Abstract: A motorcycle lift and stand apparatus for manually lifting and supporting a motorcycle in an elevated position for cleaning or other maintenance. The motorcycle lift and stand apparatus is a collapsible support system which can be quickly and easily raised from a storage position to an operational position by the use of a lever arm. Operation of the lever arm easily lifts an entire motorcycle into a raised position above a ground plane. The apparatus has a cycle support surface formed by two cylinders spaced apart by rigid members and a pair of upright support units. The lever arm is affixed to one of the upright support units such that when the arm is lowered, the upright support units raise the cycle support surface from the ground plane position to an elevated position with sufficient force to lift the motorcycle.

Abstract: A tray and bib food catching apparatus for use in child feeding or the feeding of individuals where spilled food may be likely. The tray and bib food catching device allows food, including liquids, to be captured and retained in a pocket formed by the bib when used in conjunction with a tray. In one embodiment, the tray and the bib are integrally formed. The bib has an opening for the neck of the child or other user and has two arm openings. The arm openings are located closer to the tray than the neck opening such that when the bib is placed over the head and arms of a user, the upper arms and shoulder tend to support the fabric of the bib in an elevated position at the sides and allow the bib to sag into a pocket-like formation at the center immediately below the neck opening. The tray may also be made of a rigid material and be generally U-shaped at the edge facing the user.

Abstract: A doorholder for retaining a door in an open position by magnetic interaction with an armature secured to the door has an electromagnetic flux generator which includes a core having a face confronting the armature and a coil of wire surrounding the core. A cup having an inside diameter somewhat greater than the coil outside diameter receives the coil, the core extending from the face to the cup bottom. A power control circuit including a resistor circuit controls electrical power supplied to the coil, the power control circuit being mounted on a circuit board situated between the coil rear surface and the cup bottom. The resistor circuit being situated in sufficiently close proximity to the cup bottom for transfer of heat from the resistor circuit to the cup.

Abstract: A door lever assembly for disengaging an unlocked latch of a lockable door latch assembly includes a lever handle rotatably connected to a trim housing supporting a stop plate. A cam is operably connected to the lever handle and positioned to rotate in response to rotation of the lever handle, converting its rotational movement to linear movement of a movable slider positioned adjacent to the cam. A lift arm is operably connected to vertical rods of the door latch assembly and an over-ride spring is connected between the slider and the lift arm. The over-ride spring transmits motion of the slider to the lift arm to lift the lift arm and the connected vertical rods when the door latch assembly is in an unlocked position. The over-ride spring compresses in response to slider movement when the blocking slide is positioned to block movement of the lift arm when the door latch assembly is in its locked position, preventing damage to components of the door lever assembly.

Abstract: A door lever assembly having a locked and an unlocked position includes a trim housing and a lever handle and cam rotatably connected to the trim housing. A rotatable shaft extends between the lever handle and the cam, with the shaft defining a connection groove therethrough to provide access to a shaft interior. The shaft interior is configured to a accept a pin for connecting the cam and the shaft. This pin can be resettably disconnected following controlled slippage of frictional contact surfaces in response to excessive force applied to rotate the cam.

Abstract: A door lever assembly includes a lever handle rotatably connected to a trim housing. A pair of guide rods positioned in the trim housing support a stop plate and a movable slider. A cam is operably connected to the lever handle and positioned to rotate in response to rotation of the lever handle, converting its rotational movement to linear movement of the movable slider positioned adjacent to the cam. A lift arm is operably connected to the slider to engage and disengage door latches in response to movement of the slider when the door lever assembly is unlocked. When the door lever assembly is locked, an over-ride spring connected between the slider and the lift arm compresses in response to slider movement, preventing damage to components of the door lever assembly. When the door lever assembly is unlocked, a pivot rotates to control contact between the slider and the stop plate.

Abstract: An electromagnetic coil for use in a doorholder for retaining a door in an open position by magnetic interaction with an armature secured to the door includes a coil of wire for surrounding a core within a cup. A power control circuit including a resistor circuit, controls electrical power supplied to the coil, the power control circuit being mounted on a circuit board situated between the coil rear surface and the cup bottom. The resistor circuit being situated in sufficiently close proximity to the cup bottom for transfer of heat from the resistor circuit to the cup. The power control circuit also includes a low resistance circuit coupled to the resistor circuit, the low resistance circuit including a fusible link, the fusible link being selected to carry current when the power input terminals are coupled to a lower voltage power source and to stop carrying current when the power input terminals are coupled to a higher voltage power source.

Abstract: A door lever assembly having a locked and an unlocked position includes a trim housing and a lever handle rotatably connected to the trim housing. A cam is rotatably connected to the trim housing, and a pin mechanism is movably positionable to connect with the lever handle. A slider is attached for movement in the trim housing in response to rotation of the cam, anda lift arm is connected to the slider. The lift arm is rigidly movable with the slider when the door lever assembly is in its unlocked position and the lever handle is rotated. When the door lever assembly is in its locked position, the lift arm pivots toward the cam to disengage the pin mechanism from its connection between the lever handle and the cam.

Abstract: A door lever assembly for disengaging an unlocked latch of a lockable door latch assembly includes a lever handle rotatably connected to a trim housing and a cam operably connected to the lever handle. The cam is positioned to rotate in response to rotation of the lever handle, converting its rotational movement to linear movement of a movable slider positioned adjacent to the cam. An electrically activated block arm is positionable to prevent movement of the movable slider, effectively locking the door lever assembly.

Abstract: A mullion assembly mountable in a door frame includes a bottom fitting attached to a floor and a top fitting attached to the door frame above the bottom fitting. The top fitting supports a latch engagement assembly for engaging a latch assembly positioned in a mullion cavity of a mullion. The latch assembly has a latch extendable from the mullion cavity to engage the latch engagement assembly supported by the top fitting and hold the mullion in a fixed position. Retraction of the latch is controlled by a key lock assembly connected to the latch assembly through an actuating link assembly. The key lock assembly permits key controlled disengagement of the latch from the latch engagement assembly, followed by temporary removal of the mullion from its position in the door frame.
