Definitions

  • the present invention relates to a crane game machine having a crane type premium article-grasping means which can be moved by an operation of a player who plays a game of grasping a premium article such as a toy, a candy or the like.
  • a crane as a premium article grasping means having a plurality of hooks and a driving mechanism disposed in a housing which has a transparent cover, and an inlet for inserting coins therethrough and a manipulating portion including a starting switch and others to be operated by a player disposed on the outside face of the housing.
  • a player inserts a coin and operates the manipulating portion to move the crane to a desired position on the premium article placing face to grasp a premium article.
  • the hooks grasp well the premium article, the premium article is taken out so that the player can gain it.
  • period and number of times permitting the player to play a game per coin insertion are previously decided.
  • US-A 2 600 849 discloses the prior art crane game machine specified in the preamble of claim 1. According to that realization, the grasping force of the claws is increased by the load of a spring to a guide ring which acts on the claws. The force of hooks for catching a premium article is thereby constant, so there is the problem that it is impossible to increase the chance that the hooks grasp well a premium article and carry the same out.
  • An object of the present invention is to provide a crane game machine which is capable of regulating the ratio or probability of gaining a premium article by making the premium article grasping force of the crane hooks changeable.
  • a crane game machine which comprises a premium article placing face for putting a large number of premium articles thereon, a crane having a plurality of hooks for grasping at least one of the premium articles, a driving mechanism for setting the crane to a position on the premium article placing face and for making the hooks of the crane grasp at least one of the premium articles in response to the operation for initiating the movement by an operator, and a grasping force changing means for changing the premium article grasping force of the crane hooks.
  • the driving mechanism moves the crane to a position on the premium article placing face and closes the polurality of hooks.
  • the hooks grasp well the premium article, the player can gain the premium article.
  • the grasping force changing means sets up the grasping force of the crane hooks relatively small, the ratio or probability of gaining premium article is low, while when the grasping force changing means sets up the grasping force of the crane hooks large, the ratio of probability of gaining premium article becomes high.
  • Fig. 1 is a perspective view showing an appearance of a crane game machine constituted so as to put a large number of premium articles on a turn table disposed in a housing.
  • the crane game machine has a box-type housing 1, which has a transparent glass plate 2 fixed at front, right and left sides of upper part thereof so as to see inside therethough. Inside of the housing 1, there is disposed a disc- type turn table 3 at almost same height as a lower end of the glass portion 2. On an upper surface of the turn table 3 are placed a large number of premium articles 4. Above the turn table 3, a crane 5 is hung.
  • the crane 5 has four hooks 6 extruding downward. As mentioned in detail later, the crane 5is driven up and down by a driving mechanism accommodated inan upper portion of the housing 1 and the hooks 6 are opened and closed synchronously with up and down movement of the crane 5.
  • a lower portion of the front of the housing 1 under the glass 2 is formed as a door 7 openable rotatively right side as shown in Fig. 2.
  • the door 7 is provided at upper portion thereof with two coin insertion inlets 8 and 9, a starter switch 10 as a manipulating portion to be operated by a player when the game starts, and a handle 11 for rotating the turn table 3 by hand as mentioned later, which are attached so as to be operable from outside, respectively.
  • the number of times of game to be able to play per coin insertion is set two kinds, once and a plurality of times, for example, four times, and in order to enable the player to select either of them, two coin insertion inlets 8 and 9 are provided.
  • a coin detector provided inside is actuated and a controller of the game machine is set up so as to play the game once or a plurality of times. Also, in this game machine, there is disposed at a position lower than the starter switch 10 a speaker 12 for generating predetermined effective sound during the movement of the crane.
  • the door 7 has a knob 13 attached to a central portion of the left side.
  • a pair of up and down safety catches 14 and 15 provided on a rear face of the door 7 as shown in Fig. 2 are turned to lock or unlock the door.
  • the door 7 has a rectangular opening 16 disposed at the center for taking out a premium article grasped by the crane 5 as mentioned later.
  • the opening 16 is closed with a cover plate 18 of a premium article receptor member 17 attached on the rear face of the door 7.
  • the cover plate 18 is provided with a grip 19 on its outside.
  • the premium article receptor member 17 consists of the opening cover plate 18 positioned at the front, semi-circular side plates 20 and 21 extruding perpendicularly backward from both ends of the cover plate 18, a bottom plate 22 inclined downward from a lower end of the cover plate 18 and extruding along lower edges of both of the right and left side plates 20 and 21, and a stopper plate 23 archedly curved downward from a rear edge of the bottom plate 22.
  • the premium article receptor member 17 is attached to the door 7 freely rotatably in a direction perpendicular to the door 7 by a pair of hinge pins 24 provided on the rear face of the door 7 at angles of the right and left side plates 20 and 21.
  • each of the right and left side plates 20 and 21 has an arched cutout 25 in which a guide pin 26 provided extrudingly in the opening 16 of the door 7 slidably fits.
  • the outcut 25 acts as a guide when the premium article receptor member 17 is moved rotatively.
  • the premium article receptor member 17 has a function to close the opening 16 by the cover plate 18 when the end of the stopper plate 23 extending downward abuts on the rear face of the door 7 as shown in Fig. 2, and to receive and hold the premium article which has been grasped and taken off by the crane 5 as mentioned later, at the bottom plate 22. In this state, if the grip 19 is pulled from outside of the door 7, the premium article receptor member 17 is rotated to uncover the opening 16 so that the player can take out the premium article.
  • the handle 11 has a shaft 27 acting as a center of rotation, which is penetrated through the door 7 and is fixed with a frictional roll consisting of a roller 28 made of a highly frictional material such as a rubber at the end.
  • the turn table 3 is attached rotatably on a base 31 which can be pulled out to our side (front side) from the inside of the housing 1 when the door 7 is opened.
  • the base 31 is partly cut out at a front edge.
  • the roller 28 rotating with the handle 11 as one body is positioned at the cutout portion of the base 31 and abuts on the fringe of the lower face of the turn table 3. Therefore, if the handle 11 is rotated, the turn table 3 is rotated due to friction with the roller 28. However, if the handle 11 is rotated quickly, slip is generated around the roller 28, resulting in impossibility for the turn table 3 to follow the rotation of the roller 28. Thus, the positioning of the turntable 3 to the crane 5 becomes more difficult and hence, the amusement of the game can be enhanced.
  • the turn table 3 has an opening 33 on its circular face for discharging the premium article 4 holded by the hooks 6 of the crane 5 and correspondingly the base 31 has an opening 34. Further, in the housing 1, under the opening 34 of the base 31 is formed a passage 35 for leading the premium article 4 to the bottom plate 22 of the premium article receptor member 17 mentioned above.
  • the crane 5 has a domed casing 41 accommodating four hooks 6a, 6b, 6c and 6d freely openably and closeably, each two of which are faced each other, as shown in Figs. 4 to 6.
  • a top portion of the casing 41 is formed as a cylinder 42, which is provided at upper position of the side with a pair of projections 43a and 43b, each of which has a perforation.
  • a pair of rings 44a and 44b passed through the perforations of the projections 43a and 43b, respectively, are connected to another pair of rings 46a and 46b through small rings 45a and 45b, and also an end of a first chain 47 is connected to the pair of rings 46a and 46b.
  • a second chain 48 is connected to an upper end of a movable member 50 accommodated in the casing 41 freely movably up and down.
  • a lower end of the movable member 50 is extruded in four directions, and to the four extruding end portions are connected projecting points extruding almost rectangularly from the bases of the hooks 6a to 6d, respectively, by hinge pins 51 freely rotatably.
  • the bases of the hooks 6a to 6d are connected to ends of connector rods 53 by hinge pins 52, and other ends of the connecting rods 53 are connected to the casing 41 by hinge pins 54, respectively.
  • the lower end of the cylinder portion 42 are extruded downward inside of the casing 41.
  • a third chain 49 is connected to an upper end of a cylindrical weight member 55 positioned above the casing 41 by a pair of rings 56a and 56b.
  • the third chain 49 is set up in the state where the weight member 55 is kept above the casing 41 or put on the casing 41 by a solenoid provided as a grasping force changing means which can change the force that the hooks 6 of the crane 5 grasp the premium article 4, as mentioned later.
  • the above-mentioned three chains 47, 48 and 49 are passed upward through a cylinder 57 hung from the inner ceiling of the housing 1 as shown in Figs. 1 and 4 and are connected to a driving mechanism 60 (Fig. 7) accommodated in the upper part of the housing 1.
  • the driving mechanism 60 comprises a rotation power unit 61 including a motor and driving gears, a first link 63 which is fixed at one end to a rotation output shaft 62 of the rotation power unit 61, and a second link 65 which is connected to the first link 63 so as to form almost L-shape by a connecting rod 64 provided at another end of the first link 63.
  • the driving mechanism 60 is fixed to a mounting plate 66 vertically attached in the upper portion of the housing 1.
  • An upper end of the first chain 47 which is connected to the casing 41 of the crane 5 as mentioned above, is connected to a free end of the second link 65 by a second connecting rod 67, while upper ends of the second chain 48 and the third chain 49 are connected to the first connecting rod 64 by which the two links 63 and 65 are connected in L-shape. It also should be noted that the upper end of the third chain 49 may be connected to a second connecting rod 67.
  • the solenoid 70 As the grasping force changing means for changing the premium article grasping force of the hooks of the crane 5.
  • the solenoid 70 has a plunger 72 equipped at top with a hook 71 which is engaged with the third chain 49 and a spring 73 for extruding the plunger 72 when the solenoid 70 is not electrically supplied.
  • the solenoid 70 is electrically supplied from a predetermined electric source via a manual switch or a drive control circuit (not shown). In the state where the plunger 72 is extruded as shown in Fig.
  • the hook 71 of the top of the plunger 72 pushes the third chain 49 to impart a tension, thereby keeping the weight member 55 above the casing 41 by the third chain 49, as shown in Fig. 5.
  • the solenoid 70 is electrically supplied, the plunger 72 is moved back against the counterforce of the spring 73 to release the tension of the third chain 49. Accordingly, as shown in Fig. 6, the weight member 55 is put on the casing 41 to add a weight thereto.
  • the driving mechanism 60 pulls the first chain 47 to keep the crane 5 at the upper position and hangs it down as shown in Fig. 1, while the second chain 48 is not pulled so that the movable member 50 of the crane 5 is positioned down as shown Fig. 5(A) and the hooks 6a to 6d are opened.
  • the solenoid 70 is not electrically supplied and the plunger 72 is extruded as shown in Fig. 7 to add a tension to the third chain 49 by the hook 71 of the top, whereby holding the weight member 55 above the casing 41.
  • the player turns the handle 11 to rotate the turn table 3 for bringing a desired premium article among a lot of the premium articles 4 placed on the upper surface of the table right under the crane 5.
  • the rotation of the handle 11 is communicated to the turn table 3 via the roller 28 consisting of a friction wheel, so that if the handle 11 is rotated quickly or stopped suddenly, the roller 28 is slipped and hence, it becomes difficult to rotate the turn table 3 in accordance with the handle operation. Therefore, the amusement of the game is increased.
  • the starter switch 10 When the positioning of the turn table 3 by the handle operation mentioned above is completed, the starter switch 10 is then pushed. Thus, the rotation power unit 61 of the driving mechanism 60 is initiated to rotate the almost L-shaped links 63 and 65.
  • the crane 5 is fallen down by the first chain 47 which hangs down the crane 5.
  • the fall of the crane 5 is continued until the fall of the first chain 47 due to the rotative movement of the second link 65 is stopped.
  • the crane 5 is placed at a position where the hooks 6 can grasp the premium article 4 on the turn table 3.
  • the length of the chains and links and the positions thereof are previously decided so that the almost L-shaped links 63 and 65 pull the second chain 48 instead of the first chain 47 to take up the movable member 50 in the crane 5 and to close the hooks 6a to 6d.
  • the hooks facing each other are rotatively moved in the direction closing each other to close the hooks 6.
  • the player turns the handle 11 to rotate the turn table 3 to bring the opening 33 to right under the crane 5 before the rising crane 5 reaches the upper position.
  • the premium article 4 falls to the passage 35 though the opening 33 of the turn table 3 and the opening 34 of the base 31 and is received by the premium article receptor member 17. Accordingly, the player pulls the grip 19 to uncover the opening 16 of door 7 and can take out the premium article.
  • the driving mechanism 60 stops in the state where the crane 5 having the hooks opened returns to the upper position.
  • the crane 5 and the driving mechanism 60 repeat the above-mentioned actions corresponding times.
  • the casing 41 When the casing 41 is relatively light, the casing 41 is pushed up with ease correspondingly so the premium article grasping force of the hooks becomes also weak. As the result, even if the hooks grasp the premium article well on the premium article placing face, the probability of taking up the same is low and the premium article gaining ratio is low.
  • the weight member 55 is placed on the casing 41 to add the weight by releasing the tension imparted to the third chain 49 in the above-mentioned embodiment. That is, for example, the handler for the crane game machine turns on the electric power switch of the solenoid 70 to electrically supply to the solenoid 70, thereby pulling back the plunger 72 to release the tension of the third chain 49. As the result, as shown in Fig. 6(A), there is obtained a state where the weight member 55 is put on the casing 41 to add the weight thereto.
  • the player operates the starter switch 10 to initiate the movement of the rotation power unit 61 of the driving mechanism 60, as in the case of Fig. 5, the crane 5 is descended to the position on the premium article placing face to close the hooks 6a to 6d as shown in Fig. 6(B).
  • the premium article grasping force is increased by the weight of the weight member 55, the probability to take up the premium article 4 becomes larger than in the case of Fig. 5, resulting in high facility of gaining premium article for the player.
  • the operation for increasing the ratio of gaining premium article is carried out by driving the solenoid 70 in a ratio of, for example, one tenth or one twentieth, that is, one time per 10 or 20 games.
  • the solenoid 70 is provided with a drive control circuit to control the electrical supply in above-mentioned ratio.
  • Fig. 8 shows a constitution in which in the crane 5 of the above-mentioned embodiment, a spring 58 is interposed between the lower end of the cylindrical portion 42 of the casing 41 and the lower end extruding sidewards of the movable member 50.
  • the force for closing the hooks 6a to 6d that is, the premium article grasping force can be controlled correspondingly to the elastic force of the spring 58.
  • the premium article grasping force of the hooks can also be regulated by controlling the electric current for driving the solenoid so as to change suitably the tension added to the third chain 49 from the solenoid 70 in Fig. 7.
  • the face for putting the premium article is not limited to the disc-typed turn table of the embodiment, but it may be a fixed flat board.
  • the driving mechanism of the crane is constituted so as to transter not only in up and down directions but also forward and backward, and right and left.
  • the gasping force changing means is not limited to those of weight addition system by the weight member as in the embodiment, but it may be one enable to suitably change the closing force of crane hooks.
  • the means of hanging down the crane can be used a rope or the other cord besides . the chain.
