A method of assembling a door and a door assembly comprising an outer door shell and inner door supporting member therefor. The supporting member is hinged at one end to a door frame. The other end of the supporting member is slidably accommodated in and occupies the outer door shell through an aperture in a lateral edge of the door shell. The supporting member can carry a window glass holder, such as a channel strip screwed to the supporting member, and this combination is called a cartridge assembly. The cartridge assembly provides specific benefits for automobile and truck door applications where the cartridge assembly can have attached to it various window and latch components; such as the window glass regulator (including any electric motor and wiring therefor), the window glass guides, the window glass, door latch parts, latch operating and locking parts (including any electric actuators and wiring therefor) as well as a side impact resistant beam; before the outer door shell is slid over the cartridge assembly. The invention eliminates the need to manually install the various window and latch components inside a hollow door through apertures in the door.

A vehicle door and reinforcement assembly therefor comprising a reinforcing beam hinged at one edge to the vehicle and slideably accommodated in a cavity provided within the door. The door and beam are assembled by first hinging the beam to the vehicle and thereafter sliding the door onto the beam. Suitable fasteners secure the door to the beam.

Vehicle door assembly

A plastic container for planting tree seedlings in a mechanized process, and being in the shape of a projectile suitable for penetration into soil. The planting container is highly oriented in its longitudinal direction with a number of longitudinal grooves positioned on the inside, outside or both sides thereof. The grooves include slits and holes to permit drainage, egress of growing roots, and aiding in the self-destruction of the container after being injected into the ground with a seedling. The self-destruction can be further promoted by the use of stress cracking agents within the plastic material comprising the planting container.
