Field
The disclosed concept relates generally to fall protection systems, and in particular, to safety harnesses for use in fall protection systems.
Background Information
In fall protection systems, a worker typically wears a safety harness with an attached lifeline. The lifeline is then attached to an anchor, such as a roof anchor. If a worker begins to fall, the lifeline, harness, and anchor, working together, are operable to suspend the fall and bear the worker's weight. In some cases the worker may need to remain in the suspended position for an extended period of time. For example, a worker that falls from the roof of a building may be suspended on the side of the building until he is able to be retrieved.
Many type of safety harnesses are full body harnesses that include shoulder straps and leg straps. The shoulder straps and leg straps are typically formed from woven webbing material such as nylon or other similar materials. The lifeline is usually attached to the back of the harness around where the shoulder straps meet each other.
In the period immediately after a fall, the worker is generally suspended in a vertical orientation, similar to the position the worker would be when standing. When suspended in the vertical position, the force applied by the leg straps to support the worker's weight can be uncomfortable and unhealthy if maintained for an extended period of time. In the suspended position, it is difficult for the worker to reduce the force applied by the leg straps.
These needs and others are met by embodiments of the disclosed concept in which a leg pad for a safety harness includes handles which allow a user to adjust a position of the safety harness and includes elastic cording that biases the handles against leg pad portions.
In accordance with one aspect of the disclosed concept, a leg pad assembly for a safety harness comprises: a pair of leg pad portions structured to receive leg straps of the safety harness; a central pad portion connecting the pair of leg pad portions and structured to receive a seat strap of the safety harness; a pair of handles, wherein each handle is attached to one of the pair of leg pad portions; and elastic cording attached to each of the pair of handles and being structured to bias the pair of handles toward each other and against the pair of leg pad portions.
In accordance with another aspect of the discloses concept, a safety harness comprises: leg straps structured to encircle a user's leg when the safety harness is worn by the user; a seat strap structured to traverse a buttocks area of the user when the safety harness is worn by the user; shoulder straps structured to extend over the user's shoulders when the safety harness is worn by the user; an attachment point attached to the shoulder straps and being structured such that a lifeline may be coupled to the safety harness via the attachment point; and a leg pad assembly including: a pair of leg pad portions structured to receive leg straps of the safety harness; a central pad portion connecting the pair of leg pad portions and structured to receive a seat strap of the safety harness; a pair of handles, wherein each handle is attached to one of the pair of leg pad portions; and elastic cording attached to each of the pair of handles and being structured to bias the pair of handles toward each other and against the pair of leg pad portions.
A full understanding of the disclosed concept can be gained from the following description of the preferred embodiments when read in conjunction with the accompanying drawings in which:
Directional phrases used herein, such as, for example, left, right, front, back, top, bottom and derivatives thereof, relate to the orientation of the elements shown in the drawings and are not limiting upon the claims unless expressly recited therein.
As employed herein, the statement that two or more parts are “coupled” together shall mean that the parts are joined together either directly or joined through one or more intermediate parts.
The shoulder strap assembly 2 is formed from various straps and pads and is structured to extend over the user's shoulders. While one example of a shoulder strap assembly 2 in accordance with the disclosed concept is shown, it will be appreciated that variations of shoulder strap assemblies may be employed without departing from the scope of the disclosed concept.
The belt assembly 4 is also formed from various straps and pads and is structured to extend around the user's waist. While one example of a belt assembly 4 in accordance with the disclosed concept is shown, it will be appreciated that variations of belt assemblies may be employed without departing from the scope of the disclosed concept. Additionally, it will be appreciated that in some embodiments of the disclosed concept, the belt assembly 4 may be omitted. Generally, the shoulder strap assembly 2 and the leg straps 12 are sufficient to support the user. However, the belt assembly 4 adds additional support.
The leg straps 12 are straps that encircle the user's legs. The leg straps 12 attach to the belt assembly 4. In some embodiments the leg straps 12 may attach to the should strap assembly 2 in addition to or instead of the belt assembly 4. The seat strap 14 extends between the leg straps 12 and is positioned so that it extends across the user's buttocks area when the safety harness is worn.
The leg pad assembly 10 is attached to the safety harness 1 over portions of the leg straps 12 and seat strap 14. The leg strap assembly 10 includes leg pad portions 16 and a central pad portion 18. The leg strap assembly 10 also includes handles 30. The handles 30 are exposed via openings in the leg pad portions 16 so that the user wearing the safety harness 1 can grab the handles 30 with their hands.
When a user wearing the safety harness 1 falls and ends up suspended by the safety harness 1, the user will be in a substantially vertical position, as is shown, for example in
As is shown in
The leg pad portions 16 each include an inner leg pad portion 20, an outer leg pad portion 21, and an overlay 22. The inner leg pad portion 20 contacts the user and is disposed between leg strap 12 and the user when the safety harness 1 is worn. The inner and outer leg pad portions 20,21 are disposed on opposite sides of the leg strap 12 so that the leg strap 12 is sandwiched between the inner and outer leg pad portions 20,21. A portion of the seat strap 14 is also sandwiched between the inner and outer leg pad portions 20,21. The leg straps 12 and the seat strap 14 are attached to each other inside the leg pad portions 16, as is shown for example in
The inner and outer leg pad portions 20,21 are also attached to the central pad portion 18. The central pad portion 18 spans between and connects the two leg pad portions 16 and the seat strap 14 passes through the central pad portion 18. The central pad portion 18 may include a padded material such as, without limitation, ballistic nylon.
The overlay 22 is attached to the outer leg pad portion 21 using any suitable method such as, without limitation, stitching. The overlay 22 includes a cutout portion that allows the user to access the handles 30. In some example embodiments of the disclosed concept, the inner and outer leg pad portions 20, 21 include padded material such as, without limitation, ballistic nylon. In some example embodiments of the disclosed concept, the overlay 22 includes a fabric material such as, without limitation Hypalon.
The handles 30 are composed of webbing 31 and a grip portion 32. The webbing 31 forms a loop that passes through the grip portion. The webbing 31 may be composed of a fabric material and the grip portion 32 may be composed of a more resilient material such as a plastic material.
The leg pad assembly 10 further includes elastic cording 40. Referring to
Referring to
The overlay 22 provides an aesthetically pleasing look to the leg pad assembly 10. In some example embodiments of the disclosed concept, the overlay 22 is shaped so that it covers the grommets 23 in the out leg pad portion 21 yet still has a cutout portion that allows the user to access the handles 30. Covering the grommets 23 provides an aesthetically pleasing look and additionally reduces the risk that the handles 30 may become snagged on an object. The bend in the webbing 31 of the handles 30 where it passes through the grommets 23 is an area where there is a high risk of the handles 30 becoming snagged on an object and covering up the area with the overlay 22 reduces the risk. It will also be appreciated by those having ordinary skill in the art that the overlay 22 may be omitted without departing from the scope of the disclosed concept.
It will be appreciated by those having ordinary skill in the art that the leg pad assembly 10 may be manufactured and attached to the safety harness 1 around the time when the safety harness 1 is manufactured. However, it will also be appreciated by those having ordinary skill in the art that the leg pad assembly 10 may be manufactured independent of the safety harness 1 and attached to the safety harness 1 at a later time. For example, the leg pad assembly 10 may be attached to an existing safety harness as an upgrade for the safety harness.
While specific embodiments of the disclosed concept have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the disclosed concept which is to be given the full breadth of the claims appended and any and all equivalents thereof.
