Abstract
A sealing curtain assembly for door or window openings having a pair of tracks attached to frame members which are fixed to a base, a curtain having edges slidably engaging the tracks and being reversibly insertable into covers over each track, and hinges on each cover, whereby the hinges facilitate the lowering and raising of the curtain. Each track has a raised lip over which the curtain slides as the curtain moves up or down, the lip maintaining a seal against air flow, even when the curtain is distended upon the application of pressure. The bottom of the curtain has a weighted member and the base has spring clamps. As the curtain is lowered the weighted member engages the spring clamps causing the covers to press against the tracks, thereby providing a tight seal against airflow.
Description
- 1. Field of the Invention
- The field of the present invention relates to flexible enclosures for openings, such as doors and windows and, more particularly, to a curtain that can be raised and lowered with a motorized shaft to form a durable seal with the frame of an opening.
- 2. Technical Background
- The use of sealing curtains is known in the prior art. Generally, a sealing curtain apparatus comprises a curtain and tracks along the frame of an opening such as a door or window. The edges of the curtain are engaged by the tracks. As the curtain is moved towards a position covering the opening, the edges of the curtain travel along the tracks. The benefit of this design is that the sealed curtain prevents matter such as insects and debris from passing through the space between the curtain and the frame. However, the more tautly a sealed curtain is pulled across an opening, the more difficult it generally is to slide the curtain along the tracks.
- What is needed is a sealing curtain which provides a tight seal between the edges of the curtain and the frame of an opening, but which is easy to raise or lower along the opening.
- The sealing curtain assembly of the present invention has a pair of tracks attached to frame members of an opening such as a door or window where the frame members are secured to a base. The curtain assembly has a curtain having edges slidably engaging the tracks and being reversibly insertable into covers over each track. The covers are hinged to the tracks which allow the curtain to easily slide up and down along the opening. Each track has a raised lip over which the curtain slides as the curtain moves up or down, the lip maintaining a seal against air flow when the curtain is lowered over the opening. The bottom of the curtain has a weighted member and the base has spring clamps. As the curtain is lowered the weighted member engages the spring clamps causing the covers to press against the tracks, thereby providing a tight seal against airflow, even when the curtain is distended upon application of pressure. The curtain assembly also has a rotatable shaft and motor assembly which will raise the curtain to uncover the opening or lower the curtain to close the opening.
- An advantage of the curtain assembly of the present invention is a flexible curtain that covers the opening of a window or garage which is durable and seals the opening from air flow.
- Another advantage is a pair of covers which seal the edges of the curtain along the tracks, wherein the covers rotate away from the tracks to facilitate the raising and lowering of the curtain.
- Another advantage is a pair of spring clamps which bias the covers towards the tracks to maintain the curtain taut and sealed when the curtain is in a lowered position.
- Another advantage is a curtain which can be raised and lowered with a motor to cover and uncover the opening.

FIG. 1 shows thecurtain assembly 10 of the present invention.First frame member 12 andsecond frame member 14 define an opening 15 of a door or window.Frame members base 35. Afirst track 11 is attached tofirst frame member 12 and asecond track 13 is attached tosecond frame member 14. Arotatable shaft 17 is positioned at the top ends offrame members brackets 18. Amotor 19 may be attached to one of the brackets, such asbracket 18 to rotateshaft 17. Aflexible curtain 20 is attached toshaft 17 and can be rotated onshaft 17 bymotor 19 to wind or unwindcurtain 20 on toshaft 17. Curtain 20 has a bottom or leadingedge 21. The outer edges oftracks hinge elements 22. The outer edges ofcovers 23 havehinge elements 24. Thehinge elements tracks edge 21 ofcurtain 20 has a weightedmember 25 which is retained within holders orspring clamps 26 attached at the bottom ofbase 35. Thespring clamps 26 are flared or form a cam at their openings to guide theweighted member 25 into the interior of thespring clamps 26. The spring clamps 26 press against the weightedmember 25 which biases covers 23 againsttracks -
Tracks inner lips 27 along whichcurtain 20 slides as it is raised and lowered by the action ofmotor 19 andshaft 17. Thelateral edges 31 ofcurtain 20 fit overlips 27 and are inserted intocovers 23. -
FIG. 2 shows thecover 23 andtrack 13 disassembled.Cover 23 has anouter tab 28 and aninner tab 29. There are a plurality ofholes 40 intrack 11 andtrack 13 to attach them to framemembers pin 32 is used to connectcover 23 tosecond track 13. -
FIG. 3 illustrates thelateral edge 31 ofcurtain 20.Lateral edge 31 has a semi-rigid outer flap for insertion intoinner tab 29.Lateral edge 31 is inserted intoouter tab 28. -
FIG. 4 illustrates the assembly of thesecond track 13 tosecond frame member 14, of thecover 23 tosecond frame member 14, and oflateral edge 31 ofcurtain 20 intocover 23. Thehinge elements 24 ofcover 23 engage thehinge elements 22 ofsecond track 13, and are locked into place byhinge pin 32.Cover 23 is, thus, hinged rotatably tosecond track 13. This hinge assembly 16 facilitates the raising and lowering ofcurtain 20 alongtracks First track 11 is assembled in an identical fashion assecond track 13. The curtainlateral edge 31 passes overinner lip 27 and is inserted intoouter tab 28 and theouter flap 30 ofcurtain 20 is inserted intoinner tab 29. The oppositelateral edge 31 is inserted intocover 23 onfirst track 11 in a similar fashion. As covers 23 press the lateral edges 31 towards their respective tracks by action of the spring clamps 26 onweighted member 25,curtain 20 is pulled taut over theinner lips 27 oftracks opening 15. If force is applied againstcurtain 20, cover 23 will remain pressed againsttracks curtain 20 still maintaining its seal alonginner lips 27. -
FIG. 5 shows a cross-section ofcurtain 20.FIG. 6 shows a cross-section of theopening 15 formed byframe members tracks members bolts 41. The arrows show the direction of rotation ofcovers 23 as they are pulled away fromtracks curtain 20.FIG. 7 shows a cross-sectional view of the curtain secured in the tracks with the covers in a closed position. - The foregoing description has been limited to specific embodiments of this invention. It will be apparent, however, that variations and modifications may be made by those skilled in the art to the disclosed embodiments of the invention, with the attainment of some of all of its advantages and without departing from the spirit and scope of the present invention. For example, the scaling curtain assembly can be constructed to cover any type of opening. The curtain can be made of any flexible type of cloth, plastic, and the like. The motor may be operated remotely to raise and lower the curtain. The tracks and covers can be constructed to operate with curtains of any desired thickness.
- It will be understood that various changes in the details, materials, and arrangements of the parts which have been described and illustrated above in order to explain the nature of this invention may be made by those skilled in the art without departing from the principle and scope of the invention as recited in the following claims.
