The tongue 34 has a load receiving opening 35 located near the free end or tip 38 of the tongue 34, which along with the tip 38 of the tongue 34 serves as an attachment point. The load receiving opening 35 receives load securing straps 74 (FIG. 18) such as ratchet straps, load securing chains, bungee cords or other load securing flexible members. The load receiving opening 35 is generally rectangular shaped but with the corners rounded to resemble a racetrack. The upper end 73 of the load receiving opening 35 has a central retaining notch 40. The notch 40 has an upper end 76 (FIG. 13) and opposite right and left side ends 72 (FIG. 14) that extend downwardly and outwardly away from each other. The notch 40 receives a complimentary sized load hook (or alternatively securing strap or other load securing flexible member) to minimize right and left lateral movement of the load hook during the towing of the load by the vehicle. A pair of right and left anchor body mounting apertures 42R, 42L are formed in the tongue near respective right and left ends of the tongue. A pair of right and left vertical slits 44R, 44L are formed in the tongue and located below the anchor body mounting apertures 42R, 42L. The tongue 34 is integrally formed with the base 32 at the lower end of the tongue and freely extends upwardly from the base 32.
Each of the arms 36R, 36L are generally rectangular in shape but with rounded corners. The arms 36R, 36L are integrally formed with the base 32 at the lower ends of the arms 36R, 36L. The arms 36R, 36L freely extend upwardly from the base 32. The tongue 34 is located between the right and left arms 36R, 36L and extends upwardly from the base 32 a further distance than the right and left arms 36R, 36L. The tongue 34 is separated from the left arm 36L by a vertical left anchor body groove 46L, and the tongue 34 is separated from the right arm 36R by a vertical right anchor body groove 46R.
Referring to FIGS. 7 and 8, the retainer 26 is generally elongated from right to left. The retainer 26 includes a U-shaped upper retainer groove 48 formed at its upper end that has a similar width (right to left side) as the width of the load receiving opening 35. The retainer 26 also includes a pair of right and left retainer mounting apertures 50R, 50L. The upper retainer groove 48 is located between the retainer mounting apertures 50R, 50L. A pair of right and left inverted u-shaped lower retainer grooves 52R, 52L are formed at the lower end of the retainer 26.
FIGS. 9 and 10 show one of the locating flanges 28L, 28R. Each of the locating flanges 28L, 28R are of similar construction and function, so for the interest of brevity, one will be described. The locating flange includes a locating portion 54 and a retaining portion 56 located opposite each other and formed in one piece with each other. The locating portion 54 is longer than the retaining portion 56 and extends upwardly and downwardly beyond the retaining portion 56. An upper notch 58U is formed at the upper junction of the locating portion 54 and the retaining portion 56, and a lower notch 58L is formed at the lower junction of the locating portion 54 and the retaining portion 56. FIGS. 11 and 12 show the left and right fasteners 30L, 30R. Each fastener comprises a head screw 60 and a lock nut 62. The head screw 60 may be zinc yellow-chromate plated hex head screw, and the lock nut 62 may be a high-strength steel nylon-insert lock nut. FIG. 19 shows an alternative fastener comprising a clevis pin 80 and cotter pin 82 to removably fasten the retainer 26 to the tic down anchor body 24.
FIGS. 1-4, 13-15, and 17 show all of the elements of the tie down anchor assembly assembled together. Specifically, the locating flanges 28L, 28R are oriented vertically and extend into the right and left slits 44R, 44L such that lower and upper ends 88, 90 (FIG. 5) of the tic down anchor body 24 that define the slits 44L, 44R are received in the respective lower and upper notches 58L, 58U to help secure the locating flanges 28L, 28R to the tie down anchor body 24. The locating flanges 28L, 28R are welded to the tongue 34 to secure the locating flanges 28L, 28R to the tic down anchor assembly 20. The retainer 26 is mounted by the fasteners 30L, 30R to the front of the tic down anchor body 24 at a location above the right and left slits 44R, 44L. In this position, the upper retainer groove 48 is aligned with the load receiving opening 35 such that lower ends of the upper retainer groove 48 and load receiving opening 35 are at the same height. The right and left lower retainer grooves 52R, 52L are aligned over their respective right and left anchor body grooves 46R, 46L as best illustrated in FIG. 3. As seen in FIGS. 1, 13 and 14, a head 61 of the head screw 60 engages the retainer 26 and the lock nut 62 engages the tongue 34 to removably secure the retainer 26 to the tie down anchor body 24.
FIGS. 15, 17 and 18 show an apparatus 63 that has the tie down anchor assembly 20 mounted to the stake bed trailer pocket 22 that has an open ended bottom. As illustrated in FIG. 16, the stake bed trailer pocket 22 is defined by the rear end 64 of the vehicle and right and left side walls 66R, 66L that are interconnected by an outer wall 68. The method to mount the tic down anchor assembly 20 to the stake bed trailer pocket 22 is as follows. First, the locating flanges 28L, 28R are inserted through the slits 44R, 44L such that the locating portion 54 is on one side of the tie down anchor body 24 and the retaining portion 56 is on the opposite side of the tie down anchor body 24. The locating flanges 28L, 28R are then welded to the tic down anchor body 24. Then, the tie down anchor body 24 and locating flanges 28L, 28R are positioned such that the locating flanges 28L, 28R are underneath the pocket opening and the right and left anchor body grooves 46R, 46L are aligned under the right and left side walls 66R, 66L of the stake bed trailer pocket 22. Then, the tie down anchor body 24 is moved upwardly such that the right and left anchor body grooves 46R, 46L slidably receive the right and left side walls 66R, 66L of the stake bed trailer pocket 22.
Then, the retainer 26 is positioned on the tie down anchor body 24 such that the right and left retainer mounting apertures 50R, 50L are aligned with their respective right and left anchor body mounting apertures 42R, 42L, and the right and left lower retainer grooves 52R, 52L are aligned over their respective right and left anchor body grooves 46R, 46L. In this positioned also, the right and left side walls 66R, 66L extend upwardly into the lower right and left retainer grooves 52R, 52L such that the retainer 26 engages the top edge of the right and left side walls 66R, 66L as shown in FIG. 18. Then, the hex head screws 60 are inserted through their respective right and left retainer apertures 50R, 50L of the retainer 26 and right and left anchor body mounting apertures 42R, 42L of the tic down anchor body 24 until the heads 61 of the screws 60 abut the retainer 26. The lock nuts 62 are then threadedly fastened on their respective shanks 70 of the screw 60 and are rotated until they abut the tie down anchor body 24 to clamp the retainer 26 to the tie down anchor body 24. The lower right and left retainer grooves 52R, 52L and the right and left anchor body grooves 46R, 46L surround and engage their respective right and left side walls 66R, 66L of the stake bed trailer pocket 22 to secure the tie down anchor assembly 20 to the stake bed trailer pocket 22 and prevent right and left lateral movement of the tie down anchor assembly 20. The locating flanges 28L, 28R engage the outer wall 68 and rear end 64 to prevent forward and rearward movement of the tie down anchor assembly 20 and help position the tie down anchor assembly 20 within the stake bed trailer pocket 22.
To use the tie down anchor assembly 20, a hook that is attached to a securing strap 74 or other load securing flexible member is hooked around the tip 38 of the tongue 34 to secure the hook to the tie down anchor assembly. Alternatively, if there is no hook, the securing strap 74 may extend through the load receiving opening 35 and over the tip 38 of the tongue 34 to secure the strap 74 to the tie down anchor assembly 20. The tie down anchor assembly 20 utilizes both the mechanical properties of its steel construction and its novel shape to transfer the tension force of the load securing strap 74 (or rope, chain, bungee cord or the like) to the structural frame of a trailer attachment, when towing a load. The tie down anchor wedges into the stake pocket of a stake side bed trailer to provide a robust anchor point for load securing straps such as ratchet straps, load securing chains, bungee cords and other load securing flexible members. The tie down anchor assembly and their elements may have a variety of dimensions. For example, in another embodiment shown in FIG. 20, a tie down anchor assembly 200 is shown having a thicker tie down anchor body 224 and a load receiving opening 235 that has a larger height than that of the tie down anchor body 24 of the tie down anchor assembly 20. All of the other elements of the tie down anchor assembly 200 are similar in construction and function as that of the tie down anchor assembly 20.
Although various embodiments of the disclosed tie down anchor assembly have been shown and described, modifications may occur to those skilled in the art upon reading the specification. The present application includes such modifications and is limited only by the scope of the claims.
