In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are more clearly understood, with
Under in conjunction with the embodiments and accompanying drawing, the utility model is further elaborated.It is it should be appreciated that specific described by this part
Embodiment can only be used to explain the utility model, be not used to limit the utility model.
Specific embodiment one
As shown in Figure 1 and Figure 2, the preferred embodiment discloses a kind of chair 100, including the seat board 110 for user's seating
With the supporting mechanism 120 for supporting the seat board 110, the seating face 111 of seat board 110 tilts down along user's seat direction, made
It must take in an acute angle between face 111 and horizontal plane, the acute angle scope is more than 0 ° and less than between 35 °.It is sharp in the present embodiment
Angle selects 14 °.In other embodiments, the preferred scope of acute angle in 6 ° -16 ° or preferred scope at 7 ° -15 °.It is highly preferred that
Acute angle is arranged to 13 ° or 15 °.
Wherein, when user's seat direction refers to that user is sitting on chair 100, the direction that faces；Seating face 111 is appreciated that
When being sitting in for user on chair 100, the front end low spot and the gradient that is formed of rear end high point of the plane of hip contact seat board 110
Face, it is that seating face 111 is presented to prolong a liter trend in user's seat direction the purpose of the presence in this gradient face.Wherein front-end and back-end
All referring in user's seat direction, user plane pair be before, after what back leaned on is.
As shown in Fig. 2 in the present embodiment, seat board 110 is provided with angle positioning device I 130, angle positioning device I 130
Including the chuck 131, keeper 132 and the connector 133 for connecting supporting mechanism 120 being fixed on seat board 110, connector 133
One end and chuck 131 it is spacing for the first time by the completion that is rotatably connected of connecting shaft 134, then keeper 132 to chuck 131 with even
Rotation progress between fitting 133 is secondary spacing, seat board 110 is limited to the preset angular positions of above-mentioned acute angle scope.
As shown in figure 1, in the present embodiment, keeper 132 is telescopically located on connector 133 by flexible member, card
Disk 131, which is provided with, is suitable to the connecting hole 1311 that keeper 132 inserts, when a part for keeper 132 is in connecting hole 1311,
Pass through the secondary spacing of the once spacing and keeper 132 of connecting shaft 134, so that it may limit the rotation of chuck 131.In other implementations
In example, connecting hole 1311 can also use the set-up mode of breach.
Similarly, in other embodiments, as shown in figure 3, keeper 132 can also be telescopically located at by flexible member
On chuck 131, connector 133, which is provided with, is suitable to connecting hole or breach that keeper 132 inserts, at a part for keeper 132
When in connecting hole or breach, the rotation of chuck 131 can be limited.
As shown in Fig. 2 supporting mechanism 120 include the support base 121 that is contacted with ground and be connected to support base 121 and
The angular range of support rod 122 between seat board 110, support rod 122 and horizontal plane is at 20 ° -35 °.In the present embodiment, supporting
The angle of bar 122 and horizontal plane is set to 26 °, and support base 121 is made up of two rod-like structures, triangular in shape.Also set in support rod 122
There is sleeve 123, connector 133 is suitable to be set in sleeve 123, to support seat board 110.
As shown in Figure 1 and Figure 2, it is additionally provided between the attachment structure of seat board 110 and supporting mechanism 120 for adjusting seat board 110
The lifting regulating mechanism I 140 of terrain clearance.For example, the seat board 110 in Fig. 2 is higher by 13cm than the seat board 110 in Fig. 1.This implementation
In example, lifting regulating mechanism I 140 is the mechanism that lifting is realized by way of regulating part fastens elevating lever.Specifically, pass through
The elevating mechanism realized of mode of regulating part fastening elevating lever specifically by sleeve 123, be actively plugged in sleeve 123 and be used to realize
The connector 133 and fastener 141 of lifting form.Wherein, sleeve 123 is provided with breach, and fastener 141 is used to lock breach
Realize that sleeve 123 is held with a firm grip connector 133, prevents connector 133 to be moved.Wherein, sleeve 123 holds the position of connector 133
The flexible piece of increasing friction force, such as rubber can also be set by putting.In other embodiments, lifting regulating mechanism I 140 can also be adopted
With pressure liftable post commonly used in the prior art or the lift of screw lifting mechanism or latch and multi-hole position structure mates
Structure.The elevating mechanism of latch and multi-hole position structure mates is that latch matches with the structure provided with multiposition hole, passes through choosing
The annexation for selecting latch and location hole rises or dropped to limit.
As shown in figure 4, the chair 100 in the present embodiment also includes backrest 150, backrest 150 is provided close to the position of seat board 110
Put, and backrest 150 is located at the rear of user's seat direction.The angular range formed between backrest 150 and vertical plane preferably exists
0 ° -16 °, selection is 3 ° in the present embodiment.Fixture 124 is removably connected with support rod 122, fixture 124, which is provided with, to be used
In the knee plate 160 of support knee, in user's seat direction, knee plate 160 is located at the front of seat board 110.Knee plate 160 passes through
On fixture 124, knee plate 160 161 can rotate freely around the shaft for rotating shaft 161.
In the present embodiment, also include handrail 170 in the both sides of seat board 110, the setting of handrail 170 refer to Fig. 7.
Because the seating face 111 of seat board 110 tilts down along user's seat direction so that take face 111 and horizontal plane it
Between it is in an acute angle, the acute angle scope is in the range of possible angle, so compared with prior art, the seating face tilted down 111 can
So that seat board 110 preferably leaves the artery on user's thigh, the thigh of user is set to can be at nature laying state, beneficial to user
Health.In addition, user is sitting on the seating face 111 tilted down, to prevent hip from being slided from seat board 110, it is necessary to steady
The fixed center of gravity of oneself., can be subconscious by body leans back in this way, user is makes oneself to sit comfortable, so i.e. usable family
Body muchly keeps straight, and lumbar vertebrae is in normal physiological curve state, prevents disc herniation.Again due to the height of seat board 110
Degree and sharp angle can be adjusted voluntarily, so user can make the body of oneself be in most comfortable by the regulation of height and angle
State.In the present embodiment, due also to the setting of knee plate 160, user can make the artery of thigh preferably away from seating face
111, provide the user a kind of new chair Ride Style.The specific seating situation of user refer to Figure 10.
It is comfortable to take user, the cushion of softness can also be set on seat board 110 and knee plate 160.In addition, do not setting
During cushion, for ease of user be sitting on seat board 110 after air circulation, seating face 111 may be configured as increase frictional force concave surface or
Convex surface.The setting on concave surface or convex surface refers to Fig. 1.
Above example is only a kind of preferred embodiment, in other embodiments, the positioning of angle positioning device I 130
