DETAILED DESCRIPTION OF THE INVENTION
With reference now to the drawings, and in particular to FIGS. 1 through 12 thereof, a new speed bump device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 12, the portable speed bump assembly 10 generally comprises a dolly 12 that has a spool 14 which is rotatably attached to the dolly 12 and the spool 14 is rotatable in a first direction or a second direction. The dolly 12 includes a push handle 16 and a pair of rollers 18 which can be rolled along a support surface 20 for transporting the dolly 12. The dolly 12 includes a frame 22 which comprises a pair of end members 24 each extending between and being perpendicularly oriented with a pair of outward members 26 such that the frame 22 defines a rectangular shape. The pair of end members 24 includes a front member 28 and a rear member 30 and the front member 28 has a front surface 32 which curves forwardly between a top edge 34 of the front member 28 and a bottom surface 36 of the front member 28. Additionally, the bottom surface 36 is spaced downwardly from a bottom surface 38 of each of the pair of outward members 26 and the front member 28 has a rear surface 40 which intersects the bottom surface 38 of each of the pair of outward members 26.
Each of the pair of rollers 18 is rotatably attached to an outwardly facing surface 42 of a respective one of the pair of outward members 26 at a point which is aligned with the rear member 30. Each of the pair of rollers 18 and the bottom surface 36 of the front member 28 rests on the support surface 20 while the dolly 12 is stationary. Conversely, the dolly 12 is tipped such that the bottom surface 36 of the front member 28 is lifted from the support surface 20 when the dolly 12 is being rolled along the support surface 20. The push handle 16 has a central member 44 extending between and being perpendicularly oriented with a pair of uprights 46. A cushion 47 is positioned around the central member 44 and the cushion 47 is comprised of a resiliently compressible material, including but not being limited to rubber or silicone, for enhancing comfort when gripping the central member 44.
A distal end 48 of each of the pair of uprights 46 is attached to a top surface 50 of a respective one of the pair of outward members 26 of the frame 22 at a point located adjacent to the rear member 30 of the frame 22. Each of the uprights 46 is oriented to angle rearwardly away from the frame 22 such that the central member 44 can be gripped for rolling the dolly 12. The frame 22 includes a support panel 52 extending upwardly from the top surface 50 of a respective one of the pair of outward members 26 of the frame 22. The support panel 52 has an upper end 54 which is rounded and a first lateral surface 56 and a second lateral surface 58.
A speed bump unit 60 provided and the speed bump unit 60 is rolled around the spool 14.

The roadway 62 may be a city road, a country road, a highway or any other type of paved public roadway. The speed bump unit 60 has an exposed surface 64 which is rounded such that the speed bump unit 60 defined a Quonset shape when the speed bump unit 60 is deployed. In this way the speed bump unit 60 can compel traffic 66 on the roadway 62 to slow down while driving over the speed bump unit 60 thereby reducing the average speed of the traffic 66. Additionally, the speed bump unit 60 is rolled around the spool 14 when the spool 14 is rotated in the first direction for storing the speed bump unit 60.
The speed bump unit 60 comprises a strip 68 which has a first end 70, a second end 72 and a top surface 74 extending between the first end 70 and the second end 72. The strip 68 is elongated between the first end 70 and the second end 72 to a length of at least 7.3 meters thereby facilitating the strip 68 to be extended across the full width of a typical two lane public roadway. The strip 68 has a hole 76 extending through the top surface 74 and a bottom surface 78 of the strip 68 and the hole 76 is located adjacent to the first end 70. Additionally, the strip 68 is comprised of a resilient and flexible material, including but not being limited to poly-para-phenylene terephthalamide or carbon fiber, such that the strip 68 can resist being damaged by repeated contact with the surface of the roadway 62.
The speed bump unit 60 includes a plurality of humps 80 which each has a front surface 82, a back surface 84, a bottom surface 86 and a top surface 88 and the bottom surface 86 of each of the plurality of humps 80 is attached to the top surface 74 of the strip 68.

The humps 80 are evenly spaced apart from each other and are distributed between the hole 76 and the second end 72 of the strip 68 having the front surface 82 and the back surface 84 of each of the plurality of humps 80 being spaced apart from an adjacent hump 80. The top surface 74 of each of the humps 80 curves upwardly from the bottom surface 86 of the humps 80 such that each of the plurality of humps 80 has a Quonset shape.
The speed bump unit 60 includes a plurality of reflectors 90 and each of the reflectors 90 is attached to the top surface 88 of a respective one of the plurality of humps 80. In this way each of the plurality of reflectors 90 is exposed when the strip 68 is rolled off of the spool 14 and positioned to extend across the roadway 62. Each of the plurality of reflectors 90 is comprised of a light reflecting material to reflect light from headlights of the traffic 66 thereby enhancing visibility of the plurality of humps 80 during darkened hours. The plurality of reflectors 90 includes a set of first reflectors 92 and a set of second reflectors 94. Each of the first reflectors 92 is aligned with a first lateral side 96 of the respective hump 80 and each the second reflectors 94 is aligned with a second lateral side 98 of the respective hump 80.
The spool 14 has a central hub 100 which extends between a pair of wheels 102 and the spool 14 has a shaft opening 104 which extends through each of the wheels 102 and the central hub 100. The shaft opening 104 has a bounding surface 106 and the bounding surface 106 has a keyway 108 extending between each of the pair of wheels 102. The spool 14 has a prominence 110 extending outwardly from an outside surface 112 of the central hub 100 and the prominence 110 is elongated to extend substantially between the pair of wheels 102. Furthermore, the prominence 110 extends through the hole 76 in the strip 68 when the strip 68 is initially attached to the spool 14 thereby facilitating the strip 68 to be wrapped around the central hub 100 when the spool 14 is rotated in the first direction.
A drive unit 114 is provided and the drive unit 114 is attached to the dolly 12. The drive unit 114 is in mechanical communication with the spool 14 for rotating the spool 14 in either the first direction or the second direction. The drive unit 114 comprises a motor 116 that is attached to the second lateral surface 58 of the support panel 52 at a point which is located closer to the upper end 54 of the support panel 52 than the frame 22.

Additionally, the drive shaft 118 has a key 124 which is disposed on the outer surface 120 and the key 124 extends from the first lateral surface 56 of the support panel 52 toward the distal end 122 of the drive shaft 118. The drive shaft 118 is rotated in either a first direction or a second direction depending upon the directional rotation of the motor 116. Additionally, the drive shaft 118 extends through the shaft opening 104 in the spool 14 having the key 124 extending through the keyway 108 in the bounding surface 106 of the shaft opening 104 thereby securing the spool 14 on the drive shaft 118.
The drive unit 114 includes a lock 126 that is movably integrated into the outer surface 120 of the drive shaft 118. The lock 126 is positioned between the key 124 and the distal end 122 of the drive shaft 118. The lock 126 is biased to extend away from the outer surface 120 and the lock 126 is urgeable to recess into the outer surface. The lock 126 may comprise a ball and a biasing member which biases the ball to extend outwardly from the outer surface 120 of the drive shaft 118. The drive unit 114 includes a cap 128 which is attachable to the distal end 122 of the drive shaft 118 when the drive shaft 118 is extended through the shaft opening 104 in the spool 14. The cap 128 abuts a respective one of the pair of wheels 102 of the spool 14 thereby retaining the spool 14 on the drive shaft 118. Additionally, the cap 128 has a hole 130 which insertably receives the lock 126 when the cap 128 is seated on the drive shaft 118 for securing the cap 128 to the drive shaft 118.
The drive unit 114 includes an extend button 132 that is movably integrated into the support panel 52 and the extend button 132 is electrically coupled to the motor 116. The motor 116 is actuated to rotate in the second direction when the extend button 132 is depressed. The drive unit 114 includes a retract button 134 that is movably integrated into the support panel 52 and the retract button 134 is electrically coupled to the motor 116. The motor 116 is actuated to rotate in the first direction when the retract button 134 is depressed.
The drive unit 114 includes a power supply 136 that is integrated into the support panel 52 and the power supply 136 is electrically coupled to the motor 116. The power supply 136 comprises a rechargeable battery 138 that is integrated into the support panel 52 and the rechargeable battery 138 is electrically coupled to the motor 116. The power supply 136 includes a charge port 140 which is recessed into the support panel 52 to insertably receive a charge cord 142. Additionally, the charge port 140 is electrically coupled to the rechargeable battery 138 for charging the rechargeable battery 138. The charge port 140 may comprise a micro universal serial bus port or other similar type of charge port. In an alternative embodiment 144 as is shown in FIG. 12, the drive unit 114 may comprise a hand crank 146 that is rotatably integrated into the support panel 52 for manually rotating the drive shaft 118.
In use, the spool 14 is slid onto the drive shaft 118 and the cap 128 is attached to the drive shaft 118 to retain the spool 14 on the drive shaft 118. The dolly 12 is transported to a location on a roadway 62 that requires a temporary speed bump for traffic control, such as road construction site for example. The extend button 132 is depressed to rotate the spool 14 in the first direction to unroll the speed bump unit 60 from the spool 14 thereby facilitating the speed bump unit 60 to be extended across the roadway 62. In this way traffic 66 on the roadway 62 is compelled to slow down to drive over the speed bump unit 60 thereby reducing the average speed of the traffic 66. The hole 76 in the strip 68 is aligned with the prominence 110 on the central hub 100 of the spool 14 and the retract button 134 is depressed to rotate the spool 14 in the second direction. In this way the speed bump unit 60 is wrapped around the spool 14 for subsequent transportation and storage. As is most clearly shown in FIG. 8, a plurality of the spools 14 is provided and a plurality of speed bump units 60 is each wrapped around a respective spool 14 to facilitate multiple speed bump units 60 to be deployed at various locations.
