Below, be illustrated for first embodiment that the present invention is specialized according to accompanying drawing.Folding door shown in Figure 1 is, door-plate 1a～1d can and be located at guide rail 12a, 12b (with reference to Fig. 4) pulling of bottom, bottom surface along guide rail 11a, the 11b (with reference to Fig. 7) that are located at end face top, and can carry out different operations and support.
That is to say that door- plate 1a, 1b, the central portion of its rising wood width prop up by top leading block 13a, 13b and be held in upper rall 11a place, the central portion of lower edge width props up by bottom leading block 14a, 14b and is held in lower guide 12a place.
Equally, door-plate 1c, 1d, the central portion of its rising wood width prop up by top leading block 13c, 13d and are held in upper rall 11b place, and the central portion of lower edge width props up by bottom leading block 14c, 14d and is held in lower guide 12b place.
In above-mentioned each door-plate 1a～1d, set bottom leading block 14a～14d and support bigger load than top leading block 13a～13d.
Door- plate 1a, 1b can rotate binding by hinge 15a, and door-plate 1c, 1d can rotate binding by hinge 15b.Therefore, when door- plate 1a, 1b and door-plate 1c, 1d rotate mutually, door-plate 1a～1d just can fold and enter upper rall 11a, 11b one side.
The structure of bottom leading block 14a～14d is illustrated with that.Because bottom leading block 14a～14d has identical structure, therefore a structure to bottom leading block 14a is illustrated.
As Fig. 2 and shown in Figure 4, on the leading block main body 16 of bottom leading block 14a, can rotate and support 4 wheels 17.For wheel 17 can be rotated on the bottom surface of lower guide 12a, leading block main body 16 is inserted and is led in lower guide 12a.
The top of wheel 17 extends the top 18 of lower guide 12a by only gap.Therefore, wheel 17 is to be supported with irremovable state up and down basically in lower guide 12a.
At the central portion of leading block main body 16, stood vertically metal first fulcrum 19, the lower end of this first fulcrum 19 is fixed on the leading block main body 16.In addition, first fulcrum 19 is inserted the tube portion 21 of leading in first retaining member 20, and the both sides of this first retaining member 20 are fixed on the lower frame of door-plate 1a with screw 22.
The upper end of first fulcrum 19 is formed with the anticreep spare 23 of flange-like, to prevent coming off to tube portion 21 tops.Hexagonal rod portion 24 is formed at the top of first fulcrum 19, and tube portion 21 is by forming synthetic resin.Then, as shown in Figure 3, hexagonal top, the cross section of hexagonal rod portion 24 is entrenched on the inner peripheral surface of a portion 21.Such hexagonal rod portion 24 and tube portion 21 have constituted the slip resistance generating unit.
Therefore, first fulcrum 19, can be supported at above-below direction under the state of the slip resistance that invests regulation with respect to tube portion 21 with relatively moving.The setting value of this slip resistance is the value that first fulcrum 19 does not relatively move for tube portion 21 under the static load of door-plate 1a.Therefore, the effect of this slip resistance generating unit is as the holding device that keeps door-plate 1a static load.
Below the hexagonal rod portion 24 of first fulcrum 19, be formed with spiral axial region 25, be combined with nut 26 on this spiral axial region 25.And first retaining member 20 is supported on this nut 26.
Therefore, constituted the lower position setting device of door-plate 1a～1d by first retaining member 20, spiral axial region 25 and nut 26.In addition, as shown in Figure 5, if nut 26 is moved to the below of spiral axial region 25, tube portion 21 increases for the scope that first fulcrum 19 can relatively move, and simultaneously, the lower position of door-plate 1a～1d is set in the below.
Below, be illustrated with regard to the structure of top leading block 13a～13d.Top leading block 13a～13d is a same structure, so a structure to top leading block 13a is illustrated.
As shown in Figures 7 and 8, on the leading block main body 27 of top leading block 13a, 4 wheels 28 are being supported with the state that can rotate, and this wheel 28 is in up and down immotile state basically and rotates in upper rall 11a.
Be fixed with the upper end of second fulcrum 29 on leading block main body 27, this second fulcrum 29 is inserted and is led in second retaining member 30, and this second retaining member 30 is fixed in the upper ledge of door-plate 1a by screw 31.
Be formed with flange portion 32 in the lower end of second fulcrum 29, between this flange portion 32 and second retaining member 30, be equipped with helical spring 33.Therefore, be on the door-plate 1a at second retaining member 30, because helical spring 33 can act on flexible Hui Li upward always.In addition, second retaining member 30 relies on the reaction force of the elasticity Hui Li of helical spring 33 for second fulcrum 29, and it can be relatively moved on above-below direction.
Below, the action of the folding door of structure is illustrated for having as above.Door-plate 1a～1d is moved along upper rall 11a, 11b, and when the end limit of door-plate 1a, 1d was contacted with wall surface, as shown in Figure 1, door-plate 1a～1d was in full closing state.
