[0017] Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings.

[0018] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art.

[0019] Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted.

[0020] First, the configuration of a mobile food tray delivery cart according to one embodiment of the present invention is as follows through FIGS. 1 to 10.

[0021] The food tray delivery cart in the present embodiment comprises a cart body (10) having an open structure with an open front side to allow the food tray (100) to be inserted, a handle part (20) provided on the upper side of the cart body (10), a moving wheel (30) provided on the lower side of the cart body (10), a bottom plate (40) configured at the bottom of the cart body (10) for the food tray to be placed on, and an opening / closing door (50) rotatably provided at the open part of the cart body (10) to prevent the food tray from falling out.

[0022] At this time, the floor plate (40) has a structure that allows rotation by means of a hinge pin (41) in the center, with an inclined portion (40a) formed along the periphery edge, and a rotating bracket (43) is formed on both sides of the cart body (10), with a guide groove (42) of a certain length formed to guide the hinge pin (41) during the rotation process of the floor plate (40), and the cart body (10) is equipped with a floor plate support frame (13) for supporting the floor plate (40), as can be seen through FIGS. 2 and 3. In this embodiment, it is preferable that the surface of the floor plate (40) has a stainless steel finish structure.

[0023] In addition, as can be seen in FIGS. 6 and 7, a guide ring (51) is provided on one side of the opening / closing door (50) so as to be rotatably fitted into a support column (11) of the cart body (10), and a fitting groove (52) is formed in the guide ring (51), and a fitting projection (12) is provided protruding from the support column (11) corresponding thereto.

[0024] Meanwhile, the cart body (10) is provided with a printing unit (14) for checking the quantity of food trays loaded as shown in FIG. 8, and it is preferable that a cover body (60) made of non-woven fabric is placed on the outside of the cart body (10) as shown in FIG. 10 to prevent foreign substances from entering during the delivery process.

[0025] Unexplained reference numeral 15 in the drawing represents the upper frame forming the upper part of the cart body.

[0026] We will now examine the effects of using the mobile food tray delivery cart of the present invention, which has such a configuration.

[0027] The food tray delivery cart of the present invention allows food trays (100) continuously discharged from a food tray washing machine to be placed in predetermined quantity units.

[0028] That is, the food trays (100) discharged with the front open are sequentially placed on the bottom plate (40) in a stacked form by opening the opening / closing door (50) and, when they are stacked to a certain height, the number of food trays (in units of about 100) is checked through the scale marked on the printing part (14) and then the opening / closing door (50) is closed.

[0029] At this time, the opening / closing door (50) can be fixed in a closed state by the fitting projection (12) provided on the support column (11) of the cart body (10). When the opening / closing door (50) is to be opened again, if the opening / closing door (50) is slightly lifted, the fitting groove (52) formed in the guide ring (51) is detached from the fitting projection (12) as shown in FIG. 6, and it can be confirmed that a state in which rotational opening / closing is possible is achieved.

[0030] In this way, when the opening / closing door (50) is closed to prevent the food tray (100) from coming off during the delivery process, the food tray (100) can be protected from the ingress of foreign substances such as dust by covering it with a cover body (60) as shown in FIG. 10, and delivery work using a vehicle can be carried out.

[0031] In addition, since an inclined portion (40a) is formed on the bottom plate (40), it is possible to prevent food falling from the tray from flowing out during the recovery process.

[0032] Meanwhile, when storing the cart, the bottom plate (40) is rotated upward, and storage is performed in a form where the carts overlap each other as shown in Fig. 4, thereby providing the advantage of minimizing storage space.

[0033] Therefore, the food tray delivery cart of the present invention enables safe and efficient delivery of a large volume of food trays without using a separate packaging box for delivery, thereby preventing worker injury and allowing delivery operations to be carried out at a low cost.

[0035] Meanwhile, FIGS. 11 and 12 show a configuration according to another embodiment of the present invention, wherein a pressure plate (70) is additionally configured on the upper part of the cart body (10) to prevent movement of the loaded food tray, and the pressure plate (70) is connected to the upper frame (15) of the cart body (10).

[0036] At this time, it is preferable that the upper frame (15) be formed with a circular cross-sectional structure so that the height of the upper frame (15) can be adjusted according to rotation.

[0037] Additionally, the above-mentioned pressure member (70) has a structure in which an elastic member (72) is connected to the lower side of one side of a pressure member body (71) that forms a "ㄱ" shape by an elastic spring (73) to provide elastic support, and a cushioning ball (74) made of silicone material is configured at the lower end of the elastic member (72) to prevent damage caused by contact with the food plate (100).

[0038] Meanwhile, a damage prevention layer (75) for preventing surface damage is formed as a coating on the surface of the buffer ball (74), and the damage prevention layer (75) preferably has a mixed composition in the ratio of 10-30% by weight of polyethylene glycol, 1-10% by weight of cetyltrimethylammonium bromide, 5-10% by weight of polycaprolactone, 1-10% by weight of carbon fiber, 10-20% by weight of sodium propionate, 5-20% by weight of tricresyl phosphate, 1-10% by weight of DGME (Diethylene Glycol Monophenyl Ether), 5-10% by weight of ascorbic acid, and 1-15% by weight of silicon fluoride.

[0039] With this configuration, the upper part of the food tray (100) loaded at a certain height on the cart body (10) can be pressed using the height-adjustable pressure plate (70), thereby preventing shaking and impact during the movement process and allowing the food tray delivery operation to be carried out more safely.

[0040] In particular, the pressure band (70) has a structure in which the pressure band body (71) and the elastic band (72) are connected by an elastic spring (73), and a cushioning ball (74) is formed, thereby providing the advantage of shock absorption and preventing damage to the contact surface of the food plate (100).

[0041] In addition, a damage prevention layer (75) is formed as a thin film coating on the surface of the cushioning ball (74), thereby providing the advantage of preventing the silicone cushioning ball (74) from being deformed or damaged.

[0042] At this time, the damage prevention layer (75) in this embodiment has improved surface lubricity because it is a mixture of polyethylene glycol and cetyltrimethylammonium bromide, polycaprolactone performs the function of improving coating adhesion, carbon fiber and sodium propionate perform the function of preventing cracks by strengthening the durability of the damage prevention layer (75), and tricresyl phosphate performs the function of suppressing bubble generation during the coating process. In addition, the additionally added DGME strengthens the bonding strength between the mixtures to strengthen the coating density, and ascorbic acid and sodium silicon fluoride exhibit the effect of preventing oxidation and discoloration of the damage prevention layer (75).

[0044] Furthermore, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the food tray delivery cart structure of the present invention can be implemented with various modifications by those skilled in the art.

[0045] For example, in the above embodiment, the opening and closing door is described and illustrated as being provided only on one side of the opening of the cart, but if necessary, the opening and closing door can be installed symmetrically on both sides.

[0046] Therefore, such modified embodiments should not be understood separately from the technical spirit or scope of the present invention, and such modified embodiments should be considered to be included within the appended claims of the present invention. Explanation of the symbols
