[0012] The present application provides a lock device. Figure 1 illustrates a particular embodiment of a lock device 100 including a lock housing 10, a lock cylinder assembly 30 disposed within the lock housing 10, and a thumbturn assembly 50 transmissionably coupled to the lock cylinder assembly 30.

[0013] The present application also provides a locking device. Figures 2-3 show a specific embodiment of a locking device 200 comprising a first object 210, a second object 220 and a locking device 100. Here, the locking device 100 is attached to the first object 210 and can inter-engage with the second object 220 to lock the second objects 210 and 220 together or apart. Specifically, the locking device 100 has an unlocked state and a locked state, and in the locked state, the first object 210 to which the locking device 100 is attached is locked to the second object 220 as shown in Figure 3. For example, when the locking device 100 is attached to a door / window, the door / window can be locked to a door frame / window frame to form a private space. As another example, when the locking device 100 is attached to a cabinet door, the cabinet door can be locked to a cabinet body to form a secure space for storing valuables, confidential documents, etc. In an unlocked state, as shown in FIG. 2, a first object 210 to which the lock device 100 is attached can be opened to a second object 220; for example, a door or window can be opened for ventilation, or a drawer can be opened to access documents.

[0014] Please also refer to Figures 4 to 6. The lock cylinder assembly 30 described above is a basic part of the lock device 100, and can be combined with a key (not shown) to lock and unlock the lock device 100. In this embodiment, the lock cylinder assembly 30 includes a lock plug 32, a cylinder tailpiece 34, and a locking member 36. Specifically, the lock plug 32 has a cylindrical structure as a whole and is rotatably arranged in the lock housing 10. A keyhole 321 is provided in the center of the lock plug 32 for inserting a suitable key. After inserting a key into the keyhole 321, the lock plug 32 can be driven and rotated by applying force to rotate the key. The cylinder tailpiece 34 is disposed at the inner end of the lock plug 32 in the axial direction, and the lock plug 32 is driven to rotate the locking member 36 to a locked position or an unlocked position by driving the lock plug 32, which drives the lock body, latch bolt, etc. connected thereto to perform an expansion and contraction movement, thereby realizing the locking and unlocking of the lock device 100. The locking member 36 may be connected to the cylinder tailpiece 34 after being molded separately, or may be integrated with the cylinder tailpiece 34. In the illustrated embodiment, the locking member 36 is a locking hook structure. According to different orientations of the locking hook structure of the locking member 36, the locking member 36 can have different rotation directions when performing a locking operation.

[0015] Please refer to FIG. 7 at the same time. The first clutch mechanism 40 is disposed between the lock plug 32 and the cylinder tailpiece 34, and the first clutch mechanism 40 includes a first drive portion 42 and a first clutch portion 44 that interact with each other. In this embodiment, the first drive portion 42 is disposed at a side end of the lock plug 32 facing the cylinder tailpiece 34, and the first clutch portion 44 is disposed at a side end of the cylinder tailpiece 34 facing the lock plug 32. The first drive portion 42 includes a first drive surface C1 and a second drive surface D1 that face each other. The first clutch portion 44 is formed with an arc-shaped groove 441, and the first clutch portion 44 is formed with a first clutch surface C2 and a second clutch surface D2 on both sides of the arc-shaped groove 441 in the circumferential direction. Preferably, the first drive portion 42 is a drive pin that extends into the arcuate groove 441 of the first clutch portion 44, with the first drive surface C1 corresponding to the first clutch surface C2 and the second drive surface D1 corresponding to the second clutch surface D2. The first drive portion 42 can rotate within the arcuate groove 441 relative to the first clutch portion 44, so that the first drive surface C1 and the first clutch surface C2 come into contact with or separate from each other, and the second drive surface D1 and the second clutch surface D2 come into contact with or separate from each other.

[0016] When the first drive surface C1 of the first drive portion 42 abuts against the first clutch surface C2, the first clutch mechanism 40 is in a first engaged state, and the lock plug 32 can drive the cylinder tailpiece 34 to rotate along a first direction (e.g., counterclockwise). When the second drive surface D1 abuts against the second clutch surface D2, the first clutch mechanism 40 is in a second engaged state, and the lock plug 32 can drive the cylinder tailpiece 34 to rotate along a second direction (e.g., clockwise). When the first drive surface C1 is separated from the first clutch surface C2 and the second drive surface D1 is separated from the second clutch surface D2, the first clutch mechanism 40 is in a disengaged state, and the cylinder tailpiece 34 remains stationary as the lock plug 32 rotates, i.e., the lock plug 32 spins free. Preferably, the central angle corresponding to the distance between the first clutch surface C2 and the second clutch surface D2 (i.e., the arc-shaped groove 441) is about 180 degrees. In the present application, the first clutch mechanism 40 is provided between the lock plug 32 and the cylinder tailpiece 34, so that the lock plug 32 and the cylinder tailpiece 34 have two states, a separated state and an engaged state. Only in the engaged state can the lock plug 32 drive the cylinder tailpiece 34 to rotate and lock or unlock.

[0017] In some embodiments, the first drive portion 42 may be molded separately and then assembled to the lock plug 32, or may be molded integrally with the lock plug 32. The first clutch portion 44 may be molded separately and then assembled to the cylinder tailpiece 34, or may be molded integrally with the cylinder tailpiece 34.

[0018] Also refer to Figure 8. The above-mentioned thumbturn assembly 50 is used for keyless locking of the lock device 100, that is, the lock device 100 is locked without the lock plug 32 being inserted into the key. The thumbturn assembly 50 includes an operating member 52 and a resetting member 54, and the operating member 52 may be a knob or the like, and the resetting member 54 may be a coil spring, a torsion spring, or the like.

[0019] A second clutch mechanism 60 is disposed between the operating member 52 and the cylinder tailpiece 34. The second clutch mechanism 60 includes a second drive portion 62 and a second clutch portion 64 that interact with each other, the second drive portion 62 being connected to the thumbturn assembly 50, and the second clutch portion 64 being connected to the cylinder tailpiece 34. The second clutch mechanism 60 allows the thumbturn assembly 50 and the cylinder tailpiece 34 to have two states, a disengaged state and an engaged state. In the engaged state, the cylinder tailpiece 34 and the locking member 36 can be driven and rotated by the rotation of the operating member 52 to lock. In this way, when using the lock device 100 of the present application, the lock plug 32, the cylinder tailpiece 34, and the locking member 36 can be driven and rotated by the key to lock, and the cylinder tailpiece 34 and the locking member 36 can also be driven and locked by the operating member 52, i.e., keyless locking is realized, improving the convenience of operation.

[0020] The second drive part 62 is an arc-shaped block, and a third drive surface A1 and a fourth drive surface B1 are formed on both sides of the circumferential direction. The second clutch part 64 is also an arc-shaped block, and a third clutch surface A2 and a fourth clutch surface B2 are formed on both sides of the circumferential direction. The second drive part 62 and the second clutch part 64 are arranged coaxially and have the same size, that is, both are arranged on the same ring. The third drive surface A1 and the third clutch surface A2 face each other, and the fourth drive surface B1 and the fourth clutch surface B2 face each other. When the operating member 52 rotates, the third drive surface A1 and the third clutch surface A2 can be brought into contact with each other or separated from each other, and the fourth drive surface B1 and the fourth clutch surface B2 can be brought into contact with each other or separated from each other. Preferably, the central angle corresponding to the circumferential lengths of the second drive portion 62 and the second clutch portion 64 is approximately 90 degrees.

[0021] One end of the return member 54 is connected to the operating member 52, and the other end is connected to a fixed member such as the lock housing 10. When the operating member 52 rotates relative to the lock housing 10 under the action of an external force, the return member 54 is compressed or stretched. When the external force acting on the operating member 52 is canceled, the return member 54 recovers from the deformation, drives the operating member 52 to rotate in the reverse direction and return to its original state. Preferably, positioning portions 59 are disposed on the operating member 52 and the lock housing 10, respectively, and the two positioning portions 59 abut or are inserted into both ends of the return member 54. When the operating member 52 rotates relative to the lock housing 10, the one end of the return member 54 abutting against the operating member 52 rotates with the rotation of the lock housing 10, causing further deformation and forming a return elastic force that returns the operating member 52 in the reverse direction.

[0022] The lock plug 32 is preferably attached within the operating member 52 and the two are frictionally fitted together, so that the lock plug 32 is fixed within the operating member 52 and can rotate synchronously therewith when not affected by external force, but can rotate relative to the lock plug 32 when it receives an external force (such as turning a key). Preferably, a lock tube 56 for installing the lock plug 32 is provided at the center inside the operating member 52, and a through hole 529 is provided at the outer end surface of the operating member 52 at a position corresponding to the lock tube 56, so that the key hole 321 of the lock plug 32 can be exposed. A sliding lock pin may be arranged on the lock plug 32 and / or the lock tube 56, and the length arrangement of the lock pin corresponds to the shape of the notch of the key, and the lock plug 32 can be rotated relative to the lock tube 56 by inserting the key to slide the lock pin and open the lock.

[0023] In the following, the operation process of the lock device 100 of the present application will be described using an example in which counterclockwise rotation is used to lock and clockwise rotation is used to unlock.

[0024] In one embodiment, as shown in FIG. 9, initially, the lock device 100 is in an unlocked state, the first clutch mechanism 40 is in an engaged state, and the second clutch mechanism 60 is in an engaged state. Specifically, the first drive surface C1 of the first drive part 42 abuts against the first clutch surface C2 of the first clutch part 44. The second drive surface D1 is far away from the second clutch surface D2, and the central angle between the two is about 180 degrees, i.e., a semicircle. The third drive surface A1 of the second drive part 62 abuts against the third clutch surface A2 of the second clutch part 64, and the fourth drive surface B1 is far away from the fourth clutch surface B2, and the central angle between the two is about 180 degrees, i.e., a semicircle.

[0025] When the operating member 52 is rotated in the unlocked state to lock it, as shown in FIG. 9a, a force is applied to rotate the operating member 52 counterclockwise by a certain angle (for example, 90 degrees), and the lock plug 32 in the operating member 52 rotates synchronously with the operating member 52. Since the third drive surface A1 and the third clutch surface A2 of the second clutch mechanism 60 are in contact with each other, the rotation of the operating member 52 drives the cylinder tailpiece 34 and the locking member 36 to rotate counterclockwise by a corresponding angle and reach the locking position. In this case, the locking member 36 is locked to the second object 220, and the lock device 100 is in the locked state. In the process, the operating member 52, the lock plug 32, the cylinder tailpiece 34, and the locking member 36 rotate synchronously, and the first clutch mechanism 40 and the second clutch mechanism 60 all remain in the engaged state. However, the rotation of the operating member 52 causes the return member 54 to be compressed or stretched, resulting in elastic deformation.

[0026] After the lock device 100 is locked with the operating member 52, when the operating member 52 is released, as shown in FIG. 9b, the return member 54 recovers from deformation, and the operating member 52 is driven to rotate in the reverse direction (i.e., clockwise) and return, so that the third drive surface A1 separates from the third clutch surface A2, and the second clutch mechanism 60 switches to the separated state. In this case, the central angle corresponding to the interval between the third drive surface A1 and the third clutch surface A2 is about 90 degrees. In the process of the automatic return of the operating member 52, the lock plug 32 returns in the reverse direction together with the operating member 52, and the cylinder tailpiece 34 and the locking member 36 remain stationary, while the cylinder tailpiece 34 and the lock plug 32 rotate relatively, and the first drive surface C1 separates from the first clutch surface C2, at which point the central angle corresponding to the interval between the two becomes larger than 90 degrees, and the first clutch mechanism 40 switches to the separated state.

[0027] When the lock device 100 needs to be unlocked, as shown in Fig. 9c, a key is inserted into the keyhole 321 of the lock plug 32, and the lock plug 32 is first driven by the key to rotate it in a second direction (i.e., clockwise) by a first angle (e.g., 90 degrees) so that the second drive surface D1 of the first drive unit 42 abuts against the second clutch surface D2 of the first clutch unit 44, and the first clutch mechanism 40 is switched to an engaged state. Then, as shown in Fig. 9d, the key is subsequently rotated in the second direction by a second angle (e.g., 90 degrees) so that the lock plug 32 drives the cylinder tailpiece 34 and the locking member 36 to rotate synchronously accordingly and reach the unlocked position. During this process, the operating member 52 remains stationary, while the cylinder tailpiece 34 and the locking member 36 rotate approximately 90 degrees relative to the operating member 52, returning the third drive surface A1 to a position in contact with the third clutch surface A2, and the second clutch mechanism 60 returns to the engaged state.

[0028] After unlocking, the lock device 100 allows the key to be removed. Before the key is removed, the key is rotated in a first direction, i.e., counterclockwise, by a certain angle, which is the sum of the first angle and the second angle, which is 180 degrees in this embodiment. The lock plug 32 rotates with the key, and the first drive part 42 is separated from the second clutch surface D2, and the first drive surface C1 returns to a state in which it is in contact with the first clutch surface C2, and the first clutch mechanism 40 returns to an engaged state. During this process, the operating member 52, the cylinder tailpiece 34, and the locking member 36 remain stationary, and the third drive surface A1 maintains a state in which it is in contact with the third clutch surface A2, i.e., the second clutch mechanism 60 maintains an engaged state, and the lock device 100 as a whole returns to the initial state shown in FIG. 9.

[0029] In addition, the lock device 100 can also be locked with a key in an unlocked state. In this case, the key is inserted into the keyhole 321 of the lock plug 32 and rotated counterclockwise, so that the first drive surface C1 of the first drive unit 42 drives and rotates the first clutch surface C2 of the first clutch unit 44, and further drives and rotates the cylinder tailpiece 34 and the locking member 36 counterclockwise to reach the locking position. In this process, the operating member 52 remains stationary, and the cylinder tailpiece 34 rotates relative to the operating member 52, the third drive surface A1 separates from the third clutch surface A2, and the second clutch mechanism 60 switches to a separated state. After the lock device 100 is locked with the key, the key can be directly pulled out, and the first clutch mechanism 40 remains in the engaged state.

[0030] In the case of the lock device 100 of the present application, by slightly adjusting its initial state, it is possible to realize locking by rotating it clockwise and unlocking by rotating it counterclockwise.

[0031] In the unlocked state, as shown in Fig. 9e, the first clutch mechanism 40 is in an engaged state, but the second drive surface D1 of the first drive unit 42 is adjusted to abut against the second clutch surface D2 of the first clutch unit 44, and the second clutch mechanism 60 is in an engaged state, but the fourth drive surface B1 of the second drive unit 62 is adjusted to abut against the fourth clutch surface B2 of the second clutch unit 64. The subsequent locking and unlocking processes are similar to those described above, and as shown in Fig. 9f, the fourth drive surface B1 of the second clutch mechanism 60 abuts against the fourth clutch surface B2 to realize keyless locking, and when unlocking with a key, the engagement state of the first clutch mechanism 40 switches to the abutment of the first drive surface C1 and the first clutch surface C2, which will not be repeated here.

[0032] In this embodiment, the cylinder tailpiece 34 includes a cylinder tailpiece body 341 and a first transmission member 343. The first transmission member 343 is generally cylindrical, and has a first connection hole 345 and a second connection hole 347 formed at both ends, respectively. The first connection hole 345 is used to connect the lock cylinder tailpiece body 341, and the second connection hole 347 is used to connect the locking member 36. Specifically, one end of the first transmission member 343 where the second connection hole 347 is provided extends to the outside of the lock housing 10, and the locking member 36 is detachably connected to the second connection hole 347 by a screw, a rivet, or the like. One end of the cylinder tailpiece body 341 is inserted into the first connection hole 345, and the two may be a clearance fit or an interference fit. In some embodiments, the cylinder tailpiece body 341 and the first transmission member 343 may be an integral structure.

[0033] A first clutch portion 44 is formed at the other end of the cylinder tailpiece body 341, and the first clutch portion 44 abuts against an end face of the lock plug 32. The second clutch portion 64 is disposed on one end face of the first transmission member 343 facing the lock plug 32, and extends outward in the axial direction from the first transmission member 343. In other embodiments, the second clutch portion 64 may be formed separately and then assembled to the first transmission member 343.

[0034] In another embodiment shown in Figures 10 and 10a, the cylinder tailpiece 34 comprises a cylinder tailpiece body 341 and a first transmission member 343 inserted and connected to the cylinder tailpiece body 341, the first clutch part 44 is disposed on the cylinder tailpiece body 341, and the second clutch part 64 is disposed on the first transmission member 343. The difference is that one end of the cylinder tailpiece body 341 extends outward after penetrating the first transmission member 343 and the lock housing 10, and is connected to a latch bolt, a lock device body, etc. via a transmission mechanism.

[0035] In this embodiment, the operating member 52 includes a knob 521 and a second transmission member 523. The knob 521 is a cylindrical structure with one open end and one closed end. The lock tube 56 and the lock plug 32 are disposed in the center of the inside of the knob 521. The closed end of the knob 521 is provided with a through hole 529 at the keyhole 321 position corresponding to the lock plug 32. The closed end of the knob 521 is provided with a plurality of connecting columns 525 extending toward the open end, and the second transmission member 523 is provided with a plurality of fixing holes 527 corresponding thereto. After a fixing member such as a screw passes through the fixing hole 527, it is screwed and fixed to the ram 525 such as a connecting column, thereby connecting the second transmission member 523 to the rotating knob 521. In some embodiments, the second transmission member 523 and the knob 521 may also be integrally formed.

[0036] In this embodiment, the lock tube 56 is assembled to the knob 521 after being molded separately, specifically, assembled to the space surrounded by the connecting columns 525. Preferably, the lock tube 56 is provided with a fitting portion 58 that protrudes between two adjacent connecting columns 525, so that the lock tube 56 and the knob 521 are restricted in the circumferential direction, and both can rotate synchronously after assembly. In some embodiments, the lock tube 56 and the knob 521 can also be molded integrally.

[0037] As shown in FIG. 5, the lock housing 10 includes the mounting seat 12 and the sleeve tube 14 extending outward from the center of the mounting seat 12 in a direction away from the operating member 52. The knob 521 is sleeved in the mounting seat 12, the second transmission member 523 is disposed in the mounting seat 12, the return member 54 is sleeved in the second transmission member 523, and the positioning portion 59 is disposed in the second transmission member 523 and the mounting seat 12. In this embodiment, as shown in FIG. 4 and FIG. 6, a step portion 121 is provided on the inner wall surface of one end of the mounting seat 12 facing the knob 521, and the second transmission member 523 is restricted in the axial direction, so that the second transmission member 523 cannot be separated from the lock housing 10, and further, the entire operating member 52 cannot be separated from the lock housing 10. Preferably, a bearing 16 is disposed between the mounting seat 12 and the second transmission member 523 to reduce friction when they rotate relative to each other. Preferably, a wear-resistant gasket 18 is disposed between the step 121 of the mounting seat 12 and the second transmission member 523 to further reduce wear.

[0038] The first transmission member 343 is disposed in the sleeve tube 14, and both ends thereof extend outside the sleeve tube 14, and the cylinder tailpiece 34 passes through the second transmission member 523 and is connected to the first transmission member 343. The second transmission member 523 surrounds the corresponding end of the first transmission member 343 and protrudes inward along a radial direction to form a second driving part 62, which is aligned with the second clutch part 64. In some embodiments, the second driving part 62 can also extend outward along an axial direction from the second transmission member 523. The second clutch part 64 can also extend outward along a radial direction from the first transmission member 343. Alternatively, if the second drive portion 62 has all of the second clutch portions 64 extending axially or all extending radially and both are located on the same ring, contact and separation can be achieved through relative rotation, and as a result, the second clutch mechanism 60 switches between the two states of separation and engagement.

[0039] The sleeve 14 preferably has a screw thread 19 formed on its periphery so that the lock device 100 can be installed by screwing it onto a first object 210, such as a door or window.

[0040] The lock device 100 of the present application can realize key lock and keyless lock through the setting of the first clutch mechanism 40 and the second clutch mechanism 60, which is more convenient to use. In addition, the second clutch mechanism 60 can be set to rotate counterclockwise to lock or rotate clockwise to lock by adjusting the state, so that the lock device 100 of the present application can be installed thereon and can operate normally without replacing parts regardless of whether the first object 210 is rotated left or right. Accordingly, the locking member 36 may have two states. As shown in the figure, the locking member 36 is a hook-shaped structure, and the hook direction can be left or right, which can be realized by flipping the locking member 36, which respectively adapts to two usage states of left opening and right opening. Overall, the structure is simple, the operation is convenient, and the versatility is good.

[0041] Please refer to FIG. 11. In one optional embodiment of the lock device, the lock device 100 may include a lock body 80, and the lock body 80 may be driven by, for example, a locking member 36. In this case, the locking member 36 may be a rod-like structure, one end of which is fixedly connected to the rotating second transmission member 523, and the other end of which is connected to the drive connection part 82 of the lock body 80. The lock device 100 is disposed on the first object 210, and drives and moves the cylinder tail piece 84 of the lock body 80 to lock it. In this embodiment, the cylinder tail piece 84 is called a deadbolt or a square bolt, etc., that is, the cylinder tail piece 84 does not have an inclined surface for a latch bolt structure, and when the lock device with a deadbolt is locked or unlocked, the control unit of the lock device must be operated to control the extension and retraction of the deadbolt. In contrast, when using a latch bolt structure, the latch bolt can generally be retracted simply by pressing an object against the inclined surface of the latch bolt perpendicular to the direction of extension of the latch bolt. Therefore, the deadbolt structure is safer than the latch bolt structure.

[0042] Please refer to Fig. 12. In one embodiment of the lock device, the lock device 100 includes a lock housing 10, a lock cylinder assembly 30 disposed in the lock housing 10, a thumbturn assembly 50 and a lock body 80 that are operatively connected to the lock cylinder assembly 30, and the thumbturn assembly 50 includes a first operating member 52 and a second knob 88, and the first operating member 52 includes the lock cylinder assembly 30 disposed on one side of a first object 110, and the second knob 88 is provided on the other side of the first object 110 via a fixed seat 86. The locking member 36 is a drive rod connected to the lock body 80, and the drive rod passes through a drive connection portion 82 of the lock body 80 and is operatively connected to the drive connection portion 82. In this embodiment, the drive rod 361 has a trapezoidal cross section, and the drive connection portion 82 is formed in a trapezoidal hole that roughly corresponds to this trapezoidal cross section, so that the rotation of the engaging member 36 can be transmitted to the lock body 80 by a connection that matches the shape of the drive connection portion 82.

[0043] In this embodiment, the drive connection part 82 of the lock body 80 has another setting state, and in this setting state, the drive connection part 82 is rotated 180 degrees to be arranged, and in this case, it is only necessary to rotate the locking member 36 and the first transmission member 343 by the same 180 degrees to be installed. For the rotation of the first transmission member 343 described above, an adjustment rod for auxiliary installation can be added, and the adjustment rod has an adjustment end part that matches the shape of the transmission member receiving opening of the first transmission member 343 and a thin rod part, and the adjustment end part can rotate by penetrating the drive connection part 82 of the lock body 80, and in this case, the thin rod part is not connected to the drive connection part 82 by transmission. As a result, the adjustment rod can be adjusted to a desired setting state by rotating the first transmission member 343.

[0044] Similar to the above-mentioned embodiment, a locking device having an additional setting state can be installed on the first object that opens to the left or right without replacing the locking device. Naturally, in order to clearly distinguish the two setting states, the first transmission member 343, the drive coupling portion 82 and the locking member 36 can be provided with identification for distinguishing the two installation states, so as to prevent assembly errors.

[0045] During assembly, first, the lock housing 10, the first transmission member 343, the cylinder tailpiece 31, the return member 54, the second transmission part 523, the locking sleeve 32, the first operating member 52, etc. are assembled in sequence and placed on the side of the first object 210 to be locked. The lock body 80 is embedded inside the first object 210 to be locked, and the cylinder tailpiece 84 of the lock body 80 is extendable relative to the first object 210. After that, the locking member 36 is inserted and penetrates the drive connection part 82 of the lock body 80, so that the locking member 36 penetrates the lock body 80 and is transmissively connected to the first transmission member 343. In this step, if the setting state of the first transmission member 343 needs to be adjusted, the first transmission member 343 can be adjusted using the adjustment rod. After the locking member 36 is inserted into a predetermined position, the fixed seat 86 and the second knob 88 can be sequentially attached to the other side of the first object 210. The second knob 88 has a receiving portion for receiving the locking member 36, and the receiving portion is transmission-matched with the locking member 36, so that the second knob 88 can control the locking and unlocking of the lock device. In this embodiment, the cylinder tailpiece of the lock body 80 is a deadbolt.

[0046] The above embodiments merely represent the preferred embodiments of the present application, and the description is relatively specific and detailed, but cannot be understood as limitations of the present application. It should be noted that those skilled in the art can make many modifications and improvements without departing from the idea of ​​the present application, such as combining different features in each embodiment, which are within the scope of protection of the present application.
