In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration embodiments that may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope.

Alternate embodiments may be devised without departing from the spirit or the scope of the invention. Additionally, well-known elements of exemplary embodiments of the systems and methods will not be described in detail or will be omitted so as not to obscure the relevant details of the systems and methods.
Before the systems and methods are disclosed and described, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. The terms “comprises,” “comprising,” or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element. The terms “including” and/or “having,” as used herein, are defined as comprising (i.e., open language). The terms “a” or “an”, as used herein, are defined as one or more than one. The term “plurality,” as used herein, is defined as two or more than two. The term “another,” as used herein, is defined as at least a second or more. The description may use the terms “embodiment” or “embodiments,” which may each refer to one or more of the same or different embodiments.
The terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, “connected” may be used to indicate that two or more elements are in direct physical or electrical contact with each other. “Coupled” may mean that two or more elements are in direct physical or electrical contact (e.g., directly coupled). However, “coupled” may also mean that two or more elements are not in direct contact with each other, but yet still cooperate or interact with each other (e.g., indirectly coupled).
For the purposes of the description, a phrase in the form “A/B” or in the form “A and/or B” or in the form “at least one of A and B” means (A), (B), or (A and B), where A and B are variables indicating a particular object or attribute. When used, this phrase is intended to and is hereby defined as a choice of A or B or both A and B, which is similar to the phrase “and/or”. Where more than two variables are present in such a phrase, this phrase is hereby defined as including only one of the variables, any one of the variables, any combination of any of the variables, and all of the variables, for example, a phrase in the form “at least one of A, B, and C” means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C).
Relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The description may use perspective-based descriptions such as up/down, back/front, and top/bottom. Such descriptions are merely used to facilitate the discussion and are not intended to restrict the application of disclosed embodiments. Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding embodiments; however, the order of description should not be construed to imply that these operations are order dependent.
As used herein, the term “about” or “approximately” applies to all numeric values, whether or not explicitly indicated. These terms generally refer to a range of numbers that one of skill in the art would consider equivalent to the recited values (i.e., having the same function or result). In many instances these terms may include numbers that are rounded to the nearest significant figure.
Herein various embodiments of the systems and methods are described. In many of the different embodiments, features are similar. Therefore, to avoid redundancy, repetitive description of these similar features may not be made in some circumstances. It shall be understood, however, that description of a first-appearing feature applies to the later described similar feature and each respective description, therefore, is to be incorporated therein without such repetition.
Described now are exemplary embodiments. Referring now to the figures of the drawings in detail and first, particularly to
The canopy assembly 100 includes a fastener 1 (e.g., a screw), a canopy frame 2 (only a portion of the canopy is shown), two canopy ratchet parts 3, 11, a canopy sling rail housing 4, a thumb screw 5, a frame lock 6, two non-elastic washers 8, 13 (e.g., metal washers), two elastic washers 9, 12, and a locking nut 10. A portion of a sling-rail chair frame 7 is shown for illustrative purposes. As used herein, non-elastic means that the material is substantially incompressible and elastic means that the material is compressible. Therefore, the non-elastic washers 8, 13 can be, e.g., of metal, such as stainless steel, aluminum, and nickel, and the elastic washers can be, e.g., of rubber or plastic. The portion of the canopy frame 2 that is shown in
In one exemplary embodiment, the screw 1 has a size of ¼″-20×3½″ (i.e., the screw has a gauge of ¼″ inch, 20 threads per inch, and a length of 3½″ inches). In one exemplary embodiment, locking nut 10 is a stainless steel nut with a nylon lock nut. In one exemplary embodiment, the flexible washers 9, 12 are rubber washers but they can also be of neoprene. In one exemplary embodiment, metal washers 8, 13 are stainless steel and neoprene washer assemblies.
To assemble the canopy assembly 100, the screw 1 is passed through (in order): the canopy frame 2; a first canopy ratchet part 3; a second canopy ratchet part 11; the canopy sling rail housing 4; the frame lock 6; a first metal washer 8; a first rubber washer 9; a second rubber washer 12; and a second metal washer 13. The locking nut 10 is rotated along the threads of the screw to tighten elements 2, 3, 4, 6, 8, 9, 11, 12, and 13 together.
In one exemplary embodiment, the thumb screw 5 works in conjunction with the frame lock 6 to lock sling rail 7 into place. Sling rail 7 can then be inserted into an opening of a chair back portion 510, 610. In another embodiment, the thumb screw 5 works in conjunction with the frame lock 6 to lock the canopy sling rail housing 4 in place after it has been inserted over a chair back portion 510, 610. The canopy sling rail housing 4 has an opening 815, shown best in
The rear of the canopy sling rail housing 4 has two vertical portions 1605, 1610 and an angled connecting portion 1615. In an exemplary embodiment, a horizontal displacement D2 from the first vertical portion 1605 to the second vertical portion 1610 (i.e., the face for the thumb screw 5 and behind which is the frame lock 6) is 9.5 mm. The vertical portion 1605 and the angled connecting portion 1615 are positioned relative to each other at an angle A, which, in an exemplary embodiment, is 130 degrees.
