FIELD OF THE INVENTION

The present invention generally relates to frames and tables and, in particular, to frames and tables having structures for reducing vibration.

BACKGROUND

Foldable tables are more and more popular these days. A typical foldable table includes a table panel, a mounting frame and leg assemblies. The mounting frame is formed with holes to rotatably connect the leg assemblies so that the leg assemblies can be folded onto the table panel. However, in many existing foldable tables, there exist gaps at the connections between the mounting frame and leg assemblies. These gaps can cause vibration and consequently make the tables unstable when in use.

Given the current state of the art, there remains a need for frames and tables that address the abovementioned issues.

The information disclosed in this Background section is provided for an understanding of the general background of the invention and is not an acknowledgement or suggestion that this information forms part of the prior art already known to a person skilled in the art.

SUMMARY OF THE INVENTION

The present disclosure provides frames and tables having structures for reducing vibration.

In various exemplary embodiments, the present disclosure provides a table including a table panel, first and second mounting members, and first and second leg assemblies. The table panel includes first and second surfaces, first, second, third and fourth edges, and a plurality of retainers protruding away from the second surface. Of the plurality of retainers, at least one first retainer is disposed adjacent to the first edge and at least one second retainer is disposed adjacent to the second edge. The first mounting member is disposed adjacent to the third edge of the table panel and the second mounting member is disposed adjacent to the fourth edge of the table panel. Each of the first and second mounting members includes a first opening adjacent to the first edge of the table panel and a second opening adjacent to the second edge of the table panel. Each of the first and second leg assemblies includes a linking member disposed adjacent to the first or second edge of the table panel. The linking member includes a first end portion, a second end portion, and an engagement portion in between. The first end portion of the linking member is rotatably coupled with the first or second opening of the first mounting member and the second end portion of the linking member is rotatably coupled with the first or second opening of the second mounting member such that the first or second leg assembly is foldable with respect to the table panel. The engagement portion abuts against the at least one first or second retainer when the first or second leg assembly is unfolded. The abutting of the engagement portion against the at least one first or second retainer pushes the first end portion toward a far portion of the first or second opening of the first mounting member and the second end portion toward a far portion of the first or second opening of the second mounting member, thereby reducing a gap between the first or second end portion of the linking member and the far portion of the first or second opening of the first or second mounting member and thus reducing vibration when the table is in use.

In an exemplary embodiment, the abutting of the engagement portion against the at least one first or second retainer pushes the first end portion toward the far portion of the first or second opening of the first mounting member and the second end portion toward the far portion of the first or second opening of the second mounting member until the first end portion abuts against the far portion of the first or second opening of the first mounting member and the second end portion abuts against the far portion of the first or second opening of the second mounting member, thereby forming interference fit between the first or second end portion of the linking member and the far portion of the first or second opening of the first or second mounting member.

In some exemplary embodiments, the gap is reduced up to about 2 millimeters, up to about 3 millimeters, up to about 4 millimeters, or up to about 5 millimeters.

In some exemplary embodiments, each of the first and second openings has a substantially circular shape.

In an exemplary embodiment, the engagement portion of the linking member has a substantially circular cross-section.

In an exemplary embodiment, the engagement portion of the linking member has a substantially oval or oblong cross-section.

In some exemplary embodiments, each of the at least one first retainer and the at least one second retainer is formed with a recess toward the second surface of the table panel to receive, cross-section-wise, at least a portion of the engagement portion of the linking member.

In an exemplary embodiment, the recess has a bottom protruding away from the second surface of the table panel.

In some exemplary embodiments, cross-section-wise, the engagement portion of the linking member has a first dimension larger than a second dimension, and the first dimension abuts the recess when the first or second leg assembly is unfolded.

In some exemplary embodiments, each of the first and second leg assemblies is adjustable in length.

In some exemplary embodiments, the first or second leg assembly further includes first and second legs, first and second sliders, and first and second supporting members. Each of the first and second legs has an upper end portion fixedly coupled with the link member. The first slider is coupled with the first leg and slidable along a length direction of the first leg. The second slider is coupled with the second leg and slidable along a length direction of the second leg. The first supporting member has an end portion pivotally connected with the first slider and another end portion pivotally connected with the first mounting member. The second supporting member has an end portion pivotally connected with the second slider and another end portion pivotally connected with the second mounting member.

In an exemplary embodiment, the first or second leg assembly further includes a leg connecting member disposed between the first and second legs and connected with the first and second legs. Each of the first and second sliders includes a notch to couple with the leg connecting member when the first or second leg assembly is unfolded.

In some exemplary embodiments, the plurality of retainers further includes at least one third retainer and at least one fourth retainer. The at least one third retainer is configured to receive cross-section-wise at least a portion of the first or second leg of the first leg assembly when the first leg assembly is folded. The at least one fourth retainer is configured to receive cross-section-wise at least a portion of the first or second leg of the second leg assembly when the second leg assembly is folded.

In various exemplary embodiments, the present disclosure provides a supporting frame including first and second mounting members, and first and second leg assembles. Each of the first and second mounting members includes a first opening at or adjacent to a first end portion thereof and a second opening at or adjacent to a second end portion thereof. Each of the first and second openings has a polygonal shape with a plurality of edges. Each of the first and second leg assembles includes a linking member. The linking member includes a first end portion rotatably coupled with the first or second opening of the first mounting member and a second end portion rotatably coupled with the first or second opening of the second mounting member such that the first or second leg assembly is foldable with respect to the table panel. When the first or second leg assembly is unfolded, the first end portion of the linking member abuts at least two edges of the first or second opening of the first mounting member and the second end portion of the linking member abuts at least two edges of the first or second opening of the second mounting member, thereby forming interference fit to reduce vibration when the table is in use.

In an exemplary embodiment, each of the first and second openings has a diamond shape.

In some exemplary embodiments, each of the first and second openings has a first diagonal axis substantially parallel to a length direction of the first or second mounting member, and a second diagonal axis substantially perpendicular to the first diagonal axis.

DETAILED DESCRIPTION

Reference will now be made in detail to implementations of exemplary embodiments of the present disclosure as illustrated in the accompanying drawings. The same reference indicators will be used throughout the drawings and the following detailed description to refer to the same or like parts. Those of ordinary skill in the art will understand that the following detailed description is illustrative only and is not intended to be in any way limiting. Other embodiments of the present disclosure will readily suggest themselves to such skilled persons having benefit of this disclosure.

Many modifications and variations of the exemplary embodiments set forth in this disclosure can be made without departing from the spirit and scope of the exemplary embodiments, as will be apparent to those skilled in the art. The specific exemplary embodiments described herein are offered by way of example only, and the disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled.

Embodiments of the present disclosure are described in the context of frames and tables with structures that reduces vibration when the tables are in use. Generally, a table of the present disclosure includes a table panel, a mounting frame, and one or more leg assemblies which can be the same as or different from each other. The mounting frame is integrally formed or coupled with the table panel. Each leg assembly is rotatably coupled with the mounting frame and foldable to the table panel. The table of the present invention is configured with structures to reduce the gap at the connection between the mounting frame and leg assembly when the leg assembly is unfolded. In some exemplary embodiments, the gap is reduced such that interference fit is formed between the mounting frame and leg assembly, and/or between the table panel and leg assembly. The reduction in the gap and, in some cases, the interference fit, reduces vibration when the table is in use, and consequently enhances the stability and usability of the table.

The table panels can be of various shapes including but not limited to a square shape, a round shape or a rectangular shape. The panels can be made of various materials including but not limited to metals, plastics and woods. In some exemplary embodiments, the panels are made of plastics by injection molding, blow molding or any other suitable processes.

The mounting frame, one or more leg assemblies, other additional or optional structures, or any combination thereof, are collectively referred to herein as a supporting frame. The supporting frames of the present disclosure can be made of various materials including but not limited to metals (e.g., iron, steel, and aluminum) and plastics. In some exemplary embodiments, some components of a supporting frame (e.g., bars) are made of metals or the like while some other components (e.g., couplers, sliders) are made of plastics, rubbers or the like.

Referring now toFIGS.1A-4B, there is depicted exemplary table100in accordance with some embodiments of the present disclosure. As shown, table100includes a table panel such as table panel110, a mounting frame such as mounting frame140, and one or more leg assemblies. The one or more leg assemblies can be the same as or different from each other. By way of example, table100is shown with first and second leg assemblies such as leg assembly160.

Table panel110has first surface111and second surface112. The first and second surfaces of the table panel are generally the upper and lower surfaces of the table panel. Table panel110also includes a plurality of edges such as first edge113, second edge114, third edge115and four edge116. A plurality of retainers are integrally formed (e.g., during the blow molding process) or coupled (e.g., glued or fastener) with the table panel. In some exemplary embodiments, the plurality of retainers includes at least one first retainer disposed adjacent to the first edge of the table panel and at least one second retainer disposed adjacent to the second edge of the table panel. The first and second retainers can be the same as or different from each other. By way of example, two retainers120are shown adjacent to each of first edge113and second edge114of the table panel. Retainer120protrudes away from the second surface of the table panel (e.g., upwardly inFIGS.1A and3B).

Referring in particular toFIGS.3B and4B, there is depicted exemplary retainer120in accordance with some exemplary embodiments of the present disclosure. As shown, retainer120is integrally formed or coupled with second surface112of the table panel and protruded away from the second surface (e.g., at least a portion of the retainer is above the second surface as illustrated inFIG.3B). In some exemplary embodiments, retainer120is formed with a recess such as recess121concaved toward the second surface of the table panel. Recess121is formed with a bottom as bottom122protruding away from the second surface of the table panel (e.g., the bottom is above the second surface as illustrated inFIG.3B).

Referring in particular toFIGS.1A and1B, in some exemplary embodiments, the plurality of retainers includes at least one third retainer and at least one fourth retainer integrally formed or coupled with the table panel. The third and fourth retainers can be the same as or different from each other. The third and fourth retainers can also be aligned with each other along the length direction of the table panel or staggered with respect to each other, e.g., not aligned along the length or width direction of the table panel. By way of example, two retainers125are shown, one adjacent to third edge115and one adjacent to four edge116of the table panel.

In some exemplary embodiments, each of the third and fourth retainers includes a base integrally formed or coupled with the table panel and two lever arms extended from the table collectively forming a receiving portion that receives a leg or a portion of a leg (cross-section-wise). Examples of such retainers and/or other relevant features are disclosed in U.S. patent application Ser. No. 17/069,458, the disclosure of the application is incorporated herein for all purposes by reference in its entirety.

Mounting frame140is integrally formed (e.g., during the blow molding process) or coupled (e.g., glued or fastener) with the table panel. In some exemplary embodiments, mounting frame140includes a first mounting member such as first mounting member142and a second mounting member such as second mounting member144. The first mounting member is coupled or integrally formed with the table panel adjacent to the third edge of the table panel and the second mounting member coupled or integrally formed with the table panel adjacent to the third edge of the table panel. The first and second mounting members can be the same or different from each other. Each of the first and second mounting members includes a first opening adjacent to the first edge of the table panel and a second opening adjacent to the second edge of the table panel. The first and second openings can be the same as or different from each other. By way of example, the first and second mounting members are shown to be substantially the same with opening146adjacent to each of first edge113and second edge114of the table panel. In an exemplary embodiment, opening146has a substantially circular shape.

The first openings of the first and second mounting members are aligned with the at least one first retainer, e.g., openings146adjacent to first edge113are aligned with retains120adjacent to first edge113. Similarly, the second openings of the first and second mounting members are aligned with the at least one second retainer, e.g., openings146adjacent to second edge114are aligned with retains120adjacent to second edge114. Each of the first and second openings of the first and second mounting members has a near portion that is relatively closer to the second surface of the table panel and a far portion that is relatively farther away from the second surface of the table panel. For instance, as illustrated inFIG.2C, opening146has near portion146arelatively closer to second surface112of the table panel and far portion146brelatively farther away from the second surface of the table panel compared to near portion146a.

Each of the first and second leg assemblies includes a linking member for rotatably connecting the leg assembly with the mounting frame such that the leg assembly can be folded onto the table panel. For instance, leg assembly160includes linking member162. The first leg assembly has linking member162disposed adjacent to first edge113of the table panel and the second leg assembly has linking member162disposed adjacent to second edge114of the table panel.

Linking member162includes a first end portion such as first end portion163and a second end portion such as second end portion164. First end portion163is rotatably coupled with opening146of the first mounting member. Second end portion164is rotatably coupled with opening146of the second mounting member. As such, leg assembly160is rotatable respect to the table panel between a use position as illustrated inFIG.1A(the table is in an unfolded state) and a storage position as illustrated inFIG.1B(the table is in a folded state).

In some exemplary embodiments, linking member162further includes an engagement portion such as engagement portion165between the first and second end portions. The engagement portion can have any suitable shape and length. In an exemplary embodiment, the engagement portion of the linking member has a substantially circular cross-section as illustrated inFIG.2E.

The engagement portion is configured to couple with retainer120. For instance, in some exemplary embodiments, the engagement portion abuts against retainer120when the leg assembly is unfolded, e.g., in the use position as illustrated inFIG.1A. In some exemplary embodiments, recess121of retainer120receives, cross-section-wise, at least a portion of the engagement portion of the linking member. In some exemplary embodiments, a gasket, a padding or the like is provided at the recess or at the engagement portion of the linking member.

The abutting of the engagement portion against the retainer pushes the first end portion toward far portion146bof opening146of the first mounting member and the second end portion toward far portion146bof opening146of the second mounting member. Consequently, it reduces the gap between the first end portion and far portion146bof opening146of the first mounting member and reduces the gap between the second end portion and far portion146bof opening146of the second mounting member.

In some exemplary embodiments, the abutting of the engagement portion (e.g., engagement portion165) against the at least one first or second retainer (e.g., retainer120) reduces the gap between the first or second end portion of the linking member (e.g., linking member162) and the far portion of the opening of the first or second mounting member up to 2 millimeters, up to 3 millimeters, up to 4 millimeters, or up to 5 millimeters. In some exemplary embodiments, the abutting of the engagement portion against the retainer pushes the first end portion toward far portion146bof opening146of the first mounting member and the second end portion toward far portion146bof opening146of the second mounting member until the first end portion abuts against far portion146bof opening146of the first mounting member and the second end portion abuts against far portion146bof opening146of the second mounting member. As such, when the leg assembly is unfolded, the linking member forms interference or tighter fit with all of the first mounting member, the second mounting member and the table panel. This significantly reduces vibration when the table is in use.

In some exemplary embodiments, leg assembly160includes one or more legs each having an upper end portion fixedly coupled with the link member. The one or more legs can be the same as or different from each other. By way of example, leg assembly160is illustrated with two legs172each having an upper end portion fixedly coupled with link member162. In an exemplary embodiment, leg assembly160also includes a leg connecting member such as leg linking member174disposed between the first and second legs and connected with the first and second legs. In some exemplary embodiments where the table panel has retainer125, at least one leg of leg assembly160is coupled with retainer125(e.g., cross-section-wise, at least a portion of the leg is received in the retainer) when folded to the table panel. Retainer125retains the leg assembly and prevents it from accidental unfolding.

In some exemplary embodiments, leg assembly160is adjustable in length. For instance, in an exemplary embodiment, each of the first and second legs of leg assembly160includes first bar172aand second bar172btelescopically coupled with each other and a locking/unlocking mechanism to control relative movement of the first and second bars. Examples of adjustable leg assemblies and/or other relevant features are disclosed in U.S. patent applications Ser. Nos. 15/400,861, 15/931,925, 16/838,939, 16/838,944, 17/000,661, 17/003,047, 17/038,369 and 17/069,458, the disclosure of each application is incorporated herein for all purposes by reference in its entirety. As such, when unfolded, one can change the height of the table panel by adjusting collectively the lengths of the first and second legs of the leg assemblies. In some exemplary embodiments, the height of the table panel is adjustable for at least two, three, four or more positions.

In some exemplary embodiments, corresponding to one or each of the first and second legs, leg assembly160includes a slider such as slider180and a supporting member such as supporting member190to couple the leg with the first or second mounting member. Examples of sliders are disclosed in U.S. patent applications Ser. Nos. 16/838,939, 16/838,944 and 16/838,947, the disclosure of each application is incorporated herein for all purposes by reference in its entirety.

Slider180can be disposed at a leg or a mounting member. By way of example, slider180is shown at the leg. In an exemplary embodiment, slider180includes a body such as body181configured to sleeve on the leg such that slider180is movable along the length direction of the leg. Supporting member190has an end portion pivotally connected with the slider and another end portion pivotally connected with the first or second mounting member. As such, the combination of the slider and supporting member assists in guiding the folding and unfolding of the leg assembly with respect to the table panel.

Slider180also includes a button such as button182. Button182is operably coupled with the body to selectively restrict body181of the slider from moving along the length direction of the leg. For instance, when the table is in use, the button operates to restrict body181of the slider from moving along the length direction of the leg. As such, the combination of the slider and supporting member assists in supporting the table panel and prevents accidental folding of the leg assembly.

In some exemplary embodiments, slider180includes additional, optional or alternative features. For instance, in some exemplary embodiments, a notch such as notch183is formed at the body of the slider and configured to couple with the leg linking member when the leg assembly is unfolded. The coupling of the notch with the leg linking member prevents the leg from unfolding beyond its use position.

Referring now toFIGS.5A-7G, there is depicted exemplary table200in accordance with some embodiments of the present disclosure. Similar to table100, table200includes table panel110, first mounting member142and second mounting member144. First mounting member142is coupled or integrally formed with the table panel adjacent to the third edge of the table panel and second mounting member144is coupled or integrally formed with the table panel adjacent to the third edge of the table panel. Table200further includes one or more leg assemblies, which can be the same as or different from each other. By way of example, table200is shown with two leg assemblies260.

In some exemplary embodiments, leg assembly260is substantially the same as leg assembly160except the linking member. For instance, leg assembly260includes a linking member such as linking member262for rotatably connecting the leg assembly with the mounting members such that the leg assembly can be folded onto the table panel. Leg assembly260also includes first and second legs such as leg172each having an upper end portion fixedly coupled with link member262. Leg assembly260can be adjustable or non-adjustable in length. In an exemplary embodiment, leg assembly260additionally or optionally includes a leg connecting member such as leg linking member174disposed between the first and second legs and connected with the first and second legs. In some exemplary embodiments, corresponding to one or each of the first and second legs, leg assembly260includes slider180and supporting member190to couple the leg assembly with the first or second mounting member.

Referring in particular toFIGS.5A-5B,6A-6B and7A-7B, linking member262includes a first end portion such as first end portion263, a second end portion such as second end portion264, and an engagement portion such as engagement portion265between the first and second end portions. First end portion263is rotatably coupled with opening146of the first mounting member and second end portion264is rotatably coupled with opening146of the second mounting member such that leg assembly260is rotatable respect to the table panel between a use position as illustrated inFIG.7A(the table is in an unfolded state) and a storage position as illustrated inFIG.5A(the table is in a folded state).

Engagement portion265is coupled with retainer120. Unlike engagement portion165of linking member160, engagement portion265does not have a circular cross-section. Instead, cross-section-wise, it has a first dimension generally larger than a second dimension. For instance, referring in particular toFIGS.5F,6F and7G, cross-section-wise, engagement portion265of linking member260has first dimension266larger than second dimension267. Engagement portion265can be made, for instance, by pressing or flattening a circular tube. In an exemplary embodiment, the engagement portion of the linking member has a substantially oval or oblong cross-section, and the first and second dimensions align with the longer and shorter axes of the oval or oblong cross-section. When the leg assembly is unfolded, the first dimension abuts against the retainer and thus pushes the first end portion toward far portion146bof opening146of the first mounting member and the second end portion toward far portion146bof opening146of the second mounting member. Accordingly, it reduces the gap between the first end portion and far portion146bof opening146of the first mounting member and the gap between the second end portion and far portion146bof opening146of the second mounting member.

In some exemplary embodiments, the abutting of the engagement portion (e.g., engagement portion265) against the at least one first or second retainer (e.g., retainer120) reduces the gap between the first or second end portion of the linking member (e.g., linking member262) and the far portion of the opening of the first or second mounting member up to 2 millimeters, up to 3 millimeters, up to 4 millimeters, or up to 5 millimeters. In some exemplary embodiments, the abutting of the engagement portion against the retainer pushes the first end portion toward far portion146bof opening146of the first mounting member and the second end portion toward far portion146bof opening146of the second mounting member until the first end portion abuts against far portion146bof opening146of the first mounting member and the second end portion abuts against far portion146bof opening146of the second mounting member. As such, when the leg assembly is unfolded, the linking member forms interference or tighter fit with all of the first mounting member, the second mounting member and the table panel. This significantly reduces vibration when the table is in use.

Referring now toFIGS.8A-8F, there is depicted exemplary table300in accordance with some embodiments of the present disclosure. Similar to table100, table300includes a table panel such as table panel110, a first mounting member such as first mounting member342and a second mounting member such as second mounting member344. First mounting member342is coupled or integrally formed with the table panel adjacent to the third edge of the table panel and second mounting member344is coupled or integrally formed with the table panel adjacent to the third edge of the table panel. Table300further includes one or more leg assemblies, which can be the same as or different from each other. By way of example, table300is shown with two leg assemblies360.

Like the first and second mounting members of table100, each of the first and second mounting members of table300includes a first opening adjacent to the first edge of the table panel and a second opening adjacent to the second edge of the table panel. The first and second openings can be the same as or different from each other. By way of example, the first and second mounting members of table300are shown to be substantially the same with opening346adjacent to each of first edge113and second edge114of the table panel. In some exemplary embodiments, opening346has a polygonal shape with a plurality of edges. For instance, in an exemplary embodiment, opening346has a diamond shape with four edges. In some exemplary embodiments, opening346has a first diagonal axis substantially parallel to a length direction of the first or second mounting member, and a second diagonal axis substantially perpendicular to the first diagonal axis as illustrated inFIGS.8E and8F.

Leg assembly360includes a linking member such as linking member362having first and second end portions such as end portion364. The first end portion is rotatably coupled with opening346of the first mounting member and the second end portion is rotatably coupled with opening346of the second mounting member such that the first or second leg assembly is foldable with respect to the table panel. In an exemplary embodiment, linking member362is substantially the same as linking member162(e.g., having a substantially circular cross-section) or linking member262(e.g., having a flattened engagement portion). In another exemplary embodiment, linking member362having a polygonal cross-section (e.g., square) or the like.

When the leg assembly is unfolded, the first end portion of the linking member abuts at least two edges of opening346of the first mounting member and the second end portion of the linking member abuts at least two edges of opening346of the second mounting member. The abutting of the linking member against at least two edges of opening346forms interference fit between the linking member and the first and second mounting members, thereby reducing vibration when the table is in use. In some exemplary embodiments, as illustrated inFIGS.8A and8C, when the leg assembly is folded onto the table panel, the first end portion of the linking member also abuts at least two edges of opening346of the first mounting member and the second end portion of the linking member abuts at least two edges of opening346of the second mounting member. As such, it prevents accidental unfolding of the leg assemblies.

Referring now toFIGS.9A-9C, there is depicted exemplary table400in accordance with some embodiments of the present disclosure. Similar to table100, table400includes a table panel such as table panel110, a first mounting member such as first mounting member142and a second mounting member such as second mounting member144. Table400further includes one or more leg assemblies, which can be the same as or different from each other. By way of example, table400is shown with two leg assemblies460.

Leg assembly460includes a linking member such as linking member462with first and second end portions such as end portion464. The first end portion is rotatably coupled with opening146of the first mounting member and the second end portion is rotatably coupled with opening146of the second mounting member such that the leg assembly is foldable with respect to the table panel.

In some exemplary embodiments, each of the first and second end portions of linking member462is tapered (e.g., the nominal diameter of the cross-section reduces toward the end). The tapered first end portion facilitates easy insertion into the opening of the first mounting member and, once inserted, forms interference fit with the opening of the first mounting member. Similarly, the tapered second end portion facilitates easy insertion into the opening of the second mounting member and, once inserted, forms interference fit with the opening of the second mounting member. As such, it reduces vibration when the table is in use. For instance, in an exemplary embodiment, opening146has a substantially circular shape, and each of the first and second end portions of linking member462has a substantially conic or truncated conic shape. While the smaller end tip allows easy insertion into the opening, the gradually increased end portion forms relatively tighter fit with the opening, thereby reducing vibration when the table is in use. The relatively tighter fit also prevents accidental unfolding of the leg assemblies.

The terminology used herein is for the purpose of describing particular implementations only and is not intended to be limiting of the claims. As used in the description of the implementations and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be understood that the terms “top” or “bottom”, “lower” or “upper”, and etc. are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the figures. It will be understood that, although the terms “first,” “second,” etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first bar could be termed a second bar, and, similarly, a second bar could be termed a first bar, without changing the meaning of the description, so long as all occurrences of the “first bar” are renamed consistently and all occurrences of the “second bar” are renamed consistently.
