Abstract
An erectable sleeve is movable between a relatively flat collapsed orientation and a relatively high rectangular erected orientation for use. The sleeve comprises a bottom member and a pair of end members, each end member being pivotally secured to a respective end of the bottom member and pivotable between a folded position wherein the end member is substantially parallel to the bottom member and an extended position wherein the end member is extended substantially perpendicular to the bottom member. A detachable top member includes friction fit means for engagingly receiving the free ends of the end members for maintaining the end members in their extended position.
Claims18
An erectable sleeve for receiving, to project therethrough, a unit of generally rectangular cross section comprising:
- (A) a bottom member having a generally flat web section;
- (B) a pair of end members, each end member having a generally flat web section and one end thereof pivotally secured to a respective end of said bottom member and being pivotable between a folded position wherein said end member web section extends generally parallel to and overlies said bottom member web section and an extended position wherein said end member web section extends generally perpendicularly to said bottom member web section;
- and
- (C) a detachable top member having a generally flat web section and means adapted to engagingly receive the free ends of said end members for maintaining said end members in their extended position.
An erectable sleeve for receiving, to project therethrough, a unit of generally rectangular cross section comprising:
- (A) a bottom member having a generally flat web section;
- (B) a pair of end members, each of said end members having inwardly turned side flanges, a generally flat web section and one end thereof pivotally secured to a respective end of said bottom member and being pivotable between a folded position wherein said end member section extends generally parallel to said bottom member web section and an extended position wherein said end member web section extends generally perpendicularly to said bottom member web section;
- and
- (C) a detachable top member having a generally flat web section and means adapted to engagingly receive the free ends of said end members for maintaining said end members in their extended position, said top member maintaining means comprising downwardly turned side flanges, downwardly turned end flanges, and a pair of downwardly extending locking flanges secured to said top member web section, each locking flange extending closely parallel to a respective one of said top member end flanges to define a first gap for substantially the entire length thereof but terminating short of said top member side flanges to define second gaps, said top member being adapted to maintain said end members in their extended position by receiving portions of said end member side flanges in said second gaps intermediate said top member locking flanges and said top member side flanges and by receiving portions of said end member web sections in said first gaps intermediate said locking flanges and said top member end flanges.
A method of erecting a sleeve for receiving a unit of generally rectangular cross-section comprising the steps of:
- (A) providing a bottom member having a generally flat web section;
- a pair of end members, each end member having a generally flat web section and inwardly turned flanges, each end member having one end thereof pivotally secured to respective end of said bottom member and pivotable between a folded position wherein said end member web section extends generally parallel to said bottom member web section and an extended position wherein said end member web section extends generally perpendicular to said bottom member web section;
- and a detachable top member having a generally flat web section, downwardly turned side flanges, downwardly turned end flanges, and a pair of downwardly extending locking flanges secured to said top member web section, each locking flange extending closely parallel to a respective one of said top member end flanges for substantially the entire length thereof but terminating short of said top member side flanges;
- (B) moving said end members to said extended position;
- and
- (C) positioning said top member atop the free ends of said end members to maintain said end members in said extended position with portions of said end member side flanges extending intermediate said top member locking flanges and said top member side flanges and portions of said end member web sections extending intermediate said locking flanges and said top member end flanges.
