[0002] In the door lock market, whether it is a smart door lock or an ordinary door lock, in order to prevent criminals from using tools to pass through the peephole and open the door lock from the inside, an anti-peephole unlocking structure is usually set on the back panel of the door lock to increase the security level of the door lock.

[0003] The existing anti-peephole unlocking structure is mainly a mechanical anti-fool button structure, which usually has three forms: button toggle type, button press type, and button rotation type. These mechanical anti-fool button structures have the following problems: when in use, the user needs to lock the button of the anti-peephole unlocking structure inside the door, and the user must verify whether the anti-peephole button is locked every time. If the button is not locked due to human factors, the anti-peephole unlocking structure cannot be activated; when opening the door lock from the inside, the user needs to unlock the button from the inside before opening the door, which makes the action cumbersome and inconvenient to use; when there is no one inside the door, the button cannot be locked, so the anti-peephole unlocking structure cannot be activated.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The handle device for preventing cat's eye unlocking provided by the present invention comprises a handle, a handle linkage and a clutch mechanism, wherein a pressure sensor for detecting pressing force is arranged in the handle, the handle linkage is connected to the handle and moves with the movement of the handle, the clutch end of the clutch mechanism is used for clutch limit cooperation with the handle linkage, the drive controller of the clutch mechanism is connected to the pressure sensor, when the pressure sensor detects the pressing force on the handle, a pressure signal is generated, the drive controller receives the pressure signal sent by the pressure sensor, and controls the action of the clutch mechanism according to the pressure signal, so that the clutch end and the handle linkage are disengaged from the limit cooperation, allowing the handle to perform unlocking movement; when the handle is reset to the locked position, the drive controller controls the clutch end to reset to the limit cooperation position with the handle linkage.

[0037] When working, the initial position of the handle is in the locked position. At this time, the clutch end of the clutch mechanism cooperates with the handle linkage to limit the movement of the handle linkage, thereby limiting the opening movement of the handle. When the person indoors holds the handle with his hand and opens it, the pressure sensor in the handle detects the pressure of the hand and sends a pressure signal to the drive controller of the clutch mechanism. After receiving the pressure signal, the drive controller controls the clutch mechanism to move so that the clutch end and the handle linkage are out of the limit position. At this time, the handle linkage can move, thereby allowing the handle to unlock. The person indoors uses his hand to switch the handle to the unlocking position, and the door lock opens. When the person indoors lets go, the handle is reset to the locked position under the action of its own reset structure, and the drive controller of the clutch mechanism controls the clutch end to reset to the limit position with the handle linkage, and the handle is restricted from opening again.

[0038] It can be seen that the handle device can only open when the hand of the person in the room is holding it and the pressure sensor detects the pressure of the hand. When the hand releases the handle and the handle returns to the locked state, the opening action of the handle is restricted again and the door lock cannot be opened, thereby preventing the situation where the criminals use tools to reach into the door through the cat's eye to open the handle. Compared with the existing anti-cat's eye unlocking structure, the anti-cat's eye unlocking handle device in this application only needs to be held by hand to perform the unlocking action. After releasing the hand, the handle is automatically restricted from moving. There is no need to unlock the anti-cat's eye unlocking button every time, nor is it necessary to manually lock the anti-cat's eye button after each unlocking. There is no need to verify whether the anti-cat's eye button is locked every time, and there will be no situation where the anti-cat's eye unlocking structure is forgotten to be opened manually. This avoids the situation where the anti-cat's eye unlocking structure is not activated due to human factors, improves safety, and is convenient to use.

[0039] The door lock provided by the present invention adopts the handle device of the present invention, and therefore has the same technical effect, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0057] The core of the invention is to provide a handle device which can prevent the lock from being opened through a cat's eye, which is convenient to use and improves safety.

[0058] The invention also provides a door lock comprising the handle device, which is convenient to use and improves safety.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Please refer to Figure 1-Figure 15 The embodiment of the present invention provides a handle device for preventing cat's eye unlocking, hereinafter referred to as the handle device, which includes a handle 1, a handle linkage 3 and a clutch mechanism 7; wherein a pressure sensor 6 for detecting pressing force is provided in the handle 1, and the pressure sensor can be a capacitive pressure sensor; the handle linkage 3 is linked to the handle 1 and moves with the movement of the handle 1; the clutch end 72 of the clutch mechanism 7 is used for clutching and limiting cooperation with the handle linkage 3, and the drive controller of the clutch mechanism 7 is connected to the pressure sensor 6. When the pressure sensor 6 detects the pressing force on the handle 1, the drive controller receives the pressure signal sent by the pressure sensor 6, and controls the clutch mechanism 7 to operate, so that the clutch end 72 and the handle linkage 3 are disengaged from the limiting cooperation, allowing the handle 1 to perform an unlocking movement. When the handle 1 is reset to the locked position, the drive controller controls the clutch end 72 to reset to the limiting cooperation position with the handle linkage 3.

[0061] The working principle and working process of the handle device are as follows:

[0062] Before unlocking, the initial position of the handle 1 is in the locked position. At this time, the clutch end 72 of the clutch mechanism 7 cooperates with the handle linkage 3 to limit the movement of the handle linkage 3, thereby limiting the handle 1 from unlocking. When unlocking, the person in the room holds the handle 1 with his hand, and the pressure sensor 6 in the handle 1 detects the pressure of the hand. The pressure sensor 6 sends a pressure signal to the drive controller of the clutch mechanism 7. After receiving the pressure signal, the drive controller controls the clutch mechanism 7 to move, so that the clutch end 72 and the handle linkage 3 are out of the limit position. At this time, the handle linkage 3 can move, thereby allowing the handle 1 to unlock. The person in the room switches the handle 1 to the unlocking position by hand, and the door lock is opened.

[0063] When the person indoors lets go, the handle 1 is reset to the locked position under the action of its own reset structure, and the drive controller of the clutch mechanism 7 controls the clutch end 72 to reset to the limit matching position with the handle linkage member 3, and restricts the handle 1 from unlocking again.

[0064] It can be seen that the handle device can only unlock the door when the hand of the person in the room is holding the handle 1 and the pressure sensor 6 detects the pressure of the hand. When the hand releases the handle 1 and the handle 1 returns to the locked state, the unlocking action of the handle 1 is restricted again and the door lock cannot be opened, thereby preventing the situation where the criminals use tools to reach into the door through the cat's eye to open the handle 1. Compared with the existing anti-cat's eye unlocking structure, the handle device in the present application only needs to hold the handle 1 by hand to release the anti-cat's eye unlocking function and perform the unlocking action. After releasing the hand, the anti-cat's eye unlocking function is automatically activated, and the handle 1 is automatically restricted from unlocking. There is no need to unlock the anti-cat's eye unlocking button first each time, nor is it necessary to manually lock the anti-cat's eye button after each unlocking. There is no need to verify whether the anti-cat's eye button is locked each time, and there will be no situation where the anti-cat's eye unlocking structure is forgotten to be opened manually. This avoids the situation where the anti-cat's eye unlocking structure is not activated due to human factors, improves safety, and is convenient and quick to unlock.

[0065] The present embodiment provides a clutch mechanism 7, which includes a shell 71, a motor 73 and a linear motion output component 75; wherein the shell 71 is preferably composed of an inner shell and an outer shell, the inner shell is located on the inner side of the indoor surface shell 2, and the outer shell is close to the outer side of the indoor surface shell 2; the motor 73 is arranged in the shell 71, and the drive controller is a motor controller, that is, the drive controller is integrated with the motor 73. Of course, the drive controller can also be separately arranged from the motor 73, and the motor controller receives the pressure signal of the pressure sensor 6 and controls the operation of the motor 73; the linear motion output component 75 is arranged in the shell 71, and the linear motion output component 75 has a rotating end and a linear motion end. The output shaft of the motor 73 is transmission-connected to the rotating end of the linear motion output component 75, and the linear motion output component 75 converts the rotation of the rotating end into a linear motion output of the linear motion end of the linear motion output component 75, and the linear motion end is the clutch end 72.

[0066] The working principle of the clutch mechanism 7 is as follows: when the pressure sensor 6 detects the hand pressure acting on the handle, it sends a pressure signal to the motor controller. After receiving the pressure signal, the motor controller controls the motor 73 to rotate. The output shaft of the motor 73 drives the rotating end of the linear motion output component 75 to rotate. The linear motion output component 75 converts the rotation of the rotating end into the linear motion of the linear motion end. The linear motion end acts as the clutch end 72, and moves from the initial position of the limit match with the handle linkage 3 to the position of disengagement from the limit match. At this time, the handle 1 can be unlocked. When the handle 1 is reset to the locked position, the motor controller controls the motor 73 to rotate in the opposite direction, driving the linear motion end to reset to the position of the limit match with the handle linkage 3, and the handle 1 cannot be unlocked.

[0067] like Figure 6-Figure 9As shown, further, this embodiment provides a specific linear motion output assembly 75, which includes a clutch shaft 751, a coil spring 753 and a clutch actuator 752; wherein the clutch shaft 751 is drivingly connected to the output shaft of the motor 73, and a push rod 7511 is radially arranged on the outer periphery of the clutch shaft 751, and the clutch shaft 751 is a rotating end; the coil spring 753 is sleeved on the clutch shaft 751, and the push rod 7511 is inserted into the spiral gap of the coil spring 753; the clutch shaft 751 is inserted into the clutch actuator 752, The clutch shaft 751 rotates relative to the clutch actuator 752. The clutch actuator 752 is provided with a guide structure 7521 for circumferential limitation and linear guidance. The clutch actuator 752 cooperates with the shell 71 in a linear guidance through the guide structure 7521. The clutch actuator 752 can only move in a straight line and cannot rotate. It serves as a linear motion end, and one end of the clutch actuator 752 is the clutch end 72. The two ends of the coil spring 73 are respectively fixed on the clutch actuator 752, and the coil spring 73 and the clutch actuator 752 are relatively stationary in the circumferential direction.

[0068] The working principle and working process of the linear motion output assembly 75 are as follows:

[0069] The motor 73 drives the clutch shaft 751 to rotate. Since the clutch shaft 751 is axially positioned and immovable, the push rod 7511 is inserted into the spiral gap of the spiral spring 753. The push rod 7511 rotates with the clutch shaft 751. The push rod 7511 is guided to move in the spiral gap. Since the spiral spring 753 and the clutch actuator 752 are fixed and circumferentially limited, the push rod 7511 cooperates with the spiral spring 753. The rotation of the push rod 7511 drives the spiral spring 753 and the clutch actuator 752 to move along a straight line. When the pressure sensor 6 detects the pressure of the hand, the motor 73 finally drives the clutch actuator 752 to move in a direction so that the clutch end 72 of the clutch actuator 752 and the handle linkage 3 are out of the limit fit; when the hand releases the handle 1, after the handle 1 returns to the locked position, the motor 73 rotates in the opposite direction, and finally drives the clutch actuator 752 to return to the limit fit position.

[0070] Of course, the linear motion output assembly 75 can also be other structural forms. In the present embodiment, the linear motion output assembly 75 can be a screw matching structure. Specifically, the linear motion output assembly 75 includes a screw and a thread sleeve. The screw and the thread sleeve are matched and sleeved. The screw serves as a rotating end, and the thread sleeve serves as a linear motion end. The screw is connected to the motor 73 in a transmission manner. The thread sleeve is circumferentially limited and can only move in a straight line. Therefore, the motor 73 drives the screw to rotate. Since the screw and the thread sleeve are connected through a thread groove, the thread sleeve is circumferentially limited. Therefore, the screw drives the thread sleeve to move in a straight line, and the clutch end of the thread sleeve is clutched and limited with the handle linkage 3.

[0071] Furthermore, if Figure 6-Figure 9As shown, in this embodiment, the clutch mechanism 7 further includes a transmission assembly 74, and the output shaft of the motor 73 is transmission-connected to the rotating end of the linear motion output assembly 75 through the transmission assembly 74. The output shaft of the motor 73 is transmission-connected to the rotating end of the linear motion output assembly 75 at a certain transmission ratio through the transmission assembly 74. Of course, the transmission assembly 74 may not be provided, but the output shaft of the motor 73 may be directly connected to the rotating end.

[0072] As an optimization, in this embodiment, the transmission assembly 74 is a gear set, a synchronous belt transmission assembly or a chain transmission assembly. It is preferred to use a gear set for transmission connection, which has the advantages of compact structure and high transmission accuracy. The gear set is composed of at least two gears, and the specific number is not limited. The gear set can achieve multi-stage reduction such as primary, secondary, and tertiary speed reduction, depending on the actual situation.

[0073] like Figure 6 , Figure 8 , Figure 10-11 As shown, in this embodiment, the handle device also includes a mechanical clutch mechanism 4, which is used to complete the manual unlocking of the anti-cat-eye function through the mechanical clutch mechanism 4 when the motor 73 of the clutch mechanism 7 fails. Specifically, the mechanical clutch mechanism 4 includes a clutch mechanical part 42 and a sliding switch 41; wherein the clutch mechanical part 42 is parallel to the moving direction of the clutch actuator 752, and when the clutch mechanical part 42 drives the clutch actuator 752 to move in the direction of disengaging from the limit fit, the clutch actuator 752 moves to the side away from the handle linkage part 3; the sliding switch 41 is arranged on the housing 71 in a direction parallel to the moving direction of the clutch actuator 42, and the sliding switch 41 is connected to the clutch mechanical part 42, and the sliding switch 41 moves synchronously with the clutch mechanical part 42.

[0074] The working principle and working process of the mechanical clutch mechanism 4 are as follows: when the motor 73 of the clutch mechanism 7 cannot rotate, at this time, Fig.11 As shown, the clutch end 72 of the clutch mechanism 7 and the handle linkage member 3 are in a limited position matching state, and the handle 1 cannot be unlocked. At the same time, the clutch mechanical member 42 and the sliding switch 41 of the mechanical clutch mechanism 4 are both in the anti-peephole locking position where the clutch end 72 and the handle linkage member 3 are limited position matching. At this time, the sliding switch 41 is moved to the anti-peephole unlocking position, the sliding switch 41 drives the clutch mechanical member 42 to move, and the clutch mechanical member 42 drives the clutch actuator 752 to move in the direction of disengaging from the limited position matching, as shown in FIG. Fig.10 As shown, the clutch actuator 752 is disengaged from the limit fit with the handle linkage 3, and the handle 1 can be unlocked. In this process, since the clutch shaft 751 is restricted by the motor 73 and cannot rotate, when the clutch actuator 752 moves in a straight line away from the handle linkage 3, the coil spring 753 is compressed by the push rod 7511 to accumulate elastic force.

[0075] Furthermore, in the present embodiment, when the clutch mechanical component 42 moves toward the side close to the handle linkage component 3, that is, when it moves toward the direction of the limit fit, the clutch mechanical component 42 and the clutch actuator 752 are disengaged, that is, the clutch mechanical component 42 and the clutch actuator 752 are not fixedly connected, but contact-connected. Only when the clutch mechanical component 42 moves toward the direction of disengagement from the limit fit, the clutch mechanical component 42 is contact-connected with the clutch actuator 752, pushing the clutch actuator 752 to move in the direction of disengagement from the limit fit.

[0076] When the slide switch 41 moves from the anti-peephole unlocking position to the anti-peephole locking position, the slide switch 41 drives the clutch mechanism 42 to return to the initial position. At this time, the clutch actuator 752 is no longer pushed by the clutch mechanism 42, and the coil spring 753 accumulates elastic force. Therefore, the clutch actuator 752 is reset to the position of the handle linkage member 3 under the elastic force of the coil spring 753, and the handle 1 is restricted from unlocking again.

[0077] The purpose of non-fixedly connecting the clutch mechanical part 42 and the clutch actuator 752 is to separate the movements of the clutch mechanism 7 and the mechanical clutch mechanism 4 so that they can independently complete their respective anti-peephole unlocking and locking functions.

[0078] Of course, in this embodiment, the clutch mechanical component 42 and the clutch actuator 752 can also be fixedly connected, and the clutch mechanical component 42 and the clutch actuator 752 act synchronously regardless of the process of unlocking and locking the anti-peephole.

[0079] Furthermore, in this embodiment, the mechanical clutch mechanism 4 further includes a reset elastic member 43, the two ends of which act on the clutch mechanical member 42 and the housing 71 respectively, and apply an elastic reset force to the clutch mechanical member 42 to move toward the side close to the handle linkage member 3. The purpose of setting the reset elastic member 43 is that when the sliding switch 41 moves from the anti-cathole locking position to the anti-cathole unlocking position, the clutch mechanical member 42 compresses the reset elastic member 43, and the reset elastic member 43 accumulates an elastic reset force. When the sliding switch 41 is released, under the action of the reset elastic force of the reset elastic member 43, the sliding switch 41 automatically resets from the anti-cathole unlocking position to the anti-cathole locking position. The elastic reset member 43 is preferably a compression spring.

[0080] like Figure 1-Figure 4 As shown, this embodiment provides a specific handle device, wherein the handle 1 is a rotating handle 11, and the rotating handle 11 is rotatably connected to the indoor surface shell 2 around a horizontal rotation axis perpendicular to the indoor surface shell 2 of the door lock. When the rotating handle 11 is in a horizontal state, the rotating handle 11 is in an initial locking position, and the hand holds the rotating handle 11 and rotates it downward to perform an unlocking action.

[0081] In this embodiment, when the handle 1 is a rotating handle 11, the handle linkage member 3 is a handle steering member 31, which is coaxially arranged with the horizontal rotation axis of the rotating handle 11, and is provided with a limit groove 311 which cooperates with the clutch end 72 for clutch limiting.

[0082] like Figure 3 As shown, when the rotating handle 11 is in a horizontal state, the limiting groove 311 faces the clutch end 72 of the clutch mechanism 7. When the clutch end 72 is embedded in the limiting groove 311, the clutch end 72 limits the rotation of the handle steering member 31, thereby limiting the rotation of the rotating handle 11.

[0083] like Figure 4 As shown, when the clutch end 72 is disengaged from the limiting groove 311, the handle steering member 31 can rotate, so that the handle 1 can be unlocked.

[0084] Furthermore, in this embodiment, the clutch mechanism 7 further includes a steering limit plate 8 connected to the clutch end 72, and the clutch end 72 is engaged and limited with the limit groove 311 through the steering limit plate 8. The clutch end 72 drives the steering limit plate 8 to move linearly, such as Figure 3 As shown, when the steering limiting plate 8 is embedded in the limiting groove 311 , the steering limiting plate 8 limits the rotation of the handle steering member 31 , thereby limiting the rotation of the rotating handle 1 .

[0085] like Figure 4 As shown, when the steering limiting plate 8 is disengaged from the limiting groove 311, the handle steering member 31 can rotate, so that the handle 1 can be unlocked.

[0086] Of course, the clutch end 72 of the clutch mechanism 7 can also be directly set as a stud, and the stud and the limiting groove 311 can be clutched and limited.

[0087] like Figure 1 and Figure 2 In this embodiment, the rotating handle 11 includes a handle body 111 and a handle cover 112, and the pressure sensor 6 is disposed in the handle body 111 and is disposed along a position that can be touched by a user. According to the normal posture of holding the rotating handle 11, the pressure sensor 6 is preferably disposed at a position where the thumb can press. Of course, the pressure sensor 6 can also be disposed at other positions of the handle body 111, for example, at the position where the user holds the rotating handle 11, as long as the hand pressing pressure can be felt.

[0088] Alternatively, the pressure sensor 6 is disposed in the mounting groove of the handle cover 112, and a pressure-deformed gap is provided between the pressure sensor 6 and the handle cover 112. Since the pressure sensor 6 is a capacitive pressure sensor, the handle cover 112 is deformed by pressure, and the capacitance changes by changing the gap size, thereby detecting a pressure signal.

[0089] In order to protect the pressure sensor 6 , in the present embodiment, the pressure sensor 6 is disposed in a support sleeve, and the pressure sensor 6 is installed in the rotating handle 11 through the support sleeve.

[0090] like Figure 12-Figure 15 This embodiment provides another handle device, wherein the handle 1 is a push-pull handle 12, and the push-pull handle 12 is connected to the indoor surface shell 2 by swinging around a horizontal swing axis parallel to the indoor surface shell 2 of the door lock. The unlocking and locking operations of the door lock are realized by pushing the push-pull handle 12 inward or pulling the push-pull handle 12 outward. The relationship between the push-pull action of the push-pull handle 12 and the unlocking and locking is determined according to the door opening direction. Usually, when the door is opened outward, pushing the push-pull handle 12 is an unlocking action, and when the push-pull handle 12 is in a vertical position, the door lock is in a locked state.

[0091] In this embodiment, when the handle 1 is a push-pull handle 12, the handle linkage 3 is a sliding plate 32, and the sliding plate 32 is slidably set in the indoor surface shell 2. The sliding plate 32 is connected to the toggle end of the push-pull handle 12. The push-pull handle 12 drives the sliding plate 32 to slide in the indoor surface shell 2. The sliding plate 32 is provided with a limit notch 321 for clutch limit cooperation with the clutch end 72.

[0092] The working principle of the handle device is as follows: taking the unlocking action of pushing the push-pull handle 12 as an example, when the push-pull handle 12 is in a vertical position, the door lock is in a locked state. Fig.14 As shown, the clutch end 72 of the clutch mechanism 7 is limitedly matched with the limiting notch 321 of the sliding plate 32, and the sliding plate 32 cannot slide up and down in the indoor shell 2. Since the sliding plate 32 limits the toggle end of the push-pull handle 12, the push-pull handle 12 cannot be pushed to unlock. Fig.15 As shown, the sliding plate 32 can slide up and down in the indoor shell 2, and at this time, the push-pull handle 12 can be pushed, and the toggle end of the push-pull handle 12 toggle the sliding plate 32 to slide in the indoor shell 2. Since a rack is provided on the sliding plate 32, the rack moves linearly, driving the gear connected to the lock body to rotate, thereby realizing the unlocking operation. When the push-pull handle 12 is reset to the vertical position under the action of its own reset structure, the clutch end 72 of the clutch mechanism 7 is reset to the position of limiting the limit notch 321, and the push-pull handle 12 is again limited to push the unlocking.

[0093] Further, in this embodiment, the clutch end 72 that cooperates with the limiting notch 321 is a limiting stud.

[0094] In this embodiment, a pressure sensor 6 is provided on the inner or outer side of a side panel of the push-pull handle 12 close to the indoor surface shell 2. As long as it is a position that can be touched by a user's finger, the pressure sensor 6 is preferably arranged at a position that can be pressed by a finger according to the normal posture of holding the push-pull handle 12.

[0095] The above two types of handle devices can both apply the clutch mechanism 7 and the mechanical clutch mechanism 4 of the present invention, and components of suitable shapes and sizes can be selected according to the specific space, as long as the principles are the same.

[0096] Based on the handle device described in any of the above embodiments, an embodiment of the present invention further provides a door lock, which includes a lock body 5 and a handle device, and the handle device is the handle device described in any of the above embodiments.

[0097] Since the door lock adopts the handle device of the present invention, the handle 1 can only be unlocked when the hand of the person in the room is holding the handle 1 and the pressure sensor 6 detects the pressure of the hand. When the hand releases the handle 1 and the handle 1 returns to the locked state, the unlocking action of the handle 1 is restricted again and the door lock cannot be opened, thereby avoiding the situation that the criminals use tools to reach into the door through the cat's eye to open the handle 1. Compared with the existing door locks with anti-cat's eye unlocking structure, the door lock in the present application only needs to hold the handle 1 by hand to release the anti-cat's eye unlocking function and perform the unlocking action. After releasing the hand, the anti-cat's eye unlocking function is automatically activated, and the handle 1 is automatically restricted from unlocking. There is no need to unlock the anti-cat's eye unlocking button first each time, nor is it necessary to manually lock the anti-cat's eye button after each unlocking. There is no need to verify whether the anti-cat's eye button is locked each time, and there will be no situation where the anti-cat's eye unlocking structure is forgotten to be opened manually. This avoids the situation that the anti-cat's eye unlocking structure is not activated due to human factors, improves safety, and is convenient and quick to unlock.

[0098] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0099] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
