A weight attachment 1 according to a first example, shown in a closed condition in Figure 1 and an open condition in Figure 2, ses a generally spherical, semi-hardened rubber body 3 comprising opposed generally hemispherical first and second sections 3A, 3B. The attachment 1 further comprises a hinge 12 which is secured to opposed faces of the sections 3A, 3B, thereby pivotally onnecting those sections such that they are pivotally moveable between the closed condition and the open condition. The hinge 12 is an inverted butt hinge, comprising pivotally interconnected plates 12A, 12B, which are received in recesses formed into the sections 3A, 3B respectively, so as to be countersunk, and which are secured to the ns 3A, 3B via . The hinge 12 is provided with a nal spring 14 which acts to spread the plates 12A, 12B apart and thus exerts an opening bias on the sections 3A, 3B. Proximal ends of the ns 3A, 3B are formed with chamfers 5A, 5B respectively, which define a relief rearward of the hinge 12, permitting the attachment 1 to open, and which abut each other when the attachment 1 is fully open to preclude r opening. ing to Figures 3 and 4, the ment 1 is designed to clamp to a free end of a strap 50 so as to provide weight to that end and facilitate throwing of the end over a load to effect receipt of the strap 50 around the load to tie it down (see Figures 7A and 7B). So that the attachment 1 will reliably grip the strap 50, the sections 3A, 3B are provided with opposing gripping portions 16A, 16B respectively which, when the attachment 3 is closed over strap 50, engage the strap 50 and preclude movement of the ment 1 along the strap 50.

The gripping portions 16A, 16B comprise opposed serrations which interengage when the attachment 1 is closed so as to bite the strap 50, the serrations extending perpendicular to the pivot axis of the hinge 12. In another example, the gripping portions may differ; for example, they may comprise generally flat but coarse opposing surfaces, so as to have sandpaper-like finishes and thus be frictionally engageable with the strap 50. The gripping portions may be defined by separate elements (e.g. metal plate elements) which are attached to the sections 3A, 3B or may instead be integral parts of those sections and formed when the sections are moulded.

Referring to Figures 3, 8A and 8B, the ment 1 is also designed so as instead to hold a metal triangular eye 57 coupled to the strap free end. For this purpose, the portion 3B is formed with a notch 17 which is v-shaped so as to have a profile complementary to a g portion of the eye 57, whereby that portion fits snugly in the notch 17, such that, when the ment 1 is then closed (in the aforementioned manner), the eye 57 and attachment 1 are interlocked. The notch 17 may be sufficiently shallow that the eye 57 is clamped between the ns 3A and 3B when the attachment 1 is closed. Alternatively, the notch 17 may be sufficiently deep that, when the attachment 1 is closed, it does not clamp the eye 57 but nevertheless engages it in the manner of a clasp.

The attachment 1 further includes a locking pin 20 for holding the body 3 closed. Referring in particular to Figures 5, 6A and 6B, the pin 20 extends through a passage 18A formed through a distal end of the section 3A such that a leading end 22 thereof projects from the section 3A, perpendicular to the gripping n 16A, to be receivable in a passage 18B formed in the section 3B when the sections 3A and 3B are brought er. The pin 20 comprises a head 24 at a trailing end f, which is ned within a cavity 30 formed into the exterior of the section 3A so as to be recessed relative to the curved surface of the n 3A and thus shielded from impact against any object when the attachment 1 has been thrown. The head 24 is sized so as to preclude the trailing end from being drawn through the passage 18A. The pin 20 comprises a sleeve 25, a shaft or plunger 26 received in the sleeve, and ball bearings 27 ed by the sleeve 25 and positioned nt respective circumferentially spaced apart openings 28 formed through a wall of the sleeve at the pin leading end. The shaft 26 is le in the sleeve 25 between a first position, shown in Figure 6A, in which it urges the ball gs radially outwardly such that portions thereof project from the sleeve wall, and a second position, shown in Figure 6B, in which a circumferential groove 29 in the shaft 26 is brought into ent with the openings 28 so as to be able to receive radially inner portions of the ball bearings 27 and thus permitting retraction of the ball bearings 27 such that they are fully contained in the sleeve 25. The pin incorporates a spring 23 which biases the shaft to its first position. The spring 23 is received in an annular recess defined between a narrowed section 44 of the shaft 26 and the circumferential wall of the sleeve 25 and is compressed between an underside of a trailing end 21 of the shaft and an annular shoulder 42 which projects radially inwardly from the sleeve circumferential wall. The er 42 is arranged to abut a ponding shoulder formed on the shaft 26 at a lower end of the narrowed section 44 when the shaft 26 is in its first position, thereby retaining the shaft 26 in the sleeve 25. The trailing end 21 of the shaft 26 projects axially from the head to be - or thumb-depressible, against the spring bias, for moving the shaft into its second position.

A ferential groove 32 is formed into the wall of the passage 18B and arranged to receive radially outer portions of the ball bearings 27 when the body 3 is closed and the pin 20 is received by the passages 18A and 18B with the shaft in its first position, thereby locking the pin leading end to the section 3B such that the body is held closed against the bias of the spring 14.

Alternative uses of the ment 1 in securing a load for transportation by a vehicle will now be bed.

In one mode of use, referring to Figure 3, the attachment 1 in the open condition is introduced ys over the strap 50 at a free end thereof. Advantageously, owing to the attachment's being sideways ucible over the strap 50, its being coupled to the strap 50 is not obstructed by a hook 55 or other fitting attached at the tip of the strap. With the shaft pressed into its second position by a finger or thumb, the sections 3A and 3B are then pushed, against the bias of the spring 14, such that the gripping portions 16A, 16B clamp against the opposed faces of the strap 50 and the leading end of the pin 20 is received into the passage 18B. The finger or thumb pressure against the shaft trailing end is then discontinued, whereupon the shaft s to its first position, so as to urge the ball bearings 27 radially outwardly and effect receipt of the radially outer portions thereof in the circumferential groove 32 and thus interlocking between the pin 20 and section 3B. Referring to Figures 7A and 7B, the attachment 1, thus now securely fixed to the strap 50 can then be used to introduce the strap 50 over a load 70 supported on a bed 80 of a vehicle. Specifically, a person ng at one lateral side of the bed 80 throws the attachment 1 over the load 70 such that it carries or draws the strap 50 over and around the top of the load 70. Preferably, the end of the strap 50 which is opposite to that at which the attachment 1 is secured is d to the side of the bed 80 at which the person stands, e.g. by being wrapped around a rail 82 at that side and/or via another hook er fitting, before the person throws the attachment 1 over the load 70, whereby that opposite end is anchored and reliably precluded from being carried over the load 70 when the attachment 1 is thrown. The end of the strap 50 at which the fitting 1 is attached can then be coupled to the bed at the opposite side thereof, e.g. by attaching the hook 55 at that end to a rail 82 at the opposite side. If riate, the strap 50 may then be tensioned, e.g. by means of a ratchet device (not shown) applied to the strap 50 (e.g. defining the aforementioned “other fitting”), as known to a person skilled in the art.

In the other mode of use, referring to Figures 8A and 8B, the attachment 1 is attached to the eye 57 d to the strap free end. With the shaft pressed into its second position by a finger or thumb, the sections 3A and 3B are then pushed, t the bias of the spring 14, such that the portions 3A and 3B clamp or clasp the eye 57, as usly described, and the leading end of the pin 20 is received into the passage 18B. The finger or thumb pressure against the shaft trailing end is then discontinued, in the manner previously bed, whereby the interlock between the pin 20 and section 3B, and thus closure of the attachment 1 over the eye 57, is effected. The attachment 1, thus secured to the eye 57, can then be thrown to introduce the strap 50 over the load 70 in substantially the same manner as shown in Figure 7A, and thereafter removed from the eye 57 whereby the eye 57 can, if appropriate, be used to anchor the strap end. Advantageously, owing to much of the eye 57 being enclosed by the attachment 1 when it is attached thereto, the attachment 1 can serve as a protective shield y objects struck as a result of the ng the attachment 1/strap end are impacted by the attachment 1, which is relatively soft, instead of by the eye 57, which is hard. Also ageous is that, in this mode of use, the attachment 1 is received at/over the leading end of the assembly comprising the strap 50 and eye 57, which leading end is defined by the eye 57, whereby throwing and good carriage of the attachment 1/strap end are facilitated.

Shown in Figures 9A and 9B, in open and closed conditions respectively, is a weight attachment 1' according to a second example. In the description and s of this embodiment, the same reference numerals as have been used in respect of the first example are used to denote and refer to the same or corresponding features.

The attachment 1' is identical to the attachment 1 except with respect to the means for holding the body 3 closed and the configuration of opposed faces of the attachment 1 which mate when the attachment 1' is closed, as discussed further below.

The means for holding the attachment 1' closed comp rises a clasp 40 comprising a transversely extending locking pin 42 opposite ends of which are held within the section 3B, the pin 42 extending within and traversing a cavity or recess 43 formed within the portion 3B.

The clasp 40 further ses a link 44 and a mounting pin 45 via which the link 44 is pivotally mounted to the section 3A and extends within and traverses a cavity or recess 46 formed within the section 3A, opposed ends of the pin 45 being held within the n 3A.

Owing to the ion of the recesses 43, 46, the clasp 40, when closed, is countersunk with respect to the curved outer surface of the attachment 1'. The link 44 is ured with a resiliently deformable catch 47 which, when the attachment 1' is closed, can be interlockingly ed over the pin 42, whereby the clamp 40 is closed and the device 1' is thus locked in its closed ion. The clasp 40 can be opened simply by pulling the distal end of the link 44 in a direction away from the pin 42, thereby effecting resilient deformation of the catch 47 and thus release of the link 44 from the pin 42.

In the attachment 1', each of the ns 3A, 3B is configured with a notch 17, the notches 17 being arranged so as to marry up to hold the eye 57 when the attachment 1' is closed.

In the present example, the sections 3A, 3B are not provided with gripping portions comprising opposed serrations/corrugations or having coarse opposing surfaces, though may be so provided whereby gripping of a strap 50 may be enhanced.

The attachment 1' may be attached to the strap 50 or eye 57 in the same manner as the attachment 1.

It will be appreciated that the notch(es) 17 in the examples described and illustrated may d be configured to fit to an ative fitting, such as a hook member 55 or 55’, coupled to the strap end.

The hinge in each of the attachments 1 and 1' may be replaced with an alternative hinge, such as a le hinge, e.g. a living hinge or a hinge which is defined by a section of strap which is secured to the first and second sections, e.g. against outer faces thereof via screws, and/or which may be inset.

Shown in Figures 10 and 11A to 11E is a weight attachment 1’’ ing to a preferred embodiment of the present invention. In the description and figures of this ment, the same reference numerals as have been used in respect of the first and second examples are used to denote and refer to the same or corresponding es.

The attachment 1’’, like each of the attachments 1 and 1’, comprises a generally spherical semi-hardened rubber body 3. The body 3 in this ment, however, does not comprise pivotally interconnected hemispherical sections; rather, it is of single-piece, “unopenable”, construction. The attachment 1’’, like each of the attachments 1 and 1’, is removably attachable to the triangular eye 57, the latter when in use being coupled to the free end of the strap 50 as shown in Figures 8A and 8B, so as to provide weight to that end to facilitate throwing of the end over a load, y to effect receipt of the strap 50 around the load to tie it down in a manner tent with what is shown at Figures 7A and 7B. The attachment 1’’ includes a locking mechanism, in the form of a conventional rotary latch mechanism 60, which is a well-known component, that is anchored within the body 3 and arranged within a recess 4 formed in the body 3, so as to be countersunk in the body 3, whereby it does not upset the namics of the attachment 1’’ and is ed from impact against s when the attachment 1’’ has been thrown. As will be clear from Figure 10, the rotary latch mechanism 60 is engageable with the leading end of the eye 57 when the latter is inserted in the recess 4. The mechanism 60, referring to Figures 11A and 11B (which show the mechanism 60 in a closed condition, and not in engagement with the eye 57), comprises a bracket 61, which is anchored within the body 3 so as to be fixed relative thereto, the bracket 61 having opposed sidewalls 62 configured with transversely aligned ly outwardly opening slots 63, and a latch, defined by an element 64, arranged between the sidewalls 62 and pivotally attached to them. A distal end of the element 64 is configured with spaced apart projections 65 which define a slot 66 that opens radially outwardly with respect to the pivot axis of the element 64, the outermost one of the projections 65 being configured with a curved distal end 65A. As can best be seen at Figure 11B, when the mechanism 60 is in a closed condition, the slot 66 is arranged between and in alignment with the slots 63. The mechanism 60 includes a torsional spring 67 comprising a helical coil one end of which is fixed relative to the bracket 61 and the other end of which is fixed relative to the element 64, the spring 67 being ed to bias the element towards the open position shown in Figure 11C. The mechanism 60 further comprises a trip lever 81, arranged between the sidewalls 62 and pivotally attached to them, and a torsional spring 82 sing a helical coil one end of which is fixed relative to the bracket 61 and the other end of which is fixed relative to the element lever 81 such that, when the lever 81 is pivoted in either rotational ion from the position shown in Figure 11B, the spring 82 exerts on lever 81 a biasing torque towards that position. A portion (not shown) of the lever 81 which is forward of that lever’s pivot point is configured to engage catch (not shown) formed a portion of the element 64 which is rearward of that element’s pivot point, such that the lever 81 locks the element 64 in the closed position shown in Figure 11B. The mechanism 60 further comprises a lever 68 which is pivotally connected, via a fastener 69, to the bracket 61, the lever 68 comprising a thumb-engageable portion 68A, which projects radially outwardly from the rotational axis of the lever 68, and a projection 68B, which projects radially dly from that axis in the opposite direction so as to abut a projection or tab 81A formed on the trip lever 81 at a position which is rearward of that lever’s pivot point, such that application of thumb re to the portion 68A, in the direction of arrow A shown in Figure 11B, induces ng of the lever 81, against torsional resistance offered by the spring 82, into the position shown in Figure 11C, whereby the aforementioned portion of the lever 81 is disengaged from the catch of the element 64 and the element thus pivots into its open position, the mechanism 60 thus assuming an open condition. The bracket 62 is configured with a stopper 62A, in the form of a tab integrally formed with one of the sidewalls 62, which is arranged to abut the element 64 so as to preclude pivoting thereof beyond the on shown in Figure 11C. The recess 4, as will be clear from Figure 10, is iently large to permit thumb access for the purposes of ing the lever 68. The element 64 can be returned to its closed position by pressing the forward end thereof towards the body 3 r by hand or with the leading end of the eye 57, if the latter is being brought into engagement with the mechanism 64 when open), whereby the element pivots back to its closed position, the rearward portion of the element 64, as that element does so, riding over the d portion of the lever 81 and in so doing pivotally displacing it, whereby the lever 81 reverts to the position shown in Figure 11B and engagement between the d n of the lever 81 and the catch is re-established.

To effect interengagement of the eye 57 and mechanism 60 when the latter is closed, a person inserts the eye leading end into the recess 4 such that it abuts the outermost projection 65, thereby causing the element 64 to pivot, out of engagement with the trip lever 81 (which remains in the position shown in Figure 11B) and against nal resistance offered by the spring 67, y the projections 65 are rotationally displaced further into the body 3 and the eye leading end is received in the slots 63. Upon the element 64 being rotationally displaced to a sufficient degree, the tip of the eye leading end slides, over the curved end 65A, past that end, whereupon the resilient bias returns the element 64 to the position shown in Figure 11B and the tip is received in the slot 66. The ism 60 is thus it engageable with the eye 57.

The slot is dimensioned such that the resulting fit formed between the tip and slot 66 is snug.

The eye 57 and attachment 1’’ are thus interconnected, as shown in Figure 10. To release the eye 57 from the attachment 1’’, the ism 60 is placed into its open condition, in the manner previously described with reference to Figures 11B and 11C, permitting the eye 57 to be withdrawn from the element 64.

The mechanism 60 is a rotary latch having model no. R43210 and produced by Southco. Details of the latch are at http://www.southco.com/en-us/r4-r/r41010 .

The mechanism has right-hand actuation, as will be clear from Figures 11B to 11D, though may instead have left-hand actuation if the user of the attachment is left-handed, rather than right-handed.

The locking ism may se a different type of rotary latch, or something other than a rotary latch, without departure from the invention.

Referring to Figure 11E, the body 3 is configured with a seat portion 3A, comprising a flattened area, at a side thereof opposite said mechanism 60, the seat portion being receivable against a surface whereby the ment 1” is stably ted on the surface in a position such that mechanism 60 is uppermost.

The ment 1’’ may, without departure from the invention, be modified such that, when the eye 57 is engaged therewith, the plane in which the triangle defined by the eye lies passes through the centre of mass of the body 3 or ment 1’’, which centre of mass is substantially coincident with the geometrical centre of the sphere defined by the body 3, and the locking mechanism is anchored to the body 3 in a manner permitting the body 3 to swivel relative to the locking mechanism 60 about an axis lying within the plane and passing through the aforementioned centre of mass/geometrical centre. As a result, rotation about that axis, imparted to the attachment 1’’ at the the time it is thrown, will not be, in turn, imparted to the eye 57, y twisting of the strap 50 as it is carried over the load by the attachment 11’’, is restricted or eliminated.

Each of the attachments 1, 1' and 1” is of a weight which is iently low to permit it to be thrown over the load 70 yet sufficiently high to provide enough mass at the strap end to carry it reliably over the load, ularly in windy ions which would otherwise hinder the strap end from being so carried under its own weight. Each of the attachments 1, 1’ and 1”, in being spherical (at least when in situ) is aerodynamic and, in comprising a rubber body is sufficiently soft such that a risk of damage to the vehicle or another object, as a result of its being thrown, is d or eliminated.

While various ments of the present invention have been described above, it should be understood that they have been ted by way of example only, and not by way of limitation. It will be apparent to a person skilled in the relevant art that various s in form and detail can be made therein without departing from the spirit and scope of the invention. Thus, the present invention should not be limited by any of the above described exemplary embodiments.

Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
