Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described conventional technology, the characters or figures displayed on the mat may disappear with the use of the handcart. This is because the mat inevitably wears out by repeatedly loading and unloading articles. In this document, it is stated that the disappearance of the display can be prevented by coloring the entire thickness of the display part in the main body of the mat. However, this makes the manufacture of the mat complicated. Also, the display written by the user of the handcart on the mat cannot be prevented from disappearing.

[0005] The disclosed technology has been made to solve the problems of the above-described conventional technology. That is, the problem to be solved is to provide a trolley that has a function of preventing articles from sliding and in which the information displayed on the placement surface is difficult to disappear.

Means for Solving the Problems

[0006] A trolley in one aspect of the disclosed technology has an upper surface and a lower surface, and comprises a base plate on which an article is placed, and wheels provided on the lower surface of the base plate, wherein the upper surface is provided with a reference area, anti-slip members provided locally at multiple locations and protruding upward from the reference area, and an information display area recessed downward from the reference area, and the anti-slip members are It is mounted in a recess that is lower than the information display area. The anti-slip members are arranged such that at least one virtual line drawn connecting them passes through the information display area.

[0007] In the trolley described above, the articles placed on the top surface of the base plate rest primarily on the reference area and the anti-slip members. The friction of the anti-slip members suppresses lateral sliding of the articles, and the difference in height between the reference area and the information display area suppresses wear of the information display area due to friction with the articles. Therefore, the information displayed in the information display area is less likely to disappear. The arrangement of the anti-slip members such that a dotted line drawn connecting them passes through the information display area provides anti-slip and wear-suppressing effects in most cases.

[0008] In the trolley according to the above embodiment, it is even preferable that the anti-slip members are arranged such that at least one of the imaginary lines drawn connecting the anti-slip members, which is the shortest distance, passes through the information display area. In this configuration, even relatively small items can be placed on the base plate in a way that provides anti-slip and wear-inhibiting effects.

[0009] In any of the above embodiments of the trolley, it is preferable that the anti-slip members are arranged such that an annular polyline, formed by a combination of multiple imaginary lines drawn connecting the anti-slip members, surrounds the information display area. In this configuration, even relatively large items can be placed on the base plate while maintaining anti-slip and wear-inhibiting effects. In this case, another anti-slip member may be located on an imaginary line drawn connecting the anti-slip members. This configuration allows for the arrangement of items of various sizes.

[0010] In any of the above embodiments, the trolley or base plate has a shape having a pair of long sides and a pair of short sides in a plan view, and the information display area has a shape in which the dimension in the direction parallel to the long sides is longer than the dimension in the direction parallel to the short sides, and a connecting part is provided on one of the pair of short sides and a connected part is provided on the other, and the trolleys are configured to be connected to each other by the connecting part and the connected part, and it is preferable that the information display areas are arranged in a row when the trolleys are connected to each other by the connecting part and the connected part. In this case, the multiple information display areas can be used as a whole in their connected row arrangement.

[0011] The trolley in any of the above embodiments may further have a base plate that, in plan view, has a shape having a pair of long sides and a pair of short sides, and has a first handle portion provided between the connecting portion and the information display area on the base plate, and a second handle portion provided between the connected portion and the information display area on the base plate, and at least a part of the information display area, the first handle portion, the second handle portion, the connecting portion, and the connected portion may be arranged such that at least a part of them is included within the long central portion when the base plate is divided into a first long side portion, a long central portion, and a second long side portion by two imaginary lines in a direction parallel to the long sides. In this configuration, when a user places their hands on the first handle portion or the second handle portion and lifts the trolley, the information display area is not hidden by the user's arms or body.

[0012] The trolley in any of the above embodiments further has a handle portion provided between one of the anti-slip members on the base plate and its edge, the anti-slip members are arranged such that at least one of the shortest distance imaginary lines drawn connecting the anti-slip members passes through the information display area, the handle portion is arranged to overlap with the line extended from the shortest distance imaginary line drawn connecting the anti-slip members that passes through the information display area, and the information display area and the handle portion are arranged such that at least a part of them is included within the central portion when the base plate is divided into a first side portion, a central portion, and a second side portion by two imaginary lines parallel to the shortest distance imaginary line. Even in this configuration, when a user places their hand on the handle portion and lifts the trolley, the information display area is not hidden by the user's arm or body. [Effects of the Invention]

Embodiments for Carrying out the Invention

[0015] Hereinafter, embodiments embodying the disclosed technology will be described in detail while referring to the accompanying drawings. This embodiment applies the disclosed technology to the trolley 1 shown in FIGS. 1 to 3. The trolley 1 of this embodiment is obtained by attaching wheels 3 to a tabletop 2 that appears to be substantially rectangular when viewed from above. FIG. 2 shows the back side of the trolley 1 turned over. The tabletop 2 is a plate-like member for placing an article on its upper surface. The wheels 3 are provided at the four corners of the lower surface of the tabletop 2.

[0016] As shown in Figure 1, the upper surface of the base plate 2 is provided with anti-slip members 4 (6 locations), an information display area 5 (1 location), handles 6 (4 locations), and wheel storage areas 7 (4 locations). The anti-slip members 4 are friction materials that prevent items placed on the base plate 2 from sliding. The information display area 5 is an area for displaying information that the user can visually recognize. The handles 6 are shaped for the user to lift the empty trolley 1 by hand. The wheel storage areas 7 are shaped for storing the wheels 3 in the stacked state described later. The part of the upper surface of the base plate 2 that is not one of the anti-slip members 4, information display area 5, handles 6, or wheel storage areas 7 is called the reference area 8.

[0017] The base plate 2, in a plan view as shown in Figure 3, has a shape having a pair of long sides 9 and a pair of short sides 10. A connecting part 11 is provided on one of the pair of short sides 10 on the base plate 2. A connected part 12 is provided on the other of the pair of short sides 10. The connecting part 11 and the connected part 12 are structures for connecting multiple trolleys 1 as shown in Figures 4 and 5. A connecting rod 13 is provided on the connecting part 11 (Figures 1 and 2), and a stopper hole 14 is formed on the connected part 12. The mounting angle of the connecting rod 13 to the base plate 2 is variable, and two trolleys 1 are connected by inserting the insertion part 15 at the tip into the stopper hole 14 of the other trolley 1. In the configuration shown in Figure 3, the connecting rod 13 is removed. In the connection of trolleys 1 by the connecting part 11 and the connected part 12, there is a certain degree of freedom in the angle between the trolleys 1. Figure 5 shows a state where there is a certain angle between the bogies 1 while maintaining the connection.

[0018] Figure 6 shows the cross-sectional structure of the base plate 2. This cross-sectional view is from position AA in Figure 3. The top and bottom surfaces of the base plate 2 are the levels indicated by arrows B and C in Figure 6. The top surface B is, of course, the mounting surface. As shown in Figure 2, numerous ribs are provided on the back side of the base plate 2, and there are not many plate-like portions that cover a considerable area. However, it is possible to assume a hypothetical surface stretched at the level of the top of the ribs on the back side (the level of arrow C), which is referred to as the bottom surface in this disclosed technology. The wheel 3 is omitted in Figure 6.

[0019] In Figure 6, the level of the upper surface B of the base plate 2 shows the anti-slip member 4, information display area 5, handle 6, and reference area 8, which are the components provided on the upper surface B of the base plate 2 as described above. The left half of Figure 6 is shown enlarged in Figure 7.

[0020] The anti-slip member 4 is described below. As shown in Figure 7, a recess 16 is formed on the upper surface B of the base plate 2. The anti-slip member 4 is a flexible member fitted into the recess 16. The anti-slip member 4 is provided so as to protrude above the reference area 8. However, the amount of protrusion is very small, at most a few millimeters. This is the same for all anti-slip members 4 provided on the upper surface B of the base plate 2.

[0021] The information display area 5 is described below. The information display area 5 is a part of the upper surface B of the base plate 2, and is recessed below the reference area 8. However, the recess is very slight, at most a few millimeters. Users can write letters, figures, etc., in the information display area 5 using some kind of writing instrument. The display written in the information display area 5 is information that the user can recognize visually. Alternatively, information can be displayed by printing letters, figures, etc., on the information display area 5, or by the user attaching a sheet material with letters, figures, etc., displayed on it. Alternatively, the information display area 5 may have some kind of color pattern applied to it from the beginning to display information.

[0022] Let's describe the handle portion 6. In this embodiment, the handle portion 6 is a through hole extending from the upper surface B to the lower surface C of the base plate 2. In this embodiment, the base plate 2 is provided with a finger-grip projection 17 that protrudes from the side of the through hole of the handle portion 6. The finger-grip projection 17 is provided on the upper surface B side, protruding from the long side 9 of the base plate 2. Below the finger-grip projection 17 is a finger-insertion space 18. In this embodiment of the trolley 1, this shape of the handle portion 6 allows the user to easily lift the trolley 1 with one hand. The user can lift the trolley 1 by inserting their fingertips into the handle portion 6 and gripping the finger-grip projection 17. At that time, the user's fingertips are in the finger-insertion space 18. The same applies to the handle portion 6 located closer to the short side 10 in Figure 3. In that case, the finger-grip projection 17 is provided protruding from the short side 10 of the base plate 2.

[0023] The wheel storage section 7 shown in Figure 1, etc., is a recessed area from the upper surface B of the base plate 2. However, the amount of recess is considerably larger than the amount of recess of the information display area 5. The size of the wheel storage section 7 is sufficient to accommodate the wheels 3. The position of the wheel storage section 7 coincides with the position of the wheels 3 on the underside. In the stacked configuration of multiple trolleys 1 shown in Figure 8, the lower ends of the wheels 3 of the upper trolley 1 are stored in the wheel storage section 7 of the lower trolley 1.

[0024] The trolley 1 in this configuration, as described above, is intended to move items placed on the upper surface B of the base plate 2. Movement is basically done manually. The trolley 1 in this configuration has the following advantages due to the anti-slip member 4 and information display area 5 on the upper surface B of the base plate 2.

[0025] Firstly, the anti-slip member 4 provides an anti-slip effect. When the anti-slip member 4 is placed under an item, the anti-slip member 4 under the item is slightly compressed vertically due to the weight of the item. As a result, the anti-slip member 4 and the underside of the item are in close contact. In this state, the coefficient of friction between the anti-slip member 4 and the item is large, making it difficult for the item to slide sideways on the upper surface B.

[0026] Secondly, there is a protective effect on the information display area 5. This means that the information displayed in the information display area 5 is less likely to fade. This is because there is little friction between the information display area 5 and the item placed on it. The item placed on the top surface B will mainly rest on the anti-slip member 4, or on the reference area 8 and the anti-slip member 4. Therefore, the item does not come into much contact with the information display area 5, which is recessed from the reference area 8. As a result, the wear on the information display area 5 is reduced. The anti-slip action of the anti-slip member 4 also contributes to the protection of the information display area 5, as it reduces sliding of the item on the top surface B.

[0027] It cannot be denied that the degree to which the anti-slip effect and the protective effect of the information display area 5 are exhibited varies depending on the size of the item placed on it. However, when the primary use of the trolley 1 is for business purposes, the size of the item placed on it is often fairly constant. When the size of the item to be placed on it is fixed, the arrangement of each component within the upper surface B can be determined in the design of the trolley 1 to match that size. This makes it possible to manufacture a trolley 1 that exhibits an anti-slip effect and protective effect with a high probability for items of that size. The following explains the concept of arranging each component within the upper surface B.

[0028] First, the most basic arrangement will be explained with reference to Figure 9. In the example in Figure 9, the arrangement of the anti-slip member 4, the information display area 5, and the handle 6 is the same as that shown in Figure 3. However, in Figure 9, each anti-slip member 4 is distinguished by a separate reference numeral. Figure 9 also shows a virtual line L1, which is a line segment drawn connecting anti-slip member 42 and anti-slip member 45. Anti-slip members 42 and 45 are the two anti-slip members located in the center of the six anti-slip members in Figure 9 in a direction parallel to the long side 9. With respect to the information display area 5, anti-slip member 42 is located above the figure and anti-slip member 45 is located below the figure.

[0029] In the example in Figure 9, the virtual line L1 passes through the information display area 5. In the example in Figure 9, there are six anti-slip members, so it is possible to consider virtual lines other than virtual line L1 as connecting the anti-slip members. Some of these virtual lines pass through the information display area 5, while others do not. The example in Figure 9 shows that the anti-slip members are arranged such that at least one virtual line drawn connecting the anti-slip members passes through the information display area 5.

[0030] With this arrangement of anti-slip members, the following can be said about the trolley 1 in relation to the items placed on it. Firstly, when an item larger than the short-length size (vertical direction in Figure 9) of the information display area 5 is placed on it, the item will straddle both the upper and lower reference areas 8 in Figure 9. Part of the item is located above the information display area 5, but it does not come into contact with the information display area 5. This is because the information display area 5 is recessed compared to the reference area 8. As a result, wear of the information display area 5 by the item is suppressed. Furthermore, if the item is placed so that it is stepping on both the anti-slip member 42 and the anti-slip member 45, the anti-slip effect of the anti-slip members can also be obtained. The area P1 in Figure 10 is an example of the area occupied on the base plate 2 by the above item.

[0031] The imaginary line L1 in Figure 9 is one of the shortest imaginary lines that can be drawn between the anti-slip members in the same figure. The same applies to the imaginary line L2 in the arrangement example in Figure 11. The example in Figure 11 is the same as the example in Figure 9, but with the number of anti-slip members reduced to three. The imaginary line L2 in Figure 11 is a line segment drawn connecting the central anti-slip member 42 on one long side 9 and the end anti-slip member 46 on the other long side 9. These are arrangements of anti-slip members, and are examples of arrangements such that at least one of the shortest imaginary lines drawn between the anti-slip members passes through the information display area 5.

[0032] In these arrangement examples, if an item is placed in a position that covers the virtual line L1 or virtual line L2, a portion of the information display area 5 will be covered by the item. Even in this state, the information display area 5 is protected by the difference in height between the reference area 8 and the information display area 5. If the item is stepping on the anti-slip member, the anti-slip effect of the anti-slip member is also obtained.

[0033] In the arrangement example shown in Figure 12, the information display area 5 is divided into two parts: information display area 51 and information display area 52. Anti-slip members are provided in six locations, as in the example in Figure 9. In this example, by sequentially connecting imaginary lines that link the two anti-slip members, a ring-shaped polyline L3 can be constructed that surrounds the information display areas 51 and 52. This arrangement example shows the arrangement of anti-slip members, where a ring-shaped polyline L3, formed by a combination of multiple imaginary lines drawn connecting the anti-slip members, surrounds the information display areas 51 and 52.

[0034] In the example in Figure 12, if a large item is placed that covers the entire annular polyline L3, the entire information display area 51 and information display area 52 will be covered by the item. Area P2 in Figure 13 is an example of the area occupied on the base plate 2 by such a large item. Therefore, even when a large item is placed, the effects of protecting the information display area and preventing the item from sliding can be obtained. In this example, a part of the annular polyline L3 and the imaginary line L1 can also be considered as an annular polyline that encloses only one of the information display area 51 or information display area 52. Therefore, the same effect can be obtained even when an item of a size that covers only one of the information display area 51 or information display area 52 but not the other is placed. Area P3 in Figure 13 is an example of the area occupied on the base plate 2 by an item of such size.

[0035] The ability to accommodate both larger and smaller items is due to the anti-slip members 42 and 45 shown in Figure 12. Anti-slip member 42 is another anti-slip member that lies on a virtual line drawn connecting anti-slip member 41 and anti-slip member 43. Similarly, anti-slip member 45 lies on a virtual line connecting anti-slip member 44 and anti-slip member 46. The presence of anti-slip members 42 and 45 allows for greater flexibility in how the virtual lines are drawn and how the annular polyline is constructed.

[0036] The arrangement example in Figure 12 also satisfies the aforementioned condition that at least one virtual line drawn connecting the anti-slip members passes through the information display area. This is because if the virtual line L2 shown in Figure 11 is drawn in Figure 12, that virtual line L2 passes through the information display area 52. Furthermore, if the entire area encompassing information display area 51, information display area 52, and the area between them is considered as a single information display area 5, then the virtual line L1 passes through the information display area 5.

[0037] The arrangement example in Figure 14 is one in which the information display area 51 and the information display area 52 are divided unequally, and the number of anti-slip members is further increased. In this arrangement example, by appropriately selecting the anti-slip members 40 to 49, it is possible to draw virtual lines and annular polylines that satisfy the aforementioned conditions for both the information display area 51 and the information display area 52. Therefore, even in the example in Figure 14, the effect of protecting the information display area and preventing the sliding of items can be obtained for items of various sizes.

[0038] On the base plate 2, the arrangement of the handle portion 6 ensures excellent visibility of the information display area 5 to third parties when the user lifts the trolley 1 with one hand while it is unloaded. This will be explained with reference to Figures 15 and 16. In Figures 15 and 16, the arrangement of the anti-slip member 4, the information display area 5, and the handle portion 6 is the same as shown in Figure 9 or Figure 12. However, in Figures 15 and 16, each handle portion 6 is distinguished by a separate reference numeral. With a few exceptions, the anti-slip member 4 is not individually distinguished, as in Figure 3.

[0039] Figure 15 shows the configurations shown in Figure 9, plus virtual lines L4 and L5. Virtual lines L4 and L5 are lines drawn parallel to the long side 9 and divide the base plate 2 into three parts: the long central part M0, the first long side part M1, and the second long side part M2. The long central part M0 is the region between virtual lines L4 and L5 and is the central part when the base plate 2 is divided into three parts in the direction of the short side 10. The first long side part M1 and the second long side part M2 are the regions outside of virtual lines L4 and L5 and are regions along the long side 9.

[0040] As shown in Figure 15, when the base plate 2 is divided by virtual lines L4 and L5, at least a portion of each of the following is included in the long central part M0: the information display area 5, the first handle portion 61, the second handle portion 62, the connecting portion 11, and the connected portion 12. The first handle portion 61 is the one of the four handle portions 6 located between the connecting portion 11 and the information display area 5. The second handle portion 62 is the one of the four handle portions 6 located between the connected portion 12 and the information display area 5.

[0041] This arrangement in relation to virtual lines L4 and L5 is advantageous when the unloaded trolley 1 is lifted by hand using the first handle portion 61 or the second handle portion 62. When the user lifts the trolley 1 by placing their hand on the first handle portion 61 from the top surface B side, the lifted trolley 1 is in an upright position with the shorter side 10, where the connecting portion 11 is located, as the top surface. As a result, the information display area 5, the second handle portion 62, and the connected portion 12 are all located below the first handle portion 61. Also, the user's body is positioned on the underside (bottom surface C) side of the lifted trolley 1. Therefore, the information display area 5 is not hidden by the user's arm or body, and is easily visible to third parties. Even when the user lifts the trolley 1 by placing their hand on the second handle portion 62, although the orientation is reversed, the information display area 5 is still easily visible to third parties.

[0042] The positions for drawing virtual lines L4 and L5 here only need to satisfy the following conditions. 1. The center of the shorter side 10 of the base plate 2 is included in the longer central part M0. 2. The base plate 2 must have a first long side portion M1 and a second long side portion M2 at both ends in the direction of the short side 10. More specifically, in Figure 15, the vertical centers of the information display area 5, the first handle portion 61, and the second handle portion 62 should be enclosed by the elongated central portion M0. It does not matter whether the anti-slip member 4 is enclosed by the elongated central portion M0 or by the first elongated side portion M1 or the second elongated side portion M2. The handle portions 63 and 64 are better enclosed by the first elongated side portion M1 or the second elongated side portion M2.

[0043] Figure 16 shows the configurations shown in Figure 9, plus virtual lines L1, L6, and L7. In Figure 16, virtual line L1 is shown extended vertically compared to Figure 9. Virtual lines L6 and L7 are lines drawn parallel to the short side 10 and divide the base plate 2 into three parts: the central part N0, the first side part N1, and the second side part N2. The central part N0 is the region between virtual lines L6 and L7, and is the central part when the base plate 2 is divided into three parts in the direction of the long side 9. The first side part N1 and the second side part N2 are the regions outside of virtual lines L6 and L7, and are regions along the short side 10.

[0044] As shown in Figure 16, when the base plate 2 is divided by virtual lines L6 and L7, at least a portion of the information display area 5, the third grip portion 63, and the fourth grip portion 64 are included in the central portion N0. The third grip portion 63 and the fourth grip portion 64 are the four grip portions 6 that are located between the long side 9 and the information display area 5. In Figure 16, the third grip portion 63 and the fourth grip portion 64 are positioned so as to overlap with lines that extend the virtual line L1 upwards or downwards. In other words, the third grip portion 63 and the fourth grip portion 64 are positioned so as to overlap with lines that extend the shortest distance virtual line L1 drawn connecting the anti-slip members 4 that passes through the information display area 5.

[0045] This arrangement in relation to virtual lines L6 and L7 is advantageous when the unloaded trolley 1 is lifted by hand using the third handle portion 63 or the fourth handle portion 64. When the user lifts the trolley 1 by placing their hands on the third handle portion 63 or the fourth handle portion 64 from the top surface B side, the lifted trolley 1 is in an upright position with one of its long sides 9 becoming the top surface. As a result, the information display area 5 is located below the third handle portion 63 or the fourth handle portion 64 that the user places their hands on. Also, as mentioned above, the underside (bottom surface C) of the lifted trolley 1 faces the user's body. Therefore, the information display area 5 is not hidden by the user's arms or body, and is easily visible to third parties.

[0046] The positions for drawing virtual lines L6 and L7 here only need to satisfy the following conditions. 1. The center of the long side 9 of the base plate 2 is included in the central part N0. 2. The first side portion N1 and the second side portion N2 must be present at both ends of the long side 9 of the base plate 2. More specifically, in Figure 16, the center in the left-right direction of the information display area 5, the third handle portion 63, and the fourth handle portion 64 should be enclosed by the central portion N0. The anti-slip member 4 may be enclosed by the central portion N0, the first side portion N1, or the second side portion N2. The handle portions 61 and 62 should preferably be enclosed by the first side portion N1 or the second side portion N2.

[0047] The shape of the information display area 5 is described below. The information display area 5 shown in Figure 3, etc., is formed such that the dimension in the direction parallel to the long side 9 is longer than the dimension in the direction parallel to the short side 10. For this reason, it appears horizontally elongated in Figure 3. This shape is suitable for displaying text strings, etc. When viewed in the connected state shown in Figure 4, the information display areas 5 of each connected trolley 1 are arranged in a row. As a result, the overall display area, when all the information display areas 5 are combined, is quite long. Even when there is a certain angle between the trolleys 1 as shown in Figure 5, the arrangement of the information display areas 5 in a row can still be recognized. It is possible to display information that identifies each individual trolley 1 in each information display area 5, or to display different information in each information display area 5 so that the entire row has a single meaning.

[0048] Even when the information display area 5 is divided as shown in Figures 12 to 14, when the information display area 51 and information display area 52 are viewed as a whole, the dimension in the direction parallel to the long side 9 is longer than the dimension in the direction parallel to the short side 10. Even with such a shape, the state in which the information display areas 5 are arranged in a row when connected can be recognized. It is also possible to mix a trolley 1 in which the information display area 5 is divided with a trolley 1 in which the information display area 5 is not divided and connect them. In that case as well, the state in which the information display areas 5 are arranged in a row when connected can be recognized.

[0049] The virtual lines and annular polylines in the above explanation are drawn virtually to illustrate the arrangement of each component of the base plate 2. It is not necessary for the actual trolley 1 to have virtual lines or annular polylines displayed on it. The material of the base plate 2 is mainly resin, but it is not limited to resin; it may also be metal or wood. If resin is used, it is desirable that it be harder than the resin of the anti-slip material. Recommended resins for the anti-slip material are soft synthetic resins, thermoplastic elastomers, sulfur rubber, etc., which are highly elastic and have excellent wear resistance.

[0050] As described in detail above, according to this embodiment, the base plate 2 of the trolley 1 is provided with an information display area 5 recessed from the reference area 8 and an anti-slip member 4 protruding from the reference area 8. The arrangement of these members is given the various features described above. As a result, a trolley 1 is realized that has an anti-slip function for the items placed on it, while the information displayed in the information display area 5 is less likely to disappear.

[0051] This embodiment is merely illustrative and does not limit the disclosed technology in any way. Therefore, the disclosed technology can naturally be improved and modified in various ways without departing from its essence. For example, the number and arrangement pattern of the information display area 5 and the anti-slip members 4 are not limited to the illustrated example and may be other patterns. The configuration of the connecting part 11 and the connected part 12 is not limited to a configuration using the connecting rod 13 and may be other configurations.

[0052] The handle portion 6 is not a mandatory component. Even if handle portions 6 are provided, there are not necessarily four of them. The shape of the handle portion 6 does not have to be a through hole. It may be a closed hole with an open top B side but a closed bottom C side. However, even with a closed hole, it is preferable to have a drain hole. The shape of the finger rest protrusion 17 and the finger insertion space 18 below it is also not mandatory. The shape of the recess in the wheel storage portion 7 is also not mandatory. The wheels 3 may be foldable or detachable. In addition to the illustrated configuration, there may also be a push bar. The push bar can be foldable, but it is desirable that it be stored below the top B when folded. The plan view shape of the information display area 5 is shown as roughly rectangular, but it is not limited to this shape. For example, it may be a square, other polygons, a circle, an ellipse, etc. Arrangements of these shapes are also acceptable. For polygons, the corners may be rounded. [Explanation of Symbols]
