The present disclosure relates generally to the field of architectural structure coverings, and relates more particularly to a battery pack for use in a motorized architectural structure covering.
Architectural structure coverings may selectively cover a window, a doorway, a skylight, a hallway, a portion of a wall, etc. Generally speaking, horizontal architectural structure coverings may come in a variety of configurations. One type of architectural structure covering may include a motorized controller to lower or raise a covering portion. For example, a motorized drive motor (e.g., an electric motor) can be provided to move the covering portion between an extended position, and a retracted position.
Many known motorized drive motors require power, such as 120 volts, etc., from the facility in which the motorized architectural structure covering is installed to power the motor and control electronics. More recently, battery-powered architectural structure coverings have been introduced. The batteries for these architectural structure coverings can be mounted within, above, or adjacent to the mounting bracket, headrail, fascia, etc. The architectural structure covering may further include brackets for coupling the battery to the architectural structure covering. Unfortunately, these battery-powered systems suffer from many drawbacks, including, for example, requiring the end user to access the battery pack to replace the batteries.
This drawback is compounded by the fact that the battery pack is often coupled to the architectural structure covering behind the headrail associated with the architectural structure covering, and optionally also behind the covering portion, so that the battery pack is concealed. Alternatively, the battery pack may be coupled to the inside surface of the headrail. By concealing the battery pack behind the headrail, and optionally behind the covering portion as well, accessing and removing the battery pack is rendered more difficult, especially since it takes more power to raise the covering portion than lowering the covering portion, which tends to result in the battery pack being more likely to fail when the covering portion is in the extended position, thus requiring the user to reach behind the extended covering portion and the headrail to access the battery pack.
Accordingly, there is need for an improved battery pack wherein the battery pack and the associated batteries located therein are more easily accessible. It is with respect to these and other considerations that the present improvements may be useful.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended as an aid in determining the scope of the claimed subject matter.
Disclosed herein is an improved battery pack for use with a motorized architectural structure covering. The battery pack may include a battery tube having a first end, a second end, and an internal cavity arranged and configured to receive a plurality of batteries therein. The battery pack may also include a first end cap coupled to the first end of the battery tube, and a second end cap coupled to the second end of the battery tube, the second end cap being removably coupled to the second end of the battery tube to enable access to the plurality of batteries contained within the battery pack. The second end cap may also include one or more projections extending from an outer surface thereof for facilitating removal of the battery pack. By incorporating the one or more projections, the user can more easily access, and contact, catch, or latch onto the battery pack, thus pivoting the battery pack downwards for disengaging the battery pack from, for example, one or more mounting clips associated with the motorized architectural structure covering.
In one example embodiment, the battery tube may include first and second cavities interconnected via an intermediate valley portion. The valley portion being narrower than the first and second cavities. The first cavity being configured to receive a first row of batteries while the second cavity may be configured to receive a second row of batteries. The second end cap including first and second release buttons for releasing the second end cap from the second end of the battery tube. The first and second release buttons preferably include a wider portion adjacent the second end cap and a narrower portion at least partially extending into valley portion of the battery tube in-between the first and second cavities. The release buttons preferably are configured to have a larger surface area for contacting by the user without increasing the cross-sectional area or profile of the battery tube, thus contributing to the streamlined profile of the battery pack. By maximizing the surface area, the user is more readily able to contact and press the first and second release buttons, making it easier to remove the second end cap from the battery tube and thus easier to access the batteries located within the battery tube when they need replacement.
The inner sides of the first and second end caps may be configured to create equal length chambers so that the removable second end cap is agnostic with respect to orientation and thus may be inserted into the battery tube in any orientation.
Embodiments of a battery pack for use in an architectural structure covering in accordance with the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the present disclosure are presented. The battery pack of the present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will convey certain example aspects of the covering to those skilled in the art. In the drawings, like numbers refer to like elements throughout unless otherwise noted.
The improved battery pack is adapted and configured to be used with a motorized architectural structure covering. The battery pack may include a battery tube for receiving one or more batteries therein. The battery pack may also include a first end cap coupled to a first end of the battery tube, and a second end cap coupled to a second end of the battery tube. The second end cap is preferably removably coupled to the second end of the battery tube to enable access to the plurality of batteries contained within the battery pack. The second end cap preferably includes one or more projections extending from an outer surface thereof for facilitating removal of the battery pack. In one example embodiment, the one or more projections may be in the form of first and second tabs to facilitate removal of the battery pack from one or more mounting clips associated with the motorized architectural structure covering. The first and second tabs preferably do not protrude beyond the transverse cross-sectional area of the second end cap, thus contributing to the battery pack having a slim profile. In another embodiment, the one or more projections may be in the form of an extension handle extending from an outer surface of said second end cap. The extension handle including an arcuate curvature so that, in use, the extension handle projects laterally away from and downward from the second end cap.
In one example embodiment, the battery tube preferably includes first and second cavities for receiving first and second rows of batteries, respectively. The first and second cavities being interconnected via an intermediate valley portion. The valley portion is preferably narrower than the first and second cavities. Meanwhile, the second end cap preferably includes first and second release buttons for releasably engaging the battery tube. The first and second release buttons preferably include a wider portion adjacent to the second end cap, and a narrower portion extending at least partially into the valley portion of the battery tube. The first and second release buttons preferably have a shape chosen from one of a triangular shape, or a trapezoidal shape, and may be inwardly tapered from top and bottom surfaces of the second end cap to facilitate easier manipulation for removing the second end cap from the battery tube to access the plurality of batteries located therein.
In addition, the first end cap may include a first spring for contacting and biasing the first row of batteries and a second spring for contacting and biasing the second row of batteries. The second end cap may further include an electrically conductive member arranged and configured to contact the first and second rows of batteries. For example, the second end cap may include first and second springs for contacting and biasing the first and second row of batteries, respectively. The first and second springs of the first end cap and the first and second springs of the second end cap both preferably extend an equal distance from the first and second end caps, respectively, so that the first and second cavities have substantially equal length chambers. In this manner, the second end cap is agnostic with respect to orientation and thus may be inserted into the battery tube in any orientation.
The battery pack of the present disclosure may be used in connection with any motorized architectural structure covering. For example, referring to
The architectural structure covering assembly 100 may also include a rotating member 110 (e.g., a roller tube for a roller shade or a lift rod for a stackable shade), and a covering 120. In the illustrated example, the covering 120 has an upper edge 122 mounted to the rotating member 110 and a lower, free edge 124. As will be readily appreciated by one of ordinary skill in the art, the covering 120 of the architectural structure covering 100 may be configured to be vertically extended and retracted relative to the head rail 102 between an extended position (shown in

The first and second cavities 218, 220 are preferably configured to create substantially equal length chambers. This may be accomplished by any mechanism. As shown in
As shown in
Moreover, referring to
The first and second springs 246, 248 may be coupled to the first end cap 240 by any means now known or hereafter developed. As shown, in one example embodiment, the first spring 246 may be molded into the first end cap 240 while the second spring 248 may be removably coupled to the first end cap 240 such as, for example, by extending around a projection or hook 250 formed on the first end cap 240. It will be appreciated that these are examples of connection arrangements, and that others can be used.
Referring to
The second end cap 260 may be removably couplable to the second end 214 of the battery tube 210 by any mechanism now known or hereafter developed. As shown, the second end cap 260 may include first and second release buttons 270, 272. The first and second release buttons 270, 272 may include first and second engaging members 274, 276, respectively, for engaging correspondingly shaped recesses 215 formed in the battery tube 210 adjacent the second end 214 thereof. For example, the first and second engaging members 274, 276 may be in the form of first and second hooks for engaging recesses 215 formed in the battery tube 210.
The first and second release buttons 270, 272 may extend from top and bottom surfaces 262, 264 of the second end cap 260. Preferably, the first and second release buttons 270, 272 are arranged and configured so that when the second end cap 260 is coupled to the second end 214 of the battery tube 210, a portion of each of the first and second release buttons 270, 272 is extendible into the valley portion 222 of the battery tube 210, in-between the first and second cavities 218, 220, when the user presses the first and second release buttons 270, 272 toward each other. The first and second release buttons 270, 272 preferably have a shape chosen from one of a triangular shape, or trapezoidal shape. Alternatively, the first and second release buttons 270, 272 can have any other shape including, but not limited, to a square shape, or a rectangular shape. More preferably, the first and second release buttons 270, 272 are inwardly tapered from the top and bottom surfaces 262, 264 of the second end cap 260 toward the first and second engaging members 274, 276. In this manner, the first and second release buttons 270, 272 provide the user with a more ergometric push-button with a larger surface area for contacting the first and second release buttons 270, 272. That is, as shown, the first and second release buttons 270, 272 preferably have a wider portion adjacent to the second end cap 260, and a narrower portion toward the first and second engaging members 274, 276, so that at least a portion of the first and second release buttons 270, 272 can extend at least partially into the valley portion 222 of the battery tube 210 when the release buttons 270, 272 are pressed. In this manner, the release buttons 270, 272 have a larger surface area for contacting by the user without increasing the cross-sectional area or profile of the battery tube 210, thus contributing to the streamlined profile of the battery pack 200. By maximizing this surface area, the user is more readily able to contact and press the first and second release buttons 270, 272, making it easier to remove the second end cap 260 from the battery tube 210 and thus easier to access the batteries 50 located within the battery tube 210 when they need replacement. As will be readily appreciated by one of ordinary skill in the art, pressing the first and second release buttons 270, 272 toward each other causes the first and second engaging members (e.g., hooks) 274, 276 to move inwards away from the outer surface of the battery tube 210 and thus out of engagement with the recesses 215 formed in the battery tube 210, thereby releasing the second end cap 260 from the battery tube 210.
Referring to
In use, the first and second tabs 286 facilitate removal of the battery pack 200, for example, from the mounting clips 132. That is, as previously described and referring to
As previously mentioned in connection with
The end cap portion 380 preferably also includes an extension handle 386 extending from a side surface of an outer, end surface 381 of the end cap portion 380. Alternatively, the extension handle 386 may extend from a portion of the body portion 383 not received within the opening 362 formed in the second end cap 360. In one example embodiment, the extension handle 386 may have an arcuate shape extending laterally outward and away from the body of the end cap portion 380 so that, in use (e.g., when coupled to the battery pack 200 via the second end cap 360), the extension handle 386 projects laterally away from, and downward from, the second end cap 360. In this manner, the extension handle 386 preferably protrudes beyond the transverse cross-sectional area of the second end cap 360, thus facilitating easier access to a user attempting to locate and remove the battery pack 200. As illustrated, in one example embodiment, the extension handle 386 may have an hourglass shape to facilitate grasping by the user. However, it should be understood that the extension handle 386 may have any other shape. In addition, and/or alternatively, the extension handle 386 may include one or more ribs 387 formed on an inner surface of the handle 386. In use, the ribs 387 also facilitate grasping by the user. It should be noted that while the extension handle 386 is illustrated with two ribs 387, the extension handle may include more or less ribs, and that the ribs 387 may be omitted in their entirety. In use, the one or more ribs 387 increase the rigidity of the extension handle 386.
Moreover, as illustrated, the end cap portion 380 may incorporate one or more openings 393 formed therein. It should be noted that while the end cap portion 380 is illustrated with two separate and distinct openings 393, the end cap portion 380 may include more or less openings, and that the openings may be omitted in their entirety.
Referring to
It should be noted, that while the second end cap portion 380 has been described and illustrated as including a single extension handle 386, it is envisioned that the second cap portion 380 may include two or more extension handles. In addition, or alternatively, while the extension handle 386 has been described as having an hourglass or arcuate shape so that the extension handle 386 projects laterally away from, and downward from, the second end cap 360, it is envisioned that the extension handle 386 may have any desired shape that will facilitate a user grasping the handle 386. In addition, or alternatively, while the extension handle 386 has been described and illustrated as being integrally formed with the end cap portion 380, the extension handle 386 may be separately formed and coupled to the end cap portion 380 by any means now known or hereafter developed including, for example, an adhesive, fasteners, etc. In addition, or alternatively, while the end cap portion 380 has been described and illustrated as being separately formed with respect to the second end cap 360, the end cap portion 380 may be integrally formed with the second end cap 360.
In use, the extension handle 386 facilitates removal of the battery pack 200, for example, from the mounting clips 132, by allowing a user to grasp the extension handle 386 and pivot the battery pack 200 out of engagement with the mounting clips 132. That is, as previously described and referring to
By utilizing a battery pack 200 according to the present disclosure, the battery pack 200 is more readily removed from the architectural structure covering assembly for replacement. In addition, the second or removable end cap 260 is easier to remove than prior end caps, and the second or removable end cap 260 can be coupled to the battery tube 210 in either orientation due to the design of the electrically conductive members.
