Summary of the Invention

Problems to be Solved by the Invention

[0004] In the flat plate carrier described in Patent Document 1, when an object needs to be leaned against or laid down, it is necessary to lift the object and load and unload it on the inclined loading platform, which places a burden on the operator.

[0005] Therefore, an object of the present disclosure is to reduce the burden associated with switching between the leaned and laid-down states of an object.

Means for Solving the Problems

[0006] The holding device according to the present disclosure includes a base, a holding member on which an object is placed, and a support member installed on the base and capable of supporting the holding member in a state inclined with respect to the base. When the support member does not support the holding member, the holding member is stacked on the base.

Effects of the Invention

[0007] According to this disclosure, by supporting the holding member with the support member tilted relative to the base, the object can be held upright. If the support member does not support the holding member, the object can be held lying down by stacking the holding member on the base, thereby reducing the burden required to switch between the upright and lying down positions of the object.

Mode for Carrying Out the Invention

[0009] Embodiment 1. ***Description of the Configuration*** In the embodiments and the drawings, the same elements or corresponding elements are denoted by the same reference numerals. The description of the elements denoted by the same reference numerals as the described elements is omitted or simplified as appropriate. The arrows in the drawings mainly indicate the flow of the process.

[0010] The object in this embodiment assumes a flat cable that sends an elevator control signal.

[0011] In this embodiment, when the support member supports the holding member, it means that the support member supports the holding member in a state where the holding member is inclined with respect to the base. Leaning the holding member means supporting the holding member on the support member. When the support member does not support the holding member, it means that the holding member overlaps the base. Folding the carriage means not supporting the holding member on the support member. Laying down the holding member means not supporting the holding member on the support member.

[0012] In this embodiment, when the holding member overlaps the base, it means the case where the holding member is in surface contact with the base, the case where the holding member and the base are parallel, and the case where the base and the support member are in surface contact and the support member and the holding member are in surface contact.

[0013] The carriage 101 using the holding device 100 of Embodiment 1 will be described based on FIGS. 1 to 15. <<Carriage 101>> FIG. 1 is a front view of the carriage 101. In the following description, with respect to the carriage 101, the directions of “up”, “down”, “left”, and “right” are specified as indicated by the arrows in FIG. 1 as a principle. “Up” corresponds to vertically upward. “Down” corresponds to vertically downward. “Left” corresponds to the left direction for an operator facing the carriage 101. “Right” corresponds to the right direction for an operator facing the carriage 101. Note that the front side of the carriage 101 is taken as the “front side” in FIG. 1. Also, the side of the surface facing the front of the carriage 101 is taken as the “back side” in FIG. 1.

[0014] As shown in FIG. 1, the carriage 101 includes a holding device 100 and wheels 70. The wheels 70 are attached to the bottom surface of the base 10 in plurality.

[0015] <<Holding Device 100>> The holding device 100 includes a base 10, a holding member 20, a support member 30, and a fixing portion 60. FIG. 2 is a left side view of the carriage 101. The base 10 and the support member 30 are connected at a support member fulcrum 42. Also, the holding member 20 and the support member 30 are connected at a holding member fulcrum 41. The support member fulcrum 42 and the holding member fulcrum 41 are the axes of the hinges.

[0016] <<Fixing Portion 60>> As shown in FIG. 1, the fixing portion 60 includes a fixing member 61, a base groove 62, a holding member groove 63, a base fixing groove 64, and a holding member fixing groove 65. The fixing portion 60 fixes the inclination of the holding member 20. The base groove 62 is provided in the base 10. The retaining member groove 63 is provided in the retaining member 20. The base fixing groove 64 and the retaining member fixing groove 65 are provided in the support member 30. The fixing member 61 is an L-shaped sheet metal. Two fixing members 61 are used. The other fixing member 61 is installed so that its end fits into the base groove 62 and the base fixing groove 64. The other fixing member 61 is installed so that its end fits into the retaining member groove 63 and the retaining member fixing groove 65.

[0017] <<Base 10>> The configuration of the base 10 will be explained using Figures 2, 3, and 4. Figure 3 is a front view of the base 10. The base 10 is a metal plate with a width of w1 and a depth of d1.

[0018] Figure 4 is a left side view of the base 10. As shown in Figure 4, a recessed base storage section 80 is provided on the upper surface of the base 10. The base storage section 80 can accommodate the support member 30. The width of the base storage section 80 is w1, the depth is d2, and the height is h1. The width of the base storage section 80 should be longer than the width w4 of the support member 30, which will be described later.

[0019] A base groove 62 is formed on the upper surface of the base 10. The base groove 62 is a groove with a width of w2. In this implementation, the height of the base groove 62 is lower than h1. In other words, the base groove 62 is formed to be shallower than the base storage section 80. Therefore, the base groove 62 is formed in pairs on the rear and front sides of the trolley 101.

[0020] <<Holding member 20>> The configuration of the retaining member 20 will be explained using Figures 2 and 5. Figure 5 is a front view of the retaining member 20. The holding member 20 is a metal plate for supporting an object. The retaining member 20 has a width of w3 and a depth of d1. The width w3 of the retaining member 20 is greater than the width w1 of the base 10.

[0021] A receiving member 21 is attached to one end of the holding member 20. The receiving member 21 is a plate with a depth of d1. The receiving member 21 and the holding member 20 are connected by a hinge (not shown). Furthermore, a locking mechanism is provided to fix the angle between the receiving member 21 and the holding member 20.

[0022] A resin rotating shaft 50 is rotatably mounted on the upper surface of the holding member 20. Specifically, a bearing (not shown) is provided inside the holding member 20, and the bearing rotatably supports the rotating shaft 50. The rotating shaft 50 is located in the center of the holding member 20. The configuration may allow the position of the rotation axis 50 to be moved in the left-right direction depending on the size of the object placed on the holding member 20. Specifically, a sliding mechanism (not shown) may be provided inside the holding member 20 for mounting the bearing so that it can move in the left-right direction.

[0023] A retaining member groove 63 is formed on the bottom surface of the retaining member 20. The retaining member groove 63 is a groove with a width of w2 and a depth of d1.

[0024] <<Support member 30>> The configuration of the support member 30 will be explained using Figures 1, 2, and 6. The support member 30 is installed on the base 10. The support member 30 is a plate capable of supporting the holding member 20 in an inclined position relative to the base 10. As shown in Figure 1, the support member 30 is pivotally supported on the base 10 at a support member pivot point 42 so that the base intersection angle at which the base 10 and the support member 30 intersect can be changed. The base crossing angle is the angle formed between the upper surface of the base 10 and the bottom surface of the support member 30. Furthermore, the support member 30 pivotally supports the holding member 20 at the holding member fulcrum 41 so that the angle at which the holding member intersects with the support member 30 can be changed. The retaining member intersection angle is the angle formed between the bottom surface of the retaining member 20 and the bottom surface of the support member 30. One end of the support member 30 is formed at an angle.

[0025] Figure 6 is a front view of the support member 30. As shown in Figures 2 and 6, the support member 30 has a width of w4, a depth of d3, and a height of h2. The width w4 of the support member 30 is half the width w3 of the retaining member 20. The depth d3 of the support member 30 is less than the depth d2 of the base storage section 80. The height h2 of the support member 30 is less than or equal to the height h1 of the base storage section 80.

[0026] The support member 30 includes a base fixing groove 64 and a retaining member fixing groove 65. The base fixing groove 64 is a groove formed on the surface of the support member 30 that faces the base 10. The width of the base fixing groove 64 is w2, and its depth is d3. The retaining member fixing groove 65 is a groove formed on the surface of the support member 30 that faces the retaining member 20. The width of the retaining member fixing groove 65 is w2, and its depth is d3.

[0027] The operation resulting from the structure of the trolley 101 will be explained using Figures 1, 7, and 8. Figure 7 shows the trolley 101 in a folded state. Figure 7 shows the case where the support member 30 does not support the retaining member 20. In this case, the base intersection angle is 0 degrees, the retaining member intersection angle is 180 degrees, and the retaining member 20 is superimposed on the base 10. Since the support member 30, which has a height h2, is housed in the base storage section 80, which has a height h1, the holding member 20 is stacked on top of the base 10 so as to be in surface contact with it.

[0028] Figure 8 shows how the holding member 20 of the trolley 101 is propped up. When propping up the holding member 20 of the trolley 101, the support member 30 is erected and the holding member 20 is supported by the support member 30. Then, the tilt of the holding member 20 is fixed by the fixing part 60. Fixing by the fixing part 60 means that one fixing member 61 is fitted into the base groove 62 and the base fixing groove 64 to fix the base so that the base intersection angle does not become smaller, and the other fixing member 61 is fitted into the retaining member groove 63 and the retaining member fixing groove 65 to fix the retaining member so that the retaining member intersection angle does not become smaller. In this way, the holding member 20 of the trolley 101 is supported at an angle to the base 10, as shown in Figure 1.

[0029] To change the position of the trolley 101's holding member 20 from an upright position to a horizontal position, the fixing part 60 must be released to fix the tilt of the holding member 20, and then the holding member 20 and the support member 30 should be folded so that the base crossing angle is 0 degrees and the holding member crossing angle is 180 degrees.

[0030] ***Method of using the trolley 101 of Embodiment 1*** The method of using the trolley 101 will be explained using Figures 9 and 10. Figure 9 is a flowchart showing an example of how to use the trolley 101. In the trolley 101, the holding member 20 is supported by a support member 30 installed on the base 10, thereby supporting the holding member 20 in an inclined position relative to the base 10 during use. Based on Figure 9, the method for using the trolley 101 from a folded state to an upright state will be explained.

[0031] <<Step S11>> In step S11, the support member 30 is erected at an arbitrary base intersection angle. The support member 30 is movable within a range of 0 to 90 degrees in terms of the base crossing angle. After step S11, the process proceeds to step S12.

[0032] <<Step S12>> In step S12, the base crossing angle is fixed by the fixing part 60. Specifically, the fixing member 61 is fitted into the base groove 62 provided in the base 10 and the base fixing groove 64 provided in the support member 30. After step S12, the process proceeds to step S13.

[0033] <<Step S13>> In step S13, the retaining member 20 is supported by the support member 30. Specifically, the holding member 20 is propped up at an arbitrary angle of intersection of the holding members. After step S13, proceed to step S14.

[0034] <<Step S14>> In step S14, the fixing part 60 fixes the intersection angle of the holding member. Specifically, the fixing member 61 is fitted into the retaining member groove 63 provided in the retaining member 20 and the retaining member fixing groove 65 provided in the support member 30. In step S14, the process of changing the trolley 101 from a folded state to an upright state is completed.

[0035] Figure 10 is a flowchart showing an example of how to use the trolley 101. In the trolley 101, the holding member 20 is not supported by the support member 30, so the holding member 20 is used by stacking it horizontally on the base 10. Based on Figure 10, the method for using the trolley 101 from an upright position to a folded position will be explained.

[0036] <<Step S21>> In step S21, the fixing member 61 that fixes the intersection angle of the retaining members is removed. This allows the angle of intersection of the retaining members to be changed. After step S21, the process proceeds to step S22.

[0037] <<Step S22>> In step S22, the fixing member 61 that fixes the base cross angle is removed. This allows the base crossing angle to be changed. After step S22, the process proceeds to step S23.

[0038] <<Step S23>> In step S23, the support member 30 is stored in the base storage section 80. When the support member 30 is tilted down to set the base intersection angle to 0 degrees, the support member 30 is stored in the base storage section 80. After step S23, the process proceeds to step S24.

[0039] <<Step S24>> In step S24, the retaining member 20 is placed on top of the base 10. Since the support member 30 is housed in the base storage section 80, when the angle of intersection of the holding members is set to 180 degrees (when the holding member 20 is parallel to the base 10), the holding member 20 is superimposed so as to make surface contact with the base 10. In step S24, the process of changing the trolley 101 from an upright position to a folded position is completed.

[0040] ***Example of use of the trolley 101 in Embodiment 1*** The trolley 101 is suitable for storing, transporting, and installing the flat cable 90 that transmits elevator control signals. This is because the flat cable 90 needs to be raised and lowered during transportation from the transport truck to the stockyard or near the elevator shaft, storage in the stockyard, and installation within the elevator shaft. The following describes examples of the use of the trolley 101 during the storage, transportation, and installation of the flat cable 90.

[0041] <<When storing>> The flat cable 90 is stored in a cardboard box 91 for packaging, while wound in a spiral shape. When the flat cable 90 is stored upright for a long period of time, pressure is applied to the flat cable 90 due to its own weight. This can cause the flat cable 90 to bend and develop a kink, potentially leading to malfunctions due to deterioration of its dynamic characteristics. Therefore, when storing the Flat Cable 90 in the stockyard, it is necessary to store it lying down so that its own weight does not put pressure on it.

[0042] Figure 11 shows an example of storing a flat cable 90 using a trolley 101. As shown in Figure 11, a cardboard box 91 containing the flat cable 90 is placed on the holding member 20 of the folded trolley 101. In this state, the combined center of gravity g of the holding member 20 and the flat cable 90 is located at the center of the contact surface between the rotation axis 50 and the holding member 20. At this time, it is desirable for the trolley 101 to be stable if the vertically downward direction of the center of gravity g is inside the wheel 70 installed on the base 10. Furthermore, when placing the cardboard box 91 on the holding member 20, a hole is made in the center of the cardboard box 91 in order to install the rotating shaft 50 in the space at the center of the spirally wound flat cable 90.

[0043] <<During transport>> Figure 12 shows an example of transporting a flat cable 90 using a trolley 101. As shown in Figure 12, the trolley 101 is used with the holding member 20 supported by the support member 30. When the holding member 20 is supported by the support member 30 and the flat cable 90 is placed on the holding member 20, the combined center of gravity g of the holding member 20 and the flat cable 90 is located at the center of the contact surface between the rotation axis 50 and the holding member 20. At this time, it is desirable for the trolley 101 to be stable if the vertically downward direction of the center of gravity g is at the center of the base 10. During transport, the worker pushes the holding member 20 to transport the trolley 101.

[0044] <<During installation>> The trolley 101 is placed on top of the elevator car, and the installation work of the flat cable 90 into the hoistway is carried out. Figure 13 shows an example of installing a flat cable 90 using a trolley 101. As shown in Figure 13, when installing the flat cable 90, the trolley 101 is used with the holding member 20 supported by the support member 30. The lid on top of the cardboard box 91 is opened, and the flat cable 90 is pulled out from there. After pulling out a portion of the flat cable 90, the end of the flat cable 90 is fixed inside the hoistway and the elevator car is lowered. In this way, the flat cable 90 is pulled out while rotating together with the rotating shaft 50.

[0045] ***Summary of Embodiment 1*** In this embodiment, the trolley 101 comprises a base 10, wheels 70 that support the base 10, a holding member 20 provided on the base 10 for holding an object, and a support member 30 provided on the base 10 that can be displaced between a position supported by the holding member 20 and a position not supported by the holding member 20. The retaining member 20 and the support member 30, and the support member 30 and the base 10 are connected by a hinge structure and are movable.

[0046] When the holding member 20 is in a supported position, the support member 30 supports the holding member 20 in an upright position. The state in which the holding member 20 is supported in an upright position allows the flat cable 90 to be placed upright, which is suitable for transporting and installing the flat cable 90. Furthermore, the trolley 101 has a structure that allows the angle of the holding member 20 and the support member 30 to be locked in an upright position. Therefore, the holding member 20 and the support member 30 will not fall over during the transportation or installation of the flat cable 90.

[0047] Furthermore, if the holding member 20 is not supported, the holding member 20 is placed horizontally on top of the base 10. By releasing the locks that secure each component, the retaining member 20 and the support member 30 can be tilted. When the retaining member 20 and the support member 30 are tilted, the support member 30 is structured to fit inside the base 10, and the retaining member 20 can be tilted horizontally. The position of the holding member 20 lying horizontally is suitable for storing the flat cable 90.

[0048] ***Effects of Embodiment 1*** As described above, in the first embodiment, the trolley 101 can hold an object upright by having the support member 30 support the holding member 20 with the support member 30 tilted relative to the base 10, and if the support member 30 does not support the holding member 20, the object can be held lying down by stacking the holding member 20 on the base 10, thereby reducing the burden required to switch between the upright and lying down positions of the object. In other words, the object can be switched between an upright and a horizontal position while remaining on the holding member 20. Therefore, when the flat cable 90 is placed on the holding member 20, it is no longer necessary to place the flat cable 90 on and off the trolley 101 each time the position of the flat cable 90 is switched between upright and horizontal. Thus, the transportation, storage, and installation of the flat cable 90 can be performed seamlessly, reducing the burden on workers.

[0049] Furthermore, the support member 30 is pivotally supported on the base 10 so that the base crossing angle can be changed, and the holding member 20 is pivotally supported on the support member 30 so that the holding member crossing angle can be changed, thus allowing the angle at which the holding member 20 is leaned to the side to be adjusted.

[0050] Furthermore, when the holding member 20 is held in an inclined position, the width of the trolley 101 will be greater than or equal to the width of the base 10 (w1) and less than the width of the holding member 20 (w3), thus making the width of the trolley 101 smaller than the width of the holding member 20. Furthermore, when the flat cable 90 is placed on the holding member 20 which is held in an inclined position, the width of the trolley 101 can be made smaller than the width of the flat cable 90. In other words, by holding the support member 20 in an inclined position, the width of the trolley 101 can be reduced, allowing the trolley 101 to be transported even in narrow spaces. The trolley 101 can also be placed on top of an elevator car. Therefore, by using the trolley 101 when installing the flat cable 90, the installation work can be performed on top of the elevator car instead of on the elevator landing, thus making the installation work more efficient.

[0051] Furthermore, since the holding member 20 is equipped with a rotating shaft 50, using the trolley 101 when installing the flat cable 90 can reduce the burden on the worker during installation. When installing the flat cable 90, it is necessary to pull the flat cable 90 out of the cardboard box 91. However, due to the weight of the flat cable 90, a certain amount of force is required to pull it out, which places a heavy burden on the worker. By setting the flat cable 90 on the rotating shaft 50, the force required to pull out the flat cable 90 is reduced, and even long flat cables 90 that are heavy can be easily handled.

[0052] ***Supplement to Embodiment 1*** In this embodiment, the object placed on the trolley 101 was assumed to be a flat cable 90, but it is not limited to this. The object may be a long, spiral-shaped strip, such as the flat cable 90. It may also be materials, luggage, or an animal.

[0053] In this embodiment, the flat cable 90 was placed on the holding member 20 while still packed in a cardboard box 91, but the flat cable 90 may also be placed on the holding member 20 after being removed from the cardboard box 91.

[0054] In this embodiment, a trolley 101 equipped with a holding device 100 and wheels 70 has been described, but it is also possible to use only the holding device 100.

[0055] In this embodiment, the holding member 20 and the receiving member 21 are pivotally supported by a hinge, but the embodiment is not limited to this. The receiving member 21 may be formed to be integrated with the holding member 20.

[0056] In this embodiment, the holding member 20 was equipped with a rotating shaft 50, but it is not limited to this. The holding member 20 does not necessarily have to include a rotating shaft 50. Furthermore, the holding member 20 may have a structure that allows the rotating shaft 50 to be housed inside the holding member 20.

[0057] In this embodiment, the support member 30 was plate-shaped, but it is not limited to this. The support member 30 may be in the shape of a rod. If the support member 30 is rod-shaped, the holding member 20 may be held by multiple support members 30.

[0058] In this embodiment, the support member pivot point 42 connected the bottom surface of the base storage section 80 and the left side surface of the support member 30, but is not limited to this. In particular, if the support member pivot point 42 is provided to connect the left side surface of the base 10 and the left side surface of the support member 30, the size of the base storage section 80 can be reduced. That is, the size of the base 10 can be reduced.

[0059] In this embodiment, the fixing portion 60 was composed of a fixing member 61, a base groove 62, a retaining member groove 63, a base fixing groove 64, and a retaining member fixing groove 65, but is not limited to this. The fixing portion 60 may include a hook fitting rotatably mounted on the front of the support member 30 and a hook fitting mounted on the front of the support member 30. By hooking the hook fitting onto the hook fitting, the angle at which the holding members intersect can be fixed.

[0060] In this embodiment, the base groove 62, the retaining member groove 63, the base fixing groove 64, and the retaining member fixing groove 65 are each formed in two locations, but the embodiment is not limited to this. The base groove 62, the retaining member groove 63, the base fixing groove 64, and the retaining member fixing groove 65 may be formed in one location or in multiple locations. If there are multiple base grooves 62, retaining member grooves 63, base fixing grooves 64, and retaining member fixing grooves 65, the base intersection angle and the retaining member intersection angle can be changed to any desired angle. Even when there is one base groove 62, one retaining member groove 63, one base fixing groove 64, and one retaining member fixing groove 65, the base intersection angle and the retaining member intersection angle can be changed to any angle by changing the size or shape of the fixing member 61.

[0061] In this embodiment, a base storage section 80 capable of housing the support member 30 was formed on the base 10, but the embodiment is not limited to this. The base 10 may be configured without a base storage section 80. In this case, the support member 30 is installed on the upper surface of the base 10. If the support member 30 does not support the retaining member 20, the support member 30 is placed on top of the base 10 so as to make surface contact with it, and the retaining member 20 is placed on top of the support member 30 so as to make surface contact with it.

[0062] Alternatively, the base 10 and the holding member 20 may be provided with a storage section 82 capable of housing the support member 30. Figures 14 and 15 show a trolley 101 equipped with a storage compartment 82. As shown in Figure 14, the trolley 101 has a base storage section 80 on the upper surface of the base 10, which is a recess in which a part of the support member 30 can be stored, and a retaining member storage section 81 on the bottom surface of the retaining member 20, which is a recess in which the other part of the support member 30 can be stored. As shown in Figure 15, the base storage section 80 and the retaining member storage section 81 form a storage section 82 which is a connected space. If the support member 30 does not support the retaining member 20, the support member 30 is stored in the storage section 82, and the retaining member 20 is placed on top of it so as to be in surface contact with the base 10.

[0063] Furthermore, the pivot point 41 of the retaining member and the pivot point 42 of the support member do not necessarily have to be the axis of the hinge. For example, as shown in Figure 15, the support point 41 of the retaining member may be configured such that a through hole is provided that penetrates the retaining member 20 and the support member 30, and an axis is passed through the through hole. The support member pivot point 42 may be configured such that a through hole is provided that penetrates the base 10 and the support member 30, and an axis is passed through the through hole.

[0064] Embodiment 2. ***Explanation of the structure*** The trolley 101 in Embodiment 2 will be described using Figures 16 and 17. Figure 16 is a front view of the trolley 101 according to Embodiment 2. As shown in Figure 16, the trolley 101 is equipped with wheels 70 and a holding device 100. This embodiment differs from Embodiment 1 in that the holding member 20 of the holding device 100 has a holding member intersection 22, and the support member 30 has a slide groove 31 and a hooking portion 23. Furthermore, this embodiment differs from Embodiment 1 in the configuration of the fixing part 60 and in the fact that it does not have a holding member pivot point 41 and a support member pivot point 42.

[0065] <<Holding member 20>> The holding member 20 comprises a rotating shaft 50, a receiving member 21, and a holding member intersection 22. The retaining member intersection 22 is an axis provided on the front and rear sides of the retaining member 20, respectively. The retaining member intersection 22 is fitted into the slide groove 31, which will be described later.

[0066] <<Support member 30>> The support member 30 includes a slide groove 31 and a hook portion 23. The support member 30 is attached vertically to the upper surface of the base 10. The slide groove 31 is a groove that allows the retaining member intersection 22 to slide up and down. The hook portion 23 secures the holding member intersection portion 22 to the support member 30 by hooking onto the holding member intersection portion 22. The hook portion 23 is a metal plate. An insertion opening is formed at the top of the support member 30 for inserting the hook portion 23, and the hook portion 23 is inserted into the insertion opening.

[0067] <<Base 10>> The base 10 is provided with a fixing part 60 for fixing the tilt of the holding member 20. The fixing portion 60 is a recess provided on the upper surface of the base 10. The fixing portion 60 is formed so that one end of the holding member 20 fits into it.

[0068] The following describes the state in which the holding member 20 of the trolley 101 is propped up. When the retaining member intersection 22 is positioned on the upper part of the support member 30, the support member 30 supports the retaining member 20. In other words, when the retaining member 20 is propped up, the retaining member intersection 22 is positioned on the upper part of the support member 30. The retaining member intersection 22 is hooked onto the hooking portion 23 and fixed to the upper part of the support member 30. Specifically, after the retaining member intersection 22 is positioned on the upper part of the support member 30, the hooking portion 23 is inserted into the insertion opening of the support member 30 to fix the position of the retaining member intersection 22. The tilt of the retaining member 20 is fixed by the fixing part 60. Specifically, when the retaining member 20 is propped up, one end of the retaining member 20 fits into the fixing part 60 like a stopper, fixing the retaining member 20 so that the angle of intersection of the retaining members does not become small.

[0069] When the holding member 20 of the trolley 101 is propped up and an object is placed on the holding member 20, the combined center of gravity g of the holding member 20 and the object is located at the center of the contact surface between the rotation axis 50 and the holding member 20. At this time, it is desirable for the trolley 101 to be stable if the vertically downward direction of the center of gravity g is at the center of the base 10.

[0070] The following explanation will use Figure 17 to describe the state in which the holding member 20 of the trolley 101 is laid down. Figure 17 is a front view of the trolley 101 according to Embodiment 2, with the holding member 20 laid flat. When the retaining member intersection 22 is positioned below the support member 30, the support member 30 does not support the retaining member 20. In other words, when the retaining member 20 is laid flat, the retaining member intersection 22 is positioned below the support member 30. In this case, the hook portion 23 is unnecessary. Furthermore, there is no need to fix the retaining member 20 with the fixing part 60.

[0071] When the holding member 20 of the trolley 101 is laid down and an object is placed on the holding member 20, the combined center of gravity g of the holding member 20 and the object is located at the center of the contact surface between the rotation axis 50 and the holding member 20. At this time, it is desirable for the trolley 101 to be stable if the vertically lower part of the center of gravity g is inside the wheels 70 installed on the base 10.

[0072] ***Effects of Embodiment 2*** As described above, in the second embodiment, the trolley 101 can hold an object upright by having the support member 30 support the holding member 20 with the support member 30 tilted relative to the base 10, and if the support member 30 does not support the holding member 20, the object can be held lying down by stacking the holding member 20 on the base 10, thereby reducing the burden required to switch between the upright and lying down positions of the object.

[0073] Furthermore, if the holding member 20 is held in an inclined position, the width of the trolley 101 can be reduced, allowing the trolley 101 to be transported even in narrow spaces.

[0074] Furthermore, when an object is placed on the holding member 20 of the trolley 101 while it is propped up, the vertically downward center of gravity g of the holding member 20 and the object is at the center of the base 10, so the object can be propped up in a stable position. Furthermore, when an object is placed on the holding member 20 of the trolley 101 while the holding member 20 is lying down, the vertically lower part of the combined center of gravity g of the holding member 20 and the object is located inside the wheels 70 installed on the base 10, allowing the object to be stored in a stable state.

[0075] ***Supplement to Embodiment 2*** In this embodiment, the fixing portion 60 is provided at one location on the upper part of the base 10, but it is not limited to this. The fixing parts 60 may be provided in any number of locations. By providing multiple fixing parts 60, it becomes possible to select the angle at which the holding member 20 is leaned.

[0076] In this embodiment, the hook portion 23 was used when positioning the holding member intersection portion 22 on the upper part of the support member 30, but the embodiment is not limited to this. It is not necessary to use the hook portion 23 to fix the position of the retaining member intersection portion 22. For example, by forming a hook groove extending in the left-right direction on the upper part of the slide groove 31 which is formed vertically, the retaining member intersection portion 22 can be hooked into the hook groove. Embodiment 3. ***Explanation of the structure*** The trolley 101 in Embodiment 3 will be described using Figures 18 and 19. Figure 18 is a front view of the trolley 101 according to Embodiment 3. As shown in Figure 18, the trolley 101 is equipped with wheels 70 and a holding device 100. This embodiment differs from Embodiment 2 in that the support member 30 of the holding device 100 does not have a slide groove 31. Furthermore, the structure of the hook portion 23 also differs from that of Embodiment 2.

[0077] <<Holding member 20>> The configuration of the retaining member 20 is the same as in Embodiment 2. However, the retaining member intersection 22 is hooked onto the hooking portion 23, which will be described later.

[0078] <<Support member 30>> The support member 30 is equipped with a hook portion 23. The support member 30 is attached vertically to the upper surface of the base 10. The hook portion 23 holds the holding member intersection portion 22 on the upper part of the support member 30. The hook portion 23 is a recess formed at the upper end of the support member 30. The retaining member intersection 22 is hooked onto the hook portion 23.

[0079] <<Base 10>> The configuration of the base 10 is the same as in Embodiment 2.

[0080] The following describes the state in which the holding member 20 of the trolley 101 is propped up. When the retaining member intersection 22 is hooked onto the hooking portion 23 of the support member 30, the support member 30 supports the retaining member 20. In other words, when the retaining member 20 is propped up, the retaining member intersection 22 is positioned at the upper end of the support member 30. The intersecting portion 22 of the holding member is hooked onto the hooking portion 23 and held on the upper part of the support member 30. Similar to Embodiment 2, the tilt of the holding member 20 is fixed by the fixing part 60.

[0081] When the holding member 20 of the trolley 101 is propped up and an object is placed on the holding member 20, the combined center of gravity g of the holding member 20 and the object is located at the center of the contact surface between the rotation axis 50 and the holding member 20. At this time, it is desirable for the trolley 101 to be stable if the vertically downward direction of the center of gravity g is at the center of the base 10.

[0082] The following explanation will use Figure 19 to describe the state in which the holding member 20 of the trolley 101 is laid down. Figure 19 is a front view of the trolley 101 according to Embodiment 3, with the holding member 20 laid flat. When the retaining member intersection 22 is positioned below the support member 30, the support member 30 does not support the retaining member 20. In other words, when the retaining member 20 is laid flat, the retaining member intersection 22 is positioned below the support member 30. In this case, the hook portion 23 is unnecessary. Furthermore, there is no need to fix the retaining member 20 with the fixing part 60.

[0083] When the holding member 20 of the trolley 101 is laid down and an object is placed on the holding member 20, the combined center of gravity g of the holding member 20 and the object is located at the center of the contact surface between the rotation axis 50 and the holding member 20. At this time, it is desirable for the trolley 101 to be stable if the vertically lower part of the center of gravity g is inside the wheels 70 installed on the base 10.

[0084] ***Effects of Embodiment 3*** As described above, in the second embodiment, the trolley 101 can hold an object upright by having the support member 30 support the holding member 20 with the support member 30 tilted relative to the base 10, and if the support member 30 does not support the holding member 20, the object can be held lying down by stacking the holding member 20 on the base 10, thereby reducing the burden required to switch between the upright and lying down positions of the object.

[0085] Furthermore, if the holding member 20 is held in an inclined position, the width of the trolley 101 can be reduced, allowing the trolley 101 to be transported even in narrow spaces.

[0086] Furthermore, when an object is placed on the holding member 20 of the trolley 101 while it is propped up, the vertically downward center of gravity g of the holding member 20 and the object is at the center of the base 10, so the object can be propped up in a stable position. Furthermore, when an object is placed on the holding member 20 of the trolley 101 while the holding member 20 is lying down, the vertically lower part of the combined center of gravity g of the holding member 20 and the object is located inside the wheels 70 installed on the base 10, allowing the object to be stored in a stable state.
