The present invention relates generally to the field of wheel chock systems. More specifically, the present invention relates to a wheel chock alert device that provides operators with a notification system for missing wheel chocks, thereby ensuring the chock is replaced, or returned to a stored position, before operating the vehicle. The wheel chock alert device features a visual indicator on one side of the device. The visual indicator is easily seen when the operator looks through a side view mirror (i.e. driver's side view mirror). The wheel chock alert device notifies an operator if a wheel chock is missing or is in use, and ensures the wheel chock is not left behind, lost and/or damaged. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices and methods of manufacture.
By way of background, use of wheel chock systems have been known in the state of the art. Wheel chocks (or chocks) are wedges of sturdy material such as polyurethane or rubber, that are placed closely against a vehicle's wheels to prevent accidental or incidental movement. The chocks can be placed in front of and/or behind tires to prevent unwanted movement of a vehicle. Chocks are typically used in conjunction with a vehicle braking system to secure the vehicle in a stationary position. For safety reasons, a vehicle prohibited from inadvertent movement provides a much safer environment to individuals working and walking adjacent to the vehicle. Wheel chocks are considered to be an effective safety device for vehicles if the chock devices are used properly.
When a vehicle is in an idle or parked condition and an operator desires to secure the vehicle in a stationary position, a wheel chock device is typically used for placement against one or more of the vehicle's wheel(s). A wheel chock can then be taken out from a storage area of the vehicle and positioned properly against the vehicle's wheel(s) to prevent any unwanted movement of the vehicle. Once the vehicle is ready for use again, the wheel chock device placed against the vehicle's wheel needs to be removed and placed into the storage area. However, operators or drivers often forget to remove the wheel chock that was previously placed against the vehicle's wheel. In situations where the wheel chock is placed in front or behind one or more of the vehicle's wheels and the operator forgets to remove the wheel chock, the result is inconvenience in further operating the vehicle and damages to the wheel chock as well. In case the wheel chock is placed behind the vehicle's rear wheel, and the operator forgets to remove the wheel chock, there is a potential of forgetting the wheel chock and leaving it behind at the jobsites and other areas. Replacing and purchasing wheel chocks can be costly and frustrating for operators and vehicle owners. Further, in situations where wheel chocks are not securely fastened to a vehicle, unsecured chocks can fly out onto the road when the vehicle is in motion. The resultant obstruction on the road presents a hazard for other motorists.
Currently, there are no means for vehicle drivers or operators to be alerted to the fact that the wheel chock is missing, still in use or unsecured before operating the vehicle. Operators may have to manually check the presence of the wheel chock in a vehicle's storage area prior to operating the vehicle. This manual activity is a time consuming and frustrating task for the operators.
Therefore, there exists a long felt need in the art for a wheel chock alert device that notifies operators of missing wheel chocks. There is also a long felt need in the art for a wheel chock alert device that eliminates the need to continuously manually check the presence of a wheel chock in a vehicle's storage area each time before operating the vehicle. Additionally, there is a long felt need in the art for a wheel chock alert device that ensures the wheel chock is returned to a storage position within the vehicle before operation resumes. Moreover, there is a long felt need in the art for a wheel chock alert device that prevents the wheel chock system from being damaged or lost in case the operator forgets to replace the wheel chock. Further, there is a long felt need in the art for a wheel chock alert device that prevents the wheel chock from being left behind or lost at jobsites and other locations. Furthermore, there is a long felt need in the art for a wheel chock alert device that prevents motorists and other vehicle operators from facing hazards due to unsecured wheel chocks landing onto the road or being left behind in parking lots. Finally, there is a long felt need in the art for a wheel chock alert device that provides a convenient missing wheel chock alert system, thereby preventing drivers from losing and/or leaving wheel chocks behind at jobsites and other locations.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a missing wheel chock alert device to notify an operator of a vehicle in the event that the wheel chock is missing from its storage position. The missing wheel chock alert device comprises: a retainer, bracket or docking unit dimensioned as per a wheel chock, an extension arm connecting and extending from the device, and a flag attached to the extension arm wherein the missing wheel chock alert device enables the flag to extend outward from the bracket so as to be visible to the operator via a side view mirror, indicating absence of the wheel chock. The missing wheel chock alert device, when the wheel chock has been returned to the bracket, causes the extension arm to be pushed back into the bracket such that the flag is not visible to the operator via the side view mirror, indicating secure placement of the wheel chock in the bracket.
In this manner, the novel wheel chock alert device of the present invention accomplishes all of the forgoing objectives, and provides a relatively easy, convenient and effective solution to provide notification to operators regarding missing wheel chocks, thereby ensuring the wheel chocks are not left behind at jobsites and other locations, and are returned before operating the vehicle. The wheel chock alert device of the present invention is also user friendly, as it eliminates the need to manually check if the wheel chock has been returned and stowed in the vehicle's storage area. The wheel chock alert device ensures the safety of wheel chocks and prevents unnecessary expense and hassles due to the inadvertent abandonment of wheel chocks.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some general concepts in a simplified form as a prelude to the more detailed description that is presented later.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a wheel chock alert device to notify an operator of a vehicle about a missing, misplaced or in use wheel chock. The wheel chock alert device comprises: a retainer, bracket or docking unit dimensioned as per a wheel chock; an extension arm connecting and extending from the device including a flag attached to the extension arm; the flag is deployed when the wheel chock is missing from the wheel chock retainer; and, wherein the deployed flag is visible to the operator via a side view mirror when the wheel chock is missing from the wheel chock retainer. When the wheel chock has been returned to the wheel chock retainer or bracket, the wheel chock extension arm is pushed back into the retainer or bracket once the wheel chock has been inserted into the bracket, such that the flag is unviewable to the operator via the side view mirror, indicating the secure placement of the wheel chock into the wheel chock bracket.
In a further embodiment of the present invention, a portable and lightweight flag device that is capable of alerting an operator of a missing wheel chock is disclosed and comprises: a solid retainer body having tapered sides forming a V-shape; one or more flags extending from the sides of the solid retainer body, wherein the flag device is configured to be inserted in a mounted bracket attached to a vehicle; the extended flag(s) can be visible to the operator via a side view mirror indicating the absence of the wheel chock in the bracket; and the retractable flag(s) being unviewable to the operator via the side view mirror, indicating the presence of the wheel chock in the retainer or bracket. The wheel chock device, when the wheel chock is inserted into the bracket, provides for retraction of the flag device, thereby moving the flags out of the view of the operator. It is to be appreciated that the operator can make a determination as to the status of the wheel chock while seated in the driver's seat of the vehicle
The missing wheel chock alert device of the present invention prevents operators from losing, misplacing or leaving behind wheel chocks at jobsites and other areas.

The present invention, in one exemplary embodiment, is a novel wheel chock alert device that provides notification to an operator of a vehicle regarding the status of wheel chocks. The wheel chock alert device comprises: a retainer, bracket or docking unit dimensioned as per a wheel chock; an extension arm extendable and retractable from the device; and a flag attached to the extension arm, wherein the flag is actuated when the wheel chock is removed from the mounted bracket of the wheel chock device; the flag, extending outward from the bracket, is viewable to the operator via the driver's side view mirror indicating absence of a wheel chock; and the extension arm of the wheel chock alert device is retractable when the wheel chock is returned to the bracket, such that the flag is unviewable to the operator via the driver's side view mirror indicating the secure placement of the wheel chock in the bracket.
Referring initially to the drawings,
As discussed above, the wheel chock alert device 100 can be shaped and dimensioned according to conventional wheel chock sizes and can include a bracket 101 comprising a frame 106 having a first tapered side 112 to which the extension arm 104 is attached. A second tapered side 110 connects to the first tapered side 112 along a bottom edge 108. A top edge 114 of the wheel chock alert device 100 forms the top side of the frame 106. The first tapered side 112 and the second tapered side 110 are similar in size and orientation. The wheel chock alert device 100 includes a relatively thin construction, providing for a compact and lightweight device made up of a sturdy material such as metal, rubber, HDPE (high density polyethylene) or other durable and impact resistant materials.
The frame 106 of the wheel chock alert device 100 can comprise a unitary construction. The wheel chock alert device 100 of the present invention can be constructed in any number of dimensions and sizes to fit and use with different types of wheel chocks. The extension arm 104 and the red flag 102 attached thereto, and articulated therewith, allow an operator to see the flag 102 from a distance. In one illustrative embodiment, the extension arm 104 can actuate a lateral distance, generally from about 6 inches to about 18 inches in length, from a retracted position to an extended position and vice versa. The wheel chock alert device 100 can come in multiple colors to match with the color of the vehicle.
When the missing wheel chock alert device 100 is inserted into the bracket 202, the tapered sides 112, 110 are placed along the corresponding tapered sides of the bracket 202. The bottom edge 108 of the alert device 100 abuts the bottom of the bracket 202. Due to the thin construction of the sides or walls 110, 112 of the alert device 100, the alert device 100 can be easily moved within the bracket 202 in a direction towards or away from the vehicle. In the scenario where only the alert device 100 is placed within the bracket 202, without any wheel chocks retained therein, the extension arm 104 remains extended outwardly away from the vehicle, thereby placing flag 102 in a viewable position relative to the driver's side view mirror 302 (
