The detailed description set forth below references the following drawings:
The present disclosure, as demonstrated by the exemplary embodiments described below, can propel vehicles such as a skateboard or snowboard or sled. One or more embodiments of the present disclosure can be used to push or pull a children's wagon or carriage. One or more embodiments of the present disclosure can also be used to assist moving a dolly up an incline or down a hall way. One or more embodiments of the present disclosure can power a manual wheel chair. One or more embodiments of the present disclosure can make a workload easier in situations where moving a heavy wheeled object may be problematic, such as if one were working alone in construction and needed to dolly around tools around a school or other large facility.
One or more embodiments of the present disclosure can solve various problems. A first can be that electric skate boards are expensive one or more embodiments of the present disclosure can be cheaper and available in different price amounts depending on use. One or more embodiments of the present disclosure can also makes snowboarding much easier to learn and can allow one to avoid the lines at the resort and tow oneself back up the hill. This may save money on lift tickets as well. Electric skateboards are also very fragile. They seem to break very easily and can't be used to perform tricks or race when broken, making them strictly for transportation. One or more embodiments of the present disclosure can allow the rider to lift the wheel for big bumps or threats to the motor. One or more embodiments of the present disclosure can also allow the rider to resume use as a normal skateboard/snowboard with the push of a button. This also gives the operator a great chance to get some good hands-free video footage of themselves. One or more embodiments of the present disclosure can be used for transportation as well. One or more embodiments of the present disclosure can appeal to a lot of people, not just skateboarders and snowboarders but to a vast variety of people.
One or more embodiments of the present disclosure can give controlled functional mobility to wheeled objects. One or more embodiments of the present disclosure can function with one to three interchangeable batteries powering an electric motor attached to a drivable member such as wheel or winter track. A clamp can be above the drivable member that can be clamped to objects (mechanical, hydraulic and electric clamp versions), all with quick release on the handle. A frame can extend to a handle supporting controls. The handle may be able to pivot and lock depending on what leverage is needed or can also be adjust to accommodate the height of the user or the amount of pressure applied to the ground or floor with the wheel.
The handle can support multiple control buttons, such as an acceleration button, a braking button, a clamp release, and a tripod release. Tripod legs can be maintained in a refracted position so the user can skate board, for example, and can be released as the user and skateboard separate from the embodiment so that the embodiment will not be damaged. When a camera is mounted on the embodiment, such as a phone that has a camera, the embodiment can thus act like a camera tripod capturing a great picture. The legs also add stability to an embodiment if needed by a particular user. The product disassembles very quickly and can be stored in a backpack or bag leaving ample room for the rest of the operator's belongings. The backpack can include a special holder for a skateboard, while leaving a large amount of extra space to pack other belongings and done so with maximum organization. One or more embodiments of the present disclosure can include a motor lock requiring a key to start the motor for security. One or more embodiments of the present disclosure can include a delayed brake timer for the best camera quality. The brake trigger can lock or the brake itself can lock if triggered.

A propulsion device 10 according to an exemplary embodiment of the present disclosure is shown in
The frame 14 can extend from a base or lower end 20 to an upper end 22. A handle 24 can be mounted at the upper end 22. The handle 24 can support a plurality of user-engagable buttons or levers.
A motor 26 can be mounted on the frame 14. The exemplary motor 26 can be an electric motor powered by one or more batteries. The batteries can be stored in the hollow members 16, 116 of the frame 14. In other embodiments, the motor 26 can be a gas-powered engine. In other embodiments, a drill could be used as the motor. Controls for the motor 26 can be mounted on the handle 24. A first button 28 can cause the motor 26 to accelerate. A second button 30 can cause the motor 26 to decelerate, such as by engaging a brake (not shown).
A drivable member 32 can be mounted on the frame 14. The drivable member 32 can be driven in motion by the motor 26. The exemplary drivable member 32 is a wheel.
A plurality of legs 34, 134 can each be mounted on the frame 14 for pivoting movement between a respective retracted position and a respective extended position.
A lock can be disposed to selectively lock the plurality of legs 34, 134 in the respective retracted positions. Referring to
The lock 42 can also include a wire 54 engaged at a first end to the latch 44 and at a second end to a button 56 mounted in the handle 24. The button 56 can be pivotal about a pin 58. When the user urges the button in the direction referenced by arrow 60, the latch 44 rotates about the pin 46 and the hook portion 50 separates from the hook portion 52.

In operation, a user can be riding the skateboard 12 while holding the handle 24. The legs 34, 134 can be locked in the respective retracted positions. The user can be pressing the first button 28, causing the motor 26 to drive the drivable member 32 and propelling the user and skateboard 12 forward. The user can have mounted a camera in the mounting member 74 and activated the camera so that the camera is filming.
At a moment chosen by the user, the user can cease pressing the button 28 and press the button 56 to release the lock 42 retaining the legs 34, 134. The biasing devices, such as biasing device 36, can urge the legs 34, 134 into the respective extended positions. The legs 34, 134, frame 14, and mounting member 74 can thus cooperate to define a tripod supporting the camera.
At a moment chosen by the user, the user can cease pressing the button 28 and press the button 56 to release the lock 42 retaining the legs 34, 134. The biasing devices, such as biasing device 36, can urge the legs 34, 134 into the respective extended positions. The legs 34, 134, frame 14, and mounting member 74 can thus cooperate to define a tripod supporting the camera. Generally at the same time, the user can press the button 70 thereby releasing the clamp 62. This uncouples the device 10 and the skateboard 12.
The user can then release the handle 24 and execute a skateboard move while the camera films the move from close proximity. By way of example and not limitation, the user can complete a backside, catch air, or perform a kick-flip as the camera is supported on the device 10 and filming.
Referring now to
The primary body 78 can be flexible, such as formed from fabric. The secondary body 80 can be rigid, such a plastic box-like structure. The secondary body 80 can have an opening 88 surrounded by the outer surface 82. The opening 88 can be substantially flush with the outer surface 82. The primary body 78 and the secondary body 80 can be connected in any desired way, including thermal welding, adhesive, or fasteners.
The secondary body 80 can be at least partially positioned within the primary cavity and can define a secondary cavity 90. A plurality of doors 92, 192 can extend across a majority of the opening 88. Each of the plurality of doors 92, 192 can be pivotable between a respective open position and a respective closed position.
A gap can be defined between the plurality of doors 92, 192 when each of the plurality of doors 92, 192 is in the respective closed position.
The secondary cavity 90 can include a first portion 96 and a second portion 196 shaped substantially similarly and spaced from one another. The secondary cavity 90 includes a third portion 296 shaped differently from and positioned between the first portion 96 and the second portion 196. In operation, the user can open the doors 92, 192. The user can then direct the wheels of the skateboard 12 into the first portion 96 and the second portion 196 and direct a truck of the skateboard 12 into the third portion 296. The doors 92, 192 can swing closed as the wheels and truck of the skateboard are being received in the secondary cavity 90. The diamond-shaped gap can surround a portion of the truck of the skateboard. The biasing devices 94, 194, 294, 394 can keep the doors 92, 192 closed and thereby keep the skateboard 12 mounted on the backpack 76.
Alternatively, an embodiment of the present disclosure can have doors that slide rather than pivot. A pair of such doors can be arranged with gears to move rectilinearly at the same time, either closer together or further apart. Such doors can be smaller and vertically-oriented versions of horizontally-oriented hanger doors. Such doors could cooperatively define a gap or aperture when closed to fit around a portion of the truck of the skateboard 12. Such doors could be biased to the closed position by one or more springs.
It is noted that the secondary body 80 and any associated doors can be an aftermarket item. The secondary body 80 could be added to retrofit an already-purchased backpack. The backpack can be modified by cutting an appropriately-sized and—shaped hole in the backpack. The installation can be guided by a template/faceplate for proper installation.
In one or more embodiments, the device 10 can include a system to move the camera. The camera can be moved to follow the user after the user has released the device 10. The camera could be moved from side to side and up or down. The system can include a sensor and/or transmitter worn by the user, a receiver on the device 10, and a processor configured to detect the position sensor based on the signals received by the receiver.
