Patent number: 4679371Abstract: A profile consisting of two sections (1, 2) joined together. One section (1) is an open hollow section with an inner contour which is uniform with and somewhat bigger than the outer contour of the other section (2) and where the opening (4) is arranged so that two identical profiles can be telescoped into each other. According to the invention the other section (2) is solid or a closed hollow section. The opening (4) of the open hollow section (1), has a width which is somewhat bigger than the wall thickness of the hollow section (1) in an area (5), which is situated on the opposite side relative to the opening (4) of the connection (3) between the sections (1, 2). Thus, it is achieved that the open hollow sections (1) of the profiles substantially, completely surround the other sections (2) of the profiles, respectively, when two identical profiles are telescoped into each other.Type: GrantFiled: February 2, 1984Date of Patent: July 14, 1987Assignee: Adenco Engineering ABInventor: Ann-Christin Jilken

Patent number: 4651482Abstract: A corner piece for connecting adjacent hollow spacer members to form a spacer frame used in the construction of thermally insulated windows. The corner piece includes horizontal and vertical legs forming a right angle. One end of each leg has a cutting edge. When the ends of each leg are inserted into a hollow spacer which has internal partitions, the sharpened cutting edge is able to cut around the adjacent partition and thus enter the spacer fully. The corner piece is constructed in a manner which permits sealant to be injected into the corner pieces and the spacers after assembly to seal off any gaps around the installed corner piece.Type: GrantFiled: April 10, 1985Date of Patent: March 24, 1987Inventor: Ryszard Borys

Patent number: 4648327Abstract: A locking mechanism for a mobile safe having at least one loading door for depositing valuables such as cash within the safe and at least one unloading door for emptying the safe includes an actuating mechanism for moving the loading door between its open and closed positions. The actuating mechansim extends out of the safe for engagement with a vault door locking mechanism when the safe is placed within an outer vault for secure deposit of cash into the safe. The engagement is such that the actuating mechanism operates to open the loading door as the vault door is locked. A locking device associated with the actuating mechanism automatically locks the safe door in its closed position and can only be released by subsequent unlocking or opening of the unloading door by a person having the required key.Type: GrantFiled: July 1, 1985Date of Patent: March 10, 1987Assignee: Cubic Western DataInventors: John E.

Patent number: 4640069Abstract: Apparatus and method for construction of buildings to give the appearance of full log construction. Conventional wall studs are assembled in basically a conventional manner except that the corner is assembled in an "open" manner rather than the usual "closed" assembly, so that the corner studs form a V which opens toward the outside of the building. A corner block assembly, having been pre-assembled, is then inserted into this open corner. The corner block assembly extends vertically coextensively with the height of the corner of the building. It is constructed of vertical studs and log blocks attached horizontally to these studs. The log blocks are arranged so as to alternately protrude, first from one side and then from the other, each log block being perpendicular to the block above it and the one below it and to the stud to which it attached. One side of each log block is aligned with the outer edge of the stud to which it is attached.Type: GrantFiled: April 14, 1986Date of Patent: February 3, 1987Assignee: Felser Forest Products, IncInventor: Theodore P.

Patent number: 4621475Abstract: A structural strut having at least one surface of generally U-shaped cross section and being formed with a pair of upstanding side walls having opposed tapers. The side wall tapers of the strut shift or skew the neutral axis of the member in proportion to the relative side wall dimensions. In this manner, the strut may be used to comprise a load bearing member having a neutral axis selectively slanted to a position maximizing structural loading efficiency and interconnection. The ends of the strut are further formed of substantially planar construction for flat abutment and welded attachment to cross members of a truss thereby eliminating conventional gusset plates. The structural strut may also be constructed from a pair of such U-shaped channel sections secured back-to-back with the tapering flanges complementally positioned opposite one another for selectively shifting the neutral axis of the resulting I-beam.Type: GrantFiled: August 9, 1982Date of Patent: November 11, 1986Assignee: Glitsch, Inc.Inventor: Robert W.

Patent number: 4604837Abstract: A cover member adapted to be mounted in a conventional gutter on a building structure in covering relation to the open top to the gutter trough provides a forward upwardly-extending lip portion having a curved outward surface adapted to form a dam to water runoff from the building structure to slow the speed of water runoff flowing over the lip portion to cause the overflowing water to follow the curved outward surface of the lip portion into the gutter while causing leaves and like debris to fall gravitationally over the lip portion outwardly of the gutter. In one embodiment, the lip portion is formed as an integral upwardly and rearwardly curled forward edge to the cover member. In a second embodiment, a coil spring rests between the curled lip portion and the front wall of the gutter to act as a filter against debris entering the gutter.Type: GrantFiled: September 13, 1985Date of Patent: August 12, 1986Inventor: Tony D.
