[0001] The present invention relates to a foldable chute for unloading.

Background Art

[0002] Patent Document 1 discloses a chute for carrying out articles from an upper floor of a building to the ground outside the building. The chute has an article sliding portion for sliding articles, which is constituted by a flexible cloth belt (flexible sheet), and is used, for example, in operations such as relic sorting and waste collection. The upper end portion and the lower end portion of the flexible cloth belt are fixed to surrounding fixtures by ropes.

[0003] According to the chute of Patent Document 1, since the article sliding portion itself is made of a flexible cloth belt, articles slide while being flexibly supported, and are conveyed downward while decelerating by receiving appropriate frictional resistance from the cloth belt. In addition, the chute of Patent Document 1 can be easily folded and has high mobility.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Among the articles unloaded from an upper floor of a building as in Patent Document 1 above, there are relatively light articles such as personal belongings, and there are also heavy articles such as furniture. Although it is possible to sufficiently decelerate light articles by the frictional resistance of the flexible sheet, in the case of relatively heavy articles, they may not be sufficiently decelerated by the time they reach the lower end of the article sliding portion. In addition, it is required that articles can be smoothly carried out at the lower end of the article sliding portion.

[0006] The present invention has been made in view of the above, and its object is to provide a loading chute that can appropriately stop articles at the lower end of the chute body and appropriately enable smooth article unloading operations. [Means for solving the problem]

[0007] The unloading chute according to the present invention is installed at an incline from the upper floor of a building to the ground outside the building, and comprises a chute body made of a flexible, strip-shaped sheet material, and fixing ropes for fixing the upper and lower ends of the chute body to surrounding fixed objects, respectively, and is a foldable unloading chute configured to transport articles received from the upper floor by sliding them down the chute body, wherein the chute body has an article sliding section on which the articles slide, and rope holding sections provided on both the left and right sides of the article sliding section, extending in the longitudinal direction of the chute body and holding the fixing ropes while covering them, and is equipped with a stopper that is detachably attached and fixed to the lower end of the chute body and includes an impact absorbing material.

[0008] With the above configuration, even if the weight of the unloaded goods is relatively large and it is not possible to sufficiently reduce the speed of the goods before they reach the lower end of the goods sliding section, a stopper containing shock-absorbing material is attached and fixed to the lower end of the chute body, making it possible to properly stop the goods with the stopper.

[0009] In this case, if the items to be unloaded are relatively light, as described above, the item sliding section with a flexible sheet material can sufficiently reduce the speed of the items. Therefore, in this case, a stopper is unnecessary, and there is a problem in that the stopper becomes a physical obstacle to the unloading operation when the items are unloaded from the chute. Furthermore, even if the weight of the items is relatively large, once the items are stopped by the stopper, the stopper can become a physical obstacle to the unloading operation.

[0010] In contrast, the stopper in this invention has a configuration that allows it to be attached to and detached from the chute body. Therefore, when unloading relatively lightweight items, or when removing items that have been stopped by the stopper from the chute body, the stopper can be removed from the chute body to facilitate the removal of items. In other words, it is possible to appropriately stop the items at the lower end of the chute body according to their weight and to smoothly remove the items.

[0011] Furthermore, since the chute itself is made of a flexible, strip-shaped sheet material, the chute can be easily and compactly folded by removing the stopper.

[0012] Furthermore, it is preferable that the stopper has a convex portion, and that the lower end of the chute body is attached and fixed along the convex portion of the stopper, so that the article sliding portion forms a U-shaped recessed track.

[0013] In this case, if the sliding object is a heavy object with corners, such as a rectangular parallelepiped, the chute body may suffer significant wear due to concentrated frictional resistance from the corners of the object.

[0014] In contrast, with the above configuration, the lower end of the chute body is fixed and maintained in a shape that follows the convex portion of the stopper, thereby forming a U-shaped recessed path in the chute body. As a result, the frictional resistance that the chute body receives from the article can be effectively reduced. In addition, the U-shaped recessed path allows the article to be guided downward stably. In other words, this configuration suppresses wear on the chute body and allows the article to slide downward stably.

[0015] Furthermore, it is preferable that the lower end of the chute body has a first engaging portion on the surface on which the article slides, and that the stopper has a second engaging portion that detachably engages with the first engaging portion. By providing such first and second engaging portions, a configuration in which the stopper can be detachably attached to the lower end of the chute body can be suitably realized.

[0016] Furthermore, it is desirable that the chute body has a third engaging portion provided on the back surface of the lower end of the chute body, opposite to the side on which the article slides, and a fourth engaging portion arranged side by side with respect to the third engaging portion on the upper end of the chute body, and that the first engaging portion is positioned on the back surface of the chute body by the third engaging portion detachably engaging with the fourth engaging portion when the lower end of the chute body is folded back to the back side.

[0017] Here, when the stopper is removed from the lower end of the chute body, the surface of the chute body has a first engaging portion, which may cause the item to unintentionally get caught on the first engaging portion or to be damaged by contact with the first engaging portion.

[0018] In contrast, with the above configuration, the first engaging portion can be positioned and fixed on the back side of the chute body by folding the lower end of the chute body where the first engaging portion is located to the back side and engaging the third engaging portion with the fourth engaging portion.

[0019] As a result, when a stopper is not required, the first engagement portion is not provided on the surface side of the chute body, allowing for smooth transport of goods and preventing damage to the goods.

[0020] On the other hand, when a stopper is needed, the third engaging part is detached from the fourth engaging part, and the lower end of the chute body, which had been folded back, is returned to the surface side, thereby allowing the stopper to be attached to the lower end.

[0021] Furthermore, the rope holding part is a part adjacent to the lower end part of the chute main body, and is folded back to the inside of the chute main body. Furthermore, covering the aforementioned fixing rope It preferably has a deployable part that can be deployed to the outer side in the lateral direction from the folded state, and the deployed deployable part is configured to be foldable back to the back side together with the lower end part of the chute main body.

[0022] According to the above configuration, for example, when attaching a stopper to the lower end part of the chute main body, the deployable part of the rope holding part can be in the folded state, and the fixing rope can be held by the deployable part. On the other hand, when folding the lower end part of the chute main body back to the back side, by folding the deployable part back to the back side together with the lower end part, the fixing rope can be held by the lower end part of the rope holding part adjacent to the deployable part.

[0023] Therefore, in both the use state where the stopper is attached to the lower end part of the chute main body and the use state where the stopper is removed and the lower end part of the chute main body is folded back to the back side, the fixing rope can be appropriately held on the lower end side of the chute main body.

[0024] Furthermore, the deployable part is formed in a sheet shape and has a fifth engaging part provided on the back surface of the deployable part, and the fifth engaging part is preferably configured to be detachably engaged with a part of the first engaging part when the deployable part is in the folded state. Thereby, it becomes possible to fix the deployable part in a folded state to the lower end part of the chute main body by using the first engaging part used for attaching and fixing the stopper.

[0025] Furthermore, the deployable part has a sixth engaging part provided on the front surface of the deployable part, and the sixth engaging part is preferably configured to be detachably engaged with the second engaging part in the stopper together with the first engaging part when the deployable part is in the folded state. be It preferably has a deployable part that can be deployed to the outer side in the lateral direction from the folded state, and the deployed deployable part is configured to be foldable back to the back side together with the lower end part of the chute main body.

[0026] As a result, by engaging the second engaging portion of the stopper with the sixth engaging portion of the deployable section that holds the fixing rope, the stopper can be attached and fixed not only to the lower end of the chute body but also to the fixing rope. Therefore, the stopper can be fixed more firmly, making it possible to reliably stop sliding objects. [Effects of the Invention]

[0027] According to the present invention, it is possible to provide a loading chute that appropriately stops articles at the lower end of the chute body and allows for smooth article unloading. [Brief explanation of the drawing]

[0029] Embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the embodiments described below.

[0030] Figure 1 is a side view showing the exterior of the unloading chute 1 installed in building 5 in this embodiment. Figure 2 is a perspective view showing the lower part of the unloading chute 1. Figure 3 is a side view showing the support member 15 that supports the upper part of the unloading chute 1. Figure 4 is a perspective view showing the stopper 20 in this embodiment.

[0031] The unloading chute 1 is used to unload items A, such as books, clothing, home appliances, and furniture, from the upper floors of building 5, for purposes such as sorting through belongings or removing unwanted items from rooms.

[0032] As shown in Figures 1 and 2, the unloading chute 1 comprises a chute body 10 installed at an angle from the upper floors of a building 5 (two stories or more) toward the ground G outside the building 5, and fixing ropes 13 for securing the upper and lower ends of the chute body 10 to surrounding fixed objects, respectively. The unloading chute 1 is configured to unload goods A received from the upper floors of the building 5 by sliding them downwards in the chute body 10.

[0033] The chute body 10 is made of a flexible, strip-shaped sheet material. Preferably, the chute body 10 is made of, for example, tire cord. Tire cord is a reinforcing material generally used to maintain the shape of a tire. Tire cord is made of at least one type of fiber from the group consisting of, for example, polyester, nylon, aramid, and rayon. In addition to tire cord, other flexible sheet materials such as canvas can also be used for the chute body 10.

[0034] The unloading chute 1 is designed to be foldable because the chute body 10 is made of a flexible sheet material. As shown in Figure 2, the chute body 10 has an article sliding section 11 on which article A slides, and rope holding sections 12 provided on both the left and right sides of the article sliding section 11.

[0035] The article sliding section 11 and the rope holding section 12 extend in the longitudinal direction of the chute body 10, and the article A is configured to slide along the article sliding section 11 in that longitudinal direction.

[0036] Here, Figures 5 and 6 show the lower parts of the chute body 10, respectively. Figure 5 is a front view showing the front side of the chute body 10, while Figure 6 is a rear view showing the back side of the chute body 10.

[0037] As shown in Figures 2, 5, and 6, the rope holding portion 12 is formed by folding the side end portion of the chute body 10 inward along its longitudinal direction and sewing it in place while covering the fixing rope 13. In this way, the rope holding portion 12 holds the fixing rope 13. The rope holding portion 12 is formed in a cylindrical shape that covers the fixing rope 13, and the chute body 10 has a sewn portion 10a that extends along the rope holding portion 12.

[0038] The fixing rope 13 extends from the upper and lower ends of the rope holding section 12, respectively. Both ends of the fixing rope 13 are formed in a ring shape. The fixing rope 13 is flexible and can be easily folded together with the chute body 10.

[0039] As shown in Figure 3, a support member 15 is attached and fixed to the vertical wall portion 5a, such as window frames and balconies, on the upper floors of the building 5 to support the upper end of the loading chute 1. The support member 15 has a metal rod portion 16, a fixed support portion 17 fixed to one end of the rod portion 16, and a movable support portion 18 that is inserted through the rod portion 16 and can slide.

[0040] The fixed support portion 17 has a first pad 17a that abuts against the inner surface of the vertical wall portion 5a. On the other hand, the movable support portion 18 has a second pad 18a that abuts against the outer surface of the vertical wall portion 5a and a handle 18b. The movable support portion 18 can slide freely along the rod portion 16 when the handle 18b is held, and locks into place and is fixed to the rod portion 16 when the handle 18b is released.

[0041] Thus, with the rod portion 16 positioned to extend horizontally, the position of the movable support portion 18 is adjusted, and the first pad 17a and the second pad 18a firmly attach and fix the support to the vertical wall portion 5a by clamping the vertical wall portion 5a.

[0042] Furthermore, a hole 16a is formed through the rod portion 16. The ring-shaped upper end of the fixing rope 13 is connected to the hole 16a of the support member 15 via a locking device 19. For example, a ring-shaped fitting that can be opened and closed, such as a carabiner, can be used as the locking device 19. This allows the upper end of the chute body 10 to be attached to the vertical wall portion 5a of the upper floor of the building 5.

[0043] On the other hand, the lower end of the chute body 10 can be secured to a hook (not shown) or handle (not shown) of a transport vehicle 7 using a carabiner or other fastening device (not shown).

[0044] As shown in Figures 2 and 4, the unloading chute 1 further includes a stopper 20 that is detachably attached and fixed to the lower end 10b of the chute body 10. The stopper 20 includes a shock-absorbing material (not shown) housed inside a flexible cover 21. The shock-absorbing material can be a cushioning material such as urethane foam. The stopper 20 is formed as a whole in the shape of a plate or block and has, for example, a convex portion 20a that is curved in an arc shape.

[0045] Here, as shown in Figure 5, a first engaging portion 31 is provided on the lower end 10b of the chute body 10, on the surface on which the article A slides. The first engaging portion 31 is made up of, for example, the A side (hook side) of a hook fastener. The first engaging portion 31 is formed in a strip shape that extends in the width direction of the chute body 10 and is positioned along the lower end of the chute body 10.

[0046] On the other hand, as shown in Figures 2 and 4, the stopper 20 has a second engaging portion 32 that detachably engages with the first engaging portion 31. The second engaging portion 32 is made up of, for example, the B-side (loop side) of a hook-and-loop fastener. The second engaging portion 32 is attached and fixed to the convex portion 20a of the stopper 20. The second engaging portion 32 is provided over substantially the entire surface of the convex portion 20a, for example.

[0047] As shown in Figure 2, the chute body 10 is mounted and fixed along the convex portion 20a of the stopper 20 by the engagement of the first engaging portion 31 of the chute body 10 and the second engaging portion 32 of the stopper 20. This configuration causes the chute body 10 to form a U-shaped recessed track S.

[0048] Next, the structure of the lower end portion 10b of the chute body 10 will be described in more detail with reference to Figures 5 to 11. Here, Figures 7 and 8 show the lower portion of the chute body 10 in the deployed state of the deployable portion of the rope holding part 12, with Figure 7 being a front view and Figure 8 being a rear view.

[0049] Figure 9 is a rear view showing the lower portion of the chute body 10 with the lower end portion 10b of the chute body 10 folded back. Figures 10 and 11 further show the lower portion of the chute body 10 with the unfolded portion of the rope holding part 12 folded back, with Figure 10 being a rear view and Figure 11 being a front view.

[0050] As shown in Figure 6, the chute body 10 has a third engaging portion 33 and a fourth engaging portion 34 provided on the back surface of the chute body 10. Here, the back surface is the side of the chute body 10 opposite to the side on which the article A slides.

[0051] The third engaging portion 33 is formed, for example, by the B-side (loop side) of a hook-and-loop fastener. The third engaging portion 33 is located on the back surface of the lower end portion 10b of the chute body 10, and Figure 6 shows an example in which, for example, three third engaging portions 33 are arranged at predetermined intervals in the width direction of the chute body 10.

[0052] The fourth engaging portion 34 is formed, for example, by the A-side (hook side) of a hook fastener. The fourth engaging portion 34 is positioned alongside the third engaging portion 33 on the upper end side of the chute body 10. For example, three fourth engaging portions 34 are arranged at predetermined intervals in the width direction of the chute body 10.

[0053] The dashed line M in Figure 6 represents the valley fold line M of the chute body 10. The valley fold line M is parallel to the lower edge of the chute body 10. The fourth engaging portion 34 is positioned symmetrically with respect to the third engaging portion 33 with respect to the valley fold line M.

[0054] As shown in Figures 5 and 7, the rope holding portion 12 has a deployable portion 12a which is adjacent to the lower end portion 10b of the chute body 10. The deployable portion 12a is configured to be deployable from a folded state, which is folded inward from the chute body 10 as shown in Figure 5, to a laterally outward deployed position as shown in Figure 7.

[0055] As shown in Figure 7, the unfoldable portion 12a is formed in a sheet shape and has a fifth engaging portion 35 provided on the back surface of the unfoldable portion 12a. The fifth engaging portion 35 is made up of, for example, the B side (loop side) of a hook-and-loop fastener. As shown in Figures 5 and 7, the fifth engaging portion 35 is configured to detachably engage with a part of the first engaging portion 31 when the unfoldable portion 12a is in a folded state.

[0056] Furthermore, as shown in Figure 5, the expandable portion 12a has a sixth engaging portion 36 provided on its surface. The sixth engaging portion 36 is, for example, formed by the A-side (hook side) of a hook fastener.

[0057] Furthermore, when the deployable portion 12a is folded and covers the fixing rope 13 (see Figure 5), the sixth engaging portion 36 of the deployable portion 12a and the first engaging portion 31 of the lower end portion 10b of the chute body 10 are both the A-side (hook side) of the hook fastener and are positioned on the front side of the chute body 10. Therefore, the sixth engaging portion 36 of the deployable portion 12a, together with the first engaging portion 31 of the chute body 10, can be detachably engaged with the second engaging portion 32 of the stopper 20.

[0058] When using the above-described unloading chute 1, for example, if the weight of item A is relatively large, the expandable section 12a is folded as shown in Figure 5, and with the stopper 20 attached to the lower end 10b of the chute body 10 as shown in Figure 2, item A is slid onto the item sliding section 11 for unloading. On the other hand, if item A is relatively light, the stopper 20 is removed from the chute body 10, and item A is slid onto the item sliding section 11 for unloading.

[0059] At this time, as shown in Figures 7 to 11, the unloading chute 1 is designed so that the lower end portion 10b of the chute body 10 can be folded back to the other side. That is, as shown in Figure 7, first, the expandable portion 12a of the lower end portion 10b of the chute body 10 is extended outwards to the side.

[0060] Next, as shown in Figures 8 and 9, with the lower end portion 10b of the chute body 10 folded to the back along the valley fold line M, the third engaging portion 33 is detachably engaged with the fourth engaging portion 34. As a result, the first engaging portion 31 is positioned on the back side of the chute body 10, and the lower end portion 10b is maintained in the folded-back position. Furthermore, the unfolded expandable portion 12a can be folded back to the back together with the lower end portion 10b of the chute body 10.

[0061] Next, as shown in Figures 9 and 10, the expandable portion 12a is folded inward, and the fifth engaging portion 35 of the expandable portion 12a is engaged with the first engaging portion 31 of the chute body 10. This allows for a compact, assembled state for use. In this way, as shown in Figure 11, the first engaging portion 31 can be prevented from appearing on the front side of the chute body 10.

[0062] As described above, according to this embodiment, even if the weight of the item A to be unloaded is relatively large and it is not possible to sufficiently reduce the speed of the item A before it reaches the lower end of the item sliding section 11, the item A can be properly stopped by attaching and fixing a stopper containing an impact absorbing material to the lower end 10b of the chute body 10.

[0063] In addition, the stopper 20 in this embodiment is detachable from the chute body 10. Therefore, when the stopper 20 is not needed, such as when unloading relatively lightweight items A or when removing items A that have been stopped by the stopper 20 from the chute body 10, the stopper 20 can be removed from the chute body 10 as appropriate, so that the stopper 20 does not become a physical obstacle to the removal of items A, and the removal work can be carried out smoothly.

[0064] Furthermore, since the chute body 10 is made of a flexible, strip-shaped sheet material, the chute body 10 can be easily and compactly folded by removing the stopper 20.

[0065] In this case, if the sliding object is a heavy object with corners, such as a rectangular parallelepiped, the chute body may suffer significant wear due to concentrated frictional resistance from the corners of the object.

[0066] Furthermore, according to this embodiment, the lower end portion 10b of the chute body 10 is fixed and maintained in a shape that follows the convex portion 20a of the stopper 20, making it possible to form a U-shaped recessed running path S in the chute body 10.

[0067] Therefore, even if item A is a heavy object with corners, such as a rectangular parallelepiped, the frictional resistance that the chute body 10 receives from item A can be effectively reduced. In addition, the U-shaped recessed track S allows for stable downward guidance of item A. In other words, wear on the chute body 10 is suppressed, and item A can be stably slid downward.

[0068] Furthermore, by constructing the chute body 10 using tire cord, it is possible to realize a chute body 10 that is both flexible and highly resistant to wear.

[0069] Here, if the stopper 20 is removed from the lower end 10b of the chute body 10, and the first engaging portion 31 remains positioned on the front side of the chute body 10, there is a risk that the item A may unintentionally get caught on the first engaging portion 31 or that the item A may be damaged by contact with the first engaging portion 31.

[0070] In contrast, according to this embodiment, by folding the lower end portion 10b of the chute body 10 on which the first engaging portion 31 is located to the back side and engaging the third engaging portion 33 and the fourth engaging portion 34, the first engaging portion 31 can be positioned and fixed on the back side of the chute body 10. As a result, when the stopper 20 is not needed, the lower end portion 10b of the chute body 10 can be folded to the back side so that the first engaging portion 31 is not positioned on the front side of the chute body 10, thereby enabling smooth transport of the item A and preventing damage to the item A.

[0071] On the other hand, when the stopper 20 is needed, the third engaging portion 33 is detached from the fourth engaging portion 34, and the lower end portion 10b of the chute body 10, which had been folded back, is returned to the surface side, thereby allowing the stopper 20 to be attached to the lower end portion 10b.

[0072] Furthermore, when attaching the stopper 20 to the lower end 10b of the chute body 10, the deployable portion 12a of the rope holding portion 12 can be folded, and the fixing rope 13 can be held by the deployable portion 12a. On the other hand, when folding the lower end 10b of the chute body 10 to the back, the deployable portion 12a can be folded to the back along with the lower end 10b, and the fixing rope 13 can be held by the lower end portion of the rope holding portion 12 that was adjacent to the deployable portion 12a.

[0073] Therefore, the fixing rope 13 can be properly held at the lower end of the chute body 10 in both the state in which the stopper 20 is attached to the lower end 10b of the chute body 10, and the state in which the stopper 20 is removed and the lower end 10b of the chute body 10 is folded back to the other side.

[0074] Furthermore, by utilizing the first engaging portion 31 used for attaching and fixing the stopper 20, the deployable portion 12a can be fixed to the lower end portion 10b of the chute body 10 in a folded state. Also, by engaging the second engaging portion 32 of the stopper 20 with the sixth engaging portion 36 of the deployable portion 12a that holds the fixing rope 13, the stopper 20 can be attached and fixed not only to the lower end portion 10b of the chute body 10 but also to the fixing rope 13. Therefore, the stopper 20 can be fixed more firmly, and the sliding item A can be reliably stopped.

[0075] In this embodiment, the hook-and-loop fasteners applied to the first to sixth engaging portions 31 to 36 may be configured with their A-side and B-side reversed. Furthermore, other engaging members, such as fasteners like hooks, may be applied to the first to sixth engaging portions 31 to 36. [Industrial applicability]
