Quickie Q7

Here you`ve got it, the piece it`s screw to the frame is aluminium and the rest it`s plastic composite.

thanks!
they are like tilite's composite scissors. except the frame mount.

Here is some additional information and pics of the orange one...

The specs...

18" front/16" rear STF Heights
80 Degree Classic Frame
No Front Frame Inset
COG = 2"
Caster Setting 2
Single Sided Forks
5"X1.5" Aluminum Soft Roll Casters
3 Degrees Camber
24x1 Spinergy LX Wheels with Natural Fit Handrims (No thumb grip)
Orange (No longer offered on the order form).








The new caster housing eliminates the infamous plastic plug/rubber O-ring caps used on the Ti, GT, GTi, and Q2-Lite that required the user to either gash their frame prying one out or having to organize a search party to go look for one after it fell out on its own.

The splines are still there, but only the screw on the underside of the housing needs to be loosened to adjust fore/aft angle of the fork. A cut-down 6mm Allen wrench is provided to access it without removing the caster. The small button head cap screw in the curved slot on the inside of the housing adjusts the lateral orientation of the fork. It can be used to correct left/right tracking problems due to fork misalignment. It requires a 3mm Allen wrench to adjust and can strip easily. This fastener is used way too much on this chair--most notably at the end of the caster axle on the two sided fork. For that reason alone, I spec'd the single sided fork on this chair which can be loosened with a 5/32nd Allen wrench. A 5/32nd is also used to adjust footrest length (Quickie seems to have difficulty deciding whether to go completely metric or SAE).



The ergo scissor lock design is slightly different. It uses lock nuts instead of retaining clips at the pivot points. The oval tubing of the Q7 also required the engineers to design a completely different clamp. Two pieces clamp to the frame tubing, and a third piece is used to actually mount the wheel lock to the clamp. A single socket head cap screw attaches the third component to the clamp and allows the wheel lock to be adjusted with a 4 mm Allen wrench (arrow) without having to worry about the clamp rotating or sliding on the frame. Slightly loosening it allows fore/aft adjustment. Loosening it until it almost comes out allow that third component to be positioned further outside or beneath the frame...


I'll post info on back angle adjustment some time soon.

The Q7's backrest hinge design is similar to that of the GT/GTi except that the Q7 has 4 adjustment holes instead of 3...




While the ability to adjust backrest angles on the fly can potentially be a useful feature, some of you may recall a previous post where I expressed some concerns that improperly trained end users may be at risk for flipping backwards due to the significant change in stability that can occur when changing back angles on a cantilevered frame wheelchair.

Sunrise has apparently heard similar concerns and taken them seriously because it is not possible to use that fourth hole until a plastic insert inside the bottom of each backrest tube is moved upward. The diagram from the parts manual shows the factory setting, the picture shows the setting after adjustment...



Depending on the amount of seat dump and back angle required, that fourth setting may be essential for some end users. I imagine many people who see the insert will assume it's simply a plug. Because of this, some who receive a Q7 may not feel comfortable with their back angle and not realize that the insert can be moved further up into the backrest frame to use that fourth hole...



Sometimes a little bit of knowledge can prevent significant dissatisfaction with a chair. Sometimes, a lack of knowledge can be potentially dangerous. That's why I post stuff like this.

Why is the caster arm angle on the green chair less than the orange chair?
The green chairs casters are much closer to the down tubes or to the front of the footplate. It has a much longer footprint which should add to stability.
What make is the green chair?
Thanks

I was hoping you would notice. It's an 18x18 85 degree Quickie Q7 demo we recently received which has the longer "classic" frame. 25 pounds with everything--including tippers, side guards and armrests.

I'm trying to find out if it was mistakenly built with caster housing "setting 1" instead of "setting 2" (see order form). It has a larger than necessary footprint for most everyday environments, is extremely stable, but is still easy to push. In fact, I spec'd one out for a veteran with a C5 injury last week after assessing him in it. He will still use his powerchair full time, but will use the Q7 indoors and as a backup

Did you see the pics earlier in this thread?

Brad, the Sunrise rep you recently praised on this forum, may be aware of the existence of this demo.

If it had different forks which could hold 6x1.5 soft rolls. Hmmm...

Those are excellent locks. At first I thought I hated them on my new GTX that I got in December because they were accessed under the seat but now that it's been 2 months almost exactly, they're wonderful! I don't leave them locked at night so they're not over-pressurizing the Schwalbe tires but they work really well!

I think this forks could hold 6 x 1.5", so if you order the chair with this one...

I was referring to the green Q7 forks which will only hold up to a 5" caster. The specs for the chair say "setting 2" when I looked up the serial number, but I am seriously doubting that. Since the Q7 is a new model, I'm suspecting that the demo was mistakenly fabricated with the caster housing at "setting 1" due to a glitch in the configurator they use to produce the chair.

If that turns out to be true, it would not be possible to order this configuration from Quickie without a custom build request (2" of frame inset or a caster larger than 4" require the more swept back caster "setting 2" to be selected).

Even if that were not the case, I'd be a little concerned about using the Q7's single sided fork (or any other manufacturer's single sided fork for that matter) at caster setting 1 with a 6x1.5" soft roll on an 18" deep classic frame. In that sort of application, the front casters are subject to a much greater load and would put a lot of stress on the caster axle compared to to most other configurations (see pic).

To use a 6x1.5" soft roll caster on the green demo, the tall wide fork from the GTi might work.

What would be the benefit of a slightly larger in diameter front wheel? Or would there be any? (I have 4"x1.5" soft roll frog legs now.)
