The present device is in the field of dropped object prevention. More particularly, the present device is in the field of creating attachment points on tools to prevent dropped objects.
Most tools in use for construction and maintenance have either a hole or other relatively easy way of creating an attachment point. However, there are various tools on which it is difficult to create an attachment point due to their straight nature, slightly tapered handle, closed handle, or lack of handle, such as pinch bars, pry bars, digging bars, torque wrenches, breaker bar ratchets, clamps, larger spanner wrenches, larger open end wrenches, larger box style wrenches, larger combination wrenches, larger open end wrenches, sledge hammers, power tools with triggers, such as drills and saws, and other tools.
In the past, simple cinches have been used in an effort to prevent a dropped tool from falling and damaging something or injuring someone below the work site. With such a cinch, a strap is utilized, having a closed ring at one end and a loop at the other. The ring end is passed through the closed loop, or the like and pulled tight. The tool is secured in the loop that is formed by the ring end passing through the closed loop. Regardless of how tight the cinch is pulled, it is prone to loosening as the tool is being used, which can result in the tool slipping through the cinch. Subsequently, if the tool is dropped with the cinch compromised, the tool may be damaged, or it may cause injury to objects or persons below the work site. While additional measures can and have been employed, i.e., tying knots, taping the cinch loop to the tool, even these do not provide the requisite security.
It is to the above disadvantages and shortcomings of the prior art that the present disclosure is directed.
The present device is an attachment point for dropped object prevention primarily for tools where conventional attachment points are not available, although it can be used on tools that do have attachment points. The tool cinch assembly uses a strap with a loop on one end, and a ring or the like on the other, and extended webbing or other material in the form of radially extending wings, combined with a securing means, such as tape, to wrap around the tool and the wings. The wings allow for positioning the device in the proper location on the tool, and holding it there with tape or like means so the cinch strap does not become disconnected or slide off of the tool prior to or during the occurrence of a dropped object. This embodiment allows the cinch strap itself to utilize the energy created when the tool falls and snatches back to prevent the tool from falling to the ground or surface below. This embodiment of the device allows for the creation of an attachment point for tools weighing up to 35 lbs or more. V or D Rings at the other end of the strap act as an attachment point for securing the attachment to a lanyard, which prevents the tool from falling to the ground.
In the following detailed description of various embodiments of the present device, numerous specific details are set forth in order to provide a thorough understanding of various aspects of one or more embodiments of the device. However, one or more embodiments of the device may be practiced without these specific details. In other instances, well-known methods, procedures, and/or components have not been described in detail so as not to unnecessarily obscure aspects of embodiments of this device.
In the following description, certain terminology is used to describe certain features of one or more embodiments of the device. For instance, “pry bar” and “digging bar” refer to any of the numerous tools used by construction workers to apply leverage or create protrusions during the performance of their job.
Referring now more specifically to the drawings, and to
Numeral 22 designates generally a first embodiment of the present tool cinch with a stabilizer. With like parts being referenced by like numerals, the present tool cinch 22 has a main body strap 12 with a V-ring 14 at one end and a loop 18 at the other. Secured to the strap 12, between the V-ring and the loop, is a stabilizer in the form of a radially projecting wing 24. The wing has one end secured to the strap 12 with stitching or other appropriate means.
The wing itself comprises a strap 26 having, as stated, one end secured to the main body portion of the cinch. The opposite end is folded over upon itself, once, twice, or more times, and stitched or otherwise secured to the strap portion of the wing to form an abutment in the form of a catch tab 28.
An alternate embodiment is shown in
Another embodiment of the present device is shown in
The present device is shown in use in
In applying the present cinch, the tool is first captured by the cinch. As shown in
In the use and operation of the present device, the tool cinch portion, using the cinch itself, absorbs the dynamic load generated when a tool drops, and is further supported and strengthened by a protruding cross-sectional wing or wings which are held in place with either tape, heat shrink, both, or other means. The radially extending wing or wings are used to keep the cinch in place, as all dynamic load is captured at the cross section of the main cinch strap and the cross-wing or wings.
Many tools used at height are slightly tapered and/or do not have an end cap or other fixture on the end which would prevent normal chokes or cinching type products from simply sliding off the end of the tool. This is the problem this device is solving.
The wings with catch tabs are used in combination with quick wrap tape and/or with heat shrink links to hold the cinch mechanism in place. This creates a stationary cinch/choke mechanism, designed to prevent the attached tool from falling from an elevated work area when attached to an extension lanyard. The energy created at the point where the tool reaches the length of the extension lanyard creates a firm friction point, which consistently maintains control of the tool. During the recoil phase of a dropped object, the tool will spring back slightly and the cinch may tend to loosen. The attached wings secured with the quick wrap and/or heat shrink links prevent the apparatus from working its way off of the tethered tool.
The wing sizes for this apparatus can range from approximately 2″ up to approximately 12″ inches in length. The width of the wings range from approximately ½″ to approximately 2″ wide. Other sizes and lengths may also be utilized.
The wing material can be rope, woven or non-woven webbing such as nylon, polyester, vinyl, elastic, tubular or non-tubular webbing and other means. The wings have catch tabs sewn to the ends, which serve as catch points. The catch tabs provide an abutment which the securing means, such as tapes or heat shrink means, can bear against, thereby preventing the tapes, heat shrink means, or other securing means from possibly slipping off the wings. This additional level of security has not been utilized in the prior art and while other expedients have been tried, uncompromised security has not been attained until now.
The wings are secured with a variety of materials such as quick wrap tape and/or heat shrink links. Additionally, other tape materials, hook & loop fastening, and banding straps are also viable options, as well as other means. The wings are normally secured in a parallel orientation to the handle of the tool or along the main body portion of the tool. This provides maximum contact with the tool for added security. The wings normally project radially from the main cinch strap and are normally disposed perpendicular to the main cinch strap; however, other orientations are possible, such as angular, and are considered to be within the scope of the present disclosure. Similarly, the number of stabilizers can be varied from a device with a single stabilizer to ones having a plurality of stabilizers.
The cinch strap can be rope, woven or non-woven webbing such as nylon, polyester, vinyl, elastic, non-tubular webbing or tubular webbing with elastic cord or webbing sewn inside, creating a bungee style apparatus, and other means.
The loop at the top of the device is designed with a special twist to improve the gripping function of the device, as shown in
The main strap is fed through the twisted loop allowing for use with multiple sizes, as the device is adjustable in circumference. This device is effective on tools ranging from approximately 1″ to approximately 4″ in diameter. The device can, of course, be made larger or smaller to accommodate tools of virtually any size. This is another useful feature of the device.
The D-Ring and V-Ring used on both devices are used for attaching lanyard extensions for securing the device, while attached to a tool, to a reliable structure, such as a scaffold, during use as shown in
While an embodiment of a tool cinch and modifications thereof have been shown and described in detail herein, various additional changes and modifications may be made without departing from the scope of the present disclosure.
