Description

Step trim with cushioning, power assist and knee protection

Technical Field

The invention discloses a novel step decoration seat, in particular to a step decoration seat with buffering, power-assisting and knee-protecting functions.

Background technique

The steps of buildings such as schools, theaters, railway stations, overpasses, and underground passage entrances and exits all have certain safety hazards. For example, the outer corners of the steps are in a linear shear shape (Figure 1). If a pedestrian loses balance and falls to the ground, the back of the head, back, and elbow joints are extremely susceptible to serious injuries after the body collides with the outer corner.

However, the step protection products currently sold in the market are mainly aimed at preventing slippage and are preventive rather than impulse-eliminating products.

In order to solve the above problems, the present invention intends to develop a step decoration seat with buffering function, power-assisting function and knee protection function, which has more practical application value.

Summary of the invention

The purpose of the present invention is to address the deficiencies in the prior art and provide a step decorative seat with buffering, power-assisting and knee-protecting functions. The main purpose is to improve the linear shear band area on the surface of the step into a surface buffer layer through the step decorative seat, which has buffering, power-assisting and knee-protecting functions.

The step decorative seat with buffering, power-assisting and knee protection functions of the present invention comprises an anti-slip rubber layer, an alloy support plate component group, an alloy base plate and a plurality of alloy leaf springs. The alloy base plate is fixed to the surface of the step. The alloy support plate component group comprises two alloy support plates of different sizes arranged on both sides of the alloy base plate. The upper edges of the two alloy support plates are fixed to the alloy base plate through spring components. The two alloy support plates and the alloy base plate completely cover the step surface to form a roof shape as a whole. The protective rubber layer is arranged on the surface of the entire roof-shaped structure and covers the edge of the step. A plurality of alloy leaf springs for supporting the support plates are arranged between each alloy support plate and the step surface.

In the above technical solution, one of the two alloy support plates close to the outer edge of the step has an ergonomic contour, and its shape imitates the outer contour of the human skull or knee.

The lower edge of one of the two alloy supporting plates close to the outer edge of the step is fixed to the outer side surface of the step, so that the edge of the step is covered under the supporting plate.

The anti-skid rubber layer is provided with a hexagonal omnidirectional anti-skid structure. The anti-skid rubber layer can adopt a hexagonal omnidirectional anti-skid design, that is, the anti-skid units in the hexagonal omnidirectional anti-skid structure are regular hexagons, and each anti-skid unit shares a side with six adjacent anti-skid units to form a honeycomb shape.

The alloy substrate is fixed on the step surface at a distance of 1/4 to 1/2 of the step width from the step edge. The angle between the two alloy support plates and the step surface does not exceed 30°.

The step decorative seat of the present invention utilizes a special structural design to change the original linear shear band area on the step surface into an overall planar buffer layer, and can conform to the ergonomic contour, reduce hard injuries during accidental falls, and can use the inclined surface to provide angle support and use the gravity rebound performance to provide upward assistance for pedestrians. In addition, the deformation performance of the alloy can be used to reduce the gravity impact on the leg joints when descending.

Detailed ways

The present invention will be further described and illustrated below in conjunction with the accompanying drawings.

As shown in Figs. 2 and 3, the step decorative seat with buffering, power-assisting and knee-protecting functions of the present invention comprises an anti-slip rubber layer 1-1, an alloy substrate 1-3, an alloy leaf spring 1-2 and an alloy support plate component group 1-4. The alloy substrate is fixed on the step surface. The alloy support plate component group comprises two alloy support plates which are arranged on both sides of the alloy substrate. The upper edges of the two alloy support plates are fixed to the alloy substrate through spring components. The support plates and the alloy substrate completely cover the step surface to form a roof shape as a whole. The protective rubber layer is fixedly spread on the entire roof-shaped structure surface. A number of high-performance alloy leaf springs for supporting the support plates are arranged between each support plate and the step surface.

The anti-slip rubber layer, the supporting plate component group, the base plate and the alloy leaf spring in the step decorative seat constitute the buffer system of the entire decorative seat:

The anti-skid rubber layer is used to prevent displacement and can form a first wave buffer surface. The rubber layer can be provided with a hexagonal omnidirectional anti-skid structure (as shown in FIG. 4 ), and a honeycomb omnidirectional anti-skid buffer layer is formed by regular hexagonal anti-skid units.

The lower edge of the one of the two support plates close to the step edge is fixed to the outer side of the step, and the step edge is covered under the base plate. The support plate can be ergonomically designed, and its shape imitates the outer contour of the human skull or knee (as shown in Figure 5). When an accident occurs, the alloy support plate can ensure the maximum area of force dispersion, and the high-performance alloy leaf spring under the support plate can provide a second wave of buffering to weaken the impact. At the same time, combined with the support plate design that conforms to the ergonomic contour, it can minimize the hard damage to the human body.

In addition, the alloy substrate can be fixed on the step surface at a distance of 1/4-1/2 of the step width from the step edge. It is particularly preferred to be set at the 1/4-1/3 position. The angle between the two support plates and the step surface is preferably no more than 30°, usually a few degrees or more than ten degrees, to ensure the comfort of pedestrians going up and down the steps. The shape of the step decorative seat can form an angle support, which works together with the anti-slip rubber layer to increase the upward force and downward resistance (Figure 6). When a person is walking, the inclination of the alloy support plate combined with the high-performance alloy leaf spring inside, while providing a buffering effect, the plate surface will bear the gravity of the person and the friction during the walking process. The combined reaction force can provide a certain amount of assistance to the human body.

The step decorative seat of the present invention is different from the preventive step protection products on the existing market. The decorative seat can eliminate impulse, provide assistance and resistance, and protect the human knees. It can be widely used in schools and public areas with large passenger flow (cinemas, gymnasiums, subways, etc.) to reduce accidents when going up and down stairs. If an accident occurs, it can minimize human injuries.
