Backaround Art:

As~opera~or~ are aw~re,~vebicl-~u--d~or carryino : :;loads~and towing, wheth~r they;be auto;mobiles, pick-up trucks, vans-cr the like, fr~equently~have a conventional ~: ` : : :

, ~ide view mirror which does not e~able the driver to see to the rear. This i9 particularly ~o where, for instance, an extra wide tow or load i~ involved such as a boat trailer, trailer home, camping trailer or high and wide load of whatever nature. Campers on the beds of pick-up trucks are another exam~le. These loads are most often not only wide but long and the standard side mounted mirror simply doe3 not permit an adequate line of vision to the rear of the load or tow. In addition there is the ~roblem of blurring caused by vibration of the mirror on its mounting.
One solution with which many drivers are familiar is the extended mirror mounting frame which holds the mirror far enough away from the side of the vehicle so that the driver can observe to the rear of his load or tow.
Typically, the extra vide or extended mirror mount~ are a three point support frame structure attached to the out~ide of~eAch front door panel.~ Unlike many if not most conventional mirror mounts whlch are rotatable or can fold ~, ~
back,~the three point support frame is fixed. If the ratatable mount is accidentally struck, it will collapse or fold back without damage to itself or to the door panel.

One solution is to change back to the conventional mirror mount when the vehicle is not being used to carry a load or to tow. However, changin~ mirror mounts is time consumin~, tediou~ and fru~trati1lg.
The broad concept o~ a laterally adju~table mirror, from a Sirst position near the door window to an outer or exeended ~econd poeition to establi~h a line of vision rearwardly of a load or tow, is old. In United States Patent No. 4,165,156 to O'Connell a fold back mountin~
frame bracket is used together with a pivot arm for the m1rror. The structure allows the mirror to be at a ,:
conventional distance from the driver's window. It al80 al10ws the driver to pivot the mirror to an outer position thus enabling him or her~to ~e~ behind a load or tow.
Another structure for horizontal outward adjustment o~
a vehic1e~mirror is Sound 1n UnIted States~Patent No.

In United States Paten~ No. 4,558,930 to Deedreek an outwardly extendible mirror 1~ provided by a motor driven rack and pinion. The mirror itself i5 also pivotable with an electric motor driven set of gears. Again, the structure is unrelated in principle or design to the instant device.
United States Patent No. 4,247,173 to ~talone shows another structurally unrelated system for extendin~ and retracting an outside rear view mirror. Briti~h Patent Specification ~99,802 shows a very complicated and prohibitively expensive structure for laterally extendin~
and retracting a mirror but it is not pertinent to the invention herein. Unit~d States Patent No. 4,451,021 to Merriss shows a simple slotted slide bar which is secured by a bolt to the upper part of the door panel bracket.
Again, however, it is not material to the invention herein.
United States Patent No. 4,711,538 shows an entirely different method of supportin~ the slidable and adjustable mirror mount which i8 similar to but distinct from the invention of this~application. United States Patent Numbe~s 4,315,61~ and 3,048,084 are of intere~t but structurally and functionally completely dif~erent from the instant device.

Summary of the Invention The invention comprises a structure which utilizes an existing door panel mirror mounting fr~me or support. One type of door panel mounted su~port includes a curved or arcuate neck part which neck is cut as by hacksaw a predetermined distance above the top of the support. The upwardly extending stub is provided with an adapter arm in which is mounted a slidable mirror mounting block. The lidably adjustable block has a slot therein by ~hich it is received on the adapter arm. A cavity on the upper surface of tbe block receives tbe mirror support neck by being -~
inserted in the cavity and then tightened in position.
Alternatively the block can be made in two parts and installed on the upper horizontal~bar portion of an existin~ bracket.
~ Accordin~ly, it i8 among the~many eaeures of the " ~ invention to provide a horizontally adjustable and repo~itionable exterior ~ide view mirror support structure -which i~ uniquoly simple, inexpensive, ru~ed~and durable.
The mirror ~upport device allow~ the vehicle owner to .
~ S

rl ~r~
utilize the existing mounting mea~s ~uch that the mirror itself is disconnected from the ori~in~l support and replaced on the support ~structure of this invention. No special tools are required to install the device and it i5 not necessary to drill any holes. The block can ~e mounted on an adapter arm or on the uppex horizontal portion of a support frame. The invention is designed to be tamper proof and retains the advantage of using the original mirror support struct~lre mounted on the door panel.

Brief DescriDtion of the Drawinas Figure 1 is a view in perspective showin~ a standard type of door panel mountin~ structure for an exterior mirror, ':
Figure 2 is a view in perspective of the mirror of Fi~ure 1 removed by cuttin~ throu~h the curved necX and then sub!stituting for the neck stub a replacement sleeve, and Fi~ure 3 is a view in cro~s section showing the replacement sleeve in position in the support base after the neck stub i~s removed.

Best ~ode_For Carryin~ Out ~he Invention Referring now to the drawin~s it will be seen that Fi~ure 1 represents a standard type o~ side view mirror mount for a vehicle such as a Chevrolet pick-up truck or , van. In this regard~see co-pendin~ United State~ Patent Application Serial No. 128,056 ile~ December 3, 1987.
Mirror M is connected by curved tubular support neck member 12 to the mountinq base 14 attached to the door panel. The support bas~ 14 itself, reference~ being made to Figures 2 and 3 of the drawings, show that the original neck 12 ~-~
exeeDd downwardly lnto the support base where it is securely held in place.
Support 14, which forms no part of the invention : :
, ~ , :
herein, i8 original equipment by the manufacturer as di-cu-sed in~copending Appllc~tlon~Serial~No. 128,05~. -Su~port 14~has a rèmovable~cover~16 and a moun~tin~ base 18 ; attached ~to the vehicle door. The mounting base 1~ ;
ncludes a~mountin~structure~;20;~having a~roughly semi-c:ircular cradle member 22 uhich includes a retainer ridge ~: ~ : : ~ : : :
~ 24. A clamp ~art 26 has two detent extensions (not shown) : :
~: 7 - 2~C~V~

along one edge whlch are inserted into the cradle structure 20. The other edge of the clamp part 26 ha# a flat lip 28 which i~ secured to the cradle structure by bolts 30.
To install the invention of this application the neck support 12 is cut a predetermined distance, such as 3/8 inch, above the support level as by hacksaw or ~he like 80 ~ that a stub 23 is left in support 14. Because o :~
~:~ variations in diameter of the necks 12 it has been found : desirvu~ to remove the stub 23 by removing the cover 16 and loosening the clamp portion 26 in the manner now to be : described.
:: :
An adapter support bar, generally designated by the : :number 40, and as can:best be seen in Figure 2, is an elongated rectangular bar~approximately 1/4 inch thick by approximately 6 inches in length and about 1 inch in width.
: Bar~ 40~has inner~end 42 and outer end 46 and near inner end 4~2~is provided with:a round open~ing 48. :Bar 40 has at east~ one recessed lock screw 44 ~which in our copending applic;ation wàs for the~purpose of securing bar 40 to stub ; ~3.
An~adjustable mirror moun~ing block,~ generally ~ :: : ::: : :
~ ~ designated by the number 50, i8: ~generally rectangular ~ , ~
having inner and outer ends 52 and 54 respectively, top :
: ;: 8 surface 57, bottom surface 59, and front and rear sides 60 and 62 respectively. Top surface 57 is generally planar and includes opening 55 therein which extends downwardly to a bottom cavity surface to receive the arcuate or curved neck support member 12. Recessed lock screws 58 are receiv d in threaded holes from each side surface 60 and 62 or from front side surface 60 as ~hown to hold neck 12 rigidly in position in the opening 55. Below the openin~
55 in the body of block 50 is a slot 64 to receive adapter bar 40. It will be appr ciated that an adjustment screw 56 extends into the block from the rear ~ide edge 60 of the block to engage the bar. The adjustment screw 66 has a knurled finger knob so that the screw can be released easily and the block 50 moved to its desired location on the bar. Stop means 45 are provided at the outer end of bar 40 so that block 50 cannot be slidably removed from the bar.
As mentioned above the cradle structure of the support base includes a retainer rid~e a4. In place of the stub 23, a tubular replacement sleeve 70 o~ predetermined length and diameter i9 provided. It has an upper end 72, a lower end 74 and is of a consiAtent diameter and wall thickness so that ~roove 76 can be formed therein to coincide with retainer ridge 24 so that the entire mirror mounting assembly cannot be pulled out except by dismantling the support base 14. Once the replacement sleeve i5 substituted for the stub 23, the clamp is resecured and the cover 16 placed back in position. Then the arm 40 can be mounted, the neck support 12 inserted and secured to block 50 and the adjustable mirror mount is in place. It will be appreciated that the entire neck may be removed from the support base before it is cut and then the cut made according to dimensions needed.
