Abstract
A vending machine having a vandal panel and main door that can be easily removed through upper and lower hinge assemblies without use of conventional fasteners and tools is provided. As a result, the depth of the vending machine is reduced.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention is directed to a vending machine having a main door that is easily removable from the vending machine cabinet. More specifically, the invention is directed to a vending machine in which the main door can be removed without tools in order to minimize cabinet depth.




2. Related Art




In a conventional vending machine, the vandal panel is permanently attached to, and protrudes past the front of the cabinet. The lower hinge of the main door and the door lifter bracket rest on a base plate, which also extends past the front of the cabinet. Both of these features effectively increase cabinet depth, making it difficult, if not impossible, to locate the vending machine in a narrow passageway. Also, in a conventional vending machine, the upper hinge of the main door is held in place by five fasteners, and the inner door is mounted to the main door by two self-tapping screws. Removal of the main door from the cabinet requires removal of all five main door fasteners; and removal of the inner door from the main door requires removal of the self-tapping screws. Conversely, assembly of the main door to the cabinet and the inner door to the main door require re-installation of the fasteners and the self-tapping screws, respectively. Neither the fasteners nor the self-tapping screws can be removed or re-installed without the use of tools.




Although there are many examples of mechanisms designed to facilitate the installation and removal of doors and the like from cabinets, refrigerators, other enclosures, and support surfaces (see, for example, U.S. Pat. No. 5,806,144 to Fries; U.S. Pat. No. 5,265,954 to Keil; U.S. Pat. No. 5,193,308 to Davidian; U.S. Pat. No. 4,620,392 to Kerpers et al.; U.S. Pat. No. 4,099,293 to Pittasch; U.S. Pat. No. 3,478,383 to Brooks; U.S. Pat. No. 3,270,462 to Obadal et al.; U.S. Pat. No. 2,385,169 to Stone; U.S. Pat. No. 1,564,668 to Hageman; U.S. Pat. No. 1,012,606 to Davis; and Pat. No. 42,764 to Harrington), the prior art does not provide any such mechanism adapted to permit the installation and removal of a main door of a vending machine quickly and without tools. It is to the solution of these, and other problems, to which the present invention is directed.




SUMMARY OF THE INVENTION




It is therefore a primary object of the present invention to provide a vending machine in which the vandal panel and the main door can be easily removed, particularly without the need to remove fasteners or use tools to effect removal of the vandal panel and the main door.




It is another object of the present invention to provide a vending machine in which the depth of the main door lower hinge is reduced.




It is still another object of the present invention to provide a vending machine in which the inner door can easily be removed from the main door.




These and other objects of the invention are achieved through provision of a vending machine having a selectively removable main door that is assembled to the vending machine cabinet by upper and lower hinge assemblies that omit conventional fasteners that require tools for their installation and removal.




The upper hinge assembly includes a hinge plate that is selectively engageable with the main door and an upper hinge latch mechanism that is installed in the interior of the cabinet and that selectively mounts the hinge plate to the cabinet. The upper hinge latch mechanism includes a spring-biased plunger that is normally biased to engage the hinge plate. The lower hinge assembly includes a hinge base that is also selectively engageable with the main door and a lower hinge latch mechanism that is installed in the interior of the cabinet and that selectively retains the hinge base in the cabinet. The lower hinge latch mechanism includes a spring-biased pin that is normally biased to engage the hinge plate.




In one aspect of the invention, an inner door is provided over the inner face of the main door. An inner door hinge assembly hinges the inner door to the hinged side of the interior face of the main door along one side thereof and permits selective removal of the inner door from the main door without the use of tools or the removal of fasteners.




In another aspect of the invention, a vandal panel is positioned to cover the facing edges of the hinged sides of the main door and the cabinet when the main door is in the closed position. The vandal panel has upper and lower ends engaging the hinge plate and the lower hinge assembly, respectively, and is removable therefrom without the use of tools or the removal of fasteners.




In still another aspect of the invention, a door lifter mechanism is provided for supporting the weight of the main door while the main door is in the closed position, and for compensating for any sagging of the main door that may occur. The door lifter mechanism comprises a door lifter extending outwardly from the inner face of the main door and a door lifter bracket positioned in the cabinet to receive the door lifter bracket when the main door is in the closed position.




Other objects, features and advantages of the present invention will be apparent to those skilled in the art upon a reading of this specification including the accompanying drawings.

152


is attached to the left cover panel by fasteners


170


such as four self-tapping screws. A horizontally-oriented dowel


172


is inserted through the latch pin


162


and provides a lower bearing surface for the coil spring


160


to normally bias the latch pin


162


in a downward position. Downward travel of the latch pin


162


is limited by an e-clip


174


inserted into a circumferential groove


176


in the latch pin


162


below the dowel


172


.




Should the vending machine


10


be overturned, the downward bias provided by the coil spring


160


will hold the latch pin


162


in position. However, the dowel


172


can be used to lift up the latch pin


162


to release the hinge base


132


from the guide channel


136


. Once lifted, the dowel


172


can also be rotated so that one end engages a notch


180


provided in the back of the latch housing


152


, to retain the latch pin


162


in the upward position in engagement with the aperture


166


in the hinge base


132


.




As in a conventional vending machine, the interior face of the main door


60


of the vending machine


10


in accordance with the invention is provided with an inner door


182


. However, to provide ease of handling, and to eliminate some of the bulk resulting from having the inner door


182


attached to the main door


60


during removal of the main door


60


, the inner door


182


of the vending machine


10


in accordance with the present invention is selectively removable. To this end, the top of the inner door


182


is hinged to the main door


60


by a conventional fixed pin


184


, and the bottom of the inner door


182


is hinged to the main door


60


by a removable hinge pin assembly


190


.




The hinge pin assembly


190


comprises a hinge bracket


192


mounted to the inner face of the main door


60

194


positioned in the housing, and a vertical hinge pin


196


inserted in the coil spring


194


and having its upper and lower ends extending through aligned apertures


200


in the top and bottom of the hinge bracket


192


and in the bottom of the inner door


182


. The hinge bracket


192


is attached to the main door


60


by fasteners such as two self-tapping screws


202


. A bushing


204


is inserted into an aperture


206


in the inner door


182


to act as a guide for the hinge pin


196


. The hinge pin


196


is provided with an operating handle


210


that functions as an upper bearing surface for the coil spring


194


to normally bias the hinge pin


196


in an upward position. The operating handle


210


can be used to depress the hinge pin


196


to release it from the inner door


182


. Once depressed, the operating handle


210


can also be rotated so that it engages a notch


212


provided in the side of the hinge bracket


192


, to retain the hinge pin


196


in the depressed position.




The vending machine


10


is provided with a door lifter assembly


220


to support the weight of the main door


60


while closed, and to compensate for any door sag that may occur. The door lifter assembly


220


comprises a door lifter


222


and a door lifter bracket


224


. The door lifter


222


is mounted on the lower inside corner of the main door


60

and the rear hinge pin


280


. The bottom hinge plate


260


drops down into position when the clearance hole


270




a


in the rear slot


270


of the bottom hinge plate


260


engages the top head portion


280




a


of the rear hinge pin


280


. The notch


266


in front wall


260




b


of the bottom hinge plate


260


provides a finger hold for removing the bottom hinge plate


260


when it is fully inserted into the notch


274


of the right panel


22


of the cabinet


12


.




The rear hinge pin


280


supports the weight of the main door


60


and acts as a guide for inserting the bottom hinge plate


260


into the notch


274


. The top head portion


280




a


of the rear hinge pin


280


limits movement of the bottom hinge plate


260


when engaged with the clearance hole


270




a


of rear slot


270


of the bottom hinge plate


260


. The rear hinge pin


280


can be attached to the bottom wall


12




e


of the cabinet


12


by welding, by providing a hole in the base plate


130


(not shown) and threads on hinge pin


280


configured to engage a nut


282


underneath the bottom wall


12




e


when the hinge pin


280


is inserted through the hole in the bottom wall


12




e


, or by any other suitable means.




When the bottom hinge plate


260


is positioned in the fully retracted position (FIG.


9


), its front aperture


268




a


is in registration with the longitudinal slot


296


in the upper wall


290




a


of the hinge guide


290


. Conversely, when the bottom hinge plate


260


is in the extended position (FIG.


10


), its central aperture


268




b


is in registration with the longitudinal slot


296


. In both cases, the lip


312


of the latch


310


will pass through the aligned slots and provide a positive engagement for the bottom hinge plate


260


to prevent it from “walking.”




The latch


310


is secured in place by a latch retainer


330


positioned against the side surface


22




b


of the right panel


22


of the cabinet


12


. The latch retainer


330


includes top and bottom ends


330




a


and


330




b


, an opening


332


formed in the top end


330




a


, and a notch


334


formed in the bottom end


330




b


and configured to receive the latch


310


. The latch retainer


330


is placed against the side surface


22




b


so that the notch


334


engages the latch


310


. A fastener


336


, such as a tapping screw, is inserted through the opening


326


located above the aperture


320


in the side surface


22




b.






The bottom edge


320




a


of the aperture


320


acts as a hinge point, allowing the latch


310


to pivot upwardly and downwardly against the bottom edge


320




a


. If the vending machine


10


were overturned and the latch


310


became disengaged, the rear hinge pin


280


would prevent the bottom hinge plate


260


from being pulled out of the vending machine


10


, and thus would prevent access to the inside of the vending machine


10


.

102


is used to pull down the plunger


90


, thus disengaging the hinge plate


70


from the latch mechanism


72


at the top of the cabinet


12


. In the lower hinge assembly


64


, the dowel


172


is used to pull up the latch pin
