Example embodiments generally relate to an outdoor power tool equipment harness and, more particularly, relate to an additional component for a back plate of the outdoor power tool equipment harness that can enable the harness to be worn by a wider range of users.
Property maintenance tasks are commonly performed using various forms of outdoor power equipment that are configured for the performance of corresponding specific tasks. Some of those forms of outdoor power equipment are designed to be effective at performing the specific tasks in situations that could be relatively brief, or could take a long time including, in some cases, a full day of work. When operating outdoor power equipment for a long period of time, fatigue can play a role in the operation of the outdoor power equipment. Regardless of how long the operator uses the outdoor power equipment, it is important that the operator remains able to effectively maneuver the outdoor power equipment device to achieve the best possible results for the property maintenance tasks.
To help reduce the speed and severity of the onset of fatigue, operators may wear a harness that may better distribute the force felt by the operator from the weight of the outdoor power equipment. However, the fitment of the harness may determine the effectiveness of the harness at minimizing fatigue. The harness may not be one-size-fits-all, and for operators that are on the larger of the extreme ends of the spectrum of operator size, the traditional harness may be an inadequate solution. Thus, an adaptation for further adjustment of the harness is necessary in many cases.
Some example embodiments may provide for a harness for carrying outdoor power equipment. The harness may include a back plate, an extension plate removably operably coupled to the back plate, a joint plate configured to pivotably operably couple to the extension plate or the back plate, a shoulder strap assembly operably coupled to the joint plate and a belt operably coupled to the back plate and configured to rest proximate to a waist of an operator. The extension plate may be disposable between the back plate and the joint plate and may be fixed relative to the back plate. The joint plate may be configured to pivot relative to the extension plate responsive to movement of the operator wearing the harness.
Some other examples may provide for an extension plate for a harness for operating outdoor power equipment. The extension plate may include a base portion, a first retention clip that may be formed in the base portion and may be configured to operably couple the extension plate to a back plate of the harness, a second retention clip that may be formed in the base portion and may be configured to operably couple the extension plate to the back plate, and an extended retention orifice that may be formed in the base portion and may be axially aligned with the first and second retention clips. The extension plate may be fixed relative to the back plate when the extension plate may be operably coupled to the back plate. The first and second retention clips may be axially aligned along a longitudinal axis of the extension plate.
Having thus described some example embodiments in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Some example embodiments now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all example embodiments are shown. Indeed, the examples described and pictured herein should not be construed as being limiting as to the scope, applicability or configuration of the present disclosure. Rather, these example embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like reference numerals refer to like elements throughout. Furthermore, as used herein, the term “or” is to be interpreted as a logical operator that results in true whenever one or more of its operands are true. As used herein, operable coupling should be understood to relate to direct or indirect connection that, in either case, enables functional interconnection of components that are operably coupled to each other.
In some example embodiments, an operator may wear a harness while actively operating outdoor power equipment. The harness may be utilized for operably coupling to outdoor power equipment that may be too heavy or otherwise cumbersome to effectively operate for extended periods of time. The harness may include at least one leg plate, hip pad or other contact pad structure that may separate the outdoor power equipment device from direct physical contact with the operator. Furthermore, the nature of performing lawn care and maintenance tasks may often imply that anyone should be able to operate the outdoor power equipment, regardless of the operator's physical size and strength. In this regard, a standard harness may not properly fit all potential operators of the outdoor power equipment, even with a range of sizes built into the standard harness. As such, it may be desirable to expand the range of sizes of the harness so that operators that may exceed the range of sizes may still wear the harness when operating outdoor power equipment. Thus, creating an extension plate for the harness may allow more operators to effectively and comfortably operate outdoor power equipment for extended periods of time while minimizing the onset of fatigue from carrying the outdoor power equipment device. Other improvements may also be possible, and the improvements can be made completely independent of each other, or in combination with each other in any desirable configuration. Accordingly, the operability and utility of the harness may be enhanced or otherwise facilitated.
The back plate 110 may also be operably coupled to the belt 140. The belt 140 may be configured to secure to an operator's waist when the operator is wearing the harness 100. In this regard, the belt 140 may distribute some of the load force from the weight of the outdoor power equipment off of the operator's shoulders, so as to minimize the onset of operator fatigue when using the outdoor power equipment for an extended period of time. The back plate 110 may also be operably coupled to the side strap 150 which may be configured to operably couple to the outdoor power equipment device directly or indirectly (e.g., via a hook assembly). In some embodiments, the side strap 150 may also be operably coupled to the leg plate, hip pad or other contact pad structure so that the outdoor power equipment device is separated from direct contact with the operator.
The harness 200 may also include an extension plate 270. As mentioned above, the size of the harness 200 may be adjusted by changing the position at which the joint plate 220 operably couples to the back plate 210. However, in some embodiments, the back plate 210 may not include an ideal position for the joint plate to operably couple to the back plate 210 for larger operators. Rather than have an entirely different harness 200 for larger operators to wear, the extension plate 270 of some embodiments may provide the harness 200 with the ability to be adjusted to a size larger than the largest size possible on the unaltered back plate 210. The extension plate 270 may be configured to operably couple to both the back plate 210 and the joint plate 220. In this regard, the extension plate 270 may be disposed between the back plate 210 and the joint plate 220 when the extension plate 270 is installed. As such, the joint plate 220 may operably couple to the extension plate 270 in the same manner as the joint plate 220 would otherwise operably couple to the back plate 210. Further detail about the extension plate 270 and its corresponding structure and function will be described in relation to later figures below.
The plate member 215 may also include a waist portion 300 that may be configured to operably couple to the belt 240. The entire plate member 215, and particularly the waist portion 300, may be curved so that the back plate 210 conforms to the natural shape of the operator's back. In this regard, the harness 200 may provide the best possible fit for the operator and may therefore be more effective in minimizing the fatigue levels of the operator due to the extended use of the outdoor power equipment. In addition to the curvature of the plate member 215, the plate member 215 of some embodiments may also include a plurality of accessory apertures 310 to which the side strap 250 and other accessories may operably couple. The locations of the accessory apertures 310 may be determined based on the type of accessory intended to operably couple thereto so that the operator has ideal accessibility to all attachments and their respective functions. In some cases, the plate member 215 may further include a plurality of structural cutouts strategically disposed all over the back plate 210 as a method of saving weight and improving cooling of the operator without compromising on the structural integrity of the back plate 210. In some embodiments, the plate member 215 may be formed from a plastic material via an injection molding process in order to minimize manufacturing costs as well as provide a lightweight, yet strong, material to meet the specific needs of the back plate 210.
Referring now to
In some embodiments, the first and second retention clips 320 and 321 may be configured to operably couple to the retention orifices 280 via a snap fit. In this regard, the first and second retention clips 320 and 321 may each include a first clip member 322, a second clip member 324, and a pair of diametrically opposed guide protrusions 326. The diametrically opposed guide protrusions 326 may be configured to align with the guide slots 282 of each retention orifice 280. When the guide protrusions 326 align with the guide slots 282, the first and second retention clips 320 and 321 may be inserted into the retention orifices 280. In this regard, the first clip member 322 and the second clip member 324 may be forced towards each other (in the direction of arrows 340) responsive to the first and second retention clips 320 and 321 being pushed past a retention lip 286 of the retention orifice 280. Responsive to the first clip member 322 and the second clip member 324 passing the retention lip 286, the first clip member 322 and the second clip member 324 may be biased away from each other, and the first and second retention clips 320 and 321 may accordingly snap into their operable coupling with the retention lip 286 in the retention orifice 280. In this regard, due to the alignment of the guide protrusions 326 in the guide slots 282, the first and second retention clips 320 and 321 may not rotate with respect to their respective retention orifice 280 responsive to being operably coupled thereto.
As mentioned above, the joint plate 220 may be configured to pivotably operably couple to the back plate 210 or to the extension plate 270. In this regard, the joint plate 220 may include a pivotable retention clip 350. The pivotable retention clip 350 may be configured to operably couple with any of the retention orifices 280 of the back plate 210, or to the extended retention orifice 285 of the extension plate 270. As such, the pivotable retention clip 350 may include guide members 360 which, similar to the guide protrusions 326, may be configured to align with guide slots 282 so that the pivotable retention clip 350 may be pushed into the retention orifice 280 or the extended retention orifice 285. Responsive to the pivotable retention clip 350 being inserted in the retention orifice 280 or the extended retention orifice 285, the guide members 360 may clear the retention lip 286, such that the pivotable retention clip 350 may then rotate and the guide members 360 may slide along the retention lip 286. In some embodiments, the pivotable retention clip 350 may further include a locking member 370. The locking member 370 may include a release button 372 and a locking arm 374. In some embodiments, the locking member 370 may be biased upward into a locked position that the locking member 370 assumes when no outside forces are present. Applying a force to either the release button 372 or to the locking arm 374 may depress the locking member 370 out of the locked position and into an unlocked position. In some embodiments, the locking arm 374 may be disposed roughly halfway between the diametrically opposed guide members 360, on a perimeter of the pivotable retention clip 350.
The locking member 370 may be forced into the unlocked position responsive to the pivotable retention clip 350 being inserted into the retention orifice 280 or the extended retention orifice 285 by the retention lip 286 applying a force to the locking arm 374. Accordingly, responsive to the pivotable retention clip 350 being rotated within the retention orifice 280 or the extended retention orifice 285, the locking arm 374 may align with one of the guide slots 282, which may then allow the locking member 370 to release from the unlocked position and snap into the locked position due to the biasing force of the locking member 370. As such, the locking arm 374 may be confined to an area defined by the guide slot 282. Accordingly, the pivotable operable coupling of the joint plate 220 to the back plate 210 or to the extension plate 270 may be complete. The pivotable retention clip 350 may be configured to pivot relative to the back plate 210 or to the extension plate 270 within the operable coupling to the retention orifice 280 or the extended retention orifice 285. In some embodiments, the locking arm 374 may not move outside of the area defined by the guide slot 282 unless a force is applied to the release button 372 or to the locking arm 374 to depress the locking arm 374 below the retention lip 286. Thus, the guide slot 282 may therefore define a range of possible pivot angles for the pivotable retention clip 350.
Some example embodiments may provide for a harness for carrying outdoor power equipment. The harness may include a back plate, an extension plate removably operably coupled to the back plate, a joint plate configured to pivotably operably couple to the extension plate or the back plate, a shoulder strap assembly operably coupled to the joint plate and a belt operably coupled to the back plate and configured to rest proximate to a waist of an operator. The extension plate may be disposable between the back plate and the joint plate and may be fixed relative to the back plate. The joint plate may be configured to pivot relative to the extension plate responsive to movement of the operator wearing the harness.
The harness of some embodiments may include additional features, modifications, augmentations and/or the like to achieve further objectives or enhance performance of the harness. The additional features, modifications, augmentations and/or the like may be added in any combination with each other. Below is a list of various additional features, modifications, and augmentations that can each be added individually or in any combination with each other. For example, the harness may further include a leg plate which may be operably coupled to the harness and may be configured to support an outdoor power equipment device. In an example embodiment, the back plate may include a plate member with at least three retention orifices formed therein. In some cases, each retention orifice may correspond to a different size of the harness. In an example embodiment, the joint plate and the extension plate may each be configured to operably couple to the retention orifices. In some cases, each retention orifice may be substantially circular in shape. In an example embodiment, each retention orifice may include a pair of diametrically opposed guide slots centered along a longitudinal axis of the back plate. In some cases, the extension plate may include a base portion, a first retention clip and a second retention clip. In an example embodiment, the first and second retention clips may be configured to operably couple with the retention orifices in the back plate. In some cases, the first and second retention clips may each include a pair of diametrically opposed guide protrusions that may align with the diametrically opposed guide slots of the retention orifices. In an example embodiment, the first and second retention clips may be configured to operably couple to respective ones of the retention orifices of the back plate via snap fits. In some cases, the extension plate may further include an extended retention orifice which may be axially aligned with the first and second retention clips. In an example embodiment, the extended retention orifice may be axially aligned along a longitudinal axis of the back plate when the extension plate may be operably coupled to the back plate. In some cases, the joint plate may be configured to pivotably operably couple to one of the retention orifices on the back plate, or to the extended retention orifice when the extension plate may operably coupled to the back plate. In an example embodiment, the joint plate may include a pivotable retention clip. In some cases, the pivotable retention clip may include a pair of diametrically opposed guide members and a locking member which may be disposed on a perimeter of the pivotable retention clip between the guide members. In an example embodiment, the guide members may be configured to align with the guide slots of the retention orifices before the pivotable retention clip may be operably coupled with the retention orifice, and may be configured to misalign with the guide slots after the pivotable retention clip may be operably coupled with the retention orifice. In some cases, the locking member may be biased into a locked state responsive to the pivotable retention clip operably coupling with the retention orifice and the locking member aligning with one of the guide slots. In an example embodiment, the guide slot may restrict the motion of the pivotable retention clip responsive to the locking member entering the locked state. In some cases, the locking member may be configured to enter an unlocked state responsive to a force provided by the operator.
Some other examples may provide for an extension plate for a harness for operating outdoor power equipment. The extension plate may include a base portion, a first retention clip that may be formed in the base portion and may be configured to operably couple the extension plate to a back plate of the harness, a second retention clip that may be formed in the base portion and may be configured to operably couple the extension plate to the back plate, and an extended retention orifice that may be formed in the base portion and may be axially aligned with the first and second retention clips. The extension plate may be fixed relative to the back plate when the extension plate may be operably coupled to the back plate. The first and second retention clips may be axially aligned along a longitudinal axis of the extension plate.
The extension plate of some embodiments may include additional features, modifications, augmentations and/or the like to achieve further objectives or enhance performance of the harness. The additional features, modifications, augmentations and/or the like may be added in any combination with each other. Below is a list of various additional features, modifications, and augmentations that can each be added individually or in any combination with each other. For example, a joint plate may be configured to pivotably operably couple to the harness via the extension plate. In an example embodiment, the extension plate may be configured to operably couple to the back plate. In some cases, the back plate may include a plate member with at least three retention orifices formed therein. In an example embodiment, each retention orifice may correspond to a different size of the harness. In some cases, each retention orifice may include a pair of diametrically opposed guide slots which may be centered along a longitudinal axis of the back plate. In an example embodiment, the first and second retention clips may be configured to operably couple with respective ones of the retention orifices. In some cases, the first and second retention clips may each comprise a pair of diametrically opposed guide protrusions that may be configured to align with the guide slots. In an example embodiment, the first and second retention clips may be configured to operably couple to respective ones of the retention orifices via snap fits. In some cases, the extension plate may further include an extended retention orifice that may be axially aligned with the first and second retention clips. In an example embodiment, the extended retention orifice may be axially aligned along the longitudinal axis of the back plate when the extension plate may be operably coupled to the back plate. In some cases, the joint plate may be configured to pivotably operably couple to the extension plate at the extended retention orifice. In an example embodiment, the joint plate may be configured to operably couple to the extension plate via a pivotable retention clip. In some cases, the pivotable retention clip may include a pair of diametrically opposed guide members and a locking member that may be disposed on a perimeter of the pivotable retention clip between the guide members. In an example embodiment, the guide members of the pivotable retention clip may be configured to align with the guide slots of the extended retention orifice before the joint plate may be operably coupled with the extension plate, and may be configured to misalign with the guide slots after the joint plate may be operably coupled with the extension plate. In some cases, the locking member may be biased into a locked state responsive to the joint plate operably coupling with the extension plate and the locking member aligning with one of the guide slots. In an example embodiment, the locking member may restrict the motion of the pivotable retention clip responsive to entering the locked state. In some cases, the locking member may be configured to enter an unlocked state responsive to receiving a force.
