Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cart mounting structure in a catering cart used for providing meals in hospitals, nursing homes, and the like.

2. Description of the Related Art In hospitals and the like, when meals are served, catering carts are used that store trays in multiple stages on which tableware on which foods such as staple foods, main dishes, side dishes, and soups are placed.

More specifically, in a cooking and heating room in a hospital or the like, tableware filled with the food is placed on a tray based on a predetermined menu, and the trays are sequentially placed in the food delivery car, and the food delivery car is placed in the hospital or the like. The trays on which the foods are placed are taken out from the food service carts and served to the rooms by traveling through the corridors. necessary.

However, a large catering cart is difficult to move in a hospital or the like, and there is a problem that it takes time and labor to go around all the rooms.

Therefore, in order to deal with such problems, the food service cart is divided into a main body and a cart, and the heavy food service car body equipped with heating and cooling equipment for refrigerating and heating the food is not moved. There is also known a serving cart which is stationary without any trays and moves only the cart in which the trays are accommodated in multiple stages during serving.

The food service cart consisting of the cart and the food service car main body has a first wheel part, an insert cart capable of holding a tray inside, and a second wheel part, and stores the insert cart inside. When the insert cart is stored in the storage space, the transport vehicle body supports the insert cart and moves the first wheel A food transport vehicle is known which is provided with a placement section for separating the section from the running surface of the second wheel section.

In the case of the catering cart divided into the catering cart main body and the cart as described above, only the cart needs to be moved when serving meals, so operability is improved compared to the case of moving the entire catering cart. However, the structure is complicated when the cart is connected to and stored in the food service car body, and it is necessary to operate the cart accurately to integrate the cart with the food service car body. However, there is a problem that failures and malfunctions are likely to occur due to repeated use during lunch and dinner.

In addition, in the case of a food service cart that cools and heats the food in the cart by bringing the cart into contact with the front of the cart body, the cart itself is in direct contact with the outside air, so the cart itself must have sufficient heat insulation. For this reason, it is necessary to increase the thickness of the walls constituting the cart, resulting in an increase in the weight of the cart itself, which has the drawback of deteriorating the operability of the cart.

In addition, the insert cart can be stored in the transport vehicle main body, and an insert cart mounting portion is provided in the storage space so that the first wheel portion of the insert cart can be moved from the running surface of the second wheel portion of the transport vehicle main body. In the case of food transport vehicles that are spaced apart, although the running performance of the food transport vehicles is improved, considerable labor is required to run the insert cart onto the placement portion of the transport vehicle body, so the serving work is required. There was a problem that it was a heavy burden for mainly female staff who carried out the work.

An object of the present invention is to provide a cart mounting structure in a catering trolley, which is composed of a trolley main body and a cart, and which secures operability and heat insulation of the cart and enables serving with excellent mobility. to do.

According to the first aspect of the present invention, there is provided a tray storage chamber for storing trays in multiple stages, a cart movable by casters attached to the bottom, and a cart storage chamber for storing the carts. In the food service car having a food service car body, a pair of left and right engaging recesses extending in the front-rear direction is provided on the outer bottom surface of the food service car body, and the cart is accommodated in the tray of the service car body below the tray accommodation chamber of the cart. A catering cart having an engaging arm that is inserted into the engaging recess when it is housed in a chamber, and a lifting means that lifts the cart when the engaging arm and the engaging recess are engaged. Cart mounting structure.

According to a second aspect of the present invention, in the cart mounting structure of the first aspect of the present invention, the lifting means comprises an upwardly sloping portion formed in an opening portion of the engagement recess of the food service trolley body, and the upwardly sloping portion. It is a horizontal part extending from the top of the part to the deepest part of the engaging recess, and by inserting the engaging arm of the cart into the engaging recess, the cart rises along the inclined part of the engaging recess In addition, it is characterized in that an engaging arm enters and engages with the engaging concave portion so that the food delivery vehicle main body and the cart are integrated.

According to the third aspect of the present invention, in the cart mounting structure of the second aspect of the present invention, the engaging arm is attached to either the ascending inclined portion of the lifting means in the food serving truck body or the tip portion of the engaging arm of the cart. It is characterized in that an introductory rotator is provided for inducing the insertion of the.

According to the cart mounting structure for the catering cart according to the present invention, the engaging arm provided below the tray accommodating chamber of the cart in the engaging recess provided at a position close to the floor surface, that is, the outer bottom of the catering cart body. Only by inserting the cart, the cart is mounted integrally with the catering cart body, and the engaging arm is inserted at a position close to the floor surface, so even a female staff member can easily mount the cart. It has the practical advantage of being easy to do.

Further, according to the present invention, since the above-described cart mounting structure is incorporated in the outer bottom surface of the food service trolley body, there is an advantage that the design of the cart storage chamber itself of the food service trolley body does not need to be changed.
