A handle set includes a main body that has a handle and a faceplate positioned around the handle, the faceplate having a toggle aperture. The handle set includes a locking mechanism that includes a locking piece that has a locking notch. The locking mechanism includes a toggle positioned within a toggle housing, the toggle being movable relative to the toggle housing. The toggle includes a toggle tail configured to be received into the locking notch. The toggle includes a toggle head removably attached to the toggle tail, the toggle head being at least one of a privacy attachment button and a passage attachment button. At least a portion of the privacy attachment button extends from the toggle aperture and beyond the faceplate. The passage attachment button interfaces with the toggle housing to prevent relative movement between the passage attachment button and the toggle housing.

The present invention relates to the field of lockset and provides a lock body a latch bolt installation structure comprising a latch bolt body having a driving part and a latch part, wherein the latch part is detachably connected with the driving part. The latch part is configured with a male part inserting into a female part on the driving part; the female part comprises a first installation position and a second installation position for installing the latch part; when the latch part is installed at the first installation position, a flat surface of the latch part faces towards a first direction; when the latch part is installed at the second installation position, the flat surface of the latch part faces towards a second direction which is opposite to the first direction. The present invention is advantageous in fast reversal of the installation of the latch bolt as well as the construction progress control and user experiences.

A door lock with a reinforced fireproof effect includes a lock body mounted on a door and inner and outer operating units mounted to two sides of the door, respectively. The lock body includes inner and outer chassis made of ferrous material or stainless steel having a melting point higher than 1300° C. Inner and outer fixing members coupled with the inner and outer chassis are also made of ferrous material or stainless steel. Thus, these components of the door lock are less likely to melt during a fire, reducing the spreading speed of the fire.

An exemplary catch assembly is configured for installation into a spindle, and generally includes a holder, a first catch, a second catch, and a bias mechanism. The holder is configured for mounting within the spindle. The first catch is mounted for movement relative to the holder between a first projected position and a first depressed position. The second catch is mounted for movement relative to the holder between a second projected position and a second depressed position. The bias mechanism biases the first catch toward the first projected position and biasing the second catch toward the second projected position.

An appliance may include a cabinet defining an opening, a door attached to the cabinet that allows selective access to the opening, a handle attached to the door, and a handle endcap that may removably connect the handle to the door. The handle endcap may include a slide lock receiver frame and a slide lock base removably attached to the slide lock receiver frame. The slide lock receiver frame may include a locking tab wall and an outer case. The slide lock base may include a base body, a resilient locking tab and a tab protrusion. The resilient locking tab may be joined to the base body to selectively deflect in an inward direction, the tab protrusion extending in an outward direction to motivate the resilient locking tab inward in response to slidable movement of the tab protrusion along the locking tab wall.

A handle for an access panel of a heating, ventilation, and air conditioning (HVAC) system includes a handle portion configured to be disposed on a first side of the access panel. The handle portion includes a first prong comprising a first tooth and a second prong comprising a second tooth. The first prong and the second prong are configured to extend through the access panel. The handle also includes a latch portion configured to be disposed on a second side of the access panel. The latch portion includes a passage extending therethrough and configured to receive the first prong and the second prong. The latch portion includes a first tooth recess and a second tooth recess. The first tooth is configured to engage with the first tooth recess and the second tooth is configured to engage with the second tooth recess to secure the handle portion and the latch portion to one another and to secure the handle to the access panel in an installed configuration of the handle. The handle also includes a gasket configured to be disposed between the handle portion and the latch portion in the installed configuration of the handle. The handle is adjustable, relative to the access panel, between a first position and a second position in the installed configuration.
