Patent Application
20110156411
The present disclosure relates generally to latching systems, including for panels that may be moved to cover or reveal an opening, for example, to a wall, room, or other area inside or outside of a building.
The standard residential door, which often consists of a wood flush door mounted by three hinges along one side connected to a hinge frame where the door is arranged to swing through an arc, may be the most common type of door, but many additional varieties of moveable barriers have been developed to cover or reveal one or more openings. For example, sliding doors, lift-slide doors, double doors, Dutch doors, French or casement doors, side-light doors, louver doors, bi-fold doors, screen doors, wicket doors, pocket doors, temporary walls and other partitions (and certain combinations of the foregoing) may also be used to provide ingress to and egress from a room or area, and various types of windows may also be used to close or reveal an opening. With such a variety of applications, it is desirable to provide a variety of appropriate latching systems.
For example, lift-slide doors and lift-slide windows have particular design characteristics and popular applications. Lift-slide doors and windows generally include a casement, sash or frame that defines a body of the door or window. From a closed or lowered position, this body generally can be raised relative to its surroundings and then moved side-to-side in a sliding motion. Lift-slide doors can be built to the size of entire walls which makes them popular for applications where a wall may be opened up to the outdoors to provide for “indoor-outdoor living”, such as for sun-rooms, areas with swimming pools, and rooms with a view. Because lift-slide doors may be designed to be stacked flush next to side jambs or in wall pockets when they are opened, latching systems that permanently protrude from such doors may not be desirable. Latching systems that have removeable parts, which require disassembly and storage, may also not be desirable. Given the characteristics and applications of such doors and windows, it is desirable to provide appropriate latching systems.
The present disclosure may be used by one of ordinary skill in the art to provide latching systems that are designed appropriately for their applications. Certain embodiments of latching systems in accordance with the present disclosure may provide one or more advantages, including in relation to their cost of manufacture, simplicity of operation, convenience, aesthetics, durability, compact design, and avoiding unwanted contact, including with other doors, walls, and passing objects and persons.
The above-mentioned drawbacks associated with existing latching systems are addressed by the embodiments of the present application, which will be understood by reading and studying the following specification.
One embodiment of the present application comprises a handle mechanism of a latching system comprising a housing having a recessed channel, a handle base and a handle member. The recessed channel of the housing extends in at least a first direction and a second direction from a lateral mid-plane of the recessed channel. The handle base and handle member are configured to be retracted into the recessed channel.
Another embodiment of the present application comprises a handle mechanism of a latching system comprising a housing having a recessed channel, a handle base and a handle member. The handle base and handle member selectably moveable relative to the housing to define an extended orientation. The handle base and the handle member are selectably moveable to define a first retracted orientation corresponding to an open state of the handle mechanism and a second retracted orientation corresponding to a closed state of the handle mechanism.
According to another embodiment of the present application, the latching system comprises a housing having a recessed channel, a handle base, a handle member and a panel. The housing is coupled to the panel. The handle base and handle member are configured to be disposed in an extended orientation and the handle member is operable for selective rotation about an axis of rotation to control transition between an open state and a closed state of the panel of the latching system.
These and other embodiments of the present application will be discussed more fully in the detailed description. The features, functions, and advantages can be achieved independently in various embodiments of the claimed invention or may be combined in yet other embodiments.

In the second retracted orientation, the coupler 122 engages and holds the bearing transition mechanism 311 in a lifted state such that the bearing elements 312 remain engaged with the track 305 and the bottom portion of the panel 301 remains disengaged from the track 305.
The features and elements of the present disclosure are not, and shall not be, limited to those disclosed and described herein. It is envisioned that the present disclosure may comprise various embodiments and combinations thereof which may be appreciated by or apparent to one of ordinary skill in the art given the benefit of the disclosure. In alternative embodiments, there may be more than one panel, each panel being selectably slidable into at least one pocket frame or into a stacked panel configuration. Further, one or more panels may be of a straight or curved construction.
The various components of the latching system 300 may comprise various suitable materials such as but not limited to, wood, metal, composite wood, metal alloy, plastic, fiberglass, glass, or any combination of the foregoing or other suitable materials.
In some embodiments, one or more tracks 305 may fasten to or seat within a flooring surface. The bearing elements 312 and the head frame 303 may be configured to enable one or more panels 301 to swing or pivot open, as opposed to sliding in a linear or curve-linear direction along a plane or path coincident with the outer frame 302 and pocket frame 304. In an alternative embodiment, there may be one or more tracks 305 mounted to the head frame 303 to further enable guidance of one or more panels 301 which may include one or more bearing components 312 coupled to a top portion thereof
In another embodiment, the one or more panels 301 of the latching system 300 may be motorized such that the lifting and/or sliding motion is performed with little or no user assistance. The motorized operation may be controlled by one or both, a remote control and wall mounted controls.
In operation, the handle assembly 100 may be configured to selectably define multiple positions of extension and retraction as discussed herein. An advantage of the present disclosure is the various possible positions of the handle assembly 100.
In one embodiment, when the handle assembly 100 is in the extended orientation, the handle base 120 is not disposed flush inside the recessed channel 111 but extends at a selectable angle from the housing 110 and the handle member 121 extends at a selectable angle relative to the housing 110. The first joint 123 and second joint 124 are configured to enable the handle base 120 and handle member 121 to be selectably angled and retain positioning in a selected angle. The handle member 121 may be selectably rotated in a first arcuate direction to place the handle assembly 100 in the extended orientation. In an embodiment, when the handle assembly 100 is in the extended orientation, the latch member 307 is disengaged from the latch coupler 306 and the bearing system 310 is actuated so that the panel 301 may traverse the track 305. According to one embodiment, when the handle base 120 and handle member 121 are disposed in an extended position, the handle member 121 is operable for rotation about an axis of rotation to control transition between an open state and a closed state of the panel 301.
In another embodiment, when the handle assembly 100 is in the extended orientation, the handle base 120 is not disposed flush inside the recessed channel 111 but extends at a selectable angle from the housing 110 and the handle member 121 extends at a selectable angle relative to the housing 110. The handle member 121 may be selectably rotated in a second arcuate direction to place the handle assembly 100 in the extended orientation. In another embodiment, the handle member 121 may be selectably rotated in the first arcuate direction to place the handle assembly 100 in the extended orientation. In one embodiment, the magnitude of angular rotation of the handle member 120 defines the operation of the latching system. In another embodiment, the direction of arcuate rotation of the handle member 120 defines the function of the latching system. In one embodiment, when the handle assembly 100 is in the extended orientation the latch member 307 is disengaged from the latch coupler 306, the latch member 307 is retracted into an interior portion of the panel 301, and the bearing system 310 is in an actuated state so that the panel 301 may traverse the track 305. According to one embodiment, when the handle base 120 and handle member 121 are disposed in an extended position, the handle member 121 is operable for rotation about an axis of rotation to control transition between an open state and a closed state of the panel 301.
In an alternative embodiment, positioning the handle base 120 and handle member 121 from a first retracted position to an extended position may cause one or both of the following operations to happen: (a) the latch member 307 to disengage from the latch coupler 306, and (b) the bearing system 310 to actuate so that the panel 301 may traverse the track 305.
In an alternative embodiment, positioning the handle base 120 and handle member 121 from a second retracted position to an extended position may cause the latch member 307 to emerge from a retracted position disposed interior to the panel 301. In an embodiment, positioning the handle base 120 and handle member 121 from an extended position to the second retracted position causes the latch member 307 to retract into an interior portion of the panel 301.
The handle assembly 100 may be oriented in a primary storage position. In an embodiment, when the handle assembly 100 is in the primary storage position, the handle base 120 and handle member 121 are retracted into the recessed channel 111 so as to be flush with a top surface of the rim 114 of the housing 110. In operation, when the handle base 120 and handle member are retracted into the primary storage position (i.e., stored in the recessed channel 111), the panel 301 is able to fully retract, without interference, as a pocket door into a cavity such as the pocket frame 304. According to one embodiment, the primary storage position is defined by the handle base 120 and handle member 121 being retracted into the second portion 113 of the recessed channel 111.
In one embodiment, when the handle base 120 and handle member 121 are disposed in a first retracted orientation, the handle base 120 and handle member 121 are located in the recessed channel 111 and extended in a first direction interior to and along a face portion of the recessed channel 111.
The handle assembly 100 may be oriented in a secondary storage position. In an embodiment, when the handle assembly 100 is in the secondary storage position, the handle base 120 and handle member 121 are retracted into the recessed channel 111 so as to be flush with a top surface of the rim 114 of the housing 110. In operation, when the handle base 120 and handle member are retracted into the secondary storage position (i.e., stored in the recessed channel 111), the latch member 307 of the panel 301 is in a position configured for engagement with the latch coupler 306 of the outer frame 302. According to one embodiment, the secondary storage position is defined by the handle base 120 and handle member 121 being retracted into the first portion 112 of the recessed channel 111.
In one embodiment, when the handle base 120 and handle member 121 are disposed in a second retracted orientation, the handle base 120 and handle member 121 are located in the recessed channel 111 and extended in a second direction interior to and along a face of the recessed channel 111.
Although this disclosure has been set forth in terms of certain embodiments, other embodiments which are apparent to those of ordinary skill in the art in view of the present disclosure, including embodiments that do not provide all of the features and advantages set forth herein, are also within the scope of the claims. The scope of the present invention is defined only by reference to the appended claims and equivalents thereof
