Fig. 2 is the stereogram of the bar of full interlock folding seat described in the utility model.

The specific embodiment

Referring to Fig. 1, full interlock folding seat described in the utility model comprises bench and backrest.Described bench has two rectangular frames 1, described rectangular frame by two folding bars 3: the cross-bar assembly 2 that intersect to constitute connects, the two ends of a folding rod 3 in the cross-bar assembly that intersects are connected with the cross tube of rectangular frame 1 by hinge 5, the two ends of another root folding rod 4 are sleeved in the vertical rod 8 of rectangular frame 1 by sliding sleeve 6, therefore, folding rod 4 can rotate around cross tube, and along with the swing of folding rod 4, the folding rod 3 with sliding sleeve is just mobile in vertical rod 8.Cross tube at rectangular frame 1 is installed a rectangular cloth cover, becomes the seat surface of chair.Described backrest comprises two bars 13 and is sleeved on two backrest covers on the bar, is connected with the vertical rod 8 of two rectangular frames by hinge 10 by bar 3.Therefore bar 13 can be around hinge through, or stands on the top of rectangular frame, or rotates after 180 ° near the inboard of hinge and adjacent with vertical rod 18.

Two folding rods 3 of described cross-bar assembly 2,4 are linked together by two rotating shafts, and therefore the cross-bar assembly 2 that intersects can change its intersecting angle easily.

When sliding sleeve 5 upwards slided, two rectangular frames 1 were separated from each other, and cloth spare is tightened, and formed seat surface.When sliding sleeve 5 during to lower slider, rectangular frame 1 is close mutually, and seat surface cloth spare is unclamped, just the state turned up of chair.

Described cross-bar assembly 2 is at the applicant's US8, and is open in 011, the 686B2 patent document.

The vertical rod of described rectangular frame 2 is vertical, is used for load-bearing.Pressurized in the work should have enough intensity by chair, and is light again, so vertical rod can be used light-wall pipe, can make that own wt is very light to bear enough weight again.

The h type that is shaped as of described bar 3, two columns of h type are installed on the column by hinge.

By hinge pull bar 14 is installed between described bar 13 and the sliding sleeve 6, this pull bar should satisfy when full interlock folding seat is in the use state with the position that is connected the center of bar 3, pull bar 14 is connected the center with bar 3 upright position is in the inboard of bar 3 centers of rotation, namely near a side of seat surface cloth spare, make bar 3 that the moment of torsion that turns to the inside be arranged, to keep bar 3 can not flip to the outside automatically, just chair is self-locking when open mode, to guarantee chair being perfectly safe in use.

When chair is in when organizing work state, sliding sleeve 6 is pulled to the upper end, thereby makes two cross-baves 3,4 be in maximum deployed position, tightens sitting cloth, at this moment backrest cloth is contained on two bars 3, and chair just is fixed to duty.Otherwise take off backrest cloth, the outwards upset downwards of two bars, 3 difference, spur pull bar 14 promotion sliding sleeves 6 simultaneously and move downward, make cross-bar 3,4 be in closed condition, chair has been folded up, and the chair after folding just is in minimum volume.From the above mentioned as can be known, chair described in the utility model is opened and folded all is all to link, so be called full interlock folding seat.
