This patent application claims priority from: Australian Provisional Patent Application No. 2012901884, titled “A SUPPORT ARRANGEMENT FOR AN IMPLEMENT”, and filed on May 9, 2012. The entire content of this application is hereby incorporated by reference.
FIELD OF THE INVENTIONFor the purpose of explanation this invention will be described in relation to metal detectors, although the invention is not so limited in application.
Various applications of metal detectors involve prolonged periods of use where the load associated with the weight of a metal detector unit is carried by an upper arm, shoulder and upper back of a user, often resulting in fatigue and discomfort of, and sometimes resulting in injury to, the user. In other cases the load associated with the weight of the unit may be sufficient to cause injury during a short period of use.
It is against this background, and the problems and difficulties associated therewith, that the present invention has been developed.
Certain objects and advantages of the present invention will become apparent from the following description, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
SUMMARY OF THE INVENTIONIn one aspect, the invention may be said to reside in a support arrangement for an implement, the support arrangement comprising a harness worn by a user, the harness comprising an attachment point for a first load-bearing element transferring a load associated with the implement to the attachment point, and a second load-bearing element transferring the load from the attachment point to a further point on the harness.
In a further aspect, the invention may be said to reside in a support arrangement for an implement, the support arrangement comprising a user-worn harness comprising an attachment point, a first load-bearing element transferring a substantially vertically directed load associated with the implement to the attachment point, and a second load-bearing element redirecting at least a portion of the load, at the attachment point, substantially horizontally.
In one form, the first load-bearing element is a tension member.
In one form, the second load-bearing element is a compression member.
In one form, the attachment point is at or near a shoulder joint of the user.
In one form, the attachment point is at or near a front of the user.
In one form, the further point is at or near hips of the user.
In one form, the further point is between or near the hips of the user.
In one form, the further point is at a rear of the user.
In one form, the tension member is mechanically resilient.
In one form, the compression member is mechanically resilient.
In one form, the tension member is a tether.
In one form, the tension member is flexible.
In one form, the harness comprises a shoulder harness and a belt.
In one form, the compression member extends from the attachment point to the belt.
In one form, the compression member extends beneath an arm of the user.
In one form, the implement is a tool or metal detector.
In one form, the length of the compression member is adjustable.
In one form, the length of the tension member is adjustable.
For a better understanding of this disclosure, it will now be described with respect to one or more exemplary embodiments that shall be described herein with the assistance of drawings wherein:
In the following description, like reference characters designate like or corresponding parts throughout the several views of the drawings.
DETAILED DESCRIPTIONReferring now to
Referring now to
The harness 10 also comprises a belt 14 and a yoke 16 extending from a back of the belt 14 which divides into a pair of shoulder straps 18 that terminate at spaced-apart positions at a front of the belt 14. The harness 10 is made from a strong webbing material such as nylon, polypropylene or polyester, and the shoulder straps 18 and belt 14 are padded (ie. there is padding provided between the webbing and the user) for the wearer's comfort. Pouches for items may be suspended from the harness 10.
The lengths of each of the shoulder straps 18 and the belt 14 are adjustable by way of conventional adjustment means. The length of the yoke 16 is also adjustable by virtue of being divided into two parts 16a and 16b secured to each other by way of operatively associated portions of hook-and-loop fastener material such as Velcro. The length of overlap between the two parts 16a and 16b can be decreased to accommodate taller users, or increased to accommodate shorter users.
Each shoulder strap 18 comprises an attachment point 12 in the form of a D-shaped attachment ring that is secured by stitching it to the shoulder strap 18 at a point which will be in front of, and near the shoulder of, the user when the user is wearing the harness 10.
By providing an attachment point 12 on each shoulder strap 18, the tension member can be positioned for either right or left-handed users.
Referring now to
Suspended from the eyelet 32 is a support attachment 80 (see
The buckle 84 of the support attachment 80 comprises a hook 86 about which the eyelet 32 of the tension member 30 is disposed.
With reference to
Below the attachment point 12 on each shoulder strap 18 is a hardpoint 42 in the form of a vertically and downwardly directed connector socket that is stitched into the webbing of the harness and which receives and retains an end of the compression member 40. It is envisaged that this hardpoint 42 may be manufactured by means such as moulding this from a material such as polyurethane plastic.
With reference to
Referring again to
The shape of the curvature of the compression member 40 can be varied to suit either of a left or right-handed user. The variable curvature can be achieved by means of the rod 40 being composed of two or more sections 40a and 40b, at least one of which incorporates connection means 48 (see
The harness 10 accommodates compression member 40 configured for either left or right-handed users by including a hardpoint 42 below the attachment point 12 on each shoulder strap 18, and a pair of oppositely directed horizontally aligned connector sockets 43 at the further point 13 in the back of the belt 14.
In use, the metal detector 2 is suspended from the tension member so that a substantial portion of the substantially downwardly directed load associated with the weight of the metal detector 2 is transmitted, via the tension member 30, to the attachment point 12 on the harness 10, from where the load is transmitted, via the compression member 40, to the further point 13 located on the belt 14 behind the user. A turning moment is created which attempts to force the back of the belt 14 back and away from the back of the user, this rearward force being counteracted by the padding inside the front of the belt 14, which comfortably spreads the load over the hips and across the abdomen of the user.
By integrating the compression member 40 into the harness 10 in the manner described above, the compression member 40 is not unwieldy or obtrusive, and it allows the attachment point 12 for the tension member 30 to be incorporated into and securely anchored to the harness 10 such that the attachment point 12, and an upper portion of the compression member 40, are not about or above the head of the user, where they would be liable to be damaged, obscure the user's view, and present a threat to the user when he/she is excavating, or in the event of a fall.
Moreover, by positioning the attachment point 12 at or near the shoulder joint at the front of the user, common metal detector 2 movements, such as a side-to-side sweeping motion, are not inhibited.
Throughout the specification and the claims that follow, unless the context requires otherwise, the words “comprise” and “include” and variations such as “comprising” and “including” will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers.
The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement of any form of suggestion that such prior art forms part of the common general knowledge.
It will be appreciated by those skilled in the art that the invention is not restricted in its use to the particular application described. Neither is the present invention restricted in its preferred embodiment with regard to the particular elements and/or features described or depicted herein. It will be appreciated that various modifications can be made without departing from the principles of the invention. Therefore, the invention should be understood to include all such modifications in its scope.
