[0001] The present invention relates to a portable shelter. The present invention has particular, although not exclusive application to beach shelters and other like outdoor shelters.

BACKGROUND

[0002] The reference to any prior art in this specification is not, and should not be taken as an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.

[0003] AU 2020100586 discloses a beach shelter suitable for windy conditions. The portable shelter includes a bridged frame, and a canopy including a fixed-end extending from the frame. A free-end of the canopy flutters freely in the breeze.

[0004] In practice, the bridged frame can be time-consuming and involved to assemble and/or relocate. The preferred embodiment provides for improved assembly and/or relocation of the shelter.

[0005] Further, in the event that the sun position or wind changes, the bridged frame is difficult to reconfigure to obtain desired shading from the shelter. The preferred embodiment provides for improved reconfiguration.

SUMMARY OF THE INVENTION

[0006] According to one aspect of the present invention, there is provided a portable shelter including: a support including an upright; and a canopy for being supported by the support.

[0007] The canopy may include a free-end for fluttering in the breeze. The support may extend from the ground at a single location which may advantageously result in: improved assembly, and/or relocation of the shelter by simply moving the support to another single location. Alternatively, the shelter may be a hand-held umbrella with a secured canopy.

[0008] The support may be bent so that the canopy can be readily angled, without moving the support from the single location, to obtain desired shading from the shelter in the event that the sun position changes. The support may include a pair of hingedly coupled post members. The support may also be rotated about its axis in the ground. The canopy may be angled in a plane, up to 400 in either direction from vertical.

[0009] The canopy may include an expandable frame, and a sheet of material supported by the frame. The sheet may fold in on itself when the frame is collapsed. The sheet may be permanently affixed to the frame. The frame may expand in a single plane. The frame may include the support.

[00010] The frame may include retractable ribs supporting the sheet. Each rib may be articulated. Each rib may be pivotally expandable. Each rib mayinclude a proximal member, and a distal member pivotally coupled to the proximal member. The proximal member may not be coupled to the end of the distal member. An end of the distal member may be pivotally coupled to a stretcher arrangement. The distal member may fold in toward the proximal member. The frame may include two or four ribs.

.

[00011] The frame may include a stretcher arrangement for stretching out each rib from the support. The stretcher arrangement may include two or more stretchers, and preferably three stretchers. The stretchers may converge when stretching out the rib. The stretcher arrangement may include a first stretcher coupled between the support and the rib. The stretcher arrangement may include a slider for sliding along the first stretcher. A second stretcher may be coupled to the slider. The stretcher arrangement may further include a second stretcher coupled between the first stretcher and a runner for running along the support. The second stretcher may be slidably attached to the first stretcher. The stretcher arrangement may further include a third stretcher coupled between the first stretcher and the support. The third stretcher may be slidably attached to the first stretcher. The third stretcher may be pivotally coupled to the second stretcher.

[00012] The runner may move upward to expand the ribs. The shelter may include a lock for locking the expanded frame. The lock may include a pin for being received in the support and for locking the runner in place.The shelter may include means for rotating the support to suit wind direction. The shelter may further include at least one foot protrusion for engaging with a foot to couple the support in the ground. The protrusion may be retractable. The shelter may include three spaced apart protrusions radially extending from the support. The support may terminate in a screw for screwing into the ground. The shelter may include a depth indicator to indicate that the support is of sufficient depth in the ground

[00013] The shelter may further include a tether for tethering to the support, and an anchor for anchoring the tether. The anchor may include a receptacle for receiving earth.

[00014] According to another aspect of the present invention, there is provided a method for erecting a shelter including: erecting a support including an upright post extending from the ground; and supporting, using the support, a canopy so that its free-end flutters in the breeze.

[00015] According to another aspect of the present invention, there is provided an expandable frame for a portable shelter, the frame including: one or more retractable ribs for supporting sheet material; and a stretcher arrangement for stretching out each rib from the support, the stretcher arrangement including: a first stretcher for coupling between the support and the rib; a slider for sliding along the first stretcher; and a second stretcher for coupling to the slider.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[00024] According to an embodiment of the present invention, there is provided a portable shelter 100 as shown in Figure 1. The shelter 100 has a support 102 including an upright post extending up from the ground at a single location. A collapsible canopy 104 is supported by the support 102 and includes a free-end 106 for fluttering in the breeze.

[00025] The support 102 extends from the ground at a single location which advantageously results in improved assembly with ready erection of the sole support 102. Further, the shelter 100 can be readily relocated by simply moving the support 102 to another single location.

[00026] The canopy 104 includes an expandable frame 108, in turn, including the upper end of the support 102. Further, the canopy 104 includes a sheet of flaccid material 110 which extends from the frame 108 to its fluttering free end 106. The material sheet 110 is permanently affixed to the frame 108, and is expanded in-situ as the frame 108 expands in a single plane during shelter assembly, without the need for separate fastening of the sheet 110 which would otherwise be time-consuming.

[00027] As can best be seen in Figure 1F, the shelter 100 further includes a tether 112 for tethering to the support 102, and an anchor 114 for anchoring the tether 112. The anchor 114 includes a receptacle for receiving surrounding earth, such as sand and rock.

[00028] As can best be seen in Figure 2C, the frame 108 includes an opposed pair of uppermost articulated ribs 200, retractable on either side of the support 102, for supporting the sheet 110. The sheet 110 folds in on itself when the frame 108 is collapsed so that the wet surfaces fold together and any water is contained there between. Each rib 200 is pivotally expandable from the support 102 in two different directions, namely including a pair of pivotally joined rib members 202 with one rib member 202a pivoting in a clockwise direction and the other rib member 202b pivoting in an anticlockwise direction. The weight of the sheet 110 on the distal members 202b biases the ribs 200 toward an expanded configuration.

[00029] As can best be seen in Figure 2D, the frame 108 also includes a stretcher arrangement 204 for expanding the ribs 200 from the support 102. The stretcher arrangement 204 includes a pair of upper stretchers 206 pivotally coupled between an upper runner 208 for running along the support 102 and the ribs 200.

[00030] As can best be seen in Figure 2E, the stretcher arrangement 204 further includes a pair of lower stretchers 210 pivotally coupled between the upper stretchers 206 and a lower runner 212. The runners 208, 212 move toward each other, along the support 102, to expand the ribs 200.

[00031] The shelter 100 includes a lock for locking the expanded frame 108. The lock includes an over-centering arrangement for locking the frame 108 in an expanded configuration when the runners 208, 212 are moved together beyond a certain point.

The lock also includes a pin for being received in the support 212 and for locking at least one of the runners 208, 212 in place.

[00032] Turning to Figures 3 and 4, the bendable support 102 includes a pair of hingedly coupled post members 400a, 400b so that the canopy 104 can be readily angled, without moving the support 102 from the single location in the ground, to obtain desired shading from the shelter 100 in the event that the sun position changes. The support 102 can be rotated about its axis in the ground to accommodate changes in wind, and the expanded canopy 104 can be angled in a plane, up to about 400 in either direction from vertical.

[00033] Turning to Figures 5, the shelter 100 further includes three retractable foot platforms 500 (i.e. protrusions), extending transversely at the base of the support 102, for engaging with a foot to couple the support 102 in the ground. Each lever platform 500 includes a pair of hinged plates, with top plate fixed in position along the support 102, and radially extends transverse the support 102. The support 102 also terminates in a screw tip 502 for screwing into the ground.

[00034] A method for erecting the shelter 100 is now described.

[00035] Initially as shown in Figures 5A to 5C, the support 102 is screwed into the ground which, in turn, pushes against and expands the foot platforms 500. A user can kick the edge of one of the partially expanded lever platforms 500 to further rotate and drive the support 102 into the ground, which hardens with depth, to align the folded material sheet 110 into the wind. Meanwhile, the top end of the support 102 is held for stability. The fully expanded platforms 500 also serve as a dynamic depth indicator to expand and indicate that the support is of sufficient depth in the ground. The fully expanded platforms 500 are stabilizing protrusions for engaging with the adjacent ground surface in wind gusts and stabilizing the support 102 in the ground

[00036] Figure 1A shows the erected support 102 including the upright post extending from the ground in which it is screwed. The support 102 initially supports the retracted canopy 104 so that its free-end 106 flutters in the breeze.

[00037] As shown in Figures 1B to 1E, the runners 208, 212 (see also Fig. 2) are brought together by the user to expand the canopy 104. The lock locks the runners 208, 212 along the support 102.

[00038] As the day goes by, and the wind direction and sun position changes, the support 102 can be: rotated using the platforms 500 as shown in Figure 5, and angled about the hinge as shown in Figure 4, to maintain suitable shade from the canopy 104.

[00039] A similar shelter 100' according to another embodiment is shown in Figure 6.

[00040] Turning first to Figure 6C, the frame 108' includes retractable ribs 200' supporting the sheet 110, as before. Each uppermost rib 200' is articulated and pivotally expandable. Each rib 200' includes a proximal member 202a' pivotally coupled to the top of the support 102 at a fixed hub 600, and a distal member 202b' pivotally coupled to the proximal member 202a'. The proximal member 202a is not coupled to the end of the distal member 202b so there is overlap when the rib 200' is fully expanded (see. Fig. 6E), making it difficult for the shelter 100' to flip inside-out when windy and enabling the shelter 100' to fold down to half the length of a normal shelter. During collapse, the distal member 202b'folds in toward the proximal member 202a, as before. The 1-D frame 200' includes two ribs 200', although can be extended to be a 2-D frame with four evenly spaced ribs 200'for an umbrella.

[00041] Turning first to Figure 6D, a proximal end of the distal member 202b' is pivotally coupled to a stretcher arrangement 204' of the frame 108'. The stretcher arrangement 204' stretches out each rib 200'from the support 102 using three fixed length stretchers 206', 210', 602.

[00042] An intermediate (i.e. first) stretcher 206' is pivotally coupled between the support 102, via a fixed hub 600, and the end of the distal member 202b' of the rib 200'.

[00043] A lower (i.e. second) stretcher 210' is coupled between the intermediate stretcher 206' and a sliding runner 212'for running along the support 102. The lower stretcher 210' is slidably attached to the intermediate stretcher 206', via a tubular slider 604 to which it is pivotally attached. Accordingly, the lower stretcher 210' is pivotally coupled to the slider 604 and the runner 212'.

[00044] An upper (i.e. third) stretcher coupled between the intermediate stretcher 206' and the support 102. The upper stretcher 602 is also slidably attached to the intermediate stretcher 206', via a slider 604 to which it is pivotally attached. Accordingly, the upper stretcher 602 is pivotally coupled to the slider 604 and a fixed hub 600.

[00045] In use, the runner 212' is moved upward to expand the ribs 200' or downward to collapse them with an incredibly easy movement. In pushing the runner 212' up, the slider 604 slides out along the intermediate stretcher 206' and the ribs 200' expand. The upper and lower stretchers 210', 602 converge. The shelter 100' includes a lock for locking the expanded frame 108'with a locking pin in the runner 212' and support 102.

[00046] A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.

[00047] In one embodiment, the runner 208 is replaced by a static hub fixed to the support 102.

[00048] In compliance with the statute, the invention has been described in language more or less specific to structural or methodical features. It is to be understood that the invention is not limited to specific features shown or described since the means herein described comprises preferred forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted by those skilled in the art.
