The specific embodiment

Head sees also Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, and wherein this Fig. 1 discloses the utility model upset folding mechanism 3 and is applied to the enforcement state diagram in the dining chair.

This dining chair includes both sides carrier unit 1, and respectively this side stand unit 1 includes a bipod 11,12 and a link component 13, and respectively this side stand unit 1 forms the shape of falling V; Dispose two connecting rods 14 again between said this both sides carrier unit 1 in addition.

On described respectively this foot rest 12, all be provided with a upset folding mechanism 3.

Respectively be somebody's turn to do upset folding mechanism 3, mainly include a fixed body 31 and a turnover body 32, wherein:

These fixed body 31, one sides are provided with a setting element 311, and this setting element 311 can be adjusted and locking action with respect to the position of foot rest 12 to reach fixed body 31 in order to lock with respect to foot rest 12 or to discharge; This fixed body 31 laterally offers a location recess 312 again; This location indentations 312 is the perforation shape; In this location indentations 312 from inside to outside in regular turn group be equipped with a flexible member 313 and a driving element 314 one outside, and these location indentations 312 interior ring edges are provided with one or more exterior bayonet slot 3121, this driving element 314 encircles edge and is provided with one or more outer shell fragment 3141 simultaneously; Order should place this exterior bayonet slot 3121 for 3141 groups by outer shell fragment; Forming this driving element 314 can move in 312 of this location indentations are inside and outside, and utilizes the setting of this outer flexible member 313, under the normality this driving element 314 is had an outside active force; These fixed body 31 1 medial surfaces are provided with an axis body 315 in addition; Be provided with a retaining portion 316 in this location indentations 312 again, this retaining portion 316 is positioned at outer flexible member 313 inner edge places; These driving element 314 medial extremitys are provided with projection 3142 in addition.

These turnover body 32, one side central authorities are provided with a mouth 321, and in these mouth 321 both sides, correspondence is concaved with one first recess 322 and one second recess 325; Wherein in this first recess 322; Group is equipped with one first flexible member 323 and one first locking member 324 in regular turn from inside to outside; And these first recess, 322 interior ring edges are provided with one or more first draw-in groove 3221; These first locking member, 324 ring edge are provided with one or more first shell fragment 3241 simultaneously, make 3241 groups on this first shell fragment place this first draw-in groove 3221, and forming this first locking member 324 can be in 322 inside and outside moving of this first recess; And utilize the setting of this first flexible member 323, this first locking member 324 has an outside active force under the normality; Again; In this second recess 325; Group is equipped with one second flexible member 326 and one second locking member 327 in regular turn from inside to outside, and these second recess, 325 interior ring edges are provided with one or more second draw-in groove 3251, and this second locking member 327 encircles edge and is provided with one or more second shell fragment 3271 simultaneously; Make 3271 groups on this second shell fragment place this second draw-in groove 3251; Forming this second locking member 327 can move in 325 of this second recesses are inside and outside, and utilizes the setting of this second flexible member 326, and this second locking member 327 has an outside active force under the normality; This second locking member 327 is provided with an oblique surface 3272 again.

Like Fig. 1-shown in Figure 5; The state that this upset folding mechanism 3 folds; Seat cushion unit 5 is a serviceable condition at this moment; This first locking member 324 receives the outside active force of first flexible member 323, makes these first locking member, 324 external end edges can be absorbed in ora terminalis in the location indentations 312, and this upset folding mechanism 3 presents safe lock-out state.

In the time will folding with regard to seat cushion unit 5; Like Fig. 3, Fig. 5, press driving element 314 with hand, outer flexible member 313 is compressed; The interior projection 3142 of these driving element 314 medial extremitys will move towards first locking member 324 simultaneously; Cause first locking member 324 to be passed this location indentations 312, promptly remove the lock-out state of this upset folding mechanism 3 this moment, just this turnover body 32 can be overturn with respect to fixed body 31 (like Fig. 6, Fig. 7, Fig. 8).When turnover body 32 is turned to the end with respect to fixed body 31; Promptly as shown in Figure 9; This second locking member 327 will get into location indentations 312, and utilizes the active force of second flexible member 326, makes this second locking member 327 after getting into location indentations 312, can form locking really; Can't deviate from arbitrarily, this upset folding mechanism 3 presents safe lock-out state (Figure 10).

After folding, if when will be again seat cushion unit 5 being launched to use, only need to press again and press driving element 314, make the interior projection 3142 of its medial extremity remove to promote second locking member 327 again and deviate from location indentations 312 and get final product, it is quite convenient that use is operated.

The utility model is owing to be arranged with two first joints 521 and two second joints 522 at the quadripolar corners of the seat board 51 of seat cushion unit 5, so when folding, and whole seat cushion unit 5 can both the synchronous change angle, in order to folding.

In sum, the utility model upset folding mechanism, its technology contents meets the important document of obtaining of novel patent fully.The utility model is able to utilize on industry really, before application, has not been shown in publication or public use, and non-ly is technology that the public knew.Moreover the utility model effectively solves the medium-term and long-term problem that exists of prior art and reaches the demand of relevant user and long term consumer, and must prove novel is not to accomplish easily

Just the above is merely this novel embodiment, when can not with the novel scope implemented of qualifications basis.The equalization of promptly doing according to this novel claim generally changes and modifies, and all should still belong in the scope that this novel patent contains.
