Detailed Description
Embodiments of the present disclosure are described herein. However, it is to be understood that the disclosed embodiments are merely exemplary, and that other embodiments may take various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention. As one of ordinary skill in the art will appreciate, various features illustrated and described with reference to any one of the figures may be combined with features shown in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combination of features shown provides a representative embodiment of a typical application. However, various combinations and modifications of the features consistent with the teachings of the present disclosure may be desired for particular applications or implementations.
Certain terminology may be used in the following description for the purpose of reference, and is therefore not intended to be limiting. For example, terms such as "above" and "below" refer to directional references in the drawings. Terms such as "front," "rear," "left," "right," "rear," and "side" describe the orientation and/or position of portions of the component or element within a consistent but arbitrary frame of reference as made clear by reference to the text and associated drawings describing the component or element in question. Moreover, terms such as "first," "second," "third," and the like may be used to describe individual components. Such terms may include the words specifically mentioned above, derivatives thereof, and words of similar import.
Some embodiments of a rear access panel/rear access (RAP/RSA) door include an upper latch assembly and a lower latch assembly connected by a cable or wire. In some cases, due to dimensional variations and other factors, the release of the upper and lower latches is not synchronized, resulting in poor unlocking sound quality and perceived door quality issues. The clip assembly according to the embodiments discussed herein enables the cable length between the upper and lower latches to be adjusted to improve the synchronization of the upper and lower latch releases. Although the embodiments of the clamp assembly discussed herein are discussed in the context of a RAP/RSA door latch assembly, the clamp assembly may be used with any closure system that includes multiple latches, including for example, but not limited to, sliding door latch assemblies and lifting door latch assemblies.

It should be emphasized that many variations and modifications may be made to the embodiments described herein, the elements of which are to be understood as being other acceptable examples. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims. Further, any of the steps described herein may be performed simultaneously or in a different order than the steps ordered herein. Further, it should be apparent that the features and attributes of the specific embodiments disclosed herein may be combined in different ways to form additional embodiments, all of which fall within the scope of the present disclosure.
As used herein, conditional language, such as "capable," "may," "for example," and the like, is generally intended to mean that certain embodiments include certain features, elements, and/or states, while other embodiments do not include certain features, elements, and/or states, unless specifically stated otherwise or otherwise understood in the context of use. Thus, such conditional language is not generally intended to imply that features, elements, and/or states are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements, and/or states are included in any particular embodiment or are to be performed.
Further, the following terminology may be used herein. The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an item includes reference to one or more items. The terms "a" or "an" refer to one, two, or more, and generally apply to the selection of some or all of the numbers. The term "plurality" refers to two or more items. The terms "about" or "approximately" mean that the quantity, dimensions, size, formulation, parameters, shape, and other characteristics need not be exact, but may be approximate and/or larger or smaller as desired to reflect acceptable tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art. The term "substantially" means that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations (including, for example, tolerances, measurement error, measurement accuracy limitations, and other factors known to those skilled in the art) may not preclude the occurrence of quantities of the effect that the feature is intended to provide.
Numerical data may be represented or presented herein in a range format. It is to be understood that such range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As illustrated, a numerical range of "about 1 to 5" should be interpreted to include not only the explicitly recited values of about 1 to 5, but also to include individual values and sub-ranges within the indicated range. Accordingly, included within this numerical range are individual values, such as 2, 3, and 4, and sub-ranges, such as "about 1 to about 3", "about 2 to about 4", and "about 3 to about 5", "1 to 3", "2 to 4", "3 to 5", and the like. This same principle applies to ranges reciting only one numerical value (e.g., "greater than about 1"), and should apply regardless of the breadth or character of the range. For convenience, multiple items may be presented in a common list. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary. Furthermore, where the terms "and" or "are used in conjunction with a list of items, they are to be interpreted broadly, as any one or two of the listed items can be used alone or in combination with the other listed items. The term "alternative" refers to the selection of one of two or more alternatives, and is not intended to limit the selection to only those listed alternatives or only one listed alternative at a time, unless the context clearly indicates otherwise.
While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms encompassed by the claims. The words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure. As previously mentioned, features of the various embodiments may be combined to form additional exemplary aspects of the present disclosure that may not be explicitly described or illustrated. While various embodiments may be described as providing advantages or being preferred over other embodiments or over prior art implementations with respect to one or more desired characteristics, those of ordinary skill in the art will recognize that one or more features or characteristics may be compromised to achieve desired overall system attributes, which depend on the specific application and implementation. These attributes may include, but are not limited to, cost, strength, durability, life cycle cost, marketability, appearance, packaging, size, maintainability, weight, manufacturability, ease of assembly, and the like. Thus, embodiments described as inferior to other embodiments or prior art embodiments with respect to one or more characteristics are not within the scope of the present disclosure and may be desirable for particular applications.
