Description
Technical field
The present invention relates to a kind of chair pin, espespecially a kind of light weight can keep the chair pin of the office seats of structural strength simultaneously.
Background technology
Please refer to U.S. Patent number the 4th, 767, No. 159 Patent Cases " CHAIR HAVING SUPPORTING MEMBER FOR THE POSTERIOR AND THE SHINS; RESPECTIVELY; OF A CHAIR OCCUPANT ", this Patent Case has disclosed a kind of office seats, it has a pedestal (base member) in the bottom, this pedestal has four or five pin (leg), this pin can fabricated sheave (roller means), the function that this pulley can provide seat to move.But the pin of this pedestal is solid attitude shape, although have stronger structural strength, but make for difficult and the cost higher cost of all seeming on making with metal or plastic material, moreover, solid pin is also heavier on weight, also quite inconvenience when transporting.
Also has a kind of at present common chair pin, this chair pin can provide support office seats and several pulleys are installed, this chair pin includes a central pedestal, and several are from the extended assembling arm of this central authorities' pedestal, this chair pin has a top and a bottom, this top is towards office seats, this bottom is towards ground, this assembling arm is the outer peripheral face by an assembled wall of this central authorities' pedestal, extend towards radial outer end the equal angles compartment of terrain, each assembling arm comprises: the pulley assembled portion with this central authorities pedestal interval, two intervals and the rough sidewall that connects this pulley assembled portion and this central authorities' pedestal along outrigger shaft direction extension, and several are in this central authorities' pedestal of the radial connection in bottom and assembling arm and the oblique rib that is connected between this sidewall.
In order to take into account the demand of light weight and structural strength, so this assembling arm is not solid setting, but the form that adopts rib to design so that this chair pin has under the advantage of light weight, can reach certain structural strength simultaneously.And above-mentioned chair pin is when other member that cooperates chair uses,
Central shaft of central pedestal center definition of this chair pin, when office seats bears the gravity of weight generation, because the support column of this central authorities' pedestal winding office seats, make this central authorities' pedestal extend out skew take the top as fulcrum towards this central shaft, make this central authorities' pedestal in the bottom away from the support column of office seats, because this central authorities' pedestal only is connected on the top with this assembling arm, when therefore making office seats bear weight, stress can be concentrated and cause this central authorities' pedestal to separate with assembling arm stress destruction between this central authorities' pedestal and this assembling arm, so the structural design of this chair pin is to be improved.
Because the problem of above-mentioned background technology can't effectively solve and overcome, so the applicant proposes present patent application, to solve problem point.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to: a kind of chair pin is provided, and it can be assembled in office seats, is not easy destroyed.
