Description

BACKGROUND

Fall protection equipment is commonly used to reduce a likelihood of a fall and/or injuries associated with a fall, particularly by users who perform tasks at heights or are at risk of falling. Generally, lifelines or lanyards typically interconnect anchorage structures and safety harnesses donned by users. The lifelines or lanyards allow the users to move and perform tasks while being connected to the anchorage structures. Should a user fall, the lifeline or lanyard limits the distance the user falls.

A user often connects a lifeline or a lanyard to a dorsal D-ring positioned on the back of the user's safety harness. To connect and disconnect the lifeline or lanyard, it may be difficult if the D-ring is in a downward position relative to the user. There are other positions on the safety harness where a positionable D-ring would be useful.

For the reasons stated above and for other reasons stated below, which will become apparent to those skilled in the art upon reading and understanding the present specification, there is a need in the art for a positionable D-ring assembly.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration embodiments in which the disclosure may be practiced. It is to be understood that other embodiments may be utilized and mechanical changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense.

Embodiments of the disclosure provide a positionable connector assembly.

An example embodiment is illustrated in FIGS. 1-2. A positionable connector assembly 100 includes a base 101 to which a connector 116 is connected. Generally, the positionable connector assembly 100 could be connected to straps of a safety harness proximate a user's back or other desired locations. It is recognized that any suitable base could be used and any suitable connector such as a D-ring could be used. Throughout the description, the terms connector and D-ring are interchangeable. For example, the base could have other configurations providing other ways to route straps of a safety harness and to connect to the connector, and the connector could have other configurations. Further, the positionable connector assembly could be used in a variety of locations on the safety harness.

The base 101 is generally U-shaped and includes a first side portion 102 and a second side portion 103 connected proximate the top by a first bar portion 104 and proximate the bottom by a second bar portion 105 to form an opening 106. A receiver 107 is connected to the first side portion 102 and the second side portion 103 between the first bar portion 104 and the second bar portion 105, and the receiver 107 including a cylindrical portion through which a receiver bore 108 extends. Extending upward from the first side portion 102 proximate the first bar portion 104 is a first extension 109, and extending upward from the second side portion 103 proximate the first bar portion 104 is a second extension 111. The first extension 109 includes a first aperture 110, the second extension includes a second aperture 112, and the first and second apertures 110 and 112 align. The base 101 is shown in FIG. 3. Although any suitable material may be used, preferably a light weight metal, such as aluminum, may be used.

A first strap 150 of a safety harness is routed about the first bar portion 104 to form the shoulder straps of the safety harness, and a second strap 151 of a safety harness is routed about the second bar portion 105 to form the back straps of the safety harness. This is shown in FIG. 10.

As shown in FIGS. 4-8, the connector 116 includes a ring portion 117 and a connector portion 119. The ring portion 117 is generally round, although any suitable configuration would be acceptable, and forms an opening 118. The bottom of the ring portion 117 is connected to the connector portion 119. Preferably, the ring portion 117 and the connector portion 119 are integral, but they could be two separate components operatively connected to one another. Although any suitable material may be used, preferably a light weight metal, such as aluminum, may be used.

The connector portion 119 is generally tubular shaped and includes an intermediate portion 122 interconnecting a first end portion 120 and a second end portion 121. A bore 123 extends longitudinally through the connector portion 119. The first end portion 120 includes a first receiving portion 120a, which is a recessed portion larger than the bore 123 but smaller than the outer diameter of the first end portion 120, and the second end portion 121 includes a second receiving portion 121a, which is a recessed portion larger than the bore 123 but smaller than the outer diameter of the second end portion 121. The first receiving portion 120a is configured and arranged to receive a friction member 136, and the second receiving portion 121a is configured and arranged to receive a biasing member 141. Alternatively, the friction member 136 and the biasing member 141 could be received within the first extension 109 and the second extension 111.

The friction member 136 is generally disc shaped and includes an aperture 137 aligning with the bore 123. Although the friction member 136 is generally disc shaped, it is recognized that any suitable friction member could be used. The friction member 136 could be made of any suitable material that provides friction such as but not limited to elastomers, composite materials, and textured materials.

The biasing member 141 is preferably a coil spring including a bore 142 aligning with the bore 123. The coil spring could include waves, which assist in making the coil spring more compact. The biasing member 141 is shown in FIG. 9. It is recognized that any suitable biasing member such as but not limited to a compression spring, a leaf spring, and a magnet could be used.

The connector portion 119, in which the friction member 136 and the biasing member 141 are positioned, is configured and arranged to be received between the first extension 109 and the second extension 111 of the base 101. The bore 123 of the connector portion 119, the aperture 137 of the friction member 136, and the bore 142 of the biasing member 141 align with the first aperture 110 and the second aperture 112, and a fastener 128 extends therethrough to connect the connector portion 119 to the base 101.

The fastener 128 includes a shaft 129 to which a head 130 is operatively connected proximate one end. A distal end 131 includes a detent 132 configured and arranged to receive a retaining member 146. As illustrated in FIG. 1, the first extension 109 and the second extension 111 are captured between the head 130 and the retaining member 146. The connector 116 is pivotable about and movable along the fastener 128 relative to the base 101.

When thus assembled, the biasing member exerts force between the base and the connector, biasing the connector toward the friction member. In this example embodiment, the biasing member 141 pushes against the second extension 111 and the second end portion 121 and, because the connector 116 is movable along the fastener 128, the biasing member 141 biases the connector 116 away from the second extension 111 and toward the friction member 136. The friction member 136 is positioned between and contacts the first extension 109 and the first end portion 120 thereby providing frictional resistance to pivoting of the connector 116 relative to the base 101 when the connector 116 is biased toward the friction member 136.

To reposition the connector 116 relative to the base 101 in any one of several desired positions, the connector 116 may be manually pivoted about the fastener 128. During repositioning, the force of the biasing member 141 is at least partially overcome thereby reducing the amount of friction on the connector 116 and allowing the connector 116 to be pivoted into a desired position. Once in the desired position, regardless whether it is an upward or downward position relative to the user, the connector remains in that position until it is repositioned either manually or during use.

If the positionable connector assembly 100 is positioned proximate a user's back, to connect a safety device such as a lifeline or a lanyard to the connector 116, the user could position the connector 116 into a desired position either before or after donning the safety harness. In the desired position, the user more easily connects the safety device to the connector 116. During use, when a safety device is connected to the connector 116, the safety device could pivot and reposition the connector 116 relative to the base 101.
