Definitions

  • the present invention relates to a mounting bracket for attaching a flat screen monitor support arm to a wall or partition panel having at least a pair of spaced parallel channels formed therein.
  • the invention relates to a mounting bracket having means for securely attaching it to the surface of a wall or partition panel.
  • Flat screen computer monitors are now in widespread use and have the advantage of being relatively light and slim, which enables them to be mounted on one end of an elevated and adjustable support arm. It is conventional for the other end of the support arm to be attached to a post upstanding from a work surface, such as a desk or table. However, it is also becoming common for one end of the monitor support arm to extend from a mounting bracket which attaches to a desk partition panel or wall plate and in which is formed at least a pair of spaced parallel channels extending in an horizontal direction across the width of the panel. Walls or partitions having this construction are well known in the industry and are often referred to as "slat-wall". The channels formed in the slat-wall are commonly used to attach a number of other work related items such as shelves, lights and stationary holders, and is convenient because it enables them to be removed or repositioned easily.
  • a problem with the conventional mounting brackets for attaching a monitor support to a wall or partition panel of the type mentioned above is that they are difficult to attach and release easily and quickly. Furthermore, this means that it is difficult to adjust the position of the monitor relative to the wall or partition panel. Additionally, the connection between the bracket and the wall or partition may not be particularly firm and may work loose over time which means that it has to be tightened on a periodic basis, especially if the position of the monitor needs to be adjusted regularly. Occasionally, it is desirable to slide the slat-wall bracket in a horizontal direction along the slat-wall into a new position without physically detaching it altogether from the slat-wall or, removing the monitor support post and monitor mounted to it.
  • the present invention seeks to provide a monitor support bracket that overcomes or substantially alleviates the problems with conventional monitor support brackets referred to above.

Lateral edges 82 of the rear portion 77 locate in the guide slots 42 so that the locating bracket 69 is constrained to a sliding movement along the rear face 41c of the axially extending aperture 41 in a direction defined by the guide slots 42.
  • the operating shaft 48 extends through the operating shaft passage 47 and the cylindrical portion 70 of the operating shaft 48 is supported by the first and second openings 44,45 such that the operating shaft 48 is rotatable about it's longitudinal axis.
  • the cam portion 72 of the operating shaft 48 extends from the first opening 44 such that it is disposed in the axially extending aperture 41 and extends through the rear portion of the locating bracket 69.
  • the cam portion 72 is received through the first section 80 of the aperture formed in the locating bracket 69 and the edges 81a of the aperture second section 81 subsequently locate in the circumferential recess 76. Therefore, movement of the operating shaft 48 along its axis is prevented as the lateral edges 82 of the locating bracket 69 are disposed in the guide slots 42.
  • a spring 83 is disposed in each circular aperture 37 between the fixed and movable clamping plates 56,57 such that one end of each spring 83 is seated in the respective cut outs 65a of the fixed clamping plate 56 and the distal end thereof against an opposing edge 84 of the movable clamping plate 57 to urge the movable clamping plate 57 away from the fixed clamping plate 56.
  • the operating shaft 48 extends laterally thereto such that the perpendicular portion 78 of the locating bracket 69 is disposed between the faces 73,74,75 of the cam portion 72 and the end of the shaft 58 distal to the tool engaging end face 59. Furthermore, this limits the movement of the movable clamping plate 57 as will be explained hereinafter, the tool engaging face 71 of the operating shaft 48 is accessible through the second opening 45.
  • the end plates 39 are affixed to the body 31 by screws 40 which extend through the end plates 39 and engage with the threaded sections 38 of respective circular apertures 37.
  • each engaging rod 53 extends from the panel engaging faces 34a,34b such that, when the body 31 is located against the panel 2, the body may be securely fastened thereagainst due to the resilience of the engaging rods 53.
  • the mounting bracket 1 is thereby fixedly attached to the panel 31.
  • the operating shaft 48 is rotated by, for example, an alien key engaged with the tool engaging face of the operating shaft 48 into a "repositioning" position indicated by the relevant markings (not shown).
  • the cam portion 72 is rotated such that the first planar face 73 of the cam portion 72 is moved into contact with the perpendicular portion 78 of the locating bracket 69.
  • rotation of the operating shaft 48 causes linear motion of the shaft 58 and hence the movable clamping plate 56 such that said movable clamping plate 56 is moved away from the fixed clamping plate 56 by a predetermined distance so that the position of the mounting bracket 1 on the panel 2 may be adjusted without removing the mounting bracket 1 from the panel 2.
  • the predetermined distance is a distance which is sufficient to release the grip of the clamping plates against the slat wall so as to enable the bracket to be slid along the channel in which the clamping plates are located.
  • the predetermined distance is insufficient to allow the clamping plates to exit from the channels in which they are located.
  • Removal of the mounting bracket 1 from the panel 2 is achieved by either rotating the shaft 58 in the opposite direction thereby disengaging the hooked edge portions 56a,57a from the channels 8 as disclosed in the first embodiment.
  • a quick release function is provided by rotating the operating shaft 48 into a 'removal' position, as indicated by the respective markings (not shown).
  • the operating shaft 48 is rotated such that the second planar face 74 of the cam portion 72 is in contact with the perpendicular portion 78 of the locating bracket 69, the second planar face 74 having a shorter distance between its bisector and the longitudinal axis of the operating shaft 48 than the first planar face 73.
  • the shaft 58 and movable clamping plate 57 move in a direction away from the fixed clamping plate 56 such that the distance between the hooked edge portions 56a,57a increases and they are disengaged from the channels 8 in the panel 2.
  • the bracket may also be reattached to the slatwall by inserting the clamping plates 56,57 into the channels and rotating the shaft 48 back into its locked position.
  • the shaft 48 need only be turned through a short angle, approximately 35 degrees to quickly release the clamping members from the channels and enable the bracket to be removed from the slatwall. This method of removal is therefore quicker than rotating the shaft 58 to release the clamping members.
