Description
Technical field
The present invention relates to nursing chair, in particular to seat face or ancon can be made with angle appropriate in tilt adjustment
Degree tilts and is easy the chair shifted between chair and bed.
Background technique
In recent years, with the development of China's aging, the user of nursing chair is quicklyd increase.Nursing chair is wanted
Seek multiple functions.Various effort are paid in order to meet the demand, propose a large amount of patent applications every year.
Function to nursing chair most common demands is to be easy the tilt adjustment function of backrest inclination and seated person
The function of being shifted between chair and bed.Seat surface is not set to tilt and only make in general, the tilt adjustment function of the chairs class such as wheelchair exists
The tilt adjustment mode of backrest inclination, and maintain angle between seat surface and backrest and make the angled manner of backrest inclination.
In tilt adjustment mode, the danger that the buttocks with seated person slides forwards in tilt adjustment operation is deposited
The problem of " the back offset " of the surface offsets of the back and backrest that are easy to cause seated person, generation clothes are rolled.On the other hand,
In angled manner, when making backrest inclination as the state for making leg curvature, therefore the burden of knee or waist is increased, and chair
Son is easy to fall backward.Additionally, there are be difficult the problem of tilting (full reclining) completely.
Therefore, in tilt adjustment, while increasing the opening angle of backrest and seat surface, back offset in order to prevent is needed
The function of making seat surface rear portion sink downwards.Itd is proposed kinds of schemes (such as specially about back offset when preventing tilt adjustment in the past
Sharp document 1,2,3 etc.).
Wherein, patent document 1 disclose " while have the function of making back and portions unitary rotation and make back relative to

6 pivot of back frame frame links (the second pivot point of contact).Here, the front-rear direction of the 4th pivot point of contact and lumbar support frame 5
Central point compare rear in a manner of swinging freely with body shell 2 be pivotally connected.Therefore, if making back frame 6 backward
Side topple over, then from Fig. 3, Fig. 6 of patent document 4 as it can be seen that according to centered on the 4th pivot point of contact and front is significantly lifted
Mode tilt, and rear hardly sinks.Therefore occur the back of wheelchair seated person and the surface offsets of backrest " back is inclined
Move ", wheelchair becomes unstable (center of gravity increases or be easy to overturn), and user feels the uneasiness to slide from wheelchair.In citation
It offers in 4, the big several times of backgear ratio front-wheel are the overturnings of the wheelchair as caused by center of gravity height in order to prevent.
Next, needing to make the side of chair and the side of bed to make to be easy by care-giver to shift between bed and chair
It is close to function side by side and one of ancon is removed or be allowed to mobile function in order to avoid ancon obstruction in transfer in face
Energy.The ancon that wheelchair side can be made open is disclosed in citation 4.But handrail disclosed in citation 4 is due to being four
Section structure and be complete parallelogram sturcutre, ancon face must be parallel always with seat surface.Therefore, make backrest rearward under
When drop, it is necessary to bear a part of wrist weight by shoulder.In addition, from Fig. 7 of patent document 4 as it can be seen that ancon from backrest substantially
Degree stretches out, and there are problems that the part of stretching interferes care-giver.
Patent document 5 discloses a kind of nursing chair, and being equipped with a pair at the rear of wheelchair main wheel can rotate
Castor rear-wheel, nursing staff's pushes pedals and float main wheel, enable wheelchair transverse shifting.But it is not needing just
Seat person's voluntarily no setting is required in the case where traveling main wheel, the nursing that four wheels are all made of the castor that can be rotated
Wheelchair or bed are widely used.
As the example for the mechanism for keeping wheelchair ancon mobile in transfer, " ancon down-pressing type wheel is disclosed in patent document 6
The handrail of chair ".The handrail (ancon) includes: ancon pipe, and its rear end rotatably connects with the fulcrum axis of back side frame
It connects, the grooving of defined width is formed in its lower surface length range；Block-like sliding component can exist along the grooving
