DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0032] As can be appreciated from FIGS. 1-10, embodiments of the window covering can include a height adjustment mechanism for controlling the raising and lowering of window covering material that permits the window covering material to be raised and lowered without use of lift cords passing through a cord lock and/or without use of any lift cords. In some embodiments, the window covering can be configured as a roll-up shade.

[0033] For instance, the window covering 1 can have window covering material 2 that extends from a first rail 3. A top portion of the window covering material may be connected to the first rail. A bottom portion of the window covering material 2 may be connected to a second rail 4.

[0034] The first rail 3 may be a headrail or the intermediate rail of a top down bottom up shade. The second rail 4 may be a bottom rail. In some embodiments, it is contemplated that the second rail 4 may not be present.

[0035] The window covering material 2 can be moveable from a first position to a second position and may also be moveable to a number of other positions that may be located between the first and second positions. For instance, the window covering material 2 can be configured to be moveable between a fully extended position or a fully lowered position to a fully retracted position or a fully raised position and may also be moved to other positioned between the fully lowered and fully raised positions.

[0036] The window covering material 2 can be composed of any number of suitable materials, such as fabric, woven wood, woven bamboo, woven together polymeric slats (e.g. polyvinyl chloride (“PVC”) slats, etc.), or other type of window covering material. The width W of the window covering material may extend from a first side of the window covering material to a second opposite side of the window covering material. The first and second sides may extend along the length L of the window covering material from a top of the window covering material located adjacent the first rail 3 to a bottom of the window covering material located adjacent the second rail 4. The first rail 3 can be structured as a shaft, tube, bar, or other elongated member composed of metal, polymeric material, wood, or other type of material. The second rail 4 can also be structured as a shaft, tube, bar, or other type of elongated member composed of metal, polymeric material, wood, or other type of material.

[0037] The window covering material 2 can include a first portion 2a, a second portion 2b, and a third portion 2c. The third portion 2c may be located adjacent the first rail, the second portion 2b can be positioned between the first and third portions 2a and 2c. The first portion 2a can be the bottom portion of the window covering material. The window covering material 2 can be coupled to the first rail 3 such that when the window covering material 2 is raised, the first portion 2a of the window covering material rolls up about the second rail 4 or about the bottom of the window covering material. The second portion 2b can also be rolled up as the window covering material is moved from its fully extended position to a retracted position. The third portion 2c may be located above the rolled up portion as the window covering material is rolled up during raising of the window covering material. When the window covering material 2 is lowed, the second portion 2b and/or first portion 2a may be unrolled. In some partially extended or partially retracted positions of the window covering material 2, the first portion 2a may be rolled up while the second portion 2b and the third portion 2c is unrolled and located above the rolled up portion of the window covering material. Some embodiments may be configured so that when the window covering material is in a fully extended position, the first portion 2a may be unrolled. Other embodiments can be configured so that when the window covering material is at a fully extended position the first portion 2a may still be in a rolled up position.

[0038] The window covering material 2 can include a plurality of elongated members 11 that extend from the top of the window covering material 2 adjacent the first rail 3 to the bottom of the window covering material adjacent the second rail 4. The elongated members may be flexible members such as cords, polymeric filaments, or other types of elongated flexible elements. The elongated members 11 can include spaced apart connects 11a, such as loops, rings, or other type of connectors. The connectors 11a can be coupled to the elongated members to form columns of connectors along the length L of the window covering material 2. The connectors 11a in each of the columns may be spaced apart from the other connectors in that column along the length L of the window covering material. Connectors 11a in one column of connectors 11a can be positioned to be parallel to corresponding connectors 11a of other columns of connectors 11a. For instance, a first column of spaced apart connectors 11a can be located adjacent the first side of the window covering material 2 and a second column of spaced apart connectors can be located adjacent the second side of the window covering material 2. Connectors of the first column can be positioned so that each connector 11a is at a location along the length L of the window covering material that is aligned with a corresponding connector 11a of the second column of connectors. It is contemplated that there may be other columns of spaced apart connectors 11a attached to other elongated members 11 between the first and second columns located adjacent the first and second sides of the window covering material 2.

[0039] The second rail 4 can include a spring arrangement, such as a roller spring arrangement, a coil spring arrangement that is coupled to a clutch 33 within a channel or cavity of the second rail, or another type of spring arrangement that is configured to bias the second rail 4 to rotate to facilitate rolling up of the window covering material during raising of the window covering material 2. The spring arrangement of the second rail 4 can be configured so that it is adjustable from an engaged position to a disengaged position via clutch or other mechanism so that a biasing force of the spring is only translated to effect rotation of the second rail when it is adjusted to its engaged position. When adjusted to its disengaged position, the spring 30 can be prevented from transferring its biasing force to drive rotation of the second rail 4 for winding or rolling up of the window covering material 2. At least one handle can be connected to the second rail 4 and to the clutch so that motion of the handle actuates motion of the clutch to adjust the clutch 33 to actuate adjustment of the spring between its engaged and disengaged positions. Alternatively, no handle may be needed and a user may just manipulate a bottom portion of the window covering material or the rolled up portion of the material to manipulate the second rail 4 to actuate adjustment of the clutch 33 and the spring 30. For instance, a user can manipulate the bottom portion of window covering material 2 to provide a force for adjusting the clutch 33 to actuate adjustment of the spring 30 between its engaged and disengaged positions by causing the second rail 4 to rotate in a first rotational direction or a second rotational direction to cause the clutch to adjust its position.

[0040] In some embodiments, the second rail 4 can be connected to at least one handle 5. For embodiments in which only a single handle 5 is utilized, the handle 5 can be configured to include an elongated member 5e that extends along the width W of the window covering material and is spaced apart from the window covering material such that a gap can be presented between the handle 5 and the rolled up portion of window covering material that is present during raising of the window covering material 2. Opposite first and second ends 5c and 5d of that single handle can be attached to the opposite ends of the second rail 4. At least one end of the single handle may be directly connected to a clutch 33 within the second rail to provide a rotatable and/or linearly moveable connected to a clutch 33 for actuating adjustment of a position of the clutch to adjust the position of the spring between the spring's engaged and disengaged positions.

[0041] In other embodiments, there may be a first handle 5a connected to a first end of the second rail 4 and a second handle 5b connected to a second end of the second rail 4 that is opposite the first end of the second rail 4. For instance, each handle may extend from the side of the second rail to which it is attached as shown in FIGS. 5-6 and 10. The handles can be sized to make the handles less visible. For embodiments of the window covering that may utilize a spring 30 coupled to a clutch 31 within the second rail 4, the handles may be positioned to help a user provide a force for actuating adjustment of the position of the clutch 31 for actuating adjustment of the spring 30 between its engaged and disengaged positions while not substantively detracting from the aesthetic effect provided by the window covering material.

[0042] Each handle can be coupled to the second rail 4 so that it is rotatable and/or linearly moveable relative to the second rail 4 at the opposite ends of the second rail. The motion of the handle 5 can be configured to actuate adjustment of the spring between its engaged and disengaged positions via a clutch or lock mechanism connected between the handle and the spring. For instance, sliding the handle 5 upwards from a lowermost position to an upper position via linearly moveable connections the handle's opposite ends have to the opposite ends of the second rail 4 can be configured to adjust the spring 30 from its disengaged position to its engaged position. As another example, rotating the handle 5 in a first rotational direction (e.g. clockwise or counterclockwise) via rotatable moveable connections the handle's opposite ends have to the opposite ends of the second rail 4 can be configured to adjust the spring from its disengaged position to its engaged position. A user may use the handle 5 to translate an upward force to adjust the window covering material to raise that material and the activation of the spring can result in effecting a rolling up of the window covering material as the window covering material is raised, or retracted, via motion of the handle in an upwards direction. A user can rotate the handle in an opposite second rotational direction (e.g. a direction that is opposite the first rotational direction) to adjust the handle to its initial first position to cause the spring to adjust to its disengaged position and/or to provide a force for lowering the window covering material to a more extended position such that window covering material unrolls from the rolled up portion as the material is extended, or lowered.

[0043] When the user has selected a desired position for the window covering material 2, the user may use clips 7 or another mechanism for maintaining the height of the window covering material at its selected position. For example, a position of the window covering material can be maintained by use of clips 7 that can be attached to the second rail 4 by having the hook ends of the clip connected to or moved into engagement with connectors 11a. The clips' connection of the second rail 4 to the window covering material 2 via connectors 11a can maintain the position of the second rail 4 and rolled up portion of the window covering material at a desired location. To re-adjust the position of the window covering material, the hook ends of the clips may be decoupled from the connectors 11a and the handle 5 may be grasped by a user to provide a force for raising or lowering of the window covering material as previously described herein. Once at its new position, the hook ends of the clips 7 can be recoupled to different connectors 11a for maintaining the window covering at the new position.

[0044] Instead of utilizing clips 7, at least one handle 5 can be configured for motion to engage the rolled up portion of the window covering material to lock the window covering material in place to keep that material at its selected position. For instance, the handle 5 can be rotated or slideably moved to its lowermost position, or its first position, so its intermediate portion that extends along the width W of the window covering material contacts the rolled up portion of window covering material to engage that material and provide sufficient friction to prevent the rolled up material from unrolling to maintain the position of the window covering material 2. In some embodiments, the entire intermediate portion of the handle can extend along the width W of the window covering material to contact the rolled up portion of the window covering material adjacent to the unrolled portion above the rolled up portion to maintain the position of the window covering material 2. In that position, the handle 5 may also contact the unrolled up portion of the window covering material along the width W of the window covering material.

[0045] In other embodiments, it is contemplated that there may be first and second handles 5a and 5b as shown in FIGS. 5-8 and 10 that are moveable between engaged and disengaged positions. When the handles are in their engaged positions, they can engage the window covering material and/or the rolled up portion of the window covering material to maintain the position of the window covering material via direct contact with the window covering material and/or rolled up portion of the window covering material to provide sufficient friction to prevent unrolling of the rolled up portion of the window covering material. When the handles are in their disengaged positions, they may be out of contact with or otherwise disengaged from the rolled up portion of the window covering material to permit the window covering material to be raised or lowered.

[0046] In some embodiments, distal ends of the first and second handles 5a and 5b can be moveable to pass through a respective connector 11a to function as a clip or hook portion to engage the window covering material and maintain the position of the material at a user selected position. For such an embodiment, the distal ends of the handles may also be moveable so they can be moved away from the connectors 11a to disengage the window covering material and facilitate height adjustment of the window covering material.

[0047] The motion of each handle between its engaged and disengaged positions (e.g. lowermost and upper positions) can be via linear and/or rotational motion relative to the second rail 4. Thereafter, a user may provide a force to rotate or linearly move the handle 5 to a higher position, or a second position, to move the elongated middle portion of the handle 5 out of contact with the rolled up portion of the window covering material 2 to permit height adjustment of the window covering material as discussed herein. Once at the newly selected location, the handle 5 may be returned to its first position to help maintain the window covering material at its new location as discussed herein. In some embodiments, the linear motion of each handle can be provided by a telescoping section of each handle or each end of a single handle that is configured to extend and retract via moveable telescoping segments of the handle. In other embodiments, linear motion of the handle can be effected by a slideable connection or an extendable connection between an upper portion of the handle and a lower portion of the handle that is connected to an end of the second rail 4. A rotational connection between an end of the second rail and an end of the handle attached to that end of the second rail can also, or alternatively, be provided so that the handle is rotatable in first and second rotational directions.

[0048] For embodiments of the window covering material in which each handle has a rotational attachment to the second rail 4, the handle can be configured to be rotated to extend below the window covering material. The rotation of the handle can also be configured to permit the handle to be more easily grasped or manipulated by a user. A ball and socket type connection, or other type of rotatable connection mechanism may be utilized to provide the rotatability of the handle.

[0049] In some embodiments, the locking of the position of at least one handle in its engaged position may be configured so that the locking is based solely on linear motion of the handle form an extended position to a retracted position. For instance, the handle can be configured so that a significant force from a user that is significantly greater than the force provided by raised shade material being effected by gravity is required to move the handle from its retracted position in which it may engage the window covering material and its extended position in which the handle may be disengaged for the window covering material. Friction between different telescoping segments of the handle may provide this locking feature.

[0050] Alternatively, another type of lock mechanism may be coupled to the handle to lock the handle in its engaged position. In some of these alternative embodiments, the rotational connection of the handle to the second rail may not have a substantial role in locking the position of the handle or ensuring the handle stays in engagement with the rolled up portion of window covering material to maintain a position of the window covering when the handle is in its engaged position. In other embodiments, the lock mechanism may lock the handle to prevent its rotational motion to ensure the handle stays engaged with the window covering material and/or the rolled up portion of the window covering material to lock the position of the handle 5 and maintain the position of the window covering material.

[0051] Referring to FIGS. 7-8, a lock mechanism 41 can be coupled to a handle adjacent its connection to a first end of the second rail 4. In some embodiments, each end of handle 5 may have a lock mechanism 41 attached to that end. In embodiments having spaced apart first and second handles 5a and 5b, a lock mechanism 41 can be attached to each handle. Each locking mechanism can include an actuator 43 that is moveably attached to the handle 5 so that the actuator 43 can move between first and second positions. A connection between the actuator 43 and a locking element of the lock mechanism 41 can be configured so that motion of the actuator 43 to the first position results in the locking element being caused to move to a locked position to adjust the locking mechanism into a locked position and motion of the actuator 43 to a second position can be configured to cause the locking element to move to an unlocked position to adjust the locking mechanism into an unlocked position. The actuator 43 can be a handle, lever, knob, latch, or other graspable element that is configured so that a user may grasp and manipulate the actuator to adjust the position of the actuator between its first and second positions for locking and unlocking the lock mechanism 41. The actuator 43 can be connected to a housing 45, which may be configured as a bracket or other element for attachment of the actuator 43 to at least one locking element of the lock mechanism 41 and/or the second rail 4 for facilitating the movement of the actuator between its first and second positions and adjustment of the lock mechanism between its locked and unlocked positions. The housing 45 can include one or more of the locking elements that are configured to be movable between locked and unlocked positions to engage a component of the handle or connection of the handle to the second rail 4 for locking the position of the handle when the lock mechanism 41 is in the locked position. In other embodiments, the one or more locking elements may extend from the actuator into the handle 5 without being within a separate housing element.

[0052] In some embodiments, the actuator 43 may be rotationally connected to move rotationally between its first and second positions. In other embodiments, the actuator may be linearly moveably connected or otherwise moveably connected to at least one moveable locking element. The motion of the locking element may be linear or rotational as well. In some embodiments, the motion of the locking element may be curvilinear or have another type of motion or path of motion effected via motion of the actuator to which it is connected.

[0053] In some embodiments, the locking element adjusted by motion of the actuator 43 can be an element that interacts with at least one spring coupled to the handle to which it is connected to effect a transfer of force from the spring to the handle for locking the position of the handle when the actuator is moved to its first position to move the locking element into its locked position. The one or more locking elements can also be configured to be moved to another position to prevent the spring from transferring a force to the handle when the locking element is moved to its unlocked position via motion of the actuator 43 to its second position. In other embodiments, the locking element may provide a mechanical interlock between the handle and its connection to the second rail 4 or bottom portion of window covering material to lock the position of the handle when the locking element is moved to its locked position and may be moved out of such an interlock position with the handle to permit the handle to move when the locking element is moved to its unlocked position.

[0054] It should be understood that in embodiments of the window covering that may use a clutch coupled to a spring within the second rail 4 to help facilitate rolling up of the window covering material during raising of the window covering, the one or more handles may be configured so that they do not have to engage the window covering material or use clips or other mechanism to attach to the window covering material for maintaining a position of the window covering material at a user selected position. Instead, the clutch can be configured to provide a strong enough force to hold the rolled up window covering material at the selected position by not permitting rotation of the second rail when the clutch is moved to position the spring in a disengaged position. In other embodiments in which a spring is positioned in the second rail 4, a clutch may not be present. For such configurations, a lock mechanism may be utilized to lock the position of the spring. In yet other embodiments, clips or the moveable handle that is configured to engage the window covering material to maintain a position of the window covering material may be utilized to help ensure the window covering material stays in a user selected position.

[0055] It should be appreciated that embodiments of the window covering and method of making and using the window covering can vary to account for different design objectives. For example, the type of window covering material that is utilized may be any of a desired number of different types of material to provide a desired aesthetic effect and/or a desired insulative property. The material may be sheer, may be light filtering, may be light blocking, or may have other properties as well. As another example, the first rail 3 can be composed of a wood, be an extruded metal rail, or be a polymeric rail and also have any number of different structural shapes and configurations (e.g. an elongated beam, a bar, a rod, etc.). The first rail 3 may have an internal conduit defined therein, may have a channel, or may be a solid structure and have a cross section that is rounded, circular, oval, polygonal, or have another type of shape. In some embodiments, it is contemplated that the first rail 3 may have profiles or connector elements that are configured to receive portions of the clips or a portion of handle 5 so that the handle 5 or clips 7 can be attached to the first rail and extend from the first rail to the rolled up portion of window covering material and/or the second rail 4 when the window covering material is in a fully retracted position, fully raised position, or fully open position. As another example, the second rail 4 can be composed of a wood, be an extruded metal rail, or be a polymeric rail and also have any number of different structural shapes and configurations (e.g. an elongated beam, a bar, a rod, etc.). The second rail 4 may have an internal conduit defined therein, may have a channel, or may be a solid structure and have a cross section that is rounded, circular, oval, polygonal, or have another type of shape. In some embodiments, it is contemplated that the second rail 4 may have profiles or connector elements that are configured to receive portions of the clips or handle so the clips 7 or a portion of handle 5 so that the handle 5 or clips 7 can be attached to the second rail 4 and extend from the second rail 4 to the rolled up portion of window covering material or above that portion of the window covering material when the window covering material is in a fully retracted position, fully raised position, or fully open position (e.g. extend from the second rail 4 to the first rail 3 or from the second rail 4 to a top portion of the window covering material, etc.). The first rail 3 or second rail 4 could have one or more springs coupled therein to help facilitate the raising and/or lowering of window covering material 2. In some embodiments, those one or more springs may be coupled via a clutch or other type of attachment mechanism to permit the one or more springs' ability to provide a biasing force to be engaged and disengaged. Thus, while certain exemplary embodiments of window covering and methods of making and using the same have been shown and described above, it is to be distinctly understood that the invention is not limited thereto but may be otherwise variously embodied and practiced within the scope of the following claims.
