Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to generally to refrigerated housings and more particularly to those refrigerated housings suited for the storage of cadavers. The invention is specifically related to a rotational cadaver system which utilizes a rotational storage rack to store the cadavers. 
     It is well known that hospitals utilizes refrigerated compartments to store cadavers prior and subsequent to the performance of an autopsy. This is necessary to preserve the body and prolong the natural decomposition process which would normally take place without refrigeration. 
     Typical cadaver refrigeration units also utilize a telescoping tray assembly with each cadaver stored on an individual tray stored within the refrigeration unit. In order to remove a cadaver from such an assembly, it is typically required that an orderly or other personnel physically lift the cadaver and place it on a cart. The reverse is also true when the cadaver is to be placed in the refrigeration unit. Such activities can often be the cause of work related injuries, especially in cases where the cadaver to be moved is heavy. While numerous storage means exist, none are particularly suited for use with cadavers in a post mortem setting. Accordingly, there is a need for efficient storage and retrieval of cadavers. 
     The prior art discloses numerous refrigerated systems and rotational storage devices. For example, U.S. Pat. No. 143,059 issued on Sep. 23, 1873 to Camp discloses a refrigerator which is constructed such that the interior parts may be readily removed for cleaning. The refrigerator includes a hollow perforated shaft with four-armed plates or spiders and a plurality of swinging shelves. The shelves are pivotally mounted to the four-armed plates so that items may be readily placed or removed from the shelves. 
     U.S. Pat. No. 1,785,954 issued on Dec. 23, 1930 to Hayes discloses a dispensing refrigerator which is mainly designed to dispense bottled beverages. The refrigerator includes a rotary member which is disposed in a cooling chamber. A plurality of racks or trays are suspended to the rotary member and are capable of holding the bottles or articles placed therein. The racks are connected to the rotating member such that they assume an upright position irrespective of their location relative to the rotary member. 
     U.S. Pat. No. 2,592,038 issued on Apr. 8, 1952 to Kimsey discloses a refrigerated display case. The display case includes a plurality of supports which are circumferentially spaced. The supports pivotally suspend a plurality of food trays therefrom. 
     U.S. Pat. No. 3,269,569 issued on Aug. 30, 1966 to Brauner discloses a rotary vehicle parking apparatus. The apparatus includes a frame structure which is rotatably supported between pins or stub shafts. The frame structure has a plurality of platforms which are each adapted to support a vehicle. Means are provided for rotating the structure in order to bring each of the platforms to ground level in a successive manner. 
     U.S. Pat. No. 3,356,233 issued on Dec. 5, 1967 to De Filippis discloses a rotatable parking apparatus for motor vehicles. The apparatus includes a rotatable portion which includes a wheel housing and individual carriers that are supported by the wheel housing. The individual carriers are pivotally supported in order to facilitate loading and unloading the vehicles. 
     U.S. Pat. No. 3,927,772 issued on Dec. 23, 1975 to Borner discloses a vehicle parking and rotary elevator assembly. The assembly includes a wheel which has a pair of axially spaced, coaxial ring gears. The ring gears are supported for rotation about a common horizontal axis. Vehicle carrying platforms are pivotally suspended to the ring gears. A plurality of vehicle parking floors extend into an edgewise adjoining relationship relative to the circumferential periphery of the ring gears and at different levels relative to the common axis. Parking floor portions are arranged radially and centrally relative to the platforms. Idler rollers are used to support the ring gears at the top and bottom thereof. 
     U.S. Pat. No. 4,952,112 issued on Aug. 28, 1990 to Piacenza discloses a mechanical storage multi-level carpark the carpark includes a gantry structure formed by a set of uprights and cross-beams. The uprights and cross-beams define a space inside of which a vertical carousel structure is supported. The vertical carousel structure is further provided with car housing supports. 
     U.S.S.R. Patent # 452,730 published on December 1974 discloses a refrigerator chamber for biological testing. The chamber has a heat insulated housing and rotating sample containers and an evaporator. The heat insulated housing is cylindrical and the evaporators are evenly placed within the housing. A drive shaft rotates the container system while a plurality of arms are used to support the cradles. The cradles are hinged to the arms so that they continually occupy a horizontal position. 
     None of the prior art is seen to describe the present invention as claimed. Therefore, a rotational cadaver system which facilitates the storage and retrieval of cadavers would be beneficial.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to the Drawing, and initially to FIG. 1, there is shown a rotational storage rack 10 in accordance with the present invention. The rotational storage rack 10 includes a base 12 which has a generally rectangular shape. The base 12 is formed from a plurality of members 13 which are rigidly secured to each other. The rectangular shape of the base 12 defines two short sides and two long sides. 
     A first leg 14 is vertically positioned at about the midpoint of one of the short sides of the base 12. The first leg 14 is then secured to the corresponding short side of the base 12 by appropriate means such as a weld. The second leg 16 is similarly positioned at about the midpoint of the remaining short side of the base 12 and secured thereto. The first and second shafts 18 are respectively positioned proximate the first and second legs 14, 16 in a horizontal manner which is parallel to the long sides of the base 12. The first and second shafts 18 are then rotatably mounted to the first and second legs 14, 16. 
     A spool 20 is mounted on the first and second shafts 18. Furthermore, each of the ends of the spool 20 terminates in an outwardly extending flange 22. The flanges 22 at the ends of the spool 20 extend along a plane which is perpendicular to the centerline of the first and second shafts 18 and the spool 20. A wheel 24 is positioned at each end of the spool 20 and secured to a corresponding flange 22. Wheel 24 is seen to be comprised of a first and second plate 24(a), 24(b). The wheels 24 are also secured to the first and second shafts 18. 
     With continued reference to FIG. 1 and particular reference to FIG. 3, the wheels 24 are shown to be secured to the flanges 22 with fasteners 38. This, however is not a requirement. The wheels 24 may be secured in numerous ways including welding, which is the preferred means for securing. A plurality of branches 26 are sandwiched between first and second plates 24(a) and 24(b). Fasteners 38 such as bolts are used to secure each branch 26 between first and second plates 24(a), 24(b). Each of the wheels 24 receives the same number of branches 26. The branches 26 are oriented in a radial manner with respect to the center of their respective wheel 24. Furthermore, the wheels 24 and branches 26 are oriented and secured in such a manner that when viewed along the centerline of the first and second shafts 18, each branch 26 from the first wheel 24 is aligned with a corresponding branch 26 from the second wheel 24. An arm 30 is pivotally attached to each of the branches 26 via a pin 28. A number of trays 34 are provided for supporting the items being stored. The trays 34 are designed with a predetermined length corresponding to the distance between the pairs of arms 30 in the first and second wheel 24. Each tray 34 further includes a plurality of apertures disposed along two of its sides. 
     A plurality of receptors 30(a) are rigidly secured to the free end of each arm 30 in order to support the trays 34. As illustrated in FIGS. 1 and 3, the receptors are generally hook shaped. This allows the receptors 30(a) to insertably engage the apertures contained in the tray 34. Accordingly, each tray 34 is supported by one arm 30 from the first wheel 24 and a corresponding arm 30 from the second wheel 24. As seen by intuitively examining the different branches and arms 26, 30 in FIG. 3, the pins 28 allow the arms 30 to pivot with reference to the branches 26. As the first and second shafts 18 are rotated, they correspondingly rotate the wheels 24. The arms 30, in turn pivot in accordance to the degree of rotation so as to continually maintain the trays 34 in a horizontal manner, thereby not spilling the contents of the trays 34. 
     FIG. 2 illustrates a preferred embodiment of the wheel of the present invention. The wheel 50 is seen to be comprised of a first and second plate 52, 54. A plurality of branches 56 are sandwiched between the first and second plates 52, 54. Fasteners 38 such as bolts are used to secure each branch rigidly between the two plates 52, 54. Alternatively, the branches 56 could be welded to the plates 52, 54. Each branch 56 is positioned in a radial manner with respect to the center of the first and second plates 52, 54. The first and second (not shown) shafts 18 extend through each wheel 50. The second plate 54 of the wheel 50 is secured to the flange 22 of the spool 20 by a plurality of fasteners 38. The first and second plates 52, 54 of the wheel 50 are respectively secured to the first and second shafts 18, preferably by welding. Each branch 56 also includes an arm 60 which is pivotally mounted thereto via a pin 58. Each arm further includes a plurality of receptors 60(a) which are generally hook shaped in order to effectuate support of the tray 34. 
     Turning to FIG. 4, a rotational cadaver system 100 which utilizes a rotational storage rack 110 is illustrated. The rotational cadaver system 100 additionally includes a refrigerated housing (not shown), means for removing the contents of the rotational storage rack, a cadaver carrier 166, and an autopsy cart (not shown). 
     The rotational storage rack 110 of the system includes a base 112 which has a generally rectangular shape and a hollow interior. The rectangular shape of the base 112 accordingly defines two long sides and two short sides. The rotational storage rack 110 also includes a first and second leg 114, 120 which are each vertically positioned at about the midpoint of each of the short sides of the base 112 and appropriately secured thereto by welding. A first and second shaft 122 are horizontally positioned proximate the first and second legs 114, 120. As seen in FIG. 4, the orientation of the first and second shafts 122 is parallel to the long sides of the base 112. The first and second shafts 122 are then rotatably mounted to the first and second legs 114, 120, respectively. 
     As seen more particularly with reference to FIG. 5, a plurality of bearings 118 is used to facilitate the rotational mounting of the first shaft 122. A bearing mount 116 is used to secure the bearings 118 to the first leg 114. Each bearing 118 includes an outer race and an inner race (not shown). The outer race of each bearing 118 is rigidly secured to the bearing mount 116. The first shaft 122 is then mounted within the inner race of the bearings 118 so that it may rotate with the inner race. A plurality of fasteners 144 are used to secure the bearing mount 116 to the first leg 114. The second shaft 122 is similarly mounted to the second leg 120. 
     A spool 124 is mounted on the first and second shafts 122. As seen in FIG. 4, the first and second shafts penetrate a predetermined distance within the spool 124. Each of the ends of the spool 124 further terminates in an outwardly extending flange 126. A first wheel 130 is positioned at the end of the spool 124 proximate the first leg 114 and appropriately secured with fasteners 144. Similarly, a second wheel 146 is positioned at the opposite end of the spool 124, proximate the second leg 120, and secured to the corresponding flange with fasteners 144. 
     A plurality of branches 136 are secured to the first and second wheels 130, 146. As is apparent in FIG. 4, each of the wheels 130, 146 receives an equal number of branches 136. The branches 136 are further aligned in a radial manner with respect to their corresponding wheel, such that each branch 136 would pass through the midpoint of its corresponding wheel. Furthermore, the first and second wheels 130, 146 are cooperatively aligned such that when viewed along the centerline of the first and second shafts 122, each branch 136 from the first wheel 130 is seen to be aligned with a branch 136 from the second wheel 146. This arrangement also defines corresponding pairs of branches 136 in the rotational storage rack 110. 
     Referring again to FIG. 5 with particularity, the first wheel 130 is seen to be comprised of a first and second plate 132. Each of the two plates 132 is positioned on opposite sides of the branches 136 corresponding to the first wheel 130. Although various equivalent means exist, fasteners 144 are used to secure the first and second plates 132 and the branches 136 as a unitary structure. This preferred arrangement of the first wheel 130 allows the flange 126 of the spool 124 to be rigidly secured to one of the plates 132. Furthermore, the first shaft 122 is secured to each plate 132 of the first wheel 130 preferably by welding. With continued reference to FIG. 4, an arm 140 is shown attached to the end of each of the branches 136. The arms 140 are attached in a pivotal manner by means of a pin 138. The pivotal connection of the arms 140 insures that they occupy a vertical orientation regardless of their radial position with respect to the first and second wheels 130, 146. The arms 140 generally retain this orientation even as the first and second shafts 122, and consequently the first and second wheels 130, 146, are rotated. Furthermore, each arm 140 associated with the first wheel 130 is paired with an arm 140 associated with the second wheel 146. 
     A number of trays 160 are provided for supporting the cadavers being stored on the rotational storage rack 110. The length of the trays 160 is predetermined to be generally equivalent to the distance between each corresponding pair of arms 140 on the first and second wheels 130, 146. Thus, each tray 160 is partially supported at one end by an arm 140 from the first wheel 130 and at the other end by a corresponding arm 140 from the second wheel 146. While various means exist to provide support of the trays 160, the arms 140 are preferred to include a receptor 142 rigidly secured to their ends. The receptors 142 are positioned so that they support the trays 160 in a generally flat orientation. As illustrated in FIG. 4, the receptors 142 are generally hook shaped. In order effectuate this support, each tray 160 includes a plurality of apertures corresponding to the receptors 142. Thus, the receptors 142 of each arm 140 insertably engage the apertures in the tray 160. Since the nature of the connection of the arms 140 to the branches 136 forces the arms 140 to occupy a vertical orientation, the receptors 142 accordingly cause the trays 160 to maintain a flat orientation regardless of their position on the rotational storage rack 110. Each tray 160 further includes two channels 162 superimposed to the bottom surface thereof, with the channels 162 being spaced apart by a predetermined distance. 
     The second shaft 122 is secured to the second leg 120 in a manner similar to that of the first leg 114, as illustrated in FIG. 6. A bearing mount 116 is used to secure a plurality of bearings 118 to the second leg 120 via fasteners 144. The bearing mount 116 retains the outer races of the bearings 118 in a fixed position while allowing the inner races to rotate freely. The second shaft 122 is then mounted within the inner races of the bearings 118 and allowed to rotate in accordance therewith. FIG. 6 also shows a mechanical drive 145 system which is the preferred method of turning the rotational storage rack 110. The mechanical drive system includes a motor 146 and means for transmitting the output of the motor 146 to the second shaft 122. The motor 146 is rigidly secured to the second leg 120. The motor 146 also includes a drive shaft which extends therefrom. A trans reduction case 147 receives the drive shaft of the motor 146 and serves as a means of reducing the rotational velocity of the motor 146. The trans reduction case 147 includes an output shaft 148 which has a drive gear 150 mounted thereon, as seen with additional reference to FIG. 7. In preferred embodiments of the invention, the trans reduction case 147 achieves a 1200:1 reduction ration. The second shaft 122 includes a driven gear 152 mounted thereon. A chain 154 is used to interrelate the output of the output shaft 148 to the driven gear 152 and consequently the second shaft 122. As seen in the illustration, the drive gear 150 and the driven gear 152 each include a plurality of sprockets in order to mesh with the chain 154. It should be appreciated, however, that various other transmission means exist, such as a system employing a plurality of pulleys and a belt. 
     In preferred embodiments of the invention, a third leg 156 is also provided for further supporting the second shaft 122. The third leg 156 is positioned in a similar manner as the first and second legs 114, 120 beneath the second shaft 122. A support block 155 is rigidly secured to the second and third legs 120, 156. The motor 146 is subsequently secured to the support block 155. A bearing mount 116 secures a bearing 118 to the third leg 156 via fasteners 144. The terminal end of the second shaft 122 is mounted on the inner race of the bearing 118 on the third leg 156. The third leg 156 is provided in order to relieve some of the stress which is placed on the bearings 118 mounted on the second leg 120. The stresses arise due to the tension placed on the second shaft 122 from the drive train. The motor also includes switching means (not shown) for selectively providing power thereto, and consequently turning the first and second shafts 122 and the first and second wheels 130, 146 in order to position a selected cadaver for removal. Furthermore, braking means are provided so that the rotational storage rack 110 will not move while the power is selectively switched off. 
     FIG. 8 illustrates the stacker 178 of the rotational cadaver system 100. The stacker includes a plurality of casters 182 to facilitate movement along the ground. The stacker 178 also includes two pronged extensions 180 for supporting the trays 160. Each pronged extension 180 has a tapered end 184. The distance between each prong 180 of the stacker 178 corresponds to the distance between the channels 162 of the trays 160. In order to remove the trays from the receptors 142, the prongs 180 of the stacker 178 engage the channels 162 of the trays 160. The tapered ends 184 help facilitate and guide the prongs 180 into the channels 162. As illustrated by the phantom lines in FIG. 8, the stacker 178 is capable of vertically adjusting the position of the prongs 180 so that it may remove or place the trays 160 from or onto the receptors 142. 
     Once removed from the rotational storage rack 110, the tray 160 may be placed on a cadaver carrier 166, as illustrated in FIG. 9. The cadaver carrier 166 includes a frame 170 which is formed from a plurality of rigid members. The frame 170 has a generally rectangular shape which defines two long sides and two short sides. The cadaver carrier 166 also includes four upstanding legs 172, each of which is attached at one corner of the frame 170 in a vertical manner. Casters 168 are attached to the lower ends of each upstanding leg 172 in order to facilitate movement. A plurality of receptors 174 are secured to the short sides of the frame 170. The receptors 174 allow the tray 160 to be placed securely on the cadaver carrier 166. The cadaver carrier 166 also includes a rigid cover 184 and a shroud 186. The cover 184 and shroud 186 are used to give the perception that a box or crate is being transported as opposed to a cadaver. 
     Turning again to FIG. 4, the rotational storage rack 110 is seen to include a pathway generally indicated by the numeral 198. The pathway 198 is sized to correspond to the width of the stacker 178. In operation, the stacker 178 is moved into the pathway 198 in order to place or remove a tray 174. As the stacker 178 enters the pathway, it is forced into an alignment which facilitates the engagement of the prongs 180 with the channels 172 of the trays 174. Once removed from the rotational storage rack 110, the tray 160 may be taken to the location of the autopsy and placed on an autopsy cart 200, which may be seen more particularly with reference to FIG. 10. The autopsy cart 200 is then secured to the autopsy station. The autopsy cart 200 includes a frame 210 which is formed from a plurality of rigid members. The frame 210 has a generally rectangular shape which defines two long sides and two short sides. The autopsy cart 200 also includes 2 sets of two upstanding legs 212 and 212(a), each of which is attached at one corner of the frame 210 in an vertical manner. Upstanding legs 212(a) are most preferably 1 inch shorter than upstanding legs 212. As such, tray 160 is sloped in a downward direction toward latching mechanism 332 and autopsy station 250, for purposes of facilitating the drainage of fluids arising during the course of an autopsy. Casters 214 are attached to the lower ends of each upstanding leg 212 in order to facilitate movement. A plurality of receptors 216 are secured to the short sides of the frame 210. The receptors 174 allow the tray 160 to be placed securely on the autopsy cart 200. The autopsy cart 200 further includes means for securing it to various types of autopsy stations, including stand-alone and wall mounted units.

     FIG. 16 outlines the various steps associated with processing the cadaver with the rotational cadaver system 100. The first step of the process is to store the cadaver in a refrigerated housing for a predetermined length of time, or until an appropriate official is ready to perform the autopsy. When appropriate, the cadaver is removed from the refrigerated housing. In order to remove the proper cadaver, it may be necessary to turn the rotational storage stack so that the tray containing the required cadaver is positioned for removal. A switch is used to selectively provide power to the motor thereby turning the rotational storage rack. The stacker is then moved into the pathway of the rotational storage rack and aligned with the tray. The prongs of the stacker are inserted into the channels of the tray and raised vertically so that the tray is lifted from the receptors. Next, the tray containing the cadaver is placed on an autopsy cart. The tray with cadaver is then transported by means of the autopsy cart to the location where the autopsy is to be performed. The autopsy cart is then positioned near a stand alone or wall mounted autopsy station, and secured thereto. Finally, the autopsy is performed. 
     While the invention has been described with reference to selected preferred embodiments, it should not be limited to those embodiments. Rather, many modifications and variations will become apparent to those skilled in the art without departure from the scope and spirit of this invention as defined in the appended claims. For example, one of ordinary skill in the art will readily appreciate that a second rotational storage rack could be placed in a side by side alignment with a first rotational storage rack, wherein both racks are driven by the same motor.
