Movement 35 The limiting stopper (10) keeps the amount of deformation within the determined limits. By holding it, it prevents excessive stress on the system components. By the user 6 The applied compressive force is primarily resisted by the flexible upper surface (3), word 5 The subject is the force transfer plate (7) through the flexible carrier plate (5) spreading, controlled elastic deformation along the deformation zone (6) to form and at the same time on the elastic support element (8) and return spring (9) It enables elastic energy storage. Thus, with a single pressing motion, both the surface The deformation and the operation of the passive air displacement mechanism occur simultaneously. 10 It is carried out. The deformation zone (6) is only before the flexible top surface (3) to allow displacement within the defined elastic range of motion It is dimensioned, maintaining rigidity at the edges of the steps while providing controlled movement in the middle section. Elastic deformation is created. This ensures both walking safety. It is protected and the necessary volume change for the passive cleaning function is achieved. 15 is being done. Central particle guiding surface (11) at the bottom of the flexible top surface (3), first side guiding channel (12), second side guiding channel (13), particle guiding protrusions (14) and particle guiding grooves (15) have been created. These structures form the surface Dust and similar particles on it spread from the middle section of the step to the side sections 20 It is designed with a geometry that allows for controlled and precise movement. Air passage with passive air displacement chamber (16) also inside the main body of the step (2). channel (17) is available. Passive during deformation of the flexible upper surface (3). The volume of the air displacement chamber (16) changes, as a result of which the air passage channel (17) a directed air movement is created. One-way air inlet 25 element (18) and unidirectional air outlet element (20), the specified air movement of the said air By ensuring that the airflow occurs in one direction, it prevents the airflow from forming in the opposite direction and It prevents particles removed from the surface from returning to the walking surface.

Dirt collection is done using the pull handle (25) of the container. The container (21) can be removed from the step body, and the accumulated particles can be easily removed. It can be put back in place after being emptied. Passive air displacement chamber. (16), the variable 35 created between the flexible upper surface (3) and the step main body (2). It creates a voluminous, enclosed mechanical volume. The flexible upper surface moves downwards. During the initial movement, the volume in question decreases, and during the return movement, it decreases again. 7 It is expanding. Thus, within the system, only mechanical volume change is dependent on 5 Directed air circulation occurs. Dirt collection tray (21), maintenance during operation, the system operates independently without interfering with other mechanical components of the system. It is arranged in such a way that it can be removed. Thus, only the accumulated particles Removing it is sufficient; the mechanical cleaning system does not need to be decommissioned. Maintenance can be performed. 10 The main body of the step (2) is made of elastomer to reduce vibration and impact effects. The load-bearing capacity of the body is supported by a vibration damper (26). The system assembly is provided by the chassis (27) and chassis mounting foot (28). ladder carrier via connection area (29) and fixing element (30) It is fixed to the construction. Sealing gasket (31), side protection cover (32), 15 The service access cover (33) and the lower housing cover (34) protect the system from external factors. to ensure protection, facilitate maintenance procedures and ensure the safe operation of the internal mechanism.

It is positioned to work in such a way that any problem occurring in any component... Mechanical movement is sequentially transmitted to other components with a single user step. The entire cleaning cycle is completed with this. When the user steps on the step during use, the flexible top surface (3) is controlled to 25 undergoing downward deformation, at the same time in the passive air displacement chamber (16) Due to the resulting volume change, directed air movement occurs. This particle guiding protrusions (14) and particle guiding troughs with air movement (15) The mechanical guidance effect it creates works together with the dust and It transports similar particles to the first and second lateral deflection channels (12, 13). 30 The particles then pass through the side discharge opening (19) into the dirt collection container (21) is being accumulated, and when the user leaves the step, the return spring (9) and elastic support Thanks to element (8), the system returns to its starting position and is ready for the next use. This is happening. The orientation of particles is achieved not only by air movement, but also by... microscopic elastic surface movements occurring on the flexible upper surface over time 35 the mechanical thrust effect created by the particle guiding protrusions (14) together This is achieved as a result of the study. Thus, having different particle sizes 8 The orientation efficiency for particles is increased. During the return movement 5 elastic energy stored by the elastic support element (8) and the return spring (9) It is released in a controlled manner and the system redoes its initial geometry. It wins. Thus, the cleaning cycle does not require any manual reset. It is completed without needing to be done. Thanks to this structure, any electrical energy, motor, sensor or electronic control 10 mechanical force generated solely by the user without the use of a system By utilizing this, a continuously repeated passive cleaning effect is achieved on the step surface. This reduces surface dirt accumulation, maintains hygiene levels, and ensures cleanliness. The frequency of maintenance required for these processes is being reduced. The general structure of the stair step (1) consists of the step main body (2), flexible upper surface (3), 15 non-slip surface coating (4) and side protection cover (32) together form the outer structure of the step. It consists of the main body of the step (2), where all mechanical components are placed. It is a load-bearing structure and at the same time the loads are safely transferred to the lower support chassis (27) It enables the transfer of information. The flexible top surface (3) is elastic when no load is applied to the system. 20 It is held in the upper position by the support element (8) and the return spring (9). Passive The air displacement chamber (16) is in the initial volume. One-way air inlet element (18) and With the one-way air outlet element (20) in the closed position, the air inside the system It maintains its volume. Particle guiding protrusions (14) The grooves (15) extend along the surface and carry 25 particles to be transported by the user. It is ready to be directed. The central particle orientation surface (11) directs dust and dirt on the surface to the first movement along the lateral steering channel (12) and the second lateral steering channel (13) It is designed with a slope so that it will cause the side discharge opening (19) to be directed. It allows the particles to pass into the dirt collection container (21). The dirt collection container 30 (21), container drawer body (22), container guide rail (23), container locking latch (24) and consists of a hopper pull handle (25) which can be easily removed during maintenance. It can be cleaned. Deformation of the flexible upper surface (3) as a result of the force applied by the user to the step Moving downwards along region (6), the pressure transfer plate (7) force is 35 It distributes the air homogeneously and reduces the volume of the passive air displacement chamber (16). The air movement resulting from the volume reduction moves along the air passage channel (17) and 9 It is discharged through the one-way air outlet element (20). Simultaneously, 5 one-way The air inlet element (18) prevents reverse air inlet, ensuring that the air flow is only in the direction of airflow. It ensures that it happens in the desired direction. Particle guiding protrusions during the downward movement of the flexible top surface (3) (14) and particle guiding channels (15) work together with air movement on the surface Dust and similar particles found are directed through the central particle orientation surface (11) 10 It ensures that it is transferred to the first and second side routing channels (12, 13). The particles in question are then collected in the dirt collection container via the side discharge opening (19). (21) are being accumulated. The slope of the orientation channels during particle orientation, the surface The geometry, the effect of gravity, and the elastic surface motion work together to make the particles 15 This facilitates its movement towards the evacuation openings. Flexible top surface (3) during dynamic loading created by the user, elastic small amplitude elasticity occurring between support element (8) and return spring (9) Vibrations also contribute to the separation of particles from the walking surface. Thus Elastic vibration effect working in conjunction with airflow and mechanical guidance structures 20 This increases the probability of particles reaching the guidance channels (12, 13). The return spring (9) and elastic support start when the user leaves the step. element (8) returns the flexible upper surface (3) to its initial position. This return During this time, the passive air displacement chamber (16) expands again and the air inlet is one-way. The element (18) is opened in a controlled manner to allow air to enter the system. 25 Thus, the particles in the dirt collection container (21) are brought back to the walking surface. The system is prevented from moving and is returned to its starting position for the next service cycle. It is turning. Thanks to this operating principle, the system only requires mechanical components created by the user. any electrical energy, motor, sensor or electronic 30 by harnessing force a passive cleaning cycle repeated with each use without requiring a control system It performs this function, reducing particle accumulation on the step surface and cleaning. This contributes to a significant reduction in its need. Within the scope of the invention, flexible top surface (3), natural rubber, synthetic rubber, thermoplastic elastomer, polyurethane elastomer, silicone-based elastomer or similar flexible 35 They can be produced from materials as single-layer or multi-layered. Usage Depending on the area, the coefficient of elasticity, the amount of deformation, and the surface hardness are different. 5 These values ​​can be selected. Non-slip surface coating (4), embossed pattern, micro-rough surface, elastomer coating, abrasive particle coating or similar anti-slip surface It can be created using these structures. Thus, the cleaning function User security is also ensured during this process. 10 Particle guiding protrusions (14) and particle guiding grooves (15) are linear, Curved, radial, zigzag, herringbone, V-shaped, or combinations thereof. It can be arranged in different geometries. Similarly, the first lateral orientation channel (12) and second lateral guidance channel (13), according to the purpose of use of the step 15 with different slopes, different widths or different cross-sectional geometries can be created. Passive air displacement chambers (16) can be created as single volumes or connected to each other. also in the form of a multi-compartment structure consisting of multiple air chambers It can be arranged. The air passage duct (17) may contain one or more ducts. It can also be designed to have different cross-sectional areas, such as those shown. One-way air 20 The inlet element (18) and the one-way air outlet element (20) are elastomer lip valves, leaf valves. valve, flexible membrane valve or similar fully mechanically operated unidirectional flow It can be implemented in the form of elements. Passive air is created by the deformation of the flexible upper surface. The instantaneous pressure difference created in the displacement chamber allows controlled air flow through the air passage channel. by creating flow, it contributes to the transport of light particles in the discharge direction. 25 It provides. The one-way air inlet element (18) and the one-way air outlet element (20) ensure air circulation. by ensuring that the polluted air only flows in a predetermined direction. It restricts its return circulation within the system. Thus, it is removed from the surface. The likelihood of particles being transported back to the walking surface is reduced, and cleaning is 30 The continuity of the cycle is supported. The dirt collection container (21) can be produced in different volumes depending on the area of ​​use. and container drawer body (22), container guide rail (23), container locking latch (24) and the hopper pull handle (25) with different mechanical locking or sliding systems It can be formed. The reservoir contains replaceable filter elements, 35 Particle separator structures or odor-absorbing passive elements can also be used. 11 Step undercarriage frame (27), frame connection foot (28), mounting connection area (29) and 5 fixing element (30), reinforced concrete, steel, aluminum, wood or composite stairs They can be produced in different mounting geometries to suit various systems. Thus, the invention will be used not only in newly manufactured stair systems but also in existing ones. It can also be applied for the purpose of renovating staircases. Provided that the same mechanical working principle is maintained, the step undercarriage chassis (27), chassis 10 connecting foot (28), mounting connection area (29) and fixing element (30), different stair widths, step depths, load capacities, and supporting systems They can be resized to suit their geometries. Thus, the invention adaptability to different building types without changing the basic mechanical working principle. It is possible. 15 Sealing gasket (31), side protection cover (32), service access cover (33) and bottom The protective cover (34) will reduce the entry of water, dust or foreign objects into the system. It can be constructed with different sealing and protection structures. Service access The cover (33) will provide quick access to mechanical components during maintenance operations. It can be arranged in a way that allows it to be opened or removed. 20 The invention applies not only to linear stair treads but also to spiral staircases, on landing staircases, emergency escape staircases, industrial platforms, pedestrian walkways The same applies to transition platforms and similar structural elements that are stepped on. It can be implemented while preserving the mechanical working principle. The cleaning function, As a natural consequence of the pressure force created by the user, each use costs 25. The cycle repeats automatically and does not require any external energy source. It is not needed. Therefore, the invention is mechanically reliable, energy-efficient, and requires low maintenance. It is easy to manufacture, long-lasting, and adaptable to different application areas; a passive self-contained device. It offers a self-cleaning stair step solution. 30 The system independently analyzes each mechanical loading cycle created by the user. It operates in a way that treats it as a cleaning cycle. A user's sequential The mechanical cycles that occur during the steps follow one another, gradually removing the dirt. This ensures that the dirt is transferred to the dirt collection container. The cleaning cycle; the user steps on the step, the flexible top surface deforms 35 exposure to passive air displacement, particle direction, and dirt collection. from the stages of transferring it to the reservoir and the system returning to its initial state 12 This creates a repetitive mechanical cycle. This cycle occurs every 5 This automatically repeats during use and the system's continuous cleaning function. It enables the invention to perform its function. Controlled elastic deformation is achieved in the invention. It is not only used to create surface movement, but also passive ventilation. the mechanical energy source that enables the operation of the displacement system It creates. Thus, the normal walking motion applied to the step by the user is 10 power without the need for any additional mechanical drive mechanism This is sufficient to initiate the cleaning cycle. Each cleaning cycle occurs independently, but sequentially. The mechanical cycles that occur during user transitions are complementary. It works by removing all particles that accumulate on the surface in a single use. 15 Even if not removed, dirt gradually accumulates over successive usage cycles. It is transferred to the collection hopper. Mechanical movement and passive movement occurring during deformation of the flexible top surface (3) The volume change occurring in the air displacement chamber (16) is simultaneously Since this occurs, mechanical particle guidance and directed airflow complement each other 20 It creates two different cleaning mechanisms that complement each other. In this way... compared to systems that use only mechanical sweeping effect or only airflow High particle removal efficiency is achieved. Material selection, deformation. taking into account quantity, fatigue life, environmental conditions and usage intensity It can be determined, and materials with different modulus of elasticity can be used in the same study. 25 It can be used in a way that will satisfy this principle. Particle guiding protrusions (14), particle guiding grooves (15) and central The particle orientation surface (11) works together to direct particles of different sizes prevents the accumulation of particles in certain areas and distributes them across the step width. It ensures that the material is distributed in a controlled manner and delivered to the side discharge openings (19). 30 This reduces localized dirt accumulation on the surface, even with increased usage intensity. is the goal. Air thanks to the one-way air inlet element (18) and one-way air outlet element (20) The flow occurs only in the predetermined direction, and the user steps through the steps. After separation, the particles in the dirt collection container (21) are re-walked 35 This prevents the system from being transported to the surface. Thus, the system undergoes similar processes in each service cycle. It is able to maintain its cleaning performance. 13 The creation of the dirt collection container (21) in a volume independent of the walking surface 5 Thanks to this, the particles removed from the surface do not come into contact with the user again, Maintenance procedures only involve emptying the tank at specific intervals. This can be accomplished. This structure allows cleaning processes to be interrupted during use. It contributes to its continuation without interruption. Step main body (2), pressure transfer plate (7), elastic support element (8) and back 10 Since the return spring (9) is sized to work together, the system can accommodate different users They can also be designed to exhibit similar operating characteristics at different weights. Spring coefficient, elastomer stiffness, or deformation amount can be adjusted as needed. This can be changed depending on the application. Step undercarriage frame (27), frame connection foot (28) and mounting connection area (29), 15 by enabling the controlled transfer of mechanical loads to the structural elements of the system It helps reduce deformation during long-term use. Elastomer The vibration damper (26) can absorb the shocks and vibrations that may occur during walking. by reducing the efficiency of mechanical components, it improves both user comfort and the performance of the mechanical components. It increases the lifespan. The operating limits of mechanical elements are elastic deformation 20 Since it is limited to the region, permanent deformation of the system elements is reduced. The aim is to maintain the operating characteristics during long-term use. The mechanical arrangement described within the scope of the invention is provided as an example only in the description. Not limited to the geometry described, but different methods can achieve the same technical effect.

It enables him to work without hearing anything. The pressure transfer plate (7) distributes the applied load homogeneously along the deformation zone (6). because it distributes it in this way, the flexible top surface (3) collapses only at certain points. is prevented and the cleaning effect is evenly distributed across the step width. 10 This is how the system works, even at different footstep points. It is able to preserve its characteristics.

Because of this, particles removed from the surface are released back into the external environment without being re-released. It is preserved. The container drawer body (22), container guide rail (23), container The locking latch (24) and the hopper pull handle (25) ensure quick and safe maintenance operations. It is designed in a way that will allow it to be carried out in this manner. Elastomer vibration damper (26) serves only as shock damper. not only that, it also reduces sudden load changes that may occur between mechanical components, 30 This situation limits the fatigue of the system elements.
