The seat furniture comprises a support, a backrest and a seat board, wherein the backrest and the seat board are arranged on the support and mutually hinged. The backrest is movably connected with a fixed shaft on the support, and at least one rolling structure and a slide guiding structure are further arranged between the seat board and the support, wherein the rolling structure is used for adjusting the seat board to move forwards and backwards, and the slide guiding structure matches with the rolling structure. The seat furniture can effectively decrease the frictional force of the backrest and the seat board when in angle adjustment, thereby leading the adjustment to be easier and more flexible and avoiding breakage of devices.
Description
Technical field
The utility model belongs to the furnature construction technical field, relates in particular to a kind of chair that link gear is rolled in free skating that has.
Background technology
At present, known chair governor motion is to be formed by a baroque linkage combination.Because the complex structure of linkage causes the weight of link gear big, and require to use high-intensity, a fairly large number of material has limited the scope of application of chair, has improved production cost simultaneously.In addition, the adjusting of general link gear needs staff to cooperate the control angle of inclination, and ease of use remains further to be strengthened.
China utility model patent CN 97211832.2, name is called the backrest stepless regulator of chair, it discloses a kind of backrest stepless regulator of chair, it is made up of slide bar, sliding sleeve and hinge cover, the slide bar of making dihedral can slide in the hole on sliding sleeve, sliding sleeve is connected for hinge with hinge cover, be installed on the chair after, can be automatically the luffing angle of backrest be carried out step-less adjustment.Though this technology has changed the linkage of traditional structure complexity, it adopts the fit structure of slide bar and sliding sleeve, and its frictional force is bigger, make the angular adjustment of backrest and seat board become clumsy, and long-term big frictional force also will cause bigger infringement to parts.
The utility model content
At the shortcoming of prior art, the purpose of this utility model provides a kind of frictional force of the angular adjustment that can effectively reduce backrest and seat board and simple in structure has a chair that link gear is rolled in free skating.
For achieving the above object, the technical solution of the utility model is: a kind of have a chair that link gear is rolled in free skating, comprise support and be located at backrest and seat board on the support, this backrest and seat board are hinged, this backrest flexibly connects with the fixed axis of being located on the support, also is provided with at least one between this seat board and the support and is used to regulate seat board and does rolling structure that moves forward and backward and the slide guide structure that cooperates with rolling structure.
In this programme, when the user toward backrest by or when before seat board, sitting up, will reach the effect of free adjustment backrest and seat board balance angle by the rolling structure and the relative slip of slide guide structure.Owing to adopt the fit adjustment structure of rolling structure and slide guide structure, the frictional force in the time of effectively reducing its free adjustment makes that adjusting is lighter, flexible, avoids the breakage of device.And slide bar and sliding sleeve fit system that prior art adopts, its frictional force is sliding friction, and is bigger more than the rolling friction of this programme.
For slide guide rolling structure more swimmingly, this slide guide structural design is a shaped form slide guide structure.Because backrest and seat board are in the dynamic adjustments process, the pin joint of this backrest and seat board leans around the back of the body and does curvilinear motion with the fixed axis of support, therefore the curvilinear path motion that seesaws and also can follow mitigation of this seat board, this shaped form slide guide structure can make and bear less pressure between slide guide structure and rolling structure, so can effectively reduce both frictional force.This slide guide structure also can be designed to linear slide guide structure.
This slide guide structure is located on the seat board, and this rolling structure is located on the support.
As a kind of structure wherein, this slide guide structure is a slide rail, and this rolling structure comprises the roller that cooperates with slide rail, the axle screw rod and the fixed axis screw rod turning rolls that are connected with roller, and this turning rolls is fixed on the support.
Depart from the motion track path for fear of the slide guide structure, also be provided with a gag lever post that is used to limit slide guide structure lengthwise position on this turning rolls.
As another kind of structure wherein, this slide guide structure is the double sided slider bar structure, and this rolling structure is two rollers that double sided slider bar cooperates.
As another kind of structure wherein, this slide guide structure is the grooved rail structure, and this rolling structure is single roller structure.
Further, the front and back ends of this slide guide structure is provided with the position limiting structure that is used to limit rolling structure, and this position limiting structure can limit the angle between backrest and the seat board, and best angle when being fit to the people and lying low or sit straight according to ergonomics design.
Particularly, this support is door type structure, and the fixed axis that this backrest and support flexibly connect is positioned at the upside rear end corner of this door type structure.
As a kind of alternative structure, this rolling structure also can be located on the seat board, and this slide guide structure is located on the support.
The utility model compared with prior art has following advantage and beneficial effect:
The utility model can change immediately following seat user's position by backrest and seat board adjusts gradient and height automatically, for the user provides comfortable sitting posture.The structure of the chair link gear of simplifying greatly is control production cost, the prerequisite that the management and control product quality provides simultaneously.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
As Fig. 1 a, 1b, 1c, Fig. 2 and shown in Figure 3, the utility model discloses a kind of chair that link gear is rolled in free skating that has, comprise support 1 and be located at backrest 2 and seat board 3 on the support 1, this backrest 2 is hinged with seat board 3, this backrest 2 flexibly connects with the fixed axis of being located on the support 14, also is provided with at least one between this seat board 3 and the support 1 and is used to regulate the rolling structure that seat board 3 does to move forward and backward and reaches the slide guide structure that cooperates with rolling structure.
In the present embodiment, the quantity of this rolling structure and slide guide structure is two, and be distributed in the end positions between seat board 3 and the support 1, fixed axis 4 on this backrest 2 and the support 1 connects for fixed hinge, backrest 2 uses general hinge to connect with seat board 3, this slide guide structure is located on the seat board 3, and this rolling structure is located on the support 1.
Certainly, the quantity of this rolling structure and slide guide structure also can be one, and is distributed in the medium position between seat board 3 and the support 1.
The realization principle is: when the user was seated at seat, the health position changed, and causes center of gravity to change, and provided power for promoting backrest 2 or seat board 3.When user's leans back, the back to backrest 2 firmly, move after the center of gravity, thrust is on backrest 2, and backrest 2 recedes, and promotes seat board 3 to front slide by hinge simultaneously, after position moves and stops, center of gravity reaches a new balance, and backrest 2 and seat board 3 reach freely regulated effect with stop motion.When the user sits up forward, backrest 2 is left at the back, the center of gravity reach, gravity acts on the seat board 3, and seat board 3 slides backward along the slide guide structure under gravity, and rotates forward by hinge promotion backrest 2, after position moves and stops, center of gravity reaches a new balance, and seat board 3 and backrest 2 reach freely regulated effect with stop motion.
