The structures and process for producing the structures of the invention enable extensive and efficient use of block scrap for slat manufacturing. The techniques employed advantageously accomplish two goals simultaneously, enabling scrap, such as block scrap, to be formed into longer effective lengths. Such longer effective lengths can then be cutably formed into slats of various sizes. The joinder of the block scrap is by deeply extending, finite interlock length finger joints which, once the material is cutably formed into slats, remain as relatively shallow and finite interlock length finger joints. The joints have the added benefit that they statistically “break up” any grain differences which would otherwise create warp, and enable long lengths of slat to be employed from several shorter lengths of scrap. An applied covering layer may be applied by wrapping or insertion. An ultraviolet resistant lacquer may be applied to the covering layer for long window life and attractive finish.

A device for damping movement of a telescopic guard including a plurality of box-shaped cover elements which slide inside each other in a defined direction. A plurality of leaf springs respectively connect the rear edges of the box-shaped elements to the rear edges of adjacent box-shaped elements. A guide rod is connected to each box-shaped element and is slidably connected to the adjacent box-shaped element. The guide rod slides in a friction element attached to an adjacent box-shaped element. Two circular bellows are fitted around the rod.

A vane for use in either a vertical or horizontal slatted covering for an architectural opening is contoured so as to have a substantially j-shaped cross-section. A main panel of the vane has a shallow s-shaped configuration and an elongated edge of the vane is curved or hooked shaped and is adapted to be presented to the interior of a building structure to provide a soft appearance.

A sectional garage door panel includes a skin part formed of a rolled metal sheet forming an outer wall and opposed top and bottom edges which may form a pinch resistant joint when adjacent panels are interconnected. Elongated prefabricated insulation parts are inserted in cavities formed by the top and bottom edges and a generally rectangular planar insulation part is insertable in a cavity formed between the top and bottom edges and between the first mentioned insulation parts. Channel shaped brackets are insertable in cavities formed by the top and bottom edges for reinforcing the skin part at a point of attachment of end stiles and hinge parts. A metal backer sheet forms an inner wall to protect the insulation parts. The brackets and one or more of the insulation parts may be secured to the skin part by an adhesive.

A connecting device rotatably joins a protective plate to a bellows that covers the guide of an automatic machine, machine tool or robot. The plate is one of a plurality of partially overlapping protective plates that slide and turn relative to each other as the bellows is extended and compressed. The connecting device includes a pushing element designed to extend freely through an aperture made in the respective plate and to come into contact with an outside face of the plate itself; a joining element which can be stably connected to the bellows at a respective transversal fold line and which is designed to come into contact with an inside face of the respective plate so as to rotatably support the plate in removable, pivot-like fashion when the plate is pushed by the pushing element; and a pair of helical springs forming a single component with the pushing element and stably connected to the joining element.

A dust cover comprises a plurality of shied plates which are equal in shape and progressively reduced in size. The shield plates are joined together such that they expand and retract along an axial direction; a linking device formed of a plurality of link rod units which have two rod members equal in length. The two rod members are pivoted together at the midpoint such that two ends of the two rod members form a pair of opening-closing arms. Two arms of each one end of each link rod unit are pivoted with two arms of other link rod unit to form two pivoting points pivoted in the lower side of the same shield plate.

The structures and process for producing the structures as shown will enable extensive and efficient use of block scrap for slat manufacturing. The techniques employed advantageously accomplish two goals simultaneously, enabling scrap, such as block scrap, to be formed into longer effective lengths. Such longer effective lengths can then be cutably formed into slats of various sizes. The joinder of the block scrap is by deeply extending, finite interlock length finger joints which, once the material is cutably formed into slats, remain as relatively shallow (the thickness of the slat) and finite interlock length finger joints. The joints have the added benefit that they statistically “break up” any grain differences which would otherwise create warp, and enable long lengths of slat to be employed from several shorter lengths of scrap. Lengths of scrap may be laterally joined before processing and as such the process and product can further salvage scrap wood narrower than the slat being produced.
摘要:
A link for rolling steel door link formed of a body and a cover plate covered on the body, the body having two short coupling tubes and a peripheral flange at one side, the cover plate having two coupling holes respectively coupled to the coupling tubes of the body and a peripheral flange abutted against the peripheral flange of the body, the end of each short coupling tube being expanded by a punch press to fixedly secure the cover plate to the body after its insertion through the respective coupling hole on the cover plate.
