Description

[Technical Field]

[0001] The present invention relates to a cart for carrying and transporting luggage. [Background technology]

[0002] The hand truck is a transport vehicle that is pushed or pulled by human power, and is the ancestor of all vehicles. Although material transport technology has evolved, the hand truck remains an indispensable transport tool.

[0003] When transporting boxes with conventional trolleys, the flat plate that carries the weight lacks a stopper device for the boxes, making it easy for the boxes to fall or tip over when the road surface is uneven or curved.In addition, since the loading plate of conventional trolleys is generally an entire plate-like structure, the weight of the entire trolley is large, which indirectly increases the burden on the user when transporting cargo. Furthermore, there is no handle to lift the cart itself, which is inconvenient when there is a step, etc. Furthermore, although various carts are known that allow the handle to be folded down when stored, it is preferable to provide a configuration that is as compact as possible even in the folded down state. Summary of the Invention [Problem to be solved by the invention]

[0004] To provide a cart which can easily transport a load and has improved usability even when not transporting a load. Preferably, in response to the defects of the prior art, a dolly is currently proposed to solve the problem that when the prior art dolly in the background art transports boxes, the flat plate on which the weight is placed lacks a stopper device for the boxes.

[0005] In order to achieve the above object, the present invention proposes and realizes the following techniques. [Means for solving the problem]

[0006] The present invention, which solves the above problem, is a cart equipped with a loading plate on which items are placed, the loading plate having a loading plate body, a lightening hole provided on the surface of the loading plate body, and a groove hook portion to be held by a user, the groove hook portion including a plurality of groove plates provided adjacent to the lightening hole, and the plurality of groove plates being arranged consecutively so as to face each other. The weight reduction holes make the cart lighter, facilitating the transportation of luggage, and the continuously arranged groove plates make it easier to grip, making it easier to move the cart while holding the loading plate body. [Effects of the Invention]

[0007] The present invention, which solves the above-mentioned problems, can provide a cart that can easily transport luggage and has high usability even when not carrying luggage. In addition, compared with the prior art, the overall advantages of the present invention include:

[0008] (1) An attachment groove is installed on the loading plate, and the box is placed into the attachment groove. The attachment groove stops and fixes the side of the box, preventing the box from falling off the loading plate during transportation and increasing the stability of the cart. In addition, by opening a lightening hole at the bottom of the attachment groove and designing the base surface of the loading plate to be lighter, the loading effect of the box can be ensured and the weight of the loading plate and the entire cart can be reduced, achieving a lighter weight and easing the burden on the user.

[0009] (2) A groove hook and a fixed pillar are installed, and after placing the box containing the cargo in the fastening groove, the hooks on both ends of the fixed rope are hooked onto the groove hook or the fixed pillar and clamped. This prevents the fixed rope from coming off the loading plate during transport, preventing the box from falling and improving transport stability. [Brief explanation of the drawings]

[0011] The technical solutions in the embodiments of the present invention will be described below clearly and completely with reference to the drawings, but it is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative work are within the protection scope of the present invention.

[0012] In this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply that such an actual relationship or order exists between these entities or operations. The orientations or positional relationships indicated by the terms "up," "down," "left," "right," "top," etc. are based on the orientations or positional relationships shown in the drawings and are merely for facilitating and simplifying the description of the present invention, and are not intended to indicate or imply that the designated devices or elements must have a particular orientation, be configured, or operate in a particular orientation, and should not be understood as limitations on the present invention. In addition, the word "abbreviated" in the application documents is a concept that means that the shape that follows has been chamfered or rounded, and that the elements that make up the shape have been deformed or changed in length within a range that does not impede the purpose or effect of the configuration.

[0013] Example 1: As shown in Figures 1 to 4, the cart includes a mounting plate 1, a stopper portion installed on the top of the mounting plate 1, the stopper portion including an engagement groove, the bottom of which has a plurality of evenly distributed lightening holes 2 that pass through the mounting plate 1, the engagement groove serving to stop a box placed on the mounting plate 1, the box being engaged within the engagement groove, and a fixing portion installed on the bottom of the mounting plate 1, the fixing portion including a groove hook portion 5 that is attached to a hook at the end of a fixing rope that secures the box.

[0014] An attachment groove is provided on the loading plate 1, and a box is placed into the attachment groove. The four edges of the attachment groove stop and secure the sides of the box, preventing the box from falling off the loading plate 1 during transport and increasing the stability of the cart. Furthermore, a lightening hole 2 is provided at the bottom of the attachment groove, and a lightening design is applied to the base surface of the loading plate 1, ensuring the effectiveness of box placement and further reducing the weight of the loading plate 1 and the entire cart, achieving a lightweight design and easing the burden on the user. A groove hook 5 is provided, and after a box containing cargo is placed in the attachment groove, an elastic fixed rope is used to tie the box to the loading plate 1. The hooks on both ends of the fixed rope are caught on the groove hook 5 to clamp the box, preventing the fixed rope from coming off the loading plate 1 during transport and causing the box to fall off.

[0015] In the dolly of this embodiment, the engaging groove is the first engaging groove 3, and the four peripheries of the loading plate 1 protrude upward to form the first engaging groove 3, which is located in the middle of the loading plate 1. With this arrangement, the first engaging groove 3 is located in the middle of the loading plate 1, so that the force is evenly applied when transporting boxes, reducing the burden on the user.

[0016] In the trolley of this embodiment, a reinforcing rib is installed on the bottom of the support plate 1, and the reinforcing rib includes a plurality of rib plates 4 arranged in a staggered pattern horizontally and vertically. Each of the plurality of rib plates 4 is installed vertically on the support plate 1 and molded integrally, and a uniformly distributed lattice structure is formed between the rib plates 4.

[0017] By installing a reinforcing rib integrally molded at the bottom of the loading plate 1, the loading capacity of the loading plate 1 is ensured, a decrease in the strength of the loading plate 1 due to the installation of the lightening holes 2 is avoided, weight is reduced, and the trolley can load more cargo, improving practicality.

[0018] In the bogie of this embodiment, multiple groove hooking portions 5 are installed, and the multiple groove hooking portions 5 are installed on the edges of the above-mentioned support plate 1 and include multiple groove plates 6 installed at intervals, and notches that can be engaged with hooks are formed between two adjacent groove plates 6.

[0019] A number of grooves 5 are provided at the bottom edge of the support plate 1, and the hooks on both ends of the fixing rope can be easily hooked between the opposing grooves 5, ensuring uniform force on the box and effective fixing. As shown in Figure 3, the groove plate 6 and the rib plate 4 intersect, and the width of the notch between the groove plates 6 is not smaller than the width of the hook on the fixing rope, so that the hook is locked onto the rib plate 4, and the groove plates 6 on both sides act as stoppers for the hook, preventing it from moving and improving fixing stability.

[0020] Preferably, the outer edge of the groove plate 6 is arc-shaped to match the shape of the hook and make it easy to hook the hook, and a groove corresponding to the groove plate 6 is opened on the side of the support plate 1 to further reduce the impact of the support plate 1 on the hook and reduce wear on the fixed rope caused by the edge of the support plate 1.

[0021] In the trolley of this embodiment, the fixed part further includes a fixed post 7 that matches the hook, and the fixed post 7 is installed on both the left and right sides of the groove hook part 5 and extends in a direction away from the loading plate 1, and the height of the fixed post 7 is not smaller than the height of the groove plate 6.

[0022] By installing the fixed posts 7, it is easy to hook the hooks of the fixed ropes, and combined with the grooved portions 5, the grooved portions 5 are preferably installed in the middle of the side edges of the mounting plate 1, and the fixed posts 7 are installed at positions close to both sides of the side edges of the mounting plate 1, making it easy to use the fixed ropes to fix boxes close to the edges of the mounting plate 1, and improving practicality.

[0023] In the trolley of this embodiment, a bracket 10 is fixedly attached to the loading plate 1, and a handle 11 is rotatably connected within the bracket 10, and the side edge of the bracket 10 and the side edge of the loading plate 1 are flush with each other.

[0024] Preferably, the handle 11 is arranged as a two-tiered handle lever structure to facilitate use by workers of different heights.

[0025] In the trolley of this embodiment, the bracket 10 is installed below the above-mentioned mounting plate 1 and includes a bracket main body and an extension plate 12, and multiple extension plates 12 are installed, and the multiple extension plates 12 are installed perpendicular to the bracket main body with a gap between them, and the side of the extension plate 12 and the side of the mounting plate 1 are flush with each other.

[0026] The side edges of bracket 10 are flush with the side edges of the aforementioned support plate 1, making it easy to stand the entire dolly upright after use by folding handle 11, thereby reducing the space occupied by the dolly when idle. Bracket 10 also increases the contact area between the rear end of support plate 1 and the ground, thereby improving the stability of the dolly when upright. Preferably, extension plates 12 are symmetrically installed on both sides of the bracket body, and the side edges of extension plates 12 are flush with the side edges of support plate 1, increasing the contact area between the side of support plate 1 and the ground while preventing the center of the bracket body from contacting the ground, thereby reducing the ground surface requirements for standing the dolly and improving practicality. The center of the bracket body can also accommodate the hook of a fixing rope, which, combined with the groove 5 on the front of support plate 1, enhances the fixing effect for the box.

[0027] In the bogie of this embodiment, the stopper portion further includes a storage groove 13, which can accommodate the handle 11 and is located on both sides of the engagement groove, and a clamp block 14 that stops the handle 11 is installed in the storage groove 13.

[0028] By providing a storage groove 13 and a clamp block 14 to fix the folded handle 11, the handle 11 moves after being folded, preventing the cart from tipping over.

[0029] Example 2: 5 to 7, the bogie of this embodiment uses the structure of Example 1 except for the following structure: The engagement grooves include a second engagement groove 8 and a third engagement groove 9, the second engagement groove 8 is arranged along the length direction of the loading plate 1, the third engagement groove 9 is arranged along the width direction of the loading plate 1, and the second engagement groove 8 and the third engagement groove 9 intersect perpendicularly.

[0030] In order to accommodate a wider range of box sizes and to enhance practicality, second and third engaging grooves 8 and 9 are provided, making it easier to load boxes onto the trolley along the length or width of the loading plate 1.

[0031] In the trolley of this embodiment, the bracket 10 is installed above the loading plate 1, groove hooks 5 are installed on all four sides of the bottom of the loading plate 1, and a damper is installed in the center of the handle 11 to act as a stopper against the box at the top of the loading plate 1.

[0032] In the present invention, unless otherwise clearly specified and limited, the terms "mounting," "installing," "connecting," "fixing," "rotating," etc. should be understood in a broad sense. For example, they may be fixedly connected, detachably connected, integrated, mechanically connected, electrically connected, directly connected, indirectly connected via an intermediate medium, or internal communication between two elements or an interactive relationship between two elements. Unless otherwise clearly limited, those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0033] Although embodiments of the present invention have been shown and described in detail, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0034] <Modification of Example 1> The first embodiment of the present invention may be modified as follows, as shown in Figures 8 to 11. Configurations not mentioned in the modified examples have the same configurations and effects as the first embodiment described above, and the same reference numerals will be used to simplify the description.

[0035] The present invention is a cart equipped with a loading plate 1 on which an item is placed, the loading plate 1 having a loading plate main body 100, a lightening hole 2 provided on the surface of the loading plate main body 100, and a groove hook portion 5 to be held by a user, the groove hook portion 5 including a plurality of groove plates 6 provided adjacent to the lightening hole 2, and the plurality of groove plates 6 being arranged successively so as to face each other.

[0036] The present invention also provides a cart equipped with a loading plate 1 on which an item is placed, the loading plate 1 having a horizontally arranged loading plate body 100 and engagement grooves (3, 8, 9) that protrude in a stepped manner from the upper surface of the loading plate body.

[0037] the handle 11 for controlling the direction of movement of the plate 1; a bracket 10 for rotatably connecting the plate 1 and the handle 11; an extension plate 12 that comes into contact with the ground when the plate 1 is stored; a storage groove 13 provided on the plate 1 and in which at least a portion of the handle 11 is stored when the handle 11 is in the stored state; a clamp block 14 that keeps the handle 11 stored in the storage groove 13; and casters 15 that facilitate movement of the plate 1. The handle 11 is provided so as to be switchable between a use state in which it is erected relative to the placing plate 1 and a storage state in which it is laid down on the placing plate 1.

[0038] The loading plate 1 is a plate material that is approximately rectangular in plan view, and is provided so that various items can be placed on the upper surface. The loading plate 1 has a plate-shaped loading plate main body 100, and in the loading plate main body 100, the side closest to the handle 11 is the rear end side 101, the side opposite to the rear end side 101 is the front end side 102, and the sides connecting the rear end side 101 and the front end side 102 are the side end sides 103. Note that the loading plate 1 is not limited to a rectangular shape and may have various other shapes. The loading plate main body 100 is almost hollow inside due to the lightening holes 2 and rib plates 4, which reduces its weight.

[0039] The lightening holes 2 are holes cut out in the plane of the mounting plate main body 100, and in this embodiment, multiple holes are provided at intervals. The lightening holes 2 are approximately rectangular holes, and the orientation of their short sides coincides with the orientation of the short sides of the mounting plate main body 100, except for adjacent lightening holes 201, which will be described later, making them easier to arrange and increasing their strength. The width of the lightening holes 2 in the direction parallel to the rear end edge 101 is wider the closer they are to the center. This allows for further weight reduction. Furthermore, the lightening hole 2 is formed inside the positions where the first engaging groove 3, the second engaging groove 8 and the third engaging groove 9 are provided, thereby increasing the strength. Furthermore, the lightening holes 2 are provided symmetrically on the left and right sides and at positions that are off the center of the mounting plate main body 100, thereby maintaining strength. In addition, among the lightening holes 2, the adjacent lightening hole 201 adjacent to the storage groove 13 is located closer to the storage groove 13 than the adjacent lightening hole 2 in the direction parallel to the rear end edge 101, making it easy to fasten the lightening hole 2 by hanging a rope or the like thereon.

[0040] The first engaging groove 3 is a protruding portion provided close to the rear edge 101, and restricts the movement of items on the loading plate 1 by forming a step between the protruding portion and the surface on which the lightening holes 2 are provided, from one storage groove 13 to the other storage groove 13. It has a first engaging step portion 300 that protrudes toward the top surface beyond the plane on which the lightening holes 2 are provided, and an engaging slope portion 301 that rises gently from the plane on which the lightening holes 2 are provided. By separating the first engaging groove 3 from the rear end edge 101, interference with the handle 11 is less likely to occur, improving the ability to place articles on the dolly.

[0041] The first attachment step 300 is provided parallel to the rear end edge 101 and is disposed equidistant from both side edges 103. The first attachment step 300 rises substantially perpendicularly from the surface on which the lightening holes 2 are provided, thereby preventing a placed article from falling off the rear end edge 101 due to inertia.

[0042] The inclined engaging surfaces 301 are provided on both sides of the first engaging step 300, and are gently inclined rearward from the vicinity of the first engaging step 300. This allows the article, even if it is a long member, to be held between the first engaging step 300 and the third engaging groove 9 in a state where it is difficult to move.

[0043] The rib plate 4 is a plate material provided perpendicular to the surface on the back side of the mounting plate main body 100 where the lightening holes 2 are provided, and has outer edge ribs 401 provided so as to surround the outer edge of the mounting plate main body 100, and internal ribs 402 provided in a lattice pattern on the inside of the mounting plate main body 100. The thickness of the rib plate 4 is set to be approximately the same as or slightly thicker than the thickness of the mounting plate main body 100, thereby maintaining strength. In addition, the engagement grooves (3, 8, 9) are provided with rib plates 4 along the portions that stand on the top surface side, thereby improving the strength of the steps.

[0044] The outer edge rib 401 is a part that rises on the outer edge of the mounting plate main body 100. The outer edge rib 401 is provided to have approximately the same height overall, but cutouts are provided in the parts facing the parts where the groove hooking part 5 and the fixed column 7 are provided, so that these parts can be seen from the side, thereby enabling them to perform their functions.

[0045] The internal ribs 402 are parts that protrude in a lattice pattern parallel to the width and length directions inside the mounting plate main body 100, and are arranged between the lightening holes 2, thereby improving the strength of the mounting plate main body 100. In addition, screw holes for fixing the casters 15 to multiple locations are provided at predetermined positions at the intersections of the lattice-like internal ribs 402, allowing for connection while maintaining strength by distributing the load. The protruding height of the internal ribs 402 is at least greater than half the short side length of the adjacent lightening holes 2, and is shorter than the short side length of the adjacent lightening holes 2, thereby ensuring strength and reducing weight.

[0046] 10, the groove hooking portion 5 is a portion that is held by the user, and has a side groove hooking portion 501 provided on the side edge 103 and a front groove hooking portion 502 provided on the front edge 102. Both groove hooking portions 5 are provided between the outer edge of the mounting plate main body 100 and the adjacent lightening hole 201, so that the user can insert their fingers into the adjacent lightening hole 201 and grasp the groove hooking portion 5 to hold it.

[0047] The side groove hooking portion 501 is a portion provided at approximately the center of the side edge 103, and is provided so that an imaginary line extending from the center of gravity of the dolly to the side groove hooking portion 501 is approximately parallel to the front edge 102, making it easy to handle when held in the hand. In addition, the side groove hooking portion 501 is provided on the back surface of the storage groove 13, thereby achieving a compact design while maintaining the strength around the groove hooking portion 501.

[0048] The front groove hooking portion 502 is a portion provided at approximately the center of the front edge 102, and is provided so that an imaginary line extending from the center of gravity of the dolly to the front groove hooking portion 502 is parallel to the side edge 103, making it easy to handle when held in the hand. In addition, the front groove hooking portion 502 is provided on the back surface of the second engaging groove 8, which increases the diameter of the gripping portion and makes it easier to grasp. Furthermore, when the handle 11 is in the stored state, it is provided away from the installation portion 1102, which will be described later, making it easier to grasp.

[0049] The grooved plate 6 is a thin plate with a ribbed structure that is actually gripped in the grooved portion 5, and multiple grooved plates 6 are provided in succession. Focusing on one grooved plate 6, it is provided in the shape of a half-moon plate. That is, the grooved plate 6 has a tip portion 601 located at the tip of the protruding direction as seen from the mounting plate main body 100, and arc-shaped portions 602 extending from both sides of the tip portion 601. The grooves 6 are provided perpendicular to the outer edge of the adjacent support plate body 100, and are arranged parallel to each other and at equal intervals. This allows the fingers to fit into the gaps between the grooves 6 when gripping the plate, improving the grip comfort. In addition, increasing the number of protrusions makes it easier to attach various assistive devices. The grooves 6 may be provided so that the entire outer edge, including the tip portion 601, is arc-shaped. In addition, by making the grooves 6 in the groove hook portion 5 out of a flexible material, the spacing between the grooves 6 may be adjustable to some extent, improving the grip comfort to suit the user's fingers.

[0050] The tip portion 601 is a portion that is provided at the tip of the grooved plate 6 and is parallel to the mounting plate body 100. Having a portion that is parallel to the plate in this way improves the performance of the rib and increases the strength of the grooved portion 5. In addition, by increasing the length along which the fingers can follow, the grip is more comfortable. In the side groove hooking portion 501, the strength is further improved by providing the adjacent internal ribs 402 so as to perpendicularly intersect the tip portion 601. The tip portion 601 may be arc-shaped.

[0051] The arc-shaped portion 602 is an arc-shaped portion, for example a circular arc, that connects the tip portion 601 to the outer edge of the support plate main body 100 or the tip portion 601 to the outer periphery of the adjacent cutout hole 201. The former arc-shaped portion 602 connects to the notched portion of the outer edge rib 401 and smoothly continues with the support plate main body 100, improving the grip comfort. In particular, by connecting to the notched portion, the arc-shaped portion 602 is exposed to the outside in side view, making it less likely that the corners of the outer edge rib 401 will come into contact with the hand, improving the grip comfort. Furthermore, the latter arc-shaped portion 602 smoothly connects to the edge that forms the outer periphery of the adjacent cutout hole 201, which is close to the outer edge of the support plate main body 100, improving the grip comfort. In this way, by providing the arc-shaped portion 602 at an angle relative to the tip portion 601, the burden on the joints when the user grips the grip can be reduced.

[0052] The fixed posts 7 are supports for hooking ropes to secure articles on the loading plate 1, and two are provided near each of the front edge 102 and both side edges 103. The fixed posts 7 are provided on both sides of the grooved portions 5 from each side, making it easy to attach articles in various positions. Furthermore, the fixed posts 7 protrude from approximately the center of the lattice formed by the rib plates 4, where no lightening holes 2 are provided, thereby providing a strong support for the fixed posts 7. In addition, the fixed posts 7 are designed to protrude higher from the loading plate main body 100 than all of the other rib plates 4, making it easy to hang ropes and attach them.

[0053] The second engaging groove 8 is a protruding portion of the front edge 102, including the front edge 102, and a recess is formed between the protruding portion and the surface on which the lightening hole 2 is provided, thereby preventing items from moving due to inertia and falling off the cart. The second engaging groove 8 is also formed in a roughly rectangular parallelepiped shape, with both ends spaced apart from the third engaging groove 9. This makes it easier to remove trash that has accumulated on the loading plate 1 or storage groove 13 from between the second engaging groove 8 and the third engaging groove 9, improving usability.

[0054] The third engaging groove 9 is a protruding portion of each side edge 103, including the side edge 103, and a recess is formed between the protruding portion and the surface on which the lightening hole 2 is provided or the storage groove 13, thereby preventing items from moving due to inertia and falling off the cart. The protruding height of the third engaging groove 9 is approximately the same as the protruding height of the first engaging groove 3 and the second engaging groove 8, thereby reducing the thickness when stored and increasing the strength. In addition, the third engaging groove 9 is formed in an approximately rectangular parallelepiped shape and is provided adjacent to and along the storage groove 13, so that its height protects the handle 11 in the stored state.

[0055] 11, bracket 10 is a part that rotatably fixes handle 11, and is provided near rear edge 101. In this embodiment, bracket 10 is provided below the top surface of mounting plate main body 100, and handle 11 fits into a position lower than the height of third engaging groove 9 when stored. The bracket 10 has a bracket main body 1000 that holds the handle 11, a rotating shaft portion 1001 that actually connects the bracket main body 1000 and the handle 11 so that they can rotate, an interference portion 1002 that interferes with the handle 11 in both the use state and the storage state, an operating portion 1003 that allows the position of the interference portion 1002 to be changed, and a path hole 1004 that defines the movement path of the operated interference portion 1002.

[0056] The bracket main body 1000 is disposed near the corner where the rear end edge 101 and the side end edge 103 connect, and is an integral part that extends downward from the inside of the mounting plate main body 100. The bracket main body 1000 is box-shaped, and supports the rotation axis part 1001 and the interference part 1002 so that they are parallel to the rear end edge 101.

[0057] The rotation shaft portion 1001 is a rod member that is provided so as to be perpendicular to the side edge 103 in a plan view, and is provided rotatably inside the bracket body 1000. The rotation shaft portion 1001 is provided at least above the groove hook portion 5 and the storage groove 13, thereby preventing interference with the groove hook portion 5.

[0058] The interference portions 1002 are rods, and two are provided in this embodiment. When the handle 11 is in use, they are arranged so that the handle 11 is sandwiched between the interference portions 1002, thereby interfering with the handle 11 and maintaining the handle 11 in an upright position. When the handle 11 is transitioned to the stored position, one of the interference portions 1002 moves, so that the handle 11 and the interference portion 1002 do not interfere with each other, allowing the handle 11 to rotate in one direction.

[0059] The operating unit 1003 is a component that enables the interference unit 1002 to move along a movement path, and is connected to the interference unit 1002. In this embodiment, the operating unit 1003 is provided to protrude from the upper surface of the mounting plate main body 100, and is configured to be movable downward by stepping on it or the like. The interference unit 1002 that can be operated by the operating unit 1003 penetrates and connects to each bracket main body 1000 and the operating unit 1003, and moves along the path hole 1004 in conjunction with the movement of the operating unit 1003. It is preferable that the operating unit 1003 is biased so that the interference unit 1002 is in an upright position when no force is applied.

[0060] The handle 11 is a pipe material formed in an approximately U-shape, and has two standing portions 1101 that stand upright relative to the mounting plate main body 100 when in an upright state, and a bridge portion 1102 that bridges the standing portions 1101 at their upper ends.

[0061] The erected portion 1101 is fitted into the storage groove 13 in the stored state, and is provided longer than the storage groove 13 to prevent interference between the erected portion 1102 and the mounting plate main body 100. This allows for compact storage.

[0062] Storage groove 13 is a groove provided between the surface on which lightening hole 2 is provided and third engaging groove 9, and is provided so that standing portion 1101 can be stored therein, and is recessed toward the bottom side of the surface on which lightening hole 2 is provided. The shape of the recess is provided to correspond to standing portion 1101, and the distance from the lower end of storage groove 13 to the upper end of third engaging groove 9 is set to be approximately the same as or larger than the diameter of handle 11, allowing for compact storage. Storage groove 13 extends from directly above bracket main body 1000 to the front end of mounting plate main body 100, parallel to third engaging groove 9. Storage groove 13 also has a clamp block 14 inside it that holds handle 11 in a predetermined position.

[0063] The clamp block 14 is a plate member provided inside the storage groove 13 so as to bias it inward. By locking a part of the upper side of the standing portion 1101 in the storage state, the handle 11 can be temporarily fixed in the storage state, thereby increasing stability in the storage state. Furthermore, the clamp block 14 is provided adjacent to the grooved portion 5, but is provided closer to the front edge 102 than the grooved portion 5, which makes it easier to apply a moment and improves the performance of fitting and removal.

[0064] <Modification of Example 2> The second embodiment of the present invention may be modified as follows, as shown in Figures 12 to 15. In the modified examples, the same reference numerals as those in the first or second embodiment including the modified examples described above will be used for the configurations not mentioned, and the description will be simplified.

[0065] In this embodiment, the device comprises a loading plate 1 on which items are placed, a lightening hole 2 provided on the surface of the loading plate 1 to reduce weight, a first fastening groove 3, a second fastening groove 8 and a third fastening groove 9 that protrude from the upper surface of the loading plate 1 to prevent items from falling off, a rib plate 4 that reinforces the area around the lightening hole 2, a groove hooking portion 5 that a user grasps to lift the plate, a groove plate 6 that constitutes the groove hooking portion 5, a fixed post 7 that protrudes to hook a rope or the like, a handle 11 that controls the direction of movement of the loading plate 1, a bracket 10 that rotatably connects the loading plate 1 and the handle 11, an extension plate 12 that comes into contact with the ground when the loading plate 1 is stored, a storage groove 13 provided on the loading plate 1 and in which at least a portion of the handle 11 is stored when the handle 11 is stored, a clamp block 14 that keeps the handle 11 stored in the storage groove 13, and casters 15 that make it easy to move the loading plate 1.

[0066] The lightening holes 2 are holes cut out in the plane of the support plate main body 100, and in this embodiment, multiple holes are provided at intervals. The lightening holes 2 include adjacent lightening holes 201 provided near the side edge 103 and inner lightening holes 202 provided inward of the adjacent lightening holes 201. The adjacent lightening holes 201 include holes provided adjacent to the groove hooking portion 5 and have a generally rectangular shape elongated in the direction of the side edge 103. The inner lightening holes 202 are provided in multiple groups of adjacent rectangular small holes. The small holes are defined by the rib plate 4 and are closely spaced apart. Meanwhile, the groups are spaced apart, resulting in wider spacing and increased strength. By providing the inner lightening holes 202 in this manner, strength can be increased while increasing the lightening area. Furthermore, increasing the number of lightening holes 2 improves the flexibility of attaching ropes and the like. In addition, in this embodiment, friction members 104 having a frictional force greater than that of the surface of the mounting plate 1 are provided between the groups, improving the article holding performance.

[0067] The first engaging groove 3 is a protruding portion that is provided in an approximately straight line from one side of the side edge 103 to the other, and forms a step between the protruding portion and the surface on which the lightening hole 2 is provided, thereby preventing unintentional movement of the placed item.

[0068] The rib plate 4 has outer edge ribs 401 and internal ribs 402. The internal ribs 402 are arranged in a lattice pattern parallel to the length and width directions of the mounting plate 1. In the embodiment, the outer edge rib 401 adjacent to the groove engaging portion 5 is provided so as to cover the groove engaging portion 5 in a side view, thereby increasing the strength. Here, among the internal ribs 402 extending in the longitudinal direction, those that define the small holes may be set to protrude higher from the mounting plate body 100 than the other ribs, thereby maintaining the strength of the ribs that are prone to loads.

[0069] As shown in FIG. 5(a), the groove hooking portion 5 is composed of a plurality of groove plates 6. The outer edge of the groove plates 6 has a tip portion 601 and an arc-shaped portion 602 that are continuous. The protruding height of the groove plates 6 is approximately the same as that of the outer edge rib 401, and the end of the tip portion 601 and the end of the outer edge rib 401 are connected on the same plane. This increases the durability of the outer edge rib 401 and the mounting plate 1. In addition, in this embodiment, the arc-shaped portion 602 is provided on only one side of the tip portion 601, and the tip portion 601 and the portion that forms the outer periphery of the adjacent lightening hole 201 are smoothly connected in an arc, improving the comfort of the grip.

[0070] The second engaging groove 8, which is a step adjacent to and parallel to the front edge 102, and the third engaging groove 9, which is a step adjacent to and parallel to the side edge 103, are provided continuously. More specifically, the second engaging groove 8 and the third engaging groove 9 are formed as steps that form a U-shape along the outer edge in a plan view on the top surface of the loading plate main body 100. A container of a predetermined size can be fitted as an article between the first engaging groove 3, the second engaging groove 8, and the third engaging groove 9, improving transport performance.

[0071] The bracket 10 has two bracket bodies 1000, a rotation shaft portion 1001, an interference portion 1002, an operation portion 1003, and a path hole 1004. In the embodiment, the bracket body 1000 is provided in a U-shape and is fixed to the top surface of the mounting plate body 100 near the rear edge 101 with the open surface facing the top surface.

[0072] Furthermore, the rotating shaft 1001 is provided near the upper end of the bracket body 1000, so that the handle 11 is as inclined as possible when the bracket body 1000 is stored. A plurality of interference portions 1002 are provided on the bracket body 1000, and the handle 11 is positioned between two interference portions 1002 when in use. At least one of the interference portions 1002 is provided operatively so as to use the path hole 1004 as a movement path. Furthermore, each of the operable interference portions 1002 provided on the two bracket bodies 1000 is supported by an operating portion 1003 that operates in conjunction with the interference portion 1002, and the interference portion 1002 moves in response to the up and down movement of the operating portion 1003. In this embodiment, the rotating shaft 1001 and the operating portion 1003 are connected by an elastic member, so that the interference portion 1002 is positioned at the top when not operated.

[0073] The handle 11 has an upright portion 1101 and a bridge portion 1102. In this embodiment, the upright portion 1101 has a bent portion 1103 that is bent midway.

[0074] The bent portion 1103 is a portion that smoothly connects the base portion and the installation portion side portion of the standing portion 1101, extending approximately perpendicular to the mounting plate main body 100 in the use state, and is inclined upward in the direction of the rear end edge 101. The angle of inclination is set to be at least larger than the angle between the mounting plate main body 100 and an imaginary line extending from the rotation shaft portion 1001 to the storage groove 13. As a result, the portion of the bent portion 1103 close to the base portion is fitted into and held by the clamp block 14 in the stored state. In addition, by bringing the installation portion side portion closer to the rear end edge 101, handling is improved.

[0075] The storage groove 13 is a groove provided along the side edge 103, closer to the front edge 102 than the second engagement groove 8, thereby allowing the handle 11 to be stored at a higher position on the mounting plate 1, improving storage performance. In the embodiment, the storage groove 13 is a hole that passes through the mounting plate 1, and is provided at a position corresponding to the bent portion 1103 in the stored state.

[0076] The clamp block 14 is an elastic plate member positioned inside the storage groove 13, and holds the handle 11 by elastically deforming when the handle is in the stored state.

[0077] The following describes in detail a method for carrying out the present invention with reference to the drawings. The present invention is carried out by a user using a dolly. The method for carrying out the present invention is an example, and the method for carrying out the present invention is not limited to this, and the order of the steps may be reversed.

[0078] When changing the dolly from the usage state to the storage state, the user steps on the operating part 1003 to move the interference part 1002 downward, so that the interference part 1002 and the handle 11 do not interfere with each other and the handle 11 can be freely rotated. After that, the user tilts the handle 11, puts the handle 11 into the storage groove 13, and holds it with the clamp block 14 to maintain the storage state.

[0079] When changing the cart from the stored state to the used state, the user removes the handle 11 from the clamp block 14 and rotates it so that it stands upright. At this time, the handle 11 pushes in the interference part 1002, so that the cart can be changed to the used state without operating the operating part 1003.

[0080] When carrying the dolly in the stored state, the user grasps the grooved portion 5. At this time, the grooved plate 6 is provided along the user's fingers, improving the gripping comfort. In addition, the grooved portion 5 is provided in a position that does not interfere with the handle 11, improving the ease of holding.

[0081] When a user places an item on the cart and moves it, the first engaging groove 3, second engaging groove 8, and third engaging groove 9 protrude from the surface, preventing the item from falling off the loading plate 1 even if it moves due to inertia. In addition, by hanging a rope through the fixed posts 7 or the lightening holes 2, the item can be easily held on the loading plate 1.

[0082] In addition, the grooved plates 6 are arranged adjacent to the end edges (102, 103) of the mounting plate body 100 and extend in a direction perpendicular to the end edges (102, 103), so that the fingers can fit between the grooved plates 6, improving the gripping comfort.

[0083] Furthermore, groove plate 6 is provided to protrude from mounting plate body 100, and groove plate 6 has tip portion 601 located at the end in the protruding direction and arc-shaped portion 602 provided at an angle to tip portion 601, which are exposed to the outside, giving it a shape that fits more comfortably in the fingers and improving grip comfort. It also makes it less likely for load to be applied locally.

[0084] Furthermore, the mounting plate main body 100 has rib plates 4 protruding in a grid pattern on the back surface, and the groove hooking portions 5 are arranged between the rib plates 4, thereby reinforcing the groove hooking portions 5. Furthermore, the protruding height of the rib plates 4 from the mounting plate main body 100 is approximately the same as, but slightly larger than, that of the groove hooking portions 5, making it less likely that unintended loads will be applied.

[0085] Furthermore, since the edge of the groove plate 6 is connected to the outer edge of the mounting plate main body 100, the groove plate 6 itself functions as a rib, and further reinforces the outer edge rib 401 of the mounting plate main body 100.

[0086] Also, a handle 11 is provided which is connected to the placing plate 1, and the handle 11 is switchable between an upright state in which it stands up relative to the placing plate 1 and a stored state in which it lies down relative to the placing plate 1, and the handle 11 is provided at a distance from the groove hooking part 5 when in the stored state, so that the user can easily grip the groove hooking part 5 without interfering with the handle 11. In the second embodiment, this effect can be achieved by fitting the bent part 1103 into the storage groove 13.

[0087] It also has a handle 11 connected to the mounting plate 1, and the handle 11 is switchable between an upright state in which it stands up relative to the mounting plate 1 and a stored state in which it is laid down relative to the mounting plate 1. The mounting plate body 100 has a storage groove 13 that stores the handle 11 in the stored state, and the groove hook portion 5 is provided on the back of the storage groove 13, making the configuration compact and reinforcing the structurally weak storage groove 13.

[0088] Furthermore, by providing a plurality of grooved portions 5 on the mounting plate body 100, the user can carry the dolly in various ways.

[0089] In addition, by having a handle 11 that connects to the loading plate 1 and a first engagement groove 3 that is provided close to the connection between the handle 11 and the loading plate 1, as well as a second engagement groove 8 that is provided parallel to the front end edge 102 of the cart and a third engagement groove 9 that is provided parallel to the side end edge 103 of the cart, it is possible to prevent items placed on the loading plate 1 from rolling off due to inertia.

[0090] Furthermore, a rib plate 4 is provided on the back surface of the mounting plate 1 so as to protrude along the engaging grooves (3, 8, 9), so that even if a load is applied to the engaging grooves, the load can be dispersed and strength can be increased.

[0091] In addition, the second engagement groove 8 and the third engagement groove 9 are provided so as to protrude from the end of the loading plate 1, and the second engagement groove 8 and the third engagement groove 9 are provided with a gap therebetween, so that dust and the like that has fallen on the loading plate 1 can be easily collected and discharged through the gap.

[0092] In addition, the second and third engagement grooves 8 and 9 are arranged continuously in a U-shape and are positioned inside the outer edge of the loading plate body 100, so that rectangular parallelepiped objects that correspond to the grooves can be engaged and easily transported.
