As best illustrated in FIGS. 1 through 7, the landing gear elevator 100 (hereinafter invention) is further comprised of a motor 101 that is configured to connect to a trailer landing gear rod 200 in order to raise and lower a respective tractor-trailer landing gear leg 201. It shall be noted that in the prior art, a tractor-trailer typically includes a pair of the tractor-trailer landing gear legs 201. Moreover, the landing gear legs move up and down in concert upon rotation, either clockwise or counterclockwise, of the trailer landing gear rod 201. The invention 100 is configured to rotate the trailer landing gear rod 201 in order to raise or lower the tractor-trailer landing gear legs 201.
The motor 101 includes a rechargeable powering member 102 that is secured underneath the motor 101, and provides electrical power to the invention 100. Moreover, the motor 101 includes a set of band members 103 that encircle the motor 101 and extend downwardly to support the rechargeable powering member 102 underneath the motor 101.
The motor 101 includes a top handle 104 that extends upwardly from the motor 101 in order to provide a handle with which to grasp the invention 100 from directly above the motor 101. The top handle 104 is a “U”-shaped component that is rigidly affixed to the sides of the motor 101 via a fastening member 105 comprising a bolt, screw, nail, rivet, etc.
Referring to FIG. 4, the invention 100 includes a left handle 106 and a right handle 107. Both the left handle 106 and the right handle 107 are positioned to a rear portion of the invention 100, and are able to pivot about a pin 108. Both the left handle 106 and the right handle 107 are each able to pivot from a perpendicular orientation to a parallel orientation with a main motor shaft axis 300. The main motor shaft axis 300 is concentrically aligned with a main motor shaft 109 that is positioned on an opposing end of the motor 101 with respect to the left handle 106 and the right handle 107.
Positioned in between the pins 108 of the left handle 106 and the right handle 107 is a power/speed control switch 110. The power/speed control switch 110 is responsible for adjusting the output of RPMS of the main motor shaft 109. The power speed control switch 110 is in wired communication with the motor 101 as well as with the rechargeable powering member 102. Moreover, the power speed control switch 110 is in wired communication with an on/off/down push button 111 that is located on the right handle 107. The power speed control switch 110 is in wired communication with an on/off/up push button 112 that is located on the left handle 106. It shall be noted that the on/off/down push button 111 is located on a top right handle surface 113 of the right handle 107 such that the on/off/down push button 111 is out of the way of the right handle 107 when in use. It shall also be noted that the on/off/up push button 112 is located on a top left handle surface 114 of the right handle 106 such that the on/off/up push button 112 is out of the way of the left handle 106 when in use.
Output of the main motor shaft 109 is dictated upon depression of either the on/off/down push button 111 or the on/off/up push button 112. The main motor shaft 109 is in mechanical connection with a gear reducer 120. The gear reducer 120 simply reduces the RPM out of the main motor shaft 109 in exchange for a greater amount of torque. Referring to FIG. 4, the main motor shaft 109 includes a first gear 121; whereas the gear reducer 120 includes a second gear 122. The second gear 122 is greater in size than the first gear 121. Moreover, the second gear 122 is coupled to a gear reducer drive shaft 123. The gear reducer 120 includes a first gear reducer cover 124 and a second gear reducer cover 125, which provide protection of the inner workings of the gear reducer 120 from environmental conditions.
The gear reducer drive shaft 123 connects with a drive-coupling member 130. The drive-coupling member 130 is configured to attach to the landing gear rod 201. Moreover, the drive-coupling member 130 includes a gear reducer receiver 131 on a first distal end 132 and a landing gear receiver 133 at a second distal end 134. The landing gear receiver 133 includes a square-shape that is configured to receive the landing gear rod 201. Moreover, the drive-coupling member 130 includes a set of lock holes 135 that enable a first clamp member 136 to extend across both the drive coupling member 130 as well as the landing gear rod 201. The landing gear rod 201 includes a landing lock hole 202. The first clamp member 136 connects with a second clamp member 137 in order for a locking member 138 to lock both the first clamp member 136 and the second clamp member 137 in place with respect to the drive-coupling member 130. Moreover, a key 139 is included in order to lock and unlock the locking member 138/Referring to FIG. 1, it shall be noted that a pin member 140 may be used to secure the drive-coupling member 130 to the landing gear rod 201 in lieu of the first clamp member 136 and second clamp member 137 and locking member 138 as depicted in FIG. 7.
The rechargeable powering member 102 is unique to the invention 100 in that the band members 103 may be removed as needed in order to replace the rechargeable powering member 102. Moreover, the rechargeable powering member 102 is essentially a large rechargeable battery that includes an electrical plug receptacle 150 on a first surface 151. The electrical plug receptacle 150 enables an electrical plug 400 to connect and provide electricity from a standard wall outlet 401 in order to recharge the rechargeable powering member 102. Moreover, the rechargeable powering member 102 includes an adaptor plug receptacle 152 that enables a cigarette lighter power cord 402 to deliver electricity to the rechargeable powering member 102 via a cigarette plug 403 that is typical of a vehicle.
Referring to FIG. 8, the invention 100 may utilize a handle coupling 500 that is configured to attach to a landing gear handle 501 of a landing gear 200. The landing gear handle 501 is commonly seen on tractor-trailers, and is manually rotated in order to raise or lower the landing gear 200. The handle coupling 500 contours to attach itself at a first elbow 502 of the landing gear handle 501. The handle coupling 500 includes a handle coupling gear reducer receiver 503 that is concentrically aligned with a first armature span 504 of the landing gear handle 501. Moreover, the handle coupling gear reducer receiver is able to connect with the gear reducer drive shaft 123, and which enables the invention 100 is able to rotate the landing gear handle 501 as opposed to manual rotation.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention 100, to include variations in size, materials, shape, form, function, and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention 100.
It shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
