Abstract
The utility model discloses a pull structure which relates to the improvement of the adjusting mode of various adjustable backrest chairs. The utility model pushes out a kind of pull structure whose left and right groups are identical, and the pull structure commonly supports a backrest, a cushion and a lower leg cushion surface; each group are all through 21 special-shaped connecting pieces. Each two connecting pieces are connected in the special position of a movable shaft without any additional power or manmade additional auxiliary adjustment; however, sitting postures only can be changed by users to select an optimum angle. Under the natural sitting and lying force functions of human bodies, the sitting or lying pull structure is accepted by social public through optimal comfortableness, convenient use, and the multi-combined universality of a wide application range structure.
Description
The utility model relates to the improvement of the regulative mode of all kinds of adjustable backrest seats.
Existing all kinds of backrest seat as chaise longue, sofa, hairdressers' chair, dental chair etc., is not to adopt mechanical type adjusting manually, adopts the electronic regulative mode of Denging exactly, puts or attitude to change its seat clinostatism.Given this present situation further satisfying the optimum reelability quality that the user has a rest, and is more convenient for using.
The purpose of this utility model is will release a kind ofly to need not any additionaling power equipment or artificial add the mechanical type auxiliary operation and can sit under the effect of the power of crouching the human body natural, make backrest face, cushion surface, shank pad face with the change of human bodily form's posture interlock inclination angle thereupon.Just, simplified dexterity to greatest extent and operated easily, to reach best pull-type structure of sitting the level of comfort that crouches with new version.
The utility model is to realize like this.Promptly by about two groups identical, connect with two connecting rods, every group all by 21 given shape steel in flakes, therebetween with the connection of movable axis ad-hoc location, be combined into vertically interlock expansion or withdrawal, to change the basic frame structure at backrest face, cushion surface, shank pad face position and the inclination angle of holding in the palm its top.Its every group comprises 1 horizontal base bridge respectively, the support of 2 support mass activity structures in flakes before and after having on the end bridge, 2 supports connect by 3 cross transitions at middle part again in flakes in flakes, 3 transition in flakes again by 8 vertically, 4 horizontal servo-actuateds in flakes, connect in flakes with 3 upper ends that are connected back cushion, cushion, 3 faces of shank pad of upper end.And, sit the limit that clinostatism is put to control it by going up 3 outside, 2 inside setting circle shelves in flakes.When the people desires to transform to when lying on the back shape from sitting posture, only need upper body is swung back, can spend 135 degree of swinging back from 105, rear upper end in flakes thereupon hypsokinesis press down, promote the rear portion vertically in flakes, it promotes 3 cross transitions forward in flakes again, and it drives other servo-actuated in flakes again, the cushion bottom that makes the upper end in flakes, inclination angle, the expansion in flakes of the rebasing portion of shank.Even steeve in the cushion surface front portion, little leg cushion is by former upright position, and 90 degree that raise up hold up shank.When the people when the shape of lying on the back transforms to sitting posture, also only need pressure pad shank under the calf, its upper end that connects below in flakes with within receive, and drive other oppositely interlock withdrawal restore to the original state (course of action is opposite with expansion) in flakes successively.Be that 3 of people back, thigh and buttocks, calf support dependence face, can sit the prone position attitude with human body to change, under human body natural's seat crouched the power effect, interlock thereupon changing the gradient of 3 faces, or was in normal sitting position, or is in the resting state of lying on the back.
The utility model is abundant application engineering structural mechanics principle in wherein, by about two groups of 21 identical given shapes in flakes, it is each other with the connection of movable axis ad-hoc location, and reaches best result of use.Its manufacturing process is simple, and the structure action is light and handy, and it is very convenient to use.Because of need not any additionaling power, or the people is the mechanical type auxiliary operation that adds, and only needs the light natural action of user self, changes the prone position formula of sitting, just can make backrest face, cushion surface, the shank pad face of the backrest seat of this pedestal structure moving thereupon, or seat or for sleeping in.Be hypsokinesis 105 degree of backrest during by sitting posture, 135 degree of can swinging back.The cushion front portion also raises up simultaneously, little leg cushion former vertical status during also by sitting posture, and 90 degree that raise up hold up shank.Be bordering on three sections face angles of plane integral body during this lying on the back, increased seating surface greatly than sitting posture, pressurized when having avoided buttocks, the thigh bottom of long-term sitting posture long, the poor blood circulation that is brought has further loosened the muscle of cervical vertebra, lumbar vertebrae, thoracic vertebrae and each joint and each anxiety of whole body.Muscle has been loosened in the picking-up of shank too, has quickened the blood backflow.No matter be of a specified duration for standing, or the people of sitting posture when long, the resting chair that this easy adjustment structure is formed, the good assistant that the rest of the best of then can yet be regarded as recovers, and safe and reliable, all-ages.
The mapping mode of this novelty is that the adjustment structure and the mode of existing chair class is short of.This structure has also brought it to adapt to wide characteristics thus: can be combined to adjustable backrest seat, office chair, executive chair.Also can be combined to the adjustable type of sofa.Also can be combined to hairdressers' chair, dental treatment chair.Or be combined as disabled person's wheelchair, the increase of medical sick bed function.No matter be promptly from level of comfort, easy to use, or many combinations versatility of its structure adaptive surface, all reached optimum state.
