Description

The present invention relates to an attachment or the like that can be attached to and detached from a catch mechanism portion of a prize acquisition device.

Among popular devices in game centers and the like, there are prize acquisition devices called “crane game machines” and “crane-type prize acquisition devices”. This type of prize capturing device includes a mechanism for moving up and down a catch mechanism unit for catching a prize and a mechanism for horizontally moving the catch mechanism unit. Then, the user plays the game according to the rule that, when the user catches the prize by the catch mechanism unit, lifts it, and moves it to a predetermined position, he can get the prize that he holds. Hereinafter, this type of prize acquisition device will be simply referred to as a “prize acquisition device”.

The catch mechanism of the prize capturing device is equipped with two claws (also called claws or arms) as a standard, and how the two claws can grab the prize well is a game. It becomes the point of play. However, the type and size of the prize of the prize capturing device can be variously set by the business operator who operates the prize capturing device, and when using a large prize, the nail portion may be replaced with a size larger than the standard size. It is used by increasing the number of nails. For example, Patent Document 1 discloses a configuration in which three or more claw portions can be attached in various relative positional relationships.

The fixing plate 120k has an insertion hole, and a fixing bolt 126b (see FIG. 6) provided at the center of the pedestal portion 124 in a top view is inserted and tightened with a wing nut or the like. Since the fixing plate 120k is fixed to the pedestal portion 124, the renewal mounting portion 120 is fixed to the pedestal portion 124.

The swinging end portion 120y has the same configuration as the mounting portion 38, and the renewal pawl portion 122 can be detachably inserted and removed. The swing end 120y (renewal mounting part 120) has an insertion hole 120h through which the cross member 106 is inserted. In other words, the replacement mounting part 120 has the insertion hole part 120h that functions as a part of the link part 110.

The hole diameter of the insertion hole portion 120h is set to be slightly larger than the diameter of the cross section circular shape of the cross member 106, and the contact position of the cross member 106 inserted into the insertion hole portion 120h can be freely set along the arc shape. Can be changed. As a result, even if there is a variation in the working accuracy or the assembly accuracy of each part, the renewal mounting part 120 can be smoothly moved up and down by the swing of the alternative part 104.

The renewal claw portion 122 is a renewal claw portion that is connected to the cross member 106 to perform a gripping operation/a gripping unraveling operation in accordance with the elevation of the cross member 106. In the present embodiment, the claw portion 9 has the same configuration as that of the claw portion 9, and the claw portion 9 and the renewal claw portion 122 can be diverted from each other. Of course, the renewal claw portion 122 can be designed as a dedicated part having a different shape from the claw portion 9.

The pedestal portion 124 is a member that serves as a base for mounting the attachment 100 on the drive unit 40. Therefore, an engagement structure for attaching to and detaching from the lower surface of the drive unit 40 is provided on the upper surface of the pedestal portion 124. In the present embodiment, the engagement piece 125 is provided (see FIG. 5). The engaging piece 125 forms a gap between the engaging piece 125 and the pedestal portion 124 for fitting the bent portion provided at the lower end of the drive unit 40.

In addition, the pedestal portion 124 has a plurality of fixing portions 126 to which the renewal mounting portion 120 can be attached, for each one mounting portion 38 (combination of the substitute portion 104, the cross member 106, and the link portion 110) at M locations (M. >N) have.

Specifically, the fixing portion 126 has a positioning hole 126h and a fixing bolt 126b (see FIG. 6). The positioning holes 126h are provided radially from the center of the pedestal portion 124 when viewed from above (see FIG. 7). The fixed part 126 is not limited to this structure. For example, a configuration in which a screw hole for screwing the replacement mounting portion 120 is provided instead of the positioning hole 126h is also possible.

Next, the operation of the catch mechanism section 31 will be described.
As shown in FIG. 2, in the initial state at the start of the game play, the catch mechanism section 31 has the renewal claw section 122 opened. At this time, in the catch mechanism portion 31, as shown in FIG. 4A, the mounting portion 38 is in a state of being swung upward. The alternative portion 104 mounted on the mounting portion 38 is in a state of being integrally swung upward together with the mounting portion 38.

Since the connecting rod 111 of the link portion 110 is connected to the swing end side of the alternative portion 104, when the alternative portion 104 and the mounting portion 38 are integrally swung upward, the connecting rod 111 and The cross member 106 is pulled upward and enters a state. Then, the refurbishing mounting portion 120 connected to the cross member 106 is in a state in which the swing end portion 120y is lifted, and the refurbishing claw portion 122 mounted in this is also in a state of being swung upward. At this time, if the attachment 100 and the catch mechanism portion 31 are viewed as a whole, the renewal pawl portion 122 is in an open state.

When the user performs an operation input to move the acquisition mechanism unit 30 to the lowered position, the acquisition mechanism unit 30 automatically moves the catch mechanism unit 31 after moving according to the operation input by the movement control by the control board 50. Let Then, when the descent is performed, the catch mechanism unit 31 is controlled to perform a grasping operation.

When the gripping operation starts, in the catch mechanism section 31, the control board 50 causes the motor 41 to rotate in a predetermined direction, and the mounting section 38 swings downward. Then, the alternative portion 104 is also swung downward together with the mounting portion 38. Then, when the alternative portion 104 is swung downward, the connecting rod 111 and the cross member 106 descend downward. Then, the refurbishing mounting portion 120 is shaped such that the rocking end portion 120y pivots downward, and the refurbishing claw portion 122 mounted thereto is swung down.

FIG. 9 is a partial transition diagram for explaining the grasping operation of the catch mechanism portion 31, and shows the renewal mounting portion 120, the renewal claw portion 122, and a part of the link portion 110 (1) portion. It is a top view and (2) partial perspective view. The left side of the white arrow shows the state of starting the grasping operation, and the right side of the white arrow shows the state of the middle of the grasping operation.

In the process of the gripping operation, the cross member 106 having an arc shape in a top view descends so as to draw a circular arc in a side view, so that the relative positional relationship between the cross member 106 and the refurbishing mounting portion 120 changes in the gripping process. Specifically, the relative position at which the intersecting member 106 and the insertion hole 120h of the refurbishing mounting portion 120 come into contact with each other changes, and the relative attitudes of the both change, and the crossing member 106 and the connecting rod 111 of the link portion 110 are positioned to be separated from each other. Misalignment occurs. In FIG. 9(1), the black band portion of the cross member 106 shown in the intermediate state diagram of the grasping operation on the right side of the white arrow indicates the contact position in the state of starting the grasping operation (left side of the white arrow). Even if the geometry changes due to such a gripping operation, the hole diameter of the insertion hole 120h is appropriately set so as to allow the cross member 106 to be loosely fitted, so that the relative position and the relative posture are allowed to shift, The renewal claw portion 122 is swung smoothly.

Then, as shown in FIG. 4B, when the mounting portion 38 swings downward until it reaches a predetermined angle, the control board 50 automatically stops the gripping operation. At this time, when the attachment 100 and the catch mechanism portion 31 are viewed as a whole, the renewal claw portion 122 is in a closed state as shown in FIG. Specifically, the plurality of renewal claw portions 122 are in a state in which the tips of the respective renewal claw portions approach each other during the gripping operation.

When the grasping operation is finished, the catch mechanism section 31 is pulled up to the original position again, and is moved to the designated position in the game space 6 (the position above the prize acquisition area where the prize arrangement area parts 18 are not mounted), and the gripping is released there. The operation is started.

When the grabbing operation is started, in the catch mechanism portion 31, the control board 50 reversely drives the motor 41, the mounting portion 38 swings upward, and the alternative portion 104 swings upward integrally with the mounting portion 38. .. Then, when the alternative portion 104 swings upward, the connecting rod 111 and the cross member 106 ascend. Then, the refurbishing mounting portion 120 is dressed in such a manner that the rocking end portion 120y rocks upward, and the refurbishing claw portion 122 mounted thereto is swung up. That is, an operation in which the tip ends of the respective renewal claw portions 122 are dispersed by the grasping and unraveling operation is performed.

When the squeezing operation is completed, the catch mechanism unit 31 is moved to a predetermined initial position in the game space 6, and one play is completed.

As described above, according to the present embodiment, it is possible to realize the new prize acquisition device 10 capable of changing the number of mounted nails and the mounting positions for grasping the prize.

Moreover, if the attachment 100 and the outer case 32 are prepared, the conventional product can be used as it is up to the catch mechanism portion 31, so that the prize acquisition apparatus 10 of the present embodiment can be realized at low cost and in a low man-hour. In addition, since the renewal pawl portion 122 and the pawl portion 9 can both be used, it is not necessary to newly prepare the renewal pawl portion 122, and the existing pawl portion 9 can be used.

Then, the user of the prize acquisition apparatus 10 appropriately changes the number of attachments and the attachment positions of the renewal attachment part 120 to the pedestal part 124 to set the catch mechanism part 31 suitable for the size and shape of the prepared prize 4. You will be able to do it yourself.

Specifically, as shown by the attachment 100B in FIG. 11, of the two cross members 106, only one renewal pawl portion 122 is attached to one side and two renewal pawl portions 122 are attached to the other. By doing so, the three-claw catch mechanism portion 31 can be realized. Further, if two of the two cross members 106 are provided with the renewal pawl portions 122, the catch mechanism portion 31 having four pawls can be realized. Depending on which fixing portion 126 the renewal pawl portion 122 is attached/fixed to, it is possible to freely set up to which position the renewal pawl portion 122 is separated with the tab of the renewal pawl portion 122 being opened. At that time, both the two cross members 106 can be mounted/fixed at the symmetrically left/right mounting positions of the renewal claw portion 122 (see FIG. 12), or at the left/right asymmetrical positions. It is also possible (see FIGS. 5 and 6).

[Modification]
Although the example of the embodiment to which the present invention is applied has been described above, the embodiment to which the present invention is applicable is not limited to the above-described embodiment, and constituent elements can be appropriately added, omitted, or changed.

For example, the shape and number of the cross members 106 can be changed appropriately.
Specifically, focusing on the top view shape, the top view shape of the intersecting member 106 of the above-described embodiment may be a straight line, a bent shape, or a ring shape. Further, if the cross member 106C is a single ring-shaped member as in the attachment 100C of FIG. 12, the top view shape around the outer periphery of the pedestal portion 124 can be an annular member. Further, focusing on the shape of the cross-section of the cross member 106, the cross-section of the cross-member 106 is circular in the above-mentioned embodiment, but it may be configured so that the cross-member 106 as a whole has a flat plate shape. Good.

Also, the configuration of the link unit 110 can be changed as appropriate. For example, the link part 110D of the attachment 100D shown in FIG. 13 includes a first connecting rod 111c, a second connecting rod 111d, and a guide part 113. The first connecting rod 111c is connected at its lower end so as to be vertically swingable on the upper surface of an intersecting member 106D (annular member having an L-shaped vertical cross-section when viewed from above) corresponding to the intersecting member 106 of the above embodiment. The upper end of the second connecting rod 111d is vertically swingably coupled to the lower surface of the cross member 106D, and the lower end thereof is vertically swingably coupled to the distal end of the swinging end 120y of the upgrade mounting portion 120.
