Abstract

The present invention is directed to a roll-up wall. The roll-up wall and its components may be used to divide existing larger spaces into smaller spaces with a sound-attenuating barrier. In this invention a sound-attenuating panel is attached to a roller drum which, when turned on its axis by a winding mechanism, deploys or retracts the sound-attenuating panel. This invention discloses details of the sound-attenuating panel, the roller drum, a sound-attenuating guide system, a lower sound-attenuating seal, and an interlocking system. More particularly, this invention discloses an interlocking system which removably attaches a sound-attenuating panel to a roller drum. This invention discloses a plurality of embodiments of the interlocking system and provides detailed descriptions of each embodiment.

First claim

We claim:

1. A roll-up wall comprising:
a sound-attenuating panel having an upper side, a lower side, a first vertical side, and a second vertical side;
a clam-shell roller drum comprising two half pipes joined by spaced apart hinges along two longitudinal sides and spaced apart tabs and notches along a first opposed longitudinal side to accept an interlocking system of the sound-attenuating panel, the clam-shell roller drum further comprising latches adjacent the respective ends of the first opposed longitudinal side and a second opposed longitudinal side to clamp the adjoining opposed longitudinal sides together;
a winding mechanism comprising a power cord disposed inside and attached to the clam-shell roller drum;
a first mounting bracket and a second mounting bracket;
the first mounting bracket coupled to and supporting one end of the clam-shell roller drum and the second mounting bracket coupled to and supporting the opposite end of the clam-shell roller drum;
a first flexible, sound-attenuating guide and a second flexible, sound attenuating guide;
the first flexible, sound-attenuating guide joined to the first vertical side and the second flexible, sound-attenuating guide joined to the second vertical side;
a first guide receiver channel and a second guide receiver channel;
the first guide receiver channel vertically attached to a first vertical side of a structure opening and the second guide receiver channel vertically attached to an opposing second side of the structure opening;
the first sound-attenuating guide disposed within the first guide receiver channel and the second sound-attenuating guide disposed within the second guide receiver channel;
a flexible, sound-attenuating seal joined to the sound-attenuating panel along the lower side of the panel;
the interlocking system comprising a plurality of coupling elements intermittently spaced longitudinally along the upper end of the sound-attenuating panel comprising grommets with a hole perforating the sound-attenuating panel in the center of each grommet commensurate with the spaced apart tabs and notches of the first opposed longitudinal side of the clam-shell roller drum, the coupling elements being inserted onto the respective tabs and notches, attaching the sound-attenuating panel to the clam-shell roller drum, the tabs comprising a notched upper edge coupling to the second opposed longitudinal side of the clam-shell roller drum such that the notch allows the respective opposed longitudinal sides to form a planar connection when the roller drum is closed.

2. The roll-up wall of claim 1 , wherein the sound-attenuating panel comprises mass loaded vinyl.

3. The roll-up wall of claim 1 , wherein the clam-shell roller drum comprises metal which is selected from the group consisting of steel, stainless steel, aluminum, brass, and titanium.

4. The roll-up wall of claim 1 , wherein the clam-shell roller drum comprises material which is selected from the group consisting of polyvinyl chloride, carbon fiber, wood, engineered wood, nylon, and plastic.

5. The roll-up wall of claim 1 , wherein the winding mechanism disposed inside and attached to the clam-shell roller drum rotates the clam-shell roller drum on its longitudinal axis to raise or lower the sound-attenuating panel.

6. The roll-up wall of claim 1 , wherein the mounting brackets comprise metal selected from the group consisting of steel, stainless steel, aluminum, brass, and titanium.

7. The roll-up wall of claim 1 , wherein the mounting brackets comprise material selected from the group consisting of polyvinyl chloride, carbon fiber, nylon, polyoxymethylene, and plastic.

8. The roll-up wall of claim 1 , wherein the first and second flexible, sound-attenuating guides each comprise a strip of mass-loaded vinyl rolled longitudinally and joined to itself to form a bead using chemical or mechanical attachment, or combinations thereof.

9. The roll-up wall of claim 1 , wherein the flexible, sound-attenuating guides are joined to the sound-attenuating panel using chemical or mechanical attachments, or combinations thereof.

10. The roll-up wall of claim 1 , wherein the first and second guide receiver channels each comprise an inner surface and an outer surface.

11. The roll-up wall of claim 1 , wherein the first and second guide receiver channels each comprise metals selected from the group consisting of steel, stainless steel, aluminum, brass, titanium, and alloys.

12. The roll-up wall of claim 1 , wherein the first and second guide receiver channels each comprise materials selected from the group consisting of polyvinyl chloride, nylon, polyoxymethylene, and plastic.

13. The roll-up wall of claim 1 , wherein the first and second guide receiver channels are affixed vertically to the structures by chemical or mechanical attachments, or combinations thereof.

14. The roll-up wall of claim 1 , wherein the first and second guide receiver channels comprise a friction resistant material disposed on an inner surface of the channels.

15. The roll-up wall of claim 14 , wherein the friction resistant material disposed on the inner surfaces of the guide receiver channels is selected from the group consisting of nylon, ultra-high molecular weight polyethylene, titanium nitride, chromium nitride, and polytetrafluoroethylene.

16. The roll-up wall of claim 1 , wherein the sound-attenuating seal comprises a strip of mass-loaded vinyl rolled longitudinally and joined to itself to form a bead using chemical or mechanical attachments, or combinations thereof.

17. The roll-up wall of claim 1 , wherein the sound-attenuating seal is joined to the lower side of the sound-attenuating panel using chemical or mechanical attachments, or combinations thereof.

18. The roll-up wall of claim 1 , wherein the sound-attenuating seal creates a substantially sound-attenuating barrier between the sound-attenuating panel and a floor when the panel is fully deployed.

19. The roll-up wall of claim 1 , wherein the first and second longitudinal sides of the clam-shell roller drum comprise case latches adjacent the respective ends of the roller drum.

20. The roll-up wall of claim 1 , wherein the interlocking system comprises 14 tabs and notches along the first opposed longitudinal side of the clam-shell roller drum.
