Patent Description:
Internal structure of vehicles, aircraft and buildings use structural members such as beams formed with openings for components, such as electrical cables, electrical conduit, and the like, that extend through the openings in the structural members. These openings, which are formed in various ways, such as by stamping, cutting, punching and the like, often have sharp edges which can abrade or cut cable insulation or otherwise damage the components extending through the beam openings. Consequently, it is a common practice to protect the components by providing brackets or bushings which fit into the openings to cover their edges.

Various types of bushings are known and used for the purpose described. One known construction is composed of two parts which snap together when the bushing is installed in a beam opening. This type of bushing has several disadvantages and objections, including the need to make and store multiple parts, and the time and inconvenience of handling and assembling the bushing parts on site.

One-piece bushings are known, but present certain problems and disadvantages. For example, some of the conventional one-piece bushings are difficult to insert into the opening. This is particularly true when the bushings are configured to resist being dislodged as the electrical cables or other components are pulled through them.

Another objection common to both and multiple piece and one piece bushings of the prior art is that they are not designed so that a single bushing can accommodate a wide range of different thicknesses of the structural members. Since structural members are made with different thicknesses, it has been necessary to maintain a supply of different size bushings that can be selected and used depending upon the stud structure.

A prior art system for mounting pipes to a structural component is disclosed in patent <CIT>. The system includes a cuboidal clip portion with internal engagement claws which resiliently engage a stud-bolt to secure the system to the structural component. The clip portion is latchingly retained in a clamp body which has projecting therefrom a holding part which resiliently retains the pipes. A further system for supporting conduits or wires on a guide rail is disclosed in patent <CIT>. The system includes a U-shaped plate, a first leg of which is connected by means of a pin to the guide rail. The system also includes a closing member which engages the first leg and extends across an opening of the U-shaped plate to close the opening.

It would, therefore, be beneficial to provide a self-locking clamp, mounting system and method which overcomes the problems with the known art by providing a system which is easy to install, can be used with structural members of varying thickness and which can be properly mounted to the structural member in a fixed orientation. It would also be beneficial to provide a self-locking, tool free, hardware free attachment system which allows for a clamp to be mounted to a bracket of the mounting system.

The solution is provided by a mounting system which includes a bracket and a clamp according to claim <NUM>.

Other features and advantages of the present invention will be apparent from the following more detailed description of the illustrative embodiment, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.

The invention is directed to a mounting system for mounting to a structural component and for protecting a component such as a cable passing through an opening in the structural component, the mounting system includes a bracket and a clamp.

The method includes: installing a bracket on the structural component, the bracket having a grommet portion configured to be fastened to the structural component by means of fastening members and a mounting projection with a mounting opening extending from the grommet portion ; securing the bracket to the structural component to prevent rotation of the bracket relative to the structural member; positioning a clamp on the mounting projection of the bracket, the clamp having a clamping portion and a mounting portion, the mounting portion having a projection receiving opening which receives a projection extending from the bracket, the mounting portion having a securing opening which extends through side walls of the mounting portion into the projection receiving opening; and rotating a securing portion of the mounting portion of the clamp to a locked position, in which the securing portion is positioned in the mounting opening, to secure the clamp to the bracket.

As shown in <FIG>, an illustrative bracket <NUM> is shown in an opening <NUM> of a structural member <NUM>. The bracket <NUM> may be of, for example, polymer material, thermoplastic material, composite material or metal. The opening <NUM> may be a lightening hole or other type of opening. The structural member <NUM> may be, but is not limited to, a frame or bulkhead of a vehicle, a beam or a bulkhead of an aircraft, or a beam of a building. The opening <NUM> may be formed in various ways, such as by stamping, cutting, punching and the like. The opening <NUM> has a side wall or edge which can abrade or cut or otherwise damage components extending through the opening <NUM>. The components may be, but are not limited to cables, cable bundles or pipes. The bracket <NUM> shown is meant to be illustrative, as other embodiments of the bracket <NUM> may be used. For example, the bracket <NUM> may be, but is not limited to, an L-shaped bracket, an edge mounted bracket, a revolving adhesively mounted bracket, a revolving rive mounted bracket.

The bracket <NUM> includes a circular section or grommet portion <NUM> which is fastened to the structural member <NUM> by means of fastening members <NUM>, such as, but not limited to, rivets. The bracket <NUM> is fastened to the structural member <NUM> to prevent the rotation of the bracket <NUM> relative to the structural member <NUM>. A flange <NUM> and structural plate <NUM> extend from the grommet portion <NUM>. The flange <NUM> cooperates with the structural member <NUM> to properly position the grommet portion <NUM> relative to the structural member <NUM>. The structural plate <NUM> cooperates with the fastening members <NUM> to retain the grommet portion <NUM> to the structural member <NUM>. An axis of opening <NUM> is perpendicular to the plane of the structural plate.

As shown in <FIG>, the grommet portion <NUM> has a circular lateral cross section. However, the grommet portion <NUM> may have other configurations, such as, but not limited to, an oblong lateral cross section without departing from the scope of the invention. The grommet portion <NUM> is shaped and sized to suitably fit the opening <NUM>. The circular grommet portion <NUM> is formed to fit inside the opening <NUM> in the structural member <NUM>, and the grommet portion <NUM> is of sufficient length to ensure that the components do not come into contact with the side wall of the structural member <NUM>. The bracket <NUM> is configured to support components and protect them from the side wall or edges of the structural member <NUM> to which the bracket <NUM> is mechanically fixed.

As shown in <FIG>, a mounting projection or protrusion <NUM> extends from the grommet portion <NUM>. The projection <NUM> has a top or cable support wall <NUM>, and oppositely facing bottom wall <NUM> and side walls <NUM> which extend between the cable support wall <NUM> and the bottom wall <NUM>. The cable support wall <NUM> is positioned in line with an inner surface <NUM> of the grommet portion <NUM>. A securing or mounting opening <NUM> extends through the projection <NUM> in a direction which is essentially parallel to the cable support wall <NUM>. The opening <NUM> extends through the side walls <NUM>. As shown in <FIG>, <FIG> and <FIG>, the opening <NUM> has a first or front wall <NUM> and a second or back wall <NUM>.

Referring to <FIG>, a cable clamp <NUM> may be used to secure the component to the bracket <NUM> and to the structural member <NUM>. In the illustrative embodiment shown, the clamp <NUM> has a mounting portion <NUM> and a clamping portion <NUM>. The clamping portion <NUM> has a fixed clamping arm <NUM> and a movable clamping arm <NUM> which pivots about pivot member <NUM> between and open position and a closed or clamped position. The movable clamping arm <NUM> cooperates with the component when the component is positioned between the fixed clamping arm <NUM> and the movable clamping arm <NUM> and the movable clamping arm <NUM> is moved to the closed position. The fixed clamping arm <NUM> extends from and is attached to the mounting portion <NUM>. In the illustrative embodiment, the clamping portion <NUM> is a P-clamp, but other types of clamps can be used. P-clamps are described in <CIT> and <CIT>.

The clamping portion <NUM> may be configured to cooperate with different sized components. For example, when in the closed or clamped position the clamping portion may have a diametrical range of: <NUM>-<NUM>; <NUM>-<NUM>; <NUM>-<NUM>; <NUM>-<NUM>; <NUM>-<NUM>; <NUM>-<NUM>; or <NUM>-<NUM>.

As shown in <FIG>, <FIG> and <FIG>, the mounting portion <NUM> has a front wall <NUM>, a back wall <NUM>, and side walls <NUM>. A projection receiving opening <NUM> extends through the mounting portion <NUM> from one side wall <NUM> to an opposite side wall <NUM>.

The opening <NUM> has a front or first wall <NUM>. The opening is dimensioned to receive the projection <NUM> therein. The opening <NUM> is configured to have a similar, but slightly larger configuration than the projection <NUM> to allow the projection <NUM> to be inserted into the opening <NUM>, while preventing the unwanted movement of the clamp <NUM> relative to the bracket <NUM>.

A latch receiving cavity <NUM> is provided in the front wall <NUM> of the mounting portion <NUM>. The latch receiving cavity <NUM> extends from one side wall <NUM> to the opposite side wall <NUM>. Securing member receiving openings or cavities <NUM> extend through side walls <NUM> into the opening <NUM>.

As shown in <FIG>, <FIG> and <FIG>, a latching mechanism <NUM> is positioned in the latch receiving cavity <NUM>. The latching mechanism <NUM> has a first latching arm <NUM> which extends from a cross member <NUM> which is retained in the latch receiving cavity <NUM>. The first latching arm <NUM> has a first engagement portion <NUM>, a first pivoting portion <NUM> and a first securing member or portion <NUM>. The first pivoting portion <NUM> has a first opening <NUM> provided therein. The first securing portion <NUM> has a first securing surface <NUM> provided at a free end of the first securing portion <NUM> which is spaced from the first pivoting portion <NUM>. The first securing portion <NUM> has a first camming surface <NUM> which extends between the first securing surface <NUM> and the first pivoting portion <NUM>.

The latching mechanism <NUM> has a second latching arm <NUM> which extends from the cross member <NUM> which is retained in the latch receiving cavity <NUM>. The second latching arm <NUM> has a second engagement portion <NUM>, a second pivoting portion <NUM> and a second securing portion <NUM>. The second pivoting portion <NUM> has a second opening <NUM> provided therein. The second securing portion <NUM> has a second securing surface <NUM> provided at a free end of the second securing portion <NUM> which is spaced from the second pivoting portion <NUM>. The second securing portion <NUM> has a second camming surface <NUM> which extends between the second securing surface <NUM> and the second pivoting portion <NUM>. The second latching arm <NUM> has an overstress protection member <NUM> (<FIG>) which extends from the second engagement portion <NUM>.

The first opening <NUM> and the second opening <NUM> are inserted over posts <NUM> of the mounting portion <NUM> to retain the latching mechanism <NUM> in position on the mounting portion <NUM>. In addition, the cross member <NUM> which is positioned in the latch receiving cavity <NUM> to further retain the latching mechanism <NUM> in position on the mounting portion <NUM>. The positioning of the posts <NUM> in the openings <NUM>, <NUM> allows the securing portion <NUM>, <NUM> to pivot or rotate about the posts <NUM>. The positioning of the cross member <NUM> in the latch receiving cavity <NUM> prevent the latching mechanism from moving in a direction in line with a longitudinal axis <NUM> (<FIG>) of the mounting portion <NUM>. However, the cross member <NUM> is free to move in the latch receiving cavity <NUM> in a direction which is transverse to the longitudinal axis <NUM> of the mounting portion <NUM>.

The first securing portion <NUM> is configured to rotate about a respective post <NUM> between a first or unlocked position (as shown in <FIG>) and a second or locked position (as shown in <FIG>). The second securing portion <NUM> is configured to rotate about another respective post <NUM> between a first or unlocked position (as shown in <FIG>) and a second or locked position (as shown in <FIG>).

The installation of the clamp <NUM> onto the mounting projection <NUM> of the bracket <NUM> is shown in <FIG>. Prior to the clamp <NUM> engaging the mounting projection <NUM>, the latching mechanism <NUM> is in the position shown in <FIG> and <FIG>. In this position, the first camming surface <NUM> and a portion of the first securing surface <NUM> of the first securing portion <NUM> extend through a securing member receiving cavity <NUM> and into the projection receiving opening <NUM>. The configuration of the latching mechanism <NUM> and the cooperation of the first pivoting portion <NUM> with the post <NUM> resiliently maintains the first camming surface <NUM> and the portion of the first securing surface <NUM> of the first securing portion <NUM> in the initial position.

Similarly, the second camming surface <NUM> and a portion of the second securing surface <NUM> of the second securing portion <NUM> extend through the securing member receiving cavity <NUM> and into the projection receiving opening <NUM>. The configuration of the latching mechanism <NUM> and the cooperation of the second pivoting portion <NUM> with the post <NUM> resiliently maintains the second camming surface <NUM> and the portion of the second securing surface <NUM> of the second securing portion <NUM> in the initial position.

As the clamp <NUM> is moved onto the mounting projection <NUM> of the bracket <NUM>, as shown in <FIG> and <FIG>, the mounting projection <NUM> is moved into the projection receiving opening <NUM>. As this occurs, the side walls <NUM> of the mounting projection <NUM> engage the first camming surface <NUM> and the second camming surface <NUM>, causing the camming surfaces <NUM>, <NUM> and the securing portions <NUM>, <NUM> to resiliently pivot about the pivoting portions <NUM>, <NUM> and the posts <NUM>. This allows for the continued insertion of the clamp <NUM> onto the mounting projection <NUM> of the bracket <NUM>.

Insertion continues until the mounting projection <NUM> engages or is proximate to the wall <NUM> of the projection receiving opening <NUM>, as shown in <FIG> and <FIG>. In this position, the camming surfaces <NUM>, <NUM> are positioned in line with the securing or mounting opening <NUM> of the mounting projection <NUM>. This allows the camming surfaces <NUM>, <NUM> and the securing portions <NUM>, <NUM> to pivot about the pivoting portions <NUM>, <NUM> and the posts <NUM> to resiliently return toward their unstressed or initial position. As shown in <FIG>, with the securing portions <NUM>, <NUM> positioned in the mounting opening <NUM>, the securing surfaces <NUM>, <NUM> engage or are proximate to the first or front wall <NUM> of the opening <NUM>. In this position, the clamp <NUM> is secured to the mounting projection <NUM> of the bracket <NUM>.

As shown in <FIG>, the latching mechanism <NUM> resists the unwanted removal of the clamp <NUM> from the mounting projection <NUM> of the bracket <NUM>. If a force F1 is applied to the clamp <NUM>, resulting forces F2 and F3 will be applied to the securing surfaces <NUM>, <NUM> of the securing portions <NUM>, <NUM> of the latching mechanism <NUM>. As the securing surfaces <NUM>, <NUM> have an arcuate configuration, the application of forces causes the securing surfaces <NUM>, <NUM> and the securing portions <NUM>, <NUM> to pivot further into the mounting opening <NUM>, thereby preventing the unwanted removal of the clamp <NUM> from the bracket <NUM>.

In order to remove the clamp <NUM> from the mounting projection <NUM> of the bracket <NUM>, an operator or user applies forces F4 and F5 to the first engagement portion <NUM> of the of the first latching arm <NUM> and to the second engagement portion <NUM> of the second latching arm <NUM>. The application of the forces F4 and F5 causes the latching arms <NUM>, <NUM> to move inward, toward each other. This in turn causes the securing surfaces <NUM>, <NUM> and the securing portions <NUM>, <NUM> to pivot outward about the pivoting portions <NUM>, <NUM> and the posts <NUM>, causing the securing surfaces <NUM>, <NUM> to be moved out of the opening <NUM>. With the securing surfaces <NUM>, <NUM> removed from the opening <NUM>, the clamp <NUM> may be removed from the mounting projection <NUM> of the bracket <NUM>.

The first latching arm <NUM> and the second latching arm <NUM> comprise two pivoting self-locking latches which ensure that the cable clamp <NUM> cannot vibrate loose from the bracket <NUM> when the latching arms <NUM>, <NUM> are in a locked condition. Having two self-locking latching arms <NUM>, <NUM> adds an element of redundancy as either of the two pivoting self-locking latching arms <NUM>, <NUM> can securely retain the clamp <NUM> to the bracket <NUM> alone. Additionally, when the latching arms <NUM>, <NUM> are in a locked position they self-tighten, or self-lock due to the geometry of its design.

The latching arms <NUM>, <NUM> and the latching mechanism <NUM> allow the user to install the clamp <NUM> by simply pushing it onto the mounting projection <NUM> of the bracket <NUM>. The latching arms <NUM>, <NUM> of the latching mechanism <NUM> automatically lock into place, thus simplifying the installation procedure and removing the risk of forgetting to latch the clamp in place.

The latching mechanism <NUM> and latching arms <NUM>, <NUM> are ergonomically & spatially designed. The user simply has to squeeze the first engagement portion <NUM> and the second engagement portion <NUM> of the latching mechanism <NUM> and pulls the clamp <NUM> free from the bracket <NUM>. The squeezing of the first engagement portion <NUM> and the second engagement portion <NUM> causes the two pivoting latching arms <NUM>, <NUM> to be moved out of the locked position and allows the clamp <NUM> to be removed.

An alternative embodiment of a clamp <NUM> is shown in <FIG>. As shown in <FIG>, the latching mechanism <NUM> has a latching arm <NUM> with an engagement portion <NUM>, a pivoting portion <NUM> and a securing member or portion <NUM>. The pivoting portion <NUM> has an opening provided therein. The securing portion <NUM> has a securing surface <NUM> provided at a free end of the securing portion <NUM> which is spaced from the pivoting portion <NUM>.

The first opening <NUM> is inserted over post <NUM> of the mounting portion <NUM> to retain the latching mechanism <NUM> in position on the mounting portion <NUM>. The positioning of the post <NUM> in the opening <NUM> allows the securing portion <NUM> to pivot or rotate about the post <NUM>. The securing portion <NUM> is configured to rotate about the post <NUM> between a first or unlocked position (as shown in <FIG>) and a second or locked position (as shown in <FIG>).

The installation of the clamp <NUM> onto the mounting projection <NUM> of the bracket <NUM> is shown in <FIG>. Prior to the clamp <NUM> engaging the mounting projection <NUM>, the latching mechanism <NUM> is in the position shown in <FIG>. In this position, the first securing surface <NUM> of the securing portion <NUM> does not extend through a securing member receiving cavity <NUM> and does not extend into the projection receiving opening <NUM>. The camming surface <NUM> and the portion of the securing surface <NUM> of the securing portion <NUM> are in the initial position.

Insertion of the clamp <NUM> onto the bracket <NUM> continues until the clamp <NUM> engages or is proximate to the bracket, as shown in <FIG>. In this position, the latching mechanism <NUM> is rotated from the position shown in <FIG> to the position shown in <FIG>. As this occurs, the camming surfaces <NUM>, which are positioned in line with the securing or mounting opening <NUM> of the mounting projection <NUM>, pivot about the pivoting portions <NUM> and the post <NUM> to move to the locked position, in which the securing portion <NUM> is positioned in the mounting opening <NUM>. In this position, the securing surface 177engages or are proximate to the first or front wall <NUM> of the opening <NUM>, thereby securing the clamp <NUM> the mounting projection <NUM> of the bracket <NUM>.

As shown in <FIG>, the latching mechanism <NUM> resists the unwanted removal of the clamp <NUM> from the mounting projection <NUM> of the bracket <NUM>. If a force F6 is applied to the clamp <NUM>, resulting forces F7 will be applied to the securing surface <NUM> of the securing portion <NUM> of the latching mechanism <NUM>. As the securing surface <NUM> has an arcuate configuration, the application of forces causes the securing surface 177and the securing portion <NUM> to pivot or rotate further into the mounting opening <NUM>, thereby preventing the unwanted removal of the clamp <NUM> from the bracket <NUM>.

In order to remove the clamp <NUM> from the mounting projection <NUM> of the bracket <NUM>, an operator or user rotates the latching mechanism <NUM> from the position shown in <FIG> to the position shown in <FIG>. This causes the securing surface <NUM> to be moved out of the opening <NUM>. With the securing surface <NUM> removed from the opening <NUM>, the clamp <NUM> may be removed from the mounting projection <NUM> of the bracket <NUM>.

The clamps <NUM>, <NUM> provide a reliable means of securely fastening the component, such as cable bundle, in a tool-less and fast to install manner, reducing the number of parts needed to be stocked. Additionally, the first latching mechanisms <NUM>, <NUM> ensure that the clamps <NUM>, <NUM> are secure to the component and the bracket <NUM> and cannot vibrate loose.

Referring to <FIG>, an alternate bracket <NUM> is shown in an opening <NUM> of a structural member <NUM>. The bracket <NUM> may be of, for example, polymer material, thermoplastic material, composite material or metal. The opening <NUM> may be a lightening hole or other type of opening. The structural member <NUM> may be, but is not limited to, a frame or bulkhead of a vehicle, a beam or a bulkhead of an aircraft, or a beam of a building. The opening <NUM> may be formed in various ways, such as by stamping, cutting, punching and the like. The opening <NUM> has a side wall or edge which can abrade or cut or otherwise damage components <NUM> extending through the opening <NUM>. The components <NUM> may be, but are not limited to cables, cable bundles or pipes.

As shown in <FIG>, the grommet portion <NUM> has a circular lateral cross section. However, the grommet portion <NUM> may have other configurations, such as, but not limited to, an oblong lateral cross section. The grommet portion <NUM> is shaped and sized to suitably fit the opening <NUM>. The circular grommet portion <NUM> is formed to fit inside the opening <NUM> in the structural member <NUM>, and the grommet portion <NUM> is of sufficient length to ensure that the components <NUM> do not come into contact with the side wall of the structural member <NUM>. The bracket <NUM> is configured to support components <NUM> and protect them from the side wall or edges of the structural member <NUM> to which the bracket <NUM> is mechanically fixed.

As shown in <FIG>, a projection or protrusion <NUM> extends from the grommet portion <NUM>. The projection <NUM> has a top or cable support wall <NUM>, and oppositely facing bottom wall <NUM> and side walls <NUM> which extend between the cable support wall <NUM> and the bottom wall <NUM>. The cable support wall <NUM> is positioned in line with an inner surface <NUM> of the grommet portion <NUM>. A mounting opening <NUM> extends through the projection <NUM> in a direction which is essentially parallel to the cable support wall <NUM>. The opening <NUM> extends through the side walls <NUM>.

As shown in <FIG> and <FIG>, securing projection <NUM> extends from the bottom wall <NUM> in a direction away from the cable support wall <NUM>. The securing projection <NUM> has a securing shoulder or wall <NUM> which faces and is essentially parallel to a surface of the structural member <NUM>, although other configurations and orientations of the securing projection <NUM> and the securing shoulder <NUM> may be used.

As shown in <FIG> and <FIG>, the cable bundle or component <NUM> is inserted through the grommet portion <NUM> of the bracket <NUM> which is positioned in the opening <NUM> of the structural member <NUM>. The component <NUM> is positioned in contact with the inner surface <NUM> of the grommet portion <NUM> and the cable support wall <NUM> of the projection <NUM>. As shown in <FIG>, a portion of a tie or strap <NUM> is positioned in the mounting opening <NUM> to properly position and secure the mounting opening <NUM> relative to the projection <NUM>. The tie or strap <NUM> is then wrapped around the component <NUM> and tightened to secure the component <NUM> to the projection <NUM> and to the bracket <NUM>. The tie or strap <NUM> operates in a known manner, such as, but not limited to a push mount type tie that includes a self-locking pin. In other embodiments, the tie or strap <NUM> is positioned in the mounting opening <NUM> prior to the component <NUM> being positioned in contact with the inner surface <NUM> of the grommet portion <NUM> and the cable support wall <NUM> of the projection <NUM>.

Referring to <FIG>, an alternate cable clamp <NUM> not according to the claimed invention may be used to secure the component to the bracket <NUM> and to the structural member <NUM>. In the illustrative embodiment shown, the clamp <NUM> has a mounting portion <NUM> and a clamping portion <NUM>. The clamping portion <NUM> has a fixed clamping arm <NUM> and a movable clamping arm <NUM> which pivots about pivot member <NUM> between and open position and a closed or clamped position. The movable clamping arm <NUM> cooperates with the component when the component is positioned between the fixed clamping arm <NUM> and the movable clamping arm <NUM> and the movable clamping arm <NUM> is moved to the closed position. The fixed clamping arm <NUM> extends from and is attached to the mounting portion <NUM>. In the illustrative embodiment, the clamping portion <NUM> is a P-clamp, but other types of clamps can be used. P-clamps are described in <CIT> and <CIT>.

The mounting portion <NUM> has a top wall <NUM>, a bottom wall <NUM> and side walls <NUM> which extend between the top wall <NUM> and the bottom wall <NUM>. A projection receiving opening <NUM> extends through the mounting portion <NUM> from one side wall <NUM> to an opposite side wall <NUM>. The opening <NUM> is dimensioned to receive the projection <NUM> therein. The opening <NUM> is configured to have a similar, but slightly larger configuration than the projection <NUM> to allow the projection <NUM> to be inserted into the opening <NUM>, while preventing the unwanted movement of the clamp <NUM> relative to the bracket <NUM>.

As shown in <FIG> and <FIG>, a latch receiving cavity <NUM> is provided in the bottom wall <NUM> of the mounting portion <NUM>. The latch receiving cavity <NUM> extends from one side wall <NUM> toward or to the opposite side wall <NUM>. An enlarged recess <NUM> intersects the latch receiving cavity <NUM> proximate the one side wall <NUM>. The latch receiving cavity <NUM> has an opening <NUM> which extend between the latch receiving cavity <NUM> and the projection receiving opening <NUM>. The opening <NUM> is positioned proximate the opposite side wall <NUM>. The enlarged recess <NUM> has projections <NUM> which extend into the recess <NUM>.

As shown in <FIG> and <FIG>, a latching mechanism <NUM> is positioned in the latch receiving cavity <NUM>. The latching mechanism <NUM> has a securing portion engagement end <NUM> with a latching shoulder or wall <NUM> and an operator engagement end <NUM>. The latching shoulder <NUM> of the securing portion engagement end <NUM> engages the securing shoulder <NUM> of the securing projection <NUM> of the projection <NUM> to securely position and maintain the mounting portion <NUM> and the clamp <NUM> to the projection <NUM> of the bracket <NUM>. The latching mechanism <NUM> is configured to rotate in the latch receiving cavity <NUM> between a first or unlocked position (as shown in <FIG> and <FIG>) and a second or locked position (as shown in <FIG> and <FIG>), as will be more fully described.

In operation, the clamp <NUM> is provided proximate the component <NUM> after the component <NUM> has been inserted through the bracket <NUM>, as shown in <FIG>. The clamp <NUM>, with the clamping portion <NUM> in the open position, is then moved onto the component <NUM>, as shown in <FIG>. In this position the latching mechanism <NUM> are in first or unlocked positions.

The clamp <NUM> is moved toward the structural member <NUM>. As this occurs, the projection <NUM> of the bracket <NUM> enters the projection receiving opening <NUM> of the mounting portion <NUM> of the clamp <NUM>, allowing the clamp to move the position shown in <FIG> and <FIG>.

With the clamp <NUM> properly positioned on the projection <NUM>, the latching mechanism <NUM> is rotated in the latch receiving cavity <NUM> from the unlocked position, shown in <FIG> and <FIG>, to the locked position, shown in <FIG> and <FIG>. As the latching mechanism <NUM> is rotated, the latching shoulder <NUM> of the securing portion engagement end <NUM> of the latching mechanism <NUM> is moved in the opening <NUM> from the unlocked position, shown in <FIG>, to the locked position, shown in <FIG>. In the locked position, the latching shoulder <NUM> of the securing portion engagement end <NUM> engages the securing shoulder <NUM> of the securing projection <NUM> of the protrusion <NUM>. As the securing shoulder <NUM> and the latching shoulder <NUM> are in engagement, the removal of the clamp <NUM> from the projection <NUM> of the bracket <NUM> is prevented.

As the rotation occurs, the operator engagement end <NUM> of the latching mechanism <NUM> is also moved from the unlocked position, shown in <FIG>, to the locked position, shown in <FIG>. In the locked position the operator engagement end <NUM> is positioned within the enlarged recess <NUM>, the operator engagement end <NUM> engages and is placed in frictional engagement with the projections <NUM> which extend into the recess <NUM>, thereby providing an interference fit between the operator engagement end <NUM> and the projections <NUM>. The interference fit prevents the unwanted movement of the operator engagement end <NUM> and the latching mechanism <NUM> from the locked position to the unlocked position, such as, but not limited to, in environments in which the clamp <NUM> and bracket <NUM> are exposed to vibration. In addition, the positioning of the operator engagement end <NUM> in the enlarged recess <NUM> protects the operator engagement end <NUM> from unwanted and inadvertent engagement. The positioning of the operator engagement end <NUM> in the enlarged recess <NUM> also provides a visual and physical check to make certain that the clamp <NUM> is properly positioned and secured to the bracket <NUM>.

With the clamp <NUM> properly locked to the bracket <NUM>, the movable clamping arm <NUM> is rotated to the closed position, as shown in <FIG> and <FIG>. In this position, the clamping portion <NUM> is secured in the closed position, thereby securing the component <NUM> in the clamp <NUM>.

An alternative embodiment of a clamp <NUM> not according to the claimed invention is shown in <FIG> and <FIG>. In this embodiment the clamp <NUM> is larger to accommodate a larger cable or component <NUM>. However, the operation of the clamp <NUM> is the same as described with respect to clamp <NUM>.

The clamp <NUM>, <NUM> provides a reliable means of securely fastening the component <NUM>, <NUM>, such as cable bundle, in a tool-less and fast to install manner, reducing the number of parts needed to be stocked. Additionally, the latching mechanism <NUM> ensures that the clamp <NUM>, <NUM> is secure to the component <NUM>, <NUM> and the bracket <NUM> and cannot vibrate loose.

Referring to <FIG>, an alternate bracket <NUM> is shown in an opening <NUM> of a structural member <NUM>. The bracket <NUM> may be of, for example, polymer material, thermoplastic material, composite material or metal. The opening <NUM> may be a lightening hole or other type of opening. The structural member <NUM> may be, but is not limited to, a frame or bulkhead of a vehicle, a beam or a bulkhead of an aircraft, or a beam of a building. The opening <NUM> may be formed in various ways, such as by stamping, cutting, punching and the like. The opening <NUM> has a side wall or edge which can abrade or cut or otherwise damage components <NUM> extending through the opening <NUM>. The components <NUM> may be, but are not limited to cables or cable bundles.

The bracket <NUM> includes a circular section or grommet portion <NUM> which is fastened to the structural member <NUM> by means of fastening members <NUM>, such as, but not limited to, rivets. The bracket <NUM> is fastened to the structural member <NUM> to prevent the rotation of the bracket <NUM> relative to the structural member <NUM>. A flange and structural plate (not shown) are disposed at a first end <NUM> of the grommet portion <NUM>. The flange cooperates with the structural member <NUM> to properly position the grommet portion <NUM> relative to the structural member <NUM>. The structural plate cooperates with the fastening members <NUM> to retain the grommet portion <NUM> to the structural member <NUM>. An axis of opening <NUM> is perpendicular to the plane of the structural plate. A second end <NUM> of the grommet portion <NUM> does not include a flange.

The grommet portion <NUM> has a circular lateral cross section. However, the grommet portion <NUM> may have other configurations, such as, but not limited to, an oblong lateral cross section without departing from the scope of the invention. An outer surface <NUM> of the grommet portion <NUM> is shaped and sized to suitably fit the opening <NUM>, such that the outer surface <NUM> is proximate to or in engagement with the side wall of the opening <NUM>. The circular grommet portion <NUM> is formed to fit inside the opening <NUM> in the structural member <NUM>, and the grommet portion <NUM> is of sufficient length to ensure that the components <NUM> do not come into contact with the side wall of the structural member <NUM>. The bracket <NUM> is configured to support components <NUM> and protect them from the side wall or edges of the structural member <NUM> to which the bracket <NUM> is mechanically fixed.

A projection or protrusion <NUM> extends from the second end <NUM> of the grommet portion <NUM> in a direction away from the first end <NUM>. The projection <NUM> has a top or cable support wall <NUM>, and oppositely facing bottom wall <NUM> and side walls <NUM> which extend between the cable support wall <NUM> and the bottom wall <NUM>. The cable support wall <NUM> is positioned in line with an inner surface <NUM> of the grommet portion <NUM>. A mounting opening <NUM> extends through the projection <NUM> in a direction which is essentially parallel to the cable support wall <NUM>. The opening <NUM> extends through the side walls <NUM>.

Referring to <FIG>, an alternate cable clamp or clamp <NUM> not according to the claimed invention may be used to secure the component <NUM> to the bracket <NUM> and to the structural member <NUM>. In the illustrative embodiment shown, the clamp <NUM> has a mounting portion <NUM> and a clamping portion <NUM>. The clamping portion <NUM> has a fixed clamping arm <NUM> and a movable clamping arm <NUM> which pivots about pivot member <NUM> between and open position and a closed or clamped position. The movable clamping arm <NUM> has a compressible or resilient member <NUM> which is provided on an inside portion of the movable clamping arm <NUM>. The compressible or resilient member <NUM> cooperates with the component <NUM> when the component <NUM> is positioned between the fixed clamping arm <NUM> and the movable clamping arm <NUM> and the movable clamping arm <NUM> is moved to the closed position. The fixed clamping arm <NUM> extends from and is attached to the mounting portion <NUM>. In the illustrative embodiment, the clamping portion <NUM> is a P-clamp, but other types of clamps can be used. The clamping portion <NUM> may be configured to cooperate with different sized components. For example, when in the closed or clamped position the clamping portion may have a diametrical range of: <NUM>-<NUM>; <NUM>-<NUM>; <NUM>-<NUM>; <NUM>-<NUM>; <NUM>-<NUM>; <NUM>-<NUM>; or <NUM>-<NUM>.

A latching mechanism <NUM> extends from the movable clamping arm <NUM> proximate a free end of the movable clamping arm <NUM>. The latching mechanism <NUM> has a mounting portion engagement end <NUM> and an operator engagement end <NUM>. The mounting portion engagement end <NUM> engages a movable clamping arm engagement portion <NUM> of the mounting portion <NUM> to securely position and maintain the movable clamping arm <NUM> in the closed position.

The mounting portion <NUM> has a base <NUM> with a top wall <NUM>, a bottom wall <NUM> and side walls <NUM> which extend between the top wall <NUM> and the bottom wall <NUM>. A projection receiving opening <NUM> extends through the base <NUM> from one side wall <NUM> to an opposite side wall <NUM>. The opening <NUM> is dimensioned to receive the projection <NUM> therein. The opening <NUM> is configured to have a similar, but slightly larger configuration than the projection <NUM> to allow the projection <NUM> to be inserted into the opening <NUM>, while preventing the unwanted movement of the clamp <NUM> relative to the bracket <NUM>.

Recesses <NUM> are provided on the side walls <NUM>. The longitudinal axis of the recesses <NUM> extend in a direction which is essentially parallel to the plane of the top wall <NUM>. The recesses <NUM> extend from proximate the opening <NUM> to proximate an end wall <NUM> (<FIG>, <FIG>) of the mounting portion <NUM>.

Referring to <FIG>, <FIG>, a first recess or cavity <NUM> is provided in the bottom wall <NUM>. The first cavity <NUM> is provided proximate the end wall <NUM>. A second recess or cavity <NUM> is provided in the bottom wall <NUM>. The second cavity <NUM> is spaced from the first cavity <NUM> and is provided proximate the opening <NUM>.

The mounting portion <NUM> has a slidable locking member <NUM>. The slidable locking member <NUM> has a top wall <NUM>, a bottom wall <NUM> and side walls <NUM> which extend between the top wall <NUM> and the bottom wall <NUM>.

Projections <NUM> extend from each side wall <NUM> inwardly toward the opposite side wall <NUM>. The projections <NUM> are dimensioned to be received in the recesses <NUM> of the base <NUM>. The projections <NUM> may be dimples or have other configurations.

A latching arm <NUM> is provided on the bottom wall <NUM>. The latching arm <NUM> has a base <NUM>, which is attached to the bottom wall <NUM>, and a free end <NUM>. The free end <NUM> has a latching projection <NUM>. The latching arm <NUM> is configured to allow the free end <NUM> to be resiliently displaced relative to the base <NUM>.

As shown in <FIG>, a securing arm <NUM> extends from an end wall <NUM> of the slidable locking member <NUM>. The securing arm <NUM> is provided between the side walls <NUM>. The securing arm <NUM> has a free end <NUM> which is configured to be received in the mounting opening <NUM> of the projection <NUM>. The securing arm <NUM> has a tapered configuration <NUM> proximate the end wall <NUM> to provide structural integrity to the securing arm <NUM>.

In operation, the clamp <NUM> is provided proximate the component <NUM> after the component <NUM> has been inserted through the bracket <NUM>, as shown in <FIG>. The clamp <NUM>, with the clamping portion <NUM> in the open position, is then moved onto the component <NUM>, as shown in <FIG>. In this position, the slidable locking member <NUM> is positioned in an unlocked position. The slidable locking member <NUM> is retained in the unlocked position by the engagement of the latching projection <NUM> of the latching arm <NUM> with the first cavity <NUM> of the bottom wall <NUM> of the base <NUM>, as shown in <FIG> and <FIG>.

The clamp <NUM> is moved toward the structural member <NUM>. As this occurs, the projection <NUM> enters the projection receiving opening <NUM> of the base <NUM> of the mounting portion <NUM> of the clamp <NUM>, allowing the clamp to move the position shown in <FIG>.

With the clamp <NUM> properly positioned on the projection <NUM>, the slidable locking member <NUM> is moved from the unlocked position shown in <FIG> and <FIG> to the locked position shown in <FIG>, <FIG>. As the slidable locking member <NUM> is moved, the latching projection <NUM> of the latching arm <NUM> moves out of the first cavity <NUM> of the bottom wall <NUM> and slides across the bottom wall <NUM>, as shown in <FIG>. As this occurs, the projections <NUM> of the side walls <NUM> slide in the recesses <NUM> of the base <NUM>. In addition, the securing arm <NUM> is moved into the mounting opening <NUM> of the projection <NUM>.

This continues until the latching projection <NUM> of the latching arm <NUM> are moved into the second cavity <NUM>, placing the slidable locking member <NUM> in the locked position, as shown in <FIG>, <FIG>, <FIG>. In the locked position, as shown in <FIG>, the securing arm <NUM> is fully inserted into the mounting opening <NUM> of the projection <NUM>, thereby securing the clamp <NUM> to the bracket <NUM>. The slidable locking member <NUM> acts as a secondary lock to provide a visual and physical check to make certain that the clamp <NUM> is properly positioned and secured to the bracket <NUM>.

With the clamp <NUM> properly locked to the bracket <NUM>, the movable clamping arm <NUM> is rotated to the closed position, as shown in <FIG>. The operator engagement end <NUM> of the latching mechanism <NUM> is engaged and the latching mechanism <NUM> is rotated to the position shown in <FIG>. In this position, the clamping portion <NUM> is secured in the closed position, thereby securing the component <NUM> in the claim <NUM>.

The clamp <NUM> provides a reliable means of securely fastening the components, such as cable bundles, in a tool-less and fast to install manner, reducing the number of parts needed to be stocked. Additionally, the slidable locking member <NUM> ensures that the clamp <NUM> is secure to the bracket <NUM> and cannot vibrate loose.

The clamp <NUM> can be installed in the orientation shown or can be rotated <NUM> degrees. Once positioned on the bracket <NUM>, the clamp <NUM> and bracket <NUM> are fixed rotationally relative to the structural member <NUM>.

Referring to <FIG>, an alternate illustrative bracket outside the subject-matter of the claims <NUM> is shown. The bracket <NUM> may be of, for example, polymer material, thermoplastic material, composite material or metal. The bracket <NUM> includes a base portion <NUM>. The base portion <NUM> has a circular lateral cross section. However, the base portion <NUM> may have other configurations, such as, but not limited to, an oblong lateral cross section without departing from the scope of the invention.

A projection or protrusion <NUM> extends base portion <NUM>. The projection <NUM> has a top wall <NUM>, and oppositely facing bottom wall <NUM> and side walls <NUM> which extend between the top wall <NUM> and the bottom wall <NUM>. A mounting opening <NUM> extends through the projection <NUM> in a direction which is essentially parallel to the top wall <NUM>. The opening <NUM> extends through the side walls <NUM>. Clamps <NUM> of varying sizes may be mounted to the projections <NUM> of the bracket <NUM>. As the illustrative clamp <NUM> shown in <FIG> is inserted onto the projections <NUM> and operate in a similar manner to the clamp <NUM> previously described, the detailed description will not be repeated.
