Description

Manual zero-g chair

Technical field

The utility model relates to a kind of chair more particularly to a kind of manual zero-g chairs.

Background technique

The human body most of the time all in cardiac position be higher than foot normal gravity effect state, whether sitting posture, stand Appearance, the effect that blood circulation is influenced by gravity under the state are all similar.Currently, mostly using massage armchair by the backrest of massage armchair It is set as adjustable state with cushion, so that can realize that foot position is higher than heart while keeping Human Physiology bending Position, the case where making the blood circulation effect under the influence of human body normal gravity be changed into similar agravic/anti-gravity, to obtain Different massage effect, experiment show there is visibly different experience under this zero-g/anti-gravity effect, can obtain It is good to loosen and comfortably experience.

Zero-g massage chair is that zero-g principle and vibration massage function technology are combined together and are designed, the people of massage armchair Body ergonomic designs and zero-g technology can make one in the raw, to resist discomfort brought by terrestrial gravitation, the weight of human body The heart is placed on bung fat, other physical feelings by pressure, are not massaged under such state, can relieve pressure, discharges tired Labor, no matter body or spirit can all be felt more easily, therefore massage effect is particularly effective.Existing zero-g massage chair is mainly deposited The shortcomings that be: overturning before and after arm rest can be made generally by driving device when in use and enable on double-legged bracket Lower rotation then at least needs two sets of driving devices, and often structure setting is complicated, causes chair body volume larger, higher cost, It is cumbersome, benefit inconvenient for use.

Summary of the invention

The technical issues of the utility model solves is to overcome the deficiencies of existing technologies, and is provided a kind of by turning manually tiltedly It leans on lock and hand control switch is able to achieve the manual zero-g chair for the rotation for freely controlling after-frame and side arm.

In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals:

Manual zero-g chair, including mounting, the fixed seat cushion being located on mounting, mounting includes being placed on ground Left arm rest and right arm rest, the V-arrangement cantilever being separately fixed on left arm rest and right arm rest are fixedly connected on a left side with screw bolt and nut and lean on It is supporting beam between arm and right arm rest, the fixed middle frame being located on the horizontal arm of supporting beam and V-arrangement cantilever, rotatable hinged Side arm on front side of middle frame, the after-frame being locked on the oblique arm of V-arrangement cantilever with nuts and bolt, end can be screwed out by screw thread Or what is screwed in passes through left arm rest and right arm rest and fixes the lock of swaying being located on V-arrangement cantilever respectively, is hinged in side arm back side edge Between and drive side arm using side arm back side edge as pivot center make rotate upwardly and downwardly cylinder, be fixedly connected among middle frame back side edge And piston rod, the fixed switch being located on middle frame and control cylinder starting or close that fixing sleeve is set in cylinder, pass through control Switch control cylinder starting processed is closed, and cylinder is moved forward or moved backward along piston rod, thus before cylinder drive side arm Frame back side edge is that pivot center is rotated up or rotates down；It is swayed by two unscrewed on left arm rest and right arm rest respectively Lock, V-arrangement cantilever is unlocked, so that after-frame is posteriorly or anteriorly rotated with the pivot center of oblique arm on V-arrangement cantilever；By tightening respectively Two on left arm rest and right arm rest locks of swaying, to V-arrangement cantilever be locked, while after-frame stopping acts；Wherein, after middle frame Deck is fixed among side, deck is equipped with card slot, and piston rod rear end fixing sleeve is set in card slot；Seat cushion is by for branch The front foot pad for supportting human body both feet, the middle pad for being used to support human buttock, the rear back mat composition for being used to support human body back, front foot Pad, middle pad, rear back mat are successively linked together to form integrated elastic seat cushion from front to back, front foot pad, middle pad, rear back mat point Side arm, middle frame Gu Ding be located at, on after-frame.

When original state, side arm and horizontally disposed middle frame are in 90 degree of angles, double-legged when facilitating human body sitting posture state It can step on side arm；When user needs to lie down, by unscrew manually lock of swaying make after-frame with V-arrangement cantilever axis forward or to After rotate, slightly firmly after-frame can be pressed backward so that after-frame is overturned to the back lower place to the state of lying down, then tighten sway lock will after Frame is locked at again on left arm rest and right arm rest；Start cylinder further through hand control switch, cylinder is under the cooperation of piston rod Side arm is driven to be rotated up parallel with middle frame to side arm, at this point, after-frame lies low in lying status for human body backrest.When need again Again sit up sitting posture when, then respectively by turn manually sway lock and manually actuated button switch side arm and after-frame are restored to first Beginning position.Using the composite structure for being arranged seat cushion fixed outside mounting, respectively by turning sway lock and hand manually Dynamic control switch, realizes the rotation that can freely control side arm and after-frame, enables a user in sitting posture and lie down as needed Free switching between posture, substantially increases ease of use and operating flexibility.

Preferably, the horizontal arm of the V-arrangement cantilever is divided middle frame two sides by the combination fasteners of screw bolt and nut It is not fixedly connected on left arm rest and right arm rest.Wherein, horizontal arm and oblique arm and the integrated V-arrangement cantilever of sunpender group；It is logical The V-arrangement cantilever being arranged in mounting is crossed, improves the mounting formed by left arm rest, right arm rest, side arm, middle frame, after-frame permanent Fixing and stationarity in use process, and make the operations such as installation, disassembly, maintenance more convenient.

Preferably, middle frame and after-frame are fixed with waveform reinforcing rib or S-shaped spring, centre is further improved The enabling capabilities of frame and after-frame ensure that the safety that user is sitting in or is lain in mounting.

Preferably, left arm rest bottom and right arm rest bottom are equipped with antiskid groove, avoid user and be sitting in or lie in Left arm rest and right arm rest occur sliding or even topple over when mounting.

Preferably, being enclosed with tremolo inside the seat cushion and rear back mat, it is sitting in or lies in for user Vibration massaging function is provided on middle pad and rear back mat.

Preferably, being equipped with the winding cloth for including Electrothermic wire inside the rear back mat, fever function is provided for rear back mat Energy.

Preferably, being fixed with pillow at the top of the rear back mat, the setting of pillow is so that user is sitting in or lies in Head can more comfortably lean against on pillow when on seat cushion.

Preferably, the switch is that button switch or pull ring switch.

The utility model has significant technical effect: using fixed outside mounting due to using above technical scheme It is arranged the composite structure of seat cushion, respectively by turning sway lock and hand control switch manually, realizing freely to be controlled The rotation of side arm and after-frame enables a user to the free switching between sitting posture and sprawl as needed, substantially increases Ease of use and operating flexibility；Further through the V-arrangement cantilever being arranged in mounting, improve by left arm rest, right arm rest, side arm, Fixing and stationarity of the mounting that middle frame, after-frame are formed during being used for a long time, and make installation, disassembly, maintenance It is more convenient Deng operating；The manual zero-g chair structure design is dexterous, and practical, cost is relatively low, is suitble to promote and apply.
