     FIELD OF THE INVENTION 
     The present invention provides a means for facilitating the storage of suction hoses with respect to an emergency vehicle. Such hoses are commonly somewhat rigid, and as such, cannot be coiled or otherwise condensed dimensionally when stored with respect to an emergency vehicle such as a fire truck. As such, these suction hoses need to remain generally oriented in a longitudinal position without any coiling or folding thereof. The present invention provides a unique construction for storing such devices horizontally above the body of an emergency vehicle such as a fire truck or trailer while allowing controlled movement of the supporting mechanism for holding and retaining of the suction hose between a lower position for replacement or removal, and an upper position for secure storage when the emergency vehicle is moving, often at high speeds to the location of an emergency situation.

     DETAILED DESCRIPTION OF THE INVENTION 
     In the drawings, like numerals indicate like elements throughout. Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. The following describes preferred embodiments of the present invention. However, it should be understood, based on this disclosure, that the invention is not limited by the preferred embodiments described herein. 
     Referring to  FIGS. 1-6 , a storage apparatus  10  in accordance with an exemplary embodiment of the invention will be described. The storage apparatus  10  is for the purpose of retaining a somewhat rigid hose  100  (see  FIG. 4 ), such as a conventional suction hose, on top of an emergency vehicle  2 , such as a fire truck or fire trailer. Typically, the fire truck  2  or equivalent includes a generally horizontally extending vehicle body top  4  and a generally vertically extending vertical body panel  6  thereadjacent. The storage apparatus  10  secures the hose  100  such that it is moveable between a storage position (see  FIG. 2 ) on the vehicle body top  4  and a loading/unloading access position (See  FIG. 1 ) lowered from the vehicle body top  4  to facilitate rapid removal and replacement thereof as needed. 
     In the illustrated embodiment, the storage apparatus  10  includes a support carriage  12  with a support tray  14  secured to the upper facing surface thereof. The support carriage  12  is the main structural member which supports the hose  100  thereabove. The support tray  14  is preferably of aluminum material and is approximately L-shaped in cross-section. The L-shaped configuration includes a horizontal support surface  13  extending along the support carriage  12  and a side wall  15  with a hose receiving area  16  defined therewithin. The side wall  15  helps to prevent side to side movement of the hose  100  when it is supported by the storage apparatus  10 . A handle  18  is pivotally connected to the rearward end of the support carriage  12  and a guide wheel  26  is provided on a lower surface toward the forward end thereof, both to facilitate movement of the carriage  12  as will be described in more detail hereinafter. 
     One or more retaining means may be included to further secure the hose  100  within the receiving area  16 . At the forward end, toward the cab of the fire truck  2 , a v-shaped flexible retaining member  20  extends from the side wall  15 . The v-shaped retaining member  20  is configured to extend into an open end of the hose  100 . The length at which the v-shaped retaining member  20  extends from the forward end of the support tray  14  provides a tolerance to facilitate hoses  100  of varying lengths. At the rearward end of the support tray  14 , a generally flat retaining member  22  extends from the side wall  15  and across the receiving area  16 . The flat retaining member  22  is preferably flexible to allow movement thereof to facilitate removal and insertion of the hose within the receiving area  16 .  FIG. 4  shows additional optional retaining means in the form of straps  24 , bungee cords or the like which extend from the side wall  15  to the support surface  13  to further retain the hose  100  in the receiving area  16 . The straps  24  are preferably positioned toward the rearward end of the support tray  14  such that they are easily accessible when the storage carriage  12  is in the loading/unloading access position. 
     Referring to  FIGS. 4-6 , to facilitate movement and tilting of the storage carriage  12  from the storage position to the access position, the storage apparatus  10  includes a tilting assembly  30 . The tilting assembly  30  includes a base plate  32  which is secured to the vehicle body top  4  adjacent to the vertical body panel  6 . A pair of spaced apart pivot mounts  34  and  36  extend upward from the base plate  32  and pivotally supported the tilting guide track  40 . Each pivot mount described herein may be a single mount or more than one mount, for example, two mounts laterally separated to support both sides of the guide track  40 . The rearward end of the guide track  40  includes a pivot mount  44  which aligns with and is pivotally connected to the pivot mount  34  of the base plate  32  such that the guide track  40  is pivotal relative to the fixed base plate  32 . The forward end of the guide track  40  includes a second pivot mount  46  and in the illustrated embodiment, a telescoping member  42  extends between the mounts  36  and  46  to assist in maintaining proper alignment of the tilting track  40 . It is further contemplated that the telescoping member  42  may include an internal pneumatic chamber (not shown) which facilitates dampening of movement of the storage carriage  12  when moving between the storage position and the access position to prevent sudden or rapid unwanted movement thereof. Furthermore, a spring can be configured within the telescoping member  42  which is operative to exert a continuous retracting force on the telescoping member  42 , as indicated by arrow A in  FIG. 5 , to provide an assisting force in support of the manual lifting of the support carriage  12  from the access position to the storage position. 
     An exemplary embodiment of the guide track  40  is illustrated in  FIG. 6 . The guide track  40  includes a base surface  41  with a pair of opposed side walls  43 . A return  45  extends inward from each side wall  43  such that a guide slot  47  is defined between the base surface  41 , the side walls  43  and the returns  45 . The guide slot  47  is sized such that the support carriage  12  is retained therein while remaining moveable therealong. 
     When the storage carriage  12  is moved to the storage position, the tiling assembly  30  remains fixed and the storage carriage  12  moves forward relative thereto. To support the forward end of the storage carriage  12  and prevent lateral movement thereof, one or more saddle supports  50  are preferably secured to the vehicle body top  4  forwardly of the tilting assembly  30 . Each saddle support  50  includes a pair of spaced apart horizontal support shoulders  52  with a respective retaining wall  54  extending upward therefrom such that a carriage receiving slot  56  is defined. When in the storage position, the carriage  12  is vertically supported on the shoulders  52  and prevented from lateral movement by the retaining walls  54 . 
     To limit movement of the support carriage  12  forwardly with respect to the vehicle body  2 , an end bracket  60  is preferably positioned at the approximate forwardmost position of the support carriage  12  when carriage  12  is in the storage position. This end bracket  60  preferably includes an extension  62  extending from the vehicle body top  4  and an upper tab  64  extending therefrom, substantially parallel to the vehicle body top  4  such that a docking cavity  66  adapted to receive the forwardmost portion of the support carriage  12  is defined. 
     An exemplary movement of the storage carriage  12  from the storage position of  FIG. 2  to the access position of  FIG. 4  will be described. Manual movement of the support carriage  12  is enhanced by the inclusion of a handle  18 . This handle  18  is preferably pivotally connected with respect to the rearmost portion of the support carriage  12  and in this manner the handle  18  can be grasped by a single emergency person for powering movement of the storage apparatus of the present invention from the storage position to the access position as shown in  FIG. 4  or in the opposite direction for movement from the access position to the storage position. 
     When the support carriage  12  is in the storage position, the handle  18  be capable of extending downwardly parallel to and immediately adjacent to the vertical body panel  6  which is preferably the rear vertical facing of the fire tuck or other emergency vehicle. Preferably a handle securement bracket  70  is mounted to the rear vertical body panel  6  for the purpose of securing the handle  18  in place and helping to secure the storage apparatus  10  with respect to the emergency vehicle  2 . 
     To move the storage carriage  12  from the upper storage position to the access position, a user grasps the handle  18  and moves the support carriage  12  longitudinally as indicated by arrow B in  FIG. 3 . During this initial stage of movement, the carriage  12  moves within the guide slot  47  with much of the weight still supported on the vehicle by contact of the guide wheel  26  thereon and contact of the carriage with the saddle supports  50 . As the support carriage  12  is moved further rearwardly relative to the guide track  40 , the center of gravity of the support carriage will pass the guide track  40  and the guide track  40  will begin to naturally pivot such that the rearward end of the storage carriage  12  moves downward as indicated by arrow C in  FIG. 4 . The user can assist the motion with the handle  18 . With the storage carriage  12  in the access position, the user can easily access the hose  100 . 
     When it is desired to store the hose  100 , it is positioned in the receiving area  16  while the storage carriage  12  is in the access position. The user then uses the handle  18  to move the carriage  12  forward with the carriage  12  sliding in the guide slot  37  of the guide track  40 . During the initial movement, the guide track  40  can remain pivoted such that the user does not have to push forward and lift at the same time. Once the center of gravity of the storage carriage  12  reaches the guide track  40 , the guide track  40  will naturally pivot toward the storage position. Pneumatics, springs or the like in the telescoping member  42  may assist with such pivoting. 
     T These and other advantages of the present invention will be apparent to those skilled in the art from the foregoing specification. Accordingly, it will be recognized by those skilled in the art that changes or modifications may be made to the above-described embodiments without departing from the broad inventive concepts of the invention. It should therefore be understood that this invention is not limited to the particular embodiments described herein, but is intended to include all changes and modifications that are within the scope and spirit of the invention as defined in the claims.
