GARNET T ABRAHAM ATTORNEY PATENTEU JULZU IBTI SHEET 6 DF 5 ATTORNEY DRAW CURTAIN APPARATUS V This invention relates to an improved draw shade or blind apparatus which permits adjustment of both the level of the shade or blind and its length.

In conventional draw shades and blinds the fabric body or ladder is generally secured at the top'of a window opening so that the control cords of the shade or blind which are connected to the bottom edge thereof permit only the bottom edge to be raised or lowered over the window to any desired height. These conventional shades or blinds, however, suffer from the disadvantage that when opened from the bottom, they expose the privacy of the occupants of the room. .It is therefore desirable to provide a shade or blind which may also be opened from the top of a window while covering the bottom half of the window to maintain the privacy of the occupants of the room.

Accordingly, the present invention provides a shade -.or blind apparatus wherein the shade or blind may be lowered from both the top and the bottom ofa window by utilizing the same control cords. The shade or blind is not secured to the top of the window frame but fastened to a movable cross member which may be raised or lowered away from the topof the window. The bottom edge of the shade or blind bodyalso contains a second crossmember so that its level may also be adjusted independently from the first crossmember. This provides the shade or blind of the invention with two modes of adjustment so that the portion of shade or blind deployed over the window as well as its level may be adjusted independently.

It is therefore an object according to the present invention to provide a shade or blind apparatus which is adjustable from both its top and bottom portions using the sameeontrol cords.

It is still a further object according to the present invention to provide a shade or blind apparatus which is simple in design, easy to manufacture, and reliable in operation.

Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings which disclose one embodiment of the present invention.

12 and 13. A more detailed explanation of the window covering apparatus follows with respect to FIGS. 9-12.

Referring to FIGS. 912, there is shown another embodiment of the apparatus according to the invention consisting of a main horizontal support 30 which is retained against a wall structure by means of supporting bracket 31 bolted on each end of support 30. Screws 22 are used to mount bracket 31 to the wall structure. In one embodiment, adjacent to each end of horizontal support 30 is located a threaded stud 33 disposed vertically through support 30, and retained in the support by means of wingnut 32 and threaded flange 34. Stud 33 is adjusted so that its foot 35 will serve as a stop in preventing a first crossmember 19 from being elevated above the level of foot 35. Between'the second or bottom crossmember 16 and the upper or first crossmember 19 is, in one embodiment, supported a curtain body 115. Control cords are collected at .one end of the curtain apparatus and passed through element 'one or more additional control cords may be used, such as control cord 105. Control cord is secured to bottom crossmember 16 at knot 70, and passes through eyelets 75, around pulleys 76 and 71, and through an additional outer 'pulley (not shown) adjacent to either pulleys 40 or 43, and

then descends through element 65 and around an additional outer pulley (not shown) in handle 17. Cord 105 would then terminate in element 65 and be secured adjacent to knots 101a or 1040, or be held'by screw 166 or element 165. Control cords 10l-l04 are collected through a

multipulley wheel

40, 41, 42 and-43 which is pivoted around axis 44 and mounted within housing 36.

Center pulley segments

41 and 42 consist of two drums for receiving

control cords

101 and 104 while end pulleysegments 40 and 43 receive control cords I02 and 103, respectively.

Control cords

102 and 103 will operate independently in raising and lowering bottom crossmember 16 when

cords

101 and 104 become stationary. Openings are provided in housing 36 at the front and bottom in order to guide cords 100. Also pivotablly retained in housing 36 on axis 38 is alatch 37 which includes a saw tooth engaging edge 39 for engagement with cords 10Il04. At the other end of horizontal support 30, pivoted on axis 52 are dual pulleys 50 and 51 for collecting

cords

101 and 102, respectively. In'one embodiment,

cords

101 and 102 cross over during their travel across support 30 as shown in detail in FIG. 10. As an alternative to utilizing foot 35 of stud 33 in order to limit the height of travel of support 19,

cords

104 and 101 may include a knotted portion 104a, as shown in detail in FIG. 11, and 101a (now shown) which are larger in diameter than the openings at the bottom of housing 36 which permit

cords

103 and 104 to travel to pulley 43 and 41, respectively.

Referring to FIG. 12, there is shown a detailed cross-sec tional view of the control cords 100 including sliding elements 65 through which cords 101-104 pass therethrough. The bot.- tom portion of element 65 includes an opening 66 wherein

cords

101 and 104 include knotted portions 101a and 1040 tightly secured within opening 66. Handle 17 includes

dual pulley

60 and 61 which are pivotably mounted on axis 62 secured at the open end of handle 17.

Cords

101 and 103 are actually the same cords which converge on pulley 61, while

cords

102 and 104 are the same cord verging on pulley 60.

FIG. 13 discloses another possible embodiment for element 65 shown as element 165 in which a screw 166 threadably engages through element 165 so that its end will secure

cords

101 and 104 within the element. Screw 166 is designed to replace knotted portions 101a and 104a of the design of FIG. l2v

The operation of the apparatus is described with respect to FIGS. 14, 15 and 16. In FIG. 14, shade body 115 is shown lowered away from support 30 by first disengaging latch 37 and lifting up on handle 17. In FIG. 15, shade body 115 is shown covering the entire window opening by pulling downward on handle 17 so that upper crossmember 19 contacts foot stops 35 on shaft 33. The user can then lock the cord by engaging cord latch 37. In FIG. 16, while the user continues to pull handle 17, lower crossmember 16 will continue to rise lifting the remaining portion of shade body on 115 to its uppermost position. Latch 37 can then he used to lock cords 100 in place.

In its position as shown in FIG. 16, the user can grip element 65 in place and raise handle 17 and allow the weight of the shade (or blinds) to draw

cords

102 and 103 through dual handle pulleys 60 and 61, through the holes of element 65, around outer pulley segments 40 and 43 to lower the bottom rail of crossmember 16 in order to close the window opening. Top crossmember 19 remains in place while the user holds element 65.

When the shade body is lowered as in FIG. M, the user may grip handle 17 and arrest cords 100 in the handle pulley, and by pulling downward on the combination, both crossmembers will move upward simultaneously to cover over the window.

Referring to FIG. 17 and 18, there is shown another embodiment of the shade apparatus according to the invention utilizing shade body 215 which is raised and lowered by means of

control cords

102 and 103 which are wrapped around the bottom rolled end of the shade body and secured to first crossmetnber 19 at tie point 20. The top portion of shade body 215 is secured to first crossmember 19 which is raised and lowered by m.- ns of

cords

101 and 104 connected to eyelets 80, as described with respect to the previous embodiment. The lower crossmember 16 in this embodiment consists of the center of the rolled fabric 215 so that the movement of handle 17 and element 65 will raise and lower the level of upper support 19 as well as the length of shade body 215.

Referring to FIGS. 19-22, there is shown a further embodiment of the invention capable of utilizing venetian blinds in place of a shade body between the first and second crossmember. In FIGS. 1922, there is shown one of the control cords 101 terminating at its end in eyelets 125 for supporting a horizontally extending rigid wire hanger 126 at wire indenta tion 129. Each end of hanger wire 126 includes a loop 129 which engages edges 127 on the ends of crossmember 119. Loop 129 will receive eyelet 125 when first crossmember 119 is completely tilted so as to close slats 131 as shown in FIG. 21. First crossmember 119 has rolled edges 127 which hold support ladder 130 at a point where it is substantially in line with the center of gravity of cord 101 so as to assume maximum stress in order to completely close slats 131 as shown in FIG. 21. As shown in detail in FIG. 20, a long slot 132 is formed in crossmember 119 so that sluts 131 may be tilted or closed by moving eyelet along wire 126 in order to engage indentations 128 or loops 129 without obstructing the move' ment of control cords 102, as shown in FIG. 21. In this manner, the position of slats 131 may be easily tilted or opened by hand to any desired position without the use of additional control cords or cables.
