Installing the Index Clamp (or Removable Outer Piece) and Vertical Tube
Background
The Vertical Tube of the DRM1 Rigid Mount is supported in the tube hole of the UFCOP. The Index Clamp is an adjustable collar attached to the Vertical Tube which sets the height of the tube and the indexed orientation where the tube will not rotate. The Rigid Mount ROP Version DRM1ROP has a different set of components to hold the Vertical Tube.- DRM1 - Standard Rigid Mount for non-tilting seat systems
- DRM1ROP - ROP Version Rigid Mount for tilting seat systems
DRM1 - Install the Vertical Tube and Index Clamp
The Index Clamp (IC1) is installed on the lower end of the Vertical Tube with the three holes downwards. Either end of the S-bent Vertical Tube can be used as the lower end. When there are obstructions directly above the Outer Piece it will be necessary to have the shorter end of the S down. When the Vertical Tube is several inches longer than the vertical distance from the Outer Piece to the required location of the Horizontal Tube the longer end of the S will be down to allow the extra length of Vertical Tube to pass down through the Outer Piece.
Remove the plastic plug retaining the Pinch Clamp in its hole in the IC1 and insert the end of the Vertical Tube. The Pinch Clamp must be aligned in its hole so that it is even with the inside of the tube hole to allow the Vertical Tube to slide through. Tighten the bolt in the Pinch Clamp only enough to prevent the IC1 falling off when the Vertical Tube is held upright.
Setting the In-Use and Swung-Away positions of the DRM1
The tube hole in the IC1 is offset from the center of the component leaving a thick wall on one side and a thin wall on the other side. On the underside of the thick wall are three pinholes, which receive the Index Pin on the UFCOP. One pinhole will provide the in-use position of the mount, while the remaining two pins are swung-away positions. Before the Pinch Clamp is fully tightened the IC1 can be rotated around the Vertical Tube to change the orientation of the swing-away positions for the mount; the possibilities are illustrated below. The ROP Version DRM1 does not have the option of rotating away and must be fully removed from the wheelchair to gain unimpeded access to the User.
Adjust the height and S-bend orientation
To set the height of the DRM1 slide the IC1 down the Vertical Tube until the "in-use" pinhole engages the Index Pin and the IC1 is resting on the UFCOP. Lower the Vertical Tube through the tube hole in the UFCOP until the top end is at approximately the correct height for the mounted device.
Rotate the Vertical Tube within the Outer Piece tube hole until the S-bend is in the correct orientation to avoid obstructions and the top end of the tube is the correct distance front-to-back. Tighten the Pinch Clamp enough to hold the Vertical Tube firmly in place.
DRM1ROP - Install the Vertical Tube and Removable Outer Piece
The Removable Outer Piece (ROP) is installed on the lower end of the Vertical Tube oriented to match the Removable Frame Clamp Receiver (RFCR) that is connected to the wheelchair. Either end of the S-bent Vertical Tube can be used as the lower end. When there are obstructions directly above the ROP it will be necessary to have the shorter end of the S down. When the tube is several inches longer than the vertical distance from the ROP to the required location of the Horizontal Tube the longer end of the S will be down to allow the extra length of tube to pass down through the Outer Piece.
Remove the plastic plug retaining the Pinch Clamp in its hole in ROP and insert the end of the Vertical Tube. The Pinch Clamp must be aligned in its hole so that it is even with the inside of the tube hole to allow the tube to slide through. Tighten the bolt in the Pinch Clamp only enough to prevent the ROP falling off when the tube is held upright.
Adjust the height and S-bend orientation
To set the height of the DRM1ROP insert the ROP into the RFCR and lower the Vertical Tube through the tube hole in the ROP until the top end is at approximately the correct height for the mounted device.
Rotate the Vertical Tube within the Outer Piece tube hole until the S-bend is in the correct orientation to avoid obstructions and the top end of the tube is the correct distance front-to-back. Tighten the Pinch Clamp enough to hold the Vertical Tube firmly in place.
Caution:
The bolt on the Pinch Clamp should not be tightened in an extreme manner. The Pinch Clamp grips the Vertical Tube sufficient to prevent it rotating in the Index Clamp when a person pushes firmly on the Horizontal Tube but does not provide an immovable grip. Extreme tightening of the Pinch Clamp bolt on the Vertical Tube in an attempt to prevent movement when the Horizontal Tube is very strongly pushed will crush the tube and jam the Pinch Clamp. DAESSY mounting assemblies are designed to carry the weight of a computer or communication device and are not intended to resist a strong force exerted by the user.
