Hinges for hatch in the terrace

[Spik12]

Hi, I would appreciate some tips regarding the choice of hinges for a hatch I plan to build into the deck. The hatch will be fairly heavy since I will be using decking boards and it will be about 1.6m x 0.8m. As mentioned, grateful for any tips.

Is it something you will open frequently?

 

[Spik12]

Hello Anders, no not frequently, a few times a year. You can see it as an inspection hatch.

I have one of similar size, lying loose on the joists with 28*120. Stable and nothing moves. Lift with a crowbar, can make it fancier with an angled metal and handle that just fits down into the gap.
Do you really need hinges for the few times?

Here's how I did it:

Yours will be larger and heavier, so maybe gas springs can help.

Anders S you are absolutely right, probably don't need any hinges, most likely a drilled hole for a finger is enough to lift it when needed, thanks for the input 🙏.

Boat accessory dealers have all types of stainless hinges, plus deck fittings that are recessed handles for opening.
Erlandssons brygga
Nautec
Watski
Hjertmans
etc.

Hi, thank you for your responses, appreciated 🙏 a question for the one of you who mentioned chamfering an edge so that the hatch can be opened (or opened more easily at least), which edge? On the hatch or the wooden deck or both?

 

[Stefan N]

Have no hinges or beveled edge, just loose and they lie nicely.

If anything needs to be chamfered, it's likely in the hatch, on the underside of the side of the hatch that is lifted.

Kind of like this, drawn with finger paint on the bus...



But you'll probably notice, and it depends a bit on how thick the hatch is, how long it is, and what gap you already have...

This is how I made it, a stable and relatively easy hatch.

Stylish, and a bit beveled on both ends of the hatch.

Nice, and a little beveled on both ends of the hatch.

Yes exactly, I also beveled the transverse bars on the hatch so it guides correctly without hitting anything. I use it daily so I wanted it to be as lightweight as possible.
