Definitions

  • This invention relates to clamps for use on tables and desks, in particular clamps for attachment to a desktop for anchoring an arm adapted to carry a variety of devices including lamps, support brackets, trays and computer monitor screens.
  • CTR cathode ray tube
  • the present invention is a clamp for anchoring a support member to a desk or table including:
  • first planar member is capable of being inserted into a gap between a wall or partition and a desk so that when fully inserted, the underside of the second planar member sits on top of the desk.
  • the topside of the second planar member includes the actuator and the support member mounting means.
  • the clamping member is able to move along the longitudinal direction of the first planar member when the actuator is operated by a user, and it is substantially flush with the first planar member's inner face when the clamp is in its fully open condition.
  • the clamping member moves towards the second planar member, and this movement causes the clamping member to extend from its flushnes* with the inner face of the slidable member, and the clamping member continues to extend outward until it reaches its fully extended position as it continues to approach the second planar member.
  • the clamping member makes contact with the underside of the desk, and when sufficient force is applied to the actuator, the L shaped body is clamped to the desk by the clamping action between the underside of the second planar member and the clamping member upon the desk. Once clamped, the mounting means is ready to be used.
  • the clamp includes a cam lock that is movable between a locked and unlocked position, and when it is moved from the unlocked position to the locked position, it forces the clamping member in the direction towards the desk, thereby increasing the clamping force upon the desk.
  • a cam lock that is movable between a locked and unlocked position, and when it is moved from the unlocked position to the locked position, it forces the clamping member in the direction towards the desk, thereby increasing the clamping force upon the desk.
  • the cam lock is attached to a lever that is pivotally attached to the second planar member, and when it is swung up and away from the top of the second planar member, it is in the unlocked position, and when it is swung down upon the second planar member, it is in the locked position.
  • the lever is in the form of a cover that when it is in the open unlocked position, the actuator is exposed and operable by a user, and when it is swung into the locked position, the cover overlays the actuator, thereby fully engaging the clamp upon the desk, and preventing accidental operation of the actuator.
  • the first planar member includes a slidable member that sits substantially flush with the inner face of the first planar member, and is capable of sliding along the longitudinal direction of the first planar member under the influence of the actuator, and the clamping member is attached to, and contained within, the slidable member.
  • the clamping member sits flush with the slidable member when the clamp is in the fully open condition.
  • the clamp is in the fully open condition when the slidable member is located furthest away from the second planar member.
  • the clamping member is pivotally attached to the slidable member, and is able to rotate about the pivot out from the inner face of the first planar member as the slidable member is slid up towards the second planar member.
  • the clamping member is forced to pivot out from its retracted position flush with the slidable member, and as the slidable member continues to move up towards the underside of the desk, the clamping member continues to pivot out until it reaches its maximum extension out from the slidable member, and from then on it is carried by the slidable member in the fully extended position as the slidable member continues to move up towards the underside of the desk.
  • the clamping member is forced to swing out from the slidable member by a pivot control arm that is pivotally connected to the opposite end of the slidable member from the pivot point of the clamping member.
  • the control arm is rotatably attached to the clamping member such that when the slidable member moves in a direction towards the second planar member, a compressive force is applied in the longitudinal direction of the first planar member between the pivot point of the control arm and the pivot point of the clamping member. This causes both the pivot control arm and the clamping member to extend out from their respective fiushness with the slidable member.
  • the clamping member is forced to swing out from the slidable member by a pivot control arm that is pivotally connected to the opposite end of the slidable member from the pivot point of the clamping member, and is rotatably attached to the clamping member such that when the slidable member moves in a direction towards the second planar member, a compressive force is applied in the longitudinal direction of the first planar member between the pivot point of the control arm and the pivot . point of the clamping member, thereby causing both the pivot control arm and the clamping member to extend out from their respective flushness with the slidable member.
  • the clamping member is spring biased so that it normally extends outwardly from the inner face of the first planar member.
  • the rear of the desk forces the clamping member to retract back until it sits substantially flush with the inner face of the first planar member. This causes the clamping member to push against the spring bias.
  • the spring bias forces the clamping member to spring back out into its normally extended position away from the inner face of the first planar member, thereby enabling it to engage with the underside of the desk when the actuator is used to operate the clamp.
  • the clamp is fully engaged when the slidable member has been moved sufficiently up towards the underside of the desk by the operation of the actuator so that the fully extended clamping member engages with the underside of the desk and clamps the desk between the clamping member and the inner face of the second planar member.
  • the actuator is a disc that is capable of being rotated like a dial.
  • the actuator interengages with a shaft that is included in the said first planar member.
  • the shaft extends in a longitudinal direction and has an external screw thread. Rotations of the actuator by an operator causes corresponding rotations of the shaft which in turn causes the slidable clamping member to move in the longitudinal direction of the first planar member.
  • a cover member is placed over the actuator to prevent accidental operation of the actuator.
  • the cover member is pivotally attached to the L shaped body and is capable of being swung out of the way when the actuator is being operated, and can be swing back into its rest position overlaying the actuator when the actuator is not being used.
  • the actuator is dimensioned relative to the shaft such mat it is relatively easy to turn the actuator by a user.
  • the shaft is designed such that only a small number of turns of the actuator is needed to force the clamping member to move upwards and engage with the underside of the desk.
  • Figures 1 and 2 are an isometric view of the clamp assembly with the clamp in the full retracted, position
  • Figures 3 and 4 are an isometric view of the clamp assembly with the clamp in the fully extended position. (Note that desk is not shown)
  • Figures 5 shows an isometric view of the clamp assembly with the lever action cover member in the up position, and a cutaway section showing the features of the cover member that provide the final clamping force to the clamp when the cover member is swung down to overlay the actuator. (Note that desk is not shown)
  • Figures 6 is a side view of Figure 5.
  • Figure 7 shows the cover member being moved from its upright position to its overlaid position.
  • Figure 8 shows the cover member in the overlaid position.
  • Figure 9 is a side view of Figure 8 with a cut-away section showing how the lever action of the cover member imposes an additional clamping force onto the desk.
  • a clamp 1 having a substantially L shaped body comprising a first planar member 3 and second planar member 5.
  • the first planar member 3 is dimensioned so that it is capable of being inserted in a gap between a partition or a wall, and a desk that has been placed adjacent to it The first planar member 3 is inserted into the gap until the underside 7 of the second planar member rests upon the top of the desk.
  • the first planar member 3 includes a slidable member 13 which rests substantially flush with the inner face of the first planar member 3 when the clamp 1 is in the fully open condition.
  • the slidable member carries a clamping member IS which also sits flush with the inner face of the first planar member 3 and the slidable member 13 when the clamp is in the fully open condition.
  • the actuator cover member 9 has been swung out of the way, thereby exposing the actuator 11, which is in the form of a disk.
  • Cover member 9 is hingedly connected to the second planar member S. Swinging the cover member out to its fully open position as shown in Figures 3 and 4 causes a cam lock to fully disengage.
  • the actuator 11 has a depression or hole to allow an operator to get a grip on the actuator and rotate it.
  • Figures 5 and 6 show the clamping member IS fully extended. As the actuator is rotated, the upper end of the clamping member 15 eventually makes contact with the underside of the desk. It is not possible or practical to impose a maximum clamping force by using the actuator alone. As can best be seen in Figure 6, by having a actuator cover member 15 in the up position, a gap 29 is created between the underside of the second planar member 5.
  • FIGs 8 and 9 show the clamp fully engaged with the desk 17.
  • a shaft member 21 is located in the first planar member 3. Rotations of the actuator 11 cause a corresponding rotation in the shaft 21.
  • the actuator can only be operator when the actuator cover member 9 is swung into its upright postion, thereby allowing access to the actuator.
  • the actuator When the actuator is rotated, it imposes a force on the top 31 shaft member 21.
  • Rotatiuons of the actuator 11 causes the shaft to rotate in the opposite direction.
  • Rotations of the shaft 21 in one direction causes the slidable member 13 to be driven upwards towards the second planar member by its engagement with the screw thread on the shaft 21. Rotation of the shaft in the opposite direction causes the slidable member to move down.
  • the cover member 9 is levered down to its normal locked position overlaying the actuator to prevent any accidental operation of the actuator. This lever action operates the cam lock 31.
  • the support member 19 is then ready to receive a support arm that is capable of carrying various items such as flatscreen monitors and desk lamps etc.
