Abstract

Bed uses X-type lowering or hoisting gear, bed surface two bottom sides are provided with left and right sliding way, both sides are provided with left and right glide path on base, up and down slideway per side is connected by the head of a bed with a set of X-type linkage that cabinet base both ends are set respectively, X-type linkage is mainly made up of the bar of two intersections, two bars are connected by the crosspoint of bar by intersection rotating shaft makes it to rotate around the axis, four end points of two bars, the upper and lower side on side or the right of keeping left is equipped with rotating shaft, it is fixed on same one side of up and down slideway, roller is then housed by the upper and lower side of another side, it can be rolled respectively in the up and down slideway on this side, two sets of X-type linkages support the bed panel of the head of a bed and cabinet base respectively, than whole bed only using a set of X-type linkage and caused cantilever design is improved, add the strength and stiffness of bed.

Description

Bed uses X-type lowering or hoisting gear

Technical field

Bed use X-type lowering or hoisting gear, is related to sick bed, care bed, can lie sofa, or facilitates the equipment of the old,weak,sick and disabled personnel, tool There are the sick bed of special care, and the equipment for motion, body-building or leisure.

Background technology

Sick bed, care bed or the seat that can get up that existing bed surface can be vertically moved up or down, have using X-type linkage, when this When mechanism changes angle, bed surface completes lifting action.But because this mechanism only has upper left (up, down, left, right, before and after, to scheme Direction be defined, similarly hereinafter), totally five pairs of strong points, the left and right end of bed surface are in cantilever for lower-left, upper right, bottom right and intermediate interdigitated point State, its load-bearing property and rigidity are all limited to apart from intermediate interdigitated point farther out.

The content of the invention

The present invention is directed to above-mentioned deficiency, discloses a kind of bed X-type lowering or hoisting gear, and the device makes below the left and right ends of bed surface There is supporter, greatly shorten the jib-length of bed surface, improve the load-bearing property of bed and the rigidity of full bed.

Bed uses X-type lowering or hoisting gear, and the both sides of bed surface bottom are provided with left and right sliding way, and both sides are provided with the base of bed Left and right glide path, it is characterized in that：A set of X-type connecting rod that upper and lower slideway per side is set by the head of a bed and cabinet base both ends respectively Mechanism is connected, the X-type linkage, is mainly made up of the bar of two intersections, the crosspoint of two bars, will by intersection rotating shaft Two bars are connected, its can around intersecting axis of rotation, four end points of two bars, wherein the upper and lower side on keep left side or the right is equipped with rotating shaft, Same one side of upper and lower slideway is fixed on, roller is then housed by the upper and lower side of another side, can be rolled respectively in the up and down slideway on this side Dynamic, two sets of X-type linkages support the bed panel of the head of a bed and cabinet base respectively.

Bed uses X-type lowering or hoisting gear, it is characterized in that：Two sets of X-type linkages of the head of a bed and cabinet base are connected upper and lower Slideway is not at grade.

As seen from the above description, because the head of bed, pin both ends set a set of X-type linkage, the head pin both ends of bed respectively All the time there is fulcrum support, only use a set of X-type linkage than whole bed, cantilevered structure is improved, the intensity of bed Both increased with rigidity.

Brief description of the drawings

Fig. 1 is the schematic diagram of one embodiment of the invention.

Fig. 2 is upper and lower slideway not in the schematic diagram of conplane embodiment.

Embodiment

In Fig. 1, the bars 3 of two intersections are connected with bar 5 by intersection rotating shaft 4, and the left end of bar 3 is upper, equipped with rotating shaft 1 and fixed On sliding way 9, the right-hand member of bar 3 can roll under equipped with roller 8 in glide path 10, and the left end of bar 5 is under, equipped with rotating shaft 2 And be fixed on glide path 10, the right-hand member of bar 5 can roll equipped with roller 6 in sliding way 9 upper；Figure right side and said structure It is identical, but in the opposite direction, when lifting body 7 jacks sliding way 9 upwards, two sets of left and right X-type linkage ensure that Sliding way 9 remains parallel with glide path 10, shown in dotted line.

Fig. 2 is identical with Fig. 1 principles, but the upper and lower slideway that left and right two width X-type linkage uses respectively is not same flat On face.

Claims

1. bed with X-type lowering or hoisting gear, the both sides of bed surface bottom are provided with left and right sliding way, on the base of bed both sides be provided with it is left, Bottom right slideway, it is characterized in that：A set of X-type connecting rod machine that upper and lower slideway per side is set by the head of a bed and cabinet base both ends respectively Structure is connected, the X-type linkage, is mainly made up of the bars of two intersections, the crosspoint of two bars, by intersection rotating shaft by two Bar is connected, its can around intersecting axis of rotation, four end points of two bars, wherein the upper and lower end on keep left side or the right is equipped with rotating shaft, Gu Same one side of upper and lower slideway is scheduled on, roller is then housed by the upper and lower end of another side, can be rolled respectively in the upper and lower slideway on this side Dynamic, two sets of X-type linkages support the bed panel of the head of a bed and cabinet base respectively.

2. bed according to claim 1 X-type lowering or hoisting gear, it is characterized in that：Two sets of X-type connecting rods of the head of a bed and cabinet base The upper and lower slideway that mechanism is connected is not at grade.
