Definitions

  • a parking meter includes a timing unit, a coin receiver which can receive coins: of different diameters. and a first and a second norrrially blocked lever which are biased for movement in mutually opposite directions about a joint axis of rotation into detecting engagement with a plurality of angularly spaced points on the circumference of the coin in the receiver, so as to detect the diameter of such coin.
  • a manually operable arrangement serves to unblock the levers for their movement, and for subsequent joint angular displacement through a distance which is dependent upon the detected coin diameter.
  • a control arrangement on one of the levers sets the timing unit to an interval whose length is a function of the aforementioned distance.
  • the present invention relates generally to a manually activated apparatus for timing of intervals of different length in dependence upon a characteristic of an inserted coin.
  • the invention relates to a parking meter which is manually operated.
  • the present invention will hereafter be described with reference to manually operated parking meters, that is parking meters on which the purchased time will be indicated not in automatic response to the insertion of a coin, but only if a handle or the like is operated by a user after inserting the coin.
  • the present invention is usable in other contexts also, for example in connection with coin-operated childrens rides, coin-operated games, and the like.
  • Parking meters are essentially of two basic types, namely the type in which a coin is inserted and the parking meter becomes activated and automatically set to a certain time interval, as soon as the coin has been inserted, found acceptable and identified as to its value upon which the length of purchased time will depend. The user need do nothing more than insert the coin.
  • the other basic type of parking meter requires that the coin be inserted and that thereafter a lever, knob, handle or the like be turned or otherwise operated by the user.
  • the time which is purchased again depends upon the identified value of the coin, but the timer of the parking meter will not begin to operate, and timing indication will appear on the parking meter, until the user has operated the parking meter handle.
  • the present invention is concerned with this second type of parking meter.
  • parking meters of this type are desired to be operable not only for a single time interval, e.g. for an hour, but for different time intervals e.g. a quarter hour, a half hour and an hour, which depend upon the value of the inserted coin.
  • a nickel may for instance purchase a minute parking time interval
  • the insertion of a dime may purchase a half hour parking time interval
  • the insertion of a quarter may purchase a 1 hour parking time interval, to take one example.
  • the parking meter could be of the type which accepts only dimes and in this case the insertion of a first dime might purchase a 15 minute parking time interval, the insertion of an addition dime might purchase an addition 15 minute parking time interval, the insertion of a third dime might purchase still another 15 minute parking time interval, and so on.
  • Another type of parking meter utilizes different coins for different time intervals, e.g. the aforementioned nickels, dimes and quarters. In all instances, however, the nominal value of an inserted coin is determined by measuring the dimensions of the coin, since these are most readily ascertainable in mechanical parking meters.
  • German Pat. No. 1,815,601 can be operated with different-value coins each of which will purchase a different parking-time interval.
  • the device can be changed to accommodate it to different-value coins and to different purchased time intervals, by replacing an entire series of internal components with others, independence upon the desired coin value change or time interval change that is to be effected. This requires that for each different type of coin, or for each different time interval that is to be paid-for by a particular coin, different components must be insertable into this prior-art apparatus.
  • this prior-art construction utilizes, in common with other prior-art constructions of this type, the concept of having individual coin inserting slots for three or more coins of different value.
  • this requires that the user consider the special operating instructions which must go along with a parking meter of this type. In other words, the user must be certain to select the proper coin for the proper coin slot, in order to obtain a desired parking time interval.
  • the higherdenomination coins are made of a more valuable metal than the lower-denomination coins, and are consequently of smaller dimensions.
  • such a coin can be readily inserted into a larger slot intended for a lower-denomination coin.
  • the inserted higherdenomination coin will not trigger the operation of the parking meter, when it has been inserted into the wrong slot, and in consequence the user will have lost the value of this coin without receiving a corresponding parking time interval in return. Since parking meters as a rule do not have a coin-return arrangement, the value of the inserted coin will be lost to the user.
  • a further prior-art parking meter is disclosed in German Pat. No. 1,474,749.
  • This device also, has three slots of different dimensions which can each accept a coin of different value. Interiorly, the device is provided with three diameter-testing arrangements, one each for testing a coin inserted through a particular one of the three slots. The testing of the coin diameters is carried out by cooperation of a plurality of arms or pawls which are formed with recesses of different depth in correspondence with the different coin diameters to be tested, located opposite to corresponding projections adjacent the respective coin inlet slot. The arrangement for testing the coin diameter is quite complicated.
  • an object of the present invention to provide an improved manually operated apparatus for timing of intervals of different length which are selected in dependence upon a characteristic of an inserted coin, especially a parking meter, which avoids the aforementioned disadvantages
  • An additional object of the invention is to provide such an apparatus which is of very simple construction, compared to the prior art.
  • Another object of the invention is to provide an improved parking meter of the type in question, which is capable of accepting and testing any inserted coin, and which will provide a timed interval corresponding to the value of the inserted coin, under all circumstances and without in any instance causing a user to lose an inserted coin or the equivalent time interval.
  • one feature of the invention resides, in a manually activated apparatus for timing with a timer intervals of different length which are selected in dependence upon a characteristic of an inserted coin which is identified by a coin tester, particularly in a parking meter, an improvement wherein the coin tester comprises a combination of a coin receiver adapted to receive coins of different diameter, and a first and a second normally blocked lever biased for movement in mutually opposite directions about a joint axis of rotation into detecting engagement with a plurality of angularly spaced points on the circumference of a coin in the receiver, so as to detect the diameter of such coin.
  • Manually operable means are provided for unblocking the levers for the aforementioned movement, and for subsequent joint angular displacement through a distance which is dependent upon the detected coin diameter.
  • Control means is provided on one of the levers for setting the timer to an interval whose length is a function of the aforementioned distance.
  • the apparatus according to the present invention requires only a single coin inlet slot through which all coins that can be used with the apparatus, are inserted. This means that a user no longer has to determine into which of several slots a particular coin should be inserted; in consequence, the prior-art problem that a user might insert a coin into the wrong slot and the apparatus would not operate for a time interval corresponding to the value of the coin, is avoided. Evidently, this eliminates the possibility of losses which heretofore have been one of the primary difficulties in the use of the prior-art parking meters.
  • each and every inserted coin is supplied to one and the same testing arrangement which is capable of testing all inserted coins and which selects a purchased time interval in dependence upon the coin value that it has detected.
  • the present invention makes it possible to combine all the components required for receiving, testing and determining the value of an inserted coin in form of a separately produceable assembly which can be mounted on a mounting plate of the apparatus, and that the time-selecting and timing components of the apparatus can be mounted as a second assembly group on a second mounting plate, with the two mounting plates being readily connectable.
  • Such an arrangement makes for greater ease and simplicity of assembly, and this is further facilitated in that many of the components involved are of one piece and can be readily produced in a single operation of readily formable materials, so that the overall cost of producing the apparatus according to the present invention is significantly smaller than in the prior art. Hence, the apparatus according to the present invention can be produced and sold more economically.
  • the apparatus receives a coin that has been inserted through the single coin slot, in a cage-like component.
  • the coin which is initially loosely received in the cage-like component is shifted to a position in which it can be tested for its diameter and, hence, for its value.
  • This position is obtained when the coin is engaged in testing relationship by three boundary surfaces bounding the interior of the cage, which surfaces are movable relative to one another and are inclined at predetermined angles. The surfaces assume, during the testing operation, an angular position relative to one another which is characteristic of the diameter of the inserted coin.
  • the apparatus according to the present invention assures that the coin is engaged on at least three different circumferential locations, and an angular position of levers carrying the components involved is set in dependence upon the determined diameter of the coin.
  • This makes it possible to determine very precisely the diameter of any type of coin.
  • the apparatus according to the present invention permits a much more precise testing of the diameter of a precisely circular coin, due to the three-point engagement with the coin.
  • the invention also makes it possible to determine quite precisely the diameter of a non-circular coin, for instance the octagonal coins which are in use in some countries.

  • the apparatus according to the present invention uses two mounting plates 1 and 2 (compare FIGS. 1 and 6) each of which carries an assembly composed of several of the various units. This makes for a simple manufacture and mounting of the two assemblies, and to complete the final assembly of the apparatus it is merely necessary to connect the two plates with one another so that the assemblies carried by the respective plates 1 and 2 will come into cooperative relationship.
  • all components which constitute part of the coin processing unit C are mounted on one of the mounting plates 1, here on the mounting plate 1 which faces the manually operable element, namely the knob or handle 15.
  • the components associated with the coin processing unit C are illustrated in FIGS. l-5 and include the coin accepting unit A, the coin-diameter testing unit B with its testing elements E, and the control elements D which initiate the selection of time and the operation of the timer in dependence upon the identified value of an inserted coin.
  • the cooperation with the assembly on the second mounting plate 2, namely the time selecting unit F, the timing unit G and the indicating unit H, is effected by means of pivotable pawls 100, 101 and 102.
  • the second assembly composed of the units F, G and H which are mounted on the mounting plate 2, is illustrated in more detail in FIGS. 6-9.
  • the mounting plates 1 and 2 are provided with projections 3 (see FIG. 6) which may be of one piece with them and which have centering and retaining portions 4, 5 and 6 (see FIG. 3) which assure that the two assemblies will assume a predetermined fixed relationship relative to one another when the two mounting plates 1 and 2 are connected.
  • FIG. 1 it will be seen that all components of the coin processing unit C and associated elements are exclusively mounted on the mounting plate 1.
  • the latter is formed on its inwardly facing side la, that is the side facing away from the knob 15, with a gear segment 7 that is of one piece with the mounting plate 1 and serves to block return movement of the arrangement, in the manner still to be discussed later.
  • This segment 7 projects from the inner side la and is arcuately curved and concentric with reference to a bore 8 through which the operating shaft 9 extends.
  • the segment 7 is provided with teeth 10.
  • Also of one piece with the mounting plate 1 are ejecting portions 11 and 12 and abutments l3 and 14 (compare FIGS. 1 and 2) and 36, which cooperate with movable components of the coin processing unit C.
  • the front side lb of the mounting plate 1, that is the side facing towards the knob 15, is provided with guide faces 22 (see FIG. 4) which engage-and guide a movable cover 20 of the coin accepting unit A.
  • the coin accepting unit A Details of the coin accepting unit A are shown in FIG. 1, from which it will be evident that this unit A is mounted on the side 1b of the mounting plate 1 which faces towards the user, that is the side at which the knob 15 is located. The knob is mounted on the shaft 9 so as to turn the same when the knob is turned.
  • the unit A includes a removable outer or cover plate 19 which is mounted on the mounting plate 1 by means of screws or similar mounting elements 16.
  • the plate 19 is formed with a single slot-shaped opening 18 whose length and width corresponds to the diameter and width of the largest coin which the apparatus is intended to accept.
  • the coin is identified throughout the drawing with reference character M.
  • the difficulties associated with the prior art when coins of a certain value were inserted into a slot intended for a coin of a different value, are avoided with the construction according to the present invention.
  • a movable cover 20 is provided which is located behind the outer plate 19 and which is provided with a slot-shaped opening 21 identical to the opening 18.
  • the cover 20 can be moved with reference to the plate 19 to and from a position in which the openings 18 and 21 are in full registry with one another, so that a coin M can be inserted through the two of them.
  • the movable cover 20 is provided between the guide faces 22 for the aforementioned sliding movement, and this guidance prevents any movement of the opening 2110 a position in which it might be skew with reference to the opening 18.
  • Elongated openings 23 and 24 are provided in the movable cover 20, and the screws or analogous elements 16 extend through the openings 23 and 24 and are secured in the mounting plate 1.
  • a follower 25 is provided on the movable cover 20, extending transverse to the direction of movement of the latter and passing through a cutout in the mounting plate 1, to extend axially into a cam track 26 which is formed on a lever 27.
  • FIGS. 4 and 4a show particularly clearly that the lever 27 is mounted on the shaft 9 so as to turn with but delative to the same, and that it can be turned by turning of the handle or knob (in counterclockwise direction in FIG. 1) through a certain angular distance against the restoring force of a restoring spring 28.
  • the cam track 26 is in the starting position, which is also the starting position of the coin processing unit C
  • the follower 25 is located in a first surrounding part of the cam track 26, in which the follower 25 is held in one of its two positions, namely the lower extreme position.
  • the coin accepting unit A is automatically ready to accept a coin M, that is the openings 18 and 21 are in full registry with one another.
  • the cam track 26 curvature increases radially over only a few degrees of arc by an extent which is necessary to assure that in cooperation with the follower 25 it shifts the movable cover to the other extreme end position, in which the opening 21 is outof registry with the opening 18 and the insertion of coins into the coin accepting unit A is impossible.
  • the, latter is formed with a concentric arcuate portion 26/ l which is so configurated that during further movement the movable cover 20 will remain in its coinblocking position, so that the cover 20 can return to a position in which its opening 21 is in registry with the opening 18, only when the knob 15 is subsequently returned (in clockwise direction in FIG. 1) to its starting position, during which movement the portion 26/2 of the cam track 26 engages the follower and shifts the same and thereby the movable cover 20, back to the starting position in which the openings 18 and 21 are in registry and permit the insertion of another coin.
  • the coindiameter testing unit B When the knob 15 is in its starting position, the coindiameter testing unit B is located immediately inwardly behind the openings 18, 21. It is suitable for testing all of the coins that can be accepted by the apparatus, that is all of the coins that can be inserted through the openings 18, 21.
  • the unit B constitutes a part of the coin processing'unit C and has the purpose of accepting an inserted coin M, and to determine its value. The value is determined as a function of the determination of the coin diameter.
  • FIG. 10 shows diagrammatically, the coin diameter is determined by engaging the coin M at three circumferentially spaced locations of its periphery by means of mutually inclined abutment faces 46, 47 and 48, of which the latter is movable toward and away from the abutment face 46.
  • FIG. 3 shows that the cage-like structure 29 is formed by a U-shaped profiled member 30 which is mounted on an arm 31 of a lever 34, as most clearly shown in FIG. 2.
  • the U-profiling faces'inwardly and its open side faces downwardly; that'is the inner sides of the arms and bight of the member 30 are formed with the slotshaped recesses 32, and the open side of the overall U- shaped configuration faces downwardly.
  • One arm 35 of the member 30 is located directly behind the opening 21 due to the fact that the lever 34 is normally maintained in engagement with the abutment 36 by a biasing spring 37.
  • This arm 35 is formed with a cutout 38 corresponding in its dimensions to the dimensions of the openings 18 and 21 and which extends into the bight portion.
  • a cover 39 of vibration and sounddamping material e.g. rubber or rubber-like synthetic plastic material, is applied onto the abutment 36 for obvious reasons.
  • a double-armed leaf spring 40 is provided, one arm of which maintains the lever 34 in the starting positiorrthereof against the abutment 14 as shown in FIG. 2, whereas a second arm 41 of the spring 40 cooperates with an additional leaf spring 42 to act upon a coin detent member 43.
  • the latter is pivotably mounted on the member 30 by means of angled mounting portions 44 and has a further right-angular portion 45 which extends into the cage-like structure 29 (see FIGS. 2, 4) and is provided with the abutment face 46.
  • a radially extending control arm 49 is provided on the coin detend 43; when the lever 34 turns with the shaft 9, the arm 49 will in the terminal phase of this turning movement engage a stationary abutment 50 of the ap paratus, whereby the coin detent 43 is pivoted in clockwise direction (FIG. 3) counter to the biasing effect of the spring 40, 42. This results in a retraction of the abutment face 46 out of the cage-like structure 29, so that the coin M can now pass through the thus-opened side of the cage-like structure 29 under the pushing influence of the lever 27. At the moment of ejection the coin M receives a certain amount of acceleration due to the released force of the spring 37 with reference to the levers 27 and 34.
  • the second abutment face 47 which extends substantially at right angles to the abutment face 46, is formed by an arm 51 of the member 30 which is located opposite the inlet opening 38 in'the arm 35. It is provided with a groove 32 which is bounded by the portions 51/1 and 51/2, so as to guide an inserted coin M in order to assure that the latter is placed by the action of the lever 27 into a proper test position intermediate the abutment faces 46, 47 and 48. The latter is concave and the coin M rests on it once the coin has been inserted into the structure 29.
  • the abutment face 48 is inclined at an acute angle with reference to the faces 46, 47 andis movable relative to the same, as indicated by the arrow in FIG. 10 and as shown in FIGS. 2, 3 and 4 in'particular.
  • the abutment face 48 is provided on a slide member 52, as will be described later.
  • This arrangement of the abutment faces thus provides for a determination of the coin diameter by engagement of the coin periphery at three circumferentially spaced points when the coin is in a certain predetermined orientation, and thus makes possible an exact determination of the coin diameter by the summation of several individual items of information.
  • the summation of the three items of information obtained by engaging the coin M at three distinct locations causes a certain angular position of the levers 27 and 34 relative to one another, which levers carry the abutment faces 46, 47 and 48.
  • This angular position can be obtained by operating the knob 15, that is by turning it counterclockwise in FIG. 1 after the coin has been inserted. Due to the constant biasing force of the spring 37, which exerts a biasing action on the levers 27 and 34 in mutually opposite directions, the once-set relative angular position of the levers 27 and 34 is maintained.
  • the abutment face 48 is formed on a slide member 52; the latter is pivotable on the lever 27 and arrestably displaceable between two end positions I and 1] (FIGS. 1 and 4).
  • the slide member 52 is of one-piece construction and is formed with projections 53 and 54 which are flexible, that is whose diameter can be varied due to the fact that they are provided with axial slots.
  • the projections 53 and 54 serve to mount the slide member 52 for movement in the operating direction, for which purpose they extend arcuately curved elongated openings 55, 56 formed in the lever 27.
  • the free end of each of the projections 53, 54 is formed with an enlarged head 57 of increased diameter, which has a conical portion 58 as shown in FIG. 4b.
  • the initial function to be performed by the apparatus according to the present invention upon turning of the knob from the starting position thereof, is to determine whether or not a coin M is present in the coindiameter testing unit B, or whether the knob 15 is being turned without a coin having previously been inserted.
  • the slide member 52 is in operative connection with control members 62, 69 of the coin processing unit C, in such a manner that in dependence upon the presence of an inserted coin M the slide member 52 can be displaced, by turning of the knob 15, from its first position I into a second position II.
  • This displacement permits cooperation between the control member 62 and the teeth 10 of the tooth segment 7, which together constitute a blocking arrangement against a return movement of the knob 15, and also permits cooperation between the control member 69 and the coin holding member 73 which together act to transport the inserted coin M into the (non-illustrated) coin collecting box.
  • the slide member 52 When the coin M has been ejected from the cage-like element 29, the slide member 52 returns the control member 62 to the original position thereof, as the slide member 52 itself returns to its starting position I.
  • the lever 27 is maintained in its starting position by the restoring spring 28, in which it engages the abutment 13 via an interposed portion 61 of the slide member 52.
  • the latter is automatically movable to its first position I as a result of its engagement with the abutment 13 (see FIG. 4), and this first position corresponds to an angular displacement of the slide member 52 through a predetermined angular distance in the operating direction.
  • the end of the slide member 52 remote from the abutment face 48 is provided with elements which serve to operate the control members 62 and 69.
  • the control member 62 constitutes a part of the earlier mentioned blocking arrangement against reverse movement, and the control member 69 together with the member 73 constitute a transporting arrangement for transporting the coin M. Both of these become operative only in dependence upon the insertion of a coin M into the unit D, and the operation of the knob 15. Only after the unit C has completed its own operation, can the control member 62, 69 and the slide member 52 be returned to their starting position in which another coin can be inserted into the unit A.
  • the blocking arrangement for blocking the return movement utilizes the aforementioned control member 62 which is of one piece and which is constructed with a resiliently yieldable arm 63 and with two cams 64 and 67, as shown in FIGS. 4, 4a and 4b.
  • the control member 62 is turnably mounted on the lever 27 on a pin 70, and via the arm 63 it is in engagement with a bifurcated bracket 65 of the slide member 52, so that when the slide member 52 is moved to its position II the tip 66 of the control member 62 can be moved into biased engagement with the teeth 10, thus preventing a return movement of the unit C from an intermediate position into the starting position thereof, and permitting only a further forward movement to the operated position.
  • the control member 69 is also of one piece, being constructed as a multi-armed pivoting lever which is also mounted on the pin 70 of the lever 27, and which is in engagement with the slide member 52 (see FIGS. 1 and 4) by means of its arm 74 and a leaf spring portion which is of one piece with the member 69.
  • a further arm 71 of the member 69 is so arranged that a projection 72 at its free end will move during pivoting of the arm 69 into the range of operation of a coin holding member 73 (see FIG. 1).
  • the lever 69 will automatically be pivoted in such a manner that the projection 72 will cooperate with an inclined surface 76 of the coin holding member 73 which is biased by a spring 77 to a normal rest position.
  • the member 73 is mounted on a pivot 78 in a fixedly mounted bracket 79 and is provided with a portion 80 which can be tilted transversely to the direction of coin movement.
  • the bracket 80 can be tilted out of the coin channel due to the displacement by the control member 69, so that a coin M which is located on the bracket 80 is now free for passage to the non-illustrated coin collecting box.
  • a plurality of followers 82 is provided on the lever 72, and these have the purpose of accommodating the coin processing unit C to any coin size that can be detected by the coin-diameter testing unit (see FIGS. 1 and 4).
  • a displacement distance can be preselected which corresponds to the value of the coin size.
  • This setting is in a certain relation to the relative angular position of the lever 27 and the lever 34, which is in turn determined by the size of the coin in the coin-diameter testing unit B.
  • the lever 27 is provided with a portion 83 in which a plurality of the followers 82 is mounted.

  • a second time segment can be selected on the basis of a non-additive, a degressive or even a progressive angular-range displacement.
  • Non-additive angularrange displacement is intended to mean that the cam 113 can be turned for setting purposes only over a distance corresponding to an entire time interval.
  • a time interval had previously been selected by the insertion of a coin, and that a part of this time interval has expired (e.g. one-half hour of a selected time interval of 1 hour), and if the same value coin is again inserted, then the cam l 13 can move (when the knob 15 is turned) only through a distance corresponding again to another hour.
