The base 60 has a top surface 100 that comprises a first opening 104 disposed on one side of one of the grooves 40 and a second opening 108. The second opening 108 is disposed on the base 60 such that the groove 40 is disposed between the first opening 104 and the second opening 108. The first opening 104 and the second opening 108 extends into the base 60. The openings 104, 108 extend to an elevation below the pin retention recess 84 formed in the base 60. FIGS. 3 and 3A shows that the openings 104, 108 intersect and extend thorough the pin retention recess 84. As discussed further below, a blocking member can be inserted into the openings 104, 108 such that when positioned in one of the openings 104, 108 the blocking member encloses a portion of the pin retention recess 84. The portion of the pin retention recess 84 that is enclosed can be disposed away from a side of the base 60 that receives the ribs. As a result, the blocking member can prevent the rib from slipping out of the mount 30.

FIGS. 3B show the pin retention recess 84 in more detail. In particular, the pin retention recess 84 includes a slot 120 that has an opening 124 on a side surface of the base 60. An enclosed end 132 of the slot 120 is disposed within the base 60. The enclosed end 132 is disposed away from the opening 124 such that a length of the slot 120 is disposed between the opening 124 and the enclosed end 132. One side of the slot 120 is open to the groove 40.

The slot 120 includes a constricted portion 136 adapted to secure a portion of a rib such that the rib can be retained in the groove 40 prior to securing the cover to the base. In one embodiment, the slot 120 includes an expanded portion 140. The constricted portion 136 is disposed, in one embodiment, between the expanded portion 140 and the groove 40 on the base 60. FIG. 3C shows that in one embodiment each of the slots 120 has a C-shaped or inverse C-shaped perimeter in a cross-section taken perpendicular to the length of the slot 120. In one embodiment, only one of the slots 120 on the opposing walls 72 of a grooves 40 has a C-shaped or inverse C-shaped profile and the slot on the opposing wall can have a constant height from the wall 72 into the base 60 in a direction away from the groove 40.

FIG. 3C shows that the pin 88 can have a non-cylindrical shape. For example the rib 34 can have an elongate member 90 that extends between the first end 92 and a second end (not shown). The pin 88 extends from the first end 92 of the elongate member. The pin 88 can have a first perimeter 200 at a first location adjacent to the first end 92 of the elongate member 34 and a second perimeter 204. The second perimeter 204 is at a second location disposed laterally of the first location. The second perimeter 204 is larger than the first perimeter 200. If both ends of the pin 88 have this arrangement, the pin 88 may be described as I-shaped and the coupling of the rib 34 with the base 60 is an I-shaped engagement therebetween. The rib 34 is secured in the base 60 by disposing the first location of the pin 88 in the constricted portion 136 of the slot 120 and the second location of the pin 88 in the expanded portion 140 of the slot 120 as illustrated in FIG. 3C.

FIG. 3E is a schematic view of one opposed wall 72 of one groove 40 of another embodiment of the base 60A. The base 60A can have all the other features of the base 60 including being configured to couple with the cap 64. FIG. 3E shows that a slot 220 can be provided that includes a constricted portion 224 disposed along the length thereof between an opening 228 and an enclosed end 232 of the slot 220. Upper and lower portions of the slot 220 converge toward each other in a direction from the opening 228 to the enclosed end 232. In this embodiment, the rib 34 can be configured such that the pin 88 is cylindrical. The pin 88 need not have an enlarged portion toward the lateral end of the pin. In some embodiments, the pin 88 can be cylindrical with a constant radius along the length thereof. In other embodiments, the pin 88 can have enlarged ends, such as an I-shaped profile. The convergence of the upper and lower portions of the slot 220 can result in the gap between the upper and lower portions being reduced along the length of the slot 220. The reduction of the gap can result in the gap being less than the diameter or minor axis if the pin is non-circular of the pin 88. As a result, to move the pin 88 from the opening 228 to the enclosed end 232 may be achieved by an increased force in the direction from the opening 228 to the enclosed end as the gap reduces. In one embodiment, the constricted portion 224 is deformed or compressed by the pin 88 as the pin passes through the narrowest part of the constricted portion 224. Once the pin 88 passes through the narrowest portion of the gap between the upper and lower portions the pin 88 moves to the enclosed end 232. Once in this position, extracting the pin 88 from the enclosed end 232 requires at least the increased amount of force. As a result the pin is at least temporarily retained in the slot 220, e.g., during assembly until the cap 64 is placed over the base 60 as discussed further below. When so placed a projection 308 of the cap 64 encloses the slot 220 trapping the pin 88 in the enclosed end 232. The constriction of the slot 220 provides for temporary securement of the pin 88.

The base 60 also provides at least some temporary securement of the pin 88 and a rib coupled therewith. FIG. 3B shows that a top of the slot 120 can be aligned with a top surface of the mount 30. The lower edges of the slot 120 can be sloped resulting in a narrowing of the slot from the opening 124. As a result, the pin 88 can be retained by an inflection point P of the lower edge of the slot 120. The inflection point P would be at an elevation higher than the adjacent perimeter between the inflection point P and the enclosed end 132.

FIGS. 2-4 illustrate the cover 64 and how it couples with the base 60 to secure the rib 34 in the upper mount 30. The cover 64 has a top surface 300 and a bottom surface 304. A plurality of projections 308 that have a first end fixed to the bottom surface 304 of the cover 300 and a second end disposed away from the bottom surface 304. In one embodiment, the plurality of projections 308 on the cover 64 comprises a first projection 308A and a second projection 308B. The projections 308 can be integrally formed with the bottom surface 304. The projections 308 can be all substantially the same in configuration. In certain figures the projections are labeled with separate reference numbers to show how they act on opposing sides of the pin 88, but can still be substantially the same in their form but disposed in spaced apart locations. One of the projections 308 is configured to enclose a portion of the retention recess 84. In certain embodiments one of the projections 308 is configured to block one end of the pin 88. As discussed above, the openings 104, 108 extend into the base and intersect the slot 120. FIG. 3D shows that when the projections 308A, 308B are positioned in the base 60 the projections extend through the slot 120 fully enclosing a portion of the slot between the projections 308A, 308B and the enclosed end 232. In some embodiments, one or a plurality of projections 312 are disposed on the bottom surface 304 of the cover 64 and is configured to secure the cover 64 to the base 60.

The first and second projections 308A, 308B are positioned on the cover 64 such that when the cover 64 is coupled with the base 60 the first projection 308A is disposed in the first opening 104 and the second projection 308B is disposed in the second opening 108. The first projection 308A encloses a first pin retention feature 84 and the second projection 308B encloses a second pin retention feature 84. FIG. 3 shows that the first opening 104 and the first retention feature 84 are disposed on or in one of the opposed walls 72 of one of the grooves 40 and the second opening 108 and the second retention feature 84 are disposed on or in the other of the opposed walls 72 of the same groove 40.

In one embodiment, the plurality of projections on the cover comprises a third projection 312 having a first end fixed to the bottom surface 304 of the cover 64 and a second end disposed away from the first end. The second end is adapted to couple with the base 60 in a manner preventing removing the cover 64 from the base 60. The cover 64 can comprise a groove 320 defined between a first projection and a second projection. The groove 320 is located on the cover 64 to be disposed over the groove 40 located on the base. The groove 320 extends through the bottom surface 304 to the top surface of the cover 64 to allow a rib of the frame 14 to rotate to a position disposed at least partially above the upper mount 30.

The upper mount 30 and the moveable mount 38 can be configured with a flush configuration when the base and cover are coupled together. For example, the base 60 can have a recessed portion 324 or area in the upper portion thereof. The recessed portion 324 can be surrounded by side walls 328 that have a height that is equal to or greater than the thickness of the cover 64. Where the thickness of the cover 64 is about the same as the height of the walls 328, a flush configuration is provided. Further, because the projections 308, 312 extend from a bottom surface of the cover 64 the top surface of the cover can be free of openings for screws or other fasteners. This provides not only a flush and attractive appearance, but also prevents water or debris from being lodged therein, which results in a better looking device that is also longer lasting. Also, the cover 18 can be stretched over the upper mount 30 in some embodiments. Accordingly, having a smooth flush surface can provide the advantage of reducing wear of the cover 18 in the location over the mount 30.

The upper mount 30 has a number of advantages. As discussed above, the base 60 is configured to retain the rib 34 therein prior to coupling the cover 64 with the base 60. See FIGS. 3B and 3C. As a result, a plurality of ribs 34 can be coupled with the base 60 prior to full assembly of the upper mount 30. The base 60 also is configured to temporarily retain the pin 88 and the ribs 34 in in the slot 120 by virtue of a C-shaped arrangement of the slots 120. In particular the C-shaped slots 120 oppose tilting of the ends of the pins 88 and thus control a degree of freedom of the ribs 32. If the pins 88 have an I-shaped configuration, then both ends of the pin oppose tilting of the pins 88 and the ribs 32 in the groove 40. The length of the slot 120 prevents short axial shifting of the rib from dislodging the rib 34 from the base 60. In certain embodiments the enclosed end 132 of the slot 120 has an inflection point P where the enclosed end 132 extends downward from the slot 120. The inflection point P can also allow the pin 88 to rest in a concave area. The inflection point P can oppose even small axial movements under the typically small forces that may arise in manufacturing. Full assembly of the cover 64 with the base 60 results in the projections 308A, 308B of the cover 64 of the upper mount 30 blocking egress of the ribs 34 from the base 60. Because the projections 308A, 308B extend through bulk portions of the opposed walls 72 both above and below the slots 120 the projections have a great deal of reinforcement and will not yield even under higher than normal forces.

If the slot 120 is one that converges along the axis thereof as in FIG. 3E, a preliminary securement between the base 60A and the rib 34 is provided by having to move the pin 88 of a diameter larger than the smallest gap in the slot 220 through the smaller gap. As such, the pin 88 is initially retained in the base 60 prior to securement of the cover 64 with the base 60A.

The upper mount 30 is configured such that the cover 64 is manually coupled with the base 60 by inserting the projections 308, 312 into corresponding openings in the cover. The projections 308A, 308B are inserted into the openings 104, 108. The projections 312 are inserted into separate openings 350. The opening 350 and the projections 312 are disposed on the cover 64 such that the projections 312 are aligned to each of the openings 350. The projections 312 can have a hook-like feature on a free end 362 of the projection 312. The hook-like feature can include a lateral projection facing the bottom surface 304 of the cover 64. The lateral projection can be placed against a corresponding surface 368 in the base 60. An advantage of this design is enabling the base 60 and the cover 64 to be secured by a single insertion motion. A highly secure configuration can be provided by increasing the number of projections 312 from one to a plurality of projections. An embodiment with four projections 312 would be particularly secure. Apertures 370 can be provided in the base 60 such that the projections 312 can be accessed to allow them to be disengaged from the surface 368 of the base 60 for disassembly of the mount 30. The projection 312 can initially be deflected upon insertion of the cover 64 into the base 60. The projection 312 can be resilient such that it returns to a less or un-deflected configuration when it reaches the aperture 370. At this point the lateral projection of the hook-like feature can face the corresponding surface 368.

FIG. 4 shows another embodiment of an upper mount 380. The upper mount 380 includes a smaller recessed surface 324A in the base 385. A cover 384 of the upper mount 380 also has a smaller area than the cover 64. The area of the cover 384 is limited to providing connection between and structural integrity among the projections 308 and the projections 312. The cover 384 has a first lateral portion with a plurality of projections 312 and a second later portion with a plurality of projections 312. A narrow section 386 is provided between the first and second lateral portions. One advantage of the upper mount 380 is that a portion 387 of the base 385 is not recessed. The portion 387 provides a thicker area of material disposed over the leg 22. The thicker are of the portion 387 can enhance the weight bearing area of the upper mount 380.

FIGS. 5-9 illustrate embodiments of the moveable mount 38 in further detail. The moveable mount 38 has features that are the same or analogous to those of the upper mount 30 described above. Any and all such features are incorporated into the description of the moveable mount 38 set forth herein.

The moveable mount 38 includes a space 400 formed in the base 402 of the mount 38 extends from a lower surface 403 of the base 402 to an upper surface 405 of the moveable mount 38. That is, the space is a channel that extends entirely through the moveable mount 38.

A cover 404 of the moveable mount 38 has a different configuration than the cover 64. For example, to accommodate the space 400 extending entirely through the moveable mount 38 the cover 404 has less coverage of the top of the base 402. One side 406 of the cover 402 partly defines the space 400. FIG. 8 shows that the side 406 includes contact features 410 that extend in the direction of movement of the moveable mount 38. The features 410 comprise edges that reduce the contact area of the moveable mount 38 with the leg 12 and thus reduce friction in the sliding contact. The edges may provide line contact.

FIG. 7 shows that in one embodiment, the cover 404 comprises a first lateral portion 408, a second lateral portion 412, and a central portion 416 disposed between the first and second lateral portions 408, 412. A first cover groove 420 disposed between the first lateral portion 408 and the central portion 416 and a second cover groove 424 disposed between the second lateral portion 412 and the central portion 416. A third cover groove 428 extends through the cover between the first and second cover groves 420, 424. Each of the first lateral portion 408, the second lateral portion 412, and the central portion 416 comprises projections extending therefrom. The first, second and central portions 408, 412, 416 can comprise general regions of an otherwise continuous expanse of the cover 404.

FIG. 9 shows that the base 402 can have one or a plurality of contact features 420. The contact features 420 can be disposed along the space 400. The contact features 420 can be disposed parallel to the direction of movement of the moveable mount 38 along the leg 22. The contact features 420 can include edges that provide line contact along the leg 22. In other embodiments a low friction insert can be placed in the space 400 to be disposed between the mount 38 and the leg 22.

In one embodiment, the mount 38 can have a securement feature 430 disposed thereon. The securement feature 430 can enable the moveable mount 38 be positioned at any of select positions along the leg 22. For example a plurality of holes can be formed long the leg 22. A pin 434 can be inserted through the feature 430 and through one of the holes in the leg to hold the moveable member 38 at the selected elevation.

FIG. 10 shows another embodiment of a moveable mount 450. The mount 450 includes a cover 454 and a base 456 that partly defines a space 458 for movement along the leg 22. The cover 454 includes a smooth surface 460 disposed opposite contact features 420. In contrast the cover 408 can have contact features as discussed above.

The upper mount 30 can be secured to a plurality of ribs 34 in the following methods. FIG. 3 shows the rib 34 disposed away from the base 60. By a motion in the direction of the arrow A, the rib 34 is inserted into one of the grooves 40. The pin 88 of the rib 34 can have an I-shaped profile as illustrated in FIGS. 3C. The C-shaped slots 120 cooperate with the I-shaped pin 88 to constrain one or multiple degrees of freedom once the pin 88 is initially inserted into the slots 120. The insertion of the pin 88 continues toward the inflection point P. After the pin 88 reaches the inflection point P the pin 88 settles into the concave area below the inflection point P. See FIG. 3B. This provides at least a temporary rib retention function during additional assembly. If the constricted passage configuration of FIG. 3E is used, then the pin 88 is directed through the constricted portion 224 by an increasing force as the walls approach each other. Assembly can continue with additional ribs in the other grooves 40 of the mount 30 if present. Once the rib or ribs are installed, the cover 64 can be moved to a position over the top of the base 60 as in FIG. 3. The projections 308, 312 are aligned with corresponding apertures in the base 60. The cover 64 is advanced relative to the base 60, with the projections sliding in the corresponding openings. The projections 308A are aligned with the apertures 104 and the projections 308B are aligned with the apertures 108. The projections 312 are aligned with the apertures 350. Full advancement causes the projections 308 to span the slots 120 as shown in FIGS. 3B and 3D. The projections 312 also are positioned such that the free ends 362 are disposed on the surfaces 368, resisting removal of the cover 64. In this position the cover 64 may be received in the recessed space 324 such that the top surface thereof is flush with the top of the side walls 328.

The rib 42 can be assembled to the moveable mount 38 in substantially the same way. For example, the rib 42 can be inserted as indicated by the arrow B. The initial retention of the rib 42 in one of the grooves 40 can be in the same manner as discussed above in connection with the rib 34. For example, the pin 88 can be I shaped and the slots 120 can be C shaped. An inflection point P can be disposed between an enclosed end 132 of the slot 120 and the opening 124 to the slot 120. If the constricted passage configuration of FIG. 3E is used, then the pin 88 is directed through the constricted portion 224 by an increasing force as the walls approach each other. Thereafter the cover 404 is secured to the base 402 in much the same manner discussed above.

FIGS. 11-14 illustrate various ways in which the embodiments discussed above can be incorporated into an umbrella. A top notch or upper hub 500 is provided that has a base 504 and a cover 508. The upper hub 500 is one form of an upper mount. The base can include features of the base 60. Such features are incorporated here into this description in their entirety where not inconsistent. The base 504 is symmetric about an axis A that extends along a direction of an umbrella pole that would extend through a central aperture 512 thereof. An umbrella pole is another example of a ground support.

The base 502 has a plurality of grooves 516 disposed around the outer periphery thereof. The grooves 516 are suitable for pivotably coupling with a rib 518. Pin retention recesses 524, which can include a slot similar to the slot 120 or the slot 220 discussed above or similar features, are disposed in or on opposed walls within the base 504. Opposed walls 517 of the hub 500 can define the grooves 516. Projections 520 that have a fix end on a bottom surface of the cover 508 and a free end projecting away from the fixed end are disposed across the pin retention recesses 524 in a way similar to that discussed above. As such the projections 520 provide robust retention of the pin 88 of the rib 518. Securement of the cover 508 to the base 504 can be provided by hook-like projections 532. The projection 532 can be similar to the projections 312 discussed above. The description of these features and their connection to the base of the mount 30 are relevant and are incorporated here. The projections 532 can engage a surface 536 disposed in or on an opening in the base 504.

FIG. 13 shows that the recesses 524 can have a funnel-like configuration. That is the slots can be wisest at an opening disposed on the outer periphery of the 500 and can taper inwardly toward a central portion of the recess 524. One or both of the surfaces defining the recesses 524 can taper inwardly. A constricted portion can be formed by this narrowing. The constricted portion can be about the same size as the diameter of the pin 88, e.g., of the smallest diameter of the pin 88.

FIG. 14 shows assembly of the hub 500. In particular, the rib 518 is inserted into the hub such that a first end of the rib 518 is in the groove 516. The pin 88 is disposed in the pin retention recess 524, e.g., in a slot similar to the slots 120, 220. A rib may be positioned in each of the grooves 516. Projections 520, 532 are inserted into openings in the base 504. The projections 520 enter opening 540 and are advanced to block the enclosed end of the recess 524 preventing the pin 88 from coming out of the hub 500. The projections 532 of the cover 508 enter opening 542 and are advanced to engage a surface in the base 504 preventing disengagement of the cover 508 from the base 504.

FIGS. 15-16 show a runner 600. The runner 600 is a moveable mount and is in some respects similar to the moveable mount 38 discussed above in the context of a pavilion. The runner 600 is similar to the upper hub 500 in some respects. Analogous features of the devices are incorporated by reference here.

The runner 600 includes a base 604 and a cover 608. Grooves 612 are formed in the cover 608 to pivotably couple with ribs. Pin retention recesses 616 extend from an outer periphery of the cover 608 hub to an enclosed end disposed within the cover 608. Projections 620 on the base extend up into opening 624 the cover and are disposed across the pin retention recesses 616. The projections 620 block egress of a pin of an umbrella rib when the rib is installed in the hub 600 and the cover 608 is coupled with the base 604. Fastening projections 626, which can be hook-like in their configuration, project form the base 604. The projections 626 are received in opening in the cover 608. When so inserted the projections engage the cover 608 in a manner similar to that discussed above.

Assembly of the runner 600 proceeds in a manner similar to the assembly method discussed above.
