Description

PRIORITY CLAIM

[0001] The present application claims priority from the Chinese patent application filed on September 10, 2025, with the Chinese State Intellectual Property Administration, under file number CN202511290450.3 and entitled “A storage trolley for security control items”, the entire contents of which are incorporated by reference into this application. TECHNICAL AREA

[0002] The present invention relates to a storage trolley for security control items. STATE OF THE ART

[0003] Current bus stations, train stations, and airports, including ferry terminals, have two separate screening lanes for luggage and passengers. When traveling, people must place all their belongings on a baggage screening conveyor belt to send them through the baggage screening machine. To ensure passengers are not exposed to unnecessary X-ray radiation, they pass through a separate passenger screening lane. Throughout this entire process, passengers and their belongings are in separate states. After passing through security, passengers search for their belongings at the baggage screening conveyor belt exit. This entire process is hectic and chaotic, and it is common for luggage or personal items to be accidentally mixed up.Solo travelers who spend time in waiting areas often experience many inconveniences when shopping, using the toilet, or sleeping. CONTENTS OF THE INVENTION

[0004] The technical solution by which the present invention solves its technical problem is as follows: A security screening container or a security screening cart, specifically designed and manufactured for passage through the security screening channel, is provided. Since the security screening container is also to be equipped with wheels for easy transport, the term "security screening cart" will be used consistently in the following text for the sake of simplicity.To meet the requirements of baggage screening, the six sides of the security trolley (top, bottom, left, right, front, back) are sealed with a material that does not interfere with X-ray screening, and the doors are locked by the traveler to ensure that items placed in the trolley cannot be accidentally taken by others. The width of the trolley must be compatible with the width of the screening machine, and the length can be specified in various lengths to accommodate travelers with different numbers of pieces of luggage. Luggage is arranged parallel to each other in the trolley to facilitate passage through the screening machine.

[0005] To achieve the above objective, the present invention provides a storage cart for security screening items, comprising a cart body, wherein a receiving compartment for receiving security screening items is provided inside the cart body; a door opening is provided on a surface of the cart body, wherein one end of the door opening and the cart body are rotatably connected by a hinge, the end of the door opening furthest from the hinge is closed and connected to the cart body by a snap lock and is releasably connected to the cart body by a lock; and the non-door-opening parts of the cart body are closed with a material that does not interfere with the X-ray screening.

[0006] The security control vehicle can have two structures depending on the different loading modes.

[0007] Security screening trolley with side loading: The door opening includes a side door, which may be single or double. If there is only one side door, it is located on one side of the trolley body; if there are two, they are located on both sides. The hinge is located on one side of the trolley body near the bottom; the snap lock and latch are located on one side of the trolley body near the top. The security screening trolley has downward-folding side doors on both sides. Once folded down, the traveler can place all their luggage and belongings parallel into the security screening trolley.After loading is complete, the traveler closes the side doors, locks them with the snap lock and secures them with the lock on the wagon body to ensure that the traveler's belongings are not lost, even if they are briefly out of sight.

[0008] Top-loading security screening trolley: The door opening includes a top door located at the top of the trolley body. The top door may have a split structure and be divided into two parts, with the two top doors pivotally connected by a central hinge. The top door of the security screening trolley can be opened in a folded position. The traveler can place all their luggage and belongings into the trolley in parallel. After loading, the traveler folds the top door of the security screening trolley flat, closes it to the trolley body with the snap lock, and secures it with the trolley's lock to ensure that the traveler's belongings are not lost, even if they are briefly out of sight.

[0009] A security checkpoint number is marked in a clearly visible position on the security checkpoint vehicle, and the same number is marked on the key ring to facilitate identification and search.

[0010] The security control vehicle can be equipped with an identification and alarm system, similar to those currently used in car keys. If the key holder moves a certain distance away from the vehicle and someone touches or moves it, the vehicle can sound an alarm to prevent unauthorized movement.

[0011] A child seat can be set up in a suitable position in the security checkpoint vehicle to avoid single travelers with children having to push and look after the child at the same time, and to prevent one from being neglected.

[0012] Four wheels are mounted on the base of the cart body, arranged in a separate structure (the aim being to minimize their influence on the control image). The wheels are divided into front and rear wheels, with two of each. The front wheels are connected to the cart body via wheel mounts, which protrude from one end of the cart body. A rear door is rotatably attached to the cart body at the rear opposite the head. When multiple cart bodies are stacked, the head of the rearmost cart body penetrates the receiving space of the adjacent cart body through the rear door of the front cart body, and the heads of two adjacent cart bodies are spaced apart by the wheel mounts.Similar to a supermarket shopping cart, the top, bottom, and both sides of the security checkpoint trolley are tapered. The head is fixed, and the rear door is a hinged mechanism that folds upwards and forwards. When not in use, the front section of the rear security checkpoint trolley can be slid into the front one, allowing multiple trolleys to be folded and stored compactly.

[0013] Advertising space can be developed on the four side surfaces of the security check vehicle that do not interfere with the checks, in order to increase the utility of the security check vehicle.

[0014] To pass through security, the traveler first places all their belongings in the security trolley, locks it, and pushes it to the baggage screening conveyor belt entrance. The traveler then passes through the passenger screening lane using only the key (travelers with children must also take their child with them) and subsequently retrieves their security trolley containing their belongings at the baggage screening conveyor belt exit. They can then push the trolley themselves into the waiting area or departure hall. Because the corresponding keys remain in the traveler's possession, they don't have to constantly carry their belongings with them during the entire waiting process for the train or plane, even if they fall asleep, go to the kiosk, or need to use the restroom, while still ensuring the security of their belongings.Only shortly before the train journey or boarding does he open the security checkpoint and retrieve his belongings. Throughout the entire check-in process, the safety of his belongings is guaranteed, even if he leaves them unattended briefly, and the entire waiting process for the train or flight can proceed smoothly.

[0015] The advantageous effect of the present invention is that, throughout the entire check-in process, the security screening cart ensures that the traveler, although relinquishing control of their belongings, can still guarantee their security, since the belongings are locked in the cart and the corresponding keys remain in the traveler's possession. The traveler can thus ensure the security of their belongings throughout the entire check-in and waiting process for the train or plane, allowing the entire process to proceed smoothly and calmly.

[0018] With reference to the drawings, the present invention provides a storage trolley for security screening items, comprising a trolley body 7, wherein a receiving compartment for receiving security screening items is provided inside the trolley body 7; a door opening is provided on a surface of the trolley body 7, wherein one end of the door opening and the trolley body 7 are rotatably connected by a hinge 4, the end of the door opening furthest from the hinge 4 is closed and connected to the trolley body 7 by a snap lock 2 and is releasably connected to the trolley body 7 by a lock 1; and the non-door-opening parts of the trolley body are closed with a material that does not interfere with the X-ray screening. In use, when passing through security, the traveler first places all their belongings into the receiving compartment inside the trolley body 7.He then controls the door opening to rotate it around the axis of hinge 4, guides the door opening to the trolley body 7, connects it to the trolley body 7 using the snap lock 2, and locks it to the trolley body 7 using the lock 1. After locking, he pushes the security trolley to the entrance of the baggage screening conveyor belt. The passenger then passes through the passenger screening lane using only the key (passengers with children must also take their child with them) and subsequently retrieves their security trolley with their deposited items at the baggage screening conveyor belt exit. They can then push the trolley themselves into the waiting area or departure hall.Since the corresponding keys remain in the traveler's possession, they can ensure the security of their belongings throughout the entire waiting process for the train or plane, even if they fall asleep, go to the kiosk, or need to use the restroom. Only shortly before the train journey or boarding do they open the security check cart and retrieve their belongings. The security of the traveler's belongings is guaranteed throughout the entire check-in process, even if they are briefly left unattended, allowing for a relaxed and stress-free wait for the train or plane.

[0019] The security control vehicle can have two structures depending on the different loading modes:

[0020] Security check cart with top-loading mode: With reference to Fig. 1 The door opening includes an upper door 6, the upper door 6 being located on the top of the cart body 7; the upper door 6 may have a split structure and be divided into two parts, the two upper doors 6 being rotatably connected by a central hinge 5. The rear of the security screening cart is a rear door 3 that can be folded upwards to allow the rear security screening cart to be driven in. A foldable small seat is attached to the rear door 3. This part of the structure is completely identical to the rear and small seat structure of a supermarket shopping cart and is not described further here. The top of the cart body 7 has an upper door 6 that can be folded upwards. Since the door opening is relatively wide, the upper door 6 consists of two parts connected in the middle by a central hinge 5.One side of the upper door 6 is attached to the top of the carriage body 7 by a hinge 4. By opening the upper door 6, the passenger's belongings can be placed inside the carriage. Once finished, the upper door 6 is lowered, laid flat on top of the carriage body 7, tightly closed to the carriage body 7 by means of the snap lock 2, and locked with the lock 1. The floor, sides, and end of the carriage are completely enclosed, providing a degree of rigidity, but do not interfere with the X-ray screening.As can be seen in the part indicated by AA, the snap lock 2 is a hook-rail structure, the hook rail being attached to the reinforcing rib 13 of the upper door 6 and engaging with the upper edge bead 10 of the carriage body 7 by means of a mechanical elastic locking mechanism; as can be seen in the part indicated by BB, the bolt 9 of the lock 1 attached to the upper door 6 rotates with the help of the key into a position below the upper edge bead 10, so that the upper door 6 cannot be opened upwards. The handle part of the carriage is omitted and not shown.

[0021] Security check cart with side loading mode: With reference to Fig. The door opening includes a side door 20, which can be configured as either single or double doors. If it is configured as a single door, it is located on one side surface of the cart body 7; if it is configured as a double door, the side doors 20 are located on both side surfaces of the cart body 7. The hinge 4 is located on one side of the side surface of the cart body 7 near the bottom; the snap lock 2 and the lock 1 are located on one side of the cart body 7 near the top. The rear of the security screening cart is a rear door 3 that can be folded upwards to allow the rear security screening cart to be driven in. A foldable small seat is attached to the rear door 3. This part of the structure is completely identical to the small seat structure of a supermarket shopping cart and is not described further here.A side door 20 is provided on one side of the trolley body 7 and can be lowered. The side door 20 is attached to the side of the trolley body 7 by a hinge 4. After lowering the side door 20, items can be placed into the trolley from the side. After raising the side door 20, it is tightly closed to the trolley body 7 by means of the snap lock 2 and locked with the lock 1. The bottom, top, end, and other, unopened side of the trolley are completely closed, have a certain rigidity, but do not interfere with the X-ray inspection. The left or right upright edge of the trolley's rear is extended upwards to form a bar 21, the principle being that this does not impede the stacking of multiple trolleys. A plate 22 is attached to the bar 21, on which the trolley number is printed, corresponding to the number on the key ring.The sign 22 utilizes the high-mounted pole 21 so that the passenger can recognize their locked and occupied carriage from a great distance. Since this has no technical significance, this structure is not mandatory but merely a suggestion. The sign 22 can also be attached to other conspicuous positions on the carriage. As can be seen in the part indicated by CC, the snap lock 2 is a hook-rail structure, with the hook rail attached to the upper reinforcing rib 13 of the side door 20 and engaging with the upper rim 10 of the carriage body 7 by means of a mechanical elastic locking mechanism; as can be seen in the part indicated by DD, the bolt 9 of the lock 1 attached to the side door 20 rotates with the aid of the key into a position within the upper rim 10, so that the side door 20 cannot be lowered outwards.The other side surface of the car body 7 may also have a side door 20 or may not have a door opening, depending on the results of the application tests.

[0022] In Fig.3 Four wheels are attached to the base of the cart body 7, the four wheels being arranged in a separate structure on the base of the cart body 7. Given that the cart must pass the inspection without obstruction, the four wheels are mounted under the cart in a separate structure on the cart floor, with the wheel mounts designed to avoid obscuring the central part of the cart as much as possible (the aim is to minimize any interference with the inspection image). In some embodiments, the wheels are divided into front wheels 31 and rear wheels 32, with two of each. The front wheels 31 are connected to the cart body 7 via wheel mounts, which protrude from an end 33 of the cart body 7. A rear door 3 is rotatably attached to the rear of the cart body 7 opposite the end 33.When several carriage bodies 7 are stacked, the head 33 of the rear carriage body penetrates the receiving space of the front carriage body through the rear door 3 of the adjacent and front carriage bodies, and the heads 33 of two adjacent carriage bodies are spaced apart by the wheel mounts. The two front wheels can be designed as straight-running wheels or as swivel casters. The two front wheels must project a certain distance forward beyond the carriage to ensure that, when stacked, the head 33 of the rear carriage is located in the upward space of the front carriage. The rear wheels are designed as swivel casters and are mounted separately on the two rear sides of the carriage.

[0023] Based on practical application tests, improved cart concepts may be developed. Therefore, the core objective of this application is to offer travelers a solution that provides a temporary storage container for personal belongings; facilitates security screening; makes pushing easier; and ensures the security of the items through locking. Or, put another way: to offer travelers a solution in the form of a storage cart for items subject to security screening.
