Abstract
An information presentation device and methods for mounting a display sheet to the device. The device includes an elongate housing having a first opening through which the display sheet passes. The display sheet is wound onto a drum within the housing. A releasable attachment arrangement in the form of an attachment strip to which a display sheet can be affixed and a receiving slot in the drum permits a display sheet to be attached to and removed from the information presentation device without the need to disassemble the device.
Claims10
An information presentation device for erecting a display sheet from a housing comprising:
- an elongate housing having two opposed end walls and a first opening extending longitudinally between said end walls;
- a drum having an outer surface, said drum extending about a longitudinal axis and mounted in supports at said end walls for rotation in said housing between said end walls such that said longitudinal axis is substantially parallel to said first opening in said housing;
- and
- attachment means for attaching said display sheet to said drum such that said display sheet can be wound around said drum, said attachment means comprising:
- an attachment strip for attachment to one end of said display sheet, and
- receiving means on said drum for releasably engaging said attachment strip;
- said attachment strip and said receiving means forming a releasable mechanical connection;
- said drum is provided with a biasing spring such that when said display sheet is attached to said drum, said display sheet can be drawn into said housing under an action of the biasing spring;
- wherein said attachment means is configured such
- that said releasable mechanical connection forms abutment surfaces between the attachment strip and the drum forming a positive stop, said mechanical connection being releasable while said drum remains mounted in supports for rotation between said end walls within said elongate housing.

A method of mounting a display sheet to an information presentation device, said device comprising:
- an elongate housing having two opposed end walls and a first opening extending longitudinally between said end walls;
- a spring-biased drum extending about a longitudinal axis and mounted for rotation in said housing between said end walls such that said longitudinal axis is substantially parallel to said first opening in said housing;
- attachment means for attaching a display sheet to said drum such that said display sheet can be wound around said drum, said attachment means comprising:
- an attachment strip attached to one end of said display sheet, and
- receiving means on said drum for releasably engaging said attachment strip, said attachment strip and said receiving means forming a releasable mechanical connection, said releasable mechanical connection forming abutment surfaces between said attachment strip and said drum forming a positive stop;
- said method comprising the steps of:
- bringing said receiving means on said drum into alignment with said first opening in said elongate housing;
- inserting said attachment strip through said elongate opening in a direction substantially perpendicular to said longitudinal axis such that said attachment strip is brought into engagement with said receiving means on said drum while said drum remains mounted for rotation between said end walls;
- winding said display sheet around said drum;
- and
- tensioning said spring-biased drum such that said drum tends to retain said display sheet in said housing.

A method of mounting a display sheet to an information presentation device, said device comprising:
- an elongate housing having two opposed end walls and a first opening extending longitudinally between said end walls;
- a pretensioned spring-biased drum extending about a longitudinal axis and mounted for rotation in said housing between said end walls such that said longitudinal axis is substantially parallel to said first opening in said housing;
- attachment means for attacking a display sheet to said drum such that said display sheet can be wound around said drum, said attachment means comprising:
- an attachment strip attached to one end of said display sheet, and
- receiving means on said drum for releasably engaging said attachment strip
- said attachment strip and said receiving means forming a releasable mechanical connection, said releasable mechanical connection forms
- abutment surfaces between the attachment strip and the drum forming a positive stop;
- and
- locking means for locking said pretensioned spring-biased drum such that said receiving means on said drum is aligned with said first opening in said housing;
- said method comprising the steps of:
- inserting said attachment strip through said first opening in a direction substantially perpendicular to said longitudinal axis such that said attachment strip is brought into engagement with said receiving means on said drum while said drum remains mounted for rotation between said end walls;
- and
- releasing said locking means such that said display sheet is caused to be wound around said drum.
