Abstract
A housing for a self-retracting lifeline includes an outer area disposed on a portion of a first side of the housing, the outer area being planar, a label area stepped down from the outer area, an outer perimeter of the label area corresponding to an inner perimeter of the outer area, and a number of protruding members disposed at least on a portion of the first side of the housing and being stepped up from the outer area.
Description
BACKGROUND
Field

The disclosed concept relates generally to fall protection systems, and in particular, to a housing for a self-retracting lifeline used in fall protection systems.


Background Information

In fall protection systems, a worker typically wears a harness. In some systems, a lifeline is attached to an attachment point on the harness and to an anchor point on a building, connecting the worker to the anchor point. In the case of a fall, the lifeline will arrest the fall, preventing injury to the worker. There are numerous in types of lifelines, harnesses, and types of anchor points used, but the principle of arresting the fall is generally similar.


One type of lifeline is a self-retracting lifeline. A self-retracting lifeline typically includes a retracting device into which the lifeline is retracted. The lifeline can be pulled out of the retracting device under normal forces, such as a worker walking away from the anchor point. This allows the lifeline to remain under some tension. The retracting device also includes a braking mechanism. When the lifeline is quickly pulled out of the retracting device, such as when a fall occurs, the braking mechanism engages to slow and stop the lifeline from being pulled out of the retracting device and, in this manner, arrests the fall of the worker.


In transport and in use, a self-retracting lifeline is can become damaged due to dropped, bumped against objects, subjected to various weather conditions, or any other hazards that may arise. In particular, the retracting device should be protected because, if it were to become damaged, it may not operate properly in the case of a fall. The retracting device is typically contained in a housing, but there remains room for improvement in housings for self-retracting lifelines.


SUMMARY

These needs and others are met by embodiments of the disclosed concept in which a housing for a self-retracting lifeline includes one or more protruding members.


In accordance with one aspect of the disclosed concept, a housing for a self-retracting lifeline comprises an outer area disposed on a portion of a first side of the housing, the outer area being planar; a label area stepped down from the outer area, an outer perimeter of the label area corresponding to an inner perimeter of the outer area; and a number of protruding members disposed at least on a portion of the first side of the housing and being stepped up from the outer area.


In accordance with on aspect of the disclosed concept, a self-retracting lifeline comprises: a housing including: an outer area disposed on a portion of a first side of the housing, the outer area being planar; a label area stepped down from the outer area, an outer perimeter of the label area corresponding to an inner perimeter of the outer area; and a number of protruding members disposed at least on a portion of the first side of the housing and being stepped up from the outer area; a retractable device disposed within the housing; a first attachment mechanism attached proximate a top of the housing; a lifeline extending from the housing; an energy absorber attached to the lifeline; and a second attachment mechanism attached to the energy absorber.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

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.


In accordance with some example embodiments of the disclosed concept, a housing for a self-retracting lifeline. In some example embodiments, the housing includes a label area and multiple step-downs in the housing protect the label area. Some features that create the multiple step-downs also protect the integrity of the housing. In some example embodiments of the disclosed concept, the housing includes a retractable handle that eases carrying of the self-retracting lifeline. Some example embodiments of the disclosed concept will be described in more detail herein.



FIG. 1 is an isometric view of a self-retracting lifeline including a housing 100 in accordance with an example embodiment of the disclosed concept. FIG. 2 is a front view of the self-retracting lifeline of FIG. 1, FIG. 3 is a left-side view of the self-retracting lifeline of FIG. 1, FIG. 4 is a right-side view of the self-retracting lifeline of FIG. 1, FIG. 5 is a top view of the self-retracting lifeline of FIG. 1, and FIG. 6 is a bottom view of the self-retracting lifeline of FIG. 1. The self-retracting lifeline includes the housing 100, an attachment ring 200 for attaching to an attachment point on a harness, an energy absorber 202, and a hook 204 for attaching to an anchor point. A retracting device may be disposed within the housing 100 and includes a lifeline attached to the energy absorber.


The housing 100 includes a two-part body formed from a first body part 102 and a second body part 104. The first body part 102 and the second body 104 form halves of the housing 100 and attach together to form the housing 100. The housing 100 includes a number of features. One such feature is a planar outer area 106 formed on sides of the housing 100. Stepped down from the outer area 106 is a planar label area 114. The outer area 106 surrounds the label area 114. The extents of the label area 114 are defined by a step which steps up to the outer area 106. In the example embodiment shown in FIG. 1, the perimeter of the label area 114 has an arc shape on one side. Moving toward the opposite side of the label area 114 are angled perimeter sections followed by substantially parallel perimeter sections, as are shown in FIG. 1. The label area 114 is wider on the side of the arc shaped perimeter section and narrower on the opposite side. However, it will be appreciated that modifications may be made to the shape of the perimeter of the label area 114 without departing from the scope of the disclosed concept. Stepping down the label area 114 from the outer area 106 provides protection for the label area 114. Due to its protection, the label area 114 is a useful area for placing a label, such as a label including brand information, safety information, or any other type of information. The label will be protected from being scuffed or otherwise damaged by general impacts on the housing 100.


Another feature a first protruding member 108. The first protruding member 108 is located on a lower part of the housing 108 and is stepped up from the outer area 106. The first protruding member 108 extends from a portion of one side of the housing 100, across a bottom of the housing 100, and into a portion of the opposite side of the housing 100. The first protruding member 108 may have a portion of its perimeter correspond in shape to a portion of the perimeter of the label area 114. By being stepped up from the outer area 106, the first protruding member 108 may provide protection from impacts to the housing 100. In some example embodiments, the first protruding member 108 may be part of the first and second body parts 102,104. For example, half of the first protruding member may be part of the first body part 102 and the other half of the first protruding member 108 may be part of the second body part 104. In an example embodiment, the first body part 102 and half of the first protruding member 108 may be a unitary piece formed together, for example and without limitation, in a molding process. Similarly, the second body part 104 and the other half of the first protruding member 108 may be a unitary piece. When the first and second body parts 102,104 are brought together to form the housing 100, the halves of the first protruding member 108 may abut together to form a continuous protrusion on the housing 100.


Second protruding members 110 are another feature of the housing 100. Second protruding members 110 being on opposite sides of the housing 100 and extend across front edges of the housing 100. Second protruding members 110 are also stepped up from outer area 106. Second protruding members 110 may each have an arc shaped edge that corresponds in shape to a portion of the arc shaped perimeter section of the label area 114. Protruding members 110 each have a body section disposed on sides of the housing 110 and prong sections that extend across the front edge of the housing 100. One second protruding member 110 may be part of the first body part 102 and the other second protruding member 110 may be part of the second part 104. There may be a space between the second protruding members 110 on the front side of the housing 100 when the first and second parts 102,104 are brought together to form the housing. The second protruding members 110 provide protection to the housing 100 and, in particular, to front edges of the housing 100 that may be susceptible to impacts.


A third protruding member 112 is another feature of the housing 100. The third protruding member 112 begins on one side of the housing 100, extends across the top of the housing 100, and ends on the other side of the housing 100. The third protruding member 112 includes an opening on the top side of the housing 100. The opening allows a point where the attachment ring 200 may be connected. The third protruding member 112 is stepped up from the outer area 106 and extends along a portion of upper edges of the housing 100. The third protruding member 112 also provides protection against impacts to the housing 100.


Fourth and fifth protruding members 116,118 are also features of the housing 100. Fourth and fifth protruding members 116,118 are disposed on a back side of the housing 100. Fourth and fifth protruding members 116,118 are stepped up portions that may be spaced apart from each other. Fourth and fifth protruding members 116,118 may extend across an area with the first and second body parts 102,104 meet. In some example embodiments, fourth and fifth protruding members 116,118 may have tapered elongated shapes. However, it will be understood that other shapes may be employed without departing from the scope of the disclosed concept. Fourth and fifth protruding members 116,118 may protect the housing 100 from impacts as well as provide structural support.


The first through third protruding members 108,110,112 along with the outer area 106 provide a multi-stepped geometry that protects the label area 114. For example, the outer area 106 is stepped up from the label area 114 and the first through third protruding members 108,110,112 are stepped up from the outer area 106, which creates multiple steps up from the label area 114. This multi-stepped protection provides protection for any label applied in the label area 114 and reduces the chances of a label being scuffed or otherwise damaged by impacts to the housing 100. The multi-stepped geometry also provide general protection to the housing 100 and structural support to the housing 100, making is less likely that impacts or other wear and tear will compromise the integrity of the housing 100.


In some example embodiments, the first through fifth protruding members 108,110,112,114,116 are integrally formed as parts of the first and second body parts 102,104, for example and without limitation, by molding. This integral construction provides structural support. However, it will be appreciated that in some example embodiments, one or more of the first through fifth protruding members 108,110,112,114,116 may not be integral with the first and second body parts 102,104, and may instead be attached to the first and second body parts 102,104.


In some example embodiments, the housing 100 has a roughly cylindrical shape. However, it will be appreciated that variations may be made to the shape of the housing 100 without departing from the scope of the disclosed concept. It will also be appreciated that variations to the shapes of any other features of the housing 100 may be modified without departing from the scope of the disclosed concept. It will further be appreciated that one or more features may be added, removed, or modified without departing from the scope of the disclosed concept. Another example embodiment of the disclosed concept will also be described herein.

A retracting device may be disposed within the housing 400 and includes a lifeline attached to the energy absorber.


The housing 300 includes a two-part body formed from a first body part 302 and a second body part 304. The first body part 302 and the second body 304 form halves of the housing 300 and attach together to form the housing 300. The housing 300 includes a number of features. One such feature is a planar outer area 306 formed on sides of the housing 300. Stepped down from the outer area 306 is a planar label area 314. The outer area 306 surrounds the label area 314. The extents of the label area 314 are defined by a step which steps up to the outer area 306. In the example embodiment shown in FIG. 7, the perimeter of the label area 314 has an arc shape on one side. Moving toward the opposite side of the label area 314 are angled perimeter sections followed by substantially parallel perimeter sections, as are shown in FIG. 7. The label area 314 is wider on the side of the arc shaped perimeter section and narrower on the opposite side. However, it will be appreciated that modifications may be made to the shape of the perimeter of the label area 314 without departing from the scope of the disclosed concept. Stepping down the label area 314 from the outer area 106 provides protection for the label area 314. Due to its protection, the label area 314 is a useful area for placing a label, such as a label including brand information, safety information, or any other type of information. The label will be protected from being scuffed or otherwise damaged by general impacts on the housing 300.


The housing 300 also includes a first protruding member 308. The first protruding member 308 is located on a lower part of the housing 308 and is stepped up from the outer area 306. The first protruding member 308 extends from a portion of one side of the housing 300, across a bottom of the housing 300, and into a portion of the opposite side of the housing 300. The first protruding member 308 may have a portion of its perimeter correspond in shape to a portion of the perimeter of the label area 314. By being stepped up from the outer area 306, the first protruding member 308 may provide protection from impacts to the housing 300. In some example embodiments, the first protruding member 308 may be part of the first and second body parts 302,304. For example, half of the first protruding member may be part of the first body part 302 and the other half of the first protruding member 308 may be part of the second body part 304. In an example embodiment, the first body part 302 and half of the first protruding member 308 may be a unitary piece formed together, for example and without limitation, in a molding process. Similarly, the second body part 304 and the other half of the first protruding member 308 may be a unitary piece. When the first and second body parts 302,304 are brought together to form the housing 300, the halves of the first protruding member 308 may abut together to form a continuous protrusion on the housing 300.


The housing 300 also includes second and third protruding members 310,311. The second and third protruding members 310,311 are disposed on a front side of the housing 300 and extend across a portion of the front edges of the housing 300 onto sides of the housing 300. In an example embodiment, the third protruding member 311 is longer than the second protruding member 310. However, it will be appreciated that the lengths of the second and third protruding members 310,311 may be varied without departing from the scope of the disclosed concept. In an example embodiment, ends of the third protruding member 311 are stepped up from the outer area 306. In some example embodiments, the second protruding member 310 may also be stepped up from the outer area 306. In the example embodiment shown in FIG. 7 though, the second protruding member 310 does not extend into the outer area 306 while the third protruding member 311 does. In some example embodiments, the second and third protruding members 310,311 may be part of the first and second body parts 302,304. For example, half of the second and third protruding members 310,311 may be part of the first body part 302 and the other half of the second and third protruding member 310,311 may be part of the second body part 304. In an example embodiment, the first body part 302 and half of the second and third protruding members 310,311 may be a unitary piece formed together, for example and without limitation, in a molding process. Similarly, the second body part 304 and the other half of the second and third protruding members 310,311 may be a unitary piece. When the first and second body parts 302,304 are brought together to form the housing 300, the halves of the second and third protruding members 310,311 may abut together to form a continuous protrusion on the housing 300. The second and third protruding members 310,311 may provide protection to front edges of the housing 300 from impacts.


The housing 300 further includes a fourth protruding member 312. The fourth protruding member 312 begins on one side of the housing 300, extends across the top of the housing 300, and ends on the other side of the housing 300. The fourth protruding member 312 includes an opening on the top side of the housing 300. The opening allows a point where the attachment ring 400 may be connected. The fourth protruding member 312 is stepped up from the outer area 106 and extends along a portion of upper edges of the housing 300. The fourth protruding member 312 also provides protection against impacts to the housing 300. The fourth protruding member 312 may also have a cutout section where an end of a retractable handle 316 may be placed. The fourth protruding member 312 may be attached to the first and second body parts 302,304, rather than being formed as a unitary piece with them. However, it will be appreciated that in some example embodiments, the fourth protruding member 312 may be formed as a unitary piece with the first and second body parts 302,304.


The housing 300 also includes a retractable handle 316. The retractable handle 316 may attach at a top portion of the housing 300 and extend along a back side of the housing 300. The retractable handle 316 may have a shape that substantially corresponds to a shape of the back side of the housing 300. The retractable handle 316 may have a retracted position and a non-retracted position. One end of the retractable handle 316 is attached at a top portion of the housing and the opposite end of the retractable handle 316 is not attached. In the non-retracted position, the unattached end of the retractable handle 316 is further from than back side of the housing 300 than when the retractable handle 316 is in the retracted position. In some example embodiments, the retractable handle 316 is biased toward the retracted position. By having an end of the retractable handle 316 unattached, a carabiner or other attachment device cannot be attached to the retractable handle 316 and the retractable handle 316 will not be mistaken for an attachment point by a worker. However, the retractable handle 316 does allow a worker to more easily carry the self-retracting lifeline.


The first, third, and fourth protruding members 308,311,312 along with the outer area 306 provide a multi-stepped geometry that protects the label area 314. For example, the outer area 306 is stepped up from the label area 314 and the first, third, and fourth protruding members 308,311,312 are stepped up from the outer area 306, which creates multiple steps up from the label area 314. This multi-stepped protection provides protection for any label applied in the label area 314 and reduces the chances of a label being scuffed or otherwise damaged by impacts to the housing 300. The multi-stepped geometry also provide general protection to the housing 300 and structural support to the housing 300, making is less likely that impacts or other wear and tear will compromise the integrity of the housing 300.


In some example embodiments, the first through fourth protruding members 308,310,311,312 are integrally formed as parts of the first and second body parts 302,304, for example and without limitation, by molding. This integral construction provides structural support. However, it will be appreciated that in some example embodiments, one or more of the first through fourth protruding members 308,310,311,312 may not be integral with the first and second body parts 302,304, and may instead be attached to the first and second body parts 302,304. In an example embodiment, the first through third protruding members 308,310,311 are integrally formed with the first and second body parts 302,304 and the fourth protruding member 312 is attached to the first and second body parts 302,304.


In some example embodiments, the housing 300 has a roughly protruded cylindrical shape in which a central part of the housing 300 is wider than an outer part of the housing 300. However, it will be appreciated that variations may be made to the shape of the housing 300 without departing from the scope of the disclosed concept. It will also be appreciated that variations to the shapes of any other features of the housing 300 may be modified without departing from the scope of the disclosed concept. It will further be appreciated that one or more features may be added, removed, or modified without departing from the scope of the disclosed concept.
