Abstract

A safety restraint system for use by a worker working in a bucket, including a primary tether line that securely encircles the bucket at a position adjacent to the upper rim thereof; at least a pair of straps connected to the tether line on opposite sides of the bucket; a safety harness or aerial belt adapted to be worn by the worker and having at least a pair of clips attached thereto; and at least a pair of straps that interconnect the harness buckles to the straps on the tether line, thereby interconnecting the harness to the tether line.

Claims

1. A safety restraint system, comprising: a. bucket having a body terminating in a mouth defining a flanged rim having a peripheral diameter; b. a primary tether line placed in an encircling relation on the bucket below the flanged rim and including a first and second end, the first end being fastened to the second end such that the primary tether forms a loop, wherein said primary tether line is dimensioned to have a diameter less than the peripheral diameter of the flanged rim of said bucket, the primary tether line is prohibited from passing over the flanged rim of said bucket such that said primary tether line is retained on said bucket without anchors; b. a body harness adapted to be worn by the worker; and c. first and second straps interconnecting said harness to said primary tether line, wherein said first and second straps are selectively movable relative to and along a major portion of said primary tether line, wherein the first and second straps are sized to prevent the worker wearing the harness from bodily exiting the bucket and to prevent the primary tether from passing over the bottom of the bucket when the first and second straps are attached to the primary tether, wherein the first and second straps are positioned to attach on the opposite sides of the bucket.

DETAILED DESCRIPTION

(6) Referring to the drawings, in which like reference numerals refer to like parts throughout, there is seen a safety restraint system, designated generally by reference numeral 10, for use by a worker 100 working from a conventional bucket 200. Safety restraint system 10 is intended to be worn by worker 100 to prevent the worker from falling out of the bucket 200 and falling to the ground.

(7) Safety restraint system 10 generally comprises a primary tether line 12 that encircles and is securely fastened to bucket 200, a pair of straps 14, 16 that connect to primary tether line 12 via straps and/or buckles 18, 20, and a body harness, designated generally by reference numeral 22, adapted to be worn by worker 100 and to which the opposite end of straps 14, 16 connect via straps and/or buckles 24, 26. In a multi-person bucket, there would be double the number of connectors/attachment points. Straps 14 and 16 are movable relative to primary tether line 12 as the straps interconnecting them can be slid along the primary tether line, thus permitting repositioning of the straps as necessary for the worker to do his work and remain safe. With system 10, worker 100 is tethered to bucket 200 by way of the harness 22, straps 14, 16, and primary tether line 12, and in the event of an accidental fall from bucket 200, worker 100 will be prevented from falling to the ground and will be suspended from the bucket 200 by way of the safety restraint system 10.

(8) Body harness 22 comprises a pair of shoulder straps 28, 30 with adjustment buckles 32, 34 to permit their length to be selectively adjusted, a strap 36 that gathers the shoulder straps 28, 30 and prevents them from sliding off the worker's shoulders, and a waist 38 that is connected to the shoulder straps 28, 30 and extends around the worker's waist. A series of straps/O-rings/D-clips (collectively referred to as “fasteners”) 40 are integrated into the harness 22 at various positions to permit the connection of the harness to the straps 14, 16.

(9) Primary tether line 12 wraps around bucket 200 and is tightly fastened at a position just below the flanged rim 202 of bucket 200. As flanged rim 202 is of a peripheral dimension greater than the peripheral dimension of the rest of the exterior surface of bucket 200, primary tether line cannot ride up the exterior of bucket 200 beyond the rim 202. Moreover, the flange that forms the flanged rim 202 further serves as a stop or catch for the primary tether line 12 if it were to ride all the way up to the top of the bucket's exterior surface, thus preventing it from becoming detached from the bucket 200. In buckets without rims, placement of the primary tether beneath the boom attachment point will also serve to prevent it from becoming disengaged from the bucket.

(10) Referring to FIGS. 1 and 2, when a worker 100 is standing in the bucket 200 (FIG. 1) or is leaning forward from the bucket (FIG. 2), straps 14, 16 are anchored to primary tether line 12 at the front and rear of bucket 200. By having the straps 14, 16 extend from the front and rear of harness 22 to primary tether line 12, if worker 100 were to accidentally fall from the front of bucket 200, as could happen when leaning forward as seen in FIG. 2, an upwardly directed force will be applied to the rear strap 16 while a downwardly extending force will be applied to the front strap 14. The combination of these forces will cause the worker 100 to simply remain suspended from bucket 200 until he can either climb back into the bucket or until help arrives.

(11) Likewise, when the worker 100 is squatting within the bucket 200 as seen in FIG. 3, the straps 14 and 16 are slid front the front and rear of bucket 200 to the opposite sides bucket. This keeps the straps out of the face of the worker 100, thus not creating any distraction, while still maintaining the safety of having straps 14, 16 on opposite sides of the bucket 200.

(12) With reference to FIG. 4, an alternate embodiment of safety restraint system 10, designated 10′, is provided. Safety restraint system 10′ includes primary tether line 12′ to which a single strap 14′ is attached and which is adapted to attach to a buckle on the worker's harness (not shown in FIG. 4). This single strap 14′ in system 10′ will prevent worker (not shown in FIG. 4) from falling the beyond distance equal to the length of the strap (e.g., 2 feet) if he/she inadvertently falls from the bucket. Thus, unlike system 10, where worker 100 will be prevented from even falling out of bucket 200, system 10′ will prevent the worker from falling beyond some minimal distance from bucket 200, but will not necessarily prevent the worker from not falling out of the bucket all together.

(13) Also shown in FIG. 4, and a feature that could also be included in system 10, is a secondary tether 300 that extends between the primary tether 10 (or 10′) and the conventional boom anchor to which the basket of bucket 200 attaches. In the event the basket disengages from the boom, secondary tether 300 will prevent the basket from falling to the ground. In addition, safety restraint system 10 (or 10′) will prevent the worker from falling too far beyond the basket even if it disengages from the boom.
