a second coupling arrangement, slideably coupled to the vertical support member, for coupling the respective first end of each brace member to the vertical support member,
a canopy;
a canopy supporting assembly coupled to the two subframe assemblies, wherein the canopy supporting assembly supports the canopy and provides cover over the area, wherein the canopy supporting assembly comprises:
a first rib pole and a second rib pole,
a first rib pole supporter coupled to the second end of the first arm member of the first subframe assembly;
a second rib pole supporter coupled to the second end of the first arm member of the second subframe assembly;
a third rib pole supporter coupled to the second end of the second arm member of the first subframe assembly; and
a fourth rib pole supporter coupled to the second end of the second arm member of the second subframe assembly;
wherein the first rib pole is supported by the first and second rib pole supporters and the second rib pole is supported by the third and fourth rib pole supporters; and
wherein the canopy is substantially rectangular in shape and comprises:
at one corner of a first end, a pocket for receiving and trapping a first end of the first rib pole;
at the other corner of the first end, an open and closable pocket for facilitating the receiving and releasable trapping of a second end of the first rib pole; and
along substantially the remainder of the first end, an enclosure for enclosing at least a substantial length of the first rib pole therein.
2. The portable shelter as claimed in claim 1 , wherein the canopy comprises:
at one corner of a second end, a pocket for receiving and trapping a first end of the second rib pole;
at the other corner of the second end, an open and closable pocket for facilitating the receiving and releasable trapping of a second end of the second rib pole;
along substantially the remainder of the second end, an enclosure for enclosing at least a substantial length of the second rib pole therein.
3. The portable shelter as claimed in claim 2 , wherein the canopy supporting assembly comprises at least a backbone pole, and wherein the canopy comprises:
at about the middle of a third end, a pocket for receiving and trapping a first end of the backbone pole;
at about the middle of a fourth end, an open and closable pocket for facilitating the receiving and releasable trapping of a second end of the backbone pole.
4. A portable shelter for providing cover over an area, wherein the shelter is coupleable to a structure, the portable shelter comprising:
a first base member and a second base member, each of which are coupleable to the structure and wherein each base member comprises (i) a channel for receiving a portion of the structure and (ii) an elongated leg;
two subframe assemblies, each subframe assembly comprising:
a vertical support member having a first end and a second end, wherein the first end is coupleable to a respective base member;
at least two arm members, each having a first end and a second end, wherein the first end of each respective arm member is pivotally coupled to the second end of vertical support member;
at least two brace members, each having a first end and a second end, each respective first end being coupled to the vertical support member and each respective second end being pivotably coupled to a respective arm member;
a first coupling arrangement for pivotably coupling the respective first end of each arm member to the second end of the vertical support member;
a second coupling arrangement, slideably coupled to the vertical support member, for coupling the respective first end of each brace member to the vertical support member,
a canopy supporting assembly coupled to the two subframe assemblies, wherein the canopy supporting assembly supports a canopy and provides cover over the area
wherein at least:
the elongated leg associated with the first base member is slideably coupled to the vertical support member associated with a first of the two subframe assemblies and the elongated leg associated with the second base member is slideably coupled to the vertical support member associated with a second of the two subframe assemblies,
one of the elongated leg associated with the first base member and the vertical support member associated with the first of the two subframe assemblies is slideably insertable into the other of the elongated leg associated with the first base member and the vertical support member associated with the first of the two subframe assemblies, wherein the elongated leg associated with the first base member and the vertical support member associated with the first of the two subframe assemblies have complementary rectangular cross-sections for the slideable insertion therebetween; and
wherein one of the elongated leg associated with the first base member and the vertical support member associated with the first of the two subframe assemblies has a plurality of apertures spaced apart along at least a first side and along a second side and wherein the other of the elongated leg associated with the first base member and the vertical support member associated with the first of the two subframe assemblies comprises a complementary spring-biased pin that is receivable within each of the apertures to releasably lock the position of the elongated leg associated with the first base member relative to the vertical support member associated with the first of the two subframe assemblies when the spring-biased pin is within one of the apertures; and
wherein the elongated leg associated with the first base member is releasably coupleable to the vertical support member associated with the first of the two subframe assemblies in at least a first orientation and a second orientation;
wherein:
the elongated leg associated with the first base member and the vertical support member associated with the first of the two subframe assemblies is in the first orientation when the spring-biased pin is received within an aperture along the first side, and
