It's going to be a while yet due too development and time but will post pics as and when something happens I can resist everything except TEMPTATION

Only required when using off-road tyres. No need for weight/ugliness of empty carrier at other times. Might also be a "dangerous projection" with no wheel fitted.

Yes - but it could be hinged to come down from the vertical to that position, and go back up to lock for travelling. Not always possible to park with space to swing carrier far enough to open tailgate.

Locking? Why not just use a padlock if you're that paranoid?
Because of having to unpadlock every time tailgate is opened. Wheel would be padlocked to carrier, of course. Maybe you have not yet met the bad boys who run between vehicles stopped at lights and open tailgates so their mate 4 steps behind can nick what falls out?A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill. It does reduce the likelyhood of you dying when really, really ill. Stay Alive - KEEP AWAY FROM PEOPLE.

What I'm developing will be easily removable and won't leave a pivot post
Are you thinking of only dropping the wheel or the whole carrier for access? It would be a very complicated and expensive linkage
As for someone opening the tailgate surely a carrier equipped car is more difficult to enter I can resist everything except TEMPTATION

So why not put your road tyre on to prevent the 'dangerous projection'? Or do you like emptying the boot, putting the rear seats up, winding the winch down, scrabbling around for the spare and doing it in reverse when you have to change a flat?

So the carrier hinges out and down to get to the top section - do you then reach over it?

I live in inner city Liverpool so we have a fair few 'bad boys' - if you've enabled central locking what it does it matter if they open the carrier - the boot is still locked? If you've not got it enabled I'd be more concerned about the 'bad boys' climbing in the front with me......I see no ships........

Have wheel (and a bit of the mount) hinge down enough to let top go up past it.

It's not entering the car I'm thinking of. If the carrier isnt locked these bad boys could release it. The driver then would have to get out to close it - maybe not the best thing to have to do in that sort of situation, or drive off with it swinging about.

What I'm designing will latch automatically either in the open or closed so that would prevent that problem
As for dropping the wheel down the linkage required would be very complicated due to needing some sort of assistance either a spring or gas strut to help lift a heavy wheel back up and I think it would need to drop approx 18" to allow the tailgate to open I can resist everything except TEMPTATION

Sonic - if you can make a wheel carrier that has all this (central locking, multi-hinge, easy remove) at a price that undercuts the boys at Rasta etc then you'll be on a winner......
Just to point out though - the Rasta carrier has what seems to me a strong damper. If it was opened and I drove off because of the bad boys I think it would hold to get me out of there.
As for swinging about I would be surprised if it ever hit the car.....
If need be the Rasta (and Big Country) carriers can be removed - all it leaves is a hole in the bumper skin that can be covered with a plate.I see no ships........

Im pretty sure the Rasta does not have a damper correct me if I'm wrong. I think the idea of linkage to drop the wheel is a non starter, it could easily double the price due to the linkage required.
If you remove a Rasta or Big Country you will also have the latch receiver as well as the pivot I can resist everything except TEMPTATION

Hi Sonic - the Rasta I have plus the Big Country in my garage both have a strut similar to, say, the bonnet struts.
When you open the latch the damper allows a controlled swing open plus limits the range it opens.
My Rasta opens at roughly a right angle to the car.
I know from the Big Country if the damper swings too quickly a simple tighten of the bolt stiffens it nicely.
Agree about the latch receiver - that is there and would be a pain to remove and it's not pretty.
The idea of an integrated unit is cool so it can be taken off - the hole could easily be plugged with a suitable 'grommet' type effort.
Having handled both Rasta & Big Country I do know these things weigh a fair old bit - if you could reduce that significantly without compromise on strength that would aid removal.
Having said that I still like to keep mine on even when I run road tyres - these carriers have their pros and cons and aren't everyone's cup of tea.
But go for it - it's only by this sort of discussion that things move forward and improve I see no ships........

Just trying to improve the wheel the cost of these and other carriers in the uk are stupid. I already manufacture a swing away carrier for Defenders so now I have a D3 it's the next obvious project for me I can resist everything except TEMPTATION

I'd buy one.......Having a cargo barrier and dog cage, its near on impossible to extract the spare without taking apart the boot area......been there and done that, and was considering a swing away just for that reason....Will keep an eye out on your project Sonic

Sonic3d, you can fabricate the swing arm to have the pivot shaft with
a spring loaded lock pin, and the pivot bush part inside the bumper
as I had done. I intergrated the locking latch with the tow bar drop
plate. Also had a slot machined into the bush boss for a locating pin
in the pivot shaft, when in the full open position the whole swing arm
assembly can be pulled out, but when closed will prevent it from
jumping out. In a nut shell, remove wheel, pull out carrier and
remove tow bar.
D3 bullbar-spots-roof rack with spots-ladder-long range tank-swing out spare wheel carrier- upgraded tow bar-dash console-internal water tank-duel awnings-drawer system & T T.
How does your design behave off-road? It looks like it may flex/bounce around a little.
The above is a query/observation not a criticism.

I will buy 2 if you can price them more affordable than the mentioned brands, did you consider an version to carry 2 tyres like Kaymar? A few mods... and keeping it all running...Faultmate MSV2
