Description

Oblique fold chair framework

Technical field:

The utility model relates to a kind of oblique fold chair frameworks.

Background technique:

Folding seat is seat that is light, can stacking function, not only conveniently moved, but also saves space.It is usually used in all kinds of training machines The places such as structure, school and college, public place, hospital, dining room, hotel, company, family.Existing folding seat skeleton structure is complicated And design is unreasonable, there are also be exactly that stability is inadequate；In addition for previous seat when user sits down, backrest can be supported cloth institute Drawing, causes backrest to lean forward, there is the feeling to lean forward when sitting user, to make to take uncomfortable.

Utility model content:

In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a kind of oblique fold seats Skeleton, oblique fold seat framing structure design rationally, are conducive to improve mechanical stability.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of oblique fold chair framework, including Chair frame and support is leaned against, it is preceding X font respectively that the chair frame, which includes the chair bar assembly that four groups of front, rear, left and right are hinged to X font, Chair bar assembly, rear X font chair bar assembly, left X font chair bar assembly, right X font chair bar assembly, each component include middle part phase Mutually hinged fork arm, the support that leans against includes two tilting bars, and the lower end of two tilting bars is respectively hinged at rear X font chair bar The lower end of two fork arm of component, the tilting bar successively include that lower vertical section, middle part are leaned forward section and top hypsokinesis from bottom to top Section.

Preferably, the upper end of above-mentioned rear two fork arm of X font chair bar assembly is respectively articulated with left X word by two first connectors The upper end of shape chair bar assembly, right two hypsokinesis fork arm of X font chair bar assembly, first connector is equipped with perforation, described to incline Brace passes through the perforation.

Preferably, the section that leans forward in the middle part of above-mentioned tilting bar with vertically at 2-5 degree angle, the tilting bar top hypsokinesis section and perpendicular Directly at 7-15 degree angle.

Preferably, on the left-leaning fork arm of lean forward fork arm top and the preceding X font fork arm component of above-mentioned left X font chair bar assembly Portion is hinged through front left connector, the Right deviation on lean forward the fork arm top and preceding X font fork arm component of the right X font chair bar assembly Fork arm top is hinged through front right connector.

Preferably, the lower end of above-mentioned front, rear, left and right X font chair bar assembly fork arm and the lower end of adjacent sets fork arm pass through Foot's connector is hinged.

Preferably, before above-mentioned preceding X font chair bar assembly, Right deviation fork arm upper end is equipped with outwardly extending handrail connection Arm.

The utility model oblique fold chair framework includes that lower vertical section, middle part are leaned forward behind section and top by tilting bar Section of inclining realizes a variety of usage modes, and can increase its stability used so that it be facilitated to adjust different angle use.In addition, Due to the setting of tilting bar, so that have the tendency that hypsokinesis using seat made from the skeleton, after user sits down, the hypsokinesis Trend counteract when sitting down backrest by the movement of preceding drawing, make to sit, be sleeping more comfortable.

Detailed description of the invention:

Fig. 1 is the D structure schematic diagram of the utility model embodiment；

Fig. 2 is the main view organigram of Fig. 1.

Specific embodiment:

In order to make the above-mentioned features and advantages of the utility model more obvious and understandable, special embodiment below, and cooperate attached drawing, It is described in detail below.

The utility model oblique fold chair framework includes chair frame 1 and leans against support 2, the chair frame 1 include it is forward and backward, left, Four groups of the right side is hinged to the chair bar assembly of X font, is preceding X font chair bar assembly 3, rear X font chair bar assembly 4, left X font chair respectively Bar assembly 5, right X font chair bar assembly 6, each component include the fork arm 7 that middle part is hinged, and the support that leans against includes two Root tilting bar 8, the lower end of two tilting bars 8 are respectively hinged at the lower end of 4 liang of fork arms of rear X font chair bar assembly, the inclination Bar 8 successively includes that lower vertical section 801, middle part are leaned forward section 802 and top hypsokinesis section 803 from bottom to top.

Preferably, in order to design rationally, the adjusting of different usage modes, above-mentioned rear X font chair 4 liang of fork arms of bar assembly are realized Upper end be respectively articulated with left X font chair bar assembly, right two hypsokinesis fork arm 10 of X font chair bar assembly by two first connectors 9 Upper end, first connector 9 be equipped with perforation 901, the tilting bar 8 pass through it is described perforation 901, pass through perforation 901 It is set in the different location of tilting bar 8, leans against the different tilt angle of support 2 to realize, realizes seating, lean to etc. that differences make Use mode.

Preferably, in order to design rationally, the section that leans forward in the middle part of above-mentioned tilting bar with vertically at 2-5 degree angle, the tilting bar Top hypsokinesis section with vertically at 7-15 degree angle.

Preferably, in order to design rationally, lean forward fork arm top and the preceding X font fork arm group of above-mentioned left X font chair bar assembly The left-leaning fork arm top of part is hinged through front left connector 14, lean forward fork arm top and the preceding X word of the right X font chair bar assembly The Right deviation fork arm top of shape fork arm component is hinged through front right connector 11.

Preferably, in order to design rationally, the lower end of above-mentioned front, rear, left and right X font chair bar assembly fork arm and adjacent sets The lower end of fork arm is hinged through foot's connector 12.

Preferably, for the ease of supporting user's hand, before above-mentioned preceding X font chair bar assembly, Right deviation fork arm upper end It is equipped with outwardly extending handrail linking arm 13.
