Description

Technical Field

[0001] The present invention relates to a guide and limit assembly, and in particular to a guide and limit assembly for guiding and limiting a container to be loaded into a cabin, which is convenient for guiding the movement of loading and unloading containers of different sizes and avoiding collision with cabin doors, and is used to improve the convenience of using integrated multi-loading solutions Background Art

[0002] In modern freight, in order to avoid the process of manually moving bulk goods one by one, containers or pallets (collectively referred to as containers) are generally used to transport goods to improve transportation efficiency.

[0003] Air cargo is an important part of modern logistics, providing safe, fast, convenient and high-quality services. In air cargo, in order to avoid manually loading bulk goods onto the plane one by one, air containers, also known as containers, are generally used. Currently, containers used in aviation all adopt the standards specified by IATA, and the commonly used ones are: AKE, PAG, PMC, PBJ, etc. Containers of different standards have different size specifications.

[0004] The large size and weight of aviation containers make them difficult to move and difficult to control in the process of loading and unloading from the cabin. During the loading and unloading process of the container, in order to move the container to the predetermined position quickly and conveniently, it is necessary to install a guide limit device at a specific position in the cabin to constrain the moving direction of the container during loading and unloading in the cabin.

[0005] Existing restraint and locking devices for cabins are used to restrain and release containers, but have no function of limiting and guiding the movement of containers.

[0006] In addition, it is also necessary to consider that the loading and unloading positions of different standard-sized containers in the cabin are inconsistent, the installation positions of the required guide and limit devices are also different, and redundant guide and limit devices are likely to block and interfere with the loading process of other containers.

[0007] Therefore, there is an urgent need to propose a guiding and limiting device that has a simple structure, is easy to install, requires little space, and does not pose a risk of interference with the container, so as to allow containers of different standard sizes to be loaded and unloaded in the cabin. Summary of the invention

[0008] In view of the above problems in the prior art, the inventor provides a guiding and limiting assembly, which guides the container to move to a predetermined position during the loading and unloading process of the container in the cabin, and solves the problem of guiding the door of containers of different sizes entering and exiting the cabin.

[0009] In a first example of the guide and limit assembly, the guide and limit assembly includes: a base, which is fixed to a predetermined installation position in the cabin; and a rolling assembly, which is detachably fixed to the base, and the rolling assembly includes a rolling body capable of rotating around a first axis, and when the rolling assembly is fixed to the base, the first axis is not parallel to the plane of the floor of the cabin.

[0010] In the second example of the guide and limit assembly, the first example is optionally included, the base is provided with a base fixing portion on the side wall, the installation position is at the door of the cabin, and there is a fixing portion corresponding to the base fixing portion on the floor at the door of the cabin.

[0011] In a third example of the guide and limit assembly, optionally including one or more of the first and second examples, the base is provided with a base fixing portion on the bottom wall, the installation position is in the middle of the cabin of the cabin, and there is a floor fixing portion corresponding to the base fixing portion on the floor in the middle of the cabin of the cabin.

[0012] In a fourth example of the guide and limit assembly, optionally including one or more of the first to third examples, the rolling assembly further includes a support, and the base further includes a seat portion, which is at least partially shaped to match the support and at least partially accommodates the support.

[0013] In the fifth example of the guide and limit assembly, one or more of the first to fourth examples are optionally included, the guide and limit assembly also includes a pin shaft and a cotter pin, the support of the rolling assembly also includes a first through hole corresponding to the pin shaft, and the side wall of the accommodating space of the seat portion of the base also includes a second through hole corresponding to the pin shaft, wherein the pin shaft can pass through the first through hole and the second through hole and thus pass through the support and the seat portion, and wherein the pin shaft has a pin hole corresponding to the cotter pin.

[0014] In the sixth example of the guide and limit assembly, one or more of the first to fifth examples may be optionally included, the rolling assembly further includes a rotating shaft, the rotating shaft and the support are fixed to each other, the rotating shaft extends along the first axis A, and the rolling body is sleeved on the rotating shaft.

[0015] In a seventh example of the guide and limit stop assembly, which optionally includes one or more of the first to sixth examples, the rolling assembly includes a bearing, and the rolling element is rotatably connected to the rotating shaft via the bearing.

[0016] In the eighth example of the guide and limit assembly, which optionally includes one or more of the first to seventh examples, the rolling assembly includes a top cover, which is annular and has a central hole for the rotating shaft to pass through, and the top cover covers the top of the rolling body.

[0017] In order to facilitate the loading and unloading of containers, the present invention designs a guide and limit assembly of the present application, so that the heavy and large-sized aviation containers can move in the correct direction and save time and effort. In addition, it is also necessary to consider that there are containers with different standard sizes, their loading and unloading positions are inconsistent, and the guide and limit device cannot interfere with the loading and unloading of containers of other sizes. Based on this, a detachable guide and limit assembly of the present application is designed to facilitate the quick disassembly of containers of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] First of all, the present invention mainly relates to a guide and limit device related to loading and unloading of a container into a cabin in any transportation field. In particular, the present invention relates to the field of air cargo, for example, to a guide and limit device for loading an air container into a cabin of a cargo aircraft, but is not limited thereto.

[0051] As used herein, the term “fixed” is intended to describe a component that is connected to another component and is capable of maintaining a constant relative position to each other so that forces, torques, etc. can be transferred from one component to the other.

[0052] "Form fit" in the context of the present invention is intended to describe that the shape of at least a portion of one component and the shape of at least a portion of another component can fit with each other. The "form fit" does not require complete shape matching, but can be partial shape matching. For example, one component is convex and can be received in a curved recessed portion of another component, or a key of one component can be partially received in a groove of another component. As long as there are force transmission paths, no matter how many, they are within the scope of the present invention.

[0053] Directional terms used herein, such as "top", "bottom", "upper", "lower", "inner", "inward", "outer", and "outward", are used to assist in describing the present invention according to the orientation of the embodiments shown in the drawings. Unless otherwise specified, such as "horizontal direction", "direction of gravity", etc., directional terms are not absolute up, down, horizontal, vertical, etc., and should not be interpreted as limiting the present invention to any particular direction.

[0054] The term "axial" as used herein refers to a direction extending generally along an axis of symmetry, a central axis, an axis of rotation, or the elongated direction of a specific component or system. For example, an axially extending feature of a component may be a feature extending generally along a direction parallel to the axis of symmetry or the elongated direction of the component. Further, for example, axially aligned components may be configured so that their axes of rotation are aligned. Similarly, the term "radial" as used herein refers to a direction generally perpendicular to a corresponding axial direction. For example, a radially extending structure of a component may extend generally at least partially along a direction perpendicular to the longitudinal or central axis of the component. The term "circumferential" and variations thereof as used herein refer to a direction extending around the periphery of an object, or around an axis of symmetry, an axis of rotation, a central axis, or the elongated direction of a specific component or system.

[0055] As used herein, the terms "comprising," "having," "including," and variations thereof are intended to serve as open-ended transitional phrases, terms or words requiring the presence of specified elements / steps and also allowing for the presence of other elements / steps.

[0056] In the present invention, unless explicitly stated to the contrary, the terms "first", "second", etc. are not intended to indicate any difference in order, position, quantity or importance, but are merely used as labels to distinguish different positions and components, and to distinguish one element, component, region and / or position from another element, component, region and / or position.

[0057] In a non-limiting example, the guide and limit assembly 10 of the present invention is fixed to a predetermined installation position 3 based on the size of the container 2 to be loaded and unloaded in the cabin 1, and is used to guide and limit the movement and motion direction of the container 2. Each installation position 3 can correspond to different sizes of conventional containers 2.

[0058] In a non-limiting example, the guide and limit assembly 10 of the present invention includes a base 20 and a rolling assembly 30 that are independent and detachable from each other, wherein the base 20 is arranged at a predetermined installation position 3, and the rolling assembly 30 is used to guide and limit the movement and motion direction of the container 2.

[0059] The present invention will be further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0060] A coordinate system is provided in the figures for reference, the z-axis may be the vertical axis (e.g., perpendicular to the plane of the cabin floor), the x-axis may be the longitudinal axis and the y-axis may be the transverse axis (e.g., the xy plane is parallel to the plane of the cabin floor).

[0061] When referring to directions, a positive direction may refer to the direction of the arrows for the y-, x-, and z-axes, and a negative direction may refer to the opposite direction of the arrows for the y-, x-, and z-axes. A solid circle may represent arrows and axes facing toward or normal to the view.

[0062] Figure 1 A top view schematically shows a predetermined installation position 3 of a container 2 in a cabin 1 according to an embodiment of the present invention.

[0063] like Figure 1 As shown, the container 2 of standard size may include a first container 2a and a second container 2b. It can be understood that the type of container 2 applicable to the present invention is not limited thereto, but may be of other sizes.

[0064] In order to ensure that the container 2 is in the correct direction during the movement, the predetermined installation position 3 can be used for the loading and unloading requirements of two containers of different sizes 2a and 2b, and the first installation position 3a and the second installation position 3b corresponding to the first container 2a and the second container 2b can be provided at the door of the cabin 1. The movement of the corresponding container in the y direction is limited at the guide limit assembly 10 to ensure that they can only move along the x direction at the guide limit assembly 10 during the loading and unloading process.

[0065] In addition, the predetermined installation position 3 may also include a third installation position 3c and a fourth installation position 3d in the middle of the cabin 1. It can be understood that the positions of these installation positions 3 are not limited to this, but may be other positions set according to actual needs.

[0066] In a non-limiting example, the guide limiter assembly 10 of the present invention includes an independent base 20, and the base 20 includes at least one base fixing portion 21 for installation at a predetermined installation position 3. The base fixing portion 21 may be, but is not limited to, a fastener hole, a snap-fit ​​connection structure, etc. The same base 20 may be installed at all installation positions 3. Figure 1As shown, the base 20 can be installed at the first position 3a to the fourth position 3d.

[0067] Figure 2 A perspective view of a guide and limiting assembly 10 according to an embodiment of the present invention is schematically shown.

[0068] like Figure 2 As shown, the base fixing portion 21 can be a fastener hole at the side wall of the base 20, and there is a fixing portion corresponding to the base fixing portion 21 on the floor of the installation position 3 at the hatch of the cabin 1, which is also in the form of a fastener hole. It can be connected by corresponding fasteners, such as a set of bolts, washers and nuts.

[0069] In addition, the base fixing part 21 can be a fastener hole at the bottom wall of the base 20, and there is a floor fixing part corresponding to the base fixing part 21 on the floor of the installation position 3 at the middle of the cabin 1, which is also in the form of a fastener hole. It can be connected by corresponding fasteners, such as a set of bolts, washers and nuts.

[0070] In a non-limiting example, the guide and stop assembly 10 of the present invention includes a rolling assembly 30, and the rolling assembly 30 is detachably fixed to the base 20. Figure 1 As shown, when loading and unloading the first container 2a, for example, a set of rolling assemblies 30 can be detachably fixed to the base 20 at the first position 3a, and only the base 20 is installed at the second position 3b without the rolling assemblies 30 to avoid interference with the first container 2a.

[0071] Preferably, the present invention can set the number of bases 20 of the guide limit assembly 10 according to the number of types of loading and unloading containers 2, and only one set of roller assemblies 30 is required. When not loading and unloading, the roller assembly 30 is always placed in a designated base 20 in the cabin, and there is no need to configure the roller assembly 30 separately when transporting through the station, so that the purpose of taking and using is achieved.

[0072] In this embodiment, the rolling assembly 30 includes a rolling body 31 rotatable about a first axis A. The rolling body 31 may be a roller, a roller shaft, etc., which can flexibly rotate about an axial direction and has an outer peripheral surface for direct contact with the container 2 .

[0073] The container 2 is mainly used in contact with the rolling body 31, so the rolling body 31 is a relatively vulnerable consumable part. The detachable rolling body 31 is easy to repair and replace, and its structure is simple and easy to manufacture.

[0074] like Figure 1As shown, the rolling body 31 contacts the container 2 to guide the container 2 to move in the x direction in and out of the cabin, and blocks the container 2 from moving in the y direction intersecting with the x direction, wherein the xy plane is parallel to the plane where the floor of the cabin is located.

[0075] In this embodiment, when the rolling assembly 30 is fixed to the base 20, the first axis A is parallel to the z-axis to guide the container 2 to move in the x-direction entering and exiting the cabin, and to prevent the container from moving in the y-direction intersecting the x-direction.

[0076] Figure 3 An exploded view of a guide and limiting assembly 10 according to an embodiment of the present invention is schematically shown.

[0077] In this embodiment, the base 20 may further include a seat portion 22, and the rolling assembly 30 may include a support 32, so that the rolling assembly 30 is detachably fixed to the base 20. The seat portion 22 of the base 20 is at least partially shaped to fit the support 32 of the rolling assembly 30 and at least partially accommodates the support 32.

[0078] like Figure 3 As shown, the receptacle portion 22 of the base 20 is designed as a receiving space of a hollow part of a rectangular parallelepiped with rounded edges, and the length of the receiving space in the x-direction and the y-direction is greater than the length in the z-direction. The support 32 of the rolling assembly 30 is correspondingly designed as a rectangular parallelepiped with rounded edges. Here, the support 32 and the receptacle portion 22 can be slightly clearance-matched to facilitate the matching and disassembly process of the base 20 and the rolling assembly 30. Optionally, the rounding angle of the support 32 can be greater than the rounding angle of the receptacle portion 22.

[0079] It is understood that the shape of the accommodating space of the receiving portion 22 of the base 20 and the support 32 of the rolling assembly 30 is not limited thereto, but may be other shapes, such as a racetrack shape, an ellipse, a trapezoid, a parallelogram, etc., as long as they can be shaped to facilitate the matching and disassembly process of the base 20 and the rolling assembly 30. In addition, in an embodiment not shown, the receiving portion 22 of the base 20 and the support 32 of the rolling assembly 30 may also be a shape-matching snap-fit ​​connection structure, which is detachably fixed to each other through a snap-fit ​​connection.

[0080] In this embodiment, the guide and limiting assembly 10 further includes a pin shaft 40 and a cotter pin 50 .

[0081] like Figure 3As shown, the support 32 of the rolling assembly 30 further includes a first through hole 41 corresponding to the pin 40, and the side wall of the accommodating space of the receiving portion 22 of the base 20 further includes a second through hole 42 corresponding to the pin 40. The pin 40 can pass through the first through hole 41 and the second through hole 42 and thus pass through the support 32 and the receiving portion 22. In addition, the pin 40 has a pin hole 43 corresponding to the cotter pin 50 in the section protruding through the support 32 and the receiving portion 22, as will be described in detail below. Figure 4 Shown in.

[0082] When installing the rolling element 31, the pin 40 passes through the through holes 41, 42 of the support 32 and the receiving portion 22, and is fixed by inserting the split pin 50 into the pin hole 43, and the guide limiter assembly 10 is assembled. When disassembling the rolling element 31, the split pin 50 is removed, the pin 40 is removed, and the rolling element 31 and the support 32 can be removed from the receiving portion 22.

[0083] In this embodiment, the pin 40 extends in the x-direction. It is understood that the direction of the pin 40 is not limited thereto, and the positions of the first through hole 41 and the second through hole 42 are also not limited thereto, but can be any position that can detachably fix the seat portion 22 of the base 20 and the support 32 of the rolling assembly 30. In addition, in an embodiment not shown, the seat portion 22 of the base 20 and the support 32 of the rolling assembly 30 can also be detachably connected by a snap-fit ​​connection structure or a fastener.

[0084] In this embodiment, the rolling assembly 30 may include a rotating shaft 33 extending along the first axis A, the rolling body 31 sleeves the rotating shaft 33, and the support 32 and the rotating shaft 33 are detachably fixed to each other. In this embodiment, the rotating shaft 33 is, for example, an elongated bolt.

[0085] In this embodiment, the rolling assembly 30 may include a bearing 34 , and the rolling body 31 is rotatably connected to the rotating shaft 33 via the bearing 34 .

[0086] Preferably, if Figure 3 As shown, the bearing 34 may be a cylindrical roller bearing and is rotatably connected to the rotating shaft 33. The bearing 34 is sleeved on the rotating shaft 33, and then the rolling body 31 is sleeved on the bearing 34. It can be understood that the form of the bearing 34 is not limited thereto, and may also be other bearings suitable for rotation.

[0087] Figure 4 Another perspective view of the guide and limiting assembly 10 according to the embodiment of the present invention is schematically shown.

[0088] In this embodiment, the rolling assembly 30 may include a top cover 35, which is disposed on the top of the rolling element 31 and the bearing 34. The top cover 35 is annular and has a central hole for the rotating shaft 33 to pass through. The top cover 35 is used to cover the top of the rolling element 31 and acts as a dust cover to prevent dust and dirt from entering the rolling assembly 30.
