BACKGROUND OF THE INVENTION
1. Field of the Invention
The apparatus of the present invention relates generally to spare tire carriers for use with trucks. More particularly, the present invention relates to a spare tire frame that attaches underneath trucks, such as for example utility trucks or G-series trucks.
2. General Background of the Invention
Spare tires are typically carried on a truck bed, rear frame, or below the tailgate of a truck. When cargo is carried in a truck, there is often no room for a spare tire. Also, for trucks such a G-series trucks, a spare tire carrier cannot be secured under the tailgate of the truck. Spare tires are often removed from a truck if there is no room for it, leaving a driver and his cargo on the side of the road with a flat tire and no spare tire to fix it. It is desirable to carry a spare tire underneath a truck so that there is more space in the truck and it is easily accessible if needed.
It is also desirable to securely fasten a spare tire to a truck to prevent theft of the tire and to stop/prevent the tire from falling off of the truck during transit. In the past, tires have been secured using a rope, cable, lock bar, and/or padlock. These securing mechanisms are not protected and can easily be cut and removed, allowing the tire to be stolen.

The vertical section 32 can be connected to the truck frame 41 to hold the frame 10 to the truck 40 with bolts 44 that are placed through holes 46. Arms 11 are attached to the horizontal section 33. The arms 11 can be connected to the horizontal section 33 with bolts 44 through holes 47.
The apparatus of the present invention includes a locking mechanism to hold the tire 18 to the frame 10. The locking mechanism includes a swing arm 15, an adjustment leg 20 and a pole 19. Swing arm 15 is connected to vertical section 32 of frame plate 14. Swing arm 15 can be a round bar that is molded into an L shape. The lower end 34 of swing arm 15 is connected to vertical section 32 by a pipe with teflon or plastic bearing/bushing 22. A flat washer 25 can be attached, such as tack weld, above the teflon bearing 22 to prevent vertical movement of the swing arm 15. A flat washer 25 can be attached below the teflon bearing 22 to prevent vertical movement of the swing arm 15. The pipe 22 with teflon or plastic bearing can be about 3 inches long and about 5⁄8 inches wide. The lower end 34 of swing arm 15 can be connected to horizontal part 33 of frame plate 14 by a wheel lock nut 36 with a lug bolt. Optionally, the lower end 34 of swing arm 15 ends at the connection to bearing 22, as seen in FIG. 11. Preferably, a Ford keyed lug nut is used to allow a user to remove an existing swing arm and replace it with a new swing arm 15. Swing arm 15 can be about 3⁄8′′ thick. The lower end 34 of swing arm can be 7 inches long and the upper end 35 can be 17 inches long. A conduit pipe 13 is attached to the end of swing arm 15 (see FIGS. 5, 10). Conduit pipe 13 can be attached by welding to the swing arm 15. The conduit pipe 13 can be 2′′ thick. The conduit pipe 13 has a hole 17 on the front of the pipe 13 to allow for a lock pin 16 to be inserted into pipe 13.
Pole 19 can be attached in between the arms 11 as seen in FIG. 5. Adjustment leg 20 is attached to pole 19 and located near the center of the frame 10. The adjustment leg 20 can have a hole in which the round bar 19 can be fit through to hold adjustment leg 20 to arms 11 of frame 10. Adjustment bar 20 can rotate on pole 19 from a resting position (see FIG. 1) to an upright position (see FIG. 5).
In one an alternate embodiment (not shown in figures), a small round bar 38 can be connected to the top of adjustment leg 20 and has a hole 39 at the top of the small bar 38 for a lock 115 to fit through. The hole 39 can be 5/16 inch thick. The round bar 38 can be 3⁄4 inch thick and 4 inches long, with 3⁄4 inch of the bar 38 extending out of adjustment leg 20. The adjustment leg 20 and bar 38 can extend 151⁄2 inches above pole 19. Adjustment leg 20 can be 11⁄2 inches thick.

Optionally, a cover box 24 can be attached to adjustment leg 20 and used to securely cover the conduit pipe 13 and locking mechanism. It is buyer's choice if he wants to cover the lock or not. The locking mechanism can be accessed by lifting the cover box 24. When the cover box 24 is in a closed position (see FIG. 7) it fully conceals the lock pin 16. Swing arm 15 has a stop 37 that prevents the cover box 24 from damaging the swing arm 15 when the cover box 24 is lifted and released. Cover box 24 is attached to adjustment bar 20 with a sleeve 26 and pin 29 that act as a hinge on which the cover box 24 swings from a closed position to a lifted position (see FIG. 9). Cover box 24 can have a round bar 42 attached along the bottom edge to prevent a user from cutting his hand during use.
Cone 21 can be attached to the top of adjustment leg 20 by screwing cone 21 on a threaded section 23 of adjustment leg 20. The cone 21 can have a diameter of 8 inches, and a height of 8 inches. The top of the cone 21 has a round bar 43 attached to it so that there is no sharp edge at the top of cone 21. The round bar 43 prevents a user from cutting their hand on a sharp edge of cone 21. The round bar 43 can be 1⁄4′′ thick. The cone 21 is screwed down on the adjustment leg 20 so that it fits in the hub of a tire 18 and is in a position that can lock the wheel 18 onto the frame 10.
Frame plate 14 can be attach to the underside of truck frame/beams 41 in order to hold the apparatus 10 to the vehicle 40. The frame 10 can also be attached to the truck frame/beams 41 with braces 28. Braces 28 attach to flat bar 12 and are preferably L-shaped, having a vertical portion 48 and a horizontal portion 49. The vertical portion 48 can have holes 50 for attaching to truck frame 41 with clamps 45 or bolts 44.

Preferably a brace 28 can be attached on each side of the frame 10 (see FIGS. 5-7), and attached to flat bar 12 at the connection intersection 30 of flat bar 12 to arm 11. Brace 28 slides underneath flat bar 12 to hold the flat bar 12 to the truck frame 41. The braces 28 can be 2 inches wide, the brace vertical section can be 161⁄2 inches long, and the brace horizontal section can be 77⁄8 inches long.
The braces 28 can be secured to the truck frame 41 with clamps 45 that attach the braces 28 to the truck bed frame 41, securing the tire frame 10 to the vehicle 40. Different type of clamps 45 are required for different types of truck frames, such as truck frames with L-shaped beams, truck frame with I-shaped beams, and truck frames with square tubing beams. FIGS. 6-8 show some of the different clamps 45 that can be used with the apparatus of the present invention.
The dimensions of the present invention can be larger or smaller depending on the size of the tire to be stored. For example, a support frame for a 28′′ tire can have holes 47 that are about 1⁄2′′, the bolts 44 can be about 11⁄4′′ long with lock nuts (not shown). In this embodiment, the horizontal section 33 of frame plate 14 is shorter (about 2′′ instead of about 3′′). A tire support 10 for a larger tire 18, such as a 32′′ tire would preferably have a longer horizontal section 33 of frame plate 14 for the bigger tire 18.
In an alternate embodiment, a flat washer 119 (about 1⁄8′′×3⁄4′′) can be used with the swing arm 15 to prevent movement of the swing arm 15. In another embodiment, a frame/backing plate 14 has holes 46 that are oblong vertical, about 13/32′′× 13/16′′. All holes 46, 47 can be made oblong, about 13/32′′× 13/16′′, on horizontal section 33 of the frame/backing plate 14.
In another embodiment, the braces 28 have holes 51 that are oblong-shaped holes (about 13/32′′× 13/16′′) on the horizontal portion 49 of braces 28. The holes 50 on the vertical portion 48 of braces 28 are still about 3⁄8′′.
In another embodiment, arms 11 can have holes 55 that are oblong-shaped about 13/32′′× 13/16′′. The swing arm 15 can optionally have a lock box 24. A washer 119 can be placed at the top and bottom of the swing arm 15 that is attached to the frame/backing plate 14 as seen in FIG. 4. The washers 119 can be about 1⁄8′′ thick×about 3⁄4′′ hole×about 11⁄2′′ width, and welded in place to secure swing arm 15 in place. The washer 119 can be welded to the tire frame 10.
In another embodiment (not shown), a lock box 24 sized to about 3′′, a nipple (about 3⁄4′′) can be added for spacer and to keep the swing arm 15 (about 3⁄4′′) in place to swivel in and out. A round bar stock (about 1⁄4′′) can go through the lock box 107 and attached to the outside of the box. A spacer round bar (about 3⁄4′′) with a hole (about 1⁄4′′) can be made in the middle of the box for the swing arm 15.
In another embodiment, a flat backing plate 14 can be 71⁄2′′ long and all the holes 46, 47 can be oblong, about 13/32′′× 13/16′′.
Instructions for Assembly:


    (1) Find four WI beams (can also be L beams or C channels, depending on type of truck frame) on underside of truck frame 41.
    (2) In the center of the middle two beams, place backing plate 14 on frame of truck 41. You may have to pre-drill holes for attachment to the truck frame 41.
    (3) Attach braces 28 (loosely attached bolts 44 on clamps 45 on the two center beams of the truck frame 41). Optionally, backing plate 14 can be welded for permanent connection to truck frame (no clamps needed).
    (4) Attach flat bar 12 in between braces 28.
    (5) Attach arms 11 on top of flat bar 122, and on braces 28 and plate 14.
    (6) Install threaded T-bar 20 on pole 19 between arms 11.
    (7) Install swing arm 15 on plate 14, and on other side of threaded T-bar 20 for final connection.
    (8) Tighten all bolts 44—using aviation lock nuts/bolts included in package (not shown).
    (9) Put tire 18 on vertical portion of threaded T-bar 20.
    (10) Place cone 21 on vertical portion of threaded T-bar 20, and screw cone 21 down threaded T-bar 20 until tight against the tire 18 (cone 21 is snugly secured in rim of tire 18).
    (11) Tire 18 is now sitting on top of threaded T-bar 20, arms 11 and flat bar 12 (see FIG. 6).
    (12) Swing arm 15 (with or without lock box) is then connected to threaded T-bar 20.
    (13) Swing arm 15 can be lifted off of threaded T-bar 20 and swing away so that the user can unscrew cone 21 to remove tire 18.
    (14) When swing arm 15 is in place on threaded T-bar 20, a slide pad lock 115 is inserted into holes in swing arm 15 and T-bar 120 to lock tire 18 in place on tire frame 10.
    (15) Swing arm 15 has the option of a lock box 24 to further secure and lock tire 18.


Clamps 45 are truck-specific. Swing arm 15 can be already connected to plate 14 in package as sold. After everything is tightened down, a hole can be drilled into the clamp 45 of about 7/16′′ in H beam to secure the tire frame 10 to the truck frame 41. Securing the swing arm 15 keeps it from sliding and damaging truck frame 41. Braces 28 need separate holes to secure to body of the truck 40. Clamp gaps can be a little bigger for different size frames. A hole (not shown) is preferably added in the side of cone 21 to allow water, road grime, etc to escape and not get trapped in cone 21 and threads 23.
