as illustrated in fig1 - 4 , the present invention is a climbing oriented communication device , indicated generally at 10 , for use in improving communication methods between climbing partners . in the present invention , each element of the communication device 10 will be described first . fig1 illustrates the communication device 10 of the present invention having an outer casing 12 , gate 14 , climber interface system 30 ( comprised of earbud 31 and microphone 32 system combined with a retractor mechanism 33 ), plastic insert 21 to house internal components and store climber interface system 30 , operational dials 42 , and optional led 51 to indicate on / off status . not seen in fig1 are the internal components such as electronics and batteries , as well as the button used to control the retraction of the climber interface system 30 . also not shown are the internal speaker and microphone used when the communication device 10 is oriented as a hand - held walkie - talkie . fig2 illustrates the outer casing 12 and gate 14 , indicated generally at 20 , of the communication device 10 of the present invention used for maintaining the carabiner shape and provide functionality . the carabiner shape will be relatively familiar to the average climber and promote a secure , convenient , and trusted attachment . the specific dimensions of the outer casing 12 will be determined by housing requirements for the climber interface system 30 and internal components ( not shown ). the durability standards of the communication device 10 require that the unit must maintain functionality while enduring the common abuse associated with being placed on a harness or gearsling during a climb . this condition implies that ( i ) the outer casing 12 will most likely be constructed out of a lightweight , durable metal such as aluminum or titanium although constructing the outer casing 12 from other materials , such as plastic , is within the scope of the present invention and ( ii ) the case will include various seals and devices to be water , dust , and shock resistant . as illustrated in fig3 , the outer casing 12 of the communication device 10 surrounds an example of a plastic insert 21 . this plastic insert 21 provides insulation and protection between the outer casing 12 and the internal components . the plastic insert 21 houses the climber interface system 30 , electronic components , and batteries . as illustrated in fig4 , a climber interface system 30 is provided . the climber interface system 30 has an earbud 31 and microphone 32 system allowing for hands free , voice activated communication between climbing partners . preferably , the earbud 31 has a built - in , easy - grab , shark fin shaped appendage attached to or formed in the earbud 31 for quick and easy access . the climber interface system 30 combines with a spring loaded spool retractor mechanism 33 for quickly and conveniently storing the system while not in use . the operation of a communication device 10 of the present invention will now be described . a person skilled in the art will understand that the communication device 10 can be operated in numerous manners and that the description set forth below is merely one manner of operation . the communication device 10 of the present invention is powered on by using operational dials 42 . the power supply is indicated by the led 51 located on the top . using operational dials 42 , the user sets their volume level preference and designates a common channel of communication . while the climber interface system 30 is retracted into its protective recess , located on the plastic insert 21 , the communication device 10 has the ability to function as a hand - held walkie - talkie by utilizing a built in microphone and speaker system ( not shown ). the communication device 10 is attached to the lead climbers harness or gear sling and secured by the gate 14 . while the communication device of the present invention 10 proves useful for communication during the actual movement of climbing , the communication device 10 will probably be needed most when a climber transitions from the person who is climbing to become the person who is belaying . it is during this period that climbing partners are separated by as much distance as one rope length and will have to perform a variety of transition related tasks that often require the use of both hands . with verbal and visual communications severely limited , the ability to communicate clearly becomes extremely difficult . at this point , the lead climber employs the communication device 10 of the present invention by grabbing and pulling the earbud 31 of the climber interface system 30 from its protective recess . the earbud 31 is comfortably and securely placed in the climber &# 39 ; s ear of choice . once the earbud 31 and microphone 32 are pulled from their protective recess , the communication device 10 automatically changes from a hand - held walkie - talkie to a hands - free , voice activated communication device . a simple simultaneous push of operational dials 42 will serve as the “ call ” feature and notify one climbers need to talk to the other . when utilizing this climber interface system 30 , the user simply has to speak clearly into the microphone 32 and listen through the earbud 31 speaker . in this manner , a climber will be able to accurately and consistently know the condition and status of their partner , thus improving the overall safety of the climb . when the climber no longer needs to communicate with their partner , a button will be pushed to enable the retractor mechanism 33 and pull the climber interface system 30 back into its protective recess until future use is desired . operational dials 42 will be used to power off the communication device 10 . as illustrated in fig6 - 16 , in another embodiment of the present invention is the communication device 110 comprises a durable plastic and metal box 111 integrated with dual wiregate carabiner attachments 113 combined with a built - in , easy - grab , shark fin shaped retractable earbud 115 and microphone 117 . the communication device 110 of this embodiment provides secure attachment as well as continually maintaining the orientation of the communication device 110 relative to a harness or gearsling . by attaching each wiregate carabiner clip 113 to adjacent gear loops , the communication device 110 automatically and continuously faces in the desired , upright manner . the dual gates 113 of the communication device 110 of the present invention ensure that the communication device 110 has restricted horizontal and vertical motion along a harness or gearsling . the stable and consistent orientation provided by the communication device 110 is convenient and ultimately easier to use , both of which are important to the average climber . in one instance , the user can attach each wiregate carabiner 113 to adjacent gear loops , causing the communication device 110 to be positioned in the space between the two loops . this positioning helps to allow adequate room for other pieces of climbing equipment as well as ensure that the communication device 110 is as least intrusive as possible . when not in use , the earbud 115 and microphone 117 are adequately protected from abrasions and stresses by the outer casing 111 of the communication device 110 . having both operational dials 123 partially recessed on the top of the communication device 110 provides protection to the dials while allowing easy operational access . in addition , the communication device 110 has a rotatable antenna 121 and is powered on by using the operational dials 123 . using operational dials 123 , the user sets their volume level preference and designates a common channel of communication . the power supply is indicated by the led 125 located on the top . all the features of the previous embodiment are incorporated into the communication device 110 . in sum , the present invention is a climbing oriented communication device 10 , 110 designed to meet the unique communication needs of a rock climber . the communication requirements of a climber mandate a device that will provide hands - free , voice activated communication , a quick and secure method of attachment to a harness or gearsling , operational ability while attached to the harness or gearsling ( i . e ., the user does not have to remove it from the harness to use the device ), and ruggedness to endure a variety of environments and stresses . a climber communication device will also need to be simple to use and reliable . the features of the communication device 10 , 110 of the present invention satisfy these needs by including : ( i ) voice activated , hands free operation , ( ii ) operational ability while attached to a harness or gear sling , and ( iii ) durability designed to endure a variety of climbing environments . embodiments of the communication device 10 , 110 of the present invention include a device that is either carabiner in shape , incorporating a carabiner -
