Abstract
Aspects of the present disclosure provide retractable canopies, kits of parts for assembling retractable canopies, and methods for assembling and operating retractable canopies. The retractable canopies provide tracks extending in a longitudinal direction and transversely spaced apart. A support extends in a transverse direction between the tracks and is moveably coupled to the tracks via mounts to the tracks. The mounts include engagement members, such as wheels, to engage with the tracks. The engagement members may be biased transversely away from the support (e.g. toward the track), thereby permitting the engagement members to adjust their transverse positions relative to the support as the support moves along the track.

DESCRIPTION
(11) Throughout the following description specific details are set forth in order to provide a more thorough understanding to persons skilled in the art. However, well known elements may not have been shown or described in detail to avoid unnecessarily obscuring the disclosure. Accordingly, the description and drawings are to be regarded in an illustrative, rather than a restrictive, sense.
(12) Aspects of the present disclosure provide retractable canopies, kits of parts for assembling retractable canopies, and methods for assembling and operating retractable canopies. The retractable canopies provide tracks extending in a longitudinal direction and transversely spaced apart. A support extends in a transverse direction between the tracks and is moveably coupled to the tracks via mounts to the tracks. The mounts include engagement members, such as wheels, to engage with the tracks. The engagement members may be biased transversely away from the support (e.g. toward the track), thereby permitting the engagement members to adjust their transverse positions relative to the support as the support moves along the track.
(13)
(14)
(15) Supports 22 may be of any suitable dimension. For example, in some embodiments, supports 22 may extend approximately 2 to 6 meters in transverse direction 8. For instance, supports 22 may extend approximately 391.8 cm (154.25 inches) in transverse direction 8. Supports 22 may be telescoping, resilient, or otherwise capable of changing their dimension in transverse direction 8. Supports 22 may comprise tubes having a radial diameter of 1.5875 cm (0.625 inches) and a wall thickness of 0.16 cm (0.063 inches).
(16) Panels 24 are supported by and extend between supports 22. Canopy 20 may comprise one or more panels 24. In some embodiments, canopy 20 comprises a single panel 24 supported by each of a plurality of supports 22. For example, panels 24 may be threaded through channels in some or all supports 22. In some embodiments, canopy 20 comprises a plurality of panels 24, each panel 24 supported by a subset of the plurality of supports 22. For example, each panel 24 may be supported by a pair of supports 22 which are adjacent to one another in longitudinal direction 6. For instance, as shown in
(17) Supports 22 supporting panels 24 may move relative to other supports 22. Panels 24 may be designed to accommodate relative movement of supports 22 while panels 24 are being supported by supports 22. For example, panels 24 may comprise a flexible material, as depicted in
(18) Supports 22 are coupled to tracks 26 via mounts 30. Tracks 26 are spaced apart from one another in transverse direction 8 and extend in longitudinal direction 6. Supports 22 extend in transverse direction 8 between tracks 26. One or more of supports 22 are movable relative to tracks 26 in longitudinal direction 6. Tracks 26 may comprise any suitable shape and dimension for the mounting of supports 22 via a mount. For example, tracks 26 may comprise rails, gaskets, sliding tracks, channels, bars, tubes, and/or other geometries and may be straight, curved, and/or otherwise shaped, so long as supports 22 are able to be coupled to and move along the length of tracks 26 in longitudinal direction 6. Tracks 26 may be made of any suitable material, such as plastics, metals, and/or other materials. In some embodiments, tracks 26 comprise aluminum channels.
(19) Tracks 26 may be of any suitable dimension. For example, tracks 26 may be approximately 1 to 5 meters long in longitudinal direction 6. For instance, tracks 26 may be approximately 2.5 m (approximately 8 feet) long in longitudinal direction 6. Tracks 26 may be shorter or longer, as appropriate, and/or multiple tracks 26 may be arranged in series to provide for a greater dimension in longitudinal direction 6.
(20)
(21) In some embodiments, engagement member 32 may be biased (e.g. forced) away from support 22 and toward track 26. Such biasing may assist, for example, in providing smoother motion of supports 22 as they move relative to tracks 26 in longitudinal direction 6. In some embodiments, one or more supports 22 each have a plurality of mounts 30 with biased engagement members 32 (e.g. mounts 30 may be coupled to supports 22 at opposing transverse ends 61, shown in
(22)
(23) In the example embodiment of
(24)
(25) In some embodiments, at least a portion of axle 41 is movable in transverse direction 8 relative to transverse end 61 of support 22. For example, axle 41 may be extendable (e.g. telescopically), thereby permitting the movement of a first portion 46 of axle 41 (to which wheel 32A may be coupled) relative to a second portion 47 of axle 41 (which may be coupled to cap 50). As another example, axle 41 may be of fixed dimension in transverse direction 8, and axle 41 as a whole may be moveable in transverse direction 8 relative to transverse end 61 of support 22. This movement of at least a portion of axle 41 may be biased in transverse direction 8 away from transverse end 61 of support 22 (e.g. towards track 26).
(26) In the illustrated embodiment, axle 41 comprises a first portion 46 and a second portion 47. First portion 46 slides over second portion 47 and second portion 47 is received in a transversely oriented bore of first portion 46, thereby permitting axle 41 to telescope by relative transverse movement between first and second portions 46, 47. First portion 46 has a first surface 42 on which wheel 32A (or other engagement member 32) may be coupled. Wheel 32A may be retained on first surface 42 by any suitable mechanism, such as C-clip 37. A bearing 38 may be coupled to second surface 44 of first portion 46 and may bear against wheel 32A to provide smooth rotational motion.
(27) The telescoping motion of axle 41 may be biased (e.g. forced) away from transverse end 61 of support 22, e.g. as described above. In some embodiments, a spring 52 is retained by axle 41 and biases first portion 46 away from transverse end 61. For example, spring 52 may wrap around second portion 47 and be retained between first portion 46 and stop 48. Stop 48 may be retained in aperture 49. Second portion 47 may be coupled to cap 50 so that first portion 46 moves telescopically relative to cap 50 in transverse direction 8. For example, second portion 47 may be received in aperture 54 defined in body 56 of cap 50. Stop 48 may engage with cap 50 to retain second portion 47 in aperture 54. For example, stop 48 may be received in a recess defined by an interior surface of insertion portion 58, thereby holding stop 48 and axle 46 in place relative to cap 50.
(28) Cap 50 is coupled to transverse end 61 of its corresponding support 22. For example, as shown in the illustrated embodiment of
(29) Panels 24 may be coupled the supports 22 by any suitable technique. For example, panels 24 may be frictionally gripped (e.g. by clamps coupled to supports 22), hung (e.g. by hooks coupled to supports 22 engaged in apertures defined in panels 22), retained (e.g. as shown in
(30) In some embodiments, mount 30 comprises a flange 70. Flanges 70 on adjacent supports 22 may abut each other (e.g. while canopy 20 is retracted), thereby spacing apart supports 22 and their corresponding engagement members 32. This may prevent adjacent engagement members 32 from binding, which may occur when engagement members 32 abut and may inhibit movement of engagement members 32 in track 26.
(31) Flange 70 may extend in longitudinal direction 6 and/or other directions extending radially outward (i.e. in directions orthogonal to transverse direction 8) from engagement member 32. For example, in the embodiment depicted in
(32)
(33) In some embodiments, panels 24 may comprise panel retainers 68 having a dimension greater than a dimension of aperture 65. For example, a panel retainer 68 may comprise a cord sewn along an edge of a panel 24, a seam where panel 24 is folded back on itself (to provide additional thickness), a rod attached to an edge of panel 24, and/or any other suitable shape for providing a greater dimension to a portion of panel 24. Second cavity 64 may be open-ended at one or more of its transverse ends 61 (e.g. where mounts 30 are coupled to supports 22), thereby permitting panel retainers 68 to slide into second cavity 64 in transverse direction 8 through opening 63 (see
(34) In some embodiments, aperture 65 has a longitudinal dimension of 0.5 cm (0.2 inches), and panel retainers 68, when positioned inside second cavity 64, have a longitudinal dimension greater than 0.5 cm (0.2 inches).
(35) In some embodiments, canopy 20 comprises a leader 80, by which a user may extend and/or retract canopy 20. Leader 80 provides a coupling mechanism by which one or more supports 22 may be coupled to a mover for moving supports 22. The mover (not shown) may comprise any suitable mechanism for providing force to move supports 22, such as a motor, a person, etc. For example, leader 80 may comprise lead line 80A of
(36) In some embodiments, magnets 72 are coupled to one or more supports 22 for magnetically attracting other supports 22. For example, each support 22 may be coupled to a magnet 72 oriented to attract an oppositely-oriented magnet 72 coupled to an adjacent support 22. Alternatively, or in addition, some supports 22 may be coupled to magnets 72 for attracting adjacent supports 22 which comprise magnetically-attractive materials (e.g. iron, suitable alloys, etc.). Magnets 72 may be discrete objects coupled to support 22 (as shown, for example, in
(37)
(38) Aspects of the present disclosure comprise a kit of parts for assembling canopy 20. Parts of canopy 20, such as supports 22, canopy panels 24, tracks 26, and/or mounts 30 (and/or constituent parts thereof) may be packaged together or separately, coupled or uncoupled, for assembly by a user.
(39) Aspects of the present disclosure provide a method for assembling canopy 20. Such methods may comprise spacing apart tracks 26 appropriately and coupling supports 22 to tracks 26 so that tracks 26 and supports 22 extend in longitudinal direction 6 and transverse direction 8, respectively, as described above. Such methods may further comprise coupling various elements of canopy 20 to each other. For example, the method may comprise coupling mount 30 to a support 22 (e.g. via a retention member 59 and aperture 69) and to track 26 (e.g. via wheel 32A and protrusion 33). The method may comprise coupling the elements of mount 30 (e.g. engagement member 32, axle 41, bias mechanism 40, stop 48, cap 50, flange 70, and/or other elements) together to form mount 30. The coupling of particular elements is described in greater detail above.
