The specific embodiment
Embodiment one: a kind of multifunctional ladder; Can be transformed to ladder state or abdomen-building machine state; Vertical support bar 10 and 2 transverse supporting rods 6 behind 1,2 of the vertical support bars before this multifunctional ladder comprises 2, transverse supporting rod is to be made up of cross bar 61 and the brace 62 that is connected the cross bar rear end, the angle [alpha] that forms between cross bar 61 and the brace 62 is 108o; Between the vertical support bar pedal I 2 and pedal II 4 are installed successively from the bottom up before 2; The both sides front end of pedal I and pedal II respectively with 2 before vertical support bar hinged, connect through 2 junction plates 3 respectively between pedal I and the pedal II, junction plate 3 middle parts have groove 31; The junction plate bottom is hinged on the pedal I side; The junction plate top is hinged on the pedal II side, pedal II two middle side parts with 2 before vertical supporting bar top be connected through 2 sliding connection plate I 5 respectively, have chute I 51 on the sliding connection plate I; Sliding connection plate I bottom is hinged through the bearing pin I and the pedal II that are positioned at the chute I; The bearing pin I can slide up and down in the chute I to drive the pedal II and rotate its relative position of change, and indulge between the supporting bar top through before being installed in 2 on the connecting axle 7 before being sleeved on sliding connection plate I top, the vertical support bar outside before 2 transverse supporting rods are installed in 2 through preceding connecting axle; The cross bar front end of vertical supporting bar top and 2 transverse supporting rods is hinged before 2, and preceding vertical support bar, transverse supporting rod and sliding connection plate I can be rotated around preceding connecting axle 7.Be installed with pedal III 8 between the cross bar 61 of 2 transverse supporting rods; Vertical support bar was inboard after the cross bar of 2 transverse supporting rods was installed in 2 through back connecting axle 14; The cross bar rear end of vertical supporting bar top and 2 transverse supporting rods is hinged after 2, and vertical support bar in back and transverse supporting rod can rotate by connecting axle 14 around the back.Be hinged with 2 telescopic spring bars 13 respectively between the vertical support bar lower end behind vertical support bar and 2 before 2.Described telescopic spring bar comprises that the rear end is provided with hollow stem 134, spring 135 and 2 hinged seats 131 that the solid hopkinson bar 132 of boss platform 133, front end have through hole; The through hole that the solid hopkinson bar back segment passes hollow stem is sleeved in the hollow stem; Solid hopkinson bar front end and hollow stem rear end are installed in respectively on 2 hinged seats; Spring be installed in the hollow stem solid hopkinson bar boss platform and with hinged seat that hollow stem is connected between; The diameter of solid hopkinson bar boss platform 133 is greater than the diameter of hollow stem through hole, can in hollow stem, move around and do not deviate from hollow stem to guarantee the solid hopkinson bar back segment, and is as shown in Figure 8; Vertical support bar was indulged on the support bar with the back before 2 hinged seats of telescopic spring bar were hinged on respectively.
Through 2 sliding connection plate II 12 article feeder 11 is installed between the vertical support bar 10 after described 2; Have chute II 121 on the sliding connection plate II; Sliding connection plate II bottom is hinged through the bearing pin II and the article feeder side that are positioned at the chute II; Sliding connection plate II top is hinged on the vertical support bar in back, indulges on the support bar after rear end, article feeder both sides is hinged on 2 respectively.The bearing pin II can slide up and down in the chute II to drive the article feeder and rotate its relative position of change.
When this multifunctional ladder is in the ladder state; Like Fig. 1～shown in Figure 3; Pedal I 2, pedal II 4 and pedal III 8 all are in level, and the bearing pin I is positioned at the lowermost end of chute I 51, and the brace 62 of transverse supporting rod is positioned at inboard latch 9 positioning and fixing of also passing through of the vertical support bar in back on the vertical support bar 10 in back; Article feeder 11 can be opened as required and be in level, also can draw in and indulge between the support bar after 2.
When this multifunctional ladder need change the abdomen-building machine state into; Rotating pedal I 2, pedal II 4, junction plate 3 and sliding connection plate I 5 makes it all before 2, indulge between the support bar 1; Extract latch 9, make pedal III 8 pass certain distance between the vertical support bar 10 after 2, the vertical support bar bottom in brace 62 bottoms, cross bar 61 front ends and back of transverse supporting rod is landed through rotation; I.e. distortion becomes the abdomen-building machine state, like Fig. 4～shown in Figure 6.The groove 31 of junction plate is positioned at the hinged place of pedal II and preceding vertical support bar at this moment, and the effect of groove is that the smooth gathering of connecting rod is indulged between the support bar 1 before 2 on the one hand, is to play certain positioning action on the other hand.During the abdomen-building machine state, article feeder 11 and sliding connection plate II 12 are drawn in and are being indulged between the support bar after 2.
When this multifunctional ladder was in the abdomen-building machine state, the user was sitting on the pedal III 8, because the drag effect that the spring of telescopic spring bar 13 produces; The user need firmly push pedal I 2 and pedal II 4 through the back, and vertical support bar recedes before just making, so that the solid hopkinson bar dead spring of telescopic spring bar; This moment, spring was in contraction state, and the telescopic spring bar shortens, and is as shown in Figure 7; After the user stops the application of force, because the effect of telescopic spring bar medi-spring produces active force and promotes solid hopkinson bar; Vertical support bar resetted before the elongation of telescopic spring bar promoted, and so moved back and forth, and reached strong abdomen effect.
As a kind of conversion of present embodiment, when not needing the article storing function, also the article feeder can be set, do not influence the function that the present invention realizes ladder and abdomen-building machine.Described telescopic spring bar also can adopt other structures, as long as have Telescopic, can produce certain resistance again and return action power gets final product.The angle [alpha] that forms between the cross bar of described transverse supporting rod and the brace can also be done suitable adjustment according to actual conditions, is generally 105～110o.
Vertical support bar, junction plate, sliding connection plate I, the vertical support bar in back and sliding connection plate II can adopt stainless steel pipe, aluminium extruded sections or timber to make before the present invention, and pedal I, pedal II, pedal III and article feeder can adopt corrosion resistant plate, aluminium template or plank to make.
Articulated manner between the big multi-part of the present invention can adopt bolt to realize, also can adopt other can realize hinged part realization.
