Abstract
The utility model relates to a three-dimensional adjusting health chair, which belongs to the improvement of a chair and mainly comprises a chair frame, a chair surface, a sliding frame, a rotating frame and other multi-rod mechanisms. The chair can simultaneously and interlockingly adjust the height of the chair surface, the depth of the chair surface and the height of the chair back according to the needs of a user, meets the physiological requirements of the human body, is favorable for the health of the user, has simple structure and low manufacturing cost, is particularly suitable for students in middle and primary schools to study, sit when having a rest, and can be used by various personnel with different heights to work and study.
Description
The utility model relates to a kind of seat height, seat reaches the chair that chair back high energy is regulated simultaneously deeply, belongs to the improvement of chair, is particularly suitable for primary and secondary students and sits usefulness.
Although general to sit the chair style structure of usefulness for work, study different, have highly fixingly, also have adjustable for height.Just seat is Height Adjustable with regard to adjustable for height chair, and two other important indicator seat that relates to chair reaches the then corresponding adjusting simultaneously of chair back height deeply.When the teenager sat with this chair, height and corresponding chair height were guaranteed, but can not make full use of the function of the chair back.Utilizing chair back study or have a rest must be moving behind the buttocks, and knee rides on the seat, the shank perk, and waist can not rationally rest on the chair back, and this incorrect sitting posture has certain harm to sitting with person's health.From hygiene of children and adolescents as can be known, the teenager sits the chair of usefulness, and its height and seat height, seat reach between the chair back high four deeply should reasonable coupling, sits like this to use just and can feel comfortably cool, and reduces fatigue, helps healthy.State Standard of the People's Republic of China's " school desk's chair functional dimension " (GB3976-83) has a respective specified to this.If the teenager sits for a long time with not guaranteeing simultaneously that its height and seat height, seat reach the high chair of coupling rationally of the chair back deeply, will influence the normal development of bone, increase fatigue, endanger healthyly, so this class chair has improved necessity.
The purpose of this utility model is to provide a kind of and can changes with the user of different heights and regulate nursing chair with the three-dimensional that its height is complementary.
The utility model is achieved by the following technical solution: two moving chair framves that have an angle of bend, decide the chair frame and be hinged, moving chair frame is housed on the sliding axle, regulate pulling-on piece and and sliding sash on corresponding recesses coincide, it is hinged successively by pivoted frame, chair back pulling-on piece, chair back rack to regulate pulling-on piece, chair back rack is being sliding-contact in the chair back sleeve pipe at β angle with seat, and angle beta is in 40 ° of-45 ° of scopes.Sliding axle moving chair frame, decide chair frame, adjusting pulling-on piece, pivoted frame and chair back pulling-on piece and is moved and rotate in sliding sash when mobile, and chair back rack moves at chair back sleeve pipe cathetus.
Above-mentioned moving chair frame, the bent angle alpha of deciding the chair frame is in 15 ° of-20 ° of scopes, the effect of bringing is to guarantee that dimensionally sliding sash arranges out 6 with upper groove, realizes meeting 6 of national standard with adjusted retaining time and can make the displacement in whole adjustment process of chair frame touchdown point be no more than 20 millimeters.
The utility model compared with prior art has seat height, seat to reach the function that chair back high energy is regulated simultaneously deeply, meets the Human physiology requirement, helps juvenile healthy, and is simple in structure, is beneficial to advantages such as implementing popularization.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the utility model is regulated back mechanism variation schematic diagram.
Fig. 3 is the main TV structure schematic diagram of the utility model localization part.
Fig. 4 is the left TV structure schematic diagram of the utility model localization part.
Fig. 5 is the main TV structure schematic diagram of the utility model pivoted frame.
