RATCLIFF OVER-CENTER LOAD BINDER v 3 Sheets-Sheet 5 Filed Jan. 6, 1965 United States Patent 3,271,007 OVER-CENTER LOAD BINDER Ralph A. Ratclilf, 1300 Sunnyslope Ave, Belmont, Calif. Filed Jan. 6, 1965, Ser. No. 423,733 14 Claims. (Cl. 254-78) This invention relates generally to a load sustaining or tensioning device. More particularly, this invention relates to an improved over-center or toggle type load binder intended, among other uses, to bridge the gap between holddown elements positioned around a load on a supporting platform and to apply tension to such holddown elements to preclude the load from shifting.

Still more particularly, this invention relates to a light weight, portable, heavy duty over-center load binder which is extremely compact in construction so that the same may be conveniently employed in close quarters for binding loads of various types, sizes and contours. In this connection, the subject load binder is simple in construction and includes only three principal components, two of which are specifically formed to accommodate holddown elements directly therein without bending, twisting or otherwise deforming the holddown elements.

While reference herein is directed to the subject invention employed for holding a load on a supporting surface, it should of course be understood that its use in other binding or tensioning arrangements for which load binders heretofore or hereafter may be commonly employed also is contemplated. The embodiment disclosed herein is shown in conjunction with securing a given load, such as a plurality of logs, on a transportation vehicle, such as the cradle carriage or platform bed of a logging truck, and the binder is well suited for such usage. The compact construction of the subject binder makes it particularly well suited for use in positions having little access room in which heretofore known bulky binders could be employed only with difiiculty, if at all.

The subject binder consists of only three principal operating components, namely a manually graspable operating lever and two compact hook members pivotally connected with the operating lever. It is with the respective hook members that the holddown elements to be tensioned about a load by the load binder are directly engageable. Prior known and commonly employed grab hooks and swivels are omitted completely with the subject binder.

In broad function, the subject binder operates in the same manner as do known over-center load binders. That is, the normal distance between the hook members, when the binder is in its open position, is shortened by moving the operating lever past a dead center position to a closed position in which it generally overlies one of the book elements. Such movement of the lever draws the two hook members generally towards each other to thereby draw ends of the holddown elements similarly towards each other to apply tension thereto.

The subject binder, however, has a very important distinction and advantage over known over-center binders in that it includes means in conjunction therewith to latch selectively together one of the hook members and the operating lever so that, upon unbinding, the hook member is forced to travel with the operating lever until the holddown element engaged by the hook member is released. This results in generally constant force being maintained on the operating lever during unbinding so that the lever cannot fly unrestrained during unbinding. It is such unrestrained flying of the operating lever, characteristic of known over-center binders, which frequently results in injury to persons unbinding known binders.

With the subject load binder, during the unbinding operation the load or force on the lever is maintained generally constant due to continued application of tension on "ice both holddown elements engaged therewith which is insured by the enforced movement of one hook member with the operating lever. Thus, the operating lever is preeluded from passing over the dead center position relative to that hook member and any tendency of the lever to fly out of the operators hands is obviated. That is, the latching means of this invention insures that one of the hook members travels with the operating lever until that book member reaches a position in which the holddown element engaged therewith is freed. Thus, the possibility of the load on the lever being abruptly released is pre eluded and therefore the danger of the lever flying unrestrained is also precluded.

The subject load binder has another important advantage, namely that the hook members employed therewith require no separate swivels and grab hooks which can imci fically to receive chain links therein in straight line straddling relationship without deforming, twisting or otherwise undesirably stressing the links. Thus, a problem encountered with prior over-center binders which tend to turn sideways against the load being secured, due to the twisting effect of the holddown elements, is obviated.

The subject load binder has the fiurther important advantage that it includes means in its construction for positively and automatically locking the operating lever in the closed load binding position. Such automatic locking means positively holds the operating lever locked until manually released whenunbinding is desired. This automatic locking capability not only precludes the danger of the operating lever being accidentally jostled to the open position during transportation, but also minimizes the danger of vandals or other unauthorized persons intentionally releasing theload.

From the foregoing it should be understood that objects of this invention include the provision of a load binding device which is extremely compact, sturdy and highly reliable; the provision of such a device which includes only three principal components and which obviates the need for known swivels and grab hooks in conjunction with the operating lever thereof; the provision of such a device which includes means to preclude the possibility of the operating lever flying unrestrained during an unbinding operation; the provision of a device which includes means to positively lock the operating lever in the closed load binding provision; and the provision of a device which overcomes any tendency to turn sideways when in use. These and other objects will become evident from the following description in which reference is directed to the accompanying drawings for a further understanding of the invention.

FIG. 1 illustrates generally schematically a plurality of the subject load binders employed tobind a load of logs on a transporting vehicle, such as a logging trailer.

FIG. 2 is a side elevational view of the subject binder in the open position showing holddown elements engaged with the hook members thereof.

FIG. 3 is a rear elevational view of the subject binder with one of the holddown elements omitted therefrom for purpose-s of clarity of illustration.

FIG. 4 is a partial side elevational view of the subject binder closed and locked in the load binding position.

FIG. 5 is a rear elevational view of the closed and locked binder of FIG. 4.

FIG. 6 is a cut away partial side elevational view of the subject binder which illustrates enforced movement of one hook member with the operating lever as the operating lever is moved from the closed position to the open position during an unbinding operation. This figure shows the respective components of the binder located in the positions which they take just prior to release of a load holddown element by said one hook member.

FIG. 7 is a rear elevational view of the binder components in the position shown in FIG. 6, with the holddown elements omitted for purposes of clarity of illustration.

FIG. 8 is a sectional view taken in the plane of line 88 of FIG. illustrating on an enlarged scale details of the automatic locking means for holding the operating lever in the closed position.

FIGS. 9 and are sectional views taken in the planes of line 9-9 and 1010 respectively of FIG. 8 illus trating details of the latching means which insures travel of one hook member with the operating lever.

Before describing details of the subject over-center load binder, reference is directed to FIG. 1 which shows a plurality of the subject binders, each generally designated 1, exemplarily employed in binding a load in place. In the logging industry, for example, it is common to pile a plurality of freshly cut logs on the cradle platform or flatbed of a trailer chassis to be pulled by a truck or tractor. A suitable supporting platform, defined by spaced cradles 2 located above the wheels 3 of a trailer in known fashion, is illustrated in FIG. 1 and it is upon such a cradle platform that a plurality of logs 4 are stacked in known fashion.

A series of pairs of holddown elements 6 and 7 extend around the load at spaced locations therealong. It is between the adjacent

free ends

8 and 9 of these holddown elements that the subject load binders are operatively interposed to bridge the gap between the holddown element ends and to apply tension to the holddown elements when a binder operating lever is moved to its closed position. In some instances ends 8 and 9 of the holddown elements may be part of one continuous element passed completely around the load. In many cases, however, the respective holddown elements 6 and 7 are two discrete elements secured to the transporting vehicle at opposed locations in any suitable and well known manner. In either event, connecting together and applying tension to the

adjacent ends

8 and 9 of the respective holddown elements will secure the load against shifting during movement.

The illustrated holddown elements are defined by lengths of flexible wire cable which have, at their

ends

8 and 9, lengths of coil chain secured thereto. Of course, the holddown elements may be, and frequently are, defined entirely by coil chain links for their full lengths.

The subject over-center load binder is defined by only three principal operating components, and heretofore used grab hooks and swivels are not included in its construction. Referring to FIGS. 2 and 3, the binder comprises .an elongated operating lever 12 which is movable between a load releasing open position and the aforementioned load binding closed position. The other two components of the subject binder comprise a first or bottom hook member 13 and a second or top hook member 14.

The operating lever has at one end 16 thereof a manually graspable handle portion and at its other end 17 a clevis portion defined by a pair of laterally spaced

arms

18 and 19 joined with each other and with the handle portion at a location 20 generally intermediate opposite ends of the lever as perhaps best seen in FIG. 3. To minimize weight without restricting strength of the operating lever, through the major extent of its handle portion and into and through its clevis portion, the lever is formed with a recessed channel construction.

Each of the

clevis arms

18 and 19 includes an offset eccentric portion 21 which imparts a generally dog leg configuration to the lever as seen in FIG. 2. It is such an offset dog leg configuration, characteristic of this and other over-center load binders, which permits such a binder to operate in toggle fashion to draw holddown elements engaged therewith towards each other for applying tension thereto.

Bottom hook member 13 is generally U-shaped and is defined by a pair of laterally spaced

arms

22 and 23, which are provided with reinforcing

ribs

24 and 26 extending t-herealong, as seen in FIGS. 2 and 3. Hook member 13 is pivotally connected adjacent the end of the operating lever clevis in straddling relationship with respect to the

arms

18 and 19 thereof by means of a pair of

stub pivot shafts

27 and 28 integral with and projecting outwardly from the clevis arms into appropriate bores provided in the hook member arms. Thus hook member 13 is securely yet pivotally connected with the operating lever. As is described in greater detail later, the free end of hook member 13 is defined by a portion thereof specifically contoured to receive directly therein links of a chain holddown element. The top hook member 14 also is generally U-shaped and is also pivotally connected with the operating lever. In this regard, the offset portions 21 of the

clevis arms

18 and 19 are aperturedto receive therein a pivot pin 31 extending transversely therebetween. It is upon pin 31 that hook 14 is pivotally mounted between the arms of the clevis portion. As seen in FIGS. 2 and 3, hook member \14 may pivot through a complete circle between the arms of the lever clevis portion and the arms of book member 13. As is also seen in FIG. 3, pivot pin 31 upon which hook member 14 is mounted is precluded from lateral movement by a pair of split rings 32 received in appropriate grooves provided in the pin. Hook member 14 also has at its free end a portion specifically contoured to receive directly therein links of a chain holddown element.

Each of

hook members

13 and 14 is of rigid one piece construction and each is provided with an integral chain receiving recess formed directly therein. The chain receiving recess of bottom hook member 13 is generally designated 33 while the chain receiving recess of top hook member 14 is generally designated 34. Those chain receiving recesses are substantially identical in configuration and hereinafter reference is directed specifically to recess 33 of the bottom hook member 13 but such reference is equally applicable to recess 34 in the top hook member.

Such recess is defined by a pair of angularly related communicating channel portions 35 and 36 (see FIGS. 3 and 7) each of which extends generally longitudinally of the hook member. The respective channel portions are arranged generally at relative to each other to receive therein two adjacent links of coil chain to be engaged thereby. In this regard, note FIGS. 2 and 3. Thus, tension is applied by each hook member substantially directly in line with the axis of the coil chain so that no twisting, bending or other distorting stresses are applied to the chain links. That is, the respective hook members straddle the chain links engaged therewith without twisting the same in the fashion heretofore commonly encountered with load binders employing grab hooks and swivel arrange- .ments of known type.

It is this straddle engagement of the hook members of the subject binder with chain links of the holddown elements which obviates the problem encountered with heretofore known over-center load binders to twist or turn sideways when engaged with a load. Such sideways turning in heretofore known binders is attributable to the twisting moments applied to the holddown elements by the grab hooks and swivel arrangements commonly employed therewith. If over-center binders turn sideways when in the closed position, it is frequently difiicult and sometimes impossible to grasp their operating levers to release the same during a load unbinding operation. However, referring to FIG. 1, with the subject device in which such tendency to twist and turn sideways is obviated, the operating lever thereof is readily accessible for ease of unbinding.

While in the drawings the last two links of chain holddown elements have been shown engaged with the respective hook members of the binder, it should be understood,

of course, that any chain links intermediate the ends thereof also may be easily engaged by the hook members. Any excess chain links encountered may merely be positioned to one side or folded back out of the way of the operating parts when the binder is utilized.

The latching means which precludes the operating lever from flying without restriction when the binder is moved from the closed position (FIGS. 4 and 5) back to the open position (FIGS. 2 and 3) generally comprises spring urged mechanism carried by the top hook member 1 4. Such spring urged mechanism is automatically engageable with a predetermined portion of the operating lever when the lever is moved to its closed position. In this regard, the illustrated latching means includes spring urged mechanism defined by at least one and preferably tw-o latching pins 40, perhaps best seen in FIGS. 3, 4, 5 and 9. These latching pins are carried by top hook member 14 in recesses provided in

opposite arms

41 and 42 thereof (see FIG. 9). Latching pins 40 normally project laterally outwardly beyond

arms

41 and 42 as shown in FIGS. 5 and 9 and their outward travel is limited by enlarged collars 43 provided thereon. In the illustrated embodiment a coil spring 44 is interposed between the respective pins and urges the same laterally outwardly to the normal position shown in FIGS. 5 and 9.

The latching pins, when the binder is positioned to receive holddown elements prior to binding thereof, are held depressed between the spaced arms .18 and 19 of the clevis portion of the operating lever as shown in FIGS. 2 and 3. To this end, each of the arms of the clevis portion is provided on its internal surface with an arcuate rib 4 6 over which the respective latching pins ride during relative pivotal movement between the top hook member 14 and the operating lever.

It should be understood that the latching pins, when the operating lever is moved to its closed position, engage a predetermined position of the operating lever to thereafter preclude movement of the operating handle without producing attendant movement of the top hook member 14 therewith. That is, when the operating lever is moved from the open position shown in FIG. 2 to the closed position shown in FIGS. 4 and 8, the latching pins 40 ride on the arcuate ribs 46 until they reach the ends of those ribs, at which time they are spring urged outwardly into engagement with edge portions of the

respective arms

18 and 19 of the clevis portion of the operating lever. This position of the latching pins relative to the clevis arms is best shown in FIGS. 4, 5 :and 9. When the latching pins are thus engaged with the outer edge portions of the clevis arms, movement of the operating lever from the closed position shown in FIG. 4, for example, towards the open position automatically and necessarily produces attendant movement of the top hook member 14 therewith. This condtion is shown for example in FIGS. 6 and 7.

In this regard, the showing in FIG. 6 illustrates generally the relative position of the top hook member 14 and operating lever relative to the bottom hook member 13 at the time when the coil chain links which define the end of the holddown element are about to be released by the top hook member. Up until the actual moment of release, however, due to the enforced movement of the top hook member with the operating lever, the force applied to the lever by the operator in unbinding the load has remained generally constant and the tendency of the lever to fly out of the operators hands has been obviated in that the lever does not move past the dead center position relative to the top hook 14 during unbinding. Thus, while in practical effect the subject load binder, during unbinding, releases the chain holddown element relatively abruptly, that condition is preferred over abrupt flying of the operating lever.

The binder includes a further improvement in conjunction with the latching means which permits the top hook member 14, after load release, to be easily posi- 6 tioned in the operative location shown in FIG. 2 for again binding a load. Referring to FIGS. 8, 9 and 10, each of the arms of the lever clevis portion includes a deflecting ear 47 which extends laterally outwardly relative to an associated arm. The deflecting ears diverge relative to each other as seen in FIG. 10. Such deflecting ears are positioned at one end of the arcuate ribs46 in line with the latching pins 40 when the top hook member 14 is pivoted, following disengagement of chain 8, in the clockwise direction from the position viewed in FIG. 6. Thus, when the latching pins reach and strike the deflecting ears, the pins are automatically depressed inwardly of hook member 14. Upon continued pivotal movement of hook member 14, the latching pins ride over the arcuate ribs 46 provided on the respective arms of the clevis portion of the lever. Thus, it is readily possible, by moving the hook member 14 in a clockwise direction when viewed in FIGS. 2 and 6, to automatically reposition the hook member 14 for reengagement with links of a holddown element. The circular path through which latching pins 40 may pass relative to the operating lever and the deflecting ears 47 carried thereby as hook member 14 is pivoted is shown by the dot-dash line in FIG. 8.

The subject load binder further includes means for locking the operating lever in the closed position shown in FIGS. 4 and 8 in which it generally overlies the bottom hook member 13. Such locking means is manually releasable to permit unbinding of the load as required. In the embodiment illustrated, the locking means comprises a spring urged movable trigger 50 extending transversely of bottom hook member between the opposed arms thereof. Trigger 50 at one of its ends 51 is loosely received in a bore 52 provided in arm 22 of the hook member; At its opposite end 53, trigger 50 extends through an elongated slot 54 in the opposite arm 23 of hook member 13. A split ring 56 is engaged with end 51 of the trigger and precludes movement thereof to the right as seen in FIG. 3. A projecting pin and

spring assembly

57, 58 precludes movement of the trigger to the left as viewed in FIG. 3.

Pin 57 is fixedly secured in the trigger and extends therefrom through a slot 59 (FIG. 3) provided in a projecting flange 61 which extends laterally of arm 23 of hook member 13. A similar flange 62 is spaced from flange 61 and cooperates therewith in protecting the depressible end 53 of the trigger during use of the load binder.

As shown in FIG. 5, when trigger 50 is depressed by urging end 53 thereof toward flange 61 against the urging of spring 58, the trigger may move within slot 54 to the dotted line position shown in FIG. 5. It is when the trigger is in that depressed position that the operating lever of the binder may be released from its closed and locked position.

Cooperating with the trigger is a locking ear 61 formed on and projecting from arm 19 of the clevis portion of the operating lever. As best seen in FIG. 8, when the operating lever is moved to the fully closed position, trigger 50 rides over locking car 61 and automatically snaps into engagement therebehind. Thus, when the trigger and locking ear 61 are engaged as shown in FIG. 8, clockwise movement of the lever from the closed position shown in that figure towards the open position is positively precluded. However, upon depressing movable end 53 of the trigger, disengagement of the locking car from the trigger may be easily effected and the operating lever is then free to be moved toward the open position to permit load unbinding.

The locking means thus insures positive locking and precludes accidental unbinding of a load secured by the subject binder while incorporating those advantages in a readily accessible and easily operable locking mechanism.

Having thus made a full disclosure of this invention reference is directed to the appended claims for the scope of protection to be afforded thereto.
