Description

Ladder pedal and ladder

Technical field

The utility model is related to a kind of ladder and its pedals, particularly a kind of ladder pedal and ladder.

Background technology

Most of ladder pedal currently on the market is rectangular configuration, i.e., the shape of the effective using face of pedal is rectangle （Referring to the rectangle pedal that " 5 " are labeled as at the rectangle frame of dotted line in Fig. 3 and Fig. 4）, in this way, the ladder for being equipped with rectangle pedal exists During use, the degree of danger of climbing person can be improved；It can especially climb and the dual-purpose ladder of sitting, degree of danger Higher.It, can be with close to the pedal edge of user due to the use of person's center of gravity and the beeline of ladder center of gravity on same series Elongated with the distance of ladder center of gravity and increase, user's center of gravity and ladder centroidal distance are longer, more dangerous for user.

Utility model content

The one of the utility model is designed to provide a kind of simple and reasonable for structure, meets use demand, applied widely Ladder pedal, with overcome the deficiencies in the prior art.

What one purpose of the utility model was realized in：

A kind of ladder pedal, including pedal body, pedal body top surface is to trample face, it is characterised in that：The pedal One group of opposite side of body be respectively convex arc while and during concave arc.

One purpose of the utility model can also use following technical measures to solve：

As a kind of more specific scheme, the convex arc while and when concave arc be mutually parallel.

The convex arc while and when concave arc be arc-shaped.The design on concave arc side also helps user's sitting.

The face of trampling is equipped with anti-skid chequer.

Pedal has the beneficial effect that in the utility model：

The area and materials of such ladder pedal almost do not have compared with the area and materials of rectangle pedal in the prior art It changes, still, due at left and right sides of pedal and the mounting means of ladder is unique, and by adjusting two before and after pedal Side with its at left and right sides of position relationship after, therefore, after which is connected with ladder, in the case where not improving any cost, User's center of gravity can be caused to shorten with ladder centroidal distance, reduce the danger used.

The another object of the utility model is to provide a kind of ladder simple and reasonable for structure, safe, existing to overcome There is the deficiency of technology.

What the another object of the utility model was realized in：

A kind of ladder, the pedal body including ladder and two pieces or more, pedal body top surface are to trample face, each pedal body It is arranged in up and down on ladder, it is characterised in that：One group of opposite opposite side is respectively convex arc side and concave arc before and after the pedal body Side.Such ladder can effectively shorten distance of user's use in the process with ladder center of gravity, improve the security used.

The another object of the utility model can also use following technical measures to solve：

The convex arc while and when concave arc be arc-shaped.

The face of trampling is equipped with anti-skid chequer.

The front side of the ladder is placed with pedal body up and down, wherein, positioned at the convex arc side position of the pedal body of bottom Towards front side, concave arc side towards rear side, the convex arc sides of other pedal bodies is towards rear side, and concave arc side is towards front side.In this way Design, the planimetric area of pedal can be improved, improve the security that can sit and climb dual-purpose ladder.

The ladder is staircase, including front foot frame, handrail, rear leg and connecting rod, before each pedal body is rotatably connected on On foot stool and connecting rod, handrail is arranged on front foot frame top, and rear leg upper end is rotatably assorted with front foot frame, connecting rod and rear leg /V Cooperation.

Ladder has the beneficial effect that in the utility model：

（1）Pedal body is on the basis of original rectangle pedal in such ladder, by parallel and user pedal edge （Front and rear edges）Make equidirectional arc into, to shorten user's distance of center of gravity and ladder center of gravity in use, reduce The risk to drop in use；

（2）For such ladder compared with the ladder of rectangle pedal on existing market, use is safer, more meets using habit Used, use is more comfortable；

（3）The arc side of the pedal body of bottom is outwardly in such ladder, and the planimetric area of all pedals will It can increase, user can preferably set foot on ladder；

（4）The top pedal body of such ladder can be also used for sitting, and the design of pedal body outer end edges concave arc shape makes User is obtained to be seated more comfortably.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and embodiments.

Shown in Figure 1, a kind of ladder pedal, including pedal body 1,1 top surface of pedal body is described to step on to trample face One group of opposite side of plate body 1 is respectively convex arc at 12 and concave arc 13.

The convex arc 13 is mutually parallel at 12 and concave arc.

The convex arc 13 is arc-shaped at 12 and concave arc.

The face of trampling is equipped with anti-skid chequer 11.

With reference to shown in Fig. 2, a kind of ladder for being equipped with above-mentioned pedal body 1, the pedal sheet including ladder and two pieces or more Body 1, to trample face, each pedal body is arranged in about 1 on ladder 1 top surface of pedal body.It arranges up and down the front side of the ladder There is pedal body 1, wherein, positioned at the pedal body 1 of bottom（In Fig. 2 and 4 shown in D）12, convex arc side towards front side, Concave arc side 13 is towards rear side, other pedal bodies 1（In Fig. 2 and 4 shown in U）Convex arc side 12 towards rear side, 13 court of concave arc side To front side.

The ladder is staircase, and including front foot frame 2, handrail 21, rear leg 3 and connecting rod 4, each pedal body 1, which rotates, to be connected It is connected in front foot frame 2 and connecting rod 4, handrail 21 is arranged on 2 top of front foot frame, and 3 upper end of rear leg is rotatably assorted with front foot frame 2, even Bar 4 coordinates with 3 /V of rear leg.Rear leg 3 is equipped with bolt（It is not shown in figure）, connecting rod 4 is equipped with limiting slot 41, and connecting rod 4 is logical It crosses limiting slot 41 and the bolt /V of rear leg 3 is slidably matched.

With reference to shown in Fig. 3, O points are ladder center of gravity, when in subscriber station or taking the pedal sheet being located above in the present embodiment When on body 1, the center of gravity O1 of user is close to ladder center of gravity direction with concave arc side 13（The distance between O1 points and ladder center of gravity O points For L1）；When in subscriber station or when taking on rectangle pedal 5 in the prior art, between the center of gravity O2 of user and ladder center of gravity O points Distance is L2, it is evident that L1 is shorter than L2, i.e., safer using the ladder of the present embodiment.

With reference to shown in Fig. 4, left part is to be located at the pedal body 1 of bottom in this case（Shown in D）It is stepped on its top Plate body 1（Shown in U）Vertical projection diagram, right side in the prior art with two pieces of rectangle pedals 5 of this case correspondence position Vertical projection diagram, from two figures relatively, hence it is evident that, the projected area of this case is more than the projected area of the prior art.
