Description

Technical Field

[0001] The utility model relates to a hanging device for installing a refrigerated insulation box on a cage truck for installation, and a refrigerated insulation box for a cage truck equipped with the hanging device. Background Art

[0002] Generally, various fresh foods and in-flight meals on airplanes need to be refrigerated or insulated. Therefore, containers with refrigeration and insulation functions are used during transportation.

[0003] In the past, as a transportation container for refrigeration and insulation, for example, a box (hereinafter referred to as a "refrigerated insulation box") sewn with a flexible heat-insulating material was used. This refrigerated insulation box is usually installed on a cage truck for use.

[0004] Here, refer to Figure 7 and Figure 8 to illustrate the structure of the "cage truck", which is the installation object of the above-mentioned "refrigerated insulation box".

[0005] Figure 7 is a perspective view of a cage truck for installation used to install a refrigerated insulation box. Figure 8 shows Figure 7 a perspective view of the folded state of the cage truck for installation shown.

[0006] As Figure 7 shown, the cage truck 111 for installation mainly consists of a back wall surface 112, a right wall surface 113, a left wall surface 114 made of a metal grid, and a flat bottom surface 115. More specifically, in the cage truck 111 for installation, the back wall surface 112, the right wall surface 113, and the left wall surface 114 are erected around the flat bottom surface 115.

[0007] In addition, as Figure 7 shown, in the cage truck 111 for installation, the back wall surface 112 and the right wall surface 113, and the back wall surface 112 and the left wall surface 114 are all connected by hinges 116. Therefore, as Figure 8 shown, the cage truck 111 for installation can be folded so that the right wall surface 113 and the left wall surface 114 are respectively folded on the inner side surface of the back wall surface 112.

[0008] Furthermore, although not shown in Figure 7 and Figure 8 , the bottom surface 115 in the cage truck 111 for installation is provided at the lower end of the back wall surface 112 through a hinge (not shown).

[0009] Therefore, when folding the cage truck 111 for installation, before folding the right wall surface 113 and the left wall surface 114 to the inner side surface of the back wall surface 112, it is necessary to first lift the bottom surface 115 and fold it onto the inner side surface of the back wall surface 112.

[0010] In addition, asFigure 7 and Figure 8 As shown in Figure 8 , casters 119 are respectively installed directly below the hinge 116 connecting the back wall surface 112 and the right wall surface 113, directly below the hinge 116 connecting the back wall surface 112 and the left wall surface 114, and below the open ends of the right wall surface 113 and the left wall surface 114 in the installation cage cart 111.

[0011] In this way, the caster 119 installed below the open end of the right wall surface 113 moves as the right wall surface 113 rotates, and the caster 119 installed below the open end of the left wall surface 114 moves as the left wall surface 114 rotates.

[0012] In addition, in the installation cage cart 111, the right wall surface 113 and the left wall surface 114 are respectively configured to rotate freely through the hinge 116, and the bottom surface 115 is supported by support plates 120 respectively provided at the bottom ends of the right wall surface 113 and the left wall surface 114.

[0013] Therefore, when the bottom surface 115 is in a horizontally set state, if the right wall surface 113 and / or the left wall surface 114 rotate and open, the bottom surface 115 will lose support and tilt towards the ground, and the installation cage cart 111 is in a so-called bottomless state.

[0014] To avoid this situation, the installation cage cart 111 is equipped with an anti-opening cross bar 117 and a hook portion 118 as shown in Figure 7 and Figure 8 . Figure 7 and Figure 8 As shown in Figure 8 , in a state where each part of the installation cage cart 111 is configured to form a hollow container shape, the bent front end portion of the anti-opening cross bar 117 is inserted into the cylindrical body of the hook portion 118 to prevent the right wall surface 113 and the left wall surface 114 from accidentally opening and moving to the left and right respectively.

[0015] In other words, as shown in Figure 7 , in a state where each part of the installation cage cart 111 is configured to form a hollow container shape, the bent front end portion of the anti-opening cross bar 117 is inserted into the cylindrical body of the hook portion 118 to prevent the right wall surface 113 and the left wall surface 114 from accidentally opening and moving to the left and right respectively. Figure 7 As shown in Figure 7 , in a state where each part of the installation cage cart 111 is configured to form a hollow container shape, the bent front end portion of the anti-opening cross bar 117 is inserted into the cylindrical body of the hook portion 118 to prevent the right wall surface 113 and the left wall surface 114 from accidentally opening and moving to the left and right respectively.

[0016] Moreover, the cold storage and heat preservation box for cage carts used on the above-mentioned installation cage cart 111 can not only be detachably installed on the installation cage cart 111, but also needs to have the following structure, that is, in a state where the cold storage and heat preservation box for cage carts is installed on the installation cage cart 111, the installation cage cart 111 can be folded.

[0017] In the past, the applicant of the present utility model invented a cold storage and heat preservation box for cage carts used on the installation cage cart 111 as shown in Figure 7 and Figure 8 , and applied for a patent as Patent Document 1. Figure 7 and Figure 8 As shown in Figure 8 , and applied for a patent as Patent Document 1.

[0021] Technical problem

[0022] When the refrigerated and heat-insulated box for a cage car or the refrigerated and heat-insulated box for a cage car disclosed in Patent Document 1 is installed on an installation cage car for use, it can be found that the place near the front part of the wide hook hooked on the upper side of the right wall surface or the upper side of the left wall surface is prone to breakage.

[0023] More specifically, it can be found that the boundary between the hooking part and the flat part near the front part of the wide hook is prone to breakage.

[0024] The present utility model is proposed to solve the above-mentioned existing situation, and its purpose is to prevent breakage of the hooking device for installing the refrigerated and heat-insulated box for a cage car on an installation cage car, and to provide a more durable refrigerated and heat-insulated box for a cage car. Summary of the Invention

[0025] A hooking device as a first solution for solving the above problems is characterized in that: the hooking device is hooked on the upper sides of the right wall surface and the left wall surface of an installation cage car including a back wall surface, a right wall surface, a left wall surface and a bottom surface, and detachably installs a refrigerated and heat-insulated box on the installation cage car. The hooking device includes a hook-shaped hooking part formed by bending or folding a flat plate made of metal or synthetic resin; a flat plate part integrally extending with the hooking part; and a flat tongue part. When the hooking device is installed on the above refrigerated and heat-insulated box, the tongue part protrudes on the side close to the front part of the refrigerated and heat-insulated box and is integrally extended with the above flat plate part.

[0026] In the hooking device of the first solution with the above configuration, when the hooking device of the first solution is installed on the refrigerated and heat-insulated box, the hooking parts are respectively hooked on the upper sides of the right wall surface and the left wall surface of the installation cage car, and have the function of fixing the refrigerated and heat-insulated box in the internal space of the installation cage car.

[0027] The flat plate part serves as a fixing part when the hooking device of the first solution is installed on the refrigerated and heat-insulated box.

[0028] The tongue part has the following functions: when the hooking device of the first solution is installed on the refrigerated and heat-insulated box, it keeps as flat as possible the components such as plates that are the installation objects of the hooking device and are arranged around the side of the hooking part. The plates and the like are components arranged on the side of the refrigerated and heat-insulated box.

[0029] In this way, when using the hooking device of the first solution, it has the function of preventing the components arranged around the side of its hooking part from bending or deflecting.

[0030] Therefore, when using the hanging device as the first solution, the force that pulls the hanging part and the flat part apart is suppressed as much as possible from acting on the boundary between the hanging part and the flat part.

[0031] In other words, since the hanging device as the first solution is provided with a tongue part, when the hanging device is used after being set on the cold storage and heat preservation box, breakage of the boundary part between the hanging part and the flat part provided near the front part is suppressed.

[0032] The hanging device as the second solution is characterized in that: in the hanging device of the first solution, the connecting part between the hanging part and the tongue part is arc-shaped.

[0033] The hanging device of the second solution configured as above has the following effect: during its use, when the force that pulls the hanging part and the flat part apart acts on the boundary between the hanging part and the flat part, at the arc-shaped part, the stress acting on the connecting part between the hanging part and the tongue part is dispersed and relieved.

[0034] In other words, according to the hanging device as the second solution, when it is installed on the cold storage and heat preservation box for use, breakage of the boundary between the hanging part and the flat part provided near the front part can be more effectively prevented.

[0035] The hanging device as the third solution is characterized in that: in the hanging device of the first solution or the second solution, the corner of the tongue part is curved.

[0036] The hanging device of the third solution configured as above has the following effect: during its use, or when the hanging device as the third solution is installed on the cold storage and heat preservation box, it prevents the corner of the tongue part from damaging the components constituting the cold storage and heat preservation box.

[0037] The hanging device as the fourth solution is characterized in that: in the hanging device of the first solution or the second solution, a sewing groove is formed on the flat part and the tongue part, the sewing groove is parallel to the extending direction of the hanging part, and the cross-sectional shape in the thickness direction of the flat part is concave.

[0038] The hanging device of the fourth solution configured as above has the following effect: by forming the sewing groove on the flat part and the tongue part, the thickness of the flat plate in the sewing groove is locally thinned.

[0039] In this case, even if the thickness of the parts other than the sewing groove in the flat part and the tongue part is large, the sewing needle can be inserted into the sewing groove. In this way, the hanging device as the fourth solution can be sewn to the components constituting the cold storage and heat preservation box.

[0040] In addition, when the hanging device as the fourth solution is sewn to the components constituting the cold storage and heat preservation box, the sewing thread can be accommodated in the sewing groove, thereby protecting the sewing thread from friction during the use of the cold storage and heat preservation box.

[0041] A refrigerated and insulated box for a cage truck as a fifth solution, characterized in that: the refrigerated and insulated box for the cage truck is detachably arranged on the mounting cage truck, the mounting cage truck includes a back wall surface, a right wall surface, a left wall surface and a bottom surface, and the refrigerated and insulated box for the cage truck includes: a back portion covering the back wall surface; a right side portion covering the right wall surface; a left side portion covering the left wall surface; a top portion, the top portion is arranged to connect the upper edge of the back portion, the upper edge of the right side portion and the upper edge of the left side portion; a front portion, the front portion is arranged to connect the side edge of the right side portion that is not connected to the back portion and the side edge of the left side portion that is not connected to the back portion; and, the hook device described in the first solution or the second solution, the hook device is directly fixed on the right side portion and the left side portion respectively, and the flat portion and the tongue portion of the hook device are in direct or indirect surface contact with the outer side surface of the right side portion or the left side portion and are fixed on the outer side surface of the right side portion or the left side portion.

[0042] The refrigerated and insulated box for a cage truck as the fifth solution with the above configuration has the following functions: the back portion, the right side portion and the left side portion of the refrigerated and insulated box for the cage truck respectively cover the inner side surface of the back wall surface of the cage truck, the inner side surface of the right side wall and the inner side surface of the left side wall, and form the side surfaces of a cubic container.

[0043] The top portion of the refrigerated and insulated box for the cage truck is connected to the upper edge of the back portion, the upper edge of the right side portion and the upper edge of the left side portion respectively, and has the function of forming the top portion of the above cubic container.

[0044] The front portion of the refrigerated and insulated box for the cage truck is connected to the side edge of the right side portion, the side edge of the left side portion and a part of the periphery of the top portion, and has the function of forming the front portion of the above cubic container.

[0045] The hook device in the fifth solution has the same function as the hook device described in the first solution or the second solution.

[0046] According to the hook device of the first solution, the breakage of the hook device during use can be effectively prevented, and the hook device detachably mounts the refrigerated and insulated box for the cage truck to the mounting cage truck.

[0047] Therefore, according to the hook device of the first solution, a hook device for a refrigerated and insulated box for a cage truck that is more difficult to break than the wide hook disclosed in Patent Document 1 can be provided.

[0048] Therefore, the durability of the refrigerated and insulated box for a cage truck (i.e., the fifth solution) provided with the hook device of the first solution can be improved.

[0049] According to the hook device of the second solution, a hook device that is more difficult to break than the first solution can be provided.

[0050] Therefore, compared with the cage truck refrigerated insulation box provided with the hanging device as the first solution, the durability of the cage truck refrigerated insulation box provided with the hanging device as the second solution (i.e., the fifth solution) can be improved.

[0051] According to the hanging device of the third solution, during its use or when the hanging device of the third solution is installed on the refrigerated insulation box, damage such as holes in the components constituting the refrigerated insulation box can be prevented.

[0052] Therefore, according to the hanging device of the third solution, a hanging device that is easy to operate can be provided.

[0053] According to the hanging device of the fourth solution, when manufacturing the cage truck refrigerated insulation box, the hanging device of the fourth solution can be sewn to the components constituting the refrigerated insulation box.

[0054] In this case, compared with the case of fixing the hanging device of the fourth solution to the components constituting the refrigerated insulation box using an adhesive or the like or fixing it by thermal welding, the equipment for the fixing operation can be simplified.

[0055] Therefore, the manufacturing cost of the cage truck refrigerated insulation box provided with the hanging device of the fourth solution can be made low. BRIEF DESCRIPTION OF THE DRAWINGS

[0123] Reference Figures 1 to 6 This document describes the hook device provided by the embodiments of the present utility model and the cage vehicle refrigerated insulation box equipped with this hook device.

[0124] [1; Basic structure of the present utility model]

[0125] (Regarding the hook device)

[0126] The following will introduce the hook device provided by the representative embodiment of the present utility model (hereinafter referred to as this embodiment) and the cage vehicle refrigerated insulation box equipped with this hook device.

[0127] Figure 1 is a perspective view of the hook device provided by this embodiment. Figure 2 is a perspective view of the cage vehicle refrigerated insulation box provided by this embodiment.

[0128] The hook device 1A provided by this embodiment is used to Figure 2 detachably mount the refrigerated insulation box 19 shown in Figure 3 on the mounting cage vehicle 20 shown below.

[0129] For example, as Figure 1 shown, the hook device 1A provided by this embodiment includes a hook-shaped hook portion 3 formed by bending or folding a flat plate 2 made of metal or synthetic resin; a flat plate portion 4 integrally extending with the hook portion 3; and a flat tongue portion 5. When the hook device 1A is mounted on the refrigerated insulation box 19 described below, the tongue portion 5 protrudes on the first side S1 close to the front portion 15 of the refrigerated insulation box 19 and is integrally extended with the flat plate portion 4.

[0130] (Regarding the mounting cage vehicle)

[0131] Before introducing the cage vehicle refrigerated insulation box provided by this embodiment, first refer to Figure 3 to introduce the structure of the mounting object, i.e., the mounting cage vehicle.

[0132] Figure 3 is a perspective view showing the state where the cage vehicle refrigerated insulation box provided by this embodiment is mounted on the mounting cage vehicle.

[0133] In addition, the mounting cage vehicle 20 has the same structure and function as the mounting cage vehicle 111 shown in Figure 7 and Figure 8 above.

[0134] More specifically, for example, as Figure 3As shown, the installation cage cart 20 is mainly composed of a back wall surface 21, a right wall surface 22, a left wall surface 23 made of metal mesh, and a flat bottom surface 24. More specifically, in the installation cage cart 20, the back wall surface 21, the right wall surface 22, and the left wall surface 23 are erected around the flat bottom surface 24.

[0135] In addition, as Figure 3 shown, in the installation cage cart 20, the back wall surface 21 and the right wall surface 22, and the back wall surface 21 and the left wall surface 23 are both connected by hinges 25. Therefore, the installation cage cart 20 can be folded, and the right wall surface 22 and the left wall surface 23 are respectively folded on the inner side surface of the back wall surface 21.

[0136] Furthermore, although not shown in Figure 3 , the bottom surface 24 in the installation cage cart 20 is provided at the lower end of the back wall surface 21 through a hinge not shown.

[0137] Therefore, when folding the installation cage cart 20, before folding the right wall surface 22 and the left wall surface 23 to the inner side surface of the back wall surface 21, it is necessary to first lift and fold the bottom surface 24 onto the inner side surface of the back wall surface 21.

[0138] In addition, as Figure 3 shown, the installation cage cart 20 is respectively equipped with casters 28 directly below the hinge 25 connecting the back wall surface 21 and the right wall surface 22, directly below the hinge 25 connecting the back wall surface 21 and the left wall surface 23, and below the open ends of the right wall surface 22 and the left wall surface 23.

[0139] In this way, the caster 28 provided below the open side of the right wall surface 22 moves as the right wall surface 22 rotates, and the caster 28 provided below the open end of the left wall surface 23 moves as the left wall surface 23 rotates.

[0140] In addition, in the installation cage cart 20, the right wall surface 22 and the left wall surface 23 are respectively configured to rotate freely through the hinge 25, while the bottom surface 24 is supported by support plates 29 respectively provided at the bottom ends of the right wall surface 22 and the left wall surface 23.

[0141] Therefore, in a state where the bottom surface 24 is horizontally set, if the right wall surface 22 and / or the left wall surface 23 rotate and open, the bottom surface 24 will lose support and tilt towards the ground, and the installation cage cart 20 is in a so-called bottomless state.

[0142] To avoid this situation, the installation cage cart 20 is equipped with an anti-opening cross bar 26 and a hook portion 27 as Figure 3 shown.

[0143] In other words, as Figure 3As shown, with each part of the installation cage truck 20 configured to form a hollow container shape, the bent front end portion of the anti-opening cross bar 26 is inserted into the cylinder of the hooking portion 27 to prevent the right wall surface 22 and the left wall surface 23 from accidentally opening and moving to the left and right respectively.

[0144] Moreover, the cage truck refrigerated insulation box 10A provided in this embodiment used on the above-mentioned installation cage truck 20 can not only be detachably installed on the installation cage truck 20, but also needs to have the following structure, that is, in the state where the cage truck refrigerated insulation box 10A is installed on the installation cage truck 20, the installation cage truck 20 can be folded.

[0145] (Regarding the cage truck refrigerated insulation box)

[0146] Reference Figure 2 and Figure 3 Describe the cage truck refrigerated insulation box 10A provided in this embodiment.

[0147] The cage truck refrigerated insulation box 10A provided in this embodiment is installed on Figure 3 the shown installation cage truck 20 for use.

[0148] The refrigerated insulation box 19 includes a back portion 11, a right side portion 12, and a left side portion 13. The back portion 11, the right side portion 12, and the left side portion 13 respectively cover the back wall surface 21, the right wall surface 22, and the left wall surface 23 of the installation cage truck 20.

[0149] In addition, the refrigerated insulation box 19 further includes a top portion 14, and the top portion 14 is arranged to connect the upper edge 11a of the back portion 11, the upper edge 12a of the right side portion 12, and the upper edge 13a of the left side portion 13.

[0150] In addition, the refrigerated insulation box 19 further includes a front portion 15, and the front portion 15 is arranged to connect the upper edge 12a of the right side portion 12, the upper edge 13a of the left side portion 13, and the side edge on the front side of the top portion 14.

[0151] The back portion 11, the right side portion 12, the left side portion 13, the top portion 14, and the front portion 15 constituting the refrigerated insulation box 19 are all composed of a heat insulating material having one of waterproofness or light shielding property, or both, and this kind of heat insulating material usually has flexibility.

[0152] On the other hand, the back portion 11, the right side portion 12, and the left side portion 13 do not necessarily have to be flexible, as long as their structures allow adjacent parts to rotate relative to each other at their connection positions.

[0153] Alternatively, according to the usage purpose of the cold storage and insulation box 19, the desired parts among the back part 11, the right side part 12, the left side part 13, the top part 14, and the front part 15 may be made of a flexible material, while the other parts may be made of a material with sufficient shape retention.

[0154] In the cage car cold storage and insulation box 10A provided in this embodiment, hook hanging devices 1A are respectively provided on the right side part 12 and the left side part 13 of the cold storage and insulation box 19. In addition, the back part 11 of the cold storage and insulation box 19 may also be provided with, for example, a hook hanging device 1B that does not have the tongue part 5 of the aforementioned hook hanging device 1A, that is, a hook hanging device having the same wide hook structure as that disclosed in the aforementioned Patent Document 1. Figure 1 More specifically, in the cage car cold storage and insulation box 10A provided in this embodiment, hook hanging devices 1A are respectively provided near the upper edge 12a of the outer side surface of the right side part 12 and near the upper edge 13a of the outer side surface of the left side part 13 in the cold storage and insulation box 19. In addition, the cage car cold storage and insulation box 10A provided in this embodiment may be provided with a hook hanging device 1B near the upper edge 11a of the outer side surface of the back part 11.

[0155] The method of fixing the hook hanging device 1A or the hook hanging device 1B to each part constituting the cold storage and insulation box 19 can be appropriately selected according to the usage purpose of the cage car cold storage and insulation box 10A, for example, by bonding with an adhesive, sewing, or fixing with fixing members such as rivets or bolts and nuts. In other words, as long as the hook hanging device 1A or the hook hanging device 1B can be fixed to the side surface of the cold storage and insulation box 19 in a stable state, any fixing method can be adopted.

[0156] In the cage car cold storage and insulation box 10A provided in this embodiment, the hook hanging device 1A or the hook hanging device 1B is directly fixed to the side surface of the cold storage and insulation box 19.

[0157] Here, "directly fixing the hook hanging device 1A or the hook hanging device 1B" means that the flat part 4 and the tongue part 5 of the hook hanging device 1A or the flat part 4 of the hook hanging device 1B are directly or indirectly in surface contact with the side surface of its installation object, that is, the outer side surface of the cold storage and insulation box 19 (i.e., the right side part 12, the left side part 13, or the back part 11), and the hook hanging device 1A or the hook hanging device 1B is fixed in a non-movable state in the surface contact state.

[0158] In addition, especially when the hook hanging device 1A or the hook hanging device 1B is sewn to the side surface of the cold storage and insulation box 19, needle insertion holes may be pre-formed on the flat part 4 and the tongue part 5 of the hook hanging device 1A or the flat part 4 of the hook hanging device 1B for inserting a sewing needle (not shown).

[0160] In this case, even if the thickness of the flat portion 4 and the tongue portion 5 of the hooking device 1A is relatively large, or the thickness of the flat portion 4 of the hooking device 1B is relatively large, the hooking device 1A or the hooking device 1B can be easily sewn to the components constituting the refrigerated insulation box 19.

[0161] (Regarding the opening structure of the refrigerated insulation box for the cage truck)

[0162] Figure 4 It is a side view of an important part of the refrigerated insulation box for the cage truck provided by this embodiment.

[0163] The refrigerated insulation box 10A for the cage truck provided by this embodiment includes an opening for putting items into and taking items out of the refrigerated insulation box 19.

[0164] In addition, the refrigerated insulation box 10A for the cage truck provided by this embodiment also needs to be configured such that the mounting cage truck 20 can be folded in a state where the refrigerated insulation box 10A for the cage truck is mounted on the mounting cage truck 20. Therefore, the refrigerated insulation box 10A for the cage truck provided by this embodiment has a deployable structure.

[0165] More specifically, in the refrigerated insulation box 10A for the cage truck provided by this embodiment, for example, as Figure 4 shown, the top surface portion 14 and the front surface portion 15 in the refrigerated insulation box 19 are longitudinally connected. In addition, the connecting portions of the connected top surface portion 14 and front surface portion 15 with the right side surface portion 12 and the left side surface portion 13 have a joining structure such as a zipper.

[0166] In this way, by releasing the joined state of the above joining structure, that is, for example, by opening the zipper, as Figure 4 shown, the connecting body of the top surface portion 14 and the front surface portion 15 in the refrigerated insulation box 19 can be lifted vertically upward. In this way, an opening is formed on the front side of the refrigerated insulation box 19, and items can be taken in and out.

[0167] In addition, this state is also the deployable state of the refrigerated insulation box 10A for the cage truck provided by this embodiment.

[0168] More specifically, the refrigerated insulation box 10A for the cage truck provided by this embodiment is respectively provided with a joining structure such as a zipper on the upper edge 12a and side edge 12b of the refrigerated insulation box 19 and the upper edge 13a and side edge 13b.

[0169] In this case, as Figure 4 shown, the connecting body of the front surface portion 15 and the top surface portion 14 can be lifted to the upper edge 11a of the back surface portion 11. In this way, an opening is formed on the front side of the refrigerated insulation box 19, and items can be taken in and out from this opening to the inside.

[0170] At this time, in the installation cage truck 20, the right wall surface 22 with the right side portion 12 and the left wall surface 23 with the left side portion 13 can be rotated to the inner side surface of the back wall surface 21 with the back portion 11. In other words, in the state where the refrigerated insulation box 10A for cage trucks provided in this embodiment is installed on the installation cage truck 20, the installation cage truck 20 can be folded.

[0171] As the joining structure of the respective parts constituting the refrigerated insulation box 19, in addition to the zipper, other conventional well-known joining structures can be used without any problem, such as hook-and-loop fasteners, linear zippers, snap buttons, etc. However, in the case where the sealing property or watertightness of the refrigerated insulation box 19 is emphasized, a zipper can be used as the joining structure.

[0172] (Regarding the usage method of the refrigerated insulation box for cage trucks)

[0173] Figure 5 is the enlarged view of the peripheral area of the hooking device in the above-mentioned Figure 3 above.

[0174] In Figure 2 the case where the refrigerated insulation box 10A for cage trucks provided in the present embodiment shown in Figure 3 and Figure 5 is installed on the installation cage truck 20, as shown in

[0175] hook the hooking portions 3 of the hooking devices 1A respectively on the upper edges 22a of the right wall surface 22 and the upper edges 23a of the left wall surface 23 of the installation cage truck 20, and hook the hooking portion 3 of the hooking device 1B on the upper edge 21a of the back wall surface 21.

[0176] [2; Regarding the function and effect of the present utility model]

[0177] Since the hooking device 1A provided in this embodiment is provided with the tongue portion 5, when the refrigerated insulation box 10A for cage trucks with the hooking device 1A is installed on the installation cage truck 20 for use, it is possible to prevent the right side portion 12 or the left side portion 13 around the first side S1 of the hooking portion 3 in the hooking device 1A from being bent or flexed.

[0178] That is to say, the right side portion 12 or the left side portion 13 around the first side S1 of the hooking portion 3 in the hooking device 1A can be kept as flat as possible.

[0179] Thus, when the refrigerated insulated box 10A for cage trucks is used while being installed on the installation cage truck 20, and when a force is applied to pull the right side portion 12 away from the right wall surface 22 of the installation cage truck 20, or when a force is applied to pull the left side portion 13 away from the left wall surface 23 of the installation cage truck 20, at the boundary between the hook portion 3 and the flat plate portion 4 of the hooking device 1A, the presence of the tongue portion 5 can prevent a force from being applied to pull the hook portion 3 and the flat plate portion 4 apart.

[0180] Therefore, it is possible to prevent the boundary between the hook portion 3 and the flat plate portion 4 of the hooking device 1A provided in the present embodiment from being torn and damaged.

[0181] Therefore, according to the hooking device 1A provided in the present embodiment, it is possible to provide a hooking device that is more difficult to break than the wide hook disclosed in the aforementioned Patent Document 1.

[0182] In addition, by using the hooking device 1A provided in the present embodiment, it is possible to provide a refrigerated insulated box 10A for cage trucks that is more durable than the refrigerated insulated box for cage trucks disclosed in the aforementioned Patent Document 1.

[0183] [3; Details and variations of the present utility model, etc.]

[0184] (Regarding the manufacturing method of the hooking device)

[0185] Figure 1 The hooking device 1A provided in the present embodiment shown can be manufactured by extrusion molding.

[0186] More specifically, using a mold (not shown) that has a cutout portion having a shape that is the same as the cross-sectional shape perpendicular to the extending direction of the hook portion 3 in the portion of the hooking device 1A shown where the hook portion 3 is formed, the hooking device 1A is molded by extruding, for example, a synthetic resin having thermoplasticity from the cutout portion of the mold. Figure 1 After cutting the obtained extruded product into a required length, a part of the hook portion 3 near the end face can be cut off along the extending direction of the hook portion 3, and the flat plate portion 4 connected to the hook portion 3 is left to serve as the tongue portion 5.

[0187] Compared with the case of manufacturing the hooking device 1A by cutting a flat plate (not shown) into a required planar shape and then performing bending or other forming processes, when manufacturing the hooking device 1A provided in the present embodiment shown by extrusion molding, the manufacturing cost can be made low.

[0188] In addition, when manufacturing the hooking device 1A provided in the present embodiment by extrusion molding, it is very easy to set the length L1 in the extending direction of the hooking device 3 shown to a required length. Figure 1

[0189] Figure 1 Furthermore, when manufacturing the hooking device 1A provided in the present embodiment by extrusion molding, it is very easy to Figure 1 set the length L1 in the extending direction of the hooking device 3 shown to a required length.

[0190] Therefore, when the hooking device 1A provided in this embodiment is manufactured by extrusion molding, its manufacturing cost can be made low.

[0191] (Regarding the hooking device)

[0192] Figure 1 The illustrated hooking device 1A is described by taking as an example the case where the cross-section perpendicular to the extending direction of the hooking portion 3 is curved, but the shape of the cross-section perpendicular to the extending direction of the hooking portion 3 may also be curved into a hook shape. In this case, the same effect can be achieved.

[0193] As Figure 1 shown, in the hooking device 1A provided in this embodiment, the connecting portion 5a between the hooking portion 3 and the tongue portion 5 may be arc-shaped. In other words, the base portion of the hooking portion 3 and the base portion of the tongue portion 5 may be connected by a smooth curve.

[0194] In this case, when there is a force that pulls the hooking portion 3 and the flat plate portion 4 apart at the boundary between the hooking portion 3 and the flat plate portion 4 of the hooking device 1A, the arc-shaped portion of the connecting portion 5a between the hooking portion 3 and the tongue portion 5 can disperse and relieve this stress.

[0195] Therefore, it is possible to more effectively prevent the hooking device 1A provided in this embodiment from being damaged. Therefore, compared with the case of the hooking device 1A in which the connecting portion 5a between the hooking portion 3 and the tongue portion 5 is not arc-shaped, a more durable cage vehicle refrigerated insulation box 10A can be provided.

[0196] In addition, as Figure 1 shown, in the hooking device 1A provided in this embodiment, the corner 5b of the tongue portion may be curved.

[0197] In this case, when the hooking device 1A having the tongue portion 5 with the curved corner 5b is installed on the refrigerated insulation box 19, or when the cage vehicle refrigerated insulation box 10A provided with the hooking device 1A having the above-mentioned tongue portion 5 is used, the corner 5b of the tongue portion 5 can prevent the refrigerated insulation box 19 from being damaged such as having holes.

[0198] In this case, compared with the case of using the hooking device 1A in which the corner 5b of the tongue portion 5 is not curved, a more durable cage vehicle refrigerated insulation box 10A can be provided.

[0199] In addition, in the hooking device 1A provided in this embodiment, the corner 4a of the flat plate portion 4 may also be curved.

[0200] In this case, when the hooking device 1A with the flat part 4 having a bent corner 4a is mounted on the refrigerated insulation box 19, or when using the cage truck refrigerated insulation box 10A provided with the hooking device 1A having the flat part 4 with the bent corner 4a, the corner 4a of the flat part 4 can prevent damage such as holes in the refrigerated insulation box 19.

[0201] In this case, compared with the case of using the hooking device 1A with the flat part 4 whose corner 4a is not bent, a more durable cage truck refrigerated insulation box 10A can be provided.

[0202] Furthermore, on the flat part 4 and the tongue part 5 of the hooking device 1A provided in the present embodiment, a sewing groove 6 can be formed. The sewing groove 6 is parallel to the extending direction of the hooking part 3, and the cross-sectional shape in the thickness direction of the flat part 4 is concave.

[0203] In this way, by forming the sewing groove 6 on the flat part 4 and the tongue part 5, the thickness of the flat plate 2 in the sewing groove 6 can be locally thinned.

[0204] In this case, even if the thickness of the flat plate 2 outside the sewing groove 6 in the flat part 4 and the tongue part 5 is large, the hooking device 1A can be easily sewn to the side surface of the refrigerated insulation box 19.

[0205] Furthermore, when the sewing groove 6 is formed on the flat part 4 and the tongue part 5, the suture after sewing can be accommodated in the sewing groove 6.

[0206] In this case, when using the hooking device 1A provided in the present embodiment, the risk of the hooking device 1A falling off from the refrigerated insulation box 19 due to wear of the suture for fixing the hooking device 1A or the like can be reduced.

[0207] Furthermore, compared with the case of bonding the hooking device 1A to the refrigerated insulation box 19 using an adhesive or the case of thermally welding the hooking device 1A, when the hooking device 1A is sewn to the refrigerated insulation box 19, the equipment required for fixing the hooking device 1A can be simplified.

[0208] Therefore, the manufacturing cost of the cage truck refrigerated insulation box 10A provided in the present embodiment can be made low.

[0209] In Figure 1 , taking the case where three sewing grooves 6 are formed on the flat part 4 and the tongue part 5 of the hooking device 1A as an example, the number of the sewing grooves 6 can be any number from one to more.

[0210] However, when the hooking device 1A is mounted on the refrigerated insulation box 19, if the flat part 4 and the tongue part 5 are sewn at two or more places, the sewing workload will increase, making it difficult to maintain a low manufacturing cost.

[0211] In addition, when the hooking device 1A is manufactured by extrusion molding and only two stitches are made on the flat portion 4 and the tongue portion 5, three stitching grooves 6 are formed on the flat portion 4 and the tongue portion 5 of the hooking device 1A, and a hooking device 1A that can cope with various specifications of sewing machines can be provided.

[0212] In other words, depending on the specifications of the sewing machine itself and the sewing needles used, the positions on the flat portion 4 and the tongue portion 5 where stitching is easy are different. Therefore, by forming a stitching groove 6 on the flat portion 4 and the tongue portion 5 of the hooking device 1A that is greater than or equal to the required number, a hooking device 1A with a wide applicability to sewing equipment can be provided.

[0213] In Figure 1 , taking the case where the hooking device 1A provided in the present embodiment is installed on the right side portion 12 and the left side portion 13 of the refrigerated insulation box 19 respectively, and the tongue portion 5 is provided only on the first side S1 of the flat portion 4 near the front portion 15 as an example, the tongue portion 5 can also be provided on the second side S2 of the flat portion 4 opposite to the first side S1.

[0214] When using the hooking device 1A with the tongue portion 5 only on the first side S1 of the flat portion 4 as shown in Figure 1 , it is necessary to separately prepare the hooking device 1A installed on the right side portion 12 of the refrigerated insulation box 19 and the hooking device 1A installed on the left side portion 13.

[0215] On the other hand, when using the hooking device 1A with the tongue portion 5 on both the first side S1 and the second side S2 of the flat portion 4, not only can the hooking device 1A installed on the right side portion 12 of the refrigerated insulation box 19 and the hooking device 1A installed on the left side portion 13 be used interchangeably, but also a high-performance hooking device 1A with stronger anti-breakage ability can be provided.

[0216] In addition, in the cage car refrigerated insulation box 10A provided in the present embodiment, taking the case where the hooking device 1B is provided on the back portion 11 as an example, a hooking device 1A with the tongue portion 5 on both the first side S1 and the second side S2 of the flat portion 4 can also be installed on the back portion 11.

[0217] In this case, the durability of the cage car refrigerated insulation box 10A provided in the present embodiment can be further improved.

[0218] As Figure 1 shown, if the length L2 of the tongue portion 5 in the hooking device 1A provided in the present embodiment is too small, it is impossible to effectively prevent the deformation of the plates of the refrigerated insulation box 19 that is the installation object of the hooking device 1A, and it is also impossible to effectively prevent the breakage of the hooking device 1A.

[0219] On the other hand, if the length L2 of the tongue portion 5 is too large, when it is installed on the cold storage insulation box 19, the length L1 in the extending direction of the hooking portion 3 must be relatively shortened, and in this way, the strength of the hooking device 1A itself will be reduced.

[0220] In view of the above situation, when the height from the upper edge of the flat plate portion 4 to the upper edge of the hooking portion 3 is H, the length L2 of the tongue plate 5 in the hooking device 1A can be set to satisfy H ≤ L2.

[0221] In addition, when the hooking device 1A provided in this embodiment is a resin molded body, and in order to enable the hooking device 1A to more effectively exert its intended function, the length L1 in the extending direction of the hooking device 3 can be set to at least 1 / 3 of the length of any straight line area of the upper edge 22a of the right wall surface 22 or the upper edge 23a of the left wall surface 23 of the mounting cage car 20 which is the hooking object of the hooking device 1A.

[0222] (Regarding the top surface part)

[0223] As Figure 4 shown, the top surface part 14 of the cold storage insulation box 19 can be provided with one or more thin plate-shaped reinforcements 16, and the reinforcements 16 are arranged to be erected from the right side surface part 12 to the left side surface part 13.

[0224] In this case, when the cage car cold storage insulation box 10A provided in this embodiment is used outdoors, rainwater ponding on the top surface part 14 can be prevented.

[0225] In this case, when the cold storage insulation box 19 is opened and items are put into or taken out of it, rainwater accumulated on the top surface part 14 can be prevented from infiltrating into the cold storage insulation box 19.

[0226] Therefore, in the case where the cold storage insulation box 19 is provided with the reinforcements 16, a cage car cold storage insulation box 10A with higher performance can be provided.

[0227] In addition, the number and arrangement direction of the reinforcement members 16 are not limited to Figure 4 those shown in the figure. In addition, the shape of the reinforcement 16 is not necessarily thin plate-shaped, and it can also be flat plate-shaped.

[0228] In addition, as Figure 2 shown, the upper edge 12a of the right side surface part 12 and the upper edge 13a of the left side surface part 13 in the cold storage insulation box 19 can be gently inclined from the back surface part 11 to the front surface part 15. In other words, the angle θ of the upper edge 12a or the upper edge 13a with respect to the extending direction of the hooking portion 3 of the hooking device 1A can be set within the range of 0 < θ ≤ 10°.

[0229] In this case, especially when it is raining, rainwater easily flows down from the top surface portion 14, so the risk of water accumulation formed on the top surface portion 14 can be further reduced.

[0230] Therefore, a refrigerated insulation box 10A for a cage truck with higher performance can be provided.

[0231] In addition, the top surface portion 14 can also be inclined from the front surface portion 15 towards the back surface portion 11. In this case, the same effect can be achieved.

[0232] (Regarding the internal structure of the refrigerated insulation box)

[0233] The refrigerated insulation box 10A for a cage truck provided in this embodiment is configured such that the mounting cage truck 20 can be folded in a state where it is mounted on the mounting cage truck 20.

[0234] Therefore, the back surface portion 11 of the refrigerated insulation box 10A for a cage truck can be provided with a fixing device such as a hook 17 etc. on its inner side surface, and this fixing device is used to temporarily fix the bottom surface 24 of the mounting cage truck 20 that is lifted vertically upwards.

[0235] In this case, the mounting cage truck 20 provided with the refrigerated insulation box 10A for a cage truck can be folded smoothly.

[0236] Therefore, when the refrigerated insulation box 10A for a cage truck provided in this embodiment is provided with the hook 17, a more convenient refrigerated insulation box for a cage truck can be provided.

[0237] (Regarding the fixing structure for fixing the refrigerated insulation box to the mounting cage truck)

[0238] As a fixing device for fixing the refrigerated insulation box 19 to the mounting cage truck 20, the refrigerated insulation box 10A for a cage truck provided in this embodiment can include, in addition to the combination of the hanging devices 1A and 1B, a fixing structure such as a fixing belt 18 etc. provided vertically below the four corners of the refrigerated insulation box 19.

[0239] The fixing belt 18 is a strip-shaped object with a fixing device such as Velcro on its surface, and is used by winding it around the rod-shaped bodies on the respective side edges of the back wall surface 21, the right wall surface 22, and the left wall surface 23 that constitute the mounting cage truck 20.

[0240] Compared with the case where there is no fixing structure such as the fixing belt 18 etc., when the refrigerated insulation box 10A for a cage truck provided in this embodiment has a fixing structure such as the fixing belt 18 etc., the refrigerated insulation box 19 can be more difficult to fall off from the mounting cage truck 20.

[0241] In addition, when the cage truck refrigerated insulation box 10A provided in this embodiment is equipped with a fixing structure such as a fixing band 18, during the use of the cage truck refrigerated insulation box 10A, it is very difficult to generate an action of pulling the right side surface portion 12 of the refrigerated insulation box 19 away from the right wall surface 22 in the mounting cage truck 20. Similarly, it is also very difficult to generate an action of pulling the left side surface portion 13 of the refrigerated insulation box 19 away from the left wall surface 23 in the mounting cage truck 20.

[0242] This means that at the boundary between the hook portion 3 and the flat plate portion 4 of the hooking device 1A mounted on the refrigerated insulation box 19, it is very difficult to apply a force to pull the hook portion 3 and the flat plate portion 4 apart.

[0243] Therefore, when the cage truck refrigerated insulation box 10A provided in this embodiment is equipped with a fixing structure such as a fixing band 18, the breakage of the hooking device 1A can be more effectively prevented.

[0244] Therefore, a more durable cage truck refrigerated insulation box 10A can be provided.

[0245] In addition, in addition to the illustrated fixing band 18, other fixing structures such as a bindable rope or a swivel hook can be used without any hindrance.

[0246] (Regarding the modification example of the cage truck refrigerated insulation box)

[0247] Figure 6 It is a side view of an important part of the cage truck refrigerated insulation box provided by the modification example of this embodiment.

[0248] Instead of installing one hooking device 1A on each of the right side surface portion 12 and the left side surface portion 13 of the refrigerated insulation box 19 in the aforementioned cage truck refrigerated insulation box 10A, as Figure 6 shown, the cage truck refrigerated insulation box 10B provided by the modification example includes a combination of a hooking device 1A' and a hooking device 1B'. Among them, the length in the extending direction of the hook portion 3 of the hooking device 1A' is L3 (L3 < L1), and the length in the extending direction of the hook portion 3 of the hooking device 1B' is L4 (L4 < L1).

[0249] In Figure 6 it, a case where there is one hooking device 1A' and one hooking device 1B' on each of the right side surface portion 12 and the left side surface portion 13 of the refrigerated insulation box 19 is described as an example, but it may also include a combination of one hooking device 1A' and two or more hooking devices 1B'.

[0250] When manufacturing the hooking device 1A and the hooking device 1B provided in this embodiment by extrusion molding, it is difficult to make the length directions of the strip-shaped hooking device 1A and the hooking device 1B straight with high precision.

[0251] On the other hand, the length of the hooking device 1A' in the extending direction of the hooking part 3 is L3, which is shorter than L1, and the length of the hooking device 1B' in the extending direction of the hooking part 3 is L4, which is shorter than L1, and it is relatively easy to manufacture. Therefore, the manufacturing costs of the hooking devices 1A' and 1B' are lower than those of the hooking devices 1A and 1B.

[0252] Therefore, in the cage truck refrigerated insulation box 10B provided in the modified example, although the number of the hooking devices 1A' and 1B' sutured to the right side portion 12 and the left side portion 13 increases, and the suturing workload also increases, as a result, the manufacturing cost can be made low.

[0253] In addition, in the cage truck refrigerated insulation box 10B provided in the modified example, instead of the hooking device 1B provided on the back portion 11, a plurality of the above-mentioned hooking devices 1B' can be provided.

[0254] In this case, for the same reasons as above, the manufacturing cost of the cage truck refrigerated insulation box 10B provided in the modified example can be made low.

[0255] In addition, the total number of the hooking device 1A' and at least one hooking device 1B' in the cage truck refrigerated insulation box 10B provided in the present embodiment can be any number of two or more, but the larger the total number, the greater the workload required for suturing and the lower the productivity. Therefore, the total number is preferably as small as possible. More preferably, the total number can be in the range of 2 - 4.

[0256] In addition, when the hooking device 1A' and at least one hooking device 1B' are both resin molded bodies, in order to more effectively exert the expected function of the cage truck refrigerated insulation box 10B provided in the present embodiment, the sum L of the length L3 of the hooking part 3 of the hooking device 1A' provided on the right side portion 12 in the extending direction of the hooking part 3 and the length L4 of the hooking part 3 of at least one hooking device 1B' in the extending direction of the hooking part 3 sum can be set to at least 1 / 3 of the length of the straight line area of the upper edge 22a of the right wall surface 22 of the mounting cage truck 20 as its hooking object, and the sum L of the length L3 of the hooking part 3 of the hooking device 1A' provided on the left side portion 13 in the extending direction of the hooking part 3 and the length L4 of the hooking part 3 of at least one hooking device 1B' in the extending direction of the hooking part 3 sum can be set to at least 1 / 3 of the length of the straight line area of the upper edge 23a of the left wall surface 23 of the mounting cage truck 20 as its hooking object.

[0257] Industrial applicability
