Hi Peter,

Wow, thats a great idea! Most of us work alone so stuff like this is a boon.

Where are you on the manufacturing process? Any chance of seeing them in the merchants soon?

 I especially like this as essentially it costs the same to make (virtually) as a regular hinge (once the numbers start to mount up) the benefit is in the genius design and the increased ease of use. Brilliant!

hi Ian, thanks for your comments,the idea came to me when 3 of us where hanging a fire door in a pub refurb about 3 or 4 ft off the ground,was very heavy, came to me in bed late at night, i wasted 4 years waiting for a utility patent i was advised wrong as a design patent was ok, been trying to get people interested but too many want $1000s or pounds where i am,  sent it to QVC. USA who then passed it on to Crown bolt hardware in  CA who have shown interest after looking at the video so keeping my fingers crossed, anyway very pleased you like the idea, can i ask  are you in  construction? i would hope it would take over from the old hinge as you can still use it the conventional way, i have hung the door 6 inches off the ground on my own but had to take the top hinge off then hung it off the middle hinge, i let my wife hang a lightweight door on the bathroom frame. kind regards Peter

Yes Peter, 

Was builder in UK for 25 years, bricklayer by trade but I used to do the whole deal so carpentry made up half my work. Now I am working in Norway half on the tools and half helping others on their projects via online blog etc.

I always struggled with doors as my work in the UK was high end and doors are thick and heavy! Trying to lift a door into position, pick up the drill driver, hold the door, position the hinge, hold the screw etc AND get the first damn screw tightened without anything slipping is a nightmare.

If you want my advice, I'd make sure the design is bullet proof using an industrial designer, get a bunch made and give them away to people in the trade media. I read a lot about startups and the consistent theme seems to be getting it out there and then the rest takes care of itself. Once people see how good the idea is any half decent hardware company is going to want to be on board. Licencing seems to be the way to go (unless you want to go it alone and sell them yourself) Stephen Key has a great book on the subject.

I got my patent for my tool a few weeks ago and am too busy developing other things so I am looking at licencing the tool to a company after following Mr Keys book.

Feel free to keep me in the loop, it's a startlingly simple idea, and the best ones always are!

Best regards

That is a good idea, but with fire rated fire doors, I always just took the pin out of the top before hanging them. I lined the hinges together and placed the pin in, then just swung the bottom hinge in place and screwed them, then the center hinge.. Never had a problem that way. With your hinge, the first is holding all the weight and even with a hollow metal frame, that's allot for 1 screw to hold while you let it go to set the bottom. If its a solid core wood door, you better have that 1 screw long enough to go through the jamb and in to the stud, or it may pop out and drop.


Over all its a great idea

Hi John, thanks for your imput, i know i have tried it a few timeson fire doors at work and its ok as long as you have put the screw in far enough as you would with an ordinary door hinge, for the 2 and a 1/4 inch doors with any hinge you would make sure any hinge would hold, so i would put a bigger frame and longer screws in  and even if it dropped a bit you can get a bar under it to jack it u pa bit to slide it over the bottom hinge, we have used the lift off hinges with fixed pin and we had to remove the top and middle hinge as when you lifted it up it hit the architrave, i hung a standard door above 6 inches off the floor but had to take the top hinge off and was easy to drop the middle hinge over the screw and then the bottom screw all i had to do then was slot the top hinge back in[position, i have videos of using the hinge on top hung window and side hung window openers again it was easy and would save being on a ladder or a scaffold tower or even a cherry picker 2 or 3 stories up, i am glad you mentioned about the heavy doors but as with everything you have to scale everything up to suit or down for that matter which i will do for window hinges, take care Peter

thanks again Ian,i think theres not much more you coul;d do with an hinge improvment although i could be proved wrong you never know do you, you are right getting it out there is the hardest bit after inventing it with all those scammers out there, when you see videos of people hanging doors they always cut to the chase and never show the hard bit of getting it on the frame, us tradesmen are used to it but as you get older it becomes harder and thats what made me think of this idea, ive seen lots of ideas and they dont work well but they have managed to get them on the shelves, i have almost finished another idea which is a follow on from hanging a door, cant say much at the moment till i post it to uk patent office, lots of people struggle with doors carpenters as well, ive not done too bad in the 45 years ive been in the trade but have dropped some boo boos but its how you get over it that counts as we all make mistakes, can you tell me about your invention or is it it under wraps yet ? anyway best of luck with it we all need loads of it would never have thought it would be this hard to get this thing going, regards Peter

It sure is a complex process for a lay person to get something to market, especially with limited resources. My invention was a little gadget that measures the crossing angles of builders lines. Useful when setting out a building, esp. unusual angles etc. 

I've just been reading a post by Stephen Key over on a blog called Entrepreneur, here is the link, Your hinge came to mind!

Contact hinge manufactures like Hagar, Stanley, and any other brands. I could have it licensed for you in no time if they like it and see the benefits. Just get to looking for the hinge manufactures and brand names and start calling them to see if they have interest, if they dont, no loss, if they do show them your video and if they are still interested, send a prototype. Next thing you know you are in negotiations for a deal. Not very hard.


If you need help, we can help at no fee, just 15% of your royalties for the life of the product. We are a U.S corporation in Florida. and ask for no money upfront, we win if you win and that's it. My partner is selling her screws world wide and we have all the professionals needed to negotiate a deal successfully and a patent attorney.

Hello John,

 Thanks again for your interest.
 Licensing would be the best way for me to go at this time and would  appreciate your help in this matter.  At the moment,  i just don't have the time to go out and go round all the companies, also i have never done this sort of thing before and wouldn't know how to approach them. plus i need to go to work. 
I can send you more videos of it in action and more info, i have sent some emails out and asked for an NDA but never seem to get a response, so no one gets to see the video and that is why i posted it on buildersinvention site. 
I have UK and USA design patent,looks like you are in the right area to be able to push it forward with your partner selling screws. 
Could you tell me what are the royalty rates i dont have a clue on this.   
 kind regards and look forward to hearing from you,

Licencing rates are usually in the 4 to 7% range dep. on estimated volume expected. 

Usually you would put together a one page 'sell sheet' and telephone companies asking if you can send it. I called Spear and Jackson in the UK and and they said 'sure send it in and we'll have a look'. That was 3 or 4 emails ago and we are going back and forth at the moment. I'd not make much money with licencing at 5% but for me that's not the total point. I like the idea of the tool being available since that completes the project for me. A patents not worth the paper its written on otherwise as they say!

It might be worth looking what type of hinges are common in the USA because if it 'fits' that market it's a much bigger pie. The hinges here in Norway for example are totally different. All doors here are factory fitted into a common frame, doors just click into place, takes seconds. Everything is prefinished too.

Coo, going on now!

Cheers for now
