Can one AED defibrillator hard protective case serve all three sites?

A: Not by default. The wall needs 4×φ6 mm holes, the cabin has to pass a 1.2 m six-face drop, and the column needs 120 mm of clearance.

How is the 45 N pull measured?

A: Pull the handle straight up with a force gauge and read the peak as the lid leaves the gasket: a 4.6 kg sample with a 105° stop lands between 40 N and 48 N.

Are four φ6 mm holes enough on a 4.6 kg AED defibrillator hard protective case?

A: One M6 anchor in C25 concrete holds about 3 kN in tension, so four give 12 kN, roughly 260 times the case weight. The limit is edge distance; under 22 mm the shell cracks first.

Is IP67 at 1 m for 30 min enough in a cabin?

A: Yes. Cabin water is spray and rain under 5 kPa, well below the 10 kPa of a 1 m column. The harder case is the step between 60 ℃ and −20 ℃.

Where does 120 mm of clearance come from?

A: The case is 180 mm high, and at 105° the lid edge sweeps 180×sin15°, about 47 mm, behind the hinge; add 73 mm for knuckles.

AED defibrillator hard protective case

Quick answer: An AED defibrillator hard protective case runs 480×360×180 mm outside, 430×310×140 mm inside, 4.6 kg empty, with 4×φ6 mm wall holes and a 105° lid.

FAQ

1. AED defibrillator hard protective case at three deployment points

A corridor wall unit never moves. The load is 4.6 kg plus a few dozen lid cycles a day, and what ages is the shell around the fixing holes.

An ambulance cabin is a different problem. A speed hump loads the case at 3 g, so 4.6 kg briefly pushes down with 135 N, and the lid is the first part that wants to leave. Two latches answer that: 320 N each, 640 N together, against a lid and 30 mm pad near 2.1 kg.

A terminal column adds geometry. Columns run near 400 mm, and a clamp band pulls the case onto them, so it projects its full 180 mm height; at 105° the lid edge swings 180×sin15°, about 47 mm, behind the hinge.

Deployment point	Single-point load	Case design response
Corridor wall	about 3 kN per fixing	4×φ6 mm holes, 22 mm edge distance
Ambulance cabin	1.2 m drop, six faces	2 latches, 320 N holding each
Terminal column	47 mm lid sweep	105° lid angle, 120 mm clearance

2. A 105 degree lid angle and a 45 N one-hand pull

45 N is the ceiling for a one-hand lift, set from what an adult can pull up without bracing. Past it the AED defibrillator hard protective case takes two hands, and two hands means putting something down first. The lid weighs 1.9 kg, so 180 mm from hinge to edge already costs 3.4 N·m; 45 N over that arm gives 8.1 N·m, and the rest compresses the gasket.

The 105° stop lets the lid pass vertical by 15° and stay there. Below 100° the centre of mass is forward of the hinge, the lid falls back and pinches a hand; above 110° the rear hinge goes from tension to prying. On an AED defibrillator hard protective case, 105° is the band between those two failures.

5 000 cycles is the floor for hinge and latch life: two years at eight openings a day on a wall, eight months at twenty in a cabin. With the gasket at 25%, the pull climbs from 45 N to 53 N.

3. Reworking the fixing holes from wall to column clamp

Wall fixing has four layouts, and the wrong one means drilling again. The four-corner 4×φ6 mm pattern with M6 anchors and a 22 mm edge distance is the default, and slotting each hole to 6×10 mm absorbs ±2 mm of wall flatness.

A clamp band moves the holes to two horizontal slots on the back, 120 mm apart, on a 30 mm band. That forces the clearance to be recalculated: the band holds the AED defibrillator hard protective case 40 mm off the column face, and 40 mm of the 47 mm lid sweep is already gone.

Cast-in inserts belong to new walls only. The pattern has to be drawn, 60 mm deep, within 2 mm of plumb, because an AED defibrillator hard protective case has no adjustment left once it is up.

Fixing pattern	Hole type and count	Base it suits
Four-corner wall	4×φ6 mm round	Masonry, double-layer plasterboard
Back slots	2 sets of 6×10 mm	Column clamps, cabinet sides
Base counterbore	4×φ8 mm countersunk	Vehicle floor, cast-in plate

4. Gasket compression, breather valve and the IP67 line

IP67 at 1 m for 30 min is a whole-case rating built on three variables: gasket compression, latch holding force and breather opening pressure. The contact band is widest at 25%; under 20% the seal breaks at the corners first.

The breather opens at 18 kPa. A 430×310×140 mm cavity holds 18.7 L, and a 20 ℃ corridor against a 60 ℃ cabin makes only about 8 kPa, so the valve stays shut and the latches carry it.

The −20 ℃ to 60 ℃ range is written for the rubber: at −20 ℃ the gasket stiffens and 25% compression needs over 60 N, which nobody opens one-handed in gloves.

Lid clearance needed	Value	What happens when short
Wall mounted	≥80 mm	Lid scrapes the wall, paint wears through
Column clamp	≥120 mm	Lid hits the column, 105° never reached
Vehicle side wall	≥150 mm	Lid rebounds into the wall on bumps

5. Wall thickness, foam and temperature headroom

The 430×310×140 mm cavity takes a 30 mm PU pad, 30 mm per side, leaving 370×250×80 mm clear of the wall.

3.0 mm is the floor for this class. The 480×360×180 mm outside works out to about 0.65 m² of surface, and a 3.0 mm wall shortens the flow path 18% against 2.5 mm, lifting weld-line strength a grade; a 4 mm cross rib at 70 mm pitch adds roughly 30% bending stiffness.

Empty at 4.6 kg, this AED defibrillator hard protective case sits at the edge of one-hand carrying. Past 5 kg the handle widens from 22 mm to 28 mm, and loaded to 12 kg it wants a trolley.

Conclusion

The three sites look like a change of address, yet on the drawing they become three numbers: 4×φ6 mm holes, a latch force that takes a 1.2 m six-face drop, and 120 mm of clearance. Once the outside and cavity are fixed, 45 N and 105° lock the feel of the lid on any AED defibrillator hard protective case. Set the location, then the holes, then check clearance; reverse that order and the shell goes back to the mould.
