This invention relates to lineman safety and tool belts, and more particularly, to a lineman's belt that is adjustable and has additional safety features relating to the adjustable features.
Lineman must climb telephone or utility poles to construct or maintain electrical power lines, telecommunications lines and distribution lines. They wear a lineman belt around their waist for the dual purpose of carrying tools and to clip to a safety or climbing rig. The climbing rig is a rope or similar structure that goes around the pole and helps the lineman stay in contact with the pole. It is clipped to the lineman belt with carabiners or other clips selectively fastened to D rings on the belt. Safety rigs are also used to ensure that the lineman does not fall if he loses his grip or his gaffs cuts out from the pole.
As the lineman climbs the pole and encounters an obstacle, such as a cross arm, the various rigs must be unclipped and reclipped to the D rings as the lineman passes the obstacle. Previous versions of lineman belts include a single set of D rings, known as 2D belts, have one D ring at each end of the belt. More recent versions have two belts, with a set of D rings on each end of both straps and are therefore referred to as 4D belts. The two belts in such versions are identified as primary and secondary, with the primary typically being the larger to accommodate tools and tool accessories.
Lineman belts are typically constructed of leather, nylon or a combination of both. In the past, the belts were sized similar to a man's dress belt, in inches, with fixed adjustment holes. This allows only limited adjustment, however, which is dictated by the spacing and number of holes. It does not accommodate the gaining and losing of weight or changes in bulk due to seasonal clothing. A lineman's work is outdoors in the weather, subject to rain, ice and winds, and is highly dangerous even in the best of conditions. Their safety while on the job is of extreme importance, and their gear needs to be able to accommodate them regardless of what they need to wear to protect themselves for the conditions of the day or as they gain or lose weight over their careers. The existing prefixed adjustment holes of lineman's belts are not well-suited to addressing the fluctuating needs of the individual lineman to maintain the D rings in an ideal position.
Some safety harnesses, such as those used by climbers and emergency rescuers, are known to be adjustable. For instance, the emergency harness disclosed in United Kingdom Patent Number GB2474484 and the safety harness of U.S. Pat. No. 7,631,728 demonstrate that load-bearing harnesses can include adjustable straps. Even hip belts, such as those disclosed in U.S. Pat. No. 8,459,518 which are intended to be worn around the waist and to couple to other items such as backpacks. However, none of these relate to the specific needs of the lineman, requiring both support and safety for long periods of time in all weather conditions.
So far, there is only one adjustable lineman belt currently on the market, the Adjustable Short Back Belt™, Model #20192 CM made by Buckingham Manufacturing Co., Inc. (Binghamton, New York). This 4D lineman belt has two belt straps, each bearing a set of D rings. Both the belts are adjustable to vary their length. However, one of the adjustable belts is only slidably connected to the corresponding D rings. When the belt is adjusted, it is pulled through the D rings to reestablish its position on the body. Because of this, the distance between the D rings does not change when the corresponding belt is adjusted. Therefore, as the belt is lengthened, the corresponding D rings begin to drift from being centered on the midpoint of the body when the device is worn. As the circumference expands, this offset drift becomes increasingly exaggerated. This offset drift from center translates to an offset weight distribution, leading to uncomfortable wear over time, awkward positioning for access to tools, undue wear and tear on the device from the uneven weight and load distribution, and increased safety risks.
There is therefore still room for improvement in the field of lineman safety belts, specifically adjustable belts.
An adjustable lineman safety belt is disclosed having a primary strap and auxiliary strap both separately attached to a common body and each independently and selectively adjustable to lengthen or shorten the corresponding strap. This allows the lineman belt to be adjusted to fit a user despite increased or decreased bulk from seasonal clothing or gear necessary for weather conditions, such as sweaters, coats, and insulated pants, or from simple weight gain or loss experienced over time in the industry. This flexibility also reduces the number of belts that must be stocked by retailers.
Each adjustable strap is also fixedly secured to a D ring at each end. The change in length of the primary or auxiliary strap therefore similarly varies the distance between the associated D rings, maintaining the D rings at equidistant positions from the midline of the body of the lineman belt and therefore maintaining the weight distribution and the safety and integrity of the belt. Despite being adjustable, the primary and auxiliary straps are also movably secured to the body of the belt.
Each of the primary and auxiliary straps includes a fixed portion and an adjustable portion, with an adjustment member connecting the two portions. The adjustment members are buckles or similar hardware that permit selective securing and release of the adjustable portion of the strap thereto. The adjustable portion of each strap is therefore selectively moveable relative to the adjustment member, such as by sliding, until a desired length is achieved to lengthen or shorten the corresponding strap. Sizing guides are located on or in proximity to each of the primary and auxiliary straps to facilitate reliable and repeatable changes in strap length. The lineman belt also includes a cover disposable in at least partially covering relation to the adjustment member on each of the primary and auxiliary belts to protect the adjustment members from misadjustment or inadvertent interference while the belt in is use. The cover(s) may be selectively movable between an open position providing full access to the adjustment member and a closed position in which the cover is positioned in covering relation over the adjustment member to protect it and the adjustable portion of the corresponding strap from being accidentally bumped out of secure position when the belt is in use.
Safety straps are also provided and connect the auxiliary strap to the body of the lineman belt while also permitting movement for varying the length of the auxiliary strap. Each end of the auxiliary strap may have a safety strap which is secured to the body. The safety straps therefore prevent full separation of the auxiliary strap from the lineman belt despite its adjustability. Similarly, drop straps connect the belt tongue to the body and/or safety strap, preferably at each end of the body, for added security in case of a fall. The drop straps also help shore up the integrity of the body against ripping, pulling, tearing and similar damage which may be caused by prolonged stress from load-bearing weight.
The adjustable lineman safety belt, together with its particular features and advantages, will become more apparent from the following detailed description and with reference to the appended drawings.

As shown in the accompanying drawings, and specifically
The adjustable lineman safety belt 100 includes a primary strap 120 movably attached to the body 110 at least through terminal D rings 121a, 121b. The primary strap 120 extends along the length of the body 110 between a first primary D ring 121a at one end and a second primary D ring 121b at the opposite end. Accordingly, the primary strap 120 defines the distance between the first and second primary D rings 121a, 121b. The primary strap 120, also referred to as the “dee piece” or “D saddle” in the lineman industry, runs near one edge or perimeter of the body 110 when the lineman safety belt 100 is worn, which may be the top or bottom of the belt 100 depending on the preference of the wearer. In some embodiments, as in
A belt tongue 132 floats over and partially covers the primary strap 120, as shown in
The adjustable lineman safety belt 100 also includes an auxiliary strap 140 attached to and extending along the length of the body 110. The auxiliary strap 140 is spaced apart from the primary strap 120 on the body 110, and in at least one embodiment is substantially parallel to the primary strap 120. For instance, the auxiliary strap 140 extends along the opposite longitudinal perimeter of the body 110 from the primary strap 120. Though described at the perimeter of the body 110, the primary and auxiliary straps 120, 140 may be proximate to, adjacent or near the perimeter and are not necessarily flush with the perimeter of the body 110. The auxiliary strap 140 extends between and is securely affixed to a first auxiliary D ring 141a at one terminal end and to a second auxiliary D ring 141b at the opposite terminal end. Accordingly, the auxiliary strap 140 defines the distance between the first and second auxiliary D rings 141a, 141b. The auxiliary D rings 141a, 141b are used to connect the safety rig which may act as a fall restriction device in case of emergency. The auxiliary strap 140 and D rings 141a, 141b must be able to catch the wearer in the event of an unexpected fall or as a back-up to the primary strap 120.
Because the D rings are used as attachment points for climbing and safety rigs that enable a user to ascend and descend a utility pole, the D rings must be able to distribute weight evenly across the body 110. The D rings in each respective pair are therefore disposed substantially equidistant from the midpoint of the body 110 when worn by a user, with the first and second primary D rings 121a, 121b being substantially equidistant from one another and the first and second auxiliary D rings 141a, 141b being substantially equidistant from one another. This allows for even weight distribution over the body 110 and stabilizes the entire assembly. The D rings 121a, 121b, 141a, 141b may be any size or gauge. The primary D rings 121a, 121b may be the same size as the auxiliary D rings 141a, 141b in some embodiments, though in at least one embodiment the primary D rings 121a, 121b may be larger in size than the auxiliary D rings 141a, 141b. The D rings 121a, 121b, 141a, 141b may be made of any suitable material, such as but not limited to steel.
The primary and auxiliary straps 120, 140 each include a fixed portion of a fixed length and an adjustable portion of adjustable or variable length, each secured at one end to a D ring. These are best shown in the depictions in

The adjustment members 125, 145 may be a buckle, slide or other suitable fastener capable of selectively and releasably securing a length of strap. In some embodiments, the adjustment members 125, 145 may include distinct apertures through which the fixed portions 123, 143 or adjustable portions 124, 144 of the first and second straps 120, 140 may pass through in securing to different sections of the adjustment members 125, 145. In certain embodiments, the adjustment members 125, 145 may include teeth to facilitate gripping of the straps, though these are not required.
Each strap 120, 140 is adjustable separately and independently of the other. This allows the dimension around the wearer provided by the top and bottom of the adjustable lineman safety belt 100 to be adjusted independently, which is helpful since the straps 120, 140 hit at different points on the wearer such as the waist, torso or hips. Each of these areas may naturally have different dimensions according to anatomical differences in the wearer. They may also be subject to different levels of modification by clothing that can change with the weather conditions. For instance, adding a sweater will necessitate the adjustment around the torso but not necessarily around the hips. A person may put on or lose weight more around the waist than other sections, requiring greater adjustment in this area than the others. In addition, the straps 120, 140 do not need to be adjusted in the same direction as one another. Thus, one can be shortened and the other lengthened or kept at a constant length. Having the primary and auxiliary straps 120, 140 separately adjustable independently of one another provides maximum flexibility of use to this adjustable lineman safety belt 100.
The straps 120, 140 may each be varied in length by loosening the adjustable portion 124, 144 within the respective adjustment member 125, 145, thereby creating slack in the adjustable portion 124, 144 and in the looped portion passing through the adjustment member 125, 145, as shown in
As the length of the primary strap 120 and/or auxiliary strap 140 is varied, the corresponding distance between D rings 121a, 121b, 141a, 141b will similarly be varied. This allows the D rings 121a, 121b, 141a, 141b to remain substantially equidistant from the lateral midpoint of the body 110 despite the variation in length. This is a departure from other adjustable lineman belts, such as the Adjustable Short Back Belt™ made by Buckingham, which does not allow for the distance between the D rings to be similarly adjusted as the straps lengthen or shorten. In the Buckingham adjustable belt, for instance, the top belt or strap slides through the corresponding D rings and is not affixed thereto. Accordingly, the distance between D rings on the Buckingham belt does not change as the corresponding strap is lengthened or shortened. As the top belt or strap is adjusted to increase in length, creating a widening circumference about the wearer, the corresponding D rings will begin to drift or migrate so they are no longer centered on or equidistant from the lateral midpoint of the belt body. A similar shift to off-center occurs when the top belt is shortened, but in the opposite direction. This offset orientation is uncomfortable for the wearer, distributing the weight of the wearer unevenly. This differential weight distribution can lead to unsafe conditions, including damage to the device and possible fall. It also can impair accessibility of the tools carried by the belt tongue since they will no longer be centered on the device. The present invention solves these problems by making the distance between each set of D rings adjustable with the respective primary and auxiliary straps 120, 140 so the orientation of the D rings 121a, 121b, 141a, 141b is always substantially equidistant from the lateral midpoint of the body 110 for even weight distribution to maintain balance, safety and accessibility, regardless of how long or short the straps 120, 140 are made.
The adjustable lineman safety belt 100 may also include sizing guides 118 for each strap 120, 140 to indicate various sizes. The indicia of the sizing guide 118 act as reference points for the user when adjusting the straps 120, 140 for quickly and reliably reaching a desired size. They may therefore also indicate different distances between the corresponding primary D rings 121a, 121b or auxiliary D rings 141a, 141b. The sizing guide 118 may be located on the straps themselves, such as on the adjustable portion 144 of the auxiliary strap 140 as seen in
The adjustable lineman safety belt 100 also includes sleeves which are secured to the body 110 and slidably receive and retain a portion of the strap 120, 140 therein. For instance, as previously discussed the adjustable lineman safety belt 100 may include at least one primary sleeve 113, shown in
Similarly, the adjustable lineman safety belt 100 may also include at least one auxiliary sleeve 115 affixed to the body 110 such as by stitching and loops over the auxiliary strap 140 to movably secure the auxiliary strap 140 to the body 110. The auxiliary sleeve(s) 115 are configured and dimensioned to allow the strap 140 to pass therethrough and be moveable therein, such as slidably moveable. There may be an auxiliary sleeve 115 covering the fixed portion 143 and another covering the adjustable portion 144 of the auxiliary strap 140 and may be dimensioned to receive the tail 148 of the adjustable portion 144 to keep it out of the way during use. The auxiliary sleeves 115 may be narrower in dimension than the auxiliary D rings 141a, 141b and the second adjustment member 145 to permit passage of the auxiliary strap 140 therethrough but restrict passage of the connected auxiliary D rings 141a, 141b and the second adjustment member 145. In this way, the auxiliary sleeve(s) 115 limits or controls the minimal or shortest length the auxiliary strap 140 may take, and therefore the minimal distance between the auxiliary D rings 141a, 141b.
The adjustable lineman safety belt 100 also includes at least one safety strap 116 having a length and securely affixed to the body 110 and to the auxiliary strap 140, as shown in
In at least one embodiment, as shown in
As shown in
As shown in
The adjustable lineman safety belt 100 also includes a cover in proximity and covering relation to each of the adjustment members to prevent them from accidental movement or adjustment during use. For instance, the belt tongue 132 may form a first cover 133 over the first adjustment member 125, as seen in
The adjustable lineman safety belt 100 also includes a second cover 134 positioned in proximity to the second adjustment member 145. The second cover 134 is selectively movable between an open position in which the second adjustment member 145 is fully accessible and a closed position in which the second cover 134 is positioned over the second adjustment member 145 to cover it and prevent it from being accessed. Accordingly, the second cover 134 may be fully covering the second adjustment member 145 in the closed position. The second cover 134 may include a panel that is larger than the dimensions of the second adjustment member 145 so as to fully cover and/or obscure the second adjustment member 145 when placed over it in the closed position. The second cover 134 is selectively releasably securable to the body 110 by at least one fastener 136, which may be snaps as seen in
