DETAILED DISCUSSION

FIGS. 1-28 are various views of a pivoting system 10 for a device 20 mounted on a cargo platform 30. A cargo pivot 32 pivotably couples the cargo platform 30 with a cargo support 34. The cargo support 34 is coupled to a structure 12. The cargo pivot 32 pivotably couples the cargo platform 30 between a general vertical position 40 as seen in FIGS. 15-28 and a general horizontal position 42 as seen in FIGS. 1-14. The cargo platform 30 has a first side 50, a second side 52 and extends between a proximal end 54 and a distal end 56.

The structure 12 may include a trailer hitch adapter 14 that is coupled to a vehicle (not shown). Alternatively, the structure may include a static mount on a stationary structure. The cargo platform 30 may include a mobility vehicle cargo platform or an external mounted mobility device 22 for transporting a personal mobility device (not shown). The external mounted mobility device 22 facilitates transportation of the personal mobility device when the cargo platform 30 is in the general horizontal position 42. When the personable mobility device is not loaded onto the external mounted mobility device 22, the cargo platform 30 may be positioned into the general vertical position 40.

The pivoting system 10 pivotably couples an electronic device 60 with the cargo platform 32 and pivots the electronic device 60 during pivoting of the cargo platform 30 between the general vertical position 40 and the general horizontal position 42. The electronic device 60 may include a proximity sensor 62, a camera 64, an illumination device 66 and/or a sound emitting device 68. The electronic device 60 receives an electric current 70. The pivoting system 10 may increase effectiveness and improve safety by maintaining the electronic device 60 in a general horizontal position when the cargo platform 30 is positioned anywhere between the general vertical position 40 and the general horizontal position 42.

The pivoting system 10 comprises a base 80 coupled to the cargo support 34. A frame 82 is coupled to the cargo platform 30. Preferably, the frame 82 is coupled to the distal end 56 of the cargo platform 30 such that the electronic device 60 has a higher elevation in the general vertical position 40 and the electronic device 60 is not obstructed by the cargo platform 30 in the general horizontal position 42.

A linkage rod 90 extends between a proximal end 92 and a distal end 94 and slidably engages with the cargo platform 30 relative to the proximal end 54 and the distal end 56 of the cargo platform 30. The linkage rod 90 may further include a perpendicular linkage rod 96 for displacing the proximal end 92 and the distal end 94 of the linkage rod 90 relative to the first side 50 and the second side 52 of the cargo platform 30.

A proximal pivot 100 pivotably couples the proximal end 92 of the linkage rod 90 to the base 80. A proximal arm 110 may be coupled to the proximal end 92 of the linkage rod 90. The proximal pivot 100 pivotably couples the proximal arm 110 to the base 80. A proximal groove 112 is in the proximal arm 110 for slidably engaging the proximal pivot 100 during pivoting of the electronic device 60.

The proximal pivot 100 and the cargo pivot 32 define a proximal linkage 120 having a proximal distance 122 therebetween. More specifically, the proximal pivot 100 and the cargo pivot 32 define proximal vertical distance 124 and a proximal horizontal distance 126 therebetween.

A device pivot 140 pivotably couples the electronic device 60 to the frame 82. A distal pivot 142 pivotably couples the distal end 94 of the linkage rod 90 to the electronic device 60. More specifically, a housing 144 may be pivotably coupled to the frame 82. The housing 144 includes a housing chamber 146 for receive the electronic device 60. The housing 144 protects the electronic device 60 from damage from foreign or outside objects. The distal pivot 142 may pivotably couple the distal end 94 of the linkage rod 90 to the housing 142.

The distal pivot 142 and the device pivot 140 define a distal linkage 150 having a distal distance 152 therebetween. More specifically, the distal pivot 142 and the device pivot 140 define a distal vertical distance 154 and a distal horizontal distance 156 therebetween.

A distal groove 170 may be positioned in the electronic device 60 for slidably engaging the device pivot 140 during pivoting of the electronic device 60. Alternatively, the distal groove 170 may be positioned in the housing 144 for slidably engaging the device pivot 140 during pivoting of the electronic device 60. More specifically, a channel body 172 may be coupled to the distal end 94 of the linkage rod 90. The channel body 172 defining a distal groove 170. A coupling pin 174 traverses the distal groove 170 and couples the housing 144 to the linkage rod 90. The coupling pin 174 slidably engages the distal groove 170 during pivoting of the electronic device 60.

The proximal distance 122 and the distal distance 152 cause pivoting of the electronic device 60 between the general vertical position 40 and the general horizontal position 42 for defining a lower general horizontal position 180 in the electronic device 60 in the general horizontal position 42 and an upper general horizontal position 182 in the electronic device 60 in the general vertical position 40.

Furthermore, the proximal pivot 100, the distal pivot 142 and the device pivot 140 causes pivoting of the electronic device 60 between the general vertical position 40 and the general horizontal position 42 for defining the lower general horizontal position 180 in the electronic device 60 in the general horizontal position 42 and the upper general horizontal position 182 in the electronic device 60 in the general vertical position 40.

The base 80 may include a base groove 200. The base groove 200 defines a proximal linkage adjustment 202 having a proximal distance adjustment 204 in the proximal distance 122. The proximal distance adjustment 204 defines an angular adjustment 206 in the electronic device 60 in the lower general horizontal position 180 and the upper general horizontal position 182. More specifically, the base 80 includes a vertical base groove 210 for changing the proximal vertical distance 124 of the proximal pivot 100 relative to the cargo pivot 34 for defining a proximal linkage adjustment 202 having a proximal distance adjustment 204. The proximal distance adjustment 204 defines an angular adjustment 206 for alternating the angular orientation 208 of the electronic device 60 in the lower general horizontal position 180 and the upper general horizontal position 182.

As best shown in FIGS. 9-11 and 23-25, a first proximal linkage adjustment 212 results in the electronic device 60 having a general level orientation 214 when the cargo platform 30 is positioned within the general vertical position 40. Alternatively, as best shown in FIGS. 12-14 and 26-28, a second proximal linkage adjustment 216 results in the electronic device 60 having a general descending position 218. The proximal linkage adjustment 202 may be beneficial by adjusting the angular orientation of the electronic device 60 for increasing the performance of the electronic device 60. Furthermore, the proximal linkage adjustment 202 may be beneficial for utilizing the pivoting system 10 on various cargo platforms 30 having different sizes. For example the larger the cargo platform 30 the more the electronic device 60 needs to be adjusted towards the ground so that the field of view is in the proper position. It should be noted, that the proximal linkage adjustment 202 primarily adjusts the angle of the electronic device 60 in the top position as shown in FIGS. 23, 24, 26 and 27 and does little to adjust the electronic device 60 in the lower position as shown in FIGS. 9, 10, 12 and 13.

The present invention further incorporates a method for pivoting a device 20 mounted on a cargo platform 30. A cargo pivot 32 pivotably couples the cargo platform 30 with a cargo support 34. The cargo support 34 is coupled to a structure 12. The cargo pivot 32 pivotably couples the cargo platform 30 between a general vertical position 40 and a general horizontal position 42. The method comprises the steps of coupling a frame 82 to the cargo platform 30. An electronic device 60 is coupled to the frame 82 for receiving an electric current 70 and sending electric signals 70. The electronic device 60 pivots relative to the frame 82 for causing pivoting of the electronic device 60 relative to the frame 82 between the general vertical position 40 and the general horizontal position 42 for defining a lower general horizontal position 180 in the electronic device 60 in the general horizontal position 42 and an upper general horizontal position 182 in the electronic device 60 in the general vertical position 40.

The electronic device 60 may be pivoted relative to the frame 82 by a mechanical linkage 90. Alternatively, the electronic device 60 may be pivoted relative to the frame 82 by an electronic inclinometer that is electrically coupled to a motor that pivots the electronic device 60.

The present disclosure includes that contained in the appended claims as well as that of the foregoing description. Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
