Abstract
A retractable display apparatus (10) comprises a housing (12), a drum (14) journalled for rotation in the housing, a display sheet (16) wound on to the drum, and a slot (22) in the housing through which the display sheet can be unwound from the drum against the action of a return spring, wherein a flexible leader strip (28) extendable through the slot is provided for releasably attaching the display sheet to the drum (14) in an easy and convenient manner outside the housing (12). The leader strip (28) has ribs (28.2) along both longitudinal edges, one rib being engageable with the drum and the other with an undercut formation (30) secured to the display sheet (16).
Claims17
A retractable display apparatus comprising a housing, a drum journalled for rotation in the housing, a display sheet wound on to the drum, and a slot in the housing through which the display sheet can be unwound from the drum against the action of a return spring, wherein
- a leader strip includes first and second edges and is attached to the drum along the first edge, the leader strip being dimensioned to extend through the slot when the drum is unwound sufficiently;
- a first securing formation is provided on the leader strip spaced from the first edge, the first securing formation being dimensioned to pass through the slot;
- and
- a second securing formation is attached to the display sheet, the first and second securing formations being releasably engageable with each other.
A method of attaching a display sheet to a retractable display apparatus comprising a housing, a drum journalled for rotation in the housing on which the display sheet is to be wound, and a slot in the housing through which the display sheet can be unwound from the drum against the action of a return spring, including the steps of:
- a) securing one edge of a leader strip to the drum, the leader strip being dimensioned to extend through the slot when the drum is unwound sufficiently and having a first securing formation substantially at its opposed edge;
- b) attaching the display sheet to a second securing formation;
- and
- c) engaging the first and second securing formations with each other when the first securing formation is outside the housing.
A retractable display apparatus for use with a display sheet, comprising:
- a) a housing defining a slot;
- b) a drum journalled for rotation in the housing;
- c) a leader strip having first and second opposed edges, and attached to the drum along said first edge, the leader strip being dimensioned to extend through the slot when the drum is sufficiently unwound;
- d) a first securing formation provided on the leader strip at the second edge, the first securing formation being dimensioned to pass through the slot;
- and
- e) a second securing formation for attachment to the display sheet.
