Abstract
Description
- The present invention relates to a coin box storage structure used for a vending machine or pay telephone.
- A coin box storage structure of this type generally has a box-like safe main body having an opening in its upper surface, a lid arranged to close or open the opening of the safe main body and having a storage port in its upper surface to store a coin, and a safe chamber having an opening for loading the safe main body therein and a drop port in its upper surface to drop a coin so as to correspond to the storage port or window. The lid has a shutter plate for opening or closing the storage port and a lock mechanism for locking the shutter plate. When the safe main body is kept loaded in the safe chamber, the shutter plate opens the storage port to allow storage of a coin. When the safe main body is removed from the safe chamber, the lock mechanism locks the shutter plate so as to close the storage port of the shutter plate, thereby preventing illegal removal of a coin from the storage port. When a lock is released to open the lid from the safe main body, the lock mechanism is automatically released. The shutter plate is swung in reloading of the safe main body in the safe chamber to set the storage port in an openable state, i.e., in the preset state.
- A coin box having this structure is disclosed in, e.g., Japanese Utility Model Publication No. 53-14233. As shown in Fig. 13, the disclosed coin box structure includes a
shutter plate 22, anactuating plate 25, apress plate 29, alock plate 36, anauxiliary lock lever 39, and an L-shaped lever 32 on alid base 20. Theshutter plate 22 has a window 22a and can pivot about ashaft 23 to open or close acoin storage port 21. The actuatingplate 25 can pivot about ashaft 24 to actuate theshutter plate 22. Thepress plate 29 is fixed on the apparatus main body to press theshutter plate 22 upon insertion of the coin box into the apparatus main body. Thelock plate 36 can pivot about ashaft 35 to lock theshutter plate 22 while the window 22a overlaps thecoin storage port 21. Theauxiliary lock lever 39 can pivot about ashaft 38 to actuate thelock plate 36. The L-shaped lever 32 can pivot about ashaft 31 extending on theactuating plate 25 and cooperates with thepress plate 29 to return theshutter plate 22 and theactuating plate 25 to the reset state shown in Fig. 13 when the coin box is removed. When thelock plate 36 for locking theshutter plate 22 opens thelid base 20, a cam portion 39' of theauxiliary lock lever 39 is engaged with a projection formed inside the main body of the coin box to cause theauxiliary lock lever 39 to actuate thelock plate 36. Therefore, theshutter plate 22 is pivoted over a fixed fulcrum clockwise from the state in Fig. 13 and is set in the preset state. - In the conventional coin box storage structure described above, when the
base 20 is open to set theshutter plate 22 in the preset state, the projection engaged with the cam portion 39' is fixed on the main body of the coin box. For this reason, an abrupt large force acts on both theauxiliary lock lever 39 of the cam portion 39' and the projection during opening of thebase 20, and damage and failures tend to occur. - It is an object of the present invention to provide a coin box storage structure which is almost free from damage and failures in a preset operation of a shutter plate.
- It is another object of the present invention to provide a coin box storage structure capable of performing a smooth preset operation of the shutter plate.
- In order to achieve the above objects of the present invention, there is provided a coin box storage structure, comprising a coin box having a coin box main body having an opening in an upper surface thereof and a lid pivotal about one edge thereof as a fulcrum to be opened with respect to the coin box main body and having a coin storage port in an upper surface thereof, a safe chamber, having a coin drop port corresponding to the coin storage port, for storing the coin box, a shutter plate, swingably disposed in the lid, having a projection, and applied with a biasing force in a direction to close the coin storage port, for opening the coin storage port against the biasing force when the coin box is stored in the safe chamber, a lock lever having a ratchet portion engaged with the projection of the shutter plate to hold a state of continuously closing the coin storage port when the coin box is removed from the safe chamber, and pressed and pivoted by the shutter plate when the coin box is stored in the safe chamber, a tumbler mechanism for, when the lock lever is pivoted by not less than a predetermined angle during opening of the lid, reversing the lock lever to disengage the ratchet portion from the projection of the shutter plate to set the shutter plate in a preset state, and for, when the lock lever is pivoted by not less than the predetermined angle during storage of the coin box into the safe chamber, reversing the lock lever to set the ratchet portion and the projection of the shutter plate in an engagement standby state, and a dampening member for inhibiting to apply a pivot force to the lock lever in an initial period of pivotal movement of the lid and pivoting the lock lever in pivotal movement of the lid by an angle exceeding the predetermined angle.

shutter lock cover 127 having awindow 127a is mounted below the notchedwindow 116c of theshutter cover 116. Alock lever 130, alock cam 140, and abracket 145, all of which are illustrated in detail in Fig. 6, are disposed in theshutter lock cover 127. Thelock lever 130 has aratchet portion 130a at its one end, a pressedportion 130b at its other end, and aprojection 130c on the lower surface between the pressedportion 130b and the central portion thereof. Acylindrical portion 131 extends from the lower center surface. Apreset lever portion 132 is integrally formed with the lower end face of thecylindrical portion 131. - The
lock lever 130 is pivotally supported such that itscylindrical portion 131 is fitted on ashaft 133 extending on thepartition plate 115 and inserted through thegroove 125a of theshutter plate 120. Thelock lever 130 is biased by acoil spring 135 hooked between apin 134 extending on thepartition plate 115 and theprojection 130c. Thepin 134 serves as a fixed fulcrum of thespring 135, and theprojection 130c serves as a movable fulcrum. Theprojection 130c serving as the movable fulcrum constitutes a tumbler mechanism selectively moved clockwise or counterclockwise with respect to, as a boundary, a line K connecting thepin 134 and theshaft 133. - The
lock cam 140 has a pair of upper and lower regulation end faces 141a and 141b obtained by notching an edge portion at a predetermined angle. A pair ofcam surfaces preset lever portion 132 are formed in thelock cam 140 toward its distal end portion. Thelock cam 140 is swingably supported by the bracket 145 (to be described detail) about apin 144. Thebracket 145 has anupright portion 145a fixed to the inner surface of themain body 102 and serving as a stopper portion engaged with thecam surfaces lock cam 140 is swingable with a play within the range in which thecam surfaces upright portion 145a. - The present invention has the above structure, and the operation of this structure will be described below. To recover a coin or the like, when the
coin box 101 is removed from thesafe chamber 110, theshutter plate 120 is pivoted counterclockwise by a biasing force of thespring 123 and abuts against thestopper pin 124. In this state, thecoin storage ports shutter pin 124, and theratchet portion 130a of thelock lever 130 is engaged with the engagingprojection 120c of theshutter plate 116. Theshutter plate 120 is locked in this state. Thecoin box 101 removed from thesafe chamber 110 is prevented from illegal removal of a coin through thecoin storage ports - At this time, the engaging portion between the
ratchet portion 130a and the engagingprojection 120c is covered with the shieldingportion 125 of theshutter plate 120 which faces the notchedwindow 116c of theshutter cover 116. Even if theratchet portion 130a is forced to be disengaged from the engagingprojection 120c by a thin member such as a steel wire through the gap between thecoin storage port 103d of thelid 103 and theshutter plate 120, insertion of the thin member is interfered with the shieldingportion 125. Therefore, illegal removal of the coin from thecoin storage ports - In this embodiment, the engaging portion between the
ratchet portion 130a and the engagingprojection 120c is mainly covered with the shieldingportion 125. However, to more perfectly prevent illegal removal of coins, the notchedwindow 116c may be entirely covered. - A preset operation of the
shutter plate 120 will be described below. To recover coins, as shown in Fig. 7A, a locking key (not shown) is unlocked and removed from thelock hole 106a of the fixinglock piece 106, and themetal lock piece 107 is manually held to open thelid 103. Thelock lever 130 pivotally supported by theshaft 133 extending on thepartition plate 115 is moved upward accordingly. At this time, in a state wherein thelid 103 is closed, the lowerregulation end face 141a of thelock cam 140 is engaged with theupright portion 145a of thebracket 145 by the weight of thelock cam 140, as shown in Fig. 5. When thelid 103 is lifted, thepreset level portion 132 abuts against thelower cam surface 142a of thelock cam 140 to pivot thelock cam 140 about thepin 144 counterclockwise by a predetermined angle, as shown in Fig. 7B. When the upperregulation end face 141b is engaged with theupright portion 145a, the pivotal movement of thelock cam 140 is stopped. - As described above, the play is provided to the
lock cam 140 such that thecam 140 is pivotal within the predetermined angle. An external force abruptly acting on thepreset lever portion 132 at the start of opening of thelid 103 is dampened and absorbed to prevent damage to thepreset lever portion 132 and thelock cam 140. - When the
lid 103 is continuously opened, thelock lever 130 is pivoted in a direction indicated by an arrow A in Fig. 7B against thecoil spring 135, i.e., clockwise about theshaft 133 while anedge 132a of thepreset lever portion 132 is being slid along thelower cam surface 142a of thelock cam 140 because the pivotal movement of thelock cam 140 is regulated. - When the
lid 103 is being opened, and theedge 132a of thepreset lever portion 132 reaches the distal end as a boundary between the upper andlower cam surfaces lock cam 140, as shown in Figs. 8A and 8B, theprojection 130c serving as the movable fulcrum of thelock lever 130 is located on the boundary line K. When thelid 103 is continuously opened from this state, themovable fulcrum 130c is reversed over the boundary line K. Thelock lever 130 is pivoted counterclockwise about theshaft 133. As shown in Fig. 9, theratchet portion 130a is disengaged from the engagingprojection 120c, and the regulation of pivotal movement of theshutter plate 120 is released. Theshutter plate 120 is thus set in the preset state. At the same time, the pressedportion 130b of thelock lever 130 abuts against the stepped portion of thepress portion 120b of theshutter plate 120. That is, the preset state is automatically set during opening of thelid 103 to recover the coins. At this time, thelock lever 130 is disengaged from thepreset lever 132 and returns to the initial state by its weight such that the lower engaging end face 141 abuts against theupright portion 145a of thebracket 145. - After recovery of the coins, when the
lid 103 is closed again, thepreset lever portion 132 is held in a state of disengagement from thelock cam 140, and theshutter plate 120 is held in the preset state, accordingly, as shown in Fig. 9. - Figs. 10A and 10B show a special state, i.e., a state in which the preset state is released in an open state of the
lid 103. For example, even if a coin collector opens thelid 103 and operates thelock lever 130 from the space at theshutter lock cover 127 or the like to release the preset state of theshutter plate 120, the preset state can be set again. This will be described below. - More specifically, upon release of the preset state, the
lock lever 130 is reversed, and theedge 132a of thepreset lever portion 132 abuts against theupper cam surface 142a of thelock cam 140 returning to the initial position. In this state, when thelid 103 is closed, the lowerregulation end face 141a of thelock cam 140 abuts against theupright portion 145a to prevent pivotal movement of thelock cam 140. Thepreset lever portion 132 is pivoted in the direction indicated by the arrow A, and thelock lever 130 is also pivoted counterclockwise about theshaft 133. Theprojection 130c serving as the movable fulcrum is moved over the boundary line K in the same manner as described above. Theshutter plate 120 is set in the preset state again, as shown in Fig. 9. - In setting the
shutter plate 120 in the preset state during opening/closing thelid 103, since the ridge is formed by thecam surfaces lock cam 140 to which oneedge 132 of thepreset lever portion 132 abuts, thelock lever 130 can be smoothly pivoted. - An operation for storing the
coin box 101 in thesafe chamber 110 will be described below. When the locking key is locked in thelock hole 106a of the fixinglock piece 106, and thecoin box 101 is stored in thesafe chamber 110, thepress plate 112 of thesafe chamber 110 is inserted into thelid 103 through theslit 103c of thelid 103. Thepress groove 112a of thepress plate 112 is engaged with theshutter pin 120e of theshutter plate 120. Theshutter plate 120 set in the preset state is pivoted clockwise about thepin 121 against thespring 123. Upon this pivotal movement, the pressedportion 130b of thelock lever 130 which is in contact with thepress portion 120b of theshutter plate 120 is also pressed to pivot thelock lever 130 clockwise about theshaft 133. Theprojection 130c serving as the movable fulcrum reaches the boundary line K. At this time, thepreset lever portion 132 is located obliquely downward from thelower cam surface 142a of thelock cam 140, as shown in Fig. 11B. - When the
coin box 101 is further pushed inside thesafe chamber 110, theprojection 130c is moved over the boundary line K, and thelock lever 130 is reversed. Theratchet portion 130a abuts against thepress portion 120b of theshutter plate 120 and can be engaged with the engagingportion 120c. As shown in Fig. 12, when thecoin box 101 is completely stored in thesafe chamber 110, theshutter plate 120 is moved away from thecoin storage ports shutter plate 120 is released and held in the current state by thepress plate 112. - When the
coin box 101 is removed from thesafe chamber 110 to recover the coins, thepress plate 112 is removed from thelid 103, and theshutter plate 120 is pivoted counterclockwise by the biasing force of thespring 123 to close thecoin storage ports ratchet portion 130a of thelock lever 130 causes thepress portion 120b to slide and engages with the engagingprojection 120c, thereby obtaining the state shown in Fig. 3. The engagingprojection 120d serves as a supplementary engaging projection arranged if theratchet portion 130a cannot engage with the engagingprojection 120c, thereby allowing thelock lever 130 to perfectly lock theshutter plate 120. - In this embodiment, the play is provided to pivot the
lock cam 140 within the range of the predetermined angle. However, the present invention is not limited to this. A similar impact absorption effect can be obtained when thelock cam 140 is biased by an elastic member such as a spring in one direction and pivotal movement of thelock cam 140 is regulated by this elastic member during opening/closing thelid 103. - The same effect as described above can be obtained when an impact absorption member as of rubber may be adhered to the portion around the
lock cam 140 and the upright portion 145a. of thebracket 145. - As has been described above, according to the present invention, the play is provided by the dampening member such as a lock cam and the like between the opening/closing operation of the lid and the pivotal movement of the lock lever, and an impact generated during opening/closing the lid to obtain the preset state of the shutter plate is absorbed by the play. Therefore, the preset state can be smoothly obtained, and damage and failures can be prevented.
