Electric bed having no bed board and being covered in material

Abstract

An electric bed having no bed board and being covered with a surface material includes: a foldable bedframe jointed through connectors and connected with bed legs, overturningly foldable frames disposed on the bedframe, a drive device disposed on the bedframe (1), a surface material covered directly onto a plurality of frames, and a tensioning mechanism for tensioning the surface material at a surface of the frames; the tensioning mechanism includes embedded strips and pipes, and may further include a clamp fastener; when the surface material is in a tensioned state, an embedded strip connected at one end of the surface material is limited within a limiting slot of a pipe at one side, and another embedded strip connected at another end of the surface material is limited within a limiting slot of another pipe at the opposite side.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to an electric bed, in particular to an electric bed having no bed board and being covered with a surface material.BACKGROUND OF THE INVENTION[0002]Traditional electric beds have the following forms. One is a structure that a bed board thereof is customized in size, and such structure requires the bed board, hinges, a mattress, and other materials to be collectively comprised therein, such that technical process and material costs are relatively high. Another one is a steel mesh structure, an appearance of which is not admirable as no material is covered thereon for a good look. In addition to these, there is also a structure that steel mesh thereof is additionally equipped with a covering, but an appearance thereof still cannot be guaranteed due to particularly complicated technical process of the structure.[0003]Although the existing electric beds have a high degree of automation that an angle of the bed can be willfully a...

AI Technical Summary

Benefits of technology

[0032]5) A support connecting rod is directly welded by using a sheet metal, which not only reduces installation parts, but also improves the strength of the frame;

[0033]6) A step screw, a plastic sleeve, and a plastic gasket are fitly used at a connection between the frames as well as at a rotatable joint such that a movement clearance is retained and no rotation noise is generated; and the rotatable joint is designed near a welding point of the frame to increase the strength.

Problems solved by technology

One is a structure that a bed board thereof is customized in size, and such structure requires the bed board, hinges, a mattress, and other materials to be collectively comprised therein, such that technical process and material costs are relatively high.

Another one is a steel mesh structure, an appearance of which is not admirable as no material is covered thereon for a good look.

In addition to these, there is also a structure that steel mesh thereof is additionally equipped with a covering, but an appearance thereof still cannot be guaranteed due to particularly complicated technical process of the structure.

Although the existing electric beds have a high degree of automation that an angle of the bed can be willfully adjusted according to one's wish to achieve a more comfortable resting posture, there are still the following problems: 1) the bed board requires to be pre-manufactured and has a high requirement on strength such that the manufacturing cost is relatively high; 2) lying experience is unpleasant, and thus a soft mattress is needed to be placed on the wooden bed board, which, however, is not convenient for folding and accommodation of the electric bed, such as a Chinese patent No. 201611021896.7 that discloses an electric folding bed and electric folding sofa-bed, in which a mattress is placed on a bed board of the folding bed and a latex mattress or a memory foam mattress is used as the mattress; and placement of the mattress requires additional mattress fixing means, such as a Chinese patent No. 201420384833.8 that discloses a mattress fixing device which is arranged at the tail of a bedframe to limit the longitudinal displacement of the mattress.
