Description

Tray lifting structure and table with same

Technical Field

The present invention relates to a lifting structure, and more particularly, to a lifting structure for a table with a rotatable tray.

Background

According to the Chinese style eating habits, dishes, bowls or other containers are mostly used for holding dishes for the eaters to take food as required. When a large number of eaters meet the eating habit, the dining table with a large table top is needed, and each eater can have a comfortable space to eat. In order to allow eaters sitting at different positions to take dishes conveniently as much as possible, most dishes contained in the tableware are placed in the middle. However, the table top is large, which means that the user sitting around the dining table can hardly take out dishes with long placement distance.

In order to solve the inconvenience caused by the eating habits of the Chinese food, the prior art arranges the rotary tray on the table top, so that an eater only needs to rotate the tray to move dishes far away from the eater to the front of the table, and can take the dishes without getting up.

The existing dining table with the rotary tray can be divided into two structures, wherein one tray is arranged on the table top, the tray structure has the advantages that the tray can be conveniently disassembled and assembled, the table top below the tray is easy to clean, but the tray structure has the defect that the height difference exists between the tray and the table top, when the complete plane table top is needed, the tray needs to be disassembled, and if the tray cannot be or is not easy to disassemble, the using form of the table top can be limited. Another known tray structure is to embed the tray into the table top such that the tray and the table top generally form a common plane. The advantages and disadvantages of this tray structure are contrary to the above-mentioned tray structure, but this tray structure can maintain the smoothness of the table top to increase the convenience of use, but the disadvantage is that there is a gap between this tray and the fixed table top, once there is foreign matter such as soup and soup to fall into the tray from this gap, then the user needs to lift the tray before clearing up. In order to lift the tray, there are structures such as grooves or handles around the tray so that a user can apply force to lift the tray, and if the structure facilitating force application is not provided to maintain the flatness of the tray, the user may need to use a sucking disc or other tools to lift the tray with a certain weight, thereby achieving the purpose of cleaning.

The above-mentioned conventional tray structure cannot provide both convenience of use and convenience of cleaning and maintenance, and how to provide a tray structure that overcomes these problems is an urgent problem to be solved.
