The mounting bracket 130 may define a bore 133 that extends through the arm 135 and/or the base 132. The bore 133 may be configured to receive electrical wiring (e.g., the electrical wiring 180 shown in
When the end portion 114 is fully received in the channel 138, the center of the attachment member 134 may be aligned with the center of the roller tube 110 along the longitudinal axis 112. As shown in
The arm 135 of the mounting bracket 130 may extend a distance D2 from the rear surface 153 of the base 132. The arm 135 may define a distal end 143. The distance D2 may be measured from the rear surface 153 to the distal end 143 and may be, for example, approximately three inches. The distance D2 may be based on a thickness of the flexible material 120 and/or the height of the window. When the mounting bracket 130 is wall-mounted, the spring 170 may be configured to lock the end portion 114 of the drive assembly 160 in the radial direction R. When the mounting bracket 130 is ceiling-mounted, the spring 170 may be configured to lock the end portion 114 of the drive assembly 160 in the transverse direction T.
The attachment member 134 and the arm 135 of the mounting bracket 130 may be sized to minimize (e.g., reduce) a light gap between an edge of the flexible material 120 and the structure. The outer surface 127 of the arm 135 may be distal from the end portion 114 of the drive assembly 160. The attachment member 134 may define an inner surface 128, which may face the end portion 114 of the drive assembly 160. The arm 135 and the attachment member 134 may be sized such that the outer surface 127 is a distance D3 from the inner surface. The arm 135 may be characterized by a distance D4 (e.g., a width) between the outer surface 127 and an inner surface 142, which may be, for example, approximately 0.20 inches. The distance D4 is large enough to allow the bore 133 to travel through the arm 135 from the base 132 to the channel 138 of the attachment member 134. The attachment member 134 may be characterized by a distance D5 (e.g., a width) between the inner surface 142 of the arm 135 and the inner surface 128 of the attachment member 134, which may be, for example, approximately 0.25 inches. The distance D3 may be, for example, approximately 0.45 inches. The distance D3 may define a minimum light gap that may exist between the edge of the flexible material 120 and the structure. For example, the distance D3 may be configured such that the minimum light gap is 0.5 inches or less.
The attachment member 134 along with the sliding cover 136 may provide a buffer space (e.g., at least the distance D5) between the edge of the flexible material 120 and the inner surface 142 of the arm 135. As the flexible material 120 is raised and lower on the roller tube 110, the position of the edge of flexible material 120 that is wrapped around the roller tube 110 may shift along the longitudinal direction L, which may be referred to as “telescoping” of the flexible material. As previously mentioned, the diameter of the sliding cover 136 may be equal to or less than the diameter of the roller tube 110. When the edge of the flexible material 120 moves towards the arm 135 of the mounting bracket 130, the edge of the flexible material 120 may overlap (e.g., hang over) the attachment member 134. The distance D5 may be sized to ensure that the flexible material 120 does not contact the inner surface 142 of the arm 135, which could potentially damage the flexible material. When the flexible material 120 has certain sizes (e.g., large dimensions) and thicknesses, a gap may be provided between the edge of the flexible material 120 and an end surface 166 of the ring portion 164 to provide additional space between the edge of the flexible material and the inner surface 142 of the arm 135 of the mounting bracket 130. The ring portion 164 may have the same color and/or finish as the arm 135 and the sliding cover 136 of the mounting bracket 130, such that the ring portion 164 blends in with the other parts of the motorized window treatment 100 and is not as noticeable when the ring portion 164 is exposed.
The mounting bracket 130 may include a spring 170. The spring 170 may be secured within the channel 138. The spring 170 may be configured to secure the end portion 114 of the drive assembly 160 within the channel 138. For example, the spring 170 may be configured to engage the end portion 114 of the drive assembly 160 such that the roller tube 110 is secured in a direction perpendicular to the structure. The spring 170 may be configured to flex as the end portion 114 of the drive assembly 160 is inserted into the channel 138.
The mounting brackets 130A, 130B at each end of the roller tube 110 may similar geometries (e.g., may be identical). However, only one of the two mounting brackets 130A, 130B may have the electrical wiring 180 extending through the bore 133 and the channel 138. Although the electrical wiring 180 and the plug 182 are shown in
The attachment member 134 may include a drum 137 (e.g., a cylindrical drum). The drum 137 may extend from the inner surface 142 of the attachment member 134. The drum 137 may extend in the longitudinal direction L. The drum 137 may define an outer surface 139. The drum 137 may be configured to receive the end portion 114 of the drive assembly. For example, the drum 137 may define the channel 138. The sliding cover 136 may be received by the drum 137 and may surround the drum 137. The sliding cover 136 may operate around the drum 137 from the closed position to the open position. For example, the sliding cover 136 may be configured to partially surround the outer surface 139 of the drum 137. When the sliding cover 136 is in the closed position, the channel 138 and the end portion 114 of the drive assembly 160 are not accessible. When the sliding cover 136 is in the open position, the channel 138 and the end portion 114 of the drive assembly 160 may be exposed.
The sliding cover 136 may be configured to retain the end portion 114 of the drive assembly 160 or the end portion of the idler within the channel 138. For example, the sliding cover 136 may prevent the end portion 114 of the drive assembly 160 or the end portion of the idler from becoming disengaged from the channel 138 when the sliding cover is in the closed position. When the mounting bracket 130 is wall-mounted and the sliding cover 136 is in the closed position, the sliding cover 136 may be configured to lock the end portion 114 of the drive assembly 160 or the end portion of the idler in the radial direction R. When the mounting bracket 130 is ceiling-mounted and the sliding cover 136 is closed, the sliding cover 136 may be configured to lock the end portion 114 of the drive assembly 160 or the end portion of the idler in the transverse direction T.
The sliding cover 136 may include a rib 175 extending from an inner surface of the sliding cover (e.g., towards the attachment member 134). The central rib 175 may stretch between the ends of the sliding cover 136. The central rib 175 may be received in a slot 176 in the drum 137 of the attachment member 134. The slot 176 may stretch around the circumference of the drum 137.
The sliding cover 136 may provide a secondary means of locking the end portion 114 of the drive assembly 160 in the channel 138 (e.g., in addition to the spring 170). Alternatively, if the attachment member 134 has a flat front surface, the sliding cover 136 may be straight and may be configured to slide linearly (e.g., up or down) to move between the closed position and the open position (e.g., to slide out of the way of the channel 138).
The sliding cover 136 may define one or more barbs or other type of protrusion (not shown) that may extend from, for example, the rib 175. The barbs may be configured to secure the sliding cover 136 in a closed position or an open position. The drum 137 may define one or more notches or detents (not shown) that may be located in, for example, the slot 176. The notches may be configured to receive a respective barb of the barbs. For example, the sliding cover 136 may define two barbs positioned at distal ends of the sliding cover 136.
As shown in
The end portion of the idler may a similar shape at the end portion 114 of the drive assembly 160 in order to be received in the channel 138 of the mount bracket 130 at the idler end of the roller tube 110. The end portion of the idler may not include the user interface 118 or the socket 116.
The channel 138 may define an opening 141 at a distal end 143 of the attachment member 134. The opening 141 may be a slot on the outer surface 139 of the drum 137. The channel 138 may extend from the opening 141 to a rear wall 146. The electrical wiring 180 may be received within the channel 138 via the bore 133. The channel 138 may be configured to retain the electrical wiring 180. The bore 133 may begin at the rear wall 146 of the channel 138 and may extend through the attachment member 134 and/or base 132. Additionally or alternatively, the mounting bracket 130 may include a socket (not shown). As an example, the socket may be located where the bore 133 meets the channel 138. The socket may be configured to receive a plug (not shown) that is attached to the drive assembly 160 via an electrical wiring (not shown).
The channel 138 may define slots 144 on either side of the channel 138. The slots 144 may be configured such that the channel 138 is T-shaped (e.g., has a T-shaped cross section). The slots 144 may be defined by flanges 147 defined by the drum 137. The flanges 147 may be configured to retain the end portion 114 of the drive assembly 160 within the channel 138. The flanges 147 may be configured to secure the roller tube in the transverse direction T. The channel 138 may define a side wall 148. The channel 138 may be configured such that the side wall 148 defines the intersection of the drum 137 and the inner surface 142 of the attachment member 134.
The spring 170 may be secured to the attachment member 134, for example, within the channel 138. For example, the spring 170 may be secured to the side wall 148 of the channel 138. As shown in
In addition, a spring (e.g., the spring 170) could be secured to the end portion 114 of the drive assembly 160. The channel 138 of the mounting bracket 130 could include a protuberance (not shown) around which the spring may flex as the end portion 114 is inserted into the channel. When the end portion 114 is fully inserted into the channel 138, the protuberance may exert a force on the spring for retaining the end portion.
The attachment member 134 may define flanges 147A, 147B along the channel 138. The flanges 147A, 147B may correspond to slots 144A, 144B. The slots 144A, 144B may be configured such that the channel 138 is T-shaped. The slots 144A, 144B may be configured to receive the end portion 114 of the drive assembly 160. The flanges 147A, 147B may be configured to secure the roller tube along the longitudinal direction L (e.g., along the longitudinal axis 112 shown in
The mounting bracket 230 may include a sliding cover 236, which may be rotatably received by the attachment member 234. The sliding cover 236 may be rotated between a closed position as shown in
The attachment member 234 may define a channel 238 that may be configured to receive the end portion 114 of the drive assembly 160 (e.g., configured for sliding receipt of the end portion). For example, the channel 238 may be configured to receive the end portion 114 of the drive assembly 160 when the sliding cover 236 is in the open position. The sliding cover 236 may be configured to cover the channel 238 and the end portion 114 of the drive assembly 160 when the end portion 114 is fully received within the channel 238. The sliding cover 236 may be configured to retain the end portion 114 of the drive assembly 160 within the channel 238. For example, the sliding cover 236 may cover the channel 238 and may retain the end portion of the drive assembly 160 within the channel 238 when the sliding cover 236 is in the closed position. The channel 238 may be configured to lock the roller tube 110 in position along the longitudinal direction L (e.g., along the longitudinal axis 112) such that translational movement of the roller tube in the longitudinal direction L is prevented. The channel 238 may have a T-shaped cross section. For example, the channel 238 may be configured to receive a wider cross section at the end portion 114 of the drive assembly 160. The channel 238 may define one or more flanges 247 to secure the end portion 114 within the channel 238. For example, the flanges 247 may engage the end portion 114 of the drive assembly 160 such that movement of the roller tube 110 in the longitudinal direction L is prevented.
The mounting bracket 230 may define a bore 233 that extends through the arm 235 and/or the base 232. The bore 233 may be configured to receive electrical wiring (e.g., the electrical wiring 180 shown in
The depressions 254A, 254B may define (e.g., two) attachment areas. The attachment areas may be located on each side of the base 232 and may be separated by a central portion of the base 232. For example, the base 232 may define a first attachment area in an upper portion and a second attachment area in a lower portion. The base 232 may also define a wall box hiding area (e.g., the central portion) between the attachment areas where the electrical wall box 190 may be positioned on the structure to which the mounting bracket 230 is mounted in order to be hidden behind the base 232.
The base cover 290 may be installed on the base 232 as shown in
A base 232B of the second mounting bracket 230B may be spaced from the structure 202 by one or more shims 260 (e.g., two shims 260), for example, to align the center of the attachment member 234B to the center of the attachment member 234A. The one or more shims 260 may be used to account for the distance D9. For example, the one or more shims 260 may have a thickness substantially equal to the distance D9.
The attachment members 334A, 334B of the center mounting bracket 330 may be similar to the attachment member 234 of the mounting bracket 230 shown in
The center mounting bracket 330 may define bores 333A, 333B that each may extend from the channels 338A, 338B of the respective attachment members 334A, 334B through the arm 335 and/or the base 232. The bores 333 may each be configured to receive electrical wiring (e.g., the electrical wiring 180 shown in
The holes 356A, 356B may define a first attachment area of the base 332, and the holes 356C, 356D may define a second attachment area on the opposing side of the base 332. The base 332 may define a wall box hiding area between the first and second attachment areas. An electrical wall box (e.g., the electrical wall box 190) may be positioned on the structure to align with the wall box hiding area of the center mounting bracket 330. For example, the electrical wall box 190 may be such that it is hidden behind the base 332 of the center mounting bracket 330.
The jamb mounting bracket 430 may define holes 456A, 456B therethrough. The holes 456A, 456B may be configured to receive fasteners (not shown) for securing the jamb mounting bracket 430 to a structure (e.g., a wall or a window jamb). The holes 456A, 456B may be configured such that the fasteners are countersunk with respect to an inner surface 445 of the drum 437. The jamb mounting bracket 430 may define a flat surface 458 on one side that may aide in aligning the jamb mounting bracket during installation. For example, an installer may place a spacer that has parallel planar surfaces (e.g., a block of wood or a level) against the structure (e.g., so that a first planar surface of the spacer is against the structure), and place the flat surface 458 of the jamb mounting bracket 430 against the second parallel planar surface of the spacer. The installer may then drive the fasteners through the holes 456A, 456B while the flat surface 458 of the jamb mounting bracket 430 is against the second planar surface of the spacer.
The attachment member 434 of the jamb mounting bracket 430 (e.g., the drum 437) may define a channel 438. The channel 438 may define an opening 441. The opening 441 may be a slot on an outer surface 439 of the drum 437. The channel 438 may extend from the opening 441 to a rear wall 446. Although not shown in
The channel 438 may define slots 444 on either side of the channel 438. The slots 444 may be configured such that the channel 438 is T-shaped (e.g., has a T-shaped cross section). The slots 444 may be defined by flanges 447 that are defined by the drum 437. The flanges 447 may be configured to retain an end portion of a drive assembly within the channel 438. The flanges 447 may be configured to secure the roller tube in the transverse direction T. The channel 438 may define a side wall 451. The side wall 451 may be a forward surface of the base 432.
The jamb mounting bracket 430 may include a spring 470. The spring 470 may be secured to the jamb mounting bracket 430, for example, within the channel 438. For example, the spring 470 may be secured to the side wall 451 of the channel 438. The spring 470 may be secured in the channel 438 using one or more fasteners 472 and/or one or more bosses 471. The spring 470 may be positioned at the opening 441 of the channel 438, for example, using the bosses 471. For example, a forward edge 476 of the spring 470 may be aligned with the opening 441 and/or an outer edge 443 of the jamb mounting bracket 430. The forward edge 476 may engage the side wall 451 such that the forward edge 476 is substantially flush with the side wall 451. The spring 470 may include compliant fingers 474 that are configured to engage the side wall 451 and bias a rear edge 478 of the spring 470 away from the side wall 451. For example, the rear edge 478 may be spaced away from the side wall 451. The compliant fingers 474 may be configured to flex as the end portion of the drive assembly is inserted into the channel 438. For example, the end portion of the drive assembly may apply a force on the spring 470 that pushes the rear edge 478 closer to the side wall 451. When the roller tube is fully inserted into the channel 438, the compliant fingers 474 may enable the rear edge 478 to exert a force on the end of the drive assembly such that the end is retained within the channel 438. The rear edge 478 may exert the force on the end of the drive assembly in the radial direction R.
The sliding cover 436 may define one or more barbs (not shown). The barbs may be configured to secure the sliding cover 436 in a closed position or an open position. The drum 437 may define one or more notches (not shown). The notches may be configured to receive a respective barb of the barbs. For example, the sliding cover 436 may define two barbs positioned at distal ends of the sliding cover 436.
The jamb mounting bracket 430 may define flanges 447A, 447B along the channel 438. The flanges 447A, 447B may correspond to slots 444A, 444B, respectively. The slots 444A, 444B may be configured such that the channel 438 is T-shaped. The slots 444A, 444B may be configured to receive an end portion of a drive assembly. The flanges 447A, 447B may be configured to secure a roller tube along the longitudinal direction L (e.g., along the longitudinal axis 112 shown in
The motorized window treatment 500 may include a bracket cover 580 mounted over the attachment member 534 of the mounting bracket 530. The motorized window treatment 500 may include a base cover 590 mounted over the base 532 of the mounting bracket 530. Since the bracket cover 580 and the base cover 590 conceal the mounting bracket 530 and the base 532, respectively, the mounting bracket 530 and the base 532 are shown in dashed lines in
The bracket cover 580 may define a recess 582 for receiving the arm 535 of the mounting bracket 530. When the arm 535 is received in the recess 582, an outer surface 527 of the arm 535 may be adjacent to and/or abut an inner surface 583 of the recess 582. For example, the outer surface 527 may substantially flat and may have no features to allow for attachment to the inner surface 583 of the recess 582 (e.g., as shown by the outer surface 127 of the arm 135 of the mounting bracket 130 in
The bracket cover 580 may be installed over the arm 535 of the mounting bracket 530 (e.g., slid onto the arm 535) and then the base cover 590 may be installed over the base 532. The base cover 590 may be attached to the bracket cover 580, such that the base cover captures the bracket cover against the mounting bracket 530. The base cover 590 may include tabs 592 that may be inserted in respective recesses 594 in the base 532 of the mounting bracket 530. After the tabs 592 are received in the recesses 594 and pushed up against the structure to which the mounting bracket 530 is attached, the base cover 590 may be pushed towards the arm 535, such that the tabs 592 are captured under respective extensions 596 of the base 532 for holding the base cover 590 in place. The base cover 590 may include projections 598 that may be received in notches 586 of the bracket cover 580 for holding the bracket cover 580 against the mounting bracket 530.
The bracket cover 580 may include one or more magnets 584. The magnets 584 may be positioned adjacent to one or more metal elements (not shown) inside of the arm 535 of the mounting bracket 530 when the bracket cover 580 is mounted over the arm 535 of the mounting bracket 530. The magnets 584 may be configured to hold the bracket cover 580 against the arm 535 of the mounting bracket 530. In addition, the arm 532 of the mounting bracket 530 may comprise magnets (not shown) positioned adjacent to one or more metal elements (not shown) inside of the bracket cover 580 when the bracket cover is mounted over the arm for holding the bracket cover against the arm.
The bracket cover 580 could also be attached to an elongated support member (not shown) that may be connected to the structure (e.g., to the wall) adjacent to the mounting bracket and may extend from the wall parallel to the mounting bracket. The bracket cover 580 may define an opening (not shown) for receiving the elongated support member and may be configured to snap onto the elongated support member. When the bracket cover 580 is attached to the elongated support member, the magnets 584 of the bracket cover 580 may not be needed to hold the bracket cover 580 against the mounting bracket 530.
The bracket cover 680 may be configured to be mounted over the arm 635 of the bracket 630 (e.g., slid onto the attachment member). The bracket cover 680 may include a body 682 that defines a recess 684 for receiving the arm 635 of the mounting bracket 630. The bracket cover 680 may include feet 685 that extend from the body 682 (e.g., in the same direction as the base 632 extends from the arm 635 of the mounting bracket 630 when the bracket cover 680 is mounted over the arm). The feet 685 may be configured to mount the bracket cover 680 to (e.g., attaching the bracket cover 680 to) the window frame, wall, or other structure to which the mounting bracket 630 is mounted. The feet 685 of the bracket cover 680 may include respective openings 686 for receiving fasteners (not shown). The feet 685 may be attached to the body 682 via fasteners (not shown) received through openings 688 in the feet. The feet 685 may be detachable from the body 682 (e.g., by removing the fasteners in the openings 688) to enable the feet 685 to be attached to bracket covers of other shapes, sizes, and materials (e.g., to allow for ease of customization of the bracket covers).
After the bracket cover 680 is installed over the arm 635 of the mounting bracket 630, the base cover 690 may be installed over the base 632. The base cover 690 may include flanges 692 that may be received under respective flanges 689 on the feet 685 of the bracket cover 680. The base cover 690 may be pushed towards the arm 635 of the mounting bracket 630, such that the flanges 692 slide by and are captured under the respective flanges 689 of the feet 685 of the bracket cover 680.
As previously mentioned, an electrical wall box (e.g., the electrical wall box 190) may be located behind one of the mounting brackets 130, 230 and may be concealed by the mounting bracket. The main body 710 may include holes 716, 717, 718 for locating pilot holes for drilling a hole for the electrical wall box 190 behind one of the left, center, and right mounting brackets, respectively. The pilot holes for the electrical wall box 190 may (e.g., only) need to be drilled for the mounting brackets that have electrical wiring to be connected to the drive assembly 160 of the motorized window treatment 100. Each of the holes 716, 717, 718 may be surrounded by a respective outline that may be printed on the main body 710 and may indicate the outline of the electrical wall box 190 to be located behind the respective mounting bracket.
The bracket mounting jig 700 may include a spacing member 720. The spacing member 720 may be connected to the main body 710 via screws 722 received through respective slots 724 in the main body 710 and respective openings 726 in the spacing member 720. The screws 722 may have respective knobs 728 that may be grasped by a user and twisted to allow for loosening and tightening the screws. The spacing member 720 may be moved vertically with respect to the main body 710 by loosening the screws 722 and sliding the screws through respective slots 724.
The bracket mounting jig 700 may further include two locating members 730. The locating members 730 may be connected to the spacing member 720 via screws 732 received through respective slots 734 in the locating members 730 and respective openings 736 in the spacing member 720. The screws 732 may also have respective knobs 738 for loosening and tightening the screws. The locating members 730 may each be moved horizontally with respect to the spacing member 720 by loosening the screws 732 and sliding the screws through respective slots 734. In addition, the screws 732 may be fully removed from the openings 736 and inserted in other openings 736 of the spacing member 720 to adjust the horizontal position of the locating members 730.
The locating members 730 may be configured to be located in the corner of a window over which the mounting brackets are to be located. For example, when locating the pilot holes for the right mounting bracket, the right locating member 730 may be located in the upper right corner of the window. For example, the position of the spacing member 720 may be adjusted vertically and the position of the right locating members 730 may be adjusted horizontally until the holes 714 for the right mounting bracket are in the correct location. The same steps may be completed for locating the holes 712 for the left mounting bracket. When the spacing member 720 and the locating members 730 are in the desired positions, the respective screws 722, 732 may be tightened to lock the spacing member 720 and the locating members 730 in place. Accordingly, the pilot holes for the mounting brackets of multiple window treatments may be easily located by using the bracket mounting jig 700 with the locked spacing member 720 and locating members 730 at each window.
A ceiling mounting jig (not shown) may be used for installing the mounting brackets 130, 230 of the motorized window treatment 100 to a horizontal surface (e.g., inside of a window frame to the top surface of the window frame). The ceiling mounting jig may have a similar structure as the bracket mounting jig 700 shown in
A jamb mounting jig (not shown) may be used for installing the jamb mounting bracket 430 to a vertical surface (e.g., a wall and/or a side surface of a window frame).
After the mounting screws 830 are installed, the ears 814 may be removed (e.g., broken off, cut off, etc.) from the wall box 800 as shown in
At 922, electrical wiring may be run through the wall box and connected to electrical wiring within the structure (e.g., in the walls, ceiling, etc.). At 924, the drywall may be installed around the electrical wall box. At 926, the jig may be used to mark the location of pilot holes for the screws (e.g., fasteners) for the mounting bracket. For example, the jig may be aligned with the electrical wall box and/or the corner of the window at 926. At 928, the pilot holes for the screws may be drilled through the drywall and the support behind the drywall. At 930, electrical wiring (e.g., a window treatment harness with a plug) may be inserted through the bracket (e.g., through the bore 133, 233 with the plug on the side of the mounting bracket 130, 230 having the attachment member 134, 234). At 932, connectors may be connected to the electrical wiring extending through the bracket and the electrical wiring extending from the electrical wall box. At 934, the connectors may be plugged together and inserted into the electrical wall box. At 936, the screws may be driven into the pilot holes and the holes in the base of the mounting bracket to mount the mounting bracket.
At 938, the plug of the electrical wiring in the mounting bracket may be plugged into the connector on the drive assembly. The idler end of the roller tube may be inserted into the channel of one of the mounting brackets at 940 and the drive end of the roller tube may be inserted into the channel of the other mounting bracket at 942. At 944, power may be applied to the drive assembly 160 of the motorized window treatment. At 946, the drive assembly 160 may be configured using the buttons 117 of the user interface 118. At 948, the sliding cover of the mounting bracket may be closed and the installation procedure 900 may end. The installation procedure 900 may be repeated for mounting other motorized window treatments.
While the mounting brackets 130, 230, 330, 430, 530, 630 shown and described herein have circular front surfaces, the mounting brackets 130, 230, 330, 430, 530, 630 may also have differently-shaped front surfaces. For example, mounting brackets 130, 230, 330, 430, 530, 630 may have front surfaces of another shape, such as, for example, a rectangular shape (e.g., as shown on a mounting bracket 130′ in
While the bracket covers 580, 680 shown and described herein each has a circular front surface, each bracket cover may also have a differently-shaped front surface. For example, the bracket covers 580, 680 may each have a front surface of another shape, such as, for example, a rectangular shape (e.g., as shown on a bracket cover 580′ in
The motor drive unit 1000 may include a control circuit 1020 for controlling the operation of the motor 1010. The control circuit 1020 may include, for example, a microprocessor, a programmable logic device (PLD), a microcontroller, an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or any suitable processing device or control circuit. The control circuit 1020 may be configured to generate one or more drive signals VDR for controlling the motor drive circuit 1012. The one or more drive signals VDR may be configured to control the rotational speed and/or direction of rotation of the motor 1010.
The motor drive unit 1000 may include a rotational position sensor, such as, for example, a Hall effect sensor (HES) circuit 1022, which may be configured to generate one or more Hall effect sensor signals VHES. The one or more Hall effect sensor signals VHES may indicate a rotational speed and/or a direction of the motor 1010 to the microcontroller. The rotational position sensor may include other suitable position sensors, such as, for example, magnetic, optical, and/or resistive sensors. The control circuit 1020 may be configured to determine a rotational position of the motor 1010 in response to the Hall effect sensor signals VHES generated by the HES circuit 1022. The control circuit 1020 may be configured to determine a present position of the covering material in response to the rotational position of the motor 1010. The control circuit 1020 may be coupled to a memory 1024 (e.g., a non-volatile memory). The present position of the covering material and/or limits for controlling the position of the covering material (e.g., a fully open position and/or a fully closed position) may be stored in the memory 1024. The operation of a motor drive circuit and a Hall effect sensor circuit of an example motor drive unit is described in greater detail in commonly-assigned U.S. Pat. No. 5,848,634, issued Dec. 15, 1998, entitled MOTORIZED WINDOW SHADE SYSTEM, and commonly-assigned U.S. Pat. No. 7,839,109, issued Nov. 23, 2010, entitled METHOD OF CONTROLLING A MOTORIZED WINDOW TREATMENT, the entire disclosures of which are hereby incorporated by reference.
The motor drive unit 1000 may include a communication circuit 1026 that may allow the control circuit 1020 to transmit and receive communication signals, e.g., wired communication signals and/or wireless communication signals, such as radio-frequency (RF) signals. The motor drive unit 1000 may include a user interface 1028 having one or more buttons that allow a user to provide inputs to the control circuit 1020 during setup and/or configuration of the motorized window treatment. The control circuit 1020 may be configured to control the motor 1010 to control the movement of the covering material in response to a shade movement command received from the communication signals received via the communication circuit 1026 or the user inputs via the buttons of the user interface 1028. The user interface 1028 may include one or more light-emitting diodes (LEDs) that may be illuminated by the control circuit 1020, for example, to provide feedback to the user of the motorized window treatment.
