A framework has bearing members, each of which consists substantially of a wire spiral, which is stayed by means of a plurality of stiffening wires, which extend in the longitudinal or pitch direction of the spiral and are arranged around its circumference and which are securely fastened to it at mutual contact points. At each end, the bearing members are closed by an end ring. Joint elements serve to connect the ends of two or more bearing members to one another. The joint elements have the sha...

A press framework consisting of a top section, a table section and frames receiving the ends of these sections. The frames are formed of hollow columns, bridgepieces contacting the ends of the columns and stays passing through the hollow columns and bracing the bridgepieces with respect to the hollow columns.

A coupling for coupling together a plurality of elongate members, particularly members of a planar framework structure, which coupling includes a separate coupling element welded to each one of the members to be coupled together and a locking ring which is received within a groove in each of the coupling elements. A frusto-pyramidal expansion member is received within a space between the coupling elements within the locking ring and when urged further into said space forces the coupling elements...

A connector assembly connecting frame members of a frame structure having a sleeve into which an end of one frame member slidably fits. The sleeve has a plurality of longitudinally spaced buttons each of which can releasably engage a chair which receives an end portion of another frame member for connecting both frame members at right angles to each other.

A framework structure comprises longitudinal load-bearing elements and bracing elements interconnecting the load-bearing elements and intended to rigidify the structure and take up transverse forces. To this end the fastening of the bracing elements to the longitudinal elements is realized at least on one side of the structure by connections permitting a certain relative movement between the bracing elements and the longitudinal elements longitudinally of the structure. In such a framework struc...

A novel framework construction, e.g., a ladder, is provided. It includes at least two longitudinal beams disposed in substantially parallel alignment. Each beam is of a novel construction having a cross-section in the form of a pair of legs joined by a web, the web including a central area of substantially uniform thickness, and a pair of lateral areas, each such lateral area being of gradually increasing thickness in a direction away from the central area. A plurality of struts is provided, the...

A framework of a wooden building has a pair of vertically extending pillars formed on opposite sides thereof with longitudinal grooves and a wall panel mounted between the pillars, having its side edges inserted in the grooves in the pillars. A diagonal pillar formed in the opposite sides thereof with grooves may be provided between the vertical pillars to support two triangular wall panels. A fitting such as a window sash may be mounted between the pillars so as to be sandwiched between upper a...

Extendible support frameworks having the ability to contract from an extended position into a collapsed position wherein the upper mounting plate is lowered and laterally displaced with respect to the lower mounting plate. The frameworks include at least one articulated leg having a first part and a second part joined by an articulation pivot. The first part of the articulated leg is pivotally connected to the upper mounting plate. The second part of the articulated leg is pivotally connected to...

A framework for supporting the glass panels of a skylight is formed of spacedrafters inter-connected by cross bars. The rafters have upstanding side flanges provided with pairs of transverse slots. The ends of the cross bars have pairs of outwardly extending headed members adapted to be engaged in the slots to locate the cross bars. The rafters have a ledge below each side flange upon which the bottom of a cross bar can rest. The cross bars are locked in place on the rafters by extending a pin f...

Framework for electrical components comprises a metal plate with insulated major surfaces and conductor patterns on opposite sides thereof. Synthetic resin mounting projections are secured to plate by resin passing through holes. Synthetic resin eyelets in holes may be plated to electrically connect conductor patterns on opposite sides.
