Motorising A 5 Point Locking Door - Idea's Please

[arfur mo]

i went out to a new client on Friday, he is severely disabled and completely wheelchair bound.

he uses a 'Pollock wheelchair system, basically IR receivers on the room walls and a transmitter built into an arm rest on his chair, it allows various remote actions like heating, lighting and so on. The company will supply the interface and already being sorted

currently he has a wooded font door which is very drafty, so he wants to replace it with a solid plastic door unit, he pal is a DG maker and knows me, so its how i've got involved

i can power the open/closing of the door with no issues as i have installed quite a few motors, but what i need is a way to motorise the the security lock and 5 point locking system.

if i simply add a night latch, he feels very vulnerable s the security is not really high enough for his personal concerns, maglocks even mini-mags on the inside are not an option due to the inner reveal of 9" and a narrow passage, so no room for a monster Z&L bracket, even if he were to accept the ugliness, and obviously maglocks would be useless if fitted on the outside for a home security needs.

i'm not over keen on a sheer magnet option, or a solonoid bolt in the top, the worry of side pressure if he happened to tip out and end up against the door, i've found in the past the pressure on a door secured this way, usually loosens the joins overtime from when somebody pushes to hard or to often while held by the locking device.

ideally, i need a way of rotating the lock shaft as though turning the internal handle, and i have wondered about using a car window electric winder adapted to it.

he is happy and able to pay for what he needs and he gets disability assistance in the costs, his condition and disabilities you will know what i mean when i say (well if you have a heart) you just want to offer the guy your best possible ideas and resolutions toease his world, and at sensible prices.

my side of it will be to work at bare minimum as possible costs, as i just feel where i can i'll help the less fortunate people, but it must be effective and workable at the same time.

You can get motorised multi point latches.

A more suitable and cheaper option is to simply replace lock with split handle and night latch feature (no doubt a locky will be along to give correct name).

Cost drops from £250 upwards down to around £75

Thanks Andrew,

appreciate you thoughts, his problem is he can't turn any handles, his movement is that severely restricted. i think at the back of his mind is that one day mum and dad simply won't be around to care for him, and he might loose what independence he has.

put simply, he could not overcome the night latch spring, or even get near to reach it, light switches and other every day controls are all about 2 ft from the floor just in case the remote packs up on his chair.

i could easily fit an electric keep to over come the normal night latch and the dead locking tongue, but then he can't securely lock and then unlock the doors 5 point system as we easily would.

to give you some idea, his mum folds his legs just so he can hold a drink and use a straw. his range movement is just so limited, to using the joystick controller on his chair and texting on an iPhone.

so its a real toughy, and i'm either a real softy or that Christian bit we all are supposed to have somewhere in our souls, is tugging really hard at me at the moment to help him, so i'm just hoping the access based guys in here could offer me some ideas or know of any kit for this use.

if not, as i write this i'm wondering if there are any rotary actuators in the world of machine robotics field that might be adapted/altered to this use?

You can get motorised mlti point locks though. Just the price is somewhat eye watering.

Whilst i wouldn't buy from there, have a look at locksonline.

will do, might have a look at dorma see f they have anything

thanks again Andrew

You need to speak to door peeps Arf. They will have their preferred mechanical lock. If door not made yet then tell them to hold off until you have one. Many different styles - obviously. They may even already know of one from their current supplier.

Have a look at GU

Way back in the 70s there were a lot of electric window winder add on accesssories about. sort of a motor/gearbox/clutch in a housing with a fitting for the shaft, that you just fitted in place of the handle. I think there was even one for a square shaft

If you want to go with a DIY sort of set up, that might be worth looking at if you can find one, prhaps at a scrap yard or a classic car parts place. But arent you worried that the bloke could get locked in if it goes wrong ?

Spal make automotive window kits, we used to fit them back in the day.

I'll have a look for a link.

like a handle on the inside?

arf we do a bit of access for the less able at home etc. best thing we have found is to replace the existing locks with a combination of mag, solonoid bolt and rim release. yes all 3 lol.

having said that we have never done it to a plastic door and if the front is plastic we hope the back is wood / ali. plastic doors usually have a lip / step at the base that makes them less practicle for less able access anyway. plus the locking of them usually requires a stiff push up on the handle

Dont suppose the frames wide enough for two flush mags mounted vertically is it ?

Like sometimes fitted to the entrnce to blocks of flats on dodgy areas. Have to be careful though, I got collared by a resident of one we'd done that way once. He was moving house and they couldnt get the washing machine out through the reduced gap..lol
