Abstract: A display panel mounting unit comprising a mounting plate and at least two mounting supports. The mounting plate includes first and second support flanges having a longitudinal first member for attachment to a display panel; and a longitudinal second member attached to the first member by a pivot to provide an axis of rotation of the second member relative to the first member. The second member having a first arm on one side of the pivot and a second arm on the other side of the pivot; the first arm having an anchorage at an end remote from the pivot and a first means for retaining the mounting support on the first support flange. The second arm having, at an end remote from the pivot, a second means for retaining the mounting support on the second support flange and a compression member extends between the first member and the anchorage and resiliently biases the anchorage away from the first member.

Abstract: A stand comprising: a floor mount, a location mechanism for a unit to be supported; and at least one column extending between the floor mount to which it is attached by a first attachment and the location mechanism which is attached to, or integral with, an upper region of the or each column; the column having a longitudinal axis which is curved relative to a straight line extending between the first attachment and the location mechanism; the, or each, column serving to transmit loads applied to the stand by way of the location mechanism to the floor mount; the, or each, column comprising a hollow channel substantially symmetrical about the longitudinal axis of the front panel; the hollow spine having a cross section in the region of the floor stand which is greater than the cross section of the spine in the region of the location mechanism.

Abstract: A display panel mounting unit comprising a mounting plate and at least two mounting supports; the mounting plate, providing for the attachment of the unit to a wall or other support; and for the attachment of a display panel to the mounting plate by way of the mounting supports; the mounting plate including first and second support flanges, each, mounting support comprising: a first longitudinal member incorporating means whereby the member can be attached to a display panel for mounting; and a second longitudinal member pivotably attached to the first by means of a pivot so as to provide an axis of rotation of the second member relative to the first member; the second member comprising: a first arm on one side of the pivot and a second arm on the other side of the pivot; the first arm having at, or near, an end remote from the pivot an anchorage and a first means for retaining the mounting support on the first support flange on the mounting plate; the second arm having at, or near, an end remote from the piv

Abstract: A mounting unit (11) for a attaching a working unit such as a video projector to a mounting surface which can be horizontal or vertical or at some angle intermediate the horizontal and the vertical comprising: an anchorage (12) whereby the unit can be attached to the mounting surface; a beam (13); a carrier (18) comprising in combination a holding plate (19) and a mounting plate; the carrier being adapted to provide for the attachment of a working unit to the mounting plate; a first pivot (20a) whereby a first end of the beam is pivotably attached to the anchorage to enable the beam to pivot about a first axis (a1); a second pivot whereby the other end of the beam to the first end is pivotably attached to the holding plate to enable the holding plate to pivot about a second axis (a2) parallel to the first axis; a third pivot (24) whereby the holding plate can pivot about a third axis perpendicular to the second axis; a fourth pivot (23) whereby the holding plate can pivot about a fourth axis (a4) perpendicula

Abstract: A coupling for a modular construction system whereby a tubular element is linked to another element, or is supported, characterised by: 1) at least one cup-shaped unit (P, 22, 41, 61, 81, 102) having an open end (16) and a reduced end (12); the open end (16) serving to received an end (E) of a tubular element (T) to enable the end (E) to be pushed to a rest position (18) at the reduced end (12) of the cup-shaped Unit (P), and locking means (30) enabling a tubular element end (E) to be retained against further movement relative to the cup-shaped unit (P); the length (L') of the unit (P) being between one and one half and twice the outside diameter (D) of the tubular element (or of the major transverse dimension of the tubular element if it is of non-circular cross-section); and an aperture (13) at the reduced end (12) of the cup-shaped unit which is no more than one-half the maximum interior diameter (I) or maximum interior dimension of the cup-shaped unit (P); 2) the or each cup-shaped unit (P, 22, 41, 61, 81
