## Background
RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Patent Application 61/300,006 filed Jan. 31, 2010 for the same inventor.


FIELD OF THE INVENTION
This invention relates to a hanger hook for holding radio headsets in emergency vehicles. The invention further relates to a hanger hook adapted for retaining various types of strap, line, cable, cord, conduit, or filament in diverse applications.
BACKGROUND
New requirements mandate securing equipment in case of an accident in Emergency Vehicles like Fire Trucks and Ambulances: NFPA 1901-2009 states:
“14.1.11.2 All equipment not required to be used during an emergency response, with the exception of SCBA units, shall not be mounted in a driving or crew area unless it is contained in a fully enclosed and latched compartment capable of containing the contents when a 9 G force is applied in the longitudinal axis of the vehicle or a 3 G force is applied in any other direction, or the equipment is mounted in a bracket(s) that can contain the equipment when the equipment is subjected to those same forces.”
Currently available simple hanger hooks are used to hold equipment but do not secure the equipment against a vertical 3 G force or horizontal 9 G force. Latching mechanisms and compartments increase the time it takes for emergency crew members to access their radio headsets, and so are not preferred.
U.S. Pat. No. D468,192 shows a single hook member that bends to the left as it curves back to the stem, without any retainer or collinear annular fastener opening. U.S. Pat. No. D474,105 also shows a single hook member that bends to the left as it curves back to the stem, without any retainer or collinear annular fastener opening. U.S. Pat. No. D282,904 shows a flat simple hook with a safety latch. U.S. Pat. No. D380,665 shows a safety hook that multiply bent. U.S. Pat. No. D401,840 shows a double hook having a top hook that is not a retainer above a collinear fastener opening and a bottom hook below the collinear fastener opening that partially obstructs frontal access to the fastener opening. U.S. Pat. No. D408,723 shows a single hook with collinear fastener openings with frontal access to the fastener opening partially obstructed by the hook end. U.S. Pat. No. D584,134 shows a hook rotated ninety degrees from a plane of an annular fastener opening.
Therefore, a need exists for a hanger hook that can retain equipment against a vertical 3 G force and a horizontal 9 G force. A need also exists for a hanger hook that enables rapid access to the retained emergency equipment. A need exists for a hanger hook that is easy to install. A need exists for a hanger hook that can be manufactured in various sizes and strengths for retaining equipments of various masses. A need exists for a hanger hook design that can be adapted to retaining various types of strap, line, cable, cord, conduit, or filament in widely diverse applications.

SUMMARY OF THE INVENTION
In accordance with a preferred embodiment hereof, the present invention provides a hanger hook with upper and lower members (retainer and support, respectively) integral with an fastener receiver portion. The fastener receiver portion is annular, with the central opening sized to receive a fastener, such as a bolt. The thickness and the radial extent of the annular fastener receiver portion are dimensioned to be sufficient to endure a 9G force for the particular maximum mass to be retained, given the material used for the hanger hook. In preferred installed operation, the annular fastener receiver portion is secured to an interior surface or member of an emergency vehicle with a fastener through the central opening of the annular fastener receiver portion. The lower member extends from the bottom of the annular fastener receiver portion downward (in the drawings and in some installed operations) outward (relative to the surface of installation), and to the viewer's left via a first elbow portion, diagonally upward, outward, and to the viewer's left via a first straight portion, upward and inward by a second elbow portion, and upward, inward, and to the right by a second straight portion to a tip, thereby forming a support. The upper member extends from the top of the annular fastener receiver portion via a third elbow outward, downward, and to the right, and then by a third straight portion outward, downward, and to the right to a tip to form a retainer. The tip of the retainer is lower than the tip of the support. The tip of the support is preferably higher than the annular fastener receiver portion. The support is angled to the left and the retainer is angled to the right to provide clear access to the opening of the annular fastener receiver portion, thus assisting installation. In a particular embodiment, the directions may be reversed.

DETAILED DESCRIPTION OF THE BEST MODES AND PREFERRED EMBODIMENTS OF THE INVENTION
FIG. 1 is a front elevation view illustrating an exemplary hanger hook 100, according to a preferred embodiment of the present invention. The present invention provides a hanger hook 100 with upper and lower members 128, 126 integral with an annular fastener receiver portion 102. The fastener receiver portion 102 is annular, with the central opening 104 sized to receive a fastener, such as a bolt 2104 (see FIG. 22). The thickness and the radial extent of the annular fastener receiver portion 102 are dimensioned to be sufficient to endure a 9 G force for the particular maximum mass to be retained, given the material used for the hanger hook 100. In installed operation, the annular fastener receiver portion 102 is secured to an interior surface 2102 or member of a vehicle, such as an emergency vehicle, with a fastener 2108 through the central opening 104.
The following description refers to directions based on vertical installation on a vertical surface. It should be understood the hanger hook 100 is not limited to vertical installation nor to installation on a vertical surface. Hanger hook has an axis of radial symmetry 103 (out of the page, in this view) and a linear axis 105 that aligns with the center of central opening 104 and the two opposing edges 111 and 113 from which the retainer 128 and the support 126 extend. The lower member 126, or support 126, extends from the bottom edge 111 as extension 106 of the annular fastener receiver portion 102 downward (in the drawings and in some installed operations) outward (relative to the surface of installation 2102), and to the left (as viewed) via a first elbow portion 108; diagonally upward, outward, and to the left via a first straight, or linear, portion 110; upward and inward by a second elbow portion 112; and upward, inward, and to the right by a second linear portion 114 to a first tip 116, thereby forming a support 126. The upper member 128, or retainer 128, extends from the top edge 113 as extension 118 of the annular fastener receiver portion 102; via a third elbow 120 outward, downward, and to the right; and then by a third linear portion 122 outward, downward, and to the right to a second tip 124 to form a retainer 128. The second tip 124 of the retainer 128 is lower than the first tip 116 of the support 126. The components of the vertical (in this view) extents of the retainer 128 and the support 126 that are parallel to the linear axis overlap. Both the retainer 128 and the support 126 are angled away from a plane defined by said axis of radial symmetry 103 and the linear axis 105 by angles of equal magnitude and opposite direction, as will be further discussed below in regard to FIG. 5. The support 126 is angled to the left and the retainer 128 is angled to the right to provide clear access to the opening 104 of the annular fastener receiver portion 102 along the radial axis 103, thus assisting installation. In a particular embodiment, the directions may be reversed: the present invention includes the mirror image of hanger hook 100. The first tip 116 of the support 126 preferably extends beyond the top edge 113 of the annular fastener receiver portion 102, as shown. The second tip 124 of the retainer 128 preferably extends beyond the top edge 113 of the annular fastener receiver portion 102, as shown.
The hanger hook 100 may be made of various materials. For emergency equipment retention, rigid metals, such as steel, are preferred. In other applications, such as retaining telephone wires or computer cables in an office, a rigid plastic may be preferred. Those of skill in the art, enlightened by the present disclosure, will appreciate the diverse applications to which the present invention may be applied and the requirements for the strength of materials for each particular application. In a particular application, the materials may be substantially resilient. In a particular embodiment, the hanger hook 100 may be made in two parts, including a top member 128 with a first annular fastener receiver portion 102 and a lower member 126 with a second annular fastener receiver portion 102, where first and second annular fastener receiver portions 102 overlay and interlock in alignment and the hanger hook 100 is assembled during installation.
Variation of shape of the external perimeter of the annular fastener receiver portion 102 and of the cross-sectional shape of the retainer 128 and the support 126 is within the scope of the invention. The angular extent to which the retainer 128 and support 126 diverge from the vertical (as illustrated) is variable over various embodiments, within the constraints that direct (axially aligned) frontal tool access (i.e., for a nut driver or screw driver) be provided to opening 104 and that the hanger hook 100 still retain the illustrated functionality of preventing a retained strap 1504 (see FIG. 15) from escaping under a 9 G load.
In an alternate embodiment for ceiling attachment, the annular fastener receiver portion 102 may be in the position of elbow 120.
FIG. 2 is a rear elevation view illustrating an exemplary hanger hook 100, according to the preferred embodiment of FIG. 1. In FIGS. 1-6, the lines separating the reference-numbered portions of support 126 and retainer 128 do not indicate discrete parts. The hanger hook 100 is preferably made of one piece.
FIG. 3 is a front-top perspective view illustrating an exemplary hanger hook 100, according to the preferred embodiment of FIG. 1. The hanger hook 100 may be made in various sizes and materials. For example, a very small hanger hook 100 for retaining wires or strap cable in place inside a personal computer may be made of an electrically insulating material, such as plastic.
FIG. 4 is a left elevation view illustrating an exemplary hanger hook 100, according to the preferred embodiment of FIG. 1. Extensions 118 and 106 from annular fastener receiver portion 102 may be of various lengths, adapted to the requirements of the equipment to be retained. Annular fastener receiver portion 102 may be thicker or thinner than the illustrative example, depending on the mass of the equipment to be retained. When installed in an emergency vehicle, the axis of radial symmetry 103 of annular fastener receiver 102 is preferably perpendicular to the long axis of the vehicle and the divergence of the support 126 from such axis is preferably toward the rear of the vehicle. However, hanger hook 100 may be installed in various orientations.
FIG. 5 is a bottom plan view illustrating an exemplary hanger hook 100, according to the preferred embodiment of FIG. 1. In a particular embodiment, linear portions 122 and 110 may be curved, within the constraint that retainer tip 124 is lower than support tip 116 in an installed position (FIG. 1), and that the support 126 and the retainer 128 diverge to enable tool access to opening 104 for fastening the hanger hook 100 to an interior surface 2102 or structural member of a vehicle, or to other useful surface or structure 2102.
From FIG. 5, it can be seen that the elements of the retainer 128 lie in a retainer plane 502 and that the configuration of the elbow 120 is responsible for angling the retainer 128 away from the midline plane defined by linear axis 105 and the axis of radial symmetry 103. In FIG. 5, the axis of radial symmetry 103 is collinear with the edge of the midline plane. It can also be seen that the elements of the support 126 lie in a support plane 504 and that the configuration of the elbow 108 is responsible for angling the support 126 away from the midline plane.
The angle α outward from the midline plane made by the support 126 may be clearly seen in this view. The angle β outward from the midline plane to the retainer 128 may also be clearly seen in this view. Preferably a and β are of equal magnitude and of opposite direction. Most preferably, a and β are 17.5 degrees. In various alternate embodiments, the angles α and β may differ, within the boundaries of continuing to hold equipment against 9 G accelerations in the horizontal plane and 3 G accelerations in the vertical plane.
FIG. 6 is a front-top perspective view illustrating an exemplary hanger hook 100, according to the preferred embodiment of FIG. 1. In a particular alternate embodiment, hanger hook 100 may have a coating, such as, without limitation, an anodized coating, a polymeric coating, or a ceramic coating. In an appropriate alternate embodiment, first and second tips 116 and 124 may be padded. Preferably, first and second tips 116 and 124 are beveled, as shown.
In an alternate embodiment, annular fastener receiver portion 102 may replace elbow 120 and a linear portion may replace the original annular fastener receiver portion 102 for fastening the hanger hook to a ceiling. In another alternate embodiment, annular fastener receiver portion 102 may replace elbow 108 and a linear portion may replace the original annular fastener receiver portion 102 for fastening the hanger hook to a floor.
FIG. 7 is a rear-side perspective view illustrating an exemplary prior art hook 700. Annular attachment portion 702 has central opening 704 to receive a fastener. First straight portion 706 extends downwardly from annular attachment portion 702 to first elbow 708, which curves directly outward from an attachment surface and upward. Second straight portion 710 extends upward and outward from first elbow 708 to second elbow 712, which curves upward and inward. Third straight portion 714 extends upward and inward to form exemplary prior art hook 700. Exemplary prior art hook 700 has no retainer 128, and so cannot retain equipment undergoing an upward 3 G force.
Safety hooks have a biased-closed hinged member (not shown) between the joint of annular attachment portion 702 and straight portion 706, which extends in the biased condition to straight portion 714. Safety hooks require two actions to allow retrieval of equipment: first to open the hinged member and second to retrieve the equipment. The retrieval of equipment from a safety hook often requires two hands, whereas equipment can be retrieved from the hanger hook 100 with one hand making a single twisting motion.
FIG. 8 is another rear-side perspective view illustrating the exemplary prior art hook 700 of FIG. 7.
FIG. 9 is yet another rear-side perspective view illustrating the exemplary prior art hook 700 of FIG. 7.
FIG. 10 is a left side elevation view illustrating the exemplary prior art hook 700 of FIG. 7. The vertical extent of straight portion 714 must be limited to avoid obstructing direct tool access to opening 704. Compare FIG. 4 with FIG. 10.
FIG. 11 is a top plan view illustrating the exemplary prior art hook 700 of FIG. 7. Exemplary prior art hook 700 extends perpendicularly from the vertical surface to which it is attached. Because of the lack of a retainer 128, the orientations in which exemplary prior art hook 700 will function properly are much more limited than hanger hook 100.
FIG. 12 is a rear elevation view illustrating the exemplary prior art hook 700 of FIG. 7. FIGS. 12, 13, and 14 are provided for completeness.
FIG. 13 is a front elevation view illustrating the exemplary prior art hook 700 of FIG. 7.
FIG. 14 is a bottom plan view illustrating the exemplary prior art hook 700 of FIG. 7.
FIG. 15 includes front elevation views illustrating, for comparison, the prior art hook 700 of FIG. 7 and the exemplary hanger hook 100 of FIG. 1. Strap 1504 of headset 1500 is captured by hanger hook 100, whereas strap 1506 of headset 1502 hangs on exemplary prior art hook 700, waiting to be dislodged by a 3 G force from a bump in the road.
FIG. 16 includes front-side perspective views illustrating, for comparison, the prior art hook 700 of FIG. 7 and the exemplary hanger hook 100 of FIG. 1. Strap 1504 of headset 1500 is captured by hanger hook 100, whereas strap 1506 of headset 1502 hangs on exemplary prior art hook 700, waiting to be dislodged by a 3 G force from a bump in the road.
FIG. 17 includes right side elevation views illustrating, for comparison, the prior art hook 700 of FIG. 7 and the exemplary hanger hook 100 of FIG. 1. Strap 1504 of headset 1500 is captured by hanger hook 100, whereas strap 1506 of headset 1502 hangs on exemplary prior art hook 700, waiting to be dislodged by a 3 G force from a bump in the road. It can be appreciated from this view that the rotation of the hanger hook 100 about an axis normal to the drawing page would not dislodge the strap 1504. Accordingly, the hanger hook 100 is adaptable to be used on more surfaces within an emergency vehicle or in any other application.
FIG. 18 includes rear-side perspective views illustrating for comparison of the prior art hook 700 of FIG. 7 and the exemplary hanger hook 100 of FIG. 1. Strap 1504 of headset 1500 is captured by hanger hook 100, whereas strap 1506 of headset 1502 hangs on exemplary prior art hook 700, waiting to be dislodged by a 3 G force from a bump in the road.
FIG. 19 includes left side elevation views illustrating for comparison of the prior art hook 700 of FIG. 7 and the exemplary hanger hook 100 of FIG. 1. Strap 1504 of headset 1500 is captured by hanger hook 100, whereas strap 1506 of headset 1502 hangs on exemplary prior art hook 700, waiting to be dislodged by a 3 G force from a bump in the road. It can be appreciated from this view that the rotation of the hanger hook 100 about an axis normal to the drawing page would not dislodge the strap 1504. Accordingly, the hanger hook 100 is adaptable to be used on more surface orientations within an emergency vehicle or in any other application.
FIG. 20 includes top plan views illustrating for comparison of the prior art hook 700 of FIG. 7 and the exemplary hanger hook 100 of FIG. 1. This view shows most clearly that vertical motion of the headset 1500 would still result in retention of strap 1504 in hanger hook 100, while vertical motion of headset 1502 would result in strap 1506 not being retained in exemplary prior art hook 700.
FIG. 21 includes side-front perspective views illustrating for comparison of the prior art hook 700 of FIG. 7 and the exemplary hanger hook 100 of FIG. 1. This view illustrates that a single twisting motion will enable retrieval of headset 1500 from hanger hook 100.
FIG. 22 is a side elevation view illustrating an exemplary hanger hook 100 installed on a panel 2102, according to the preferred embodiment of FIG. 1. Panel 2102 may be any manufactured surface, such as a structural member in an emergency vehicle or a panel in an electronics chassis. Exemplary fastener 2108 is illustrated as a bolt 2104 with a rounded and slotted head and a nut 2106. Bolt 2104 is inserted through central opening 104 and through a prepared bolt hole in the panel 2102 before receiving nut 2106. The exemplary fastener 2108 is not intended to be limiting, but any portion of the fastener 2108 that protrudes into the hanger hook, such as the round head of bolt 2104, should not catch on straps placed within the hanger hook 100. For example, a wing bolt is not recommended.
While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing the exemplary embodiment or exemplary embodiments. It should be understood that various changes can be made in the function and arrangement of elements without departing from the scope of the invention as set forth in the appended claims and the legal equivalents thereof.
