DETAILED DESCRIPTION OF THE EMBODIMENTS

An umbrella 10 in accordance with an embodiment of the present application is illustrated in FIG. 1. As illustrated, the umbrella 10 includes a handle 12 connected to a single pole 14 that supports the canopy 16 via a plurality of folding risers 18 and spars 22. The risers 18 are folded and unfolded via the slidable ring 20 to which they are rotatably attached. When the ring 20 slides up the pole 14, the risers 18 fold out to lift spars 22 and the canopy 16 is extended. When the ring 20 slides back down, the spars 22 fold in toward the pole 14 and the canopy 16 collapses. The risers 18 are rotatably attached to spars 22 that are provided in the canopy 16 to provide support therefore and that extend outward as the risers 18 fold out.
As can be seen in FIG. 2, for example, the risers 18 that extend to the left in FIGS. 1 and 2 are longer than the other risers, such that the canopy 16 is extended to that side. In this manner, the canopy 16 is sufficiently wide to cover two people while only one person holds the handle 12.
In a preferred embodiment, a single button is provided to both open and close the umbrella 10. In addition, a battery powered flashlight is preferably positioned in the handle 12 as well.
FIGS. 3-5 illustrate an alternative embodiment of the umbrella 10 in which the canopy 16 may be opened to different widths. In FIG. 3, the canopy 16 is extended to a first position in which it is suitable for use by a single person. In FIG. 2, the canopy 16 is extended to a second position, wider than the first position, and can be locked into that position. In FIG. 5, the canopy 16 is extended into a third position, similar to that illustrated in FIGS. 1 and 2, and suitably wide for two people. The canopy 16 is preferably lockable in each position.
FIG. 6 is an illustration of a cross section of the pole 14 in which a wire 30 that extends through the pole 14 and out an opening in a top thereof is visible. In this case, the ring 20 is used to apply a force to the wire 30. The wire 30 is, in turn, connected to the risers 18 and is used to pull them outward into the three positions illustrated in FIGS. 3-5. In a preferred embodiment, the ring 20 is lockable in place along the pole 14 to maintain the canopy 16 in the desired positions. When the ring 20 is pulled all the way down, as illustrated in FIG. 6, for example, the canopy will be in the position of FIG. 5 since the risers 18 are fully extended. As the ring 20 is moved up, tension on the wire 30 decreases and the risers 18 begin to fold and the canopy 16 retracts.
FIG. 7 illustrates an alternative embodiment of an umbrella 110 in accordance with another embodiment of the present application. The canopy 116 (See FIG. 15-17, for example) is not illustrated in FIG. 7, however, the canopy is preferably connected to and extends over, or in between, the spars 118. The umbrella 110 is illustrated in FIG. 7 in a closed state. In this embodiment, a main pole 114 is provided in a manner similar to that of the pole 14 described above. A secondary pole 114 a is connected to the pole 114 via a lower collar, or other movable member, 120 a. The secondary pole 114 a is positioned adjacent to the pole 114 and extends substantially parallel thereto in the closed position illustrated in FIG. 7. The secondary pole 114 a is preferably pivotally connected to the shaft 114 at the lower collar, 120 a at pivot point 120 b. A handle 160 may be provided at the bottom of the first vertical pole 114, if desired. See FIG. 14, for example.
An upper secondary collar, or other movable member, 120 is configured to move up and down the pole 114 to raise and lower the spars 118. As the collar 120 slides up pole 114, the spars 118 extend outward into the first open position illustrated in FIG. 8, for example. In this configuration, the spars 118 are spaced sufficiently away from the posts 114, 114 a such that the canopy 116 provides a first area of coverage suitable for a single person. Specifically, the collar 120 and the spars 118 are connected via the risers 119. As the collar 120 moves up the shaft 114, the risers 119 pivot outward to extend the spars 118 up and out to the first open position illustrated in FIG. 8. The spars 118 on one side of FIG. 8 extend out from the first pole 114, while the spars on the other side of FIG. 8 extend out from the secondary pole 114 a. More specifically, these spars extend from the top portion 114 d of the secondary pole 114 a. In a preferred embodiment, a latch 150 (see FIGS. 8-9, for example) on the pole 114 releasably holds the collar 120 in place on the pole 114 to maintain the umbrella 110 in the first open position. While a latch 150 is illustrated, a depression, recess, protuberance or any other suitable stop may be used in place of latch 150. While not explicitly illustrated, a spring may be provided on the pole 114 to aid lifting the collar 120 into place such that the umbrella 110 is in the first open position, as is common in conventional umbrellas. Pressing a button, or other release, preferably in handle 160 of the umbrella 110 may trigger the upward motion of the collar 120 under bias of the spring.
As is illustrated in FIG. 9, however, the umbrella 110 may be opened further to cover an additional user. The collar 120 preferably includes two elements, 220, 222. The first element 220 slides up and down the shaft 114 and is releasably connected to the shaft 114 a. The second element 222 is connected to the shaft 114 a and positioned over the portion of the element 220 that connects to shaft 114 a in the closed position. This second element 222 separates from element 220 to allow for the further expansion of the canopy 116 to provide a second coverage area suitable for covering a second person. The initial stage of this separation is illustrated in FIGS. 9 and 10.
As can be seen in FIG. 10, a pivot point 114 b is provided in shaft 114 a just below the second element 222 of the collar 120. This pivot point 114 b is not visible in FIGS. 7 and 8 since the portion of element 220 connected to the pole 114 a covers it. As noted above, the shafts 114, 114 a remain substantially parallel to each other while the umbrella is in the closed position. This relationship is also maintained in the first open position of FIG. 8. Thereafter, middle section 114 c of the pole 114 a rotates outward relative to the pole 114 between pivot points 120 b and 114 b. The top portion 114 d of the pole 114 a remains substantially parallel to pole 114, however, is separated therefrom as the middle section 114 c rotates.
As noted above, some of the spars 118 are connected to the pole 114 a, while some are connected to pole 114. In the first open position, the poles 114, 114 a are positioned relatively close together such that the area under the open spars 118 is large enough to accommodate a single user. As the umbrella 110 opens further, as is noted above, the top portion 114 d of the pole 114 a moves away from the pole 114. Thus, the area under the spars 118 increases.
The risers 119 are more specifically connected between the first and second collar elements 220, 222 and the spars 118. As illustrated in FIG. 9, once the first open position is reached, the risers 119 and the spars 118 are in their open position. Separating the top portion 114 d of pole 114 a from the pole 114 increases the area under the spars 118. This is accomplished via the scissors, or accordion structure, 140 illustrated in FIG. 11, for example.
The scissors structure 140 is connected between the two poles 114 a, 114. More specifically, the scissors structure 140 is connected on one side to the bracket 122 a and the top portion 114 d of pole 114 a. The second side of the structure 140 is connected to the top of pole 114 and the bracket 122. The brackets 122 a, 122 are mounted above the elements 222, 220, respectively, of the collar 120 on the poles 114 a, 114. The brackets 122 a, 122 are mounted on the poles 114 a, 114, respectively, such that they are slidable up and down the poles to allow for expansion of the scissors structure 140, as illustrated in FIGS. 11 and 12, for example. As illustrated, as the scissors structure 140 expands laterally to space the top portion 114 d of the pole 114 a away from the pole 114, the brackets 122 a, 122 slide up the poles 114 d, 114.
In one embodiment, the brackets 122 a, 122 may be spring loaded to separate when desired. The brackets 122 a, 122 are preferably connected to each other while the umbrella 110 is in the closed position of FIG. 7 and the first open position of FIG. 8. In one embodiment, illustrated in FIG. 10, for example, a pin 322 a extends out from the bracket 122 a into a receptacle 322 b formed in the bracket 122. The pin 322 a preferably includes a notch that mates with a release trigger, or latch within the bracket 122 to latch the brackets together. This latch is releasable when desired, via a button in the handle of the umbrella 110, for example, or any other suitable release. Once released, the brackets 122 a, 122 are separable from each other, and thus, separate the top portion 114 d of the pole 114 a from the pole 114. A spring (not shown) may be provided to bias the brackets 122 a, 122 away from each other after the latch is released. In another embodiment, the pin 322 a is simply fit into the receptacle 322 b, with no notch or latch mechanism.
Alternatively, or in addition, movement of the lower collar 120 a up the shaft 114 may be used to urge the bracket 122 a away from the bracket 122 as is illustrated in FIG. 11, for example. As the collar 120 a moves up pole 114, the middle portion 114 c of the shaft 114 a pivots outward to extend the top portion 114 d of the pole 114 a further away from the pole 114 in the lateral direction. Similarly, movement of the lower collar 120 a down the pole 114 will pull the bracket 122 a toward bracket 122 to return the umbrella 110 to the first open position.
As illustrated in FIG. 12, the scissors structure 140 expands to a second open position where the top portion 114 d of the pole 114 a is separated from the pole 114 by a maximum distance D. The lower collar 120 a is preferably releasably held in place in the second open position via a latch 152 on the pole 114, in a manner similar to the collar 120, noted above. Alternatively, a slot, recess, depression, protuberance or other stop may be provided on the pole 114 to resist downward movement of the collar 120 a, as desired. The canopy 116 includes additional material that will cover the expanded area between the poles 114 a, 114 such that in the second open position, illustrated in FIG. 12, the entire area under the spars 118, including the area under the scissors structure 140 is covered by the canopy. Additional support spars 118 a, not connected to the poles 114 a, 114 may be provided in the canopy to provide support in this expanded area, if desired. See FIG. 14, for example. The spars 118 a may be supported by support members 142 on the top of the scissors structure 140 (See FIGS. 11-12, for example). As a result, the canopy 116 will cover at least two users in the second open position.
FIG. 13A is a more detailed view of the lower collar 120 a, the collar 120, including elements 220, 222 and the brackets 122 a, 122 in the closed position and in the first open position. As illustrated, the collar element 222 may also include a pin 222 a that fits in a receptacle 220 a formed in the collar element 220. A notch is illustrated formed on the pin 222 a which may be used to latch the collar elements together, if desired, in a manner similar to that described above with respect to brackets 122 a, 122. A spring (not shown) may also be provided to bias the brackets 122 a, 122 away from each other. In another embodiment, the notch may be removed from the pin 222 a.
FIG. 13B illustrates the same elements of FIG. 13A at the point where the umbrella 110 begins to move from the first open position to the second open position, as illustrated in FIGS. 9-10, for example. That is, FIG. 13B shows a more detailed view of the brackets 122 a, 122, collar elements 222, 220 and lower bracket 120 a, as the umbrella 110 begins to transition from the first open position of FIG. 8 to the second open position of FIG. 12.
In another embodiment illustrated in FIG. 14, additional scissors structures 140 a, 140 b may be provided between opposing risers 119 connected to the posts 114 d, 114. The additional scissors structures 140 a, 140 b help to support the spars 118 a provided in the expanded section of the canopy, for example.
FIG. 15 illustrates the umbrella 110, with the canopy 116 connected to the spars 118 in the closed position. FIG. 16 illustrates the umbrella 110, with the canopy 116 in the first open position. FIG. 17 illustrates the umbrella 110 with the canopy 116 in the second open position.
In a preferred embodiment, the umbrella 10, 110 is movable between the closed position, first open position and second open position automatically. It is common for conventional umbrellas to be openable upon pressing a button in the handle, as is noted above. This button releases a latch and allows the canopy, which is typically biased in the open position via a spring to open. As is noted above, a similar arrangement may be provided in the umbrella 10, 110 to move the umbrella into the first open position from the closed position.
As is also noted above, a spring may also be provided between the first and second elements 220, 222 of the first collar and/or the first and second brackets 122 a, 122. Once the latch holding them together is released, they will separate by action of the spring to open the umbrella to the second open position. The latch is preferably also released by operation of a button, or other release in or near the handle 160. While springs are commonly used to move the canopy, any suitable actuator may be used, including but not limited to electric motors and/or hydraulic pistons.
While the umbrella 10, 110 of the present application is illustrated as a hand held rain umbrella, it is not limited to this embodiment and may be a beach umbrella, or patio umbrella for example. In addition, additional open positions may be provided to extend the coverage of the umbrella in multiple directions. That is, the umbrella may be extendable to additional open positions in additional directions to further extend the coverage area provided under the canopy 116. This would be particularly useful when the umbrella is a beach or patio umbrella.
Accordingly, the umbrella 10, 110 of the present application includes at least two open positions, which allow a user to use it for one person, or two people, as they desire. In the first open position, the canopy 16, 116 opens to cover a single, user. In the second open position, the canopy 16, 116 extends to cover at least one additional user.
Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art.
