Antiskid stair step

Abstract

The utility model relates to a stair step, in particular to an anti-skidding stair step. The step is composed of an anti-skid plate, metal screws and side plates, the metal screws are evenly distributed on the anti-skid plate, and drainage holes are formed in the portions, between the metal screws, of the anti-skid plate. Side plates are arranged on the two sides of the anti-skid plate respectively. The step can effectively enhance the anti-skidding capability through the metal screws, so that the stair step is not easy to slip; the shoe sole and the anti-skid plate can be separated through the metal screws during treading, it is guaranteed that snow or ice is not prone to covering, and the anti-skid capacity is kept. Water can be drained through the drainage holes, the surface of the step is not prone to icing, accumulated snow can be accumulated, and therefore it can be further guaranteed that the step is not prone to being covered, and the anti-skid capacity of the step is further kept. Falling damage caused by slipping when people go up and down stairs can be effectively reduced. The problems that an existing stair step is prone to covering, and consequently the anti-skid capacity is lost easily are solved.

Description

Technical Field

[0001] The utility model relates to a stair step, in particular to a non-slip stair step. Background Art

[0002] Since the connection and disconnection of drill pipes need to be carried out above the wellhead, an oil drilling platform (or workover rig) for installing drilling equipment or workover equipment is generally erected high above the ground. When going up and down the oil drilling platform, it is generally through stairs. Since the oil drilling platform is used outdoors, in winter, especially when going up and down the stairs of the oil drilling platform after snowing, it is easy to slip on the stair steps, which may easily lead to falls.

[0003] The patent application with the publication number of CN221546157U discloses a round floating-point rubber and plastic stair step, which includes a non-slip layer on the upper layer of the step, non-slip dots on the step, non-slip vertical strips on the step, a round edge of the step, a buffer layer of the step, a non-slip bonding layer of the step, a bottom bonding strip, a bottom storage space, a fixing strip, and a magic tape. By increasing the non-slip dots and non-slip vertical strips, the anti-slip property and three-dimensional sense of the step are increased, and the overall aesthetic degree is increased. At the same time, a three-layer structure is set, and a step buffer layer is arranged in the middle, which can increase the buffer degree of the component and its comfort. A bottom storage space is arranged at the bottom, and some small objects can be placed in it. There are also fixing strips and magic tapes, which are stably fixed inside the storage space. It can hold some small objects that are easy to lose and prevent others from finding them.

[0004] The above-mentioned stair step enhances the anti-slip ability by increasing the non-slip dots and non-slip vertical strips on the step. However, snow is likely to accumulate on the stair step and cover the non-slip dots and non-slip vertical strips, or when the surface of the step freezes and covers the non-slip dots and non-slip vertical strips, it is easy to cause it to lose the anti-slip ability. Therefore, it is necessary to design a non-slip stair step for easy renovation. Summary of the Invention

[0005] The purpose of the utility model is to provide a non-slip stair step that is not easily covered and can effectively maintain the anti-slip ability, so as to solve the problem that the existing stair steps are easily covered and then easily lose the anti-slip ability.

[0006] The technical solution of the utility model is as follows:

[0007] A non-slip stair step is composed of a non-slip plate, metal screws, and side plates. It is characterized in that metal screws are evenly distributed on the non-slip plate, and drain holes are arranged on the non-slip plate between the metal screws; side plates are respectively arranged on both sides of the non-slip plate.

[0008] The side plates are in an inverted "convex" shape, and limiting claws are arranged on the inner side of the bottom end of the side plates.

[0009] A non-slip stair tread is composed of a non-slip plate, metal screws, and fasteners, characterized in that: metal screws are evenly distributed on the non-slip plate, and drainage holes are provided on the non-slip plate between the metal screws; fasteners are respectively provided at both ends of the non-slip plate.

[0010] The fastener consists of an upper clamping plate, a lower clamping plate, a clamping bolt, a pressure plate, and a tightening bolt. The upper and lower clamping plates are spaced apart, and the upper clamping plate is connected to the lower clamping plate by the clamping bolt. A pressure plate is provided below the end of the upper clamping plate inside the clamping bolt, and the pressure plate is connected to the upper clamping plate by the tightening bolt. The pressure plate is abutted against the anti-slip plate.

[0011] The bottom of the pressure plate is provided with a claw, which is inserted into the drainage hole at the end of the anti-slip plate.

[0012] The upper and lower clamping plates are each evenly distributed with strip-shaped holes, which are connected to clamping bolts.

[0013] The beneficial effects of this utility model are as follows:

[0014] These anti-slip stair treads feature metal screws that effectively enhance their slip resistance, making them less prone to slipping. The screws also create a gap between the shoe sole and the anti-slip surface when stepped on, preventing snow or ice from accumulating and maintaining slip resistance. Drainage holes allow water to drain away, preventing the tread surface from freezing and allowing snow to accumulate, further ensuring the treads remain slip-resistant. This effectively reduces the risk of falls and injuries caused by slipping while going up and down stairs. It can be easily installed on existing staircases without dismantling them, facilitating easy retrofitting of existing staircases. It solves the problem of existing stair treads easily becoming covered and losing their slip resistance. Attached Figure Description

[0022] This anti-slip stair tread consists of an anti-slip plate 1, metal screws 2, and side plates 3. The anti-slip plate 1 is evenly distributed with metal screws 2 to increase the grip (friction) of the shoe sole on the tread, thereby effectively increasing its anti-slip capability and preventing slipping when walking on it. Simultaneously, the protruding metal screws 2 keep the shoe sole away from the anti-slip plate 1, preventing snow or ice from covering the screws 2, thus maintaining the tread's anti-slip capability. Drainage holes 4 are provided on the anti-slip plate 1 between the metal screws 2. These holes drain water or collect snow, preventing ice formation and effectively preventing the metal screws 2 from being covered, thus maintaining the tread's anti-slip capability. Furthermore, bolts can be inserted through the drainage holes 4 to secure the anti-slip plate 1 to the staircase. Side plates 3 are provided on both sides of the anti-slip plate 1 to position the anti-slip plate 1, thereby facilitating the assembly of the step.

[0023] Side panel 3 is shaped like an inverted "U". A limiting claw 5 is provided on the inner bottom end of side panel 3 to restrict the position of side panel 3, thereby restricting the position of anti-slip plate 1. Even after the bolts are loosened, the limiting claw 5 can still restrain the tread, fixing it to the stairs. The inverted "U" shape of side panel 3 ensures that the ends of side panel 3 are not obstructed by the limiting claw 5, thus ensuring that water can drain from both ends of side panel 3 and preventing water from accumulating and freezing on anti-slip plate 1. Side panel 3 is made of soft plastic to allow the limiting claw 5 to engage with the bottom of the stairs.

[0024] This anti-slip stair tread is suitable for retrofitting stair treads that are easy to drill (such as patterned plates) or have built-in channels (such as gratings). During retrofitting, the limiting claw 5 of the tread is pried open and then snapped into the bottom of the original stair tread. After the limiting claw 5 is snapped in place, bolts are inserted sequentially into the drainage holes 4 and the original stair tread at both ends of the anti-slip plate 1. The anti-slip plate 1 is then fixed to the original stair tread with bolts, completing the installation. Example 2

[0025] This anti-slip stair tread consists of an anti-slip plate 1, metal screws 2, and side plates 3. The anti-slip plate 1 is evenly distributed with metal screws 2 to increase the grip (friction) of the shoe sole on the tread, thereby effectively increasing its anti-slip capability and preventing slipping when walking on it. Simultaneously, the protruding metal screws 2 keep the shoe sole away from the anti-slip plate 1, preventing snow or ice from covering the screws 2, thus maintaining the tread's anti-slip capability. Drainage holes 4 are provided on the anti-slip plate 1 between the metal screws 2. These holes drain water or collect snow, preventing ice formation and effectively preventing the metal screws 2 from being covered, thus maintaining the tread's anti-slip capability. Furthermore, bolts can be inserted through the drainage holes 4 to secure the anti-slip plate 1 to the staircase. Fasteners are provided at both ends of the anti-slip plate 1 to fix the step to the original stair steps, thus completing the modification.

[0026] The fastener consists of an upper clamping plate 6, a lower clamping plate 7, clamping bolts 8, a pressure plate 9, and a tightening bolt 10. The upper clamping plate 6 and the lower clamping plate 7 are spaced apart vertically, and the upper clamping plate 6 is connected to the lower clamping plate 7 by the clamping bolts 8. A pressure plate 9 is located below the end of the upper clamping plate 6 on the inner side of the clamping bolts 8, and the pressure plate 9 is connected to the upper clamping plate 6 by the tightening bolts 10. The pressure plate 9 abuts against the anti-slip plate 1. The upper clamping plate 6 and the lower clamping plate 7, together with the clamping bolts 8, can fix the upper clamping plate 6 to both sides of the staircase, and then the pressure plate 9 can be tightened onto the anti-slip plate 1 by the tightening bolts 10, thereby fixing the anti-slip plate 1 to the staircase and making the step less likely to shift during use.

[0027] The bottom of the pressure plate 9 is provided with a claw 11, which is inserted into the drain hole 4 at the end of the anti-slip plate 1. The function of the claw 11 is to enhance the limiting effect of the pressure plate 9 on the anti-slip plate 1, further prevent the anti-slip plate 1 from shifting, and ensure that it is not easy to shift when stepping on the pedal.

[0028] The upper clamping plate 6 and the lower clamping plate 7 are each evenly distributed with strip-shaped holes 12, which are fitted with clamping bolts 8. The function of the strip-shaped holes 12 is to adjust the position of the clamping bolts 8 so that the clamping bolts 8 can clamp the upper clamping plate 6 and the lower clamping plate 7 against the side of the staircase. By keeping the clamping bolts 8 against the side of the staircase, the force distribution among the upper clamping plate 6, the lower clamping plate 7, and the clamping bolts 8 is optimized, ensuring a tight clamping.

[0029] This anti-slip stair tread is suitable for retrofitting stair treads where drilling is inconvenient (such as cement or thick steel treads). During retrofitting, the upper clamping plate 6 and lower clamping plate 7 are clamped to both sides of the staircase using clamping bolts 8 (if one side of the staircase is against a wall or the interior space is too small, fasteners can be installed only on the outside of the staircase). After the upper clamping plate 6 is fixed, the anti-slip plate 1 is laid flat on the original stair tread. The claws 11 of the pressure plate 9 are inserted into the drainage holes 4 at the end of the anti-slip plate 1. The pressure plate 9 is then pressed firmly onto the anti-slip plate 1 using clamping bolts 10, thus fixing the anti-slip plate 1 to the original stair tread and completing the retrofit.

[0030] The anti-slip stair treads are effectively reinforced with metal screws 2, making them less prone to slipping. The screws 2 also create a gap between the shoe sole and the anti-slip plate 1 when stepped on, ensuring that snow or ice will not easily accumulate and maintain the anti-slip capability. Drainage holes 4 allow water to drain, preventing the tread surface from freezing and allowing snow to accumulate, further ensuring the treads remain slip-resistant and maintaining their anti-slip ability. This effectively reduces falls and injuries caused by slipping when going up and down stairs. It can be easily installed on existing staircases without dismantling them, facilitating easy retrofitting of existing staircases. It solves the problem of existing stair treads easily becoming covered and losing their anti-slip capability.
