Expandable bed

Abstract

The invention relates to a bed which can be retracted in daytime to save effective ground and can be expanded at night for sleeping. The bed consists of a first section, a second section, a third section, a bed board wall, an elongated slot on the board wall, a rivet shaft, a sliding wheel, an inclined rebate lines on the board wall, an inclined rebate lines under the bed board, a low bolt and a high bolt, and is characterized in that: the second section can be pushed into the first section; the third section can be pushed into the second section; the elongated slot on the board wall is formed on the bed board wall; the rivet shaft passes through the elongated slot on the board wall and is riveted with the previous section together; the sliding wheel is arranged below the bed board wall of the second section and the third section; the inclined rebate lines on the board wall are arranged in the bed board wall of the second section and the third section; the inclined rebate lines under the bed board are arranged on two sides of the bed board of the second section and the third section; and the low bolt and the high bolt are arranged on the inclined rebate lines on the bed board. Therefore, the bed is retracted in daytime to only occupy a small area, and is expanded at night to become a big bed for sleeping.

Description

technical field [0001] The invention relates to a bed that can be retracted during the day to save effective ground and can be pulled out at night for sleeping and resting. Background technique [0002] At present, there are many types of beds, such as metal beds, wooden beds, and beds made of composite materials. Their styles are different, but they all have a common shortcoming, and they all occupy a large space. The area occupied by the bed is indeed a big burden, but the utilization rate of the bed during the day is very low, and it can only be fully utilized when sleeping at night. Contents of the invention [0003] In order to overcome the shortage of the existing bed during the day, the present invention provides a retractable bed, the bed shrinks during the day and occupies only a small area, and at night it can be opened to provide a large bed for people to sleep on. [0004] The technical scheme adopted by the present invention to solve the technical problem is:...
