The stoppers 124, 129 may be comprised of various structures, but will preferably be comprised of peg-like structures extending from the lower end 113 of the plate member 110.
F. Dispensing Assembly.
The dispensing assembly of the present invention includes all of the components which are utilized to squeeze, push down and dispense the objects 86 through the opening 114 of the plate member 110. The dispensing assembly includes a first lever 130 having a first end 131 secured to a first end 141 of a first rail 140 and a second lever 134 having a first end 135 secured to a first end 146 of a second rail 145 as shown in FIGS. 2, 3a and 3b. The second ends 132, 136 of the levers 130, 134 each include a loop 133, 137 which interconnects with the respective lever anchor 125, 126 on the lower end 122 of the knob 120. The levers 130, 134 are utilized to impart turning force from the knob 120 to cause the rails 140, 145 to pivot as described herein.
The present invention includes a first rail 140 and second rail 145, each extending perpendicularly with respect to the levers 130, 134. The rails 140, 145 are adapted to pivot at their second ends 142, 147 which causes the dispensing members 150, 155 to advance toward the center of the opening 114, thus squeezing in and out the objects 86 to be dispensed.
The first rail 140 includes a first end 141 having a first lever peg 138 to which the first end 131 of the first lever 130 will be secured. The second end 142 of the first rail 140 includes a first pivot pin 143 extending therethrough such that the second end 142 of the first rail 140 is pivotally secured to the lower end 113 of the plate member 110 as shown in the figures. The first rail 140 also includes a first dispenser aperture 144 extending therethrough through which the first peg 152 of the first dispensing member 150 will be inserted.
The second rail 145 includes a first end 146 having a second lever peg 139 to which the first end 135 of the second lever 134 will be secured. The second end 147 of the second rail 145 includes a second pivot pin 148 extending therethrough such that the second end 147 of the second rail 145 is pivotally secured to the lower end 113 of the plate member 110 as shown in the figures. The second rail 145 also includes a second dispenser aperture 149 extending therethrough through which the second peg 157 of the second dispensing member 155 will be inserted.
A rail retainer 106 is also provided which extends over the floating ends 141, 146 of the rails 140, 145 as shown in FIGS. 3a and 3b. The rail retainer 106 acts to retain the rails 140, 145 against the plate member 110 and thus not fall loose. The rail retainer 106 should be extended over the rails 140, 145 such that the rails 140, 145 are capable of freely sliding thereunder.
The pivoting action of the rails 140, 145 acts to push in and withdraw one or more dispensing members 150, 155 toward/away from the center of the opening 114 of the plate member 110. While varying numbers of dispensing members 150, 155 may be utilized, a preferred embodiment utilizes a first dispensing member 150 which is slidably secured within the first slot 115 of the plate member 110 and a second dispensing member 155 which is slidably secured within the second slot 116 of the plate member 110.
The first and second dispensing members 150, 155 are each generally comprised of a rectangular member having a tapered front edge 151, 156. The tapering on the front edges 151, 156 aids with pushing the object 86 down to be dispensed while it is being squeezed by the dispensing members 150, 155. The dispensing members 150, 155 each include a peg 152, 157 extending upwardly therefrom which is utilized to secure the respective rails 140, 145 to each dispensing member 150, 155 utilizing the rails' 140, 145 respective dispenser apertures 144, 149. A first dispensing retainer 153 comprised of a bar extending perpendicular to the first dispensing member 150 is positioned over the first dispensing member 150 to secure it within the slot 115 in a manner which allows the dispensing member 150 to slide thereunder. A second dispensing retainer 158 is also provided for the second dispensing member 155 as shown in the figures.
G. Operation of Main Embodiment.
In use, the objects 86 to be dispensed, such as cups or lids, are first stacked within the retention member 100. They are retained within the opening 114 by the dispensing retainers 153, 158, which each slightly abut into the opening 114 as shown in the figures.
Upon turning of the knob 120, the respective levers 130, 134 will impart turning force to pivot the rails 140, 145. The pivoting motion of the rails 140, 145 causes the dispensing members 150, 155 to push inward, thus squeezing the object 86 to be of less diameter than that of the width between the abutted portions of the dispensing retainers 153, 158. The tapered front edges 151, 156 of the dispensing members 150, 155 also aids with pushing the object 86 downward. Since only the lowest of the stack of objects 86 is squeezed and pushed down, the remaining objects 86 are not dispensed until the knob 120 is turned again. Releasing the knob 120 will return it to its rested position absent application of additional force to dispense additional objects 86.
FIG. 7 also illustrates a second version of the main embodiment of the present invention. This version includes everything duplicated side-by-side such that a first retention member 100 may support a stack of a first object 86, such as cups, and the second retention member 100 may support a stack of a second object 86, such as lids.
