The present disclosure incorporates the disclosures of U.S. provisional application Ser. No. 62/430,089 filed on Dec. 5, 2016, Ser. No. 62/447,955 filed on Jan. 19, 2017, and Ser. No. 62/488,098 filed on Apr. 21, 2017 in their entirety herein.
The present disclosure relates to locks for entryway doors. In some embodiments, the present disclosure relates more particularly to multipoint locks. In some embodiments, the present disclosure relates more particularly to powered locks.
Builders have several options when designing entryways for homes or businesses. Typically, entryways either include a single hinged door or a set of double doors. If double doors are present, the two doors are typically arranged with the free, non-hinged edge of each door facing each other. An example prior art entryway 10 having double doors is shown in
Residents and business owners often rely upon cylindrical or mortise type locks, incorporated within the active door 16, in order to secure the entryway 10. In some instances, separate deadbolts are used, in addition to generally centrally located latches, to secure a door panel.
In addition to cylindrical or mortise type locks, builders have found that multipoint locks that have more than one latch or bolt, which are substantially spaced from one another, often provide a more secure closure that is able to seal and secure the entryway better than traditional single-point hardware. Because several latches or bolts are extended or retracted simultaneously, non-trivial effort is sometimes required to operate these multipoint locks.
In addition, smart home technology has begun to interconnect operation of several systems within a home or business. For example, deadbolts for door panels can now be locked or retracted by powered systems based upon an input from a key pad, fob, smart phone, or similar device. Many of the existing powered locks, however, include powered actuation of only a single deadbolt. Prior art powered locks also include substantial packaging placed on the interior or exterior face of the door panel.
The present disclosure provides locks and lock components that seek to improve upon existing locks.
An embodiment of the present disclosure includes a multipoint lock for securing a door panel. The multipoint lock includes a first latch, a second latch, a first hub rotatable with at least one of a thumb-turn knob or a key, and a second hub rotatable with a handle lever. Upward rotation of the handle lever causes both rotation of the first hub and rotation of the second hub in the same rotational direction
Another embodiment of the present disclosure includes a method of operating a multipoint lock. The method of operating the multipoint lock includes the act of locking the multipoint lock by lifting a handle lever. Lifting the handle lever extends at least one latch and causes rotation of a thumb turn drive hub in a first direction. The act of locking the multipoint lock also includes further rotating the thumb turn drive hub in the first direction with one of a key and a thumb-turn knob.
These and other aspects of the present invention will become apparent to those skilled in the art after a reading of the following description of the preferred embodiments, when considered in conjunction with the drawings. It should be understood that both the foregoing general description and the following detailed description are explanatory only and are not restrictive of the invention as claimed.
Exemplary embodiments of this disclosure are described below and illustrated in the accompanying figures, in which like numerals refer to like parts throughout the several views. The embodiments described provide examples and should not be interpreted as limiting the scope of the invention. Other embodiments, and modifications and improvements of the described embodiments, will occur to those skilled in the art and all such other embodiments, modifications and improvements are within the scope of the present invention. Features from one embodiment or aspect can be combined with features from any other embodiment or aspect in any appropriate combination. For example, any individual or collective features of method aspects or embodiments can be applied to apparatus, product or component aspects or embodiments and vice versa.
As used herein the term “latch” is defined as a member that slides or pivots into a catch, strike plate, hole, keeper, etc. to fasten or secure a door panel in a closed position relative to the frame of an entryway. The term “latch” as used herein may include structures referred to in the art as latches, latchbolts, and bolts. Latches may or may not be spring loaded unless specifically noted. Latches can extend vertically or horizontally in relation to the door panel of an entryway. As understood by one of ordinary skill in the art, the directions of rotation, relative to a clock, of handles, thumb-turn knobs, and key cylinders can depend upon whether a door panel is mounted for inswing or outswing operation and can be depend upon whether a door is hinged for left hand or right hand operation. Therefore, directional terms such as clockwise and counterclockwise are used in conjunction with their corresponding illustrated embodiment, and alternative mounting arrangements for changing swing or handedness would be understood by one of ordinary skill in the art.
In one embodiment, the present disclosure describes a multipoint lock configured for mounting onto a non-hinged edge of an active or passive door panel to secure the door panel relative to the frame of an entryway. The multipoint lock may include a thumb-turn knob and a handle lever. Upward rotation of the handle lever is configured to cause initial rotation of the thumb-turn knob and extension of at least some of the multiple bolts or latches within the multipoint lock. Further rotation of the thumb-turn knob may result in locking out the multipoint lock.
The multipoint lock 100 can be operated with a handle lever 18 and a thumb-turn knob 20 (

The operation of the multipoint lock 100 described above, should be understood as reflective of the operation of the lock from an interior side of the door panel. In some embodiments, the multipoint lock 100 may be operated similarly from the exterior of the door panel. For example, locking out the multipoint lock may occur by lifting the exterior handle lever, then turning a key cylinder. In other embodiments, locking and unlocking the multipoint lock 100 from the exterior side of the door may involve use of the key cylinder without the requirement or ability to lift the exterior handle lever.

The powered actuator 310 of the illustrated embodiment can include a motor 312, a controller 314, and a power source 316, such as a battery pack. The motor 312 can engage a coupler 318 which is attached to a drive screw 320. A drive nut 322 can be mounted along the drive screw 320. A drive bar connector 324 can be fixed to the drive bar 148 and configured to slide along the drive screw 320. The drive bar connector 324 can have a pair of spaced apart actuation surfaces 326.
The controller 314 can be configured to receive a wired or wireless signal and initiate operation of the motor 312 to rotate the drive screw 320. In some embodiments, the controller 314 receives a signal from a user interface, such as a key pad, disposed on a face of the door panel. In other embodiments, the controller 314 is configured to receive a wireless signal. The controller 314 can be configured to control the motor 312 to operate in two rotational directions, which in turn provides linear movement of the drive nut 322 in two linear directions, e.g. up and down. The controller 314 can be configured to sense and control the rate and direction of rotation of the motor 312 in response to external signals. The controller 314 can also be configured to sense and control the rate and direction of rotation of the motor 312 based upon the position of the drive nut 322 or drive bar connector 324.
As will be understood by one of ordinary skill in the art, rotation of the drive screw 320 can result in translation of the drive nut 322 along a longitudinal axis A (
In the illustrated embodiment of
To operate the motor 312 and other electrical components of the powered actuator 310, the power source 316 may take the form of a battery pack, such as a rechargeable battery. Preferably, the power source 316 is replenished without accessing the power source, e.g. without replacing the batteries.
In another, potentially less preferred embodiment (not shown), the power source 316 may be charged, or provided in the first instance, by being hard wired to the building's main source of electricity. For example, electrical energy could pass from the building to the door panel through the hinges of the door panel and travel by wire from the hinge to the power source 316. In a further embodiment, a solar cell could be mounted to an exterior face of the door panel to collect energy from the sun to be stored within the batteries of the power source 316.
