Description
1. Field of the Invention
The present invention generally relates to a tailgate assembly and more particularly to a relatively strong and sturdy tailgate assembly which may be selectively and movably attached to a truck or other type of motor vehicle.
2. Background of the Invention
A tailgate assembly is usually and selectively attached to a truck or other type of motor vehicle having a storage bed or compartment. Particularly, the tailgate assembly is movable from a first closed position which allows materials or other items to be secured within the formed storage bed or compartment (i.e., the “closed” tailgate causes the formed storage bed or compartment to be selectively “closed”), to a second open position in which access is easily allowed to the storage bed or compartment (i.e., the “open” tailgate allows the formed storage bed or compartment to be selectively “opened”). While a conventional tailgate assembly does allow a formed storage bed or compartment to be selectively closed or opened, it does have some drawbacks.
By way of example and without limitation, a conventional tailgate assembly is typically susceptible to structural damage as it is impacted by items contained within the storage bed or as it is impacted by items or objects which reside outside of the formed storage bed, such as those items or objects which reside within the ambient environment through which the motor vehicle passes. Such damage is unaesthetically pleasing, undesirably requires costly repairs to be made to the vehicle by the owner of the vehicle, and, depending upon the severity of the impact, may also cause damage to occur to the items and materials which are contained in the formed storage bed or container e.g. the tailgate may be impacted in a manner which causes it to deformably contact some of the items which are stored in the formed compartment).
The present invention overcomes these drawbacks in a new and novel fashion.
It is a first non-limiting advantage of the present invention to provide a tailgate assembly which overcomes some or all of the previously delineated disadvantages of a conventional tailgate assembly.
It is a second non-limiting advantage of the present invention to provide a tailgate assembly including an inner panel; an outer panel; and at least one stiffening member which is operatively contained between the inner panel and the outer panel, the at least one stiffening member having a first flange portion which is coupled to the inner panel, a second flange portion which is coupled to the outer panel, and a broad face portion which is disposed between the first and second flange portions and which wholly resides within a single plane.
It is a third advantage of the present invention to provide a tailgate assembly comprising an outer panel which is symmetric about a certain plane of symmetry; an inner panel which is selectively coupled to the outer panel; and at least one stiffening member which is coupled to and which is operatively contained between the inner panel and the outer panel, the at least one stiffening members having a face portion which is perpendicular to the certain plane of symmetry.
It is a fourth advantage of the present invention to provide a tailgate assembly comprising an outer panel having an outer edge; an inner panel which is selectively coupled to the outer panel and which includes an outer edge; and a pair of substantially identical members which are coupled to the inner and outer panels, the pair of substantially identical members being linearly coextensive to both of the respective outer edges of the inner and outer panels and each of the pair of substantially identical members having a broad face portion which respectively forms a right angle with respect to each of the inner and outer panels, and each of the pair of substantially identical members having a pair of substantially identical flange portions which are respectively parallel to the outer edge of the inner panel and to the outer edge of the outer panel.
These and other features and advantages of the present invention will become apparent from a reading of the following detailed description of the preferred embodiment of the invention and by reference to the following drawings.
Referring now to FIG. 1 , there is shown a vehicle 10 having a tailgate assembly 12 which is made in accordance with the preferred embodiment of the invention. At the outset, it should be appreciated that the present invention is not limited to a certain vehicle type or configuration. Rather, the present invention may be used with a wide variety of dissimilar vehicles, including but not limited to the vehicle which is shown in FIG. 1 , and, as such, the present invention has a wide variety of applications.
As shown, the vehicle 10 includes a storage bed or compartment 14 and the tailgate assembly 12 is movably coupled to the vehicle 10 by the use of hinges (not shown) or by the use of other devices or mechanisms which allow the tailgate assembly 12 to be selectively moved from a first closed position (shown in phantom in FIG. 1 ) in which access to the formed storage compartment 14 is restricted, to a second open position (shown in FIG. 1 ) in which access is readily allowed to the formed storage compartment 14. While the tailgate assembly 12 selectively allows access to the formed storage compartment 14 in substantially the same manner as a conventional tailgate assembly, it is stronger and structurally sturdier than a conventional tailgate assembly, as is further discussed below.
As is best shown in FIGS. 2 , 3 and 4, the tailgate assembly 12 includes an inner panel 16, an outer panel 18, a cover panel 20, and a pair of substantially identical stiffening ribs or stiffening members 22, 24.
Particularly, as shown, the outer panel 18 has a body or broad face portion 30 with opposed outer edges 32, 34. Particularly, outer edge 32 is formed upon a curled or lip portion 33 which causes the edge 32 to reside above the body 30, while edge 34 resides within substantially the same plane as the body 30. The inner panel 16 is substantially the same size as the body or broad face portion 30 of the outer panel 18 and has a shape which generally conforms to the shape of the body portion 30 of the outer panel 18. Further, in one non-limiting embodiment, the inner panel 16 includes several substantially identical apertures 40. It should be appreciated that nothing in this description is meant to limit the present invention to the exact shape, size, or geometric configuration associated with the panels 16, 18 which are shown in FIG. 2. Rather, these panels 16, 18 may be of any desired shape or configuration.
The cover panel 20, in one non-limiting embodiment, comprises a generally rectangular member, and each of the stiffening ribs 22, 24 respectively comprise members having a generally “Z” shaped cross sectional area. Particularly, members 22, 24 each have a respective generally planar body or broad face portion 49, a respective first edge 50 which is formed on a respective flange portion 51 which forms a right angle with respective portion 49, and a respective second edge 52 which is formed on a respective flange portion 53 which also forms a right angle with respect to respective portion 49. Edges 51, 52 of each members 22, 24 are parallel to edges 32, 34. It should be appreciated that, in one non-limiting embodiment, cover panel 20 may be eliminated. In yet another non-limiting embodiment, the panels 16, 18 and members 22, 24 may cooperatively and integrally form portions of a single member or panel assembly.
In operation, the respective flange portion 53 of each of the stiffening members 22, 24 are each attached to the body portion 30 of the outer panel 18 such that the respective edges 52 are parallel to the edges 32, 34 of the outer panel 18. The respective flange portions 51, 53 of each of the stiffening members 22, 24 are each attached to the panel 16 and the panel 16 is attached to the outer panel 18, thereby causing the respective edges 50 to be parallel to edges 32, 34 of the inner panel 16. In this manner, each of the respective broad face portions 49 respectively and wholly lie within a single plane and are each respectively perpendicular to the plane of symmetry 19 which passes through the outer panel 18 and to the plane of symmetry 17 which passes through the inner panel 16. Each of the respective portions 51, 53 are also perpendicular to the planes of symmetry 17, 19. The inner panel 16 is then attached to the outer panel 18 (by a mechanical attachment assembly or by a bonding material), effective to cause the stiffening members 22, 24 to be operatively “sandwiched” between these panels 16, 18. Further, one, three, or more such stiffening members may be used in alternate embodiments of the invention and, in the most preferred embodiment of the invention, each of the operatively contained members 22, 24 are parallel to and are linearly coextensive to the edges 32, 34 (i.e., each of the respective portions 49, 51, 53 are parallel to and linearly coextensive to the edges 32, 34). Further, in the most preferred embodiment of the invention, the distance between member 24 and edge 32 is substantially similar to the distance between the member 22 and the edge 34. The cover panel 20 is then attached to the inner panel 16 in a manner in which the cover panel 20 overlays and hides the apertures 40. Further, in one non-limiting embodiment of the invention, the outer panel 18 includes an opening 37 and the inner panel 16 includes a tab 31 which resides within and which protrudes from the opening 37 when the panels 16, 18 are coupled, effective to allow a user to open and close the tailgate assembly 12 by the use of the protruding tab 31.
Particularly, the stiffening members 22, 24 structurally strengthen the tailgate assembly 12, thereby reducing the likelihood of deformation and degradation. In particular, the “Z”-shaped cross sectional area of these members 22, 24 in combination with the placement of these members in a manner which is perpendicular to the planes of symmetry 17, 19 allows these members 22, 24 to greatly strengthen the tailgate assembly 12, thereby making the tailgate assembly 12 resistant to damage. Moreover, the length of each of the members 22, 24 (i.e., the fact that they are linearly co-extensive to edges 32, 34) further increases the stiffness of the tailgate assembly 12. In one non-limiting embodiment, each of the members 22, 24, are made or created from steel or another relatively strong and rigid material and are respectively attached to the panels 16, 18 by glue or another conventional adhesive material, by a welded connection, or by any combination of conventional coupling techniques or methodologies. Alternatively, a strong and rigid composite material may be used to create members 22, 24. For example, in one non-limiting embodiment, flanges 51 are respectively welded to the panel 16 while flanges 53 are respectively bonded to the panel 18. Further, the panel 16 may be selectively attached to the panel 18 by glue or a conventional adhesive material, or by the use of conventional fastening members. Further, in one non-limiting embodiment, member 22 has a pair of substantially identical, opposed, and generally rectangular end flanges 78, which are selectively attached to panel 16 while member 24 has a pair of substantially identical, opposed, and generally rectangular end flanges 80 which are similarly and selectively attached to panel 16. Such attachment may be made by the use of a welded connection or by a bonding material. It should be appreciated that the end flanges 78, 80 further increase the stiffness of the formed tailgate assembly 12 by ensuring that members 22, 24 are “tightly coupled” to the panels 16, 18. These members 22, 24, when operatively contained between panels 16, 18, act to absorb and/or distribute and dissipate the various forces applied to the tailgate assembly 12, thereby reducing the likelihood of damage to the tailgate assembly 12.
It should be appreciated that the apertures 40 allow an assembler to determine whether the members 22, 24 are correctly and operatively placed between the panels 16, 18 before the coupled panels 16, 18 are placed upon the vehicle 10. After the determination is made, panel 20 “hides” these apertures 40 and may be attached to the panel 16 by glue or by an adhesive material. Further, in yet another non-limiting embodiment of the invention, members 22, 24 respectively comprise “I” beams and have a generally “I”-shaped cross sectional area.
It is understood that the invention is not limited to the exact construction and methodology which is disclosed above but that various constructions may be made without departing from the spirit and the scope of the invention as is delineated in the following claims.
