The present disclosure relates to collapsible canopies and, in particular, canopy frames having improved canopy frames and related frame components.
Description of the Related Art
Canopy shelters with collapsible frames are commonly used to provide portable shelter for outdoor activities such as camping, picnicking, parties, weddings, and more. Such collapsible canopy shelters typically comprise a canopy cover and a canopy frame configured to stand alone when in an expanded or deployed state and to collapse into a collapsed state for storage and transport.
While conventional canopy shelters are useful for a variety of purposes, such as providing portable shade and/or shelter from the elements and providing an aesthetically pleasing backdrop for special events, conventional canopy frames leave room for improvement with respect to structural integrity. Some conventional canopy frame designs are vulnerable to misalignment, excessive friction, and twisting, which make the canopy difficult to expand and collapse.
Canopy frames are generally constructed of cross members that pivot relative to one another during expansion and collapse of the frame. In certain configurations, particularly in a canopy frame including a center lift tube, perpendicular cross members (e.g., edge and interior members) come together at a T point. Some canopy frames utilize a bracket at the T point to position one cross member generally perpendicular to at least one additional cross member.
The systems, methods and devices described herein have innovative aspects, no single one of which is indispensable or solely responsible for their desirable attributes. Without limiting the scope of the claims, some of the advantageous features will now be summarized.

Throughout the drawings, reference numbers can be reused to indicate general correspondence between reference elements. The drawings are provided to illustrate example embodiments described herein and are not intended to limit the scope of the disclosure.
In some embodiments, the canopy frame 100 comprises a plurality of outer cross members 110 throughout the edge or perimeter of the canopy frame 100. The canopy frame 100 can further comprise a plurality of inner cross members 130 within the interior or perimeter of the canopy frame 100. In one embodiment, the inner cross members 130 are pivotally coupled to at least one outer cross member 110 and the center lift tube 140. As described herein, in some embodiments, the canopy frame 100 comprises more than one center lift tube (not illustrated). In some embodiments, the inner cross members may pivotally couple to multiple center lift tubes (not illustrated). In some embodiments, a plurality of inner cross members 130 may couple the outside cross members 110 to the center lift tube 140.
The illustrated bracket is an F-bracket 300 is configured to pivotally couple the inner cross member 130 to both the first outer cross member 110 and second outer cross member 110. In some arrangements, the F-bracket 300 comprises an inner portion 330, an intermediate portion 340, a first outer portion 310, and a second outer portion 320. The inner portion 330, first outer portion 310, and second outer portion 320 can be integrally connected to the intermediate portion 340 to form a generally “F” shape. The term F-bracket 300 is used as a convenience herein and is not intended to limit the shape of the bracket 300 unless otherwise indicated. In some configurations, the overall shape of the bracket 300 is an “F” shape; however, the bracket 300 can also have additional portions such that the overall shape is other than F-shaped. For example, the bracket could have an “S” shape. Different types of brackets can be used in a single canopy to position the canopy frame elements as desired. An example of such brackets and bracket arrangements is described in U.S. patent application Ser. No. 14/149,538, filed Jan. 7, 2014 and published as U.S. Publ. No. 2014/0190541, and entitled CANOPY SHELTER BRACKETS, the entirety of which is incorporated by reference herein.
In one embodiment the inner portion 330, first outer portion 310, and second outer portion 320 comprise substantially rectangular projections from the intermediate portion 340 configured to pivotally couple to a cross member 110, 130. In some embodiments, the inner portion 330, first outer portion 310, and/or second outer portion 320 comprise curved shapes and/or rounded corners. In some configurations, at least a portion of the intermediate portion 340 defines a thickness that is greater than the thickness of the inner portion 330, the first outer portion 310 and/or the second outer portion 320. In some configurations, the intermediate portion 340 is generally or substantially triangular in shape from a top view.
With continued reference to
In one embodiment, the bracket 300 is monolithic in construction. In other embodiments, however, the brackets may be constructed of multiple pieces joined together (not illustrated). In one embodiment, the brackets may be constructed of an assortment of materials, for example, rubber, plastic, thermoplastic, thermoset, acrylonitrile butadiene styrene, polycarbonate alloy, acetal, acrylic, nylon, polybutylene terephthalate, polyester liquid crystal polymer, polypropylene, polycarbonate, polyimide, polythelene, steel, stainless steel, aluminum, titanium, or another metal material, and/or any other connection method or system. In one embodiment, the brackets are formed in an injection molded process. However, the brackets can be formed used any other production method or technique, as desired or required. In one embodiment, the material may be reinforced with glass or carbon fibers. In some embodiments, the brackets may be formed through an extrusion process. In one embodiment, the brackets may be formed by bending a flat piece of material. In one embodiment, the brackets are coated with one or more coatings or layers to prevent or help protect against corrosion, as desired or required.
In the illustrated arrangement, at least one of the outer cross members 110 includes an end portion 400 having an abutting or abutment member, portion or extension 402 that extends toward or to the adjacent cross member of the frame. The abutment member or portion 402 can be advantageously sized, shaped and/or otherwise configured to fill a space created between the outer cross members 110 by the bracket 300 and, in particular, the first outer portion 310 of the bracket 300 that is positioned between the outer cross members 110.
Accordingly, in some embodiments, in response to forces (e.g., lateral forces) applied to the outer cross members 110 (e.g., by wind, intentional or inadvertent pushing, etc.), the abutment member or portion 402 can contact the opposite cross member 110 to provide additional amount of lateral rigidity to the cross members 110 and the canopy frame 110 as a whole. That is, instead of only the fastener 210 resisting lateral forces, the fastener 210 and contact between the abutment member or portion 402 and the opposite cross member 110 both resist lateral forces and increase the resistance to lateral movement of the cross members 110. In some configurations, the abutment member or portion 402 contacts the opposite cross member 110 (or a portion thereof, such as an endcap). However, in other configurations, the abutment member 402 fills a portion of the gap between the cross members 110 and contacts the opposite cross member 110 in response to some lateral movement therebetween. However, in some embodiments, the abutment member 402 extends at least one-half (e.g., one-half, two-thirds, three-quarters, seven-eighths, lengths between the foregoing, etc.) of the distance between the cross members 110 such that the abutment member or portion 402 contacts the opposite cross member 110 without requiring excessive lateral movement. In some configurations, the abutment member or portion 402 has a thickness in a direction toward the opposite cross member 110 that is at least one-half (e.g., one-half, two-thirds, three-quarters, seven-eighths, thicknesses between the foregoing, etc.) of a thickness of a portion of the bracket 300, such as the first outer portion 310 of the bracket 300, as desired or required.
With continued reference to
As described herein, in some configurations, the frame 100 comprises a plurality of leg assemblies or legs 60 that support the upper portion of the frame 100 and the cover 52. The legs 60 can be multi-portion, telescopic legs having multiple leg members that extend and retract relative to one another. In some configurations, the legs 60 include at least three telescoping leg members, including an upper or outer leg 62, an intermediate leg 64 and a lower or inner leg 66.
According to some embodiments, the automatic release 500 comprises a hollow body 502 (e.g., at least partially hollow) that is received within the lower end of the upper leg segment or portion 62 and allows the intermediate leg segment or portion 64 to pass, at least partially, through the body 502. In some arrangements, as illustrated in
The automatic release 500 can have one or more additional features, such as, for example, a retention arrangement 520, which assists in retaining the release body 502 within the upper leg 62. The illustrated retention arrangement 520 includes a protrusion 522 that contacts the inner surface of the upper leg 62 to increase the retention force of the release body 502. In some configurations, one or more slots 524 can be positioned near the protrusion 522 to permit inward flex of the body 502 to ease entry of the protrusion 522 into the upper leg 62. In the illustrated arrangement, the slots 524, which extend in a longitudinal direction, are placed on each side of the protrusion 522 and are substantially adjacent to the protrusion 522. The release body 502 can also include an elongate slot 526 that extends in a longitudinal direction of the body 502 and can accommodate portions of a lock mechanism (e.g., a push pin lock) for locking the folding eaves in a locked position. That is, in some embodiments, the slot 526 can accommodate a locking pin, for example, of a sliding bracket attached to a lower, outer cross member 110 and that slides on the upper leg 62 to collapse and deploy the canopy 50.
In the illustrated arrangement, the resilient portions 602 (and thus, in some embodiments, the corresponding gaps 603 or other features that help create the resilient portions) extend along one or more perimeter edges or sides of the cap 600. The portions 602 can be positioned on one, two, three, four or more sides of the cap 600. In the illustrated arrangement, the resilient portions 602 are coupled to the body of the cap 600 at corners and are spaced from the body along the sides of the cap 600. However, other suitable arrangements are also possible. For example, the resilient portions can take on any suitable form to apply a suitable force to the interior surface of a leg within which the cap 600 is inserted, preferably while allowing relatively easy insertion of the cap 600 into the leg for manufacturing purposes. Thus, while the illustrated resilient portions 602 are coupled to the body of the cap 600 at two locations (e.g., ends), in other arrangements the resilient portions 602 can be coupled at only one location or more than two locations.
As noted above, the use of such inwardly resilient caps 600 along an end of an interior leg or leg segment or portion can help ensure that adjacent legs are tightly or snugly maintained, especially when the legs are extended relative to one another. Thus, this can help enhance stability of an extended leg, reduce unwanted movement between adjacent leg segments and/or provide one or more additional benefits or advantages. At the same time, the cap's resiliency (e.g., its ability to retract at least partially inwardly) can permit the leg segments or portions to be selectively moved relative to one another (e.g., during extension or retraction of a leg).
