Description
CA 02090~02 1997-10-31 VEHICULAR MIRROR CLAMPING BRACKET
BACKGROUND OF THE INVENTION
1. Field of the Invention:
The present invention relates to a clamping bracket for securing a mirror assembly to a vehicle.
BACKGROUND OF THE INVENTION
1. Field of the Invention:
The present invention relates to a clamping bracket for securing a mirror assembly to a vehicle.
2. Prior Art:
A vehicle mirror must add to the ability of the vehicle operator to operate the vehicle safely. Therefore, it is generally preferred that the mirrors above the front of the vehicle permit the driver to (1) easily locate the mirror, (2) view objects from in front of the mirrors, and (3) view objects to the side and rear of the vehicle. Numerous mirror mounting supports are known for securing a mirror to the vehicle.
For example, U.S. Patent No. 1,932,873, issued to Dujardin on July 3, 1934, discloses a support for a rear view mirror positioned on the front of a vehicle which is capable of holding the mirror in position, the mirror having the capability to be adjusted vertically and horizontally. The support directly mounts to the vehicle without any provision to dampen vibrations and eventual distortion of the mirror adjustment.
U.S. Patent No. 3,395,883, issued to Murgas on August 6, 1969, discloses a detachable vehicle fender mirror support which is independent of the mirror and mirror support until assembled.
The fender support is a tripod attached to a "Y" shaped clamp which attaches to the top inside edge and uppermost wheel housing edge of the fender. The design of the fender support makes limited provision for dampening vibrations, does not provide for mlrror adjustment, and limits the locations for installing the mlrror .
U.S. Patent No. 4,500,063, issued to Schmidt and Hutchinson on February 19, 1985, discloses a fender mount for a rear view mirror attachable to the front curved corner of the fender and a CA 02090~02 1997-10-31 cover detail which secures the lower portion of the tubular steel shaft into the base member. This mounting assembly is an improvement over previous methods, but it is limited in its positioning use. Also, it requires periodic tightening to prevent the tubular mirror support shaft from escaping and vibrating.
Another problem with prior art supports is their failure to address vibration. A chronically vibrating reflecting surface of a mirror becomes ineffective and does not aid the operator. The assembly of the mirror is generally elongated to accommodate for the mirror's viewing height, essentially increasing the likelihood of chronic mirror vibration.
During the course of their work with vehicle mirror accoutrements, the present applicants invented a single mount unit clamping bracket. It was determined that the torque being applied to the tubular shaft supporting the mirror by the single mount unit clamping bracket was being limited by the mating surface between the clamping portion of the bracket and the base portion of the bracket. This application addresses the torque limitation of the bracket.
Furthermore, prior art devices are restrictive in their use and require continuous service to prevent vibrating and unassisted gross movement by the mirror and supporting shafts.
It would be desirable to provide a clamping bracket which is a single detail, usable for clamping the mirror to the support tubular shaft and the mirror assembly to the vehicle; not adjustable by screws, self-torquing of the tubular shaft; capable of rotating adjustment; and not restricted to mounting location on the vehicle.
SU~M~RY OF T~ INVFNTION
The clamping bracket of the present invention is used in combination with vehicle mirror assemblies. The clamping bracket hereof generally comprises:
CA 02090~02 1997-10-31 (a) a base, the base having a latch side and a hinge side, the base having a radially shaped concave channel formed therein proximate the latch side, the concave channel having a first radius of curvaturei (b) a clamp, the clamp having a hinge side and a hook side, the hinge side of the clamp being integrally formed with the hinge side of the base, the clamp having a radially shaped convex portion proximate the hook side, the radially shaped convex portion having a second radius of curvature, the second radius of curvature being different than the first radius of curvature, the convex portion being seatable within the concave channel;
(c) means for opening and closing the clamp;
(d) means for latching the bracket; and wherein the base and the clamp cooperate to define a unit, the unit having a throughbore therein and, upon latching the clamp to the base, the convex portion and the concave channel are in a spaced part relationship such that a continuous torque is maintained on the tubular support.
The clamping bracket is designed to receive a mirror assembly support, usually a tubular support, within the throughbore. The tubular support is secured in position when the clamp is latched. A concave channel is formed within the top surface of the base between the means for latching and the throughbore. The channel extends from one end of the bracket to the opposite end. The channel provides a clearance for the clamp to apply torque to the tubular support when latched.
The clamping bracket also provides for optional shapes on the bottom surface of the base. The type of mounting surface dictates the shape of the bottom surface. This allows clamping brackets to be mounted on flat surfaces as well as on rounded surfaces.
Other attendant advantages will be more readily appreciated as the same become better understood by reference to the detailed description and considered in connection with the accompanying CA 02090~02 1997-10-31 drawings, in which like reference numerals designate like parts throughout the figures, in which:

Referring now to the drawings and in particular to Figs.
1-5, there is depicted one embodiment of the vehicular mirror clamping bracket of the instant invention shown, generally, at 1.
The vehicular mirror clamping bracket 1 comprises:
(a) a base 3, the base 3 having a hinge side 19 and a latch side 17;
(b) a clamp 5, the clamp 5 having a hinge side 29 and a hook side 31, the hinge side 29 of the clamp 5 being integrally formed with the hinge side 19 of the base 3;
(c) means 37 for opening and closing the clamp 5;
(d) means 7 for latching the bracket 1 such that the clamp 5 can be locked and unlocked;
(e) means for mounting 10 the bracket 1 to a mounting surface 49; and wherein the base 3 and the clamp 5 define a unitary member 43, the unitary member 43 having a throughbore 41 formed therein.
CA 02090~02 1997-10-31 The base 3 of the clamping bracket 1 comprises a mounting member 45 having a first end 51 and a second end 53. The base 3 having at least one aperture 15 on each side 19, 17 of the base 3 for inserting a means for mounting to the bracket 1 such as a bolt and nut assembly or the like.
The base 3 further comprises a top surface 21 and a bottom surface 9. The top surface 21 includes a radially shaped concave channel 39 which extends from the first end 51 of the base 3 to the second end 53. The channel 39 is located between the throughbore 41 and the means for latching 7 on the latch side 17 of the top surface 21 of the base 3 and provides the necessary clearance for the clamp 5 to apply torque to a mirror assembly support 47.
The clamp 5 comprises a hinged member 35. The hinged member 55 has a first end 57 and a second end 59. The hinged member includes a convex shaped outside surface 61 from a hinge point 35 to a point 65 opposite the hinge point 35. The surface 61 is concentric with the throughbore 41. The outside surface 61 continues as a concave shaped surface 63 from the opposite point 65 to the hook side 29 of the clamp. The convex shaped 61 and concave shaped 63 outside surfaces extend from the first end 57 of the clamp 5 to the second end 59.
Also, as shown in Figs. 1, 2, 3, 4, and 5, the clamp member 5 also includes an inner surface 62. The inner surface 62 has a radially shaped convex portion 64, proximate the hook member 71 and opposite the outside concave surface 63. The convex portion 64 is seatable within the convex channel 39 when the clamp 5 and the base 3 are engaged or locked. The convex portion 64 has a second radius of curvature and the concave channel 39 has a first radius of curvature, the second radius of curvature being different from the first radius of curvature. The differences in curvature cause a spatial relationship or clearance space 66 to remain between the convex portion 64 and the concave channel 39 when the clamp 5 is engaged or locked to the base 3.
CA 02090~02 1997-10-31 The means for hinging 37 the clamping bracket 1 comprises a "v" shaped notch 33 formed on the inside surface 67 of the throughbore 41. The "v" shaped notch 33 is located at the hinge point 35 where the hinge side 29 of the clamp integrally connects with the base 3. The "v" shaped notch 33 permits the clamp 5 to be opened and closed, as shown in Figs. 4 and 5.
The means for latching 7 provides for locking the clamp 5 to the base 3 in a closed position, as shown in Fig. 5. The means for latching 7 comprises: a latching slot 23, formed in the top surface 21 of the base 3. The latching slot 23 is located medially of the clearance channel 39 and the aperture 15 and extends from the first end 51 of the base 3 to the second end 53.
The latching slot 23 has a latching edge 25 which partially projects over the slot 23 to provide an edge 25 for the means 7 for latching to interengage. The latching edge 25 is integrally formed to the top surface 21 of the base 3 proximate to the edge 69 of the clearance channel 39.
The means 7 for latching further comprises a latch hook 27 which is integrally connected to the clamp 5. The latch hook 27 projects normal from the hook side 31 of the clamp 7 and extends from the first end 57 of the clamp 7 to the second end 59. The latch hook 27 latches under and urges against the latching edge 25 of the base 3 when the clamp 5 is in a closed position, as shown in Fig. 5.
The latch hook 27 includes a hook member 71 and a support member 73. The hook member 71 is wedge shaped and is integrally formed with the support member 73. The hook member 71 extends from the first end 57 of the clamp to the second end 59. The support member 73 is integrally formed with the hook member 71 at one side and the hook side 31 of the clamp 5 at the other side.
The support member 73 is an elongated rectangular bar shape extending from the first end 57 of the clamp 5 to the second end 59. The slot 23, latching edge 25 and latch hook 27 cooperate to define the means 7 for latching the clamp 5 to the base 3.
CA 02090~02 1997-10-31 The means for mounting ~not shown) comprises a plurality of fasteners, such as a bolt and nut or the like, which fastens the clamping bracket 1 to a vehicle mounting surface 49.
The preferred bottom mounting surface 9 of the mounting member 45 is a flat surface from the hinge side 19 of the base 3 to the latch side 17 and from the first end 51 of the base 3 to the second end 53, as shown in Figs. 1-5.
A second embodiment of the clamping bracket 1, shown in Fig.
6, has a horizontal concave bottom mounting surface 79 which extends from the hinge side 19 of the base 3 to the latch side 17. This embodiment permits the bracket 1 to be mounted to a convex surface.
Another embodiment of the clamping bracket 1 has a vertical concave bottom mounting surface which extends from the first end 31 of the base 3 to the second end 53. This embodiment also permits the clamp bracket 1 to be mounted on a convex surface.
The typical vehicular clamping bracket 1, as illustrated in Fig. 1, is used to assemble a mirror 11 and the tubular support 47 and a fender mounting bracket 13. The clamping bracket 1 clamps the tubular support 47 firmly in place by interconnecting the latch hook 26 with the latch edge 25. The latched clamp 5 maintains a continuous torque on the tubular support without the use of an independent fastening means.
In summary, there has been disclosed a vehicular clamping bracket 1 comprising one piece instead of two, but providing a continuous torque on the tubular support 47 by using a single clamping latch with no adjustment needed instead of a fastening means that requires constant adjustment. The instant invention can be used in more than one application within the vehicular mirror assembly.
Having, thus described the invention, what is claimed is:
A vehicle mirror must add to the ability of the vehicle operator to operate the vehicle safely. Therefore, it is generally preferred that the mirrors above the front of the vehicle permit the driver to (1) easily locate the mirror, (2) view objects from in front of the mirrors, and (3) view objects to the side and rear of the vehicle. Numerous mirror mounting supports are known for securing a mirror to the vehicle.
For example, U.S. Patent No. 1,932,873, issued to Dujardin on July 3, 1934, discloses a support for a rear view mirror positioned on the front of a vehicle which is capable of holding the mirror in position, the mirror having the capability to be adjusted vertically and horizontally. The support directly mounts to the vehicle without any provision to dampen vibrations and eventual distortion of the mirror adjustment.
U.S. Patent No. 3,395,883, issued to Murgas on August 6, 1969, discloses a detachable vehicle fender mirror support which is independent of the mirror and mirror support until assembled.
The fender support is a tripod attached to a "Y" shaped clamp which attaches to the top inside edge and uppermost wheel housing edge of the fender. The design of the fender support makes limited provision for dampening vibrations, does not provide for mlrror adjustment, and limits the locations for installing the mlrror .
U.S. Patent No. 4,500,063, issued to Schmidt and Hutchinson on February 19, 1985, discloses a fender mount for a rear view mirror attachable to the front curved corner of the fender and a CA 02090~02 1997-10-31 cover detail which secures the lower portion of the tubular steel shaft into the base member. This mounting assembly is an improvement over previous methods, but it is limited in its positioning use. Also, it requires periodic tightening to prevent the tubular mirror support shaft from escaping and vibrating.
Another problem with prior art supports is their failure to address vibration. A chronically vibrating reflecting surface of a mirror becomes ineffective and does not aid the operator. The assembly of the mirror is generally elongated to accommodate for the mirror's viewing height, essentially increasing the likelihood of chronic mirror vibration.
During the course of their work with vehicle mirror accoutrements, the present applicants invented a single mount unit clamping bracket. It was determined that the torque being applied to the tubular shaft supporting the mirror by the single mount unit clamping bracket was being limited by the mating surface between the clamping portion of the bracket and the base portion of the bracket. This application addresses the torque limitation of the bracket.
Furthermore, prior art devices are restrictive in their use and require continuous service to prevent vibrating and unassisted gross movement by the mirror and supporting shafts.
It would be desirable to provide a clamping bracket which is a single detail, usable for clamping the mirror to the support tubular shaft and the mirror assembly to the vehicle; not adjustable by screws, self-torquing of the tubular shaft; capable of rotating adjustment; and not restricted to mounting location on the vehicle.

Referring now to the drawings and in particular to Figs.
1-5, there is depicted one embodiment of the vehicular mirror clamping bracket of the instant invention shown, generally, at 1.
The vehicular mirror clamping bracket 1 comprises:
(a) a base 3, the base 3 having a hinge side 19 and a latch side 17;
(b) a clamp 5, the clamp 5 having a hinge side 29 and a hook side 31, the hinge side 29 of the clamp 5 being integrally formed with the hinge side 19 of the base 3;
(c) means 37 for opening and closing the clamp 5;
(d) means 7 for latching the bracket 1 such that the clamp 5 can be locked and unlocked;
(e) means for mounting 10 the bracket 1 to a mounting surface 49; and wherein the base 3 and the clamp 5 define a unitary member 43, the unitary member 43 having a throughbore 41 formed therein.
CA 02090~02 1997-10-31 The base 3 of the clamping bracket 1 comprises a mounting member 45 having a first end 51 and a second end 53. The base 3 having at least one aperture 15 on each side 19, 17 of the base 3 for inserting a means for mounting to the bracket 1 such as a bolt and nut assembly or the like.
The base 3 further comprises a top surface 21 and a bottom surface 9. The top surface 21 includes a radially shaped concave channel 39 which extends from the first end 51 of the base 3 to the second end 53. The channel 39 is located between the throughbore 41 and the means for latching 7 on the latch side 17 of the top surface 21 of the base 3 and provides the necessary clearance for the clamp 5 to apply torque to a mirror assembly support 47.
The clamp 5 comprises a hinged member 35. The hinged member 55 has a first end 57 and a second end 59. The hinged member includes a convex shaped outside surface 61 from a hinge point 35 to a point 65 opposite the hinge point 35. The surface 61 is concentric with the throughbore 41. The outside surface 61 continues as a concave shaped surface 63 from the opposite point 65 to the hook side 29 of the clamp. The convex shaped 61 and concave shaped 63 outside surfaces extend from the first end 57 of the clamp 5 to the second end 59.
Also, as shown in Figs. 1, 2, 3, 4, and 5, the clamp member 5 also includes an inner surface 62. The inner surface 62 has a radially shaped convex portion 64, proximate the hook member 71 and opposite the outside concave surface 63. The convex portion 64 is seatable within the convex channel 39 when the clamp 5 and the base 3 are engaged or locked. The convex portion 64 has a second radius of curvature and the concave channel 39 has a first radius of curvature, the second radius of curvature being different from the first radius of curvature. The differences in curvature cause a spatial relationship or clearance space 66 to remain between the convex portion 64 and the concave channel 39 when the clamp 5 is engaged or locked to the base 3.
CA 02090~02 1997-10-31 The means for hinging 37 the clamping bracket 1 comprises a "v" shaped notch 33 formed on the inside surface 67 of the throughbore 41. The "v" shaped notch 33 is located at the hinge point 35 where the hinge side 29 of the clamp integrally connects with the base 3. The "v" shaped notch 33 permits the clamp 5 to be opened and closed, as shown in Figs. 4 and 5.
The means for latching 7 provides for locking the clamp 5 to the base 3 in a closed position, as shown in Fig. 5. The means for latching 7 comprises: a latching slot 23, formed in the top surface 21 of the base 3. The latching slot 23 is located medially of the clearance channel 39 and the aperture 15 and extends from the first end 51 of the base 3 to the second end 53.
The latching slot 23 has a latching edge 25 which partially projects over the slot 23 to provide an edge 25 for the means 7 for latching to interengage. The latching edge 25 is integrally formed to the top surface 21 of the base 3 proximate to the edge 69 of the clearance channel 39.
The means 7 for latching further comprises a latch hook 27 which is integrally connected to the clamp 5. The latch hook 27 projects normal from the hook side 31 of the clamp 7 and extends from the first end 57 of the clamp 7 to the second end 59. The latch hook 27 latches under and urges against the latching edge 25 of the base 3 when the clamp 5 is in a closed position, as shown in Fig. 5.
The latch hook 27 includes a hook member 71 and a support member 73. The hook member 71 is wedge shaped and is integrally formed with the support member 73. The hook member 71 extends from the first end 57 of the clamp to the second end 59. The support member 73 is integrally formed with the hook member 71 at one side and the hook side 31 of the clamp 5 at the other side.
The support member 73 is an elongated rectangular bar shape extending from the first end 57 of the clamp 5 to the second end 59. The slot 23, latching edge 25 and latch hook 27 cooperate to define the means 7 for latching the clamp 5 to the base 3.
CA 02090~02 1997-10-31 The means for mounting ~not shown) comprises a plurality of fasteners, such as a bolt and nut or the like, which fastens the clamping bracket 1 to a vehicle mounting surface 49.
The preferred bottom mounting surface 9 of the mounting member 45 is a flat surface from the hinge side 19 of the base 3 to the latch side 17 and from the first end 51 of the base 3 to the second end 53, as shown in Figs. 1-5.
A second embodiment of the clamping bracket 1, shown in Fig.
6, has a horizontal concave bottom mounting surface 79 which extends from the hinge side 19 of the base 3 to the latch side 17. This embodiment permits the bracket 1 to be mounted to a convex surface.
Another embodiment of the clamping bracket 1 has a vertical concave bottom mounting surface which extends from the first end 31 of the base 3 to the second end 53. This embodiment also permits the clamp bracket 1 to be mounted on a convex surface.
The typical vehicular clamping bracket 1, as illustrated in Fig. 1, is used to assemble a mirror 11 and the tubular support 47 and a fender mounting bracket 13. The clamping bracket 1 clamps the tubular support 47 firmly in place by interconnecting the latch hook 26 with the latch edge 25. The latched clamp 5 maintains a continuous torque on the tubular support without the use of an independent fastening means.
In summary, there has been disclosed a vehicular clamping bracket 1 comprising one piece instead of two, but providing a continuous torque on the tubular support 47 by using a single clamping latch with no adjustment needed instead of a fastening means that requires constant adjustment. The instant invention can be used in more than one application within the vehicular mirror assembly.
