Description

[Technical Field]

[0001] The present disclosure relates to precision equipment transport devices. [Background technology]

[0002] Traditionally, precision equipment has been transported mainly by chartered vehicle, which allows the equipment to be transported naked without packaging such as wooden boxes.

[0003] A basket cart is generally used to transport goods (see, for example, Patent Documents 1 to 7). Furthermore, when transporting precision equipment, a technique has been disclosed in which the precision equipment is secured to a pallet with a lashing belt (see, for example, Patent Documents 8 and 9). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-4909 [Patent Document 2] Utility Model Registration No. 3165264 [Patent Document 3] Utility Model Registration No. 3219175 [Patent Document 4] Japanese Patent Application Laid-Open No. 2014-172494 [Patent Document 5] Japanese Patent Application Laid-Open No. 2011-246161 [Patent Document 6] Japanese Patent Application Laid-Open No. 2013-241187 [Patent Document 7] Japanese Patent Application Laid-Open No. 2011-245980 [Patent Document 8] Japanese Patent Application Laid-Open No. 2011-121633 [Patent Document 9] Utility Model Registration No. 3014598 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in recent years, precision equipment has become increasingly miniaturized, and direct shipments from factories to end users have become more common. As a result, the volume of cargo is no longer sufficient to charter a single truck, and chartered transportation poses cost and environmental issues, leading to a desire for consolidated transportation.

[0006] Patent Documents 1 to 6 do not consider how to secure precision equipment to a cart when transporting the equipment using the cart. Patent Document 7 describes a copier as a transported item. However, because the ends of the belt portion 4 are attached to the mooring portions 32b at both ends of the front panel 32, if the precision equipment is narrow, the precision equipment may move between the belt and the front panel. Furthermore, the use of pallets as in Patent Documents 8 and 9 has the problem of making it difficult to secure the precision equipment stably when it is tall. Until now, no technology has been proposed for safely transporting precision equipment on mixed cargo flights at low cost without packaging such as in wooden boxes.

[0007] An object of the present disclosure is to provide a precision instrument transport device that can transport precision instruments safely and inexpensively. [Means for solving the problem]

[0008] The precision equipment transport device according to the present invention comprises a basket cart having a rear frame having a bottom side, a top side, a left side side, and a right side side, a floor plate connected to the bottom side of the rear frame, a left side frame connected to the left side side of the rear frame and extending to the left front side of the rear frame, and a right side frame connected to the right side side of the rear frame and extending to the right front side of the rear frame, one or more first lashing rails that are stretched across the left side side and the right side side of the rear frame and have a plurality of belt holes that are parallel in the stretching direction, and a stretching direction that stretches across the side side of the left side frame on the rear frame side and the side side opposite to the rear frame side of the left side frame. one or more second lashing rails having a plurality of belt loop holes aligned in the direction of the lashing; one or more third lashing rails that are stretched across the side edge of the right frame on the rear frame side and the side edge opposite the rear frame side and have a plurality of belt loop holes aligned in the direction of the lashing; a lashing belt that engages with any of the plurality of belt loop holes provided in at least one of the first lashing rail, the second lashing rail, and the third lashing rail to fasten the precision equipment; and a fastener that fastens both ends of the lashing belt together. The cart has a variable mechanism for varying the height from the surface of the floor board of at least one of the first lashing rail, the second lashing rail, and the third lashing rail. It is characterized by: By having an adjustable mechanism, it can be fixed at an appropriate position depending on the height of the precision equipment being transported.

[0009] In the precision equipment transport device according to the present invention, it is preferable that the cart further includes a front opening provided on a surface facing the rear frame and an auxiliary rail extending across the front opening, so that even if a problem occurs in the fastening of the lashing belts, the auxiliary rail can secure the precision equipment within the cart.

[0011] The precision equipment transporting device according to the present invention preferably further comprises a protective mat to be wrapped around the precision equipment to be transported, thereby enabling the precision equipment to be transported more safely.

[0012] In the precision equipment transport device according to the present invention, the curing mat preferably has a structure in which a plurality of columns or cylinders are arranged in parallel, and the generatrix of the adjacent columns or cylinders is connected to each other, so that the curing mat can be more closely attached to the precision equipment depending on the width and depth of the precision equipment.

[0013] In the precision equipment transport device according to the present invention, it is preferable that the curing mat has a generally rectangular shape in a plan view, with a horizontal direction in which the mat is wrapped around the precision equipment and a vertical direction perpendicular to the horizontal direction, and the length in the vertical direction is longer than the distance between the lower end edge of the first lashing rail and the surface of the floor board. A lashing belt can be wrapped around the curing mat. [Effects of the Invention]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0016] Next, the present invention will be described in detail with reference to the embodiments, but the present invention is not limited to these descriptions. Various modifications of the embodiments may be made as long as the effects of the present invention are achieved.

[0017] FIG. 1 is a schematic diagram showing an example of a precision equipment transporting device according to this embodiment. The precision equipment transport device 1 according to this embodiment includes a basket cart 100 having a rear frame 10 having a bottom side 11, a top side 12, a left side side 13, and a right side side 14, a floor board 20 connected to the bottom side 11 of the rear frame 10, a left side frame 30 connected to the left side 13 of the rear frame 10 and extending forward on the left side of the rear frame 10, and a right side frame 40 connected to the right side 14 of the rear frame 10 and extending forward on the right side of the rear frame 10, one or more first lashing rails 51 (51A, 51B) that are stretched across the left side 13 and right side 14 of the rear frame 10 and have a plurality of belt loop holes p1 that are aligned in the stretching direction, and one or more first lashing rails 51 (51A, 51B) that are stretched across the side 31 of the left side frame 30 on the rear frame 10 side and the side 32 opposite to the rear frame 10 side and have a plurality of belt loop holes p2 that are aligned in the stretching direction. The lashing rail 60 (60A, 60B) includes two or more second lashing rails 52 (52A, 52B), one or more third lashing rails 53 (53A, 53B) that are stretched across the side edge 41 on the rear frame 10 side of the right frame 40 and the side edge 42 opposite the rear frame 10 side and have a plurality of belt loop holes p3 that are parallel to the stretching direction, a lashing belt 60 (60A, 60B) that engages with any of the plurality of belt loop holes p1, p2, p3 provided in at least one of the first lashing rail 51 (51A, 51B), the second lashing rail 52 (52A, 52B), and the third lashing rail 53 (53A, 53B) to securely fasten the precision equipment, and a fastener 61 that fastens both ends of the lashing belt 60 (60A, 60B) together.

[0018] The precision equipment transporting device 1 is a basket carrier for transporting precision equipment 200 naked and unpackaged without packaging such as in a wooden crate, wooden box, or cardboard box, using a mixed load service such as a route service. The precision equipment 200 is not particularly limited as long as it can be secured to a basket cart, but it is preferable that it is a small precision equipment weighing, for example, 500 kg or less, such as a server rack, ATM, or multifunction printer. Small precision equipment does not have a cargo volume that is suitable for chartering an entire truck, and transporting it on a chartered truck has cost and environmental issues, but the precision equipment transporting device 1 according to this embodiment allows it to be transported on a mixed load service.

[0019] As shown in FIG. 1 , the cart 100 is a transport cart having a rectangular floor panel 20, and three of its four sides, excluding the front opening 2, are surrounded by a rear frame 10, a left frame 30, and a right frame 40. The rear frame 10, the left frame 30, and the right frame 40 are each a rectangular frame, and panels 15, 35, and 45 may be provided to cover part or all of the frame. In this specification, the designations of left and right are for convenience of explanation and do not limit the invention. When the cart 100 is viewed from the rear frame 10 side toward the front opening 2, the frame provided on the side facing the left side is referred to as the left frame 30, and the frame provided on the side facing the right side is referred to as the right frame 40.

[0020] As shown in Fig. 1, the lashing rails 51, 52, and 53 are rails for attaching a lashing belt 60, and have a plurality of belt-passing holes p1, p2, and p3 arranged in parallel in the longitudinal direction of the rails. In this embodiment, the lashing rails hung across the rear frame 10 are called first lashing rails 51 (51A, 51B), the lashing rails hung across the left frame 30 are called second lashing rails 52 (52A, 52B), and the lashing rails hung across the right frame 40 are called third lashing rails 53 (53A, 53B). Fig. 1 shows, as an example, a configuration in which two lashing rails each of 51, 52, and 53 are provided in parallel, but the present invention is not limited to this, and there may be one lashing rail each of 51, 52, and 53, or three or more lashing rails each. The first lashing rails 51 (51A, 51B), the second lashing rails 52 (52A, 52B) and the third lashing rails 53 (53A, 53B) are preferably provided at the same height position.

[0021] As shown in FIG. 1, the lashing belt 60 (60A, 60B) is a belt for securing luggage (precision equipment 200 in FIG. 1), and is passed through any of the belt holes p1, p2, p3 of any of the lashing rails 51, 52, 53 to secure the precision equipment.

[0022] The fastener 61 is, for example, a buckle.

[0023] In the precision instrument transport device 1 according to this embodiment, it is preferable that the basket cart 100 further has casters 22 provided on the rear surface of the floor board 20.

[0024] FIG. 2 is a schematic diagram showing a folded state of the basket cart of the precision instrument transport device according to this embodiment. The basket cart 100 may be foldable as shown in FIG. 2. Next, an example of a foldable basket cart 100 will be described. The basket cart 100 has a left frame 30 and a right frame 40 each having a mounting piece 46 (shown in FIG. 2) on which a floor panel is placed, and a spring stopper 47 (shown in FIG. 1) for holding down the surface of the floor panel 20. The mounting piece 46 is a plate surface extending from the lower end of the right frame 40. A mounting piece is also provided at the lower end of the left frame 30, similar to the lower end of the right frame 40. The spring stopper 47 is a rod-shaped member having one end rotatably fixed to the right frame 40 and the other end being a free end. The free end is placed on the upper surface of the floor panel 20 to fix the floor panel 20, and the free end is removed from the upper surface of the floor panel 20 to release the fixation of the floor panel 20. In Fig. 2, as an example, the spring stopper 47 is shown provided on the right frame 40, but the present invention is not limited thereto, and the spring stopper 47 may be provided on the left frame 30. When the cart 100 is in use, the floor panel 20 is configured to be sandwiched between the mounting piece 46 (shown in Fig. 2) and the spring stopper 47 and locked, as shown in Fig. 1. When the cart 100 is not in use, the floor panel 20 is released from the locked state by the spring stopper 47, and the floor panel 20 is rotated around the lower edge 11 of the rear frame 10 as an axis and overlapped on the rear frame 10, as shown in Fig. 2. At this time, the floor panel 20 may be fixed with a first fixing device (not shown). The first fixing device may be, for example, a U-shaped member attached to the panel 15 of the rear frame 10 or the first lashing rail 51, with one end of the U-shaped member rotatably fixed and rotated to fix the floorboard 20 superimposed on the rear frame 10. Furthermore, the left frame 30 is rotated around the left side edge 13 of the rear frame 10 as an axis to be superimposed on the floorboard 20 superimposed on the rear frame 10. At this time, the left frame 30 may be fixed with a second fixing device (not shown). The second fixing device may be, for example, a chain connecting the left frame 30 and the rear frame 10. Furthermore, while Figure 2 shows an example in which the left side frame 30 is folded, this embodiment is not limited to this, and the right side frame 40 may be folded, specifically, the right side frame 40 may be configured to be freely rotatable around the right side edge 14 of the back frame 10 as an axis, and to be superimposed on the floor board 20 superimposed on the back frame 10 and fixed with a second fixing device.By folding only either the left side frame 30 or the right side frame 40, the basket cart 100 can stand on its own in the folded state.

[0025] In the precision instrument transport device 1 according to this embodiment, as shown in FIG. 1, the cart 100 preferably further includes a front opening 2 provided on the surface facing the rear frame 10, and auxiliary rails 54 (54A, 54B) that cross the front opening 2. Even if a problem occurs in securing the precision instrument with the lashing belts 60 (60A, 60B), the auxiliary rails 54 (54A, 54B) can secure the precision instrument within the cart 100. While FIG. 1 shows an example in which two auxiliary rails 54 (54A, 54B) are provided in parallel, the present invention is not limited to this, and the number of auxiliary rails 54 (54A, 54B) may be one or three or more. The auxiliary rails 54 (54A, 54B) are preferably provided at the same height as the first lashing rails 51 (51A, 51B), the second lashing rails 52 (52A, 52B), and the third lashing rails 53 (53A, 53B). The lashing rails 51, 52, 53 and the auxiliary rails 54 cross the four sides of the cart 100, thereby increasing the strength of the cart 100.

[0026] The auxiliary rails 54 (54A, 54B) are removed from the front opening 2 when loading or unloading the precision equipment 200 or when folding the basket cart 100. It is preferable that the removed auxiliary rails 54 (54A, 54B) be configured so that they can be stored by engaging engagement pieces (not shown) provided at both ends of the auxiliary rails 54 (54A, 54B) with storage grooves (not shown) provided on the left side 13 and right side 14 of the rear frame 10. The engagement pieces are hook-shaped portions that protrude from both ends of the auxiliary rails 54 (54A, 54B). The storage grooves are recesses or holes that can engage the engagement pieces. By engaging the engagement pieces (not shown) of the auxiliary rails 54 (54A, 54B) with the storage grooves (not shown) of the rear frame 10, the auxiliary rails 54 (54A, 54B) are suspended across the rear frame 10 in the same manner as the first lashing rails 51 (51A, 51B).

[0027] In the precision equipment transport device 1 according to this embodiment, the cart 100 preferably has a variable mechanism (not shown) for varying the height of at least one of the first lashing rails 51 (51A, 51B), the second lashing rails 52 (52A, 52B), and the third lashing rails 53 (53A, 53B) from the surface of the floorboard 20. This allows the rails to be fixed at an appropriate position depending on the height of the precision equipment to be transported. The variable mechanism may be, for example, a plurality of rail engagement grooves arranged in parallel in the vertical direction on the sides of the rear frame 10, the left frame 30, or the right frame 40 along which the lashing rails 51, 52, and 53 are suspended. The height of the lashing rails 51, 52, and 53 can be varied by engaging both ends of the lashing rails 51, 52, and 53 with the rail engagement grooves at any height. The present invention is not limited to this mechanism, and any known height-adjusting mechanism may be employed. Similarly to the lashing rails 51, 52, and 53, the auxiliary rails 54 (54A and 54B) may also be configured so that the height from the surface of the floorboard 20 is variable.

[0028] As shown in Fig. 1, the precision instrument transporting device 1 according to this embodiment preferably further includes a protective mat 70 to be wrapped around the precision instrument 200 to be transported. This allows for safer transport of the precision instrument 200. The protective mat 70 is a sheet-like member that protects the outer surface of the precision instrument 200.

[0029] In the precision instrument transport device 1 according to this embodiment, the curing mat 70 preferably has a structure in which a plurality of parallel pillars 71 are arranged in parallel, with the generatrix of adjacent pillars 71 being connected to each other, as shown in Fig. 1. The curing mat 70 can be brought into closer contact with the precision instrument 200 depending on the width and depth of the precision instrument. The pillars 71 may be hollow cylinders.

[0030] In the precision instrument transport device 1 according to this embodiment, the protective mat 70 has a generally rectangular shape in plan view, with a horizontal direction in which the protective mat 70 is wrapped around the precision instrument 200 and a vertical direction perpendicular to the horizontal direction. The vertical length is preferably longer than the distance between the lower end edge of the first lashing rail 51 (51A, 51B) and the surface of the floorboard 20. This allows the lashing belt 60 (60A, 60B) to be wrapped around the protective mat 70, as shown in FIG. 1 . When there are two or more first lashing rails 51 (51A, 51B), the vertical length of the protective mat 70 is preferably longer than the distance between the lower end edge of the uppermost rail 51A and the surface of the floorboard 20. This allows the lashing belt 60 (60A, 60B) to be wrapped around the protective mat 70 for all of the first lashing rails 51 (51A, 51B).

[0031] Furthermore, it is preferable that the vertical length of the protective mat 70 is longer than the distance between the lower edge of the auxiliary rail 54 (54A, 54B) and the surface of the floorboard. Even if a problem occurs in the fastening with the lashing belts 60 (60A, 60B), the protective mat 70 comes into contact with the auxiliary rail 54 (54A, 54B), thereby preventing damage to the precision equipment 200.

[0032] In the precision instrument transport device 1 according to this embodiment, the cart 100 preferably further includes a tension member 80 that is suspended across the upper edge of the front opening 2. The tension member 80 is a rod-shaped member. By providing the tension member 80, the upper end of the left side frame 30 and the upper end of the right side frame 40 of the cart 100 are fixed together, thereby further increasing the strength of the side surfaces of the cart 100. The tension member 80 has a fixing protrusion (not shown) and a fixing string 81 at both ends, and the top of the side edge 32 of the left frame 30 opposite the back frame 10 side and the top of the side edge 42 of the right frame 40 opposite the back frame 10 side each have a fixing recess (not shown), and it is preferable that the tension member 80 be fixed to the upper edge of the front opening 2 by engaging the fixing protrusion with the fixing recess and tying the fixing string 81 to the side edge 32 of the left frame 30 and the side edge 42 of the right frame 40. The fixing protrusion is a protrusion that extends in a direction intersecting the longitudinal direction of the tension member 80. The fixing recess is a recess that is large enough to allow the fixing protrusion to be inserted. The fixing string 81 is a string-like member, one end of which is fixed to the tension member 80 and the other end of which is detachably fixed to the side edge 32 of the left frame 30 and the side edge 42 of the right frame 40 .

[0033] When the basket cart 100 is folded, the tension member 80 is removed from the upper edge of the front opening 2. The removed tension member 80 is preferably configured to be stored above the upper side 12 of the rear frame 10 by engaging the fixing protrusions of the tension member 80 with storage recesses (not shown) provided at the top of the left side 13 and the top of the right side 14 of the rear frame 10.

[0034] In the precision equipment transport device 1 according to this embodiment, the floor plate 20 has fork guides 23 for inserting and removing the claws of a forklift, as shown in FIGS. 1 and 2, and the fork guides 23 preferably have claw insertion openings 23a (shown in FIG. 2) that open on the rear frame 10 side. The fork guides 23 are, for example, cylindrical or gutter-shaped members, and are attached to the rear surface of the floor plate 20. The insertion openings 23a are openings on one side of the cylindrical or gutter-shaped member. In the precision equipment transport device 1 according to this embodiment, when the precision equipment 200 is fastened, the center of gravity is shifted to the rear frame 10 side. Therefore, when the basket cart 100 is transported by a forklift, more stable transportation can be achieved by inserting the claws of the forklift from the rear frame 10 side.

[0035] Fig. 3 is a schematic diagram showing a state in which a slope is attached to the precision instrument transport device according to this embodiment. In the precision instrument transport device 1 according to this embodiment, the floor plate 20 preferably has a slope fixing portion 24a (shown in Fig. 1) for fixing the slope 24, as shown in Fig. 3. The slope fixing portion 24a is, for example, a groove provided on the side surface of the floor plate 20 on the front opening 2 side as shown in Fig. 1. The slope 24 can be fixed to the cart 100 by inserting a protrusion (not shown) of the slope 24 into this slope fixing portion 24a.

[0036] 4 and 5 are schematic diagrams of the precision equipment transport device according to this embodiment, seen from above, illustrating an example of how the precision equipment is secured. As shown in FIGS. 4 and 5, the precision equipment 200 is preferably secured by pressing one of its sides against the rear frame 10. When the precision equipment 200 has a relatively small width, it can be secured using only the first lashing rail 51, as shown in FIG. 4. When the precision equipment 200 has a relatively large width, it can be secured using the second lashing rail 52 and the third lashing rail 53, as shown in FIG. 5. As shown in FIGS. 4 and 5, the precision equipment transport device 1 according to this embodiment can securely secure the precision equipment 200 for safe transport by appropriately selecting the lashing rails 51, 52, and 53 with which the lashing belt 60 engages, depending on the size or shape of the precision equipment 200 to be secured. The lashing rails 51, 52, and 53 used for securing the precision equipment 200 are not limited to the examples shown in FIGS. 4 and 5. The lashing rails 51, 52, 53 used for lashing may be changed depending on the size and / or shape of the precision equipment 200, and may be, for example, a configuration using the first lashing rail 51 and the second lashing rail 52, a configuration using the first lashing rail 51 and the third lashing rail 53, a configuration using only the second lashing rail 52, a configuration using only the third lashing rail 53, or a configuration using the first lashing rail 51, the second lashing rail 52, and the third lashing rail 53. In addition, the number of precision equipment 200 placed on one cart 100 may be one, or two or more.

[0037] When selecting the lashing rails 51, 52, 53 to engage with the lashing belt 60, it is preferable to select lashing rails 51, 52, 53 that can secure the precision instrument 200 so that the angle θ between the side of the precision instrument 200 and the lashing belt 60 is approximately 45° when either side of the precision instrument 200 is abutted against the rear frame 10. By setting θ to approximately 45°, the load on the precision instrument 200 is small and the lashing belt 60 is less likely to loosen, so the precision instrument 200 can be more reliably protected. θ is preferably 35 to 55°, and more preferably 40 to 50°.
