  Hereinafter, the cart of an embodiment is explained with reference to drawings. The trolley includes a flat trolley, a hand trolley, and the like. Hereinafter, the trolley will be described as an example.

(First embodiment)
FIG. 1 is a plan view of a carriage in the first embodiment. The cart 1 of the embodiment includes a base plate 10, casters 20 attached to the lower surface (first main surface) of the base plate 10, and a seat 40 disposed on the upper surface (second main surface) of the base plate 10. Prepare.

  The base plate 10 is formed with a certain thickness using wood, metal material, or the like. The base plate 10 is formed in a rectangular shape in plan view. An oval through hole 14 is formed near the center of the long side of the base plate 10. An operator can carry the carriage 1 by putting his hand in the through hole 14.

The casters 20 are attached to the four corners of the base plate 10 equally with respect to the center point P of the base plate 10. The center point P of the base plate 10 is, for example, the center of gravity of the base plate 10.
FIG. 2 is a side view of the caster of the carriage in the first embodiment. The caster 20 is attached to the lower surface 10 b of the base plate 10. The caster 20 includes an attachment portion 22, a wheel support portion 32, and a wheel 36.

  The attachment portion 22 is disposed on the lower surface 10 b of the base plate 10. The attachment portion 22 is fixed to the base plate 10 by a fastening member 24. As shown in FIG. 1, the attachment portion 22 is formed in a quadrangular shape in plan view. The fastening members 24 are disposed at the four corners of the attachment portion 22.

As shown in FIG. 2, the wheel support portion 32 is disposed below the attachment portion 22. The wheel support portion 32 is attached to the attachment portion 22 so as to be rotatable. The wheel support portion 32 can rotate around a rotation shaft 30 parallel to the vertical direction. The wheel support portion 32 supports the wheel shaft 34 in a rotatable manner. The wheel shaft 34 is disposed at a predetermined distance from the rotation shaft 30 so as not to intersect the rotation shaft 30. Thus, the caster 20 functions as a free wheel whose direction of the wheels 36 automatically changes according to the traveling direction of the carriage 1. The caster 20 is attached at a position that does not protrude from the base plate 10 even if the direction of the wheel 36 changes.
The cart 1 employs a free wheel for all casters 20. In addition, a free wheel may be employ | adopted for two casters among the four casters 20, and the fixed vehicle by which the direction of the wheel was fixed to the remaining two casters may be employ | adopted.

The sheet 40 is disposed on the upper surface 10 t of the base plate 10. The sheet 40 is formed of an elastic material having a high friction coefficient such as a rubber material. The color of the sheet 40 is different from the color of the base plate 10. For example, when the base plate 10 is made of wood, a red sheet 40 is used.
As shown in FIG. 1, the sheet 40 is formed in a polygon that is equal to the center point P of the base plate 10 in plan view. In other words, the sheet 40 is formed in a polygon that is point-symmetric with respect to the center point P of the base plate 10. The sheet 40 of the embodiment is formed in a quadrangle (rectangle) in plan view. That is, the sheet 40 has a long side 44L and a short side 44S. The sheet 40 functions as a first display unit that displays the rectangular outline R. The sheet 40 is line symmetric with respect to the center line in the long side direction of the base plate, and is also line symmetric with respect to the center line in the short side direction of the base plate.

FIG. 3 is a plan view showing a first usage example of the carriage in the first embodiment. The first usage example is a case where one piece of luggage 2 is carried by one carriage 1. The luggage 2 in this case is mounted up to the size of the seat 40 so that the end portion of the base plate 10 protrudes outside the luggage 2. When the size of the load 2 is smaller than the seat 40, the load 2 is mounted so that the seat 40 protrudes evenly from the lower side of the load 2 in plan view.
The sheet 40 displays a rectangular outline R that is equal to the center point P of the base plate 10. Therefore, if the luggage 2 is mounted so that the seats 40 protrude evenly from the outer periphery of the luggage 2, the luggage is mounted at the center of the carriage 1. Therefore, the luggage 2 can be mounted at an appropriate position of the carriage 1.

By the way, when the carriage 1 is loaded with the luggage 2 and is transported, the carriage 1 receives an impact or the vibration of the carriage 1 when the carriage 1 gets over a protrusion or a step or the like. There may be deviation. If the luggage 2 is not mounted at an appropriate position of the carriage 1 before transportation, the position of the luggage may be shifted, and the carriage 1 may be detached from the lower side of the luggage 2 and the luggage 2 may fall from the carriage 1. .
On the other hand, the cart 1 of the embodiment can mount the luggage 2 at an appropriate position as described above. Therefore, even if the position of the luggage 2 is shifted during transportation, the possibility that the carriage 1 is detached from the lower side of the luggage 2 is reduced. Therefore, it is possible to prevent the luggage 2 from falling from the carriage 1.

  The sheet 40 of the embodiment is formed of an elastic material. Since the elastic material has a high coefficient of friction, even if the carriage 1 vibrates while the luggage 2 is being transported, the position of the luggage 2 on the base plate 10 can be prevented from shifting. Thereby, the fall of the luggage | load 2 can be prevented more reliably.

  The color of the sheet 40 of the embodiment is different from the color of the base plate 10. Therefore, the operator and supervisor of the luggage transport can easily confirm whether the sheet 40 protrudes evenly from the lower side of the luggage 2.

  FIG. 4 is a plan view showing a second usage example of the carriage in the first embodiment. The second usage example is a case where one large luggage 4 is transported by two carriages 1 and 1. In this case, the two carriages 1 and 1 are arranged in the short side direction of the base plate 10 so that the long sides of both are adjacent to each other. Then, the luggage 4 is mounted so as to be passed over the two carriages 1 and 1. The end of the load 4 is matched with the long side of the seat 40. The width of the luggage 4 is set to the length of the long side of the seat 40. Then, the luggage 4 is transported in the short side direction of the base plate 10. Thereby, the luggage | load 4 can be mounted and conveyed in the center of the two trolley | bogies 1 and 1 with respect to the conveyance direction.

  FIG. 5 is a plan view showing a third usage example of the carriage in the first embodiment. The third usage example is a case where one elongated baggage 6 is transported by two carriages 1 and 1. In this case, the baggage 6 is mounted so that the seat 40 protrudes evenly from the end of the baggage 6 in the width direction. As shown in FIG. 5, when the opposite sides 44f and 44g of the seat 40 protrude from the end in the width direction of the load 6, the distance Wf from the load 6 to the side 44f and the distance Wg from the load 6 to the side 44g However, the luggage 6 is mounted so as to be even. Thereby, the luggage | load 6 is mounted in the center of the two trolley | bogies 1 and 1 with respect to a conveyance direction. Further, even if the position of the luggage 6 is shifted during transportation, the possibility that the carriage 1 is detached from the lower side of the luggage 6 is reduced. Therefore, it is possible to prevent the luggage 6 from falling from the carriage 1.

  FIG. 6 is a plan view of the carriage in the first modification of the first embodiment. In the cart 1 of the first embodiment shown in FIG. 1, the seat 40 is disposed on the upper surface of the base plate 10. On the other hand, in the bogie 101 of the first modified example shown in FIG. 6, the outline line 140 is disposed on the upper surface of the base plate 10. In this first modified example, detailed description of portions having the same configuration as in the first embodiment will be omitted.

  The outline line 140 is formed by attaching a tape or the like to the upper surface of the base plate 10. The color of the outline line 140 is different from the color of the base plate 10. For example, when the base plate 10 is made of wood, a white outline line 140 is employed. The outline line 140 is formed in a rectangular shape that is uniform with respect to the center point P of the base plate 10 in plan view. Thereby, the outline line 140 functions as a first display unit that displays a rectangular outline R.

  When loading a load on the cart 101 of the first modification, the load is loaded so that the distance from the outer periphery of the load to the outer shape line 140 is equal. Thereby, the effect similar to 1st Embodiment is acquired. That is, a load can be mounted at an appropriate position in the center of the carriage 101. Further, even if the position of the load is shifted during transportation, the possibility that the carriage 101 is detached from the lower side of the load is reduced. Therefore, it is possible to prevent the luggage from falling.

  FIG. 7 is a plan view of the carriage in the second modification of the first embodiment. In the cart 1 of the first embodiment shown in FIG. 1, the seat 40 is formed uniformly. On the other hand, in the cart 1b of the 2nd modification shown in FIG. 7, the sheet | seat 40b is divided into the striped pattern (ladder shape). In the second modified example, detailed description of portions having the same configuration as in the first embodiment will be omitted.

  The outer shape of the sheet 40b of the second modified example is formed in the same rectangle as the sheet 40 of the first embodiment. The sheet 40b includes a plurality of small regions 82. The plurality of small regions 82 each have a strip-shaped outer shape, and are arranged side by side in the long side direction of the sheet 40b. The plurality of small regions 82 are arranged symmetrically with respect to the center line in the long side direction of the sheet 40b. The widths of the plurality of small regions 82 may be equal or unequal. The colors of the plurality of small areas 82 are set so that the colors of the adjacent small areas 82 are different. The colors of the plurality of small regions 82 may all be different, or every other small region 82 may be the same color. As a result, the sheet 40b is divided into colors in a striped pattern. The small area 82 may be divided into a ladder shape by displaying only the outline.

  The same effect as that of the first embodiment can be obtained by the cart 1b of the second modification. In particular, in the second modified example, since the sheet 40b is divided into a striped pattern (ladder shape), it can be easily confirmed whether the sheet 40b protrudes uniformly from the outer periphery of the load. Thereby, a load can be mounted at an appropriate position in the center of the carriage 1b.

  FIG. 8 is a plan view of the carriage in the third modified example of the first embodiment. In the cart 1c of the third modified example shown in FIG. 8, the seat 40c is divided into a checkered pattern (lattice pattern). In the third modified example, detailed description of portions having the same configuration as in the first embodiment is omitted.

  The outer shape of the sheet 40c of the third modification is formed in the same rectangle as the sheet 40 of the first embodiment. The sheet 40c includes a plurality of small regions 83. The plurality of small regions 83 each have a quadrangular (square) outer shape, and are arranged side by side in the long side direction and the short side direction of the sheet 40c. The colors of the plurality of small areas 83 are set so that the colors of the adjacent small areas 83 are different. The colors of the plurality of small areas 83 may all be different, or every other small area 83 may be the same color. Accordingly, the sheet 40c is divided into colors in a checkered pattern. The small area 83 may be divided into a grid pattern by displaying only the outline.

  The same effect as that of the first embodiment can be obtained with the cart 1c of the third modification. In particular, in the third modified example, since the sheet 40c is divided into a checkered pattern (lattice pattern), it can be easily confirmed whether the sheet 40c protrudes evenly from the outer periphery of the luggage. Thereby, a load can be mounted at an appropriate position in the center of the carriage 1c.

(Second Embodiment)
FIG. 9 is a plan view of a carriage in the second embodiment. The carriage 201 of the second embodiment is different from the first embodiment in that it includes a central line 250 that bisects the rectangular seat 40. In the second embodiment, detailed description of portions having the same configuration as in the first embodiment is omitted.

  The center line 250 is formed by attaching a tape or the like to the upper surface of the sheet 40. The color of the center line 250 is different from the color of the sheet 40. For example, when the sheet 40 is red, the white center line 250 is employed.

  The center line 250 includes a first center line 250j and a second center line 250k. The first center line 250j extends in parallel with the short side 44S through the center of the long side 44L of the sheet 40. Thereby, the first center line 250j bisects the rectangle of the sheet 40 in the direction of the long side 44L. The second center line 250k extends through the center of the short side 44S of the sheet 40 in parallel with the long side 44L. Thus, the second center line 250k bisects the rectangle of the sheet 40 in the direction of the short side 44S.

  FIG. 10 is a plan view showing an example of use of the carriage in the second embodiment. The luggage 202 includes a low-rigidity intermediate member 206 between a pair of highly rigid side plates 204. When transporting the luggage 202, the low-rigidity intermediate member 206 cannot be placed on the carriage 201. For this reason, the pair of high-rigidity side plates 204 are placed on the carriages 201 and 201 in a state where they are erected. When the side plate 204 is placed in an upright state, the sheet 40 greatly protrudes from the lower side of the side plate 204, so it is difficult to check whether the sheet 40 protrudes evenly from the side plate 204.

  On the other hand, in the usage example shown in FIG. 10, the side plate 204 of the luggage 202 is placed along the second center line 250k. The second center line 250k displays a bisector that bisects the rectangular sheet 40 in the direction of the short side 44S. Therefore, the side plate 204 is disposed at the center of the sheet 40 in the direction of the short side 44S. Thereby, a load can be mounted at an appropriate position in the center of the carriage 201. Moreover, even if the position of the side plate 204 is shifted during transportation, the possibility that the carriage 201 is detached from the lower side of the side plate 204 is reduced. Therefore, the luggage 202 including the side plate 204 can be prevented from falling.

  Although the cart of the embodiment described above includes four casters, the number of casters is not limited to four.

  The cart of the above-described embodiment includes a polygonal sheet that is uniform with respect to the center point of the base plate. However, the first display unit that displays a polygonal outline is not limited thereto. For example, the polygonal coating may be applied to the upper surface of the base plate. It is desirable to employ a paint that exhibits an elastic force after drying (a material having a high coefficient of friction) after drying.

  According to at least one embodiment described above, by having the first display unit that displays a uniform polygonal contour line with respect to the center point of the base plate, the sheet can be evenly projected from the outer periphery of the luggage. It can be loaded with luggage. Thereby, a load can be mounted at an appropriate position in the center of the carriage. Further, even if the position of the load is shifted during transportation, the possibility that the load will be removed from above the first display unit is reduced. Therefore, it is possible to prevent the luggage from falling from the carriage.

  Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the device. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the invention described in the claims of the utility model registration and the equivalent scope thereof.
