The device sets up the pivot and is connected between seat and shank board, between shank board and the sole, the back of sole is fixed with the tip and has semi -girder under the sole of sole pivot, and the back of seat is fixed with the tip and has semi -girder under the seat of seat pivot, is linked to each other sole pivot and seat pivot by the vaulting pole, or links to each other the shank board pivot of sole pivot with shank backboard face, makes sole and shank board remain throughout point -blank.

Description

A kind of sole device of chair bed

Technical field

A sole device for chair bed, relates to bed, chair, sofa or facilitates patient's equipment, and it is special particularly to haveThe sick bed of nursing and the chair that is applicable to weakling, and be the equipment of motion, body-building or leisure.

Background technology

(ZL200620098315.5) described curved surface chair bed of Chinese patent " a kind of freely-supported support curved surface chair bed ",Its panel is made up of three of upper, middle and lower, corresponds respectively to upper body, thigh and the shank of human body, when user existsWhile sitting up on it, foot is unsettled, does not rely on, and comfortableness and convenience are all not ideal enough.

Summary of the invention

The utility model does not arrange the deficiency of sole for above-mentioned patent, disclose a kind of sole device of chair bed, whenWhen user sits up, this device makes sole and calf plate angulation, and is basically parallel to seat or ground, usesPerson's foot is by sole support, comfortable, reliable, and this apparatus structure is simple, and cost is low, and has larger bearing capacity;In the time not needing, sole and calf plate still keep point-blank.

The sole device of a kind of chair bed described in the utility model, is characterized in that: bed panel is by backboard (11), seat(10), the most of composition of calf plate (5) and sole (1) four, between seat (10) and calf plate (5) by sittingLeg rotating shaft (7) is connected to each other, between calf plate (5) and sole (1), is connected to each other by legs and feet rotating shaft (3),The back side of sole (1) is fixed with semi-girder under sole (2), and there is sole rotating shaft (4) its end, seat (10)The back side is fixed with semi-girder under seat (8), and there is seat rotating shaft (9) its end, and itself and sole rotating shaft (4) are by strut(6) be connected.

The sole device of described a kind of chair bed, is characterized in that: described strut (6) can be square with seat rotating shaft (9)Just disassemble, and then be connected with the calf plate rotating shaft (12) at calf plate (5) back side.

As shown from the above technical solution, the sole device of a kind of chair bed described in the utility model, semi-girder under its sole,Under strut, seat, semi-girder is connected by rotating shaft with calf plate, forms quadric chain. When calf plate moves at chair bedWhile rotating in work, because seat rotating shaft is connected with sole rotating shaft by strut, make sole and seat energy basicKeeping parallelism, reaches user and keeps flat double-legged effect. Quadric chain is simple, and holding capacity is stronger.

When described strut disassembles with one end that seat rotating shaft is connected, and then while being connected with calf plate rotating shaft,When no matter what action calf plate do in the action of chair bed, sole and calf plate remain point-blank, applicableDo not need or do not allow to do the occasion of relative motion in foot, calf.

Brief description of the drawings

Fig. 1 is the side view of a kind of sole device embodiment of chair bed.

Fig. 2 is the sitting posture side view of embodiment described in Fig. 1.

Fig. 3 is the side view of a kind of another embodiment of sole device of chair bed.

Fig. 4 is the sitting posture side view of embodiment described in Fig. 3.

Concrete embodiment

In Fig. 1, bed panel in prone position state, wherein, sole 1 with calf plate 5 by legs and feet rotating shaft 3 phasesConnect, calf plate 5 is connected by sitting leg rotating shaft 7 with seat 10, and the back side of sole 1 is fixed with semi-girder 2 under sole,There is sole rotating shaft 4 its end, and the back side of seat 10 is fixed with semi-girder 8 under seat, and there is seat rotating shaft 9 its end,It is connected by strut 6 with sole rotating shaft 4. In figure, dotted line is depicted as the side view while changing into sitting posture.

In Fig. 2, the panel of bed is in sitting posture state, and now calf plate 5 is sagging, and legs and feet rotating shaft 3 drives sole1 action downwards, the strut 6 that sole rotating shaft 4 is connected with seat rotating shaft 9 by the other end withstands, thereby sole 1 is protectedHold and the approximately parallel position of seat 10, be convenient to place both feet.

In Fig. 3, one end of strut 6 and seat rotating shaft 9 disassemble, then with fixing little in calf plate 5 back sidesLeg plate rotating shaft 12 is connected, and itself and sole rotating shaft 4, legs and feet rotating shaft 3 form leg-of-mutton three summits, based on threeThe stability of dihedral, no matter calf plate 5 is in level or when sagging, and sole 1 remains at calf plate 5On straight line.

In Fig. 4, calf plate 5 is sagging in the time of sitting posture, and one end of strut 6 is connected with calf plate rotating shaft 12, sole1 still keeps point-blank with calf plate 5.
