Abstract: An adjustable armrest includes a housing with opposite walls. Each of the walls has a bore formed in it. The boxes support a pivot pin with a gear so that the armrest is pivotable on the pin. A ratchet with a pawl is pivotably connected to and carried by the armrest. The ratchet is also configured so that the pawl may engage the gear to define incremental ratcheting movement of the armrest on the pin when the armrest is pivoted in one direction. There is also provided a cam ring selectively movable with the armrest for rotational engagement with the gear. The cam ring has an exterior cam surface that contacts a portion of the ratchet and pivots the ratchet clear of engagement with the gear when the armrest is pivoted in another direction. The new armrest incorporates fewer components lowering cost of production, improving torsion force and load bearing capabilities, improving life of the furniture piece and strengthening armrest and furniture piece assembly.

Abstract: A new latch device for a screen door includes inside and outside handle assemblies. Each assembly has a lever adapted to be pivotably connected, respectively, to the inboard and outboard side of the screen door. The inboard lever has a paddle at one end and a stem at the other. The stem extends through an opening formed in the screen door. When the paddle is depressed, the stem moves along a cam surface formed in the outboard lever. This causes the outboard lever to disengage the fastener on the solid door to disconnect the solid door from the screen door. Additionally, when the screen door is in its latched position and not connected to the solid door, depressing the paddle causes the latching end of the outboard lever to disengage the doorjamb so that the screen door can be moved independently from its latched position into its open position.

Abstract: An all terrain vehicle with a low profile low friction seat support is described. The vehicle includes a rail in a longitudinal direction of the vehicle and a seat support with a top member and a bottom member. The seat support is adapted for securing on the rail, and the seat support is adjustable in position in the longitudinal direction of the vehicle. A lock is provided for releasably locking the seat support in a forward position, a rearward position and therebetween. A low friction support member is positioned between the top and bottom members. At least two channels are formed in the top member. One of the channels matches the shape of the support member, and the other channel matches the shape of the rail for close registration between the top member and the support member and the rails. The seat support is highly compartmentalized, sturdier, and safer for vehicle occupants.

Abstract: An improved pivot foot for a trailer jack of the type having a housing and a telescoping member that can be raised and lowered in and out of the housing eliminates the need for use of blocks between the jack and ground surface. The pivot foot includes a base and a pair of opposite sidewalls upstanding from the base. Each of the sidewalls has a cam slot and an ear slot formed in it. A bridge tab extends between the sidewalls for supporting the jack. A bore extends through the telescoping member of the jack. A pivot ring is provided, and it has a pair of outwardly extending ears. The pivot ring is sized to move freely along the length of the telescoping member. A cam pin extends transversely through the bore of the telescoping member and connects the sidewalls and the jack. The shaft of the cam pin travels within the cam slots to lift and rotate the foot assembly at a pivot defined by the ears of the pivot ring when the telescoping member is raised into the housing of the jack.

Abstract: An adjustable seat pedestal that allows a user to adjust the height of the seat without sacrificing ride quality. The seat pedestal has a top carrier onto which a seat is mounted and a base that is mounted to the floor of a vehicle. A scissor linkage is employed to allow movement of the carrier toward the base when force is applied through the seat to the carrier when the vehicle hits bumps and forces the user downward. An air bag biases the top carrier upward away from the base. As the upper ends of the scissor linkage move closer together by being pushed upward, a sliding end of the scissor linkage is restrained from movement inward and therefore, limits the maximum height of the pedestal. The pressure in the air bag may be varied which will not change the height above the maximum, but will change the ride quality.

Abstract: A vent cover for covering an opening in a building structure to vent its interior is provided. The vent cover includes a hollow cover member with an open bottom for positioning over and covering the opening in the building and a front end with an opening. A grill is removably secured in the opening in the front end of the cover member. The grill has a plurality of partitions. Each of the partitions is defined by intersecting members, which have a tapered cross section for accelerating the flow of air through the grill. The grill also has a splash guard and an overhang structure optimal for preventing rain, snow and water from entering the grill and the opening in the building structure. The cover member may be aerodynamically shaped for use atop vehicles such as trailers and RVs.

Abstract: A helium charged refrigerator is capable of cooling a refrigerator box to a temperature of 6° C. (43° F.) and the freezer compartment to a temperature of ?9° C. (15° F.) when the ambient is at a temperature of 43° C. (110° F.). The total cubic area cooled is greater than or equal to six cubic feet. The unit includes a condenser, an evaporator, a liquid ammonia tube, and a gas heat exchanger. The liquid ammonia tube includes two vertical sections. The second section is downstream of the first and is noncontiguous with the heat exchanger so that no heat is exchanged between flowable fluids flowing in the second vertical section and in the heat exchanger. The heat exchanger includes modifications to its inner and outer tubes to produce an increase in surface area of the corresponding surface.

Abstract: A clamp frame is disclosed for securing a window frame in a building structure opening by hand without using fasteners. The clamp frame comprises a unitary extruded plastic member that defines a cross section having an integrally formed connection element that mates with a complementarily shaped portion of a window frame to connect the clamp frame and the window frame without fasteners along the length of the clamp frame. The cross section includes a clamp element having at least a leg and a lever. The leg and lever are each connected to the connection element by a living hinge and are movable relative to the connection element between an open position and an overlapping locked position, which results in a clamp load holding together the clamp frame and window frame without the use of fasteners. One end of the leg of the clamp element is constantly urged against the building structure by the lever when the clamp element is in the locked position.

Abstract: A plastic window frame assembly is disclosed that includes rigid molded corner sections. Each of the corner sections has opposite ends. A pair of offset tabs extend outward from each of the opposite ends. The corners are molded so as to include integrally formed non-rigid seals. Lineal rail sections are located between the corner sections. Each of the rail sections has channels, one each formed in an exterior and an interior surface of the rail section for receiving, respectively, the offset tabs of the corner sections to locate and to align the corner sections with a rail section. The channels include a glazing channel extending along the length of the rail section for receiving a glass or plastic pane. The tabs are connected to a rail section such that the tabs and a portion of a rail section together define stake holds, each of which proceeds from an exterior surface of the frame and extends therethrough but does not penetrate the interior surface or the tabs of the frame.

Abstract: An automated control device for monitoring the position angle of an absorption type cooling system or refrigerator that circulates a refrigerant, an absorbent, and a diffusion agent within a conduit system includes a housing, a controller with a processor within the housing, a sensor in communication with the controller for measuring the angle of inclination of the refrigerator, and a stress counter connected to the controller for counting increments of stress induced into the cooling system. The tilt monitoring control method prevents system stress, which in turn prevents personal and property damage due to hydrogen gas leaks, fires and explosions.
