motv8tr Posted September 6, 2012 Report Share Posted September 6, 2012 Hi guys, this is for any of you who are mechanically creative. Basically I need an electrically operated retractable arm, the purpose is to attach it to the door from my garage to the back yard, ideally it would be plugged into a timer, the idea is to have it retract at a set time, opening the door to the yard for my dogs.....anyone know if such an item exists and where I might find it??? I was hoping princess auto? I was thinking maybe something along the lines of the ones used on awnings???? inexpensive ideas are welcome. Thanks Maureen Link to comment Share on other sites More sharing options...

motv8tr Posted September 6, 2012 Author Report Share Posted September 6, 2012 Does it come with a timer??? Link to comment Share on other sites More sharing options...
HTHM Posted September 6, 2012 Report Share Posted September 6, 2012 Yes the dog will go through it when the time is right... Here is an example of what I mean: http://www.canadapets.com/pet_doors.htm Link to comment Share on other sites More sharing options...
jedimaster Posted September 6, 2012 Report Share Posted September 6, 2012 I put in a doggy door and my beagle loved it. but the little bugger would steal stuff from the house and take it outside and bury it in the snow. Shoes, Stuffed animals, garbage, hair brushes, dishes, boxes, a paddle one time, he tried to take one of my boots but he got stuck. Link to comment Share on other sites More sharing options...
ttahhan Posted September 7, 2012 Report Share Posted September 7, 2012 If you are a little mechanically inclined you could go to the auto wreakers and pick up any Wiper motor and the transmission for it... The transmission is the linkage arm of the wiper.... Link to comment Share on other sites More sharing options...
motv8tr Posted September 7, 2012 Author Report Share Posted September 7, 2012 Guys, you're missing the point...I need to be able to have a door open on a timer so the dogs don't get out too early...I don't need a dog door, the back door is fine, besides, a dog door for my dog would run about 500.00 TS, that's a great idea, I go by a couple of wreckers on my way to work, I can check with them on my way home...just have to figure out how to hook it up to a timer...hmmmm I have a couple of ideas... Thanks Maureen Link to comment Share on other sites More sharing options...
ttahhan Posted September 7, 2012 Report Share Posted September 7, 2012 To Power up the wiper motor your going to need to supply it 12Volts. To do this you will need a 12V Power Supply you can buy one here Power Supply Install the timer and adjust the transmission arm to the door presto..... Let me know if you need any guidance happy to help... Link to comment Share on other sites More sharing options...
Bondar Posted September 7, 2012 Report Share Posted September 7, 2012 How about anyone of the ones at say a bank or grocery store ? If it's electronic it can be hooked up to a timer just like any indoor lamp timer no? Link to comment Share on other sites More sharing options...
motv8tr Posted September 7, 2012 Author Report Share Posted September 7, 2012 Wiser I looked at those, they are about 200.00 or more plus installation, I'm trying to stay cheap Thanks TS I appreciate your help Maureen Link to comment Share on other sites More sharing options...
DanD Posted September 7, 2012 Report Share Posted September 7, 2012 The wiper motor is a good idea; but not sure it would have the strength to open a door? A power window motor and regulator assembly definitely would have the torque. Something like the picture below; just loose the extra bracketing that’s not required for your purpose. Plus there are right and left hand regulators which are mirror images of each other; depending on which way your door opens. Just a thought. Dan.

jedimaster Posted September 7, 2012 Report Share Posted September 7, 2012 I doubt a wiper motor would open the door, also don't forget that you are going to need to turn the handle unless you are planning on removing it altogether or are you talking about a sliding door? The have automatic door openers, and I can tell you that the motors in those are a heck of alot more powerful than that in a wiper motor. If you are going for the wreckers I would recomend looking for a minivan with an autmatic door closer from a caravan or something like that over a wiper motor.

Fisherman Posted September 7, 2012 Report Share Posted September 7, 2012 Guys, you're missing the point...I need to be able to have a door open on a timer so the dogs don't get out too early...I don't need a dog door, the back door is fine, besides, a dog door for my dog would run about 500.00 Maureen Question: Is this a "one event" thing, door opens, dog(s) go out and stay out for the rest of the day and the door stays open to "other" intruders, or will the door shut after a preset time. One thing, dogs decide it's crummy out, don't go out and dump in the garage. Just a thought.. Link to comment Share on other sites More sharing options...
BillM Posted September 7, 2012 Report Share Posted September 7, 2012 A wiper motor would easily open a small door for a dog, no question about it... Turn your wipers on and see if you can stop them, lol! Link to comment Share on other sites More sharing options...
jedimaster Posted September 7, 2012 Report Share Posted September 7, 2012 (edited) The transmission would break. Ever tried to shut a door on a windy day? or open a door on a windy day? Bill the OP mentioned this is an existing entry door to a garage. I presume its a steel door and likely somewhat heavy. The motors in commercial automated doors are significantly heavier built than a wiper motor and transmission. They need to have significant power to shut a door against the wind. They also shut very slowly in comparison to what a windshield wiper works at for safety reason. I would say if they were making a new small door, I would go with a sliding setup and take the entire unit from a sliding minivan door. It even has safety mechanism built in to protect against cutting a dogs head off. As for a timer you could put it on a dual trigger, a timer and a pressure plate on the inside and outside so between say 7-9am the door is activated and if the dog steps near the door it opens. Might scare the crap out of it though... err prematurely that is. Edited September 7, 2012 by jedimaster Link to comment Share on other sites More sharing options...
motv8tr Posted September 7, 2012 Author Report Share Posted September 7, 2012 This would be a one time thing, the door would stay open until I get home, that would give the dogs access to in or out at will, I have been leaving the door open but now that I leave in the wee hours of the morning it seems my dogs are waking the neighbors....not good, so I would like the door to open a few hours after I leave, rather than leave them in while I am gone.

danbouck Posted September 7, 2012 Report Share Posted September 7, 2012 A wiper motor will handle the door no problem. Let me see if I can dig up any parts. I don't just make things go up and down, I have to make doors open too Link to comment Share on other sites More sharing options...
fisher Posted September 7, 2012 Report Share Posted September 7, 2012 I made a automatic door on a timer using 2 12 volt supplies, a timer, and an electric retractable car antenna. It is used on a chicken coop to slide open and closed an opening. Opens in the morning and closed in the evening (all on a timer). You can google this set up for chickens and get a visual/diagrams for what you need. But it may cost a few bucks unless you can get used equipment.
