Lift detection and alert assembly

Abstract

A lift detection and alert assembly for detecting lifting of a tow vehicle and for alerting a crane operator includes an alert module and a sensing module, which are mountable to a tow vehicle having a load engaged thereto. The alert module provides notification to an operator of a crane that is engaged to and operable upon the load. The sensing module detects vertical movement of the tow vehicle and signals the alert module thereof. The alert module notifies the operator of the crane in event the tow vehicle is being lifted in conjunction with the load to prevent damage to the tow vehicle and injury to a driver thereof. The present invention is anticipated for use with terminal tractors that are utilized to move shipping containers at cargo yards, warehouse facilities, and intermodal facilities.

Description

BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWING(S)

(1) 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:

(2) FIG. 1 is an in-use view of a lift detection and alert assembly according to an embodiment of the disclosure.

(3) FIG. 2 is a top view of an embodiment of the disclosure.

(4) FIG. 3 is a block diagram of an embodiment of the disclosure.

DETAILED DESCRIPTION OF THE INVENTION

(5) With reference now to the drawings, and in particular to FIGS. 1 through 3 thereof, a new alert assembly embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

(6) As best illustrated in FIGS. 1 through 3, the lift detection and alert assembly 10 generally comprises an alert module 12 and a sensing module 14, which are configured to be mountable to a tow vehicle having a load engaged thereto. The alert module 12 and the sensing module 14 can be mounted to the vehicle utilizing mounting means such as, but not limited to, magnetic couplers, brackets, adhesives, and the like.

(7) The alert module 12 is configured to provide notification to an operator of a crane that is engaged to and operable upon the load. The sensing module 14 is configured to detect vertical movement of the tow vehicle and to signal the alert module 12 thereof. The alert module 12 is configured to notify the operator of the crane in event the tow vehicle is being lifted in conjunction with the load to prevent damage to the tow vehicle and injury to a driver thereof. The present invention is anticipated for use with terminal tractors that are utilized to move shipping containers at cargo yards, warehouse facilities, intermodal facilities, and the like.

(8) As shown in FIG. 2, the alert module 12 is configured to be mountable to a roof of a cab of the tow vehicle. The alert module 12 comprises at least one of a horn 16 and a bulb 18, which should be interpreted to mean only one or more horns 16, only one or more bulbs 18, or any combination thereof. The horn 16 and the bulb 18 are configured to provide an audible alert and a visual alert, respectively, to the operator of the crane, and to other persons proximate to the tow vehicle. The present invention also anticipates the alert module 12 comprising other alerting means, such as, but not limited to, visual alerting means and audio alerting means within a cab of the crane.

(9) The horn 16 may be one of a plurality of horns 16. The plurality of horns 16 may comprise two horns 16, as shown in FIG. 2. The bulb 18 is configured for intermittent illumination. The bulb 18 may comprise a beacon light 20. The beacon light 20 may comprise a plurality of light emitting diodes 22, or other lighting means known to those skilled in the art of signal lights, such as, but not limited to, incandescent bulbs, halogen lamps, fluorescent lamps, and the like.

(10) The sensing module 14 may comprise a set of altimeters 24. The set of altimeters 24 may comprise two altimeters 24, which are configured to be mountable to opposed sides of the tow vehicle, as shown in FIG. 2. The sensing module 14 also may comprise other sensing means to detect lifting of the tow vehicle, such as, but not limited to, proximity sensors, distance sensors, and the like.

(11) The assembly 10 also comprises a microprocessor 26, which is configured to be operationally engaged to an electrical circuit of the tow vehicle. The microprocessor 26 is operationally engaged to the alert module 12 and the sensing module 14 and thus is positioned to selectively actuate the alert module 12 upon detection of vertical movement of the tow vehicle by the sensing module 14.

(12) In use, the sensing module 14 and the alert module 12 are affixed to the tow vehicle. Should the sensing module 14 detect lifting of the tow vehicle while the load is being lifted from the tow vehicle, it will signal the alert module 12. The alert module 12 will activate so that the horn 16 and the bulb 18 notify the crane operator of the lifting of the tow vehicle. This allows the crane operator to terminate lifting and to lower the tow vehicle.

(13) 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.

(14) 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. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be only one of the elements.
