Installing the DAESSY Rear Folding Mount - DRFM6
Install the Frame Clamp Assembly, Rear Folding Adapter and Side Tube
Background
The DAESSY Rear Folding Mount - DRFM6 can be mounted on either the left or right side of a wheelchair as defined from the position of the person seated in the wheelchair.
Find the location on the wheelchair to attach the Frame Clamp. This should have been chosen already in the Selecting a Frame Clamp Location step of the Fitting Procedure. The Rear Folding Adapter will be positioned partway down the side of the wheelchair and 2 to 5 inches below the seat base and connected to the Frame Clamp Inner Piece with Offset Links if necessary. The selected location must be part of the wheelchair frame not a movable armrest or footrest.
It does not matter how the wheelchair frame tube is oriented because the Swivel Clamp allows the Rear Folding Adapter to be rotated to any angle relative to the Frame Clamp Inner Piece.
Assemble the Frame Clamp Pieces
The pieces of the Frame Clamp Assembly must be connected together before the Frame Clamp is installed on the wheelchair frame. These pieces will include a Frame Clamp Inner Piece or Removable Frame Clamp Insert (RFCI), a Rear Folding Adapter (RFA), and any additional Offset Links and/or Frame Clamp Spacers.
When the Inner Piece has a Cap and Body fastened with two screws, the Cap must be removed so that the threaded end of the Swivel Clamp can be fitted in the long hole through the Inner Piece. Some Inner Pieces have integrated threaded holes for the Swivel Clamp bolts and do not use the threaded end.
If the mount assembly requires a Bolt-on Adapter (for example the MH3/IPA) this component should be installed on the wheelchair first, as the installation bolts may be inaccessible once the complete Frame Clamp Assembly has been assembled. The remaining pieces of the Frame Clamp Assembly will be connected together and finally bolted to the Inner Piece Adapter that has been pre-installed on the wheelchair.
The adjoining faces of all the parts for a Frame Clamp Assembly have circular grooves to give extra friction against movement when assembled. The grooves on an Inner Piece engage with the grooves on an Outer Piece but will not engage with the grooves on another Inner Piece. Offset Links and Frame Clamp Spacers have the letters IP stamped into the metal beside the grooves that attach to the Inner Piece and OP stamped into the metal beside the grooves that attach to the Outer Piece.
Caution:
All the grooved faces must be correctly matched and engaged before the Swivel Clamp bolts are tightened.
When one O3L is used to connect the Inner Piece and the RFA the unthreaded end of each Swivel Clamp is inserted into the holes in either end of the O3L. When more Offset Links are needed to correctly position the RFA, the IP end of one O3L is connected to the OP end of another with a Swivel Clamp. It is convenient to orient the Swivel Clamps so that the bolt heads are accessible from the outside of the wheelchair.
When a Frame Clamp Spacer (UFCSPCR) is needed to gain extra clearance away from the wheelchair frame it can be placed between any connection of the grooved faces, taking care to mate the IP and OP surfaces correctly. Longer Swivel Clamp bolts are provided with the UFCSPCR.
Note:
Offset Links displaying Serial Numbers greater than #406000 may be connected directly together or connected directly to the Rear Folding Adapter at any angle.
Offset Links that display a Serial Number less than #406000 or have no Serial Number must not be connected together or to the Rear Folding Adapter at an angle of less than 135º.
Two Offset Links connected with an intervening Frame Clamp Spacer can be connected at any angle. The Swivel Clamp connecting through the Spacer will require longer bolts.
The pieces of the complete Frame Clamp Assembly should be assembled and the Swivel Clamps moderately tightened to hold the unit in approximately the correct orientation before attaching the Frame Clamp Inner Piece to the wheelchair.
Remove the Stop Pins from the Rear Folding Adapter
On one side of the Rear Folding Adapter is a Screw-on Cover retained by a Locking Nut. Remove this nut and cover to access the Stop Pins. There is a hole in the rim of the Screw-on Cover that allows an Allen Key to be used as a lever to assist removal. The Stop Pins are removed at this step, however they must be reinstalled and the Screw-on Cover and Locking Nut replaced before a device is attached to the mount.
Attach and Align the Frame Clamp
There are three steps to attaching and aligning the Frame Clamp Assembly:
- Attach the Inner Piece and Position the Rear Folding Adapter
- Install the Side Tube into the Tube Mount of the Rear Folding Adapter
- Align the mount sideways
Attach the Frame Clamp Inner Piece and Position the Rear Folding Adapter
At the selected location fit the Cap and Body of the Frame Clamp Inner Piece around the tube. Replace the bolts but do not fully tighten them yet. The Cap should face towards the inside of the wheelchair and the Body, connected to the Offset Link, should face towards the outside.
Position the Rear Folding Adapter (RFA) at the chosen location midway down the side of the wheelchair and slightly below the seat level. Gently tighten the bolts on all the Swivel Clamps. These bolts may need to be loosened during the final adjustment of the mount location.
The Removable Frame Clamp Insert and Removable Frame Clamp Receiver (RFCI-RFCR) can be installed between the Frame Clamp Inner Piece and the first Offset Link to allow the entire Rear Folding Mount and outer components of the Frame Clamp Assembly to be easily removed from the wheelchair.
The latch of the RFCR can be oriented in any direction for access.
Install the Side Tube into the Tube Mount of the Rear Folding Adapter
Remove the plastic plug holding the Pinch Clamp in its hole in the Tube Mount (RTHTM) on the RFA. Check the alignment of the Pinch Clamp inside the tube hole and insert the Side Tube. Tighten the Pinch Clamp bolt.
If the Frame Clamp Inner Piece (UFCxxxxIP) is attached to round tubing on the wheelchair the Side Tube will need to be aligned sideways. Use the Side Tube as a lever to move the UFCxxxxIP until the Side Tube is aligned parallel with the side of the wheelchair.
Check that the Side Tube can be rotated between the In-use and Folded positions without contacting any part of the wheelchair.
Caution:
With the Stop Pins removed from the Rear Folding Adapter the Side Tube will rotate past the In-use and Folded positions. The Stop Pins must be replaced before any device is attached to the mount.
If the Side Tube does contact the armrest or any other part of the wheelchair the Rear Folding Adapter can be moved further out from the wheelchair by using one or two Frame Clamp Spacers (UFCSPCR). Alternatively the Side Tube may lean slightly away from the wheelchair, or may incorporate an S-bend to avoid interference.
When the Frame Clamp Inner Piece is correctly aligned alternately tighten the bolts connecting the Cap and Body to clamp the wheelchair tube evenly.
Please Note
When the bolts are fully tight and the tube is firmly gripped there should be a slight gap of 1/32" to 1/64" between the Cap and Body of the Frame Clamp Inner Piece. If the gap is wider than 1/16" the Frame Clamp Inner Piece is probably too small. If there is no gap and the tube is not gripped firmly when the bolts are tight remove the inner
piece and tightly wrap some aluminium foil around the tube before replacing it. Make sure the aluminium foil does not get caught between the Cap and Body when the bolts are again tightened. There is some variation in the tube size on different wheelchairs so it is sometimes necessary to use the foil. Do not use paper or plastic. Do not use more than four layers of foil, more than this probably means the Frame Clamp is too large.
