- the seatback member 16 is linked to the seat support frame 22 using a first seatback member linkage set 50 and a second seatback member linkage set (not visible in this view). Due to the first seatback member linkage set 50 , as the seatback member 16 rotates rearwardly, the seat support frame 22 is displaced forwardly.
- a zero gravity position for furniture member 10 is defined when the seatback member 16 is positioned in a fully reclined position (shown) by rotation about the seatback member direction of rotation “B”, the base member 12 is positioned in its fully rearward rotated position by rotation with respect to the base member direction of rotation “A”, and when the leg rest assembly 24 is in its fully extended position.

- each of the first and second seatback member linkage sets 50 , 68 are also connected to the seat support frame 22 such that rotation of the seatback member 16 also displaces seat support frame 22 in a generally forward or rearward direction with respect to an occupant of the furniture member 10 .
- a DC drive motor 72 is provided which is located at a forward end of the support frame 14 . Operation of the drive motor 72 causes axial rotation of a drive rod 74 with respect to a longitudinal axis of the drive rod 74 .
- Drive rod 74 is oriented substantially parallel to the first torque tube 70 .
- First and second support arms 76 a , 76 b are rotatably connected to the drive rod 74 and further connected to a support arm 76 positioned at a forward end of base member 12 , and also oriented substantially parallel to first torque tube 70 .
- the first and second pantograph linkage sets 28 , 34 are both rotatably connected to each of the drive rod 74 and the support rod 78 , providing support for the leg rest assembly 24 in either the fully stowed or the fully extended positions.
- a positioning motor 80 connected to a gear housing 82 is located proximate to leg rest drive motor 72 .
- a gear assembly such as a worm gear (not shown) within gear housing 82 is rotated by operation of positioning motor 80 .
- a slide member 84 is slidably disposed with respect to gear housing 82 and connected to the gear assembly within gear housing 82 . Rotation of the gear assembly within gear housing 82 with respect to a longitudinal axis of the gear housing 82 thereby causes either a forward or rearward displacement of the slide member 84 with respect to gear housing 82 .
- First and second connecting plates 86 a , 86 b are rotatably connected to the slide member 84 and are fixed with respect to a second torque tube 88 .
- Second torque tube 88 is also oriented substantially parallel with respect to first torque tube 70 .
- Second torque tube 88 is fixed at opposite ends to each of the first and second arm rest portions 18 , 20 .
- the longitudinal displacement of slide member 84 with respect to gear housing 82 thereby causes rotation of the base member 12 with respect to base member axis of rotation 48 as described in reference to FIGS. 4-7 , as well as rotation of the seatback member 16 , as will be further described herein.
- the slide member 84 is also connected to each of a first connecting arm 90 and a second connecting arm 92 which are positioned on and rotatably connected to opposite sides of the slide member 84 .
- the first and second connecting arms 90 , 92 are each individually rotatably connected to one of a first or a second connecting link 94 a , 94 b which are both connected to the first torque tube 70 .
- Linear displacement of the slide member 84 is thereby linked to the first torque tube 70 , displacing first torque tube 70 and thereby providing motive force for rotation of seatback member 16 .
- the extension of the first and second pantograph linkage sets 28 , 34 is accomplished by operation of drive motor 72 .
- the support rod 78 is slidably displaced in a forward direction with respect to support rod containment members 96 connected to opposite sides of the seat support frame 22 .
- Rotation of drive rod 74 about its central longitudinal axis, as well as forward displacement of the support rod 78 thereby provides for full extension of the link members of first and second pantograph linkage sets 28 , 34 .
- Positioning motor 80 is not operated during the extension or retraction of the leg rest assembly 24 ; therefore, slide member 84 displacement is not required for extension or retraction of the leg rest assembly 24 .
- Axial rotation of the drive rod 74 also causes a forward rotation of each of a first and a second motion link 98 a , 98 b which are connected to the support rod 78 such that rotation of the first and second motion links 98 a , 98 b produces the forward displacement of support rod 78 .
- leg rest drive motor 72 is not operated and positioning motor 80 is electrically operated. Operation of positioning motor 80 causes a forward sliding displacement motion of slide member 84 . Because the first and second connecting plates 86 a , 86 b are connected to both the slide member 84 and to the second torque tube 88 , the forward sliding motion of slide member 84 directly forwardly displaces the second torque tube 88 and, by its connection to each of the first and second connecting arms 90 , 92 , the first torque tube 70 is also pulled forward.
- leg rest assembly 24 when the furniture member 10 is positioned in the furniture member fully rearward rotated position, the leg rest assembly 24 , including each of the first and second pantograph linkage sets 28 , 34 , can be extended to their fully extended position by operation of drive motor 72 .
- This operation of drive motor 72 is independent of any operation of the positioning motor 80 and therefore allows complete independent operation of leg rest assembly 24 .
- slide member 84 can slide in either a forward or a rearward direction with respect to gear housing 82 by operation of positioning motor 80 in either of a forward or a rearward operational direction.
- these members are rotatably connected to the slide member 84 using a slide member connecting shaft 100 .
- the axial sliding motion of slide member 84 is therefore accommodated by the rotational connection between slide member connecting shaft 100 and each of the first and second connecting arms 90 , 92 , which also allows for the upward and downward rotation of gear housing 82 as slide member 84 axially displaces.
- positioning motor 80 is operated which rotates a gear assembly (not shown) within a gear drive assembly 102 , thereby axially displacing the slide member 84 on gear housing 82 in a rearward and upward displacement direction “D”.
- the positioning motor 80 and the gear drive assembly 102 are together rotatably connected to the front cross tube 58 by a clevis 104 extending from the gear drive assembly 102 which is rotatably connected to a U-bracket 106 using a clevis pin 108 .
- the U-bracket 106 is fixed to the front cross tube 58 such that the clevis pin 108 defines a motor axis of rotation 110 . Rearward displacement of the slide member 84 and consequent rearward displacement of the first and second connecting arms 90 , 92 thereby force rotation of the seat support frame 22 and the base member 12 in a forward or lift direction of rotation “C” with respect to the base member axis of rotation 48 .
- the drive motor 72 is connected to a drive motor gear drive assembly 112 which has internal gear assemblies (not shown) which are connected to a shaft housing 114 . Operation of drive motor 72 and the gear assembly within drive motor gear drive assembly 112 cause axial extension or retraction of an axial displacement shaft 116 with respect to the shaft housing 114 . The extension or retraction of axial displacement shaft 116 results in rotation of the drive rod 74 described in reference to FIG. 8 .
- a mounting pin 118 is connected to each of the sides of seat support frame 22 such that mounting pins 118 define the base member axis of rotation 48 .

Abstract
Description
- The present disclosure relates to furniture members having powered mechanisms providing for lift and zero gravity occupant positions.
- This section provides background information related to the present disclosure which is not necessarily prior art.
- Furniture members such as recliners, sofas, love seats, and ottomans commonly provide a structural frame supporting a body which allows the body to displace forwardly from an upright or seated operating position to a lift position which raises an occupant of the furniture member to an elevated position approximating a standing position. The lift mechanism is powered to assist the occupant who may not be able to stand effectively from the furniture member normal upright position. Known mechanisms allowing such lift travel do not, however, also permit a rearward tilt motion of the body to a zero gravity position while still maintaining wall clearance at all seatback member positions.
- This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
- According to several aspects, a furniture member powered mechanism providing both lift and zero gravity operating positions includes a first torque tube. First and second connecting links are fixed to the first torque tube. The first connecting link is rotatably connected to a first connecting arm and the second connecting link is rotatably connected to a second connecting arm. A gear housing has the first and second connecting arms rotatably connected to the gear housing. A positioning motor connected to the gear housing operates to slidably displace a slide member coupled to the gear housing. Slide member motion displaces the first and second connecting arms displacing and rotating the first torque tube. First and second connecting plates are rotatably connected to the slide member. A second torque tube is fixed at opposite ends to each of first and second arm rest portions of a base portion of the furniture member. The first and second connecting plates are also connected to the second torque tube such that displacement of the slide member causes rotation of the base member.
- According to other aspects, a furniture member powered mechanism providing both lift and zero gravity operating positions includes a first torque tube. First and second connecting links are fixed to the first torque tube. The first connecting link is rotatably connected to a first connecting arm and the second connecting link rotatably connected to a second connecting arm. A gear housing has the first and second connecting arms rotatably connected to the gear housing. A positioning motor is connected to the gear housing. Operation of the positioning motor slidably displaces a slide member slidably coupled to the gear housing. Sliding motion of the slide member acts to displace the first and second connecting arms, thereby displacing and rotating the first torque tube. Displacement of the first torque tube causes rotation of a base portion of the furniture member and rotation of the first torque tube, causing rotation of a seatback member coupled to the base portion. A drive motor is coupled to first and second pantograph linkage sets connected to a leg rest assembly. The first and second pantograph linkage sets and the leg rest assembly are displaced between a retracted and a fully extended position only by operation of the drive motor.
- According to further aspects, a furniture member powered mechanism providing both lift and zero gravity operating positions includes a gear housing having the first and second connecting arms rotatably connected to the gear housing. A positioning motor is connected to the gear housing. Operation of the positioning motor slidably displaces a slide member slidably coupled to the gear housing. Sliding motion of the slide member acts to displace and rotate a first torque tube. First and second connecting plates are rotatably connected to the slide member. A second torque tube is fixed at opposite ends to each of first and second arm rest portions of a base portion of the furniture member. The first and second connecting plates are also connected to the second torque tube such that displacement of the slide member causes rotation of the base member with respect to a base member axis of rotation. A drive motor is coupled to first and second pantograph linkage sets connected to a leg rest assembly. The first and second pantograph linkage sets and the leg rest assembly are displaced between a retracted and a fully extended position only by operation of the drive motor.
- Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
- The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

- Referring to
FIG. 1 , afurniture member 10 is represented as a reclining chair; however, thefurniture member 10 can also take the form of a recliner, a sofa, a loveseat, an ottoman, or similar furniture member design.Furniture member 10, in the embodiment of a reclining chair, includes abase member 12 which is supported by asupport frame 14 to a surface such as a floor. Aseatback member 16 is rotatably connected to thebase member 12 and is shown in a fully upright position. Thebase member 12 includes left and right side components including a firstarm rest portion 18 and a secondarm rest portion 20 positioned to the right or left of an occupant of thefurniture member 10. - The occupant weight is supported on a
seat support frame 22 which is rotatably and displaceably connected to theseatback member 16 such that rotation of the seatback member also causes displacement of theseat support frame 22. Aleg rest assembly 24 is positioned forward and below with respect to theseat support frame 22. Theleg rest assembly 24 is similar to common leg rest assemblies known in the art. Amechanism 26 is positioned between the first and secondarm rest portions base member 12, theseatback member 16, and theleg rest assembly 24. - Referring to
FIG. 2 , theleg rest assembly 24 is shown in a fully extended position and includes a first pantograph linkage set 28 which extends through afirst panel aperture 30 of a legrest abutment panel 32. The legrest abutment panel 32 is fixed to the first and secondarm rest portions FIG. 1 . A second pantograph linkage set 34 extends through asecond panel aperture 36 of the legrest abutment panel 32 and together with the first pantograph linkage set 28 is connected to and displaced by operation ofmechanism 26. - Referring to
FIG. 3 and again toFIG. 1 ,furniture member 10 is shown in the upright position, which includesseatback member 16 rotated to a fully forward or upright position. In addition, first and secondadjustable feet support frame 14 on both sides of thefurniture member 10. First and secondadjustable feet floor surface 42 and provide for leveling offurniture member 10 with respect tofloor surface 42. Each of the first and secondarm rest portions 18, 20 (only firstarm rest portion 18 is shown in this view) include a first arm rest face 44 which, in the furniture member upright position, is oriented substantially parallel with respect tofloor surface 42. A secondarm rest face 46, which intersects the firstarm rest face 44, is oriented at an angle α in the furniture member upright position. According to several aspects, angle α, at the furniture member upright position, defines an angle of approximately 20-30 degrees. The purpose for angle α will be evident by the further discussion with respect toFIG. 5 . - Referring to
FIG. 4 and again toFIG. 3 , thefurniture member 10 is shown after a rearward rotation with respect to a base member direction of rotation “A” about a base member axis ofrotation 48. Theseatback member 16 is retained at its fully forward or upright position at this time. Thefurniture member 10 is positioned in a fully rearward rotated position wherein the secondarm rest face 46 is oriented substantially parallel to thefloor surface 42. Theleg rest assembly 24 is shown in its fully retracted position; however, theleg rest assembly 24 can also be extended to its fully extended position with thefurniture member 10 at the fully rearward rotated position, which is shown and described in reference toFIG. 5 . - Referring to
FIG. 5 and again toFIG. 4 , with thefurniture member 10 fully rotated with respect to the base member direction of rotation “A”, as previously noted, the secondarm rest face 46 is oriented substantially parallel with respect tofloor surface 42. When theleg rest assembly 24 is subsequently extended to the fully extended position (shown), the legs of the occupant offurniture member 10 are fully supported byleg rest assembly 24. - Referring to
FIG. 6 and again toFIG. 5 , with thefurniture member 10 positioned in the fully rearward rotated position and theleg rest assembly 24 extended to the fully extended position, selective operation ofmechanism 26 will cause theseatback member 16 to rotate with respect tobase member 12 about a seatback member direction of rotation “B”, which is rearward with respect to an occupant offurniture member 10. Theseatback member 16 is linked to theseat support frame 22 using a first seatback member linkage set 50 and a second seatback member linkage set (not visible in this view). Due to the first seatback member linkage set 50, as theseatback member 16 rotates rearwardly, theseat support frame 22 is displaced forwardly. A zero gravity position forfurniture member 10 is defined when theseatback member 16 is positioned in a fully reclined position (shown) by rotation about the seatback member direction of rotation “B”, thebase member 12 is positioned in its fully rearward rotated position by rotation with respect to the base member direction of rotation “A”, and when theleg rest assembly 24 is in its fully extended position. The zero gravity position provides an elevation of the occupant's heart substantially level with or below the elevation of theleg rest assembly 24 at the fully extended position. - Referring to
FIG. 7 and again toFIGS. 1-6 , when theleg rest assembly 24 is positioned in its fully retracted position,furniture member 10 also provides for operation ofmechanism 26 to rotatably displace thebase member 12 in a forward arc of rotation “C” with respect to base member axis ofrotation 48. During rotation in the forward arc of rotation “C”, thebase member 12 rotates until the firstarm rest face 44 reaches an angle β defining a chair lift position angle between firstarm rest face 44 and thefloor surface 42. According to several aspects, angle β is approximately 30-40 degrees. The lift position offurniture member 10 provides for easy egress for the occupant to stand and move away fromfurniture member 10. As with the other operating conditions and positions forfurniture member 10,mechanism 26 provides for powered displacement ofbase member 12 to reach the lift position shown. - Referring to
FIG. 8 and again toFIG. 1 , multiple components ofmechanism 26, as well as of thebase member 12, will be described as follows. Thebase member 12 can be constructed using metal tubing which includes afirst frame tube 52 oriented substantially parallel to asecond frame tube 54. The first andsecond frame tubes arm rest portions rear cross tube 56 is fixedly connected between the first andsecond frame tubes support frame 14. Similarly, but oppositely positioned, afront cross tube 58 is fixedly connected between the first andsecond frame tubes support frame 14. The first and secondadjustable feet first frame tube 52. Similarly, first and secondadjustable feet 38′, 40′ are adjustably connected at opposite ends of an underside or floor facing surface of thesecond frame tube 54. - A
base side wall 60, made for example from plywood material, is fixed to thesecond frame tube 54. An oppositely facing base side wall is also provided with the first frame tube 52 (not visible in this view for clarity). A baserear wall 62 is fixedly connected between the base side walls and provides an opposite closure of thespace surrounding mechanism 26 together with legrest abutment panel 32. Each of the base side walls, such asbase side wall 60 shown is positioned within a space defined between an innerarm rest wall 64 of secondarm rest portion 20 and an outerarm rest wall 66 of secondarm rest portion 20. According to several aspects, inner and outerarm rest walls base side wall 60 within the space between inner and outerarm rest walls mechanism 26 even as thebase member 12 rotates to the full lift position shown and described with respect toFIG. 7 . - A second seatback member linkage set 68 is connected to
seatback member 16 on a right hand side and is a mirror image of first seatback member linkage set 50. Each of the first and second seatback member linkage sets 50, 68 are rotatably connected to afirst torque tube 70 which is oriented substantially parallel to therear cross tube 56 and thefront cross tube 58.First torque tube 70 is axially rotatable with respect to a longitudinal axis of thefirst torque tube 70 such that axial rotation offirst torque tube 70 causes displacement of the first and second seatback member linkage sets 50, 68 which results in rotation of theseatback member 16. As previously noted, each of the first and second seatback member linkage sets 50, 68 are also connected to theseat support frame 22 such that rotation of theseatback member 16 also displacesseat support frame 22 in a generally forward or rearward direction with respect to an occupant of thefurniture member 10. - For operation of the
leg rest assembly 24, aDC drive motor 72 is provided which is located at a forward end of thesupport frame 14. Operation of thedrive motor 72 causes axial rotation of adrive rod 74 with respect to a longitudinal axis of thedrive rod 74. Driverod 74 is oriented substantially parallel to thefirst torque tube 70. First andsecond support arms drive rod 74 and further connected to a support arm 76 positioned at a forward end ofbase member 12, and also oriented substantially parallel tofirst torque tube 70. The first and second pantograph linkage sets 28, 34 are both rotatably connected to each of thedrive rod 74 and thesupport rod 78, providing support for theleg rest assembly 24 in either the fully stowed or the fully extended positions. - To provide for powered operation of the
base member 12 to achieve the seatback member rotated positions, as well as thebase member 12 lift positions, apositioning motor 80 connected to agear housing 82 is located proximate to legrest drive motor 72. A gear assembly such as a worm gear (not shown) withingear housing 82 is rotated by operation of positioningmotor 80. Aslide member 84 is slidably disposed with respect to gearhousing 82 and connected to the gear assembly withingear housing 82. Rotation of the gear assembly withingear housing 82 with respect to a longitudinal axis of thegear housing 82 thereby causes either a forward or rearward displacement of theslide member 84 with respect to gearhousing 82. First and second connectingplates slide member 84 and are fixed with respect to asecond torque tube 88.Second torque tube 88 is also oriented substantially parallel with respect tofirst torque tube 70.Second torque tube 88 is fixed at opposite ends to each of the first and secondarm rest portions slide member 84 with respect to gearhousing 82 thereby causes rotation of thebase member 12 with respect to base member axis ofrotation 48 as described in reference toFIGS. 4-7 , as well as rotation of theseatback member 16, as will be further described herein. - In addition to the first and second connecting
plates slide member 84 is also connected to each of a first connectingarm 90 and a second connectingarm 92 which are positioned on and rotatably connected to opposite sides of theslide member 84. The first and second connectingarms link first torque tube 70. Linear displacement of theslide member 84 is thereby linked to thefirst torque tube 70, displacingfirst torque tube 70 and thereby providing motive force for rotation ofseatback member 16. - Referring to
FIG. 9 and again toFIG. 8 , as previously noted, the extension of the first and second pantograph linkage sets 28, 34 is accomplished by operation ofdrive motor 72. During displacement of the first and second pantograph linkage sets 28, 34, thesupport rod 78 is slidably displaced in a forward direction with respect to supportrod containment members 96 connected to opposite sides of theseat support frame 22. Rotation ofdrive rod 74 about its central longitudinal axis, as well as forward displacement of thesupport rod 78, thereby provides for full extension of the link members of first and second pantograph linkage sets 28, 34. Positioningmotor 80 is not operated during the extension or retraction of theleg rest assembly 24; therefore,slide member 84 displacement is not required for extension or retraction of theleg rest assembly 24. Axial rotation of thedrive rod 74 also causes a forward rotation of each of a first and asecond motion link support rod 78 such that rotation of the first and second motion links 98 a, 98 b produces the forward displacement ofsupport rod 78. - Referring to
FIG. 10 and again to FIGS. 1 and 8-9, to reach the seatback fully rearward rotated position shown, legrest drive motor 72 is not operated andpositioning motor 80 is electrically operated. Operation ofpositioning motor 80 causes a forward sliding displacement motion ofslide member 84. Because the first and second connectingplates slide member 84 and to thesecond torque tube 88, the forward sliding motion ofslide member 84 directly forwardly displaces thesecond torque tube 88 and, by its connection to each of the first and second connectingarms first torque tube 70 is also pulled forward. As theslide member 84 moves forward, the angle of orientation ofgear housing 82 is changed such that a rear facing end ofgear housing 82 rotates downwardly with respect to its nominal position shown inFIG. 8 . This downward displacement ofgear housing 82 causes a downward rotation at the rear end ofbase member 12. The forward displacement offirst torque tube 70 during this operation also results in theseatback member 16 being repositioned together with thebase member 12. When thefurniture member 10 reaches the seat member fully rearward rotated position (shown), a forwardlower corner 99 of each of the first and secondarm rest portions 18, 20 (only secondarm rest portion 20 is visible in this view) is both forwardly and upwardly displaced with respect to a corresponding location in the seat upright position shown inFIG. 1 . - Referring to
FIG. 11 and again to FIGS. 2 and 8-10, as previously noted, when thefurniture member 10 is positioned in the furniture member fully rearward rotated position, theleg rest assembly 24, including each of the first and second pantograph linkage sets 28, 34, can be extended to their fully extended position by operation ofdrive motor 72. This operation ofdrive motor 72 is independent of any operation of thepositioning motor 80 and therefore allows complete independent operation ofleg rest assembly 24. - Referring to
FIG. 12 and again toFIG. 8 ,slide member 84 can slide in either a forward or a rearward direction with respect to gearhousing 82 by operation of positioningmotor 80 in either of a forward or a rearward operational direction. In order to accommodate displacement of each of the first and second connectingarms slide member 84 using a slidemember connecting shaft 100. The axial sliding motion ofslide member 84 is therefore accommodated by the rotational connection between slidemember connecting shaft 100 and each of the first and second connectingarms gear housing 82 asslide member 84 axially displaces. - Referring to
FIG. 13 and again toFIG. 12 , to reposition thebase member 12 to the full lift position shown, positioningmotor 80 is operated which rotates a gear assembly (not shown) within agear drive assembly 102, thereby axially displacing theslide member 84 ongear housing 82 in a rearward and upward displacement direction “D”. Thepositioning motor 80 and thegear drive assembly 102 are together rotatably connected to thefront cross tube 58 by aclevis 104 extending from thegear drive assembly 102 which is rotatably connected to a U-bracket 106 using aclevis pin 108. TheU-bracket 106 is fixed to thefront cross tube 58 such that theclevis pin 108 defines a motor axis ofrotation 110. Rearward displacement of theslide member 84 and consequent rearward displacement of the first and second connectingarms seat support frame 22 and thebase member 12 in a forward or lift direction of rotation “C” with respect to the base member axis ofrotation 48. - The
drive motor 72 is connected to a drive motorgear drive assembly 112 which has internal gear assemblies (not shown) which are connected to ashaft housing 114. Operation ofdrive motor 72 and the gear assembly within drive motorgear drive assembly 112 cause axial extension or retraction of anaxial displacement shaft 116 with respect to theshaft housing 114. The extension or retraction ofaxial displacement shaft 116 results in rotation of thedrive rod 74 described in reference toFIG. 8 . In order to provide for rotation ofbase member 12, a mountingpin 118 is connected to each of the sides ofseat support frame 22 such that mountingpins 118 define the base member axis ofrotation 48. - Referring to
FIG. 14 and again toFIG. 6 , after thebase member 12 reaches the furniture member furthest rearward rotated position shown, further operation of positioningmotor 80 further slidably extends theslide member 84 in a forward direction “E” with respect to thegear housing 82. This displacement ofslide member 84 causes further forward displacement of thefirst torque tube 70 as well as forward displacement of theseat support frame 22. As thefirst torque tube 70 repositions forwardly, theseatback member 16 rotates in the seatback member direction of rotation “B” to the fully reclined position due to the linked connection between thefirst torque tube 70 and each of the first and second seatback member linkage sets 50, 68, as previously described. - Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.
- The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
- When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
- Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
- Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
- The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
