BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of brush guards in general, and in particular to a spring loaded brush guard that is actuated by impact with the body of an animal.
2. Description of Related Art
As can be seen by reference to the following U.S. Pat. Nos. 1,293,224; 4,213,645; 4,469,360; 4,570,367; 6,682,111 and 6,676,180, the prior art is replete with myriad and diverse brush guards, cow catchers, and other arrangements designed to protect the front of a moving vehicle.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical device that employs stored energy to propel an animal away from the path of a moving vehicle to minimize potential damage to the vehicle proper and/or its occupants.
Recently, many suburban areas have been experiencing a rash of deer/vehicle collisions involving both extensive damage to the vehicle bodies as well as injuries that are sometimes fatal to the occupants of the vehicle.
As a consequence of the foregoing situation, there has existed a longstanding need among motorists for a new and improved type of brush guard that is capable of propelling a deer or other large animal out of the path of a moving vehicle using stored energy, and the provision of such an arrangement is a stated objective of the present invention.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the present invention provides an impact actuated animal deflector system that forms the basis of the present invention comprises in general a deflector unit, a stored energy unit, and a release unit that maintains the deflector unit in a retracted position whereupon a physical impact of a certain magnitude will cause the release unit to be disengaged from the stored energy unit which will propel the deflector unit in the direction of travel of the moving vehicle.
As will be explained in greater detail further on in the specification, the deflector unit comprises in general a reinforced brush guard member which is movably disposed relative to the front of a vehicle chassis.
In addition, the stored energy unit comprises a compressed spring member that is interposed between the brush guard member and the vehicle chassis, wherein the compressed spring member is pre-loaded by external forces and normally held in place by the release unit.
Furthermore, the release unit comprises a pivoted release member that is normally spring biased into the “release” position but which is overcome by the force of the compressed spring member until such time as an impact of a certain magnitude will further compress the compressed spring member to allow the spring biased release member to be disengaged from the brush guard member allowing the brush guard member to be propelled forwardly in the direction of travel of the vehicle chassis.



BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
These and other attributes of the invention will become more clear upon a thorough study of the following description of the best mode for carrying out the invention, particularly when reviewed in conjunction with the drawings, wherein:
FIG. 1 is a perspective view of the animal deflector system at rest;
FIG. 2 is a perspective view of the deflector system immediately prior to impact with an animal;
FIG. 3 is a perspective view of the deflector system a fraction of a second after impact;
FIG. 4 is a cross-sectional view showing the structural units in their pre-loaded orientation; and
FIG. 5 is a cross-sectional view showing the structural units in their immediate post-impact orientation.



DETAILED DESCRIPTION OF THE INVENTION
As can be seen by reference to the drawings, and in particularly to FIG. 3, the impact actuated animal deflector system that forms the basis of the present invention is designated generally by the reference number (10). The deflector system (10) comprises in general a deflector unit (11), a stored energy unit (12) and a release unit (13). These units will now be described in seriatim fashion.
As can best be appreciated by reference to FIGS. 3 and 5, the deflector unit (11) comprises a brush guard member (20) having a pair of vertical braces (21) that support rigid framework (22) having a plurality of horizontal support rods (23) that define an outer grillwork that is disposed above the front bumper (101) of a vehicle.
In addition, the brush guard member (20) is further provided with a reinforced cross-brace (25) that extends between the pair of vertical braces (21), wherein the cross-brace (25) forms a bearing surface for the stored energy unit (12), and a point of engagement for the release unit (13) as will be explained presently.
Turning now to FIGS. 3 through 5, it can be seen that the stored energy unit (12) comprises a pair of compression spring members (30) each having one end mounted on one of a pair of bearing plates (31) each fixedly secured to the front of the vehicle framework, wherein the other end of each compression spring (30) is fixedly secured to one of the vertical braces (21) of the brush guard member (20).
As can also be seen by reference to FIGS. 3 through 5, the release unit (13) comprises a pair of release lever members (40) each having one end pivotally secured to one of the bearing plates (31) wherein the free end of each lower member (40) has a hooked portion (41) that releasably engages a portion of the cross brace (25) of the brush guard member (20).
In addition, the release unit (13) further includes a pair of tension springs (42) each having one end attached to one of the bearing plates (31), wherein the other end of each of the tension springs (42) is attached proximate to the free end of one of the lever members (40).
Furthermore, as can best be seen by reference to FIG. 5, the compression springs (30) are substantially stronger than the tension springs (42) and the reason for that different will be explained next.
As shown in FIGS. 1 through 3, the deer deflector system (10) of this invention must first be pre-loaded once it is installed on the front of a vehicle (100), such that the compression spring (30) is substantially but not fully compressed when the hooked portion (41) of the lever arm (40) is engaged with the cross brace (25) to place the brush guard member (20) in its “cocked and loaded” disposition. It is to be understood that this “pre-loading” is accomplished by an authorized mechanic or the like.
When the brush guard member (20) experiences a forceful impact, such as would be generated by the moving vehicle (100) striking a deer (200), the compression springs (30) will be momentarily fully compressed allowing the tension springs (42) to disengage the hooked portions (41) of the lever arms (40) from the cross brace (25), whereupon the compression springs (30) will propel the brush guard member (20) against the deer (200) out of the path of the moving vehicle (100).
Although only an exemplary embodiment of the invention has been described in detail above, those skilled in the art will readily appreciate that many modifications are possible without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the following claims.
In the claims, means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents, but also equivalent structures. Thus, although a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooded parts together, whereas, a screw employs a helical surface, in the environment of fastening wooden parts, a nail and a screw may be equivalent structures.
Having hereby described the subject matter of the present invention, it should be apparent that many substitutions, modifications and variations of the invention are possible in light of the above teachings. It is therefore to be understood that the invention as taught and described herein is only to be limited to the extent of the breadth and scope of the appended claims.
