Description

TWO WAY LOCK AND LOCKER INCLUDING THE SAME

The present invention relates to a two way lock and a locker including the same, and more particularly, to a two way lock having an improved structure and a locker including the same.

Conventional locking apparatuses are largely classified to a wafer tumbler type and a pin tumbler type.

In a locking apparatus of the wafer tumbler type, when a key is not inserted to the locking apparatus, at least a part of a wafer is pushed by a spring to one side and protrudes to the outside of a plug. The protruded portion of the wafer prevents a rotation of the plug. When a suitable key is inserted, the wafer is positioned inside the plug and the rotation of the plug is possible.

The locking apparatus rotates in only one direction and performs only one operation (generally, a locking and unlocking operation). Thus, when various operations are necessary, since a plurality of locking apparatuses are necessary. Accordingly, the structure is complicate, the volume is large, and the appearance is deteriorated.

Meanwhile, an advertising paper is generally positioned at a locker including the locking apparatus to increase a use of the locker. The advertising paper is positioned inside a receiving portion having an opened one side at the locker. In this case, the advertising paper may be easily separated from the receiving portion, and thus, problems, like destruction and loss of the advertising paper, may arise.

An embodiment of the invention provides a two way lock being able to perform various operations with a simple structure.

Another embodiment of the invention provides a locker being able to increase an appearance, to enhance an advertising effect of an advertising board, and to prevent destruction and loss of the advertising paper.

According to an embodiment of the present invention, a two way lock performs a first operation through being rotated in a first direction by a first key and performs a second operation through being rotated in a second direction, opposite to the first direction, by a second key different from the first key.

The two way lock may includes an outer cylinder; a plug disposed inside the outer cylinder, wherein the first key and the second key are inserted into the plug; a plurality of wafers for controlling a rotation of the plug through a position change of at least one of the plurality of the wafers by at least one of the first key and the second key.

Each of the plurality of wafers may include a main body disposed inside the plug and a blocking protrusion protruding from the main body. The plug may include through holes where the blocking protrusion of the plurality of wafers penetrate, respectively. The outer cylinder may include a guide groove for the blocking protrusions of the plurality of wafers at an inner surface of the outer cylinder.

The plurality of wafers may include a first wafer, a second wafer, and a third wafer. The blocking protrusion of the first wafer may be disposed inside the plug when the second key is inserted, and the blocking protrusion of the first wafer may protrude through the through hole when the first key is inserted. The blocking protrusion of the second wafer may be disposed inside the plug when the first key is inserted, and the blocking protrusion of the second wafer may protrude through the through hole when the second key is inserted. The blocking protrusion of the third wafer may be disposed inside the plug when the first key is inserted and the second key is inserted.

The blocking protrusions of the first to third wafers may protrude through the through holes when another key other than the first key and the second key is inserted.

A number of the first wafer may be one, a number of the second wafer may be one, and the third wafer may include a plurality of third wafers.

The third wafer may be disposed between the first wafer and the second wafer.

The guide groove of the outer cylinder may include a main groove portion corresponding to the blocking protrusions; a first groove portion extended from the main groove portion to provide a rotation path in the first direction; and a second groove portion extended from the main groove portion to provide a rotation path in the second direction.

The first groove portion may be positioned to correspond to the first wafer, and the second groove portion may be positioned to correspond to the second wafer.

The blocking protrusions of the second and third wafers may move to an inside of the plug and the blocking protrusion of the first wafer may pass through the through hole and disposed in the first groove portion, when the first key is inserted.

The blocking protrusion of the first wafer may move along the rotation path of the first groove portion, when the first key is rotated in the first direction in a state that the first key is inserted.

The blocking protrusions of the first and third wafers may move to an inside of the plug and the blocking protrusion of the second wafer may pass through the through hole and disposed in the first groove portion, when the second key is inserted.

The blocking protrusion of the second wafer may move along the rotation path of the second groove portion, when the second key is rotated in the second direction in a state that the second key is inserted.

The two way lock may be installed at a locker having an advertising board. The first operation may include a fixing and separating operation of the advertising board. The second operation may include a locking and unlocking operation of the locker.

A locker according to an embodiment of the present invention includes the two way lock.

According to the embodiment, by fixing an advertising board to a frame or a locker by a locking apparatus, robbery, loss, destruction, and so on of the advertising board can be prevented. When the locking apparatus is rotated in the first direction by the first key, the advertising board can be easily separated and replaced from the frame or the locker. Also, by the locking apparatus, the locking and unlocking of the locker can be easily performed. In this state, when the frame is used for fixing the advertising board, the advertising board 30 can be firmly fixed and the advertising board can be stably protected.

The locking apparatus including the two way lock according to the embodiment can smoothly and easily perform the fixing and separating operation of the advertising board and the locking and unlocking operation of the locker by a simple structure. By controlling movement in the first and second direction through a structure and a shape of the wafers and the outer cylinder, the structure can be simplified and the volume can be minimized.

FIG. 1 is a perspective view of a locker according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the locker according to the embodiment of the present invention.

Referring to FIG. 1 and FIG. 2, a locker 100 according to an embodiment includes a main body 10, the frame 20 and an advertising board 30 installed at the main body 10, and a locking apparatus 40 for controlling at least one of a fixing and separating of the advertising board 30 and a locking and unlocking of the main body 10. Also, the locker 100 may further include a housing 50. The locking apparatus 40 is disposed inside the housing 50. This will be described in more detail.

The main body 10 may include a main body portion 12 having an inner space for storing various objects, and a door portion 14 for covering the main body portion 12. For the main body portion 12 and the door portion 14, various shapes, structures, materials, and so one may be applied.

The frame 20 is fixed to the main body 10 (more particularly, the door portion 14), and the advertising board 30 is fixed to the frame 20.

The frame 20 may have a structure being able to simplify a fixing and separating of the advertising board 30. Then, the advertising board 30 can be stably fixed to the main body 10, and can be easily replaced when it is necessary.

The frame 20 will be described in more detail with reference to FIG. 3 and FIG. 4. FIG. 3 is a front perspective view of the frame 20 of the locker 100 according to the embodiment of the present invention, and FIG. 4 is a back perspective view of the frame 20 of the locker 100 according to the embodiment of the present invention.

Referring to FIG. 3 and FIG. 4, the frame 20 includes a plate member 22 and a covering member 24. The plate member 22 has a plate shape and is fixed to the door portion 14. The covering member 24 is for opening and covering one side of the plate member 22.

A first fixing portion 22a is formed at one edge (for example, an upper edge) of the plate member 22. The first fixing portion 22a may include a plurality of first fixing portions 22a spaced from each other with regular intervals. A projection 222a is formed at one side of the first fixing portion 22a and another projection 222a is formed at the other side of the first fixing portion 22a opposite to the one side. The covering member 24 includes a second fixing portion 24a rotatably fixed to the first fixing portion 22a. The second fixing portion 24a may include a plurality of second fixing portions 24a spaced from each other with regular intervals. For example, the second fixing portion 24a may be positioned to correspond between adjacent two first fixing portions 22a among the plurality of the first fixing portions 22a. A groove 224a is formed at one side of the second fixing portion 24a and another groove 224a is formed at the other side of the second fixing portion 24a opposite to the one side. The plate member 22 and the covering member 24 can be rotatably fixed to each other by fixing the projections 222a of the first fixing portion 22a to the grooves 24a of the second fixing portion 24a.

The covering member 24 may include an extended portion 24b extending from the second fixing portion 24a to a front surface of the plate member 22 to cover the front surface of the plate member 22. Also, an advertising-board inserting groove 24c where the advertising board 30 is inserted may be formed between the second fixing portion 24a and the extended portion 24b or may be formed at the extended portion 24b. Also, a protruding supporter 22b may be formed at the other edge (for example, a lower edge) of the plate member 22. Accordingly, by fixing an upper edge of the advertising board 30 to the advertising-board inserting groove 24c and positioning a lower edge of the advertising board 30 on the protruding supporter 22b, the upper and lower edges of the advertising board 30 can be stably fixed.

Also, advertising-board insertion grooves (or holes) 22c where a part of the advertising board 30 is inserted are formed near edges of the plate member 22 where the covering member 24 is not positioned (that is, the upper edge and both side edges of the plate member 22). By inserting protrusion portions protruding from the advertising board 30 into the advertising-board insertion grooves 22c, the edges of the advertising board 30 can be entirely and stably fixed. In this state, the advertising-board insertion grooves 22c at the lower edge of the plate member 22 may be formed at the protruding supporter 22b. Thereby, the advertising-board insertion grooves 22c can be stably formed, and decrease in strength of the plate member 22 can be prevented.

The front surface of the plate member 22 (that is, the surface of the plate member 22 where the advertising board 30 is positioned and opposite to the main body 10) is a flat surface without additional elements and members so that the advertising board 30 can stably positioned. At a rear surface of the plate member 22 (that is, the surface of the plate member adjacent to the main body 10), a reinforcing member 24d for increasing the strength of the plate member 22 is formed. In the embodiment, it is illustrated that the reinforcing member 24d includes a plurality of reinforcing members 24d. Some of the plurality of reinforcing members 24a are formed in a horizontal direction, other of the plurality of reinforcing members 24a are formed in a vertical direction, and the other of the plurality of reinforcing members 24a are formed in a diagonal direction. By the reinforcing members 24d, the strength of the plate member 22 can increase, and thus, a thickness of the plate member 22 can decrease and unnecessary interference with the main body 10 can be prevented.

At the frame 20, an opening 26 exposing the housing 50 to the outside and a coupling hole (or coupling holes) 28 where a fixing member (not shown, for example, a screw, a bolt, and so on) for fixing with the main body 10 is positioned is formed. By coupling the fixing member to the coupling hole 28 in a state that the housing 50 is positioned inside the opening 26 of the frame 20, the frame 20 can be stably fixed to the main body 10 and the housing 50 can be exposed to the outside.

Referring to FIG. 1 and FIG. 2 again, the advertising board 30 may be a film or a sheet, or may have a planar shape. The advertising 30 has at least one of a phrase, a drawing, and so on for advertising an object, a service, and so on are shown. Various materials, such as, a resin, a metal, and so on may be used for the advertising board 30. An opening 32 and a protruded portion 34 are formed at the advertising board. The opening 32 correspond to the housing 50 and expose the housing 50 to the outside. The protruded portion 34 has a fixing groove (or fixing hole) 34a protruding to an inside of the opening 32. The protruded portion 34 having the fixing groove 34a is fixed by the locking apparatus 40 inside the housing 50. This will be described in more detail later.

The housing 50 that the locking apparatus 40 is positioned therein is fixed to the door portion 14 of the main body 10. The housing 50 contains or receives the locking apparatus 40 including a plurality of elements, and thus, the housing 50 including the locking apparatus 40 can be stably fixed to the door portion 14. A fixing groove (or hole) 52 where the protruded portion 34 of the advertising board 30 is inserted is formed at a side surface of the housing 50 (more particularly, an upper side surface of the housing 50).

The locking apparatus 40 fixes and separates the advertising board 30 of the main body 10, and locks and unlocks the main body 10. Particularly, in the embodiment, the locking apparatus 40 involves the fixing and separating of the advertising board 30. Thus, the advertising board 30 can be fixed and separated as needed. That is, in a normal state, the locking apparatus 40 stably fixes the advertising board 30 to the locker 100, and thus, the advertising board 30 can be prevented from being stolen and being separated from the locker 100 for fun or by mistake. Also, when the replacement of the advertising board 30 is necessary, the advertising board 30 can be easily separated from the locker 100 by unlocking the locking apparatus 40, and then, new advertising board 30 can be fixed to the locker 100 by locking the locking apparatus 40.

As such, in the embodiment, the locking apparatus 40 performs a first operation for the fixing and separating of the advertising board 30 and a second operation for the locking and unlocking of the locker 100. That is, the locking apparatus 40 performs two operations. The locking apparatus 40 will be described in more detail with reference to FIG. 5 to FIG. 8.

FIG. 5 is a perspective view of the locking apparatus 40 and the frame 30 of the locker 100 according to the embodiment of the present invention. FIG. 6 is an exploded perspective view of a two way lock 42 shown in FIG. 5, and FIG. 7 illustrates a state of a plug 420 and wafers 430 when a first key 60a is inserted and a second key 60b is inserted. FIG. 8 is a cross-sectional view illustrating each of portion A, portion B, portion C of an outer cylinder 410 shown in FIG. 7.

Referring to FIG. 5 to FIG. 8, the locking apparatus 40 includes a two way lock 42 operated in two directions, a first operating portion 44 performing an operation (a first operation) for the fixing and separating of the advertising board 30, and a second operating portion 46 performing another operation (a second operation) for the locking and unlocking of the locker 100.

The two way lock 42 is rotated in a first direction (for example, a right direction or a clockwise direction in the drawing) by the first key 60a, drives the first operating portion 44, and performs the first operation. The two way lock 42 is rotated in a second direction (for example, a left direction or a counterclockwise direction in the drawing) by the second key 60b, which is different from the first key 60a, drives the second operating portion 46, and performs the second operation.

The two way lock 420 may include an outer cylinder 410, a plug 420, and a plurality of wafers 430. The plug 420 is disposed inside the outer cylinder 410, and the first key 60a and/or the second key 60b is inserted into the plug 420. More particularly, a key hole (or a key-insertion hole 432a) of the plug 420 is the same for the first key 60a and the second key 60b, and one of the first key 60a and the second key 60b is inserted to the key hole as needed. The plurality of wafers 430 controls a rotation of the plug 420 through a position change of at least one of the plurality of the wafers 430 by at least one of the first key 60a and the second key 60b. Also, the two way lock 420 may further include a driving portion 440 having a guide member 442 and a protruded member 444 for driving the first and

second operating portions

44 and 46. The driving portion 440 may be formed at a lower portion (or an inner end) of the plug 420. However, the driving portion 440 may be not included as a member separated from the plug 420, and the driving portion 440 may be extended from the plug 420 so that the driving portion 440 and the plug 420 are integral with each other.

In this state, each of the wafers 430 includes a main body 432 disposed inside the plug 420 and a blocking protrusion 434 protruding from the main body 432. A key-insertion hole 432a where the first key 60a and/or second key 60b is inserted is formed at the main body 432, and projected portions 432b are formed at side surfaces of the main body 432. Since a spring 436 is positioned between the projected portions 432b and the plug 420, the blocking protrusion 434 of the wafer 430 can be maintained to penetrates through a through hole 422 of the plug 420 by the spring 436 when the first key 60a and the second key 60b are not inserted. When the first key 60a and/or the second key 60b is inserted into the key-insertion hole 432a of the wafer 430, some wafers 430 moves into an inside of the plug 420 according to shapes of the first key 60a and/or the second key 60b. This will be described in more detail later.

The through holes 422 where the blocking protrusions 434 penetrate are formed at the plug 420, and the guide groove 412 for the blocking protrusion 434, which penetrates the through hole 422 and protrudes to the outside, is formed at an inner surface of the outer cylinder 410.

In this state, the wafer 430 includes a first wafer 430a a second wafer 430b, and a third wafer 430c. The blocking protrusion 434 of the first wafer 430a moves to the inside of the plug 420 only by the second key 60b. The blocking protrusion 434 of the second wafer 430b moves to the inside of the plug 420 only by the first key 60a. The blocking protrusion 434 of the third wafer 430c moves to the inside of the plug 420 only by the first key 60a and the second key 60b. More particularly, as shown in (a) of FIG. 7, when the first key 60a is inserted, the blocking protrusions 434 of the second and

third wafers

430b and 430c move to the inside of the plug 420, and only the blocking protrusion 434 of the first wafer 430a passes through the through hole 422 of the plug 420 and protrudes to the outside. As shown in (b) of FIG. 7, when the second key 60b is inserted, the blocking protrusions 434 of the first and

third wafers

430a and 430c move to the inside of the plug 420, and only the blocking protrusion 434 of the second wafer 430b passes through the through hole 422 of the plug 420 and protrudes to the outside. When a key is not inserted or a key other than the first and

second keys

60a and 60b, the blocking protrusions of the first to

third wafer

430a, 430b, and 430c penetrate through the through hole 422 of the plug 420 and protrude to the outside.

In this state, a number of the first wafer 430a may be one, a number of the second wafer may be one, and the third wafer 430c may include a plurality of third wafers 430c. By increasing a number of the wafers 430, the two way lock 42 cannot be easily unlocked by a key other than the first and

second keys

60a and 60b. The third wafer 430c may be positioned between the first wafer 430a and the second wafer 430b.

The guide groove 412 for the blocking protrusions 434 of the wafers 430 are formed at the inner surface of the outer cylinder 410. In this state, the guide groove 412 may include a main groove portion 412a, a first groove portion 412b, and a second groove portion 412c. The main groove portion 412 corresponds to the blocking protrusions 434 of the plurality of wafers 430. The first groove portion 412b is extended from the main groove portion 412a to provide a rotation path in the first direction, and the second groove portion 412c is extended from the main groove portion 412a to provide a rotation path in the second direction. The first groove portion 412b is positioned to correspond to the first wafer 430a and provides the rotation path in the first direction, and the second groove portion 412c is positioned to correspond to the second wafer 430b and provides the rotation path in the second direction.

The driving portion 440 includes the guide member 442 and the protruded member 444. The guide member 442 drives the first operating portion 44 fixing a part of the advertising board 30. The protruded member 444 drives the second operating portion 46 for the locking and unlocking of the locker 100.

A fixing projection 44a is formed at an upper portion (or a front end portion) of the first operating portion 44. The fixing projection 44a is fixed to or hooked to the fixing groove 34a of the protruded portion 34 formed at the advertising board 30. A guide projection 44b is formed at a lower portion (or an inner end portion or a rear end portion) of the first operating portion 44. The guide projection 44b is guided by the guide member 442 of the driving portion 440. The guide member 422 includes a first portion 422a and a second portion 422b. The first portion 422a allows the first operating portion 44 to be positioned at a first position, and the second portion 422b allows the first operating portion 44 to be positioned at a second position that is far from the advertising board. A sliding portion 422c is positioned between the first portion 422a and the second portion 422b. The sliding portion 422c allows the first operation portion 44 to gradually move from the first position to the second position. The position change of the first operating portion 44 can be smoothly performed by the sliding portion 422c.

As shown in (a) of FIG. 9, when the plug 420 and the driving portion 440 are not rotated, the first operating portion 44 is fixed to the first portion 422a and is positioned at the first position (position 1 of FIG. 9). Since the fixing projection 44a is fixed to the fixing groove 34a, the protruded portion 34 of the advertising board 30 is positioned at the fixing groove 52 of the housing 50. Thus, the advertising board 30 can be stably fixed by the two way lock 42 or the locking apparatus 40. When the plug 420 and the driving portion 440 is rotated in the first direction by the first key 60a, the guide projection 44b moves to the second portion 422b via the sliding portion 422c. Then, as shown in (b) of FIG. 9, the first operating portion 44 is positioned at the second position (far from position 1 of FIG. 9 by a length L), and thus, the fixing projection 44a can be separated from the fixing groove 34a. That is, since the advertising board 30 is not fixed by the two way lock 42 or the locking apparatus 40, the advertising board 30 can be separated from the locking apparatus 40 and the locker 100.

Referring to FIG. 5 to FIG. 8 again, the second operating portion 46 may include a locking m ember 46a and a connecting portion 46b. The locking member 46a protrudes to an outside of the door portion 14 and is fixed to the main body portion 12. The connecting portion 46b protrudes from a side surface of the locking member 46a. The protruded member 444 where the connecting portion 46b is connected or is coupled when the plug 420 rotates in the second direction is formed at the two way lock 42 or the driving portion 440. The protruded member 444 pushes the connecting portion 46b and moves the locking member 46a when the plug 420 and the driving portion 440 rotates in the second direction. Then, the locking member 46a is positioned inside the housing 50.

When the plug 420 and the driving portion 440 does not rotate, the two way lock 42 does not apply force to the locking member 46a, and thus, the locking member 46a is maintained to protrude to an outside of the door portion 14. Then, the locking member 46a is positioned at both of the door portion 14 and the main body portion 12, and thus, the locker 100 is maintained to be locked. When the plug 420 and the driving portion 440 is rotated in the second direction by the second key 60b, the protruded member 444 pushes the connecting portion 46b and the locking member 46a moves inside the housing 50. Then, the locking member 46a is positioned at only the door portion 14, the main body portion 12 and the door portion 14 are not fixed to each other, and the locker 100 can be unlocked.

The locking apparatus 40 may include an additional locking member 48 for driving the second operating portion 46. The additional locking member 48 may include a keypad. The additional locking member 48 may drive the second operating portion 46 when predetermined password is entered by the keypad. The additional locking member 48 may directly drive the second operating portion 46, or may drive the second operating portion 46 by driving an additional element (additional elements). When the additional locking member 48 is applied, the locking and unlocking of the locker 100 can be possible although a user does not have the first and

second keys

60a and 60b. Thus, many and unspecified persons can use the locker 100, and a manager of the locker 100 having the first and

second keys

60a and 60b can manage the locker by using the two way lock 42. However, the present invention is not limited thereto, and thus, various modifications are possible.

An operation of the locker 100 will be described in detail.

When the first key 60a is inserted, as shown in (a) of FIG. 7, the blocking protrusions 434 of the second and

third wafers

430b and 430c move to the inside of the plug 420, and only the blocking protrusion 434 of the first wafer 430a passes through the through hole 422. When the first key 60a is rotated in the first direction (for example, the right direction or the clockwise direction in the drawing) in the state that the first key 60a is inserted, the blocking protrusion 434 of the first wafer 430a moves along the rotation path of the first groove portion 412b (shown in (a) of FIG. 8). Since the first groove portion 412b is extended along the path corresponding to the first direction, but is not extended along the path corresponding to the second direction, the first key 60a cannot be rotated in the second direction.

Thereby, the plug 420 is rotated in the first direction, the first operating portion 44 moves to the second portion 422b along the guide member 442 of the driving portion 440 and the first operating portion 44 is far from the advertising board 30. Then, the fixing projection 44a of the first operating portion 44 is separated from the fixing groove 34a of the advertising board 30. Thus, the advertising board 30 can be installed or separated.

On the other hand, when the second key 60b is inserted, as shown in (b) of FIG. 7, the blocking protrusions 434 of the first and

third wafers

430a and 430c move to the inside of the plug 420, and only the blocking protrusion 434 of the second wafer 430b passes through the through hole 422. When the second key 60b is rotated in the second direction (for example, the left direction or the counterclockwise direction) in the state that the second key 60b is inserted, the blocking protrusion 434 of the second wafer 430b moves along the rotation path of the second groove portion 412c (shown in (b) of FIG. 8). Since the second groove portion 412b is extended along the path corresponding to the second direction, but is not extended along the path corresponding to the first direction, the second key 60b cannot be rotated in the first direction.

Thereby, the plug 420 is rotated in the second direction, the protruded member 444 of the driving portion 440 pushes the connecting portion 46b of the second operating portion 46, and moves the locking member 46a to the inside of the housing 50. Thus, the locker 100 can be unlocked.

When the first key 60a and the second key 60b are not inserted or a key other than the first key 60a and the second key 60b is inserted, the blocking protrusions 434 of the first to

third wafers

430a, 430b, and 430c protrude to the outside through the through holes 422 of the plug 420. Thereby, the blocking protrusions 434 are fixed to the main groove portion 412a, and the movement in the first and second directions can be prevented.

According to the embodiment, by fixing the advertising board 30 to the frame 20 or the locker 100 by the locking apparatus 40, robbery, loss, destruction, and so on of the advertising board 30 can be prevented. When the locking apparatus 40 is rotated in the first direction by the first key 60a, the advertising board 30 can be easily separated and replaced from the frame 20 or the locker 100. Also, by the locking apparatus 40, the locking and unlocking of the locker 100 can be easily performed.

In this state, when the frame 20 is used for fixing the advertising board 30, the advertising board 30 can be firmly fixed and the advertising board 30 can be stably protected. An appearance of the locker 100 can be enhanced by the advertising board 30.

The locking apparatus 40 including the two way lock 42 can smoothly and easily perform the fixing and separating operation of the advertising board 30 and the locking and unlocking operation of the locker 100 by a simple structure. By controlling movement in the first and second direction through a structure and a shape of the wafers 430 and the outer cylinder 410, the structure can be simplified and the volume can be minimized.

In the embodiment, it is illustrated that the frame 20 is included. However, the present invention is not limited thereto, and thus, the frame 20 may be omitted. In the embodiment, it is illustrated that the two way lock 42 is applied to the locker 100. However, the present invention is not limited thereto, and thus, the two way lock 42 and the locking apparatus 40 including the same may be applied to various apparatuses other than the locker 100. Other modification may be possible.

Particular characteristics, structures, or effects described in connection with the embodiment are included in at least one embodiment of the present disclosure and not necessarily in all embodiments. Furthermore, the particular characteristics, structures, or effects of any specific embodiment of the present disclosure may be combined in any suitable manner with one or more other embodiments or may be changed by those skilled in the art to which the embodiments pertain. Therefore, it is to be understood that contents associated with such combination or change fall within the spirit and scope of the present disclosure.
