The disclosure relates to steering devices and more particularly pertains to a new steering device for manually moving and steering a trailer.
An embodiment of the disclosure meets the needs presented above by generally comprising a trailer. A mount is structured to be movably coupled to the trailer. A first actuator is coupled to the mount. The first actuator positions the mount between a raised position and a lowered position. A pair of wheels is coupled to the mount. The wheels may abut a support surface when the mount is positioned in the lowered position. A motor is coupled to the mount. The motor is mechanically coupled to the wheels. The motor may rotate the wheels. The wheels urge the trailer along the support surface. A second actuator is coupled between the mount and the wheels. The second actuator may position the wheels at a selected angle with respect to the mount so the trailer may be steered. A control is coupled to the mount. The control is electrically coupled to the first actuator, the second actuator and the motor. The control may actuate and de-actuate the first and second actuators and the motor.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A plurality of arms 22 is each movably coupled to and extends rearwardly from a back side 24 of the perimeter edge 16 of the mount 14. The plurality of arms 22 comprise a pair of lower arms 26 and an upper arm 28. The upper arm 28 has a centrally positioned bend 30 thereon. Moreover, the upper arm 28 has a U-shape. A coupling 32 is coupled to and extends upwardly from the top side 18 of the mount 14. The bend 30 on the upper arm 28 is movably coupled to the coupling 32. Each of the lower arms 26 is positioned proximate the bottom side 20 of the mount 14.
A plurality of gussets 34 is each movably coupled to a distal end 36 of an associated one of the arms 22 with respect to the mount 14. The distal ends 36 of the upper arm 28 are positioned proximate an uppermost end 38 of the gussets 34. Additionally, the distal ends 36 of the lower arms 26 are positioned proximate a lowermost end 40 of the gussets 34. The gussets 34 are each coupled to a front side 42 of the trailer 12. The mount 14 is movably coupled to the trailer 12.
A first actuator 44 is provided. The first actuator 44 is elongated between a topmost end 46 and a bottommost end 48 of the first actuator 44. The bottommost end 48 of the first actuator 44 is coupled between the lower arms 26. Additionally, the first actuator 44 extends upwardly through the U-shape of the upper arm 28. A pair of gussets 34 is coupled between the first actuator 44 and the front side 42 of the trailer 12. Moreover, the first actuator 44 positions the mount 14 between a raised position and a lowered position with respect to the trailer 12. The first actuator 44 may be an electrical actuator of any conventional design.
A wheel shaft 50 is provided. A top end 52 of the wheel shaft 50 extends upwardly through the top 18 and bottom 20 sides of the mount 14. The wheel shaft 50 is rotatably coupled to the mount 14. An axle 54 is coupled to a bottom end 56 of the wheel shaft 50. The axle 54 forms a T-shape with respect to the wheel shaft 50.
A pair of wheels 58 is each rotatably coupled to opposite ends 60 of the axle 54. The wheels 58 may abut a support surface 62 when the mount 14 is positioned in the lowered position. Additionally, the wheels 58 support the weight of the trailer 12 when the mount 14 is positioned in the lowered position. The support surface 62 may be ground.
A motor 64 is coupled to the wheel shaft 50. The motor 64 may be an electrical motor of any conventional design. A gear box 66 is mechanically coupled to the motor 64. The motor 64 drives the gear box 66. The gear box 66 may be a gear reduction box of any conventional design. Additionally, the gear box 66 increases a torque of the motor 64. A chain 67 is coupled between the gear box 66 and the wheels 58. The gear box 66 rotates the wheels 58 when the motor 64 drives the gear box 66.
A second actuator 68 is coupled between a front side 70 of the perimeter edge 16 of the mount 14 and the wheel shaft 50. The second actuator 68 may rotate the wheel shaft 50 in a first direction and a second direction. Additionally, the wheels 58 are positioned at a selected angle with respect to the mount 14 so the trailer 12 may be steered. The second actuator 68 may be an electrical actuator of any conventional design.
A control 72 is provided. The control 72 may be held by a user. A cord 78 is coupled to and extends outwardly from the control 72. A power supply 74 is provided. The power supply 74 is coupled to the trailer 12. The cord 78 is electrically coupled to the power supply 74. The power supply 74 is electrically coupled to the first actuator 44, the second actuator 68 and the motor 64. The power supply 74 actuates and de-actuates each of the first 44 and second 68 actuators and the motor 64. The power supply 74 comprises at least one battery 76.
In use, the mount 14 is positioned in the lowered position when the trailer 12 is to be manually moved along the support surface 62. The motor 64 is selectively actuated to urge the trailer 12 along the support surface 62. The second actuator 68 is selectively actuated to steer the trailer 12 while wheels 58 urge the trailer 12 along the support surface 62.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and 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 an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
