Description

Healthy deck chair

The utility model relates to a kind of chaise longue or easy chair that independent adjustable support parts are arranged, particularly a kind of Healthy deck chair.

A kind of Healthy deck chair of the prior art as shown in Figure 1, foot rest 4, underframe 5 is formed holder with oblique frame 6 affixed one, after-poppet 7, backrest 2, seat 1 and holder are formed a four-bar linkage, the joint portion of backrest 2 and seat 1 can be gone up very and recessed balleting, thereby the people who couches on backrest 2 and seat 1 can be stretched accordingly, bend motion with the exercise waist, when not moving, but forward swing locating rack 31, its sidepiece ring and clasp 61 are pegged graft, to reach the purpose of the constraint four-bar linkage free degree,, uses this Healthy deck chair so that can be used as general chaise longue.Because control stick 8 peripheral obstacles that are fixed in locating rack 31 rear sides are more, passing that control stick 8 positions and when changing the location height, finger is very easily crushed by member on every side; Again because when balleting, by carrying out the upper and lower dislocation campaign of similar " shearing " all the time between frame 2 and seat 1 outer rim and the oblique frame 6, and just be the sagging naturally place of lying posture human body palm, so when using, this " shearing " phenomenon often causes the tong even the incident of cutting off the hands herein.Simultaneously, on draw locating rack 31 so that it can the contract extension spring of ensconcing backrest 2 rear portions also may jam a finger and eject and produce danger, and for a long time with loose extension spring owing to fail fully to strain locating rack 31, and when causing recessed stroke in balleting, locating rack 31 is got rid of play bullet and takes place to block with ground bumps accident.

The purpose of this utility model is to overcome weak point of the prior art, and provides a kind of safe in utilization, simultaneously the better simply again Healthy deck chair of structure.

The purpose of this utility model is to realize by following approach.

Healthy deck chair, the positioner that comprises holder, forms after-poppet, backrest and the seat of four-bar linkage with holder and can retrain the said four-bar linkage free degree when needing, have locating rack and buckle pieces in the positioner, the locating rack bottom is hinged with holder, and its top connects with seat by buckle pieces.

In the time need not retraining the free degree of said four-bar linkage, locating rack no longer is connected with backrest or seat like this, but connects with holder.Thereby omitted necessary extension spring in the routine techniques, and the oblique frame in the holder is able to freely design (as shortening oblique frame length owing to the direct support member that is not re-used as locating rack, the interface that makes itself and underframe is as far as possible near foot rest) to avoid " shearings " of the prior art phenomenon, buckle pieces operating barrier on every side greatly reduces simultaneously.

The purpose of this utility model can also realize by following approach.

Buckle pieces by distribute along the axially spaced-apart of the bearing bar in the locating rack and be fixed in the bearing bar rear lateral portion numerous grooves and or be fixed on the seat outer rim or the short strut that is fixed on the hinge lateral surface of hinged seat and backrest is formed, wherein each groove downside front end all has limited step.

Buckle pieces by the front and back through hole that distributes along the axially spaced-apart of the bearing bar in the locating rack and or affixed or forms with the seat outer rim with affixed " L " shape shank of the hinge of hinged seat and backrest, wherein the shank front end has the limited step of dashing forward down.

Oblique frame length in the holder preferably is at most on the seat seat and backrest pin joint to 5/6 of length between seat and the foot rest pin joint.

In sum, the utility model has following advantage compared to existing technology: simplified product structure, and safety in utilization is again to improve, easy to operate, safety has been stopped existing " shearing " phenomenon that jams a finger in the prior art.
