Abstract
Description
Technical Field
[0001] This utility model relates to the field of food cart technology, and in particular to a multi-functional food cart for children to serve themselves. Background Technology
[0002] In the application scenario of children serving their own meals, existing multi-functional food carts have functional limitations and design flaws, and cannot fully meet the needs of use. Specifically:
[0003] 1. Defects in the countertop structure
[0004] The countertops of existing food carts are usually too narrow, and due to insufficient width, they cannot completely cover the bottom of the plates. Furthermore, during the process of children serving food, food easily spills through the gap between the countertop and the cart, causing not only food waste but also increasing the cleaning burden.
[0005] 2. Limitations of dish basket storage
[0006] The existing bowl baskets in the classroom rely on a dedicated table for placement, separate from the food carts, resulting in a lack of integrated design for the food service environment. On the one hand, children have to move back and forth between the food cart and the bowl basket table to retrieve their utensils, making the process inconvenient. On the other hand, the scattered storage method takes up extra space and increases the risk of children bumping into things and getting injured. Some teachers have suggested an integrated design for the bowl baskets and food carts, but the current food carts do not address this issue.
[0007] In summary, existing multi-functional meal carts have room for improvement in terms of ease of operation, overall functionality, and safety. Structural optimization and functional integration are urgently needed to enhance the experience and efficiency of children's self-service meal preparation. Therefore, we have developed a new multi-functional self-service meal cart for children. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0036] Please see Figure 1-5 This utility model provides a technical solution: a multi-functional self-service meal cart for toddlers, comprising: a base plate 1, a top plate 2, a push handle 3, several lunchbox holders 4, two tabletop components 5, a limiting strip 6, a pull-out component 7, four casters 8, and four support rods 9. The top plate 2 has a hot water tank 10 at its top for adding hot water at a temperature of 40-50℃ (not too high to prevent scalding). The push handle 3 is fixedly connected to one side of the top of the top plate 2. Several lunchbox holders 4 are fixedly connected between the upper ends of the two inner walls of the hot water tank 10. The two tabletop components 5 are symmetrically arranged on both sides of the top plate 2. The limiting strip 6 is fixedly connected to the bottom of the top plate 2 on the side away from the push handle 3. The pull-out component 7 is located on one side of the bottom of the top plate 2. The four casters 8 are fixedly installed at the four corners of the bottom of the base plate 1. The casters 8 are anti-accidental contact brakeable casters. The four support rods 9 are fixedly connected at the four corners between the base plate 1 and the top plate 2.
[0037] The tabletop component 5 includes a tabletop 51, the length of which is the same as that of the top plate 2. The two corners furthest from the top plate 2 are rounded to prevent blunt angle injuries to young children. The tabletop 51 and the top plate 2 are connected by two hinges 52. The hinges 52 are Peryon right-angle self-locking folding hinges. For details, please refer to the Taobao link: [Taobao] 90-degree right-angle folding hinge bracket hardware hinge accessories stainless steel flip plate self-locking support hinge opening and closing. The working principle and structure will not be described here. Two first slide bars 53 and two second slide bars 54 are symmetrically arranged on one side of the tabletop 51, with the two second slide bars 54 distributed between the two first slide bars 53.
[0038] The two first sliders 53 are used to fit the plate. The bottom of the plate has two grooves that fit the first sliders 53. This way, the grooves at the bottom of the plate can slide on the first sliders 53, making it less likely for the plate to slip off. Similarly, the two second sliders 54 are used to fit the bowl. The bottom of the bowl has two grooves that fit the second sliders 54. This way, the grooves at the bottom of the bowl can slide on the second sliders 54, making it less likely for the bowl to slip off. This guides the plate to slide smoothly and is suitable for the force of a child's operation.
[0039] The pull-out assembly 7 includes two L-shaped strips 71, which are fixedly connected to the bottom of the top plate 2 in a mirror-symmetrical manner. A limiting strip 6 is located between one end of the two L-shaped strips 71, and a sliding cavity 72 is formed between the two L-shaped strips 71. A pull-out plate 73 is slidably connected within the sliding cavity 72. A baffle 74 is fixedly connected to one end of the pull-out plate 73, and a stop strip 75 is fixedly connected to the other end of the pull-out plate 73. The top surface of the stop strip 75 is higher than the bottom surface of the limiting strip 6. After the pull-out plate 73 is pulled out, as... Figure 3 As shown, a bowl frame can be placed on it.
[0040] To further explain, the tabletop assembly 5 is connected to the top plate 2 via hinge 52. The hinge 52 is a right-angle self-locking folding hinge, which can unfold the tabletop 51 from the storage state (saving space) that is attached to the side of the top plate 2 to the use state that is horizontal with the top plate 2, and maintain stability through the self-locking function, thereby increasing the operating area.
[0041] To further explain, the space formed between the lunchbox rack 4 and the hot water tank 10 is used to hold the lunchbox. That is, the edge of the lunchbox rests on the top of the lunchbox rack 4 and the top of the top plate 2, while the main body of the lunchbox extends into the hot water tank 10. This allows the heat from the hot water in the hot water tank 10 to be transferred to the lunchbox above through the water, maintaining the temperature through heat conduction, keeping the food warm and preventing it from cooling down quickly.
[0042] To further explain, the two L-shaped strips 71 of the pull-out assembly 7 form a sliding cavity 72, and the pull-out plate 73 can slide along the sliding cavity 72. When unfolded, the pull-out plate 73 is pulled out from the sliding cavity 72. The cooperation between the baffle 75 and the limiting strip 6 (the top of the baffle 75 is higher than the bottom of the limiting strip 6) prevents the pull-out plate 73 from completely detaching. When stored, the pull-out plate 73 slides back into the sliding cavity 72. The baffle 74 can prevent it from sliding in excessively, which is convenient for placing the dish rack without taking up extra space.
[0043] In this embodiment, the height of the food cart is designed to be 60-85cm (top surface of the top panel from the ground), which is suitable for the average height of children aged 3-6 (100-120cm), ensuring that children can operate it with their arms hanging naturally when standing. All exposed parts such as the L-shaped strip 71 of the pull-out assembly 7, the edge of the lunch box rack 4, and the support rod 9 are rounded (radius ≥ 3mm) to eliminate the risk of sharp corner scratches. Anti-accidental brake design: A "rotary safety lock" is added to the brake pedal of the universal wheel 8, which requires a 90° rotation to trigger the brake (operating force ≥ 10N, exceeding the strength of a child's hand), to prevent accidental contact that could cause the food cart to move or lock up.
[0044] It should be noted that this utility model is a multi-functional self-service meal cart for toddlers. In use, the cart is pushed using the handle 3, and then moved to the target position using the four brakeable casters 8 at the bottom of the base plate 1. The casters 8 are then locked to secure the cart. Hot water at 40-50℃ is then added to the hot water tank 10 at the top of the top plate 2 to keep the food warm. Next, the food container is placed on the food container rack 4 within the hot water tank 10, immersing the food container in the hot water. The food temperature is maintained through heat conduction. Then, the tabletop components 5 on both sides of the top plate 2 are unfolded from their folded-down state (fitted against the sides of the top plate 2) to a horizontal position (used with hinges 52). The hinges 52 are self-locking. The function keeps the countertop 51 stable. After unfolding, the bottom groove of the plate can be engaged with the first slide bar 53 of the countertop 51, and the bottom groove of the bowl can be engaged with the second slide bar 54, guiding the plate and bowl to slide smoothly. At the same time, pull the baffle 74 at one end of the pull-out plate 73 in the pull-out assembly 7, so that the pull-out plate 73 slides along the sliding cavity 72 formed by the two L-shaped bars 71 and is pulled out until the baffle 75 contacts the limiting bar 6. At this time, a bowl basket can be placed on the pull-out plate 73. After use, remove the bowl basket from the pull-out plate 73 and push the baffle 74 to make the pull-out plate 73 slide back into the sliding cavity 72. The countertop 51 can then be folded back to the storage state that fits against the side of the top plate 2 using the hinge 52. Compared with the existing multi-functional self-service meal carts for children, this utility model has a reasonable structure, is easy to operate, and can effectively improve the experience and efficiency of children's self-service meal preparation, making it suitable for children's use scenarios.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
