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, refer to a kind of armchair structure that can adjust the angle of inclination automatically especially.

Background technology

Most of traditional type seats only are a kind of instruments that human body is taken.For satisfying user's comfort, can establish soft object at seat and people's contact level upper berth usually, but most of seat is designed to lead usually with outward appearance, often ignored seat the real purpose that will reach.Though the height of some seat after can taking with the person of being used through the adjusting device adjustment height of seat of seat bottom in the design; And be provided with fine-tuning chair back part, let the user can be after taking, but such design still belong to passive type mechanism with leaning on back in the chair back; Because every user's height and sitting posture are completely different; Therefore, must adjust desired height and angle of inclination voluntarily, in use very not convenient through the user; Moreover; Because its design only can reach the adjustment of height of seat and chair back gradient; Seat integral body can't change the appropriate tilt angle with user's sitting posture, therefore under the long situation of riding time, 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 adjust the angle of inclination automatically.

For achieving the above object, armchair structure provided by the invention, said 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 first buffer gear, it is arranged between seat and the pedestal;

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

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

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

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

When armchair structure provided by the invention carries human body at seat; Through first buffer gear and second buffer gear buffering human body weight; And through bottom before the seat two stick up shape chair pin, and the pivot of extension rod can be subjected to displacement extension rod backward; And then change the whole angle of inclination of seat, whereby to reach the purpose that cooperates human body sitting posture; In addition, sticking up shape chair pin owing to two of extension setting in bottom before the 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 takes on seat, stick up the roller of shape chair pin and extension rod through 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 change the angle of inclination automatically.

The specific embodiment

In order to reach above-mentioned purpose and effect, will combine accompanying drawing and embodiment to explain as follows below, so that those of ordinary skill in the art can embodiment of 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 that by knowing among the figure this armchair structure includes:

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

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

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

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

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

As shown in Figure 4, wherein in use, two stick up shape chair pin 11 and extension rod 3 one ends roller 31 all adhere on ground; When the user was taken in 1 last time of seat,, and design through the arcwall face that shape chair pin 11 is stuck up in bottom two before the seat 1 earlier through the body wt of first buffer gear 4 with second buffer gear, 5 buffering users; And the pivot of extension rod 3; Let 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 sitting posture.

Wherein, why causing seat 1 to change angle, mainly is because seat 1 is after bearing user's weight; Seat 1 preceding bottom two is stuck up shape chair pin 11 and is carried out the cambered surface motion, so that seat 1 is toward rear-inclined, simultaneously through 5 pairs of extension rods of second buffer gear, 3 generations, one pressure; 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; Second buffer gear 5 also is one of critical piece that causes extension rod 3 displacements except available buffer user's body wt.

In addition; As shown in Figure 5, when the user is taking behind seat 1, owing to pass through first buffer gear 4 and second buffer gear, 5 buffering users' body wt; Therefore; Bear user's body wt at seat 1 after, extension rod 3 is subjected to displacement with speed slowly backward, till seat 1 tilts to specific angle; Moreover body's center of gravity changes when taking along with the user owing to the angle of inclination of seat 1, so when tilting as if user's body forward, extension rod 3 is regained displacement forward, and then makes seat 1 revert to milder angle.

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

In sum, more than being merely preferred embodiment of the present invention, is not therefore to limit scope of patent protection of the present invention, and claim of the present invention must be as the criterion with the content of claims.
