Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-slip strip technology for stairs, specifically to an anti-slip strip for stairs that combines softness and hardness. Background Technology
[0002] In daily life, stairs, as frequently used building components, often pose safety hazards due to factors such as slipperiness and wear. To reduce the risk of slipping on stair surfaces, most anti-slip strips on the market are made of a single hard or soft material. Although they have a certain anti-slip effect, hard materials are prone to wear and tear over long-term use, while soft materials suffer from insufficient strength, resulting in weak adhesion or reduced anti-slip performance. Therefore, anti-slip strips made of a single material are insufficient in terms of stress distribution, protection, and cushioning, and cannot provide comprehensive protection in actual use.
[0003] In view of the above, this application proposes a stair anti-slip strip that combines hard and soft materials. The hard material provides structural stability and wear resistance, while the soft material improves anti-slip properties and cushioning. The combination of hard and soft materials not only effectively disperses stress and prevents tearing or detachment at the joints, but also enhances foot comfort and safety, especially under conditions of high-frequency stepping or significant changes in gravity. In addition, the stair anti-slip strip that combines hard and soft materials can adapt to various environmental conditions, further improving anti-slip performance in complex scenarios such as wetness and bending, thereby greatly reducing the occurrence of accidents and ensuring people's safety.

[0007] The plastic strip includes a short strip and a long strip. The short strip and the long strip are connected in an L-shape, and an anti-collision shaft is provided at the connection point. A blocking shaft is provided on the side of the long strip close to the anti-collision shaft, and a compression shaft is provided on the side of the long strip away from the anti-collision shaft. A V-shaped groove is provided in the middle of the connection between the blocking shaft and the compression shaft.
[0008] Optionally, the steel plate assembly includes an L-shaped plate, a middle plate, a short plate, and a long plate;

Therefore, they should not be construed as limitations on this utility model.
[0028] This application proposes a combination of soft and hard anti-slip strips for stairs, as detailed below:
[0029] For reference Figure 1 This application mainly consists of a plastic strip 1 and a steel plate assembly 2 dispersed on the bottom of the plastic strip 1. The plastic strip 1 dispersed on the steel plate assembly 2 makes installation and bonding more convenient. Segmented bonding can better disperse the stress on the structure and avoid concentration in a single position, thereby reducing excessive stress concentration at the bonding point and preventing tearing or falling off.
[0030] For reference Figure 1-2 The plastic strip 1 includes a short strip 101 and a long strip 102, which are connected in an L-shape. The short strip 101 and the long strip 102 are connected to the staircase via a steel plate assembly 2. The steel plate assembly 2 includes an L-shaped plate 21, a middle plate 22, a short plate 23, and a long plate 24. The L-shaped plate 21 is located on the other side of the connection between the short strip 101 and the long strip 102, corresponding to the anti-collision shaft 11. The L-shaped plate 21 is also located at the bend of the staircase. The L-shaped plate 21 can reduce... The sharp edges at the stair bends cause friction to the device; there are two middle plates 22, which are distributed on the short strips 101 to stably connect and fix the short strips 101 to the stair; the short plates 23 are located in the middle of the connection between the L-shaped plate 21 and the long plate 24 and are set on the long strip 102. They are sequentially set on the stair for bonding, making the connection more stable; the long plate 24 is located on the side of the long strip 102 away from the L-shaped plate 21 and is used to connect and fix the end.
[0031] It should be noted that the L-shaped board 21, the middle board 22, the short board 23, and the long board 24 are all provided with adhesive material on the contact surface with the stairs to achieve the bonding effect.
[0032] For reference Figure 1-2Because the L-shaped plate 21 is set at the bend of the stairs, and the anti-collision shaft 11 is set corresponding to the L-shaped plate 21, it is equivalent to wrapping the bend of the stairs and playing a protective role. The anti-collision shaft 11 consists of a large cylinder and multiple small cylinders, with the multiple small cylinders set on both sides of the large cylinder. If a person loses their footing while climbing the stairs and bumps into the bend of the stairs, the anti-collision shaft 11 will play a protective role.
[0033] A blocking shaft 12 is provided on the side of the long strip 102 near the anti-collision shaft 11. The blocking shaft 12 is inclined downward toward the V-shaped groove 14, which can reduce the situation of the person sliding forward after stepping down the stairs.
[0034] A compression shaft 13 is provided on the side of the long strip 102 away from the anti-collision shaft 11. The compression shaft 13 is in the shape of a right triangle. The compression shaft 13 is inclined downward toward the side of the long strip 102 away from the short strip 101. The hardness of the compression shaft 13 is less than that of the plastic strip 1. When stepping on the compression shaft 13 when going downstairs, the downward compression force is only slightly different from that on the upper surface of the long strip 102, thereby reducing the cushioning force when going downstairs. The inclined setting further prevents the situation of sliding forward. In addition, an anti-slip shaft 131 is provided on the upper surface of the compression shaft 13, which further increases the anti-slip effect.
[0035] A V-groove 14 is provided in the middle of the connection between the blocking shaft 12 and the compression shaft 13. After the compression shaft 13 is compressed, it avoids the situation of backlash impacting forward. When sliding forward, it will first contact the V-groove 14. There are multiple V-grooves 14, which are evenly distributed on the strip 102. The friction further reduces the sliding situation and achieves a further anti-slip effect.
[0036] The above settings can achieve anti-slip effects in multiple ways.
[0037] In this invention, the working steps of the device are as follows:
[0038] 1. First, glue the L-shaped board 21 to the turning point of the staircase, and then glue and fix the middle board 22, the short board 23 and the long board 24 in sequence.
[0039] 2. Secondly, when going downstairs, stepping on the compression shaft 13 cushions and prevents slipping on the back of the foot. The anti-slip shaft 131 on its surface further prevents slipping. Depending on the size of the foot, the V-shaped groove 14 or the blocking shaft 12 can achieve anti-slip on the front of the foot. If the foot is small, it does not contact the blocking shaft 12 and anti-slip is achieved by friction from the blocking shaft 12. If the foot is large, it contacts the blocking shaft 12 and the oblique setting of the blocking shaft 12 creates resistance by contacting the foot surface in the opposite direction, thus achieving the anti-slip effect.
[0040] 3. Finally, when going up the stairs, the anti-collision shaft 11 can prevent collisions, and the large cylindrical part of the anti-collision shaft 11 can also reduce the chance of sliding down when going upstairs, thus providing an anti-slip effect when going up and down stairs.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
