I’m building a toybox from red oak for my son, and I would like to make the lid so it opens automatically when you flip a latch. The lid I don’t have build yet but the approximate weight should be about 35lbs. I would like the lid to stay open at least 90 degrees, but I wouldn’t be opposed to having it open a little more. Anyone have any recommendations on what type of gas piston I should use? Would these work well?

You don’t say how old your son is, but it seems to be that your design might pose a safety risk (smashed fingers) when closing the lid, if it closes like a gas piston actuated car hood or read hatch- they (almost) open themselves, but move pretty fast just before latching when closing.

If pinched fingers are a concern, you might want to consider a soft closing lid support rather than self opening. When I built toy boxes for my 3 year old grandson, I had very good luck with these: They don’t lift on their own, but are easy to lift, and hold the lid open vertically. More importantly, with a slight nudge, the lid will close slowly on its own, and resist quick closing (slamming). No accidents in 2+ years.

My son is 14 months, that was my concern was smashed fingers, head ect. But I was planning to have resistance on the lid at all times so you would have to push it closed and engage a latch. Then when you flip the latch the box opens slowly.

I’m opposed to any sort of latch on a child’s toy box. I was a Deputy Medical examiner for 19 years while in law enforcement. In that training a case was presented of a child suffocating in a toy chest due to a latch. That case has given me reason to err on the side of safety when I build my grandson’s pirate’s chest for his 3rd birthday next fall. I’ll look long and hard before buying hinges, no latch of any sort.

Have your say...
