<p>Various improvements to sliding panels are disclosed. In a first aspect, an elongate bottom section 6 for a sliding panel is provided, the section having an upturned U-shaped cross-section so that roller assemblies can be placed within the section at any desired position. According to a second aspect, a cover plate (11 or 12, Fig 2) for a sliding panel is provided, the cover plate fitting over an otherwise exposed structural fitting of the panel so that with the panel closed, the cover plate cannot be readily removed, thus enhancing the security aspects for interalia sliding patio doors. A frame for patio doors is provided (Fig 5) for on-site assembly from reinforced top, middle and bottom channels, upper and lower glazing panels and vertical side channels. A further improvement which is directed to providing enhanced security, comprises an adjustable height blocking mechanism (18, Fig 3) for positioning within a top retaining channel of a sliding panel assembly, the arrangement being configurable into a first configuration to allow insertion of the sliding panel between top and bottom retaining channels and then reconfigurable into a second configuration so as to limit upward movement of the sliding panel when the panel is in a closed position. <IMAGE></p> |
