to the "first insertion point") of each of the left and right support belts 6a into the insertion portion 5b3 (= before folding back) is located above the second insertion point I2 (corresponding to the "second insertion point") (= after folding back). That is, in each of the left and right insertion portions 5b3, the first insertion point I1 and the second insertion point I2 of the support belt 6a are located at different vertical positions. This allows the left and right side plate portions 5b to be firmly held in a substantially upright position, effectively preventing the left and right side plate portions 5b from tipping outward in the left-right direction due to being pushed by the transported object C.

[0035] The second belt member 7 includes an upper belt 7a, one end of which is attached to the upper part of the backrest plate 3, and a lower belt 7b, one end of which is attached to the front part of the bottom plate 5a. The upper belt 7a includes a male buckle 7a1, which is a side release buckle, at the other end, and the lower belt 7b includes a female buckle 7b1, which can be connected to the male buckle 7a1, at the other end. The male buckle 7a1 and the female buckle 7b1 are connected to each other, thereby connecting the upper part of the backrest plate 3 and the rear part of the bottom plate 5a via the second belt member 7. In addition, the male buckle 7a1 includes an adjuster mechanism (corresponding to a "second length adjustment mechanism") that adjusts the length of the upper belt 7a. Therefore, the carrier connects the male buckle 7a1 of the upper belt 7a, which is passed over the object C, to the female buckle 7b1 of the lower belt 7b, which is passed behind the object C, and then tightens (shortens) the upper belt 7a using the male buckle 7a1, thereby preventing the object C from tilting backward and keeping it approximately horizontal. When the object C tilts backward, a gap is created between the upper back surface of the back support plate 3 and the object C.

[0036] Fig. 4 is a schematic rear view showing only the support part 5 shown in Fig. 1, Fig. 4(a) is a schematic rear view showing a state in which the gap between the bottom plate part 5a and the pair of left and right side plate parts 5b is relatively narrow, and Fig. 4(b) is a schematic rear view showing a state in which the gap between the bottom plate part 5a and the pair of left and right side plate parts 5b is relatively wide. Note that in Fig. 4, the lower belt 7b is omitted for the sake of convenience of explanation.

[0037] As shown in FIGS. 3 and 4, two D-shaped pipes 9b1 and 9b2 are provided on the left side of the underside of the bottom plate 5a, and two D-shaped pipes 9b3 and 9b4 are provided on the right side. The other end of the connecting belt 9a, one end of which is fixed to the left side plate 5b, is threaded through the two left-hand D-shaped pipes 9b1 and 9b2, as shown in FIG. 4. This allows the left-right distance G1 between the left side plate 5b and the bottom plate 5a to be adjusted to any desired length. Similarly, the other end of the connecting belt 9a, one end of which is fixed to the right side plate 5b, is threaded through the two right-hand D-shaped pipes 9b3 and 9b4, as shown in FIG. 4. This allows the left-right distance G2 between the right side plate 5b and the bottom plate 5a to be adjusted to any desired length. Since the (left-right) distances G1 and G2 between the pair of left and right side plates 5b and the bottom plate 5a can be adjusted in this way, the container can accommodate various left-right dimensions of the transported object C. The left and right connecting belts 9a and the four D-shaped tubes 9b (9b1 to 9b4) are examples of the "second connecting means" of the present invention, and are equipped with a distance adjustment mechanism that adjusts the distance between the pair of left and right side plate portions 5b and the bottom plate portion 5a.

[0038] Fig. 5 is a schematic left side view of the carrier 1 shown in Fig. 1, with Fig. 5(a) being a schematic left side view of the carrier 1 showing a state in which the distance between the back support plate 3 and the bottom plate 5a is relatively narrow, and Fig. 5(b) being a schematic left side view of the carrier 1 showing a state in which the distance between the back support plate 3 and the bottom plate 5a is relatively wide. The bottom plate 5a is located to the left of the right side plate 5b (the back side of the drawing) and would normally be hidden by the right side plate 5b, but for ease of explanation, Fig. 5 shows the right side plate 5b shifted slightly upward to expose the bottom plate 5a.

[0039] As shown in Figures 3 and 5, a hook-and-loop fastener 8b is provided on the underside of the front portion of the bottom plate 5a. The hook-and-loop fastener 8b is attached to another portion of the hook-and-loop fastener 8a, a portion of which is fixed to the lower end of the back support plate 3, thereby connecting the front portion of the bottom plate 5a to the lower part of the back support plate 3. The distance G3 in the front-to-rear direction between the back support plate 3 and the bottom plate 5a can be adjusted by changing the relative positions of the hook-and-loop fasteners 8a, 8b in the front-to-rear direction (more specifically, the front-to-rear position of the hook-and-loop fastener 8b with respect to the hook-and-loop fastener 8a). The hook-and-loop fasteners 8a, 8b are an example of a "first connecting means" in the present invention.

[0040] As described above, the left and right support belts 6a of the first belt member 6 are inserted through the insertion portions 5b3 of the left and right side plates 5b. Therefore, the left side plate 5b can slide along the left support belt 6a, and the right side plate 5b can slide along the right support belt 6a, respectively, in the approximately front-to-rear direction (in accordance with the position of the bottom plate 5a in the front-to-rear direction). In addition, the right belt 6c of the first belt member 6 is provided with a male buckle 6c1 equipped with an adjuster mechanism.

[0041] Therefore, by changing the front-to-rear positions of the bottom plate 5a and the left and right side plate 5b in accordance with the center of gravity of the transported item C and further adjusting the length of the right belt 6c (and therefore the length of the first belt member 6), it is possible to accommodate a variety of transported items with different front-to-rear dimensions (= depth dimensions). Note that the height of the transported item C can be easily accommodated even if it is significantly higher than the back support plate 3 shown in Fig. 2 etc.

[0042] 1 and 5, each side plate 5b has a rear upper edge 5b4 that slopes downward toward the rear. This configuration prevents the rear upper edges 5b4 of the pair of left and right side plates 5b from interfering with (contacting) the lid C1 when transporting an item C with a lid C1 on top, as in a typical insulated container, and the lid C1 is rotated around a pivot point located on the front side of the item C (the side of the back support plate 3) as shown by the dashed line with an arrow in FIG. 2 to open and close the lid C1. Therefore, the lid C1 of the item C can be smoothly opened and closed while the item C is supported by the support portion 5.

[0043] Fig. 6 is a schematic plan view showing the folded state of the carrier 1 shown in Fig. 1. In Fig. 6, the belt members (2, 6, 7, 9a, etc.) are omitted for the sake of convenience.

[0044] In the carrier 1 according to this embodiment, by undoing the buckles 6b1, 6b2 and 7a1, 7b1 and adjusting the length of the connecting belt 9a (greatly widening the gap between the bottom plate 5a and the pair of left and right side plates 5b), the carrier 1 can be folded compactly by stacking the back plate 3, the bottom plate 5a, and the pair of left and right side plates 5b in this order from above. It is also possible to fold the carrier 1 so that the pair of left and right side plates 5b are sandwiched between the back plate 3 and the bottom plate 5a. In this case, it is preferable to place the pair of left and right side plates 5b horizontally on the back plate 3 so that the longitudinal direction of the pair of left and right side plates 5b is parallel to the lateral direction of the back plate 3. In either folding method, the hook-and-loop fasteners 8a, 8b remain attached to each other when the carrier 1 is folded.

[0045] As shown in Fig. 5, each of the pair of left and right shoulder belts 2 includes an outer belt 2a, one end of which is attached to the front of the back support plate 3, an inner belt 2b attached to the inside of the outer belt 2a, and a pressure belt 2c that presses against the outer belt 2a from the outside. A gap 2d is formed between the outer belt 2a and the inner belt 2b, and the presence of this gap 2d reduces the load on the shoulders of the carrier. The pressure belt 2c includes an adjuster 2c1 for adjusting its length. The carrier can adjust the length of the pressure belt 2c using this adjuster 2c1, thereby adjusting the force with which the outer belt 2a is pressed inward (toward the inner belt 2b) and changing the size of the gap 2d. <Technical significance of the first embodiment>

[0046] According to the first embodiment shown in Figures 1 to 6, the back support plate portion 3, the front of which abuts against the carrier's back, the bottom plate portion 5a, which supports the transported item C from below, and the pair of left and right side plate portions 5b, which hold down the transported item C from both sides, are all made of resin material, so the carrier 1 can be made significantly lighter than if it were made of metal, and therefore it is easier for the carrier to carry the carrier 1 supporting the transported item C on their backs for long periods of time.

[0047] Furthermore, according to the first embodiment, the first belt members 6 attached to the back support plate 3 engage with the left and right side plates 5b (more specifically, pass through the insertion portions 5b3 of the left and right side plates 5b) and are wound around the rear side of the transported article C, preventing the left and right side plates 5b from falling outward in the left-right direction when pressed by the transported article C, and preventing the transported article C from falling backward as the bottom plate 5a bends due to the weight of the transported article C. Therefore, the transported article C can be transported stably despite its light weight.

[0048] In addition, according to the first embodiment, each of the left and right side plate portions 5b has an insertion portion 5b3 formed therein through which the first belt member 6 is inserted twice, and in each insertion portion 5b3, the first insertion point I1 and the second insertion point I2 are positioned vertically differently, so that each of the left and right side plate portions 5b can be firmly held in an upright position (= erect position, standing position), and therefore, the left and right side plate portions 5b can be effectively prevented from being pushed sideways by the transported item C.

[0049] Furthermore, according to the first embodiment, as shown in Figure 4, the distances G1, G2 between the bottom plate portion 5a and the pair of left and right side plate portions 5b can be adjusted using the connecting belt 9a and the D-tube 9b, so that the carrier can change the left-right position of each side plate portion 5b to accommodate transported items C of various left-right dimensions.

[0050] Furthermore, according to the first embodiment, the distance between the bottom plate portion 5a and the pair of left and right side plate portions 5b is widened using the connecting belt 9a and the D-tube 9b, so that the back support plate portion 3, the bottom plate portion 5a, and the pair of left and right side plate portions 5b can be folded compactly by stacking them in order, as shown in Figure 6.

[0051] In addition, according to the first embodiment, as shown in Figure 5, the distance G3 between the back support plate portion 3 and the bottom plate portion 5a can be adjusted by changing the relative positions of the hook-and-loop fasteners 8a, 8b in the front-to-back direction, and the first belt member 6 is inserted in approximately the front-to-back direction through the insertion portions 5b3 formed on each of the left and right side plate portions 5b.Therefore, the carrier can change the front-to-back position of the bottom plate portion 5a to match the position of the center of gravity in the front-to-back direction of the item C to be transported, slide the pair of left and right side plate portions 5b back and forth along the first belt member 6, and further adjust the length of the first belt member 6 using the buckle 6c1 equipped with an adjuster mechanism, thereby accommodating items with various front-to-back dimensions (= depth dimensions).

[0052] Furthermore, according to the first embodiment, the upper belt 7a of the second belt member 7, which passes above and behind the transported item C and is configured to be able to connect the upper part of the back support plate portion 3 and the rear part of the bottom plate portion 5a, has a male buckle 7a1 equipped with an adjuster mechanism for adjusting its length.Therefore, after the transporter places the transported item C on the bottom plate portion 5a, the buckles 7a1 and 7b1 are connected and the upper belt 7a is tightened (=adjusted to be shorter), thereby preventing the transported item C from tilting backward.

[0053] Furthermore, according to the first embodiment, the pair of left and right side plate portions 5b are formed so that the rear upper edges 5b4 are inclined downward toward the rear, so that when transporting an article C with a lid C1 on top, such as a general insulated container (insulated box), the rear upper edges 5b4 of the pair of left and right side plate portions 5b are unlikely to interfere with (come into contact with) the lid C1 when the lid C1 is opened or closed, allowing the lid C1 to be opened and closed smoothly. FIG. 7 is a development view of a carrier 1 according to a second embodiment of the present invention. The carrier 1 according to this embodiment is configured similarly to the first embodiment except for the points described below, and therefore can achieve similar effects.

[0054] In this embodiment, the bottom plate 5a does not have a D-shaped loop 9b on its underside, and the left and right side plates 5b do not have connecting belts 9a. Instead, hook-and-loop fasteners 9c are provided on the left and right sides of the underside of the bottom plate 5a, and hook-and-loop fasteners 9d are provided on each of the side plates 5b. Each hook-and-loop fastener 9c is completely affixed (sewn) to the underside of the bottom plate 5a, and only a portion (top) of each of the left and right hook-and-loop fasteners 9d is affixed (sewn) to the side plates 5b. The remaining unattached portions of the left and right hook-and-loop fasteners 9d are attached from below to the left and right hook-and-loop fasteners 9c attached to the underside of the bottom plate 5a, thereby connecting the bottom plate 5a to the pair of left and right side plates 5b. Note that the surfaces of the left and right hook-and-loop fasteners 9d that are attached to the hook-and-loop fasteners 9c are the surfaces (back surfaces) hidden in FIG. 7.

[0055] In this way, by using the hook-and-loop fasteners 9c and 9d, the carrier can change the relative position of the hook-and-loop fastener 9d with respect to the hook-and-loop fastener 9c, and freely adjust the (left-right) spacing between the bottom plate portion 5a and the pair of side plate portions 5b, thereby accommodating items of various left-right dimensions.

[0056] In addition, when folding the carrier 1, the hook-and-loop fasteners 9c and 9d are peeled off and the bottom plate portion 5a and the pair of side plate portions 5b are separated, so that the carrier 1 can be folded so that the back support plate portion 3, the bottom plate portion 5a, and the pair of left and right side plate portions 5b are stacked in that order, as in the first embodiment.

[0057] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims, and it goes without saying that these modifications are also included within the scope of the present invention.

[0058] For example, in the first and second embodiments, hook-and-loop fasteners 8a, 8b are used as the first connecting means for connecting the back support plate portion 3 and the bottom plate portion 5a, but it is not necessarily necessary to use hook-and-loop fasteners 8a, 8b as the first connecting means, and other connecting means such as belts may also be used.

[0059] Similarly, in the first embodiment, left and right connecting belts 9a and four D-shaped tubes 9b (9b1-9b4) are used as second connecting means for connecting the bottom plate 5a and the pair of left and right side plate portions 5b, while in the second embodiment, hook-and-loop fasteners 9c and 9d are used. However, the second connecting means is not limited to these. Also, in the first embodiment, a single connecting belt 9a is provided on each of the left and right side plate portions 5b to connect the left and right side plate portions 5b to the bottom plate portion 5a, but multiple connecting belts may also be used. For example, by providing connecting belts at the front and rear of each of the left and right side plate portions 5b, the posture of the left and right side plate portions 5b can be further stabilized.

[0060] Additionally, in the first and second embodiments, the second belt member 7 is provided to extend substantially in the front-to-rear direction above the transported item C, but it is also possible to attach a belt with a male buckle to the upper part of one of the left and right side plate portions 5b, and attach a belt with a female buckle connectable to the male buckle to the upper part of the other of the left and right side plate portions 5b, so that the buckles of these belts can be connected to each other above the transported item C. In this way, by providing a belt that extends left and right above the transported item C so as to be perpendicular to the second belt member 7, the transported item C can be more firmly fixed to the support portion 5 and the contents can be effectively prevented from spilling out.
