So that the post pivot 54 engages with the stem connection opening 52.
[0044] As seen in Fig. 2, the louver panel 60 has support by the inside post 21 and the louver clip 30. The actuator bar 44 rotates the transmission axle 71 relative to and axle bushing 72.
[0045] The transmission axle 71 connects to a pair of actuator bars 44, a left actuator bar and a right actuator bar actuate a left row of louver clips and a right row of louver clips. Thus, the right row of louver clips and the left row of louver clips are mechanically connected through the transmission axle 71. The transmission axle 71 provides an even force output between the left and right sides. The transmission axle 71 works in any orientation so that the louver can be vertically mounted as a wall in addition to a roof.
[0046] The general configuration of the pergola is rectangular but can also be made in a variety of different shapes such as square or octagonal. The pivot link 53 is also formed in a pair of rows, namely a left row of pivot links and a right row of pivot links provide a left and right symmetrical force transmission. Similarly, the track 55 is also formed with a right track and the left track supporting the right and left rows of pivot links and louver clips. Columns 58 provide a vertical support for the pergola crossbeams 59. The crossbeams 59 can be integrally formed with the track 55, or can be made as separate members. Preferably, the crossbeams 59 are integrally formed with the track 55 and the groove on the track.
[0047] The louver panel 60 has a louver flat portion 61 that extends upwardly to a louver upper bend 62. The louver flat portion 61 also extends downwardly to a louver lower bend 63. The louver lower bend 63 has a louver lower hook 64 that terminates at a louver lower hook edge 66. Similarly, the louver upper bend 62 extends to a louver upper hook 65 with a louver upper hook edge 67. The louver panel 60 also includes a louver right edge 68 and a louver left edge 69. The louver upper hook edge 67 engages to the upper arm hook edge 36, and the louver lower hook edge 66 engages to the lower arm hook edge 35. Thus, the louver panel 60 snaps to the right louver clip and the left louver clip. The louver clips 30 are formed as springs for bias retention of the louver panels 60.
[0048] As seen in Fig. 3, the pergola louvers can be rotated to an open position. In open position, the louver clips 30 are mounted between and on the inside post 21 and the outside post 22 the louver clip lower arm 31, the louver clip lower arm hook 33, and the lower arm hook edge 35 can be extended downwardly when the pergola is in an open position. The clip flange mount 37 extends generally vertically after being pivoted on the post joint 39.
84728351.1
[0049] The link 41 connects to adjacent links and provides transmission of force equally to all of the stems 50 at the first link connection 42 and the second link connection opening 48. Each stem 50 extends upwardly from each stem base 51. Each stem connection opening 52 may communicate or cooperate with the stem slot 57 and provide a mounting to the pivot link 53. The track 55 extends horizontally to be supported by columns 58.
[0050] As seen in Fig. 4, a right or left row oflouver clips 30 are mounted on a track 55. A louver clip has a louver clip lower arm 31 and a louver clip upper arm 32 where the louver clip lower arm 31 is below the louver clip upper arm 32 when the pergola is in open position.
[0051] The post joint 39 provides a pivoting mount for the louver clip 30. The actuator bar 44 can be optionally mounted underneath the track 55. A track groove 56 can extend through the track 55. The track is preferably integrally formed with the crossbeam 59.
[0052] As seen in Fig. 5, a close-up of a left or right row of louver clips 30 shows an inside post 21 parallel to an outside post 22, where both are made of flat steel or aluminum members. The parallel posts can be secured by bolts to the track 55 on a left and right side of the track 55. The louver clip 30 has a louver clip lower arm hook 33 with a lower arm hook edge 35. The clip flange mount 37 may bisect the left and right edges of the louver clip 30. The flange pivot 38 is below the post joint 39 when the link 41 retracts the pivot link 53 to an open position. The link 41 has a first link connection 42 at one end and a second link connection at a second end. The link 41 preferably has one or more link bends 47 2 allow overlapping with adjacent links such that a first link connection opening 49 of a link overlaps with a second link connection opening 48 of an adjacent link.
[0053] The first connection openings and the second connection openings fit over the stem 50. The stem 50 has a stem base 51 with a larger radius then a radius of the stem 50. The stem 50 may also have a stem connection opening 52. The stem base 51 is preferably disc-shaped and can have one or more disc-shaped members that fit into one or more track grooves 56 in an aluminum extrusion that is horizontally oriented. The stem slot 57 preferably passes through the stem 50 to allow free rotation of the pivot link 53 relative to the stem connection opening 52.
[0054] As seen in Fig. 6, the transmission axle 71 rotates in a clockwise and counterclockwise direction. When a user pulls the close pull cord 74 attached to the close pull junction 75, the transmission axle 71 rotates. The transmission axle 71 is connected to the actuator pivot arm 77. The actuator coupler 76 is hinged to the actuator bar 44. The actuator coupler 76 can be formed as a bar having an open pull junction 74 on one side, and having a close pull junction 75 on another side. The actuator coupler 76 is preferably rigidly mounted to the actuator pivot arm 77. The actuator pivot ami 77 is mounted to the
84728351.1 actuator bar 44 at an actuator pivot arm joint 78.
[0055] The actuator bar 44 is preferably mounted to the actuator link 45 at an actuator bar joint 79. A pair of actuator bars actually a left and right set of louver clips 30. Fig. 6, can be a left row or right row of louver clips. Thus, the stem 50 is connected to an adjacent stem 150 which is in turn chained to a subsequent stem 250 in a sequential chain configuration. Similarly, the link 41 is preferably connected to an adjacent link 141 which is in turn connected to a subsequent link 241. For example, twelve links can connect eleven stems on the right side, and then another twelve links can connect eleven stems on a left side.
[0056] As seen in Fig. 7, the louvers can nest with each other to create a fully closed roof 5 structure or wall structure.
[0057] As seen in Fig. 8, a first row of louver clips 131 can be a right row of louver clips and second row of louver clips 132 can be a left row of louver clips and can be mounted on two crossbeams. A third row of louver clips 133 can be mounted parallel to the two crossbeams on a third crossbeam for example. The stem 50 is connected to an adjacent stem 150, which is in turn 10 chained to a subsequent stem 250 in a sequential chain configuration. The links are modular and can be removed. For example, a link can be removed so that the pergola is split into more than one section. For example, in a multi-section pergola, a first pergola section can be closed and a second pergola section can be open.
[0058] A key feature of the present invention is that the play in the link is tuned properly. The 15 first link connection connects to an adjacent stem, and the second link connection connects to a subsequent stem in a sequential chain. Each link has a small amount of play to prevent binding because each link is activated sequentially when the closing and opening action is reversed. Since each link is activated sequentially, subsequent links are not affected so then not all of the louver panels or blades need to be started in motion simultaneously. Avoiding simultaneous 20 motion startup minimizes binding when link tolerances are tuned to an appropriate amount.
