Description

The adjustable length combination cot

Technical field

The utility model belongs to the furniture product, relates generally to a kind of bed accessory.

Background technology

At present, no matter be that to use double doss in single sick bed in the hospital ward or the family room all are rigid structures, promptly can not regulate the width size of its bed surface.In actual use, when the long-term hospitalization of patient need be accompanied and attended to the nursing staff, entourage in night rest berth not, very tired, rent folding bed temporarily, not only need payment or rent, and use also inconvenient; Double bed is placed in the less room of floor space, occupies than the big room area, has reduced the activity space of people on daytime in the room, seems very crowded.

Summary of the invention

The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, and design provides a kind of adjustable length combination cot, reaches the convenient purpose of using.

Basic design of the present utility model is, installs the flute profile slideway in correspondence below main bed frame frame two end floor beams or below two side girders; The gusset piece that plug-in mounting alignment pin fits on the secondary bed frame one side head admittedly, on the upper and lower end face of gusset piece, limited roller and seat board are installed respectively, equipped from the inside to the outside baffle plate and support roller on the seat board lower plane, support roller is positioned at the limited roller outside left in vertical direction, secondary bed frame is inserted on the flute profile slideway, and limited roller contacts with the upper and lower orbital plane of flute profile slideway respectively with support roller; Install and fix roller in the flute profile slideway of a relative end with support roller, this fixed idler whell is positioned at secondary bed frame below, and is in contact with it cooperation; Install spring base on main footpost, compression spring and top board are configured in the spring base, and compression spring upper/lower terminal face contacts with the spring base bottom with the top board lower surface respectively, and top board is positioned at the fixed idler whell inboard, on the top board upper surface leans below secondary bed frame; Secondary bed supporting leg is installed on the outer lower portion of secondary bed frame, is so far constituted the adjustable length combination cot.

The utility model structural design is new reasonable, regulates the operation simple and convenient, and secondary bed frame draws that to push row laborsaving flexibly.This bed can be the entourage rest berth well is provided when using in hospital ward; Can reduce the berth floor space on daytime when in family room, using, guarantee activity space.
