A security hood assembly for a holster includes a hood that is movably supported in association with a holster body so that the hood extends over a portion of a holstered handgun or other service item when the hood in a closed position, to prevent unauthorized removal of the service item. A lever may be operably coupled to the hood for driving the hood toward an open position, to allow the service item to be removed from the holster. In some embodiments, a latch mechanism releasably engages when the hood is in the closed position to prevent the hood from being opened through direct manipulation of the hood. The hood is preferably formed of a substantially rigid material, such as injection molded plastic. Holsters including the security hood assembly may also include internal retention devices, hood biasing mechanisms, and electronic devices responsive to opening of the hood.

A protective hood assembly (6) for a tool machine (2) is formed of a housing with a protective hood (10), to a securing assembly (8, 8′, 8″) relative to the housing (4) in different rotary positions, wherein at least one lock-in part (30, 30′) is provided, which can be brought along a direction of installation (M) into a receiving region (36) of a locking housing (16) of the securing assembly (8) and at which, by rotating, can be brought into a bayonet-like engagement and wherein locking means (32, 32′) are provided on the protective hood, the locking means being capable of being locked in different locking positions with counter locking means (26, 26′) of the securing assembly (8). The receiving region (36) is limited on a side facing the housing (4) at least in part by an abutting wall (34, 34′, 34ä, 34″b), which is mobile.

A hood assembly for a machine includes an enclosure within which at least one exhaust aftertreatment device is mounted. The engine hood assembly may be preassembled so that the exhaust aftertreatment system is integrated into the enclosure. This may allow the hood assembly to be assembled to the machine and the exhaust aftertreatment system mated to an exhaust pipe from the engine as a unit while the machine is being built on an assembly line. The engine hood assembly may include ventilation openings to assist in heat rejection from the engine compartment and from the exhaust aftertreatment devices. The hood assembly of the present disclosure finds particular application in assisting large track type tractors in meeting ever more stringent exhaust emission requirements without extensive and expensive redesign alternatives.

Dust and debris resulting from the sawing or cutting of concrete masonry units, blocks, bricks, tiles and other masonry products is collected via a three point dust and debris collection system. A movable work supporting table for cooperation with a masonry saw has a grated surface, a vacuum chamber below the grated surface acting as one collection point or area, a heavy debris collection chamber below and in communication with the table vacuum chamber acting as another collection point or area, and a shroud or hood assembly extending rearwardly from the table adapted to extend about the sides and rear of the saw blade and including a vacuum chamber acting as a primary collection point or area. The system is highly effective in achieving dust capture.

This invention relates to a vehicle hood assembly that is operative to raise the rearward and frontward portions of a vehicle hood. The system includes an actuator selectively extendable to raise the rearward portion of a vehicle hood from a first position to a higher second position. A striker of novel design enables the frontward portion of the hood to rise as the rearward portion rises when the striker is engaged with a latch member. The latch member may be disengaged from the striker without extending the actuator, enabling the hood to reach a third position ideal for vehicle service and thus allowing a nonreversible-type actuator to be employed. A method of elevating the vehicle hood with respect to the vehicle body is also provided.

An energy-absorbing hood assembly for a vehicle includes upper, lower, and middle panels. The upper and lower panels respectively include first and second interface surfaces. The upper panel is preferably secured to an inner surface of an outer panel. The middle panel has opposing first and second surfaces defining an asymmetric waveform profile, preferably having a polygonal geometry. The middle panel member is secured to the first and second interface surfaces at preselected locations along the upper and lower surfaces, thereby defining a plurality of laterally oriented asymmetric channels. The asymmetric waveform profile is configured with distinct amplitudes and wavelengths along different regions of the hood assembly, each configured to provide different predetermined levels of absorption and attenuation of kinetic energy imparted to the hood assembly by objects upon impact therebetween. Ideally, the lower and middle panels are respectively configured to controllably fail at first and second predetermined crush loads.

A vehicle hood assembly is provided with a pair of fender panels that attach to a central panel at a first attachment point and a second attachment point. The fender panel is L-shaped in cross-section between the first attachment point and the second attachment point such that it functions as an air management channel. The central panel and the fender panels are preferably injection molded parts. The present invention also includes a method for manufacturing a vehicle hood.

A rotisserie oven is provided having a radiating heating system in combination with a convection heating system to prepare raw meat and poultry food product inside of a cooking chamber. A spit assembly carries the food product, and includes components that are detachable to assist in cleaning. The oven further includes a steam cleaning assembly that is integrated with the convection heating system that assists in grease removal from the components inside the cooking chamber. A humidity removal system regulates the moisture level inside of the cooking chamber during food preparation. A rotisserie oven is provided of the type that includes a cooking chamber having at least one open end closed by a movable door assembly. A radiating heating system is disposed in the cooking chamber and receives electricity to produce radiating heat to cook food carried by a rotating spit assembly. A hood assembly is supported by the cooking chamber, and defines a filtration chamber that receives incoming grease-laden air from the cooking chamber and houses at least one filtration member drawing the incoming air therethrough towards a hood outlet. The hood assembly and cooking chamber move together as the rotisserie oven travels from one location to another.
