Apparatus to dispense two separate products through a coin-operated system

Abstract

A dispenser of feminine pads and tampons activated by a touch sensor. The touch of a person's hand will close an electronic circuit causing a motor to rotate. The motor is attached to a shaft which rotates. The shaft retains a feminine product dispenser. The feminine product dispenser transports a feminine napkin or tampon to a retrieval tray. The improved design enables the sanitary napkin rack and tampon rack to be adjacent to each other, thereby reducing the width requirements for the cabinet housing the racks. The activation by touch screen significantly improves the selection and dispensing of the desired feminine napkin product and tampon product.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION

(24) Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention.

(25) Referring to FIG. 1, there is illustrated a front perspective view of the front surface 110 of the front cabinet door 100 of the present invention coin-operated product dispensing machine. The front cabinet door 100 includes a first or left coin deposit slot 130, a first or left opening 132 for a light to indicate that the vending machine is out of a first product, a right or second coin deposit slot 140 and a second or right opening 142 for a light to indicate that the vending machine is out of the second product. The dispensing machine 10 is programmed to accept either one quarter or two quarters for a purchase of a product. The front cabinet door 100 also includes a retrieval opening 150 leading to a retrieval plate 152 through which a purchased product is retrieved, through which the deposited quarter or quarters is returned if the dispensing machine is out of the product sought to be purchased, or a return of money if an incorrect coin such as a penny, nickle or dime is inserted into either first coin deposit slot 130 or second coin deposit slot 140.

(26) Referring to FIG. 2, there is illustrated a rear perspective view of the back surface 120 of the front cabinet door 100. Also illustrated is the back of the first now on the right coin deposit slot 130 and the back of the second now of the left coin deposit slot 140. Since FIG. 2 is a view from the back, the coin deposit slots are oppositely oriented from the front view. A horizontal separation wall 160 separates the first or right coin deposit slot 130 and the second or left coin deposit slot 140 from the retrieval opening 150. The separation wall 160 is supported against the back surface 120 of front cabinet door 100 by a central mounting bracket 200, a right mounting bracket 210 and a left mounting bracket 220.

(27) A key innovation of the present invention dispensing apparatus are three operation plates. Referring to FIG. 3, there is illustrated an exploded view of the three operation plates and other components which are a major portion of the coin-operated vending machine of the present invention. The parts as numbered in FIG. 3 are described in succeeding paragraphs.

(28) Referring to FIG. 4, there is illustrated a front view of the back plate 300. The rear surface 304 of the back plate 300 faces the back surface 120 of front cabinet door 100. The back plate 300 also includes a front surface 302. The back plate 300 includes a first or right transverse slope 310-R. If an improper coin such as a penny, nickle or dime is inserted into first or right coin deposit slot 130 (as identified from the rear surface 120), the coin is guided along first or right transverse slope 310-R to first or right coin return plate 340-R which causes the improperly inserted coin to fall into the retrieval tray 152 to be retrieved by the person who inserted the wrong coin. If a proper coin such as a quarter is inserted into first or right coin deposit slot 130, the quarter is guided to the first or right coin slide slope 320 to a first or right portion of a central end 338, with the first or right coin slide slope 330 having a first or right upper wall 332 and a first or right lower wall 334 separated by a distance D-1 sized to receive a quarter. The first or right trap door opening 330 is aligned with a first or right coin return plate 340-R. The route the quarter travels will be described after all three operating plates are described.

(29) Similarly, the back plate 300 includes a second or left transverse slope 350-L. If an improper coin such as a penny, nickle or dime is inserted into second or left coin deposit slot 140 ((as identified from the rear surface 120), the coin is guided along second or left transverse slope 350-L to second or left coin return plate 360-L which causes the improperly inserted coin to fall into the retrieval tray 152 to be retrieved by the person who inserted the wrong coin. If a proper coin such as a quarter is inserted into second or left coin deposit slot 140, the quarter is guided to the second or left coin slide slope 370 to a second or left portion of a central end 378, with the second or left coin slide slope 370 having a second or left upper wall 372 and a second or left lower wall 374 separated by a distance D-2 sized to receive a quarter. The second or left trap door opening 380 is aligned with the second or left coin return plate 360-L. The route the quarter travels will be described after all three operating plates are described.

(30) The back plate is retained by the first or right mounting bracket 210, and the second or left mounting bracket 220, with both the bottom surface 342 of the first or right coin return plate 340-R and the bottom surface 362 or second or left coin return plate 360-L. affixed to separation plate 160.

(31) Slope central ends 338 and 378 meet at the effective width-wise center of back plate 300.

(32) In operation, the bottom surface 342 of first or right coin return plate 340-R is affixed to upper surface 162 of separation wall 160 and bottom surface 362 of second or left coin return plate 360-L is also affixed to upper surface 162 of separation wall 160. If an incorrect size coin such as a penny, nickle or dime is inserted into first or right coin slot opening 130, it falls down right transverse return slope 310-R and falls into the top surface 344 of first or right coin return plate 340-R and falls into retrieval tray 152. Similarly, if an incorrect size coin such as a penny, nickle or dime is inserted into second or left coin slot opening 140, it falls down into the top surface 364 of second or left coin return plate 360-L and falls into retrieval opening 150.

(33) Referring to FIG. 5, there is illustrated a front perspective view of the middle plate 400 which includes a back surface 404 facing the front surface 302 of back plate 300.

(53) Referring to FIG. 14, there is illustrated a detailed view of the tampon dispensing cradle 1550 which includes an upper platform 1552, an upper left arm 1554 and an upper right arm 1556 and a tampon pin 1568. Also illustrated is a lower platform 1560, the lower left arm 1562 and the lower right arm 1564 and the lower pin 1566. When the proper coins are inserted as previously described and there is a sufficient quantity of tampon in the rack, the lowermost tampon 1580A is dispensed into the upper platform 1552 of the tampon dispensing cradle 1550 and the tampon motor 1572 rotates the tampon shaft 1574 until the tampon pin 1568 comes in contact with the tampon microswitch 1570 which causes the motor to stop rotating and the lowermost product is now dispensed into the retaining opening 150 for a retaining shelf 152 wherein the retrieved tray 152 where the tampon is retrieved.

(54) Similarly, referring to FIG. 15, for the feminine napkin retaining rack, there is illustrated a detailed view of the feminine napkin dispensing cradle 1650 which includes an upper platform 1652, an upper left arm 1654 and an upper right arm 1656 and a feminine napkin pin 1668. Also illustrated is a lower platform 1660, the lower left arm 1662 and the lower right arm 1664 and the lower pin 1666. When the proper coins are inserted as previously described and there is a sufficient quantity of feminine napkin in the rack, the lowermost feminine napkin 1680A is dispensed into the upper platform 1652 of the feminine napkin dispensing cradle 1650 and the feminine napkin motor 1672 rotates the feminine napkin shaft 1674 until the feminine napkin pin 1668 comes in contact with the feminine napkin microswitch 1670 which causes the motor to stop rotating and the lowermost product is now dispensed into the retaining tray 152 where the feminine napkin is retrieved.

(55) Referring to FIG. 16, there is illustrated an enlarged perspective view of the tampon dispensing cradle, the tampon motor, the tampon shaft, the tampon microswitch and the pin from the tampon cradle, illustrating the cradle in an operative mode to dispense a product such as a tampon. The part numbers are the same as identified in FIG. 14.

(56) Also referring to FIGS. 12 and 13, in the center separate compartment 1100 between the tampon rack 1500 and the feminine rack 1600 is a compartment wall 1120 retaining the motherboard 1000 and the power pack 1200. An electrical connector connected the motherboard 1100 to the power bank 1200.

(57) The operation of the vending machine 100 will now be discussed. As previously stated, if an improper coin such as a penny, nickle or dime is inserted into first or right coin deposit slot 130 (as identified from the rear surface 120), the coin is guided along first or right transverse slope 310-R to the first or right coin return plate 340-R which causes the improperly inserted coin to fall into the retrieval tray 152 to be retrieved by the person who inserted the wrong coin. Similarly, if an improper coin such as a penny, nickle or dime is inserted into second or left coin deposit slot 140 (as identified from the rear surface 120), the coin is guided along second or left transverse slope 350-L to the second or left coin return plate 360-L which causes the improperly inserted coin to fall into the retrieval tray 152 to be retrieved by the person who inserted the wrong coin.

(58) By way of example, the motherboard 1100 is pre-programmed for the vending machine to accept quarters as the proper coin. The motherboard 1100 is pre-programmed for either one quarter or two quarters as the price of a product, which usually is either a tampon or a feminine napkin. If a correct coin, using one quarter as an example, is inserted into coin slot 130 for the purchase of a tampon 1580A and the column 1500 does have at least one tampon available for sale, the quarter 5000 is guided along right slop 830-R of front plate 5000 as illustrated in FIG. 7, is guided between upper wall 832-R and lower wall 834-R until it reaches central end portion 838-R as the quarter rolls down along slope path 836-R, the quarter 5000 hits the bent portion 740-RB of bent trigger shaft 740-R of right trigger switch 700-R and falls into locked coin box 6000. Concurrently, the lowermost tampon 1580A falls onto upper platform 1552 of tampon dispensing cradle 1550 and the motherboard causes right tampon motor 1572 to rotate so that shaft 1574 rotates and tampon dispensing cradle 1550 rotates until upper platform 1552 is upside down, the tampon 1580A falls onto the retrieval tray 1552 and the upper tampon pin 1568 contact tampon microswitch 1570 which causes the right tampon motor 1572 to stop.

(59) Similarly, if a correct coin, using one quarter as an example, is inserted into coin slot 140 for the purchase of a feminine napkin 1680A and the column 1600 does have at least one feminine napkin available for sale, the quarter 5000 is guided to roll along left slid e slope 830-L of front plate 500 as illustrated in FIG. 7, is guided between upper wall 832-L and lower wall 834-L until it reachers central end portion 838-L as the quarter rolls down along slope path 836-L, the quarter 5000 hits the bent portion 740-LB of bent trigger shaft 740-1 of LEFT trigger switch 700-1 and falls into locked coin box 6000. Concurrently, the lowermost feminine napkin 1680A falls onto upper platform 1652 of feminine napkin dispensing cradle 1650 and the motherboard causes left feminine napkin motor 1672 to rotate so that shaft 1674 rotates and the feminine napkin dispensing cradle 1650 rotates until upper platform 1652 is upside down, the feminine napkin 1680A falls onto the retrieval tray 1652 and the upper feminine napkin pin 1668 contacts feminine napkin microswitch 1670 which causes the left feminine napkin motor 156 to stop.

(60) If the supply of a product is exhausted and there is no more product in a rack, an out-of-product warning light advises a potential purchaser not to purchase the product. If the tampon rack 1500 is out of tampons 1580, the tampon weight 1590 is at the bottom of the tampon column and the tampon magnet 1592 is in communication distance with the tampon reed switch 1592.

(61) The motherboard 1100 receives an out-of-product signal from the right reed switch 1530 and causes a warning light, which by way of example is a red blinking light, to shine through opening 132. Similarly, if the feminine napkin rack 1600 is out of feminine napkins 1680, the feminine napkin weight 1690 is at the bottom of the feminine napkin column and the feminine napkin magnet is in communication distance with the feminine napkin reed switch 1630. The motherboard 1100 receives an out-of-product signal from the left reed switch 1630 and causes a warning light, which by way of example, is a red blinking light, to shine through opening 142.

(62) If a purchaser does not see the out-of-product signal or ignores it and deposits the correct coin 500 in the correct slot 130, the following occurs. The bent portion 740-RB of bent trigger shaft 740-R of right trigger switch 700-R extends through right trigger switch slot 836-TSR in right slide slope 830-R of front plate 500 and through trigger switch slot 436-R along right slide slope 436-R of the middle plate 400 and the rolling quarter rolling along either right slide slope.

(63) If middle plate 400 or right slide slope 838-R in front plate 500 hits the bent portion 740-RB of right trigger shaft 740-R, this causes a signal from the motherboard 1100 to activate the right solenoid 670-R causes the retaining pin to move from its restraining contact against right trap door plate 610-R to move into the right solenoid 670-Ra. The under tension spring force of tampon force spring 619-R causes spring loaded right trap door 600-TDR to rotate in a counter-clockwise direction, to rotate from the front surface 502 of third or front plate 500, thereby exposing a right trap door opening 500-TDOR which is aligned with the right trap door opening of middle plate 400, thereby causing the quarter 5000 to fall through either trap door opening and onto the upper surface 344 of return plate 344-R and onto retrieval tray 152.

(64) Similarly, if a purchaser does not see the out-of-product signal or ignores it and deposits the correct coin 5000 in the correct slot 140, the following occurs. The bent portion 740-LB of bent trigger shaft 740-L of left trigger switch 700-L extends through left trigger switch slot 836-TSL in left slide slope 830-L of front plate 500 and through trigger switch slot 436-L along left slide slope 436-L of middle plate 400 and the rolling quarter rolling along either left slide slope.

(65) If middle plate 400 or left slide slope 838-L in front plate 500 hits the bent portion 740-RL of left trigger shaft 740-L, this causes a signal from the motherboard 1100 to activate the left solenoid 670-L causing the retaining pin to move from its restraining condition against left trap door plate 610-L to move back into the left solenoid 670-L. The under tension spring force of feminine napkin force spring 619-L causes spring loaded left trap door 600-TDL to rotate in a clockwise direction, to rotate away from the front surface 502 of third or front plate 500 thereby exposing a left trap door opening 500-TDOL which is aligned with the left trap door opening of middle plate 400, thereby causing the quarter 5000 to fall through either trap door opening and onto the upper surface 364 of return plate 360-L 44 of return plate 344-R and onto retrieval tray 152.
