Abstract:
A convenience-providing truck-windshield cleaning device comprised of a squeegee and a container having interior dimensions only slightly larger than the squeegee for containing a supply of windshield-washing liquid in the lower portions thereof, and a cover for sealing off the interior with the squeegee therewithin, the squeegee having a handle slightly shorter than the depth of the interior of the container to enable same to be completely enclosed within the chamber with the cover of the chamber closed, yet being of sufficient length to enable the truck driver to reach the midsection of the truck&#39;s windshield, for cleaning same while standing beside the truck opposite an end of the windshield.

Description:
BACKGROUND OF THE INVENTION  
         [0001]    This invention relates to truck-driving. More particularly, it relates to a single and inexpensive means for solving or minimizing a serious problem of evening driving by professional, long-range truck drivers, and the like.  
           [0002]    As compared to automobile driving, long-range truck-driving presents an arduous and strenuous task. It is characterized by long hours and distances, lack of adequate sleep, trying road conditions, and especially and frequently, inadequate visibility conditions caused by the windshield of the truck becoming littered, especially during night driving, with flying insects which accumulate rapidly and frequently. When this occurs, the driver properly feels compelled to pull over to the side of the highway to manually clear the windshield of the collected mass of insects, and to clean the same in order to obtain clear vision. At times, the necessity for such stops are frequent, especially in the mid-summer evenings. Because of their frequency, it becomes extremely difficult, and at times impossible for the driver to adhere to his schedule.  
           [0003]    In addition to the above, truck drivers are required to make regular pre-determined stops which consume a substantial portion of their travel time. For all of the above reasons, there is a substantial need for some means for enabling truck drivers to clean the windshields of their trucks quickly and frequently in order to obviate the dangers inherent in the problems described. As a professional truck driver, I am deeply aware of this problem, of the dangers caused thereby and of the need for a simple and inexpensive solution thereof.  
           [0004]    I have found that the practice of pulling our truck-loads into service stations and the like to rid ourselves of the above problems is inadequate because of the inadequacy of space, the lack of an adequate supply of 24-hour service, the problems of traffic, the presence of prior customers and the delays they cause, etc.  
           [0005]    On the other hand, my experience has been that there are frequent locations along any trip at which it is convenient to pull over off the main road, for whatever reason the driver may have. At such locations there is no appreciable loss of time; only that required to remedy the problem at hand is needed. Also, there are no appreciable time delays, because of traffic, in getting back onto the road.  
           [0006]    There is a marked scarcity of longitudinal space along the exterior of almost all trucks. I have compensated for this disadvantage by the manner in which I have designed my container and oriented same on the side surface of the truck.  
           [0007]    I have concluded that we are compelled to solve our above problems ourselves at a self-selected location and time. As a consequence, I have conceived of a device which I have found is simple, inexpensive, and provides an adequate solution.  
         BRIEF SUMMARY OF THE INVENTION  
         [0008]    My invention is designed to be of the utmost convenience, and efficiency for the truck driver in effectively cleaning the truck-windshield in a minimum of time expenditure. It is comprised of a simple rectangular self-contained closed container produced preferably of light non-rusting metal such as aluminum, and having minimum dimensions suitable for receiving, storing, providing ready accessibility, and maintaining a level of windshield cleaning fluid and a squeegee having a handle, all therewithin. It is designed to have one narrow dimension so that it can be mounted on the exterior surface of the truck at a location handy to the driver as he exits from his driver&#39;s seat, while utilizing only a minimum of the longitudinal exterior surface of the truck. The handle of the squeegee is shorter than the depth of the container so the cover seals the squeegee and handle within the compass of the closed container during travel. The vertical depth of the container is about eighteen (18) inches so that the cover can be closed with the squeegee and its handle stored therewithin, and if the cover is unintentionally left open or removed, no appreciable amount of the windshield cleaning fluid will splatter outside the container. The transverse dimension of the squeegee is about four (4) inches or less and the transverse dimension of the container at its narrower dimension is only slightly more than that of the squeegee.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0017]    As shown in FIGS.  1 - 6 , inclusive, the invention includes a chamber  10  made preferably of a non-rusting metal, such as aluminum and having a relatively wide front side panel  11  and backside panel  12 . As shown, the chamber has relatively narrow end panels,  13  and  14  respectively which cooperatively define a rectangular configuration. A bottom wall or floor  15  and a hinged cover member  16  complete the wall structure of the container which is designed to contain window-cleaning liquids.  
         [0018]    The cover member  16  is hingedly mounted upon the upper end the end of panel  14 , as best shown in FIGS. 2 and 4. The hinge  17  is comprised of an elongated mounting panel  18  having upstanding sleeves  19  alternately positioned between cooperating sleeves  20  carried by cover  16  in the conventional manner in which a pin  21  extends through each of the sleeves, as best shown in FIG. 2. A floor member  15  completes the enclosure of the chamber  10 .  
         [0019]    The cover member  16  includes a rubber liner  23  which extends around three (3) sides of the interior of the cover, as best shown in FIG. 6. The rubber liner  23  extends along the inner surface of the depending lip  24  of the cover, as shown.  
         [0020]    The cover  16  also includes a catch  25  which as best shown in FIG. 6, is a split socket designed to receive and retain latch member  26  in extended locking position when its ball element  27  is received therein. Latch member  26  is hingedly mounted on end wall  13  by means of a mounting panel  28  which swingably mounts elastic latch  26  by a pin  24 , which extends through the lower end of latch  26 , as best shown in FIG. 3. Handle member  30  facilitates stretching of latch member  26  sufficiently to enable the driver to stretch the area immediately below ball element  27  sufficiently to enable it to pass through the slot in the split socket of catch  25 , prior to release of tension at the handle  30 . Upon release of tension at the handle, the ball element  27  settles into catch member  25  to effectively retain cover  16  in confining (closed) position, as shown in FIG. 3. Thus, the latch element  26  and catch member  25  together constitute a detent D.  
         [0021]    Floor member  15  has a drain opening  31  through which a drain tube  32  extends. The lower end of this drain tube is internally threaded to receive and retain a threaded plug  33 , as best shown in FIG. 5.  
         [0022]    The chamber  10  is shown in FIG. 1, mounted upon the side rail of a truck T. As shown therein the chamber is mounted thereon by means of a pair of mounting flanges  34  and  35  which are carried by the chamber  10  at the upper end of the opposite side edges of rear panel  12 . Each of the mounting flanges have openings such as  36  and  37  by means of which bolts (not shown) are accommodated to secure the flanges to the truck side rail, with the back wall  12  parallel to the longitudinal axis of the truck and flush against the side rail  50 .  
         [0023]    [0023]FIG. 7 discloses a second embodiment of my invention which varies from the above described first embodiment shown in FIG. 1- 6 . inclusive in that its mounting flanges  38  and  39  (not shown), which are identical in construction to the mounting flanges  34  and  35 , differ in that they are secured to the upper end of the chamber  40  at opposite sides of narrow panel  41  and extend outwardly therefrom. If desired the flanges  38  and  39  may be a part of the narrow panel  41  when the latter is formed. As shown, each of the flanges  38  and  39  (not shown), are means by which the flanges and chamber may be mounted upon the side rail  50  of truck T in the same manner as that described above with respect to FIGS.  1 - 6 .  
         [0024]    The chamber  40  is similar to chamber  10  but differs therefrom in that its mounting flanges  38  and  39  extend outwardly from and parallel to one of its narrow wall panels ( 41 ) instead of from one of the relatively wide side panels, and consequently the narrow panels  41  and  42  extend parallel to the longitudinal axis and side rail  50  of the truck, instead of normal thereto, as in FIG. 1- 6 , inclusive.  
         [0025]    In addition to the above the detent, which is identical in construction to detent D, is carried by the wide side panel  43  and the cover member  44 . Cover member  44  is constructed similarly to cover member  16 , except that its catch member is carried at the wider side  45  of the cover  44  and its similar hinged connection  46  to the side wall  47  is similar in construction to hinge  17 . As a consequence of the above, the horizontal length of the entire assembly shown in FIG. 7, when mounted on the truck&#39;s side rail  50 , extends normal to the side rail, with its narrow panels  41  and  42  parallel to the longitudinal axis of truck T. Thus, a minimum of space along the side rail  50  is utilized and the balance of the valuable space is available for mounting other needed equipment, such as tool boxes, etc.  
         [0026]    [0026]FIG. 8 shows a third embodiment of my invention which varies only from that shown in FIGS.  1 - 6 , inclusive, in that the two mounting flanges extend vertically throughout the vertical length of the rear panel. Where the corresponding parts are identical, they have been identified in FIGS. 7 and 8 by the same means of identification as shown in FIGS.  1 - 6 . The corresponding mounting plates which are mounted on back wall  12  and constitute the only difference, have been given numerals  48  and  49 . It is believed that the use of the different mounting plates  48  and  49  may simplify manufacturing procedures.  
         [0027]    The depth of each of the above chambers is such as to provide that the cover member may be held in closed position by the associated detent, with the squeegee handle H disposed entirely therewithin. Their depth is sufficient to preclude the windshield-washing fluid, covering the squeegee S, from splattering out of the chamber while going over rough roads, in the event that the chamber is inadvertently left uncovered. The depth of the chambers is approximately 18 inches. The most narrow dimension of the squeegee is about four (4) inches thick and the most narrow horizontal dimension of the chamber is slightly more that four (4) inches. The widest interior horizontal dimension of the chamber is slightly more than the width of the squeegee.  
         [0028]    My above truck-windshield cleaning device provides a number of advantages over previously know windshield cleaners. Most importantly, substantial convenience at a minimum expense is provided. The cover is effective and desirable in precluding freezing of the cleaning fluid and in preventing the entrance of contaminants such as dirt, insects, etc. into the windshield-cleaning fluid. The availability of the squeegee S at all times is important to the truck driver because of its convenience, which is a time-saving consideration. The selection of a handle length which enables the driver to reach the windshield mid-center, yet provides its instant availability, while providing protection against insects, dirt and other contaminants entering the cleaning fluid, has proved to be a desirable attribute which is greatly appreciated by professional drivers. In addition, I have found that these chambers preclude loss of fluid when traveling over rough roads, in the event the driver inadvertently fails to close the cover of the chamber.  
         [0029]    It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of the invention which comprises the matter shown and described herein and set forth in the appended claims.
