Definitions

  • the present invention relates to the mounting of communications systems for convenient use, and more particularly to a communications system with a mounting clip for attachment to a motorcycle helmet for use by a motorcycle rider or passenger.
  • motorcycle riders Due to the loud background noise produced by motorcycle engines, as well as the wind, it is very difficult for motorcycle riders to communicate with each other using their unaided voices. Many jurisdictions now require that motorcycle riders and passengers wear helmets. The thick padding of the helmets makes it even more difficult for a motorcycle rider to hear what others are saying. Typically, motorcycle riders communicate with their passengers by turning their head around to look back at their passengers and by yelling loudly. However, turning one's head to look back at a passenger can have lethal consequences because the rider's eyesight is no longer directed toward the oncoming road.
  • Two-way radios have been adopted for use with motorcycle helmets. These two-way radios have a speaker and a microphone mounted to the motorcycle helmet. These radios allow the motorcycle rider to communicate with others via radio communications. For example, the motorcycle rider can communicate with a passenger or with other motorcycle riders wearing similarly equipped helmets. The two-way radios allow the driver to communicate with the passenger without looking away from the road.
  • U.S. Patent 3,249,873 to Whittemore et al. teaches a radio secured to a helmet for military use. A strap is permanently secured to the helmet and supporting clips are attached to the back of the radio. The clips are snapped onto the strap to secure the radio to the helmet.
  • this design is not ideal for use with motorcycle helmets since motorcycle helmets typically do not include Whittemore's permanent strap.
  • U.S. Patent 3,273,163 to Andrews teaches an accessory attachment to a hard hat.
  • the accessory attachment has a hole for attaching various accessories.
  • the accessory attachment fits in a pocket formed in the thickened lower edge of the hard hat. This design is also not ideal for use with motorcycle helmets since motorcycle helmets typically do not have the pocket formed in a thickened lower edge as does a hard hat.
  • U.S. Patent 3,889,190 to Palmer shows a transceiver mounted to a helmet using a clamp mechanism.
  • the clamp mechanism uses a rivet to secure clamp members about the bottom edge of a helmet. This design is inconvenient because the rivet must be tightened or loosened to attach or remove the transceiver from the helmet.
  • U.S. Patent 3,983,602 to Barry teaches a one piece holder of molded plastic for attaching to the lower rim of a safety helmet.
  • the holder is not suitable for holding a communications system to a safety helmet, however, because it is designed only to hold long, slender objects.
  • the disclosure discusses using the holder to hold a pencil.
  • U.S. Patent 5,465,421 to McCormick et al. teaches attaching speakers to a helmet.
  • the speakers are either built into the helmet or are embedded in the
  • McCormick's design is used with a specially constructed helmet and thus lacks the versatility to be used with standard helmets.
  • McCormick's design is attached to a standard helmet by embedding posts into the helmet, thus damaging the helmet and preventing ease of transfer to another helmet.
  • U.S. Patent 5,590,209 to Pratt et al. teaches a mount for supporting a microphone and speaker on a helmet.
  • Pratt's mount is attached to the helmet using double-sided tape, which can make the transfer of the mount from one helmet to another slow and difficult.
  • the tape can leave undesirable residue on a helmet and can fail to provide a secure attachment.
  • Pratt alternatively provides for attaching the mount to the helmet using a screw passing through the mount and the helmet. This mounting method leaves a permanent hole in the helmet and makes it inconvenient to move the mount from one standard helmet to another standard helmets.
  • a detachable helmet-mounted communications system for use with standard, unmodified helmets. It would further be desirable for the mounting assembly to be quickly and easily detachable from one standard, unmodified helmet for quick and easy reattachment to another standard, unmodified helmet. It would also be desirable for the mounting assembly to be securely attached to the helmet, preventing unintentional disengagement.
  • an object of the present invention is to provide a detachable helmet-mounted communications system for use with standard, unmodified helmets. Another object is for the system to be quickly and easily detachable from one standard, unmodified helmet for quick and easy reattachment to another standard, unmodified helmet. Another object is for the system to be securely attached to the helmet, preventing unintentional removal from the helmet.
  • a mounting assembly includes a junction box for electrically connecting speakers and a microphone to a communications device.
  • the mounting assembly also includes an attached resilient clip adapted to use spring forces to elastically and removably grasp the lower peripheral rim of the helmet, thereby mounting the communications system to the helmet.
  • FIGURE 1 is a perspective view of the detachable helmet-mounted communications system of the present invention.
  • the mounting assembly is shown attached to a full-face motorcycle helmet (illustrated using phantom lines).
  • Speakers and a microphone are shown secured to the inside of the motorcycle helmet and are electrically connected to the mounting assembly via wires.

  • FIGURE 1 shows a detachable helmet-mounted communications system 110 of the present invention.
  • the communications system 110 includes a mounting assembly 112 with a clip portion 114, a housing 111 encloses a junction box 132, two speakers or earphones 116, 118, a noise-canceling microphone 120 and wires 122 for providing communication connections between the speakers, microphone and mounting assembly.

  • the clip portion 114 can grip around both the headshell 126 and the internal padding 128 or can fit between the headshell 126 and internal padding 128 to grip the headshell 126 as illustrated in FIGURE 6.
  • the speakers 116, 118 are mounted to the padding 128 in positions proximate to the ears of a person using the helmet 124. If the helmet 124 has built-in ear pockets, then the speakers 116, 118 can be mounted in the ear pockets.
  • the microphone 120 is similarly mounted to the padding 128 of the chin bar in a position proximate to the mouth of a person using the helmet 124.
  • the speakers and microphone can be mounted to the padding by using, for example, standard adhesive- backed Velcro pieces. Loop forming pieces of Velcro can be adhesively attached to the padding 128 at the positions where the speakers 116, 118 and microphone 120 are to be located.
  • Hook forming pieces of Velcro can then be adhesively attached to the speakers 116, 118 and microphone 120 so that the speakers and microphone can be removably attached to the helmet 124.
  • Some special helmets can have built in speaker pockets within the ear pockets for placement of the speakers 116, 118. If speaker pockets are built into the helmet then Velcro need not be used to secure the speakers 116, 118. Also, with some types of padding 128, the loop forming pieces of Velcro do not need to be attached because the hook forming pieces of Velcro can adhere directly to the padding 128 or to a lining material on the padding 128.
  • the speakers and microphone can be attached to the helmet 124 using any other conventional means as well.
  • FIGURE 2 shows the communications system 110 attached to an open-face motorcycle helmet 136 (illustrated using phantom lines). Because the open-face design has no chin guard for securing the microphone 120 a microphone and boom assembly 138 is used.
  • the microphone and boom assembly 138 can attach to the conduit 134.
  • the assembly 138 includes the microphone 120 mounted on the distal end of a flexible tubular element or boom 139. Leads are electrically connected to the microphone 120 and extend through the flexible boom for transmission of the electrical signals detected by the microphone 120 to the junction box 132.
  • the flexible boom 139 is adjusted so that the microphone 120 is positioned generally in a position proximate to the mouth of a person using the helmet 136.
  • the communications system 110 utilizes the clip portion 114 to attach the mounting assembly 132 to the lower rim 130 of the helmet 124 or 126.
  • the clip portion 114 is a single sheet of metal.
  • the clip portion 114 is stamped from a thin, flat, planar sheet of stainless steel.
  • the clip portion 114 is formed by folding over the stamped metal sheet of to form first 144 and second 146 opposing arms connected by a generally U-shaped joining portion or bend 148 (note FIGURE 6).

  • first 144 and second 146 arms are positioned relative to each other as shown in FIGURE 5.
  • the arms 144, 146 and the bend 148 exert an elastic spring force urging the first and second arms back towards each other.
  • the elastic spring force is used to grip the helmet between the first and second arms to mount the communications system to the helmet as illustrated in FIGURE 6.
  • the arms can sandwich the headshell 126 and internal padding 128 or can fit between the headshell 126 and internal padding 128 to sandwich only the headshell 126.
  • the clip portion 114 When attaching the communications system 110 to the motorcycle helmet 124 as shown in FIGURE 6, the clip portion 114 is placed at the bottom of the lower rim 130 and the second arm 146 is slid between the internal padding 128 and the headshell 126. As the clip portion is slid around the lower rim 130, the housing 111 is held out to spread the first 144 and second 146 arms apart. The clip portion is slid around the lower rim until the bend 148 is near the lower rim. Once in position, the housing 111 is released to allow the elastic spring forces to bring the arms together and grip the lower rim 130 and surrounding area of the headshell. As mentioned above, rather than sliding the second arm 146 between the internal padding and the headshell, the arms can be positioned to sandwich both the internal padding and the headshell.
