Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.
DETAILED DESCRIPTION
With reference to FIGS. 1-7, a covering 10 (e.g., a window shade, etc.) including a mounting assembly 14 for covering an architectural opening (e.g., a window, a C-channel, etc.) is illustrated. The mounting assembly 14 includes a pair of brackets 18, a chain diverter 22, and a diverter shaft assembly 26. Each bracket 18 is respectively coupled to an opposing end of the diverter shaft assembly 26 to support the diverter shaft assembly 26. However, for sake of brevity, only one side of the mounting assembly 14 is illustrated and discussed in detail. The opposing side is a mirror image of the mounting assembly 14, with like numbers identifying like components. The mounting assembly 14 includes at least one diverter 22 (or chain diverter 22 or continuous loop operator diverter 22) coupled to one of the brackets 18. In other embodiments, each bracket 18 can includes a respective chain diverter 22. The covering 10 also includes a roller assembly 30, parts of which are not shown or otherwise schematically shown for clarity purposes. The covering 10 is supported by the mounting assembly 14 within the architectural opening. As explained in greater detail below, the mounting assembly 14 advantageously positions the roller assembly 30 in a consistent, aesthetically pleasing manner and utilizes the same components for both sides of the assembly to minimize the number of unique parts.
The mounting assembly 14 is configured for assembly in, for example, an architectural channel above the architectural opening (see, for example, C-channel 315 of FIGS. 10-11). These channels include an opening (i.e., a slot) (see, for example, opening 316 of FIGS. 10-11) through which the covering extends to cover the architectural opening. In particular, some architectural designs are constrained in such a way that the mounting channel is a compact space. In addition, the channel geometry may vary from building to building or even opening to opening. As such, these mounting channels present specific challenges for mounting a covering. The mounting assembly 14 is also configured for assembly in other types of architectural openings (e.g., a window frame, etc.). The mounting assembly 14 can be mounted within the center of an opening (or a center of the pocket) defined by an architectural opening, even when the mounting space itself may not be centered with respect to the opening (FIGS. 10-11). With the mounting assembly 14, the covering 10 extends through the center of the opening defined by the architectural opening, regardless of length, thereby providing a consistent aesthetic look.
With reference now to FIGS. 1-3, the bracket 18 includes a first portion 34, a second portion 38, and a third portion 42. The second portion 38 extends between the first portion 34 and the third portion 42. In the illustrated embodiment, the second portion 38 is approximately orthogonal to the first portion 34. The third portion 42 is connected to the second portion 38 by a connecting portion 46 that is angled with respect to both the second portion 38 and the third portion 42. As such, in the illustrated embodiment, the second portion 38 extends offset from and parallel to the third portion 42. While the illustrated connection portion 46 is oblique to the second and third portions 38, 42, in other embodiments, the connection portion 46 can be orthogonal to the second and third portions 38, 42.
With reference to FIGS. 2 and 3, the first portion 34 includes a first plurality of mounting apertures 50, while the second portion 38 includes a second plurality of mounting apertures 54. The first plurality of mounting apertures 50 and the second plurality of mounting apertures 54 are configured to receive a fastener 226 (FIG. 9A) to mount the bracket 18 to an architectural opening. The first plurality of mounting apertures 50 and the second plurality of mounting apertures 54 can be used individually or cooperatively. While a plurality of apertures 50, 54 are shown, additional embodiments can include any number of apertures on either the first portion 34 or the second portion 38. As explained in greater detail below, the third portion 42 of the bracket 18 includes slots 58 for receiving the roller assembly 30, a plurality of positioning apertures 62 for coupling the chain diverter 22 to the bracket 18, and a keyhole 66 for coupling the diverter shaft assembly 26 to the bracket 18.
With reference to FIGS. 4, 5, and 7, the chain diverter 22 is coupled to the bracket 18 by two fasteners 70 (e.g., rivets, projections, etc.). Each fastener 70 passes through one of the plurality of positioning apertures 62. However, not all of the positioning apertures 62 receive a fastener 70, as the additional mounting apertures 62 on the bracket 18 allow the chain diverter 22 to be coupled to the bracket 18 in at least two configurations. In the illustrated embodiment, there are four apertures 62 on the bracket 18 and two of which are used to couple the chain diverter 22 to the bracket 18. As such, the chain diverter 22 in the illustrated embodiment can be positioned relative to the bracket 18 in at least two positions. In a first configuration, the chain diverter 22 is positioned in a forward position (FIG. 2) utilizing two of the four positioning apertures 62. In a second configuration, the chain diverter 22 is positioned in a rearward position (not shown) utilizing the other two of the four positioning apertures 62. Mounting the chain diverter 22 to the positioning apertures 62 associated with the rearward position can be utilized, for example, to ambidextrously mount the chain diverter 22 to the bracket 18 on the opposite side of the mounting assembly 14, where in fact, the “rearward position” would appear as a “forward position.” The chain diverter 22 includes a window 63. The window 63 is elongated so it does not obstruct the keyhole 66, regardless of the position of the chain diverter 22. The flexibility in how and where the chain diverter 22 is coupled to the bracket 18 reduces the number of unique components required for assembly of the mounting assembly 14. In other words, the bracket 18 and the chain diverter 22 are ambidextrous components such that they can be utilizing on either side of the mounting assembly 14. Furthermore, the adjustability allows the bracket 18 and the chain diverter 22 to be utilized in different sized spaces or openings.
With continued reference to FIGS. 4, 5, and 7, the chain diverter 22 includes a guide portion 74 with a slot 78 and a non-linear opening 82. Specifically, the slot 78 is at least partially formed by a first flange 86 and a second flange 90. The first flange 86 includes a first curved edge 94 and the second flange 90 includes a second curved edge 98. The two curved edges 94, 98 are spaced apart to define the non-linear opening 82. The non-linear opening 82 extends from a top edge 102 of the flanges 86, 90 to a bottom edge 106 of the flanges 86, 90. As explained in greater detail below, the guide portion 74 is configured to receive a chain 126 (or continuous loop operated 126) and to maintain the chain 126 in a spaced relationship from any interfering structure.
With reference to FIGS. 1-7, the roller assembly 30 is coupled to the bracket 18. The roller assembly 30 includes a drive assembly 110 (FIG. 9B) and a material roll 114, schematically shown in FIGS. 1, 6A, and 6B. The roller assembly 30 can include additional components, which are not illustrated or shown schematically for purposes of clarity (e.g., the material roll 114, etc.). The drive assembly 110 includes a drive roller 118, a clutch 122, a bead chain 126 (or continuous loop operator 126), and a hold down device 130. With particular reference to FIG. 2, the drive assembly 110 further includes hooks 132 that are received within the slots 78 formed on the bracket 18 in order to couple the roller assembly 30 to the bracket 18.
The material roll 114 (schematically shown in FIG. 1) includes a covering material 134 (e.g., a solar shade material, vinyl shade material, etc.) (FIGS. 6A and 6B) and a tube 138 (FIG. 1) that supports the covering material 134. Specifically, the covering material 134 is coupled to the tube 138 and configured to be wound around and unwound from the tube 138 (e.g., a roller shade, etc.). The material roll 114 can include a roll of window covering material (or shade material), for example a roller shade. A hem bar 142 (see FIGS. 1-3) can be coupled to a bottom edge of the covering material 134. The drive roller 118 is drivingly coupled to the material roll 114 and is operable to rotate relative to the bracket 18 about a first rotational axis 146. In operation, translation of the chain 126 (FIG. 9C) by a user rotates the drive roller 118 through the clutch 122, which causes rotation of the material roll 114. Based on the translational direction of the chain 126 (FIG. 9C), the material roll 114 can either wind or unwind the covering material 134 from the tube 138.
Referring now to FIGS. 3-5, the diverter shaft assembly 26 includes a hollow shaft 150 (i.e., a tube), an end cap 154, an insert 158, and a fastener 162. The end cap 154 is coupled to the insert 158 by the fastener 162, and the insert 158 is received within the hollow shaft 150. The diverter shaft assembly 26 is coupled to the bracket 18 by an interference fit with a portion of the keyhole 66 formed on the bracket 18. In particular, the keyhole 66 includes an enlarged portion 166 and a fitted portion 170. To couple the shaft assembly 26 to the bracket 18, the end cap 154 is first inserted through the enlarged portion 170 of the keyhole 66 and then translated into the fitted portion 174. With particular reference to FIG. 5, the end cap 154 includes a grooved section 178 that is received within the fitted portion 174 of the keyhole 66. The end cap 164 does not rotate with respect to the bracket 18, but the insert 158 and the shaft 150 rotate about a rotational axis 182 (shown in FIGS. 1-3 and 5) defined by the fastener 162. In other words, the insert 158 and the shaft 150 rotate relative to the end cap 154 and the bracket 18 along the rotational axis 182. In the illustrated embodiment, the rotational axis 182 of the shaft 150 is offset from the rotational axis 146 of the drive roller 118 in at least two directions (i.e., vertically and horizontally) (FIG. 2). In other embodiments, the rotational axis 182 of the shaft 150 can be offset from the rotational axis 146 of the drive roller 118 in one direction (e.g., vertically, or spaced apart along a vertical axis 311 (FIG. 10), etc.) and aligned with the rotational axis 146 of the drive roller 118 in one direction (e.g., not offset horizontally along a horizontal axis 312 (FIG. 10), or in alignment along the vertical axis 311 (FIG. 10), etc.). In some embodiments, the diverter shaft assembly 26 is utilized in applications that do not require a chain or chain diverter (e.g., motorized shade applications). In particular, the diverter shaft assembly 26 can be utilized in a motorized shade, which would not need a chain and therefore would not need a chain diverter.
With reference to FIGS. 6A and 6B, the covering material 134 includes a first portion 186 that extends between the material roll 114 and the shaft 150. The covering material 134 further includes a second portion 190 that extends from the shaft 150 and extends within a plane 194. The first portion 186 and the second portion 190 of the covering material 134 form a continuous, uninterrupted length of material. In other words, material passes from the first portion 186 to the second portion 190 as the covering material 134 unwinds from the tube 138, and likewise, material passes from the second portion 190 to the first portion 186 as the covering material 134 winds around the tube 138. The second portion 190 of the covering material 134 may be a first length L1 (FIG. 6A) that extends within the plane 194, or may be a second length L2 (FIG. 6B) that also extends within the plane 194. In other words, the covering material 134 includes the second portion 190 that extends from the shaft 150 in the plane 194, regardless of the length the second portion 190 extends from the shaft 150. In the illustrated embodiment, the shaft 150 at least partially defines the plane 194, with the plane 194 being tangential to an outer diameter of the shaft 150 (or defined by a portion of the circumference of the shaft 150). This provides greater control and consistency of placing the covering material 134 and offers improved aesthetics by centering the covering material in the architectural opening as compared to conventional shades. In other words, the covering material in conventional coverings can shift where the covering material hangs (i.e., laterally shifts front to back, or perpendicular to plane 194) with respect to the architectural opening depending on how much covering material is paid out (or unwound from the tube 138), which can be visibly noticeable and not aesthetically pleasing. In addition to an aesthetic improvement, precise control of the placement (or position) of the covering material 134 within the architectural opening reduces the size of the opening required to accommodate the covering 10.
With continued reference to FIGS. 6A and 6B, the chain diverter 22 defines a centerline 198 that extends within the plane 194, which can be coplanar with the second portion 190 of the covering material 134. The chain diverter 22 can be mounted within the center of an opening (or center of the pocket) defined by the architectural opening, even when the bracket 18 itself may not be centered relative to the opening (see FIGS. 10-11). As such, the covering material 134 extends through the center of the opening defined by the architectural opening after contacting the diverter shaft assembly 26, regardless of length, thereby providing a consistent aesthetic look. The mounting assembly 14 also consistently positions the covering material 134 in a centered position for a variety of different sized and shaped architectural openings. The positional adjustability of the mounting assembly 14 advantageously improves aesthetics for different sized and shaped architectural openings.
With reference to FIGS. 8 and 9A-9I, a method 210 of installing the covering 10 in an architectural opening 214 is illustrated. The mounting assembly 14 and the method 210 of installing provide certain advantages, explained below, that improve the safety, reliability, cost, and flexibility of the covering 10. With reference to FIG. 8, the method 210 includes step 218, by coupling the chain diverter 22 to the bracket 18 (e.g., via rivets 70). As explained above, the chain diverter 22 may be coupled to the bracket 18 in at least two configurations, such that the same bracket 18 and the same chain diverter 22 can be used on both sides of the mounting assembly 14.
Next, at step 222, the bracket 18 and the chain diverter 22 are coupled to the architectural opening 214. As shown in FIG. 9A, the first portion 34 of the bracket 18 is coupled to the architectural opening 214 via fasteners 226.
At step 230, the roller assembly 30 is mounted to the bracket 18 (FIG. 9C). The drive assembly 110 (shown in FIG. 9B) is coupled to the bracket 18 by the hooks 132 (shown FIG. 7). The material roll 114 is then coupled to the drive assembly 110. In other embodiments, step 230 can include coupling the drive assembly 110 to the bracket 18, with the material roll 114 being coupled to the drive assembly 110 at a later point in the installation method (for example after step 254).
Next, at step 234 the continuous loop operator 126 (or chain 126) is inserted into the diverter 22. In embodiments where the continuous loop operator 126 is a chain 126, the chain 126 is generally inserted into the diverter 22 after the chain 126 is formed into a complete, continuous loop. As shown in FIG. 9B, prior to insertion into the diverter 22, the continuous loop operator 126 can be engaged with the hold down device 130. An example of the hold down device 130 is disclosed in U.S. Pat. No. 9,663,988, the content of which is hereby incorporated by reference in its entirety. With reference to FIG. 9D, a leading portion 238 of the continuous loop operator 126 is inserted into the diverter 22. With reference to FIG. 9E, a trailing portion 242 of the continuous loop operator 126 is then inserted into the chain diverter 22. In the illustrated embodiment where the continuous loop operator 126 is the chain 126, the chain 126 is inserted into the diverter 22 by passing a spacing 246 between adjacent chain balls 250 through the non-linear opening 82 formed in the guide portion 74 of the chain diverter 22. Once the chain 126 passes through the non-linear opening 82, the chain 126 is retained within the slot 78. FIG. 9F illustrates the completed step 234, with both the leading portion 238 and the trailing portion 242 of the chain loop 126 being positioned within the chain diverter 22.
With continued reference to FIGS. 9E-9F, the geometry of the non-linear opening 82 prevents the continuous loop operator 126 (or chain 126) from inadvertently leaving the slot 78 during operation. In other words, the chain 126 may be simply inserted into and removed from the guide portion 74 when desired, but is otherwise prevented from leaving the guide portion 74 during normal operation. At the same time, the chain diverter 22 positions the chain 126 in a forward-most position for ease of access by a user and to also space the chain 126 from any interfering structure (e.g., the covering material 134). This improved spacing of the chain 126 helps reduce the wear of the chain 126 and any potentially interfering structure, and reduces the tendency of the chain 126 to become free from the clutch 122.
Next at step 254, the hold down device 130 is coupled to the architectural opening 214 (FIG. 9G). The hold down device 130 is provided as a safety feature to prevent unintentional entanglement in the chain 126. The mounting assembly 14 and the method 210 advantageously allows for assembly of the covering 10 while the chain 126 is maintained in a complete loop. In this way, the hold down device 130 does not need to be removed from the chain 125 during installation. For example, an installer may physically remove the chain hold-down from engagement with the chain during installation, and then fail to reattach once completed. In other words, for conventional coverings, the chain loop must be broken (i.e., separated) by an installer in order to complete installation. By breaking the chain loop during installation, the risk that the chain hold-down may not be installed in increased. In contrast, the driving assembly 110 of the present invention can be provided as a single assembly (FIG. 9B) that includes the hold down device 130 on the complete chain loop 126, which does not need to be broken in order to complete installation. As a result, safety is improved by ensuring the hold down device 130 remains in engagement with the chain 126 during installation.
At step 258, the diverter shaft assembly 26 is mounted to the bracket 18. FIG. 9H illustrates the diverter shaft assembly 26 with the end cap 154 and the insert 158 removed from the shaft 150. FIG. 9I illustrates the completion of step 258, with the diverter shaft assembly 26 mounted within the keyhole 66 formed in the bracket 18. As described above, mounting the diverter shaft assembly 26 includes inserting the end cap 154 into the enlarged section 170 and then translating the end cap 154 into the fitted section 174 of the keyhole 66.
Next, at step 262 the covering material 134 is routed over the diverter shaft assembly 26. In other words, the covering material 134 is routed from the material roll 114 to contact or otherwise pass over the diverter shaft 150. Once past the diverter shaft assembly 26, the covering material 134 extends from the shaft 150 within the fixed plane 194, which is centrally aligned with respect to the architectural opening, regardless of length.
FIGS. 10-12C illustrate another embodiment of a covering 310 (e.g., a window shade) including a mounting assembly 314 for mounting the covering 310 within an architectural opening (e.g., a window, a C-channel, etc.). The covering 310 is substantially similar to covering 10, and only the differences are described herein, with similar structure referenced with the same reference numerals incremented by “300” (e.g., 14 and 314 both reference the mounting assembly, etc.).
With reference to FIGS. 10 and 11, the mounting assembly 314 includes a bracket 318, a chain diverter 322, and a diverter shaft assembly 326. As before, the mounting assembly 314 supports a roller assembly 330. The covering 310 is illustrated mounted within a C-channel 315 that defines an opening 316, with which the chain diverter 318 is centered. The bracket 318 includes two different keyholes 366a, b to receive the diverter shaft assembly 326 in two potential, different configurations (e.g., positions along a second direction 312). The bracket 318 also includes nine positioning apertures 362 for selectively coupling the chain diverter 322 in at least six different positions. More specifically, the chain diverter 322 can be adjustably mounted to the bracket 318 in both a first direction 311 (i.e., vertically) and the second direction 312 (i.e., horizontally forward or aft). In the illustrated embodiment, the second direction 312 is orthogonal to the first direction 311.
With reference to FIGS. 12A-12C, three of the six possible positions for the chain diverter 322 are illustrated for three different C-channels 315A-315C. In particular, the three height-adjustable positions for the chain diverter 322 are shown in FIGS. 12A-12C, with FIG. 12A showing the highest mounting position for C-channel 315A, FIG. 12B showing an intermediate position for C-channel 315B, and FIG. 12C showing the lowest mounting position for C-channel 315C. The remaining three positions (not shown) are mirror images of the positions in FIGS. 12A-12C for positioning on the opposite side of the architectural opening. More specifically, the chain diverter 322 is positioned relative to the bracket 318 such that a window 363 of the chain diverter 322 is aligned with the other keyhole 366b, and the mounting apertures on the chain diverter 322 are aligned with the positioning apertures 362 on either side of the keyhole 366b.
FIG. 13-14 illustrate another embodiment of a covering 410 (e.g., a window shade) including the mounting assembly 14 for mounting the covering 410 within an architectural opening (e.g., a window, a C-channel, etc.). The covering 410 is substantially similar to covering 10, 310, and only the differences are described herein. Similar structure is referenced with the same reference numerals.
The mounting assembly 14 includes a first bracket 18a and a second, opposing bracket 18b. The first and second brackets 18a, 18b are mirror images of the same bracket. A diverter 422 is selectively coupled to the first bracket 18a. The brackets 18a, 18b support the roller assembly 30 and a diverter shaft assembly 426. More specifically, the first bracket 18a includes the drive assembly 110 and the associated drive roller 118. The roller assembly 30 includes the material roll 114. The material roll 114 couples to (or receives) the drive roller 118 of the drive assembly 110 at one end, and coupled to (or receives) an idler 423 at the second, opposite end. The idler 423 is received by a mounting aperture 424 defined by the second bracket 18b. The material roll 114 can include a depression 425 (or slot) that is keyed to an associated portion 425a of the drive roller 118 and associate portion 425b of the idler 423 to facilitate a slidable and rotatable connection. The idler 423 can be biased outward (or away from the material roll 114) to facilitate engagement with the bracket 18b.
The diverter shaft assembly 426 includes a hollow shaft 450 (or diverter tube or tube) coupled to opposing end caps 454a, b. The end caps 454a, 454b are removably received by the hollow shaft 450. The end caps 454a, 454b can be biased outward (or away from the hollow shaft 450) to facilitate engagement with the brackets 18a, 18b. In this embodiment, the diverter hollow shaft 450 is generally larger in diameter than the hollow shaft 150 (shown in FIG. 1) to decrease shaft deflection. However, due to the increase in diameter of the diverter hollow shaft 450, the diverter 422 includes keyholes 466a, 466b that are configured to couple the diverter shaft assembly 426 to the bracket 18. With reference to FIG. 14, the end cap 454a is configured to be received by one of the first keyhole 466a or second keyhole 466b. The keyholes 466a, 466b are positioned in the diverter 422 to eliminate interference between the diverter shaft assembly 426 and the continuous loop operator (not shown) received by the diverter 422. The end cap 454b is configured to be received by an associated aperture 468a, 468b in the second bracket 18b.
The diverter 422 includes the slot 78 and a non-linear opening 482. The slot 78 is at least partially formed by a first flange 486 and a second flange 490. The first flange 486 includes a first curved edge 494 and the second flange 490 includes a second curved edge 498. The two curved edges 494, 498 are spaced apart to define the non-linear opening 482. The non-linear opening 482 is an angled geometry and is configured to receive the chain 126 (or continuous loop operated 126) as described above in association with the opening 82.
