Definitions
- the present invention relates to a device for collection and storage of the free, non-active, portion of a strap of a manually operated cargo tightener which is used to secure cargo to be transported.
- the typical prior art cargo tightener which is modified to make the present invention, includes a shaft provided at one end of a connecting link or arm.
- the shaft is journaled in one end of the connecting arm, thus providing for rotatable attachment of a lever to the connecting arm.
- a first, or short, strap is firmly secured to a bolt or pin in the other end of the connecting arm, and has at its free end, a hook or other device for attachment to a vehicle transporting the cargo.
- a second strap has a hook or other device at one of its ends.
- the hook is attached to the transportation vehicle.
- the other end, or free or non-active end, of the second strap is inserted through a slot in the rotatable shaft.
- a ratchet arrangement permits tightening of the strap by back and forth movement of the lever with respect to the connecting link. Because the connecting arm or link is held firmly in place by the first strap, the second strap tightens down over the cargo.
- the cargo tightener is conventional and, therefore, will riot be described in any great detail except with regard to the modification of the lever to provide the strap collector portion of the present invention.
- a common problem when using the above mentioned cargo tightener with tensioning straps concerns the handling of the free end of the strap not used when securing the cargo.
- This strap portion has to be thoroughly secured to the cargo in order not to flutter in the encountering wind, or to trail on the ground, both cases leading to a hasty soiling and wearing down of the strap.
- a freely fluttering strap is a danger to traffic, particularly in connection with the wider 24 to 30 foot long straps used professionally by haulage contractors.
- US Patent Publication No. US 2004/0094650 A1 to Huang shows a strap fastener system including a strap fastener for fastening a belt, and a winding device for winding the strap.
- the winding device includes a housing which is attached to a connecting arm portion of the typical prior art cargo tightener.
- a reel is put in the housing for winding the strap, and a torque spring is arranged between the reel and the control device for automatically rotating the reel in the non-rotational position of the control device.
- U.S. Pat. No. 5,611,520 to Söderström shows a strap collector which is designed to be attached to the connecting arm of a standard cargo tightener.
- the strap collector includes a magazine for the protection and storage of the long tensioning strap of the cargo tightener when wound to the shaft of the strap collector.
- U.S. Pat. No. 6,609,275 B1 to Lin shows a strap tightener with an auto pulling device connected to a seat.
- the auto pulling device includes a housing and a reversing device.
- the reversing device is rotatably received in the housing.
- the housing would correspond to a connecting arm portion of a prior art cargo tightener.
- U.S. Pat. No. 6,102,371 to Wyers shows a strap tensioning and collection device having a variable length strap and a fixed length strap operatively associated with the strap storage section, and a strap tensioning section.
- German Offenlegungsschrift DE 36 39 712 A1 to Kinnert shows a tensioning ratchet, in particular for belts, which is equipped with a ratchet body having a retaining bolt for fastening a safety belt, and having a ratchet lever which is mounted at the other end of the ratchet body so as to be rotatable about the axle of a slotted roller for fastening the end of a tensioning belt to be wound thereon.
- the aim of the present invention is to provide a cargo tightener and strap collector which is more cost effective compared with prior art devices, is less bulky, and is easier to manufacture. This is accomplished by having the strap collector on the lever portion of the cargo tightener, rather than on the connecting arm segment, as in the prior art.
- FIG. 1 is a perspective view of a prior art cargo tightener.
- FIG. 2 is an end elevational view of a cargo loaded on a platform showing how the prior art cargo tightener of FIG. 1 is fastened to hold a load in position, and illustrating the free end or tail of the ratchet strap that is left to be dealt with after the cargo tightener is tightened to the desired extent.
- FIG. 3 is a view similar in part to FIG. 2 , but illustrating the use of a construction embodying the present invention, and showing how the problem of the ratchet strap tail is solved by the present invention.

- FIG. 8 is a diagrammatic cross-sectional view of the construction shown in FIG. 7 illustrating how the ratchet strap is fed through the device.
- FIG. 9 is an enlarged view, partly in section, of the construction shown in FIG. 7 , illustrating how the ratchet strap tail may be wound on the handle by turning the right hand knob, as long as the left hand knob has not been tightened.
- FIG. 10 is a view, similar in part to FIG. 9 , illustrating how the right hand knob can not be turned further once the left hand knob is tightened against the sidewall, thus securing the ratchet tail in place during transport of a load.
- FIG. 1 there is shown a prior art cargo tightener and strap collector, generally designated by the numeral 10 .
- the cargo tightener and strap collector 10 comprises a connecting arm or link 12 , and a lever or arm 14 .
- a strap 15 is provided with a hook 16 at one end thereof for connection to a transportation vehicle (not shown).
- the other end of strap 15 is firmly held to connecting arm 12 by pin 17 . Reciprocal motion of lever 14 using handle 18 will cause shaft 19 to rotate due to the ratchet and pawl assembly 13 .
- FIG. 2 there is shown the prior art cargo tightener and strap collector 10 in a typical use situation, attached to a cargo platform 11 , usually of a movable type, and tightened about a load L to secure or tighten it in position. While the cargo platform is usually of the movable type, such as a trailer which may be pulled by a truck or tractor, cargo tightener and strap collector 10 may also be used to secure stationary loads.

- cargo tightener and strap collector 10 may also be used to secure stationary loads.
- Second strap 15 A has at one end a second hook 16 A attached to cargo platform 11 .
- the other end of second strap 15 A is threaded through an opening or slot 19 A in shaft 19 , which is caused to rotate by reciprocal motion of lever 14 using handle 18 . This will cause shaft 19 to rotate due to the ratchet and pawl assembly 13 .
- a portion of second strap 15 A intermediate its' ends will wind around shaft 19 , a large portion or tail 15 B will remain loose, and must be secured for safe transit of load 13 .
- ratchet strap tail 15 B is a serious problem in the art as there is no readily available and cost effective place to store it. Usually the person placing the load 13 on platform 16 will simply wind the tail 15 B around a portion of second strap 15 A. Many times the tail 15 B will be tied in a loose knot around the second strap 15 A. No matter what solution is tried, the tail 15 B frequently becomes loose during transit of the load 13 and flaps in the breeze as the load L is transported down the road, causing a hazard to surrounding drivers and pedestrians. Since many cargo tighteners are usually needed to secure load 13 to platform 11 , many tails 15 B may be causing a hazard at the same time.
- the present invention relates to a modification of the prior art lever or arm 14 to solve the problems of the prior art.
- new reference numerals are used when referring to the present invention.
- the improved cargo tightener and strap collector 20 now provides for storage of the strap, now referred to by the numeral 50 , on the arm or lever 24 .
- the tail 50 A in the form of roll 52 , eliminating the problems of the prior art in a manner to be fully described hereinafter.
- An improved apparatus for tightening and collecting a strap, or strap collector, or combination cargo tightener and strap collector 20 includes a connecting arm or link 22 and a lever 24 .
- Connecting arm 22 extends in a longitudinal direction, and may be substantially similar to the connecting arm 12 shown in the prior art construction of FIG. 1 . It is a modification to the lever of the prior art construction, identified by the numeral 24 , which provides a novel cargo tightener and strap collector 20 .
- a first shaft 26 journaled for rotation in one, or first, end 22 A of the connecting arm 22 .
- a pin 23 to which a first, or short, strap 25 is attached.
- a first hook or fastening means or fastening device 27 is attached to the other end of the strap 25 . In use, the hook 27 will be attached to the transportation vehicle on which the cargo being tightened is being transported.
- first shaft 26 Journals for first shaft 26 , as well as second shaft 40 , are provided by opposed apertures provided in a first pair of spaced apart sidewalls 36 provided in connecting arm 22 , and a second pair of spaced apart sidewalls 37 in the lever 24 .
- a second shaft 40 has provided therein second slot 42 ( FIG. 4 ) to accept a free end, i.e., the end without the second hook 54 , of a second belt 50 , as hereinafter described.
- At least a first portion 40 A of shaft 40 may extend beyond at least one of the second pair of sidewalls 37 ( FIG. 2 ) so that a knob 44 may be attached thereto for rotation of the second shaft 40 .
- a first portion and a second portion ( 40 A, 40 B) of the second shaft 40 will extend beyond the second pair of spaced apart sidewalls 37 , and a knob 44 will be attached to each portion of the second shaft.
- Reciprocal rotation of the lever 24 will cause co-rotational rotation of the first shaft 26 by virtue of a pair of ratchet wheels 60 which are mounted on the first shaft 26 between the first pair of sidewalls 36 and the second pair of spaced apart sidewalls 37 . It is preferred that two ratchet wheels 60 be used, although one may possibly be used.
- Pawl 61 aides in the rotation of the first shaft 26 by operating on the ratchet wheel 60 .
- the pawl 61 is spring loaded and slides in a pair of opposed slots 64 ( FIG. 4 ) in the second pair of opposed sidewalls 37 .
- Second, or long, strap 50 is provided having second hook 54 provided at one end thereof.
- the free or non-active end of strap 50 so referred to because it has no connection to second hook 54 , is first passed through first slot 32 and then inserted in second slot 42 ( FIG. 4 ).
- Second shaft 40 is then rotated, with the aid of knobs 44 , to roll up free end of strap 50 into a roll 52 .
- Second hook 54 In use second hook 54 , and second strap 50 , are completely unrolled and removed from second shaft 40 .
- Second hook 54 is attached to the transportation vehicle on which the cargo is to be transported, at the appropriate location.
- the free end of the strap 50 is placed through first slot 32 in first shaft 26 , and the lever 24 is reciprocally rotated, causing co-rotational movement of the first shaft 26 . Since the first strap 50 is inserted in the first slot 32 , and the connecting arm 22 is restrained by the first strap 25 and the first hook 27 , the cargo tightener and strap collector 20 is tightened down on the cargo.
- the free end of the second strap 50 is inserted in the second slot 42 in the second shaft 40 and the knobs 44 are rotated to take up any slack in the strap before the cargo is transported.
- the free end of the strap of the second strap 50 may be left inserted in the second slot 42 in the second shaft 40 , and the second strap 50 along with second hook 54 may be pulled out, causing the roll 52 to unwind until the second hook 54 may be attached to the transportation vehicle in the appropriate spot.
- the lever 24 is then reciprocally rotated causing co-rotational movement of the first shaft 26 , and the tightening of the cargo tightener and strap collector 20 on the cargo (not shown) in the manner previously described. Any slack in the second strap 50 is taken up by rotating the knob or knobs 44 until the slack is removed.
- the lever 24 is provided with a first substantially linearly extending portion 70 , and a second linearly extending portion 71 extending at an angle with respect to the first portion 70 , thus elevating the roll 52 away from the cargo by elevating the second shaft 40 away from the cargo.
- a pair of diverging portions 72 of the second pair of sidewalls 37 may be interposed between the first linearly extending portion 70 and the second linearly and angularly extending portion 71 of each of said second pair of sidewalls 37 .
- Threaded shaft 80 is used in place of the second shaft 40 .
- Threaded shaft 80 may be hollow, or at least partially hollow, and may have internal or external threads for the purposes described below.
- threaded shaft 80 is hollow, and has an aperture, opening, or hollow portion 82 .
- Aperture 82 may include first portion or first threaded portion 84 , and second portion or second threaded portion 86 , of threaded shaft 80 . Threaded shaft 80 will still have slot 42 provided therein to receive ratchet tail 50 A in the manner described above.
- First threaded portion 84 and second threaded portion 86 of threaded shaft 80 may be of the same or different diameters, as desired. It is preferable that the apertures in the second pair of sidewalls 37 be slightly larger than the diameter of the adjacent threaded portions ( 84 , 86 ) of the threaded shaft 80 to accept a first threaded fastener 88 and a second threaded fastener 90 .
- the first threaded fastener 88 is of a smaller diameter than the second threaded fastener 90 , so the first sidewall aperture 37 A is of a smaller diameter that the second sidewall aperture 37 B, and both are larger than their respective fasteners to allow free rotation of first threaded fastener 88 and a second threaded fastener 90 with respect to the associated aperture.
- First threaded fastener 88 which may be of any type well known in the art, is secured for non-rotation with respect to first rotatable knob 92 by any known means. In other words, when first rotatable knob 92 is rotated, first threaded fastener 88 rotates. First threaded fastener 88 is also fixed with regard to first threaded portion 84 of threaded shaft 80 .
- first sidewall aperture 37 A is larger than first threaded fastener 88 , and first threaded fastener 88 is fixed with regard to first rotatable knob 92 and first threaded portion 84 , when first rotatable knob 92 is rotated, threaded shaft 80 will rotate as long as second rotatable knob 94 is not tightened against a sidewall 37 .
- Second threaded fastener 90 is also fixed with regard to its' respective threaded portion (second threaded portion 86 ) of aperture 82 .
- second rotatable knob 94 is not fixed with respect second threaded fastener 90 but, instead, is able to rotate with respect thereto because second rotatable knob 94 has a threaded aperture 96 with threads complementary to those found on second threaded fastener 90 .
- rotation of second rotatable knob 94 will move it toward and away from respective sidewall 37 .
- second rotatable knob 94 is positioned in its loosened position, as shown in FIG. 9 .
- Ratchet tail 50 A is inserted in slot 42 , and first rotatable knob 92 is rotated, which rotates threaded shaft 80 , which causes ratchet tail 50 A to be wound on threaded shaft 80 until it is wound up to form roll 52 .
- second rotatable knob 94 is rotated until it is tight against sidewall 37 , and sidewall 37 is tight against hollow shaft 80 , thus preventing any further rotation of the threaded shaft 80 by the first rotatable knob 92 .
- the scope of the present invention is not limited to the use of threaded fasteners and knobs, as any rotation mechanism by which the threaded shaft 80 can be rotated, and then selectively be prevented from rotation, is well within the scope of the present invention. Many rotation mechanisms and/or rotation means are known in the art which are suitable for use in the present invention.
- the threaded shaft 80 journaled for rotation between the second pair of spaced apart sidewalls 37 of the lever 24 may have a first threaded portion 84 to accept a first rotation mechanism 98 , and a second threaded portion 86 to accept a second rotation mechanism 100 .
- the first means of rotation 98 is operable to rotate the threaded shaft 80
- the second means of rotation 100 is operable to restrain or permit rotation of the threaded shaft 80 .

No. 11/227,313 is pending as of the filing date of the present application. application Ser. No. 11/227,313 is specifically incorporated herein in its entirety, and priority thereto is claimed.
- 1. Field of Invention
- The present invention relates to a device for collection and storage of the free, non-active, portion of a strap of a manually operated cargo tightener which is used to secure cargo to be transported.
- 2. Description of the Related Art
- The typical prior art cargo tightener, which is modified to make the present invention, includes a shaft provided at one end of a connecting link or arm. The shaft is journaled in one end of the connecting arm, thus providing for rotatable attachment of a lever to the connecting arm. A first, or short, strap is firmly secured to a bolt or pin in the other end of the connecting arm, and has at its free end, a hook or other device for attachment to a vehicle transporting the cargo.
- A second strap has a hook or other device at one of its ends. The hook is attached to the transportation vehicle. The other end, or free or non-active end, of the second strap is inserted through a slot in the rotatable shaft. A ratchet arrangement permits tightening of the strap by back and forth movement of the lever with respect to the connecting link. Because the connecting arm or link is held firmly in place by the first strap, the second strap tightens down over the cargo. The cargo tightener is conventional and, therefore, will riot be described in any great detail except with regard to the modification of the lever to provide the strap collector portion of the present invention.
- A common problem when using the above mentioned cargo tightener with tensioning straps concerns the handling of the free end of the strap not used when securing the cargo. This strap portion has to be thoroughly secured to the cargo in order not to flutter in the encountering wind, or to trail on the ground, both cases leading to a hasty soiling and wearing down of the strap. Further, a freely fluttering strap is a danger to traffic, particularly in connection with the wider 24 to 30 foot long straps used professionally by haulage contractors.
- Many attempts to solve these problems are known in the prior art. US Patent Publication No. US 2004/0094650 A1 to Huang, shows a strap fastener system including a strap fastener for fastening a belt, and a winding device for winding the strap. The winding device includes a housing which is attached to a connecting arm portion of the typical prior art cargo tightener. A reel is put in the housing for winding the strap, and a torque spring is arranged between the reel and the control device for automatically rotating the reel in the non-rotational position of the control device.
- U.S. Pat. No. 5,611,520 to Söderström, shows a strap collector which is designed to be attached to the connecting arm of a standard cargo tightener. The strap collector includes a magazine for the protection and storage of the long tensioning strap of the cargo tightener when wound to the shaft of the strap collector.
- U.S. Pat. No. 6,609,275 B1 to Lin, shows a strap tightener with an auto pulling device connected to a seat. The auto pulling device includes a housing and a reversing device. The reversing device is rotatably received in the housing. The housing would correspond to a connecting arm portion of a prior art cargo tightener.
- U.S. Pat. No. 6,102,371 to Wyers, shows a strap tensioning and collection device having a variable length strap and a fixed length strap operatively associated with the strap storage section, and a strap tensioning section.
- U.S. Pat. No. 4,622,721 to Smetz, et al. shows a device for connecting components to a belt.
- German Offenlegungsschrift DE 36 39 712 A1 to Kinnert, shows a tensioning ratchet, in particular for belts, which is equipped with a ratchet body having a retaining bolt for fastening a safety belt, and having a ratchet lever which is mounted at the other end of the ratchet body so as to be rotatable about the axle of a slotted roller for fastening the end of a tensioning belt to be wound thereon.
- All of the above devices perform generally satisfactorily, but share the problem of relatively high costs and difficulty of manufacture. In addition, they are rather bulky. Thus, those skilled in the art continued their search for a better cargo tightener and strap collector.
- The aim of the present invention is to provide a cargo tightener and strap collector which is more cost effective compared with prior art devices, is less bulky, and is easier to manufacture. This is accomplished by having the strap collector on the lever portion of the cargo tightener, rather than on the connecting arm segment, as in the prior art. The advantages of this will become apparent by a careful reading of the detailed description, with appropriate reference to the accompanying drawings, wherein like numerals designate like parts in the several views.
- The invention is to be described in more detail below using exemplary embodiments.

FIG. 9 is an enlarged view, partly in section, of the construction shown inFIG. 7 , illustrating how the ratchet strap tail may be wound on the handle by turning the right hand knob, as long as the left hand knob has not been tightened. -
FIG. 10 is a view, similar in part toFIG. 9 , illustrating how the right hand knob can not be turned further once the left hand knob is tightened against the sidewall, thus securing the ratchet tail in place during transport of a load. - Referring to
FIG. 1 , there is shown a prior art cargo tightener and strap collector, generally designated by thenumeral 10. The cargo tightener andstrap collector 10 comprises a connecting arm or link 12, and a lever orarm 14. Astrap 15 is provided with ahook 16 at one end thereof for connection to a transportation vehicle (not shown). The other end ofstrap 15 is firmly held to connectingarm 12 bypin 17. Reciprocal motion oflever 14 usinghandle 18 will causeshaft 19 to rotate due to the ratchet andpawl assembly 13. - With reference to
FIG. 2 , there is shown the prior art cargo tightener andstrap collector 10 in a typical use situation, attached to acargo platform 11, usually of a movable type, and tightened about a load L to secure or tighten it in position. While the cargo platform is usually of the movable type, such as a trailer which may be pulled by a truck or tractor, cargo tightener andstrap collector 10 may also be used to secure stationary loads. - While
strap 15 causes no problem in the art, as when tightened on theload 11, it is always held taught by virtue of thehook 16 and thepin 17 when under tension, the same is not true ofsecond strap 15A.Second strap 15A has at one end asecond hook 16A attached tocargo platform 11. The other end ofsecond strap 15A is threaded through an opening orslot 19A inshaft 19, which is caused to rotate by reciprocal motion oflever 14 usinghandle 18. This will causeshaft 19 to rotate due to the ratchet andpawl assembly 13. While a portion ofsecond strap 15A intermediate its' ends will wind aroundshaft 19, a large portion ortail 15B will remain loose, and must be secured for safe transit ofload 13. - The securing of
ratchet strap tail 15B is a serious problem in the art as there is no readily available and cost effective place to store it. Usually the person placing theload 13 onplatform 16 will simply wind thetail 15B around a portion ofsecond strap 15A. Many times thetail 15B will be tied in a loose knot around thesecond strap 15A. No matter what solution is tried, thetail 15B frequently becomes loose during transit of theload 13 and flaps in the breeze as the load L is transported down the road, causing a hazard to surrounding drivers and pedestrians. Since many cargo tighteners are usually needed to secureload 13 toplatform 11,many tails 15B may be causing a hazard at the same time. - Referring to
FIG. 3 , the present invention relates to a modification of the prior art lever orarm 14 to solve the problems of the prior art. For purposes of understanding, new reference numerals are used when referring to the present invention. It can be seen that the improved cargo tightener andstrap collector 20 now provides for storage of the strap, now referred to by the numeral 50, on the arm orlever 24. There is provided a ready and secure place for storage of thetail 50A in the form ofroll 52, eliminating the problems of the prior art in a manner to be fully described hereinafter. - Referring now to
FIGS. 4-6 , the present invention relates to an improved cargo tightener and strap collector, generally designated by the numeral 20. An improved apparatus for tightening and collecting a strap, or strap collector, or combination cargo tightener andstrap collector 20, includes a connecting arm or link 22 and alever 24. Connectingarm 22 extends in a longitudinal direction, and may be substantially similar to the connectingarm 12 shown in the prior art construction ofFIG. 1 . It is a modification to the lever of the prior art construction, identified by the numeral 24, which provides a novel cargo tightener andstrap collector 20. As with the prior art, there is provided afirst shaft 26 journaled for rotation in one, or first,end 22A of the connectingarm 22. At the other, or second,end 22B of the connectingarm 22 is provided apin 23, to which a first, or short,strap 25 is attached. A first hook or fastening means orfastening device 27 is attached to the other end of thestrap 25. In use, thehook 27 will be attached to the transportation vehicle on which the cargo being tightened is being transported. - As in the prior art devices, reciprocal rotation of the
lever 24 will cause co-rotation of thefirst shaft 26. Journals forfirst shaft 26, as well assecond shaft 40, are provided by opposed apertures provided in a first pair of spaced apart sidewalls 36 provided in connectingarm 22, and a second pair of spaced apart sidewalls 37 in thelever 24. Asecond shaft 40 has provided therein second slot 42 (FIG. 4 ) to accept a free end, i.e., the end without thesecond hook 54, of asecond belt 50, as hereinafter described. - At least a first portion 40A of
shaft 40 may extend beyond at least one of the second pair of sidewalls 37 (FIG. 2 ) so that aknob 44 may be attached thereto for rotation of thesecond shaft 40. In the preferred embodiment, a first portion and a second portion (40A, 40B) of thesecond shaft 40 will extend beyond the second pair of spaced apart sidewalls 37, and aknob 44 will be attached to each portion of the second shaft. - Reciprocal rotation of the
lever 24 will cause co-rotational rotation of thefirst shaft 26 by virtue of a pair ofratchet wheels 60 which are mounted on thefirst shaft 26 between the first pair ofsidewalls 36 and the second pair of spaced apart sidewalls 37. It is preferred that tworatchet wheels 60 be used, although one may possibly be used.Pawl 61 aides in the rotation of thefirst shaft 26 by operating on theratchet wheel 60. Thepawl 61 is spring loaded and slides in a pair of opposed slots 64 (FIG. 4 ) in the second pair ofopposed sidewalls 37. - Second, or long,
strap 50 is provided havingsecond hook 54 provided at one end thereof. The free or non-active end ofstrap 50, so referred to because it has no connection tosecond hook 54, is first passed throughfirst slot 32 and then inserted in second slot 42 (FIG. 4 ).Second shaft 40 is then rotated, with the aid ofknobs 44, to roll up free end ofstrap 50 into aroll 52. - In use
second hook 54, andsecond strap 50, are completely unrolled and removed fromsecond shaft 40.Second hook 54 is attached to the transportation vehicle on which the cargo is to be transported, at the appropriate location. The free end of thestrap 50 is placed throughfirst slot 32 infirst shaft 26, and thelever 24 is reciprocally rotated, causing co-rotational movement of thefirst shaft 26. Since thefirst strap 50 is inserted in thefirst slot 32, and the connectingarm 22 is restrained by thefirst strap 25 and thefirst hook 27, the cargo tightener andstrap collector 20 is tightened down on the cargo. At this point, the free end of thesecond strap 50 is inserted in thesecond slot 42 in thesecond shaft 40 and theknobs 44 are rotated to take up any slack in the strap before the cargo is transported. - Alternately, the free end of the strap of the
second strap 50 may be left inserted in thesecond slot 42 in thesecond shaft 40, and thesecond strap 50 along withsecond hook 54 may be pulled out, causing theroll 52 to unwind until thesecond hook 54 may be attached to the transportation vehicle in the appropriate spot. Thelever 24 is then reciprocally rotated causing co-rotational movement of thefirst shaft 26, and the tightening of the cargo tightener andstrap collector 20 on the cargo (not shown) in the manner previously described. Any slack in thesecond strap 50 is taken up by rotating the knob orknobs 44 until the slack is removed. - In order to provide clearance for the
roll 52 so that it does not strike the cargo being transported, thelever 24 is provided with a first substantially linearly extendingportion 70, and a second linearly extendingportion 71 extending at an angle with respect to thefirst portion 70, thus elevating theroll 52 away from the cargo by elevating thesecond shaft 40 away from the cargo. - If it is desired to have the linearly and angularly extending
portions 71 of the second pair ofsidewalls 37 be further apart proximate theroll 52, a pair of divergingportions 72 of the second pair ofsidewalls 37 may be interposed between the first linearly extendingportion 70 and the second linearly and angularly extendingportion 71 of each of said second pair ofsidewalls 37. - Referring now to
FIGS. 7-10 , there is illustrated a modification of the present invention which locks theroll 52 positively in position on the arm orlever 24 of our cargo tightener and strap collector, now generally indicated by the numeral 55 for ease of understanding. This is accomplished by a modification toshaft 40 andknobs 44 described in regard toFIGS. 4-6 . In this modification of the invention, threadedshaft 80 is used in place of thesecond shaft 40. Threadedshaft 80 may be hollow, or at least partially hollow, and may have internal or external threads for the purposes described below. In the preferred embodiment, threadedshaft 80 is hollow, and has an aperture, opening, orhollow portion 82.Aperture 82 may include first portion or first threadedportion 84, and second portion or second threadedportion 86, of threadedshaft 80. Threadedshaft 80 will still haveslot 42 provided therein to receiveratchet tail 50A in the manner described above. - First threaded
portion 84 and second threadedportion 86 of threadedshaft 80 may be of the same or different diameters, as desired. It is preferable that the apertures in the second pair ofsidewalls 37 be slightly larger than the diameter of the adjacent threaded portions (84,86) of the threadedshaft 80 to accept a first threadedfastener 88 and a second threadedfastener 90. In the illustrated embodiment, the first threadedfastener 88 is of a smaller diameter than the second threadedfastener 90, so thefirst sidewall aperture 37A is of a smaller diameter that thesecond sidewall aperture 37B, and both are larger than their respective fasteners to allow free rotation of first threadedfastener 88 and a second threadedfastener 90 with respect to the associated aperture. - First threaded
fastener 88, which may be of any type well known in the art, is secured for non-rotation with respect to firstrotatable knob 92 by any known means. In other words, when firstrotatable knob 92 is rotated, first threadedfastener 88 rotates. First threadedfastener 88 is also fixed with regard to first threadedportion 84 of threadedshaft 80. Sincefirst sidewall aperture 37A is larger than first threadedfastener 88, and first threadedfastener 88 is fixed with regard to firstrotatable knob 92 and first threadedportion 84, when firstrotatable knob 92 is rotated, threadedshaft 80 will rotate as long as secondrotatable knob 94 is not tightened against asidewall 37. - Second threaded
fastener 90 is also fixed with regard to its' respective threaded portion (second threaded portion 86) ofaperture 82. However, secondrotatable knob 94 is not fixed with respect second threadedfastener 90 but, instead, is able to rotate with respect thereto because secondrotatable knob 94 has a threadedaperture 96 with threads complementary to those found on second threadedfastener 90. Thus, rotation of secondrotatable knob 94 will move it toward and away fromrespective sidewall 37. In operation, secondrotatable knob 94 is positioned in its loosened position, as shown inFIG. 9 . Ratchettail 50A is inserted inslot 42, and firstrotatable knob 92 is rotated, which rotates threadedshaft 80, which causesratchet tail 50A to be wound on threadedshaft 80 until it is wound up to formroll 52. At this point, secondrotatable knob 94 is rotated until it is tight againstsidewall 37, andsidewall 37 is tight againsthollow shaft 80, thus preventing any further rotation of the threadedshaft 80 by the firstrotatable knob 92. Since the free end of strap 50 (ratchet tail 50A) was inserted intoslot 42, and the remainder ofstrap 50 was wound on top ofratchet tail 50A before secondrotatable knob 94 was tightened, there is no loose portion of thestrap 50 to come undone and cause the dangers posed by the prior art cargo tighteners. - The scope of the present invention is not limited to the use of threaded fasteners and knobs, as any rotation mechanism by which the threaded
shaft 80 can be rotated, and then selectively be prevented from rotation, is well within the scope of the present invention. Many rotation mechanisms and/or rotation means are known in the art which are suitable for use in the present invention. - For example, the threaded
shaft 80 journaled for rotation between the second pair of spaced apart sidewalls 37 of thelever 24 may have a first threadedportion 84 to accept afirst rotation mechanism 98, and a second threadedportion 86 to accept asecond rotation mechanism 100. The first means ofrotation 98 is operable to rotate the threadedshaft 80, and the second means ofrotation 100 is operable to restrain or permit rotation of the threadedshaft 80. The use of any motion transfer means whereby rotary motion is transformed into axial motion is well within the skill of the art. - Thus, by carefully considering the problems in the prior art devices, we have provided a novel cargo tightener and strap collector which is simpler in construction, easier to manufacture and less costly than prior art devices.
