The present application claims priority to United Kingdom Patent Application serial number GB1816331.1, filed on Oct. 6, 2018, the disclosure of which is hereby incorporated in its entirety at least by reference.
The present invention generally relates to dispensing system but more particularly to an integrated abrasive material dispensing system for a wheeled vehicle.
Every year, for nearly five consecutive months in certain countries, road conditions are difficult because of ice and snow. Due to the difficult road conditions, accidents are increased by 30%. Even with the best winter tires, good traction may not be guaranteed. Anti-lock braking systems (ABS) are an extremely useful invention that improves handling when locking wheels. However, this system alone is not optimal for helping braking on slippery roads. Thus, in general these roads are cleared from snow and abrasive materials are laid on roads to prevent and remove snow and ice. However, it takes time to do the clearing and spreading abrasive materials on roads, especially smaller country roads which are processed after having done the highways and other main roads. Aside from using traction aids after a vehicle gets stuck or carrying a bag of abrasive in the trunk, which has limited use aside from spreading some abrasive materials in order to get going, there is not practical system that is always dependable to spread abrasive on demand.
The main problems caused by bad winter roads are the inability to brake within a reasonable distance and the loss of traction during acceleration. A vehicle's anti-skid system can help to a certain extent, but it can lead to smothering the engine to avoid a loss of control. This can be rather dangerous in some situations, such as when a driver want to make a turn on a busy road and the traction is not enough while the driver is in the middle of the street with a motor turning at low speed. Consequently, there is a need for an integrated abrasive material dispensing system for a wheeled vehicle.
The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.
In one aspect of the invention, an integrated abrasive material dispensing system for a wheeled vehicle is provided, comprising a hollow dispenser; a rotating brush roll having a plurality of flaps, wherein the rotating brush roll is positioned inside the hollow dispenser and is actuated via a motor; a dispensing pipe attached to a bottom portion of the hollow dispenser; and, a hopper configured to feed abrasive material into the hollow dispenser, wherein the rotating brush controls the flow of the abrasive material exiting the dispensing pipe.
In one embodiment, the rotating brush roll includes a cylinder and each of the plurality of flaps extend radially from the cylinder. In one embodiment, the plurality of flaps is four bristled flaps. In one embodiment, each flap of the plurality of flaps are configured to flex around clumps of abrasive material such that the rotation of rotating brush roll is not impeded. In one embodiment, the hollow dispenser has an inner perimeter surface and the distal portions of the plurality of flaps make contact with the inner perimeter surface such that a tight seal is formed preventing abrasive material from exiting the dispensing pipe when the rotating brush roll is not rotating.
In one embodiment, the integrated abrasive material dispensing system is configured to be attached to the vehicle's chassis. In one embodiment, a tank connected to the hopper is provided. In one embodiment, the tank is constructed from a flexible and insulating material to prevent condensation of the abrasive material.
In one embodiment, a control box configured to control the integrated abrasive material dispensing system is provided, wherein the control box is positioned inside the vehicle. In one embodiment, the control box includes an indicator light configured to alert a driver of the vehicle that a filling abrasive material is required. In one embodiment, the control box includes a motherboard having a timer, the motherboard in electrical communication with an ammeter clamp, wherein the ammeter clamp is installed around a motor wire of an ABS pump of the vehicle such that the ammeter clamp is configured to send a signal to the motherboard to detect if the ABS pump is functioning.
The foregoing has outlined rather broadly the more pertinent and important features of the present disclosure so that the detailed description of the invention that follows may be better understood and so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the disclosed specific methods and structures may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present disclosure. It should be realized by those skilled in the art that such equivalent structures do not depart from the spirit and scope of the invention as set forth in the appended claims.
Other features and advantages of the present invention will become apparent when the following detailed description is read in conjunction with the accompanying drawings, in which:
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein to specifically provide an integrated material abrasive dispensing system for a wheeled vehicle.
In one embodiment of the present invention, the system is configured to deploy abrasive material ahead of the front wheels of a vehicle when needed. The invention is activated manually or automatically depending on the situation. First, if the vehicle is stuck in a snowbank for example, the driver can operate the system via a push button in the front of a control box inside the vehicle. This greatly increases the chances of the driver to be able to get out of this situation without the intervention of a tow truck. Secondly, when the driver tries to brake, but the road conditions make it difficult, the system triggers automatically when the ABS is activated. The components and other features of the invention will be explained in greater detail below.

Advantageously, the brush roll 16 controls the flow of the abrasive material which dispenses through the dispensing pipe. One advantage of using bristle flaps 18 is that they can flex around potential clumps of abrasive material without jamming the rotational action of the rotating brush roll 16. Further, the bristle flaps provide a tight seal preventing any abrasive material from trickling down the dispensing pipe when the rotating brush roll 16 is not rotating. The tight seal is due to how the bristle flaps fit in the rotating bush roll 16, as the flaps make contact with the perimeter of the dispenser. In some embodiments, the rotating brush is guided by ball bearings (not shown) which reduces friction on the mechanical parts and ensures long life of the system in cold temperature environments.
In some embodiments, integrated abrasive material dispensing system 10 is bolted into the chassis of the vehicle via a bracket (not shown), preferably under the hood of the vehicle, for instance behind the front bumper, such that one system 10 is placed ahead of each of the two front wheels. In one embodiment, the tank is made from a flexible and insulating material to prevent condensation of the abrasive material. This avoids clumping in the tank and the hopper 12. To further prevent condensation, the bristled flaps 18 always close the system 10 from both the top and the bottom so as to prevent moist air from entering and clumping the abrasive material, which could block its flow and jam the dispenser.

In some embodiments, to detect an inability to brake, an ammeter clamp 26 is installed around one of the motor wires of an ABS pump 28. The ammeter clamp sends a signal to the motherboard 30 which turns on the timer 34 activates the system for approximately half a second. Thus, as long as the ABS pump 28 gives impulses, the countdown timer starts again.
