Abstract

A hardhat mount assembly (12) is provided for mounting a speaker device (14) on a hardhat (10), that allows adjustment of the speaker device position to allow the worker to choose a comfortable position. The mount assembly includes an inner mount part (50) for mounting on the hardhat, a linkage (100) having an upper end pivotally connected to the inner mount part and a lower end pivotally connected to the speaker device, both pivot connections having pivot axes extending in forward and rearward directions. One inner mount device includes a pair of wings (52, 54) with Velcro (74) on their inner surfaces that attach to Velcro pads (80, 82) that have been mounted with contact adhesive on a side of the hardhat. Another inner mount device includes a pair of plates (210, 212) with adjacent edges (214, 216) hinged together and distant ends (220, 222) that can be latched together to clamp a sweatband (202) of the hardhat lining between them. Another inner mount device (130) has a U-shaped part that straddles a thickened lip (132) at the side of a hardhat, and has at least one screw (150) that screws against the hardhat at a location adjacent to the stepped thickness of the hardhat lip.

Claims

1. A speaker hardhat mount assembly for mounting a speaker device on a hardhat that has front and rear hardhat ends and opposite hardhat sides, comprising:

an inner mount part for mounting on one of said sides of the hardhat, said inner mount part having a mount pivot connection part;

said speaker device having a frame with a frame pivot connection part;

a linkage that connects said pivot connection parts;

said linkage having at least a first rigid link and having opposite linkage ends each pivotally connected for pivoting about pivot axes to the mount pivot connection part and to the frame pivot connection part;

said pivot axes each extends primarily in forward and rearward directions, whereby to enable fine adjustment of the height, angle and orientation of the speaker device with respect to the ear of a wearer of said hardhat.

2. The assembly described in claim 1 wherein:

said linkage includes a plurality of links that are all of about the same length, said links being connected end-to-end for pivotal adjustment thereat about an axis that extends in forward and rearward directions.

3. The assembly described in claim 2 wherein:

said links each includes a screw at each end of the link and lying on the corresponding axis thereat, each screw being loosenable for link pivoting and tightenable to fix the relative pivotal orientation of a corresponding pair of links.

4. The assembly described in claim 1 wherein:

said linkage includes a single rigid link forming said opposite linkage ends, said single link having pivot axes at said opposite ends, said pivot axes being spaced by between 0.5 inch and 2 inches.

5. The assembly described in claim 1 wherein:

said inner mount part includes a pair of rigid plates with upper and lower horizontally-extending edges, a hinge that pivotally connects a first of said pairs of horizontal edges and a latch that locks a second of said pairs of horizontal edge together when they are pivoted together, whereby to enable rapid mounting about a liner band of the hardhat.

6. The assembly described in claim 1 wherein:

said inner mount device includes a rotation joint that connects said mount part to said pivot connection part thereof, said rotation joint allowing pivoting of said pivot connection part about a rotation axis that is perpendicular to said pivot axes.

7. A speaker hardhat mount assembly for mounting a speaker device on a hardhat that has a hard shell with an outside surface and with front and rear shell ends and opposite shell sides, including:

an inner mount part having a pair of elongated wings for lying against a side of the outside surface of the shell, said wings having proximal ends that merge and distal ends that are spaced apart, said distal ends lying above said merged proximal ends, and said inner mount device having a lug extending from substantially said merged proximal ends;

said speaker device being held on an end of a linkage that is pivotally coupled to said lug.

8. The assembly described in claim 7 wherein:

said inner mount part includes a downward tab part that extends downward from said merged proximal ends.

9. The assembly described in claim 7 wherein:

said wings have inner surfaces that are concavely curved, whereby to conform to the hardhat.

10. The assembly described in claim 7 including said hardhat, and wherein:

said wings have inner surface for facing the hardhat and have Velcro on the inner surfaces; and

including

a pair of Velcro pads adhesively attached to one of said hardhat sides at locations to attach to said Velcro on said wings.

11. A speaker hardhat mount assembly for mounting a speaker device on a hardhat that has front and rear hardhat ends and opposite hardhat sides, comprising:

an inner mount part for mounting on one of said sides of the hardhat, said inner mount part having a pivot connection part;

said speaker device having a frame with a pivot connection part;

a linkage that connects said pivot connection parts;

said linkage having at least a first link and having opposite linkage ends each pivotally connected about a pivot axes to the pivot connection part of said inner mount part and to the pivot connection part of said frame;

said pivot axes each extends primarily in forward and rearward directions, whereby to enable fine adjustment of the height, angle and orientation of the speaker device with respect to the ear of a wearer of said hardhat;

said inner mount part includes a pair of wings for lying against a side of the outside of the hardhat, said wings having proximal ends that merge and distal ends that are spaced apart, with one distal end lying forward and above said merged proximal ends and the other distal end lying rearward and above said merged proximal ends.

12. The assembly described in claim 11 wherein:

said inner mount part includes a tab that extends downwardly from the merged proximal ends of said wings.
