Signal device

Claim 2

A foldable signal device comprising in combination: an elongated flat base member having curved downturned end portions adapted to engage a supporting surface; a second flat base member centrally mounted on a frictional pivot axis on the under side of said first base member and having its ends pivotable from a position frictionally engaging said downturned end portion to a spread position; a first essentially flat double-sided reflective signal member attached to said base member with the reflective surfaces thereof substantially perpendicular thereto; stop means between said base members to hold the respective ends in said frictional engagement; a pair of essentially flat double-sided reflective signal members pivotally attached at one of their ends on opposite sides of and at the ends of said first signal member; said signal members being of substantially the same length and longer than one-half the length of said first signal member and pivotable from said base member To form an apex above said base member; snap fastener means to hold said signal arms in said apex position; and snap fastener means to hold said signal arms in the folded position contiguous to the sides of said first signal member.

Claim 3

A signal device in accordance with claim 1 in which: a. an end of said second base member is rounded to provide a cam surface frictionally engaging the under surface of an end of said flat base member.

Claim 4

A signal device in accordance with claim 2 in which: a. the pivotal attachment of said signal members to said first signal members to said first signal member comprises a rivet member extending through said members; b. the means for attachment of said signal arms in said apex position comprises a rivet member extending through the pivotal ends of each of said signal members and having mating snap fastener heads on the inside; and c. one of said rivet members at said apex position also being engageable with one of said rivets pivotally holding the opposite signal arm.

Claim 5

A foldable signal device comprising, in combination: a first base member having a flat upper surface and curved downturned end portions the edges of which are adapted to engage a horizontal supporting surface; a second flat base member pivotally mounted on a frictional axis to the under side of said first base member and having its ends pivotable from a position of registry between the downturned ends of said first base member with the under side of said second base member in the plane of the edges of said downturned end portions; a first signal member having a reflective surface on each side and being attached to said first base member in a plane perpendicular to said flat surface of said first base member; a pair of signal arms having reflective surfaces on each of their respective sides; said signal arms each being substantially the same length as said first signal member and having one of their ends pivotally attached by rivet means on opposite sides and at the respective ends of said first signal member whereby said signal arms are foldable to a closed position with their respective inner reflective surfaces contiguous to and on opposite sides of said first signal member and edgewise upon said upper surface of said first base member and pivotable away from same to form an apex at their other ends with said signal members in a triangular configuration; and snap fastener means at the ends of said signal arms to interengage and hold said signal arms at the apex, said snap fastener means being adapted to interengage with said rivets to hold said signal arms in the folded position.

Claim 6

A foldable signal device comprising, in combination: a first base member having a flat upper surface and curved downturned end portions the edges of which are adapted to engage a horizontal supporting surface; a second flat base member pivotally mounted on a frictional axis to the under side of said first base member and having its ends pivotable from a position of registry between the downturned ends of said first base member with the under side of said second base member in the plane of the edges of said downturned end portions; a first signal member having a reflective surface on each side and being attached to said first base member in a plane perpendicular to said flat surface of said first base member; a pair of signal arms having reflective surfaces on each of their respective sides; said signal arms each being substantially the same length as said first signal member and having one of their ends pivotally attached by rivet means on opposite sides and at the respective ends of said first signal member whereby said signal arms are foldable to a closed position with their respective inner reflective surfaces contiguous to and on opposite sides of said first signal member and edgewise upon said upper surface of said first base member and pivotable away from same to form an apex at their other ends with said signal members in a triangular configuration; and snap fastener means at the ends of said signal arms to interengage and hold said signal arms at the apex, said snap fastener means being adapted to interengage with said rivets to hold said signal arms in the folded position.

Claim 7

A foldable signal device in accordance with claim 4 in which: said signal member and signal arms each include an elongated flat backing member having opposed outwardly directed edge flanges; and the respective reflective surfaces comprise a panel of reflective material having coplanar edges along their sides engaged under said edge flanges of said backing member.

Claim 8

A foldable signal device in accordance with claim 4 in which: an end of said second base member is rounded to frictionally cam against the curved undersides of the downturned ends of said flat base member in the position of registry.

Claim 9

A foldable signal device in accordance with claim 4 in which: an upright flag staff support member is provided intermediate the ends of said first base member and spaced from said first signal member a distance sufficient to yieldably receive the signal arm pivoted on that side of said first signal member; and a flag and staff are provided to removably interengage with said support with said flag at a position toward said apex.

Claim 10

A foldable signal device in accordance with claim 7 in which: said flag staff includes a tubular member and a rodlike member received therein in telescoping relationship; an elongated slot in the wall of said tubular member, said slot having an offset notch in One edge; a protuberance on said flag staff adapted to engage in said slot as the staff telescopes within said tubular member, and also adapted to engage in said notch upon rotation of said flag staff in relation to said tubular member, whereby said flag staff and tubular member telescope to a compact length and are extendable with said flag at signal position with said protuberance engaging said notch.
