ABSTRACT:
BACKGROUND OF THE INVENTION
(1) Field of the Invention
This invention relates to a harness for human wear, and is directed more particularly to a harness for use as an emergency egress/descent harness and as a safety restraint.
(2) Description of the Prior Art
Harnesses available for egress/descent, and as safety restraints, typically are either full body harnesses or single-strap belts having a load ring thereon. The former are not in favor among sport climbers, fire fighters, bridge workers, special weapons and tactics teams, and the like, because of the inconvenience of donning the harness and the interference of the harness with the other gear or weapons carried by the wearer. Those who have need of such devices often elect not to carry them, taking a chance that an emergency situation requiring their use will not arise. The latter are preferred because of the ease of use and lack of interference with other equipment borne by the wearer, and because since a belt is customarily worn anyhow, one need not be carried and donned in emergency situations. However, putting a load ring on a belt at any point causes the body weight to be supported only at the waist.
Accordingly, there is a need for a belt which encounters little resistance to wear, and which, when circumstances warrant, is readily converted to a harness affording waist and leg support.
SUMMARY OF THE INVENTION
In view thereof, an object of the invention is to provide a harness for human wear which in one mode constitutes a belt for wear around the waist of a human, and, in another mode constitutes a harness providing waist and leg support.
With the above and other objects in view, as will hereinafter appear, a feature of the present invention is the provision of a harness for human wear comprising an elongated belt for encircling a waist of a wearer. A first strap is fixed to the belt and is extendible transversely of the belt with a longer portion of the first strap extending from a lower edge of the belt and a shorter portion of the first strap extending from an upper edge of the belt, the first strap having loops at each end thereof. A second strap is fixed to the belt and is extendible transversely of the belt with a longer portion of the second strap extending from the lower edge of the belt and a shorter portion of the second strap extending from the upper edge of the belt, the second strap having loops at each end thereof. First and second ends of the belt are connectable together, and the loops are adapted for disposal at a generally common point for engagement with a single connector member.
In accordance with a further feature of the invention, there is provided a harness for human wear comprising an elongated belt for encircling a waist of a wearer. A first strap is fixed to the belt and is extendible transversely of the belt, the first strap extending from a lower edge of the belt and having first connector means at a free end thereof. A second strap is fixed to the belt and is extendible transversely of the belt, the second strap extending from the lower edge of the belt and having second connector means at a free end thereof. The strap end connector means are adapted for disposal at a generally common point for engagement with a single loop member mounted on the belt.
The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims. It will be understood that the particular devices embodying the invention are shown by way of illustration only and not as limitations of the invention. The principles and features of this invention may be employed in various and numerous embodiments without departing from the scope of the invention.
