An easy-to-clean stair tread surface structure

Abstract

This application discloses an easy-to-clean escalator tread surface structure. A cleaning strip covering the inner bottom surface of the escalator tread is disposed within a groove formed by the ribs of the tread. An elastic member is positioned between the bottom of the cleaning strip and the inner bottom surface of the groove. This elastic member drives the cleaning strip to detach from the inner bottom surface of the groove, allowing the comb teeth to press against the surface of the cleaning strip and move horizontally, compressing the elastic member. The cleaning strip, covering the inner bottom surface of the escalator tread, is pressed against the comb teeth entering the groove by the elastic member. The comb teeth effectively remove debris from the surface of the cleaning strip. Because the cleaning strip is always in contact with the comb teeth under the action of the elastic member, the gap between the comb teeth and the inner bottom surface of the groove is eliminated. This prevents debris from entering the gap, making it difficult for the comb teeth to clean and increasing the accumulation of debris. This achieves effective cleaning during escalator operation, avoids breakage of the comb teeth due to obstruction by debris, and prevents frequent escalator shutdowns due to malfunctions.

Description

Technical Field

[0001] This application relates to the field of escalator technology, and in particular to an easy-to-clean escalator step surface structure. Background Technology

[0002] The step treads are composed of multiple ribs spaced at intervals, such as... Figure 1-2 As shown, grooves are formed between adjacent ribs, and the top surface of each rib can be designed with a non-slip rough surface. Multiple ribs can increase the stability (non-slip) when standing while riding, ensuring the safety of escalator riding. Comb plates are installed at the upper and lower ends of the escalator (on the floor surfaces of the upper and lower floors). The front end of the comb plate has multiple comb teeth. During continuous operation of the steps, the comb teeth of the comb plate will embed into the grooves of the steps. With the continuous operation of the escalator, the grooves of each step will move and nest onto each comb tooth. The functions of the escalator comb plate are as follows:

[0003] Safety precautions: to prevent foreign objects from being caught in the air and causing injury to passengers;

[0004] Preventing foreign objects: When passengers accidentally drop small items such as shoelaces, clothing hems, or keys, the comb plate can prevent them from being caught in the gap between the steps and the skirt board, avoiding equipment damage or fire risks.

[0005] Reduce the risk of pinching injuries: The close fit between the comb teeth and the step teeth can reduce the gap and prevent passengers' toes or shoe soles from being pinched. Especially when passengers are going up or down the escalator, the comb teeth can provide clear boundary indications and reduce the probability of accidents.

[0006] Structural connection: Ensures smooth operation of the ladder;

[0007] Guiding function: The comb teeth are arranged in the same direction as the movement of the steps, guiding passengers to take steps naturally and reducing falls caused by confusion.

[0008] Ease of cleaning and maintenance: The comb plate is usually fixed by bolts or clips, which makes it easy to clean the dust and debris in the grooves of the steps regularly and prevent foreign objects from accumulating and affecting the operation of the equipment.

[0009] During long-term continuous operation, escalators carry a large number of passengers, inevitably resulting in debris remaining on the steps. Figure 3 As shown), during the operation of the ladder, when the comb teeth of the comb plate enter the grooves of the ladder treads, as... Figure 4-6As shown, the comb teeth remove residual debris from the grooves to ensure the cleanliness of the step treads. When the debris is sticky, such as chewing gum, the stepping of passengers causes it to become further embedded in the grooves. The pre-existing gap between the comb teeth and the bottom surface of the grooves allows the comb teeth to further compress the embedded debris, making it adhere to the bottom surface of the grooves. Figure 7 As shown in the diagram, the debris cannot be effectively removed. At the same time, the debris adheres and accumulates on the bottom surface of the groove, further increasing the amount of debris. This causes the comb teeth to jam in the groove, which can easily lead to comb tooth breakage and elevator malfunctions and shutdowns. Summary of the Invention

[0010] To address the aforementioned problems, this application aims to provide an easy-to-clean stair tread surface structure, which eliminates the gap between the comb teeth and the grooves through a cleaning strip, thereby preventing debris from being pressed against the bottom surface of the grooves by the comb teeth and further accumulating, which could lead to comb tooth breakage and elevator malfunction and shutdown.

[0011] To achieve the above objectives, the technical solution adopted in this application is as follows: an easy-to-clean escalator tread surface structure, wherein the escalator tread is composed of multiple ribs spaced apart, and a groove is formed between adjacent ribs. During continuous operation of the escalator tread, the comb teeth of the comb plate at the end of the escalator are embedded into the groove, and the escalator tread moves horizontally relative to the comb plate. A cleaning strip covering the inner bottom surface of the groove is provided in the groove, and an elastic member is provided between the bottom of the cleaning strip and the inner bottom surface of the groove. The elastic member drives the cleaning strip to detach from the inner bottom surface of the groove, and the comb teeth can press against the surface of the cleaning strip and move horizontally to squeeze the elastic member.

[0012] Preferably, the cleaning strip is inclined toward the comb plate.

[0013] Preferably, the elastic member is an elastic plate with an arc-shaped structure on the bottom surface of the groove and on one side of the comb plate. The end of the elastic plate is connected to the cleaning strip and drives the cleaning strip to be suspended in the groove.

[0014] Preferably, the elastic member is a spring spaced at intervals on the bottom surface of the groove, and the height of the spring increases sequentially in the direction away from the comb plate.

[0015] The beneficial effects of this application are as follows: This application provides a cleaning strip covering the inner bottom surface of the groove in the step tread. Through an elastic component, the cleaning strip can press against the comb teeth entering the groove, and the comb teeth can effectively remove debris from the surface of the cleaning strip. Under the action of the elastic component, the cleaning strip is always in contact with the comb teeth, eliminating the gap between the comb teeth and the inner bottom surface of the groove. This prevents debris from entering the gap, making it difficult for the comb teeth to clean and increasing the accumulation of debris. This achieves effective cleaning during escalator operation, avoids breakage of the comb teeth due to obstruction by debris, and prevents frequent escalator shutdowns due to malfunctions.

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] See attached document Figures 1-12 The illustration shows an easy-to-clean escalator tread surface structure. The escalator tread 1 is composed of multiple spaced ribs 11, with grooves 1a formed between adjacent ribs 11. During continuous operation of the escalator tread 1, the comb teeth 21 of the comb plate 2 at the end of the escalator embed into the grooves 1a, and the escalator tread 1 moves horizontally relative to the comb plate 2. During escalator operation, the comb teeth 21 of the comb plate 2 enter the grooves 1a of the escalator tread 1, effectively removing debris from the grooves. To address the problem of sticky debris (shown as number 6 in the figure) being further pressed against the bottom surface of the groove by the comb teeth when passengers step into it, thus increasing the accumulation of debris, this application provides an easy-to-clean escalator tread surface structure, such as... Figure 8-9 As shown, this application provides a cleaning strip 3 covering the inner bottom surface of the groove 1a. The strip's width is slightly smaller than the inner width of the groove 1a, allowing it to move up and down within the groove 1a while simultaneously covering the area inside. An elastic member is provided between the bottom of the cleaning strip 3 and the inner bottom surface of the groove 1a. This elastic member causes the cleaning strip 3 to detach from the inner bottom surface of the groove 1a. The comb teeth 21 can press against the surface of the cleaning strip 3 and move horizontally, squeezing the elastic member. The cleaning process is as follows: During escalator operation, debris is stepped on and collects on the cleaning strip 3. When the comb teeth 21 enter the groove 1a, the elasticity of the elastic member causes the cleaning strip 3 to abut against the comb teeth 21, meaning the front end of the comb teeth moves against the surface of the cleaning strip 3, effectively removing debris from its surface. Under the action of the elastic component, the cleaning strip 3 always abuts against the comb teeth 21, which can eliminate the gap between the comb teeth 21 and the bottom surface of the groove 1a, thereby preventing debris from entering the gap and making it difficult to clean the comb teeth 21 and increasing the amount of debris, thus achieving effective cleaning during the operation of the escalator.

[0030] like Figure 6 As shown, the front part of the comb teeth 21 has a beveled structure. To allow the debris removed by the comb teeth 21 to transfer to the surface of the comb teeth 21 and detach from the step tread 1, preferably as shown in the figure... Figure 9 As shown, the cleaning strip 3 is inclined towards the comb plate 2. After the comb 21 removes the debris from the cleaning strip 3, as the steps continue to move, the debris is pushed along the slope of the surface of the cleaning strip 3 by the comb 21, while the step 1 continues to push the debris towards the comb 21. Under the combined action of this pushing inertia and the slope, the debris can be transferred to the comb 21 after leaving the surface of the cleaning strip 3. Compared with the horizontally arranged cleaning strip 3, this method can effectively transfer the debris.

[0031] Example 1

[0032] like Figure 8-10 As shown, the elastic member is an elastic plate 4 with an arc-shaped structure on the bottom surface of the groove 1a and on one side of the comb plate 2. The end of the elastic plate 4 is connected to the cleaning strip 3, causing the cleaning strip 3 to be suspended within the groove 1a. The arc-shaped structure of the elastic plate 4 allows its bottom end to be fixed to the bottom surface of the groove 1a, while its other end can be horizontally connected to the sloped cleaning strip 3. The elastic plate 4 drives the cleaning strip 3 to tilt upwards and press against the comb teeth 21 that have entered the groove 1a. Preferably, the elastic plate 4 and the cleaning strip 3 are integrally formed, with the whole being a thin metal sheet structure. The bent elastic plate 4 has a downward elastic force.

[0033] Example 2

[0034] like Figure 11 As shown, the elastic component is a spring 5 spaced at intervals on the bottom surface of the groove 1a, with the height of the spring 5 increasing sequentially in the direction away from the comb plate 2, causing the cleaning strip 3 to be in an inclined state. The elastic action of the spring 5 drives the cleaning strip 3 to abut against the bottom surface of the comb teeth 21, removing debris from the cleaning strip 3. Alternatively, the spring 5 can be preferably an elastic rubber pad, with an embedding groove formed on the bottom surface of the groove 1a to embed and position the elastic rubber pad. This also provides an upward elastic action on the cleaning strip 3.

[0035] To avoid debris remaining on the surface of the comb plate 2 after removal, which could cause passengers to step on it, preferably, such as Figure 12 As shown, a debris groove 2a is formed along the width of the escalator on the surface of the comb plate 2 behind the comb teeth 21. The debris removed is driven by the inertia of the escalator steps to enter the debris groove and accumulate, thus avoiding the problem of being stepped on again while remaining on the surface of the comb plate 2. In environments where escalators are used, such as shopping malls and hospitals, cleaning staff usually perform intermittent cleaning, which can promptly remove the debris accumulated in the debris groove.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
