A commercial vehicle used for parcel delivery is installed with a control module. The control module communicates wirelessly with a transmitter to give control to the vehicle operator. The vehicle operator can access the vehicle's cargo compartment through the bulkhead door and/or the rear door solely by using the transmitter as opposed to manually actuating the door latch. A door actuator is added to the bulkhead door such that when the bulkhead door is wirelessly actuated the door opens without operator assistance, and the process of the door opening does not damage the vehicle. Additionally, the vehicle operator can initiate the control module to allow a push-button start and stop of the vehicle's ignition system. Such elements contribute to time savings and cost savings for parcel delivery operators.

A sash (62) of a window opening up to 180° and capable of tilting is mounted onto a fixedly installed frame profile (63) and houses a pair of superimposing sashes that fit tightly therein when in closure position, i.e. an upper stationary sash (65) and a lower movable-divertible sash (64), each of the sashes (64,65) provided with laterally extending shafts (49) for connection with sash (62), roller wheels (50) provided onto the shafts (49) of sash (64) that roll within a predefined path created by insert guide profile members (19) and diverter guide members (66,68) to alternately bring sash (64) in a position of superimposing sash (65) and a position of alignment with the same. Lifting mechanisms (46) provided with a regulatory screw (84) for adjusting the pretension of a spring component thereof and thereby the force required by the user for moving the sash (64) are installed within the vertically extending sides of the sash (62).

A retraction device includes a housing and a driving element guided in the housing between a parked position and an end position. A first end of a spring energy accumulator is connected to the housing. The spring energy accumulator is loaded to a maximum operating value when the driving element is in the parked position and is unloaded to a residual energy value when the driving element is in the end position. A second end of the spring energy accumulator can either be fixed to the housing or coupled to the driving element by means of a bistable coupling. The coupling has a blocking element that can be moved between the housing and the driving element.

An access opening closure device is provided for enabling passage of food or medication into a confined space without providing direct access from within the confined space to outside of the confined space. The device includes a housing assembly including a body and a cover, and a slide assembly including an access door and a frame. The body defines a receptacle and first and second openings. The housing assembly is pivotally coupled to the slide assembly and is movable from an operative position to a stowed, non-operative position.

A retraction device for movable furniture parts has a driver movable along a first guide path, which is movable between a retracted position and a parked position and is directly or indirectly pretensioned into the retracted position by an energy storage device. The driver can be coupled to an activator in order to move the movable furniture part into a closed position. A method uses the driver for opening and closing the movable furniture part and tensioning and releasing a retraction device.
