Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment, see accompanying drawing 1,2,3,4, a kind of footrest rack mechanism of chair, the foot-rest 2 comprising footrest rack body 1 and be fixedly connected with described footrest rack body 1 front end, described footrest rack body 1 comprises for the contiguous block 13 being fixed on the fixed support 11 bottom seat cushions, the folding connecting rod 12 be connected with described fixed support 11 and be fixedly connected with described foot-rest 2.
Described folding connecting rod 12 forms by 2-10 root connecting rod 121 is hinged, described connecting rod 121 intersection is arranged in order, be hinged in the position of described connecting rod 121 head and the tail, there is a tie point 122 every two described cross one another positions of connecting rod 121, adopt the mode of foldable push and pull connecting rod 12, described foot-rest 2 is made to stretch out or regain, not only easy to use, and also firmness is better.When described foot-rest 2 stretches out, every two described connecting rods 121 intersect fixing, and this tie point 122 adds that two end points of described connecting rod 121 self define a triangle, and in a plane, triangle is the most stable.
Described fixed support 11 comprise with the holder 111 be fixedly connected with bottom seat cushions, by described holder 111 formed for deposit retract after foot-rest 2 accommodation space 112 and for the fixing screw 113 of described holder 111 bottom seat cushions.Described holder 111 curve one arc, the accommodation space 112 described in formation.The size of accommodation space 112 is slightly larger than described foot-rest 2.
Described holder 111 is provided with the slideway 1 used when folding for described connecting rod 121.Described slideway 1 has two, is positioned at the both sides of described holder 111, and the center line symmetry according to described holder 111 is set up.
Described contiguous block 13 comprises contiguous block body 131, is located at the slideway 2 132 of use when described contiguous block body 131 folds for described connecting rod 121 and the hold-down screw 133 for fixing described foot-rest 2.Described slideway 2 132 also has two, is positioned at the both sides of described contiguous block body 131, and the center line symmetry according to described contiguous block body 131 is set up.
One end of described folding connecting rod 12 is connected with described fixed support 11 by described slideway 1, and the other end is connected with described contiguous block 13 by described slideway 2 132.
Described connecting rod 121 is provided with the slide block 123 coordinated with described slideway 1 and described slideway 2 132.
Described foot-rest 2 is provided with a dismountable second layer foot pad 21.Consider that people are sitting in when chair using foot-rest, some people can feel the height of a foot-rest or comfort level inadequate, therefore add a dismountable second layer foot pad 21, do the size neither affecting described accommodation space 112 like this, height or the comfort level of foot-rest can be increased again.
