Abstract

An expandable device including: a first member; a second member; at least one tension member attached to the first and second members and extending between the first and second members, the first and second members movable between an open position, in which at least a part of the first member is spaced from the second member, and a closed position, in which said at least a part of the first member is adjacent the second member; and at least one spacer sized to be located between the first and second members when in the open position, and to maintain the first and second members in the open position, wherein, in the open position, the at least one tension member is held taut between the first and second members.

Claims

1. An advertising assembly movable between an expanded configuration and a collapsed configuration, the advertising assembly including:

a first substantially planar end member;

a second substantially planar end member;

at least one display panel attached to and extending between an outer periphery of the first end member and an outer periphery of the second end member; and

a spacer positionable such that at least part thereof extends between opposing sides of the first and second end members to maintain the assembly in the expanded configuration, the end members configured to receive or engage the spacer centrally, the spacer including a first rod and a second rod joined together so as to move axially relative to one another to adjust a length of the spacer, wherein the first rod and the second rod have complementary screw threads adapted to expand the length of the spacer against tension of the at least one display panel and to retain the spacer in the expanded length against the tension of the at least one display panel,

wherein, in the expanded configuration, the spacer engages the first and second end members and holds the first and second end members spaced apart such that the at least one display panel is held drum-tight taut between the first and second end members, and, at least part of the spacer is located within an enclosure at least partly defined by the first end member, the second end member and the at least one taut display panel.

2. The assembly as claimed in claim 1, wherein, in the expanded configuration, the tautness of the at least one display panel is such to prevent substantial movement of the first end member relative to the second end member.

3. The assembly as claimed in claim 1, wherein the spacer is adjustable in length.

4. The assembly as claimed in claim 1, wherein the spacer is a telescopic rod.

5. The assembly as claimed in claim 1, wherein the assembly is adapted to be mounted to a seat stem of a bicycle frame.

6. The assembly as claimed in claim 1, wherein the first and second end members are substantially disc shaped.

7. The assembly as claimed in claim 6, wherein, in the expanded position, the assembly is substantially cylindrical.

8. The assembly as claimed in claim 1, wherein the first and/or second end member includes an aperture for receiving the spacer therethrough such that at least part thereof can be positioned to extend between the first and second end members.

9. The assembly as claimed in claim 1, wherein the at least one display panel is at least one fabric sheet.

10. The assembly as claimed in claim 1, wherein, in the collapsed configuration, the at least one display panel is not taut.

11. The assembly as claimed in claim 1, further including a light source within the enclosure to transilluminate the at least one display panel.

12. The assembly as claimed in claim 1, wherein the at least one display panel is substantially tubular.

13. An advertising assembly movable between an expanded configuration and a collapsed configuration, the assembly including:

a first end member;

a second end member;

at least one display panel attached to and extending between the first end member and the second end member; and

a spacer positionable such that at least part thereof extends between opposing sides of the first and second end members to maintain the assembly in the expanded configuration, the first and second end members being configured to receive or engage the spacer centrally, the spacer including a first rod and a second rod joined together so as to move axially relative to one another to adjust a length of the spacer, wherein the first rod and the second rod have complementary screw threads adapted to expand the length of the spacer against tension of the at least one display panel and to retain the spacer in the expanded length against the tension of the at least one display panel,

wherein, in the expanded configuration, the spacer engages the first and second end members and holds the first and second end members spaced apart such that the at least one display panel is held drum-tight taut between the first and second end members, and

wherein, in the expanded configuration, the first end member, the second end member and the at least one taut display panel at least partly define the boundaries of an internal space, and at least part of the spacer is positioned within the internal space.

14. An advertising assembly movable between an expanded configuration and a collapsed configuration, the assembly including:

a first end member;

a second end member;

at least one display panel releasably attachable to the first and second end members; and

a spacer positionable such that at least part thereof extends between opposing sides of the first and second end members to maintain the assembly in the expanded configuration, the first and second end members being configured to receive or engage the space centrally, the spacer including a first rod and a second rod joined together so as to move axially relative to one another to adjust a length of the spacer, wherein the first rod and the second rod have complementary screw threads adapted to expand the length of the spacer against tension of the at least one display panel and to retain the spacer in the expanded length against the tension of the at least one display panel,

wherein, in the expanded configuration, the at least one display panel is attached to the first and second end members and the spacer engages the first and second end members and holds the first and second end members spaced apart such that is held drum-tight taut between the first and second end members, and

wherein, in the expanded configuration, the first end member, the second end member and the at least one taut display panel at least partly define the boundaries of an internal space, and at least part of the spacer is positioned within the internal space.

15. An advertising assembly movable between a deployed configuration and a collapsed configuration, the assembly including:

a first end member;

a second end member;

at least one display panel attached to and extending between an outer perimeter of the first end member and an outer perimeter of the second end member; and

at least one removable spacer positionable such that at least part thereof extends between the first end member and the second end member to place the assembly in the deployed configuration, the end members being configured to receive or engage the at least one spacer at one or more positions such that, in the deployed configuration, the at least one display panel is held drum-tight taut between the first and second end members and the tautness is such to prevent substantial movement of the first end member relative to the second end member, the spacer including a first rod and a second rod joined together so as to move axially relative to one another to adjust a length of the spacer, wherein the first rod and the second rod have complementary screw threads adapted to expand the length of the spacer against tension of the at least one display panel and to retain the spacer in the expanded length against the tension of the at least one display panel,

wherein, in the deployed configuration, the at least one removable spacer is located within an enclosure at least party defined by the first end member, the second end member, and the at least one display panel.

16. The assembly as claimed in claim 15, wherein in the collapsed configuration, the first and second end members form a container and, in the expanded configuration, the assembly provides a shelf at least partly formed by the first end member, the second end member and the at least one display panel.
