Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seats, in particular to a seat with a chassis device. Background Art
[0002] High-legged dining bar chairs are usually used in places such as pubs and cafes for people to dine and communicate. High-legged dining bar chairs are seats used with bar counters. They are also used at the company's front desk or bar front desk. Generally, high-legged dining bar chairs can be adjusted in height by the lifting handle under the seat.
[0003] According to a publicly disclosed bar chair with high comfort level (Announcement No.: CN212995484U), the position of the gas spring is designed in the above application. When a person sits on the seat plate, the outer rod is forced to move up and down on the inner rod, thereby compressing the gas spring. Through the buffering support of the gas spring, the downward pressure exerted by the human body on the seat plate can be absorbed, which can enhance the vibration reduction effect of the device.
[0004] However, in actual use, the above-mentioned device is provided with a gas spring so that when the human body applies pressure to the seat plate, the pressure can be absorbed to achieve a vibration reduction effect. However, when the bar chair is in use, the chassis is in contact with the ground, and the environment in which the bar chair is located will inevitably have some garbage on the ground. When the operator moves the bar chair, if he does not pay attention to the ground environment, the chassis will be covered with garbage. The presence of garbage over a certain area will cause the foot pad on the chassis to reduce its contact with the ground, thereby reducing the stability of the seat body. In view of this, we propose a seat with a chassis device. Utility Model Content
