Abstract: A rolling grille having a set of horizontal bars, the bar set divided into a lower bar sub-set with a top bar and an upper bar sub-set with a bottom bar. The grille has a row of end plates on each side, the end plates joining the ends of the bars in both bar sub-sets together. Each end plate joins two adjacent bare together, each bar connected to two adjacent plates, the plates aligned when the grille closes an opening. Each end plate has a panel with an inner surface facing inwardly when the grille closes the opening. Bar mounting sections are provided at the top and bottom of each panel. At least one of the top and bottom bar mounting sections in the plates in the lower bar sub-set have a flange comber located to abut on the inner surface of the panel of an adjacent plate when the grille closes an opening. The flange member flange forms the lower bar sub-set into a relatively rigid assembly when an attempt is made to raise the lower sub-set.

Abstract: A three point pivoting 360° articulable pinchless hinge connects two members which may pivot 360° with respect to each other. The hinge has two opposing couplers, each having a toothed semicircular portion meshed with the opposing coupler toothed semicircular portion. Each coupler is adapted to be connected to one of the members to be pivoted with respect to each other. A pin is in each coupler extending along an axis of the semicircular portion thereof. A link connects each pin to maintain the meshed engagement of the couplers through 360° of coupler pivotal rotation with respect to each other. The link has a sufficient width substantially that of the width of the coupler body as to block and prevent the meshed semicircular portions from pinching an individual's finger or object. The hinge may also have a locking mechanism or detent which locks the two members at 180° from each other.

Abstract: A sectional upward-acting door, particularly adapted for use with mobile cargo containers and the like includes extruded door panels or sections which are hingedly connected to each other by hook-like hinge members integrally formed along a top edge of one section and an arcuate channel defined by a bottom wall and an integral pintle on an adjacent section. An elastomer seal and bearing member fits within the channel formed along the bottom edge of a section for engaging the hinge member and for aiding in forming a weather and light seal at the hinge joint between sections. The sections are laterally assembled by engagement of the hook-like hinge member in the channel of an adjacent section and are retained in assembly by a releasable retainer and seal member which may be formed as a co-extruded dual durometer part. Door side edge seals are insertable in a space formed between door side edge guide tracks and an inner surface of a rear wall of the cargo container.

Abstract: The opposite vertically elongated edges of a series of pivotly connected slats forming an accordion type folding shutter are provided with integral tubelike connector members. The slat integrally joins its outer member along a plane which is tangent to the outer surface of the outer member so that the extended adjacent pair of slats form a roughly ninety (90.degree.) degree angle when the shutter is extended. Thus, the forces of impact applied against the shutter is absorbed by the crushing of the outer member towards and against and then with the inner member, in engagement between the adjacent inner and outer member beads and the partial transmission of forces through the adjacent portions of the slats for resisting separation of the adjacent slats and penetration of the force applying object.

Abstract: A vehicle cab with a roof hatch (12) which comprises front and rear hatch sections (14) and (16), the rear section (14) being over an escape hatchway (26) and the front section (16) being over an equipment access hatchway (28) of a roof compartment. The front hatch section (16) is mounted on a front roof section (10a) along its forward edge by hinges (18), and releasably latched to a middle roof section (10c) along its rearward edge by secondary latches (22). The rear hatch section (14) is mounted on the rearward edge of the front hatch section (16) by hinges (20), and releasably latched to the rear roof section (10b) by a primary latch (40). The primary catch (40) may be released and the rear hatch section (14) may be partially opened and retained with rear stays (64) to provide ventilation. The rear stays (64) may then be automatically released when the rear hatch section (14) is pushed past the retention point to fully open the escape hatchway (26).

Abstract: The opposite, vertically elongated edges of a series of pivotly connected slats forming an accordion-type folding shutter are provided with integral tube-like connector members. One of the connector members is of a smaller diameter than the other to form an inner member which co-axially fits within the next adjacent outer member of the next slat. The inner members are connected to their respective slat edges by a narrow strip, extending the full length of their respective slats and arranged at an obtuse angle to the remainder of their slats, with the narrow members fitting through a slot in the adjacent outer member. The strip pivots within the slot of its outer member and engages beads integrally formed on the edges defining the slot in the outer member.

Abstract: An accordion storm shutter assembly includes a frame for installation in an opening in a building wall and a pair of folding shutters which can be drawn together across the opening. Each shutter is formed from a number of blades articulated along vertical edges so that the blades can fold flat when the shutter is open. When the shutter is closed, the blades make a substantial angle with one another, so that the shutter has a corrugated configuration for high impact resistance. Neighboring blades are interconnected by continuous extruded linear hinges, each including a socket which is substantially an arc of a cylindrical shell having a lengthwise gap, and a knuckle adapted to turn within the socket and having a blade arm extending therefrom through the gap. The shutter is intended to provide protection against winds and debris in tropical storms.

Abstract: An accordion storm shutter assembly includes a frame for installation in an opening in a building wall and at least one folding shutter supported by the frame. The shutter is made up of plural blades articulated along their vertical edges so that the shutter can fold from a closed position in which the blades made a substantial angle--about 75.degree.--with one another so as to have a corrugated configuration blocking the opening, to an open position in which the blades are substantially parallel to one another. Neighboring blades are interconnected by continuous, extruded linear hinges, each having a socket which is substantially an arc of each cylindrical shell having a vertical axis. A knuckle formed along one edge of a neighboring blade pivots in the socket.

Abstract: A plurality of plastic panels or planks (12) are connected to each other in side by side relation by interfitting male and female connectors (28, 30) to form a planar structure such as a cover (10). The male connector (28) has opposed outer planar surfaces (32, 34) in contact relation to opposed inner planar surfaces (46, 48) on a female connector (30) to minimize any relative pivoting or articulating movement between adjacent panels (12). Adjacent panel sections (15A, 17B) are hinged to each other about hinges (35E) to permit the panel sections (15A, 17B) to be folded against each other for stacking. Alternatively panels 14C, 14D may be linked together for stacking. A side support (16) is secured to the sides of the cover (10) to cover and to support a side of a panel where such side is not connected to another panel.

Abstract: Apparatus for deploying an articulated panel array comprises a spring motor between adjacent panels and a latch between adjacent panels. The latch between a given pair of panels is released by an abutment on the panel which is adjacent to the pair and toward the proximal end of the array only when the more proximally disposed panel of the pair moves to its fully deployed position. With this arrangement, only a single group of panels of the array moves at any given time providing an accurate deployment envelope.

Abstract: A graphic display panel system formed in sections, wherein a graphic display image may be affixed to each section, the sections respectively having transparent edge caps and/or hinge connectors and/or locking pin assemblies for selectively interconnecting the sections to form an overall surface. The individual panel sections may be formed of a lightweight honeycomb structure or spaced apart plastic sheets.
