The present invention relates to a mirror mount, and more particularly to a mirror mount that mounts a mirror to a fender of a vehicle.
There are a variety of vehicles, such as buses, shuttles and trucks, that have one or more fender mounted mirrors. These mirrors provide a rearward viewing perspective to an operator of the vehicle.
Most mirrors are mounted with mirror mounts including multiple support arms that are secured directly to a fender exterior of vehicle. Some mirror mounts, however, include a bracket that follows the contour of an outer surface of the fender. That bracket is strapped or screwed at a lower end directly to the outer fender exterior or “skin”. The bracket of these mounts includes a Z-shaped secondary bracket that extends from an upper end of the main bracket, across the top of the fender, and through a gap between the fender and hood of the vehicle. The Z-shaped secondary bracket is screwed to the bulkhead of the vehicle immediately under the edge of the hood.
While such constructions can reduce some vibration in the mirror transmitted through the typical thin outer fender skin, the fact that the bracket rests on and is supported by the fender skin can decrease the effectiveness of the vibration attenuation. This is because the bracket is still partially supported by the fender skin. Thus, an operator's view through the mirror still may appear blurry because the mirror vibrates. Parts of the mirror and the fender also can crack due to the vibration. Finally, these types of mirror mounts can be rather large, and can occupy valuable viewing space.
A mirror mount is provided to join a mirror with a fender of a vehicle. In one embodiment, the mount can include a base that faces a vehicle exterior fender without extending upwardly and under a hood of the vehicle. A support arm can extend from the base and can include a distal end that joins with a mirror. One or more pillars can extend away from the base.
In another embodiment, the pillars can be sized and shaped to extend through holes defined in the exterior fender to a frame member of the vehicle disposed inwardly relative to the fender. The pillars can be associated with respective fasteners to join with the frame member. Optionally, the pillars can be rigidly and non-rotatably joined with the base. The pillars can also remain unjoined with the exterior fender, and generally can be unsupported by the same.
In even another embodiment, the pillars can include a first end joined with the base and a second end separated from the first end by a distance. That distance can be substantially equal to the distance defined between the fender and the frame member. With this construction, the pillars and base can be secured to the frame member with the base optionally slightly clampingly engaging the exterior fender; but not being supported thereby. The pillars, rather than the exterior fender can support the base, the support arm and mirror.
In still another embodiment, the pillars can include a shoulder configured to engage and contact the frame member. A fastener can project from the second end adjacent the shoulder. Optionally, the fastener extends through the frame member, and can be joined with a nut that further fastens the fastener and the pillars to the frame member.
In yet another embodiment, the mirror mount pillars can define a bore. One or more independent and separate fasteners can be installed in the bore. Those fasteners can extend beyond the second end. A portion of the fasteners extending beyond the end can extend through the frame member to secure the pillars and base to the frame member.
In a further embodiment, the mirror mount can include a support block. The pillars can form a part of the support block. The support block can be sized and shaped for positioning between an inner surface of the exterior fender and the frame member. Optionally, the block and/or pillars can define one or more bores, and fasteners can extend through those bores and through the frame member.
The present invention provides a mirror mount that can transmit weight of a mirror, base, support arm and/or pillars directly to a frame member, optionally rather than the fender. This can reduce transmission of vibration inherent in the fender to the mirror, and can add structural rigidity to the mounted mirror because it mounts directly to and is supported primarily by a rigid structural part, that is, the frame member, rather than a flimsy exterior fender.
These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiments and the drawings.

The use of “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof. Further, enumeration may be used in the description of various embodiments. Unless otherwise expressly stated, the use of enumeration should not be construed as limiting the invention to any specific order or number of components. Nor should the use of enumeration be construed as excluding from the scope of the invention any additional steps or components that might be combined with or into the enumerated steps or components.
A mirror mount of a current embodiment is illustrated in
As shown in
As shown in
The fender 14 can be configured to transition to the hood 16 of the vehicle 100. The hood 16 includes a hood edge 17 that is positioned adjacent the uppermost portion 15 of the fender 14 and extends adjacent a concealed vertical portion 14V of the fender. The fender 14 also includes a fender side 14S which is located below the uppermost portion 15.
The vehicle can be structured so that the frame 2 includes frame outer wall 3. Of course in certain constructions, depending on the vehicle, additional walls can be included in the fence. Generally, the frame member or inner fender provides the structural support to the fender 14, which also can be referred to as an outer fender or fender skin. The frame member 2 can also support other items on the interior of the engine bay, for example, the air conditioning compressor 18. This air conditioning air compressor 18 can be fastened, bolted or otherwise joined with the frame member 2.
The fender 14 and frame 2 can be modified to accommodate the mirror mount 10 of the current embodiment. Specifically, the fender 14 and in particular the fender side 14S can be predrilled with a conventional drill to define holes 14H therein. When so drilled, the holes usually are of a circular shape. Likewise, the frame member 2 can be drilled to define holes 3H. These holes can be of the same size or of different sizes, and can be drilled by the same drill bit or different size drill bits. For example, the outer holes 14H can be of a first hole diameter H1 while the frame holes 3H can be of a second hole diameter H2. The second hole diameter H2 can be less than or smaller than the first diameter H1. With these optional different sized holes in the fender and frame, the pillars 140 can fit through the larger diametered holes 14H in the fender 14, yet abut against the frame outer wall 3 and in particular the frame exterior surface 3E, without projecting through the holes 3H. The fastener 50 can extend through the smaller holes 3H as described in more detail below, optionally without being threaded directly to those holes on the frame, as would be the case for example, with a self-tapping fastener.
As mentioned above, the mirror mount 10 includes a base 20. With reference to
The inner surface 22 of the base 20 can include an interior contour that follows the contours of the exterior surface 14E of the fender 14. The base 20 can be constructed so that the inner surface 22 engages substantially only the side surface 14S of the exterior 14E of the fender 14. In some cases, the fender 14 can include a particular indented or U-shaped contour 14C. Accordingly, the base 20 can include a corresponding projection 22C which is configured to fit within the contour or groove 14C. This can enable the base 20 to positively register with the fender, and particular physical contours of the fender, in a desired location along the exterior 14E.
The base 20 and the mirror mount 10 can be specifically configured so that they include no parts that extend upwardly over the fender upper edge 14U or otherwise into the engine bay 19 of the vehicle. Generally, the base and pillars can extend substantially only along the side surface 14S of the fender, and can terminate short of the upper edge 14U; hood 16 and engine bay 19. Optionally, the base can contact substantially only the side surface 14S and exterior surface 14E (including any contours 22C), without contacting or engaging other portions of the fender, such as the uppermost portion 14U and/or the other portions 14V and 14C.
The mirror 12 and support arm 30, can extend upward alongside the fender 14. Further, the base 20 and mirror mount 10 can be configured and sized so that they do not extend in any way adjacent the edge 17 of the hood, or higher than the uppermost portion 15 of the fender 14. The base 20 and mirror mount 10 can mount substantially entirely only on the side surface 14S of the fender 14.
Optionally, the base 20 can be configured to include a wheel well contour 22WW. This contour 22WW is specifically configured to accommodate an outer bulge in the fender 14 at the wheel well 14W. Generally the wheel well contour is of a concave shape as shown in
The base 20 of the mirror mount 10 can be constructed to include or be joined with a support arm 30. The support arm 30 can be of a multi-bar construction as shown. Alternatively, it can include a single arm. The support arm can include a proximal end 31 and a distal end 32. The distal end 32 is joined with a mirror 12. At the point of attachment of the distal end 32 to the mirror 12, a rotational element or swivel (not shown) can be included. That swivel can allow the mirror 12 to swivel relative to the support arm 30. The mirror can be any type of conventional mirror, and can include multiple different types of mirror surfaces.
The proximal end 31 of the support arm 30 can be joined with the base 20 via a mounting element 33. This mounting element 33 can include a pivoting structure such as bushings, a tube within a tube, and/or some other pivoting mechanism that allows the support arm 30, and thus the mirror 12, to move and optionally rotate relative to the base 20 and the fender 14 and/or vehicle 100. Further optionally, the mounting element 33 can include a breakaway mechanism so that it holds the support arm 30 and mirror 12 in a generally fixed position, unless and until the mirror and/or support arm 30 encounters an object which will push the support arm rearward so that it and the mirror are not damaged. Of course, the mounting element alternatively can be void of such a breakaway mechanism if desired.
As shown for example in
As shown in
The pillars can be of a substantially cylindrical shape, which optionally can be slightly tapered from the end closest to the base, that is, a first end 41, to a second end 42 (
The pillars 40 alternatively can be constructed to be non-integrally joined with the base 20. For example, they could be separate tubes (not shown) that include a threaded end and thread directly into the base 20. Further alternatively, the pillars 40 can be constructed to simply be in the form of fasteners extending from the base 20 as described further below in an alternative embodiment.
As shown in
With reference to
As shown in
As shown in
Generally, the pillars 40 can be constructed to engage the frame member 2, and for example, the outer wall 3 of the frame member, in such a way so that substantially all of the weight W of the base 20, the support arm 30 and the mirror 12 is transferred directly through the pillars to that frame member 2. Optionally, the weight of these components can create a moment M as shown in
As shown in
As shown, the fasteners can extend from the base 20 through the bore 44 of the pillars 40. In turn, the fasteners 50 also extend through the holes 14H in the fender 14, without ever contacting the fender due to the pillar disposed between the fastener and the hole around the pillar. The fasteners also can extend and protrude beyond the second end 42 of the pillars 40. The fasteners can be of a sufficient length so that they extend through the holes 3H of the frame member 2. In this manner, the fasteners 50 can extend through the outer wall 3. As shown in
Each fastener 50 can include or be joined with a nut 53. The nut 53 can be tightened on the fastener 50 to tighten, secure and rigidly mount the base 20 directly to the frame member 2. Optionally, the fastener 50 can create at least part of the clamping force CF between the nut 53 and the head 52 of the fastener to draw the base 20 and the respective pillars against the frame member 2. Further optionally, when the fastener 50 is installed and/or tightened, the pillars 40 can limit the movement of the base 20 toward the frame member 2. For example, the base 20 may be restricted from moving any closer than distance D1 to the frame member 2, and in particular the outer wall 3. In effect, this restriction of the movement can enable the pillars to prevent or impair the fender 14 from being crushed, dented, and/or permanently deformed if the nut 53 is over-tightened.
As mentioned above, the holes 14H and 3H can be predrilled in the respective fender and frame member. Holes 3H and the frame member can be drilled in locations that basically straddle a component within the engine bay 19. As shown in
To assemble the mirror mount 10 of the current embodiment, a user can join the mirror 12 with the support arm 30. The support arm 30 can be joined with the mounting element 33, and further secured to the base 20. The base 20 can be pre-manufactured to include integral pillars 40. Optionally, in some constructions, the pillars 40 can be connected to the base or otherwise brought into abutment with the base. A user can predrill holes 14H and 3H in the respective fender 14 and frame member 2. As mentioned above, the user can drill holes of different diameters H1 and H2 in the respective fender 14 and frame member 2. Optionally, the user can use a template that is provided with the mirror mount 10 to predrill the holes. The template generally can assist the installer in drilling the holes accurately and consistently from vehicle to vehicle and to ensure that the installer does not damage any components within the fender and/or engine bay.
The user can install the pillars 40 through the holes 14H and engage the second end 42 of the pillar in abutment with the upright wall 3 of the frame member 2. Optionally, this can result in the pillars 40 being generally orthogonal or perpendicular to the wall 3. With the pillars installed through the holes 14H and abutting the frame member 2, the user can install the fasteners 50 through the bores 44 in the pillars. The user can further install the nuts 53 on the opposing ends of the fasteners 50 and tighten them to rigidly and securely attach the mirror mount 10 to the frame member.
The second end 142 can be configured to include a shoulder 145. The shoulder 145 can be positioned adjacent a fastener 150 that is integrally formed with the pillar 140. This fastener 150 can be threaded. The fastener 150 also can be surrounded annularly by the shoulder 145. The shoulder 145 can transition inward from the outer surface dimension 140O of the pillar 140 down to the smaller outer surface dimension 150O of the fastener 150. The shoulder 145 can abut the exterior 3E around the hole 3H of the outer wall 3 of the frame member 2. Generally, the fastener 150 can extend through the frame member 2 so that a nut 153 can be tightened on the fastener 150 to secure the base 120 and the mirror mount 110 in general to the frame member 2 adjacent the fender 14, optionally, without pulling the fender 14 so much that the tightening dents or permanently deforms the fender.
A second alternative embodiment of the mirror mount 210 is generally shown in
When installed on a fender 14 as shown in
The fasteners 250 can be positioned in the bores 244 defined by the pillars 240 and optionally the support block 280. The fasteners 250 can further extend through the respective holes 14H of the fender 14 and the holes 3H of the frame member 2, similar to those of the embodiments above. The support block, however, is generally positioned in place by installing it through a lower portion of the fender 14 rather than through the holes 14H like the pillars 40, 140 of the other embodiments above. The pillars 240 included in this support block 280 can all be connected with one another. Although shown as having some structural differentiation, the pillars 240 alternatively can be formed simply as portions of the support block 280 with bores 244 strategically and specifically extending therethrough to accommodate respective fasteners.
In this construction, the support block 280 and the respective pillars 240 are configured to transfer forces created by the weight W of the respective components through the base 220 to the support block 280 and then to the frame member 2. Due to the disconnect between the support block 280 and the base 220, however, in some cases the fender 14 and in particular the side surface 14S can have forces transferred directly to and through it, from the base to the fender, to the support block. Further, in this construction, the fender 14 is sandwiched and clamped between the inner surface 222 of the base 220 and the outer surface 283 of the support block. The amount of clamping is dictated by how tight the fasteners 250 are fastened and/or tightened, as well as the overall length L of the support block. This length L can be of a preselected distance that is equal to or slightly greater or lesser than the distance between the inner fender surface 141 and the frame exterior 3E. When slightly less, the base 220 can further clampingly engage the fender and draw it closer to the frame 2—but optionally not so close that is dents or deforms the fender.
