Abstract

The utility model relates to a supporting structure of a bed frame group. A first bed frame, a second bed frame, a third bed frame and an interlocking mechanism are pivoted between a bed frame group, a driving rod is rotated by the press cylinder of the interlocking mechanism, and is pushed to the first bed frame for pivoting, simultaneously, a steel rope is drawn, so as to draw a connecting sleeve rod and an interlocking rod which are nested mutually, and to ensure the pivoting point between the second bed frame and third bed frame to be relatively pivoted. Because the interlocking mechanism is only provided with the press cylinder, the driving rod and the interlocking rod and lifts towards the top surface of the bed frame group because of pivoting, but cannot from buckling towards the bed frame group and the ground, a pace for rod pieces buckling is not required to be reserved between the bed frame group and the ground, and when the supporting structure is used by being matched with the interlocking mechanism which can adjust the height of the bed frame, the height of the bed can be descended to the ground, so as to facilitate the physically-impaired persons to get out of bed.

Description

The supporting construction of bedstead group

Technical field

This utility model relates to a kind of bedstead, particularly relates to a kind ofly having folding rigid frame, and the supporting construction of the bedstead group that can special bracing or strutting arrangement be arranged to the head and the shank of user.

Background technology

The bed that at present generally has specific function, having a kind of is the height that can adjust bedstead, wherein, as TaiWan, China application case number No. 96214439 " height adjustable bed (two) " novel patent case, and as M317216 number " height adjustable bed " novel patent case of TaiWan, China certificate count, the height adjustable bedstead of this kind even bedstead can be reduced to ground proximity is so that handicapped person gets in and out of bed;

Another kind of then be the gradient that to adjust bedstead, as No. 422034 " driving structure improvement of Foldable electric bed " novel patent case of TaiWan, China Announcement Number, or as No. 412974 " the supporting construction improvement of electric foldable bed back bedstead group " novel patent case of TaiWan, China Announcement Number, it can prop up the person's of couching the upper part of the body or lower limb, allow patient or handicapped person be formed a stable sitting posture in bed, it can be read with comfortable posture comparatively, feed or talk with the client, in addition, also can regularly change prone position, avoid adopting identical posture for a long time and make limbs tired.

But the drives structure of above-mentioned adjustable bed gradient design, be to articulate mutually and mutual interlock with a plurality of rod members, and be installed in the bedstead bottom side, mutual drawing by each rod member between driving mechanism, and then lifting or keep flat each bedstead, at this moment, because of can being pivoted relative to each other, each rod member forms an angle, so the articulated section of some rod member can bend projection towards ground, be with, if the driving mechanism of the bedstead of the adjustable tilt degree of above-mentioned prior art is located on the same bedstead with the interlinked mechanism that can adjust the bedstead height, phase is when making this bedstead can have two kinds of functions simultaneously, then can be because of keeping the space of its rod member projection for the driving mechanism of adjusting the bedstead angle of inclination, and make bedstead can't be reduced to ground proximity, cause user can't by bedstead prop up be sitting posture after, leave the bed by lower height again, so the design of adjustable bed gradient of prior art truly has its need for further improvement.
