Abstract

The invention relates to a seat structure, comprising a seat, a substrate, an extending rod, at least one first cushion mechanism and a second cushion mechanism. When bearing human, the seat structure provided in the invention cushions the human weight through the first cushion mechanism and the second cushion mechanism; the extending rod can displace backwards by two raised chair feet on the ground and pivoting the extending rod; and the seat changes the inclined angle automatically so as to achieve the purpose of matching with human sitting posture.

Description

A kind of armchair structure

Technical field

The present invention relates to a kind of armchair structure, the espespecially a kind of armchair structure that can automatically adjust the angle of inclination.

Background technology

Most of traditional type seats are only a kind of instruments that human body is taken.For satisfying user's comfort, usually can establish soft object on seat and people's contact level upper berth, but most of seat is designed to lead usually with outward appearance, often ignored the real purpose that seat will reach.The height after although some seat can be taken with the person of being used in conjunction with by the adjusting device adjustment height of seat of seat bottom in design, and be provided with fine-tuning chair back part, the user back can be leaned in the chair back after taking, but such design still belongs to passive type mechanism, because every user's height and sitting posture are completely different, therefore, must be by user's Self-adjustment desired height and angle of inclination, very not convenient in use; Moreover, because its design only can reach the adjustment of height of seat and back inclination, seat integral body can't change with user's sitting posture suitable angle of inclination, therefore in the situation that riding time is long, for the user, except producing discomfort, also can have a negative impact to vertebra health.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of armchair structure that can automatically adjust the angle of inclination.

For achieving the above object, armchair structure provided by the invention, described armchair structure includes:

By a seat, the bottom is extended and is provided with the two corresponding shape chair pin that stick up before it;

One pedestal, it is located at seat bottom;

One extension rod, it is articulated in base bottom;

At least one the first buffer gear, it is arranged between seat and pedestal;

At least one the second buffer gear, it is articulated between base bottom and extension rod.

As preferred version, wherein said extension rod is provided with a roller at the other end of pivot joint base bottom.

As preferred version, be provided with at least one elastic parts in wherein said the first buffer gear.

As preferred version, wherein said the second buffer gear is oil hydraulic cylinder or pneumatic cylinder.

Armchair structure provided by the invention is when seat carrying human body, by the first buffer gear and the second buffer gear buffering human body weight, and stick up shape chair pin by two of bottom before seat, and the pivotable of extension rod, extension rod can be subjected to displacement backward, and then the angle of inclination of change seat integral body, whereby to reach the purpose that coordinates human body sitting posture; In addition, sticking up shape chair pin due to two of extension setting in bottom before seat is arc shape, and extension rod is provided with a roller at an other end that is hubbed at base bottom, therefore, when the user rides on seat, stick up the roller of shape chair pin and extension rod by adhering on two of ground, when changing sitting posture, extension rod can be easily and the displacement that successfully extends back, and makes the seat can be according to user's sitting posture and automatically change the angle of inclination.

The specific embodiment

In order to reach above-mentioned purpose and effect, be described as follows below in conjunction with drawings and Examples, so that those of ordinary skill in the art can implement the present invention according to the following stated.

See also Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, be respectively stereo appearance figure of the present invention, three-dimensional exploded view, partial schematic diagram and preferred embodiment figure, find out by knowing in figure, this armchair structure includes:

One seat 1 is taken for the user, and before it, bottom and extending is provided with the two corresponding shape chair pin 11 that stick up;

One pedestal 2, it is located at seat 1 bottom;

One extension rod 3, one end are articulated in pedestal 2 bottoms, and the other end is provided with a roller 31;

At least one the first buffer gear 4, it is arranged between seat 1 and pedestal 2, and its inside also is provided with at least one elastic parts 41;

At least one the second buffer gear 5, it is articulated between pedestal 2 bottoms and extension rod 3, and it is oil hydraulic cylinder or pneumatic cylinder.

As shown in Figure 4, wherein in use, two rollers 31 that stick up shape chair pin 11 and extension rod 3 one ends all adhere on ground, when the user rides on seat 1, first by the body wt of the first buffer gear 4 with the second buffer gear 5 buffering users, and design by the arcwall face that shape chair pin 11 is stuck up in seat 1 front bottom two, and the pivotable of extension rod 3, allow extension rod 3 displacement that can extend back, and then make seat 1 angle that tilts, to reach the purpose of the person's of being used in conjunction with sitting posture.

Wherein, why cause seat 1 to change angle, mainly because seat 1 is after bearing user's weight, the front bottom two of seat 1 is stuck up shape chair pin 11 and is carried out the cambered surface motion, so that seat 1 is toward rear-inclined, produce a pressure by 5 pairs of extension rods of the second buffer gear 3 simultaneously, after making extension rod 3 produce the displacement of a special angle, being able to can supporting chair 1, and seat 1 is remained on this angle, therefore, the second buffer gear 5 except available buffer user's body wt, is also one of critical piece that causes extension rod 3 displacements.

In addition, as shown in Figure 5, after the user is riding on seat 1, due to the body wt by the first buffer gear 4 and the second buffer gear 5 buffering users, therefore, bear user's body wt at seat 1 after, extension rod 3 is subjected to displacement backward with speed slowly, until till seat 1 tilts to specific angle; Moreover when taking along with the user due to the angle of inclination of seat 1, the center of gravity of health changes, therefore, if when user's body forward tilted, extension rod 3 was regained forward displacement, and then makes seat 1 revert to milder angle.

Said structure, compared to general traditional seat only capable of regulating chair height and the fine setting chair back, the present invention is after the user takes, buffering by the first buffer gear 4 and the second buffer gear 5, and the shift reciprocately of extension rod 3, make seat 1 integral body automatically change the angle of inclination along with user's sitting posture center of gravity, the comfort in the time of therefore can satisfying the user and take.

In sum, these are only preferred embodiment of the present invention, not thereby limit scope of patent protection of the present invention, the scope of the claims of the present invention must be as the criterion with the content of claims.
