Detailed description of the invention
Embodiment mono-: a kind of multifunctional ladder, can be transformed to ladder state or abdomen-building machine state, vertical support bar 1 before this multifunctional ladder comprises 2, vertical 10 and 2 transverse supporting rods 6 of support bar after 2, transverse supporting rod is to be made up of cross bar 61 and the brace 62 that is connected to cross bar rear end, the angle [alpha] forming between cross bar 61 and brace 62 is 108o, before 2, between vertical support bar, pedal I 2 and pedal II 4 are installed from the bottom up successively, the both sides front end of pedal I and pedal II respectively with 2 before vertical support bar hinged, between pedal I and pedal II, connect by 2 junction plates 3 respectively, junction plate 3 middle parts have groove 31, junction plate bottom is hinged on pedal I side, junction plate top is hinged on pedal II side, pedal II two middle side parts are connected by 2 sliding connection plate I 5 respectively with vertical supporting bar top before 2, in sliding connection plate I, have chute I 51, sliding connection plate I bottom is hinged by being positioned at bearing pin I and the pedal II of chute I, bearing pin I can slide up and down to drive pedal II to rotate its relative position of change in chute I, sliding connection plate I top by be sleeved on front connecting axle 7, be arranged on 2 before between vertical supporting bar top, vertical support bar outside before 2 transverse supporting rods are arranged on 2 by front connecting axle, before 2, the cross bar front end of vertical supporting bar top and 2 transverse supporting rods is hinged, front vertical support bar, transverse supporting rod and sliding connection plate I can be rotated around front connecting axle 7.Between the cross bar 61 of 2 transverse supporting rods, be installed with pedal III 8, vertical support bar inner side after the cross bar of 2 transverse supporting rods is arranged on 2 by rear connecting axle 14, after 2, the cross bar rear end of vertical supporting bar top and 2 transverse supporting rods is hinged, and rear vertical support bar and transverse supporting rod can rotate around rear connecting axle 14.Before 2, after vertical support bar and 2, between vertical support bar lower end, be hinged with respectively 2 telescopic spring bars 13.Described telescopic spring bar comprises that rear end is provided with the solid hopkinson bar 132 of circular bosses 133, front end has the hollow stem 134 of through hole, 135 and 2 hinged seats 131 of spring, solid hopkinson bar back segment is sleeved in hollow stem through the through hole of hollow stem, solid hopkinson bar front end and hollow stem rear end are arranged on respectively on 2 hinged seats, spring fitting in hollow stem solid hopkinson bar circular bosses and and the hinged seat that is connected of hollow stem between, the diameter of solid hopkinson bar circular bosses 133 is greater than the diameter of hollow stem through hole, to ensure that solid hopkinson bar back segment can move around and not deviate from hollow stem in hollow stem, as shown in Figure 8, 2 hinged seats of telescopic spring bar are hinged on respectively on front vertical support bar and rear vertical support bar.
After described 2, between vertical support bar 10, by 2 sliding connection plate II 12, article feeder 11 is installed, in sliding connection plate II, have chute II 121, sliding connection plate II bottom is hinged by being positioned at bearing pin II and the article feeder side of chute II, sliding connection plate II top is hinged on rear vertical support bar, after rear end, article feeder both sides is hinged on respectively 2, indulges on support bar.Bearing pin II can slide up and down to drive article feeder to rotate its relative position of change in chute II.
This multifunctional ladder is in the time of ladder state, as shown in FIG. 1 to 3, pedal I 2, pedal II 4 and pedal III 8 are all in level, bearing pin I is positioned at the lowermost end of chute I 51, the brace 62 of transverse supporting rod is positioned at rear vertical support bar inner side and is fixed on rear vertical support bar 10 by latch 9 location, article feeder 11 can be opened as required in level, also can draw in after 2 and indulge between support bar.
In the time that this multifunctional ladder need to change abdomen-building machine state into, rotate pedal I 2, pedal II 4, junction plate 3 and sliding connection plate I 5 all indulges between support bar 1 it before 2, extract latch 9, make pedal III 8 between vertical support bar 10, pass certain distance from 2 by rotation, then make brace 62 bottoms, cross bar 61 front ends and the rear vertical support bar bottom of transverse supporting rod land, i.e. distortion becomes abdomen-building machine state, as shown in Fig. 4～Fig. 6.Now the groove 31 of junction plate is positioned at the hinged place of pedal II and front vertical support bar, and the effect of groove is to make the smooth gathering of connecting rod indulge between support bar 1 before 2 on the one hand, is to play certain positioning action on the other hand.When abdomen-building machine state, article feeder 11 and sliding connection plate II 12 are drawn in after 2 and are indulged between support bar.
This multifunctional ladder is in the time of abdomen-building machine state, user is sitting in pedal III 8, the drag effect producing due to the spring of telescopic spring bar 13, user need to firmly push pedal I 2 and pedal II 4 by back, just can make front vertical support bar recede, so that the solid hopkinson bar dead spring of telescopic spring bar, now spring is in contraction state, telescopic spring bar shortens, as shown in Figure 7, user stops after the application of force, due to the effect of telescopic spring bar medi-spring, produce active force and promote solid hopkinson bar, telescopic spring bar is vertical support bar reset before extending and promoting, motion and so forth, reach strong abdomen effect.
As the one conversion of the present embodiment, in the time not needing article storing function, article feeder also can be set, do not affect the present invention and realize the function of ladder and abdomen-building machine.Described telescopic spring bar also can adopt other structures, as long as have Telescopic, can produce again certain resistance and return action power.The angle [alpha] forming between the cross bar of described transverse supporting rod and brace can also be done suitable adjustment according to actual conditions, is generally 105～110o.
Before the present invention, vertical support bar, junction plate, sliding connection plate I, rear vertical support bar and sliding connection plate II can adopt stainless steel pipe, aluminium extruded sections or timber to make, 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 large multi-part of the present invention can adopt bolt to realize, and also can adopt other can realize hinged part and realize.
