For a better understanding of the invention reference is made to the following detailed description of the preferred embodiments of the invention which should be taken in conjunction with the above described drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
Various aspects of the present invention will evolve from the following detailed description of the preferred embodiments thereof which should be referenced to the prior described drawings.
An embodiment of the invention as a whole is depicted in the drawings by reference character 10. The device 10 includes as one of its elements a housing 12. Housing 12 is formed with a top 14 and a bottom 16. Ridge 18 may also be included on the outer portion of top 14 for the sake of gripping and handling of housing 12. In addition, housing 12 includes a wall portion 20 which is provided with a weakened zone 22, FIGS. 2, 3, and 4. Wall portion 20 forms a chamber 23, FIG. 3, which is enclosed when top 14 is connected to bottom 16 during the construction of housing 12. Again, housing 12 may be formed of any suitable material, such as plastic, metal, rubber, wood, and the like.
Device 10 is also provided with a key shaft 24. Key shaft is fashioned with a first end portion 26 and a second end portion 28. First end portion 26 of key shaft 24 is accessible outside the confines of housing 12 and chamber 23. First end portion 26 of key shaft 24 also includes the necessary shapes and cuts 30 to operate a lock, such as a lock found in a vehicle, dwelling, and the like. Second end portion 28 of key shaft 24 has a section 32 which lies within chamber 23. Section 32 of second end portion 28 of key shaft 24 lies adjacent weakened zone 22 of wall portion 20. In this regard, line 34, FIG. 3, indicates the end of second end portion 28 of key shaft 24 in one embodiment of the invention. Needless to say, the embodiments depicted in the drawing, also illustrate that second end portion 28 of key shaft 24 includes an end 36 which extends outside of chamber 23 and the confines of housing 12. End 36 is also formed with an aperture 38 which may be employed to connect device 10 to a key ring or the like, (not shown). Most importantly, it must be realized that key shaft 24 is positioned to housing 12 such that a force on key shaft 24, arrow 40 of FIG. 3, will separate and move key shaft 24 away from housing 12, arrow 42 FIG. 3.
Holder 44 is also found in the present invention and is used to store medicament 46, which is depicted as a pair of pills in FIGS. 3-5. Holder 44 is supported by or connected to section 32 of second portion 28 of key shaft 24. That is to say, holder 44 lies inside chamber 23 of housing 12 in the initial configuration of device 10 depicted in FIGS. 1-3. Holder 44 may take the form of a frangible capsule 48. A retainer 50 is also employed to stabilize holder 44 within chamber 23. Retainer 50 is shown as a pair of flanges 52 and 54, FIGS. 3-5. It should be noted that flange 52 is rotatable according to directional arrow 56, FIG. 5.
In operation, device 10 is assembled such that top 14 and bottom 16 separably sandwich key shaft 24 therebetween. Key shaft 24 is held in this position to avoid relative movement between key shaft 24 and housing 12, during normal usage of device 10 in locking and unlocking operations. However, a predetermined force, directional arrow 40 of FIG. 3, will separate key shaft 24 from housing 12 to permit a sliding relationship. At this juncture first end portion 26 extends from housing 12 of device 10 and second portion 28 of key shaft 24 lies at least partially within chamber 23. In other words, section 32 of second portion 28 of key shaft 24 lies within chamber 23. A holder 44, in the form of a capsule 48, contains medicament 46. Holder 44 is motion stabilized within chamber 23 by retainer 50 in the form of flanges 52 and 54, FIGS. 3-5. Second portion 28 of key shaft 24 lies adjacent weakened zone 22 of wall portion 20, forming chamber 23 in housing 12. If one wishes to gain access to medicament 46 within capsule 48, a force is applied to first end portion 26 of key shaft 24, directional arrow 40 on FIG. 3, to move or slide key shaft 24 relative to housing 12, directional arrow 42. With reference to FIG. 4, it may be observed that capsule 48 has exited chamber 23 of housing 12 and has moved according to directional arrow 58. At this point the user may penetrate capsule 48, force arrow 60, and open the same. FIG. 5 depicts capsule 48 being opened with access to medicament 46 therewithin. It should also be seen that flange 52 of retainer 50 has been rotated to allow easy access to capsule 48. It should be noted that key shaft 24 or retainer 48 may cause the breakage of weakened zone 22 of wall 20 to allow the egress of capsule 48 from chamber 23, heretofore described. Device 10 may be hung on a key chain by the use of aperture 38 at end 36 of second end portion 28 of key shaft 24, to further convenience the user.
While in the foregoing, embodiments of the present invention have been set forth in considerable detail for the purposes of making a complete disclosure of the invention, it may be apparent to those of skill in the art that numerous changes may be made in such detail without departing from the spirit and principles of the invention.
