Abstract:
A foldable mirror assembly used to assist an operator to align a hitch on a trailer to the hitch of a vehicle while hitching a vehicle to a trailer, consisting of a base for mounting to the rear of a vehicle, support arms that pivot upwards and outwards to the rear of the vehicle, that support a convex mirror that is angled to give the operator a line of sight to the rear of the vehicle. The support and mirror components fold substantially flat to the base which enables the base to remain installed on the rear of the vehicle in the closed position while not in use. Alternatively, The assembly can be removably attached, and therefore folded to the closed position, and then removed and stored after using.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention relates generally to a visual aid device, and more particularly, it relates to a mirror assembly used to assist an operator to align a hitch on a trailer to the hitch of a vehicle. 
         [0002]    It is often difficult for an operator to precisely align a trailer hitch with the receiving hitch of a tow vehicle so as to enable the attachment of the trailer to the vehicle. Because there is no direct visual sightline from the operator&#39;s seat of the tow vehicle to the rear of the vehicle where the receiving hitch is positioned, there is no means for the operator alone to align the trailer hitch with the receiving hitch without the operator getting out of the vehicle a multiple number of times to determine the position of the receiving hitch of the vehicle relative to the position of the trailer. If a second person is not available to assist the operator, the process of aligning the trailer hitch with the receiving hitch of the vehicle alone usually involves the operator getting out of the vehicle frequently to determine how to maneuver the vehicle and repeated unsuccessful attempts at backing the tow vehicle towards the trailer. Not only is the process of aligning and connecting a tow vehicle to a trailer without assistance generally frustrating and time consuming, it is also potentially dangerous to the operator who is repeatedly exiting the vehicle, sometimes near traffic. Back injuries are also not uncommon when the tow vehicle hitch is not close enough to the trailer hitch and the operator needs to manually move the trailer hitch to the hitch on the vehicle. 
         [0003]    Typically, the assistance of a second person is required to effectively and safely align the hitches. Usually, the second person stands behind the tow vehicle and directs the operator by way of hand signals and loud verbal communication to back the vehicle towards the trailer. Such two person method, although commonly used and arguably more effective than the operator attempting to align the hitches alone, still poses potential harm, especially to the second person standing behind the tow vehicle, who risks being crushed or otherwise hit by the vehicle. 
         [0004]    In addition to potential damage to the operator and/or the second person, the conventional methods of aligning and connecting hitches described above may also cause damage to the trailer and/or tow vehicle hitches. Most hitches virtually need to be oriented precisely on top of the other in order to properly and securely couple together. Some hitches may be manually lifted to connect the trailer with the tow vehicle if the tow vehicle is not backed close enough to the trailer. Many larger trailers are too heavy to be manually manipulated or nudged into proper alignment for coupling, so an exact alignment is especially crucial in such cases. Quite often, because the hitches need to be so precisely aligned and in close proximity to each other, damage occurs to either (or both) the trailer hitch or the rear of the tow vehicle due to the operator backing up too far. 
         [0005]    Various devices have been provided to facilitate the connecting of a tow vehicle to a trailer. For example, U.S. Pat. No. 6,102,423 to Beck et al. describes a detachable visual alignment aid for connecting the ball of the hitch on a towing vehicle to the socket on the tongue of the trailer. U.S. Pat. No. 6,022,116 to Osborn discloses a support device for temporarily supporting a mirrored surface from a tow vehicle, the device being mountable near the tow attachment in order to allow the viewing of the towing coupling while connecting the towing coupling to an object to be towed. U.S. Pat. No. 5,971,555 to Wilcox et al. discloses a hitch viewing mirror assembly comprising a U shaped perimeter frame and a planar mirror pivotally mounted to the frame wherein the frame is mountable to a vehicle by a plurality of suction cups mounted at various locations along the frame. The problem with such prior art hitching devices is that they describe detachable mirror assemblies that require inconvenient re-mounting on the vehicle and/or readjusting every time the device is put to use. The prior art hitching devices are designed to be removed from the tow vehicle when not in use and need to be properly stored, whether in the vehicle, in the garage, or any other suitable storage location, to prevent damage until next use. As such, the prior art hitching devices are not conveniently and immediately readily available for use when required because they need to be located and retrieved from storage and mounted on the vehicle and/or adjusted prior to use. 
         [0006]    Other prior art hitching devices disclose the use of stanchion poles as markers placed on the hitches but such are time consuming to set-up and need to be stored, therefore they are not readily available for use. Other more complex devices include electronic sensors or cameras with displays mounted in the tow vehicle to visually or audibly aid the alignment process. These complex devices are costly and require extensive modification to the tow vehicle in their installation. Furthermore, sensitive electronics are potentially vulnerable to malfunction due to dirt, corrosion, and destructive conditions due to foul exterior road elements that could inhibit their effective use. 
         [0007]    None of the aforementioned patents disclose a reliable foldable mirror assembly for hitching trailers that is immediately available for use without mounting or adjustments. In this respect, the present invention substantially departs from the conventional concepts and designs of the prior art. A need for an improved hitching device therefore exists. 
       BRIEF SUMMARY OF THE INVENTION 
       [0008]    It is an object of the invention to provide a foldable mirror assembly for hitching trailers that may remain attached to the towing vehicle. 
         [0009]    It is a further object of the invention to provide a foldable mirror assembly for hitching trailers suitable for all types of vehicles having a towing hitch.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0020]    With reference to  FIGS. 1 to 7 , a foldable mirror assembly  50  for hitching trailers comprises a base  1 , a first and a second support arm  2   a ,  2   b  each pivotably coupled with base  1  at a first end, and a mirror  4  mountable on a support  3  wherein support  3  is pivotably coupled with a second end of each first and second support arms  2   a ,  2   b.    
         [0021]    Base  1  may be made of any durable material suited for outdoor use such as but not limited to aluminum, stainless steel, fiberglass, or plastic. Preferably, base  1  is made of injection molded plastic. Base  1  further comprises at least one attachment means configured to attach base  1  to the rear of a vehicle  7  in a manner best seen in  FIGS. 1 ,  3 , and  4 . Base  1  may be attached to the rear of virtually any vehicle, such as but not limited to pick up trucks (with or without canopies, box covers, or dry boxes), cars with hatches or trunks, sport utility vehicles, and vans. Suitable attachment means for attaching base  1  of foldable mirror assembly  50  to the rear of vehicle  7  include but are not limited to hooks, screws, magnets, two-sided adhesive, hook and loop fasteners, and suction cups. In the preferred embodiment, base  1  is secured to the rear of vehicle  7  such that foldable mirror assembly  50  may remain attached to vehicle  7  without the need to be removed when not in use, whether vehicle  7  is in motion or stationary. In such preferred embodiment, foldable mirror assembly  50  may be permanently attached or remain detachably attached to vehicle  7  without affecting the functioning or interfering with drivability of vehicle  7 , as described in greater detail below. In an embodiment of the invention, foldable mirror assembly  50  may be incorporated into the manufacture of vehicle  7  as a fixed installation. Alternatively, foldable mirror assembly  50  may be an after market installation that may be fixedly mountable with the rear of vehicle  7 . In the further alternative, foldable mirror assembly  50  may be an after market installation detachably mounted with the rear of vehicle  7 . Preferably, foldable mirror assembly  50  may be securely attached with vehicle  7  by suitable attachment means such as suction cups, two-sided adhesive, or magnets or the like such that foldable mirror assembly  50  may remain secured to vehicle  7  when not in use and foldable mirror assembly  50  may be detached from vehicle  7  only if desired without permanently damaging, altering or otherwise affecting the exterior of vehicle  7  when detached. 
         [0022]    In a preferred embodiment of the invention, base  1  is generally U-shaped although base  1  may be of any shape or configuration as long as it may receive support  3  and first and second support arms  2   a ,  2   b  in a substantially flat configuration, as described in greater detail below. As best seen in  FIGS. 1 ,  3 , and  4 , base  1  may be attached with the rear of vehicle  7  so as not to interfere with the usual location of most tailgate latches  30  and trunk keyholes  31  on vehicle  7 . In the preferred embodiment, base  1  is attached with the rear of vehicle  7  such that tailgate latch  30  and trunk keyhole  31  are disposed in between a first and second side  20 ,  22  of base  1  within the void defined by the U-shape of base  1 , as best seen in  FIG. 1 . 
         [0023]    Base  1  preferably comprises a plurality of recesses configured to receive first and second support arms  2   a ,  2   b  and support  3  when foldable mirror assembly  50  collapses from the first open position, as best seen in  FIGS. 1 and 6 , to the second closed position, as best seen in  FIG. 5 . For greater clarity, each of first and second sides  20 ,  22  of base  1  may be recessed to form support arm depressions  23  conforming to the shape and configuration of support arms  2   a ,  2   b  such that when support arms  2   a ,  2   b  collapse from the first open position to the second closed position, support arms  2   a ,  2   b  may be received and retained in support arm depressions  23  in a substantially flat configuration. Similarly, a third side  24  of base  1  may be recessed to form support depression  16  conforming to the shape and configuration of support  3  such that when support  3  collapses from the first open position to the second closed position, support  3  may be received and retained in support depression  16  in a substantially flat configuration. Support arm depressions  23  and support depression  16  are recessed so as to protect first and second support arms  2   a ,  2   b  and mirror  4  mounted on support  3  and to effectively reduce the overall thickness of foldable mirror assembly  50  when stowed on vehicle  7  in the second closed position. 
         [0024]    As best seen in  FIG. 6 , first and second support arms  2   a ,  2   b  are preferably pivotably coupled with first and second sides  20 ,  22 , respectively, by way of a first pivot means  60  such that first and second support arms  2   a ,  2   b  may pivot relative to first and second sides  20 ,  22 , respectively. A first end  35  of each of first and second support arms  2   a ,  2   b  may be pivotably coupled with a first end  38  of first and second sides  20 ,  22 , respectively, by any pivot means that may enable the retention of first and second support arms  2   a ,  2   b  in a first desired position unless adjusted otherwise. In a preferred embodiment of the invention, each first end  38  of first and second sides  20 ,  22  comprises a socket  5  adapted to receive a knuckle  6  formed at first end  35  of each of first and second support arms  2   a ,  2   b  such that first and second support arms  2   a ,  2   b  may pivot within socket  5  relative to first and second sides  20 ,  22  when knuckle  6  is received in socket  5 . By way of example,  FIG. 7  depicts first pivot means  60  as previously described with respect to first support arm  2   a  in relation to first side  20  but applies equally to second support arm  2   b  in relation to second side  22 . Preferably, when knuckle  6  is received in socket  5 , knuckle  6  frictionally engages socket  5  such that first and second support arms  2   a ,  2   b  may be pivoted only when sufficient force is applied, for example, when manually adjusted by a user to position foldable mirror assembly  50  for hitching a trailer. Absent the application of sufficient force to first and second support arms  2   a ,  2   b , the friction fit and frictional engagement of knuckle  6  in socket  5  otherwise substantially retains first and second support arms  2   a ,  2   b  in the first desired position determined by angle a for optimal viewing, as seen in  FIG. 6 . First pivot means  60  may also include a detent mechanism, such as but not limited to a spring or friction based detent member, to provide at least one detent stop point to assist in substantially retaining first and second support arms  2   a ,  2   b  in angle a in the first desired position unless otherwise adjusted. Otherwise, first and second support arms  2   a ,  2   b  may be generally retained in a substantially static position at angle a by the friction fit of knuckle  6  received in socket  5 . 
         [0025]    First pivot means  60  enables first and second support arms  2   a ,  2   b  to pivot between the first open position and the second closed position relative to base  1 . When in the second closed position, as best seen in  FIG. 5 , both first and second support arms  2   a ,  2   b  may be received in support arm depressions  23  and when in the first open position, as best seen in  FIGS. 1 and 6 , first and second support arms  2   a ,  2   b  may pivot upwards and away from base  1 . For greater clarity, first pivot means  60  enables first and second support arms  2   a ,  2   b  to pivot upwards and away from base  1  from the second closed position where first and second support arms  2   a ,  2   b  are received in support arm depressions  23 , to the first desired position determined by angle a. First pivot means  60  enables first and second support arms  2   a ,  2   b  to be pivoted and substantially retained in the first desired position at angle a when in the first open position to assist in positioning mirror  4  on support  3  in an optimal viewing position, as described in greater detail below. 
         [0026]    When foldable mirror assembly  50  is secured to and used in association with a vehicle having a substantially vertical rear surface, such as a pick-up truck and certain sport utility vehicles, for optimal viewing, first and second support arms  2   a ,  2   b  may be pivoted upwards and away from base  1  and substantially retained frictionally in the first desired position by first pivot means  60  at angle a which may range between 130 degrees and 140 degrees relative to base  1 . In the preferred embodiment, when foldable mirror assembly  50  is secured to and used in association with a vehicle having a substantially vertical rear surface, angle a for optimal viewing is generally 135 degrees relative to base  1  mounted on a substantially vertical surface. To assist in substantially retaining first and second support arms  2   a ,  2   b  in the first desired position at angle a, preferably, each socket  5  comprises a groove  25  and each knuckle  6  comprises a ridge  26  corresponding to groove  25  such that when first and second support arms  2   a ,  2   b  are pivoted to angle a, groove  25  and ridge  26  mate to secure first and second support arms  2   a ,  2   b  at angle a when in the first open position for backing vehicle  7  towards a trailer  8  for connection. Angle a is optimum for vehicles having a substantially vertical rear surface as angle a assists in positioning mirror  4  at the optimal angle for a user to view the hitch area  17  of vehicle  7  and trailer  8  when vehicle  7  backs towards trailer  8 . 
         [0027]    As seen in  FIG. 4 , when foldable mirror assembly  50  is secured to and used in association with a vehicle having a rear surface that is not substantially vertical, such as a conventional car or a hatch back vehicle which has a generally sloped rear surface, to compensate for base  1  being secured to a sloped surface instead of a substantially vertical surface and to achieve optimal viewing, first and second support arms  2   a ,  2   b  are preferably substantially retained frictionally by first pivot means  60  at a smaller angle a compared to angle a when foldable mirror assembly  50  is secured to and used in association with a vehicle having a rear surface that is substantially vertical. Preferably, when foldable mirror assembly  50  is secured to and used in association with a vehicle having a rear surface that is not substantially vertical, angle a for optimal viewing is generally in the range between 30 degrees and 130 degrees relative to base  1 . The frictional engagement of knuckle  6  in socket  5  enables user to adjust and control the position of first and second support arms  2   a ,  2   b  to ensure first and second support arms  2   a ,  2   b  are retained in the first desired position at angle a while vehicle  7  is backed towards a trailer  8  for connection. 
         [0028]    In the second closed position wherein first and second support arms  2   a ,  2   b  and support  3  are received in base  1  in a substantially flat configuration, foldable mirror assembly  50  may be stored or remain attached with vehicle  7  while it is not in use. Advantageously, foldable mirror assembly  50  may be readily available for use at any time with no need for storage, retrieval, and/or remounting. 
         [0029]    As best seen in  FIGS. 1 and 6 , support  3  is preferably generally rectangular and may be pivotably coupled with both first and second support arms  2   a ,  2   b  by way of a second pivot means  70  such that support  3  may pivot relative to both first and second support arms  2   a ,  2   b . Preferably, second pivot means  70  is positioned along the bottom edge  3   a  of support  3 , thus allowing support  3  to pivot parallel to third side  24  of base  1 . In a preferred embodiment of the invention, second pivot means  70  is substantially the same as and operates in a substantially similar manner to first pivot means  60  described above. Support  3  may be pivotably coupled with each of first and second support arms  2   a ,  2   b  at a second end  39  of first and second support arms  2   a ,  2   b  such that support  3  may be retained in a second desired position at angle b relative to the first desired position of first and second support arms  2   a ,  2   b , unless otherwise adjusted. In a preferred embodiment of the invention, a knuckle  12  is formed at each second end  39  of first and second support arms  2   a ,  2   b . Each knuckle  12  is adapted to be received in a socket  11  formed along bottom edge  3   a  of support  3  such that support  3  may pivot relative to first and second support arms  2   a ,  2   b  when each knuckle  12  is received in each socket  11 . In a preferred embodiment of the invention, when knuckle  12  is received in socket  11 , knuckle  12  frictionally engages socket  11  such that support  3  may be pivoted only when sufficient force is applied, for example, when manually adjusted by a user to position mirror  4 . Absent the application of sufficient force to support  3 , the friction fit and frictional engagement of knuckle  12  in socket  11  causes support  3  to be retained in the second desired position determined by angle b, as seen in  FIG. 6 . 
         [0030]    In an embodiment of the invention, first and second support arms  2   a ,  2   b  may further comprise a cross member  13  disposed between first support arm  2   a  and second support arm  2   b . Cross member  13  may be attached with each second end  39  of first and second support arms  2   a ,  2   b  so as to provide greater rigidity and stability to first and second support arms  2   a ,  2   b  when pivoting support  3  relative to first and second support arms  2   a ,  2   b . In such embodiment, knuckle  12  may be formed anywhere along the top edge of cross member  13  as long as each knuckle  12  corresponds to the position of socket  11  formed along bottom edge  3   a  of support  3  so as to enable pivotal, frictional engagement of each knuckle  12  with its corresponding socket  11 . Cross member  13  may be an integrated part of second end  39  of first and second support arms  2   a ,  2   b , thereby incorporating first and second support arms  2   a ,  2   b  and cross member  13  into one component. Preferably, for greater rigidity, second pivot means  70  is a piano style hinge connecting the top edge of cross member  13  with bottom edge  3   a  of support  3 . Cross member  13  may be constructed of injection molded plastic but any lightweight, non-corroding, durable material such as aluminum, stainless steel, fiberglass, plastic, or similar materials, fashioned in a method that creates rigidity and compatibility with corresponding parts. 
         [0031]    Second pivot means  70  frictionally and pivotably attaches support  3  with a second end  39  of each of first and second support arms  2   a ,  2   b  such that support  3  may pivot between the first open position and the second closed position. When in the second closed position, as best seen in  FIG. 5 , support  3  may be received in support depression  16  and when in the first open position, as best seen in  FIGS. 1 and 6 , support  3  may pivot upwards and away from both base  1  and first and second support arms  2   a    2   b . For greater clarity, second pivot means  70  enables support  3  to pivot upwards and away from first and second support arms  2   a ,  2   b  and base  1  when in the second closed position where support  3  is received in depression  16  to the second desired position determined by angle b for optimal viewing when in the first open position. Second pivot means  70  enables support  3  to be pivoted and substantially retained in the second desired position at angle b when in the first open position to assist in positioning mirror  4  in an optimal viewing position. 
         [0032]    For optimal viewing, support  3  may be pivoted upwards and away from first and second support arms  2   a    2   b  and be substantially retained frictionally by second pivot means  70  at angle b which may range between 80 degrees to 100 degrees relative to first and second support arms  2   a    2   b  substantially retained in the first desired position by first pivot means  60 . In the preferred embodiment, angle b for optimal viewing in the first open position is generally 90 degrees relative first and second support arms  2   a    2   b  substantially retained in the first desired position, as best seen in  FIG. 6 . Similar to first pivot means  60 , to assist in substantially retaining support  3  in the second desired position at angle b, preferably, each socket  11  comprises a groove  25  and each knuckle  12  comprises a ridge  26  corresponding to groove  25  such that when support  3  is pivoted to angle b, groove  25  and the ridge  26  mate with each other to substantially secure support  3  and mirror  4  in angle b when in the first open position for backing vehicle  7  towards trailer  8 . 
         [0033]    When first and second support arms  2   a    2   b  are pivoted to angle a in the first desired position, support  3  may also be pivoted to angle b so as to position mirror  4  in the optimal viewing position to provide the operator in the driver position of vehicle  7  with a substantially clear line of sight  10  to mirror  4  via the existing rear view mirror of vehicle  7  or viewing mirror  4  through the rear window of vehicle  7  over obstacles such as a tool box, fuel tank, box cover, rear seating, passengers or cargo in the rear of vehicle  7  as best seen in  FIG. 2 . The optimal viewing position of mirror  4  provides the operator with an unobstructed view of hitch area  17  during the hitching process. The preferred angle b of support  3  relative to first and second support arms  2   a    2   b  in the first desired position in combination with the preferred angle a of first and second support arms  2   a ,  2   b  relative to base  1  as previously described, results in a virtually right angle line of sight  10  for an operator from the driving position in vehicle  7  by reflecting the view of hitch area  17  through mirror  4  to the operator via the existing rear view mirror of vehicle  7  or by viewing mirror  4  through the rear window of vehicle  7 , as best seen in  FIG. 2 . Any necessary adjustments to foldable mirror assembly  50  for optimal viewing may be made by adjusting angle a by adjusting first pivot means  60  as it would be more effective to correct an unfavorable angle caused by foldable mirror assembly  50  not being attached in a substantially vertical position at first pivot means  60 . Preferably, mirror  4  is slightly convex so as to enlarge the view of hitch area  17  to further assist the operator, as seen in  FIG. 6 . 
         [0034]    As seen in  FIG. 3 , support  3  is disposed between support arms  2   a ,  2   b  so as to enable support  3  to be received within depression  16  and support arms  2   a ,  2   b  to be received within depressions  23  in a substantially flat configuration when in the second closed position. Preferably, support  3  and mirror  4  are of suitable size to enable the operator to have a clear view of hitch area  17  from the driver position in vehicle  7 . The size of support  3  and mirror  4  are only limited by the dimensions of base  1  which is preferably between 8 and 24 inches in length along third side  24  and between 8 and 16 inches in height along first and second sides  20 ,  22  such that base  1  may be mounted on the rear of vehicle  7  without affecting the viewing function of foldable mirror assembly  50  or impeding or interfering with the function of vehicle  7 , such as operation of the trunk or visibility through the rear window from the driver&#39;s position. As such, the dimensions of support  3  are preferably between 6 and 24 inches in length along bottom edge  3   a  and top edge  3   b  and between 4 and 8 inches in height along the sides of support  3  such that support  3  may be received in depression  16  when in the second closed position for compact stowage and to protect mirror  4  when foldable mirror assembly  50  is not in use. 
         [0035]    In an embodiment of the invention, support  3  may further comprise a fastening means such as, without intending to be limiting, a catch  15  on top edge  3   b . A corresponding latch  14  may be mounted on base  1  such that latch  14  and catch  15  may be fastened together when support  3  is in the second closed position so as to securely retain support  3  and first and second support arms  2   a ,  2   b  in a substantially flat configuration against and within base  1 . The fastening means enables support  3  and first and second support arms  2   a ,  2   b  to be secured substantially flat against base  1  for convenient stowage when not in use and in the second closed position, as illustrated on  FIG. 5 . Advantageously, the ability to conveniently stow foldable mirror assembly  50  on vehicle  7  in the second closed position when not in use has not been previously disclosed, taught or suggested in the prior art. The folding and retaining of foldable mirror assembly  50  on vehicle  7  when not in use makes it possible for the operator to keep foldable mirror assembly  50  attached to vehicle  7  at all times, thus negating the need for removal or storage. For greater convenience, in an embodiment of the invention, foldable mirror assembly  50  may be mounted to the rear of vehicle  7  such that catch  15  may be coupled with a cable, electric solenoid or similarly operated linkage to enable the operator to release catch  15  from latch  14  by triggering a lever or switch from the drivers position in the vehicle  7 . First and second pivot means  60 ,  70  may further comprise springs that may be compressed in the second closed position such that upon releasing latch  14 , first and second support arms  2   a ,  2   b  and support  3  would automatically displace from the second closed position to the first open position. Advantageously, the operator would not need to exit vehicle  7  to open foldable mirror assembly  50  for use during the hitching process. 
         [0036]    In a second embodiment of the invention, a foldable mirror assembly  150  for hitching trailers may be permanently installed and stored within the rear of a vehicle  107  when not in use, as shown in  FIG. 8 . Foldable mirror assembly  150  may be preferred where the present invention may be incorporated into the manufacture of vehicle  107 . Foldable mirror assembly  150  comprises a first and a second guide rail  140   a ,  140   b  disposed within the rear of vehicle  107 , a first and a second support arm  102   a ,  102   b  slideably mounted on first and second guide rail  140   a ,  140   b , respectively, at a first end, and a mirror  104  mounted on a support  103  wherein support  103  is pivotably coupled with a second end of each of first and second support arms  102   a ,  102   b . First and second support arms  102   a ,  102   b , support  103 , and mirror  104  are similar to first and second support arms  2   a ,  2   b , support  3 , and mirror  4 , respectively, in all respects as described above. 
         [0037]    First and second guide rails  140   a ,  140   b  may be mounted within the rear of vehicle  107  in a position corresponding to the position of first and second sides  20 ,  22  of base  1  in the first embodiment such that first and second guide rails  140   a ,  140   b  will not interfere with the drivability or affect the functioning of vehicle  107 . Preferably, first and second guide rails  140   a ,  140   b  are mounted substantially vertically within the rear of vehicle  107  such that each first end of first and second guide rails  140   a ,  140   b  are substantially flush with the top edge  100  of vehicle  107 . In an embodiment of the invention, first and second guide rails  140   a ,  140   b  are each comprised of a channel track and configured to receive a first and a second carrier  141   a ,  141   b , respectively such that first and second carrier  141   a ,  141   b  may slide along first and second guide rails  140   a ,  140   b , respectively. First and second support arms  102   a ,  102   b  are pivotally coupled with first and second carriers  141   a ,  141   b , respectively such that first and second support arms  102   a ,  102   b  may freely slide along first and second guide rails  140   a ,  140   b  and extend out from top edge  100  of vehicle  107  and retract completely within the rear of vehicle  107 . For greater clarity, first and second support arms  102   a ,  102   b  mounted on first and second carriers  141   a ,  141   b , respectively, slide along first and second guide rails  140   a ,  140   b  so as to enable foldable mirror assembly  150  to extend from the second retracted position within the rear of vehicle  107  to a first extended position outside of the rear of vehicle  107  for optimal viewing. 
         [0038]    Foldable mirror assembly  150  may be retracted and stored within a housing  142  defined by the cavity within the rear of vehicle  107  where first and second guide rails  140   a ,  140   b  are mounted to enable first and second support arms  102   a ,  102   b  to slide vertically on first and second carriers  141   a ,  141   b  between the first extended position and the second retracted position. An aperture  120  defined by top edge  100  enables first and second support arms  102   a ,  102   b  and support  103  to extend out of housing  142  to the first extended position for optimal viewing. When not in use, first and second support arms  102   a ,  102   b  and support  103  may retract into housing  142 . In an embodiment of the invention, a cover  143  pivotably attached to top edge  100  may be pivoted to the closed position to cover aperture  120  when foldable mirror assembly  150  is in the second retracted position and disposed within housing  142  when not in use. When required, cover  143  may be pivoted to the open position to enable foldable mirror assembly  150  to be released from housing  142  and extend through aperture  120  into the first extended position. Alternatively, a cover  144  attached perpendicular to the second end of first and second support arm  102   a ,  102   b , may protect foldable mirror assembly  150  when in the second retracted position. 
         [0039]    Advantageously, foldable mirror assembly  150  may virtually be completely contained within housing  142  when not in use. Foldable mirror assembly  150  may be retrofitted to virtually any existing vehicle such as, but not limited to, a truck or sports utility vehicle tailgate, car trunk, hatchback, or rear of a van, if a hidden installation was desired. A suitable sized slot may be cut into the rear surface of an existing vehicle so as to insert and house foldable mirror assembly  150 . A flange  146  flush to the top of housing  142  facing outward would cover the exposed cut and provide means of flush attachment to top edge  100  on the rear of the vehicle  107 . A detent stop on the top end of first and second guide rails  140   a ,  140   b  that correspond to a matching detent stop on first and second carriers  141   a ,  141   b  assists in retaining first and second carriers  141   a ,  141   b  securely in the first extended position similar to the detent stop described above in relation to first pivot means  60 . A socket  105  may be formed at each first end of carriage blocks  141   a ,  141   b  to receive and frictionally engage a knuckle  106  formed at each first end of support arms  102   a ,  102   b  such that first and second support arms  102   a ,  102   b  may frictionally pivot relative to the first ends of first and second carriers  141   a ,  141   b , similar to the first pivot means described above. Support arms  102   a ,  102   b  may be pivoted to and secured at any desired angle when in the open position to position mirror  104  on support  103  in an optimal viewing position. The preferred optimal viewing position would be an angle of 45 degrees from the mostly vertical position towards the rear. Support  103  operates similarly to support  3  as previously described above to provide the operator with an unobstructed, right angle, line of sight of the rear of the vehicle. Similar to the mechanism described above, foldable mirror assembly  150  may further comprise a latch  114  on cover  143  or cover  144  and a corresponding catch  115  on top edge  100  or flange  146  to secure cover  143  or  144 . Latch  114  may be coupled with a cable, electric solenoid or similarly operated linkage to enable the operator to release latch  114  from catch  115  by triggering a lever or switch from the driver&#39;s position in vehicle  107 . As well, the pivot means between first and second carrier blocks  141   a ,  141   b  and first and second support arms  102   a ,  102   b  and the pivot means between first and second support arms  102   a ,  102   b  and support  103  may further comprise springs compressed when foldable mirror assembly  150  is in the second retracted position such that upon releasing latch  114 , first and second support arms  102   a ,  102   b  and support  103  would automatically displace from the second retracted position to the first extended position. Advantageously, the operator would not need to exit vehicle  107  to open the assembly  150 . 
         [0040]    The present invention may also be used as a device to assist an operator when backing up vehicle  7  for any other purpose or tasks other than trailering, such as, without intending to be limiting, parking vehicle  7  in a small space or backing vehicle  7  into a loading dock. Foldable mirror assembly for hitching trailers  50  may be used by an operator that could benefit from having optimal rear vision immediately behind vehicle  7  from the drivers seat for any vehicular operation. 
         [0041]    The foregoing description is made for purpose of illustration only and is not intended to limit the scope of the invention. From the foregoing, it should be clear that the present invention may be embodied in other forms other than those disclosed above without departing from the spirit or essential characteristics of the invention. The above described embodiments are therefore to be considered in all respects illustrative and not restrictive.
