Description

[Technical Field]

[0001] The present invention relates to a cart device. [Background technology]

[0002] For example, Patent Document 1 discloses a cart device configuration that includes a rectangular support frame, four support posts attached to the front and rear of both sides of the support frame and equipped with casters at their lower ends, and at least two pairs of bag locking bars fixed to the upper ends of the four posts for locking the open ends of bags (garbage bags). With this configuration, the open ends of the bags are locked onto the bag locking bars, thereby holding the bags in an open state facing upward. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-193808 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the configuration disclosed in Patent Document 1, the bag locking bars extending in the front-to-rear direction are disposed on both sides of the cart in the width direction. Therefore, even when the bag is locked to the bag locking bars, the bag is not locked at the front or rear of the cart, and the entire opening of the bag is not stably held. Furthermore, the handles that workers hold when pushing the cart are disposed at the same height as the bag locking bars. Therefore, when a worker grips the handles, they may accidentally touch the bag locked by the bag locking bars, potentially causing discomfort to the user. An object of the present invention is to provide a cart device that can stably hold a bag body and improve the usability. [Means for solving the problem]

[0005] In order to achieve the above-mentioned object, a cart device according to one embodiment of the present invention is a cart device that is movable on a floor surface and comprises: a frame-shaped bag holding frame extending along the floor surface, in which the opening peripheral portion of the bag body is folded over to hold the bag body in the internal space; a first support pillar that is arranged at a distance outside the bag holding frame and extends in the vertical direction; a connecting member that has a downward extension portion that extends downward from the bag holding frame and is connected to the first support pillar; and a handle portion that is supported by the first support pillar and extends above the bag holding frame.

[0006] In this way, the bag body is stably held by holding the opening periphery of the bag body with a frame-shaped bag holding frame. By placing the bag body in the inner space of the bag holding frame and folding the opening periphery back to the outside of the bag holding frame, the opening periphery of the bag body is held by the bag holding frame. First support posts are arranged at intervals on the outside of the bag holding frame, and the bag holding frame and the first support posts are connected by a connecting member having a downward extension portion extending downward from the bag holding frame. This prevents the opening periphery of the bag body, which is folded back outward and engaged with the bag holding frame, from interfering with the connecting member. This makes it easy to engage the opening periphery of the bag body with the bag holding frame. Furthermore, because the handle extends above the bag holding frame, it is easy for the user to grasp the handle, and it is possible to prevent the user from accidentally touching the bag or the like held by the bag holding frame located below the handle, thereby improving the user experience.

[0007] In the cart device according to one aspect of the present invention, the bag holding frame may be continuous over the entire periphery in a plan view. According to this configuration, the bag holding frame is continuous over the entire periphery, so that the opening periphery of the bag body is held more stably.

[0008] In one aspect of the cart device of the present invention, the connecting members may be provided in multiple locations on the outside of the bag holding frame at intervals circumferentially of the bag holding frame, and may be removably hung around the multiple downward extension portions while spanning the multiple downward extension portions, and may include a bag body fixing member that clamps and fixes the opening peripheral portion of the bag body between the multiple downward extension portions. With this configuration, the opening periphery of the bag held by the bag holding frame can be fixed by the bag fixing member wound around the outer periphery of the downward extending portions of the multiple connecting members, thereby more reliably locking the bag to the bag holding frame.

[0009] The cart device according to one aspect of the present invention may further include a bag receiving member that is detachably provided below the bag holding frame and that is capable of receiving the bottom of the bag. With this configuration, the bag support member can support the bottom of the bag from below. This allows the bag support member to receive any contents that may leak from the bag. Furthermore, since the bottom of the bag is always supported from below by the bag support member, the load of the contents inside the bag can be prevented from concentrating on the portion of the bag's opening periphery that is held by the bag holding frame. Therefore, the bag can be stably held by the secondary holding frame.

[0010] In one embodiment of the cart device of the present invention, the bag holding frame may further include a second support pillar extending downward from a position different from the connecting member, and the second support pillar may have an outer extension portion positioned outward from the bag holding frame in a planar view. With this configuration, because the outward extensions of the second support posts are positioned outward relative to the bag holding frame, the gaps between adjacent second support posts and the gaps between the first and second support posts can be made wider than those of the bag receiving members. Therefore, even if the bag receiving member has the same outer shape in a plan view as the bag holding frame, it is not necessary to tilt the bag receiving member when passing it between adjacent support posts, and the bag receiving member can be easily inserted and removed.

[0011] In one embodiment of the cart device of the present invention, the first support pillars may be provided on the outside of the bag holding frame at intervals in the circumferential direction of the bag holding frame, and adjacent first support pillars may be arranged at an interval that allows the bag body receiving member to be inserted therethrough. According to this configuration, the plurality of first support posts are provided at intervals that allow the bag body receiving member to be inserted therethrough, so that the bag body receiving member can be easily inserted and removed.

[0012] In the cart device according to one aspect of the present invention, the handle may be provided with an article locking portion capable of locking an article. According to this configuration, an article can be locked to the article locking portion, which increases the convenience of the cart device.

[0013] In the cart device according to one aspect of the present invention, the article locking portion may be arranged vertically above the inner space. With this configuration, the article suspended from the article fastening portion can be easily stored inside the bag body housed in the inner space of the bag holding frame.

[0014] In the cart device according to one aspect of the present invention, at least a portion of the handle may protrude rearward relative to the direction of travel of the cart device. With this configuration, the user can easily grip the portion of the handle that protrudes rearward.

[0015] In the cart device of the present invention, the first support pillar and the handle portion may be provided on both sides of the width of the cart device, and may further include a bar extending in the width direction and connecting the handle portions on both sides of the width direction.

[0016] With this configuration, the user can move the cart device forward and backward stably by grasping the bar connecting the handles on both sides in the width direction. In addition, by connecting the handles on both sides in the width direction with the bar, the handles can be reinforced. [Effects of the Invention]

[0017] According to one aspect of the present invention, the bag body can be stably held and the usability can be improved. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cart device according to an embodiment of the present invention will now be described with reference to the accompanying drawings. However, the present invention is not limited to this embodiment.

[0020] Fig. 1 is a perspective view showing the overall configuration of a cart device 1A according to an embodiment of the present invention. Fig. 2 is a perspective view of the cart device 1A seen from a direction different from that shown in Fig. 1. Fig. 3 is a side view of the cart device 1A. 1 to 3, the cart apparatus 1A is configured to be movable on a floor surface F. In the following description, a direction perpendicular to the floor surface F is referred to as a vertical direction Dv, a direction perpendicular to the vertical direction Dv and moving direction of the cart apparatus 1A on the floor surface F is referred to as a front-rear direction Da, and a direction perpendicular to the vertical direction Dv and the front-rear direction Da is referred to as a width direction Dw of the cart apparatus 1A. The cart device 1A mainly comprises a support 2, a frame-shaped bag holding frame 3, a bag receiving member 4, a connecting member 5, a handle portion 6, and an article locking portion .

[0021] In a plan view, a plurality of support pillars 2 are provided around the bag holding frame 3. Each support pillar 2 is made of, for example, a metal pipe with a circular cross section and extends in the vertical direction Dv. A caster 2c is provided at the bottom end of each of the plurality of support pillars 2, allowing the cart device 1A to move on the floor surface F. In this embodiment, the plurality of support pillars 2 include a rear support pillar (first support pillar) 21 located at the rear of the cart device 1A in the front-to-rear direction Da, and a front support pillar (second support pillar) 22 located at the front of the cart device 1A.

[0022] The bag holding frame 3 is supported by the upper ends of multiple support columns 2. The bag holding frame 3 is formed along a plane (horizontal plane) parallel to the floor surface F. When viewed from above, the bag holding frame 3 is formed into a rectangular frame shape. The inside of the bag holding frame 3 defines an inner space 3s that penetrates in the up-down direction Dv. The bag holding frame 3 is made of, for example, a metal pipe with a circular cross section. The bag holding frame 3 has a pair of first members 31 provided on both sides in the width direction Dw and a pair of second members 32 provided on both sides in the front-rear direction Da. Each first member 31 extends in the front-rear direction Da. Each second member 32 extends in the width direction Dw. The second member 32 located at the front connects the front ends of the pair of first members. The second member 32 located at the rear connects the rear ends of the pair of second members. Thus, in this embodiment, the bag holding frame 3 is continuous around the entire circumference when viewed from above. As long as the bag holding frame 3 has a frame-like outer shape in plan view, it may not be continuous around the entire circumference but may be provided intermittently in the circumferential direction. Also, the bag holding frame 3 may have an annular shape when viewed from above.

[0023] FIG. 4 is a diagram showing the configuration of the joint between the frame holding frame and the support pillars. FIG. 5 is a cross-sectional view showing the configuration of the joint between the frame holding frame and the support pillars. The rear end of the bag holding frame 3 is connected to rear support pillars 21 on both sides in the width direction Dw via connecting members 5. The rear support pillars 21 extend linearly in the up-down direction Dv. The upper end of the rear support pillars 21 is positioned below the bag holding frame 3. The rear support pillars 21 are arranged outside the bag holding frame 3 (rearward and outside in the width direction Dw) and spaced apart from the bag holding frame 3. Therefore, the distance between adjacent rear support pillars 21 in the circumferential direction of the bag holding frame 3 is wider than the dimension of the bag holding frame 3 in the width direction Dw.

[0024] The connecting member 5 connects the bag holding frame 3 and the rear support column 21. One end of the connecting member 5 is connected to, for example, a corner 3c of the bag holding frame 3 where the rear end of the first member 31 and the end of the second member 32 are connected. As shown in Figures 4 and 5, the connecting member 5 is L-shaped. Specifically, the connecting member 5 integrally includes a downward extension 51 extending downward from the corner 3c of the bag holding frame 3 and a lateral extension 52 extending laterally from the lower end of the downward extension 51. The lateral extension 52 is connected to the upper end of the rear support column 21. Therefore, a gap equal to or smaller than the length of the lateral extension 52 is formed between the bag holding frame 3 and the rear support column 21 in a plan view. The connecting member 5 is made of, for example, a metal rod having an outer diameter smaller than that of the metal pipe that forms the bag holding frame 3.

[0025] As shown in Figures 1 to 4, the front end of the bag holding frame 3 is directly connected to front support columns 22 on both sides in the width direction Dw. The upper ends of the front support columns 22 are connected to, for example, corners 3d of the bag holding frame 3 where the front end of the first member 31 and the end of the second member 32 are connected in the bag holding frame 3. The front support columns 22 extend downward from positions on the bag holding frame 3 that are different from the positions of the connecting members 5. In this embodiment, the front support columns 22 are integrally provided with an upper extension portion 22a, an inclined extension portion 22b, and an outward extension portion 22c. The upper extension portion 22a extends vertically downward from the corners 3d of the bag holding frame 3. The inclined extension portion 22b extends downward from the lower end of the upper extension portion 22a, inclined outward relative to the bag holding frame 3. In this embodiment, the inclined extension portion 22b extends downward from the lower end of the upper extension portion 22a, slanting outward in the width direction Dw and forward with respect to the corner 3d of the bag holding frame 3. The outer extension portion 22c extends vertically downward from the lower end of the inclined extension portion 22b. In a plan view, the outer extension portion 22c is located outward (outward in the width direction Dw and forward) with respect to the corner 3d of the bag holding frame 3. Note that the front support 22 may also extend linearly in the up-down direction Dv.

[0026] Such a bag holding frame 3 holds the opening periphery 100f of the bag body 100. The bag body 100 is made of, for example, vinyl resin, and is tubular in shape extending in the vertical direction, with its lower end closed and its opening facing upward. The bag body 100 is inserted into the inner space 3s of the bag holding frame 3. The opening periphery 100f of the bag body 100 is folded back to the outside of the bag holding frame 3 so as to cover the bag holding frame 3 from above. This allows the bag body 100 to be held by the bag holding frame 3. The bag body 100 catches the lower end of the article held by the article holding portion 7, as well as liquid dripping from the article.

[0027] 4 and 5, a bag holding pad 38 may be attached to the bag holding frame 3. The bag holding pad 38 covers the bag holding frame 3 from above and has a larger radius of curvature than the outer peripheral surface of the bag holding frame 3. This allows the bag holding frame 3 to come into contact with the bag holding pad 38, which has a larger radius of curvature, when the opening peripheral edge 100f of the bag body 100 is folded outward. This allows the opening peripheral edge 100f to come into contact with the outer peripheral surface of the bag holding pad 38 over a larger area. Note that it is preferable to use a material, such as a resin material, that has a high coefficient of friction with respect to the bag holding frame 3 and a low modulus of elasticity for the bag holding pad 38.

[0028] The opening periphery 100f of the bag body 100 is fixed below the bag holding frame 3 by a bag body fixing member 120. The bag body fixing member 120 is wound around the downward extensions 51 of each connecting member 5 and the outer periphery of the upper extensions 22a of each front support column 22 while spanning the downward extensions 51 of each connecting member 5 and the outer periphery of the upper extensions 22a of each front support column 22. The bag body fixing member 120 is, for example, in the form of a belt made of a soft and flexible material and is configured to be detachable with a buckle or the like. The opening periphery 100f of the bag body 100 can be fixed by fastening the bag body fixing member 120 and sandwiching the opening periphery 100f between the bag body fixing member 120 and the downward extensions 51 of each connecting member 5 and the upper extensions 22a of each front support column 22.

[0029] The bag body fixing member 120 may be endless by being made stretchable using a rubber-based material or the like. In this case, the bag body fixing member 120 may be attached to and detached from the underside of the bag holding frame 3 by passing it through the bag holding frame 3 in a stretched state and then restoring it to its original shape. Alternatively, the bag body fixing member 120 may be made of a resin-based material, a metal-based material, or the like, and configured as multiple segments divided in the circumferential direction of the bag holding frame 3, and the multiple segments may be connected and combined together so as to be wound around the downward extension 51 and the outer periphery of the upper extensions 22a of each front support 22.

[0030] The bag body receiving members 4 are provided below the bag holding frame 3. The bag body receiving members 4 are connected to each other below the bag holding frame 3 by connecting members 25 provided between the multiple support columns 2. The bag body receiving members 4 are placed on the connecting members 25. A receiving member holding frame 29 is provided above the connecting members 25. The receiving member holding frame 29 has a rectangular ring shape in a plan view, and is joined to the multiple support columns 2 on the outer periphery.

[0031] The bag body receiving member 4 is housed inside the receiving member holding frame 29. The bag body receiving member 4 is in the shape of a bottomed container with an opening facing upward. The bag body receiving member 4 has, for example, a rectangular bottom plate 41 when viewed from above, and side plates 42 rising upward from the four sides of the bottom plate 41.

[0032] Such a bag receiving member 4 is disposed below the bag 100 whose opening peripheral edge 100f is held by the bag holding frame 3. The bag receiving member 4 may be configured to always be in contact with the bag 100 from below, or may be spaced below the lower end of the bag 100. The bag receiving member 4 has the function of supporting the weight of the storage section contained within the bag 100, and of receiving the contents that leak out in the unlikely event that the contents leak out of the bag 100.

[0033] The front-to-rear dimension S1 of the bag body receiving member 4 is smaller than the distance S3 between the rear support column 21 and the outward extending portions 22c of the front support columns 22. The width dimension S2 of the bag body receiving member 4 is smaller than the distance S4 between the outward extending portions 22c of the front support columns 22 on both sides in the width direction Dw. This allows the bag body receiving member 4 to be easily inserted and removed from the connecting member 25 through the gap between the rear support column 21 and the outward extending portions 22c of the front support columns 22, or the gap between the outward extending portions 22c of the front support columns 22 on both sides in the width direction Dw.

[0034] As shown in Figures 2 and 3, the handle 6 is formed integrally with the rear support pillar 21. In other words, the handle 6 is supported by the rear support pillar 21. The handle 6 extends above the bag holding frame 3. The handle 6 integrally includes a rearward curved portion 61 that extends upward from the upper end of the rear support pillar 21, curving or tilting backward, and a protruding portion 62 that extends rearward from the upper end of the rearward curved portion 61. The protruding portion 62 is U-shaped when viewed from the side, and integrally includes a lower protruding portion 62a that extends upward from the upper end of the rearward curved portion 61, curving backward, and an upper protruding portion 62b that extends upward from the lower protruding portion 62a, curving forward.

[0035] The handles 6 are provided on the rear support columns 21 on both sides in the width direction Dw. That is, the handles 6 are provided on both sides in the width direction Dw of the cart device 1A. The handle portions 6 on both sides in the width direction Dw are connected to each other by a bar 65 extending in the width direction Dw. In this embodiment, both ends of the bar 65 are connected to the protrusions 62 (upper protrusions 62b) of the handle portions 6. A user can move the cart device 1A in the front-to-rear direction by gripping the protruding portions 62 of the handle portions 6 on both sides in the width direction Dw with both hands. Alternatively, a user can grip the center portion of the bar 65 with one hand and move the cart device 1A in the front-to-rear direction.

[0036] As shown in FIG. 1 , the article locking portion 7 is provided on the handle portion 6. The article locking portion 7 includes support rods 71 ​​extending forward continuously from the front ends of the upper protrusions 62b on both sides in the width direction Dw, and a locking portion main body 72 provided between the support rods 71 ​​on both sides in the width direction Dw. The locking portion main body 72 is formed in a plate shape along a plane intersecting with the up-down direction Dv. The locking portion main body 72 is spaced vertically above the inner space 3s of the bag holding frame 3 and is disposed in a state overlapping the inner space 3s in a plan view. A holding recess 73 is formed at the front end of the locking portion main body 72, recessed toward the rear and capable of locking an article. A plurality of holding recesses 73 are formed at intervals in the width direction Dw. An article such as an endoscope can be locked in the holding recess 73.

[0037] In this embodiment, a storage tray 9 is provided behind the rear support columns 21. The storage tray 9 has a bottomed container shape that opens upward, and is attached to the rear sides of the rear support columns 21 on both sides in the width direction Dw.

[0038] As described above, in this embodiment, the opening peripheral portion 100f of the bag body 100 is held by the frame-shaped bag holding frame 3. This allows the bag body 100 to be stably held. Furthermore, by placing the bag body 100 in the inner space 3s of the bag holding frame 3 and folding the opening peripheral portion 100f outward from the bag holding frame 3, the opening peripheral portion 100f of the bag body 100 is held by the bag holding frame 3. Furthermore, the rear support pillars 21 are disposed outside the bag holding frame 3 at a distance from each other, and the bag holding frame 3 and the rear support pillars 21 are connected by connecting members 5 having downward extensions 51 extending downward from the bag holding frame 3. Therefore, the opening peripheral portion 100f of the bag body 100, which is folded outward and engaged with the bag holding frame 3, is prevented from interfering with the support pillars 2. This allows the opening peripheral portion 100f of the bag body 100 to be easily engaged with the bag holding frame 3. Furthermore, in this embodiment, the handle 6 is configured to extend above the bag holding frame 3. This makes it easier for the user to grasp the handle 6 and prevents the user from accidentally touching the bag 100 or the like held by the bag holding frame 3, which is located below the handle 6. This improves the user experience. Therefore, the bag body 100 can be stably held and the feeling of use can be improved.

[0039] In this embodiment, the bag holding frame 3 is configured to be continuous over the entire periphery in plan view. According to this configuration, the bag holding frame 3 is continuous over the entire periphery, so that the opening peripheral edge 100f of the bag body 100 is held more stably.

[0040] In this embodiment, a configuration is provided in which a bag body fixing member 120 is detachably hung across the outer periphery of the plurality of downward extending portions 51 in a state of straddling the outer periphery. With this configuration, the opening peripheral portion 100f of the bag body 100 held by the bag holding frame 3 can be fixed by the bag body fixing member 120 wound around the outer periphery of the downward extending portions 51 of the multiple connecting members 5. Therefore, the bag body 100 is more reliably locked to the bag holding frame 3.

[0041] In this embodiment, a bag receiving member 4 is provided below the bag holding frame 3. With this configuration, the bag receiving member 4 can support the bottom of the bag 100 from below. As a result, in the unlikely event that the contents leak out of the bag 100, the leaked contents can be received by the bag receiving member 4. Furthermore, when the bottom of the bag 100 is always supported from below by the bag receiving member 4, the load caused by the contents inside the bag 100 can be prevented from concentrating on the portion of the opening periphery 100f of the bag 100 held by the bag holding frame 3. Therefore, the bag 100 can be stably held by the bag holding frame 3.

[0042] In this embodiment, the front support pillar 22 is configured to have an outer extension 22c that is positioned outward relative to the bag holding frame 3 in a plan view. With this configuration, outer extensions 22c of front support columns 22 are positioned outward relative to bag holding frame 3, so that the gaps between adjacent front support columns 22 and the gaps between rear support columns 21 and front support columns 22 can be made wider than with bag body receiving member 4. Therefore, even if bag body receiving member 4 has an outer shape in a plan view similar to that of bag holding frame 3, it is not necessary to tilt bag body receiving member 4 when passing between adjacent support columns 2, and bag body receiving member 4 can be easily inserted and removed.

[0043] In this embodiment, the handle 6 is provided with an article locking portion 7. According to this configuration, articles can be locked to the article locking portion 7, and the convenience of the cart device 1A is improved.

[0044] In this embodiment, the article locking portion 7 is configured to be disposed vertically above the inner space 3s. With this configuration, the article suspended from the article fastening portion 7 can be easily stored inside the bag body 100 housed in the inner space 3s of the bag holding frame 3.

[0045] In this embodiment, the protruding portion 62 of the handle portion 6 is configured to protrude rearward from the cart apparatus 1A. With this configuration, the user can easily grip the portion of the handle 6 that protrudes rearward.

[0046] The cart device 1A according to the present invention is further provided with a bar 65 that connects the handle portions 6 on both sides in the width direction Dw. With this configuration, the user can stably move the cart device 1A forward and backward by grasping the bar 65. Furthermore, by connecting the handle portions 6 on both sides in the width direction Dw with the bar 65, the handle portions 6 can be reinforced.

[0047] (Modification of the embodiment) Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the appended claims. For example, in the above-described embodiment, the upper end of the front support column 22 is directly connected to the bag holding frame 3, but this is not limitative. FIG. 6 is a perspective view showing the overall configuration of a cart apparatus 1B according to a modified example of the embodiment of the present invention. As shown in FIG. 6, the cart device 1B mainly includes a plurality of support posts 2, a frame-shaped bag holding frame 3, a bag receiving member 4, a connecting member 5, a handle portion 6, and an article fastening portion 7. In this modified example, the multiple support columns 2 include a rear support column 21 arranged at the rear of the cart apparatus 1B in the front-rear direction Da, and a front support column (first support column) 24 arranged at the front of the cart apparatus 1B.

[0048] The front end of the bag holding frame 3 is connected to front support columns 24 on both sides in the width direction Dw via connecting members 5. The front support columns 24 are arranged outside the bag holding frame 3 with a gap between them. The connecting members 5 connect the bag holding frame 3 to the front support columns 24. One end of the connecting member 5 is connected to a corner 3d of the bag holding frame 3. The connecting member 5 integrally has a downward extension 51 extending downward from the corner 3d of the bag holding frame 3, and a lateral extension 52 extending laterally from the lower end of the downward extension 51. The lateral extension 52 is connected to the upper end of the front support columns 24.

[0049] The opening periphery 100f of the bag body 100 inserted into the inner space 3s of the bag holding frame 3 is folded back to the outside of the bag holding frame 3 so as to cover the bag holding frame 3 from above. The opening periphery 100f is fixed on the underside of the bag holding frame 3 by a bag body fixing member 120. The bag body fixing member 120 is wound around the outer periphery of the downward extensions 51 of the multiple connecting members 5 connected to the rear support column 21 and the front support column 24. The opening periphery 100f of the bag body 100 can be fixed by tightening the bag body fixing member 120 and sandwiching the opening periphery 100f between the bag body fixing member 120 and the downward extensions 51 of each connecting member 5.

[0050] In the rear support pillars 21 and front support pillars 24 provided in multiple numbers on the outside of the bag holding frame 3, the spacing S11 between adjacent support pillars 2 is set larger than the dimension S1 of the bag body receiving member 4 so that the bag body receiving member 4 can be inserted.

[0051] In this embodiment, the rear support 21 as the first support and the front support 24 are provided at a distance that allows the bag body receiving member 4 to be inserted therethrough, so that the bag body receiving member 4 can be easily inserted and removed.

[0052] (Another modified example of the embodiment) In the above embodiment, a part of the handle 8 (the protruding portion 82) protrudes rearward, but the present invention is not limited to this. FIG. 7 is a perspective view showing the overall configuration of a cart apparatus 1C according to another modified example of the embodiment of the present invention. 7, rear support column 21 and front support column 24 may be integrally provided with extensions 21C, 24C that extend so as to protrude upward beyond bag holding frame 3, and connecting rods 88 may be provided on both sides of width direction Dw, extending in front-to-rear direction Da to connect the upper ends of extensions 21C and 24C. A user grips rear extension 21C or connecting rod 88 as a handle 8C to move cart device 1C. In this case, the article locking portion 7 may be supported by the connecting rods 88 on both sides in the width direction Dw.

[0053] (Other variations) In the above-described embodiment and variant examples, the bag holding frame 3 is supported by four pillars 2, but the number of pillars 2 supporting the bag holding frame 3 may be one, two, three, or five or more.

[0054] In the above-described embodiment, an endoscope has been given as an example of an article to be locked to the article locking portion 7, but this is not limiting. Other articles can be appropriately locked to the article locking portion 7. For example, the tip of a cleaning tool such as a mop may be housed in the bag body 100, and the handle may be locked to the article locking portion 7.

[0055] In the above-described embodiment, the lower part of the article to be locked by the article locking portion 7 is accommodated within the bag body 100, but this is not limited to this. There are no limitations on the articles to be accommodated in the bag body 100. For example, waste or the like may be accommodated within the bag body 100. In this case, the article locking portion 7 may not be positioned vertically above the inner space 3s of the bag holding frame 3, but may be positioned, for example, behind the bag holding frame 3.

[0056] In the above-described embodiment, the connecting member 5 is configured to include the downward extending portion 51 and the side extending portion 52, but the present invention is not limited to this configuration. The connecting member 5 may be configured in any way so long as it connects the bag holding frame 3 and the rear support column 21 with a gap between them, and may be configured, for example, so that the downward extending portion 51 extends at an angle to the side as it extends downward. In the above-described embodiment, a configuration in which the bag body 100 is fixed by the bag body fixing member 120 has been described, but the bag body fixing member 120 is not an essential configuration. In that case, the end of the bag body 100 may be fixed by folding back the end and sandwiching it between the downward extension portion 51 and a support (for example, the rear support 21 or the front support 24). In the above-described embodiment, the handle portion 6 is integrally formed with the rear support pillar 21, etc., but the present invention is not limited to this configuration. The handle portion 6 may be formed separately from the rear support pillar 21. In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described modified examples may be combined as appropriate.
