Detailed description of the invention:

Explanation for example to the design below in conjunction with the accompanying drawings.

As shown in Fig. 1, Fig. 3, Fig. 4, the ladder of the design comprises two ladder sides 1 of square bar shape, the cross section of ladder side 1 is I-shaped to be i.e. all machined with vertical notch 2 on wall before and after it, it is machined with horizontal ripple 6 on the cell wall being in outside on notch, between two ladder sides, fixing device near ladder side upper end, office and each stull 4 of ladder side lower end makes ladder that a firm frame-shaped combination is integrally formed, and all passes through that notch 2 is symmetrical installs pedal 3 in two ladder sides of office left and right sides；Described pedal 3 comprises one under the rectangular box-like clamp 9(vertical view state that its outer section (left end in i.e. shown in Fig. 3, Fig. 4) arranges two symmetrical claws 7) and clamp inner segment (the big half on the right side in i.e. shown in Fig. 3, Fig. 4) under the rectangular box-like foot mouth circle 14 that directly connects, foot mouth 13(face under state), it is spaced a distance to accommodate ladder side between foot mouth circle 14 and claw 7 and leaves the up and down space of necessity to pedal, the height of foot mouth 13 is about same as the maximum gauge of people's foot instep, the width of foot mouth is about same as that people's foot foot is wide two times；nullDescribed claw 7 rectangular frame-shaped under side-looking state，As shown in the left side view part in Fig. 4 (top right plot)，Position lateral means one rugosity top in frame protrudes from the roller of frame hem width degree and i.e. blocks wheel 8，Card wheel can be with pivoting，Pedal passes through claw position together with the notch arrangement in ladder side，The upper-lower height of claw is not less than 2.5 times of notch left and right width dimensions and is slightly less than the width dimensions of notch and moves up and down not affect obtaining the appropriate outer rim width dimensions (the rugosity size of bag card expanding wheel) blocking other condition and claw position，Such as Fig. 1、Shown in Fig. 3，In the case of only being trampled downforce under without External Force Acting or on foot mouth，Pedal can not act on, by the card at its claw position, any level locations stopping at ladder side，It is under this kind of state，The outer rim on the underframe limit of claw 7 can the most outward-dipping be resisted against on the outside wavy surface 6 of the notch 2 in ladder side 1 becomes outer support point acquisition support reliably，Inner support point is become in the notch interior sidewall surface that the inner side wheel face of the card wheel 8 under the upper ledge limit of claw can be resisted against in ladder side because of the feature of its evagination，The inside and outside strong point with its do not act on the effect of stable pedal position of producing reliably against the card of wall，As shown in the left side zoomed-in view in Fig. 1；On clamp 9 be in during the outer side frame edge of foot mouth circle 14 i.e. illustrates position device above left side one by clamp before and after the rectangular clapboard 12 that is connected of frame limit, dividing plate has sufficiently resilient pedal 10 what position straight placed in the middle connected downwards a L-shaped the narrowest compared with dividing plate, such as Fig. 3, shown in Fig. 4, pedal 10 has the wheel mouth 15 of a rectangle in its corner part occupies, in wheel mouth, also lateral means a rugosity and is protruded from the roller i.e. pedal wheel 11 of pedal 10 thickness, near one section of horizontal and slightly above foot mouth circle 14 base at turning on the base of pedal 10, pedal base then extends to side frame edge in foot mouth circle in upwarping shape away from one section of turning, as shown in the front view in the upper left corner in Fig. 4, so basic structure of the downhill race ladder of the design is just described.nullDuring concrete climbing uses，When will on climb time，Both feet put in the interior position against outside of foot mouth 13 on the pedal 3 of left and right sides respectively，Pedal such as the lower left side in Fig. 1 illustrates、Following pedal in Fig. 2 is diagrammatically shown，Stretching the summary epirelief of pedal 10 when not applying pedal force of the foot 5 in foot inlet 13 can give foot one resilient pressing force upwards for the feature on foot mouth circle underframe limit，This elastic force can promote the upper ledge limit i.e. lower edge of clamp 9 of pedal and foot mouth circle 14 foot clamping to be tightened one more firm entirety of formation to facilitate foot and pedal Tong Bu to move up and down，Hand steered both sides ladder side by tape move pedal upwards exert a force follow in notch 2 parallel sliding of ladder side move，Foot can apply the power of upward direction to overcome gravity to pedal in the process、Pedal is moved in frictional force，Blocking on claw 7 can inevitably touch the two side walls of notch but because it the most positive and negative rotation can not make pedal to move with on foot smoothly without being blocked by retardance during wheel 8 moves on this，Arrive after top dead center sole to stopped the force continued up and transfer to and be only downwardly applied to trample pressure，As Fig. 1 can find under the effect of pedal force in the zoomed-in view of left side，Claw 7 position of the outer section of clamp 9 can be blocked because of the imbalance of pedal force not on the inside and outside wall of the notch 2 of ladder side 1，I.e. can produce locking phenomenon，The ripple 6 with surface relief feature arranged in outside wall surface also can be more reliable bracketing firmly pedal 3 make it stop will not to glide，So both feet are alternately climbed and are risen mobile just can arrival at desired height，First pedal can be made when acting on by pedal force pedal 10 move down thus can be by foot mouth circle 14 to undertake main pedal force，This power finally is delivered on claw 7 produce further through clamp 9 blocks other auto-lock function reliably，The base of L-shaped pedal 10 is moved down, by pedal force effect, the position, turning that the reaction on pedal vertical edge is then the i.e. pedal of vertical edge lower edge of pedal、The movement that pedal wheel is outside，It is i.e. more close and do not touch to the interior sidewall surface of ladder side，This point ensure that the pedal force that foot mouth circle is subject to can effectively be delivered to claw position without being stopped，Such as the following pedal in Fig. 2 and pedal、Shown in pedal wheel；nullWhen wanting falling head，Then move the pedal notch parallel sliding that the interior power receiving applying both direction of pressure follows ladder side down downwards by tape to move down，Due to the force of foot be downwards inwardly both direction rather than simple downwards，This balances downforce the most to a great extent，The wavy surface making ladder side notch is difficult to the claw position to pedal and produces interception，The movement such that it is able to glide smoothly，I.e. stop inside force to sole after bottom dead center and only retain the pedal force that is downwardly applied to，The effect of the most unbalanced downforce can make to occur between the inside and outside wall of claw position and notch foregoing to block other self-locking effect thus stop moving down of pedal，So both feet of shape alternately move down by foot i.e. can complete to decline and move，Certainly，Can be to select preferably to decline mode i.e. downhill race，Concrete implementation process is so: the both feet in foot mouth 13 are to the inboard sliding of foot mouth (i.e. both feet are changed to draw close shape by separating shape)，It is made to step toward in the section of upwarping on the base of pedal 10，Both feet are i.e. allowed to draw close as shown in the pedal of a pair, the top in Fig. 1，Also as shown in the top pedal in Fig. 2，Now can find，Pedal force has been transferred on pedal 10 by being mainly applied on foot mouth circle 14，This action effect is reacted on pedal wheel 11 be brought to abutment against exactly in the interior sidewall surface of ladder side 1 and as fulcrum, together with the claw 7 of outer section, clamp 9 produced the trend of interior shifting and interior shifting，As shown in the top pedal in Fig. 2，The foot mouth circle the most not undertaking pedal force does not adds aforesaid interior shifting trend and interior shifting to claw position transmission disequilibrium power，The lower edge of claw 7 would not touch the wavy surface of ladder side notch will not produce interception，The pedal force undertaken by pedal is finally applied to top、Two card wheels 8 and on the lower before and after being in notch、It is on a pedal wheel 11 of ladder side interior sidewall surface and rolling downwards produces the mobile phenomenon of decline and is finally reached the purpose of design that downhill race is fallen，The speed declined can regulate and control setting by arranging the soft damping units such as surface layer of taking turns on card is taken turns and pedal is taken turns，Pedal device in exemplary graph upper and lower two double uses up and down to meeting，Also for describing the facility introduced，Can also a pair pedal of a device，Can process according to needs；Such as being intended to during downhill race stop temporarily, both feet can be allowed to support sliding inside and outside foot mouth and be i.e. adjusted to and trample on foot Kou Quan base (i.e. both feet are changed to separate shape by drawing close shape again) by trampling on pedal again, the claw position of clamp can produce in notch again and block other locking phenomenon and stop the purpose that decline reaches arbitrarily to stop as previously mentioned.Owing to carrying out upper and lower ladder in both feet can be packed into the foot mouth on pedal, it is also possible to carry out the downhill race of laborsaving convenience safety again, the dangerous situation that ascending stair shakiness is easily fallen will not occur again, be the useful improvement of this conventional apparatus of ladder.
