Abstract: A hinge on a ladder comprises outer casing pair, inner casing pair, a fixing plate with a shaft and three lock pins, a central rivet pin, and a button knob. The outer casing pair and the inner casing pair are pivotally engaged to each other in such a way that the circular plate portions on the casing pairs facially contact with one another. When the locating holes on the outer casing pair align with three specific ones of nine locating holes on the inner casing pair, the three lock pins are pushed toward the outer casing pair and to pass through the aligned locating holes and perform a locking position. When the button knob is pressed toward the outer casing pair against the restoring force of the spring, the three lock pins move away the locating holes. Therefore, the elongated projection ends of the three lock pins fit with the elongated slots on a half piece of outer casing pair to perform an unlocked position.

The contour of the coupling element (42) conforms to the internal contour of the mounting tube (12) in the region of the fastening bore (58), protrudes through openings (60) in the fastening bore (58) by a projecting length (44) and, on the inside, covers the openings (60) axially on both ends.

Abstract: A mounting mechanism for coplanar doors is of a four-bar linkage type and a door is carried on parallel links or connecting rods, so that it moves parallel to itself from a steady, closed position, through a transitory retracted or extracted position, to an opening position, before or behind another door, and vice-versa. The connecting rods are carried on a sliding carriage unit and a cam compensator unit is provided that ensures carriage movement parallel to a door plane, for part of the way, when the door is moved between its closed position and a retracted or extracted intermediate position, by rotation of the connecting rods, so that the resultant door movement is basically at right-angles to the door plane.

Abstract: The present invention relates to a closing bushing (7) which is intended for a clamping device (2) used for removably connecting two profiled parts (1). The clamping device (2) comprises an adjustment knob (6) in which a profiled part (1) can be locked and which can be inserted in a recess (5) formed in said profiled part (1). The closing bushing (7) is designed for the form-fitting reception of the clamping device (2) body through a recess (16), and comprises a bore in which the adjustment knob (6) can be received. The surface oriented in the introduction direction (12) of the clamping device (2) in the closing bushing (7) is larger than the corresponding surface of the adjustment knob (6). A clamping device provided with such a closing bushing (7) exhibits a greater resistance to the traction forces applied in the direction of the arrow (12). Clamping devices (2) of the above-mentioned type can also be used for profiled parts (1) made of materials different from the traditional ones, such as wooden parts.

Abstract: An extruded plastic sheath product is provided to cover studded steel T-posts and hence give fence lines or sign posts and improved, even aesthetic appearances. The plastic sheath product is formed with a series of internal projections which abut against features of the internal T-post and hence prevent the sheath from spinning about the T-post. For the fence line filed of use, the plastic sheath product is further given an external spine which has formations or else studs formed in it to prevent fence wire strapped to the sheath from slipping. For the sign post field of use, the sheath is further provided with a series of coupling accessories in order to construct frames and the like. Such coupling accessories optionally include Ell's, Tee's, crosses, or y-shaped splitters. The shape and arrangement of the extruded tubular sheath is especially designed to accommodate certain shape anomalies which result from the extrusion process.
