The a plurality of flexural springs of label 24 expressions, it extends between first and second side frame elements 22,23, is used for flexibly supporting chair occupant's back.
The a plurality of fixed orifices of label 51 expressions, the arm element by insert bolt of rear end plate in these fixed orifices with leaning device (not having to show) is connected described fixed orifice place.
On this backrest frame BF, as shown in Figure 1, a large-sized handrail AR can be installed on first side frame elements 22, and is just as be known in the art.This large-sized handrail AR is bigger than the size that common handrail forms, and purpose is to provide a wide zone, and the user can cosily place his or her arm thereon.For this reason, one connects supporting member 30 by means of the main wall zone 22A that can be firmly attached to first side frame elements 22 as bolt of rear end plate 32.As shown in the figure, a support holes 31 is passed the main wall zone 22A that connects the supporting member 30 and first side frame elements 22 and is formed, so that the axle AR-1 of large scale handrail AR inserts this support holes 31.In this respect, though do not show, an axle AR-1 can remain in the support holes 31 rotationally by suitable mode, can not pass it and shifts out, thereby allow handrail AR vertically to rotate around axle AR-1, and is as be known in the art such.
As shown in Figure 2, between the lower frame element 20 and first side frame elements 22, provide a stirrup element 1.In addition, one fixed orifice 35 promptly is used for upright end 1B with this stirrup element 1 and is fixed to part on first side frame elements 22, be formed on the main wall zone 22A of first side frame elements 22, and be lower than the position at aforesaid connection supporting member 30 places.Although clear demonstration, this fixed orifice 35 is screwed holes.
As Fig. 3 clearly shown in, stirrup element 1 is formed by a rigid material such as steel substantially, and is general " L " shape, it has the stock part 1A and a upright quarter butt part 1B who extends of a longitudinal extension.
According to the pattern shown in the stirrup element 1, its stock part 1A on even keel extension longitudinally, and upright quarter butt part 1B extends upward, and extend continuously with the right angle substantially from the right-hand end of this stock part 1A.
That form on aforesaid stock part 1A is a flat anchor portion 1D and a flat fixed area 1C.
As shown in the figure, the fixed area 1C both of flat anchor portion 1D peace limits in vertically extending mode with respect to the longitudinal axis of stock part 1A.Flat fixed area 1C is arranged on the position near upright quarter butt part 1B.
Label 1Dh represents a screw thread fixed orifice, and it is formed on the flat anchor portion 1D, and label 1Ch represents a screw thread fixed orifice, and it is formed on the flat fixed area 1C.
Show that as Fig. 4 is clear lower frame element 20 is formed by a rigid board material, forms a reinforced rib part 20A by suitable plastic working therein, makes its slave plate base portion 20B cave in down, and extends on the longitudinal direction of lower frame element 20.In this reinforced rib part 20A, be formed with a pair of isolated fixed orifice 20H, 20H, this aligns with two screw thread fixed orifice 1Dh, 1Ch respectively to the hole, and two screw thread fixed orifice 1Dh, 1Ch are formed in the linear bar part 1A of stirrup element 1.Although clear demonstration, each among the 20H of these holes all is screwed hole.
As what from Fig. 4, see, the stock part 1A of stirrup element 1 is connected in the reinforced rib part 20A and along this reinforced rib part 20A and connects, then, by two bolt of rear end plates being driven in respectively in two retaining thread hole 20H, stirrup element 1 is connected on the lower frame element 20 tightly and extends, thereby stock part 1A is remained on the appropriate location along reinforced rib part 20A., can see that the fixed area 1C both of flat anchor portion 1D peace contacts the plane surface (at 20A) of lower frame element 20 tightly here, this guarantees that the stock part 1A of stirrup element 1 stably is fixed and can not be around its central axis rotation.This has also just guaranteed upright quarter butt part 1B is provided with in position with respect to the inboard of the main wall part 22A of first side frame elements 22, like this, the screw thread fixed orifice 1Bh of upright quarter butt part 1B aligns with screw thread fixed orifice 35 on being formed on specific main wall part 22A.Subsequently, by bolt of rear end plate being driven in two fixed orifice 1Bh, 35 that so align, the upright quarter butt part 1B of stirrup element 1 is connected with first side frame elements 22 tightly, and the flat end of upright quarter butt part 1B then contacts the plane surface of the main wall part 22A of first side frame elements tightly.
Therefore, as shown in Figure 2, only utilize three bolt of rear end plates, whole stirrup element 1 just reliably, directly is connected between the lower frame element 20 and first side frame elements 22.
So, according to the present invention, can obtain following advantage and effect:
(i) between first side frame elements 22 of lower frame element 20 and installation large scale handrail AR, arrange that so horizontally extending stirrup element 1 is an actv., it not only provides additional opposing to the multi-load of crossing that is applied by heavy large-sized handrail AR, but also give lower frame element 20 this load transfer, and disperse this load along lower frame element 20.In this respect, lower frame element 20 is also strengthened by pressure-formed reinforced rib part 20A.Therefore, positively prevented because large-sized handrail AR imposes on the crooked and distortion of crossing the caused backrest frame BF of multi-load on the side frame elements 22.
(ii) only a stirrup element 1 just can be connected with side frame elements 22 along lower frame element 20 securely, this does not need other independent element and parts really in assembling process, and thereby has accelerated the assembling process of backrest frame BF with extremely low cost.
(iii) just the situation of handrail AR is not installed on the backrest frame BF,, can easily removes stirrup element 1 from lower frame element 20 and side frame elements 22 by unscrewing simply and separating three bolts.And when being installed to handrail AR on the backrest frame BF, stirrup element 1 can easily only be connected with side frame elements 22 at three such bolt position up and down portion frame elements 20.This means, stirrup element 1 can directly, easily be used on any traditional common backrest frame, therefore, having eliminated needs to form two independently troubles of backrest frame, one of them is used for installing the situation of handrail AR thereon, and another is used for not installing the situation of any handrail AR thereon.
