Abstract

A dual extrusion hinged sign hanger hangs from the ceiling and holds signs, banners, posters, and any other sheet type of display material. Display material can be easily changed within a smooth non-damaging holder portion which opens for free non-friction insertion of the display material. The closure has flexible tabs on one side and a smooth flexible curved surface to hold the display material against the tabs. The closure acts perpendicularly to the display material with a snap together closure that does not come in contact with the display material.

Claims

1. A hanger device for sheet display material with non-damaging easy opening and closing capability, the hanger device comprising:

a first extrusion piece having a mounting means and having a downwardly facing space capable of receiving at least one piece of sheet material freely insertable therein, the space having a vertically oriented surface having at least one flexible tab protruding from the vertically oriented surface;

a second extrusion piece pivotally mounted to the first extrusion piece by a hinge means, the second extrusion piece having a smooth holder surface facing the at least one flexible tab, the holder surface capable of moving from a first position spaced apart from the flexible tab a sufficient distance to admit the sheet material with a non-contact insertion therebetween to a second position pressing against the at least one flexible tab to retain the at least one piece of sheet material sandwiched therebetween, the second extrusion piece further comprising a snap closure means for engaging the first extrusion piece, the snap closure means spaced apart from the holder surface, so that the second extrusion piece is capable of being pivoted toward the first extrusion piece to engage the snap closure means to maintain the holder piece in the second position to retain the sheet material and further capable of being pivoted away from the first extrusion piece to disengage the snap closure means and move the holder surface to the first position to release the sheet material.

2. The hanger device of claim 1 wherein the first extrusion piece comprises a downwardly oriented square U-shaped channel and the second extrusion comprises an upwardly oriented V-shaped channel attached to the first extrusion piece by a living hinge at an end of a first leg of the U-shaped channel attached to the interior point of the V of the V-shaped channel.

3. The hanger device of claim 2 wherein the at least one flexible tab protrudes inwardly from a second leg of the U-shaped channel and the smooth holder surface comprises a first leg of the V-shaped channel formed in a smooth curve and positioned within the U-shaped channel facing the at least one flexible tab.

4. The hanger device of claim 3 wherein the snap closure means comprises a flexible downwardly angled ridge facing outwardly on the first leg of the U-shaped channel of the first extrusion piece capable of receiving an upwardly angled ridge on a second leg of the V-shaped channel of the second extrusion piece positioned out side of the U-shaped channel with a snap fit therebetween.

5. The hanger device of claim 1 wherein the snap closure means comprises a flexible downwardly angled ridge of the first extrusion piece capable of receiving an upwardly angled ridge of the second extrusion piece with a snap fit therebetween.

6. The hanger device of claim 1 wherein the at least one flexible tab comprises two flexible tabs angled upwardly protruding from the vertically oriented surface along the length of the hanger device.

7. The hanger device of claim 6 herein the hanger surface comprises a smooth curved surface capable of contacting the flexible tabs along the length of the hanger device in the second position.

8. The hanger device of claim 1 wherein the mounting means comprises a means for receiving a hanger built into a top portion of the first extrusion piece.

9. The hanger device of claim 8 wherein the means for receiving a hanger comprises two angled tabs extending from the top portion of the first extrusion piece forming a T-shaped slot along the top portion of the first extrusion piece, the T-shaped slot capable of receiving T-shaped hangers insertable therein.

10. The hanger device of claim 1 wherein the first extrusion piece and the second extrusion piece are fabricateed of extruded plastic in a dual extrusion.
