Abstract

A construction helmet is disclosed having a housing detachably mounted thereon which supports a ratcheted take-up reel having a pair of ear plugs attached to a hub by flexible cords wound about the hub. The reel is rotatably carried on the housing and a manually operable plunger releases the reel for automatic withdrawal of the ear plugs into a storage receptacle on the housing. Strain relief elements are attached to each cord and the receptacle includes shoulder straps engageable with the strain relief elements. The plunger is releasably connected to ratchet teeth carried on the reel hub.

Claims

1. Reelable ear plug assembly comprising:

a housing;

a reel rotatably mounted internally in said housing;

a set of ear plugs;

cord means connecting said set of ear plugs to said reel;

a spring means operably disposed between said housing and said reel normally biasing said reel to withdraw said set of ear plugs towards said housing;

a manually operated plunger and latch means releasably coupled between said reel and said housing for selectively engaging and disengaging said reel from said housing;

said spring means includes a coil leaf spring having opposite end connected to said housing and said reel respectively;

2. The invention as defined in claim 1 wherein:

said cord means includes;

a single strand having two ends with one end fixed to said reel and the other end terminating with a closed loop;

a string passed through said loop having opposite ends secured to ear plugs respectively.

3. The invention as defined in claim 2 wherein:

said reel includes a hub separating a pair of side discs;

said teeth depending from one disc of said pair; and

each tooth having a flat surface slidably engageable with said housing disc.

4. The invention as defined in claim 3 including:

said string having a strain relief nub and stop adjacent to each of said ear plugs.

5. The invention as defined in claim 4 wherein:

said housing is provided with an opening passing said cord from said reel to said set of ear plugs.

6. The invention as defined in claim 5 wherein:

said plunger and latch means is yieldably and resiliently biased out of engagement with said reel teeth.
