Windows and secure corner assemblies are generally described. The windows may include a sash having stiles arranged on vertical sides thereof and rails arranged on horizontal sides thereof. Primary reinforcement members may be arranged within the stiles. Secure corner assemblies may be configured to be arranged within corners of the sash formed by intersections of the stiles and the rails. The secure corner assemblies may include at least one secondary reinforcement member arranged on an external surface of one of the rails, such as a top rail. A tilt mechanism may be configured to be coupled to a primary reinforcement member and the at least one secondary reinforcement member, thereby providing a continuous reinforcement connection around the window sash. Vinyl windows using corner assemblies according to some embodiments may have increased pressure ratings compared to vinyl windows that do not include such corner assemblies.

A device for enabling a wheelchair user to enter and exit the wheelchair includes a stabilizing frame. The stabilizing frame has two slide rails to which a base plate is movingly attached. An electric motor drives a leadscrew, causing the base plate to move along the slide rails. A telescopic column is vertically mounted onto the base plate. The seat assembly, including handlebars and a seat platform, is rotationally attached to the top of the telescopic column. The telescopic column is extended and collapsed by a linear actuator, raising and lowering the seat assembly. A stationary non-rotational rod is vertically mounted onto the telescopic column. When a user sitting on the seat platform exerts a moment force on the stationary rod, the seat assembly rotates about the stationary rod. A locking mechanism prevents the seat assembly from rotating when the user is transferring to or from the seat platform.
