Embodiment 1

[0038] Example 1: Combination figure 1 , 2 , It is fixedly installed on the two feet of the ordinary staircase [1] on the side against the wall, respectively, the position adjustment card slot [2] with the position adjustment round pin [8], and the position adjustment card slot [2] is processed with multiple Crescent-shaped adjustment bayonet [16], install a stop rod [11] on the outside of the crescent-shaped adjustment bayonet [16], between the stop rod [11] and the outer stop rod [12] of the position adjustment slot [2] Install the compression spring [10] in between so that the stop rod [11] is always close to the outside of the crescent adjustment bayonet [16] to prevent the position adjustment round pin [8] from slipping out of the crescent adjustment bayonet [16], and the position adjustment slot [2] Fix it on the foot of the stairs with screws or nails through the mounting holes [13] and make the opening of the crescent adjustment bayonet [16] downward to form a stepped ad...

Embodiment 2

[0042] Example 2: Combination image 3 , It is to fix and install the position adjustment slot [2] with the position adjustment round pin [8] described in Example 1 on the two columns of the ordinary staircase [1] on the side against the wall, and adjust the crescent shape The opening of the bayonet [16] is upward to form a step-wise adjustment mechanism for the angle between the elastic steel sheet [18] and the ground; the two feet of the ordinary staircase [1] are fixed on the side against the wall with a fixing seat [20] Round pin [9]; elastic steel sheet [18] (elastic steel sheet [18] can also be replaced by a whole strip of metal, wood, bamboo material with appropriate strength) one end is connected to the position adjustment round pin [8], and the other end is installed with anti-skid The pad [6] is in contact with the ground to increase the coefficient of friction between the elastic steel sheet [7] and the ground; connect one end of the connecting rod [19] to the round p...

Embodiment 3

[0046] Example 3: Combination Figure 7 , It is based on the foregoing embodiment, an inclined support plate [37] is installed under the two feet of the staircase [1] and connected to the support rod [3] through a connecting rod [36] and can be rotated. The inclined support plate [ The angle of 37] should be equal to or slightly smaller than the angle of the stairs. When using stairs, place the feet of the stairs [1] on the inclined plane support plate [37]. When a person climbs up the stairs, the downward movement distance of the stairs is reduced to a certain extent, and the stairs can only follow the inclined plane. The slope of the support plate [37] slides down to prevent vertical downward movement, keeping the overall angle of the stairs unchanged, so that the upper end of the stairs can always be in contact with the wall, improving the stability of the stairs, and preventing the foot of the stairs from moving down vertically when people climb the stairs The upper end of ...

Abstract

The invention discloses a support-increasing pressurizing anti-skidding stair. According to the support-increasing pressurizing anti-skidding stair, the number of supporting rods between a common stair and a wall is increased, angles between increased supporting rods and the ground are adjusted through proper methods and are maintained to be stable so that the increased supporting rods are enabled to be closely attached to the ground and bear certain gravity, angles of acute angles of action force of the stair on the ground are increased, positive pressure and sliding friction resistance received by the ground are increased, and outward horizontal sub-force is reduced, especially when the stair has tendency of sliding outward or sliding a certain distance, acute angles between force arms of the increased rod and the ground are increased, and feet of the stair are lifted so that direction action force of the stair foot on the ground is reduced and even the feet of the stair are enabled to leave the ground, and therefore the action force of the stair on the ground is mainly or fully borne by the increased supporting rods, angles of acute angles of integrated action force of the stair on the ground and the positive pressure are enabled to be larger, the horizontal sub-force is enabled to be smaller and stop the stair from sliding. The support-increasing pressurizing anti-skidding stair solves the problems that an existing stair can slide easily and cause potential safety hazards. The support-increasing pressurizing anti-skidding stair is simple in structure, convenient to use, and can be achieved as long as supporting rods are added on the existing stair.

Description

Technical field [0001] The invention relates to an anti-skid staircase, in particular to a support rod or frame added on the inner side of an ordinary staircase to increase the positive pressure of the staircase on the ground and reduce the horizontal outward component force to realize the anti-slip function. technical background [0002] Ordinary stairs, in order to climb the stairs comfortably, need to make the acute angle between the stairs and the ground small, resulting in a large outward horizontal force, especially when people climb to a higher position, the force of the stairs on the wall increases The positive pressure on the ground becomes smaller, and the frictional force is easily smaller than the outward horizontal component. Especially on the smooth cement and tile floors, ordinary stairs are easy to slide and cause safety accidents. In addition, the living standards in recent years In the vast majority of rural households, the ground is basically hardened, and acci...
