This decorate seat adopts multiple design can effectually reduce the injury that receives when the human body falls down:
a first layer: anti-skid layer
The anti-skid layer 4 can provide the effects of skid resistance, speed alleviation, contact area increase, impact force release through compression deformation and the like; vertical angle anti-skidding teeth (90 degrees anti-skidding teeth) are arranged on the anti-skidding layer, the horizontal side walls of the upper surfaces of the anti-skidding teeth are vertically arranged, and the anti-skidding teeth are non-equidistant tooth sockets, so that the anti-skidding teeth arranged are more favorable for serving as an ascending shoe arch drop point and a descending shoe heel to go out for skid prevention, the tooth sockets with different widths can buffer the descending speed, the phenomenon that the body is suddenly braked by a shoe and is unbalanced is reduced, and the anti-skidding shoes are suitable for people with different qualities and various sole grains.
A second layer: metal spring plate and buffer strip
The angle of the inclined plane section of the spring plate 5 is very critical, and is the approaching angle and the departing angle of the shoe and the decorative seat, and the balance value between the inner angle and the outer angle of the arch of the foot, the upwarp angle of the palm of the foot, the pedal angle of the palm of the foot, the included angle between the human body falling down and the ground is comprehensively considered. The spring plate, particularly the downward fan-shaped displacement (forming a buffer angle) and the buffer strip deformation of the inclined plane section of the spring plate after being stressed can form an effective buffer effect, and the spring plate is suitable for light-weight human bodies (children); and when the impact force is larger than the designed value, the third layer of buffer action is automatically triggered and started. Such as: when the impact force formed by the falling body with the height of 110-150 cm, the total mass of 27-40 kg and the top sphere radius of 80-90 mm and the mass of 2-3.1 kg is applied, the spring plate can generate fan-shaped displacement so as to slowly release 65-80% of the applied impact force and reset in a very short time, and when the impact force exceeds the impact force formed by the conditions, the buffer action is continuously generated through the metal spring ring connected with the lower part.
And a third layer: metal spring ring
When a human body with heavier mass falls down or the impact force is larger, the upper metal spring plate can only slowly release part of the impact force and transmit the rest of the impact force to the spring ring, and the impact force is slowly released through the annular deformation of the metal spring ring. Such as: when the impact force is formed by a falling body with the height of 150-160 cm, the mass of 40-60 kg and the mass of 3.2-5 kg with the top sphere radius of 90-95 mm, 80% -90% of the impact force can be slowly released through the combined action of the deformation of the spring plate and the spring ring, and the falling body can be reset in a very short time.
The stress of a human body when the human body falls down in unbalance in the process of going up and down steps is analyzed by combining computer simulation, and the method specifically comprises the following steps: the following table is classified according to the building use objects:
static (impact step in free falling state) and dynamic (motion state of 0.5 m/s) virtual impact test simulation is carried out on A, B, C, D four types of human bodies according to the step design standard of the old public building, and the conclusion is as follows:
the maximum resultant force values of the horizontal impact steps in the free falling state are as follows:
| people of all ages | Resultant force (N) |
| 3-6 years old children | 3829 |
| 7-15 years old teenagers | 8790 |
| Adult of 16-59 years old | 14478 |
| 60-69 years old | 14650 |
The maximum resultant force values of the horizontal impact steps in the motion state are as follows:
| people of all ages | Resultant force (N) |
| 3-6 years old children | 4500 |
| 7-15 years old teenagers | 9428 |
| Age 16-59 | 15586 |
| 60-69 years old | 15800 |
According to the simulation conclusion and the impact absorption resistance of 8.1.1 in the safety helmet standard GB 2811-2007: the force transmitted to the head model did not exceed 4900N (500kgf), and it can be seen that the force to which the head of the human body collides with the step during the resting and moving processes has reached the point where the safety helmet is required to be worn for protection. The injury that the human body may receive when falling is still very big, and it is necessary to design a device for reducing the injury degree.
Adopt the utility model discloses a decorate seat installation back, computer simulation effect is as follows under the same condition:
the maximum resultant force of the human head model horizontally impacting the step in the free falling state is as follows:
| people of all ages | Resultant force (N) |
| 3-6 years old children | 200 |
| 7-15 years old teenagers | 280 |
| Age 16-59 | 294 |
| 60-69 years old | 300 |
Maximum resultant force applied to the human head model horizontally impacting the step in the motion state is as follows:
it can be seen that the impulsive force of the stationary impact of the population of each age group is in turn: the impulse of children 3-6 years old is reduced by 70%; the impulse of the adolescent of 7-15 years old is reduced by 80 percent; the impulse of the population 16-59 years old is reduced by 90%; the impulse of the aged 60-69 years old is reduced by 90%. The decoration seat has obvious buffering effect, and the buffering effect is more obvious when the quality of a person is larger and the height of the person is higher. And when the human body is in the striking under the motion state, the buffer device still can effectually slow down the size of power when colliding, and the buffering effect also remains unchanged basically, can be with the human body with step external corner effectual the weakening of injury degree after the striking.
The technical scheme provided by the utility model is introduced in detail above. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
