MOTORIZED CLOSURE ASSEMBLY

BACKGROUND

The disclosure is directed to motorized closure assembly. Specifically, the disclosure is directed to motorized sliding windows and doors.

Building doors and windows include a number of different types of designs such as overhead doors and windows, horizontal sliding doors and windows, vertical lift doors and windows, folding doors and windows, pocket doors and windows, roller doors and windows etc. With space for buildings and apartments getting increasingly small, so does the space available for any driving mechanisms configured to open and close these doors and windows.

Additionally, safety and aesthetic considerations impose design restrictions making commonly used externally visible and accessible drive mechanisms undesirable.

Accordingly, there is a need for concealed drive mechanisms for doors.

DETAILED DESCRIPTION

The disclosure relates in one embodiment to motorized closure assembly. In another embodiment, the disclosure relates to motorized sliding windows and doors. Accordingly, provided herein are motorized closure assemblies, comprising: an opening frame configured to fit around the opening; a substantially rectangular closure slab having a closure slab frame configured to surround the substantially rectangular closure slab and sealingly fit within the opening frame; and a motorized driver, wherein the motorized closure assembly is entirely embedded within the closure slab frame or within a combination of the closure slab frame and the opening frame

Detailed embodiments of the present technology are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary, which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of the invention.

The terms “first,” “second,” and the like, herein do not denote any order, quantity, or importance, but rather are used to denote one element from another. The terms “a”, “an” and “the” herein do not denote a limitation of quantity, and are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. The suffix “(s)” as used herein is intended to include both the singular and the plural of the term that it modifies, thereby including one or more of that term (e.g., the film(s) includes one or more films). Reference throughout the specification to “one embodiment”, “another embodiment”, “an embodiment”, and so forth, means that a particular element (e.g., feature, structure, and/or characteristic) described in connection with the embodiment is included in at least one embodiment described herein, and may or may not be present in other embodiments. In addition, it is to be understood that the described elements may be combined in any suitable manner in the various embodiments.

In addition, for the purposes of the present disclosure, directional or positional terms such as “top”, “bottom”, “upper,” “lower,” “side,” “front,” “frontal,” “forward,” “rear,” “rearward,” “back,” “trailing,” “above,” “below,” “left,” “right” “horizontal,” “vertical,” “upward,” “downward,” “outer,” “inner,” “exterior,” “interior,” “intermediate,” etc., are merely used for convenience in describing the various embodiments of the present disclosure.

In an embodiment, provided herein is a motorized closure assembly, comprising: an opening frame configured to fit around the opening; a substantially rectangular closure slab having a closure slab frame configured to surround the substantially rectangular closure slab and sealingly fit within the opening frame; a driver, the driver concealed in a recess behind the opening frame and coupled to a driver pulley; a frame pulley, concealed in a recess behind the opening frame on a side opposite the driver; and a cable having a proximal end and a distal end, disposed between the frame pulley the driver pulley, and operably coupled to the slab frame wherein the driver, the cable, the motor pulley and the frame pulley are concealed regardless of the position of the closure slab in relation to the opening frame, the assembly capable of slidably moving the slab between an open position and a closed position.

As used herein, “concealed” means that the cable, the motor pulley and the slab frame pulley are sufficiently enclosed or embedded within the opening frame and/or the slab frame such that, in the normal and typical use of the motorized closure, the user does not typically come into contact with and/or get entangled in, and/or may observe the cable. Thus, the term “concealed” does not necessarily mean that the cable is completely hidden from view when the motorized closure slab is in use in the closed position. Rather, the cable may be slightly/partially visible, as can be seen in FIG. 12, but it is sufficiently recessed within and covered by the closure slab frame in normal use. the term “embedded” refers to the cable, the driver, the driver pulley, frame pulley or other free pulley described herein, being coupled firmly within a surrounding structure, or enclosed snugly or firmly within a material or structure, for example, the closure slab frame, the pane frame or the opening frame and their combination.

The term “coupled”, including its various forms such as “operably coupling”, “coupling” or “couplable”, refers to and comprises any direct or indirect, structural coupling, connection or attachment, or adaptation or capability for such a direct or indirect structural or operational coupling, connection or attachment, including integrally formed components and components which are coupled via or through another component or by the forming process. Indirect coupling may involve coupling through an intermediary member or adhesive, or abutting and otherwise resting against, whether frictionally or by separate means without any physical connection.

The opening can be substantially rectangular or square. For example, an opening for a door or a window and the like. The substantially rectangular opening can have an aspect ratio with a longitudinal axis that is longer than a traverse axis. The longitudinal axis can be parallel with the closure sliding direction or perpendicular to the sliding direction. The closure slab or panes can have a top and bottom horizontal planes and proximal and distal vertical planes. The vertical distal plane defines the plane closest to the opening frame (in other words, the sill) in the closed position, while the vertical proximal plane defines the planes closest to the opening frame in the open position.

The slab can be opaque or have see-through clarity. “See-through clarity” as used herein refers to an easiness with which a target can be visually recognized through the slab and can be specified by total luminous transmittance and/or parallel luminous transmittance. As used herein, the see-through clarity is described to become lower as the luminous transmittance decreases. “See-through” encompasses any characteristic that allows visual inspection through the slab. Specifically, a viewing window, or the entire slab may be translucent, transparent, or entirely clear. “Translucent” indicates that light can pass through the slab, but the light is diffused. It does not require that a whole surface or an article itself is transparent and portions of the article may be transparent or opaque, for example to serve a function or to form a decorative pattern. The term “translucent” as used herein can refer to a slab composition that transmits at least 60% of electromagnetic radiation in the region ranging from 250 nm to 700 nm with a haze of less than 40%. The slab composition can also have a transmission of at least 75% for example, specifically at least 85%. Additionally, the slab composition can have a haze of less than 40% for example, specifically, a haze of less than 10%, more specifically a haze of less than 5%. The term “translucent” can also refer to a composition capable of at least about 40% transmission of light. The light referred to can be, e.g., actinic light (e.g., from a laser), emitted light (e.g., from a fluorochrome), or both, or transmittance of at least 80%, more preferably at least 85%, and even more preferably at least 90%, as measured spectrophotometrically using water as a standard (100% transmittance) at 690 nm. Likewise, “transparent” refers to a slab composition capable of at least 70% transmission of light.

The opening can be in a wall or defined between structural beams. The opening frame can be coupled to the opening, defining an opening frame, or a sill. For example, the opening frame can be comprised of a horizontal upper support beam, a lower horizontal guide rail and two vertical posts (in other words, jambs). The horizontal upper support beam can be coupled to the opening upper boundary, or to a ceiling beam and the like. The lower horizontal guide rail can be coupled to the floor.

The opening frame, and/or the closure slab frame (in other words, the slab frame and/or the frame surrounding the panes) can be made of the same or different material and can be any appropriate material, for example resin (thermoplastic or thermoset), or wood, or metal, or, for example aluminum or a combination comprising at least one of the foregoing, and/or their composites. Methods of forming the frame or parts thereof can be through extrusion molding, injection molding, thermoforming and the like. Likewise, the opening frame used in motorized closures described can be configured to accommodate a single slab or a plurality of slabs, or panes (slabs and panes are used interchangeably in an embodiment). Also, the closure slab (in other words, a window or a door without the attached frame), can be surrounded by a closure slab or closure pane frame that is configured to receive the motorized driver assemblies described herein. A sliding window, door or the like, as described herein can have at least two panes which extend in a generally vertical plane and at least one of which is movable generally horizontally, an opening frame (in other words, a sill) can include a channel that extends generally horizontally and within which bottom horizontal edge portions of each of the at least two panes are received, a dividing member within the channel which extends between the at least two panes, the dividing member extending either in contact with or in close facing relationship with the bottom edge portions of the at least two panes. The bottom of the channel in the opening frame can further include a rail extending generally horizontally and within which bottom edge portions of each of the at least two panes are engaged and slide upon. In another example, the pane frame can include a complementary channel configured to receive the rail. The pane can for example be an inner pane or an outer pane, referring to the relative position of the panes to the interior of the structure.

The slab or combination of panes, can seal the opening when in the closed position. The term “sealingly” as used herein is to be interpreted as substantially impeding airflow, moisture, particulates and the like though the junction and or opening.

The term “pane” is used principally to embody a glass sheet, which may or may not be a framed sheet. However, the term “pane” is not restricted to glass sheet and may for example include any transparent or opaque material, such as polycarbonate (transparent) or timber (opaque). The term is also intended to encompass double glazed units of two or more sheets of glass or other suitable material. In an embodiment, not all panes are motorized. For example, a closure opening can be closed with three panes have three independent pane frames wherein, only the external and mid panes are motorized with the assemblies, while the internal pane is not motorized. Closure slabs, or panes, motorized with the assemblies described herein can have a weight of up to 400 Kg, for example, between 5.0 Kg to 400 Kg, or 5.0 Kg to 300 Kg, specifically, between 5.0 Kg to 250 Kg, or between 120 Kg and 250 Kg, more specifically between 75 Kg and 200 Kg or between 100 Kg to 220 Kg.

The motorized driver used for sliding the panes along the path in the disclosure provided, can be a DC motor (direct current) or an AC motor (alternating current). The driver (in other words, a mechanical power transfer device) can also be a servo motor, an electric motor, a pneumatic motor and/or any other suitable electrical, mechanical, magnetic or other motor or driver that can apply a torque force upon a drive shaft operably coupled to the motor pulley. The driver can be configured to turn in two directions, namely clock-wise and counter-clockwise. The driver can be coupled to a motor pulley through a shaft. In addition, the mechanical power transfer device can further comprise: a gear box, a clutch (electromagnetic, mechanical, pneumatic or other suitable clutch mechanisms), drive shaft, brackets, and other components capable of assisting in power transfer from a motor to the driver pulley.

A frame pulley can be concealed in a recess behind the opening frame (e.g., the sill's vertical member horizontally opposite the driver pulley, for example, behind the jamb) and can be a part of an assembly comprising a base, a top flange and a shaft with the frame pulley being operably coupled to a ball bearing array disposed between the frame pulley and the top flange and between the frame pulley and the frame pulley base. The base can be coupled to a member disposed outside the opening frame, such that, for example, the shaft of the pulley is in parallel with the slab. The opening frame defines an orifice located in front of the frame pulley, allowing for communication between the cable and the frame pulley. The frame pulley can be disposed for example, at the top or bottom of the opening frame and be aligned with the slab or when a plurality of panes is used, be aligned with each pane. Alternatively, the frame pulley assembly can be embedded (in other words encased in, covered by, and/or enclosed) entirely within the closure slab frame or the pane frame.

A cable, having a proximal end and a distal end can be coupled at the cable's proximal end to the proximal bottom horizontal side of the slab or pane frame, meaning the side closest to the driver, through a first tension modulator, which can comprise a coupling bracket, a biasing element and a modulating screw capable of modulating the tension on the cable. The cable can loop around the driver pulley (e.g. to minimize slip), extend through an orifice in the opening frame, disposed in front of the driver pulley, wrap around the frame pulley and operably couple at the cable's distal end to the slab or pane frame, via a second tension modulator assembly. Modulating the tension on the cable can be used, for example, to prevent slip of the cable on the driver pulley.

The term “looped” means a path along which the cable moves, transit or extends in a cyclic and repetitive fashion, and wherein at least two points on the cable may be designated as occupying the same point or position (on or along the guide path, or along an axis perpendicular to the cable). In addition, the looped path (or track) may be further described as being a closed loop path. Furthermore, “looped” or similar used in the description does not only refer to a perfect circular ring shape, but rather is a general term which encompasses an elliptical ring, a square ring, a polygonal ring shape or the like, to indicate any shape of an object defining a preferable closed region. In addition, the term “wrapped” as used herein, refers to circumstances where the cable is wound around a portion of the circumference of the pulley that is less than the whole circumference.

The slab or panes can be slidably coupled to the opening frame (or, in other words the sill). The driver can be configured to slidably move the panes or slab along the appropriate track on the opening frame (in other words, the sill) at speeds of, for example, between 5.0 to 100 cm/sec., specifically, between 5.0 to 60 cm/sec., or between 5.0 to 30 cm/sec., more specifically, between 5.0 to 25 cm/sec., or between 5.0 to 15 cm/sec. The term “slidably coupled” is used in its broadest sense to refer to elements which are coupled in a way that permits one element to slide or translate with respect to another element.

Likewise, the distal and proximal tension modulators described herein can impart a normal operating static load on the tensioned cable that could be, for example, between about 1.0 Kg to 100 Kg, specifically, between about 2.0 Kg to 60.0 Kg, more specifically, between about 4.0 Kg to 12.0 Kg, for example, 5 Kg for motorized closure assemblies and systems involving cables (outside diameter (od) of 1-4 mm). The normal operating static load imparted by the tension modulators used in the assemblies described herein, can be configured to create a static friction that will not be exceeded during normal operation of the drivers and pulleys provided, thus ensuring no slip will occur between the cable and the pulleys. The ability to modulate the tension using the tension modulators described herein, on the cable, can be beneficial to ensure no slip occurs between the cable and pulleys, as well as to dampen the stress on the cable and the motor's drive shaft following initiation of motion upon receipt of the proper command from a command and control module (CCM) in electronic communication with the driver. Initiation of motion in any of the motorized closure assemblies can be done once the CCM has verified that any locking means are disengaged. For example, a locking means comprising a pin wherein the pin is electromagnetically actuated between a recessed position within the closure slab or pane frame and an open position protruding outside of the closure slab or pane frame, and inserted into the opening frame and/or an adjacent pane frame, can be actuated by the CCM. Prior to initiation of motion of the motorized closure assemblies described, the CCM verifies that the locking pin is in the recessed position, if the pin is in the recessed position, then the motion of the closure slab or pane using the assemblies described herein will be initiated. Else, the pin can be recessed and motion initiated or an alert can be provided to the user.

In an embodiment, provided herein is a drivetrain for a motorized closure assembly, comprising: a leveling assemble; and a mobilizing assembly, wherein the mobilizing assembly comprises: a driver; a clutch; a gear box; and a track wheel coupled to the gear box, the track wheel configured to engage a rail. The rail can be disposed, for example, within a channel in the horizontal frame base, configured to receive the closure slab frame or pane frame, extending the length of the channel.

The motorized closure assembly, comprising: an opening frame configured to fit around the opening; a substantially rectangular closure slab having a closure slab frame configured to surround the closure slab and sealingly fit within the opening frame can comprise a first drivetrain embedded within and operably coupled to the closure slab frame or pane frame. The leveling assembly can comprise an adjustment screw, threaded through an adjustment screw bracket coupled to attachments means configured to couple the leveling assembly to the closure slab frame or the pane frame. The tip of the adjustment screw opposite the screw head can be configured to have channels extending perpendicular to the longitudinal axis of the adjustment screw, configured to slidably couple in a groove defined in the posterior end of a leveling assembly. The leveling assembly can have a beveled anterior end (in other words, creating a wedge), configured to slidably couple to an oppositely slanted mobilizing assembly posterior end, such that turning the adjustment screw will cause the leveling assembly to slide between a bottom surface of the closure slab frame or the pane frame, and the mobilizing assembly, causing the closure slab frame or the pane frame to lift in relation to the rail. The mobilizing assembly can be hingedly coupled to the closure slab frame or the pane frame at the anterior end. The motorized systems described herein can have a first and a second drivetrains embedded within and operably coupled to the closure slab frame or the pane frame.

The first and second drivetrain can comprise a driver; a clutch; a gear box, a track wheel the track wheel configured to engage a rail on the closure frame (or in other words, the sill). The gearbox can comprises, for example, a beveled gear; and at least one spur gear, wherein the at least one spur gear is operably coupled to the track wheel, the track wheel configured to engage a rail on the opening frame. The gear assembly (or gear box) can also include the elements such as shown in FIGS. 16-18 and/or can include any other suitable gears, pulleys, belts, chains and/or any other drive element know to those skilled in the art of power transmission, such as to transfer driving forces from a driver to a driven element (for example, the track wheel. The term “drivetrain” is used in its broadest sense to refer to the combination comprising the leveling assembly, the adjustment screw, the adjustment screw bracket and frame coupling means, the driver motor, the driveshaft, the transmission assembly, the clutch, the housing and the slab attachment means and the track wheel. However, other elements, such as the bottom part of the slab or pane frame can be a part of the drivetrain. In a specific example, the number and location of the drivetrain can be varied and be between 1 and 4 drivetrain assemblies, located for example, along the bottom horizontal plane of the closure slab or closure pane or at the top plane of the closure slab or closure pane. Upon receipt of a command from a command and control module (CCM), in electronic communication with the drivetrain(s), when, for example, two drivetrain assemblies are coupled to the closure slab frame or closure pane frame, movement of the first drivetrain in one direction can be initiated.

Upon power failure or selection by a user on the CCM, the clutch, for example, an electromagnetic clutch can disengage the driver motor from the gear box, allowing for manual opening or closing of the slab or pane. It would be recognized that a similar clutch can be disposed between the drive shaft of the driver motor and the driver pulley described in the assemblies provided throughout this disclosure, enabling the same operations.

The drivetrain assembly can be located at the top plane of the pane closure, moving the track wheel along a shelf in the opening frame such that the track wheel and the gear assembly hangs on the rail attached on the shelf in the sill. The drivetrain can further comprise coupling means to operably couple the drivetrain to the closure slab or pane frame. The coupling means can comprise hinges, attachment members and the like, which may be used to attach the drivetrain to the frame of the closure slab or pane. In a specific example, a pane frame having a profile that can be configured retroactively to receive the drivetrain disclosed herein is provided with a drivetrain as described herein, thereby enabling the pane to move upon receipt of a command from a control module.

In another embodiment, provided herein is a motorized closure assembly, comprising: an opening frame configured to fit around at least the top horizontal side, a distal vertical side, and a bottom horizontal side of a substantially rectangular opening; a substantially rectangular closure slab having a closure slab frame configured to surround the substantially rectangular closure slab and sealingly fit within the opening frame; a driver, the driver embedded within a proximal (e.g., to the drive motor) vertical side of the substantially rectangular closure slab frame and coupled to a driver pulley; a frame pulley, can be embedded within and coupled to a distal horizontal side of the substantially rectangular closure slab on a horizontal side opposite the driver pulley. The driver pulley and the frame pulley can be disposed such that both are on the same level, while the driver body extends above the driver pulley. A first free pulley can be disposed between the driver pulley and the frame pulley and operably coupled to the closure slab frame. Depending on the span of the bottom horizontal side of the closure slab frame or the pane frame, and/or the weight of the closure slab frame or the pane frame, more than one free pulleys can be employed. In addition, a cable can connect the motor pulley, the first free pulley and the frame pulley, wherein the cable and the free pulley are embedded within the closure slab frame (e.g., the lower horizontal side of the closure slab frame or the pane frame).

Pocket door systems have become an increasingly preferred door system in the construction of residential and commercial building structures in which room space is limited. The pocket door system can include a header assembly having a track on which trolley assemblies are slidably coupled for translational movement. A door can be suspended from the trolley assemblies and is, therefore, capable of movement between a closed position and an open position wherein, in the open position, the door can be concealed within a pocket formed in the surrounding wall structure. Such a door system offers the advantage over standard hinged door arrangements in that dedication of floor space is not required to open the door from a closed position. The motorized closure assemblies described herein can be used for example to impart motion to pocket doors.

The first free pulley can be operably coupled to the closure pane or closure slab frame via a bracket, the bracket can be coupled to the frame directly and be configured not to interfere with the sliding motion of the closure slab or pane. The first bracket can be operably coupled to the first free pulley, and the first free pulley can be positioned in parallel with the closure slab. Likewise, the first bracket can be operably coupled to the first free pulley, where the first free pulley can be positioned in parallel with the closure slab at an anterior side of the bracket and coaxially coupled to a first track wheel. Also, the second free pulley can be operably coupled to the closure pane or closure slab frame via a bracket. The second bracket can be operably coupled to the first free pulley, where the first free pulley can be positioned in parallel with the closure slab at an anterior side of the bracket, and coaxially coupled to a second track wheel. The first and second track wheel can be configured to engage and rollingly travel along a rail dispose within a channel defined by the horizontal bottom, or base of opening frame.

The cable can be a closed loop, looping around the driver pulley (e.g., the motor pulley) and the first free pulley and optionally the second free pulley, while wrapping around the frame pulley. The frame pulley can be coupled to the closure slab or closure pane frame via an assembly, which in turn can comprise a tension modulator.

Upon receipt of command from the CCM, the driver can be activated to turn the driver pulley (e.g., the motor pulley) either clockwise or counterclockwise turning the driver pulley in a corresponding direction, causing the cable to rotate the first free pulley, coupled to the closure slab or closure pane frame, rotate the track wheel, thereby causing the slab or pane to slidably move from an open to closed position or from a closed to an open position. In a specific example, the cable can loop around at least a second free pulley as described herein. The skilled artisan will recognize, that the number of free pulleys used in the motorized closures described herein, can depend on, for example, the span of the opening, the weight of the closure slab, the size of the driver, the available packaging space within the closure slab frame, or a combination comprising at least one of the foregoing.

The cable can be made of any material appropriate for the necessary tension. The use of cable described indicates that the cable be able to survive high tensile loading. The closing and opening motion of the closures described may require that the umbilical or tether cable provide for the bi-directional motion. It may be beneficial to have innate low elongation characteristics, preventing the fibers of the cable from stretching, hence the need for low elongation, high tensile strength fibers. The cable can, for example be a high strength stainless or galvanized steel rope for that purpose. Alternatively, the cable can be made of Kevlar (in other words, a para-aramid synthetic fiber) or Vectran (an aromatic polyester produced by the polycondensation of 4-hydroxybenzoic acid and 6-hydroxynaphthalene-2-carboxylic acid), or Technora (condensation polymerization of terephthaloyl chloride (TCl) with a mixture of p-phenylenediamine (PPD) and 3,4′-diaminodiphenylether (3,4′-ODA)) and the like ropes and braided fibers having an elongation of no more than 10%. With proper placement in the cable and suitable termination or anchoring techniques the rope can provide a dual role. The cable diameter can be between 1 and 5 millimeter for example, having a breaking strength of between 50 and 1000 Kg, and can be sheathed (in other words jacketed) in a resin to increase the friction between the cable and the driver pulley and the frame pulley.
