A ski training apparatus is provided that simulate movement similar to alpine skiing. A pivoting arm is mounted at the base of the front vertical post and carries a parallelogram linkage assembly, with two flanged wheels mounted on the linkage assembly. A guide swivel is mounted on the floor base underneath the flanged wheels. Two horizontal and parallel foot platforms are mounted on the linkage assembly for rocking motion about vertical parallel axes. The pivoting arm, foot platforms, flanged wheels and guiding swivel constitute a low friction mechanism that provides the compound motion similar to that of alpine skiing. A holding bar and a padded lower back rest will maintain the body properly positioned.

A fire-resistant wall structure is provided with a recessed corner guard, for absorbing impact forces, particularly at an external corner. To compensate for the relative loss of fire-resistance capability, in the area in which the wall structure is recessed to receive the corner guard structure, surfaces within the recess are provided with a layer of intumescent paint which, when exposed to sufficiently elevated temperature, expands to develop a thick, cellular foam providing a highly effective insulating layer. The intumescent paint is applied directly to surfaces of an extruded aluminum structural element installed in the recess. Preferably, the paint is applied at the factory where the corner guard components are manufactured. Significant economies and other benefits are realized in relation to prior practices of installing ceramic matting in the wall recess at the construction site.

A multi-functional, universal guide rail member is provided, for incorporation in an architectural joint system. Typically, one such guide rail member is mounted on each of two adjacent, relatively movable structures and cooperates with pivotally mounted centering bars to maintain a covering plate in centered position. The guide rail member incorporates in a single, integral unit a continuous guide groove for the centering bars, an open-sided slot for receiving fastening means (or, in some cases, caulking), and an outwardly facing slot for receiving anchoring means. The multi-functional guide rail member is usefully employed in conjunction with standard off-the-shelf structural components, such as channels and angle members, to accommodate mounting of the guide rail members in a variety of architectural configurations. In some architectural joint systems the multi-functional guide rail members may be employed in a manner making use of less than all of their functions, adding to the universality and economy of the system.

Multi-functional universal member for architectural joint systems

An architectural joint system is disclosed, which incorporates a slidably supported arched cover plate to span the open space between two relatively movable structural units. The edge margins of the arched cover plate are slidably received in housings, mounted at the adjacent corners of the structural units. The housing assemblies are formed of base members and cover members assembled to define a narrow gap for the reception of a thin cover plate, and an enclosure for receiving the edges of the plate. The cover members are uniquely designed to have an outwardly and upwardly convergent taper, extending over a substantial distance of at least about two times the thickness of the cover member. The arched plate is of a shallow, upwardly convex contour, closely conforming to the long convergent taper of the cover member. The new construction is a significant improvement over known arched cover type joint systems, in that it presents a substantially inconsequential deviation from a flat, planar surface of the adjacent structures, an important advantage in the construction of floors for hospitals and similar institutions.

A fire-resistant wall structure is provided with a recessed corner guard, for absorbing impact forces, particularly at an external corner. To compensate for the relative loss of fire-resistance capability, in the area in which the wall structure is recessed to receive the corner guard structure, surfaces within the recess are provided with a layer of intumescent paint which, when exposed to sufficiently elevated temperature, expands to develop a thick, cellular foam providing a highly effective insulating layer. The intumescent paint can be applied to surfaces of the recess itself, and/or surfaces of the corner guard assembly installed in the recess. In the latter case, the paint can be applied at the factory where the corner guard components are manufactured. Significant benefits are realized in relation to prior practices of installing ceramic matting in the wall recess at the construction site.

An elastomeric joint seal for architectural structures is provided with a multi-part cover and employs special anchoring hardware at least partially, and preferably entirely, mounted outside of the joint. The preferred mounting hardware comprises channels for receiving anchoring ribs of the multi-part cover. The main portion of the cover spans and seals the architectural joint, and is secured in the mounting hardware by anchoring ribs at each side. Cover strips are also anchored in the mounting hardware, and cover any exposed portions of the mounting hardware. The effective width of the joint is increased, by locating the mounting hardware outside of the joint space, which enables the joint to be designed to a narrower width dimension. The cover strips may be of a different color than the main seal to minimize the sight line. Significant economies are realized in the manufacture and installation, in part because the multi-part cover construction enables smaller and therefore less expensive extrusion equipment to be employed, and in part because the traditional difficulties involved in preparing the joint faces and in installing the mounting hardware within the joint space are avoided.

Elastomeric seismic seal system

A telescoping wall joint system is disclosed, for connecting adjacent sections of an architectural structure, while accommodating substantial relative movement, such as might result from seismic activity Extended motion is provided in the joint system while avoiding the use of excessively wide components, which are both costly and aesthetically undesirable. A center cover plate, which spans the open space between two adjacent structural units, is received along one or both sides in a tubular sleeve. The cover plate is slidably extendable within a predetermined range in the tubular sleeves to accommodate normal movements of the structural units, such as may result from thermal expansion and contraction, for example. The tubular sleeves themselves are slidably received within fixed housings mounted on the respective structural units. When the separating movement of two adjacent structural units becomes so great that the cover plate reaches a limit condition in its slidable extension out of the tubular sleeves, the sleeves themselves slidably extend in relation to the housings in which they are carried. The capacity of the system to accommodate separating movement of the structures is thus greatly increased.

Telescoping wall joint system, especially for seismic applications

An elastomeric seal for connecting two relatively movable architectural structures, such as floor sections, is constructed to optimize resistance to failure of the elastomeric element, in either adhesion or cohesion modes. An elastomeric seal, and an underlying support plate are provided with gently undulating, somewhat sinusoidal surface configuration, with the elastomeric element being of downwardly convex configuration and of relatively maximum thickness in its center, and of downwardly concave configuration and relatively less thickness in regions spaced on either side of center. Widthwise stretching of the elastomeric element tends to be concentrated in the regions of downwardly concave configuration, being thus not only distributed but also located away from areas of maximum vertical stress. An underlying supporting plate is provided with relatively thin, deformable edge flanges, which enable the supporting plate to function as a mold bottom, for pouring of a curable liquid elastomer at a nominal width, while at the same time allowing lateral compression of the assembly to a lesser width during normal functioning of the sealing system.

Elastomeric sealing system for architectural joints

The present invention is directed to architectural joint systems, and particularly to an improved multi-functional cover device, arranged to span the gap between two adjacent, spaced apart architectural structures, such as walls or ceilings. The cover system comprisies a multi-functional cover plate element can be secured by a variety of means.

Multi-functional wall cover for architectural joints

A one-piece molded or cast centering bar, for an architectural joint system, is disclosed. The centering bar, which is designed for cooperation with spaced guide rails, mounted on opposed, relatively moveable structures, has a central base section and integral arm portions extending radially therefrom in opposite directions. Integral guide means are carried at the outer ends of the respective arm portions, and engage guide grooves in the respective guide rails. The centering bar is pivotally connected to a cover plate, which spans the space between the moveable structures. As the structures move toward and away from each other, the centering bar functions in a known manner to maintain the cover plate symmetrically positioned with respect to the open space.

Centering bar for architectural joint systems

An improved fire barrier system is disclosed for interposition within an expansion joint between adjacent wall or floor members. In the disclosed embodiment, the invention is characterized in that the fire barrier system is symmetrical in both pairs of opposing quadrants defined by a first axis parallel to and midway between said mutually facing walls and transverse to said direction of elongation and a second axis transverse to said first axis and to said direction of elongation. This symmetry affords equal resistance to fire from either side of the barrier, eliminates the possibility of the joint being installed backwards, and permits the barrier system to be fire-rated for resistance to fire from either side of the barrier on the basis of a single test.

Fire barrier system

An end cap is disclosed for terminating the end of a joint cover for sealing an elongated expansion joint between adjacent dynamic structures in such a manner as to permit movement of the joint while sealing the end of the joint against water and debris. The end cap includes an elongated convex elastomeric cover having portions thereon attached to each of the adjacent dynamic structures such that the convex cover spans the expansion joint between the adjacent structures to seal the joint. The end cap further comprises a transverse end wall member transverse to the direction of elongation of the expansion joint. The transverse wall member has at least one pleat formed therein transverse to the direction of movement of the joint, such that the transverse wall member folds and unfolds along the pleat as the expansion joint closes and opens.

End cap for expansion joint

An end dam nosing material useful for expansion joints and having high levels of bonding strength, tensile strength, compressive strength, flexural capabilities, resiliency, and resistance to chemical action is disclosed. The end dam nosing material of the present invention does not require the addition of external heat for curing. The end dam nosing material of the present invention comprises a mixture of a dipolymerized elastomer, an epoxy resin, a filler material and an amount of a curing agent effective to cure the epoxy resin and generate sufficient heat to cure the dipolymerized elastomer.
