Description of the Related Art

Patio umbrellas are well known. Among patio umbrellas, some designs allow the location of shade cast thereby to be altered by tilting an upper part of the umbrella relative to a lower part of a pole that supports the upper part of the umbrella. Such tilting function can be provided by a hinge disposed along the length of a pole between two pole segments that can be angled to one another.

DETAILED DESCRIPTION

While the present description sets forth specific details of various implementations, it will be appreciated that the description is illustrative only and should not be construed in any way as limiting. Furthermore, various applications of such implementations and modifications thereto, which may occur to those who are skilled in the art, are also encompassed by the general concepts described herein. Each and every feature described herein, and each and every combination of two or more of such features, is included within the scope of the present invention provided that the features included in such a combination are not mutually inconsistent.

FIG. 1A illustrates an umbrella 100. The umbrella 100 can include a canopy assembly 102. The canopy assembly 102 can include plurality of ribs 104 and a plurality of corresponding struts 108. The ribs 104 and struts 108 can provide support to a shade member or canopy fabric. The canopy fabric can provide shade and/or protection from the weather for persons and objects located underneath the canopy fabric. The canopy fabric should be flexible to facilitate folding the canopy assembly 102 and can be formed of canvas, plastic mesh, or other sheet material.

One end of each of the ribs 104 can be pivotably coupled with an upper hub 112. The upper hub 112 can be coupled with a central pole 120. The central pole 120 is generally mounted or supported vertically, and so is sometimes referred to as an upright pole. One end of each of the struts 108 can be pivotably coupled with a lower hub 116. The ends of the ribs 104 and the struts 108 coupled to the hubs 112, 116 respectively are inner ends in that they are closer than the opposite ends thereof to a central axis of the central pole 120 when the canopy assembly 102 is open. The lower hub 116 can be moveably, e.g., slideably, mounted on the central pole 120. An opposite end of each of the struts 108 can be pivotably coupled with a corresponding rib of the ribs 104. The canopy assembly 102, which can also include the hubs 112, 116, can be opened and closed by movement of the lower hub 116 along the central pole 120. The canopy assembly 102 can be opened by raising the lower hub 116 along the central pole 120 from a lowered position in which the canopy assembly 102 is closed. The canopy assembly 102 can be closed by lowering the lower hub 116 along the central pole 120 from a position of the lower hub 116 in which the canopy assembly is open.

The umbrella 100 can include an opening and closing mechanism 136, which can be a first mechanism of the umbrella 100. The opening and closing mechanism 136 is sometimes referred to herein by the shorthand open/close mechanism 136. The opening and closing mechanism 136 can be mounted on, in or partly on and partly in the central pole 120. The opening and closing mechanism 136 can be part of the structure to control the position of the lower hub 116 along the central pole 120. The open/close mechanism 136 can include a crank handle 137 attached to a spool (not shown). The spool can be attached to a tension transferring member (not shown), such as a string, a wire, a cord, or other similar member configured to transfer a force to one or both of the hubs 112, 116 and also configured to be wound on the spool. The cord or other tension transferring member can be coupled at one end with the spool and at an opposite end with the lower hub 116. The cord can pass over a pulley located adjacent to or supported within the upper hub 112. By turning the spool using the crank handle 137 (see FIG. 1B), the winding or unwinding of the cord can correspondingly raise or lower the lower hub 116 and open or close the canopy assembly of the umbrella 100. The elevated position of the lower hub 116 can be held by locking the crank handle 137, which locks the cord, or otherwise locking the cord in place. The crank handle 137 may be locked by sufficient internal friction.

The umbrella 100 includes a tilt mechanism 124. The tilt mechanism 124 can be a dedicated mechanism that is provided to adjust the tilt angle of the canopy assembly 102 or components thereof, as discussed further below. As used herein, a dedicated mechanism is one that can provide only the tilt function as described herein. As used herein, a dedicated mechanism is one that provides the tilt function separate and apart from the open/close function of the canopy assembly. The tilt mechanism 124 can be a dedicated tilt mechanism that performs multiple functions, e.g., providing a tilted configuration from an aligned configuration and locking a portion of the umbrella 100 in a tilted configuration after the tilted portion has been tilted. The tilt mechanism 124 can be mounted along the central pole 120, as shown. The tilt mechanism 124 can also be used in a cantilever-style umbrella. In such an embodiment, the tilt mechanism 124 is disposed about an upright pole disposed to a side of a central portion of a canopy assembly. The tilt mechanism 124, or portions thereof, can be integrated into the opening and closing mechanisms 136 as discussed further below. The tilt mechanism 124 can divide the central pole 120 into an upper pole portion 128 and a lower pole portion 132. The lower pole portion 132 can be a first pole and the upper pole portion 128 can be a second pole and the tilt mechanism 124 can be disposed between and the first pole and the second pole. The tile mechanism 124 can couple the first pole to the second pole. The upper pole portion 128 can be coupled with an upper end or an upper portion of the tilt mechanism 124. The upper hub 112 can be coupled with an upper or portion or upper end of the upper pole portion 128. The lower pole portion 132 can be coupled with a lower end or lower portion of the tilt mechanism 124. Further details of tilt mechanisms for umbrellas are described below as well as in U.S. Pat. Pub. No. 2018/0298632 (Ma) and U.S. Pat. No. 6,446,650 (Ma), which are hereby incorporated herein by reference for purposes of further description of the upper and lower portions of various embodiments of tilt mechanisms and for all other purposes.

The tilt mechanism 124 can have a first configuration, which can be an untilted or aligned configuration as shown in FIGS. 1A, 2A, and 9A. In the untilted or aligned configuration, the upper and lower pole portions 128, 132 can be aligned along the same axis. The tilt mechanism 124 can have a second configuration which can be tilted relative to the first configuration, as shown in FIGS. 1B, 2B, and 9B. In the second configuration, the upper and lower pole portions 128, 132 can form an angle therebetween. The angle can have an apex at a pivot axis of the tilt mechanism 124. The first and the second configurations can both be tilted configurations, with the second configuration being more tilted than the first configuration. The tilt mechanism 124 can adjust between the first and second configurations.

The tilt mechanism 124 can be controlled by an actuator, such as the slideable collar actuator 140, discussed in more detail below. The actuator can have an independent and/or separate control mechanism from the open/close mechanism 136. The actuator can be operable by a person to selectively manipulate the tilt mechanism 124 between the first and second configurations. The actuator cam provide a dedicated control for the tilt configuration of the umbrella 100, being part of a mechanism that is not functionally combined with the opening and closing mechanism 136. A cord or a control rod (not shown) can couple the actuator with the tilt mechanism 124. A first end of the cord or control rod can be coupled with the actuator. A second end of the control rod or cord can be coupled with the tilt mechanism 124, as described further below in relation to the slideable collar actuator 140. Alternative actuators are described in U.S. application Ser. No. 16/826,052 files on Mar. 20, 2020 and included as Appendix A.

As shown in FIGS. 2A-2B, the tilt mechanism 124 can include an upper portion 124a and a lower portion 124b. The upper portion 124a can extend to a position disposed within (e.g., can have an upper terminal end disposed within) a lower end of the upper pole portion 128. The lower portion 124b can extend to a position disposed within (e.g., have a lower terminal end disposed within) an upper end of the lower pole portion 132. The tilt mechanism 124 can include a pivot axis 124c. The pivot axis 124c can be located between an upper terminal end of the upper portion 124a and a lower terminal end of the lower portion 124b. The pivot axis 124c can intersect, e.g., can extend through overlapping parts of the lower portion 124b and the upper portion 124a, e.g., through a part of the lower portion 124b adjacent to the upper terminal end thereof and through a part of the upper portion 124a adjacent to the lower terminal end thereof. The upper portion 124a can be pivotable with respect to the lower portion 124b about the pivot axis 124c. The pivot axis 124c can include a pin or axle and each of the upper and lower portions 124a, 124b can include corresponding flanges and apertures for receiving the pin in a pivotal manner. One of the upper and lower portion 124a, 124b can have a forked configuration including two adjacent projections configured to receive a projection of the other of the upper and lower portions 124a, 124b between the adjacent projections of the forked portion. The upper pole portion 128 can be coupled with the lower pole portion 132 by the tilt mechanism 124.

The lower hub 116 can be disposed over the central pole 120. The central pole 120 can be disposed within a central aperture 116a of the lower hub 116. The central aperture 116a can be sized to receive the central pole 120, with the lower hub 116 slideable over the central pole 120. FIG. 2A shows the lower hub 116 located at the tilt mechanism 124 and FIG. 2B illustrates the lower hub 116 positioned below the tilt mechanism 124. The upright pole 120 can include a stop 228. The stop 228 can be a transverse projection from the upright pole 120. The stop 228 can be located on the upper pole portion 128. The stop 228 can be located just above the tilt mechanism 124 or otherwise form a part of the tilt mechanism 124. The stop 228 can limit the uppermost position lower hub 116 to align with the tilt mechanism 124. As such, the stop 228 can be located to contact an upper edge of the lower hub 116 or an edge or ledge of the hub 116 when a portion of the hub overlaps the pivot axis 124c. For example, stop 228 could come to rest within a portion of the lower hub 116 between the upper edge and lower edge thereof. The stop 228 could be located adjacent to the upper portion 124a or the lower portion 124b of the tilt mechanism 124, e.g., on the lower pole portion 132 adjacent to the lower portion 124b of the tilt mechanism 124.

FIGS. 3-7 further illustrate one embodiment of the lower hub 116. The lower hub 116 can include plurality of outwardly extending projections 212. The projections 212 can be disposed around, e.g., circumferentially spaced around, an outer periphery of an outer portion 214 of the lower hub 116. The projections 212 can be spaced by corresponding recesses 213. The recesses 213 are configured to pivotably receive the struts 108 of the umbrella 100. Inner ends of the struts 108 opposite the outer ends (which are coupled to the ribs 104) are pivotally mounted within the recesses 213.

The lower hub 116 can include an inner portion 218 in addition to the outer portion 214. The outer portion 214 can be disposable about the upright pole 120 and over the tilt mechanism 124. The inner portion 218 can be disposable at least partially within the outer portion 214 and can be moved to various positions over the upright pole 120, e.g., over the lower portion 132 and/or the upper portion 128. As discussed further below, the inner portion 218 of the lower hub 116 can come to rest in an elevated position at which the inner portion 218 is disposed over the lower portion 132 of the upright pole 120. In some embodiments, the inner portion 218 of the lower hub 116 can come to rest in an elevated position at which the inner portion 218 is disposed over the upper portion 128 of the upright pole 120.

The outer surface 218a can extend around at least a portion of an outer circumference of the inner portion 218. The inner portion 218 can include a pivot structure, e.g., including a pivot shaft and/or one, two, or more than two pivot projections 218b. The pivot projections 218b can extend or project outwardly from the outer surface 218a. The pivot projections 218b can comprise curved, e.g., generally cylindrical members. The pivot projections 218b can be aligned with each other on opposite sides of the outer surface 218a along a pivot axis, e.g., spaced 180 degrees apart from each other. The inner portion 218 can include an upper edge 218c, sometimes called an upper rim 218c. The upper rim 218c can extend around at least a portion of an upper end of the outer surface 218a. The upper rim 218c can include an angled edge portion, sometimes called an angled rim portion 218d. The angled rim portion 218d can be at an angle with the rest of the upper rim 218c. The inner portion 218 can include a bottom edge 218e, sometimes called a bottom rim 218e. The bottom rim 218e can extend a circumference of the outer surface 218a. The bottom rim 218e can be located on an opposite side of the pivot projections 218b from the upper rim 218c. The inner portion 218 can include a central aperture 218f. The central aperture 218f can be sized to receive the central pole 120.

The outer portion 214 has a multi-part construction in some embodiments which facilitates assembly. For example, the outer portion 214 can comprise an upper member 215 and a lower member 216. The upper member 215 can be coupled together with the lower member 215 to form the outer portion 214. FIGS. 3 and 4 show that the projections 212 and the recesses 213 can be located partly on the upper member 215 and partly on the lower member 216. In other embodiments, the projections 212 and the recesses 213 could be located entirely on the projection 212 or entirely on the recesses 213.

The channels 216a can have a depth between the inner wall 116b and the radial surface that is at least as great as the length of the pivot projections 218b of the inner portion 218. The channels 216a can include a semi-circular (or other arcuate) end surface. An arcuate (e.g., semi-circular) end surface facilitates the pivoting of the outer portion 214 relative to the inner portion 218 as shown for example in FIGS. 6A and 6B.

The upper member 215 can include one or more trapping members or projections 215a. When the upper member 215 is assembled to the lower member 216, the projections 215a can extend across an interface between the upper member 215 and the lower member 216. The projections 215a can extend parallel with the longitudinal axis of the central aperture 116a. The projections 215a can be sized and aligned to be received within at least a portion of the channels 216a.

The base member 326 can be generally shaped as a cylindrical block. The base member 326 can couple with an end of the driver 322 opposite the end 323. The base member 326 can be disposable within or coupled with the spring 328. The tilt mechanism 124 can include a tension member 329. The tension member 329 can couple with the driver 322 through the base member 326 or directly with the driver 322. The base 322a of the driver 322 can include a projection that couples with the base member 326. The tension member 329 can couple with a link or pin connected with the driver 322. The tension member 329 can include a loop or hook that coupled with the link or pin. The tension member 329 can also loop through an aperture in the base 322a.

The tilt mechanism 124 can include a guide track or channel 324. The channel 324 can be formed in a first channel member 324a and a second channel member 324b. The first channel member 324a can cooperate with the second channel member 324b to form the channel 324. Alternatively, a single channel member can be employed with the channel member 324b disposed therethrough. The channel 324 can include a ramped surface.

The assembly of the tilt mechanism 124 is further illustrated as in FIGS. 9A and 9B. The sleeve 321 can be disposed about the spring 328 and/or the base member 326. The driver 322 (e.g., the base 322a) can be at least partially retractable within the sleeve 321. The sleeve 321 can be disposed within the lower portion 124b and/or the lower pole portion 132. The tension member 329 can be disposed within the lower pole portion 132. The channel 324 (e.g., defined in part by each of the channel members 324a, 324b) can be disposed in the upper portion 124a and/or the upper pole portion 128. The elongate portion of the driver 322 having the end 323 can extend across the interface between the upper portion 124a and the lower portion 124b. The end 323 can be disposed within the channel 324 on an opposite side of the pivot axis 124c from the spring 328. The rollers (or other movement enhancing devices or runners) coupled with or disposed on the end 323 can be engaged with walls within the channel 324.

The lower hub 116 can be raised to align with the tile mechanism 124, corresponding to an open configuration of the umbrella canopy. A cord 138 can extend through a channel within the tilt mechanism 124 and pass through the lower pole portion 132 and the upper pole portion 128 and extend over the pulley of the central pole 120 and return to couple with the lower hub 116. The cord 138 can be used to open and close the umbrella canopy 102 by raising and lowering the lower hub 116. The cord 138 can be coupled at an opposite end with an open/close mechanism, e.g., with a shaft or spool coupled with the crank handle 137.

In the raised position of the lower hub 116, the lower hub 116 can be aligned with the pivot axis 124c. In certain implementations, the pivot axis 124c can be a generally aligned with the axis of the inner projections 218b. In certain implementations, the tilt axis of the lower hub 116 can be located (i.e., either above or below) within ½″, 1″, or 2″ of the pivot axis 124c. In certain implementations, the inner member 218 can be aligned with the pivot axis 124c.

In the second configuration shown in FIG. 9B, the upper pole portion 128 is tilted at an angle relative to the lower pole portion 132 by the tilt mechanism 124. The tilting can be actuated by the driver 322 and the channel 324. The driver 322 can be shifted downward (e.g., by a force on the tension member 329) with the first end 323 moved from a first raised position in the channel 324, to a second lowered position within the channel 324. Due to the ramped surface of the channel 324, the upper portion 124a and the upper pole portion 128 can pivot about the pivot axis 124c relative to the lower portion 124b and to the lower pole portion 132.

In the second configuration, the outer portion 214 of the lower hub 116 can be pivoted relative to the inner portion 218. The pivoting can occur on the tilt axis defined by the inner protrusions 218b within the channels 216a. Engagement of the outer surface 218a with the inner surface 116b can stabilize and steady the tilting motion of the tilt mechanism 124. In certain implementations, the outer surface 218a can be engaged with the lower rim 116c continuously in both the first and second configurations. Pivoting of the upper portion 124a and the upper pole portion 128 is further facilitated by the angled rim portion 218d. The angled rim portion 218d can accommodate a shifted position of the upper pole portion 128 within the central aperture 218f. Without the angled rim portion 218d, the upper pole portion 128 would interfere with the upper rim 218c.

The downward movement of the driver 322 can compress the spring 328. The spring 328 can store strain energy to bias the driver 322 into the upper position with the end 323 biased into the first position within the channel 324 corresponding to the second configuration of the umbrella 100. The driver 322 can be movable by a force applied to the tension member 329 by an actuator, such as the actuator 140. The actuator can be configured for moving the umbrella between the first and second configurations. Upward movement of the driver 322 can return the tilt mechanism 124 to the first configuration.
