Definitions
- the present invention relates generally to creating anchor points for attaching safety lanyards or straps to hand tools. More particularly, the present invention relates to an improved slide-on anchor point.
- attachment devices have been devised to secure hand tools from such a drop.
- Many tools are manufactured with captive holes, to allow the connection of a safety line.
- lanyards and D-rings have been built into many hand power tools to allow attachment of lines to the tool at one end, and a user's body at the other.
- One method is to tape a safety strap to the handle of such a tool. Python Safety, Inc. makes such a tape called Quickwrap TapeTM for this purpose. Another method is used by Tool Safety Solutions LTD, and involves using a heat sensitive tape to secure a section of strap to the tool, and then apply heat to the tape allowing it to shrink and hold the section of strap in place.
- a disadvantage of the above tape method is that tape can lose its adhesive properties over time and under harsh environmental conditions, creating uncertainty when the tool safety strap connection might fail.
- the heat shrink method has disadvantages as well.
- the heating step might either damage the handle or section of safety strap being used. If the heat shrink adhesive is over heated, the safety strap might well be weakened by the heating process and the weakened safety strap within the heat shrink adhesive might go undetected. An unexpected failure of the safety strap might then occur. Further, the heating step can release undesirable toxic combustion products.
- heat shrink sleeves require use of a thin walled product, required for process safety and optimum rate of heat conduction through the heat shrink material. Such a thin-walled product may not be durable or safe in securing a strap to a heavy hand tool, or supporting the weight of the tool if the tool is dropped.
- the cold shrink with removable core method involves multiple pieces and cannot be easily adjusted once in place, and are difficult to deploy in the field. Further, it is a one use product.
- the slide-on invention by Moreau has multiple pieces and is designed such that the bore that captures the hand tool needs to be smaller than the diameter of the area of the hand tool to which it to be applied. This makes application difficult, and the multiple pieces make installation in the field inconvenient and sometimes impossible. Further, the small circular bore size of the Moreau invention restricts the flexibility of the invention for use in tools with non-circular shapes and varying diameters.
- a preferred embodiment of the invention includes a pliable core portion captured by a wheel. It further includes a loop member, containing an eyelet for attaching a safety strap. The loop member is attached to the outer surface of the wheel and configured such that it may revolve freely about the wheel.
- the core portion is configured with an opening that is preferably star shaped. The circumference of the outer perimeter of the star shaped opening is preferably larger than the surface of the object to which the anchor point is to be applied.
- Figure 1 is a perspective view of a preferred embodiment of the invention.
- Figure 2 is a front elevation view of a preferred embodiment of the invention.
- Figure 3 is a perspective exploded view of a preferred embodiment of the invention.
- Figure 4 is a perspective view of a three star embodiment 110 of the invention.
- Figure 5 is a perspective view a preferred embodiment of the invention creating an anchor point 150 on an opened end wrench 170.
- Figure 6 is a perspective view of three star embodiment 210 creating an anchor point on hex key wrench 220.
- Figure 7 is a perspective view of an alternate embodiment of the invention showing an alternate loop member 112 configuration on anchor point 310.
- Figure 8 is a perspective view of an alternate embodiment of the invention showing an alternate loop member configuration 412 on anchor point 410.
- Figure 9 is a perspective view of an alternate embodiment of the invention showing a different loop member 320 configuration.
- Figure 10 is a perspective view of an alternate embodiment of the invention showing a different loop member 412 configuration.
- Figure 11 is a perspective view of an alternate embodiment of the invention showing a different loop member 512 configuration and an alternate star shaped opening 524.
- Figure 12 is a perspective view of an alternate embodiment of the invention showing a different loop member 612 configuration and an alternate shaped opening 624.
- FIGS. 1 - 3 depict a preferred embodiment of the invention.
- the basic components of a preferred embodiment of anchor point 10 are loop member 12, wheel 14 and core 16.
- Loop member 12 comprises eyelet 18 and race engaging member 20.
- Race engaging member 20 is secured onto wheel 14 such that race engaging member 20 can revolve about wheel 14 on race 22.
- Wheel 14 comprises rims 30 and 34 that define race 22.
- Wheel 14 is preferably constructed of an ABS material (Acrylonitrile-Butadiene-Styrene), but can be made from metal, aluminum, carbon fiber, nylon, other hard plastic or rigid material. Wheel 14 captures core 16 to hold core 16 securely and to constrict the ability of core 16 to expand when engaged with an object to hold the inserted object securely, creating a stable anchor point. Wheel 14 has grooves 17 on its interior perimeter 19.
- Core 16 is preferably made of a vulcanized alloy consisting mostly of fully cured EPDM rubber particles encapsulated in a polypropylene matrix (TPV). Core 16 is preferably of a Shore A hardness between 40 and 80. Other rubbers or suitably pliable material may also be used. Core 16 preferably comprises cylinder 32, tongue portions 15 on its exterior diameter 32, star shaped openings 24 and recessed flange 46 The maximum exterior diameter 32 of core 16 is preferably larger than the interior diameter 19 of wheel 14 to insure a firm capture of core 16 by wheel 14. Tongue portions 15 are configured to engage grooves 17 when core 16 is inserted into wheel 14. This engagement serves to inhibit rotational and lateral movement of core 16. Wheel rim 30 serves to engage recessed flange 46 of core 16 to also resist any lateral movement of core 16 after it is captured by wheel 14.
- TPV polypropylene matrix
- star shaped opening 24 runs the length of the longitudinal axis of core 16.
- the star shaped opening preferably comprises 6 points 48. More or less points, or different spacing of points 48, can be used depending on the application.
- voids 28 can be made larger to increase the amount of material that can be compressed.
- the diameter of the portion of the hand tool or other object on which an anchor point is to be established is smaller than the outside diameter 36 of star shaped opening 24. This allows for points 48 to effectively engage the surface of the object inserted into star shaped opening 24 to establish a secure anchor point.
- the portion of the hand tool or other object on which an anchor point is to be created needs to be larger than inside diameter 38 to create a secure anchor point.
- membrane 26 can be constructed within void 28 of star shaped opening 24 as depicted in fig. 2.
- membrane 26 is pierced by the object inserted into star shape opening 24. Pierced membrane 26 supplies additional resistance to movement of the inserted object, and increases stability for the anchor point as it engages the inserted object.
- Loop member 12 is preferably constructed from ABS material. Upon assembly, rim 30 is preferably sonic welded to wheel 14.
- anchor point 110 is comprised of loop member 112, wheel 114 and core 116.
- This embodiment intended for smaller objects, has star shaped opening 124 that has three points 138 and three voids 128.
- Loop structure 112 is comprised of eyelet 118 and race engaging member 120.
- anchor point 110 is shown attached to an open end wrench 120.
- anchor point 210 is shown attached to a hex key 220.
- FIG. 7 depicts the plane of eyelet 318 perpendicular to race engaging member 320.
- Loop member 320 is a split ring configuration, which demonstrates an alternate method of mounting loop member 320 on the race (not visible).
- Figure 8 depicts loop member 412 of anchor point 410 in a more planar configuration for use in tighter spaces.
- Figure 9 depicts loop member 512 is a tube steel configuration depicting an alternate embodiment and an alternative method of mounting loop member 512 on race 522.
- Figure 10 depicts anchor point 610 comprising loop member 612 in a spring steel configuration, which demonstrates an alternate method of mounting loop member 612 to the race (not visible).
- Figure 11 depicts anchor point 710 with the spring steel configuration of loop member 712 comprising eyelet 718 and race engaging member 720 (similar to that of Figure 10) and an alternative opening configuration 724 in pliable core 716.
- Figure 12 depicts an alternate embodiment anchor point 810 depicting a lower profile loop member 812 in a spring steel configuration. Also depicted is alternative design of opening 824 in core 816.
