Embodiment:
Below in conjunction with the accompanying drawings to the design explanation for example.
As shown in Fig. 1, Fig. 3, Fig. 4, the ladder of the design includes two ladder sides 1 of square bar shape, and the cross section of ladder side 1 is in work
Font is that vertical notch 2 is all machined with its front and rear wall, is machined with the cell wall in outside on notch horizontal
Ripple 6, each stull 4 that fixing device near the ladder side upper end of office with ladder side lower end between two ladder sides causes ladder
A firm frame-shaped combination is integrally formed in son, all passes through the symmetrical device of notch 2 in two ladder sides of office left and right sides
Pedal 3;The pedal 3 includes one in its outer section(Left end in i.e. shown in Fig. 3, Fig. 4)Two symmetrical claws 7 are set
Rectangular box-like clamp 9(Under vertical view state)And clamp inner segment(Big half on the right side in i.e. shown in Fig. 3, Fig. 4)It is lower straight with it
The rectangular box-like pin mouth circle 14 that connects in succession, pin mouthfuls 13(Face under state), be spaced a distance between pin mouth circle 14 and claw 7 with
Accommodate ladder side and leave necessary up and down space to pedal, the height of pin mouthful 13 be about same as the maximum gauge of people's pin instep,
The width of pin mouthful is about same as wide two times of people's pin pin;Left side in the claw 7 rectangular frame-shaped under side view state, such as Fig. 4
Shown in View component(Top right plot), the top rugosity of position lateral means one of inframe protrudes from the roller i.e. card wheel 8 of frame hem width degree,
Card wheel can be with pivoting, and pedal is by claw position together with the notch arrangement in ladder side, and the upper-lower height of claw is not low
In 2.5 times of outer rim width dimensions for blocking other condition and claw position with acquisition appropriately of notch or so width dimensions(Including card
The rugosity size of wheel)It is slightly less than the width dimensions of notch not influence to move up and down when needed, as shown in Figure 1, Figure 3, in nothing
In the case of under external force effect or only being trampled lower pressure on pin mouthful, pedal can not acted on by the card at its claw position
Any level locations of ladder side are stopped at, are under such a state, the outer rim on the underframe side of claw 7 slightly outward-dipping can be resisted against
Turn into the acquisition of outer support point on the outside ripple 6 of notch 2 in ladder side 1 reliably to support, the card wheel 8 under the upper ledge side of claw
Turn into inner support point, the inside and outside strong point in the notch interior sidewall surface that inner side wheel face can be resisted against in ladder side the characteristics of its evagination
With its can Zuo Yong not reliably produce the left side zoomed-in view in the effect of stable pedal position, such as Fig. 1 against the card of wall
It is shown;On clamp 9 in the outer side frame edge of pin mouth circle 14 be position device one in illustrating above left side by clamp before and after
The rectangular clapboard 12 that frame side is connected, directly connection one downwards is enough compared with having for dividing plate slightly narrow L-shaped at position placed in the middle for dividing plate
The pedal 10 of elasticity, as shown in Figure 3, Figure 4, pedal 10 are provided with the wheel mouthful 15 of a rectangle in its corner part occupies, and take turns intraoral
Lateral means the roller i.e. pedal wheel 11 that a rugosity protrudes from the thickness of pedal 10, close to the one of turning on the base of pedal 10
Horizontal and slightly above pin mouth circle 14 the base of section, pedal base one section away from turning then extends to pin in upwarping shape
Side frame edge in mouth circle, as shown in the front view in the upper left corner in Fig. 4, the basic structure of the downhill race ladder of such the design has just been described
Finish.It is specific climb in use, when will on climb when, both feet are put in the pin on the pedal 3 of left and right sides mouthful 13 against outside respectively
Position, the following pedal as shown in the pedal of the lower left side in Fig. 1, in Fig. 2 is diagrammatically shown, and the pin 5 stretched in foot inlet 13 exists
One upward elasticity of pin can be given when not applying pedal force the characteristics of the slightly convex mouth circle underframe side for pin of pedal 10 to squeeze
Pressure, this elastic force can promote the upper ledge side i.e. lower edge of clamp 9 of pedal and pin mouth circle 14 pin is clamped tighten to be formed one compared with
Firm is overall to facilitate pin and pedal synchronously to move up and down, and hand steered both sides ladder side moves pedal by tape, and force follows ladder side upwards
The parallel sliding of notch 2 is moved up, and pin can apply the power of upward direction to overcome gravity, frictional force to move up pin to pedal in the process
Pedal, the card wheel 8 on claw 7 can inevitably touch the two side walls of notch but because it can be flexible during this is moved up
Positive and negative rotation without by retardance card do not allow pedal smoothly to be moved up with pin, arrived after top dead center sole and stopped
The force that continues up and switch to only be downwardly applied to trample pressure, can be found in pedal force in the zoomed-in view of left side in such as Fig. 1
In the presence of, the position of claw 7 of the outer section of clamp 9 can block the wall not inside and outside the notch 2 of ladder side 1 because of the imbalance of pedal force
On, i.e., it can produce bracketing that the ripple 6 with surface relief feature set in locking phenomenon, outside wall surface also can be more reliable firmly pin
Pedaling 3 and stopping it to glide, so both feet alternately climb rise it is mobile just reach at desired height, pedal by
To pedal force effect when first pedal 10 can be moved down so as to can undertake main pedal force, this power by pin mouth circle 14
Finally it is delivered on claw 7 to produce further through clamp 9 and reliably blocks other auto-lock function, masterpiece is trampled on the base of L-shaped pedal 10
It is then turning position, the movement of pedal wheel outwards of the i.e. pedal of vertical edge lower edge of pedal with the reaction moved down on pedal vertical edge,
Be to ladder side interior sidewall surface it is more close without touching, this point ensure that the pedal force that pin mouth circle is subject to can be effective
Claw position is delivered to without being stopped, as shown in following pedal and pedal, pedal wheel in Fig. 2;When wanting falling head
When, then the notch parallel sliding that the power for inwardly pushing interior receipts application both direction downwards with the dynamic pedal of tape follows ladder side is moved down, by
In the force of pin be downwards inwardly both direction rather than it is simple this just largely balances lower pressure only downwards,
So that the wavy surface of ladder side notch is difficult to produce interception to the claw position of pedal, slid so as to smoothly lower
It is dynamic, it is to stop inside force and only retain the pedal force being downwardly applied to sole after bottom dead center, it is now unbalanced to push
The effect of power can make to occur blocking other self-locking effect as previously described stopping pedal between the inside and outside wall of claw position and notch
Move down, such shape both feet by pin alternately move down can complete decline movement, it is, of course, also possible to select more preferable decline mode
That is downhill race, specific implementation process is so:Both feet in pin mouthful 13 slide to pin mouthful is inboard(I.e. both feet are changed by separation shape
To draw close shape), it is stepped toward the upwarping in section of the base of pedal 10, that is, allow both feet to be drawn close such as a pair of of the top pedal in Fig. 1
It is shown, also as shown in the top pedal in Fig. 2, now, it can be seen that pedal force is transferred to by being mainly applied in pin mouth circle 14
On pedal 10, this action effect is reacted in pedal wheel 11 is exactly to be brought to abutment against in the interior sidewall surface of ladder side 1 simultaneously
Claw 7 as fulcrum by clamp 9 together with outer section produces the trend of interior shifting and interior shifting, as shown in the top pedal in Fig. 2, this
When do not undertake the pin mouth circle of pedal force naturally also not to claw position transmission disequilibrium power along with foregoing interior shifting trend and interior
Move, the wavy surface that the lower edge of claw 7 would not touch ladder side notch will not produce interception, by trampling that pedal undertakes
Power be finally applied to former and later two card wheels 8 top, in notch and on the lower, one in ladder side interior sidewall surface step on
Simultaneously naturally rolling downwards produces the purpose of design that decline movement phenomenon is finally reached downhill race whereabouts, the speed of decline on web wheel 11
Can be by setting the damping units such as soft wheel surface layer to regulate and control the pedal device in setting, exemplary graph in card wheel and pedal wheel
Two pairs can meet the double facility for using, being introduced also for description up and down up and down, can also a pair of pedals of a device, can evidence
Need to handle;If being intended to interim stop both feet being allowed in the intraoral outer support sliding of pin i.e. by trampling on pedal during downhill race
It is adjusted to trample on pin mouth circle base again(I.e. both feet turn to separation shape by drawing close shape change again), the claw portion of clamp as previously described
Position can be produced in notch again blocks other locking phenomenon and stops decline and reach the purpose arbitrarily stopped.Due to both feet can be packed into
Pin on pedal it is intraoral come above and below ladder, the downhill race of laborsaving convenience safety again can also be carried out, will not occur ascending stair shakiness appearance again
The dangerous situation easily fallen, is the useful improvement of this conventional apparatus of ladder.
