Abstract

A shelter having at least two spaced parallel longitudinal support rod members coupled to a sheet with the sheet carrying at least one transverse support rod members which assists in maintaining the longitudinal support rod members in spaced relation and in which the sheet and each transverse support rod member are slidable as a unit longitudinally relative the longitudinal support rod members. The longitudinal rod members may be rigid or flexible but preferably form an arched configuration. The longitudinal rod members are preferably received in elongate continuous sleeves coupled to the sheet but various other members for coupling may be provided including discrete sleeve segments or spaced loops.

Claims

1. A portable shelter comprising:

a trapezoidal sheet of fabric with parallel first and second sides and with first and second ends;

a first elongate longitudinal support rod member having a first end and a second end;

a second elongate longitudinal support rod member having a first end and a second end;

at least one elongate transverse support rod member having a first end and a second end;

first sleeve means disposed along the first side of the sheet;

second sleeve means disposed along the second side of the sheet;

the first longitudinal support rod member coupled to the sheet received in the first sleeve means for sliding therein parallel the first side;

the second longitudinal support rod member coupled to the sheet received in the second sleeve means for sliding therein parallel the second side;

each of the first and second longitudinal support rod members having their first and second ends extending beyond the first and second ends respectively of the sheet to support the shelter;

each transverse support rod member having its first end coupled to the sheet adjacent the first side and its second end coupled to the sheet adjacent the second side and extending therebetween transversely relative the first and second longitudinal support rod members to maintain the first and second longitudinal support rod members in spaced relation;

the first and second ends of each transverse support rod member coupled to the sheet independently of the first and second longitudinal support rod members such that the sheet with each transverse support rod member coupled thereto may slide longitudinally relative to the first and second longitudinal support rod members.

2. A shelter as claimed in claim 1 wherein the sleeve means comprises a first sleeve extending along the first side of the sheet and a second sleeve extending along the second side of the sheet.

3. A shelter as claimed in claim 2 wherein each of first and second sleeves comprise a portion of the fabric folded back upon itself and secured to itself.

4. A shelter as claimed in claim 1 wherein the longitudinal support rod members comprise flexible resilient rods biased to assume a straight configuration and adapted to be bent to assume various arched shapes.

5. A shelter as claimed in claim 4 wherein the resilient rods comprise flexible fibreglass rods.

6. A shelter as claimed in claim 5 wherein each transverse support rod member comprises a plurality of separate similar segments removably connectible by a short portion of each segment at one end being telescopically received within a short socket at a second end of an adjacent segment.

7. A portable shelter as claimed in claim 4 including:

a first tensioning member having a first end for securing to the first end of the first longitudinal support rod member and a second end for securing to the second end of the first longitudinal support rod member to maintain the first and second ends of the first longitudinal support rod member a fixed distance apart with the first longitudinal support rod member bent in an arched shape; and

a second tensioning member having a first end for securing to the first end of the second longitudinal support rod member and a second end for securing to the second end of the second longitudinal support rod member to maintain the first and second ends of the second longitudinal support rod member a fixed distance apart with the second longitudinal support rod member bent in an arched shape.

8. A portable shelter as claimed in claim 4 wherein the ends of the first and second longitudinal support rod members are engaged in the ground with the first and second longitudinal support rod members bent in similar arched shapes.

9. A shelter as claimed in claim 1 wherein the longitudinal rods comprise a plurality of separate similar segments removably connectable by a short portion of each segment at one end being telescopically received within a short socket at a second end of an adjacent segment.

10. A shelter as claimed in claim 9 wherein each segment is a hollow tube and is connected to its adjacent segment by a length of elastic cord extending through the hollow tubes.

11. A shelter as claimed in claim 1 wherein the longitudinal support rod members comprise rigid rods having identical generally arched configurations.

12. A shelter as claimed in claim 1 including a pair of pocket members on the sheet for each transverse support rod member;

a first pocket member of each pair secured to the sheet adjacent the first side of the sheet and having an opening directed towards the second side of the sheet adapted for receiving a first end of the transverse support rod member;

a second pocket member of each pair secured to the sheet adjacent the second side of the sheet and having an opening directed towards the first side adapted to receive the second end of the transverse support rod member;

wherein with the transverse support rod member having its first and second ends received in the first and second pocket members of each pair, the transverse rod member tensions the sheet member transversely between the first and second longitudinal support rod members.

13. A shelter as claimed in claim 1 wherein a pair of attachment members is provided on the sheet for each transverse support rod members;

a first attachment member of each pair secured on the sheet adjacent a first side of the sheet and adapted for receiving a first end of the transverse support rod member;

a second attachment member of each pair secured on the sheet adjacent a second side of the sheet and adapted to receive a second end of the transverse support rod member;

wherein with the first and second ends of the transverse support rod member engaged with the first and second attachment members respectively, the transverse support rod member tensions the sheet member transversely between the first and second attachment members.

14. A shelter as claimed in claim 13 wherein the attachment members comprise a pair of socket members with a first socket member having an opening directed towards the second end adapted to receive the first end, of the transverse support rod member and a second attachment member comprising a second socket member directed towards the first side and adapted to receive the second end of the transverse support rod member.

15. A shelter as claimed in claim 14 wherein said first and second socket members comprise first and second grommets each having an opening therethrough;

each transverse support rod member having at each of its ends, a reduced diameter pin portion extending axially from an enlarged shoulder;

each pin portion sized to pass through the opening in the grommets and each shoulder sized be larger than the opening in the grommets.

16. A shelter as claimed in claim 14 wherein each of the first and second ends of the transverse support rod member comprising a hollow tube with an end opening and the first and second attachment means comprising an elongate pin coupled at one end to the sheet and having a second end to be received within the tube in each end of the transverse support rod member.

17. A shelter as claimed in claim 1 including a third elongate longitudinal support rod member secured to the sheet between the first and second longitudinal support rod members parallel thereto received in a third sleeve means coupled to the sheet.

18. A shelter as claimed in claim 1 including a plurality of said elongate transverse support rod members of the same length.

19. A portable shelter as claimed in claim 18 wherein the sheet is rectangular, the support rod members are of the same length and the sheet is of a length substantially less than the length of the longitudinal support rods wherein the sheet may slide between a first position with the first end of the sheet proximate the first end of the longitudinal support rod member and a second position with the second end of the sheet proximate the second end of the longitudinal support rod member.

20. A portable shelter as claimed in claim 1 wherein said fabric comprises a light weight fabric of nylon and each of said longitudinal support rod member and transverse support rod members comprising flexible fibreglass rods.
