Abstract
A safety hook including a main shaft, a chain receiving portion disposed at a first end of the main shaft, a first bend disposed at a second end of the main shaft, and a second bend depending from the first bend. The chain receiving portion and the first bend are positioned on the same side as the main shaft and are substantially in-line with each other. The second bend bends in substantially the opposite direction of the first bend and has a terminal end that does not extend beyond the first bend.
Description
- The present invention relates to security hooks, and more particularly to a security hook having in-line formed ends to resist unplanned disengagement from a chain or the like.
- “S” hooks have been widely used as security chain end hooks, particularly in the trailer industry. In the trailer industry, chains with S-hooks are used as added security between the trailer and a towing vehicle. In use, these hooks may be engaged in a hole or slot in a vehicle frame, over the flanged edge of a channel-type frame, or with another chain. Oftentimes, the security chain hook is routed through a vehicle tie-down loop or around a frame member with the end hook then engaged over or through a link of the security chain. However, during vehicle operation, vibrations from road conditions or engine operation can cause the S-hook to disengage.
- Different designs have been proposed to prevent disengagement of the S-hook during vehicle operation. For example, an S-hook having a protruding end that extends perpendicularly therefrom is known. The protruding end helps prevent the S-hook from coming disengaged. However, such a design is not always effective.
- A long felt need exists for a security hook that resists unintentional disengagement and overcomes the other disadvantages of the prior art.
- A security hook is disclosed having a main shaft, a chain receiving portion extending from a first end of the main shaft and a first bend extending from a second end of the main shaft. The chain receiving portion and first bend are preferably, but not necessarily, positioned on the same side of the main shaft and are substantially in-line with each other. A second bend extends from the first bend in the opposite direction of the first bend. The security hook, including the main shaft, the chain receiving portion and the first and second bends, is preferably made of an integral metal bar capable of withstanding relatively high forces.
- In one embodiment of the invention, the first and second bends each have a straight portion and the second bend extends from the straight portion of the first bend. The straight portions are substantially parallel to the main shaft. The chain receiving portion also includes a straight portion that is substantially parallel to the main shaft.
- The second bend of the security hook has a free end that preferably does not extend beyond the first bend. In use, the security hook is engaged with a chain connected to a trailer. The chain is received in the chain receiving portion of the hook. The chain receiving portion is preferably dimensioned to limit the movement of the chain therein and to prevent inadvertent disengagement of the chain from the security hook. When installed, the security hook ensures that the trailer remains connected to the towing vehicle.
- Other objects, features and advantages of the present invention will become apparent to those skilled in the art from the following detailed description. It is to be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the present invention, are given by way of illustration and not limitation. Many changes and modifications within the scope of the present invention may be made without departing from the spirit thereof, and the invention includes all such modifications.

- A preferred embodiment of the
security hook 10 of the present invention, as shown inFIGS. 1 through 3 , includes achain receiving portion 12, amain shaft 14, afirst bend 16 and asecond bend 18. Themain shaft 14 has first andsecond opposite ends chain receiving portion 12 is disposed at thefirst end 14 a of themain shaft 14 and is preferably integrally attached to themain shaft 14. In one embodiment of the invention, thechain receiving portion 12 andmain shaft 14 are made of an integral piece of metal bar stock and thechain receiving portion 12 is formed by bending the end of the metal bar stock toward themain shaft 14. - Initially,
arm 12 a of thechain receiving portion 12 extends substantially parallel to themain shaft 14 toward thesecond bend 18. The term “substantially” is defined as “being largely but not wholly that which is specified.” “Substantially parallel” is used herein to indicate components that extend in the same direction in a largely equidistant relationship. However, “substantially parallel” does not require the components to be exactly parallel. Following attachment ofsecurity hook 10 to a chain,arm 12 a is formed further toward main shaft 14 (shown in phantom inFIG. 1 ) to prevent unintended separation ofhook 10 from the chain. In an alternative embodiment, thechain receiving portion 12 is an eye (not shown) welded to themain shaft 14. - As best shown in
FIG. 1 , thefirst bend 16 extends from thesecond end 14 b of themain shaft 14 and includes a firststraight portion 16 a. Preferably, thefirst bend 16 extends upwardly toward the same side of themain shaft 14 as thechain receiving portion 12 such that thefirst bend 16 is arranged vertically in-line with thechain receiving portion 12. “In-line” is used herein to indicate that thechain receiving portion 12 and thefirst bend 16 are positioned on the same side as themain shaft 14, and thefirst bend 16 is positioned generally in a straight vertical line with respect to thechain receiving portion 12. It is to be understood that the term “vertical” is used herein to refer to the orientation of the components as shown inFIG. 3 . It will be further understood that the chain receiving member also may reside on the opposite side of themain shaft 14. - In a preferred embodiment of the invention, the
second bend 18 bends in the opposite direction as thefirst bend 16. As shown inFIG. 1 , thefirst bend 16 bends upwardly from themain shaft 14 and thesecond bend 18 bends downwardly from the firststraight portion 16 a. Thesecond bend 18 extends from the firststraight portion 16 a and includes secondstraight portion 18 a that terminates in ahook end 22. In one embodiment of the invention, thesecond bend 18 extends directly from thefirst bend 16, eliminating the firststraight portion 16 a. Similarly, the secondstraight portion 18 a can be eliminated causing the second bend to terminate in ahook end 22. - In a preferred embodiment, as shown in
FIG. 1 , the firststraight portion 16 a is substantially parallel with themain shaft 14, and the secondstraight portion 18 a is substantially parallel with the firststraight portion 16 a and themain shaft 14. As best shown inFIGS. 4 and 6 ,arm 12 a is not parallel to themain shaft 14, but is inclined such that theend 26 ofarm 12 a is approaching themain shaft 14. Agap 24 is defined between thearm 12 a and themain shaft 14.Gap 24 is preferably dimensioned to prevent separation of receivingportion 12 from a chain and to restrict the inadvertent disengagement of a chain fromfirst bend 16 ofsecurity hook 10. - The
security hook 10 can be made of any rigid material, such as metal, plastic, composite, etc. The material used to form thesecurity hook 10 preferably has a yield strength sufficient to withstand loads required of a trailer security chain hook. In a preferred embodiment of the invention, thesecurity hook 10, including thechain receiving portion 12, themain shaft 14, thefirst bend 16, and thesecond bend 18, is preferably formed from a single integral metal bar. Alternatively, the elements of thesecurity hook 10 can be separately made and thereafter welded together. - The security hook preferably has a circular cross-section, as best shown in
FIG. 2 . The cross-section, however, is not limited to the embodiment shown but can be of any shape, including, oval, rectangular or any other shape. As best shown inFIG. 3 , themain shaft 14, first bend 16 (including the firststraight portion 16 a), and the second bend 18 (including the secondstraight portion 18 a) are co-planar and define a plane P. - In a preferred embodiment of the invention, as best shown in
FIG. 1 , hookend 22 does not extend beyond (or below) thefirst bend 16. The lower limit of thefirst bend 16 is illustrated inFIG. 1 by line L which extends along the bottom edge of thefirst bend 16. If hook end 22 extended beyond line L, the use of thesecurity hook 10 in certain applications would be limited. For example, as shown inFIG. 7 ,security hook 10 is used to connect achain 102 extending from atrailer 116 to aplatform 114 of a towingvehicle 118. A preferred method of connecting thechain 102 to the towingvehicle 118 using thesecurity hook 10 is now described in reference toFIGS. 4 and 7 . To engage thesecurity hook 10 with theplatform 114, thehook end 22 of thesecurity hook 10 is inserted into thehole 112. The security hook is pivoted downwardly to allow the secondstraight portion 18 a to enter thehole 112 until thesecond bend 18 is received in thehole 112. At such point as the first and secondstraight portions platform 114, thesecurity hook 10 is pivoted further downwardly such that the firststraight portion 16 a is received in thehole 112. Once thefirst bend 16 rests atop theplate 114, the process is completed and thesecurity hook 10 is at rest in the position shown inFIG. 4 . A person skilled in the art can modify the steps of installing the security hook on the platform without departing from the scope of the present invention. - In a preferred embodiment of the invention, when the
security hook 10 is properly installed,hook end 22 rests on the underside 114 a of theplatform 114 and themain shaft 14 extends in a substantially perpendicular relationship to theplatform 114. If thehook end 22 extended beyond line L (shown inFIG. 1 ), thesecurity hook 10 could not be positioned on theplatform 114 as depicted inFIG. 4 . Rather, the security hook would rest in an awkward and inefficient position. - The use of the
security hook 10 to connect achain 102 from atrailer 116 to theplatform 114 of a towingvehicle 118 is described for exemplary purposes only. It will be understood that those skilled in the art that there are numerous other uses of the security hook of the present invention. - Referring now to
FIGS. 8-13 , another preferred embodiment of asecurity hook 50 in accordance with the present invention is shown. In this embodiment, themain shaft 14 of thesecurity hook 50 includes aprotrusion 52 thereon. Thechain receiving portion 12 has anotch 54 defined on an inside surface thereof. Thenotch 54 is preferably defined where thearm 12 a meets the remainder of thechain receiving portion 12, as is shown inFIG. 8 . - In a preferred embodiment, the
arm 12 a defines an open position (as shown inFIG. 8 ) and a closed position (as shown inFIG. 10 ). Prior to use, thearm 12 a is in the open position. A chain is placed on thechain receiving portion 12 and then thearm 12 a is further formed to the closed position. It will be appreciated that thearm 12 a will form predictably to the closed position due to the reduced cross-sectional area at thenotch 54. - It will also be appreciated that the
protrusion 52 is positioned such that when thearm 12 a is formed to the closed position that thearm 12 a (chain receiving portion 12) andprotrusion 52 cooperate to ensure that the chain cannot come out or off of thechain receiving portion 12, i.e., the space between the end of thearm 12 a and theprotrusion 52 is of a smaller dimension than the cross-sectional width of the chain. Preferably, theend 52 a of the protrusion is also wider than themain shaft 14. This can be best seen inFIGS. 9 and 13 . - In a preferred embodiment, the
protrusion 52 has the cross-sectional shape shown inFIG. 13 . However, it will be understood that theprotrusion 52 can have any cross-sectional shape that cooperates with the arm to prevent the chain from coming off of thechain receiving member 12. - Referring now to
FIGS. 14-20 , another preferred embodiment of asecurity hook 70 in accordance with the present invention is shown. In this embodiment, themain shaft 14 of thesecurity hook 70 includes aprotrusion 72 with the cross-sectional shape shown inFIG. 20 . - As shown in
FIGS. 21-24 , another preferred embodiment of thesecurity hook 200 of the present invention includes achain receiving portion 212, amain shaft 214 and afirst bend 216. Themain shaft 214 has afirst end 218 and a secondopposing end 222. Thechain receiving portion 212 is preferably integrally attached to themain shaft 214 at thefirst end 218 and thefirst bend 216 is preferably integrally attached to themain shaft 214 at thesecond end 222. In a preferred embodiment of the invention, as shown inFIGS. 21-23 , thesecurity hook 200 includes a blockingmember 220. Blockingmember 220 preferably protrudes from themain shaft 214 toward anarm 224 of thechain receiving portion 212 and is configured to prevent a chain from exiting thechain receiving portion 212 of thesecurity hook 200. - As shown in
FIG. 21 , the blockingmember 220 preferably has aninclined surface 230, and has a tapered shape. When the chain is being installed on thesecurity hook 200, theinclined surface 230 aids in the alignment of the chain with thechain receiving portion 212, thereby facilitating the installation of the chain in thechain receiving portion 212. Once the chain is installed, as shown inFIG. 24 . upon angular movement of the chain with respect to thesecurity hook 200, the blockingmember 220 restricts the movement of the chain making it impossible for the chain to become disengaged from thesecurity hook 200. - As shown in
FIGS. 25 and 26 , the blockingmember 220 prevents disengagement of the chain from the security hook even if the security hook is installed over a chain link rather than through a chain link. In a preferred embodiment of the invention, thearm 224 of thesecurity hook 200 has a taperedinner surface 232. Thetapered surface 232 gives the security hook 200 a slightlylarger opening 234 at the entry end, but pushes the chain link closer to the blockingmember 220 once the chain is inserted through theopening 234. - As shown in
FIG. 26 , in another preferred embodiment of the present invention,security hook 200 includes asecond blocking member 240. Thesecond blocking member 240 is preferably positioned in an opposite facing relationship with thefirst blocking member 220. The first and second blockingmember chain receiving portion 212, thus ensuring that the chain remains engaged with thechain receiving portion 212. - The embodiments of the present invention recited herein are intended to be merely exemplary and those skilled in the art will be able to make numerous modifications to them without departing from the spirit of the present invention. For example, the first and second
straight portions straight portions main shaft 14; theend portion 22 may extend beyond thefirst bend 16. All such modifications are intended to be within the scope of the present invention as defined by the claims appended hereto.
