The present invention provides a truck bed system with a plurality of powered actuators which can raise a raisable platform above the truck bed floor to create a second platform in addition to the truck bed floor surface. The additional or second truck bed platform allows the truck user to use the upper platform for carrying tools and other goods or materials, with the space between the truck bed floor and platform for storing or moving large flat items like lumber and plywood or drywall sheets without displacing or disturbing the contents stowed on the upper platform. The present invention also allows the upper platform to be used for stowing large items like lumber and plywood or drywall sheets, with the space between the truck bed floor and upper platform for carrying tools and other goods or materials. The present invention allows the space between the truck bed floor and the upper platform, when in a raised position, to be used as secure storage when the tailgate is locked. The plurality of actuators can be attached to the truck bed floor, the truck bed walls or integrated into the space within the truck bed side walls.

The subject matter of the invention are various methods, systems and devices and the ways of their installation/fitting/assembly of emergency opening of manholes (entry openings) or loading holes (door) in emergency situations, especially an emergency move/shift of movable components closing manholes (entry openings), exit openings, loading or unloading openings, from closed position into opened position, such as doors, manholes, hatches, gates, emergency exits, windows, window panes and other, especially in means of transport, construction furnishing devices and premises (buildings). The invention is connected with the use of pyrotechnic actuators which can be telescopic actuators, piston actuators or flexible ones, driven with propelling actuating agents which are in the form of gas generators, pressure of compressed gas or air, compressed air from a compressor or a material with shape memory.

A door operator having an automatic roller closes and opens a door attached to a doorjamb by a door hinge. The roller is actuated by a motor and housed within a protective roller casing affixed to the bottom of a door. The door operator may be integrated with a smart home, thereby allowing a user to close and open a door by voice command. The door operator may be retrofitted to existing doors. A door may also be modified such that only a magnet holds the door closed and a closed position such that the smart home door closing apparatus may be used to open a door. The roller may translate between an extended position engaging the floor below a door and a retracted position above the floor, either inside or adjacent to the door itself.

A motor vehicle is disclosed having a safety system that includes an electronic controller controlling an electronically controlled mechanism in response to inputs from a number of rear parking sensors to prevent movement of a rear closure of the motor vehicle in a closing direction when more than one object is sensed to be within a rear protection zone and the rear closure member is in a fully open position.

An inward-swing door driving device, including a motor, a worm wheel and worm reducer driven by the motor, a positive clutch, an unlocking cylinder and an unlocking connecting mechanism. The positive clutch includes an inner tooth, an outer tooth and an elastic element. The inner tooth is in transmission connection with the worm wheel and worm reducer, and the outer tooth is in coaxial transmission with a door shaft of an inward-swing door. The unlocking cylinder includes a cylinder push rod. One end of the unlocking connecting mechanism is in contact with the end portion of the cylinder push rod, and the other end of the unlocking connecting mechanism is connected with the inner tooth.

A harvesting machine includes a chassis, a ground-engaging mechanism for supporting the chassis, and a tank assembly mounted to the chassis for storing a crop material. The tank assembly includes a retractable door for at least partially covering an opening formed in a top of the tank assembly. A mobile sensor assembly includes a rod and a sensor for detecting a weather condition, such that the rod includes a first end coupled to the retractable door and a second end to which the sensor is coupled. The retractable door is operably moved between an open position and a closed position, and the mobile sensor assembly is rotatably moved between a deployed position and a stowed position as the door is moved between the open and closed positions, respectively.

A household appliance includes a housing, a door pivotably connected to the housing, a cable connected to the door, a roller in contact with the cable, and a motor configured to drive the roller to move the cable such as to effect a pivoting movement of the door.

A railroad hopper car body includes a set of hopper and hopper discharges. Egress of lading from the discharges is governed by movable doors that swing between a closed position and an open position. The motion is driven by a mechanical transmission that is itself driven by an actuator. Each pair of doors is driven by a single actuator. The actuator is mounted to act through the center sill. A portion, or substantially all, of the actuator may be mounted in a predominantly squat, vertical orientation within the center sill. In alternate embodiments, the transmission output may be bifurcated. The center sill bottom flange may be narrower adjacent to the doors. The mechanism may have a secondary lock. The mechanism may have an auxiliary manual release.

A crop duster dump gate opens and closes to turn on and off the flow of payload out of the hopper. The traditional mechanical gate is actuated by the pilot through mechanical linkages. The effort required by the pilot to open and close the gate requires significant force and can lead to fatigue or injury. The powered dump gate system is an add-on to the existing traditional mechanical gate system by a booster that is hydraulic, pneumatic, or electric. The powered dump gate eliminates strenuous effort by the pilot and requires no change to the pilot's work environment and methods.
