Abstract: A molding assembly having a hanger member fixedly securable to an inner or outer wall of a building and a decorative molding insert member releasably engageable with the hanger member. The molding insert member is supported at a lower edge portion by a lower J-channel of the hanger member. An upper L-shaped portion of the insert member is supported by a depending lip portion of the hanger member which forms a second channel such that no external fastening elements are required to secure the molding insert member to the hanger member. The insert member can be quickly and easily releasably engaged within the J-channel and the second channel without the need for special tools. In an alternative preferred embodiment the insert member includes a lip portion which is adapted to slidably engage an under surface of an adjacently positioned insert member to provide an even more continuous appearance for adjacently positioned insert members.

The covering material is greater in width than the sum of the widths of the top and two side surfaces, so that the edges of the formed covering material extend beyond the mineral fiber core.

Abstract: An improved arm piece assembly for a crutch comprising a hollow, thermoplastic blow-molded arm piece and an outer resilient covering molded to the outer surface of the arm piece. The inner side surface of the arm piece is located at a slight angle to the vertical, and is generally concave in the horizontal direction to more readily accommodate the ribcage of the user. The bottom surface of the end piece is provided with a pair of recesses which receive the ends of the bows of the crutch. The recesses are reinforced by depressions that are formed in the side surfaces of the end piece adjacent the recesses. The bow ends are locked within the recesses by fasteners such as spiral nails, which are driven through the depressions in the side surfaces of the end piece into engagement with the bow ends.

Abstract: In a light-tight enclosure, elongate members and joint connectors are joined to one another to form a framework to which panels having projecting ribs with right-angled corners are mounted. Each elongate member is extruded from aluminum so as to have open ended grooves. Each joint connector is fabricated from aluminum so as to have open ended grooves, some of which have right-angled corners conforming to right-angled corners of the projecting ribs. At each joint where elongate members and a joint connector are joined, the open-ended grooves merge with one another so as to define continuously extending grooves receiving the projecting ribs of the panels mounted to the framework at the joint. Some joint connectors are employed as corner connectors while other joint connectors are employed as edge connectors.

Abstract: A multi-function support device to assist the mobility of people having minor to extreme handicaps includes an elongate main shaft having a plurality of telescoping tube sections axially movable relative to one another throughout a range of selected, locked positions to enable adjustment of an overall length of the device.

Abstract: A method and apparatus for the construction of a two-layer flooring system for use at a construction site such as an oil well drilling site. The flooring system is particularly well suited for use in areas with dry, sandy soil. The flooring system is formed by interlocking both the ends and sides of a plurality of mat units. Each of the mat units includes two layers of boards. The first layer has end locking tabs extending beyond the edge of the first layer and corresponding end locking slots, formed by offsetting selected boards. The second layer similarly includes side locking tabs and corresponding side locking slots, also formed by offsetting selected boards. The arrangements of these tabs and slots is such that half-size units and inverted units may be utilized, allowing a wide variety of patterns of interlocking units to be utilized for the flooring system.

Abstract: Water is prevented from entering the wall interior of a building from in and around a wall component, such as a window, mounted in the building wall, by positioning a diverter directly beneath the wall component. The diverter includes an upper surface that slopes toward the wall exterior, a plurality of spaced, parallel ribs extending upwardly from the upper surface and beyond the exterior wall to form a plurality of downwardly sloping channels, a cover over the outer ends of the ribs to form drainage openings at the ends of the channels, and filters in the channels to prevent water from entering the wall interior through the channels.

Abstract: A collapsible tent including a closed loop resilient coilable member, the member being distorted to form at least three support loops. Each support loop adjoins the other support loops along a single portion of its perimeter with the support loops having a common adjoining region. Each support loop has a perimeter substantially the same as that of the other support loops and a membrane attached to the perimeter of the support loop. The membrane extends between the opposing portions of the support loop to restrain the support loop. The tent further includes a base membrane attached to the perimeters of the support loops and extending between the support loops to restrain the support loops in relation to one another. When the tent is expanded, the support loops are in spaced relation to one another around the common adjoining region and are restrained by the membranes. The common adjoining region forms an apex of the tent and the membranes define walls and a base of the tent.

In their sides, facing the interior (14) of the room, the profiles are formed substantially parallel with the wall extending flanges (8) against which the wall panel is arranged from the outside, as seen from the interior of the room. Fastening mechanisms (12) are arranged at the outside of the wall panel for fastening of the panel to the profile flange members.

Abstract: A brick veneer anchor for use in the construction of wall structures is described. The anchor has an L-shaped plate for attachment to a dry wall installation. The L-shaped plate attaches to the outer surface of the inner wythe and has a portion thereof extending beyond an insulative layer into and terminating within the cavity between the inner and outer wythes. An elongated slot in the dry wall anchor accepts a bent stay with one end interlocking with the elongated slot portion and the other end embedded within the outer wythe. The bent stay has a T-head portion with a length greater than the longitudinal axis of the slot. The bent stay also has a neck portion attached to T-head portion which forms shoulders on either side of the T-head portion. The dry wall anchor, upon attachment to the inner wythe, has one end of the bent stay inserted into the elongated slot and the other end of the bent stay embedded in the outer wythe.

Abstract: A slip-resistant floor covering system comprising, in accordance with preferred embodiments of apparatus of the present invention, a slip-resistant tile having a plurality of pyramidal-shaped ridges which support an individual's foot at an elevation above liquid and other slip-inducing substances which flow through a network of drainage troughs (each trough being defined between adjacent ridges) and channels in the upper surface of the tile. The ridges of the plurality of ridges are directionally oriented relative to the channels to encourage rapid flow of spilled liquid and other substances away from a spill site. The orientation of the ridges relative to the channels also induces air flow through the troughs and channels in order to reduce foot and leg fatigue which may be experienced by an individual standing on the tile for long periods of time. Protruding members, extending from the lower surface of the tile, contact a floor surface and limit relative movement between the tile and the floor surface.

Abstract: A graffiti protected glass window for a vehicle can be quickly refurbished by changing a thin plastic guard window overlying the glass pane. The plastic guard window is retained within a resilient elastomeric mount which also retains the glass pane within the rigid window frame. A window guard seating space is defined along one side in a upper portion of the seating space defined in the mount for accommodating the glass pane. The side of the mount into which the window guard seating space is defined is molded so as to be slightly inwardly inclined to assist in weather sealing the window guard. The mount is selectively locked and unlocked by the use of a conventional locking channel and locking strip. The window guard is easily removed and reinserted using conventional hand tools.
