Description

Lock assembly with trigger handle

The present invention relates to the field of door handle sets and door locks. More specifically, the present invention relates to a handle including a trigger in a lock assembly.

Door handle sets and door locks are usually installed in residential and commercial environments. The handle set includes a latch assembly that can be actuated by a mechanism. The latch assembly is used to maintain a door in a closed position using a bolt that moves between an extended position and a retracted position. In existing latches, the bolt is actively pulled between the extended position and the retracted position. This pulling of the lock bolt is usually the result of turning a door knob or a latch of the handle set. In existing latches, the latch is a spring latch, which means that the latch is always loaded by the spring, and the latch retracts only when the user operates the knob or thumbpiece installed on the surface of the handle assembly .

Pushing and pulling of the lock bolt can also be accomplished by activating a trigger. Some triggers need to be actuated with the thumb and require significant thrust. The thumb button is also a separate piece positioned above the handle of the handle set, which is not visually appealing.

Generally speaking, the present invention relates to a latch assembly for internal and external doors. The present invention generally relates to a handle set with or without a traditional locking cylinder. The latch handle assembly includes an internal spring actuation mechanism.

In a first aspect, a latch handle assembly assembly is described. The latch handle assembly includes a handle, a trigger and a latch driver. The handle has a handle part and a top mounting part extending from an escutcheon. The top mounting part has a top surface and a bottom part at least partially shielded by the handle part. The trigger includes an outer end positioned along the bottom of the top mounting part and an inner end extending to the decorative cover. The trigger can pivot around a pivot point located in the decorative cover. The latch driver can move between a neutral position and a latch actuation position in response to the activation of the trigger.

In another embodiment, a method for operating a latch handle assembly is described. The method includes the following: in response to actuation of an outer end of a trigger, the trigger pivots about a pivot point located in a decorative cover, and pivoting the trigger causes the trigger located in the decorative cover An internal end of the trigger actuates a latch driver, and actuation of the latch driver causes the latch driver to move between a neutral position and a latch actuation position.

In yet another aspect, a latch handle assembly used on a door is described. The latch handle assembly includes a handle, a trigger, a latch driver and a latch assembly. The handle has a vertical handle part and a top mounting part extending away from a decorative cover mounted on the door in a horizontal direction. The top mounting part has a top surface and a bottom part at least partially shielded by the handle part. The trigger includes an outer end positioned along the bottom of the top mounting part and an inner end extending to the decorative cover. The trigger can pivot around a pivot point located in the decorative cover. The latch driver can move between a neutral position and a latch actuation position in response to the activation of the trigger. The latch assembly includes a lock bolt that can move between an extended position and a retracted position in response to the activation of the trigger.

The present invention generally relates to a handle set having a trigger to actuate a latch assembly to open a door. The handle includes a trigger at least partially covered by a handle. Different from other trigger-actuated handle sets, the trigger described herein is beautiful, easy to use and safe. When the trigger is actuated, a latch driver moves from a neutral position to a latch actuation position, which allows a user to open the door.

It should be noted that some existing devices attempt to create a more visually appealing handle set by positioning the actuation mechanism in the handle. However, these actuation mechanisms have obvious disadvantages. For example, the pivot point of the actuation mechanism can be located outside the cover (for example, on a part of the handle) and therefore is easily broken and less safe. The pivot point of the actuating mechanism is generally also located in a direction normal to the door, and it is in the way when the door handle is used without the need to actuate the trigger. In addition, positioning a trigger on the handle itself requires a significantly more complicated linkage set with one of the actuated bolts. By comparison, the trigger-actuated handle set described herein only requires a simple linkage group similar to a thumb-actuated handle set mechanism. This results in a handle set with known safety features while improving the overall user operation.

FIG. 1 shows a latch handle assembly 100 according to an embodiment of the present invention. The latch handle assembly 100 includes at least one decorative cover 102, a handle 104 and a trigger 106. In the example shown, the latch handle assembly 100 may also include a second decorative cover 110; however, the second decorative cover 110 is not required.

The handle 104 includes a top mounting portion 120 having a top surface 124 and a bottom 126. A handle portion 128 extends from the top mounting portion 120 in a substantially vertical direction. The handle portion 128 partially shields at least part of the bottom 126 of the top mounting portion 120. In one example, the handle 104 also includes a bottom mounting portion 122. The handle 104 may also include a bottom mounting portion 122 connected to the handle portion 128 at an end opposite to the top mounting portion 120.

The decorative cover 102 covers the internal mechanism of the handle assembly when installed on a door, and also provides a beautiful surface. As shown, the decorative cover 102 has a decorative rectangular shape, but circles, squares, and other shapes of the decorative cover 102 are within the scope of the present invention. In addition, a second decorative cover 110 can also be included in the latch handle assembly 100. The bottom mounting portion 122 extends from the second decorative cover 110. Depending on the situation, the decorative cover 102 may be formed of metal or plastic.

In some embodiments, the decorative cover 102 may also include a lock cylinder 130. The lock cylinder 130 is configured to accept a key or other unlocking mechanism. A mechanical key (not shown) can be inserted into the lock cylinder 130 to mechanically unlock the latch handle assembly 100.

In an example embodiment in which the latch handle assembly 100 is mounted to an outer side of a door (not shown), the lock cylinder 130 communicates with a lock assembly (not shown). The exemplary lock assembly includes a lock mechanism that requires a key, a deadbolt, or a lock bolt or other similar types. In an embodiment in which the latch handle assembly 100 is installed on the inner side of a door, the latch handle assembly 100 may not include a lock cylinder 130.

In another alternative example, the decorative cover 102 may include an electronic lock assembly (not shown) useful for receiving an unlock command. The electronic lock assembly may include a small keyboard. In use, a user enters a predetermined pass code on the keypad, which is used to unlock the door. In an alternative embodiment, a biometric sensor is used instead of a keypad. For example, a household can store a fingerprint in the biometric control system. The user moves a finger across the sensor, and the sensor transmits the sensed fingerprint to a control circuit. The control circuit compares the sensed fingerprint with a stored fingerprint, and can allow entry into the building when the sensed fingerprint matches the stored fingerprint. In yet another embodiment, there is no keypad. A user can use an RFID tag, which allows a motor to be activated when the correct RFID tag is detected.

FIG. 2 shows the interior of the latch handle assembly 100. The interior of the decorative cover 102 includes a housing that defines a recessed area for internal components, such as a housing assembly 200. The interior of the decorative cover 102 also includes an attachment mechanism (not shown) for connecting the top mounting part 120 to the decorative cover 102. The inside of the second decorative cover 110 also includes an outer shell defining a recessed area for internal components, such as an attachment mechanism (not shown) for connecting the bottom mounting portion 122 to the second decorative cover 110.

The housing assembly 200 is configured to connect to and communicate with a latch assembly (not shown). The latch assembly includes a latch bolt that can move between a retracted position and an extended position. The latch assembly is arranged in a hole of the door (not shown) and can be manually actuated by the trigger 106. The trigger 106 can extend and retract the latch bolt.

The latch bolt linearly moves in and out of a barrel between a retracted position and an extended position. When the latch bolt is retracted, one end of the latch bolt is substantially flush with a strike plate and a hole in the door. When the latch bolt extends, the latch bolt protrudes through an edge hole in the door to be positioned in an opening of a bolt piece (not shown) adjacent to a side pillar of the door. Typically, the bolt is attached to the jamb using fasteners. The term "inner" is widely used to mean an area inside or inside a door, and "outside" is widely used to mean an area outside of a door. In addition, a retracted position is widely used to indicate an "unlatch" position and an extended position is widely used to indicate a "latch" position.

In one embodiment, the interior of the decorative cover 102 also includes a locking bolt mechanism 202, such as an internal locking bolt (not shown). The locking bolt mechanism 202 communicates with the lock core 130 to provide a lock member.

FIG. 3 is a side view of the latch handle assembly 100 installed on a door B. FIG. The latch handle assembly 100 includes at least one decorative cover 102, a handle 104 and a trigger 106. The decorative cover 102 and the second decorative cover 110 are attached to the door B spaced apart from each other.

In the illustrated embodiment, the top mounting portion 120 and the bottom mounting portion 122 extend from the decorative cover 102 and the second decorative cover 110 and perpendicular to the door B. The handle portion 128 extends from the top mounting portion 120 to the bottom mounting portion 122 in a direction substantially parallel to the door B. The handle part 128 is vertically connected to the top mounting part 120 and the bottom mounting part 122. However, in other embodiments, the top mounting portion 120 and the handle portion 128 may have other shapes (such as an arc shape) or be connected at an angle other than 90 degrees.

The handle 104 includes a top mounting portion 120 having a top surface 124 and a bottom 126. The top surface 124 and the bottom 126 are opposite to each other. The bottom 126 also includes a recess (not shown). The recess is sized and shaped to accept at least a part of the trigger 106. A handle portion 128 extends downward from the top mounting portion 120 such that the bottom portion 126 is at least partially covered by the handle portion 128. The trigger 106 is also at least partially covered by the handle portion 128. As shown, when the latch handle assembly 100 is installed on the door B, the trigger 106 is positioned closer to the door B than the handle portion 128.

The trigger 106 is positioned below the bottom 126 of the top mounting part 120 and extends into the decorative cover 102. The trigger 106 includes a pivot point (see below in conjunction with FIGS. 8-9) located in the decorative cover 102. As shown, when the trigger 106 is in the neutral position, it is positioned along the bottom 126 of the top mounting portion 120.

The decorative cover 102 accommodates the housing assembly 200. The housing assembly 200 may be positioned outside the door B, or a part of the housing assembly 200 may be positioned in a part of the door B. The decorative cover 102 can also accommodate at least part of the locking latch mechanism 202.

FIG. 4 shows another view of the trigger 106 in a neutral position. The neutral position is when the trigger 106 is not activated by a user. The trigger 106 includes an outer end 402 and an inner end positioned in the decorative cover 102. The trigger 106 also includes a pivot point located in the decorative cover 102.

The handle 104 includes a top mounting portion 120 having a top surface 124 and a bottom 126. The bottom 126 is at least partially shielded by the handle portion 128. The trigger 106 is also at least partially covered by the handle portion 128. In the illustrated embodiment, the handle 104 may not include a bottom mounting portion.

FIG. 5 shows an exploded view of the latch handle assembly 100. The latch handle assembly 100 includes a decorative cover 102 and a second decorative cover 110. A handle 104 includes a top mounting part 120 connected to the decorative cover 102 and a bottom mounting part 122 connected to the second decorative cover 110.

The decorative cover 102 hides the housing assembly 200. The decorative cover 102 can also hide a locking latch mechanism (not shown). The decorative cover 102 also includes an attachment mechanism 502b to connect to the top mounting portion 120. The second decorative cover 110 includes an attachment mechanism 502 a to be connected to the bottom mounting portion 122.

The handle 104 as shown includes a top mounting part 120 and a bottom mounting part 122 connected by a handle part 128. The top mounting part 120 includes a top surface 124 and a bottom 126. In one embodiment, the bottom 126 includes a recess (not shown) that allows at least a portion of an outer end 402 of the trigger 106 to extend when the trigger 106 is in the actuated position.

The flip-flop 106 includes an external terminal 402 and an internal terminal 404. The outer end 402 is positioned at the bottom 126 of the top mounting portion 120 (eg, extends at least partially downward from the bottom 126). The inner end 404 extends through the decorative cover 102 and communicates with the housing assembly 200. The trigger 106 is configured to pivot at a pivot point 406 that is also located in the trim cover 102.

As mentioned above, the trigger 106 can pivot between a neutral position and an actuation position. When the trigger 106 is pivoted from the neutral position to the actuated position, at least a portion of the outer end 402 can move from an exposed position to a recessed position (as seen in FIGS. 8-9). When in the recessed position, at least a portion of the outer end 402 is positioned within a recess of the top mounting portion 120. When in the exposed position, at least some additional portion of the outer end 402 is exposed below the bottom 126 because the outer end 402 will protrude or be further spaced from the bottom 126 in the exposed position (corresponding to the neutral position of the trigger 106).

FIG. 6 shows a front view of the latch handle assembly 100. Line A is a vertical line passing through a cross section of the latch handle assembly 100. As shown, the latch handle assembly 100 is symmetrical along line A; however, this is not required. It is worth noting that from the front view of the latch handle assembly 100, the trigger 106 is blocked by the handle 104 (for example, behind the handle portion 128 and below the top mounting portion 120).

FIG. 7 shows a cross-sectional view of the latch handle assembly 100 along the line A of FIG. 6. The latch handle assembly 100 includes a decorative cover 102 and a second decorative cover 110. The handle 104 extends between the decorative cover 102 and the second decorative cover 110. The handle 104 is connected to the decorative cover 102 at the top mounting part 120 and to the second decorative cover 110 at the bottom mounting part 122. A handle portion 128 extends between the top mounting portion 120 and the bottom mounting portion 122.

The top mounting portion 120 includes a recess 702 that is shaped to receive an outer end 402 of the trigger 106 when the trigger 106 is in the actuated position.

The decorative cover 102 accommodates the housing assembly 200 and an optional locking latch mechanism 202. The decorative cover 102 also accommodates at least a part of the pivot point 406 and the inner end 404 of the trigger 106.

8-9 show further detailed cross-sectional views along line A of the latch handle assembly 100 in the neutral and actuated positions. Specifically, FIG. 8 shows another cross-sectional view along line A of the latch handle assembly 100 in a neutral configuration. In the example shown, the latch handle assembly 100 includes a handle 104, a trigger 106, and a housing assembly 200.

The trigger 106 includes an outer end 402 positioned below the bottom 126 of the top mounting portion 120. For example, when installed on a door, the trigger 106 is positioned below the bottom 126 and closer to the door than the handle portion 128. When the trigger 106 is in a neutral configuration, at least a part of the outer end 402 is positioned outside the recess 702. In some embodiments, in the neutral configuration, the entire outer end is positioned outside (below) the recess 702. The trigger 106 pivots about the pivot point 406 in a substantially vertical direction when installed on a door.

The housing assembly 200 includes a compression bracket 802 in communication with the inner end 404 and a spring 804. When installed on a door, the inner end 404 is positioned above the compression bracket 802, and the compression bracket 802 is positioned above the spring 804. The housing assembly 200 also includes a pinion gear 904, and the pinion gear 904 communicates with a latch driver 906. In an installed configuration, the pinion 904 and the latch driver 906 rotate about a longitudinal axis perpendicular to the door.

In a neutral configuration, the spring 804 is uncompressed and maintains the compression bracket 802 in an uncompressed configuration. For example, when installed, in the uncompressed configuration, the latch driver 906 maintains a latch bolt in a neutral position. When installed on a door, the compression bracket 802 does not provide a downward force on the spring 804 in the neutral configuration. The compression bracket 802 maintains an upward force on the inner end 404 of the trigger, and the outer end 402 is not positioned in the recess 702.

9 shows a cross-sectional view of the latch handle assembly 100 including a handle 104, a trigger 106, and the housing assembly 200 in a latch actuation position.

In the latch actuation position, the outer end 402 of the trigger 106 moves into the recess 702 of the top mounting portion 120 (for example, by a user action). This causes the trigger 106 to pivot at the pivot point 406 and the inner end 404 engages the compression bracket 802. Generally speaking, the pivoting movement is in a direction that is substantially parallel to the door on which the latch handle assembly 100 is mounted (in this case, a substantially upward movement).

The housing assembly 200 at least includes a compression bracket 802, a spring 804, and a latch driver 906. When the compression bracket 802 is actuated, the spring 804 is compressed, which causes the latch driver 906 to move from a neutral position to a latch actuation position. The latch driver 906 rotates a latch bolt, which allows the door to be opened.

When the latch handle assembly 100 is installed on a door, the movement of the compression bracket 802 is parallel to the door. The vertical movement of the compression bracket 802 causes the circular pinion 904 to rotate around a horizontal axis. The latch driver 906 also moves in a circular direction around a horizontal axis.

FIG. 10 shows an example embodiment of the housing assembly 200. The housing assembly 200 includes a compression bracket 802, a spring 804, and a circular pinion 904. The compression bracket 802 includes a plurality of teeth 902 that can mesh with a circular pinion 904. When the compression bracket 802 is actuated by the trigger 106, the compression bracket 802 moves in a linear direction, which causes the circular pinion 904 to rotate along a first axis. The first axis moves normally in the linear direction of the compression bracket 802. The circular pinion 904 is connected to the latch driver 906. When the circular pinion 904 rotates, it causes the latch driver 906 to also rotate. The latch driver 906 rotates a latch bolt, which allows the door to be opened.

When the trigger 106 is released, the spring 804 provides a force on the compression bracket 802, which causes the compression bracket 802 to move in an opposite linear direction. This causes the circular pinion 904 to rotate in an opposite direction along the first axis, which also causes the latch driver 906 to rotate in an opposite direction along the first axis.

FIG. 11 shows an alternative view of the housing assembly 200. The housing assembly 200 includes a latch driver 906 connected to the circular pinion 904. The circular pinion 904 causes the latch driver 906 to rotate along the first axis, which causes a latch bolt to move between an extended position and a retracted position, as discussed above.

In use, the latch handle assembly 100 is installed on a door. A user actuates a trigger 106, which allows the user to open the door. When the user does not apply force to the trigger, the latch bolt moves back to a neutral position, which maintains the door in a closed position. Instance
