Fitting the DAESSY Rear Folding Mount - DRFM6
Determining the Location for the Rear Folding Adapter
The Rear Folding Adapter (RFA) must be located partway down the side of the wheelchair between 2 and 5 inches below the seat level. The front-to-back location of the RFA depends on the In-use and Folded positions for the mounted device.
The In-use and Folded Positions
The In-use position will be determined by the needs of the user and the type of device being mounted. Devices that are operated with scanning or head-pointer function may be higher and farther away than devices that are operated by direct access.
The Folded position is behind the backrest of the chair where the device is in a protected and unobtrusive location that does not interfere with other items.
The folding motion results in the device being tilted through 90º from the In-use to the Folded position. This is an important consideration as it affects the clearance between the device and the backrest of the wheelchair, as well as any other fittings or items located on the back of the wheelchair. The Folded position of the device should be selected so that the device clears any obstructions.
Protecting the device in the Folded Position
A non-standard component, the Folding Quick Release Base (USBF), may be desirable in some situations, as it allows the device to be rotated on the Horizontal Tube. With the USBF it may be possible to configure the device in the Folded position so that the screen is facing inwards and the device is between the Horizontal Tube and the backrest. More details on the Folding Quick Release Base are found Quick Release Bases
Caution:
The screen of a laptop computer or similar device should be closed before folding the DRFM6 behind the wheelchair backrest.
Location of the Rear Folding Adapter
When the In-use and Folded positions for the device have been selected the required location for the Rear Folding Adapter (RFA) can be determined. The RFA should be no further than 2" to 3" inches from the halfway point between the In-use and Folded positions.
When the device is mounted for direct access with a folded position close behind the backrest of the wheelchair the Rear Folding Adapter will be close to the halfway along the side of the wheelchair. A device mounted high and forward for scanning or head-pointer access will require the RFA to be mounted ahead of the halfway point. If there is an obstruction at the back of the wheelchair the RFA may be moved behind the halfway point.
When the DAESSY Quick Release is used to attach the device to the horizontal tube the centerline of most devices is between 1" and 3" forward of the tube. For very precise horizontal positioning contact DAESSY for more information.
Steps in Fitting Procedure:
Fitting the DRFM6 has the following steps:
- Selecting a Frame Clamp location
- Specifying the Frame Clamp size
- Determining the Location for the Rear Folding Adapter
- Determining the Side Tube length and Offset Links required
