Abstract

An electric bed includes a frame, an actuator, a base body and a plate member. The frame includes a fixed rack and a movable rack movably disposed at the fixed rack. The actuator is disposed between the fixed rack and the movable rack in a way that the movable rack is movable relative to the fixed rack. The base body is disposed at a top side of the frame. The plate member is movable into and out of the base body. As a result, the plate member can be used as a table or a supporting frame for replacing things thereon, and the plate member can move back when user do not want to use the plate member.

Claims

1. An electric bed, comprising:

a frame, comprising a fixed rack and a movable rack movably disposed at the fixed rack;

an actuator, disposed between the fixed rack and the movable rack in a way that the movable rack is movable relative to the fixed rack;

a base body, disposed at a top side of the frame and provided with a top plate and two side plates extending downwardly from two sides of the top plate, respectively; and

a plate member, movable into and out of the base body;

wherein the top plate of the base body, the two side plates of the base body and the frame form an accommodating space for accommodating the plate member;

the accommodating space has an opening, through which the plate member is movable into or out of the accommodating space.

2. The electric bed as claimed in claim 1, wherein the base body comprises two bottom plates disposed at the frame and extending oppositely from bottom ends of the two side plates, respectively.

3. The electric bed as claimed in claim 2, wherein the base body has a limiting portion extending downwardly from the top plate;

the plate member comprises an elongated slot extending along an imaginary line;

the limiting portion extends through the elongated slot, so that the plate member is movable relative to the base body along the imaginary line.

4. The electric bed as claimed in claim 2, wherein the base body further comprises a blocking plate extending downwardly from a side of the top plate opposite to the opening.

5. The electric bed as claimed in claim 1, wherein the plate member comprises a bottom portion and a protruded fringe extending upwardly from a periphery of the bottom portion.

6. The electric bed as claimed in claim 1, wherein the fixed rack comprises a rack body and a first supporting board disposed at a top side of the rack body, and the base body is disposed at a top side of the first supporting board of the fixed rack.

7. The electric bed as claimed in claim 6, wherein the first supporting board has a hollow portion for disposing the base body therein.

8. The electric bed as claimed in claim 6, wherein the fixed rack further comprises a first cushion disposed at the top side of the first supporting board, the first cushion has a notch, in which the base body is located.

9. The electric bed as claimed in claim 8, wherein a top of the base body is flush with a top of the first cushion.
