In these systems, the lid locking mechanism usually consists of a single safety element or It is based on a limited number of locking components. It moves depending on internal pressure. 2 While safety pins and locking elements provide a certain level of security, Due to the limited mechanical redundancy in these systems, part wear and tear, and production issues... safety tolerances, deformations or user-induced stresses Performance may decrease. In a significant number of known systems, the travel distance of the locking elements is 5 an independent stroke limiting mechanism that provides precise control This is not the case. This situation causes the locking parts to move excessively. increased mechanical impact loads, part deformations, premature lock release and prolonged use can lead to a decrease in the precision of mechanical operation. It is possible. 10 On the other hand, in existing valve systems, the internal pressure does not reach a safe level before... The mechanisms that prevent the lid from opening are usually a single-acting safety device. It operates depending on its component.

This Therefore, existing systems offer mechanical reliability, operational stability, and a long service life. and it does not always provide the desired performance in terms of user security. For these reasons, physically opening the lid before the internal pressure drops to a safe level is prohibited. double safety mechanism with pressure-sensitive mechanical locking system that prevents jamming Used together, the movement of the locking elements is controlled by a stroke limiting mechanism. 25 Based entirely on mechanical principles, its reliability, safety in use and operation A new pressure cooker lid was needed to increase its stability.

Lid control lever Description of the Invention: The invention relates to the safe operation of the lid due to the internal pressure generated during pressure cooking processes. ensuring the lid remains locked in place until the internal pressure drops to a safe level. It has a multi-stage mechanical safety architecture that physically prevents it from opening. Double safety, pressure-sensitive stroke limiter operating entirely on mechanical principles. and relates to a pressure cooker lid (1) with a stepped mechanical locking mechanism. In the system developed within the scope of the invention, the lid body (2) is mounted on the pot body (3) 15 It is designed to be placed in a way that the lid body (2) is formed during cooking. It is manufactured to maintain its structural rigidity against pressure while also being interlocking. It serves as the support for all the movable mechanical elements of the system. All mechanical elements located inside the cover body (2) during operation 20 that will allow for the balanced distribution of axial and radial loads that may occur. It is positioned in this way. The circumferential locking collar (4) positioned around the cover body (2) secures the cover one of the main support elements that ensures circumferential locking with the pot body (3) It is one of the surrounding locking collars (4), carrier locks that work together with the cover body (2). It is mechanically attached to the chassis (5). The carrier lock chassis (5) is only for locking 25 a rigid structure that not only supports its components but also regulates load transfer It creates a mechanical frame. Thus, the forces generated during operation are distributed to a certain extent. It is distributed throughout the system, rather than being concentrated in one area. The circumferential locking collar (4) is attached around the cover body (2) without interruption or one at a time. Because it works by creating complementary locking zones, the locking force is 30 It is not concentrated only in certain areas, but is more homogeneous along the perimeter of the lid. It is distributed in this way. Thus, local events that may occur on the cover body (2) 6 Stress increases are reduced, the risk of mechanical deformation is lowered, and sealing is improved. This contributes to the environmental protection of its performance. In addition, the carrier lock chassis (5) reacts to the circumferential locking collar (4). their forces are the main mechanical locking bolt (6), secondary safety bolt (7) and the cover by distributing the 5 that may occur on the mechanism evenly between the body (2) It reduces the effects of torsional and bending. Thus, the locking mechanism has a longer lifespan. Geometric stability is maintained throughout prolonged use. The main body is placed to move linearly on the carrier lock chassis (5). The mechanical locking bolt (6) is the main one that performs the basic locking function of the lid. It is a safety element. The main mechanical locking bolt (6) locks when the lid is closed. It moves into position and remains mechanically fixed until the lock is released. This The movement of the slide is not only controlled by the user, but also... also continuously by the pressure-sensitive mechanism within the system It is being monitored. In addition to the main mechanical locking bolt (6), a secondary safety bolt (7) operates, 15 It functions as a backup safety element. The secondary safety bolt (7) is the main The bolt may not be able to lock completely for any reason, it may be worn or deformed. It intervenes and closes the lid if it is damaged or subjected to a loss of tolerance. This constitutes the second level of security, preventing unintentional activation. Thus, the system By moving away from dependence on a single mechanical element, a multi-stage safety structure is achieved. is being done. One of the most important safety components of the system is the pressure-sensitive safety pin (8), It operates in direct interaction with the internal pressure created inside the lid. Pressure As it rises, the safety pin (8) moves axially, blocking the locking system. This initiates mechanical transmission. Unless the internal pressure drops to a safe level, 25 The safety pin (8) does not allow the locking mechanism to be released. The pressure-sensitive safety pin (8) returns with the fluid pressure acting on it. depending on the balance between the counterforce created by the return spring (10) Its position changes. As the internal pressure increases, the fluid force overcomes the spring force. When the pressure decreases, the return spring (10) returns the safety pin to its initial position. This allows the system to operate without needing any external power source. It operates entirely on the principle of mechanical balance. 7 Pressure-sensitive safety pin (8), precise guidance of its linear motion. For this purpose, the pressure pin moves inside the guide housing (9). The pressure pin The guide housing (9) reduces the bending forces that may occur on the pin, friction limiting irregular movements caused by the source and ensuring the safety mechanism lasts for a long time. This contributes to working with the same precision. 5 Once the pressure effect is relieved, the safety pin is returned to its initial position. A pressure pin return spring (10) is used so that it can rotate in this way. Pressure The safety pin (8) returns to its initial position when the internal pressure decreases, as indicated by the return spring (10). By rotating it, the system is prepared for the new usage cycle. Thus, the mechanism automatically completes the process without requiring additional user intervention. It is being reset. The movement distances of the main mechanical locking bolt (6) and the secondary safety bolt (7) The stroke is limited by the stroke limiting stopper (11). The stroke limiting stopper (11), by preventing moving elements from exceeding their design limits and preventing excessive movement. This reduces mechanical stresses that may arise. Thus, the bolts are 15 times less than necessary. Excessive advancement or retreat is prevented, and working precision is maintained. The stroke limiting mechanism only determines the maximum range of motion. not only that, but also the possibility of problems occurring as the moving elements reach their final position It also contributes to reducing impact energy. Thus, mechanical contact Impact loads that may occur on their surfaces are reduced, and operating cycles are 20. The effects of fatigue that occur throughout the process are limited. The operating limits of the stroke limiter stopper (11) are set via the stroke adjustment slot (12). The stroke adjustment slot (12) is determined to balance production tolerances and assembly. increasing its accuracy and ensuring the same mechanical behavior in different production batches. It enables its protection. 25 A locking cam is used to convert the locking motion into a linear sliding motion. (13) is used. The locking cam (13) contacts the cam tracking surface (14). converting user-applied rotational motion into controlled linear motion. It rotates the device. This reduces sudden impact loads and makes the locking process more stable. This is done in this way. 30 The movement received from the locking cam (13) is transmitted to the other side of the system via the locking transfer lever (15). It is transmitted to its moving parts. The locking transmission lever (15) is around the pivot shaft (16). by rotating in a controlled manner, both the main mechanical locking bolt (6) and the secondary 8 It ensures that the safety bolt (7) moves synchronously. In this way, all Mechanical elements work in a coordinated manner within a single chain of motion. Locking cam (13), cam tracking surface (14), locking transfer lever (15) and articulated shaft (16) The mechanical transmission chain created by the system, rotation applied by the user 5. This provides a relatively low control force applied by the user. main Higher on the mechanical locking bolt (6) and secondary safety bolt (7) It can generate a locking force. Thanks to this mechanical force transmission, the locking elements are powered solely by their own spring 10 not only by their forces, but also by the mechanical advantage created by the cam mechanism. It also benefits from this. Thus, even under high internal pressure, the locking surfaces adhere to each other. It is constantly being pressed down, reducing the possibility of loosening and ensuring a high level of mechanical safety. is being increased. The movement transmitted by the lock transfer lever (15) is the first 15 in the system. Simultaneous operation of the first safety latch (17) and the second safety latch (18) The first safety latch (17) locks the main mechanical locking bolt (6). the first safety measure that ensures it is held securely in position It consists of the second safety latch (18) and the first safety latch (17). It operates independently and for any reason the first safety latch (17) 20 An additional mechanical locking mechanism in case it cannot fully perform its function. It enhances system security by creating a single locking element in the invention. Achieve a dual safety architecture that is independent, mutually validating, and operates sequentially. is being done. The operating cycle of the first safety latch (17) and the second safety latch (18) is 25 In order to maintain stability, a latch return spring (19) is used. The latch return spring (19) releases the locking force after both Return the safety latch to its starting position to enable the system's next use. This ensures that it is ready for the cycle. It also protects the latches from vibration and impact. or stable 30 unaffected by minor mechanical oscillations that may occur during use. This helps them maintain their positions. by the main mechanical locking bolt (6) and the first safety latch (17) The locking force created is the mechanical locking block (20) and the lock counter block (21) 9 Thanks to the mechanical interlocking that occurs between them, the pot lid stays securely in place. It ensures that it is kept closed in this way. Mechanical locking block (20), cover body (2) While being carried on it, the locking counter block (21) makes mechanical contact with the pot body (3). by creating a physical mechanism that prevents the lid from separating even under high internal pressure. This prevents the load from being distributed over a wide contact area. Locking surfaces allow the load to be spread over a large contact area. 5 Because it is designed to provide this, point stresses are reduced and long-term This prevents surface deformations that may occur as a result of use. In operating conditions where the internal pressure is above the safe level, pressure-dependent The blocking lever (22) is activated. The pressure-dependent blocking lever (22) is pressure-sensitive. By mechanically sensing the linear motion generated by the safety pin (8), 10 This prevents the release of the locking transfer lever (15). Thus, the user Even if the cover control lever (37) is moved, the main mechanical locking bolt (6) remains in place. The secondary safety bolt (7) cannot move in the unlocking direction. This structure, inside It is physically impossible to open the lid until the pressure has completely dropped. It brings. The pressure-dependent locking lever (22) is directly on the lock transfer lever (15). Instead of acting as a stopper, a second safety block plate (27) works in conjunction with it. It creates a mechanical verification stage. Thus, a single mechanical part Even in the event of malfunction or wear, the locking mechanism may not unintentionally fail. The resolution is being prevented. Thanks to this design, the system can not only detect pressure but also two different 20 It operates based on the simultaneous verification of the mechanical safety element. The movement created by the pressure-sensitive safety pin (8) is more controlled. Pressure transfer cam (23) for the purpose of transferring pressure to the blocking arm (22) It is used. The pressure transmission cam (23) transmits linear motion with a specific curve profile. by converting the blocked arm into mechanical motion along only 25 predetermined lines. It activates when the stroke amount is reached. Thus, sudden pressure Unnecessary mechanical movements that may result from changes are prevented, the system It only performs its locking function under actual operating conditions. Once the internal pressure has dropped to a safe level, the user can remove the lid in a controlled manner. A controlled release lever (24) is used to enable it to open. Controlled 30 The release lever (24) is released after the pressure-dependent blocking lever (22) is released. It is designed to operate only within a specified sequence of movements. Thus The opening action performed by the user is directly connected to the main slide. It is not transferred; first, the security mechanism is verified. This Thanks to this arrangement, the unintentional release of the locking system is significantly reduced. It is being blocked. For the purpose of operating the controlled release lever (24) by the user. The release button (25) is used. The release button (25) is 5 positioned on the lid body (2) to ensure ergonomic use and is only mechanically activated when the internal pressure drops to a safe level. This results in a controlled release of the force applied by the user. It is transferred to the arm (24) and the locking system moves in a predetermined sequence It is being resolved within. 10 The release button (25) can return to its original position after each use. For this purpose, the button return spring (26) is used. The button return spring (26), By automatically returning the release button (25) to the starting position, the system This ensures that it is ready for the new usage cycle. In addition, the button... by preventing it from remaining in the semi-open position, ensuring the mechanism operates continuously in the same way. 15 This helps to preserve its characteristic properties. The safety block plate (27) located within the system is different from the locking mechanism. It functions as a mechanical transition element between the working phases. Safety The blocking plate (27) can only be used when the necessary safety conditions are met, thus blocking the chain of motion. It allows it to continue, otherwise it blocks the locking mechanism. 20 Thus, independently operating security elements are controlled by a single mechanical verification system. They are brought together within the system. The locking mechanism is engaged gradually, using a stepped lock. Step (28) is used. Step lock step (28) closes the lid completely with a single movement. by preventing it from being released, the lock-unlock process involves multiple mechanical 25 It divides it into stages. In the first stage, security verification is performed, the second In the first stage, the mechanical locking load is reduced, and in the final stage, the lid is controlled. It is made to be able to open in this way. Thanks to this structure, it can be opened under high pressure. The possibility of sudden lid openings is effectively prevented. The steam pressure generated inside the lid during the cooking process is controlled to 30 A pressure relief channel (29) was created for the purpose of directing the pressure. channel (29) follows the determined flow path of the pressure formed inside the cooking chamber. This ensures that the channel reaches the pressure relief valve (30) safely. 11 Its geometry will prevent sudden changes in flow direction, reduce turbulence, and It is designed to stabilize pressure transmission. Thus, the internal pressure is only The system is directed to the evacuation system when the specified mechanical safety conditions are met. The pressure relief valve (30), which works in conjunction with the pressure relief channel (29), cooking If the internal pressure during the process exceeds the specified safety limits, 5 It is a safety element that performs the controlled release operation. Pressure relief valve (30), Under normal operating conditions, it maintains its closed position, only the internal pressure... It opens to release excess pressure safely if a predetermined threshold value is exceeded. This allows the material to be transferred outside the system in this way. Thus, both the cooking performance both protection and mechanical stresses that may occur due to excessive pressure are important. 10 is being reduced to a certain extent. In order for the pressure relief valve (30) to function reliably, the valve seat (31) The valve seat (31) is formed to precisely accommodate the axial movement of the valve. It directs, ensures the centering of the valve body, and opens and closes. It contributes to maintaining the leak-proof contact surface throughout its cycles. 15 In addition, the valve seat (31) protects against wear that may occur during the service life of the valve. It acts as a mechanical support to ensure that the level of support remains at a minimum. A pressure-resistant seal between the lid body (2) and the pot body (3) In order to create a sealing gasket (32), a sealing gasket is used. (32), when the lid is closed, the cooking chamber is compressed evenly around the circumference 20 It prevents the pressure inside from escaping to the outside environment. The geometry of the gasket and The amount of compression will ensure that it retains its elasticity both at high temperatures and for a long time. to maintain its sealing performance through prolonged use This is determined by the increase in internal pressure during the cooking process, which helps to seal the leak. The axial compression created between the gasket (32), the lid body (2) and the pot body (3) 25 Due to the force, it changes shape in a controlled manner within the gasket seat (33). This elastic deformation closes the microscopic gaps at the contact surface. This helps to further strengthen the seal as the pressure increases. The gasket seat (33) also prevents the sealing gasket (32) from being over-tightened. It also acts as a mechanical restraint, extending the service life of the gasket by 30%. and maintaining similar sealing performance across different service cycles It contributes. 12 In order to hold the sealing gasket (32) in the correct position, the gasket seat (33) It has been created. The gasket seat (33) accommodates axial displacements that may occur along the gasket and By preventing rotational movements, the sealing element remains in the same position during each use. It ensures its operation. In addition, the gasket bearing (33) acts on the gasket. It contributes to the circumferentially balanced distribution of compressive forces and 5 It prevents excessive deformation in certain areas. Main mechanical locking mechanism that performs linear movement within the lid mechanism. the smooth operation of the bolt (6), secondary safety bolt (7) and related motion transmission elements. A guide rail (34) was created so that it can work in the direction. The guide rail (34) By preventing moving parts from going off-axis, it reduces friction forces, 10 It increases mechanical precision and accuracy of movement throughout long-term use. It protects the locking mechanism so that it moves the same way in every usage cycle. It is possible for it to demonstrate its characteristic. In order to reliably determine the limits of movement in the system, mechanical endpoints are required. The position stopper (35) is used. The mechanical end position stopper (35) is movable 15 by preventing the elements from going beyond the design limits of the locking mechanism It precisely determines the final operating position. This enables the main mechanical locking mechanism. bolt (6), secondary safety bolt (7), lock transfer lever (15) and other movable The elements reach the same mechanical position at the end of each cycle, ensuring the system's adjustment stability. is protected. 20 Potential user stresses, high impact loads, or unexpected mechanical stresses. the result is to prevent moving elements from exceeding their design limits. An overstroke safety stop (36) has been created for this purpose. Overstroke safety stop (36), A second safety level that operates independently of the mechanical end position stopper (35). it creates and during unusual loads the structural 25 of the mechanism It maintains its integrity. Thus, it prevents both moving parts from being deformed. both prevention and maintenance of mechanical reliability during long-term use. is being done. The lid allows the user to perform locking and unlocking operations. The control lever (37) is ergonomically positioned on the cover body (2). 30 The lid control lever (37) locks the rotational force applied by the user. transferring to the cam (13), from there to the lock transfer lever (15) and then to the main mechanical It transmits the movement to the locking bolt (6) and the secondary safety bolt (7). However, this movement 13 chain, only pressure-sensitive safety pin (8), pressure-dependent blocking lever (22), safety safe working conditions of the blocking plate (27) and the controlled release lever (24) It is completed upon verification. Thus, it is controlled by the user. Applying force to the arm (37) alone is not sufficient to open the lid, After the system completes all security verifications, it locks in a controlled manner. 5 The decoding process is being carried out. As a result, the invention developed within the scope of this design features a double-safety, pressure-sensitive stroke-limiting system. pressure cooker lid with stepped mechanical locking mechanism (1); pressure sensitive safety mechanism, multi-stage mechanical locking system, double safety structure, controlled release mechanism, stroke limiting device, pressure relief system and 10 Thanks to the integrated and complementary operation of the sealing structure, the existing Higher mechanical reliability compared to pressure cooker lids, higher safety in use, more stable operating characteristics, longer service life and It offers a compact mechanical solution with high manufacturability. The working principle of the mechanical system of the invention is the closing and locking of the lid, pressure 15 safe storage under controlled pressure relief and secure It consists of successive work phases, including reopening. During the first use, the user moves the lid control lever (37) in the closing direction. When this is done, this rotational movement is transmitted directly to the locking cam (13). Locking The cam (13) converts rotational motion into linear motion thanks to its cam profile. transforms and works in constant contact with the cam tracking surface (14) the movement It ensures that it progresses in a controlled manner. The cam tracking surface (14) is formed along the cam tracking surface (14) Sudden impact loads are reduced thanks to mechanical contact, and the locking action is more stable. and is carried out in a controlled manner. The linear motion obtained from the locking cam (13) is transferred via the locking transfer lever (15) 25 The rotational motion is converted around the articulated shaft (16). The articulated shaft (16), It forms the axis of rotation of the motion transmission system and the resulting forces It contributes to the even distribution within the mechanism. Lock transfer As a result of the movement of the lever (15), the main mechanical locking bolt (6) and the secondary safety The bolt (7) moves forward simultaneously, locking the mechanical locking block (20) 30 It directs towards the corresponding block (21). The main mechanical locking bolt (6) forms the first locking stage, while the secondary safety The slide (7) activates after a certain delay, creating the second level of safety. 14 This allows the locking process to be carried out sequentially instead of with a single movement. this is happening, thanks to the mutually reinforcing working characteristics of both exiles. The mechanical safety level is being increased. During the forward movement of the slides, the first safety latch (17) is in the locking position. Passing through, it secures the main mechanical locking bolt (6). Following this, the second 5 By engaging the safety latch (18), both the main bolt (6) and the secondary safety latch are engaged. It mechanically limits the backward movement of the bolt (7). Thus, the locking The process does not depend solely on the mechanical position of the slides; it also involves independent mechanisms. This is verified by two separate latch systems. After the locking process is complete, there should be a gap of 10 between the lid body (2) and the pot body (3). The sealing gasket (32) located circumferentially inside the gasket seat (33) It is compressed. Thanks to this compression, the cooking chamber becomes completely leakproof. The steam pressure generated during cooking is contained within the system. The gasket bearing (33) ensures the circumferentially even distribution of compressive forces. By providing this, it prevents excessive deformation in certain areas. 15 When the cooking process begins, the steam pressure inside the chamber increases, creating a pressure-sensitive environment. It acts on the safety pin (8). The pressure-sensitive safety pin (8) acts on the pressure pin guide. The pressure transfer cam (23) moves axially inside the body (9) It activates the pressure transmission cam (23) and the pressure-dependent blocking arm (22). It directs to the locking position. After this stage, the lid control lever (37) 20 Even if the user attempts to translate it, the mechanical chain of motion is blocked and The locking system cannot be unlocked. The safety lock is activated when the pressure-dependent locking lever (22) moves to the locking position. The safety block plate (27) also becomes active. The safety block plate (27) is released in a controlled manner. by physically closing the path of movement of the release lever (24) by the user 25 This renders any opening attempts ineffective. Thus, the internal pressure... As long as it remains above the safe level, the lid cannot be opened mechanically at all. It is being blocked. Vibrations, temperature changes, and other factors that occur on the mechanism during the cooking process. The positional change of moving parts is prevented due to dynamic loads. This 30 for the purpose of stroke limiter stopper (11), stroke adjustment slot (12), mechanical end position stopper (35) and overstroke safety stop (36) work together to ensure all moving elements only to operate within the movement limits defined during the design phase. This ensures that loosening or damage that may occur as a result of prolonged use is prevented. Excessive loads or user-generated force applications negatively impact system security. It does not affect it in that direction. After the cooking process is complete, the pressure inside the chamber is released in a controlled manner. The pressure relief channel (29) directs the flow to the pressure relief channel (29). transmits to the valve (30), and the pressure relief valve (30) only transmits to the predetermined operating operation. By opening within the pressure limits, excess steam can be safely released to the outside environment. It ensures the transfer of pressure. As the pressure level decreases, the pressure-sensitive safety pin (8), The pressure pin returns to its starting position under the effect of the return spring (10), and accordingly The pressure-dependent locking lever (22) and safety locking plate (27) are in the passive state. The pressure relief valve (30) passes through during the process of the internal pressure reaching a safe level. Since the flow through it continues in a controlled manner, the cover body (2) No sudden pressure difference occurs between the pot body (3). Thus, locking residual pressure in the system before the release of the mechanism They are safely removed. 15 Once the internal pressure reaches a safe level, the user releases the button. (25) applies force. This force is applied to the controlled release lever (24) is transferred and the button return spring (26) is only released after the movement is completed. It returns the button to its initial position. Controlled release lever (24) With this movement, the lock transfer lever (15) is released again, the main mechanical locking 20 The mechanical locking block is activated by the sliding bolt (6) and the secondary safety bolt (7) moving back. (20) separates the lock from the counter block (21). Thus the lid can be opened safely. it is reaching this point. Once the locking elements are fully released, the user can control the lid. By continuing to turn the handle (37) in the direction of opening, the lid body (2), pot 25 It separates from its body (3). Since the internal pressure has been completely relieved beforehand. No sudden lifting force is generated on the lid; the lid separates in a controlled manner. Safe usage is ensured.
