ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a safety helmet structure with a hand-free receiver.
2. Description of the Related Art
A conventional safety helmet structure with a hand-free receiver in accordance with the prior art shown in
FIG. 5
comprises a safety helmet
40
, and a receiving/speaking device
41
mounted on the outer wall of the safety helmet
40
. The receiving/speaking device
41
is connected to a mobile telephone and includes an earphone
42
, and a microphone
43
.
However, the conventional safety helmet structure with a hand-free receiver has the following disadvantages.
1. The receiving/speaking device
41
is mounted on the outer wall of the safety helmet
40
, so that it is easily broken due to collision.
2. The earphone
42
is extended to the inner wall of the safety helmet
40
and located at a constant position thereof. For different users, the position of the user's one ear relative to the inner wall of the safety helmet
40
is different, so that the earphone
42
is not available for different users.
3. The position of the earphone
42
is fixed, and the earphone
42
cannot be closely rested on the user's one ear, so that the hearing effect is not clear.
SUMMARY OF THE INVENTION
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional safety helmet structure with a hand-free receiver.
The primary objective of the present invention is to provide a safety helmet structure with a hand-free receiver, wherein the seat may be hidden in the safety helmet to prevent damage.
Another objective of the present invention is to provide a safety helmet structure with a hand-free receiver, wherein the position of the seat may be adjusted to suit requirements of different users.
A further objective of the present invention is to provide a safety helmet structure with a hand-free receiver, wherein the seat may be closely rested on the user's one ear, thereby enhancing the clearance of the sound.
In accordance with the present invention, there is provided a safety helmet structure with a hand-free receiver, comprising: a safety helmet formed with a base portion which is located at a position adjacent to a user's one ear, the base portion provided with an elongated insertion groove which is provided with a threaded seat that has a thread, a seat mounted on the base portion and provided with an insertion flange that may be inserted into the insertion groove of the base portion, the seat having a receiver, and a speaker, a signal connecting cord extended from the seat, and connected to a mobile telephone, the seat provided with a through hole for passage of a threaded rod, the threaded rod provided with a thread that mates with the thread of the threaded seat, and a spring mounted between the base portion and the seat for adjusting the protruding position of the seat.
