Abstract
A trunk tie-down has a catch that releasably couples with a strike of a vehicle lock mechanism, and a latch connected with the catch, that releasably couples with an opposing catch of the vehicle lock mechanism. The latch may have a first latch portion and an opposing second latch portion, each being generally U-shaped with a bight and a pair of legs. The legs of the first and the second latch portions extend toward each other and are coupled together. The bight of the first latch portion may also lie in a first reference plane while the bight of the second latch portion lies in a second reference plane. The first and the second reference planes may be perpendicular. Each of the first and the second latch portion bights may have a dimension of thickness with the second latch portion bight being thicker than the first latch portion bight. The latch may be connected with the catch so that the latch is oriented with one of the first and the second latch portions positioned toward the catch and the latch extending generally away from the catch to the other of the second and first the latch portions. The tie-down may also include an elongated member interposed between and interconnecting the latch and the catch. Alternatively, the tie-down may have a first tie end and an opposing second tie, a catch, and a latch connected with the catch. The catch may have an aperture that extends through the catch along a line. The catch may be located at the first tie end. The latch may have a generally U-shaped portion with a bight and a pair of legs. The U-shaped portion may define a reference plane that is preferably not perpendicular to and is most preferably parallel with the line. The latch may be at the second tie end.

BACKGROUND OF THE INVENTION




The invention relates to tie-downs and in particular to a tie-down that engages the opposing catch and latch of a vehicle trunk lid, for example.




People commonly use cars and other vehicles to transport items that are too large to fit within the vehicle. Thin cords or even string is frequently used to tie a load of oversized items to vehicles. Probably most common is a situation where an oversized item is placed in a car trunk. In such a case, the trunk lock cannot be latched and the trunk must be left open. This may include the back door of the so called hatch back vehicles, as well as the single back door of many mini-vans, for example. The options at this point are generally limited.




One may merely let the trunk lid bounce against the load as the wind of driving forces the lid downward and bumps in the roadway jounce the lid upward. This may damage both the load and the vehicle. The load may also bounce out of the trunk.




Alternatively, one may attempt to tie the trunk lid down against the load with a cord or the like. Many vehicles do not provide convenient tying points for this purpose, however. Also, if a place to tie a cord can be found, it often will have a metal edge that will likely chafe and cut a cord and especially a string.




Too often, the typical make shift attempts at transporting oversized items fail and the load is accidentally unloaded, this is, spilled over the roadway. The potential for accident, damage to property, and harm to persons is real and readily apparent. Thus, a need for safely securing oversize loads does exist and is not adequately addressed.




BRIEF SUMMARY OF THE INVENTION




Accordingly, a trunk tie-down of the invention has a catch that releasably couples with a strike of a vehicle lock mechanism, and a latch connected with the catch, that releasably couples with an opposing catch of the vehicle lock mechanism. The latch may have a first latch portion and an opposing second latch portion, each being generally U-shaped with a bight and a pair of legs. The legs of the first and the second latch portions extend toward and are connected with each other.




In further aspects of the invention, the bight of the first latch portion may lie in a first reference plane while the bight of the second latch portion may lie in a second reference plane. The first and the second reference planes are most preferably perpendicular.




Each of the first and the second latch portion bights may have a dimension of thickness with the second latch portion bight being thicker than the first latch portion bight. The latch may be connected with the catch so that the latch is oriented with one of the latch portions positioned toward the catch and the latch extending generally away from the catch to the other latch portion. The tie-down may also include an elongated member interposed between and interconnecting the latch and the catch. The elongated member may be length adjustable.




In other aspects of the invention, the tie-down may have a first tie end and an opposing second tie, a catch, and a latch connected with the catch. The catch may have an aperture that extends through the catch along a line. The catch may be located at the first tie end. The latch may have a generally U-shaped portion with a bight and a pair of legs. The U-shaped portion may define a reference plane that is preferably not perpendicular to and is most preferably parallel with the line. The latch may be at the second tie end.




These and other features, objects, and benefits of the invention will be recognized by one having ordinary skill in the art and by those who practice the invention, from the specification, the claims, and the drawing figures.

DETAILED DESCRIPTION OF THE INVENTION




Preferred embodiments of a trunk tie-down according to the invention are generally shown in the drawing figures and discussed below. A trunk tie-down first embodiment


100


of the invention is shown in position between the opposing catch


22


and latch


24


of an open trunk


26


of a car


28


or the like (FIG.


1


). More particularly, the tie-down


100


has a catch


122


that is connected with a latch


124


. Preferably, the catch


122


and latch


124


are interconnected with an adjustment strap


126


.




The adjustment strap


126


may be an elongated member that is preferably length adjustable and may include a first piece of web strap


132


that is coupled with the latch


124


, a buckle


134


that is coupled with the trap


132


, and a second piece of web strap


136


that is coupled between the buckle


134


and the catch


122


(FIGS.


2


and


3


). The web strap


132


and


136


may be an about one to one and a half inch (25 to 38 mm) fabric web strap as is commonly known. The buckle


134


may be a common spring loaded cam buckle that is sized to match the strap as shown. Of course, the particular material and construction of either the strap


132


or the buckle


134


may vary according to the requirements of a user or manufacturer. For example, a cord may substitute for the strap


132


and the strap or cord may be made to conduct an electric current or not, also a variety of length adjustment device may be substituted for the buckle


134


, including without limitation, a double ring arrangement, as is well known. The strap


132


may be provided with a grasping loop


138


, which facilitates cinching the tie-down snug, as shown.




The catch


122


may be any suitable clasp or hook, preferably with a keeper. The catch


122


preferably defines an aperture


142


that extends through the catch along a line


144


(FIG.


3


). A common snap hook, as shown, has been found to work well. A clasp or hook with a keeper is preferred so a user may releasably capture the strike or latch


24


of a trunk in the catch


122


, and more particularly in the aperture


142


. The trunk strike


24


is preferably captured in the aperture


142


until intentionally released, so the tie-down


100


will not merely fall from or otherwise disengage the vehicle strike


24


.




The latch


124


is substantially an elongated annular member. The latch has first and second latch portions


152


and


154


, respectively, that are each generally U-shaped with a bight


156


and


158


, respectively, and a pair of legs


162


-


168


, respectively (FIG.


4


). Each of the first and the second latch portions


152


and


154


, respectively, generally defines a reference plane. This is illustrated in drawing

FIG. 4

by the use of normal lines


172


and


174


, respectively. Thus, normal line


172


extends perpendicular to the first latch portion


152


, while normal line


174


extends perpendicular to the second latch portion


154


. Further, the first and second latch portions


152


and


154


, respectively, are most preferably perpendicular to one another. It is further noted that the normal line


172


is also most preferably perpendicular to the line


144


of the catch


122


.




A more elementary concept of the latch


124


is that it may be a twisted oval. Regardless, the latch


124


is preferably formed with a given clearance between the legs


162


-


168


, so the strap


126


may be slipped from the second bight


154


to the first bight


152


, or visa versa.




While the catch


122


is adapted to capture the strike


24


of a trunk lock, for example, the latch


124


is adapted to be captured in the trunk lock catch


22


. Thus, at least some of the dimensions of the latch


124


are dictated by function with the trunk catches of various vehicle manufacturers. While some exemplary dimensions are provided below, one having ordinary skill in the art will understand that the dimensions given are exemplary and that alternative dimensions may be substituted without departing from the invention or the spirit of the disclosed concept. Thus, the latch


124


is preferably formed from a length of about three sixteenths inch (4.7 mm) wire or the like. The wire is looped into an annular member and ends of the wire are most preferably welded or otherwise fastened to maximize the strength of the latch


124


. The inventors have found that an overall length of the annular member of roughly about four and three quarters inches (121 mm) and a width of roughly about one and three eighths inches (35 mm) provides a latch


124


that falls easily to hand and is confidently manipulated by a user. For similar reason, the two latch portions


152


and


154


may be proportioned relative to the overall length of the latch


124


, in the range of about one-to-one to about three-to-one.




While dimensioning the wire diameter at about three sixteenths inch (4.7 mm) will accommodate a great number of current vehicle trunk locks and the like, more vehicles are accommodated when at least a segment


176


the first latch portion


152


is struck or the like to a thickness of about one eighth inch (3.2 mm). Even more vehicles are accommodated when at least a segment


178


of the second latch portion


154


is enlarged to a diameter of about seven sixteenths inches (11 mm) (FIG.


5


). The segment


178


may be made relatively thicker by various constructions, including and not limited to the use of an overlaying sleeve, which may be fixed or removable.




In use, the catch


122


is opened and clasped over the vehicle strike


24


, which releasably couples the catch


122


with the vehicle strike


24


. The latch


124


is inserted into the vehicle catch


22


and captured by the vehicle catch in place of the vehicle latch


24


. One having ordinary skill in the art will understand that convenience of using the tie-down


100


is enhanced by having the catch


122


capture the vehicle strike


24


and not be left to fall free from the strike. As discussed above, a relative distance between the catch


122


and the latch


124


may vary when in use as a trunk lid may bounce against an over size load as the wind of driving forces the lid downward and as bumps in the roadway jounce the lid. Thus, one having ordinary skill in the art will understand the desirability of having both of the tie-down catch


122


and latch


124


being securely engaged with the corresponding vehicle latch


24


and catch


22


for various reasons, including and not limited to safety issues and property damage issues.




Depending upon the requirements of the vehicle catch


22


, the latch


124


is positioned with one of the two latch portions


152


and


154


positioned at the strap


132


and the other of the two latch portions


152


and


154


extending away from the strap


132


. If an opposing orientation of the latch


124


is desired, the strap


132


is slid along the latch


124


to the other latch portion


152


or


154


. Once oriented as desired, the end of the latch


124


that extends away from the strap


132


is pressed into the vehicle catch


22


in locking engagement.




With both of the catch


12


and the latch


124


engaging their respective vehicle counterparts, namely the strike


24


and catch


22


, the end or loop


136


of the strap


126


may be pulled and the tie-down snugged. Release of the tie-down is merely a matter of actuating the vehicle lock, whereby the latch


124


is released from the trunk lock catch


22


. The tie-down catch


122


is removed from the vehicle latch


124


by merely reversing the engaging process. Lengthening the strap


126


is provided by manipulation of the buckle


134


, as one having ordinary skill in the art will understand.




A first alternative latch


224


(

FIGS. 5 and 6

) is substantially the same as the first latch


124


. The second latch


224


is also a twisted annular member and has bights


256


and


258


of latch portions


252


and


254


, respectively. The latch


224


differs in that the thickened bight


258


is formed by wrapping ends of a wire that is used to fabricate the latch


224


.




A second alternative latch


324


(

FIGS. 7 and 8

) is substantially similar to the first latch


124


. The third latch


324


is a twisted annular member with latch portions


352


and


354


and bights


356


and


358


, respectively.




A third alternative latch


424


(

FIGS. 9 and 10

) is also substantially similar to the first latch


124


. The fourth latch


424


is a twisted annular member with bights


456


and


458


of latch portions


452


and


454


, respectively.




A fourth alternative latch


524


(

FIGS. 11 and 12

) is similar to the first latch


124


. The fifth latch


524


is also a twisted annular member with bights


556


and


558


of latch portions


552


and


554


, respectively. The latch


524


is twisted to the point of wrapping together the legs of the latch portions


552


and


554


, however. Thus, the strap will not slide between the two latch portions


552


and


554


, respectively. Versatility of the latch


524


may be enhanced with a removable over laying sleeve, as discussed above, that is positioned at the bight


556


.




A fifth alternative latch


624


(

FIGS. 13 and 14

) is similar to the first latch


124


. The sixth latch


624


is a pair of annular members


602


and


604


with bights


656


and


658


of latch portions


652


and


654


, respectively. The annular members


602


and


604


are noted to define distinct reference planes. The annular members


602


and


604


may be oriented generally perpendicular to one another. Utility of the latch


624


with a great number of differing vehicle locks may be enhanced by thickening a bight


682


with a thicker material or with an over laying sleeve, as discussed above.




A sixth alternative latch


724


(

FIG. 15

) is similar to the sixth latch


624


. The seventh latch


724


has a pair of annular members


702


and


704


. The annular members


702


and


704


are noted to define distinct reference planes with normal lines


706


and


708


, respectively. The annular members


702


and


704


may be oriented generally perpendicular to one another. The annular member


702


includes bights


756


and


758


of latch portions


752


and


754


, respectively. Utility of the latch


724


with a great number of differing vehicle locks may be enhanced by thickening a bight


748


with a thicker material or with an over laying sleeve, as discussed above.




A first alternative tie-down


800


has an annular member or latch


824


connected with a catch


822


(FIG.


16


). The latch


824


also has first and second latch portions


852


and


854


, respectively. Each latch portion


85


and


854


includes a bight


856


and


858


and a pair of legs


862


-


868


. At least one of the latch portions


852


and


854


defines a first reference plane with a normal line


872


. The catch


822


may be substantially similar to the catch


122


discussed above. Thus, the catch


822


also defines an aperture that extends through the catch along a line


874


. It is noted that the lines


872


and


874


are generally askew and most preferably lie in perpendicular planes. Utility of the tie-down


800


with a great number of differing vehicle locks may be enhanced by thickening the bight


858


with a thicker material or with an over laying sleeve, as discussed above.
