Description

[Technical Field]

[0001] The present invention relates to a carrier for a dolly, and more particularly to a carrier for a dolly for simultaneously transporting a plurality of dollies on which loads are placed. [Background technology]

[0002] Conventionally, dollies have been used to transport multiple containers (hereinafter referred to as cargo). These dollies have a simple structure in which wheels are attached to a platform on which the cargo is placed, and in cases where contact with the cargo is undesirable due to hygiene considerations or the like, a detachable handle or the like may be attached for transportation, but normally no handle or the like is provided, and the current situation is that the loaded containers are transported by pushing them.

[0003] Therefore, it is relatively difficult to simultaneously move multiple dolly carts loaded with cargo, regardless of whether they have detachable handles, etc. Although there are dollies that allow multiple dollies to be connected together, making it easier to move multiple dollies, in such cases, the loaded containers must first be removed from the dolly before they can be detached, which is inconvenient.

[0004] To solve the above problems, the applicant has developed a dolly carriage carrier and filed a patent application (see Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2019-182080 Summary of the Invention [Problem to be solved by the invention]

[0006] In recent years, dollies have also come to be used in intermediate distribution centers, etc. At intermediate distribution centers, for example, many plastic containers containing cargo sorted by destination are handled on a daily basis, and many dollies are used to transport these plastic containers.

[0007] If dolly trolley transport devices were to be introduced into such intermediate distribution centers, it would be expected that a considerable number of transport devices would be required in proportion to the number of dolly trolleys.However, intermediate distribution centers are often relatively small spaces, and it would be difficult to secure new space to store these transport devices.

[0008] Therefore, the object of the present invention is to provide a trolley carrier that can store multiple trolley carriers in a smaller space. [Means for solving the problem]

[0009] The present invention is a transport device for a cart having a platform on which a load is placed and wheels attached to the platform, characterized in that it comprises a main body that can be inserted under the platform and is foldable, a locking part that is attached to the main body and can lock the cart, and a support part that is connected to the main body, and the support part is configured to support the main body in a folded state.

[0010] The present invention may also be configured such that a holder is provided on the support portion, and the holder is provided to hold the main body portion in the folded state and to hook the main body portion to the support portion. The present invention may also be configured such that a tiltable grip portion is provided, and the grip portion is hookable to the support portion via a hook. The present invention may also be configured such that the main body portion is rotatably connected to the support portion. [Effects of the Invention]

[0011] This invention provides a trolley carrier that can store multiple trolley carriers in a smaller space by making the main body foldable and allowing the main body to be supported by a support part when folded. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] An embodiment of the present invention will be described with reference to Figs. 1 to 9, taking a dolly carriage as an example. First, the configuration of the carriage 1 will be described. The carriage 1 (hereinafter referred to as carriage 1) is a carriage that can simultaneously transport multiple carriages, for example, dolly carriages D (hereinafter referred to as carriages D). The carriage is not limited to the dolly carriage D, and the present invention can be applied to any similar carriage with wheels on the mounting base, such as a car carriage (not shown).

[0014] For example, the dolly D has a platform D1 on which a plurality of loads, for example, plastic containers (not shown), can be placed, and wheels D2 are provided on all four sides of the bottom surface of the platform D1.

[0015] The carrier 1 comprises a main body 2 and a support part 3, and in this embodiment, a grip part 4. The main body 2 is provided so as to be insertable below the mounting base D1 of the cart D, is foldable, and has a locking part 5. Furthermore, the length of the main body 2 in the insertion direction A when extended is a length that allows multiple carts D to be lined up in parallel, for example, a length that allows three carts D to be lined up in parallel in the short direction. Note that the number of carts D that can be lined up in parallel and the direction from which the cart D can be inserted can be selected as appropriate.

[0016] In this embodiment, the main body 2 is made up of a rear frame 6 and a front frame 7, and is foldable in half by connecting the rear frame 6 and the front frame 7 with a hinge 8. The front frame 7 has a locking portion 5, a handle 9, and wheels 10. The handle 9 is provided so that it can be grasped when folding the main body 2, and is embedded in the front frame 7 so as not to get in the way when inserting the main body 2 below the mounting table D1.

[0017] One end of the rear frame 6 is connected to the front frame 7, and the other end is rotatably connected to the support part 3 with a hinge 11 as a fulcrum. The rear frame 6 is also provided with a through-hole 12 that allows a holder 16, which will be described later, to pass through. The main body part 2 is not limited to being foldable in two, but can also be foldable in three or more folds.

[0018] The locking portion 5 is provided so as to be able to lock the cart D when the main body 2 is inserted below the mounting table D1. In this embodiment, the locking portion 5 is retracted when the main body 2 is inserted below the mounting table D1 so as not to get in the way.

[0019] Specifically, the locking portion 5 functions as a so-called return, and has an inclined surface 13 and a locking surface 14. When the platform D1 of the cart D abuts against the inclined surface 13, the platform D1 presses down the locking portion 5 together with the arm 15 supporting the locking portion 5, allowing the cart D to slide smoothly, but if an attempt is made to slide the cart D from the side of the locking surface 14, the platform D1 is locked by the locking surface 14 and will not slide any further.

[0020] The support part 3 is provided to support the main body part 2 when the main body part 2 is folded. In this embodiment, the support part 3 is provided with a holder 16, which holds the main body part 2 in the folded state and hooks the main body part 2 to the support part 3. Specifically, when the main body part 2 is folded, the holder 16 is inserted into the through hole 12 and hooked onto a hook part 17 provided on the front frame 7. In this embodiment, the support part 3 has wheels 18 attached to both ends of its lower part.

[0021] The grip part 4 is provided so that the user can grip it when moving the carrier 1. In this embodiment, the grip part 4 is provided so as to be tiltable, and is provided so as to be able to be hung on the support part 3 via a hook 19. Specifically, the grip part 4 is pivotally supported by wheel parts 18 provided on both sides of the grip part 4, thereby enabling it to tilt. A shaft part 20 for this purpose is provided through the grip part 4.

[0022] In this embodiment, the gripping part 4 is provided with a hooking part 21 that is capable of engaging with the hooking device 19, and by hooking the hooking device 19 to the hooking part 21, the gripping part 4 is hooked to the support part 3. A lever 22 is attached to the gripping part 4, and the lever 22 is connected to the locking part 5 via a wire (not shown). By operating the lever 22, the locking part 5 is retracted, and the cart D can be detached from the transport device 1.

[0023] Wheel section 18 has wheels 23, which, together with wheels 10, are provided as a means for moving carrier 1. In this embodiment, wheel section 18 is provided with protrusions 24, which are arranged to come into contact with platform D1 when carrier 1 is used to transport cart D, and serve as a pushing member for pushing cart D. It is also possible to use support section 3 as a pushing member without providing protrusions 24.

[0024] Furthermore, in this embodiment, the size of wheels 10 and 23 is such that when main body 2 is inserted under mounting base D1 of trolley D, wheels D2 of trolley D touch the ground and wheels 10, 23 and wheels D2 rotate together, and main body 2 and mounting base D1 are not in contact, so that the weight of the load is not placed on main body 2 even after insertion, but is placed on trolley D.

[0025] Next, a method for transporting the dolly D using the transporting device 1 will be described. (1) The carrier 1 is stored in a predetermined storage location with the main body 2 folded.

[0026] (2) The holder 16 is removed from the engaging portion 17 of the carrier 1, and the main body 2 is released from the engagement of the holder 16. Then, the handle 9 is gripped, for example, to stretch the main body 2.

[0027] (3) The main body 2 is inserted under the mounting base D1 of the cart D to be transported. Once the required number of carts D have been inserted, the cart D is moved along with the carrier 1, allowing multiple carts D to be transported simultaneously.

[0028] At this time, a load (not shown) may be placed on the platform D1 of the cart D in advance, or the load may be placed on the platform D1 after the main body 2 has been inserted. Also, the carrier 1 may be moved by pushing it or by pulling it.

[0029] When the carrier 1 is to be moved by pushing, the holding portion 4 is hooked to the support portion 3, and the cart D is pushed forward by the protrusion 24 (or the support portion 3), thereby allowing the carrier D to be transported. When the carrier 1 is to be moved by pulling, the holding portion 4 is tilted, and the cart D is pushed forward by the locking surface 14 of the locking portion 5, thereby allowing the carrier D to be transported.

[0030] Therefore, in the carrier 1 of this embodiment, the main body 2 is foldable and the main body 2 in the folded state is supportable by the support part 3, making it possible to store multiple trolley carriers in a smaller space.

[0031] Although the present invention has been described above using the above embodiment, the present invention is not limited to the above embodiment and can be modified as appropriate within the scope of the invention.
